Description

Technical Field

[0001] The utility model relates to the technical field of detection sampling, in particular to a sampling mechanism for high-precision parts detection. Background Art

[0002] In the field of mechanics, high-precision parts generally refer to parts that have very high requirements on size, shape, surface quality, etc., such as precision bearings, gears, guide rails and guide parts. These parts usually need to maintain a high degree of precision during processing and assembly to ensure the performance and reliability of mechanical equipment, so parts need to be inspected and sampled.

[0003] At present, CCD detectors are usually used for non-contact detection and measurement of object surfaces. They have the advantages of high resolution, fast response, and high accuracy. They can be used to detect the shape, size, surface defects, color and other characteristics of objects. They mainly capture the light signal reflected from the surface of the object through the CCD sensor, and then analyze and process the signal through the image processing algorithm to finally obtain the detection result.

[0004] However, when inspecting parts, it is necessary to use connectors to fix the CCD detector on the inspection equipment or the assembly line inspection wall, and then use the CCD detector to inspect them. Since there are a large number of inspected parts and their positions are arranged differently, but the height and position of the CCD detector are fixed, the CCD detector can only inspect a certain part on the conveyor belt, which is not convenient for inspecting multiple parts. The inspection effect is poor, which affects work efficiency and cannot meet production needs. Therefore, it is urgent to design a high-precision sampling mechanism for parts inspection to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the height and position of the CCD detector in the prior art are fixed, resulting in the CCD detector being able to detect only one part on the conveyor belt, being inconvenient to detect multiple parts, resulting in poor detection effect, affecting work efficiency, and failing to meet production needs, and a sampling mechanism for high-precision part detection is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A sampling mechanism for high-precision parts detection comprises a conveyor, to which a sampling box is fixedly connected, and further comprises: a working box fixedly connected in the sampling box, wherein a movable block is slidably connected to the working box, a mounting seat is lifted and lowered on the movable block, a mounting plate is fixedly connected to the mounting seat, an adjustment plate is rotatably connected to the mounting plate, a detector body is fixedly connected to the bottom of the adjustment plate; an electric push rod is fixedly connected to the mounting seat, and the output end of the electric push rod abuts against the outer wall of the adjustment plate.

[0008] In order to facilitate the connection of the adjustment plate, preferably, a connecting shaft is fixedly connected to the mounting plate, and the adjustment plate is rotatably connected to the connecting shaft.

[0009] In order to facilitate limiting the adjustment plate, further, a limiting spring is fixedly connected to the mounting seat, and the other end of the limiting spring is fixedly connected to the adjustment plate.

[0010] In order to improve the limiting effect of the limiting spring, preferably, the limiting spring is symmetrically arranged in two groups.

[0011] In order to facilitate driving and moving the movable block, preferably, a reciprocating screw is rotatably connected in the working box, and the movable block is threadedly connected to the reciprocating screw.

[0012] In order to facilitate the lifting and lowering of the mounting seat, preferably, an electric telescopic rod is fixedly connected to the movable block, and the mounting seat is fixedly connected to the output end of the electric telescopic rod.

[0013] Compared with the prior art, the utility model provides a sampling mechanism for high-precision parts detection, which has the following beneficial effects:

[0014] 1. The sampling mechanism for high-precision parts detection changes the position of the detector body by controlling the switch of the electric push rod, and then can detect multiple parts on the conveyor belt. It can achieve fine-tuning and precise control of the position of the detector body, ensure the accuracy and stability of the detection, improve the detection effect, and improve the work efficiency during detection sampling to meet production needs.

[0015] 2. The sampling mechanism for high-precision parts detection can flexibly change the height and position of the detector body by controlling the position of the movable block and cooperating with the liftable mounting seat to adapt to objects of different sizes and shapes to improve the applicability and flexibility of detection.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model can control the position of the movable block, and cooperate with the liftable mounting seat to change the height and position of the detector body to adapt to objects of different sizes and shapes to improve the applicability and flexibility of the detection. At the same time, it can also achieve fine-tuning and precise control of the position of the detector body, ensure the accuracy and stability of the detection, improve the detection effect, and improve the work efficiency during detection sampling to meet production needs.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Example:

[0025] Reference Figure 1-Figure 4A sampling mechanism for high-precision parts detection includes a conveyor 1, a sampling box 2 is fixedly connected to the conveyor 1, a conveyor belt is also provided on the conveyor 1, and high-precision parts can be transported and moved, a working box 3 is also installed in the sampling box 2, a rotatable reciprocating screw 301 is also installed in the working box 3, and it can be rotated by an external drive machine or motor, a movable block 302 is also threadedly connected to the reciprocating screw 301, and an electric telescopic rod 4 is also fixedly connected to the bottom of the movable block 302.

[0026] In addition, the mounting seat 5 is fixedly connected to the output end of the electric telescopic rod 4, so that it can drive the lifting of the mounting seat 5 by controlling the switch of the electric telescopic rod 4, and can also cooperate with the reciprocating screw rod 301 to move the movable block 302, so that it can drive the electric telescopic rod 4 to move and adjust the displacement in real time. In addition, a light source lamp is installed on the top of the sampling box 2 to illuminate the interior of the sampling box 2.

[0027] In addition, refer to Figure 2 Two groups of symmetrical mounting plates 6 are fixedly connected to the mounting seat 5, a connecting shaft 601 is fixedly connected to the mounting plate 6, and then the adjusting plate 7 is rotatably connected to the connecting shaft 601, and a detector body 8 is fixedly connected to the bottom of the adjusting plate 7. The detector body 8 is a CCD detector, which is usually used for non-contact detection and measurement of the surface of an object. It has the advantages of high resolution, fast response, and high accuracy. It can be used to detect the shape, size, surface defects, color and other characteristics of an object. It mainly captures the light signal reflected from the surface of the object through a CCD sensor, and then analyzes and processes the signal through an image processing algorithm to finally obtain the detection result, and then high-precision parts can be detected and sampled.

[0028] It needs to be explained that two groups of symmetrical limit springs 502 are fixedly connected to the mounting base 5, and the other end of the limit spring 502 is fixedly connected to the adjustment plate 7. An electric push rod 501 is also fixedly connected to the mounting base 5, and the output end of the electric push rod 501 is against the outer wall of the adjustment plate 7. When the shooting angle of the detector body 8 needs to be adjusted, the switch of the electric push rod 501 can be controlled to push the adjustment plate 7 for adjustment. When the detector body 8 needs to be rotated to the left, the electric push rod 501 on the right can be controlled to make its output end push the position of the adjustment plate 7. At this time, the limit spring 502 on the right will be stretched, and the limit spring 502 on the left will be compressed, thereby limiting the adjustment plate 7 to prevent it from shaking.

[0029] Here, by controlling the position of the movable block 302 and cooperating with the liftable mounting seat 5, the height and position of the detector body 8 can be changed, and then the height and position of the detector body 8 can be flexibly changed to adapt to objects of different sizes and shapes to be detected, thereby improving the applicability and flexibility of detection. At the same time, when it is necessary to adjust the shooting angle of the detector body 8, the position of the detector body 8 can be changed by controlling the switch of the electric push rod 501, and then multiple parts on the conveyor belt can be detected, and the position of the detector body 8 can be fine-tuned and precisely controlled to ensure the accuracy and stability of the detection, improve the detection effect, and improve the work efficiency during detection sampling to meet production needs.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
