Description

Technical Field

[0001] The invention belongs to the technical field of clamping and picking devices for detection, and in particular relates to a single-open fixed picking mechanism. Background Art

[0002] In the process of using inspection tools to inspect products, the products need to be positioned and fixed before the inspection operation can be carried out. The existing single-open structure requires the movable end to move closer to the fixed end to achieve positioning and fixation. This results in the inability to inspect some inspected parts that need to be stretched open to achieve positioning and fixation. That is, the existing hand-tightened single-open mechanism cannot meet the positioning and fixation requirements of this type of product. Therefore, a single-open fixed pickup mechanism is needed to solve the positioning and fixation of the product to be inspected.

[0003] In addition, after the product is positioned and fixed, it is often necessary to lift the inspected product from the clamping mechanism by hand after the single-open fixed pickup mechanism is released in order to pick up the inspected product. In many cases, the inspected product will be hung or hooked by the positioning part of the clamping mechanism, making it difficult to quickly and smoothly remove the inspected product. Therefore, a clamping mechanism that can facilitate the removal of the product is also needed to solve this problem. The functional requirements are met by improving the mechanism, and the above problems can now be solved through this structure. Summary of the invention

[0004] The purpose of the present invention is to provide a single-open fixed pickup mechanism, which is intended to solve the problem in the background technology that the existing hand-tightened single-open mechanism cannot meet the needs of being stretched open to achieve positioning and fixing of the inspected parts, and that after the inspection is completed, the inspected product will be hung or hooked by the positioning part of the clamping mechanism, making it difficult to quickly and smoothly remove the inspected product.

[0005] To solve the above technical problems, the purpose of the present invention is achieved as follows:

[0007] Base;

[0008] The fixing part comprises a first positioning part, wherein the first positioning part is fixedly arranged at the upper end of the fixing part, and the fixing part is fixedly arranged at the base;

[0009] The movable part includes a second positioning part, the movable part is arranged opposite to the fixed part, the second positioning part is located at the upper end of the movable part, the lower end of the movable part is movably connected to the base, and the first positioning part and the second positioning part extend outward along opposite back surfaces of the fixed part and the movable part respectively;

[0010] The adjusting mechanism can drive the movable part to swing around the axis of the hinge between the movable part and the base.

[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the tops of the first positioning portion and the second positioning portion are both inclined surfaces, the inclined surfaces are inclined from the top of the second positioning portion to the top of the first positioning portion, and the inclined surfaces of the tops of the first positioning portion and the second positioning portion are coplanar.

[0012] On the basis of the above solution and as a preferred solution of the above solution: the lower end of the movable part is hinged to the base.

[0024] A single-open fixed pickup mechanism, comprising

[0025] Base 1;

[0026] The fixing part 2 comprises a first positioning part 21, wherein the first positioning part 21 is fixedly arranged at the upper end of the fixing part 1, and the fixing part 2 is fixedly arranged at the base 1;

[0027] The movable part 3 includes a second positioning part 31, and the movable part 3 is arranged opposite to the fixed part 2. The second positioning part 31 is located at the upper end of the movable part 3, and the lower end of the movable part 3 is movably connected to the base 1. The first positioning part 21 and the second positioning part 31 extend outward along the opposite back sides of the fixed part 2 and the movable part 3 respectively, and form a first hook part a and a second hook part b after extension. When positioning and fixing the fixed edge of the product to be detected, the first hook part a and the second hook part b fix and limit the product to be detected; preferably, the lower end of the movable part 3 is hinged to the base 1 at the hinge shaft 6.

[0028] Specifically, in this embodiment, the tops of the first positioning portion 21 and the second positioning portion 31 are preferably the first inclined surface 211 and the second inclined surface 311, respectively, and the first inclined surface 211 and the second inclined surface 311 are inclined from the top of the second positioning portion 31 to the top of the first positioning portion 21, and the first inclined surface 211 and the second inclined surface 311 are coplanar when the inspected product is positioned and fixed.

[0029] The adjusting mechanism 4 can drive the movable part 3 to swing around the axis of the hinge shaft 6 between the movable part 3 and the base 1 .

[0030] Specifically, in this release method, it is preferred that the base 1 is also extended with a support 11, and the movable part 3 is located between the support 11 and the fixed part 1; the adjustment mechanism 4 includes an adjusting screw 41, and the support 11 is provided with a horizontal through hole 111, and the adjusting screw 41 passes through the through hole 111 and is threadedly connected with the movable part 3, and the inner diameter of the through hole 111 is larger than the outer diameter of the adjusting screw 41, and a limit block 5 is sleeved on the adjusting screw 41, and the limit block 5 is located at one end of the through hole 111 away from the movable part 3, and after the adjusting screw 41 and the movable part 3 are tightened, the limit block 5 contacts the end face of the through hole 111. The principle of the adjustment mechanism in this embodiment driving the movable part 3 to swing is as follows: assuming that the adjustment screw 41 is rotated clockwise in the direction of tightening the thread of the adjustment screw and the movable part, when rotating clockwise, the adjustment screw is restricted to move to the right due to the limiting effect of the limit block 5, so that the adjustment screw will pull the movable part 3 to the left (the observer faces the Figure 1 , the direction of the observer's left hand is left), then the movable part 3 will rotate leftward around the axis of the hinge shaft 6, so that the second limiting part 31 will move away from the first limiting part 21 to hold the fixed end pressing part of the product to be inspected tightly, and the first hook-shaped part a and the second hook-shaped part b will clamp and limit the fixed end pressing part of the product to be inspected, thereby realizing the positioning and fixation of the product to be inspected.

[0031] However, since the movable part is threadedly connected to the adjusting screw 41, when the movable part 3 rotates around the hinge shaft 6, the adjusting screw 41 will also swing accordingly. Therefore, in order to simplify the structure of the entire device, a countersunk hole 112 is provided on the support 11 in the present application. The countersunk hole 112 is located at the end of the through hole 111 away from the movable part 3, and the limit block 5 is located in the countersunk hole 112. The inner diameter of the countersunk hole 112 is larger than the outer diameter of the limit block 5. Therefore, by selecting a large countersunk hole 112 and a large inner diameter of the through hole, sufficient movable space is provided for the adjusting screw 41 to meet the swinging requirement of the movable part for clamping or releasing the clamping part of the fixed part of the product to be inspected.

[0032] In order to further facilitate the rotation of the adjusting screw 41, in the present embodiment, a rotating portion 43 is preferably provided on the end of the adjusting screw 41 away from the movable portion 3, and the rotating portion 43 and the adjusting screw 41 are connected by a connecting rod 42, and the three are coaxially arranged, so that when the adjusting screw 41 needs to be rotated, the rotating portion 43 can be held or clamped by hand or other tools, and then a rotational force is applied to the rotating portion 43 to drive the adjusting screw 41 to rotate.

[0033] The specific working principle is:

[0034] The first step is to combine Figure 1, when the adjusting screw 41 is loosened, the fixed end pressing part of the detected product is placed on the opposite side of the first positioning part 21 and the second positioning part 31, so as to be opposite to the first inclined surface 211 and the second inclined surface 311. At this time, the fixed end pressing part of the detected product is partially in contact with the first inclined surface 211 and the second inclined surface 311;

[0035] In the second step, the adjusting screw 41 is rotated to drive the movable end 3 to rotate around the hinge shaft 6 in a direction away from the fixed part 2 under the action of the thread transmission, so that the first positioning part 21 and the second positioning part 31 tighten the fixed end pressing part, and at the same time, the first hook part a and the second hook part b hook the fixed end pressing part to limit it to prevent it from falling out;

[0036] The third step is to combine Figure 2 , the adjusting screw 41 is rotated in the opposite direction to drive the movable end 3 to rotate around the hinge shaft 6 towards the fixed part 2 under the action of the threaded transmission, thereby loosening the clamping part of the fixed end. At the same time, when the movable end 3 rotates around the hinge shaft 6 towards the fixed part 2, the second inclined surface 311 flips upward, thereby lifting the clamping part of the fixed end of the inspected product upward, and the second hook-shaped part b flips outward to release the hooking state. At this time, the inspected product can be easily removed, making it convenient and quick to remove.

[0037] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
