Description

Technical Field

[0001] The utility model relates to the technical field of oil injection and press-fitting, in particular to an automatic servo pneumatic oil injection and press-fitting device. Background Art

[0002] An oil seal is the customary term for a general seal. Simply put, it is the seal of lubricating oil. It is a mechanical component used to seal grease. It isolates the components that need lubrication in the transmission components from the output components, so as to prevent the leakage of lubricating oil. The seals used for static and dynamic seals are called oil seals. At present, when using oil seals for workpieces, an oil seal injection and press-fitting integrated machine is often used.

[0003] The patent with the application number 202120954291.3 discloses an oil seal injection and press-fitting integrated machine, including a bottom plate. A working box is fixedly connected to the top of the bottom plate. A worm is connected through the outer surface of the working box. A worm gear is meshed and connected to the outer surface of the worm. A bearing is movably connected to the outer surface of the worm gear. The back of the bearing is fixedly connected to the inner surface of the working box. In this oil seal injection and press-fitting integrated machine, by placing the workpiece on the movable plate and pulling the rotating plate to the right, the telescopic rod and the first spring are extended. The rotating plate is rotated to drive the rotation of the telescopic rod. The rotation of the telescopic rod drives the rotation of the threaded rod. The rotation of the threaded rod drives the leftward movement of the moving block. The movement of the moving block drives the leftward movement of the second spring. The leftward movement of the second spring drives the leftward movement of the second fixed block. As the second fixed block moves leftward, the second spring is compressed under force.

[0004] The above technical solution uses a worm gear and a worm to drive the press head and the oil seal to move downward for press-fitting. However, since the oil seal needs to bear impact force and extrusion force during the press-fitting process, the oil seal is extremely prone to damage during use. Therefore, this application provides an automatic servo pneumatic oil injection and press-fitting device to meet the requirements. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an automatic servo pneumatic oil injection and press-fitting device to solve the problem that the existing oil seal is extremely prone to damage during use because it needs to bear impact force and extrusion force during the press-fitting process.

[0006] To solve the above technical problem, the utility model provides the following technical solutions:

[0007] An automatic servo pneumatic oil injection and press-fitting device, comprising a base and an oil pressure frame fixed to the top end of the base. A processing platform is fixed to the bottom end of the oil pressure frame, and a hydraulic rod is fixed to the top end of the oil pressure frame. A lifting frame is installed at the bottom end of the hydraulic rod. Buffer plates are fixedly embedded at both ends of the lifting frame, and a load-bearing block is threadedly inserted at the bottom end of the lifting frame. A sealing head is fixed to the bottom end of the lifting frame, and the bottom end of the load-bearing block is snugly inserted into the sealing head.

[0008] Optionally, a storage box is installed at the bottom end of the base, and a sealing door is hingedly installed on the side wall of the storage box.

[0009] Optionally, safety light curtains are symmetrically fixed to the side wall of the processing platform, and infrared sensors are equidistantly installed between the two safety light curtains.

[0010] Optionally, legs are fixedly arranged in a rectangular array at the bottom end of the base, and support seats are threadedly inserted at the bottom ends of the plurality of legs.

[0011] Optionally, a control box is fixedly installed on the side wall of the oil pressure frame, and an indicator light is installed on the top end of the control box.

[0012] Optionally, fans are embedded and installed on the side walls of the control box and the storage box, and dust-proof plates are fixed to the fans.

[0013] Optionally, a connecting plate is fixedly sleeved at the top end of the lifting frame, and a telescopic rod and a cylinder are respectively fixed on both sides of the top end surface of the connecting plate.

[0014] Optionally, the cylinder is fixedly connected to the top end of the oil pressure frame, and the top end of the telescopic rod is slidably sleeved with a fixed pipe.

[0015] Optionally, the top end of the fixed pipe is fixedly connected to the oil pressure frame, and a screw rod is symmetrically installed between the two buffer plates.

[0016] Optionally, bolts are arranged in a circular array at both ends of the lifting frame, and the plurality of bolts are respectively threadedly inserted into the two buffer plates.

[0017] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0018] In the above solution, by fixing a hydraulic rod at the top end of the oil pressure frame, after the hydraulic rod is started, it drives the lifting frame to move downward, and during the moving process, the sealing head at the bottom end of the lifting frame presses and processes the oil seal parts. During the press-fitting process, the load-bearing block bears most of the impact force, and at the same time, the two buffer plates buffer the impact on the lifting frame. When the load-bearing block is damaged, the bolts are unscrewed and the sealing head is disassembled, and after disassembly, the load-bearing block is unscrewed and removed from the bottom end of the lifting frame for replacement. This greatly reduces the impact force borne by the sealing head during use and improves the service life of the sealing head.

[0019] A safety light curtain is symmetrically arranged at the top of the processing platform, and the infrared sensor between the two safety light curtains is used for detection. During the press-fitting process, when an object passes between the two safety light curtains, the light is blocked, so that the indicator light at the top of the control box gives an alarm, improving the safety of the oil pressure equipment. A cylinder is fixed at the top of the oil pressure rack. After the cylinder is started, it drives the lifting frame to move synchronously, and adjusts the height of the lifting frame during the movement. During the adjustment process, the telescopic rod at the top of the connecting plate slides synchronously in the fixed pipe, improving the stability of the movement of the lifting frame.

[0033] Such as Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides an automatic servo pneumatic oil injection and press-fitting device, which includes a base 1 and an oil pressure frame 4 fixed to the top end of the base 1. A processing platform 6 is fixed to the bottom end of the oil pressure frame 4, and a hydraulic rod 16 is fixed to the top end of the oil pressure frame 4. A lifting frame 19 is installed at the bottom end of the hydraulic rod 16. Buffer plates 17 are embedded and fixed at both ends of the lifting frame 19, and a load-bearing block 18 is threadedly inserted at the bottom end of the lifting frame 19. A sealing head 10 is fixed to the bottom end of the lifting frame 19, and the bottom end of the load-bearing block 18 is fitted into the sealing head 10 in a matching manner. After the hydraulic rod 16 is started, it drives the lifting frame 19 to move downward, and during the movement, the sealing head 10 at the bottom end of the lifting frame 19 presses and processes the oil seal parts. During the press-fitting process, the load-bearing block 18 bears most of the impact force, and at the same time, the two buffer plates 17 buffer the impact on the lifting frame 19. When the load-bearing block 18 is damaged, the bolt 20 is unscrewed and the sealing head 10 is disassembled.

[0034] A storage box 8 is installed at the bottom end of the base 1. A sealing door is hinged and installed on the side wall of the storage box 8. Safety light curtains 5 are symmetrically fixed on the side wall of the processing platform 6. Infrared sensors are installed at equal intervals between the two safety light curtains 5. Legs 9 are fixed to the bottom end of the base 1 in a rectangular array. Support seats 7 are threadedly inserted at the bottom ends of multiple legs 9. A control box 2 is fixedly installed on the side wall of the oil pressure frame 4. An indicator light 3 is installed on the top end of the control box 2.
