Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnetic pilot valve core assembly technology, and in particular to an inverted valve core assembly device. Background Technology
[0002] Hydraulic supports are coal mining face support equipment that uses high-pressure liquid as power and is composed of hydraulic components and metal structural parts. Its core functions are to support the roof, move the support, push the conveyor, and isolate the goaf. It is a key piece of equipment for the mechanization of fully mechanized coal mining.
[0003] During hydraulic support maintenance, a single hydraulic support has multiple electro-hydraulic solenoid pilot valves, resulting in a large number of these valves requiring maintenance across multiple hydraulic supports. The lack of an effective assembly device for the solenoid pilot valve core assembly leads to a heavy workload. The complete spring sleeve of the solenoid pilot valve core contains a spring and a ceramic ball. During assembly, the complete spring sleeve must be assembled from bottom to top. In existing technology, this is done manually by holding the solenoid pilot valve with one hand, valve core assembly port facing down, and using the other hand to hold an Allen wrench and the complete spring sleeve upwards, tightening the spring sleeve towards the valve core assembly port. This process is slow in terms of alignment and tightening, resulting in low assembly efficiency. Therefore, this invention proposes an inverted valve core assembly device to solve the above problems.

When assembling the valve core, the assembly port of the electromagnetic pilot valve core is placed downwards in the process groove of the valve seat of the self-resetting mechanism, which can automatically align it with the complete spring sleeve. The electromagnetic pilot valve can be automatically assembled by simply pressing it down and simultaneously starting the power pneumatic screwdriver. The accuracy and efficiency of valve core assembly operations can be effectively improved.

[0014] To enhance understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are for illustrative purposes only and do not constitute a limitation on the scope of protection of this utility model.
[0015] according to Figure 1-5 As shown in the figure, this embodiment proposes an inverted valve core assembly device, including an operating table 1, a self-resetting mechanism, a locking mechanism 2, a power fixing mechanism 3, and a power air screwdriver 4. The self-resetting mechanism includes a valve seat 5 and a reset plate 6. The reset plate 6 is set on the top of the operating table 1. The locking mechanism 2 has two sets. The reset plate 6 is fixed to the operating table 1 by the two sets of locking mechanisms 2. The valve seat 5 is provided above the reset plate 6. The valve seat 5 and the reset plate 6 are connected by an elastic component 7. The valve seat 5 has a process groove 8 on its top. The reset plate 6 has a positioning groove 9. The power air screwdriver 4 is provided below the reset plate 6. The power air screwdriver 4 is assembled with the reset plate 6 by the power fixing mechanism 3, and the power air screwdriver 4 is connected to an external air compressor air source.
[0016] When using the inverted valve core assembly device of this utility model, the valve core of the electromagnetic pilot valve is placed into the process groove 8 on the valve seat 5 with the assembly port facing down (in this utility model, the shape and size of the process groove 8 are set according to the shape of the valve core). Then, the complete spring sleeve is installed on the power screwdriver 4 with the opening facing up. Then, by pressing down the valve seat 5, the valve seat 5 and the valve core move down as a whole under the action of the elastic component 7, so that the valve core enters the assembly position aligned with the complete spring sleeve. Then, the power screwdriver 4 is started to complete the alignment and screwing assembly of the valve core.
[0017] The elastic component 7 includes a spring 10, a first screw 11, and nuts 12. The valve seat 5 has screw holes on both sides of its top, with the first screw 11 installed in each hole. Two nuts 12 at the lower end of the first screw 11 are locked to the reset plate 6. A spring 10 is fitted around the outside of the first screw 11 between the valve seat 5 and the reset plate 6. The upper end of the spring 10 is connected to the outer wall of the first screw 11, and the lower end of the spring 10 is connected to the top of one of the nuts 12 above it. When the valve seat 5 is pressed down, the spring 10 is compressed, causing the valve seat 5 to move downwards as a whole.
[0018] The locking mechanism 2 includes a first locking plate 201, a second locking plate 202, a second screw 203, and a third screw 204. The first locking plate 201 is connected to the reset plate 6 and the second locking plate 202 at both ends via the second screw 203, respectively. The second locking plate 202 is connected to the operating table 1 via the third screw 204. This locking mechanism securely connects the reset plate 6 to the operating table 1, providing high tightness. A stably installed reset plate 6 also helps improve the valve core assembly accuracy.
[0019] The power fixing mechanism 3 includes a power fixing plate 301 and a clamping assembly. The power fixing plate 301 is fixed to the bottom of the reset plate 6 by mounting bolts. Multiple sets of clamping assemblies are provided, and the power screwdriver 4 is fixed to the power fixing plate 301 by these multiple sets of clamping assemblies. The clamping assembly includes a clamping plate 302 and a fourth screw 303. The clamping plate 302 has a positioning arc groove 304 with a diameter adapted to the outer diameter of the power screwdriver 4. The clamping plate 302 has fourth screws 303 at both ends, one end of which is connected to the power fixing plate 301. To fix the power screwdriver 4, it is inserted into the positioning arc groove 304 on the clamping plate 302, and then the clamping plate 302 is connected to the power fixing plate 301 using the fourth screw 303.
[0020] The process groove 8 and the positioning groove 9 are matched in position, and the centers of the process groove 8, the positioning groove 9, and the positioning arc groove 304 are located on the same vertical line. This arrangement achieves precise alignment and positioning of the valve core and the complete spring sleeve.
[0021] The inverted valve core assembly device of this utility model can place the complete spring sleeve on the power air screwdriver 4. The spring and ceramic ball inside the complete spring sleeve are facing upwards and will not fall off. When assembling the valve core, by placing the assembly port of the electromagnetic pilot valve core downwards in the process groove 8 of the valve seat 5 of the self-resetting mechanism, it can be automatically positioned and aligned with the complete spring sleeve. The electromagnetic pilot valve can be automatically assembled by simply pressing down and placing it and simultaneously starting the power air screwdriver 4. The accuracy and efficiency of valve core assembly can be effectively improved, and the consumption of manual labor can be reduced.
