Description

Clamping structure for centrifuge adapter

Technical Field

The utility model relates to an automatic change centrifuge's adapter clamping part's among centrifugal system structural design.

Background

The centrifugal machine is used for separating matter, belongs to basic laboratory equipment and is used widely in life science, medicine, chemistry, environment protection and other fields. Along with the development of the market, the recruitment is more and more difficult and the manual operation is easy to make mistakes, and all hospitals need a full-automatic centrifugal system to replace the manual operation so as to improve the efficiency. The handle on the original adapter of centrifuge is that the plain noodles does not have the friction, and manipulator finger centre gripping adapter's dynamics is big, and long-term application has the influence and the structure also can be influenced to the performance of manipulator, and when cutting off the power supply suddenly, the manipulator finger does not have clamping-force, and a whole set of adapter structure will drop automatically, pounces bad part.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome not enough and the defect mentioned in the above background art, provide the tight structure of clamp that a centrifuge adapter was used to improve the security performance.

In order to solve the technical problem, the utility model provides a technical scheme does:

the utility model provides a press from both sides tight structure that centrifuge adapter was used, press from both sides tight structure and include anchor clamps, set up at the terminal clamping piece of anchor clamps bottom to and the adapter handle, terminal clamping piece inside surface is equipped with a plurality of first recesses, adapter handle outside surface is equipped with a plurality of annular second recesses, and the second recess endotheca is equipped with the sealing washer, and is pressing from both sides tight state the sealing washer is by partial card in first recess.

Furthermore, the tail end clamping piece is fixedly connected with the clamp through a screw.

Furthermore, the tail end clamping piece is provided with two symmetrical pieces, and the adapter handle is clamped between the two pieces in a clamping state.

Furthermore, the tail end clamping piece is cylindrical, and the section of the tail end clamping piece is a sector ring or a part of a ring.

Further, the first groove is circumferentially arranged on the inner side surface of the tail end clamping piece from top to bottom.

Furthermore, the first groove is matched with the outer diameter of the sealing ring.

Further, the second groove is arranged on the outer side surface of the adapter handle from top to bottom along the circumferential direction.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a fluting installs sealing washer structure additional on the adapter handle, and the inner face design of terminal clamping piece is cell type flank of tooth form, and the sealing washer is in clamping state and flank of tooth cooperation, increases its surface friction like this, and the difficult pine of adapter takes off when the manipulator moves, even if the power-off anchor clamps lose clamping-force, and gravity can be offset completely to frictional force, keeps the clamping state before the outage, and the adapter also can not drop, has improved a whole set of centrifugal system's security performance to improve degree of automation. Due to the fact that friction force is increased, even if the strength of clamping the adapter by fingers of the manipulator is high, the performance of the manipulator and the structure of the adapter cannot be affected after long-term operation.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the following specific embodiments.

Unless otherwise defined, all terms of art used hereinafter have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the present invention.

As shown in fig. 1, the clamping structure for an adapter according to the embodiment of the present invention includes a clamp 1, a terminal clamping piece 3 and an adapter handle 5, the terminal clamping piece 3 and the clamp 1 are disposed at the bottom end of the clamp 1, and the terminal clamping piece 3 and the clamp 1 are fixedly assembled by a screw 2.

As shown in fig. 1, the end clip 3 has two pieces which are bilaterally symmetrical. In use, the adapter handle 5 is sandwiched between the two pieces. Referring to fig. 3-5, the end clip 3 is cylindrical, has a sector ring or annular section, and has a plurality of first grooves formed in the inner surface of each clip along the circumferential direction from top to bottom to form a groove-shaped tooth surface.

As shown in fig. 2, a plurality of annular second grooves are circumferentially arranged on the outer surface of the adapter handle 5 from top to bottom, and a plurality of sealing rings 4 are sleeved in the second grooves and are tightly matched with the adapter handle 5.

When the clamp 1 operates to clamp the handle 5 of the adapter, the first groove on the terminal clamping piece 3 is matched with the outer diameter of the sealing ring 4, so that the friction force is increased, and the clamping action is stable.

The utility model discloses a processing method: fix terminal clamping piece 3 to anchor clamps 1 earlier, fix a position with the locating pin earlier, reuse M4's hexagon socket head cap screw is fixed, each 1 piece in both sides, the sealing washer 4 is gone into the inslot of adapter handle 5 with professional instrument card, all need the card all around to go into the inslot, fix anchor clamps 1 to robotic arm, on the whole set of assembly of adapter was accomplished and is placed the workstation, whole set of system during operation, the manipulator can automatic centre gripping and release adapter handle 5, cooperates the operation of whole set of automatic system.

The foregoing is illustrative of the preferred embodiment of the present invention and is not to be construed as limiting the invention in any way. Therefore, any simple modification, equivalent change and modification made to the above embodiments by the technical entity of the present invention should fall within the protection scope of the technical solution of the present invention.
