Description

Technical Field

[0001] This utility model relates to the field of workpiece gripping device technology, and in particular to a workpiece gripping fixture. Background Technology

[0002] During the assembly of circuit breakers, the components to be assembled are usually manually picked up by the assembler and placed in the required position before being installed and connected. This method requires the assembler to repeatedly adjust the position to align the workpiece, which is not only time-consuming and labor-intensive, but also prone to dropping due to loose grip, resulting in low assembly efficiency. Utility Model Content

[0003] In response to the shortcomings of existing circuit breaker switch installation, the applicant provides a workpiece gripping fixture with a reasonable structure. The workpiece is placed on the clamping assembly, which then transports it to the fixture frame and assists in installation, saving time and effort and increasing assembly efficiency.

[0004] The technical solution adopted in this utility model is as follows: A workpiece gripping fixture includes a base assembly with a fixture frame and a support, and a clamping assembly that can move up and down on the support. The clamping assembly has several sets of transverse clamping groups and longitudinal clamping groups on its base plate. Each transverse clamping group includes a transversely movable clamping plate and a fixed transverse support plate. The transverse clamping plate is connected to the clamping rod of a transverse clamping cylinder, which can drive the transverse clamping plate to move laterally closer to or away from the transverse support plate. The longitudinal clamping group includes a longitudinal clamping cylinder and a longitudinal clamping plate. Clamping rods extend from opposite sides of the longitudinal clamping cylinder, and longitudinal clamping plates are connected to the clamping rods on both sides. The longitudinal clamping cylinder drives the longitudinal clamping plates on both sides to move longitudinally closer to or away from each other.

[0005] As a further improvement to the above technical solution: The clamp assembly is connected to the bracket via a support assembly, which in turn is connected to the clamp assembly via a pivot. The clamp assembly can rotate around the pivot's central axis.

[0006] The pivot of the support assembly is inserted through the support plate, a bearing is sleeved on the pivot, the bearing is inserted into the bearing seat, and the bearing seat is fixedly connected to the support plate; the support plate is movably connected to the bracket.

[0007] The support plate of the support assembly is connected to the slider, and the bracket is equipped with a vertical guide rail. The slider is mounted on the guide rail and can move up and down. The support plate is equipped with a connecting plate, which is connected to a lifting cylinder. The lifting cylinder can drive the support assembly to move up and down.

[0008] The transverse clamping plate and transverse support plate of the clamping assembly are arranged face to face on opposite sides of the transverse clamping cylinder, and transverse clamping blocks are connected to the side plates of the transverse clamping plate and transverse support plate facing each other.

[0009] The clamping assembly has two longitudinal clamping plates with longitudinal clamping blocks connected to the side plates facing each other.

[0010] The longitudinal clamping block is a V-shaped block.

[0011] The fixture assembly is located above the tooling rack and can be moved toward or away from the tooling rack longitudinally.

[0012] Several sets of transverse clamping groups of the fixture assembly correspond to several assembly stations of the tooling fixture.

[0013] Several sets of transverse clamping groups of the clamping assembly are arranged at transverse intervals on the upper surface of the clamping base plate, and the longitudinal clamping groups are set on one side of the lower part of the clamping base plate, located diagonally below the transverse clamping groups.

[0014] The beneficial effects of this utility model are as follows: This invention uses a clamping assembly to transport the workpiece to be assembled onto the tooling rack and assists in the assembly of the workpiece. The workpiece can be quickly aligned with the assembly position in one step without the need for position adjustment, saving time and effort, and also preventing the workpiece from falling due to insufficient grip, thus improving assembly efficiency.

The bearing 64 is inserted into the bearing seat 65, and the bearing seat 65 is fixedly connected to the support plate 61. One end of the rotating shaft 63 extends from the front of the support plate 61 and connects to the clamp assembly 7. The clamp assembly 7 can rotate around the central axis of the rotating shaft 63 to adjust the angle.

[0025] like Figure 1 , Figures 3 to 5 As shown, the fixture assembly 7 includes a fixture base plate 71, several sets of transverse clamping groups 72, and a longitudinal clamping group 73. The fixture base plate 71 is vertically arranged and fixedly connected to the rotating shaft 63. The several sets of transverse clamping groups 72 and longitudinal clamping groups 73 are arranged on the front of the fixture base plate 71 and extend forward longitudinally. The several sets of transverse clamping groups 72 are arranged at intervals along the transverse direction on the upper surface of the fixture base plate 71, and the several sets of transverse clamping groups 72 correspond to several assembly stations of the tooling frame 2. The longitudinal clamping groups 73 are arranged on one side of the lower part of the fixture base plate 71, located diagonally below the transverse clamping groups 72.

[0026] Each set of transverse clamping units 72 includes a transverse clamping cylinder 721, a transverse clamping plate 722, and a transverse support plate 723. The transverse clamping cylinder 721 and the transverse support plate 723 are fixedly connected to the fixture base plate 71.

The transverse clamping plate 722 and the transverse support plate 723 are arranged face-to-face on opposite sides of the transverse clamping cylinder 721. The transverse clamping cylinder 721 drives the transverse clamping plate 722 to move laterally closer to or away from the transverse support plate 723.

A longitudinal clamping plate 732 is connected to each clamping rod. The longitudinal clamping cylinder 731 drives the two longitudinal clamping plates 732 to move closer to or further away from each other in the longitudinal direction. A longitudinal clamping block 733 is connected to the side of the two longitudinal clamping plates 732 facing each other.
