Summary of the invention
This utility model technology in order to for and solve the problems referred to above, the present invention by by rational technology divide, utilize the method that CNC milling machine is processed, replace the method that numerical control turning is processed, change installation way, improve production efficiency, reduce production cost, it is ensured that product quality.
For achieving the above object, anchor plate SFD number Milling Machining fixture of the present invention, including: base, described base is threaded hole, and base is fixed with workbench by angle gripper shoe;Angle gripper shoe, is connected with base by the way of welding, it is ensured that the axis in processing hole is vertical with platen;Alignment pin, ensures the position in work pieces process hole by the alignment pin on fixture;Hold-down bolt, bolt one end is fixed on bedplate, and other end nut is connected with pressing plate, for workpiece pressing.Anchor plate SFD number Milling Machining fixture, described base, angle gripper shoe, alignment pin are 45# steel, and hold-down bolt, nut are standard component.
This sleeve clamp is made up of, wherein fixture 1 and 2 liang of sleeve clamps of fixture;
Fixture 1 base, alignment pin, fishbolt and angle gripper shoe, utilize the sheet fabrication of modulation 45 steel to make.
Fixture 1 base is with bolt hole, and hold-down bolt is arranged in bolt hole, utilizes nut to make bolt be connected with base 1;
Base becomes 10.5 ° by angle gripper shoe work top, and gripper shoe and base are by being weldingly connected;
With hole, 4 location on clamp body 1 base, by alignment pin location processing workpiece,
Pressing plate is enclosed within bolt, utilizes nut, platen clamp workpiece,
Base can complete the processing of 4 tapered holes of two workpiece simultaneously,
Six faces of base are required for being processed, and are used for cutter, and base plate both sides respectively process the position of an installation pressing plate;
Fixture 1 both can be placed on centering clamping on bench vice, can utilize again pressing plate clamping, flexibility and reliability, convenient mounting and clamping, and fixture 1 can solve tapering inclined hole workpiece two side holes processing and loading clamp.
Fixture 2 includes base, alignment pin, fishbolt and angle gripper shoe, utilizes the sheet fabrication of modulation 45 steel to make.
Fixture 2 base strap bolt hole, hold-down bolt is arranged in bolt hole, utilizes nut to make bolt be connected with base 2,
Base becomes 3.2 ° by angle gripper shoe with work top,
Process the hole, location as the taper hole of workpiece two ends on base, utilize alignment pin that manufactured hole on workpiece is positioned,
Fixture 2 utilizes two workpiece of platen clamp.
CNC milling machine is utilized to position, boring, the taper hole in the middle of processing workpiece,
Later clamping of reversing end for end again has been got well in one hole, processes last middle taper hole.
The effect that the present invention obtains:
1, ensureing machining accuracy, Working position is accurate, and processing technique arranges rationally;
2, clamping is reliable, convenient, and positioning precision is high;
3, fixture is easy to adjust, can use pressing plate clamping, it is also possible to use bench vice clamping, flexibility and reliability.
