Description

Technical Field

[0001] The present invention relates to detection-related fields, and in particular to a detection device and a detection method for processing automobile transmission pulleys. Background Art

[0002] Pulleys are hub-type parts that are generally relatively large in size. Their manufacturing processes are generally based on casting and forging. Larger ones are generally cast, and are typically made of cast iron (which has better casting properties), rarely cast steel (which has poor casting properties). Smaller ones can be forged, and are made of steel. Pulleys are primarily used for long-distance power transmission, such as in small diesel engine outputs, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, some low-horsepower motorcycles, agricultural machinery, air compressors, speed reducers, reducers, generators, cotton gins, and more.

[0003] In the processing of pulleys, in order to ensure good quality, detection equipment is used. A pulley detection device is disclosed through searching, and the announcement number is: CN216978346U. The device has the following shortcomings: in order to reduce weight, existing pulleys are mostly hollowed out. This can reduce production costs while reducing the force required to drive the pulley. The hollowing design will form circumferentially equidistant reinforcement ribs on the pulley. The reinforcement ribs are similar to the support bars of a bicycle wheel. Whether the distribution of the reinforcement ribs is uniform directly affects the stability of the pulley during rotation. Secondly, defective products usually need to be reworked, and existing inspection equipment does not have a corresponding marking mechanism, including the above-mentioned patent, which makes the judgment of defective products during rework not direct enough.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 are within the scope of protection of the present invention.

[0037] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0038] For example 1, please refer to Figures 1 to 18 A testing device for automobile transmission pulley processing includes a testing box 1 and a partition 102 fixed to the testing box 1. The partition 102 divides the testing box 1 into an upper chamber and a lower chamber. The testing box 1 is hinged with two doors 101 for sealing the upper chamber and the lower chamber, including: Two No. 2 frames 201, each of which has at least four No. 2 guide rods 205 fixed on both sides of the bottom of the No. 2 frame 201. The No. 2 guide rods 205 pass through the partition 102 and are slidably connected thereto. The No. 2 guide rods 205 on both sides are fixed by a transmission plate 206. A No. 2 electric push rod 204 is fixed to the bottom of the partition 102, and the movable rod of the No. 2 electric push rod 204 is fixed to the transmission plate 206; A No. 1 guide rod 203 is fixed to each of the two No. 2 frames 201, and a No. 1 frame body 2 arranged in a U shape is slidably mounted on the two No. 1 guide rods 203, and a detection mechanism is mounted on the No. 1 frame body 2; Two flipping mechanisms are arranged opposite to each other, and the flipping mechanisms are installed on opposite sides of the two second frames 201.

[0039] In the embodiment of the present invention, a positioning member is further fixed on the partition 102. The top of the positioning member is conical and the bottom is circular. The diameter of the top of the positioning member is equal to the shaft hole of the pulley body 3. When performing the inspection, first open the door 101 of the upper chamber, then place the pulley body 3 in the inspection box 1, and place the shaft hole of the pulley body 3 on the positioning piece. Since the top of the positioning piece is conical, its diameter is smaller than the shaft hole diameter of the pulley body 3. When the pulley body 3 falls onto the partition 102, the pulley body 3 is positioned to the specified position by the positioning piece during its falling process. Of course, the present invention only provides a positioning means, and the same technical effect can also be achieved by other positioning structures. This application is not specifically limited. After the pulley body 3 completes the positioning work, the box door 101 is closed, and then the detection mechanism works to detect the distribution angle of the reinforcement ribs of the pulley body 3, and mark the unqualified positions for subsequent rework and adjustment. At the same time, the pulley body 3 is also tested for out-of-roundness; Among them, after completing the inspection of one side of the pulley body 3, the pulley body 3 needs to be flipped. At this time, the flipping mechanism works to complete the flipping of the pulley body 3. During this process, the No. 2 electric push rod 204 works. When the No. 2 electric push rod 204 works, it drives the transmission plate 206 to rise upright by retracting the movable rod, and then drives the No. 2 frame 201 and the No. 1 frame 2 and the collar components installed on the No. 1 frame 2 and the No. 2 frame 201 to rise through the No. 2 guide rod 205. The process on this side is to give enough space for the pulley body 3 to flip, and its specific function and coordination relationship are explained in the flipping mechanism.

[0040] The second embodiment is distinguished from the first embodiment in that the detection mechanism includes a supporting plate 5 rotatably mounted on the second frame 201 , one end of the supporting plate 5 is mounted with a roundness detection component, and the other end is mounted with a reinforcement rib detection component; The second frame 201 is also rotatably mounted with a driven disc 402 and a driving disc 401 that cooperate with each other. A driving gear is coaxially fixed to the rotating shaft of the driven disc 402, and the driving gear meshes with a driven gear 403 coaxially fixed to the rotating shaft of the carrier plate 5. A protective cover 404 for protecting the driving disk 401 , the driven disk 402 , the driven gear 403 and the driving gear is fixed on the second frame 201 . The motor 4 is fixed on the protective cover 404 . The output shaft of the motor 4 is coaxially fixed with the driving disk 401 .

[0041] In the embodiment of the present invention, when the motor 4 is working, the output shaft thereof drives the driving disk 401 to rotate. When the driving disk 401 rotates one circle, the driven disk 402 is driven to rotate a certain angle. When the driven disk 402 rotates, the engagement between the driving gear and the driven gear 403 drives the carrier plate 5 to rotate. Among them, the driving disk 401 and the driven disk 402 are the application of the Maltese cross movement in the prior art, and their main function is to transmit at equal angles and have a self-locking effect. The driving gear is a small gear and the driven gear 403 is a large gear, so as to achieve the effect of deceleration and torque increase, and ultimately achieve that the carrying plate 5 rotates 3° when the driving disk 401 rotates one circle, and has a self-locking effect when not rotating, avoiding angle changes when the out-of-round detection component and the reinforcement rib detection component are working; It should also be noted that the motor 4 in the present invention is a high-precision servo motor. Of course, a stepper motor or a DC motor may also be used. The present invention does not make any specific restrictions as long as the driving requirements are met.

[0042] The reinforcement rib detection assembly includes two movable grooves 507 provided at one end of the carrier plate 5. A No. 1 detection head 508 is slidably mounted in each of the two movable grooves 507. The two No. 1 detection heads 508 are also slidably connected via a synchronous transmission rod 509. The spacing between the two movable grooves 507 gradually increases. A third gear 5014 is rotatably mounted on the synchronous transmission rod 509 between the two first detection heads 508; A motor bracket 5011 is slidably mounted on the carrier plate 5, a second motor 5012 is fixed to the motor bracket 5011, and a second gear 5013 is rotatably mounted on the motor bracket 5011. The output shaft of the second motor 5012 is connected to the second gear 5013 via a transmission chain, and the second gear 5013 is meshed with the third gear 5014. The motor bracket 5011 is rotatably connected to the third gear 5014 or the synchronous transmission rod 509 via a connecting plate 5010 fixed thereto. A rack 5015 is fixed on the carrier plate 5 , and the rack 5015 is meshed with the third gear 5014 ; Wherein, a through slot is provided at the bottom of the motor bracket 5011; The carrier plate 5 is also provided with a feedback component that cooperates with the first detection head 508 .

[0043] In this embodiment of the present invention, when the second motor 5012 is operating, its output shaft drives the second gear 5013 to rotate via a transmission chain. The meshing of the second gear 5013 with the third gear 5014 drives the third gear 5014 to rotate. As the third gear 5014 rotates, it meshes with the rack 5015 to move horizontally. The horizontal movement of the third gear 5014 drives the two first detection heads 508 to move synchronously via the synchronous transmission rod 509. Simultaneously, the motor bracket 5011 is driven to follow the movement via the connecting plate 5010. The two No. 1 detection heads 508 gradually move in opposite directions as the distance between the two movable grooves 507 increases. For example, the distance between the two reinforcing ribs of the pulley body 3 decreases toward the center of the pulley body 3. The movement trajectory of the No. 1 detection head 508 in the present invention is consistent with the characteristics of the reinforcing ribs of the pulley body 3, thereby detecting whether the distance between the two reinforcing ribs of the pulley body 3 is abnormal. Among them, the two No. 1 detection heads 508 move from the starting end of the stroke to the end of the stroke for one detection work, and move from the end of the stroke to the starting end of the stroke for another detection work. In addition, the No. 2 motor 5012 in the present invention can be a motor with positive and negative outputs, and the detection efficiency is improved by performing detection through back and forth motion.

[0044] The feedback assembly includes a mounting groove 5026 provided on a side of the carrier plate 5 away from the out-of-round detection assembly, two No. 3 guide rods 5021 are fixed in the mounting groove 5026, a slide is slidably mounted on the No. 3 guide rod 5021, and two No. 2 motors 5012 are each sleeved with a No. 1 spring 5022, one end of the No. 1 spring 5022 is fixed to the slide, and the other end is fixed to the inner wall of the mounting groove 5026, a marking pen 5020 is slidably mounted on the slide, and a No. 2 spring 5023 is further sleeved on the slide, one end of the No. 2 spring 5023 is fixed to the marking pen 5020, and the other end is fixed to the slide; The marking pen 5020 is connected to a driving member installed on the supporting plate 5 , and communication is established between the driving member and the movable slot 507 .

[0045] In the embodiment of the present invention, the marking pen 5020 is driven by a driving member to move vertically downward or horizontally. The vertical downward movement of the marking pen 5020 will leave a dot mark at the corresponding position of the pulley body 3, while the horizontal movement will leave a line at the corresponding position. Among them, the point corresponds to the current position that has completed the test and is qualified, and the line corresponds to the current position that has completed the test and is unqualified; It should also be noted that the force required to compress the No. 2 spring 5023 is greater than that of the No. 1 spring 5022, and the tip of the marking pen 5020 can be elastically retracted and expanded. Elastic expansion and contraction means that when the tip is subjected to force, it retracts and compresses the internal elastic component, and when no force is applied, the elastic potential energy of the elastic component is released to drive the tip to reset.

[0046] The driving member includes a force-bearing block 5024 fixed to one side of the marking pen 5020, and the force-bearing block 5024 is provided with an inclined portion 5025; The force block 5024 is slidably mounted on the side away from the marking pen 5020 with a push plate 5017, and the push plate 5017 is rotatably mounted on the side toward the marking pen 5020 with a roller 5019 that cooperates with the force block 5024 and the inclined portion 5025; A fourth electric push rod 5016 is also fixed on the supporting plate 5, and the movable rod of the fourth electric push rod 5016 is slidably connected to the push plate 5017. An electromagnet 5018 is also fixed on the supporting plate 5, and the movable rod of the electromagnet 5018 is slidably connected to the push plate 5017.

[0047] In the embodiment of the present invention, when the movable slot 507 completes the detection, the fourth electric push rod 5016 is driven to work. When the fourth electric push rod 5016 is working, it pushes the push plate 5017 to move toward the marking pen 5020. During this process, the movement of the push plate 5017 and the roller 5019 does not contact the force block 5024. When the movement reaches the end of the stroke, the push plate 5017 is driven to descend by the electromagnet 5018. This process leaves a mark on the pulley body 3. When the test result is unqualified, the push plate 5017 is driven downward by the electromagnet 5018, so that the push plate 5017 and the roller 5019 cooperate with the inclined portion 5025 to drive the marking pen 5020 downward during the movement, and the stroke of the push plate 5017 is increased. When the tip of the marking pen 5020 contacts the pulley body 3 to leave a point mark, the push plate 5017 moves horizontally to leave a line mark on the pulley body 3. Among them, the functions of the No. 2 spring 5023 and the No. 1 spring 5022 are to provide the power required for the marker pen 5020 to reset after movement.

[0048] The out-of-round detection assembly includes a mounting plate 501 slidably mounted on an end of the carrier plate 5 away from the reinforcement rib detection assembly, and a plurality of second detection heads 5027 are fixed on the side of the mounting plate 501 facing the reinforcement rib detection assembly; A slider 505 is slidably mounted on the carrier plate 5, and a No. 2 guide wheel 503 is also fixed on the carrier plate 5. The movable rod of the No. 2 guide wheel 503 is fixed to the slider 505, and the slider 505 is connected to the mounting plate 501 through a traction rope 504. The No. 2 guide wheel 503 and the No. 1 guide wheel 502 for limiting the No. 2 guide wheel 503 are rotatably mounted on the carrier plate 5.

[0049] In the embodiment of the present invention, the roundness of the pulley body 3 is detected by the second detection head 5027. Since the supporting plate 5 rotates equidistantly, the mounting plate 501 is driven to rotate around the center of the supporting plate 5, thereby realizing the detection work. Among them, since the pulley body 3 involves flipping during the detection process, in order to avoid the flipping of the pulley body 3 from interfering with the mounting plate 501, the No. 3 electric push rod 506 is driven to work, and when the No. 3 electric push rod 506 is working, it pushes the slider 505 to move, so as to pull the traction rope 504 through the slider 505, and then the mounting plate 501 is erected and raised under the pulling of the traction rope 504.

[0050] Embodiment 3, the distinguishing feature from embodiment 1 and / or embodiment 2 is that the flipping mechanism includes a rectangular groove opened on two No. 2 frames 201, and a limiting member 602 is slidably installed in the rectangular groove, and a transmission rod 6 is fixed on the opposite side of the two limiting members 602, and a transmission cylinder 601 is sleeved on the transmission rod 6 and slidably cooperated with it, and the transmission rod 6 is connected to the relatively moving part installed on the No. 2 frame 201, and the transmission rod 6 is connected to the rotating part installed on the No. 2 frame 201.

[0051] In the embodiment of the present invention, when the relative moving member is working, it drives the two transmission rods 6 and the limiting member 602 to move relative to each other, so as to clamp the pulley body 3; When the rotating member is working, the transmission rod 6 and the transmission cylinder 601 are driven to rotate, so that the rotation of the transmission rod 6 drives the limiting member 602 and the pulley body 3 to rotate; Among them, a plurality of transmission bars are fixed at equal intervals on the circumference of the transmission rod 6, and the transmission bars slide in cooperation with the transmission grooves provided on the inner wall of the transmission cylinder 601, so that the transmission rod 6 and the transmission cylinder 601 rotate synchronously and can slide axially.

[0052] The relative motion member includes an L-shaped rack plate 603 slidably mounted on the two second frames 201, the L-shaped rack plate 603 being rotatably connected to the transmission rod 6, and a fourth gear 609 rotatably mounted on the second frame 201 and meshing with the L-shaped rack plate 603; The L-shaped rack plate 603 is provided with a through slot 604, in which an active rack plate meshing with the fourth gear 609 is installed. The active rack plate is fixed to the first frame 2; A first electric push rod 202 is fixed to the side of the second frame 201 away from the fourth gear 609 , and a movable rod of the first electric push rod 202 is fixed to the first frame 2 .

[0053] In the embodiment of the present invention, when the No. 1 electric push rod 202 is working, it drives the No. 1 frame 2 to rise vertically. The vertical rise of the No. 1 frame 2 is to prevent the pulley body 3 from interfering with the supporting plate 5 and the No. 1 frame 2 when turning over. When the No. 1 frame 2 rises, the active rack plate is driven to rise with it, so that the No. 4 gear 609 is driven to rotate by the rising active rack plate. When the two synchronous transmission rods 509 rotate, the two L-shaped rack plates 603 are driven to move relative to each other through engagement with the two L-shaped rack plates 603, thereby driving the two transmission rods 6 to move relative to each other. Among them, the above-mentioned No. 2 electric push rod 204 drives the No. 2 frame 201 to rise after completing the clamping of the pulley body 3, carrying the pulley body 3 to rise, so that the pulley body 3 does not interfere with the partition 102 when turning over. This process drives the rotating part to work.

[0054] The rotating part includes a worm wheel 608 coaxially fixed on the transmission cylinder 601, and a worm 607 that cooperates with it is rotatably installed on one side of the worm wheel 608. A ratchet 606 is coaxially fixed on one end of the worm 607, and the ratchet 606 is unidirectionally matched with a pawl plate 605 fixed on the partition 102.

[0055] In the embodiment of the present invention, when the second frame 201 is vertically ascended, the ratchet 606 and the pawl plate 605 cooperate to drive the ratchet 606 and the worm 607 to rotate, so that when the worm 607 rotates, the worm wheel 608 and the transmission cylinder 601 are driven to rotate, thereby driving the pulley body 3 to rotate; After the pulley body 3 rotates 180°, it descends. During the descending process, the ratchet wheel 606 does not have a transmission relationship with the pawl plate 605, and thus the pulley body 3 does not rotate.

[0056] The present invention also provides a detection method for processing automobile transmission pulleys, which uses the detection device for processing automobile transmission pulleys, and is characterized by comprising the following steps: Step 1: Open the door 101 and place the pulley body 3 at a designated position, then close the door 101; Step 2: Use a detection mechanism to detect the reinforcement and roundness of the pulley body 3; Step three: flip the pulley body 3 through the flipping mechanism and inspect the other side of the pulley body 3.
