Description

Technical Field

[0001] The utility model belongs to the technical field of horizontal boring machines, and particularly relates to a tapping device for a horizontal boring machine. Background Technique

[0002] The tapping device for a horizontal boring machine is a device widely used in machining. It is mainly used for machining internal threads on workpieces. However, at present, many tapping devices for horizontal boring machines do not have protective components at the tapping position, which brings many adverse effects to production. First of all, the lack of protective components will cause waste to easily burst outwards. During the tapping process, the generated waste may fly out, which will not only pose a safety hazard to the surrounding operators, but also may damage nearby equipment and tools. The operator may be injured by the flying waste, especially vulnerable parts such as the eyes, seriously threatening the physical health of the operator. At the same time, the flying waste may also damage other mechanical equipment in operation, increasing the cost of equipment maintenance and replacement. To sum up, the lack of protective components at the tapping position of the tapping device for a horizontal boring machine is an urgent problem to be solved. Therefore, we have developed a tapping device for a horizontal boring machine to solve this problem. Content of the Utility Model

[0022] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a tapping device for a horizontal boring machine, including: a tapping head 1, an outer sleeve 2, a connection end 3, and a mounting rod 6. There is an outer sleeve 2 behind the tapping head 1. The rear end of the tapping head 1 is connected to a mounting rod 6. A connection end 3 is installed behind the outer sleeve 2. A flat bearing 16 is installed on the outer side behind the outer sleeve 2;

[0023] A fixing ring 17 is installed on the outer side of the flat bearing 16. The extension ring 4 is connected to the front of the fixing ring 17 through a transparent corrugated pipe 8. Four vacuum chucks 5 are installed on the right side of the extension ring 4. An air suction pipe 7 is installed in the middle on the left side of the extension ring 4.

One rear top block 11 is installed in the middle on each of the upper and lower sides of the fixing ring 17. One docking hole 12 is opened at one end of each of the two rear top blocks 11 away from the fixing ring 17. One fixing nut 13 is provided behind each of the two rear top blocks 11.

[0025] A blind hole 15 is opened on the right side of the outer sleeve 2. A fixing screw 14 is installed on the upper right side of the outer sleeve 2.

[0026] A screw hole is opened on the upper right side of the mounting rod 6. A hexagonal cylinder 18 is installed in the middle on the left side inside the outer sleeve 2.

[0027] The left end of the mounting rod 6 passes through the blind hole 15 and extends into the hexagonal cylinder 18. The position of the screw hole is symmetrical to the position of the fixing screw 14.

Then, a vacuum generator is used to evacuate the four vacuum suction cups 5 through the suction pipe 7, so that the four vacuum suction cups 5 tightly adsorb the workpiece to achieve the fixation of the extension ring 4. After the extension ring 4 is fixed, the spindle of the horizontal boring machine can drive the outer sleeve 2 to rotate through the connecting end 3, and thus drive the tapping head 1 to rotate through the mounting rod 6 to perform tapping on the workpiece. During the rotation of the outer sleeve 2, the inner side of the flat bearing 16 can be driven to rotate, so that the fixing ring 17 and the extension ring 4 will not be affected. The waste generated during the tapping process is blocked inside the transparent bellows 8, so that it can prevent the waste from bursting out and damaging personnel or other equipment. After the tapping is completed, the evacuation of the vacuum suction cups 5 is released, and the extension ring 4 is pushed backward so that the two fixing rods 10 enter the two docking holes 12, and the workpiece can be removed.

[0031] Please refer to Figure 1 and Figure 2 As the second embodiment of the present invention: Further elaborating on the first embodiment, when it is not necessary for the transparent bellows 8 to block the waste during the tapping process, the extension ring 4 can be pushed backward to drive the transparent bellows 8 to compress, and at the same time, the rear ends of the two fixing rods 10 respectively pass through the two docking holes 12, and then two fixing nuts 13 are used to connect to the rear ends of the two fixing rods 10 to complete the fixation of the extension ring 4, so that the right end of the outer sleeve 2 and the tapping head 1 are exposed. During actual use, it can be flexibly selected according to different usage scenarios, so as to improve the applicability.
