Technical Field

[0001] The utility model relates to the technical field of automobile brake pad polishing, and particularly relates to a polishing machine for automobile brake pads. Background Technique

[0002] Household cars usually use disc brakes for braking. The components of disc brakes include brake discs, brake pads, brake calipers, and brake cylinders. The brake pads are fixed on the brake calipers. The principle of braking is that the brake calipers clamp the brake discs, and braking force is generated by the friction between the brake pads and the circular metal brake discs.

[0003] In the prior art, the polishing of brake pads is usually carried out in batches using large grinders during production. For repair factories, the number of brake pads polished at one time is not large, and large polishing equipment is not required due to cost reasons.

[0004] Therefore, there is an urgent need for a small polishing equipment that can not only reduce the manufacturing cost, be suitable for polishing small batches of brake pads, but also have a fast polishing process. Content of the Utility Model

[0005] In order to make up for the deficiencies in the prior art and achieve the above functions, the utility model provides a polishing machine for automobile brake pads.

[0006] The utility model is realized by the following technical solutions:

Each polishing mechanism includes a driving wheel a and a driving wheel b that are installed side by side up and down. A driving wheel is connected by a sandpaper belt outside the driving wheel a and the driving wheel b. A spacing plate is arranged at the middle position between the driving wheel a and the driving wheel b. An electric slide table a and an electric slide table b are respectively installed on the upper and lower end faces of the spacing plate. Double-rod cylinders a facing the inner sandpaper belt are installed on both sliders of the electric slide table a. Double-rod cylinders b facing the inner sandpaper belt are installed on both sliders of the electric slide table b. A squeezing wheel that can rotate freely is arranged at the front end of each double-rod cylinder a and double-rod cylinder b.

A slide rail is fixed behind the single-rod cylinder. Two small sliders are arranged on the slide rail, and both small sliders are connected to the upper support mold. The piston rod of the single-rod cylinder faces backward and is connected to the front end of the support mold.

[0009] Furthermore, both the driving pulley a and the driving pulley b are connected to the bearing block b fixed on the front and rear support frames a through transmission shafts; the driving wheels are respectively connected to the front bearing block a through driving shafts and connected to the rear reducer through couplings. Each reducer is connected to the motor, and both the reducer and the motor are fixed on the support plate. The bearing block a is fixed on the support frame b.

[0010] Furthermore, blanking boxes are arranged on the left and right sides of the vertical plate.

[0011] Furthermore, a dust collector is arranged at the middle position of the support plate, and a dust suction frame is arranged at the middle bottom position between the two polishing mechanisms. The dust collector is connected to the dust suction frame through a dust suction pipe.

[0012] Furthermore, both the electric slide table a and the electric slide table b are double-slider electric slide tables, and the sliders of the two can move from the center to both sides to increase the distance between the pressing wheels on the same electric slide table.

[0013] Furthermore, the supporting mold is convex in the middle and concave in the front and rear. The supporting mold can support the brake pads, and the widths of the slide rail, the small slider, and the supporting mold are all smaller than the width of the brake pad.

[0029] like Figures 1 to 4 As shown, the utility model includes two left and right mirror-image polishing mechanisms, each polishing mechanism includes a transmission wheel a101 and a transmission wheel b102 installed in parallel up and down, a driving wheel 1 is connected to the outside of the transmission wheel a101 and the transmission wheel b102 through a sandpaper belt 103, a spacing plate 4 is arranged at the middle position of the transmission wheel a101 and the transmission wheel b102, and an electric slide a401 and an electric slide b402 are respectively installed on the upper and lower end surfaces of the spacing plate 4, and two sliders of the electric slide a401 are both installed with a The double-rod cylinder a403 of the sandpaper belt 103 and the two sliders of the electric slide b402 are both equipped with double-rod cylinders b404 facing the inner sandpaper belt 103, and the front end of each double-rod cylinder a403 and the double-rod cylinder b404 is provided with an extrusion wheel 405 that can rotate freely, which can squeeze the sandpaper belt 103 when the double-rod cylinder a403 and the double-rod cylinder b404 are extended, thereby reducing the distance between the left and right sandpaper belts 103; specifically, the sandpaper belt 103 is a conventional polishing sandpaper combined in front and back into a ring shape, and the outer side is a frosted material.

[0030] A material pushing mechanism is also arranged between the left and right polishing mechanisms, including a single-rod cylinder 5 installed on the vertical plate 501. A slide rail 502 is fixed behind the single-rod cylinder 5. Two small sliders are arranged on the slide rail 502, and both small sliders are connected to the supporting die 503 above. The piston rod of the single-rod cylinder 5 faces backward and is connected to the front end of the supporting die 503. The forward and backward telescoping of the single-rod cylinder 5 can drive the forward and backward movement of the supporting die 503.

[0031] The driving wheel a 101 and the driving wheel b 102 are both connected to the bearing seat b 201 fixed on the front and rear support frame a 202 through a transmission shaft. The driving wheel 1 is connected to the front bearing seat a 2 through a driving shaft respectively, and is connected to the rear reducer 3 through a coupling. Each reducer 3 is connected to the motor 301, and the reducer 3 and the motor 301 are both fixed on the support plate 302. The bearing seat a 2 is fixed on the support frame b 203.

[0032] Feeding boxes 7 are arranged on the left and right sides of the vertical plate 501. A dust collector 602 is arranged at the middle position of the support plate 302. A dust suction frame 6 is arranged at the bottom position between the two polishing mechanisms. The dust collector 602 is connected to the dust suction frame 6 through a dust suction pipe 601. The dust suction frame 6 can absorb the dust generated during polishing.

[0033] The electric slide table a 401 and the electric slide table b 402 are both double-slider electric slide tables. The sliders of the two can move from the center to both sides to increase the distance between the pressing wheels 405 on the same electric slide table.

[0034] The supporting die 503 is convex in the middle and concave in the front and rear. The supporting die 503 can support the brake pad 701. The widths of the slide rail 502, the small slider and the supporting die 503 are all smaller than the width of the brake pad 701 to prevent damage caused by contact with the sandpaper belt 103 with the reduced distance.

[0036] The working principle of the present utility model is as follows: (1) The concave surface of the brake pad 701 is attached above the support mold 503, and the single-rod cylinder 5 pushes backward, enabling the brake pad 701 to enter between the polishing mechanisms on the left and right sides. (2) Manually set the distance between the sliders on the electric slide table a 401 and the electric slide table b 402, so that the left and right pressing wheels 405 are staggered to prevent direct contact. (3) The driving wheel 1 drives the driving wheel 101 and the driving wheel 102 to rotate through the sandpaper belt 103. The double-rod cylinder a 403 and the double-rod cylinder b 404 extend. At this time, the pressing wheel 405 contacts the inner side of the sandpaper belt 103. Since the sandpaper belt 103 is not in a taut state, it can be squeezed, and then the sandpaper belts 103 on both sides approach each other. (4) The outer sides of the sandpaper belts 103 on both sides are in direct contact with the two end faces of the middle brake pad 701 for polishing and frosting. Then, the double-rod cylinder a 403 and the double-rod cylinder b 404 contract, and the sandpaper belts 103 on both sides return to the state as shown in Figure 1 . The single-rod cylinder 5 retracts, and the brake pad 701 is placed in the blanking boxes 7 on both sides.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not restrictive. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solutions of the present utility model.
