Detailed Description
In order to facilitate use, the embodiment of the utility model provides a concave detection contour positioning mechanism of a detection tool. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment provides a concave detection contour positioning mechanism of a detection tool, and the integral installation structure of the concave detection contour positioning mechanism is shown in reference to fig. 1 and 2;
as shown in fig. 1 and 2, a plurality of positioning portions 1 are distributed on the checking fixture table along the outline of the workpiece, and the positioning portions 1 are fixed at a certain height by upright posts 2. For positioning the contour edge of the workpiece,
referring to fig. 3, the specific structure of the positioning part is as follows: comprises a first stop block 3, a second stop block 4 and a base 5; as shown in the figure, the first stop block 3 and the second stop block 4 are connected in a sliding groove arranged on the base 5 in a sliding way; the front end part of the first block 3 is provided with a back-off part 8; one side of the rear end of the back-off part is provided with a butt joint surface; the "front end" and "rear end" referred to herein are the left-right direction of the drawing sheet, and specifically, in the application scene, the side of the base facing the workpiece is the "front end".
With continued reference to fig. the front end of the second stop is provided with an abutment surface.
The key points are as follows: the reverse buckling part 8 extends downwards to enable the contact surface to be opposite to the contact surface of the second stop block. When the workpiece clamping device is used, the abutting surface of the reverse buckling part 8 abuts against the inner contour edge of a workpiece, and the abutting surface of the second stop block abuts against the outer contour edge of the workpiece.
In order to further improve the effect, the abutting surface is designed into a shape matched with the profile surface of the workpiece, and meanwhile, the angle formed by the sliding direction of the first stop block 3 and the second stop block 4 and the contact surface of the workpiece is designed to be 90 +/-3 degrees; so that the stress is uniform and the workpiece is prevented from being damaged.
In the continued reference, the device further comprises a limiting part, wherein the limiting part is used for fixing the first stop block 3 and the second stop block 4 in a positioning completion state; referring to fig. 3, the circumferential surfaces of the first stopper 3 and the second stopper 4 are provided with a limit groove and a limit pin. Meanwhile, the base 5 is also provided with a limiting groove, and the limiting groove penetrates into the sliding groove. Taking the second stopper 4 as an example, after positioning is completed, the limit pin 7 is inserted into the limit groove on the base 5 and enters the limit groove on the second stopper 4 to complete fixing.
The same principle is adopted for limiting the first stopper 3, except that the first stopper is a stop block. The arm of force of first dog 3 is longer, so base 5 extends a portion of leaning on towards the direction of back-off portion 8, leans on the portion to be seted up the spacing groove equally, adopts spacer pin 6 to insert wherein spacing first dog 3.
