For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood by specific circumstances.

[0031] like Figure 1-3 As shown, the present embodiment provides an automatic positioning tapping machine, including a conveying guide groove 1, a limited telescopic rod 2 is arranged at the front end of the conveying guide groove 1, the front end of the limited telescopic rod 2 extends into the conveying guide groove 1, a proximity sensor 201 electrically connected to the limited telescopic rod 2 is arranged above the limited telescopic rod 2 corresponding to the conveying guide groove 1, a push assembly 3, a vertical tapping assembly 4 and a horizontal tapping assembly 5 are arranged on the side of the conveying guide groove 1 corresponding to the downstream of the limited telescopic rod 2, the push assembly 3 includes a workpiece holder 303 and a telescopic translation platform, the workpiece holder 303 is installed on the telescopic translation platform, and a clearance opening 101 is opened on the side of the conveying guide groove 1 corresponding to the horizontal tapping assembly 5. The clearance opening 101 can prevent the conveying guide groove 1 from obstructing the horizontal tapping.

[0032] In actual use, after the workpiece is fed into the conveying guide groove 1, the proximity sensor 201 detects the workpiece and causes the limit telescopic rod 2 to extend, positioning the workpiece at the front end of the pushing assembly 3, so that the workpiece holder 303 of the pushing assembly 3 can accurately clamp the workpiece and use the telescopic translation platform to gradually position and transport the workpiece to the vertical tapping assembly 4 and the horizontal tapping assembly 5 for tapping. After the tapping process is completed, the workpiece reaches the end of the conveying guide groove 1 and is output.

[0033] The telescopic translation platform includes a telescopic component 301 extending toward the inner side of the conveying guide slot 1, an automatic translation guide rail 302 parallel to the conveying guide slot 1, and the workpiece holder 303 is installed at the front end of the telescopic component 301, and the telescopic component 301 is installed on the automatic translation guide rail 302. The telescopic translation platform can extend forward through the telescopic component 301 and use the workpiece holder 303 to clamp the workpiece on the conveying guide slot 1, and then use the automatic translation guide rail 302 to push the workpiece forward, and the operation is stable and fast.

[0034] The workpiece holder 303 is provided with a plurality of concave sleeve grooves 304 arranged equidistantly on one side corresponding to the conveying guide groove 1. The automatic translation guide rail 302 pushes the workpiece forward by a distance of the concave sleeve groove 304 each time, and then the telescopic assembly 301 extends forward to tighten the workpiece with the concave sleeve groove 304. Therefore, by providing a plurality of concave sleeve grooves 304, a plurality of workpieces can be positioned at the same time and a plurality of tapping equipment stations can be installed correspondingly, and a plurality of tapping equipment can operate at the same time, and the equipment has high working efficiency.

[0035] The vertical tapping assembly 4 and the horizontal tapping assembly 5 both include a telescopic drive 6 and a tapping tap 7, and the tapping tap 7 is installed at the front end of the telescopic drive 6. After the pushing assembly 3 pushes the workpiece along the conveying guide groove 1 to the corresponding station of the tapping assembly, the telescopic drive 6 automatically extends forward and pushes the tap into the circular hole of the workpiece that needs to be tapped, and the working efficiency is high.

[0036] The end of the conveying guide groove 1 is connected to a downwardly inclined discharge guide groove 8, and the side of the discharge guide groove 8 is connected to a translation push rod 801. The design of the discharge guide groove 8 being movable laterally enables the workpiece to switch different output channels when discharging, which is convenient for distributing and processing the workpiece.

[0037] The front ends of the vertical tapping assembly 4 and the horizontal tapping assembly 5 are both provided with protective liquid spray nozzles (not shown in the figure). Since chips will splash during tapping and the tap will heat up due to friction, spraying protective liquid on the tapping part during tapping has multiple functions such as lubrication, heat dissipation and debris absorption.

[0038] A liquid storage tank 9 is provided below the conveying guide slot 1. The surface area of ​​the liquid storage tank 9 is larger than that of the conveying guide slot 1. The liquid storage tank 9 is surrounded by protective side plates 901. A sewage outlet 902 is provided at the bottom of the liquid storage tank 9. The liquid storage tank 9 can hold the protective liquid for convenient collection and unified recycling.

[0039] The bottom of the conveying guide groove 1 is connected with a drainage channel 102, and the end of the drainage channel 102 is connected to the liquid storage tank 9. The drainage channel 102 can timely discharge the protective liquid poured into the conveying guide groove 1 to prevent the protective liquid from hindering the movement of the workpiece.

[0040] The front end of the conveying guide groove 1 is connected to the output end of the loader 10, and the height of the output end of the loader 10 is greater than the conveying guide groove 1. The loader 10 can use a commonly used turntable loader on the market, and the loader 10 is arranged at a high place so that the output workpiece can be quickly dropped to the vicinity of the proximity sensor 201 by gravity.

[0041] The telescopic translation platform, the vertical tapping assembly 4 and the horizontal tapping assembly 5 are all electrically connected to the control panel 11, and the control panel 11 is installed above the conveying guide groove 1. The control panel 11 facilitates the rapid adjustment of the conveying and tapping process of the workpiece, so as to quickly switch the specifications of the workpiece to be processed. In addition, the top-mounted control panel 11 is ergonomic, which facilitates the technicians to debug the equipment and observe the operation process of the equipment.

[0042] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
