The axis hole of rotating shaft cooperation, two on resupination framework rotating shaft all rotates in the axis hole of the support plate being installed on respective side, resupination framework
Upper surface be provided with storage tank, hold-down frame is installed on the upper surface of resupination framework, and hold-down frame is passed through with resupination framework
Mode connects for screw is fixed, and the lower surface of hold-down frame is provided with storage tank, and resupination framework is with the central part of hold-down frame and connects
The centre bore of containing cavity, two support plates are symmetrically arranged with through hole, and the shape of through hole is matched with the section of gripper shoe, each
Two rows through hole is provided with plate, and every exhausting hole includes at least two through holes being divided into rotating shaft both sides, positioned at upper row
The top surface of through hole and hold-down frame resupination framework when being positioned horizontally in above resupination framework lower surface flush, positioned at lower row's
The upper surface flush of hold-down frame, the quantity of gripper shoe when the top surface of through hole and hold-down frame are positioned horizontally in below resupination framework
Equal with the number of openings of every exhausting hole, gripper shoe penetrates from the through hole of a support plate, wears from the corresponding through hole of another support plate
Go out.
The rectangular cross-section of described gripper shoe.
Described every exhausting hole all includes two through holes, and two through holes are divided into the both sides of rotating shaft.
The present invention has advantages below:Present configuration is simple, easy to operate, and workpiece two sides can be processed, and improves and adds
Work efficiency rate.By the rotation of resupination framework, drive the hold-down frame being fixedly connected with resupination framework and be clamped in resupination framework
Workpiece and hold-down frame between rotates around the shaft, by gripper shoe is respectively arranged in upper exhausting hole or lower exhausting hole, realizes
Workpiece front station is supported with fixing or reverse side station support fixation.Achieve clamped one time and just can carry out two sides processing, reduce
Clamping error, it is to avoid the crushing of machined surface, improves work efficiency, simple to operate.

Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to described below:
As shown in Figure 2 and Figure 3, a kind of turnable jig, it includes support base 1, resupination framework 2, hold-down frame 3 and supports
Plate 4, the top of support base 1 is provided with two support plates be arrangeding in parallel 5, and resupination framework 2 is arranged between two support plates 5, upset
Framework 2 is provided with a rotating shaft 6 on the edge of two support plates 5, two support plates 5 is provided with one and joins with rotating shaft 6
The axis hole closing, two on resupination framework 2 rotating shaft 6 all rotates and is installed in the axis hole of support plate 5 of respective side, resupination framework 2
Upper surface is provided with storage tank 7, and hold-down frame 3 is installed on the upper surface of resupination framework 2, and hold-down frame 3 is led to resupination framework 2
Cross screw 8 to be connected, the lower surface of hold-down frame 3 is provided with storage tank 7, and the central part of resupination framework 2 and hold-down frame 3 is equal
For connecting the centre bore 9 of containing cavity, as shown in figure 1, through hole 10, the shape of through hole 10 and support are symmetrically arranged with two support plates
Match in the section of plate 4, the rectangular cross-section of gripper shoe 4 in this enforcement, and each support plate is provided with two rows through hole 10,
And often exhausting hole 10 includes at least two through holes 10 being divided into rotating shaft 6 both sides, in the present embodiment, every exhausting hole 10 all includes two
Individual through hole 10, two through holes 10 are divided into the both sides of rotating shaft 6, positioned at top surface and hold-down frame 3 horizontal position of the through hole 10 of upper row
The lower surface flush of resupination framework 2 when resupination framework 2 top, positioned at top surface and hold-down frame 3 water of the through hole 10 of lower row
The upper surface flush of prosposition hold-down frame 3 when resupination framework 2 lower section, as shown in Figure 2 and Figure 3, the quantity of gripper shoe 4 with every
Through hole 10 quantity of exhausting hole 10 is equal, and gripper shoe 4 penetrates from the through hole 10 of a support plate 5, leads to from the correspondence of another support plate 5
Hole 10 passes.
The work process of the present invention is as follows:As shown in figure 1, resupination framework 2 is rotated to its lower surface and upper exhausting hole 10
Top surface flush, then up exhausting hole 10 be inserted into gripper shoe 4, gripper shoe 4 is supported by the upper exhausting hole 10 of two support plates 5
Two ends, thus realizing supporting resupination framework by gripper shoe 4 is fixing, workpiece is positioned in the storage tank 7 of resupination framework 2, so
Afterwards hold-down frame 3 is fastened on resupination framework 2, workpiece top is similarly positioned in the storage tank 7 of hold-down frame 3, by screw 8
Be connected resupination framework 2 and hold-down frame 3, thus the clamping to workpiece is realized by hold-down frame 3 and resupination framework 2, now,
Process tool just can be processed to the upper surface of workpiece by the center of hold-down frame 3, after upper surface completion of processing, withdraw from and prop up
Fagging 4, resupination framework after 180 ° of 6 rotation, gripper shoe 4 is installed in lower exhausting hole 10 around the shaft, is supported by gripper shoe 4 is fixing
The upper surface of hold-down frame 3, as shown in figure 4, now, process tool just can pass through the centre bore 9 of resupination framework under workpiece
Surface is processed, it is achieved thereby that clamped one time just can carry out two sides processing.
