The connection shaft is formed by a spring located in the inner hole of the mounting plate; the three-jaw chuck is provided with a plurality of adjustment holes, and a removable adjustment wrench is inserted in the adjustment holes.

The mounting plate is provided with a sheet with an angular reference groove.

The scale on the graduation plate is 0-360°.

The pressing member includes a conical shaft-shaped pressing member and a boss-shaped pressing member.

The pressing member and the three-jaw chuck are on the same axis.

There are at least two T-shaped sliding grooves on the bottom plate, and the seat body and the mounting plate are detachably connected to the bottom plate through bolts.

Knurling is arranged on the limiting member and the handle.

Compared with the prior art, the present invention has the following beneficial effects due to the adoption of the above technical solutions:

The invention has the advantages of simple structure, low cost and convenient operation. The clamping assembly provided with the locking member can clamp and fix the workpiece stably, and the clamping assembly increases the supporting point for the workpiece, so that the workpiece is not easily shaken during the processing. , displacement, which improves the machining accuracy of the workpiece; in addition, the setting of the indexing plate positioning component can effectively prevent the indexing plate from rotating in the process of vibration, so that the angle positioning is more accurate; The size can be changed to improve the general performance of the tooling.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

As shown in Figures 1-2: the multi-functional clamping tool includes a base plate 1, a clamping assembly and a jacking assembly respectively arranged at both ends of the base plate. The jacking assembly consists of a base 2, a top mounted on the base The clamping member 6 and the limiting member 5 for limiting the position of the pressing member are formed. The clamping assembly consists of a mounting plate 12, a three-jaw chuck 8 arranged on one side of the mounting plate, and a three-jaw clamp fastened to the three-jaw clamp. The indexing plate 10 provided with the scale 11 on the plate and attached to the mounting plate 12 , the locking member 18 arranged on the other side of the mounting plate 12 for adjusting and locking the three-jaw chuck 8 , and the indexing plate 10 . The indexing plate positioning assembly for positioning is formed; the indexing plate positioning assembly is composed of a handle 17 and a limit block 22 connected by the connecting shaft 16, a limit post 15 arranged on the handle, sleeved on the connecting shaft 16 and The sleeve 13 provided with the limiting slot 14 and the spring 21 sleeved on the connecting shaft 16 and located in the inner hole of the mounting plate 12 are formed; the three-jaw chuck 8 is provided with a plurality of adjustment holes 9, and the adjustment holes A removable adjustment wrench 7 is inserted. When drilling the workpiece, first tighten the workpiece in the three-jaw chuck 8, then adjust and lock the locking member 18 to prevent the workpiece from moving axially, and then rotate the three-jaw chuck 8 to drive the workpiece to rotate, Adjust the workpiece to the required processing angle, and then push the limit post 15 of the indexing plate positioning assembly into the limit groove 14 of the sleeve 13 to limit the position, so as to prevent the indexing plate 10 from rotating and causing it to fail to be accurately aligned. For a machining point at an angle, finally adjust the base body 2 so that the pressing piece 6 presses the other end of the workpiece, and after tightening the limiting piece 5 to locate the pressing piece, the workpiece can be drilled and other operations.

In order to adjust and limit the angle quickly and accurately, the mounting plate 12 is provided with a sheet 19 with an angle reference groove body 20 . The angle reference groove body 20 is preferably set at 0°, 30°, 45°, 60°, and 90°. If it is not convenient to install the sheet, the groove body with the corresponding angle can also be directly engraved on the mounting plate.

In order to adjust the angle conveniently and accurately, the scale on the indexing plate 10 is 0-360°.

As shown in FIGS. 3 and 4 , in order to expand the versatility of the jacking member so that it can jack workpieces of different sizes, the jacking member 6 includes a conical shaft-shaped jacking member 6-1 and a boss-shaped jacking member 6-1. Tighten 6-2. When the small shaft parts need to be tightened, the conical shaft-shaped clamping member 6-1 is used for clamping, and when the larger surface workpiece needs to be clamped, the boss-shaped clamping member 6-2 is used for clamping. .

The pressing member 6 and the three-jaw chuck 8 are on the same axis.
