[0002] When a workpiece needs to be turned by a lathe, a workpiece fixture and a turning fixture are required. The workpiece fixture is fixed on the turning fixture, and the workpiece fixture is used to fix the workpiece to be processed, while the turning fixture is used to connect the rotating shaft of the lathe.
[0003] At present, after the turning fixture is installed on the lathe, there is a problem of poor concentricity between the workpiece fixture and the lathe equipment, resulting in non-concentricity between the workpiece installed on the workpiece fixture and the rotating shaft of the lathe, which affects the turning quality of the workpiece.
[0004] The workpiece fixture mainly includes a positioning ring and a positioning shaft, both of which are mainly used for assembling with the workpiece to ensure the concentricity of the workpiece on the lathe. When it is found that the workpiece fixture is not concentric, in the past, the machine tool was started to rotate the workpiece fixture, and then the positioning ring and the positioning shaft were processed. At this time, the processed positioning ring and positioning shaft must be concentric with the lathe. However, for some positioning rings and positioning shafts with complex structures, they are difficult to process and it is easy to produce defective products. Summary of the Invention

The adjusting block is located between the lower substrate and the upper substrate, the lower end of the adjusting block is located in the lower rectangular long groove, and the upper end of the adjusting block is located in the upper rectangular long groove; a four-way fine adjustment mechanism is arranged at the front, rear, left, and right positions of the lower substrate and the upper substrate, and the four-way fine adjustment mechanism is adapted to drive the upper substrate to make position adjustments in the front, rear, left, and right directions of the lower substrate.
[0007] Further, the four-way fine-tuning mechanism includes four fixed seats, which are respectively arranged at the front, rear, left, and right positions of the lower substrate; four locking bolts, which are respectively screwed to the four fixed seats, and the front end of the locking bolt abuts against the upper substrate.
[0008] Further, abutting blocks are respectively arranged at the front, rear, left, and right of the upper substrate, and the abutting blocks abut against the locking bolts.
[0009] Second aspect: A method for adjusting a workpiece turning center is provided, which uses the above-mentioned turning fixture; when adjusting the front and rear positions of the workpiece, loosen the left and right locking bolts, and then adjust the front and rear positions of the upper substrate by rotating the front and rear locking bolts.

It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of this application. And in the following embodiments, each embodiment has its own emphasis. For parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
[0018] To solve the technical problem that the workpiece alignment is inconvenient during the use of the turning fixture in the lathe in the prior art, an embodiment of this application provides a turning fixture. The following will be elaborated in detail.
[0019] As shown in Figures 1 to 5 A turning fixture includes a lower substrate 3, the lower end of which is fixedly connected to the machine tool rotating shaft 1, and a lower rectangular long groove 31 is opened in the middle of the upper assembly surface; an upper substrate 4, and an upper rectangular long groove 41 is opened in the middle of the lower assembly surface thereof. A workpiece fixture 2 for clamping the workpiece to be machined is installed above the upper substrate 4; the lower rectangular long groove 31 and the upper rectangular long groove 41 have the same size, and both include a pair of long sides and a pair of short sides; the upper substrate 4 is arranged on the lower substrate 3, and the upper rectangular long groove 41 and the lower rectangular long groove 31 are in a vertically staggered structure; an adjusting block 5, the adjusting block 5 is a square structure, and the side length of the adjusting block 5 is equal to the short side length of the lower rectangular long groove 31 or the upper rectangular long groove 41. The adjusting block 5 is located between the lower substrate 3 and the upper substrate 4. The lower end of the adjusting block 5 is located in the lower rectangular long groove 31, and the upper end of the adjusting block 5 is located in the upper rectangular long groove 41; a four-way fine adjustment mechanism 6, the four-way fine adjustment mechanism 6 is arranged at the front, rear, left, and right positions of the lower substrate 3 and the upper substrate 4, and the four-way fine adjustment mechanism 6 is adapted to drive the upper substrate 4 to perform position adjustment in the front, rear, left, and right directions of the lower substrate 3.
[0020] Specifically, as an optional implementation manner in this embodiment, as shown in Figure 2 The four-way fine adjustment mechanism 6 includes four fixing seats 61, which are respectively arranged at the front, rear, left, and right positions of the lower substrate 3; four locking bolts 62, which are respectively screwed to the four fixing seats 61, and the front end of the locking bolt 62 abuts against the upper substrate 4.
[0021] Specifically, as an optional implementation manner in this embodiment, as shown in Figure 2As shown, abutting blocks 63 are respectively arranged on the front, back, left and right of the upper substrate 4, and the abutting blocks 63 are abutted against the locking bolts 62.
[0022] In this embodiment, the workpiece fixture 2 still has the previous structure, and there is no need to improve the workpiece. The workpiece fixture 2 is fixed on the upper substrate 4 and can be adjusted in four directions of front, back, left and right along with the upper substrate 4.
[0023] The working principle of the turning fixture is as follows: the upper rectangular long groove 41 of the upper substrate 4 and the lower rectangular long groove 31 of the lower substrate 3 are in a vertically staggered structure; if the upper rectangular long groove 41 is distributed left and right, then the lower rectangular long groove 31 is distributed front and back; if the upper rectangular long groove 41 is distributed front and back, the lower rectangular long groove 31 is distributed left and right.
[0024] A square space is formed at the position where the upper rectangular long groove 41 and the lower rectangular long groove 31 intersect. This square space is used to place the adjusting block 5. The lower end of the adjusting block 5 is located in the lower rectangular long groove 31, and the upper end of the adjusting block 5 is located in the upper rectangular long groove 41. Therefore, the adjusting block 5 can move in four directions of front, back, left and right. Therefore, the upper substrate 4 can be quickly adjusted in position on the lower substrate 3 by relying on the adjusting block 5. Since the workpiece fixture 2 is installed on the upper substrate 4, the position adjustment of the workpiece on the workpiece fixture 2 is thus realized.
[0025] This application provides a method for adjusting a workpiece turning center, adopting the above-mentioned turning fixture; when it is necessary to adjust the front and back positions of the workpiece, loosen the left and right locking bolts 62, and then adjust the front and back positions of the upper substrate 4 by rotating the front and back locking bolts 62. After the adjustment is completed, lock the four locking bolts 62; when adjusting the front and back positions, loosen the front locking bolt 62 and screw the rear locking bolt 62 into abut against the upper substrate 4, then the upper substrate 4 moves forward. On the contrary, the upper substrate 4 moves backward.
[0026] When it is necessary to adjust the left and right positions of the workpiece, loosen the front and back locking bolts 62, and then adjust the left and right positions of the upper substrate 4 by rotating the left and right locking bolts 62.
[0027] When adjusting the left and right positions, loosen the left locking bolt 62 and screw the right locking bolt 62 into abut against the upper substrate 4, then the upper substrate 4 moves left. On the contrary, the upper substrate 4 moves right.
