[0002] The linear guide slider drilling fixture is a tool specially used for precise drilling on the linear guide slider. It is usually used in the field of mechanical processing, especially in mass production, to improve processing efficiency and ensure the accuracy of the hole position.

[0003] At present, since the end surface of the slider for the linear guide needs to be processed with multiple holes of different sizes, in the existing technology, it is generally processed by a CNC machining center. When an ordinary drilling machine is used to process the slider for the linear guide, most of the time it is a single-piece processing, which requires frequent disassembly and assembly of the workpiece (slider for the linear guide), resulting in low processing efficiency.

[0004] Therefore, the present application provides a drilling fixture to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a drilling fixture to solve the problem that the processing efficiency of fixing a single piece is too low when the existing fixture is used for processing a slider for a linear guide rail.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A drilling fixture comprises two symmetrically arranged U-shaped plates, a positioning plate is arranged between the middle parts of the two U-shaped plates, two fixing plates are symmetrically arranged between the two U-shaped plates with respect to the positioning plates, a plurality of first cylinders and a second cylinder are arranged on the side of the fixing plate facing the positioning plate, and a plurality of positioning grooves for placing two sliding blocks to be processed are opened on both sides of the positioning plate, a horizontally slidable pressure plate is matched at the side opening of the positioning groove, the pressure plate is fixed to the end of the machine shaft of the second cylinder, two wedge blocks are slidably installed in the middle part of the positioning groove, a V-shaped block is slidably arranged between the two wedge blocks, and the V-shaped block is fixed to the end of the machine shaft of the first cylinder.

[0009] Optionally, symmetrical inclined surfaces are provided on the opposite sides of the two wedge blocks, and the end of the V-shaped block away from the first cylinder is inserted between the two wedge blocks, and the two sides of the V-shaped block respectively abut against the inclined surfaces of the two wedge blocks.

[0010] Optionally, the taper of the V-shaped block matches the taper of the wedge-shaped block.

[0011] Optionally, the pressing plate abuts against a side of the sliding block to be processed away from the positioning plate.

[0012] Optionally, a connected bottom plate is provided between the bottoms of the two fixing plates, and the positioning plate is fixed between the middle parts of the two U-shaped plates and placed on the upper end surface of the bottom plate.

[0013] Optionally, the upper end surface of the bottom plate is provided with punched grooves corresponding to the positioning grooves on both sides of the positioning plate.

[0014] Optionally, the punching groove is arranged in parallel with the positioning plate, and the punching groove is located directly below the positioning groove.

[0019] At the same time, thanks to the cooperation of the bottom plate, the punching groove, the docking hole and the connecting pipe, by setting the punching groove below the positioning groove and using the docking hole and the connecting pipe to connect the external flushing water flow, when drilling the slider to be processed in the positioning groove, the drilling waste can be quickly discharged through the water flow channel composed of the punching groove, the docking hole and the connecting pipe, which can effectively avoid the accumulation of drilling waste on the fixture and affect the subsequent use.

[0020] In summary, the device can not only fix multiple workpieces at one time for drilling processing, but also can conveniently and quickly discharge drilling waste chips. The overall use effect is good, which is conducive to improving the efficiency of drilling processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a drilling fixture, including two symmetrically arranged U-shaped plates 1, a positioning plate 2 is arranged between the middle parts of the two U-shaped plates 1, two fixing plates 3 are symmetrically arranged between the two U-shaped plates 1 about the positioning plate 2, a plurality of first cylinders 4 and second cylinders 401 are arranged on the side of the fixing plate 3 facing the positioning plate 2, and a plurality of positioning grooves 201 for placing two sliders 8 to be processed are opened on both sides of the positioning plate 2, wherein the sliders 8 to be processed are placed at both ends of the positioning grooves 201.

[0036] At the same time, the side opening of the positioning groove 201 is equipped with a horizontally slidable pressure plate 7, which is fixed to the end of the machine shaft of the second cylinder 401. Two wedge blocks 5 are slidably installed in the middle of the positioning groove 201, and a V-block 6 is slidably arranged between the two wedge blocks 5. The V-block 6 is fixed to the end of the machine shaft of the first cylinder 4, so that the first cylinder 4 can drive the V-block 6 to squeeze in between the two wedge blocks 5, and use the two wedge blocks 5 to abut the side of the processing slide block 8, and the second cylinder 401 can drive the pressure plate 7 to move to abut the side of the processing slide block 8 away from the positioning plate 2, so that the inner wall of the positioning groove 201, the wedge block 5 and the pressure plate 7 are enclosed and matched, so that multiple slide blocks 8 to be processed can be clamped and fixed in batches.

[0037] In specific implementation, in this embodiment, the taper of the V-block 6 is adapted to the taper of the wedge block 5, wherein symmetrical inclined surfaces are provided on the opposite sides of the two wedge blocks 5, and the end of the V-block 6 away from the first cylinder 4 is inserted between the two wedge blocks 5, and the two sides of the V-block 6 respectively abut the inclined surfaces of the two wedge blocks 5, so that the V-block 6 can push and slide the two wedge blocks 5 along the inclined surfaces.
