Description

Technical Field

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

[0002] A car wheel hub, also known as a rim, steel rim, or wheel, is a cylindrical metal component inside a car tire that supports the tire around its axle. Located at the center of the wheel, where the axle is mounted, it is a crucial component connecting the brake drum (brake disc), wheel disc, and half-shaft. After production, car wheel hubs undergo strength testing to ensure quality.

[0003] Most existing automotive wheel hub strength tests first fix the wheel hub on a platform, apply pressure to the wheel hub with an extrusion head, and then perform strength analysis using a testing instrument. When testing other parts of the wheel hub surface, since the extrusion head is fixed, the wheel hub needs to be loosened and its position adjusted before testing other parts of the wheel hub. This is quite troublesome and wastes time. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vehicle wheel hub strength testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vehicle wheel hub strength testing device includes a support frame, a fixed frame fixedly connected to the top of the support frame, a sliding rod connected to a slide plate inside the fixed frame, second sliding grooves on both sides of the slide plate, a slider on the outer side of the slide plate to move along the grooves of the second sliding grooves, a pressing head fixedly connected to the bottom of the slider, an insertion assembly for fixing the slider on one side of the slider, and a camera for capturing images of the wheel hub pressing area fixedly connected to the other side of the slider. A hydraulic cylinder is fixedly connected to the top of the fixed frame, and one end of the hydraulic rod of the hydraulic cylinder passes through the fixed frame and is fixed to the slide plate. A turntable is rotatably connected to the upper surface of the support frame located inside the fixed frame. A clamping assembly for fixing the wheel hub is provided on the upper surface of the turntable, and a locking assembly for fixing the turntable is provided on the upper surface of the support frame.

[0007] As a further embodiment of this utility model, the insertion assembly includes a sliding sleeve, which is fixedly connected to the side of the slider away from the camera. A round rod is provided inside the sliding sleeve, and both ends of the round rod pass through the sliding sleeve. A round plate is fixedly connected to the outer side of the round rod inside the sliding sleeve. A plurality of second insertion ports are provided on the side of the sliding plate near the sliding sleeve, and the round rod passes through the slider and is inserted into the second insertion ports.

[0008] As a further embodiment of this utility model, a second spring is sleeved on the outer side of the round rod, and the two ends of the second spring are fixed to the round plate and the sliding sleeve, respectively.

[0009] As a further embodiment of this utility model, the locking assembly includes a guide frame, which is fixedly connected to the top of the support frame. A plug is slidably connected inside the guide frame. The outer circumferential wall of the turntable has multiple evenly distributed first sockets, and the plug is inserted into the first sockets.

[0010] As a further embodiment of this utility model, two first springs are sleeved on the outer side of the guide frame, and the two ends of the first springs are fixed to the insert and the guide frame respectively.

[0011] As a further embodiment of this utility model, the clamping assembly includes two first sliding grooves, both of which are opened on the top of the turntable.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, by using the slider and the turntable together, the slider is moved along the second groove on the slide plate, thereby changing the position of the extrusion head. At the same time, the turntable is rotated to adjust the position of the wheel hub being detected, which facilitates the detection of other positions of the wheel hub, saves time and improves detection efficiency.

[0015] 2. In this utility model, by using the interlocking assembly and the locking assembly together, after the positions of the extrusion head and the hub are adjusted, the position of the slider is fixed by the interlocking assembly, and then the turntable is fixed by the locking assembly.

[0020] 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. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0021] Reference Figures 1-3 A vehicle wheel hub strength testing device includes a support frame 1, a fixing frame 3 bolted to the top of the support frame 1, a sliding rod connected to a slide plate 2 inside the fixing frame 3, second sliding grooves 21 on both sides of the slide plate 2, a slider 18 on the outer side of the slide plate 2, allowing the slider 18 to move along the grooves of the second sliding grooves 21, a pressing head 19 bolted to the bottom of the slider 18, an insertion assembly for fixing the slider 18 on one side, and a camera 20 for capturing images of the wheel hub pressing area bolted to the other side of the slider 18, a hydraulic cylinder 4 bolted to the top of the fixing frame 3, with one end of the hydraulic rod of the hydraulic cylinder 4 passing through the fixing frame 3 and fixed to the slide plate 2, and a turntable 5 rotatably connected to the upper surface of the support frame 1 located inside the fixing frame 3. The upper surface of the turntable 5 is provided with a clamping assembly for fixing the wheel hub, and the upper surface of the support frame 1 is provided with a locking assembly for fixing the turntable 5. The wheel hub is clamped and fixed by the clamping assembly. The hydraulic cylinder 4 extends and pushes the slide plate 2 downward, so that the extrusion head 19 extrudes the wheel hub. During extrusion, the extrusion point of the wheel hub can be photographed by the camera 20, and the photographed photos can be sent to the back-end for staff to align and analyze the data to determine the strength of the wheel hub. When it is necessary to inspect other parts of the wheel hub, the slider 18 moves along the second slide groove 21 and the turntable 5 is rotated, thereby changing the position of the extrusion head 19 and the position of the wheel hub being inspected, which facilitates the inspection of other parts of the wheel hub, saves time, and improves inspection efficiency.

[0022] In this invention, the insertion assembly includes a sliding sleeve 17, which is bolted to the side of the slider 18 away from the camera 20. A round rod 16 is provided inside the sliding sleeve 17, with both ends of the rod 16 passing through it. A circular plate is welded to the outer side of the rod 16 inside the sliding sleeve 17. Multiple second insertion ports 14 are provided on the side of the slide plate 2 near the sliding sleeve 17, and the round rod 16 passes through the slider 18 and inserts into the second insertion ports 14. A second spring 15 is sleeved on the outer side of the round rod 16, with both ends of the second spring 15 fixed to the circular plate and the sliding sleeve 17 respectively. When it is necessary to insert the slider 18... When moving, the round rod 16 is pulled to move, and the round rod 16 will drive the round plate to move and squeeze the second spring 15. At this time, the round rod 16 will disengage from the second socket 14. Then the slider 18 can be pulled to move along the second slide groove 21. The slider 18 will drive the extrusion head 19 to move. When the extrusion head 19 moves to the appropriate position, the round rod 16 is released. The round rod 16 will be reset by the force of the second spring 15 and inserted into the corresponding second socket 14 to fix the position of the extrusion head 19, which can prevent the extrusion head 19 from moving when extruding the hub.

[0023] Specifically, the locking assembly includes a guide frame 13, which is bolted to the top of the support frame 1. A insert 12 is slidably connected inside the guide frame 13. The outer circumference of the turntable 5 has multiple evenly distributed first insertion slots 10, with the insert 12 engaging with each slot. Two first springs 11 are sleeved on the outer side of the guide frame 13, with both ends of the first springs 11 fixed to the insert 12 and the guide frame 13, respectively. When the turntable 5 needs to be rotated, the insert 12 is pulled to move it, causing it to compress the first springs 11 and disengage from the first insertion slots 10. At this point, the turntable 5 can be rotated, causing the clamped wheel hub to rotate, thus changing the wheel hub detection position. Then, the insert 12 is released, and the insert 12, under the force of the first springs 11, inserts into the corresponding first insertion slot 10 to detect the wheel hub. To prevent the turntable 5 from rotating during testing, the clamping assembly includes two first sliding grooves 9, both located on the top of the turntable 5. Each first sliding groove 9 has a clamping block 7 slidably connected within it. The turntable 5 has a rotating hole communicating with the two first sliding grooves 9. A bidirectional lead screw 8, extending into the first sliding groove 9, is rotatably connected within the rotating hole. The bidirectional lead screw 8 passes through the clamping block 7 and is threadedly connected to it. The two first sliding grooves 9 are symmetrically distributed on the top of the turntable 5. Both ends of the bidirectional lead screw 8 pass through the turntable 5 and are fixed with knobs by bolts. When clamping the wheel hub, the wheel hub is placed on the turntable 5, and then the bidirectional lead screw 8 is rotated. The bidirectional lead screw 8, through threaded engagement with the two clamping blocks 7, causes the two clamping blocks 7 to move towards each other within the first sliding grooves 9, thereby clamping the wheel hub.

[0024] Working principle: In use, the wheel hub is placed on the turntable 5, and then the double-acting screw 8 is rotated. The double-acting screw 8, through threaded engagement with the two clamping blocks 7, drives the two clamping blocks 7 to move towards each other in the first slide groove 9, thereby clamping the wheel hub. After clamping, the hydraulic cylinder 4 extends and pushes the slide plate 2 downward, thereby causing the extrusion head 19 to extrude the wheel hub. During extrusion, the extrusion point of the wheel hub can be photographed by the camera 20, and the photographed photos are sent to the back-end for staff to align and analyze the data to strengthen the wheel hub. When it is necessary to test other parts of the wheel hub, the round rod 16 is pulled to move. The round rod 16 will drive the round plate to move and extrude the second spring 15. At this time, the round rod 16 will disengage from the second insertion port 14, and then the slider 18 can be pulled. Moving along the second slide groove 21, the slider 18 will drive the extrusion head 19 to move. When the extrusion head 19 moves to the appropriate position, the round rod 16 is released. The round rod 16 will be reset by the force of the second spring 15 and inserted into the corresponding second socket 14 to fix the position of the extrusion head 19. Then, the insert 12 is pulled to move. The insert 12 will squeeze the first spring 11 and disengage from the first socket 10. At this time, the turntable 5 can be rotated. The turntable 5 will drive the clamped wheel hub to rotate, thereby changing the position of the wheel hub detection. Then, the insert 12 is released. The insert 12 will be inserted into the corresponding first socket 10 by the force of the first spring 11 to fix the position of the wheel hub to be detected, thereby facilitating the detection of other positions of the wheel hub, saving time and improving detection efficiency.
