Description

Technical Field

[0001] This utility model belongs to the field of parts structure inspection technology, specifically relating to a comprehensive inspection tool for brake caliper fixing bracket. Background Technology

[0002] Typically, brake caliper mounts are susceptible to deformation during manufacturing due to riser separation stress, as well as casting defects. The mount, especially the disc groove area, serves as the "installation reference" for the entire braking system. If this reference fails, all components relying on it for positioning (brake pads, brake calipers) will malfunction, potentially leading to: 1. Abnormal brake pad wear and reduced braking efficiency; 2. Brake shudder and steering wheel vibration; 3. Brake pull; 4. Brake noise (abnormal sounds); 5. Brake caliper jamming and complete failure; 6. Structural fracture – the most extreme hazard.

[0003] Existing brake caliper bracket deformation is identified manually by visually inspecting the gap between the bracket and the platform on the machine, or by visually inspecting the hole deviation during machining. For the disc groove functional area, positioning is achieved through the machined threaded hole, and a go / no-go gauge with the same diameter as the brake disc is used to determine whether there is interference with the brake disc. Existing inspection methods require highly skilled personnel, are prone to missing defects visually, and have low inspection efficiency. If severe deformation goes undetected, it can lead to tool breakage during subsequent machining, affecting machining efficiency and other problems. Utility Model Content

Two side beam height inspection blocks are slidably connected to the base plate, and the two side beam height inspection blocks are respectively located on both sides of the disc groove go gauge inspection block.

[0007] In some embodiments, the side beam height detection block has an inverted L-shaped side beam detection wall on the side near the groove gauge detection block, and the side beam detection space is enclosed by the side beam detection wall and the side beam height detection block.

[0008] In some implementations, the upper surface of the groove gauge block has sloping surfaces at both ends along its length, and the sloping surfaces at both ends correspond to the two side beams and are symmetrical.

[0009] In some embodiments, the base plate is also provided with two side beam detection slots, the shape and spacing of which correspond to the two side beams of the brake caliper mounting bracket.

[0010] In some embodiments, the base plate is also provided with a thin beam detection groove and a coarse beam detection groove, the shape and spacing of which correspond to the thin beam and coarse beam of the brake caliper fixing bracket placed in the side beam detection groove state.

[0011] In some embodiments, a thin beam height detection block and a thick beam height detection block are slidably connected on the base plate; when the thin beam height detection block is close to the thin beam detection groove, a thin beam detection space corresponding to the thin beam is formed between the thin beam height detection block and the thin beam detection groove; when the thick beam height detection block is close to the thick beam detection groove, a thick beam detection space corresponding to the thick beam is formed between the thick beam height detection block and the thick beam detection groove.

[0012] In some embodiments, the base plate is provided with a thin beam detection block slide rail and a coarse beam detection block slide rail, the length direction of the thin beam detection block slide rail and the coarse beam detection block slide rail being perpendicular to the length direction of the thin beam and the coarse beam, respectively; the thin beam detection block slide rail is located on the side of the thin beam detection groove away from the coarse beam detection groove, and the coarse beam detection block slide rail is located on the side of the coarse beam detection groove away from the thin beam detection groove; the thin beam height detection block is slidably connected to the thin beam detection block slide rail, and the coarse beam height detection block is slidably connected to the coarse beam detection block slide rail.

[0023] This invention provides a comprehensive inspection tool for brake caliper brackets, addressing the issues of low accuracy and efficiency in existing inspection methods. It enables rapid and accurate identification of bracket deformation and defects in the disc groove functional area. The main objectives of this invention are: 1. To detect brake caliper bracket deformation; 2. To detect casting defects in the disc groove functional area of ​​the brake caliper bracket that interfere with the brake disc or other functional aspects. The basic solution is as follows: The inspection tool is designed based on the structure of the brake caliper bracket (generally a casting). During use, the brake caliper bracket is placed on the tool, and the passage or non-passage of sliding inspection blocks determines whether the bracket is deformed. For the disc groove functional area, a design simulating the brake disc is used, with sliding inspection blocks on both sides. The passage or non-passage of these blocks determines whether the brake caliper bracket has protrusion defects that interfere with the brake disc.

[0024] Please refer to the following first. Figure 5 , Figure 6 The brake caliper mount 100, also known as the brake caliper bracket, is a rigid metal component that is bolted to the vehicle's steering knuckle (front wheel) or axle housing / bracket (rear wheel). Its main function is to provide a precise and stable mounting track for floating brake calipers. The brake caliper mount 100 includes two parallel and oppositely arranged side beams 102. One end of the side beam 102 is connected to the thin beam 103 via an inclined beam along its length, and the other end is connected to the thick beam 104 via an inclined beam. The thin beam 103 and the thick beam 104 are approximately parallel, and a disc groove 101 is formed between them. The disc groove 101 (the functional area of ​​the mount disc groove) is a U-shaped (or C-shaped) opening for accommodating the brake disc. Brake caliper holder 100 is generally manufactured by casting and subsequent machining. Due to casting or other processing, the shape and size of brake caliper holder 100 may be unsatisfactory or changed. Therefore, it is necessary to inspect it to prevent unqualified workpieces from entering the next process or leaving the factory.

[0025] Please see Figures 1 to 6 This utility model discloses a comprehensive inspection tool for a brake caliper fixing bracket, comprising a base plate 1, which serves as the main body of the inspection tool. The base plate 1 preferably has a length and width at least twice the length of the brake caliper fixing bracket, and a thickness at least 20mm. Positioning holes can be provided on the base plate 1 as needed, to allow the entire inspection tool to be mounted and fixed to the workbench using bolts.

[0026] The base plate 1 is provided with a disc groove go gauge check block 2 and a disc groove no-go gauge check block 3 corresponding to the disc groove 101 of the brake caliper bracket 100. A qualified disc groove 101 can just accommodate the disc groove go gauge check block 2, while a qualified disc groove 101 cannot accommodate the disc groove no-go gauge check block 3. Two side beam height check blocks 4 are slidably connected on the base plate 1, and the two side beam height check blocks 4 are located on both sides of the disc groove go gauge check block 2. When the side beam height check blocks 4 are close to the disc groove go gauge check block 2, a side beam detection space corresponding to the side beam 102 of the brake caliper bracket 100 is formed between the side beam height check blocks 4 and the disc groove go gauge check block 2. The side beam detection space can just accommodate the qualified side beam 102.

[0027] More specifically, the groove gauge block 2 is a flat cuboid. The base plate 1 has side beam gauge slide rails 41 at both ends along the length of the groove gauge block 2. The length of the side beam gauge slide rails 41 is parallel to the length of the groove gauge block 2. The side beam height gauge blocks 4 are slidably connected to the side beam gauge slide rails 41. In use, the brake caliper holder 100 to be tested is first placed on the groove gauge block 2. If it fits properly, the side beam height gauge blocks 4 on both sides are moved towards the center to test the side beam 102.

[0028] Furthermore, the side beam height detection block 4 has an inverted L-shaped side beam detection wall 42 on the side near the groove gauge inspection block 2; the horizontal section of the inverted L-shape is located above the vertical section, and the vertical section is located on the side of the groove gauge inspection block 2, while the horizontal section is located above the groove gauge inspection block 2; the side beam detection space is enclosed by the side beam detection wall 42 and the side beam height detection block 4. The enclosed side beam detection space can be closed or open. Taking the illustrated structure as an example, it is not closed. Enclosing the side beam detection space means defining the required spatial range corresponding to the side beam 102. In this scheme, the surfaces of the inverted L-shaped side beam detection wall 42 and the groove gauge inspection block 2 will contact the side beam 102 at least above and on both sides to ensure detection accuracy.

[0029] More preferably, the upper surface of the disc groove gauge inspection block 2 has sloping surfaces 21 at both ends in the length direction, and the sloping surfaces 21 at both ends correspond to the two side beams 102, and the sloping surfaces 21 at both ends are symmetrical. In this solution, the two side beams 102 of the qualified brake caliper fixing bracket 100 can contact the two sloping surfaces 21, thereby allowing for faster leveling and facilitating the subsequent inspection process of the side beam height inspection block 4.

[0030] Furthermore, the base plate 1 is also provided with two side beam detection slots 5, the shape and spacing of which correspond to the two side beams 102 of the brake caliper holder 100. The placement of the brake caliper holder 100 on the side beam detection slots 5 is the reverse of its placement on the disc groove gauge block 2. A qualified brake caliper holder 100 can simultaneously place both side beams 102 correspondingly in the two side beam detection slots 5.

[0031] Furthermore, the base plate 1 is also provided with a thin beam detection groove 6 and a coarse beam detection groove 7. The shape and spacing of the thin beam detection groove 6 and the coarse beam detection groove 7 correspond to the thin beam 103 and the coarse beam 104 of the brake caliper holder 100 when placed in the side beam detection groove 5. When a qualified brake caliper holder 100 places the two side beams 102 in the two side beam detection grooves 5, the thin beam 103 and the coarse beam 104 are precisely located in the thin beam detection groove 6 and the coarse beam detection groove 7 respectively.

[0032] Furthermore, a thin beam height detection block 8 and a thick beam height detection block 9 are slidably connected on the base plate 1. When the thin beam height detection block 8 is close to the thin beam detection groove 6, a thin beam detection space corresponding to the thin beam 103 is formed between the thin beam height detection block 8 and the thin beam detection groove 6; the thin beam detection space can just accommodate a qualified thin beam 103. When the thick beam height detection block 9 is close to the thick beam detection groove 7, a thick beam detection space corresponding to the thick beam 104 is formed between the thick beam height detection block 9 and the thick beam detection groove 7; the thick beam detection space can just accommodate a qualified thick beam 104.

[0033] More specifically, the base plate 1 is provided with a thin beam detection block slide rail 81 and a coarse beam detection block slide rail 91. The length direction of the thin beam detection block slide rail 81 and the coarse beam detection block slide rail 91 is perpendicular to the length direction of the thin beam 103 and the coarse beam 104. The thin beam detection block slide rail 81 is located on the side of the thin beam detection groove 6 away from the coarse beam detection groove 7, and the coarse beam detection block slide rail 91 is located on the side of the coarse beam detection groove 7 away from the thin beam detection groove 6. The thin beam height detection block 8 is slidably connected to the thin beam detection block slide rail 81, and the coarse beam height detection block 9 is slidably connected to the coarse beam detection block slide rail 91.

[0034] The upper part of the thin beam height detection block 8 has a thin beam detection arm 82 extending toward the thin beam detection groove 6. The thin beam detection space is enclosed by the thin beam detection arm 82 and the thin beam detection groove 6. The enclosed thin beam detection space can be closed or open. Taking the illustrated structure as an example, it is close to closed but not completely closed. Enclosing the thin beam detection space means defining the required spatial range corresponding to the thin beam 103. In this solution, the thin beam detection arm 82 can be located above the thin beam detection groove 6. The inner side and bottom surface of the thin beam detection groove 6, as well as the lower surface of the thin beam detection arm 82, jointly detect the shape and size of the cross-sectional profile of the thin beam 103 in four directions. Similarly, the upper part of the thick beam height detection block 9 has a thick beam detection arm 92 extending toward the thick beam detection groove 7. The thick beam detection space is enclosed by the thick beam detection arm 92 and the thick beam detection groove 7.

[0035] In use, the workpiece is placed on the inspection fixture, and the sliding slider is moved. If the slider passes normally, it is considered qualified; if it fails, it is considered a deformed part. The workpiece is placed in the go gauge, and the sliding slider is moved. If the slider passes normally, it is considered qualified; if it fails, it is considered an abnormal part of the groove functional area. The quality personnel are notified to confirm whether the slider fails to pass due to excessive groove material or non-compliant dimensions. The no-go gauge is used to check whether the groove size of the workpiece exceeds the upper limit. If the brake caliper fixing bracket passes the no-go gauge, it is considered unqualified. A preferred embodiment of this utility model involves the following steps: First, the brake caliper holder 100 to be tested is placed on the disc groove go gauge inspection block 2, and the side beam height inspection blocks on both sides are moved inward for testing. Then, the brake caliper holder 100 is removed and placed on the disc groove stop gauge inspection block 3. A gap should form between the top of the disc groove stop gauge inspection block 3 and the side beam 102, preventing it from being completely inserted or passed through. Next, the brake caliper holder 100 is removed, flipped over, and placed on the side beam inspection slot 5, the thin beam inspection slot 6, and the thick beam inspection slot 7. Finally, the thin beam height inspection block 8 and the thick beam height inspection block 9 are moved for testing. This process completes the testing of all key indicators for a brake caliper holder in approximately 20 seconds.

[0036] In summary, the integrated inspection fixture for brake caliper mounting brackets of this invention can detect deformation of the mounting bracket and defects in the functional area of ​​the mounting bracket disc groove. By integrating two solutions onto a single fixture, it effectively improves production efficiency and saves labor costs. Employing go / no-go gauges and sliding inspection blocks (custom-shaped inspection blocks designed according to the shape of the brake caliper mounting bracket) enables rapid and accurate inspection, quickly detecting whether the mounting bracket is deformed and whether there are defects affecting the function of the mounting bracket disc groove. Furthermore, it requires less operator skill, ensuring the accuracy and efficiency of the inspection, and further facilitating full inspection to guarantee the quality of products leaving the factory or entering the next process.

[0037] Finally, it should be noted that the shape / size of each inspection block and inspection slot in this fixture corresponds to / is the same as the workpiece, taking into account the workpiece dimensional tolerances. The above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; obviously, the described embodiments are only some embodiments of this utility model, not all embodiments; for example, the sliding / moving method / direction of each inspection block is not limited to the illustrated embodiments, as long as the required function is achieved; based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model; in the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other; modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some technical features, do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
