Description

Technical Field

[0001] The invention relates to mechanical equipment related to quality inspection of cables after processing, and in particular to online detection equipment for cable appearance defects. Background Art

[0002] Cable insulation or sheath surface defects such as bulges, pits, exposed wires, peeling and uneven scratches are easy to appear during production. If the defects cannot be directly detected and eliminated during production, it will directly affect the product quality. The quality of cable products will be transferred to customers later, resulting in quality complaints and causing great losses to the manufacturer. The existing traditional sheath detection mainly uses laser detection, but laser detection has many defects, such as no defective images, inability to make secondary judgments, and easy detection blind spots.

[0003] In order to meet the needs of appearance inspection, the utility model patent with application number CN202022245734.X proposes a cable outer surface detection device. The cable outer surface detection device, by installing a lead plate, a concave lead plate, an alarm device and a forward and reverse motor, effectively solves the problems of complicated operation when the cable has different outer diameters, low efficiency of switching back and forth, and untimely discovery of defective products causing product outflow and production losses.

[0004] Although the above technology has preliminarily solved the problem of whether detection is possible, there are still two problems during detection: first, the inaccurate installation position of the cable will lead to deviations in the detection results; second, the specific location of the defect cannot be fed back in time during the detection, which is not convenient for subsequent repair work. Summary of the invention

[0005] In order to solve the above two unresolved problems, the present invention proposes an online detection equipment for cable appearance defects.

[0006] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

The main detection device is used to detect whether there are defects on the outer surface of the cable, the auxiliary positioning installation device assists manual installation of the cable accurately, and the two three-jaw chucks are used to fix the two ends of the cable respectively. During installation, the cable needs to pass through the two semicircular ring sleeves.

[0008] The left part of the main counter is respectively equipped with an I-type hydraulic cylinder and a guide rail; the guide rail is provided with a slidable I-type bearing seat, and the I-type bearing seat is connected to the I-type hydraulic cylinder. That is, the I-type bearing seat can slide horizontally.

[0009] A type II bearing seat is fixedly installed on the right part of the main counter, and the type I bearing seat and the type II bearing seat are fixedly installed on the lower ends of the two three-jaw chucks respectively. Through the above structure, the distance between the two three-jaw chucks can be adjusted to adapt to the length of the cable.

[0010] The main counter is provided with a lateral groove; the auxiliary positioning installation device also includes a handle frame that can slide forward and backward along the lateral groove and a type II hydraulic cylinder connected to the handle frame. The auxiliary positioning installation device can ensure that the cable is clamped at the center axis position of the three-jaw chuck on the right side during installation. The handle frame can slide backward to avoid interference during detection.

[0011] The II-type hydraulic cylinder is installed on the main counter, and two semicircular ring sleeves are installed on the upper rear part of the handle frame.

[0012] The detection main drive assembly includes an I-type motor and a long rod installed in the auxiliary cabinet frame; the I-type motor is connected to a ball screw, and the ball screw is matched with an offset plate slidably connected to the long rod. That is, the offset plate can slide horizontally.

[0013] The deflection plate is connected to a circular main winding platform, on which a detection radial control member and a detection circumferential control member are respectively installed; the detection radial control member includes a surrounding seat that slides with the main winding platform, and the detection circumferential control member includes an annular gear ring that is fixedly connected to the surrounding seat. The central axis of the main winding platform and the annular gear ring is also set to be colinear with the central axis of the two three-jaw chucks. The detection circumferential control member is used to control the circumferential movement of the surrounding seat.

[0014] A circular groove is formed on the arc surface of the main winding platform, and the surrounding seat is slidably mounted on the circular groove. This structure ensures that the surrounding seat can move in a circular motion.

[0015] The detection radial control member also includes a cylinder mounted on the surrounding seat, a detection extension rod connected to the cylinder, and a detection needle mounted on the detection extension rod; the surrounding seat is provided with a through hole for the detection extension rod to pass through. That is, driven by the cylinder, the detection needle can move radially to abut against the cable surface for subsequent detection.

[0016] The detection annular control component also includes a spur gear meshing with the annular gear ring, a type II motor connected to the spur gear, and a motor frame for fixing the type II motor, and the motor frame is fixedly installed on the main winding platform. The annular gear ring is controlled to rotate through gear transmission to realize the annular movement of the surrounding seat.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention uses a semicircular ring sleeve to coaxially position the cable during installation, ensuring accurate clamping position, thereby improving detection accuracy.

[0019] 2. The present invention can control the detection needle to make full contact with the entire outer surface of the cable, and provide feedback through the runout value, so as to find the defect position in time and facilitate repair.

[0020] 3. The entire detection process of the present invention is completed by automated equipment except for clamping, and the operation is relatively convenient.

[0021] 4. The detection process of the present invention can control the detection needle to perform detection in a non-stop mode to meet the actual demand for non-stop production and processing of cables. BRIEF DESCRIPTION OF THE DRAWINGS

The auxiliary positioning and installation device can ensure that the cable is clamped at the center axis position of the three-jaw chuck 2 on the right side during installation. The handle frame 7 can slide backward to avoid interference during detection.

[0036] The II type hydraulic cylinder 8 is installed on the main counter 1, and the two semicircular ring sleeves 3 are installed on the rear upper part of the handle frame 7.

[0037] The detection main drive assembly includes an I-type motor 11 and a long rod 12 installed in the auxiliary cabinet frame 9; the I-type motor 11 is connected to a ball screw 13, and the ball screw 13 is matched with an offset plate 14 slidably connected to the long rod 12.
