[0020] 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.

[0021] Example 1:

[0022] Please see Figure 1-4 This utility model provides a technical solution: a positioning and centering device for shaft parts in a mechanical production line, including a support base 1, with upright plates 2 installed on both sides of the upper end of the support base 1, a support block 3 provided on the upper end of the upright plate 2, a cylinder 4 installed on the outer side of the support block 3, an arc-shaped positioning seat 5 installed on the inner side of the cylinder 4 through a piston rod passing through the inner side of the support block 3, a rubber pad adhered to the inner cavity of the arc-shaped positioning seat 5, a fixing block 6 installed on the lower end of the cylinder 4, a hydraulic cylinder 7 installed on the lower end of the fixing block 6, the lower end of the hydraulic cylinder 7 being fixed to both sides of the upper end of the support base 1, and a moving rod 8 provided on the front and rear sides of the lower end of the support block 3, the lower end of the moving rod 8 passing through the front and rear sides of the inner cavity of the upright plate 2.

[0023] In this embodiment, the support seat 1 is first installed in the shaft processing area of ​​the mechanical production line using the L-shaped fixing seat 13 and bolts. Then, the shaft part that needs to be positioned is placed in the positioning groove. The cylinder 4 is started, and the cylinder 4 drives the arc-shaped positioning seat 5 to move. The arc-shaped positioning seat 5 is fixed to the shaft part by a rubber pad. The rubber pad protects the surface of the shaft part and prevents the arc-shaped positioning seat 5 from directly contacting the surface of the shaft part, thus preventing wear on the surface of the shaft part.

[0024] Example 2:

[0025] Please see Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: A push plate 9 is installed at the lower end of the moving rod 8. The push plate 9 is horizontally arranged at the lower end of the inner cavity of the upright plate 2. Guide rails 10 are provided on the front and rear sides of the inner side of the upright plate 2. Guide blocks 11 are slidably connected to the inner cavity of the guide rails 10. The outer side of the guide blocks 11 is fixed to the front and rear sides of the inner side of the push plate 9. A positioning platform 12 is provided at the center of the upper end of the support base 1. A positioning groove is opened at the upper end of the positioning platform 12. An L-shaped fixing seat 13 is installed at the lower end of the support base 1. A bolt is provided at the upper end of the L-shaped fixing seat 13, and the lower end of the bolt passes through the lower end of the L-shaped fixing seat 13. A maintenance plate is provided on the rear side of the outer side of the upright plate 2 by screws. A door is provided on both sides of the front of the support base 1 by hinges.

[0026] In this embodiment: when it is necessary to position and center shafts of different heights, the hydraulic cylinder 7 is activated. The hydraulic cylinder 7 drives the support block 3 to move through the fixed block 6. The support block 3 drives the moving rod 8 to move in the inner cavity of the vertical plate 2. At the same time, the moving rod 8 drives the guide block 11 to slide in the inner cavity of the guide rail 10 through the push plate 9, which effectively increases the stability of the moving rod 8 and the push plate 9 when they move. In addition, the moving rod 8 can smoothly adjust the height of the arc-shaped positioning seat 5 through the support block 3. It can be adjusted according to the shaft parts of different heights, which is convenient for the shaft parts to be quickly positioned and centered, and facilitates the subsequent processing of the shaft parts.

[0027] The working principle of the positioning and alignment device for shaft parts in a mechanical production line provided by this utility model is as follows:

[0028] Implementation steps for the first innovation point:

[0029] Step 1: First, install the support base 1 in the shaft processing area of ​​the mechanical production line using the L-shaped fixing base 13 and bolts, and then place the shaft parts that need to be positioned in the positioning groove;

[0030] Step 2: Start cylinder 4. Cylinder 4 drives the arc-shaped positioning seat 5 to move. The arc-shaped positioning seat 5 is fixed to the shaft parts by rubber pads.

[0031] Step 3: By setting the rubber pad, the surface of the shaft parts can be protected, preventing the arc-shaped positioning seat 5 from directly contacting the surface of the shaft parts and causing wear on the surface of the shaft parts.

[0032] Implementation steps for the second innovation point:

[0033] Step 1: When it is necessary to position and center shafts of different heights, start the hydraulic cylinder 7. The hydraulic cylinder 7 drives the support block 3 to move through the fixed block 6. The support block 3 drives the moving rod 8 to move in the inner cavity of the vertical plate 2. At the same time, the moving rod 8 drives the guide block 11 to slide in the inner cavity of the guide rail 10 through the push plate 9, which effectively increases the stability of the moving rod 8 and the push plate 9 when they move.

[0034] Step 2: Additionally, the moving rod 8 can smoothly adjust the height of the arc-shaped positioning seat 5 by adjusting the support block 3. This can be adjusted according to shaft parts of different heights, making it easier to quickly position and center the shaft parts, and facilitating subsequent processing of the shaft parts.
