Description

Technical Field

[0001] The invention relates to the technical field of hydraulic brake joint detection, in particular to an automatic detection device for hydraulic brake joint threads. Background Art

[0002] The hydraulic brake joint is a hydraulic system that connects different hydraulic components to form a closed loop. It is an accessory that plays a connecting role. The application range of hydraulic brake joints is wide, and there are many types of hydraulic brake joints, generally including external thread joints and internal thread joints. When producing internal thread joints, it is necessary to detect the internal threads of the internal thread joints. The traditional detection method generally sets an external thread screw-in part that matches the internal thread joint at the detection station, rotates the external thread screw-in part to the internal thread of the internal thread joint, and collects data during the screw-in process to detect whether the internal thread joint is qualified.

[0003] When inspecting existing internal threaded joints, the external threaded insert is generally directly rotated into the internal thread of the internal threaded joint for inspection. However, due to the internal threaded joint being processed, there may be some foreign matter inside the internal threaded joint, such as metal burrs adsorbed inside the internal threaded joint. During inspection, these foreign matter will affect the inspection results and reduce the accuracy of the inspection. In addition, it is inconvenient to flip the internal threaded joint during inspection, which makes it inconvenient to inspect both ends of the internal threaded joint. When flipping, the internal threaded joint is often flipped manually by employees, which increases the workload and has the problem of low inspection efficiency. Summary of the invention

[0016] The present invention has the following beneficial effects:

[0017] 1. In the automatic detection device for thread of hydraulic brake joint, the joint workpiece is first clamped and fixed by the annular positioning seat, and then conveyed by the annular conveyor line. During the conveying process, the first nozzle is used to blow air into the interior of the joint workpiece to remove foreign matter. At the same time, the convex column slides in the annular guide groove, which can drive the rotating shaft to rotate, so that the flip seat can be flipped, and the flip seat drives the joint workpiece to flip. The second nozzle is used to blow air into the interior of the joint workpiece again to remove foreign matter. Before the two ends of the joint workpiece are inspected, foreign matter is removed by blowing air into the interior of the joint workpiece twice, which increases the removal effect of foreign matter inside the joint workpiece. Moreover, the flipping of the joint workpiece can be automatically completed during the conveying process, avoiding the problem of manually flipping the joint workpiece by employees, increasing the workload, and having the problem of low detection efficiency.

[0018] 2. In the automatic detection device for threads of hydraulic brake joints, when the turning seat turns over, the first slide bar is driven to slide in the arc-shaped slide groove, and the first slide bar drives the gear ring to rotate through the second gear plate, so that the clamped and fixed joint workpiece can be rotated, and at the same time, the lifting rod drives the resistance slider to slide in the lifting groove, which can drive the lifting rod to lift and lower. When the lifting rod is lifted and lowered, the clamped and fixed joint workpiece can be driven to shake left and right, so that the joint workpiece can rotate and shake while being blown, which can increase the contact range during blowing, facilitate a larger contact surface for blowing, and thus more conveniently remove foreign matter inside the joint workpiece;

[0019] 3. In the automatic detection device for threads of hydraulic brake joints, when the lifting rod is raised, the first convex plate and the second convex plate contact each other, driving the extrusion plate to squeeze the airbag. When the airbag is squeezed, gas is rushed into the annular air cavity through the air guide tube to lift the annular sealing plate, and the clamping seat is lifted through the adjusting rod, so that the clamped joint workpiece can extend forward. When the lifting rod is lowered, the joint workpiece shrinks backward and resets, so that the clamped joint workpiece can be extended and retracted forward and backward while rotating and shaking, so that the joint workpiece is closer to the air source, so that the effect of blowing to remove foreign matter is better.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] For example, see Figure 1-Figure 11 , a hydraulic brake joint thread automatic detection device, comprising a feeding base plate 2 and a first detection station 3 and a second detection station 4 arranged on a circular conveyor line 1, a connecting plate 5 that moves synchronously with the circular conveyor line 1 is fixed on the feeding base plate 2, a side plate 6 is fixed on the feeding base plate 2, a rotating shaft 7 is rotatably connected to the side plate 6, a flip seat 8 is fixed at the end of the rotating shaft 7, a first rotating groove 9 is arranged in the side plate 6, a gear 10 is rotatably arranged in the first rotating groove 9, the gear 10 is key-connected to the rotating shaft 7, a first tooth plate 11 is meshed on the gear 10, a first slideway 12 for the first tooth plate 11 to slide is opened on the side plate 6, an annular guide plate 13 is also arranged on the circular conveyor line 1, an annular guide plate 13 is opened on the annular guide plate 13, a boss 15 is fixed at the end of the first tooth plate 11, and the boss 15 is slidably arranged in the annular guide groove 14;

[0034] An annular support seat 16 is fixed on the flip seat 8, and an annular positioning seat 17 for clamping the joint workpiece 42 is fixed on the annular support seat 16. The joint workpiece 42 is arranged through the flip seat 8. A first nozzle 18 is fixed on the first inspection station 3, and a second nozzle 19 is fixed on the second inspection station 4. The first nozzle 18 and the second nozzle 19 blow air into the joint workpiece 42 to remove impurities.

[0035] The annular guide groove 14 includes a horizontal top portion 141, a first descending portion 142, a horizontal bottom portion 143 and a first ascending portion 144 which are sequentially connected and arranged;

[0036] A first positioning clamping plate 20 is fixed inside one side of the annular positioning seat 17, and an adjusting bolt 21 is threadedly connected to the other side of the annular positioning seat 17. The other end of the adjusting bolt 21 is rotatably provided with a second positioning clamping plate 22 that cooperates with the first positioning clamping plate 20 to fix the joint workpiece 42;

[0037] In the present technical solution, the joint workpiece 42 is a two-end internal thread structure. When testing, the joint workpiece 42 is first inserted into the annular positioning seat 17 and the flip seat 8 (such as Figure 2As shown in the figure), by rotating the adjusting bolt 21, the adjusting bolt 21 drives the second positioning clamping plate 22 to move toward the first positioning clamping plate 20, so that the first positioning clamping plate 20 and the second positioning clamping plate 22 cooperate to clamp and fix the joint workpiece 42, and then the joint workpiece 42 is transported through the ring conveyor line 1;

[0038] Before the joint workpiece 42 is transported to the first inspection station 3, the feeding bottom plate 2 drives the boss 15 to slide on the horizontal top 141. When the boss 15 slides along the first descending portion 142, the boss 15 pulls the first tooth plate 11 to move downward. The downward movement of the first tooth plate 11 drives the gear 10 to rotate. The rotation of the gear 10 drives the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the flip seat 8 to flip. During the process of flipping the flip seat 8 by 30°-60°, the first nozzle 18 blows air into the inside of the joint workpiece 42 to blow out foreign matter inside the joint workpiece 42 from the other end, so as to facilitate the removal of foreign matter inside the joint workpiece 42. When the boss 15 slides to the lowest part of the first descending portion 142, the flip seat 8 flips 180°, and then the boss 15 slides along the horizontal bottom 143. When passing the first inspection station 3, the annular conveyor line 1 stops moving. The first inspection station 3 screws the detection piece into the internal thread of the joint workpiece 42 to check one side of the joint workpiece 42. The first inspection station 3 is reset after the inspection, and the annular conveyor line 1 continues to convey. When the boss 15 slides along the first rising portion 144, the gear 10 and the rotating shaft 7 are driven to reverse, and the rotating shaft 7 drives the flip seat 8 to reversely flip. When the flip seat 8 rotates 30°-60° in the opposite direction, the second nozzle 19 can blow air into the inside of the joint workpiece 42 again, and the foreign matter that may be generated inside the joint workpiece 42 during the inspection of one end of the joint workpiece 42 is blown out from the other end of the joint workpiece 42. When the boss 15 slides to the horizontal top 141, the first tooth plate 11 is reset, and the flip seat 8 is reversely rotated 180° to flip. When passing the second inspection station 4, the annular conveyor line 1 stops, and the second inspection station 4 screws the inspection piece into the internal thread of the joint workpiece 42 to inspect the other end of the joint workpiece 42. After the inspection, the second inspection station 4 is reset, and the annular conveyor line 1 continues to convey, completing the automatic inspection of the thread of the joint workpiece 42.

[0039] The annular conveyor line 1, the first inspection station 3 and the second inspection station 4 are all prior art and will not be described in this technical solution. The first nozzle 18 and the second nozzle 19 are both connected to an air pump to complete the air supply.

[0040] In the second embodiment, when blowing air to remove foreign matter from the joint workpiece 42, if the relative position state of the joint workpiece 42 and the first nozzle 18 and the second nozzle 19 remains unchanged, the gas will only be blown to one side of the joint workpiece 42, so that the force range of the blowing is limited, thereby reducing the blowing effect, further affecting the effect of blowing out foreign matter. In view of this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 11 The side plate 6 is provided with an arc-shaped slide groove 23, a first slide bar 24 is slidably arranged in the arc-shaped slide groove 23, a second tooth plate 25 is fixed to the end of the first slide bar 24, a second rotating groove 26 is provided inside the flip seat 8, a gear ring 27 is rotatably arranged in the second rotating groove 26, and the second tooth plate 25 is meshed with the gear 10;

[0041] A spherical groove 28 is provided in the support seat, a hollow ball 29 is rotatably arranged in the spherical groove 28, a joint workpiece 42 passes through the hollow ball 29, a connecting rod 30 is fixed on the hollow ball 29, and the connecting rod 30 is fixedly connected to the lower surface of the annular positioning seat 17;

[0042] The arc-shaped slide groove 23 includes a first stabilizing portion 231, a first rotating portion 232, a second rotating portion 233 and a second stabilizing portion 234 which are sequentially connected and arranged;

[0043] A receiving groove 31 is provided in the flip seat 8, a lifting rod 32 is inserted in the receiving groove 31, the lifting rod 32 passes through the gear ring 27, and is rotatably connected to the bottom of the annular positioning seat 17, a second slideway 33 for the lifting rod 32 to slide is provided on the flip seat 8, a resisting slider 34 is fixed to the bottom of the lifting rod 32, and a lifting groove 35 for the resisting slider 34 to rise and fall is provided in the receiving groove 31;

[0044] The lifting slot 35 includes a second rising portion 351 and a second descending portion 352 which are connected in sequence;

[0045] In the present technical solution, when the flip seat 8 is flipped, the first slide bar 24 is driven to slide in the arc-shaped slide groove 23 by the second tooth plate 25. During the process of flipping the flip seat 8 by 30°-60° (i.e., during the process of blowing air by the first nozzle 18), the first slide bar 24 will slide from the first stable portion 231 to the second stable portion 234. When the first slide bar 24 slides from the bottom of the first rotating portion 232 to the top of the first rotating portion 232 (i.e., the bottom of the second rotating portion 233), the first slide bar 24 drives the second tooth plate 25 to move rightward (i.e., Figure 6As shown in the figure, the second tooth plate 25 moves to the right to drive the tooth ring 27 to rotate, the rotation of the tooth ring 27 drives the lifting rod 32 to rotate, the rotation of the lifting rod 32 drives the annular positioning seat 17 to rotate, the rotation of the annular positioning seat 17 drives the hollow ball 29 and the clamped joint workpiece 42 to rotate, and the hollow ball 29 is used to support the annular positioning seat 17 to increase the stability of the annular positioning seat 17; when the first slide bar 24 slides from the bottom of the second rotating part 233 to the top of the second rotating part 233 (that is, the bottom of the second stable part 234), the first slide bar 24 drives the second tooth plate 25 to move left, the second tooth plate 25 moves to the left to drive the tooth ring 27 to rotate in the opposite direction, and the tooth ring 27 drives the lifting rod 32 to rotate in the opposite direction, so that the clamped joint workpiece 42 rotates in the opposite direction. Through the above process, in the process of flipping the flip seat 8 by 30°-60°, the joint workpiece 42 can be rotated forward and reversely, so that the first nozzle 18 can better blow air inside the joint workpiece 42, so as to better remove foreign matter;

[0046] When the lifting rod 32 rotates, the lifting rod 32 drives the resistance slider 34 to slide in the lifting groove 35. When the resistance slider 34 slides on the second rising portion 351 of the lifting groove 35, the lifting rod 32 can be driven to move upward. The lifting rod 32 moves upward to apply an upward thrust to the annular positioning seat 17. Due to the action of the hollow ball 29, the annular positioning seat 17 drives the hollow ball 29 to roll in the spherical groove 28 to achieve rightward deflection. When the resistance slider 34 slides on the second descending portion 352 of the lifting groove 35, the lifting rod 32 can be driven to move downward. The lifting rod 32 moves downward to apply a downward pulling force to the annular positioning seat 17, so that the annular positioning seat 17 drives the hollow ball 29 to roll in the spherical groove 28 to achieve leftward deflection, so that the annular positioning seat 17 can swing left and right while the annular positioning seat 17 rotates, so that the joint workpiece 42 can be rotated and shaken when being blown, so that foreign matter inside the joint workpiece 42 can be removed more conveniently.

[0047] When the flip seat 8 is flipped back to 30°-60° (that is, during the blowing process of the second nozzle 19), the first slide bar 24 will slide from the second stable portion 234 to the first stable portion 231 for reset. During the reset, the action of the joint workpiece 42 is the same as the above principle, that is, the second tooth plate 25 will drive the gear ring 27 to rotate, and the rotation of the gear ring 27 drives the joint workpiece 42 to rotate through the lifting rod 32 and the annular positioning seat 17. While the joint workpiece 42 is rotating, the lifting rod 32 is used to drive the resistance slider 34 to slide in the lifting groove 35, so that the lifting rod 32 is lifted and lowered. The lifting of the lifting rod 32 drives the annular positioning seat 17 to swing left and right, so that the joint workpiece 42 can rotate and shake while being blown. Through the above process, during the reverse flipping of the flip seat 8 by 30°-60°, the second nozzle 19 can better blow air into the inside of the joint workpiece 42, so as to better remove foreign matter.

[0048] Embodiment 3: Since the distance between the joint workpiece 42 and the first nozzle 18 and the second nozzle 19 remains almost unchanged when the joint workpiece 42 is blown to remove foreign matter, no matter how the joint workpiece 42 swings and rotates, the port of the joint workpiece 42 cannot be moved toward the first nozzle 18 and the second nozzle 19 during the blowing process. When the first nozzle 18 and the second nozzle 19 are far away from the joint workpiece 42, the effect of blowing to remove foreign matter will also be relatively poor. In view of this problem, this embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 11 The annular positioning seat 17 includes a clamping seat 171 and a fixing seat 172 arranged up and down. An annular air cavity 173 is provided in the fixing seat 172. An annular sealing sheet 174 is slidably provided in the annular air cavity 173. An adjusting rod 175 is fixed on the annular sealing sheet 174. The end of the adjusting rod 175 is fixedly connected to the clamping seat 171. A spring 176 is sleeved on the adjusting rod 175. The two ends of the spring 176 are respectively fixed on the inner wall of the annular sealing sheet 174 and the fixing seat 172. One side of the annular air cavity 173 is connected to an air supply component.

[0049] The air supply assembly includes an air bag 36 disposed in the receiving groove 31, a squeezing plate 37 is fixed to the bottom of the air bag 36, a first convex plate 38 is fixed to the squeezing plate 37, a second convex plate 39 that abuts against the first convex plate 38 is fixed to the bottom of the lifting rod 32, an air guide tube 40 is connected to the air bag 36, the air guide tube 40 passes through the flip seat 8, and is connected to the annular air cavity 173, and a third slideway 41 for the air guide tube 40 to slide is provided on the flip seat 8;

[0050] In the present technical solution, when the resisting slider 34 slides in the second rising portion 351 of the lifting groove 35, it can drive the lifting rod 32 to move upward, and the lifting rod 32 drives the second convex plate 39 to move upward. The second convex plate 39 resists the first convex plate 38, so that the first convex plate 38 drives the extrusion plate 37 to move upward, and squeezes the airbag 36. The gas enters the annular air cavity 173 through the air guide tube 40. After the annular air cavity 173 is inflated, the annular sealing plate 174 is pushed upward, so that the annular sealing plate 174 drives the adjusting rod 175 to move upward, and compresses the spring 176, so that the spring 176 accumulates force, and the adjusting rod 175 moves upward to drive the clamping seat 171 to move upward. The first positioning clamping plate 20 and the second positioning clamping plate 22 are both arranged on the inner side of the clamping seat 171, so that the clamped workpiece moves upward, so that the end of the joint workpiece 42 can be blown toward the first nozzle 18 or the second nozzle 18 when the air is blown. The nozzle 19 moves, so that the joint workpiece 42 is closer to the first nozzle 18 or the second nozzle 19, which is convenient for increasing the effect of removing foreign matter; when the resistance slider 34 slides in the second descending portion 352 of the lifting groove 35, it can drive the lifting rod 32 to move downward, and the lifting plate drives the second convex plate 39 to move downward. The first convex plate 38 loses the resistance of the second convex plate 39, and the extrusion plate 37 will move downward. At the same time, the spring 176 unloads the force, and the gas inside the annular air cavity 173 is again rushed into the airbag 36 to reset the airbag 36. The spring 176 unloads the force and drives the adjusting rod 175 to reset, thereby resetting the clamping seat 171; through the above process, the clamped and fixed joint workpiece 42 can be extended and retracted forward and backward while rotating and shaking, thereby adjusting the distance between it and the first nozzle 18 or the second nozzle 19, so that the effect of blowing to remove foreign matter is better.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
