Description

Technical Field

[0001] The utility model relates to the technical field of prism processing, in particular to a processing and fixing tool for a prism. Background Art

[0002] A prism is a transparent object surrounded by two intersecting but non-parallel planes. It is mainly used to split light or disperse light beams. It is an important optical element made of transparent materials (such as glass, crystal, etc.) and is widely used in optical instruments. Prisms can be classified into equilateral prisms, right-angle prisms, etc. According to their properties and uses, they can also be divided into dispersion prisms, deflection or reflection prisms, rotation prisms and offset prisms. They are widely used in digital devices, science and technology, medical instruments and other fields.

[0003] During the prism processing, it is necessary to use a cutting tool to cut the prism into the desired shape, and use a grinding tool to grind its surface. During the cutting and grinding process, in order to prevent the prism from sliding, a fixed tool will be added to the workbench to fix the position of the prism, thereby increasing the stability of the prism during processing. However, after the fixed tool fixes the position of the prism, the position of the prism cannot be moved. When different areas of the prism need to be processed, the position is inconvenient to adjust, which affects the operation of the staff. Utility Model Content

[0004] The purpose of the utility model is to provide a prism processing and fixing tool to solve the problems raised in the above background technology.

[0007] As a further preferred embodiment of the present technical solution, the number of the fixing components is set to four, and the four fixing components include a first connecting rod, the surface of the first connecting rod is rotatably connected to an arc plate, the middle part of the arc plate is rotatably connected to a second connecting rod, the bottom end of the second connecting rod is fixedly connected to a connecting plate, the top end of the connecting plate is fixedly connected to a sliding rod, the top end of the sliding rod is fixedly connected to a fixing plate, the inner wall of the fixing plate is fixedly connected to a protective spring, and the end of the protective spring away from the fixing plate is fixedly connected to a rubber plate.

[0008] As a further preferred embodiment of the present technical solution, there are four fixing plates, the shape of the four fixing plates is L-shaped, and the number of the rubber plates corresponds to the number of the fixing plates.

[0009] As a further preferred embodiment of the present technical solution, a slide rail is fixedly connected to the top of the mounting plate, a moving block is slidably connected to the top of the slide rail, and the moving block is fixedly connected to the connecting plate.

[0010] As a further preferred embodiment of the present technical solution, the top of the mounting plate is fixedly connected with a supporting shell, the top of the supporting shell is provided with a slide groove, the number of the slide grooves is four, and the four slide grooves are matched with the slide rod.

[0011] As a further preferred embodiment of the present technical solution, an annular groove is provided on the top of the mounting frame, a limiting rod is slidably connected to the middle of the annular groove, a ball is movably installed on the bottom end of the limiting rod, and the limiting rod is fixedly connected to the mounting plate.

[0012] The utility model provides a prism processing and fixing tool, which has the following beneficial effects:

[0013] (1) The utility model adds a rotating assembly to the bottom end of the fixed tooling and controls it by turning a handle. When the prism needs to be rotated, the handle is rotated to make the rotating rod drive the first rotating shaft to rotate, and the driving gear rotates accordingly. Since the driving gear and the transmission gear are meshed, the transmission gear drives the second rotating shaft and the mounting plate to rotate. At the same time, the limit rod at the bottom end of the mounting plate slides in the annular groove of the mounting frame, thereby ensuring the stability of the mounting plate when rotating. A ball is arranged at the bottom end of the limit rod to improve the smoothness of the mounting plate when rotating.

[0014] (2) The utility model installs four sets of fixing components on the rotating plate and controls the opening and closing of the fixing components through a rotating motor. When in use, the prism is placed on the supporting shell, the rotating motor is started, and the connecting shaft drives the rotating plate to rotate. As the angle of the rotating plate changes, the arc plate rotates through the first connecting rod, and pulls the connecting plate and the slider to slide on the slide rail. The slide bar moves in the slide groove, so that the four fixing plates are brought closer to each other, and the position of the prism is fixed. When the prism contacts the rubber plate, the rubber plate squeezes the protective spring to make it contract, thereby giving the prism a certain displacement amount to prevent the fixing plate from moving too much and squeezing the prism to cause damage.
