Description

Technical Field

[0001] This utility model relates to the field of housing inspection technology, and in particular to a pressure resistance testing device for a reducer housing. Background Technology

[0002] The compressive strength test of the reducer housing is a key quality control step to ensure its structural integrity and safety. This usually refers to the static compressive strength test, which simulates the housing's ability to resist deformation and rupture under extreme loads. When the pressure on the housing exceeds its ultimate strength and a sudden and violent rupture occurs, the resulting high-speed fragments or pieces are ejected outwards, creating a dangerous phenomenon.

[0003] A search revealed Chinese patent publication number CN221765129U, which discloses a battery casing pressure resistance testing device. This patent uses a hydraulic cylinder to extend and retract, causing a protruding rod on a pressure plate to move downwards and press the battery casing for testing. Simultaneously, the pressure plate moves a connecting rod to lower a hinge seat, which in turn moves a movable rod to move a hinge seat, causing the protective plates to move towards each other and enclose the battery casing, preventing debris from flying out during testing and causing injury to the testing personnel. However, this device has certain problems: the casing may break during testing, requiring workers to clean the debris from the pad. This requires reaching under the pressure plate to clean, posing a safety hazard and affecting testing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a pressure resistance testing device for a reducer housing in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A pressure resistance testing device for a reducer housing includes a workbench, a protective mechanism on the workbench, a pad hinged to the upper end of the workbench, and a feeding mechanism behind the pad.

[0007] The feeding mechanism includes a fixed block, which is fixedly connected to the rear end of the worktable. Symmetrical electric push rods are fixedly connected to the front end of the fixed block. Push blocks are fixedly installed at the front end of the electric push rods. The end of the push block near the pad is inclined. Multiple rollers are rotatably connected to the inclined surface of the push block. Multiple protrusions are fixedly connected to the lower end of the pad. The multiple protrusions are located on the side of the pad near the push block.

[0008] Preferably, the front end of the workbench is provided with a sliding groove, and a collection box is slidably connected to the sliding groove. The collection box is located in front of the pad.

[0009] Preferably, the protective mechanism includes two grooves, which are symmetrical about the pad, and a bidirectional lead screw is rotatably connected within the grooves.

[0010] Preferably, the two-way lead screw has symmetrical protective plates threaded on both sides, and a power motor is fixedly installed on one side of the worktable, with the output shaft of the power motor fixedly connected to the two-way lead screw.

[0011] Preferably, the protective plate is slidably connected in the groove, and the symmetrical protective plate is U-shaped with the opening facing the pad.

[0012] Preferably, a fixed frame is fixed at the upper end of the workbench. The fixed frame is U-shaped with the opening facing downwards, and a hydraulic cylinder is fixedly installed at the upper end of the fixed frame.

[0013] Preferably, the output shaft of the hydraulic cylinder is fixedly connected to a connecting plate, and a pressure plate is fixed to the lower end of the connecting plate.

[0014] The beneficial effects are as follows: after the shell breaks, the electric push rod is activated to push the push block close to the pad, so that the push block lifts the lower end of the pad. Then the roller and the pad roll together, causing the rear end of the pad to tilt up. At this time, the shell fragments on the pad move towards the front end of the pad. At the same time, the roller and the protrusion roll together, causing the pad to vibrate. As the rear end of the pad tilts up, all the fragments are shaken off.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a pressure resistance testing device for a reducer housing includes a workbench 101, a protective mechanism on the workbench 101, a pad 103 hinged to the upper end of the workbench 101, and a feeding mechanism behind the pad 103.

[0027] The unloading mechanism includes a fixed block 401, which is fixedly connected to the rear end of the worktable 101. Symmetrical electric push rods 402 are fixedly connected to the front end of the fixed block 401. A push block 403 is fixedly installed at the front end of each electric push rod 402. The end of the push block 403 near the pad 103 is inclined. Multiple rollers 404 are rotatably connected to the inclined surface of the push block 403. Multiple protrusions 405 are fixedly connected to the lower end of the pad 103, located on the side of the pad 103 near the push block 403. During use, the housing is placed on the pad 103, and then... The protective mechanism encloses the shell to prevent flying fragments from injuring people when the shell breaks. When the shell breaks, the electric push rod 402 is activated to push the push block 403 close to the pad 103, so that the push block 403 scoops up the lower end of the pad 103. Then, the roller 404 rolls with the pad 103, causing the rear end of the pad 103 to tilt up. At this time, the shell fragments on the pad 103 move towards the front end of the pad 103. At the same time, the roller 404 and the protrusion 405 roll, causing the pad 103 to vibrate, so that all the fragments are shaken off during the process of the rear end of the pad 103 tilting up.

[0028] The front end of the workbench 101 is provided with a sliding groove 601, and a collection box 602 is slidably connected to the sliding groove 601. The collection box 602 is located in front of the pad 103. The fragments on the pad 103 fall into the collection box 602. As the number of shell fragments gradually increases, the collection box 602 is pulled forward, causing the collection box 602 to slide with the sliding groove 601, thereby removing the collection box 602 for cleaning.

[0029] The protective mechanism includes two grooves 201, which are symmetrical about the pad 103. A bidirectional lead screw 202 is rotatably connected inside the grooves 201.

[0030] The two-way lead screw 202 has symmetrical protective plates 301 threadedly connected to both sides. A power motor 302 is fixedly installed on one side of the worktable 101. The output shaft of the power motor 302 is fixedly connected to the two-way lead screw 202. The power motor 302 drives the two-way lead screw 202 to rotate, so that the two-way lead screw 202 and the protective plates 301 are threadedly engaged, causing the protective plates 301 on both sides to move towards each other.

[0031] The protective plate 301 is slidably connected in the groove 201, and the symmetrical protective plate 301 is U-shaped with its opening facing the pad 103.

[0032] A fixed frame 102 is fixed to the upper end of the workbench 101. The fixed frame 102 is U-shaped with the opening facing downwards. A hydraulic cylinder 501 is fixedly installed on the upper end of the fixed frame 102.

[0033] The output shaft of the hydraulic cylinder 501 is fixedly connected to the connecting plate 502, and the lower end of the connecting plate 502 is fixed with the pressure plate 503. The hydraulic cylinder 501 drives the connecting plate 502 to descend, so that the connecting plate 502 drives the pressure plate 503 to squeeze the shell.

[0034] Working principle: During use, the housing is placed on the pad 103. Then, the power motor 302 drives the double-acting screw 202 to rotate, causing the screw 202 to engage with the protective plate 301. This causes the protective plates 301 on both sides to move towards each other, enclosing the housing and preventing injury from flying fragments if the housing breaks. The hydraulic cylinder 501 drives the connecting plate 502 to descend, causing the connecting plate 502 to drive the pressure plate 503 to squeeze the housing. When the housing breaks, the power motor 302 drives the protective plates 301 away from the pad 103, activating the electric push rod 402 to push the push block 403 closer to the pad 103, causing... The pusher 403 lifts the lower end of the pad 103, and then the roller 404 rolls with the pad 103, causing the rear end of the pad 103 to tilt upwards. At this time, the shell fragments on the pad 103 move towards the front end of the pad 103. At the same time, the roller 404 and the protrusion 405 roll, causing the pad 103 to vibrate. As the rear end of the pad 103 tilts upwards, all the fragments are shaken off and fall into the collection box 602. As the number of shell fragments gradually increases, the collection box 602 is pulled forward, causing the collection box 602 to slide with the sliding groove 601, thereby removing the collection box 602 for cleaning.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
