Description

Technical Field

[0001] This utility model belongs to the field of pump body processing technology, and relates to a tapping mechanism for positioning holes in vacuum pump housings. Background Technology

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container and create a vacuum. When it is working, the rotating rotor compresses the gas in the cylinder, allowing the gas to flow into the interior of the vacuum pump, thereby extracting air from a sealed space and creating a vacuum in the sealed space.

[0003] When machining the outer casing of a vacuum pump, the positioning holes need to be tapped. Currently, tapping is done directly using a tapping machine. However, since the positioning holes on the outer casing have different diameters, different types of tapping drill bits need to be switched. Although the existing tapping drill bits are replaceable, their replacement efficiency is poor, and there is no separate storage structure for tapping drill bits. When replacing them, it is necessary to find the corresponding size tapping rod from inside the external tool box before installation, resulting in poor overall efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a tapping mechanism for positioning holes in a vacuum pump housing, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A vacuum pump housing positioning hole tapping mechanism includes a base, a vertical plate, and a motor. The top of the base is provided with a vertical plate, and the top of the vertical plate is provided with two lifting rods. The top of the lifting rods is provided with a transmission box, and a drill bit holder is provided on one side of the bottom of the transmission box. The bottom of the drill bit holder is connected to a mounting base, and a tapping drill rod is installed inside the mounting base. A storage box is provided on the back of the vertical plate, and a rotating disk is movably installed inside the storage box via a rotating rod. Multiple storage seats are evenly arranged at the bottom of the rotating disk, and each storage seat has a storage cavity inside.

[0007] In the aforementioned vacuum pump housing positioning hole tapping mechanism, the mounting base has an internal mounting groove, and the top of the tapping drill rod is fitted with a fixing seat, which is fixed inside the mounting groove.

[0008] In the aforementioned vacuum pump housing positioning hole tapping mechanism, the outer thread of the mounting base is provided with two positioning rods, the interior of the fixed base has two positioning holes, and one end of the positioning rod is threaded into the interior of the positioning hole.

[0009] In the aforementioned vacuum pump housing positioning hole tapping mechanism, a gear box is provided on the top of the storage box, and a small gear and a large gear are meshed and connected inside the gear box, with the small gear sleeved on the top of the rotating rod.

[0010] In the aforementioned vacuum pump housing positioning hole tapping mechanism, a side groove is provided on the surface of the vertical plate, and a lever is provided inside the side groove, with one end of the lever fixed to the top of the large gear.

[0011] In the aforementioned vacuum pump housing positioning hole tapping mechanism, a motor is installed at the bottom of the transmission box, and a transmission gear is installed inside the transmission box.

[0012] Compared with the prior art, the advantages of the vacuum pump housing positioning hole tapping mechanism of this utility model are:

[0013] This application features a storage box on the back of the vertical plate, containing a rotating disc and multiple storage seats connected to it. The top of the storage box also has a gearbox. When the tapping rod at the bottom of the mounting base needs replacement, the storage box can be opened, and a lever on the surface of the vertical plate can be moved. The lever rotates the large gear, which in turn rotates the small gear, causing the rotating disc to rotate. This allows for switching the storage seat at the bottom of the rotating disc, and the tapping rod of the required size can be retrieved from inside the storage seat. Both storage and retrieval are simple and efficient. During installation, the fixing seat at the top of the tapping rod is inserted into the mounting slot and locked in place by two sets of positioning rods, making installation quite convenient.
