Description
Technical Field
[0001] The utility model relates to the technical field of press-fitting machines, in particular to a press-fitting machine which can prevent the oil seal lip from rolling over. Background Art
[0002] A press machine is a pressure assembly machine, which is widely used in many industries such as automotive accessories, communication products and electrical appliances. It is mainly used to install various components that require interference fit to make them reliably connected. Some press-fit work requires the use of oil seals. As a sealing component, the oil seal needs to be installed in the oil seal groove of the motor bearing cover. The quality of the oil seal assembly often determines the bearing grease sealing performance and further affects the service life of the motor.
[0003] In some existing oil seal presses, when the shaft contacts the oil seal lip and continues to press, the movement of the shaft can easily cause the oil seal lip to curl. After the oil seal curls, it loses its sealing function and needs to be reworked or the workpiece is scrapped, resulting in increased operating costs and reduced production efficiency. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a press machine that prevents the oil seal lip from rolling up, so as to solve the technical problems mentioned in the above background.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a press machine for preventing the oil seal lip from curling up, comprising a device body, a hydraulic cylinder, an electric push rod and a guide rod are installed on one side of the device body, the output end of the hydraulic cylinder is connected to a clamp, one side of the clamp is connected to a pressure plate via a first spring, the output end of the electric push rod is connected to a support frame, and a slide is connected to the inside of the support frame via a rotating shaft.
[0006] By adopting the above technical solution, the staff first pushes the material into the clamp from the feed port and tightens the bolts. Then the staff starts the hydraulic cylinder and the electric push rod. The movement of the hydraulic cylinder drives the movement of the clamp, and the movement of the electric push rod drives the movement of the support frame. The movement of the support frame causes the slide to enter the oil seal ring first. After moving a certain distance, the hydraulic cylinder drives the material to continue to move through the clamp, and the electric push rod drives the slide to be retracted to the right through the support frame. At this time, the material abuts against the slide to open the slide, and the slide abuts against the sealing lip to turn out the sealing lip. When the slide is completely moved out, the material enters the oil seal ring and the movement of the clamp drives the first spring to move. The first spring drives the pressure plate to move, and the pressure plate moves to flatten the turned-out sealing lip.
[0007] Furthermore, a material inlet is provided on one side of the device body, and bolts are provided on the outer surface of the clamp.
[0008] By adopting the above technical solution, the feed port can adapt to materials of different diameters, and the staff can tighten the clamp with bolts.
[0009] Furthermore, an oil seal ring and a guide rail are provided on one side of the device body, and a clamping plate is connected inside the guide rail via a second spring.
[0010] By adopting the above technical solution, the guide rail can facilitate the left and right movement of the clamping plate in the guide rail to support and guide the left and right sides, and the movement of the clamping plate can compress the second spring.
[0011] Furthermore, two guide rails and two card plates are provided, and the two guide rails and two card plates are distributed in a mirror image.
[0012] By adopting the above technical solution, the elastic potential energy of the second spring reset can enable the two clamping plates to clamp the oil seal ring, thereby preventing the oil seal ring from shaking and falling during the press-fitting work.
[0013] Furthermore, the guide rod passes through the clamp and the support frame, and the slide passes through the clamp.
[0014] By adopting the above technical solution, the guide rod supports and guides both the clamp and the support frame, and the slide can move left and right in the clamp.
[0015] Furthermore, four sliding plates are provided, and the four sliding plates are distributed in a ring array.
[0016] By adopting the above technical solution, the four sliding vanes distributed in a ring array can play a better role in opening the sealing lip of the oil seal, making subsequent flattening easier.
[0017] Furthermore, a lower portion of one side of the slide is sloped, and the slide is movably connected to the clamp.
[0018] By adopting the above technical solution, the inclined surface allows the slide to enter the oil seal ring with a smaller diameter, which is convenient for subsequent expansion, and the slide can move left and right in the fixture.
[0019] Furthermore, the pressure plate abuts against the oil seal ring.
[0020] By adopting the above technical solution, the movement of the clamp drives the first spring to move, the first spring drives the pressure plate to move, and the movement of the pressure plate flattens the turned-out sealing lip.
[0021] In summary, the utility model mainly has the following beneficial effects:
[0022] 1. The utility model is provided with a hydraulic cylinder, an electric push rod, a clamp, a first spring, a pressure plate, a support frame and a slide. The staff first pushes the material into the clamp from the material inlet and tightens the bolts. Then the staff starts the hydraulic cylinder and the electric push rod. The movement of the hydraulic cylinder drives the movement of the clamp. The movement of the electric push rod drives the movement of the support frame. The movement of the support frame causes the slide to enter the oil seal ring first. After moving a certain distance, the hydraulic cylinder drives the material to continue to move through the clamp. The electric push rod drives the slide to be recovered to the right through the support frame. At this time, the material abuts against the slide to open the slide, and the slide abuts against the sealing lip to turn the sealing lip out. When the slide is completely moved out and the material enters the oil seal ring, the movement of the clamp drives the movement of the first spring, and the first spring drives the pressure plate to move. The pressure plate moves to flatten the turned-out sealing lip. Through the above operation and structure, the operating cost is reduced, the production efficiency is improved, the structure is simple, and the design is reasonable.
[0023] 2. The utility model provides the guide rail, the second spring, the clamping plate and the bolt. The staff moves the two clamping plates to the left and right respectively. During the moving process, the staff places the oil seal ring on the device body. The elastic potential energy of the second spring reset can enable the two clamping plates to clamp the oil seal ring, thereby preventing the oil seal ring from shaking and falling during the press-fitting work.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0031] The following describes an embodiment of the utility model based on its overall structure.
[0032] Embodiment 1:
[0033] A press machine for preventing the oil seal lip from curling up, such as Figure 1-Figure 5 As shown, it includes a device body 1, and a hydraulic cylinder 4, an electric push rod 5 and a guide rod 6 are installed on the other side of the device body 1. The guide rod 6 supports and guides the clamp 7 and the support frame 10. The output end of the hydraulic cylinder 4 is connected to the clamp 7, and the clamp 7 can clamp the material. A slide groove is arranged in the clamp 7 to facilitate the movement of the slide 12. One side of the clamp 7 is connected to a pressure plate 9 through a first spring 8, and the pressure plate 9 can flatten the turned-out sealing lip. The output end of the electric push rod 5 is connected to the support frame 10, and the inside of the support frame 10 is connected to the slide 12 through a rotating shaft 11. The slide 12 is rotatably connected to the support frame 10.
[0034] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 In the above embodiment, a feed port 3 is provided on one side of the device body 1, and a bolt 2 is provided on the outer surface of the clamp 7. The feed port 3 can adapt to materials of different diameters. The staff can tighten the clamp 7 with the bolt 2. The guide rod 6 runs through the clamp 7 and the support frame 10, and the slide 12 runs through the clamp 7. The guide rod 6 supports and guides the clamp 7 and the support frame 10, and the slide 12 can move left and right in the clamp 7.
[0035] See also Figure 1-Figure 5 In the above embodiment, four slides 12 are provided, and the four slides 12 are distributed in a circular array. The four slides 12 distributed in a circular array can play a better role in opening the sealing lip of the oil seal ring 13, which is convenient for subsequent flattening. The lower side of the slide 12 is sloped. The slide 12 is movably connected to the clamp 7. The inclined surface allows the slide 12 to enter the oil seal ring 13 with a smaller diameter, which is convenient for subsequent opening. The slide 12 can move left and right in the clamp 7, and the pressure plate 9 is in contact with the oil seal ring 13. The movement of the clamp 7 drives the first spring 8 to move, and the first spring 8 drives the pressure plate 9 to move. The pressure plate 9 moves to flatten the turned-out sealing lip.
[0036] Embodiment 2:
[0037] On the basis of the above-mentioned embodiment 1, although the material can be pressed into the oil seal ring 13 by the arrangement of the hydraulic cylinder 4 and the clamp 7, the oil seal ring 13 may shake and fall off during the pressing process. Now, by the arrangement of the guide rail 14, the second spring 15 and the clamping plate 16, it is possible to avoid the oil seal ring 13 from shaking and falling off during the pressing work.
[0038] See also Figure 1-Figure 4In the above embodiment, an oil seal ring 13 and a guide rail 14 are provided on the other side of the device body 1. A card plate 16 is connected to the inside of the guide rail 14 through a second spring 15. The guide rail 14 can facilitate the card plate 16 to move left and right in the guide rail 14, playing a supporting and guiding role. The movement of the card plate 16 can compress the second spring 15. Two guide rails 14 and two card plates 16 are provided, and the two guide rails 14 and card plates 16 are distributed in a mirror image. The elastic potential energy of the second spring 15 resetting can enable the two card plates 16 to clamp the oil seal ring 13, so as to prevent the oil seal ring 13 from shaking and falling during the press-fitting work.
[0039] The implementation principle of the utility model is as follows: first, the staff member first moves the two clamping plates 16 to the left and right respectively. During the moving process, the staff member places the oil seal ring 13 on the device body 1. The elastic potential energy of the second spring 15 resets the two clamping plates 16 to clamp the oil seal ring 13, so as to prevent the oil seal ring 13 from shaking and falling during the press-fitting work. Then the staff member pushes the material into the clamp 7 from the feed port 3 and tightens the bolt 2. After that, the staff member starts the hydraulic cylinder 4 and the electric push rod 5. The movement of the hydraulic cylinder 4 drives the clamp 7 to move. The movement of the electric push rod 5 drives the support frame 10 to move. The movement of the support frame 10 causes the slide 12 to enter the oil first. In the sealing ring 13, after moving a certain distance, the hydraulic cylinder 4 drives the material to continue to move through the clamp 7, and the electric push rod 5 drives the slide 12 to retract to the right through the support frame 10. At this time, the material abuts against the slide 12, and the slide 12 is stretched open. The slide 12 abuts against the inside of the oil seal ring 13 to turn out the sealing lip. When the slide 12 is completely moved out, the material enters the oil seal ring 13, and at the same time, the clamp 7 moves to drive the first spring 8 to move, and the first spring 8 drives the pressure plate 9 to move. The pressure plate 9 moves to flatten the turned-out sealing lip. When the pressing work is completed, the staff tightens the bolt 2 so that the clamp 7 no longer fixes the material, and retracts the hydraulic cylinder 4 and the electric push rod 5.
