Abstract
The utility model provides a fastening chuck for a double-thread screw. The fastening chuck for the double-thread screw comprises a cylindrical body, wherein a blind hole is formed in one end of the cylindrical body, internal threads matched with external threads of the double-thread screw are formed in the blind hole so that the double-thread screw can be connected with the blind hole, the thickness of the outer surface of the end, with the blind hole, of the cylindrical body progressively increases in the grooving direction, external threads are formed in the outer surface of the end, with the blind hole, of the cylindrical body, a hexagon nut matched with the external threads formed in the surface is arranged at the end, with the blind hole, of the cylindrical body, and a hexagon extending portion is arranged at the other end of the cylindrical body. According to the scheme, the fastening chuck serves as an auxiliary device for fastening the double-thread screw, the defects that when a nut of a double-thread screw is fastened, the double-thread screw rotates along with the nut, and fastening cannot be carried out can be effectively overcome, fastening operation can be carried out by using a pneumatic tool so that the degree of fatigue of operators can be reduced, and installing efficiency is greatly improved.
Description
Technical field
The utility model relates to field of mechanical technique, refers to especially a kind of mounting bracket of double threaded screw.
Background technology
In the time that automobile is tested, need to carry out clamping to vehicle, now need vehicle jaw bearing to be fixed on testing stand.Wherein the vehicle of separate frame construction cannot directly directly clamp with opening bench vice, needs first vehicle crossbeam and upper grip to fix installation with lower bench vice interlock again after by double end long bolt and its fastening nuts.But in to the fastening process of double threaded screw and nut thereof, double threaded screw can be with being rotated by nut, and causing cannot be fastening to it.Because screw rod two ends are screw thread, cannot use pneumatic tool simultaneously, cause installment work efficiency low.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure and double threaded screw mounting bracket that can increase work efficiency, and the fastening of double threaded screw and nut helped out.
In order to address the above problem, the utility model embodiment has proposed a kind of mounting bracket, comprise cylindrical body, described cylindrical body one end is provided with blind hole, in described blind hole, be provided with the internal thread suitable with the external screw thread of described double threaded screw to be connected described double threaded screw, described cylindrical body blind hole end outer surface thickness is along fluting direction thickening be provided with external screw thread gradually, and described cylindrical body blind hole end is provided with the hex nut matching with surperficial external screw thread; And the other end of described cylindrical body is provided with a hexagonal extension.
Wherein, described cylindrical body is provided with the through hole that runs through described cylindrical body along diametric(al).
Wherein, described cylindrical body is evenly distributed with two or more the axially extended fluting along described cylindrical body that is provided with on the tube wall of the correspondence position of described blind hole.
Wherein, described fluting is 4 to 6.
Wherein, described cylindrical body blind hole end outer surface thickness is along fluting direction thickening gradually.The beneficial effect of technique scheme of the present utility model is as follows:
The mounting bracket of such scheme is as the fastening auxiliary equipment of double threaded screw, not only can effectively eliminate the nut of fastening double threaded screw time, screw rod rotates drawback that cannot be fastening thereupon, and can solve the problem that double threaded screw two ends cannot clamp, thereby can reduce the tired degree of operating personnel and significantly improve installation effectiveness by carry out fastening operation with pneumatic tool.

The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model, for the fastening difficulty of existing double threaded screw and the low problem of installation effectiveness, proposed a kind of mounting bracket, and its structure as shown in Figure 1, comprises cylindrical body 1; As shown in Figure 4, described cylindrical body 1 one end is provided with blind hole 2, in described blind hole 2, be provided with the internal thread suitable with the external screw thread of described double threaded screw to be connected described double threaded screw, described cylindrical body is provided with the hex nut 3 matching with its blind hole end surfaces external screw thread.
As shown in Figure 1, be provided with a hexagonal extension 4 at the other end of described cylindrical body 1.As shown in Figure 1 and Figure 2, described cylindrical body 1 is provided with the through hole 5 that runs through described cylindrical body 1 along diametric(al).As shown in Figure 1, Figure 2, Figure 4 shows, described cylindrical body 1 is evenly distributed with two or more the axially extended fluting 6 along described cylindrical body that is provided with on the tube wall of the correspondence position of described blind hole 2, and its fluting direction A as shown in Figure 1 and Figure 2.Wherein, this fluting can be 4 to 6; Wherein as shown in Figure 4 for having adopted the structure of 6 flutings.Wherein, described cylindrical body blind hole end outer surface thickness is along fluting direction thickening gradually.
The extension 4 of the mounting bracket of the utility model example can use standard openings spanner and Pneumatic sleeve instrument to operate, and hex nut 3 can use standard openings spanner to operate, so that increase work efficiency.On cylindrical body 1, be provided with through hole 5, so just can utilize instrument to be inserted in through hole 5 and reduce operating physical force to increase arm of force length increase Tightening moment simultaneously.The end of described device has four to six notches, end face is in an inverted cone, can utilize like this instrument and by fastening hex nut 3 by the locking that is spirally connected of the blind hole end of described device and double threaded screw end, thereby double threaded screw is become " single-head screw ", the drawback that when fastening to eliminate, screw rod also rotates thereupon, and pneumatic tool is fastening increases work efficiency by using.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
