The collet jaws enclose each other to form a central hole, and the collet jaws are connected by an elastic layer. The material of the elastic layer is nano-rubber. Compared with the prior art, in the present invention, an elastic layer made of nano-rubber is arranged between the collet jaws. Due to the good elasticity and excellent mechanical properties of nano-rubber, etc., the present invention has high stability in the repeated clamping accuracy and higher accuracy. In addition, the structure of the invention is short and the overall weight of the tooling is light, so that the overall structure of the bushing connecting the main shaft is also greatly shortened, thereby saving energy and raw materials, reducing the load on the main shaft, increasing the stroke of the machine tool, and having simple loading and unloading, and further extending the service life of the collet, greatly improving the economic benefits and work efficiency.

[0003] The prior art measures the inner diameter, outer diameter, length and other dimensions of the collet manually by using traditional mechanical measuring tools such as micrometers, vernier calipers, depth gauges, etc. Although it is simple and direct, it is easy to produce errors and has low efficiency. Content of the Utility Model

A size recording plate is threadedly connected through a first threaded section on the outer peripheral wall of the first rotating rod. A scale is engraved on the top of the size recording plate. Two opposite-moving sliding plates are slidably installed through a guide rod on the top of the support frame. An insertion rod is fixedly installed on the top of the sliding plate. A marking pen is installed on the bottom of the sliding plate by interference fit with a clamping plate. Two opposite-moving clamping plates are provided at the positions corresponding to the two insertion rods on the top of the support frame.

[0007] A further technical improvement of the present utility model lies in that: the structure for promoting the two sliding plates to move towards each other includes a second rotating rod rotatably installed at a position in the middle between the two sliding plates on one side of the support frame. A winding rope is fixedly installed between the outer peripheral wall of the second rotating rod and each of the two sliding plates. A compression spring sleeved on the outer peripheral wall of the guide rail rod is fixedly installed between the opposite sides of the two sliding plates and the support frame, and a tension spring sleeved on the outer peripheral wall of the guide rail rod is fixedly installed between the opposite sides of the two sliding plates and the support frame.

[0008] Further, the size recording board is made of tempered glass, has a certain strength and is not easily damaged, and the stains and dyes on its surface are easy to clean, facilitating repeated use.

[0009] Further, the mechanism for promoting the two clamping plates to move towards each other includes L-shaped plates slidably connected through both sides of the top of the support frame. The two L-shaped plates are respectively fixedly connected to the two clamping plates. A third rotating rod is disposed through the two L-shaped plates.

[0019] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation manner, structure, features and their effects of the present utility model as follows.

[0020] Please refer to Figures 1-3 As shown, this embodiment provides a clamping dimension detection device for a chuck, including a base 1. A support frame 2 is fixedly installed on the top of the base 1. A first rotating rod 3 is rotatably installed between the support frame 2 and the base 1. A first threaded section 4 is provided on the outer peripheral wall of the first rotating rod 3. A dimension recording plate 5 is threadedly connected through the first threaded section 4 of the first rotating rod 3. The dimension recording plate 5 is made of tempered glass, which is easy to clean the stains and pigments on its surface while maintaining a certain hardness. A scale 6 is engraved on the top of the dimension recording plate 5. Slide plates 8 are slidably installed through guide rail rods 7 on both sides of the top of the support frame 2. An insert rod 9 is fixedly installed on the top of the slide plate 8. A clamping plate 10 is fixedly installed on the bottom of the slide plate 8. A marker pen 11 is installed in the clamping plate 10 by interference fit, which is convenient for removing the marker pen 11 and installing a new one when the pigment of the marker pen 11 is used up. The pen tips of the two marker pens 11 are aligned vertically with the corresponding insert rods 9 respectively;

[0021] When the dimension recording plate 5 is rotated clockwise on the first threaded section 4, the dimension recording plate 5 will move upward along the guide rail rod 7 and approach the bottom of the marker pen 11. When the dimension recording plate 5 is rotated counterclockwise, the opposite is true. By the above steps, the distance between the marker pen 11 and the dimension recording plate 5 can be adjusted. When the top of the dimension recording plate 5 abuts against the bottoms of the two marker pens 11, rotating the first rotating rod 3 will drive the dimension recording plate 5 to rotate at the bottoms of the two marker pens 11, so that the marker pen 11 draws a circle with the first rotating rod 3 as the axis and the distance between the first rotating rod 3 and the marker pen 11 as the radius. When the first rotating rod 3 rotates half a turn, the two marker pens 11 just draw a complete circle on the dimension recording plate 5. Observing the distance between the circumference and the scale 6 on the first rotating rod 3, the radius of the circumference can be obtained, and then multiplying by two can obtain the size between the two marker pens 11;

[0022] Compression springs 12 sleeved on the outer peripheral wall of the guide rail rod 7 are fixedly installed between the opposite sides of the two sliding plates 8 and the support frame 2, and tension springs 13 sleeved on the outer peripheral wall of the guide rail rod 7 are fixedly installed between the opposite sides of the two sliding plates 8 and the support frame 2. A second rotating rod 14 is rotatably installed at a position in the middle of the two sliding plates 8 on one side of the support frame 2. Winding ropes 15 are fixedly installed between the outer peripheral wall of the second rotating rod 14 and the two sliding plates 8 at the same time;

[0023] When the second rotating rod 14 is rotated in the clockwise direction, the second rotating rod 14 will wind the two winding ropes 15 with the same length, so that the two winding ropes 15 drive the two sliding plates 8 to approach each other by the same distance respectively. At this time, the two sliding plates 8 will simultaneously compress the compression springs 12 and simultaneously stretch the tension springs 13, so that the two compression springs 12 and the two tension springs 13 are in the same stress state. When the torsion on the second rotating rod 14 is released, the stress states of the two compression springs 12 and the two tension springs 13 are released, and then they rebound to the natural state to drive the two sliding plates 8 to move away from each other by the same distance. Through the above steps, the distance between the two sliding plates 8 can be adjusted, and at the same time, the distance between the two inserting rods 9 and the two marking pens 11 can be adjusted. By adjusting the distance between the two inserting rods 9, the two inserting rods 9 can be inserted into the clamping surface of the elastic chuck, and the two inserting rods 9 can be abutted against the clamping surface of the elastic chuck, so as to obtain the size of the clamping dimension of the elastic chuck;

[0024] Two symmetrically arranged L-shaped plates 16 are slidably installed through the top of the support frame 2. Clamping plates 17 are fixedly installed on the opposite sides of the two L-shaped plates 16. The clamping surface of the clamping plate 17 is adapted to the outer peripheral wall of the elastic chuck, and the clamping surface of the clamping plate 17 is made of rubber material to avoid generating large stress due to rigid contact with the elastic chuck and causing damage to the elastic chuck. A third rotating rod 18 is arranged through the two L-shaped plates 16. A driving motor for driving the third rotating rod 18 to rotate is installed on the support frame 2. The two ends of the third rotating rod 18 are respectively rotatably connected to the two sides of the support frame 2. Two second thread sections 19 with opposite helix directions are arranged on the outer peripheral wall of the third rotating rod 18. The two L-shaped plates 16 are respectively threadedly connected to the third rotating rod 18 through the two second thread sections 19 with opposite helix directions;

[0025] When the third rotating rod 18 is rotated in the clockwise direction, the third rotating rod 18 will drive the two L-shaped plates 16 to approach each other through the two second thread sections 19 with opposite helix directions, so that the two L-shaped plates 16 drive the two clamping plates 17 to approach each other, thereby reducing the distance between the two clamping plates 17. When the third rotating rod 18 is rotated in the counterclockwise direction, the situation is opposite. Through the above steps, the distance between the two clamping plates 17 can be adjusted. Furthermore, when the clamping surface of the elastic chuck is installed on the two inserting rods 9, by reducing the distance between the two clamping plates 17, the outer peripheral wall of the elastic chuck can be squeezed, so as to reduce the clamping dimension of the elastic chuck.

[0026] When the utility model is in use, first rotate the second rotating rod 14 to adjust the distance between the two inserting rods 9 to a size suitable for inserting into the clamping surface of the elastic chuck. Then, release the torsion on the second rotating rod 14. At this time, under the resilience of the two compression springs 12 and the tension spring 13, the two inserting rods 9 move away from each other at the same distance until they abut against the clamping surfaces on both sides of the elastic chuck. Then, move the dimension recording plate 5 upward so that the top of the dimension recording plate 5 abuts against the bottoms of the two marking pens 11. Then, make the first rotating rod 3 drive the dimension recording plate 5 to rotate at the bottoms of the two marking pens 11. When the first rotating rod 3 rotates half a circle, the two marking pens 11 just draw a complete circle on the dimension recording plate 5. At this time, the size of the drawn circle is the maximum clamping size of the elastic chuck being detected. Then, rotate the third rotating rod 18 in the clockwise direction until the third rotating rod 18 drives the two clamping plates 17 through the two L-shaped plates 16 to squeeze the elastic chuck into the smallest clamping state. Then, drive the dimension recording plate 5 to rotate at the bottoms of the two marking pens 11 through the first rotating rod 3, so as to obtain the minimum clamping size of the elastic chuck being detected. Then, observe the distance between the two circles through the scale 6 to obtain the clamping range of the measured elastic chuck.

[0027] The above is only a preferred embodiment of the utility model, and it does not impose any form of limitation on the utility model. Although the utility model has been disclosed above with the preferred embodiment, it is not intended to limit the utility model. Any person skilled in the art can make some changes or modifications to it as equivalent embodiments with equivalent changes within the scope of the technical solution of the utility model. However, as long as it does not depart from the content of the technical solution of the utility model, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model still fall within the scope of the technical solution of the utility model.
