Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguisher processing equipment, and particularly relates to a composite processing device for fire extinguisher valves. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool containing chemical substances for extinguishing fires. It is one of the common fire-fighting equipment, usually stored in public places or where fires may occur. Different types of fire extinguishers are filled with different components and are designed specifically for different fire causes. However, whether it is a portable, trolley-mounted, backpack-mounted, or gas cylinder type, pressure storage type, chemical reaction type fire extinguisher that involves spraying contents for fire extinguishing, generally it will have a valve body as shown in Figure 1 and Figure 2 The valve body is provided with a hanger hole and a rivet hole.

[0003] When the existing valve body is processed, generally it is first formed by die casting, and then drilling and grooving operations are carried out. The original flat head also needs to be subjected to end face leveling work to remove casting defects for better cooperation with the gasket. The existing processing method is to design processing procedures and transfer the workpiece to different equipment for processing in sequence. Due to the different positions and directions of each processing, and the valve body is not a regular shape, since it needs to be fixed on different equipment for processing different positions, corresponding fixture jigs need to be designed specifically, resulting in a high installation cost. At the same time, the stacking and transfer of workpieces also consume a lot of man-hours, increasing the production cost, and there is room for further improvement. Summary of the Invention

[0028] Referring to Figures 3 - 5 , an embodiment of the present invention provides a composite processing device for a fire extinguisher valve, including a workbench 1 and a middle groove 2. A middle groove 2 is provided in the middle of the workbench 1. Both sides inside the middle groove 2 are fixedly connected with fixed slide bars 3. Above the inside of the middle groove 2, a sliding seat 4 is slidably connected through two fixed slide bars 3. Above the sliding seat 4, a fixture fixing table 7 is fixedly connected. On one side above the middle groove 2, a hydraulic fixed seat 5 is fixedly connected. In the middle of the side of the hydraulic fixed seat 5 away from the sliding seat 4, a driving hydraulic cylinder 6 is fixedly connected. The output end of the driving hydraulic cylinder 6 passes through the hydraulic fixed seat 5 and is fixedly connected with the fixture fixing table 7. On the side of the fixture fixing table 7 close to the hydraulic fixed seat 5, a clamping cylinder 9 is fixedly connected. Above the fixture fixing table 7, on the side close to the clamping cylinder 9, a sliding clamping seat 10 is slidably connected. On the side of the fixture fixing table 7 above, away from the clamping cylinder 9, a fixed clamping seat 8 is fixedly connected. In the middle of one end of the fixed clamping seat 8, a rivet hole punching groove 11 is opened. On the side of the sliding clamping seat 10 away from the fixed clamping seat 8, a hanger hole processing groove 12 is opened. Above the sliding clamping seat 10, a saw blade accommodating groove 13 is opened;

[0029] On one side of the workbench 1, away from the rivet hole punching groove 11, a first main spindle box 14 is fixedly connected. The spindle output end of the first main spindle box 14 is fixedly connected with a grooving saw blade 15. At one end of the workbench 1, away from the hydraulic fixing seat 5, a second main spindle box 16 is fixedly connected. The spindle output end of the second main spindle box 16 is fixedly connected with a rivet hole drill bit 17. At one end of the workbench 1, away from the first main spindle box 14, two third main spindle boxes 19 are fixedly connected. The first main spindle box 14, the second main spindle box 16 and the third main spindle boxes 19 are all electric main spindle boxes. The output ends of the two third main spindle boxes 19 are provided with telescopic rotating shafts 20. The telescopic rotating shaft 20 includes a hydraulic telescopic sleeve and an electric main spindle. The inner sleeve of the hydraulic telescopic sleeve is telescopically connected with the electric main spindle through a sliding key. At one end of the two telescopic rotating shafts 20, close to the fixed clamping seat 8, a face milling cutter 21 and a hanger hole drill bit 22 are respectively fixedly connected. During processing, driven by the driving hydraulic cylinder 6, the workpiece moves through different corresponding processing stations through the fixture.

The end processing position of the rivet hole drill bit 17 is arranged within the buffer area of the buffer hydraulic cylinder 18. The speed of the workpiece can be buffered before the driving hydraulic cylinder 6 enters the maximum stroke, reducing the movement speed of the workpiece, increasing the processing time of the grooving saw blade 15 and the rivet hole, reducing the depth of cut, and further reducing the risk of tool collision. The processing position of the face milling cutter 21 corresponds to the maximum moving stroke position of the fixed clamping seat 8. The processing position of the hanger hole drill bit 22 corresponds to the minimum forming position of the fixed clamping seat 8. By arranging the processing stations at the maximum and minimum strokes of the driving hydraulic cylinder 6 as much as possible, sufficient processing accuracy can be achieved only through hydraulic buffering and mechanical limiting methods, without the need for a high-precision lead screw structure and the corresponding servo to precisely control the processing position, reducing the production cost.

[0031] Working principle: When the present invention is working, during processing, driven by the driving hydraulic cylinder 6, the workpiece moves through different processing stations through the fixture. Through the integrated arrangement of the processing stations, the hanger hole, grooving, rivet hole and flat head end face of the workpiece are subjected to one-time composite processing in sequence. And a buffer hydraulic cylinder 18 is arranged opposite to the driving hydraulic cylinder 6, which can buffer the speed of the workpiece before the driving hydraulic cylinder 6 enters the maximum stroke, reducing the movement speed of the workpiece, increasing the processing time of the grooving saw blade 15 and the rivet hole, reducing the depth of cut, and further reducing the risk of tool collision.
