Wherein, the driven sheave 206 is composed of a plurality of arc shaped special-shaped members and a plurality of handle grooves, and the arc shaped special-shaped members and the handle grooves are circumferentially arranged at intervals. Arc-shaped special-shaped member the number of handle slots is the same. Alternatively, as shown in fig. 4 to 6, the number of the arc-shaped profiled members and the handle grooves is six. The specific structure of the arc-shaped profiled member and the handle groove can be seen from the structure of the driven sheave shown in fig. 4 to 6. The number of arcuate profiled members and handle grooves on the driven sheave 206 determines the angle through which the heat exchange tube 100 rotates each time the driven sheave 206 rotates, i.e., the angle between the axes of adjacent holes when the heat exchange tube 100 is perforated. For example, when the number of arc-shaped profiled members and handle grooves on the driven sheave 206 is six, the angle between the axes of adjacent two of the drilled holes is 60 °. It should be noted that, the number of the external engaged linkage mechanism 102 with grooved wheels shown in the drawings of the present invention may be six, but in a specific implementation, the number of the arc-shaped members and the handle grooves on the driven grooved wheels 206 may be set according to the needs, so as to determine the angle between the axes of the holes drilled when the heat exchange tube 100 is perforated. The following embodiments of the present invention and the accompanying drawings will be described with reference to six arcuate profiled members on the driven sheave 206 and six handle grooves.
The external engagement linkage mechanism bracket 106 with the grooved pulley and the limiting block 104 firmly fasten the heat exchange tube 100, and accurate and continuous punching is performed by matching the drill floor 103 with the external engagement linkage mechanism 102 with the grooved pulley. In the present invention, the external engagement linkage 102 with grooved wheels is mainly used for controlling the angle of each rotation of the heat exchange tube 100 when the heat exchange tube 100 is perforated. The heat exchange tube support 101 is composed of angle steel L80x80x6 and is used for placing heat exchange tubes needing punching. The type of the bolt 205 is m8×30. The clamping groove fixes the upper part and the lower part of the external engagement linkage mechanism 102 with the grooved wheels, so as to avoid the deviation during punching. The half shaft sleeve clamping device 212 is composed of two semicircular rings, one ends of the two semicircular rings are hinged, and the other ends of the two semicircular rings are movably connected through a pin shaft, so that the operation of rapidly clamping the heat exchange tube 100 can be completed by pulling out and inserting the pin shaft.

In the invention, the external engagement linkage mechanism with the grooved wheels firmly fastens the heat exchange tube, so that the limiting block 204 only needs to meet the distance between the drill floor 103 and the end part of the heat exchange tube 100 in technical requirements.
When the heat exchange tube drilling machine is used, the handle 201 is rotated, the handle disc 202 drives the driving plate 204 to rotate, when the handle 201 is clamped into one handle groove of the driven grooved pulley 206, the rotating shaft 203 and the bearing 209 drive the driven grooved pulley 206 to precisely rotate through 60 degrees, and at the moment, the heat exchange tube can be drilled through the drilling floor 103. It should be noted that friction does not occur between the driving plate 204 and the driven sheave 206, and the heat exchange tube 100 can be ensured to rotate by 60 °. This operation is circulated until six holes of the heat exchange tube 100 are completed.
The application method of the invention comprises the following steps: the half-shaft sleeve clamping device 212 is opened, the heat exchange tube 100 needing to be punched is controlled to pass through the half-shaft sleeve 207 and then is placed in the half-shaft sleeve clamping device 212, after the end rancour of the heat exchange tube 100 is used for clamping the limiting block 204, two circular rings of the half-shaft sleeve clamping device 212 are covered and a pin shaft is inserted, the heat exchange tube 100 is clamped, after a first hole is punched through the bench drill 103, the handle 201 is rotated clockwise for about one circle, when the handle 201 is clamped in the next handle groove of the driven grooved pulley 206, the driven grooved pulley 206 is precisely rotated clockwise for 60 degrees, a second hole is punched through the bench drill 103, and the like until all six holes are punched, the half-shaft sleeve clamping device 212 is opened, the heat exchange tube 100 is taken out, and punching is completed.
It should be emphasized that the punching process of the invention can be completed by only one operator, and the external engagement linkage mechanism 102 with the grooved pulley can realize rapid clamping and disassembly, errors between holes on the same heat exchange tube 100 are not accumulated or overlapped, high-efficiency, accurate and multi-angle multi-azimuth continuous punching can be effectively realized on the premise of releasing labor force, labor optimization is realized after batch production, and the production period of various reactors in the chemical industry is greatly shortened.
Finally, it should be noted that the protection scope of the present invention is not limited to the fixed-size mechanism in the drawings, and any changes or substitutions that can be easily considered by those skilled in the art within the technical scope of the present invention should be covered in the protection scope of the present invention.
