Description

Technical Field

[0001] This utility model relates to the field of tool measurement technology, specifically to a tool measurement rotary positioning rolling element shaft system structure. Background Technology

[0002] In machining, cutting tools are the core components of machine tools, and their performance directly affects machining quality and efficiency. Since cutting tools will change in size and shape due to wear during use, they need to be measured and inspected regularly to assess the wear condition and ensure machining accuracy. Currently, cutting tool measurement usually adopts laser measurement technology, which requires placing the cutting tool next to the laser measuring instrument and rotating it to obtain comprehensive measurement data.

[0003] However, existing technologies often use manual rotation of the cutting tool. Manual operation cannot precisely control the rotation angle of the cutting tool, resulting in inaccurate positioning during measurement and affecting data reliability. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a tool measurement rotation positioning rolling element shaft system structure. This solves the problem that the prior art often uses manual rotation of the tool, which makes it impossible to accurately control the rotation angle of the tool and leads to inaccurate positioning during the measurement process.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A tool measuring rotary positioning rolling element shaft system structure, comprising:

[0006] The base has a groove formed inside;

[0007] A dial, which is rotatably connected to the outside of the base via a rotating shaft;

[0008] A rotary positioning assembly includes a ring sleeve, floating balls, and multiple grooves. The ring sleeve is fitted over the outside of the base and fixed to the bottom of the dial wheel. The multiple grooves are arranged in a circular array on the outside of the ring sleeve, and the floating balls abut against the outside of the ring sleeve.

[0009] A linkage component is detachably connected to the top of the dial and abuts against the cutter. When the dial rotates, the linkage component drives the cutter to rotate.

[0010] At least two sets of clamping assemblies are disposed on top of the dial wheel to clamp the tool in the base slot.

[0011] The beneficial effects of this utility model are:

[0012] 1) By forming a groove chamber within the base to accommodate the cutting tool, and connecting a dial wheel to the outside of the base via a rotating shaft, along with a rotary positioning assembly, a clamping assembly, and a detachable linkage assembly, precise positioning and stable fixation of the cutting tool are achieved during laser measurement. The linkage assembly is connected to the top of the dial wheel and abuts against the tool shank, rotating synchronously with the dial wheel. Simultaneously, utilizing the ring, floating ball, and groove structure in the rotary positioning assembly, clear positioning feedback is generated through the collision of the ball and groove, allowing the user to accurately perceive the rotation angle of the dial wheel, thereby precisely controlling the rotation position of the cutting tool and improving measurement accuracy. In addition, at least two sets of clamping assemblies clamp the tool shank in the groove chamber, effectively preventing shaking during rotation and ensuring the stability and reliability of the measurement data.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the rotary positioning assembly also includes a support block, a top rod, and an elastic telescopic rod. The support block is fixed to the outside of the base. One end of the top rod passes through the support block and extends to one side of the ring sleeve. One end of the elastic telescopic rod is fixed to the end of the top rod near the ring sleeve. The ball is disposed on the other end of the elastic telescopic rod.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the ball is set at the other end of the elastic telescopic rod, ensuring that the ball remains floating under the elastic action of the elastic telescopic rod. When the groove on the ring rotates to the position of the ball, the ball collides with the side wall of the groove to produce a clear sound, providing clear positioning feedback, so that the user can accurately perceive the rotation angle of the dial.

[0016] Furthermore, the linkage component includes at least one drag block, and at least one of the drag blocks is detachably connected to the top of the dial.

[0017] The beneficial effect of adopting the above-mentioned further solution is that after the tool is placed in the slot chamber, the drag block is inserted into the hole on the outside of the tool holder, and the drag block is fastened to the top of the dial wheel with bolts. As the dial wheel rotates, the tool will rotate synchronously.

[0018] Furthermore, each clamping assembly includes a screw, a spring, a clamping plate, an arc-shaped bayonet, and a movable through hole. One end of the screw is screwed onto the top of the dial wheel, and the spring is sleeved on the outside of the screw.

[0019] Furthermore, the movable through hole is opened on the clamping plate, and the clamping plate is sleeved on the outside of the screw and abuts against the top of the spring through the movable through hole, and the bayonet is opened on one side of the clamping plate.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the screw is screwed into the top of the dial wheel, and the clamp is sleeved on the outside of the screw through the movable through hole and abuts against the top of the spring. When the screw is turned to make it penetrate into the dial wheel, the clamp compresses the spring. At this time, the clamp moves towards the tool holder through the movable through hole, so that the arc-shaped bayonet on the clamp is precisely engaged with the outside of the tool holder. The preload of the spring is used to ensure the stable fixation of the tool holder.

[0021] Furthermore, the inner wall of the base has a receiving groove.

[0022] Furthermore, the inner wall of the base is provided with a bushing that matches the shape of the groove, and multiple rolling elements move inside the bushing.

[0023] The beneficial effects of adopting the above-mentioned further solution are that after the tool is placed into the bushing, the rolling element contacts the tool, which not only transforms the frictional contact into rolling contact, effectively reducing the friction between the side wall of the slot chamber and the tool, and reducing the wear of the tool during the inspection process, but also allows the tool to be located more closely in the slot chamber, reducing the gap between the tool and the side wall of the slot chamber. At the same time, the receiving groove opened in the inner wall of the slot chamber can accommodate the debris attached to the tool, and the debris can fall into the receiving groove through the gap between the bushing and the inner wall of the slot chamber.

Detailed Implementation

[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] In the field of machining, cutting tools are the core components of machine tools, and their performance directly affects machining quality and efficiency. Since cutting tools will change in size and shape due to wear during use, they need to be measured and inspected regularly to assess the wear condition and ensure machining accuracy. Currently, cutting tool measurement usually adopts laser measurement technology, which requires placing the cutting tool next to the laser measuring instrument and rotating it to obtain comprehensive measurement data.

[0033] However, existing technologies often use manual rotation of the cutting tool. Manual operation cannot precisely control the rotation angle of the cutting tool, resulting in inaccurate positioning during measurement and affecting data reliability. To address this issue, the inventor has proposed a cutting tool measurement rotation positioning rolling element shaft system structure.

[0034] The present invention provides the following preferred embodiments.

[0035] like Figures 1-5 As shown, a tool measuring rotary positioning rolling element shaft system structure includes:

[0036] Base 10, with a groove 101 formed inside the base 10;

[0037] The dial 20 is rotatably connected to the outside of the base 10 via a rotating shaft;

[0038] The rotary positioning assembly 40 includes a ring 401, a floating ball 402, and a plurality of grooves 403. The ring 401 is sleeved on the outside of the base 10 and fixed to the bottom of the dial 20. The plurality of grooves 403 are arranged in a ring array on the outside of the ring 401. The floating ball 402 abuts against the outside of the ring 401.

[0039] Linkage component 50 is detachably connected to the top of the dial 20 and abuts against the tool. When the dial 20 rotates, the linkage component 50 drives the tool to rotate.

[0040] At least two sets of clamping assemblies 60 are disposed on the top of the dial 20 for clamping the tool in the slot 101 of the base 10;

[0041] By forming a groove 101 within the base 10 to accommodate the cutting tool, and connecting the dial wheel 20 to the outside of the base 10 via a rotating shaft, along with the rotary positioning assembly 40, the clamping assembly 60, and the detachable linkage assembly 50, precise positioning and stable fixation of the cutting tool are achieved during laser measurement. The linkage assembly 50 is connected to the top of the dial wheel 20 and abuts against the tool shank, rotating synchronously with the rotation of the dial wheel 20. Simultaneously, utilizing the ring 401, floating ball 402, and groove 403 structure in the rotary positioning assembly 40, clear positioning feedback is generated through the collision of the ball 402 and the groove 403, allowing the user to accurately perceive the rotation angle of the dial wheel 20, thereby precisely controlling the rotation position of the cutting tool and improving measurement accuracy. In addition, at least two sets of clamping assemblies 60 clamp the tool shank in the groove 101, effectively preventing shaking during rotation and ensuring the stability and reliability of the measurement data.

[0042] In this embodiment, as Figures 1-5 As shown, the rotary positioning assembly 40 also includes a support block 404, a top rod 405, and an elastic telescopic rod 406. The support block 404 is fixed to the outside of the base 10. One end of the top rod 405 passes through the support block 404 and extends to one side of the ring 401. One end of the elastic telescopic rod 406 is fixed to the end of the top rod 405 near the ring 401. A ball bearing 402 is disposed on the other end of the elastic telescopic rod 406. The ball bearing 402 can be made of steel ball and metal, which is not only durable but also makes it easier to produce a metallic impact sound.

[0043] The ball 402 is located at the other end of the elastic telescopic rod 406, ensuring that the ball 402 remains floating under the elastic action of the elastic telescopic rod 406. When the groove 403 on the ring 401 rotates to the position of the ball 402, the ball 402 collides with the side wall of the groove 403 to produce a clear sound, providing clear positioning feedback, so that the user can accurately perceive the rotation angle of the dial 20.

[0044] In this embodiment, as Figures 1-5 As shown, the linkage component 50 includes at least one drag block, which is detachably connected to the top of the dial wheel 20. After the cutter is placed in the slot chamber 101, the drag block is inserted into the hole on the outside of the cutter handle and is fastened to the top of the dial wheel 20 by bolts. It can rotate synchronously with the rotation of the dial wheel 20, thereby driving the cutter to rotate synchronously.

[0045] In this embodiment, as Figures 1-5As shown, each clamping assembly 60 includes a screw 601, a spring 602, a clamping plate 603, an arc-shaped bayonet 604, and a movable through hole 605 (the movable through hole 605 can be rectangular). One end of the screw 601 is screwed onto the top of the dial wheel 20. The spring 602 is sleeved on the outside of the screw 601. The movable through hole 605 is opened on the clamping plate 603, and the clamping plate 603 is sleeved on the outside of the screw 601 through the movable through hole 605 and abuts against the top of the spring 602. The bayonet 604 is opened on one side of the clamping plate 603.

[0046] The screw 601 is screwed onto the top of the dial wheel 20. The clamp 603 is sleeved on the outside of the screw 601 through the movable through hole 605 and abuts against the top of the spring 602. When the screw 601 is turned so that it goes deeper into the dial wheel 20, the clamp 603 compresses the spring 602. At this time, the clamp 603 moves towards the tool holder through the movable through hole 605, so that the arc-shaped bayonet 604 on the clamp 603 is precisely engaged with the outside of the tool holder. The preload of the spring 602 ensures the stable fixation of the tool holder.

[0047] In this embodiment, as Figures 1-5 As shown, the inner wall of the slot 101 of the base 10 is provided with a receiving groove 30. The inner wall of the slot 101 of the base 10 is provided with a bushing 70 that is adapted to the shape of the slot 101. Multiple rolling elements 80 are movable inside the bushing 70. The rolling elements 80 include, but are not limited to, balls or cylinders. After the tool is placed into the bushing 70, the rolling elements 80 come into contact with the tool. This not only transforms the frictional contact into rolling contact, effectively reducing the friction between the side wall of the slot 101 and the tool, and reducing the wear of the tool during the detection process, but also allows the tool to fit more closely inside the slot 101, reducing the gap between the tool and the side wall of the slot 101. At the same time, the receiving groove 30 on the inner wall of the slot 101 can accommodate the debris attached to the tool. The debris can fall into the receiving groove 30 through the gap between the bushing 70 and the inner wall of the slot 101.

[0048] The specific working process of this utility model is as follows:

[0049] (1) Place the knife

[0050] First, place the bushing 70 in the groove chamber 101, and then place the tool into the bushing 70 so that the rolling element 80 contacts the tool.

[0051] (2) Install linkage components 50

[0052] Insert the drag block into the hole on the outside of the tool holder and secure it to the top of the dial 20 with bolts.

[0053] (3) Limit the cutting tool

[0054] When the screw 601 is turned to penetrate the dial wheel 20, the clamp 603 compresses the spring 602. At this moment, the clamp 603 moves towards the tool holder through the movable through hole 605, so that the arc-shaped latch 604 on the clamp 603 is precisely engaged with the outside of the tool holder. The preload of the spring 602 ensures the stable fixation of the tool holder.

[0055] (4) Rotate the cutting tool

[0056] The user rotates the dial 20 by hand. Due to the action of the drag block on the tool holder, the tool can be rotated. As the dial 20 rotates synchronously with the ring 401, when one of the grooves 403 on the ring 401 rotates to the position of the ball 402, the metal ball 402 collides with the side wall of the groove 403, producing a crisp sound and providing clear positioning feedback, so that the user can accurately perceive the rotation angle of the dial 20.

[0057] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
