Description

Technical Field

[0001] This utility model relates to the field of automated production equipment for functional pipe fittings, specifically to a pipe end lock assembly device. Background Technology

[0002] A functional pipe fitting is needed, comprising: a straight pipe with a locking head inserted at one end, and a rivet point at the end of the pipe with the locking head to secure it; an end cap at the other end of the pipe, with a ring of glue applied to its inner wall before assembly to secure it to the pipe end; and an intermediate section pre-installed on the straight pipe. All three components—the locking head, end cap, and intermediate section—are made of plastic. Currently, the installation of these three plastic components is done manually. Manual installation suffers from low efficiency, high labor costs, and inconsistent assembly quality. To achieve automated production, a pipe end locking head assembly device suitable for automated installation on assembly lines is urgently needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pipe end lock assembly device that can automatically insert lock heads on an automated production line.

The cylinder and the lock head feeding fingers can grasp the lock head perpendicularly to its axis, and then swing it upwards 180 degrees to move the grasped lock head to the opposite side of the push column. At this time, the lock head mounting seat moves towards the straight tube that is positioned to the left and right under the drive of the lock head pushing mechanism. The lock head held by the lock head feeding fingers can be shallowly inserted into the port of the straight tube under the drive of the lock head mounting seat. After the lock head feeding fingers release the end cover, the push column can push the lock head under the drive of the push drive mechanism, so that the lock head can be inserted into the port of the straight tube.

[0005] Furthermore, in the aforementioned pipe end lock assembly device: a correction clamping finger is provided on the frame inside the push column. A clamping block is fixed on each of the two clamping fingers of the correction clamping finger. The two clamping blocks are arranged front and back. A clamping groove is provided on the inner sidewall of the two clamping blocks respectively. An arc-shaped protrusion is provided in the outer port of the two clamping grooves respectively. A guide ramp is provided on the outer end face of the arc-shaped protrusion. Under the drive of the correction clamping finger, the two clamping blocks can clamp each other front and back. At this time, the two clamping grooves can position the straight pipe by clamping it on the end of the straight pipe. The two arc-shaped protrusions can be joined together to form a correction channel coaxial with the straight pipe and located outside the straight pipe port. During insertion, the lock head enters the correction channel under the guidance of the guide ramp. Then, the lock head can be smoothly inserted into the straight pipe port under the guidance of the correction channel.

[0006] Furthermore, in the aforementioned pipe end lock assembly device, two wide-shaped cylinder fingers arranged horizontally are provided on the frame, a backing plate and a backing drive mechanism that can drive the backing plate to move left and right. The straight pipe is supported and positioned on the frame by being clamped by the two wide-shaped cylinder fingers at both ends. The backing plate can be used for the straight pipe to abut when the lock is installed. The backing drive mechanism can drive the backing plate away from the straight pipe so as not to hinder the transfer of the straight pipe.

[0007] Furthermore, the aforementioned pipe end lock assembly device also includes a lock supply mechanism. The lock supply mechanism comprises a lock vibratory feeder for providing locks, a lock conveying channel on the vibratory feeder, and locks conveyed outward by the vibratory feeder sliding downward and arranging themselves in the lock conveying channel. Lock feeding fingers are located between the lock conveying channel and the push column. An avoidance notch is provided at the lower end of the lock conveying channel. The lock feeding fingers can pass through the avoidance notch to grip the first lock in the lock conveying channel from above and below. Furthermore, because the upper surface at the lower end of the lock conveying channel is open and the baffle at the lower port of the lock conveying channel is set as an arc-shaped plate that can avoid the locks, the lock feeding fingers can swing upward under the drive of the lock rotating cylinder and bring the gripped lock away from the lock conveying channel.

[0008] Furthermore, in the aforementioned pipe end lock assembly device, a lock stop block and a lock stop block driving mechanism are provided above the lower end of the lock delivery channel.
