Abstract

The utility model discloses a milling shift fork end face jig comprising a bottom plate. The bottom plate is fixedly connected with an arc positioning block and a positioning plate. The arc positioning block is provided with an arc side face, the upper surface of the positioning plate is provided with a horizontal positioning face, and the circular arc center of the positioning plate and the circular arc center of the arc side face are located on the same side of the arc side face. The bottom plate is further fixedly connected with a fixing block. The fixing block is in threaded connected with a threaded rod, the threaded rod is arranged along the direction vertical to the positioning plate, the threaded rod is further connected with a sliding block through threads, and the sliding block and the positioning plate are respectively located on two sides of the arc positioning block. According to the milling shift fork end face jig, two movable positioning pins stretching out in the radial direction are added in a positioning circle, so intervals generated due to the fact that an inner circle face of a shift fork is not of a uniform size are eliminated, positional accuracy is improved, and quality of products is stabilized; and in addition, the milling shift fork end face jig further has the advantages of being ingenious in structure, reducing cost, and improving machining efficiency.

Description

Mill shift fork end face anchor clamps
Technical field
The utility model relates to a kind of anchor clamps, particularly relates to a kind of shift fork end face anchor clamps that mill.
Background technology
Shift fork is central very important a kind of part on the automobile gearbox, mainly be to stir shifting slide gear, change its position on gear shaft, gear lever drives declutch shift shaft when the driver promotes gear lever, and declutch shift shaft drives shift fork, realizes different speed thereby shift fork promotes gear again, or be used for clutch in the engineering goods is controlled, such as the structure of end face in conjunction with tooth, the structure of interior external tooth all needs to realize combination and separate with its part of fork controls.Shift fork generally comprises shift fork pawl, declutch shift shaft and shift fork handle, as shown in Figure 1, the flatness of first machined surface (9) on the shift fork pawl and second machined surface (10) on the shift fork handle is had very high required precision.When milling the shift fork end face, adopt the vice holding workpiece usually at present, but this method of clamping instability, and cause processing back retained part distortion easily, and once can only clamping one, working (machining) efficiency is low.
The utility model content
Technical problem to be solved in the utility model is to provide that a kind of clamping is stable, indeformable, efficient is high mills shift fork end face anchor clamps.
The technical solution of the utility model is as follows: a kind of shift fork end face anchor clamps that mill, comprise base plate (1), be fixedly connected with arc locating piece (2) and location-plate (3) on this base plate (1), described arc locating piece (2) has arcuate flanks (2a), the upper surface of described location-plate (3) has horizontal location face (3a), and the center of arc of this location-plate (3) and arcuate flanks (2a) is positioned at the same side of arcuate flanks (2a); Also be fixedly connected with fixed block (4) on the described base plate (1), screw rod (5) has been threaded on this fixed block (4), described screw rod (5) is arranged along the direction perpendicular to location-plate (3), and the sliding shoe (6) that also has been threaded on this screw rod (5), described sliding shoe (6) and location-plate (3) lay respectively at the both sides of arc locating piece (2).
When adopting above anchor clamps holding workpiece, shift fork is placed on the base plate, makes the inner arc surface of shift fork near the arcuate flanks of arc locating piece, the termination of shift fork pawl is placed on the horizontal location face of location-plate.Rotary screw makes sliding shoe move to the arc locating piece along the spiro rod length direction then, finally makes sliding shoe be connected to the end of shift fork.The mode of this method of clamping employing level extruding positions shift fork, is not easy to cause the shift fork distortion in process, and clamping simultaneously is stable, has improved machining accuracy, has promoted product quality.
For the butt that makes sliding shoe and shift fork more stable, described sliding shoe (6) is provided with " U " shape piece (7), this " U " shape piece (7) face relative with arc locating piece (2) be provided with " U " shape groove (7a), and the center line of the center line of this " U " shape groove (7a) and arc locating piece (2) is on same straight line.
Be arranged side by side with two arc locating pieces (2) on the described base plate (1), it is corresponding with two arc locating pieces (2) that the termination, two ends of described sliding shoe (6) is provided with " U " shape piece (7).This structure can be processed two workpiece simultaneously, has improved efficient.
For the levelness of the lower surface that improves shift fork, arcuate flanks (2a) the lower end level of described arc locating piece (2) is the outer eaves (2b) of the level of convexing to form down outwards.
The nut (8) that has been threaded on the described screw rod (5), this nut (8) and sliding shoe (6) lay respectively at the both sides of fixed block (4).After sliding shoe and shift fork connect, twist nut cap, can prevent that sliding shoe from producing displacement in process engineering.
Beneficial effect: the utility model has increased by two radially-protruding loose pins at setting circle, eliminated because the gap of shift fork inner headed face generation not of uniform size, improved positioning accuracy, stablized product quality, also had novel structure, reduce cost, improve characteristics such as working (machining) efficiency.
