Abstract

The utility model discloses a tapping synchronizer on automatic tapping machine, which comprises a main shaft, a shaft sleeve, a tapping clamp and a screw tap arranged on the tapping clamp, wherein the main shaft is arranged in the shaft sleeve, external threads are arranged on the main shaft, a sleeve is sleeved on the main shaft, internal threads which are matched with the pitch of external threads of the main shaft are arranged in the sleeve, the sleeve is fixed in the shaft sleeve, when a belt wheel drives the main shaft to rotate in a high speed through the main shaft, the main shaft moves forward along the external threads on the main shaft through matching with the inner threads of the sleeve, since the limitation of the pitch, the pitch of the threads is matched with the tapping pitch on the screw tap, the forward moving speed of the tapping is uniform and stably forward, thereby completing the high quality tapping operation, improving the producing efficiency and improving the yield.

Description

Screw tap sychronisation on the automatic tapping machine

Technical field

The utility model relates to the screw tap sychronisation on the automatic tapping machine.

Background technology

At present, automatic tapping machine generally adopts driven by motor feed shaft and screw tap to carry out the tapping operation, screw tap is set directly on the motor, and such structure normally bearing block is provided with buffer unit, in order to guarantee the stable forward and at the uniform velocity straight line of screw tap in tapping process.Still there is following defective in said structure in practical operation: occur a mao tooth easily at the tapping position, occur mashed tooth easily yet, yield rate is not high, waste material and artificial.

The utility model content

At above-mentioned defective, the purpose of this utility model is to provide the sychronisation of the screw tap on the automatic tapping machine, can reach the synchronous purpose of feeding and pitch, make tapping operate at the uniform velocity straight line, stable forward.

Above-mentioned purpose is achieved by the following technical solution:

Screw tap sychronisation on the automatic tapping machine, include main shaft, axle sleeve, tap holder, be arranged on the screw tap on the tap holder, main shaft is arranged in the axle sleeve, it is characterized in that: have external screw thread on the main shaft, be arranged with sleeve pipe on the main shaft, be provided with the internal thread that matches with main shaft external screw thread pitch in the described sleeve pipe, this sleeve pipe is fixed in the axle sleeve.

Described thread pitch is identical with screw tap pitch on the screw tap.

Also be arranged with the guiding copper sheathing on the described main shaft, be provided with rolling bearing at an end of main shaft.

Described axle sleeve is provided with the lubricating cup mouth that is used for adding machine oil.

Adopt the automatic tapping machine of said structure screw tap sychronisation, fix an interior screwed pipe cover in the axle sleeve, the external screw thread pitch on the main shaft and the internal thread pitch of pipe box match, and thread pitch is identical with screw tap pitch on the screw tap.When belt pulley rotates at a high speed by spindle drive key drive main shaft, the main shaft just external screw thread on it and pipe box screw-internal thread fit is made forward movement, because the qualification of pitch, make the advancing at the uniform velocity of screw tap, stablize forward, and then finish high-quality screw tap operation, and enhance productivity, improve yield rate.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, shown in Figure 3, screw tap sychronisation on the automatic tapping machine, include main shaft 1, axle sleeve 2, tap holder 3, be arranged on the screw tap 4 on the tap holder 3, main shaft 1 is arranged in the axle sleeve 2, the driving key 11 of main shaft 1 one ends is built in the belt pulley 5, and the other end 12 of main shaft 1 links to each other with tap holder 3, has external screw thread 12 on the main shaft 1, be arranged with the internal thread sleeve pipe 6 that matches with its external screw thread 12 pitch on the main shaft 1, thread pitch is identical with screw tap pitch on the screw tap.Internal thread sleeve pipe 6 is fixed in the axle sleeve 2.Also be arranged with guiding copper sheathing 7 on the main shaft 1, be provided with rolling bearing 8 at an end of main shaft 1, axle sleeve 2 is provided with the lubricating cup mouth 21 that is used for adding machine oil.

As shown in Figure 3, Figure 4, axle sleeve 2 is limited in the axle sleeve feeding and tightens up top power plate 9.Before the screw tap, the axle sleeve feeding tightens up top power plate 9 by cylinder 10, limited screw, near switch tapper mechanism is navigated to work station; Start power, the external screw thread pitch on internal thread pipe box 6, the main shaft 1 is identical with screw tap pitch on the screw tap 4, so the main shafts 1 in the axle sleeve 2 drive by belt pulley 5 and rotate back straight line at the uniform velocity under the qualification of internal thread pipe box 6, stable forward, finish the screw tap operation; The motor sighal replacement, main shaft 1 contrary direction withdraws from stable retreating with the speed straight line.

Claims

1, the screw tap sychronisation on the automatic tapping machine, include main shaft, axle sleeve, tap holder, be arranged on the screw tap on the tap holder, main shaft is arranged in the axle sleeve, it is characterized in that: have external screw thread on the main shaft, be arranged with sleeve pipe on the main shaft, be provided with the internal thread that matches with main shaft external screw thread pitch in the described sleeve pipe, this sleeve pipe is fixed in the axle sleeve.

2, the screw tap sychronisation on the automatic tapping machine as claimed in claim 1 is characterized in that: described thread pitch is identical with screw tap pitch on the screw tap.
