Description

Technical Field

[0001] The present application relates to the field of glasses processing, and in particular to a glasses frame clamp. Background Art

[0002] Glasses are optical instruments used to improve vision, protect the eyes or for decorative purposes. They can correct a variety of vision problems, including myopia, hyperopia, astigmatism, presbyopia, strabismus or amblyopia. Glasses are composed of lenses and frames.

[0003] There are various types of eyeglass frames used to support eyeglass lenses. In the production of eyeglass frames, there are one-piece resin eyeglass frames and eyeglass frames welded from metal frames. When these eyeglass frames are polished or assembled, clamps are generally required to fix the frames, and then the operators perform the processing.

[0004] When processing the eyeglass frame, it is often necessary to process different positions of the eyeglass frame, so it is necessary to use the clamp to release the clamp of the eyeglass frame back and forth, and then use the clamp to clamp the eyeglass frame again. When adjusting the position of the eyeglass frame, the eyeglass frame is clamped repeatedly, which makes it more troublesome to process the eyeglass frame. Utility Model Content

[0005] The purpose of the present application is to solve the problem proposed in the above background technology that when processing different positions of the glasses frame is required, it is necessary to use a clamp to release the clamp of the glasses frame back and forth, and then use the clamp to clamp the glasses frame again, and when adjusting the position of the glasses frame, the glasses frame is repeatedly clamped, which makes the processing of the glasses frame more troublesome. The present application provides a glasses frame clamp.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A glasses frame clamp comprises an electric slide rail, two first clamping blocks are slidably connected to the electric slide rail, a second clamping block is arranged on one side of the first clamping block, the second clamping block is fixedly connected to the electric slide rail, a clamping block 1 is fixed to the first clamping block, a clamping block 2 is arranged on the second clamping block, reserved openings are provided on the clamping block 1 and the clamping block 2, a clamping rotation mechanism is arranged between the clamping block 1 and the clamping block 2, and a clamping protection mechanism is arranged between the second clamping block and the clamping block 2.

[0008] By adopting the above technical solution, the first clamping block drives the clamping block 1 to approach the clamping block 2 on the second clamping block. Under the action of the clamping protection mechanism, the clamping rotation mechanism on the clamping block 1 and the clamping block 2 clamps the glasses frame. When the glasses frame needs to be rotated to process other areas, the clamping rotation mechanism is used to drive the glasses frame to rotate, so that the position of the glasses frame exposed between the clamping block 1 and the clamping block 2 can be easily changed, so as to facilitate the processing of the glasses frame.

[0009] Furthermore, the clamping and rotating mechanism includes a clamping plate 1 rotatably connected to a clamping block 1, a clamping plate 2 rotatably connected to a clamping block 2, a rotating rod fixed to the clamping plate 1, the rotating rod passes through the clamping block 1 and is rotatably connected to the clamping block 1, and a clamping assembly is provided on the rotating rod.

[0010] By adopting the above technical solution, the clamping plate 1 on the clamping block 1 and the clamping plate 2 on the clamping block 2 clamp the eyeglass frame, and the rotating rod is rotated, and the rotating rod drives the clamping plate 1 to rotate, so that the angle of the clamped eyeglass frame can be easily adjusted, and the processing position of the eyeglass frame can be easily adjusted.

[0011] Furthermore, the clamping assembly includes a rotating knob arranged at the end of the rotating rod away from the clamping plate, a clamping ring 1 is fixed on the rotating knob, a clamping ring 2 is arranged on one side of the clamping ring 1, the clamping ring 2 is fixedly connected to the clamping block 1, and clamping teeth are provided on both the clamping ring 1 and the clamping ring 2.

[0012] By adopting the above technical solution, the rotating knob drives the rotating rod to rotate, and then the clamping ring 1 on the rotating knob and the clamping ring 2 on the clamping block 2 are clamped together, so that the rotating rod and the clamping ring 1 can be easily fixed.

[0013] Furthermore, a sliding rod is slidably connected to the rotating rod, and one end of the sliding rod is fixedly connected to the rotating knob.

[0014] By adopting the above technical solution, the sliding rod is used to support the rotating knob, so that the rotating knob can be easily moved with the clamping ring 1 away from or close to the clamping ring 2, and the rotating knob can easily drive the rotating rod to rotate.

[0015] Furthermore, a limit spring is arranged between the sliding rod and the rotating rod, and both ends of the limit spring are fixedly connected to the rotating rod and the sliding rod.

[0016] By adopting the above technical solution, when the rotating knob is released, the clamping ring 1 and the clamping ring 2 on the rotating knob are pulled together by the limit spring, thereby reducing the possibility of the clamping ring 1 and the clamping ring 2 being separated when the rotating knob is not in use.

[0017] Furthermore, the clamping protection mechanism includes a sliding block fixed on the second clamping block, the second clamping block is provided with a sliding groove, the sliding block is located in the sliding groove and is slidably connected to the second clamping block, a clamping spring is provided in the sliding groove, both ends of the clamping spring are fixedly connected to the sliding block and the second clamping block, and a locking assembly is provided on one side of the sliding block.

[0018] By adopting the above technical solution, when the clamping block 1 and the clamping block 2 drive the clamping plate 1 and the clamping plate 2 to clamp the glasses frame, the clamping block 2 is supported by the clamping spring, thereby reducing the possibility of damage to the glasses frame due to excessive clamping force when the clamping block 1 and the clamping block 2 are clamping the glasses frame.

[0019] Furthermore, the locking assembly includes a threaded rod threadedly connected to the second clamping block, one end of the threaded rod is rotatably connected to a resistance block, the resistance block is slidably connected to the second clamping block, and the resistance block is in resistance to the side of the sliding block.

[0020] By adopting the above technical solution, after the clamping plate 1 and the clamping plate 2 clamp the glasses frame, the threaded rod is rotated to make the resistance block on the threaded rod resist the sliding block, so that the clamping block 1 on the sliding block cannot move, thereby allowing the clamping plate 1 and the clamping plate 2 to remain stable after clamping the glasses frame.

[0021] Furthermore, a plurality of conflicting teeth are fixed on a side of the conflicting block close to the sliding block, and the conflicting teeth conflict with the sliding block.

[0022] By adopting the above technical solution, the abutment teeth on the abutment block abut against the sliding block, thereby reducing the possibility of sliding between the sliding block and the abutment block.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present application clamps the eyeglass frame by the clamping plate 1 on the clamping block 1 and the clamping plate 2 on the clamping block 2 when the clamping block 1 and the clamping plate 2 are close to each other. When the angle of the eyeglass frame clamped by the clamping plate 1 and the clamping plate 2 needs to be changed, the rotating knob is pulled to separate the clamping teeth on the clamping ring 1 on the rotating knob from the clamping teeth on the clamping ring 2. Then the rotating knob is twisted to allow the rotating knob to drive the sliding rod, which in turn drives the rotating rod to rotate, so that the rotating rod drives the clamping plate 1 to rotate, and then the clamping plate 1 drives the eyeglass frame and the clamping plate 1 to rotate. After rotation, the rotating knob is released, and then the clamping ring 1 and the clamping ring 2 on the rotating knob are re-clamped together under the pull of the limit spring, so as to restrict the clamping plate 1 and prevent the clamping plate 1 from rotating. This achieves the purpose of conveniently adjusting the angle of the clamped eyeglass frame and conveniently adjusting the processing position of the eyeglass frame for processing.

[0025] 2. In the present application, when the clamping block 1 and the clamping block 2 are close to each other, the clamping plates 1 and 2 on the clamping block 1 and the clamping block 2 come into contact with the eyeglass frame, and then the clamping block 1 pushes the eyeglass frame, and the eyeglass frame pushes the clamping block 2, so that the sliding block of the clamping block 2 slides in the sliding groove and squeezes the clamping spring, and then, under the support of the clamping spring, the clamping block 2 is clamped in the direction of the eyeglass frame, so that the clamping plates 1 and 2 completely clamp the eyeglass frame, and then the threaded rod is rotated to allow the threaded rod to move on the second clamping block, so that the resistance block on the threaded rod comes into contact with the sliding block, and under the action of the resistance teeth on the resistance block, the sliding block cannot move in the sliding groove, so that the eyeglass frame between the clamping plate 1 and the clamping plate 2 maintains the clamping stability, thereby achieving the purpose of reducing the possibility of damage to the eyeglass frame due to excessive clamping force when the clamping block 1 and the clamping block 2 are clamping the eyeglass frame.
