Description

Technical Field

[0001] This utility model relates to the field of impact testing technology, specifically to a mechanical impact testing bench. Background Technology

[0002] Currently, in the quality inspection process of many products, it is essential to measure the impact resistance of the product. Impact collision test benches are used in the laboratory to simulate the impact damage that a product needs to withstand in actual use, so as to evaluate the impact resistance of the product structure and optimize the product structure strength through test data.

[0003] For example, Chinese patent publication number CN 209264237 U discloses a protective mechanical impact testing bench, including a base, a support plate mounted on the base, a support platform for preventing impact on the workpiece mounted at the center of the support plate, four sliding rods mounted on the support plate and vertically symmetrically located on the outer side of the support platform, and a connecting frame for mounting the tops of the sliding rods; the connecting frame is equipped with a double-ear support and a servo motor, and also includes a servo telescopic cylinder for buffering, a lever, and an elastic top member. In this application, the servo telescopic cylinder controls and cooperates with the elastic top member at one end of the lever to buffer and block the secondary falling connecting plate and impact head, preventing the impact on the measurement of the workpiece. Furthermore, the buffer spring and T-shaped member can prevent direct impact on the lever, thereby protecting the lever and the servo telescopic cylinder.

[0004] However, this mechanical impact testing bench still has shortcomings in actual use. For example, it lacks necessary protective measures. During impact testing, the product is easily damaged by the impact head, resulting in flying fragments. Once the flying fragments come into contact with the human body, they can easily cause injury to the workers. At the same time, during multiple impacts, the traction rope is frequently raised and lowered, which will cause wear on the traction rope and reduce its service life. Utility Model Content

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1-5 As shown, the present invention provides a technical solution including a housing assembly 1, an impact assembly 2 on the top of the housing assembly 1, and a lubrication assembly 3 on one side of the top inside the housing assembly 1.

[0028] The housing assembly 1 includes a protective housing 101, a test chamber 102 is provided inside the protective housing 101, an opening is provided in the middle of the top surface of the protective housing 101, a roller 103 is provided in the opening, an inlet and outlet 105 is provided at the bottom of the front of the protective housing 101, a sealing plate 106 is slidably installed inside the inlet and outlet 105, a first inclined plate 107 is fixedly installed on one side of the back of the sealing plate 106, a linear motor 108 is fixedly embedded in the middle of the bottom surface of the test chamber 102, a sliding plate 109 is fixedly installed on the top surface of the slider of the linear motor 108, and a second inclined plate 111 is fixedly installed on one edge of the top surface of the sliding plate 109.

[0029] The lubrication assembly 3 includes a mounting plate 301. An oil tank 302 is fixedly mounted on one side of the bottom surface of the mounting plate 301. An oil pump 303 is fixedly mounted on one side of the oil tank 302. An oil delivery pipe 304 is fixedly connected to the output port of the oil pump 303. A sleeve 305 is fixedly mounted on the side of the mounting plate 301 away from the oil tank 302. Lubricating oil nozzles 306 are fixedly embedded around the cylinder body of the sleeve 305. A circular tube 307 is sleeved on the outside of the four lubricating oil nozzles 306.

[0030] In this embodiment, the impact assembly 2 includes a servo motor 201, and a roller 202 is fixedly mounted on one end of the output shaft of the servo motor 201. A traction rope 203 is wound around the roller body of the roller 202.

[0031] An impact head 204 is fixedly installed at the bottom end of the traction rope 203, and a connecting slide bar 205 is fixedly installed on the top side of one side of the impact head 204.

[0032] The linear motor 108 is fixedly installed on the top surface of the protective box 101, the traction rope 203 is attached to the roller 103, and the sleeve 305 is sleeved on the outside of the traction rope 203.

[0033] One end of the oil supply pipe 304 is fixedly connected to the outer side of the circular pipe 307, and one end of each of the four lubricating oil nozzles 306 is fixedly connected to the inner side of the circular pipe 307. The oil pump 303 delivers the lubricating oil in the oil tank 302 to the circular pipe 307, and then inputs it to each lubricating oil nozzle 306 through the circular pipe 307. Finally, the oil is sprayed onto the surface of the traction rope 203 through the lubricating oil nozzles 306, thereby completing the lubrication operation of the traction rope 203.

[0034] A support platform 110 is fixedly installed on the top surface of the slide plate 109. The first inclined plate 107 and the second inclined plate 111 correspond to each other, and their inclined surfaces abut together. Since the inclined surface of the second inclined plate 111 abuts the inclined surface of the first inclined plate 107, the first inclined plate 107 can be lifted up as the second inclined plate 111 moves.

[0035] A vertical sliding groove 104 is provided on one side of the test chamber 102. The end of the connecting rod 205 away from the impact head 204 is slidably installed in the vertical sliding groove 104. The stability of the lifting and lowering of the impact head 204 can be improved by the connecting rod 205.

[0036] Working principle: This system facilitates the loading and unloading of products to be inspected. Specifically, when the linear motor 108 is started, the slide plate 109 moves to the outside of the test chamber 102 under the action of the linear motor 108. The movement of the slide plate 109 drives the second inclined plate 111 to move. Since the inclined surface of the second inclined plate 111 abuts against the inclined surface of the first inclined plate 107, the movement of the second inclined plate 111 pushes the first inclined plate 107 to rise. Finally, the bottom surface of the first inclined plate 107 will overlap the top surface of the second inclined plate 111. The rise of the second inclined plate 111 will drive the sealing plate 106 to rise, thus allowing the slide plate to move freely. As the plate 109 extends out of the test chamber 102, the seal of the inlet and outlet 105 is simultaneously released, making it convenient for staff to place the product to be inspected on the support platform 110. After placement, the sliding plate 109 is controlled to retract the product into the test chamber 102. After the sliding plate 109 retracts to the impact position, the sealing plate 106 will also fall under its own weight and re-close the inlet and outlet 105. This allows the test chamber 102 to be closed during the impact test of the impact component 2, thereby preventing the product surface from being damaged by impact and causing fragments to fly, which could lead to injury to staff. This enhances safety.

[0037] During the impact test, the servo motor 201 drives the roller 202 to rotate. The rotation of the roller 202 causes the traction rope 203 to move up to a certain height. Then, the power is cut off, and the traction rope 203 loses its traction force. The impact head 204 falls freely downward under the action of gravity, so that the product set on the top surface of the support platform 110 can be subjected to an impact test. The position and size of the impact head 204 can be selected according to the actual test requirements.

[0038] Meanwhile, by setting up a sleeve 305, a lubricating oil nozzle 306, an oil tank 302, and an oil pump 303, lubricating oil can be automatically sprayed onto the surface of the traction rope 203 to reduce wear during use. Specifically, the oil pump 303 delivers the lubricating oil in the oil tank 302 to the circular pipe 307, and then inputs it into each lubricating oil nozzle 306 through the circular pipe 307. Finally, the oil is sprayed onto the surface of the traction rope 203 through the lubricating oil nozzle 306, thereby completing the lubrication operation of the traction rope 203.

[0039] In summary, this mechanical impact testing bench can seal the test chamber 102 during impact testing of the impact component 2, thereby preventing the product surface from being damaged by impact and causing fragments to fly, which could lead to injury to workers. This enhances safety. At the same time, by setting up the sleeve 305, lubricating oil nozzle 306, oil tank 302, and oil pump 303, it can automatically spray lubricating oil onto the surface of the traction rope 203, reducing wear on the traction rope 203 during use and extending its service life.

[0040] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
