Block is compressed and is positioned over processing workpiece on the jig, at this moment the jig, processing workpiece, briquetting, screw rod, first
The balance of power is reached between chuck pipe, the second chuck pipe, processing workpiece is fixed on the jig.
Preferably, the inner nut inner surface setting has screw thread corresponding with the screw rod, and outer surface is provided with groove, described
Antislip ring is installed in groove, can so increase rubbing between the inner nut and the second chuck pipe top borehole jack inwall
Power is wiped, prevents the inner nut from coming off from the borehole jack.
Preferably, the briquetting baseplane is provided with cruciform groove, can so block the bossing of processing workpiece,
Effectively improve workpiece stability in process.
Preferably, the material of the briquetting is No. 45 steel.
By above-mentioned technical proposal, this utility model is inserted on the jig different by the first chuck pipe
Location hole in and the first chuck pipe can realize that processing workpiece exists with the transfer of the second chuck pipe relative position
Position adjustments on the jig, the apparatus structure simply greatly reduces production cost, and the device is easy to operate, practical
Property it is strong, substantially increase work efficiency.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
This utility model is described in further detail with reference to embodiment and specific embodiment.
As shown in Figure 1 and Figure 2, a kind of Quick-positioning clamp, including jig 1, the first chuck pipe 2, the second chuck pipe 3,
Screw rod 4, inner nut 5, briquetting 6 and spacing collar 7;The jig 1 is provided with multiple location holes 9, and the location hole 9 is blind
Hole, the top of the first chuck pipe 2 is provided with borehole jack, and the bottom of the first chuck pipe 2 is inserted in the positioning of the jig 1
In hole 9, described one end of second chuck pipe 3 is provided with borehole jack, and the other end is steel cylindrical tube, and the second chuck pipe 3 is inserted in
In the borehole jack at the top of the first chuck pipe 2, the inner nut 5 is built in the borehole jack of the second chuck pipe 3, the screw rod
4 are placed through in the inner nut 5, and the top of the screw rod 4 is hexagon cylinder, and upper surface is provided with hexagonal indentations, described
The bottom of screw rod 4 is bulb 8, and the top of the briquetting 6 is provided with groove corresponding with the bulb, and the bulb 8 is inserted in described
In groove, the bulb 8 is provided with spacing collar 7 with the junction of the groove.The device by turn the screw rod 4 make it is described
Briquetting 6 compresses the processing workpiece being positioned on the jig 1, at this moment the jig 1, processing workpiece, briquetting 6, spiral shell
The balance of power is reached between bar 4, the first chuck pipe 2, the second chuck pipe 3, processing workpiece is fixed on the jig 1.
The inner surface setting of the inner nut 5 has and the corresponding screw thread of the screw rod 4, and outer surface is provided with groove, the groove
Antislip ring is inside installed, can so increase the friction between the inner nut 5 and the top borehole jack inwall of the second chuck pipe 3
Power, prevents the inner nut 5 from coming off from the borehole jack.
The baseplane of the briquetting 6 is provided with cruciform groove, can so block the bossing of processing workpiece, effectively
Improve workpiece stability in process.
The material of the briquetting 6 is No. 45 steel.
By above-mentioned technical proposal, this utility model is inserted on the jig 1 not by the first chuck pipe 2
With location hole in and the first chuck pipe 2 can realize processing work with the transfer of the relative position of the second chuck pipe 3
Part on the jig 1 position adjustments, the apparatus structure simply greatly reduces production cost, the device operation side
Just, it is practical, substantially increase work efficiency.
Above-described is only a kind of Quick-positioning clamp preferred implementation of the present utility model, it is noted that for
