Description

Technical Field

[0001] This application relates to the field of springs, and particularly to an automatic spring height measuring device. Background Art

[0002] Currently, the measurement of spring height mostly relies on manual operation, using calipers or other measuring tools. This method is inefficient and vulnerable to human factors, making it difficult to guarantee measurement accuracy.

[0003] Existing spring height measurement techniques usually use mechanical calipers or electronic calipers for manual measurement. The disadvantages of these methods are slow measurement speed, large influence of human operation on accuracy, and easy fatigue of operators caused by long-term repeated measurement. Summary of the Utility Model

[0004] To improve the above problems, this application provides an automatic spring height measuring device.

[0005] An automatic spring height measuring device provided by this application adopts the following technical solutions:

[0006] An automatic spring height measuring device includes a frame. A plurality of transfer plates slide relative to each other on the frame. Springs are placed on the transfer plates. A transmission component for controlling the sliding of the transfer plates is provided on the frame. A first measuring plate slides relative to each other in the vertical direction on the frame. The first measuring plate is located above the transfer plates. A control component for controlling the sliding of the first measuring plate is provided on the frame.

[0007] By adopting the above technical solutions, an operator can place a spring on the transfer plate. The transfer plate can drive the spring to move through the transmission component. When the transfer plate drives the spring to move below the transfer plate, the control component drives the first measuring plate to move in the vertical direction. The first measuring plate moves to contact the spring on the transfer plate to measure the height of the spring, eliminating the need for manual measurement by the operator, with high measurement accuracy, saving manpower, and improving the measurement work efficiency.

[0008] Preferably, a second measuring plate slides relative to each other on one side of the frame and located at the side of the transfer plate. A pushing plate slides relative to each other on the side of the frame away from the second measuring plate and located at the side of the transfer plate. The sliding directions of the second measuring plate and the pushing plate are both perpendicular to the sliding direction of the transfer plate. The pushing plate slides closer to or away from the second measuring plate.

[0009] By adopting the above technical solutions, the pushing plate can slide closer to the second measuring plate and can slide to abut against the spring on the transfer plate to push the spring to contact the second measuring plate, thereby measuring the diameter of the spring.

[0010] Preferably, guide plates are fixedly connected to both sides of the transfer plate on the frame, and the guide plates are located on the side of the second measuring plate away from the first measuring plate.

[0011] By adopting the above technical solution, after the spring is placed on the transfer plate, when the transfer plate drives the spring to move between the two guide plates, the guide plates can limit the position of the spring, so that the spring is in a suitable position on the transfer plate, facilitating the measurement of the height and diameter of the spring.

[0012] Preferably, a plurality of pushing plates are slidably arranged on the frame, the sliding direction of the pushing plates is perpendicular to the sliding direction of the transfer plate, the pushing plates are located on the side of the first measuring plate away from the second measuring plate, and a blanking plate is fixedly connected to the frame on the side of the transfer plate away from the pushing plates.

[0013] By adopting the above technical solution, after the spring measurement is completed, according to the actual measurement result of the spring, the pushing plate slides to abut against the spring and pushes the spring out of the transfer plate, and the spring can slide down from the blanking plate to store springs of different sizes separately.

[0014] Preferably, the control assembly includes a control board, a control column, a first sensor, a mating column, a guide column, a support spring and a first cylinder. The control board is located above the first measuring plate, the control board and the frame are slidably connected, the control board and the first measuring plate are slidably connected. The control column is fixedly connected to the first measuring plate, one end of the control column away from the first measuring plate passes through the control board, and a control nut is threadedly connected to the end of the control column passing through the control board. The first sensor is installed on the control board, the mating column is fixedly connected to the first measuring plate, the guide column is slidably connected to the frame, one end of the guide column away from the frame passes through the control board and is fixedly connected to the first measuring plate, the support spring is sleeved on the guide column, one end of the support spring abuts against the first measuring plate, and the other end abuts against the control board. The first cylinder is installed on the frame, and the piston rod of the first cylinder is fixedly connected to the control board.

[0015] By adopting the above technical solution, when it is necessary to measure the height of the spring, the operator can drive the first cylinder, the piston rod of the first cylinder can drive the movement of the control board, the movement of the control board can drive the movement of the first measuring plate, so that the first measuring plate abuts against the top of the spring; after the first measuring plate abuts against the top of the spring, the control board continues to move downward, the movement of the control board can drive the movement of the first sensor, until the first sensor contacts the mating column, and at this time, the measurement of the spring height is completed.

[0016] Preferably, a limiting column is fixedly connected to the side of the control board facing the first measuring plate.

[0017] By adopting the above technical solution, after the first measuring plate abuts against the top end of the spring, the control plate continues to move downward, and the limiting column can limit the moving distance of the control plate, reducing the possibility that the moving distance of the control plate is too large and causing the first sensor to collide with the mating column and be damaged.

[0018] Preferably, the transmission assembly includes a first sprocket, a second sprocket, a chain and a motor. The first sprocket and the second sprocket are both rotatably connected to the frame. The first sprocket is located at one end of the frame, and the second sprocket is located at the other end of the frame. The chain is wound around the first sprocket and the second sprocket. The transmission plate is fixedly connected to the chain. The motor is installed on the frame, and the output shaft of the motor is fixedly connected to the rotating shaft of the first sprocket.

[0019] By adopting the above technical solution, the operator can drive the motor, so that the output shaft of the motor drives the rotation of the first sprocket, thereby driving the rotation of the chain. The rotation of the chain can drive the movement of the transmission plate, thereby driving the movement of the spring, facilitating the measurement of the height and diameter of the spring.

[0020] Preferably, a second cylinder is installed on the frame. A sleeve is fixedly connected to the piston rod of the second cylinder. The sleeve is fixedly connected to the second measuring plate. A second sensor is installed on the sleeve. A third cylinder is installed on the frame. The piston rod of the third cylinder is fixedly connected to the pushing plate.

[0021] By adopting the above technical solution, when it is necessary to measure the diameter of the spring, the operator can drive the third cylinder. The piston rod of the third cylinder can drive the movement of the pushing plate. The pushing plate can push the spring to abut against the second measuring plate. The second measuring plate moves under the abutting action of the spring. After moving a specific distance, the second sensor emits a signal, and at this time, the measurement of the spring diameter is completed. After the spring diameter detection is completed, the third cylinder drives the pushing plate to reset. The piston rod of the second cylinder drives the sleeve to move, and the sleeve drives the second measuring plate to move, so that the second measuring plate is reset, facilitating the subsequent measurement of the spring.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the settings of the transmission plate, the transmission assembly, the first measuring plate and the control assembly, the operator can place the spring on the transmission plate. The transmission plate can drive the spring to move through the transmission assembly. When the transmission plate drives the spring to move below the transmission plate, the control assembly drives the first measuring plate to move in the vertical direction.

[0024] 2. Through the arrangement of the guiding plates, after the spring is placed on the transfer plate, when the transfer plate drives the spring to move between the two guiding plates, the guiding plates can limit the position of the spring, enabling the spring to be in a suitable position on the transfer plate, which facilitates the measurement of the height and diameter of the spring.

Detailed Description of the Embodiment

[0029] The following is a further detailed description of the present application in conjunction with the attached Figures 1-3 drawings.

[0030] The embodiment of the present application discloses a spring automatic height measuring device. As Figure 1 shown, it includes a frame 1. A plurality of transfer plates 2 slide relative to each other on the frame 1, and the transfer plates 2 are for placing springs. A transmission component 3 for controlling the sliding of the transfer plates 2 is provided on the frame 1. The transmission component 3 includes a first sprocket 31, a second sprocket 32, a chain 33 and a motor 34. Both the first sprocket 31 and the second sprocket 32 are rotatably connected to the frame 1. The first sprocket 31 is located at one end of the frame 1, and the second sprocket 32 is located at the other end of the frame 1. The chain 33 is wound around the first sprocket 31 and the second sprocket 32, and the transfer plates 2 are fixedly connected to the chain 33. The motor 34 is fixedly installed on the frame 1, and the output shaft of the motor 34 is fixedly connected to the rotating shaft of the first sprocket 31. An operator can drive the motor 34. The output shaft of the motor 34 can drive the rotation of the first sprocket 31. The rotation of the first sprocket 31 can drive the rotation of the chain 33. The rotation of the chain 33 can drive the movement of the transfer plates 2. The transfer plates 2 can drive the movement of the springs, which facilitates the measurement of the height and diameter of the springs.

[0031] As Figure 1 and 2 shown, a first measuring plate 11 slides relatively vertically on the frame 1. The first measuring plate 11 is located above the transmission plate 2, and the first measuring plate 11 can slide to abut against the top end of the spring. A control assembly 4 for controlling the sliding of the first measuring plate 11 is provided on the frame 1. The control assembly 4 includes a control plate 41, a control column 42, a first sensor 43, a mating column 44, a guiding column 45, a supporting spring 46 and a first cylinder 47. The control plate 41 is located above the first measuring plate 11. The control plate 41 and the frame 1 slide relatively. The control plate 41 slides close to or away from the first measuring plate 11. The control column 42 is fixedly connected to the first measuring plate 11. The length direction of the control column 42 is the vertical direction. One end of the control column 42 away from the first measuring plate 11 passes through the control plate 41, and a control nut 421 is threadedly connected to the end of the control column 42 passing through the control plate 41. The first sensor 43 is a contact sensor. The first sensor 43 is installed on the control plate 41. The mating column 44 is fixedly connected to the first measuring plate 11. The mating column 44 is located below the first sensor 43. The guiding column 45 is slidably connected to the frame 1. One end of the guiding column 45 away from the frame 1 passes through the control plate 41 and is fixedly connected to the first measuring plate 11. The supporting spring 46 is sleeved on the guiding column 45. One end of the supporting spring 46 abuts against the first measuring plate 11, and the other end abuts against the control plate 41. In the natural state, the supporting spring 46 exerts a thrust on the control plate 41 to make the control plate 41 slide away from the first measuring plate 11. The first cylinder 47 is installed on the frame 1. The piston rod of the first cylinder 47 is fixedly connected to the control plate 41. A limiting column 411 is fixedly connected to the side of the control plate 41 facing the first measuring plate 11.

[0032] When the transmission plate 2 drives the spring to move below the first measuring plate 11, the piston rod of the first cylinder 47 drives the control plate 41 to move. The supporting spring 46 exerts a thrust on the control plate 41, and the control nut 421 can limit the movement of the control plate 41. Therefore, the control plate 41 and the first measuring plate 11 are relatively fixed. The movement of the control plate 41 can drive the movement of the first measuring plate 11, so that the first measuring plate 11 moves to abut against the top end of the spring. After the first measuring plate 11 abuts against the top end of the spring, the first cylinder 47 continues to drive the control plate 41 to move downward. The movement of the control plate 41 can drive the movement of the first sensor 43. The first sensor 43 can move to contact the mating column 44. At this time, the measurement of the spring height is completed. The limiting column 411 can limit the downward movement of the control plate 41, reducing the possibility that the first sensor 43 is damaged due to the collision between the first sensor 43 and the mating column 44 when the control plate 41 drives the first sensor 43 to move.

[0033] As Figure 1 and 3As shown, a second measuring plate 12 is relatively slidable on the frame 1 and located on one side of the transmission plate 2, a second cylinder 17 is fixedly installed on the frame 1, a sleeve 171 is fixedly connected to the piston rod of the second cylinder 17, and the sleeve 171 is fixedly connected to the second measuring plate 12; a second sensor 172 is installed on the sleeve 171, and the second sensor 172 is a displacement sensor. A push plate 13 is relatively slidable on the frame 1 and located on the side of the transmission plate 2 away from the second measuring plate 12, the sliding directions of the second measuring plate 12 and the push plate 13 are both perpendicular to the sliding direction of the transmission plate 2, and the push plate 13 slides close to or away from the second measuring plate 12. A third cylinder 18 is fixedly installed on the frame 1, and the piston rod of the third cylinder 18 is fixedly connected to the push plate 13. When the transmission plate 2 drives the spring to move between the second measuring plate 12 and the push plate 13, the piston rod of the third cylinder 18 can drive the push plate 13 to move, and the push plate 13 can apply force to the spring, so that the spring moves to abut against the second measuring plate 12, and the second measuring plate 12 moves away from the transmission plate 2 under the action of the spring. When the second measuring plate 12 moves a specific distance, the second sensor 172 sends a signal, and the spring diameter measurement is completed at this time. After the spring diameter detection is completed, the third cylinder 18 drives the push plate 13 to reset, the piston rod of the second cylinder 17 drives the sleeve 171 to move, and the sleeve 171 drives the second measuring plate 12 to reset, which is convenient for the subsequent spring diameter measurement.

[0034] like Figure 3 As shown, guide plates 14 are fixedly connected to the frame 1 and located on both sides of the transmission plate 2. The guide plates 14 are located on the side of the second measuring plate 12 that is away from the traveling direction of the spring. When the spring is placed on the transmission plate 2 and transported between the two guide plates 14, the guide plates 14 can limit the position of the spring so that the spring is located near the center of the transmission plate 2, which is convenient for measuring the height and diameter of the spring.

[0035] like Figure 1 As shown, a plurality of push plates 15 are provided on the frame 1 along the direction of the spring travel, and the plurality of push plates 15 and the frame 1 slide relative to each other. An installation box 19 is fixedly installed on the frame 1, and a cylinder for controlling the sliding of the push plates 15 is provided in the installation box 19; a blanking plate 16 is fixedly connected to the frame 1 and located on the side of the transmission plate 2 away from the push plate 15. After the height and diameter measurement of the spring is completed, springs of different sizes need to be classified. When the transmission plate 2 drives the spring to move between the push plate 15 and the blanking plate 16, the cylinder drives the push plate 15 to slide according to the actual measurement result of the spring, and the push plate 15 pushes the springs of the same size out of the transmission plate 2 and slides off the blanking plate 16, so as to facilitate the classification and storage of springs of different sizes.

[0036] The implementation principle of a spring automatic height measuring device in the embodiment of the present application is:

[0037] The operator drives the motor 34. The output shaft of the motor 34 drives the rotation of the first sprocket 31, thereby driving the rotation of the chain 33. The chain 33 can drive the movement of the transfer plate 2, and the transfer plate 2 can drive the spring to move. When the spring passes between the two guide plates 14, the guide plates 14 can limit the position of the spring, so that the spring is located at a position close to the center on the transfer plate 2. Then the transfer plate 2 continues to drive the spring to move. When the spring moves between the second measuring plate 12 and the pushing plate 13, the third cylinder 18 drives the pushing plate 13 to move, and the pushing plate 13 pushes the spring to abut against the second measuring plate 12. When the second measuring plate 12 moves a specific distance, the second sensor 172 emits a signal, and at this time, the measurement of the spring diameter is completed. After that, when the transfer plate 2 drives the spring to move below the first measuring plate 11, the first cylinder 47 drives the movement of the control plate 41, and the control plate 41 drives the first measuring plate 11 to abut against the top of the spring. When the first sensor 43 contacts the mating post 44, the first sensor 43 emits a signal, and at this time, the measurement of the spring height is completed. Finally, when the transfer plate 2 drives the spring to move between the pushing plate 15 and the blanking plate 16, according to the actual measurement result of the spring, the cylinder drives the pushing plate 15 to slide, and the pushing plate 15 pushes the springs of the same size out of the transfer plate 2 and slides off the blanking plate 16, which is convenient for storing springs of different sizes separately.

[0038] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
