Description

Technical Field

[0001] The utility model relates to the technical field of valve body manufacturing, in particular to a combined processing device for a pilot valve seat. Background Art

[0002] The function of the pilot valve seat is to fix the pilot valve and integrate the pilot valve into a module, which is easy to install and control.

[0003] The shapes and sizes of pilot valve seats vary depending on the shape and size of the pilot valve and the degree of integration. However, no matter what kind of pilot valve seat it is, there are many holes neatly arranged. In the prior art, it is usually processed one by one on a regular piece of metal material using a drilling machine, so the efficiency is relatively low, and the spacing between the holes will also have errors in the process of moving the metal material, resulting in mismatching problems during the assembly process.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0005] The utility model aims to address the deficiencies of the prior art and thus provide a combined processing device for a pilot valve seat which can process multiple holes at one time and has higher efficiency and higher precision.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a combined processing device for a pilot valve seat, comprising a chuck mounting seat, a drill chuck and a profile mounting seat;

[0007] At least two chuck mounting holes are arranged in the chuck mounting seat, and bearing mounting holes are arranged at the upper and lower ends of the chuck mounting holes. A set of drill chucks is installed in each chuck mounting hole, and both ends of the chuck connecting rod of the drill chuck are installed in the bearing mounting holes at corresponding positions through bearings, and gears that mesh with each other are installed at the top of each drill chuck;

[0008] The profile mounting seat is arranged directly below the clamp mounting seat, and a valve seat mounting position is arranged on the profile mounting seat.

[0009] Based on the above, the drilling installation positions of each drill chuck are located on the same straight line, or arranged in a set shape.

[0010] Based on the above, the lengths of the chuck mounting holes are different, and the heights of the bearing mounting holes of each group are different, so that the installation heights of the drill chucks are different.

[0011] Based on the above, the drill chuck includes a chuck connecting rod and a chuck cap, the chuck connecting rod is fixed to the top end of the chuck cap, and the lower end of the chuck cap is used for installing the drill rod.

[0012] Based on the above, a cavity for accommodating the clamp cap is provided in the clamp mounting seat.

[0013] Based on the above, the rotation directions of two adjacent drill chucks are opposite.

[0014] Based on the above, the top of the chuck mounting seat is a fixed connecting plate, through holes are set at the four corners of the fixed connecting plate, and the fixed connecting plate is installed under the main shaft of the drilling machine through the through holes and long screws. The main shaft of the drilling machine is connected to one of the drill chucks.

[0015] Based on the above, a linear module is arranged in the profile mounting seat, and the linear module is used to drive the valve seat mounting position in the profile mounting seat to move horizontally left and right.

[0016] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0017] By setting up multiple drill chucks and assembling them based on the same chuck mounting base, and transmitting power to each other through gears, the positions and spacings of multiple drill chucks can be pre-set, ensuring that the drilling position and spacing accuracy of the pilot valve seat produced are greatly increased, and the efficiency is greatly improved.

[0018] The combined processing device of the pilot valve seat has the effect of improving the accuracy of the hole spacing through the setting of the chuck mounting seat. Multiple drill bits are integrated through the chuck mounting seat and then the pilot valve seat is processed synchronously. The spacing between the drill bits is the same as the hole spacing required for the installation of the pilot valve, and the size of the drill bit is also the same as the hole diameter required for the installation of the pilot valve. Therefore, all the hole positions required for the installation of a pilot valve can be completed in one processing, which can avoid the accuracy error caused by repeated positioning, and thus the accuracy of the hole spacing can be improved.

A gear 6 is installed above the drill chuck 4, the middle drill bit 5 is right-handed, and the drill bits 5 on both sides are left-handed. The gears 6 on both sides mesh with the middle gear 6 and rotate synchronously. A valve seat semi-finished product 7 is installed inside the profile mounting seat 2. There are three drill bits 5 and they are arranged in a row with the same spacing. The lower ends of the three drill bits 5 have the same height, and the spacing between the three drill bits 5 is the same as the hole spacing that needs to be punched in the valve seat semi-finished product 7. The outer diameter of the drill bit 5 is the same as the hole diameter that needs to be punched in the valve seat semi-finished product 7. The profile mounting seat 2 is installed directly below the chuck mounting seat 1. The valve seat semi-finished product 7 is positioned by pins and fixed inside the profile mounting seat 2 with screws. A linear module 8 is arranged below the profile mounting seat 2. When the linear module 8 is working, it drives the valve seat semi-finished product 7 to move left and right.

[0027] When in use, firstly, a corresponding chuck mounting seat 1 is made according to the hole size and hole spacing required for installing the pilot valve, and the chuck mounting seat 1 is required to be able to integrate all the drill bits 5 for processing these holes, and further all the angular contact bearings 3 are installed in the bearing mounting holes 102, and then all the drill chucks 4 are inserted between the two angular contact bearings 3 from bottom to top, and further gears 6 are installed on all the chuck connecting rods 401, and all the drill chucks 4 are rotated synchronously through the meshing transmission between the gears 6, and further the combined processing device of the pilot valve seat is installed under the drilling machine, and the top of one of the drill chucks 4 is connected to the main shaft of the drilling machine.

The hole positions processed at one time are all the hole positions required for installing a pilot valve. Since the hole positions are processed at one time, the accuracy of the hole spacing is relatively high, and processing multiple hole positions at one time also greatly improves the processing efficiency.
