Abstract

The utility model relates to a turn-milling clamp of an axis-withdrawal key slot, which belongs to the technical field of turn-milling clamps. The clamp comprises a baseplate, wherein an upward compressing cylinder is arranged in the middle of the baseplate; a pressure plate is connected to the piston rod of the compressing cylinder, and extended towards the two sides of the piston rod; the pressure plate can lift in a vertical direction under the action of the compressing cylinder; V-shaped positioning blocks are arranged on the two sides of the compressing cylinder corresponding to the lower part of the pressure plate respectively; and each V-shaped positioning block comprises a small V part and a big V part which can be matched with different axis diameters of the axes to be processed. The clamp can finish the key slot processing on different axis diameters of the same axis by only one-time clamping, ensure the requirement for the accuracy of the relative position between two key slots, and can further improve production efficiency, and solve the problems that on one hand, the processing efficiency is lower, and on the other hand, the requirement for the accuracy of the relative position between the two key slots is difficult to be guaranteed in the prior art.

Description

Go out shaft key groove and mill the Vehicle Processing anchor clamps
Technical field
The utility model relates to a kind ofly going out shaft key groove and milling the Vehicle Processing anchor clamps, belongs to the technical field of milling the Vehicle Processing anchor clamps.
Technical background
Keyway is to be used for axle to go up the common structure that plays gearing with other parts, on some axle, often need process keyway at the different diameters of axle position of axle.In the prior art, when the different diameters of axle position on same axle processes keyway, often need to process keyway at different diameter of axle positions respectively through twice, working (machining) efficiency is lower on the one hand for processing mode in this, also is difficult to guarantee relative position precision requirement between two keyways on the other hand.
Summary of the invention
The utility model purpose is to provide clamping of a kind of need can finish the keyway processing that same axle is gone up different diameters of axle position, can guarantee relative position precision requirement between two keyways, and the shaft key groove that goes out that can enhance productivity is milled the Vehicle Processing anchor clamps, it is lower to have solved the one side working (machining) efficiency that prior art exists, and also is difficult to guarantee between two keyways problems such as relative position precision requirement on the other hand.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises base plate, clamping cylinder upwards is set in the middle of the described base plate, be connected with pressing plate on the clamping cylinder piston rod, pressing plate extends to the piston rod both sides, but pressing plate above-below direction lifting under the effect of clamping cylinder; The clamping cylinder both sides are respectively equipped with the V-arrangement locating piece corresponding to the below of pressing plate, and each V-arrangement locating piece has the little V portion and the big V portion that can cooperate with the different diameter of axle portion of processed axle respectively.
Add man-hour, on the V-arrangement locating piece, place a shaft-like work to be processed, the little V portion of the small axle diameter portion of shaft-like work to be processed and vee-block cooperates, large-diameter portion cooperates with big V portion, thereby make the axis of shaft-like work to be processed be in level, promoting pressing plate by clamping cylinder then, to be pressed in the upper surface of axle to be processed tight with axial compression to be processed; Startup milling machine shaft-like work to be processed carries out keyway and mills processing, can process keyway respectively at the different diameters of axle position on the same axle, completion of processing unloads shaft-like work and load onto the axle to be processed of new needs processing, so repeats, realize the continuous processing of milling machine, improved production efficiency.
As preferably, described V-arrangement locating piece is symmetricly set on the both sides of clamping cylinder.
As preferably, described pressing plate lower surface is fixed with two limited posts, and described limited post is corresponding between clamping cylinder and the V-arrangement locating piece.
As preferably, fix by screw between described V-arrangement locating piece and clamping cylinder and the base plate.
As preferably, fix by screw between described pressing plate and the clamping cylinder piston rod end.
As preferably, described base plate is provided with two clamping cylinders that are provided with at interval along the machine direction that mills that mills car, is respectively equipped with the V-arrangement locating piece in the both sides of two clamping cylinders.Add man-hour, shaft-like work to be processed on difference clamping on the V-arrangement locating piece of two cylinder both sides, milling machine at first carries out keyway to the shaft-like work to be processed of one group of anchor clamps clamping wherein and mills processing, the shaft-like work completion of processing for the treatment of this group anchor clamps clamping moves to another group anchor clamps with the milling cutter of milling machine again and mills processing, and the axle that finishes of preceding group of anchor clamps is unloaded and loads onto the shaft-like work to be processed that new needs are processed, so repeat, realized the continuous processing of milling machine, improved production efficiency.
Therefore, only the utlity model has needs a clamping can finish the keyway processing that same axle is gone up different diameters of axle position, can guarantee relative position precision requirement between two keyways, and characteristics such as can enhance productivity.
Description of drawings
Fig. 1 is a kind of clamping structure section schematic diagram of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the machine direction that mills along milling machine in the middle of the base plate 1 is provided with two clamping cylinders that make progress 2 (only expressing among the figure) that are provided with at interval, the upper end of the piston rod 3 of each clamping cylinder alive 2 is provided with the pressing plate 4 that connects by screw with it, pressing plate 4 extends to piston rod 3 both sides, but pressing plate 4 above-below direction lifting under the effect of clamping cylinder 2; Clamping cylinder 2 both sides are symmetrically arranged with V-arrangement locating piece 5 respectively corresponding to the below of pressing plate 4, and each V-arrangement locating piece 5 has the little V portion 6 and the big V portion 7 that can cooperate with the different diameter of axle portion of processed axle respectively.Pressing plate 4 lower surfaces are fixed with two limited posts 8, and limited post 8 is corresponding between clamping cylinder 2 and the V-arrangement locating piece 5, thus limited post 8 lower ends can contact with the upper surface of base plate 1 the restriction pressing plate to down stroke.
Shaft-like work 9 to be processed on the difference clamping on the V-arrangement locating piece, the little V portion of the small axle diameter portion of shaft-like work to be processed and vee-block cooperates, large-diameter portion cooperates with big V portion, thereby make the axis of shaft-like work to be processed be in level, promoting pressing plate by clamping cylinder then, to be pressed in the upper surface of axle to be processed tight with axial compression to be processed; Milling machine at first carries out keyway to the shaft-like work to be processed of one group of anchor clamps clamping wherein and mills processing, the shaft-like work completion of processing for the treatment of this group anchor clamps clamping moves to another group anchor clamps with the milling cutter of milling machine again and mills processing, and the axle that finishes of preceding group of anchor clamps is unloaded and loads onto the shaft-like work to be processed that new needs are processed, so repeat, realize the continuous processing of milling machine, improved production efficiency.
