[0002] Gear shaping machine is a metal cutting machine tool that uses gear shaping cutters to process internal, external spur and helical cylindrical gears and other toothed parts according to the generating method.

[0003] A Chinese utility model patent with authorization announcement number CN216780556U discloses a gear shaping machine, including a machine body, an inner bottom wall of the machine body is provided with a collecting tank, two groups of return pipes are clamped at the bottom of the machine body, the interior of each group of return pipes is fixedly connected to the interior of the collecting tank, a collecting bucket is clamped at the outer surface of each group of return pipes, a frame is clamped at the interior of the machine body, two handles are fixedly connected to the front of the frame, and a filter is clamped at the interior of the frame; however, the prior art still has the following technical problems: first, the debris generated by the workpiece during processing will splash and cannot all reach the filter, resulting in incomplete chip removal; second, in the process of cleaning the debris and replacing the coolant, the gear shaping machine needs to be stopped, the filter is manually pulled out and the debris is cleaned, and then a plug is plugged on the return pipe to remove the collecting bucket. Manual operation is relatively cumbersome, time-consuming and labor-intensive, and work efficiency is low. Utility Model Content

[0004] The utility model aims to provide a chip removal device for a gear shaping machine, which has the effects of improving working efficiency, reducing costs and efficiently collecting debris.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a chip removal device of a gear shaping machine, comprising a chassis, a gear shaping cutter is arranged on the top of the chassis, the chassis is rotatably connected to a fixture table corresponding to the gear shaping cutter, the chassis is also connected to a nozzle corresponding to the gear shaping cutter, the bottom end of the chassis is inclined and provided with a discharge port, the chassis is connected to a filter box at the discharge port, the bottom end of the filter box is connected to a liquid tank, the chassis is rotatably connected to a first rotating shaft, the first rotating shaft is linked to the fixture table and fixedly connected to a crank, the filter box is detachably connected to a filter plate, a push plate is slidably connected to the filter plate in the filter box, the push plate is hinged with a connecting rod, and the end of the connecting rod away from the push plate is hinged to the end of the crank away from the first rotating shaft.

[0006] By adopting the above technical scheme, by tilting the bottom end of the chassis, the bottom end of the filter box can be set to a conical bottom. When the gear cutter processes the workpiece, a large amount of debris will be generated, and the debris will splash as the fixture table rotates. At the bottom end of the cone, the debris is smoothly slid out from the discharge port at the bottom end of the chassis under the action of gravity and cooling tools such as coolant, thereby solving the problem of incomplete chip removal caused by chip splashing. By setting up the filter box and linking the first rotating shaft with the fixture table, when the device processes the workpiece, the fixture table drives the workpiece to rotate at a required angle. At this time, the fixture table will rotate simultaneously with the first rotating shaft, and the first rotating shaft drives the push plate to move in the filter box through the crank and the connecting rod, thereby pushing the debris out of the filter box, which can realize the simultaneous cleaning of debris and workpiece processing, and there is no need to manually clean the debris, thereby improving work efficiency.

[0007] The utility model is further configured as follows: the chassis is equipped with a motor, the output end of the motor is connected to the first rotating shaft, and the first rotating shaft is coaxially connected to the output end of the motor.

[0008] The utility model is further configured as follows: the chassis is rotatably connected to a second rotating shaft, the fixture table is coaxially arranged on the second rotating shaft, the first rotating shaft is coaxially arranged with a driving wheel, the second rotating shaft is coaxially arranged with a driven wheel, and the driving wheel and the driven wheel are both configured as pulleys and connected by belts.

[0009] By adopting the above technical solution, by coaxially connecting the first rotating shaft with the output end of the motor, by setting the second rotating shaft, the driving wheel and the driven wheel are coaxially set on the first rotating shaft and the second rotating shaft respectively, and the driving wheel and the driven wheel are both set as pulleys. Under the transmission of the pulley, the belt will more smoothly transmit the power of the first rotating shaft to the second rotating shaft, thereby achieving the purpose of linkage between the first rotating shaft and the second rotating shaft and stable power transmission.

[0010] The utility model is further configured as follows: the radius of the driving wheel is much smaller than the radius of the driven wheel.

[0011] By adopting the above technical solution, by setting the radius of the driving wheel to be much smaller than the radius of the driven wheel, the fixture table drives the workpiece to rotate intermittently at a certain angle. When the motor drives the first rotating shaft to rotate, the first rotating shaft rotates at a larger rotation angle, which will cause the second rotating shaft to rotate at a relatively small angle. This can achieve the purpose of the first rotating shaft driving the push plate to move a longer length in the filter box while the first rotating shaft and the second rotating shaft are linked, thereby achieving a higher chip removal efficiency, and at the same time the second rotating shaft drives the workpiece to rotate at a smaller angle.

[0012] The utility model is further configured as follows: the liquid tank is connected to the spray pipe via a liquid pipe.

[0013] By adopting the above technical solution and setting up a liquid pipe, when the device processes a workpiece, the sprinkler draws liquid from the liquid tank and sprays it out through the nozzle. In an assembly line operation, the sprinkler can continuously draw liquid from the liquid tank, thereby realizing the recycling of coolant or cooling oil, reducing production costs and improving work efficiency.

[0014] The utility model is further configured as follows: the filter box is fixedly provided with a collecting port, and the collecting port is connected to a collecting box for collecting debris.

[0015] The utility model is further configured as follows: a first slide groove is provided on the inner side of the filter box, both ends of the filter plate are embedded in the first slide groove, a second slide groove is provided in the filter box above the first slide groove, and protrusions for embedding in the second slide groove are provided on both sides of the push plate.

[0016] By adopting the above technical solution, by setting the first slide groove, the filter plate is slidably connected to the first slide groove, so that the purpose of the filter plate being detachably connected to the filter box can be achieved; by setting the second slide groove, the push plate is slidably connected to the second slide groove through the protrusions on both sides, and when the first shaft drives the push plate to slide in the filter box, the second slide groove can play a guiding role to ensure the smooth sliding of the push plate, so as to achieve the purpose of the push plate stably pushing the debris off the filter plate.

[0017] The utility model is further configured as follows: the filter box is threadedly connected with a locking screw at the collection port, the filter plate is provided with a threaded hole corresponding to the locking screw, and the locking screw is used to fix the filter plate to the filter box.

[0018] By adopting the above technical solution and setting a locking screw, when the filter plate is installed on the filter box, the locking screw is connected to the threaded hole on the filter plate, and when the first shaft drives the push plate to scrape debris off the filter plate, the push plate will not push the filter plate off the filter box. When the filter plate needs to be replaced after working for a long time, or when the filter plate needs to be replaced because the workpiece is more precise and finer debris needs to be filtered, it is only necessary to loosen the tightening screw and pull out the filter plate, thereby achieving the purpose of detachably connecting the filter plate.

[0019] The beneficial effects of the utility model are as follows: when the gear shaping cutter processes the workpiece, the generated debris will slide out smoothly from the discharge port along the conical ground at the bottom of the chassis, effectively preventing the problem of incomplete collection caused by debris splashing, and the debris is pushed by the push plate in the filter box and discharged from the collection port. The push plate and the fixture table are linked to make it possible to clean the debris and process the workpiece at the same time, and the nozzle can continuously recycle the coolant or cooling oil, which has the effects of improving work efficiency, reducing costs and efficiently collecting debris.
