The utility model discloses the device is simple, and it is convenient to install and dismantle, but can once only assemble a plurality of camera lenses, and assembly efficiency promotes greatly, has very strong practicality.
Description
Technical Field
The utility model relates to a camera lens assembly field, concretely relates to camera lens rapid Assembly device.
Background
The lens belongs to high-precision optical products, so the precision of parts is required to be high, the precision of the fit of centering parts is also required to be high, the part design is mainly in transition fit or small clearance fit, and the lens can be pressed into the lens barrel only with certain force in the optical assembly process of the lens.
Most of the existing lens assemblies adopt a vacuum suction mode to suck optical lenses, then the optical lenses are pressed into a lens barrel, and then parts such as a spacing ring and the like are sequentially placed, so that the assembly efficiency is low, and the assembly precision cannot be guaranteed.
Disclosure of Invention
According to the problem that the background art provided, the utility model provides a camera lens rapid Assembly device solves, it is right next the utility model discloses do further to explain.
A quick lens assembling device comprises a base, wherein a plurality of assembling positions are connected to the base, each assembling position comprises a sleeve, an ejector rod and a return spring, the ejector rods are connected to the base, the sleeves and the return springs are sleeved outside the ejector rods, one end of each return spring is in contact with the bottom end of each sleeve, and the other end of each return spring is in contact with the base; the inner diameter of the sleeve is larger than the diameters of all spare and accessory parts of the lens module to be assembled, and two opposite avoiding grooves are formed in the sleeve.
Preferably, when the device is in a free state, the self weight of the device enables the reset spring to deform and displace, and the lowest part of the avoiding groove is just flush with the upper top surface of the ejector rod; when the accessories are placed for the first time, the edges of the accessories can be exposed out of the avoiding grooves, and adjustment by an assembler is facilitated.
Preferably, the base is provided with a positioning groove, and the ejector rod is placed in the positioning groove to limit the ejector rod from moving laterally.
Preferably, the base is provided with through bolt mounting holes at the positioning groove and the ejector rod, and the ejector rod is fixed on the base through an assembly bolt.
Preferably, the diameter of the positioning groove is larger than that of the ejector rod, and the lower end of the return spring is arranged in the positioning groove.
Has the advantages that: compared with the prior art, the utility model discloses the device is simple, and it is convenient to install and dismantle, but can once only assemble a plurality of camera lenses, and assembly efficiency promotes greatly, has very strong practicality.
Drawings
FIG. 1: the structure of the utility model is shown schematically;
in the figure: base 1, constant head tank 11, sleeve 2, constant head tank 21, ejector pin 3, reset spring 4, lens module 5.
Detailed Description
A specific embodiment of the present invention will be described in detail with reference to fig. 1.
A quick lens assembling device comprises a base 1, wherein a plurality of assembling positions are connected to the base 1, each assembling position comprises a sleeve 2, an ejector rod 3 and a return spring 4, the ejector rod 3 is connected to the base 1, the sleeve 2 and the return spring 4 are sleeved outside the ejector rod 3, one end of the return spring 4 is in contact with the bottom end of the sleeve 2, and the other end of the return spring 4 is in contact with the base 1; the inner diameter of the sleeve 2 is larger than the diameter of all the parts of the lens module to be assembled, and two opposite avoiding grooves 21 are arranged on the sleeve.
When using, all accessories of the lens module 5 of assembling are held between fingers by the assembler in proper order to place downwards directly over the sleeve 2, the clearance groove 21 on the two sides of the sleeve 2 improves the displacement space of holding between fingers, the accessories of the lead run are placed on the ejector rod 3, finally the lens cone is pressed downwards, and all parts are taken into the lens cone to complete the assembling.
In this embodiment, the return spring 4 is used to support the sleeve 2, and makes the assembly and disassembly of all components very convenient.
When sleeve 2 is in free state, its dead weight makes reset spring 4 take place deformation, after reset spring 4 is stable, sleeve 2 keeps away the lowest of groove 21 and ejector pin 3's last top surface parallel and level just for when placing accessories for the first time, can make accessories edge expose in keeping away groove 21, the assembly personnel of being convenient for adjust.
The base 1 is provided with a positioning groove 11, and the ejector rod 3 is placed in the positioning groove 11 to limit the ejector rod 3 to laterally move.
The base 1 is provided with through bolt mounting holes at the positioning groove 11 and the ejector rod 3, and the ejector rod 3 is fixed on the base 1 through an assembly bolt.
The diameter of the positioning groove 11 is larger than that of the ejector rod 3, and the lower end of the return spring 4 is arranged in the positioning groove 11.
In this embodiment, four assembling positions distributed in a regular quadrangle are connected to the base 1 to improve the efficiency.
The utility model discloses the device is simple, and it is convenient to install and dismantle, but can once only assemble a plurality of camera lenses, and assembly efficiency promotes greatly, has very strong practicality.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
