[0002] A jig refers to a device used to fix a processing object during the mechanical manufacturing process, so that it occupies a correct position to receive construction or detection, also known as a fixture.
[0003] Generally speaking, any device used to quickly, conveniently and safely install a workpiece in any process of the process can be called a jig. A brake is a device with functions such as decelerating, stopping or maintaining a stopped state of a moving part (or moving machinery), and is a mechanical part that stops or decelerates a moving part in a machine. A bracket usually plays a role of support and limit, and a bracket is usually also provided inside a brake. Such a bracket is a special-shaped part compared with conventional parts. Therefore, it is usually not easy to position and clamp during the processing process, making the processing process of the bracket very inconvenient. Therefore, a structure is set up to solve the problem of inconvenient processing caused by inconvenient positioning and clamping of some brake brackets.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The present utility model will be described in detail below with reference to the drawings and embodiments.
[0021] The positioning fixture for processing the brake bracket is as follows Figure 1 shown, including a support base 1. A bottom limiting part for abutting against the bottom side of the brake bracket is provided on the support base 1. Clamping parts for clamping the brake bracket in the horizontal direction towards each other are provided on both sides of the bottom limiting part. The provided support base 1 is used to achieve stable support and limiting effects on each part, ensuring that the functions of the overall structure can be stably realized. The provided bottom limiting part realizes the support and limiting effects on the brake bracket by abutting against the bottom side of the brake bracket, achieving preliminary limiting of the brake bracket. Under the action of the clamping part, the clamping and limiting effects are applied to the brake bracket, ensuring that the position and state of the brake bracket during processing are more stable, and ensuring that the brake bracket can be stably processed.
[0022] As Figure 1 , Figure 2 and Figure 4 shown, the bottom limiting part includes a fixed support member 2 and several movable support members 3 whose top surfaces all abut against the bottom side of the brake bracket. Through the fixed support member 2 and the movable, the top surface height of the movable support member 3 is adjustable. This setting enables the user to adjust the top height of the movable support member 3 according to the size of the brake bracket, ensuring that the movable support member 3 can stably realize the support and limiting effects on the brake bracket, and ensuring that the brake bracket can be stably processed.
[0023] As Figures 1 - 4 shown, a magnetic block 4 that is fixedly connected to the support base 1 by means of bonding is adhesively bonded to the bottom side of the movable support member 3. By means of the mutual attraction between the magnetic block 4 and the support base 1, the relative position between the movable support member 3 and the support base 1 is ensured to be stable, ensuring that the movable support member 3 can be maintained in a relatively fixed position, enabling the movable support member 3 to stably realize the support and limiting effects on the brake bracket. A limiting bolt 5 that is vertically arranged and whose screw head abuts against the brake bracket is threadedly connected to the movable support member 3. Through the threaded connection between the limiting bolt 5 and the movable support member 3, the limiting bolt 5 can adjust the distance from the top of the limiting screw to the bottom of the magnetic block 4 by rotating relative to the movable support member 3, ensuring that the overall height of the movable support member 3 can be stably adjusted.
[0024] As Figure 1As shown in the figure, the clamping part includes a fixed limit plate 6 and a sliding limit plate 7 which are located on both sides of the brake bracket and have opposite end faces. The end faces of the fixed limit plate 6 and the sliding limit plate 7 are respectively abutted against both sides in the width direction of the brake bracket. The stable limit of the brake bracket is realized through the fixed limit plate 6 and the sliding limit plate 7. A support plate 8 parallel to the sliding limit plate 7 is fixedly connected to the top surface of the support base 1 by welding. A first hexagon socket head adjusting bolt 9 which is rotationally connected to the sliding limit plate 7 is threadedly connected to the support plate 8. By means of the threaded connection between the first hexagon socket head adjusting bolt 9 and the support plate 8, the user can adjust the position of the sliding limit plate 7 through the first hexagon socket head adjusting bolt 9, and realize the adjustment of the clamping or loosening state of the sliding limit plate 7.
[0025] As Figure 1 shown in the figure, symmetrically arranged guide rods 10 which are fixedly connected to the sliding limit plate 7 by welding and are slidably connected to the support plate 8 are provided on the sliding limit plate 7. Guide holes for the guide rods 10 to penetrate and slide are provided on the support plate 8. The stable guiding and limiting effects on the sliding process of the sliding limit plate 7 are realized through the combined action of the guide rods 10 and the guide holes, ensuring that the sliding and limiting functions of the sliding limit plate 7 are more stable.
[0026] As Figure 1 、 Figure 3 and Figure 4 shown in the figure, a horizontally arranged second hexagon socket head adjusting bolt 11 is threadedly connected to the fixed limit plate 6. A limit disc 12 which abuts against the brake bracket is fixedly connected to the second hexagon socket head adjusting bolt 11 on the side far from the screw head by welding. By means of the threaded connection between the second hexagon socket head adjusting bolt 11 and the fixed limit plate 6, the user can adjust the position of the second hexagon socket head adjusting bolt 11 relative to the fixed limit plate 6 by rotating the second hexagon socket head adjusting bolt 11, and further adjust the position of the limit disc 12, so that the limit disc 12 abuts tightly against or loosens the brake bracket, and further realizes the stable clamping and limiting of the brake bracket.
[0027] Working principle: Place the brake bracket between the fixed limiting member and the sliding limiting member, so that the brake bracket abuts against the top surface of the fixed support member 2. Move the movable support member 3 and adjust the top surface height of the movable support member 3, so that the top surface of the limit bolt 5 can abut against the bottom surface of the brake bracket. Drive the sliding limit plate 7 to pre-clamp the brake bracket through the first hexagon socket head adjusting bolt 9, drive the limit disc 12 to pre-clamp the brake bracket through the second hexagon socket head adjusting bolt 11, and fully lock the brake bracket through the first hexagon socket head adjusting bolt 9 and the second hexagon socket head adjusting bolt 11.
[0028] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
