Description

Technical Field

[0001] This utility model belongs to the field of grinding technology, specifically relating to a grinding wheel device for lathe tools. Background Technology

[0002] Lathe tools are used on various lathes to machine external diameters, internal holes, end faces, threads, etc. Currently, lathe tools are mainly ground manually on grinding wheels, which requires workers to have a high level of skill.

[0003] Existing Chinese patent CN221891535U discloses a tool sharpening machine, including a worktable with a tool sharpening holder on its upper surface; a lathe tool sharpening mechanism is located on one side of the tool sharpening holder, and the tool sharpening holder has a clearance groove for the drive end of the tool sharpening mechanism to be inserted; a lathe tool angle adjustment mechanism is engaged with the upper surface of the tool sharpening holder, and a lathe tool mounting bracket is provided on one side wall of the tool angle adjustment mechanism, with a lathe tool slidably fitted inside the mounting bracket; a linear drive mechanism is located on one side wall of the tool sharpening holder and on one side of the tool sharpening mechanism, and the drive end of the linear drive mechanism can abut against one end of the lathe tool, eliminating the need for the worker to move the lathe tool for sharpening, effectively avoiding the instability of the worker holding the lathe tool, and avoiding the safety hazards that exist when manually holding the lathe tool for sharpening.

[0004] However, the tool angle adjustment mechanism of the existing tool grinding machine can only drive the tool to rotate horizontally to adjust the contact surface between the tool face and the grinding wheel. Since different tools have different cutting edge deflection angles, and some tools have multiple cutting edges with different angles, when a tool with multiple cutting edges with different tilt angles is placed in the tool mounting bracket, the tool face to be ground may not be perpendicular to the grinding bracket. Therefore, the tool cannot be spatially adjusted during grinding with the aforementioned tool grinding machine. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a grinding wheel device for lathe tools, which solves the problem that existing grinding machines cannot adjust the spatial angle of the lathe tools during grinding because different lathe tools have different cutting edge angles, and some lathe tools have multiple cutting edges with different angles. When a lathe tool with multiple cutting edges with different inclination angles is placed in a lathe tool mounting frame, the cutting edge of the lathe tool to be ground may not be perpendicular to the grinding frame.

[0006] The technical solution adopted by this utility model is as follows: a grinding wheel device for lathe tools, including a grinding table, wherein a mounting bracket is provided on the grinding table;

[0008] The adjusting cylinder is mounted on the mounting bracket and has a hollow structure. The ball is rotatably fitted inside the adjusting cylinder. The connecting rod is connected to the ball. The top of the adjusting cylinder has a clearance opening. The upper end of the connecting rod passes through the clearance opening of the adjusting cylinder and connects to the bottom of the sliding sleeve. A cutting tool is slidably fitted inside the sliding sleeve. The limiting component is mounted on the adjusting cylinder. The driving end of the limiting component is located inside the adjusting cylinder and can abut against the bottom of the ball to limit the ball.

[0009] A grinding mechanism is mounted on a mounting bracket, with the grinding end of the grinding mechanism facing the cutting face of the lathe tool, and the cutting face of the lathe tool can abut against the grinding end of the grinding mechanism.

[0010] Furthermore, the limiting component includes a handle, a screw, an adjusting block, an abutment block, and an adjusting groove;

[0011] The adjusting block is vertically slidably sleeved inside the adjusting cylinder. An adjusting groove is provided on the outer side wall of the adjusting block. The upper side of the adjusting groove is an inclined surface, and the outer end of the inclined surface is inclined upward.

[0012] The screw is threaded onto the side wall of the adjusting cylinder. The outer end of the screw is located outside the adjusting cylinder and is fixedly connected to the handle. The inner end of the screw penetrates the side wall of the adjusting cylinder, extends into the adjusting cylinder, and is fixedly connected to the abutment block. The abutment block can extend into the adjusting groove and abut against the inclined surface of the adjusting groove. The abutment block can drive the adjusting block to move vertically within the adjusting cylinder. The top of the adjusting block can abut against the bottom of the sphere.

[0013] Furthermore, it also includes a transparent protective cover, the lower end of which is fixedly connected to the front end of the top of the mounting bracket, and the transparent protective cover is placed above the grinding mechanism and the adjustment mechanism.

[0014] Furthermore, the grinding mechanism includes a grinding wheel and a motor. The motor is fixedly mounted on the grinding table and located on the rear side of the mounting bracket. The drive end of the motor is forward and connected to the grinding wheel, and the cutting face of the cutting tool can abut against the grinding wheel.

[0015] Furthermore, a waste collection frame is also provided on the grinding table, which is located below the mounting frame and the grinding wheel.

[0016] Furthermore, it also includes a linear drive mechanism, which is mounted on a mounting bracket, and the drive end of the linear drive mechanism can abut against the end of the cutting tool away from the cutting tool face.

[0017] Furthermore, the linear drive mechanism includes a cylinder and an abutment plate. The cylinder is horizontally fixedly mounted on the mounting bracket and located on the right side of the sliding sleeve. The driving end of the cylinder is to the left and fixedly connected to the abutment plate. The abutment plate can abut against the end of the cutting tool away from the cutting tool face.

[0018] The beneficial effects of this utility model are as follows: By rotating the ball inside the adjusting cylinder, the angles of the sliding sleeve and the cutting tool can be flexibly adjusted, ensuring that the cutting surfaces of the cutting tool at different angles can be ground at the corresponding angles. It can adjust the sliding sleeve and the cutting tool in space at multiple angles.

[0029] Example 1:

[0030] like Figures 1-5 As shown, a grinding wheel device for lathe tools includes a grinding table 1, on which a mounting bracket 11 is provided;

[0031] Adjustment mechanism 2, which includes adjustment cylinder 21, ball 22, connecting rod 23, limiting component 3 and sliding sleeve 24;

[0032] The adjusting cylinder 21 is mounted on the mounting frame 11. The adjusting cylinder 21 has a hollow structure. The ball 22 is rotatably fitted inside the adjusting cylinder 21. The connecting rod 23 is connected to the ball 22. The top of the adjusting cylinder 21 has a clearance opening 36. The upper end of the connecting rod 23 passes through the clearance opening 36 of the adjusting cylinder 21 and is connected to the bottom of the sliding sleeve 24. A cutting tool 8 is slidably fitted inside the sliding sleeve 24. The limiting component 3 is mounted on the adjusting cylinder 21. The driving end of the limiting component 3 is located inside the adjusting cylinder 21. The driving end of the limiting component 3 can abut against the bottom of the ball 22 to limit the ball 22. In this embodiment, the bottom of the adjusting cylinder 21 is fixedly connected to the mounting frame 11. The diameter of the cross-section of the clearance opening 36 is smaller than the diameter of the cross-section of the cavity of the adjusting cylinder 21, so that the ball 22 can be rotatably fitted inside the adjusting cylinder 21.

[0033] A grinding mechanism 4 is mounted on the mounting bracket 11. The grinding end of the grinding mechanism 4 faces the cutting face of the lathe tool 8, and the cutting face of the lathe tool 8 can abut against the grinding end of the grinding mechanism 4. Specifically, the shank of the lathe tool 8 is slidably sleeved inside the sliding sleeve 24. One end of the cutting face of the lathe tool 8 passes through the sliding sleeve 24 and extends towards the grinding end of the grinding mechanism 4. The outer peripheral wall of the shank of the lathe tool 8 is in contact with the inner peripheral wall of the sliding sleeve 24, so that the lathe tool 8 can slide along the inner wall of the sliding sleeve 24, avoiding angular deviation of the lathe tool 8 during the grinding process and improving grinding accuracy.

[0034] like Figure 4 and Figure 5 As shown, as a preferred embodiment, the limiting component 3 includes a handle 31, a screw 32, an adjusting block 33, an abutment block 34, and an adjusting groove 35;

[0035] The adjusting block 33 is vertically slidably sleeved inside the adjusting cylinder 21. An adjusting groove 35 is provided on the outer side wall of the adjusting block 33. The upper side of the adjusting groove 35 is an inclined surface, and the outer end of the inclined surface is inclined upward.

[0036] The screw 32 is threaded onto the side wall of the adjusting cylinder 21. The outer end of the screw 32 is located outside the adjusting cylinder 21 and is fixedly connected to the handle 31. The inner end of the screw 32 penetrates the side wall of the adjusting cylinder 21 and extends into the adjusting cylinder 21, and is fixedly connected to the abutment block 34. The abutment block 34 can extend into the adjusting groove 35 and abut against the inclined surface of the adjusting groove 35. The abutment block 34 can drive the adjusting block 33 to move vertically within the adjusting cylinder 21. The top of the adjusting block 33 can abut against the bottom of the ball 22. In this embodiment, when the angle of the sliding sleeve 24 needs to be adjusted according to the angle of the cutting surface of the lathe tool 8 to be ground, the handle 31 is rotated to drive the screw 32 to move outward, so that the screw 32 drives the abutment block 34 to move outward. At this time, the abutment block 34 moves outward along the inclined surface of the adjustment groove 35, driving the adjustment block 33 to slide downward, so that the top of the adjustment block 33 disengages from the bottom of the ball 22. At this time, the ball 22 can be rotated to drive the connecting rod 23 to adjust the angle of the sliding sleeve 24, so that the cutting surface of the lathe tool 8 to be ground in the sliding sleeve 24 is adjusted to the corresponding angle. Then, the handle 31 is rotated in the opposite direction to drive the screw 32 to move inward, so that the screw 32 drives the abutment block 34 to move inward. At this time, the abutment block 34 moves inward along the inclined surface of the adjustment groove 35, driving the adjustment block 33 to slide upward until the top of the adjustment block 33 abuts against the bottom of the ball 22, thereby limiting the ball 22 so that the ball 22 can no longer rotate, thereby fixing the angle of the sliding sleeve 24 and the lathe tool 8, which facilitates the subsequent grinding of the cutting surface of the lathe tool 8.

[0037] In this embodiment, the top of the adjusting block 33 is provided with an abutment groove, and the lower part of the ball 22 can abut in the abutment groove. By abutting the lower part of the ball 22 through the abutment groove, a larger contact area can be provided, so that the ball 22 can remain stable and will not shift when subjected to external force. Due to the close contact between the abutment groove and the ball 22, the vibration caused by the shaking of the ball 22 can be reduced, further improving the stability of the grinding process.

[0038] like Figure 3 As shown, as a preferred embodiment, a transparent protective cover 5 is also included. The lower end of the transparent protective cover 5 is fixedly connected to the front end of the top of the mounting bracket 11. The transparent protective cover 5 covers the grinding mechanism 4 and the adjustment mechanism 2. By setting the transparent protective cover 5, the sand and debris generated during the grinding process can be blocked, preventing injury to workers near the grinding table 1. The transparent protective cover 5 is made of polycarbonate, a high-strength, high-transparency plastic material with excellent impact resistance and temperature resistance.

[0039] As a preferred embodiment, the grinding mechanism 4 includes a grinding wheel 41 and a motor 42. The motor 42 is fixedly mounted on the grinding table 1 and located behind the mounting bracket 11. The drive end of the motor 42 faces forward and is connected to the grinding wheel 41, allowing the cutting face of the cutting tool 8 to abut against the grinding wheel 41. In this embodiment, the grinding wheel 41 is a silicon carbide grinding wheel 41. Silicon carbide grinding wheels 41 have high abrasive hardness and good cutting performance. The motor 42 drives the grinding wheel 41 to rotate, grinding the cutting face of the cutting tool 8, making grinding convenient.

[0040] As a preferred embodiment, the grinding table 1 is further provided with a waste collection frame 6, which is placed on the grinding table 1 and located below the mounting frame 11 and the grinding wheel 41. By providing the waste collection frame 6 below the mounting frame 11 and the grinding wheel 41, it is convenient to collect the iron filings generated during the grinding of the cutting tool 8 by the grinding wheel 41. Specifically, there is a gap between the grinding wheel 41 and the rear side wall of the mounting frame 11, which facilitates the waste falling into the waste collection frame 6.

[0041] As a preferred embodiment, the system further includes a linear drive mechanism 7, which is mounted on the mounting bracket 11. The drive end of the linear drive mechanism 7 is capable of abutting against the end of the cutting tool 8 that is away from the cutting face of the cutting tool 8. The linear drive mechanism 7 includes a cylinder 71 and an abutment plate 72. The cylinder 71 is horizontally and fixedly mounted on the mounting bracket 11 and located on the right side of the sliding sleeve 24. The drive end of the cylinder 71 is directed to the left and fixedly connected to the abutment plate 72. The abutment plate 72 is capable of abutting against the end of the cutting tool 8 that is away from the cutting face of the cutting tool 8. By setting a linear drive mechanism 7 to drive the cutting tool 8 to move during grinding, uniform and stable grinding of the cutting tool 8 can be achieved, thereby improving the machining accuracy and surface quality of the cutting tool 8. The use of the linear drive mechanism 7 reduces the need for manual operation, lowers the risk of injury to operators, and improves the stability and safety of the grinding process. Through the cooperation of the cylinder 71 and the abutment plate 72, the feed rate of the cutting tool 8 can be precisely controlled. The cylinder 71 drives the abutment plate 72 to move smoothly, ensuring the stability and consistency of the grinding process.

[0042] The working principle of this utility model is as follows:

[0043] In use, according to the position and angle of the cutting face to be ground on the lathe tool 8, slide the tool holder into the sliding sleeve 24, so that the cutting face to be ground faces the grinding wheel 41. Then, turn the handle 31 to drive the screw 32 to move outward, so that the screw 32 drives the abutment block 34 to move outward. At this time, the abutment block 34 moves outward along the inclined surface of the adjusting groove 35, driving the adjusting block 33 to slide downward, so that the top of the adjusting block 33 disengages from the bottom of the ball 22. At this time, the ball 22 can be rotated to drive the connecting rod 23 to adjust the angle of the sliding sleeve 24, so that the cutting face of the lathe tool 8 to be ground in the sliding sleeve 24 is adjusted to the corresponding angle. Then, turn the handle 31 in the opposite direction to drive the screw 32 to move inward, so that the screw 32 drives the abutment block 34. Moving inward, the abutment block 34 moves inward along the inclined surface of the adjustment groove 35, causing the adjustment block 33 to slide upward until the top of the adjustment block 33 abuts against the bottom of the ball 22, thereby limiting the ball 22 so that it can no longer rotate, thus fixing the angle between the sliding sleeve 24 and the cutting tool 8, which facilitates the subsequent grinding of the cutting tool 8. The end of the cutting tool 8 away from the cutting tool 8 can be manually pushed so that the cutting tool 8 to be ground comes into contact with the grinding wheel 41 for grinding. Alternatively, the cylinder 71 can be activated to drive the abutment plate 72 to abut against the end of the cutting tool 8 away from the cutting tool 8 and push the cutting tool 8 toward the grinding wheel 41 so that the cutting tool 8 to be ground comes into contact with the grinding wheel 41 for grinding.

[0044] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of ​​the present invention.
