Description
Technical Field
The utility model belongs to the technical field of automobile punching part examines utensil technical field and specifically relates to an all-round detection frock of foldable U profile overturns is related to.
Background
In order to improve product quality, automobile punching part need carry out the quality management and control after rolling off the production line. For large-scale workpieces with complex shapes, such as side walls (see fig. 1), not only are open holes (or half open holes a) formed in the large-scale workpieces, but also complex structures, such as U-shaped surfaces, are arranged on the inner side surfaces of the open holes, and when quality detection is carried out, not only is the overall roundness of the open holes detected, but also the machining precision of the U-shaped surfaces of the stamping parts at the positions is detected along the cross sections (such as the positions b in fig. 1) of the U-shaped surfaces. The existing checking fixture cannot detect the latter, so that the traditional three-coordinate mode can be only utilized for detection, and time and labor are wasted.
Disclosure of Invention
In order to solve the detection problem of large-scale stamping workpiece cross section precision, the utility model provides a simple operation, detect accurate upset foldable U profile all-round detection frock specifically can take following technical scheme:
all-round detection frock of foldable U profile of upset, include
The bottom of the fixed seat is arranged on a workpiece to be detected;
the detection assembly consists of a first detection arm and a second detection arm, the first detection arm is arranged above the workpiece to be detected, one end of the first detection arm is connected with the top of the fixed seat, and the other end of the first detection arm is hinged with the second detection arm; the second detection arm is positioned on one side of the opening of the workpiece to be detected and is positioned through a limiting pin positioned on the first detection arm;
when the second detection arm is in contact with the limiting pin, the first detection arm and the second detection arm are located at detection positions.
The first detection arm consists of a fixed section and a turning section, the first end of the fixed section is connected with the top of the fixed seat, and the second end of the fixed section extends towards the hole opening direction of the workpiece to be detected; the overturning section is positioned above the workpiece to be detected, one end of the overturning section is connected with the second end of the fixing section through more than two pins, and the other end of the overturning section is hinged with the second detection arm.
The overturning section and the second detection arm are positioned through the first positioning pin or the second positioning pin.
The utility model provides an all-round detection frock of foldable U profile of upset, the structure is small and exquisite, and convenient to use is convenient for install and deposit, can detect the size precision of large-scale stamping workpiece cross section convenient and fast ground, has alleviateed measurement personnel's work load greatly, has effectively promoted the control efficiency of the whole quality of part.

Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 2 and 3, the turnover foldable U-shaped surface all-directional detection tool of the present invention includes a fixing base 1 and a detection assembly, wherein the bottom of the fixing base 1 is mounted on a workpiece M to be detected through bolts, and is usually located outside the workpiece M to be detected (i.e. on the opposite side of the U-shaped surface to be detected); the detection assembly comprises a first detection arm and a second detection arm, wherein the first detection arm is positioned above the workpiece M to be detected and consists of a fixed section 201 and an overturning section 202, the first end of the fixed section 201 is connected with the top of the fixed seat 1, and the second end of the fixed section 201 extends towards the hole opening direction of the workpiece M to be detected; one end of the turning section 202 is connected with the second end of the fixed section 201 through more than two pins L, and the other end of the turning section is hinged with the second detection arm 203 through a hinge shaft 301; the second detecting arm 203 is located at the side of the opening of the workpiece M to be detected, and is positioned by the limit pin 302 located on the first detecting arm turning section 202.
When the workpiece M to be detected is detected, the turning section 202 is located above the workpiece M to be detected, the second detection arm 203 rotates around the hinge shaft 301 under the action of gravity until contacting with the limit pin 302, at the moment, the inner side surfaces of the turning section 202 and the second detection arm 203 are in copying with the surface to be detected of the workpiece M to be detected, and are arranged at an interval of 3mm with the surface to be detected of the workpiece M to be detected according to related detection standards. In order to fix the relative positions of the turning section 202 and the second detection arm 203, a first positioning pin 401 is usually inserted between the two for positioning; and then, measuring the actual gaps between the fixed overturning section 202 and the workpiece M to be detected and the second detection arm 203 through a gap ruler, and comparing the actual gaps with design data to obtain the profile accuracy of the detected part. After finishing detecting, take out first locating pin 401, the second detection arm 203 that upwards overturns makes it and upset section 202 syntropy setting to through the fixed position between them of second locating pin 402, then, remove fixing base 1 and wait to detect being connected of work piece M, will the utility model discloses take off from waiting to detect work piece M. Further, in order to reduce the storage space and meet the requirement of batch storage, the turning section 202 is taken down from the fixed section 201 and then turned over for 90 degrees to be connected to the fixed section 201, so that the second detection arm 203 and the turning section 202 are both vertically arranged.
It should be noted that in the description of the present invention, terms of orientation or positional relationship such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
