Automatic thickness measuring device for cold-type coating of roller

Abstract

The invention discloses an automatic thickness measuring device for a cold-type coating of a roller. The automatic thickness measuring device comprises a thickness gauge and a feeding mechanism, wherein the feeding mechanism is mainly composed of a cradle mechanism, a telescopic gun barrel and an extensible drive device. The cradle mechanism is a four-rod linkage mechanism formed by hinging a rocking rod, a cradle upper rod and a horizontal fixing rod mutually, the extensible drive device is mainly composed of a pneumatic pushing rod and an air cylinder, and the pneumatic pushing rod is hinged to the rocking rod. The telescopic gun barrel is installed on the cradle upper rod and is driven by a motor A connected with a counter, the front end of the telescopic gun barrel is provided with a small air cylinder and a thickness measuring scale, and the thickness gauge is arranged on the small air cylinder. A cold-type rotating mechanism is arranged at the position corresponding to the front end of the telescopic gun barrel of the feeding mechanism. An encoder is connected onto the cold-type rotating mechanism. The extensible drive device, the motor A, the small air cylinder, the thickness gauge, the cold-type rotating mechanism and the encoder are connected to a computer control system. The automatic thickness measuring device can finish the measurement of thickness and position of the cold-type coating and full-automation control of the coating thickness process.

Description

technical field [0001] The invention relates to a coating parameter measuring device, in particular to a thickness measuring device of a roll cold type coating. Background technique [0002] In the roll cold-forming coating process, a layer of high-temperature-resistant coating needs to be sprayed or coated in the cold-forming inner cavity of the roll. When coating and hanging, not only strict cold-forming temperature is required, but also the thickness of the coating must ensure the thickness of the cold-forming inner wall. unanimous. [0003] In the past process, when measuring the thickness of the coating, the hand-held thickness gauge was used to detect and read the coating thickness. However, since the traditional thickness gauge is pointer type, the force and angle used by the thickness gauge will affect the measurement data. If it is affected, there will be errors in the reading of the pointer, and only the coating thickness at the two ports of the cold mold can be m...

[0003] In the past process, when measuring the thickness of the coating, the hand-held thickness gauge was used to detect and read the coating thickness. However, since the traditional thickness gauge is pointer type, the force and angle used by the thickness gauge will affect the measurement data. If it is affected, there will be errors in the reading of the pointer, and only the coating thickness at the two ports of the cold mold can be measured during measurement, and the middle part of the cold mold cannot be measured. The measured data needs to be filled in b
