Description

Technical Field

[0001] The utility model relates to the technical field of roller chain processing, in particular to a roller chain flexibility detection device. Background Art

[0002] Roller chain is a type of chain drive used to transmit mechanical power. It is widely used in household, industrial and agricultural machinery, including conveyors, plotters, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers linked together and driven by a gear called a sprocket. It is a simple, reliable and efficient power transmission device.

[0003] Roller chains are usually composed of inner link plates, outer link plates, pins, sleeves and rollers. The inner link plates and sleeves, the outer link plates and pins are interference fits; the rollers and sleeves, the sleeves and pins are clearance fits. During operation, the inner and outer chain links can bend relative to each other, the sleeves can rotate freely around the pins, and the rollers are sleeved on the sleeves to reduce the wear between the chain and the sprocket.

[0004] The flexibility test of the chain should be carried out after assembly and before lubrication, and the pitch number of the tested chain segment is specified. When the running wheels and guide wheels are turned by hand, the chain links should be able to rotate flexibly and freely at a certain angle. When the tested chain segment is lifted to the other end off the ground, observe whether it can droop straightly without any obstruction. At present, the above two methods are used to manually test the flexibility of the roller chain. On the one hand, it is time-consuming, labor-intensive and inefficient. At the same time, during the test process, when the flexibility between the chain links is low or even stuck, it is easy to cause a certain degree of damage to the detection device. On the other hand, the accuracy of the test results is also low, and the detection of the flexibility between the links on the roller chain is not comprehensive enough. Based on this, it is necessary to design a new type of roller chain flexibility detection device. Utility Model Content

The plurality of groups of brush drums are arranged on both sides of the link track at one end of the second roller, and the brushes rotatably arranged thereon are in contact with the chain roller. The scanning component includes a scanner. The scanner is arranged in two groups and is respectively fixed on both sides of the link track at the other end of the second roller.

[0011] Furthermore, guiding frames for guiding the chain are arranged before and after the position of the painting component on the link track. The guiding frames include guiding rods rotatably arranged at both ends on the link track and connecting seats located above the chain and connected to the upper ends of the guiding rods.

[0012] Furthermore, the bottoms of the plurality of groups of brush drums are respectively installed on both sides of the link track through adjusting seats arranged at the adapted positions of the link track.

[0013] Furthermore, the second roller is adapted to slide on the frame body through an adapted sliding seat arranged at the bottom of the frame body. The sliding seat includes a sliding rod. An adapted seat body arranged at the bottom of the second roller is slidably arranged on the sliding rod, and both sides of the seat body are connected to compression springs sleeved on the sliding rod.

[0017] Compared with the prior art, the utility model has the following advantages and effects:

[0018] The utility model is a roller chain flexibility detection device. The roller groups distributed in a staggered manner on the frame can increase the running path of the tested chain segment during the movement, and on the other hand, further increase the frequency of different angle changes on its running path, thereby further improving the flexibility between the roller chain links during the detection process, and further improving the accuracy and precision of the measurement data of this measuring device.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0026] See also Figure 1-2 The present embodiment relates to a roller chain flexibility detection device, including a frame 100, on which roller groups 1 distributed in an alternating manner are rotatably arranged, and the rollers at corresponding positions are driven to rotate by corresponding driving components arranged on the frame 100, and a link track 2 adapted to the link track formed on the roller group 1 is arranged below the link track, and a roller table composed of a plurality of roller shafts 21 is rotatably arranged on the link track 2.

[0027] Specifically, in this embodiment, when the segment 110 to be detected is being detected, it is wound around the link track formed by the roller sets 1 that are staggeredly distributed on the frame 100. The roller sets 1 can drive the segment 110 to be measured to perform a reciprocating winding movement along the link track 2 below the link track under the corresponding drive of the corresponding drive components, so as to detect the flexibility between the links 111 of the segment 110 to be measured. On the one hand, the roller sets 1 that are staggeredly distributed on the frame 100 can increase the running path of the segment 110 to be measured during the movement process. On the other hand, it also further increases the frequency of different angle changes on its running path, thereby further improving the flexibility between the roller chain links 111 during the detection process, and further improving the accuracy and precision of the measurement data of this measurement device. In addition, the adaptive setting of the link track can play a certain guiding role for the segment 110 to be measured during the test process. And a roller path composed of a plurality of roller shafts 21 is rotatably arranged on the link track 2, which can play a certain auxiliary rotation role for the segment 110 to be measured during the rotation process and further reduce the wear degree on the link track 2. In addition, the link track 2 can also ensure that the segment 110 to be measured maintains a certain angle when rotating on the link track formed by the roller sets 1, thereby ensuring that the segment 110 to be measured has a certain smoothness and flexibility during the rotation process, and further improving the detection accuracy of this detection device. At the same time, in view of the problems such as jamming or even dead joints of the link 111 of the segment 110 to be measured during the detection process, resulting in a certain degree of deformation of the segment 110 along its link track, the setting of the roller sets 1 cooperating with the link track 2 can clamp the segment 110 to be measured in the first time, and make its drive component stop running immediately, and the roller sets 1 then stop rotating, thereby reducing the damage degree to the roller sets 1, the drive component and the link track 2, avoiding further damage to the segment 110 to be measured, ensuring the stable operation and service life of this detection device, and further improving the detection efficiency.

[0028] The roller sets 1 rotatably arranged on the frame 100 include a first roller 11, a second roller 12 and a third roller 13. The first roller 11, the second roller 12 and the third roller 13 are arranged in a "Ji" shape. The first roller 11 and the third roller 13 are respectively driven to rotate by a first drive component 101 and a second drive component 102 arranged on the frame 100. Specifically, the arrangement in the "Ji" shape can be referred to Figure 1As shown in , the roller group 1 can drive the roller group 1 and the measured segment 110 to rotate back and forth in a single direction or in different directions in the corresponding link track 2 on the frame 100 by controlling the first driving component 101 and the second driving component 102 connected to the first roller 11 and the third roller 13 respectively according to specific usage requirements. The roller group 1 arranged in this way cooperates with the link track formed to further improve the angle change of the measured segment 110 during the rotation process, so that the rotation process of the measured segment 110 is more intuitive and comprehensive when the flexibility detection is performed on the measured segment 110, and the relative rotation range between the links 111 is large, which further improves the detection effect and detection flexibility of this detection device.

[0029] The side of the link track 2 at the corner is provided with an arc-shaped second roller 22 composed of a plurality of rollers 21. Figure 1 or Figure 5 As shown in the figure, the arc-shaped second roller 22 at the corner position on the link track 2 can further improve the stability of the measured segment 110 in rotating along the link track of the roller group 1 and the link track 2 below it during the detection process and play a certain guiding role, avoiding the phenomenon that the measured segment 110 derails and affects the normal detection process or even causes equipment damage. At the same time, the arc-shaped second roller 22 composed of a plurality of rollers 112 can play a certain protective role, and reduce the further damage to the measured segment 110 itself and the link track 2 caused by the jamming of the chain links 111 of the measured segment 110, thereby improving the overall structural strength of the link track 2.

[0030] The link track 2 is provided with a brushing assembly 3 for brushing the chain roller 112 and a scanning assembly 4 for scanning the roller 112. The brushing assembly 3 and the scanning assembly 4 are placed on the link track formed by the roller groups 1 on both sides of the second roller 12. The brushing assembly 3 includes multiple groups of roller brush cylinders 31 and roller brushes 311 rotatably arranged thereon. The multiple groups of roller brush cylinders 31 are placed on both sides of the link track 2 at one end of the second roller 12, and the roller brushes 311 rotatably arranged thereon are in contact with the chain roller 112. The scanning assembly 4 includes a scanner 41. The scanner 41 is arranged into two groups and is respectively placed on both sides of the link track 2 at the other end of the second roller 12 to be fixed. The specific structures of the brushing assembly 3 and the scanning assembly 4 can be respectively referred to. Figure 3 and Figure 4As shown in , different colors of paint can be added to the roller brush barrel 31 according to the use requirements without affecting the normal use of the roller chain. When the tested segment 110 rotates to the position of the paint brush component 3 during the detection process, the roller brush 311 placed on both sides of the link track 2 and in contact with the chain roller 112 can rotate accordingly. At the same time, the roller brush 311 can apply the paint filled in the roller brush barrel 31 to the chain roller 112 during the rotation process, and with the rotation of the tested segment 110 and its roller 112, a paint mark within a certain range can be formed on the roller 112 under the action of the paint brush component 3. Then, as the roller group 1 drives the tested segment 110 to rotate continuously and the roller 112 is continuously painted, when the roller 112 with the painted mark moves along the link track 2 to the other end of the second gear, the surface of the roller 112 on the tested segment 110 can be scanned and detected by the scanner 41 of the scanning component 4 provided at the matching positions on both sides of the link track 2. Specifically, the scanner 41 of the scanning component 4 is tested in advance with the painting component 3 before use, so that a threshold value within a certain range is set according to the size of the paint mark area on the surface of the roller 112 tested when the roller 112 rotates normally, so that the scanner 41 can judge the flexibility of the rotation of the roller 112 according to the specific paint mark area on the surface of the roller 112. This detection device can not only detect the flexibility between the links 111 of the roller chain through the setting of the painting component 3 and the scanning component 4, but also can further detect the roller 112 on the roller chain, so as to realize a comprehensive detection of the roller chain, further improve the comprehensiveness of the flexibility detection of this roller chain and the accuracy and precision of the detection data. In addition, the paint selection in the roller brush barrel 31 can also be added with lubricant according to the use requirements. The adaptable shape and size of the roller brush barrel 31 can lubricate the links 111 and the roller 112 on the tested chain segment 110 to meet different use requirements and increase applicability and practicality.

[0031] A guide frame 5 for chain guiding is arranged before and after the painting assembly 3 on the link track 2. The guide frame 5 includes a guide rod 51 rotatably arranged on the link track 2 at both ends and a connecting seat 52 located above the chain and connected to the upper end of the guide rod 51. Figure 2 or Figure 5As shown in the figure, the position setting of the guide frame 5 on the link track 2 enables the guide rods 51 rotatably arranged at both ends to properly rotate and guide the chain links 111 during the rotation of the measured chain segment 110, thereby ensuring that the chain links 111 can pass through the painting component 3 more smoothly, thereby improving the stability of the painting component 3 during the painting process. At the same time, the guide rod 51, under the action of the connecting seat 52 at its upper end, makes the guide frame 5 structure more stable and can further avoid the shaking or even deviation of the measured chain segment 110 during the rotation, thereby ensuring the stability of the detection process.

[0032] The bottoms of the plurality of roller brush cylinders 31 are all mounted on both sides of the link track 2 through the adjustment seats 32 provided at the matching positions of the link track 2. Figure 5 As shown, the adjustment seat 32 structure at the bottom of the roller brush cylinder 31 can adopt a common adjustment bolt 321 structure, and the relative position of the roller brush cylinder 31 on both sides of the link track 2 can be adjusted by rotating the adjustment bolt 321, so that the roller brush cylinders 31 on both sides are adjusted to the optimal brushing position according to the specific rotation trajectory of the measured segment 110 on the link track 2, so that the roller brush 311 is in contact with the roller 112 and the stability of the brushing is guaranteed, and at the same time, unnecessary damage to the brush cylinder caused by the measured segment 110 during the rotation process can be avoided as much as possible.

[0033] The second roller 12 is adapted to slide on the frame 100 through an adapting slide seat 6 provided at the bottom of the frame 100. The slide seat 6 includes a slide bar 61. The adapting seat body 121 provided at the bottom of the second roller 12 is slidably provided on the slide bar 61, and the two sides of the seat body 121 are connected to the compression springs 611 provided on the slide bar 61. The specific structure of the slide seat 6 can be seen in Figure 6As shown, during the rotation of the second roller 12, the seat body 121 structure adapted at the bottom thereof can also slide within a certain range in the slide groove provided at the corresponding position of the frame 100. During the rotation of the measured chain segment 110, the adapted seat body 121 of the second roller 12 can drive the slide bar 61 of the slide seat 6 provided at the bottom of the frame 100, and slide slightly under the action of the compression springs 611 sleeved on the slide bars 61 on both sides of the seat body 121, and the sliding amplitude is not enough to affect the normal operation of the second roller 12 and the measured chain segment 110. This design method can avoid the situation where there is a jam or even a dead joint between the chain links 111 on the measured chain segment 110, and the measured chain segment 110 is driven by the driving component to generate a certain degree of tensile stress on the measured chain segment 110. When this situation occurs, the second roller 12 slidingly provided on the slide seat 6 of the frame 100 The roller 12 can play a certain buffering role, thereby further reducing the degree of damage to the measured segment 110 and the driving components, ensuring stability during the detection process and appropriately extending the service life. In addition, the compression springs 611 placed on the slide bars 61 on both sides of the second roller 12 adapter seat 121 can be set with different elastic stress sizes. Specifically, the elastic stress of the compression spring 611 on one side of the seat 121 that extends and retracts the second roller 12 in a direction relatively away from the first roller 11 and the third roller 13 is greater than the elastic stress of the compression spring 611 on the other side of the seat 121. This setting can further improve the stability of the measured segment 110 during rotation, ensure that the measured segment 110 between the roller group 1 has a certain tension, and can further reduce the sliding amplitude of the second roller 12 during rotation and the vibration amplitude of the measured segment 110, further avoiding unnecessary influence on the detection process.

[0034] The link track 2 is arranged in a segmented structure and is placed under the link track formed by the first roller 11 and the third roller 13 of the roller group 1. The link track 2 is arranged in a segmented structure and in a corresponding position of the frame 100. While ensuring the normal rotation of the measured segment 110, on the one hand, it can avoid the phenomenon that a certain angle change occurs between the chain links 111 of the measured segment 110 during the sliding process of the second roller 12, which causes the measured segment 110 to have a position deviation relative to the link track 2 and affects the normal rotation process; on the other hand, it is also convenient for installing, disassembling and replacing the link track 2 at the corresponding position according to the different position settings of the roller group 1 to meet different usage conditions and usage requirements.

[0035] See also Figure 6Contact sensors 7 are provided at corresponding positions on both sides of the slide 6 and on both sides of the adapter seat 121 provided at the bottom of the second roller 12. To ensure normal use and placement of the adapter seat 121 of the second roller 12 in a stationary state, the position setting does not contact the contact sensors 7 on the seat bodies 121 on both sides. Specifically, when there is a jam or even a dead joint between the chain links 111 on the measured segment 110, causing the driving component to stop running and unable to rotate, the measured segment 110 is subjected to a certain tensile stress generated when the driving component stops rotating and drives the adapter seat 121 of the second roller 12 to slide to a certain distance along the slide rod 61 on the slide 6 to one side of the slide 6, the contact sensor 7 on the seat body 121 contacts the contact sensor 7 provided at the corresponding position on one side of the slide 6 and issues an alarm to prompt The operator makes timely adjustments and processing to reduce damage to the equipment and improve the safety of the detection device during operation. At the same time, the signal line of the contact sensor 7 can be connected to the signal line of the driving component through the controller. If the driving motor cannot stop rotating in the first time when the above situation occurs and continues to generate tensile stress on the measured chain segment 110, and the adapter seat 121 of the second roller 12 slides on the slide 6 and triggers the contact sensor 7, the contact sensor 7 sends a signal through the signal line and under the action of the controller, sends the processed signal to the driving component and cuts off the power supply of the driving component to stop the driving component from working, thereby avoiding the phenomenon that the driving component continues to operate and is easily damaged when such a situation occurs, and plays a certain protective role for the driving component.

[0036] The frame 100 is also provided with a human-machine interactive display screen 8. The roller chain flexibility detection device can control and adjust the roller group 1 and its driving components, the brush component 3, the scanning component 4 and the contact sensor 7 arranged thereon through the human-machine interactive display screen 8, thereby improving the convenience and flexibility of operation, and can monitor and observe the real-time status and detection data of the detection device, thereby improving the stability of equipment operation and the accuracy of measurement data during the measurement process.
