Description

Technical Field

[0001] The present invention relates to the technical field of factory inspection devices, and particularly relates to a sprocket factory inspection device and an inspection method. Background Technique

[0002] As is well known, a sprocket is a common mechanical transmission component, and its main function is to transfer power from one shaft to another through a chain. A sprocket generally has a specific tooth profile to precisely mesh with the chain and ensure a smooth power transmission process. To ensure the meshing accuracy of the sprocket, we propose a sprocket factory inspection device and an inspection method to facilitate the inspection of sprockets after production.

[0003] After retrieval, the patent with the Chinese patent application number CN202021206217.5 discloses an automated inspection device applicable to sprockets, which generally includes a workbench and a four-axis robot. The four-axis robot is arranged on the workbench and is used to carry parts. The automated inspection device applicable to sprockets also includes a keyway inspection module, an inner diameter inspection and engraving module, and a loading module. The keyway inspection module, the inner diameter inspection and engraving module, and the loading module are all arranged on the workbench on one side of the four-axis robot. During operation, the four-axis robot transports the parts to the first part fixing block in the keyway inspection module, the first cylinder starts to drive the parts to move, and when it moves to the position of the movable plate, the first motor starts to drive the parts to rotate. When the inner keyway of the parts rotates to the position of the movable key, the movable key pops out, and the second cylinder drives the movable key to move in the keyway of the parts to complete the inspection of the keyway. At the same time, we also retrieved that the invention patent with the Chinese patent application number CN202410563022.2 discloses a portable chain link number detection device and its usage method, which is generally described as including a bottom plate. A chain guiding mechanism is arranged on the bottom plate, and a sprocket counting and detecting mechanism is arranged on the chain guiding mechanism. An intelligent counter connected to the sprocket counting and detecting mechanism is arranged on the bottom plate. The chain guiding mechanism is used to guide the movement of the chain on the bottom plate, and the sprocket counting and detecting mechanism is used to count and detect the guided moving chain and transmit the detection result signal to the intelligent counter. The intelligent counter is used to process the detection result signal and display the detection result. When in use, it can accurately detect the number of links of a long chain by counting and detecting the guided moving chain by the sprocket counting and detecting mechanism and converting the number of rotations of the sprocket into the number of links of the chain.

[0004] In the above two prior art solutions, in the solution with the application number CN202021206217.5, only the keyway was detected correspondingly during the detection process, and the detection content needs to be further enriched. In the solution with the application number CN202410563022.2, corresponding detection is formed through the interaction between the chain and the sprocket. Although the detection of the sprocket can also be achieved by switching the detection objects between the chain and the sprocket, the detected items are also limited to the transmission effect between the chain and the sprocket, and the detection content of the sprocket's own quality also needs to be further enriched. Summary of the Invention

[0015] Preferably, a synchronous plate is installed on the telescopic rod of the electric telescopic rod, and the synchronous plate is fixedly connected to the lifting frame.

[0016] Preferably, installation grooves are formed in both of the pushing heads, straight springs are fixedly connected in both of the installation grooves, and alignment cone blocks are fixedly connected to both of the straight springs.

[0017] A detection method for a sprocket factory inspection device includes the following steps:

[0018] S1. When in use, first install the overall spatial structure of the sprocket factory inspection device. The installation position is set according to the production environment of the sprocket. It is best to facilitate the direct placement of the sprocket relative to the stepping conveyor belt after the sprocket production is completed. Then, complete the electrical installation of the intelligent digital display screen, laser scanner, adjustment structure, electromagnet, and stepping conveyor belt, and complete the data connection between the pressure sensor and the central controller;

[0019] S2. The stepping conveyor belt is powered on and runs to convey the sprockets placed on it. Along with the conveyance of the sprockets and the production sequence of the sprockets, the produced sprockets are placed on the moving stepping conveyor belt. When the stepping conveyor belt transports the sprockets to the area corresponding to the clamping end for operation, the adjustment structure runs to realize the rotational adjustment of the three-way pipe, and the two tightening members are adjusted to a state of one above the other. During the rotational adjustment of the three-way pipe, both of the electromagnets are energized to generate electromagnetic fields. Under the relative magnetic action of the electromagnetic fields and the first permanent magnet and the second permanent magnet, both of the pushing springs are compressed, and both of the tightening members are in a state of approaching the middle partition frame. The two traction rods respectively form a relatively approaching state relative to the two connecting rods, that is, the overall length between the connecting rod and the traction rod that are connected in a matching manner through the connecting cylinder is the shortest. Therefore, in this state, the pushing head will form a widening effect at the tail end relative to the tightening member;

[0020] S3. Then, by cutting off the circuit of one of the electromagnets close to the lower side among the two electromagnets, the pushing head located on the lower side will form a relative downward movement and separation relative to the tightening member under the action of its own gravity, and the tightening member will also form a downward movement relative to the three-way pipe under the pushing action of the corresponding pushing spring, so that the pushing head and the tightening member will be inserted into the shaft hole of the sprocket to be clamped in sequence. After the tightening member is inserted into the sprocket to the limit depth, the electromagnet with the cut-off circuit will be reconnected to form a circuit. Thereafter, the pushing head will form a widening again at the tail end relative to the tightening member. And during this process, the adjustment structure will control the limit depth insertion state of the tightening member relative to the shaft hole of the sprocket. When the central controller receives the detection value of the pressure sensor, and when the friction force formed by the pressure detection value with the sprocket increases to be able to overcome the self-gravity of the sprocket, the adjustment structure runs to realize the elevation of the three-way pipe, that is, the lifting of the sprocket relative to the stepping conveyor belt is completed;

[0021] S4. When the lifting height of the sprocket allows the entire clamping end and the sprocket carried by it to form a flip without causing rotational interference to the step conveyor belt, the adjustment structure moves to achieve the overall flip of the clamping end and the sprocket carried by it, thereby realizing the alternating conversion of the up-and-down states of the two tightening members. Therefore, the sprocket clamped in the previous step flips into the upper side. The adjustment structure operates to reduce the overall height of the clamping end, and repeats the method of accurately clamping relative to the sprocket in the previous step to achieve the clamping of another sprocket. During the sprocket clamping process, due to the failure of the electromagnetic field generated by the electromagnet, and the corresponding tightening member will be pushed away relative to the middle partition under the pushing action of the pushing spring, so the rotational driving effect of the adjustment structure on this tightening member fails. After the electromagnet is energized, it will cause the pushing spring to be compressed, and the tightening frame moves closer to the middle partition, so the rotational driving effect of the adjustment structure on this tightening member is effective. By operating the adjustment structure to drive the corresponding detected sprocket to rotate, and matching the laser scanner to perform corresponding scanning on the tooth profile of the sprocket, the corresponding detection of the sprocket is realized.

[0022] Advantages

[0023] Compared with the prior art, the present invention provides a sprocket factory inspection device and inspection method, which have the following advantages:

[0024] 1. In the present invention, through the design of the detection end, a corresponding detection functional component is formed with the supporting sprocket to perform corresponding detection on the sprocket, and the detection steps are relatively simple.

[0043] It should be further explained that a stepping conveyor belt is installed on the workbench 1, and the stepping conveyor belt is used for conveying loading and unloading during the sprocket detection process. The stepping conveyor belt includes a cloth hanging frame 33, which is fixedly connected to the workbench 1, and an active roller 34 and a driven roller 35 are installed on the cloth hanging frame 33. A conveyor belt body 36 is transmission-connected between the driving roller and the driven roller 35, and a plurality of circular holes 37 are provided on the conveyor belt body 36. A stepping motor for rotating and driving the active roller 34 is installed on the cloth hanging frame 33.

[0044] The central controller, intelligent digital display screen, laser scanner, pressure sensor 8, electromagnet 13, first servo motor 20, second servo motor 23, third servo motor 24, stepper motor and electric telescopic rod 22 in this embodiment are all conventional equipment purchased on the market and known to those skilled in the art. In the present invention, we only use them without improving their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual, and will not be described in detail here.

[0045] In summary, the working process of the sprocket factory inspection device and the inspection method is as follows. When in use, first install the overall spatial structure of the sprocket factory inspection device. The installation position is set according to the production environment of the sprocket. It is best to facilitate the direct placement of the sprocket relative to the stepping conveyor after production. Then, complete the electrical installation of the intelligent digital display screen, laser scanner, adjustment structure, electromagnet 13, and stepping conveyor. The electrical installation of the adjustment structure is the electrical installation of the first servo motor 20, the second servo motor 23, the third servo motor 24, and the electric telescopic rod 22. Among them, when the first servo motor 20 is powered on and operates, it realizes the left-right position movement of the moving frame 19 relative to the workbench 1, that is, realizes the left-right position movement of the three-way pipe 4. When the second servo motor 23 is powered on and operates, it realizes the rotation drive and control of the three-way pipe 4. When the third servo motor 24 is powered on and operates, it realizes the drive of the transmission shaft 26, and then realizes the rotation drive of the outer cylinder 16 that can be driven by transmission, and completes the data connection between the pressure sensor 8 and the central controller. The stepping conveyor is powered on and operates to realize the transportation of the sprockets placed on it. Along with the transportation of the sprockets and the production sequence of the sprockets, the produced sprockets are placed on the moving stepping conveyor. During the placement process, it is appropriate that the shaft hole on the sprocket is concentric with the circular hole 37 on the conveyor belt body 36 to ensure the positioning of the sprocket on the conveyor belt body 36 and also facilitate the clamping operation of the subsequent clamping end. When the stepping conveyor transports the sprocket to the area corresponding to the operation of the clamping end, the adjustment structure operates to realize the rotation adjustment of the three-way pipe 4, and adjusts the two tightening members to a one-up-one-down state. During the rotation adjustment of the three-way pipe 4, both electromagnets 13 are energized to generate electromagnetic fields. Under the relative magnetic action of the electromagnetic fields and the first permanent magnet 14 and the second permanent magnet 15, both pushing springs 7 are compressed, and both tightening members are in a state close to the middle partition 5. The two traction rods 10 respectively form a relatively close state relative to the two connecting rods 12, that is, the overall length between the connecting rod 12 and the traction rod 10 that are connected in a matching manner through the connecting cylinder 11 is the shortest. Therefore, in this state, the pushing head 9 will form a widening effect at the tail end relative to the tightening member. Then, by controlling the circuit of one of the electromagnets 13 close to the lower side among the two electromagnets 13 to be cut off, the pushing head 9 located on the lower side will form a relative downward movement and separation relative to the tightening member under the action of its own gravity, and the tightening member will also form a downward movement relative to the three-way pipe 4 under the pushing action of the corresponding pushing spring 7, so that the pushing head 9 and the tightening member will be inserted into the shaft hole of the sprocket to be clamped in sequence. After the tightening member is inserted into the sprocket to the limit depth, the electromagnet 13 with the cut-off circuit will be re-connected to the circuit. Thereafter, the pushing head 9 will form a widening effect at the tail end relative to the tightening member again. And during this process, the adjustment structure will control the limit depth insertion state of the tightening member relative to the shaft hole of the sprocket. When the central controller receives the detection value of the pressure sensor 8, and when the friction force formed by the pressure detection value with the sprocket increases to be able to overcome the self-gravity of the sprocket, the adjustment structure operates to realize the elevation of the three-way pipe 4.That is, the lifting of the sprocket relative to the step conveyor is completed.,

[0046] Furthermore, when the lifting height of the sprocket allows the clamping end as a whole and the sprocket it carries to flip over without causing rotational interference to the stepping conveyor belt, the adjustment structure moves to achieve the overall flipping of the clamping end and the sprocket it carries, thereby achieving the alternating conversion of the two tensioning members into an up and down state, so that the sprocket clamped in the previous step flips into the upper side, the adjustment structure operates to achieve the overall lowering of the clamping end, and repeats the method of accurately clamping relative to the sprocket in the previous step to achieve the clamping of another sprocket. During the sprocket clamping process, the electromagnetic field generated by the electromagnet 13 fails, and the corresponding tensioning member is pushed away relative to the middle partition frame 5 under the pushing action of the pushing spring 7, so the adjustment structure has a rotational driving effect on the tensioning member. Failure, and when the electromagnet is energized, it will cause the ejection spring 7 to be compressed, and the tensioning frame will be close to the middle partition frame 5, so the adjustment structure is effective in driving the rotation of the tensioning member, and the corresponding sprocket for detection is driven to rotate through the adjustment structure, and the laser scanner is used to perform a corresponding scan on the tooth shape of the sprocket to achieve corresponding detection of the sprocket. During the sprocket detection, the laser transmitter emits a laser beam, and the photoelectric detector receives the signal of the laser beam emitted by the matching laser transmitter, and the third servo motor 24 moves to realize the rotation drive of the sprocket clamped on the tensioning member. During the rotation of the sprocket, the sprocket teeth of the sprocket will block the laser beam, so as to maintain the rotation control of the sprocket, and the photoelectric detector will detect the signal of the laser beam in stages, and record the photoelectric The light receiving time and light receiving interval time of the detector can form the tooth surface detection of the sprocket, and in the detection process, the clamping end can be equipped with a sprocket to form clamping, or the clamping end can be equipped with two sprockets to form corresponding clamping. When the two sprockets are clamped synchronously by the clamping end, the detection link should keep the sprocket near the upper side of the two clamped sprockets below the laser transmitter and above the photoelectric detector, and the sprocket near the lower side of the two clamped sprockets is below the photoelectric detector. During the detection process, the first servo motor 20 is detected to run in stages along with the rotation of the sprocket to realize the detection of different diameter positions of the sprocket to achieve the integrity detection of the gear on the sprocket, and in order to ensure the detection quality during the detection process, the second servo motor should be The two tensioning members 23 corresponding to each other keep the corresponding upper and lower positions to ensure the horizontal setting of the detected sprocket. During the sprocket detection process, the sprocket is controlled by the third servo motor 24 to rotate at different speeds in stages, and the rotation balance of the sprocket is detected in combination with the reading of the pressure sensor 8. That is, when the pressure sensor 8 does not change at a certain reading, it means that the rotation balance of the sprocket is good. If the pressure sensor 8 presents different detection parameters at different speeds, it means that the overall rotation balance of the sprocket is poor. When the two clamped sprockets are flipped with the clamping ends, the two sprockets can be controlled to enter a relative horizontal state when the relative position changes, that is, the two sprockets are at the same height.Keep the power supply of the second servo motor 23 cut off in this state. After that, if the two sprockets remain at the same height, it indicates that the masses of the two sprockets are similar. If the relative height of the two sprockets changes, it indicates that there is a difference in the masses of the two sprockets. Thus, with the sequential detection of multiple sprockets, the comparison between every two sprockets among multiple sprockets can be realized, and the deviation evaluation of the weights between multiple sprockets can be achieved.

10. A detection method for a sprocket factory detection device, characterized in that: A sprocket factory inspection device according to any one of claims 1 to 9 is used, comprising the following steps: S1. When in use, first complete the installation of the spatial structure of the sprocket factory inspection device as a whole. The installation position is set according to the production environment of the sprocket, so that the sprocket can be placed directly relative to the stepping conveyor belt after production is completed. Then complete the electrical installation of the intelligent digital display screen, laser scanner, adjustment structure, electromagnet (13) and stepping conveyor belt, and complete the data connection between the pressure sensor (8) and the central controller; S2, the stepping conveyor belt is powered on to realize the conveyance of the sprocket placed thereon, and the produced sprocket is placed on the moving stepping conveyor belt along with the conveyance of the sprocket and the production sequence of the sprocket. When the stepping conveyor belt transports the sprocket to the operation area corresponding to the clamping end, the adjustment structure is operated to realize the rotation adjustment of the three-way pipe (4), and the two tensioning members are adjusted to an up and down state. During the rotation adjustment of the three-way pipe (4), the two electromagnets (13) are energized to generate an electromagnetic field. Under the relative magnetic effect of the electromagnetic field and the first permanent magnet (14) and the second permanent magnet (15), the two ejection springs (7) are compressed, and the two tensioning members are in a state close to the middle partition frame (5). The two traction rods (10) are respectively in a relatively close state relative to the two connecting rods (12), that is, the overall length between the connecting rod (12) and the traction rod (10) that are mutually matched and connected through the connecting tube (11) is the shortest, so in this state, the pushing head (9) will form a rear end expansion effect relative to the tensioning member; S3, then, by controlling the circuit of one of the two electromagnets (13) close to the lower side to be cut off, the pushing head (9) located on the lower side will fall away relative to the tensioning member under the action of its own weight, and the tensioning member will also fall relative to the three-way pipe (4) under the pushing action of the corresponding ejection spring (7), so that the pushing head (9) and the tensioning member will be inserted into the shaft hole of the sprocket to be clamped in sequence, and after the tensioning member is inserted to the limit depth relative to the sprocket, the electromagnet (13) with the circuit cut off will be re-connected, and thereafter the pushing head (9) will be expanded again relative to the tail end of the tensioning member, and in this process, the adjustment structure will control the limit depth insertion state of the tensioning member relative to the shaft hole of the sprocket, and when the central controller receives the detection value of the pressure sensor (8), and when the friction force between the pressure detection value and the sprocket increases to the point where it can overcome the self-weight of the sprocket, the adjustment structure operates to realize the lifting of the three-way pipe (4), that is, the lifting of the sprocket relative to the stepping conveyor belt is completed; S4, when the lifting height of the sprocket allows the clamping end and the sprocket it carries to flip over without causing rotation interference to the stepping conveyor belt, the adjustment structure moves to realize the overall flipping of the clamping end and the sprocket it carries, thereby realizing the alternating conversion of the two tensioning members to the upper and lower states, so that the sprocket clamped in the previous step flips into the upper side, the adjustment structure operates, the overall height of the clamping end is lowered, and the method of accurately clamping relative to the sprocket in the previous step is repeated to realize the clamping of another sprocket. During the sprocket clamping process, due to the electromagnet (13) The electromagnetic field generated is ineffective, and the corresponding tensioning member is pushed away relative to the middle partition frame (5) under the pushing action of the pushing spring (7), so the rotational driving action of the adjustment structure on the tensioning member is ineffective. When the electromagnet is energized, the pushing spring (7) is compressed, and the tensioning frame is brought closer to the middle partition frame (5), so the rotational driving action of the adjustment structure on the tensioning member is effective. The adjustment structure drives the corresponding sprocket to be detected to rotate, and the laser scanner is used to perform a corresponding scan on the tooth shape of the sprocket to achieve corresponding detection of the sprocket.
