However, CMMs have problems such as high equipment cost, complex operation, and low detection efficiency. In addition, CMMs have high requirements for workpiece clamping stability. Improper clamping can easily lead to measurement errors, further affecting the reliability of the detection results.

[0022] 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.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a fixture that can replace a coordinate measuring machine for accurately detecting the position of blind holes, including a base 1; a vertical plate 2 disposed at one end of the base 1; a mounting groove 3 disposed in the middle of the vertical plate 2, the mounting groove 3 being used to mount one end of a blind hole workpiece; a clamping assembly 4 disposed at the other end of the base 1, used to clamp and fix the other end of the blind hole workpiece; an annular rotating seat 5 disposed on the vertical plate 2, located outside the mounting groove 3; a fixed cylinder 6 mounted on the annular rotating seat 5; several through holes 7 disposed, evenly distributed on the side wall of the fixed cylinder 6; the annular rotating seat 5 being used to drive the fixed cylinder 6 and several through holes 7 on the fixed cylinder 6 to rotate; and several sets of blind hole detection components 8 disposed, evenly distributed on the outer wall of the fixed cylinder 6, used to pass through several through holes 7 on the same side. The through hole 7 is used to detect the position of the blind hole. In actual use, one end of the blind hole workpiece to be tested is passed through the fixed cylinder 6 and placed into the mounting groove 3. The other end of the blind hole workpiece is clamped and fixed by the clamping assembly 4. The annular rotating seat 5 drives the fixed cylinder 6 to rotate around the blind hole workpiece. When the blind hole is aligned with the through hole 7, the blind hole detection assembly 8 extends into the blind hole to detect its position. This device replaces the coordinate measuring machine, avoiding the high cost of the coordinate measuring machine. The clamping assembly 4, together with the mounting groove 3, fixes the pipe wall. Through the mechanical transmission of the annular rotating seat 5 and the fixed cylinder 6 with the through hole 7, together with the blind hole detection assembly 8, the blind hole can be quickly detected. The operation is simple and effectively improves the detection efficiency of blind holes.

[0024] Specifically, the blind hole detection assembly 8 includes an electric cylinder 81 mounted on the outer wall of the fixed cylinder 6. The output end of the electric cylinder 81 is provided with a mounting rod 82, which passes through the mounting rod 82 and is provided with several guide rods 83. One end of the guide rod 83 is provided with a detection rod 84 that extends into the through hole 7, and the other end of the guide rod 83 is provided with a baffle 85. A spring 86 is provided on the outer side of the guide rod 83 and between the mounting rod 82 and the detection rod 84. When the blind hole detection assembly 8 performs detection, the electric cylinder 81 is activated to retract, which drives the mounting rod 82, guide rod 83, detection rod 84, and baffle 85 to approach the fixed cylinder 6. When the detection rod 84 comes into contact with the blind hole workpiece, the electric cylinder 81 continues to retract, which drives the mounting rod 82 to continue to approach the fixed cylinder 6. The spring 86 applies pressure to the detection rod 84. When the annular rotating seat 5 drives the detection rod 84 to move to the blind hole, the detection rod 84 extends into the blind hole for position detection under the action of the compression spring. After the detection is completed, the electric cylinder 81 outputs to reset the blind hole detection assembly.

[0025] Specifically, the contact end of the detection rod 84 is provided with a universal ball 87. By providing the universal ball 87, when the end of the detection rod 84 is slidably connected to the surface of the blind hole workpiece through the universal ball 87, friction between the detection rod 84 and the blind hole workpiece is avoided.

[0026] Specifically, the clamping assembly 4 includes a bidirectional threaded rod 41 rotatably mounted on a base 1. A first drive motor 42 is provided on the base 1 to drive the bidirectional threaded rod 41 to rotate. Two sliders 43 are arranged opposite each other on the bidirectional threaded rod 41. A clamping plate 44 is provided on the slider 43. A buffer pad 45 is provided at the clamping end of the clamping plate 44. By setting the buffer pad 45, the problem of workpiece damage caused by the clamping plate 44 clamping the blind hole workpiece is effectively avoided. In use, the first drive motor 42 drives the bidirectional threaded rod 41 to rotate, so that the two sliders 43 drive the two clamping plates 44 to clamp the blind hole workpiece against each other, thereby realizing the clamping and installation of the blind hole workpiece.

[0027] Specifically, the annular rotating seat 5 includes an annular mounting seat 51 rotatably mounted on the vertical plate 2. The vertical plate 2 is provided with a second drive motor 52, and the drive end of the second drive motor 52 is provided with a gear 53. The outer wall of the annular mounting seat 51 is provided with an annular external gear ring 54 that meshes with the gear 53. In use, the second drive motor 52 drives the gear 53 to rotate, and the gear 53, in conjunction with the annular external gear ring 54, drives the annular mounting seat 51 and the fixed cylinder 6 to rotate, so that the blind hole detection component 8 can detect the position of the blind hole.

[0028] Working principle: When this utility model is in operation, one end of the blind hole workpiece to be tested is passed through the fixed cylinder 6 and placed into the mounting groove 3, while the other end is fixed by the clamping assembly 4. The annular rotating seat 5 drives the fixed cylinder 6 to rotate around the workpiece axis, activating the electric cylinder 81. Its output end drives the mounting rod 82 and guide rod 83 to move, so that the detection rod 84 extends into the through hole 7. The universal ball 87 at the end of the detection rod 84 slides in contact with the workpiece surface. When the detection rod 84 is aligned with the blind hole, the spring 86 applies pressure, so that the detection rod 84 is stably extended into the blind hole, and the position of the blind hole is judged to meet the standard.
