Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to processing equipment for fan-shaped distributed elongated holes. Background Art

[0002] In the field of mechanical manufacturing and machining, it is often necessary to process some elongated holes with high precision, large depth and small diameter. Existing elongated hole processing usually uses different types of machine tools and tools to process the workpiece multiple times. However, after multiple processing, the position accuracy of the end faces of the elongated holes at both ends of the existing methods is difficult to guarantee, and more importantly, the existing technology mostly processes a single hole or a row of holes or multiple rows of holes parallel to each other, and cannot realize the processing of fan-shaped distributed fine holes.

[0003] In addition, with the development of science and technology, the heat dissipation requirements of various electronic equipment and mechanical equipment are getting higher and higher. This scheme now proposes a fan-shaped distributed long and thin hole processing equipment, which can realize the fan-shaped distributed long and thin hole processing, and the processed product can be beneficial to optimize the heat exchanger structure.

[0009] The processing device is provided with a processing head for fine hole processing. When the angle measuring head is rotated, a plurality of holes to be processed on the processed part and the processing direction of the processing head are always located in the same plane.

[0010] Heat exchange is the process of heat transfer between two objects or parts of the same object caused by temperature difference; the heat exchange methods are usually divided into two methods: air cooling and liquid cooling. With the development of science and technology, the heat dissipation requirements of various electronic and mechanical equipment are getting higher and higher; for example, the liquid cooling device in a submarine has high requirements on the stability of the equipment installation, and the equipment volume should not be too large due to space limitations.

[0011] In a preferred embodiment of the present solution, a fixture for fixing the part to be processed is provided at one end of the angle measuring head, and the part to be processed is detachably mounted on the angle measuring head through the fixture.

[0020] On the other hand, the present invention also proposes a method for machining sector-shaped distributed fine holes using the above-mentioned machining device, comprising the following steps:

[0021] S1. Vertically install the processed part at one end of the angle measuring head;

[0022] S2. According to the drawing requirements, the rotating angle measuring head makes the first hole to be processed on the part to be processed vertical;

[0023] S3, start the processing equipment, align the processing head with the center of the hole to be processed, and then start the processing head to process the first hole;

[0024] S4. After processing, rotate the angle of the angle measuring head again to make the next hole to be processed vertical;

[0026] S6. Repeat the above operations S4 and S5 until all holes are processed.

[0027] In a preferred embodiment of the present solution, in the steps S3 and S5, the specific operation of aligning the machining head with the center of the hole to be machined includes steps A and B:

[0028] A. Zeroing of machining head

[0029] After adjusting the verticality of the hole to be processed, move the processing head downward and slide the tooling so that the processing head head contacts the leftmost or rightmost position of the part to be processed. At this time, fix the movable tooling and clear the punching machine so that the position of the processing head head at this time is the zero point;

[0030] B. Align the machining head to the hole to be machined

[0031] Move the machining head upwards and calculate the horizontal distance from the hole to be machined to the leftmost or rightmost end of the part to be machined. Then, move the machining head horizontally according to the distance to align the machining head with the center of the hole to be machined.

Two punching processes in opposite directions can penetrate the hole to be processed.

[0051] The beneficial effects of the utility model are:

[0052] (1) In this solution, the processing head vertical device of the processing device makes the first hole to be processed on the part to be processed vertical by rotating the angle measuring head, then moves the processing head quantitatively to align the processing head with the center of the first hole to be processed, starts the processing device, moves the processing head downward to process the first hole, then rotates the angle measuring head again to make the second hole to be processed on the part to be processed vertical, moves the processing head to align the processing head with the center of the second hole to be processed again, and then processes the next hole.

[0054] (3) The thin plate with fan-shaped distributed elongated holes is cut into a fan-shaped structure, and then the structure is used as the heat exchange structure of the heat exchange device. Its fan-shaped shape can be suitable for installation of special-shaped equipment with conical or fluid-shaped space, so this scheme is more suitable for streamlined submarine heat exchange; the fan-shaped thin plate can also directly contact the flowing water structure for heat exchange, which is beneficial to reduce fluid resistance. Compared with the heat exchange tube structure of the tubular heat exchanger, it is more stable. BRIEF DESCRIPTION OF THE DRAWINGS
