Description

Technical Field

[0001] This utility model relates to the field of bushing press technology, and in particular to a subframe body bushing press. Background Technology

[0002] In the automotive manufacturing industry, the subframe, as a key component connecting the vehicle body and the suspension, directly affects the vehicle's driving stability, comfort, and safety in terms of its assembly quality. The connection between the subframe and the vehicle body is achieved through bushings. The pressing accuracy and stability of the bushings are the core aspects of ensuring the function of the subframe. During the bushing pressing process, the bushings must be precisely embedded into the corresponding bushing holes of the subframe, and stable pressure must be applied to ensure a tight fit, so as to avoid problems such as loosening and abnormal noises during later use.

[0003] The existing equipment for pressing subframe bushings typically consists of a fixed worktable, a simple hydraulic press head, and a manual positioning device. The technical principle is to place the subframe on the fixed worktable, manually adjust the position of the subframe so that the bushing hole is aligned with the press head, and then start the hydraulic press head to apply pressure to the bushing to complete the pressing.

[0004] However, existing bushing pressing equipment requires repeated adjustments to the subframe posture when pressing bushings at different positions on the subframe. This not only results in high labor intensity but also easily leads to insufficient bushing pressing accuracy due to positioning deviations, affecting the assembly quality and production efficiency of the subframe. Therefore, a subframe body bushing press is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a subframe body bushing press, which aims to improve the problem in the prior art that when it is necessary to press bushings at different positions of the subframe, the subframe posture needs to be repeatedly adjusted, which affects the assembly efficiency of the subframe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A subframe body bushing press includes a machine body and a servo rotary table. A protective net is fixedly connected inside the machine body. A symmetrical safety light grid is provided on one side of the protective net. A sliding plate is slidably connected inside the machine body. A subframe body is provided on the top of the servo rotary table. A pressing component is provided at the bottom of the sliding plate. A positioning component is provided on the top of the servo rotary table.

[0008] The pressing assembly includes a first pressing head and a second pressing head. The top of the first pressing head is fixedly connected to the bottom of the slide plate, and the second pressing head is located at the bottom of one side of the slide plate. A servo electric cylinder is fixedly connected inside the machine body. The top of the slide plate is fixedly connected to the output end of the servo electric cylinder. An adjustment assembly is provided inside the slide plate, and a drive assembly is provided on the top of the slide plate.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes a slider that is slidably connected inside the slide plate, and the top of the second pressure head is fixedly connected to the bottom of the slider.

[0011] As a further description of the above technical solution:

[0012] The drive assembly includes an electric push rod, the bottom of which is fixedly connected to the top of the slide plate, and a connecting rod is fixedly connected to the output end of the electric push rod.

[0013] As a further description of the above technical solution:

[0014] A connecting block is fixedly connected to one side of the slider, and one end of the connecting rod is fixedly connected to one side of the connecting block.

[0015] As a further description of the above technical solution:

[0016] The positioning component includes multiple positioning cylinders, the bottoms of which are fixedly connected to the top of the servo rotary table.

[0017] As a further description of the above technical solution:

[0018] Multiple positioning cylinders are arranged in a circular array on the top of the servo rotary table, and the tops of the multiple positioning cylinders are respectively inserted into the corresponding bushing holes of the subframe body.

[0019] As a further description of the above technical solution:

[0020] The bottom of the servo rotary table is fixedly connected to a chassis, and the top of the servo rotary table is fixedly connected to a guardrail.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by activating the electric push rod and driving the connecting block through the connecting rod, the slider slides in the slide plate to adjust the position of the pressure head. The adjusted pressure head is aligned with the target bushing and cooperates with another pressure head to complete the pressing. This achieves the effect of adapting to the pressing needs of bushings of different sizes, and solves the problem that the pressure head position of traditional pressing equipment is fixed and cannot adapt to the pressing of bushings of different sizes on the subframe. This improves the applicability of the subframe body bushing press.

[0023] 2. In this utility model, by placing the subframe body on the top of the rotary table and fixing it with a positioning cylinder inserted into the bushing hole, the rotary table rotates and drives the subframe to rotate when pressing bushings at different positions, moving the part to be pressed to below the press head, thus achieving the effect of continuous pressing of bushings at different positions of the subframe, thereby improving the production efficiency of subframe bushing pressing.

[0030] 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.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a subframe body bushing press, including a machine body 1 and a servo rotary table 2. The servo rotary table 2 can drive the subframe to rotate to meet the pressing requirements of bushings at different positions. A protective net 3 is fixedly connected inside the machine body 1 to isolate the internal working area of ​​the press from the outside, preventing debris from splashing during the pressing process and causing safety hazards, while not affecting the observation of the internal working conditions. A symmetrical safety light grid 4 is set on one side of the protective net 3, which forms a protective barrier by emitting and receiving infrared beams. This is existing technology and will not be described in detail here. A sliding plate 5 is slidably connected inside the machine body 1. The subframe body 12 is set on the top of the servo rotary table 2. A pressing component is set at the bottom of the sliding plate 5. A positioning component is set on the top of the servo rotary table 2.

[0032] The pressing assembly includes a first pressing head 7 and a second pressing head 8. The top of the first pressing head 7 is fixedly connected to the bottom of the slide plate 5, which can apply stable pressure to the bushing to ensure that the bushing is tightly embedded in the bushing hole. The second pressing head 8 is located on the bottom side of the slide plate 5 and is used to cooperate with the first pressing head 7 to complete the pressing of bushings of different sizes. A servo cylinder 6 is fixedly connected inside the machine body 1. The top of the slide plate 5 is fixedly connected to the output end of the servo cylinder 6. When the servo cylinder 6 is working, it drives the slide plate 5 to slide up and down to realize the pressing and resetting action of the pressing head. An adjustment assembly is provided inside the slide plate 5 to adjust the position of the second pressing head 8 to adapt to bushings in different positions. A drive assembly and adjustment assembly are provided on the top of the slide plate 5. The system includes a slider 10, which is slidably connected inside the slide plate 5 to provide stable guidance for adjusting the position of the second pressure head 8. The top of the second pressure head 8 is fixedly connected to the bottom of the slider 10. The drive assembly includes an electric push rod 16, the bottom of which is fixedly connected to the top of the slide plate 5. A connecting rod 9 is fixedly connected to the output end of the electric push rod 16. A connecting block 11 is fixedly connected to one side of the slider 10. One end of the connecting rod 9 is fixedly connected to one side of the connecting block 11. When the electric push rod 16 extends or retracts, it drives the slider 10 to slide through the connecting rod 9 and the connecting block 11, thereby adjusting the position of the second pressure head 8 so that it can be accurately aligned with the bushings at different positions, improving the adaptability of the equipment.

[0033] Reference Figure 1 and Figure 4 The positioning assembly includes multiple positioning cylinders 15, the bottom of which are fixedly connected to the top of the servo rotary table 2. Driven pneumatically, these cylinders offer flexible extension and retraction and stable thrust. The cylinders 15 are arranged in a circular array on the top of the servo rotary table 2. The tops of the cylinders 15 are inserted into corresponding bushing holes in the subframe body 12, ensuring positioning of the subframe body 12 from multiple points. Insertion effectively restricts the horizontal displacement and rotation of the subframe body 12, preventing wobbling or displacement during pressing and ensuring pressing accuracy. A housing 13 is fixedly connected to the bottom of the servo rotary table 2, providing power for its rotation and protecting internal components. A guardrail 14, a circular metal guardrail, is fixedly connected to the top of the servo rotary table 2, surrounding the subframe body 12 to prevent accidental slippage during rotation or pressing, further improving equipment safety.

[0034] Working principle: When using this subframe body bushing press, the subframe body 12 is first placed on the top of the servo rotary table 2. Multiple positioning cylinders 15 are inserted into the corresponding bushing holes of the subframe body 12 to secure the subframe body 12 on the servo rotary table 2. Then, the bushing is placed in the corresponding bushing hole. At this time, the servo electric cylinder 6 operates, pushing the slide plate 5 to slide inside the machine body 1. The first pressure head 7 moves down with the slide plate 5 to press the corresponding bushing on the subframe body 12. When pressing bushings of different positions or sizes, the electric push rod 16 is activated, which drives the connecting block 11 through the connecting rod 9, so that the slider 10 slides inside the slide plate 5. Then, the position of the second pressure head 8 is adjusted so that the second pressure head 8 is aligned with the target bushing. It works with the first pressure head 7 to complete the pressing operation of different bushings and meet various pressing requirements.

[0035] Once a bushing is pressed, the servo rotary table 2 rotates, causing the subframe body 12 to rotate. This moves the next bushing to be pressed to a position below the first pressure head 7 or the adjusted second pressure head 8, and the pressing operation continues until all bushings on the subframe body 12 are pressed, thus achieving continuous processing.
