Description

Technical Field

[0001] The utility model relates to the technical field of workpiece positioning equipment, in particular to a brake shoe positioning structure. Background Art

[0002] like Figure 2 As shown, the brake shoe includes an arc panel 8, and an arc support plate 9 fixedly connected to the inner wall of the arc panel 8. The arc support plate 9 is located in the middle of the arc panel 8 and a reinforcing rib is provided between the two. A large hole and a small hole are provided at both ends of the arc support plate 9. In the actual production process, the brake shoe needs to be clamped for processing. For example, the large hole and the small hole can be used to position the two ends of the arc support plate 9 respectively, and then the brake shoe is clamped. Specifically, a positioning rod corresponding to the large hole and the small hole is generally provided on the table, and the large hole and the small hole on the brake shoe are sleeved on the corresponding positioning rod. The diameter of the positioning rod is smaller than the screw rod corresponding to the large hole and the small hole. The brake shoe can be smoothly sleeved on the positioning rod, and the brake shoe can be clamped on the table by a matching nut (specifically, the nut is screwed on the screw rod, and the lower end face is against the arc support plate 9). However, in the actual processing, since both the large hole and the small hole are relatively large, the positioning of the brake shoe may be displaced in the lateral direction, causing the nut to rub against the surface of the arc-shaped support plate 9, resulting in damage to the arc-shaped support plate 9 of the brake shoe. Utility Model Content

[0003] In view of the deficiencies existing in the prior art, the utility model provides a brake shoe positioning structure, which solves the problem in the prior art that clamping may cause accidental damage to the arc-shaped support plate of the brake shoe.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The arc panel is stabilized by the cooperation of the clamping rod and the pressure strip, and the pressure strip provides a limit in the vertical direction, so that the brake shoe can be clamped and is not prone to accidental displacement, thus solving the problem in the prior art that the arc support plate of the brake shoe may be accidentally damaged due to clamping;

[0018] The two brake shoes can also be positioned at the same time, thereby achieving higher working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In the above embodiment, the brake shoe is positioned in the lateral direction by the clamping rod 5 and the pressure strip 6 located on both sides of the arc-shaped panel 8, and the pressure strip 6 cooperates with the center rod 2 to provide vertical positioning for the brake shoe, so that the brake shoe can be clamped more stably and no accidental displacement will occur during the processing, thereby avoiding accidental damage to the brake shoe (including the arc-shaped support plate 9), and solving the problem that the arc-shaped support plate 9 of the brake shoe may be accidentally damaged by clamping in the prior art; specifically, the set pressure ring 3 is similar to the nut in the prior art, but it contacts the pressure strip 6 instead of the arc-shaped support plate 9, and the pressure ring 3 is pressed down so that the pressure strip 6 is pressed tightly on the two arc-shaped support plates 9; this scheme can clamp two brake shoes at the same time, and the efficiency is better, and the corresponding clamping rod 5 and the corresponding mounting seat 4 are four groups, so that the two brake shoes can be better positioned and clamped, and the four groups of mounting seats 4 and the clamping rod 5 can also be arranged to be equidistantly surrounded outside the center rod 2, so that the clamping degree of the two brake shoes can be kept balanced.

[0032] like Figure 1-4 As shown, in a further exemplary embodiment, a top block 10 is further included, and the top block 10 is also fixedly connected to a sliding block 11. Positioning grooves 12 for the sliding block 11 to move are respectively provided at both ends of the pressure strip 6 so that the top block 10 can be located below the top head 7. The sliding block 11 is relatively movable, so that the top block 10 can also move. During the specific clamping, the clamping rod 5 is in a loosened position, and the pressure ring 3 is also in a higher position so that the pressure strip 6 can be lifted, so that the brake shoe can be placed under the top heads 7 at both ends of the pressure strip 6, and the top block 10 can be located under the arc support plate 9 and abut against the arc support plate 9, and then the pressure strip 6 is lowered so that the top head 7 is pressed on the arc support plate 9, and the arc panel 8 is pushed so that its inner wall abuts against the arc surface of the top head 7, and then the clamping rod 5 is adjusted to abut against the outer wall of the arc panel 8, and the pressure ring 3 is adjusted to abut against the pressure strip 6, so that the clamping of the brake shoe is completed; the positioning groove 12 is for the convenience of adjusting the position of the top block 10 when the pressure ring 3 is not tightened. Specifically, the positioning groove 12 is extended along the length direction of the pressure strip 6.
