Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0026] Example

[0027] refer to Figures 1 to 4 A guide rail production cutting positioning device of this embodiment includes: a base 100, support legs 200 are fixedly installed at the four corners of the top of the base 100, a top seat 900 is fixedly installed on the top of the support legs 200, a displacement mechanism 300 is fixedly installed at both ends of the top seat 900, a driving mechanism 400 is fixedly installed on the rear side of the top seat 900, the front end of the driving mechanism 400 is fixedly connected to the displacement mechanism 300, and a positioning mechanism 600 is fixedly installed on the top of the displacement mechanism 300;

[0028] The positioning mechanism 600 includes a support rod 610, which is fixedly mounted on the top of the displacement mechanism 300. A concave seat 620 is fixedly mounted on the inner side of the upper end of the support rod 610. The inner side of the concave seat 620 is rotatably connected with driving guide rollers 630 at equal intervals. A driving assembly 660 is fixedly mounted on the top of the concave seat 620. The bottom of the driving assembly 660 is fixedly connected to the top of the driving guide rollers 630 at both ends. The base 100 serves as the foundation of the entire device. The top seat 900 is firmly supported by the support legs 200 to ensure the stability and reliability of the entire device. The top seat 900 serves as an installation platform for the displacement mechanism 300 and the driving mechanism 400, providing solid support for these components. The displacement mechanism The design of 300 enables the positioning mechanism 600 to move flexibly in the horizontal direction, so as to adapt to the cutting requirements of guide rails of different lengths. The driving mechanism 400 is responsible for providing power to the displacement mechanism 300 to drive it to perform precise displacement operations. The positioning mechanism 600 is the core part of the device and is fixed to the top of the displacement mechanism 300 through the support rod 610. The concave seat 620 serves as the installation platform for the driving guide roller 630. The driving guide rollers 630 connected to the inner side thereof are rotatably connected at equal intervals, so as to stably and accurately clamp the guide rail. The setting of the driving assembly 660 enables the driving guide rollers 630 to rotate synchronously, thereby driving the guide rail to move in the horizontal direction, which facilitates the subsequent cutting operation. The driving assembly 660 60 is mainly composed of a transmission pulley 661, a base frame 662, a transmission gear 663 and a first motor 664, which work together to achieve synchronous driving of the driving guide roller 630, thereby driving the guide rail to move in the horizontal direction. Specifically, the transmission pulley 661 is rotatably connected to the top two sides of the concave seat 620, and they are connected by a transmission belt. This design makes it possible for one transmission pulley 661 to rotate synchronously when one transmission pulley 661 rotates, thereby achieving power transmission. The base frame 662 serves as a mounting platform for the transmission gear 663 and the transmission pulley 661, and the transmission gear 663 is rotatably connected to the two sides of the base frame 662. The first motor 664 is fixedly mounted on the base frame 662. On the outside of the bottom, its output end passes through the base frame 662 and is fixedly connected to the bottom of a transmission gear 663 on one side. When the first motor 664 is started, it will drive the transmission gear 663 connected to it to rotate. Since the bottom of another transmission gear 663 is fixedly connected to the top of a transmission pulley 661, this transmission gear 663 will also rotate synchronously and drive another transmission pulley 661 to rotate through the transmission belt. Through this design, the drive assembly 660 can effectively transmit the power of the first motor 664 to the driving guide roller 630, so that they rotate synchronously. When the driving guide roller 630 rotates, they will clamp and drive the guide rail to move in the horizontal direction, thereby providing convenience for subsequent cutting operations.

[0029] The driving assembly 660 includes a transmission pulley 661 and a base frame 662. Both sides of the base frame 662 are rotatably connected with transmission gears 663. The transmission pulley 661 is rotatably connected to both sides of the top of the concave seat 620. The base frame 662 is fixedly installed on one side of the top of the transmission pulley 661. The base frame 662 is arranged on the outside of the transmission pulley 661. The transmission pulleys 661 are connected through a transmission belt. A first motor 664 is fixedly installed on the outside of the bottom of the base frame 662. The output end of the first motor 664 passes through the base frame 662 and a The bottom of the side transmission gear 663 is fixedly connected, and the bottom of another transmission gear 663 is fixedly connected to the top of a transmission pulley 661; the driving assembly 660 is mainly composed of a transmission pulley 661, a base frame 662, a transmission gear 663 and a first motor 664. The transmission pulley 661 is cleverly installed on both sides of the top of the concave seat 620. Such a layout not only ensures the stable transmission of the driving force, but also makes the entire structure more compact. The base frame 662 is firmly installed on the transmission pulley 661 as a supporting and fixing component. 1, and the internal rotation is connected to the transmission gear 663, and the transmission pulleys 661 are connected by a transmission belt. This design ensures that the power can be transmitted smoothly and continuously. When the first motor 664 is started, its output end will drive the transmission gear 663 connected to it to rotate. Since the other transmission gear 663 is fixedly connected to one of the transmission pulleys 661, the rotation of this transmission gear 663 will drive the transmission pulley 661 to rotate, and then drive the other transmission pulley 661 to rotate synchronously through the transmission belt. This driving method not only ensures the stable output of the driving force, but also enables the driving guide roller 630 to rotate synchronously, thereby realizing the smooth driving of the guide rail. In addition, the setting of the base frame 662 not only enhances the structural stability of the entire driving assembly 660, but also facilitates installation and maintenance. The driving assembly 660 provides a stable and efficient driving function for the guide rail production cutting and positioning device through a reasonable mechanism design and power transmission method, so that the entire device performs well in the precise positioning and continuous cutting of the guide rail.

[0030] A base plate 640 is fixedly mounted on the top inner end of the concave seat 620, and balls 650 are rotatably connected to the top of the base plate 640 at equal intervals; the base plate 640 provides a stable mounting platform for the balls 650, ensuring that the balls 650 can maintain a stable motion trajectory during rotation, and the balls 650 are key components for reducing friction and improving positioning accuracy. They replace sliding with rolling, thereby significantly reducing the friction resistance between the guide rail and the slider 330, making the movement of the guide rail more stable and smooth, which not only helps to reduce energy loss and wear, and extend the service life of the guide rail, but also improves positioning accuracy and repeatability. In addition, the number and quality of the balls 650 also determine the load-bearing capacity and service life of the slider 330. Therefore, during the design and manufacturing process, it is necessary to strictly control the material, size and manufacturing process of the balls 650 to ensure that they have good wear resistance and durability.

[0031] The displacement mechanism 300 includes a side rail 310, which is fixedly mounted at both ends of the base 100. The side rail 310 is internally rotatably connected with a bidirectional screw rod 320. The threads at both ends of the bidirectional screw rod 320 rotate in opposite directions. The rear end of the bidirectional screw rod 320 is fixedly connected to the driving mechanism 400. Both ends of the bidirectional screw rod 320 are threadedly connected with a slider 330. The top of the slider 330 is fixedly connected to the bottom of the support rod 610. The displacement mechanism 300 is mainly composed of a side rail 310, a bidirectional screw rod 320, a slider 330 and a driving mechanism 400. The side rail 310 is fixedly mounted at both ends of the base 100, providing a stable support for the entire displacement mechanism 300. The bidirectional screw rod 320 is rotatably connected to the inside of the side rail 310. The design is ingenious, and the threads at both ends rotate in opposite directions. This design enables the sliders 330 at both ends to move in opposite directions at the same time when the bidirectional screw rod 320 rotates, thereby realizing the horizontal displacement of the positioning mechanism 600. The rear end of the bidirectional screw rod 320 is connected to the driving mechanism 400 is fixedly connected, and the bidirectional lead screw 320 can be rotated by the drive mechanism 400. The specific implementation method of the drive mechanism 400 can be a power device such as a motor and a cylinder, which provides power for the rotation of the bidirectional lead screw 320. At both ends of the bidirectional lead screw 320, there are sliders 330 threadedly connected, and the slider 330 and the bidirectional lead screw 320 are threadedly connected, so that the slider 330 can move along the lead screw under the rotation of the bidirectional lead screw 320. The top of the slider 330 is fixedly connected to the bottom of the support rod 610, so that when the slider 330 moves, it can drive the support rod 610 and the positioning mechanism 600 to move together. Through this design, the displacement mechanism 300 can convert the power of the driving mechanism 400 into the displacement of the positioning mechanism 600 in the horizontal direction, thereby realizing the precise positioning of the guide rail. At the same time, due to the special design of the bidirectional lead screw 320 and the slider 330, the displacement mechanism 300 also has high positioning accuracy and stability, which can meet the accuracy requirements of guide rail cutting.

[0032] The inner side of the side rail 310 and the overall cross-sectional shape of the slider 330 are both set to be a convex shape, and the inner side of the side rail 310 and the outer surface of the slider 330 are fixedly connected with wear-resistant gaskets; firstly, the inner side of the side rail 310 and the overall cross-sectional shape of the slider 330 are both set to be a convex shape. This design not only enhances the stability and rigidity of the structure, but also makes the movement of the slider 330 in the side rail 310 more stable and smooth. The convex cross-sectional shape can provide better guidance and positioning effects, reduce the shaking and deviation caused by movement, thereby improving the positioning accuracy. Secondly, the wear-resistant gaskets are fixedly connected to the inner side of the side rail 310 and the outer surface of the slider 330. The main function of the wear-resistant gaskets is to Reduce friction and wear, and increase service life. During the movement of the slider 330 in the side rail 310, the wear-resistant gasket can effectively reduce the friction coefficient, reduce energy loss and heat generation, and protect the surface of the side rail 310 and the slider 330 from wear. This not only ensures the long-term stable operation of the device, but also reduces maintenance costs. In addition, the material and thickness of the wear-resistant gasket are also carefully selected. They are usually made of highly wear-resistant and highly elastic materials to ensure that they can still maintain good performance under long-term and high-frequency use. At the same time, the thickness of the gasket also needs to be moderate, which is necessary to ensure sufficient wear resistance while avoiding assembly difficulties or inflexible movement caused by excessive thickness.

[0033] The driving mechanism 400 includes a side plate 430 and a worm wheel 420. The side plate 430 is fixedly mounted on both ends of the back side of the base 100. A second motor 440 is fixedly mounted on the outer side of one side plate 430. The output end of the second motor 440 passes through one side plate 430 and is fixedly mounted with a connecting shaft 450. The connecting shaft 450 is rotatably connected between the inner sides of the two sets of side plates 430. Both ends of the connecting shaft 450 are fixedly mounted with a worm 410. The worm wheel 420 is rotatably connected to both sides of the back side of the base 100. The front side of the worm wheel 420 is fixedly connected to the rear end of the bidirectional lead screw 320. The driving mechanism 400 mainly consists of the side plate 430, the worm wheel 420, the second motor 440, the connecting shaft 4 50 and worm 410 and other key components, the side plates 430 are fixedly installed at both ends of the back of the base 100, providing a stable support for other components, a second motor 440 is fixedly installed on the outer side of one side plate 430, which is the power source of the drive mechanism 400 and provides power for the entire mechanism through electric drive, the output end of the second motor 440 passes through a side plate 430, and is fixedly installed with a connecting shaft 450, which is rotatably connected between the inner sides of the two sets of side plates 430 to form a stable rotating structure, and the worm 410 is fixedly installed at both ends of the connecting shaft 450, so that when the second motor 440 is started, the connecting shaft 450 will drive the worm 410 to rotate. 10 rotates together, the worm gear 420 is rotatably connected to both sides of the back side of the base 100, and they form a worm gear 420 and worm 410 transmission pair with the worm 410. This transmission mode has a large transmission ratio and a high transmission efficiency, and can also realize a self-locking function to ensure the stability and reliability of the transmission process. The front side of the worm gear 420 is fixedly connected to the rear end of the bidirectional lead screw 320, so when the worm gear 420 rotates, it will drive the bidirectional lead screw 320 to rotate synchronously. In actual operation, when it is necessary to move the positioning mechanism 600, the control system will issue an instruction to start the second motor 440, and the second motor 440 will drive the worm 410 to rotate through the connecting shaft 450. The worm wheel 420 is then driven to rotate. Since the worm wheel 420 is fixedly connected to the bidirectional lead screw 320, the rotation of the worm wheel 420 will be converted into the rotation of the bidirectional lead screw 320. The rotation of the bidirectional lead screw 320 will drive the positioning mechanism 600 to move in the horizontal direction through the slider 330, thereby realizing the precise positioning of the guide rail. The design of this driving mechanism 400 not only has the advantages of simple structure and stable transmission, but also can realize precise electric control, thereby improving production efficiency and positioning accuracy. At the same time, the self-locking function of the worm wheel 420 and worm 410 transmission also ensures the stability of the positioning mechanism 600 after positioning, thereby avoiding positioning deviation caused by external interference.

Mounting holes 800 are provided at the four corners of the mounting frame 700. The support frame 500 fixedly installed in the middle of the back side of the base 100 not only provides a stable support for the entire device, but also ensures the stable installation of the mounting frame 700. The design of the support frame 500 takes into account the strength and stability of the structure, and can withstand the weight of the mounting frame 700 and the components it carries, while reducing vibration and shaking to ensure the stable operation of the device. The mounting frame 700 is fixed on the top of the support frame 500, which provides a stable platform for installing other necessary components or equipment. Mounting holes 800 are provided at the four corners of the mounting frame 700. This design is convenient. The installation and disassembly process makes the installation more flexible and convenient. At the same time, the setting of the mounting holes 800 also ensures the accuracy and stability of the installation, and avoids loosening or deviation caused by improper installation. These mounting holes 800 can be used to connect fixing bolts, screws or other fasteners to firmly fix the components to be installed on the mounting frame 700. In this way, the stability and reliability of the components can be ensured, and loosening or damage caused by vibration or external force can be reduced. In addition, the design of the mounting frame 700 and the mounting holes 800 also takes into account the expandability and upgradeability of the device. With the changes in production needs and the development of technology, the device may need to be upgraded or modified. By reserving the mounting holes 800, new components or equipment can be easily added to improve the performance and function of the device.

[0035] The use principle and advantages are as follows: by setting the displacement mechanism 300, during use of the device, first, the cutting device can be assisted to be installed through the mounting frame 700 at the top of the support frame 500 in conjunction with the mounting holes 800 and the bolts, and then the second motor 440 is started to operate, and the second motor 440 drives the connecting shaft 450 to drive the two groups of worm gears 410 to rotate. The two groups of worm gears 410 rotate, and because the worm gear 420 and the worm gear 410 are connected in transmission, the two groups of worm gears 420 can be synchronously driven to rotate by the two groups of worm gears 410. The worm gear 410 drives the worm gear 420 to rotate, which can assist in synchronously driving the two-way screw rods 320 inside the two groups of side rails 310 to rotate. The two-way screw rods 320 rotate and the threads at both ends thereof rotate in opposite directions. At this time, the two groups of sliders 330 can be synchronously driven to slide back and forth inside the side rails 310, and the reciprocating sliding of the sliders 330 can drive the concave seats 620 at the top of the support rod 610 to displace each other, and the concave seats 620 and the driving guide rollers 630 displace each other. , the concave seat 620 and the driving guide roller 630 can be used to assist in clamping and positioning the guide rail to be processed. At this time, by starting the first motor 664 to drive the transmission gear 663 to rotate, the transmission gears 663 will mesh and move, which can assist in the synchronous driving of the transmission pulley 661 to rotate. The transmission pulleys 661 are connected by a transmission belt transmission, and then the two sets of driving guide rollers 630 can be synchronously driven to rotate. At this time, the driving guide roller 630 on the side of the displacement guide rail rotates, which can assist in the reciprocating displacement of the drive guide rail. Since the guide rail can be driven to displace back and forth, the cutting equipment can be started at this time to cut the guide rail.
