Description

Technical Field

[0001] This invention relates to the field of positioning tooling technology, specifically to a positioning tooling for horizontal machining of position holes on irregularly shaped parts. Background Technology

[0002] In the field of workpiece machining, drilling is one of the most common machining operations. As we all know, before drilling, it is necessary to accurately locate the hole position and diameter on the workpiece. However, when machining the position hole on irregular workpieces by horizontal machining, it is often necessary to calculate manually and measure accurately by measuring equipment. Finally, a mark is made on the workpiece to improve the accuracy of drilling and hole position verification.

[0003] However, in the existing technology, when mass-producing irregular workpieces, the positioning before drilling and the hole position verification after drilling become quite cumbersome. Therefore, a quick positioning fixture for the position hole of the horizontal machining of such irregular workpieces has emerged. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a positioning fixture for horizontal machining of irregular parts with position holes. It can limit the downward movement, side movement, upward elastic pressing, and pin movement of irregular workpieces, thereby enabling rapid and accurate positioning of irregular workpieces on the positioning fixture, improving the efficiency and accuracy of horizontal machining.

[0005] A positioning fixture for machining position holes on a non-standard part includes a base plate, a T-shaped column, and a π-shaped plate, wherein the T-shaped column and the π-shaped plate are fixedly and alternately disposed on the top surface of the base plate; the top of the π-shaped plate is threadedly connected to a limiting block for a downward limiting non-standard part; a pin is slidably inserted into the middle of the T-shaped column along the horizontal X direction, and a limiting pressure block for an upward limiting non-standard part is elastically pressed into the top of the T-shaped column; and a limiting clamping block for a lateral limiting non-standard part is threadedly connected to the side wall of the T-shaped column along the horizontal Y direction; one end of the pin is slidably inserted into the π-shaped plate.

[0006] Preferably, both the limiting top block and the limiting clamping block have screws fixedly installed through their middle parts; the screw of the limiting top block is threadedly connected to the top surface of the π-shaped vertical plate located above the through connection position between the pin and the π-shaped vertical plate; the screw of the limiting clamping block is threadedly connected to the side wall of the T-shaped column.

[0007] Preferably, a guide rod is fixedly installed at the bottom of the limiting block; the guide rod is slidably inserted into the top surface of the T-shaped column, and a top support spring is fitted on the guide rod located inside the T-shaped column; the top end of the top support spring elastically supports the inner wall of the T-shaped column, and the bottom end of the top support spring is fixedly connected to the bottom end of the guide rod.

[0008] The advantages and technical effects of this invention are:

[0009] This invention discloses a positioning fixture for horizontal machining of a non-standard part. The fixture positions the horizontal hole at the bottom of the non-standard part by rotating a pin. A limiting clamping block clamps the non-standard part laterally on a T-shaped column. Simultaneously, a limiting top block moves downward to limit and support the non-standard part, and a limiting pressure block elastically moves upward to limit and press against the non-standard part, achieving rapid and precise positioning of the non-standard part. Furthermore, one end of the non-standard part is pressed against by the limiting pressure block on the T-shaped column, while the other end is supported by a limiting top block on a π-shaped plate. The T-shaped column and the π-shaped plate are spaced apart, thus suspending the central machining area of ​​the non-standard part, facilitating horizontal machining of the central portion.
