Description

Technical Field

[0001] The utility model belongs to the technical field of profile cutting, and in particular relates to a clamping and positioning device for cutting tailings. Background Art

[0002] When an existing laser cutting machine cuts a profile, the laser cutting head cuts the profile under the control of a program, and the cut profile falls freely on the frame. When the cut profile hits the frame or the bottom surface when it falls, it is very easy to deform and damage; and when cutting the tail material, since it is necessary to cut the tail material of the profile, the profile tail material cannot be cut due to the interference between the clamped part and the cutting head; therefore, there is an urgent need to clamp and support the tail material at the rear end of the laser cutting position to achieve the cutting of the tail material.

[0003] Most of the existing blanking devices have solved the problem that the profile cannot be controlled to fall freely under the action of gravity after cutting; for example, a profile cutting machine with patent publication number CN104476371B discloses "including a feeding mechanism, a profile cutting chamber and a positioning mechanism, the feeding mechanism includes a pushing track, a pushing trolley and a feeding control system, the profile cutting chamber includes a feeding port, a discharging port and a cutting system, the cutting system includes a cutting machine, a clamping tool and a station detection device, a chip processing mechanism consisting of a guide fan and a chip removal channel is provided at the lower rear part of the profile cutting chamber, the chip removal channel is connected to the interior of the profile cutting chamber through the guide fan, and the guide fan forms a negative pressure in the profile cutting chamber to remove the cutting products. The raw chips are discharged from the chip discharge channel. The positioning mechanism includes a positioning ruler, a limit block and a limit block bracket. The limit block slides along the limit block bracket to block the profile. The positioning ruler is set at the edge of the limit block bracket to determine the cutting length of the profile. The present invention can effectively collect metal debris generated during the cutting process, solve the safety problems existing in the current profile cutting machine, and improve the cutting accuracy of the profile. "Although the above structure can realize the cutting of the profile, the above device cannot realize the clamping and cutting of the rear end of the profile tail when the profile tail is short, resulting in a large amount of waste of tail; therefore, there is an urgent need for a device that can be set at the rear end of the cutting machine to assist in the cutting of the tail, so as to realize the cutting of the tail.

[0004] In order to solve the above problems, we provide a clamping and positioning device for cutting tailings that can cut the tailings of the profile and can move relative to the left and right positions. Utility Model Content

[0005] The utility model aims to overcome the deficiencies in the prior art and provide a clamping and positioning device for cutting tailings.

[0006] The purpose of the utility model is achieved as follows: a clamping and positioning device for cutting tail materials, comprising a base, a placing frame is provided on the base, a vertical frame is fixedly provided on the placing frame, a pressure plate is provided on the vertical frame and can be moved up and down, a bracket is provided on the vertical frame below the pressure plate and can be moved up and down, the upper part of the bracket is a V-shaped structure, and support rollers are rotatably provided on the left and right sides of the V-shaped structure of the upper part of the bracket.

[0007] Furthermore, a lifting cylinder is fixedly provided on the placement rack, and an output end of the lifting cylinder is connected to the bottom of the bracket, and the lifting cylinder drives the bracket to move up and down along the vertical frame.

[0008] Furthermore, a pressing plate cylinder is fixedly provided on the vertical frame, and an output end of the pressing plate cylinder is connected to the pressing plate, and the pressing plate cylinder drives the pressing plate to move up and down along the vertical frame.

[0009] Furthermore, a pressure plate roller is provided on the lower front surface of the pressure plate.

[0010] Furthermore, the support rollers on the left and right sides of the upper V-shaped structure of the bracket are both double-row support rollers.

[0011] The working principle of the utility model when in use: when the profile enters the device from the left side, the profile is located on the bracket. The height of the bracket can be adjusted by controlling the lifting cylinder to adapt to profiles of different sizes. The lifting and lowering of the bracket can realize the giving way function of the profile to move to the right, which is convenient for the profile to move to the right. When the tail material is above the bracket, the profile can be supported by the rising of the bracket to avoid the right end of the profile entering the tail material support blanking mechanism. The distance between the right end of the profile and the tail material support blanking mechanism is too long, causing the profile to bend and fall, causing the left end of the fixed plate on the tail material support blanking mechanism to bump, or the profile cannot be moved above the fixed plate; at the same time, multi-point support of the profile can better prevent the bending and deformation of the profile and reduce cutting errors. The support roller on the bracket can support the left side of the profile. At the same time, the support roller is provided to facilitate the movement of the profile, avoid wear of the profile caused by hard friction between the profile and the bracket, and reduce noise. The pressure plate cylinder is controlled to move downward, and then the pressure plate roller on the pressure plate cooperates with the support roller to clamp the profile. Since the bracket is a V-shaped structure, the clamping and positioning of the profile in the up, down, left and right directions can be achieved by cooperating with the pressure plate above.

[0012] Cylinder 1 is then controlled to move the pressure rod toward the support frame, compressing and clamping the profile on the right support frame. A rubber pad is installed on the lower surface of the pressure rod, which cooperates with the upper surface of the support frame to clamp the profile while preventing it from moving left or right. The right portion of the profile is located on a fixed plate, which supports the profile on the right side. The pressure plate and bracket cooperate with the pressure rod and support frame to clamp and position the profile, which can increase the stability of the profile during cutting. The rotating plate folds upward and cooperates with the fixed plate to prevent the profile from directly falling off the device and onto the ground after the clamping and positioning function is released. The rotation of the rotating plate is driven by the extension and contraction of cylinder 2.

[0013] The rollers on the fixed plate and the rotating plate can prevent the profile from being worn when it moves left and right, and the contact movement between the rollers and the profile can reduce noise; when the profile is cut (the cutting position can be selected as needed to cut on the left side of the pressure plate, or to cut between the pressure plate and the pressure rod); if the cutting position is between the pressure plate and the pressure rod, after the cutting is completed, the pressure rod is driven upward by controlling the first cylinder to release the clamping effect on the profile, and then the rotating plate is driven downward by controlling the second cylinder. The profile falls along the rotating plate under its own gravity, thereby realizing the blanking function of the tail material. At the same time, a movable frame that can move left and right is provided to cooperate with the pressure rod and the support frame to clamp the profile, so that the profile can be controlled to move left and right as needed. Since the profile can move left and right between the pressure plate and the support plate (the action of the pressure plate roller and the support roller can realize the left and right movement of the profile).

[0014] When the cutting position is on the left side of the pressure plate, after the cutting is completed, the pressure rod is driven to move upward by controlling the cylinder 1 to release the clamping effect on the profile, and the pressure plate cylinder is driven to move upward by controlling the pressure plate to release the clamping effect on the profile; then the cut profile is pushed to the right (the pushing method is not limited and is the existing technology). When the profile is separated from the bracket, the rotating plate is driven downward by controlling the cylinder 2, and the profile falls along the rotating plate under the action of its own gravity, thereby realizing the blanking function of the tail material.

[0015] The cylinder components in this application can be replaced by other structures with lifting functions, as long as they can achieve precise lifting control functions, without any technical restrictions. The movable frame can be moved left and right. When the cutting machine needs to be repaired and inspected, the movable frame can be moved to the right to provide sufficient maintenance space, making it easier for staff to operate. At the same time, a rotating plate with an adjustable rotation angle is provided, and the profile can be dropped along the rotating plate to avoid falling directly vertically to the ground and causing serious damage.

[0016] Beneficial effects: The present application can realize the supporting, clamping and limiting effect on the profile tailings when cutting the profile tailings, so as to facilitate the cutting of the tailings. At the same time, the double support roller structure is provided to increase the supporting effect on the profile, avoiding the point position support limitation caused by the single support roller and the pressure plate, resulting in poor profile support effect and affecting the profile cutting of the tailings.

[0028] A lifting cylinder 3 is fixed to the placement frame 2. The output end of the lifting cylinder 3 is connected to the bottom of the bracket 9, and the lifting cylinder 3 drives the bracket 9 up and down along the vertical frame 5. A pressure plate 6 cylinder 4 is fixed to the vertical frame 5. The output end of the pressure plate 6 cylinder 4 is connected to the pressure plate 6, and the pressure plate 6 cylinder 4 drives the pressure plate 6 up and down along the vertical frame 5. The pressure plate 6 is provided with a pressure plate roller 7105 on the lower front surface. The support rollers 8 on the left and right sides of the V-shaped structure above the bracket 9 are both double-row support rollers 8.

[0029] A movable frame 12 is mounted on the base 1, which can be moved left and right. A clamping mechanism is mounted on the movable clamp. This clamping mechanism includes a connecting plate 13, which is fixed to the left side of the movable frame 12. A pressure rod 15 is mounted on the connecting plate 13, which can be moved. A support frame 16 is fixed to the movable frame 12 below the pressure rod 15, and the pressure rod 15 is positioned above the support frame 16. A cylinder 14 is mounted on the connecting plate 13. The output end of the cylinder 14 is connected to the pressure rod 15, which drives the pressure rod 15 to move. The lower surface of the pressure rod 15 is parallel to the upper surface of the support frame 16, and the pressure rod 15 moves up and down perpendicular to the upper surface of the support frame 16.

[0030] The mobile frame 12 is also equipped with a tailing support and blanking mechanism 10. This mechanism includes a fixed plate 102, which is fixed to the mobile frame 12. A rotating plate 101 is rotatably mounted on the front of the mobile frame 12. The fixed plate 102 is tilted forward on the mobile frame 12 to facilitate the subsequent drop of the profile 11. The upper surface of the support frame 16 is coplanar with the upper surface of the fixed plate 102, facilitating support of the profile 11 during left and right movement. The support frame 16 is located to the right of the fixed plate 102.

[0031] A second cylinder 104 is provided on the movable frame 12 , and a driving rod 106 is provided on the lower surface of the rotating plate 101 . The output end of the second cylinder 104 is rotatably connected to the driving rod 106 , and the second cylinder 104 drives the rotating plate 101 to rotate through the driving rod 106 .

[0032] A motor 103 is fixedly installed on the base 1, and a rotating rod 107 is connected to the output end of the motor 103. The rotating rod 107 is rotatably connected to the base 1; the movable frame 12 is threadedly connected to the rotating rod 107, and the motor 103 drives the movable frame 12 to move left and right along the base 1 through the rotating rod 107. A plurality of rollers 105 are distributed on the fixed plate 102 and the rotating plate 101. The fixed plate 102 includes a bottom plate and a placement plate. A plurality of placement plates are provided on the bottom plate, and the placement plates are detachably located on the upper surface of the bottom plate. Since the fixed plate 102 mainly supports the profile 11, the placement plates are easily worn after long-term use. A detachable placement plate is provided to facilitate the replacement of the worn placement plates. Compared with a whole placement plate, a plurality of detachable placement plates are conducive to cost saving.

[0033] The working principle of the utility model when in use: when the profile 11 enters the device from the left side, the profile 11 is located on the bracket 9, and the height of the bracket 9 can be adjusted by controlling the lifting cylinder 3 to adapt to profiles 11 of different sizes; the support roller 8 on the bracket 9 can support the left side of the profile 11, and the support roller 8 is provided to facilitate the movement of the profile 11, avoiding the hard friction between the profile 11 and the bracket 9 causing wear of the profile 11, and reducing the generation of noise; by controlling the cylinder 4 of the pressure plate 6, the pressure plate 6 is driven to move downward, and then the pressure plate roller 7105 on the pressure plate 6 cooperates with the support roller 8 to clamp the profile 11. Since the bracket 9 is a V-shaped structure, the clamping and positioning of the profile 11 in the up, down, left and right directions can be achieved by cooperating with the pressure plate 6 above.

[0034] Then, the pressure rod 15 is driven to move toward the support frame 16 by controlling the first cylinder 14, thereby pressing and clamping the profile 11 located on the right support frame 16. A rubber pad is provided on the lower surface of the pressure rod 15, which cooperates with the upper surface of the support frame 16 to prevent the profile 11 from moving left and right while clamping the profile 11. The right part of the profile 11 is located on the fixed plate 102, which can support the profile 11 on the right side. The pressure plate 6 and the bracket 9 cooperate with the pressure rod 15 and the support frame 16 to clamp and position the profile 11, which can increase the stability of the profile 11 during cutting. The rotating plate 101 is folded upward and cooperates with the fixed plate 102 to prevent the profile 11 from directly detaching from the device and falling to the ground after the clamping and positioning function is released. The rotating plate 101 rotates and is driven to rotate by the extension and contraction of the second cylinder 104.

[0035] The rollers 105 on the fixed plate 102 and the rotating plate 101 can prevent the profile 11 from being worn when it moves left and right, and at the same time, the contact movement between the rollers 105 and the profile 11 can reduce noise; when the profile 11 is cut (the cutting position can be selected as needed to cut on the left side of the pressure plate 6, or to cut at a position between the pressure plate 6 and the pressure rod 15); if the cutting position is between the pressure plate 6 and the pressure rod 15, after the cutting is completed, the pressure rod 15 is driven to move upward by controlling the cylinder 14 to release the clamping effect on the profile 11, and then the rotating plate 101 is driven to rotate downward by controlling the cylinder 2 104, and the profile 11 falls along the rotating plate 101 under the action of its own gravity, thereby realizing the blanking function of the tail material.

[0036] At the same time, a movable frame 12 that can move left and right is provided to cooperate with the pressure rod 15 and the support frame 16 to clamp the profile 11, and the left and right movement of the profile 11 can be controlled as needed. The profile 11 can move left and right between the pressure plate 6 and the support plate (the rolling effect of the pressure plate roller 7105 and the support roller 8 can realize the left and right movement of the profile 11 relative to the pressure plate and the bracket) to facilitate the adjustment of the cutting position of the tail material.

[0037] When the cutting position is on the left side of the pressure plate 6, after the cutting is completed, the pressure rod 15 is driven to move upward by controlling the cylinder 14 to release the clamping effect on the profile 11, and the pressure plate 6 is driven to move upward by controlling the cylinder 4 to release the clamping effect on the profile 11; then the cut profile 11 is pushed to the right (the pushing method is not limited and is the existing technology). After the profile 11 is separated from the bracket 9, the rotating plate 101 is driven to rotate downward by controlling the cylinder 2 104. The profile 11 falls along the rotating plate 101 under the action of its own gravity, thereby realizing the blanking function of the tail material.
