DETAILED DESCRIPTION

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] like Figure 1-18 As shown, the present invention discloses a press-fitting machine including a frame 1, on which a positioning mechanism 2 movable along the Y-axis direction and a moving mechanism 3 movable along the X-axis direction are provided. The moving mechanism 3 includes a lifting drive member 31, and an output end of the lifting drive member 31 is detachably connected to a press-fitting mechanism 4;

[0040] Among them, the positioning mechanism 2 includes an upper pressure plate 21 and a lower pressure plate 22 which are arranged parallel to each other in the upper and lower directions. An elastic support member 23, a positioning sleeve 24 and a positioning seat 25 are provided between the upper pressure plate 21 and the lower pressure plate 22. One end of the positioning sleeve 24 is fixedly connected to the lower pressure plate 22, and the other end passes through the upper pressure plate 21. One end of the elastic support member 23 is fixedly connected to the lower pressure plate 22, and the other end is movably connected to the upper pressure plate 21, so that the upper pressure plate 21 is floatingly installed above the lower pressure plate 22. The pressing mechanism 4 includes a pressing block 43, a support block 44, a moving block 45 slidingly connected to the support block 44, and a driving member three 46 for driving the moving block 45 to move. The moving block 45 is also provided with a pressing head one 41 and a pressing head two 42 which are respectively arranged in a one-to-one correspondence with the positioning sleeve 24 and the positioning seat 25.

[0041] Specifically, if Figure 2-3 As shown, the press-fitting block 43 is provided with a second through hole 431 , and the driving shaft of the third driving member 46 passes through the second through hole 431 and is fixedly connected to the moving block 45 .

[0042] like Figure 4-10 As shown, during press-fitting, the component to be press-fitted is fixed on the upper press plate 21. In this embodiment, the component to be press-fitted is a vehicle frame 5, and the vehicle frame 5 includes a press-fitting position 1 51 and a press-fitting position 2 52. The press-fitting position 1 51 needs to press-fit the bearing 7, and the press-fitting position 2 52 needs to press-fit the bushing 8. The vehicle frame 5 is fixed on the upper press plate 21 so that the press-fitting position 1 51 is aligned with the positioning sleeve 24, and the press-fitting position 2 52 is aligned with the positioning seat 25. The press-fitting block 43 is fixedly connected to the moving block 45. The driving member 3 46 drives the moving block 45 to move and then drives the pressure head 1 41 to move so that it is on the same axis as the press-fitting block 43. The operator places the bearing 7 The pressing head 41 is placed at the position, and the lifting drive member 31 moves the pressing mechanism 4 to the positioning sleeve 24, and presses the bearing 7 into the pressing position 51 of the frame 5; the lifting drive member 31 rises, and the driving member 3 46 drives the moving block 45 to move so that the pressing head 42 and the pressing block 43 are on the same axis. The operator places the bushing 8 on the positioning seat 25, and the lifting drive member 31 moves the pressing mechanism 4 to the top of the positioning seat 25, contacts the pressing position 2 52 of the frame 5, and presses the frame 5 downward so that the bushing 8 placed on the positioning seat 25 is pressed into the pressing position 2 52 of the frame 5.

[0043] Preferably, a fixing frame 28 for fixing the vehicle frame 5 is provided on the upper pressing plate 21 , so that the vehicle frame 5 is not easily dropped or moved during the press-fitting process, thereby improving the press-fitting accuracy.

[0044] Preferably, an orientation column 251 is provided on the positioning seat 25. After the orientation column 251 is inserted into the inner hole of the bushing 8, it can ensure that the bushing 8 and the positioning seat 25 are coaxial. In the subsequent pressing process, the pressing force can act evenly along the axis of the bushing 8, avoiding problems such as deformation of the bushing 8 due to eccentricity, inadequate pressing or damage to the parts to be pressed, thereby ensuring the pressing quality and improving the product qualification rate.

[0045] Specifically, if Figure 4-5 As shown, the elastic support member 23 includes a guide column 231 and a spring 26. The spring 26 is sleeved on the guide column 231. One end of the spring 26 abuts against the upper pressure plate 21, and the other end abuts against the lower pressure plate 22, so that the upper pressure plate 21 can float under the guidance of the elastic support member 23, and after the press-fitting is completed, the upper pressure plate 21 can return to the initial position under the action of the spring 26 for the next installation.

[0046] Preferably, the elastic support members 23 are provided at four right angles between the upper pressing plate 21 and the lower pressing plate 22, so that the upper pressing plate 21 moves more smoothly during the press-fitting process, thereby improving the press-fitting accuracy.

[0047] Preferably, sensor 1 211 and sensor 2 212 are provided on the upper pressure plate 21, and sensor 1 211 is used to detect whether the bearing 7 is pressed into the press-fitting position 1 51, and sensor 2 212 is used to detect whether the bushing 8 is pressed into the press-fitting position 2 52. By designing sensor 1 211 and sensor 2 212, it is possible to monitor in real time whether the bearing 7 and bushing 8 are pressed into place, ensure that the press-fitting quality meets the requirements, and avoid damage to the workpiece or performance problems caused by inadequate press-fitting or excessive press-fitting.

[0048] Preferably, the positioning mechanism 2 is detachably connected to the frame 1. When different accessories need to be pressed, the positioning mechanism 2 and the pressing mechanism 4 are disassembled and replaced with matching mechanisms, so that the pressing machine can adapt to accessories of different shapes, sizes and pressing requirements. When a variety of different accessories need to be pressed, the matching positioning mechanism 2 and pressing mechanism 4 can be quickly disassembled and replaced, reducing equipment adjustment time and downtime, improving production efficiency, avoiding the configuration of a special pressing machine for each different pressing task, and reducing the overall cost of the equipment.

[0049] Preferably, a handle 223 is provided on the lower pressure plate 22 of the positioning mechanism 2. When disassembling and replacing the positioning mechanism 2, the operator can extract the entire positioning mechanism 2 through the handle 223. The handle 223 provides the operator with a stable gripping point. During the process of extracting the positioning mechanism 2, the operator can more accurately control the direction and force of extraction, which helps to avoid unnecessary collisions and damage to the positioning mechanism 2 or peripheral equipment components during the disassembly process, thereby ensuring the overall integrity of the equipment.

[0050] Specifically, if Figure 11-12 As shown, in order to facilitate the operator to place the bushing 8, the positioning seat 25 needs to have a certain distance from the bushing 8. When performing the press-fitting operation, the positioning seat 25 is lifted up to press the bushing 8. Therefore, a lifting mechanism 6 is also provided between the positioning seat 25 and the lower pressing plate 22, and the lifting mechanism 6 includes a support plate 1 61 and a support plate 2 62 arranged in parallel above and below. The support plate 1 61 is fixedly connected to the positioning seat 25, and the support plate 2 62 is fixedly connected to the lower pressing plate 22. A guide rod 63 is also provided between the support plate 1 61 and the support plate 2 62, and one end of the guide rod 63 is fixedly connected to the support plate 2 62, and the other end is movably connected to the support plate 1 61. A pushing component 64 is provided between the support plate 1 61 and the support plate 2 62, and the pushing component 64 includes a pushing block 1 641 and a driving member 1 642. The bottom of the support plate 1 61 is fixedly connected to the pushing block 641 and the driving member 1 The push block 2 611 is adapted to the block 1 641, and the output shaft of the driving member 1 642 is fixedly connected to the push block 1 641 to drive the push block 1 641 to be slidably connected to the push block 2 611; when in use, the output shaft of the driving member 1 642 drives the push block 1 641 to move, and the push block 1 641 abuts against the push block 2 611 to lift the support plate 1 61 upward, thereby driving the positioning seat 25 fixed on the support plate 1 61 to lift upward, so that the bushing 8 placed on the positioning seat 25 is in a suitable position for press-fitting, and by setting the lifting mechanism 6, there is enough space between the positioning seat 25 and the lower pressing plate 22 for the operator to place the bushing 8, and by setting the guide rod 63, the support plate 1 61 provides a stable guide during the rising and falling process, preventing the movement from offsetting during the press-fitting process, resulting in inadequate press-fitting, reducing errors and deviations during the press-fitting process, and improving the press-fitting accuracy.

[0051] Furthermore, a first inclined surface 644 is provided on the push block 1 641, and a second inclined surface 612 corresponding to the first inclined surface 644 is provided on the push block 2 611. This inclined surface contact mode enables the horizontal movement force of the push block 1 641 to be smoothly converted into the vertical lifting force of the push block 2 611 and the support plate 1 61. Compared with the direct vertical thrust transmission, the transition of the inclined surface is smoother, which reduces the impact and vibration caused by the sudden change of force, is beneficial to protecting equipment parts and extending the service life.

[0052] Furthermore, an L-shaped fixed block 621 is fixedly connected to the support plate 2 62, and slide bars 643 adapted to the fixed block 621 are provided on both sides of the push block 1 641. By setting the fixed block 621, the horizontal movement range of the push block 1 641 is limited to prevent it from excessive displacement or deviation from the predetermined trajectory during the pushing process, thereby ensuring the stable movement of the push block 1 641 and the normal operation of the jacking mechanism 6. At the same time, the sliding cooperation between the fixed block 621 and the slide bar 643 can effectively reduce the shaking of the push block 1 641 during the movement, improve the guiding effect, and make the movement of the support plate 1 61 and the positioning seat 25 smoother.

[0053] Specifically, if Figure 13-14 As shown, since the positioning sleeve 24 and the positioning seat 25 are at a certain distance on the Y axis, when the bushing 8 is pressed after the bearing 7 is pressed, the positioning mechanism 2 needs to move along the Y axis so that the pressing mechanism 4 can reach the top of the positioning seat 25 under the movement of the lifting drive member 31. Therefore, the positioning mechanism 2 includes a transmission assembly 27, and the transmission assembly 27 includes a driving member 271, a screw rod 272, a nut 273 and a connecting block 274. The driving member 271 drives the screw rod 272 to rotate to drive the nut 273 sleeved on the screw rod 272 and the nut 273 connected to the screw rod 274. The connecting block 274 fixedly connected to the mother 273 moves along the Y-axis direction, and the bottom of the lower pressure plate 22 is fixedly connected to a mounting plate 221, and the mounting plate 221 is fixedly connected to the connecting block 274. Therefore, the movement of the transmission component 27 drives the positioning mechanism 2 to move along the Y-axis direction. The automatic movement of the positioning mechanism 2 is achieved through the transmission component 27, which reduces the labor intensity of the operator, improves production efficiency, and reduces labor costs. At the same time, precise movement control reduces waste and rework caused by position deviation, reduces production costs, and makes the pressure head 1 41 and the pressure head 2 42 correspond one-to-one to the positioning sleeve 24 and the positioning seat 25.

[0054] Furthermore, the frame 1 is provided with a slide rail 11, and the bottom of the mounting plate 221 is fixedly connected with a slider 222 adapted to the slide rail 11, so that the positioning mechanism 2 can move steadily and smoothly along the Y-axis direction, ensuring the stability and accuracy of the press-fitting process. Through the precise cooperation between the slide rail 11 and the slider 222, the error in the movement process is effectively reduced, so that the press-fitting mechanism 4 can accurately reach the predetermined press-fitting position.

[0055] Specifically, if Figure 15 As shown, the pressing head 41 includes a base 411 and a pressing block 412 that are detachably connected to each other. A positioning column 413 is provided at the bottom of the pressing block 412. When working, the center hole of the bearing 7 is passed through the positioning column 413, and the upper end surface of the bearing 7 is connected to the lower end surface of the pressing block 412 by magnetic attraction. The pressing mechanism 4 moves downward under the drive of the lifting drive member 31 to reach the positioning sleeve 24, and presses the bearing 7 into the pressing position 51 of the frame 5.

[0056] Specifically, if Figure 16 As shown, the second pressing head 42 includes a second base 421 and a second pressing block 422 that are detachably connected to each other. A positioning groove 423 is provided at the bottom of the second pressing block 422. During press-fitting, the press-fitting mechanism 4 abuts against the vehicle frame 5, presses the vehicle frame 5 downward to the positioning seat 25, and presses the bushing 8 on the positioning seat 25 into the second pressing position 52 to achieve press-fitting of the bushing 8.

[0057] Specifically, if Figure 17-18 As shown, since the positioning sleeve 24 and the positioning seat 25 are at a certain distance in the X-axis direction, in order to realize the press-fitting of the two accessories of the bearing 7 and the bushing 8 at different positions, the moving mechanism 3 also includes a positioning assembly 33, and the positioning assembly 33 includes a driving member 4 331, a screw rod 2 332, a nut 2 333 and a vertical plate 334. The driving member 4 331 drives the screw rod 2 332 to rotate to drive the nut 2 333 mounted on the screw rod 2 332 and the vertical plate 334 fixedly connected to the nut 2 333 to move along the X-axis direction.

[0058] Furthermore, the moving mechanism 3 includes a horizontal plate 32 , a through hole 1 321 is provided on the horizontal plate 32 , the lifting driving member 31 passes through the through hole 1 321 and is connected to the pressing mechanism 4 , and the horizontal plate 32 is fixedly connected to the vertical plate 334 .

[0059] Furthermore, the frame 1 is provided with a slide rail 2 12, and the cross plate 32 is provided with a slider 2 322 fixedly connected to the slide rail 2 12. Through the cooperation between the slider 2 322 and the slide rail 2 12, the mobile mechanism 3 provides a guide and route for the movement of the mobile mechanism 3, and the movement in the X-axis direction is more stable.

[0060] Furthermore, the end portion of the lifting drive member 31 connected to the pressing mechanism 4 is provided with a positioning block 311 adapted to the pressing block 43. The positioning block 311 is detachably connected to the pressing block 43. Accessories of different shapes and sizes often require matching pressing blocks 43 to ensure the pressing effect. Through this detachable design, the same set of moving mechanisms 3 can be matched with a variety of pressing blocks 43 of different specifications, thereby meeting the needs of various pressing tasks, greatly improving the versatility and utilization of the equipment, and reducing the cost investment incurred by the enterprise in purchasing multiple sets of special equipment.

[0061] The working principle of the present invention is described in detail below;

[0062] During press-fitting, the component to be press-fitted is fixed on the upper press plate 21. In this embodiment, the component to be press-fitted is the vehicle frame 5, which includes a press-fitting position 1 51 and a press-fitting position 2 52. The press-fitting position 1 51 needs to press-fit the bearing 7, and the press-fitting position 2 52 needs to press-fit the bushing 8. The vehicle frame 5 is fixed on the upper press plate 21 so that the press-fitting position 1 51 is aligned with the positioning sleeve 24, and the press-fitting position 2 52 is aligned with the positioning seat 25. The press-fitting block 43 is fixedly connected to the moving block 45. The driving member 3 46 drives the moving block 45 to move and then drives the pressure head 1 41 to move so that it is on the same axis as the press-fitting block 43. The operator places the bearing 7 At the pressure head 1 41, the lifting drive member 31 moves the pressing mechanism 4 to the positioning sleeve 24, and presses the bearing 7 into the pressing position 1 51 of the frame 5; the lifting drive member 31 rises, and the drive member 3 46 drives the moving block 45 to move so that the pressure head 2 42 and the pressing block 43 are on the same axis. The operator places the bushing 8 on the positioning seat 25, and the lifting drive member 31 moves the pressing mechanism 4 to the top of the positioning seat 25, contacts the pressing position 2 52 of the frame 5, and presses the frame 5 downward so that the bushing 8 placed on the positioning seat 25 is pressed into the pressing position 2 52 of the frame 5.

[0063] The innovation of the present invention lies in that the pressing mechanism is designed to be detachably connected to the lifting drive shaft, which makes it easy to replace and disassemble the pressing mechanism to adapt to accessories of various models and sizes, and the pressing head one and the pressing head two are switched by the driving member three to realize the pressing of two different accessories, and the switching process is convenient; the upper pressing plate is floatingly installed above the lower pressing plate through an elastic support member, and can automatically adjust its position during the pressing process to ensure high-precision positioning.
