[0002] The traction beam lower profile forming tooling is a tool or device used in the profile processing process. Its main functions include: positioning and clamping, forming assistance, improving processing accuracy, improving production efficiency and consistency assurance, etc. Common types of traction beam lower profile forming tooling include: Clamp: used to fix the position of the profile. Mold: determines the shape of the profile. Disassembly block: ensures the accurate position of the profile. Support device: prevents the profile from deforming during processing, etc.

[0003] Among them, the fixture used to fix the position of the profile in the prior art basically relies on bolt assemblies or cylinders to drive the clamping plate assemblies to move and complete the positioning, clamping and fixing operations. Whether it is the bolt assembly or the cylinder assembly that drives the clamping plate assembly to move, clamp and position, there is a lack of synchronization. Adjusting each bolt assembly and cylinder assembly in sequence cannot ensure that the adjustment amount is consistent. At the same time, the adjustment in sequence is cumbersome and laborious. In addition, the inconsistent adjustment amount will also lead to different extrusion forces of each clamping plate. Uneven pressure will cause uneven deformation during the fixing process. Long-term uneven pressure may cause premature fatigue and failure, and will also cause unnecessary vibration and noise. In order to change the current situation, a traction beam lower profile forming tooling that is easy to position is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A tooling for forming the lower profile of a traction beam that is easy to position includes a tooling base 1, a plurality of movable grooves 2 are provided on the tooling base 1, a rotating cavity 15 is provided inside the tooling base 1, a driving motor 16 is provided in the rotating cavity 15, a screw 5 extending into the rotating cavity 15 is provided in the movable groove 2, the screw 5 is connected to the driving motor 16 through a rotating mechanism, a nut 6 is threadedly installed on the screw 5, there are four screws 5 and they are distributed at equal intervals in the circumferential direction, the length of the screw 5 and the initial position of the nut 6 on the screw 5 are the same, the thread direction on the screw 5 is set correspondingly, and it is ensured that when the four screws 5 rotate synchronously, the four nuts 6 move synchronously closer or farther.

[0023] A mounting frame 8 is provided on the nut 6 through an insertion mechanism, and a toggle groove 11 is provided on the mounting frame 8. A slide rod 12 is provided in the toggle groove 11, and a limit plate 13 is provided on the slide rod 12 through an elastic mechanism sliding sleeve. A limit groove corresponding to the limit plate 13 is provided on the inner wall of the movable groove 2, and a threaded groove 14 is provided on the mounting frame 8. A disassembly block 3 is installed in the inner thread of the threaded groove 14, and a clamping plate 4 is installed on the disassembly block 3. The clamping surface of the clamping plate 4 can be a plane or an arc surface, etc., which can be determined according to the different types of lower profiles of the traction beam. The clamping plate 4 is formed into a square for clamping and positioning, which is suitable for clamping and positioning of profiles with a square cross-sectional view.

[0024] The rotating mechanism includes a driving gear 17 installed on the output shaft of the driving motor 16, and a transmission gear 18 is provided at the end of the screw 5. The driving gear 17 is meshed with the transmission gear 18. As shown in the figure, the driving gear 17 and the transmission gear 18 are both bevel gears and are vertically meshed. The above components are used in combination to realize the power transmission of the driving motor 16 and realize the synchronous rotation of the four screws 5.

[0025] The plug-in mechanism includes an insert block 9 installed on the outer wall of the nut 6. A slot 10 corresponding to the insert block 9 is provided on the surface of the mounting frame 8 that contacts the nut 6. When the insert block 9 is in the slot 10, the mounting frame 8 moves on the screw rod 5 following the nut 6.

[0026] The elastic mechanism includes a spring sleeved on the outside of the slide rod 12, and both ends of the spring are elastically connected to the outer wall of the limit plate 13 and the inner wall of the toggle groove 11 respectively. The spring is not drawn in the figure, and it realizes the extrusion of the limit plate 13. As shown in the figure, the limit plate 13 is L-shaped, and its horizontal part slides through the inner wall of the toggle groove 11 and extends to the outside of the mounting frame 8, and is located in the limit groove on the inner wall of the movable groove 2. Therefore, the mounting frame 8 is vertically limited and will not be separated from the nut 6, so the plug 9 can be stably located in the slot 10.

[0027] A cross bar 7 is provided in the movable groove 2 , and the cross bar 7 is parallel to the screw rod 5 . The cross bar 7 slides through the nut 6 . The function of the cross bar 7 is to limit the nut 6 to prevent it from rotating with the screw rod 5 .

[0028] A protective pad is provided on the surface where the clamping plate 4 contacts the profile. The protective pad is made of rubber and has anti-skid patterns on the surface. The rubber protective pad protects the profile to prevent the clamping plate 4 from directly contacting its outer wall and causing friction damage. The anti-skid patterns have a good anti-skid effect and ensure the stability of the clamping positioning.

[0029] When the utility model is used, the profile is placed on the tooling base 1, and the driving motor 16 is started to drive the driving gear 17 to rotate. The driving gear 17 cooperates with the transmission gear 18 to drive multiple screws 5 to rotate synchronously. When the screw 5 rotates, the nut 6 threadedly mounted thereon will move, and the nut 6 drives the mounting frame 8 to move in the movable groove 2. The mounting frame 8 drives the disassembly block 3 and the clamping plate 4 to move, and the multiple clamping plates 4 move and gather to finally realize the clamping and positioning operation of the profile.

[0030] The protective pad on the clamping plate 4 will wear out with use. At this time, the disassembly block 3 can be rotated to disengage it from the threaded groove 14. When the disassembly block 3 is in the disassembled state, it is convenient to replace the protective pad. It can be directly torn off and replaced with a new one by adhesive installation.

[0031] In this solution, when the device needs to be transported, multiple components can be disassembled to disperse the overall weight of the device, thereby facilitating its transportation and providing convenience for the transport personnel. Specifically: move the limit plate 13 in the toggle groove 11 to make it move on the slide rod 12 and squeeze the spring. At the same time, after its horizontal part is disengaged from the limit groove on the inner wall of the movable groove 2, the mounting frame 8 can be directly removed.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
