Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the processing of the toothed heat sink, particularly to a toothed machine machining calibration structure. BACKGROUND

[0002] The toothed heat sink is a common heat dissipation element and is widely used in many fields such as electronic devices. Its working principle is to increase the heat dissipation area to quickly dissipate heat, so as to ensure the normal operation of the equipment. In the production and manufacturing process of the toothed heat sink, the calibration accuracy between the tool and the jig plays a crucial role in the quality of the product.

[0003] At present, the industry generally adopts a single-point tool setting method for the calibration between the tool and the jig of the toothed heat sink. The single-point tool setting method refers to selecting a specific point on the tool and the jig, adjusting the position of the point on the tool and the jig to correspond to each other, and determining the relative position relationship between the tool and the jig. This method can meet the production calibration needs of most toothed heat sinks in a long period of time in the past, and has the advantages of relatively simple operation and low cost.

[0004] However, with the continuous development of science and technology, electronic devices and other products are gradually developing towards miniaturization and integration, and the size requirements for toothed heat sinks are becoming smaller and smaller. The miniaturized toothed heat sink has higher requirements for the accuracy of the tooth and the matching accuracy between the tool and the jig under the condition of unchanged or even higher heat dissipation performance.

[0005] The single-point tool setting method has obvious limitations and cannot adapt to the trend of continuously reducing the size of the toothed heat sink. Since the single-point tool setting method only determines the position relationship between the tool and the jig according to one point, it cannot fully reflect the parallelism of the tool and the jig on the entire working surface. When the size of the toothed heat sink is small, even if the tool and the jig are accurately calibrated at a single point, there may still be a small angle deviation or non-parallelism at other positions. This small deviation may have little effect on the production of large toothed heat sinks, but for small toothed heat sinks, it will cause problems such as uneven thickness and inconsistent height of the tooth, seriously affecting the heat dissipation performance and overall quality of the toothed heat sink, reducing the yield of the product, and increasing the production cost.

[0006] Therefore, in order to improve the production quality of the toothed heat sink and meet the accuracy requirements of the miniaturized toothed heat sink, a new calibration method is urgently needed to replace the existing single-point tool setting method to improve the parallelism calibration accuracy between the tool and the jig.

[0029] As Figure 1As shown, a kind of chisel tooth machine processing calibration structure 10, including chisel tooth assembly 100 and calibration assembly 200, chisel tooth assembly 100 includes transverse moving carrier 110, driving arm 120, jig 130 and cutter 140, jig 130 is set on transverse moving carrier 110, cutter 140 is set on driving arm 120, calibration assembly 200 includes first slider 210, first calibration instrument 220, second slider 230 and second calibration instrument 240, first slider 210 is set on transverse moving carrier 110 along the lateral sliding, first calibration instrument 220 is set on first slider 210, first slider 210 is used to force to drive first calibration instrument 220 to slide relative to transverse moving carrier 110, so that the detection end of first calibration instrument 220 detects the distance with cutter 140, second slider 230 is set on driving arm 120 along the lateral sliding, second calibration instrument 240 is set on second slider 230, second slider 230 is used to force to drive second calibration instrument 240 to slide relative to driving arm 120, so that the detection end of second calibration instrument 240 detects the distance with jig 130.

[0030] It should be noted that the horizontal moving carrier 110 is used to drive the jig 130 to move linearly along the X-axis, and the driving arm 120 is used to drive the cutter 140 to move linearly along the Z-axis. In an embodiment, the horizontal moving carrier 110 and the driving arm 120 are corresponding X-axis and Z-axis driving modules in the gear shaping machine, which are servo modules driven by motors, which are prior art and will not be described here. Further, the jig 130 is installed on the horizontal moving carrier 110, and the jig 130 is used to fix the gear-shaped heat sink, and the cutter 140 is installed on the driving arm 120, and under the cooperation of the horizontal moving carrier 110 and the driving arm 120, the cutter 140 completes the gear shaping of the gear-shaped heat sink. The jig 130 and the cutter 140 are detachably installed relative to the gear shaping machine, and the parallelism between them needs to be kept within a certain error to ensure the machining accuracy of the gear-shaped heat sink, otherwise it will be difficult to keep the thickness of the gear-shaped heat sink consistent. In order to improve the parallelism between the cutter 140 and the jig 130, a calibration assembly 200 is arranged to calibrate the parallelism. Specifically, the first sliding block 210 is slidably installed on the end of the horizontal moving carrier 110, and the first calibration instrument 220 is installed on the first sliding block 210. In this way, after the detection end of the first calibration instrument 220 is butted against a point of the cutter 140, an external force is applied to the first sliding block 210 to make it slide relative to the horizontal moving carrier 110, so as to drive the detection end of the first calibration instrument 220 to laterally detect the distance between the cutter 140. In this way, whether the cutter 140 is installed along the horizontal line can be quickly determined by the first calibration instrument 220, so that the cutter 140 can be quickly horizontally calibrated. Further, the second sliding block 230 is slidably installed on the driving arm 120, and the second calibration instrument 240 is installed on the second sliding block 230, and the detection end of the second calibration instrument 240 is butted against the jig 130. An external force is applied to the second sliding block 230, so that the second calibration instrument 240 detects the distance between the jig 130 along the transverse direction, thereby quickly horizontally calibrating the jig 130. In this way, under the action of the calibration assembly 200, the cutter 140 and the jig 130 are kept within the allowable error of parallelism, thereby improving the machining quality of the gear-shaped heat sink.

[0031] As Figure 1 shown, in an embodiment, the horizontal moving carrier 110 includes a driving member 111 and a carrier table 112, the carrier table 112 is arranged on the driving member 111, the jig 130 is arranged on the carrier table 112, and the first sliding block 210 is slidably arranged on one end of the carrier table 112.

[0032] It should be noted that in order to make the notching of the notched heat sink at a certain angle, the transverse carrying part 110 is arranged in a combination structure of the driving part 111 and the carrying table 112, wherein the driving part 111 is a servo module driven by a motor, and the carrying table 112 is installed on the driving part 111. In an embodiment, the carrying table 112 is arranged obliquely, that is, the surface of the carrying table 112 has a certain angle with the horizontal plane. The jig 130 is installed on the carrying table 112 by screws, and the first sliding block 210 is slidingly installed on the higher end of the carrying table 112.

[0033] As shown in Figure 1 , in an embodiment, a first sliding groove 211 is formed on one of the carrying table 112 and the first sliding block 210, and a first sliding rail 250 is arranged on the other one, and the first sliding rail 250 is slidingly connected with the first sliding groove 211 in a matched manner.

[0034] It should be noted that in an embodiment, the first sliding groove 211 is formed on the carrying table 112, and the first sliding rail 250 is arranged on the first sliding block 210. In another embodiment, the first sliding rail 250 is arranged on the carrying table 112, and the first sliding groove 211 is formed on the first sliding block 210. Whether it is the first embodiment or the second embodiment, as long as the first sliding rail 250 passes through the first sliding groove 211, the first sliding block 210 can stably slide relative to the carrying table 112.

[0035] As shown in Figure 1 , in an embodiment, a second sliding groove 231 is formed on one of the driving arm 120 and the second sliding block 230, and a second sliding rail 260 is arranged on the other one, and the second sliding rail 260 is slidingly connected with the second sliding groove 231 in a matched manner.

[0036] It should be noted that in an embodiment, the second sliding groove 231 is formed on the driving arm 120, and the second sliding rail 260 is arranged on the second sliding block 230. In another embodiment, the second sliding rail 260 is arranged on the driving arm 120, and the second sliding groove 231 is formed on the second sliding block 230. In this way, as long as the second sliding rail 260 passes through the second sliding groove 231, the second sliding block 230 can stably slide relative to the driving arm 120.

[0037] Further, in an embodiment, the extension line of the sliding direction of the first sliding block 210 is parallel to the extension line of the sliding direction of the second sliding block 230.

[0038] In this way, the first sliding block 210 and the second sliding block 230 are in a parallel state, that is, in a stable reference state, so that the first calibrator 220 / second calibrator 240 can drive the tool 140 / jig 130 to calibrate the levelness, respectively.

[0039] In an embodiment, the first calibrator 220 and the second calibrator 240 are laser distance meters or micrometers. Specifically, when the first calibrator 220 and the second calibrator 240 are laser distance meters, the first calibrator 220 does not need to be in direct contact with the tool 140 when calibrating the tool 140 horizontally, and the second calibrator 240 does not need to be in direct contact with the jig 130 when calibrating the jig 130 horizontally. When the first calibrator 220 and the second calibrator 240 are micrometers, the detection end of the first calibrator 220 abuts against the tool 140 to perform horizontal detection, and the detection end of the second calibrator 240 abuts against the jig 130 to perform horizontal detection. The laser distance meter is relatively expensive, and the micrometer is relatively cheap. The specific calibrator can be selected according to the actual budget.

[0040] In an embodiment, the first calibrator 220 and the first sliding block 210 are fixed by magnetic attraction or screwing.

[0041] Specifically, the first calibrator 220 can be fixed on the first sliding block 210 by a magnetic material, so that the first calibrator 220 is convenient to take and place. Further, the first calibrator 220 and the first sliding block 210 can be locked and fixed by a screw. Similarly, the second calibrator 240 can also be fixed on the second sliding block 230 by a magnetic material, so that the second calibrator 240 is convenient to take and place. Further, the second calibrator 240 and the second sliding block 230 can also be locked and fixed by a screw.

[0042] The above-described embodiments only express several embodiments of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the application. In the present application, the installation / fixed / setting can be understood as including but not limited to locking and fixing by screws / wrenches, unless otherwise defined.
