Clamping and positioning system

Abstract

A clamping and positioning system includes a base and at least one clamping member. The base has at least one recessed receiving groove, and a plurality of fixing holes are formed around the receiving groove in a ring shape. The base has a first channel, a second channel, and a third channel that are laterally connected. A first side flow channel and a second side flow channel are recessed in the receiving groove and are located between the fixing holes. The base has at least one first connecting hole that connects the first side flow channel and the first channel in a longitudinal direction. The clamping member includes a base, a plurality of springs, a spring limiting seat, and a top cover. A spring is disposed between the bottom hole and the top hole of the spring to push against the spring limiting seat. The top cover communicates with the spring limiting seat and the first side flow channel. The base communicates with the spring limiting seat and the second side flow channel. The groove communicates with the second connecting hole.

Claims

1. A clamping and positioning system comprising a base and at least one clamping member, wherein: The base is recessed with at least one receiving groove, and the base is circumferentially provided with several fixing holes around the receiving groove. The base is laterally connected with a first channel, a second channel, and a third channel. The receiving groove is recessed outward with an arc-shaped first side flow channel and an arc-shaped second side flow channel. The first side flow channel and the second side flow channel are located between the fixing holes and completely avoid the fixing holes. The base is longitudinally provided with at least one first connecting hole to connect the first side flow channel and the first channel. The top opening of the first connecting hole is blocked and closed by a sealing element. The bottom of the receiving groove is longitudinally provided with at least one second connecting hole to connect with the second channel. The second side flow channel is connected with the third channel. The clamping component includes a base, several springs, a spring limiting seat, a top cover, and a clamping part. The top of the base has a recessed and annular arrangement of several spring bottom holes, and the bottom of the base has a recessed groove. A platform is convex upward at the center of the base, and the platform has a recessed groove that communicates with the groove. The bottom of the spring limiting seat has a recessed spring top hole corresponding to the position and number of the spring bottom holes. A spring is disposed between the spring bottom hole and the spring top hole to push against the spring limiting seat. The clamping part is disposed in the center of the top cover. The top cover abuts against the opening of the receiving groove and is screwed into the fixing hole by several screws. The surface of the clamping part is provided with a locking groove. A number of beads are disposed between the base, the spring limiting seat, the top cover, and the clamping part to engage with the locking groove. The top cover communicates with the spring limiting seat and the first side flow channel. The base communicates with the spring limiting seat and the second side flow channel. The groove communicates with the second connecting hole.

2. The clamping and positioning system as described in claim 1, wherein, The spring includes an outer spring and an inner spring. The outer spring and the inner spring are coaxially arranged and their helical directions are opposite. The outer springs in adjacent bottom holes of the springs have opposite helical directions, and the inner springs in adjacent bottom holes of the springs have opposite helical directions.

3. As in request item 1, the clamping and positioning system, wherein, The screw-on device includes a screw and a top plate. The screw passes through the top plate and is screwed into the fixing hole. The top plate is fixed to the top of the screw to make its surface flat.

4. The clamping and positioning system as described in claim 1, wherein, The clamping component is provided with several airtight rings to increase airtightness.

5. The clamping and positioning system as described in claim 1, wherein, The bottom hole and the top hole of the spring are arranged in a ring and concentrically set with any number of turns.

6. The clamping and positioning system as described in claim 1, wherein, The plurality of springs can be coaxially disposed between a bottom hole and a top hole of the spring.

7. The clamping and positioning system as described in claim 1, wherein, The spring bottom holes are six in number and are symmetrically and evenly distributed on the base.

8. The clamping and positioning system as described in claim 1, wherein, The top inner side of the spring limiting seat is provided with a first chamfered surface and a second chamfered surface with different slopes.
