Clamp device of pressing ring of optical lens

Abstract

The invention discloses a clamp device of a pressing ring of an optical lens, which comprises a fixing seat, a tightening mechanism for tightening the pressing ring of the optical lens, and a torsionadjusting mechanism for adjusting the rotation torsion of the tightening mechanism; the torsion adjusting mechanism comprises a connection piece and a ball bearing; the connection piece is connected with the tightening mechanism and the fixing seat, and drives the tightening mechanism to rotate corresponding to the fixing seat; a cylindrical channel penetrating the fixing seat is opened on the fixing seat; the connection piece comprises a cylindrical first part; the first part is located in the cylindrical channel; a plurality of arc grooves are arranged along the circumference of the side wall of at least one of the first part and the cylindrical channel, and the ball bearing is arranged on the side wall of the other one; and, the ball bearing is abutted against the wall surface of the arc groove. By adoption of the clamp device of the pressing ring of the optical lens, the ball bearing moves from the current arc groove into another arc groove when the connection piece drives the tightening mechanism to rotate corresponding to the fixing seat; and thus, the rotation torsion of the tightening mechanism is controlled, and the quality stability of the lens is improved.

Description

technical field [0001] The invention relates to the technical field of optical lens press ring assembly, in particular to an optical lens press ring fastening device. Background technique [0002] With the advent of the high-definition era, industrial lenses, as optical system components, naturally keep pace with the times. The lens plays a vital role just like the human eye. The security industry is becoming more and more mature, the security awareness of the general public is gradually rising, and the market is also beginning to increase the demand for industrial lenses and the quality control requirements. [0003] At present, for industrial lens assembly, due to the complex mechanical structure and different application ranges, the requirements for lens stability are different. More and more lenses have many requirements in terms of product structure stability in addition to performance. There are also many requirements, such as: product vibration requirements, impact r...

Problems solved by technology

[0004] The existing press ring assembly methods all use manual hand-holding and manual tightening with tweezers or other simple fixtures. This method can only simply tighten the press ring and cannot quantify the torque, so it is easy to Differences lead to different tightness of the pressure ring after tightening; at the same time, it is difficult for human hands to control the balance and stability, and it is easy to damage the appearance of the lens or cause injury to the operator
