Further, in aforesaid Shear sharpener, scissors fixture tilts forward and back angle regulating positioning device, wherein: on locating piece, be provided with housing screw, housing screw is successively through pressing closer the side of connecting plate after the arc-shaped through-hole on locating piece and cross contiguous block.
Further, in aforesaid Shear sharpener, scissors fixture tilts forward and back angle regulating positioning device, wherein: on spring support, be provided with adjustment screw, adjustment screw fixes with spring bearer plate through after spring support, spring bearer plate is connected with one end of Compress Spring, and the other end of Compress Spring is connected with locating piece.
By the enforcement of technique scheme, the present invention have advantages of can increase work efficiency, and can tilting forward and back angle and carry out accurately regulating location scissors fixture.
Accompanying drawing explanation
Fig. 1 is the structural representation that tilts forward and back angle regulating positioning device of scissors fixture in Shear sharpener of the present invention.
Fig. 2 is the decomposition texture schematic diagram of the front and back inclination angle trimming regulating mechanism shown in Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Fig. 1, shown in Fig. 2, in described Shear sharpener, scissors fixture tilts forward and back angle regulating positioning device, comprise: mainframe 1 and scissors fixture 13, between mainframe 1 and scissors fixture 13, be provided with and can adjust the front and back inclination angle trimming regulating mechanism that scissors fixture tilts forward and back angle, in the present embodiment, the structure of described front and back inclination angle trimming regulating mechanism is: the side at mainframe 1 is installed with cantilever beam 2, one end of connecting axle 3 is fixedly mounted on cantilever beam 2, the other end of connecting axle 3 is through the top that is movably arranged on cross contiguous block 14 after connecting plate 6, in the bottom of cross contiguous block 14, be provided with the arc-shaped through-hole 141 that perforation cross contiguous block 14 and longitudinal section are circular shape, cross contiguous block 14 outsides that are positioned at arc-shaped through-hole 141 positions are installed with spring support 7, Compress Spring 10 is installed in spring support 7, one end of Compress Spring 10 is connected with the inwall of spring support 7, the other end of Compress Spring 7 is connected with locating piece 11, attachment screw 121 is successively through after locating piece 11 and arc-shaped through-hole 141, locating piece 11 and connecting plate 6 being fixed, connecting plate 6 fixes with cantilever beam 2, on cantilever beam 2 tops, be installed with gripper shoe 4, inclination angle trimming regulating screw 5 is through the left end top surface that is pressing cross contiguous block 14 after gripper shoe 4, in the present embodiment, in order freely to adjust the elastic force of Compress Spring 10, on spring support 7, be provided with adjustment screw 8, adjustment screw 8 is passed spring support 7 afterwards and spring bearer plate 9 fixes, spring bearer plate 9 is connected with one end of Compress Spring 10, and the other end of Compress Spring 10 is connected with locating piece 11, in the present embodiment, for locating piece 11 is more firmly fixed with connecting plate 6, housing screw 12 has been installed on locating piece 11, housing screw 12 is successively through pressing closer the side of connecting plate 6 after locating piece 11 and arc-shaped through-hole 141, in practical operation, scissors fixture 13 is fixed on the top of cross contiguous block 14, and scissors fixture 13 is synchronized with the movement with cross contiguous block 14.
Operation principle of the present invention is as follows: in the time the right-hand member of scissors fixture 13 need to being moved upward, first be rotated down inclination angle trimming regulating screw 5, the screw rod bottom surface of inclination angle trimming regulating screw 5 moves downward the left end that heads on cross contiguous block 14, because cross contiguous block 14 now rotates around connecting axle 6, so in the process constantly moving downward at cross contiguous block 14 left ends, the right-hand member of cross contiguous block 14 can constantly move upward and synchronously drive the right-hand member of the scissors fixture 13 being fixedly connected with it to move upward, until reach the position that the required adjustment of scissors fixture 13 arrives, simultaneously, in the process that the left end of cross contiguous block 14 constantly moves downward, Compress Spring 10 can be gradually reduced, when the right-hand member of the cross contiguous block 14 of having heightened need to move downward while carrying out angle adjustment, only need rotate up screw rod bottom surface that inclination angle trimming regulating screw 5 makes inclination angle trimming regulating screw 5 and leave the left end top surface of cross contiguous block, at this moment, under the elastic-restoring force effect of Compress Spring 10, Compress Spring 10 can drive cross contiguous block 14 to rotate backward around connecting axle 6, make the left end top surface of cross contiguous block 14 along with inclination angle trimming regulating screw 5 moves upward, in the process constantly moving upward at cross contiguous block 14 left ends, the right-hand member of cross contiguous block moves downward constantly moving downward and synchronously driving with the right-hand member of scissors fixture 13, until reach the position that the required adjustment of scissors fixture 13 arrives.The present invention have advantages of can increase work efficiency, and can tilting forward and back angle and carry out accurately regulating location scissors fixture.
