Fig. 1-4 illustrate the utility model discloses a workpiece fixture for numerically controlled tapping machine's embodiment, refer to fig. 1-4, a workpiece fixture with the function of finely tuning numerically controlled tapping machine, including base 1, first compress tightly subassembly 2, the second compresses tightly subassembly 3 and hole detection component 4.
The base 1 comprises a bottom plate 11, a vertical column 12 and a top plate 13. The top plate 13 is erected on the bottom plate 11 through a plurality of upright posts 12 to form a hollow double-layer plate-shaped structure. A first bearing platform 131 and a second bearing platform 132 for supporting two end parts of a workpiece are respectively arranged at two ends of the top plate 13 in the length direction; the top plate 13 is further provided with a clearance hole 133 between the first bearing platform 131 and the second bearing platform 132. Here, it should be noted that: the contour of the upper parts of the first bearing platform 131 and the second bearing platform 132 is similar to the lower wall contour of two end parts of a workpiece, so that the two end parts of the workpiece are more matched with the first bearing platform 131 and the second bearing platform 132 after the workpiece is placed on the base 1; meanwhile, the main body of the workpiece is abutted against the top plate 13, and the bulge at the lower part of the main body of the workpiece passes through the avoiding hole 132 and then is positioned in the cavity formed between the bottom plate 11 and the top plate 13, so that the bulge at the lower part of the workpiece is prevented from interfering with the top plate 13.
The first pressing assembly 2 comprises a rotary clamping cylinder 21, a mounting block 22, a third screw 23, a universal ball joint 24 and a pressing block 25. The rotary clamping cylinder 21 is arranged on the top plate 13; the mounting block 22 is in a straight strip shape, and one end of the mounting block 22 is fixedly connected with a piston rod of the rotary clamping cylinder 21; two threaded holes penetrating from top to bottom are arranged in the length direction of the mounting block 22, and each threaded hole is in threaded fit with one third screw rod 23; a handle 26 convenient for an operator to rotate the third screw rod 23 is mounted at the top of each third screw rod 23, and the lower end of each third screw rod 23 is fixedly connected with a ball head 241 of one universal ball joint 24; the ball seat 242 of each universal ball joint 24 is threaded onto the compression block 25.
When the first pressing assembly 2 works, the rotary clamping cylinder 21 is connected to an external air source: first, the mounting block 22 is horizontally misaligned from the first bearing table 131 in an initial state, and a workpiece is placed on the top plate 13 by an operator or a robot so that both end portions of the workpiece are respectively engaged with the corresponding first and second bearing tables 131 and 132; then, the rotary clamping cylinder 21 drives the mounting block 22 and the pressing block 25 to synchronously rotate to the position above the first bearing platform 131 and then descend until the pressing block 25 and the first bearing platform 131 are matched to clamp one end part of a workpiece; finally, an operator can manually adjust the height or angle of the pressing block 25 according to the matching condition of the pressing block 25 and the workpiece.
The principle that the angle and the height of the pressing block 25 are adjusted by an operator is as follows: when an operator rotates one of the handles 26, the handle 26 drives the corresponding third screw rod 23 to rotate, due to the threaded fit between the third screw rod 23 and the threaded hole of the mounting block 22, the third screw rod 23 simultaneously drives one corresponding end of the pressing block 25 to descend relative to the mounting block 22 while the other handle 26 does not rotate, and the other end of the corresponding pressing block 25 is relatively static to the mounting block 22, so that the angle of the pressing block 25 changes; when the operator synchronously rotates the two handles 26, the whole pressing block 25 descends relative to the mounting block 22, and the height of the pressing block 25 can be adjusted.
It should be further noted that, since the ball head 241 may rub against the ball seat 242 during the process of adjusting the state of the pressing block 25, and the ball head 241 is simultaneously subjected to the downward pressure of the rotary clamping cylinder 21 and the upward reaction force of the workpiece when pressing the workpiece, in order to ensure that the ball head 241 is not easily damaged in long-term operation, the ball head 241 is made of a ball-milled cast iron material, and the ball-milled cast iron has the advantages of high strength and good wear resistance.
