Abstract
An in-die tapping machine with a retreating device and 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 the top end of the screw tap spindle and the bottom end of the spindle are sleeved with a compression spring, and a proximity switch is arranged on one side of the top end of the spindle. 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 retreating device, the in-die tapping machine has the advantages of being capable of safely retreating to ensure the safety of a screw tap and the device under the effect of the retreating device when a tapped material is not provided with a preset tapping hole. Accordingly, the safer and more efficient using requirement of the in-die tapping machine in the using process is met.
Description
Technical field
A kind of mould tapping machine with exiting and cross 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, hardness can be attacked when being exceeded screw tap by the material hardness of tapping, or during Non-precondition tapping hole, because it does not have preventing function and preventing structure, screw tap is often caused to rupture, the even problem such as device damage, mould tapping machine can not be met, run into by the material hardness of tapping exceed screw tap can attack the material Non-precondition tapping hole of hardness or tapping time, can Safe withdrawing, ensure the instructions for use of equipment and material safety.
The object of the invention is, by one, Compress Spring is set in main shaft lower end, on main shaft top, proximity switch device is set, screw tap main shaft arranged the structural design of moment of torsion disabling device, make it have the material Non-precondition tapping hole running into tapping, or by the material hardness of tapping exceed screw tap can attack hardness time, make the screw tap main shaft with screw tap retaining mechanism can effectively exit tapping state, to ensure that screw tap is not fractureed, 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 and main shaft bottom are set with Compress Spring, and side, main shaft top is provided with proximity switch; 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 normal operation of the present invention, 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.
When invention normal operation, run into when being attacked material Non-precondition tapping hole, Compress Spring senses the resistance that screw tap main shaft and screw tap retaining mechanism run into, make main shaft and screw tap main shaft entirety up, when main shaft upper end up close to proximity switch time, the automatic powered-down of proximity switch, equipment stops operation, to ensure that operation screw tap can not be lost, and then therefore guarantee equipment can not damage.
The present invention 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;
The present invention is owing to being provided with extractor, so, when run into attacked material Non-precondition tapping hole time, under the effect of extractor, the present invention has can Safe withdrawing out of service, to ensure the feature of screw tap and device security, thus meets in the use procedure of mould tapping machine, safer, more efficient instructions for use.
