Description

Technical Field

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

[0002] In modern automotive industry, as an important part of the braking system, the brake disc plays a crucial role. It achieves vehicle deceleration or stop through the contact of friction materials (brake pads). Therefore, the surface quality, dimensional accuracy and thermal stability of the brake disc are directly related to the braking performance and safety of the vehicle. With the continuous progress of automotive technology, the performance requirements for brake discs are getting higher and higher, which is not only reflected in their materials and structural designs, but also in the refined management of their production processes. The production of brake discs involves multiple processes, and the grinding process is particularly critical. Grinding can not only remove burrs, oxide layers and other surface defects generated during the casting or processing of brake discs, but also improve the flatness and roughness of the brake discs, ensuring effective and uniform friction between the brake discs and brake pads during use. Therefore, the quality of grinding directly affects the overall performance and lifespan of the brake discs.

[0003] However, there are some deficiencies in the application of existing brake disc grinding tools. 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 adjustment of equipment during the grinding process, increasing the production preparation time and labor intensity. On the other hand, these tools have insufficient control over the workpiece during the grinding process, easily causing excessive or insufficient grinding, affecting the surface quality and service life of the brake discs. In addition, existing grinding tools also have defects in heat dissipation. The heat generated during the grinding process is not easily discharged quickly, which may cause local overheating of the brake discs, thereby affecting their material properties and dimensional stability. Moreover, when simply fixing the brake discs, workers need to perform multiple layers of socketing to install the brake discs on the grinding lathe, which is rather troublesome. And generally, the clamping tools have fewer fixing surfaces for the brake discs and cannot fix the brake discs from all directions, which may cause some displacement of the brake discs during high-speed rotation, affecting the grinding accuracy. For this reason, an adjustable grinding frame for brake disc production is needed to solve the existing deficiencies. Summary of the Invention

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art and provide an adjustable grinding frame for brake disc production. By setting the limiting component, the guiding piece is driven to move along the radial direction of the cylinder part, thereby pushing the limiting piece to move synchronously until the outer side of the limiting piece abuts against the inner wall of the shaft hole of the convex part, so that the axis of the convex part coincides with the axis of the adjusting cylinder, enabling the workpiece to quickly maintain a stable position; by setting the air guiding piece, it is possible to avoid the temperature of the workpiece rising during the grinding process, thereby preventing the surface of the workpiece from deforming due to excessive temperature, and at the same time facilitating blowing away the generated debris from the surface of the workpiece; by setting the adjusting component, on the one hand, the heat dissipation pipe can dissipate heat from the workpiece by blowing air, and on the other hand, it is beneficial to fix the main body part of the workpiece by using its own structure, so that the workpiece remains stable during high-speed rotation.

[0015] Advantageous effects:

[0016] Compared with the prior art, the adjustable grinding frame for brake disc production has the following advantageous effects:

[0017] 1. In the present invention, through the provided limiting component, when the adjusting cylinder is rotated, since the adjusting cylinder is threadedly connected to the moving ring and the guiding block is movably connected to the cylinder member, the two moving rings approach each other, driving the first connecting rod to rotate. The angle between the first connecting rods gradually decreases, driving the guiding piece to move radially along the cylinder member, thereby pushing the limiting piece to move synchronously until the outer side of the limiting piece abuts against the inner wall of the shaft hole of the convex portion, making the axis of the convex portion coincide with the axis of the adjusting cylinder, and enabling the workpiece to quickly maintain a stable position.

[0018] 2. In the present invention, through the provided air guiding member, part of the heat dissipation holes communicates with the inner heat dissipation grooves of the main body portion, and the other part communicates with the outside of the main body portion, so that part of the air is blown out from the heat dissipation grooves, and the other part of the air is blown out along the surface of the main body portion, cooling the workpiece during the grinding process, avoiding the temperature of the workpiece from rising during the grinding process, thus preventing the surface of the workpiece from deforming due to excessive temperature, and at the same time facilitating blowing away the generated debris from the surface of the workpiece.

[0019] 3. In the present invention, through the provided adjusting component, when the servo motor is started, it drives the driving rod to rotate. Since the driving rod is threadedly connected to the guiding ring and the supporting rod restricts the moving direction of the guiding ring, the guiding ring moves closer to the accommodating bin, causing the second connecting rod to rotate, thereby pushing the moving tube to move outward along the air guiding tube until the outer side of the heat dissipation tube abuts against the inner side of the main body portion. On the one hand, the heat dissipation tube can dissipate heat from the workpiece by blowing air, and on the other hand, it is beneficial to fix the main body portion of the workpiece by using its own structure, enabling the workpiece to remain stable during high-speed rotation.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Such as Figures 1-11As shown in the figure, the present invention provides a technical solution: an adjustable grinding frame for brake disc production, including a workpiece 1 and a mounting member 2. The workpiece 1 includes a convex portion 101 and a main body portion 102, and the convex portion 101 and the main body portion 102 are integrally formed. The mounting member 2 includes a cylindrical member 201, a support rod 202 and a wind guiding member. The tail end of the support rod 202 is connected to a control mechanism, and a cutter is located on one side of the workpiece 1. The support rod 202 is driven to rotate by the control mechanism, so that the workpiece 1 rotates at a high speed, and the surface of the workpiece 1 is ground by the feeding method of the cutter. The cylindrical member 201 penetrates through the convex portion 101. A first limiting cover 3 is fixedly connected to the outer side of the cylindrical member 201, and a second limiting cover 4 is slidably connected to the outer side of the cylindrical member 201. The convex portion 101 is located on the opposite side of the first limiting cover 3 and the second limiting cover 4. Both the first limiting cover 3 and the second limiting cover are of a hollow structure, which is convenient for the heat generated during the grinding process to dissipate. A limiting component 5 is arranged on the cylindrical member 201. The limiting component 5 is located on the opposite side of the first limiting cover 3 and the second limiting cover 4, and the limiting component 5 is movably connected to the inner wall of the convex portion 101. Several heat dissipation components 6 are movably connected to the wind guiding member. The heat dissipation components 6 are arranged in a circular array, and the outer sides of the heat dissipation components 6 are all movably connected to the inner wall of the main body portion 102. An adjusting component 7 is arranged on the support rod 202, and the adjusting component 7 is fixedly connected to the heat dissipation component 6.

[0035] As Figure 1 , Figure 4 , Figure 8 and Figure 9 As shown in the figure, the limiting component 5 includes a moving ring 501, a guiding block 502, a first connecting rod 503, a limiting piece 504 and a guiding piece 505. The moving rings 501 are symmetrically arranged. Several guiding blocks 502 are fixedly connected to the outer sides of the moving rings 501, and the guiding blocks 502 are arranged in a circular array to limit the moving direction of the moving rings 501. The limiting pieces 504 are located on the opposite sides of the moving rings 501, and the limiting pieces 504 are arranged in a circular array. The outer sides of the limiting pieces 504 are in contact with the inner side of the convex portion 101. Guiding pieces 505 are fixedly connected to the inner sides of the limiting pieces 504, which helps to control the moving direction of the limiting pieces 504, so that the limiting pieces 504 move radially along the cylindrical member 201. The outer sides of the limiting pieces 504 are in fit with the inner side of the shaft hole of the convex portion 101, and multiple grooves are arranged on the surfaces of the limiting pieces 504 to increase the friction between the limiting pieces 504 and the shaft hole of the convex portion 101. Both sides of the guiding piece 505 are movably connected to the first connecting rod 503 through rotating shafts, and the other ends of the first connecting rods 503 are respectively movably connected to the outer sides of the guiding blocks 502 through rotating shafts.

[0036] As Figure 1 , Figure 4 , Figure 8 and Figure 9As shown, the moving ring 501 and the guiding block 502 are both movably connected to the inside of the cylinder 201. One end of the guiding piece 505 away from the limiting piece 504 is movably connected to the inside of the cylinder 201. An adjusting cylinder 8 is movably connected to the inside of the cylinder 201. A set of symmetric threads are provided on the outer side of the adjusting cylinder 8. The adjusting cylinder 8 penetrates through the moving ring 501 and is threadedly connected to the moving ring 501.

[0037] Rotate the adjusting cylinder 8. Since the adjusting cylinder 8 is threadedly connected to the moving ring 501 and the guiding block 502 is movably connected to the cylinder 201, the two moving rings 501 approach each other, driving the first connecting rod 503 to rotate. The included angle between the first connecting rods 503 gradually decreases, driving the guiding piece 505 to move radially along the cylinder 201, thereby pushing the limiting piece 504 to move synchronously until the outer side of the limiting piece 504 abuts against the inner wall of the shaft hole of the convex portion 101, making the axis of the convex portion 101 coincide with the axis of the adjusting cylinder 8, so that the workpiece 1 quickly maintains a stable position.

[0038] As Figure 1 、 Figure 7 and Figure 10 shown, several sliding grooves 9 are provided on the outer side of one end of the cylinder 201. Several connecting blocks 10 are fixedly connected to the inner side of the limiting cover two 4. The connecting blocks 10 and the sliding grooves 9 are both distributed in a circular array, and the connecting blocks 10 are respectively slidably connected to the sliding grooves 9. A limiting cylinder 11 is threadedly connected to one end of the cylinder 201, and one end of the limiting cylinder 11 abuts against the outer side of the limiting cover two 4.

[0039] Through the cooperation of the connecting block 10 and the sliding groove 9, the moving direction of the limiting cover two 4 is kept fixed, and the cooperation of the limiting cover one 3 and the limiting cover two 4 is beneficial to enhancing the stability of the convex portion 101 and preventing the workpiece 1 from vibrating and deviating along the axial direction of the adjusting cylinder 8.

[0040] As Figure 1 、 Figure 6 and Figure 11As shown, the air guiding member includes a receiving bin 203, an air guiding pipe 204, and a centrifugal fan 205. The air guiding pipes 204 are distributed in a circular array. The air guiding pipes 204 are all fixedly connected to the outside of the receiving bin 203, and the centrifugal fan 205 is fixedly connected to the inside of the receiving bin 203. The cylindrical member 201 is fixedly connected to one side of the receiving bin 203, and the support rod 202 is fixedly connected to the other side of the receiving bin 203. The inside of the adjusting cylinder 8, the inside of the receiving bin 203, and the inside of the air guiding pipe 204 are sequentially communicated. The heat dissipating member 6 includes a moving pipe 601 and a heat dissipating pipe 602. The moving pipes 601 are distributed in a circular array. The moving pipes 601 are respectively movably connected to the outside of the air guiding pipes 204, and the other ends of the moving pipes 601 are all fixedly connected with heat dissipating pipes 602. A plurality of heat dissipation holes 12 are formed on the outside of the heat dissipating pipe 602, and the outside of the heat dissipating pipe 602 abuts against the inside of the main body portion 102. The inside of the air guiding pipe 204, the inside of the moving pipe 601, and the inside of the heat dissipating pipe 602 are sequentially connected and communicated.

[0041] When the centrifugal fan 205 is started, the wind enters the inside of the receiving bin 203 along the axis of the adjusting cylinder 8. Under the action of the centrifugal fan 205, the wind moves radially along the receiving bin 203 into the inside of the four air guiding pipes 204, and enters the inside of the moving pipe 601 and the heat dissipating pipe 602 along the air guiding pipes 204, and finally blows out from the heat dissipation holes 12. Since the heat dissipating pipe 602 abuts against the inside of the main body portion 102, part of the heat dissipation holes 12 communicates with the heat dissipation grooves on the inside of the main body portion 102, and the other part communicates with the outside of the main body portion 102, so that part of the wind blows out from the heat dissipation grooves, and the other part of the wind blows out along the surface of the main body portion 102, cooling the workpiece 1 during the grinding process, avoiding the temperature rise of the workpiece 1 during the grinding process, thereby avoiding the deformation of the surface of the workpiece 1 caused by too high temperature, and at the same time facilitating blowing away the generated debris from the surface of the workpiece 1 by blowing.

[0042] As Figure 1 and Figure 10 shown, the adjusting assembly 7 includes a second connecting rod 701, a guiding ring 702, and a driving rod 703. Threads are provided on the outside of the driving rod 703. The driving rod 703 penetrates through the axis of the guiding ring 702, and the driving rod 703 is threadedly connected to the guiding ring 702. The outside of the guiding ring 702 is movably connected with a plurality of second connecting rods 701 through a rotating shaft. The second connecting rods 701 are distributed in a circular array. The other ends of the second connecting rods 701 are respectively movably connected to the outside of the moving pipe 601 through a rotating shaft. The driving rod 703 is movably connected to the outside of the support rod 202 through a bearing. The support rod 202 penetrates through the guiding ring 702, and the support rod 202 is movably connected to the guiding ring 702. A servo motor 13 is fixedly connected to the inside of the support rod 202, 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 drive rod 703 to rotate. Since the drive rod 703 is threadedly connected to the guide ring 702 and the support rod 202 restricts the movement direction of the guide ring 702, the guide ring 702 moves closer to the accommodation chamber 203, causing the second connecting rod 701 to rotate, thereby pushing the moving pipe 601 to move outward along the air duct 204 until the outer side of the heat dissipation pipe 602 abuts against the inner side of the main body portion 102. On the one hand, the heat dissipation pipe 602 can dissipate heat from the workpiece 1 by blowing air, and on the other hand, it is beneficial to fix the main body portion 102 of the workpiece 1 by using its own structure, 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 outside of the mounting member 2, so that the convex portion 101 is sleeved on the outside of the cylindrical member 201, and the inner side of the convex portion 101 abuts against the first limiting cover 3. Subsequently, by aligning the connecting blocks 10 with the sliding grooves 9 respectively, the second limiting cover 4 is slidably connected to the outside of the cylindrical member 201, and the second limiting cover 4 abuts against the outside of the convex portion 101. Then, the limiting cylinder 11 is threadedly connected to the outside of the cylindrical member 201. Then, the adjusting cylinder 8 is rotated. Since the adjusting cylinder 8 is threadedly connected to the moving ring 501 and the guiding block 502 is movably connected to the cylindrical member 201, the two moving rings 501 approach each other, driving the first connecting rod 503 to rotate. The included angle between the first connecting rods 503 gradually decreases, driving the guiding piece 505 to move along the radial direction of the cylindrical member 201, thereby pushing the limiting piece 504 to move synchronously until the outside of the limiting piece 504 abuts against the inner wall of the axial hole of the convex portion 101. Finally, the limiting cylinder 11 is rotated towards the convex portion 101 so that the end of the limiting cylinder 11 abuts against the outside of the limiting cover, thereby limiting the position of the convex portion 101 through the first limiting cover 3, the second limiting cover 4 and the limiting piece 504; The servo motor 13 is started to drive the driving rod 703 to rotate. Since the driving rod 703 is threadedly connected to the guiding ring 702 and the supporting rod 202 limits the moving direction of the guiding ring 702, the guiding ring 702 moves towards the accommodating chamber 203, causing the second connecting rod 701 to rotate, thereby pushing the moving pipe 601 to move outward along the air duct 204 until the outside of the heat dissipation pipe 602 abuts against the inner side of the main body portion 102. The tail end of the supporting rod 202 is connected to the control mechanism, and the cutting tool is located on one side of the workpiece 1. The supporting rod 202 is driven to rotate through the control mechanism, so that the workpiece 1 rotates at a high speed, and the surface of the workpiece 1 is polished by the feeding method of the cutting tool. During this process, the centrifugal fan 205 is started, and the air enters the inside of the accommodating chamber 203 along the axis of the adjusting cylinder 8. Under the action of the centrifugal fan 205, the air moves along the radial direction of the accommodating chamber 203 into the four air ducts 204, and enters the inside of the moving pipe 601 and the heat dissipation pipe 602 along the air duct 204, and finally blows out from the heat dissipation holes 12. Since the heat dissipation pipe 602 abuts against the inner side of the main body portion 102, part of the heat dissipation holes 12 communicate with the heat dissipation grooves on the inner side of the main body portion 102, and the other part communicates with the outside of the main body portion 102, so that part of the air blows out from the heat dissipation grooves, and the other part of the air blows out along the surface of the main body portion 102, cooling the workpiece 1 during the polishing process.
