Description

Technical Field

[0001] This utility model relates to the field of press-fitting equipment technology, specifically a rapid press-fitting machine for automotive oil seals. Background Technology

[0002] Oil seals are mechanical components used to seal grease. They isolate lubricated parts from power-output parts in transmission components to prevent lubricating oil leakage.

[0003] Currently, pressing equipment is generally required to install oil seals into workpieces. Traditional pressing equipment includes pneumatic and manual methods. Manual pressing equipment is mostly used for pressing oil seals into small workpieces. When using pressing equipment to press oil seals into workpieces, users need to first place the workpiece on the platform, then place the oil seal on the mounting hole groove above the workpiece, and press down the pressure plate to press the oil seal into the mounting hole groove of the workpiece. It lacks a structure that allows for quick alignment. During use, operators need to spend a long time adjusting and correcting the relative positions of the workpiece and the oil seal, which undoubtedly reduces the efficiency of pressing oil seals into individual workpieces.

Detailed Implementation

[0024] 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.

[0025] This embodiment discloses a rapid pressing machine for automotive oil seals, including a placement seat 1 and a cavity 2 located on top of the placement seat 1. A sleeve 3 is slidably connected to the top of the cavity 2, and a lifting mechanism 4 is provided inside the cavity 2. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown in this application, the cavity 2 is used for the installation and fixation of the lifting mechanism 4, and the cavity 2 and the sleeve 3 are slidably connected. The cavity 2 limits the direction of movement of the sleeve 3. The lifting mechanism 4 is designed inside the cavity 2 and is used to drive the sleeve 3 to move up and down on the cavity 2 to achieve the purpose of adjusting the height of the sleeve 3.

[0026] Furthermore, the lifting mechanism 4 includes a rotating shaft 41, which is rotatably connected to the cavity 2. A transmission gear 42 is fixedly sleeved on the surface of the rotating shaft 41. The surface of the sleeve 3 is provided with a toothed groove 43 that meshes with the transmission gear 42. One end of the rotating shaft 41 extends through to the outside of the cavity 2 and is fixedly sleeved with a pressing handle 24. The top of the placement seat 1 is fixedly connected to a support seat 25 that is fixedly connected to the cavity 2. Figure 1 , Figure 4 and Figure 6As shown, in this application, the support base 25 is installed between the placement base 1 and the cavity 2 for supporting and fixing the cavity 2. The pressing handle 24 is installed on the rotating shaft 41. When the user presses the pressing handle 24, it can drive the pressing handle 24 to rotate around the rotating shaft 41, so that the rotating shaft 41 rotates accordingly. When the rotating shaft 41 rotates, the transmission gear 42 installed on the rotating shaft 41 rotates around the rotating shaft 41. The center position of the transmission gear 42 remains unchanged. Under the action of the tooth groove 43, the sleeve 3 is driven to adjust its height.

[0027] Furthermore, the cavity 2 is internally fitted with a guide block 18, and the surface of the sleeve 3 is provided with a guide groove 19 that slides in connection with the guide block 18, such as... Figure 3 and Figure 6 As shown in this application, when the sleeve 3 is adjusted in height by the lifting mechanism 4, the sleeve 3 can be slidably limited and prevented from rotating.

[0028] More specifically, one end of the sleeve 3 extends to the bottom of the cavity 2 and is fixedly fitted with a pressure block 5. The bottom of the pressure block 5 has multiple grooves 6, and an adjusting screw 7 is connected inside each groove 6. A connecting block 8, which is slidably connected to the groove 6, is screwed onto the surface of the adjusting screw 7. A locking block 9 is fixedly connected to the bottom of the connecting block 8. An adjusting mechanism 10 is provided in the groove at the bottom of the pressure block 5. A rotating rod 11 is connected inside the sleeve 3. Multiple limiting sleeves 12 are fixedly connected to the surface of the pressure block 5. A limiting rod 13 is provided inside each limiting sleeve 12. A supporting spring 14 is locked between the limiting rod 13 and the limiting sleeve 12. The top of the placement seat 1 has limiting grooves 15 corresponding to the number and position of the limiting sleeves 12. A push block 16 is fixedly connected to the bottom of the limiting rod 13. A locking block 17, which is slidably connected to the push block 16, is provided inside the limiting groove 15. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the rotating rod 11 is rotatably connected to the inside of the sleeve 3 via a bearing. The adjusting screw 7 is set inside the groove 6, preferably four grooves 6. The connecting block 8 is threadedly connected to the surface of the adjusting screw 7 for connecting and fixing the locking block 9. The adjusting mechanism 10 is designed in the groove at the bottom of the pressure block 5. When the rotating rod 11 is rotated by the user, the adjusting mechanism 10 can drive the four adjusting screws 7 to rotate simultaneously, thereby causing the connecting block 8 to move the locking block 9, adjusting the distance between the four locking blocks 9. When the inner diameter of the oil seal is locked between the four locking blocks 9, the rotating rod 11 rotates, causing the four locking blocks 9 to contact the inner wall of the oil seal, thus fixing the oil seal at the center position at the bottom of the pressure block 5. After the oil seal is fixed, the workpiece is placed on the placement seat 1 and positioned between multiple locking blocks 17, preferably four locking blocks 17. The limiting rod 13 is located inside the limiting sleeve 12 and is slidably connected to the limiting sleeve 12. When the pressure block 5 is pressed down, it can drive the limit rod 13 on the limit sleeve 12 to press down. The push block 16 is installed at the bottom of the limit rod 13, so the limit rod 13 can drive the push block 16 to descend. When the push block 16 descends and contacts the locking block 17 installed inside the limit groove 15 at the top of the placement seat 1, due to the special shape of the push block 16 and the locking block 17, the four locking blocks 17 move, shortening the distance between the four locking blocks 17, pushing the workpiece placed on the top of the placement seat 1 to the center position corresponding to the pressure block 5, so that the installation position of the workpiece is the same as the axis of the oil seal. There is no need for the staff to spend a long time adjusting and correcting the relative positions of the workpiece and the oil seal. Moreover, due to the design of the support spring 14, when the locking block 17 contacts the workpiece surface and cannot move, the position of the push block 16 remains unchanged. When the pressure block 5 continues to press down, the limit rod 13 can retract into the limit sleeve 12 to prevent affecting the pressing operation of the pressure block 5.

[0029] Furthermore, a guide rod 20 is fixedly connected inside the limiting groove 15 and slidably connected to the locking block 17. A return spring 21 is sleeved on the surface of the guide rod 20. Sliding blocks 22 are symmetrically assembled on the surface of the limiting rod 13. A sliding groove 23 is opened inside the limiting sleeve 12 and slidably connected to the sliding block 22. Figure 2 As shown, when the push block 16 pushes the locking block 17 to move inside the limiting groove 15 under the action of the inclined surface, the locking block 17 slides on the surface of the guide rod 20, and the guide rod 20 slides and limits the locking block 17. When the limiting rod 13 retracts into the limiting sleeve 12, the sliding block 22 and the sliding groove 23 can slide and limit the limiting rod 13 to prevent the limiting rod 13 from rotating when it retracts, causing the inclined surface of the push block 16 and the inclined surface of the locking block 17 to be mismatched.

[0030] Furthermore, the adjusting mechanism 10 includes a first bevel gear 101, which is disposed in a groove at the bottom of the pressure block 5. One end of the rotating rod 11 passes through the groove at the bottom of the pressure block 5 and is fixedly sleeved with the first bevel gear 101. One end of the adjusting screw 7 passes through the groove at the bottom of the pressure block 5 and is fixedly sleeved with a second bevel gear 102 that meshes with the first bevel gear 101. Figure 3 and Figure 4 As shown, when the user rotates the rotating rod 11, one end of the rotating rod 11 is fixedly sleeved with the first bevel gear 101. The rotation of the rotating rod 11 can drive the first bevel gear 101 to rotate. The rotation of the first bevel gear 101 can drive the second bevel gear 102 meshed with the tooth surface of the first bevel gear 101 to rotate. Since the second bevel gear 102 is fixedly sleeved with the adjusting screw 7, it drives the adjusting screw 7 to rotate, so that it can drive the connecting block 8 to move inside the groove 6, thereby driving the locking block 9 to move.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
