Description

Technical Field

[0001] The present invention relates to the technical field related to reaming processing, and particularly to a streamlined reamer. Background Art

[0002] Reaming is a machining method, specifically referring to the process of using a tool to remove a small amount of material from the inner wall of a workpiece hole to improve its dimensional accuracy and the surface quality of the hole. Currently, the machining methods of reaming are generally divided into two types. The first method is to fix the tool, use a clamping device to clamp the workpiece to be machined, and then drive the workpiece to rotate through a driving device. As the workpiece gradually approaches the tool, the tool cuts the workpiece to complete the reaming operation. The second method is to fix the workpiece on the workbench and drive the tool to rotate through a driving device. As the rotating tool gradually approaches the workpiece to be machined, the tool cuts the workpiece to complete the reaming operation.

[0003] When the existing reaming device processes metal workpieces, it is unable to cool the reaming position, which is extremely likely to cause the temperature of the reaming position to be too high and deformation to occur. Secondly, after the reaming process is completed, the reaming is not directly detected, but instead, it is troublesome to use a vernier caliper manually for detection, and the detection efficiency is low. In view of the above problems, it is necessary to improve the existing equipment. Summary of the Invention

Detailed implementation mode

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-8 , the present invention provides a technical solution: a streamlined reamer, according to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown in the figure, a reaming positioning mechanism 2 is provided in the middle of the upper end of the frame 1. The reaming positioning mechanism 2 includes a support frame 201, a reaming assembly, a driving mechanism and a positioning assembly. A reaming assembly is provided in the middle of the top of the support frame 201. The reaming assembly is connected to the positioning assembly through the driving mechanism. At the same time, the positioning assembly is located below the inside of the support frame 201. Ventilation heads 2091 are symmetrically arranged on the inner side of the middle of the positioning assembly. The two ventilation heads 2091 respectively penetrate through the support frame 201 through the first connecting pipe 212 and the second connecting pipe 216 and are connected to the corresponding three-way connecting heads 213 and blowers 217. At the same time, the other two ports of the three-way connecting head 213 are respectively connected with a dust extraction pump 214 and a dust storage box 215.

[0030] Specifically, the reaming assembly includes a first lifting plate 202, a rotating motor 207 and a reamer body 208. The two sides of the first lifting plate 202 are connected to the corresponding first moving ball nuts on the screw rod body 203. A rotating motor 207 is provided in the middle of the lower end of the first lifting plate 202. At the same time, the output end of the rotating motor 207 is connected to the reamer body 208. The reamer body 208 includes a tool holder and a reamer body. The reamer body is welded to the lower end of the tool holder. At the same time, the reamer body is composed of a plurality of cutting teeth. The plurality of cutting teeth are evenly distributed in a circle along the lower end of the tool holder, and the cutting teeth are arranged at a helix angle, so that the cutting force of the reamer body 208 is decomposed into multiple directions during processing, which not only reduces the cutting resistance, but also makes the reamer more evenly stressed and improves the quality of reaming.

[0031] Specifically, the driving mechanism includes a screw rod body 203. There are four screw rod bodies 203. At the same time, limit blocks 204 are provided at the tops of the four screw rod bodies 203. The lower ends of the two horizontally symmetric screw rod bodies 203 penetrate through the support frame 201 and the positioning sleeve 205 and are connected to the corresponding driving components 206. The driving component 206 includes a protective housing 2061, a worm 2062, a driving motor 2063 and a worm gear 2064. A worm 2062 is horizontally arranged at the rear side inside the protective housing 2061. One end of the worm 2062 penetrates through the protective housing 2061 and is connected to the driving motor 2063. At the same time, the worm gears 2064 meshed on both sides of the front of the worm 2062 are respectively connected to the outer sides of the lower ends of the corresponding screw rod bodies 203. Through the driving mechanism, it is convenient to synchronously drive the reaming assembly and the positioning assembly to move up and down synchronously, improving the practicality of use.

[0032] Specifically, the positioning component includes a second lifting plate 209, a splash-proof side plate 210, and a positioning side plate 211. The two sides of the second lifting plate 209 are connected to the second moving ball nuts correspondingly arranged on the screw rod body 203. The second lifting plate 209 is of a loop structure. At the same time, splash-proof side plates 210 are symmetrically arranged on the left and right sides of the upper end of the second lifting plate 209. Through the splash-proof side plates 210, it is convenient to protect the outside of the reaming position, avoiding the waste chips splashing out during processing and being difficult to clean. Positioning side plates 211 are symmetrically arranged in the middle of the front and rear sides of the lower end of the second lifting plate 209. Through the positioning side plates 211, it is convenient to support the lower end of the second lifting plate 209, preventing the second lifting plate 209 from pressing and deforming the metal workpiece during long-term downward movement, and improving the protection performance during use.

[0033] During use, the driving motor 2063 drives the worm 2062 to rotate, causing the worm 2062 to drive the worm wheel 2064 and the correspondingly connected screw rod body 203 to rotate synchronously, so that the first moving ball nut and the second moving ball nut arranged on the screw rod body 203 drive the first lifting plate 202 and the second lifting plate 209 to move synchronously. Then, under the action of the second lifting plate 209, the metal workpiece is fixed on the upper end of the machine frame 1. Next, the first lifting plate 202 drives the rotary motor 207 and the reaming tool body 208 to move downward, so that the reaming tool body 208 passes through the middle of the second lifting plate 209 and contacts the metal workpiece. Then, the rotary motor 207 drives the reaming tool body 208 to rotate for reaming processing. During the processing, the blower 217 and the dust extraction pump 214 are started, so that the blower 217 blows the external gas into the processing position through the second connecting pipe 216 and the correspondingly connected ventilation head 2091 for cooling. At the same time, the waste chips generated during reaming processing enter the first connecting pipe 212 through another ventilation head 2091 and are transported and stored in the dust storage box 215, thereby improving the practicality during use.

[0034] According to Figure 1 、 Figure 4 、 Figure 7 and Figure 8As shown, the upper end of the frame 1 is symmetrically provided with a first side frame 3 and a second side frame 4 on both sides of the reaming hole positioning mechanism 2, and a loading assembly is arranged inside the first side frame 3, and the loading assembly includes a limiting side plate 5, an electric push rod 6 and a loading push plate 7, and the limiting side plate 5 is symmetrically provided with two limiting side plates 5, and at the same time, the outer sides of the two limiting side plates 5 are connected to the first side frame 3 through the electric push rods 6 arranged at equal distances, and the limiting side plates 5 are pushed to move by the electric push rods 6, so as to limit the channel position for feeding the metal workpiece, so that the metal workpiece is not easily offset during loading, and the loading push plate 7 is located between the two limiting side plates 5, and one side of the loading push plate 7 is connected to the first side frame 3 through the first electric telescopic rod 8 arranged symmetrically, and at the same time, a first electromagnetic block 9 is arranged on the other side of the loading push plate 7, and the loading push plate 7 is pushed to move by the first electric telescopic rod 8, so that the metal workpiece magnetically connected to the first electromagnetic block 9 is moved The material is moved and loaded, and a material guide assembly 11 is arranged on one side inside the second side frame 4, the material guide assembly 11 includes a second electric telescopic rod 1101 and a material guide plate 1102, and two second electric telescopic rods 1101 are symmetrically arranged, and the output ends of the two second electric telescopic rods 1101 are connected to the material guide plate 1102, and a second electromagnetic block 1103 is arranged on the inner side of the bottom end of the material guide plate 1102 close to the reaming hole positioning mechanism 2, and a guide rod 1104 symmetrically arranged on the other side of the material guide plate 1102 penetrates the second side frame 4 and is connected to the connecting side plate 1105, and the material guide plate 1102 is driven to move by the second electric telescopic rod 1101, so that the metal workpiece magnetically connected to the second electromagnetic block 1103 is guided and moved, so that the reamed hole in the processed metal workpiece is located directly below the detection mechanism 12, thereby performing quality inspection on the reamed hole and facilitating the unloading of the metal workpiece.

[0035] according to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown in the figure, a blanking port 10 is provided on one side below the upper end of the frame 1, and a detection mechanism 12 is provided at the top of the second side frame 4 directly above the blanking port 10. At the same time, a support and guiding assembly 13 is provided inside the blanking port 10 near the hinge hole positioning mechanism 2. The support and guiding assembly 13 includes a blanking guide plate 1301, and a through hole 1302 is provided in the middle of the upper end of the blanking guide plate 1301. At the same time, a rotating plate 1303 is rotatably connected inside the through hole 1302. One side of the upper end of the rotating plate 1303 is rotatably connected to the output end of the corresponding third electric telescopic rod 1304, and a connecting rod 1305 is provided on the other side of the upper end of the rotating plate 1303. At the same time, the top of the connecting rod 1305 is rotatably connected to the lower end of the rotating seat 1306. One side of the rotating seat 1306 is rotatably connected to one side inside the blanking port 10. By driving the rotating plate 1303 to rotate through the third electric telescopic rod 1304, the rotating plate 1303 drives the rotating seat 1306 to rotate through the connecting rod 1305. When the rotating seat 1306 is horizontally placed, the rotating seat 1306 can support the bottom of one side of the metal workpiece. When the rotating seat 1306 is obliquely placed, it is convenient for the metal workpiece to be guided and blanked through the blanking port 10 and the blanking guide plate 1301, improving the practicality of use.

[0036] Specifically, the detection mechanism 12 includes a mounting frame 1201, and a guiding frame 12011 is provided in the middle inside the mounting frame 1201. At the same time, a T-shaped frame 1209 is provided inside the middle of the guiding frame 12011. A connecting convex block 1210 is movably connected inside one side of the T-shaped frame 1209, and the other end of the connecting convex block 1210 is connected to the upper end of one side of the rotating frame 1205. At the same time, the lower end of the rotating frame 1205 is connected to the mounting frame 1201 through an electric rotating shaft 1206.

A vertical plate 1203 is provided on the cross bar 1202, and a pressing seat 1204 is provided at the lower end of the vertical plate 1203. Through the pressing seat 1204, it is convenient to position the upper end of the metal workpiece near one side of the hinge hole positioning mechanism 2.

[0037] During use, the electric rotating shaft 1206 drives the rotating frame 1205 to rotate. When the rotating frame 1205 compresses the buffer spring 1208, the T-shaped frame 1209 moves upward under the action of the connecting bump 1210 and the rotating frame 1205. Conversely, when the rotating frame 1205 pulls the buffer spring 1208 to stretch, the T-shaped frame 1209 moves downward under the action of the connecting bump 1210 and the rotating frame 1205, causing the detection block 1211 to move downward synchronously to contact the reamed hole. When the bottom of the lower end of the detection block 1211 is at the same horizontal plane as the metal workpiece, the depth of the reamed hole is detected by the distance measuring instrument 1212. Then the detection block 1211 continues to move downward, causing the induction sleeve 1213 to contact the inner wall of the reamed hole, thereby detecting the size of the reamed hole and improving the practicality of use.
