Description

Technical Field

[0001] The present application relates to the technical field of sleeve pressing equipment, and in particular to a multi-platform sleeve pressing machine. Background Art

[0002] Reference Figure 1 The bushing 200 at the rotating connection between the shaft head and the cylinder bottom of the hydraulic cylinder 100 and other equipment plays a key supporting and connecting role in the hydraulic system. The bushing 200 is usually used to reduce the friction between the shaft head and the cylinder bottom and the connected equipment to ensure smooth rotational movement. The bushing 200 usually needs to be pressed into the holes of the shaft head and the cylinder bottom earrings to ensure a tight fit between the bushing 200 and the earrings. During the pressing process, a swaging machine is usually used to ensure that the bushing 200 can be pressed into the earring hole evenly and smoothly to avoid damage to the bushing 200 or the earring.

[0003] For related technology, please refer to the Chinese patent announcement number CN220740086U, which discloses an elastic sleeve device for engine connecting rod production, including a workbench, with mounting tables arranged in front and back on the workbench for convenient placement of workpieces, a longitudinal moving mechanism arranged on the workbench outside the mounting table, a support frame arranged above the longitudinal moving mechanism, a transverse screw drive mechanism arranged on the support frame, a vertical screw drive mechanism arranged on the transverse screw drive mechanism, a sleeve pressing mechanism arranged on the vertical screw drive mechanism, a bearing platform arranged on the mounting table, a T-shaped positioning seat and a hollow cylindrical carrying plate arranged on the left and right of the carrying plate, a lifting plate arranged at the geometric center of the carrying plate, a positioning rod arranged at the lower end of the lifting plate, the outer sleeve of the positioning rod is provided with a telescopic spring, and an adapter block is also provided in the carrying plate located at the outer periphery of the lifting plate.

[0004] With respect to the above-mentioned related technologies, it is usually necessary to use manual labor or turnover equipment to place the products to be processed on the sleeve pressing device. In batch processing, turnover equipment is often used to transport workpieces due to the high labor intensity and low production efficiency of the product turnover process when manual labor is used. The turnover equipment uses a conveyor line to transport the workpiece from a workstation to the sleeve pressing device and ensure that the workpiece is accurately positioned within the working area of ​​the sleeve pressing machine. When the turnover equipment transports workpieces of different heights to the sleeve pressing device, it is necessary to adjust the position and height of the clamping components on the conveyor line to clamp the workpiece so that the lower end of the workpiece is adapted to the height of the workbench. However, there are a large number of clamping components on the conveyor line and it is inconvenient to adjust the position. Utility Model Content

[0005] In order to improve the adaptability and ease of operation of the equipment, the present application provides a multi-platform sleeving machine.

[0006] This application provides a multi-platform sleeving machine, which adopts the following technical solutions:

[0007] A multi-platform sleeve pressing machine includes a workbench, a mounting plate and a supporting plate. The mounting plate is located above the workbench and is slidably connected to the workbench in the horizontal direction. The supporting plate is fixed to the upper end surface of the mounting plate. The upper end surface of the mounting plate is provided with a vertical plate. The vertical plate and the supporting plate are arranged on the mounting plate along the sliding direction of the mounting plate. The side of the vertical plate close to the supporting plate is slidably connected to a sleeve pressing cylinder in the vertical direction. A pressing plate is provided at the telescopic shaft end of the sleeve pressing cylinder. The pressing plate is located above the supporting plate and moves in the vertical direction. A lifting component for driving the workbench to rise and fall is provided under the workbench.

[0008] By implementing this technical solution, the worktable's lifting and lowering functions, combined with the lifting and lowering of the sleeve-pressing cylinders, and coordinated with the turnover equipment, optimize and automate the production process. Once a hydraulic cylinder completes its sleeve-pressing operation, the turnover equipment immediately removes it and moves the next hydraulic cylinder to the carrier plate. The sleeve-pressing cylinder then prepares for the next sleeve-pressing operation, pressing the sleeve into the cylinder's earring, enabling continuous production. The mounting plate drives the carrier plate and sleeve plate for horizontal movement, accommodating sleeve-pressing operations for hydraulic cylinders of varying sizes. This reduces the need to adjust the position of the clamping assembly on the turnover device, improving the equipment's adaptability and ease of operation. The sleeve-pressing cylinders slide on the vertical plates, adjusting the distance between the sleeve and the carrier plate. This allows for sleeve-pressing operations with cylinders of varying diameters, further enhancing the equipment's adaptability. Furthermore, when sleeve-pressing smaller quantities or individual workpieces, manual loading allows the worktable's height to be adjusted, allowing the operator to operate at a safe and comfortable height, reducing labor intensity and improving work safety.

[0010] By adopting the above technical solution, the driving device drives the elevator to work, the elevator drives the screw to move up and down, thereby driving the workbench to move up and down, so that the workbench can achieve stable lifting movement, thereby improving the adaptability of the sleeve pressing machine to different turnover equipment.

[0011] Optionally, the elevator includes a shell, a worm gear and a worm, the shell is fixedly connected to the support plate, the worm gear and the worm are located in the shell and mesh with each other, the worm is rotatably connected to the shell along its own axis, the worm gear is rotatably connected to the shell along a vertical axis, one end of the worm is connected to the driving device, and the worm gear is threadedly connected to the screw.

[0012] By adopting the above technical solution, the driving device drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the screw to rise and fall, thereby driving the workbench to rise and fall. When the worm stops rotating, the worm wheel will not rotate on its own, thereby achieving a self-locking effect and improving the stability of the equipment.

[0013] Optionally, there are two elevators, which are located on both sides of the support plate. Both worm gears are connected to a connecting rod through a coupling. The connecting rod and the worm gear are coaxially arranged, and one end of the worm gear away from the connecting rod is connected to the driving device.

[0014] By adopting the above technical solution, two elevators are set up and located on both sides of the support plate respectively. The two worm gears are connected with a connecting rod through a coupling, which ensures the synchronous operation of the two elevators and improves the stability and reliability of the workbench lifting.

[0015] Optionally, the driving device is a handwheel.

[0016] By adopting the above technical solution, the handwheel as a driving device can be directly manually rotated by the operator to realize the lifting and lowering operation of the workbench, which simplifies the structure of the equipment, reduces the manufacturing cost of the equipment, and makes the operation simpler and more intuitive.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] The embodiment of the present application discloses a multi-platform sleeving machine.

[0035] Reference Figure 2 A multi-platform swagging machine includes a workbench 1, a mounting plate 2, and a support plate 3. The support plate 3 is bolted to the upper end surface of the mounting plate 2, allowing for easy removal and replacement. A vertical plate 4 is provided on the upper end surface of the mounting plate 2. The vertical plate 4 and the support plate 3 are arranged on the mounting plate 2 along the sliding direction of the mounting plate 2. The vertical plate 4 is fixedly connected to the mounting plate 2 by bolts. A rib is provided on the side of the vertical plate 4 away from the support plate 3 to enhance the stability of the vertical plate 4.

[0036] Reference Figure 2 A pressing cylinder 5 is installed on the side of the vertical plate 4 close to the load-bearing plate 3. A pressing plate 51 is installed at the end of the telescopic shaft of the pressing cylinder 5. The pressing plate 51 is located above the load-bearing plate 3. The pressing cylinder 5 drives the pressing plate 51 toward or away from the load-bearing plate 3, causing the pressing plate 51 to move in the vertical direction. A hydraulic cylinder 100 is placed on the load-bearing plate 3, and a bushing 200 is placed on the earring of the hydraulic cylinder 100. The pressing cylinder 5 drives the pressing plate 51 downward, pressing the bushing 200 into the earring of the hydraulic cylinder 100. A reinforcing plate is provided at the lower end of the load-bearing plate 3 to enhance the load-bearing plate 3's ability to resist bending.

[0037] Reference Figure 2 The body of the sleeve pressing cylinder 5 is fixed with a connecting plate, the vertical plate 4 is provided with a vertical through slot, and the connecting plate is provided with a through hole. The connecting plate and the vertical plate 4 are fixed together by passing a bolt through the through hole and the through slot and then tightening the nut. At the same time, by loosening the nut, the connecting plate is moved up and down to achieve the function of sliding the sleeve pressing cylinder 5 up and down, so that the sleeve pressing machine can adapt to the sleeve pressing operation of hydraulic cylinders 100 of different diameters, thereby improving the adaptability of the equipment.

[0038] Reference Figure 2 and Figure 3The mounting plate 2 is located above the workbench 1. Two parallel slide rails are provided on both sides of the upper end surface of the workbench 1. The lower end surface of the mounting plate 2 is provided with a slide seat sliding on the slide rails, so that the mounting plate 2 is slidably connected to the workbench 1 in the horizontal direction, so that the sleeve pressing machine can adapt to the sleeve pressing operation of hydraulic cylinders 100 of different lengths, thereby improving the adaptability of the equipment.

[0039] Reference Figure 2 A lifting assembly 6 is provided under the workbench 1 for driving the workbench 1 to move up and down. The lifting assembly 6 includes a support plate 61, an elevator 62, a screw 63 and a driving device 64.

[0040] Reference Figure 4 The elevator 62 includes a housing 621, a worm gear 622, and a worm 623. The housing 621 is fixed to the upper end surface of the support plate 61 by bolts. The worm gear 622 and worm 623 are located within the housing 621 and mesh with each other. The worm 623 is rotationally connected to the housing 621 along its own axis, and the worm gear 622 is rotationally connected to the housing 621 along a vertical axis. The worm gear 622 is threadedly connected to the screw 63. The upper end of the screw 63 is fixedly connected to the workbench 1, and the lower end of the screw 63 passes through the support plate 61 and is slidably connected to the support plate 61 in the vertical direction.

[0041] Reference Figure 3 and Figure 4 Two elevators 62 are mounted on the upper end surface of the support plate 61. The two elevators 62 are located on either side of the support plate 61. Two worm gears 623 are coaxially arranged, and the two worm wheels 622 rotate in the same direction. A connecting rod 66 is coaxially arranged between the two worm gears 623. Both worm gears 623 are connected to the connecting rod 66 via a coupling 65. This ensures the synchronous operation of the two elevators 62, improving the stability and reliability of the lifting of the workbench 1.

[0042] Reference Figure 2 The driving device 64 can be a hand wheel, which can be directly rotated manually by the operator to realize the lifting operation of the workbench 1, simplifying the structure of the equipment, reducing the manufacturing cost of the equipment, and making the operation more simple and intuitive.

[0043] Reference Figure 3 and Figure 4 One end of a worm 623, away from the connecting rod 66, is coaxially connected to a handwheel. An operator manually turns the handwheel, which drives the worm 623 to rotate. The worm 623 then drives the worm wheel 622 to rotate. The worm wheel 622 then drives the screw 63 up and down, thereby driving the workbench 1 up and down. This allows the workbench 1 to achieve stable lifting motion, thereby improving the swager's adaptability to various types of rotating equipment. When the worm 623 stops rotating, the worm wheel 622 will not rotate on its own, thereby achieving a self-locking effect and improving the stability of the equipment.

[0044] Reference Figure 2 The support plate 61 is located below the workbench 1. Four support columns 611 are fixedly mounted on the lower end of the support plate 61, one at each corner of the support plate 61. A sliding column 11 is inserted into each support column 611, and the upper end of the sliding column 11 is fixedly connected to the lower end of the workbench 1. When the workbench 1 is raised or lowered, the workbench 1 drives the sliding column 11 to slide up and down within the support columns 611, ensuring the stability and guidance of the workbench 1 during the raising and lowering process, preventing the workbench 1 from deflecting or shaking during the raising and lowering process, and improving the accuracy and reliability of the sleeve pressing operation.

[0045] Reference Figure 2 and Figure 5 The bottom surface of the support column 611 is fixedly provided with a base plate 7. Four movable wheels are provided at the bottom end of the base plate 7. These movable wheels include two first universal wheels 8 and two second universal wheels 9. The two first universal wheels 8 are located at the ends of one side of the base plate 7, and the two second universal wheels 9 are located at the ends of the side of the base plate 7 away from the first universal wheels 8. The first universal wheels 8 are provided with brake devices 91. The four movable wheels are located at the four corners of the base plate 7 to provide stable support for the swagging machine. By providing different types of movable wheels, stable and flexible movement is achieved. The brake devices 91 ensure safe fixation during operation.

[0046] Reference Figure 2 The workbench 1 and the support plate 61 are provided with a plurality of weight-reducing holes 12. The weight-reducing holes 12 on the workbench 1 are circular, and the weight-reducing holes 12 on the support plate 61 are rounded rectangles. This reduces the weight of the workbench 1 and the support plate 61, thereby reducing the weight of the entire swagging machine, making it easier for workers to move the swagging machine and lift the workbench 1. This also reduces material usage and saves production costs.

[0047] The implementation principle of a multi-platform sleeve pressing machine in an embodiment of the present application is as follows: the combination of the lifting of the workbench 1 and the lifting of the sleeve pressing cylinder 5, as well as the coordination with the turnover equipment, makes the production process more optimized and automated. When a hydraulic cylinder 100 completes the sleeve pressing operation, the turnover equipment can immediately remove it and send the next hydraulic cylinder 100 to the bearing plate 3. The sleeve pressing cylinder 5 is then ready to perform the next sleeve pressing operation to press the bushing 200 into the earring of the hydraulic cylinder 100, thereby realizing continuous production. The mounting plate 2 drives the bearing plate 3 and the pressing plate 51 to move horizontally, adapting to the sleeve pressing operation of hydraulic cylinders 100 of different sizes, while reducing the adjustment of the position of the clamping assembly on the turnover device, thereby improving the adaptability and ease of operation of the equipment. The sleeve pressing cylinder 5 slides on the vertical plate 4, and the distance between the sleeve pressing cylinder 5 and the bearing plate 3 can be adjusted, which can adapt to the sleeve pressing operation of hydraulic cylinders 100 of different diameters, thereby improving the adaptability of the equipment. At the same time, when pressing a small number of or individual workpieces, manual loading is used and the height of the workbench 1 can be adjusted so that the operator can operate at a safe and comfortable height, reducing the operator's labor intensity and improving work safety.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
