[0044] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0045] like Figures 1 to 6As shown, a bottom groove measuring mechanism for an automatic hydraulic pipe detection device according to this solution includes: a fixed base 2, on which a positioning element 3 is provided, the positioning element 3 being used to position the hydraulic pipe to be detected; a diameter measuring component 4, which is disposed below the fixed base 2, the diameter measuring component 4 having two first measuring rods 5 passing through the fixed base 2 and movably abutting against the bottom groove 1 of the hydraulic pipe, the first measuring rods 5 being used to measure the diameter of the bottom groove 1; and a depth measuring component 6, which is disposed below the fixed base 2 and to the side of the diameter measuring component 4, the depth measuring component 6 having a second measuring rod 7 passing through the fixed base 2 and movably abutting against the hydraulic pipe, the second measuring rod 7 being used to measure the depth of the bottom groove 1.

[0046] During operation, the hydraulic pipe to be tested is placed on the positioning element 3, which is then inserted into the hydraulic pipe. The bottom groove 1 to be tested faces the fixed seat 2. After the hydraulic pipe is positioned, the diameter measuring component 4 drives the two first measuring rods 5 to abut against the inner or outer ring of the bottom groove 1. Before the two first measuring rods 5 move, the diameter measuring component 4 records the distance between the two measuring rods. After the two measuring rods abut against the inner or outer ring of the bottom groove 1, the distance the two measuring rods move relative to each other is recorded. By calculating the sum or difference between the two distances, the diameters of the inner and outer rings of the bottom groove 1 can be obtained respectively. In this way, the diameter of the bottom groove 1 can be automatically measured. During the measurement process, the depth measuring component 6 drives the second measuring rod 7 to touch the top wall of the bottom groove 1 and the lower end face of the hydraulic pipe. By measuring the distance the second measuring rod 7 moves from touching the lower end face of the hydraulic pipe to touching the top wall of the bottom groove 1, the depth of the bottom groove 1 can be obtained. In this way, the depth of the bottom groove 1 can be automatically measured. In this solution, the diameter measuring component 4 and the depth measuring component 6 measure the distance the first measuring rod 5 and the second measuring rod 7 move, respectively, to calculate the diameter of the inner and outer rings of the bottom groove 1 and the depth of the bottom groove 1. This reduces the measurement time of the hydraulic pipe bottom groove 1 and facilitates the inspection of a large number of hydraulic pipes.

[0047] Furthermore, the diameter measuring component 4 includes: a fixed frame 8, with a fixed base 2 connected to the upper end of the fixed frame 8; a first driving member 9 connected to the fixed frame 8; two first movable seats 10 movably connected to the fixed frame 8, each of the first movable seats 10 being provided with a first measuring rod 5, the first driving member 9 being used to drive the two first movable seats 10 to move closer or further apart from each other; and a first measuring member 11 having a first main body 12 connected to one of the first movable seats 10 and a first movable part 13 connected to the other first movable seat 10, the first main body 12 being used to record the distance the first movable part 13 moves relative to the first main body 12.

[0048] During operation, the first driving member 9 drives the two first moving seats 10 to move, thereby causing the two first measuring rods 5 to move closer or further apart. This allows the two first measuring rods 5 to abut against the inner or outer ring wall of the bottom groove 1, completing the measurement of the inner and outer ring diameters of the bottom groove 1. Simultaneously, while the first driving member 9 moves the two first moving seats 10, one of the first moving seats 10 presses against the first movable part 13 of the first measuring member 11, causing the first movable part 13 to move a certain distance relative to the first main body 12. By measuring the sum or difference between the distance moved by the first movable part 13 and the initial distance between the two first measuring rods 5, the diameter of the outer or inner ring of the bottom groove 1 is determined. Preferably, a sensor is provided inside the first main body 12 to record the distance the first movable part 13 moves relative to the first main body 12.

[0049] Furthermore, the diameter measuring component 4 also includes: a drive wheel 14 connected to the output end of the first drive member 9; a pull rope 15, which is tied to the drive wheel 14 at its middle position, and the pull rope 15 is contracted or relaxed when the first drive member 9 drives the drive wheel 14 to rotate; and a first elastic member 16, which is connected to each first moving seat 10, and the end of the pull rope 15 is connected to the first elastic member 16.

[0050] During operation, when the first driving member 9 drives the drive wheel 14 to rotate, causing the two first measuring rods 5 to move closer together, the drive wheel 14 causes the pull rope 15 to contract on the drive wheel 14. When the pull rope 15 contracts, it causes the first elastic member 16 to be in a compressed state. When the first driving member 9 drives the drive wheel 14 to reverse and cause the two first measuring rods 5 to move away from each other, the first elastic member 16 returns to an extended state and causes the pull rope 15 to reset. Preferably, the pull rope 15 can be a nylon rope or a steel wire rope.

[0051] Furthermore, the first elastic element 16 includes: a connecting sleeve 17, a first movable seat 10 extending downward in a vertical direction to form a fixing part 18, one end of the connecting sleeve 17 being threadedly connected to the fixing part 18, and the other end of the connecting sleeve 17 being provided with a first limiting part 19; a sleeve 20, one end of which is inserted into the side of the connecting sleeve 17 having the first limiting part 19, and the side of the sleeve 20 away from the connecting sleeve 17 being provided with a second limiting part 21; a spring 22, which is sleeved on the outer wall of the sleeve 20, and the two ends of the spring 22 abutting against the first limiting part 19 and the second limiting part 21 respectively; a third limiting part 23, which abuts against the second limiting part 21, and the end of the pull rope 15 passing through the connecting sleeve 17 and the sleeve 20 in sequence and being connected to the third limiting part 23.

[0052] The fixing part 18 and the first movable seat 10 can be integrally formed or separately set. The threaded connection between the connecting sleeve 17 and the fixing part 18 can be achieved by setting an external thread on the outer wall of the connecting sleeve 17 and setting a threaded hole on the fixing part 18, or by setting an external thread on the connecting sleeve 17 and setting a through hole on the fixing part 18, and fixing the connecting sleeve 17 to the fixing part 18 with a nut after the connecting sleeve 17 passes through the through hole. When the first driving member 9 drives the pull rope 15 to retract by driving the drive wheel 14 to rotate, the third limiting part 23 at the end of the pull rope 15 moves towards the drive wheel 14. During the movement of the third limiting part 23, it pushes the second limiting part 21 to move towards the drive wheel 14 and compresses the spring 22. When the first driving member 9 drives the pull rope 15 to relax by driving the drive wheel 14 to reverse, the spring 22 returns to the extended state and pushes the second limiting part 21 to move away from the drive wheel 14. When the second limiting part 21 moves, it pushes the third limiting part 23 to move and drives the pull rope 15 to reset.

[0053] Furthermore, the fixed frame 8 is provided with a second movable seat 24 and a second driving member 25 arranged in the vertical direction. The second movable seat 24 is connected to the output end of the second driving member 25, and the first driving member 9 is connected to the second movable seat 24. The second driving member 25 is used to drive the second movable seat 24 to move in the vertical direction.

[0054] After the hydraulic pipe is placed on the positioning component 3, the second driving component 25 drives the second moving seat 24 to move upward in the vertical direction, thereby causing the first measuring rod 5 to move closer to the bottom groove 1. Then, the first driving component 9 drives the two first moving seats 10 to move, so that the two first measuring rods 5 move closer to the inner and outer rings of the bottom groove 1.

[0055] Furthermore, the depth measurement component 6 includes: a third drive member 26, which is vertically connected to one of the first movable seats 10; a third movable seat 27, which is connected to the output end of the third drive member 26, the third drive member 26 being used to drive the third movable seat 27 to move in the vertical direction, a second measuring rod 7 being connected to the third movable seat 27; and a second measuring member 28, the second measuring member 28 having a second main body portion 29 connected to the first movable seat 10 and a second movable portion 30 connected to the third movable seat 27, the second main body portion 29 being used to record the distance the second movable portion 30 moves relative to the second main body portion 29.

[0056] After the first driving member 9 drives the two first measuring rods 5 to measure the diameter of the outer ring of the bottom groove 1, the third driving member 26 drives the third moving seat 27 to move vertically, so that the second measuring rod 7 touches the lower end face of the hydraulic pipe. At this time, the second measuring member 28 records the vertical position of the second measuring rod 7 by recording the distance the second moving part 30 moves relative to the second main body part 29. Then, the first driving member 9 drives the two first moving seats 10 to move closer to each other, and drives the two first measuring rods 5 to move closer to each other to measure the inner ring diameter of the bottom groove 1. When the first moving seat 10 moves, it drives the second measuring rod 7 to move directly below the bottom groove 1. At this time, the third driving member 26 drives the third moving seat 27 to move, and drives the second measuring rod 7 to move towards the top wall of the bottom groove 1 until the second measuring rod 7 touches the top wall of the bottom groove 1. Then, the second measuring member 28 calculates the thickness of the bottom groove 1 by recording the difference between the values ​​obtained by the two touches of the second measuring rod 7.

[0057] Furthermore, this solution also includes a pressing component 31, which is used to press the hydraulic tube onto the positioning member 3 after the hydraulic tube is placed on the positioning member 3.

[0058] Furthermore, the pressing assembly 31 includes: a fourth driving member 32, which is horizontally disposed on the fixed base 2; two fourth moving seats 33 connected to the output ends of the fourth driving member 32, the fourth driving member 32 being used to drive the two fourth moving seats 33 to move closer or further apart from each other, each of the two fourth moving seats 33 having a contoured part adapted to the shape of the hydraulic pipe on its opposite side, the contoured part being movable against the outer wall of the hydraulic pipe; a floating block 34, with a floating block 34 connected to each of the fourth moving seats 33; and two fifth driving members 35, which are disposed on both sides of the fixed base 2, each of the fourth driving members 32 having a pushing block at its output end, the pushing block being movable against the floating block 34.

[0059] After the positioning element 3 is inserted into the hydraulic tube, the fourth drive element 32 drives the two first moving seats 10 to move closer to each other, so that the contour part provided on the fourth moving seat 33 is fitted onto the outside of the hydraulic tube. Then, the two fifth drive elements 35 drive the push block to rotate above the floating block 34 and press it on the floating block 34, so that the floating block 34 moves vertically downward on the fourth moving seat 33 until the lower end of the floating block 34 presses against the hydraulic tube, pressing the hydraulic tube against the positioning element 3 to prevent the hydraulic tube from moving during the measurement process and affecting the measurement accuracy of the hydraulic tube. After the hydraulic tube measurement is completed, the two fifth drive elements 35 drive the push block to rotate away from the positioning element 3 and then rise. At this time, the floating block 34 is no longer pressed by the push block and is no longer in contact with the hydraulic tube. Finally, the fourth drive element 32 drives the two fourth moving seats 33 to move away from each other, so that the fourth moving seat 33 is away from the outer wall of the hydraulic tube, so that the hydraulic tube can be removed from the positioning element 3.

[0060] Furthermore, the pressing assembly 31 also includes: a guide post 36, which passes through the floating block 34 and is connected to the fourth movable seat 33; a connecting post 37, one end of which passes through the floating block 34 and is threadedly connected to the fourth movable seat 33; and a second elastic member 38, which is sleeved on the outer wall of the connecting post 37, with both ends of the second elastic member 38 abutting against the fourth movable seat 33 and the floating block 34 respectively.

[0061] When the pushing block pushes the floating block 34 to move downwards in the vertical direction, the floating block 34 compresses the second elastic element 38. During the process of the pushing block separating from the floating block 34, the second elastic element 38 returns to its extended state, pushing the floating block 34 to reset. The guide post 36 is used to ensure that the movement direction of the floating block is always in the vertical direction. Preferably, the second elastic element 38 can be a spring 22 or a rubber product.

[0062] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0064] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly.
