Description

Technical Field

[0001] This application relates to the field of workpiece inspection and processing, and in particular to a workpiece rotary inspection device. Background Technology

[0002] In the fields of machinery manufacturing and inspection, with the continuous development of industrial production, the demand for workpiece quality inspection and processing is increasing. Efficient and precise workpiece inspection and processing equipment is of paramount importance for improving production efficiency and ensuring product quality.

[0003] A workpiece includes a cylindrical body, which comprises a first columnar segment, a connecting columnar segment, and a second columnar segment. The connecting columnar segment has an inwardly recessed first ring portion, and the second columnar segment has a third hole portion along its axial direction. The production of this workpiece includes processes such as thickness measurement of the connecting columnar segment, outer diameter measurement of the first ring portion, and deburring of the third hole portion. In related technologies, thickness measurement typically employs a manual mechanical go / no-go gauge. The operator first holds a special caliper gauge and inserts the end of the go gauge, simulating the minimum thickness, between the first and second ring surfaces of the workpiece. If the go gauge passes smoothly, it indicates that the thickness does not exceed the minimum limit dimension. Subsequently, the operator inserts the end of the no-go gauge, simulating the maximum thickness, into the same area. If the no-go gauge cannot pass or causes significant interference with the workpiece, it indicates that the thickness does not exceed the maximum limit dimension. Combining the results of the two measurements, the thickness of the connecting columnar segment of the workpiece can be determined to be acceptable.

[0004] Regarding the aforementioned technologies, the inventors believe that the production mode described above has low efficiency and reliability in detecting the thickness of the connecting column sections of the workpiece. Summary of the Invention

[0005] To improve the efficiency and reliability of detecting the thickness of connecting column sections of workpieces, this application provides a workpiece rotary table inspection device.

[0006] The workpiece rotary inspection device provided in this application adopts the following technical solution:

[0007] A workpiece rotary table inspection device includes a rotary worktable with a drive motor for horizontal rotation. At least six mounting bases are circumferentially arranged on the upper surface of the rotary worktable. Sequentially arranged on the outer side of the rotary worktable are a loading device for mounting workpieces onto the mounting bases, a first detection device for detecting the thickness of a connecting ring portion of the workpiece, a second detection device for detecting the outer diameter of the first ring portion, a first unloading device for removing misaligned workpieces from the mounting bases, a deburring repair device for grinding burrs on a third hole portion of the workpiece, and a second unloading device for removing the repaired workpiece from the mounting bases. The loading device, the first detection device, the second detection device, the first unloading device, the deburring repair device, and the second unloading device are correspondingly arranged with respect to the mounting bases on the rotary worktable. Each mounting base has a through-beam extending from its upper and lower surfaces for supplying... The second column segment of the workpiece is placed in an arrangement through hole. The top of the mounting base is provided with a limiting protrusion to restrict the circumferential rotation of the workpiece. The inner side of the limiting protrusion includes an abutting side for the first side of the workpiece to abut against, and a guide surface connected to the top of the abutting side to guide the second column segment of the workpiece into the arrangement through hole. The first detection device includes a first detection mechanism, and the first detection mechanism is slidably provided with a first clamping plate. The first clamping plate has a clamping part for detecting the thickness of the connecting column segment of the workpiece. The top side of the clamping part has an abutting plane for the first annular surface to abut against. The bottom side of the clamping part has a stepped structure for the second annular surface to abut against. The stepped structure includes a first plane, a connecting side, and a second plane in sequence along the direction away from the workpiece. The first plane and the second plane are both arranged parallel to the abutting plane, and the distance between the first plane and the abutting plane is less than the distance between the second plane and the abutting plane.

[0008] By adopting the above technical solution, the first clamping plate with a stepped structure is integrated into the rotary table. After the workpiece is loaded, it flows to the first detection device station along with the rotary table. The first clamping plate automatically slides and detects the thickness of the workpiece. The workpiece that passes the detection flows to the lower burr repair device along with the rotary table, where the third hole of the workpiece is ground. The first clamping plate abuts against the first annular surface of the workpiece using the abutting plane, and abuts against the second annular surface of the workpiece using the first and second planes at different heights, thereby realizing the detection of the thickness tolerance of the connecting column section of the workpiece. When the thickness of the workpiece is qualified, the first annular surface abuts against the abutting plane, and the second annular surface just contacts the first plane without interfering with the second plane, thereby effectively judging whether the thickness is within the allowable tolerance range, which helps to improve detection efficiency and reliability.

[0009] Optionally, it also includes a conveyor table arranged on one side of the feeding device for inputting workpieces; the feeding device is used to install the workpieces on the conveyor table onto the mounting base, a first clamping mechanism for driving the first clamping mechanism to reciprocate between the conveyor table and the rotary table, and a first lifting mechanism for driving the first clamping mechanism to rise and fall; the conveyor table is provided with a first abutting block on one side wall of the output end for the first side of the workpiece to abut against; the first sliding mechanism includes a horizontally arranged horizontal slide rail, a horizontal slider arranged on the horizontal slide rail, and a horizontal driving member for driving the horizontal slider to reciprocate; the first lifting mechanism includes a vertically arranged first lifting slide rail, a first lifting slider arranged on the first lifting slide rail, and a first lifting cylinder for driving the first lifting slider to reciprocate; the first clamping mechanism includes two opposing first clamping plates and a first clamping cylinder for driving the two first clamping plates to open and close.

[0010] By adopting the above technical solution, a first abutting block that cooperates with the first side of the workpiece is set at the output end of the conveyor table, which realizes the initial alignment of the workpiece before loading. When the first clamping mechanism clamps the workpiece located at the output end of the conveyor table and places it on the corresponding mounting base, the first side of the workpiece can abut with the abutting side under the guiding action of the guide surface, which helps to improve the alignment effect when loading the workpiece.

[0011] Optionally, the first detection device further includes a second clamping mechanism for clamping a workpiece, a first rotary cylinder for driving the second clamping mechanism to rotate, and a second lifting mechanism for driving the second clamping mechanism to rise and fall; the second clamping mechanism includes a rotating base plate arranged on the first rotary cylinder and two clamping assemblies symmetrically arranged on the rotating base plate; the clamping assembly includes two opposing second clamping plates and a second clamping cylinder arranged on the rotating base plate and driving the two second clamping plates to open and close; the first detection mechanism further includes a detection platform, a sliding seat arranged on one side of the detection platform for sliding the first clamping plate, and a driving assembly arranged on the sliding seat for driving the first clamping plate to move along the length direction; the detection platform has an arrangement slot for placing a workpiece, and the detection platform has a second abutment block on the side of the arrangement slot facing the first clamping plate for the first side of the workpiece to abut against.

[0012] By adopting the above technical solution, in the thickness detection process, the first clamping plate moves towards the detection table under the drive of the drive component, and the thickness of the connecting ring of the workpiece is detected by the stepped structure; the second abutment block that cooperates with the first side of the workpiece after it has turned is set on the detection table, which helps to improve the alignment effect of the workpiece, reduces the risk of the workpiece turning during the thickness detection process and affecting the detection results, and ensures the placement efficiency of the workpiece in subsequent processes.

[0013] Optionally, the snap-fit ​​portion has a first snap-fit ​​groove corresponding to the arrangement groove and used for snapping the connecting column segment of the workpiece; the first snap-fit ​​plate has a sliding portion, and the sliding portion has limiting protrusions extending along the length direction on both sides; the sliding seat has a sliding groove for the limiting protrusions to slide and arrange; the top side of the sliding portion has a positioning post, and the sliding seat has a second sensor for detecting the position of the positioning post.

[0014] By adopting the above technical solution, the first slot of the snap-fit ​​part snaps the workpiece connecting column segment, and the abutting plane abuts against the first annular surface. When the first snap-fit ​​plate slides towards the inspection table, the first plane and the second plane will abut against the second annular surface in sequence. During the movement, the positioning column moves along the sliding direction and cooperates with the second sensor. The snap-fit ​​position between the snap-fit ​​part and the workpiece is detected by the stopping position of the positioning column, thereby accurately detecting whether the thickness of the workpiece connecting column segment is within the qualified range.

[0015] Optionally, the second detection device includes a second sensor, the height of the sensing end of the second sensor being consistent with the height of the first ring when the workpiece is placed upright, and the extension line of the sensing end of the second sensor intersecting the axial projection of the workpiece at the first ring.

[0016] By adopting the above technical solution, in the outer diameter detection process, the sensing end of the second sensor emits infrared light towards the first ring of the workpiece. After the infrared light contacts the side wall of the first ring, it returns a signal to the second sensor, thereby realizing the automatic detection of the outer diameter of the first ring of the workpiece.

[0017] Optionally, it also includes a first unloading platform arranged on one side of the first unloading device for outputting workpieces that fail inspection; the first unloading device includes a third clamping mechanism for conveying workpieces on the mounting base to the first unloading platform, a third lifting mechanism for driving the third clamping mechanism to rise and fall, and a first rotating mechanism for driving the third clamping mechanism to reciprocate between the first unloading platform and the rotary table; the first rotating mechanism includes a first rotating arm and a second rotating cylinder for driving the first rotating arm to rotate; the third clamping mechanism includes two opposing third clamping plates and a third clamping cylinder arranged at the movable end of the first rotating arm for driving the two third clamping plates to open and close.

[0018] By adopting the above technical solution, in the first unloading process, the workpiece that is detected as unqualified is left from the mounting base under the clamping of the third clamping mechanism, and the workpiece is lifted and rotated 90° clockwise by the third lifting mechanism and the first rotating mechanism so that the workpiece is accurately moved to the first unloading table and output; the third clamping plate opens and closes under the drive of the third clamping cylinder to realize the clamping and releasing of the workpiece, thus realizing the automatic unloading of the workpiece.

[0019] Optionally, the burr repair device includes a positioning mechanism for pressing the workpiece against the mounting base and a grinding mechanism for grinding the lower surface of the workpiece; the positioning mechanism includes a clamping member facing the arrangement through hole and a second lifting cylinder for driving the clamping member to rise and fall; the grinding mechanism includes a grinding member, a first motor for driving the grinding member to rotate, and a third lifting cylinder for driving the grinding member to rise and fall; the rotation axis of the grinding member coincides with the axis of the clamping member; the rotary worktable has a central through hole corresponding to the arrangement through hole and for the grinding member to pass through.

[0020] By adopting the above technical solution, in the deburring process, the workpiece that has passed the inspection is pressed against the mounting base by the positioning mechanism. The grinding part located at the bottom of the rotary table is lifted and extended into the third hole located at the central through hole under the drive of the third lifting cylinder. Under the drive of the first motor, it rotates and grinds the inner surface of the third hole. The clamping part is pressed down and depressurized by the second lifting cylinder, realizing the automatic clamping of the workpiece, which helps to improve the grinding accuracy.

[0021] Optionally, it also includes a second unloading platform arranged on one side of the second unloading device for outputting the deburred workpiece; the second unloading device includes a fourth clamping mechanism for conveying the workpiece on the mounting base to the second unloading platform, a fourth lifting mechanism for driving the fourth clamping mechanism to rise and fall, and a second rotating mechanism for driving the fourth clamping mechanism to reciprocate between the second unloading platform and the rotary table; the second rotating mechanism includes a second rotating arm and a third rotating cylinder for driving the second rotating arm to rotate; the fourth clamping mechanism includes two opposing fourth clamping plates and a fourth clamping cylinder arranged at the movable end of the second rotating arm and driving the two fourth clamping plates to open and close.

[0022] By adopting the above technical solution, in the second unloading process, the qualified workpiece after deburring leaves the mounting base under the clamping of the fourth clamping mechanism, and the workpiece is lifted and rotated 90° counterclockwise through the fourth lifting mechanism and the second rotating mechanism, so that the workpiece is accurately moved to the second unloading table and output; the fourth clamping plate opens and closes under the drive of the fourth clamping cylinder to realize the clamping and releasing of the workpiece, thus realizing the automatic unloading of the workpiece.

[0023] Optionally, the mounting base has a rotating base, the rotating base having a rotating protrusion circumferentially arranged on its outer edge, the rotating worktable having a rotating groove for arranging the rotating protrusion and a rotating bearing arranged inside the rotating groove for rotatably engaging the rotating protrusion; the rotating worktable has a limiting post at the bottom of the rotating annular groove, the bottom side of the rotating protrusion having an arc-shaped elongated hole for inserting the limiting post circumferentially, and a reset structure for aligning the mounting base is provided between the limiting post and the arc-shaped elongated hole.

[0024] If the workpiece is slightly deflected during the placement process, i.e., the first side is not parallel to the abutting side, the third ring of the workpiece will interfere with the limiting protrusion of the mounting base, which may easily lead to the workpiece not being placed in the correct position.

[0025] By adopting the above technical solution, when interference occurs, the mounting base will tend to deflect away from the direction of interference, and the rotating protrusion of the mounting base will rotate under the cooperation of the rotating bearing, thereby causing the position of the limiting post in the limiting elongated hole to shift, realizing the flexible rotation of the mounting base on the rotary worktable; when the workpiece is placed in the correct position, that is, when the second annular surface is in contact with the top surface of the mounting base, the position of the limiting post in the limiting elongated hole returns to its original position under the drive of the reset structure, the mounting base rotates in the opposite direction and automatically returns to the correct position, ensuring the accuracy and stability of the workpiece's position on the mounting base.

[0026] Optionally, the reset structure includes a limiting ball head disposed at the end of the limiting post, a limiting arc groove disposed at the bottom of the arc-shaped elongated hole for the limiting ball head to abut against, and an elastic reset member for driving the limiting ball head to move closer to the top of the limiting arc groove; the limiting arc groove includes an arc segment and two adjusting segments connected to both ends of the arc segment; the middle part of the arc segment coincides with the highest point of the arc segment, and the depth of the adjusting segments gradually decreases in the direction away from the arc segment.

[0027] By adopting the above technical solution, when a slight deflection occurs during the placement of the workpiece, the rotating protrusion of the mounting base rotates within the rotating groove, and the contact point of the limiting ball head moves from the middle of the arc segment to the adjustment segment. The elastic reset component is compressed by the downward pressure of the limiting ball head. After the workpiece is placed correctly, under the action of the elastic reset component, the highest point of the limiting ball head is reset from the adjustment segment to the middle of the arc segment, and the mounting base and the workpiece return to their correct positions. The depth variation design of the adjustment segment can guide the limiting ball head back to the highest point of the arc segment under different offset conditions, which helps to accurately reset the mounting base.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. A workpiece rotary table inspection device, comprising a rotary worktable, a feeding device, a first inspection device, a second inspection device, a first unloading device, a burr removal and repair device, and a second unloading device; a first clamping plate with a stepped structure is integrated into the rotary worktable. When the workpiece flows to the station of the first inspection device along with the rotary worktable, the first clamping plate automatically slides to perform inspection; the first clamping plate abuts against the first annular surface of the workpiece using an abutting plane, and abuts against the second annular surface of the workpiece using a first plane and a second plane at different heights, thereby realizing the inspection of the thickness tolerance of the connecting column section of the workpiece; when the workpiece thickness is qualified, the first annular surface abuts against the abutting plane, and the second annular surface just contacts the first plane without interfering with the second plane, thereby effectively determining whether the thickness is within the allowable tolerance range, which helps to improve inspection efficiency and reliability;

[0030] 2. A first abutting block that mates with the first side of the workpiece is set at the output end of the conveyor table, which realizes the initial alignment of the workpiece before loading. When the first clamping mechanism clamps the workpiece located at the output end of the conveyor table and places it on the corresponding mounting base, the first side of the workpiece can abut with the abutting side under the guiding action of the guide surface, which helps to improve the alignment effect when loading the workpiece.

[0031] 3. When interference occurs, the mounting base tends to deflect away from the direction of interference, and the rotating protrusion of the mounting base rotates under the cooperation of the rotating bearing. This causes the position of the limiting post within the limiting elongated hole to shift, enabling the mounting base to rotate flexibly on the rotary worktable. When the workpiece is placed in the correct position, i.e., when the second annular surface is in contact with the top surface of the mounting base, the position of the limiting post within the limiting elongated hole returns to its original position under the drive of the reset structure. The mounting base rotates in the opposite direction and automatically returns to the correct position, ensuring the accuracy and stability of the workpiece's position on the mounting base.

[0079] The implementation principle of a workpiece rotary table inspection device according to an embodiment of this application is as follows: When inspecting and deburring workpiece 1, the feeding device 4 clamps workpiece 1 and places it on the corresponding mounting base 35 so that the second column section 112 of workpiece 1 is arranged in the arrangement through hole 3511. The drive motor 33 drives the rotary table 3 to rotate clockwise to the first inspection device 5, and the thickness of the connecting column section 113 of workpiece 1 is inspected by the first inspection device 5. After the inspection is completed, the drive motor 33 drives the rotary table 3 to rotate clockwise again so that the mounting base 35 is aligned with the second inspection device 6. The outer diameter of the first ring 1131 of workpiece 1 is inspected by the second inspection device 6. After the inspection is completed, the drive motor 33 drives the rotary table 3 to rotate clockwise to the first unloading device 7, and the first unloading device 7 unloads the workpiece 1 that fails the inspection. The qualified workpiece 1 continues to rotate clockwise under the drive of the drive motor 33 to the lower burr repair device 8. The lower burr repair device 8 grinds the inner wall of the third hole 123 of the workpiece 1. After grinding, the drive motor 33 drives the rotary worktable 3 to rotate to the second unloading device 9. The second unloading device 9 collects the qualified products after deburring, realizing the integrated processing of thickness detection and deburring. The first detection device 5 uses the first clamping plate 56 with a stepped structure to abut against the first annular surface 114 of the workpiece 1 with the abutting plane 5621, and uses the first plane 5622 and the second plane 5623 of different heights to abut against the second annular surface 115 of the workpiece 1, thereby realizing the detection of the thickness tolerance of the connecting column section 113 of the workpiece 1, effectively determining whether the thickness is within the allowable tolerance range, which helps to improve detection efficiency and reliability.

Under the action of gravity and guided by the guide surface 3532, the workpiece 1 smoothly enters the correct position. Similarly, when the second clamping plate 5521 sends the workpiece 1 on the inspection table 521 back to the mounting base 35 at the second station 212, the workpiece 1 will also automatically return to the correct position under the guidance of the guide surface 3532.
