Technical Field
[0001] This utility model relates to the technical field of equipment for processing hydraulic valve cores, and more specifically, to honing fixtures for hydraulic valve core holes. Background Technology
[0002] Honing is characterized by high machining accuracy, good surface quality, wide machining range, small cutting allowance, and strong hole correction capability. Honing has a wide processing range, and in mass production, using a dedicated honing machine is more economical and reasonable. For some parts, honing has even become a typical finishing method. Against this backdrop, honing by honing machine is gradually becoming the trend. However, during the use of honing machines, issues such as tool collision, tool deviation, and collision with the workpiece frequently occur. Therefore, honing tooling becomes particularly important.
[0003] The existing publicly available technology, application number CN202320719152.1, discloses a device for processing hydraulic valve cores. The honing fixture for the hydraulic valve core hole includes a base, a transition plate fixedly mounted on the base, an upright side plate on one side of the transition plate, and a guide sleeve base fixedly connected to the top of the side plate by a locating pin and screws. The guide sleeve base has a through hole in its center for inserting the guide sleeve. A locating base is provided in the center of the transition plate for placing the hydraulic valve core to be honed. The guide sleeve has a through hole in its center for a honing tool to pass through. This through hole is vertically aligned with a honing tool locating cylinder protruding from the upper surface of the locating base. The honing tool passes through the hydraulic valve core hole and abuts against the locating cylinder.
[0004] However, the above-mentioned patent still has certain drawbacks in use: although it can hone the hydraulic valve core, it requires frequent replacement of different positioning chassis and guide sleeves when processing different types of hydraulic valve cores, which increases the cost of use, reduces the practicality of the device, and the overall effect is not ideal.

A movable side plate 11 is slidably connected to the outer periphery of the adjusting plate 7. A guide sleeve 12 is installed at the top of the movable side plate 11. Several sets of guide sleeves 15 are installed around the inside of the guide sleeve 12. Several sets of adjusting screws 16 are symmetrically rotatably connected to the surface of the guide sleeves 15. One end of the adjusting screw 16 passes through one side of the guide sleeve 12. A positioning base 2 is installed at the top of the base 1. An adjusting rod 4 is slidably connected to the middle of the top of the positioning base 2. A bearing plate 6 is fixedly installed at the top of the adjusting rod 4. Several sets of positioning bosses 18 are slidably connected to the top of the bearing plate 6. The guide sleeve 12 and the guide sleeve 15 are used to guide and limit the honing cutter 14, ensuring that it can smoothly cooperate with the core hole, ensuring the working accuracy and improving the processing quality.
[0028] In one embodiment, a second adjustment groove 10 is provided at the bottom of the interior of the movable side plate 11. The second adjustment groove 10 is provided to facilitate the movement and use of the adjustment plate 7, thereby facilitating the adjustment of the height of the movable side plate 11, expanding the overall adjustable range, and improving the overall applicability.
[0029] In one embodiment, a first adjustment groove 3 is provided inside the positioning chassis 2. The first adjustment groove 3 is provided to facilitate the movement of the adjustment rod 4, thereby facilitating the height adjustment of the support plate 6.
[0030] In one embodiment, a third adjustment groove 19 is provided at the top of the inner part of the support plate 6. A moving block 20 is slidably connected inside the third adjustment groove 19. One end of the moving block 20 passes through one side of the third adjustment groove 19 and is connected to the positioning boss 18.

This adjusts the height of the bearing plate 6 and changes the distance between it and the guide sleeve 12, thus adapting to different models of hydraulic valve core holes 17. After the height adjustment is completed, the spacing of the positioning bosses 18 on the surface of the sliding bearing plate 6 can be changed, facilitating the subsequent outward expansion and fixing of the hydraulic valve core hole 17. This prevents misalignment of the hydraulic valve core hole 17 and avoids workpiece movement, ensuring the subsequent processing quality. After the above adjustments are completed, the adjusting screw 16 inside the guide sleeve 12 is rotated. The spacing between the guide sleeves 15 can be changed to accommodate honing cutters 14 of different sizes and hydraulic valve core holes 17. After all adjustments are completed, the honing cutter 14 can be inserted into the hydraulic valve core hole 17, and the spindle 13 at its top can be connected to the external drive device to realize the machining operation of the hydraulic valve core hole 17. In the overall operation process, the adjustable structure expands the applicability of the device to meet the processing needs of different types of workpieces.
