Description

Technical Field

[0001] This utility model relates to the field of coal exploration, and in particular to a repair device for machining tools. Background Technology

[0002] A lathe tool is a cutting tool used for turning operations. During use, it wears down, affecting machining accuracy and requiring timely grinding and repair. For conventional lathe tools, simply fixing the tool body and then grinding the cutting edges with a grinding wheel is sufficient. However, for some specially designed lathe tools, such as triangular lathe tools, with their small inserts and multiple cutting edges, conventional repair devices cannot fix and grind them, making repair impossible. Utility Model Content

[0003] The purpose of this invention is to provide a repair device for machining tools. This device can accurately position and fix triangular blades, enabling the grinding wheel to stably grind and repair the blades, thereby improving the quality and efficiency of tool repair.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a repair device for machining tools, comprising a base and a cover plate, wherein the top of the base is provided with a plurality of positioning threaded holes, the cover plate is provided with positioning bolts that match the positioning threaded holes, the cover plate is detachably and fixedly connected to the top of the base, the cover plate is provided with a limiting groove that matches the tool, a pressure plate is provided above the limiting groove, and the pressure plate is detachably and fixedly connected to the cover plate.

[0005] Optionally, the top of the base is configured as a ramp, with the limiting groove located at the higher end of the ramp.

[0006] Optionally, a positioning plate is provided on the edge of the base.

[0007] Optionally, the cover plate is provided with an adjustment threaded hole, and the pressure plate is provided with an adjustment bolt that matches the adjustment threaded hole.

[0008] Optionally, a buffer layer is provided at the bottom of the pressure plate.

[0009] Optionally, a positioning block is provided at the bottom of the base.

[0010] The repair device for machining tools of this utility model has the following advantages:

[0011] (1) The triangular blade is placed in the limiting groove and fits against the edge of the limiting groove to achieve precise positioning of the blade. Then the pressure plate is connected to the cover plate to achieve stable fixing of the blade. Finally, the base is placed on the grinding workbench and the blade is repaired using grinding tools.

[0012] (2) The ramp allows the blade to slide into the limiting groove, which helps to position the blade and prevents it from falling out of the limiting groove, thus avoiding damage to the blade.

[0013] (3) Adjusting bolts can adjust the height of the pressure plate and fix blades of different thicknesses. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model.

[0015] Figure 2 This is a side view of the present invention. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1-2 As shown, a repair device for machining tools includes a base 1 and a cover plate 2. A positioning block 3 is provided at the bottom of the base 1, and the top of the base 1 is sloped. Two positioning threaded holes are symmetrically arranged on the top of the base 1. Positioning bolts 4 that match the positioning threaded holes are provided on the cover plate 2. The cover plate 2 is detachably and fixedly connected to the top of the base 1 by the positioning bolts 4. L-shaped positioning plates 5 are provided at the two bottom corners of the base 1. The cover plate 2 slides along the slope onto the positioning plates 5, and the two corners of the cover plate 2 fit against the positioning plates 5, thus limiting and positioning the cover plate 2 to ensure its installation accuracy.

[0018] The cover plate 2 is attached to the top of the base 1. The cover plate 2 is provided with a limiting groove 6 that matches the tool. The limiting groove 6 is located at the higher end of the slope. A pressure plate 7 is provided above the limiting groove 6. The pressure plate 7 is parallel to the limiting groove 6. The cover plate 2 is provided with an adjustment thread hole. The pressure plate 7 is provided with an adjustment bolt 8 that matches the adjustment thread hole. The pressure plate 7 is detachably and fixedly connected to the cover plate 2 by the adjustment bolt 8. A buffer layer 9 is provided at the bottom of the pressure plate 7.

[0019] Different cover plates 2 have different limiting groove 6 structures, suitable for different cutting tools. First, the cover plate 2 is placed on the base 1, and then the cover plate 2 is fixed with the positioning bolt 4. The limiting groove 6 is inclined inward. When the triangular blade 10 is placed in the limiting groove 6, the blade 10 will slide along the slope to the bottom of the limiting groove 6, and the two sides of the blade 10 will fit with the two sides of the limiting groove 6, achieving fast and accurate positioning of the blade 10. Then, the pressure plate 7 is pressed on the top of the blade 10, and the pressure of the pressure plate 7 on the blade 10 is adjusted by adjusting the bolt 8. The buffer layer 9 can be made of rubber, which can improve the fixing effect of the pressure plate 7 on the blade 10, and avoid excessive pressure that may damage the blade 10. After the blade 10 is fixed, the base 1 is placed on the grinding worktable, and the positioning block 3 matches the positioning structure of the grinding worktable. Finally, the blade 10 is ground and repaired using grinding tools. The device has a simple structure, is easy to install, and can accurately fix cutting tools with special structures, ensuring the quality and efficiency of grinding and repair.

[0020] The embodiments described above are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the protection scope of this utility model.
