Description

Technical Field

[0001] The invention relates to the technical field of brake disc grinding, in particular to an adjustable grinding frame for brake disc production. Background Art

[0002] In the modern automobile industry, brake discs are an important part of the braking system and play a vital role. They slow down or stop the vehicle through the contact of friction materials (brake pads). Therefore, the surface quality, dimensional accuracy and thermal stability of brake discs are directly related to the braking performance and safety of the vehicle. With the continuous advancement of automobile technology, the performance requirements for brake discs are getting higher and higher. This is not only reflected in their material and structural design, but also in the refined management of their production process. The production of brake discs involves multiple links, among which the grinding process is particularly critical. Grinding can not only remove burrs, oxide layers and other surface defects generated by the brake disc during casting or processing, but also improve the flatness and roughness of the brake disc, ensuring that it can achieve effective and uniform friction with the brake pad during use. Therefore, the quality of grinding directly affects the overall performance and life of the brake disc.

[0003] However, the existing brake disc grinding tools have some shortcomings in application. On the one hand, traditional grinding tools often lack flexibility and are difficult to adapt to brake discs of different sizes and models, resulting in frequent equipment adjustment during the grinding process, which increases production preparation time and labor intensity. On the other hand, these tools do not have precise control over the workpiece during the grinding process, which can easily cause excessive or insufficient grinding, affecting the surface quality and service life of the brake disc. In addition, the existing grinding tools also have defects in heat dissipation. The heat generated during the grinding process is not easy to be discharged quickly, which may cause local overheating of the brake disc, thereby affecting its material properties and dimensional stability. In addition, when simply fixing the brake disc, the staff needs to perform multi-layer socketing to install the brake disc on the grinding lathe, which is more troublesome to operate. In addition, the general clamping tool has less fixing surface for the brake disc and cannot fix the brake disc from all directions. The brake disc may be slightly displaced during high-speed rotation, affecting the grinding accuracy. For this reason, an adjustable grinding rack for brake disc production is needed to solve the existing shortcomings. Summary of the invention

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art and to provide an adjustable grinding frame for brake disc production.

[0017] 1. The present invention uses a limit assembly to rotate the adjusting cylinder.

[0035] like Figure 1 , Figure 4 , Figure 8 and Fig. 9 As shown, the limiting assembly 5 includes a moving ring 501, a guide block 502, a connecting rod 503, a limiting piece 504 and a guide piece 505. The moving ring 501 is symmetrically arranged. The outer side of the moving ring 501 is fixedly connected with a plurality of guide blocks 502, and the guide blocks 502 are arranged in a circular array to limit the moving direction of the moving ring 501. The limiting piece 504 is located on the opposite side of the moving ring 501, and the limiting piece 504 is arranged in a circular array. The outer side of the limiting piece 504 conflicts with the inner side of the protrusion 101, and the inner side of the limiting piece 504 The two sides are fixedly connected with guide plates 505, which help to control the moving direction of the limiting plate 504 so that the limiting plate 504 moves radially along the cylinder 201. The outer side of the limiting plate 504 fits with the inner side of the axial hole of the protrusion 101, and the surface of the limiting plate 504 is provided with a plurality of grooves for increasing the friction between the limiting plate 504 and the axial hole of the protrusion 101. Both sides of the guide plate 505 are movably connected with connecting rods 503 through rotating shafts, and the other ends of the connecting rods 503 are movably connected to the outer sides of the guide blocks 502 through rotating shafts.

[0036] like Figure 1 , Figure 4 , Figure 8 and Fig. 9As shown, the movable ring 501 and the guide block 502 are both movably connected to the interior of the cylinder 201, and the end of the guide plate 505 away from the limiting plate 504 is movably connected to the interior of the cylinder 201.

The adjusting cylinder 8 passes through the movable ring 501, and the adjusting cylinder 8 is threadedly connected to the movable ring 501.

[0037] Rotate the adjusting cylinder 8. Since the adjusting cylinder 8 is threadedly connected to the moving ring 501, and the guide block 502 is movably connected to the cylinder 201, the two moving rings 501 are brought close to each other, driving the connecting rod 503 to rotate. The angle between the connecting rods 503 gradually decreases, driving the guide piece 505 to move along the radial direction of the cylinder 201, thereby pushing the limiting piece 504 to move synchronously until the outer side of the limiting piece 504 contacts the inner wall of the axial hole of the protrusion 101, so that the axis of the protrusion 101 coincides with the axis of the adjusting cylinder 8, so that the workpiece 1 can quickly maintain a stable position.

[0038] like Figure 1 , Figure 7 and Fig.10 As shown, a plurality of slide grooves 9 are provided on the outer side of one end of the cylinder 201, and a plurality of connecting blocks 10 are fixedly connected to the inner side of the limiting cover 2 4. The connecting blocks 10 and the slide grooves 9 are distributed in a circular array, and the connecting blocks 10 are slidingly connected to the slide grooves 9 respectively. A limiting cylinder 11 is threadedly connected to one end of the cylinder 201, and one end of the limiting cylinder 11 is in conflict with the outer side of the limiting cover 2 4.

[0039] By cooperating with the connecting block 10 and the slide groove 9, the moving direction of the limit cover 2 4 remains fixed, and the cooperation between the limit cover 1 3 and the limit cover 2 4 is beneficial to enhance the stability of the protrusion 101 and avoid vibration deviation of the workpiece 1 along the axial direction of the adjustment cylinder 8.

[0040] like Figure 1 , Figure 6 and Fig.11As shown, the air guide member includes a storage bin 203, an air guide duct 204 and a centrifugal fan 205. The air guide ducts 204 are distributed in a circular array. The air guide ducts 204 are all fixedly connected to the outside of the storage bin 203, and the centrifugal fan 205 is fixedly connected to the inside of the storage bin 203. The cylinder 201 is fixedly connected to one side of the storage bin 203, and the support rod 202 is fixedly connected to the other side of the storage bin 203. The inside of the adjustment cylinder 8, the inside of the storage bin 203 and the inside of the air guide duct 204 are respectively The heat sink 6 includes a movable tube 601 and a heat dissipation tube 602. The movable tubes 601 are distributed in a circular array. The movable tubes 601 are movably connected to the outside of the air duct 204, and the other ends of the movable tubes 601 are fixedly connected to the heat dissipation tube 602. A plurality of heat dissipation holes 12 are provided on the outside of the heat dissipation tube 602, and the outside of the heat dissipation tube 602 is in conflict with the inside of the main body 102. The inside of the air duct 204, the inside of the movable tube 601 and the inside of the heat dissipation tube 602 are sequentially connected.

[0041] The centrifugal fan 205 is started, and the wind enters the interior of the containing chamber 203 along the axis of the regulating tube 8. Under the action of the centrifugal fan 205, the wind moves radially along the containing chamber 203 to the interior of the four air ducts 204, and enters the interior of the moving tube 601 and the heat dissipation tube 602 along the air duct 204, and finally blows out from the heat dissipation hole 12. Since the heat dissipation tube 602 conflicts with the inner side of the main body 102, part of the heat dissipation hole 12 is connected with the inner heat dissipation groove of the main body 102, and the other part is connected with the outer side of the main body 102, so that part of the wind is blown out from the heat dissipation groove, and the other part of the wind is blown out from the main body 102 along its surface, so as to cool the workpiece 1 during the grinding process, avoid the temperature increase of the workpiece 1 during the grinding process, thereby avoiding deformation of the surface of the workpiece 1 caused by excessive temperature, and at the same time, it is beneficial to blow the generated debris away from the surface of the workpiece 1 by blowing.

[0042] like Figure 1 and Fig.10 As shown, the adjustment component 7 includes a connecting rod 2 701, a guide ring 702 and a driving rod 703. The outer side of the driving rod 703 is provided with a thread. The driving rod 703 passes through the axis of the guide ring 702 and is threadedly connected to the guide ring 702. The outer side of the guide ring 702 is movably connected with several connecting rods 2 701 through a rotating shaft. The connecting rods 2 701 are distributed in a circular array. The other ends of the connecting rods 2 701 are movably connected to the outer side of the moving tube 601 through a rotating shaft. The driving rod 703 is movably connected to the outer side of the support rod 202 through a bearing. The support rod 202 passes through the guide ring 702 and is movably connected to the guide ring 702. The support rod 202 is fixedly connected to a servo motor 13 inside, and the output end of the servo motor 13 is fixedly connected to one end of the driving rod 703.

[0043] Start the servo motor 13 to drive the driving rod 703 to rotate. Since the driving rod 703 is threadedly connected to the guide ring 702, the support rod 202 limits the movement direction of the guide ring 702, so that the guide ring 702 moves close to the accommodating bin 203, causing the connecting rod 2 701 to rotate, thereby pushing the moving tube 601 to move outward along the air guide tube 204 until the outer side of the heat dissipation tube 602 conflicts with the inner side of the main body 102. On the one hand, the heat dissipation tube 602 can dissipate the heat to the workpiece 1 by blowing air, and on the other hand, it is beneficial to use its own structure to fix the main body 102 of the workpiece 1, so that the workpiece 1 remains stable during high-speed rotation.

[0044] Working principle: When in use, first, the workpiece 1 is sleeved on the outer side of the mounting member 2, so that the raised portion 101 is sleeved on the outer side of the cylinder 201, and the inner side of the raised portion 101 conflicts with the limit cover 1 3. Subsequently, by aligning the connecting blocks 10 with the slide grooves 9 respectively, the limit cover 2 4 is slidably connected to the outer side of the cylinder 201, and the limit cover 2 4 conflicts with the outer side of the raised portion 101. Then, the limit cylinder 11 is threadedly connected to the outer side of the cylinder 201, and then the adjusting cylinder 8 is rotated. Since the adjusting cylinder 8 is threadedly connected to the moving ring 501, the guide block 502 is movably connected to the cylinder 201, so that the two moving rings 501 are close to each other. The servo motor 13 is started to drive the driving rod 703 to rotate, and the angle between the driving rod 703 and the guide ring 702 is gradually reduced, which drives the guide plate 505 to move along the radial direction of the cylinder 201, thereby pushing the limiting plate 504 to move synchronously until the outer side of the limiting plate 504 conflicts with the inner wall of the axial hole of the protrusion 101, and finally, the limiting cylinder 11 is rotated toward the protrusion 101, so that the end of the limiting cylinder 11 conflicts with the outer side of the limiting cover, thereby limiting the position of the protrusion 101 through the limiting cover 3, the limiting cover 4 and the limiting plate 504; the servo motor 13 is started to drive the driving rod 703 to rotate, and the driving rod 703 is threadedly connected with the guide ring 702. Then, the support rod 202 limits the movable direction of the guide ring 702, so that the guide ring 702 moves close to the storage bin 203, so that the second connecting rod 701 rotates, thereby pushing the moving tube 601 to move outward along the air guide tube 204 until the outer side of the heat dissipation tube 602 conflicts with the inner side of the main body 102. The tail end of the support rod 202 is connected to the control mechanism, and the cutter is located on one side of the workpiece 1. The control mechanism drives the support rod 202 to rotate, so that the workpiece 1 rotates at a high speed, and the surface of the workpiece 1 is polished by the cutter feeding method. In this process, the centrifugal fan 205 is started, and the wind is blown along the axis of the regulating cylinder 8. The wind enters the interior of the containing chamber 203, and under the action of the centrifugal fan 205, the wind moves radially along the containing chamber 203 to the interior of the four air ducts 204, and enters the interior of the moving tube 601 and the heat dissipation tube 602 along the air duct 204, and finally blows out from the heat dissipation hole 12. Since the heat dissipation tube 602 conflicts with the inner side of the main body 102, part of the heat dissipation hole 12 is connected with the inner heat dissipation groove of the main body 102, and the other part is connected with the outer side of the main body 102, so that part of the wind is blown out from the heat dissipation groove, and the other part of the wind is blown out from the main body 102 along its surface, so as to cool the workpiece 1 during the grinding process.
