Background

In modern manufacturing, metal gears are used as key transmission components of various mechanical devices, and the processing quality of the metal gears directly influences the performance, the precision and the service life of the devices. With the increasing demand of manufacturing industry for high-precision and high-performance mechanical equipment, more stringent requirements are put on the machining precision and surface quality of metal gears.

Working principle:

the feeding and discharging mechanical arm 4 of the first station is started, and the clamping jaw at the tail end of the mechanical arm accurately identifies the position and the gesture of the gear to be processed through the sensor. The clamping jaw moves according to a preset program and a path to accurately grasp the gear to be processed.

The feeding and discharging mechanical arm 4 carries the grabbing gear and stably moves to the upper side of the turntable assembly 3. At this time, the vacuum chuck 34 on the turntable body 31 is in a waiting state, the vacuum pump 35 is started in advance, and a certain negative pressure is formed in the vacuum chuck 34.

The loading and unloading mechanical arm 4 slowly descends the gear to the corresponding position of the vacuum clamp 34, and after the gear reaches the preset position, the gear is quickly adsorbed by the vacuum clamp 34, so that the gear is firmly fixed on the turntable body 31. Subsequently, the loading and unloading mechanical arm 4 releases the clamping jaw and returns to the initial position to wait for the next loading instruction.

The drive motor is started according to the set rotation speed and the set running time to drive the cam divider 32 to run. The cam divider 32 converts the continuous rotation of the driving motor into precise intermittent rotation by a special cam mechanism, and the output end thereof drives the turntable body 31 to rotate at predetermined angles and time intervals.

The turntable body 31 smoothly rotates the gear fixed to the vacuum jig 34 from the first station to the second station by the cam divider 32. The sanding polishing assembly 5 begins to operate at the same time as the gear reaches the second station.

The X-axis moving mechanism 51 fixed to the table 2 is started, and a motor therein drives a transmission device such as a screw or a timing belt to move the X-axis moving base 52 in the X-axis direction. The X-axis moving seat 52 monitors its own position in real time by a sensor and precisely adjusts to a proper X-axis coordinate position according to a preset program and processing parameters.

When the X-axis moving seat 52 reaches a predetermined position, the Y-axis moving mechanism 53 starts to operate. The Y-axis moving mechanism 53 operates in a similar manner to the X-axis moving mechanism 51 in that the Y-axis moving mechanism 53 mounted on the output end of the X-axis moving base 52 is moved in the Y-axis direction by a motor-driven transmission, and is also precisely adjusted to the corresponding Y-axis coordinate position by a sensor.

Next, the Z-axis moving mechanism 54 is activated, which drives movement in the Z-axis direction, so that the polishing head 55 mounted on the output end of the Y-axis moving mechanism 53 gradually approaches the gear surface. In the approaching process, the Z-axis moving mechanism 54 precisely controls the contact pressure and distance between the polishing head 55 and the gear surface according to the distance information fed back by the sensor.

When the polishing head 55 and the gear surface reach a proper working distance and pressure, the polishing head 55 starts to rotate at a high speed, and one side of the gear is polished. In the polishing process, the X-axis moving mechanism 51, the Y-axis moving mechanism 53 and the Z-axis moving mechanism 54 can finely adjust the position of the polishing head 55 in real time according to preset processing paths and parameters, so as to ensure comprehensive, uniform and accurate polishing of the gear surface.

After finishing the polishing of one side, the turntable body 31 continues to rotate under the drive of the cam divider 32, and the gear is smoothly rotated to the third station. At this time, the turn-over mechanism 6 starts to operate.

The motor 631 of the turn-over mechanism 6 is started, and the output shaft of the motor 631 drives the driving synchronous pulley 632 to rotate at a high speed. The driving synchronous pulley 632 transmits power to the driven synchronous pulley 634 through the synchronous belt 633, and the driven synchronous pulley 634 is fixedly mounted on the rotating shaft 62, thereby driving the rotating shaft 62 to rotate. The rotary shaft 62 rotates and the mounting plate 64 mounted at the other end of the rotary shaft 62 rotates. After the mounting plate 64 is rotated to a proper position, the lifting cylinder 661 fixed to the roll-over stand 65 is activated. The piston rod of the elevating cylinder 661 is extended to push the elevating plate 662 downward along the guide rail 664 on the roll-over stand 65. As the elevating plate 662 descends, the clamping cylinder 67 fixed to the elevating plate 662 gradually approaches the gear. When the clamping cylinder 67 reaches the proper position, the clamping cylinder 67 is activated and the clamping arms 68 at its output open and accurately clamp the gear.

After the clamping arm 68 clamps the gear, the piston rod of the lifting cylinder 661 is retracted, driving the lifting plate 662, the clamping cylinder 67 and the clamped gear to rise together, so that the gear is separated from the vacuum clamp 34 on the turntable body 31. The motor 631 is started again, and the rotating shaft 62 is driven to rotate 180 degrees through the synchronous belt transmission mechanism, so that the clamped gear can be turned over.

After the gear is turned over, the piston rod of the lifting cylinder 661 stretches out again, and the gear is slowly lowered to the position corresponding to the vacuum clamp 34 on the turntable body 31. When the gears are in place, the clamping cylinder 67 releases the clamping jaw, and the lifting cylinder 661 drives the lifting plate 662 and other components to lift back to the initial position. At the same time, the vacuum clamp 34 again adsorbs the gear, ensuring the stability of the gear during subsequent processing.

The turntable body 31 rotates the gear which completes the turn-over from the third station to the fourth station under the drive of the cam divider 32. At this time, the sanding polishing assembly 5 of the fourth station starts to operate, and the operation is similar to that of the sanding polishing assembly 5 of the second station. The X-axis moving mechanism 51, the Y-axis moving mechanism 53, and the Z-axis moving mechanism 54 cooperate to precisely adjust the position of the polishing head 55 according to preset processing parameters and paths so that the polishing head 55 is brought close to the other face of the gear. When the polishing head 55 and the gear surface reach a proper working state, the polishing head 55 rotates at a high speed, and the other surface of the gear is polished. In the polishing process, the three-axis moving mechanism can finely adjust the position of the polishing head 55 in real time so as to ensure high-quality polishing of the other surface of the gear.

After the gears finish the polishing of both sides, the turntable body 31 is rotated back to the first station by the drive of the cam divider 32. At this time, the loading and unloading mechanical arm 4 is started again, and the clamping jaw moves to the position above the gear on the turntable body 31, which is finished to be processed. The clamping jaw of the loading and unloading mechanical arm 4 accurately grabs the finished gear, and the vacuum clamp 34 stops adsorbing. The loading and unloading mechanical arm 4 lifts up with the finished gear and moves to a designated unloading position, and the finished gear is placed on a corresponding collecting device or a conveyer belt.

After the blanking is completed, the feeding and blanking mechanical arm 4 immediately returns to the feeding position, and according to the operation flow of the feeding stage, a new gear to be processed is grabbed and placed on the vacuum clamp 34 on the turntable body 31, so that one complete cycle operation is completed. The equipment can continuously repeat the working process, so that continuous and efficient grinding and polishing processing of the metal gear is realized.

The above examples illustrate only certain embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model, it being understood that variations and modifications can be made by those skilled in the art without departing from the spirit of the utility model, which is within the scope of the utility model, and the appended claims shall therefore be construed as defining the scope of the utility model.
