[0022] In combination with the attached Figures 1-5 , this embodiment proposes a bearing punching tool, which includes three parts: a tooling main body 10, a guiding rod 11, and a punch head 12. Among them, a force-bearing end 101 is fixedly arranged at the top of the tooling main body 10 for bearing the knocking of tools such as hammers. A first mounting hole 111 and several second mounting holes 112 are arranged on the tooling main body 10. The openings of the first mounting hole 111 and the second mounting holes 112 are located at the bottom of the tooling main body 10. The first mounting hole 111 is used for fixedly installing the guiding rod 11, and several second mounting holes 112 are arranged around the first mounting hole 111. The second mounting holes 112 are used for fixedly installing the punch head 12.
[0023] Based on the above basic structural description, the implementation method of the bearing punching tool in this embodiment is as follows: Taking the punching of the GE4C spherical plain bearing as an example, a first mounting hole 111 with a diameter of 4 mm and a depth of 36 mm, and four second mounting holes 112 with a diameter of 4 mm and a depth of 15 mm are provided on the lower end face of the tooling main body 10. Machine or select a guiding rod 11 with a diameter of 4 mm and a length of 43 mm. The material of the guiding rod 11 is preferably 45# steel. Machine or select 4 punch heads 12 with a diameter of 4 mm and a length of 20 mm. Preferably, the material of the punch head 12 is bearing steel, and the hardness after heat treatment meets HRC58 - 62.
[0024] A first threaded hole 121 and several second threaded holes 122 are provided on the side wall of the tooling main body 10. The number of the second threaded holes 122 is the same as the number of the second mounting holes 112. The first threaded hole 121 is perpendicular to and communicates with the first mounting hole 111, and the second threaded holes 122 are perpendicular to and communicate with the second mounting holes 112. Thus, the guiding rod 11 can be assembled with the first mounting hole 111 through the cooperation of the first threaded hole 121 and threaded connectors such as screws. Similarly, the punch head 12 can be assembled with the second mounting hole 112 through the cooperation of the second threaded hole 122 and threaded connectors such as screws. Since the punching work will cause the punch head 12 to wear relatively fast, the bearing punching tool in this embodiment can disassemble and replace the punch head 12 and the guiding rod 11 separately, which can save costs.
[0025] Among them, more preferably, the diameter of the first threaded hole 121 is smaller than the diameter of the first mounting hole 111, and the diameter of the second threaded hole 122 is smaller than the diameter of the second mounting hole 112. The relatively smaller first threaded hole 121 and second threaded holes 122 can satisfy the fixation of the guiding rod 11 and the punch head 12.
[0026] When performing bearing punching, fix the guiding rod 11 and the punch head 12 on the tooling main body 10 with screws respectively, then insert the guiding rod 11 into the spherical plain bearing, and use a hammer to strike the force - receiving end 101 of the bearing punching tool, then the spherical plain bearing can be punched.
[0027] In the above - mentioned embodiment, the distance that the guiding rod 11 extends beyond the bottom end face of the tooling main body 10 is greater than the distance that the punch head 12 extends beyond the bottom end face of the tooling main body 10. The purpose is to enable the guiding rod 11 to be fully inserted into the spherical plain bearing to achieve the positioning effect.
[0028] Moreover, in the above - mentioned embodiment, the depth of the first mounting hole 111 is greater than the depth of the second mounting hole 112, and the length of the guiding rod 11 is greater than the length of the punch head 12. The purpose is to ensure the stability of the guiding rod 11, so that it can meet better stability, and thus ensure the positioning accuracy of the punch head 12.
[0029] Also, in the above embodiment, the diameter of the first mounting hole 111 is equal to the diameter of the second mounting hole 112, and the diameter of the guide rod 11 is equal to the diameter of the pressure head 12, which helps to improve the convenience of processing. When processing the tooling body 10, only one hole diameter needs to be considered.
[0030] The pressure head 12 in this embodiment is used to directly contact the bearing and serve as the main working part of the punching point. The end of the pressure head 12 away from the tooling body 10 is a conical cone head. The generatrix angle α of the cone head can be 45°-75°. When 60° is selected, it can meet the punching point requirements for the GE4C joint bearing in the example implementation method.
[0031] In addition, preferably, a gripping section 102 is fixedly provided between the tooling body 10 and the force-bearing end 101, and the diameter of the gripping section 102 is smaller than the diameters of the tooling body 10 and the force-bearing end 101. The setting of the gripping section 102 can facilitate grasping, thereby improving the convenience of use.
[0032] Based on all the foregoing descriptions, it can be known that the bearing punching tool proposed in this embodiment can perform multiple punching operations at one time by utilizing multiple pressure heads 12, thereby improving the punching efficiency. At the same time, the position of the punching operation can be limited by setting the guide rod 11, thereby preventing the position of the punching operation from being offset and causing quality problems.
[0033] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
