Description

Technical Field

[0001] This utility model relates to the field of piston rod detection technology, and more specifically, to an automatic detection device for the electroplated layer of piston rods. Background Technology

[0002] To facilitate the internationalization of products, my country has specific requirements for coating thickness in its export commodities and foreign-related projects. Therefore, coating thickness measurement has become an important part of quality inspection in the processing industry and surface engineering, and is a necessary means for products to achieve superior quality standards.

[0003] With the continuous advancement of technology, especially the introduction of microcomputer technology in recent years, portable chrome plating layer detectors are now widely used to inspect the electroplating layer of piston rods. This represents a step forward towards miniaturization, intelligence, multi-functionality, high precision, and practicality. However, the original portable chrome plating layer detectors suffered from low inspection efficiency, and due to the inability of manual rotation to accurately rotate the workpiece during inspection, inspection errors occurred.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0042] like Figures 1-4 As shown, this utility model provides an automatic detection device for the electroplated layer of a piston rod, comprising:

[0043] Support, drive unit, and two detection sensors 180;

[0044] The bracket includes a base plate 101, a first support plate 102, and a second support plate 103, which are arranged parallel to each other and spaced apart on the upper part of the base plate 101.

[0045] The driving device includes: a first power end 110, a drive shaft 121, and a driven shaft 131. The first power end 110 is detachably disposed on the side of the first support plate 102 away from the second support plate 103. The two ends of the drive shaft 121 are rotatably supported between the first support plate 102 and the second support plate 103 by bearings, and one end of the drive shaft 121 is connected to the first power end 110, so that the first power end 110 can drive the drive shaft 121 to rotate. The two ends of the driven shaft 131 are rotatably supported between the first support plate 102 and the second support plate 103 by bearings, and the driven shaft 131 is arranged parallel to and spaced apart from the drive shaft 121. The workpiece 200 can be placed on the upper part between the drive shaft 121 and the driven shaft 131, and the rotation of the drive shaft 121 drives the rotation of the workpiece 200 and the driven shaft 131.

[0046] In this embodiment, at least two drive wheels 122 are fixedly spaced on the drive shaft 121, and at least two driven wheels 132 are fixedly spaced on the driven shaft 131. The at least two drive wheels 122 and the at least two driven wheels 132 are respectively arranged in a one-to-one correspondence, and there is a gap between the drive wheels 122 and the driven wheels 132 to facilitate the positioning of the workpiece 200.

[0047] A second power end 140 is provided on the bottom plate 101 on the side of the second support plate 103 away from the first support plate 102; a lead screw 151 is rotatably provided between the first support plate 102 and the second support plate 103, and one end of the lead screw 151 is connected to the second power end 140. The lead screw 151 corresponds to the center line of the drive shaft 122 and the driven shaft 131. Two lead screw nuts 152 are fitted on the lead screw 151, and the two lead screw nuts 152 can be far apart from or close to each other.

[0048] Guide rails 161 are symmetrically arranged on both sides of the lead screw 151, and the guide rails 161 are fixed on the base plate 101. Slides 162 are fixed on the two lead screw seats 152 respectively, and the two slides 162 can slide along the guide rails 161.

[0049] Lifting cylinders 170 are fixed on the two slide blocks 162 respectively, so that the pistons of the two lifting cylinders 170 can reciprocate longitudinally. Two detection sensors 180 are fixed on the pistons of the two lifting cylinders 170 respectively, so that the two detection sensors 180 can move away from or close to each other, and can also be lifted.

[0050] Both the first power end 110 and the second power end 140 are servo motors.

[0051] The working process of the automatic detection device for the electroplated layer of the piston rod provided by this utility model is as follows:

[0052] 1. Place the workpiece 200 on the drive wheel 122 and the driven wheel 132. After pressing the start button, the lifting cylinder 170 rises and the detection sensor 180 contacts the lower circumferential surface of the workpiece 200. The thickness of the chromium plating layer at the detection point is measured by the detection sensor 180.

[0053] 2. After one value is detected, the lifting cylinder 170 descends and resets. The first power end 110 drives the drive shaft 121 to rotate 120 degrees, thereby driving the workpiece 200 to rotate 120 degrees. The detection is repeated until the detection of 3 points on the circumference is completed, thereby realizing the detection of the coating thickness at 3 points on the circumference.

[0054] 3. The second power end 140 drives the two wire nuts 152 to move in opposite directions. This adjustment can be used to adjust the detection position of products of different lengths.

[0055] The automatic detection device for the electroplated layer of the piston rod provided by this utility model does not require manual intervention. It drives the drive shaft and driven shaft to rotate through the cylinder and motor, thereby driving the workpiece to rotate automatically. The rotation angle is adjustable, which greatly improves the detection efficiency and accuracy and saves manpower and material resources.

[0056] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
