Description

Technical Field

[0001] This invention relates to the field of grinding equipment structure, and in particular to a grinding equipment for parts production and its usage method. Background Technology

[0002] Parts are the basic elements that make up a machine. They can be broadly divided into general-purpose parts and special-purpose parts. In addition, a combination of parts that work together is called a component or assembly. Some parts with high surface roughness are generally first rough-machined and then polished. When polishing the surface of a part, there are generally two methods: machine polishing and manual polishing.

[0003] In existing technologies, when manually polishing parts, it is generally necessary to control the amount of polishing per pass and perform multiple repeated polishing operations. However, the amount of polishing per pass is not easy to control and usually requires a lot of operating experience to judge. For unskilled workers, it is easy to make careless operation when manually polishing, resulting in excessive polishing per pass, causing over-polishing, scrapping of products, and certain inconveniences in production. Therefore, we disclose a polishing equipment for parts production and its usage method to meet people's needs. Summary of the Invention

[0004] The purpose of this application is to provide a grinding equipment and its usage method for parts production, in order to solve the problem mentioned in the background art that when manually grinding parts, it is generally necessary to control the amount of grinding per pass and perform multiple repeated grindings. However, the amount of grinding per pass is not easy to control and generally requires rich operating experience to judge. For unskilled workers, careless operation is prone to occur when performing manual grinding, resulting in excessive grinding per pass, over-grinding, product scrapping, and certain inconveniences in production.

[0005] To achieve the above objectives, this application provides the following technical solution: a grinding device for parts production, comprising a base plate, an L-shaped fixing frame mounted on the top side of the base plate, a sliding groove formed on one side of the L-shaped fixing frame, a clearance opening communicating with the sliding groove formed on one side of the L-shaped fixing frame, a sliding block slidably mounted in the sliding groove, a rotating hole formed on one side of the sliding block, a rotating shaft rotatably mounted in the rotating hole, a grinding disc sleeved on one end of the rotating shaft, the other end passing through the clearance opening and extending to one side of the L-shaped fixing frame, an elastic pushing unit mounted on one side of the sliding block, a motor fixedly mounted on one side of the L-shaped fixing frame by a bracket, transmission wheels sleeved on both the output shaft of the motor and the rotating shaft, transmission belts sleeved on the two transmission wheels, an outer cover mounted on one side of the L-shaped fixing frame, the outer cover being fitted over the outside of the grinding disc and exposing the lower half of the grinding disc.

[0006] Based on the above structure, during use, the motor drives the corresponding transmission wheel to rotate in a fixed direction. The transmission belt then drives the corresponding transmission wheel and rotating shaft to rotate, causing the grinding disc to rotate. The part is held close to the grinding disc, and the part is ground through the portion of the disc exposed above the outer cover. If the part is accidentally brought too close to the grinding disc, resulting in excessive grinding in a single pass, the pressure between the part and the grinding disc increases, leading to increased friction. Under the influence of this frictional force, the sliding block overcomes the thrust of the elastic push unit and slides along the groove. This reduces the distance between the rotating shaft and the motor's output shaft, causing the transmission belt to slip. The grinding disc then loses its driving force and stops rotating, thus stopping the grinding process and preventing over-grinding and damage to the part. When the part leaves the grinding disc, the sliding block resets under the action of the elastic push unit, and the grinding disc continues to rotate. This ensures that the part can only be ground with a small amount of material at a time, allowing the grinding to continue and controlling the amount of material ground in a single pass to prevent part damage.

[0007] Preferably, the elastic pushing unit includes a spring, and an adjustment component is installed on one side wall of the slide groove. One end of the spring is installed on one side of the sliding block, and the other end is installed on one side of the adjustment component.

[0008] Furthermore, by setting up the spring, the spring force pushes the sliding block to the side away from the motor, ensuring the distance between the rotating shaft and the output shaft of the motor, thereby ensuring the normal transmission of the transmission belt. When subjected to external force, the spring is squeezed, which allows the sliding block to move.

[0009] Preferably, the adjusting assembly includes a threaded rod, an clearance groove is provided on one side of the slide groove on the L-shaped fixing bracket, a threaded hole is provided on one side wall of the slide groove, the threaded rod is screwed into the threaded hole, and one end of the threaded rod abuts against one end of the spring.

[0010] Furthermore, by rotating the threaded rod, the length of one end of the threaded rod protruding from the groove wall can be adjusted, thereby adjusting the maximum gap between the threaded rod and the sliding block. This allows for adjustment of the spring compression and spring force, and ultimately, the maximum amount of material that can be ground in a single pass between the part and the grinding disc.

[0011] Preferably, a guide rod is installed on one side of the sliding block, the guide rod passes through the center of the spring, and a clearance hole is provided at one end of the threaded rod, the guide rod matching the clearance hole.

[0012] Furthermore, by setting the guide rod, the extension and retraction of the spring along the guide rod can be controlled to prevent abnormal deformation when compressed, which would affect the normal operation of the mechanism.

[0013] Preferably, a knob is installed on the end of the threaded rod away from the spring, and an identification unit is installed on one side of the threaded rod.

[0014] Furthermore, the knob design facilitates the rotation of the threaded rod, increasing ease of operation.

[0015] Preferably, the marking unit includes a scale, and a sliding hole is provided on one side wall of the groove. The scale is slidably installed in the sliding hole, and one end of the scale is connected to the threaded rod through a linkage unit.

[0016] Furthermore, by setting a scale, when the threaded rod is rotated, the scale moves synchronously along the sliding hole under the action of the linkage unit, so that the length of the threaded rod protruding from the groove wall can be read directly, which is convenient for adjustment.

[0017] Preferably, the linkage unit includes a rotating ring, and an annular groove is formed on the non-threaded section of the threaded rod near the knob end. The rotating ring is rotatably sleeved on the annular groove, and one side of the rotating ring is installed at one end of the scale.

[0018] Furthermore, by setting up a rotating ring, which is rotatably sleeved on the threaded rod, the movement can occur synchronously while the threaded rod rotates.

[0019] Preferably, a baffle is installed on one side of the L-shaped fixing frame, and the baffle is located on one side of the outer cover and the grinding disc.

[0020] Furthermore, the baffle can block the debris flying out with the grinding disc, thus providing protection.

[0021] Preferably, a collection box is installed on the top side of the substrate, the collection box is located below the polishing disc, and the collection box corresponds to the position of the baffle.

[0022] Furthermore, the collection box facilitates the collection of grinding debris for centralized processing.

[0023] A method of using a grinding equipment for parts manufacturing, the method comprising:

[0024] S1. In use, the motor drives the corresponding transmission wheel to rotate in a fixed direction, and the corresponding transmission wheel and rotating shaft rotate under the transmission of the transmission belt, which in turn causes the grinding disc to rotate. Hold the part close to the grinding disc and grind the part through the part of the grinding disc exposed outside the cover.

[0025] S2. When a part is accidentally brought too close to the grinding disc, resulting in excessive grinding in a single operation, the pressure between the part and the grinding disc increases, leading to increased friction. Under the influence of the frictional force, the sliding block overcomes the spring force and slides along the groove, thereby reducing the distance between the rotating shaft and the motor's output shaft and causing the transmission belt to slip. This causes the grinding disc to lose its driving force and stop rotating, thus stopping the grinding process and preventing the part from being over-ground and scrapped. When the part leaves the grinding disc, the sliding block returns to its original position under the action of the spring, and the grinding disc continues to rotate.

[0026] In summary, the technical effects and advantages of this invention are as follows: 1. In this invention, by setting a sliding block and a spring, when the single grinding amount is too large, the pressure between the part and the grinding disc increases, thus increasing the friction. This causes the sliding block to overcome the spring force and slide along the groove, thereby reducing the distance between the rotating shaft and the output shaft of the motor and causing the transmission belt to slip. This causes the grinding disc to lose its driving force and stop rotating, thus stopping the grinding. This ensures that the part can only be ground with a small amount of grinding between it and the grinding disc, allowing the grinding to continue, thereby controlling the single grinding amount and preventing the part from being scrapped. 2. In this invention, by setting a threaded rod, rotating the threaded rod can adjust the length of one end protruding from the groove wall, thereby adjusting the maximum gap between the threaded rod and the sliding block. This allows adjustment of the spring compression and spring force, thereby adjusting the maximum single grinding amount between the part and the grinding disc. The knob facilitates the rotation of the threaded rod, increasing operational convenience. 3. In this invention, by setting a scale, when the threaded rod is rotated, the scale moves synchronously along the sliding hole under the action of the linkage unit, so that the length of the threaded rod protruding from the groove wall can be read directly, which is convenient for adjustment. By setting a guide rod, the spring can be controlled to extend and retract along the guide rod to prevent abnormal deformation when squeezed, which would affect the normal operation of the mechanism. By setting a collection box, it is convenient to collect the grinding debris and make it convenient for centralized processing. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example: Reference Figure 1-6 The polishing equipment for manufacturing parts shown includes a base plate 1. An L-shaped fixing frame 2 is mounted on the top side of the base plate 1. A groove 17 is provided on one side of the L-shaped fixing frame 2. An clearance opening 8 communicating with the groove 17 is provided on one side of the L-shaped fixing frame 2. A sliding block 14 is slidably installed in the groove 17. A rotating hole is provided on one side of the sliding block 14. A rotating shaft 9 is rotatably installed in the rotating hole. A polishing disc 4 is sleeved on one end of the rotating shaft 9. The other end passes through the clearance opening 8 and extends to one side of the L-shaped fixing frame 2. An elastic pushing unit is installed on one side of the sliding block 14. A motor 13 is fixedly installed on one side of the L-shaped fixing frame 2 by a bracket 12. A transmission wheel 10 is sleeved on both the output shaft of the motor 13 and the rotating shaft 9. A transmission belt 11 is sleeved on the two transmission wheels 10. An outer cover 5 is installed on one side of the L-shaped fixing frame 2. The outer cover 5 is sleeved on the outside of the polishing disc 4 and exposes the lower half of the polishing disc 4.

[0037] Based on the above structure, during use, the motor 13 drives the corresponding transmission wheel 10 to rotate in a fixed direction, and under the transmission of the transmission belt 11, the corresponding transmission wheel 10 and the rotating shaft 9 rotate, causing the grinding disc 4 to rotate. The part is held close to the grinding disc 4, and the part is ground by the part of the grinding disc 4 exposed outside the outer cover 5. If the part is accidentally brought too close to the grinding disc 4, resulting in an excessive amount of grinding in a single operation, the pressure between the part and the grinding disc 4 increases, thus increasing the friction. At this time, under the action of the component force of friction, the sliding block 14 will overcome the elastic push single force. The part slides along the slide groove 17 due to the thrust of the element, thereby reducing the distance between the rotating shaft 9 and the output shaft of the motor 13 and causing the transmission belt 11 to slip, thereby causing the grinding disc 4 to lose its driving force and stop rotating, thus stopping the grinding and preventing the part from being over-grinded and scrapped. When the part leaves the grinding disc 4, the sliding block 14 is reset under the action of the elastic push unit, and the grinding disc 4 continues to rotate, so that the part can only be ground with a small amount of grinding between it and the grinding disc 4, so that the grinding can continue, thereby controlling the amount of grinding per time and preventing the part from being scrapped.

[0038] like Figure 4 As shown, the elastic pushing unit includes a spring 15. An adjustment component is installed on one side of the groove wall of the slide 17. One end of the spring 15 is installed on one side of the sliding block 14, and the other end is installed on one side of the adjustment component. Through the setting of the spring 15, the elastic force of the spring 15 pushes the sliding block 14 to the side away from the motor 13, ensuring the distance between the rotating shaft 9 and the output shaft of the motor 13, thereby ensuring the normal transmission of the transmission belt 11. When subjected to external force, the spring 15 is squeezed, thereby allowing the sliding block 14 to move.

[0039] like Figure 4 and 5 As shown, the adjustment assembly includes a threaded rod 19. An clearance groove 3 is provided on one side of the slide groove 17 on the L-shaped fixing bracket 2. A threaded hole is provided on one side wall of the slide groove 17. The threaded rod 19 is screwed into the threaded hole. One end of the threaded rod 19 abuts against one end of the spring 15. By rotating the threaded rod 19, the length of one end of the threaded rod 19 protruding from the slide groove 17 wall can be adjusted, thereby adjusting the maximum gap between the threaded rod 19 and the sliding block 14. This allows adjustment of the compression of the spring 15 and the elasticity of the spring 15, thereby adjusting the maximum single grinding amount between the part and the grinding disc 4.

[0040] like Figure 4 and 5 As shown, a guide rod 16 is installed on one side of the sliding block 14. The guide rod 16 passes through the center of the spring 15. One end of the threaded rod 19 is provided with a clearance hole 21. The guide rod 16 matches the clearance hole 21. By setting the guide rod 16, the spring 15 can be controlled to extend and retract along the guide rod 16 to prevent abnormal deformation when squeezed, which would affect the normal operation of the mechanism.

[0041] like Figure 5 As shown, a knob 20 is installed on the end of the threaded rod 19 away from the spring 15, and an identification unit is installed on one side of the threaded rod 19. The knob 20 facilitates the rotation of the threaded rod 19 and increases the ease of operation.

[0042] like Figure 5 As shown, the marking unit includes a scale 18. A sliding hole is provided on one side of the groove wall of the slide 17. The scale 18 is slidably installed in the sliding hole. One end of the scale 18 is connected to the threaded rod 19 through a linkage unit. With the setting of the scale 18, when the threaded rod 19 is rotated, the scale 18 moves synchronously along the sliding hole under the action of the linkage unit, so that the length of the threaded rod 19 protruding from the groove wall of the slide 17 can be read directly, which is convenient for adjustment.

[0043] like Figure 5 and 6 As shown, the linkage unit includes a rotating ring 22. An annular groove 23 is provided on the non-threaded section of the threaded rod 19 near the knob 20. The rotating ring 22 is rotatably sleeved on the annular groove 23. One side of the rotating ring 22 is installed on one end of the scale 18. By setting the rotating ring 22, the rotating ring 22 is rotatably sleeved on the threaded rod 19, so that it can move synchronously while the threaded rod 19 rotates.

[0044] like Figure 1 As shown, a baffle 6 is installed on one side of the L-shaped fixing frame 2. The baffle 6 is located on one side of the outer cover 5 and the grinding disc 4. By setting the baffle 6, the baffle 6 can block the debris flying out with the grinding disc 4 and play a protective role.

[0045] like Figure 1 As shown, a collection box 7 is installed on the top side of the substrate 1. The collection box 7 is located below the grinding disc 4. The collection box 7 corresponds to the position of the baffle 6. The collection box 7 facilitates the collection of grinding debris and makes it easy to process it centrally.

[0046] A method of using a grinding equipment for parts manufacturing, the method comprising:

[0047] S1. In use, the motor 13 drives the corresponding transmission wheel 10 to rotate in a fixed direction, and the transmission belt 11 drives the corresponding transmission wheel 10 and the rotating shaft 9 to rotate, and the grinding disc 4 to rotate. Hold the part close to the grinding disc 4, and grind the part through the part of the grinding disc 4 exposed outside the cover 5.

[0048] S2. When the part is accidentally brought too close to the grinding disc 4, resulting in excessive grinding in a single operation, the pressure between the part and the grinding disc 4 increases, which in turn increases the friction. At this time, under the action of the component force of the friction, the sliding block 14 will overcome the elastic force of the spring 15 and slide along the slide groove 17, thereby reducing the distance between the rotating shaft 9 and the output shaft of the motor 13 and causing the transmission belt 11 to slip. This causes the grinding disc 4 to lose its driving force and stop rotating, thus stopping the grinding and preventing the part from being over-grinded and scrapped. When the part leaves the grinding disc 4, the sliding block 14 is reset under the action of the spring 15, and the grinding disc 4 continues to rotate.

[0049] Working principle of this invention: In use, the motor 13 drives the corresponding transmission wheel 10 to rotate in a fixed direction, and under the transmission of the transmission belt 11, the corresponding transmission wheel 10 and the rotating shaft 9 rotate, causing the grinding disc 4 to rotate. The part is held close to the grinding disc 4, and the part is ground by the part of the grinding disc 4 exposed outside the outer cover 5. If the part is accidentally brought too close to the grinding disc 4, resulting in excessive grinding in a single operation, the pressure between the part and the grinding disc 4 increases, thus increasing the friction. At this time, under the action of the component force of friction, the sliding block 14 will overcome the spring. The spring 15 causes the sliding block 14 to slide along the groove 17, thereby reducing the distance between the rotating shaft 9 and the output shaft of the motor 13 and causing the transmission belt 11 to slip. This causes the grinding disc 4 to lose its driving force and stop rotating, thus stopping the grinding and preventing the parts from being over-grinded and scrapped. When the parts leave the grinding disc 4, the sliding block 14 is reset under the action of the spring 15, and the grinding disc 4 continues to rotate. This ensures that the parts can only be ground with a small amount of grinding between them and the grinding disc 4, so that the grinding can continue. This controls the amount of grinding per cycle and prevents the parts from being scrapped.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
