Description

Technical Field

[0001] This utility model relates to the field of shaft turning technology, specifically to a small automatic shaft turning machine. Background Technology

[0002] refer to Figure 1 As shown, a CNC lathe processes a type of shaft, which includes a main shaft and a secondary shaft. The diameter of the main shaft is larger than that of the secondary shaft. After being processed by the CNC lathe, several shafts are stacked together. When needed for later use, the shafts need to be manually arranged neatly before further processing and assembly. The shafts are all slender structures, and it is easy to make mistakes in orientation when arranging them manually. Although there are quality control personnel, manual arrangement is slow and has a high probability of errors, resulting in a heavy workload for the quality control personnel due to the large number of incorrectly arranged shafts. Summary of the Invention

[0003] The purpose of this invention is to provide a small automatic shaft turning machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a small automatic shaft turning machine, including a mounting frame on which a belt conveyor is mounted. From top to bottom, a holding device, a transport component, and a turning mechanism are sequentially arranged on the upper side of the mounting frame. Several shafts are placed inside the holding device. The transport component transports the shafts inside the holding device one by one into the turning mechanism. The turning mechanism turns shafts that are not aligned correctly. The turning mechanism includes a turning plate with a through groove. A guide block is fixedly mounted on the lower side of the turning plate. A guide cavity is formed inside the guide block, with its upper side connected to the through groove. One side of the guide cavity extends through the side wall of the guide block. A fixing frame is fixed to one side of the guide block, and an inclined plate is fixed to the fixing frame. The inclined plate is tilted and located below the guide cavity. A channel is formed between the lower end of the inclined plate and the fixing frame, through which the shaft falls onto the belt conveyor.

[0005] As a further improvement to this technical solution, the transport component includes a rotating roller rotatably mounted on the upper side of the mounting frame via a bracket. The rotating roller is located on the upper side of the turning plate, and a drive motor for driving the rotating roller to rotate is provided on one side of the rotating roller. The drive motor is fixedly mounted on the upper side of the mounting frame.

[0006] As a further improvement to this technical solution, the holding device includes two vertically arranged side plates, and a rear guide plate and a front guide plate are fixed on both sides between the two side plates respectively. The lower ends of the rear guide plate and the front guide plate are inclined downward towards each other, and the lower end of the front guide plate is located above the lower end of the rear guide plate.

[0007] As a further improvement to this technical solution, the lower end of the rear guide plate is located on the upper side of the rotating roller and there is a gap between it and the rotating roller. The shaft is placed in the space enclosed between the two side plates, the rear guide plate and the front guide plate. Several shaft placement slots that are adapted to the shape of the shaft are arranged in an annular array on the side wall of the rotating roller. The shaft falls into the inside of the shaft placement slot through the rear guide plate and the front guide plate.

[0008] As a further improvement to this technical solution, the turning mechanism also includes a receiving frame fixed on the upper side of the turning plate. The upper side of the receiving frame is provided with an arc-shaped groove, the rotating roller rotates in the arc-shaped groove, and there is a gap between the turning plate and the rotating roller.

[0009] As a further improvement to this technical solution, a limiting block and a main shaft stop are fixed on one side of each end of the through groove. The distance between the limiting block and the other side of the through groove is greater than the diameter of the main shaft rod, and the distance between the main shaft stop and the other side of the through groove is greater than the diameter of the secondary shaft rod and less than the diameter of the main shaft rod.

[0010] As a further improvement to this technical solution, the bottom of the guide cavity is arc-shaped, wherein the end of the bottom of the guide cavity near the limiting block is higher than the other end, and the distance between the upper side of the turning plate and the bottom of the guide cavity is greater than the length of the shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this small automatic shaft turning machine, the rotation of the rotating roller moves each shaft to the upper side of the turning plate. When the shaft moves directly below the rotating roller, it enters the through groove. If the shaft is in the correct orientation, the main shaft passes through the limiting block and the secondary shaft passes through the main shaft stop. If the shaft is in the wrong orientation, the main shaft stop and the main shaft contact each other, preventing the main shaft from moving downwards, while the secondary shaft moves downwards from the limiting block. The shaft then rotates and, after being vertically aligned, separates from the main shaft stop. The inertia of the shaft's rotation and the guidance of the arc-shaped bottom of the guide cavity cause the shaft to rotate 180 degrees. Then, guided by the inclined plate, the shaft falls onto the belt conveyor. This method eliminates the hassle of manual placement, reduces the error rate of shaft placement, and reduces the workload of quality inspection personnel. Attached Figure Description

Example

[0016] Please see Figures 1-7As shown, this embodiment provides a small automatic shaft turning machine, including a mounting frame 1. A belt conveyor 6 is mounted on the mounting frame 1, supporting the belt conveyor 6. The belt conveyor 6 includes an annular synchronous conveyor belt and rollers that drive the synchronous conveyor belt. The rollers are driven by a motor. On the upper side of the mounting frame 1, from top to bottom, are arranged a holding device 3, a transport component 2, and a turning mechanism 4. Several shafts are placed inside the holding device 3, and the orientation of these shafts is random, with some correctly oriented and some incorrectly oriented. The transport component 2 is used to transport the shafts inside the holding device 3 one by one to the turning mechanism 4. The turning mechanism 4 is used to turn the shafts with incorrect orientation. In use, the operator puts a large number of shafts into the holding device 3. Inside, transport component 2 conveys several shafts downwards one by one, causing them to fall into the turning mechanism 4. Shafts in the correct orientation are guided directly by the turning mechanism 4 to fall onto the belt conveyor 6, which then transports them away. Shafts in the wrong orientation, after entering the turning mechanism 4, are turned around to the correct orientation before falling onto the belt conveyor 6. Quality inspectors then observe the shafts placed on the belt conveyor 6 to further ensure their correct orientation. This method eliminates the hassle of manual placement, reduces the probability of incorrect shaft orientation, decreases the workload of workers, and speeds up the placement process.

[0017] The transport component 2 includes a rotating roller 22 rotatably mounted on the upper side of the mounting frame 1 via a bracket. A drive motor 21 for driving the rotating roller 22 is provided on one side of the rotating roller 22. The rotating shafts of the rotating roller 22 and the drive motor 21 are coaxially arranged. The drive motor 21 is fixedly mounted on the upper side of the mounting frame 1 via a bracket. The holding device 3 includes two vertically arranged side plates 31. A rear guide plate 32 and a front guide plate 33 are respectively fixed on both sides of the two side plates 31. The lower ends of the rear guide plate 32 and the front guide plate 33 are inclined downwards towards each other. A gap is left between the lower sides of the rear guide plate 32 and the front guide plate 33 for the passage of a shaft. The two side plates 31, the rear guide plate 32, and the front guide plate 33 form a shape that gradually tapers at the lower side. The lower end of the front guide plate 33 is located above the lower end of the rear guide plate 32. At the same time, the lower end of the rear guide plate 32 is located above the rotating roller 22. The shaft is placed on the upper side of the rotating roller 22 with a gap between it and the rotating roller 22. The shaft is placed in the space enclosed by the two side plates 31, the rear guide plate 32, and the front guide plate 33. At this time, the inclined rear guide plate 32 and the front guide plate 33 guide the shaft downward. The shaft falls from the gap between the rear guide plate 32 and the front guide plate 33 to the upper side of the rotating roller 22. At this time, the rotating roller 22 supports several shafts. At the same time, a protective plate 34 is fixed between the two side plates 31 on the lower side of the front guide plate 33. The protective plate 34 prevents the shaft from falling out. There is also a gap between the protective plate 34 and the rotating roller 22. The gaps between the rear guide plate 32 and the protective plate 34 and the rotating roller 22 are the same and the distance is less than the diameter of the main shaft. The protective plate 34, the front guide plate 33, and the rotating roller 22 combine to form a space for placing the shaft, so the shaft will not fall out from the gap.

[0018] A support plate 5 is fixed on the upper side of the mounting frame 1. The upper side of the support plate 5 is fixedly connected to the support plate and the rear guide plate 32, so that the holding device 3 can be stably fixed on the upper side of the transport component 2.

[0019] Several shaft placement slots 23, which are adapted to the shape of the shaft, are arranged in a ring array on the side wall of the rotating roller 22. The shaft falls into the shaft placement slot 23 through the gap between the rear guide plate 32 and the front guide plate 33. The shaft that falls into the shaft placement slot 23 can be removed from the underside of the holding device 3 through the gap between the protective plate 34 and the rotating roller 22. When the shaft of the drive motor 21 rotates, it drives the rotating roller 22 to rotate on the underside of the holding device 3. During the rotation of the rotating roller 22, the shaft that has entered the shaft placement slot 23 is conveyed downward so that the shaft can fall onto the turning mechanism 4.

[0020] A limiting plate 35 is vertically arranged between the rear guide plate 32 and the front guide plate 33. The two sides of the limiting plate 35 slide in contact with the side walls of the rear guide plate 32 and the front guide plate 33, respectively. The lower side of the limiting plate 35 passes through the gap between the rear guide plate 32 and the front guide plate 33 and slides in contact with the protective plate 34. A gap of the same size as the gap between the rear guide plate 32 and the rotating roller 22 is left between the bottom of the limiting plate 35 and the rotating roller 22. The limiting plate 35 divides the space between the two side plates 31 into a placement cavity and a control cavity. Two sliding rods 37 are fixed on the side of the limiting plate 35 located in the control cavity, and a rotatable... The lead screw 36 and two slide bars 37 have one end that slides through the side wall of the side plate 31 and is fixed with a connecting bar. One end of the lead screw 36 passes through the side plate 31 and is threadedly connected to a fixing plate. The fixing plate and the lead screw 36 are threadedly connected. One end of the lead screw 36 is rotatably mounted on the connecting bar and is fixed with a handwheel. The user can drive the lead screw 36 to rotate by rotating the handwheel. The rotating lead screw 36 can drive the limiting plate 35 to move between the two side plates 31 through the threaded connection between it and the fixing plate. The moving limiting plate 35 can adjust the size of the placement cavity so that the placement cavity can be adapted to shafts of different lengths.

[0021] The turning mechanism 4 includes a turning plate 41 with a through groove 43. A guide block 44 is fixedly installed on the lower side of the turning plate 41. The bottom of the guide block 44 is fixed to the mounting frame 1 by a connecting block. A guide cavity 441 is provided inside the guide block 44. The upper side of the guide cavity 441 is connected to the through groove 43. One side of the guide cavity 441 penetrates the side wall of the guide block 44. A fixing frame 45 is fixed on one side of the guide block 44. The lower end of the fixing frame 45 is close to the belt conveyor 6. An inclined plate 46 is fixed on the fixing frame 45. The inclined plate 46 is inclined and the inclined plate is inclined to the side. 46 is located below the guide cavity 441. The inclined plate 46 forms a channel between its lower end and the fixed frame 45. The shaft falls onto the belt conveyor 6 through the channel. To ensure that the shaft does not roll due to inertia when it falls onto the belt conveyor 6, a vertically arranged guide plate is fixed below the inclined plate 46. The guide plate and the limiting plate 35 form the same space as the channel. The shaft falls onto the belt conveyor 6 through the channel and this space. This space restricts the position of the shaft, allowing it to fall accurately onto the belt conveyor 6.

[0022] The turning mechanism 4 also includes a receiving frame 42 fixed to the upper side of the turning plate 41. The rotating roller 22 is located on the upper side of the turning plate 41, and the through groove 43 is located directly below the bottom of the rotating roller 22. The receiving frame 42 is located on one side of the rotating roller 22, and an arc-shaped groove is opened on the upper side of the receiving frame 42. The rotating roller 22 rotates in the arc-shaped groove, and there is a gap between the turning plate 41 and the rotating roller 22. The distance of this gap is the same as the distance between the front guide plate 33 and the rotating roller 22. One end of the receiving frame 42 extends to a position slightly above the middle of the rotating roller 22 in the vertical direction. During the rotation of the rotating roller 22... The receiving frame 42 blocks the shaft placed in the shaft placement groove 23 to prevent the shaft from falling out of the groove 23. The other end of the receiving frame 42 extends to the bottom of the rotating roller 22, so that one end of the receiving frame 42 and the side wall of the through groove 43 are on the same vertical plane. At the same time, a stop bar 47 is provided on the other side of the through groove 43 and fixed to the upper side wall of the turning plate 41. The gap between the upper side of the stop bar 47 and the rotating roller 22 is the same as the gap between the receiving frame 42 and the rotating roller 22. The stop bar 47 blocks the shaft, ensuring that the shaft can fall accurately into the through groove 43.

[0023] A limiting block 431 and a main shaft stop block 432 are fixed on one side of each end of the through groove 43. The limiting block 431 is located in the through groove 43 away from the fixed frame 45, and the main shaft stop block 432 is located in the through groove 43 close to the fixed frame 45. Both the limiting block 431 and the main shaft stop block 432 are fixed on the side of the through groove 43 close to the stop bar 47, and the upper sides of the limiting block 431 and the main shaft stop block 432 are inclined downwards in the direction away from the stop bar 47. The distance between the limiting block 431 and the other side of the through groove 43 is greater than the diameter of the main shaft rod, and the distance between the main shaft stop block 432 and the other side of the through groove 43 is greater than the diameter of the secondary shaft rod but less than the diameter of the main shaft rod. When the shaft rod falls off the rotating roller 22... Afterwards, the limiting block 431 and the main spindle stop 432 contact both ends of the shaft. Then, the inclined limiting block 431 and the main spindle stop 432 guide the shaft towards the receiving frame 42. When the main shaft is closer to the limiting block 431 and the secondary shaft is closer to the main spindle stop 432, the shaft is in the correct direction and falls through the gap between the limiting block 431 and the main spindle stop 432. If the main shaft is closer to the main spindle stop 432 and the secondary shaft is closer to the limiting block 431, the main shaft cannot pass through the main spindle stop 432 because the gap between the main spindle stop 432 and the through groove 43 is smaller than the diameter of the main shaft. The limiting block 431 will not block the secondary shaft. (Reference) Figure 7The content shown by the dotted line is as follows: At this time, the secondary shaft will flip downwards, but because the main shaft stop 432 blocks the shaft, the main shaft will not flip downwards. As the secondary shaft rotates, the shaft gradually becomes vertical. During the vertical rotation of the shaft, the shaft and the main shaft stop 432 separate, and the shaft falls downwards. One end of the main shaft will move towards the limiting block 431 due to inertia, while one end of the secondary shaft will continue to move away from the limiting block 431 due to inertia. Due to the center of gravity and the trend of movement, the shaft will naturally flip 180 degrees during the fall. After the shaft rotates 90 degrees, the shaft contacts the bottom of the guide cavity 441, and then the shaft is removed from the guide cavity 441. The shaft is then turned around by the turning mechanism 4 so that the shaft coming out of the turning mechanism 4 is in the same direction, so as to facilitate the subsequent processing of the shaft.

[0024] To further improve the shaft turning effect, the bottom of the guide cavity 441 is made arc-shaped, with one end of the bottom of the guide cavity 441 closer to the limiting block 431 being higher than the other end. During the shaft turning process, the arc-shaped bottom of the guide cavity 441 can guide one end of the shaft away from the limiting block 431, further facilitating the shaft turning effect. At the same time, the distance between the upper side of the turning plate 41 and the bottom of the guide cavity 441 is greater than the length of the shaft, thereby providing sufficient turning space for the shaft.

[0025] This solution uses the rotation of the rotating roller 22 to move each shaft to the upper side of the turning plate 41. When the shaft moves directly below the rotating roller 22, it enters the through groove 43. If the shaft is in the correct orientation, the main shaft passes through the side of the limiting block 431, and the secondary shaft passes through the side of the main shaft stop 432. If the shaft is in the wrong orientation, the main shaft stop 432 contacts the main shaft, preventing the main shaft from moving downwards, while the secondary shaft moves downwards from the side of the limiting block 431. At this point, the shaft rotates, and after the shaft is vertically positioned, it separates from the main shaft stop 432. The rotational inertia of the shaft and the guidance of the arc-shaped bottom of the guide cavity 441 cause the shaft to rotate 180 degrees. Then, with the guidance of the inclined plate 46, the shaft falls onto the belt conveyor 6. This method eliminates the trouble of manual placement, reduces the error rate of shaft placement, and reduces the workload of quality inspection personnel.
