Description

Technical Field

[0001] This utility model relates to the field of brake pad testing technology, and in particular to a brake testing device. Background Technology

[0002] A brake is a device that has the function of slowing down, stopping, or keeping a moving part stationary. One step in brake testing is to check whether cracks appear on the surface after emergency braking.

[0003] A search revealed Chinese patent CN215598695U, which discloses a brake testing device. This patent uses a structure where a rotating shaft is fixed to the output end of a motor, a fixing plate is fixed to one end of the motor shaft, and a brake pad is fixed to the other end of the fixing plate via a fixing assembly. This structure aims to test the performance of the brake pads inside the brake. However, when the motor stops working, the brake, under inertia, rotates along with the motor shaft. Prolonged operation can cause the motor shaft to deform, bend, or even break. To advance industry technology, better realize the brake testing function, and improve core technological competitiveness, this application proposes a new implementation scheme for a brake testing device that differs from existing technologies. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when an existing motor stops working, the brake rotates along with the motor shaft due to inertia, and a brake testing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A brake testing device includes a testing box. A mounting bracket is fixedly connected to the bottom inner wall of the testing box, and a protective box is fixedly connected to the top of the mounting bracket. Multiple heat dissipation holes are provided on opposite sides of the protective box. A motor is fixedly connected to the bottom inner wall of the protective box. The motor includes a motor spindle, which is located at one end of the motor. A mounting ring is fixedly connected to one end of the motor spindle. Multiple mounting grooves are provided on the outer circumference of the mounting ring. A top block is slidably connected within each mounting groove. Two first springs are fixedly connected to one side of each top block, and the other ends of the first springs are connected to the mounting grooves. The inner wall is fixedly connected, and one side of the mounting ring is provided with multiple first locking holes. One side of the top block is provided with a sliding hole. A limit pin is slidably connected in the sliding hole. The limit pin is engaged with the first locking holes. One end of the limit pin is fixedly connected with a second spring. The other end of the second spring is fixedly connected to the inner wall of one end of the sliding hole. One end of the motor spindle is sleeved with a rotating ring through a bearing. The inner circumference of the rotating ring is provided with multiple locking grooves. The top block is engaged with the locking grooves. One side of the rotating ring is fixedly connected with a support plate. One side of the support plate is inserted with a fixing bolt. One end of the fixing bolt is threadedly connected to a limit ring.

[0007] Furthermore, the outer circumferential wall of the limiting ring is provided with multiple second locking holes, a connecting block is fixedly connected to one side of the support plate, and an adjusting bolt is threadedly connected to the top of the connecting block, with one end of the adjusting bolt engaging with the second locking holes.

[0008] Furthermore, an electric telescopic rod is fixedly connected to the top outer wall of the testing box, and the bottom end of the electric telescopic rod extends into the testing box and is fixedly connected to a connecting seat. A brake pad is fixedly connected to the bottom of the connecting seat.

[0009] Furthermore, a collection box is slidably inserted into one side of the detection box, and multiple drainage holes are provided on the bottom inner wall of the detection box, with the drainage holes located above the collection box.

[0010] Furthermore, the top outer wall of the testing box is fixedly connected to two water outlet pipes by pipe clamps. Multiple nozzles are threaded to the bottom of the water outlet pipes, and the top of the two water outlet pipes are sealed with the same water inlet pipe.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By driving the support plate and rotating ring to rotate under the inertia of the brake rotation, and then under the guidance of the first and second inclined surfaces, the top block is separated from the slot, thereby disengaging the motor spindle from the rotating ring, thus avoiding damage to the motor spindle caused by the inertia of the brake rotation, and preventing deformation and breakage of the motor spindle.

[0016] 2. By pumping water from the outside into the inlet pipe and then into the nozzle through the outlet pipe, the water is sprayed from the nozzle onto the brake, thereby cooling the brake and improving cooling efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-7 A brake testing device includes a testing box 1. A mounting bracket 5 is fixed to the bottom inner wall of the testing box 1 by bolts. A protective box 6 is fixed to the top of the mounting bracket 5 by bolts. Multiple heat dissipation holes are provided on both sides of the protective box 6. A motor 7 is fixed to the bottom inner wall of the protective box 6 by bolts. The heat generated by the motor 7 is dissipated from the heat dissipation holes.

[0028] The motor 7 includes a motor spindle 701, which is located at one end of the motor 7. A mounting ring 8 is welded to one end of the motor spindle 701. The outer circumferential wall of the mounting ring 8 is provided with multiple mounting grooves 9. A top block 10 is slidably connected in the mounting groove 9. Two first springs 11 are welded to one side of the top block 10. The other end of the first spring 11 is fixedly connected to the inner wall of the mounting groove 9. A plurality of first locking holes 13 are provided on one side of the mounting ring 8. A sliding hole is provided on one side of the top block 10. A limit pin 12 is slidably connected in the sliding hole. The limit pin 12 is engaged with the first locking holes 13. A second spring 1101 is welded to one end of the limit pin 12. The other end of the second spring 1101 is fixedly connected to the inner wall of one end of the sliding hole.

[0029] One end of the motor spindle 701 is connected to a rotating ring 14 via a bearing sleeve. The inner circumference of the rotating ring 14 is provided with multiple slots 15. The top block 10 engages with the slots 15. Under the inertia of the brake rotation, the support plate 16 and the rotating ring 14 rotate, thereby separating the top block 10 from the slots 15. Then, under the pressure of the rotating ring 14, the top block 10 moves inward, thereby squeezing the top block 10 into the mounting groove 9 until the limiting pin 12 aligns with the first locking hole 13. Under the elastic action of the second spring 1101, the limiting pin 12 engages with the first locking hole 13, thereby fixing the top block 10 and disconnecting the motor spindle 701 from the rotating ring 14, thus preventing damage to the motor spindle 701 caused by the inertia of the brake rotation. A support plate 16 is welded to one side of the rotating ring 14. Driven by the motor 7, the motor spindle 701 rotates, thereby driving the mounting ring 8, the rotating ring 14, and the support plate 16 to rotate, and thus driving the brake to rotate.

[0030] A fixing bolt 17 is inserted into one side of the support plate 16. One end of the fixing bolt 17 is threadedly connected to a limit ring 20. The brake is then placed against the support plate 16. The fixing bolt 17 is then passed through the brake and the support plate 16. Finally, the limit ring 20 is tightened to one end of the fixing bolt 17, thereby fixing the brake to one side of the support plate 16.

[0031] The outer circumferential wall of the limiting ring 20 is provided with multiple second locking holes 2001. A connecting block 18 is welded to one side of the support plate 16. An adjusting bolt 19 is threadedly connected to the top of the connecting block 18. One end of the adjusting bolt 19 is engaged with the second locking hole 2001. Tightening the adjusting bolt 19 makes its bottom end engage with the second locking hole 2001, thereby reinforcing the fixation of the brake.

[0032] An electric telescopic rod 3 is fixed to the top outer wall of the test box 1 by bolts. The bottom end of the electric telescopic rod 3 extends into the test box 1 and is fixed to a connecting seat 301 by bolts. A brake pad 302 is fixed to the bottom of the connecting seat 301 by bolts. Under the extension of the electric telescopic rod 3, the connecting seat 301 moves downward, thereby causing the brake pad 302 to contact the brake, and thus perform emergency braking on the brake.

[0033] Two water outlet pipes 401 are fixedly connected to the top outer wall of the test box 1 by pipe clamps. Multiple nozzles are threaded to the bottom of the water outlet pipes 401. The top of the two water outlet pipes 401 is sealed with the same water inlet pipe 4. The other end of the water inlet pipe 4 passes through the top of the test box 1. Under the action of the pump, external water is input into the water inlet pipe 4, and then input into the nozzles through the water outlet pipes 401. Then, the water flow is sprayed from the nozzles to the brake, thereby cooling the brake. A collection box 101 is slidably inserted into one side of the test box 1. Multiple drain holes 102 are provided on the bottom inner wall of the test box 1. The drain holes 102 are located above the collection box 101. Sewage is discharged from the drain holes 102 into the collection box 101 for collection.

[0034] A sealing door 2 is rotatably connected to one side of the test box 1. An observation window 202 is embedded in one side of the sealing door 2. The brake is inspected by observing whether there are cracks in the brake. A handle 203 is fixed to one side of the outer wall of the sealing door 2 by bolts, so as to facilitate the opening and closing of the sealing door 2. A control panel 204 is fixed to one side of the outer wall of the sealing door 2 by bolts. The control panel 204 is electrically connected to the electric telescopic rod 3 and the motor 7. A first inclined surface 1001 is provided on one side of the top block 10, and a second inclined surface 1401 is provided on one side of the inner wall of the slot 15.

[0035] The working principle of this embodiment is as follows: When in use, one end of the water inlet pipe 4 is connected to the water outlet of the pump body, and the water inlet of the pump body is connected to the water storage tank. First, open the sealing door 2 and place the brake against the support plate 16. Then, pass the fixing bolt 17 through the brake and the support plate 16, and tighten the limiting ring 20 to one end of the fixing bolt 17, thereby fixing the brake to one side of the support plate 16. Next, tighten the adjusting bolt 19 so that its bottom end is engaged with the second locking hole 2001, thereby strengthening the fixing of the brake. At this time, the top block 10 is engaged with the locking groove 15, and the motor spindle 701 is connected to the rotating ring 14. Then, start the motor 7 through the control panel 204. Under the drive of the motor 7, the motor spindle 701 rotates, thereby driving the mounting ring 8, the rotating ring 14 and the support plate 16 to rotate, and thus driving the brake to rotate.

[0036] During the rotation of the brake, the electric telescopic rod 3 is activated via the control panel 204. The extension of the electric telescopic rod 3 causes the connecting seat 301 to move downwards, thereby causing the brake pads 302 to contact the brake, thus applying emergency braking. During braking, external water is pumped into the inlet pipe 4 by the pump body, and then into the nozzle via the outlet pipe 401. The water then sprays from the nozzle onto the brake, cooling it. Next, wastewater is discharged from the drain hole 102 into the collection box 101 for collection. Then, the motor 7 stops working, and the inertia of the brake rotation causes the support plate 16 and the rotating ring 14 to rotate. Then, the first inclined plane 1001 and the second inclined plane... Under the guidance of 1401, the top block 10 is separated from the slot 15. Then, under the pressure of the rotating ring 14, the top block 10 moves inward, so that the top block 10 is squeezed into the mounting groove 9 until the limiting pin 12 is aligned with the first locking hole 13. Under the elastic action of the second spring 1101, the limiting pin 12 is engaged with the first locking hole 13, thereby fixing the top block 10. This disengages the motor spindle 701 from the rotating ring 14, thus preventing damage to the motor spindle 701 caused by the inertia of the brake rotation. Then, the brake is inspected through the observation window 202 to see if there are any cracks. If there are cracks, the brake is unqualified; otherwise, it is qualified. This is how the brake is tested.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
