Description

Technical Field

[0001] The utility model relates to the technical field of milling equipment, in particular to a fast clamping milling machine. Background Art

[0002] With the continuous development and popularization of optical equipment and instruments, the use of optical lenses is becoming more and more extensive, and the amount used is also increasing. The processing of optical lenses generally requires four steps: milling, fine grinding, polishing, and edging.

[0003] When fine grinding and polishing the lens, a bowl-shaped mold is needed. The inner wall of the bowl-shaped mold is bonded with sandpaper. The lens is mounted on a fixture, and the fixture is buckled in the mold. The lens is processed by rotating and adding grinding fluid. When processing the bowl-shaped surface on the mold, a milling machine is generally used for processing. For the mold structure, see Figure 1 When processing the mold, due to the arc-shaped side of the mold, only the lower part of the mold can be clamped and fixed. However, during milling, under the action of lateral force, the mold is prone to tilt, resulting in unstable mold clamping and large errors in processing. Utility Model Content

[0004] The utility model aims to provide a fast clamping milling machine, which can clamp the mold, avoid the mold from tilting during the processing, and reduce the processing error.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A fast clamping milling machine comprises a milling machine body, a clamping mechanism for clamping a mold is arranged on the milling machine body, the clamping mechanism comprises a mounting seat, a bracket fixedly arranged on the mounting seat, a first clamping arm and a second clamping arm hinged on the bracket, and a driving mechanism mounted on the mounting seat and connected to the first clamping arm and the second clamping arm for driving the first clamping arm and the second clamping arm to rotate;

[0007] A clamping block is hinged on the first clamping arm and the second clamping arm, and a matching surface matching the mold surface is arranged on the clamping block. A supporting platform is arranged on the bracket, and the clamping block is located above the supporting platform. A protective layer is arranged on the matching surface, and the protective layer is made of hard rubber material or plastic.

[0008] Among them, the driving mechanism includes a driving rod A, a driving rod B, a driving wheel, a gear, a rack and a telescopic rod. The driving wheel is rotatably installed on the bracket. The driving wheel is centrally symmetrically provided with a first push rod and a second push rod. The first and second push rods are vertically arranged on the side of the driving wheel. One end of the driving rod A is hinged to the first clamping arm, and the other end is hinged to the first push rod. One end of the driving rod B is hinged to the second clamping arm, and the other end is hinged to the second push rod. The driving wheel is connected to the gear through a connecting shaft, the rack is slidably installed on the mounting seat, the rack is meshed with the gear, the telescopic rod is horizontally installed on the mounting seat, and the movable end of the telescopic rod is connected to the rack.

[0009] Furthermore, support plates are arranged on both sides of the mounting seat, and the first clamping arm and the second clamping arm are hinged on the support plates through pins.

[0010] Preferably, a slide groove is provided on the mounting seat, a slider is provided in the slide groove, and the slider is fixedly connected to the rack.

[0011] It is further defined that the telescopic rod is a pneumatic or hydraulic telescopic rod.

[0012] Among them, mounting holes are arranged at the four corners of the mounting seat.

[0013] Furthermore, a groove is provided at the end of the rack, a weight sensor is provided in the groove, the weight sensor is connected to the movable end of the telescopic rod through a connecting block, and the weight sensor is connected to the telescopic rod through a controller.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model is mainly used for processing the bowl-shaped surface of the mold. In actual use, the mold is placed between the clamping blocks. At this time, the support table limits the mold, and the driving mechanism drives the first clamping arm and the second clamping arm to rotate, so that the clamping blocks are close to each other. Since the clamping blocks are provided with matching surfaces matching the mold surfaces, the clamping and fixing of the mold can be achieved after the clamping blocks are close to each other. Since a clamping area with the same shape as the mold is formed after the clamping blocks are close, the clamping and radial support of the mold can be achieved. During processing, the mold is tightly fixed and will not tilt, which can ensure the quality of processing, and can achieve rapid clamping of the mold, thereby improving the clamping efficiency.
