Description

Technical Field

[0001] The invention belongs to the technical field of turning processing of a reducer output shaft group, and in particular relates to a full-automatic turning processing system for a reducer output shaft group. Background Art

[0002] When the reducer output shaft group (hereinafter referred to as the workpiece) is turned, the specific operation steps include: loading - single-side turning - flipping - single-side turning - inspection.

[0003] Among them, when loading, the operator needs to place the workpieces one by one to the required angle, otherwise the turning quality will be affected. This not only increases labor intensity and affects loading efficiency, but also the placement angle of the workpiece cannot be guaranteed, which directly affects the turning quality of the product.

[0004] In addition, during the inspection, it is necessary to measure the parameters such as the outer diameter, thickness and inner diameter of the finished workpiece. However, the existing inspection equipment is generally a split structure, that is, after one item is inspected, the workpiece needs to be moved to the inspection equipment on the other side. The entire inspection process requires the workpiece to be moved and positioned multiple times, which is not only time-consuming and labor-intensive, but also has low inspection efficiency. In addition, it is very easy to affect the accuracy of the inspection results due to positioning deviation. Summary of the Invention

DETAILED DESCRIPTION

[0070] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 making creative efforts shall fall within the scope of protection of the present invention.

[0071] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0072] like Figure 1-15 As shown, a fully automatic turning processing system for a reducer output shaft group includes a loading mechanism 1, a turning machine, a flipping mechanism 2, a detection mechanism 3 and a robot 4. The loading mechanism 1 includes a stacking component 11, a lifting component 12 and a moving component 13 for automatic loading of workpieces, and an angle adjustment component 14 for rotating the workpiece to a desired angle; two turning machines are provided for turning the end face, outer diameter and inner diameter of the workpiece; the flipping mechanism 2 includes two oppositely arranged flipping jaws, which can flip the semi-finished workpiece processed on one of the turning machines to suit the secondary processing of the other turning machine; the detection mechanism 3 includes a conveying component 31, an outer diameter measuring component 32, a thickness measuring component 33 and an inner diameter measuring component 34, for detecting whether the outer diameter, thickness and inner diameter of the finished workpiece are qualified; the robot 4 is used to transfer the workpiece between the loading mechanism 1, the turning machine, the flipping mechanism 2 and the detection mechanism 3.

[0073] In this embodiment, two turning machines are arranged opposite to each other, the loading mechanism 1 is located on the left side of the turning machine tool I5, the detection mechanism 3 is located on the right side of the turning machine tool II6, the flipping mechanism 2 is located at the opening of the turning machine tool I5, and the robot 4 is located between the two turning machines, so as to facilitate the transfer of the workpiece on the loading mechanism 1 to the turning machine tool I5, the transfer of the semi-finished workpiece in the turning machine tool I5 to the flipping mechanism 2, the transfer of the semi-finished workpiece on the flipping mechanism 2 to the turning machine tool II6, and the transfer of the finished workpiece in the turning machine tool II6 to the detection mechanism 3.

[0074] In addition, a protective net 7 connected to the outside of the two turning machines is provided on the side where the feeding mechanism 1 and the detection mechanism 3 are located, so as to ensure the safety of the turning system during operation.

[0075] The feeding mechanism 1 further includes a feeding platform 15 , on which the stacking assembly 11 , the lifting assembly 12 , the moving assembly 13 and the angle adjustment assembly 14 are all mounted.

[0076] The stacking assembly 11 is used to store workpieces to be processed. To achieve this function, the stacking assembly 11 includes a rotating tray 11 - 1 and a plurality of stacking columns 11 - 2 arranged in a ring shape on the rotating tray 11 - 1 .

[0077] Multiple layers of workpieces can be placed on each stacking column 11 - 2 . By rotating each stacking column 11 - 2 to the lifting assembly 12 , the workpieces on the stacking column 11 - 2 can be taken out one by one through the lifting assembly 12 in cooperation with the material moving group and transferred to the angle adjustment assembly 14 .

[0078] Preferably, a window is provided on the protective net 7 where the stacking assembly 11 is located, which is opposite to the position of the rotating material tray 11-1, so that the workpiece can be put on the stacking column 11-2 outside the protective net 7, and the operation is safer and more convenient.

[0079] In order to realize the rotation of the rotating material tray 11-1, a dividing motor (not shown in the figure) for driving the rotating material tray 11-1 is provided below the rotating material tray 11-1.

[0080] The indexing motor drives the rotary material tray 11 - 1 to rotate a fixed angle each time, so that the workpieces on each stacking column 11 - 2 can complete the loading operation.

[0081] For example, if six stacking columns 11 - 2 are evenly arranged on the rotary tray 11 - 1 , the rotary tray 11 - 1 rotates 60° each time to ensure that one stacking column 11 - 2 is opposite to the material lifting assembly 12 each time it rotates.

[0082] The indexing motor can be installed in the driving cavity 11-3 at the bottom of the rotating material tray 11-1.

[0083] In addition, the driving part is not limited to the indexing motor, and the combination of a motor and a cam can also be selected, that is, after the motor drives the cam to rotate, the rotating material tray 11-1 rotates a fixed angle every time the cam rotates one circle.

[0084] In order to support the workpiece and facilitate the subsequent lifting assembly 12 to lift the workpiece, a supporting step 11 - 4 is provided at the bottom of the stacking column 11 - 2 .

[0085] The stacking column 11 - 2 passes through the center hole of the workpiece, and the outer diameter of the supporting step 11 - 4 is larger than the center hole of the workpiece, which prevents the workpiece from falling and ensures the smooth lifting of the subsequent workpiece.

[0086] The lifting assembly 12 is used to lift the workpiece on the stacking column 11-2 to a set height and grab the workpiece with the moving assembly 13. In order to achieve the cooperation between the lifting assembly 12 and the stacking assembly 11, the lifting assembly 12 is set on one side of the stacking assembly 11;

[0087] In order to lift the workpiece on the stacking column 11 - 2 without affecting the rotation of the rotating material tray 11 - 1 , the lifting assembly 12 includes a lifting plate 12 - 1 that can move up and down and toward the stacking assembly 11 .

[0088] The lifting plate 12-1 extends into the bottom of the lowest layer of workpieces, and lifts the workpieces by its rise, so as to facilitate the grabbing of the material moving assembly 13. When the workpieces on a stacking column 11-2 are loaded, the rotary material tray 11-1 rotates and needs to switch to the next stacking column 11-2 with workpieces. At this time, the lifting plate 12-1 needs to move away from the rotary material tray 11-1 to avoid blocking the rotation of the stacking column 11-2. After the stacking column 11-2 with workpieces moves into place, the lifting plate 12-1 moves toward the stacking assembly 11 again and extends to the bottom of the lowest layer of workpieces, making it easier to lift the workpieces.

[0089] In order to enable the lifting plate 12-1 to extend outward and retract inward, the lifting assembly 12 also includes a telescopic cylinder 12-2 with a piston rod arranged toward the stacking assembly 11, and the lifting plate 12-1 is installed at the end of the piston rod of the telescopic cylinder 12-2.

[0090] The piston rod of the telescopic cylinder 12-2 is extended, so that the lifting plate 12-1 is matched with the corresponding stacking column 11-2. By raising the lifting plate 12-1, the workpiece on the stacking column 11-2 can be lifted; and when the piston rod of the telescopic cylinder 12-2 is retracted, the lifting plate 12-1 is retracted from the stacking column 11-2, and the stacking column 11-2 can rotate under the drive of the rotating material tray 11-1, and the lifting plate 12-1 will not interfere with it.

[0091] In order to realize the lifting and lowering of the lifting plate 12-1, the lifting assembly 12 also includes a lifting frame 12-3, a lifting motor 12-4 installed on the top of the lifting frame 12-3, and a lifting screw rod 12-5 vertically arranged in the lifting frame 12-3 and connected to the lifting motor 12-4. The lifting plate 12-6 is connected to the nut of the lifting screw rod 12-5, and the telescopic cylinder 12-2 is installed at the bottom of the lifting plate 12-6.

[0092] A motor mounting frame Ⅰ12-7 is installed on the top of the lifting frame 12-3, and the lifting motor 12-4 is installed on the motor mounting frame Ⅰ12-7, and its output shaft is connected to the lifting screw rod 12-5 through couplings and other connecting parts. The lifting motor 12-4 drives the lifting screw rod 12-5 to rotate, thereby driving the lifting plate 12-6, the telescopic cylinder 12-2 and the lifting plate 12-1 to rise and fall synchronously.

[0093] Preferably, an outwardly extending expansion chamber 12-8 is provided on the side of the lifting frame 12-3 facing away from the stacking assembly 11, so as to provide space for the lifting and lowering of the telescopic cylinder 12-2.

[0094] Preferably, a linear slide rail (not shown in the figure) parallel to the lifting screw rod 12-5 is provided on the inner side wall of the lifting frame 12-3, and linear sliders cooperating with the linear slide rail are provided on both sides of the lifting plate 12-6 to play a guiding role when the lifting plate 12-6 is raised or lowered.

[0095] Preferably, a linear slide rail (not shown in the figure) parallel to the piston rod of the telescopic cylinder 12-2 is provided at the bottom of the lifting plate 12-6, which can cooperate with the linear slider on the upper surface of the lifting plate 12-1 to play a guiding role when the lifting plate 12-1 is extended or retracted.

[0096] In order to achieve the cooperation between the lifting plate 12-1 and the stacking column 11-2, a U-shaped notch 12-9 is provided at the outer end of the lifting plate 12-6.

[0097] The width of the U-shaped notch 12-9 is not less than the width of the supporting step 11-4, but is smaller than the outer diameter of the workpiece, so that it can cooperate with the stacking column 11-2 while ensuring the lifting of the workpiece.

[0098] When the workpiece needs to be lifted, the lifting plate 12-1 is extended by the telescopic cylinder 12-2, and the stacking column 11-2 is fitted into the U-shaped notch 12-9. At this time, the lifting plate 12-1 rises to lift the workpiece.

[0099] The material moving assembly 13 can grab the workpiece lifted by the material lifting plate 12 - 1 and transfer it to the angle adjustment assembly 14 . Therefore, the material moving assembly 13 is arranged above the material stacking assembly 11 and opposite to the material lifting assembly 12 .

[0100] The material moving assembly 13 includes a material moving claw 13 - 1 that can move up, down, and horizontally.

[0101] When the material moving claw 13-1 grabs the workpiece, it not only needs to lift the workpiece by the lifting plate 12-1, but also needs to lower the material moving claw 13-1 to a certain extent to prevent the stacking assembly 11 from interfering with the subsequent lateral movement of the material moving claw 13-1. The translation of the material moving claw 13-1 is to move the workpiece from above the stacking column 11-2 to above the angle adjustment assembly 14.

[0102] In order to realize the lifting and lowering of the material moving claw 13-1, the material moving assembly 13 also includes a lifting bracket 13-2, a lifting motor 13-3 installed on the top of the lifting bracket 13-2, and a lifting screw 13-4 vertically arranged on the side of the lifting bracket 13-2 facing the material lifting assembly 12 and connected to the lifting motor 13-3. The nut of the lifting screw 13-4 is connected to the lifting plate I 13-5, and the material moving claw 13-1 is fixed to the bottom of the lifting plate I 13-5.

[0103] The lifting motor 13-3 and the lifting screw 13-4 are arranged on the side of the lifting bracket 13-2 facing the lifting component 12. When the lifting plate 12-1 lifts the workpiece to the specified height, the lifting motor 13-3 drives the lifting screw 13-4 to rotate, thereby driving the material moving claw 13-1 to descend through the lifting plate I 13-5 to grab the workpiece. After the grabbing is completed, the material moving claw 13-1 rises and resets again.

[0104] Preferably, the lifting bracket 13-2 is provided with two vertically arranged vertical plates Ⅰ13-6 on the side facing the lifting component 12, and the vertical plate Ⅰ13-6 is provided with a linear slide rail (not shown in the figure) parallel to the lifting screw 13-4, and the lifting plate Ⅰ13-5 is provided with a linear slider that cooperates with the linear slide rail, which plays a guiding role when the lifting plate Ⅰ13-5 and the material moving claw 13-1 are raised and lowered.

[0105] Preferably, the material moving claw 13-1 is a cylinder clamp.

[0106] After grabbing the workpiece, the material moving claw 13-1 needs to be moved to the angle adjustment assembly 14 to adjust its angle for subsequent turning machine processing. In order to realize the transverse movement of the material moving claw 13-1, the material moving assembly 13 also includes a transverse frame 13-7, a transverse screw rod 13-8 installed on the crossbeam of the transverse frame 13-7, and a transverse motor 13-9 connected to one end of the transverse screw rod 13-8. The nut of the transverse screw rod 13-8 is connected to the lifting bracket 13-2.

[0107] The transverse moving frame 13-7 is a gate-shaped frame, and the transverse moving screw 13-8 is installed above the crossbeam of the transverse moving frame 13-7. The transverse moving motor 13-9 is fixed to one end of the transverse moving screw 13-8. The transverse moving motor 13-9 drives the transverse moving screw 13-8 to rotate to realize the transverse movement of the lifting bracket 13-2, thereby moving the material moving claw 13-1 after grabbing the workpiece from above the stacking column 11-2 to above the angle adjustment component 14.

[0108] Preferably, a linear slide rail (not shown in the figure) parallel to the transverse screw rod 13-8 is provided on the side of the crossbeam of the transverse frame 13-7 facing the lifting assembly 12, and a linear slider that cooperates with the linear slide rail is installed on the lifting bracket 13-2, which can guide the lifting bracket 13-2 when it moves transversely.

[0109] In order to detect whether the material moving claw 13 - 1 has grasped the workpiece, opposite photoelectric sensors I 13 - 10 are provided on both sides of the material moving claw 13 - 1 .

[0110] Specifically, the photoelectric sensor I 13 - 10 is mounted on the loading platform 15 through a fixing rod 13 - 11 , and its height is the same as the height of the material moving claw 13 - 1 when grabbing the workpiece.

[0111] One of them is the transmitting end of the photoelectric sensor Ⅰ13-10, and the other is the receiving end of the photoelectric sensor Ⅰ13-10. After the material moving claw 13-1 grabs the workpiece, if the receiving end does not receive the light emitted by the transmitting end, it means that the material moving claw 13-1 has grabbed the workpiece. If the receiving end receives the light emitted by the transmitting end, it means that the surface material moving claw 13-1 has not grabbed the workpiece.

[0112] Photoelectric sensor Ⅰ13-10 can be selected from but not limited to the photoelectric sensor of model E3ZG-T61-D / L.

[0113] In order to facilitate receiving the workpieces removed from the stacking column 11 - 2 , the angle adjustment assembly 14 is arranged on one side of the stacking assembly 11 and is located on the side of the moving assembly 13 facing the lifting assembly 12 .

[0114] In order to realize the rotation of the workpiece so as to rotate it to its required angle, the angle adjustment assembly 14 includes an adjustment frame 14-1, a turntable 14-2 arranged above the adjustment frame 14-1, and an adjustment motor 14-3 arranged below the adjustment frame 14-1 and connected to the turntable 14-2.

[0115] Specifically, a motor fixing frame 14-4 is installed below the adjustment frame 14-1, the adjustment motor 14-3 is fixed on the motor fixing frame 14-4, and its output shaft is connected to the turntable 14-2 set at the top of the adjustment frame 14-1 to drive the workpiece on the turntable 14-2 to rotate.

[0116] In order to position the angle of the workpiece on the turntable 14-2 to ensure the accuracy of the direction of the workpiece, a detection cylinder 14-5 with a piston rod facing the angle adjustment component 14 is provided on the material moving assembly 13, and an infrared probe 14-6 that can be moved to the top of the turntable 14-2 is installed at the end of the piston rod of the detection cylinder 14-5.

[0117] Specifically, the detection cylinder 14-5 is installed on a vertical beam on one side of the transverse frame 13-7 close to the angle adjustment component 14. After the workpiece is placed on the turntable 14-2, the piston rod of the detection cylinder 14-5 is extended, so that the infrared probe 14-6 moves to the top of the workpiece to detect the workpiece. At other times, the piston rod of the detection cylinder 14-5 is retracted to prevent the infrared probe 14-6 from affecting the material moving of the material moving claw 13-1 and the placement of the workpiece.

[0118] Multiple eccentric holes are evenly arranged around the center hole on the workpiece. The infrared probe 14-6 can convert the detected analog data into a digital signal, that is, when the infrared probe 14-6 is opposite to the eccentric hole, the digital signal obtained is "0", and it is "1" in other cases.

[0119] When the workpiece is placed on the turntable 14-2 and rotated, the infrared probe 14-6 starts recording when it receives the "0" signal, and starts timing when it switches to the "1" signal. At this time, after rotating for a certain period of time, the turntable 14-2 can be controlled to stop rotating. At this time, the workpiece has rotated to the required angle direction.

[0120] When switched to the "1" signal, the angle of rotation of the workpiece can be determined by adjusting the rotation time and the rotation speed of the motor 14-3, thereby ensuring the accuracy of the direction of the workpiece.

[0121] The infrared probe 14-6 may be, but is not limited to, the infrared probe 14-6 of model LA-ZB030N.

[0122] In order to facilitate the detection of whether a workpiece is placed on the turntable 14-2, a relative photoelectric sensor II 14-7 is installed on the opposite side of the adjustment frame 14-1.

[0123] The working principle of photoelectric sensor II 14-7 is the same as that of photoelectric sensor I 13-10.

[0124] Photoelectric sensor II 14-7 can be selected from but not limited to the photoelectric sensor of model E3ZG-T61-D / L.

[0125] The robot 4 grabs the workpiece to be processed from the loading mechanism 1 and places it in the turning machine tool I5. The turning machine tool I5 can process one end face of the workpiece, as well as the outer diameter and inner diameter close to the end face, that is, single-sided turning; after this part of the processing is completed, the semi-finished workpiece needs to be turned over to facilitate its placement in the turning machine tool II6 to process the other end face, as well as the outer diameter and inner diameter close to the other end face, that is, single-sided turning of the other side.

[0126] In order to realize the turning over of the workpiece, the turning mechanism 2 further includes a fixed turning bracket 21 for mounting the turning clamp and a movable turning bracket 22 . The movable turning bracket 22 can move toward the fixed turning bracket 21 .

[0127] The robot 4 transfers the semi-finished workpiece taken out from the turning machine tool Ⅰ5 to the flipping mechanism 2, and holds it in the flipping clamp Ⅰ23 on the fixed flipping bracket 21, and then the movable flipping bracket 22 drives the flipping clamp Ⅱ24 on its top to move toward the fixed flipping bracket 21, and then clamps the semi-finished workpiece. At this time, the flipping clamp Ⅰ23 releases the workpiece, and the movable flipping bracket 22 drives the flipping clamp Ⅱ24 and the semi-finished workpiece clamped by the flipping clamp Ⅱ24 to move and reset. At this time, the robot 4 can remove the semi-finished workpiece on the flipping clamp Ⅱ24 and transfer it to the turning machine tool Ⅱ6 for secondary processing.

[0128] The flipping clamp is a three-jaw cylinder clamp, and the clamping jaws of the two flipping clamps are staggered, so that the transfer of the semi-finished workpiece between the two flipping clamps can be achieved.

[0129] In order to realize the movement of the movable flip bracket 22, the flip mechanism 2 also includes a flip bracket moving screw 25 located on one side of the movable flip bracket 22, and a flip bracket moving motor 26 connected to one end of the flip bracket moving screw 25, and the movable flip bracket 22 is connected to the nut of the flip bracket moving screw 25.

[0130] The flip bracket moving motor 26 rotates, driving the flip bracket moving screw 25 to rotate, thereby causing the movable flip bracket 22 connected to the nut to move linearly in the axial direction of the flip bracket moving screw 25 .

[0131] Preferably, the flipping mechanism 2 also includes a base plate 27, on which a linear guide rail Ⅰ28 parallel to the flip bracket moving screw 25 is installed, and a slider Ⅰ29 cooperating with the linear guide rail Ⅰ28 is installed at the bottom of the movable flip bracket 22 to facilitate guidance when the movable flip bracket 22 moves.

[0132] Preferably, a dust cover I 210 is provided above the flip bracket moving motor 26 and the flip bracket moving screw rod 25 .

[0133] After the workpiece has been turned twice, its various parameters need to be tested to ensure that it meets the qualified standards, so a testing mechanism 3 is set up.

[0134] The detection mechanism 3 also includes a detection platform 35, on which the conveying component 31, outer diameter measuring component 32, thickness measuring component 33 and inner diameter measuring component 34 are respectively installed, and each detection component is covered with a transparent dust cover 36 for dust protection of each detection component to ensure detection accuracy.

[0135] In this embodiment, outer diameter measurement assembly 32, thickness measurement assembly 33, and inner diameter measurement assembly 34 are arranged sequentially from front to back. The finished workpiece is sequentially moved backward from the end where outer diameter measurement assembly 32 is located, driven by conveyor assembly 31, thereby sequentially measuring the outer diameter, thickness, and inner diameter of the finished workpiece. Furthermore, the end where outer diameter measurement assembly 32 is located is located within protective net 7, facilitating robot 4 to place the finished workpiece on inspection mechanism 3 for sequential inspection using each measurement assembly.

[0136] The function of the conveying assembly 31 is to move the finished workpiece placed on the measuring platform 31-1 to the outer diameter measuring assembly 32, the thickness measuring assembly 33 and the inner diameter measuring assembly 34 in sequence, and measure the corresponding parameters respectively. In order to realize the movement of the finished workpiece, the conveying assembly 31 includes a conveying screw 31-2, a conveying motor 31-3 connected to one end of the conveying screw 31-2, and a measuring platform 31-1 fixed on the nut of the conveying screw 31-2.

[0137] The conveying screw 31-2 is arranged on the inspection platform 35, and the conveying motor 31-3 is installed at the rear end of the conveying screw 31-2 to drive the conveying screw 31-2 to rotate. The finished workpiece is placed on the measurement platform 31-1, and the conveying motor 31-3 drives the conveying screw 31-2 to rotate, so that the measurement platform 31-1 can move linearly along the axis of the conveying screw 31-2.

[0138] Preferably, a dustproof cover 37 is installed on the conveying motor 31 - 3 to protect the conveying motor 31 - 3 .

[0139] Preferably, in order to guide the movement of the mobile platform, linear guide rails II31-4 are provided on both sides of the conveying screw 31-2, and a slider II31-5 is provided at the bottom of the measuring platform 31-1 to cooperate with the linear guide rails II31-4 to facilitate guidance when the measuring platform 31-1 moves.

[0140] In order to achieve clamping of the finished workpiece, the measuring platform 31 - 1 includes a table 31 - 6 and a pneumatic chuck 31 - 7 mounted on the table 31 - 6 .

[0141] After the finished workpiece is placed on the pneumatic chuck 31-7, the inner support claws in the pneumatic chuck 31-7 extend into the center hole of the finished workpiece, and then the inner support claws expand outward, thereby tightly adhering to the inner hole wall of the finished workpiece, thereby clamping and fixing the finished workpiece.

[0142] In order to ensure the measurement accuracy, an airtight detection plate 31 - 8 is installed in the inner hole of the pneumatic chuck 31 - 7 , and an airtight detection hole 31 - 9 is provided on the airtight detection plate 31 - 8 .

[0143] After the finished workpiece is placed on the measuring platform 31-1, if there are impurities such as iron filings remaining at the bottom of the finished workpiece, the finished workpiece will be tilted, which will directly affect the subsequent detection effect. Therefore, by setting the airtight detection hole 31-9, the placement of the finished workpiece can be effectively detected.

[0144] Airtightness detection hole 31-9 communicates with an air hole on the outer wall of pneumatic chuck 31-7, which in turn is connected to an air source via an air pipe, forming an airtightness detection path. If there are iron filings on the bottom of the finished workpiece, a gap will inevitably remain between them and airtightness detection plate 31-8, causing gas to leak from the top of airtightness detection hole 31-9, causing the air pressure in the airtightness detection path to drop. Conversely, if the air pressure in the airtightness detection path does not drop, it indicates that the finished workpiece has been properly placed and is free of impurities such as iron filings.

[0145] In order to measure the outer diameter of the finished workpiece, the outer diameter measuring components 32 are arranged on both sides of the conveying component 31 relative to each other.

[0146] Specifically, the outer diameter measuring assembly 32 includes two outer diameter measuring heads 32 - 1 that can be raised and lowered and moved inward or outward.

[0147] Specifically, the two outer diameter measuring heads 32 - 1 are arranged horizontally, and their measuring ends are arranged facing each other.

[0148] The conveying assembly 31 drives the finished workpiece to move between the two outer diameter measuring heads 32-1. The two outer diameter measuring heads 32-1 move toward each other and thus rest against the outer surface of the finished workpiece. The measuring ends of the outer diameter measuring heads 32-1 are compressed. At this time, the outer diameter of the finished workpiece can be calculated based on the compression amount.

[0149] Before measuring the finished workpiece, a standard part is selected as a measurement reference.

[0150] For example, if the outer diameter of a standard part is 100 mm, the inward compression stroke of the measuring tip of the outer diameter measuring head 32-1 is set to 3 mm when testing the standard part. When testing a finished workpiece, if the measuring tips of the two outer diameter measuring heads 32-1 retract inward by 3 mm, the workpiece's outer diameter is 100 mm. If the measuring tips of the two outer diameter measuring heads 32-1 retract inward by 2 mm, the finished workpiece's outer diameter is 98 mm, which is smaller than the outer diameter of the standard part. Conversely, if the measuring tips of the two outer diameter measuring heads 32-1 retract inward by 5 mm, the finished workpiece's outer diameter is 104 mm, which is larger than the outer diameter of the standard part. At this point, the finished workpiece's outer diameter is determined to be acceptable based on the tolerance range.

[0151] In order to realize the relative movement of the outer diameter measuring head 32-1, the outer diameter measuring assembly 32 further includes a transverse electric cylinder I 32-2. The outer diameter measuring head 32-1 is fixed on the slider of the transverse electric cylinder I 32-2 through a measuring bracket I 32-3.

[0152] Specifically, the measuring bracket I 32 - 3 is an L-shaped structure, and a side mounting opening is provided on the vertical plate thereof. The outer diameter measuring head 32 - 1 is installed in the side mounting opening and is locked by a screw passing through the side mounting opening.

[0153] The traverse drive of the outer diameter measuring head 32 - 1 is not limited to the traverse electric cylinder.

[0154] The lifting and lowering of the outer diameter measuring head 32-1 is to be able to measure the outer diameter of different positions of the same finished workpiece. In order to achieve this effect, the outer diameter measuring assembly 32 also includes an outer diameter measuring support frame 32-4, an outer diameter measuring motor 32-5 installed on the top of the outer diameter measuring support frame 32-4, and an outer diameter measuring screw 32-6 vertically arranged in the outer diameter measuring support frame 32-4 and connected to the outer diameter measuring motor 32-5. The transverse electric cylinder I 32-2 is connected to the nut of the outer diameter measuring screw 32-6 through the bracket 32-7.

[0155] A motor mounting frame II 32-8 is provided on the top of the outer diameter measuring support frame 32-4. The outer diameter measuring motor 32-5 is fixed on the motor mounting frame II 32-8 and drives the outer diameter measuring screw 32-6 connected thereto to rotate, thereby causing the bracket 32-7, the transverse electric cylinder I 32-2 and the outer diameter measuring head 32-1 to move up and down synchronously.

[0156] Preferably, two vertical plates II 32-9 arranged side by side are installed on the rear side of the outer diameter measuring support frame 32-4, and a linear guide rail III 32-10 is installed on the outer side of the vertical plate II 32-9. The bracket 32-7 is equipped with a slider III 32-11 that cooperates with the linear guide rail III 32-10, which can guide the lifting and lowering of the bracket 32-7.

[0157] The thickness measuring component 33 is used to measure the thickness of the finished workpiece. The finished workpiece is in the same position during outer diameter measurement and thickness measurement, which can effectively improve the measurement efficiency. Therefore, the thickness measuring component 33 is located on the rear side of the outer diameter measuring component 32 and above the conveying component 31.

[0158] In order to measure the thickness of the finished workpiece, the thickness measuring assembly 33 includes two thickness measuring heads 33 - 1 that can move toward or away from each other and can be raised and lowered synchronously.

[0159] Specifically, the thickness measuring head 33 - 1 is arranged vertically, with its measuring end facing downward.

[0160] The thickness measuring head 33-1 is moved laterally to achieve the measurement of different finished workpieces. In order to achieve this effect, the thickness measuring component 33 includes two oppositely arranged transverse electric cylinders II 33-2, and the thickness measuring head 33-1 is fixed on the slider of the transverse electric cylinder II 33-2 through the measuring bracket II 33-3.

[0161] The structure of the measuring bracket II 33-3 is the same as that of the measuring bracket I 32-3, except that the measuring bracket I 32-3 is placed horizontally, while the measuring bracket II 33-3 is placed vertically to facilitate the installation of measuring heads in different directions.

[0162] The traverse drive of the thickness measuring head 33-1 is not limited to the traverse electric cylinder.

[0163] After the finished workpiece is moved to the thickness measuring station, i.e., the outer diameter measuring station, the thickness measuring head 33-1 needs to be moved downward to measure the thickness of the finished workpiece. Therefore, the thickness measuring assembly 33 also includes a thickness measuring support frame 33-4, a thickness measuring cylinder 33-5 installed on the thickness measuring support frame 33-4 with the piston rod facing downward, and a lifting plate II 33-6 connected to the lower end of the piston rod of the thickness measuring cylinder 33-5. Two transverse electric cylinders II 33-2 are fixed on the lifting plate II 33-6.

[0164] The thickness measuring support frame 33-4 is a gate-shaped frame, with a mounting frame 34-6 and a cylinder mounting frame 34-6Ⅰ33-7 installed on the front side thereof. The thickness measuring cylinder 33-5 is installed on the mounting frame 34-6 and the cylinder mounting frame 34-6Ⅰ33-7, and the piston rod is set downward, and the lifting plate II 33-6 on the front side of the mounting frame 34-6 and the cylinder mounting frame 34-6Ⅰ33-7 is connected, and the two transverse electric cylinders II 33-2 are fixed on the front side of the lifting plate II 33-6, thereby driving the two thickness measuring heads 33-1 to rise and fall synchronously through the thickness measuring cylinder 33-5.

[0165] When the two thickness measuring heads 33-1 descend synchronously, the thickness measuring head 33-1 contacts the upper surface of the finished workpiece, and the measuring end of the thickness measuring head 33-1 is compressed. At this time, the thickness value of the product to be measured can be calculated based on the compression amount and the downward movement distance of the thickness measuring head 33-1.

[0166] The thickness is measured in the same way as the outer diameter. The fixed retraction stroke of the measuring end of the thickness measuring head 33-1 is also set based on the standard part. Then, the actual thickness of the measured finished workpiece is calculated based on the retraction stroke of the measuring end and the thickness value of the standard part during the actual measurement process, and compared with the thickness tolerance range to determine whether the thickness of the finished workpiece is qualified.

[0167] In order to limit the descent of the lifting plate II 33 - 6 , a limiting block 33 - 8 cooperating with the lifting plate II 33 - 6 is provided on one side of the thickness measurement support frame 33 - 4 .

[0168] The lifting drive of the thickness measuring head 33 - 1 is not limited to the air cylinder.

[0169] The inner diameter measuring assembly 34 is used to detect the inner diameter of the finished workpiece. The existing finished workpiece generally has a center hole, and the center hole has one or two different inner diameters (a step is provided in the center hole). Therefore, in this embodiment, three groups of inner diameter measuring assemblies 34 are provided, two of which are used to measure the inner diameter of the center hole, and one group is used as a backup for measuring the inner diameter of the center hole.

[0170] Therefore, at least one inner diameter measuring assembly 34 is provided and is located at the rear side of the thickness measuring assembly 33 and at one side of the conveying assembly 31 .

[0171] In order to measure the inner diameter, the inner diameter measuring assembly 34 includes an inner diameter measuring head 34 - 1 that can be raised and lowered.

[0172] In order to realize the lifting and lowering of the inner diameter measuring head 34-1, the inner diameter measuring assembly 34 also includes an inner diameter measuring support frame 34-2, an inner diameter measuring motor 34-3 installed on the top of the inner diameter measuring support frame 34-2, and an inner diameter measuring screw 34-4 arranged vertically in the inner diameter measuring support frame 34-2. The nut of the inner diameter measuring screw 34-4 is equipped with a mounting frame 34-6 through a connecting plate 34-5. The inner diameter measuring head 34-1 is installed on a fixed plate 34-7, and the fixed plate 34-7 is detachably mounted on the horizontal plate of the mounting frame 34-6.

[0173] A motor mounting frame III 34-8 is installed on the top of the inner diameter measuring support frame 34-2, and the inner diameter measuring motor 34-3 is fixed on the motor mounting frame III 34-8, which drives the rotation of the inner diameter measuring screw 34-4, and can realize the synchronous lifting and lowering of the mounting frame 34-6, the fixing plate 34-7 and the inner diameter measuring head 34-1.

[0174] Preferably, a pair of vertical plates III 34-9 are provided on the side of the inner diameter measuring support frame 34-2 facing the conveying assembly 31, and a linear slide rail (not shown in the figure) is provided on the outer side of the vertical plate III 34-9, and a linear slider that cooperates with the linear slide rail can be provided on the connecting plate 34-5 to achieve guidance when the mounting frame 34-6 is raised or lowered.

[0175] The fixing plate 34 - 7 is fixed to the horizontal plate of the mounting frame 34 - 6 by bolts, so as to facilitate the replacement of different inner diameter measuring heads 34 - 1 and realize the inner diameter measurement of workpieces of different specifications.

[0176] In order to measure the inner diameter of the finished workpiece, a measuring disc 34 - 10 mounted on a fixed plate 34 - 7 is provided at the bottom of the inner diameter measuring head 34 - 1 .

[0177] An inwardly retractable pin is provided on the outer ring surface of the measuring disk 34 - 10 , and a liftable wedge is provided inside the measuring disk 34 - 10 . The greater the inward retraction degree of the pin, the higher the height to which the wedge moves upward.

[0178] The inner diameter measuring head 34-1 is fixed on the fixed plate 34-7 so that the top of the wedge block in the measuring disk 34-10 is opposite to the measuring end of the inner diameter measuring head 34-1, so that the wedge block can push the inner diameter measuring head 34-1 upward to retract during measurement.

[0179] When measuring the inner diameter, the measuring disc 34-10 is placed in the inner hole to be measured. The inner hole wall pushes the pin to retract into the measuring disc 34-10, and then pushes the wedge block to rise. The rising wedge block pushes the inner diameter measuring head 34-1 upward to retract its measuring end, and the inner diameter of the measured inner hole can be calculated.

[0180] Specifically, there is a fixed functional relationship between the inward retraction distance of the pin on the measuring disk 34-10 and the rising stroke of the wedge block, that is, the retraction stroke of the measuring end of the inner diameter measuring head 34-1. The measuring method of the inner diameter is similar to that of the outer diameter. The fixed retraction stroke of the measuring end of the inner diameter measuring head 34-1 is also set based on the standard part. Then, the actual inner diameter of the measured finished workpiece is calculated based on the retraction stroke of the measuring end, the inner diameter value of the standard part and the corresponding functional relationship during the actual measurement process, and compared with the tolerance range of the inner diameter to determine whether the inner diameter of the finished workpiece is qualified.

[0181] In order to avoid affecting the installation of the measuring disk 34 - 10 , a U-shaped avoidance notch 34 - 11 is provided on the transverse plate of the mounting frame 34 - 6 , and the measuring disk 34 - 10 is located in the U-shaped avoidance notch 34 - 11 .

[0182] Some finished workpieces have inner rings with steps, and their thickness is different from that of their outer rings. In order to measure the thickness of the step part, the detection mechanism 3 includes an auxiliary thickness measuring component 38 arranged on one side of the conveying component 31, and the auxiliary thickness measuring component 38 includes an auxiliary thickness measuring head 38-1 that can be raised and lowered.

[0183] The thickness of the workpiece at the step to be measured is measured by raising and lowering the auxiliary thickness measuring head 38 - 1 .

[0184] Specifically, the auxiliary thickness measuring assembly 38 also includes an auxiliary thickness measuring support frame 38-2, and an auxiliary thickness measuring cylinder 38-3 installed on the top of the auxiliary thickness measuring support frame 38-2. The piston rod of the auxiliary thickness measuring cylinder 38-3 is set downward and connected to the lifting plate III 38-4 located in the auxiliary thickness measuring support frame 38-2. The outer surface of the lifting plate III 38-4 is installed with a mounting rod 38-6, and the auxiliary thickness measuring head 38-1 is installed on the mounting rod 38-6.

[0185] A cylinder mounting frame II 38-5 is installed on the side of the auxiliary thickness measuring support frame 38-2 facing the conveying component 31. The auxiliary thickness measuring cylinder 38-3 is fixed on the cylinder mounting frame II 38-5, and its piston rod is set downward and connected to the lifting plate III 38-4. The auxiliary thickness measuring cylinder 38-3 drives the lifting plate III 38-4 to rise and fall, thereby realizing the lifting and lowering of the auxiliary thickness measuring head 38-1.

[0186] A linear slide rail (not shown) is provided on the side of the cylinder mounting frame II 38-5 facing the conveying assembly 31, and a linear slider that cooperates with the linear slide rail is provided on the lifting plate III 38-4 to guide the up and down movement of the lifting plate III 38-4.

[0187] The measurement method of the auxiliary thickness measuring head 38 - 1 is the same as that of the thickness measuring head 33 - 1 , and both calculate the thickness of the workpiece at the measuring point by calculating the amount of its contraction and the downward movement distance of the auxiliary thickness measuring head 38 - 1 .

[0188] The turning processing system also includes a cleaning mechanism 8, which is located in front of the detection mechanism 3. When the finished workpiece is taken out of the turning machine tool II 6 by the robot 4, it is first placed in the cleaning mechanism 8 to remove the processing debris remaining on the surface of the finished workpiece, and then it is transferred to the detection mechanism 3 for measurement. During the blowing process, the robot 4 always keeps the finished workpiece in a clamping state and will not loosen the finished workpiece.

[0189] Specifically, the cleaning mechanism 8 includes a cleaning frame 81, a storage bucket 82 installed on the cleaning frame 81, and a plurality of blowing holes 83 are provided on the side wall of the storage bucket 82. The blowing holes 83 can be connected to an air source to blow air toward the finished workpiece placed in the storage bucket 82 to remove debris on its surface.

[0190] In addition, a dust collecting trough 84 is installed in the cleaning frame 81 at the bottom of the storage bucket 82 to facilitate the collection of debris dropped from the finished workpiece.

[0191] When processing the workpiece, the workpiece is placed on the stacking column 11-2, and the lifting plate 12-1 is used to lift the workpieces on each stacking column 11-2 one by one to the specified height, and the workpiece is moved to the turntable 14-2 using the material transfer claw 13-1. After the turntable 14-2 rotates the workpiece to the required angle, the robot 4 grabs the workpiece and places it in the turning machine tool Ⅰ5 for single-sided turning. After the single-sided turning is completed, a semi-finished workpiece is obtained. The robot 4 places the semi-finished workpiece on the flipping clamp Ⅰ23, and then transfers it to the flipping clamp Ⅱ24 to realize the flipping of the semi-finished workpiece. At this time, the robot 4 grabs the semi-finished workpiece from the flip clamp II 24 and transfers it to the turning machine tool II 6, and performs single-side turning on the semi-finished workpiece again to form a finished workpiece. The finished workpiece is taken out by the robot 4 and first placed in the storage bucket 82 to remove the debris on the surface of the finished workpiece. Then the robot 4 places the finished workpiece on the measuring platform 31-1 and measures the outer diameter, thickness, inner diameter and other parameters of the finished workpiece in turn. Unqualified products are screened out for subsequent turning and re-cutting, and qualified products can directly enter the next process.

[0192] The turning processing system provided by the present invention has a high degree of automation, which not only effectively improves the processing efficiency of the workpiece, but also ensures the processing quality.

[0193] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
