Description

Technical Field

[0001] This utility model relates to the field of forming lathe tool grinding technology, specifically to a grinding device for forming lathe tool processing. Background Technology

[0002] Forming tools are specialized tools for machining the shaped surfaces of rotating bodies. The shape of their cutting edges is designed according to the contour of the workpiece. During the machining process, the shape and quality of the cutting edge of the forming tool have a significant impact on the machining accuracy and surface quality of the workpiece. However, since forming tools will gradually wear down during use, they need to be regularly polished by grinding equipment to restore their cutting performance.

[0003] Existing grinding equipment generates heat and dust when grinding cutting tools with a grinding disc. The heat may cause thermal deformation or phase transformation of the cutting tool material, thereby reducing the hardness and wear resistance of the cutting tool. The dust will permeate the workshop air, reduce air quality, and affect the working environment.

[0004] For example, the grinding device for diamond turning tool production disclosed in patent CN210678037U can collect the dust generated during grinding by using a protective cover, dust collection box and dust collection pipe set on the base to avoid dust pollution of the workshop environment. However, the heat generated during grinding is difficult to dissipate effectively. The high temperature environment will not only accelerate the aging and wear of the device components and shorten the service life of the equipment, but will also cause the turning tool to undergo chemical reactions such as oxidation and graphitization at high temperatures, further reducing its cutting performance.

[0005] Therefore, it is necessary to invent a grinding device for machining forming lathe tools to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a grinding device for machining forming lathe tools, in order to solve the problem that the heat generated during the grinding process is difficult to dissipate effectively.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for machining forming lathe tools, comprising a frame, a vertical arm disposed on the rear side above the frame, a cover box disposed on the front side above the frame, a grinding disc penetrating through the top of the cover box, a grinding table with a filter screen structure disposed inside the cover box, a water tank disposed at the rear end of the frame, an observation window made of transparent glass disposed on the front wall of the water tank, an annular tube disposed on the top surface inside the cover box, multiple nozzles disposed below the annular tube, the multiple nozzles surrounding the grinding disc, with the nozzle nozzles facing upwards towards the grinding table, a pyramidal funnel disposed at the bottom of the grinding table, a water collection trough disposed below the pyramidal funnel, and a filter disc slidably mounted inside the water collection trough.

[0008] Preferably, the front wall of the upright arm is provided with a slide table, which can slide up and down along the front wall of the upright arm. The top surface of the upright arm is provided with a cylinder, and the output end of the cylinder is connected to the top surface of the slide table, so that the motor installed above the slide table and the grinding disc connected thereto can be adjusted in the vertical direction to adapt to the grinding needs of workpieces of different heights.

[0009] Preferably, a motor is provided above the slide table, and the output end of the motor is connected to a rotating shaft. One end of the rotating shaft is connected to the grinding disc, and the grinding disc is driven to rotate at high speed through the rotating shaft, thereby realizing the grinding operation of the workpiece.

[0010] Preferably, the front of the enclosure is provided with a transparent cover. One side of the transparent cover is connected to the enclosure by a hinge, and the other side of the transparent cover is fastened to the enclosure by two latches. When the enclosure and the transparent cover are closed, a sealed environment is formed to prevent the leakage of debris and dust generated during the grinding process. At the same time, it reduces the interference of external factors on the grinding process and ensures the cleanliness of the grinding environment and the safety of the operators.

[0011] Preferably, clamping blocks are provided on the left and right sides above the grinding table, and hydraulic cylinders are provided on the outer walls of the left and right sides of the cover box. The output end of the hydraulic cylinder is connected to the side wall of the clamping block. The hydraulic cylinder drives the clamping block to move to the middle or the sides through extension and retraction, thereby realizing the clamping and releasing operation of the forming tool.

[0012] Preferably, a water pump is provided on one side of the outside of the water tank. The inlet of the water pump is connected to the outlet of the water tank. The outlet of the water pump is connected to a water guide pipe, which is connected to an annular pipe. The water pump draws the liquid in the water tank to the annular pipe, and then sprays it onto the grinding area through a nozzle below the annular pipe.

[0013] Preferably, the outer walls on both sides of the filter disc are provided with sliders, and the inner walls on both sides of the water collection tank are provided with matching grooves at the contact positions with the sliders. The cooperation between the sliders and the grooves allows the filter disc to slide smoothly in the water collection tank, making it easy to remove the filter disc from the water collection tank for cleaning or replacement.

[0014] Preferably, the outer walls on both sides of the water collection tank are provided with bearing seats, and a limiting plate is hinged on the bearing seats. A fixing bolt passes through the limiting plate and extends to the filter disc. A matching screw hole is opened at the contact position between the fixing bolt and the filter disc.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model forms a sealed environment by using a cover box and a transparent box, which effectively prevents dust generated during the grinding process from flying around, ensuring the cleanliness of the grinding environment and the safety of the operators. At the same time, through the water tank, water pump, water guide pipe and ring pipe in conjunction with multiple nozzles, water can be accurately sprayed onto the grinding area. During the grinding process, the grinding disc and cutting tool are cooled by water spraying, avoiding the impact of high temperature on grinding quality and tool life. Moreover, the sprayed water can also play a role in dust suppression, further reducing the diffusion of dust in the air and providing more suitable conditions for grinding work.

[0017] 2. This utility model uses a pyramidal funnel to collect wastewater mixed with impurities generated during spraying into a water collection tank. The filter discs in the water collection tank can achieve solid-liquid separation, trapping impurities inside the filter discs while allowing water to drain smoothly. In addition, sliders are provided on both sides of the filter discs, which cooperate with the sliding grooves on the inner wall of the water collection tank, allowing them to slide smoothly within the water collection tank. This makes it easy for operators to remove the filter discs from the water collection tank for cleaning or replacement, ensuring the continuous and efficient operation of the equipment and the filtration effect.

[0028] In this embodiment, the operator can check the water level and liquid status in the water tank 13 at any time through the observation window 14. When the water pump 15 is working, the grinding fluid in the water tank 13 is pumped to the annular pipe 17, and then sprayed evenly onto the grinding area by the nozzle 18, so as to achieve water spraying and cooling of the grinding disc 7 and the cutting tool while grinding. At the same time, the sprayed grinding fluid can reduce dust. After the grinding fluid mixes with impurities, it is collected in the water collection tank 20 through the pyramidal funnel 19. The filter plate 21 intercepts the impurities and achieves solid-liquid separation.

[0029] A slide 3 is provided on the front wall of the upright arm 2. The slide 3 can slide up and down along the front wall of the upright arm 2. A cylinder 4 is provided on the top surface of the upright arm 2. The output end of the cylinder 4 is connected to the top surface of the slide 3. A motor 5 is provided above the slide 3. The output end of the motor 5 is connected to a rotating shaft 6. One end of the rotating shaft 6 is connected to the grinding disc 7.

[0030] In this embodiment, the extension and retraction of the cylinder 4 can drive the slide 3 to move up and down, thereby driving the motor 5 and the grinding disc 7 to adjust their positions in the vertical direction. This design can adapt to the grinding needs of workpieces of different heights, improve the versatility and flexibility of the equipment, ensure that the grinding disc 7 maintains a suitable contact position with the workpiece, and improve the grinding quality.

[0031] A transparent cover 9 is provided on the front side of the cover box 8. One side of the transparent cover 9 is connected to the cover box 8 by a hinge, and the other side of the transparent cover 9 is fastened to the cover box 8 by two latches.

The output end of the hydraulic cylinder 12 is connected to the side wall of the clamping block 11.

[0032] In this embodiment, the transparent cover 9 allows the operator to observe the grinding process inside the cover 8. At the same time, it closes with the cover 8 to form a sealed environment, preventing dust leakage, reducing external interference, and ensuring a clean grinding environment and safe operation. The hydraulic cylinder 12 can extend and retract to drive the clamping block 11 to move, enabling the forming tool to be clamped and released quickly and accurately, ensuring the stability and precision of the tool during the grinding process.

[0033] The outer walls on both sides of the filter disc 21 are provided with sliders 22. The inner walls on both sides of the water collection tank 20 are provided with matching sliding grooves 23 at the contact positions with the sliders 22.

[0034] In this embodiment, the slider 22 cooperates with the slide groove 23 to allow the filter disc 21 to slide smoothly in the water collection tank 20, making it easy for operators to remove the filter disc 21 for cleaning or replacement. When the filter disc 21 slides to the appropriate position, the limiting plate 25 is rotated to fit against the side of the filter disc 21, and the fixing bolt 26 is tightened so that the fixing bolt 26 and the screw hole 27 are tightly engaged, fixing the filter disc 21 in the water collection tank 20, preventing the filter disc 21 from moving during the filtration process, and ensuring the filtration effect and stable operation of the equipment.

[0035] Working principle of this utility model:

[0036] Refer to the instruction manual appendix Figure 1-2 When using this utility model, firstly, add an appropriate amount of polishing liquid into the water tank 13 through the water inlet of the water tank 13 to ensure that the water level reaches the appropriate position, and open the transparent box cover 9. Place the forming tool to be polished on the polishing table 10 to prepare for clamping. By starting the two hydraulic cylinders 12, the hydraulic cylinders 12 push the clamping block 11 to move towards the middle until the forming tool is firmly clamped on the polishing table 10. Then, close the transparent box cover 9 and the cover box 8 with the lock. Then, start the cylinder 4. The cylinder 4 pushes the slide 3 to slide up and down along the front wall of the vertical arm 2. The motor 5 above the slide 3 and the polishing disc 7 connected to it move accordingly. Then, adjust the polishing disc 7 to a suitable contact position with the tool. At this time, the motor 5 can be started to drive the rotating shaft 6 and the polishing disc 7 to rotate and start polishing the forming tool.

[0037] Refer to the instruction manual appendix Figure 3-4 When using this utility model, during the grinding process, the water pump 15 is started. The water pump 15 pumps the grinding fluid in the water tank 13 to the water outlet through the water inlet, and then delivers it to the annular pipe 17 through the water guide pipe 16. The grinding fluid is evenly sprayed onto the grinding area from multiple nozzles 18 arranged around the grinding disc 7 below the annular pipe 17, so as to achieve water cooling of the grinding disc 7 and the cutting tool while grinding. At the same time, the sprayed grinding fluid can play a role in dust reduction.

[0038] Refer to the instruction manual appendix Figure 5-6 When using this utility model, the sprayed polishing fluid carrying polishing debris is collected in the water collection tank 20 through the pyramidal funnel 19. At the same time, the filter disc 21 inside the water collection tank 20 can trap fine debris and impurities in the polishing fluid after sedimentation. When it is found that the filtration speed of the filter disc 21 is significantly slower or the filtration effect is poor, the filter disc 21 should be cleaned in time. At this time, simply loosen the fixing bolt 26 so that the sliders 22 on both sides of the filter disc 21 can slide in the sliding grooves 23 on both sides of the inner wall of the water collection tank 20. The filter disc 21 can then be removed from the water collection tank 20 for cleaning or replacement. After cleaning, the filter disc 21 can be reinstalled in the water collection tank 20 and the fixing bolt 26 can be tightened to fix it.
