Embodiment
In order that those skilled in the art more fully understand the technical scheme in the utility model, below in conjunction with this reality
With the accompanying drawing in new embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that
Described embodiment is only the utility model part of the embodiment, rather than whole embodiments.Based on the utility model
In embodiment, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, it should all belong to the scope of the utility model protection.
Fig. 1 is the press fitting cylinder schematic cross-section of embodiment electrical servo press-loading device.As shown in figure 1, the utility model is real
Applying the electrical servo press-loading device of example offer includes press fitting cylinder, and press fitting cylinder includes cylinder body 11, lead screw shaft 12, screw 13 and pressure
Sensor 14.There is inner chamber, inner chamber can be used for the portions such as installation lead screw shaft 12, screw 13 and pressure sensor 14 among cylinder body 11
Part.
As shown in figure 1, in the present embodiment, lead screw shaft 12 and screw 13 are installed in the inner chamber of cylinder body 11, and silk
Thick stick axle 12 and screw 13 are threadedly coupled.To prevent screw 13 from being rotated with lead screw shaft 12, the intracavity sidewall of cylinder body 11 sets anti-rotation
Guide rail 111, anti-rotation guide rail 111 coordinate limitation screw 13 to be rotated relative to cylinder body 11 with screw 13, also just limit screw 13 with silk
Thick stick axle 12 rotates.In practical application, anti-rotation guide rail 111 can be antirotation keys as depicted, can also be commonly used such as prior art
Anti-rotation spline.
As shown in figure 1, for reduce screw 13 length, avoid screw 13 directly with component contact to be processed, the present embodiment
The electrical servo press-loading device of offer also includes Fitted Axles 18, and Fitted Axles 18 are fixedly connected with screw 13, in the driving of screw 13
Lower relative cylinder body 11 moves axially.In addition, be the durability for improving screw 13, the antirotation keys in the present embodiment directly with press fitting
Axle 18 coordinates, and limitation screw 13 rotates with lead screw shaft 12.
Continuing with referring to Fig. 1, the pressure sensor 14 in the present embodiment is in annular shape.Pressure sensor 14 includes fitting
The inner ring portion 141 of interior mother rib lateral rotundum, the outer ring portion 142 on the outside of annulus and it is arranged between inner ring portion 141 and outer ring portion 142
Deformation signal output section 143.Pressure sensor 14 can be sleeved in lead screw shaft 12, inner ring portion 141 in the axial direction with silk
Thick stick axle 12 is fixedly connected, and outer ring portion 142 is fixedly connected with cylinder body 11 in the axial direction.
In addition, electrical servo press-loading device provided in an embodiment of the present invention also includes servomotor, the output of servomotor

Axial movement.
When electrical servo press-loading device works, servomotor driving lead screw shaft 12 rotates, and props up Fitted Axles 18 to be processed
Part simultaneously applies active force to part to be processed, and reaction force caused by part to be processed is acted on by Fitted Axles 18, screw 13
In lead screw shaft 12 so that lead screw shaft 12 is axially having a micro-displacement.Because the inner ring portion 141 of pressure sensor 14 and leading screw
Axle 12 is fixedly connected, so the inner ring portion 141 of pressure sensor 14 moves also with the movement of lead screw shaft 12；And because pressure
The outer ring portion 142 of sensor 14 is fixedly connected with cylinder body 11, and cylinder body 11 is fixed, so inner ring portion 141 is relative to outer ring portion
142 displacements, pressure sensor 14 is set to produce elastic deformation, and elastic deformation caused by pressure sensor 14 make it that deformation signal is defeated
Go out portion 143 and export deformation signal.In practical application, the deformation signal size in pre-stage test data and actual production, just
Counteractive size can be determined, has also determined that the active force that electrical servo press-loading device is acted on part to be processed is big
It is small.
The electrical servo press-loading device provided using the utility model embodiment, pressure sensor 14 is not such as prior art
The working end (the namely working ends of Fitted Axles) of press-loading device is arranged on, and is provided in the upside of press-loading device and substantially
Fixed (displacement is smaller) relative to cylinder body 11, the signal transmssion line for connecting pressure sensor 14 and corresponding controllers will not be with pressure
Dress axle 18 is moved up and down so that signal transmssion line can be arranged in outside the operating space of press-loading device, avoid signal during work from passing
Defeated line is wound and pulled apart, and improves the reliability during work of electrical servo press-loading device.
As shown in figure 1, the press fitting cylinder in the present embodiment also includes locking nut 15, positioning shaft shoulder is set in lead screw shaft 12
121, the power intake side of lead screw shaft 12 is provided with the external screw thread coordinated with locking nut 15.The inner ring of pressure sensor 14
Against the positioning shaft shoulder 121 of lead screw shaft 12, the locking nut 15 that opposite side is installed in lead screw shaft 12 compresses the side of portion 141；
In this way, the inner ring portion 141 of pressure sensor 14 is fixedly connected with lead screw shaft 12.
Further, in order to avoid pressure sensor 14 rotates with lead screw shaft 12, in the utility model embodiment, pressing
The both sides of force snesor 14 are additionally provided with thrust ball bearing 16.Thrust ball bearing 16 can be kept away while axial force is transmitted
The inner ring portion 141 for exempting from pressure sensor 14 rotates, also it is avoided that 14 inner ring portion of pressure sensor, 141 relative outer ring portion 142 is in week
Deformed upon to direction, influence detection of the deformation signal output section 143 to axial force size.
Continuing with referring to Fig. 1.In the present embodiment, cylinder body 11 includes Master cylinder body 112, upper cylinder cover 113 and lower cylinder cap 114.
Upper cylinder cover 113 is arranged on the corresponding power intake side of lead screw shaft 12 of Master cylinder body 112, and lower cylinder cap 114 is arranged on the correspondence of Master cylinder body 112
The side of Fitted Axles 18.Upper cylinder cover 113 is provided with lead screw shaft and sets Fitted Axles 18 to pass through hole by hole, lower cylinder cap 114.
In the present embodiment, the outer ring portion 142 of pressure sensor 14 is threaded hole, the corresponding pressure sensor of upper cylinder cover 113
The position of 14 screwed holes sets bolt hole.Bolt through foregoing bolt hole is threadedly coupled with the screwed hole in outer ring portion 142 and will pressed
Force snesor 14 is fixed on upper cylinder cover 113.Certainly, in other embodiments, the outer ring portion 142 of pressure sensor 14 can also lead to
Fixed form known to mechanical field is crossed to be fixed on upper cylinder cover 113 or Master cylinder body 112.
In the present embodiment, in order to ensure the stationarity of the rotation of lead screw shaft 12, and enable lead screw shaft 12 with respect to cylinder body 11
Successfully move axially, lead screw shaft 12 and cylinder cap are by setting NU cylinder roller bearings 17 in the present embodiment between hole.
In addition, to avoid adjacent bearing that crosstalk occurs, avoiding locking nut 15 from interfering the outer ring of NU cylinder roller bearings 17, lock
Upper pad 19 is tightly set between nut 15 and NU cylinder roller bearings 17, NU cylinder roller bearings 19 and adjacent thrust ball bearing 16 it
Between set underlay 20.
It should be noted that in the present embodiment, thrust ball bearing 16 and pressure sensor 14 are arranged on compared to NU cylindrical rollers
The more inner position of bearing 17；Thrust ball bearing 16, the independence of the function of NU cylinder roller bearings 17 are considered, in other implementations
In example, thrust ball bearing 16 and pressure sensor 14, the position of NU cylinder roller bearings 17 can also exchange, as long as upper cylinder cover
Position has supporting structure corresponding to 113.
