Description

Technical Field

[0001] The invention relates to the technical field of gear hobbing machines, in particular to a gear hobbing machine for machining motor shafts and a machining process thereof. Background Art

[0002] Gear hobbing machine is the most widely used machine tool in machining. It can process gears on shafts with high work efficiency and excellent machining quality. Although the existing gear hobbing machine used for shaft machining has a high degree of intelligence, it is not only easy to operate but also can reduce the work intensity of the staff to a great extent. However, it still has certain shortcomings. That is, during the machining process of the gears on the shaft, more waste chips will be generated when the teeth on the gears are processed and formed. Although the gear hobbing machine can prevent the waste chips from splashing everywhere, the waste chips generated by machining the gears will accumulate inside the gear hobbing machine, which makes it very troublesome to clean the waste chips inside the gear hobbing machine, which invisibly increases the work intensity of the staff to clean the machine body.

[0013] A gear hobbing process for motor shaft machining comprises the following steps: Step 1: Positioning and installing the processing axis: Position and install the processing axis in the working chamber; Step 2: closing the chamber door: closing the chamber visual door, and moving the chamber visual door drives the carrying movable plate to move, thereby driving the waste chip carrying box to move; Step 3: Move the limit movable sleeve upward: the limit movable sleeve is driven to move upward by the movement of the bearing movable plate, and is sleeved on the outer side of the processing shaft and the processing tool; Step 4: Gear processing: Start the gear hobbing machine to process the gear on the processing shaft.

[0014] Compared with the prior art, the invention has the following advantages: 1. A carrying movable plate is provided in the working chamber, and a waste chip carrying box is installed on the carrying movable plate. When processing the gears on the shaft, the visible door of the chamber is closed. As the visible door of the chamber moves, the carrying movable plate is driven to move under the action of the push-pull linkage rod, and then the waste chip carrying box is driven to move. When the waste chip carrying box moves to the working point, the waste chips generated during the processing of the gears on the shaft can be collected. After the processing is completed, the waste chips can be cleaned up conveniently.

[0015] 2. As the carrying movable plate moves, it will push the carrying matching frame to move. As the carrying matching frame moves, the movable limiting sleeve will be pushed upward under the action of the movable connecting rod so that it can be sleeved on the outer side of the gear to be processed and the processing tool. This can play a good limiting role on the waste chips, avoiding most of the waste chips from splashing randomly, so that they can fall into the waste chip carrier box and be collected smoothly.

[0016] 3. In addition, after the limiting movable sleeve moves up to the working position, as the supporting movable plate continues to move, it will drive the matching linkage carrier plate to move, and then the upper top limiting plate on the upper side of the matching linkage carrier plate will move toward the upper port of the limiting movable sleeve to cover the upper port, thereby reducing the upper port. At the same time, as the matching linkage carrier plate moves, it will also drive the U-shaped matching groove sealing plate to move, so that it will close the first U-shaped matching groove part on the upper side of the processing axis, thereby reducing the waste chips splashing out from the upper port and the first U-shaped matching groove.

[0036] A connecting and fitting cavity 54 is provided at the lower end of the matching linkage carrier 5, in which an L-shaped connecting plate 381 is inserted, a top limit plate 55 is fixedly provided at the upper end of the matching linkage carrier 5, and a first protruding connecting frame 56 is also symmetrically fixedly provided on the upper side of the matching linkage carrier 5, a connecting and fitting driving rod 57 is hinged on the first protruding connecting frame 56, and a U-shaped matching groove sealing plate 58 is hinged on the other end of the connecting and fitting driving rod 57, the U-shaped matching groove sealing plate 58 is inserted in the movable plug-in channel 43, and a second protruding connecting frame 59 is fixedly provided on the U-shaped matching groove sealing plate 58, and the second protruding connecting frame 59 is hinged to the connecting and fitting driving rod 57, in addition, the upper end surface of the U-shaped matching groove sealing plate 58 contacts the lower end surface of the top limit plate 55, and the lower end surface of the U-shaped matching groove sealing plate 58 contacts the inner bottom surface of the movable plug-in channel 43.

[0037] A gear hobbing process for motor shaft machining comprises the following steps: Step 1: Positioning and installing the processing axis: Positioning and installing the processing axis in the working chamber 11; Step 2: closing the chamber door: closing the chamber visual door 2, and the movement of the chamber visual door 2 drives the carrying movable plate 3 to move, thereby driving the waste chip carrying box 37 to move; Step 3: Move the limit movable sleeve 4 upward: The limit movable sleeve 4 is driven to move upward by the movement of the bearing movable plate 3, and is sleeved on the outer side of the processing shaft and the processing tool; Step 4: Gear processing: Start the gear hobbing machine body 1 to process the gear on the processing shaft.

[0038] When machining the gear on the shaft, the machining shaft is positioned and installed in the working chamber 11, and then the chamber visual door 2 is closed. As the chamber visual door 2 moves, the supporting movable disk 3 is pushed further into the working chamber 11 under the action of the push-pull linkage rod 21, thereby driving the waste chip carrier 37 to move. As the supporting movable disk 3 moves, the driving matching inclined plate 35 pushes the matching wheel 491 to move in the direction of the limiting movable sleeve 4, that is, drives the supporting matching frame 49 to move. As the supporting matching frame 49 moves, the limiting movable sleeve 4 is pushed upward under the action of the movable connecting rod 48, thereby making the limiting movable sleeve 4 sleeved on the outer side of the gear on the shaft and the machining tool until the matching wheel 49 is engaged. 1 contacts with the stable limiting plate 34, the limiting movable sleeve 4 no longer moves, and at the same time, the bearing matching frame 49 contacts with the contact matching block 391, which plays a limiting role on it. In this way, as the bearing movable disk 3 moves further, the contact matching block 391 will no longer move. In this way, under the action of the inclined driving plate 392, the movable matching connecting rod 38 will be pushed to move, thereby driving the L-shaped connecting plate 381 to move in the direction of the limiting movable sleeve 4. As the L-shaped connecting plate 381 moves, it will drive the matching linkage carrier plate 5 to move. As the matching linkage carrier plate 5 moves, the upper limiting plate 55 on the matching linkage carrier plate 5 will protrude from the upper port of the limiting movable sleeve 4, and its upper port will be blocked to a certain extent, so that In order to reduce the overflow of waste chips from the upper port of the limiting movable sleeve 4, in addition, as the cooperating linkage carrier plate 5 moves toward the limiting movable sleeve 4, the U-shaped matching groove sealing plate 58 will be pushed to move under the action of the connecting and matching driving rod 57, so that the U-shaped matching groove sealing plate 58 closes the part of the first U-shaped matching groove 42 on the upper side of the processing axis, reducing the opening and closing degree of the first U-shaped matching groove 42. This can also effectively reduce the overflow of waste chips generated by the gear during the processing from the first U-shaped matching groove 42. Furthermore, as the supporting movable disk 3 moves, when the waste chip carrier box 37 moves to the working point, the closed baffle 371 on the waste chip carrier box 37 can open the opening of the limiting movable sleeve 4 towards the chamber visual door 2. It is blocked to prevent waste chips from overflowing from this port during gear processing. In this way, most of the waste chips can be collected in the waste chip carrier box 37 during gear processing to prevent excessive accumulation in the working chamber 11, which is difficult to clean. When the gear processing is completed, opening the chamber visual door 2 can drive the supporting movable plate 3 to move, and then drive the waste chip carrier box 37 to reset, which is convenient for cleaning the waste chips. At the same time, under the action of the second reset spring 53, it drives the coordinated linkage carrier plate 5 to reset. In addition, under the action of gravity, the limiting movable sleeve 4 is driven to move downward for reset. At the same time, under the action of the movable connecting rod 48, the supporting matching frame 49 is driven to reset, which is convenient for the next installation of the processing shaft.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
