Embodiment 1

[0030] refer to figure 2 , is a coaxiality correction mechanism for installing lens grinding tools disclosed in the present invention, including a jig assembly 1, and the jig assembly 1 includes a relay jig 11, a jig base 12, a spindle 13, and a grinder 14 And the locking screw 15, the relay fixture 11 is detachably fixed on the fixture base 12 through the locking screw 15, the main shaft 13 is rotated and set on the center line of the relay fixture 11, and the grinding tool 14 is installed on the relay fixture 11 above.

[0031] refer to image 3 , the present invention also includes an adjustment mechanism 2, the adjustment mechanism 2 includes an adjustment screw 21 and a spring 22, the bottom of the relay fixture 11 is provided with a groove 111 for the fixture base 12 to be embedded, the inner wall of the groove 111 and the fixture base 12 There is a gap between the outer walls, the adjusting screw 21 is installed on the outer wall of the relay fixture 11 and one end a...

Embodiment 2

[0037]A kind of coaxiality correcting mechanism that is used to install lens grinding wheel 14, and the difference of embodiment one is that, refer to Figure 4 , the outer wall of the jig base 12 is provided with a second installation groove 121 for the spring 22 to be embedded, the second installation groove 121 is located on the same straight line as the adjustment screw 21, and the spring 22 is in a natural state, and the spring 22 is far away from the second installation One end of the bottom of the groove 121 passes through the second installation groove 121 and abuts against the inner sidewall of the groove 111 .

[0038] In the above two installation positions of the spring 22, one end of the spring 22 passes through the first installation groove 112 or the second installation groove 121, and the elastic force of the length of the spring 22 after deformation must be greater than that of the relay fixture 11 and the fixture. The frictional force between the jig bases 12...

Abstract

The invention relates to a coaxiality correction mechanism for installing a lens grinding tool. The mechanism comprises a jig assembly, the jig assembly comprises a relay jig, a jig base, a main shaft, the grinding tool and a locking screw, the relay jig is detachably fixed on the jig base through the locking screw, the main shaft is rotatably arranged on the center line of the relay jig, and the grinding tool is arranged above the relay jig. The mechanism further comprises an adjusting mechanism, the adjusting mechanism comprises an adjusting screw and a spring, a groove for embedding the jig base is formed at the bottom of the relay jig, a gap is formed between the inner wall of the groove and the outer side wall of the jig base, the adjusting screw is installed on the outer side wall of the relay jig, one end of the adjusting screw abuts against the outer side wall of the jig base, and the spring is arranged at the other side of the length extension line of the adjusting screw and used for providing restoring force and driving the relay jig to move on the horizontal plane so as to eliminate the thread idle stroke gap. The coaxiality of the grinding tool and the main shaft can be adjusted on a grinding tool transition joint through the adjusting mechanism, and the adjusting manner is simple.

Description

technical field [0001] The invention relates to the technical field of instrument lens grinding equipment, in particular to a coaxiality correction mechanism for installing lens grinding tools. Background technique [0002] refer to figure 1 , is an existing lens polishing equipment, which includes a swing-up machine A and a mount B located below the swing-up machine. The swing-up machine A includes a frame a, an elastic rib a, and a pressure shaft a. The pressure shaft a moves through It is arranged on the frame a, and the two ends of the elastic rib a are fixed on the frame a and arranged on the top of the pressure shaft a, and the elastic rib a uses the elastic force of its middle part to provide pressure for the pressure shaft a to press down the lens. [0003] The mounting base B includes a jig base b, a relay jig b, and a grinding tool. The relay jig b is detachably fixed on the jig base b through a plurality of bolts, and the grinding tool is installed in the relay j...
