Description

Technical Field

[0001] This utility model relates to the field of steps, and in particular to an automatic feeding and inspection machine and processing system for step shafts. Background Technology

[0002] A shaft is an important mechanical component used to transmit rotational force between two objects, connecting or supporting them. Stepped shafts are one type of shaft with wide applications. When manufacturing stepped shafts (such as in external cylindrical grinding), the shafts first need to be fed and transported. For example, Chinese invention patent CN103008781B discloses an automatic feeding and cutting machine for stepped shafts. Because the outer diameters of the two ends of the stepped shaft are different, manual intervention is usually required to align the shafts when they are placed on the conveyor line to ensure smooth processing. With the gradual development of automation, roller feeding or vibratory feeding of shaft products has achieved more convenient and faster automatic feeding. However, stepped shafts, due to their specific orientation (different outer diameters at both ends), present a significant problem when the shafts enter the hopper with random orientations at both ends. This means that the orientations of the large and small ends cannot be aligned during automatic feeding and processing on the machine tool, leading to incorrect processing and still requiring manual intervention. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic feeding and inspection machine and processing system for stepped shafts. While achieving automatic feeding, the system automatically adjusts the direction of the large and small ends of the stepped shaft according to a preset direction, so that the direction of the stepped shaft entering the machine tool meets the processing requirements. This eliminates the need for manual intervention and achieves a high degree of automation.

[0004] The technical solution to achieve the purpose of this utility model is:

[0005] An automatic feeding and inspection machine for stepped shafts includes a hopper for batch storage of stepped shafts, wherein the hopper is equipped with a lifting device for conveying the stepped shafts upwards; an inspection table with a rotary drive device, the output end of which is fixedly connected to a worktable for storing individual stepped shafts; a conveying mechanism connected between the conveying end of the lifting device and the inspection table for conveying the lifted stepped shafts to one end of the inspection table; and a pushing mechanism symmetrically distributed on both sides of the conveying mechanism along the conveying direction, wherein the pushing mechanism has a sensor switch connected to the rotary drive device for detecting the direction of the stepped shafts; the pushing mechanism is adapted to push the stepped shafts on the conveying mechanism onto the worktable; and the rotary drive device is adapted to rotate the worktable according to the detection result of the sensor switch to align the directions of the stepped shafts on the worktable.

[0006] Furthermore, the inner wall of the hopper is provided with multiple stepped blocks of increasing height at equal intervals on the side near the conveying mechanism. The stepped blocks away from the conveying mechanism are flush with the bottom of the hopper. The lifting device includes a fixedly installed lifting cylinder and multiple sliders whose bottoms are fixedly connected to the piston rod ends of the lifting cylinder. The sliders are respectively fitted between adjacent stepped blocks, and their tops are aligned with the stepped blocks on the side away from the conveying device, forming multiple sets of downwardly inclined lifting platforms.

[0007] Furthermore, the angle between the lifting platform and the step block near the conveying mechanism is 60°.

[0008] Furthermore, the workbench is provided with a V-shaped groove, which is parallel to the conveying direction of the conveying mechanism and extends horizontally through the detection table at both ends.

[0009] Furthermore, the included angle between the two inner walls of the strip groove is 120±10°.

[0010] Furthermore, one side of the workbench is provided with a limiting post fixed to the testing table, and the other side is provided with a first push plate that can move along the axial direction of the step shaft. The end of the step shaft contacts the limiting post through the push of the first push plate.

[0011] Furthermore, a horizontally arranged first cylinder is fixedly mounted at the bottom of the testing platform, and the first push plate is vertically fixed to the piston rod of the first cylinder.

[0012] Furthermore, the pushing mechanism includes a second cylinder fixedly mounted on the conveying mechanism. The piston rod of the second cylinder is arranged perpendicular to the conveying direction in the horizontal direction and is vertically fixedly connected to a second push plate.

[0013] Furthermore, a detection head is fixedly mounted on the detection table and located above the step shaft on the same side of the first push plate. The rotation drive device is a planar rotary cylinder. The worktable is moved upward by the planar rotary cylinder to overlap with the detection head in the longitudinal direction. The detection head is used to detect the distance between the end of the step shaft and the detection head.

[0014] A machining system for stepped shafts includes an automatic feeding and inspection machine as described above.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] (1) This utility model adds a pushing mechanism, an induction switch and a rotatable worktable to the end of the conveying mechanism away from the hopper. The induction switch detects the direction of the step shaft on the conveying mechanism. If the direction is consistent with the processing direction, the pushing mechanism pushes the material directly onto the worktable, waiting for the subsequent process to transfer. If the direction is inconsistent with the processing direction, the direction is adjusted by rotating the worktable after the step shaft is pushed onto the worktable, thereby meeting the processing direction requirements. No manual intervention is required, and the degree of automation is high.

[0017] (2) This utility model adopts a stepped lifting device to deliver the stepped shaft at the bottom of the hopper to the conveying mechanism at the top. The structure is simple and can ensure that the axial direction of each stepped shaft is consistent with the conveying direction, which facilitates subsequent feeding operations.

[0018] (3) By controlling the tilt angle of the lifting platform, this utility model facilitates the step shaft to roll down when it is transferred to a higher lifting platform.

[0019] (4) By setting a V-shaped groove, this utility model ensures that the stepped shaft can be fixed by the two side walls of the groove when it is pushed onto the worktable, thus preventing it from rolling and falling.

[0020] (5) This utility model limits the included angle between the inner walls of the strip groove to about 120°, which can not only achieve the fixing effect of the stepped shaft, but also has a larger opening, which can meet the use of stepped shafts with more outer diameters.

[0021] (6) By setting a limiting post and a first push plate, after the stepped shaft is pushed onto the worktable, the first push plate pushes the end of the stepped shaft to contact the limiting post, thereby ensuring that the position of each stepped shaft along the axial direction is fixed, thereby improving the positional accuracy and facilitating the transfer of subsequent processes.

[0022] (7) This utility model uses a cylinder structure to drive a push plate structure to achieve short-distance translation of the step axis. The structure is simple and the action response is fast.

[0023] (8) By adding a detection head, when the step shaft rises to a specific position under the action of the worktable, the distance between the detection head and the corresponding end of the step shaft is measured by the detection head. Since the distance between the limit post and the detection head is constant, the axial dimension of the step shaft is indirectly detected, realizing automatic quality inspection of the length of the step shaft, saving manual operation and ensuring product quality.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] (Example 1)

[0032] A machining system for stepped shafts, used for machining shaft-type parts, including, for example... Figures 1 to 3 The automatic feeding and inspection machine shown is used to deliver stacked stepped shafts one by one to the subsequent process of the processing system, ensuring that the orientation of each stepped shaft is consistent. The automatic feeding and inspection machine for stepped shafts includes a hopper 1, an inspection table 2, a conveying mechanism 3, and a pushing mechanism 4. The hopper 1 is used to store stepped shafts in batches, and it is equipped with a lifting device 5 for conveying the stepped shafts in the hopper 1 upwards. The inspection table 2 is equipped with a rotary drive device 6, and the output end of the rotary drive device 6 is fixedly connected to a worktable 7 for storing individual stepped shafts. The conveying mechanism 3 is connected between the conveying end of the lifting device 5 and the inspection table 2, and is used to transport the lifted stepped shafts to one end of the inspection table 2. The pushing mechanism 4 and the detection table 2 are symmetrically distributed on both sides of the conveying mechanism 3 along the conveying direction. The side of the pushing mechanism 3 is equipped with an inductive switch 8 that is signal-connected to the rotary drive device 6. The inductive switch 8 can be an existing proximity switch. The direction of the step shaft is detected by the inductive switch 8. When the direction is opposite to the preset direction, the pushing mechanism 3 pushes the step shaft on the conveying mechanism 3 to the worktable 7. Then, the rotary drive device 6 drives the worktable 7 to rotate so that the direction of the step shaft on the worktable 7 is consistent with the setting, thereby meeting the processing direction requirements. No manual intervention is required, and the degree of automation is high.

[0033] Specifically, the inner wall of the hopper 1 has multiple stepped blocks 1-1 of increasing height arranged parallel and at equal intervals on the side near the conveying mechanism 3, with the stepped blocks 1-1 furthest from the conveying mechanism 3 flush with the bottom of the hopper 1. The lifting device 5 includes a fixedly mounted lifting cylinder 5-1 and sliders 5-2, the same number as the stepped blocks 1-1, each with its bottom fixedly connected to the piston rod end of the lifting cylinder 5-1. Multiple sliders 5-2 are respectively fitted between adjacent stepped blocks 1-1, and their tops are respectively aligned with the adjacent stepped block 1-1 on the left, forming multiple sets of downwardly inclined lifting platforms. The lifting cylinder 5-1 drives the sliders 5-2 to move up and down, thereby progressively conveying the stepped shaft at the bottom of the hopper 1 to the highest lifting platform. The angle between each lifting platform and the adjacent stepped block on the right is 60°, facilitating the step shaft to roll off when conveyed to a higher lifting platform.

[0034] The conveying mechanism 3 uses an existing belt conveyor. Its input end is connected to the top lifting platform of the lifting device 5 and is flush with the top right side of the lifting platform, so that the step shaft on it naturally rolls down to the conveying plane of the conveying mechanism 3.

[0035] The pushing mechanism 4 includes a second cylinder 4-1 fixedly mounted on the conveying mechanism 3. The piston rod of the second cylinder 4-1 is arranged horizontally perpendicular to the conveying direction and is vertically fixedly connected to a second push plate 4-2. The second cylinder 4-1 pushes the stepped shaft at the end of the conveying mechanism, causing the stepped shaft to move horizontally onto the worktable 7 on the other side of the pushing mechanism 4.

[0036] The worktable 7 is disc-shaped and embedded in the inspection table 2. Its upper surface is flush with the upper surface of the inspection table 2. It has a V-shaped groove 7-1 on its surface, which is parallel to the conveying direction of the conveying mechanism 3 and extends horizontally through the inspection table 2 at both ends. This ensures that the stepped shaft is fixed by the two side walls of the groove 7-1 when pushed onto the worktable 7, preventing it from rolling off. The included angle between the two inner walls of the groove 7-1 is 120±10°, which not only secures the stepped shaft but also provides a large opening to accommodate stepped shafts with a wider range of outer diameters.

[0037] The right side of the workbench 7 is equipped with a limiting post 9 fixed to the inspection table 2, and the other side is equipped with a first cylinder 10 fixed to the bottom of the inspection table 2. The piston rod of the first cylinder 10 is horizontally arranged, parallel to the conveying direction, and vertically fixed to a first push plate 11. By moving the first push plate 11 along the axial direction of the stepped shaft, the stepped shaft in the strip groove 7-1 is pushed towards the limiting post 9, so that the end of the stepped shaft contacts the limiting post 9, thereby ensuring that the position of each stepped shaft is fixed along the axial direction, thereby improving the positional accuracy and facilitating the transfer of subsequent processes.

[0038] On the same side of the first push plate 11, a detection head 12 is fixedly mounted on the detection table 2 and located above the step shaft. The rotary drive device 6 adopts a vertically upward-mounted planar rotary cylinder, which can realize both rotational movement to ensure the rotation of the worktable 7 and lifting movement. The worktable 7 is moved upward by the planar rotary cylinder until it overlaps with the detection head 12 longitudinally. The detection head uses an existing distance measuring sensor. When the step shaft rises to a specific position under the action of the worktable 7, the distance between the detection head 12 and the corresponding end of the step shaft is measured by the detection head 12. Since the distance between the limiting post 9 and the detection head 12 is constant, the axial dimension of the step shaft is indirectly detected, realizing automatic quality inspection of the length of the step shaft, eliminating manual operation and ensuring product quality.

[0039] This invention adds a pushing mechanism 4, an induction switch 8, and a rotatable worktable 7 to the end of the conveying mechanism 3 away from the hopper 1. The induction switch 8 detects the direction of the stepped shaft on the conveying mechanism 3. If the direction is consistent with the processing direction, it is directly pushed onto the worktable 7 by the pushing mechanism 4, waiting for the subsequent process to transfer. If the direction is inconsistent with the processing direction, the direction is adjusted by rotating the worktable 7 after the stepped shaft is pushed onto it, thereby meeting the processing direction requirements. No manual intervention is required, and the degree of automation is high.

[0040] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
