Special-shaped workpiece auxiliary clamp

Abstract

The special-shaped workpiece auxiliary clamp comprises a bottom plate, a threaded rod is arranged on the side edge of a motor, sliding blocks are arranged at the left end and the right end of the outer portion of the threaded rod in a sleeved mode, a rotating ring is arranged on the lower portion of an air cylinder, a fixing plate is arranged on the lower portion of the rotating ring, fixing blocks are arranged at the left end and the right end of the fixing plate, and chucks are assembled on the lower portions of the fixing blocks. And an anti-skid pad is assembled on the inner side of the chuck. According to the special-shaped workpiece auxiliary clamp, the position and the angle of the chuck can be conveniently adjusted according to the shape of a workpiece through sliding of the sliding block and rotation of the rotating ring, meanwhile, the stability of the workpiece is enhanced by arranging an anti-skid pad in the chuck, and the situation that when the chuck clamps and fixes the workpiece, due to the irregular shape of the workpiece, the workpiece cannot be damaged is avoided. According to the special-shaped workpiece clamping device, due to the fact that the clamping head is arranged, a workpiece is prone to falling off from the clamping head in the workpiece clamping process, the device cannot effectively fix the workpiece, and then the fixing stability of the special-shaped workpiece is greatly improved, and the machining accuracy of the special-shaped workpiece is improved.

Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an auxiliary clamp for special-shaped workpieces. Background Art

[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process in the process can be called a fixture, such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc.

[0003] There are many types of existing clamps, but the types of parts are even more numerous. For example, irregular polygonal parts with bumps or grooves, the existing ordinary clamps cannot fix such parts well, and will cause deviation when the parts are processed. When the chuck clamps the workpiece, due to the irregular shape of the workpiece, the workpiece is easy to fall out of the chuck during the clamping process, resulting in the device being unable to effectively fix the workpiece, thereby reducing the processing efficiency of the parts and even affecting the service life of the finished product. In addition, it cannot be adjusted according to the size of the workpiece, thereby reducing the use effect of the device. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, the present application aims to provide an auxiliary clamp for special-shaped workpieces, comprising a base plate, support rods are provided at the left and right ends of the upper part of the base plate, a top plate is provided on the side of the support rod, a motor is provided on the left side of the top plate, a threaded rod is provided on the side of the motor, sliders are provided on the left and right ends of the outer side of the threaded rod, a cylinder is provided at the lower part of the slider, a rotating ring is provided at the lower part of the cylinder, a fixed plate is provided at the lower part of the rotating ring, fixed blocks are provided at the left and right ends of the fixed plate, a chuck is mounted at the lower part of the fixed block, and an anti-slip pad is mounted on the inner side of the chuck.

[0005] Preferably, the support rods are symmetrically mounted on the left and right ends above the bottom plate, and the top plate is fixedly mounted on one side of the support rods.

[0006] Preferably, the motor is mounted on one end of the top plate, the threaded rod is threadedly connected to one side of the motor, and the slider is symmetrically mounted on the outer wall of the threaded rod.

[0007] Preferably, the cylinder is installed below the slider, the rotating ring is movably installed below the cylinder, the fixed plate is symmetrically installed below the rotating ring, and the fixed blocks are symmetrically installed at left and right ends of the fixed plate.

[0008] Preferably, the chuck is movably mounted on the lower end of the fixed block, and the anti-slip pad is mounted on one side of the chuck.

[0009] Beneficial effects:

[0010] The auxiliary clamp for special-shaped workpieces, when processing the workpiece, drives two groups of slide blocks on the threaded rod to move through a motor, so that the position between the chuck and the workpiece is adjusted according to the movement of the slide block, and when the position of the chuck is adjusted, the cylinder drives the chuck to move downward, and adjusts the height of the chuck according to the size of the workpiece, so that the chuck can better clamp and fix the special-shaped workpiece. Since the special-shaped workpiece has different irregular shapes, it is necessary to adjust the position of the chuck according to the size of the workpiece and the angle of the workpiece when clamping the workpiece. At this time, the sliding of the slide block and the rotation of the rotating ring make it easy for the chuck to adjust the position and angle of the chuck according to the shape of the workpiece. At the same time, the anti-slip pad provided in the chuck enhances the stability of the workpiece, and prevents the chuck from easily falling off the chuck during the clamping process of the workpiece due to the irregular shape of the workpiece when clamping the workpiece, resulting in the device being unable to effectively fix the workpiece, thereby greatly improving the stability of the fixation of the special-shaped workpiece and improving the accuracy of processing the special-shaped workpiece.

[0019] The support rods 2 are symmetrically installed on the left and right ends above the bottom plate 1 , and the top plate 3 is fixedly installed on one side of the support rods 2 .

[0020] The motor 4 is installed at one end of the top plate 3 , the threaded rod 401 is threadedly connected to one side of the motor 4 , and the slider 5 is symmetrically installed on the outer wall of the threaded rod 401 .

[0021] The cylinder 6 is installed below the slider 5 , the rotating ring 7 is movably installed below the cylinder 6 , the fixed plate 8 is symmetrically installed below the rotating ring 7 , and the fixed blocks 9 are symmetrically installed at the left and right ends of the fixed plate 8 .

[0022] The clamp 10 is movably mounted on the lower end of the fixed block 9 , and the anti-slip pad 11 is mounted on one side of the clamp 10 .

[0023] When in use, when processing a workpiece, the motor 4 drives the two sets of sliders 5 on the threaded rod 401 to move, so that the chuck 10 is adjusted in position with the workpiece according to the movement of the slider 5. When the position of the chuck 10 is adjusted, the cylinder 6 drives the chuck 10 to move downward, and adjusts the height of the chuck 10 according to the size of the workpiece, so that the chuck 10 can better clamp and fix the special-shaped workpiece. Since the special-shaped workpiece has different irregular shapes, it is necessary to adjust according to the size of the workpiece and the angle of the workpiece when clamping the workpiece. The position of the chuck 10 is adjusted by sliding the slider 5 and rotating the rotating ring 7 according to the shape of the workpiece. At the same time, the anti-slip pad 11 provided in the chuck 10 can enhance the stability of the workpiece and prevent the chuck 10 from falling off the chuck 10 due to the irregular shape of the workpiece during the clamping process, thereby making it impossible for the device to effectively fix the workpiece. This greatly improves the stability of the fixation of special-shaped workpieces and improves the accuracy of processing special-shaped workpieces.
