Abstract
Description
Technical Field
[0001] This utility model relates to the field of wireless five-way tool setting instrument technology, specifically a wireless five-way tool setting instrument with a protective structure. Background Technology
[0002] A wireless five-directional tool setter is a high-precision tool setting device for CNC machine tools (such as machining centers and milling machines). It is mainly used for quickly and accurately measuring the length and diameter of tools and for detecting tool breakage. Its core features are simplified operation and improved measurement efficiency through wireless transmission technology and multi-directional triggering mechanisms.
[0003] In existing technologies, wireless five-axis tool setters are typically fixedly installed on the worktable of CNC machine tools. The usage process is as follows: when inspecting a tool, the tool is moved to the tool setter position by operating the device for measurement. After the measurement is completed, the tool returns to the machining position. However, in non-inspection states, the tool setter is exposed to the machining environment for a long time. Metal chips, dust, or oil mist generated during machining can easily adhere to the contact surface of the probe, which may lead to a decrease in the sensitivity of the trigger signal or misjudgment, affecting the measurement accuracy. If, due to program errors or operational mistakes, the tool or workpiece is accidentally moved to the tool setter position during non-inspection periods, it may directly impact the probe or the main structure, causing mechanical damage or even functional failure. Utility Model Content
[0004] The purpose of this invention is to provide a wireless five-way tool setter with a protective structure, which solves the problem that existing tool setters are exposed to the machining environment for a long time when not in a detection state.
[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 wireless five-directional tool setting device with a protective structure, comprising a tool setting device body, a protective structure at the lower end of the tool setting device body, the protective structure including a protective shell, side plates installed at both ends of the protective shell, a fixing component between the two side plates, two sets of lifting components inside the protective shell, a protective plate at the upper end of each of the two sets of lifting components, a sliding groove on the upper surface of the protective shell, the two protective plates slidably connected inside the sliding groove, a placement plate between the two sets of lifting components, and the tool setting device body mounted on the upper surface of the placement plate.
[0007] Furthermore, the lifting assembly includes a first rotating shaft, which is rotatably connected between two side plates. A first connecting rod, a sector gear, and a spur gear are fixedly installed on the outer surface of the first rotating shaft. The other end of the first connecting rod is hinged to the outer surface of the protective plate. A rack is provided at one end of the spur gear, and a placement plate is installed on the upper surface of the rack. The rack meshes with the spur gear.
[0008] Furthermore, a second rotating shaft is rotatably connected between the two side plates, and a second connecting rod is fixedly installed on the outer surface of the second rotating shaft. The other end of the second connecting rod is hinged to the outer surface of the protective plate.
[0009] Furthermore, a support frame and a motor are installed at the inner bottom of the protective shell. A worm gear is installed at the output end of the motor via a coupling. One end of the worm gear is installed on the lower surface of the support frame. A driven gear is installed at one end of the first rotating shaft in one of the lifting components. The worm gear is meshed with the driven gear.
[0010] Furthermore, the sector gears in the two adjacent lifting components mesh with each other.
[0011] Furthermore, one end of one of the side plates is provided with a first connecting plate, and the other end of the other side plate is provided with a second connecting plate. A groove is formed on one side of the second connecting plate, and one end of the first connecting plate is fitted into the inside of the groove. A placement groove is formed on one side of the first connecting plate, and an installation groove is formed on the inner surface of the placement groove. The fixing component includes two levers, both of which are slidably connected inside the installation groove. A spring is fitted between the two levers, and a limit block is installed on the other end of each of the two levers. A limit groove is formed on the inner surface of the inner wall of the groove, and one end of the limit block penetrates the first connecting plate and is fitted into the inside of the limit groove.
[0012] Furthermore, a baffle is installed inside the placement slot, and an opening is provided on the outer surface of the baffle. One end of each of the two levers is slidably connected inside the opening, and a limiting plate is hinged to one side of the opening, with the limiting plate located between the two levers.
[0013] This utility model has the following beneficial effects:
[0014] (1) This utility model drives the spur gear to rotate through the first rotating shaft, so that the rack meshing with it moves in the vertical direction. The rack pushes the tool setter body to rise or fall through the placement plate. When the first rotating shaft rotates, the first connecting rod fixed on it rotates with the shaft and pushes the protective plate to slide along the axis of the protective shell slide groove through the hinge point. The second connecting rod on the second rotating shaft rotates synchronously, so that the protective plate can be smoothly opened or closed, forming a cover or exposure of the tool setter body. When the protective plate is closed, it cooperates with the protective shell and the side plate to effectively protect the tool setter body and avoid the tool setter body from being exposed to the processing environment for a long time and being affected by the outside world.
[0015] (2) By pressing the two paddles inward, the two paddles slide towards the middle of the mounting groove, while the spring is gradually compressed. When the paddles move, they drive the limiting block out of the limiting groove of the groove, releasing the lock on the first connecting plate and the second connecting plate. When the limiting block is completely out of the limiting groove, the mechanical constraint between the first connecting plate and the second connecting plate is released. The operator can pull the side plate horizontally along the groove direction to make the first connecting plate slide out of the groove of the second connecting plate. When the connecting part of the two side plates is completely separated, the two side plates can be separated from the protective shell to achieve the effect of easy disassembly, exposing the internal lifting component and the tool setting device body, which makes it easier for the operator to inspect the lifting component and the tool setting device body.
[0016] 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

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 Figures 1-5 As shown, this utility model is a wireless five-way tool setting device with a protective structure, including a tool setting device body 1. The lower end of the tool setting device body 1 is provided with a protective structure, which includes a protective shell 2. Both ends of the protective shell 2 are equipped with side plates 3. A fixing component 4 is provided between the two side plates 3. Two sets of lifting components 5 are provided inside the protective shell 2. A protective plate 6 is provided at the upper end of each of the two sets of lifting components 5. A sliding groove is opened on the upper surface of the protective shell 2. The two protective plates 6 are slidably connected inside the sliding groove. A placement plate 7 is provided between the two sets of lifting components 5. The tool setting device body 1 is installed on the upper surface of the placement plate 7.
[0027] One of the side panels 3 has an opening on its outer surface;
[0028] By using the protective shell 2, side plates 3 and protective plate 6 together, the knife device body 1 can be well protected during non-detection periods. The lifting component 5 can control the lifting of the knife device body 1. During the lifting of the knife device body 1, the protective plate 6 can be opened and closed at the same time. The fixing component 4 can be set to quickly separate the two side plates 3, which makes it easier for staff to repair the parts inside the protective shell 2.
[0029] The lifting assembly 5 includes a first rotating shaft 501, which is rotatably connected between two side plates 3. A first connecting rod 502, a sector gear 503, and a spur gear 504 are fixedly installed on the outer surface of the first rotating shaft 501. The other end of the first connecting rod 502 is hinged to the outer surface of the protective plate 6. A rack 505 is provided at one end of the spur gear 504. A placement plate 7 is installed on the upper surface of the rack 505. The rack 505 is meshed with the spur gear 504.
[0030] A second rotating shaft 506 is rotatably connected between the two side plates 3. A second connecting rod 507 is fixedly installed on the outer surface of the second rotating shaft 506. The other end of the second connecting rod 507 is hinged to the outer surface of the protective plate 6.
[0031] The inner bottom of the protective shell 2 is equipped with a support frame 8 and a motor 9. The output end of the motor 9 is equipped with a worm gear 10 through a coupling. One end of the worm gear 10 is installed on the lower surface of the support frame 8. One end of the first rotating shaft 501 in one of the lifting components 5 is equipped with a driven gear 11. The worm gear 10 is meshed with the driven gear 11.
[0032] The sector gears 503 in the two adjacent lifting components 5 mesh with each other;
[0033] The first rotating shaft 501 drives the spur gear 504 to rotate, causing the rack 505 meshing with it to move in the vertical direction. The rack 505 pushes the tool setter body 1 to rise or fall through the placement plate 7. When the first rotating shaft 501 rotates, the first connecting rod 502 fixed on it rotates with the shaft, pushing the protective plate 6 to slide along the axis of the slide groove of the protective shell 2 through the hinge point. The second connecting rod 507 on the second rotating shaft 506 rotates synchronously, so that the protective plate 6 can be smoothly opened or closed, forming a cover or exposure of the tool setter body 1. When the protective plate 6 is closed, it works with the protective shell 2 and the side plate 3 to effectively protect the tool setter body 1 and prevent the tool setter body 1 from being exposed to the processing environment for a long time and being affected by the outside world.
[0034] One side plate 3 has a first connecting plate 301 at one end and a second connecting plate 302 at the other end. A groove is provided on one side of the second connecting plate 302. One end of the first connecting plate 301 is fitted inside the groove. A placement groove is provided on one side of the first connecting plate 301. An installation groove 303 is provided on the inner surface of the placement groove. The fixing component 4 includes two levers 401. Both levers 401 are slidably connected inside the installation groove 303. A spring 402 is fitted between the two levers 401. A limit block 403 is installed on the other end of each of the two levers 401. A limit groove is provided on the inner surface of the inner wall of the groove. One end of the limit block 403 passes through the first connecting plate 301 and is fitted inside the limit groove.
[0035] A baffle 404 is installed inside the placement slot. An opening is provided on the outer surface of the baffle 404. One end of each of the two levers 401 is slidably connected inside the opening. A limiting plate 405 is hinged to one side of the opening and is located between the two levers 401.
[0036] By pressing the two levers 401 inward, the two levers 401 slide towards the middle of the mounting groove 303, while the spring 402 is gradually compressed. When the levers 401 move, they drive the limiting block 403 out of the limiting groove, releasing the lock on the first connecting plate 301 and the second connecting plate 302. When the limiting block 403 is completely out of the limiting groove, the mechanical constraint between the first connecting plate 301 and the second connecting plate 302 is released. The operator can pull the side plate 3 horizontally along the groove direction to make the first connecting plate 301 slide out of the groove of the second connecting plate 302. When the connecting part of the two side plates 3 is completely separated, the two side plates 3 can be separated from the protective shell 2, achieving the effect of easy disassembly, exposing the internal lifting assembly 5 and the tool setting device body 1, which makes it easier for the operator to inspect the lifting assembly 5 and the tool setting device body 1.
[0037] In use, first install the protective shell 2 on the upper surface of the workbench, then install the tool setter body 1 on the placement plate 7. Next, lead the data cable from one end of the tool setter body 1 through the opening in the side plate 3 and insert it into the corresponding device's connector. Start the motor 9, causing its output end to drive the worm gear 10 to rotate via the coupling. Since the worm gear 10 meshes with the driven gear 11, the driven gear 11 drives the first rotating shaft 501 to rotate. The first rotating shaft 501 then drives the spur gear 504 to rotate, causing the rack 505 meshing with it to move vertically. The tool setting device body 1 is pushed up by the placement plate 7. When the first rotating shaft 501 rotates, the first connecting rod 502 fixed on it rotates with the shaft and pushes the protective plate 6 to slide outward along the axis of the slide groove of the protective shell 2 through the hinge point. The second connecting rod 507 on the second rotating shaft 506 rotates synchronously, so that the opening on the protective shell 2 is gradually exposed. During the rising process, the tool setting device body 1 extends completely from the internal space of the protective shell 2 to the outside. The protective plate 6 slides completely to both sides of the slide groove and no longer covers the tool setting device body 1. At this time, the tool can be detected by the tool setting device body 1.
[0038] After the tool inspection is completed, the motor 9 is started in reverse. The motor 9 rotates in reverse, and the output end of the motor 9 drives the worm gear 10 to rotate through the coupling. Since the worm gear 10 meshes with the driven gear 11, the driven gear 11 drives the first rotating shaft 501 to rotate in reverse. When the first rotating shaft 501 rotates in reverse, the spur gear 504 on it drives the meshing rack 505 to move downward in the vertical direction. The rack 505 drives the tool setting instrument body 1 to descend synchronously through the placement plate 7 and gradually retract into the protective shell 2. When the first rotating shaft 501 rotates in reverse, the first connecting rod 502 rotates in reverse at the same time with the first rotating shaft 501. Through the hinge point, it pulls the protective plate 6 to slide towards the center along the slide groove of the protective shell 2. The second connecting rod 507 on the second rotating shaft 506 rotates in reverse synchronously, so that the protective plate 6 closes smoothly and covers the opening. At this time, the tool setting instrument body 1 completely returns to the interior of the protective shell 2. In the absence of inspection, it can effectively protect the tool setting instrument body 1 and avoid the tool setting instrument body 1 from being exposed to the machining environment for a long time and being affected by the external environment.
[0039] By moving the limiting plate 405 outward, it rotates axially outward around the hinge point with the baffle 404. After rotating 90°, the limiting plate 405 releases its restriction on the two side blocks 401. Then, by pressing the two side blocks 401 inward, they slide towards the center of the mounting groove 303, while simultaneously compressing the spring 402. As the blocks 401 move, they cause the limiting block 403 to disengage from the limiting groove, releasing the restriction on the first connecting plate 301 and the second connecting plate 302. When the limiting block 403 is completely removed from the limiting groove, the mechanical constraint between the first connecting plate 301 and the second connecting plate 302 is released. The operator can pull the side plate 3 horizontally along the groove direction to make the first connecting plate 301 slide out of the groove of the second connecting plate 302. When the connecting part of the two side plates 3 is completely separated, the two side plates 3 can be separated from the protective shell 2 to achieve the effect of easy disassembly, exposing the internal lifting component 5 and the tool setting device body 1, which makes it easier for the operator to inspect the lifting component 5 and the tool setting device body 1.
