The two ends of the first positive and negative threaded screw 23 pass through the upper part of the inner side wall of the base 11 respectively. A first sliding groove 24 is opened on both sides of the center of the upper surface of the base 11. A first clamping arm 25 is slidably connected to the inner side wall of the two first sliding grooves 24.

The tops of the two second clamping arms 32 are fixedly connected to the second clamping blocks 34. The adjacent sides of the two second clamping blocks 34 are respectively attached to the lower part of the front and rear surfaces of the workpiece 28 to be inspected. By having the two second clamping blocks 34 simultaneously and tightly attached to the front and rear surfaces of the workpiece 28 to be inspected, the workpiece 28 to be inspected is limited and fixed, preventing the workpiece 28 to be inspected from moving back and forth.
[0033] In one embodiment, specifically: a limiting plate 35 is fixedly connected to the upper part of the inner sidewall of the U-shaped frame 12, and a limiting hole 36 is opened at the center of the upper surface of the limiting plate 35. The outer sidewall of the mounting cylinder 15 is slidably connected to the inner sidewall of the limiting hole 36. By sliding the outer sidewall of the mounting cylinder 15 along the limiting hole 36, the stability of the movement of the mounting cylinder 15 is increased.
[0034] In one embodiment, specifically: a limiting ring 37 is fixedly connected to the top of the outer side wall of the mounting cylinder 15, and the lower surface of the limiting ring 37 is attached to the upper surface of the limiting plate 35 near the outer side of the limiting hole 36. The limiting ring 37 limits the mounting cylinder 15 to the extreme position of downward movement.
[0035] In one embodiment, specifically: a first limiting groove 38 is provided in the middle of the inner front wall and inner rear wall of the first sliding groove 24; a first limiting block 39 is fixedly connected to the lower part of the front surface and rear surface of the first clamping arm 25; the outer side wall of the first limiting block 39 is slidably connected to the inner side wall of the first limiting groove 38; a second limiting groove 40 is provided in the middle of both sides of the inner side wall of the second sliding groove 31; a second limiting block 41 is fixedly connected to the lower part of both sides of the second clamping arm 32; the outer side wall of the second limiting block 41 is slidably connected to the inner side wall of the second limiting groove 40; by the sliding of the first limiting block 39 on the first clamping arm 25 inside the first sliding groove 24, the stability of the movement of the first clamping arm 25 is increased; by the sliding of the second limiting block 41 on the second clamping arm 32 inside the second limiting groove 40, the stability of the movement of the second clamping arm 32 is increased.
[0036] In one embodiment, specifically: a first knob 42 is fixedly connected to one side of the first threaded screw 23, and a second knob 43 is fixedly connected to the front surface of the second threaded screw 30. The first knob 42 and the second knob 43 facilitate the rotation of the first threaded screw 23 and the second threaded screw 30.
[0037] In one embodiment, specifically: a touch screen 44 is provided on the upper surface of the controller 20; wherein, the touch screen 44 provides a convenient interactive bridge between the operator and the semi-automatic inspection fixture, through which the operator can intuitively input various inspection commands, such as setting the lifting stroke of the electric cylinder 14, the speed of the reduction motor 16, and other inspection parameters; moreover, the data generated during the inspection process, such as the size and shape data collected by the inspection head 19, after being processed by the controller 20, will be displayed on the touch screen 44 in real time, allowing the operator to grasp the inspection status in a timely manner and judge whether the workpiece is qualified.
[0038] In operation, the workpiece 28 to be inspected is placed at the center of the upper surface of the base 11. By rotating the first knob 42, the first threaded screw 23 rotates within the first rotating hole 22. Since the threads at both ends of the first threaded screw 23 rotate in opposite directions, they engage with the first threaded hole 26, causing the two first clamping arms 25 to slide in opposite directions within the first sliding groove 24. This, in turn, moves the first clamping block 27 until it tightly contacts the lower sides of the workpiece 28, completing the initial horizontal fixation. Then, by rotating the second knob 43, the second threaded screw 30 rotates within the second rotating hole 29. The inner rotation causes the two second clamping arms 32 to slide within the second slide groove 31, and the second clamping block 34 moves accordingly, closely fitting the lower front and rear surfaces of the workpiece 28 to be inspected, achieving all-around stable clamping of the workpiece 28 and ensuring that the workpiece will not shift during the inspection process; through the touch screen 44 on the controller 20, parameters such as the extension stroke and speed of the electric cylinder 14 and the rotation speed of the reduction motor 16 are set according to the inspection requirements of the workpiece 28. These settings are transmitted to the controller 20 to provide instructions for subsequent inspection operations; after the settings are completed, the inspection program is started on the touch screen 44, and the control... When the controller 20 receives the start signal, it sends a command to the electric cylinder 14. The output end of the electric cylinder 14 pushes the mounting cylinder 15 downward along the limiting hole 36. The mounting cylinder 15 drives the reduction motor 16, the detection rod 17, the detection seat 18, and the detection head 19 to descend synchronously until the detection head 19 moves to the detection position in the hole on the workpiece 28 to be inspected. At this time, the controller 20 sends a start command to the reduction motor 16. The reduction motor 16 drives the detection rod 17 to rotate, and the detection seat 18 and the detection head 19 rotate accordingly. During the rotation, the detection head 19 detects the workpiece and transmits the collected data to the controller 20 in real time. 0. The controller 20 analyzes and processes the received detection data, compares it with the preset standard parameters, and determines whether the workpiece 28 to be inspected is qualified. The processing result is displayed intuitively to the operator through the touch screen 44, such as "qualified" or "unqualified", and can further present the specific detection data and deviation value. After the detection is completed, the operator operates on the touch screen 44. The controller 20 controls the electric cylinder 14 to retract, driving the detection component 1 to rise and reset. The operator releases the first knob 42 and the second knob 43, removes the detected workpiece, places a new workpiece 28 to be inspected, and repeats the above steps to carry out the next round of detection.
[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
