Description

Technical Field

[0001] This utility model belongs to the field of hat-shaped tool magazine technology, and in particular relates to a hat-shaped tool magazine moving mechanism. Background Technology

[0002] In the field of CNC machine tool processing, the bucket-type tool magazine is widely used in small and medium-sized machining centers due to its advantages such as compact structure and low cost, and is especially suitable for mold manufacturing, batch processing of parts and other scenarios.

[0003] The existing hat-shaped tool magazine moving mechanism mainly achieves tool exchange through a combination of circular rotation for tool selection and linear movement for tool changing. However, the existing hat-shaped tool magazine moving mechanism has a relatively complex stroke during tool exchange. It requires first moving the tool holder below the spindle, then moving the spindle down to put the tool into the tool holder. At this time, the tool holder continues to move down and rotate to place the new tool below the spindle. Then it moves up to complete the entire replacement process. This method is time-consuming, resulting in low overall tool changing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a hat-shaped tool magazine moving mechanism. Specifically, a starting motor drives a bidirectional lead screw to rotate clockwise, causing the disc to move to the right, with the switching port facing the spindle. A second starting motor drives the tool holder to rotate via gears, moving the idle position to the switching port for tool return. After tool return is complete, the second starting motor drives the tool holder to continue rotating, and the spindle replaces the tool. This design ensures that the disc only needs to move twice and the tool holder only needs to rotate twice during the entire tool replacement process, significantly shortening the travel path and reducing the time spent on tool replacement. This solves the problem of existing hat-shaped tool magazine moving mechanisms having a long tool replacement process, leading to increased time consumption and lower overall tool replacement efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a hat-shaped tool magazine moving mechanism, comprising a hat-shaped tool magazine including a plurality of tools, and further comprising:

[0007] A moving mechanism, disposed outside a plurality of cutting tools, the moving mechanism being used to move the plurality of cutting tools; and

[0008] A locking mechanism is provided at the center of the outer surface of the tool, and the locking mechanism is used to fix the tool.

[0009] Furthermore, the moving mechanism includes a moving tube with a moving groove at the bottom. A bidirectional lead screw is rotatably connected inside the moving tube. A motor is fixedly connected to the right side of the moving tube, and the left output end of the motor is fixedly connected to the right side of the bidirectional lead screw via a coupling.

[0010] Furthermore, an annular moving block is slidably connected to the outer surface of the bidirectional lead screw, and the annular moving block is slidably limited to the inner wall of the moving tube. A fixed cage is fixedly connected to the bottom of the annular moving block, and an electric push rod is fixedly connected inside the fixed cage. A fixed plate is fixedly connected to the bottom output end of the electric push rod.

[0011] Furthermore, a disc is fixedly connected to the bottom of the fixed disc, the disc has a hollow interior, a switching port is opened on the front of the disc, a fixed shaft is rotatably connected to the center of the disc, and a tool holder is fixedly connected to the center of the outer surface of the fixed shaft.

[0012] Furthermore, anti-detachment rings are fixedly connected to the top and bottom of the outer surface of the fixed shaft. The two anti-detachment rings, with their opposite sides, abut against the top and bottom of the inner wall of the disc, respectively. Several teeth are fixedly connected to the outer surface of the fixed shaft. A second motor is fixedly connected to the top of the inner wall of the disc. A gear is fixedly connected to the bottom output end of the second motor. The gear meshes with several teeth.

[0013] Furthermore, the locking mechanism includes several mounting blocks, the bottom of which is fixedly connected to the top of the tool holder. The mounting blocks are arranged in a ring on the top of the tool holder. An arc-shaped block is fixedly connected to one side of each mounting block that is far apart from each other. Two fixing claws are fixedly connected to one end of each mounting block that is far apart from each other. The two fixing claws are symmetrically arranged.

[0014] Furthermore, the fixed claw has a second movable groove inside, and the top and bottom of the second movable groove are both provided with limit grooves. The inner wall of the second movable groove is slidably limited by a clamping block. The two clamping blocks are fixedly connected to the side of each other that is close to each other. The top and bottom of each clamping block are fixedly connected to limit blocks. The limit blocks are slidably limited by the limit grooves. The inner wall of the second movable groove is fixedly connected to two springs. The other end of each spring is fixedly connected to the side of the clamping block away from the arc-shaped block.

[0015] Furthermore, an annular groove is formed at the center of the outer surface of the cutting tool, and the first arc block and the two second arc blocks are all arc-shaped. The first arc block and the two second arc blocks are adapted to the annular groove. The first arc block and the two second arc blocks are all made of rubber, which can effectively prevent the cutting tool from being damaged by impact.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a moving mechanism, specifically, starts a motor one to drive a bidirectional lead screw to rotate clockwise, the disc moves to the right, and the switching port faces the main shaft. Starts a motor two to drive the tool holder to rotate through gears, turning the idle position to the switching port, and then returning the tool. After the tool is returned, restarts motor two to drive the tool holder to continue rotating, and the main shaft replaces the new tool. This setting means that the disc only needs to move twice and the tool holder only needs to rotate twice during the entire replacement process, which greatly shortens the travel path during the entire replacement process and significantly reduces the time spent on replacement.

[0018] 2. This utility model features a locking mechanism. Specifically, when the disc moves to the right, the spindle tool contacts the inclined surface of the clamping block and is pressed into the second moving groove, which in turn compresses the spring. When the annular groove of the tool contacts the first arc-shaped block, the disc stops moving, the spring returns to its original position, and pushes the clamping block so that the second arc-shaped block is engaged in the annular groove, thus completing the clamping and fixing of the tool. This feature can automatically lock the tool, which takes less time than the traditional mechanical gripper used to fix the tool.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 As shown, this utility model is a hat-shaped tool magazine moving mechanism, including a hat-shaped tool magazine 1, which includes a plurality of tools 11, and also includes:

[0030] Moving mechanism 2, disposed outside a plurality of cutting tools 11, is used to move the plurality of cutting tools 11; and

[0031] The locking mechanism 3 is located at the center of the outer surface of the tool 11 and is used to fix the tool 11.

[0032] The moving mechanism 2 includes a moving tube 21, a moving groove 211 at the bottom of the moving tube 21, a bidirectional lead screw 212 rotatably connected inside the moving tube 21, a motor 213 fixedly connected to the right side of the moving tube 21, and the left output end of the motor 213 fixedly connected to the right side of the bidirectional lead screw 212 through a coupling.

[0033] A ring-shaped moving block 214 is slidably connected to the outer surface of the bidirectional lead screw 212. The ring-shaped moving block 214 is slidably limited to the inner wall of the moving tube 21. A fixed cage 215 is fixedly connected to the bottom of the ring-shaped moving block 214. An electric push rod 216 is fixedly connected inside the fixed cage 215. A fixed plate 217 is fixedly connected to the bottom output end of the electric push rod 216.

[0034] A disc 22 is fixedly connected to the bottom of the fixed disc 217. The disc 22 has a hollow interior. A switching port 221 is opened on the front of the disc 22. A fixed shaft 222 is rotatably connected to the center of the disc 22. A tool holder 223 is fixedly connected to the center of the outer surface of the fixed shaft 222.

[0035] Anti-detachment rings 224 are fixedly connected to the top and bottom of the outer surface of the fixed shaft 222. The opposite sides of the two anti-detachment rings 224 abut against the top and bottom of the inner wall of the disc 22, respectively. Several teeth 225 are fixedly connected to the outer surface of the fixed shaft 222. A second motor 226 is fixedly connected to the top of the inner wall of the disc 22. A gear 227 is fixedly connected to the bottom output end of the second motor 226. The gear 227 meshes with the several teeth 225. When the first motor 213 is started, it drives the bidirectional lead screw 212 to rotate clockwise, and the disc... 22 moves to the right, the switching port 221 faces the spindle, the second motor 226 drives the tool holder 223 to rotate through the gear 227, and the idle position is turned to the switching port 221. Then the tool is returned. After the tool is returned, the second motor 226 is restarted to drive the tool holder 223 to continue to rotate. The spindle replaces the new tool 11. This setting means that the disc 22 only needs to move twice and the tool holder 223 only needs to rotate twice during the entire replacement process, which greatly shortens the travel path during the entire replacement process and greatly reduces the time spent on replacement.

[0036] The locking mechanism 3 includes several mounting blocks 31. The bottom of each mounting block 31 is fixedly connected to the top of the tool holder 223. The mounting blocks 31 are arranged in a ring on the top of the tool holder 223. An arc-shaped block 311 is fixedly connected to the side of each mounting block 31 that is far apart from each other. Two fixing claws 312 are fixedly connected to the end of each mounting block 31 that is far apart from each other. The two fixing claws 312 are symmetrically arranged.

[0037] The fixed claw 312 has a movable groove 313 inside. The top and bottom of the movable groove 313 are both provided with limit grooves 314. The inner wall of the movable groove 313 is slidably limited and fitted with a clamping block 32. The two clamping blocks 32 are fixedly connected to the side of each other that is close to each other. The top and bottom of the clamping block 32 are fixedly connected with limit blocks 322. The limit blocks 322 are slidably limited and fitted with the limit grooves 314. The inner wall of the movable groove 313 is fixedly connected with two springs 33. The other end of each spring 33 is fixedly connected to the side of the clamping block 32 away from the arc-shaped block 321.

[0038] An annular groove 111 is provided at the center of the outer surface of the tool 11. The first arc block 311 and the two second arc blocks 321 are all arc-shaped and are adapted to the annular groove 111. The first arc block 311 and the two second arc blocks 321 are all made of rubber. When the disc 22 moves to the right, the spindle tool 11 contacts the inclined surface of the clamping block 32 and squeezes it into the moving groove 313, which drives the spring 33 to compress. When the annular groove 111 of the tool 11 contacts the first arc block 311, the moving disc 22 stops, the spring 33 returns to its original position and pushes the clamping block 32, so that the second arc block 321 is inserted into the annular groove 111, thus completing the clamping and fixing of the tool 11. This setting can automatically lock the tool 11, which takes less time than the traditional mechanical gripper fixing the tool 11.

[0039] A specific application of this embodiment is as follows: During use, the moving tube 21 is installed in the reserved installation position. When the tool needs to be replaced, the motor 213 is started, driving the bidirectional lead screw 212 to rotate clockwise. The annular moving block 214 will move to the right along with the electric push rod 216 and the fixed disk 217 via the fixed cage 215. The disc 22 moves along with it, and the switching port 221 moves towards the main shaft. Simultaneously, the motor 226 is started, driving the gear 227 to rotate clockwise. Since the gear 227 is meshed with several teeth 225, and the fixed shaft 222 is rotatably connected to the disc 22, the tool holder 223 will rotate counterclockwise. After the tool holder 223 is rotated to the switching port 221, the vacated position is moved. When motor 226 is turned off, the spindle moves synchronously upward as the disc 22 moves, aligning the annular groove 111 on the tool with the free arc block 311. At this time, the disc 22 continues to move to the right, and the tool 11 on the spindle contacts the inclined surfaces on the two clamping blocks 32, squeezing the two clamping blocks 32 and causing them to enter the moving groove 313. At this time, the two springs 33 connected to the clamping blocks 32 are squeezed. When the annular groove 111 contacts the arc block 311, the disc 22 stops moving. At this time, the springs 33 push the clamping blocks 32 to reset through their own elasticity. The arc blocks 321 on the two clamping blocks 32 will enter the annular groove 111 to clamp and fix the tool 11. At this time, the spindle unlocks the tool 11 and moves upward away.

[0040] Then, start motor 226 to drive tool holder 223 to continue rotating counterclockwise. When the tool 11 to be replaced moves to the bottom of the spindle, turn off motor 226. At this time, the spindle moves down, so that the top of tool 11 enters the spindle taper hole and is clamped. The replacement is then completed. Start motor 213 to drive bidirectional lead screw 212 to rotate counterclockwise. The annular moving block 214 drives electric push rod 216 and disc 22 to move to the left together. This setting allows disc 22 to move only twice and tool holder 223 to rotate only twice during the entire replacement process, which greatly shortens the travel path during the entire replacement process and significantly reduces the time spent on replacement.
