Description

Technical Field

[0001] This utility model relates to the field of shaft parts processing, specifically a shaft parts feeding device. Background Technology

[0002] With the rapid increase in the level of automation in the manufacturing industry, there are more and more devices used in the machining industry to assist in loading and unloading. When processing shaft parts such as motor rotor shafts, they are automatically gripped by robotic arms. Before the robotic arms can grip them, the shaft parts need to be placed in a certain direction and position to be successfully gripped. At this time, a loading device is needed to realize the automatic loading of shaft parts.

[0003] According to Chinese Patent No. CN216996498U, a long shaft part feeding device for CNC machine tools is disclosed. This utility model can automatically feed materials by designing a material storage structure and a pushing structure, and by cooperating with an external robotic arm. Before use, the materials only need to be stored in the storage structure in advance. This design can greatly save manpower during feeding.

[0004] Regarding the aforementioned disclosed patent content, by setting up a distributor with a distribution groove on the distributor, the shaft can fall from the material box into the distribution groove on the distributor. Then, by rotating the distributor, the shaft in the distribution groove can rotate and fall downward in an orderly manner. However, the shaft in the material box is difficult to fall accurately into the distribution groove, which may cause the shaft to fall onto the distributor. This makes it difficult for the shaft to rotate with the distributor and affects the material feeding efficiency of the shaft. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a shaft parts feeding device to solve the technical problem that shaft parts are difficult to fall accurately into the material distribution groove on the distributor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shaft-type parts feeding device, comprising two support frames and a rotating shaft, a distributor installed on the outer wall of the rotating shaft, and four distribution grooves on the outer wall of the distributor, a fixing plate installed on the top of each of the two support frames, and a material box installed between the two fixing plates, a material guiding assembly provided inside the material box, and the material guiding assembly comprising a movable shaft connected to the inside of the material box by a bearing and a material guiding seat installed on one side inside the material box, a material guiding column installed on the outer wall of the movable shaft, and four material guiding grooves opened on the outer wall of the material guiding column, a sprocket installed at one end of the movable shaft extending to the outside of the material box and one end of the rotating shaft, and a chain sleeved between the two sprockets, and a first protective pad installed on the inner wall of the distribution groove and the inner wall of the material guiding groove.

[0007] By adopting the above technical solution, when the rotating shaft rotates, it can drive the sprocket connected to it to rotate, and then drive another sprocket to rotate through the chain, which in turn drives the movable shaft to rotate.

[0008] Furthermore, a first horizontal plate and a second horizontal plate are respectively installed on one side of the two support frames, a material distribution cylinder is installed between the two first horizontal plates, and a rotating shaft is connected inside the material distribution cylinder through a bearing.

[0009] By adopting the above technical solution, the rotation of the shaft can drive the distributor to rotate, which in turn drives the distribution trough to rotate.

[0010] Furthermore, a driven gear is installed on the outer wall of the rotating shaft, a motor housing is installed on the outer surface of one of the first horizontal plates, and a motor is installed inside the motor housing.

[0011] By adopting the above technical solution, when the shaft needs to rotate, the motor can be started, and the motor can drive the drive gear to rotate.

[0012] Furthermore, the output end of the motor extends to the outside of the motor housing and is connected to a drive gear, which meshes with the driven gear.

[0013] By adopting the above technical solution, when the driving gear rotates, it will drive the driven gear to rotate, and the rotation of the driven gear will drive the shaft to rotate.

[0014] Furthermore, the bottom of the material bin extends into the interior of the material distribution cylinder, and a guide port is provided at the bottom of the material bin.

[0015] By adopting the above technical solution, the shaft inside the material box can fall into the material distribution cylinder through the guide port.

[0016] Furthermore, the bottom of the dispensing cylinder is provided with a discharge port.

[0017] By adopting the above technical solution, the discharge port is designed to facilitate the downward discharge of the shaft from the distribution cylinder.

[0018] Furthermore, a support base is installed between the two second horizontal plates, and clearance openings are provided on the upper sides of both sides of the support base. An electric push rod is installed inside the support base, and a push block is installed at the output end of the electric push rod through a piston rod.

[0019] By adopting the above technical solution, after the shaft falls into the support seat, the electric push rod can be activated. The operation of the electric push rod can extend the piston rod, thereby driving the push block to move, so that the push block can push the shaft to move.

[0020] Furthermore, a second protective pad is installed inside the lower part of the support base, and the second protective pad is located directly below the discharge port.

[0021] By adopting the above technical solution, when the shaft falls into the support base, the shaft will come into contact with the second protective pad. The second protective pad will deform after being impacted, so as to buffer the impact force generated when the shaft falls.

[0022] Furthermore, a top plate is installed on the top of the material box, and a cover plate is installed on one side of the top plate via a hinge. A material inlet is opened on one side of the top of the material box.

[0023] By adopting the above technical solution, when it is necessary to add shaft parts into the material box, the staff can first open the cover plate so that the cover plate no longer blocks the feed inlet, and then add the shaft parts into the material box through the feed inlet.

[0024] Furthermore, the top of the guide seat is sloped, and an arc-shaped groove is formed on the lower side of one side of the guide seat.

[0025] By adopting the above technical solution, the shaft will roll along the inclined direction after falling onto the guide seat, so that the shaft can roll downward.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model is equipped with a material guiding component. When the rotating shaft rotates, it can drive the sprocket connected to it to rotate, and then drive another sprocket to rotate through the chain, which in turn drives the movable shaft to rotate. The movable shaft drives the material guiding column to rotate, which in turn drives the material guiding groove to rotate, thereby driving the shaft in the material guiding groove to move. This allows the shaft to fall into the material distributing cylinder in an orderly manner. When the shaft falls into the material distributing cylinder, the bottom material guiding groove will be aligned with the top material distributing groove of the distributor, so that the shaft can fall accurately into the material distributing groove. This ensures that the shaft can rotate when the distributor rotates, thereby ensuring that the material distributing groove can be loaded smoothly and improving the material unloading efficiency of the shaft.

[0028] 2. This utility model has a first protective pad. When the first protective pad is hit by the shaft, it will deform, thereby buffering the impact force generated by the shaft impact. This prevents the shaft from falling down into the material distribution groove on the distributor and colliding with the inner wall of the material distribution groove, thus providing a certain degree of protection for the distributor.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A feeding device for shaft-type parts, such as Figures 1-6 As shown, it includes two support frames 1 and a rotating shaft 11. A distributor 12 is installed on the outer wall of the rotating shaft 11, and the outer wall of the distributor 12 is provided with four distribution slots 13. A fixing plate 2 is installed on the top of each of the two support frames 1, and a material box 3 is installed between the two fixing plates 2. A material guide assembly 8 is provided inside the material box 3. A top plate 6 is installed on the top of the material box 3. A cover plate 25 is installed on one side of the top plate 6 via a hinge. A feed port 7 is opened on one side of the top of the material box 3. When it is necessary to add a shaft into the material box 3, the operator can first open the cover plate 25 so that the cover plate 25 no longer blocks the feed port 7, and then the shaft can be added into the material box 3 through the feed port 7. The top plate 6 is made of acrylic material.

[0040] Specifically, the material guiding assembly 8 includes a movable shaft 802 connected to the inside of the material box 3 via bearings and a material guiding seat 801 installed on one side inside the material box 3. A material guiding column 803 is installed on the outer wall of the movable shaft 802, and four material guiding grooves 806 are formed on the outer wall of the material guiding column 803. A sprocket 804 is installed at one end of the movable shaft 802 extending outside the material box 3 and at one end of the rotating shaft 11, and a chain 805 is sleeved between two sprockets 804. The inner walls of the material distribution groove 13 and the inner walls of the material guiding grooves 806 are both equipped with… The first protective pad 10 is made of rubber material. When the rotating shaft 11 rotates, it can drive the sprocket 804 connected to it to rotate. Then, the chain 805 drives another sprocket 804 to rotate, and drives the movable shaft 802 to rotate. The top of the guide seat 801 is set with an incline so that after the shaft falls onto the guide seat 801, it will roll along the incline direction, so that the shaft can roll downward. An arc groove is opened on one side of the guide seat 801 so that the guide column 803 can rotate smoothly.

[0041] See Figure 1 , Figure 2 , Figure 5 and Figure 6 Two support frames 1 are respectively equipped with a first horizontal plate 4 and a second horizontal plate 19 on one side. A material distribution cylinder 5 is installed between the two first horizontal plates 4. The inside of the material distribution cylinder 5 is connected to a rotating shaft 11 through a bearing. The rotation of the rotating shaft 11 can drive the distributor 12 to rotate, and then drive the material distribution trough 13 to rotate. A driven gear 17 is installed on the outer wall of the rotating shaft 11. A motor box 14 is installed on the outer surface of one of the first horizontal plates 4. A motor 15 is installed inside the motor box 14. When the rotating shaft 11 needs to be rotated, the motor 15 can be started. The operation of the motor 15 can drive the drive gear 16 to rotate. The output end of the motor 15 extends to the outside of the motor box 14 and is connected to the drive gear 16. The diameter of the drive gear 16 is smaller than the diameter of the driven gear 17, which can reduce the speed of the driven gear 17. The drive gear 16 meshes with the driven gear 17. When the drive gear 16 rotates, it will drive the driven gear 17 to rotate. The rotation of the driven gear 17 will drive the rotating shaft 11 to rotate.

[0042] Specifically, the bottom of the material box 3 extends into the interior of the distribution cylinder 5. A guide port 9 is provided at the bottom of the material box 3, through which the shaft inside the material box 3 can fall into the interior of the distribution cylinder 5. The bottom of the distribution cylinder 5 is provided with a discharge port 18, which facilitates the shaft falling downward from the distribution cylinder 5. A support base 20 is installed between the two second horizontal plates 19. A clearance opening 23 is provided on the upper sides of both sides of the support base 20. An electric push rod 21 is installed inside the support base 20, and a push block 22 is installed at the output end of the electric push rod 21 through a piston rod. After the shaft falls into the interior of the support base 20, the electric push rod 21 can be activated. The operation of the electric push rod 21 can extend the piston rod, thereby driving the push block 22 to move, so that the push block 22 can push the shaft to move.

[0043] Example 2:

[0044] Based on the above embodiment 1, in order to prevent the shaft falling from the discharge port 18 from colliding directly with the lower interior of the support base 20, the following structure will be set.

[0045] See Figures 2-4 A second protective pad 24 is installed inside the lower part of the support base 20. The second protective pad 24 is made of rubber material and is located directly below the discharge port 18. When the shaft falls into the support base 20, the shaft will come into contact with the second protective pad 24. The second protective pad 24 will deform after being impacted, so as to buffer the impact force generated when the shaft falls and prevent the shaft from directly hitting the support base 20.

[0046] The working principle of this utility model is as follows: First, when in use, the power is turned on. Then, the operator opens the cover plate 25 and adds the shaft into the material box 3 through the feed port 7. The shaft will roll on the guide seat 801 and enter into a guide groove 806. Next, the motor 15 is started. The motor 15 drives the drive gear 16 to rotate, which in turn drives the driven gear 17 to rotate, which in turn drives the rotating shaft 11 to rotate, and drives the distributor 12 to rotate. At the same time, it drives the sprocket 804 at the end of the rotating shaft 11 to rotate, and then drives another sprocket 804 to rotate through the chain 805. Then, it drives the movable shaft 802 to rotate, and the movable shaft 802 drives the guide groove 806 to rotate, so that the shaft inside the guide groove 806 rotates to the top of the guide port 9 and falls into the distribution groove 13 on the distributor 12. When the first protective pad 10 is hit by the shaft, it will deform, thereby buffering the impact force generated by the shaft impact. The shaft in the material box 3 will slide into another corresponding guide groove 806. As the distributor 12 and guide column 803 continue to rotate, the shaft can fall into the distribution groove 13 on the distributor 12 in an orderly manner. When the shaft on the distribution groove 13 rotates to the top of the discharge port 18, the shaft will fall down into the discharge port 18 and then into the support base 20. The shaft will contact the second protective pad 24. The second protective pad 24 will deform after being impacted to buffer the impact force generated when the shaft falls. Then, the electric push rod 21 is activated to extend the piston rod, thereby driving the push block 22 to move. The push block 22 pushes the shaft to move so that the shaft is no longer located directly below the distribution cylinder 5. When the shaft is pushed to the vicinity of the relief port 23, the electric push rod 21 works to retract the piston rod, thereby driving the push block 22 to reset and move. The external robotic arm then removes the shaft, thus completing the feeding operation.
