Description

General frock of valve gasket board

Technical Field

The utility model relates to a tool for the production and manufacture of a hydraulic support for fully-mechanized mining intelligent manufacturing of a coal mine, in particular to a general tool for a valve gasket plate.

Background

In the production and manufacture of the fully-mechanized intelligent hydraulic support, the valve gasket plate is used for fastening the valve, the valve body and the valve cover. Such as figure 1a being a front view of the valve shim plate, figure 1b being a left side cross-sectional view of the valve shim plate, figure 2 being an assembly view, the link body 1 and the valve pad 2 are fixed to the link body 1 by assembly and welding. The valve gasket plate is used for assembling and welding the valve gasket plate on the structural member, and the valve gasket plate is a part assembling method for fully-mechanized intelligent manufacturing of the hydraulic support.

The prior art comprises the following steps:

the R6 dimension of the valve shim plate of FIG. 1a is the desired dimension, and the R6 horizontal center and vertical center positioning dimensions are determined by accounting for the positional relationship in the assembly drawing of the assembly of FIG. 2. The tooling locating plate shown in figure 3 is designed. The technical staff designs the corresponding tool locating plate according to the valve gasket plate specification selected by the design technical staff.

The current state of the art is:

in the first case, when the number of valve gasket plates is small, a riveter in a production workshop can realize the assembly relation between the valve gasket plates and the valve body according to the traditional operation mode of marking, positioning and assembling according to the dimension marked by the two-dimensional drawing;

in the second case, when the number of valve gaskets is large, the riveting worker in the production workshop can use the tooling positioning plate designed by the process technician and shown in fig. 3 to realize the assembly relationship between the valve gaskets and the valve body.

The specific method is as follows:

the riveting worker in the production workshop firstly marks the horizontal center line of the connecting rod body 1 in fig. 2, then coincides the horizontal center line of the tooling positioning plate designed by the technical staff in fig. 3 with the horizontal center line of the connecting rod body 1 marked by the riveting worker in fig. 2, ensures 925 size and finally passes through the shaft to be assembled. The positional relationship of the valve backing plate can be located.

Disadvantages of the prior art:

the production workshop riveter spends a large amount of time marking equipment, has the riveter to draw the wrong risk of location datum line, positional relationship mistake, causes unnecessary to repair, delays the production progress, has reduced production efficiency.

If the tooling positioning plates designed by technical staff are used, because the valve gasket plate on each set of hydraulic support is different in type and size and two-dimensional drawing positioning size, each set of product is at least designed with more than one tooling positioning plate, and the tooling positioning plates are disposable;

because the specifications of the valve gasket plate in each set of hydraulic support structural member are different, the valve gasket plate is various, and the repeated utilization rate of the valve gasket plate in the next set of product is 0, different tooling positioning plates are required to be designed for each set of product to meet the requirement of assembly size. The tool positioning plate body is a tool for improving the product quality, but brings more material processing cost to a factory workshop, wastes raw materials and increases labor force;

in some cases, the positioning size interval between valve gaskets is too large, and the weight of a positioning plate tool designed therewith is increased, so that an operator is difficult to carry the tool when assembling parts, the labor intensity is increased, and personal safety accidents are easily caused.

In view of this, the present utility model has been made.

Example 1

As shown in fig. 4a and 4 b:

the radius of the long hole on the long strip plate 3 of the machined long hole is consistent with the radius of the valve gasket plate on the design drawing, the two long strip plates 3 are horizontally arranged, the two long strip plates 3 are vertically arranged, the two long strip plates are adjusted to the end point by sliding up and down and left and right, the long strip plates are locked by a bolt-4 jackscrew, the bolt-4 and the long hole are in transition fit, and the end points are locked into geometrical quadrangles around, so that the long strip plates cannot slide up and down and left and right mutually. Finally, the valve gasket plate is embedded into a cylinder (one side with threads) at one end of the bolt, and the assembly is completed.

And the production workshop riveting worker selects a bolt II 5 with the same specification and radius size according to the size of the circular arc radius of the valve gasket plate on the design drawing, and the bolt II 5 is in transition fit with the long hole on the long slat 3 and the radius size of the valve gasket plate 2.

And the riveter embeds the second bolt 5 into the long hole track and slides the second bolt to the size required by the design drawing according to the well calculated positioning point of the design drawing.

In the figure, the number of the long strips 3 is 4, and the number can be changed to 3 according to specific needs. In addition to the above-mentioned manner, more positioning points are obtained, and the length of the long slat 3 can be lengthened or shortened to achieve the purpose.

The key points of the technology of the utility model are as follows:

the utility model mainly adjusts the long hole strip plate to be a quadrilateral before assembling the structural member valve gasket plate, and locks the long hole strip plate by using a bolt jackscrew. Calculating the position relation between the aperture of the valve gasket part and the horizontal and vertical distance of the valve gasket on an assembly drawing, embedding a bolt matched with the valve gasket with the arc radius into a long hole, and sliding the bolt in a long hole track to the size required by a design drawing.

The utility model has the beneficial effects that:

1. the positioning tool for the valve gasket ensures the precision of the valve gasket part in the assembly structural part and prevents unnecessary repair caused by unqualified assembly quality. The riveting tool is light and convenient, is favorable for carrying and assembling by a riveting tool, and reduces the occurrence of personal safety accidents.

2. The valve gasket positioning tool saves the scribing and positioning time of a riveter in a production workshop, enables the assembling procedure of the riveter to be more systematic and standardized, and provides better support for the subsequent welding and assembly procedure.

3. According to the valve gasket positioning tool, through the mode that the long holes on the long strip plates are locked by the bolt jackscrews and then the other bolts are embedded to slide in the long holes, the drawing positioning requirements of several or more than ten valve gaskets can be met.

According to the utility model, the long holes of the long plates on the device can be mutually adjusted to be quadrilateral up and down and left and right, and the embedded bolts slide in the long hole tracks of the long plates by utilizing the self-locking of the jackscrews. The production efficiency is improved, and the generalization is realized. The production workshop riveter only needs to adjust the sliding. The device can be used for designing various types of tools such as geometric quadrilaterals or geometric triangles with different lengths.
