Tool-support With Means To Move Tool Relative To Tool-support Patents (Class 408/146)
  • Patent number: 11219149
    Abstract: A memory device memorizes a link between an orientation of a leaded component supported on a component support section and a type of component holding tool used for holding the leaded component of the orientation is memorized in a memory device. Also, the component support section on which multiple leaded components are scattered is imaged by an imaging device, and orientations of leaded components supported on the component support section are identified based on the captured image data. Then, the component holding tool of a type memorized as being linked to the identified orientation of leaded component is decided as the component holding tool for holding the leaded component. By this, it is possible to exchange a component holding tool according to an orientation of a leaded component, thus it is possible to hold leaded components of various orientations using component holding tools.

    Abstract: An improved system for inserting blind attachments has an entry point and an exit point for a seal. The seal enters by way of the entry point and continues its guided course by being moved by a pair of servo pullers. A linear drive servo drill makes a first hole into the seal and, as the seal is moved by the servo pullers, the first hole is in position to have a blind attachment inserted therethrough byway of an insertion tool. At the same time that the blind attachment is inserted, a second hole is made in the seal by having the servo drill moved at the appropriate location.

  • Patent number: 8245610
    Abstract: A device for cutting bar-shaped or tubular workpieces (1, 27), for example a peeling machine, is presented, in which, for the first time, the advance of the tools (7, 26, 44, 46) is brought about by a relative rotation between a toolholder (3, 25, 45) carrying the tools (7, 26, 44, 46) and an advancing sleeve (4, 24, 47). The toolholder (3, 25, 45) and advancing sleeve (4, 24, 47) are driven via gearwheels (19, 18) arranged on the same gear shaft (17) and having an oppositely oriented helical toothing. By means of an axial movement of the gear shaft (17), a relative rotation between the toolholder (3, 25, 45) and advancing sleeve (4, 24, 47) is achieved on account of the helical toothing. Moreover, it is proposed to use milling cutters (26, 44) as tools.

An elongated cylindrical insert has a throughbore or collet pocket and the insert has an outer diameter larger than the inside diameter of the body cylindrical bore. Thus, the insert is insertable into the body cylindrical bore only when the body front nose is heated to a predetermined temperature at which temperature the body thermally expands to an extent that the inside diameter of the body bore is greater than the outer diameter of the insert. Upon subsequent cooling of the body, the body and insert are attached together. A collet is then used to removably and coaxially secure the tool shank to the insert within the insert throughbore.

Radial eccentricity of the tool can thereby be corrected. Furthermore, between the first and second parts of the toolholder, two rings are disposed coaxially with, and rotatingly about, the axis of rotation. These rings have annular surfaces, one of which is inclined relative to the other at a certain angle. By mutual rotation of the two rings, the first part of the toolholder can be inclined relative to the second part, whereby an angular error of the tool can also be corrected.

  • Patent number: 5752789
    Abstract: The invention provides a unique approach to solving a peck feeding problem in limited access areas restricting the drilling unit size. It uses a power transmission system which is comprised of a pinion gear driven by a motor source. The pinion gear drives a bevel gear that is free to travel along a polygon quill. A quill had is located on one end of the quill to house the drill. The opposing quill end is attached to a guide bushing assembly. The guide bushing assembly is connected to a bell crank mechanism that is actuated and controlled by a pneumatic piston and hydraulic speed control system. The power transmission system, and the pneumatic power transfer system combined produce a pecking cycle for drilling precision holes within a confined set-up space of 5.5 inches in a preferred embodiment. It preferably has a drill stroke up to 1 inch deep, and is capable of producing a "pecking" action which is unique for right angle drilling equipment in limited access applications.

  • Patent number: 4615091
    Abstract: A method of processing a scroll member having a spiral wrap and an end plate which is conducted by effecting a shaving on at least one side surface of the spiral wrap by a tool while applying to the tool both of an axial small force and an ultrasonic oscillation simultaneously. An apparatus is proposed which comprises a shaving tool having a spiral groove of the same configuration as the spiral wrap, and a cutting edge portion formed on at least one side edge of the groove over the entire length of the side edge. A tool supporting device supports the shaving tool, and a blank supporting device supports a scroll blank such that the scroll blank opposes to the shaving tool. A device is connected to the tool supporting means and is adapted to impart to the tool a pressing force necessary for effecting the shaving, and an ultrasonic oscillation generating device is adapted to impart an ultrasonic oscillation to one of the tool or the blank.

  • Patent number: 4063843
    Abstract: A shank for an adjustable boring bar is disclosed herein having first and second members telescopically engaged in a nonrotatable relation from one to the other with one of the members having mounted thereon an axially adjustable abutment means such that rotation of the abutment means on one member provides relative axial movement between the first and second members. A recess is shown formed on the outer surface of the innermost telescopically engaged member, the recess having a declining surface in the direction of the abutment means such that a clamp element located and engaged in the outermost telescopically engaged member is operable downwardly to engage said declining surface and hold the first and second members in a firm abutting relationship.

  • Patent number: 3981607
    Abstract: A boring bar having a removable indexable cutting insert with a plurality of cutting edges is disclosed. The cutting insert is held in place in the bar by a locking finger on an insert clamp which is locked into place by a ball which is wedged against a release pin that engages the clamp. The ball may be moved so as to allow the pin to move, thereby releasing the force applied by the clamp whenever the insert is to be indexed or whenever a replacement of the insert is required. This is achieved by either manual or hydraulic control of a wedge shaft that engages the ball.
