Abstract
The invention discloses a draw bar for guiding a copper tube to be inserted into a condenser fin. The draw bar can freely enter or retreat from an assembling hole in the condenser fin, and the draw bar comprises a bar body. The draw bar for guiding the copper tube to be inserted into the condenser fin is characterized in that the front end of the bar body is provided with a guide bar extending along the length direction of the bar body in a protruding mode; the guide bar can be used for the copper tube to be inserted in and the outer diameter of the guide bar is less than that of the bar body; and the front end of the guide bar is provided with a guide part which is convenient for the copper tube to be inserted in and the outer diameter of the guide part decreases gradually. The draw bar for guiding the copper tube to be inserted into the condenser fin provided by the invention is simple in structure, the end part of the copper tube can be smoothly inserted into the assembling hole of the condenser fin under the effect of the guide bar at the front end of the draw bar, and the production efficiency is improved.
Description
Technical field:
The present invention relates to a kind of draw bar for guiding in copper pipe insertion condenser fin.
Background technology:
The existing condenser be applied in air-conditioning, its copper pipe generally relies on plant working personnel manual operations to intert in fin, is difficult to like this ensure that copper pipe can once pass through all fins, and production efficiency is low.Therefore be necessary that providing a kind of can insert in the process of condenser fin the device that copper pipe can be guided to insert smoothly, to enhance productivity at copper pipe.
Be disclose a kind of guide rod in the patent of CN1302997A at publication number, this guide rod can freely enter or exit in the pilot hole on dull and stereotyped pin, it comprises the body of rod, and the front end of the body of rod is convexly equipped with the tip extended along its length, can be convenient to insert needle pin and external diameter and reduce gradually.The guidance part of this guide rod and the inwall of needle pin are linear contact lay, and in the process used, contact force is large not, so that are often separated with needle pin in guiding needle pin process, there is necessity of improvement.
Summary of the invention:
In order to solve the above problems, the invention provides a kind of draw bar for guiding in copper pipe insertion condenser fin, its structure is simple, copper pipe not only can be guided to insert smoothly in the pilot hole of condenser fin, enhance productivity, and in the process used, the no-float of draw bar and copper pipe, avoids both to be separated.
For this reason, the present invention adopts following scheme:
A kind of draw bar for guiding in copper pipe insertion condenser fin, this draw bar can freely enter or exit in the pilot hole on condenser fin, it comprises the body of rod, being provided with foremost of the body of rod is convenient to insert copper pipe and the diminishing guidance part of external diameter, guide bar is provided with between the described body of rod and guidance part, it is characterized in that: this guide bar extends along body of rod length direction, its external diameter compared with the body of rod little and on its extending direction equal diameter, guide bar can insert described copper pipe time contact with the inwall holding surface of copper pipe.
Structure of the present invention is simple, and the end of copper pipe, under the guide bar effect of draw bar front end, can be inserted in the pilot hole of condenser fin smoothly, enhance productivity, and in the process used, the no-float of draw bar and copper pipe, avoids both to be separated.
Described guidance part is taper guidance part, and structure is simple, is beneficial to copper pipe and inserts in the guide bar of draw bar smoothly, and final traction copper pipe inserts in the pilot hole of condenser fin smoothly.
Be provided with the diminishing connecting portion of external diameter between the described body of rod and guide bar, structure is simple.
Described connecting portion is truncated cone-shaped connecting portion, and this connecting portion is reduced gradually by the direction top external diameter of the body of rod to guide bar, and structure is simple.
Described guide bar and body of rod concentric are arranged, and structure is simple.
When described copper pipe inserts guide bar, the end of its insertion end is 12.5mm to the distance of described connecting portion.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the draw bar of the present invention.
Fig. 2 is that the draw bar of the present invention to enter in condenser fin and to guide copper pipe to insert the schematic diagram of the pilot hole of condenser fin smoothly.
Fig. 3 is the A portion enlarged drawing of Fig. 2.
Detailed description of the invention:
As shown in Figure 1, a kind of for guiding copper pipe 01 to insert draw bar 61 in condenser fin 02, this draw bar 61 can freely enter or exit in the pilot hole on condenser fin 02, it comprises the body of rod 611 and arranges with body of rod concentric and extend along body of rod length direction and be convexly equipped in the guide bar 612 of lever front end, this guide bar 612 can insert described copper pipe 01 and its external diameter is little compared with the body of rod 611, and the front end of guide bar 612 is also provided with to be convenient to insert copper pipe 01 and the diminishing taper guidance part 6120 of external diameter.Be provided with truncated cone-shaped connecting portion 613 between the described body of rod 611 and guide bar 612, this connecting portion 613 is reduced gradually by the direction top external diameter of the body of rod 611 to guide bar 612.
As shown in Figure 2,3, when described copper pipe 01 inserts guide bar 612, the end of its insertion end is 12.5mm to the distance d of described connecting portion 613, insert at this draw bar 61 in the process of guiding copper pipe 01, above-mentioned distance d can be kept and the pilot hole progressively exited on condenser fin 02 with progressively inserting of copper pipe 01.
The foregoing is only preferred embodiment of the present invention, be not used for limiting scope of the invention process, all equal changes of doing according to the scope of the claims of the present invention and modification, all fall into the scope that patent of the present invention contains.
