Description

Technical Field

[0001] The present application relates to the field of chain quality inspection devices, and in particular to an automatic chain performance detection device. Background Art

[0002] The transmission chain is a common transmission part in mechanical equipment. The transmission chain includes outer link plates, inner link plates and chain pins. The outer link plates and inner link plates are arranged alternately, and the chain pins pass through the outer link plates and the inner link plates in sequence. Multiple chain plates and chain pins are combined to form a ring structure. The user puts the chain on two sprockets, which can make the two sprockets rotate synchronously to achieve a transmission effect.

[0003] After the chain is produced, it is necessary to test the production quality. By checking the distance between each chain pin and the adjacent chain pins on the chain, it can be determined whether the production quality of the chain meets the standards and reduce the probability of the chain and sprocket failing to mesh and becoming disconnected.

[0004] The above-mentioned related technical solutions have the following defects: when there are many chain pins on the chain, it is time-consuming and laborious to use a measuring tool to measure the distance between the chain pins on the chain, resulting in low detection efficiency. Summary of the invention

[0005] In order to improve the efficiency of chain production quality inspection, the present application provides an automatic chain performance inspection device.

[0006] The present application provides an automatic chain performance detection device that adopts the following technical solution: A chain performance automatic detection device comprises a base plate, two sprockets and a detection mechanism, wherein the sprocket is rotatably connected to the base plate, the detection mechanism is arranged on the base plate, the detection mechanism comprises a mounting plate, a displacement sensor and an abutment block, the mounting plate is fixed on the base plate, the displacement sensor comprises a stator and a mover, the mover is slidably connected to the stator, the stator is fixed on the mounting plate, the mover is connected to the abutment block, and the detection mechanism is arranged between the two sprockets.

[0007] By adopting the above technical solution, sprockets are arranged on the substrate so that the two sprockets can mesh with the chain and drive the chain to rotate. When the chain rotates, the detection mechanism detects the spacing between adjacent chain pins on the chain in turn. By arranging an abutment block on the displacement sensor so that the abutment block abuts against the chain pin of the chain, when the chain rotates through the sprocket, the abutment block drives the displacement sensor to extend and retract periodically. The user can check the amplitude of the reciprocating movement of the abutment block by receiving the electrical signal sent by the displacement sensor, and then can judge whether the installation position of the chain pin is skewed. The user can set the displacement sensor on the sprocket. The motor drives the sprocket to rotate at a fixed speed. When the moving speed of the chain is equal, the time consumed by the reciprocating movement of the abutment block can reflect the distance between two adjacent chain pins, which is convenient for users to check the production quality of the chain. When the accuracy of the displacement sensor is low, the displacement sensor has errors when checking each chain pin, and the displacement sensor has errors when detecting the position of each chain pin. By comparing the reciprocating movement cycle of the abutment block, the error of the displacement sensor can be eliminated. Even if the error of the detection mechanism is large after being used for a long time, the detection mechanism can still make accurate detection of the chain production quality.

[0008] Optionally, a slide groove is opened on the base plate, the slide groove passes through the base plate, a slide rod is arranged on the sprocket, the slide rod is inserted into the slide groove, a cam is fixed at one end of the slide rod, and a fixing nut is threadedly connected at the other end, the cam and the fixing nut are used to clamp the base plate, the end of the slide rod is rotatably connected to a rotating shaft, and the sprocket is installed on the rotating shaft.

[0009] By adopting the above technical solution, a sliding groove is opened on the base plate so that the sprocket can slide on the base plate through the sliding rod. After the user puts the chain on the two sprockets, the position of the sprocket on the base plate can be adjusted, so that the sprocket can abut against the chain and keep the chain taut. At this time, the detection mechanism can detect the chain production quality with higher accuracy.

[0010] Optionally, the sprocket is detachably connected to the rotating shaft.

[0011] By adopting the above technical solution, by making the sprocket and the rotating shaft detachably connected, the user can install sprockets of different specifications on the rotating shaft, thereby facilitating the user to perform quality inspection on chains of different specifications.

[0012] Optionally, a handle is detachably connected to the sprocket, and the handle is used to drive the sprocket to rotate.

[0013] By adopting the above technical solution, by providing a handle on the sprocket, the user can install the handle on the sprocket and shake the handle, thereby facilitating the user to manually drive the sprocket to rotate and facilitating detection.

[0014] Optionally, the length direction of the displacement sensor is perpendicular to the length direction of the slide groove where the sprocket is located.

[0015] By adopting the above technical solution, by making the displacement sensor perpendicular to the slide slot, the user can control the forward and reverse rotation of the sprocket, so that the chain can pass through the detection mechanism in the forward and reverse directions. The detection mechanism detects the chain twice to improve the detection accuracy. The chain can smoothly push the abutment block and drive the displacement sensor to extend and retract when rotating forward and reverse.

[0016] Optionally, a tensioning wheel is provided on the base plate, a slider is provided on the tensioning wheel, the slider is slidably connected in the slide groove, the tensioning wheel is rotatably connected to the slider, a spring is provided on the slider, an abutment plate is fixed on the base plate, one end of the spring is fixed on the abutment plate, and the other end is fixed on the slider, and the length direction of the spring is parallel to the length direction of the slide groove where the tensioning wheel is located.

[0017] By adopting the above technical solution, a tensioning wheel is arranged on the base plate, so that the tensioning wheel can slide to the side of the slide groove away from the sprocket through the spring. When the chain is mounted on the sprocket and the tensioning wheel, the tensioning wheel can keep the chain taut, so that the chain can always remain engaged with the sprocket. When the base plate is set horizontally, the sprocket can also remain tightly connected with the chain.

[0018] Optionally, a reset spring is sleeved on the displacement sensor, one end of the reset spring is fixed on the abutment block, and the other end is fixed on the displacement sensor.

[0019] By adopting the above technical solution, a reset spring is arranged on the displacement sensor so that the reset spring can push the abutment block, so that the displacement sensor maintains the longest length state, and the abutment block can be located in the middle of the chain and on the moving path of the chain pin, so that the detection mechanism can always stay connected with the chain and detect the position of the chain pin.

[0020] Optionally, two detection mechanisms are provided, and when the chain is installed on the sprocket, the two detection mechanisms are respectively located on the upper side and the lower side of the chain.

[0021] By adopting the above technical solution, two detection mechanisms are set on the substrate, and the two detection mechanisms are respectively located on both sides of the chain. When the chain moves, the two detection mechanisms detect the chain pins on the chain one by one in turn, thereby improving the accuracy of chain quality detection.

[0022] In summary, the beneficial technical effects of this application are: 1. By arranging sprockets on the substrate and setting detection mechanisms between the sprockets, the sprockets can drive the chain to pass through the detection mechanism. When the chain moves, the abutment block abuts against the chain pin of the chain, thereby causing the displacement sensor to move back and forth. By checking the movement amplitude and extension time of the displacement sensor, the user can know the spacing and position of the chain pins on the chain, thereby achieving the effect of chain production quality detection; 2. By opening a slide groove on the base plate, the sprocket is slidably connected to the base plate, so that the sprocket can slide in the slide groove. By adjusting the position of the sprocket, the user can keep the chain tight between the two sprockets, thereby improving the quality inspection accuracy when the detection mechanism detects the position of the chain pin; 3. By arranging a tension wheel on the base plate, the chain can be tightened and meshed with the sprocket and the tension wheel, so that the chain can remain in a state of being attached to the sprocket, reducing the probability of the chain detaching from the sprocket.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] The present application embodiment discloses a chain performance automatic detection device, referring to Figure 1 and Figure 2, including a base plate 1, a plurality of sprocket wheels 2, a tension wheel 3 and a detection mechanism 4. A slide groove 11 is provided on the base plate 1. The sprocket wheels 2 are rotatably connected to the same side of the base plate 1. A slider 31 is provided on the tension wheel 3. The tension wheel 3 is rotatably connected to the slider 31. The slider 31 is slidably connected in the slide groove 11. The user sets the chain 5 on the sprocket wheel 2 so that the tension wheel 3 abuts against the inner side of the chain 5, so that the sprocket wheel 2 and the tension wheel 3 can keep meshing with the chain 5. The user can make the chain 5 rotate on the base plate 1 by rotating the sprocket wheel 2. The detection mechanism 4 is installed on the base plate 1. The detection mechanism 4 is set on one side of the chain 5. When the chain 5 rotates on the base plate 1, the detection mechanism 4 can detect the spacing of the chain pins 52 on the chain 5 in sequence, so as to achieve the effect of detecting the production quality of the chain 5.

[0031] Reference Figure 1 and Figure 2 , a plurality of slide grooves 11 are arranged on the base plate 1, the length direction of the slide grooves 11 is a straight line, and the slide grooves 11 penetrate the base plate 1. The sprocket 2 is slidably connected in the slide groove 11, and there are two sprockets 2, and the length direction of the slide grooves 11 where the two sprockets 2 are located overlaps. A slide rod 21 is arranged on the sprocket 2, and the slide rod 21 is inserted into the slide groove 11. One end of the slide rod 21 is coaxially connected with a convex circle 211, and the other end is threadedly connected with a fixing nut 212. The fixing nut 212 and the convex circle 211 jointly clamp the base plate 1, so that the sprocket 2 can remain stationary at any position in the slide groove 11. A rotating shaft 22 is coaxially arranged on the slide rod 21, and the rotating shaft 22 is rotatably connected to the slide rod 21. The sprocket 2 is detachably connected to the rotating shaft 22, and the user can install sprockets 2 of different specifications on the rotating shaft 22, so that the detection mechanism 4 can detect chains 5 of different specifications. When the user puts the chain 5 on the sprocket 2, the user can adjust the position of the sprocket 2 so that the two sprockets 2 are engaged with the chain 5 and the chain 5 is tightened. The detection mechanism 4 is set between the two sprockets 2. The detection mechanism 4 detects the tensioned chain 5 to improve the detection accuracy.

[0032] Reference Figure 2 The slider 31 is provided with a spring 33, and the base plate 1 is fixedly connected with an abutment plate 32. One end of the spring 33 is fixed on the abutment plate 32, and the other end is fixed on the slider 31. The length direction of the spring 33 is parallel to the sliding direction of the slider 31. The spring 33 pushes the slider 31, so that the slider 31 is located at a side of the slide groove 11 away from the sprocket 2 in a natural state. When the chain 5 is sleeved on the sprocket 2 and the tension wheel 3, the tension wheel 3 abuts on the chain 5 through the spring 33, so that the chain 5 is kept in a taut state.

[0033] Reference Figure 3 and Figure 4The detection mechanism 4 includes a mounting plate 41, a displacement sensor 42, a reset spring 43 and an abutment block 44. The mounting plate 41 is fixed on the base plate 1. The displacement sensor 42 includes a stator and a mover. The mover is slidably connected to the stator. The stator is fixed on the mounting plate 41, and the abutment block 44 is fixed on the mover. The length direction of the displacement sensor 42 is perpendicular to the length direction of the slide groove 11 where the sprocket 2 is located. When the chain 5 rotates on the sprocket 2, the abutment block 44 is located between the chain plates 51 and abuts on the chain pin 52. When the chain 5 moves, the chain pin 52 drives the displacement sensor 42 to expand and contract, thereby causing the displacement sensor 42 to output an electrical signal. By receiving the electrical signal and checking the expansion and contraction range of the displacement sensor 42, the user can know whether the spacing between multiple chain pins 52 on the chain 5 meets the requirements. The reset spring 43 is sleeved on the displacement sensor 42, one end of the reset spring 43 is fixed on the abutment block 44, and the other end is fixed on the stator of the displacement sensor 42. The reset spring 43 is used to push the abutment block 44 so that the abutment block 44 remains in the position inserted into the chain 5, thereby enabling the abutment block 44 to maintain abutment with the chain 5.

[0034] Reference Figure 3 and Figure 4 There are two detection mechanisms 4, which are respectively arranged on the upper and lower sides of the chain 5. The abutment blocks 44 of the two detection mechanisms 4 are respectively located on the upper and lower sides of the chain 5 and abut against the chain 5, thereby detecting the spacing between the chain pins 52 on the chain 5 to improve the detection accuracy.

[0035] Reference Figure 5 A handle 23 is detachably connected to the sprocket 2, and two insertion rods 231 are installed at the end of the handle 23. Two through holes are provided on the sprocket 2, and the insertion rods 231 are used to be inserted into the through holes of the sprocket 2. The user can rotate the sprocket 2 through the handle 23, thereby making the chain 5 rotate on the sprocket 2, so that the detection mechanism 4 can detect the chain 5.

[0036] The implementation principle of the embodiment of the present application is: by arranging the sprocket 2 and the tensioning wheel 3 on the substrate 1, the chain 5 can be sleeved on the sprocket 2 and the tensioning wheel 3, so that the chain 5 is kept in a taut state and passes through one side of the detection mechanism 4. The detection mechanism 4 detects the distance between adjacent chain pins 52 on the chain 5 in turn, thereby achieving the effect of quickly detecting the production quality of the chain 5.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
