Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
The utility model provides a spline shaft tip processing is with pressing from both sides tight frock, includes the frock body, the frock body includes casing 1, clamping sleeve 2, bloated cover 3 and uide bushing 4, clamping sleeve 2 establishes inside casing 1, uide bushing 4 and bloated cover 3 establish respectively in the inside left side and the right side of clamping sleeve 2, the left side of uide bushing 4 still is equipped with establishes at the inside pull rod hydro-cylinder 5 of clamping sleeve.
The right end of the shell 1 is provided with a baffle 6, the baffle 6 is provided with a groove 7, and a butterfly bolt 8 for connecting the baffle 6 and the shell 1 is arranged in the groove 7.
The pull rod of the pull rod oil cylinder 5 is in threaded connection with the clamping sleeve 2, and the guide sleeve 4 is in threaded connection with the clamping sleeve 2.
U-shaped grooves 9 are uniformly formed in the circumference of the expansion sleeve 3, the U-shaped grooves 9 are arranged on the expansion sleeve 3 in the opposite direction along the axis, and twelve U-shaped grooves 9 are formed.
Clamping grooves 10 are uniformly formed in the clamping sleeve 2 on the outer side of the expansion sleeve 3, and the number of the clamping grooves 10 is six.
The clamping sleeve 2 and the shell 1 outside the expansion sleeve 3 are of mutually matched conical structures, and the conicity of the conical structures is 20 degrees.
When the spline shaft end part machining device is used, the shell 1 is fixed on a flange plate of a lathe, the butterfly bolt 8 is unscrewed, the baffle 6 is taken down, one end of the spline shaft is sequentially arranged in the expansion sleeve 3 and the guide sleeve 4 (the arrangement depth can be adjusted along with the machining position), after the baffle 6 and the shell 1 are fixed through the butterfly bolt 8, the clamping sleeve 2 is pulled by the pull rod oil cylinder 5 to move leftwards, so that the clamping groove 10 in the clamping sleeve 2 is tightened, the spline shaft is clamped by the expansion sleeve 3, and the end part of the spline shaft can be machined. Adopt the tight cover 2 of clamp and expand the cover 3 and tighten up simultaneously, and the tight position of clamp and the position of processing are the shortest, have guaranteed that the integral key shaft adds the vibration deformation not in man-hour, guarantee the machining precision, reduce the disability rate, practice thrift the cost, uide bushing 4 can realize quick central location, practices thrift the adjustment time after the clamping at every turn, improves work efficiency.
