Detailed Implementation

[0017] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0018] Please see Figure 1-3 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0019] Please see Figures 1 to 3This utility model provides a gear-type chamfering positioning fixture 1000, including a base 1 and a gear 2 detachably mounted on the base 1. The base 1 includes a worktable 11; a rotating shaft 12 is vertically arranged on the worktable 11, and the gear 2 is sleeved on the rotating shaft 12; the gear 2 includes a gear body 21 and a plurality of gear teeth 22, the gear teeth 22 are arranged on the outer circumferential surface of the gear body 21 with the rotating shaft 12 as the axis, and the worktable 11 is provided with a plurality of positioning holes 111 corresponding to the gear teeth 22.

[0020] By designing positioning holes 111 corresponding to gear teeth 22, the gear 2 is accurately positioned. When gear teeth 22 are processed again, they can be firmly fixed on the base 1 without slippage, which greatly improves the processing accuracy of gear teeth 22.

[0021] Please see Figure 3 The gear 2 includes a protrusion 23, which is located on the side of the gear 2 away from the base 1. The protrusion 23 has a fixing hole 231, which, when engaged with a bolt, allows for a detachable connection between the gear 2 and the rotating shaft 12. Once all the teeth 22 on a gear 2 have been machined, the gear 2 is removed from the rotating shaft 12, and a new, unmachined gear 2 is reinstalled on the rotating shaft 12 and enters the machining process again.

[0022] Furthermore, a gear-type chamfering positioning fixture 1000 also includes a positioning pin 3, and a through hole 211 is provided on the gear body 21; the positioning pin 3 passes through the through hole 211 and extends into the positioning hole 111. Through the cooperation of the positioning pin 3, the through hole 211 and the positioning pin 3, each gear tooth 22 can be accurately positioned during processing; the cooperation of the fixing hole 231 and the bolt makes the connection between the gear 2 and the rotating shaft 12 more stable.

[0023] Please continue reading. Figure 2 The base 1 has a clearance groove 13 on the side near the gear 2. The clearance groove 13 is designed to allow the milling device to process the gear teeth 22 without being blocked by the base 1.

[0024] Please continue reading. Figure 1 A gear-type chamfering positioning fixture 1000 further includes a rotary drive unit 4, the output end of which is connected to the rotary shaft 12 for transmission. In a preferred embodiment, the rotary drive unit 4 is a stepper motor. The stepper motor drives the rotary shaft 12 to rotate, thereby driving the gear 2 to rotate. After each tooth 22 is machined, the gear rotates by a predetermined angle.

[0025] The implementation principle of the gear-type chamfering positioning fixture 1000 in this utility model is as follows: the gear 2 is sleeved on the rotating shaft 12, and the positioning pin 3 passes through the through hole 211 and extends into the positioning hole 111 to position the gear 2. Then, the connection between the gear 2 and the rotating shaft 12 is reinforced by the cooperation of the bolt and the fixing hole 231. After the gear 2 is fixed, the gear teeth 22 are processed. After one gear tooth 22 is processed, the stepper motor drives the gear 2 to rotate at a predetermined angle, so that the unprocessed gear teeth 22 face the processing equipment. This process is repeated multiple times until all gear teeth 22 are processed. The technician removes the processed gear 2 from the base 1 and puts in a new unprocessed gear 2.

[0026] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
