Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC milling cutter technology, specifically to a tool inspection device for vertical machining centers. Background Technology
[0002] The core advantages of vertical machining centers are high precision, high automation, and high cutting efficiency, but these characteristics also place stringent requirements on the condition of the tools, and tool wear is a key factor affecting their performance.
[0003] An adjustable tool wear detection device for CNC machine tools is disclosed in the existing patent publication number CN112484637B, which includes a mounting device, a clamping device and a detection mechanism. The mounting device includes a mounting plate, and side plates are connected to both sides of the surface of the mounting plate. The laser rangefinder is disposed on one side of the connecting plate.
[0004] In the above technical solution, the milling cutter can be detected by a laser rangefinder through the clamping device and detection mechanism. However, the clamping device is fixed by manually turning the threaded rods on the four sides. This clamping method is time-consuming and labor-intensive, and it is difficult to ensure that the central axis of the threaded rod is aligned with the rotation center during clamping, which is prone to errors. Moreover, the overall operation is cumbersome.
[0005] Therefore, it is essential to design a tool inspection device for vertical machining centers that is both practical and easy to clamp. Utility Model Content
[0006] The purpose of this invention is to provide a tool inspection device for vertical machining centers to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a tool inspection device for a vertical machining center, comprising a clamping part and a limiting part, wherein the clamping part includes a plurality of clamping blocks and a tooling disc for limiting the linear displacement of the clamping blocks, the lower ends of the plurality of clamping blocks are provided with planar threads, the lower end of the tooling disc is rotatably connected to a rotatable threaded ring, and the upper side of the threaded ring is provided with a planar thread adapted to the clamping blocks;
[0008] The limiting part is located on the outside of the tooling tray and is in contact with the tooling tray.
[0009] According to the above technical solution, a worktable is rotatably connected to the outer side of the tooling tray, and a detection mechanism is provided on the upper side of the worktable.
[0010] According to the above technical solution, the tooling disc includes an outer ring, a central disc is fixedly connected to the middle side of the outer ring, the central disc is provided with a plurality of sliding grooves, guide blocks are fixedly connected between the sliding grooves, and the lower end of the clamping block is slidably engaged with the guide block.
[0011] According to the above technical solution, extension plates are fixedly connected to both sides of the lower end of the clamping block, and a threaded plate is provided between a pair of extension plates, with the planar thread provided on the lower side of the threaded plate.
[0012] According to the above technical solution, the limiting part includes an electromagnet block, and the tooling plate is made of magnetic metal.
[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0014] The tooling disc is fixed by limiting the limiting part. At this time, the threaded ring rotates relative to it, driving several clamping blocks to move and clamp the tool body on the middle side. The clamping work of the tool body can be completed. The operation is simple and convenient, and the positioning accuracy and clamping stability are strong.
[0015] The limiting part releases the restriction on the tooling disc, allowing it to rotate. At this point, the threaded ring has completed driving the clamping block, which has clamped the tool body. Under the self-locking action of the threaded connection, the threaded ring and the tooling disc are fixed together. If the threaded ring continues to rotate, it can directly drive the tooling disc to rotate synchronously, thus rotating the tool body and enabling wear detection. The limiting part restricts the tool body, allowing the threaded ring to drive the clamping block to clamp the tool body and further drive its rotation for detection. No additional drive components or corresponding structures are needed, resulting in a simple structure and reduced costs. Attached Figure Description

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-6 The present invention provides a technical solution: a tool inspection device for a vertical machining center, including a clamping part and a limiting part. The clamping part includes a plurality of clamping blocks 101 and a tooling plate 2 that limits the linear displacement of the clamping blocks 101. The lower ends of the plurality of clamping blocks 101 are provided with planar threads. The lower end of the tooling plate 2 is rotatably connected to a rotatable threaded ring 3. The upper side of the threaded ring 3 is provided with a planar thread that is adapted to the clamping blocks 101.
[0027] The limiting part is located on the outside of the tooling plate 2 and is in contact with the tooling plate 2.
[0028] When it is necessary to clamp the tool body 6, it is placed between several clamping blocks 101. The contact surfaces of the clamping blocks 101 and the threaded ring 3 are all provided with planar threads. When the threaded ring 3 rotates relative to the clamping blocks 101, and under the limiting and guiding action of the tooling plate 2, the clamping blocks 101 can be driven to move synchronously through the planar threads (planar threads are existing technology in the field of clamping tooling). Specifically, in the initial state, the limiting part restricts the tooling plate 2 and fixes it. At this time, the threaded ring 3 rotates relative to it, driving several clamping blocks 101 to move and clamp the tool body 6 in the middle, thus completing the clamping work of the tool body 6. The operation is simple and convenient, and the positioning accuracy and clamping stability are strong.
[0029] Next, when inspection is required, the tool body 6 needs to be driven to rotate. At this time, the limiting part releases the restriction on the tooling plate 2, making the tooling plate 2 rotatable. Since the threaded ring 3 has completed the drive of the clamping block 101, the clamping block 101 has clamped the tool body 6. Under the self-locking action of the threaded connection, the threaded ring 3 and the tooling plate 2 are fixed together. When the threaded ring 3 continues to rotate, it can directly drive the tooling plate 2 to rotate synchronously, which can make the tool body 6 rotate and perform wear inspection. In other words, through the limiting part, the threaded ring 3 drives the clamping block 101 to clamp the tool body 6 and can further drive it to rotate for inspection. There is no need to set up additional drive components and corresponding structures, which simplifies the structure and reduces costs.
[0030] The tooling tray 2 is rotatably connected to the worktable 1, and the upper side of the worktable 1 is provided with a detection mechanism 5.
[0031] Preferably, the detection mechanism 5 includes, but is not limited to, a laser rangefinder, which is positioned directly above the rotating tool body 6 to perform wear detection. The detection principle of the laser rangefinder is existing technology, so it will not be described in detail here.
[0032] The tooling tray 2 includes an outer ring 201, a central tray 202 is fixedly connected to the middle side of the outer ring 201, a number of sliding grooves 203 are opened through the central tray 202, and guide blocks 204 are fixedly connected between the sliding grooves 203. The lower end of the clamping block 101 is slidably engaged with the guide block 204.
[0033] Preferably, an outer ring 201 is set to rotate in the middle of the worktable 1, and a lower base 301 is fixedly connected to the lower end of the worktable 1. A rotating disk 302 is rotatably connected to the upper side of the lower base 301. The upper end of the rotating disk 302 is connected to the threaded ring 3. The rotating disk 302 is rotatably connected to the lower end of the outer ring 201. The rotating disk 302 is driven by a motor 303 to drive the threaded ring 3 to rotate, thereby driving the clamping block 101. The clamping block 101 moves along the guide block 204 for guidance.
[0034] An extension plate 102 is fixedly connected to both sides of the lower end of the clamping block 101, and a threaded plate 103 is provided between a pair of extension plates 102, with a planar thread on the lower side of the threaded plate 103.
[0035] Preferably, extension plates 102 are provided at both ends of the clamping block 101, passing through the slide groove 203 and extending to the lower end of the guide block 204. A planar thread is provided on the lower side of the threaded plate 103, and the threaded ring 3 is adapted to the thread of the threaded plate 103, thereby driving the clamping block 101 to move along the guide block 204.
[0036] The limiting part includes an electromagnet block 4, and the tooling plate 2 is made of magnetic metal.
[0037] Preferably, when it is necessary to limit the tooling plate 2, the electromagnet block 4 set inside the worktable 1 is energized to attract the tooling plate 2, so that the tooling plate 2 can be fixed. At this time, the threaded ring 3 can drive the clamping block 101 to clamp the tool body 6. When it is necessary to drive the tool body 6 to rotate, the electromagnet block 4 is de-energized, and the tooling plate 2 can be released from the restriction and rotate synchronously under the drive of the threaded ring 3.
[0038] Optionally, when it is necessary to limit the tooling disc 2, a threaded plate 103 is slidably engaged with a pair of extension plates 102. One end of the extension plate 102 has a square groove, and a spring is installed in the square groove. Limiting blocks 7 are fixedly connected to both ends of the threaded plate 103. A clamping plate 8 is fixedly extended from one end of the threaded plate 103. The clamping plate 8 passes through the outer ring 201 and is slidably engaged with it. A slot 9 adapted to the clamping plate 8 is opened on the inner side of the worktable 1. In the initial state, the clamping block 101 is in the unfolded state. At this time, the clamping plate 8 is also inserted into the slot 9, thereby limiting the tooling disc 2 and preventing it from rotating. At this time, the threaded ring 3 drives the clamping block 101 to move until the tool body 6 is clamped. At this time, part of the clamping plate 8 is still in the slot 9 (e.g., Figure 5 As shown), at this time, since the clamping block 101 clamps the tool body 6, it cannot continue to move. An adaptation groove 10 is provided at the lower end of the tooling plate 2 to facilitate the threaded plate 103 to continue to move towards the center. The spring is compressed, so that the clamping plate 8 is completely moved out of the clamping groove 9. At this time, the limit of the tooling plate 2 can be released, and the tooling plate 2 and the tool body 6 can be directly driven to rotate. In other words, the limiting part does not require additional driving components or additional energy consumption, and can automatically release the limit of the tooling plate 2 and rotate it, which is highly practical.
[0039] When it is necessary to loosen the tool body 6, an arc-shaped groove 11 is provided on the outer side of the outer ring 201, and a square hole is provided on the inner side of the worktable 1. An arc-shaped tooth 12 slides on the inner side. The arc-shaped tooth 12 is adapted to the arc-shaped groove 11 and is locked in one direction. A connecting rod 13 is fixedly connected to one end of the arc-shaped tooth 12. A spring is provided at one end of the connecting rod 13. When the threaded ring 3 drives the tooling disk 2 and the tool body 6 to rotate for inspection (rotation direction as shown in the figure), Figure 6 As shown), at this time, the arc groove 11 moves along the arc surface of the arc tooth 12. When it is necessary to release the tool body 6, the threaded ring 3 reverses, so that the arc groove 11 and the arc tooth 12 are locked together, which can limit the tooling plate 2 to stay still. The clamping plate 8 and the clamping groove 9 are realigned. Then the threaded ring 3 continues to reverse, which can drive the clamping block 101 to reset and move, releasing the tool body 6.
