Abstract

The invention discloses a five-surface interference-free machining clamp, and belongs to the field of mechanical equipment manufacturing. The clamp comprises a positioning bottom plate, and is characterized in that: two positioning modules are connected onto the positioning bottom plate in a sliding manner, each positioning module comprises a base, an external thread sleeve and an internal screw rod, a first bevel gear shaft is inserted into the internal screw rod, an annular groove is formed in the external thread sleeve, the diameter of the annular groove is larger than that of the threaded convex shoulder section of the internal screw rod, the height of the annular groove is larger than that of the threaded convex shoulder section of the internal screw rod, a supporting sleeve is connected to the base, a second bevel gear shaft is installed in the supporting sleeve, and the first bevel gear shaft and the second bevel gear shaft are in meshing transmission through a gear. According to the clamp, tensioning and loosening of parts can be easily achieved, the influence of the thickness of a blank on manufacturing of the auxiliary holes is effectively shielded, the auxiliary holes are single-face blind holes, standard manufacturing of the auxiliary holes is achieved, stepless adjustment of the distance between modules can be flexibly achieved, and the clamp is suitable for unified clamping of parts of different sizes.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment manufacturing, in particular to a five-sided non-interference processing clamp. Background technique [0002] The milling and clamping of small and medium-sized parts usually adopts the positioning method of "two holes on one side", and the machine is positioned by pressing the pressure plate for clamping. This method has the problems of long preparation time and interference processing by pressing the pressure plate. In order to solve this problem, two zero-point positioning systems are usually installed on the backing plate to realize a standardized "two holes on one side" clamping scheme. However, due to the large volume of the zero-point positioning system itself, the minimum distance between the two holes is large and cannot be applied to some parts. Small and medium-sized parts; and the zero-point positioning system has a fixed spacing. Even though multiple sets of serialized fi...
