Description

Technical Field

[0001] This utility model relates to the field of brake pad steel backing processing technology, specifically a brake pad steel backing shot blasting equipment. Background Technology

[0002] Brake pads are an important safety component in a car's braking system, used to decelerate the vehicle. The brake pad backing is a thin steel plate located inside the brake pad and connected to the friction material. Brake pad shot blasting equipment is a mechanical device that treats the surface of brake pads. Through a shot blaster, high-speed shot is propelled onto the surface of the brake pad, thereby removing stains and strengthening and cleaning the surface of the brake pad, effectively improving the adhesion of the brake pad.

[0003] Traditional brake pad steel back shot blasting equipment suffers from inconsistent results when shot of different sizes impacts the brake pad steel back surface with varying forces, leading to uneven processing and affecting the uniformity of the shot blasting process. Therefore, we have proposed a new brake pad steel back shot blasting equipment to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a shot blasting equipment for brake pad steel backing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a brake pad steel back shot blasting equipment, comprising an outer cover, an inner cover installed inside the outer cover, rotating seats movably arranged at both ends inside the inner cover, a third servo motor installed on one side of the rotating seats, a grinding wheel installed inside the rotating seats, and blades installed on the outer side wall of the grinding wheel, a first servo motor installed at the front end of the outer cover, and a conveying pipe installed at the front end of the first servo motor, a feed hopper installed at the top end of the conveying pipe, fixing blocks fixed at both ends inside the feed hopper, and spring guide columns fixed at the top ends of the fixing blocks, and a screening screen frame installed at the top end of the spring guide columns, a cam movably arranged at the bottom end of the screening screen frame, a rotating shaft installed inside the cam, and a second servo motor installed on one side of the rotating shaft.

[0006] Preferably, a plurality of blades are provided, and the plurality of blades are installed at equal intervals on the outer side wall of the grinding wheel.

[0007] Preferably, four sets of spring guide columns are provided, and the four sets of spring guide columns are symmetrically distributed about the central axis of the feed hopper.

[0008] Preferably, the cams are provided in two sets, and the two sets of cams are symmetrically distributed on the outer wall of the rotating shaft about the central axis of the screening frame.

[0009] Preferably, the cross-section of the screening frame is smaller than the cross-section of the feed hopper, and the screening frame, with the assistance of the spring guide column, forms an up-and-down sliding structure inside the feed hopper.

[0010] Preferably, a conveying auger is movably installed inside the conveying pipe, and a first servo motor is installed at the front end of the conveying auger.

[0011] Preferably, the inner cover has rolling grooves at both the front and rear ends, and rolling balls are movably disposed inside the rolling grooves.

[0012] Preferably, there are several balls, which are distributed in a ring at equal intervals inside the rolling groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the brake pad steel back shot blasting equipment not only achieves the filtration of sand shot, but also enables the sand shot to enter the equipment interior evenly, avoiding blockage, and enables the grinding wheel to drive the blades to rotate smoothly for shot blasting.

[0014] (1) The feed hopper is used to introduce sand shot into the inside of the equipment to process the brake pad steel back. By setting up components such as a second servo motor, a screening frame, a spring guide column and a cam, after the sand shot is poured into the inside of the feed hopper, the screening frame in the above components can filter the sand shot, preventing sand shot with a mesh size larger than the screening frame from entering the inside of the equipment and hitting the surface of the brake pad steel back, thus affecting the uniform processing effect of the brake pad steel back.

[0015] (2) When the shot material enters the shot blasting equipment, it enters the inside of the conveying pipe through the feed hopper and then enters the inside of the inner cover for shot blasting. When a conveying auger is installed inside the conveying pipe, the conveying auger rotates inside the conveying pipe through the first servo motor, so that the shot material entering the inside of the conveying pipe through the feed hopper is evenly conveyed to the inside of the inner cover by the conveying auger, and it is not easy to cause blockage.

[0016] (3) By setting up a ball and rolling groove assembly, the rotating seat rotates and drives the dividing grinding wheel to rotate, causing the blades to rotate and project the sand shot material onto the workpiece surface at a certain speed and angle. By setting the above-mentioned assembly at both ends inside the inner cover, the sliding friction between the rotating seat and the inner cover is transformed into rolling friction, thereby enabling the dividing grinding wheel to drive the blades to rotate smoothly and project the sand shot material.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides an embodiment: a brake pad steel back shot blasting equipment, including an outer cover 1, an inner cover 2 installed inside the outer cover 1, rotating seats 18 movably arranged at both ends inside the inner cover 2, and a third servo motor 7 installed on one side of the rotating seats 18, a dividing grinding wheel 15 installed inside the rotating seats 18, and blades 14 installed on the outer side wall of the dividing grinding wheel 15, a first servo motor 4 installed at the front end of the outer cover 1, and a conveying pipe 3 installed at the front end of the first servo motor 4, a feed hopper 5 installed at the top end of the conveying pipe 3, fixing blocks 13 fixed at both ends inside the feed hopper 5, and spring guide columns 10 fixed at the top ends of the fixing blocks 13, and a screening screen frame 9 installed at the top end of the spring guide columns 10, and a cam 12 movably arranged at the bottom end of the screening screen frame 9. The feed hopper 5 has a rotating shaft 11 installed inside, with a second servo motor 6 mounted on one side of the rotating shaft 11. Several blades 14 are evenly spaced on the outer wall of the grinding wheel 15, uniformly projecting the abrasive material. Four sets of spring guide columns 10 are symmetrically distributed about the central axis of the feed hopper 5. Two sets of cams 12 are symmetrically distributed about the central axis of the screening frame 9 on the outer wall of the rotating shaft 11. The cross-section of the screening frame 9 is smaller than that of the feed hopper 5. With the assistance of the spring guide columns 10, the screening frame 9 forms a sliding structure inside the feed hopper 5. The symmetrically distributed spring guide columns 10 and cams 12 drive the screening frame 9 to move stably up and down, screening the abrasive material.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the second servo motor 6 is started to drive the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the cam 12 to rotate. The rotation of the cam 12 pushes the screening screen frame 9 to move up and down inside the feed hopper 5 through the elastic extension force of the spring guide column 10, so as to screen the sand and shot material poured into the screening screen frame 9.

[0025] The conveying pipe 3 is equipped with a conveying auger 8, and a first servo motor 4 is installed at the front end of the conveying auger 8.

[0026] Specifically, such as Figure 2 As shown, the first servo motor 4 starts and drives the conveying auger 8 to rotate inside the conveying pipe 3. The rotating conveying auger 8 then evenly conveys the shot material into the inner cover 2 for shot blasting.

[0027] The inner cover 2 has rolling grooves 17 at both the front and rear ends. Rolling balls 16 are movably arranged inside the rolling grooves 17. There are several rolling balls 16, which are distributed in a ring at equal intervals inside the rolling grooves 17. The evenly distributed rolling balls 16 make the rotating seat 18 rotate more smoothly inside the inner cover 2.

[0028] Specifically, such as Figure 4 As shown, when the third servo motor 7 drives the rotating seat 18 to rotate inside the inner cover 2, the ball bearings 16 that are attached to the surface of the rotating seat 18 also rotate, which converts the sliding friction between the ball bearings 16 and the rotating seat 18 into rolling friction, thereby making the rotating seat 18 rotate more smoothly, and making the grinding wheel 15 drive the blade 14 to rotate smoothly.

[0029] Working principle: When this utility model is in use, the first servo motor 4 is started to drive the conveying auger 8 to rotate inside the conveying pipe 3. Then, the sand shot material is taken and put into the screening frame 9 inside the feed hopper 5. Then, the second servo motor 6 is started to drive the rotating shaft 11 to rotate. The rotating shaft 11 drives the cam 12 to rotate. The rotation of the cam 12 pushes the screening frame 9 to move up and down inside the feed hopper 5 through the elastic extension force of the spring guide column 10, screening the sand shot material poured into the screening frame 9. The sand shot material that is smaller than the mesh of the screening frame 9 after screening is then put into the inner cover 2 through the rotating conveying auger 8. The third servo motor 7 is started to drive the rotating seat 18 to rotate inside the inner cover 2. The rotation of the rotating seat 18 drives the blade 14 to rotate through the grinding wheel 15, throwing out the sand shot material that has entered the inner cover 2. The sand shot material is thrown at a certain speed and angle through the bottom of the inner cover 2 onto the surface of the brake pad steel back for corresponding processing.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
