The cam is secured to the upper edge of the upper frame by a spring which is secured to the cam face of the lens during movement.

[0007] By adopting the above technical solution, the optical lens is placed vertically between the lower pressure plate and the upper pressure plate. After the optical lens is fitted with the baffle, the upper pressure plate is pushed, and then the distance between the upper pressure plate and the lower pressure plate is reduced until the two are fitted with the optical lens. The threaded rod is rotated so that the threaded rod is against the optical lens, thereby clamping the optical lens from four directions, clamping it firmly, and ensuring the polishing effect.

[0008] In a preferred example, the present invention can be further configured as follows: the multiple bending portions of the lower pressing plate and the upper pressing plate are all arranged as arc surfaces.

[0009] In a preferred example, the present invention can be further configured as follows: a plurality of flat plates are grouped in pairs, and are arranged into two groups, and the two groups of flat plates are vertically symmetrical about the baffle.

[0010] In a preferred example, the present invention can be further configured as follows: the outer end of the threaded rod is set to a spherical surface, and the threaded rod is made of plastic.

[0011] In a preferred embodiment, the present utility model can be further configured as follows: two receiving plates are respectively attached to both sides of the lower pressing plate, and the thickness of the receiving plate is one-half of the thickness of the lower pressing plate.

[0012] In a preferred embodiment, the present utility model can be further configured as follows: a rotating rod is installed on the top of the synchronous pulley, and the rotating rod is eccentrically arranged with respect to the center of the synchronous pulley.

[0013] By adopting the above technical solutions, the beneficial effects achieved by the present utility model are as follows:

[0014] 1. In the present utility model, the optical lens is vertically placed between the lower pressing plate and the upper pressing plate. After the optical lens is attached to the baffle, the upper pressing plate is pushed, and then the distance between the upper pressing plate and the lower pressing plate is reduced until they are attached to the optical lens. At this time, the threaded rod is rotated to make the threaded rod abut against the optical lens, thereby clamping the optical lens from four directions. The clamping is firm, ensuring the grinding effect.

[0015] 2. In the present utility model, after the optical lens is clamped, the rotating rod is rotated, and the two synchronous pulleys drive the sandpaper to rotate. The sandpaper rubs the surface of the optical lens to achieve the grinding of the optical lens. The structure is simple and the grinding is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0025] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.

[0026] The following describes an optical lens grinding fixture provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0027] Embodiment 1:

[0028] Combined with Figures 1-4 As shown, an optical lens grinding fixture provided by the present utility model includes a clamping mechanism 100, a pressing mechanism 200, and a grinding mechanism 300. The clamping mechanism 100 includes a lower pressing plate 110, an upper pressing plate 120 provided on the top of the lower pressing plate 110, a plurality of flat pieces 130 movably connected between the lower pressing plate 110 and the upper pressing plate 120, and a baffle 140 slidably penetrating through the top of the upper pressing plate 120. The bottom of the baffle 140 is in contact with the top of the lower pressing plate 110.

[0029] The pressing mechanism 200 includes a U-shaped plate 210 connected to one end of the lower pressing plate 110 and a threaded rod 220 penetrating through the U-shaped plate 210.

[0030] The grinding mechanism 300 includes two receiving plates 310 clamped to the baffle 140, a positioning rod 320 connected to the top of the receiving plates 310, a synchronous pulley 330 movably sleeved outside the positioning rod 320, and a sandpaper 340 connected between the two synchronous pulleys 330. The outer wall of the baffle 140 is in contact with the inner wall of the sandpaper 340.

[0031] Further, the plurality of flat pieces 130 are grouped in pairs and set into two groups. The two groups of flat pieces 130 are vertically symmetric with respect to the baffle 140. With this layout design, the upper pressing plate 120 and the lower pressing plate 110 can be firmly connected.

[0032] Further, the outer end of the threaded rod 220 is provided as a spherical surface. The threaded rod 220 is made of plastic. After the outer end of the threaded rod 220 is provided with a spherical surface, it can prevent the end face from bruising the user.

[0033] Further, the two receiving plates 310 are respectively attached to both sides of the lower pressing plate 110. The thickness of the receiving plate 310 is one-half of the thickness of the lower pressing plate 110. With this thickness design, the load of the receiving plate 310 on the baffle 140 can be reduced.

[0034] Embodiment 2:

[0035] Combined Figures 1-3 As shown, on the basis of the first embodiment, the multiple bent portions of the lower pressing plate 110 and the upper pressing plate 120 are all provided with arc surfaces. With this structural design, the use safety of the device is improved.

[0036] Embodiment Three:

[0037] Combined Figure 1 and Figure 4 As shown, in the above embodiment, a rotating rod 400 is installed on the top of the synchronous pulley 330, and the rotating rod 400 is eccentrically arranged with respect to the center of the synchronous pulley 330. By setting the rotating rod 400, it is convenient for the staff to rotate the synchronous pulley 330.

[0038] The working principle and usage process of the present utility model: When the device is put into actual use, the optical lens is vertically placed between the lower pressing plate 110 and the upper pressing plate 120. After the optical lens is in contact with the baffle 140, the upper pressing plate 120 is pushed. Then, the distance between the upper pressing plate 120 and the lower pressing plate 110 is reduced until they are in contact with the optical lens. At this time, the threaded rod 220 is rotated to make the threaded rod 220 abut against the optical lens, thereby clamping the optical lens from four directions firmly. Then, the rotating rod 400 is rotated, and the two synchronous pulleys 330 drive the sandpaper 340 to rotate, and the sandpaper 340 rubs the surface of the optical lens to achieve the grinding of the optical lens.

[0039] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
