[0002] A shaft is a cylindrical object that is inserted in the middle of a bearing, a wheel, or a gear. A shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. Common shafts include gear shafts, rotating shafts, and other products. When processing an existing shaft, a shaft processing device is required, and the shaft is fixed with a fixture for processing.

[0003] The Chinese utility model patent (authorization announcement number: CN206898445U name: Shaft side hole processing jig) includes a jig body, a cavity adapted to the axial surface of the product to be processed is provided on the jig body, a through hole is provided on the side wall of the jig body, the through hole is connected to the cavity, and the position of the through hole is consistent with the position of the side hole to be processed on the axial surface of the product to be processed; a clamping structure that engages with the product to be processed is provided on the side wall of the jig body located in the cavity. When processing the side hole, the product is placed in the cavity and engaged with the clamping structure, and then the tool for processing the side hole is inserted into the cavity from the through hole and acts on the axial surface of the product to be processed. Because the product to be processed will not move easily in the cavity, the shaft side hole can be processed quickly and accurately without marking and positioning, thereby improving the processing accuracy and processing efficiency. However, when processing the side hole, since the direction of the axis centerline is not locked, the vibrating drill bit will cause the shaft to jump, affecting the quality of the drilled hole.

[0024] like Figure 1-3As shown, a servo motor output shaft processing device includes a support table 1, a sleeve 2, a connecting structure and a locking piece. The support table 1 fixes the sleeve 2 through the connecting structure. The locking piece is used to fix the output shaft in the sleeve 2. The locking piece is a tapered sleeve 3. The inner cavity of the tapered sleeve 3 is adapted to the output shaft. There are two tapered sleeves 3 and they are respectively sleeved on both ends of the output shaft. A contraction gap 4 is opened on the tapered sleeve 3. The sleeve 2 is used to narrow the contraction gap 4. The output shaft is locked in the sleeve 2 by narrowing the contraction gap 4. The contraction gap 4 is narrowed by pushing the tapered sleeve 3 into the sleeve 2, so that the output shaft to be drilled is locked in the sleeve 2. The structure is simple and the locking is fast. The locked output shaft is fixed on the support table 1 through the sleeve 2. When drilling, the axial vibration is avoided, thereby ensuring the drilling quality (the drilling position is determined in advance by marking by a fitter).

[0025] In this embodiment, if Figure 4 and 5 As shown, the sleeve 2 is composed of two sections, one end of the sleeve 2 is provided with an internal thread, and one end of the other sleeve 2 is provided with an external thread. The two sleeves 2 are connected by threads, and the effective length of the sleeve 2 is changed by rotating the two sleeves 2 relative to each other, so that the tapered sleeves 3 at both ends are tightened or unlocked, without manually knocking the tapered sleeves 3. The locking structure is simple and the output shaft is convenient to disassemble and assemble.

[0026] In this embodiment, if Figure 4 and 5 As shown, there are two types of connection structures. The first connection structure includes a pair of wing plates 5, bolts 6 and nuts 7. The wing plates 5 of the same pair are respectively fixed on both sides of the sleeve 2. A through hole is opened on the wing plate 5, and the bolt 6 is inserted into the through hole. A T-shaped groove 8 is opened on the support platform 1 along the extension direction of the sleeve 2. The nut 7 is slidably installed in the T-shaped groove 8. The sleeve 2 is locked by tightening the bolt 6 in the nut 7. The second connection structure includes a pair of wing plates 5, bolts 6 and nuts 7. The wing plates 5 of the same pair are respectively fixed on both sides of the sleeve 2. The wing plates 5 extend along the extension direction of the sleeve 2. An oblong through hole 9 is opened in the direction, the bolt 6 is inserted into the oblong through hole 9, and the nut 7 is embedded in the support platform 1. The shaft sleeve 2 is locked by tightening the bolt 6 in the nut 7. After the shaft sleeve 2 grows and causes the position of the wing plate 5 to change, it can still be fixed on the support platform 1 by the bolt 6. Before locking the output shaft, the wing plates 5 on the two sections of the shaft sleeve 2 are first misaligned, and then the tapered sleeve 3 is pushed into the shaft sleeve 2 for pre-locking, and then the shaft sleeve 2 is rotated for locking. After the wing plates 5 on the two sections are coplanar, the wing plates 5 are fixed on the support platform 1.

[0027] In this embodiment, if Figure 1 As shown, the sleeve 2 and the output shaft are made of the same material, and the hardness of the material making the tapered sleeve 3 is lower than the hardness of the material making the output shaft, so as to avoid crushing the output shaft during locking and ensure the appearance quality of the output shaft.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
