Description

Technical Field

[0001] This invention relates to the field of testing, specifically a testing device and method for processing automotive transmission pulleys. Background Technology

[0002] Belt pulleys, belonging to the category of disc-hub parts, are generally relatively large in size. Manufacturing processes primarily involve casting and forging. Larger pulleys are typically designed using casting, usually with cast iron (due to its superior casting properties), and rarely with cast steel (due to its poor casting properties). Smaller pulleys can be designed using forging, with steel as the material. Belt pulleys are mainly used for long-distance power transmission, such as in small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, power transmission in some low-horsepower motorcycles, power transmission in agricultural machinery, air compressors, reducers, speed reducers, generators, cotton gins, etc.

[0003] In the processing of pulleys, testing equipment is used to ensure that the products are of good quality. A pulley testing device has been disclosed in the search results (announcement number: CN216978346U). The shortcomings of this device are that existing pulleys are designed with a lot of hollowing out in order to reduce weight. This device can reduce production costs and reduce the force required to drive the pulley to rotate. The hollowing out design will form circumferentially equidistant reinforcing ribs on the pulley. These reinforcing ribs are similar to the support bars of a bicycle wheel. The uniformity of the distribution of these reinforcing ribs directly affects the stability of the pulley during rotation.

[0004] Secondly, defective products usually require rework, and existing testing equipment does not have a corresponding marking mechanism, including the aforementioned patent, which makes it difficult to directly identify defective products during rework. Summary of the Invention

Detailed Implementation

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0063] Example 1, please refer to Figures 1 to 18 A testing device for processing automotive transmission pulleys includes a testing box 1 and a partition 102 fixed inside the testing box 1. The partition 102 divides the testing box 1 into an upper cavity and a lower cavity. Two doors 101 are hinged to the testing box 1 to seal the upper and lower cavities.

[0064] Two second frames 201 are provided. At least four second guide rods 205 are fixed on both sides of the bottom of each second frame 201. The second guide rods 205 pass through the partition 102 and are slidably connected to it. The second guide rods 205 on both sides are fixed together by a transmission plate 206. A second electric push rod 204 is fixed at the bottom of the partition 102. The movable rod of the second electric push rod 204 is fixed to the transmission plate 206.

[0065] Each of the two No. 2 frames 201 is fixed with a No. 1 guide rod 203, and a No. 1 frame body 2 arranged in a U-shape is slidably installed on the two No. 1 guide rods 203. A detection mechanism is installed on the No. 1 frame body 2.

[0066] Two flipping mechanisms are arranged opposite each other, and the flipping mechanisms are installed on opposite sides of the two No. 2 frames 201.

[0067] In this embodiment of the invention, a positioning member is also 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.

[0068] When conducting the testing, first open the upper chamber door 101, then place the pulley body 3 inside the testing chamber 1, and position the shaft hole of the pulley body 3 on the positioning member. Since the top of the positioning member is tapered and its diameter is smaller than the diameter of the shaft hole of the pulley body 3, when the pulley body 3 falls onto the partition 102, its falling process positions the pulley body 3 to the designated position through the positioning member. Of course, this invention only provides a positioning method, and the same technical effect can also be achieved through other positioning structures. This application does not make specific limitations.

[0069] After the pulley body 3 completes the positioning work, the box door 101 is closed. Then the detection mechanism works to detect the distribution angle of the reinforcing ribs of the pulley body 3 and mark the unqualified positions for subsequent rework and adjustment. At the same time, it also detects whether the pulley body 3 is out of round.

[0070] 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 is activated to complete the flipping of the pulley body 3. During this process, the second electric push rod 204 is activated. When the second electric push rod 204 is activated, the transmission plate 206 is driven to rise vertically by retracting the movable rod. Then, the second guide rod 205 drives the second frame 201, the first frame 2, and the leading components installed on the first frame 2 and the second frame 201 to rise. This process on one side provides enough space for the pulley body 3 to flip. Its specific function and cooperation relationship are explained in the flipping mechanism section.

[0071] Example 2 differs from Example 1 in that the detection mechanism includes a support plate 5 rotatably mounted on the second frame 201, with an out-of-roundness detection component installed at one end of the support plate 5 and a reinforcing rib detection component installed at the other end.

[0072] The second frame 201 is also rotatably mounted with a driven disk 402 and a driving disk 401 that cooperate with each other. A driving gear is coaxially fixed on the rotating shaft of the driven disk 402. The driving gear meshes with a driven gear 403 that is coaxially fixed on the rotating shaft of the bearing plate 5.

[0073] The second frame 201 is fixed with a protective cover 404 for protecting the driving disk 401, the driven disk 402, the driven gear 403, and the driving gear. A motor 4 is fixed on the protective cover 404, and the output shaft of the motor 4 is coaxially fixed with the driving disk 401.

[0074] In this embodiment of the invention, when the motor 4 is working, it drives the active disk 401 to rotate through its output shaft. When the active disk 401 rotates one revolution, it drives the driven disk 402 to rotate at a certain angle. When the driven disk 402 rotates, it drives the bearing plate 5 to rotate through the meshing of the active gear and the driven gear 403.

[0075] Among them, the active disc 401 and the driven disc 402 are the Maltese cross movement used in the prior art. Their main function is to transmit the gear at equal angles and have a self-locking effect. The active gear is a small gear and the driven gear 403 is a large gear to achieve the effect of speed reduction and torque increase. Ultimately, when the active disc 401 rotates one revolution, the bearing plate 5 rotates 3°, and it has a self-locking function when it is not rotating, so as to avoid angle changes when the out-of-round detection component and the reinforcing rib detection component are working.

[0076] It should also be noted that the motor 4 in this invention is a high-precision servo motor. Of course, a stepper motor or DC motor can also be used. This invention does not impose specific limitations, as long as the driving requirements are met.

[0077] The reinforcing rib detection assembly includes two movable slots 507 opened at one end of the bearing plate 5. A detection head 508 is slidably installed in each of the two movable slots 507. The two detection heads 508 are also slidably connected by a synchronous transmission rod 509. The distance between the two movable slots 507 gradually increases.

[0078] A third gear 5014 is rotatably mounted between the two No. 1 detection heads 508 on the synchronous transmission rod 509;

[0079] A motor bracket 5011 is slidably mounted on the support plate 5. A second motor 5012 is fixed on 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 through a transmission chain. The second gear 5013 meshes with the third gear 5014. The motor bracket 5011 is rotatably connected to the third gear 5014 or the synchronous transmission rod 509 through a connecting plate 5010 fixed thereto.

[0080] A rack 5015 is fixed on the bearing plate 5, and the rack 5015 meshes with the third gear 5014;

[0081] The motor bracket 5011 has a through groove at its bottom;

[0082] The support plate 5 is also equipped with a feedback component that cooperates with the first detection head 508.

[0083] In this embodiment of the invention, when the No. 2 motor 5012 is working, its output shaft drives the No. 2 gear 5013 to rotate through the transmission chain, so that the No. 2 gear 5013 drives the No. 3 gear 5014 to rotate through the meshing of the No. 2 gear 5013 and the No. 3 gear 5014. When the No. 3 gear 5014 rotates, it moves horizontally through the meshing of the rack 5015. When the No. 3 gear 5014 moves horizontally, it drives the two No. 1 detection heads 508 to move synchronously through the synchronous transmission rod 509. At the same time, the motor bracket 5011 moves in the same direction through the connecting plate 5010.

[0084] The two No. 1 detection heads 508 will gradually move in opposite directions as the distance between the two movable grooves 507 increases. Please refer to the pulley body 3 in this invention. The distance between its two reinforcing ribs is smaller as it gets closer to the center of the pulley body 3. The movement trajectory of the No. 1 detection head 508 in this invention is the same as the characteristics of the reinforcing ribs of the pulley body 3, so it can detect whether the distance between the two reinforcing ribs of the pulley body 3 is abnormal.

[0085] In this invention, the two No. 1 detection heads 508 move from the beginning of the stroke to the end of the stroke to complete one detection operation, and move from the end of the stroke to the beginning of the stroke to complete another detection operation. Thus, the No. 2 motor 5012 in this invention can output in both directions, and the detection efficiency is improved by performing detection in both reciprocating motions.

[0086] The feedback component includes a mounting groove 5026 opened on the side of the support plate 5 away from the out-of-roundness detection component. Two guide rods 5021 are fixed in the mounting groove 5026. A slide plate is slidably mounted on the guide rods 5021. A spring 5022 is sleeved on each of the two motors 5012. One end of the spring 5022 is fixed to the slide plate, and the other end is fixed to the inner wall of the mounting groove 5026. A marker pen 5020 is slidably mounted on the slide plate. A spring 5023 is also sleeved on the slide plate. One end of the spring 5023 is fixed to the marker pen 5020, and the other end is fixed to the slide plate.

[0087] The marking pen 5020 is connected to a drive unit mounted on the support plate 5, and the drive unit communicates with the movable slot 507.

[0088] In this embodiment of the invention, the marker pen 5020 is driven by a driving component to move vertically downward or horizontally. When the marker pen 5020 moves vertically downward, it leaves a mark at the corresponding position of the pulley body 3, while when it moves horizontally, it leaves a line at the corresponding position.

[0089] Here, a point corresponds to the current position where the test is completed and the result is satisfactory, while a line corresponds to the current position where the test is completed and the result is unsatisfactory.

[0090] It should also be noted that the force required to compress the second spring 5023 is greater than that required to compress the first spring 5022, and the tip of the marker pen 5020 can elastically extend and retract. Elastic extension and retraction means that when the tip is subjected to force, it retracts and compresses the internal elastic component, and when it is not subjected to force, it releases the elastic potential energy of the elastic component to drive the tip to return to its original position.

[0091] The driving component includes a force-receiving block 5024 fixed to one side of the marker pen 5020, and the force-receiving block 5024 is provided with an inclined portion 5025;

[0092] A push plate 5017 is slidably installed on the side of the force-bearing block 5024 away from the marker pen 5020. A roller 5019 that cooperates with the force-bearing block 5024 and the inclined part 5025 is rotatably installed on the side of the push plate 5017 facing the marker pen 5020.

[0093] The support plate 5 is also fixed with a fourth electric push rod 5016, the movable rod of the fourth electric push rod 5016 is slidably connected to the push plate 5017, and the support plate 5 is also fixed with an electromagnet 5018, the movable rod of the electromagnet 5018 is slidably connected to the push plate 5017.

[0094] In this embodiment of the invention, when the active groove 507 completes the detection, it drives the fourth electric push rod 5016 to work. When the fourth electric push rod 5016 works, it pushes the push plate 5017 toward the marker 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.

[0095] When the test result is unqualified, the push plate 5017 is driven to descend by the electromagnet 5018. When the push plate 5017 and the roller 5019 move, they cooperate with the inclined part 5025 to drive the marker pen 5020 to descend. The stroke of the push plate 5017 will increase. It will also move horizontally when the tip of the marker pen 5020 contacts the pulley body 3 to leave a dot mark, so as to leave a line mark on the pulley body 3.

[0096] The functions of spring 5023 (number two) and spring 5022 (number one) are both to provide the power required for the marker pen 5020 to reset after it moves.

[0097] The out-of-roundness detection component includes a mounting plate 501 that is slidably installed on the bearing plate 5 at the end away from the reinforcing rib detection component. Multiple second detection heads 5027 are fixed on the mounting plate 501 facing the reinforcing rib detection component.

[0098] A slider 505 is slidably mounted on the support plate 5. A second guide wheel 503 is also fixed on the support plate 5. The movable rod of the second guide wheel 503 is fixed to the slider 505. The slider 505 is connected to the mounting plate 501 through a traction rope 504. A second guide wheel 503 and a first guide wheel 502 for limiting the second guide wheel 503 are rotatably mounted on the support plate 5.

[0099] In this embodiment of the invention, the roundness of the pulley body 3 is detected by the second detection head 5027. Since the bearing plate 5 rotates at equal intervals, the mounting plate 501 is driven to rotate around the center of the bearing plate 5, thereby realizing the detection work.

[0100] During the detection process, since the pulley body 3 involves flipping, in order to avoid interference between the flipping of the pulley body 3 and the mounting plate 501, the third electric push rod 506 is driven to work. When the third electric push rod 506 works, it pushes the slider 505 to move, so that the slider 505 pulls the traction rope 504, and then the mounting plate 501 is raised vertically under the pull of the traction rope 504.

[0101] Example 3 differs from Example 1 and / or Example 2 in that: the flipping mechanism includes rectangular slots formed on two secondary frames 201, with limiting members 602 slidably installed in the rectangular slots, and transmission rods 6 fixed on opposite sides of the two limiting members 602. A transmission cylinder 601 is sleeved on the transmission rod 6 and slidably engaged with it. The transmission rod 6 is connected to a relatively moving member installed on the secondary frame 201, and the transmission rod 6 is connected to a rotating member installed on the secondary frame 201.

[0102] In this embodiment of the invention, when the relative moving parts are working, they will drive the two transmission rods 6 and the limiting part 602 to move relative to each other in order to clamp the pulley body 3.

[0103] When the rotating component is working, it drives the transmission rod 6 and the transmission cylinder 601 to rotate, so that the rotation of the transmission rod 6 drives the limiting component 602 and the pulley body 3 to rotate.

[0104] The transmission rod 6 has multiple transmission bars fixed at equal intervals around its circumference. The transmission bars slide in conjunction with the transmission grooves opened 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.

[0105] The relative moving parts include L-shaped rack plates 603 slidably mounted on two second frames 201, the L-shaped rack plates 603 being rotatably connected to the transmission rod 6, and a fourth gear 609 that meshes with the L-shaped rack plates 603 is also rotatably mounted on the second frame 201.

[0106] The L-shaped rack plate 603 has a through groove 604, and an active rack plate that meshes with the fourth gear 609 is installed in the through groove 604. The active rack plate is fixed to the first frame 2.

[0107] An electric push rod 202 is fixed on the side of the second frame 201 away from the fourth gear 609, and the movable rod of the first electric push rod 202 is fixed to the first frame 2.

[0108] In this embodiment of the invention, when the first electric push rod 202 is working, it drives the first frame 2 to rise vertically. The vertical rise of the first frame 2 is to prevent the pulley body 3 from interfering with the bearing plate 5 and the first frame 2 when it is flipped.

[0109] When frame 2 rises, it drives the active rack plate to rise as well. The rise of the active rack plate drives gear 609 to rotate. When the two synchronous transmission rods 509 rotate, they mesh with the two L-shaped rack plates 603 to drive the two L-shaped rack plates 603 to move relative to each other, thereby driving the two transmission rods 6 to move relative to each other.

[0110] Among them, the above-mentioned second electric push rod 204 drives the second frame 201 to rise after clamping the pulley body 3, so that the pulley body 3 does not interfere with the partition 102 when it is flipped. This process drives the rotating parts to work.

[0111] The rotating component includes a worm gear 608 coaxially fixed on the transmission cylinder 601, a worm 607 rotatably mounted on one side of the worm gear 608, and a ratchet 606 coaxially fixed at one end of the worm 607. The ratchet 606 engages unidirectionally with a pawl plate 605 fixed on the partition plate 102.

[0112] In this embodiment of the invention, when the second frame 201 is erected and raised, the ratchet 606 and the worm gear 607 are driven to rotate by the cooperation of the ratchet 606 and the pawl plate 605, so that when the worm gear 607 rotates, it drives the worm wheel 608 and the transmission cylinder 601 to rotate, thereby driving the pulley body 3 to rotate.

[0113] After the pulley body 3 rotates 180°, it descends. During the descent, the ratchet 606 does not have a transmission relationship with the pawl plate 605, so the pulley body 3 will not rotate.

[0114] This invention also provides a detection method for automotive transmission pulley processing, employing the aforementioned detection device for automotive transmission pulley processing, characterized by comprising the following steps:

[0115] Step 1: Open the box door 101 and place the pulley body 3 in the designated position, then close the box door 101;

[0116] Step 2: The reinforcing ribs and roundness of the pulley body 3 are inspected by the testing agency;

[0117] Step 3: The pulley body 3 is flipped using a flipping mechanism, and the other side of the pulley body 3 is inspected.

[0118] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
