Description
Technical field
The utility model relates to the location and the clamping of numerical control milling and nc drilling product, the miniature parts that is particularly useful for producing in enormous quantities.
Background technology
In field of machining, workpiece is clamping fast, and the unified together processing of the layout that workpiece can be compact must improve working (machining) efficiency.The a bit deficient on the dense degree of clamping workpiece for some small and exquisite workpiece of processing of traditional vice clamping, volume vice is relatively large because the space of processing platform is limited.The clamping device of small and exquisite practicality just can solve traditional vice big deficiency that takes up room, and the utility model is two faces of the small and exquisite simple but also clamping workpiece pressing of structure not only, and convenient mounting and clamping speed is also fast.
Summary of the invention
The utility model is formed a location and mounting and clamping system by positioning plate, elastomeric element, side pressure chuck and screw.Design has been satisfied: clamp workpiece and will making things convenient for when discharging workpiece, make full use of the arrangement space of workbench, and positioning accuracy will be got well, and can limit the rotation of workpiece and moves, and vibration in the workpiece process and resistance to cutting can find rational support.
The technical scheme that its technical problem that solves the utility model adopts is
1. offer the pressure of workpiece under oblique, effectively controlled moving up and down of workpiece
2. by compressing, effectively prevented workpiece moving horizontally and rotating in anchor clamps in workpiece corner
3. offer the fixture support parts, allow anchor clamps the vibration and stressing conditions under can be stable play a role
4. completion of processing, anchor clamps separate with processing work automatically by elastic part, and next workpiece has also had sufficient gap to put into positioning chamber
5. after workpiece was put into positioning chamber, the side pressure chuck was shifted workpiece onto gulde edge.The anchor clamps that compress in workpiece Jiao Chu two side, pass through positioning plate, elastomeric element, side pressure chuck and screw are formed a location and mounting and clamping system, this system and workpiece have been formed a system that supports mutually, it is characterized in that: the chamber bigger slightly than workpiece profile arranged on the positioning plate, this next door, chamber also has a cavity to be used for placing the side pressure chuck, one countersunk head screw hole is arranged at side pressure chuck top, there is " V " shape angle that contacts with workpiece blank material sidewall the front portion, the bottom of side pressure chuck is all unsettled except that fulcrum, elastomeric elements such as polyurethane or spring are arranged at the bottom of side pressure chuck, and there is the supporting walls of positioning plate at the rear portion
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified
Fig. 1 is the principle sketch
Fig. 2 is the structure chart of the specific embodiment
Fig. 3 is the sketch of many clampings
The specific embodiment
As Fig. 1, what contact with the workpiece right-hand corner is the side pressure chuck, and when clamping workpiece, the upper surface of definition workpiece is last, sees that from top to bottom the front end of side pressure chuck has " V " shape opening.There is one section arc surface the rear end of seeing the side pressure chuck from the side.The face that chuck contacted with workpiece when the side pressure chuck clamped in the ideal case is parallel with the clamped face of workpiece, set forth for convenience and suppose that now the workpiece blank material is a cuboid, the angle that contacts with workpiece of side pressure chuck is the right angle so, press from both sides first downward power with screw to side pressure, the side pressure chuck contacts with workpiece, a fulcrum 1 is arranged at the bottom of side pressure chuck, and there is a fulcrum 2 at the rear portion.The intersection of two faces that the side pressure chuck contacts with workpiece under desirable measuring phase is L1 to the distance of the distal-most end of side pressure chuck, as the last figure of Fig. 1.The rib of the right-hand corner of workpiece is L2 to the distance of side pressure collet rear supporting surface, as figure below of Fig. 1.L1=L2 under the desirable impaction state.Because foozle L1 can not equate with L2.Definition L1 is slightly less than L2, and the side pressure chuck will increase to downward power of workpiece like this, reaches best clamping effect.The place that the side pressure collet rear contacts with fulcrum 2 is designed to circular-arc, and the side pressure chuck can find a fulcrum 2 automatically in the process that certain amplitude is rotated up and down like this.
Several concrete size simulation release process among existing given Fig. 1, as Fig. 1, under desirable measuring phase, given L1=L2=12.79 millimeter, the R=3.5 millimeter, the D=2.0 millimeter, the H=5.17 millimeter, fulcrum 1 is 2.02 millimeters to the distance of side pressure chuck supported back face, make side pressure chuck upper left quarter upwards raise the 1.0-2.0 millimeter now under external force, raising rear fulcrum 1 can move forward, fulcrum 2 can move up, and the minimum clearance that calculates workpiece and side pressure chuck through the CAD moulding is about 0.05 millimeter to 0.08 millimeter, if make L1 be slightly less than L2, then the minimum clearance of workpiece and side pressure chuck can be more bigger, and workpiece can be put into anchor clamps very easily when the side pressure chuck unclamped.
Fig. 2 is the structure chart of the specific embodiment, and placing a workpiece with a positioning plate is example.
As Fig. 2, suppose that the workpiece blank material is a cuboid, material is a carbon steel, side pressure chuck material also is chosen as carbon steel, the bottom is a positioning plate, workpiece is located zero point in the workpiece upper left corner, a chamber bigger slightly than workpiece profile is arranged on the positioning plate, the lower right corner in this chamber has one than the darker cavity in this chamber, be used for placing the side pressure chuck, positioning plate offers the workpiece gulde edge, offer side pressure chuck supporting walls, the side pressure chuck is placed in the cavity of positioning plate, and the gap of flowing for iron filings is arranged about the side pressure chuck and between the cavity of positioning plate, positioning plate is placed the elastomeric element of placing spring or polyurethane material between the bottom of the cavity bottom of side pressure chuck and side pressure chuck, act as to unclamp the side pressure chuck make the up motion automatically of side pressure chuck after the workpiece completion of processing.Provide the cavity of placing elastomeric element below the cavity of placement side pressure chuck, when blowing off iron filings, can not blow out elastomeric element like this.Provide the housing pin hole below the cavity of placement side pressure chuck.Screw sinks to the side pressure chuck, prevents that cutter and screw interfere in process, and the side pressure jaw pressure is supplied with in acting as of screw when tightening, under the effect of elastomeric element the side pressure chuck is pushed open automatically when unclamping.One countersunk head screw hole is arranged at side pressure chuck top, there is " V " shape angle that contacts with workpiece blank material sidewall the front portion, workpiece can be shifted onto the location datum mark, face that contacts with elastomeric element of bottom design, under impaction state, the bottom of side pressure chuck is all unsettled except that fulcrum, and rear design is an arc surface, and the side pressure chuck can find support automatically on the back support wall in the process that certain amplitude is rotated up and down like this.Under impaction state, screw offers the downward power of side pressure chuck, and the side pressure chuck passes to workpiece and positioning plate supporting walls by the structure of oneself, and the rear portion arc surface of positioning plate supporting walls and side pressure chuck contacts, produce small material deformation between line and the face, frictional force strengthens.Positioning plate like this, side pressure chuck and workpiece have been formed one and have been prevented workpiece rotation and the chucking appliance system that moves.
As Fig. 3, a positioning plate can design places many workpiece, improves clamping efficient.
