Background
The existing straightening scheme of the front section of the transmission shaft is to position a welding fork central hole and a spline shaft central hole, and then straighten the jumping T of the shaft tube part to the process requirement range by using straightening equipment. Because the center hole is only a process reference of the spline shaft and the welding fork, and the spline matching error and the middle fork position error are added, even if the center hole is straightened to the process requirement range according to the technical scheme, the whole jump still does not meet the requirement after the whole transmission shaft is assembled.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a transmission shaft front section straightening mechanism with a clamp spring groove positioned.
The invention aims at being completed by the following technical scheme: the utility model provides a transmission shaft front section alignment mechanism of jump ring groove location, mainly include the plug assembly, spring A, spring B, the revolving axle, the earhole, the round hole, open mechanism, the connecting rod, jump ring groove, insert the plug assembly in the earhole, the revolving axle is inserted at the plug assembly middle part, be equipped with spring B suit outside the plug assembly between revolving axle top and the earhole, be equipped with a round hole on the platform of plug assembly below, pass the connecting rod in the round hole and pass through the connecting rod and install open mechanism, open mechanism realizes opening and embedding in the jump ring groove in the earhole through the spring A of suit outside the connecting rod, under spring A's effect, open mechanism supports tight jump ring groove, realize the rotatory alignment with jump ring groove as the benchmark.
The core rod assembly consists of three sections of cylinders, a platform is arranged on the upper portion of one section of cylinder at the bottom, and a round hole is formed in the center of the platform.
The beneficial effects of the invention are as follows: according to the invention, the welding fork and the middle fork earhole clamp spring groove are directly used as positioning references, and the design references are directly used as alignment references for alignment, so that the alignment effect is more real, and the transmission and accumulated errors of parts are avoided; the actual quality effect of the straightening process is improved, the jumping requirement of the transmission shaft after the whole assembly is guaranteed, and the whole quality of the transmission shaft is improved.

Detailed Description
The invention will be described in detail below with reference to the attached drawings:
examples: as shown in the drawing, the transmission shaft front section straightening mechanism with the clamp spring groove positioned mainly comprises a core rod assembly 9, a spring A10, a spring B11, a rotary shaft 12, an ear hole 14, a round hole 15, an opening mechanism 16, a connecting rod 17 and a clamp spring groove 18, wherein the core rod assembly 9 is inserted into the ear hole 14, the rotary shaft 12 is inserted into the middle part of the core rod assembly 9, the spring B11 is sleeved outside the core rod assembly 9 between the upper part of the rotary shaft 12 and the ear hole 14, the core rod assembly 9 is composed of three sections of cylinders, a platform is arranged at the upper part of one section of cylinder at the bottom, and the round hole 15 is arranged at the center of the platform. The circular hole 15 passes through the connecting rod 17 and is provided with the opening mechanism 16 through the connecting rod 17, the opening mechanism 16 is opened through the spring A10 sleeved outside the connecting rod 17 and is embedded into the snap spring groove 18 in the earhole 14, and the positioning by the snap spring groove 18 is realized; under the action of the spring A10, the opening mechanism 16 abuts against the clamp spring groove 18, so that the rotation straightening taking the clamp spring groove 18 as a reference is realized.
The working process of the invention comprises the following steps: the mandrel assembly 9 is inserted into the ear hole 14, the pivot shaft 12 and the spring B11 until the opening mechanism 16 enters the snap spring groove 18. Due to the action of the spring A10, the opening mechanism 16 abuts against the clamp spring groove 18, and the effect of rotating and straightening by taking the clamp spring groove 18 as a reference is achieved. After the straightening is completed, the rotary shaft 12 is taken out, and then the core rod assembly 9 is pushed out forwards continuously, so that the disassembly is completed.
It should be understood that equivalents and modifications to the technical scheme and the inventive concept of the present invention should fall within the scope of the claims appended hereto.
