Description

Technical Field

[0001] The present invention relates to the technical field of machined parts, and particularly to a precision detection device for high-precision machined parts. Background Technique

[0002] Machining accuracy is the degree of conformity between the actual geometric parameters of the machined part surface after machining, including size, shape, and position, and the ideal geometric parameters required by the drawing. For size, the ideal geometric parameter is the average size; for surface geometry, it is an absolute circle, cylinder, plane, cone, and straight line, etc.; for the relative position between surfaces, it is absolute parallelism, perpendicularity, coaxiality, symmetry, etc. The deviation value between the actual geometric parameters of the part and the ideal geometric parameters is called machining error. After some parts are machined, in order to ensure the accuracy of the machined parts, these machined parts need to be detected at this time.

[0003] The existing precision detection of high-precision machined parts has the following deficiencies:

[0004] During the detection process of machined parts, basically the object is directly placed on the top of the machined part for detection. However, if detected in this way, if affected by external forces, the object is likely to have a certain deviation. When such a deviation occurs, the object will deviate from the original detection position, affecting the detection.

[0005] At the same time, during subsequent processing, sometimes in order to ensure the detection accuracy, after one detection, the object needs to be rotated and detected again to avoid detection omissions and affect the detection accuracy of the object. However, if detected in this way, the scheduling of the object needs to be readjusted, thus affecting the detection speed. Summary of the Invention

[0029] As a preferred solution of this embodiment: the clamping assembly consists of a third movable plate 28, a splint 11, a hinged rod 12, a pressure plate 14, a first spring 15, a sliding rod 16 and an outer sleeve 17. A third movable plate 28 is provided on one side of the extension rod 2, and an outer sleeve 17 is provided in the middle of one side of the third movable plate 28. A sliding rod 16 is provided inside the outer sleeve 17, and a first spring 15 is provided on the outside of the sliding rod 16. A pressure plate 14 is provided on one side of the first spring 15.

The hinged rod 12 and the third movable plate 28 are hinged to each other. During use, the object can be quickly fixed. During the fixing process, the stability of the object can be guaranteed, so that the object is always kept in the middle position, which is convenient for the detection of the object and avoids the occurrence of offset during the detection process. At the same time, it can also adapt to various sizes of special-shaped objects, thereby improving the effect of the equipment adapting to the object and ensuring the convenience of detection.

[0030] As a preferred solution of this embodiment: the toggle assembly is composed of a connecting disk 26, a rotating rod 23, a limit frame 24, a hinge block 25 and a second spring 27. A connecting disk 26 is provided on the outer side of the rotating rod 23. Multiple groups of hinge blocks 25 are hinged on the outer side of the connecting disk 26. A second spring 27 is provided on one side of the hinge block 25. The second spring 27 is connected to the connecting disk 26. A limit frame 24 is provided on one side of the hinge block 25. After the object detection is completed and the object is released from fixation, the force generated by the movement of the extension rod 2 can be used to drive the turntable 13 to rotate, and then the position of the object can be replaced in the process of releasing the fixation, thereby saving the time for subsequent replacement, preventing the accuracy of the object from being checked again later, and ensuring the accuracy of the detection.

[0031] As a preferred solution of this embodiment: both ends of one side of the third movable plate 28 and one side of the clamping plate 11 are provided with connecting grooves, and the hinge rod 12 is hinged inside the connecting groove for easy hinge connection.

[0032] As a preferred solution of this embodiment: a through opening is provided on one side of the transverse plate 3, and the extension rod 2 is located inside the through opening, so that the extension rod 2 extends along the transverse plate 3, thereby facilitating connection with the third movable plate 28.

[0033] As a preferred solution of this embodiment: limit blocks are symmetrically provided at both ends of the rotating rod 23, and limit grooves are symmetrically provided at both ends inside the connecting disk 26, and the limit blocks and the limit grooves are adapted to each other. During the rotation of the rotating rod 23, the connecting disk 26 can be driven to rotate, which is convenient for the subsequent movement of the object.

[0034] As a preferred solution of this embodiment: a circular groove is provided on the top of the base 1, and the turntable 13 is located inside the circular groove. A placement groove is provided on the top of the turntable 13 to facilitate the placement of objects, thereby ensuring the stability of the placement.

[0035] As a preferred solution of this embodiment: The hinge block 25 is made of an arc structure. One side of the hinge block 25 is provided with a fixing groove, and the second spring 27 is located inside the fixing groove, so that the push plate 19 can drive the connecting disk 26 to rotate through the hinge block 25 during the moving process, while during the moving process in the opposite direction, it cannot drive the connecting disk 26 to rotate.

[0036] As a preferred solution of this embodiment: The top of the top plate 5 is provided with a top through groove 18, and the output end of the second electric cylinder 7 is located inside the top through groove 18, which is convenient for replacing the position of the detection head 30.

[0037] Example 1, as Figures 1-6 shown, during the detection process, first place the object inside the turntable 13. At this time, start the first electric cylinder 4, and then the first electric cylinder 4 drives the extension rod 2 and the third moving plate 28 to move. During the moving process, the third moving plate 28 drives the second electric cylinder 7, the sliding rod 16, the pressing plate 14 and the clamping plate 11 to move, so that the two pressing plates 14 approach each other, thereby clamping the object. And during the clamping process, the sliding rod 16 moves into the inner sleeve 17. During the moving process, the first spring 15 is compressed, and the pressing plate 14 drives the clamping plate 11 to move, and then the hinge rod 12 pushes the clamping plate 11, so that the clamping plate 11 clamps the outside of the object, thereby fixing the object, ensuring the fixing effect, preventing the object from shifting during the detection process, and at the same time ensuring the stability during the detection process. Then start the driving motor 9. During the starting process, the driving motor 9 drives the lead screw 8 to rotate. Then during the rotation process of the lead screw 8, it drives the moving block 6 to move. During the moving process of the moving block 6, it drives the second electric cylinder 7 and the detection head 30 to move. When the detection head 30 moves to the specified position, use the detection head 30 to detect the object;

[0038] Example 2, as Figures 1-6As shown, after the object detection is completed, the first electric cylinder 4 is started again, and then the two sets of extension rods 2 are driven to move away from each other. During the process of moving away, the extension rods 2 drive the third moving plate 28, the outer sleeve 17, the sliding rod 16 and the pressing plate 14 to move away from each other, thereby releasing the fixed state of the object. During the process of releasing the fixed state, the extension rods 2 drive the connecting plate 10 and the second moving plate 21 to move. During the movement of the second moving plate 21, the first moving plate 20 and the pushing plate 19 are driven to move. At this time, the pushing plate 19 drives the pushing hinge block 25. Under the limiting action of the limiting frame 24, the hinge block 25 no longer flips, so that the hinge block 25 drives the connecting disk 26 and the rotating rod 23 to rotate. During the rotation, the rotating rod 23 drives the turntable 13 to rotate, so that the turntable 13 drives the object to rotate, thereby adjusting the angle of the object. After the adjustment is completed, the object is clamped again. During the clamping process, the pushing plate 19 moves to the hinge block 25 again, and then the pushing plate 19 squeezes the hinge block 25, and the second spring 27 is compressed, thereby driving the hinge block 25 to flip without restricting the connecting disk 26, which is convenient for subsequent detection here.

[0039] Working principle: During the detection process, first place the object inside the turntable 13. At this time, start the first electric cylinder 4, and then the first electric cylinder 4 drives the extension rod 2 and the third moving plate 28 to move. During the movement, the third moving plate 28 drives the second electric cylinder 7, the sliding rod 16, the pressing plate 14 and the clamping plate 11 to move, so that the two pressing plates 14 approach each other, thereby clamping the object. During the clamping process, the sliding rod 16 moves into the inner part of the outer sleeve 17. During the movement, the first spring 15 is compressed, and the pressing plate 14 drives the clamping plate 11 to move. Then the hinge rod 12 pushes the clamping plate 11, so that the clamping plate 11 clamps the outer side of the object, thereby fixing the object, ensuring the fixing effect, preventing the object from shifting during the detection process, and ensuring the stability during the detection process. Then start the driving motor 9. During the startup process, the driving motor 9 drives the lead screw 8 to rotate. Then during the rotation of the lead screw 8, the moving block 6 is driven to move. During the movement of the moving block 6, the second electric cylinder 7 and the detection head 30 are driven to move. When the detection head 30 moves to the specified position, the object is detected by the detection head 30;

[0040] After the object detection is completed, the first electric cylinder 4 is started again, and then the two sets of extension rods 2 are driven to move away from each other. During the process of moving away, the extension rods 2 drive the third moving plate 28, the outer sleeve 17, the sliding rod 16 and the pressing plate 14 to move away from each other, thereby releasing the fixed state of the object. During the process of releasing the fixed state, the extension rods 2 drive the connecting plate 10 and the second moving plate 21 to move. During the movement of the second moving plate 21, the first moving plate 20 and the pushing plate 19 are driven to move. At this time, the pushing plate 19 drives the pushing hinge block 25. The hinge block 25 no longer flips under the limitation of the limiting frame 24, so that the hinge block 25 drives the connecting disk 26 and the rotating rod 23 to rotate. During the rotation, the rotating rod 23 drives the turntable 13 to rotate, so that the turntable 13 drives the object to rotate, thereby adjusting the angle of the object. After the adjustment is completed, the object is clamped again. During the clamping process, the pushing plate 19 moves to the hinge block 25 again, and then the pushing plate 19 squeezes the hinge block 25, and the second spring 27 is compressed, thereby driving the hinge block 25 to flip, and not restricting the connecting disk 26, which is convenient for subsequent detection here.

[0041] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than limiting the protection scope of the present invention. Any simple modification or equivalent replacement of the technical solution of the present invention by those of ordinary skill in the art shall not depart from the essence and scope of the technical solution of the present invention.
