[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. They are also known as cutting tools. During the production of cutting tools, it is necessary to check their diameter. This is usually done through a testing device.

[0003] According to the authorized patent application No. 202323105419.7, which discloses a coating tool diameter detection device that facilitates chip breaking, existing detection devices embed the bottom end of the tool into the interior of the chassis during tool diameter detection. The clamping plate is clamped to the bottom end of the tool by the elasticity of the compression spring. Therefore, long-term clamping operation can cause deformation of the compression spring, which can weaken the elasticity. This weakens the elasticity of the clamping plate, resulting in loose clamping. When the tool is not clamped securely, it is easy to cause instability during rotation detection. When the tool is unstable, the diameter detection is inaccurate, affecting the tightness of the detection device during tool diameter detection. Therefore, this utility model proposes a tool product diameter accurate detection device. Utility Model Content

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.

[0023] Please see Figures 1 to 5This utility model provides a technical solution: a precision diameter detection device for cutting tools, comprising a detection device body 100, the detection device body 100 including a base plate 101, a vertical plate 106 fixed to the tail end of the upper surface of the base plate 101, a movable adjustment frame 104 provided on the inner side of the vertical plate 106, a diameter detection fiber optic sensor 105 provided inside the movable adjustment frame 104, a chassis 102 mounted at the middle position of the upper surface of the base plate 101 via a rotary motor, the cutting tool being fixed inside the chassis 102, and the top end of the cutting tool... The diameter detection is performed on the surface of the fiber optic sensor 105 corresponding to the diameter detection inside the movable adjustment frame 104. A lead screw 103 rotates at the center of the interior of the upright plate 106. A forward / reverse motor 107 is mounted on the top of the lead screw 103 on the upper surface of the upright plate 106. The lead screw 103 passes through one end of the movable adjustment frame 104 and has a matching thread structure. A detection host 108 is located at the top of the upright plate 106. The detection host 108 is electrically connected to the diameter detection fiber optic sensor 105. The detection device body 100 also includes:

[0024] The convenient clamping mechanism includes clamping components disposed on both sides inside the chassis 102. The bottom end of the clamping component is provided with a limit sliding component, and the side connection of the clamping component is provided with a push adjustment component. When the detection device body 100 is used to detect the diameter of the cutting tool, the convenient clamping mechanism can reinforce and clamp the device for more stable rotation and detection. The device is reinforced and installed for stable and accurate rotation.

[0025] In order to facilitate and stably clamp and inspect the cutting tool product through the clamping assembly, in this embodiment, preferably, the clamping assembly includes an embedding groove 1021 opened inside the chassis 102, and clamping plates 1022 are provided on both sides of the inside of the embedding groove 1021, which can engage the bottom end of the cutting tool inside the embedding groove 1021. The two clamping plates 1022 can be moved to clamp and fix the bottom end of the cutting tool for convenient and accurate inspection.

[0026] To facilitate the stable compression, movement, and reinforcement installation of the clamping plate 1022 using the limiting sliding assembly, in this embodiment, preferably, the limiting sliding assembly includes a limiting sliding groove 1028 formed on one side inside the embedded groove 1021. Limiting sliders 1020 are provided at both ends inside the limiting sliding groove 1028. The ends of the limiting sliders 1020 are fixed to the ends of the clamping plate 1022 by bolts. A spring 1029 is fixed at the connection between the two limiting sliders 1020. When the clamping plate 1022 moves, it drives the limiting sliders 1020 to slide within the limiting sliding groove 1028 for control. After disassembly, the spring 1029 drives the limiting sliders 1020 and the clamping plate 1022 to reset.

[0027] To facilitate the pressing, pushing, clamping, and fixing of the clamping plate 1022 by pushing the adjustment assembly, in this embodiment, preferably, the pushing adjustment assembly includes a limiting groove 1025 located inside the chassis 102 on the side of the embedded groove 1021. A push plate 1027 is limited inside the limiting groove 1025. An electric cylinder 1026 is fixed at the middle position inside the limiting groove 1025. The end of the electric cylinder 1026 is fixed to the push plate 1027 by bolts, which facilitates the electric cylinder 1026 to drive the push plate 1027 to move. A ball bearing 1024 rolls on the side of the end of the push plate 1027. An inclined surface 1023 is formed on the outer side of the clamping plate 1022, and the outer surface of the ball bearing 1024 contacts the surface of the inclined surface 1023. When the push plate 1027 moves, the clamping plate 1022 is smoothly pushed, pressed, and fixed by the ball bearing 1024 contacting the surface of the inclined surface 1023.

[0028] The protection mechanism includes a protective component disposed on the surface of the diameter detection fiber optic sensor 105. The outer surface of the protective component is provided with an elastic locking component, which can protect the surface of the diameter detection fiber optic sensor 105 when the detection device body 100 is not in use, making it less susceptible to external scratches and damage.

[0029] In order to facilitate the surface protection of the diameter detection fiber optic sensor 105 by means of a protective component, and to prevent scratches and damage when not in use, in this embodiment, preferably, the protective component includes a closed groove 1052 opened at the edge of the diameter detection fiber optic sensor 105 inside the movable adjustment frame 104. The closed groove 1052 is threaded with a protective cover 1051, which can be snapped onto the surface of the diameter detection fiber optic sensor 105 for protection when not in use.

[0030] In order to facilitate the snap-fit ​​installation and protection of the protective cover 1051 through the elastic snap-fit ​​assembly, in this embodiment, preferably, the elastic snap-fit ​​assembly includes an annular groove 1054 fixed to the outer surface of the protective cover 1051, and an elastic ring 1053 is provided on the inner surface edge of the closed groove 1052. The annular groove 1054 is elastically snap-fitted into the interior of the elastic ring 1053, so that the elastic ring 1053 can be elastically snapped into the interior of the annular groove 1054 to snap-fit ​​and protect the protective cover 1051 for use.

[0031] The working principle and usage process of this utility model are as follows: When using this tool product diameter precision detection device, firstly, the detection device body 100 is stably placed at the usage position through the bottom end of the base plate 101. After the detection device body 100 is placed, the tool is fixed inside the chassis 102. The top of the tool is located inside the movable adjustment frame 104 corresponding to the surface of the diameter detection fiber optic sensor 105. Then, the rotary motor drives the chassis 102 and the tool to rotate and pass through the diameter detection fiber optic sensor 105 for diameter detection, which is displayed on the surface of the detection host 108. At the same time, the forward and reverse motor 107 is powered on to drive the lead screw 103 to rotate. The rotation of the lead screw 103 moves the movable adjustment frame 104 and the diameter detection fiber optic sensor 105 to different heights on the tool surface for diameter detection at different positions.

[0032] Then, when the main body 100 of the detection device is not used after detection, the end of the protective cover 1051 is directly embedded into the inside of the closed groove 1052. The protective cover 1051 is locked onto the outer surface of the diameter detection fiber optic sensor 105 by the deformation of the annular groove 1054 and the inside of the elastic ring 1053. This protects the diameter detection fiber optic sensor 105 when not in use, making it easier to protect the diameter detection fiber optic sensor 105 from being touched and damaged, thus improving the convenience of protecting the diameter detection fiber optic sensor 105 after the diameter detection of the tool product by the main body 100 of the detection device.

[0033] Finally, when the main body 100 of the testing device is used to fix the tool product, the bottom end of the tool product can be embedded into the inside of the embedding groove 1021. The electric cylinder 1026 moves to drive the push plate 1027 to move within the limiting groove 1025. When the push plate 1027 moves, the end lifting ball 1024 contacts the surface of the inclined body 1023 and pushes the clamping plate 1022 inward. When the clamping plate 1022 is pushed, the bottom end drives the limiting slider 1020 to slide within the limiting slide groove 1028. Thus, the two clamping plates 1022 move stably at the same time to clamp and fix the tool product at the bottom end. The installation is convenient, and the tool product is still stably clamped and fixed for long-term use for rotation diameter detection. During the detection operation, the tool product is stable and the measurement operation is accurate, which improves the stability of the main body 100 of the testing device and the accuracy of the detection when the diameter of the tool product is detected.
