Description

Technical Field

[0001] The utility model belongs to the field of power heads and relates to a power head, in particular to a novel guide structure of a power head. Background Art

[0002] The power head can realize the main motion and feed motion, and has a power component for automatic workpiece circulation. A relatively simple variable speed transmission mechanism, in various forms, the basic principle is that the motor drives a pulley variable speed mechanism, which can realize boring, milling, drilling and other functions, and some have guide rails, which can achieve a small range of linear motion.

[0003] Existing power heads mostly use a guide rail or a slide rail in conjunction with a slider for feeding movement. When the power head rotates, it will be subjected to tangential loads. Long-term use will cause the stability of the guide rail to decrease, thereby affecting the accuracy of the feeding action. In addition, most power heads have an integrated housing, which makes it inconvenient to disassemble and adjust the position of the slider. Summary of the invention

[0004] The purpose of the utility model is to provide a new type of guide structure of a power head with a fine-tunable sliding block in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of guiding structure of a power head, including a frame, characterized in that a power head body is arranged at the front end of the frame, the power head body is composed of a barrel, a box assembly, a driving shaft and a synchronous wheel assembly, a plurality of guide rails are arranged on the barrel, the box assembly is composed of a front end box, a box body and a rear end box, adjustment holes are opened on the front end box and the rear end box relative to the guide rails, a plurality of front end sliders are arranged at the front end of the guide rails and relative to the adjustment holes, and a plurality of rear end sliders are arranged at the rear end of the guide rails and relative to the adjustment holes.

[0006] In the above-mentioned guide structure of a novel power head, a driving motor 1 is arranged at the rear end of the frame, and the driving motor 1 controls the driving shaft to rotate through the synchronous wheel assembly.

[0007] In the above-mentioned guide structure of a new type of power head, a screw is arranged between the box assembly and the frame, a driving motor 2 is arranged at the rear end of the frame, the motor shaft of the driving motor 2 is connected to the screw through a coupling, and a screw limit block is arranged at the front end of the screw relative to the box assembly.

[0008] In the above-mentioned guide structure of a new type of power head, the front and rear ends of the box assembly are respectively provided with a rubber pad front cover and a rubber pad rear cover, the front end box is bolted to the box body, and the rear end box is bolted to the box body.

[0009] Compared with the prior art, the utility model is provided with several slide rails, and sliders are provided at the front and rear ends of the slide rails to increase the stability of the box body and improve the feeding accuracy. The rubber pad rear cover and the front cover prevent impurities from entering the interior and causing wear on the sliders. The adjustment holes provided can fine-tune the connection position of the sliders with the front and rear box bodies as needed. The separate setting of the box body assembly makes it more convenient to install the sliders. BRIEF DESCRIPTION OF THE DRAWINGS
