Description

Technical Field

[0001] This utility model relates to a clamping tool, and more particularly to a general-purpose clamping tool. Background Technology

[0002] In wire EDM and EDM processes, the workpiece clamping accuracy plays a crucial role in machining accuracy. However, existing fixtures have the following shortcomings:

[0003] 1. Due to the wide variety of shapes and complex structures of the parts being processed, wire EDM is required for corner clearing. Therefore, the original fixtures must be disassembled before processing, which necessitates manual repositioning and adjustment, affecting processing efficiency. This is particularly disadvantageous in automated production processes.

[0004] 2. Poor usability: A single fixture is often only suitable for workpieces of a specific shape and size. Different fixtures need to be changed for clamping different types of workpieces, which increases processing costs and preparation time. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a universal clamping tool that can achieve rapid and repeated positioning and is applicable to workpieces of different sizes and shapes.

[0006] The technical solution of this utility model is as follows: A general-purpose clamping tool includes a base and a mounting base. The mounting base is disposed on the base and detachably connected to the base. The upper end face of the mounting base is provided with a first sliding groove group and a second sliding groove group. The first sliding groove group includes two parallel first sliding grooves arranged along the length direction of the mounting base. The second sliding groove group includes two parallel second sliding grooves arranged along the width direction of the mounting base. The first and second sliding grooves are interconnected. The mounting base is provided with four detachable sliders. Each slider slides on the mounting base to clamp or release the workpiece. The lower end face of each slider is provided with a protrusion. When each protrusion slides in the first sliding groove, the distance between two adjacent sliders in the length direction can be adjusted. When each slider slides in the second sliding groove, the distance between two adjacent sliders in the width direction can be adjusted.

[0007] By adopting the above technical solution, the distance between the sliders can be adjusted by sliding the sliders to adapt to workpieces of different sizes and shapes. The sliders are detachable and their positions can be changed, allowing them to slide from the first slide groove to the second slide groove, and from clamping workpieces of different lengths to clamping workpieces of different widths. This allows for quick adaptation to workpieces of different shapes and sizes, making it highly versatile. The base is fixedly installed on the machine tool table or head, and the mounting base is detachable from the base. When multiple clamping tools are performing different processes simultaneously, the mounting bases can be interchanged without disassembly and repetitive positioning and correction steps, thus improving machining accuracy and efficiency.

[0008] A further feature of this invention is that each slider is provided with a clamping block and a first driving member connected to the clamping block. Each slider is provided with an installation groove. The clamping block is located in the corresponding installation groove. One end of the first driving member is located outside the slider, and the other end extends into the installation groove and is connected to the clamping block, so as to drive the clamping block to slide in the installation groove and extend or retract the slider.

[0009] With the above further configuration, the first driving component is set with a screw. By rotating the screw, the clamping block slides in the mounting groove and slides out or retracts from the mounting groove. When the clamping block slides out, it can clamp the workpiece, making the workpiece structure stable and not easy to slip during processing. The surface of the clamping component is provided with an anti-slip and wear-resistant layer, which can provide sufficient clamping force when clamping the workpiece, while preventing the workpiece surface from being damaged.

[0010] A further feature of this invention is that the mounting groove has guide grooves on both sides of the side wall along the sliding direction of the clamping block, and the clamping block has guide blocks on its side wall, with the guide blocks slidably disposed in the guide grooves.

[0011] The above-mentioned further design makes the structure more stable and the positioning accuracy higher when the clamping block slides.

[0012] A further feature of this invention is that the base is provided with a plurality of positioning blocks, and the mounting seat is provided with a corresponding first positioning groove. The positioning blocks are inserted into the corresponding first positioning groove to achieve the connection between the mounting seat and the base.

[0013] By adopting the above-mentioned further settings, rapid and accurate positioning can be achieved, making disassembly and assembly easier.

[0014] A further feature of this invention is that positioning clips extending in opposite directions are provided on both sides of the lower end face of the positioning groove. When the mounting base is connected to the base, the ends of the positioning clips abut against the side wall of the positioning block.

[0015] The above-mentioned further design makes the structure more stable after the mounting base and the base are installed.

[0016] A further feature of this invention is as follows: the mounting base is provided with diagonally arranged connectors, and the base is provided with mounting holes for inserting the ends of the connectors. The connectors located in the mounting holes are provided with second positioning grooves. The base is provided with a sliding seat and positioning rods located on both sides of the sliding seat. The positioning rods are located between the connectors and the sliding seat. The sliding seat is connected to a second driving member that drives it to slide. The second driving member is partially located outside the base. The positioning rods slide synchronously with the sliding seat so that the ends of the positioning rods extend into or disengage from the second positioning grooves.

[0017] With the above-mentioned further configuration, the sliding seat is driven by the second driving component to move the positioning rod towards the connecting component. The end of the positioning rod is inserted into the second positioning groove, which can limit the mounting seat. The cooperation between the positioning rod and the positioning groove, as well as the cooperation between the second positioning groove and the positioning block, can accurately limit the mounting seat in the X, Y, and Z directions. When the sliding seat slides in the reverse direction, the positioning rod disengages from the positioning groove. At this time, the mounting seat can be removed from the base. The disassembly and assembly are convenient and quick, shortening the workpiece clamping time and improving processing efficiency.

[0018] A further improvement of this invention is that: both sides of the sliding seat are provided with inclined connecting grooves, and the positioning rod is provided with a corresponding connecting block. The connecting block is located in the connecting groove so as to drive the positioning rod to slide when the sliding seat slides.

[0019] By adopting the above-mentioned further settings, the movement of the positioning rod is better driven, making the structure stable when it slides. Attached Figure Description

[0036] like Figure 1-11As shown, a general-purpose clamping tool includes a base 1 and a mounting base 2. The mounting base 2 is disposed on the base 1 and detachably connected to the base 1. The upper surface of the mounting base 2 is provided with a first set of sliding grooves 21 and a second set of sliding grooves 22. The first set of sliding grooves 21 includes two parallel first sliding grooves 21 arranged along the length direction of the mounting base 2. The second set of sliding grooves 22 includes two parallel second sliding grooves 22 arranged along the width direction of the mounting base 2. The first sliding grooves 21 and the second sliding grooves 22 are interconnected. The mounting base 2 is provided with four detachable sliders 3. Each slider 3 slides on the mounting base 2 to clamp or release workpieces. The lower surface of each slider 3 is provided with a protrusion 31. When each protrusion 31 slides in the first sliding groove 21, the distance between two adjacent sliders 3 in the length direction can be adjusted. When each slider 3 slides in the second sliding groove 22, the distance between two adjacent sliders 3 in the width direction can be adjusted. Figure 4 The direction indicated by line a is the length direction, and the direction indicated by line b is the width direction. The spacing between sliders 3 can be adjusted by sliding slider 3 to adapt to workpieces of different sizes and shapes. Slider 3 is detachable and its position can be changed, so that it slides from the first slide groove 21 to the second slide groove 22, and can be used to clamp workpieces of different lengths to clamp workpieces of different widths. It can quickly adapt to workpieces of different shapes and sizes, and has strong versatility. The base 1 is fixedly installed on the machine tool worktable or machine head. The mounting seat 2 is detachable from the base 1. When multiple clamping tools are performing different processes simultaneously, the mounting seats 2 can be interchanged without disassembly and repetitive positioning and correction steps, thus improving processing accuracy and efficiency.

[0037] Each slider 3 is equipped with a clamping block 32 and a first driving member 33 connected to the clamping block 32. Each slider 3 has a mounting groove 34. The clamping block 32 is located in the corresponding mounting groove 34. One end of the first driving member 33 is located outside the slider 3, and the other end extends into the mounting groove 34 and is connected to the clamping block 32 to drive the clamping block 32 to slide in the mounting groove 34 and extend or retract from the slider 3. The first driving member 33 is a screw. By rotating the screw, the clamping block 32 slides in the mounting groove 34 and moves towards the mounting groove 34. 4. When the clamping block 32 slides out, it can clamp the workpiece, making the workpiece structure stable and preventing it from slipping during processing. The surface of the clamping part is provided with an anti-slip and wear-resistant layer, which can provide sufficient clamping force when clamping the workpiece and prevent the workpiece surface from being damaged. The mounting groove 34 is provided with guide grooves 341 on both sides of the clamping block 32 along the sliding direction. The side wall of the clamping block 32 is provided with guide blocks 321. The guide blocks 321 are slidably disposed in the guide grooves 341, making the structure of the clamping block 32 more stable and the positioning accuracy higher when it slides.

[0038] The base 1 is provided with a plurality of positioning blocks 11, and the mounting seat 2 is provided with a corresponding first positioning groove 23. The positioning blocks 11 are inserted into the corresponding first positioning groove 23 to realize the connection between the mounting seat 2 and the base 1. The two sides of the lower end face of the first positioning groove 23 are provided with positioning clips 231 extending towards each other. When the mounting seat 2 is connected to the base 1, the end of the positioning clip 231 abuts against the side wall of the positioning block 11, making the structure of the mounting seat 2 and the base 1 more stable after installation, enabling fast and accurate positioning and facilitating disassembly and assembly.
