Description
Technical Field
The utility model relates to an automobile manufacturing technical field, especially a be used for detecting instrument of riding on horse bolt inner arc radius.
Background
The radius of the circular arc of a workpiece can be measured by an R gauge, however, the radius of the inner arc of a saddle bolt used for heavy trucks and the like usually reaches about 120mm, and the radius is beyond the measuring range of the R gauge, so that the radius cannot be directly measured by the R gauge. In the actual production process, the measurement personnel usually make paper circular arc card by oneself and measure, and it is very inaccurate to measure, causes to ride that the inner arc laminating effect is not good, easily not hard up in the bolt use, and because the paper card fragile, the preparation is wasted time and energy, and production efficiency is low.
SUMMERY OF THE UTILITY MODEL
To the problem in the background art, the utility model provides a be used for detecting instrument of riding on horse bolt inner arc radius to solve prior art, low to riding on horse bolt inner arc radial measuring efficiency, measure unsafe problem.
The utility model aims at realizing through the technical scheme, it is including:
the utility model provides a be used for detecting instrument of riding horse bolt inner arc radius, it is U type structure to ride horse bolt, it comprises first screw rod section, circular arc section and the second screw rod section that connects gradually, its characterized in that to ride horse bolt: the instrument is a rectangular platelike structure body, the both ends of instrument are provided with first circular arc limit and second circular arc limit respectively, wherein the radius size on first circular arc limit with the radial lower extreme size of arc equals in the circular arc section, the radius size on second circular arc limit with the radial last extreme size of arc equals in the circular arc section, the width of instrument is less than the inboard interval of first screw rod section and second screw rod section.
Further, the upper limit size is 121mm, and the lower limit size is 119 mm.
Furthermore, 2 marks with different shapes are respectively arranged near the first circular arc edge and the second circular arc edge.
Further, the tool is made of a steel plate with the thickness of 2 mm.
Further, knurling is arranged on the front surface and the rear surface of the middle part of the tool.
Due to the adoption of the technical scheme, the utility model discloses following advantage has: the sizes of the two arc edges of the tool are respectively equal to the upper limit size and the lower limit size of the inner arc radius of the saddle bolt, so that the inner arc radius of the saddle bolt only needs to be detected by the two arc edges, the saddle bolt can be judged to be qualified as long as the size of the inner arc radius of the saddle bolt is between the sizes of the two arc edges, and the specific operation method can be described in the embodiment. Therefore, the tool disclosed by the invention is used for detecting the radius size of the inner arc of the riding bolt, and is high in efficiency and accurate in detection.

The drawings of the present invention are described below.
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic diagram illustrating an embodiment of detecting a first arc edge;
fig. 3 is a schematic diagram of detection by using a second arc edge in the embodiment.
In the figure: 1. a first arc edge; 2. a second arc edge; 3. a first screw section; 4. a circular arc section; 5. a second screw section.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
The tool for detecting the inner arc radius of the horseback riding bolt shown in the attached drawing 1 is a U-shaped structure body, the horseback riding bolt is composed of a first screw section 3, an arc section 4 and a second screw section 5 which are sequentially connected, the inner side arc surface of the arc section 4 is the inner arc surface of the horseback riding bolt, and in the embodiment, the qualified size of the inner arc radius process requirement of the horseback riding bolt is 120 +/-1 mm.
The tool is made of a steel plate with the thickness of 2mm and is a strip-shaped plate-shaped structural body, a first arc edge 1 and a second arc edge 2 are respectively arranged at two ends of the tool, wherein the radius of the first arc edge 1 is equal to the lower limit size 119mm of the inner arc radius of the arc section, and the radius of the second arc edge 2 is equal to the upper limit size 121mm of the inner arc radius of the arc section; a circular mark is arranged near the middle of the first arc edge 1, and a triangular mark is arranged near the middle of the second arc edge 2, so that an operator can conveniently identify two different arc edges; the width of the tool is smaller than the inner side distance between the first screw section 3 and the second screw section 5, so that the tool can be conveniently placed between the first screw section 3 and the second screw section 5 for measurement; knurling is arranged on the front surface and the rear surface of the middle part of the tool, so that the anti-skidding tool has an anti-skidding effect and is convenient to operate.
During detection, as shown in fig. 2, an operator firstly uses the first arc edge 1 of the tool to be attached to the inner arc surface of the arc section 4 as much as possible, and then uses the feeler gauge to check whether the feeler gauge can be inserted from any end part of the first arc edge 1 to the arc section 4 so as to detect whether a gap exists between two ends of the first arc edge 1 and the arc section 4;
then, as shown in fig. 3, an operator uses the second arc edge 2 of the tool to fit the inner arc surface of the arc section 4 as much as possible, and then checks with a feeler gauge to see whether the feeler gauge can be inserted from between the middle part of the second arc edge 1 and the arc section 4, so as to detect whether a gap exists between the middle part of the second arc edge 1 and the arc section 4;
the feeler can be selected according to the precision required by inspection, such as a feeler of 0.02mm, and the feeler is specified to pass through a gap and not to pass through the gap.
Judging whether the inner arc radius size of the saddle bolt is qualified or not according to the following modes:
1. and if a gap is reserved between any one end part of the first arc edge 1 and the arc section 4 and a gap is reserved between the middle part of the second arc edge 2 and the arc section 4, judging that the product is qualified.
2. If a gap exists between the middle part of the first arc edge 1 and the arc section 4 or a gap exists between any one end part of the second arc edge 2 and the arc section 4, the judgment is unqualified.
The schematic diagrams of the detection state that the inner arc radius dimension of the saddle bolt is qualified are shown in the attached figures 2 and 3.
