Description

Technical Field

[0001] The present invention relates to the field of workpiece detection devices, and specifically to a detection device for detecting the aperture of a motor punching sheet. Background Technique

[0002] The aperture processing of workpieces with through holes is usually completed by milling machines. During drilling operations, the size of the workpiece aperture is greatly affected by the drill bit. For example, if the drill bit is damaged due to excessive wear or impact during use, or if the drill bit angle is not selected properly, the aperture will be too large during drilling. At the same time, if the drilling speed is too fast, the aperture will also be too large.

[0003] The motor punching sheet, as an important component of the motor, has strict regulations on the size of its aperture. Currently, for the measurement of the hole diameter, there are measurement methods such as direct measurement, indirect measurement, and comprehensive measurement. For the high matching degree requirement between the core hole of the punching sheet and the punch, relevant measurements are generally carried out using a coordinate measuring machine. However, the limitations of coordinate measurement are relatively high. It not only has high requirements for the surface quality of parts, but also has a long scanning time, restricting its application in some industrial production assembly lines. After the detection, the motor punching sheets still need to be sorted manually, with low efficiency. Summary of the Invention

[0020] By setting up a transport component, a detection component and a lifting component, and under the action of the driving component, the lifting component is first driven to drive the detection component to gradually approach the motor punching body placed on the conveyor belt, and then the detection component is driven to detect the motor punching body, and the detection device is driven to perform subsequent actions according to the result fed back to the control center by the sensor on the arc plate in the detection component;

[0021] If the aperture of the motor punching body is qualified, the detection component will automatically follow the lifting component to return to the initial height, and the conveyor belt will transport the qualified motor punching body to the collection box outside the base;

[0022] If the aperture of the motor punching body is unqualified, the detection component will drive the unqualified motor punching body to follow the lifting component to restore to the initial height, and then slide it into the receiving box on the control box, so as to realize the sorting of the motor punching body;

[0037] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions.

[0038] Please refer to Figures 1 - 12 , in the embodiment of the present invention, a detection device for detecting the aperture of a motor lamination includes: a base 1, a control box 201 and a longitudinal member 202 are installed on the left and right sides of the base 1, an installation bracket 3 is arranged between the control box 201 and the longitudinal member 202, and a fixed box 301 is installed on the installation bracket 3;

[0039] Specifically, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 12 , a control center 101 and a display 102 are provided on the base 1, the display 102 real-time feeds back the detection result of the motor lamination aperture detection device on the motor lamination body 103, and the detected result will be fed back to the control center 101, so as to drive the detection device to make a reasonable reaction, and then screen out qualified products.

[0040] A lifting assembly is arranged on the control box 201, and the lifting assembly includes a reciprocating member slidably arranged on the control box 201;

[0041] The reciprocating member includes a slide plate 14 slidably arranged on the control box 201, a slide groove 1401 is formed on one side of the slide plate 14 facing the control box 201, and the slide plate 14 is connected to the longitudinal member 202 through a lifting plate 7;

[0042] The lifting assembly further includes two sets of rotating rods 19 arranged along the longitudinal direction of the control box 201. A belt 5 is arranged between the two sets of rotating rods 19. A protrusion 501 is fixedly arranged on the belt 5, and the protrusion 501 is slidably arranged in the chute 1401;

[0043] Specifically, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , on the side of the above-mentioned sliding plate 14 facing the control box 201, two sets of clamping rods 1402 are fixedly arranged at equal intervals along its length direction. The clamping rods 1402 are slidably arranged in two sets of clamping grooves 203 opened on the control box 201. Due to the cooperation between the clamping rods 1402 and the clamping grooves 203, the sliding plate 14 can only drive the lifting plate 7 to slide along the longitudinal direction of the control box 201;

[0044] In detail, in the initial state, the lifting plate 7 is far from the base 1. When the rotating rods 19 rotate continuously in the same direction, the belt 5 arranged on the rotating rods 19 will drive the protrusion 501 to rotate continuously in the same direction. And when the belt 5 rotates one week, the protrusion 501 will slide in the chute 1401, and at the same time drive the sliding plate 14 and the lifting plate 7 to make a reciprocating slide along the clamping groove 203 once.

[0045] Furthermore, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , a detection device for detecting the aperture of a motor punching sheet further includes: a detection assembly arranged in the fixed box 301, including two sets of sliding members symmetrically slidably arranged in the fixed box 301, and the sliding members are connected to the reciprocating member through a lifting member;

[0046] The sliding member includes a sliding rod 10. A sleeve 1001 is fixedly arranged at one end of the sliding rod 10 away from the lifting plate 7. The sleeve 1001 is slidably connected to a guide rod 8 fixedly arranged in the fixed box 301. A first spring 13 is also slidably arranged on the guide rod 8. One end of the first spring 13 abuts against the sleeve 1001, and the other end abuts against the fixed box 301;

[0047] Preferably, please refer to Figure 3 , Figure 4 , Figure 5, In the initial state, the first spring 13 is in a compressed state. At this time, the compressed first spring 13 will push the two groups of sliding rods 10 closer to each other, so that the distance between the two groups of sliding rods 10 is the shortest, so that when the lifting member follows the lifting plate 7 to approach the base 1, the lifting member provided on the sliding rod 10 can be placed within the aperture of the motor punching plate body 103, thereby facilitating the subsequent detection process.

[0048] The lifting member includes a lifting rod 11 slidably arranged on the lifting plate 7. A socket ring 1101 is fixedly arranged at one end of the lifting rod 11 away from the lifting plate 7. The socket ring 1101 is slidably connected with the sliding rod 10. The two lifting rods 11 are close to the lifting plate 7, and insertion rods 17 are fixedly arranged on the sides facing the control box 201 and the longitudinal member 202 respectively. An arc-shaped plate 16 is elastically slidably arranged on the insertion rod 17;

[0049] Preferably, please refer to Figure 7 , Figure 8 , The above-mentioned lifting rod 11 is slidably arranged in the through groove 701 opened on the lifting plate 7. Specifically, two groups of retaining plates 1102 are fixedly arranged on the lifting rod 11. The distance between the two groups of retaining plates 1102 is equal to the thickness of the lifting plate 7. Through the cooperation between the retaining plates 1102 and the lifting plate 7, the lifting rod 11 can follow the lifting plate 7 to rise and fall, and at the same time, the lifting rod 11 can only slide along the length direction of the lifting plate 7;

[0050] Specifically, please refer to Figure 8 , The above-mentioned arc-shaped plate 16 is provided with two groups of insertion slots 1601 along its length direction. One end of the insertion rod 17 away from the lifting rod 11 is slidably arranged in the insertion slot 1601, and a second spring 18 is slidably arranged on the insertion rod 17. One end of the second spring 18 abuts against the arc-shaped plate 16, and the other end abuts against the lifting rod 11. In the initial state, the second spring 18 is in a compressed state, and the compressed second spring 18 will push the arc-shaped plate 16 away from the lifting rod 11.

[0051] The detection assembly further includes a driving structure. The driving structure includes a turntable 9 rotatably installed on the fixed box 301. Two groups of pulleys 901 are symmetrically installed on one side of the turntable 9 facing the guide rod 8. The two groups of pulleys 901 are respectively matched with the sliding rod 10;

[0052] Specifically, please refer to Figure 3 , Figure 4 , Figure 5, in combination with the above, with the cooperation of the first spring 13, the above two groups of pulleys 901 will always be in contact with the two groups of sliding rods 10. In the initial state, that is, when the two groups of sliding rods 10 approach each other, the connection line between the two groups of pulleys 901 is perpendicular to the horizontal ground. And when the lifting rod 11 follows the lifting plate 7 and approaches the base 1, the turntable 9 will rotate continuously in the same direction. At this time, the pulley 901 installed on the turntable 9 will rotate synchronously with the turntable 9, and then drive the two groups of sliding rods 10 to move away from each other, so that the arc plate 16 arranged on the lifting rod 11 gradually approaches the motor punching sheet body 103 placed on the base 1. Until after the arc plate 16 contacts the motor punching sheet body 103, the continuously rotating turntable 9 will cause the arc plate 16 to squeeze the second spring 18 inward. At this time, the squeezed second spring 18 will push the arc plate 16 in the reverse direction, so that the arc plate 16 squeezes the motor punching sheet body 103. In particular, a sensor (not shown in the figure) is arranged on the surface of the arc plate 16 in contact with the motor punching sheet body 103, and the sensor is electrically connected to the display 102. It should be added that the distance between the two groups of pulleys 901 is greater than the aperture of the qualified motor punching sheet body 103. Therefore, when the aperture of the motor punching sheet body 103 placed on the base 1 is standard, the retraction distance of the arc plate 16 towards the lifting rod 11 must be constant. At this time, the retracted arc plate 16 will trigger the sensor arranged on the arc plate 16, and then the triggered sensor will feedback the standard value to the display 102. The control center 101 that receives the feedback value will drive the turntable 9 to reverse (at this time, the rotation angle of the turntable 9 is less than 180 degrees). After the two groups of sliding rods 10 return to the initial position, the lifting assembly will start to act and drive the lifting rod 11 back to the initial position;

[0053] On the contrary, when the aperture of the motor punching sheet body 103 placed on the base 1 is too large, when the mutually separated lifting rods 11 make the arc plate 16 contact the motor punching sheet body 103, the retraction amount of the arc plate 16 will not trigger the sensor. Therefore, the turntable 9 will continue to rotate in the same direction until the connection line between the two groups of pulleys 901 is parallel to the horizontal ground, and then the turntable 9 stops rotating. At this time, the reaction force of the compressed second spring 18 on the arc plate 16 is sufficient to enable the two arc plates 16 to clamp the motor punching sheet body 103, so that when the subsequent lifting rod 11 follows the lifting plate 7 to rise, the unqualified motor punching sheet body 103 with too large aperture will follow the arc plate 16 to move away from the base 1, and then screen out the motor punching sheet body 103 with unqualified aperture.

[0054] Furthermore, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 11 、 Figure 12, A detection device for detecting the aperture of a motor punching sheet further includes: a transportation component disposed within the base 1 for transporting the motor punching sheet body 103;

[0055] The transportation component includes a conveyor belt 26 rotatably installed on the base 1. A plurality of placement grooves 2601 are equidistantly arranged on the conveyor belt 26, and the placement grooves 2601 are used for placing the motor punching sheet body 103;

[0056] Specifically, the above-mentioned conveyor belt 26 is connected to the rotating rod 19, that is, when the rotating rod 19 rotates, it can drive the conveyor belt 26 to rotate synchronously. And the above-mentioned placement grooves 2601 are slightly concave circular grooves for placing the motor punching sheet body 103. Under the restriction of the placement grooves 2601, when the conveyor belt 26 stops moving, the center of the motor punching sheet body 103 on the conveyor belt 26 coincides with the center connected by the two sliding rods 10, so as to facilitate the subsequent detection of the motor punching sheet body 103 by the lifting member.

[0057] Furthermore, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 10 、 Figure 11 、 Figure 12 , A detection device for detecting the aperture of a motor punching sheet further includes: a driving component disposed within the control box 201, connected to the lifting component and the detection component, capable of driving the lifting member and the detection component to move alternately. And when the lifting component operates, the reciprocating member will drive the lifting member to descend in the longitudinal direction relative to the control box 201. Subsequently, the detection component will drive the two lifting members to perform aperture detection on the motor punching sheet body 103 placed on the transportation component;

[0058] The driving component includes a driving wheel, a first driven wheel, and a second driven wheel rotatably installed within the control box 201. A first transmission wheel 22 is coaxially and fixedly arranged on the first driven wheel. The first transmission wheel 22 is connected to a linkage rod 24 rotatably installed on the fixed box 301 through a transmission belt. The linkage rod 24 is connected to the turntable 9 through a bevel gear set 12 and a linkage belt. A second transmission wheel 25 is coaxially and fixedly arranged on the second driven wheel. The second transmission wheel 25 is connected to the rotating rod 19 through a second transmission belt;

[0059] Specifically, the above-mentioned bevel gear set 12 includes a first bevel gear and a second bevel gear. The first bevel gear is rotatably installed on the mounting bracket 3, and the second bevel gear is rotatably installed within the fixed box 301 and is connected to the rotating shaft of the turntable 9 through a linkage belt;

[0060] For details, please refer toFigure 2 , Figure 3 , Figure 10 The first driven wheel and the second driven wheel are provided with four groups of grooves equidistantly arranged along their circumferential directions, and the rotating shaft of the driving wheel is coaxially fixedly connected with the output shaft of the servo motor fixedly installed on the control box 201. In particular, a trigger rod is fixedly arranged on the side of the driving wheel away from the servo motor. When the driving wheel is driven by the servo motor to rotate one circle, the trigger rod fixed on the driving wheel will successively engage with the grooves on the second driven wheel and the first driven wheel, thereby driving the second driven wheel and the first driven wheel to rotate a quarter of a circle; it should be supplemented that the radius of the second transmission wheel 25 is a multiple of the radius of the rotating rod 19. When the second transmission wheel 25 follows the second driven wheel to rotate a quarter of a circle When the first driven wheel 22 rotates a quarter of a circle following the first driven wheel, it can drive the linkage rod 24 to rotate half a circle. Subsequently, under the connection of the bevel gear set 12 and the linkage belt, the turntable 9 can be driven to rotate half a circle. At this time, the pulley 901 arranged on the turntable 9 cooperates with the first spring 13, which will drive the two groups of slide bars 10 to drive the two groups of lifting rods 11 to move away from or approach each other, thereby approaching or moving away from the motor punch body 103.

[0061] Furthermore, a receiving assembly is provided between the control box 201 and the longitudinal member 202, and the receiving assembly includes a receiving box 4 slidably provided between the control box 201 and the longitudinal member 202, a guide plate 6 is fixedly provided on the receiving box 4, an engaging groove is provided on the guide plate 6, a cross bar 1501 fixedly connected to the lifting plate 7 is slidably provided in the engaging groove, and when the lifting plate 7 is lifted or lowered, the cross bar 1501 cooperates with the engaging groove to drive the receiving box 4 to slide relative to the base 1;

[0062] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 11 , the receiving box 4 is slidably connected with the slide rail 401 fixedly arranged on the control box 201 and the longitudinal member 202, and the above-mentioned embedded groove body includes a vertical groove 601 and an inclined groove 602, and the above-mentioned cross bar 1501 is fixedly connected with the mounting plate 15 fixedly arranged on the lifting plate 7. In the initial state, when the two sets of sliding bars 10 close to each other are away from the base 1, the receiving box 4 is located directly above the base 1, and the cross bar 1501 is located at the end of the travel of the inclined groove 602. In combination with the above, the servo motor will drive the driving wheel to rotate clockwise (combined with Figure 3), the clockwise rotating driving wheel will first enter the meshing transmission state with the second driven wheel, thereby driving the second driven wheel, the belt 5 and the conveyor belt 26 to rotate counterclockwise. At this time, with the cooperation of the protruding column 501 and the sliding plate 14, the lifting plate 7 will drive the lifting rod 11 to gradually approach the conveyor belt 26. Until the driving wheel is separated from the second driven wheel, the lifting plate 7 descends to the lowest position, and the conveyor belt 26 stops moving. At this time, the arc-shaped plates 16 arranged on the two lifting rods 11 are just placed in the holes opened on the motor punching body 103. And during this process, the contact extrusion generated between the cross bar 1501 following the descent of the lifting plate 7 and the wall of the inclined groove 602 will force the receiving box 4 to slide along the slide rail 401, gradually move away from directly above the base 1 until the cross bar 1501 moves to the end of the stroke of the inclined groove 602 and combines with the vertical groove 601. The projection of the receiving box 4 on the base 1 does not overlap with the motor punching body 103 placed on the conveyor belt 26, and the lifting rod 11 still remains above the receiving box 4. As the lifting plate 7 continues to descend, the lifting rod 11 will cross the receiving box 4 and combine with the conveyor belt 26, and the cross bar 1501 will slide in the vertical groove 601 to keep the position of the receiving box 4 unchanged;

[0063] Subsequently, the driving wheel will enter the meshing state with the first driven wheel. At this time, under the connection of the bevel gear set 12 and the linkage belt, the turntable 9 starts to rotate counterclockwise. And during the rotation of the turntable 9, the pulley 901 arranged on the turntable 9 will drive the two sliding rods 10 to move away from each other, and then the two arc-shaped plates 16 will gradually come into contact with the motor punching body 103:

[0064] When the sensor arranged on the arc-shaped plate 16 is triggered, after the control center 101 receives the signal feedback from the display 102, it will drive the servo motor to reverse. At this time, the driving wheel will drive the first driven wheel to rotate clockwise. At this time, with the cooperation of the first spring 13, the two sliding rods 10 will gradually approach until they return to the initial position. Then the driving wheel will enter the meshing transmission state with the second driven wheel, and then drive the lifting plate 7 to rise, and then drive the lifting rod 11 back to the initial position. At the same time, the conveyor belt 26 will rotate clockwise to transport the qualified motor punching body 103 to the collection box placed outside the base 1. The receiving box 4 will also remain stationary under the cooperation of the cross bar 1501 and the fitting groove body until the lower end of the lifting rod 11 is higher than the receiving box 4, and then the cross bar 1501 cooperates with the inclined groove 602 to restore the receiving box 4 to the initial position;

[0065] When the sensor on the arc-shaped plate 16 is not triggered, the driving wheel will continuously maintain the driving state of meshing with the first driven wheel, driving the turntable 9 to rotate 180 degrees. At this time, with the cooperation of the second spring 18, the two groups of arc-shaped plates 16 can clamp the motor lamination body 103. Subsequently, when the driving wheel and the second driven wheel enter the meshing transmission state, they will drive the lifting rod 11 and the unqualified motor lamination body 103 to leave the conveyor belt 26 together. Until the lifting plate 7 returns to the initial height, the driving wheel will separate from the second driven wheel and then combine with the first driven wheel to drive the turntable 9 to continue rotating 180 degrees. At this time, the two groups of slide rods 10 will approach each other under the action of the first spring 13, so that the motor lamination body 103 that rose with the lifting rod 11 before will fall into the receiving box 4 under the influence of gravity, thus achieving the purpose of collecting the unqualified motor lamination body 103;

[0066] Then, by repeating the above process, the aperture detection of the next group of motor lamination bodies 103 can be carried out. Compared with the coordinate measuring instrument, it has lower limitations and is not restricted by the surface quality of the parts. At the same time, during the detection process, the sorting work of the motor lamination body 103 can be completed synchronously, with higher efficiency.

[0067] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
