Problems solved by technology

At present, due to the limitation of mechanical processing methods, the precision tolerance of domestic disc mills and cone mills is generally not higher than 0.05mm, while the precision tolerance of imported machines is generally not higher than 0.01mm, but the price of imported machines is higher than that of domestic machines. Machine ten to dozens of times, can not be widely used in our country

Embodiment Construction

[0016] Method 1:

[0017] A finishing assembly method for a high-precision pulp refiner, firstly assembling a base (1), a transmission motor (2), a transmission spindle (3), and a stator support (4) assembled together with a refining chamber in sequence, The feed device (6) that can realize the axial displacement of the transmission spindle (3) or the stator support body (4), is characterized in that when the machine head (5) is installed,

[0018] A. First install the fixed grinding block (9) between the teeth of the rotor (7) installed at one end of the drive shaft (3), then install the stator (8), and turn the machine on to make the grinding block (9) place the stator (8) The tooth tip is ground to the specified dimensional accuracy, stop the machine and remove the grinding block (9) of the rotor (7);

[0019] B. Install the fixed grinding block (9) between the teeth of the stator (8) and install it, start the machine to make the grinding block (9) grind the tooth top of t...

Abstract

The fine assembling method of high-accuracy pulp-grinding machine is mainly characterized by that when the machine head is mounted, between teeth of stator and rotor the fixed grinding blocks are respectively mounted so as to grind rotor and stator. The pulp-grinding machine assembled by using said fine assembling method can effectively ensure the matching accuracy of rotor and stator and can ensure pulp-grinding quality.

Description

technical field [0001] The invention relates to a production method for refining, processing and assembling, in particular to a finishing and assembling method for a high-precision refining machine. Background technique [0002] All kinds of continuous beating equipment such as disc mills, cone mills, etc. are all acting on a single fiber, that is, cutting, swelling and splitting a single fiber, and the diameter of a single fiber is generally 0.01 Between -0.05mm, so when the precision difference between the rotor stators of the beating equipment (the degree of misalignment and non-parallelism between the tooth surfaces of the rotor stators) exceeds the diameter of a single fiber, its beating efficiency and beating evenness It will be greatly reduced, thereby increasing the power consumption of beating and reducing the quality of pulp. At present, due to the limitation of mechanical processing methods, the precision tolerance of domestic disc mil...
