Description

Technical Field

[0001] The present 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 gear hobbing machine used in existing 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, the teeth on the gears will generate more waste chips during the machining and forming. Although the gear hobbing machine can prevent the waste chips from flying 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, and invisibly increases the work intensity of the staff to clean the machine body. It is impossible to impose certain restrictions on the waste chips during gear machining, and to reduce the waste chips from flying around inside the gear hobbing machine as much as possible.

[0014] A hobbing process for machining a motor shaft includes the following steps:

[0015] Step 1: Positioning and installing the machining shaft: Position and install the machining shaft in the working chamber.

[0016] Step 2: Closing the chamber door: Close the visual chamber door. The movement of the visual chamber door drives the movable bearing plate to move, and further drives the waste chip carrier box to move.

[0017] Step 3: Moving up the limiting movable sleeve: The movement of the movable bearing plate drives the limiting movable sleeve to move upward and sleeved outside the machining shaft and the machining tool.

[0018] Step 4: Machining the gear: Start the hobbing machine body to machine the gear on the machining shaft.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, with the following advantages:

[0020] 1. A movable bearing plate is arranged in the working chamber, and a waste chip carrier box is installed on the movable bearing plate. When machining the gear on the shaft, close the visual chamber door. With the movement of the visual chamber door, under the action of the push-pull linkage rod, it will drive the movable bearing plate to move, and further drive the waste chip carrier box to move, so that the waste chip carrier box can move to the working position to collect the waste chips generated during the machining of the gear on the shaft. After machining, it is convenient to clean the waste chips.

[0021] 2. When the movable bearing plate moves, it will push the bearing cooperation frame to move. With the movement of the bearing cooperation frame, under the action of the movable connection rod, it will push the limiting movable sleeve upward to sleeve it outside the gear to be machined and the machining tool. In this way, it can play a good role in limiting the waste chips, avoiding most of the waste chips from splashing randomly, and enabling them to fall into the waste chip carrier box to achieve collection smoothly.

[0022] 3. Additionally, after the limit movable sleeve moves upward to the working position, as the bearing movable plate continues to move, it will drive the cooperating linkage plate to move. As a result, the upper limit plate on the upper side of the cooperating linkage plate will move towards the upper port of the limit movable sleeve to cover the upper port, thereby reducing the size of the upper port. At the same time, as the cooperating linkage plate moves, it will also drive the U-shaped mating groove sealing plate to move, closing the first U-shaped mating groove part on the upper side of the processing shaft. This can reduce the splashing of waste chips from the upper port and the first U-shaped mating groove. Description of the Drawings

[0044] A hobbing machine processing technology for motor shaft processing includes the following steps:

[0045] Step 1: Positioning and installation of the processing shaft: Position and install the processing shaft in the working chamber 11;

[0046] Step 2: Closing the chamber door: Close the chamber visual door 2. Drive the bearing movable disk 3 to move through the movement of the chamber visual door 2, and then drive the waste chip carrier box 37 to move;

[0047] Step 3: Upward movement of the limit movable sleeve 4: Drive the limit movable sleeve 4 to move upward through the movement of the bearing movable disk 3, and sleeve it on the outside of the processing shaft and the processing tool;

[0048] Step Four: Machining of the gear: Start the hobbing machine body 1 to machine the gear on the processing shaft.

[0049] 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, under the action of the push-pull linkage rod 21, it will push the bearing movable disk 3 to further move into the working chamber 11, thereby driving the waste chip carrier box 37 to move. As the bearing movable disk 3 moves, under the action of the driving and mating inclined plate 35, it will push the mating runner 491 towards the direction of the limiting movable sleeve 4, that is, drive the bearing mating frame 49 to move. As the bearing mating frame 49 moves, under the action of the movable connecting rod 48, it will push the limiting movable sleeve 4 to move upward, so that the limiting movable sleeve 4 is sleeved outside the gear on the shaft and the machining tool until the mating runner 491 contacts the stable limiting plate 34 and the limiting movable sleeve 4 stops moving. At the same time, the bearing mating frame 49 contacts the contact mating block 391, playing a role in limiting it. In this way, as the bearing movable disk 3 moves further, the contact mating block 391 will no longer move. Under the action of the inclined surface driving plate 392, it will push the movable mating connecting rod 38 to move, thereby driving the L-shaped connecting plate 381 towards the direction of the limiting movable sleeve 4. As the L-shaped connecting plate 381 moves, it will drive the mating linkage carrier plate 5 to move. As the mating linkage carrier plate 5 moves, the upper top limiting plate 55 on the mating linkage carrier plate 5 will protrude at the upper port of the limiting movable sleeve 4, achieving a certain blockage of its upper port, which can reduce the overflow of waste chips from the upper port of the limiting movable sleeve 4. In addition, as the mating linkage carrier plate 5 moves towards the direction of the limiting movable sleeve 4, under the action of the connecting and mating driving rod 57, it will push the U-shaped mating groove sealing plate 58 to move, so that the U-shaped mating groove sealing plate 58 closes the part of the first U-shaped mating groove 42 on the upper side of the machining shaft, reducing the opening degree of the first U-shaped mating groove 42, which can also effectively reduce the overflow of waste chips generated during the gear machining process from the first U-shaped mating groove 4, Further, as the bearing movable disk 3 moves, when the waste chip carrier box 37 moves to the working position, the closing baffle 371 on the waste chip carrier box 37 at this time can block the opening on the limiting movable sleeve 4 facing the chamber visual door 2, which can prevent the waste chips from overflowing from this port during the gear machining process. In this way, during the gear machining process, most of the waste chips can be collected into the waste chip carrier box 37 to avoid excessive accumulation in the working chamber 11, making it difficult to clean. When the gear machining is completed, opening the chamber visual door 2 can drive the bearing movable disk 3 to move, thereby driving the waste chip carrier box 37 to reset, facilitating the cleaning of waste chips. At the same time, under the action of the second reset spring 53, it drives the mating linkage carrier plate 5 to reset. In addition, under the action of gravity, it drives the limiting movable sleeve 4 to move downward to reset, and at the same time, under the action of the movable connecting rod 48, it drives the bearing mating frame 49 to reset, facilitating the installation of the machining shaft next time.
