Description

Technical Field

[0001] This application relates to the field of pipe measurement technology, and in particular to an automatic measuring device for beadwork pipes. Background Technology

[0002] Beads are primarily made of glass and plastic. The production process typically involves melting the raw materials (plastic and glass), followed by drawing, cutting, and beading. The drawing machine is the core equipment for this process. After the tubing is processed, it needs to be measured promptly to ensure its quality and performance meet relevant standards and requirements. Common methods for measuring tubing length include direct measurement using tools such as a tape measure or laser rangefinder, or calculating the straight-line distance between the starting and ending points and considering allowances.

[0003] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0004] Common pipe measuring devices only achieve the purpose of length measurement. However, when pipes are suspended at a height, they will sag due to gravity. Excessive sag may cause the pipe to come into contact with the ground or other objects, while insufficient sag may affect the stress distribution and lifespan of the pipe. Common devices do not have relevant auxiliary structures to help measure the sag caused by gravity per unit length of pipe. The measurement and evaluation dimensions are relatively single, which is not conducive to a comprehensive and thorough evaluation of the pipe's performance. Utility Model Content

Common devices do not have relevant auxiliary structures to help measure the sag caused by gravity per unit length of pipe.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses an automatic measuring device for beadwork processing tubing. (Refer to...) Figure 1 The automatic measuring device for beadwork tubes includes a worktable 1 and a support base 2, a servo motor 3, a bidirectional screw 4, a limit post 5, an adjusting plate 6, a detection unit 7, and a clamping assembly 8 mounted on the top of the worktable 1. The bottom of the support base 2 is fixedly connected to the surface of the worktable 1. The servo motor 3 is threadedly connected to one side of the support base 2. The inner side of the bidirectional screw 4 is fixedly connected to the motor shaft of the servo motor 3 through a coupling. The two sides of the limit post 5 are fixedly connected to the opposite side surfaces of the support base 2. The adjusting plate 6 is slidably sleeved on the outside of the limit post 5. The detection unit 7 is located on one side of the adjusting plate 6.

[0036] The support base 2 is used to connect the servo motor 3, which is used to drive the bidirectional screw 4 and flexibly adjust the distance between the two sets of adjustment plates 6. The limiting post 5 passes through the interior of the adjustment plate 6 to limit the movement path of the adjustment plate 6. The detection part 7 is used to measure the sag of the pipe in its natural state. The clamping assembly 8 is used to clamp the end of the pipe and to measure its length.

[0037] The detection unit 7 includes a fixed frame 71, a hydraulic cylinder 72, a guide rod 73, a slider 74, and an infrared emitter 75. The inner side of the fixed frame 71 is fixedly connected to the surface of the adjusting plate 6. The hydraulic cylinder 72 is threadedly connected to the inner bottom of the fixed frame 71. The bottom of the guide rod 73 is fixedly connected to the output end of the hydraulic cylinder 72. The slider 74 is slidably sleeved on the outside of the fixed frame 71. The surface of the infrared emitter 75 is threadedly connected to the outer side of the slider 74.

[0038] The adjustment plate 6 is electrically connected to the signal receiver box 9 on the side opposite to the infrared transmitter 75.

[0039] The clamping assembly 8 includes a threaded handle 81, a sliding abutment 82, a limiting frame 83, and a limiting groove 84. The surface of the threaded handle 81 is rotatably connected to the top center of the limiting frame 83. The center of the sliding abutment 82 is fixedly connected to the bottom of the threaded handle 81. The bottom of the limiting frame 83 is fixedly connected to the top of the adjusting plate 6. The limiting groove 84 is located on the inner side of the limiting frame 83.

[0040] The outer side of the fixing frame 71 is provided with a groove 10 that matches the size of the slider 74.

[0041] The inside of the adjusting plate 6 is provided with threaded grooves 11 and through holes 12 that are adapted to the dimensions of the bidirectional screw 4 and the limiting post 5.

[0042] A laser rangefinder 13 is also installed on the top of the mounting bracket 71.

[0043] The inner side of the adjusting plate 6 is also provided with a mounting groove 14 that matches the size of the fixing frame 71.

[0044] The signal receiver box 9 includes a power supply circuit, a control circuit, an MCU, and a signal transceiver device, all of which are existing technologies.

[0045] The usage process of the automatic measuring device for beadwork tubing in this embodiment is roughly as follows:

[0046] By rotating the threaded handle 81, the limiting groove 84 inside the limiting frame 83 limits the sliding plate 82 at its bottom, causing it to move up and down within the limiting frame 83, thus clamping the pipe. The pipe is then stretched to the specified length required for installation between the two sets of adjusting plates 6. This process is monitored by the laser rangefinder 13. Next, the hydraulic cylinder 72 inside the fixing frame 71 is activated. The output end of the hydraulic cylinder 72 lifts the guide rod 73 and moves the slider 74 in the slotted direction of the slide groove 10, allowing the infrared emitter 75 on the outside of the slider 74 to move up and down repeatedly. The signal receiving box 9 can receive infrared light to provide real-time feedback on the sag of the pipe. By repeatedly tightening and loosening the pipe through the clamping component 8, the sag can be reduced or increased. After adjustment, the pipe can be cut to complete the processing and adjustment of the pipe. Since the limiting post 5 is fixedly connected to the surface of the support base 2, it can hinder the rotation of the adjusting plate 6. With the cooperation of the threaded groove 11 of the adjusting plate 6 and the threaded surface of the bidirectional screw 4, the adjusting plate 6 can move along the through hole 12 opened inside it on the surface of the limiting post 5, thereby completing the stretching of the pipe. The distance between the two sets of adjusting plates 6 is monitored in real time by the laser rangefinder 13 on the top of the fixing frame 71.

[0047] The beneficial technical effects of the automatic measuring device for beadwork tubing in this application embodiment are roughly as follows:

[0048] This device uses a servo motor 3 to adjust the linear spacing of the adjustment plate 6. Based on the specified length of the pipe to be installed on the adjustment plate 6 after stretching or contracting, the sliding abutment 82 clamps the pipe to ensure it reaches a natural hanging state. The laser rangefinder 13 and signal receiver 9 are both located directly below the outermost limiting frame 83, making the reading of the laser rangefinder 13 the length of the pipe, which is convenient to operate. Furthermore, the receiver built into the signal receiver 9 can receive infrared light. When the lower signal receiver 9 does not receive infrared light, it indicates that the pipe sag is too high, and the pipe quality is deemed unqualified.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
