Description

Technical Field

[0001] The invention relates to the technical field of copper-zinc alloy back plate production, and in particular to a copper-zinc alloy back plate continuous machining device and method. Background Art

[0002] Copper-zinc alloy backplanes, also known as brass backplanes, are widely used in electronic equipment, building decoration, chemical equipment, medical equipment, precision instruments and other fields. They are most widely used in electronic equipment, such as computers, servers, communication equipment and other electronic equipment backplanes. They are mainly used to provide structural support and protection. The copper-zinc alloy backplanes used in electronic equipment are required to have certain heat dissipation performance. Therefore, it is necessary to evenly set a circle of circular holes on the copper-zinc alloy backplane, which can greatly improve the heat dissipation performance and reduce the weight. Therefore, during the processing, the copper-zinc alloy backplane needs to be drilled with high precision by CNC equipment to meet its heat dissipation requirements.

[0003] At present, there are the following disadvantages when drilling holes in the copper-zinc alloy back plate: 1. When drilling holes in the copper-zinc alloy back plate, it is necessary to first fix the copper-zinc alloy back plate on the drilling machine workbench, and then use the drill bit to drill holes in the corresponding positions one by one. Drilling holes one by one takes a long time, which leads to low production efficiency of the copper-zinc alloy back plate, and it is difficult to keep consistent parameters such as speed, force and position during the drilling process. Therefore, quality problems such as rough hole wall and uneven hole diameter are prone to occur, affecting the overall quality of the product; 2. During the drilling process, the drill bit part is not connected to the clamp that fixes the copper-zinc alloy back plate, which makes the drill bit prone to displacement and vibration during the drilling process, resulting in inaccurate drilling position and angle, thereby affecting the processing accuracy and product quality. At the same time, due to the instability of the drill bit and uneven cutting force during the drilling process, inconsistent hole diameters, rough hole walls, and even problems such as too large or too small hole diameters may occur, resulting in unqualified overall product quality.

[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The support portion 51 includes a first swing arm 511, a second swing arm 512, a connecting plate 513 and an arc-shaped fixing plate 514. The first shaft rod 422 is fixedly sleeved with the first swing arm 511 located between the carrying plate 3 and the fixing plate 421. The second swing arm 512 is installed on the lower end surface of the support arm 411 through a bearing. The telescopic end of the first cylinder 413 passes through the second swing arm 512 and is movably connected to the second swing arm 512. The end of the first swing arm 511 away from the first shaft rod 422 and the end of the second swing arm 512 away from the support arm 411 are fixedly installed with a connecting plate 513. The second swing arm 512 is fixedly installed with an arc-shaped fixing plate 514, and a plurality of holes are drilled through the arc-shaped fixing plate 514 in a circular array.

[0042] During specific operation, after the clamping part 41 and the clamping part 43 complete the fixation of the copper-zinc alloy back plate, the first motor 424 is started to drive the groove wheel lever 425 to rotate. When the groove wheel lever 425 rotates one circle, the groove wheel 423 rotates ninety degrees with the first swing arm 511 through the first shaft rod 422. At this time, the connecting plate 513 is just located on the radial extension line of the limiting slide 431, so that the copper-zinc alloy back plate can be divided into four sectors for drilling processing. The first motor 424 is continued to be started to rotate the drilling part 53 one hundred and eighty degrees, so that the drilling part 53 is located in the rightmost sector, so that the drilling part 53 is moved to the position to be drilled on the copper-zinc alloy back plate.

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The lower pressing part 52 includes a shaped frame 521, a second cylinder 522, a lower pressing plate 523 and a limiting slide bar 524.

The output end of the third motor 534 is connected to the plurality of sleeves 531 through a belt 533.

[0045] During specific operation, after the intermittent portion 42 cooperates with the supporting portion 51 to adjust the drilling portion 53 to the corresponding position, the arc-shaped fixed plate 514 is located directly above the corresponding sector-shaped area of ​​the copper-zinc alloy back plate. At this time, the third motor 534 is started to make it rotate synchronously with the plurality of sleeves 531 through the belt 533, so that the plurality of drill bits 532 rotate synchronously, and then the second air pump fixedly installed on the base 1 is started to drive the lower pressure plate 523 to descend through the second cylinder 522. During this process, the limiting slide bars 524 on the left and right sides maintain the stability of the descent of the lower pressure plate 523. When the lower pressure plate 523 descends with the plurality of drill bits 532 to contact the upper end surface of the copper-zinc alloy back plate, the multiple heat dissipation circular holes in the corresponding sector can be drilled in an integrated manner, thereby reducing the number of overall positioning and the adjustment time, greatly improving the processing efficiency, and at the same time improving the overall processing accuracy. The supporting circular plate arranged at the center of the upper end surface of the carrier plate 3 provides space for the drill bit 532 to descend and drill holes through the copper-zinc alloy back plate.

[0046] After the drilling is completed in this sector, the second cylinder 522 is started in reverse to drive the lower pressure plate 523 to rise and reset, and then the first motor 424 is started to move the drilling part 53 to the next sector through the intermittent part 42, and the drilling operation can be repeated until the drilling of all the heat dissipation circular holes on the copper-zinc alloy back plate is completed.

[0047] See also Figure 1 , Figure 6 and Figure 7 The matching part 61 includes a connecting arm 611, an extrusion plate 612, a fixed cylinder 613 and a matching locking rod 614. The front end surface of the lower pressure plate 523 is fixedly installed with the connecting arm 611 through a set support rod. The lower end surface of the connecting arm 611 is fixedly installed with an extrusion plate 612 that slides through the second swing arm 512. The lower end surface of the extrusion plate 612 is an inclined surface, and the lower end surface of the extrusion plate 612 is provided with a matching groove. The lower end surface of the connecting arm 611 is fixedly installed with a fixed cylinder 613 located behind the extrusion plate 612. The fixing cylinder 613 is slidably connected with a matching locking rod 614 that penetrates the second swing arm 512 through a set spring.

[0048] See also Figure 1 , Figure 4 , Figure 6 and Figure 7The locking portion 62 includes a matching locking block 621, a spring slide bar 622, a limiting connecting plate 623, an insertion rod 624 and a locking hole 625. A matching locking block 621 is fixedly installed on one side wall of the extrusion slider 432 away from each other. A positioning groove is provided on the side wall of the matching locking block 621 away from the corresponding extrusion slider 432. A plug hole matching with the matching locking rod 614 is provided on the upper end surface of the matching locking block 621. A spring slide bar 622 located directly below the matching groove and distributed up and down is slidably installed on the connecting plate 513. The front ends of the spring slide bars 622 distributed up and down are jointly fixedly installed with a limiting connecting plate 623. The rear ends of the spring slide bars 622 distributed up and down are jointly fixedly installed with an insertion rod 624 matching with the positioning groove. A locking hole 625 corresponding to the plug hole is provided on the plug rod 624. The matching locking rod 614 passes through the plug hole and is inserted into the locking hole 625.

[0049] During specific operation, when the lower pressure plate 523 and several drill bits 532 are synchronously lowered, the lower pressure plate 523 will first lower the extrusion plate 612 through the connecting arm 611. At this time, the connecting plate 513 is just located on the radial extension line of the corresponding limiting slide 431, so that the insertion rod 624 is just corresponding to the corresponding alignment groove. When the extrusion plate 612 descends, its lower end surface will first contact the front end surface of the insertion rod 624, and then the insertion rod 624 will be pushed toward the alignment groove along the inclined surface of the lower end of the extrusion plate 612, and the spring slide bar 622 will move in the matching groove. When the front end surface of the insertion rod 624 contacts the rear end surface of the extrusion plate 612, the insertion rod 624 will not continue to move. At this time, the insertion rod 624 is inserted into the alignment groove, and the insertion hole corresponds to the locking hole 625, and the matching locking rod 614 is located above the locking hole 625, and the drill bit 532 has not yet contacted the upper end surface of the copper-zinc alloy back plate.

[0050] Then, the lower pressure plate 523 continues to descend, thereby bringing the matching locking rod 614 down and inserting it into the socket, and then entering the locking hole 625, so that the matching locking rod 614 at this time locks the connecting plate 513 and the extrusion slider 432, thereby locking the drilling part 53 and the clamping part 43 for fixing the copper-zinc alloy back plate on the supporting plate 3. At this time, the lower pressure plate 523 continues to descend to drive the drill bit 532 to drill, wherein the stable connection between the drilling part 53 and the clamping part 43 can avoid relative movement and displacement between the drill bit 532 and the copper-zinc alloy back plate, making the drilling operation more stable. During this process, the spring between the fixed cylinder 613 and the matching locking rod 614 will provide space for the drilling operation of the drill bit 532.

[0051] When the heat dissipation circular holes in this sector are processed, the lower pressure plate 523 rises and raises the extrusion plate 612 and the matching locking rod 614 through the connecting arm 611. The rising of the matching locking rod 614 will release the lock on the insertion rod 624. At this time, the insertion rod 624 will be pulled forward by the action of the spring slide bar 622, so that the front end face of the insertion rod 624 is against the rear end face of the extrusion plate 612. Finally, the insertion rod 624 will be disengaged from the matching locking block 621 and reset under the action of the spring slide bar 622, so that the subsequent drilling operation can continue.

[0052] See also Figure 1 —7. The present invention also provides a processing method using the above-mentioned copper-zinc alloy backplane continuous machining device. The specific processing method includes the following steps: S1. Preparation: prepare the copper-zinc alloy backplane to be processed, and clean the surface of the copper-zinc alloy backplane to ensure that there is no oil stain and impurities on the surface.

[0053] S2. Fixing the workpiece: Place the copper-zinc alloy back plate at the center of the upper end surface of the carrier plate 3, clamp and fix the copper-zinc alloy back plate through the clamping part 43, and then start the first air pump fixed on the base 1 to squeeze the copper-zinc alloy back plate downward through the clamping part 41, so as to implement dual fixation of downward squeezing and side wall clamping on the copper-zinc alloy back plate before drilling.

[0054] S3, adjusting the position: after the pressing part 41 and the clamping part 43 have completed fixing the copper-zinc alloy back plate, the first motor 424 is started to adjust the drilling part 53 to a corresponding position through the cooperation of the intermittent part 42 and the supporting part 51 .

[0055] S4, drilling operation: start the third motor 534 to cooperate with the drilling part 53 and the pressing part 52 to carry the plurality of drill bits 532 down to contact the upper end surface of the copper-zinc alloy back plate, and then perform an integrated drilling operation on the plurality of heat dissipation circular holes in the corresponding sectors.

[0056] When the lower pressing plate 523 and the drill bits 532 are synchronously lowered, the drilling portion 53 and the clamping portion 43 for fixing the copper-zinc alloy back plate are locked on the supporting plate 3 through the cooperation of the stabilizing mechanism 6 and the actuator 4, so that the drilling operation is more stable.

[0057] After the drilling is completed in this sector, the second cylinder 522 is started in reverse to drive the lower pressure plate 523 to rise and reset, and then the first motor 424 is started to move the drilling part 53 to the next sector through the intermittent part 42, and the drilling operation can be repeated until the drilling of all the heat dissipation circular holes of the copper-zinc alloy back plate is completed.

[0058] S5. Subsequent processing: Take out the copper-zinc alloy back plate after drilling, and use a deburring tool to deburr the edge of the drilled hole. At the same time, use a measuring tool to check the drilling position, diameter, etc. to ensure that it meets the design requirements.
