The first drill bit 312 is fixed to the output shaft of the first drilling drive 311, and the first drill bit 312 is used to drill a hole at the first through hole 91 at the top of the lamp housing 9. In this embodiment, the first drilling assembly 31 has two first drill bits 312, so that the first drilling assembly 31 can drill two first through holes 91 on the lamp housing 9 at the same time.

[0045] The tapping assembly 32 is located at one side of the first drilling assembly 31. In the processing direction, the first drilling assembly 31 is located at the front side of the tapping assembly 32.

[0055] The steering assembly 71 is located as a whole on the side of the first conveying module 63 facing the second drilling mechanism 4. The steering assembly 71 includes a rotating cylinder 711 and a lifting cylinder 712 connected to the rotating cylinder 711. The rotating cylinder 711 is a 90-degree rotating cylinder, which is fixed to the outer bottom of the workbench 1 through a bracket, and its output shaft passes through the bottom of the workbench 1. The lifting cylinder 712 is vertically arranged on the top of the rotating cylinder 711, and the output shaft of the lifting cylinder 712 is fixedly installed with a steering fixing plate 713, and a plurality of steering rods 714 for inserting into the first plug hole 22 at the bottom of the positioning seat 2 are fixed on the steering fixing plate 713. The placement groove 611 on the sliding seat 61 has a through hole that penetrates the sliding seat 61, and the through hole is used for the steering rod 714 to pass through and plug and match with the positioning seat 2.

[0056] When the lamp housing 9 completes drilling and tapping at the first drilling station and moves to the end of the first conveying module 63, the steering assembly 71 and the positioning seat 2 correspond in height direction, and the lifting cylinder 712 is started to insert the steering rod 714 into the first insertion hole 22; the clamping mechanism 62 releases the pressure on the lamp housing 9, and the positioning seat 2 is lifted again so that the positioning seat 2 is located at the top of the clamping rod 622, and finally the positioning seat 2 is rotated 90° by rotating the cylinder 711 to facilitate the second drilling.

[0057] The second conveying module 72 includes a first conveying frame 721, a horizontal module 722, a vertical module 723 and a transfer seat 724.

The transfer rod 7241 is slidable by a cylinder, and is used to be plugged and matched with the second socket 23 on the side wall of the positioning seat 2.

[0058] When the positioning seat 2 drives the lamp housing 9 to turn, the transfer seat 724 moves to a height corresponding to the positioning seat 2, and the transfer rod 7241 and the positioning seat 2 are plugged in and matched by the cylinder, and then the positioning seat 2 and the steering rod 714 are released through the second conveying module 72, and the positioning seat 2 is horizontally conveyed to the second drilling station.

[0059] Reference Figure 6 and Fig. 9The second drilling station is provided with a positioning assembly 73 for arranging the positioning seat 2 and a second spray pipe 74 for cooling and removing chips. The positioning assembly 73 includes a positioning frame 731, a positioning plate 732 rotatably mounted on the positioning frame 731, and a clamping member 733 corresponding to the positioning plate 732. The positioning plate 732 is arranged correspondingly to the second drill bit 412. The side wall of the positioning plate 732 is installed with a rotating driving source for driving the positioning plate 732 to rotate. The rotating driving source can be a rotating motor or a rotating cylinder, and its output shaft and the rotating shaft of the positioning plate 732 are driven by gears. Among them, the positioning frame also has a clearance groove 7311 for the rotational arrangement of the positioning plate 732. The positioning plate 732 is rotatably arranged in the clearance groove 7311, so that the positioning seat 2 rotates ninety degrees to ensure the verticality of the axis of the second through hole 92 on the lamp housing 9.

[0060] The top of the positioning plate 732 has a positioning rod 7321 that is plugged into the first plug hole 22. An elastic plunger 7322 is installed at the end of the positioning rod 7321. The elastic plunger 7322 is a ball head spring in the prior art, and the inner side wall of the first plug hole 22 has a locking groove (not marked in the figure) that cooperates with the plunger head of the elastic plunger 7322, so as to reduce the probability of the positioning seat 2 falling off the positioning plate 732 after rotation.

[0061] The pressing member 733 corresponds to the rotated positioning plate 732. The pressing member 733 is driven by a push cylinder, and moves horizontally toward the lamp housing 9. The cooperation between the positioning plate 732 and the pressing member 733 improves the stability of the lamp housing 9 during the second drilling.

[0062] The second spray pipe 74 is installed at the four corners of the positioning frame, and the output end of the second spray pipe 74 faces the end of the second drill bit 412. In this embodiment, the second drilling station has two second spray pipes 74, and the second spray pipe 74 is used in the same way as the first spray pipe 65.

The placement plate 84 is used to place the lamp housing 9 that has completed the second drilling. A placement seat 85 that cooperates with the positioning seat 2 is slidably installed on the top of the placement plate 84. The placement seat 85 is slidable by the motor screw, and the sliding direction is perpendicular to the processing direction. After the second drilling is completed, the operator manually removes the positioning seat 2 from the positioning plate 732 and places it on the top of the placement plate 84. The placement direction is the same as the posture of the second drilling station. While taking it, the operator observes whether the two through holes of the lamp housing 9 that have completed the drilling are qualified.

[0066] The third conveying module 82 has the same structure as the second conveying module 72, and the third conveying module 82 only includes a vertical module. The clamping seat 89 is fixed on the vertical module 723 of the third conveying module 82, and has a clamping plate for clamping the positioning seat 2, and the clamping plate is driven by the clamping cylinder 621.
