Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a CCD visual detection device for an electric guide rail screw. Background Art

[0002] After the electric guide rail screw is processed, it needs to be inspected to check the surface quality and processing accuracy of the screw. CCD visual inspection equipment is often used to perform quality inspection on the processed screw, and the outer wall of the screw is provided with threads.

[0003] In most cases, the lead screw in the mechanical system is right-handed, but in some specific applications, left-handed threads can be used. This situation is usually less common, especially in situations where natural loosening needs to be prevented or special design is required. The diameters at both ends of the electric guide lead screw are generally consistent, which ensures stability and uniformity during installation and operation. When the two types of lead screws are centrally mixed and inspected, it is necessary to clamp the two ends of the lead screw with a fixture. Since the diameters at both ends of the lead screw are consistent, it is not easy to distinguish lead screws with different rotation directions when placing the lead screw. When inspecting lead screws with different thread rotation directions, the detector needs to make corresponding adjustments. If the frequency of alternating placement of lead screws with two rotation directions is too high, it will reduce the working efficiency of the CCD visual inspection equipment. Therefore, it is necessary to inspect lead screws with the same rotation direction in sequence as much as possible to reduce the adjustment time of the detector and improve the inspection efficiency.

[0004] In order to solve the above problems, we proposed a CCD vision inspection device for electric guide screw. Utility Model Content

[0021] The driving mechanism includes a guide column 13 symmetrically fixed to the right side wall of the support plate 2 3. The guide column 13 is horizontally arranged to the right and a limit plate 15 is fixed at the end. A guide plate 14 is slidably sleeved on the two guide columns 13. An avoidance hole corresponding to the slide groove 2 5 is opened in the middle of the guide plate 14. The inner diameter of the avoidance hole is larger than the width of the slide groove 2 5. The inner walls of the bottom ends of the slide groove 1 4 and the slide groove 2 5 are both smoothly arranged for placing the two ends of the screw rod. A spring is sleeved on the guide column 13. The two ends of the spring are fixedly connected to the guide plate 14 and the limit plate 15 respectively. Under the elastic action of the spring, the guide plate 14 is squeezed on the outer wall of the support plate 23, and the right wall of the guide plate 14 is fixedly connected to two fixing plates 16, and the two fixing plates 16 are commonly fixedly connected to a motor 17 located on the right side of the avoidance hole, and the driving end of the motor 17 is horizontally pointed to the center of the avoidance hole, and the driving end of the motor 17 is fixedly connected to an end cover 2 18 located in the avoidance hole, and a rubber pad is arranged in the end cover 18 for squeezing and fixing the end of the screw rod, and the two fixing plates 16 are commonly fixedly connected to a handle 21 located on the outside of the motor 17.

[0022] A vertical guide groove 7 is provided on the support plate 1 2 and the support plate 2 3. A horizontal guide rod 8 is slidably inserted in the two guide grooves 7. A mounting plate is fixedly sleeved on the outer wall of the guide rod 8. The mounting plate is horizontally arranged. A pad 9 is fixed on the upper side of the mounting plate. A plurality of evenly distributed helical teeth are fixedly arranged on the upper wall of the pad 9. The pad 9 has two specifications. One is a pad 9 with forward helical teeth, and the other is a pad 9 with reverse helical teeth. The two pads 9 correspond to screw rods with two thread rotation directions, respectively. Both ends of the mounting plate are fixedly connected with a horizontally arranged connecting plate 10. The two connecting plates 10 are rotationally symmetrical about the center of the mounting plate. Two cylinders 11 corresponding to the two connecting plates 10 are fixedly arranged on the base plate 1. The cylinders 11 are vertically arranged, and the driving ends of the two cylinders 11 are fixedly connected to the corresponding connecting plates 10, respectively.

[0023] A support frame 12 located at the rear side of the pad 9 is fixedly connected to the bottom plate 1 , and a detection mechanism is arranged on the support frame 12 . The detection mechanism includes a support seat 19 fixed to the upper end of the support frame 12 , and a detector 20 is slidably arranged on the support seat 19 .

[0024] The working principle of the utility model is: drive the cylinder 11 to make the guide rod 8 drive the mounting plate and the pad 9 to rise to the top of the guide groove 7, and then pull the motor 17 outward through the handle 21, and at the same time, the guide plate 14 is away from the support plate 23, select a wire, and place the two ends of the screw rod in the slide groove 1 4 and the slide groove 2 5. When the thread of the screw rod matches the gap between the helical teeth on the pad 9, the end located in the slide groove 1 4 will fall into the end cover 1 6, and the end cover 1 6 will limit its axial position. At this time, the other end of the screw rod extends outward from the slide groove 2 5 and aligns with the avoidance hole. After slowly loosening the handle 21, under the action of the spring, the guide plate 14 drives the motor 17 to move left, and the end cover 2 18 will be set on the end of the screw rod and squeeze the end of the screw rod through the rubber pad. Then, by adjusting the movement of the detector 20 and the rotation of the screw rod, the screw rod is fully tested;

[0025] When the thread of the screw rod does not match the gap between the helical teeth on the pad 9, the screw rod thread is supported by the top of the helical teeth and cannot completely fall into the end cover 6, and then fixation and detection cannot be achieved. The helical teeth are made of plastic material to reduce wear on the screw rod.

[0026] This method can make screws with the same thread rotation direction be inspected in sequence in mixed inspection. When inspecting screws with another thread rotation direction, it is sufficient to install a pad 9 with reverse helical teeth, which is convenient for improving the efficiency of mixed inspection of screws.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
