Description

Technical Field

[0001] This utility model belongs to the technical field of piston clamp body machining fixtures, and in particular relates to a single piston clamp body boring and limiting fixture. Background Technology

[0002] The braking system is the core device for safe vehicle operation. It converts kinetic energy into heat energy through friction to achieve deceleration or stopping. Its key components include the brake disc (or drum), brake pads, hydraulic lines, and piston caliper. As the core actuator of disc brakes, the piston caliper is usually made of high-strength aluminum alloy and integrates a hydraulic piston and brake pad fixing mechanism. When the driver presses the brake pedal, the hydraulic system pushes the piston inside the caliper to move outward, causing the brake pads on both sides to clamp the rotating brake disc, generating braking force through friction.

[0003] After the clamp body is cast, it still needs to be bored, cut, and ground on a lathe to finally be processed into a clamp body that can be used directly. The boring process mainly involves creating a space on the clamp body for piston installation and movement. It needs to be fixed on a machine tool and then processed by a boring tool.

[0004] There is a single-piston clamp structure. Because it needs to adapt to the requirements of brake and vehicle components, it needs to be limited in the horizontal front-back and left-right directions after being placed on the fixture. The current method is to set conventional fixture jaws at the front and back positions. Due to the limited limiting area in the left and right directions and the proximity of the jaws in the front-back direction, the only way to limit is to use screws screwed in from the side. Although it can limit, the operation is not convenient and the reliability is not good. Since symmetrical limiting is required, manual screwing can easily cause the caliper to shift, ultimately resulting in scrap.

[0005] To address the aforementioned issues, this application proposes a single-piston clamp boring and limiting fixture. Utility Model Content

[0006] The purpose of this invention is to provide a single-piston clamp boring and limiting fixture, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a single-piston clamp boring and limiting fixture, comprising a fixedly connected mounting base and a limiting platform. The front end of the limiting platform is provided with several limiting rods that match the corresponding contour height of the clamp body. The front end of the mounting base is equipped with two sets of grippers for front and rear limiting of the clamp body with the limiting platform as the axis of symmetry. Both sides of the limiting platform are fixed with upright plates for vertical movement of the side limiting blocks. The upright plates are connected with rotating rods that drive the two side limiting blocks to move upward. Under normal conditions, the side limiting blocks are driven downward by springs and form left and right limits at the upper ends of both sides of the clamp body.

[0009] Furthermore, the upright plate has an "L" shaped structure, with the long side being horizontal and fixed to the upper side of the limiting platform by bolts and mounting holes, and the short side being vertical. The side limiting block slides in the movable groove of the short side through a rectangular block fixed at one end, and the spring abuts between the movable groove and the rectangular block.

[0010] Furthermore, a through hole is provided at the upper end of the movable groove, and a screw hole coaxial with the through hole is provided in the rectangular block. The long screw passes through the through hole and is screwed to the screw hole. The long screw also passes through the middle of the spring.

[0011] Furthermore, the end faces of the side limiting blocks that are close to each other match the side profile of the clamp body, and the side limiting blocks slide vertically along the end faces of the two upright plates that are close to each other.

[0012] Furthermore, the rotating rod consists of two rods respectively hinged to the outside of the two upright plates, and a U-shaped plate is fixed to one end of each of the two rotating rods. A drive column that fits in the U-shaped plate is fixed to the end of the rectangular block away from the side limiting block.

[0013] Furthermore, the other ends of the two rotating rods are integrally fixed by a connecting rod.

[0014] Furthermore, the front end of the limiting platform is connected to a central limiting block that is inserted into the clamp body.

[0015] This utility model has the following beneficial effects:

[0016] This utility model replaces the traditional side bolt limiting structure by setting a side limiting block that can move up and down. When the side limiting block moves up, it can play a role in avoiding the clamp body when it is put in. When it moves down, it can achieve left and right limiting in the horizontal direction. Since the side limiting block cannot move left and right, automatic and reliable limiting can be achieved by spring alone, ensuring the reliability and consistency of the clamp body's limiting.

[0017] This utility model uses a rotating rod and a U-shaped plate to link the side limiting blocks at both ends. When the clamp body needs to be placed in, simply press the connecting rod to move the side limiting blocks at both ends to avoid it. After the clamp body is placed in, release the connecting rod, and it will automatically limit the position under the action of the spring, thus combining reliable limiting and convenient operation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figures 1-5 As shown, this utility model is a single-piston clamp boring and limiting fixture, including a fixedly connected mounting base 1 and a limiting platform 2. The front end of the limiting platform 2 is provided with several limiting rods 21 that correspond to the contour height of the clamp body 9. A central limiting block 22, which is inserted into the clamp body 9, is connected to the front end of the limiting platform 2. The central limiting block 22 is fixed to the limiting platform 2 by bolts. The front end of the central limiting block 22 has a chamfer to facilitate docking with the clamp body 9. After the central limiting block 22 is inserted into the clamp body 9, it has already controlled the vertical and horizontal movement of the clamp body 9. Pre-limiting: At this point, the clamp body 9 is pushed towards one side of the limiting platform 2, and several limiting rods 21 simultaneously hold the clamp body 9 against it. Two sets of grippers 3 are mounted on the front end of the mounting base 1 with the limiting platform 2 as the axis of symmetry for front and rear limiting of the clamp body 9. The grippers 3 are fitted with two long screws, clamping plates, and nuts. The screws are screwed to the mounting base 1 and fixed with nuts. The clamping plates slide axially and rotate circumferentially along one of the screws. The rotation is used to avoid obstruction when the clamp body 9 is inserted, and the axial sliding with the nut at the upper end of the screw achieves the clamping or loosening of the clamp body 9. Specifically, as shown... Figures 1-2 loosen and Figures 3-4 As shown in the diagram, press firmly.

[0030] Furthermore, both sides of the limiting platform 2 are fixed with upright plates 4 for the vertical movement of the side limiting block 5. The upright plates 4 have an "L" shape structure, with the long side being horizontal and the short side being vertical. The side limiting block 5 slides in the movable groove 42 on the short side through a rectangular block 51 fixed at one end. The movable groove 42 is through-hole. The spring 8 abuts between the movable groove 42 and the rectangular block 51. The movable groove 42 forms a space for receiving the movable groove 42 after compression.

[0031] Furthermore, the long side of the upright plate 4 is provided with at least two mounting holes 41. After the upright plate 4 passes through the mounting holes 41 with bolts, it is fixed by pressing it against the limiting platform 2. The two upright plates 4 are symmetrically arranged on the upper ends of both sides of the limiting platform 2.

[0032] Furthermore, the upright plate 4 is connected to a rotating rod 6 that drives the two side limiting blocks 5 to move upward. Under normal conditions, the side limiting blocks 5 are driven downward by the spring 8 and form left and right limits on the upper ends of both sides of the clamp body 9. The downward limit is automatically achieved by the spring 8, and the upward movement is achieved by manually pressing the connecting rod 62, thereby achieving a stable cooperation between the side limiting blocks 5 in limiting and disengaging.

[0033] Furthermore, a through hole 43 is provided at the upper end of the movable groove 42, and a screw hole 511 coaxial with the through hole 43 is provided in the rectangular block 51. The long screw 7 passes through the through hole 43 and is screwed and fixed to the screw hole 511. The long screw 7 also passes through the middle of the spring 8. The sliding fit between the long screw 7 and the through hole 43 guides the sliding of the drive column 52 in the movable groove 42, and at the same time provides reliable support for the spring 8.

[0034] Furthermore, the end faces of the side limiting blocks 5 that are close to each other match the side profile of the clamp body 9, and the side limiting blocks 5 slide vertically along the end faces of the two upright plates 4 that are close to each other. The sliding of the side limiting blocks 5 and the upright plates 4 ensures the supporting position of the side limiting blocks 5 on the clamp body 9.

[0035] Furthermore, there are two rotating rods 6, each hinged to the outside of the two upright plates 4. One end of each rotating rod 6 is fixed with a U-shaped plate 61. The end of the rectangular block 51 away from the side limiting block 5 is fixed with a drive column 52 that fits in the U-shaped plate 61. The other ends of the two rotating rods 6 are fixed together by a connecting rod 62. The cooperation between the drive column 52 and the U-shaped plate 61 is used for the linkage of a single side limiting block 5 and a single rotating rod 6. The connecting rod 62 at the other end of the rotating rod 6 links the two rotating rods 6 together. When the connecting rod 62 is operated, it can drive the two side limiting blocks 5 to move upward synchronously, making the operation more convenient.

[0036] It is understood that this utility model uses vertically movable side limiting blocks to replace the traditional bolt structure, and achieves automatic limiting through springs. Then, the two limiting blocks are linked together by the cooperation of the rotating rod, the U-shaped plate and the drive column. Pressing the connecting rod can simultaneously lift the two limiting blocks to form a clearance space for the clamp body to be inserted. After releasing, the springs automatically reset to complete the horizontal left and right limiting. This application simplifies the operation process through mechanical linkage while ensuring the consistency of clamp body limiting, and has the dual advantages of limiting accuracy and operation convenience.

[0037] A specific application of this embodiment is as follows: the limiting platform 2 is fixed to the mounting base 1 by bolts, the limiting rod 21 is installed on the limiting platform 2 by threads, the central limiting block 22 is fixed to the limiting platform 2 by bolts, the grippers 3 are symmetrically installed on the mounting base 1 in two sets, the side limiting block 5 slides in the vertical direction on the inner side of the upright plate 4, and the side limiting block 5 is automatically in the limiting state under the action of the spring 8;

[0038] Press down on the connecting rod 62, and under the action of the rotating rod 6, drive the U-shaped plate 61 to reverse. The U-shaped plate 61 drives the driving column 52 and drives the rectangular block 51 to slide in the movable groove 42. Finally, the side limiting block 5 slides upward to avoid interference with the insertion of the clamp body 9. Place the clamp body 9 at the front end of the limiting platform 2, insert the center limiting block 22 into the clamp body 9, and several limiting rods 21 hold it against the rear end contour of the clamp body 9. After releasing the connecting rod 62, the side limiting block 5 moves down under the action of the spring 8. The symmetrically arranged side limiting blocks 5 limit the clamp body 9 at the left and right ends in the horizontal direction. Rotate the pressure plate on the gripper 3 to the front end of the clamp body 9, and tighten the nut on the gripper 3. With the cooperation of the nut and the screw, push the pressure plate to press the clamp body 9 from the front.
