Illustrate the use process of the present invention below in conjunction with the accompanying drawings：
Embodiment one：Pretension is applied to plane milling grinder part 11
As shown in Figure 1, 2, in the present embodiment, mechanical prestress application component and plane milling grinder part prestressing force is selected to protect
It holds component to be used cooperatively, wherein digital display type tensiometer or mechanical tensiometer can be selected in tensiometer 7, selects in the present embodiment
For digital display type tensiometer.
First, it is adjusted according to the spacing of length dimension pair the first pedestal 13 of plane milling grinder part 11 and the second pedestal 14
It is whole, by plane milling grinder part 11 be placed into the first plane milling mill workpiece assembling seat 16 and the second plane milling mill workpiece assembling seat 17 it
Between after, then screw the spacing locking nut 20 on adjusting screw 15, keep the spacing of the first pedestal 13 and the second pedestal 14 locked.
First mounting plane milling work piece nut 19, and screwed, then mounting plane milling workpiece nut 18,
But it is adjusted to relaxation state, then tensiometer 7 and plane milling grinder part 11 are fixed together using switching nut 8.
It before applying pretension, returns to zero first to tensiometer 7, starts to apply pretension, spanner can be selected to drive manually
Dynamic worm screw 2 rotates, or is rotated come electric drive worm screw 2 using external motor, by the rotation of worm screw 2, drives worm gear 3 first
Rotation, and then shaft 5 is driven to rotate, then rotated by the rotation indirect belt moving gear 4 of shaft 5, to be further driven to rack 6
Linear movement, the pretension that plane milling grinder part 11 is completed eventually by the linear movement of rack 6 applies, while passing through tensiometer
7 read value of thrust.
After the application of pretension reaches setting value, stop continuing to for pretension first, then will be in and loosen
The plane milling grinder part stop nut 18 of state screws, and the pretension applied at this time is maintained in plane milling grinder part 11.
Switching nut 8 is disconnected first, so that tensiometer 7 is disengaged with plane milling grinder part 11 and is connected, then unloads for connecting
The connected pinboard 23 of first pedestal 13 and substrate 1, finally gets off mechanical prestress application component integral demounting.
The plane milling grinder part prestressing force removed holding component is placed to lathe together with the plane milling grinder part 11 in it
Working position, start lathe, Milling Machining carried out to plane milling grinder part 11 by lathe or mill is processed, until process finishing,
It waits for that workpiece temperature is cooled to room temperature, keeps component together with 11 slave of plane milling grinder part in it plane milling grinder part prestressing force
It is removed on bed, then unclamps plane milling grinder part stop nut 18, the unloading of pretension is realized, finally by plane milling grinder part 11
It unloads, the pre-stressed machining of plane milling grinder part 11 terminates.
Embodiment two：External disc vehicle grinder part 29 applies pretension
As seen in figures 3-5, in the present embodiment, fluid pressure type prestress application component and periphery vehicle grinder part is selected to answer in advance
It tries hard to keep and holds component and be used cooperatively.
First, the spacing of the first pedestal 13 and the second pedestal 14 is adjusted, is made between the two away from more than periphery vehicle mill
The length dimension of workpiece 29；By leading 34 endoporus of the second switching sleeve of precession in 29 one end of periphery vehicle grinder part, then gradually contracting
The spacing of 13 and second pedestal 14 of small first pedestal makes 29 other end of periphery vehicle grinder part gradually pass through the first switching sleeve 33
Endoporus, and be pierced by from 33 other side of the first switching sleeve, periphery vehicle is ground by workpiece by second level minor thread hole later
Nut 32 is installed on periphery vehicle grinder part 29, and periphery vehicle grinder part stop nut 32 keeps relaxation state, finally again
The spacing locking nut 20 on adjusting screw 15 is screwed, keeps the spacing of the first pedestal 13 and the second pedestal 14 locked.
Positioning support base 28 is unclamped, hydraulic elongator 27 and periphery vehicle grinder part 29 are threaded togather, then
Hydraulic elongator 27 is fixed on substrate 1 by positioning support base 28, finally by pipeline by the fuel feeding of hydraulic elongator 27
Hole is connected with external high-pressure oil pump, is completed at the same time the installation of pressure gauge 40.
It before applying pretension, returns to zero first to pressure gauge 40, starts to apply pretension, start external high pressure oil first
Pump, and then hydraulic elongator 27 is driven to act, by hydraulic elongator 27, directly externally disc vehicle grinder part 29 applies pretension.
After the pressure value of pressure gauge 40 reaches setting value, stop the work of high-pressure oil pump first, then will be in and loosen
The periphery vehicle grinder part stop nut 32 of state is tightened on by its first order major thread hole on the first switching sleeve 33, at this time
The pretension of application is maintained in periphery vehicle grinder part 29.
Positioning support base 28 is unclamped again, the connection of hydraulic elongator 27 and periphery vehicle grinder part 29 is disengaged, then
Hydraulic elongator 27 is unloaded, then unloads the connected pinboard 23 for connecting the first pedestal 13 and substrate 1, it is finally that fluid pressure type is pre-
Force applying assembly integral demounting is answered to get off.
The periphery vehicle grinder part prestressing force removed holding component is placed to together with the periphery vehicle grinder part 29 in it
The Working position of lathe can select three kinds of modes that lathe reducing sleeve 37 is connected with machine tool chief axis according to actual processing needs,
First way is that lathe reducing sleeve 3 is inserted directly into the spindle hole of lathe, and the second way is to fix machine using scroll chuck
Bed reducing sleeve 3, the third mode are to fix lathe reducing sleeve 3 using driver plate.And 29 other end of periphery vehicle grinder part, according to reality
Border processing needs, and can select that the top of tailstock tool is directly acted against workpiece end, or reconnect one in workpiece end
A lathe reducing sleeve 3, and tailstock tool is top, acts directly against on lathe reducing sleeve 3.
Start lathe, machines or grind processing by the external disc vehicle grinder part of lathe 29, until process finishing, wait for
Workpiece temperature is cooled to room temperature, by periphery vehicle grinder part prestressing force keep component together with the periphery vehicle grinder part 29 in it from
It is removed on lathe, then unclamps periphery vehicle grinder part stop nut 32, realize the unloading of pretension, finally grind periphery vehicle
Workpiece 29 unloads, and the pre-stressed machining of periphery vehicle grinder part 29 terminates.
Embodiment three：Pretension is applied to plane milling grinder part 11, but selects fluid pressure type prestress application component and plane
Milling workpiece prestressing force keeps component to be used cooperatively, and the application process of pretension can refer to embodiment two, and pretension
Holding process can refer to embodiment one.
Example IV：External disc vehicle grinder part 29 applies pretension, but selects mechanical prestress application component and outer
Disc vehicle grinder part prestressing force keeps component to be used cooperatively, and the application process of pretension can refer to embodiment one, and pre-
The holding process of pulling force can refer to embodiment two.
In addition, prestress clamp is in actual use, substrate 1, the first pedestal 13, the second pedestal 14 in fixture,
Adjusting screw 15, spacing locking nut 20, bolt 21 and connected pinboard 23 are common component and need to only prepare a set of, then root
According to the pre-stressed machining requirement of different workpieces, the appropriate other component replaced in fixture, you can finally assemble actually required
Prestress clamp.
Scheme in embodiment be not to limit the scope of patent protection of the present invention, it is all without departing from carried out by the present invention etc.
Effect implements or change, is both contained in the scope of the claims of this case.
