Description

Technical Field

[0001] This utility model relates to the field of gears, and in particular to a gear pairing device for detecting gear meshing degree. Background Technology

[0002] In the prior art, a gear is a mechanical component with continuous teeth on its rim that can continuously mesh and transmit motion. Gears are the main components in most transmission systems, and their ubiquity is very high. Many devices use gears. Currently, when gears are stored in a gear warehouse for a long time or used for a long time, the specification and model labels on the gears will wear off, making it impossible to accurately identify the gear model information. When gears are needed to assemble equipment, it is not possible to quickly select the corresponding meshing gears in the gear warehouse, and it is not easy to match gears with different shaft hole diameters and thicknesses. Utility model CN220356660U discloses a gear pairing device for detecting gear meshing degree, including a base. The upper end of the base is provided with opposing vertical plates. The upper ends of the vertical plates are provided with top plates on both sides. The upper end of the base is provided with a box and a second vertical plate. The box contains a motor. The output end of the motor is provided with a shaft that passes through one side of the box. One side of the second vertical plate is provided with an electric push rod. One end of the shaft and the first electric push rod is respectively fixed to a clamping plate and a connecting plate. One side of the first connecting plate is provided with a rotating shaft. The rotating shaft is provided with a connecting rod. One side of the connecting rod is fixed to a clamping plate. One side of the second clamping plate is provided with a protrusion. The second clamping plate has a through groove that mates with the protrusion. The lower end of the top plate is provided with a second electric push rod. The lower end of the second electric push rod is provided with a lifting plate. However, it restricts the position of the two sets of gears by several push rods, which makes the installation of the gears too cumbersome. When matching gears, it is necessary to be efficient and disassemble the gears quickly. At the same time, it is difficult to test whether gears with different diameters are compatible.

The fixed device is arranged in two sets, one set rotating on the worktable and the other set rotating at the working end of the moving device. The gear has a slot.

[0007] As a further improvement to the above technical solution: the moving component includes a rotating rod, a slider threadedly connected to the rotating rod, a limiting rod that engages in the third groove, and a knob for facilitating the rotation of the rotating rod; the rotating rod passes through the first groove; the limiting rod is disposed on the slider; a plurality of limiting rods are arranged in a circumferential array and the number of limiting rods corresponds to the number of the second block; the actuating end of the limiting rod slides within the third groove; the knob is disposed on the rotating rod and protrudes from the first block.

[0008] As a further improvement to the above technical solution: a rubber component is provided on the end face of the clamping rod facing the groove; the rubber component presses against the groove while preventing indentations on the inside of the groove.

[0012] The innovative adjustable fixing and moving devices work in tandem to effectively improve the efficiency and applicability of gear pairing detection. The device employs two sets of relatively movable rotating fixing devices, one of which is mounted on a moving platform with a fourth slot. Precise displacement adjustment is achieved through drive rods and button control, quickly adapting to the meshing distance requirements of gears with different diameters. The fixing device innovatively adopts a three-stage linkage clamping structure: the rotating rod drives the limiting rod to slide along the inclined track of the third slot, driving the second block to radially extend and retract within the second slot. This causes the circumferential array of clamping rods to simultaneously press against the sidewall of the gear hole slot. Combined with the interference fit design of the rubber components, this ensures rapid gear clamping while avoiding indentations on the hole wall. This structure overcomes the limitations of traditional multi-push-rod step-by-step operation, achieving single-action synchronous clamping of gears with different diameters, significantly shortening clamping time and maintaining a uniform distribution of clamping force. The overall device combines multiple advantages such as rapid gear positioning, convenient axial spacing adjustment, and damage protection, making it particularly suitable for rapid pairing detection and model identification of warehouse gears, providing an efficient and reliable solution for gear meshing detection.

The working end of the fixed device 2 abuts against the side wall of the slot 31.

[0021] The fixing device 2 includes a first block 21, a second block 22 that slides inside the first block 21, a clamping rod 23 that abuts against the inner side wall of the slot 31, and a moving member 24 that drives the second block 22 to slide. A first slot 211 is formed inside the first block 21. The moving member 24 is disposed inside the first slot 211. A plurality of second slots 212 are formed on the side wall of the first slot 211. The second block 22 slides inside the second slots 212. The clamping rod 23 is disposed on the second block 22 and moves synchronously with the second block 22. A third slot 221 is formed inside the second block 22. The third slot 221 is inclined at an angle. The working end of the moving member 24 slides inside the third slot 221.

[0022] The movable component 24 includes a rotating rod 241, a slider 242 threadedly connected to the rotating rod 241, a limiting rod 243 that engages in the third groove 221, and a knob 244 for facilitating the rotation of the rotating rod 241; the rotating rod 241 passes through the first groove 211; the limiting rod 243 is disposed on the slider 242; several limiting rods 243 are arranged in a circumferential array and the number of limiting rods 243 corresponds to the number of the second block 22; the actuating end of the limiting rod 243 slides within the third groove 221; the knob 244 is disposed on the rotating rod 241 and protrudes from the first block 21.

[0023] A rubber component 231 is provided on the end face of the clamping rod 23 facing the groove 31; the rubber component 231 presses against the groove 31 while preventing indentations on the inside of the groove 31.
