The inspection tool and the clamp are taken as basic components of the measuring technology, the functions of the inspection tool and the clamp are more and more obvious in the production place, the traditional single-vehicle-type special inspection tool and clamp form can not meet the requirement of on-line measurement gradually, and a vehicle factory has higher requirements on the economical efficiency and the quick response capability of products of inspection tools and clamp suppliers, so that the inspection tool and the clamp meet the requirements of multiple functions, flexibility and high efficiency, are not limited by the use situation, and directly determine the satisfaction degree of customers.
Chinese patent CN105352742a discloses a ball joint assembly for a carbon fiber support of an automobile gauge, wherein a joint is connected with a carbon fiber tube by inserting a cylindrical section into one end of the carbon fiber tube, and a plurality of annular grooves are provided in the middle of the outer wall of the cylindrical section. Although the function of the annular groove is not described in the patent, it can be inferred from the connection relation between the joint and the carbon fiber tube that the joint is connected by the connection glue, otherwise, the joint and the carbon fiber tube cannot be fixed. The annular groove is provided to assist in spreading the adhesive, which eventually flows into the very narrow gap to achieve an effective connection. However, this structure has many details when injecting the connection glue:
1. if the glue injection holes are formed in the carbon fiber tube, the strength of the carbon fiber tube is affected, and in order to avoid the effect, the connecting area can be increased only by increasing the height of the cylinder section, and a plurality of connecting structures are often arranged on one bracket, so that the total weight of the bracket is greatly increased when the connecting structures are accumulated, and the requirement of light weight is not met.
2. If the glue injection hole is arranged in the joint, the glue injection hole can only pass through the connecting hole, but the connecting hole is perforated, the pressure is not maintained, even if one end of the connecting hole is closed, the glue injection hole actually plays a role in connection, and only a small amount of connecting glue in a gap is formed, and the rest part is wasted in the pipeline in a large amount, so that the unnecessary weight is increased.
3. The gap structure between the annular grooves is unfavorable for the diffusion of the connection glue, because the gas in the gap does not flow out of the channel, the connection glue can be blocked from entering, and finally the effective connection area is small, and the tensile capacity of the connection structure is very unreliable.
It is therefore necessary to devise a new structure to solve the above problems.

Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example 1:
as shown in fig. 1 to 7, a carbon fiber bracket connecting assembly 1 of the present invention comprises a carbon fiber square tube 11 and two end caps 12 respectively connected to two ends of the carbon fiber square tube 11, the end caps 12 are provided with a bottom surface 121 and side walls 122 perpendicular to the bottom surface 121, the side walls 122 comprise four side surfaces 1221 respectively opposite to four inner walls of the carbon fiber square tube 11, the inner walls of the side surfaces 1221 and the carbon fiber square tube 11 opposite to the side surfaces 1221 are rough and have roughness of 50-150um, the end caps 12 are further provided with four glue injection holes 123, each glue injection hole 123 extends from the bottom surface 121 to the middle part of the side surface 1221, the gap between the side surface 1221 and the inner wall of the carbon fiber square tube 11 is 0.05-0.5mm, and the connecting glue 13 is filled in the gap.
Since drilling holes in the carbon fiber square tube 11 seriously affects the structural strength, the side wall 122 is bonded to the opposite surface of the carbon fiber square tube 11 by the connecting glue 13. The concrete method is that the side wall 122 is inserted into the port of the carbon fiber square tube 11, then the connecting glue 13 is injected from the glue injection hole 133, and the connecting glue 13 expands outwards from the middle part of the side face 1221 through the gap until the whole gap is filled. Since the inner wall of the carbon fiber square tube 11 where the side face 1221 and the side face 1221 face each other is rough, both surfaces are rugged from the microstructure, and an elastic force component in the interface direction can be generated to the convex portion when the joint compound 13 fills the concave portion. However, if the distance between the gaps is too large, the thickness of the adhesive 13 is too thick, which may reduce the tensile capacity of the cut surface; if the distance of the gap is too small, it is difficult to form an effective connection in the gap, which is disadvantageous to the diffusion of the connection paste 13, and also to the tensile ability. So that a sufficient tensile capacity can be achieved with a gap thickness of 0.05-0.5 mm. In practical application, the adhesive area of the adhesive 13 is about 6000 mm, and the generated tensile resistance is more than 6 tons.
As shown in fig. 3 to 5, the glue injection holes 123 are in a linear structure, the lower openings of the four glue injection holes 123 are all located below the bottom surface 121, the aperture of the glue injection holes 123 is 2-8mm, and the part of the glue injection holes 123 on the side surface 221 is a glue guiding groove 1231 with a semicircular cross section.
Since the side wall 122 is completely enclosed in the carbon fiber square tube 11 when the end cap 12 is assembled into the carbon fiber square tube 11, the outer wall of the carbon fiber square tube 11 cannot be perforated, so that drilling can be performed only from the lower surface of the bottom surface 121. The material of the end cap 12 does not need to be carbon fiber material, but can be metal or injection molding, and the drilling is convenient. Obviously, the glue injection hole 123 is used as a flow passage for the connecting glue 13, and the passing area is larger than the connecting gap, so that the generated resistance is smaller than the resistance flowing through the connecting gap, and a certain pressure can be maintained in the glue guide groove 1231, and the pressure is helpful for the outward diffusion of the connecting glue 13. Because the diffusion of the connecting glue 13 is from inside to outside, the connecting gap is easy to fill up, the hollow is not caused, the effective bonding area is large, and the tensile strength of the structure can be ensured.
As shown in fig. 4 to 6, the lower opening of the injection hole 123 has a circular cavity 1211, the diameter of the circular cavity 1211 is larger than that of the injection hole 123, and the axis of the circular cavity 1211 is parallel to the axis of the injection hole 123.
The injection may be performed by using a syringe, the circular cavity 1211 corresponds to the outer diameter of the syringe, the injection hole 123 corresponds to the outer diameter of the needle, and the injection hole 123 and the circular cavity 1211 also correspond to the relative position relationship because the syringe body is larger than the needle and the needle is offset to one side. After injection is completed, the inside of the circular cavity 1211 may be plugged with a plug to prevent the connection glue 13 from flowing out.
As shown in fig. 3, 4 and 7, the side wall 22 has an octagonal structure, a transition surface 1222 is disposed between adjacent side surfaces 1221, four corner regions of the bottom surface 121 are respectively provided with a fixing hole 1212, the fixing holes 1212 are used for penetrating threaded connectors (not shown), and inner ends of the threaded connectors are located in a space surrounded by the carbon fiber square tube 11 and the transition surface 1222.
Other components such as the base 2, another end cap 12, a clamp fixing plate, a gauge fixing plate, etc. are often connected to the outer side of the end cap 12, and a threaded connection is needed. The transition surface 1222 is arcuate in shape, but may be planar, and the provision of the transition surface 1222 provides for connection between the sides 1221 while avoiding the location of the threaded connection. The bonding paste 13 spreads to the transition surface 1222, and the bonding area is stabilized.
As shown in fig. 3, 5, 6 and 7, the end cap 12 has a top surface 124, and a through hole 1241 is provided in the middle of the top surface 124. The side wall 122 is hollow, the inner wall of the side wall 122 is provided with reinforcing ribs 1223 at the opposite positions of the glue injection holes 123, and the top surface 124 and the side wall 122 enclose a four-leaf groove structure.
The middle portion of the end cover 12 is recessed and the through holes 1241 are formed to reduce the material consumption of the end cover 12, so as to realize the light weight requirement. However, from a strength standpoint, the top surface 124 needs to have a connection to the side surface 1221 and the transition surface 1222, and the thickness loss of the injection molding hole 123 is compensated for by the ribs 1223, so that the material of the side surface 1221 is too thin to withstand the injection molding pressure.
Example 2:
as shown in fig. 8, a clamping device comprises a base 2, a carbon fiber bracket connecting assembly 1 fixed on the base 2, and a clamping assembly 3 fixed on the upper end of the carbon fiber bracket connecting assembly 1.
Example 3:
as shown in fig. 9, a positioning device comprises a base 2, a carbon fiber bracket connecting component 1 fixed on the base 2, and a positioning pin component 4 fixed on the upper end of the carbon fiber bracket connecting component 1.
Example 4:
as shown in fig. 10, a positioning and clamping device comprises a base 2, a carbon fiber bracket connecting component 1 fixed on the base 2, and a fixing plate 5 fixed on the upper end of the carbon fiber bracket connecting component 1, wherein the fixing plate 5 is provided with a clamping component 3 and a positioning pin component 4.
Therefore, according to different use requirements, the upper part of the carbon fiber bracket connecting component 1 can be matched with various functional components, including the clamping component 3 and/or the locating pin component 4, and the structures and the combinations of the base 2, the clamping component 3, the locating pin component 4 and the fixing plate 5 can be changed according to different use occasions, so that the stable positioning or clamping requirements on various tools are met.
What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
