It uses a moving metal wire (molybdenum wire, copper wire or alloy wire) as an electrode wire, and relies on pulsed electric spark discharge between the electrode wire and the workpiece to generate high temperature to melt or vaporize the metal, forming a slit, thereby cutting out the parts. The transmission between the gear and the rack is used to drive the fixed blocks on both sides to clamp the workpiece, but due to the long-term meshing process of the gear and the rack, noise and vibration will be generated, which will affect the stability of the entire cutting machine.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a workpiece clamping fixture for a wire cutting machine tool, comprising a mounting plate 1, a rotating mechanism 2 for adjusting the angle of a workpiece is arranged on the top of the mounting plate 1, a clamping mechanism 3 for fixing the workpiece is arranged on the top of the rotating mechanism 2, a first tooth plate 22 and a second tooth plate 28 in the rotating mechanism 2 are clamped, a support plate 21 is fixedly installed on the top of the rotating mechanism 2, an inner side wall of the support plate 21 is rotatably connected with a shaft tube 23, and a bracket 24 is fixedly installed on the outer side of the shaft tube 23;

[0024] A spring 25 and a telescopic rod 26 are fixedly installed inside the shaft tube 23 , a connecting seat 27 is fixedly installed at the ends of the spring 25 and the telescopic rod 26 , and a pulling block 29 is rotatably connected to the outer end of the connecting seat 27 .

[0025] The advantage of adjusting the workpiece angle as required is achieved, so that the cutting surface of the workpiece can be at a required angle during cutting.

[0026] The spring 25 is located outside the telescopic rod 26, and a pull ring is fixedly installed on the outer end of the pulling block 29. The setting of the pull ring is conducive to pulling the pulling block 29 and the components connected thereto to move outward.

[0027] In addition, the first tooth plate 22 is fixedly mounted on the outer side of the support plate 21 , and the second tooth plate 28 is fixedly mounted on the inner end of the connecting seat 27 , which facilitates the support and installation of the first tooth plate 22 and the second tooth plate 28 .

[0028] The state shown in the figure is a fixed state:

[0029] When adjustment is required, the pull ring is pulled outward, and the pull ring drives the pull block 29 to move outward. At this time, the pull block 29 drives the connecting seat 27 to move outward and detach from the outside of the shaft tube 23, so as to stretch the spring 25 and the telescopic rod 26. In addition, during the stretching process, the connecting seat 27 drives the second tooth plate 28 to move, and the second tooth plate 28 and the first tooth plate 22 are detached from the clamping state, so that the adjustment work can be carried out.

[0030] After the above operation, the bracket 24 can be directly rotated. At this time, the bracket 24 directly drives the shaft tube 23 to rotate, and the shaft tube 23 drives the second tooth plate 28 to rotate together through the spring 25, the telescopic rod 26 and the connecting seat 27, and the clamping mechanism 3 on the top and the workpiece clamped on the inner side will be driven to rotate at the same time, so as to rotate and adjust to the required angle. After the adjustment is completed, the pulling force can be released. At this time, the spring 25 causes the first tooth plate 22 and the second tooth plate 28 to form a clamping state again according to the contraction force of the elastic force, so as to complete the angle adjustment operation.

[0031] The adjustment process can be repeated according to the above method to adjust to the required angle position, and then the processing operation can be carried out.

[0032] Preferably, the clamping mechanism 3 includes a connecting frame 31 , a pushing assembly and a sliding assembly. The connecting frame 31 is fixedly mounted on the inner end of the bracket 24 , the pushing assembly is arranged on the inner side of the connecting frame 31 , and the sliding assembly is arranged on the inner side of the connecting frame 31 .

[0033] like Figure 3 As shown, the pushing assembly includes a threaded hole, which is opened on the outer side of the connecting frame 31. The inner thread of the threaded hole is connected to a threaded rod 32. The inner end of the threaded rod 32 is rotatably connected to a clamping plate 33 for laterally clamping and fixing the workpiece.

[0034] like Figure 3 As shown, the sliding assembly includes a connecting block 34, which is fixedly mounted on the outer end of the clamping plate 33. A sliding hole 35 is opened on the outer side of the connecting frame 31 to facilitate supporting the clamping plate 33 and enabling it to slide stably and limit its position during the sliding process.

[0035] In addition, the connecting block 34 is slidably connected to the inside of the sliding hole 35, and a wire hole is opened in the middle of the side of the connecting frame 31, which can facilitate the passing of the cutting line during the installation process, thereby assisting the cutting work and facilitating the disassembly and assembly of the entire set of tooling.

[0036] When clamping the workpiece:

[0037] The threaded rod 32 is directly rotated clockwise, and the threaded connection between the threaded rod 32 and the threaded hole facilitates the direct push of the two sets of clamping plates 33 to move inwards. At this time, after being in a suitable position, the workpiece is directly placed inside the two sets of clamping plates 33, and the two sets of clamping plates 33 are continuously pushed inwards according to the above-mentioned rotation method until the workpiece is clamped and fixed;

[0038] When the splint 33 is pushed, the connecting block 34 will move together. At this time, the connecting block 34 will slide inside the sliding hole 35. The sliding of the two can support the splint 33 and assist its stability when sliding, and limit its position based on the assistance.

[0039] During operation, the workpiece can be fixed first as required, and then the angle of the workpiece can be adjusted, and then the cutting operation can be carried out.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
