Description

Technical Field

[0001] The present invention relates to the technical field of automotive brake pads, and particularly to a central positioning device for automotive brake pads. Background Art

[0002] Automotive brake pads refer to the friction materials fixed on the brake drums or brake discs that rotate with the wheels, and achieve the purpose of vehicle deceleration through frictional action.

[0003] Automotive brake pads are composed of steel plates, adhesive heat insulation layers, and friction materials. In order to improve the matching degree between new brake pads and brake discs and enhance the initial friction performance of the brake pads, a layer of coating needs to be added to the friction materials of some automotive brake pads. This layer is usually added at the central position of the friction materials. During the processing, the brake pads need to be aligned with the central position of the rubber roller to ensure the coating position. When processing brake pads of different sizes, manual adjustment is required to align the brake pads with the central position, resulting in low efficiency and easy occurrence of defective products, which is not conducive to the normal progress of production. Therefore, we propose a central positioning device for automotive brake pads. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention discloses a central positioning device for brake pads to solve the problem that when processing brake pads of different sizes, manual adjustment is required to align the central position of the brake pads, and debugging is needed during the adjustment process, which is not conducive to the normal progress of production as mentioned in the above background art. Technical Solution

The front positioning rack and the rear positioning rack are engaged with the transmission gears. The front positioning rack and the rear positioning rack are arranged in the card slots of the device box body, and the front section of the product positioning rack is in contact with the brake pads; Rack positioning device: The rack positioning device includes a spring and a positioning pin, and the spring and the positioning pin are fixed inside the device box body.

[0006] Preferably, the lower surface of the bracket is connected to a base, the upper surface of the bracket is provided with a device box body, and a gear transmission assembly and a limit baffle are provided inside the device box body.

[0007] Preferably, the gear transmission components mesh with each other, and one handle component is fixed on the gear transmission components.

[0008] Preferably, the front positioning rack and the rear positioning rack mesh with the gear transmission components, and the front positioning rack and the rear positioning rack are arranged in the grooves of the device box body. After the ends of the front positioning rack and the rear positioning rack contact the limit baffle in the device box body, they cannot move further.

[0009] Preferably, the spring and the positioning pin are fixed in the device box body. The spring and the positioning pin are in contact with each other. After the positioning pin becomes loose, it can contact the rear positioning rack.

[0010] The present invention discloses a central positioning device for automobile brake pads, and the beneficial effects thereof are as follows: For this central positioning device for automobile brake pads, when central positioning of the brake pads is required, first loosen the positioning rack to be greater than the length of the brake pads. After the ends of the front positioning rack and the rear positioning rack contact the limit baffle in the device box body, they cannot move further. Place the brake pads between the two positioning racks, and rotate the handle component. The constant transmission ratio of the gears causes the positioning racks to contract equidistantly. Under the action of the positioning racks, adjustment is performed so that brake pads of different sizes can be located at the central position of the positioning device.

[0011] For this central positioning device for automobile brake pads, when the central positioning of the brake pads is completed and the same model of products are still produced subsequently, loosen the positioning pin through the rack positioning device. The positioning pin contacts the rear positioning rack to fix the positions of the two racks. At the same time, the spring contacts the positioning pin to fix the position of the positioning pin. Placing the same model of brake pads between the two positioning racks completes the central positioning of the products. BRIEF DESCRIPTION OF THE DRAWINGS

Embodiment

[0013] An embodiment of the present invention discloses a central positioning device for an automobile.

[0014] As shown in the attached Figures 1-4 figure, it includes a bracket, a gear transmission assembly, a product positioning rack, a rack positioning device 4. Brake pads 5 are placed between the product positioning racks. A device box body 102 is provided on the upper surface of the base 101. A limit baffle 104 and a transmission gear 201 are provided on the device box body 102. A handle assembly 202 is provided on the transmission gear 201. A front positioning rack 301 and a rear positioning rack 302 are arranged in the device box body card slot. The front positioning rack 301 and the rear positioning rack 302 are engaged with the transmission gear; When the center positioning of the brake pads 5 is required, first fix the tooling at the center position to be positioned, rotate the handle assembly 202 to drive the rotation of 5 transmission gears 201. The transmission gears 201 are engaged through gears. Using the constant transmission ratio between the gears, the front end spacing of the front positioning rack 301 and the rear positioning rack 302 is equally enlarged, and the claw distance at the front section of the front positioning rack 301 and the rear positioning rack 302 is made larger than the length of the brake pads 5. When the ends of the front positioning rack 301 and the rear positioning rack 302 contact the limit baffle 104, the front positioning rack 301 and the rear positioning rack 302 cannot move further; Place the brake pads 5 between the front positioning rack 301 and the rear positioning rack 302. By rotating the handle assembly 202, drive the rotation of 5 transmission gears 201. The transmission gears 201 are engaged through gears. Using the constant transmission ratio between the gears, the transmission gears 201 drive the front end spacing of the front positioning rack 301 and the rear positioning rack 302 to move and contract equally until the positioning gear contacts the brake pads 5, and the lower belt moves to take away the brake pads 5; At this time, the center positioning of this type of brake pads is completed. If other models need to be replaced for production subsequently, repeat the above operations; As shown in the attached Figures 2-4 figure, a spring (401) and a positioning pin (402) are arranged in the card slot of the device box body 102. The spring (401) is arranged inside the card slot, and the positioning pin (402) is connected to the spring (401); If the same model of product is still to be produced, move the positioning pin 402 out of the card slot inside the device box body 102. The elastic force of the spring 401 moves the positioning pin 402 towards the rear positioning rack 302. The contact between the positioning pin 402 and the rear positioning rack 302 locks the position of the rear positioning rack 302. The position locking state of the rear positioning rack 302 is transmitted to the front positioning rack 301 through the transmission gear 201. The positions of the front positioning rack 301 and the rear positioning rack 302 are locked simultaneously, and the front positioning rack 301 and the rear positioning rack 302 cannot move. Place the same model of product between the front positioning rack 301 and the rear positioning rack 302 to complete the positioning of this type of brake pads.

[0015] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
