A pen tube positioning device

Abstract

The invention discloses a pen barrel positioning device. The pen barrel positioning device comprises a positioning mechanism; the positioning mechanism sequentially comprises connection rods, upper pressing caps, lower pressing caps, connection sleeves, positioning rods and positioning sleeves from top to bottom; connection holes are formed in the connection sleeves; connection grooves are formed in the outer side walls of the connection sleeves; the lower portions of the connection rods are arranged in the connection holes; telescopic grooves are formed in the lower portions of the connection rods; clamping blocks are embedded in the telescopic grooves and the connection grooves jointly; the upper portions of the positioning rods are fixed in the connection holes; the upper pressing caps are fixed to the middle portions of the connection rods; the connection rods are sleeved with the lower pressing caps; springs are arranged between the upper pressing caps and the lower pressing caps; convex blocks are arranged at the bottoms of the positioning rods; the positioning sleeves are fixed to the lower portions of the positioning rods; and positioning grooves are formed in the positioning sleeves and in the bottoms of the positioning rods. The pen barrel positioning device is safe, reliable, convenient, fast and efficient.

Description

technical field [0001] The invention relates to the technical field of non-standard automation, in particular to a pen tube positioning device. Background technique [0002] Pen stationery usually includes a pen cover. The pen cover is generally composed of a pen clip, a pen tube and a pen cover sealing ring placed in the pen tube. When the pen cover is placed on the pen body, the pen The tube not only brings beauty to the pen stationery, but also facilitates the protection of the pen stationery. Before assembling the pen holder with the pen tube, the pen tube needs to be positioned so that the groove on the top of the pen tube is at the designated position; currently, The positioning of the pen tube in the pen holder is usually done manually, and the efficiency is low. Therefore, it is necessary to develop an automatic positioning device for the pen tube. Contents of the invention [0003] Aiming at the deficiencies in the above technologies, the present invention provid...
