Description

Technical Field

[0001] The present invention relates to the field of metal detection equipment, and specifically to a small cylinder liner detection device and a detection method. Background Art

[0002] The small cylinder liner, namely the abbreviation of the cylinder liner, is a component that is inserted into the cylinder barrel of the cylinder block and jointly forms a combustion chamber with the piston and the cylinder head. In order to ensure that the small cylinder liner meets its service performance after assembly, it is necessary to detect the outer surface of the small cylinder liner. The traditional detection method is to transfer one product at a time to the fixture on the turntable through a transfer mechanism, and then use the detection mechanism to detect the products in the fixture one by one. This detection method can only detect one product at a time, and the detection efficiency is not high.

[0003] In view of this, it is necessary to provide a small cylinder liner detection device and a detection method. Summary of the Invention

The end head of the first nut B extends into the strip-shaped card slot, and the end head of the first nut and the first gasket B clamp the baffle from both sides of the strip-shaped card slot respectively.

[0011] Further, the first transfer assembly and the second transfer mechanism have the same structure.

[0013] Furthermore, the detection component includes an end face detection unit and a circumferential surface detection unit, the end face detection unit includes a No. 3 seat arranged on the frame, a No. 3 linear module A arranged horizontally on the No. 3 seat, a No. 3 linear module B arranged vertically at the output end of the No. 3 linear module A, a connecting frame arranged at the output end of the No. 3 linear module B, and two No. 3 eddy current sensors arranged vertically on the connecting frame, the circumferential surface detection unit includes a No. 4 linear module arranged horizontally on the frame, a slide arranged at the output end of the No. 4 linear module, an adapter frame arranged on the slide, and a sensor component arranged at both horizontal ends of the adapter frame, the sensor component includes a number of No. 4 eddy current sensors A arranged on the adapter frame along the Z axis, and a number of No. 4 eddy current sensors B arranged on the adapter frame along the Z axis, the No. 4 eddy current sensors A and No. 4 eddy current sensors B are staggered up and down, and the No. 4 eddy current sensors A and No. 4 eddy current sensors B both extend along the radial direction of the product.

[0015] A small cylinder liner detection method adopts the small cylinder liner detection device described above. Two products flow out successively through the feeding mechanism to the flipping and transverse material receiving assembly, and then the first transfer assembly transfers the two products synchronously to the two fixtures. Subsequently, the turntable drives the two fixtures to the bottom of the detection mechanism under the drive of the indexer, so that the detection mechanism synchronously detects the upper end surface and circumferential surface of the products in the two fixtures. After the detection is completed, the second transfer mechanism transfers the two products synchronously to the discharge mechanism.

[0016] Beneficial effects of the invention:

[0017] 1. Use the flip and transverse material receiving assembly to receive two products in succession, and then use the first transfer assembly to move the two products synchronously to two fixtures. The detection mechanism simultaneously detects the two products, and the second transfer mechanism simultaneously unloads the two products, which can effectively improve the inspection efficiency of the products.

[0018] 2. When the flip and transverse material receiving assembly cooperates with the feeding mechanism, the flip material receiving mechanism uses two receiving troughs to receive two products of the feeding mechanism twice, which can reduce the design difficulty and manufacturing cost of the feeding mechanism.

[0019] 3. When the testing organization is testing two products, the staggered arrangement of No. 4 eddy current sensor A and No. 4 eddy current sensor B can maximize the number of sensors and detect points at different heights on the circumferential surface of the product, thereby increasing the testing area and the accuracy of the test.

[0020] 4. The structural design of the first material baffle assembly facilitates timely adjustment of the height and horizontal position of the baffle, enabling the baffle to provide lateral protection for products of different models. Description of the Drawings

Detailed implementation manners

[0030] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following provides a detailed description of the specific implementation manners of the present invention in conjunction with the accompanying drawings.

[0031] As Figure 1 shown, the first embodiment provided by the present application is a small cylinder liner detection device, the structure of which includes a frame 1, a turntable 2 arranged on the frame 1, a plurality of fixtures 3 circumferentially arranged on the turntable 2, a divider arranged on the frame 1 for driving the turntable 2 to rotate, a loading mechanism 4 arranged on one side of the frame 1, an unloading mechanism 5 arranged on the other side of the frame 1, a detection mechanism 6 arranged on the frame 1, a first transfer mechanism 7 and a second transfer mechanism 8. The first transfer mechanism 7 includes a flipping and transverse feeding assembly 71 arranged on the frame 1 and a first transfer assembly 72 arranged on the frame 1. The detection mechanism 6 synchronously detects the products 100 in two fixtures 3, and the first transfer assembly 72 simultaneously transfers two products 100 from the flipping and transverse feeding assembly 71 to the two fixtures 3.

[0032] During actual detection, two products 100 flow out through the feeding mechanism 4 one after another and into the flipping and transverse material receiving assembly 71. Then, the first transfer assembly 72 synchronously transfers the two products 100 to two fixtures 3. Subsequently, the turntable 2 drives the two fixtures 3 under the drive of the indexing device to the position below the detection mechanism 6, so that the detection mechanism 6 synchronously detects the upper end faces and circumferential faces of the products 100 in the two fixtures 3. After the detection is completed, the second transfer mechanism 8 synchronously transfers the two products 100 to the discharging mechanism 5.

[0033] In the above design, after the flipping and transverse material receiving assembly 71 receives the two products 100 one after another, the subsequent detection mechanism 6 synchronously detects the two products 100 in different fixtures 3. Compared with the method of detecting a single product 100, the present application can effectively improve the detection efficiency.

[0034] Specifically: as Figure 2 and Figure 3 shown, the flipping and transverse material receiving assembly 71 includes a first support 711 arranged on the frame 1, a rotating rod 712 rotatably arranged on the first support 711 and extending along the Y-axis direction, a first motor 713 arranged on the first support 711 to drive the rotating rod 712, a flipping frame 714 fixedly arranged on the rotating rod 712, a linear drive assembly 715 arranged on the flipping frame 714 and parallel to the rotating rod 712, and a material receiving plate 716 driven by the linear drive assembly 715. A plurality of material receiving grooves arranged along the Y-axis direction are provided on the material receiving plate 716. The linear drive assembly 715 can be a cylinder.

[0035] During actual use, the flipping and transverse material receiving assembly 71 needs to first receive the materials from the feeding mechanism 4. At this time, the first motor 713 drives the rotating rod 712 to rotate, driving the flipping frame 714 and the material receiving plate 716 to rotate to a position where the material receiving groove corresponds to the discharging port of the feeding mechanism 4, so that one of the material receiving grooves receives the product 100. Subsequently, the linear drive assembly 715 drives the material receiving plate 716 to move so that the other material receiving groove corresponds to the feeding mechanism 4. Then, the first motor 713 drives the rotating rod 712 to rotate, driving the flipping frame 714 and the material receiving plate 716 to rotate so that the material receiving groove faces upward. Then, the first transfer assembly 72 simultaneously transfers the two products 100 to two different fixtures 3.

[0036] In the above design, the structural design and specific implementation method of the flipping and transverse material receiving assembly 71 can realize the sequential material receiving of the two products 100, ensuring that the first transfer assembly 72 can transfer the two products 100 at one time.

[0037] Specifically: The first motor 713 drives the rotating rod 712 to rotate reciprocally. The rotating rod 712 drives the flipping frame 714 and the material receiving plate 716 to swing reciprocally. The material receiving plate 716 swings to a position where the opening of the material receiving groove faces the feeding mechanism 4 to receive the materials from the feeding mechanism 4. The linear driving assembly 715 drives the material receiving plate 716 to translate so that different material receiving grooves correspond to the feeding mechanism 4. After the material receiving plate 716 swings to a position where the opening of the material receiving groove faces upward, the first transfer assembly 72 picks up the product 100 in the material receiving groove.

[0038] Specifically: As Figure 7 shown, the feeding mechanism 4 includes a second support 41 arranged on the frame 1, a driving shaft arranged on the second support 41, a driven shaft arranged on the second support 41, a first belt 42 wound around the driving shaft and the driven shaft, a second motor 43 arranged on the second support 41 for driving the driving shaft to rotate, and a first material blocking assembly 44 arranged on the second support 41 and located on both sides of the first belt 42.

[0039] During actual feeding, multiple products 100 are arranged in a row on the upper end surface of the first belt 42. The second motor 43 drives the driving shaft, and the first belt 42 conveys the products 100 under the drive of the driven shaft, so that the products 100 flow into the material receiving groove along the first belt 42.

[0040] In the above design, the structural design and specific implementation manner of the feeding mechanism 4 can effectively realize the sequential feeding of the products 100.

[0041] Specifically: As Figure 8As shown in the figure, the first material baffle assembly 44 includes a mounting block 401 provided on the side of the second support 41 and having a lateral card slot, a first screw A 402 that is slidably lifted and lowered with the mounting block 401 and has an internal thread connection, a first eyebolt C 403 sleeved on the first screw A 402 and located in the lateral card slot, a first star nut C 404 threadedly connected to the first eyebolt C 403, a first washer C 405 provided between the first star nut C 404 and the first eyebolt C 403, a U-shaped joint 406 provided with a first vertical hole and a first horizontal through hole, a first nut A 407 passing through the first vertical hole and threadedly connected to the first screw A 402, a first washer A 408 sleeved on the first nut A 407 and located at the lower end of the first vertical hole, a first screw B 409 slidably arranged in the first horizontal hole and having an internal thread, a first nut B 410 threadedly connected to the first screw B 409, a first washer B 411 sleeved on the first nut B 410, a first eyebolt B 412 sleeved on the first screw B 409 and located inside the mounting block 401, a first star nut B 413 threadedly connected to the first eyebolt B 412, a first washer D 414 provided between the first star nut B 413 and the first eyebolt B 412, and a baffle 415 provided with a strip-shaped card slot. The end head of the first nut B 410 extends into the strip-shaped card slot, and the end head of the first nut B 410 and the first washer B 411 clamp the baffle 415 from both sides of the strip-shaped card slot.

[0042] Two first material baffle assemblies 44 partition both sides of the product 100 conveyed on the first belt 42 to prevent the product 100 from sliding off the first belt 42. The height and horizontal position of the baffle 415 can be adjusted in the following manner: By screwing the first star nut C 404 to loosen the first eyebolt C 403 from the first screw A 402, and then lifting and lowering the first screw A 402, so that the first screw A 402 drives the U-shaped joint 406, the first nut B 410, the first washer B 411, the first eyebolt B 412, the first star nut B 413, the first washer B 411, etc. to be lifted and lowered synchronously to a predetermined position, and then tightening the first star nut C 404 so that the first star nut C 404 abuts against the first washer C 405 and the first eyebolt C 403 laterally compresses the first screw A 402. When it is necessary to adjust the horizontal position of the baffle 415, by screwing the first star nut B 413 to loosen the first eyebolt B 412 from the first screw B 409, and then sliding the first screw B 409 along the first horizontal through hole to a predetermined position, driving the baffle 415 to move synchronously, and then tightening the first star nut B 413 again so that the first eyebolt B 412 clamps the first screw B 409 tightly.

[0043] In the above design, the structural design and specific implementation of the first material blocking component 44 facilitate the adjustment of the height and horizontal position of the baffle 415, so as to achieve lateral protection for products 100 of different models.

[0044] Specifically: As Figure 4 shown, the first transfer component 72 and the second transfer mechanism 8 have the same structure. The first transfer component 72 includes a first seat 721 arranged on the frame 1, a first linear module A 722 arranged on the first seat 721 along the X-axis direction, a first linear module B 723 arranged at the output end of the first linear module A 722 along the Z-axis direction, a first lifting frame 724 arranged at the output end of the first linear module B 723, and two cylinder grippers 725 arranged on the first lifting frame 724 along the Y-axis direction. The two cylinder grippers 725 are used to simultaneously grip and transfer two products 100.

[0045] During actual use, the first linear module A 722 drives the first linear module B 723 to move along the X direction, and the first linear module B 723 drives the first lifting frame 724 to lift and lower, so that the two cylinder grippers 725 move to the gripping position or the discharging position to synchronously grip or place the two products 100.

[0046] In the above design, the structural design and specific implementation of the first transfer component 72 and the second transfer mechanism 8 facilitate the synchronous movement of the two products 100.

[0047] Specifically: As Figure 5 and Figure 6 shown, the fixture 3 includes a bearing arranged on the turntable 2, a rotating shaft 31 connected to the inner ring of the bearing, a carrier seat 32 arranged at the upper end of the rotating shaft 31, and a first friction wheel 33 coaxially and fixedly arranged at the lower end of the rotating shaft 31. The detection mechanism 6 includes a detection component and two fixture rotation driving components symmetrically arranged on both sides of the detection component. The fixture rotation driving component includes a slide cylinder 611 arranged on the frame 1, a slide plate 612 arranged at the output end of the slide cylinder 611, a second friction wheel 613 rotatably arranged on the slide plate 612, and a motor pulley assembly 614 arranged on the slide plate 612 for driving the second friction wheel 613 to rotate.

[0048] During actual detection, when the turntable 2 is stationary and the jig 3 stays at a predetermined position, the slide table cylinder 611 drives the slide plate 612 to move towards the jig 3, causing the second friction wheel 613 to generate friction with the first friction wheel 33. Subsequently, the motor pulley assembly 614 drives the second friction wheel 613 to rotate, causing the first friction wheel 33 to rotate synchronously in the opposite direction, driving the rotating shaft 31 and the carrier seat 32 to rotate, thereby enabling the product 100 to rotate synchronously with the carrier seat 32. During the rotation of the product 100, the detection component remains stationary, realizing the relative movement between the detection component and the product 100, and thus detecting different positions of the product 100.

[0049] In the above design, the structural design and specific implementation of the jig 3 and the detection mechanism 6 can achieve the rotational drive of the product 100 and the detection during the rotation of the product 100.

[0050] Specifically: as Figure 5 and Figure 6 shown, the detection component includes an end face detection unit 62 and a circumferential face detection unit 63. The end face detection unit 62 includes a third seat 621 arranged on the frame 1, a third linear module A 622 horizontally arranged on the third seat 621, a third linear module B 623 vertically arranged at the output end of the third linear module A 622, a connecting frame 624 arranged at the output end of the third linear module B 623, and two third eddy current sensors 625 vertically arranged on the connecting frame 624. The circumferential face detection unit 63 includes a fourth linear module 631 horizontally arranged on the frame 1, a sliding seat 632 arranged at the output end of the fourth linear module 631, a transfer frame 633 arranged on the sliding seat 632, and a sensing component arranged at the horizontal two ends of the transfer frame 633. The sensing component includes a number of fourth eddy current sensors A 634 arranged along the Z-axis on the transfer frame 633 and a number of fourth eddy current sensors B 635 arranged along the Z-axis on the transfer frame 633. The fourth eddy current sensors A 634 and the fourth eddy current sensors B 635 are arranged in a staggered manner up and down, and both the fourth eddy current sensors A 634 and the fourth eddy current sensors B 635 extend along the radial direction of the product 100.

[0051] During actual detection, after the turntable 2 stops rotating, the connecting frame 624 is driven to move by the third linear module A 622 and the third linear module B 623, so that the third eddy current sensor 625 moves to a predetermined height. The sliding seat 632 is driven to move towards the jig 3 by the fourth linear module 631, so that the sensing component moves to a predetermined position, ensuring that the fourth eddy current sensors A 634 and the fourth eddy current sensors B 635 correspond to different positions on the circumferential face of the product 100.

[0052] In the above design, the structural design and specific implementation of the detection component facilitate the detection of defects on the circumferential face and the upper end face of the product 100.

[0053] Specifically: Figure 1 As shown, the discharge mechanism 5 includes a good product conveyor line 51 and a defective product conveyor line arranged on the frame 1, the defective product conveyor line includes a line 52 extending along the Y axis and a line 53 extending along the X axis and docking with the discharge end of the line 52, the good product conveyor line 51 extends along the X axis and is located on the side of the line 52 away from the turntable 2.

[0054] During actual unloading, defective products 100 are placed in line 1 52 by the second transfer mechanism 8 and transferred to line 2 53 , while qualified products 100 are transferred to the good product conveying line 51 by the second transfer mechanism 8 .

[0055] In the above design, since not all two products 100 tested in the same batch are defective, when only one is defective, the defective product 100 only needs to be transferred to line 1 52 for easy unloading.

[0056] The second embodiment provided by the present application is a small cylinder liner detection method. The small cylinder liner detection device is used. The two products 100 flow out successively through the loading mechanism 4 to the flipping and transverse material receiving component 71, and then the first transfer component 72 transfers the two products 100 synchronously to the two fixtures 3. Subsequently, the turntable 2 drives the two fixtures 3 to the bottom of the detection mechanism 6 under the drive of the indexer, so that the detection mechanism 6 synchronously detects the upper end surface and circumferential surface of the products 100 in the two fixtures 3. After the detection is completed, the second transfer mechanism 8 synchronously transfers the two products 100 to the discharge mechanism 5.

[0057] In the above design, it is possible to perform synchronous defect detection on two products 100 at the same time, effectively improving the efficiency of defect detection on the products 100.

[0058] To explain in further detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
