Abstract
The present invention relates to a kind of sensor fixing structure and installation method of automatic servo pressing machine, ball screw upper and lower end is connected with top chock and step with lower bearing respectively by upper bearing (metal), coaxial setting pressure sensor on ball screw between top chock with step, be positioned on the ball screw above upper bearing (metal) and be rotary with bearing lock nut and locking nut, and upper bearing (metal) by bearing lock nut adjustment locking, lower bearing lower surface with near the annular firmware on ball screw.Collar nut is regulated to get final product the initial pressure value of controlled pressure sensor.The present invention is by above structure, achieve when rotating under the drive of screw mandrel in external motor, screw mandrel can be subject to power upwards, this power is delivered on lower bearing by the annular firmware on screw mandrel, be delivered on step by lower bearing again, and then be reflected on pressure sensor, thus realize the reading to real-time pressure data.
Description
Technical field
The present invention relates to a kind of automatic servo pressing machine, sensor fixing structure and installation method in especially a kind of automatic servo pressing machine.
Background technology
Current automatic servo press is not general at home, is more common in the servo press of America and Europe and Japan.In the design of main flow, the concentricity of the subject matter that the pressure sensor in automatic servo press faces and sensor and mill auxiliaries structure thereof, once there is deviation in concentricity, unavoidably will there is deviation in whole measurement data, equipment action under the state of relative decentraction for a long time, very likely can cause the infringement to equipment self, thus cause permanent deviation, until scrap.
The solution of the present invention is devoted to design a kind of simple structure being applicable to the installation of servo press pressure sensor effectively controlling concentricity.
Summary of the invention
The present invention is sensor fixing structure and the installation method that will provide a kind of automatic servo pressing machine, stablize in order to meet servo press, accurately, the lasting requirement must reading pressure data, and can meet this require frame for movement must simplify as far as possible.
For achieving the above object, technical scheme of the present invention is: a kind of sensor fixing structure of automatic servo pressing machine, comprise ball screw, upper bearing (metal), lower bearing, top chock, step, pressure sensor, on ball screw, lower end is connected with top chock and step with lower bearing respectively by upper bearing (metal), coaxial setting pressure sensor on ball screw between top chock with step, be positioned on the ball screw above upper bearing (metal) and be rotary with bearing lock nut and locking nut, and upper bearing (metal) is by bearing lock nut adjustment locking, lower bearing lower surface with near the annular firmware on ball screw.Upper and lower bearing is band thrust ball needle bearing.
A kind of method of installing the sensor fixing structure of automatic servo pressing machine: first successively lower bearing and step are inserted in ball screw, after pressure sensor is loaded step, install bearing block and upper bearing (metal) again, subsequently with bearing lock nut by it locking, and the initial pressure value by regulating the tightness of bearing lock nut to determine pressure sensor, again locking nut is installed after completing, guarantees that total can not loosen.
Beneficial effect of the present invention is: after pressure sensor installs, and the movement of upper and lower bearing block meeting limiter pressure sensor, therefore can not produce vibration interference when guaranteeing action.Upper and lower bearing adopts band thrust ball needle bearing, guarantees that screw mandrel can not produce extra mechanical friction and cause structure to produce deviation when axis and radial motion, also ensure that the concentricity of whole mechanism simultaneously.The pressure that bearing lock nut can regulate pressure sensor to be initially subject to, to facilitate the adjustment of zero-bit.
The better simply frame for movement of the present invention, adopts more conveniently installation method, can realize the real-time reading to pressure value, and ensure that its numerical value can not cause data distortion because of the mechanical friction in the deviation of Automatic manual transmission or action.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the present invention is described further.
As shown in Figure 1, a kind of sensor fixing structure of automatic servo pressing machine, comprises ball screw 9, lower bearing 7, step 6, pressure sensor 5, top chock 4, upper bearing (metal) 3, bearing lock nut 2 and locking nut 1.
Pressure sensor 5 is fixedly situated between by upper and lower bearing block 4,6, upper and lower bearing block 4,6 is fixed with again upper and lower bearing 3,7 respectively, upper and lower bearing 3,7 center is inserted in and is arranged on ball screw 9, one end of lower bearing 7 is near the annular firmware 8 on ball screw 9, upper bearing (metal) 3 one end is fixed by a bearing lock nut 2, and can not loosen when adding a locking nut 1 to guarantee action.
During installation, first successively lower bearing 7 and step 6 are inserted in ball screw 9, after pressure sensor 5 is loaded step 6, install bearing block 4 and upper bearing (metal) 3 again, subsequently with bearing lock nut 2 by it locking, and the initial pressure value by regulating the tightness of bearing lock nut 2 to determine pressure sensor, after completing, locking nut 1 is installed again, guarantees that total can not loosen.
When ball screw 9 action, due to the effect of external force, ball screw 9 will be subject to a power upwards, and this power is delivered on each mechanical part above-mentioned and on pressure sensor 5 by the annular firmware 8 on ball screw 9, realizes the object obtaining pressure value in action.
When press is in action, outside mechanism and parts will give ball screw 9 one power around axial rotation, ball screw 9 is by by himself helicitic texture, a downward pressure is formed to parts mounted thereto, due to the interaction principle of power, as described above, this power will be reacted on ball screw 9 by screw thread conversely.
First this reaction force can be delivered on lower bearing 7 by the annular firmware 8 on screw mandrel 9, lower bearing 7 and step 6 are parts of close-fitting, therefore, step 6 also can be subject to an onesize power upwards simultaneously, and be applied on pressure sensor 5 at this moment, after pressure sensor 5 one end is stressed, this power is passed to top chock 4 above, top chock 4 with against a fixed part, these parts are fixed parts, form the support to this power, thus achieve the balance of whole pressing machine internal forces.
And now pressure sensor 5 will be subject to the effect of this power and form valid reading, the object of real-time monitor force data can be reached by reading this reading.
