[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0025] Example

[0026] refer to Figures 2-5 As shown, the present invention discloses an integrated oil injection and pressing machine, including an oil injection block 10. The upper end face of the oil injection block 10 is configured as an oil inlet end face 11, and the lower end face of the oil injection block 10 is provided with a pressing protrusion 12. The lower end face of the pressing protrusion 12 is provided with an oil injection hole 13 communicating with the oil inlet end face 11, and a rotating shaft clearance cavity 14 is provided at the center of the lower end face of the pressing protrusion 12. The rotating shaft clearance cavity 14 extends upward into the interior of the oil injection block 10. Elastic pins 30 that can move through their lower end faces are respectively provided on both sides of the pressing protrusion 12.

[0027] In practice, when part 51 is placed on the rotating shaft 50, the oil injection block 10 descends under the action of external force, and the rotating shaft 50 is inserted into the rotating shaft clearance cavity 14. The pressing protrusion 12 will contact part 51, and the two elastic pins 30 will be compressed. As the pressing protrusion 12 moves downward with part 51, the oil injection hole 13 will inject oil into the surface of part 51 until part 51 is pressed into place. When the external force drives the oil injection block 10 to retract, the pressing protrusion 12 will leave the surface of part 51, and the elastic pins 30 will gradually spring open. During this process, the pressing protrusion 12 will not take part 51 away, thus satisfying both the pressing of part 51 and the oil injection of part 51.

[0028] In one embodiment, symmetrical cutting grooves (not shown) are provided on both sides of the pressing protrusion 12. Elastic pins 30, located on both sides of the pressing protrusion 12, extend or retract within the two cutting grooves. Specifically, each elastic pin 30 includes a spring 32 and a pin body 31. A contact block 311, which can extend or retract within the cutting groove, is provided on the inner bottom of the pin body 31. A limiting block 312 is provided on the outer top of the pin body 31. Detachable clamping blocks 20 are provided on opposite sides of the oil injection block 10. A guide groove 21 is provided inside the clamping block 20, and a limiting step 22 is provided at the bottom of the guide groove 21. The pin body 31 and the limiting block 312 are retractably positioned within the guide groove 21 and are positioned by the limiting step 22. 12 is used for limiting. The oil injection block 10 is a T-shaped oil injection block 10. The spring 32 is set between the T-shaped oil injection block 10 and the limiting block 312. During the assembly process, the contact block 311 is first positioned in the cutting groove, and then the clamping block 20 is fixed to the oil injection block 10. At this time, the needle body 31 and the limiting block 312 will be placed in the guide groove 21. When the contact block 311 moves downward, the part 51 will compress the contact block 311 upward. At this time, the needle body 31 and the limiting block 312 will move upward in the guide groove 21. When the contact block 311 moves upward, the spring 32 will rebound and carry the needle body 31 and the limiting block 312 downward, so that the contact block 311 will spring the part 51 away, ensuring that the pressing protrusion 12 will not take the part 51 away.

[0029] To facilitate the assembly and disassembly of the two clamping blocks 20 and the oil injection block 10, the present invention preferably fixes the two clamping blocks 20 to the oil injection block 10 respectively by means of pins 40.

[0030] In order to reduce the contact area between the contact block 311 and the part 51, so that the pressing protrusion 12 can smoothly pop the part 51 away after pressing the part 51, the present invention provides the same chamfer structure 3111 on the opposite sides of the contact block 311.

[0031] In one specific embodiment, the bottom of the oil injection block 10 has at least eight pressing protrusions 12, and the eight pressing protrusions 12 are arranged in a straight line, which makes it convenient for one oil injection block 10 to assemble eight parts 51 on eight rotating shafts, greatly improving efficiency. In actual use, the number of pressing protrusions 12 on the oil injection block 10 is not subject to rigid requirements and can be designed according to production needs.

[0032] In another specific embodiment, the number of oil injection holes 13 on the lower end face of the pressing protrusion 12 is 8, and the 8 oil injection holes 13 are arranged in groups of four on the lower end faces of the pressing protrusion 12 on both sides of the two cutting grooves, which can ensure uniform oil injection on the part 51 and achieve better results.
