After the cutting is completed, the fixed-distance cutting mechanism 1 pushes the guide rail 105 into the distance detection mechanism 2, and then the cut guide rail 105 is accurately detected in length. The qualified guide rail 105 and the longer guide rail 105 are then pushed into the secondary cutting and burr cutting mechanism 3 through the fixed-distance cutting mechanism 1. The secondary cutting and burr cutting mechanism 3 removes burrs from the guide rail 105 and can also perform secondary processing on the longer guide rail 105. If the guide rail 105 with a shorter length is cut, it needs to be manually removed from the equipment after the distance detection mechanism 2 alarms.

[0029] In an optional implementation manner of the embodiment of the present invention, as Figure 2-5 As shown, the fixed-distance cutting mechanism 1 includes: a lifting rod 101, a spring A102, a mounting plate 103, a vacuum suction cup 104, a guide rail 105, a guide rail contact piece 106, a support seat A107, a connecting rod group 108, a gear A109, a gear B110, a rack 111, a pressing block 112, a pressing rod 113, a fixing rod 114, a spring B115, a cylinder A116, a motor A117, a cutting blade 118, a cylinder B119 and a pushing plate 120;

[0030] The mounting plate 103 is fixed on the ground, and two lifting rods 101 are slidably installed on the top of the mounting plate 103.

The sliding rod 1083 is slidably installed on the sliding groove of the support seat A107, and the other end of the sliding rod 1083 is provided with teeth that mesh with the gear A109; manually place the guide rail 105 on the support seat A107, and then push the guide rail 105 to the guide rail contact piece 106 and push the guide rail contact piece 106 to a horizontal state. The rotation of the guide rail contact piece 106 will drive the sliding rod 1083 to move along the groove of the support seat A107, and the sliding rod 1083 will drive the gear A109 to rotate, and then drive the rack 111 to move downward along the groove of the support seat A107, driving the lower pressure block 112 downward Movement, thereby driving the cutting blade 118 to move downward until the lower end of the cutting blade 118 contacts the upper end of the guide rail 105, so as to achieve a fixed distance cutting of the guide rail each time. At this moment, the cylinder A116 drives the motor A117 and the cutting blade 118 to move downward, and the motor A117 rotates 107 to drive the cutting blade 118 to rotate and then complete the cutting work. In order to prevent the guide rail 105 from falling during the cutting process, the vacuum suction cup 104 is in a state of tightly adsorbing the guide rail 105, and after the cutting is completed, with the gravity of the guide rail 105, the lifting rod 101 follows the guide rail 105 to move downward to the contact point with the support seat A107, and then the vacuum suction cup 104 releases the guide rail 105, the lifting rod 101 resets, the cutting blade 118 resets, and then the push plate 120 pushes the guide rail 105 to the distance detection mechanism 2.

[0032] In an optional implementation manner of the embodiment of the present invention, as Figure 6-7 As shown, the distance detection mechanism 2 includes: a support base B201, a distance sensor 202, a spring C203, a slide bar 204, a clamping plate 205, a cylinder C206, a sliding positioning plate 207, a connecting rod A208, a connecting rod 209, a slider A210, a fixed block 211 and a push block 212;

[0033] A distance sensor 202 is fixed on the right side of the support seat B201, and two slide bars 204 are arranged below the distance sensor 202. The slide bars 204 are slidably mounted on the support seat B201, and a spring C203 is arranged between the slide bars 204 and the support seat B201.

[0034] The push plate 120 pushes the guide rail 105 to the position where the center of the distance sensor 202 is aligned with the center of the middle vertical plate of the guide rail 105, and then the cylinder C206 pushes the push block 212 to move away from the cylinder C206, thereby driving the connecting rod A208 to move, thereby driving the clamping plate 205 to slide leftward along the groove of the support seat B201 to clamp the left and right sides of the guide rail. The clamping plate 205 moves and drives the slider A210 and the connecting rod 209 to move leftward, and the sliding positioning plate 207 will be due to the inside of the slider A210. The guide rail 105 is clamped on the left and right sides and the side close to the cylinder by the groove and the inner groove of the fixed block 211, so as to better fix the position of the guide rail 105 and make the reading of the distance sensor 202 more accurate. The distance sensor 202 will measure the guide rail 105 according to the set distance value. If the distance is too large, it is an unqualified product and needs to be manually collected and separated from the equipment. If the distance is correct or too short, it can enter the secondary cutting and burr cutting mechanism 3.

[0035] In an optional implementation manner of the embodiment of the present invention, as Figure 8-10 As shown, the secondary cutting and burr removal mechanism 3 includes: a support seat C301, a cylinder D302, a cylinder push rod 303, a clamp 304, a plate 305, a sliding plate 306, a slider B307, a motor B308, a burr removal blade 309, a push rod assembly 310, a slider C311, a motor C312, a secondary grinding blade 313, a rotating block 314, a motor D315, a motor E316 and a push rod 317;

[0036] A cylinder D302 is fixed to the bottom of the support seat C301, and the telescopic end of the cylinder D302 is fixed to the cylinder push rod 303, and the two ends of the cylinder push rod 303 are respectively fixed to a clamp 304, and the middle position of the clamp 304 is rotatably installed on the support seat C301. The plate 305 is fixed on the ground and is set on the right side of the support seat C301.

[0037] After the measurement by the distance detection mechanism 2, secondary cutting is required. The push plate 120 pushes the qualified guide rail 105 to the support seat C301. At this moment, the cylinder D302 pushes the cylinder push rod 303 to drive the clamping claw 304 to rotate and clamp the guide rail 105. For qualified products, burrs need to be processed. The motor E316 can be slightly rotated to the lower right by about 20-30 degrees, and the push rod assembly 310 is driven to rotate to the lower right, which can drive the slider B307 to slide to the upper right along the slide groove on the sliding plate 306, so that the burr removal blade 309 contacts the cross section of the guide rail 105. While the burr removal blade 309 moves, the slider C311 will slide in the opposite direction away from the cross section of the guide rail 105. At this moment, the motor B308 starts to rotate, driving the burr removal blade 309 to rotate to grind the burrs on the cross section. The machine D315 rotates to drive the rotating block 314 to rotate along the inner groove of the push rod 317, thereby driving the sliding plate 306 and the burr removal blade 309 to slide along the plate 305 to the lower right side, so that the burr removal blade 309 can contact the entire cross-section of the guide rail 105 while rotating to complete the burr cutting. For products with longer cutting, the motor E316 rotates slightly to the upper left, so that the burr removal blade 309 separates from the cross-section of the guide rail 105, and the secondary grinding blade 313 contacts the cross-section of the guide rail 105. At the same time, the motor C312 rotates to drive the secondary grinding blade 313 to cut the cross-section. At the same time, the motor D315 rotates to the upper left, thereby driving the sliding plate 306 and the secondary grinding blade 313 to slide along the plate 305 to the upper left, so that the secondary grinding blade 313 can contact the entire cross-section of the guide rail 105 while rotating and cutting to complete the secondary cutting.
