Problems solved by technology

When the next workpiece is switched, it has to be readjusted, which is very cumbersome and requires certain skills and experience
[0004] In addition, due to the many specifications and types of wedge gate valves, the above-mentioned traditional precision grinding fixtures are not universal. Therefore, as the variety of valves increases, the number of tooling fixtures also increases.
Production management is very inconvenient, increases costs, and easily leads to delayed delivery

Embodiment 1

[0019] The basic structure of the universal fine grinding jig with adjustable gate valve plate in this embodiment is as follows: image 3 and Figure 4 As shown, it includes a disc-shaped wedge-angle inclined formwork 1 with a workpiece 2 placed on the upper surface. The upper surface of one end of the wedge-angle inclined formwork is fixed with a baffle plate 4 for workpiece positioning, and the upper surface of the other two sides is provided with a large bottom and a small upper surface. T-shaped sliding groove, in which the lower end of the inverted compression bolt 5 is installed to form a moving pair. The upper end of the compression bolt 5 is screwed to press the nut of the pressure plate 3, so the compression bolt can be adjusted according to the size of the workpiece. Move the position in the groove, so as to meet the clamping needs of different specifications of the gate. In addition, the lower surface of one end of the wedge-angle inclined formwork 1 fixing the ba...

Embodiment 2

[0021] The specific structure of the adjustable universal fine grinding jig of the gate valve gate plate in this embodiment is as follows: Figure 5 and Figure 6 As shown, the basic structure is similar to that of Embodiment 1. The lower surface of one end of the wedge angle inclined formwork 1 fixed baffle plate 4 is embedded with a fixed hinge block 1-1, and the corresponding positions of the lower surface of the hinge block 1-1 and the upper surface of the bottom plate 9 are respectively It has V-shaped grooves with opposite openings, and hinge pins 10 are installed in the two V-shaped grooves, thereby forming a hinged connection structure between one end of the wedge-angle inclined formwork 1 and the bottom plate 9 .

[0022] In addition, this embodiment is improved on the basis of Embodiment 1. The upper surfaces of both sides of the wedge-angle inclined formwork 1 and the connection between the bottom plate 9 and the compression bolt 7 are respectively provided with ci...

Abstract

The invention relates to a general accurate grinding clamp with an adjustable sluice valve flashboard and belongs to the technical field of machining. The general accurate grinding clamp comprises a wedge angle slope moldboard with an upper surface provided with a workpiece, one end of the wedge angle slope moldboard is used for fixing a retaining plate for limiting the workpiece, and two sides of the wedge angle slope moldboard are provided with compression bolts for pressing and holding the workpiece through pressing plates. The general accurate grinding clamp is characterized in that one end of the wedge angle slope moldboard for fixing the retaining plate is hinged onto a base plate, one end of the wedge angle slope moldboard far away from the retaining plate is padded on an adjusting base plate with preset slope, and the lower ends of a locking bolt penetrating through the adjusting base plate and an adjustable bolt screwed on the adjusting base plate are respectively connected with and support on the base plate. When the flashboard to be machined is placed on the wedge angle slope moldboard, the retaining plate can be used for locating, the pressing plates can be used for pressing and fixing, when the angle of inclination needs tuning slightly, users can only screw the adjustable bolt, change hinged inclination of the wedge angle slope moldboard and then adjust, the locking bolt is used for locking, and the general accurate grinding clamp is convenient.

Description

technical field [0001] The invention relates to a fixture, in particular to a general-purpose precision grinding fixture with an adjustable gate valve gate, which belongs to the technical field of mechanical processing. Background technique [0002] The precise grinding of the sealing surface of the wedge gate valve is a difficult point in the processing technology. Due to the cumulative error in the processing of the valve body, it is impossible to make the wedge angle of each valve body 5° the same during the processing of a batch of valve bodies, but to adjust the wedge angle of the sealing surface of the gate plate to the same value as The wedge angle of the valve body is the same, so as to ensure the consistency of the sealing surface, and the sealing performance of the product can only be guaranteed after assembly. [0003] For the above reasons, when the gate is finely ground, it is necessary to adjust the inclination angle of the gate according to the detection resu...
