Device used for accurate rear location and rapid unloading for numerically-controlled lathe

Abstract

The invention discloses a device used for accurate rear location and rapid unloading for a numerically-controlled lathe. The device comprises a location assembly, an ejection rod (5) and an unloadingassembly, wherein the location assembly and the unloading assembly are installed on the front part and the rear part of the ejection rod (5) separately. The device is characterized in that a locationdevice comprises an outer sleeve (3) and a clamping block (2), the clamping block (2) is installed on the front part of the outer sleeve (3) in a sleeving manner, a plurality of bolts B (4) are installed on the rear part of the outer circumferential surface of the outer sleeve (3), and the ejection rod (5) is installed in a through hole of the clamping block (2) and penetrates through the cavity of the outer sleeve (3); and an unloading device comprises a sleeve pipe (6), a spring (7) and a pusher (8), the rear end of the ejection rod (5) is installed on the front half part in the sleeve pipe(6), the pusher (8) is installed on the rear half part in the sleeve pipe (6), and the spring (7) is installed outside the pusher (8) in a sleeving manner. The device disclosed by the invention is accurate, efficient and stable, and suitable for the popularization and use of accurate rear location and rapid unloading for the numerically-controlled lathe.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing auxiliary devices, and in particular relates to a device for precise rear positioning and fast unloading of a numerically controlled lathe. Background technique [0002] As an indispensable connector in production, pins play a pivotal role in the connection of mechanical parts. The pin is a very small part (such as φ3×6), and the machining process is difficult. During existing processing (such as Figure 7 ), there are the following problems: First, there are a large number of pins, which will cause the clamp block to loosen slightly during the frequent clamping process of the circlip, resulting in a pin length of 6 0 -0.1 out of tolerance; Unable to hold, resulting in low processing efficiency; third, complex structure and poor operability. Existing devices have been unable to solve the above problems. Contents of the invention [0003] The purpose of the present invention is t...
