DETAILED DESCRIPTION

[0024] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0025] like Figure 1-Figure 3 As shown, a special-shaped tube assembly device for a smoking knife includes an assembly platform 1, on which a positioning component 2 and a driving component 3 for assembling the special-shaped tube are provided. The positioning component 2 is provided with an inclined positioning column 204 and two clamping blocks 202 arranged on opposite sides of the positioning column 204, and the positioning component 2 is provided with a clamping cylinder 201 for driving the two clamping blocks 202 to achieve clamping; the driving component 3 includes a driving cylinder 301 and a pressing piece 302 connected to the output end of the driving cylinder 301, and the pressing piece 302 is arranged toward the positioning column 204.

[0026] Furthermore, the special-shaped tube is a bent structure, and the plug connector is connected to the connecting end of the special-shaped tube; the positioning component 2 is arranged in the moving direction of the driving component 3, and two clamping blocks 202 are provided. The two clamping blocks 202 are slidably connected to the side walls of the clamping cylinder 201, and the positioning column 204 is fixedly arranged on the clamping cylinder 201, and the positioning column 204 and the clamping block 202 are arranged on the same side of the clamping cylinder 201, and the positioning column 204 is located between the two clamping blocks 202. The positioning column 204 and the clamping block 202 are both inclined on the positioning component 2, and the two sides are opposite. The two clamping blocks 202 always move synchronously, the special-shaped tube is sleeved on the positioning column 204, and the clamping cylinder 201 drives the clamping blocks 202 to move relative to each other. The special-shaped tube is clamped and fixed by the clamping blocks 202, thereby preventing the special-shaped tube from rotating during the assembly process and affecting the assembly accuracy. In addition, the plug connector is set on the pressing piece 302, and the pressing piece 302 is driven to move under the action of the driving cylinder 301, so that the plug connector is installed on the special-shaped tube. The entire assembly process does not require alignment and calibration of the special-shaped tube and the plug connector, which improves the assembly efficiency and ensures the assembly accuracy.

[0027] The clamping block 202 is formed with a clamping groove 2021 of an arc structure. The clamping groove 2021 is formed on the inner side of the clamping block 202 and is a semicircular structure that abuts against the special-shaped tube. Furthermore, the axial direction of the positioning column 204 is arranged parallel to the axial direction of the clamping groove 2021. Specifically, the clamping groove 2021 is arranged on the side of the clamping block 202 facing the positioning column 204, and the structure of the clamping groove 2021 is adapted to the structure of the special-shaped tube. The cross section of the clamping groove 2021 is a semicircular structure. When the clamping block 202 moves to the special-shaped tube, the groove wall of the clamping groove 2021 abuts against the outer wall of the special-shaped tube, and because the positioning column 204 is parallel to the clamping groove 2021, the clamping groove 2021 fits tightly with the special-shaped tube, so that the clamping grooves 2021 on both sides of the special-shaped tube surround the special-shaped tube and clamp the special-shaped tube, ensuring that the special-shaped tube will not rotate and improving the assembly accuracy.

[0028] A mounting seat 203 is provided on the assembly platform 1, and a mounting bevel 2031 is formed on the top of the mounting seat 203 for loading the positioning column 204, the clamping block 202 and the clamping cylinder 201, and the mounting bevel 2031 is inclined from top to bottom toward the drive component 3; at the same time, the positioning column 204 is inclined, and when the special-shaped tube is sleeved on the positioning column 204, the connecting end of the special-shaped tube is in a horizontal state. Furthermore, the positioning column 204 is inclined toward one side of the drive component 3, and the angle between the positioning column 204 and the assembly platform 1 and the angle of the bending structure of the special-shaped tube itself add up to 180°, that is, when the special-shaped tube is sleeved on the positioning column 204, the connecting end of the special-shaped tube is in a horizontal state, which ensures the accuracy of the connection between the special-shaped tube and the plug connector during assembly.

[0029] The pressing member 302 is arranged to move toward the positioning assembly 2 . Furthermore, the positioning assembly 2 is arranged in the moving direction of the pressing member 302 , and the positioning assembly 2 is located at the end of the pressing member 302 .

[0030] A positioning groove 3021 is formed at the end of the pressing piece 302, and the positioning groove 3021 is arranged toward the positioning component 2. Furthermore, the positioning groove 3021 is arranged at one end of the pressing piece 302 toward the positioning component 2, and the bottom width of the positioning groove 3021 is smaller than the top width of the positioning groove 3021. When the plug connector is placed in the positioning groove 3021, the stability of the plug connector can be guaranteed, and the plug connector will not shake during the movement of the pressing piece 302, thereby ensuring the accuracy of the connection between the plug connector and the special-shaped tube.

[0031] The center line of the positioning groove 3021 and the axis of the positioning column 204 are always located on the same plane. When the plug connector is placed in the positioning groove 3021 and the special-shaped tube is sleeved on the positioning column 204, the connecting end of the special-shaped tube and the plug connector are located on the same axis, so that the plug connector and the special-shaped tube do not need to be aligned or calibrated, and the assembly of the plug connector and the special-shaped tube can be achieved, thereby improving the assembly efficiency and ensuring the assembly quality.

[0032] A mounting platform 303 is provided on the assembly platform 1 , and a driving cylinder 301 is disposed on the mounting platform 303 . The driving cylinder 301 is fixed on the mounting platform 303 toward the direction of the positioning assembly 2 .
