Technical Field

[0001] The utility model relates to the technical field of optical component fine grinding fixtures, in particular to an adjustable optical component fine grinding fixture. Background Art

[0002] Optical parts, also known as optical elements, are the basic components of optical systems. Most optical parts play the role of imaging, such as lenses, prisms, reflectors, etc. In addition, there are some parts that play special roles in optical systems (such as splitting, image transmission, filtering, etc.), such as gratings, filters, gratings for optical fiber parts, etc.

[0003] In order to achieve optical precision during the production of optical parts, the initially produced optical parts need to be polished and finished. A fine grinding machine is needed for the polishing and finishing. The optical parts are placed on the fine grinding machine and clamped and fixed with the fine grinding fixture on the fine grinding machine to ensure that the optical parts do not shake or move during polishing, and to ensure that the quality of the polished optical parts meets the product quality standards.

[0004] However, in the prior art, the fixture used for fine grinding of optical parts is an integral part, and once damaged, it needs to be replaced as a whole, resulting in high maintenance and use costs. Utility Model Content

[0008] Preferably, the positioning clamp block comprises a positioning plug plate, the bottom end of which is plugged into the interior of the base and a plug slot is formed through the bottom end.

[0009] Preferably, the arc-shaped plug-in strip is plugged into the positioning slot and passes through the plug-in slot, the arc length of the plug-in slot is consistent with the arc length of the arc-shaped plug-in strip, and the height of the plug-in slot is consistent with the thickness of the arc-shaped plug-in strip.

[0012] Preferably, a contact strip is fixed to the outer side of the clamping plate, and both the upper and lower ends of the contact strip are provided with inclined surfaces with an inclination angle of forty-five degrees.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. When the positioning plate and the clamping plate are broken or damaged due to accidents during use, if the clamping plate is broken or damaged, just slide the clamping plate, separate the bottom end of the clamping plate from the top end of the positioning plate, and then install a new clamping plate. If the positioning plate is damaged, just take out the arc-shaped plug strip from the inside of the base, separate the positioning plate from the base, replace the new positioning plate and assemble the original clamping plate with the new positioning plate. Just replace the damaged positioning plate or clamping plate, which reduces the cost of use.

[0015] 2.

The inner wall of the base 1 is provided with a plurality of positioning grooves 5 distributed in a circular array around the base 1. An arc-shaped plug-in strip 4 is slidably inserted into the inner side of the positioning groove 5. A plurality of positioning clamps 3 distributed in a circular array around the axis of the base 1 are slidably installed on the upper surface of the base 1. The number of the positioning clamps 3 is consistent with the number of the positioning grooves 5. The sliding arc-shaped plug-in strip 4 is used to clamp and fix the positioning clamps 3 on the surface of the base 1, so as to facilitate the replacement of damaged positioning clamps 3.

[0024] As the preferred technical solution of this embodiment, Figure 2 and Figure 3 As shown, the positioning clamp 3 includes a positioning plug plate 31, the bottom end of the positioning plug plate 31 is inserted into the interior of the base 1 and a plug groove 34 is opened through the bottom end, the arc plug strip 4 is inserted into the positioning groove 5 and passes through the plug groove 34, the arc length of the plug groove 34 is consistent with the arc length of the arc plug strip 4, the height of the plug groove 34 is consistent with the thickness of the arc plug strip 4, and the arc plug strip 4 is used to lock the bottom of the positioning plug plate 31 to ensure that the positioning plug plate 31 will not shake.

[0025] As the preferred technical solution of this embodiment, Figure 4 and Figure 5 As shown, a clamping plate 32 is slidably installed on the inner side of the positioning plug plate 31, and the bottom end of the clamping plate 32 and the top end of the positioning plug plate 31 are both bent in a U shape and slidably engaged with each other, and a clamping arc strip 33 is fixed to the inner side of the clamping plate 32, and an anti-slip groove 36 is provided on the inner side of the bottom end of the clamping plate 32, and an anti-slip strip 37 is fixed to the inner side of the top end of the positioning plug plate 31, and the anti-slip strip 37 is slidably engaged with the inner side of the anti-slip groove 36, and the top end of the positioning plug plate 31 and the bottom end of the clamping plate 32 are bent in a U shape and have a certain elasticity, so that the positioning plug plate 31 and the clamping plug plate 32 are not easy to break, and the anti-slip strip 37 is engaged in the anti-slip groove 36 to ensure that the clamping plate 32 and the positioning plug plate 31 will not be easily separated after being connected.
