Machining clamp for workpiece with taper hole on numerical control machine tool

Abstract

The invention discloses a machining clamp for a workpiece with a taper hole on a numerical control machine tool. The machining clamp comprises a base, the upper side of a first end plate is fixedly connected with a top plate, the bottom side of the top plate is fixedly connected with a worm, the first end plate is fixedly connected with a connecting rod, the right end of the connecting rod is fixedly connected with a mounting plate, a third rotating shaft is rotatably connected to the connecting rod in a penetrating manner, the left end of the third rotating shaft is fixedly connected with a worm wheel, and the right end of the third rotating shaft is fixedly connected with a first bevel gear; and lead screws are symmetrically and rotationally connected into the mounting plate, second bevel gears are fixedly connected to the ends, away from the inner wall of the mounting plate, of the lead screws, the first bevel gear is connected with the second bevel gears in a meshed manner, movingrods are symmetrically and slidably inserted into the right side of the mounting plate in a penetrating manner, and clamping plates are fixedly connected to the moving rods. According to the machiningclamp, the workpiece is placed between the two clamping plates, then the second rotating shaft is connected with the worm, and a double-shaft motor is started, so that the clamping plates move up anddown to clamp the workpiece.

Description

technical field [0001] The invention relates to the technical field of machine tool fixtures, in particular to a machining fixture for a workpiece with a tapered hole on a numerically controlled machine tool. Background technique [0002] In the process of mechanical manufacturing, it is used to fix the processing object so that it occupies the correct position to accept the construction or inspection device, also known as fixture. In a broad sense, any process in the process is used to quickly, conveniently and safely The device that installs the workpiece can be called a fixture, such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing workpieces on machine tools, in order to make the surface of the workpiece To meet the technical requirements such as size, geometric shape and mutual position accuracy with other surfaces stipulated in t...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem in the prior art that "because the outside is mostly fixed by bolts, the inside of the taper hole of the taper hole workpiece cannot be limited and fixed, resulting in relatively low stability when fixing the taper hole workpiece during processing." At the same time, because most of the bolts are fixedly connected to the device through the fixing plate, when the size of the tapered workpiece changes, the staff needs to replace the device before processing, which reduces the work efficiency.
