Description
Technical field
The utility model relates to a kind of screw tap manufacturing technology field, specifically a kind of fluting Anti-bouncing device.
Background technique
The screw thread that processing blind hole is usually played using screw tap, constantly generates scrap during processing screw thread, so screw tap
Provided with groove chip removal, to guarantee the smoothness and precision of processing screw thread, and groove is generally divided into straight trough and helicla flute.
When processing semi-finished product screw tap helicla flute, three idler wheels are usually set and radially clamp the outer of semi-finished product screw tap
Surface can improve the grinding accuracy of slot to avoid bounce of the semi-finished product screw tap in rotary course.But when processing outer diameter is small
Screw tap, such as when two millimeters of screw tap will play the role of clamping screw tap because its outer diameter is too small it is necessary to by the outer diameter ruler of idler wheel
The very little of very little setting, too small idler wheel of outer diameter itself have the shortcomings that stability is poor, clamp stable effect so not can guarantee
Fruit.If not eliminating the influence of bounce, during being ground the helicla flute of screw tap of small outer diameter, what the precision of slot not can guarantee
Meanwhile it being also easy to happen the case where screw tap is broken off, increase enterprise and produces burden.
Utility model content
To solve the above problems, the utility model provides the following technical solutions:
A kind of fluting Anti-bouncing device, the rotary chuck including semi-finished product screw tap and the clamping semi-finished product screw tap are special
Sign is: further including cylinder and block is held on top, the cylinder is located at immediately below semi-finished product screw tap, and piston rod and the top of the cylinder are held
Block is fixedly connected, the cylinder stretch out upwards piston rod drive top hold block rising withstand the positive lower end of semi-finished product screw tap.
Further, the motor for further including the grinding wheel of double of finished product screw tap processing helicla flute and grinding wheel being driven to rotate, it is described
Grinding wheel is located above semi-finished product screw tap, and the grinding wheel is axial axial at an angle with semi-finished product screw tap.
Further, the square tail of the rotary chuck clamping semi-finished product screw tap.
Further, stock material is held as match steel in the top.
Further, the grinding wheel is diamond wheel.
The beneficial effects of the utility model are:
When processing semi-finished product screw tap, servo motor drives rotary chuck rotation to drive the rotation of semi-finished product screw tap, cylinder driving
Block rising is held on top, and top holds block and persistently withstands semi-finished product screw tap lower end, while grinding wheel transverse shifting, is ground screw tap surface of semi-finished,
Formed spiral path, realize processing helicla flute effect, top hold block play avoid semi-finished product screw tap rotate when circular runout, keep away
Exempt from the case where screw tap fractures, also improves the effect of grinding spiral groove precision.
Detailed description of the invention
A kind of Fig. 1: schematic diagram of Anti-bouncing device of slotting faced
A kind of Fig. 2: schematic diagram of the vertical view for Anti-bouncing device of slotting
Specific embodiment
The utility model is further described below in conjunction with attached drawing:
Please exhibition Fig. 1 to Fig. 2, a kind of fluting Anti-bouncing device, including semi-finished product screw tap 1 and clamping semi-finished product screw tap 1
Rotary chuck 2, it is characterised in that: further include cylinder 4 and block 3 is held on top, cylinder 4 is located at immediately below semi-finished product screw tap 1, cylinder 4
Piston rod is held block 3 with top and is fixedly connected, cylinder 4 upwards stretch out piston rod drive top hold block 3 rising withstand semi-finished product screw tap 1 just under
End.Cylinder 4 will select lesser cylinder diameter, and it is disconnected that the top of senior general's semi-finished product screw tap 1 can be spent to avoid bearing force.
It further, further include that double of finished product screw tap 1 processes the grinding wheel 5 of helicla flute and the motor 6 of the driving rotation of grinding wheel 5,
Grinding wheel 5 is located at 1 top of semi-finished product screw tap, and grinding wheel 5 is axial axial at an angle with semi-finished product screw tap 1.Adjusting its angle can be real
Now process the effect of the helicla flute of different angle.
Further, rotary chuck 2 clamps the square tail of semi-finished product screw tap 1.
Further, stock material is held as match steel in top.Match steel is also known as polyformaldehyde, has that fatigue strength is high, wearability is good, resistance to has
Solvent is good and the high advantage of self-lubricating degree.Reach be hardly damaged, long service life at the same allow semi-finished product screw tap 1 rotate
The smooth effect with the lubricant that will not be sprayed or cooling corrosion.
Further, grinding wheel 5 is diamond wheel.Diamond wheel has the function of high efficient grinding, service life longest, thermally conductive
Property very good, the advantages of can avoid workpiece burn and phenomena such as crackle, improving the quality of workpiece surface processing.It is suitble to processing outer diameter
The semi-finished product screw tap 1 of small frangibility.
Mounting base is equipped between servo motor and rotary chuck 2, mounting base is installed on the workbench；Grinding wheel 5 and motor 6 are pacified
In longitudinal mould group, longitudinal mould group is mounted on pedestal one, and the effect of longitudinal mould group is to drive to move down on grinding wheel 6 and motor 6
Dynamic, pedestal one has the sliding block one being slidably connected with arc-shaped guide rail, and longitudinal mould group can be swung along arc-shaped guide rail, has adjustment
The effect of the axial angle of the axial direction and semi-finished product of grinding wheel above grinding points, realizes the mesh of the helicla flute of grinding different angle
's.Guide rail is mounted on pedestal two, and pedestal two is mounted in lateral mould group, and lateral mould group is installed on the workbench, lateral mould group
Effect be that grinding wheel 6 and motor 6 is driven to move left and right.
Cylinder 4 is installed on a mobile station, is equipped with below mobile station and is slidably connected sliding block two with linear guide, linear guide peace
Dress is on the table.The effect of mobile station is to drive cylinder to move left and right when replacing different size of semi-finished product screw tap, is adjusted
