Description

Technical Field

[0001] This utility model relates to the field of brake pad painting technology, and in particular to a paint spraying fixture for automotive brake pads. Background Technology

[0002] Brake pads are mainly composed of a steel backing and a friction layer. A brake pad painting fixture is a tool used to clamp and fix brake pads during the painting process, and it is widely used in the field of fixtures.

[0003] A brake pad painting fixture (publication number: CN 213222888 U) is disclosed on the patent website. It effectively prevents the friction material layer of brake pads from being sprayed with paint, improving practicality. The fixture includes a fixed plate, a placement plate, an adjusting threaded rod, a threaded tube, a slider, and a clamping plate. The placement plate is fixedly installed at the center of the front end of the fixed plate. A placement groove is formed at the center of the front end of the placement plate, the width of which corresponds to the width of the brake pad. An installation groove is formed at the left end of the placement plate. The threaded tube is fixedly installed in the installation groove, and the adjusting threaded rod is installed in the threaded tube. The right end of the adjusting threaded rod is screwed into the right side of the installation groove from the left end of the threaded tube. The slider is installed in the installation groove, and the slider and installation groove are tightly slidably connected. The right end of the adjusting threaded rod is rotatably connected to the left end of the slider. A sliding hole is formed at the front end of the installation groove, and a connecting rod is provided at the front end of the slider. The connecting rod extends from the rear end of the sliding hole and is tightly slidably connected to the sliding hole. The clamping plate is fixedly installed at the front end of the connecting rod.

[0004] The aforementioned technology prevents the brake pads from being painted on by placing them inside the mounting plate, thus avoiding any impact on their performance. However, it uses a threaded rod to move the clamping plate and hold the brake pads in place. If the clamping is too tight, it can damage the brake pads, while if the clamping force is too loose, it can cause the brake pads to fall off, thus affecting the clamping effect. Therefore, there is room for improvement. Utility Model Content

[0005] This invention provides a paint spraying fixture for automotive brake pads to solve the problems mentioned in the background art.

[0006] To address the aforementioned problems, this utility model provides a paint spraying fixture for automotive brake pads. The brake pads to be painted are formed by hot pressing a steel backing and a friction material layer. The surface of the friction material layer has symmetrical chip removal grooves. The paint spraying fixture consists of a placement plate and a clamping plate. The placement plate has a placement cavity for inserting the friction material layer of the brake pad, and the steel backing of the brake pad covers the placement plate. A contact plate is fixed in the center of the placement cavity, which abuts against the surface of the friction material layer. Two sets of guide rods are symmetrically fixed on both sides of the contact plate in the placement cavity. There are two clamping plates, which are slidably disposed on both sides of the contact plate via the guide rods. The thickness of the clamping plate is less than the width of the chip removal grooves. A positioning ring is fixed at the outer end of the guide rod, and a spring is sleeved in the guide rod, with the spring located between the clamping plate and the positioning ring.

[0007] Preferably, the contact plate has a vacuum suction cup connected to a vacuum pump in the middle.

[0008] Preferably, the end of the guide rod near the surface of the contact plate is a threaded end, and a limit ring is threadedly connected to the threaded end of the guide rod.

[0009] Preferably, the placement plate is provided with two symmetrical limiting grooves on both sides of the matching steel back.

[0010] The beneficial effects of adopting the above technical solutions are:

[0011] 1. By embedding the friction material layer into the placement cavity of the placement plate, it can be protected, thereby preventing paint from being sprayed onto the surface of the friction material layer and avoiding affecting the subsequent use effect.

[0012] 2. The clamping plate is embedded in the chip removal groove, and the spring allows the clamping plate to move in the guide rod. The two clamping plates can clamp the chip removal groove, so that the brake pad is firmly placed in the placement plate.

[0013] 3. By using a vacuum pump in conjunction with a vacuum suction cup, the friction material layer can be adsorbed, further improving the stability of the brake pads clamped in the placement plate.

[0014] 4. By using the limiting grooves on both sides of the placement plate to stabilize the steel back, the stability of the brake pads clamped in the placement plate can be further improved. Attached Figure Description

[0022] like Figure 1-3 In this embodiment, a paint spraying fixture for automotive brake pads is provided. The brake pad 1 to be painted is formed by hot pressing a steel backing 11 and a friction material layer 12. The surface of the friction material layer 12 is provided with symmetrical chip removal grooves 13. The paint spraying fixture 2 is composed of a placement plate 21 and a clamping plate 22. The placement plate 21 is provided with a placement cavity 211 for inserting the friction material layer 12 of the brake pad 1. A contact plate is fixed in the center of the placement cavity 211 to abut against the surface of the friction material layer 12. Plate 212, the placement cavity 211 contains two sets of guide rods 213 symmetrically fixed on both sides of the contact plate 212, the clamping plate 22 consists of two pieces, which are slidably disposed on both sides of the contact plate 212 via the guide rods 213 respectively, the thickness of the clamping plate 22 is less than the width of the chip discharge groove 13, the outer end of the guide rod 213 is fixed with a positioning ring 214, and a spring 215 is sleeved in the guide rod 213, and the spring 215 is located between the clamping plate 22 and the positioning ring 214.

[0023] With the above technical solution, when in use, the friction material layer 12 of the brake pad 1 is inserted into the placement cavity 211 of the placement plate 21 in the paint spraying fixture 2. The steel back 11 covers and abuts against the placement plate 2. Before the friction material layer 12 is inserted into the placement cavity 211, a clamping plate 22 is inserted into a chip removal groove 13 in the friction material layer 12. Since the thickness of the clamping plate 22 is less than the width of the chip removal groove 13, the clamping plate 22 can move in the guide rod 213, which facilitates the insertion of another clamping plate 22 into another chip removal groove 13. Then, under the rebound of the spring 215, the two clamping plates 22 move in the guide rod 213, so that the clamping plates 22 clamp the chip removal groove 13. At the same time, the brake pad 1 moves to the center position in the placement cavity 211, so that the brake pad 1 is stably clamped in the placement plate 21, improving the stability during spraying. The placement cavity 211 can protect the friction material layer 12 from paint spraying onto the surface of the friction material layer 12 during spraying, so as to avoid affecting subsequent use.

[0024] Preferably, the contact plate 212 is provided with a vacuum suction cup 216 connected to a vacuum pump in the middle.

[0025] Through the above technical solution, the vacuum suction cup 216 can adsorb the middle part of the friction material layer 12, further improving the stability of the brake pad 1 clamped in the placement plate 2.

[0026] Preferably, the end of the guide rod 213 near the surface of the contact plate 212 is provided as a threaded end 217, and a limit ring 218 is threadedly connected to the threaded end 217 of the guide rod 213.

[0027] Through the above technical solution, the limiting ring 218 and the threaded end 217 can be used to adjust the position of the limiting ring in the guide rod 213 of the 218, thereby adjusting the position of the clamping plate 22 in the guide rod 213, so that the clamping plate 22 can be inserted into the chip discharge groove 13, and also facilitates the insertion and clamping of the brake pad 1 in the chip discharge groove 13 at different positions.

[0028] Preferably, the placement plate 2 is provided with two matching steel backing 11 limiting grooves 219 on both sides.

[0029] Through the above technical solution, the setting of the limiting groove 219 can further enhance the limiting of the steel back 11 by the placement plate 2, thereby improving the stability of the brake pad 1 in the placement plate 2.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
