A chuck assembly device for a refill assembly machine of an automatic pencil

Abstract

The invention relates to a head clamping combination device of a pencil lead combination machine of an automatic pencil. The head clamping combination device comprises a head clamping pressing base, ahead clamping pressing rod, a head clamping pressing warping plate, a warping plate pressing rod, a detection mechanism and a driving mechanism, wherein the head clamping pressing rod is arranged onthe head clamping pressing base and can move up and down, the head clamping pressing warping plate is arranged on the head clamping pressing base, and one end of the head clamping pressing warping plate abuts against one end of the head clamping pressing rod; and the warping plate pressing rod and the head clamping pressing rod are coaxially arranged and located at the upper end of the head clamping pressing warping plate, the warping plate pressing rod is connected with the detection mechanism, the driving mechanism drives the detection mechanism to do up-and-down lifting motion. The technical scheme of the device enables the clamping head and a clamp port to be quickly and accurately arranged in a clamping mode and the clamping connection condition of the clamping head and the clampingport to be detected, so that the pencil lead combination machine of the automatic pencil can efficiently and rapidly complete the combined assembly of pencil lead, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical automation, in particular to a chuck assembly device of a refill assembly machine of a mechanical pencil. Background technique [0002] Reference attached Figure 1-5 The refill 1 of the mechanical pencil is an important constituent mechanism of the mechanical pencil, including a lead storage tube 11, a spring 12, a spring seat cover 13 and a chuck 14 with a locking collar 15, and the lead storage tube 11 includes a body 111 , the first boss 112, the second boss 113, the bayonet 114, the spring seat cover 13 includes an inner end surface 131, an outer end surface 132, the chuck 14 includes an engaging end 142 and a claw piece 141, the refill 1 The combination is that the spring is sleeved on the second boss 113 so that one end of the spring 12 is against the upper end surface 1131 of the second boss 113, and the spring seat 13 is sleeved outside the spring 12 so that the other end of the spring 12 is in ...

[0002] Reference attached Figure 1-5 The refill 1 of the mechanical pencil is an important constituent mechanism of the mechanical pencil, including a lead storage tube 11, a spring 12, a spring seat cover 13 and a chuck 14 with a locking collar 15, and the lead storage tube 11 includes a body 111 , the first boss 112, the second boss 113, the bayonet 114, the spring seat cover 13 includes an inner end surface 131, an outer end surface 132, the chuck 14 includes an engaging end 142 and a claw piece 141, the refill 1 The combination is that the spring is sleeved on the second boss 113 so that one end of the spring 12 is against the upper end surface 1131 of the second boss 113, and the spring seat 13 is sleeved outside the spring 12 so that the other end of the spring 12 is in contact with the spring seat. The inner end surface 131 of the cover 13 is offset, and the engaging end 142 of the chuck 14 with the locking band 15 passes through the spring seat cover 13 and the spring and the bayonet 114 of the lead storage pipe 11 is snapped together, so that the locking band 15 and the lead storage tube 11 are engaged. The outer end surface 132 of the spring seat cover 13 offsets each other. At present, the combination of the mechanical pencil lead is manually performed, which is low in efficiency and high in cost.
