Problems solved by technology

Due to the staged processing of the ellipse, the clamping position is clamped multiple times, so it is often accompanied by the loss of precision, and the final ellipse position is often out of tolerance in size and shape and position and does not meet the design requirements.

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail through the following examples. However, it should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0027] see figure 1 As shown, the manufacturing process of the elliptical cam according to the present invention has the following process steps: blanking→rough turning→heat treatment→finish turning→wire cutting→drilling→ellipse milling→deburring→finished product inspection→cleaning→packing and warehousing .

[0028] (1) Cutting: Use a band saw to decompose the raw material, and check the raw material blank to ensure that the verticality of the end face is ≦1mm;

[0029] (2) Rough turning: Carry out rough turning on the raw material to be processed by a lathe to form an elliptical cam and it...

Abstract

The invention relates to a harmonic reducer, in particular to a manufacturing technology for an elliptical cam. The manufacturing technology comprises the following steps of (1) discharging, (2) roughturning, (3) heat treating, (4) fine turning, (5) linear cutting, (6) drilling, (7) ellipse milling, (8) burr removing, (9) finished product inspecting, (10) cleaning and (11) packaging and warehousing. According to the manufacturing technology for the elliptical cam, the clamping frequency can be effectively decreased, the reference positions are always unified, therefore, the product precisionis improved, the design requirements are fully met, the machining technology process is simple and short, and the machining time is shortened.

Description

technical field [0001] The invention relates to a harmonic reducer, in particular to a manufacturing process of an elliptical cam. Background technique [0002] Harmonic transmission uses the controllable elastic deformation of flexible elements to transmit motion and power, and the controllable elastic deformation of flexible elements is realized through the action of elliptical cams; therefore, elliptical cams play a very important role in harmonic transmission ; At the same time, the higher the precision of the harmonic transmission, the higher the manufacturing precision requirements for the elliptical cam; for the traditional processing method of the elliptical cam, the shape is usually turned out by turning, and the ellipse is used after CNC milling out the ellipse. Grinders perform finishing to meet design standards. Due to the staged processing of the ellipse, the clamping position is clamped multiple times, so it is often accompanied by the loss of precision, and t...
