The two processing mechanisms can move closer or further apart through the cooperation of the slide rails and lead screw motors, realizing processing in the left-right direction (Y-axis direction) of the entire machine tool. While achieving synchronous processing, the two processing mechanisms can move closer to each other, which increases the processing area compared to products in the prior art, thus optimizing the deficiency that dual processing tools cannot process areas that are separated. A grating for detecting motion dimensions is set on the side of the first slide rail, the second slide rail, and the third slide rail to improve motion accuracy and processing accuracy.

[0027] As one embodiment of this application, please refer to Figures 1-7As shown, in this embodiment, the first processing mechanism 9 includes a first sliding saddle 24, and the second processing mechanism 10 includes a second sliding saddle 25. The adjacent ends of the first sliding saddle 24 and the second sliding saddle 25 are respectively provided with mounting grooves 26.

[0028] In the above embodiment, the first slide saddle 24 and the second slide saddle 25 move on the slide rail under the drive of two lead screw motors. The first slide block 30 and the second slide block 31 on the first slide saddle 24 and the second slide block 25 are arranged adjacent to each other, and the adjacent surfaces of the two slide blocks are planes. When the two slide blocks are in the final state, the adjacent surfaces of the two slide blocks are in contact. At this time, the distance between the two processing parts 32 is the smallest, which can reach 400mm, and the processing area of ​​the processing machine tool is the largest, and the unprocessable area is the smallest, which effectively improves the processing efficiency and optimizes the shortcomings of the prior art where the processing area residue is too large.

The output end of the parallel hydraulic cylinder 35 is connected to the first / second slide block. The parallel hydraulic cylinder can keep the movement of the two slide blocks (Z-axis direction) parallel and can lift the slide blocks to prevent them from falling and affecting the machining accuracy.

[0030] As one embodiment of this application, please refer to Figures 1-8As shown, in this embodiment, the first / second slide block is connected to the machining section 32 by a plurality of spindle screws 36.

The first adjustment block 38 is clamped on both sides of the machining section 32. The second adjustment block 39 is secured to the outside of the first adjustment block 38 by the locking screw 41. The adjustment screw 40 passes through the second adjustment block 39 and the first adjustment block 38 sequentially from the outer wall of the second adjustment block 39 inward. The protruding end of the adjustment screw 40 abuts against the side wall of the machining section 32. In the above, the contact end between the second adjusting block 39 and the first adjusting block 38 is provided with a groove for accommodating the first adjusting block 38, which can form a better abutment effect on the first adjusting block 38.

[0031] In this embodiment, the machining trajectories of the two machining parts 32 are adjusted to be at the same level through the cooperation of two adjusting blocks and adjusting screws 40, so that the two machining parts 32 are machined at the same level (X-axis) during the machining process. The adjustment process is as follows: the first adjusting block 38 is abutted against the outer ends of the machining part 32, and the second adjusting block 39 is used to abut against the first adjusting block 38. The first adjusting block 38 is accommodated in one end of the second adjusting block 39. The second adjusting block 39 is fixed to the slide block by locking screws. The front and rear clearance between the spindle of the machining part 32 and the slide block is adjusted by adjusting screws (the end of the adjusting screw abuts against the outer side of the spindle of the machining part 32, so that the spindles of the two machining parts 32 move back and forth to ensure that the centers of the spindles of the two machining parts are at the same level), so that the X-axis machining of the two machining parts 32 is at the same level.

[0032] As another embodiment of the above implementation method, please refer to Figures 1-7 as well as Figure 9 As shown, each of the first and second slide blocks is provided with a third adjusting block 42 and at least three fourth adjusting blocks 43. The third adjusting block 42 includes a fitting block 44, the end face of the fitting block 44 near the slide block is shaped to match the outer surface of the slide block, and an adjusting screw is provided on the fitting block 44. An actuating rod 45 is connected to the end face of the fitting block 44 near the slide block, and the actuating rod 45 passes through the slide block and acts on the side wall of the processing part 32. The fourth adjusting blocks 43 are distributed on the slide block away from the end of the third adjusting block 42, and the end of the fourth adjusting block 43 passes through the slide block and abuts against the side wall of the processing part 32. An adjusting screw is provided on the fourth adjusting block 43.

[0033] In this embodiment, the two adjusting blocks first abut against the outer wall of the spindle of the machining section 32, and then tighten the adjusting blocks by adjusting screws to make the machining of the spindles of the two machining sections 32 at the same level. Then, the adjusting blocks are retracted by locking screws to complete the assembly. During this process, the mating block 44 of the third adjusting block 42 can fit well with the outer side of the slide, thereby improving the connection stability between the adjusting block and the slide and the convenience of adjustment.

[0034] It should be noted that the processing unit 32 involved in this application is a product in the prior art, and will not be described in detail here. The processing unit 32 can realize processing in the circumferential direction. Through the combination of the above embodiments, processing in the multi-axis direction can be realized. The two processing units 32 are arranged adjacently and the processing area is increased by the cooperation of the slide rail and the lead screw. The two processing units 32 can be processed synchronously, which not only reduces the processing residue area, but also effectively improves the processing efficiency. The adjustment mechanism (i.e., precision adjustment) can adjust the synchronous processing precision of the two processing units 32, which effectively improves the processing quality of the mold.
