Description

Technical Field

[0001] This utility model relates to the field of gear positioning device technology, and in particular to a gear positioning device using a cylinder. Background Technology

[0002] Gears are mechanical components with regularly arranged teeth on their rims. They achieve the cross-axis transmission of rotational motion and power through inter-tooth meshing. As a core component in the field of mechanical transmission, their application can be traced back to the ancient Greek water clock. The rise of the clockmaking industry in the 14th century promoted the development of precision gear technology. The emergence of the gear cutting method in the 19th century completely changed the way gears are manufactured, making involute gears the modern industrial standard. The core functions of gears are reflected in three aspects: First, they realize the conversion of speed and torque through different combinations of the number of teeth. For example, automobile gearboxes use multi-stage gear sets to reduce the engine speed to the range required by the wheels. Second, they change the direction of motion. For example, bevel gear sets can turn the power of the horizontal axis to the vertical axis to drive the spindle of a machine tool. Third, they precisely control the trajectory of motion. Micron-level gear sets in clocks ensure the synchronous operation of the hour and minute hands. The positioning accuracy directly affects the gear transmission performance. If the axial positioning is insufficient, the gear will have axial movement during operation, resulting in uneven wear of the tooth surface, increased noise, or even tooth breakage. However, the existing positioning devices have fixed positions and can only position gears of a single diameter, which has certain limitations. In view of this, this utility model is proposed. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a gear positioning device using a cylinder, which can position gears of different diameters. The hydraulic cylinder can drive the mounting plate to rise and fall, thereby driving the positioning component to rise and fall. Under the action of the snap-fit ​​cone, the positioning component can be moved, thereby adjusting the position of the positioning component. This makes the positioning component suitable for positioning gears of different diameters, thus improving the versatility of this structure.

[0004] The technical solution adopted by this utility model is as follows: it includes a base plate and a fixed box. The lower end of the fixed box is fixedly installed with a support foot. Both the base plate and the support foot are fixedly connected to the external usage location. The base plate is located on one side of the fixed box. A hydraulic cylinder is fixedly installed on the upper end of the base plate. An mounting plate is fixedly installed on the upper end of the hydraulic cylinder. A through hole is opened on one side of the upper end of the mounting plate. Positioning components are arranged in a circumferential array inside the through hole. A snap-fit ​​cone is installed on the upper end of the fixed box. The positioning components are snap-fitted to the snap-fit ​​cone. In use, the structure is first placed at the usage location. Then, the gear is placed on the snap-fit ​​cone. At this time, the gear is located in the middle of the positioning components. Then, the hydraulic cylinder drives the mounting plate to rise and fall, thereby driving the positioning components to rise and fall. Since the positioning components are snap-fitted to the snap-fit ​​cone, the positioning components can be driven to move laterally. The positioning components can complete the positioning of the gear.

[0005] Preferably, to facilitate the installation of the positioning component, a connecting ring is fixedly installed on one side of the upper end of the mounting plate. The connecting ring is installed on the outside of the through hole, and an mounting ring is fixedly installed on the upper end of the connecting ring. The inner diameters of the connecting ring and the mounting ring are the same as the diameter of the through hole, and the positioning component is located inside the connecting ring and the mounting ring.

[0006] Preferably, in order to install the positioning component inside the through hole, the positioning component includes a miniature multi-section telescopic rod, which is fixedly installed in a circumferential array inside the through hole and on the inner wall of the mounting ring.

[0007] Preferably, in order to position the gear, an arc-shaped positioning plate is fixedly installed at the other end of the miniature multi-section telescopic rod, and the arc-shaped positioning plate is arranged in a circumferential array on the outside of the snap-fit ​​cone.

[0008] Preferably, in order to enable the rotating shaft to rotate in the rotating groove, a rotating groove is provided in the middle of the arc-shaped positioning plate. The rotating groove is a through groove, and the rotating shaft is rotatably engaged in the rotating groove.

[0009] Preferably, in order to enable the connecting rod to rotate, a connecting rod is fixedly installed on the rotating shaft, one end of the connecting rod is rotatably engaged in the rotating groove, and a locking block is fixedly installed on the other end of the connecting rod.

[0010] Preferably, in order to enable the positioning component to move laterally during lifting and lowering, thereby positioning gears of different diameters, the outer circumferential array of the locking cone is provided with locking grooves, and the locking block is slidably locked in the locking grooves.

[0011] The beneficial effects of this utility model are: the hydraulic cylinder can drive the mounting plate to rise and fall, thereby driving the positioning component to rise and fall; under the action of the snap-fit ​​cone, the positioning component can be moved, thus adjusting the position of the positioning component, making it suitable for positioning gears of different diameters, and improving the versatility of this structure.

[0013] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-5 As shown, this embodiment provides a gear positioning device using a cylinder, including a base plate 1 and a fixed box 2. A support foot 3 is fixedly installed at the lower end of the fixed box 2. Both the base plate 1 and the support foot 3 are fixedly connected to the external usage location, and the base plate 1 is located on one side of the fixed box 2. A hydraulic cylinder 4 is fixedly installed at the upper end of the base plate 1, and an mounting plate 5 is fixedly installed at the upper end of the hydraulic cylinder 4. A through hole 6 is opened on one side of the upper end of the mounting plate 5. Positioning components 7 are arranged in a circumferential array inside the through hole 6. A snap-fit ​​cone 8 is installed at the upper end of the fixed box 2. The positioning components 7 are snap-fitted to the snap-fit ​​cone 8. In use, the device is first placed at the usage location, and then the gear is placed on the snap-fit ​​cone 8. At this time, the gear is located in the middle of the positioning components 7. Then, the hydraulic cylinder 4 drives the mounting plate 5 to rise and fall, thereby driving the positioning components 7 to rise and fall. Since the positioning components 7 are snap-fitted to the snap-fit ​​cone 8, the positioning components 7 can be driven to move laterally. The positioning components 7 can complete the positioning of the gear.

[0014] As a technical optimization solution of this utility model, specifically as follows: Figure 1As shown, a connecting ring 9 is fixedly installed on one side of the upper end of the mounting plate 5. The connecting ring 9 is installed on the outside of the through hole 6. A mounting ring 10 is fixedly installed on the upper end of the connecting ring 9. The inner diameter of the connecting ring 9 and the mounting ring 10 is the same as the diameter of the through hole 6. The positioning component 7 is located inside the connecting ring 9 and the mounting ring 10. The positioning component 7 includes a miniature multi-section telescopic rod 701. The miniature multi-section telescopic rod 701 is circumferentially arrayed and fixedly installed inside the through hole 6 and on the inner wall of the mounting ring 10. An arc-shaped positioning plate 702 is fixedly installed on the other end of the miniature multi-section telescopic rod 701. The arc-shaped positioning plate 702 is circumferentially arrayed and arranged on the outside of the snap-fit ​​cone 8. A rotating groove 703 is opened in the middle of the arc-shaped positioning plate 702. The rotating groove 703 is a through groove, and a rotating snap-fit ​​device is rotatably engaged in the rotating groove 703. A connecting rod 705 is fixedly installed on the rotating shaft 704. One end of the connecting rod 705 is rotatably engaged in the rotating groove 703, and the other end of the connecting rod 705 is fixedly installed with a locking block 706. The outer circumferential array of the locking cone 8 has locking grooves 11. The locking block 706 is slidably engaged in the locking grooves 11. In use, the gear is placed on the upper end of the locking cone 8, and then the hydraulic cylinder 4 drives the mounting plate 5 to rise and fall, thereby driving the positioning component 7 to rise and fall. Since the locking block 706 is engaged in the locking grooves 11, the arc-shaped positioning plate 702 can be moved along the locking grooves 11 through the connecting rod 705. Since the locking grooves 11 are opened at an angle, the arc-shaped positioning plate 702 can move laterally during the rise and fall, thereby completing the positioning of gears of different diameters.
