Description

Technical Field

[0001] The utility model belongs to the technical field of oil drilling instruments, in particular to a surface polishing machine for a wireless while-drilling inclinometer. Background Art

[0002] The exterior of the wireless inclinometer is made of metal. On the one hand, when the instrument is working underground, it will be corroded by drilling fluid and gas or liquid seeping from the formation. On the other hand, after the instrument is stored, the surface will lose its luster or even rust, which will adversely affect the roughness and aesthetics of the surface of the wireless inclinometer.

[0003] Wireless inclinometers typically require surface polishing during production or maintenance. Existing polishing methods include manual polishing, which is time-consuming and labor-intensive, with poor polishing results. Existing tube polishing machines have insufficient holding power, making the instrument prone to vibration during polishing. Furthermore, the instrument's appearance is highly demanding, requiring the outer diameter of the tube to remain consistent, resulting in a narrow polishing range.

[0004] In order to overcome the shortcomings or deficiencies of the existing polishing method for wireless while drilling inclinometers, it is necessary to provide a surface polishing machine for wireless while drilling inclinometers. Summary of the Invention

[0005] The purpose of the utility model is to provide a surface polishing machine for a wireless while drilling inclinometer in view of the above-mentioned deficiencies in the prior art, so as to improve the polishing efficiency of the wireless while drilling inclinometer.

[0008] The polishing device includes a slide base mounted on the slide rail device, a manual slide provided on the slide base, a polishing wheel mounted on the manual slide, and a second drive motor, and the polishing wheel rotates under the drive of the second drive motor;

[0009] The manual slide controls the movement of the second drive motor in the Y axis, while the handle installed on the slide base controls the movement of the polishing device in the X axis.

[0010] The first clamping device and the second clamping device have the same structure and are symmetrically arranged, and both include a spindle seat, a rotating shaft assembly arranged on the spindle seat, and a chuck coaxially connected to the rotating shaft assembly, and the core of the rotating shaft assembly is set as a large through hole.

[0011] Bearings are installed at both ends of the main shaft of the rotating shaft assembly, and the outer circle of the bearing is fixed on the equipped main shaft box, and the main shaft is fixed by a locking nut.

[0012] The chuck is configured as a three-jaw chuck.

[0013] The first drive motor and the second drive motor are both adjustable speed motors.

[0014] The first drive motor is connected to the first clamping device for synchronous rotation via a synchronous wheel.

[0015] The beneficial effects of the utility model are:

[0016] (1) The surface polishing machine for the wireless downhole inclinometer is installed on a workbench. The first clamping device and the second clamping device are installed on the same axis. One end of the instrument to be polished is fixed on the first clamping device and the other end is fixed on the second clamping device, and the second clamping device is installed on the slide rail device.
