Key bit groove milling device

Abstract

The invention discloses a key bit groove milling device. The key bit groove milling device comprises a feeding rack, a milling cutter, a pushing device and a discharging outlet. A feeding groove is formed in the feeding rack, and an opening is formed in the feeding groove and located at the tail position of a key bit. The pushing device comprises a pushing plate and a groove milling cylinder. A cylinder shell is arranged above a cylinder support arm of the groove milling cylinder. The pushing plate is provided with round through holes, is further fixed above the cylinder shell by means of locking of bolts and the round through holes and can move front and back along with the cylinder support arm. When being subjected to batch groove milling, the key bit can be stably located inside the feeding rack, and the disengaging problem of the key bit can be avoided; and moreover, the pushing plate can be firmly fixed above the cylinder shell on the cylinder support arm located in the groove milling cylinder, the problem that the pushing plate is gradually disengaged from a pneumatic assembly to cause location deviation cannot happen, and thus effective work of the key bit groove milling device cannot be influenced.

Description

technical field [0001] The invention relates to the field of key processing equipment, in particular to a key head groove milling device. Background technique [0002] A key with a key shell is generally composed of a key head and a key shell. To make such a key, it is first necessary to mill the teeth and slots of the key head, and finally assemble the key head into the key shell. When milling the key head, in the existing key head milling machine, the feed frame used to prevent the key head is generally composed of a front bar, a rear bar, a left bar and a right bar. Wherein the back bar, the left bar and the right bar are close together and are used to limit the position of the key head, and there is a gap between the front bar and the left bar and the right bar for putting the key head into it. However, when the milling machine mills the key head, it will be accompanied by vibration, and as the milling progresses, the key head is very easy to fall from the gap, which wi...

Problems solved by technology

[0003] In order to solve the above problems, the object of the present invention is to provide a key head groove milling device. When the key heads are batch milled, the key heads can be stably placed in the feed rack, and the problem of key head falling will not occur. And the push plate can be firmly fixed on the cylinder shell on the cylinder support arm in the milling cylinder, and there will be no problem that the push plate is gradually detached from the pneumatic component and the position will be shifted, so it will not affect the key head milling device. work effectively
