Embodiment Construction

[0023] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0024] such as 1 and Figure 5 A fixture for processing three-way workpieces in small batches is shown, which includes a fixture body 1 and a holder 2. The fixture body 1 includes a first body 1.1 and a second body 1.2 coaxially arranged. The first body 1.1 and the second body 1.2 are coaxially arranged. The inner hole of the main shaft of the lathe is close to the axial direction, the first body 1.1 and the second body 1.2 are in the shape of a cylinder, the diameter of the second body 1.2 is larger than the diameter of the first body 1.1, and the end of the second body 1.2 is recessed inward. There is a space for holding the holder 2, a groove 1.3 is provided in the center of the bottom surface of the space for holding the holder 2, and a screw 1...

Abstract

The invention discloses a clamp for machining a small batch of tee workpieces. The clamp comprises a clamp body and a retainer, wherein the clamp body comprises a first body and a second body which are coaxially arranged; the first body is axially adjoined to an inner hole of a lathe spindle; the first body and the second body are both of cylinder shapes; the diameter of the second body is greater than that of the first body; a space for accommodating the retainer is inwards sunken in the end part of the second body; a groove is formed in the center of the bottom surface of the space for accommodating the retainer; a screw for locking the retainer is arranged on the second body; the retainer is of a cuboid shape; a mounting region for accommodating the tee workpieces is inwards sunken in the side surface of the retainer; two groups of parallel locking countersink threaded holes are formed in the retainer; the locking countersink threaded holes are matched with the screw; and a convex block matched with the groove is arranged at the bottom of the retainer. The clamp disclosed by the invention realizes quick and precise locating for clamping of the tee workpieces.

Description

technical field [0001] The invention relates to the technical field of part processing, in particular to a fixture for processing three-way workpieces in small batches. Background technique [0002] Processing three-way workpieces has always been a difficult problem in turning. The commonly used method is to align individually on the four-jaw chuck and process each end face. This method leads to the accuracy or shape tolerance of the processed workpiece depends on the operator of the equipment, and the processing quality cannot be guaranteed. In the case of large-scale production of three-way workpieces, the turning equipment will be modified to equip the equipment with hydraulic or pneumatic indexing chucks, so that after one end is processed, the indexing chuck can be directly indexed, and the conversion needs to process three-way The end face of the workpiece, this mass production method can guarantee the shape and position tolerance of the three-way workpiece. But when...
