Abstract
The invention discloses a clamp for milling grounding contacts of a high voltage rotation isolating switch. The clamp comprises a geometrical shell (1) of which the upper part is provided with a plurality of grooves matched with the shapes of processing workpieces, wherein two sides of the outer surface of the shell (1) are fastened with a plurality of brackets (4) which are hinged with pressing plates (2), and simultaneously the pressing plates (2) are connected to the shell (1) through a spring (3); the lower part of the corresponding bracket (4) on the shell (1) is provided with a plurality of guide sleeves (5) which are provided with guide pins (6) therein; a rotating shaft (10) provided with a plurality of cones (11) are fixed in the shell (1); one end of the guide pin (6) is pressed on the cone, while the other end is supported against the bottom of the pressing plate (2); and the end part of the rotating shaft (10) is provided with adjusting nuts (14). The milling clamp is convenient to assemble, can mill a plurality of the grounding contacts at the same time, and has convenient processing and high quality.
Description
Technical field
The present invention relates to a kind of milling machine clamp for machining, particularly a kind of high-pressure rotary isolating-switch earth-contact milling clamp.
Background technology
In electrical power distribution system, contact knife closed on the grounding contact when high voltage rotary isolation switch disconnected, and contact knife is in ground state when making disconnection, prevented that it is accidental closed, improves safety coefficient.Grounding contact is the important component part that high-pressure rotary is left the pass.Because its T shape structural limitations, the face that clamps is less, and used bench vice is difficult for clamping during general milling machine processing grounding contact, and deflection takes place easily, and once can only workpiece of clamping, and efficient is low, uses inconvenient.
Summary of the invention
The objective of the invention is to design a kind of convenient mounting and clamping, high voltage rotary isolation switch grounding contact milling machine clamp for machining that working (machining) efficiency is high.
Technical scheme of the present invention is: anchor clamps of the present invention comprise an a few shape frame case, and a plurality of grooves that match with the processing work profile are arranged at top, are used to clamp grounding contact; The housing outer surface both sides are fastened with some supports, are hinged with L shaped pressing plate on the support, and pressing plate is connected on the housing by spring simultaneously, housing upper bracket bottom correspondence is provided with some fairleads, in guide finger is arranged, the corresponding grounding contact of pressing plate forms the device of a plurality of workpiece pressings; Enclosure interior firmly has a rotating shaft, and some cones are arranged in the rotating shaft, and guide finger one end withstands on the cone, and the other end withstands the pressing plate bottom; The roller end threaded engagement has the adjustment nut.
During use, place a plurality of grounding contacts in groove, screw nut, cone moves together with axle, and cone promotes guide finger and moves, and holds out against the pressing plate bottom, makes pressing plate top workpiece pressing, the anchor clamps housing is fixed on the milling machine just can processes a plurality of grounding contacts simultaneously.Not only guarantee crudy, and improved working (machining) efficiency.
By changing the profile of housing upper slot, can also be used to process other workpiece.
Milling machine clamp for machining convenient mounting and clamping provided by the invention can be processed a plurality of workpiece, the working (machining) efficiency height simultaneously.
Description of drawings
Fig. 1 is the structural representation of an embodiment of high-pressure rotary isolating-switch earth-contact milling clamp of the present invention;
Fig. 2 is the A-A cross-sectional view of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Among the figure: 1, housing 2, pressing plate 3, spring 4, support 5, fairlead 6, guide finger 7, fairlead 8, fixed head 9, guide pin 10, rotating shaft 11, cone 12, fixed head 13, stop collar 14, nut 15, pin 16, grounding contact
As shown in the figure, housing 1 is an a few shape framework, and a plurality of grooves that match with the processing work profile are arranged at top, are used to clamp grounding contact 16; Housing 1 outer surface both sides are fastened with some supports 4, be hinged with L shaped pressing plate 2 by pin 15 on the support 4, pressing plate 2 is connected on the housing 1 by spring 3 simultaneously, housing 1 upper bracket 4 bottom correspondences are provided with some fairleads 5, in guide finger 6 is arranged, guide finger 6 one ends withstand pressing plate 2 bottoms, and pressing plate 2 corresponding grounding contacts 16 form the device of a plurality of workpiece pressings; Firmly there is a rotating shaft 10 at housing 1 inner two ends by fixed head 8, fairlead 7 and fixed head 12 respectively, and rotating shaft 10 1 ends have a stopper slot, and some cones 11 are arranged in the rotating shaft 10, and guide finger 6 other ends withstand on the cone 11.Guiding 7 puts the guide pin 9 that cooperates with stopper slot.Rotating shaft 10 end thread are combined with nut 14, and nut 14 outsides are provided with stop collar 13.
Simultaneously a plurality of grounding contacts 16 are placed in the groove on housing 1 top, screw nut 14 drive axles 10 and move, make cone 11 compress guide finger 6, make pressing plate 2 compress grounding contact 16, anchor clamps housing 1 is fixed on the milling machine and can mills system to workpiece.
