Detailed Description

The following description of the preferred embodiments of the present invention with reference to the accompanying drawings will more clearly and completely illustrate the technical solutions of the present invention.

As shown in figure 1, the automatic tapping equipment for the double female studs comprises a workbench 18, wherein an industrial personal computer 17 and a clamping table 1 are arranged on the workbench 18, a feeding mechanism and a discharging groove 16 are arranged below the clamping table 1, and tapping machines 13 are arranged on two sides of the clamping table 1.

The double-screw bolt machining fixture is characterized in that a guide groove 2 is formed in the clamping table 1, material clamping plates 3 are arranged on two side groove walls of the guide groove 2, a double-screw bolt 6 to be machined is sent into the space between the material clamping plates 3 through a feeding mechanism, so that the double-screw bolt 6 to be machined is clamped by the material clamping plates 3, a locking mechanism is arranged on the clamping table 1 and used for clamping and positioning the double-screw bolt 6 to be machined, and then internal thread machining at two ends of the double-screw bolt is achieved through the tapping machine 13. Wherein, the material clamping plate 3 is made of flexible material, which is convenient for clamping the stud to be processed and avoids damage.

As shown in fig. 2, the feeding mechanism includes a vibrating disk 4, a linear feeder 5, a feeding cylinder 7 and a feeding plate 8, the feeding plate 8 is located at the bottom of the guide groove 2, the top end of the feeding plate is V-shaped, the studs 6 to be processed are sent to the feeding plate 8 one by one through the cooperation of the vibrating disk 4 and the linear feeder 5, and then the feeding plate 8 is pushed by the feeding cylinder 7 to push the studs 6 to be processed between the clamping plates 3.

Furthermore, the tail end of the feeding plate 8 is provided with a feeding sensor for detecting whether the stud 6 to be processed is sent to the feeding plate 8 or not, and a feeding signal is sent to the feeding cylinder 7 through an industrial personal computer 17.

As shown in fig. 3, the locking mechanism includes a pushing cylinder 9 and a positioning cylinder 11 which are oppositely arranged on two sides of the guide groove 2, a piston rod of the pushing cylinder 9 is connected with a locking tongue 10, a piston rod of the positioning cylinder 11 is connected with a positioning tongue 12, the positioning tongue 12 is pushed by the positioning cylinder 11 to be inserted and positioned with the guide groove 2, and then the pushing cylinder 9 drives the locking tongue 10 to push the stud 6 to be processed on the material clamping plate 3 onto the positioning tongue 12, so as to realize clamping and positioning.

As shown in fig. 4, the outer ends of the locking tongue 10 and the positioning tongue 12 are both V-shaped, and the bottom of the outer end of the positioning tongue 12 is provided with a supporting plate, so that the clamping and positioning of the stud 6 to be processed are realized through the matching of the locking tongue 10 and the positioning tongue 12.

As can be seen from fig. 3, in the cylinder clamping process, after the positioning cylinder 11 acts to complete the inserting positioning, the material pushing cylinder 9 has a small section of suspension motion (a stage where the material clamping plate 3 is separated but the two tongues are not clamped yet) in the material pushing process, and at this time, the workpiece is prone to sliding deviation, and the centering cannot be guaranteed, so that the clamping has a deviation. At this time, if tapping is continued, the thread depth at the two ends of the stud is increased to a depth which does not meet the thread machining requirement. Therefore, in the present embodiment, a spring damper 14 (elastically connected to the positioning tongue 12) as shown in fig. 5 is added to the positioning tongue 12 of the positioning cylinder 11, so that the stud can be pre-clamped by the cooperation of the locking tongue 10 and the spring damper 15 during the floating movement, and the sliding deviation is prevented.

Further, a positioning sensor is arranged on the positioning tongue 12 and used for detecting whether the stud 6 to be machined is clamped in place or not and sending a tapping signal to the tapping machine 13 through the industrial personal computer 17.

An important ring is not ignored in the machining process, namely, chips are discharged, the depth of the machined internal thread is deeper, the machined chips are longer and are wound on the screw tap 19, even if lubricating liquid is used for washing, the chips are still attached to the screw tap 19, and the chips are more and more increased along with the increase of the machining quantity. Excessive chipping can affect the life of the tap and the thread profile. Based on this, as shown in fig. 6, in the present embodiment, a cutting blade 15 is placed at the position where the tap passes (i.e., in the machining hole of the guide groove 2), and like a lathe column, when the tap 19 is advanced and retracted, the cutting blade cuts off the slender chips, so that the chips can be washed away by the cutting fluid, and the accumulation of the large chips is prevented.

The specific embodiment of the utility model is as follows:

during stud 6 passed through vibration dish 4 motion to sharp feeder 5, on being delivered to flitch 8 by sharp feeder 5 again, when the work piece reachd the position of flitch mouth, the material loading sensor detected the signal, and the action of material loading cylinder 7 pushes away the work piece in guide way 2, because the groove both sides press from both sides flitch 3 and adopt flexible material, consequently can not fall by the jam. At the moment, the positioning cylinder 11 pushes the positioning tongue 12 to be inserted and positioned with the guide groove 2, then the pushing cylinder 9 drives the locking tongue 10 to push the workpiece onto the positioning tongue 12, and the workpiece is clamped by the two cylinders to finish clamping. After tapping is completed, the screw tap 19 withdraws, the pushing cylinder 9 and the positioning cylinder 11 reset, the clamped workpiece is released to fall into the blanking groove 16, blanking is realized, and therefore the automatic tapping process of the double-female stud is completed.
