Description

Technical Field

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

[0002] Wire EDM is short for wire cutting, referring to a machining method. It was developed based on electrical discharge machining (EDM) for drilling and forming. It uses a moving metal wire (molybdenum wire, copper wire, or alloy wire) as an electrode wire. The pulsed electric spark discharge between the electrode wire and the workpiece generates high temperature, which melts or vaporizes the metal, forming a kerf, thereby cutting out the part.

[0003] Wire EDM requires the use of a fixture to hold the workpiece in place. However, current wire EDM fixtures, once fixed to the machine, cannot adjust the initial position of the workpiece, resulting in low flexibility. Secondly, after the workpiece is secured, the bolts used to lock the clamping components must be loosened before rotating the workpiece to adjust the angle, and then the bolts tightened again. This adjustment method relies entirely on the operator's skill to control the accuracy, making it neither simple nor convenient, and not user-friendly for beginners. Therefore, to address these shortcomings, this invention proposes a new wire EDM fixture. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wire cutting fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wire cutting fixture, comprising a housing and a mounting plate, wherein a telescopic component is connected between the lower surface of the housing and the upper surface of the mounting plate, a horizontal shaft is rotatably connected through the middle of the housing via a bearing, both ends of the horizontal shaft are located outside the housing, and end plates and a scale are respectively fixedly connected to both ends of the horizontal shaft, a clamping component is provided on the side of the end plate away from the horizontal shaft, an adjustment component for driving the horizontal shaft to rotate is provided inside the housing, and a pointer is fixed on the outer wall of the housing above the scale.

[0006] Furthermore, the clamping assembly includes a first clamping plate and a side plate fixed to both sides of the end plate. A screw is threaded through the middle of the side plate and connected to it. A second clamping plate is rotatably connected to one end of the screw near the first clamping plate via a bearing. A nut is fixed to the other end of the screw.

[0007] Furthermore, a guide rod is fixedly connected between the first clamping plate and the side plate, and the guide rod passes through the second clamping plate and is slidably connected to the second clamping plate.

[0008] Furthermore, slots are provided on the adjacent sides of the first and second clamping plates and at the ends away from the end plates.

[0009] Furthermore, the adjustment assembly includes a worm gear fixed to the surface of the horizontal shaft and a vertical shaft penetrating the top wall of the housing. The vertical shaft is rotatably connected to the top wall of the housing via a bearing. A worm is fixedly connected to one end of the vertical shaft inside the housing, and the worm meshes with the worm gear. A nut is fixedly connected to one end of the vertical shaft outside the housing.

[0010] Furthermore, the telescopic assembly includes a fixing plate fixed to the upper surface of the mounting plate and a shell plate fixed to the lower surface of the housing. The shell plate has a hollow interior and an open end away from the housing. The fixing plate is located inside the shell plate and is slidably connected to the shell plate at the end away from the mounting plate. The top wall of the shell plate is threaded with a locking bolt.

[0011] Furthermore, one side of the housing is designed to be open, and a side cover is fixedly connected to the open side of the housing by screws.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, this utility model provides a wire EDM fixture comprising a housing, a horizontal axis, an end plate, a clamping assembly, an adjusting assembly, a dial, and a pointer. After the workpiece is clamped by the clamping assembly, the horizontal axis, end plate, and clamping assembly can be rotated by the driving assembly. This allows for direct adjustment of the workpiece angle after it is clamped. The dial, which is fixedly connected to the horizontal axis, also rotates synchronously. With the pointer pointing to the position of the dial, the workpiece rotation angle can be determined more accurately, making the workpiece processing more flexible and convenient.

[0014] 2. In use, this utility model provides a wire cutting fixture with a housing, a telescopic component, and a mounting plate. After the fixture is fixed by the mounting plate, the position of the housing can be adjusted by the telescopic component, thereby flexibly adjusting the initial position of the clamped workpiece during processing and improving the convenience of processing.

Detailed Implementation

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1-3 As shown, a wire cutting fixture is disclosed, comprising a housing 1 and a mounting plate 3. A telescopic component 2 is connected between the lower surface of the housing 1 and the upper surface of the mounting plate 3. A horizontal shaft 4 is rotatably connected through the middle of the housing 1 via a bearing. Both ends of the horizontal shaft 4 are located outside the housing 1, and end plates 5 and dials 8 are fixedly connected to both ends of the horizontal shaft 4, respectively. A clamping component 6 is provided on the side of the end plate 5 away from the horizontal shaft 4. An adjusting component 7 for driving the horizontal shaft 4 to rotate is provided inside the housing 1. A pointer 9 is fixed on the outer wall of the housing 1 above the dial 8.

[0023] The clamping assembly 6 includes a first clamping plate 61 and a side plate 62 fixed to both sides of the end plate 5. A screw 63 is threaded through the middle of the side plate 62. A second clamping plate 64 is rotatably connected to one end of the screw 63 near the first clamping plate 61 via a bearing. A nut is fixed to the other end of the screw 63.

[0024] After placing the workpiece to be cut between the first clamping plate 61 and the second clamping plate 64, the screw 63 can be turned with a wrench to move the second clamping plate 64 closer to the first clamping plate 61, and the workpiece can be clamped and fixed by the first clamping plate 61 and the second clamping plate 64.

[0025] A guide rod 66 is fixedly connected between the first clamping plate 61 and the side plate 62. The guide rod 66 passes through the second clamping plate 64 and is slidably connected to the second clamping plate 64.

[0026] The guide rod 66 can prevent the second clamping plate 64 from rotating during movement, thus playing a role in stabilizing the guide.

[0027] Both the first clamping plate 61 and the second clamping plate 64 have slots 65 on their adjacent sides and at the ends away from the end plate 5.

[0028] When using the first clamping plate 61 and the second clamping plate 64 to clamp the workpiece, the workpiece can be stuck inside the slot 65, thereby minimizing the contact area between the first clamping plate 61 and the second clamping plate 64 and the workpiece, and avoiding affecting the cutting.

[0029] The adjusting assembly 7 includes a worm gear 71 fixed to the surface of the horizontal shaft 4 and a vertical shaft 72 penetrating the top wall of the housing 1. The vertical shaft 72 is rotatably connected to the top wall of the housing 1 through a bearing. A worm 73 is fixedly connected to one end of the vertical shaft 72 inside the housing 1. The worm 73 meshes with the worm gear 71. A nut is fixedly connected to one end of the vertical shaft 72 outside the housing 1.

[0030] After the vertical shaft 72 is rotated outside the housing 1 with a wrench, the worm 73 drives the worm wheel 71 to rotate, which in turn drives the horizontal shaft 4 to rotate, thereby driving the end plate 5 and the dial 8 to rotate synchronously. Since the worm 73 and the worm wheel 71 have self-locking properties, they can be fixed after rotating to any angle.

[0031] The telescopic assembly 2 includes a fixing plate 22 fixed to the upper surface of the mounting plate 3 and a shell plate 21 fixed to the lower surface of the housing 1. The shell plate 21 has a hollow interior and an open end away from the housing 1. The fixing plate 22 is located inside the shell plate 21 and is slidably connected to the shell plate 21 at the end away from the mounting plate 3. The top wall of the shell plate 21 is threaded with a locking bolt 23.

[0032] When it is necessary to adjust the initial position of the workpiece held by the first clamping plate 61 and the second clamping plate 64, the shell plate 21 can be moved along the fixing plate 22, and then the locking bolt 23 can be tightened to fix the shell plate 21.

[0033] One side of the housing 1 is open, and a side cover is fixedly connected to the open side of the housing 1 by screws. By opening the side cover, oil can be injected into the worm 73 and worm wheel 71 to improve their service life.

[0034] Working principle: First, align the threaded holes on the mounting plate 3 with the mounting holes on the wire cutting machine, then tighten bolts into the holes to fix the mounting plate 3. During cutting, place the workpiece between the first clamping plate 61 and the second clamping plate 64, then rotate the screw 63 to move the second clamping plate 64, thereby using the first clamping plate 61 and the second clamping plate 64 to clamp and fix the workpiece. When it is necessary to adjust the initial position of the workpiece, first loosen the locking bolt 23 and then move the shell plate 21. After adjustment, tighten the locking bolt 23. If it is necessary to change the angle of the workpiece, turn the nut at the top of the vertical shaft 72 to rotate the end plate 5 and the clamping assembly 6. During the rotation, observe the position of the scale 8 indicated by the pointer 9, which is the angle of rotation of the clamping assembly 6 and the workpiece, so as to more accurately know the angle of rotation of the workpiece.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, numerous modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
