Description

TECHNICAL FIELD

[0001] The application relates to the technical field of shaft machining, in particular to a shaft part feeding device. BACKGROUND

[0002] Shaft parts are one of the typical parts frequently encountered in hardware fittings and mechanical products, and are mainly used to support gears, pulleys, cams and connecting rods in machines to transmit torque and bear load, and are connected with the frame of the machine through bearings. Shaft parts usually need to be processed to have spline, keyway, transverse hole, groove and other structures on the surface.

[0003] The surface processing of shaft parts usually relies on automatic machine tools: a mechanical hand accurately picks up a shaft part from a feeding device and sends it to a machine tool for fine processing; after processing is completed, the mechanical hand takes the finished product from the machine tool and sends it back to the feeding device or other designated unloading area. In the related art, a balanced shaft feeding rack is disclosed in Chinese Patent No. CN106743369A, which comprises a shell, support legs are installed around the bottom of the shell, a feeding hopper is arranged on one side of the upper surface of the shell, a sliding plate is arranged on the other side of the shell, a top plate is arranged on one side of the sliding plate, a track is connected below the top plate, limit pulleys are arranged on both sides of the track, a fixed support is arranged at the bottom of the shell, a cylinder is arranged inside the fixed support, a telescopic rod is connected to the upper end of the cylinder, a lifting support is fixedly connected to the top of the telescopic rod, and the lifting support is fixedly connected with the track.

[0004] For the above-mentioned related technology, the inventor believes that when the width of the feeding hopper exceeds the length of the balanced shaft, the placement of the balanced shaft in the width direction in the feeding hopper is prone to have a large positional deviation, so that after the feeding device completes the feeding action, the grabbing point of the mechanical hand is prone to deviate from the center of the balanced shaft when trying to grab the balanced shaft, thereby causing the balanced shaft to slide off, and sometimes the mechanical hand cannot successfully grab the balanced shaft, which still has room for improvement. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the problem that when the width of the feeding hopper exceeds the length of the balanced shaft, the grabbing point of the mechanical hand is prone to deviate from the center of the balanced shaft when trying to grab the balanced shaft after the feeding device completes the feeding action, thereby causing the balanced shaft to slide off, the application provides a shaft part feeding device.

[0006] The shaft part feeding device provided by the application adopts the following technical scheme:

[0007] The utility model provides a kind of shaft parts feeding device, including mounting bracket, feeding plate, adjusting assembly and the positioning plate for abutting to the end of shaft parts, the feeding plate is fixedly connected on the mounting bracket, the feeding plate is inclined downward along the length direction of itself, the positioning plate is located on the feeding plate, the positioning plate is perpendicular to the feeding plate, the length direction of the positioning plate and the length direction of the feeding plate are identical, the adjusting assembly is located on the feeding plate, to adjust the position of the positioning plate along the width direction of the feeding plate.

[0008] By adopting the above technical scheme, the adjusting assembly adjusts the position of the positioning plate along the width direction of the feeding plate, so that when different lengths of shaft parts need to be conveyed, the position of the positioning plate is adjusted to keep the shaft parts in a relatively appropriate position in the width direction of the feeding plate, ensuring that the gripping point is close to the center of the shaft part when the mechanical hand grips, reducing the risk of the shaft part falling off and improving the stability and accuracy of feeding.

[0009] Optionally, the edge of the feeding plate is fixedly connected with a connecting plate, the connecting plate and the positioning plate are arranged in parallel, at least two through holes are provided on the connecting plate, the adjusting assembly includes a screw rod and a first nut, the number of the screw rods is the same as the number of the through holes, the screw rod is fixedly connected to one side of the positioning plate close to the connecting plate, the screw rod is correspondingly threaded into the through hole, the number of the first nut is the same as the number of the screw rod, and the first nut is threadedly connected to the screw rod one by one, and the first nut abuts against one side of the connecting plate close to the positioning plate.

[0010] By the above technical scheme, when the first nut is rotated to adjust the distance between the first nut and the positioning plate, the positioning plate moves along the width direction of the feeding plate due to the abutment of the first nut against one side of the connecting plate close to the positioning plate, thereby adapting to the feeding requirements of shaft parts of different lengths and improving the versatility of the feeding device.

[0011] Optionally, a second nut is threadedly connected to the screw rod, and the second nut abuts against one side of the connecting plate away from the first nut.

[0012] By adopting the above technical scheme, when the first nut adjusts the position of the positioning plate, the second nut is tightened, and the first nut and the second nut cooperate with each other to clamp the positioning plate from both sides of the connecting plate, preventing the position of the positioning plate from shifting due to vibration and other factors during the feeding of shaft parts, thereby further ensuring the stability of the positioning plate remaining in a certain position.

[0013] Optionally, two gaskets are arranged on each screw, and the two gaskets are respectively abutted to two sides of the connecting plate, one gasket is abutted to the first nut away from one side of the connecting plate, and the other gasket is abutted to the second nut away from one side of the connecting plate.

[0014] By adopting the above technical scheme, compared with the first nut and the second nut directly abutting to the connecting plate, the gaskets increase the contact area between the two and the connecting plate, so that the pressure of the two on the connecting plate is more evenly distributed, the friction between the two and the connecting plate is enhanced, and the stability of the positioning plate installation is further improved.

[0015] Optionally, it also includes a baffle, a lifting plate with the same diameter as the shaft part, and at least two receiving rods for placing the shaft part for the robot to grab, the mounting frame is fixedly connected with a gas cylinder, the lifting plate is fixedly connected to the piston rod of the gas cylinder, the lifting plate is abutted to the lower end of the feeding plate, the height of the upper side wall of the lifting plate gradually decreases from the side close to the feeding plate to the side away from the feeding plate, the baffle is fixedly connected to the mounting frame, the baffle is abutted to the side of the lifting plate away from the feeding plate, the height of the upper side wall of the baffle is higher than the height of the side of the feeding plate close to the lifting plate, the receiving rod is fixedly connected to the side of the baffle away from the lifting plate, and the receiving rod is provided with a positioning groove for positioning the shaft part to be grabbed.

[0016] By adopting the above technical scheme, since the lifting plate is abutted to the lower end of the feeding plate and the width of the lifting plate is the same as the diameter of the shaft part, the shaft part closest to the baffle rolls along the feeding plate to the upper side of the lifting plate, when the gas cylinder drives the lifting plate to lift, since the height of the upper side wall of the lifting plate gradually decreases from the side close to the feeding plate to the side away from the feeding plate, the shaft part gradually rises along the lifting plate, and when the height of the upper side wall of the lifting plate is higher than the height of the upper side wall of the baffle, the shaft part rolls over the baffle to the positioning groove on the receiving rod for the robot to grab, thereby improving the automation performance of the feeding device.

[0017] Optionally, the lifting plate and the baffle are gradually inclined to the side close to the feeding plate from bottom to top.

[0018] By adopting the technical scheme, when the multiple shaft parts are placed on the upper side of the lifting plate, the baffle is inclined to the side close to the feeding plate, the shaft part on the upper side is limited by the baffle and the shaft part on the lower side is above the shaft part on the upper side, the shaft lines of the shaft parts on the upper side and the lower side are not in the same vertical direction, the shaft part on the upper side rolls away from the side of the baffle far from the shaft part on the lower side during the lifting of the lifting plate, and the stability of the lifting plate lifting one shaft part at a time is improved.

[0019] Optionally, the height of the receiving rod gradually decreases from the side close to the baffle to the side far from the baffle.

[0020] By adopting the technical scheme, the height of the receiving rod gradually decreases from the side close to the baffle to the side far from the baffle, so that when the shaft part rolls on the receiving rod to the positioning groove under the guidance of the receiving rod, the flow of the shaft part rolling into the positioning groove is improved.

[0021] Optionally, a limiting block is fixedly connected to the receiving rod and arranged on the side of the positioning groove far from the baffle.

[0022] By adopting the technical scheme, when the shaft part rolls on the receiving rod, the limiting block limits the rolling distance of the shaft part, avoids the shaft part from rolling out of the positioning groove due to too fast rolling speed, and improves the stability of the shaft part rolling into and staying in the positioning groove.

[0023] Optionally, a plurality of convex ribs for abutting against the lower side of the shaft part are fixedly connected to the feeding plate, the plurality of convex ribs are distributed along the width direction of the feeding plate, and each convex rib is arranged along the length direction of the feeding plate.

[0024] By adopting the technical scheme, compared with the shaft part directly abutting against the feeding plate, the convex rib reduces the contact area between the shaft part and the feeding plate, thereby reducing the friction between the shaft part and the feeding plate, reducing the wear of the feeding plate during the working process of the feeding device, and improving the service life of the feeding plate.

[0025] Optionally, a through hole is arranged on the connecting plate, the through hole penetrates through the side of the connecting plate far from the feeding plate, and one end of the through hole close to the feeding plate is in communication with the through hole.

[0026] By adopting the technical scheme, the through hole is cut on the connecting plate by the cutting machine, and then the through hole is cut to obtain the through hole, thereby improving the processing convenience of the through hole.

[0029] 2. By rotating the first nut, the distance between the first nut and the positioning plate is adjusted, so that the position of the positioning plate adapts to the feeding requirements of shaft parts of different lengths, improving the versatility of the feeding device;

[0030] 3. The first nut and the second nut respectively clamp the positioning plate from both sides of the connecting plate, preventing the positioning plate from shifting during feeding, and improving the stability of the positioning plate remaining in a certain position.

DETAILED DESCRIPTION

[0036] The following will be combined with the Figures 1-4 The present application is further described in detail.

[0037] The embodiment of the present application discloses a shaft part feeding device.

[0038] Referring to Figure 1 , the shaft part feeding device comprises a mounting frame 1, a feeding assembly 2 and an adjusting assembly 3. The feeding assembly 2 is installed on the mounting frame 1 to transport the shaft parts. The adjusting assembly 3 is installed on the feeding assembly 2 to adjust the position of the shaft part in the feeding assembly 2 along the length direction of the shaft part.

[0039] Referring toFigure 1 and Figure 2 The feeding assembly 2 comprises a feeding plate 21, a lifting plate 22, a baffle 23 and a receiving rod 24. The feeding plate 21 is fixedly connected to the mounting frame 1, and is arranged in an inclined downward manner along the length direction of the feeding plate 21, so that when the shaft parts are placed on the feeding plate 21, the shaft parts roll along the length direction of the feeding plate 21 to the lower end. In order to reduce the damage of the rolling of the shaft parts on the feeding plate 21, a plurality of ribs 211 are fixedly connected to the feeding plate 21. The plurality of ribs 211 are distributed along the width direction of the feeding plate 21, and each rib 211 is arranged along the length direction of the feeding plate 21 to abut the lower side of the shaft parts, thereby reducing the contact area between the feeding plate 21 and the shaft parts.

[0040] Referring to Figure 2 A cylinder 11 is fixedly connected to the mounting frame 1, and the piston rod of the cylinder 11 faces upward. The lifting plate 22 is fixedly connected to the piston rod of the cylinder 11, so as to drive the lifting plate 22 to lift or drop by the cylinder 11. The lifting plate 22 abuts the lower side of the feeding plate 21, so as to lift the shaft parts rolling on the lifting plate 22 from the feeding plate 21. The baffle 23 is fixedly connected to the mounting frame 1, and abuts the side of the lifting plate 22 away from the feeding plate 21. The height of the baffle 23 is higher than the height of the side of the feeding plate 21 close to the lifting plate 22, so as to limit the displacement of the shaft parts rolling on the lifting plate 22 from the feeding plate 21. The shaft parts abut the baffle 23 after rolling on the lifting plate 22, and no longer continue to roll. In order to avoid the lifting plate 22 lifting a plurality of overlapped shaft parts, the thickness of the lifting plate 22 is the same as the diameter of the shaft parts, and the lifting plate 22 and the baffle 23 are inclined from bottom to top towards the side close to the feeding plate 21. The height of the upper side wall of the lifting plate 22 gradually decreases from the side close to the feeding plate 21 to the side away from the feeding plate 21. When the lifting plate 22 is lifted by the cylinder 11, the height of the upper side wall of the lifting plate 22 is higher than the height of the baffle 23, so that the shaft parts roll on the upper side wall of the lifting plate 22 to the upper side wall of the baffle 23.

[0041] Referring to Figure 2The number of the receiving rods 24 is at least two, and in the embodiment of the present application, the number of the receiving rods 24 is two. The receiving rods 24 are fixedly connected to the side of the baffle 23 away from the lifting plate 22, and the receiving rods 24 are provided with positioning grooves 241, so as to position the position of the shaft part rolling on the receiving rods 24, and facilitate the gripping of the mechanical hand. The height of the receiving rods 24 gradually decreases from the side close to the baffle 23 to the side away from the baffle 23, so as to avoid the shaft part from stopping rolling when not rolling into the positioning groove 241. The receiving rods 24 are fixedly connected with limiting blocks 242, and the limiting blocks 242 are located at the side of the positioning groove 241 away from the baffle 23, so as to limit the rolling of the shaft part, and avoid the momentum of the shaft part from being too large to roll out of the positioning groove 241 and fall off.

[0042] With reference to Figure 3 and Figure 4 In order to keep the gripping point of the mechanical hand as the midpoint of the shaft part during the feeding process of the shaft parts with different lengths, the adjusting assembly 3 includes a positioning plate 31, a screw rod 32, a first nut 33 and a second nut 34. The positioning plate 31 is installed on the feeding plate 21, and the positioning plate 31 is arranged perpendicular to the feeding plate 21, and the length direction of the positioning plate 31 is the same as the length direction of the feeding plate 21, so as to abut the end of the shaft part. The edge of the feeding plate 21 is fixedly connected with a connecting plate 212, and the connecting plate 212 is arranged parallel to the positioning plate 31, so as to install the adjusting assembly 3. The connecting plate 212 is provided with at least two through holes 2121, and in the embodiment of the present application, the number of the through holes 2121 is two, and the two through holes 2121 penetrate through the side of the connecting plate 212 away from the feeding plate 21. The connecting plate 212 is also provided with the same number of penetrating holes 2122 as the number of the through holes 2121, and the penetrating holes 2122 one-to-one correspond to the ends of the through holes 2121 close to the feeding plate 21.

[0043] With reference to Figure 3 and Figure 4The number of the screw rods 32 is same as the number of the through holes 2122, one end of the screw rod 32 is fixedly connected to the positioning plate 31 close to one side of the connecting plate 212, and the screw rod 32 is correspondingly arranged in the through hole 2122. The number of the first nut 33 is same as the number of the screw rod 32, the first nut 33 is correspondingly screwed on the screw rod 32, and the first nut 33 is located on the side of the connecting plate 212 close to the positioning plate 31. The number of the second nut 34 is also same as the number of the screw rod 32, the second nut 34 is correspondingly sleeved on the screw rod 32, and the second nut 34 is located on the side of the connecting plate 212 away from the first nut 33. Two gaskets 321 are sleeved on each screw rod 32, and the two gaskets 321 are respectively abutted on two sides of the connecting plate 212, one of the two gaskets 321 is abutted on the first nut 33 away from the connecting plate 212, and the other gasket 321 is abutted on the second nut 34 away from the connecting plate 212, so as to increase the abutting area between the first nut 33 and the connecting plate 212 and between the second nut 34 and the connecting plate 212. The screw rod 32 and the positioning plate 31 are fixedly connected to the connecting plate 212 through the cooperation of the first nut 33 and the second nut 34 on two sides of the connecting plate 212, and the distance between the positioning plate 31 and the connecting plate 212 is adjusted by rotating the first nut 33 and the second nut 34, so that when the end of the shaft part of different lengths is abutted on the positioning plate 31, the midpoint of the shaft part is always aligned with the grabbing point of the mechanical hand.

[0044] The implementation principle of the shaft part feeding device is as follows: the position of the positioning plate 31 is adjusted by rotating the first nut 33 and the second nut 34, so that when the end of the shaft part to be processed is abutted on the positioning plate 31, the midpoint of the shaft part is aligned with the grabbing point of the mechanical hand; the shaft part to be processed is placed on the feeding plate 21 and pushed to make the end of the shaft part abut on the positioning plate 31; the cylinder 11 is started to drive the lifting plate 22 to lift the shaft part rolled on the lifting plate 22, so that the shaft part rolls over the baffle 23 and into the positioning groove 241, so as to be grabbed by the mechanical hand.
