Description

Technical Field

[0001] The utility model relates to the field of hardness detection, in particular to a PTFE pipe hardness detection device. Background Art

[0002] Pipes refer to materials used in pipeline systems for transporting fluids, gases or solids. They usually have certain flexibility, corrosion resistance and pressure resistance to meet the needs of different application scenarios. PTFE pipes are increasingly used in society because of their excellent chemical resistance, extremely low friction coefficient, excellent temperature resistance and good insulation performance. In the production process of PTFE pipes, in order to ensure that the strength of the finished product is qualified, it is often necessary to conduct strength testing on the pipes. During the testing process, the pipes need to be fixed, but because the side of the pipe is an arc surface, the traditional clamps have fewer contact points when clamping the pipes, which is prone to slipping.

[0003] After searching, Chinese patent announcement number: CN220271067U discloses a tube hardness testing device that prevents rolling, including a platform, a base fixedly installed at the bottom of the platform, a grinding device arranged on the platform, and the grinding device includes: a telescopic rod A, fixedly connected to the top of the platform; a rotating shaft, rotatably connected to the top of the telescopic rod A through a bearing; a grinding wheel, sleeved on the rotating shaft, and the inner wall of the grinding wheel is fixedly connected to the rotating shaft; a positioning hole, opened on the side of the grinding wheel. Through the hardness testing device, the tube between the presentation platform and the meniscus is fixed by using the telescopic rod B, and the position of the retractable hardness testing pen is moved by manually sliding the sliding plate, thereby solving the problem that the testing device cannot fix the tube well, resulting in uneven force on the tube when receiving the test, thereby achieving the function of testing different positions of the tube.

PTFE is a high-performance engineering plastic with special properties, with excellent chemical resistance, extremely low friction coefficient and good insulation performance, but the texture of the material is also brittle. When testing the hardness, it is easy to break due to excessive squeezing force. The upper surface of the machine 1 is provided with an adjustment component, the adjustment component can control the height of the clamping component, and the inside of the machine 1 is provided with a clamping component.

The rear surface of the fixed plate 31 is fixedly connected with a hollow tube 45, and a circular hole 401 is opened on the lower surface of the hollow tube 45. The aperture of the circular hole 401 is small, which can limit the flow rate of air. The inner wall of the hollow tube 45 is elastically connected with a rubber pad 44 through a compression spring 46.

[0033] Reference Figure 1 - Figure 3 The fixing plate 31 penetrates and is slidably connected to the inner wall of the front side of the machine 1, and the upper surface of the support rod 41 is fixedly connected to the lower surface of the fixing plate 31. When the fixing plate 31 moves, it will drive the support rod 41 to move synchronously.

[0034] Reference Figure 1 - Figure 3 One end of the compression spring 46 is fixedly connected to the front surface of the rubber pad 44, and the other end of the compression spring 46 is fixedly connected to the inner wall of the front side of the hollow tube 45. When the rubber pad 44 moves forward, it will squeeze the compression spring 46 to generate a reaction force. The piston of the rubber pad 44 is connected to the inner wall of the hollow tube 45. When the rubber pad 44 moves, it will squeeze the air inside the hollow tube 45. The front surface of the round rod 43 is fixedly connected to the rear surface of the rubber pad 44. When the round rod 43 moves, it will drive the rubber pad 44 to move synchronously. The round rod 43 penetrates and is slidably connected to the rear surface of the hollow tube 45.

[0035] Reference Figure 2 - Figure 4 The clamping assembly also includes an articulated rod 47, a positioning block 48 is hinged on the lower surface of the articulated rod 47, and the positioning block 48 drives the articulated rod 47 to rotate when it moves. The lower surface of the positioning block 48 is slidably connected with a clamping block 1 49, and a slide groove 1 is provided on the lower surface of the positioning block 48. The clamping block 1 49 slides on the inner wall of the slide groove 1. The lower surface of the clamping block 1 49 is slidably connected with a clamping block 2 411, and a slide groove 2 is provided on the lower surface of the clamping block 1 49. The clamping block 2 411 slides in the slide groove. The inner wall of the second clamp block 411, when the second clamp block 411 contacts the pipe, the second clamp block 411 and the first clamp block 49 will gradually fit with the outer wall of the pipe to clamp and fix the pipe. The first clamp block 49, the second clamp block 411 and the positioning block 48 are arranged in two groups, which are symmetrically distributed up and down. The adjustment component also includes a slide plate 32, and a threaded rod 33 is penetrated and rotatably connected to the upper surface of the machine 1. The upper surface of the threaded rod 33 is fixedly connected to a turntable 34, and the threaded rod 33 and the turntable 34 will rotate synchronously.

[0036] Reference Figure 3 The upper surface of the hinge rod 47 is hinged to the rear surface of the slider 42 , and when the hinge rod 47 rotates, it pushes the slider 42 to slide along the lower surface of the support rod 41 .

[0037] Reference Figure 2 - Figure 4 The rear surface of the slide plate 32 is fixedly connected to the front surface of the fixed plate 31, and the slide plate 32 and the fixed plate 31 will move synchronously. The slide plate 32 is slidably connected to the inner wall of the machine platform 1 and slides longitudinally. The threaded rod 33 passes through and is threadedly connected to the upper surface of the slide plate 32. When the threaded rod 33 is rotated, the slide plate 32 will move longitudinally. The threaded rod 33 is self-locking. When the threaded rod 33 stops rotating, the position of the slide plate 32 will be fixed.

[0038] Reference Figure 1 and Figure 5The protective component includes a baffle 51, and a through hole 502 is opened on the upper surface of the baffle 51. When the detector 2 moves downward to detect the hardness of the pipe, it will pass through the through hole 502. The baffle 51 will not cause any obstruction to the detector 2. A clamping block 52 is fixedly connected to the front surface of the baffle 51. The inner wall of the clamping block 52 is elastically connected to the limiting block 54 through a limiting spring 53. The clamping block 52 and the limiting block 54 can limit the baffle 51.

[0039] Reference Figure 1 and Figure 5 The baffle plate 51 is slidably connected to the inner wall of the machine table 1 and slides in the front-back direction. One end of the limit spring 53 is fixedly connected to the right surface of the limit block 54, and the other end of the limit spring 53 is fixedly connected to the inner wall on the right side of the block 52. When the limit block 54 moves to the right, it will retract into the inner wall of the block 52 and squeeze the limit spring 53 to generate a reaction force. The limit block 54 penetrates and is slidably connected to the left surface of the block 52. A card slot 501 is provided on the inner wall of the front side of the machine table 1. The card slot 501 fits with the block 52. The card slot 501 is provided in an L shape. The block 52 Inserted in the inner wall of the card slot 501, the limit block 54 is inserted in the inner wall of the card slot 501, and the limit block 54 will be inserted in the L-shaped corner of the card slot 501, so as to limit the baffle 51. A handle is fixedly connected to the upper surface of the baffle 51 for easy grasping. The front surface of the limit block 54 is set as a slope, and the rear surface of the limit block 54 is set as a slope. By squeezing the slope of the limit block 54, the limit block 54 will move to the right to release the limit, but squeezing the slope of the limit block 54 requires a certain amount of force, so the limit block 54 will not move without the influence of external force.

[0040] Working principle: first, place the pipe to be tested on top of the clamp block 2 411 located below, and then rotate the turntable 34 to drive the threaded rod 33 to rotate. The rotating threaded rod 33 will drive the slide plate 32, the fixed plate 31 and the clamping assembly to move downward. When the clamp block 2 411 located above contacts the pipe, extrusion will occur. The reaction force of the extrusion will cause the upper and lower groups of clamp blocks 2 411 and clamp block 1 49 to rotate. Clamp block 2 411 will fit against the outer wall of the pipe, increase the contact points with the pipe, and ensure stability during clamping. After clamping is completed, stop rotating the turntable 34, and the device will be stable due to the self-locking of the threaded rod 33.

[0041] In order to prevent the pipe from being damaged due to excessive force when clamping the pipe, during the clamping process, when the clamping reaches a certain force, the positioning block 48 will not continue to move downward, the hinged rod 47 will rotate to push the slider 42 to move forward and backward, and the slider 42 will drive the round rod 43 and the rubber pad 44 to move synchronously. The moving rubber pad 44 will squeeze the compression spring 46 to generate a reaction force, and will also squeeze the air inside the hollow tube 45 to be discharged from the circular hole 401. Since the aperture of the circular hole 401 is small, the speed of movement of the device can be limited, which can play a buffering role. Then move the baffle 51 forward, and plug the block 52 and the limit block 54 into the slot 501. During plugging, the inclined surface of the front surface of the limit block 54 will be squeezed, and the limit block 54 will move to the right to retract the block 52 to release the obstruction and squeeze the limit spring 53 to generate a reaction force. After the plugging is completed, the reaction force of the limit spring 53 will push the limit block 54 to move to the left and insert it into the slot 501 to limit the baffle 51.

[0042] Then start the detector 2 to detect the hardness of the pipe. During the detection, the detector 2 will pass through the through hole 502, and the baffle 51 can block the broken pipe to prevent accidental injury to the staff. After the detection is completed, the detector 2 is closed and the baffle 51 is moved backward. When moving backward, the inclined surface of the rear surface of the limit block 54 will be squeezed, and the limit block 54 will move to the right to retract the block 52 to release the block and squeeze the limit spring 53 to generate a reaction force. When the block 52 and the slot 501 are disengaged, the reaction force of the limit spring 53 will push the limit block 54 out, and then the turntable 34 is rotated in the opposite direction to drive the slide plate 32, the fixed plate 31 and the clamping assembly to move upward. When the clamp block 2 411 located above is separated from the pipe, the reaction force of the compression spring 46 will push the rubber pad 44, the round rod 43, the slider 42 and the hinged rod 47 to return to their initial state, and then the pipe is removed to complete the detection work.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
