Description

Technical Field

[0001] The present invention relates to the technical field of drilling machines, and particularly relates to a portable drilling machine. Technical Background

[0002] A drilling machine generally refers to machinery and equipment that uses a tool harder and sharper than the target object to leave a cylindrical hole or cavity on the target object by means of rotary cutting or rotary extrusion. It is also known as a drilling rig, a punching machine, a hole-making machine, a through-hole machine, etc. By drilling precision components, the expected effect can be achieved. There are semi-automatic drilling machines and fully automatic drilling machines. With the increase in human resource costs, most enterprises consider fully automatic drilling machines as the development direction.

[0003] When the existing portable drilling machine is performing drilling operations, in order to perform stable drilling operations, external connecting devices are required to fix the drilling machine, which increases the weight of the drilling machine and is inconvenient for storage and use, thereby reducing the convenience of using the drilling machine. Secondly, when the existing portable drilling machine is connected and used, a bolt connection method is mostly used for installation and fixation. Although this method is effective, the installation and disassembly are relatively cumbersome, thereby reducing the effect of using the drilling machine frame. Therefore, there is an urgent need for a new type of portable drilling machine to solve these problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a portable drilling machine to solve the above problems.

[0005] The present invention achieves the above purpose through the following technical solutions:

[0007] Furthermore, the fixing frame is welded to the base, the base is of a cylindrical structure, and the fixing frame is made of high-strength stainless steel.

[0008] By adopting the above technical solution, when in use, through the cooperation of the fixing base and the base, it is convenient for support, connection and installation.

[0009] Furthermore, the Morse taper sleeve is bolted to the housing, and the drill bit is connected to the Morse taper sleeve through a card slot.

[0010] By adopting the above technical solution, the Morse taper sleeve enables the drill bit to be freely installed and fixed. The Morse taper sleeve can replace different types of cutting heads, and at the same time, the drill bit can perform operations such as drilling, precision boring, reaming, tapping, etc.

[0011] Furthermore, the fixing plate is bolted to the housing, and the connecting sleeve is welded to the fixing plate.

[0013] Furthermore, the connecting hole is formed on the connecting sleeve, the sliding rod is connected to the connecting sleeve through a card slot, and the fixing nut is threadedly connected to the sliding rod.

[0014] By adopting the above technical solution, the connecting hole can play a role in limiting the sliding rod, effectively preventing the sliding rod from running off and misaligning, and is fixedly connected through the fixing nut.

[0015] Furthermore, the fixing rod is connected to the sliding rod through a card slot, and the sealing ring is connected to the telescopic rod through a card slot.

[0016] By adopting the above technical solution, the fixing rod and the sliding rod are used in cooperation, and the sealing ring can effectively play a sealing role, increasing the sealing performance of the telescopic rod.

[0017] Furthermore, the telescopic rod is bolted to the fixing block, and the fixing block is welded to the base.

[0024] By adopting the above technical solution, the design of the toothed ring facilitates the installation and fixation of the fixed plate and the connecting plate, and the fixing holes facilitate the through connection and use of the connecting bolts.

[0025] The specific working principle is as follows: during use, first install and fix the base, then connect the drilling machine to an external power supply for use. After starting the hydraulic motor, the hydraulic motor drives the drill bit to rotate at high speed. Immediately afterwards, when the operator is using the drill, by rotating the handwheel, the height of the sliding rod is adjusted. Affected by the pneumatic thrust, the distance between the fixed rod and the sliding rod changes, thereby realizing the lifting adjustment of the sliding rod driving the housing and the hydraulic motor as a whole. As the sliding rod descends, the drill bit begins to approach the surface of the drilling object, realizing rapid drilling operation on the object. During the whole use process, the drilling depth is adjusted by the height of the sliding rod. It is convenient and fast to use, without the need for additional connection and fixation, and can be used for convenient independent operation, thereby improving the convenience of using the drilling machine.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. By setting the handwheel and the adjuster to drive the sliding rod to lift in the fixed rod, the lifting of the housing and the hydraulic motor as a whole is realized. Lifting operation can be achieved without additional connection of other components, thereby improving the convenience of using the drilling machine;

[0028] 2. By setting a circular base, it is convenient for the installation and connection of the supporting external connecting seat, and two fixing methods, magnetic attraction and bolt connection, can be adopted, thereby improving the use effect during the erection of the drilling machine.
