Embodiment 1
[0034] A vise that uses parallel arms to achieve clamping of odd-shaped workpieces, such as Figure 1-6 As shown, it includes vise frame one 1, mounting block one 101, universal shaft sleeve one 102, anti-skid pad one 103, bearing nut 1011, vise frame two 2, anti-skid pad one 103, bearing nut 1011, vise frame 2. Installation block 2 201, universal shaft sleeve 2 202, anti-slip pad 2 203, screw 1 3, handle 301 and guide rod 4, the vise frame is divided into two, namely vise frame 1 and vise frame 2. The vise frame 1 is located in front of the vise frame 2. The installation block 101 is rotatably connected to the middle of the vise frame 1. There are two universal bushings 102, and the universal bushing 102 is symmetrically fixed on the On the left and right sides of vise frame one 1, the anti-slip pad one 103 is fixed on the rear side of vise frame one 1 by screws, the bearing nut 1011 is rotatably connected to the installation block one 101, and vise frame two 2 is located beh...
Embodiment 2
[0037] On the basis of Example 1, such as Figure 6 As shown, it also includes L-shaped frame 5, screw rod 2 6 and pressure pad 7, L-shaped frame 5 is fixedly connected to the top of vise frame 2 2, screw rod 2 6 is threadedly connected to L-shaped frame 5, and pressure pad 7 is rotatably connected to Screw rod two 6 below.
[0038] When clamping a special-shaped workpiece, the L-shaped frame 5 is manually fixed on the workbench by screwing the screw 2 6, so that the pressure pad 7 is in contact with the workbench, so that the overall vise is firmly and stably clamped on the workbench, realizing Function of the fixed vise.

Abstract
The invention relates to a vise for clamping, in particular to a vise for clamping special-shaped workpieces by using parallel arms. Provided is a vise capable of firmly fixing special-shaped workpieces, which uses parallel arms to realize clamping of special-shaped workpieces. The technical solution of the present invention provides a vise that uses parallel arms to clamp special-shaped workpieces, including vise frame 1, mounting block 1, Vientiane bushing 1, anti-slip pad 1, bearing nuts, vise frame 2, and anti-slip pad 1 , Bearing nut, vise frame 2, mounting block 2, Vientiane bushing 2, anti-skid pad 2, screw rod 1, handle and guide rod, the vise frame is divided into two, respectively vise frame 1 and vise frame 2, The vise frame one is located in front of the vise frame two, the mounting block one is connected to the middle part of the vise frame one by rotation, the Vientiane bushing is two, and the Vientiane bushing is symmetrically fixed on the left and right sides of the vise frame one, the present invention can Accurately fix the processing position of the parts, the design structure is concise and compact, and it is easy to operate.
Description
technical field [0001] The invention relates to a vise for clamping, in particular to a vise for clamping special-shaped workpieces by using parallel arms. Background technique [0002] The vise is a universal fixture used to clamp the workpiece. It is installed on the workbench to clamp the workpiece stably. It is an essential tool for the fitter workshop. Machine vise features: simple and compact design structure, strong clamping force, easy to operate and use. The inner nut is generally made of stronger metal material to keep the clamping force greater. Fixtures are an indispensable part of mechanical processing, which can accurately fix the processing position of parts, reduce the labor intensity of workers, and improve labor efficiency. At present, common fixtures are used for a single purpose, one kind of fixture is used to fix a workpiece of one shape, or one kind of fixture is used to fix workpieces of various specifications and shapes. For some special-shaped wor...
