Description

Technical Field

[0001] This utility model belongs to the field of automotive caliper testing technology, specifically, it relates to a strength testing device for automotive caliper assembly production. Background Technology

[0002] Automotive calipers are important components of the braking system. They are made of high-strength materials and contain pistons. The pressure of brake fluid or gas pushes the brake pads against the brake disc or brake drum, causing the wheels to slow down or stop rotating, thus ensuring the car can safely decelerate or stop.

[0003] Automotive caliper strength testing equipment is a high-precision testing device specifically designed to evaluate the strength and durability of automotive calipers under various working conditions. By simulating real-world working environments and conditions, this equipment ensures the accuracy and reliability of test results.

[0004] Currently, in existing technologies, when performing strength testing on automotive calipers, it is necessary to fix the calipers in a fixed position. Common fixing structures in automotive caliper strength testing equipment include slide rails with two sliding plates connected to them. The two ends of the automotive caliper are fixed to the two sliding plates by screws, and then the locking rods on the sliding plates are tightened to fix the sliding plates to the slide rails, thereby achieving the purpose of fixing the automotive caliper. Although this method can fix the automotive caliper, it involves many steps and is relatively cumbersome, which reduces the testing efficiency of automotive calipers. Utility Model Content

[0005] To address the technical problem of reduced testing efficiency for automotive calipers, this utility model provides a strength testing device for automotive caliper assembly production.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A strength testing device for automotive caliper assembly production includes a base plate; a central rod is connected to the center of the upper surface of the base plate, and a rotating plate is connected to the upper end of the central rod via a bearing; first uprights are connected to the upper surfaces of both ends of the rotating rod; two first movable plates are arranged symmetrically around the central rod on the upper surface of the base plate corresponding to the positions of the rotating plates; a second upright is connected to the upper surface of the first movable plates corresponding to the positions of the first uprights; a pull rod is rotatably connected between the first uprights and the second uprights; a first clamping plate is connected to the upper surface of the first movable plates corresponding to the positions of the central rod; a placement frame is connected to the upper surface of the base plate corresponding to the positions of the central rod; symmetrically arranged second clamping plates are arranged above the placement frame; a movable plate is connected to the surface of the second clamping plate; a second movable plate is connected to the lower surface of the movable plate; a bidirectional screw is rotatably connected to the placement frame corresponding to the positions of the second movable plates; both second movable plates are threadedly connected to the bidirectional screw; one end of the bidirectional screw passes through the placement frame and is connected to a motor fixed to the outside of the placement frame.

[0008] Preferably, a positioning slide plate is connected to the lower surface of the first movable plate, and an I-beam plate is connected to the upper surface of the base plate at the position corresponding to the positioning slide plate, with the positioning slide plate slidably connected inside the I-beam plate.

[0009] Preferably, an auxiliary plate is connected to one end of the first movable plate near the center rod and away from the first clamping plate, and a cylinder is connected to the upper surface of the base plate at the position corresponding to the auxiliary plate, with the cylinder output end connected to the auxiliary plate.

[0010] Preferably, the second clamping plate is rotatably connected to multiple rotating rods on the side near the middle of the placement frame.

[0011] Preferably, the placement frame has symmetrically arranged movable slots at the positions corresponding to the movable plates, the movable plates are slidably connected in the movable slots, and the placement frame has symmetrically arranged positioning rods at the positions corresponding to the two ends of the second movable plates, and both second movable plates are slidably connected to the positioning rods.

[0012] Preferably, an L-shaped bracket is connected to the upper surface of the base plate corresponding to the position of the placement rack, and a third clamping plate is provided on the lower surface of the bracket corresponding to the middle position of the placement rack. Springs are connected to the four corners of the upper surface of the third clamping plate, and connecting plates are connected to the upper ends of the springs. A rack is connected to the middle of the upper surface of the connecting plate, and the rack is slidably connected inside the bracket.

[0013] Preferably, a limiting rod is connected to the upper surface of the third clamp plate at the position corresponding to the spring. The limiting rod is displaced within the spring, and a limiting groove is opened on the connecting plate corresponding to the limiting rod. The limiting rod is slidably connected within the limiting groove.

[0014] Preferably, a gear meshes below the rack, a connecting rod is connected to the middle of the gear on the side away from the motor, a first pulley is connected to the end of the connecting rod away from the gear, and a double-acting screw is connected to a second pulley through the placement frame at the end away from the motor. A belt is rotatably connected between the first pulley and the second pulley.

[0015] The beneficial effects of this utility model are:

[0016] By starting the motor, the motor drives the double-acting lead screw to rotate. During the rotation of the double-acting lead screw, the two second moving plates move closer together, thereby bringing the two second clamping plates closer together. After the two second clamping plates move closer together, they can clamp both ends of the car caliper. Under the action of the rotating rod, the car caliper is restricted in one direction. Furthermore, through the cooperation of the rotating rod, when the two first clamping plates approach and contact the two sides of the car caliper, the position of the car caliper in the other direction can be adjusted. With the cooperation of the first clamping plates, the second clamping plates, and the rotating rod, the car caliper can be fixed in the middle of the mounting frame, which facilitates the inspection of the car caliper, reduces the operation steps, makes the operation simple and convenient, and improves the inspection efficiency.

[0017] By activating the cylinder, the cylinder, in conjunction with the auxiliary plate, pulls one of the first moving plates. This first moving plate, with the cooperation of the positioning slide plate and the I-beam plate, moves closer to the center rod. During this movement, the first moving plate, with the cooperation of the first upright rod, pushes a corresponding pull rod. This pull rod, in conjunction with a corresponding second upright rod, causes the rotating plate to rotate around the center rod. As the rotating plate rotates, it, in conjunction with another second upright rod, pulls another corresponding pull rod. This pull rod, with the cooperation of the first upright rod, pulls another first moving plate. This second moving plate, with the cooperation of the positioning slide plate and the I-beam plate, moves synchronously closer to the center rod. As the two first moving plates move closer to the center rod, the two first clamping plates also move closer simultaneously, thus clamping both sides of the automotive caliper and fixing it in place. This reduces the number of operation steps, making operation simple and convenient, and improving inspection efficiency.

[0018] During rotation, the double-acting screw drives the second pulley to rotate synchronously. The second pulley, in conjunction with the belt and the first pulley, drives the connecting rod and gear to rotate. The rotation of the gear drives the rack rod to descend, which in turn drives the connecting plate and the third clamping plate to descend. After descending, the third clamping plate contacts the top of the car caliper. With the help of the spring, the third clamping plate clamps the top of the car caliper. The cooperation of the first, second, and third clamping plates fully fixes the car caliper, enabling strength testing. This ensures greater stability of the car caliper during strength testing and does not affect the test results. Attached Figure Description

[0032] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1 - Figure 5 As shown, a strength testing device for automobile caliper assembly production includes a base plate 1, with a central rod 2 connected to the middle of the upper surface of the base plate 1 for connecting a rotating plate 21.

[0034] The upper end of the center rod 2 is connected to a rotating plate 21 via a bearing, which is used to synchronously drive the two first clamping plates 26 to move.

[0035] The upper surfaces of both ends of the rotating rod 411 are connected to the first upright rod 22, which is used to assist in pulling the first moving plate 25.

[0036] Two first movable plates 25 are arranged on the upper part of the base plate 1, corresponding to the two sides of the rotating plate 21. The two first movable plates 25 are symmetrically arranged with the central rod 2 as the center. The first movable plates 25 are used to drive the first clamping plate 26 to move.

[0037] A second upright 24 is connected to the upper surface of the first movable plate 25 at the position corresponding to the first upright 22. A pull rod 23 is rotatably connected between the first upright 22 and the second upright 24. The pull rod 23 is used to connect the rotating plate 21 and the first movable plate 25.

[0038] A first clamping plate 26 is connected to the upper surface of the first movable plate 25 at the position corresponding to the center rod 2. The first clamping plate 26 is used to clamp both sides of the car caliper.

[0039] The lower surface of the first movable plate 25 is connected to a positioning slide plate 27, and the upper surface of the base plate 1 is connected to an I-beam plate 28 corresponding to the position of the positioning slide plate 27. The positioning slide plate 27 is slidably connected inside the I-beam plate 28. Through the cooperation of the positioning slide plate 27 and the I-beam plate 28, the position of the first movable plate 25 can be limited to prevent the first movable plate 25 from shifting.

[0040] One of the first movable plates 25 is connected to an auxiliary plate 3 at the end near the center rod 2 and away from the first clamping plate 26. A cylinder 31 is connected to the upper surface of the base plate 1 at the position corresponding to the auxiliary plate 3. The output end of the cylinder 31 is connected to the auxiliary plate 3. The cylinder 31 works with the auxiliary plate 3 to push or pull one of the first movable plates 25.

[0041] In practical use, by activating cylinder 31, cylinder 31, in conjunction with auxiliary plate 3, pulls one of the first moving plates 25. With the cooperation of positioning slide plate 27 and I-beam plate 28, the first moving plate 25 moves closer to the center rod 2. During this movement, one of the first moving plates 25, in conjunction with first upright rod 22, pushes a corresponding pull rod 23. The pull rod 23, in conjunction with a corresponding second upright rod 24, causes rotating plate 21 to rotate around center rod 2. During this rotation, rotating plate 21, in conjunction with another second upright rod 24, pulls another corresponding pull rod 23. This pull rod 23, in conjunction with first upright rod 22, pulls another first moving plate 25. With the cooperation of positioning slide plate 27 and I-beam plate 28, this second first moving plate 25 moves synchronously closer to the center rod 2. As the two first moving plates 25 move closer to the center rod 2, the two first clamping plates 26 also move closer simultaneously, thus clamping both sides of the automotive caliper and fixing it. This reduces the number of operation steps, making operation simple and convenient, and improving testing efficiency.

[0042] A mounting bracket 4 is connected to the upper surface of the base plate 1 at the position corresponding to the center rod 2, for placing car calipers.

[0043] A second clamping plate 41 is symmetrically arranged above the mounting bracket 4 for clamping both ends of the car caliper.

[0044] The second clamping plate 41 is rotatably connected to multiple rotating rods 411 on the side near the middle of the mounting bracket 4, which are used to assist in adjusting the position of the car caliper.

[0045] The second clamping plate 41 is connected to a movable plate 42. The placement rack 4 has symmetrically arranged movable slots 421 at the position corresponding to the movable plate 42. The movable plate 42 is slidably connected in the movable slot 421. Through the cooperation between the movable plate 42 and the movable slot 421, the movement position of the second clamping plate 41 can be limited, so that the second clamping plate 41 can clamp and fix car calipers of different sizes.

[0046] The lower surface of the movable plate 42 is connected to a second movable plate 43. The placement frame 4 is rotatably connected to a bidirectional screw 44 corresponding to the position of the second movable plate 43. Both second movable plates 43 are threadedly connected to the bidirectional screw 44. By rotating the bidirectional screw 44, the two second clamping plates 41 can be moved closer to each other or moved further away from each other.

[0047] One end of the bidirectional lead screw 44 passes through the placement frame 4 and is connected to the motor 45 fixed to the outside of the placement frame 4. The motor 45 is used to drive the bidirectional lead screw 44 to rotate.

[0048] The placement frame 4 is connected to symmetrically arranged positioning rods 46 at both ends of the second movable plate 43. Both second movable plates 43 are slidably connected to the positioning rods 46. The positioning rods 46 are used to limit the position of the second movable plates 43 and prevent the second movable plates 43 from deflecting.

[0049] In practical use, by starting the motor 45, the motor 45 drives the bidirectional lead screw 44 to rotate. During the rotation of the bidirectional lead screw 44, the two second moving plates 43 move closer to each other, thereby bringing the two second clamping plates 41 closer to each other. After the two second clamping plates 41 move closer to each other, they can clamp both ends of the car caliper. Under the action of the rotating rod 411, the car caliper is restricted in one direction. And with the cooperation of the rotating rod 411, when the two first clamping plates 26 approach the two sides of the car caliper and contact the car caliper, the position of the car caliper in the other direction can be adjusted. With the cooperation of the first clamping plates 26, the second clamping plates 41 and the rotating rod 411, the car caliper can be fixed in the middle of the placement frame 4, which facilitates the inspection of the car caliper, reduces the operation steps, makes the operation simple and convenient, and improves the inspection efficiency.

[0050] An L-shaped bracket 5 is connected to the upper surface of the base plate 1 at the position corresponding to the placement rack 4, which is used to support the third clamping plate 54.

[0051] A third clamping plate 54 is provided on the lower surface of the bracket 5 at the position corresponding to the middle of the placement bracket 4. The third clamping plate 54 is used to clamp the top of the car caliper.

[0052] Springs 53 are connected to the four corners of the upper surface of the third clamping plate 54. The springs 53 are used to reset the third clamping plate 54.

[0053] Each spring 53 is connected to a connecting plate 52 at its upper end. A limit rod 55 is connected to the upper surface of the third clamping plate 54 at the position corresponding to the spring 53. The limit rod 55 moves into the spring 53. The connecting plate 52 has a limit groove 56 corresponding to the limit rod 55. The limit rod 55 is slidably connected in the limit groove 56. The limit rod 55 and the limit groove 56 cooperate to limit the position of the spring 53 and prevent the spring 53 from bending and causing the third clamping plate 54 to shift.

[0054] A rack rod 51 is connected to the middle of the upper surface of the connecting plate 52. The rack rod 51 is slidably connected in the bracket 5. A gear 6 meshes below the rack rod 51. A connecting rod 61 is connected to the middle of the side of the gear 6 away from the motor 45. A fixing block 611 is connected to the upper surface of the bracket 5 at the position corresponding to the connecting rod 61. The connecting rod 61 is rotatably connected in the fixing block 611. The fixing block 611 is used to support the connecting rod 61 and fix the position of the connecting rod 61.

[0055] The end of the connecting rod 61 away from the gear 6 is connected to the first pulley 62. The end of the double-acting screw 44 away from the motor 45 passes through the placement frame 4 and is connected to the second pulley 63. A belt 64 is rotatably connected between the first pulley 62 and the second pulley 63. Through the cooperation of the first pulley 62, the second pulley 63 and the belt 64, the gear 6 can be driven to rotate, thereby enabling the third clamping plate 54 to be raised and lowered.

[0056] The bracket 5 has a through groove 641 at the position corresponding to the belt 64. The belt 64 is located in the through groove 641. By opening the through groove 641, the bracket 5 can prevent the belt 64 from being affected by the rotation.

[0057] In practical use, the bidirectional lead screw 44 rotates, which drives the second pulley 63 to rotate synchronously. The second pulley 63, together with the belt 64 and the first pulley 62, drives the connecting rod 61 and the gear 6 to rotate. The rotation of the gear 6 drives the rack rod 51 to descend. The descent of the rack rod 51 drives the connecting plate 52 and the third clamping plate 54 to descend. After the third clamping plate 54 descends, it will contact the top of the car caliper. With the cooperation of the spring 53, the third clamping plate 54 will clamp the top of the car caliper. The cooperation of the first clamping plate 26, the second clamping plate 41 and the third clamping plate 54 makes the car caliper fully fixed, so that the car caliper can be tested for strength. During the strength test, the car caliper is more stable and will not affect the test.

[0058] Working principle:

[0059] The car caliper is placed in the middle of the upper surface of the mounting bracket 4. After placement, the motor 45 is started, so that the second clamping plate 41 clamps both ends of the car caliper and the third clamping plate 54 clamps the upper end of the car caliper. After clamping, the cylinder 31 is started, so that the first clamping plate 26 works with the rotating rod 411 to correct the position of the car caliper and clamp both sides of the car caliper, so that the car caliper is fully fixed, thereby performing strength testing.
