Embodiment Construction
[0022] The present invention will be further described below in conjunction with specific examples.
[0023] Such as Figure 1~7 The outer dimension checker of a smoke collecting hood shown includes a fixed frame 6, on which an upper bracket 9, an intermediate bracket 11 and a lower bracket 8 are arranged at intervals from top to bottom, and the front of the lower bracket 8 A number of detection mechanisms 1 are arranged on the side. The detection surface of the detection mechanism 1 can be completely fitted with the plane where the front side plate of the qualified workpiece is located. Mechanism 3 7, the detection surface of detection mechanism 2 2 can completely fit the plane on the left side of the left side plate of the qualified workpiece, and the detection surface of the detection mechanism 3 7 can completely fit the plane on the right side of the right side plate of the qualified workpiece; The front side of the upper bracket 9 is provided with a detection mechanism 4...

The invention discloses an overall dimension testing tool of an exhaust fume collecting hood in the technical field of dimension detection. The testing tool comprises a fixed rack, the rack is provided with an upper support, a middle support and a lower support in sequence at intervals from top to bottom, the front side of the lower support is distributed with a plurality of first detection mechanisms, a detection surface of each first detection mechanism can be completely attached to a front side plate of a qualified workpiece, two ends of the upper side of the lower support are respectively provided with a second detection mechanism and a third detection mechanism, a detection surface of the second detection mechanism can be attached to a left side plate of the qualified workpiece, a detection surface of the third detection mechanism can be attached to a right side plate of the qualified workpiece, the front side of the upper support is provided with a fourth detection mechanism, a detection surface of the fourth detection mechanism can be attached to a front top board of the qualified workpiece, two sides of the upper support are respectively provided with a fifth detection mechanism and a sixth detection mechanism, a detection surface of the fifth detection mechanism can be attached to a left top board of the qualified workpiece, a detection surface of the sixth detection mechanism can be attached to a right top board of the qualified workpiece, and a to-be-detected workpiece is arranged on the middle support. According to the testing tool, the detection efficiency is high, and the detection precision is high.
Description
technical field [0001] The invention relates to a measuring tool for external dimensions, in particular to a device for detecting the external dimensions of a fume collecting hood. Background technique [0002] After the production of the fume collecting hood is completed, it is necessary to carry out strict inspection on the outer dimensions of the fume collecting hood to eliminate unqualified products. The left top plate, the right top plate and the front top plate together, the front top plate and the front side plate are spliced together by welding, the left top plate and the left side plate are spliced together by welding, and the right top plate and the right side plate are spliced together by welding Together, it is also necessary to detect the gap between the welds. When the flatness of the top plate and each side plate and the gap between the welds meet the specified requirements, the product is a qualified product and can be sent out for sale; otherwise, the ...
