Background
The watchcase of production wrist-watch need carry out the cutting processing completion on the lathe, because the structure is less, and the machining precision requires highly, and ordinary anchor clamps can't satisfy the requirement, if when specifically add man-hour, because discoid by the centre gripping always meet the inhomogeneous problem of clamping-force, add man-hour at centre gripping watchcase spare, because the clamping-force is inhomogeneous, the axial force that leads to processing arouses watchcase surface to produce deformation, influences the processingquality of work piece, and the anchor clamps structure to the watchcase of current design is complicated relatively, and is with high costs.
disclosure of Invention
An object of the utility model is to provide a watchcase precision clamping device adopts simple structure can accomplish the centre gripping to the wrist-watch watchcase of small-structure.
The utility model adopts the technical proposal that: the utility model provides a precision clamping device of watchcase, includes base plate, adsorption plate, it has first recess to open on the base plate, the adsorption plate cap seals and forms a cavity air chamber on the first recess of base plate, the side of base plate is equipped with the aspirating hole that accesss to the air chamber, the upper surface of adsorption plate is equipped with the second recess that a plurality of matches the watchcase profile, second recess bottom is equipped with the cyclic annular bar groove of a plurality of intercommunication each other be equipped with the air vent that accesss to the air chamber on the cyclic annular bar groove.
Wherein, be equipped with a plurality of screw hole that runs through to the base plate around the adsorption plate, the adsorption plate covers with bolt-up connection with the base plate and seals.
And the positions of the adsorption plate and the upper cover seal of the base plate are provided with an annular seal groove and a sealing rubber strip placed in the annular seal groove.
And an avoiding groove connected to the second groove is further formed in the upper surface of the adsorption plate.
Wherein, the side of base plate still is provided with balanced gas pocket.
Compared with the prior art, the utility model has the following advantage: the utility model discloses a precision clamping device of watchcase, the second recess through matcing the watchcase profile on the adsorption plate is used for prescribing a limit to the position of watchcase at the horizontal plane, makes the watchcase keep can not all around on the horizontal plane removal, covers with the base plate of taking first recess and adsorption plate simultaneously and closes and form a cavity air chamber to the aspirating hole that accesss to the air chamber that sets up in the side of base plate is as airflow channel. The air chamber is pumped to form internal and external pressure difference, the bottom of the second groove is provided with a plurality of annular strip-shaped grooves which are communicated with each other, and the annular strip-shaped grooves are provided with air vents leading to the air chamber, so that the watchcase placed on the second groove is isolated from the internal air chamber to form the internal and external pressure difference, the surface of the watchcase forms uniform and adjustable pressure, the watchcase is limited to be tightly attached to the adsorption plate, the processing of the watchcase is facilitated, and the whole clamping device is simple in structure, stable and reliable.
Drawings
Fig. 1 is a schematic view of the exploded structure of the present invention.
Fig. 2 is a schematic perspective view of the present invention.
The numbers in the figure are shown as 1-a base plate, 11-a first groove, 12-an air extraction hole, 13-a balance air hole, 2-an adsorption plate, 21-a second groove, 22-a strip groove, 23-an air vent, 24-an avoiding groove, 3-an annular sealing groove and 4-a sealing rubber strip.
The specific implementation mode is as follows:
In order to enhance the understanding of the present invention, the following detailed description will be made in conjunction with the embodiments and the accompanying drawings. The utility model discloses the accessible is implemented as follows:
Referring to the precise clamping device for the watchcase shown in fig. 1 and 2, the precise clamping device comprises a base plate 1 and an adsorption plate 2, wherein a first groove 11 is formed in the base plate 1, the adsorption plate 2 covers and seals the first groove 11 of the base plate 1 to form a cavity air chamber, an air suction hole 12 leading to the air chamber is formed in the side surface of the base plate 1, and an internal and external air pressure difference is formed by sucking air into the air chamber. The upper surface of the adsorption plate 2 is provided with a plurality of second grooves 21 matched with the outline of the watchcase, and the watchcase to be processed is placed in the second grooves 21 to limit the fixed position of the watchcase in the plane of the adsorption plate 2. The bottom of the second groove 21 is provided with a plurality of annular strip-shaped grooves 22 which are communicated with each other, the annular strip-shaped grooves 22 are provided with vent holes 23 leading to the air chamber, the meter shell at the plane position is limited by the second groove 21, and the surface of the adsorption plate 2 is further clung to the inside and outside pressure difference formed by air suction of the air chamber, so that the effect of stable clamping is achieved, and the whole device is simple in structure, stable and reliable.
Wherein, adsorption plate 2 is equipped with a plurality of screw hole that runs through to base plate 1 all around, adsorption plate 2 and base plate 1 are with bolt-up connection to carry out the lid and seal.
