Clamp for polishing and grinding plate-shaped sample

Abstract

The utility model relates to a clamp for polishing and grinding plate-shaped samples, which comprises a clamping mechanism capable of clamping a plurality of plate-shaped samples at the same time, and is characterized in that a containing part capable of containing a supporting piece is arranged on the clamping mechanism, and the clamping mechanism can keep a preset interval with a reference plane by means of the supporting piece; when the clamping mechanism is in an open state, the clamped plate-shaped samples can fall to a reference plane under the action of gravity so as to be located on the same polishing and grinding surface, compared with the prior art, the clamping mechanism has the advantages that the clamping mechanism can clamp a plurality of samples at the same time through the containing part capable of containing the supporting piece, and the clamping effect is good. In addition, the to-be-processed planes of the multiple samples can be quickly aligned with the reference plane by means of the supporting pieces, and the supporting pieces can be prevented from being lost, so that the labor intensity of workers is reduced, and the working efficiency is improved.

Claims

1. A fixture for polishing a plate-shaped specimen, comprising a clamping mechanism (1) capable of simultaneously clamping a plurality of plate-shaped specimens, characterized in that: The clamping mechanism (1) is provided with a receiving portion (3) capable of receiving the support member (2). The clamping mechanism (1) can maintain a preset interval (H) with the reference plane (N) by means of the support member (2). Thus, when the clamping mechanism (1) is in an open state, each clamped plate-shaped specimen can fall to the reference plane (N) under the action of gravity to be on the same polishing surface.

2. The clamp according to claim 1, characterized in that: The clamping mechanism (1) also includes a first clamping plate (11) and a second clamping plate (12) arranged relatively to each other, and an opening / closing mechanism (13) for operating the first clamping plate (11) or the second clamping plate (12) to move closer to or farther away from each other. Correspondingly, the support member (2) is directly arranged on the first clamping plate (11) and the second clamping plate (12), and the storage portion (3) is a vertical guide hole also provided on the first clamping plate (11) and the second clamping plate (12). A locking mechanism (31) is provided on the storage portion (3) for locking the support member (2) when it is retracted therein.

3. The clamp according to claim 2, characterized in that: The locking mechanism (31) comprises a lock seat (32) arranged inside the storage portion (3); correspondingly, a lock tongue (21) adapted to the lock seat (32) is arranged on the support member (2); the locking mechanism (31) further comprises a transmission mechanism (33) for disengaging the lock tongue (21) from the lock seat (32).

4. The clamp according to claim 3, characterized in that: The support member (2) is cylindrical, the locking tongue (21) is an elastic sheet body arranged on the support member (2), one end of the locking tongue (21) close to the locking seat (32) is a fixed end (22) connected to the support member (2), and the other end is a free end (23) that always has a tendency to move radially outward away from the support member (2), and correspondingly, the locking seat (32) is a recessed portion formed by a local depression of the inner wall of the storage portion (3).

5. The clamp according to claim 4, characterized in that: A first elastic member (34) is provided inside the receiving portion (3), thereby ensuring that the support member (2) always has a tendency to extend outward along the receiving portion (3).

6. The clamp according to claim 5, characterized in that: The storage portion (3) is provided with a limiting portion (35) at a position facing the opening away from the lock seat (32), and the structure of the limiting portion (35) is consistent with that of the lock seat (32).

7. The clamp according to any one of claims 4 to 6, characterized in that: The transmission mechanism (33) comprises a transmission member (36) in a columnar structure, one end of the transmission member (36) is exposed outside the clamping mechanism (1) to form a trigger portion (37) for a staff member to press, and correspondingly, the storage portion (3) is also provided with a through hole (38) at a position corresponding to the lock seat (32), and the through hole (38) can allow the transmission member (36) to pass through to release the lock tongue (21).

8. The clamp according to claim 7, characterized in that: A second elastic member (39) is arranged between the transmission member (36) and the outer wall of the through hole (38), so that the transmission member (36) always has a tendency to move away from the through hole (38).

9. The clamp according to claim 8, characterized in that: The opening / closing mechanism (13) comprises a bolt (14) and a nut (15), and the bolt (14) is a butterfly bolt and / or the nut (15) is a butterfly nut.
