Description

Technical Field

[0001] The present invention relates to the technical field of milling machines, and particularly to a giant tank surface milling machine. Background Art

[0002] A milling machine is a machine tool with a wide range of uses. On a milling machine, planes (horizontal planes, vertical planes), grooves (keyways, T-slots, dovetail grooves, etc.), tooth-dividing parts (gears, spline shafts, sprockets), helical surfaces (threads, helical grooves) and various curved surfaces can be machined. In addition, it can also be used for machining the surface of a rotating body, internal holes and cutting work, etc. However, traditional milling machines are all for milling ordinary-sized products. During milling, the workpiece is clamped by a fixture on the workbench. However, power plants and shipyards often need to use large-scale tank container equipment, whose diameter can reach several meters and height can reach several meters or even more than ten meters. Such tank containers usually need to withstand strong pressure inside, so the overall of such tank containers is usually made of metal, including the annular tank body of the main part. The upper and lower parts of the tank body are fixedly connected with upper and lower sealed ends by welding or other means.

[0013] The present invention provides a giant tank surface milling machine. It has the following beneficial effects: 1. For this giant tank surface milling machine, by setting the adhesion mechanism, the giant waste cut during milling is transferred. When the existing milling machine mills a giant tank, since the waste size is large, the waste is likely to hurt workers or hit the items around the equipment when it falls. Therefore, the adhesion mechanism is set, and the contact component is controlled by the motor to deflect, thereby controlling the deflection of the waste cut during milling, so that the waste is away from the giant tank and falls steadily at a position away from the tool rest component, which is convenient for the staff to manually disassemble the waste and recycle the waste, and avoid the situation that the giant waste accumulates on the workbench after milling work or hurts workers or hits the items around the equipment when it falls.

[0014] 2. For this giant tank surface milling machine, by setting the contact component, the waste is adhered or pushed. During the milling work, the clamping plate and the rubber strip are at the top of the giant tank to limit the giant tank, and the side plate and the adhesive strip are at one end of the giant tank that needs to be milled to limit the milling position of the giant tank, which is convenient for the waste to adhere to the outside of the adhesive strip. After the milling work, by adjusting the angles of the clamping plate and the side plate, the angle of the waste is adjusted, which is convenient for the transfer and pushing work of the waste.

[0015] 3. The giant tank body surface milling machine controls the positions of the moving box and the giant tank body on top of the moving box through the setting of a moving mechanism under the operation of the first push rod. By setting a connecting pipe, the excessive lubricating fluid in the moving box is discharged through the connecting pipe, reducing the lubricating fluid accumulated at the milling position.

[0016] 4. The giant tank body surface milling machine fixes the end of the giant tank body far from the tool rest assembly through the setting of a limiting mechanism. By symmetrically setting multiple groups of deformable rubber plates, the giant tank body is limited. When the rubber plates are in the initial state, the giant tank body can be contacted and fixed, and when milling a batch of giant tank bodies, only the position of the slider needs to be adjusted after the first giant tank body is loaded, and the positions of the diagonal plate and the rubber plates are adjusted. When the rubber plates are in the squeezed state, the rubber plates are in the direction away from the giant tank body, and the work of releasing the giant tank body can be completed.

Detailed implementation mode

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0020] As Figures 1-9 shown, the present invention provides a technical solution: including a milling machine 1, a tool rest assembly 2 is installed inside the milling machine 1, and the tool rest assembly 2 is controlled by a hydraulic system to mill a giant tank body; A chute 8 is opened inside the milling machine 1; A chamber 7 is opened inside the milling machine 1, and a first push rod 6 is installed inside the chamber 7; A moving mechanism 3 is connected to the outside of the first push rod 6. The moving mechanism 3 includes a moving box 302. A connecting block 301 is installed at the bottom of the moving box 302. The connecting block 301 is slidably connected inside the chute 8. The connecting block 301 is connected to the first push rod 6. The first push rod 6 is used to drive the connecting block 301 and the moving box 302 to move; A limiting mechanism 4 is arranged outside the moving mechanism 3. The limiting mechanism 4 includes a rubber plate 404 and a third push rod 408. The third push rod 408 is used to control the deformation of the rubber plate 404; An adhesion mechanism 5 is arranged outside the moving mechanism 3. The adhesion mechanism 5 includes a contact assembly 506. The moving mechanism 3 is used to drive the contact assembly 506 to deflect.

[0021] Before using the device, adjust the limit mechanism 4 and the adhesion mechanism 5, and use an external transfer table to transport the giant tank body onto the moving box 302. Subsequently, adjust the stroke of the first push rod 6. The first push rod 6 drives the connection block 301 and the moving box 302 to move. At this time, the position of the giant tank body that needs to be milled starts to move towards the tool rest assembly 2. Turn on the tool rest assembly 2 to perform the milling work on the giant tank body. After this milling work is completed, adjust the adhesion mechanism 5 to transfer the large waste cut off by milling. After all the milling work is completed, adjust the first push rod 6 to its initial state, adjust the limit mechanism 4 to release the tank body, and use an external transfer table to transport the giant tank body out from the loading direction.

[0022] The moving mechanism 3 further includes: A fixed frame 303, which is installed outside the moving box 302. A slider 304 is slidably connected inside the fixed frame 303. There are two sliders 304, and a power system is arranged inside each of the two sliders 304. The slider 304 is connected to the limit mechanism 4; Motor boxes 305, which are installed outside the moving box 302. There are two motor boxes 305, and they are symmetrically arranged. Motors are arranged inside each of the two motor boxes 305. The adhesion mechanism 5 is connected to the output end of the motor; Connecting pipes 306, which are installed at the bottom of the moving box 302. There are two connecting pipes 306; A first groove 307, which is opened inside the moving box 302. A circulation hole 308 is opened inside the first groove 307. There are several circulation holes 308; A central plate 309, which is arranged inside the moving box 302, and the edge of the central plate 309 is recessed towards the direction of the first groove 307 to facilitate the lubricating fluid to flow towards the first groove 307.

[0023] By turning on the power system in the slider 304, control the position of the slider 304 in the fixed frame 303, and then adjust the position of the limit mechanism 4 connected to the slider 304.

[0024] By turning on the motor, control the deflection work of the adhesion mechanism 5 by the motor.

[0025] By providing the connecting pipes 306, as the lubricating fluid in the moving box 302 increases, most of the lubricating fluid flows through the central plate 309 to the first groove 307, and enters the inside of the moving box 302 through the circulation holes 308 in the first groove 307, and then flows downward through the connecting pipes 306 at the bottom of the moving box 302.

[0026] By setting up the moving mechanism 3, under the action of the first push rod 6, the positions of the moving box 302 and the giant tank on top of the moving box 302 are controlled. By setting up the connecting pipe 306, the excessive lubricating fluid in the moving box 302 is discharged through the connecting pipe 306, reducing the lubricating fluid accumulated at the milling position.

[0027] The limiting mechanism 4 further includes: A second push rod 401, which is installed outside the slider 304, and a first adjusting rod 402 is installed outside the second push rod 401; Angle plates 403, which are installed outside the first adjusting rod 402, there are multiple angle plates 403, the angle plates 403 are set as L-shaped plates, and a rubber plate 404 is installed outside the angle plates 403; Second adjusting rods 405, which are installed outside the angle plates 403 and penetrate through the angle plates 403, there are multiple second adjusting rods 405, and the multiple second adjusting rods 405 are used to connect the multiple angle plates 403; Third adjusting rods 406, which are installed inside the rubber plate 404 and penetrate through the rubber plate 404, there are multiple third adjusting rods 406, and the multiple third adjusting rods 406 are used to connect the multiple rubber plates 404; An extension plate 407, which is installed outside the angle plate 403, and the extension plate 407 is connected to the fixed end of the third push rod 408; A joint 409, which is connected to the telescopic end of the third push rod 408, and the joint 409 is connected to the third adjusting rod 406.

[0028] Before using the equipment, the third push rod 408 is in the open state, and at this time the rubber plate 404 is in the natural state. As the giant tank moves to the top of the moving box 302, the power system in the slider 304 is turned on, and the slider 304 starts to move in the fixed frame 303 until the angle plates 403 on both sides are in the position close to the giant tank, and the rubber plates 404 among the multiple angle plates 403 start to contact and fix the giant tank.

[0029] When it is necessary to release the giant tank, the third push rod 408 is adjusted to the initial stroke, and the third push rod 408 starts to drive the joint 409 and the third adjusting rod 406 to move towards the direction close to the angle plate 403. The third adjusting rod 406 starts to squeeze the rubber plate 404, and the rubber plate 404 deforms and gradually separates from the giant tank.

[0030] As the next giant tank moves to the top of the moving box 302, only the stroke of the third push rod 408 needs to be adjusted, and there is no need to adjust the position of the slider 304 again.

[0031] By setting the limit mechanism 4, the end of the giant tank body far from the tool rest assembly 2 is contact-fixed. By symmetrically arranging multiple groups of deformable rubber plates 404, the giant tank body is limited. When the rubber plate 404 is in the initial state, it can contact and fix the giant tank body. And when milling a batch of giant tank bodies, only the position of the slider 304 needs to be adjusted after the first giant tank body is loaded, and the positions of the diagonal plate 403 and the rubber plate 404 are adjusted. When the rubber plate 404 is in the squeezed state, the rubber plate 404 is in the direction away from the giant tank body, and the work of releasing the giant tank body can be completed.

[0032] The adhesion mechanism 5 further includes: A connecting column 501, the connecting column 501 is connected to the output end of the motor, and a fourth push rod 502 is installed outside the connecting column 501; A connecting platform 503, the connecting platform 503 is installed outside the fourth push rod 502, and a fifth push rod 504 is installed outside the connecting platform 503; A side plate 505, the side plate 505 is installed outside the fifth push rod 504, and a contact assembly 506 is arranged outside the side plate 505; A sixth push rod 507, the sixth push rod 507 is installed outside the side plate 505, and a vertical rod 508 is installed outside the sixth push rod 507; A support rod 509, the support rod 509 is installed outside the vertical rod 508, and there are two support rods 509.

[0033] According to the height of the giant tank body, the stroke of the fourth push rod 502 is adjusted so that the contact assembly 506 can contact the top of the giant tank body. As the giant tank body moves onto the moving box 302, the end of the giant tank body that needs to be milled gradually contacts the side plate 505, and then the tool rest assembly 2 starts the milling work. One end of the milled waste still contacts the side plate 505.

[0034] The fourth push rod 502 is turned on, the fourth push rod 502 drives the connecting platform 503, the fifth push rod 504, the side plate 505 and the contact assembly 506 to move upward. Then the motor is turned on, and the motor drives the fourth push rod 502, the connecting platform 503, the fifth push rod 504, the side plate 505 and the contact assembly 506 to deflect, thereby driving the waste in the contact assembly 506 to deflect. Then the worker manually disassembles the waste.

[0035] By setting the adhesion mechanism 5, the transferred giant waste is transferred. The motor controls the deflection of the contact assembly 506, thereby controlling the deflection of the milled waste, so that the waste is away from the giant tank body and stably falls at a position away from the tool rest assembly 2, which is convenient for the staff to manually disassemble the waste and recycle the waste, and avoids the situation that the giant waste accumulates on the workbench after the milling work or hurts the workers or impacts the items around the equipment when falling.

[0036] The contact component 506 includes: A clamping plate 5061, which is installed on the top of the side plate 505 and is set in an arc shape; A rubber strip 5062, which is installed at the bottom of the clamping plate 5061. There are multiple rubber strips 5062 and they are evenly arranged; An adhesion strip 5063, which is installed outside the side plate 505. There are multiple adhesion strips 5063 and they are evenly arranged; A channel 5064, which is opened inside the side plate 505. There are two channels 5064; A push plate 5065, which is installed outside the support rod 509. There are two push rods.

[0037] Before using the device, the sixth push rod 507 is in the open state. At this time, the push plate 5065 is in a position away from the channel 5064.

[0038] As the giant tank approaches the contact component 506, the rubber strip 5062 contacts the top of the giant tank, and the adhesion strip 5063 adheres to one end of the giant tank that needs to be milled.

[0039] After the deflection of the contact component 506 ends, adjust the sixth push rod 507 to the initial stroke. The sixth push rod 507 drives the vertical rod 508, the support rod 509 and the push plate 5065 to move. The push plate 5065 gradually contacts the waste through the channel 5064, separating the waste from the adhesion strip 5063 to assist the worker in taking the waste.

[0040] By setting the contact component 506, adhesion or pushing work is carried out on the waste. During the milling work, the clamping plate 5061 and the rubber strip 5062 are at the top of the giant tank to limit the giant tank. The side plate 505 and the adhesion strip 5063 are at one end of the giant tank that needs to be milled to limit the milling position of the giant tank, facilitating the adhesion of the waste outside the adhesion strip 5063. After the milling work, by adjusting the angles of the clamping plate 5061 and the side plate 505, the angle of the waste is adjusted to facilitate the transfer and pushing work of the waste. [[ID=2,4,6,8,10,12,15,18,21,24,27]]

[0041] Working principle: Before using the device, according to the height of the giant tank, adjust the stroke of the fourth push rod 502 so that the contact component 506 can contact the top of the giant tank.

[0042] Use an external conveyor table to transport the giant tank to the moving box 302. As the giant tank moves onto the moving box 302, one end of the giant tank that needs to be milled gradually contacts the side plate 505. As the giant tank approaches the contact component 506, the rubber strip 5062 contacts the top of the giant tank, and the adhesion strip 5063 adheres to one end of the giant tank that needs to be milled.

[0043] As the giant tank body moves to the top of the moving box 302, the power system in the slider 304 is turned on, and the slider 304 starts to move in the fixed frame 303 until the corner plates 403 on both sides are in a position close to the giant tank body, and the multiple rubber plates 404 in the multiple corner plates 403 start to contact and fix the giant tank body.

[0044] Adjust the stroke of the first push rod 6. The first push rod 6 drives the connecting block 301 and the moving box 302 to move. At this time, the position of the giant tank body that needs to be milled starts to move towards the tool rest assembly 2. Subsequently, the tool rest assembly 2 starts the milling work, and one end of the milled waste still contacts the side plate 505.

[0045] After the milling work is completed this time, adjust the adhesion mechanism 5 to transfer the large waste milled off.

[0046] Turn on the fourth push rod 502. The fourth push rod 502 drives the connecting platform 503, the fifth push rod 504, the side plate 505, and the contact assembly 506 to move upward. Subsequently, turn on the motor, and the motor drives the fourth push rod 502, the connecting platform 503, the fifth push rod 504, the side plate 505, and the contact assembly 506 to deflect. As the deflection of the contact assembly 506 ends, adjust the sixth push rod 507 to its initial stroke. The sixth push rod 507 drives the vertical rod 508, the support rod 509, and the push plate 5065 to move. The push plate 5065 gradually contacts the waste through the channel 5064, separating the waste from the adhesion strip 5063 to assist the worker in taking the waste.

[0047] After all the milling work is completed, adjust the first push rod 6 to its initial state, and adjust the limiting mechanism 4 to release the tank body. When the giant tank body needs to be released, adjust the third push rod 408 to its initial stroke. The third push rod 408 starts to drive the joint 409 and the third adjusting rod 406 to move towards the corner plate 403. The third adjusting rod 406 starts to squeeze the rubber plate 404, and the rubber plate 404 deforms and gradually separates from the giant tank body. Subsequently, use an external transfer table to transport the giant tank body out in the loading direction.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
