[0001] This utility model relates to the field of brake processing technology, and in particular to an auxiliary device for brake processing. Background Technology

[0002] Brakes typically consist of a brake disc, brake drum, brake pads, and brake fluid. The brake disc is a disc-shaped component that rotates with the axle, and it has a circular mounting hole in the center for easy connection to the axle.

[0003] As an important component of the brake system, the brake disc needs to be professionally polished to restore braking performance after wear and damage to its surface. Therefore, clamping fixtures are required. Currently, commonly used clamping fixtures are usually designed to be relatively fixed, which is not easy to adapt to brake discs of different diameters. This results in poor flexibility when handling brake discs of different sizes, making it difficult to fix them accurately, which brings inconvenience to maintenance work and increases the complexity and time cost of technical operations. Utility Model Content

[0009] As a further embodiment of this utility model, the bottom of the fixed shell is fixedly connected with multiple vertical rods, and the bottom ends of the multiple vertical rods are movably connected with ball bearings, and the ball bearings are in contact with the upper surface of the connecting plate.

[0010] As a further embodiment of this invention, the bracket is located in the middle of multiple clamping blocks.

[0011] As a further improvement of this invention, a rubber pad is fixedly connected to the inclined surface of the clamping block.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0022] Reference Figs. 1-3 An auxiliary device for brake processing includes a base plate 6. Multiple multi-section telescopic rods 7 are fixed to the upper surface of the base plate 6 by bolts. A connecting plate 8 is fixed between the extended ends of the multiple multi-section telescopic rods 7 by bolts. A pushing assembly is provided at the bottom of the base plate 6 to drive the connecting plate 8 to move up and down. The multi-section telescopic rods 7 can guide the connecting plate 8 so that it can move up and down stably.

[0023] A connecting shell 19 is fixed to the upper surface of the connecting plate 8 by bolts. A fixed shell 2 is rotatably connected to the top of the connecting shell 19. Multiple vertical rods are fixed to the bottom of the fixed shell 2 by bolts. The bottom of each vertical rod is rotatably connected to a ball bearing, and the ball bearing contacts the upper surface of the connecting plate 8. Through the cooperation of the vertical rods and the ball bearing, the fixed shell 2 is provided with auxiliary support and moves more smoothly.

[0024] The top of the fixed shell 2 has multiple arc-shaped grooves 12, and in this design, there are four of them. A geared motor 18 is bolted to the inner bottom wall of the fixed shell 2. The geared motor 18 has a self-locking function and can be an NMRV / RV series worm geared motor, which has a good self-locking effect. The principle is as follows: when the lead angle of the worm is less than the equivalent friction angle at the meshing point of the worm gear and worm wheel, the transmission system generates a self-locking effect. At this time, only the worm can drive the worm wheel, and the worm wheel cannot drive the worm in the opposite direction, forming a unidirectional transmission characteristic, thus ensuring that it will not reverse.

[0025] One end of the output shaft of the geared motor 18 is fixed to a rotating shaft 17 by bolts, and the rotating shaft 17 is fixed to the fixed housing 2. The outer circumferential wall of the connecting housing 19 is fixed to a fixing rod 13 by bolts. A sliding sleeve 16 is slidably connected to the outside of the fixing rod 13. A connecting shaft 10 is fixed to the top of the sliding sleeve 16 by bolts. The top of the connecting shaft 10 passes through the arc groove 12 and is fixed to a clamping block 9 by bolts. The connecting shaft 10 contacts the arc groove 12 and slides along the arc groove 12.

[0026] A detachable support assembly is provided at the middle position of the top of the fixed shell 2. The brake disc before grinding is installed on the support assembly. The geared motor 18 rotates clockwise, causing the rotating shaft 17 to drive the fixed shell 2 to rotate. The rotation of the fixed shell 2 causes the arc groove 12 to move with it. Since the position of the connecting shell 19 is fixed, the connecting shaft 10 on the sliding sleeve 16 moves along the arc groove 12. The sliding sleeve 16 is slidably connected to the fixed rod 13. Therefore, during the rotation of the fixed shell 2, under the action of the shape of the arc groove 12, the connecting shaft 10 moves along the arc groove 12. At the same time, the sliding sleeve 16 on the connecting shaft 10 moves along the fixed rod 13, so that the clamping blocks 9 move towards the middle and contact the outer side of the brake disc, so that the brake disc is positioned and clamped, which is convenient for subsequent grinding.

[0027] The support assembly includes a ring frame 1, which is fixed to the top outer wall of the fixed housing 2 by bolts. The top of the ring frame 1 is threaded with a bracket 11. When the bracket 11 needs to be disassembled, the bracket 11 is rotated to separate it from the ring frame 1, making it convenient for the staff to replace the bracket 11. The top of the bracket 11 is shaped like a frustum. The diameter of the bottom of the frustum is larger than the diameter of the circular hole on the convex surface of the brake disc, and the diameter of the top of the frustum is smaller than the diameter of the circular hole on the convex surface of the brake disc.

[0028] In this utility model, it should be noted that the pushing component includes a hydraulic cylinder 4, which is a hydraulic cylinder with a self-locking function. A suitable mechanical self-locking or hydraulic self-locking hydraulic cylinder can be selected according to the actual situation, such as HSG 80 / 60E-1100, locking force 15T-60T series. The hydraulic cylinder 4 is fixed to the upper surface of the base plate 6 by bolts. The extended end of the hydraulic cylinder 4 is equipped with a fixed shaft 3, and the top end of the fixed shaft 3 is fixed to the connecting plate 8. By starting the hydraulic cylinder 4, the multi-section telescopic rod 7 moves synchronously. The extension and retraction of the hydraulic cylinder 4 causes the connecting plate 8 to move downward, thereby adjusting the height of the clamped brake disc, which is convenient for adapting to subsequent grinding devices of different heights.

[0029] The bracket 11 is located in the middle of multiple clamping blocks 9. A rubber pad is glued to the inclined surface of the clamping block 9. A rubber pad with appropriate hardness can be selected according to the actual situation to ensure that it can increase the friction between the clamping block 9 and the brake disc without damaging the brake disc.

[0030] Depending on the actual situation, casters 14 can be selectively fixed to the bottom of the base plate 6 with bolts to facilitate the movement of the device. Casters 14 can be selected to have a self-locking function to prevent them from moving randomly and affecting the work.

[0031] Working principle: When clamping the brake disc, first place the brake disc with the convex side facing up on the bracket 11, so that the truncated cone of the bracket 11 locks into the round hole in the middle of the brake disc, thus supporting the brake disc. Then, power is turned on, and the reduction motor 18 is started. The reduction motor 18 rotates clockwise, causing the rotating shaft 17 to drive the fixed shell 2 to rotate. The rotation of the fixed shell 2 causes the arc groove 12 to move with it. Since the position of the connecting shell 19 is fixed, the connecting shaft 10 on the sliding sleeve 16 moves along the arc groove 12, and the sliding sleeve 16 is slidably connected to the fixed rod 13. Therefore, during the rotation of the fixed shell 2, under the action of the shape of the arc groove 12, the connecting shaft 10 moves along the arc groove 12, and at the same time, the sliding sleeve 16 on the connecting shaft 10 moves along the fixed rod 13, so that the clamping blocks 9 move towards the middle and contact the outer side of the brake disc, so that the brake disc is positioned and clamped, which facilitates subsequent grinding processing.

[0032] It should be noted that the geared motor 18 is existing technology, consisting of a motor part, a reducer part, auxiliary components and an output shaft, etc. It has a self-locking structure. As is common knowledge to those skilled in the art, the minimum speed of the geared motor can reach 0.83 rpm. For example, the speed range of the YE series low-speed motor is 0.83 rpm to 300 rpm. Those skilled in the art can set its speed according to actual needs, which will not be elaborated here.

[0033] This utility model has been described through the above embodiments. Those skilled in the art will understand that this utility model is not limited to the above embodiments. Many more modifications can be made based on the teachings of this utility model, and all such modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
