Description

Technical Field

[0001] This utility model relates to the field of control box processing technology, and specifically to a control box processing device. Background Technology

[0002] The control panel, also known as the "operation panel," is a control panel for operating machines and devices. It uses command switches, buttons, or handles to operate the car. Only in the inter-floor operation mode can the control panel for operating the car in the waiting hall be called the landing control panel. The control panel needs to be punched to facilitate the installation of buttons, and the control panel is usually made of sheet metal.

[0003] Existing technology, such as the utility model patent with publication number CN29639254U, discloses a punching machine for chassis sheet metal parts, including a worktable, a punching mechanism, and a positioning mechanism. The worktable has a mounting bracket fixedly connected to its upper end. The punching mechanism includes a connecting platform, a sliding sleeve, a punching platform, punching cutters, locking holes, and punching clearance openings. The connecting platform is slidably connected to the outer surface of the support column of the mounting bracket through the sliding sleeve. The punching platform is slidably connected to the bottom end of the connecting platform through a trapezoidal groove. Punching cutters are evenly arranged at the bottom end of the punching platform. The upper end of the connecting platform has a locking hole. The punching clearance openings are evenly arranged at the upper end of the worktable. The positioning mechanism is located inside the punching mechanism. This punching machine for chassis sheet metal parts collects iron filings generated during punching of chassis sheet metal parts by simultaneously pressing down and rising the dust collection groove. By pressing the pressing block, it avoids the phenomenon that vibration of the chassis sheet metal parts during punching will cause small displacements that affect the accuracy of punching the chassis sheet metal parts.

[0004] In the prior art, when punching a single type of control box, a punching plate and punching cutters distributed on the punching plate are used to complete the punching in one go. However, the punching plate is usually fixed with bolts, which is inconvenient to replace and has low practicality.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a control box processing device that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: a control box processing device, comprising: a worktable, a punching plate, and a fixing mechanism for facilitating the fixing of the punching plate;

[0008] The fixing mechanism includes: a positioning rod with a fixing groove, the inner wall of which is in movable contact with a ball bearing; the ball bearing is movably installed in a fixing cylinder, an airbag is fixedly installed on the top of the inner wall of the fixing cylinder, a push block is fixedly connected to the airbag; and a valve is fixedly connected to the airbag.

[0009] Furthermore, the positioning rod is fixedly installed on the perforated plate, and the positioning rod passes through the lifting plate.

[0010] Furthermore, a limiting block is fixedly installed in the fixed cylinder, the limiting block is provided with a limiting groove, and the inner wall of the limiting groove is provided with a through hole aligned with the fixed groove.

[0011] Furthermore, the push block is slidably installed in the fixed cylinder, and the bottom of the push block is provided with a tapered surface; the positioning rod slides through the push block.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a control box processing device in which a positioning rod is inserted into a fixed cylinder and the air bladder is squeezed, causing the edge of the air bladder to bulge and drive the push block to slide down. The conical surface on the push block pushes the ball bearing, which moves along the limiting groove and moves to the inner wall of the fixed groove, preventing the positioning rod from sliding up and down and fixing the position of the positioning rod. This fixes the perforated plate on the lifting plate. When the valve is opened, the air in the air bladder is discharged, and the perforated plate drives the limiting rod to disengage from the fixed cylinder, making it easy to replace the perforated plate.

[0023] like Figures 1 to 6 As shown, the present invention provides a control box processing device, comprising: a worktable 1, a punch plate 13, a fixing mechanism for fixing the punch plate 13, and a mounting mechanism for mounting the processing table 15.

[0024] A frame 3 is fixedly installed on the workbench 1. A guide block 12 is fixedly installed inside the workbench 1. The bottom of the inclined surface of the guide block 12 is aligned with the slag discharge port 11. The slag discharge port 11 is fixedly installed on the workbench 1. Clamping parts 2 are fixedly installed on both sides of the workbench 1. A hydraulic cylinder 4 is fixedly installed on the frame 3. The piston rod of the hydraulic cylinder 4 is fixedly connected to the lifting plate 5. The lifting plate 5 is slidably installed on the frame 3. The lifting plate 5 is provided with positioning holes and limiting holes. A limiting rod 6 is slidably installed in the limiting holes. A pressing plate 8 is fixedly connected to the limiting rod 6. A spring 7 is fixedly installed between the pressing plate 8 and the lifting plate 5. The spring 7 is sleeved on the limiting rod 6.

[0025] The fixing mechanism includes: a positioning rod 24, which is fixedly installed on the perforated plate 13 and passes through a positioning hole on the lifting plate 5; a punching cutter 14 is fixedly installed on the perforated plate 13; a fixing groove is provided on the positioning rod 24, and the inner wall of the fixing groove is in movable contact with the ball 25; the ball 25 is movably installed in the fixing cylinder 9, and a limiting block 26 is fixedly installed in the fixing cylinder 9. The limiting block 26 is conical and has a through groove through which the positioning rod 24 can pass; the limiting block 26 has symmetrical limiting grooves, and the inner wall of the limiting groove has a through hole aligned with the fixing groove. The diameter of the through hole is smaller than the diameter of the ball 25, and the ball 25 is positioned... An airbag 23 is fixedly installed on the top of the inner wall of the fixed cylinder 9, and a push block 21 is fixedly connected to the airbag 23; the top of the limiting block 26 is a conical surface; the fixed cylinder 9 is fixedly installed on the lifting plate 5, and the fixed cylinder 9 is aligned with the positioning hole; the push block 21 is slidably installed in the fixed cylinder 9, and the bottom of the push block 21 is provided with a conical surface, which is located on the inner side of the push block 21; the gap between the limiting block 26 and the push block 21 is smaller than the diameter of the ball 25, thus limiting the ball 25 in the limiting groove; the positioning rod 24 slides and passes through the push block 21; a valve 22 is fixedly connected to the airbag 23; the valve 22 is fixed and passes through the top of the fixed cylinder 9.

[0026] The positioning rod 24 is inserted into the fixed cylinder 9 and the airbag 23 is squeezed, causing the edge of the airbag 23 to bulge and drive the push block 21 to slide down. The conical surface on the push block 21 pushes the ball 25, which moves in the limiting groove. When the ball 25 contacts the fixing groove on the positioning rod 24, it prevents the positioning rod 24 from sliding up and down, thus fixing the position of the positioning rod 24 and fixing the punch plate 13 on the lifting plate 5. The valve 22 is opened, and the air in the airbag 23 is discharged. The punch plate 13 drives the limiting rod 6 to disengage from the fixed cylinder 9, making it easy to replace the punch plate 13 and the punching cutter 14. In the prior art, the punch plate 13 is used when punching a single type of control box. The punching cutters 14 distributed on the punch plate 13 complete the punching in one go. However, the punch plate 13 is usually fixed with bolts, which is inconvenient to replace and has low practicality. Therefore, a fixing mechanism is set up, and the fixing of the punch plate 13 is controlled by the valve 22 on the air bag 23. When disassembling, the valve 22 is opened, and the weight of the punch plate 13 pulls the positioning rod 24. The edge of the fixing groove on the positioning rod 24 pushes the ball 25. The ball 25 pushes the push block 21, causing the push block 21 to rise. The ball 25 disengages from the fixing groove, allowing the positioning rod 24 to slide up and down and disengage from the fixing cylinder 9, making it easy to remove the punch plate 13. The weight of the push block 21 pulls the air bag 23 to unfold, and then the valve 22 is closed.

[0027] The mounting mechanism includes: a motor 17, which is fixedly mounted on a fixed frame 16, which is fixedly mounted on a worktable 1; the output shaft of the motor 17 is fixedly connected to a threaded rod 18, a movable plate is threadedly mounted on the threaded rod 18, and the other end of the movable plate is slidably mounted on a fixed rod, which is fixedly mounted in another fixed frame 16; a second limiting block 20 is fixedly mounted on the movable plate, and a processing table 15 is movably mounted on the movable plate, with a second limiting groove on the processing table 15; the second limiting block 20 is slidably mounted in the second limiting groove; a positioning plate is fixedly mounted on the processing table 15; a first limiting block 19 is fixedly mounted on the processing table 15, and a first limiting groove is provided in the opening on the worktable 1, with the first limiting block 19 slidably mounted in the first limiting groove; the processing table 15 is aligned with a changing table 10, which is fixedly mounted on the worktable 1; and a clearance hole is provided on the processing table 15, which is aligned with a punching tool 14.

[0028] Working principle:

[0029] During installation, the corresponding processing table 15 and mounting plate are placed on the replacement table 10, and the second limiting block 20 is inserted into the second limiting groove, and the punching cutter 14 is inserted into the clearance hole. The motor 17 is started, and the output shaft of the motor 17 drives the threaded rod 18 to rotate, causing the moving plate to move the processing table 15. When the first limiting block 19 on the processing table 15 is inserted into the first limiting groove, the hydraulic cylinder 4 is started. The piston rod of the hydraulic cylinder 4 drives the lifting plate 5 to descend. When the lifting plate 5 descends close to the punching plate 13, the positioning rod 24 is inserted into the fixed cylinder 9 and squeezes the air bag 23, causing the edge of the air bag 23 to bulge and drive the pushing block 21 to slide down. The conical surface on the pushing block 21 pushes the ball 25 to slide in the limiting groove. When the ball 25 contacts the inner wall of the fixed groove on the positioning rod 24, the surface of the ball 25 is tightly against the inner wall of the fixed groove. Contact is prevented, thus preventing the positioning rod 24 from sliding up and down and fixing its position, so that the punch plate 13 is fixed on the lifting plate 5. During disassembly, the lifting plate 5 descends, allowing the punching cutter 14 to be inserted into the clearance hole. The valve 22 is opened, and the lifting plate rises. The weight of the punch plate 13 pulls the positioning rod 24, and the edge of the fixing groove on the positioning rod 24 pushes the ball 25. The ball 25 pushes the pushing block 21, causing the pushing block 21 to rise. The ball 25 disengages from the fixing groove, allowing the positioning rod 24 to slide up and down and disengage from the fixing cylinder 9. The positioning rod 24 is driven by the punch plate 13 and disengages from the fixing cylinder 9, making it easy to remove the punch plate 13. The weight of the pushing block 21 pulls the airbag 23 to unfold, and the valve 22 is closed to seal the airbag 23, facilitating the replacement of the punch plate 13 and the punching cutter 14, thus improving the practicality of the device.
