DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The embodiment of the present application provides a processing tool for processing eccentric pins, which solves the problem that traditional eccentric pin processing tools often require multiple clamping and positioning during use due to the structural characteristics of the eccentric pin, which increases the auxiliary time in the processing process. Since the workpiece needs to be clamped and positioned multiple times, each clamping may produce slight position deviations. These deviations may cause the final processing accuracy to fail to meet the design requirements after accumulation.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model embodiment discloses a processing tool for processing an eccentric pin. Figure 1-4 As shown, it includes end covers 2 sleeved on both sides of the eccentric pin body 1, a card slot 101 is opened on the side wall of the eccentric pin body 1, and a card block 201 is provided inside the end cover 2, and the card block 201 is card-engaged with the card slot 101;

[0026] A center plate 4 is movably connected to the side wall of the end cover 2, and a center shaft 5 is arranged inside the center plate 4. A clamping hole corresponding to the center shaft 5 is opened on the center plate 4. The center shaft 5 is fixed in the clamping hole. The center shaft 5 is connected to the motor drive shaft. The motor drive shaft drives the center shaft 5 to rotate, thereby driving the center plate 4, the end cover 2 and the eccentric pin body 1 to rotate, thereby realizing eccentric processing of the eccentric pin body 1.

[0027] A positioning groove 202 corresponding to the center plate 4 is provided on the end cover 2, and a fixing component is provided between the end cover 2 and the center plate 4. The fixing component includes a limiting screw hole 2021 provided in the positioning groove 202 and a positioning screw 6 movably inserted on the center plate 4. The positioning screw 6 is threadedly connected with the limiting screw hole 2021, and a circular hole corresponding to the position of the positioning screw 6 is provided on the center plate 4. The design of the positioning screw 6 makes it convenient to tighten and fix the position after the end cover 2 and the center plate 4 are clamped together, so that the center shaft 5 drives the center plate 4, the end cover 2 and the eccentric pin body 1 to rotate for eccentric processing.

[0028] The interior of the positioning groove 202 is fixedly connected with a reinforcement column 3, and an embedding groove 401 is opened on the center plate 4. The reinforcement column 3 is movably snapped into the embedding groove 401. Through the snap-fit ​​design of the reinforcement column 3 and the embedding groove 401, when the end cover 2 is snapped into the center plate 4, a snap-fit ​​limit is provided to ensure that the end cover 2 and the center plate 4 are easy to snap into.

[0029] A locking groove 301 is provided on the reinforcement column 3, and a limiting sleeve 7 is fixedly connected to the center plate 4. A spring 701 is provided inside the limiting sleeve 7, and a slider 702 is fixedly connected to the spring 701. The slider 702 is slidably connected inside the limiting sleeve 7 and fixedly connected to a wedge block 703. The wedge block 703 is movably engaged in the locking groove 301, and a push handle 704 is fixedly connected to the slider 702.

[0030] When the end cover 2 is clamped with the center plate 4, the reinforcement column 3 is clamped in the embedding groove 401, and the reinforcement column 3 applies a thrust to the inclined surface of the wedge block 703, so that the wedge block 703 drives the slider 702 to move and squeezes the spring 701. When the reinforcement column 3 is completely clamped in the embedding groove 401, the wedge block 703 is aligned with the locking groove 301, and the spring 701 is reset and pushes the slider 702 and the wedge block 703 to move, so that the wedge block 703 is inserted into the locking groove 301, thereby temporarily fixing the reinforcement column 3 and the center plate 4, which is convenient for the subsequent fixing with the positioning screw 6. Pushing the push handle 704 can move the slider 702 and the wedge block 703 and unlock the clamping position of the reinforcement column 3.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
