Description

Technical Field

[0001] The utility model relates to the field of dustproof baffles, in particular to a dustproof baffle drilling and fixing device. Background Art

[0002] A dust baffle is a device used to prevent dust, dirt, water vapor, etc. from entering the interior of a device. It is mainly made of soft materials and is attached to the air inlet, air outlet and other places where dust easily accumulates on the device to prevent dust, dirt, water vapor, etc. from entering the interior of the device. Dust baffles are usually used on home appliances such as computers, air conditioners, washing machines and some industrial equipment.

[0003] In the prior art, during the production and processing of dust baffles, in order to facilitate the later installation and fixation of the dust baffles, it is necessary to drill holes on the surface of the dust baffles. During the drilling process, the operator generally presses the dust baffle and drills holes in it with a drill, or places the dust baffle on a table and fixes the dust baffle by installing a pressure plate.

[0004] However, the manual pressing and fixing method is not only laborious, but also easily causes the drilling position to deviate due to the shaking of the drill bit, thereby reducing the processing accuracy. Although the installation of a pressure plate can improve the drilling accuracy, it cannot be quickly fixed or disassembled, thereby reducing the processing efficiency. Utility Model Content

[0005] The utility model aims to provide a dustproof baffle plate drilling and fixing device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dust baffle drilling and fixing device, comprising a processing table, a first fixing plate is arranged on one side of the processing table, a second fixing plate is installed opposite to the first fixing plate, a long connecting rod is arranged on one side of the second fixing plate, a short connecting rod is installed on one side of the long connecting rod, a turntable is installed on one side of the short connecting rod, and a small cylinder is installed on the other side of the short connecting rod.

The first fixed plate and the second fixed plate are rotatably connected between the long pin shaft and the fixed seat, so that the side of the first fixed plate and the second fixed plate close to the processing table rotates toward the upper surface of the processing table, and finally the first fixed plate and the second fixed plate press the dust baffle on the processing table, thereby completing its fixation, which is not only convenient for disassembly and installation, but also improves the processing efficiency, but also avoids the operator from drilling by pressing, thereby improving the drilling accuracy.

[0016] 2. By setting the limit shaft sliding sleeve into the processing table, fastening the first nut on both sides of the middle part of the limit shaft, so that one side of the first nut abuts against the side wall of the processing table, the limit shaft is limited under the limit of the first nut, and then the extension table sliding sleeve is set on the limit shaft, and then fastened to the two ends of the limit shaft by the second nut and one side of the second nut abuts against the side wall of the processing table, thereby completing the assembly of the extension table.
