Description

Technical Field

[0001] This utility model relates to the field of caliper testing technology, specifically to an intelligent caliper testing device. Background Technology

[0002] The brake caliper is the core component of a disc brake system. It uses hydraulically driven internal pistons to push brake pads to clamp the brake disc, generating frictional resistance to slow the vehicle. Typically made of metal, it comes in fixed and floating designs, characterized by rapid heat dissipation and sensitive response. It directly affects braking performance and driving safety, and therefore requires intelligent high-pressure airtightness testing equipment for sealing performance testing.

[0003] Caliper seal performance testing primarily detects leaks through pressure changes. Its core principle involves two methods: The positive pressure method involves injecting gas or liquid into the tested sealing cavity (such as the caliper piston chamber) and pressurizing it. Sensors monitor pressure decay or flow rate changes to determine the seal's tightness. The negative pressure method involves creating a vacuum in the sealing cavity to form a negative pressure environment, observing the pressure recovery rate or the escape of bubbles during water immersion to locate the leak point. The testing system collects pressure data in real time, combines it with algorithms to analyze whether the leakage exceeds a threshold, and ultimately evaluates the seal's performance compliance.

[0004] Traditional high-pressure airtightness testing equipment does not have an automatic connection function. Before carrying out the testing work, the user still needs to manually fix the clamps and then manually connect the airtight tubes, which leads to a high labor intensity for the staff and affects the overall efficiency of the testing work. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent caliper testing device to solve the problem that in the prior art, manually fixing the caliper and then manually connecting the airtight tube affects the overall efficiency of the testing work.

[0007] An automated mechanism is located on the top of the base and is used to automatically fix and connect the brake calipers.

[0008] A heat fade test mechanism is installed on the top of the base and is used to simulate a high-temperature environment to test the brake caliper.

[0009] The automated mechanism includes an automatic connection component and an automatic fixing component. The automatic connection component includes a lifting cylinder and a fitting chamber. The lifting cylinder is fixedly installed on the top of the base. A connecting arm is fixedly installed on the telescopic end of the lifting cylinder.

A side support arm is fixedly installed on the outer wall of the connecting arm. A column is slidably connected to the inner wall of the side support arm. The column is fixedly installed on the top of the base. The fitting chamber is fixedly installed on the top of the base.

[0010] As a preferred embodiment of the above technical solution, the automatic fixing component includes a stand, which is fixedly installed on the top of the machine base. The number of stands is set to two, and the two stands are symmetrically arranged about the fitting chamber. A clamping cylinder is fixedly installed on the side of the stand, and the telescopic end of the clamping cylinder extends to the other side of the stand and is fixedly connected to a clamping block.

[0011] As a preferred embodiment of the above technical solution, a follower rod is fixedly installed on the outer wall of the clamping block, and the outer wall of the follower rod is slidably connected to the inner wall of the stand.

[0012] As a preferred embodiment of the above technical solution, the thermal attenuation test mechanism includes a base plate, which is fixedly mounted on the top of the base.

[0014] As a preferred embodiment of the above technical solution, a movable cover is fixedly installed at the end of the connecting kit, and an electric heating component is fixedly installed on the inner wall of the movable cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, through the overall design of an automated mechanism, allows the user to insert the caliper into the inner cavity of the fitting chamber. Then, by controlling the extension of the clamping cylinder, the clamping block is pressed against the outer wall of the caliper, automatically clamping and fixing the caliper. Next, the lifting cylinder retracts, causing the connecting arm to move downwards, sealing the insertion pipe into the piston opening of the caliper. This allows the caliper cavity to connect automatically to the high-pressure airtightness testing device via an airtightness testing pipe, enhancing the automation level of the structure, reducing the labor intensity of workers, and ultimately improving the overall efficiency of the testing work.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a caliper intelligent testing device, including a base 1, a high-pressure airtightness testing device 11 fixedly installed on the top of the base 1, a warning light 12 fixedly installed on the top of the high-pressure airtightness testing device 11, and further including:

[0025] Automation mechanism 2 is located on the top of the base 1 and is used to automatically fix and connect the brake caliper.

[0026] The heat fade test mechanism 3 is set on the top of the base 1. The heat fade test mechanism 3 is used to simulate a high temperature environment to test the brake caliper.

[0027] The automated mechanism 2 includes an automatic connection component and an automatic fixing component. The automatic connection component includes a lifting cylinder 21 and a fitting chamber 27. The lifting cylinder 21 is fixedly installed on the top of the base 1. A connecting arm 22 is fixedly installed on the telescopic end of the lifting cylinder 21. A connector 23 is fixedly installed on the inner wall of the connecting arm 22. The top of the connector 23 is threadedly connected to an airtightness testing pipe 24. The end of the airtightness testing pipe 24 away from the connector 23 is threadedly connected to the testing end of the high-pressure airtightness testing device 11. A side support arm 25 is fixedly installed on the outer wall of the connecting arm 22. A column 26 is slidably connected to the inner wall of the side support arm 25. The column 26 is fixedly installed on the top of the base 1. The fitting chamber 27 is fixedly installed on the top of the base 1. The shape of the inner cavity of the fitting chamber 27 matches the shape of the caliper. After the caliper is inserted into the inner cavity of the fitting chamber 27 and clamped and fixed, the lifting cylinder 21 can be controlled to retract, driving the connecting arm 22 to move downward, thus causing the connector 23 to move downward. 23 is sealed and inserted into the piston opening of the caliper. At this time, the caliper cavity can be connected to the high-pressure airtightness testing device 11 through the airtightness testing pipe 24 to realize the automatic connection function, reducing the labor intensity of workers. During the process of the lifting cylinder 21 driving the connecting arm 22 to lift and lower, the side support arm 25 will slide synchronously on the outer wall of the column 26, thereby increasing the stability of the insertion pipe 23. After the caliper is connected, the high-pressure airtightness testing device 11 is controlled to work, and gas is delivered into the caliper. The pressure decay change is monitored by the sensor to judge the seal. If it is unqualified, the warning light 12 is controlled to work to sound an alarm. It is worth noting that the high-pressure airtightness testing device 11 in this solution is a device that can be purchased on the market by those skilled in the art. The device has not been structurally modified in this paper. Therefore, those skilled in the art are familiar with its working principle based on professional knowledge and can use it skillfully. Therefore, this paper will not elaborate on it.

[0028] As one implementation method in this embodiment, such as Figure 3 As shown, the automatic fixing assembly includes a stand 28, which is fixedly installed on the top of the base 1. There are two stands 28, which are symmetrically arranged about the fitting chamber 27. A clamping cylinder 281 is fixedly installed on the side of the stand 28. The telescopic end of the clamping cylinder 281 extends to the other side of the stand 28 and is fixedly connected to a clamping block 282. When the caliper is inserted into the inner cavity of the fitting chamber 27, the clamping cylinder 281 is extended, which can drive the clamping block 282 to press against the outer wall of the caliper, thereby realizing the function of automatically clamping and fixing the caliper and improving the overall efficiency of the inspection work.

[0029] As one implementation method in this embodiment, such as Figure 3As shown, a follower rod 283 is fixedly installed on the outer wall of the clamping block 282. The outer wall of the follower rod 283 is slidably connected to the inner wall of the stand 28. When the clamping cylinder 281 drives the clamping block 282 to move, the follower rod 283 will slide on the inner wall of the stand 28, increasing the stability of the movement of the clamping block 282.

[0030] As one implementation method in this embodiment, such as Figure 4 , Figure 5 As shown, the thermal attenuation test mechanism 3 includes a base plate 31, which is fixedly installed on the top of the base 1. A groove 32 is provided on the top of the base plate 31, and a sliding seat 33 is slidably connected to the inner wall of the groove 32. Through the design of the base plate 31, the groove 32 and the sliding seat 33, it is convenient for the user to adjust the movable cover 38 to slide left and right, which facilitates the use or removal of the movable cover 38.

[0031] As one implementation method in this embodiment, such as Figure 4 , Figure 5 As shown, a support frame 34 is fixedly installed on the top of the sliding seat 33. A damping shaft 35 is rotatably connected to the inner wall of the support frame 34. The end of the damping shaft 35 extends to the outer side of the support frame 34 and is fixedly connected to a handle 36. A connecting kit 37 is fixedly sleeved on the outer wall of the damping shaft 35. Through the design of the support frame 34, the damping shaft 35, the handle 36 and the connecting kit 37, it is convenient for the user to adjust the rotation of the movable cover 38, making it convenient for the use or removal of the movable cover 38.

[0032] As one implementation method in this embodiment, such as Figure 4 , Figure 5 As shown, a movable cover 38 is fixedly installed at the end of the connecting kit 37. An electric heating element 39 is fixedly installed on the inner wall of the movable cover 38. If the caliper under test needs to be tested in a simulated high-temperature environment, the movable cover 38 is adjusted to the top of the fitting chamber 27 and placed over the caliper. The electric heating element 39 is then controlled to work for a period of time to simulate heating of the caliper. After heating is completed, the movable cover 38 is removed, and then an airtightness test is performed. The maximum operating temperature of the electric heating element 39 is above 300°C. This is because in daily working conditions, the brake disc temperature is usually between 100°C and 200°C in urban driving scenarios, and can be increased to 150°C to 250°C when driving on highways. The temperature setting for high-temperature environments needs to cover the actual operating temperature range under different working conditions.

[0033] Working principle: In use, the caliper is inserted into the inner cavity of the fitting chamber 27. The clamping cylinder 281 extends, causing the clamping block 282 to press against the outer wall of the caliper, automatically clamping and fixing the caliper. Then, the lifting cylinder 21 retracts, causing the connecting arm 22 to move downwards, sealing the insertion port 23 into the piston opening of the caliper. At this time, the caliper cavity can be connected to the high-pressure airtightness testing device 11 through the airtightness testing pipe 24, achieving automatic connection. Then, the high-pressure... When the airtightness testing device 11 is in operation, gas is supplied to the inside of the caliper. The pressure decay change is monitored by the sensor to determine the seal. If the seal fails, the warning light 12 is activated to sound an alarm. If the caliper under test needs to be tested in a simulated high-temperature environment, after the caliper is fixed with the clamping block 282, the movable cover 38 is adjusted to the top of the fitting chamber 27 and placed over the caliper. The electric heating component 39 is controlled to work for a period of time to simulate heating of the caliper. After heating is completed, the movable cover 38 is removed, and the airtightness test can then be performed.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
