Abstract
Description
Technical Field
[0001] This application relates to the field of square tube cutting technology, specifically a positioning device for cutting square and rectangular tubes. Background Technology
[0002] In practical applications, square and rectangular tubes often require the use of a cutting machine to cut them.
[0003] When cutting rectangular tubes, the tube is placed on a base, with one side of the tube pressed against a rotating support to adjust its angle. A clamping device then secures the tube, preventing it from moving during cutting. However, the base of the cutting machine is small, and rectangular tubes are typically long. Therefore, a significant portion of the tube extends beyond the base during cutting, causing it to tilt. To address this, the end of the tube furthest from the base is usually raised to align it parallel to the base. However, depending on the specific needs, rectangular tubes may be cut at an angle or perpendicularly. While rotating the support adjusts the tube's angle, the raised object cannot move with it, hindering continuous cutting operations.
[0004] Therefore, this application provides a positioning device for cutting square and rectangular tubes to solve the above problems. Utility Model Content
[0005] This application provides a positioning device for cutting rectangular tubes, aiming to solve the problems mentioned in the background art, such as raising the end of the rectangular tube away from the base to make the rectangular tube parallel to the base, but the cutting of the rectangular tube may be diagonal or vertical due to actual needs, so the placement angle of the rectangular tube can be adjusted by rotating the support, but the raised object cannot move with it, thus affecting the continuous cutting operation of the rectangular tube.
[0006] To achieve the above objectives, this application provides the following technical solution: a positioning device for cutting square and rectangular tubes, which is applied to a cutting device, a base set at the bottom of the cutting device for placing square and rectangular tubes, a rotating support set at the top of the base for closely abutting the square and rectangular tubes, and a pressing device set at the top of the base for pushing the square and rectangular tubes.
[0007] To enable the linkage between the rotating backrest and the support assembly: a support assembly for keeping the rectangular tube horizontal is provided on one side of the base, a fixing member for fixing the rectangular tube is provided at the top of the support assembly, a linkage assembly for driving the support assembly to move synchronously is provided on one side of the rotating backrest, and a mounting block for connecting with the linkage assembly is provided on the outer wall of the rotating backrest. By pressing the locking block, the insert block is inserted into the slot of the mounting block. Under the push of the elastic block's restoring force, the locking block is inserted into the locking hole, completing the fixed connection between the rotating support and the linkage rod. Then, the guide frame is fitted onto the outside of the linkage rod, keeping the support block moving linearly along the linkage rod. By placing the rectangular tube in the placement slot of the support block, and by rotating the turntable, the extrusion plate pushes the rectangular tube to move under the meshing action of the threaded rod and the threaded hole, thereby fixing the rectangular tube in the placement slot. This ensures the stability of the rectangular tube during cutting. At the same time, when rotating the rotating support, the linkage component fixedly connected to the rotating support moves synchronously. Under the action of the guide frame being fixedly connected to the support block, the support block rotates synchronously, thus keeping the rectangular tube horizontal at all times when rotating the rotating support.
[0008] Preferably, to facilitate the connection between the rotating support and the linkage component: the outer wall of the rotating support is fixedly connected to one side of the mounting block, the bottom end of the mounting block has a through slot, and the inner wall of the through slot has a locking hole. By inserting the connector into the through slot, a quick connection between the rotating support and the linkage component is achieved.
[0009] Preferably, to facilitate the linkage between the rotating support and the linkage component: the linkage component includes a linkage rod disposed on one side of the rotating support for driving the support component, and a connector disposed at the top of the linkage rod for connecting with the mounting block. By inserting the connector into the mounting block, the rotating support drives the mounting block, thereby linking the linkage rod.
[0010] Preferably, to maintain the stability of the connection between the connector and the mounting block: the connector includes a plug fixed to the top of the linkage rod for insertion into the slot, locking blocks inserted on both sides of the plug for insertion into the locking hole, a baffle fixed to one end of the locking block for limiting the movement of the locking block, and an elastic block disposed on the side of the baffle away from the locking block for pushing the baffle. The plug has a cavity inside for mounting the baffle and the elastic block, and the inner wall of the cavity has a through hole for inserting the locking block. The restoring force of the elastic block pushes the baffle, causing the locking block to move, thus maintaining the locking block stably inserted into the locking hole and ensuring the stability of the connection between the connector and the mounting block.
[0011] Preferably, to facilitate the pulling of the rectangular tube: the support assembly includes a support block disposed on one side of the linkage rod for supporting the rectangular tube, and a roller disposed at the bottom end of the support block to facilitate the movement of the support block. A guide frame for sleeved on the outside of the linkage rod is fixedly connected to the side of the support block near the linkage rod. The rotation of the roller at the bottom end of the support block facilitates the movement of the support block, and the guide frame sleeved on the outside of the linkage rod guides the movement of the support block, thereby keeping the rectangular tube close to the rotating support for linear movement when pulling it out.
[0012] Preferably, to facilitate the rotation of the roller: the bottom end of the support block has a rotating groove for mounting the roller, and a round rod for sleeved on the inner wall of the rotating groove is fixedly connected. By sleeved on the outside of the round rod, the roller is kept rotating within the rotating groove.
[0013] Preferably, to facilitate the fixing of the rectangular tube at the top of the support block: the top of the support block has a placement groove for placing the rectangular tube, and one side of the placement groove has a threaded hole. The fixing component includes a threaded rod threaded through the threaded hole, a pressing plate fixedly disposed at one end of the threaded rod for pushing the rectangular tube, and a turntable fixedly disposed at the other end of the threaded rod for hand gripping. By rotating the threaded rod, the pressing plate pushes the rectangular tube, fixing the rectangular tube in the placement groove and preventing the rectangular tube from moving.
[0014] This application utilizes a design incorporating a rotating support, a support assembly, a linkage assembly, a mounting block, and a guide frame. By pressing the locking block, the insert block is inserted into the slot of the mounting block. Under the push of the elastic block's restoring force, the locking block is inserted into the locking hole, completing the fixed connection between the rotating support and the linkage rod. The guide frame is then fitted over the linkage rod, ensuring the support block moves linearly along the linkage rod's direction. By placing the rectangular tube in the placement slot of the support block, rotating the turntable causes the extrusion plate to push the rectangular tube, thus fixing it in place within the slot. This ensures the stability of the rectangular tube during cutting. Simultaneously, rotating the rotating support causes the linkage assembly fixedly connected to it to move synchronously. The guide frame, fixedly connected to the support block, also drives the support block to rotate synchronously, ensuring the rectangular tube remains horizontal even when rotating the rotating support.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] This embodiment provides a positioning device for cutting square and rectangular tubes, such as... Figure 1-6 As shown, the positioning device is applied to the cutting device 1, the base 2 set at the bottom of the cutting device 1 for placing the square and rectangular tube, the rotating support 3 set at the top of the base 2 for closely pressing against the square and rectangular tube, and the extrusion device 4 set at the top of the base 2 for pushing the square and rectangular tube.
[0025] To enable the linkage between the rotating support 3 and the support component 5: a support component 5 for keeping the rectangular tube horizontal is provided on one side of the base 2, a fixing part 6 for fixing the rectangular tube is provided at the top of the support component 5, a linkage component 7 for driving the support component 5 to move synchronously is provided on one side of the rotating support 3, and a mounting block 8 for connecting with the linkage component 7 is provided on the outer wall of the rotating support 3. By pressing the locking block 722, the insert block 721 is inserted into the slot of the mounting block 8. Under the push of the restoring force of the elastic block 724, the locking block 722 is inserted into the locking hole, completing the fixed connection between the rotating support 3 and the linkage rod 71. Then, the guide frame 9 is fitted onto the outside of the linkage rod 71, keeping the support block 51 moving linearly along the direction of the linkage rod 71. By placing the rectangular tube in the placement slot of the support block 51, by rotating the turntable 63, the extrusion plate 62 pushes the rectangular tube to move under the mutual meshing action of the threaded rod 61 and the threaded hole, thereby fixing the rectangular tube in the placement slot, thus ensuring the stability of the rectangular tube during cutting. At the same time, when rotating the rotating support 3, it drives the linkage component 7 fixedly connected to the rotating support 3 to move synchronously. Under the action of the fixed connection between the guide frame 9 and the support block 51, the support block 51 is driven to rotate synchronously, so that the rectangular tube can still be kept horizontal when rotating the rotating support 3.
[0026] Furthermore, the cutting device 1, base 2, rotating support 3, and extrusion device 4 constitute the existing steel cutting machine. The extrusion device 4 is used in the existing technical field. By pressing the steel tightly against the rotating support 3, the extrusion device 4 and the rotating support 3 cooperate to clamp and fix the square and rectangular tubes. Then, the cutting device 1 is moved to cut the square and rectangular tubes.
[0027] Specifically, to facilitate the connection between the rotating support 3 and the linkage component 7: the outer wall of the rotating support 3 is fixedly connected to one side of the mounting block 8, and the bottom end of the mounting block 8 is provided with a through slot, the inner wall of which is provided with a locking hole. By inserting the connector 72 into the through slot, the rotating support 3 and the linkage component 7 can be quickly connected. The size of the through slot is adapted to the size of the insert block 721, the size of the locking hole is adapted to the size of the locking block 722, and the mounting block 8 is welded and fixed to the side of the rotating support 3 away from the pressing device 4.
[0028] More specifically, to facilitate the linkage between the rotating support 3 and the linkage component 7: the linkage component 7 includes a linkage rod 71 disposed on one side of the rotating support 3 for driving the support component 5, and a connector 72 disposed at the top of the linkage rod 71 for connecting with the mounting block 8. By inserting the connector 72 into the interior of the mounting block 8, the linkage rod 71 is linked by rotating the support 3 to drive the mounting block 8.
[0029] Furthermore, to maintain the stability of the connection between the connector 72 and the mounting block 8: the connector 72 includes an insert 721 fixed to the top of the linkage rod 71 for insertion into the slot, a locking block 722 inserted on both sides of the insert 721 for insertion into the locking hole, a baffle 723 fixed to one end of the locking block 722 for limiting its movement, and an elastic block 724 on the side of the baffle 723 away from the locking block 722 for pushing the baffle 723. The insert 721 has a cavity inside for mounting the baffle 723 and the elastic block 724, and the inner wall of the cavity has a through hole for inserting the locking block 722. The restoring force of the elastic block 724 pushes the baffle 723, causing the locking block 722 to move, thus maintaining the locking block 722 stably inserted into the locking hole and ensuring the stability of the connection between the connector 72 and the mounting block 8. The bottom end of the insert block 721 is welded and fixed to the top end of the linkage rod 71. The size of the locking block 722 is adapted to the size of the through hole, and the through hole and the locking hole are the same size. The size of the baffle 723 is 1.2 times the size of the through hole. The elastic block 724 is an elastic rubber block that is always kept in a compressed state in the cavity. The contact part between the locking block 722 and the baffle 723 is welded and fixed. Two baffles 723 are provided, and the elastic block 724 is provided on the opposite side of the two baffles 723.
[0030] Specifically, to facilitate the pulling of the rectangular tube: the support assembly 5 includes a support block 51 on one side of the linkage rod 71 for supporting the rectangular tube, and a roller 52 on the bottom of the support block 51 to facilitate its movement. A guide frame 9 is fixedly connected to the side of the support block 51 near the linkage rod 71 for fitting around the outside of the linkage rod 71. The roller 52 at the bottom of the support block 51 rotates to facilitate its movement, and the guide frame 9, fitted around the linkage rod 71, guides the movement of the support block 51, thus keeping the rectangular tube close to the rotating support 3 for linear movement when it is pulled out.

By fitting the roller 52 onto the outside of the round rod 53, the roller 52 is kept rotating within the rotating groove. The round rod 53 is fixedly connected to the rotating groove by bolts, and the roller 52 is fitted onto the outer wall of the round rod 53, maintaining the rotation of the roller 52.
[0032] Specifically, to facilitate the fixing of the rectangular tube at the top of the support block 51: the top of the support block 51 has a placement groove for placing the rectangular tube, and a threaded hole is provided on one side of the placement groove. The fixing member 6 includes a threaded rod 61 threaded through the threaded hole, a pressing plate 62 fixedly disposed at one end of the threaded rod 61 for pushing the rectangular tube, and a turntable 63 fixedly disposed at the other end of the threaded rod 61 for hand gripping. By rotating the threaded rod 61, the pressing plate 62 is driven to push the rectangular tube, fixing the rectangular tube in place in the placement groove and preventing the rectangular tube from moving. The threads on the inner wall of the threaded hole mesh with the threads on the outer wall of the threaded rod 61. The extrusion plate 62 is fixedly welded to the end of the threaded rod 61 facing the placement groove. The turntable 63 is fixedly welded to the end of the threaded rod 61 facing away from the support block 51. The side of the placement groove away from the threaded hole is flush with the side of the rotating support 3 that is in close contact with the rectangular tube. The bottom end of the inner wall of the placement groove is flush with the top end of the base 2. The rectangular tube is placed in the placement groove. Then, by rotating the threaded rod 61, the extrusion plate 62 pushes the rectangular tube. With the combined action of the extrusion plate 62 and the placement groove, the rectangular tube is fixed, while keeping the rectangular tube in close contact with the rotating support 3 and placed in parallel.
