Abstract
The utility model discloses a multifunctional clamp. The multifunctional clamp is special for processing a shifting fork of a C6140 lathe headstock and comprises a positioning mechanism, a clamping mechanism and a guiding mechanism. A positioning nail of the positioning mechanism is installed in a hole formed in a clamp body and can be installed and dismounted at any time. Therefore, different specifications of positioning nails can be selected and used according to processing stages, one clamp can adapt to different processing stages, and the number of the clamps is decreased. In addition, the clamping mechanism adopts adjustable supporting screws and nuts, so that the clamping stability is improved. A guiding sleeve of the guiding mechanism is dismounted by adopting a bolt ejection mode, dismounting is convenient, and a using period of a drill bushing is prolonged.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
What the utility model disclosed is a kind of multi-functional clamp, and this fixture is exclusively used in C6140 spindle stock shift fork 1(as shown in Figure 1) processing, as shown in Figures 3 to 6, be preferred embodiment of the present utility model.Described fixture comprises clamp body 2, detent mechanism 3, clamp mechanism 4 and guiding mechanism 5.Wherein:
Coordinate shown in Fig. 7 simultaneously, described clamp body 2 is comprised of a base plate 21 and two risers 22 vertical and that be rigidly attached on this base plate 21, two risers 22 are also mutually vertical, and definition is Z-direction perpendicular to the direction of base plate 21, and the direction perpendicular to two risers 22 is X-direction and Y-direction respectively.On riser 22 perpendicular to X-direction, have an X-direction hole 23, on another piece riser 22, have two Y-direction holes 24.This base plate 21 is provided with a boss 25 for placing Z-direction location-plate 31 described later, on this boss 25, have chip-removal hole 26 and two countersunk head screwed holes 27, this countersunk head screwed hole 27 is for the location and installation of Z-direction location-plate 31, and this chip-removal hole 26 is discharged processing iron filings when holing.On described base plate 21, be also provided with three screwed holes 28, for three bolt and nut groups of follow-up clamp mechanism 4 are installed.
Coordinate shown in Fig. 8 and Fig. 9, described detent mechanism 3 comprises a Z-direction location-plate 31, X-direction locating pin 32 and two Y-direction locating pins 33 simultaneously.This Z-direction location-plate 31 is fixed by screws on the boss 25 of base plate 21 of described clamp body 2.Described X-direction locating pin 32 is plugged on the X-direction hole 23 of described clamp body 2, and described Y-direction locating pin 33 is plugged on the Y-direction hole 24 of described clamp body 2.Described Z-direction location-plate 31 has limited the movement of shift fork Z-direction; Described X-direction locating pin 32 has limited the movement of shift fork X-direction and around the rotation of Y-axis; Described two Y-direction locating pins 33 limited shift fork Y to movement, around the rotation of X-axis with around the rotation of Z axis; This group detent mechanism 3 has limited 6 frees degree of shift fork altogether like this, meets the positioning requirements that adds man-hour.Because described locating pin 32,33 is all that the mode of pegging graft with activity is positioned on clamp body 2, therefore can be according to the difference in the process segments such as thick fine finishining, change the locating pin of different size, so only need a sleeve clamp just can be suitable for different processing stages, the quantity that has reduced fixture, has reduced cost.
