Description

Work holder

Technical field

The present invention is about a kind of clamping device, and espespecially a kind of replaceable clamping part is to coordinate the different size of thin slice of clamping The work holder of shape workpiece.

Background technology

With making rapid progress for science and technology, the electronic products such as tablet computer, smartphone ... are pursuing what function was promoted Meanwhile also requiring in volume more frivolous to be convenient for carrying and use, therefore need for the micro chip being arranged in electronic product The amount of asking increasingly increases；As shown in Figure 1, micro chip can be a kind of laminar power inductance component W of NR series, has and be separated by Appropriate spacing and side plate W1, the W2 for splitting upper and lower both sides, are equipped with the axle portion of two side plate W1, a W2 of connection between two side plate W1, W2 W3, such power inductance component W must execute the technique of a coiling in the axle portion W3 of two side plate W1, W2, and complete coiling Afterwards, gluing is carried out between two side plate W1, W2 around the technique for being fixed coil online, therefore utilizes four of a clamping device The rectangular power Inductive component W wherein periphery of side plate W2 is clamped in clamping jaw, then provides copper wire and can be wound between two side plate W1, W2 On axle portion W3, or offer glue can be coated on the axle portion W3 between two side plate W1, W2, be a necessary process operation carried out.

Invention content

But traditional clamping device, because Inductive component is made of metal material, therefore the clamping jaw of clamping device is using After a period of time, the clamping face of clamping jaw and side plate peripheral contact is easy clamping device occurs because of abrasion that inductance can not be clamped really The situation of component, and then need replacing new clamping jaw；And Inductive component has different sizes because of specification difference, when to different rule When the Inductive component of lattice is processed operation, also need to replace whole group clamping jaw to meet corresponding specification, the above operation all needs standard Standby multigroup clamping jaw is not only spent the purchase cost of multigroup clamping jaw, is also spent the time cost of clamping jaw dismounting with sharp follow-up replacement.

Therefore, the purpose of the present invention is to provide a kind of work holders reducing clamping jaw replacement cost.

The work holder of purpose according to the present invention, including：One collet chuck, the upper end form several mounting jaws；Several folders Gripping member is detachably mounted on corresponding mounting jaw, to clamping workpiece；One chuck, pivot are placed on the collet chuck upper end, and packet beam should Mounting jaw.

The work holder of the embodiment of the present invention, operating personnel only need to change top bracing member and clamping piece, you can change embedding Width between clip area and depth with the workpiece of corresponding clamping different size, not only dismount it is quick and convenient, also because not needing to change whole group Collet chuck and top bracing mechanism, therefore the cost of purchase can be reduced.
