Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading structures, in particular to a loading and unloading mechanism of a hobbing machine. Background Technique

[0002] The loading and unloading mechanism of a hobbing machine is an important part of the hobbing machine. Its design aims to improve the efficiency and automation level of gear processing. As one of the most widely used machine tools in gear processing, the hobbing machine not only plays an important role in the traditional machinery industry but also occupies an important position in modern automated manufacturing.

[0003] In the existing loading and unloading mechanism of a hobbing machine, usually, a conveyor motor drives a conveyor belt to transport the parts to be processed to the working area of the loading and unloading mechanism. When the parts reach the designated position, the first servo motor in the loading and unloading mechanism starts. The two jaws approach each other and firmly grip the parts by the forward rotation of the bidirectional lead screw. After the drive motor starts, the parts in the jaws are rotated above the hobbing machine chuck by the rotation of the transmission column. The second servo motor drives the unidirectional lead screw, so that the loading and unloading mechanism holding the parts moves downward to a suitable position above the hobbing machine chuck. Then the first servo motor drives the bidirectional lead screw to reverse, and the jaws release the parts and accurately place them on the hobbing machine chuck for processing. After the processing is completed, the drive motor is activated again to rotate the empty jaws above the hobbing machine chuck, and the jaws grip the processed parts again. However, this mechanism has certain defects in use. In the actual loading and unloading process, this device performs loading and unloading with a single-direction component. Since only one workpiece can be processed each time, the device is often idle during the waiting period for the next workpiece to be loaded or unloaded, which further reduces the utilization rate and production efficiency of the device.

[0018] 1. For the loading and unloading mechanism of the hobbing machine provided by the present utility model, the operator places the frame at the processing window of the hobbing machine table. There are an adjustment component, a rotation component, and a loading and unloading mechanism installed on the frame.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a loading and unloading mechanism of a hobbing machine. There is a hobbing machine table 100, and a frame 200 is installed at the side end of the processing window of the hobbing machine table 100. A through groove 201 is opened on the upper end surface of the frame 200; an adjusting assembly 300 is installed in the through groove 201 provided in the frame 200. The adjusting assembly 300 includes a fixed groove 301 installed in the through groove 201, and a bearing plate 304 is installed in the fixed groove 301; two sets of loading and unloading mechanisms 500 are assembled on the bearing plate 304 at 90°. Each of the two sets of loading and unloading mechanisms 500 includes an electric drive component 502, a movable collar 503, an electrically contractible rod 504, and a gripper 505; a rotating assembly 400 is installed in the inner ring of the bearing plate 304. The rotating assembly 400 includes a driving component 402 and a turntable 401 installed in the inner cavity of the bearing plate 304; two sets of material placement components 600 are respectively installed on both sides of the through groove 201 provided in the frame 200.

[0032] In an embodiment of the present application, the electric drive component 502 is specifically an electric drive rod. The electric drive component 502 is installed on the turntable 401 through a fixing plate 501. Multiple groups of positioning holes are provided on the outer ring of the fixing plate 501. The fixing plate 501 detachably installs the electric drive component 502 on the turntable 401 through positioning bolts. The operator places the frame 200 at the processing window of the hobbing machine table 100. An adjusting component 300, a rotating component 400, and a loading and unloading mechanism 500 are installed on the frame 200. After the hobbing machine table 100 is started, the electric drive component 502 is started. Since the electric drive component 502 is specifically an electric drive rod, and the electric drive rod is a device that converts the rotational motion of an electric motor into a linear reciprocating motion, which is a mature existing technology and will not be introduced in detail here. One end of the moving collar 503 is installed with a gripper 505. The electric drive component 502 drives the moving collar 503 to move up and down, thereby realizing the adjustment of the vertical height of the gripper 505. After the gripper 505 grips the workpiece, after the electric drive component 502 drives the gripper 505 to adjust a certain height, the driving component 402 is started. Since the driving component 402 is specifically a forward and reverse motor, it can drive the turntable 401 to rotate. Through the rotation of the turntable 401, another loading and unloading mechanism 500 is rotated to the material placing component 600. Then the above operation is repeated. After the gripper 505 grips the workpiece, the electric drive component 502 adjusts the height of another gripper 505 by a certain amount. At this time, by starting the electric contraction rod 504, the gripper 505 is driven to move. After the gripper 505 moves to the cutting processing area, the height of the gripper 505 is adjusted by the electric drive component 502 again. Finally, the workpiece is placed in the cutting processing area by controlling the gripper 505, and then the gripper 505 is retracted by the electric contraction rod 504. At this time, by starting the driving component 402, another loading and unloading mechanism 500 holding the workpiece is rotated to the processing window of the hobbing machine table 100. Since the two loading and unloading mechanisms 500 are at a 90° angle, when one loading and unloading mechanism 500 holding the workpiece rotates to the processing window of the hobbing machine table 100, the other loading and unloading mechanism 500 rotates above the material placing component 600. Then the above operation is repeated, and the clamping and feeding work of the workpiece can be completed. By setting the two loading and unloading mechanisms 500, the loading and unloading efficiency can be effectively improved, thereby improving the processing efficiency.

[0033] In an embodiment of the present application, an adjustment component 302 is installed on one side of the frame 200. The adjustment component 302 is specifically a motor. The output end of the adjustment component 302 is installed with a lead screw 303. A carrier plate 304 is sleeved on the lead screw 303. By providing the adjustment component 302 as a motor specifically, during use, driven by the adjustment component 302, the lead screw 303 is driven to rotate. By the rotation of the lead screw 303, the carrier plate 304 can be driven to move back and forth in the fixed slot 301. By the back-and-forth movement of the carrier plate 304, the two loading and unloading mechanisms 500 installed on the carrier plate 304 are driven to move back and forth. By the back-and-forth movement of the two loading and unloading mechanisms 500, the workpieces in the material placement components 600 on the left and right sides can be clamped.

[0034] In an embodiment of the present application, an annular limiting protrusion is provided on the outer periphery of the upper end surface of the carrier plate 304. The turntable 401 is installed in the annular limiting protrusion provided on the carrier plate 304. The driving component 402 is specifically a forward and reverse motor. The output end of the driving component 402 is equipped with a toothed card 403. The driving component 402 is sleeved and installed with the turntable 401 through the toothed card 403. A limiting card slot is opened at the bottom of the turntable 401. The turntable 401 is engaged with the toothed card 403 provided at the output end of the driving component 402 through the limiting card slot provided at the bottom. The driving component 402 is engaged with the limiting card slot of the turntable 401 through the toothed card 403, and the starting and stopping positions of the turntable 401 can be controlled more precisely.

[0035] In an embodiment of the present application, the two material placement components 600 are specifically material storage frames. The two material placement components 600 are symmetrically arranged on the frame 200. A plurality of storage slots 601 are provided on the material placement component 600. The plurality of storage slots 601 are arranged in an array. The inner cavities of the plurality of storage slots 601 are all designed as tapered structures 602. By designing the storage slots 601 as tapered structures 602, the placement of workpieces with different shapes and sizes can be adapted.

[0036] The usage process of the loading and unloading mechanism of a hobbing machine provided by the present utility model is as follows: After the hobbing machine table 100 is started, the electric drive component 502 is started. Specifically, the electric drive component 502 is an electric drive rod. The electric drive component 502 drives the moving collar 503 to move up and down, thereby realizing the adjustment of the vertical height of the gripper 505. When the gripper 505 grips the workpiece, after the electric drive component 502 drives the gripper 505 to adjust a certain height, the drive component 402 is started, which can drive the turntable 401 to rotate. Through the rotation of the turntable 401, another set of loading and unloading mechanisms 500 can be rotated to the material placement component 600. Then, the above operations are repeated. After the gripper 505 grips the workpiece, the electric drive component 502 adjusts the height of another set of grippers 505 by a certain amount. At this time, by starting the electric contraction rod 504, the gripper 505 is driven to move. After the gripper 505 moves to the cutting processing area, the height of the gripper 505 is adjusted by the electric drive component 502. Finally, the workpiece is placed in the cutting processing area by controlling the gripper 505, and then the gripper 505 is retracted by the electric contraction rod 504. At this time, by starting the drive component 402, another set of loading and unloading mechanisms 500 with the workpiece gripped is rotated to the processing window of the hobbing machine table 100. Since the two sets of loading and unloading mechanisms 500 are at 90°, when a set of loading and unloading mechanisms 500 with the workpiece gripped rotates to the processing window of the hobbing machine table 100, the other set of loading and unloading mechanisms 500 rotates above the material placement component 600. Then, by repeating the above operations, the clamping and feeding work of the workpiece can be completed.
