TECHNICAL FIELD

[0001] The present application belongs to the technical field of tooling, and particularly relates to a marking and positioning tool for spring piece D-head bolts, and also relates to a processing method of the tool. BACKGROUND

[0002] The head of a spring piece bolt is a D-head, and a spring piece is welded on the head of the D-head. Before being shipped, the D-head of the spring piece D-head bolt needs to be marked with a mark by using a pneumatic marking device. The prior art is to mark the D-head of the spring piece bolt by manually holding the spring piece bolt for positioning. Since the spring piece bolt is manually held for positioning, vibration is generated during pneumatic marking, the D-head deviates due to the fact that the rod of the spring piece bolt cannot be fixed by manual holding, the position of the D-head of the spring piece bolt is deviated, and even the mark is made on the outside of the D-head of the spring piece bolt. The consistency of the mark of the spring piece bolt after marking is poor. SUMMARY

[0003] The present application aims to overcome the above-mentioned defects and provide a marking and positioning tool for spring piece D-head bolts and a processing method of the tool, in which the spring piece D-head bolt does not deviate during processing, the marking quality of the spring piece D-head bolt is improved, and the mark of the spring piece D-head bolt after marking has good consistency.

[0004] The present application aims to overcome the above-mentioned defects and provide a marking and positioning tool for spring piece D-head bolts and a processing method of the tool, in which the spring piece D-head bolt does not deviate during processing, the marking quality of the spring piece D-head bolt is improved, and the mark of the spring piece D-head bolt after marking has good consistency.

[0005] The marking and positioning tool for spring piece D-head bolts comprises a tool holder, a positioning groove, a handle and a positioning hole, and is characterized in that the tool holder is provided with the positioning groove on the upper surface, and the tool holder and the positioning groove are provided with the positioning hole at the center.

[0006] The positioning groove is a through groove.

[0007] The positioning hole is a through hole.

[0008] The tool holder is provided with an integrated handle on the side surface.

[0009] The processing method of the marking and positioning tool for spring piece D-head bolts comprises the following steps.

[0010] 1) installing the spring piece D-head bolt;

[0011] The rod of the spring piece D-head bolt is inserted into the positioning hole on the upper surface of the tool holder, the spring piece of the spring piece D-head bolt is inserted into the positioning groove, and the lower surface of the D-head of the spring piece bolt is attached to the upper surface of the tool holder.

[0012] 2) marking and processing;

[0013] Mark the handle to the side, mark the processing above the center position of the spring leaf bolt D type head.

[0014] Compared with the prior art, the present application has obvious beneficial effects; from the above technical solution, it can be known that the positioning groove is arranged on the tool holder, and the positioning hole is arranged at the center of the tool holder and the positioning groove. The rod part of the spring leaf bolt is inserted into the positioning hole, and the spring leaf of the spring leaf bolt is placed in the positioning groove. During the processing, the spring leaf of the spring leaf bolt is positioned by the positioning groove connected through the positioning hole, so that the spring leaf bolt is prevented from vibrating and deviating during the processing. The spring leaf bolt is prevented from deviating during the processing, the marking quality of the spring leaf bolt is improved, and the marked spring leaf bolt has good consistency.
