[0002] Aluminum profile straightening machine is a kind of equipment specially used for straightening aluminum profiles. During the processing of aluminum profiles, due to the material itself or the processing technology, the aluminum profile may have shape problems such as bending and twisting. At this time, it is necessary to use an aluminum profile straightening machine for straightening and correction. The working principle of the aluminum profile straightening machine is to utilize the plastic deformation characteristics of the material when it is subjected to force. By applying external force to the aluminum profile, the internal stress is redistributed to achieve the straightening effect. The straightening machine generally includes a front clamping mechanism and a rear clamping mechanism to work together to straighten the aluminum profile. During the clamping process, the position of the front clamping mechanism or the rear clamping mechanism needs to be locked.

[0003] However, the locking methods of the existing locking structure mainly include latch type and hook type. Due to structural and force reasons, the front clamping mechanism and the rear clamping mechanism of the straightening machine cannot be locked at any position and can only be locked at a preset fixed position. As a result, during the clamping process, the length of the aluminum profile may not be accurately matched. Sometimes the clamped material may be too long, and sometimes it may be too short, making it impossible to achieve fine adjustment, which affects production efficiency and leads to a decrease in the yield of finished products.

[0030] like Figure 1-5 As shown, a locking structure in one embodiment of the utility model includes a sliding structure 1 and a lifting structure 2. A sliding rail 11 is arranged on the outer side of the sliding structure 1. A positioning rack 12 is arranged on the sliding rail 11. The device to be locked can slide on the sliding structure 1. The lifting structure 2 abuts against the sliding structure 1. The lifting structure 2 includes a lifting plate 21 and a lifting cylinder 22. The lifting cylinder 22 is fixedly connected to the lifting plate 21. One end of the lifting cylinder 22 is fixedly connected to the device to be locked. A sliding rack 23 is arranged at the lower end of the lifting plate 21. The sliding rack 23 is meshed with the positioning rack 12. The sliding rack 23 can The lifting plate 21 can be precisely controlled by the extension and retraction of the lifting cylinder 22, thereby ensuring the stable abutment between the sliding rack 23 and the positioning rack 12, and preventing loosening or displacement during the locking process. The cooperation between the sliding rack 23 and the positioning rack 12 can achieve precise locking of the sliding structure 1. The sliding rack 23 can abut against the positioning rack 12 at different positions, thereby achieving locking at any position, making the locking position more accurate, avoiding the position deviation problem that may exist in the traditional locking method, and improving the processing accuracy of the straightening machine.

[0031] As a preferred embodiment of the utility model, it may also have the following additional technical features: the lifting cylinder 22 includes a cylinder body 221, a piston head 222 and a piston rod 223, the piston head 222 is arranged in the cylinder body 221, one end of the piston rod 223 is connected to the piston head 222, and the end of the piston rod 223 away from the piston head 222 protrudes outside the cylinder body 221 and is fixedly connected to the device to be locked, thereby realizing precise control of the lifting plate 21, ensuring the accurate docking of the sliding rack 23 and the positioning rack 12, and improving the reliability and stability of the locking structure.

[0032] As a preferred embodiment of the utility model, it may also have the following additional technical features: a movable groove 2231 is provided at one end of the piston rod 223 away from the piston head 222, and a movable steel ball 2232 is movably connected in the movable groove 2231, and the diameter of the movable groove 2231 is larger than the diameter of the movable steel ball 2232. The movable steel ball 2232 partially protrudes out of the notch of the movable groove 2231, so that rolling friction is formed between the steel ball and the contact surface, which can significantly reduce the friction between the piston rod 223 and the device to be locked, reduce wear, and thus extend the service life. At the same time, the rolling characteristics of the movable steel ball 2232 make the piston rod 223 more stable during the extension and retraction process, reduce the vibration and noise caused by friction, improve the movement performance of the lifting cylinder 22, and provide a certain guiding and positioning effect for the piston rod 223 during the extension and retraction process, which helps to ensure the accuracy of the movement trajectory of the piston rod 223 and prevent deviation.

[0034] As a preferred embodiment of the utility model, it may also have the following additional technical features: a ball bearing 2234 is sleeved on the outer wall of the piston rod 223, and the ball bearing 2234 is fixedly connected to the cylinder body 221. The ball bearing 2234 significantly reduces the friction coefficient between the piston rod 223 and the cylinder body 221 through its internal rolling friction, reduces energy loss, and extends the service life of the piston rod 223 and the cylinder body 221, thereby improving the durability of the entire lifting cylinder 22. The rolling motion of the ball bearing 2234 makes the piston rod 223 more stable during the extension and retraction process, reduces the vibration and noise caused by friction, and helps to improve the working performance of the lifting cylinder 22.

[0035] As a preferred embodiment of the utility model, it may also have the following additional technical features: an air inlet 2211 and an air outlet 2212 are provided on the cylinder body 221, and a silencer bolt 2213 is provided on the air inlet 2211 and the air outlet 2212, and the silencer bolt 2213 can reduce the noise generated when the gas passes through the air inlet 2211 and the air outlet 2212.

By setting the sensing component 224, it is used to collect the signal of the movement of the piston rod 223 relative to the cylinder body 221, and the movement signal of the piston rod 223 can be collected, so as to determine whether the piston rod 223 has moved into place, which is convenient for automation.

[0038] As a preferred embodiment of the utility model, it may also have the following additional technical features: the sensing component 224 includes a gasket 2241 and a magnetic part 2242, the gasket 2241 is connected to the magnetic part 2242, and the end of the magnetic part 2242 away from the gasket 2241 is connected to the piston head 222, the gasket 2241 is used to support and limit the position of the magnetic part 2242 on the piston rod 223, and a magnetic signal is used as the sensing signal. In this embodiment, a slot 2214 for placing a magnetic switch is opened on the cylinder body 221 along the movement direction of the piston rod 223, and the magnetic switch is set on the slot 2214 to collect the signal of the magnetic part 2242, and the collected signal is sent to the remote controller, thereby detecting the movement of the piston rod 223.

[0039] The working process of the locking structure of this embodiment is as follows: when it is necessary to lock the device to be locked, start the lifting cylinder 22, and the piston head 222 moves upward or downward along the inner wall of the cylinder body 221 under the push of air pressure, driving the piston rod 223 to perform corresponding telescopic movement. Since the piston rod 223 is fixedly connected to the device to be locked, this movement will drive the device to be locked to move to the locked position. As the device to be locked moves, the sliding rack 23 gradually approaches the positioning rack 12 and finally docks with it. When the sliding rack 23 completely slides into the positioning rack 12 and fits tightly with it, the device to be locked reaches the locked position. At this time, the lifting cylinder 22 maintains a certain air pressure to ensure a stable locking state between the sliding rack 23 and the positioning rack 12.

[0040] The locking structure of this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In this embodiment, the locking structure can achieve fine adjustment for position locking, improve the processing accuracy and production efficiency of aluminum profiles, reduce production costs, and improve product quality.

The driving motor is started to control the connecting rod to drive the gear to rotate, and the gear meshes and moves on the positioning rack 12 to control the movement of the clamping device 3. When it moves to the appropriate position, the starting cylinder drives the lifting plate 21 to rise, so that the sliding rack 23 meshes and fixes the positioning rack 12. Through the coordinated work of the clamping device 3, the driving assembly 4 and the locking structure, the precise clamping and straightening of the aluminum profile is achieved.
