Description

Technical Field

[0001] The invention relates to the technical field of automobile component bench testing, and more specifically to a brake caliper durability testing device. Background Art

[0002] The brake caliper durability test equipment is a device used to simulate and test the durability and reliability of the brake caliper in the automobile braking system. In coastal areas, high humidity areas or places frequently eroded by salt water, such as ice on the road in winter, the ground needs to be melted by spreading salt. When the vehicle is driving on these roads, the water containing salt will enter the surface and inside of the brake caliper during the driving process of the vehicle, thereby causing corrosion to the brake caliper. Therefore, by conducting a salt spray test on the brake caliper, the corrosion situation in the real environment is simulated to ensure the corrosion resistance of the brake caliper.

[0003] In the prior art, the corrosion resistance of brake calipers is mainly tested by salt spray test. The brake caliper sample is placed in a salt spray chamber so that it is exposed to a fog environment containing sodium chloride to simulate the salt spray corrosion in the natural environment. The corrosion resistance of the brake caliper is judged by ensuring the temperature and humidity in the salt spray chamber and observing the rust, peeling and discoloration on the surface and inside of the brake caliper. However, when the brake caliper is subjected to salt spray test in the existing salt spray chamber, it is only necessary to place the brake caliper in the salt spray chamber, and then pass the fog containing sodium chloride into the salt spray chamber through an atomizing tube. Since the position of the atomizing tube is fixed, when the fog enters the salt spray chamber, the fog circulates in the salt spray chamber, and the side of the brake caliper close to the atomizing tube is more severely corroded by the salt spray, while the inside of the brake caliper and the side away from the atomizing tube are relatively slightly corroded by the salt spray, resulting in different degrees of corrosion of various parts of the brake caliper, and the brake caliper is not uniformly corroded by the salt spray, which leads to errors in the corrosion resistance results of the brake caliper.

[0004] In view of the above situation, the present invention designs a brake caliper durability test equipment to solve the above technical problems. Summary of the invention

[0016] 1. A brake caliper durability test device provided by the present invention drives a motor to rotate so that a control block moves synchronously, and drives control components on both sides of a support plate to perform periodic multi-angle rotation through the control block. The periodic multi-angle rotation of the control component can drive the brake caliper to rotate at multiple angles, and can expose the inside of the brake caliper to more salt mist, thereby ensuring that the surface of the brake caliper can be corroded by the salt mist. When the control component drives the brake caliper to rotate at multiple angles, the control block can make the flow control component move back and forth, thereby realizing convection of the salt mist in the atomization chamber, and the control component and the flow control component can realize that when the inner side of the brake caliper is parallel to the flow control component, the flow control component can make the salt mist flow to the inside of the brake caliper, thereby ensuring that the inside of the brake caliper can also be evenly corroded by the salt mist, thereby avoiding different degrees of salt mist corrosion on the surface and inside of the brake caliper, resulting in errors in the corrosion resistance test results of the brake caliper.

[0017] 2. The present invention provides a brake caliper durability test equipment. The equipment drives the control block through the setting of the control component, so that the control component can rotate periodically at multiple angles, so that all surfaces and the interior of the brake caliper can be evenly corroded by the salt spray, and at the same time, the salt spray can be prevented from corroding the same position of the brake caliper surface for a long time during the flow process, and the different degrees of salt spray corrosion on different parts of the brake caliper can be avoided, thereby ensuring the accuracy of the brake caliper salt spray test results.

[0018] 3. The present invention provides a brake caliper durability test equipment, which cooperates with the flow control part through a control component. The control component drives the brake caliper to rotate at multiple angles. When the inner surface of the brake caliper is parallel to the flow control part, the control block drives the flow control part to reciprocate. The reciprocating motion of the flow control part can push the salt mist in the atomization chamber to move to the inside of the brake caliper, so that the inside of the rotating caliper can be corroded by the salt mist, thereby ensuring that the surface and interior of the brake caliper are corroded to the same degree, thereby avoiding uneven corrosion of the surface and interior of the brake caliper by the salt mist, resulting in errors in the corrosion resistance test results of the brake caliper.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0030] refer to Figure 1 , Figure 2 , Figure 3A brake caliper durability test equipment is used for the corrosion resistance experiment of the brake caliper, comprising an equipment body 1, a control box 11 is arranged on one side of the equipment body 1, and a sealing cover 12 is rotatably installed on the top of the equipment body 1, a storage cavity 13 for placing experimental materials is opened at the bottom of the equipment body 1, the storage cavity 13 is symmetrically arranged on both sides of the equipment body 1, and a motor placement cavity 15 is arranged between the storage cavity 13, an atomization cavity 16 for conducting experiments is opened above the storage cavity 13, an atomization adjustment mechanism 14 is arranged in the atomization cavity 16, and the atomization adjustment mechanism 14 is used to adjust the size of the salt spray flow rate, the drive motor 2 is arranged in the motor placement cavity 15, and the output end of the drive motor 2 runs through the motor placement cavity 15, the drive The output end of the driving motor 2 is coaxially connected to a control block 4, support plates 3 are symmetrically arranged on both sides of the control block 4, and a control component 5 is arranged in the middle of the support plates 3 on both sides, the control block 4 is connected to the control component 5 away from the output end of the driving motor 2, and flow control parts 6 are arranged on both sides of the control component 5. The rotation of the driving motor 2 drives the control block 4 to rotate, and the control component 5 is driven to move by the rotation of the control block 4, so that the brake caliper installed on the control component 5 can be evenly sprayed with salt mist, the control block 4 rotates itself to make the flow control part 6 move up and down, and the flow control part 6 reciprocates up and down to make the salt mist convection in the atomization chamber 16, and the control component 5 drives the brake caliper to rotate in a circle to cooperate with the salt mist convection, thereby changing the flow direction of the salt mist so that the salt mist flows to the inside of the brake caliper.

[0031] During the working process, the operator first prepares the required sodium chloride solution, then adds the sodium chloride solution into the storage chamber 13, adjusts the atomization adjustment mechanism 14 according to the size of the brake caliper, so that the size of the salt spray flow rate can be adjusted according to the size of the brake, and then the staff places the brake caliper on the control component 5. After the brake caliper is installed, the sealing cover 12 is rotated so that the sealing cover 12 seals the atomization chamber 16 to prevent the salt spray from flowing out through the gap between the sealing cover 12 and the equipment body 1, and the humidity and temperature inside the atomization chamber 16 are ensured by the control box 11, and then the drive motor 2 is started, and the drive motor 2 rotates to drive the control block 4 to rotate, and the control block 4 rotates to drive the control component 5 between the support plates 3 on both sides to rotate, and the control block 4 The control component 5 is driven to perform periodic multi-angle rotation, so that the brake caliper at one end of the control component 5 can rotate at multiple angles, and more surfaces of the brake caliper can be exposed to the salt spray. When the control component 5 drives the brake caliper to rotate, the control block 4 can drive the flow control member 6 to reciprocate up and down, and the flow control member 6 can make the salt spray in the atomization chamber 16 convect, so as to push the salt spray in the atomization chamber 16 into the brake caliper, so that each corner of the brake caliper can be filled with salt spray, so as to prevent the salt spray from entering the brake caliper, resulting in the brake caliper not being corroded by the salt spray, and ensuring that each part of the brake caliper can be evenly corroded by the salt spray, so as to avoid different degrees of surface and internal corrosion of the brake caliper, thereby causing errors in the results of the rotating caliper salt spray test.

[0032] The control block 4 includes a rotating block 41 and a swinging plate 42, wherein the rotating block 41 is coaxially mounted with the swinging plate 42, and the swinging plate 42 is connected to the output end of the driving motor 2, and the rotating block 41 is connected above the swinging plate 42, and the rotating block 41 is tiltedly arranged on the swinging plate 42, and the end of the rotating block 41 away from the swinging plate 42 is connected to the control component 5. Through such an arrangement, when the driving motor 2 drives the swinging plate 42 to rotate, the rotating block 41 cooperates with the control component 5 to enable the control component 5 to perform periodic multi-angle rotation, and when the control component 5 rotates at multiple angles, the swinging plate 42 can drive the flow control component 6 to reciprocate, so that the salt mist in the atomization chamber 16 can be pushed to flow toward the control component 5 through the flow control component 6 and the control component 5.

[0033] The rotating block 41 and the swing plate 42 are arranged alternately, and the swing plate 42 is on one side of the rotating block 41. When the driving motor 2 rotates, the swing plate 42 first contacts the flow control member 6, and the two sides of the swing plate 42 are arc-shaped, the brake caliper is semi-circular and the brake caliper is provided with a groove for installing the brake disc. In the initial state, the groove on the brake caliper is in a vertical state with the flow control member 6 (the state of the surface in the figure is the state that the groove on the brake caliper faces the flow control member 6). When the driving motor 2 rotates, the driving motor 2 drives the swing plate 42 and the rotating block 41 to rotate. At this time, since the rotating block 41 and the swinging plate 42 are staggered, when they rotate, the swinging plate 42 first contacts the flow control member 6, and the swinging plate 42 drives the flow control member 6 to reciprocate. At this time, the flow control member 6 can push the salt mist in the atomization chamber 16 to flow toward the brake caliper. When the groove on the brake caliper faces the flow control member 6, the salt mist can directly enter the groove opened on the brake caliper, so that at the same time, it can be ensured that the groove on the brake caliper is filled with more salt mist, thereby preventing the flowing salt mist from flowing along the surface of the brake caliper and failing to flow into the groove opened on the brake caliper.

[0034] refer to Figure 1 , Figure 2 , Figure 3 As shown, the atomization adjustment mechanism 14 includes an atomization tube 141, an adjustment sleeve 142, a conical block 143 and a screw 144. The atomization tube 141 is arranged to pass through the storage chamber 13, and two groups of atomization tubes 141 are arranged. An adjustment sleeve is coaxially arranged on the atomization tube 141, and the top of the adjustment sleeve 142 is a conical structure. A conical block 143 is arranged below the adjustment sleeve 142, and the adjustment sleeve 142 is fixed to the atomization tube 141 by a screw 144.

[0035] During the working process, the operator first loosens the screw 144 that fixes the adjusting sleeve 142. At this time, the operator can move the adjusting sleeve 142 up and down, and can adjust the size of the salt mist passing through the atomizing tube 141 by adjusting the conical block 143 set below the sleeve 142. After adjusting the salt mist flow rate according to the size of the brake caliper, tighten the screw 144 to fix the adjusting sleeve 142 on the atomizing tube 141 through the screw 144. After the experiment, the adjusting sleeve 142 can be moved downward by loosening the screw 144, and the atomizing tube 141 is sealed by the conical block 143. At the same time, the conical structure at the top of the adjusting sleeve 142 can prevent salt mist from accumulating on the top of the adjusting sleeve 142, thereby preventing the adjusting sleeve 142 from being eroded by salt mist for a long time, resulting in a reduction in the service life of the adjusting sleeve 142.

[0036] The control assembly 5 includes a connecting column 51, a limiting rod 52, a fixing rod 53, a connecting rod 54 and a clamping piece 55. One end of the connecting column 51 is connected to the rotating block 41, and the other end of the connecting column 51 is connected to the clamping piece 55. Support plates 3 are symmetrically arranged on both sides of the connecting column 51, and the supporting plates 3 are rotatably connected to the connecting rods 54. Fixing rods 53 are arranged on both sides of the connecting column 51, and the limiting rods 52 are respectively connected to both ends of the fixing rod 53. The fixing rod 53 is parallel to the supporting plate 3, and the fixing rod 53 and the limiting rod 52 are rotatably arranged.

[0037] During operation, when the rotating block 41 rotates, the rotating block 41 drives the connecting column 51 to rotate. The connecting column 51 is fixed to the limiting rod 52 through the fixing rod 53, and the limiting rod 52 is respectively connected to connecting rods 54 on both sides. The connecting rods 54 are rotatably set on the support plate 3. When the connecting column 51 rotates, the connecting column 51 drives the limiting rod 52 to make the connecting rod 54 rotate on the support plate 3. The stability of the connecting column 51 during the rotation process can be guaranteed by fixing the support plate 3. At the same time, the brake caliper can be fixed by the clamping piece 55 set at the top of the connecting column 51 to prevent the brake caliper from shaking and disengaging due to the rotation of the connecting column 51.

[0038] The clamping member 55 includes a U-shaped clamping block 551, a compression spring 552 and a clamping plate 553. The U-shaped clamping block 551 is arranged at one end of the connecting column 51, and the clamping plates 553 are symmetrically arranged on both sides of the U-shaped clamping block 551. The clamping plate 553 is connected to the U-shaped clamping block 551 through the compression spring 552, and an inclined surface is provided on the clamping plate 553. During operation, when the bottom end of the brake caliper squeezes the inclined surface on the clamping plate 553, the clamping plate 553 will move toward the U-shaped clamping block 551. At this time, the clamping plate 553 squeezes the compression spring 552. When the bottom end of the brake caliper contacts the bottom end of the U-shaped clamping block 551, the compression spring 552 squeezes the clamping plate 553 due to its elastic potential energy to fix the brake caliper.

[0039] The flow control component 6 includes a mounting plate 61, a flow control blade 62, a moving column 63, a moving block 64, and a control spring 65. The mounting plate 61 is symmetrically arranged on both sides of the control component 5, and the end of the mounting plate 61 away from the control component 5 is connected with a moving column 63, and the moving column 63 is arranged in a limiting groove 161 provided on the atomization chamber 16. A plurality of flow control blades 62 are arranged on the mounting plate 61, and a moving block 64 is installed below the mounting plate 61. The moving block 64 is slidably connected to the bottom surface of the atomization chamber 16, and the moving block 64 is an L-shaped structure. One end of the moving block 64 is connected to one end of the atomization chamber 16 through the control spring 65. The contact part of the moving block 64 and the swing plate 42 is the same arc structure. The swing plate 42 rotates to drive the moving block 64 to move, and the displacement of the moving block 64 drives the flow control blade 62 on the mounting plate 61 to move.

[0040] During operation, when the swing plate 42 rotates and pushes the moving block 64 to move toward the two sides of the atomizing chamber 16, the atomizing chamber 16 squeezes the control spring 65 to move toward the two sides of the atomizing chamber 16. At this time, the moving block 64 moves toward one side of the atomizing chamber 16 to drive the mounting plate 61 to move up and down. The moving column 63 provided on one side of the mounting plate 61 moves in the limiting groove 161 provided on the atomizing chamber 16, thereby ensuring the stability of the mounting plate 61 during movement and avoiding the deviation of the mounting plate 61 when it moves up and down. When moving up and down, the mounting plate 61 drives the flow control blade 62 to swing. The swing of the flow control blade 62 can push the salt mist in the atomization chamber 16 into the brake caliper. At the same time, the contact part of the moving block 64 and the swing plate 42 is an arc-shaped structure, which cooperates with the arc shapes on both sides of the swing plate 42. It can avoid the swing plate 42 and the moving block 64 from getting stuck when they contact, thereby ensuring the stability of the moving block 64 during the movement process. At the same time, one end of the moving block 64 with an L-shaped structure can increase the contact area between the compression spring 552 and the moving block 64.

[0041] refer to Figure 7 , Figure 8 As shown, a frustum protrusion 611 is provided below the mounting plate 61, and a plurality of adjustment grooves 641 are provided on the moving block 64, and the shape of the adjustment grooves 641 is consistent with the shape of the frustum protrusion 611, and the adjustment grooves 641 cooperate with the frustum protrusion 611, and the displacement of the moving block 64 drives the mounting plate 61 to reciprocate up and down. Through such a configuration, when the moving block 64 is displaced to one side of the atomization chamber 16, the frustum protrusion 611 provided below the mounting plate 61 is squeezed by the adjustment grooves 641 on the moving block 64, so that the mounting plate 61 reciprocates up and down. At the same time, the plurality of adjustment grooves 641 can realize that the moving block 64 can drive the mounting plate 61 to reciprocate up and down multiple times in one movement cycle, so that the flow control blade 62 can swing multiple times, so that the salt mist in the atomization chamber 16 moves into the groove provided on the brake caliper, thereby ensuring that the inside of the brake caliper is filled with salt mist.

[0042] The flow control blade 62 array is arranged on the mounting plate 61, and the flow control blade 62 is provided with multiple groups. The flow control blade 62 is rotatably arranged on the mounting plate 61. The middle position of the flow control blade 62 is arc-shaped. The rotatably arranged flow control blade 62 can swing greatly when the mounting plate 61 moves up and down, thereby accelerating the flow of salt mist in the atomization chamber 16 to the inside of the brake caliper. At the same time, the arc shape in the middle of the flow control blade 62 can prevent the salt mist in the atomization chamber 16 from flowing over the surface of the flow control blade 62 instead of flowing into the inside of the brake caliper when the flow control blade 62 swings, so that the flow control blade 62 can guide the salt mist.
