Abstract: An assembly apparatus includes a spline sleeve defining a central hole having an inner surface defining a plurality of first and second sliding grooves, a first connecting member and a second connecting member positioned on opposite ends of the spline sleeve, a sliding member sildably received in the spline sleeve and having at least one first key portion slidably received in the corresponding first sliding groove, a rotation member rotatable relative to the sliding member and including a plurality of second key portions selectively slidably engaged in the corresponding first sliding grooves and interfering with the corresponding second sliding grooves, a first elastic member abutting the first connecting member and the rotation member, a second elastic member abutting the second connecting member and the sliding member, and a knockout pin assembly fixed to the sliding member and slidable relative to the second connecting member.

Abstract: An automatic conveying device includes a conveyer bracket, a wheel assembly, a transmission mechanism, and a loading assembly. The wheel assembly is rotatably assembled to a bottom portion of the conveyer bracket for supporting the conveyer bracket. The transmission mechanism is assembled within the conveyer bracket and connected with the wheel assembly, thereby driving the wheel assembly to rotate. The loading assembly is mounted upon the conveyer bracket and movably assembled with the transmission mechanism, for accepting objects as a load and driving the transmission mechanism to work. The loading assembly moves downward relative to the conveyer bracket under the weight of the objects placed on the loading assembly, and is capable of moving upward back to its original position, when the objects are removed.

Abstract: A joint structure includes a sleeve, a connecting shaft, a plurality of elastic pieces and a cross-limiting stopper. The sleeve defines a receiving shaft hole and a first cross slot communicating with the receiving shaft hole. The connecting shaft is partially assembled and received within the receiving shaft hole of the sleeve, the connecting shaft defines a second cross slot corresponding to the first cross slot. The plurality of elastic pieces is elastically received within a space formed between the sleeve and connecting shaft. The cross-limiting stopper is mounted to and partially received within the second cross slot, and partially received in the first cross slot, to enable the connecting shaft to be radially and adjustably installed within the sleeve and prevent the connecting shaft from rotating relative to the sleeve.

Abstract: A robotic manipulator for clamping a workpiece includes a power source, a first rotary member, and a clamping mechanism. The first rotary member is connected to and rotated by the power source. The clamping mechanism is non-rotatably connected to the first rotary member and includes a first clamping member and a second clamping member capable of coupling to and decoupling from the first clamping member. The first clamping member and the second clamping member are coupled to each other. A receptacle is defined between the first clamping member and the second clamping member to receive the workpiece. The receptacle has a shape and size substantially the same as the workpiece.

Abstract: A support stand includes a support member, and a connecting module assembled on the support member. The connecting module includes a first adjustment member, a first connection member rotatably connected to the first adjustment member, a second adjustment member assembled on the support member, a second connection member rotatably connected to the second adjustment member, and a fixing member connecting the first adjustment member and the second connection member. The connecting module further includes two first clamping members assembled on the first adjustment member to clamp the first connection member, and two second clamping members assembled on the second adjustment member to clamp the second connection member. The first and second clamping members are capable of adjusting the rotating angle of the first and second connection member around a first and second axis, respectively. An imaging measurement device utilizing the support stand is also provided.

Abstract: A transmission mechanism includes a threaded fastener and a nut assembly. The nut assembly is sleeved on the threaded fastener, and includes a first nut, a second nut, and an elastic member. The first nut forms two receiving portions, and the second nut defines two receiving cutouts. The elastic member is positioned between the first nut and the second nut. The receiving portions are received in the receiving cutouts, such that the first nut and second nut move only along an axis of the threaded fastener. The elastic member is compressed by the first nut and the second nut, to generate an elastic force exceeding a component force along the axis of the threaded fastener of an external force for rotating the first nut or the second nut.
