Description

Technical Field

[0001] This utility model relates to the technical field of charging gun pressure withstand clamping test device, specifically a charging gun pressure withstand clamping test device. Background Technology

[0002] The charging gun pressure test clamping device is a special equipment used to test the mechanical strength and structural reliability of the charging gun. It fixes the charging gun with mechanical clamps and applies controllable physical pressure to the charging gun using a hydraulic or pneumatically driven pressing mechanism, while simultaneously monitoring its deformation, cracks and loosening of connecting parts.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following drawbacks often exist: Current charging heads typically undergo pressure testing in two ways: either they are fixed in a fixture, or they are placed directly on a flat surface. Fixing the charging head in a fixture makes it highly susceptible to collision between the hydraulic pump head and the fixture during pressure testing. This can damage the testing equipment and consume significant time due to frequent adjustments to the fixture position and calibration of equipment parameters. Placing the charging head directly on a flat surface, lacking effective fixation, allows for displacement of the charging head during pressure application, resulting in uneven pressure distribution on critical parts of the charging head and thus deviations in test data. This necessitates repeated testing to obtain valid results. Both methods increase the complexity and uncertainty of the testing process, ultimately reducing testing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of fixing the charging gun in a way that reduces the testing efficiency. To address this, we propose a charging gun pressure withstand clamping test device.

[0007] Furthermore, the second clamping assembly includes a semi-circular clamping plate movably disposed on the surface of the movable plate. Two sets of semi-circular clamping plates are provided. A spacer plate is fixedly installed on one side of each set of semi-circular clamping plates. A spring B is fixedly installed at one end of the spacer plate. An anti-slip pad A is fixedly installed on the inner wall of the semi-circular clamping plate. An arc groove is fixedly installed at the upper end of the semi-circular clamping plate.

[0008] Furthermore, the third clamping assembly includes a right rectangular clamping plate and a left rectangular clamping plate movably disposed inside the movable plate. Anti-slip pads B are fixedly installed on one side of both the right and left rectangular clamping plates. The right and left rectangular clamping plates are located at the handle of the charging gun body. A rotating shaft is provided between the right and left rectangular clamping plates and is movably connected to the movable plate. A gear is fixedly installed on the outer surface of the rotating shaft. A base plate is fixedly installed on the lower surface of both the right and left rectangular clamping plates. A rack A is fixedly installed on one side of the base plate. There are two sets of racks A, which are symmetrically arranged and mesh with the gears.

[0009] The movable plate has a horizontal groove inside and a sliding groove on its surface. A rod groove is formed between the sliding groove and the horizontal groove. The bottom plate is slidably connected to one end of the horizontal groove.

[0010] Furthermore, the linkage component includes a rectangular block movably disposed inside the second clamping component. The rectangular block is movably connected to the semi-circular clamping plate. An arc plate is fixedly installed on the upper surface of the rectangular block. The lower surface of the arc plate is in contact with the inner wall of the semi-circular clamping plate. A long rod is provided on one side of the rectangular block. A movable frame is movably disposed inside the movable plate. A slanted groove is provided on one side of the movable frame. The slanted groove is slidably connected to the long rod. A spring C is fixedly installed on one side of the movable frame. A side plate is fixedly installed on the other side of the movable frame. Teeth are fixedly installed on both the side plate and one side of the movable frame. The teeth mesh with the gears. The side plate is located below the rack A.

[0011] The rectangular block is slidably connected to the slide groove, the rod groove is slidably connected to the long rod, one end of the spring C is fixedly connected to the inner wall of the other side of the horizontal groove, and the movable frame is slidably connected to the horizontal groove.

[0012] Furthermore, the workbench surface is provided with a bottom groove and a vertical groove. The vertical groove is slidably connected to the L plate, and the bottom groove is slidably connected to the first clamping plate and the second clamping assembly.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In this invention, the charging gun body is placed on the workbench surface. When pressed down, the charging gun body's front end is fixed inside the first clamping plate, while the rear end is locked inside two sets of semi-circular clamping plates. When the rear end of the charging gun body enters the two sets of semi-circular clamping plates, it contacts the arc plate and causes the rectangular block to descend. At this time, the long rod moves along the inclined groove, causing the movable frame to move to the left and compress the spring C. Subsequently, the side plate drives the gear to rotate through the teeth, thereby allowing the right rectangular clamping plate and the left rectangular clamping plate to clamp the charging gun handle. Then, the hydraulic pump drives the pressure plate to descend, and the pressure plate pushes the L plate to descend the movable plate. The clamping component gradually enters the rectangular groove, and finally the pressure plate presses completely against the charging gun body for pressure testing. After the test is completed, the pressure plate rises, and the clamping component resets to wait for the next set of charging guns to be tested. This improves the efficiency of charging gun body testing. Attached Figure Description

Charging gun body. Detailed Implementation

[0027] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a charging gun withstand pressure clamping test device, including a workbench 1, a charging gun body 5 is provided on the surface of the workbench 1, a clamping component 4 for fixing the charging gun body 5 is movably provided inside the workbench 1, and a hydraulic pump 3 is provided above the workbench 1.

[0029] The clamping component 4 includes a movable plate 41 movably disposed inside the workbench 1. A first clamping plate 414, a second clamping assembly 42 for further fixing the charging gun body 5, and a third clamping assembly 43 for improving the fixing effect are movably disposed on the surface of the movable plate 41. A linkage assembly 44 for driving the third clamping assembly 43 is movably disposed inside the second clamping assembly 42. The charging gun body 5 is located inside the first clamping plate 414, the second clamping assembly 42, and the third clamping assembly 43. A post hole 415 is opened on the surface of the movable plate 41. A limit post 411 is movably disposed inside the post hole 415. A spring A412 is disposed on the outer surface of the limit post 411. The end of the spring A412 is fixedly installed on the lower surface of the movable plate 41, and the other end of the spring A412 is fixedly installed inside the worktable 1. By fixing the charging gun body 5 with the first clamping plate 414, the second clamping component 42, and the third clamping component 43, the stability of the charging gun body 5 can be ensured when the charging gun body 5 detects the pressure value. It also improves the installation efficiency between the charging gun body 5 and the first clamping plate 414, the second clamping component 42, and the third clamping component 43, thereby improving the detection efficiency. Furthermore, by using the movable plate 41, which can be raised and lowered, the clamping component 4 can also be lowered when the hydraulic pump 3 descends, so that the hydraulic pump 3 can gradually and completely compact the charging gun body 5.

[0030] Reference Figures 1-9 As shown in this embodiment: the second clamping assembly 42 includes a semi-circular clamping plate 421 movably disposed on the surface of the movable plate 41. Two sets of semi-circular clamping plates 421 are provided. A spacer plate 422 is fixedly installed on one side of each set of semi-circular clamping plates 421. A spring B 423 is fixedly installed at one end of the spacer plate 422. An anti-slip pad A 424 is fixedly installed on the inner wall of the semi-circular clamping plate 421. An arc groove 425 is fixedly installed on the upper end of the semi-circular clamping plate 421. The spring B 423 allows the two sets of semi-circular clamping plates 421 to clamp the tail end of the charging gun body 5. The arc groove 425 allows the clamping component 4 to press and insert the charging gun body 5 into the clamping component 4 during installation. Finally, the anti-slip pad A 424 can increase the friction between the semi-circular clamping plate 421 and the charging gun body 5, thereby improving the stability between the second clamping assembly 42 and the charging gun body 5.

[0031] The third clamping assembly 43 includes a right rectangular clamping plate 431 and a left rectangular clamping plate 432 movably disposed inside the movable plate 41. Anti-slip pads B437 are fixedly installed on one side of both the right rectangular clamping plate 431 and the left rectangular clamping plate 432. The right rectangular clamping plate 431 and the left rectangular clamping plate 432 are located at the handle of the charging gun body 5. A rotating shaft 435 is provided between the right rectangular clamping plate 431 and the left rectangular clamping plate 432. The rotating shaft 435 is movably connected to the movable plate 41. A gear 436 is fixedly installed on the outer surface of the rotating shaft 435. A base plate 433 is fixedly installed on the lower surface of both the right rectangular clamping plate 431 and the left rectangular clamping plate 432. A rack A434 is fixedly installed on one side of the base plate 433. Two sets of racks A434 are provided. The two sets of racks A434 are symmetrically arranged and mesh with the gear 436.

[0032] The movable plate 41 has a transverse groove 416 inside and a sliding groove 417 on its surface. A rod groove 418 is formed between the sliding groove 417 and the transverse groove 416. The bottom plate 433 is slidably connected to one end of the transverse groove 416. The position of the handle of the charging gun body 5 is also fixed by the right rectangular clamping plate 431 and the left rectangular clamping plate 432, thereby improving the stability of the charging gun body 5. The rotation of the gear 436 allows the right rectangular clamping plate 431 and the left rectangular clamping plate 432 to move synchronously, thereby simultaneously fixing the handle of the charging gun body 5.

[0033] The linkage component 44 includes a rectangular block 441 movably disposed inside the second clamping component 42. The rectangular block 441 is movably connected to the semi-circular clamping plate 421. An arc plate 442 is fixedly installed on the upper surface of the rectangular block 441. The lower surface of the arc plate 442 is in contact with the inner wall of the semi-circular clamping plate 421. A long rod 443 is provided on one side of the rectangular block 441. A movable frame 444 is movably disposed inside the movable plate 41. A slanted groove 446 is provided on one side of the movable frame 444. The slanted groove 446 is slidably connected to the long rod 443. A spring C445 is fixedly installed on one side of the movable frame 444. A side plate 447 is fixedly installed on the other side of the movable frame 444. Teeth 448 are fixedly installed on both the side plate 447 and one side of the movable frame 444. Teeth 448 mesh with gears 436. The side plate 447 is located below the rack A434.

[0034] The rectangular block 441 is slidably connected to the slide groove 417, the rod groove 418 is slidably connected to the long rod 443, one end of the spring C445 is fixedly connected to the inner wall of the other side of the transverse groove 416, and the movable frame 444 is slidably connected to the transverse groove 416. When the charging gun body 5 is installed on the surface of the semi-circular clamping plate 421, the arc plate 442 will descend, thereby moving the long rod 443 along the inclined groove 446. Since the movable frame 444 can only move horizontally, the movable frame 444 will move to the left, thereby compressing the spring C445, causing the side plate 447 to drive the gear 436 to rotate through the teeth 448, thereby driving the right rectangular clamping plate 431 and the left rectangular clamping plate 432 to clamp and fix the handle of the charging gun body 5, thereby improving the stability of the charging gun body 5 after it is clamped.

[0035] The workbench 1 has a bottom groove 13 and a vertical groove 15 on its surface. The vertical groove 15 is slidably connected to the L-plate 413. The bottom groove 13 is slidably connected to the first clamping plate 414 and the second clamping assembly 42. The workbench 1 has a rectangular groove 14 inside. The rectangular groove 14 is slidably connected to the movable plate 41. The other end of the spring A412 is fixedly installed at the bottom of the rectangular groove 14. The lower surface of the limiting post 411 is fixedly installed at the bottom of the rectangular groove 14. When the hydraulic pump 3 is fully pressed against the charging gun body 5 through the rectangular groove 14, the clamping component 4 can enter the rectangular groove 14 to prevent the hydraulic pump 3 from damaging the clamping component 4. Then, through the vertical groove 15 and the L-plate 413, when the hydraulic pump 3 descends and contacts the L-plate 413, the hydraulic pump 3 will drive the movable plate 41 to descend through the L-plate 413.

[0036] A support column 11 is fixedly installed on the upper surface of the workbench 1, and a top plate 12 is fixedly installed on the upper surface of the support column 11. A storage slot 16 is opened inside the workbench 1, and a partition plate 422 is movably connected to the storage slot 16. The other end of the spring B423 is fixedly installed to the inner wall of the storage slot 16. A hydraulic pump 3 is fixedly installed on the surface of the top plate 12. A display screen 2 is fixedly installed on one side of the workbench 1. A hydraulic rod 31 is provided at the output end of the hydraulic pump 3, and a pressure plate 32 is fixedly installed at one end of the hydraulic rod 31. The pressure plate can be detected through the display screen 2. The pressure of the pressure plate 32 pressing against the charging gun body 5 will cause the pressure plate 32 to contact the L plate 413 when it descends, thus causing the L plate 413 to descend and allowing the clamping component 4 to gradually enter the rectangular groove 14. At this time, only the charging gun body 5 remains on the surface of the worktable 1. At this time, the hydraulic pump 3 will press the charging gun body 5 completely. When the pressure plate 32 rises, the clamping component 4 will extend again with the first clamping plate 414, the second clamping component 42, and the third clamping component 43 to clamp the next set of charging gun bodies 5.

[0037] Working principle: The charging gun body 5 is placed on the surface of the workbench 1. First, the charging gun body 5 is pressed down, with its head fixed inside the first clamping plate 414 and its tail end stuck between two sets of semi-circular clamping plates 421. When the tail end enters the semi-circular clamping plate 421, it will contact the arc plate 442 and drive the rectangular block 441 to descend. At the same time, the long rod 443 moves along the inclined groove 446, causing the movable frame 444 to move to the left and compress the spring C445. Then, the side plate 447 drives the gear 436 to rotate through the teeth 448, so that the right rectangular clamping plate 431 and the left rectangular clamping plate 432 clamp the charging gun handle, thus achieving a stable fixation of the charging gun body 5. Subsequently, the hydraulic pump 3 is started to drive... The pressure plate 32 descends, pushing the L plate 413 to lower the movable plate 41. The clamping component 4 gradually enters the rectangular groove 14, preventing the hydraulic pump 3 from colliding with the clamping component 4. As the pressure plate 32 continues to descend, it eventually presses completely against the charging gun body 5 for pressure testing. During the test, the display screen 2 shows the pressure value of the pressure plate 32 pressing against the charging gun body 5 in real time. After the test is completed, the hydraulic pump 3 drives the pressure plate 32 to rise, and the elastic force of the spring A412 causes the movable plate 41 to drive the clamping component 4 to reset. The first clamping plate 414, the second clamping component 42, and the third clamping component 43 return to their initial state, waiting for the placement and testing of the next set of charging guns. This improves the efficiency of the charging gun body 5 testing.
