Description

TECHNICAL FIELD

[0001] The utility model mainly relates to angle adjustment technical field, specifically relates to a structure that combination is adjusted to angle has level. BACKGROUND

[0002] There are many brands and models of angle-adjustable platforms on the market for machine tools, drilling machines, milling machines, etc. The angle-adjustable platforms of the workbench generally have wider angle adjustment capabilities to meet the needs of different application scenarios and industries.

[0003] There are common angle adjustment designs, and the fixed angle mode is generally as follows:

[0004] 1. Two relative rotating parts are fixed in angle by bolts (as shown in the accompanying drawings), at this time the bearing capacity of the platform depends on the strength of the bolts, the two parts are fixed relative by the bolts, and the force changing the angle of the platform becomes the shear force on the bolts; Figure 1

[0005] If you want to change the angle of the platform, you need to align the bolts to other angle holes and fix them, or the bolts will break;

[0006] The advantages of this structure are strong and stable bearing capacity, and the disadvantages are that it can only adjust the angle in steps, and a large space is required for thread hole processing.

[0007] 2. Two relative rotating objects are fixed in angle by the friction force generated by tightening the bolts between the two contact surfaces (as shown in the accompanying drawings), the bearing capacity of this structure depends on the size of the friction force (the pressure of the bolts on the two surfaces and the surface friction coefficient); Figure 2

[0008] If you want to change the relative angle, you need to loosen the bolts, or the torque applied is greater than the torque generated by the static friction relative to the rotating shaft;

[0009] The advantages of this structure are that it can be adjusted steplessly, and the disadvantages are that the bearing capacity is poor, and a large space is required for adjustment route processing. INVENTION CONTENTS
