Description

Technical Field

[0001] This utility model relates to the field of cylinder processing technology, specifically a drilling device for cylinder processing. Background Technology

[0002] With social development and technological progress, people's living standards have gradually improved. The application of cylinders has been involved in all aspects of industrial production. When processing cylinders, it is necessary to drill holes on the upper surface edge of the cylinder so that the cylinder can be matched with a suitable cap in subsequent processing. The existing method of drilling cylinders is manual support processing, which is prone to inaccurate drilling position, damage to the cylinder itself, increase the cost of drilling cylinders, and require a lot of human resources, thus reducing the work efficiency of drilling processing.

[0003] According to announcement number CN 213080138 U, a drilling device for simple body processing relates to the field of simple body processing technology. It solves the technical problems of existing simple body drilling processing methods that rely on manual support, which easily leads to inaccurate drilling positions, damage to the simple body itself, increased drilling costs, and the need for a large amount of manpower, thus reducing the efficiency of drilling processing. The device includes a base, on which an L-shaped bracket is fixedly installed. A hydraulic cylinder is fixedly installed on the lower wall of the horizontal end of the L-shaped bracket, and a first motor is fixedly installed on the telescopic end of the hydraulic cylinder.

[0004] This device uses a hydraulic cylinder and a first motor to achieve automatic lifting and drilling, eliminating manual labor and improving drilling efficiency. A clamping device uses three jaws to center and fix the cylinder to be processed, making it more secure during drilling. A shock-absorbing device reduces the impact of vibration on the drilling process, improving the stability of the drilling equipment. However, once the cylinder is fixed, it cannot rotate, therefore it cannot drill holes at different positions on the cylinder. Utility Model Content

[0010] Preferably, the second fixing frame has a hole on the right side that matches the first guide rod, and the surface of the first guide rod passes through and slides left and right in the hole. By sliding the first guide rod left and right in the hole, the cylinder held by the first clamping plate and the second clamping plate can be rotated more stably.

[0012] Preferably, the output end of the first servo motor is fixedly connected to the right end of the bidirectional lead screw, and a hole matching the limiting rod is opened on the left side of the first hinge frame near the bottom. The first hinge frame is slidably connected to the surface of the limiting rod through the hole. The limiting rod limits the two first hinge frames, so that the two first hinge frames move towards each other as the bidirectional lead screw rotates.

[0013] Preferably, the top of the base has a hole that matches the first guide rod, and the surface of the first guide rod is penetrated and slidably connected to the hole. The four first guide rods can support the lifting seat, making the lifting seat move up and down more stably.

[0017] The drilling device for cylinder machining includes a lifting and rotating mechanism. The lifting component, driven by a first servo motor, rotates a bidirectional lead screw, causing the symmetrical first hinged frames to move towards each other under the control of a limit rod. This, in turn, drives the second hinged frame and the lifting seat to move stably up and down via the hinge rod. This design allows for rapid adjustment of the cylinder height to adapt to different processing needs, significantly improving work efficiency compared to traditional manual adjustment. Regarding the rotating component, a second servo motor drives a worm gear to rotate, meshing with a worm wheel, thereby driving the first rotating shaft and the first clamping plate to rotate. Simultaneously, a cylinder pushes a moving plate and the second clamping plate closer to or further away from the first clamping plate, facilitating the clamping and positioning of the cylinder. Furthermore, during rotation, the first guide rod slides within the hole of the second fixed frame, ensuring the stability of the cylinder rotation and enabling drilling at different positions on the cylinder.

[0018] This drilling device for cylinder machining features a highly flexible drilling mechanism. The sliding sleeve within the rectangular frame can slide left and right, driven by a moving frame. A third servo motor drives a third rotating shaft and gears to mesh with a rack, enabling precise movement of the moving frame along the rectangular frame. The lateral position of the drill bit can be flexibly adjusted according to different positions of the cylinder and machining requirements. A fourth servo motor drives the drill bit to rotate at high speed for drilling. This precise position adjustment and efficient power drive can meet various cylinder drilling needs, improving machining accuracy and efficiency while reducing scrap rates.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model provides the following technical solution: Example 1

[0030] Please see Figure 1-4 This utility model provides a technical solution: a drilling device for cylinder processing, including a base 1, a support leg 2 fixedly connected to the bottom of the base 1, a fixed rod 3 fixedly connected to the top of the base 1, a lifting and rotating mechanism 4 provided at the bottom of the base 1, a fixed frame 5 fixedly connected to the top of the fixed rod 3, and a drilling mechanism 6 provided on the inner wall of the fixed frame 5.

[0031] The lifting and rotating mechanism 4 includes a lifting component 41 and a rotating component 42. The lifting component 41 is disposed at the bottom of the base 1, and the rotating component 42 is disposed at the top of the lifting component 41.

[0032] The rotating assembly 42 includes a second fixed frame 421, which is located on top of the lifting assembly 41. A fixed sleeve 422 is fixedly connected to the left side of the front of the second fixed frame 421. A second servo motor 423 is fixedly connected inside the fixed sleeve 422. A worm gear 424 is fixedly connected to the output end of the second servo motor 423. A first rotating shaft 425 is rotatably connected to the left side of the second fixed frame 421 near the top. A worm wheel 426 is fixedly connected to the surface of the first rotating shaft 425 near the left end. A first clamping plate 427 is fixedly connected to the right end of the first rotating shaft 425. A cylinder 428 is fixedly connected to the right side of the second fixed frame 421 near the bottom. A moving plate 429 is fixedly connected to the output end of the cylinder 428. A second guide rod 4211 is symmetrically fixed to the right side of the moving plate 429. A second rotating shaft 4212 is rotatably connected to the left side of the moving plate 429 near the top.

[0034] The second fixing bracket 421 has a hole on its right side that matches the first guide rod 419. The surface of the first guide rod 419 passes through and slides left and right in the hole. By sliding the first guide rod 419 left and right in the hole, the cylinder held by the first clamping plate 427 and the second clamping plate 4213 can be rotated more stably.

[0035] The lifting assembly 41 includes a first fixed frame 411, which is fixedly connected to the bottom of the base 1. Bidirectional lead screws 412 are rotatably connected to the left and right sides of the first fixed frame 411 near the bottom. A first servo motor 413 is fixedly connected to the right side of the first fixed frame 411 near the bottom. A first hinge frame 414 is symmetrically threaded to the surface of the bidirectional lead screw 412. Limit rods 415 are fixedly connected to the bottom of the left and right sides of the first fixed frame 411. A hinge rod 416 is hinged to the first hinge frame 414. A second hinge frame 417 is hinged to the other end of the hinge rod 416. A lifting seat 418 is fixedly connected to the top of the second hinge frame 417. A first guide rod 419 is symmetrically fixedly connected to the bottom of the lifting seat 418.

[0036] The output end of the first servo motor 413 is fixedly connected to the right end of the bidirectional lead screw 412.

The top of the lifting seat 418 is fixedly connected to the bottom of the second fixed frame 421. Example 2

[0038] Please see Figure 5-6 Furthermore, based on Embodiment 1, a punching mechanism 6 was obtained.

[0039] The drilling mechanism 6 includes a rectangular frame 61, which is fixedly connected to the inner wall of the fixed frame 5 on both sides. A sliding sleeve 62 is slidably connected to the surface of the rectangular frame 61. A movable frame 63 is fixedly connected to the surface of the sliding sleeve 62. A third rotating shaft 64 is rotatably connected to the front and rear sides of the movable frame 63. A gear 65 is fixedly connected to the middle of the surface of the third rotating shaft 64. A third servo motor 66 is fixedly connected to the front of the movable frame 63. A rack 67 is fixedly connected to the left and right sides of the inner wall of the rectangular frame 61. A fixed plate 68 is fixedly connected to the bottom of the movable frame 63. A fourth servo motor 69 is fixedly connected to the bottom of the fixed plate 68. A drill bit 611 is fixedly connected to the output end of the fourth servo motor 69.

[0040] Gear 65 meshes with rack 67, and the output end of the third servo motor 66 is fixedly connected to the front end of the third rotating shaft 64.

[0041] In actual operation, when this device is used, the cylinder is placed between the first clamping plate 427 and the second clamping plate 4213, and the cylinder 428 is activated. The output end of the cylinder 428 pushes the moving plate 429 to the left. The first guide rod 419 on the right side of the moving plate 429 slides in the hole opened on the right side of the second fixed frame 421, ensuring the stability of the movement of the moving plate 429. As the moving plate 429 moves, the second clamping plate 4213 gradually approaches the first clamping plate 427, thereby clamping and fixing the cylinder. When it is necessary to rotate the cylinder, the second servo motor 423 is activated. The worm gear 424 at the output end of the second servo motor 423 rotates. Since the worm gear 424 meshes with the worm wheel 426, it will drive the worm wheel 426 and the first rotating shaft 425 fixedly connected to it to rotate, thereby causing the first clamping plate 427 at the right end of the first rotating shaft 425 to rotate, driving the cylinder to rotate. During the rotation of the cylinder, the first guide rod 419 slides within the hole of the second fixed frame 421, further ensuring the stability of the cylinder rotation. The rectangular frame 61 of the drilling mechanism 6 is fixed to both sides of the inner wall of the fixed frame 5. When it is necessary to adjust the lateral position of the drill bit 611, the third servo motor 66 is activated. The output end of the third servo motor 66 drives the third rotating shaft 64 to rotate, and the gear 65 on the surface of the third rotating shaft 64 rotates accordingly. Since the gear 65 meshes with the racks 67 on the left and right sides of the inner wall of the rectangular frame 61, when the gear 65 rotates, it will drive the moving frame 63 and the sliding sleeve 62 fixedly connected to it to slide left and right along the surface of the rectangular frame 61, thereby achieving precise adjustment of the lateral position of the drill bit 611 to align with the position on the cylinder where drilling is required. After the drill bit 611 is adjusted to the appropriate lateral position, the fourth servo motor 69 is activated. The output end of the fourth servo motor 69 drives the drill bit 611 to rotate at high speed, activating the first servo motor 413. The output shaft of the first servo motor 413 drives the bidirectional lead screw 412 to rotate. Because the surface of the bidirectional lead screw 412 is symmetrically threaded with first hinge frames 414, and the hole near the bottom on the left side of the first hinge frame 414 is slidably connected to the limiting rod 415, under the limiting action of the limiting rod 415, as the bidirectional lead screw 412 rotates, the two first hinge frames 414 will move towards or away from each other along the limiting rod 415. The first hinge frame 414 is hinged to the second hinge frame 417 through the hinge rod 416. When the first hinge frame 414 moves, it will drive the hinge rod 416 to move, thereby pushing the second hinge frame 417 to move up and down. The lifting seat 418 at the top of the second hinge frame 417 also rises and falls accordingly. The four first guide rods 419 at the bottom of the lifting seat 418 slide up and down in the holes opened at the top of the base 1, which plays a role in stabilizing and supporting the lifting seat 418, making the lifting process more stable, and then drilling operations are performed on the cylinder.
