Description

Technical Field

[0001] This utility model relates to the field of vehicle opening bushing processing technology, specifically a vehicle opening bushing press-fitting tool. Background Technology

[0002] Vehicle open bushing press-fitting fixture is a specialized piece of equipment used for press-fitting open bushings onto automobiles and other vehicles. Its main function is to ensure that the open bushing is accurately and stably press-fitted onto the relevant vehicle components through precise control and mechanical structure.

[0003] For example, Chinese Patent Application No. 201921363000.2 discloses a bushing press-fitting fixture. The bushing press-fitting fixture includes a positioning rod with upper and lower guides mounted on a press-fitting worktable or guide pillars on the worktable, and a spring acting on the positioning rod. The positioning rod has a large-diameter section and a small-diameter section. The small-diameter section is used to fit with the bushing to be pressed, and the large-diameter section is used to fit with a circular hole on the part to be press-fitted. The bushing is fitted onto the small-diameter section, and the part to be press-fitted is placed on the press-fitting worktable and fitted onto the large-diameter section. A driving device presses down the positioning rod and the bushing to achieve press-fitting assembly of the part and the bushing. During this assembly process, the bushing and the circular hole on the part have a high degree of coaxiality, which can prevent the bushing from being deformed or damaged, improving the assembly quality of the bushing. Moreover, the positioning rod and the bushing are driven downwards by the driving device, which can reduce the labor intensity of workers and improve the assembly efficiency of the bushing.

[0004] In the use of vehicle open bushing pressing fixtures, traditional pressing fixtures in car repair shops usually rely on jacks to complete the pressing operation. While this method is stable and allows for easy replacement of damaged jacks, it is not only time-consuming and labor-intensive, but also has poor stability when the entire device is placed vertically on the ground. It is very easy for it to tip over under external forces, which may lead to safety accidents or damage to the equipment.

[0005] Therefore, it is necessary to redesign and modify the tooling for pressing open bushings on vehicles to effectively prevent it from being time-consuming, labor-intensive, and prone to tipping over. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a vehicle open bushing pressing tool, which has the advantages of being easy to use and solves the problems of being time-consuming, labor-intensive, and prone to tipping over.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vehicle open bushing press-fitting fixture, comprising a base, a fixture mounted on the top of the base, and a conversion mechanism. The conversion mechanism includes a slider slidably connected to the inner wall of the base, a screw threadedly connected to the inner wall of the slider, the surface of the screw being movably connected to the inner wall of the base via a bearing, a sliding plate fixedly connected to the top of the slider, limit frames slidably connected to both sides of the sliding plate, the bottom of the limit frames being fixedly connected to the top of the base, a base plate fixedly connected to the top of the sliding plate, a jack placed on the front side of the top of the base plate, and a hydraulic cylinder fixedly connected to the rear side of the top of the base plate. When the screw rotates, the base plate can be moved forward by the slider, thereby flexibly switching between the jack and the hydraulic cylinder. Stable support mechanisms are provided on the left and right sides of the base.

[0008] As a preferred embodiment of this utility model, the stable support mechanism includes support blocks fixedly connected to the left and right sides of the base.

The rear ends of each round rod are fixedly connected to worm gears. The tops of each worm gear are engaged with worms. The surface of the worms is movably connected to a support frame via bearings. The inner side of the support frame is fixedly connected to the surface of the base. A drive mechanism is provided on the rear side of the base.

[0009] As a preferred embodiment of this utility model, the drive mechanism includes a fixing block fixedly connected to the back of the base, a motor fixedly connected to the top of the fixing block, and spur gears fixedly connected to the front output shaft of the motor and the rear end of the screw. The inner sides of the spur gears mesh with each other, and a clutch control mechanism is provided on the rear side of the base.

[0010] As a preferred embodiment of this utility model, the clutch control mechanism includes a first bevel gear fixedly connected to the front of the upper spur gear.

A control plate is sleeved on the surface of the sleeve. When the second bevel gear moves to the left, it can mesh with the first bevel gear, thereby driving the support foot to lower through the worm gear, thus increasing the support stability of the left and right sides of the base.

[0011] As a preferred embodiment of this invention, a handle is fixedly connected to the top of the control panel, which can conveniently move the control panel.

[0012] As a preferred embodiment of this invention, a protective box is provided on the top of the motor, and the bottom of the protective box is fixedly connected to the top of the base.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, the present invention provides a vehicle opening bushing pressing fixture, including a base 1, a fixture 2 mounted on the top of the base 1, and a conversion mechanism. The conversion mechanism includes a slider 3 slidably connected to the inner wall of the base 1, a screw 4 threadedly connected to the inner wall of the slider 3, and the surface of the screw 4 movably connected to the inner wall of the base 1 via a bearing. A sliding plate 5 is fixedly connected to the top of the slider 3, and limit frames 6 are slidably connected to both the left and right sides of the sliding plate 5. The bottom of the limit frames 6 is fixedly connected to the top of the base 1. A base plate 7 is fixedly connected to the top of the sliding plate 5. A jack 8 is placed on the front side of the top of the base plate 7, and a hydraulic cylinder 9 is fixedly connected to the rear side of the top of the base plate 7. When the screw 4 rotates, the base plate 7 can be moved forward by the slider 3, thereby flexibly switching between the jack 8 and the hydraulic cylinder 9. Stable support mechanisms are provided on the left and right sides of the base 1.

[0024] refer to Figure 4 The stabilizing support mechanism includes support blocks 10 fixedly connected to the left and right sides of the base 1. The inner walls of the support blocks 10 are slidably connected to round rods 11. The tops of the round rods 11 are fixedly connected to four support feet 12. The rear ends of the round rods 11 are fixedly connected to worm gears 13. The tops of the worm gears 13 are meshed with worms 14. The surface of the worms 14 is movably connected to a support frame 15 through bearings. The inner side of the support frame 15 is fixedly connected to the surface of the base 1. A drive mechanism is provided on the rear side of the base 1.

[0025] As a technical optimization of this utility model, by setting a stable support mechanism, the support points on the left and right sides of the base 1 are increased. When the support foot 12 is lowered, the stability of the base 1 can be significantly improved, preventing the device from tilting or shaking during operation. It is especially suitable for working environments with uneven ground or requiring greater support force, ensuring the safety and reliability of the device.

[0026] refer to Figure 4 The drive mechanism includes a fixed block 16 fixedly connected to the back of the base 1. A motor 17 is fixedly connected to the top of the fixed block 16. A spur gear 18 is fixedly connected to the front output shaft of the motor 17 and the rear end of the screw 4. The inner sides of the spur gear 18 mesh with each other. A clutch control mechanism is provided on the rear side of the base 1.

[0027] As a technical optimization of this utility model, by setting up a drive mechanism and using the motor 17 as a power source, it has the advantages of stable power output and strong controllability. Through the meshing of the spur gears 18, the power of the motor 17 is transmitted to the screw 4. This transmission method has a simple structure and high transmission efficiency, and can accurately convert the rotational motion of the motor 17 into the rotational motion of the screw 4.

[0028] refer to Figure 5The clutch control mechanism includes a bevel gear 19 fixedly connected to the front of the upper spur gear 18. A transmission rod 20 is provided on the front side of the bevel gear 19. The left and right ends of the transmission rod 20 are fixedly connected to the inner side of the worm gear 14. A bevel gear 21 is slidably connected to the surface of the transmission rod 20. A sleeve 22 is fixedly connected to the right side of the bevel gear 21. A control plate 23 is sleeved on the surface of the sleeve 22. When the bevel gear 21 moves to the left, it can mesh with the bevel gear 19, thereby driving the support foot 12 to be lowered through the worm gear 14, thereby increasing the support stability of the left and right sides of the base 1.

[0029] As a technical optimization of this utility model, a clutch control mechanism is set up to control the worm gear 14 transmission. When it is necessary to increase the support stability, the bevel gear 21 is engaged with the bevel gear 19 by moving the control plate 23, thereby activating the worm gear 14 transmission and driving the support foot 12 to lower.

[0030] refer to Figure 5 A handle 24 is fixedly connected to the top of the control panel 23, which can easily move the control panel 23.

[0031] As a technical optimization of this utility model, by setting a handle 24, the operator can easily move the control plate 23 by using the handle 24, thereby controlling the operation of the clutch control mechanism.

[0032] refer to Figure 1 The top of the motor 17 is provided with a protective box 25, and the bottom of the protective box 25 is fixedly connected to the top of the base 1.

[0033] As a technical optimization of this utility model, the protective box 25 effectively protects the motor 17. The protective box 25 can prevent the motor 17 and its internal structure from being corroded by external dust, debris, moisture, etc.

[0034] The working principle and usage process of this utility model are as follows: When the motor 17 is running, its output shaft drives the spur gear 18 connected to it to rotate. Because the spur gear 18 meshes with the spur gear 18 at the rear end of the screw 4, the screw 4 rotates accordingly. The slider 3, which is threadedly connected to it, slides on the inner wall of the base 1, causing the top sliding plate 5 to move forward stably under the limiting action of the limiting frame 6. This, in turn, causes the bottom plate 7 on top of the sliding plate 5 to move. When the bottom plate 7 moves forward, the hydraulic cylinder 9, which was originally in the rear position, moves forward relative to the front, and the jack 8 placed in the front moves outside the tooling 2, realizing the flexible switching of the working states of the jack 8 and the hydraulic cylinder 9. At the same time, the clutch control mechanism... Initially, bevel gear 21 is not engaged with bevel gear 19. When it is necessary to lower the support feet 12 to increase support stability, the control plate 23 is moved by the handle 24. The control plate 23 drives the sleeve 22 and the bevel gear 21 connected to it to move to the left, so that bevel gear 21 and bevel gear 19 mesh together. At this time, the motor 17 runs, which in turn drives the transmission rod 20 to rotate through the clutch control mechanism. The worm 14 connected to the worm gear 13 also rotates. The worm 14 drives the worm gear 13 to rotate, and the worm gear 13 drives the round rod 11 to flip downward. The four support feet 12 at the top of the round rod 11 are then lowered, increasing the support stability on the left and right sides of the base 1. This avoids the inconvenience of manual operation and easy tipping caused by the vehicle open bushing pressing tool 2, and makes it easy to use.

[0035] In summary, this invention, through the coordinated operation of the conversion mechanism, support and stabilization mechanism, drive mechanism, and clutch control mechanism, allows for flexible switching between manual and automatic operation modes. In manual mode, operational stability is ensured; in automatic mode, the pressing of open bushings is completed efficiently. Furthermore, the device incorporates a support and stabilization structure, effectively enhancing the stability of the left and right sides of the base, preventing inconvenience caused by the tooling easily tipping over due to external forces, and significantly improving ease of use.
