Abstract
Description
Technical Field
[0001] This utility model relates to the field of workbenches, and in particular to an EDM workbench for mold processing. Background Technology
[0002] An electrical discharge machine (EDM) is a special processing equipment that uses the electro-erosion effect generated by pulse discharge between two electrodes immersed in a working fluid to remove conductive materials. The EDM machine generates an instantaneous high temperature, high pressure, and high speed oxidation reaction on the surface of the workpiece through the discharge of high voltage electronic pulses, which instantly vaporizes the surface of the workpiece to form tiny pits, thereby realizing the processing of metal materials.
[0003] The worktable of an EDM machine is a crucial component of the EDM system. It supports and holds the workpiece, ensuring the stability and precision of the machining process. An EDM machine worktable typically consists of the following parts: Base: Serving as the supporting structure for the entire worktable, it must be robust and stable, capable of withstanding various forces and vibrations during machining; Worktable Surface: The part that directly contacts the workpiece, usually made of wear-resistant and corrosion-resistant materials, such as cemented carbide, ceramics, or specially treated metals. The worktable surface needs to be flat to ensure the accuracy of workpiece machining; Positioning Device: Used for precise positioning and clamping of the workpiece to ensure it does not move or deform during machining. This includes various fixtures, suction cups, pressure plates, etc.
[0004] In existing EDM worktables, the positioning device is usually manually operated to clamp the parts. This operation is complex and requires constant adjustment during clamping, making the clamping process cumbersome. Utility Model Content

[0006] The technical solution adopted by this utility model to solve its technical problem is:
[0007] An EDM worktable for mold processing includes a base, a support plate and a clamping assembly on the base. The support plate is used to place the part to be processed, and the clamping assembly is used to clamp the part to be processed. The bottom surface of the base is provided with a mounting base plate for assembly with the EDM machine. The base is provided with an upward-opening drive cavity, and the clamping assembly is disposed in the drive cavity. The side wall of the support plate is provided with two opposing through slots. The support plate covers the opening of the base, and the clamping assembly extends through the through slots to the top of the support plate.
[0008] The clamping assembly includes a fixed clamping plate, a movable clamping plate, a fixed mounting base, and a drive cylinder. The fixed clamping plate is mounted on the fixed mounting base, which has a sliding groove and a fixing screw. The side wall of the sliding groove and the inner wall of the sliding groove slide against each other. The base has a positioning groove, and the fixing screw can pass through the fixed mounting base and be inserted into the positioning groove on the surface of the support plate. The drive cylinder is located in the drive cavity, and the extension rod of the drive cylinder is parallel to the surface of the support plate. The movable clamping plate has a connecting bracket, which passes through the sliding groove and connects to the extension rod of the drive cylinder.
[0009] Furthermore, the connecting bracket is provided with a positioning groove, and the side wall of the through groove and the inner wall of the positioning groove slide against each other. When the driving cylinder drives the connecting bracket, the connecting bracket slides along the through groove through the positioning groove.
[0010] Furthermore, both the connecting bracket and the fixed mounting base are provided with positioning holes, and the fixed clamping plate and the movable clamping plate are detachably connected to the connecting bracket and the fixed mounting base respectively by mounting bolts.
[0011] Furthermore, the fixed clamping plate and the movable clamping plate are provided with accessory holes and positioning pin holes for installing irregular clamps, and positioning pins on irregular clamps can be inserted into the positioning pin holes.
[0012] Furthermore, the base has a baffle edge made of dark acrylic sheet. The baffle edge reduces the brightness of sparks observed during processing. A door panel is provided on the baffle edge to facilitate the placement of parts. The door panel is connected to the baffle edge by a hinge.
[0013] Furthermore, the lower end of the base is provided with a horizontally movable slide, and the base plate for assembly with the EDM machine is installed at the lower end of the slide.
[0014] Compared with existing technologies, the advantages of this invention are: by driving a cylinder to move the movable clamping plate closer to the fixed clamping plate, the part is clamped. This method is simple to use. Simultaneously, the fixed clamping plate can be adjusted in position on the support plate to accommodate parts of different sizes.

[0022] The following is combined Figures 1-5 This utility model provides a detailed description of an EDM worktable for mold processing:
[0023] An EDM worktable for mold processing includes a base 1, a support plate 2 and a clamping assembly on the base 1. The support plate 2 is used to place the part to be processed, and the clamping assembly is used to clamp the part to be processed. The bottom surface of the base 1 is provided with a mounting base plate for assembly with the EDM machine. The base 1 is provided with an upward-opening drive cavity 3, and the clamping assembly is disposed in the drive cavity 3. The side wall of the support plate 2 is provided with two opposing through slots 4, the support plate 2 covering the opening of the base 1. The clamping assembly extends through the through slots 4 to the top of the support plate 2. The lower end of the base 1 is provided with a horizontally movable slide for connecting with the EDM machine. The base plate of the EDM machine assembly is installed at the lower end of the slide table. The slide table can move laterally and longitudinally, allowing the base 1 to be moved left and right on the EDM machine for position adjustment, improving the flexibility and convenience of part processing, avoiding the need to move the clamped parts again, ensuring the stability of the clamped parts, and improving the processing efficiency of the parts. The edge of the base 1 is provided with a guard 5, which is made of dark acrylic plate. The guard 5 reduces the brightness of the sparks observed during processing, effectively protecting the operator's eyesight. The guard 5 is provided with a door panel 6 for easy placement of parts, and the door panel 6 is connected to the guard 5 by a hinge.
[0024] The clamping assembly includes a fixed clamping plate 7, a movable clamping plate 8, a fixed mounting base 9, and a drive cylinder 10. The fixed clamping plate 7 is mounted on the fixed mounting base 9, which has a sliding groove and a fixing screw 11. The side wall of the through groove 4 and the inner wall of the sliding groove slide against each other. The base 1 has a positioning groove 12. The fixing screw 11 can pass through the fixed mounting base 9 and be inserted into the positioning groove 12 on the surface of the support plate 2. The fixed clamping plate 7 can also be adjusted on the support plate 2 to accommodate parts of different sizes. The drive cylinder 10 is mounted on the drive... Inside cavity 3, the telescopic rod of drive cylinder 10 is parallel to the surface of support plate 2. A connecting bracket 13 is provided on movable clamping plate 8.

The side wall of through groove 4 and the inner wall of positioning groove 12 slide against each other. When drive cylinder 10 drives connecting bracket 13, connecting bracket 13 slides along through groove 4 through positioning groove 12, ensuring that connecting bracket 13 remains stable when sliding and reducing the vibration generated when connecting bracket 13 slides.
[0025] Both the connecting bracket 13 and the fixed mounting base 9 are provided with positioning holes. The fixed clamping plate 7 and the movable clamping plate 8 are detachably connected to the connecting bracket 13 and the fixed mounting base 9 respectively by mounting bolts.
