[0002] At present, in the field of automotive lighting, ordinary workpieces can be processed by clamping with a three-axis machine tool, and the three workpiece reference surfaces can be aligned during clamping. However, there are also some workpieces with special shapes, such as Figure 1 The special-shaped workpiece shown in the figure cannot be clamped during processing of the area to be processed because the side and bottom of the workpiece are not perpendicular to each other, so it is impossible to align the three workpiece reference surfaces. Therefore, it can only be processed by a five-axis machine tool. The cost of using a five-axis machine tool is significantly higher, and it also increases the technical and operational difficulties. It is not conducive to mass production and processing of the same special-shaped workpieces, resulting in a lack of efficiency improvement. When replacing special-shaped workpieces with different angles, the adjustment programming and operation time is long, which is more labor-intensive and particularly troublesome. Utility Model Content

[0007] A locking screw is also installed on one side of the base body. Rotating the first rotating shaft can drive the driving gear to rotate, and then drive the driven support block to rotate to drive the workbench to turn and change the inclination of the table surface. The locking screw can limit and lock the driven support block.

[0008] Furthermore, the lower half of the driven support block is formed as a semicircular gear, and the semicircular gear is meshed with the driving gear.

[0009] Furthermore, the radius of the driving gear is smaller than the radius of the semicircular gear.

[0010] Furthermore, both side ends of the driven support block are formed with limit plates, and the outer end surface of the limit plate is in close contact with the inner end surface of the assembly groove.

[0011] Furthermore, one end of the first rotating shaft extends out of the outer end surface of the base body, and a knob is provided on the extended end of the first rotating shaft.

[0012] Furthermore, one end face of the second rotating shaft is flush with the outer end face of the base body, an indicator needle is arranged on the flush end face of the second rotating shaft, and a graduated angle ruler is also arranged on the outer end face of the base body close to the indicator needle.

[0018] 4. The utility model uses the design of the indicator needle on the end face of the second rotating shaft and the scale ruler on the outer end face of the base body to visually observe whether the second rotating shaft is offset, thereby ensuring that the inclination of the workbench is in a constant state, avoiding the offset problem after long-term work, and facilitating timely inspection and compensation.

DETAILED DESCRIPTION

[0025] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0026] In the prior art, reference Figure 1 As shown, there is a special-shaped workpiece 7. When processing the area to be processed, the side surface of the workpiece is not perpendicular to the bottom surface, so the three-axis machine tool cannot be clamped during processing, and the three workpiece reference surfaces cannot be aligned. Therefore, only a five-axis machine tool can be used for angle processing.

[0027] Therefore, if Figure 2-5 As shown, in this embodiment, a workbench for assisting in processing the swing angle is provided, which is mainly composed of a base body 1, a driving gear 2, a driven support block 3, a workbench 4, a fixing screw 5, a locking screw 6 and other components.

[0028] A mounting groove 10 is provided downwardly at the center of the top of the base body 1, the driving gear 2 is rotatably mounted at the bottom of the mounting groove 10, and the driven support block 3 is rotatably mounted at the upper part of the mounting groove 10 and exposed. A first rotating shaft 21 is fixedly provided at the center of the driving gear 2, through which the driving gear 2 is rotatably mounted, and one end of the first rotating shaft 21 extends out of the outer end surface of the base body 1, and a knob 22 is fixedly provided at the extended end of the first rotating shaft 21 to facilitate the adjustment of the rotation of the first rotating shaft 21. A second rotating shaft 31 is fixedly provided at the center of the driven support block 3, through which the driven support block 3 is rotatably mounted, and the second rotating shaft 31 is thicker than the first rotating shaft 21, which is conducive to the support of the workbench 4, and the workbench 4 is mounted on the top of the driven support block 3 by two fixing screws 5, and is used to place the special-shaped workpiece 7.

[0029] In order to form a linkage between the driven support block 3 and the driving gear 2, a semicircular gear 30 is formed at the lower half of the driven support block 3, and the semicircular gear 30 is meshed with the driving gear 2. The design of the driven support block 3 can better support the workbench 4 and maintain stability during rotation. In order to facilitate labor-saving adjustment, the radius of the driving gear 2 is smaller than the radius of the semicircular gear 30.

[0030] So, reference Figure 4 After the irregular workpiece 7 is placed and positioned on the surface of the workbench 4, the adjusting knob 22 can be manually operated to control the first rotating shaft 21 and the driving gear 2 to rotate, and then the driven support block 3 is driven to rotate to drive the workbench 4 to turn and change the inclination of the table surface. Taking the first irregular workpiece 7 as a standard, the irregular workpiece 7 is adjusted to Figure 5 Of course, a locking screw 6 is also installed on one side of the base body 1. After being adjusted into place, the driven support block 3 is locked and fixed by the locking screw 6. Subsequently, the same special-shaped workpieces 7 can be mass-produced and processed, which reduces the difficulty of operation and adjustment and improves the production and processing efficiency. Moreover, when replacing special-shaped workpieces of different angles, the adjustment and adaptation can be completed quickly, and the operation is extremely convenient and fast.

[0031] In order to prevent the semicircular gear 30 from rubbing against the edge of the base body 1, limit plates 32 are formed on both side ends of the driven support block 3, and the outer end surfaces of the limit plates 32 on both sides are closely attached to the inner end surface of the assembly groove 10. When the driven support block 3 rotates, on the one hand, it can protect the semicircular gear 30, and on the other hand, it can form a lateral limit to prevent the workbench 4 from shaking.

[0032] In order to facilitate timely inspection of the deflection of the workbench 4, one end face of the second rotating shaft 31 is flush with the outer end face of the base body 1, and an indicator needle 310 is sprayed or adhered on the flush end face of the second rotating shaft 31, and a scale angle ruler 100 is also engraved or sprayed on the outer end face of the base body 1 near the indicator needle 310. In this way, when the standard parts are adjusted in place for the first time, the angle scale indicated by the indicator needle 310 is recorded, and it is convenient to visually observe whether the second rotating shaft 31 is deflected later, especially after long-term work, the workbench 4 may deflect, so it is convenient to monitor and check the compensation in time at any time to ensure that the inclination of the workbench 4 can be kept in a constant state.
