Description
Technical Field
[0001] The utility model relates to the technical field of gearbox gear processing, in particular to a positioning and conveying device for gearbox gear processing. Background Art
[0002] Gearbox gears are high-precision mechanical parts. Compared with ordinary gears, they have higher process requirements in the manufacturing process. Their precision and quality need to be guaranteed throughout the entire production process. Positioning and conveying are an indispensable part of the production and processing of gearbox gears. By placing the workpiece in a specific position, fixing and conveying it, the processing accuracy and consistency of the gears are ensured, and the impact of bumps on the gear accuracy and quality during transportation is avoided, thereby ensuring the quality and performance of the gears.
[0003] The existing positioning and conveying device fixes and conveys the gearbox gears through placement seats evenly distributed on the surface of the conveyor belt. The surface of the placement seat is provided with a vertical rod body. The gearbox gear is mounted on the surface of the rod body to prevent the gearbox gear from detaching from the placement seat surface. However, the diameter specification of the rod body cannot be adjusted, so the specifications of the gearbox gear that can be adapted are very limited. When the inner ring diameter of the gearbox gear is larger than the diameter of the rod body, although the gear will not detach from the placement seat surface due to the limitation of the rod body, the gear will move relative to the placement seat due to external force collision or change in conveying speed, and in the process, the inner ring of the gear will collide with the rod body, which poses a risk of affecting the specification accuracy of the inner ring of the gear.
[0004] For this purpose, a positioning and conveying device for gearbox gear processing is proposed. Utility Model Content

[0025] like Figures 1 to 4As shown, a positioning and conveying device for gear processing of a gearbox includes a box seat 1, a conveyor belt body 2 is provided on the surface of the box seat 1, a bottom plate 3 is fixedly installed on the surface of the conveyor belt body 2, a threaded hole 4 is opened on the top surface of the bottom plate 3, the number of threaded holes 4 is several and evenly distributed on the top surface of the bottom plate 3, a carrier seat 14 is threadedly installed on the inner wall surface of the threaded hole 4, the carrier seat 14 includes a rotating mounting seat 5, the rotating mounting seat 5 is threadedly installed on the inner wall surface of the threaded hole 4, a column 6 is fixedly installed in the middle of the top surface of the rotating mounting seat 5, a fixed wedge block 7 with a narrow upper and wide lower shape is fixedly installed on the top surface of the column 6, the number of fixed wedge blocks 7 is several and evenly distributed in a circular array, a supporting plate 8 is slidingly sleeved on the surface of the column 6, a translation component 9 is provided on the top surface of the supporting plate 8, a stretching wedge block 10 is fixedly installed on the surface of the translation component 9, the stretching wedge block 10 is slidingly arranged in contact with the fixed wedge block 7, and an elastic support component 13 is fixedly connected between the supporting plate 8 and the opposite surface of the rotating mounting seat 5.
[0026] Specifically, by rotating the carrier 14, it is possible to quickly disassemble and assemble it on the surface of the bottom plate 3, and then adjust the spacing between adjacent carriers 14 so that the spacing meets the size requirements of the gearbox gear fixed by the carrier 14, and the gear is sleeved on the outside of the stretching wedge block 10 and placed on the top surface of the support plate 8. Under the action of the weight of the gear, the support plate 8 is pushed downward, so that the stretching wedge block 10 that fits the fixed wedge block 7 moves downward relative to the fixed wedge block 7. Under the push of the inclined surface of the fixed wedge block 7, the stretching wedge block 10 is prompted to move radially outward along the support plate 8, thereby causing several stretching wedge blocks 10 to open synchronously. When the stretching wedge block 10 contacts the inner ring surface of the gear and After the extrusion is formed, the gear can no longer move downward, and the stretching wedge block 10 supports and fixes the inner ring of the gear, so that the gears with different inner ring sizes can be flexibly and effectively fixed, and the fixing method is simple and efficient, and can be automatically achieved by simply placing the gear. In the process of opening several stretching wedge blocks 10, the elastic support component 13 and the translation component 9 are compressed to accumulate elastic potential energy. When the gear is removed, the support plate 8 will move upward under the elastic force of the elastic support component 13, and the translation component 9 will also use the elastic force to push the stretching wedge block 10 to move in the opposite direction to the axis of the support plate 8, thereby realizing the overall state recovery of the object carrier 14, and the gear picking and fixing process is simple and efficient.
[0027] There are several bottom plates 3 that are evenly distributed on the surface of the conveyor belt body 2. The rotating mounting seat 5 includes a threaded column 501, which is threadedly installed on the inner wall surface of the threaded hole 4. The top surface of the threaded column 501 is fixed with a base 502 on the box seat 1, and a handle 503 is fixedly installed on the side of the base 502. The handle 503 is annular. The column 6 is fixedly installed in the middle of the top surface of the base 502. The elastic support assembly 13 is fixedly installed on the top surface of the base 502. There are several elastic support assemblies 13 that are evenly distributed in a circular array.
[0028] Specifically, during the process of installing or disassembling the object carrier 14, the gripping handle 503 can drive the base 502 and the threaded column 501 to rotate, and then the threaded column 501 can be threadedly installed in the threaded hole 4 or the threaded column 501 can be removed from the threaded hole 4, which facilitates the rapid disassembly and assembly of the object carrier 14. The elastic support components 13 evenly distributed in the annular array can provide stable support for the support plate 8, ensuring that the lifting and lowering of the support plate 8 remains stable and reliable.
[0029] The translation assembly 9 includes a radial slide groove 901, which is radially opened on the top surface of the support plate 8. A translation block 902 is slidably installed on the inner wall surface of the radial slide groove 901. A guide rod 903 is fixedly installed on the inner wall surface of the radial slide groove 901 along the radial direction of the support plate 8. A return spring 904 is fixedly installed on the side surface of the translation block 902 away from the axis of the support plate 8. The return spring 904 is fixedly connected to the inner wall surface of the radial slide groove 901 and is sleeved on the outside of the guide rod 903. The stretching wedge block 10 is fixedly installed on the top surface of the translation block 902.
[0030] Specifically, when the stretching wedge block 10 moves downward, the inclined surface of the fixed wedge block 7 pushes the stretching wedge block 10 to move radially outward along the support plate 8. At this time, the translation block 902 moves synchronously with the fixed wedge block 7 and squeezes the return spring 904 to compress it. In the process of compressing the return spring 904, the return spring 904 will apply a reaction force to slow down the movement speed of the translation block 902, thereby making the opening speed of the stretching wedge block 10 smooth and stable, avoiding the stretching wedge block 10 from opening quickly and causing impact on the inner ring of the gear. When the support plate 8 moves upward, the return spring 904 gradually recovers and pushes the translation block 902 and the stretching wedge block 10 to reset.
[0031] A rubber pad 11 is fixedly mounted on a surface of the stretching wedge block 10 away from the axis of the supporting plate 8 .
[0032] Specifically, the elasticity and high friction coefficient of the rubber pad 11 are utilized to buffer the rigid force exerted by the stretching wedge block 10 on the inner ring of the gear, thereby avoiding slight deformation of the inner ring of the gear, ensuring the accuracy of the gear, and increasing the friction force on the inner ring of the gear, making the fixation of the gearbox gear more stable and reliable.
[0033] A sliding connection assembly 12 is provided between the column 6 and the supporting plate 8. The sliding connection assembly 12 includes a T-shaped groove 121 and a T-shaped slider 122. The T-shaped groove 121 is opened on the side of the column 6, the T-shaped slider 122 is fixedly installed on the inner surface of the supporting plate 8, and the T-shaped slider 122 is slidably installed on the inner wall surface of the T-shaped groove 121.
[0034] Specifically, the T-shaped slider 122 slides up and down on the inner wall surface of the T-shaped slot 121, so that the sliding connection between the support plate 8 and the column 6 is tighter and more reliable, thereby ensuring that the support plate 8 still has strong stability after repeated lifting and lowering, and will not shake relative to the column 6.
[0035] The elastic support assembly 13 includes a sleeve column 131, which is fixedly mounted on the top surface of the rotating mounting seat 5. A limiting slider 132 is slidably mounted on the inner wall surface of the sleeve column 131. A telescopic column 133 is fixedly mounted on the top surface of the limiting slider 132. The telescopic column 133 is slidably inserted into the top surface of the sleeve column 131. The top surface of the telescopic column 133 is fixedly mounted on the bottom surface of the supporting plate 8. A damping spring 134 is provided on the outside of the sleeve column 131 and the telescopic column 133. The damping spring 134 is fixedly mounted between the opposite surfaces of the rotating mounting seat 5 and the supporting plate 8.
[0036] Specifically, when the support plate 8 moves downward due to the pressure exerted by the gear, the telescopic column 133 and the limit slider 132 move downward, and the damping spring 134 is squeezed. The damping spring 134 exerts a reverse force on the support plate 8 while being compressed, so as to prevent the support plate 8 from descending too quickly after the gear is placed, thereby reducing the speed at which the stretching wedge block 10 opens, and preventing the stretching wedge block 10 from opening too quickly and impacting the inner ring surface of the gear, causing deformation of the inner ring of the gear. When the gear is picked up, under the action of the damping spring 134, the telescopic column 133 and the limit slider 132 move upward, so that the support plate 8 is restored to its original height.
[0037] To sum up: the gear is sleeved on the outside of the stretching wedge block 10 and placed on the top surface of the support plate 8. Under the action of the gravity of the gear, the support plate 8 is pushed downward, so that the stretching wedge block 10 that is in contact with the fixed wedge block 7 moves downward relative to the fixed wedge block 7. Under the push of the inclined surface of the fixed wedge block 7, the stretching wedge block 10 is prompted to move radially outward along the support plate 8, so that several stretching wedge blocks 10 are opened synchronously. When the stretching wedge block 10 contacts the surface of the inner ring of the gear and forms an extrusion, the gear can no longer move downward. The stretching wedge block 10 supports and fixes the inner ring of the gear, and thus can flexibly and effectively fix gears with different inner ring sizes. In addition, the fixing method is simple and efficient, and can be automatically achieved by simply placing the gear.
