Description

Technical Field

[0001] The utility model relates to the technical field of gear chamfering, in particular to a gear cyclic chamfering device. Background Art

[0002] Gear cyclic chamfering refers to the processing of arcs at a certain radius at the top and root of the gear teeth. This processing is repeated. Its main purpose is to reduce the stress concentration between the tooth surface and the tooth root, reduce the tooth surface contact stress and friction loss, and thus increase the service life of the gear. Circular chamfering helps to reduce the impact and noise when the gears are meshing, and increase the stability of the gear transmission.

This device is reasonably designed, which is conducive to improving the efficiency of gear chamfering processing and is suitable for chamfering and grinding of gears of various diameters, and can collect and clean metal debris generated during the chamfering and grinding process. Although this patent solves the problems of simultaneous grinding on both sides of the gear, being applicable to gears of various diameters, and collecting metal debris, the debris cleaning part adopts an adsorption method, which has the disadvantages of low yield, unstable performance, and inability to operate continuously. At the same time, the component spacing of the fixed gear cannot be adjusted, which makes it unsuitable for gears of different thicknesses, further resulting in limited processing accuracy, increased safety hazards, and shortened equipment life. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a gear cyclic chamfering device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A gear circulation chamfering device comprises a support frame, two first hydraulic rods are fixed on the top of the support frame, the telescopic ends of the two first hydraulic rods are fixedly connected to a fixing plate, a chamfering mechanism is connected between the fixing plate and the support frame, the chamfering mechanism is located between the two first hydraulic rods, two second hydraulic rods are provided at the upper end of the fixing plate, the telescopic ends of the two second hydraulic rods are fixedly connected to a fixing block, a driving mechanism connected to the fixing block is provided between the two second hydraulic rods, a rotating rod is penetrated at the upper end of the fixing plate, the upper end of the rotating rod is connected to the driving mechanism, the lower end of the rotating rod extends to the inside of the chamfering mechanism and is connected to the fixing mechanism, and a collecting mechanism connected to the chamfering mechanism is provided inside the support frame.

[0009] As a further improvement of the utility model, the fixing mechanism includes a lower fixing plate threadedly sleeved on the lower end of the rotating rod, and an upper fixing plate fixedly sleeved on the rotating rod is provided above the lower fixing plate.

[0010] As a further improvement of the utility model, the collecting mechanism includes a frame body arranged under the supporting frame, one side of the frame body is open and a collecting box is slidably provided, a pipe is passed through the supporting frame, the upper end of the pipe is connected to the lower end of the lower chamfered cover, and the lower end of the pipe passes through the frame body and is connected to the collecting box.

[0011] As a further improvement of the utility model, a plurality of thread grooves are circumferentially formed on the upper fixing plate, and the internal threads of the thread grooves are plugged with second bolts.

[0012] Beneficial effects of the utility model:

[0013] By setting a first hydraulic rod and an upper chamfer cover, the fixed plate is lifted by starting the first hydraulic rod, and when the fixed plate is lifted, the upper chamfer cover fixed at the bottom thereof will be lifted together. When the upper chamfer cover is lifted, the gears on the internal fixing mechanism thereof can be replaced.

[0015] By setting up a fixing mechanism, the lower fixing plate is removed from the rotating rod by rotating it, and then the gear is put on the rotating rod, and then the lower fixing plate is screwed to the rotating rod again, and then the first bolt is rotated. Since the first bolt and the upper fixing plate are in a threaded connection relationship, and the upper fixing plate is arranged above the lower fixing plate and fixedly sleeved on the rotating rod, the first bolt will press down and contact the gear to generate friction when rotating, thereby achieving the purpose of fixing the gear, simplifying the gear replacement process, improving work efficiency, and ensuring the stability and safety of the gear.

The U-shaped frame 6 is driven to move up and down by the second hydraulic rod 4. Since the rotating rod 8 is fixed to the bottom of the U-shaped frame 6, when the U-shaped frame 6 moves up and down, the rotating rod 8 moves up and down synchronously. The up and down movement of the rotating rod 8 will drive the fixing mechanism to move up and down, and the gear located on the fixing mechanism will also move up and down accordingly. When the gear moves up and down, it contacts the upper chamfering cover 9 and the lower chamfering cover 10 arranged up and down to perform the chamfering operation. The fixing mechanism includes a lower fixing plate 15 threadedly sleeved on the lower end of the rotating rod 8. A plurality of thread grooves are opened circumferentially on the upper fixing plate 14, and the internal thread grooves of the thread grooves are screwed. The first bolt 16 is inserted into the thread, and an upper fixing plate 14 fixedly sleeved with the rotating rod 8 is provided above the lower fixing plate 15.

Since the first bolt 16 and the upper fixing plate 14 are in a threaded connection relationship, and the upper fixing plate 14 is arranged above the lower fixing plate 15 and fixedly sleeved on the rotating rod 8, the first bolt 16 will press down and contact the gear to generate friction when it rotates, so as to achieve the purpose of fixing the gear. After the gear is fixed, the first hydraulic rod 2 is started again to reset the fixing plate 3 so that the upper chamfered cover 9 is restored. The upper chamfering cover 9 is reset to prevent debris from splashing during chamfering, and the motor 7 is started immediately. The motor 7 rotates to drive the rotating rod 8, and the rotating rod 8 drives the gear on the fixed mechanism to rotate. Then the second hydraulic rod 4 is started to drive the U-shaped frame 6 to move up and down. Since the rotating rod 8 is fixed at the bottom of the U-shaped frame 6, when the U-shaped frame 6 moves up and down, the rotating rod 8 moves up and down synchronously. The up and down movement of the rotating rod 8 drives the fixing mechanism to move up and down, and the gear on the fixing mechanism also moves up and down accordingly. When the gear moves up and down, it contacts the upper chamfering cover 9 and the lower chamfering cover 10 arranged above and below to perform chamfering operations. The debris generated during chamfering will fall due to its own weight and fall into the collection box 12 through the pipe 11.
