Description

Technical Field

[0001] This utility model relates to a vehicle fixture, specifically a brake disc grinding and testing fixture for mounting various brake discs for grinding and testing as needed. Background Technology

[0002] In order to achieve efficient deceleration and braking, most vehicles nowadays use disc brakes. Disc brakes, also known as disc brakes or disc brakes, mainly consist of a brake disc that rotates on the axle and coaxially with the wheel, brake calipers that span across the brake disc like calipers, and brake pads that press against the brake disc during braking. This causes friction between the brake calipers and the brake disc to produce braking and deceleration.

[0003] However, when there are foreign objects between the brake disc and the brake caliper, the foreign objects may cause unnecessary scratches on the brake disc. When the brake disc needs to be ground to extend its service life, it is necessary not only to remove the center component of the brake disc assembly, but also to confirm whether the flatness of the ground brake disc meets the requirements. It is also necessary to set the brake disc on other fixtures for measurement. After the measurement is completed, the center component and the brake disc need to be assembled before the wheel and brake caliper can be assembled. However, the existing fixtures for grinding and flatness measurement of brake discs are not only inconvenient to operate, but also cannot properly center the brake disc for grinding, and cannot allow the flatness measuring tool to measure the flatness of the fixed diameter of the brake disc.

[0004] In view of this, the inventor, with many years of experience in manufacturing, developing and designing related technical products, has conducted detailed design and evaluation to address the above-mentioned problems. Through the design of positioning modules, fixed sliders and limit modules, the brake disc can be ground and inspected regardless of whether a center component is installed, thereby improving the shortcomings of the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a golf club head and shank machining mold that uses multi-axis machining tools with appropriate fixtures to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention provides a brake disc grinding and testing fixture, which includes a base module, a positioning module, multiple fixed sliders, and a limiting module. The base module includes a drive unit, a control unit, and a turntable unit. The control unit is electrically connected to the drive unit, causing the drive unit to drive the connected turntable unit to actuate. The turntable unit is provided with a central shaft hole and multiple first limiting grooves, wherein the multiple first limiting grooves are formed radially from the central shaft hole along the turntable unit. The positioning module includes a central shaft unit, a cone seat unit, and a clamping unit. One end of the central shaft unit is assembled into the central shaft hole, and the cone seat unit is clamped from the central shaft hole. The other end of the shaft unit is screwed in along the axial direction of the central shaft unit, and the clamping unit is also screwed in along the axial direction of the central shaft unit and abuts against the cone seat unit, wherein the cone seat unit has a conical clamping surface; the plurality of fixed sliders are respectively assembled in the plurality of first limiting grooves and move along the plurality of first limiting grooves, wherein each fixed slider is locked with a locking unit; and the limiting module is provided with at least one connecting through hole, each locking unit passes through the connecting through hole and is locked and limited to a fixed slider, such that the limiting module is located between the turntable unit and the cone seat unit; wherein, when the cone seat unit is screwed in along the central shaft unit, the conical clamping surface of the cone seat unit gradually tapers toward the central shaft hole.

[0007] Furthermore, each of the plurality of first limiting grooves has a limiting opening that is radially opened along the turntable unit.

[0008] Furthermore, the limiting module is a limiting cylinder with an opening on one side and a limiting through hole on the other side, and the connecting through hole is arranged around the limiting through hole. The limiting cylinder allows the limiting through hole to pass through the central shaft unit, and the cone seat unit is screwed into the central shaft unit in the direction of the opening.

[0009] Furthermore, the limiting module has at least two limiting blocks, each of the limiting blocks having a connecting through hole and a connecting slope, wherein each connecting through hole is adjacent to a connecting slope.

[0010] Furthermore, when the cone seat unit is screwed in along the axial direction of the central shaft unit, the cone seat unit causes the conical pressing surface to abut against the connecting slope of each of the limiting blocks.

[0011] Furthermore, the clamping unit includes a nut and a clamping member. When the clamping unit is screwed into the central shaft unit toward the central shaft hole, the clamping member is located between the nut and the cone seat unit.

[0012] Furthermore, a stop ring is formed radially on the outer surface of the central shaft unit where the central shaft hole is located.

[0013] Furthermore, each of the plurality of fixed sliders includes a locking portion and a locking portion protruding from the locking portion. The locking portion is assembled on the first slide rail and the locking portion is accommodated at the second slide rail. Each locking portion is provided with a locking hole, which is used to lock the locking unit.

[0014] Furthermore, the turntable unit is provided with a plurality of second limiting grooves, wherein the plurality of first limiting grooves and the plurality of second limiting grooves are staggered, and wherein the plurality of first limiting grooves are connected to the central shaft hole.

[0015] This utility model discloses a brake disc grinding and testing fixture. The main advantage lies in the assembly structure of the positioning module, the limiting module, and the fixed slider. This allows brake discs with or without an assembly center component to be fixed onto the turntable unit. The control unit then controls the drive unit to actuate the turntable unit, enabling the brake discs to be ground and tested as needed. Specifically, when the brake disc has an assembly center component, it can be first assembled onto the limiting module (which is the limiting cylinder structure), and then the cone seat unit... The center component is pressed against the limiting cylinder, and the center positioning and pressing of the brake disc are completed through the cone seat unit. When the brake disc does not have a structure with a center component, the limiting module, which is a structure of multiple limiting blocks, clamps and presses the brake disc against the turntable unit. The center positioning and pressing of the brake disc against the turntable unit are completed through the cone seat unit. Therefore, the brake disc grinding and testing fixture of this utility model is not only easy to operate and set up, but also saves the time for grinding and testing the brake disc, and increases the accuracy of grinding and testing.

[0060] For information on the technology of this utility model, please refer to [link / reference]. Figures 1 to 8 As shown, this utility model provides a brake disc grinding and testing fixture 100, used to mount a brake disc 200 or a brake disc with a center member 210 for grinding and testing. The brake disc grinding and testing fixture 100 has a base module 10, a positioning module 20, multiple fixed sliders 30, and a limiting module 40, wherein:

[0061] The base module 10 includes a drive unit 11, a control unit 12, and a turntable unit 13. The control unit 12 is electrically connected to the drive unit 11, causing the drive unit 11 to drive the connected turntable unit 13 to actuate. The turntable unit 13 is provided with a central shaft hole 131, a plurality of first limiting grooves 132, and a plurality of second limiting grooves 133. The plurality of first limiting grooves 132 and the plurality of second limiting grooves 133 are formed radially from the central shaft hole 131 along the turntable unit 13, and each of the plurality of first limiting grooves 132 and the plurality of second limiting grooves 133 has a limiting opening 134 radially opened along the turntable unit 13. In addition, each of the plurality of first limiting grooves 132 is provided with a first slide rail 135 and a connected second slide rail 136, and the second slide rail 136 is relative to the first slide rail 135. Each end is provided with a limiting opening 134, and each of the first slide rails 135 has a first radial width D1, and each of the second slide rails 136 has a second radial width D2, such that the second radial width D2 is less than the first radial width D1 but greater than zero. The plurality of first limiting grooves 132 and the plurality of second limiting grooves 133 are staggered. The first slide rails 135 and the second slide rails 136 of the plurality of first limiting grooves 132 are connected to the central shaft hole 131, while the plurality of second limiting grooves 133 are not connected to the central shaft hole 131, but this is not a limitation. Furthermore, the structural design of the plurality of second limiting grooves 133 is roughly the same as that of the first limiting grooves 132. The main difference is that the plurality of second limiting grooves 133 are not connected to the central shaft hole 131, so their structural design will not be described in detail.

[0062] The positioning module 20 includes a central shaft unit 21, a conical seat unit 22, and a clamping unit 23. One end of the central shaft unit 21 is fitted into the central shaft hole 131, and a stop ring 211 is formed radially protruding from the outer surface of the end of the central shaft unit 21 fitted into the central shaft hole 131, and the stop ring 211 abuts against the central shaft hole 131. The conical seat unit 22 is positioned from the other end of the central shaft unit 21 along the central shaft unit. The axial screwing of 21 causes the clamping unit 23 to also screw in along the axial direction of the central shaft unit 21 and abut against the conical seat unit 22. The conical seat unit 22 has a conical clamping surface 221, and the clamping unit 23 includes a nut 231 and a clamping member 232. When the clamping unit 23 is screwed in along the central shaft unit 21 toward the central shaft hole 131, the clamping member 232 is disposed between the nut 231 and the conical seat unit 22.

[0063] The plurality of fixed sliders 30 are respectively assembled in one of the plurality of first limiting grooves 132 or the plurality of second limiting grooves 133, and the plurality of fixed sliders 30 can move along the plurality of first limiting grooves 132 or the plurality of second limiting grooves 133. Each of the plurality of fixed sliders 30 includes a locking part 31 and a locking part 32 protruding from the locking part 31. The locking part 31 is assembled in the first slide rail 135 and the locking part 32 is accommodated in the second slide rail 135. At track 136, each of the locking portions 32 of the plurality of fixed sliders 30 is provided with a locking hole 33, and each locking hole 33 of the fixed slider 30 is used to lock a locking unit 34. Furthermore, the plurality of fixed sliders 30 can be disposed in the plurality of second limiting grooves 133 as needed. When the plurality of fixed sliders 30 are accommodated in the plurality of first limiting grooves 132 or the plurality of second limiting grooves 133, the plurality of fixed sliders 30 generally form a T-shape when viewed radially towards the turntable unit 13, but this is not a limitation.

[0064] The limiting module 40 is provided with at least one connecting through hole 41. Each locking unit 34 passes through one of the connecting through holes 41 and is locked and limited in the locking part 32 of the fixed slider 30, so that the limiting module 40 is disposed between the turntable unit 13 and the cone seat unit 22. When the brake disc 200 is assembled with a center member 210, please refer to [reference needed]. Figure 2 and Figure 5 As shown, the limiting module 40 has a limiting cylinder 42 to support the center component 210 of the brake disc 200. The limiting cylinder 42 has an opening 421 on one side and a limiting through hole 422 on the other side. The connecting through hole 41 is arranged around the periphery of the limiting through hole 422. The limiting cylinder 42 allows the limiting through hole 422 to pass through the central shaft unit 21, and the cone seat unit 22 is screwed into the central shaft unit 21 towards the opening 421 of the limiting cylinder 42. For the brake disc 200 without the center component 210, please refer to [further details]. Figures 6 to 8 As shown, the limiting module 40 is provided with at least two limiting blocks 43. In this embodiment, the limiting module 40 has four limiting blocks 43 to support the brake disc 200. Each limiting block 43 has a connecting through hole 41 and a connecting inclined surface 431. Each connecting through hole 41 is adjacent to a connecting inclined surface 431. When the cone seat unit 22 is screwed in along the axial direction of the central shaft unit 21, the cone seat unit 22 causes the cone-shaped pressing surface 221 to abut against the connecting inclined surface 431 of each limiting block 43.

[0065] When the cone seat unit 22 is screwed into the central shaft unit 21, the cone-shaped clamping surface 221 of the cone seat unit 22 gradually shrinks toward the central shaft hole 131. In this way, when the cone seat unit 22 abuts against the center part 210 of the brake disc 200 or the brake disc 200, the cone-shaped clamping surface 221 moves along the central shaft unit 21 toward the central shaft hole 131 to clamp the center part 210 of the brake disc 200, or further moves the cone-shaped clamping surface 221 along the connecting inclined surface 431 so that the limiting block 43 clamps and limits the brake disc 200 on the turntable unit 13, so as to facilitate subsequent grinding and inspection.

[0066] Please refer to the following: Figures 1 to 8 As shown, the brake disc grinding and testing fixture 100 of this utility model can adjust the configuration of the limiting module 40 according to the structure of the brake disc 200 to be ground and tested. Please refer to [the documentation / reference needed]. Figures 2 to 5As shown, when the brake disc 200 to be ground and inspected is equipped with a center member 210, the limiting module 40 uses the limiting cylinder 42 to assemble the center shaft unit 21 into the center shaft hole 131, and to make the abutment ring 211 abut against the center shaft hole 131. In this embodiment, the center shaft unit 21 is locked into the center shaft hole 131, but this is not a limitation. Then, the limiting through hole of the limiting cylinder 42 is sleeved onto the center shaft unit 21, so that the end of the limiting through hole of the limiting cylinder 42... The locking unit 34 is abutted against the turntable unit 13 and is locked into the locking hole 33 of the locking part 32 of the fixed slider 30 by passing through the connecting through hole 41. At this time, the cone seat unit 22 is screwed into the opening direction of the limiting cylinder 42 along the axial direction of the central shaft unit 21, so that the cone-shaped pressing surface 221 of the cone seat unit 22 presses the central member 210, and the nut 231 of the pressing unit 23 is tightened to limit the fixed slider 30 and reduce slippage. At this time, the cone... The seat unit 22 centers the brake disc 200 on the turntable unit 13, and then the locking unit 34 locks the fixed slider 30. Furthermore, the second radial width D2 of the second slide rail 136 is smaller than the first radial width D1 of the first slide rail 135. Therefore, when the fixed slider 30 is accommodated in the plurality of first limiting grooves 132 or the plurality of second limiting grooves 133, the locking portion 31 of the fixed slider 30 will also be limited to move along the first slide rail 135, and the locking portion... 32 will also be limited to move along the second slide rail 136. In this way, when the brake disc 200 with the center member 210 is mounted on the turntable unit 13 for grinding and testing, when the control unit 12 controls the drive unit 11 to drive the turntable unit 13 to operate, the brake disc 200 with the center member 210 will be tightly limited on the turntable unit 13 by the cone seat unit 22 of the positioning module 20, and will not be displaced by the centrifugal force generated by the rotation of the turntable unit 13, thereby increasing the accuracy of grinding and testing.

[0067] Furthermore, when the brake disc 200 to be ground and inspected is assembled without the center component 210, please refer to [further details needed]. Figures 6 to 8As shown, the limiting module 40 has a locking unit 34 passing through the connecting through hole 41 of the limiting block 43, so that the locking unit is locked in the locking hole 33 of the fixed slider 30. When the nut 231 of the clamping unit 23 and the clamping member 232 assemble the conical clamping surface 221 of the conical seat unit 22 onto the connecting inclined surface 431 of the limiting block 43, the conical clamping surface 221 of the conical seat unit 22 will move along the connecting inclined surface 431 of the limiting block, thereby clamping the brake disc 200 on the outside of the limiting block 43, thereby achieving the goal of clamping the brake disc. The purpose of centering and positioning is that when the brake disc 200 is mounted on the turntable unit 13 for grinding and testing, the control unit 12 controls the drive unit 11 to drive the turntable unit 13 to operate. The brake disc 200 will be tightly confined on the turntable unit 13 by the cone seat unit 22 of the positioning module 20, and will not be displaced by the centrifugal force generated by the rotation of the turntable unit 13. This can increase the accuracy of grinding and testing. Therefore, the brake disc grinding and testing fixture 100 can be suitable for various types of brake discs 200, and thus has the advantages of convenient assembly and easy grinding and testing.

[0068] In summary, the brake disc grinding and testing fixture 100 of this utility model mainly utilizes the assembly structure of the positioning module 20, the limiting module 40, and the fixing slider 30 to fix brake discs 200, whether with or without the assembly center component 210, onto the turntable unit 13. This allows the control unit 12 to control the drive unit 11 to operate the turntable unit 13, thereby enabling the brake disc 200 to be ground and tested as needed. Specifically, when the brake disc 200 has a structure with the center component 210, the brake disc 200 with the center component 210 can be first assembled onto the limiting module 40 of the limiting cylinder 42 structure, and then... The cone seat unit 22 presses the center member 210 against the limiting cylinder 42, thereby achieving center positioning and clamping fixation of the brake disc 200 through the cone seat unit 22. When the brake disc 200 does not have a structure with the center member 210, the limiting module 40 of the limiting block 43 structure clamps and clamps the brake disc 200 against the turntable unit 13, thereby achieving center positioning and clamping fixation of the brake disc 200 against the turntable unit 13 through the cone seat unit 22. Therefore, the brake disc grinding and testing fixture 100 of this utility model is not only easy to operate and set up, but also saves the time for grinding and testing the brake disc 200, and increases its grinding and testing accuracy.
