Description

Technical Field

[0001] This utility model relates to the field of pneumatic clamps, specifically a pneumatic clamp for processing a cover plate of an intelligent control unit. Background Technology

[0002] A smart control unit cover is a panel used to protect and control the control unit. It is typically installed in electronic devices or systems to provide access to and protection for internal components. Smart control unit covers are widely used in various electronic devices and systems, such as industrial control systems, smart homes, and intelligent transportation systems. During processing, smart control unit covers are usually clamped and fixed using pneumatic jigs. Then, the clamped and fixed cover is processed by drilling, edge grinding, and polishing. However, traditional pneumatic jigs used for processing smart control unit covers can only perform a single clamping function and cannot rotate the cover while clamping. This is not conducive to edge grinding and other operations on the cover edges. The limitation of its function makes it difficult for existing pneumatic jigs to achieve efficient and convenient processing.

[0003] To address the aforementioned issues, we propose a pneumatic fixture for machining intelligent control unit cover plates, which improves upon the shortcomings of existing technologies. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a pneumatic clamp for processing intelligent control unit cover plates. In order to solve the above-mentioned technical problem, this utility model provides the following technical solution:

[0005] This utility model discloses a pneumatic fixture for processing a cover plate of an intelligent control unit, including a fixture table. A hanger is mounted on the fixture table. A cover plate clamping mechanism and a cover plate rotating mechanism are respectively mounted on the hanger and the fixture table. The cover plate clamping mechanism includes a hydraulic push rod, an air reservoir, a first cylinder, a pressure rod, a first piston plate, an upper pressure plate, a second piston plate, an air guide pipe, and a first return spring. The hydraulic push rod and the air reservoir are fixed on the hanger. The first cylinder is fixed below the top of the hanger. A retractable pressure rod is inserted into the bottom end of the first cylinder. The inner end of the pressure rod is fixed to the first piston plate. The outer end of the pressure rod is connected to the upper pressure plate via a bearing. The extended end of the hydraulic push rod extends into the air reservoir and is fixed thereon. Piston disc two; the gas storage cylinder and cylinder barrel one are connected by a gas guide pipe one; a return spring one is also sleeved on the pressure rod; the cover plate rotating mechanism includes a rotating column, a lower tray, a gear disc, cylinder barrel two, a push rod, piston disc three, return spring two, a toothed plate and a gas guide pipe two; a rotating column is set on the fixture platform; a lower tray is fixed to the top of the rotating column; a gear disc is sleeved and fixed on the rotating column; cylinder barrel two is mounted and fixed on the fixture platform; a retractable push rod is inserted into cylinder barrel two; piston disc three is fixed to the inner end of the push rod; return spring two is also sleeved on the push rod; a toothed plate is fixed to the outer end of the push rod; the gas storage cylinder and cylinder barrel two are connected by a gas guide pipe two.

[0006] Preferably, the upper pressure plate is located directly above the lower tray.

[0007] Preferably, the rotating column is connected to the fixture table via a bearing.

[0008] Preferably, the teeth on the gear plate mesh with the teeth on the gear disk.

[0009] Preferably, a limiting plate is welded onto the fixture table, and the back of the toothed plate is attached to the limiting plate.

[0010] Preferably, the elastic force of the second reset spring is greater than that of the first reset spring.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] By equipping the fixture table with a cover plate clamping mechanism and a cover plate rotating mechanism, compressed air is delivered to cylinder one using a hydraulic pusher. The compressed air presses down on the upper pressure plate, thus clamping the cover plate to be processed onto the lower tray. Alternatively, compressed air can be pushed into cylinder two using the hydraulic pusher, pushing a toothed plate outwards. The toothed plate rotates a gear disc, which in turn rotates a rotating column and the lower tray, causing the cover plate clamped on the lower tray to rotate. This pneumatic fixture for processing intelligent control unit cover plates adopts a linkage structure design, allowing the cover plate to rotate after clamping, facilitating processes such as grinding the cover plate edges. It is fully functional, meeting the clamping and rotation requirements during intelligent control unit cover plate processing, thus achieving efficient and convenient processing and improving practicality.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example

[0019] like Figure 1-3As shown, a pneumatic fixture for processing a cover plate of an intelligent control unit includes a fixture table 1, a hanger 2 mounted on the fixture table 1, and a cover plate clamping mechanism and a cover plate rotating mechanism respectively mounted on the hanger 2 and the fixture table 1. The cover plate clamping mechanism includes a hydraulic push rod 3, an air storage cylinder 4, a cylinder barrel 5, a pressure rod 6, a piston disc 7, an upper pressure plate 9, a second piston disc 10, an air guide pipe 11, and a return spring 12. The hydraulic push rod 3 and the air storage cylinder 4 are fixed on the hanger 2. A cylinder 5 is fixed at the bottom of the top. A retractable pressure rod 6 is inserted into the bottom of the cylinder 5. A piston disc 7 is fixed to the inner end of the pressure rod 6. An upper pressure plate 9 is connected to the outer end of the pressure rod 6 through a bearing 8. The protruding end of the hydraulic push rod 3 extends into the air storage cylinder 4 and is fixed with a piston disc 10. The air storage cylinder 4 and the cylinder 5 are connected through an air guide pipe 11. A return spring 12 is also fitted on the pressure rod 6. The cover plate rotation mechanism includes a rotating column 14 and a lower tray 15. The fixture includes a gear disc 16, a second cylinder 17, a push rod 18, a third piston disc 19, a second return spring 20, a gear plate 21, and a second air guide pipe 22. A rotating column 14 is mounted on the fixture table 1, with a lower tray 15 fixed to the top of the rotating column 14. A gear disc 16 is fitted and fixed on the rotating column 14. A second cylinder 17 is mounted and fixed on the fixture table 1, with a retractable push rod 18 inserted inside the second cylinder 17. A third piston disc 19 is fixed to the inner end of the push rod 18. A second cylinder 19 is also fitted on the push rod 18. The device includes a return spring 20, a toothed plate 21 fixed to the outer end of the push rod 18, and a gas storage cylinder 4 connected to the cylinder barrel 17 via an air guide pipe 22. This forms an integrated pneumatic clamping structure for processing the cover plate of the intelligent control unit. It adopts a linkage structure design, allowing the cover plate to rotate after clamping, which facilitates the grinding and other processing of the cover plate edges. It is fully functional and can meet the clamping and rotation requirements during the processing of the cover plate of the intelligent control unit, thereby achieving efficient and convenient processing.

[0020] In this embodiment, the upper pressure plate 9 is located directly above the lower tray 15, ensuring that the cover plate is sandwiched between the two.

[0021] In this embodiment, the rotating column 14 is connected to the fixture table 1 via the bearing 13, allowing the rotating column 14 to rotate, thereby allowing the clamped cover plate to rotate.

[0022] In this embodiment, the teeth on the toothed plate 21 mesh with the teeth on the gear disk 16, and the toothed plate 21 drives the gear disk 16 to rotate, realizing a linkage structure design that allows the cover plate to rotate after it is clamped.

[0023] In this embodiment, a limiting plate 23 is also welded onto the fixture table 1, and the back of the toothed plate 21 is attached to the limiting plate 23 to ensure that the toothed plate 21 can be pulled tightly against the gear disk 16.

[0024] In this embodiment, the elastic force of the second reset spring 20 is greater than that of the first reset spring 12, which can realize the function of pressing and fixing before rotation, and has multiple functions to meet the processing requirements.

[0025] The principle and advantages of this utility model are as follows: The controller on the hanger 2 is connected to the hydraulic push rod 3, and the controller is connected to a power source to supply power to the clamp. Air at a certain pressure is injected into the air storage cylinder 4 through the air filling pipe, and then... Figure 2 As shown, place the intelligent control unit cover plate to be processed on the lower tray 15, activate the hydraulic push rod 3 to extend it, and push the compressed air inside it into the cylinder 5 through the air guide pipe 11, and into the cylinder 17 through the air guide pipe 22. Since the elastic force of the return spring 20 is greater than that of the return spring 12, the compressed air will first compress the return spring 12, and the pressure rod 6 will extend, bringing the upper pressure plate 9 down, thereby pressing the cover plate firmly onto the lower tray 15. At this time, the worker can hold the edge grinding tool and place the grinding disc against the edge of the cover plate. When the pressure rod 6 can no longer extend, as... Figure 3 As shown, the compressed air is forced into cylinder 17, compressing the return spring 20. The push rod 18 is pushed out, and the toothed plate 21 is pushed forward along the gear disk 16, causing the gear disk 16 to rotate. The gear disk 16 then causes the rotating column 14 to rotate, thus rotating the pressed cover plate. The worker can then grind the edge of the cover plate. The rotation of the cover plate can improve the grinding speed and efficiency. Since the length of the toothed plate 21 is greater than the diameter of the gear disk 16, it can rotate the cover plate 360°, ensuring that the grinding disc can grind all the edges of the cover plate. When the processing is completed and the cover plate is removed, the hydraulic push rod 3 retracts, the return spring 20 retracts first, and then the return spring 12 retracts. The compressed air flows back to the air storage cylinder 4, the push rod 18 retracts into cylinder 17, the pressure rod 6 retracts into cylinder 5, the upper pressure plate 9 rises, and no longer presses down to clamp the cover plate, so the processed cover plate can be removed.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
