Description

Technical Field

[0001] This utility model relates to the field of automated manufacturing and processing, and more specifically, to a lining grinding device. Background Technology

[0002] After installing the lining on the flow meter product, the end face and chamfer of the flange rubber plate need to be ground to ensure the flatness of the flange rubber plate, thereby ensuring the sealing performance of the flow meter product after installation.

[0003] Currently, the surface of the rubber sheet is manually sanded using an angle grinder, followed by visual inspection with a ruler placed firmly against the surface for any gaps. Because this process is manual, it's impossible to precisely control the grinding head, thus compromising flatness and hindering effective inspection. Furthermore, this process is physically demanding for the operator and poses significant health risks. Utility Model Content

[0033] Preferably, the lining grinding equipment of this utility model embodiment is used to grind the lining of flow meter products.

[0034] In one possible implementation, two or more sets of fixing devices are included, with the dimensions of the fixing base 2 and roller 11 of different fixing devices adapted to the workpieces to be ground of different specifications.

[0035] Different specifications of fixing devices, with different lengths of the fixing base 2 along the first direction, and correspondingly, different lengths of the rollers 11 set on the fixing bases 2 of different specifications. By setting two sets of fixing devices of different specifications, the grinding requirements of workpieces of different specifications can be met.

[0036] In another possible implementation, the fixing device includes a first fixing device and a second fixing device of different specifications; the lining grinding equipment also includes a first track 21, which is disposed between the first fixing device and the second fixing device and is parallel to the fixing base 2 of the first fixing device and the fixing base 2 of the second fixing device, respectively, and the robot is movably mounted on the first track 21.

[0037] Specifically, the robot's base is mounted on the first track 21 via a slider. The slider is connected to a second motor and slides along the first track 21 under the drive of the second motor.
