[0002] Guide rail: A device with grooves or ridges made of metal or other materials that can bear, fix, guide and reduce friction of moving devices or equipment. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine parts, special equipment, instruments, etc. Guide rails are also called guide rails, linear guides, and linear guides. They are used in linear reciprocating motion occasions. They have higher rated loads than linear bearings and can bear certain torques. They can achieve high-precision linear motion under high loads. Since the use environment of guide rails is different, it is often necessary to select the length of the guide rail according to the use requirements.

It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a cutting device for guide rail production, comprising: an operating table 1, two limit plates 2 are fixedly installed on one side of the upper end of the operating table 1, the two limit plates 2 are symmetrically arranged on the upper end of the operating table 1, and the cutting machine is installed on the other side of the upper end of the operating table 1. The inner ends of the two limit plates 2 are rotatably connected and installed with guide wheels 3 through a rotating shaft. The guide rail passes between the two limit plates 2, and the guide wheel 3 contacts the side wall of the guide rail to guide it when the guide rail moves.

[0024] A clamping plate 4 is fixedly installed on the front end of the other side of the upper end of the operating table 1, and a guide frame 6 is fixedly installed on the rear end. A clamping block 7 is slidably connected inside the guide frame 6. Anti-slip pads 5 are fixedly installed on the inner ends of the clamping plate 4 and the clamping block 7. When clamping the guide rail, the friction between the guide rail and the guide rail is increased, so that the guide rail can be clamped more firmly.

[0025] Slide grooves 8 are provided on both sides of the inner end of the guide frame 6, and slide blocks 9 are fixedly installed on both ends of the left and right ends of the clamping block 7. One end of the slide block 9 is slidably inserted into the slide groove 8, and springs 10 are fixedly installed on both sides of the outer end of the clamping block 7. The other end of the spring 10 is fixedly installed on the inner wall of the guide frame 6. A rotating groove is provided in the middle of one end of the guide frame 6, and a driving rod 11 is rotatably connected in the rotating groove. The lower end of the driving rod 11 is rotatably connected to a push rod 12, and the lower end of the push rod 12 is rotatably connected to a push rod 21. 3. The other end of the push rod 2 13 is rotatably connected to the outer end of the clamping block 7. When cutting the guide rail, by holding the upper end of the driving rod 11 and rotating the upper end of the driving rod 11 outward, the lower end of the driving rod 11 rotates inward, and at the same time drives the push rod 12 and the push rod 2 13 to move inward, thereby pushing the clamping block 7 to slide inward. At this time, the spring 10 is in a stretched state, and the clamping block 7 clamps the guide rail. The guide rail can be cut by starting the cutting machine to avoid shaking of the guide rail when cutting the guide rail.

[0026] Fixed cylinders 14 are fixedly installed on the front and rear sides of the lower end of the operating table 1. Guide rods 16 and 17 are slidably connected in the two fixed cylinders 14 respectively. Baffles 22 are fixedly installed on the upper sides of the outer ends of guide rods 16 and 17.

[0027] A sliding hole 15 is provided on the side wall of one end of one of the fixed cylinders 14, and a shaft rod 20 is slidably connected in the sliding hole 15. The inner end of the shaft rod 20 passes through the sliding hole 15 and is fixedly installed with a tooth plate 21. The outer end of the shaft rod 20 is sleeved with a spring 21. One end of the spring 21 is fixedly installed on the outer wall of the fixed cylinder 14, and the other end is fixedly installed on the outer end side wall of the shaft rod 20. A tooth plate 18 is fixedly installed on the side wall of one end of the guide rod 16. When the spring 21 is in a balanced state, the tooth plate 18 and the tooth plate 219 are engaged with each other. A scale line is provided on the upper end side wall of the guide rod 16. When one end of the guide rail is in contact with the baffle, the position of the guide rail from the cutting machine can be known through the scale line. By starting the cutting machine, the guide rail can be cut to a length that meets the requirements.

[0028] When the length of the cutting rail needs to be adjusted, the shaft 20 is pulled outward through the compression spring 21 to separate the tooth plate 2 and the tooth plate 1 18, and the position of the baffle 22 can be adjusted to adjust the length of the cutting rail.

[0029] During actual use, the length of the lower guide rail is cut as needed, the position of the baffle 22 is adjusted, one end of the guide rail is passed through the two limit plates 2, and after passing between the clamping plate 4 and the clamping block 7, it contacts the baffle 22. Then the upper end of the driving rod 11 is rotated outward, and the lower end of the driving rod 11 is rotated inward, while driving the push rod 12 and the push rod 2 13 to move inward, thereby pushing the clamping block 7 to slide inward. At this time, the spring 10 is in a stretched state, and the clamping block 7 clamps the guide rail. The cutting machine can be started to cut the guide rail to avoid shaking of the guide rail when cutting. After the cutting is completed, the driving rod 11 is released, and the guide rail continues to be pushed forward and contacts the baffle 22, and then it can be cut again.
