Description

Technical Field

[0001] The invention relates to the field of machining calculation of spatial angle holes of parts, and in particular to a machining device and method for rapidly machining double-angle holes. Background Art

[0002] There are two main processing methods for the spatial angle hole (double angle) of the pump housing of the straight-axis plunger pump: the first is to fix the pump housing on the standard boring machine. In reality, it is processed on the coordinate boring machine. The preparation time for each product is 4 hours, because before processing, the turntable starting angle and the horizontal rotation angle of the turntable on the workbench must be calculated according to the drawing size, and then the product is installed on the turntable for alignment, the ball is pressed to measure the coordinate points, and the coordinate values ​​of the intersection of the drilled holes are calculated by trigonometric functions from the measured coordinate points, and then processing is performed; the processing efficiency for batch products is very low, and the coordinate boring machine is a precision machine tool, which does not allow batch products to be processed. The second method is: put the shell part to be processed on the machining center for processing.

[0003] There are two disadvantages in using the two existing methods. The preparation time and processing time of the first method are relatively long, and the production efficiency needs to be improved.

At the same time, in terms of the difficulty and matching of part processing size, using high-efficiency equipment to process ordinary holes will also result in over-utilization of equipment.

Since the coordinate boring machine is a precision machine tool, it is not allowed to process batch products. At the same time, the preparation time for processing each product by coordinate boring is 4 hours, because before processing, the turntable starting angle and the horizontal rotation angle of the turntable on the workbench must be calculated according to the drawing size, and then the product is installed on the turntable for alignment, the ball is pressed to measure the coordinate points, and the intersection coordinate values ​​of the drilled holes are calculated by trigonometric functions from the measured coordinate points, and then the processing is performed; the processing efficiency for batch products is very low; if the processing is performed by a machining center (so the accuracy of the hole is not required), the public resources of high-precision processing equipment are occupied, which is not conducive to the rational use of high-precision equipment to maximize its effectiveness, and at the same time increases the processing cost of parts. If this special device is used for processing, it does not need to take the aforementioned 4 hours of preparation time, and the processing time is about 10 minutes each, which greatly improves the production efficiency of batch parts.

DETAILED DESCRIPTION

[0031] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the listed embodiments.

[0032] [Example 1]

[0033] like Figures 1 to 9As shown, a processing device for quickly processing double-angle holes in this embodiment is used to process double-angle holes 200 on a part 100, and the part 100 is a pump casing. The processing device includes a base 1, a support 15 and a drilling template 19. The base 1 has a bottom surface 301 and an inclined surface 302. There is a base angle α between the inclined surface 302 and the bottom surface 301. The base 1 is provided with a positioning bushing 3 for positioning the part on the inclined surface 302. The positioning bushing 3 is fixed by a screw 2. The support 15 is vertically arranged on the base 1, and the drilling template 19 is arranged on the support 15. The drilling template 19 is provided with a drill sleeve 16. The through hole of the drill sleeve 16 is vertically arranged. There is a spacing L1 between the center line A of the drill sleeve 16 and the center line B of the positioning bushing, and there is a spacing L2 between the center C of the drill sleeve 16 and the horizontal center line D of the part (such as Figure 4 As shown), the base angle α, spacing L1 and spacing L2 are obtained by the angle of the double-angle hole. Specifically, the double-angle hole is an inclined hole, and the angle of the inclined hole is in two directions (on two planes, not parallel to any plane), through the base angle α, the drill sleeve center line A, and the line B formed by the intersection of the drill sleeve center line and the positioning bushing center line (the distance L1 between A and B, the distance L2 between the drill sleeve center and the horizontal center line of the workpiece). In the above technical solution, by converting the angle of the double-angle hole into the base angle α, spacing L1 and spacing L2, the part 100 can be processed by placing it on the base 1, without the aforementioned 4 hours of preparation time, and the processing time is about 10 minutes each, which greatly improves the production efficiency of batch parts. At the same time, this special processing device is not easy to replace. If it breaks down or needs to be repaired, it only needs to repair and replace the quick-change drill sleeve. At the same time, the processing hourly cost of an ordinary drilling machine is much lower than that of a machining center, which greatly saves the processing cost.

[0034] In this embodiment, the base 1 and the support 15 are positioned by the positioning pin 10 and locked by the screw 11, so as to facilitate the assembly and disassembly of the base 1 and the support 15. The drilling template 19 and the top of the support 15 are positioned by the latch 9, and the outer diameter of the latch 9 is The matching with the inner holes of bushing 6, bushing 18 and bushing 7 is clearance matching, and the matching clearance is 0.005-0.01, so that it is convenient to assemble and disassemble the drilling template 19 and the support 15. A pin 8 is provided between the drilling template 19 and the support 15. When the pin 9 is taken out, the drilling template 19 can rotate relative to the support 15, thereby driving the drill sleeve 16 to move, which is convenient for positioning and installing parts. The base 1 includes a connecting block 303 and a supporting part 304. A pin 12 is provided between the connecting block 303 and the supporting part 304 and is fixedly connected by welding. Through the above technical scheme, the base, support and drilling template can be replaced according to different double-angle holes, which is convenient for assembly and disassembly, easy to process and low in cost.

[0035] In this embodiment, the double angle hole 200 extends inward from the end face 101 of the part 100. When the part 100 is installed on the base 1, the end face 101 is parallel to the inclined surface 302, and the drill sleeve 16 corresponds to the end face 101, so that the drill sleeve 16 is aligned with the double angle hole 100 after the part 100 is installed, and the drill rod is drilled through the drill sleeve 16. Figure 1 and Figures 3 to 5 As shown, in this embodiment, the double-angle hole is at an angle of 85°±30′ with the X-axis, and at an angle of 6° with the Y-axis in the 85° plane, α=50020′0.27″, L2==13.606, L1==91.73. Through the above technical solution, the two angles of the double-angle hole can be converted, and the position and angle of the drill sleeve can correspond to the position and angle of the required processing hole. During processing, there is no need for calculation, and the double-angle hole can be processed by simply correcting the drill sleeve.

[0036] In this embodiment, the outer circle of the drill sleeve 16 and the inner hole of the bushing 17 are clearance-fitted and are compressed by a compression member 20, which is a screw. When the drill sleeve needs to be replaced or repaired, the compression screw is loosened to remove the drill sleeve. The part 100 has a positioning portion 102, and the outer circle of the positioning portion 102 is With inner hole (See Figure 5 ) are clearance-fitted, with 13 pairs of directional pins on the part holes (See Figure 2 ) is oriented so that part 100 can be securely mounted on the base.

[0037] [Example 2]

[0038] The present embodiment provides a processing method for quickly processing double-angle holes, using the processing device described in Example 1, including the following steps: S1: According to the angle between the double-angle hole 200 and the X-axis and the Y-axis, the base angle α and the space angle β are obtained; S2: The space angle β is projected into the plane rectangular coordinate system, and after coordinate translation, the new coordinates are obtained relative to the origin coordinates X′, Y′; S3: The coordinate system Xa, Ya, L2=Ya of the base angle α is calculated; the intersection size L1 of the drill template is calculated; S4: The part 100 is clamped on the processing device, and after the clamping is completed, the drill bit of the drilling machine is used to complete the pre-processing correction of the drill sleeve, and then the double-angle hole 200 is processed; S5: After the processing is completed, the part is taken out. In the above technical solution, by converting the two angles of the double-angle hole into the base angle α of the processing device and the distance between the drill sleeve and the part, the processing process does not require 4 hours of preparation time as required by a precision coordinate boring machine, thereby improving the production efficiency of the parts; in addition, ordinary machine tools can be used for processing, and the processing hourly cost of an ordinary drilling machine is much lower than that of a machining center, which greatly saves processing costs.

[0039] In this embodiment, in step S1, the double-angle hole is at an angle of 85°±30′ with the X-axis, and at an angle of 6° with the Y-axis in the 85° plane, a=arctg(tg60 / cos850)=50020′0.27″, β=arctg(tg(900-850) / cosα=7048′15.8″. The horizontal rotation angle is thus obtained through stereo calculation, and the space angle and the base angle are obtained from the horizontal rotation angle.

[0040] In this embodiment, in step S2, the new coordinates are X'=34.4+x=48.626, Y'=62.8+y=79.955; in step S3, Xa=48.626 / cosa+16.776=92.585, Ya=cosα×21.315=13.606, L1=cosβ×92.585=91.73. The above technical solution can determine the base angle α, spacing L1 and spacing L2 of the processing device.

[0041] In this embodiment, in step S1, before processing, the pin 9 is lifted, the drilling template 19 is first rotated 180 degrees with the pin 8 as the axis, and then the outer circle of the part is Put into the hole Positioning is performed in the Put it into the directional pin 13 for orientation, and finally use the nut 14 and the washer 5 to press the part. The above technical solution can quickly position and install the parts, which is convenient for operation. In step S5, after the processing is completed, lift the latch 9, first rotate the drilling template 19 180 degrees with the pin 8 as the axis, then loosen the nut 14, and finally take out the processed parts, so as to quickly take out the parts.

[0042] The original technology is to use a precision coordinate boring machine or a machining center to process this space inclined hole. Because the coordinate boring machine is a precision machine tool, it is not allowed to process batch products. At the same time, the preparation time for processing each product with a coordinate boring machine is 4 hours. Before processing, the turntable starting angle and the horizontal rotation angle of the turntable on the workbench must be calculated according to the drawing size, and then the product is installed on the turntable for alignment, the ball is pressed to measure the coordinate points, and the intersection coordinate values ​​of the drilled holes are calculated by trigonometric functions from the measured coordinate points before processing; the processing efficiency for batch products is very low; if the machining center is used for processing (so the hole accuracy requirement is not met), the public resources of high-precision processing equipment are occupied, which is not conducive to the rational use of high-precision equipment to maximize its effectiveness, and at the same time increases the processing cost of parts. If this special device is used for processing, it does not need to take the aforementioned 4 hours of preparation time, and the processing time is about 10 minutes each, which greatly improves the production efficiency of batch parts. At the same time, this special processing device is not easy to replace. If it breaks down or needs to be repaired, only the quick-change drill sleeve needs to be repaired and replaced. At the same time, the processing hourly cost of an ordinary drilling machine is much lower than that of a machining center, which greatly saves the processing cost. Therefore, the processing device and method for quickly processing double-angle holes in this embodiment firstly improve the production efficiency of parts, secondly improve the reasonable utilization rate of equipment and reduce the occupancy rate of unnecessary public high-efficiency equipment, and thirdly reduce the cost of parts processing.
