Description

Technical Field

[0001] This utility model relates to the field of plastic-lined pipe processing technology, specifically to a device for plastic-lined pipes with a laser thickness measuring mechanism. Background Technology

[0002] Plastic-lined pipe fittings are components used as inner linings to connect adjacent pipes. They prevent liquid and gas leakage at the pipe joints and ensure the stability of the connection between adjacent pipes. The diameter of the fitting should be slightly smaller than that of the pipes to be connected, and it should fit tightly after being snapped in place. It is usually used with a suitable pipe.

[0003] Before plastic-lined pipe fittings leave the factory, their thickness, length, and diameter need to be tested. Only qualified products can be sold. Such thickness testing equipment can reflect the pipe wall thickness through laser refraction. However, due to the limited number of testing heads, multiple tests are required, making it difficult to improve the efficiency of a single thickness test.

[0004] Now, a novel device with a laser thickness measurement mechanism for plastic-lined pipe fittings is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a device for plastic-lined pipe fittings with a laser thickness measurement mechanism to solve the problem of long detection time mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for plastic-lined pipe fittings with a laser thickness measuring mechanism, comprising a base plate and a support frame. The front and rear ends of the right side of the top of the base plate are respectively fixed with the support frame, and the plastic-lined pipe fittings are horizontally placed between the top ends of the support frame. A motor is fixed at the center inside the base plate. A movable groove is provided on the left side inside the base plate, and a screw is installed between the two sides inside the movable groove. A threaded block is threaded to the outer side of the screw, and an L-shaped frame is fixed to the top of the threaded block. A laser detector is fixed to the left side of the L-shaped frame. A sliding groove is provided horizontally at the top and bottom of the L-shaped frame, and a vertical rod is movably connected in the sliding groove. A horizontal rod is welded to the right side of the vertical rod, and a laser detector head one is installed on the side of the horizontal rod. A laser detector head two is installed on the right side of the top and bottom of the L-shaped frame, respectively.

[0007] As a further technical solution of this utility model, the left side of the output end of the motor is fixedly connected to the screw, and the L-shaped frame moves left and right with the threaded block.

[0008] As a further technical solution of this utility model, a sleeve block is fixed to the front end of the vertical rod, and an insert plate is inserted and fixed inside the sleeve block. A bolt is threadedly connected between the insert plate and the sleeve block. An arc-shaped rod is fitted between the front ends of the vertical rod, and connecting plates are fixed to the bottom and top ends of the arc-shaped rod, respectively. Screw holes are provided inside the connecting plates and the insert plate, and bolts are threadedly connected to the screw holes.

[0009] As a further technical solution of this utility model, the vertical rod is symmetrically fixed at the top and bottom of the arc-shaped rod, and the insert moves vertically in the sleeve block.

[0010] As a further technical solution of this utility model, a vertical frame is fixed to the right side of the center of the substrate, and through grooves are respectively provided at the center of the front and rear ends of the vertical frame. A pull rod is movably connected in the through groove, and a clamping block is fixed to the inside of the pull rod. A sponge block is fixed to the surface of the clamping block, and a spring is fixed between the clamping block and the through groove. The clamping block is attached and fixed to the front and rear ends of the plastic-lined pipe.

[0011] As a further technical solution of this utility model, the pull rod slides back and forth along the inner wall of the through groove, and the pull rod is embedded in the spring but does not contact it.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the equipment for plastic-lined pipe fittings with laser thickness measurement mechanism not only realizes single multi-directional detection and linkage detection of the inside and outside of the pipe fitting, but also realizes rapid locking of the pipe fitting;

[0013] By installing a laser probe head one on the side of the crossbar and laser probe head two on the right side of the top and bottom of the L-shaped frame, the plastic-lined pipe fitting to be inspected is horizontally fixed in the vertical frame. The motor is started and the screw moves the threaded block horizontally along the movable groove, forcing the threaded block to guide the L-shaped frame above to slide to the right. The laser detector guides laser probe head one and laser probe head two to perform laser reflection thickness detection on the inner and outer surfaces of the plastic-lined pipe fitting. As the L-shaped frame moves, when the vertical bar contacts the left side of the plastic-lined pipe fitting, it will also guide the vertical bar to move along the slide groove, expanding the detection range of the equipment.

[0014] By attaching an arc-shaped rod between the front ends of the vertical rods, the insert is first inserted longitudinally into the sleeve block, and then bolt two is screwed in for reinforcement. The arc-shaped rod is then attached to the surface of the insert through the connecting pieces at the top and bottom. After aligning the screw holes, bolt one is screwed in for reinforcement, which can lock the moving track of the upper and lower vertical rods, so that the laser detection head at the top and bottom is always in the same vertical plane. Alternatively, the arc-shaped rod can be removed, and the vertical rod can be manually guided to slide to perform thickness detection at different positions of the plastic-lined pipe fitting.

[0015] A vertical frame is fixed to the right side of the center of the substrate. The right side of the plastic-lined tube overlaps the symmetrical support frame. When inserting the plastic-lined tube, the pull rod is pulled at both the front and rear ends to move the symmetrical clamping blocks outward along the through groove. After the plastic-lined tube enters the vertical frame, the pull rod is released. After the spring is extended, the clamping blocks can be reset and the plastic-lined tube is pressed tightly with a sponge block. In conjunction with the support frame, the plastic-lined tube is prevented from shaking during thickness testing. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4An embodiment of this utility model provides: a device for a plastic-lined pipe fitting with a laser thickness measuring mechanism, including a base plate 1 and a support frame 2. The front end and rear end of the right side of the top of the base plate 1 are respectively fixed to the support frame 2, and the plastic-lined pipe fitting 3 is placed horizontally between the top ends of the support frame 2. A motor 5 is fixed at the center inside the base plate 1. A movable groove 6 is provided on the left side inside the base plate 1, and a screw 7 is installed between the two sides inside the movable groove 6. A threaded block 8 is threadedly connected to the outside of the screw 7, and an L-shaped frame 10 is fixed at the top of the threaded block 8. A laser detector 9 is fixed on the left side of the L-shaped frame 10. A sliding groove 11 is provided horizontally at the top and bottom of the L-shaped frame 10, and a vertical rod 12 is movably connected in the sliding groove 11. A horizontal rod 13 is welded to the right side of the vertical rod 12, and a laser detector head 14 is installed on the side of the horizontal rod 13. A laser detector head 25 is installed on the right side of the top and bottom of the L-shaped frame 10.

[0023] The left side of the output end of motor 5 is fixedly connected to screw 7, and L-shaped bracket 10 moves left and right with threaded block 8;

[0024] Specifically, such as Figure 1 As shown, the plastic-lined pipe fitting 3 to be tested is horizontally fixed in the vertical frame 4. The motor 5 is started and the screw 7 moves the threaded block 8 horizontally along the movable groove 6, forcing the threaded block 8 to guide the upper L-shaped frame 10 to slide to the right. The laser detector 9 guides the laser detector head 14 and the laser detector head 15 to detect the thickness of the inner and outer surfaces of the plastic-lined pipe fitting 3. As the L-shaped frame 10 moves, when the vertical rod 12 contacts the left side of the plastic-lined pipe fitting 3, it will also guide the vertical rod 12 to move along the slide groove 11.

[0025] A sleeve block 18 is fixed to the front end of the vertical rod 12, and a insert plate 17 is inserted and fixed inside the sleeve block 18. A bolt 27 is threaded between the insert plate 17 and the sleeve block 18. An arc-shaped rod 21 is attached to the front end of the vertical rod 12, and a connecting plate 22 is fixed to the bottom and top of the arc-shaped rod 21 respectively. A screw hole 19 is provided inside the connecting plate 22 and the insert plate 17 respectively, and a bolt 20 is threaded in the screw hole 19. The vertical rod 12 is symmetrically fixed to the top and bottom of the arc-shaped rod 21. The insert plate 17 moves vertically in the sleeve block 18.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, first insert the insert 17 longitudinally into the sleeve 18, then screw in the second bolt 27 for reinforcement. Then attach the arc rod 21 to the surface of the insert 17 through the connecting pieces 22 at the top and bottom. After aligning the screw holes 19, screw in the first bolt 20 for reinforcement. This can lock the moving track of the upper and lower vertical rods 12, so that the laser detectors 14 at the top and bottom are always in the same vertical plane. Alternatively, the arc rod 21 can be removed to manually guide the vertical rod 12 to slide and detect.

[0027] A vertical frame 4 is fixed to the right side of the center of the substrate 1. A through groove 24 is provided at the center of the front and rear ends of the vertical frame 4. A pull rod 23 is movably connected in the through groove 24. A clamping block 16 is fixed to the inside of the pull rod 23. A sponge block 26 is fixed to the surface of the clamping block 16. A spring 25 is fixed between the clamping block 16 and the through groove 24. The clamping block 16 is attached to the front and rear ends of the plastic-lined tube 3. The pull rod 23 slides back and forth along the inner wall of the through groove 24. The pull rod 23 is embedded in the spring 25 but does not contact it.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the right side of the plastic-lined pipe 3 overlaps above the symmetrical support frame 2. When inserting the plastic-lined pipe 3, the pull rod 23 is pulled at both ends to move the symmetrical clamping block 16 outward along the through groove 24. After the plastic-lined pipe 3 enters the vertical frame 4, the pull rod 23 is released. After the spring 25 is extended, the clamping block 16 can be reset and the plastic-lined pipe 3 is tightly pressed by the sponge block 26.

[0029] Working Principle: In use, the right side of the plastic-lined pipe 3 is first overlapped above the symmetrical support frame 2. The pull rod 23 is pulled at both ends of the plastic-lined pipe 3, moving the symmetrical clamping blocks 16 outwards along the through groove 24. After the plastic-lined pipe 3 enters the vertical frame 4, the pull rod 23 is released. After the spring 25 extends, the clamping blocks 16 return to their original position, and the sponge block 26 tightly presses down on the plastic-lined pipe 3. Then, the insert 17 is longitudinally inserted into the sleeve 18, and bolt 27 is screwed in for reinforcement. The arc-shaped rod 21 is then attached to the surface of the insert 17 via connecting pieces 22 at both ends. After aligning the screw holes 19, bolt 20 is screwed in for reinforcement. The moving tracks of the two vertical rods 12 can be locked, so that the laser probes 14 at the top and bottom are always in the same vertical plane. The arc rod 21 can also be removed to manually guide the vertical rod 12 to slide and perform thickness detection on different positions of the plastic-lined pipe fitting 3. Finally, the motor 5 is started and the screw 7 moves the threaded block 8 horizontally along the movable groove 6, forcing the threaded block 8 to guide the L-shaped frame 10 above to slide to the right. The laser detector 9 guides the laser probes 14 and 15 to perform thickness detection on the inner and outer surfaces of the plastic-lined pipe fitting 3. As the L-shaped frame 10 moves, when the vertical rod 12 contacts the left side of the plastic-lined pipe fitting 3, it will also guide the vertical rod 12 to move along the slide groove 11.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
