Description

TECHNICAL FIELD

[0002] Incoming inspection refers to quality confirmation and checking of raw materials, parts or products purchased from suppliers, that is, when the supplier sends raw materials or parts, the quality is inspected through sampling, and finally it is judged whether the products are accepted or rejected. However, for some high-quality parts, full inspection of the same batch of products is required during incoming inspection. For example, a hydraulic pipe assembly shown in FIG. 1 and FIG. 2 includes a hydraulic pipe 1 and a cap 2. Before the next assembly process, the cap 2 needs to be separated from the hydraulic pipe 1, and then the wall thickness of the upper mounting hole 4 of the hydraulic pipe 1 is detected to check whether the wall thickness of the mounting hole 4 is uniform, and whether the inner and outer diameters of the bottom groove 3 and the depth of the bottom groove 3 meet the requirements of the drawing. The traditional operation mode is to separate the cap 2 from the hydraulic pipe 1 by manual operation, and then detect the sizes by using a caliper.

Embodiment

[0086] The following are specific embodiments of the present application and further describe the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

[0087] As shown in FIGS. 3-18, the hydraulic pipe automatic detection device comprises a machine table 5, a rotating disc 6, a cap removal mechanism 7, a wall thickness measuring mechanism 8, a bottom groove measuring mechanism 10, a first placement area 92, a second placement area 94, and a plurality of material taking parts 11.

[0088] Specifically, the rotating disc 6 is arranged on the machine table 5 and used for placing the hydraulic pipe 1 to be detected; the cap removing mechanism 7 is arranged on the machine table 5 and located at the side of the rotating disc 6, and is used for separating the cap 2 on the hydraulic pipe 1; the wall thickness measuring mechanism 8 is arranged on the machine table 5 and located at the side of the cap removing mechanism 7, and the wall thickness measuring mechanism 8 movably has two wall thickness measuring rods 9 arranged thereon, the two wall thickness measuring rods 9 are respectively abutted against the inner wall and the outer wall of the hydraulic pipe 1 and can rotate around the axis direction of the mounting hole 4 of the hydraulic pipe 1, so as to measure the wall thickness of the hydraulic pipe 1; the bottom groove measuring mechanism 10 is arranged on the machine table 5 and located at the side of the cap removing mechanism 7 away from the wall thickness measuring mechanism 8, and is used for measuring the diameter and the depth of the bottom groove 3 of the hydraulic pipe 1; the material taking member 11 is arranged on the machine table 5 and used for taking the hydraulic pipe 1 from the rotating disc 6 and placing the hydraulic pipe 1 on the cap removing mechanism 7, the wall thickness measuring mechanism 8 and the bottom groove measuring mechanism 10 in sequence; a first placing area 92 is arranged at the side of the machine table 5, and the first placing area 92 has three conveying belts 93 arranged thereon, and each of the conveying belts 93 is used for placing the unqualified hydraulic pipe 1; a second placing area 94 is arranged at the side of the machine table 5, and the second placing area 94 is used for placing the qualified hydraulic pipe 1.

[0089] The material taking member 11 is preferably a mechanical hand. The mechanical hand is an automatic operating device which can imitate some action functions of human hands and arms, and is used for grasping, carrying objects or operating tools according to fixed programs. The mechanical hand has the advantages of both human hands and mechanical devices in structure and performance, and can complete various expected operations through programming. The material taking member 11 can be one, two or more.

[0090] The rotating disc 6 can be circular or quadrangular as shown in the figure. Preferably, the machine table 5 is provided with a motor for driving the rotating disc 6 to rotate, and the machine table 5 is further provided with a sensor for sensing whether there is a hydraulic pipe assembly on the rotating disc 6. The sensor is located below the rotating disc 6 and is electrically connected with the motor. The hydraulic pipe 1 can be a straight pipe or a bent pipe. When the hydraulic pipe 1 is a bent pipe as shown in the figure, the rotating disc 6 is further provided with a support block for abutting against the bent part of the hydraulic pipe 1. The support block can be adjusted in height on the rotating disc 6 to adapt to hydraulic pipes 1 of different sizes.

[0091] During operation, the hydraulic pipe assembly to be detected is placed on the rotating disc 6, and the motor drives the rotating disc 6 to rotate to a position where the mechanical hand can grasp the hydraulic pipe assembly. After the sensor senses that the part of the rotating disc 6 close to the mechanical hand is free of the hydraulic pipe assembly, the sensor transmits a sensing signal to the motor to drive the rotating disc 6 to rotate, so that the side of the rotating disc 6 close to the mechanical hand is always provided with the hydraulic pipe assembly to be detected.

[0092] After the mechanical hand grabs the hydraulic pipe assembly on the rotating disc 6, it is first grabbed to the cap removing mechanism 7, the hydraulic pipe 1 is separated from the cap 2 through the cooperation between the mechanical hand and the cap removing mechanism 7, then the mechanical hand grabs the hydraulic pipe 1 to the wall thickness measuring mechanism 8, so that the end of the hydraulic pipe 1 with the mounting hole 4 is placed downward on the wall thickness measuring mechanism 8, at this time, one of the wall thickness measuring rods 9 is inserted into the mounting hole 4, and the other wall thickness measuring rod 9 is outside the mounting hole 4, then the wall thickness measuring mechanism 8 drives the two wall thickness measuring rods 9 to approach each other, so that the two wall thickness measuring rods 9 abut on the inner wall and the outer wall of the hydraulic pipe 1 respectively, after the two wall thickness measuring rods 9 abut on the inner wall and the outer wall of the hydraulic pipe 1, the wall thickness measuring mechanism 8 drives the two wall thickness measuring rods 9 to rotate around the axis direction of the mounting hole 4, in the process of rotation of the two wall thickness measuring rods 9, since the two wall thickness measuring rods 9 always abut on the inner wall and the outer wall of the hydraulic pipe 1, when the wall thickness of the hydraulic pipe 1 is inconsistent, the relative distance between the two wall thickness measuring rods 9 changes in the process of rotation, that is, when the wall thickness of the hydraulic pipe 1 becomes thick, the two wall thickness measuring rods 9 move away from each other, when the wall thickness of the hydraulic pipe 1 becomes thin, the two wall thickness measuring rods 9 move close to each other, at this time, the distance of the mutual movement of the two wall thickness measuring rods 9 is recorded, that is, the size range of the change of the wall thickness of the hydraulic pipe 1 is obtained, the size range is compared with the size tolerance on the drawing, that is, whether the change of the wall thickness of the hydraulic pipe 1 is within the range required by the drawing is obtained, finally, according to the detection result, the mechanical hand picks out the unqualified product in the incoming material, and completes the wall thickness detection operation of the hydraulic pipe 1.

[0093] After the wall thickness detection of the hydraulic pipe 1 is completed, the mechanical hand grabs the hydraulic pipe 1 with unqualified wall thickness to the first placement area 92, three conveying belts 93 arranged on the first placement area 92 are respectively used for placing the hydraulic pipe 1 with unqualified wall thickness, the hydraulic pipe 1 with unqualified diameter of the bottom groove 3 and the hydraulic pipe 1 with unqualified depth of the bottom groove 3, the qualified hydraulic pipe 1 is transferred to the bottom groove measuring mechanism 10, the bottom groove measuring mechanism 10 starts to detect the diameter and the depth of the bottom groove 3, after the detection is completed, the mechanical hand places the unqualified hydraulic pipe 1 in the first placement area 92, and distinguishes according to the unqualified types, the qualified hydraulic pipe 1 is re-grabbed to the cap removing mechanism 7 to assemble the cap 2, finally, the mechanical hand grabs the assembled hydraulic pipe assembly to the second placement area 94, and completes the detection of the hydraulic pipe assembly. In the scheme, through the cooperation of the rotating disc 6, the cap removing mechanism 7, the wall thickness measuring mechanism 8, the bottom groove measuring mechanism 10 and the material taking part 11 on the machine 5, the automatic cap removing, detection, assembly and classification of the hydraulic pipe assembly are completed, the detection work of the large batch of hydraulic pipe assemblies is accelerated, and the detection time of the hydraulic pipe assembly is reduced.

[0094] Further, the cap removing mechanism 7 comprises a bottom plate 12, a suction table 13 for sucking the cap 2 on the hydraulic pipe 1 movably arranged on the bottom plate 12 in the vertical direction, a first driving member 14 arranged on the bottom plate 12 in the length direction of the bottom plate 12, an output end of the first driving member 14 being provided with a connecting member 15, a first sliding way 16 arranged on the bottom plate 12 and located at one side of the output shaft of the first driving member 14, a first sliding block 17 slidingly arranged on the first sliding way 16, a pressing plate 18 threadedly connected to the first sliding block 17, the connecting member 15 being connected to the side of the pressing plate 18, the first driving member 14 being used to drive the pressing plate 18 to move towards or away from the suction table 13, a second driving member 19 arranged on one side of the bottom plate 12 in the length direction, an output end of the second driving member 19 being provided with a first driving wheel 20, a first driven wheel 21 rotatably arranged on the other side of the bottom plate 12 in the length direction, the first driven wheel 21 being connected with the first driving wheel 20 through a first belt 22, a receiving table 23 arranged on the bottom plate 12 and arranged in parallel with the first belt 22, the receiving table 23 being located at the side of the suction table 13 away from the pressing plate 18, and the upper end surface of the receiving table 23 being flush with the suction table 13, a moving table 24 slidingly connected to the bottom plate 12 and fixed to the first belt 22, and a third driving member 25 arranged on the moving table 24 in the vertical direction, an output end of the third driving member 25 being connected with a pushing member 26.

[0095] After the mechanical hand grasps the hydraulic pipe assembly on the rotating disc 6, the mechanical hand places the hydraulic pipe assembly on the suction table 13 and presses the cap 2 on the hydraulic pipe 1 against the suction table 13, at this time the suction table 13 can be tightly sucked on the lower end surface of the cap 2, the suction table 13 moves downward in the vertical direction under the pushing of the hydraulic pipe 1, so that the cap 2 on the hydraulic pipe 1 is in a position that can be pressed by the pressing plate 18, after the mechanical hand presses the hydraulic pipe assembly against the suction table 13, the first driving member 14 drives the first sliding block 17 to move on the first sliding way 16 through the driving connecting member 15, when the first sliding block 17 moves, the pressing plate 18 arranged on the first sliding block 17 presses the upper end of the cap 2, thereby completing the pressing operation of the pressing plate 18 on the cap 2, after the pressing plate 18 is pressed above the cap 2, the mechanical hand drives the hydraulic pipe 1 to rotate towards the horizontal plane where the cap 2 is located, so that the hydraulic pipe 1 is separated from the cap 2, thereby automatically completing the automatic separation of the hydraulic pipe 1 from the cap 2.

[0096] After the hydraulic pipe 1 is separated from the cap 2, the manipulator takes the hydraulic pipe 1 to the wall thickness measuring mechanism 8 for next operation, and the suction table 13 is reset after the manipulator takes away the hydraulic pipe 1. In the initial state, the pushing piece 26 is on the side of the bottom plate 12 close to the pressing plate 18 and above the pressing plate 18, after the hydraulic pipe 1 is separated from the cap 2, the second driving piece 19 drives the first driving wheel 20 to rotate to drive the first belt 22 to rotate, when the first belt 22 rotates, the moving table 24 moves on the bottom plate 12 to drive the pushing piece 26 to move towards the suction table 13, after the pushing piece 26 moves to the side of the suction table 13, the third driving piece 25 drives the pushing piece 26 to move downward in the vertical direction, then the suction table 13 stops adsorbing the cap 2, the second driving piece 19 drives the moving table 24 to move along the length direction of the bottom plate 12 again by driving the first driving wheel 20 to rotate, so that the pushing piece 26 pushes the cap 2 on the suction table 13 to the receiving table 23, so that the manipulator can place the next hydraulic pipe 1 needing to be uncapped on the suction table 13, thereby realizing the continuity of production of the automatic uncapping mechanism 7 of the present scheme.

[0098] In work, the gas pipe joint 30 is connected to the gas source, a negative pressure is formed in the cavity 27 through the gas source, finally, the cap 2 is adsorbed on the suction table 13 through the gas hole 29 on the fixing disc 28, thereby realizing the adsorption function of the suction table 13 to the cap 2.

[0099] Further, the end of the pressing plate 18 close to the suction table 13 is provided with a semicircular position avoiding part 31, the side of the receiving table 23 away from the suction table 13 is provided with a groove 32, the side of the abutting block 33 away from the receiving table 23 is provided with a first profiling part 34.

[0100] The semicircular position avoiding part 31 is used for avoiding the side wall of the hydraulic pipe 1, so that the pressing plate 18 can better press on the upper end of the cap 2, after the pushing piece 26 pushes the cap 2 to the groove 32 and clamps the cap 2 between the pushing piece 26 and the abutting block 33, the manipulator takes the qualified hydraulic pipe 1 to the upper side of the cap 2 and reinserts the hydraulic pipe 1 into the cap 2, thereby completing the final assembly of the hydraulic pipe assembly, and the first profiling part 34 is arranged to prevent the cap 2 from easily falling out of the groove 32 when the manipulator assembles the hydraulic pipe 1 and the cap 2.

[0102] When the manipulator presses the hydraulic pipe 1 on the suction table 13, the suction table 13 moves downward along the vertical direction and compresses the spring. After the taking part 11 separates the hydraulic pipe 1 from the cap 2 and the pressing plate 18 cancels the pressing of the cap 2, the spring slowly extends and drives the suction table 13 to reset. The fixed column is used for guiding the movement of the taking table. The limiting table and the countersunk hole are used for connecting the suction table 13 and the fixed column. The spring is used for resetting the suction table 13. The suction of the suction table 13 to the cap 2 is mainly to prevent the cap 2 from being ejected from the suction table 13 when the spring drives the suction table 13 to reset.

[0103] Further, the wall thickness measuring mechanism 8 comprises: a fixed plate 35; two first movable plates 36 movably arranged on the fixed plate 35, two second sliding grooves 37 are oppositely arranged on the fixed plate 35, a plurality of second sliding blocks 38 are arranged at the bottom of each first movable plate 36, the second sliding block 38 is movably arranged on the second sliding groove 37, and a clamping block 39 is arranged on each first movable plate 36; a fourth driving member 40 is fixed on one of the first movable plates 36, the output end of the fourth driving member 40 is connected to the other first movable plate 36, and the fourth driving member 40 is used to drive the two first movable plates 36 to move close to or away from each other; a rack 41 is arranged on the opposite side of each second sliding groove 37, the rack 41 is connected to the second sliding block 38, a gear 42 is arranged on the fixed plate 35, the gear 42 is between the two racks 41 and is engaged with the two racks 41; a rotating table 43 is rotatably arranged on the fixed plate 35 and below the clamping block 39; two second movable plates 44 are arranged on the rotating table 43, a third sliding groove 45 is arranged on the rotating table 43, a third sliding block 46 is arranged on each second movable plate 44, the third sliding block 46 is slidably arranged on the third sliding groove 45, and a wall thickness measuring rod 9 is arranged on each second movable plate 44; a fifth driving member 47 is connected to one of the second movable plates 44, and the output end of the fifth driving member 47 is connected to the other second movable plate 44, and the fifth driving member 47 is used to drive the two second movable plates 44 to move close to or away from each other; a first measuring member 48 has a first main body 49 connected to one of the second movable plates 44 and a first moving part 50 connected to the other second movable plate 44, and when the two second movable plates 44 move close to or away from each other, the first main body 49 measures the distance between the two second movable plates 44 by recording the relative movement distance of the first moving part 50.

[0104] After the hydraulic pipe 1 and the cap 2 are separated, the manipulator will grab the hydraulic pipe 1 between the two clamping blocks 39, and insert one of the wall thickness measuring rods 9 into the mounting hole 4 of the hydraulic pipe 1, the fourth driving member 40 drives the two clamping blocks 39 to move close to or away from each other by driving the two first movable plates 36 to move close to or away from each other, so as to clamp or release the hydraulic pipe 1, and the second slide 37 and the second slide block 38 are arranged to realize the sliding connection between the first movable plate 36 and the fixed plate 35.

[0105] As shown in FIG. 15, when the fourth driving member 40 drives one of the first movable plates 36 to move, it drives the right rack 41 to move, when the right rack 41 moves, it drives the left rack 41 to move in the opposite direction through the gear 42 between the two racks 41, when the left rack 41 moves in the opposite direction of the right rack 41, it drives the other first movable plate 36 (not shown in the figure) to move in the opposite direction, so as to realize the moving away from or moving close to each other of the two first movable plates 36.

[0106] After the clamp block 39 fixes the hydraulic pipe 1, the fifth driving part 47 drives the two second movable plates 44 to move close to each other, so that the two wall thickness measuring rods 9 are respectively abutted on the inner side wall and the outer side wall of the hydraulic pipe 1. At this time, one of the second movable plates 44 is pressed on the first moving part 50 of the first measuring part 48, so that the first moving part 50 moves a certain distance relative to the first main part 49 of the first measuring part 48. Then, the rotating table 43 rotates relative to the fixed plate 35. When the rotating table 43 rotates, the two wall thickness measuring rods 9 are driven to rotate by the two second movable plates 44. Since the two wall thickness measuring rods 9 are always abutted on the inner wall and the outer wall of the hydraulic pipe 1, when the wall thickness of the hydraulic pipe 1 is uniform, the two wall thickness measuring rods 9 will not relatively displace. When the wall thickness of the hydraulic pipe 1 changes, the two wall thickness measuring rods 9 will relatively displace, and the two second movable plates 44 will also relatively displace. At this time, the first moving part 50 of the first measuring part 48 will relatively displace with the first main part 49 of the first measuring part 48 under the drive of the second movable plate 44. That is, when the wall thickness of the mounting hole 4 of the hydraulic pipe 1 becomes thick, the two wall thickness measuring rods 9 will move away from each other. When the wall thickness of the mounting hole 4 of the hydraulic pipe 1 becomes thin, the two wall thickness measuring rods 9 will move close to each other. At this time, the distance that the two wall thickness measuring rods 9 move is recorded, so that the size range of the wall thickness change of the mounting hole 4 of the hydraulic pipe 1 is obtained. The size range is compared with the size tolerance on the drawing, so that whether the wall thickness change of the mounting hole 4 of the hydraulic pipe 1 is within the range required by the drawing is obtained. Finally, according to the detection result, unqualified products in the incoming material are picked out, and the full inspection operation of the mounting hole 4 of the hydraulic pipe 1 is completed. According to the present scheme, the fifth driving part 47 drives the two wall thickness measuring rods 9 to move close to or away from each other. After the two wall thickness measuring rods 9 rotate one circle around the wall thickness of the mounting hole 4 of the hydraulic pipe 1, whether the distance that the two wall thickness measuring rods 9 relatively move is within the size tolerance on the drawing is judged, whether the mounting hole 4 of the hydraulic pipe 1 is qualified is judged, and the wall thickness detection of the mounting hole 4 of the hydraulic pipe 1 is automatically completed. The detection efficiency of the mounting hole 4 of the hydraulic pipe 1 is improved, and the full inspection operation of the mounting hole 4 of the hydraulic pipe 1 is adapted to a large quantity. Preferably, the first main part 49 is internally provided with a sensor for recording how much distance the first moving part 50 moves relative to the first main part 49.

[0110] The pressing sheet 59 is used to fix the two bearings 57 on the connecting column 56, and when the rotating table 43 drives the two wall thickness measuring rods 9 to rotate, the measuring sheet 58 abuts against the inner wall and the outer wall of the hydraulic pipe 1 while also rotating around the axis of the column 55, changing the sliding friction between the measuring sheet 58 and the hydraulic pipe 1 into rolling friction, thereby preventing the inner wall and the outer wall of the hydraulic pipe 1 from being scratched, and the two bearings 57 are provided to realize the rotation of the measuring sheet 58.

[0112] After the wall thickness measurement of the hydraulic pipe 1 installation hole 4 is completed, the manipulator picks up the qualified hydraulic pipe 1 to the fixed seat 61, and inserts the positioning piece 95 into the inside of the hydraulic pipe 1. Then the tenth driving part 76 drives the two fourth moving seats 77 to approach each other, so that the second profiling part 78 arranged on the fourth moving seat 77 is sleeved on the outside of the hydraulic pipe 1, and then the two eleventh driving parts 80 drive the push block 81 to rotate to the upper side of the floating block 79 and press on the floating block 79, so that the floating block 79 moves downward along the vertical direction on the fourth moving seat 77 until the lower end of the floating block 79 is pressed tightly on the hydraulic pipe 1, and the hydraulic pipe 1 is pressed tightly on the positioning piece 95, so as to prevent the hydraulic pipe 1 from moving during the measurement and affecting the measurement accuracy of the hydraulic pipe 1. After the measurement of the hydraulic pipe 1 is completed, the two eleventh driving parts 80 drive the push block 81 to rotate away from the positioning piece 95 and then rise, at this time the floating block 79 is separated from the hydraulic pipe 1 without the pressing of the push block 81, and finally the tenth driving part 76 drives the two fourth moving seats 77 to move away from each other, so that the fourth moving seat 77 moves away from the outside wall of the hydraulic pipe 1, and the hydraulic pipe 1 can be taken out of the positioning piece 95.
