Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a novel gear processing rapid alignment device. Background Art

[0002] The master and slave gears each have 38 bevel teeth, and the surface roughness of the teeth must be controlled within Ra3.2. A unit consists of two gear assemblies: the master and slave gears. The meshing accuracy between the master and slave gears will affect the unit's operating performance. To ensure this meshing accuracy, gear surface machining is paramount. However, there are several machining difficulties:

[0003] 1. The efficiency of parts clamping is low. The processing of the master and slave wheels belongs to batch parts. Each time the parts are processed and aligned, they need to be placed in the middle of the workbench. The existing technology is to use 4 flat irons to install the workpiece. There is no positioning reference, and the re-processing wastes alignment time. Each clamping and alignment takes at least 2 hours.

[0004] 2. Moreover, parts need to be moved when finding the timing. Standard shims may be displaced, and there is a risk of parts falling.

[0005] 3. When the original clamp is used, placing the gear to be processed directly on the four adjustment pads is very likely to cause vibration, loosen the tool screws, and often cause digging, resulting in product quality problems and even causing the gear to be processed to be completely scrapped. Utility Model Content

[0006] The purpose of this utility model is to solve the problems of low clamping efficiency and long clamping time during the gear processing process, solve the problems of no reference in the previous clamping, and improve the stability and efficiency of clamping. The processed gear is a component of a double-sided rubber rubbing calendering line.

[0007] The technical solution adopted by the present invention to achieve the above-mentioned purpose is as follows: a novel gear machining rapid alignment device, comprising a machine tool alignment platform 1, a support shim 2, an alignment device body 3, a pressure plate 4, and a reducing device 5; the alignment device body 3 is located on the machine tool alignment platform 1; the shape and size of the alignment device body 3 correspond to the inner hole of the gear to be machined;

[0008] The support shim 2 is located between the pressure plate of the alignment device body 3 on the machine tool alignment platform 1 and the machine tool alignment platform 1, and is used to support the height difference between the two;

[0009] The reducing device 5 is installed around the main body 3 of the aligning device; the pressing plate 4 is located at the top of the main body 3 of the aligning device and is used to press the gear to be processed.

[0010] The outer diameter of the alignment device body 3 is 0.2 mm smaller than the inner diameter of the gear to be machined.

[0011] The machine tool alignment platform 1 and the alignment device body 3 are both pre-aligned.

[0012] The reducing device 5 is four reducing positioning keys installed on the main body 3 of the alignment device. Four positioning key grooves are machined on the circumference of the outer circle of the upper end of the main body 3 of the alignment device. Two pins are machined on the bottom surface of the positioning key grooves. The reducing positioning keys are fastened to the main body 3 of the alignment device through the pins. The outer circle of the reducing positioning keys is machined to the required reducing size by CNC vertical lathe.

[0013] The beneficial effects of this utility model include rationally utilizing resources and effectively utilizing tools, addressing issues such as low clamping efficiency and long clamping times during batch gear processing. It also addresses the previous issue of no reference for clamping, improving clamping stability and efficiency. Energy conservation and emission reduction are achieved during processing, achieving green production and environmentally friendly manufacturing. This significantly enhances the company's competitiveness and promotes the development of local industries. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The novel gear machining rapid alignment device of the utility model mainly consists of an alignment device body 3 and four diameter reducing devices 5.

[0019] The alignment device body 3 may be a disc-type mold.

[0020] Make a Figure 1 The alignment device body 3, shown in the figure, is sized to the inner bore of the gear being machined, 0.2 mm smaller than the inner bore. Adjust it to the appropriate position and secure it to the machine tool alignment platform 1. Four reducers 5 are used to adjust the settings for other gear types to be machined, enabling a single device for multiple uses. After inserting the gear into the device, a pressure plate 4 is used to hold it in place. This completes the gear alignment.

[0021] Further, make a alignment device body 3 (see Figure 1 ), adjust it to the appropriate position and fix it on the machine tool alignment platform (see Figure 1 ) and complete the alignment. Reducer 5 (see Figure 1 ) is used to set the inner hole size of other gear models, which can realize multiple uses of one device. After the gear is embedded in the device, the pressure plate is used to press the gear to be processed 4 (see Figure 1 ). The gear alignment is completed. After processing the next gear, the pressure plate is removed and the gear to be replaced is replaced. There is no need to align the alignment device body and the alignment platform, which greatly reduces the alignment time and improves the alignment stability.

[0022] The reducing device 5 is four reducing positioning keys installed on the main body 3 of the alignment device. Four positioning key grooves are machined on the circumference of the outer circle of the upper end of the main body 3 of the alignment device. Two pins are machined on the bottom surface of the positioning key grooves. The reducing positioning keys are fastened to the main body 3 of the alignment device through the pins, and the outer circle of the reducing positioning keys is machined to the required reducing size by CNC vertical lathe.
