[0023] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0024] Reference Figures 1 to 5The embodiment of the present invention is a length detector with a fixed structure, which includes a base plate 1, the upper surface of the base plate 1 is fixedly connected to the support leg 11, the upper surface of the support leg 11 is fixedly connected to the workbench 12, the upper surface of the workbench 12 is provided with a V-shaped groove running through one side, the bottom of the V-shaped groove runs through the workbench 12, and the upper surface of the workbench 12 is provided with a blanking inclined platform 10, the upper surface of the workbench 12 is fixedly connected to the second servo cylinder 13 away from the V-shaped groove, the output end of the second servo cylinder 13 is fixedly connected to the second piston rod 14, the second piston rod 14 is fixedly connected to the push plate 15 away from the second servo cylinder 13, and the push plate 15 is provided with a baffle 16 near the blanking inclined platform 10, and a controller 17 is provided on the upper surface of the workbench 12, the edge of the upper surface of the workbench 12 near the through end of the V-shaped groove is fixedly connected to the support rod 9, the support rod 9 is L-shaped, and the lower surface of the horizontal part of the support rod 9 is fixedly connected to the laser detector 19, and a defective frame 2 and a good frame 18 are provided on the upper surface of the base plate 1. The defective frame 2 is below the through opening of the V-shaped groove The width of the top of the V-groove should be greater than the diameter of the tubular part. The detection laser emitted by the detection end of the laser detector 19 is aimed at the through-hole in the center of the V-groove. When the tubular part just starts to pass through the detection laser, the laser detector 19 will transmit this signal to the controller 17. The controller 17 judges the length of the tubular part based on the distance that the second servo cylinder 13 drives the push plate to move at this time. If the length of the tubular part meets the requirements, the second servo cylinder 13 is driven to drive the push plate back to its original position, and the servo motor 3, the first cylinder 5, and the air pump 801 are driven to clamp the qualified tubular part and transport it to the good product frame 18. If the length of the tubular part does not meet the requirements, the second servo cylinder 13 is driven to drive the push plate to continue moving, and the unqualified tubular part is pushed into the defective frame 2, and then returns to its original position. The baffle 16 can block other materials to be inspected on the unloading ramp 10 during the movement of the push plate. Multiple tubular parts to be inspected can be placed on the unloading ramp 10 at the same time, thereby reducing the frequency of workers loading materials.

[0025] The first piston rod 6 is away from the first servo cylinder 5 and fixedly connected to a movable plate 7 , on which a fixed clamping mechanism 8 is provided.

[0026] The fixed clamping mechanism 8 includes an air pump 801, a vent pipe 802, a fixed plate 803, a fixed sleeve 804, a spring 805, a sliding shaft 806 and a pressure plate 807. There are two fixed plates 803, fixed sleeves 804, springs 805, sliding shafts 806 and pressure plates 807, and they are symmetrically distributed with each other. The air pump 801 is fixedly connected to the upper surface of the movable plate 7, and the vent pipe 802 is fixedly connected to the output end of the air pump 801. The vent pipe 802 has two flow outlets, and the flow outlets of the vent pipe 802 respectively lead into the two fixed sleeves 804.

[0027] The fixed plate 803 is fixedly connected to the side surface of the movable plate 7, the fixed sleeve 804 is fixedly connected to the side surface of the fixed plate 803, the sliding shaft 806 is slidably connected to the inner cylindrical surface of the fixed sleeve 804, and the matching surfaces of the sliding shaft 806 and the fixed sleeve 804 are provided with sealing rings, the pressure plate 807 is fixedly connected to the end face of the sliding shaft 806, the spring 805 is fixedly connected between the fixed plate 803 and the pressure plate 807, the spring 805 is ringed on the outside of the cylindrical surface of the fixed sleeve 804, and the spring 805 is always in a tensioned state.

[0028] The upper surface of the base plate 1 is fixedly connected to the servo motor 3 away from the workbench 12, the output end of the servo motor 3 is fixedly connected to the rotating shaft 4, the upper end surface of the rotating shaft 4 is fixedly connected to the first servo cylinder 5, and the output end of the first servo cylinder 5 is fixedly connected to the first piston rod 6.

[0029] Working principle: When in use, multiple tubular parts to be inspected are placed on the unloading ramp 10, and the lowest tubular part will roll down and be stuck in the V-groove. Then, the second servo cylinder 13 drives the push plate 15 to move, and pushes the tubular part stuck in the V-groove toward the direction of the laser detector 19. When the pushed tubular part is detected by the detection laser emitted by the laser detector 19, the laser detector 19 transmits this information to the controller 17. After receiving this information, the controller 17 determines the length of the tubular part according to the distance the second servo cylinder 13 drives the push plate 15 to move. If qualified, the controller 17 will drive the second servo cylinder 13 to drive the push plate 15 back to the initial position, and then drive the first servo cylinder 5 to drive the moving plate 7 to move until the tubular part stuck in the V-groove is close to the laser detector 1 9 until one end is between the two pressure plates 807, then the controller 17 controls the air pump 801 to inflate the fixed sleeve 804, drives the sliding shaft 806 and the pressure plate 807 to move, and clamps the tubular part. Then the controller 17 drives the first servo cylinder 5 to drive the movable plate 7 to return to the initial position, and then the controller 17 controls the servo motor 3 to drive the fixed clamping mechanism 8 to the top of the good product frame 18, and then turns off the air pump 801 through the controller 17. At this time, the pressure plate 807 will release the pressure on the tubular part, and the tubular part will fall into the good product frame 18; if it is unqualified, the controller 17 will drive the second servo cylinder 13 to drive the push plate 15 to continue moving forward until the unqualified tubular part is pushed into the defective frame 2 below, and then returns to the initial position, and repeats this process to test the remaining tubular parts.

Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention.
