Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the utility model are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the utility model. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

At least one embodiment of the present invention provides a silicon rod sample saw clamping device, which includes a base, two support ends, two clamping bodies, and a metal plate. In an embodiment, the two supporting ends are respectively installed at two opposite ends of the base. One ends of the two clamping main bodies which are arranged in parallel are respectively fixed at one supporting end, and the other ends of the two clamping main bodies which are arranged in parallel are respectively provided with a metal plate and are opposite to the other supporting end. One end of the external silicon rod sample is abutted against one supporting end, and the other end of the external silicon rod sample is uniformly clamped by two clamping main bodies which are arranged in parallel.

It is worth to be noted that, in the above embodiment, the silicon rod sample externally arranged is obtained by the combined action of the two clamping bodies and the supporting end: one end of the external silicon rod sample is abutted against one supporting end, the other end of the external silicon rod sample is uniformly fixed by applying clamping force by the two clamping main bodies, and the external silicon rod sample is clamped and loosened by the jacking acting force of the two clamping main bodies.

Preferably, the silicon rod sample saw clamping device can be suitable for clamping and cutting silicon rod samples with various shapes.

As some examples, as shown in fig. 1 to 3, the silicon rod sample saw clamping device may include a clamping body 1, a metal plate 2, a clamping body end wedge 3, a support end wedge 4, a support end 5, a base 6, and an external silicon rod sample 8. In the embodiment, two support ends 5 are respectively installed at two opposite ends of the base 6. One ends of two clamping bodies 1 which are arranged in parallel are respectively fixed at one supporting end 5, the other ends of the two clamping bodies are respectively provided with a metal plate 2 and are opposite to the other supporting end 5, and the clamping body end wedge blocks 3 are fixed at the free ends of the metal plates 2. The support end wedge 4 is fixed to a support end 5 and faces the two clamp bodies 1 arranged in parallel. One end of the external silicon rod sample 8 is abutted against the supporting end wedge 4, the other end of the external silicon rod sample 8 is abutted against the two clamping body end wedges 3, and then the external silicon rod sample 8 is uniformly applied with clamping force through the two clamping bodies 1 which are arranged in parallel.

It should be noted that one end of the external silicon rod sample 8 abuts against the supporting end wedge 4 and the other end of the external silicon rod sample 8 abuts against the two clamping body end wedges 3, and when the two clamping bodies 1 uniformly apply clamping force, the supporting end wedge 4 and the clamping body end wedges 3 have stretching force, and play a role in assisting and fixing the external silicon rod sample 8. The clamping force of the clamping body 1 for fixing the external silicon rod sample 8 can be adjusted through the telescopic degree of the clamping body 1, so that the external silicon rod sample 8 is prevented from being stressed too much or too little, namely, the operation elasticity is large.

Preferably, the material of the support end 5 may be a metal plate. And the material of the clamping body end wedge 3 and the supporting end wedge 4 can adopt engineering plastics with certain strength.

As further examples, two clamping bodies 1 fix the metal plate 2, in turn the clamping body end wedges 3 to each other by means of screws. It is worth mentioning that a gap is left between the two clamping bodies 1 arranged in parallel, and the two clamping bodies 1 arranged in parallel have the same distance (i.e. have a certain height relative to the base 5) with the base 6 respectively. Further, the two clamping bodies 1 are designed and installed independently in parallel, and a 15mm-25mm gap is required to be reserved between the two clamping bodies to ensure that the saw blade has a descending space in the cutting process.

It is worth mentioning that the two clamping bodies 1 can be designed in a cylinder-action or a mechanical-action manner for a flexible choice. Further, if the clamping body 1 is designed as a cylinder action type, the clamping body 1 can be driven to telescope by supplying and interrupting air using a 5bar air supply. If the clamping body 1 is designed to be in a mechanical action mode, the clamping body 1 can be driven to move by a mechanical arm in parallel and independently, and the clamping body 1 is stretched and contracted by using a rotary driving mode at the outer side, so that the external silicon rod sample 8 is clamped and loosened.

As another example, the silicon rod sample saw clamping device may be installed on the worktable 7, and when the silicon rod sample needs to be cut and processed, the cut external silicon rod sample 8 is firstly placed on the base 6, and then is fixedly clamped by the clamping body 1 to be cut and processed into a required sample shape.

The above-described embodiments should not be construed as limiting the scope of the utility model. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
