Description

Technical Field

[0001] This utility model relates to the technical field of lifting component structure of racket stringing machine, and in particular to a high-stability lifting component of racket stringing machine. Background Technology

[0002] After the racket is manufactured, workers need to use a racket stringing machine to thread and fix the elastic strings, arranged in a mesh pattern, inside the racket. A certain model of racket stringing machine mainly includes a lifting assembly and a stringing assembly. The structure of the lifting assembly is as follows: Figure 1 As shown, it includes a lifting cylinder 1 and a base 2 fixed on a pad. The base 2 is located to the left of the lifting cylinder 1. A vertically arranged guide rail 3 is fixed on the right end face of the base 2. A connecting column 4 is fixed to the top of the lead screw of the lifting cylinder 1. A platform 5 is fixed to the top of the connecting column 4. A lifting cylinder 6 sleeved on the outside of the connecting column 4 is fixed to the bottom surface of the platform 5. A slider 7 is fixed to the left outer wall of the lifting cylinder 6. The slider 7 is slidably installed on the guide rail 3. The platform 5 is used to connect with the stringing assembly of the racket stringing machine.

[0003] In use, the worker controls the lifting cylinder 1 to start. The lead screw of the lifting cylinder 1 drives the connecting column 4 to move upward, the connecting column 4 drives the platform 5 to move upward, the platform 5 drives the cable assembly and the lifting cylinder 6 to move upward synchronously, and the lifting cylinder 6 drives the slider 7 to move upward along the guide rail 3. When the worker observes that the cable assembly has been lifted to the worker's operating height, such as... Figure 2 As shown, the worker controls the lifting electric cylinder 1 to shut down.

[0004] However, while this lifting assembly is usable, it still suffers from the following technical defects:

[0005] I. When the worker threades the elastic string into the racket through the string assembly, the string assembly applies a reaction force to the platform 5. This reaction force causes the lifting cylinder 6 and the slider 7 to shake, which in turn causes the string assembly to shake synchronously. This reduces the stringing quality of the racket and has the technical defect of low stability.

[0006] II. The lifting assembly can only adjust the height of the platform 5, but cannot adjust the pitch angle of the platform 5, and therefore cannot adjust the pitch angle of the cable assembly. As a result, the cable assembly cannot be adapted to the operator's operating habits.

[0007] Therefore, there is an urgent need for a lifting assembly that can effectively prevent the cable assembly from shaking during operation and can adjust the pitch angle of the cable assembly. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a highly stable lifting component for racket stringing machines that effectively prevents shaking of the string assembly during operation and can adjust the pitch angle of the string assembly.

[0009] The purpose of this utility model is achieved through the following technical solution: a high-stability lifting component for a racket stringing machine, which includes a fixed cylinder fixed on the top surface of the base, and a vertically arranged left side guide rail and a rear side guide rail fixed on the left end face and the rear end face of the fixed cylinder, respectively. A left side slider and a rear side slider are slidably installed on the left side guide rail and the rear side guide rail, respectively, and the left side slider and the rear side slider are offset from each other in the height direction.

[0010] A lifting cylinder is fixedly mounted on the top surface of the base. A rod is fixedly connected to the top end of the lead screw of the lifting cylinder. The rod passes through the fixed cylinder upwards and a lifting plate is fixedly mounted on the extended end. A lifting cylinder sleeved outside the fixed cylinder is fixedly mounted on the bottom surface of the lifting plate. The left inner wall and the rear inner wall of the lifting cylinder are respectively fixed on the left slider and the rear slider.

[0011] A platform parallel to the lifting plate is provided directly above it, and a pitch adjustment mechanism that can adjust the pitch angle of the platform is provided between the platform and the lifting plate.

[0012] The left slider is located above the rear slider.

[0013] Both the fixed cylinder and the lifting cylinder have through slots in their front panels. The cylinder body of the lifting cylinder passes through the through slots of the lifting cylinder and the fixed cylinder in sequence, and is fixed to the top surface of the base.

[0014] The lifting cylinder has multiple weight-reducing rectangular slots on each of its four panels.

[0015] The pitch adjustment mechanism includes a housing fixed to the top surface of the lifting plate, a fixed shaft passing through the front and rear walls of the housing, a platform hinged to the fixed shaft, and a pitch cylinder installed inside the housing. The cylinder body of the pitch cylinder is hinged to the top surface of the lifting plate via a hinge seat, and the lead screw of the pitch cylinder is hinged to the bottom surface of the platform.

[0016] On the bottom surface of the platform, at its left and right ends, a long connecting seat and a short connecting seat are respectively fixed. The short connecting seat is hinged to the fixed shaft, and the long connecting seat is hinged to the lead screw of the pitching electric cylinder.

[0017] Both the lifting electric cylinder and the pitching electric cylinder are electrically connected to the controller via signal lines.

[0018] This utility model has the following advantages: it effectively prevents the cable assembly from shaking during operation and allows for adjustment of the cable assembly's pitch angle. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0037] like Figures 3-12 As shown, a high-stability lifting assembly for a racket stringing machine includes a fixed cylinder 9 fixed to the top surface of a base 8. A vertically arranged left side guide rail 10 and a rear side guide rail 11 are fixed to the left end face and the rear end face of the fixed cylinder 9, respectively. A left side slider 12 and a rear side slider 13 are slidably mounted on the left side guide rail 10 and the rear side guide rail 11, respectively. The left side slider 12 and the rear side slider 13 are offset in the height direction, and the left side slider 12 is located above the rear side slider 13.

[0038] A lifting cylinder 1 is fixedly mounted on the top surface of the base 8. A rod 14 is fixedly connected to the top end of the lead screw of the lifting cylinder 1. The rod 14 passes through the fixed cylinder 9 upwards, and a lifting plate 15 is fixedly mounted on the extended end. A lifting cylinder 6, which is sleeved on the outside of the fixed cylinder 9, is fixedly mounted on the bottom surface of the lifting plate 15. The left inner wall and the rear inner wall of the lifting cylinder 6 are respectively fixed on the left slider 12 and the rear slider 13. Multiple weight-reducing rectangular grooves 18 are opened on the four panels of the lifting cylinder 6 to reduce the weight of the lifting cylinder 6.

[0039] A platform 5 is provided directly above the lifting plate 15 and parallel to it. A pitch adjustment mechanism 16 is provided between the platform 5 and the lifting plate 15 to adjust the pitch angle of the platform 5. The front panels of the fixed cylinder 9 and the lifting cylinder 6 are both provided with through slots 17. The cylinder body of the lifting electric cylinder 1 passes through the through slots 17 of the lifting cylinder 6 and the fixed cylinder 9 in sequence, and is fixed to the top surface of the base 8.

[0040] The pitch adjustment mechanism 16 includes a housing 19 fixed to the top surface of the lifting plate 15. A fixed shaft 20 is fixed inside the housing 19 and passes between the front and rear walls of the housing 19. A platform 5 is hinged to the fixed shaft 20. A pitch cylinder 21 is also provided inside the housing 19. The cylinder body of the pitch cylinder 21 is hinged to the top surface of the lifting plate 15 via a hinge seat 22. The lead screw of the pitch cylinder 21 is hinged to the bottom surface of the platform 5. A long connecting seat 23 and a short connecting seat 24 are fixed to the bottom surface of the platform 5 at its left and right ends, respectively. The short connecting seat 24 is hinged to the fixed shaft 20, and the long connecting seat 23 is hinged to the lead screw of the pitch cylinder 21. When adjusting the angle of the cable assembly on platform 5, the worker only needs to control the motor in the pitch cylinder 21 to start in the forward or reverse direction. The lead screw of the pitch cylinder 21 drives the long connecting seat 23 to move up or down. The long connecting seat 23 drives the platform 5 to rotate clockwise or counterclockwise around the fixed axis 20. The platform 5 drives the cable assembly on it to rotate synchronously, thereby changing the pitch angle of the cable assembly, so that the cable assembly can adapt to the worker's operating habits.

[0041] Both the lifting cylinder 1 and the pitch cylinder 21 are electrically connected to the controller via signal lines. The worker can control the start or stop of the lifting cylinder 1 and the pitch cylinder 21 through the controller. When the motor in the lifting cylinder 1 starts in the forward or reverse direction, the lead screw of the lifting cylinder 1 pushes the rod 14 upward or pulls the rod 14 downward. When the motor in the pitch cylinder 21 starts in the forward or reverse direction, the lead screw of the pitch cylinder 21 pushes the long connecting seat 23 upward or pulls the long connecting seat 23 downward, thereby facilitating the worker's operation.

[0042] The working principle of this utility model is as follows:

[0043] Before use, the worker installs the string assembly onto the top surface of platform 5. After installation, this lifting assembly and the string assembly together form the racket stringing machine. During operation, the worker first controls the lifting cylinder 1 to start. The lifting cylinder 1 drives the rod 14 to move upward, the rod 14 drives the lifting plate 15 to move upward, and the lifting plate 15 drives the pitch adjustment mechanism 16, platform 5 and string assembly to move upward synchronously. At the same time, the lifting plate 15 also drives the lifting cylinder 6 to move upward. The lifting cylinder 6 drives the left slider 12 and the rear slider 13 to slide upward along the left guide rail 10 and the rear guide rail 11, respectively. When the worker observes that the string assembly has been raised to the worker's operating height, the worker controls the lifting cylinder 1 to close. Finally, the worker uses the string assembly to thread the mesh-like elastic string into the racket.

[0044] In this process, when the worker threads the elastic string into the racket through the stringing assembly, the stringing assembly applies a reaction force to the platform 5. This reaction force is then transmitted to the lifting cylinder 6. Since the left guide rail 10 and the rear guide rail 11 are located on the left and rear sides of the fixed cylinder 9, respectively, and the left slider 12 and the rear slider 13 are slidably mounted on the left guide rail 10 and the rear guide rail 11, respectively, and the left slider 12 and the rear slider 13 are fixed to the left inner wall and the rear inner wall of the lifting cylinder 6, respectively, the reaction force can be resisted from two directions. This effectively prevents the platform 5 from shaking due to the reaction force, and thus effectively prevents the stringing assembly from shaking during operation, thereby improving the stringing quality of the racket. Therefore, this lifting assembly, compared to... Figures 1-2 The lifting assembly shown has the characteristic of higher stability.
