Flexible hollow ball easy-to-lock connection structure for carbon fiber frame

Technical Field

The utility model relates to a locating support technical field, in particular to an easy locking connection structure of flexible clean shot for carbon fiber frame.

Background

The machine manufacturing industry is the foundation of modern industry, and nowadays, with the increasing awareness of environmental protection and the increasing shortage of natural resources, the limited utilization of energy and resources and the reduction of pollution during production play an increasingly important role in production, with the long-term focus on improving productivity and processing quality. Facing the dual challenges of environment and energy, the transformation of the manufacturing industry also brings new development opportunities for the industry. With the revolutionary breakthrough and cross fusion of important fields such as information technology, new energy and new materials and the like and the forward direction, the manufacturing industry has gradually advanced to the lightweight and intelligent information era.

With the continuous development of the domestic automobile industry, the industry competition is increasingly severe, users have higher and higher requirements on the quality of automobiles, and in order to keep the product competitiveness of the whole automobile factory, the steps of automobile model updating and new automobile model launching are continuously accelerated, and meanwhile, each automobile factory also continuously adopts new technology and new technology, and the attention is turned to the development of the measurement technology. The development of the manufacturing technology can not leave the measuring technology at the same time, and the two technologies supplement each other and promote each other. The new measurement technology continuously reveals the defects of the new process, and further innovation and modification are further improved. The checking fixture and the clamp are used as basic components of a measuring technology, the functions of the checking fixture and the clamp in the production field are more and more obvious, the forms of the traditional checking fixture and the clamp special for a single vehicle model can not meet the requirements gradually, and a vehicle factory has higher requirements on the economy and the quick response capability of products of checking fixtures and clamp suppliers, so that the requirements on multifunction, flexibility and high efficiency are met, and the satisfaction degree of customers is directly determined at low cost. The general structural members of the checking fixture, the opening checking fixture, the measuring support, the clamp, the mounting tool and the gripping tool are usually fixed in position through a carbon fiber frame at present.

As shown in fig. 1, the carbon fiber frame used generally includes a carbon fiber tube 3, a hollow sphere 1 located at a connection node of the carbon fiber tube 3, and a connection ball 2 connecting the hollow sphere 1 and the carbon fiber tube 3, because the connection positions of the carbon fiber tube 3 and the hollow sphere 1 are various, the connection angle of the carbon fiber tube 3 relative to the connection ball 2 is also changed, so that a fixing pin 4 for fixing the end of the carbon fiber tube 3 and rotating the end is further provided in the connection ball 2. The connecting ball 2 has a complex structure, and comprises a waist groove 21 allowing the carbon fiber tube 3 to swing, a shaft hole 22 for fixing the hollow ball 1 and a transverse through hole 23 for penetrating the fixing pin 4, wherein the three holes are intersected at the ball center of the connecting ball 2. The assembly sequence of the structure is that the fixing pin 4 passes through the transverse through hole 23, the first screw passes through the fixing pin 4 and is primarily fixed with the carbon fiber tube 3, then the second screw passes through one fixing hole from the interior of the hollow ball 1 and is locked with the shaft hole 22. However, there are some limitations to this assembling process because one end of the first screw-locking screw is blocked by the hollow ball 1 at a specific position and cannot be locked from the rear end by the screwdriver at all, so the first screw can be fixed only before fixing the hollow ball 1. Once the first screw loosens, this will bring the frame structure to become flexible, influence the fixed precision of carbon fiber frame. The adjustment is not possible unless the hollow ball 1 is removed, and it is very inconvenient to remove a hollow ball 1 for a frame that has been assembled as a whole.

There is a need for an improved connection structure to solve the above problems.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 3 to 5, the utility model discloses a flexible clean ball easy locking connection structure for carbon fiber frame, clean ball 1 including the surface has a plurality of thru holes 11 and a plurality of fixed orifices 12, through passing second screw 6 fixed connection of fixed orifices 12 outside clean ball 1 connecting ball 2 and swing joint carbon fiber tube 3 on connecting ball 2, connecting ball 2 has the side direction through hole 23 that is used for pin joint fixed pin 4 ', the one end of carbon fiber tube 3 is fixed in on fixed pin 4' through first screw 5 along the direction of the axis of perpendicular to fixed pin 4 ', fixed pin 4' has and runs through its axial screw hole (not mark), the both sides of screw hole respectively are fixed with a head and are conical tip screw 7, the head of tip screw 7 supports the nut inboard of first screw 5. In this structure, the first screw 5 and the second screw 6 connect the carbon fiber tube 3, the connecting ball 2 and the hollow ball 1 in turn according to a conventional fixing mode, and at this time, the first screw 5 and the fixing pin 4' are not completely locked, but the first screw 5 is tightly pressed from both sides by two pointed screws 7. The tightness of the pointed screw 7 cannot be blocked by the hollow ball 7, so that even if the first screw 5 becomes loose, the pointed screw 7 can also conveniently compensate the gap between the first screw 5 and the locking fixing pin 4' and the carbon fiber tube 3, and the trouble of dismantling the hollow ball 1 and even the whole frame is avoided.

As shown in fig. 3, the pointed screw 7 is a hexagon socket screw. The distance that the pointed screw 7 extends into the connecting ball 2 depends on the actual position of the first screw 5, which is typically a socket head cap screw in order to prevent the nut from getting stuck.

As shown in fig. 3 to 5, the fixing holes 12 on the hollow sphere 1 are uniformly distributed, and the central angle between all the fixing holes 12 and the nearest fixing holes 12 is 45 °. Therefore, the hollow ball 1 can be connected with the carbon fiber pipes 3 from the upper, the lower, the left, the right, the front and the back, and the carbon fiber frame can be extended in a plurality of directions.

As shown in fig. 3 to 5, each through hole 11 is located between adjacent four fixing holes 12, and the ball between the through hole 11 and the adjacent fixing hole 12All the heart angles are

The through holes 11 can reduce the weight of the hollow ball 1 and also serve as avoiding positions for screwing, so that each fixing hole 12 penetrates through the center of the ball

The direction of contained angle can both find a plurality of wrong screw positions, avoids the interference between the frame construction to influence the installation.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
