On empty pump, no longer dismantled into no special reason after an entirety with lathe row.
The present invention carries out workpiece fixation procedure：
Exemplary, the present embodiment is illustrated exemplified by opening 4 fixing holes：
First, adaptation sole plate 1 is carried out according to the size of lathe, the upper surface of sole plate 1 is processed between 50mm*50mm
Away from or 100mm*100mm spacing be used for install the back of the body draw bolt and floating positioning pin nail basic hole 4；
To 5 four jiaos of workpiece to be fixed and/or edge fixing hole 51, as shown in Figure 5；
According to the size of workpiece 5, bolt 2 and floating pin 3 is drawn to be fixed and be installed in basic hole 4 back of the body, it is exemplary,
The back of the body draws bolt 2 and floating pin 3 diagonally to be arranged in the corner of workpiece 5；
Then the pin 32 in floating pin 3 is risen by die nut, then inserted the corresponding fixing hole 51 of workpiece
Enter；
Finally draw bolt 2 to be risen by die nut the back of the body, fixation is engaged with the screw thread on fixing hole 51, such as Fig. 6 institutes
Show.
Beneficial effects of the present invention：
1st, technology time shortens：The hole system of gene basis plate is the spacing of standard, and different lathes all install this
After application invention, also all unify clamping benchmark, eliminate the feelings that the original T-slot of different lathes is not of uniform size, spacing differs
Condition；The clip position of the part position different according to hole system is selected in suitable clamping and positioning hole, technological process file
Only identify installation site.Design, the selection of pressing plate size/specification, clamping explanation without carrying out frock clamp again
The drafting of figure, greatlys save the time of technology preparation and improves the quality of work；Because eliminating special tool clamping
The input of tool, while also reducing the production time of workpiece；
2nd, the disposable input of at least 95% special fixture is reduced：The invention can be adapted to thousands of kinds of plate parts plus
Work is clamped, and can cancel the special fixture input of conventional method；
3rd, the Operational preparation time significantly reduces：After the invention device is disposably installed on lathe, without extra
Component is clamped, installing workpiece only needs a standard inner hexagon spanner, so that traditional approach equally to be prepared to bolt, pressure
The times such as plate, nut, support block, the installation tool of different size are reduced to 0；
4th, workpiece time that changes the outfit significantly reduces：The invention device be standardization, it is modular, according to standard operation, put down
Workpiece below equal 1 meter of clamping one is less than 3 minutes, and traditional approach needs 5~30 minutes/part；If the invention device
On single workbench lathe, lathe downtime can be greatly lowered on year-on-year basis, that is, improve more than utilization rate of equipment and installations OEE5%；
The invention device, which is equally applicable to switch between multiple manufacturing procedure/work steps of a workpiece, different process/work steps, only changes to work
Make another position of platform, without being debugged and being changed frock clamp；
5th, reduction operative employee's labor intensity and difficulty：The invention operates brief introduction, and standard is used according to the coordinate position of hole system
Instrument can mount and dismount part, new staffs training 1 hour can skilled operation, eliminate conventional method for complicated and letter
The installing/dismounting difficulty difference of single part；
6th, input cost is low：Lathe is only superimposed with the invention device without being transformed；The invention device structure phase
To simple, pure mechanic structure, the complex mechanism such as no automation, electronization, hydraulic mechanism, cost input is compared with Zero-point positioning system
It is low.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
