Description

Technical Field

[0001] The utility model relates to the technical field of vehicle detection, in particular to a vehicle detection device which is convenient to adjust. Background Technique

[0002] As the core tool of modern transportation, the structure of an automobile is complex and its functions are diverse. It mainly consists of a body, an engine, a chassis and electrical equipment. The engine provides power for the automobile. The chassis bears the body and the engine and includes transmission, running, steering and braking systems. The wheel hub is one of the key components of an automobile. It bears the weight of the body and fixes the tire. Once there are defects or damages in the wheel hub, problems such as tire detachment and air leakage may occur, and in severe cases, it will endanger the lives of drivers and passengers. Therefore, in order to ensure driving safety, a vehicle detection device is used to detect the pressure of the vehicle wheel hub.

[0003] A Chinese patent with the publication number of CN210037458U discloses a detection device for vehicle wheel hub processing, including a base. The outer wall of the top of the base is fixed with a static clamp block by screws, and the same gantry is fixed on both sides of the outer wall of the top of the base by screws. An electric push rod is fixed on the inner wall of one side of the gantry by screws, and one end of the piston rod of the electric push rod is fixed with a moving clamp block by screws. A motor is fixed on the outer wall of one side of the gantry by screws, and the output shaft of the motor is connected with a lead screw through a coupling. A sliding plate is sleeved on the outer wall of the lead screw, and a hydraulic cylinder is fixed on the outer wall of the bottom of the sliding plate by screws. One end of the piston rod of the hydraulic cylinder is fixed with a pressing plate by screws, and an installation hole is opened on the outer wall of the bottom of the pressing plate. A pressure sensor is inserted into the inner wall of the installation hole.

[0004] Although the above scheme can detect the size while detecting the pressure and has powerful functions, the time for disassembly and assembly after the detection of the device cannot be detected synchronously, resulting in the influence on the detection efficiency. At the same time, it is not convenient to disassemble, assemble and adjust the wheel hub, and it is not convenient to use. Therefore, it does not meet the existing requirements. For this reason, we propose a vehicle detection device which is convenient to adjust. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a vehicle detection device which is convenient to adjust, including a base, a hydraulic cylinder is installed at the upper end of the base, and a pressure gauge is installed at the output end of the hydraulic cylinder;

[0007] It further includes a second transmission cavity which is opened inside the base. A rotating shaft is rotatably arranged in the second transmission cavity. One end of the rotating shaft extends to the outside of the second transmission cavity. A transmission worm gear is arranged on the outer wall of one end of the rotating shaft located inside the second transmission cavity.

[0008] It further includes a clamping seat which is arranged at one end of the rotating shaft outside the second transmission cavity.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By arranging a clamping seat above the base in the present utility model, when fixing the wheel hub of an automobile, the operator only needs to place the wheel hub on the front side of the clamping seat and rotate the knob to make the double-threaded transmission rod rotate.

[0017] 2. The utility model fixes the wheel hubs by arranging a second transmission cavity inside the base, enabling two wheel hubs to be fixed at one time. When the hydraulic cylinder is started to move the pressure gauge downward, the pressure of the wheel hubs clamped and fixed at the rear end of the clamping seat can be detected. After the detection is completed, only by starting the motor can the driving worm drive the driving worm gear to rotate, so that the rotating shaft can drive the clamping seat to rotate, and the detected wheel hubs can be rotated to the front side. The next wheel hub to be measured replaced by the operator will rotate to the rear side, enabling the next detection to be carried out quickly. The operator can replace the wheel hubs during the detection to achieve disassembly, replacement, and detection simultaneously, improving the detection efficiency.

[0029] During use, place the wheel hub on the base 1, rotate the knob 10 to drive the rotating rod 9 and the double-threaded transmission rod 8 to rotate, and then drive the two moving blocks 12 to move horizontally towards or away from each other under the guidance of the guide groove 11. The moving blocks 12 drive the arc-shaped clamping blocks 13 to clamp the wheel hub, realizing quick fixation. Start the motor 15, and through the worm drive of the transmission worm 16 and the transmission worm gear 17, the rotating shaft 18 and the clamping seat 6 are rotated 180 degrees, turning the wheel hub to the rear side. At this time, the hydraulic cylinder 2 drives the pressure gauge 3 to move downward for pressure detection. During the detection process, the operator can continue to fix the next wheel hub on the base 1 and quickly clamp it through the knob 10. After the detection is completed, the motor drives the clamping seat 6 to rotate 180 degrees again, facilitating the operator to quickly replace and detect, and at the same time realizing the synchronous progress of detection and disassembly and assembly, greatly improving the detection efficiency.

[0030] Please refer to Figure 3 and Figure 4 , a transmission worm 16 is provided on one side of the transmission worm gear 17, and there is a worm drive between the transmission worm 16 and the transmission worm gear 17. The worm drive can provide a large transmission ratio and a self-locking function, ensuring stable and reliable transmission during the transmission process, and at the same time reducing transmission errors caused by vibration or misoperation;

[0031] Please refer to Figure 3 and Figure 4 , a motor 15 is provided at the rear side inside the second transmission cavity 14, and the output end of the motor 15 is in transmission connection with the transmission worm 16 through a coupling. The motor 15 serves as a power source and is directly connected to the transmission worm 16 through the coupling, with high transmission efficiency. It can accurately control the rotation angle and speed of the transmission worm gear 17, providing stable power support for the rotation of the wheel hub;

[0032] Please refer to Figure 5 , guide grooves 11 are provided on both sides inside the first transmission cavity 7, and the guide grooves 11 are all in sliding fit with the moving blocks 12. The guide grooves 11 can ensure the stable movement of the moving blocks 12 in the horizontal direction, prevent them from shifting or shaking during rotation, and ensure the accuracy and reliability of the clamping of the wheel hub;

[0033] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , arc-shaped clamping blocks 13 are adhesively fixed to one ends of the moving blocks 12 located outside the second transmission cavity 14. The arc-shaped clamping blocks 13 can fit the curved surface of the wheel hub, and the clamping and fixing of the wheel hub are realized through the movement of the moving blocks 12. The clamping force is strong and the adaptability is good, which is suitable for wheel hubs of different sizes and shapes;

[0034] Please refer to Figure 1 , Figure 2 and Figure 5 , one end of the double-threaded transmission rod 8 is fixed with a rotating rod 9. One end of the rotating rod 9 extends to the outside of the second transmission cavity 14, and the rotating rod 9 is all in rotational fit with the second transmission cavity 14. Knobs 10 are arranged at one ends of the rotating rod 9 located outside the second transmission cavity 14.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 , a support 4 is arranged at the upper end of the base 1, and a transparent protective plate 5 is arranged at the upper end of the support 4. The transparent protective plate 5 can effectively prevent accidents caused by operation errors or failures during the detection process and ensure the safety of the operators.

[0036] Working principle: When in use, place the wheel hub at the front side inside the upper end of the base 1. Rotate the knob 10, which will drive the rotating rod 9 to rotate. The rotating rod 9 will drive the double-threaded transmission rod 8 to rotate. The double-threaded transmission rod 8 will drive the two moving blocks 12 to rotate synchronously. Since the moving blocks 12 are all in sliding fit with the guiding grooves 11, the moving blocks 12 will all be axially limited. The rotation of the two moving blocks 12 will be converted into horizontal linear movement in the opposite or approaching directions. The moving blocks 12 will drive the arc-shaped clamping blocks 13 to move synchronously, so that the wheel hub can be clamped and fixed by the two approaching arc-shaped clamping blocks 13. Start the motor 15, and the motor 15 will drive the transmission worm 16 to rotate through the coupling. Since there is a worm drive between the transmission worm gear 17 and the transmission worm 16, it will drive the transmission worm gear 17 to rotate the rotating shaft 18 synchronously. The rotating shaft 18 will drive the clamping seat 6 to rotate synchronously, so that the fixed wheel hub can be rotated to the rear side. Start the hydraulic cylinder 2 to lower the pressure gauge 3, and the pressure of the wheel hub can be detected through the pressure gauge 3. At this time, the operator can place the next wheel hub to be detected on the upper end of the base 1 and clamp and fix it by rotating the knob 10, quickly completing the fixation of the wheel hub. The operator can be protected by the transparent protection plate 5, which can avoid accidents caused by mistakes and failures, ensure the safety of the operator, and improve the safety protection. When the detection is completed, the operator can start the motor to rotate the clamping seat 6 by another 180 degrees, and the detected wheel hub can be rotated to the front. At this time, the operator can quickly conduct the next detection, and the previously detected wheel hub can be replaced during the detection, realizing disassembly and assembly while detecting, improving the detection efficiency, and the disassembly, assembly and adjustment are convenient, only by rotating the knob 10 can it be completed.
