[0025] As Figure 1 , Figure 2 , Figure 3 and Figure 4 It is shown in conjunction with each other, a kind of special-shaped arc plate processing frock, including arc plate 1 and the support column 2 of fixed in the bottom of arc plate 1.Support column 2 is provided with multiple roots, support column 2 is provided with two roots in the present embodiment, to ensure the stable support of arc plate 1.Through the ingenious design of support column 2 structure, realized the stable fixation and flexible adjustment of arc plate 1 on boring machine platform, improve processing precision and efficiency.

[0026] Each support column 2 comprises a column body 21 and a T-shaped head 22 mounted at the bottom of the column body 21. The design of the T-shaped head 22 enables it to be easily slid into the groove 3 of the boring machine processing platform, thereby achieving the preliminary positioning of the arc-shaped plate 1 on the platform. A locking structure is provided between the column body 21 and the T-shaped head 22, which clamps the groove 3 of the processing platform by driving the lifting of the T-shaped head 22, thereby ensuring the stability of the arc-shaped plate 1 during processing.

[0027] In one specific embodiment of the locking structure, a bolt column 41 is provided at the bottom of the column body 21, and a threaded hole is provided on the T-shaped head 22 to cooperate with the bolt column 41. By rotating the bolt column 41, the lifting of the T-shaped head 22 is achieved, thereby achieving the clamping effect.

[0028] In order to facilitate operation, there are various options for the fixation of the bolt column 41. One is to directly fix the bolt column 41 at the bottom of the column body 21, and to rotate the entire column body 21 to achieve the rotation of the bolt column 41; the other is to rotatably mount the bolt column 41 at the bottom of the column body 21, and to directly rotate the bolt column 41 by using a wrench or the like.

[0029] In the first fixation mode of the bolt column 41, the bolt column 41 can be welded to the bottom of the column body 21, and in another optimized structure in the present embodiment, the bolt column 41 can be detachably fixed to the bottom of the column body 21. The specific structure is that a through hole is provided in the center of the column body 21, and a stepped hole is provided at the bottom of the through hole. A clamping groove is provided on the stepped surface of the stepped hole, the bolt column 41 passes through the stepped hole from top to bottom, and the bolt head 411 at the top of the bolt column 41 is clamped into the clamping groove, thereby achieving stable installation of the bolt column 41. During installation, the bolt column 41 is inserted into the through hole from the top of the column body 21, and then it is continuously inserted downward until the bolt head 411 is clamped into the clamping groove; by the limitation of the clamping groove, when the column body 21 is rotated, the bolt column 41 also rotates. This design not only improves the stability of the tooling, but also facilitates the replacement and maintenance of the bolt column 41.

[0030] The structure of rotatably mounting the bolt column 41 at the bottom of the column body 21 does not provide a clamping groove on the stepped surface of the stepped hole, so that the bolt column 41 can be freely rotated, and the bolt head 411 is of an internal hexagonal structure, an internal hexagonal wrench is inserted from the top of the through hole, and then the bolt head 411 is rotated to achieve the rotation of the bolt column 41, thereby driving the lifting of the T-shaped head 22.

[0031] In addition, an adjusting cylinder 23 is also provided between the T-shaped head 22 and the column body 21, and the bolt column 41 passes through the adjusting cylinder 23 to achieve more precise height adjustment. The adjusting cylinder 23 is supported on the boring machine processing platform, and the replacement of the adjusting cylinder 23 can be achieved according to the fixed height.

[0032] The arc-shaped plate 1 is fixedly installed on the top of the column 21. The arc-shaped plate 1 and the column 21 can be fixedly connected by positioning bolts. In the embodiment, in order to realize the stable connection between the arc-shaped plate 1 and the column 21, the top of the column 21 is provided with a mounting column 211, and the bottom of the arc-shaped plate 1 is provided with a mounting hole. The mounting column 211 is inserted into the mounting hole, and the mounting column 211 and the mounting hole are provided with threads matched with each other.

The sliding sleeve 52 and the lower column 213 are further provided with a return spring 523. Under the action of the return spring 523, the outer limiting surface 521 abuts against the positioning bead 51 and drives the positioning bead 51 to protrude into the through hole of the lower column 213 and to be clamped into the inner ring groove 54. The sliding sleeve 52 is pulled downward, and the return spring 523 is compressed. At this time, the positioning bead 51 can be taken out of the through hole of the lower column 213 under the action of the pressure. The positioning bead 51 is clamped into the outer ring groove 522. At this time, the plug column 53 can be pulled out.

[0036] When the plug column 53 is inserted into the through hole of the lower column 213 and is in place, the sliding sleeve 52 is loosened. Under the action of the return spring 523, the sliding sleeve 52 goes up and presses the positioning bead 51 to be clamped into the inner ring groove 54 of the plug column 53, so as to realize the locking of the upper column 212 and the lower column 213. When it is needed to disassemble, the sliding sleeve 52 is pulled downward, the return spring 523 is compressed, the positioning bead 51 is taken out of the inner ring groove 54, and the plug column 53 can be pulled out. Through this design, the upper column 212 and the lower column 213 can be independently rotated, so as to realize the independent lifting of the T-shaped head 22 and the independent installation of the mounting column 211 and the mounting hole, and no interference is caused.

[0037] When the top of the lower column 213 is provided with a lower support surface 214 and the bottom of the upper column 212 is provided with an upper support surface 215, the upper support surface 215 can be attached to the lower support surface 214 after the insertion column 53 is inserted into the through hole of the lower column 213, thereby achieving stable support between the upper column 212 and the lower column 213.
