Description

Technical Field

[0001] This utility model relates to the field of steel backing production technology, specifically a steel backing positioning fixture. Background Technology

[0002] The steel backing, usually referring to a type of steel plate material, gets its name from its location on the back of the friction material. In automotive braking systems, the steel backing is mainly used to fix the friction material (such as the friction blocks on brake pads) and facilitate the installation of the entire brake pad onto the brake caliper. The steel backing is an important component of the brake pad, and its quality directly affects the braking performance and safety of the vehicle.

[0003] A search revealed a steel-backed positioning fixture (CN205325238U), comprising a base plate, a support frame, two positioning rods, a movable plate, two pressure plates, two support sleeves, and a fixed cylinder. The support frame is fixed to the base plate. The two positioning rods are vertically connected to the support frame. The workpiece to be processed is fitted onto the positioning rods, and the lower part of each positioning rod is connected to the movable plate. One end of each pressure plate presses against the upper end A or B of the workpiece to be processed, and the other end passes through the movable plate. A limit block is connected to the end of each pressure plate passing through the movable plate. Each support sleeve is fitted onto the positioning rod between the workpiece and the support frame. The advantage is that the fixture can clamp the workpiece by simply tightening or loosening the two positioning rods. However, this structure makes it inconvenient to replace the pressure plates during use, which greatly limits its application. Therefore, a new structure is proposed to solve this technical problem.

[0005] To address the shortcomings of existing technologies, this utility model provides a steel-backed positioning clamp, which has the advantages of facilitating the replacement of the pressure plate and solves the problem mentioned in the background art that traditional devices are not convenient for replacing the pressure plate.

[0006] (II) Technical Solution

[0007] To achieve the purpose of facilitating the replacement of the pressure plate mentioned in the background art, this utility model provides the following technical solution: a steel back positioning clamp, including a base, a bracket provided on one side of the outer surface of the base, a threaded seat provided on one side of the outer surface of the base, a threaded rod provided on one side of the outer surface of the threaded seat, a pull rod provided on one side of the outer surface of the threaded seat, a connecting box provided at one end of the pull rod, a device tube provided inside the connecting box, a connecting rod provided inside the device tube, a pressure plate provided at one end of the connecting rod, an auxiliary tube provided on one side of the outer surface of the device tube, an insertion rod provided inside the auxiliary tube, a movable plate provided on one side of the outer surface of the insertion rod, and a spring provided on one side of the outer surface of the movable plate.

[0008] Preferably, there are two brackets, and the two brackets are evenly arranged on one side of the outer surface of the base and are fixedly connected to the base.

[0009] Preferably, there are two threaded seats, and the two threaded seats are evenly arranged on one side of the outer surface of the base, and the outer surface of the threaded seats is fixedly connected to the base.

[0010] Preferably, there are two threaded rods, and the two threaded rods are evenly arranged on one side of the outer surface of the threaded seat on both the left and right sides.

[0011] Preferably, one end of the threaded rod contacts one side of the outer surface of the threaded seat, penetrates one side of the outer surface of the threaded seat, enters the threaded seat, and is threadedly connected to the threaded seat.

[0012] Preferably, there are multiple device tubes, and the multiple device tubes are arranged in pairs in the connecting boxes on the left and right sides. One end of the device tube is fixedly connected to one side of the inner wall of the connecting box, and the other end contacts the other side of the inner wall of the connecting box, and passes through one side of the inner wall of the connecting box to the outer surface of the connecting box, and is fixedly connected to the connecting box.

[0013] The auxiliary tube has upper and lower sliding grooves on the left and right sides of the inner wall. The outer surface of the upper and lower sliding grooves contacts the inner wall of the auxiliary tube and penetrates the inner wall of the auxiliary tube to the outer surface of the auxiliary tube. The insertion rod is set inside the auxiliary tube. One end of the movable plate on the left and right sides is fixedly connected to the outer surface of the insertion rod. The movable plate is slidably connected to the upper and lower sliding grooves, which makes the insertion rod more stable when it moves up and down.

[0014] Furthermore, the spring is installed inside the connecting box, with one end of the spring fixedly connected to one side of the inner wall of the connecting box, and the other end of the spring fixedly connected to one side of the outer surface of the left and right movable plates. This allows the spring to push the movable plates and the insert rod to move when the insert rod is released.

[0015] Furthermore, a device groove is provided on one side of the outer surface of the base, and one side of the outer surface of the device groove contacts one side of the outer surface of the base and extends through one side of the outer surface of the base to the other side of the outer surface of the base. The length of the device groove is the same as the movement length of the pressure plate, so that the lower insertion rod is not subject to movement interference when it moves up and down.

[0016] Compared with the prior art, the present invention provides a steel-backed positioning clamp, which has the following advantages:

[0017] 1. This utility model uses a plug rod installed in the device, which is fixedly connected to the movable plate. The upper and lower ends of the spring are respectively fixedly connected to one side of the outer surface of the movable plate and one side of the inner wall of the connecting box. This allows the plug rod to move up and down under the action of the spring. When the plug rod is disengaged from the connecting rod, the pressure plate can be removed, thereby achieving the effect of replacing the pressure plate.

[0018] 2. In this utility model, a threaded rod is installed inside the device. When the threaded rod is disengaged from the pull rod, the pull rod can move left and right, which in turn causes the pressure plate to move left and right. Therefore, the device can be used for products of different specifications. Attached Figure Description

[0028] Specifically, such as Figures 1-3 As shown, there are two threaded rods 4, and the two threaded rods 4 are evenly arranged on one side of the outer surface of the threaded seat 3 on both the left and right sides.

[0029] Specifically, such as Figures 1-3 As shown, one end of the threaded rod 4 contacts one side of the outer surface of the threaded seat 3, and penetrates one side of the outer surface of the threaded seat 3 into the threaded seat 3, and is threadedly connected to the threaded seat 3.

[0030] Specifically, such as Figures 1-3 As shown, there are multiple device tubes 7, and the multiple device tubes 7 are arranged in pairs, evenly arranged in the connecting boxes 6 on the left and right sides.
