[0020] 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. Example

[0021] like Figures 1-3 As shown, a calibration tool includes a tool body and a base 1. The base 1 has a mounting cylinder 2 suitable for mounting and fixing the tool body. The tool body includes a base 3, a cover 4, and a calibration pin 5. The shape of the base 3 is adapted to the inner cavity shape of the mounting cylinder 2. The base 3 is disposed within the mounting cylinder 2 and is detachable. Two clamping members 6 are provided at the upper end of the base 3, with a clamping gap reserved between the two clamping members 6. The calibration pin 5 can be inserted into the clamping gap. The two clamping members 6... The clamping gap compression can clamp the calibration needle 5. The opposite end faces of the two clamping members 6 are provided with expansion and contraction slopes 7. The inside of the cover body 4 is provided with a conical cavity. The cover body 4 is detachably connected to the base body 3. The cover body 4 is also provided with a clearance hole. When the cover body 4 is placed on the base body 3, the calibration needle 5 passes through the clearance hole. The inner end face of the cover body 4 abuts against the expansion and contraction slopes 7 of the two clamping members 6. Under the action of the cover body 4, the two clamping members 6 deform towards the clamping gap and clamp the calibration needle 5.

[0022] The calibration tool in this embodiment has a simple and reasonable structure. The tool body and the base 1 can be separated, and the calibration needle 5 in the tool body can also be easily disassembled and replaced, making it convenient for actual use.

[0023] The opposing end faces of the two clamping parts 6 are provided with limiting grooves 8. The limiting grooves 8 are vertically arranged and the two limiting grooves 8 are directly opposite each other. When the calibration needle 5 is set in the clamping gap, it is located at the limiting groove 8, which not only facilitates the positioning of the calibration needle 5 during installation, but also prevents the calibration needle 5 from tilting.

[0024] Please see Figure 2 and Figure 3 The clamping component 6 is an integral structure and includes a vertical plate and an expansion block. The vertical plate is erected on the base 3, and the expansion block is set on the top of the vertical plate. The gap between the two expansion blocks is the clamping gap, and the end faces of the two expansion blocks that are far apart from each other are the outer end faces. The outer end faces are expansion inclined surfaces 7.

[0025] The expansion and contraction block is a semi-frustum structure. Two expansion and contraction blocks can be joined together to form a frustum. The expansion and contraction inclined surface 7 is a conical surface that adapts to the inner end face of the cover 4 so as to better fit with the cover 4. When the cover 4 is connected to the base 3, the calibration needle 5 can be clamped by squeezing the two expansion and contraction blocks.

[0026] The base 3 is cylindrical, and the cover 4 is threaded to the top of the base 3 for a detachable connection. The outer end faces of the cover 4 and the base 3 are also provided with anti-slip structures 9, which facilitate the rotation of the cover 4. The anti-slip structure 9 includes a plurality of anti-slip grooves or anti-slip protrusions distributed along the circumference of the cover 4.

[0027] In addition to being used in conjunction with the mounting cylinder 2, the base 3 can also be used at the moving end of a robotic arm that needs to be inspected.

[0028] The mounting cylinder 2 is a cylindrical shape that is adapted to the base 3. The mounting cylinder 2 is provided with a fastening screw hole, and a threaded fastener 10 is provided in the fastening screw hole. One end of the threaded fastener 10 is outside the mounting cylinder 2, and the other end can extend into the mounting cylinder 2. After the tool body is installed into the mounting cylinder 2, the threaded fastener 10 is rotated to press against the tool body, thereby fixing the tool body.

[0029] As an optional implementation, a support member is provided within the clamping gap. After the calibration pin 5 is positioned within the clamping gap, its bottom end rests on the support end face of the support member. The outer end face of the base 3 is provided with graduation marks, which are based on the support end face of the support member and distributed along the axial direction of the base 3. When the base 3 is installed into the mounting cylinder 2, the distance between the upper end face of the mounting cylinder 2 and the support end face of the support member can be determined through the graduation marks. Combined with the heights of the mounting cylinder 2, the base 1, and the calibration pin 5, the height position of the end of the calibration pin 5 can be quickly obtained.

[0030] As another optional implementation, the base 1 has at least three screw holes distributed circumferentially. These screw holes are vertically positioned and penetrate the base 1. Each screw hole contains a screw rod, and the bottom end of the screw rod has a support. The base 1 is supported by multiple supports. Rotating the screw rod adjusts the distance between the support and the base 1, thereby adjusting the level of the upper surface of the base 1. The support and screw rod are connected in a flip-type manner using components such as bullseye bearings. When one or more screw rods are rotated and the support height of the base 1 is adjusted, the connection between each support and screw rod adaptively flips to ensure effective support for the base 1. Furthermore, the upper surface of the base 1 is also provided with a level detection structure. Adjusting each screw rod based on the detection results of the level detection structure can adjust the state of the base 1, thereby accurately determining the position of the tip of the calibration needle 5.
