Description

Technical Field

[0001] The utility model belongs to the technical field of cylinder detection, in particular to a flat cylinder straightness detection device. Background Art

[0002] Cylinders are used in air conditioner compressors. Due to the special structure of the cylinder and the need to drill a mounting hole in the center of the cylinder, the mounting hole needs to be perpendicular to the cylinder surface. If professional instruments are used to detect the verticality during batch processing, it will take too much time and the cost of detection is also high. Therefore, a cylinder inspection fixture that can quickly and cost-effectively detect the verticality of the cylinder is needed. The shell of a turbine, a rotary piston engine, etc. is usually also called a "cylinder". A cylinder refers to a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The application areas of cylinders: printing (tension control), semiconductors (spot welding machines, chip grinding), automation control, robots, etc.

[0003] A Chinese patent with publication number CN105588500A discloses an air-conditioning cylinder verticality detection device, which belongs to the field of air-conditioning cylinder inspection tools, and includes an operating handle and a detection scale. The detection scale is an "L" shape formed by two detection arms perpendicular to each other. The operating handle is fixed at the bottom of one detection arm of the detection scale. The detection rod is fixed at the center position of the end of the operating handle. The detection rod is parallel to one detection arm of the detection scale, and the other detection arm is perpendicular.

[0004] In the current existing technology, a cylinder refers to a cylindrical metal part that guides a piston to perform linear reciprocating motion in the cylinder. A flat cylinder adopts a flat design, has a compact structure, occupies a small space, and is suitable for occasions where space is limited. However, existing flat cylinders are relatively thin, and the place where they need to be installed is relatively narrow and compact. If the flat cylinder is bent, it cannot be effectively installed during installation due to the curvature of the cylinder. It is necessary to perform surface curvature detection on the flat cylinder, but it is inconvenient to observe the curvature on the surface of the cylinder with the naked eye, and some detection equipment cannot fix the equipment, resulting in inconvenient detection efficiency.

[0005] To this end, the utility model provides a flat cylinder straightness detection device. Utility Model Content

The fitted electric shock strip will be energized after contacting the surface of the electric shock strip. An alarm is fixedly installed on the top edge of the slider. When the electric shock strip is energized, a light will appear on the surface of the alarm. Only when the alarm lights up, it indicates that the curvature on the surface of the flat cylinder is too large and is difficult to install.

[0013] Preferably, the inner surface of the clamping positioning strip is movably overlapped on the inner surface of the clamping groove, and a flat cylinder is movably sleeved on the inner surface of the overlapping detection sleeve, thereby limiting the position of the flat cylinder to avoid deviation in curvature detection due to instability of the equipment when the flat cylinder detects curvature.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. A flat cylinder straightness detection device described in the utility model overlaps the slider on the top surface of the flat cylinder, and at the same time cooperates with the gravity of the drop rod to fall and overlap on the surface of the flat cylinder, cooperates with the slider to slide on the inner surface of the swing bar, and when the drop rod slides on the surface of the flat cylinder, the drop rod will move up and down due to the depression or bulge on the surface of the flat cylinder. If the curvature on the surface of the flat cylinder has too large deviation, the fitting electric shock strip on the top surface of the drop rod will fluctuate up and down inside the electric shock strip and contact with the surface of the electric shock strip. After the fitting electric shock strip contacts with the surface of the electric shock strip, it will be energized. When the electric shock strip is energized, a light will appear on the surface of the alarm. Only when the alarm lights up, it means that the curvature on the surface of the flat cylinder is too large and it is not easy to install. The swing bar is extended and retracted by the telescopic rod, and different positions on the surface of the flat cylinder can be checked.
