Description

Technical Field

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

[0002] Currently, during the production and maintenance of drying cylinders, drilling is typically required on their outer wall or ends to install positioning components or for further assembly. Existing drilling equipment mostly uses fixed drilling units with simple support bases to process the cylinder, and the positioning method is usually single-sided support or manual adjustment and clamping.

[0003] In typical structures, the cylinder is often supported by a flat plate or V-shaped bracket and then fixed by a pressure plate or bolts. While this type of structure can meet drilling requirements to some extent, the cylinder is often cylindrical with a smooth surface and thin walls. During drilling, uneven stress or insecure clamping can cause displacement, resulting in inaccurate drilling positions and affecting the coaxiality and machining accuracy of the holes. This displacement problem is particularly pronounced in multi-hole or precision installation applications.

[0004] In addition, existing devices also have shortcomings in clamping operations. On the one hand, traditional bolt tightening or mechanical jaw clamping requires manual adjustment one by one, resulting in low clamping efficiency and cumbersome operation; on the other hand, the diameter of drying cylinders of different specifications varies greatly, and existing devices often require special clamps, which have poor versatility and make it difficult to accommodate multiple cylinder specifications on a single set of equipment, increasing equipment costs and maintenance difficulty.

[0005] In summary, existing drilling equipment for drying cylinders generally suffers from problems such as unstable positioning, easy deviation, insufficient machining accuracy, complex clamping operations, and poor adaptability. There is an urgent need for an improved solution that can improve clamping efficiency and versatility while ensuring drilling accuracy. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: a drilling device for preventing deviation of the drying cylinder, comprising a drilling unit, a drill base, a fastener assembly, and a support groove seat, which can stably support and clamp the drying cylinder in multiple directions, ensuring the accuracy and stability of the drilling operation. This device uses a drive cylinder to drive the pull sleeve and the variable diameter sleeve to work together, combined with the support groove seat limiting the bottom of the cylinder, to achieve rapid clamping and anti-deviation positioning, thereby improving drilling efficiency and adaptability.

[0008] The overall structure of this utility model includes a drilling unit, a drill base, and a fastener assembly, with a detachable mounting base on the surface of the drill base. The drilling unit is fixedly mounted above the drill base for drilling the drying cylinder. The drill base serves both to support the drying cylinder and as the mounting base for the fastener assembly. This structure achieves an integrated layout of the drilling unit and the clamping system, effectively ensuring the stability of the cylinder during processing.

[0009] The fastener assembly includes a fixed sleeve, a guide sleeve, a reducing sleeve, and a pull sleeve. The fixed sleeve is fixedly mounted on the surface of the drill base, the guide sleeve is mounted inside the fixed sleeve, the reducing sleeve is movably sleeved on the end of the guide sleeve, and the pull sleeve mates with the reducing sleeve. A pull assembly is rotatably mounted on the drill base, the top of which is connected to the output end of a drive cylinder. The drive cylinder drives the pull assembly to move the pull sleeve axially along the guide sleeve, thereby achieving the clamping or releasing operation of the reducing sleeve. Specifically, this configuration automates and simplifies the cylinder clamping process.

[0010] In a preferred example, the front end of the guide tube is provided with a tapered groove, which has an inwardly tapered structure. This structure guides the end of the variable diameter sleeve to contract or expand under axial force. Specifically, it enables the cylinder to achieve stable radial clamping within different diameter ranges.

[0011] In a preferred example, the end of the reducing sleeve is provided with several conical lugs, and a groove is formed between adjacent conical lugs, extending along the axial direction of the reducing sleeve. This structure enables the conical lugs to have independent radial elastic deformation capabilities, specifically, it can form a uniform circumferential clamping effect, thereby improving the reliability of the cylinder's anti-deviation positioning.

[0012] In a preferred example, the pull sleeve is fitted around the outer periphery of the guide tube, with one end connected to the pull assembly via a hinged structure, and the other end abutting against the outer wall of the reducing sleeve. This structure ensures that the pull sleeve can move stably along the axial direction of the guide tube under the action of the pull assembly, specifically making the pushing and releasing process of the reducing sleeve smoother.

[0013] In a preferred embodiment, lugs are fixedly provided on both sides of the outer wall of the pull sleeve, and the pull sleeve is hinged to the lugs via pins. This structure ensures that the pull sleeve is subjected to uniform force during reciprocating linear motion, specifically improving the stability and reliability of the driving process.

[0014] In a preferred example, the support seat has a V-shaped groove structure and is detachably connected to the drill bit by bolts. This structure not only provides reliable bottom support for the drying cylinder but also allows for the replacement of different specifications of support seats according to the cylinder diameter, thereby improving the adaptability and versatility of the device.

[0015] In a preferred example, the drive cylinder is a pneumatic or hydraulic cylinder, with its output end fixedly connected to the top of the pull assembly. This structure provides a stable linear drive force, specifically ensuring accurate and reliable clamping and releasing operations of the fastener assembly.

[0016] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting a grooved seat and a fastener assembly on the drill bit, dual positioning and clamping of the drying cylinder body are achieved. The V-shaped groove of the grooved seat can stably support the cylinder body, and the guide tube, reducing sleeve and pull sleeve in the fastener assembly, together with the conical groove, conical lug and crack groove, form a radial limiting clamping structure, which effectively prevents the cylinder body from shifting during drilling, thereby improving the accuracy and coaxiality of the drilling position.

[0017] 2. In this utility model, the fastener assembly adopts a flexible shrinkable variable diameter sleeve structure, and realizes automatic clamping and release operations through the drive cylinder and the pull assembly, making the clamping process convenient and fast; at the same time, the support seat is detachable and replaceable, which can be adapted to different specifications of drying cylinders, improving the versatility and adaptability of the device, and further improving processing efficiency.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a drying cylinder anti-deviation drilling device.

[0023] Combination Figures 1-4 As shown, the present invention provides a drying cylinder anti-deviation drilling device, which includes a drilling unit 100, a drill base 200, a fastener group 300, and a support groove seat 210.

[0024] The drilling unit 100 is fixedly installed above the drill base 200 and is used to drill holes in the drying cylinder. The drill base 200 is used to support the drying cylinder and install the fastener assembly 300. The support groove 210 is detachably installed on the surface of the drill base 200 and is used to support and limit the outer circle of the drying cylinder.

[0025] The fastener assembly 300 includes a fixed sleeve 310, a guide cylinder 320, a reducing sleeve 330, and a pull sleeve 340. The fixed sleeve 310 is fixedly mounted on the surface of the drill base 200. The guide cylinder 320 is mounted inside the fixed sleeve 310. The reducing sleeve 330 is movably sleeved on the end of the guide cylinder 320. The pull sleeve 340 cooperates with the reducing sleeve 330. A pull assembly 410 is rotatably mounted on the drill base 200. The top end of the pull assembly 410 is connected to the output end of a drive cylinder 400. The drive cylinder 400 can drive the pull assembly 410 to move the pull sleeve 340 axially along the guide cylinder 320, thereby achieving the clamping or releasing operation of the reducing sleeve 330.

[0026] In this embodiment, the front end of the guide cylinder 320 is provided with a conical groove 321, which has an inwardly tapered structure. This structure allows the end of the variable diameter sleeve 330 to contract and expand under the guidance of the inner wall of the conical groove 321, so as to adapt to the radial clamping of the cylinder.

[0027] In this embodiment, the end of the variable diameter sleeve 330 is provided with a plurality of conical lugs 331, and a groove 332 is formed between adjacent conical lugs 331. The groove 332 extends along the axial direction of the variable diameter sleeve 330, thereby enabling the conical lugs 331 to undergo independent radial elastic deformation. This structure allows the variable diameter sleeve 330 to form a uniform circumferential clamping effect under the guidance of the conical groove 321 of the guide cylinder 320 through the multiple conical lugs 331.

[0028] In this embodiment, the pull sleeve 340 is sleeved on the outer periphery of the guide cylinder 320. One end of the pull sleeve 340 is connected to the pull assembly 410 via a hinge structure, and the other end abuts against the outer wall of the variable diameter sleeve 330. Through this structure, the pull sleeve 340 moves along the direction of the guide cylinder 320 under the drive of the pull assembly 410, thereby pushing or releasing the variable diameter sleeve 330.

[0029] In this embodiment, lugs 341 are fixedly provided on both sides of the outer wall of the pull sleeve 340, and the pull assembly 410 is hinged to the lugs 341 via a pin. Through this hinged structure, when the drive cylinder 400 drives the pull assembly 410 to move, the pull sleeve 340 can maintain a stable reciprocating linear motion and avoid deviation.

[0030] In this embodiment, the support seat 210 has a V-shaped groove structure and is detachably connected to the drill base 200 by bolts. This structure provides stable bottom support for the drying cylinder and allows for the replacement of different sized support seats 210 according to different cylinder diameters, thus improving the adaptability of the device.

[0031] In this embodiment, the drive cylinder 400 is a pneumatic cylinder or a hydraulic cylinder, and the output end of the drive cylinder 400 is fixedly connected to the top end of the pull assembly 410. This structure enables the drive cylinder 400 to provide a stable linear driving force, ensuring reliable clamping and releasing operations of the fastener assembly 300.

[0032] In summary, this utility model, through the cooperation of the drilling unit 100, drill base 200, support seat 210, fastener assembly 300, drive cylinder 400, and pull assembly 410, achieves stable support and radial clamping of the drying cylinder body, effectively preventing cylinder body displacement during drilling and ensuring drilling accuracy. Simultaneously, the support seat 210 is detachable and replaceable, and the reducing sleeve 330 achieves elastic clamping through the structure of the slot 332 and the conical lug 331. Combined with the power control of the drive cylinder 400, rapid clamping and release are achieved, improving the applicability and operational efficiency of the device.

[0033] Working principle and usage process of this utility model: During use, the drying cylinder is first placed on the surface of the drill base 200, and the lower part of the cylinder is embedded in the V-shaped groove structure of the support seat 210, thus achieving initial positioning. The support seat 210 is detachably installed on the drill base 200 by bolts, and can be replaced during the processing of drying cylinders of different specifications to ensure compatibility and stability.

[0034] Subsequently, the cylinder is radially clamped using the fastener assembly 300. The fastener assembly 300 includes a fixed sleeve 310, a guide cylinder 320, a reducing sleeve 330, and a pull sleeve 340. The guide cylinder 320 is installed inside the fixed sleeve 310, and its front end has a tapered groove 321 to form an inwardly tapered support interface. The reducing sleeve 330 is movably fitted onto the end of the guide cylinder 320. The end of the reducing sleeve 330 has several tapered lugs 331, and axially extending slots 332 are formed between adjacent tapered lugs 331, allowing the reducing sleeve 330 to have a certain elastic expansion and contraction space. The pull sleeve 340 is fitted onto the outer periphery of the guide cylinder 320, with its front end abutting against the outer wall of the reducing sleeve 330, and its rear end hinged to the pull assembly 410 via a lug 341.

[0035] During the clamping operation, the drive cylinder 400 outputs a linear thrust, which drives the pull sleeve 340 to move axially along the guide cylinder 320 via the pull assembly 410, causing the pull sleeve 340 to press the variable diameter sleeve 330 towards the conical groove 321. With the pulling force, the conical lug 331 of the variable diameter sleeve 330 radially contracts under the cooperation of the conical groove 321, clamping the outer wall of the drying cylinder body and achieving stable fixation.

[0036] During the release operation, the drive cylinder 400 drives the pull assembly 410 to move in the opposite direction, and the pull sleeve 340 moves backward, releasing the clamping effect on the variable diameter sleeve 330. The cone lug 331 returns to its original state by relying on its own elasticity and the deformation space of the groove 332, thereby loosening the drying cylinder body, making it easier to remove or replace the workpiece.

[0037] After positioning and clamping, the drilling unit 100 performs drilling above the drill base 200. The V-shaped groove of the support seat 210 provides stable support for the cylinder, and the fastener assembly 300 provides radial positioning and clamping of the cylinder. Together, these features effectively prevent cylinder misalignment during drilling, ensuring accurate drilling position and coaxiality. Therefore, this invention enables rapid clamping, stable positioning, and anti-deviation drilling of the drying cylinder, guaranteeing processing accuracy and improving production efficiency.
