Problems solved by technology

When milling broach splines, theoretically, the three-jaw chuck and the rear center are used to position and clamp the broach. The tip cannot be mounted on the tip, and because the broach is mostly a slender piece, the rigidity is poor, if the tip is used to withstand the milling spline at both ends, it is easy to produce a "broach phenomenon"
The traditional fixture is difficult to guarantee the accuracy of the spline of the milling broach, and the adjustment is troublesome and takes a long time, which greatly increases the auxiliary production time

Embodiment Construction

[0015] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0016] During specific implementation, combined with figure 1 , a spline clamp for milling and broaching cutters, comprising a base 1 on which a support 3 and a fixing block 11 are installed. The support 3 can be fixed on the base by screws, and the screws can be hexagon socket cap screws 4 . A double-ended screw 5 passes through the support 3 and one end is connected with the slider 6, and the other end is connected with the left and right adjustment nuts 2. Turning the left and right adjustment nuts 2 can control the left and right movement of the slider 6, thereby realizing the left and right position adjustment of the fixture to the workpiece. The slider 6 can be fixed on the base 1 by a hex head bolt 7 . A vertical adjustment nut 9 is ins...

Abstract

The invention discloses a broach spline milling clamp. The broach spline milling clamp comprises a base. A support and a fixing block are mounted on the base. A double-headed screw penetrates the support, one end of the double-headed screw is connected with a sliding block, and the other end of the double-headed screw is connected with a left-right adjusting nut. A vertical adjusting nut is mounted on the upper portion of the sliding block. A V-shaped supporting frame is mounted above the vertical adjusting nut. A supporting rod and a stud are mounted on the fixing block. One end of a pressing plate is connected with the supporting rod, and the other end of the pressing plate penetrates the stud and is fixed through a locking nut. A spring is mounted on the stud. A nut is mounted on the supporting rod. The broach spline milling clamp is simple in structure, convenient to manufacture, convenient to maintain and use, capable of achieving quick and precise positioning through up-down left-right adjustment and capable of achieving machining of small-batch varieties of products, the machining precision of a broach is guaranteed, the production auxiliary time is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of clamps, in particular to a spline clamp for milling and broaching cutters. Background technique [0002] The broach is the main tool for processing internal spline workpieces. In actual production, the broach belongs to the production type of multiple varieties and small batches. When milling broach splines on a milling machine, traditional fixtures are generally used for processing, and each piece must be corrected for axis, tool setting, loading and unloading. When milling broach splines, in theory, the three-jaw chuck and the rear center are used to position and clamp the broach, but in actual processing, because the broach is long and the milling machine table we use for processing is short, it is fundamental The top cannot be supported, and since the broaches are mostly slender parts with poor rigidity, if the tops are used to withstand the milling spline at both ends, it is easy to produce a "broac...
