Detailed Description
The invention is further described with reference to the following specific drawings and examples.
As shown in fig. 1-4: the embodiment discloses an assembling tool clamp with a mistake proofing function, which is characterized by comprising a wrench body 1, a screw 3, a nut 4 and a mistake proofing cushion block 2;
the inner wall of the wrench body is fitted with a mistake-proofing cushion block 2, corresponding positions of the mistake-proofing cushion block 2 and the wrench body are both provided with threaded holes, screws 3 are assembled in the threaded holes, and the end parts of the screws 3 are assembled and connected through nuts;
the mistake-proofing cushion block 2 is of a structure provided with a stepped hollow round table cavity, and comprises a first part 2.1 and a second part 2.2 which are integrally formed,
the first part is of an annular structure, the outer surface of the first part is in a hexagon shape matched with the inner wall of the wrench body, and a first cylindrical cavity 5 is formed inside the first part;
the second part is of an annular structure, the outer surface of the second part is a cylinder matched with the inner wall of the wrench body, and a second cylinder cavity 6 is formed inside the second part;
as a further improvement of the utility model, the inner diameter of the first cylindrical cavity 5 is larger than that of the second cylindrical cavity 6;
and the screw holes formed in the anti-dislocation cushion blocks extend into the second cylindrical cavity 6 along the radial direction.
As a further improvement of the present invention, the screw 3 is a hollow structure.
Wherein:
h1-height of thread at the assembling end of assembling screw 5 and product 6;
h2-the height of the screw thread at the assembling end of the assembling screw 5 and the anti-dislocation cushion block 2;
h3-thickness of hexagonal step of assembly screw 5;
h4-thickness of the first part 2.1 of the mistake proofing mat 2;
h5-thickness of the second part 2.2 of the mistake proofing mat 2;
h6-height of wrench body slot;
this design is suitable for both error-proof cases of the screw.
The first condition is as follows: as shown in fig. 2, a screw with the same specification and different length at two ends, H1> H2, ensures that H4 is higher than the height of the end (i.e., H2) of the screw to be assembled with the screw, but lower than the height of the other end (i.e., the end to be assembled with the product 6) (i.e., H1); the other is that the two ends have different specifications but the nominal size is the same (for example, one end is provided with an R thread, and the other end is provided with a G thread), and the situation is only that the diameter of the end, which is larger than the end of the screw to be assembled with the end, is smaller than the major diameter of the other end.
Case two: as shown in fig. 3, when the specifications of the two ends of the assembly screw are the same but the lengths are different, when H1 is smaller than H2, a slot is required to be formed on the wrench body, the slot is formed at a position corresponding to the hexagon of the assembly screw, the diameter of the slot is larger than the diameter of the circumscribed circle of the hexagon of the assembly screw, the height H6 of the slot is larger than the thickness H3 of the step of the hexagon, and at this time, if the H1 end is installed incorrectly, the wrench is not forced; when the height H6 of the groove is smaller than the thickness H3 of the hexagonal step, it can be applied to the case where H1 is larger than H2.
A mistake-proofing cushion block 2 is additionally arranged in a concave structure of a socket wrench 1 of a screw to be assembled, the fall value from the mistake-proofing cushion block 2 to the end face of the socket wrench 1 is well controlled, if the assembling direction of the screw to be assembled is reversed, a socket wrench cannot bear on a joint to be assembled, namely, the assembling tool clamp cannot assemble the screw to be assembled into a specified threaded hole. In order to connect together mistake proofing cushion 2 and box spanner 1 and quick detachable, need carry out structural improvement to assembled standard box spanner 1, increase the screw hole on the external diameter surface, mistake proofing cushion 2 is installed standard box spanner 1 back, also has the screw hole of a same specification with standard box spanner 1 in same direction of height, adopts screw 3 and nut 4 to connect standard box spanner 1 and mistake proofing cushion 2 and finally fix.
Owing to receive sleeve circumference torsion's the reason, the contact vestige of slight degree of depth easily appears in product 6's terminal surface to influence the outward appearance of product, the utility model discloses because the existence of inside mistake proofing cushion, telescopic terminal surface can not direct contact again with the terminal surface of product and have certain clearance, can effectively avoid the contact vestige.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solution of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
