Description
Technical Field
The utility model relates to the technical field of automobile manufacturing, in particular to a tool for bolt connection and installation.
Background
In the vehicle assembly process, particularly the number of connecting bolts on the vehicle frame is very large, and the bolt tightening process usually needs to back tighten the bolt head (or nut) and then tighten the nut (or bolt head) with a wrench. In fact, many bolts are closely spaced, the position of the bolt is inconvenient to operate, a wrench cannot be operated, or an operator tightens one end of the bolt with a wrench and using a structure, and the wrench is difficult to be seized and removed after the bolt is tightened.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the background art, the utility model provides a tool for bolt connection installation, which aims to solve the problems of inconvenience, time and labor waste and low efficiency of bolt connection installation operation in the prior art.
The purpose of the utility model is realized by the technical scheme, which comprises the following steps:
a tool for bolt connection installation is characterized in that: comprises a pull rod, a pulling hammer and a nut; the pull rod consists of a wedge-shaped section, a round rod section and a screw section which are sequentially connected from left to right; the center of the drawing hammer is provided with a through hole, the through hole extends along the axial direction of the drawing hammer, the diameter of the through hole is matched with that of the round rod section, the drawing hammer is sleeved on the round rod section through the through hole, and the drawing hammer can slide back and forth on the round rod section; the wedge-shaped section comprises 2 inclined planes which are arranged at an included angle, the opening direction of the included angle of the 2 inclined planes is arranged towards the right, and the maximum radial size of the right end of the wedge-shaped section is larger than the outer diameter size of the through hole; the nut is sleeved on the screw rod section, and the maximum radial dimension of the nut is larger than the radial dimension of the through hole.
Furthermore, a counter bore is arranged at the right end of the through hole, and the diameter of the counter bore is larger than the maximum radial dimension of the nut.
Further, the included angle of 2 inclined planes is 10 degrees.
Due to the adoption of the technical scheme, the utility model has the following advantages: because the wedge-shaped section can be used for back tightening between the two bolt heads (or nuts) which are close to each other, after the bolt is tightened, the wedge-shaped section can be withdrawn from between the two bolt heads (or nuts) by using the pulling hammer, so that the operation is convenient, the time and the labor are saved, and the production efficiency is greatly improved.
Drawings
The drawings of the present invention are described below.
FIG. 1 is a schematic structural diagram of the present invention.
In the figure: 1. A pull rod; 2. pulling a hammer; 3. a nut; 4. a bolt pair; 11. a wedge-shaped section; 12. a round bar section; 13. a screw section.
Detailed Description
The utility model is further illustrated by the following figures and examples.
The tool for bolt connection installation shown in figure 1 comprises a pull rod 1, a pulling hammer 2 and a nut 3; the pull rod consists of a wedge-shaped section 11, a round rod section 12 and a screw section 13 which are sequentially connected from left to right; a through hole is formed in the center of the drawing hammer 2, the through hole extends along the axial direction of the drawing hammer 2, the diameter of the through hole is matched with that of the round rod section 12, the drawing hammer 2 is sleeved on the round rod section 12 through the through hole, and the drawing hammer 2 can slide back and forth on the round rod section 12; the wedge-shaped section 11 comprises 2 inclined planes which are arranged at included angles, the included angle of each of the 2 inclined planes is 10 degrees, the opening direction of the included angle of each of the 2 inclined planes is arranged towards the right, and the maximum radial size of the right end of the wedge-shaped section 11 is larger than the outer diameter size of the through hole; nut 3 suit is in on screw rod section 13, nut 3's maximum radial dimension is greater than the radial dimension of through-hole.
In order to reduce the overall length of the tool and save the operating space, a counter bore is arranged at the right end of the through hole, and the diameter of the counter bore is larger than the maximum radial dimension of the nut 3.
As shown in fig. 1, the member 4 is a bolt head of 2 bolt pairs to be screwed, before screwing, the wedge-shaped section 11 is firstly inserted between the two bolt heads 4, when a nut of one of the bolt pairs is screwed, the two bolt heads simultaneously press the wedge-shaped section, so that the wedge-shaped section forms a reverse moment (namely, a commonly-known back tightening force) on the screwed bolt head, and when the screwing moment meets an installation requirement, an operator tightly grips the pulling hammer and quickly slides from the left end to the right end of the drawing to strike the nut 3, so that the pull rod 1 is driven to move rightwards, so that the wedge-shaped section is quickly withdrawn from between the two bolt heads 4, and the screwing operation of one bolt pair is completed.
