Description

Technical Field

[0001] This invention relates to a conveying machine, and more particularly to a vertical conveying machine for shaft-type parts. Background Technology

[0002] For shaft-like parts whose axial length far exceeds their diameter, horizontal placement and support are generally used for handling. However, for shaft-like parts whose axial length is less than their diameter, or for those requiring vertical assembly, vertical handling is more convenient. Existing shaft-like parts generally have bosses, and the support locations and methods for these parts need to be considered during vertical handling. If the upper and lower ends of the shaft are selected as support locations, clamping devices are required to clamp the upper and lower ends separately. These clamping devices leave marks on the shaft surface, and existing clamping devices are difficult to match shafts of different diameters. Furthermore, clamping the lower end of the shaft affects the vertical assembly process between the shaft-like part and other components, while clamping only the upper end can lead to wobbling during handling due to unstable clamping. Summary of the Invention

[0003] This invention provides a vertical transporter for shaft parts to overcome the shortcomings of existing shaft parts transport devices, such as unstable clamping and difficulty in clamping shafts of different diameters.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: This invention discloses a vertical conveying machine for shaft parts, including a crossbeam with columns at both ends for ground support. A sleeve is located below the crossbeam, with a top cover at the upper end of the sleeve and a moving rod connected to the lower end of the sleeve. A traveling motor is installed inside the top cover, and a roller is connected to the output end of the traveling motor. The roller is located inside the crossbeam, and the traveling motor enables the roller to reciprocate within the crossbeam. A drive cylinder is provided between the top cover and the sleeve, and the lower end of the moving rod is connected to a clamp for holding parts. The drive cylinder enables the vertical movement of the clamp.

[0005] Furthermore, the clamp includes an annular tube with a plurality of commutator motors evenly distributed circumferentially. The rotor ends of the commutator motors are coaxially connected to a drive gear, which meshes with driven teeth on the circumferential edge of a driven ring on one side. The driven teeth are evenly arranged circumferentially on the driven ring. A follower ring is provided on an adjacent side of the driven ring, and the driven ring and the adjacent follower ring share a common rotation center line. A drive rod is radially arranged on the driven ring, and a telescopic cylinder is fixedly provided radially on the circumferential edge of the follower ring. The free end of the drive rod is hinged to the adjacent end of a support rod. A support plate is provided on the upper side of the support rod, and the support plate is fan-shaped and fixedly connected to the support rod. The hinge point between the drive rod and the support rod is located outside the support plate. An angled frame is provided on the lower side of the support rod, and the support plate, support rod, and angled frame share a plane of symmetry. Several pairs of telescopic pads are symmetrically provided on the bottom wall of the support plate on both sides of the plane of symmetry. A support block is provided on the lower side of the telescopic pads. A hinged column is provided on the side wall of the support block adjacent to the active rod. The support block is hinged to the free end of the piston rod of the adjacent guide cylinder through the hinged column and the hinged sleeve on its outer side. The cylinder end of the guide cylinder on one side of the plane of symmetry of the support plate is fixedly connected to the circumferential outer wall of the guide sleeve A. The cylinder end of the guide cylinder on the other side of the plane of symmetry of the support plate is connected to the support seat. The support seat is connected to a pair of support arms. The pair of support arms are fixedly connected to the circumferential outer walls of a pair of guide sleeves B respectively.

[0006] Furthermore, a side plate is connected to the lower side of the top cover, and a hollow sleeve with a square or annular cross-section is connected to the lower side of the side plate. The cross-section of the crossbeam is U-shaped and the openings of each other are arranged opposite to each other. Rollers are rolled in the U-shaped opening of the crossbeam.

[0007] Furthermore, a piston rod is provided below the drive cylinder, and the lower end of the piston rod is connected to the top end of the moving rod.

[0008] Furthermore, the support plate is a metal plate with elastic deformation capability.

[0009] Furthermore, the telescopic gasket is made of elastic material, and a connecting post is inserted inside the telescopic gasket. The support plate and the support block are connected by threads through the connecting post.

[0010] Furthermore, the middle of the angled frame is at a right angle, and its two ends are fixedly connected to the outer wall of the support rod, respectively. The free end of the piston rod of the telescopic cylinder is hinged to the right-angled part of the angled frame. The beneficial effects achieved by the present invention are: this structure can adapt to cylindrical or conical bosses on shaft parts, using the bosses as support parts, and clamping the shaft parts using the weight of the parts themselves without applying additional clamping force, thus ensuring the stability of clamping and enabling vertical assembly of shaft parts.

[0012] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0013] Example 1, as Figures 1-8 As shown, a vertical conveyor for shaft parts includes a pair of horizontal and parallel beams 1. Each beam 1 is supported on the ground at both ends by columns 2. The cross-section of the beams 1 is U-shaped, with the openings facing away from each other. Rollers 3 are rolled within the U-shaped openings of the beams 1. The rollers 3 are connected to axles 4, and the rollers 3 and axles 4 share a common centerline. The outer ends of the axles 4 are connected to a top cover 5. A motor for driving adjacent axles 4 is located inside the top cover 5. A pair of parallel side plates 6 are connected to the lower side of the top cover 5. A hollow sleeve 7 with a square or annular cross-section is connected to the lower side of the side plate 6. A moving rod 8 is slidably fitted inside the sleeve 7. A drive cylinder 9 is provided between the top cover 5, the side plate 6 and the sleeve 7. The cylinder body of the drive cylinder 9 is fixedly connected to the sleeve 7. A piston rod 10 is provided below the drive cylinder 9. The lower end of the piston rod 10 is connected to the top end of the moving rod 8 and is adapted to drive the reciprocating movement of the moving rod 8. The lower end of the moving rod 8 has a through hole and is fixedly connected to the annular tube 1201 on the clamp 12 used to clamp the part 11.

[0014] like Figure 1 and Figure 9 As shown, the clamp 12 includes a horizontally arranged, hollow annular tube 1201. A plurality of commutator motors 1202 are evenly distributed circumferentially on the annular tube 1201. Each commutator motor 1202 has a drive gear 1203 coaxially connected to its rotor end. Each drive gear 1203 meshes with a driven tooth 1204 on the circumferential edge of an adjacent driven ring 1205. The driven teeth 1204 are evenly arranged circumferentially on the driven ring 1205 within a set angle range. The driven ring 1205 rotatably fits into a radial annular groove in the annular tube 1201. Figure 13 As shown, each driven ring 1205 has a follower ring 1206 adjacent to one side. The follower ring 1206 rotatably engages in another annular groove along the radial direction of the annular tube, and the driven ring 1205 and the adjacent follower ring 1206 share the same center line of rotation. Each driven ring 1205 has a drive rod 1207 along the radial direction of the driven ring 1205 at the circumferential portion where the driven tooth 1204 is not provided. Each follower ring 1206 has a telescopic cylinder 1208 along the radial direction of the follower ring at its circumferential edge, and its cylinder body is fixedly connected to the follower ring 1206. Figures 9-10As shown, the free ends of each active rod 1207 are hinged to the adjacent ends of the corresponding support rods 1209. Each support rod 1209 has a support plate 1210 on its upper side. The support plate 1210 is fan-shaped and fixedly connected to the support rod 1209. The hinge points between the active rods 1207 and the support rods 1209 are located on the outer side of the support plate 1210. An angled frame 1211 is provided on the lower side of each support rod 1209. The middle of the angled frame 1211 is at a right angle, and its two ends are fixedly connected to the outer wall of the support rod 1209. The support plate 1210, support rods 1209, and angled frame 1211 share a plane of symmetry. The free end of the piston rod of the telescopic cylinder 1208 is hinged to the right-angle portion of the angled frame 1211, as shown... Figure 9 and Figure 11 As shown, the support plate 1210 has several pairs of telescopic pads 1212 symmetrically arranged on the bottom walls on both sides of the plane of symmetry. Each telescopic pad 1212 has a support block 1213 on its lower side. Figure 8 As shown, each support block 1213 has a hinge post 1214 on its side wall adjacent to the drive rod 1207. Each support block 1213 is hinged to the free end of the piston rod of the adjacent guide cylinder 1216 via the hinge post 1214 and its circumferentially outer hinge sleeve 1215. Wherein, as... Figures 11-12 As shown, the cylinder end of the guide cylinder 1216 located on one side of the symmetry plane of the support plate 1210 is fixedly connected to the circumferential outer wall of the guide sleeve A1217. The guide sleeve A1217 is rotatably fitted coaxially within the annular groove of the support rod 1209. The cylinder end of the guide cylinder 1216 located on the other side of the symmetry plane of the support plate 1210 is connected to the support seat 1218. The support seat 1218 is connected to a pair of support arms 1219. The pair of support arms 1219 are fixedly connected to the circumferential outer walls of a pair of guide sleeves B1220. The pair of guide sleeves B1220 are rotatably fitted coaxially within a pair of annular grooves on the support rod 1209, located on both sides of the annular groove where the guide sleeve A1217 is located. The three annular grooves on the support rod 1209, the guide sleeve A1217, and the guide sleeve B1220 are on the same axis of symmetry as the support rod 1209. The pair of guide cylinders 1216, which are symmetrically arranged on both sides of the symmetry plane of the support plate 1210, are arranged radially along the support rod 1209 and have the same symmetry plane as the support plate 1210.

[0015] The support rod 1209, support plate 1210, and telescopic pads 1212, support blocks 1213, hinge columns 1214, hinge sleeves 1215, and guide cylinders 1216 located on both sides of the support rod 1209 have a common plane of symmetry along the axial direction of the support rod 1209. The support plate 1210 is a metal plate with a certain elastic deformation capacity. Under the drive of the telescopic piston rod of the guide cylinder 1216, the support plate 1210 can bend and deform symmetrically on both sides around the aforementioned common axial plane of symmetry. Figure 8As shown, in order to ensure the support performance of the support plate 1210 when it is bent and deformed, the telescopic pad 1212 is made of elastic material such as rubber with a certain hardness. A connecting post 1221 is inserted inside the telescopic pad 1212. The top of the connecting post 1221 is fixedly connected to the bottom of the support plate 1210 by a thread, and the bottom of the connecting post 1221 is fixedly connected to the top of the support block 1213 by a thread. The connecting posts 1221 located on both sides of the support rod 1209 and their connection parts with the support plate 1210 and the support block 1213 are symmetrically arranged with respect to the common axial symmetry plane mentioned above. By connecting the connecting column 1221 to the support plate 1210, the impact of the displacement caused by the bending deformation of the support plate 1210 on the support block 1213 and the guide cylinder 1216 can be reduced. At the same time, the use of the elastically deformable telescopic pad 1212 allows the telescopic pad 1212 to deform synchronously when the support plate 1210 bends, achieving a tight fit between the telescopic pad 1212 and the adjacent surfaces of the support plate 1210. This increases the support area of ​​the support block 1213 on the support plate 1210 and improves the support stability of the support plate 1210 on the part 11.

[0016] Working principle: The rollers 3 are driven to roll by the built-in motor of the top cover 5, so that the sleeve 7 located under the pair of crossbeams 1 moves back and forth synchronously along the crossbeams 1. At the same time, the drive cylinder 9 on the sleeve 7 drives the moving rod 8 to descend vertically to the set height. When the clamp 12 moves to below the part 11, the drive motor and the moving rod 8 stop working, the reversing motor 1202 works and uses the drive gear 1203 and the driven gear 1204 on the driven ring 1205 to drive the driven ring 1205 to rotate around the annular tube 1201, thereby adjusting the orientation of the drive rod 1207. At the same time, the telescopic cylinder 1208 works and drives the angle frame 1211 to move, thereby adjusting the orientation of the support rod 1209 and the support plate 1210 on it, so that the angle between the support rod 1209 and the horizontal plane is adjusted to the set value, and the distance between the radial free end of the support plate 1210 and the part 11 is also adjusted to the set value. The extension of the piston rod of the guide cylinder 1216 on the lower side of the adjustable support plate 1210 is adjusted so that the bending deformation of the support plate 1210 is adjusted through the support block 1213. When the boss of part 11 has such Figure 3 When the outer conical surface is as shown, the support plate 1210 bends and deforms upward to reach a set deformation amount, so that the upper side of the support plate 1210 matches and fits the outer conical surface, improving the fit and support stability of the upper side of the support plate 1210 to the support surface of the part 11. When the boss of the part 11 has such Figure 5 When the inner conical surface is as shown, the support plate 1210 bends downward and deforms to reach a set deformation amount, so that the upper side of the support plate 1210 matches and fits against the inner conical surface. When the boss of part 11 has such Figure 6When the annular plane is as shown, the support plate 1210 does not bend and is in a horizontal state, as shown in the figure. Figure 7 As shown, after the relative position of the support plate 1210 and the part 11 and the orientation of the support plate 1210 are adjusted, the drive cylinder 9 drives the moving rod 8 to rise vertically, clamps the part 11 through the support plate 1210, and lifts the part 11 to a set height. Then, the travel motor drives the roller 3 to rotate synchronously, so that the clamp 12 moves the part 11 to a set position. The drive cylinder 9 drives the moving rod 8 to fall vertically again, lowers the part 11 clamped by the support plate 1210 to a set height and places it on the support of the part 11. Then, the reversing motor 1202, the telescopic cylinder 1208 and the guide cylinder 1216 reset, so that the support plate 1210 is disengaged from the part 11. The drive cylinder 9 and the travel motor work, so that the clamp 12 enters the clamping process of the next part 11.
