Detailed Description

The utility model combines the actual marking and hole making process to invent a novel high-interchangeability accurate marking tool which is suitable for marking and hole making of different products with different structures and different position holes and ensures the high efficiency and accuracy of marking and hole making.

The specific invention content is as follows:

the main body structure is divided into a main ruler and a sliding body.

The main ruler consists of a ruler body, a marking pen, a locker and a limiting piece.

The measuring range of the ruler body is 0-150mm, the measuring precision is 1mm, and the ruler is used for measuring and drawing a line distance and supporting the whole tool framework. The ruler body is provided with a slide rail which can enable the sliding body to slide on the main ruler. The ruler body is provided with a marking pen fixing hole for fixing a marking pen, and the axis of the fixing hole is flush with the outer edge of the sliding body wheel. The ruler body is provided with a locker threaded hole and a limiting part threaded hole which are respectively used for installing the locker and the limiting part.

The taper of the head of the marking pen is not more than 1:1, the total length is not more than 50mm, and the marking pen is used for marking on a part. The marking pen can also adopt a common pencil or an ink pen.

The locker and the limiting piece are stepped pin bodies. The head (small diameter part) is in a thread form and can be matched with a corresponding thread hole on the ruler body. The shoulder (at the larger diameter) is in the form of knurling for increasing the contact surface friction during rotation. The locker is used for fixing the marking pen. The limiting piece is used for limiting the maximum stroke of the sliding body.

The sliding body consists of a sliding block, a sliding ruler, a fixed plate, a wheel, a shaft, a locking nail and a screw.

The sliding block comprises an auxiliary positioning plane, and the plane can be tightly attached to the surface of the part during scribing. The sliding block contains shaft hole and screw hole simultaneously for the installation shaft reaches screws up set screw.

The movable ruler is provided with 10 graduation marks with the interval of 0.9mm and is used for reading one digit after the decimal point of the marking distance. The sliding ruler is provided with a sliding chute which can slide on the sliding rail of the ruler body. The movable ruler is screwed on the sliding block by a screw.

The fixed plate can fix the sliding body on the ruler body and is screwed on the sliding block by screws. The fixing plate is provided with a locking nail threaded hole and a screw threaded hole.

Wheel, axle installation are on the sliding block, when the sliding block slides for the part, can reduce the resistance, improve the smoothness degree.

The locking pin is a stepped pin body. The head (small diameter part) is in a thread form and can be matched with a corresponding thread hole on the ruler body. The shoulder (at the larger diameter) is in the form of knurling for increasing the contact surface friction during rotation. The locking pin is arranged on the fixing plate, and after the scribing size is adjusted, the locking pin is screwed down, so that the relative position of the sliding body and the ruler body can be kept unchanged, and the scribing size accuracy is ensured.

The specific using method comprises the following steps:

firstly, before carrying out the line drawing, operating personnel can choose suitable marking pen according to the actual demand, pack the marking pen into the fixed orifices of the chi body, screw up the locker.

And secondly, adjusting the movable ruler on the sliding body according to the actual marking position size, and then screwing down the locking nail to ensure that the sliding body does not slide relative to the main ruler any more. (in the tool size numerical reading method, the whole millimeter number of the main scale and the scale number of the 0.1 multiplied by the scale number of the moving scale line aligned with the scale line of the main scale before the marking line of the moving scale 0)

And thirdly, using the adjusted marking tool, taking the edge of the sliding body wheel tightly attached to the edge of the part as a reference, attaching the plane of the protruding part of the sliding body wheel shaft tightly to the surface of the part, then properly adjusting the height of the marking pen, enabling the marking pen to contact the surface of the part, and dragging the tool along the edge of the part to mark.

(1) The tool is suitable for hole site arrangement and scribing of parts with different structures and styles, and particularly meets the scribing requirement of high hole site precision requirement.

(2) The tool is flexible, safe, reliable and simple to operate, and research, development and manufacturing costs of the marking tool are saved, so that the manufacturing cost of parts is reduced.

(3) The tool can improve the scribing accuracy and the scribing efficiency.

(4) The utility model provides a solution which is applicable to low-cost and high-efficiency scribing of parts with different structures.
