Description
Technical field
The utility model is about a kind of processing machine, and espespecially one kind is exclusively used in cutting out in high lead ball nut inner hole
Luo Gou the rigid turnery processing of deep hole ball screws lathe equipments.
Background technique
In order to promote industry processing efficiency, the traveling platform of many CNC toolroom machines now, Duo Youke high-speed mobile
Linear motor drives.But this linear motor is other than at high price, the control of precision, need to help with can precision positioning number
Word code sensor (optical ruler, Magnetic ruler) Lai Yingyong, therefore the use of linear motor collocation digitally coded sensor, and non-optimal
High-speed mobile solution.And the driving of tradition CNC toolroom machine traveling platform, driving is mostly controlled by ball nut and screw rod
And precision positioning.But when ball nut and its lead of screw rod be not up to 2 times even 3 times, the effect of high-speed mobile is not easy to reach again.Institute
With the ball nut and screw rod of 2 times and 3 times of high leads are the mobile required key of CNC toolroom machine Developing High-speed.
Ball nut and screw rod are by being recycled the ball of actuation as medium is rolled, in order to make ball nut in screw rod
On operation it is more accurate with screw thread Zhu Gou that is smooth, being contacted in ball nut with ball, can all be hardened using heat treatment and
The process of the grinding grinding process schematic diagram as shown in Figure 1 come the dimensional accuracy and geometric accuracy that promote screw thread Zhu Gou, leads low
When 200 attrition process of ball nut of journey, grinding wheel 100 can also deep enough ball nut 200.But the specification of ball nut is drawn
To 2 times with 3 times of high lead specification when, the grinding process of screw thread Zhu Gou is that can not be reached with traditional milling apparatus, such as
The revealed grinding wheel 100 of Fig. 2 can not be with the lead of screw thread Zhu Gou because wheel shaft and 200 one end of ball nut are interfered
Attrition process is carried out to go deep into the inner hole 201 of ball nut 200 in angle.
In addition, also having manufacturer using the processing method of rigid cutting to replace grinding process, process ball nut
After part first passes through roughing and heat treatment hardening, accurate thread cutting Zhu Gou, processing side are directly come with CBN (boron nitride) lathe tool
Formula is as shown in Figures 3 and 4, one end of ball nut 10 ' is folded in the collet 20 of vehicle tooth processing machine, in addition tool apron 30 fixes one
Hilt 40,40 front end of hilt have a CBN (boron nitride) blade 50;Whereby, control tool apron 30 is mobile, by 40 front end of hilt
CBN (boron nitride) blade 50 protrudes into the inner hole 101 ' of ball nut 10 ', carries out the machining of screw thread Zhu Gou.
But whether traditional vehicle tooth processing machine or CNC vehicle tooth processing machine, hilt 40 only have rear end to be fixed on knife
The front end (containing blade 50) of seat, hilt 40 is vacant state, and to process longer ball nut, the length of hilt 40 is more
It is long, therefore the resistance points of the fixed point of hilt 40 to blade 50 are too long, are easy to generate the vibration of hilt 40 in machining, cause
The problems such as cutting surface precision is bad, decreased tool life, scale error expand.
In addition, operation is processed in the vehicle tooth of above two mode, drilling etc., carried out all in a manner of CNC, therefore in nut material
After loading on processing machine, it is necessary to the problem of taking a long time to be calibrated, otherwise having accuracy, and be to increase operation to be stranded
Difficulty and deadline.Therefore, the processing method of conventional nut material, expensive, the overall processing operation with production board
Time is longer, accuracy is not good enough, or the problems such as consuming many prover times.The shortcomings of above-mentioned known technology should try to give
To exclude.
