Abstract
The positioning pin of anti-rotation limit function when being tightened the utility model discloses a kind of band.Positioning pin top is provided with bolted connection, bolted connection top peripheral face is equipped with flange, there are side plane portion in flange two sides, the side plane portion is the notch that the section formed after flange two sides are cut is perpendicular, the perpendicular in side plane portion limits on caliper confined planes, prevents positioning pin from rotating when twisting bolt.Without preventing positioning pin from rotating with spanner when the positioning pin assembly of the utility model, assembly efficiency is improved.
Description
Technical field
The utility model relates to anti-rotation limit functions when technical field of automobile parts more particularly to a kind of band are tightened to determine
Position pin.
Background technique
It is higher and higher now with industrial automation level, force requirement of the company to production efficiency higher and higher,
The ratio that float type brake caliper assembly uses in motor vehicle braking system is very high, therefore the utility model is mainly for floating type system
Dynamic pincers assembly design.It needs to be prevented with other assembly tools (such as spanner) in the positioning pin assembling process of float type brake caliper assembly
Only positioning pin rotates, so that assembly efficiency reduces, so designing a kind of positioning for being not necessarily to other assembly tools in assembling process
Pin has a vast market foreground.
Utility model content
In order to solve the problems in background technique, the utility model provides a kind of determining for anti-rotation limit function when band is tightened
Position pin, can be reduced assembly tool, to effectively improve assembly efficiency.
The technical solution of the utility model is as follows:
The positioning pin top of the utility model is provided with bolted connection, and bolted connection top peripheral face is equipped with flange,
There are parallel side plane portion in flange two sides, and the side plane portion is the plumb cut formed after flange two sides are cut.
The ear bottom of caliper two sides is equipped with confined planes, the plumb cut and caliper confined planes in one of side plane portion
It fits, for preventing positioning pin from rotating.
The positioning pin is mounted between caliper and bracket.
The positioning pin lower part forms hex surface after being cut.
The bolted connection end face center is provided with threaded hole, and bolt passes through the bolted connection phase of caliper and positioning pin
Even.
The beneficial effects of the utility model are:
1) the positioning pin mounting means of the utility model is similar to common positioning pin and replacement restructuring is convenient, cost variation
Less.
2) the utility model can make positioning pin that can hold out against limit with caliper confined planes in using bolt assembly rundown process,
It need to prevent positioning pin from rotating assembly tool with spanner to reduce, production efficiency is provided.
Detailed description of the invention
Fig. 1 is the front view of the utility model positioning pin；
Fig. 2 is the perspective view of the utility model positioning pin；
Fig. 3 is the installation top view of the utility model positioning pin；
Fig. 4 is the installation partial schematic diagram of the utility model positioning pin.
In figure: 1. positioning pins, 2. calipers, 3. brackets, 11. bolted connections, 12. side plane portions.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
As shown in Figure 1,1 top of positioning pin is provided with bolted connection 11,11 top peripheral face of bolted connection is equipped with convex
There are parallel side plane portion 12 in edge, flange two sides, and side plane portion 12 is the plumb cut formed after flange two sides are cut,
Flange two sides make flange outer profile in kidney-shaped after being cut.
As shown in Fig. 2, 1 lower part of positioning pin forms hex surface after being cut, for limiting positioning pin rotation.Bolted connection
11 end face centers are provided with threaded hole, and bolt passes through caliper 2 and is connected with the bolted connection 11 of positioning pin 1.
As shown in Figure 3 and Figure 4, positioning pin 1 is mounted between caliper 2 and bracket 3, and the ear bottom of 2 two sides of caliper is all provided with
There are confined planes, the plumb cut in one of side plane portion 12 of positioning pin 1 limits on 2 confined planes of caliper, passes through caliper 2
Confined planes and side plane portion 12 form resistance and positioning pin 1 are limited when tightening or unscrewing.Wherein, caliper, bracket belong to
In the original component of brake caliper assy.
The specific implementation course of work of the utility model is as follows:
When tightening bolt in brake caliper assy assembling process, positioning pin 1 is taken advantage of a situation rotation, the side plane portion 12 of positioning pin 1 with
When the limit face contact of caliper 2, due to the position-limiting action in side plane portion 12 and confined planes, positioning pin 1 can not continue to rotate, in this way
The purpose that bolt is tightened just can be realized without other assembly tool fixed locating studs 1, improve assembly efficiency.
Examples detailed above is the further explanation to the utility model, is not the specific restriction to the utility model, any right
Structure after the utility model simple transformation belongs to the protection scope of the utility model.
