[0024] Further explanation, the outer side wall of the cylindrical tapping drill machine 7 is smooth and the outer wall shape is circular, the air cylinder 5 and the cylindrical tapping drill machine 7 are common means in the prior art, and will not be described in detail here.

[0025] As Figure 1 , Figure 2 , Figure 3 and Figure 4 , a positioning mechanism is arranged between the lifting circular plate 6 and the limiting cylinder 4; the positioning mechanism comprises a limiting pipe 8 slidingly sleeved on the inner wall of the fixed cylinder 14, the outer side wall of the cylindrical tapping drill machine 7 and the inner side wall of the limiting pipe 8 are slidingly connected, the limiting pipe 8 and the lifting circular plate 6 are connected through a spring 9, an arc-shaped positioning opening 10 is formed in the limiting cylinder 4, and the bottom of the limiting pipe 8 is fixedly installed with an arc-shaped clamping plate 11 matched with the arc-shaped positioning opening 10.

[0026] Further explanation, the positioning mechanism has the functions of accurate positioning, stable support and fixed deviation prevention, the limiting pipe 8 and the tapping drill machine are slidingly connected and the spring 9 realizes accurate positioning and stable support, buffers vibration and deviation force and guides, the arc-shaped clamping plate 11 cooperates with the arc-shaped positioning opening 10 to limit the rotation and excessive movement of the tapping drill machine, so that the tapping position is accurate, the operation is stable and the quality is reliable.

[0027] As Figure 1 , a plurality of triangular clamping grooves 12 are formed in the bottom of the arc-shaped clamping plate 11.

[0028] Further illustrate, the triangular clamping groove 12 at the bottom of the arc-shaped clamping plate 11 can better engage and fix when contacting the metal cylinder 2, increase the connection reliability between the positioning device and the metal structural member, reduce the positional deviation caused by loose connection during tapping, further guarantee the accuracy of tapping, and reduce the rate of defective products.

[0029] As shown in Figure 1 The fixed cylinder 14, the lifting circular plate 6, the cylindrical tapping drill machine 7, the limiting tube 8 and the arc-shaped positioning opening 10 are coaxially arranged.

[0030] Further illustrate, the purpose of such design is to make the tapping force be uniformly transmitted, avoid the lateral force caused by different shafts, thereby maximally reduce the shaking and deviation during tapping, improve the coaxiality and perpendicularity of tapping, and meet the high-precision tapping processing requirements.

[0031] As shown in Figure 1 The spring 9 is sleeved on the cylindrical tapping drill machine 7, and the two ends of the spring 9 are fixedly connected with the bottom of the lifting circular plate 6 and the top of the limiting tube 8 respectively.

[0032] Further illustrate, during tapping, the spring 9 can play a buffering role, absorb part of the impact force caused by the uneven surface of the metal structural member or the change of tapping resistance, protect the tapping drill machine and related parts, prolong the service life of the device, and also help maintain the stability of tapping.

[0037] The utility model can be described by the following operation mode to explain its function principle:

[0038] First, the metal cylinder 2 is placed in the limiting cylinder 4 on the concave plate 3, the outer wall of the metal cylinder 2 is in close sliding fit with the inner wall of the limiting cylinder 4, and the metal cylinder 2 is ensured to be in the appropriate initial position.

[0039] Then, the cylinder 5 installed on the top of the fixed cylinder 14 of the concave plate 3 on the fixed table 1 is started, at this time, the piston end of the cylinder 5 starts to push the lifting circular plate 6 fixedly connected thereto, so that the lifting circular plate 6 slides downward along the inner wall of the fixed cylinder 14.

[0040] Since the cylindrical tapping drill machine 7 is fixedly installed at the bottom of the lifting circular plate 6, the cylindrical tapping drill machine 7 also synchronously descends, and in the descending process, the positioning mechanism starts to work.

[0041] The limiting tube 8 sleeved on the inner wall of the fixed cylinder 14 is in sliding connection with the outer wall of the cylindrical tapping drill machine 7, and under the elastic force of the spring 9, the limiting tube 8 stably slides along the inner wall of the fixed cylinder 14 to adjust the position.

[0042] At the same time, the arc-shaped clamping plate 11 at the bottom of the limiting tube 8 is matched and clamped with the arc-shaped positioning port 10 on the limiting cylinder 4, further stabilizing the position of the cylindrical tapping drill machine 7, preventing the cylindrical tapping drill machine 7 from deviating, shaking or rotating, and ensuring the accuracy of the tapping position.

[0043] Then, after the cylindrical tapping drill machine 7 reaches the predetermined position, the tapping operation on the metal cylinder 2 is started, and according to the set parameters and process requirements, the standard screw threads are processed on the metal cylinder 2.

[0044] After the tapping is completed, the piston end of the cylinder 5 is controlled to move upward, driving the lifting circular plate 6 to rise, so that the cylindrical tapping drill machine 7 rises and separates from the metal cylinder 2.

[0045] Finally, the tapped metal cylinder 2 is carefully taken out from the limiting cylinder 4, so as to be subjected to subsequent processing, quality detection and other processes.
