Description

Device for gluing circumferential surface of pipe fitting

Technical Field

The invention relates to the technical field of pipe fitting processing, in particular to a device for gluing the peripheral surface of a pipe fitting.

Background

At present, the gluing of the pipe fitting has two modes of manual gluing and plug-in gluing. Wherein, the manual glue spreading is to brush the surface of the pipe fitting by a tool such as a brush, so that the glue is uniformly spread on the surface of the pipe fitting. The characteristics of this mode are: the operation is flexible, but in the actual production process, because the small brush is used for gluing, the glue can not drip to the ground, and can drip on a table top and clothes carelessly, the cleaning is difficult, and the benefit can not be improved. Meanwhile, the black glue is easy to solidify, and needs to be diluted once by adding acetone every hour in the using process, and needs to be stirred constantly, the acetone has strong volatility and pungent smell, and the working area and the periphery are always accompanied with irritant gases, so that the working environment and the comfort level are influenced to a certain degree.

For the plug-in gluing mode, the end of the pipe fitting is inserted into a container filled with glue, and the insertion depth is the length of the glue brushing. The plug-in gluing mode needs to install a sleeve at the head of the pipe (one end of the sleeve is provided with an opening, the other end of the sleeve is closed) to prevent glue from entering the pipe, after the pipe is inserted into the glue, the surfaces of the pipe and the sleeve are covered with the glue, after the pipe is pulled out of the glue, the sleeve needs to be pulled out of the pipe, the process is complicated, the sleeve stuck with the glue cannot be reused, material waste is caused, and production cost saving is not facilitated.

For the above embodiment, the device further includes a swing blocking mechanism, which limits the glued end of the pipe fitting a clamped by the chuck 4, so as to control the glue brushing position of the pipe fitting a. Since the gluing part of the tube a is generally in a defined area, gluing failures can occur if the actual gluing location does not coincide with the defined gluing area. Therefore, the end parts of the pipe fittings A are limited and blocked by the swing blocking mechanism, and the glue feeding position of the glue feeding mechanism is unchanged relative to the pipe fittings A, so that for each pipe fitting A, glue fed to the pipe fitting A by the glue feeding mechanism is in a specified area, the glue coating mechanism is also in a specified position, and when the pipe fittings A rotate, the coated glue is in the specified area.

As shown in figure 1, before gluing, the swing arm 20 swings to reach the limiting position of the pipe fitting A, so that the end of the swing arm 20 is limited, and after the pipe fitting is clamped by the chuck 4, the swing arm 20 is driven to reset by the swing arm driving mechanism.

As shown in fig. 1, the pipe gluing device further comprises a second driving mechanism, wherein the power output end of the second driving mechanism is connected with the mounting base, and the second driving mechanism drives the mounting base to move, so that the gluing working position of the gluing mechanism corresponds to a gluing part required by the pipe fitting. The second driving mechanism comprises a second cylinder 23, a first slide rail 24 and a first slide block 25, the mounting seat body 16 is fixed with the first slide block 25, the first slide block 25 is matched with the first slide rail 24, and the second cylinder 23 is connected with the mounting seat body 16 or the first slide block 25.

As shown in fig. 1, after the swing blocking mechanism is arranged, since the position of the end of the pipe a is limited by the swing blocking mechanism, if the gluing working position of the gluing mechanism is at the working position, when the swing arm 20 swings to reach the limit position of the pipe a, the swing arm 20 is likely to collide with the gluing working position of the gluing mechanism, so as to avoid this, before the swing arm 20 swings to reach the limit position of the pipe a, the mounting base is driven by the second driving mechanism to drive the gluing mechanism to move right (right side shown in fig. 1) to make room for the swing arm 20 to swing to the designated position, when the swing arm 20 successfully limits the end of the pipe a and the pipe a is clamped by the chuck 4, the swing arm 20 resets, and at this time, the mounting base is driven by the second driving mechanism to drive the gluing mechanism to move left (working side shown in fig. 1), thereby leading the gluing working position of the gluing mechanism to reach the gluing working position.

The working process of the invention is as follows:

as shown in fig. 1 to 8, the second motor 22a operates to drive the swing arm 20 to swing to a limit position for the pipe fitting a through the second gear 22 and the first gear 21, and to sequentially pass one end of the pipe fitting a through the hollow shaft 3 and the chuck 4, and the end of the pipe fitting a contacts with the swing arm 20, so that the pipe fitting a is limited by the swing arm 20. The pipe fitting a is clamped by the chuck of the chuck 4, and the second motor 22a drives the second gear 22 and the first gear 21 to reset the swing arm 20, so that the swing arm 20 releases the limit on the end of the pipe fitting a. And opening the glue dispensing valve 7 to enable glue to drip on the pipe fitting A. The second cylinder 23 operates to drive the mounting seat body 16 to move leftward (as viewed in fig. 1), so that the mounting seat body 16 drives the connecting shaft 17 and the gluing mechanism to move leftward.

The linear actuator 14 is operated to rotate the rotating disc 10, and the rotating disc 10 rotates to drive the first connecting part 13 to move along the third through hole 11b, so that the first connecting part 13 drives the first sliding block 12 to move along the guiding slot 11a, and the painting assembly moves towards the center of the first sliding block seat 11. When the squeegee assembly is moved to a designated position (there is a gap between the squeegee assembly and the peripheral surface of the pipe a), the linear actuator 14 stops. At this time, the first motor 5 is operated to drive the chuck 4 to rotate through the first driving wheel 6, so that the pipe a rotates, and the glue dripping on the pipe a is coated by the coating component during the rotation of the pipe a.
