Automatic chain grinding machine and chain grinding method

Abstract

The invention discloses an automatic chain grinding machine and a chain grinding method thereof. The automatic chain grinding machine includes a box body and a saw chain installation device fixed on the box body. It is characterized in that the box body is also provided with a tooth pushing mechanism for pushing the saw chain teeth, and a clamping mechanism for realizing the clamping of the saw chain. mechanism, a grinding indexing mechanism for grinding saw chain teeth, and an electrical control device for controlling the automatic grinding process. connect. The present invention also provides a chain grinding method for the above-mentioned automatic chain grinding machine, including the steps of pushing teeth and tooth shape detection, clamping the saw chain, adjusting the grinding indexing mechanism to align the grinding wheel with the saw chain teeth that need to be ground, and the saw chain The tooth grinding step, the saw chain loosening step, and the pushing tooth mechanism move to the next pushing tooth position step. The invention has the characteristics of reasonable design, simple structure, stable performance, high grinding precision, simple operation and debugging, and the like.

Description

technical field [0001] The invention relates to an automatic chain grinding machine and a chain grinding method thereof, which are used for grinding teeth on a saw chain and belong to grinding tools. Background technique [0002] The saw chain is the cutting part of the chain saw. The cutting edge is divided into left and right blades and exists in the same saw chain at the same time. The saw chain is a tool used to cut objects. After long-term use, it will become dull, resulting in reduced cutting resistance. It is even impossible to cut, so the saw chain teeth need to be ground so that they can continue to meet the needs of the work. In the prior art, manual grinding or semi-automatic grinding is usually used, both of which have problems such as low grinding precision, low work efficiency, and high labor intensity. [0003] There are also some automatic chain grinding machines on the market now, but they all have the following disadvantages: [0004] 1. There are too man...

AI Technical Summary

Problems solved by technology

[0004] 1. There are too many components in the transmission process of the chain-feeding and pushing-tooth device, and there is no positioning accuracy. Many components (especially belt transmission) have assembly errors and plastic deformations. The positioning accuracy is very poor during the feeding process, which cannot meet the processing requirements.

[0005] 2. The design of the tooth pushing device is unreasonable, and the length of each tooth cannot be guaranteed to be consistent, and the inconsistency of the tooth length will lead to unbalanced loads on the left and right during the actual cutting process of the chain saw, seriously affecting the cutting effect

[0006] 3. The design of the grinding device is unreasonable, and the rigidity and positioning accuracy are insufficient. When encountering grinding resistance and motion friction resistance, it will cause random deformation of the mechanism, and cannot provide stable and reliable cutting position accuracy.

[0007] 4. The center of rotation designed in the indexing device is unreasonable, which will lead to errors in grinding angle and grinding depth after assembly errors and grinding wheel wear

[0008] 5. The torque of each mechanism is kept small after moving and positioning. When encountering external resistance and grinding resistance, it is easy to cause great changes in the existing position

[0009] 6. It is inconvenient to use and debug the equipment, it has high requirements for the operator, and the adjustment procedure is cumbersome and complicated

[0010] 7. There is no device for automatic detection of left and right knife shapes, which cannot meet the grinding requirements of saw chains with irregular arrangement of left and right knife shapes
