Detailed Description

The utility model is described below with reference to the accompanying drawings.

Figure 1 shows an automated thread application apparatus 100 according to one embodiment of the present invention. As shown in fig. 1, the automatic thread coating device 100 includes a grease filling head 10, and a reservoir 20 for containing a grease filling liquid is defined in the grease filling head 10. Meanwhile, a first channel 30 for communicating the reservoir 20 with the space outside the grease filling head 10 is further provided on the grease filling head 10. Thereby, the fluid in the reservoir 20 is allowed to flow out to the space outside the grease filling head 10 through the first passage 30.

A grease injection pump (not shown) is disposed inside the grease injection head 10, and the grease injection pump is used for discharging grease injection liquid in the reservoir 20 from the first passage 30. Meanwhile, the grease injection pump is further connected with an electric control device 15, the electric control device 15 can control the opening time and the grease injection pressure of the grease injection pump, so that the smearing time and the smearing quantity of grease injection liquid are adjusted according to the working conditions of different pipe body screw threads, and the grease injection liquid is smeared on the screw threads of the pipe body uniformly and quantitatively.

As shown in fig. 1, the automatic thread coating device 100 further includes a slide rail 40. The grease filling head 10 is connected to the slide rail 40 so that the grease filling head 10 can move on the slide rail 40. Thus, the slide rail 40 can be arranged along the axial direction of a pipe body (not shown) to be painted, so that the grease injection head 10 extends into the pipe body along the axial direction of the pipe body during moving along the slide rail 40, and then reaches the thread at the end of the pipe body and contacts with the thread (not shown) at the thread. At this time, the space outside the grease injection head 10 can be communicated with the thread at the pipe body thread, and the grease injection liquid in the reservoir 20 can reach the pipe body thread when flowing out, thereby realizing the smearing operation of the pipe body thread.

Meanwhile, a first power device 12 is connected to the grease filling head 10, and the first power device 12 may be a direct-acting cylinder, for example. The first power device 12 provides power to control the grease injection head 10 to move.

In a preferred embodiment, a stopper 42 is further disposed on the slide rail 40. The limiting member 42 is disposed on a side of the slide rail 42 away from the grease filling head 10, and is configured to protrude from a step portion of the slide rail 40, so as to be capable of abutting against the grease filling head 10 to fix the position of the grease filling head 10, thereby playing a role in limiting. The position of the position limiting member 42 can be adjusted by sliding the position limiting member 42 on the slide rail 40.

It is easy to understand that the position of the limiting member 42 is adjusted to enable the grease filling head 10 to be engaged with the limiting member 42 at a predetermined position, so as to limit the grease filling head 10 from continuously sliding. Thus, the limit member 42 can adjust the stroke range of the grease filling head 10 on the slide rail 40 according to different field conditions. Preferably, the stepped portion is preferably configured to be tapered, so as to ensure that the limiting member 42 has a better clamping and limiting effect.

In a preferred embodiment, a micro switch 44 capable of controlling the movement of the limiting member 42 is further disposed on the limiting member 42, and the micro switch is disposed on a side of the limiting member 42 away from the grease filling head 10. When the limiting member 42 slides to a position where it contacts with a tube to be coated, the pressure of the tube to be coated on the limiting member 42 acts on the micro switch 44, so that the micro switch 44 is turned off. At this time, the stopper 42 stops moving. The limit stop 42 can be autonomously stopped in contact with the tube to be applied by means of a microswitch 44.

Besides, the automatic thread coating device 100 further comprises a base 50, and the base 50 is used for fixing the coating device 100. A transmission device 60 is further arranged between the base 50 and the slide rail 40, and the base 50 is connected with the slide rail 40 through the transmission device 60.

As shown in fig. 1, the transmission 60 includes a first arm 62 and a second arm 64 connected to the base 50 and the slide rail 40, respectively. The first arm 62 is hinged to the base 50 and the second arm 64 through a first connecting shaft 63 and a second connecting shaft 65. When the automatic thread coating device 100 is in the non-operating initial state, the first arm 62 and the second arm 64 are in the vertical state parallel to the slide rail 40. The horizontal distance between the slide rail 40 and the base 50 is at a minimum.

Fig. 2 is a schematic view of the automatic thread coating apparatus 100 shown in fig. 1 in an operating state. As shown in fig. 2, when the automatic thread gluing device 100 is in an operating state, the worker can adjust the angle of the first arm body 62 and the second arm body 64 with respect to the vertical direction by rotating the first connecting shaft 63 and the second connecting shaft 65, so that the first arm body 62 and the second arm body 64 are formed in a substantially "V" shaped configuration. In this way, the width of the transmission device 60 can be adjusted, so as to adjust the position of the slide rail 40 in the horizontal direction, and the grease injecting head 10 is opposite to the radial center of the pipe body to be coated.

As shown in fig. 2, a connecting rod 66 is also provided on the transmission 60. The two ends of the connecting rod 66 are respectively connected to the axial middle parts of the first arm body 62 and the second arm body 64. The connecting rod 66 is provided as a telescopic rod, so that the included angle between the first arm 62 and the second arm 64 can be adjusted quantitatively by adjusting the length control of the connecting rod 66. Meanwhile, a second power device 68 is also provided on the connecting rod 66. The second power unit 68 is, for example, a direct acting cylinder. Thus, the length of the adjusting link 66 can be adjusted by extending or retracting the second power device 68, so as to automatically adjust the included angle between the first arm 62 and the second arm 64.

In a preferred embodiment, the second arm 64 is also hinged to the slide 40 by means of a connecting element 69. After the position of the slide rail 40 is adjusted by the transmission device 60, the included angle between the slide rail 40 and the horizontal direction, that is, the included angle between the grease filling head 10 and the horizontal direction, can be adjusted by rotating the slide rail 40. Thereby enabling the automatic thread coating device 100 to be adapted to tubes of different angles.

Fig. 3 is a schematic view of the grease filling head 10 of the automatic thread coating apparatus 100 shown in fig. 1. As shown in fig. 3, the first passage 30 is configured as a through hole 32 provided on the outer wall of the grease filling head 10. The through-hole 32 communicates with the reservoir 20 such that the reservoir 20 can flow out through the through-hole. Preferably, a plurality of the through holes 32 are uniformly provided in the outer wall of the grease injection head 10 in the circumferential direction. Through the arrangement, the uniform coating of the pipe thread can be facilitated.

The operation of the automatic thread coating apparatus 100 according to the present invention is briefly described below.
