Embodiment Construction
[0011] The present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as figure 1 , figure 2 As shown, the present invention provides a fixture for processing an inner hole workpiece, which includes a base 1, a connecting plate 2, a driving rod 5 and a jaw set arranged on the outside of the connecting plate 2, wherein the base 1 is provided with an arc-shaped mounting plate 3. There is a fixed plate 4 between the base 1 and the arc-shaped mounting plate 3, and the connecting plate 2 is separately arranged on both sides of the arc-shaped mounting plate 3. The lower end of the connecting plate 2 is connected with the fixed pin 6 set on the upper end of the driving rod 5 respectively. The two ends are fixedly connected, the base 1 is provided with a movable groove 7 for the drive rod 5 to move up and down; the jaw group includes a left jaw 8 and a right jaw 9, and the left jaw 8 and the right jaw 9 are hinged on the arc On th...

The invention relates to the technical field of clamping devices, in particular to an inner hole workpiece machining clamp. The inner hole workpiece machining clamp comprises a base plate, connectingplates, a driving rod and clamping claw sets arranged on the outer sides of the connecting plates. An arc installation plate is arranged on the base. The connecting plates are arranged on the two sides of the arc installation plate correspondingly. The lower ends of the connecting plates are fixedly connected with the two ends of a fixing pin arranged at the upper end of the driving rod correspondingly. The base is provided with a movable groove for the driving rod to move vertically. The clamping claw set comprises a left clamping claw and a right clamping claw, wherein the left clamping clawand the right clamping claw are hinged to pin shafts arranged on the two sides of the arc installation plate. A bar-shaped hole is formed in the middle portion of the connecting plate and is in sliding fit with the pin shafts in the axial direction. An extrusion pin is arranged at the upper end of the connecting plate, and the two ends of the extrusion pin abut against the left clamping claw andthe right clamping claw correspondingly. A torsion spring is arranged above the clamping claw set, and the torsion spring is connected with the clamping end of the left clamping claw and the clampingend of the right clamping claw correspondingly. The inner hole workpiece machining clamp adopting the technical scheme has the beneficial effect that the clamping effect is good, the structure is simple, and operation is convenient.
Description
technical field [0001] The invention relates to the technical field of clamping devices, in particular to a clamp for processing inner hole workpieces. Background technique [0002] During the machining process, it is necessary to locate and lock the parts to be processed. The positioning is used to ensure the accuracy of the machining, and the locking can prevent the parts from flying out during the machining process and prevent accidents. Existing fixtures are usually composed of positioning elements, clamping devices, tool setting guide elements, indexing devices, connecting elements, and clamp bodies, etc., which have the problems of complex structure, poor clamping effect and difficult fabrication. Contents of the invention [0003] The object of the present invention is to solve the above technical problems, and provide a fixture for processing inner hole workpieces, which has the characteristics of good clamping effect, simple structure and convenient operation. ...
