Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to a fatigue running-in test bench. Background Art

[0002] The existing publication number: CN219573478U, discloses a mechanical running-in detection device, which is provided by arranging a turntable at the end of the motor rotating shaft and a wedge block on the upper surface of the turntable. A roller is provided on the lower surface of the detection frame corresponding to the wedge block. The detection frame can be driven to rise and fall back and forth through the cooperation between the wedge block and the roller, thereby realizing the wear resistance detection of the mechanical parts inside the detection frame and testing the running-in degree of the mechanical parts. When the mechanical parts are loose, etc., they can be detected in time to ensure the factory quality of the product.

[0003] However, when the above-mentioned equipment is actually used, the mechanical parts to be tested will swing back and forth in the detection frame, causing friction with the inner wall of the detection frame and even scratching the inner wall of the detection frame. Such scratches and wear may produce sharp edges, causing the staff to be at risk of being scratched when taking and placing the mechanical parts. Frequent scratches and wear will also shorten the service life of the detection frame, causing the inside of the detection frame to be uneven, affecting the accuracy of the running-in test results.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] When the detection frame of existing equipment is in actual use, the mechanical parts to be tested will swing back and forth in the detection frame and rub against the inner wall of the detection frame, and even scratch the inner wall of the detection frame. Such scratches and wear may produce sharp edges, causing the staff to be at risk of being scratched when taking and placing mechanical parts. Frequent scratches and wear will also shorten the service life of the detection frame, causing the inside of the detection frame to be uneven, affecting the accuracy of the running-in test results.

[0023] To resolve the defects in the use of the above equipment, please refer to Figure 1-Figure 5 The utility model provides a fatigue running-in test bench, which can replace the inner frame 32 on the detection frame 3 when the detection frame 3 is damaged to a certain extent, thereby extending the service life of the detection frame 3. The test bench is based on a test bench 1. A slide 2 is symmetrically installed on the top of the test bench 1. A detection frame 3 is arranged between the two slides 2. The detection frame 3 includes an outer frame 31 slidably installed between the two slides 2. An inner frame 32 is installed inside the outer frame 31, and connecting pieces 33 are symmetrically arranged between the outer frame 31 and the inner frame 32. Both ends of the test bench 1 are provided with a testing mechanism 4 that drives the outer frame 31 to slide up and down along the slide 2. The inner frame 32 is movably installed inside the outer frame 31. During testing, mechanical components are placed in the inner frame 32. When the detection frame 3 is used for a certain period of time and the inner frame 32 is scratched by mechanical components, the inner frame 32 can be removed by the connecting piece 33 and a new inner frame 32 can be installed to ensure the flatness of the inside of the inner frame 32, prevent staff from being scratched by scratches on the inner frame 32, and extend the service life of the detection frame 3.

[0024] The cam 332 is fixedly secured to the cam 334 by the spring 336 so as to allow the cam 333 to slide in and out of the cam 336. The cam 332 is then retracted to allow the cam 333 to slide in and out of the cam 336.

[0025] The inner frame 32 may automatically rotate in the outer frame 31 during the shaking process, causing the insertion rod 333 to automatically fall off from the mounting box 334, thereby affecting the stability of the connection between the inner frame 32 and the outer frame 31. In order to solve this technical problem, a limiting rod 335 is slidably installed at the bottom of the mounting box 334, and a limiting groove 337 is provided on the insertion rod 333 to match the limiting rod 335. A connecting spring 336 is provided on the outer sleeve of the limiting rod 335, and the limiting rod 335 is A pull rod is installed at the lower end, the upper end of the connecting spring 336 is fixedly connected to the bottom of the installation box 334, and the lower end of the connecting spring 336 is fixedly connected to the lower end of the limiting rod 335. The limiting rod 335 can be inserted into the limiting groove 337 through the elastic force of the connecting spring 336. The limiting rod 335 can limit the rotation of the insertion rod 333, thereby preventing the inner frame 32 from rotating automatically and enhancing the stability of the installation of the inner frame 32. When replacing the inner frame 32, pull the pull rod to drive the limiting rod 335 to slide out of the limiting groove 337, and then the inner frame 32 can be rotated to remove it.

[0026] Although the existing equipment can drive the detection frame 3 to shake up and down to test the mechanical parts, the shaking amplitude of the detection frame 3 is fixed. When testing different mechanical parts, it may be necessary to apply different shaking amplitudes. A bracket 41 is fixedly mounted on the test bench 1, and a servo motor 42 is mounted on one side of the bracket 41. The output end of the servo motor 42 is fixedly connected to a turntable 43, and the turntable 43 is rotatably mounted on the bracket 41. A connector 44 is slidably mounted on one side of the turntable 43, and a connecting rod 45 is rotatably mounted on one side of the connecting rod 44. A connecting shaft 46 is fixedly mounted on the side of the outer frame 31 close to the test mechanism 4, and one end of the connecting rod 45 is rotatably sleeved on the connecting shaft 46. A screw rod 47 is also rotatably installed on one side of 43, and a connecting head 44 is threadedly connected to the outside of the screw rod 47, and a knob is installed on one end of the screw rod 47, which drives the servo motor 42 to drive the turntable 43 to rotate. The rotation of the turntable 43 drives the connecting head 44 to rotate, and the rotation of the connecting head 44 pulls the outer frame 31 up and down through the connecting rod 45. By rotating the screw rod 47, the connecting head 44 can be driven to slide on the turntable 43 to adjust the position of the connecting head 44. By adjusting the distance between the connecting head 44 and the center of the turntable 43, the distance that the connecting rod 45 drives the outer frame 31 to slide up and down can be adjusted, thereby controlling the shaking amplitude of the detection frame 3, so that the equipment can test different types of mechanical components.

[0027] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0028] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
