Detailed Implementation

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] Please see Figures 1-5 This utility model discloses a brake spring force testing device, including a control console 1 and a bracket 2 disposed above the control console 1, and further including a spring placement assembly 3, a spring fixing assembly 4, a pressure detection assembly 5, and a lifting assembly 6, wherein:

[0024] The control console 1 is equipped with a display screen 11 and a data input key 12. The bracket 2 is fixed to the top surface of the control console 1 with screws. Specifically, the maximum pressure value that the control console 1 can receive can be preset through the data input key 12 to prevent overpressure from damaging the spring.

[0025] Please refer to the appendix. Figure 3 The spring fixing assembly 4 includes a fixing side plate 41, which is penetrated by a spiral shaft 42 and rotates in a spiral manner. One end of the spiral shaft 42 is provided with a knob 43, and the other end is fitted with a clamping plate 44 and rotates in a spiral manner.

[0026] Please refer to the appendix. Figure 4 The pressure detection component 5 includes a pressure head 51, which is locked to the bottom of the pressure sensor 52 through a threaded hole. The top of the pressure sensor 52 is fixed to the bottom of the mounting plate 53 by bolts. Specifically, the pressure sensor 52 monitors the pressure of the pressure head 51 in real time and records the elastic force data of the spring 34 with high accuracy.

[0027] A crossbeam 411 is welded between the fixed side plates 41. A scale 45 is fixed to the center of the top surface of the crossbeam 411 by screws. Specifically, the scale 45 can quickly confirm the distance of movement of the clamping plate 44, ensuring that the movement distance of the clamping plates 44 on both sides is equal, so that the spring 34 is fixed in the center position.

[0028] In this embodiment, the rotating knob 43 and the fixed side plate 41 are displaced relative to each other by the helical force, which in turn drives the clamping plates 44 on both sides to move towards each other along the sliding shaft 46, thereby stably clamping the spring 34 and waiting for the elastic force to be detected. Example 2

[0029] Based on the above embodiment 1, please refer to the appendix. Figure 2 as well as Figure 5 The spring placement assembly 3 includes a placement groove 31, a mounting base 32 is fixed to the bottom of the placement groove 31 by bolts, a spring groove 33 is provided on the top of the mounting base 32, and a spring 34 is provided on the spring groove 33.

[0030] Fixed side plates 41 are symmetrically arranged on both sides of the placement groove 31. Sliding shafts 46 are symmetrically welded between the fixed side plates 41. The sliding shafts 46 pass through the clamping plate 44 and slide in fit. A rubber pad 47 is provided on one side of the clamping plate 44. Specifically, the rubber pad 47 can protect the spring 34 and prevent the clamping plate 44 from damaging the spring when clamping it.

[0031] The bottom of the control console 1 is provided with several support columns 13, and the bottom of the support columns 13 is provided with anti-slip pads 14. Specifically, the stability of the equipment is improved by the support columns 13 and the anti-slip pads 14, and the equipment is prevented from shaking during use.

[0032] The lifting assembly 6 includes an electric telescopic rod 61, which is fixed to the bracket 2 by bolts.

[0033] An installation plate 53 is welded to the bottom of the electric telescopic rod 61. Sleeves 62 are provided at the four corners of the top surface of the installation plate 53. The sleeves 62 are fitted into the guide rod 63 and slide together. A bracket 2 is welded to the top of the guide rod 63. Specifically, when the electric telescopic rod 61 moves the installation plate 53 up and down, the guide rod 63 is moved to slide in the sleeve 62, thereby limiting the installation plate 53, improving the stability of the up and down movement of the installation plate 53, and thus improving the detection accuracy.

[0034] In this embodiment, the electric telescopic rod 61 extends and drives the mounting plate 53 to move downward. The mounting plate 53 drives the pressure sensor 52 and the pressing head 51 to move downward. Then, the pressing head 51 abuts against the spring 34 and begins to compress the spring 34 downward.

[0035] The working principle and usage process of this utility model are as follows: First, place the spring 34 into the spring groove 33. Rotate the knob 43 according to the size of the spring 34. The knob 43 and the fixed side plate 41 will move relative to each other through the spiral force, thereby driving the clamping plates 44 on both sides to move towards each other along the sliding shaft 46. With the help of the scale 45, quickly confirm the distance of movement of the clamping plates 44 to ensure that the movement distance of the clamping plates 44 on both sides is equal, thereby stably fixing the spring 34 in the center of the spring groove 33 and waiting for the pressure test.

[0036] Then, the electric telescopic rod 61 is activated. The electric telescopic rod 61 extends and moves the mounting plate 53 downward. The mounting plate 53 moves the pressure sensor 52 and the pressure head 51 downward. Then, the pressure head 51 abuts against the spring 34 and begins to squeeze the spring 34 downward. The spring 34 is compressed and gives the pressure head 51 a reaction force. The pressure head 51 transmits the pressure to the pressure sensor 52. The pressure sensor 52 detects the pressure value in real time and transmits the data to the control console 1.

[0037] When the pressure received by the control console 1 reaches the set value, the control console 1 controls the electric telescopic rod 61 to stop working. At this time, the operator can read the spring force data from the display screen 11 of the control console 1. After the test is completed, the electric telescopic rod 61 drives the lower pressure head 51 to move upward, releasing the spring 34. Then, the knob 43 is rotated to release the clamp 44, and the spring 34 can be removed.
