Guiding rule for quick and precise locating

Abstract

The invention discloses a guiding rule for quick and precise locating and belongs to a guiding rule mechanism on processing devices. The guiding rule for quick and precise locating comprises a guiding rule body, a sliding table, a sliding rail and a screw rod and is characterized in that a half-nut capable of sliding up and down only is arranged in the middle of the sliding table; a scale hand wheel is arranged at one end of the screw rod; the threads of the half-nut can be engaged / disengaged with the threads of the thread rod by sliding the half-nut up / down; the half-nut and the thread rod can be disengaged, so that the guiding rule body can quickly move on the sliding rail; after the threads of the half-nut are engaged with the threads of the thread rod, the scale hand wheel is used for slight regulation, thereby resulting in extremely precise locating of the guiding rule body, remarkably improving the working efficiency and processing quality in practical work, and relaxing and pleasing operational staff in the use process.

Description

technical field [0001] The invention relates to a ruler leaning mechanism in a processing machine, which can be widely used in desktop cutting machines, band saw machines, woodworking trimming machines and other mechanical equipment. Background technique [0002] In the processing machinery of modern wood and similar materials, the ruler is a widely used processing size control component, which can effectively control the processing size and improve work efficiency. In the actual operation process, due to the different processing sizes, it is necessary to frequently adjust the ruler. However, although the existing rulers on the market have various structures and varieties, they are generally not flexible enough to operate and the size positioning is not accurate enough. [0003] The invention patent with the patent number 201420036268.6 discloses a fine-tuning structure of a woodworking band saw machine with a ruler.

Problems solved by technology

In the actual operation process, due to the difference in processing size, it is necessary to adjust the ruler frequently. However, although the existing rulers on the market have various structures and varieties, the general operation is not flexible enough, and the size positioning is not accurate enough.

[0003] The invention patent with the patent number 201420036268.6 discloses a fine-tuning structure of a woodworking band saw machine with a ruler. The fine-tuning of this structure is similar to the method of a vernier caliper. When the ruler moves to an approximate position, fix the fine-tuning slide plate and then rotate the fine-tuning lever. In this scheme , the shortcomings are as follows: the size value is not accurate, and the scale is generally only accurate to about 1mm. Every time the size is adjusted, the fine-tuning plate needs to be fixed first, and then fine-tuned.

[0004] The invention patent with the patent number of 201220212178.9 discloses a sliding table saw control fine-tuning type large scale, which uses a screw drive. If the scale is used and the scale is added to the hand wheel, the accuracy of the size can be greatly increased. In the processing environment, the size needs to be adjusted frequently. If the size movement value is large, the handwheel should be turned several times. The disadvantage is that the size adjustment speed is slow.

[0005] The document with the patent application number 201210438020.8 discloses the backing of the digital display on the mini table saw. Zero proofreading, and this structure is not suitable for large size of the ruler
