Abstract
An in-die tapping machine with an excessive torque failure device consists of a T-shaped plate, a lower plate, a middle plate, an upper plate, a moving block, a drive shaft, a drive gear, a spindle, a driven wheel, a screw tap spindle and a screw tap locking mechanism, wherein an inner connecting hole is formed in the top end of the screw tap spindle, and the torque failure device connected with the drive shaft and the screw tap spindle is arranged at the top end of the inner connecting hole. Due to the fact that the in-die tapping machine is provided with the torque failure device, when the hardness of a tapped material is higher than the tapping hardness of a screw tap, the in-die tapping machine has the advantages of being capable of safely retreating to ensure the safety of the device and the material. Accordingly, the safer and more efficient usage requirement of the in-die tapping machine in the using process is met.
Description
Technical field
A kind of mould tapping machine with crossing moment of torsion disabling device.
Background technology
Mould tapping machine is the common equipment of tapping in machining, has tapping efficiency high, the measured feature of matter, and adding industry at machine has extensively and use frequently.
Although mould tapping machine in the past can complete the tapping operation under conventional sense preferably, but, when being exceeded screw tap by the material hardness of tapping and can attacking hardness, because it does not have preventing function and preventing structure, screw tap is often caused to rupture, even the problem such as device damage, mould tapping machine can not be met, run into and attacked material hardness and exceed screw tap when can attack hardness, can Safe withdrawing, ensure the application target of equipment and material safety.
The object of the invention is, by a kind of setting of crossing moment of torsion disabling device on screw tap main shaft, make it have when attacked material hardness exceed screw tap can attack hardness time, cross moment of torsion disabling device to make to depart from power voluntarily with the screw tap main shaft of screw tap retaining mechanism, to ensure screw tap, even equipment is not damaged.
Summary of the invention
The present invention is made up of T plate, lower plate, middle plate, upper plate, movable block, power transmission shaft, travelling gear, main shaft, driven pulley, screw tap main shaft and screw tap retaining mechanism, screw tap main shaft top is provided with connection endoporus, connects the moment of torsion disabling device being provided with connection for transmission axle and screw tap main shaft in endoporus.
Moment of torsion disabling device is made up of ball, frictional force adjustment ring and annular retaining groove, annular retaining groove is arranged on screw tap main shaft top and connects inside endoporus, be provided with in retention groove and step up ball, connect endoporus hole wall and be provided with distortion groove, outside is provided with ball frictional force adjustment ring.
The course of work of the present invention is as follows: first, the coefficient of friction of moment of torsion disabling device is adjusted to operation screw tap and can attack the friction valve of hardness lower than upper limit hardness.When invention normal operation, run into and attacked material hardness and exceed operation screw tap when can attack hardness higher limit, moment of torsion disabling device can present slipping state at once, makes screw tap main shaft depart from power, effectively to ensure that operation screw tap can not twist off, the even appearance of damage equipment phenomenon.
The present invention is owing to being provided with moment of torsion disabling device, so, when run into attacked material hardness exceed screw tap can attack hardness time, under the effect of moment of torsion disabling device, the present invention has can Safe withdrawing, to ensure the feature of the safety of equipment and material, thus meets in the use procedure of mould tapping machine, safer, more efficient instructions for use.
