Problems solved by technology

[0003] Image 6 , Figure 7 The part shown is an existing 7C yoke sleeve with a width of mm, 6mm deep, keyway 51 with a symmetry of 0.03mm based on the spline index circle, the traditional processing method is to use the spline mandrel to locate, and use the connection structure composed of a pneumatic cylinder or a hydraulic cylinder to press the inner socket. For milling on the milling machine, due to the wear of the milling cutter, frequent replacement of the cutter and long processing time, etc., the processing efficiency is too low, the production progress is delayed, and the production cost is increased.

Abstract

The invention discloses a broaching fixture for a key groove of a connection fork sleeve, which comprises a fixture body, wherein a rabbet adapted to a machine tool is formed in the left end of the fixture body; a broach backing plate is arranged on the fixture body; a broach is arranged on the broach backing plate; the fixture body is connected with a locating disc which is used for locating the excircle and the end face of a workpiece; the broach penetrates through the locating disc; and two workpiece pressing devices for pressing the workpiece is arranged on the fixture body. Each of the two workpiece pressing devices comprises an oil cylinder, wherein connection plates are articulated with the tops of oil cylinder connection rods; supports are articulated with the middle parts of the connection plates; a pressing rod is articulated with the other end of each connection plate; and pressing heads are connected with the bottom ends of the pressing rods. When the broaching fixture is in operation, the pressing heads press the workpiece downwards; and the two workpiece pressing devices are arranged on two sides of the locating disc and used for pressing two ends of the workpiece. According to the broaching fixture for the key groove of the connection fork sleeve, on the premise that the processing precision of the workpiece is ensured, the labor intensity of a worker is reduced, and the production efficiency is greatly improved; in addition, the replacing frequency of the broach is reduced, and the cost of production and manufacturing is lowered.

Description

technical field [0001] The invention relates to a fixture for a machine tool. Background technique [0002] With the rapid development of my country's industrial manufacturing and the advancement of mechanical technology, the competition in the field of mechanical processing has become increasingly fierce. The mechanical processing industry has entered the era of meager profits. This situation forces the mechanical processing industry to continuously innovate and improve, abandon the previous production methods with high energy consumption, high consumables, high labor intensity and low efficiency, and actively look for energy saving and consumption reduction. A new approach to manpower and material resources. [0003] Figure 6 , Figure 7 The part shown is an existing 7C yoke sleeve with a width of mm, 6mm deep, keyway 51 with a symmetry of 0.03mm based on the spline index circle, the traditional processing method is to use the spline mandrel to locate, and use the con...
