Description

an automatic threading machine

technical field

The utility model relates to a machine for processing internal threads, in particular to an automatic tapping machine, or a tapping machine.

Background technique

After searching, the applicant found an invention application titled "Improved Automatic Tapping Machine" (publication number: 103706895A), which disclosed an automatic tapping machine, the main technical point of which was that the tapping machine passed Qigong drives the transmission connecting rod to indirectly drive the tapping rod to move up and down. The specific structure is that a column is installed on the base, a vertical frame is installed on the top of the column, and a tapping mechanism is installed on the vertical frame. The tapping mechanism includes a driving device and a tapping mechanism. Rod and driving cylinder, wherein the driving cylinder is connected with the driving device through the transmission connecting rod, and the driving device is connected with the tapping rod, so that the action of the cylinder can drive the tapping rod to move up and down. Although this kind of tapping machine can also realize drilling and tapping, according to the structure of this tapping machine, its tapping strength and stability are questionable, because the force of the cylinder is not strong enough, and it has to pass It is driven by a transmission link that has a certain angle with the tapping rod. Obviously, this kind of tapping machine is hard to say that it has strong tapping force and sufficient stability.

Contents of the invention

In view of the deficiencies in the prior art, the utility model innovatively provides an automatic tapping machine with a large and stable tapping force. The tapping machine includes a tapping head, which is characterized in that: the tapping head includes There is a bracket on which a rotating arm motor is installed, the output end of the rotating arm motor is connected to the screw drive, the screw is threaded with a connecting block, the connecting block is fixedly connected to the connecting sleeve, and the connecting sleeve A bearing is fixed inside, and the inner fixed sleeve of the bearing is provided with a spline sleeve, and the spline sleeve is provided with a spline shaft, and the spline shaft is connected to the stepper motor in transmission, and the lower end of the spline sleeve is installed with a tap.

The first bevel gear is also fixedly installed on the screw rod, and a hand wheel is also installed on the support. The hand wheel has a wheel shaft, and a second bevel gear is fixedly installed on the wheel shaft. The second bevel gear is connected to the first bevel gear. A bevel gear meshes.

According to the tapping machine provided by the utility model, it has the advantages of stable tapping, tapping strength, etc. Compared with the prior art, it has substantial characteristics and progress.

Detailed ways

As shown in Figure 1, the automatic tapping machine includes a tapping head, and the tapping head includes a bracket 1, on which a rotary arm motor 2 is installed, and the output end of the rotary arm motor 2 is driven by a screw rod 13. Connection, and screw rod 13 is threadedly connected with connection block 12, drives screw rod 13 to rotate by rotating arm motor 2, just can drive connection block 12 to move up and down; It is installed on the fixed sleeve 6, and its specific structure is that a bearing 8 is fixedly installed in the connecting sleeve 6, as shown in Figure 2, the fixed sleeve of the bearing 8 is provided with a spline sleeve 7, and the spline sleeve 7 is provided with a spline Key shaft 5, the upper end of the spline shaft 5 is connected with the stepper motor 3 installed on the bracket 1 through the adapter 4, and the screw tap 9 is fixedly connected to the lower end of the spline sleeve 7. When the rotating arm motor 2 drives the connecting block 12 and the connecting sleeve 6 to move up and down together, the screw tap 9 also moves up and down synchronously; and when the stepping motor 3 works, the spline sleeve 7 is driven to rotate through the spline 5, thereby driving the screw tap 9 to rotate Through the above structure, the up and down movement of the tap can be realized, and the self-rotation of the tap can be realized, and the rotating arm motor 2 is used as the power source, and the screw rod 13 and the connecting block 12 with the function of the screw sleeve are selected as the transmission medium, so the tap 9 It has strong strength when tapping in the vertical direction, and because of this structure, its stability can also be guaranteed.

In order to avoid that the rotating arm motor 2 cannot work and make the screw tap 9 unable to move up and down, or to strengthen the tapping force of the screw tap 9, or to better grasp the tapping details, the utility model is also fixedly installed with a first bevel gear on the screw rod 13. 10, and a hand wheel 11 is installed on the bracket 1, and the hand wheel 11 has a wheel shaft, and a second bevel gear 14 is fixedly installed on the wheel shaft, and the second bevel gear 14 meshes with the first bevel gear 10. By turning the handwheel 11, the screw rod 13 can also be driven to rotate. When the rotating arm motor 2 cannot work or when it is necessary to break through the tapping strength of the tap, it can be realized by turning the handwheel 11.
