Description

Technical Field

[0001] The present invention relates to the technical field of machining of medium support parts, and particularly relates to a machining device for medium support parts. Background Art

[0002] The medium support part is used to support two parts and plays the roles of weight reduction and insulation. For the machining of the medium support part as shown in Figure 1 The traditional machining method is as follows: First, the blank is turned into a cylindrical blank part with the diameter and length required by the process using a lathe. Then, the blank part is clamped by a vise, and the cylindrical blank part is cut in half by a milling machine to obtain two half-blank parts. Then, the middle groove on the plane of the half-blank part is milled, and finally, after turning the half-blank part over, two stepped concave cavities on its curved surface are machined. Since the material of this medium support part is composite foam material, which is soft and fragile, the method of clamping with a vise not only makes it difficult to guarantee the machining accuracy and the product qualification rate is low, but also the alignment time and other clamping auxiliary times consumed in the actual machining process are long, resulting in low effective utilization rate of the milling machine and large labor intensity of the machining operator. Summary of the Invention

[0003] The purpose of the present invention is to provide a machining device for medium support parts, which is used to cooperate with a milling machine to replace a vise to fix the blank part, and is convenient for the milling cutter of the milling machine to cut, mill the middle groove and mill the concave cavity.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A machining device for medium support parts fixes a cylindrical blank part and cooperates with a milling machine to machine the blank part into a medium support part, including a splitting and grooving device and a batch cavity-opening device. The splitting and grooving device includes a main body. A positioning round hole and a splitting long groove are formed on the main body, and the two are communicated. The splitting long groove penetrates through the positioning round hole and passes through the center of the positioning round hole. The positioning round hole is adapted to the blank part, and the blank part can be inserted into the positioning round hole. A clamping block is arranged on one side of the main body, and a positioning plate is arranged on the other side. The two sides are adjacent. A cutter slot is formed on the side of the positioning plate close to the clamping block. The batch cavity-opening device includes a base and a positioning block. A semicircular groove is formed through the side of the positioning block facing the base. The semicircular groove is adapted to the half-blank part. A front cutting groove and a rear cutting groove are formed on the positioning block along the length direction. After the blank part is inserted into the semicircular groove, the arc surface part thereof protrudes upward from the front cutting groove and the rear cutting groove.

[0006] Preferably, there are two clamping blocks arranged oppositely on the splitting and grooving device, and the distance between the two clamping blocks is adapted to the diameter of the blank part.

[0007] Preferably, a guiding groove is formed between the two clamping blocks, and the guiding groove is communicated with the cutter slot.

[0008] Preferably, at least two mounting holes are arranged in parallel on the positioning plate, and one docking hole is arranged on the main body. When any one of the mounting holes is coaxial and concentric with the docking hole, the positioning plate and the main body are fixedly connected by connecting nails. When different mounting holes are connected to the docking hole, the cutting groove protrudes from the main body by different lengths.

[0009] Preferably, the slitting long groove is opened inward from one side of the main body and penetrates through the other two adjacent sides of the main body on this side.

[0010] Preferably, the front cutting groove is "L"-shaped, and the semi-finished part can be inserted into the semi-circular groove through the "L"-shaped opening of the front cutting groove.

[0011] Preferably, a limiting platform protrudes upward on the base, and the limiting platform is located near the rear cutting groove. The semi-finished part can be inserted into the semi-circular groove and blocked by the limiting platform.

[0012] Preferably, at least two semi-circular grooves are arranged side by side, and one semi-finished part can be inserted into each semi-circular groove.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows: The semi-finished part is first inserted into the positioning circular hole of the slitting and grooving device, and the semi-finished part is divided into two equal parts by the milling cutter of the milling machine passing through the slitting long groove along the length direction to obtain two semi-finished parts; then, one semi-finished part is placed with its plane facing the main body and fixed on the main body by a clamping block, and the middle groove of the semi-finished part is milled by the milling cutter of the milling machine passing through the cutting groove; finally, the semi-finished part is placed with its plane facing the base of the batch cavity-opening device, inserted into the semi-circular groove, and the two concave cavities of the semi-finished part are milled by the milling cutter of the milling machine passing through the front cutting groove and the rear cutting groove to obtain the final dielectric support part. The entire processing process does not require clamping by a vise, nor does it require milling after finding the positions of slitting, grooving, and cavity-opening. The processing accuracy is relatively improved, and thus the product qualification rate is improved; the positions of the center groove and the concave cavities of the dielectric support part have been positioned in this device, and there is no need to spend time on alignment, which relatively improves the effective utilization rate of the milling machine and relatively reduces the labor intensity of the processing operator.

Specific embodiments

[0022] The present invention will be described in detail below with reference to the accompanying drawings.

[0023] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] Please refer to Figures 1 to 7 , a dielectric support part processing device, which is used to fix the cylindrical blank part 8 and cooperate with a milling machine to process the blank part 8 into a dielectric support part 7. The cylindrical blank part 8 is split in half along the length direction to form two semi-finished parts 9. The dielectric support part processing device includes a splitting and grooving device 1 and a batch cavity-opening device 2.

[0025] The slitting and grooving device 1 includes a main body 11. A positioning round hole 111 and a slitting long groove 112 that communicate with each other are vertically bored through the top surface to the bottom surface of the main body 11. The aperture of the positioning round hole 111 is adapted to the diameter of the blank part 8, ensuring that the blank part 8 can be inserted into the positioning round hole 111. The slitting long groove 112 horizontally penetrates the positioning round hole 111 and passes through the center of the positioning round hole 111. The slitting long groove 112 is opened inward from the side surface jointly adjacent to the top surface and the bottom surface of the main body 11. A positioning plate 12 is detachably connected to the top surface of the main body 11. The positioning plate 12 and the positioning round hole 111 are arranged along the length direction of the main body 11 on the top surface of the main body 11. A lower knife groove 121 is opened inward on the side of the positioning plate 12 facing away from the positioning round hole 111; two mounting holes 122 are arranged in parallel on the positioning plate 12, and a docking hole is opened on the top surface of the main body 11. Both the mounting holes 122 and the docking hole are threaded holes. When any one of the mounting holes 122 is coaxial and concentric with the docking hole, the positioning plate 12 and the main body 11 are fixedly connected by passing a connecting nail 123 through the mounting hole 122 and the docking hole. The connecting nail 123 is a threaded nail; when the two mounting holes 122 are connected to the docking hole, the lower knife groove 121 protrudes transversely from the main body 11 by different lengths. A clamping block 13 is detachably connected to the side surface of the main body 11. The clamping block 13 is located on the opposite surface of the main body 11 where the slitting long groove 112 is opened. Threaded holes are opened on both the clamping block 13 and this surface of the main body 11, and the two are fixedly connected by screwing screws into the threaded holes. The distance between the two clamping blocks 13 is adapted to the diameter of the blank part 8, ensuring that the blank part 8 can be stably clamped between the two clamping blocks 13. At this time, the positioning plate 12 is located above the blank part 8 and contacts the top surface of the blank part 8; a guiding groove 113 is vertically opened on the main body 11 between the two clamping blocks 13. The guiding groove 113 is located directly below the lower knife groove 121 and is perpendicular to it.

[0026] The batch cavity opening device 2 includes a base 21 and a positioning block 22 located above the base 21. The two are detachably connected. Threaded holes are provided on both the base 21 and the positioning block 22, and the two are connected and fixed by screwing screws into the threaded holes. A limiting platform 211 protrudes upward from the top surface of the base 21, and its longitudinal section is "L"-shaped; one side of the positioning block 22 contacts the limiting platform 211. The positioning block 22 is provided with a front cutting groove 221 and a rear cutting groove 222 along the length direction. The front cutting groove 221 is far from the limiting platform 211, and the rear cutting groove 222 is close to the limiting platform 211; the longitudinal section of the front cutting groove 221 is "L"-shaped, and its opening faces away from the limiting platform 211; the longitudinal section of the rear cutting groove 222 is "U"-shaped, and its opening faces upward; the positioning block 22 is provided with an arched semi-circular groove 223 inward from the surface facing the base 21. The semi-circular groove 223 is adapted to the semi-finished part 9, that is, the semi-finished part 9 can be inserted into the semi-circular groove 223. The semi-circular groove 223 runs through the width direction of the positioning block 22. Four semi-circular grooves 223 are arranged side by side, and one semi-finished part 9 can be inserted into each semi-circular groove 223, so that the semi-finished part 9 can open concave cavities 72 in batches, and further enable the medium support part 7 to be produced in batches. After the semi-finished part 9 is inserted into the semi-circular groove 223, the arc part of it protrudes upward from the front cutting groove 221 and the rear cutting groove 222.

[0027] The specific usage method of this device is as follows:

[0028] Insert the cylindrical blank part 8 into the positioning round hole 111, and use the milling cutter of the milling machine to pass through the slitting long groove 112 along the length direction to cut the cylindrical blank part 8 into two identical semi-cylindrical semi-finished parts 9;

[0029] Face the plane of the semi-finished part 9 towards the main body 11, use the clamping block 13 to clamp and fix the semi-finished part 9, and use the milling cutter of the milling machine to go down from the tool slot 121 and pass through along the length direction of the guiding groove 113 to mill the middle part of the plane of the semi-finished part 9 along the length direction to form the middle groove 71;

[0030] Face the plane of the semi-finished part 9 with the milled middle groove 71 towards the base 21, insert it into the semi-circular hole from the end of the semi-circular hole located in the front cutting groove 221 until the end of the semi-finished part 9 touches the limiting platform 211 and stops. Use the milling cutter of the milling machine to mill the bottom surfaces of the front cutting groove 221 and the rear cutting groove 222, and mill off the part of the arc surface of the semi-finished part 9 that protrudes from the front cutting groove 221 and the rear cutting groove 222 to form two concave cavities 72.

[0031] The medium support part 7 is processed.

[0032] Using this device to process the medium support part 7 can achieve rapid and accurate clamping and alignment of the part, and at the same time can prevent the deformation of the medium support part 7 during the processing. By designing two clamping devices, namely the split slotting device 1 and the batch cavity opening device 2, the clamping of the blank part 8 can be carried out outside the milling machine, without occupying the processing time of the milling machine. While improving the actual production efficiency and the utilization rate of the machine tool, it ensures the quality of the processed products, greatly reduces the labor intensity of frequently clamping parts, and saves the production cost.
