Description

Bracket detection device

Technical Field

The invention relates to the technical field of part detection, in particular to a bracket detection device.

Background

With the continuous promotion of the automobile industrialization technology, the automobile market is more mature, and the requirements on the size precision and the quality control of automobile products are higher and higher. The automobile inspection device is characterized in that free-form surfaces on automobile parts are formed in a copying mode, and surface differences and gaps are reserved among the free-form surfaces, so that the size of a product is controlled, and the production efficiency and the control quality are improved. The detection purpose of the detection tool is different, and the detection tool generally comprises two types, one type is a metering type detection tool and is mainly used for measuring parameters such as the size, the position and the like of a product; the other type is a functional checking fixture which is mainly used for measuring the shape parameters of products.

For the detection of automobile bracket parts, the upper part surface position and the hole position of the parts are detected through a metering type detection tool, and the opening size and the coaxiality of the parts can also be detected through detection tools of some handheld blocks. The checking tools can detect the size deviation of the face hole of the product so as to guide the adjustment of the clamp and ensure that qualified parts are produced. However, the key to the assembly of the bracket type part on the vehicle body is not the position degree of the product on the vehicle body, but the relative position degree of the product overlapped with other parts. Most bracket parts are connected with triangular arm parts on a vehicle body through U-shaped clamp plates through bolts. In other words, the triangular arm parts are clamped in the U-shaped clamping plates, and when the positions of a plurality of joints of the triangular arm parts are different in space, the position relation of a plurality of U-shaped clamping plates of the bracket parts needs to be detected so as to meet the assembly condition. The assembly environment of the product on the vehicle body is complex, and the qualified size of a single face hole cannot guarantee the qualified assembly of the product on the vehicle body. To the detection of this aspect of relative position degree, traditional utensil and the detection frock of examining can not satisfy its demand.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 2, a bracket detecting device disclosed in an embodiment of the present invention includes a handheld bracket 1, a first fixture block 2, a second fixture block 3, and two fastening bolts 4; wherein first fixture block 2 is cylindrical, and the outer periphery of first fixture block 2 is articulated with the one end of handheld bracket 1 to first mounting hole has been seted up at first fixture block 2, first mounting hole and first fixture block 2 coaxial line. Similarly, the second fixture block 3 is also cylindrical, the outer circumferential surface of the second fixture block 3 is hinged to the other end of the handheld bracket 1, and a second mounting hole is formed in the second fixture block 3 and is coaxial with the second fixture block 3. It is noted that, during use, the axes of the first and second mounting holes are disposed at an angle, for example, the axes of the first and second mounting holes are perpendicular. Certainly, the hinge joint of the present embodiment may also be replaced by a fixed joint, in the assembly position of the bracket and the vehicle body with high requirement on the size, the fixed joint may be adopted to accurately detect the spatial position relationship between the two U-shaped clamping plates on the bracket, and in the case of allowing a certain error in the size assembly precision, the hinge joint of the present embodiment is adopted to adaptively rotate the position of the clamping block on the handheld bracket 1, thereby adapting to the error range. And when first fixture block 2 and second fixture block 3 when the joint respectively between two U-shaped splint, the first mounting hole on first fixture block 2 will align with the screw hole on the U-shaped splint, and the second mounting hole on second fixture block 3 also needs to align with the screw hole on the corresponding U-shaped splint, when the hole can't align, need pass screw hole and first mounting hole, the second mounting hole on the U-shaped splint respectively with two fastening bolt 4, if fastening bolt 4 can cooperate with the nut to screw up and make the U-shaped splint clamp block, then also can regard the mounting dimension of bracket as qualified.
