[0047] See also Figure 1 and Figure 2 The brake caliper includes a connecting bridge 10, a piston housing 11, and an extension arm 12. The piston housing 11 and the extension arm 12 are located on either side of the connecting bridge 10, with the upper ends of the piston housing 11 and the upper ends of the extension arm 12 respectively connected to the connecting bridge 10. A connecting arm 13 is connected to each end of the piston housing 11, and each connecting arm 13 has a connection hole 131 that faces the extension arm 12.

[0048] See also Figures 3 to 7This embodiment provides a brake caliper error-proofing fixture, including a base 20, a support seat 30, a clamping mechanism 40 and a detection device.

[0049] Support base 30 is mounted on base 20 and is used to support the brake caliper's connecting bridge 10. Support base 30 is located between the brake caliper's piston housing 11 and extension arm 12. A clamping mechanism 40 secures the brake caliper to support base 30. A detection device is used to detect the gas flow within airflow channel 31.

[0050] The support base 30 defines an airflow channel 31 with an air inlet and an air outlet. A brake caliper secured to the support base 30 seals the air outlet of the airflow channel 31. A gas delivery device is connected to the air inlet of the airflow channel 31. Specifically, the gas delivery device can be an air pump. A detection device employing existing technology can detect and display the gas flow rate within the airflow channel 31. The gas delivery device and detection device are not shown.

[0051] In this embodiment, the gas delivery device continuously delivers gas to the airflow channel 31, and the detection device displays the gas flow parameters within the airflow channel 31. A worker places the brake caliper on the support base 30 and clamps it using the clamping mechanism 40. When the end face of the clamped brake caliper aligns with the outlet end of the airflow channel 31, forming a seal, the gas flow parameters displayed on the detection device change, indicating that the brake caliper is properly placed and can be further processed, reducing the risk of accidents caused by improperly placed brake calipers.

[0052] In one embodiment, the upper end surface of the support base 30 is used to support the brake caliper, and the upper end surface of the support base 30 is inclined.

[0053] In this embodiment, the worker places the brake caliper on the support block. Since the upper end surface of the support block is inclined, the brake caliper is also placed obliquely, thereby saving space. When the brake blank is processed in this process, the worker can simultaneously Figure 3 More support seats 30 are provided on the equipment to place more brake calipers, thereby improving processing efficiency.

[0054] In one embodiment, the support base 30 includes a vertical support block 32 and a plurality of lateral support blocks 33 .

[0055] The vertical support block 32 is used to vertically support the brake caliper. Its lower end is connected to the base 20. Multiple lateral support blocks 33 are connected to the sides of the vertical support block 32. These lateral support blocks 33 can simultaneously abut against the openings of the corresponding brake caliper piston housings 11.

[0056] The clamping mechanism 40 includes a clamping block 41 and a hydraulic cylinder 42. The clamping block 41 is slidably mounted on the base 20 and can slide toward or away from the vertical support block 32. The clamping block 41 is used to push the brake caliper's extension arm 12. The hydraulic cylinder 42 is mounted within the base 20, with its output connected to the lower end of the clamping block 41. The vertical support block 32 is positioned between the transverse support block 33 and the clamping block 41.

[0057] In this embodiment, the worker places the brake caliper on the vertical support block 32. At this time, the clamping block 41 is located between the extended arm 12 of the brake caliper and the vertical support block 32. The hydraulic cylinder 42 drives the clamping block 41 to slide on the base 20. The clamping block 41 pushes the extended arm 12, thereby moving the entire brake caliper. The mouth of the piston housing 11 on the other side rests on the horizontal support block 33, thereby fixing the brake caliper.

[0058] In one embodiment, the air flow channel 31 includes an annular channel 311 , a connecting channel 312 and a docking channel 313 .

[0059] The annular channel 311 is provided in the vertical support block 32 . The upper end of the connecting channel 312 is communicated with the annular channel 311 . The docking channel 313 is provided on the transverse support block 33 , and the docking channel 313 is communicated with the annular channel 311 .

[0060] Multiple transverse support blocks 33 are arranged along the length of the annular channel 311. Multiple docking channels 313 form the outlet of the airflow channel 31. The lower end of the connecting channel 312 serves as the inlet of the airflow channel 31. An air passage is also defined on the base 20, communicating with the lower end of the connecting channel 312. A gas delivery device delivers air to the airflow channel 31 through the air passage.

[0061] In this embodiment, a worker places the brake caliper on the vertical support block 32. The hydraulic cylinder 42 drives the clamping block 41 to push the extension arm 12, causing the mouth of the brake caliper's piston housing 11 to rest against the transverse support block 33. The mouth of the brake caliper's piston housing 11 is flat, and when it abuts the transverse support block 33, it blocks the opening of the docking channel 313, thereby forming a blockage. Because multiple transverse support blocks 33 are provided, only when the brake caliper is in place can multiple connecting channels 312 be blocked simultaneously, thereby reducing the chance of a collision.

[0062] In one embodiment, two guide posts 34 are connected to the upper ends of the vertical support block 32. The guide posts 34 can be inserted into the connection holes 131 on the brake caliper. The two guide posts 34 are at different heights to fit the tilted brake caliper.

[0063] In this embodiment, a worker places the brake caliper on the vertical support block 32. The hydraulic cylinder 42 then moves the caliper laterally, and the two guide posts 34 cooperate with the hydraulic cylinder 42 to secure the caliper. Furthermore, the ends of the guide posts 34 can be configured as pointed or ball-ends to provide a guiding function. Specifically, the lower end surface of the support base 30, serving as its mounting surface, is parallel to the horizontal plane, and the plane formed by the axes of the two guide posts 34 forms an angle of 15°-40° with the horizontal plane.

[0064] In one embodiment, blocks 35 are connected to both sides of the upper end of the vertical support block 32; the blocks 35 are used to limit the brake caliper. The brake caliper can slide along the axial direction of the guide column 34 between the two blocks 35. The opposite sides of the two blocks 35 include a first limiting surface, a guide slope, and a second limiting surface arranged in sequence. The guide slope is located between the first limiting surface and the second limiting surface. The distance between the second limiting surfaces of the two blocks 35 is smaller than the distance between the first limiting surfaces of the two blocks 35. When the two ends of the brake caliper move on the vertical support block 32, they can slide along the first limiting surface and the guide slope to the second limiting surface. The angle between the plane formed by the axes of the two guide columns 34 and the horizontal plane is set so that it can ensure that the placed brake caliper is tilted during processing, while also ensuring that the worker will not slip due to excessive inclination when placing the caliper.

[0065] In this embodiment, the clamp can realize the function of correcting the placement position of the brake caliper, specifically as follows: when the worker places the brake caliper on the vertical support block 32, the first limit surfaces of the two blocks 35 can cooperate with the vertical support block 32 to realize the initial positioning of the brake caliper, and then the hydraulic cylinder 42 drives the brake caliper to move horizontally, and the brake caliper slides along the first limit ring and the guide slope to the second limit surface to realize the re-positioning of the brake caliper and correct the position of the brake caliper. Then the hydraulic cylinder 42 retreats once and feeds again, and finally the brake is tightened and fixed.

However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
