Description

Technical Field

[0001] This invention relates to the field of air compressor machining, and in particular to a device for machining air compressor pistons. Background Technology

[0002] Pistons operate under continuous variable loads in high-temperature, high-pressure, and highly corrosive environments. Therefore, corresponding structures and processing techniques are required during manufacturing to meet their specific working conditions.

[0003] Existing air compressor piston rod positioning fixtures generally have a relatively simple structure, typically using two sets of clamps to hold and fix the piston rod. When other surfaces of the piston rod need to be machined, the piston rod needs to be disassembled and repositioned, which is quite troublesome. Furthermore, during installation, disassembly, or machining, the distance between the two sets of clamps is prone to change, which can lead to the piston rod slipping between the two sets of clamps and falling onto the machine or the ground, causing damage. Summary of the Invention

[0004] The purpose of this invention is to provide a device for machining air compressor pistons.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

A spring is sleeved on the T-shaped rod above the mounting seat. The bottom end of the T-shaped rod is connected to a horizontal plate. A support seat is provided at the end of the horizontal plate, and an arc-shaped notch is provided on the top of the support seat.

[0007] Preferably, a groove is provided around the back of the disc, the groove is coaxial with the rotating shaft, and a slide rod is provided on the vertical plate extending into the top opening of the groove. The slide rod is located above the mounting base between the two sets of T-shaped rods, and the mounting base is provided with a circular hole for the vertical end of the T-shaped rod to pass through.

[0008] Preferably, the machine tool is provided with a limiting rod that passes through the through holes on two sets of vertical plates. The vertical plates are provided with screw holes that are screwed to the positive and negative lead screws. The two ends of the positive and negative lead screws are fixed to the corresponding side walls of the machine tool by bearings III.

[0009] Preferably, the support base is located below the disc, wherein two sets of support bases are located between two sets of discs, and the two sets of discs are located between two sets of vertical plates.

[0010] Preferably, the recycling mechanism includes a strip-shaped base with a circular cross-section mounting cavity inside.

[0018] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] An air compressor piston processing device includes a machine base 1. The machine base 1 has strip-shaped openings 2 on both sides of its top wall. A recovery mechanism 22 is located on the top of the machine base 1 between two sets of strip-shaped openings 2. A vertical plate 3 is located inside each strip-shaped opening 2. A forward and reverse lead screw 4, passing through the vertical plate 3 and driven by a motor I5, is located inside the machine base 1. A rotating shaft 6 is fixed to the top of the vertical plate 3 via a bearing I7. A disc 8 and a gear I9 are respectively located at both ends of the rotating shaft 6. A gear II10 meshes with the gear I9 and is driven by a motor II11.

[0020] The back of the disc 8 is also provided with a mounting base 12 for the rotating shaft 6 to pass through. The mounting base 12 is provided with a bearing II13 that is sleeved on the rotating shaft 6. The top of the mounting base 12 on both sides of the bearing II13 is provided with a T-shaped rod 14 that penetrates its side wall. A spring 15 is sleeved on the T-shaped rod 14 above the mounting base 12. The bottom end of the T-shaped rod 14 is connected to the horizontal plate 16. The end of the horizontal plate 16 is provided with a support base 17. The top of the support base 17 is provided with an arc-shaped notch 18.

[0021] A groove 19 is provided around the back of the disc 8. The groove 19 is coaxial with the rotating shaft 6. A sliding rod 20 is provided on the vertical plate 3, extending into the top opening of the groove 19. The sliding rod 20 is located above the mounting base 12 between the two sets of T-shaped rods 14. The mounting base 12 is provided with a round hole for the vertical end of the T-shaped rod 14 to pass through.

[0022] In this embodiment, the machine base 1 is provided with a limiting rod 21 that passes through the through holes on two sets of vertical plates 3. The vertical plates 3 are provided with screw holes that are screwed to the positive and negative lead screws 4. The two ends of the positive and negative lead screws 4 are fixed in the corresponding side wall of the machine base 1 by bearings III.

[0023] like Figure 1 ,2 As shown, the support base 17 is located below the disc 8, with two sets of support bases 17 located between two sets of discs 8, and the two sets of discs 8 located between two sets of vertical plates 3.

[0024] The recycling mechanism 22 includes a strip-shaped seat 221, which has a circular cross-section mounting cavity 222. The top of the strip-shaped seat 221 has a feed opening 223 communicating with the mounting cavity 222. The bottom of the mounting cavity 222 has a collection groove 224 communicating with it. The mounting cavity 222 also has a drive shaft 225 coaxially arranged with it. The drive shaft 225 is driven by a motor III 226. The outer wall of the drive shaft 225 is radially arranged with multiple sets of magnetic plates 227 made of electromagnet material. The bottom wall of the collection groove 224 is inclined. The bottom of the collection groove 224 is also evenly arranged with multiple sets of grid plates 228. The side wall of the strip-shaped seat 221 between adjacent sets of grid plates 228 is provided with an inlet and outlet communicating with the collection groove 224. The inlet and outlet are arranged on the same side as the bottom of the bottom wall of the collection groove 224. The inlet and outlet are provided with a door 229.

[0025] The method of using the present invention is as follows: The two ends of the piston rod are placed into the arc-shaped notches 18 in the corresponding support seats 17 for support. At this time, under the pressure of the piston rod's gravity, it drives the T-shaped rod 14 to slide downward in the round hole on the mounting seat 12 through the support seat 17 and the horizontal plate 16, while compressing the spring 15. At this time, the motor I5 drives the positive and negative lead screws 4 to rotate in the screw holes on the vertical plate 3, thereby driving the vertical plate 3 to slide in the strip opening 2. At this time, the vertical plate 3 drives the disc 8 to move through the rotating shaft 6, thereby reducing the distance between the two sets of discs 8 to clamp and fix the two ends of the piston rod. During this process, the rotating shaft 6 also moves through the mounting seat 12, the T-shaped rod 14, the horizontal plate 16 and the support seat 17 to drive the arc-shaped notches 18 to slide at the bottom of the piston rod end.

[0026] When different end faces of the piston need to be machined, the motor II11 drives gears II10 and I9 to rotate the shaft 6 on the bearing I7. The rotating shaft 6 drives the disc 8 and the product clamped and fixed by the two sets of discs 8 to rotate. At this time, the product rotates within the arc-shaped notch 18 without being driven to rotate with it. When the disc 8 rotates, it drives the slide groove 19 to slide on the end of the slide rod 20. At this time, the slide rod 20 does not affect the rotation of the disc 8, and it can also support and fix the suspended disc 8, preventing the problem of insufficient stability caused by a large area of ​​suspension. During the rotation of the shaft 6, it drives the bearing II13. The inner ring rotates on its balls, and under the pull of gravity of components such as support seat 17, horizontal plate 16 and T-shaped rod 14, the mounting seat 12 will not rotate with the rotating shaft 6 and the product, so that the support seat 17 is always located at the bottom of the product to provide a certain support. In this way, the different end faces of the piston rod are switched to face upward, which makes it easier for people to process the entire outer surface of the piston rod. When installing, disassembling or rotating the product, under the support of T-shaped rod 14, spring 15, horizontal plate 16, support seat 17 and arc notch 18, the product will not slip between the two sets of discs 8 and fall onto the machine base 1 or the ground and get injured.

[0027] During processing, metal scraps fall into the feed opening 223 directly below the magnetic plate 227, eventually entering the mounting cavity 222 and coming into contact with the energized magnetic plate 227 located above. The scraps are magnetically attracted to the magnetic plate 227. When there are many scraps on the surface of the upper magnetic plate 227, the motor III 226 drives the magnetic plate 227 to rotate below the mounting cavity 222 via the drive shaft 225. At the same time, it drives the idle magnetic plate 227 below to move upward and become energized to attract the scraps that fall into the mounting cavity 222. When the magnetic plate 227 with the scraps is rotated to the bottom of the mounting cavity 222, the power to the magnetic plate 227 is turned off, causing the scraps below its surface to fall and slide into the collection tank 224. The scraps that accumulate in the collection tank 224 can be removed by opening the corresponding switch door 229 through the inlet and outlet, thus recycling and collecting the metal scraps.

[0028] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
