Description

Technical Field

[0001] The utility model relates to the technical field of brake pad steel back processing devices, in particular to a brake pad steel back drilling device. Background Art

[0002] At present, during the processing of semi-metallic brake pads for automobile brakes, several assembly holes for positioning or fixing friction materials need to be opened on the side of the brake pads to facilitate the fixed installation of the brake pads. The traditional processing method requires the operator to place the steel back on the front end of the drilling machine. After the placement is completed, the drilling machine is used to drill holes. However, since the operator needs to place the steel back directly on the front end of the drilling machine, there are certain safety hazards.

[0003] A brake pad steel back drilling device recorded in a Chinese utility model patent (publication number CN217192723U) sets the loading station and the drilling station at different positions, so that the loading position is far away from the drilling position, which can ensure that the workers are away from the drill bit of the drilling mechanism during the placement of the steel back, ensuring safety and eliminating safety hazards.

[0004] However, due to the large number of car models, there are many varieties and specifications of brake pads that match them. The steel back shape of each brake pad is different, and the position and angle of the processing hole are different. This device requires a long time to debug each time before changing the variety, which reduces processing efficiency and increases labor costs. Utility Model Content

[0005] In view of the above problems, a brake pad steel back drilling device is provided, which solves the problem that the device is inconvenient to quickly drill holes on the steel backs of different brake pads through an arc-shaped adjustment mechanism.

[0006] In order to solve the problems of the prior art, the utility model provides a brake pad steel back drilling device, which is used for drilling holes in the steel back. It has a frame and a rotating disc rotatably arranged above the frame, and also includes a feeding mechanism arranged on the frame and a plurality of drilling jigs for fixing the steel back arranged along the circumferential direction of the rotating disc.

[0007] Preferably, the drilling jig comprises a fixing seat, on which is provided an arc-shaped adjustment mechanism for positioning the steel back and a fixing mechanism for fixing the steel back.

[0008] Preferably, the arc adjustment mechanism includes a slide groove, which is arranged at the bottom of the fixed seat. A rotating shaft is slidably provided within the range of the slide groove, an elastic plate is rotatably provided between the two rotating shafts, and a ejector for adjusting the curvature of the elastic plate is threaded on the fixed seat.

[0009] Preferably, the fixing mechanism comprises a telescopic rod, the telescopic rod is arranged at the upper end of the fixing seat, and a pressing plate is provided at the output end of the telescopic rod.

[0010] Preferably, the feeding mechanism comprises a storage box for storing the steel backs to be drilled, and a discharge port facing the rotating disc is provided on the lower end side of the storage box.

[0011] Preferably, the feeding mechanism further comprises a pushing device for pushing the steel back located at the bottom in the placement box out of the discharge port.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model drives the threaded rod to rotate in the fixed seat by rotating the turning handle. The rotation of the threaded rod will cause the top block at its end to move toward or away from the elastic plate. When the turning handle is turned, the threaded rod rotates, causing the top block to move toward the elastic plate, thereby pressing the elastic plate and changing its curvature to adapt to steel backs with different curvatures, thereby improving the convenience of the device.

[0014] 2. The utility model sets a placement box and then starts the cylinder, so that the push plate enters the insertion port, and pushes the steel back located at the bottom of the placement bin out of the discharge port, so that it can be smoothly moved to the fixed seat on the rotating disc 302 for subsequent drilling operations, ensuring that the staff is away from the drill bit of the drilling mechanism during the placement of the steel back, ensuring safety, eliminating safety hazards, and improving work efficiency.
