Description

Technical Field

[0001] The present invention relates to steel structure cutting technology, and specifically to a large-size steel structure cutting device. Background Art

[0002] Flame cutting is a common method for rough machining of steel structure workpieces. Flame cutting is also known as gas cutting. Traditionally, acetylene gas was used for cutting, later propane, and now natural gas cutting has emerged. Due to the characteristics of rich reserves, low price, and pollution-free of natural gas, it has become the first choice for flame cutting. When cutting steel structure workpieces, it is necessary to ensure that the cutting nozzle is perpendicular to the surface of the workpiece. If the cutting nozzle is not perpendicular to the surface of the workpiece, there are risks such as cutting nozzle backfire, cutting nozzle blockage, local overheating and deformation of the workpiece, and cutting size deviation, which reduces the cutting quality and efficiency.

[0004] Existing cutting devices are generally not convenient for users to adjust the relative position between the workpiece in the clamped state and the cutting nozzle. When it is necessary to adjust the perpendicularity between the workpiece and the cutting nozzle, users usually can only adjust the posture by re-clamping the workpiece, which is time-consuming and laborious and affects the smooth progress of cutting. Therefore, a large-size steel structure cutting device is proposed. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Please refer to Figures 1-3 , an embodiment of the present invention provides a technical solution: including a cutting mechanism 100 and an adjusting mechanism 200.

[0031] Specifically, the cutting mechanism 100 includes a base 101, a hanging frame 102 is installed in the middle of the surface of the base 101, and a cutting torch 103 that can move along the hanging frame 102 is installed on the hanging frame 102. The steel structure workpiece is cut by the cutting torch 103, and the end of the cutting torch 103 is connected to an external oxygen and acetylene gas tank through a gas pipe.

[0032] The adjusting mechanism 200 includes a position adjusting member 201 arranged on the base 101, a clamping member 202 is installed on the top of the position adjusting member 201, and a positioning member 203 is arranged on one side of the clamping member 202.

[0033] Further, the position adjusting member 201 includes vertical plates 201a fixed on both sides of the surface of the base 101. A first lead screw 201b penetrates through the inside of one vertical plate 201a, and a sliding seat 201c is installed on the first lead screw 201b.

[0034] The clamping member 202 includes a clamping table 202a fixed on the sliding seat 201c. Positioning plates 202b are fixedly arranged on both sides of the clamping table 202a. A turntable 202c is movably installed on the inner side of one positioning plate 202b. A second lead screw 202d penetrates through the inside of the other positioning plate 202b. A clamping plate 202e is fixedly arranged at the end of the second lead screw 202d. The outside of the second lead screw 202d is in threaded cooperation with a lead screw sleeve 202f. The lead screw sleeve 202f is movably installed on the positioning plate 202b on the same side as the second lead screw 202d, and a gear ring 202g is arranged on the periphery of the lead screw sleeve 202f.

[0035] The positioning member 203 includes a dial tooth 203a movably installed on the positioning plate 202b.

[0036] Furthermore, a chute 101a matching the sliding seat 201c is opened on the surface of the base 101. The sliding seat 201c can slide in the chute 101a. At the same time, the sliding seat 201c and the first lead screw 201b are in threaded cooperation. Thus, under the rotation of the first lead screw 201b, the sliding seat 201c can be driven to move in the chute 101a, so as to adjust the relative position between the clamping member 202 and the cutting torch 103, so as to meet the cutting needs of users for different positions of the steel structure workpiece.

[0037] There is a snap - fit between the shifting tooth 203a and the gear ring 202g. Thus, the rotation of the wire sleeve 202f can be locked by the shifting tooth 203a. When the second lead screw 202d rotates, under the relative rotation of the second lead screw 202d and the wire sleeve 202f, the positioning plate 202b is driven to move, so as to adjust the distance between the two positioning plates 202b and realize the clamping of different steel - structure workpieces.

[0038] During use, the user first places the steel - structure workpiece to be cut on the clamping table 202a, and then rotates the second lead screw 202d. The second lead screw 202d drives the clamping plate 202e to move towards the turntable 202c in cooperation with the wire sleeve 202f to realize the clamping of the steel - structure workpiece. Subsequently, according to the cutting position of the steel - structure workpiece, the user rotates the first lead screw 201b, so that the sliding seat 201c moves in the sliding groove 101a to adjust the relative position between the steel - structure workpiece and the cutting torch 103. After the adjustment is completed, the valve on the cutting torch 103 is opened to perform the cutting operation.

[0039] In summary, through the setting of the clamping member 202, the clamping needs of steel - structure workpieces of different sizes can be met. At the same time, through the slidable setting of the position - adjusting member 201 and the cutting torch 103, the adjustable cutting position of the steel - structure workpiece is realized, reducing the limitation of the device use and meeting the different cutting requirements of the steel - structure workpiece.

[0040] Please refer to Figures 1-5 , the embodiment of the present invention provides a technical solution: including a switching member 204.

[0041] Specifically, the adjusting mechanism 200 further includes a switching member 204 arranged outside the positioning member 203.

[0042] Furthermore, the switching member 204 includes a sleeve 204a sleeved on the outside of the second screw rod 202d, the sleeve 204a can slide along the axial direction of the second screw rod 202d, and two movable rods 204c are arranged in a circular array on one end surface of the sleeve 204a, the two movable rods 204c are fixed to the sleeve 204a, and at the same time, a movable groove 204d is opened on the outer wall of the movable rod 204c, and the two ends of the movable groove 204d are connected to the swing groove 204e. The interior of the two swing grooves 204e is provided with a return spring 204f, and the sleeve 204a and its adjacent positioning plate 2 A positioning spring 204b is also provided between 02b, and the positioning spring 204b can support the sliding sleeve 204a through its own elastic force to maintain the initial position of the sliding sleeve 204a and ensure that the sliding sleeve 204a can be reset after moving. A positioning rod 204g is also provided on the outside of the sliding sleeve 204a. The positioning rod 204g adopts a deformable setting. Two protrusions are provided on the positioning rod 204g. At the same time, a bayonet that cooperates with the protrusion is also provided on the outer wall of the sliding sleeve 204a. Therefore, with the cooperation of the protrusion and the bayonet, the sliding sleeve 204a can be positioned after moving, so as to facilitate the smooth progress of subsequent operations.

[0043] A push post 203b is fixedly provided on the inner wall of the shifting tooth 203a, and the push post 203b extends into the movable groove 204d. At the same time, the push post 203b can be slidably matched with the movable groove 204d or the swing groove 204e respectively.

[0044] Preferably, the movable groove 204d is axially arranged along the movable rod 204c. When the push column 203b is located in the middle section of the movable groove 204d, it is restricted by the groove wall of the movable groove 204d and the push column 203b can only move axially along the movable rod 204c, thereby realizing the rotation locking of the shift tooth 203a. At this time, the fixed shift tooth 203a further realizes the rotation restriction of the wire sleeve 202f through the cooperation with the gear ring 202g, and then when the second screw rod 202d rotates, through the relative rotation between the second screw rod 202d and the wire sleeve 202f, the second screw rod 202d can move axially relative to the wire sleeve 202f, thereby driving the movement of the splint 202e to realize the clamping function of the steel structure workpiece.

[0045] Further, the two swing slots 204e are perpendicular to the moving slot 204d, and the extending directions of the two swing slots 204e are opposite. With the setting of the swing slots 204e, when the movable rod 204c moves axially with the sliding sleeve 204a and the push column 203b on the shifting tooth 203a moves relatively to either end of the moving slot 204d, the push column 203b can move towards the swing slot 204e direction. Thus, the shifting tooth 203a can swing in a certain direction. At this time, with the shiftable setting of the shifting tooth 203a, the locking of the wire sleeve 202f is released. Therefore, when the second lead screw 202d rotates again, the wire sleeve 202f can rotate synchronously with the second lead screw 202d. At this time, the rotation of the second lead screw 202d will no longer drive the clamping plate 202e to move horizontally, but is converted to drive the clamping plate 202e to rotate synchronously. Furthermore, with the cooperation of the clamping plate 202e and the turntable 202c, the workpiece can be rotated with the rotation of the clamping plate 202e, thereby achieving the purpose of adjusting the posture of the workpiece and ensuring that the surface of the workpiece is perpendicular to the cutting nozzle.

[0046] Furthermore, with the reverse setting of the two swing slots 204e, when the push column 203b is in any one of the swing slots 204e, the shifting tooth 203a can only swing in one direction and can be quickly reset under the action of the return spring 204f. That is, with the respective cooperation of the shifting tooth 203a and the two swing slots 204e, the shifting tooth 203a and the gear ring 202g can be approximately a ratchet mechanism with adjustable rotation direction. Thus, the user can select the swing direction of the shifting tooth 203a according to the specific posture of the workpiece to ensure the stability of the workpiece during the posture adjustment process.

[0047] When in use, when the sliding sleeve 204a is in the initial position, the shifting tooth 203a cannot rotate, so that the wire sleeve 202f is in a locked state under the cooperation of the shifting tooth 203a and the gear ring 202g. Therefore, when the second screw rod 202d rotates, the second screw rod 202d and the wire sleeve 202f rotate relative to each other, so that the clamping plate 202e can translate along with the second screw rod 202d, thereby cooperating with the turntable 202c to clamp the workpiece. When the posture of the workpiece needs to be adjusted so that the workpiece and the cutting nozzle are in a vertical state, the user can move the sliding sleeve 204a as needed, adjust the relative position between the push column 203b and the movable rod 204c, and make the push column 203b move to the movable rod 204c When the user pulls the sleeve 204a outward, the push post 203b moves to the swing groove 204e on the outer end of the movable rod 204c, so that the shifting tooth 203a can rotate counterclockwise, thereby the sleeve 202f is in a state of clockwise rotation and counterclockwise locking, that is, the second screw rod 202d can rotate clockwise to rotate the workpiece posture, and through this arrangement, when the center of gravity of the workpiece deviates to the left and needs to be adjusted clockwise, the counterclockwise locking of the sleeve 202f can support the workpiece and prevent the workpiece from suddenly turning over under the action of gravity;

[0048] On the contrary, when the user pushes the sliding sleeve 204a inward, the push column 203b moves to the swing groove 204e on the inner end of the movable rod 204c. At this time, the shifting tooth 203a can rotate clockwise, so that the wire sleeve 202f is in a state of counterclockwise rotation and clockwise locking, that is, the workpiece can adjust its posture by counterclockwise rotation. At the same time, when the center of gravity of the workpiece is biased to the right and needs to be adjusted counterclockwise, the clockwise locking of the wire sleeve 202f can support the workpiece, and can also prevent the workpiece from suddenly flipping over under the action of gravity.

[0049] In summary, through the cooperation between the positioning member 203 and the switching member 204, the cooperation state between the wire sleeve 202f and the second screw rod 202d can be switched. Under the rotation of the second screw rod 202d, different workpieces can be clamped, and the posture of the workpiece can be adjusted as needed, so that the cutting surface of the workpiece is perpendicular to the cutting nozzle to ensure cutting quality and cutting efficiency.

[0050] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
