Description

Technical Field

[0001] This utility model relates to the field of automotive fastener technology, and in particular to an automotive fastener pressure testing device. Background Technology

[0002] Automotive fasteners, as the name suggests, are a type of mechanical parts used for fastening and connecting automobiles. In order to ensure the safety of automotive fasteners during use, pressure testing is required on the corresponding automotive fasteners, so appropriate pressure testing equipment is needed.

[0003] Chinese patent CN218121372U discloses an automotive fastener pressure testing device, including an automotive fastener pressure testing base, a U-shaped pressure testing support frame, a control box, an automotive fastener placement platform, an automotive fastener pressure testing machine, and an automotive fastener pressure testing machine fixing column. The upper surface of the automotive fastener pressure testing base is fixedly connected to the two sides of the bottom surface of the U-shaped pressure testing support frame via bolts. The control box is bolted to the middle of one side of the U-shaped pressure testing support frame. This invention allows for the simultaneous placement of two automotive fasteners for pressure testing. Once one fastener is tested, the other can be tested immediately. During the testing of the other fastener, the first fastener can be removed, and a new one can be placed in. This effectively reduces the time required for exchanging two fasteners, making it more efficient and convenient, and facilitating market promotion and application.

[0004] However, the above-mentioned solution, when testing automotive fasteners, places the fasteners on the automotive fastener fixture without securing them, which can cause the bolt to shift or rotate during the test. This makes it impossible to accurately measure the actual pressure on the bolt. Furthermore, the presence of multiple threaded holes on the connecting plate may weaken the overall strength of the connecting plate, especially when the distance between the threaded holes is small. This may affect the stability and reliability of the testing machine under high loads. Therefore, an automotive fastener pressure testing device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the existing technical problems of placing automotive fasteners on fastener fixtures during testing, which can cause bolt displacement or rotation during testing, making it impossible to accurately measure the actual pressure on the bolts, and the fact that multiple threaded holes on the connecting plate weaken the overall strength of the connecting plate and affect the stability of the testing machine under high loads, this invention proposes an automotive fastener pressure testing device.

[0006] This utility model proposes an automotive fastener pressure testing device, which includes a frame. A switching device is provided on the outer surface of the frame. The switching device includes a rotating block, and the rotation of the rotating block switches the automotive fastener.

[0007] The outer surface of the frame is provided with a testing device, which includes an arc-shaped clamp. The extension and retraction of the arc-shaped clamp secures the automotive fasteners.

[0008] Preferably, the switching device includes a drive motor, which is fixedly mounted on the outer surface of the frame. A rotating rod is fixedly mounted on the output shaft of the drive motor via a coupling. A drive gear is fixedly mounted on the outer surface of the rotating rod. A support rod is rotatably connected to the inner wall of the rotating rod, and the support rod is fixedly mounted on the outer surface of the frame.

[0009] The above technical solution involves installing a drive motor to drive a rotating rod to rotate, which in turn drives a drive gear to rotate. A support rod is connected to the rotating rod, and the rotation of the rotating rod does not affect the support rod. The drive gear meshes with the rotating gear, causing the rotating gear to rotate, which in turn drives the rotating rod, which is fixedly installed with the rotating gear, to rotate. This causes the rotating block, which is fixedly installed with the rotating rod, to rotate. The rotating block is slidably inserted into the rotating frame, thereby causing the rotating frame to rotate, so as to switch automotive fasteners.

[0010] Preferably, a rotating frame is rotatably connected to the outer surface of the support rod, and a rotating rod is fixedly installed on the outer surface of the frame via a bearing. The outer surface of the rotating rod is fixedly installed to the outer surface of the rotating block, and one end of the rotating block is slidably inserted into the inner wall of the groove of the rotating frame.

[0011] The above technical solution involves a rotating frame connected to the outer surface of a support rod, which supports the rotating frame without affecting its rotation. A rotating rod is fixedly installed using bearings, which fixes the rotating rod without affecting the frame's rotation. The rotating rod is fixedly installed to a rotating block, and the rotation of the rotating rod drives the rotating block to rotate. One side of the rotating block is an L-shaped support rod, the outer surface of which slides into the rotating frame, causing the rotating frame to rotate. The other side of the rotating block is a fan-shaped plate, which contacts the rotating frame and limits its movement, allowing for the switching of automotive fasteners.

[0012] Preferably, a rotating gear is fixedly installed on the outer surface of the rotating rod, the rotating gear meshes with the driving gear, and a sleeve is fixedly installed on the outer surface of the rotating frame through a support plate, and a conical sleeve is fixedly installed on the inner bottom wall of the sleeve.

[0013] The above technical solution involves a rotating gear meshing with a drive gear to rotate the drive gear. A sleeve is fixedly installed on the outer surface of the rotating frame via a support plate for support. A conical sleeve is fixedly installed on the inner wall of the sleeve. The sleeve is threadedly connected to a lifting gear. The inner wall of the groove of the lifting gear rotates and engages with the outer surface of the conical sleeve to fix the automotive fasteners placed in the conical sleeve.

[0014] Preferably, the inner wall of the sleeve is threadedly connected to a lifting gear, the inner wall of the threaded sleeve of the lifting gear is rotatably sleeved with the outer surface of the conical sleeve, a rotary motor is fixedly installed on the outer surface of the frame, and a rotating gear is fixedly installed on the output shaft of the rotary motor, the rotating gear meshing with the lifting gear.

[0015] The above technical solution involves connecting a lifting gear to the inner wall of the sleeve via a threaded connection, providing support. A rotary motor drives the rotating gear to rotate, which in turn drives the lifting gear meshing with the rotating gear to rotate. This causes the threaded sleeve to descend within the sleeve, thereby tightening the rotating conical sleeve and securing the automotive fasteners placed inside the conical sleeve.

[0016] Preferably, the testing device further includes a testing platform, which is fixedly installed on the outer surface of the frame. A testing housing is slidably inserted into the outer surface of the testing platform via a sliding rod. A lifting hydraulic cylinder is fixedly installed on the outer surface of the frame, and the outer surface of the telescopic rod of the lifting hydraulic cylinder is fixedly installed with the outer surface of the testing housing.

[0017] The above technical solution facilitates pressure testing of automotive fasteners by installing a test bench. The test housing is slidably inserted into the outer surface of the test bench via a slide rod, supporting the test housing without affecting its lifting. The outer surface of the telescopic rod of the lifting hydraulic cylinder is fixedly installed to the test housing. The extension and retraction of the telescopic rod of the lifting hydraulic cylinder drives the test housing to rise and fall, so as to perform pressure testing on the automotive fasteners.

[0018] Preferably, a fixed hydraulic cylinder is fixedly installed on the outer surface of the test housing, and a fixed block is fixedly installed on the outer surface of the telescopic rod of the fixed hydraulic cylinder, and the outer surface of the fixed block is slidably inserted into the outer surface of the arc-shaped clamp.

[0019] The above technical solution involves fixing the outer surface of the telescopic rod of the fixed hydraulic cylinder to the fixed block. The telescopic rod of the fixed hydraulic cylinder extends and retracts, causing the fixed block to move. The fixed block is slidably inserted into the arc-shaped clamp, which consists of a rotating ring and a fixed clamp. The rotating ring is slidably inserted into the fixed block, and the outer surface of the rotating ring is slidably inserted into the fixed clamp. This facilitates automatic adjustment of the orientation when fixing irregularly shaped parts, enabling pressure testing of automotive fasteners of different specifications.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. By setting up a switching device, the automotive fastener is switched. The drive motor drives the rotating rod to rotate, which in turn drives the drive gear to rotate, which in turn drives the rotating gear meshing with it to rotate. This causes the rotating rod, which is fixedly installed with the rotating gear, to rotate, which in turn drives the rotating block to rotate. The rotating block is slidably inserted into the rotating frame. One side of the rotating block is an L-shaped support rod, the outer surface of which is slidably inserted into the rotating frame, driving the rotating frame to rotate. The other side of the rotating block is a sector plate, which contacts the rotating frame and limits its movement, so as to switch the automotive fastener. The rotating motor drives the rotating gear to rotate, which in turn drives the lifting gear meshing with the rotating gear to rotate, causing the threaded sleeve to descend inside the sleeve, tightening the conical sleeve that is rotated, so as to fix the automotive fastener placed in the conical sleeve. This solves the technical problem that when testing automotive fasteners, if the automotive fasteners are placed on the automotive fastener fixture without being fixed, the entire bolt will be displaced or rotated during the test, and the test cannot accurately measure the actual pressure on the bolt.

[0022] 2. By setting up a testing device, automotive fasteners are fixed, and a testing bench performs pressure tests on them. The outer surface of the telescopic rod of the lifting hydraulic cylinder is fixedly installed to the testing machine housing. The telescopic rod of the lifting hydraulic cylinder extends and retracts, causing the testing machine housing to rise and fall on a slidingly connected slide rod to perform pressure tests on the automotive fasteners. The outer surface of the telescopic rod of the fixing hydraulic cylinder is fixedly installed to a fixing block. The telescopic rod of the fixing hydraulic cylinder extends and retracts, causing the fixing block to move. The fixing block slides into an arc-shaped clamp, which consists of a rotating ring and a fixing clamp. The rotating ring slides into the fixing block, and the outer surface of the rotating ring slides into the fixing clamp. This facilitates automatic adjustment of the orientation when fixing irregularly shaped parts, enabling pressure testing of automotive fasteners of different specifications. This solves the technical problem that when testing automotive fasteners, opening multiple threaded holes on the connecting plate may weaken the overall strength of the connecting plate, especially when the distance between the threaded holes is small, which may affect the stability and reliability of the testing machine under high loads.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figures 1-5 An automotive fastener pressure testing device includes a frame 1, and a switching device is provided on the outer surface of the frame 1. The switching device includes a rotating block 32, and the rotation of the rotating block 32 switches the automotive fastener.

[0031] To drive the rotating gear 4 to rotate, the switching device includes a drive motor 2, which is fixedly mounted on the outer surface of the frame 1. The output shaft of the drive motor 2 is fixedly mounted with a rotating rod 21 via a coupling. A drive gear 22 is fixedly mounted on the outer surface of the rotating rod 21. A support rod 23 is rotatably connected to the inner wall of the rotating rod 21. The support rod 23 is fixedly mounted on the outer surface of the frame 1. By installing the drive motor 2, the rotating rod 21 is driven to rotate, which in turn drives the drive gear 22 to rotate. The rotation of the rotating rod 21 does not affect the support rod 23. The drive gear 22 meshes with the rotating gear 4, driving the rotating gear 4 to rotate, which in turn drives the rotating rod 31, which is fixedly mounted with the rotating gear 4, to rotate. This drives the rotating block 32, which is fixedly mounted with the rotating rod 31, to rotate. The rotating block 32 is slidably inserted into the rotating frame 3, thereby driving the rotating frame 3 to rotate, so as to switch the automotive fasteners.

[0032] To drive the rotating block 32 to rotate, a rotating frame 3 is rotatably connected to the outer surface of the support rod 23. A rotating rod 31 is fixedly installed on the outer surface of the frame 1 via bearings. The outer surface of the rotating rod 31 is fixedly installed on the outer surface of the rotating block 32. One end of the rotating block 32 is slidably inserted into the inner wall of the groove of the rotating frame 3. The rotating frame 3 is rotatably connected to the outer surface of the support rod 23, which supports the rotating frame 3 without affecting its rotation. The rotating rod 31 is fixedly installed via bearings, which fixes the rotating rod 31 without affecting the frame 1. The rotating rod 31 is fixedly installed with the rotating block 32. The rotation of the rotating rod 31 drives the rotating block 32 to rotate. One side of the rotating block 32 is an L-shaped support rod. The outer surface of the support rod is slidably inserted into the rotating frame 3, which drives the rotating frame 3 to rotate. The other side of the rotating block 32 is a fan-shaped plate. The fan-shaped plate contacts the rotating frame 3 and limits its movement so as to switch the automotive fasteners.

[0033] To drive the drive gear 22 to rotate, a rotating gear 4 is fixedly installed on the outer surface of the rotating rod 31. The rotating gear 4 meshes with the drive gear 22. A sleeve 41 is fixedly installed on the outer surface of the rotating frame 3 via a support plate. A conical sleeve 42 is fixedly installed on the inner bottom wall of the sleeve 41. The rotating gear 4 meshes with the drive gear 22, driving the drive gear 22 to rotate. The sleeve 41 is fixedly installed on the outer surface of the rotating frame 3 via a support plate for fixed support. The conical sleeve 42 is fixedly installed on the inner wall of the sleeve 41. The sleeve 41 is threadedly connected to the lifting gear 5. The inner wall of the groove of the lifting gear 5 is rotatably sleeved with the outer surface of the conical sleeve 42 to fix the automotive fasteners placed in the conical sleeve 42.

[0034] To drive the rotating gear 52 to rotate, the inner wall of the sleeve 41 is threadedly connected to the lifting gear 5. The inner wall of the threaded sleeve of the lifting gear 5 is rotatably sleeved with the outer surface of the conical sleeve 42. A rotary motor 51 is fixedly installed on the outer surface of the frame 1. The output shaft of the rotary motor 51 is fixedly installed with the rotating gear 52. The rotating gear 52 meshes with the lifting gear 5. The lifting gear 5 is threadedly connected to the inner wall of the sleeve 41 through the threaded sleeve to support it. The rotary motor 51 drives the rotating gear 52 to rotate, thereby driving the lifting gear 5, which meshes with the rotating gear 52, to rotate. This causes the threaded sleeve to descend inside the sleeve 41, thereby tightening the rotatably sleeved conical sleeve 42 to fix the automotive fasteners placed in the conical sleeve 42.

[0035] By setting up a switching device, the automotive fasteners are switched. The drive motor 2 drives the rotating rod 21 to rotate, which in turn drives the drive gear 22 to rotate, which in turn drives the rotating gear 4 meshing with it to rotate. This causes the rotating rod 31, which is fixedly installed with the rotating gear 4, to rotate, which in turn drives the rotating block 32 to rotate. The rotating block 32 is slidably inserted into the rotating frame 3. One side of the rotating block 32 is an L-shaped support rod, the outer surface of which is slidably inserted into the rotating frame 3, causing the rotating frame 3 to rotate. The other side of the rotating block 32 is a fan-shaped plate, which contacts the rotating frame 3 and limits its movement to facilitate the switching of the automotive fasteners. The switching process involves the rotary motor 51 driving the rotary gear 52 to rotate, which in turn drives the lifting gear 5 meshing with the rotary gear 52 to rotate. This causes the threaded sleeve to descend within the sleeve 41, tightening the rotating conical sleeve 42 to secure the automotive fastener placed inside the conical sleeve 42. This solves the technical problem that when testing automotive fasteners, placing the fasteners on the automotive fastener fixture without securing them causes the bolt to shift or rotate during the test, making it impossible to accurately measure the actual pressure exerted on the bolt.

[0036] In order to secure the automotive fasteners, a testing device is provided on the outer surface of the frame 1. The testing device includes an arc-shaped clamp 72, which secures the automotive fasteners by extending and retracting.

[0037] To facilitate the lifting and lowering of the test housing 61, the testing device also includes a test bench 6, which is fixedly installed on the outer surface of the frame 1. The test housing 61 is slidably inserted into the outer surface of the test bench 6 via a slide rod. A lifting hydraulic cylinder 62 is fixedly installed on the outer surface of the frame 1. The outer surface of the telescopic rod of the lifting hydraulic cylinder 62 is fixedly installed with the outer surface of the test housing 61. By installing the test bench 6, it is convenient to perform pressure testing on automotive fasteners. The test housing 61 is slidably inserted into the outer surface of the test bench 6 via a slide rod, which supports the test housing 61 without affecting its lifting and lowering. The outer surface of the telescopic rod of the lifting hydraulic cylinder 62 is fixedly installed with the test housing 61. The extension and retraction of the telescopic rod of the lifting hydraulic cylinder 62 drives the test housing 61 to lift and lower, so as to perform pressure testing on automotive fasteners.

[0038] To move the fixed block 71, a fixed hydraulic cylinder 7 is fixedly installed on the outer surface of the test housing 61. The fixed block 71 is fixedly installed on the outer surface of the telescopic rod of the fixed hydraulic cylinder 7. The outer surface of the fixed block 71 is slidably inserted into the outer surface of the arc-shaped clamp 72. The fixed block 71 is fixedly installed on the outer surface of the telescopic rod of the fixed hydraulic cylinder 7. The telescopic rod of the fixed hydraulic cylinder 7 extends and retracts, causing the fixed block 71 to move. The fixed block 71 is slidably inserted into the arc-shaped clamp 72. The arc-shaped clamp 72 consists of a rotating ring and a fixed clamp. The rotating ring is slidably inserted into the fixed block 71. The outer surface of the rotating ring is slidably inserted into the fixed clamp. This facilitates automatic adjustment of the orientation when fixing irregularly shaped parts, so as to perform pressure testing on automotive fasteners of different specifications.

[0039] By setting up a testing device, automotive fasteners are fixed, and the testing bench 6 performs pressure tests on the automotive fasteners. The outer surface of the telescopic rod of the lifting hydraulic cylinder 62 is fixedly installed with the testing machine housing 61. The telescopic rod of the lifting hydraulic cylinder 62 extends and retracts, causing the testing machine housing 61 to rise and fall on the slidingly inserted slide rod, so as to perform pressure tests on the automotive fasteners. The outer surface of the telescopic rod of the fixing hydraulic cylinder 7 is fixedly installed with the fixing block 71. The telescopic rod of the fixing hydraulic cylinder 7 extends and retracts, causing the fixing block 71 to move. The fixing block 71 is slidably inserted with the arc-shaped clamp 72. The arc-shaped clamp 72 consists of a rotating ring and a fixing clamp. The rotating ring is slidably inserted with the fixing block 71, and the outer surface of the rotating ring is slidably inserted with the fixing clamp. This facilitates automatic adjustment of the orientation when fixing irregularly shaped parts, so as to perform pressure tests on automotive fasteners of different specifications. This solves the technical problem that when testing automotive fasteners, opening multiple threaded holes on the connecting plate may weaken the overall strength of the connecting plate, especially when the distance between the threaded holes is small, which may affect the stability and reliability of the testing machine under high load.

[0040] Working principle: When it is necessary to switch the car fasteners, the drive motor 2 is started to drive the drive gear 22 on the rotating rod 21 to rotate. The drive gear 22 meshes with the rotating gear 4, which drives the rotating rod 31 fixed thereto to rotate, thereby driving the rotating block 32 fixedly installed with the rotating rod 31 to rotate. One side of the rotating block 32 is a fan-shaped plate, which contacts the rotating frame 3 and limits its movement. The other side of the rotating block 32 is an L-shaped support rod, the outer surface of which slides into the rotating frame 3, driving the rotating frame 3 to rotate. At the same time, the rotating motor 51 is started to drive the rotating gear 52 to rotate, which drives the lifting gear 5 meshing with the rotating gear 52 to rotate, causing the threaded sleeve in the sleeve 41 to descend, thereby tightening the rotating sleeve 42 and fixing the car fastener placed in the conical sleeve 42.

[0041] When testing the fixed automotive fasteners, as the fasteners fixed by the conical sleeve 42 turn towards the test bench 6, the lifting hydraulic cylinder 62 is activated. The extension rod of the lifting hydraulic cylinder 62 extends, causing the fixed test housing 61 to descend on the slidingly inserted slide rod. When it descends to the designated position, the fixing hydraulic cylinder 7 is activated. The extension rod of the fixing hydraulic cylinder 7 extends, causing the two fixing blocks 71 to move relative to each other, thereby causing the slidingly inserted arc-shaped clamp 72 to move relative to each other. The arc-shaped clamp 72 consists of a rotating ring and a fixing clamp. The rotating ring slides into the fixing block 71, and the outer surface of the rotating ring slides into the fixing clamp, which facilitates automatic adjustment of the orientation when fixing irregularly shaped parts, so as to perform pressure testing on automotive fasteners of different specifications.
