Description

Technical Field

[0001] The invention relates to the technical field of parts grinding, in particular to a high-efficiency grinding device for machining mechanical parts. Background Art

[0002] In precision parts processing, part grinding is usually divided into multiple processes to ensure that the required dimensional accuracy and surface finish are achieved. The following is a brief description of each process:

[0003] Rough grinding: remove most of the excess to initially meet the size and shape requirements of the part.

[0004] Semi-finishing grinding: further reduce the allowance and improve the accuracy and surface finish.

[0005] Fine grinding: Micro-grinding to get close to the final size.

[0006] Superfinishing or mirror grinding: Final grinding to make the surface of the part extremely smooth, with a surface roughness usually reaching Ra 0.01 microns or less.

[0007] During the super-finishing or mirror-finishing stages, the grinding wheel is very fine, resulting in low grinding efficiency. To improve efficiency, the part size is usually ground to the upper tolerance limit or slightly above it (e.g., half a thread) during the fine-finishing stage. This way, only a small amount of grinding is required during super-finishing or mirror-finishing to achieve tolerance. However, this strategy also has risks:

[0008] If machine creep (intermittent, uneven movement at low speeds) occurs during the fine grinding stage while the grinding wheel is being dressed, it can cause spiral patterns to appear on the part surface. These patterns may be difficult to detect due to the high surface roughness after fine grinding. However, in the subsequent superfinishing or mirror grinding stages, when the surface finish is significantly improved, these patterns become apparent. If the part dimensions are already within tolerance at this point and there is no room for re-dressing, the part will have to be scrapped.

[0009] The impact of excessive stock: To avoid these issues, some stock is often left during the fine grinding stage for superfinishing or mirror grinding. This way, even if problems are discovered, there's still ample stock for refinishing. However, because the grinding wheels used in superfinishing or mirror grinding are too fine and the grinding speed is slow, excessive stock can seriously affect processing efficiency.

[0010] Therefore, during the fine grinding stage, a balance must be struck: minimizing the amount of allowance required for superfinishing or mirror grinding to improve efficiency, while ensuring sufficient allowance to address potential quality issues. This requires precise control of the fine grinding process, ensuring wheel dressing and grinding process stability to avoid issues such as machine tool creep. Summary of the Invention

[0019] Preferably, both of the pipes are made of transparent glass, and the outer walls of the pipes are marked with scale lines.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention cooperates with the arrangement of pipes, boxes and alarms. If the machine tool creeps and crawls, the original motion state is changed. Under the action of inertia, the liquid in the box causes the liquid level in one of the pipes to rise. When the liquid level hits the guide rod, the circuit between the battery and the alarm is fully connected, causing the alarm to sound an alarm, thereby reminding the operator to pay attention to re-grinding the grinding wheel.

In this way, there is no need to weigh the amount of margin in the fine grinding stage, and the margin of super-fine grinding or mirror grinding can be reduced as much as possible to improve efficiency, and there is no risk of insufficient margin.

[0022] The present invention is used in conjunction with the arrangement of a push rod and the like. When the grinding wheel is being repaired, when the table drives the tailstock and the diamond pen to move to one side of the grinding wheel, the push rod moves to one side of the guide block. Before the diamond pen contacts the grinding wheel, the push rod contacts the guide block, so that the guide block pushes the push rod, and the moving push rod drives the gear to rotate, and the rotating gear drives the stop shaft to rotate, so that the stop shaft rotates ninety degrees. At this time, the conductive liquid in the box can enter the pipeline through the perforation. After the grinding wheel is repaired, when the product is ground, as the table moves, one end of the push rod will move out of the side of the guide block. At this time, the spring will push the push rod to reset, and the reset push rod drives the gear and the stop shaft to rotate and reset. After the stop shaft is reset, the perforation cannot connect the pipeline and the box. At this time, even if the components in the box are affected by the inertia of the table reversal, the liquid in the box will not enter the pipeline, thereby increasing the liquid in the pipeline, thereby avoiding the alarm from giving a false alarm during normal grinding.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] See also Figures 1-11A high-efficiency grinding device for machining mechanical parts includes a machine tool body 1, a table 2, a tailstock 3 and a diamond pen 4. The upper surface of the table 2 is slidably connected to a fixed seat 5, and the side wall of the fixed seat 5 is threadedly connected to a first bolt 6. One end of the first bolt 6 passes through the fixed seat 5 and abuts against the table 2. The upper surface of the table 2 is fixedly connected to a box 7, and the upper surface of the box 7 is connected to two shells 8. The upper surfaces of the two shells 8 are connected to a connector 9, and one end of the connector 9 is connected to a pipe 10. The side wall of the shell 8 is provided with a through hole 11, and a stop shaft 12 is provided in the through hole 11. The side wall of the stop shaft 12 is provided with a through hole 13. An outer cover 14 is provided above the box body 7, and a battery slot 15 is provided on the side wall of the outer cover 14. A battery 16 is provided in the battery slot 15. A sealing rod 17 is provided at one end of the two pipes 10, and two guide rods 19 are slidably connected to the side wall of the sealing rod 17. One end of the guide rod 19 passes through the sealing rod 17 and extends into the pipe 10. The battery 16 is electrically connected to the guide rod 19, and the battery 16 is electrically connected to the box body 7. An alarm 20 is fixedly connected to the lower surface of the sealing rod 17, and the alarm 20 is electrically connected to the battery 16, and the alarm 20 is electrically connected to the guide rod 19. A control component is provided in the outer cover 14.

[0037] It can be seen from the above structure that: by setting up the pipeline 10, the box 7 and the alarm 20 for use in conjunction, if the machine tool creeps, the original motion state is changed, and the liquid in the box 7 causes the liquid level in one of the pipes 10 to rise under the action of inertia. When the liquid level hits the guide rod 19, the circuit between the battery 16 and the alarm 20 is fully connected, causing the alarm 20 to sound an alarm, thereby reminding the operator to pay attention to re-grinding the grinding wheel. Until the grinding wheel is repaired, there is no problem of creeping, indicating that the grinding wheel has been repaired and can be used. In this way, there is no need to weigh the amount of margin in the fine grinding stage, and the margin of super-fine grinding or mirror grinding can be minimized to improve efficiency, and there will be no risk of insufficient margin.

[0038] Furthermore, the box body 7 includes a first half box 701 and a second half box 702, an elastic membrane 21 is arranged between the first half box 701 and the second half box 702, and a counterweight 22 is fixedly connected to the side wall of the elastic membrane 21. A screw 703 is arranged on one side of the first half box 701, and one end of the screw 703 passes through the first half box 701 and the second half box 702, and two nuts 704 are threaded on the outer wall of the screw 703; by setting the counterweight 22 and the elastic membrane 21 for use together, when the grinding wheel is normally repaired, the table 2 moves at a uniform speed. If the machine tool creeps, the original motion state is changed. At this time, the counterweight 22 will not change much in the original motion state, and the elastic membrane 21 is deformed, so that the liquid on one side of the box body 7 is squeezed by the counterweight 22 and the elastic membrane 21 and enters the pipe 10.

[0039] Furthermore, the control component includes a gear 23 fixedly sleeved on the outer wall of the gear shaft 12, and a push rod 24 is provided on one side of the gear 23, and a tooth groove 25 is provided on one side wall of the push rod 24, and the tooth groove 25 is engaged with the gear 23, and a clearance hole is provided at one end of the push rod 24, and a spring 26 and a limit rod 27 are provided in the clearance hole, and the limit rod 27 is fixedly connected to the outer cover 14, and a track 28 is fixedly connected to one side wall of the machine tool body 1, and a guide block 29 is slidably connected to the inner wall of the track 28, and a second bolt 30 is threadedly connected to the side wall of one side of the guide block 29, and one end of the second bolt 30 passes through the guide block 29 and abuts against the track 28, and one end of the push rod 24 passes through the outer cover 14 and extends to one side of the guide block 29; by setting the push rod 24 and the like for use in conjunction, when the grinding wheel is being repaired, when the table 2 drives the tailstock 3 and the diamond pen 4 to move to one side of the grinding wheel, the push rod 24 moves to one side of the guide block 29, and the diamond pen 4 is pressed against the track 28. Before the pen 4 contacts the grinding wheel, the push rod 24 contacts the guide block 29, so that the guide block 29 pushes the push rod 24, and the moving push rod 24 drives the gear 23 to rotate, and the rotating gear 23 drives the stop shaft 12 to rotate, so that the stop shaft 12 rotates ninety degrees. At this time, the conductive liquid in the box body 7 can enter the pipe 10 through the perforation 13. After the grinding wheel is repaired, when the product is ground, as the table 2 moves, one end of the push rod 24 will move out of the side of the guide block 29. At this time, the spring 26 will push the push rod 24 to reset. The reset push rod 24 drives the gear 23 and the stop shaft 12 to rotate and reset. After the stop shaft 12 is reset, the perforation 13 cannot connect the pipe 10 with the box body 7. At this time, even if the components in the box body 7 are affected by the inertia of the reversing of the table 2, the liquid in the box body 7 will not enter the pipe 10, increasing the liquid in the pipe 10, thereby avoiding the alarm 20 from giving a false alarm during normal grinding.

[0040] Furthermore, a tough rod 31 is connected to one side wall of the retaining shaft 12, and a knocking ball 32 is fixedly connected to one end of the tough rod 31, a copper plate 33 is fixedly connected to one side wall of the outer cover 14, and a sound hole 34 is provided on the side wall of the outer cover 14 close to the copper plate 33; by arranging the tough rod 31 and the knocking ball 32 for use together, when the retaining shaft 12 rotates ninety degrees and cuts off the connection between the pipe 10 and the box body 7, the knocking ball 32 can knock on the copper plate 33, causing the copper plate 33 to make a sound to remind the operator that the grinding wheel has been repaired to the end.

[0041] Furthermore, a connecting hole 35 is opened on one side wall of the sealing rod 17; by providing the connecting hole 35, the gases in the two pipes 10 can circulate with each other, avoiding the generation of negative pressure or high pressure in the pipe 10 and affecting the rise and fall of the liquid in the pipe 10.

[0042] Furthermore, a soft sleeve is provided on the outer wall of the retaining shaft 12 , and the outer wall of the soft sleeve is interference fit with the inner wall of the through hole 11 ; by providing the soft sleeve, the sealing performance of the retaining shaft 12 can be improved.

[0043] Furthermore, a connecting plate 18 is provided between the two guide rods 19, and the connecting plate 18 is fixedly connected to the two guide rods 19; by providing the connecting plate 18, the two guide rods 19 can be connected, and then when adjusting, the two guide rods 19 can be adjusted at the same time.

[0044] Furthermore, both pipes 10 are made of transparent glass, and the outer walls of the pipes 10 are marked with scale lines. By providing the pipes 10 with transparent glass, when the battery 16 is out of power, the user can see the scale of the pipes 10 with the naked eye.

[0045] In the present invention, before use, the box 7 is filled with conductive liquid, and the conductive liquid is made to cover a distance from the pipe 10. When the grinding wheel is being repaired, when the table 2 drives the tailstock 3 and the diamond pen 4 to move to one side of the grinding wheel, the push rod 24 moves to the side of the guide block 29. Before the diamond pen 4 contacts the grinding wheel, the push rod 24 contacts the guide block 29, so that the guide block 29 pushes the push rod 24. The moving push rod 24 drives the gear 23 to rotate, and the rotating gear 23 drives the stop shaft 12 to rotate, so that the stop shaft 12 rotates ninety degrees. At this time (such as Figure 6 ) The conductive liquid in the box body 7 can enter the pipe 10 through the perforation 13. When the grinding wheel is repaired normally, the table 2 moves at a uniform speed. If the machine tool creeps, the original motion state is changed. At this time, the counterweight 22 will not change much in the original motion state, and the motion state of the device is changed, which makes the counterweight 22 pull the elastic membrane 21, causing the elastic membrane 21 to deform. The liquid on one side of the box body 7 is squeezed by the counterweight 22 and the elastic membrane 21 and enters the pipe 10, causing the liquid level in one of the pipes 10 to rise. When the liquid level hits the guide rod 19, the circuit between the battery 16 and the alarm 20 is fully connected, causing the alarm 20 to sound an alarm, thereby reminding the operator that there is a creeping problem and to pay attention to re-repairing the grinding wheel. Until the grinding wheel is repaired, there is no creeping problem, which means that the grinding wheel is repaired without any problem and can be used. In this way, there is no need to weigh the amount of margin in the fine grinding stage, and the margin of super-fine grinding or mirror grinding can be minimized to improve efficiency, and there will be no risk of insufficient margin.

[0046] After the grinding wheel is repaired, when grinding the product, as the table 2 moves, one end of the push rod 24 will move out of the side of the guide block 29. At this time, the spring 26 will push the push rod 24 to reset. The reset push rod 24 drives the gear 23 and the stop shaft 12 to rotate and reset. After the stop shaft 12 is reset, the perforation 13 cannot connect the pipe 10 and the box body 7. At this time, even if the components in the box body 7 are affected by the inertia of the reversal of the table 2, the liquid in the box body 7 will not enter the pipe 10, increasing the liquid in the pipe 10, thereby avoiding the alarm 20 from giving a false alarm during normal grinding.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
