Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing, and in particular to a processing device for fan-shaped distributed elongated holes and a processing method thereof. Background Art

[0002] In the fields of mechanical manufacturing and machining, it is often necessary to produce elongated holes with high precision, large depth, and small diameter. Existing elongated hole processing typically utilizes various machine tools and tools, performing multiple machining operations on the workpiece. However, after multiple machining operations, existing methods struggle to maintain the positional accuracy of the end faces of the elongated holes. Furthermore, existing technologies primarily process single holes or parallel rows or multiple rows of holes, failing to achieve fan-shaped distribution of fine holes.

[0003] Furthermore, with the advancement of technology, the heat dissipation requirements of various electronic and mechanical equipment are becoming increasingly stringent. This proposal proposes a fan-shaped distributed long and thin hole processing device and processing method. This method can realize the processing of fan-shaped long and thin holes, and the processed products can help optimize the heat exchanger structure. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide fan-shaped distributed elongated hole processing equipment and a processing method thereof, which can process fan-shaped distributed elongated holes on thin plates, and the processed plate with fan-shaped distributed elongated holes can be used as a heat exchange structure. As a heat exchange structure, its fan-shaped structural characteristics are more suitable for use in heat exchange devices whose external medium is fluid, and are more suitable for use in special-shaped structural equipment with fan-shaped or fluid-shaped installation space.

[0005] The object of the present invention is achieved through the following technical solutions:

[0006] First, on the one hand, the present invention provides a fan-shaped distributed elongated hole processing device, comprising: a tooling device, which is movable along a first direction;

[0007] An angle measuring head is mounted on the fixture so as to be quantitatively rotatable, and its rotation axis is in a second direction, which is perpendicular to the first direction;

[0008] A processing device is provided with a processing head, wherein a processing direction of the processing head is perpendicular to the first direction and the second direction respectively;

[0009] The part to be processed is mounted on the angle measuring head, and the direction of the holes to be processed on the part to be processed is perpendicular to the rotation axis of the angle measuring head; when the angle measuring head is rotated, the multiple holes to be processed on the part to be processed and the processing direction of the processing head are always located in the same plane.

[0010] Heat exchange is the transfer of heat between two objects, or parts of the same object, due to a temperature difference. Heat exchange methods are generally divided into two types: air cooling and liquid cooling. With the advancement of technology, the heat dissipation requirements of various electronic and mechanical devices are becoming increasingly stringent. For example, the liquid cooling devices in submarines require high stability in their installation and should not be too large due to space constraints.

[0011] In a preferred embodiment of the present invention, a U-shaped clamp for fixing the part to be processed is provided at one end of the angle measuring head; the bottom surface of the U-shaped clamp is perpendicular to the rotation axis of the angle measuring head, so that the part to be processed can be vertically mounted at one end of the angle measuring head.

[0012] In a preferred embodiment of the present scheme, a threaded hole is provided on the side of the U-shaped clamp, and the part to be processed can be clamped into the U-shaped clamp and fixed by screws; the side width of the U-shaped clamp is smaller than the side width of the part to be processed. After the installation is completed, the side of the U-shaped clamp does not reach the projection position of the processing hole on the side.

[0013] In a preferred embodiment of this solution, the processing device is a punching machine.

[0014] In a preferred embodiment of this solution, the angle measuring head is a universal dividing head.

[0015] In a preferred embodiment of this solution, the fan-shaped distributed elongated hole processing equipment is also equipped with a cutting machine for fine-machining holes.

[0016] In a preferred embodiment of the present solution, the fan-shaped distributed elongated hole processing equipment further includes a guide rail; the length direction of the guide rail is the first direction, and the tooling is slidably mounted on the guide rail.

[0017] In a preferred embodiment of this solution, the fan-shaped distributed elongated hole processing equipment is further equipped with a wire cutting machine; the cutting direction of the wire cutting machine is always in the same plane as the multiple holes to be processed on the workpiece to be processed. The holes are finely processed by the wire cutting machine.

[0018] On the other hand, the present invention also proposes a method for machining sector-shaped distributed pores using the above-mentioned machining device, comprising the following steps:

[0019] S1: Fixing the angle measuring head on a tooling, wherein the tooling can drive the angle measuring head to move along a first direction;

[0020] The workpiece to be processed is fixed on an angle measuring head, which is mounted on a tooling device so as to be rotatable in a quantitative manner, and the rotation axis of the angle measuring head is in a second direction. The angle measuring head can drive the workpiece to be processed to rotate in a first plane, wherein the first plane is perpendicular to the second direction and the first direction is parallel to the first plane;

[0021] Align the machining head of the machining device with the workpiece to be machined so that the multiple holes to be machined and the machining direction of the machining head are always located in the same plane;

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

[0023] S3: Turn on 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;

[0025] S5: Adjust the machining head to align with the center of the next hole to be machined, and then start the machining head again to machine the elongated hole;

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

[0027] In a preferred embodiment of this solution, the processing device is a punching machine. In steps S3 and S5, the specific operation of aligning the processing head with the center of the hole to be processed includes steps A and B:

[0028] A. Zeroing the 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 contacts the leftmost or rightmost end of the part to be processed. At this time, fix the movable tooling and reset the punching machine so that the current position of the processing head is zero.

[0030] B. Align the machining head with 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.

[0032] In a preferred embodiment of this solution, the method for processing sector-shaped distributed pores further includes steps S7 to S11:

[0033] S7. After all holes have been processed by the processing device, the punching machine is replaced with a wire cutting machine. The busbar of the wire cutting machine is set vertically, and the rotating angle measuring head is used to make the first hole to be processed on the part to be processed vertical.

[0034] S8. Adjust the wire cutting machine so that the busbar is aligned with and passes through the center of the hole to be processed, and start the wire cutting machine to process the first hole;

[0035] S9, after machining the first hole, rotate the angle of the angle measuring head again to make the next hole to be machined vertical;

[0036] S10, adjust the wire cutting machine again, align the busbar with the center of the next hole to be processed, and start the wire cutting machine to start processing the second hole;

[0037] S11. Repeat the above operations S9 and S10 until all holes are finished.

[0038] In a preferred embodiment of this solution, the specific operation of aligning the busbar and passing through the center of the hole to be processed in steps S8 and S10 includes steps a and b:

[0039] a. Busbar zeroing

[0040] After adjusting the verticality of the hole to be processed, slide the tooling so that the busbar contacts the leftmost or rightmost end of the part to be processed. At this time, fix the movable tooling and clear the wire cutting machine so that the busbar position at this time is the zero point;

[0041] b. The busbar passes through the hole to be processed

[0042] Calculate the horizontal distance from the hole to be processed to the leftmost or rightmost end of the part to be processed, then remove the busbar, and run the wire cutting machine empty according to the distance to align the busbar with the center of the hole to be processed, and then install the busbar.

[0043] In a preferred embodiment of this solution, in steps S2, S4, and steps S7, S9, the specific operation method of rotating the angle measuring head to make the hole to be processed vertical is as follows:

[0044] According to the angle requirements on the drawing, the rightmost hole is the first hole. The angle between the first hole and the side of the workpiece to be machined is β1°. The angle between the second hole and the first hole is β2°. The angle between the third hole and the second hole is β3°. And so on.

[0045] First, place the part to be machined in a vertical direction, then rotate the angle measuring head β1° to the left to make the first hole to be machined vertical;

[0046] When the first hole is machined, the angle measuring head is rotated β2° to the right to make the second hole to be machined vertical;

[0047] When the second hole is machined, the angle measuring head is rotated β3° to the right to make the third hole to be machined vertical. Similarly, each elongated hole can be adjusted vertically one by one.

[0048] In a preferred embodiment of the present invention, the method for processing sector-shaped distributed pores further includes step S12: removing the processed parts and cleaning them.

[0049] In a preferred embodiment of the present solution, the method for machining sector-shaped distributed pores further comprises step S13: cutting the part to be machined according to a required contour after cleaning.

[0050] In a preferred embodiment of the present scheme, if the length of the elongated hole to be processed exceeds the maximum processable length of the punching machine and is less than 1 / 2 of the length of the elongated hole, the part to be processed can be removed after step S6, and the part can be rotated 180° and clamped on a U-shaped fixture, and then processed again according to steps S1 to S6. Two punching operations in opposite directions can penetrate the hole to be processed.

[0051] The beneficial effects of the present invention are:

[0052] (1) In this solution, the processing head vertical device of the processing device vertically rotates the angle measuring head to make the first hole to be processed on the part to be processed vertical, then quantitatively moves the processing head so that the processing head is aligned with the center of the first hole to be processed, starts the processing device, and moves the processing head downward to process the first hole, then again rotates the angle measuring head to make the second hole to be processed on the part to be processed vertical, moves the processing head so that the processing head is aligned with the center of the second hole to be processed, and then processes the next hole. Repeating the above operations multiple times can make multiple holes present a fan-shaped distribution on the thin plate, so that this solution can process fan-shaped distributed slender holes on the thin plate;

[0053] (2) In the specific operation steps, this solution accurately adjusts the processing hole through the quantitative rotation of the universal dividing head to make the hole to be processed vertical; this solution also accurately locates the zero point position before each processing operation through zeroing of the processing head and busbar, and then performs horizontal quantitative adjustment through the punching machine or wire cutting machine. The adjustment accuracy is high and the horizontal position is accurate. Therefore, this solution method can accurately adjust the parts to be processed, accurately locate the hole position, have high processing accuracy, and have a simple equipment structure;

[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 a conical or fluid-shaped space, so this solution 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
