Description

Technical Field

[0001] The present invention relates to the technical field of camshaft detection, and in particular to a camshaft detection system. Background Art

[0002] In today's society, although the country is vigorously advocating the use of new energy vehicles, traditional fuel vehicles still have irreplaceable advantages in terms of endurance, service life, and power supply. At this stage, fuel vehicles still have greater advantages than electric vehicles. The most important component of a traditional car is the engine, and the camshaft is one of the key components of the engine.

[0003] Since the quality, safety and life of the camshaft have a vital impact on the performance of the engine, camshaft quality inspection has always been a concern for camshaft manufacturers. Camshaft surface defects are one of the important factors affecting the quality of the camshaft. Traditional defect detection is mostly post-production sampling, but post-production sampling is prone to missed inspections and increased defect rates. Building a detection system on the production line to achieve non-destructive, fast, and high-accuracy production online detection is one of the good ways to solve this problem.

[0004] At present, most of the inspection systems on the production line use industrial cameras to take pictures of each surface of the camshaft to be inspected, and compare them with the pictures of the standard camshaft to determine whether the camshaft to be inspected has defects. In the prior art, there are currently two main methods that mainly install industrial cameras on the four sides of the camshaft to take pictures; but there are problems such as high cost and inconvenience in camshaft transportation. After the improvement, the camshaft is fixed by a clamp, and the clamp is driven to rotate by a motor, so that the four sides of the camshaft correspond to the industrial camera one by one, and take pictures, which can effectively reduce costs, but it is necessary to take pictures of the four sides of the camshaft one by one, and the inspection efficiency is low. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a camshaft detection system to solve the problem in the prior art that when detecting surface defects of the camshaft, it is necessary to take photos of the four surfaces of the camshaft one by one, resulting in low detection efficiency.

[0006] The present invention solves the above technical problems by the following technical means:

By setting the above-mentioned structure, the detection device of the present invention can take pictures of four camshafts at four positions at the same time, and as the plate chain conveyor is transported, when the camshaft moves to the next position, the driving member drives the transmission member to move, the transmission member drives the transmission head to rotate, and the transmission head drives the camshaft to rotate through the positioning sleeve, so that the camshaft rotates, so that all surfaces of the camshaft can be exposed to the camera, so that the detection device can take pictures, effectively improving the detection efficiency.

[0008] Furthermore, the transmission member is a rack, a slide groove is provided on the support member, the rack is slidably arranged in the slide groove, a gear is provided at the end of the transmission head, the rack meshes with the gear, and the transmission member and the transmission head are connected by the above structure. The driving member is a driving plate, and the driving plate is fixedly mounted on the guard plate. The driving plate includes a first step surface, a second step surface and a third step surface. A first arc surface is provided between the first step surface and the guard plate, between the second step surface and the first step surface, and between the third step surface and the second step surface. A second arc surface is provided between the third step surface and the guard plate. By providing the above structure, when the rack passes through the driving plate, the driving plate pushes the rack to move up, thereby realizing the rotation of the camshaft, and the camshaft rotates 90° each time. After three rotations, the camera can collect image information of each surface of the camshaft.

[0009] Furthermore, the support member is arranged on a first protrusion below the transmission head, a rod body is fixedly mounted on the first protrusion, a second protrusion is arranged on one side of the bottom of the rack, a through hole is provided on the second protrusion, the rod body is inserted into the through hole, a spring is arranged on the rod body, one end of the spring is connected to the first protrusion, and the other end is connected to the second protrusion. By setting the above structure, the spring remains in a compressed state, and the spring pushes the bottom of the rack to connect with the upper surface of the guard plate, so that the transmission head can maintain the initial angle. After the drive plate pushes the rack to move upward, the spring will be further compressed. After the rack passes the drive plate, the spring can restore the deformation, drive the rack to return to the initial position, and at the same time drive the transmission head to restore the initial angle, so that the camshaft restores the initial angle.

[0010] Furthermore, the support member is provided with a notch, the end of the positioning sleeve is clamped in the notch, the end of the positioning sleeve is provided with a limiting groove, the end of the transmission head is provided with a first limiting strip, and the first limiting strip is clamped in the limiting groove.

Both ends of the bottom of the feeding box are provided with discharge assemblies, and the discharge assemblies are used to output the camshafts in the storage cavity one by one.

[0012] Further, the discharging assembly includes a first limit block, a second limit block and a connecting block, the loading box is provided with a first slide groove at the first limit block, the loading box is provided with a second slide groove at the second limit block, the first limit block is slidably arranged in the first slide groove, the second limit block is slidably arranged in the second slide groove, one end of the connecting block is hinged to the first limit block, and the other end is hinged to the second limit block, both ends of the bottom of the loading box are provided with hinge seats, and the middle part of the connecting block is rotatably connected to the hinge seat through a torsion spring. By setting the above structure, the first limit block is inserted into the loading box, and the second limit block can be driven to withdraw from the loading box through the connecting block. In the above process, the first limit block separates the camshaft in the loading box except the lowermost end, and the second limit block is disengaged from the limit of the lowermost camshaft after withdrawing, and the lowermost camshaft can fall out of the loading box. After the first limit block is loosened, the torsion spring causes the connecting block to rotate automatically, so that the second limit block is inserted into the loading box again, the first limit block withdraws from the loading box, disengages from the limit on the upper camshaft, and the upper camshaft falls onto the second limit block for the next loading.

[0013] Furthermore, a mounting hole is provided on the support member, and the transmission head is rotatably set in the mounting hole. A fixing groove is provided on the top of the support member, and a limiting plate is fixedly installed in the fixing groove.

[0014] Furthermore, a stop block is provided at the bottom of the second limit block, and an arc block is provided on the limit plate for driving the stop block to move away from the loading box. When the support passes through the discharge assembly, the arc block squeezes the stop block to move away from the loading box, thereby causing the second limit block to withdraw from the loading box. At the same time, the first limit block is driven to be inserted into the loading box through the connecting block.

[0015] Furthermore, the detection device includes a detection bracket and a camera, wherein the detection bracket is fixedly mounted on the guard plate, the camera is fixedly mounted on the detection bracket, and a processor is disposed on the detection bracket, and the processor is electrically connected to the camera.

The first slide rail assembly has the same structure as the second slide rail assembly. The first slide rail assembly and the second slide rail assembly are sequentially arranged under the plate body. The first slide rail assembly includes two slide rails with the same structure. The ends of the slide rails are hinged with a movable plate through a torsion spring. By setting the above structure, when the camshaft moves to the bottom of the unloading device, the processor controls the cylinder to work, and the cylinder drives the hook to move upward, and the camshaft is lifted by the hook body, so that the camshaft enters the first slide rail assembly or the second slide rail assembly to complete the unloading.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention connects the positioning sleeve with the transmission head. When the positioning sleeve rotates, the transmission head can drive the camshaft to rotate. And by setting a rack and a drive plate, when the plate chain conveyor drives the conveying plate to move, and the conveying plate passes the drive plate, the drive plate drives the rack to move, and the rack drives the transmission head to rotate through the gear, and the transmission head drives the camshaft to rotate through the positioning sleeve, so that all surfaces of the camshaft can be exposed to the camera, so that the camera can take pictures of the camshaft surface. And the camera can take pictures of four camshafts at a time, which can effectively improve the detection efficiency.

[0019] 2. Through the first step surface, second step surface, third step surface, first arc surface and second arc surface set on the driving plate, the camshaft rotates at an angle of 90° each time, that is, the front end of the driving plate is the 0° shooting point, the first step surface is the 90° shooting point, the second step surface is the 180° shooting point, and the third step surface is the 270° shooting point. After the camshaft rotates three times, the camera can collect images of the four surfaces of the camshaft for detection to ensure the detection effect.

[0020] 3. By setting a discharge assembly at the bottom of the loading box, when the support member passes through the discharge assembly, the arc block squeezes the stop block to move away from the loading box, so that the second limit block withdraws from the loading box. At the same time, the first limit block is driven by the connecting block to insert into the loading box, so that the lowermost cam shaft falls onto the support member. After the support member passes through the discharge assembly, the discharge assembly automatically resets and limits the cam shaft in the discharge box again to prevent the discharge box from falling out.

[0021] 4. By setting the processor and the cylinder, the processor detects whether the camshaft has defects through image comparison. When the camshaft is located in the unloading device, the processor controls the cylinder to work, and the cylinder drives the hook to move upward, and lifts the camshaft through the hook body, and lifts the standard camshaft into the second slide rail assembly, or lifts the defective camshaft into the first slide rail assembly.

The camshaft 2 is placed on the conveying plates 511 so that when the plate chain conveyor 51 is working, the camshaft 2 is driven to move toward the detection device 53.

[0034] In this embodiment, a transmission head 42 is rotatably arranged on the support member 4, a limiting groove 211 is opened at the end of the positioning sleeve 21, and a first limiting strip 421 is arranged at the end of the transmission head 42. The first limiting strip 421 is clamped in the limiting groove 211. By setting the first limiting strip 421 and the limiting groove 211, the positioning sleeve 21 and the transmission head 42 are clamped.

[0036] A driving member is provided at the position of the guard plate 512 corresponding to the detection device 53, and the driving member is a driving plate 6. The driving plate 6 is fixedly mounted on the guard plate 512, and the driving plate 6 includes a first step surface 61, a second step surface 62 and a third step surface 63. A first arc surface 64 is provided between the first step surface 61 and the guard plate 512, between the second step surface 62 and the first step surface 61, and between the third step surface 63 and the second step surface. A second arc surface 65 is provided between the third step surface 63 and the guard plate 512. When the rack 43 passes through the driving plate 6, the driving plate 6 pushes the rack 43 to move upward, thereby realizing the rotation of the camshaft 2. In this embodiment, the camera 72 captures images of the four camshafts 2 below at one time. The camshaft 2 rotates 90° each time, the front end of the drive plate 6 is the 0° shooting point, the first step surface 61 is the 90° shooting point, the second step surface 62 is the 180° shooting point, and the third step surface 63 is the 270° shooting point.

[0037] The support member 4 is arranged on the first protrusion 45 below the transmission head 42, and a rod body 451 is fixedly mounted on the first protrusion 45. A second protrusion 431 is arranged on one side of the bottom of the rack 43, and a through hole is provided on the second protrusion 431. The rod body 451 is inserted into the through hole. A spring 452 is arranged on the rod body 451, and one end of the spring 452 is connected to the first protrusion 45, and the other end is connected to the second protrusion 431. In this embodiment, the spring 452 is kept in a compressed state, and the spring 452 pushes the bottom of the rack 43 to connect with the upper surface of the guard plate 512, so that the transmission head 42 can be kept at the initial angle, so that the starting angle of each camshaft 2 is the same, which is convenient for detection. And after the driving plate 6 pushes the rack 43 to move upward, the spring 452 will be further compressed. After the rack 43 passes through the driving plate 6, the spring 452 can restore the deformation, drive the rack 43 to return to the initial position, and drive the transmission head 42 to restore the initial angle, so that the camshaft 2 restores the initial angle.

[0038] The feeding device 52 includes a feeding box 1. In this embodiment, the feeding box 1 is fixedly mounted on the guard plate 512 through a mounting plate 15. A storage chamber 11 is provided in the feeding box 1. The storage chamber 11 runs through the feeding box 1. The storage chamber 11 is used to store the camshaft 2. The camshaft 2 can be placed in the storage chamber 11 manually or automatically. In this embodiment, the camshaft 2 is automatically placed in the storage chamber 11 by a mechanical arm to be detected. Second limiting strips 111 are provided on both sides of the storage chamber 11. The limiting groove 211 of the positioning sleeve 21 is slidably clamped on the second limiting strip 111. By setting the second limiting strip 111, the initial angle of the camshaft 2 can be limited to ensure that the positioning sleeve 21 can carry the camshaft 2 to smoothly enter the notch 41.

[0039] Both ends of the bottom of the loading box 1 are provided with a discharging assembly, and the discharging assembly is used to output the camshafts 2 in the storage chamber 11 one by one. The discharging assembly includes a first limit block 31, a second limit block 32 and a connecting block 33. The loading box 1 is provided with a first slide groove 4412 at the first limit block 31, and the loading box 1 is provided with a second slide groove 4413 at the second limit block 32.

Both ends of the bottom of the loading box 1 are provided with hinge seats 14, and the middle part of the connecting block 33 is rotatably connected to the hinge seat 14 through a torsion spring. By providing the connecting block 33, when the second limit block 32 is moved, the first limit block 31 can be driven to move through the connecting block 33, so that only one camshaft 2 is dropped out at a time.

[0040] A mounting hole 46 is provided on the support member 4, and the transmission head 42 is rotatably set in the mounting hole 46. A fixing groove 47 is provided on the top of the support member 4, and a limiting plate 471 is fixedly installed in the fixing groove 47. A limiting ring groove 423 is provided on the transmission head 42, and the limiting plate 471 is clamped in the limiting ring groove 423. Through the above structure, the transmission head 42 can be rotatably installed on the sub-support member 4.

[0041] The second limit block 32 is provided with a stopper 321 at the bottom, and the limit plate 471 is provided with an arc block 472 for driving the stopper 321 to move away from the loading box 1. When the support member 4 passes through the discharge assembly, the arc block 472 squeezes the stopper 321 to move away from the loading box 1, so that the second limit block 32 withdraws from the loading box 1. At the same time, the first limit block 31 is driven to insert into the loading box 1 through the connecting block 33 to prevent the subsequent camshaft 2 from falling out. After the support member 4 passes, the torsion spring automatically resets the discharge assembly, and the camshaft 2 in the discharge box is limited again to prevent the discharge box from falling out.

[0042] The detection device 53 includes a detection bracket 71 and a camera 72. In this embodiment, the camera 72 is industrially connected. The detection bracket 71 is fixedly mounted on the guard plate 512 through the mounting plate 15, and the camera 72 is fixedly mounted on the inner bottom of the detection bracket 71. A processor is provided on the detection bracket 71, and the processor is electrically connected to the camera 72. After the camshaft 2 moves below the detection bracket 71, the processor controls the camera 72 to work, and the camera 72 takes pictures of the four camshafts 2 below the detection bracket 71, compares the collected image with the standard image, and determines whether the camshaft 2 has defects, and controls the unloading device 54 to work according to the judgment result.

[0043] The unloading device 54 includes an unloading bracket 81, a cylinder 82, a hook, a first slide rail assembly 84 and a second slide rail assembly 85. The unloading bracket 81 is fixedly mounted on the guard plate 512, the cylinder 82 is fixedly mounted on the top of the cylinder 82, the cylinder 82 is electrically connected to the processor, a plate body 811 is provided on the unloading bracket 81, and the hook includes a connecting plate 831 and two hook bodies 832. Both ends of the plate body 811 are provided with through grooves, and the tops of the two hook bodies 832 pass through the two through grooves and connect to the connecting plate 831. 1 is fixedly connected, the output shaft of the cylinder 82 is fixedly connected to the connecting plate 831, the first slide rail assembly 84 and the second slide rail assembly 85 have the same structure, the first slide rail assembly 84 and the second slide rail assembly 85 are sequentially arranged below the plate body 811, the first slide rail assembly 84 includes two slide rails 841 with the same structure, and the ends of the slide rails 841 are hinged with a movable plate 86 through a torsion spring. In this embodiment, the movable plate 86 can only rotate upward to prevent the camshaft 2 on the movable plate 86 from falling back onto the hook body 832. When the camshaft 2 moves to the bottom of the unloading device 54, the processor controls the cylinder 82 to work, the cylinder 82 drives the hook to move upward, and lifts the camshaft 2 through the hook body 832, so that the defective camshaft 2 enters the first slide rail assembly 84, and the standard camshaft 2 enters the second slide rail assembly 85, completing the unloading.

[0044] The working principle of a camshaft detection system of the present invention is as follows: first, the positioning sleeves 21 are set at both ends of the camshaft 2, and the camshaft 2 is placed in the storage cavity 11 of the loading box 1. Subsequently, the plate chain conveyor 51 is controlled to work. When the plate chain conveyor 51 works, the camshaft 2 is driven to move through the conveying plate 511. When the support 4 passes through the discharging assembly, the arc block 472 squeezes the stopper 321 to move away from the loading box 1, so that the second limit block 32 withdraws from the loading box 1, and drives the first limit block 31 to be inserted into the loading box 1 through the connecting block 33, so that the camshaft 2 at the bottom falls on the support 4, and the first limit bar 421 is clamped in the limit groove 211. After the support 4 passes, the torsion spring automatically resets the discharging assembly, and limits the camshaft 2 in the discharging box again to prevent the camshaft 2 from falling out.

[0045] When the support 4 is located at the 0° shooting point, the camera 72 collects a 20° image of the camshaft, and then the support 4 continues to move; when the rack 43 moves from the top of the guard plate 512 to the first step surface 61, the drive plate 6 pushes the rack 43 upward, and the upward movement of the rack 43 pushes the gear 422 to rotate, thereby driving the camshaft 2 to rotate until the rack 43 is located on the first step surface 61. During this process, the camshaft 2 rotates 90°, and the camera 72 collects a 290° image of the camshaft, and collects 180° and 270° images in turn, achieving comprehensive collection and ensuring the detection effect. And the four camshafts 2 are detected at the same time, effectively improving the detection efficiency.

[0046] When the camshaft 2 moves to the bottom of the unloading device 54, the processor controls the cylinder 82 to work, and the cylinder 82 drives the hook to move upward, and lifts the camshaft 2 through the hook body 832, so that the defective camshaft 2 enters the first slide rail assembly 84, and the standard camshaft 2 enters the second slide rail assembly 85, completing the unloading.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
