Replaceable fluid supply device

The present invention relates to a fluid supply device, and more particularly to a replaceable fluid supply device.

Generally, when two metal objects are to be combined, the most commonly used combination method is achieved through a welding machine, and during the welding work of the welding machine, and because of different welding parameters, it must be regularly passed by the operator. Change the various welding gas and cooling liquid.

However, such manual replacement is not only time-consuming and labor-intensive, but also results in slow production and low production efficiency. Therefore, how to design a fluid supply device which can improve the above-mentioned technology to provide for use in a welding machine is an urgent problem to be solved.

It is an object of the present invention to provide an alternative fluid supply device that simplifies the replacement process and thus enables a quick change operation.

In order to achieve the above object, the present invention provides an alternative fluid supply device comprising a fixing base, a detachable module and at least one pivoting arm, the fixing seat is provided with a plurality of through holes; the detachable module pair The fixing base should be combined, and the detachable module is provided with a plurality of connecting the respective through holes a connecting hole, and a protruding post is connected to a side of the detachable module; the pivoting arm is pivotally connected to one side of the fixing seat, and a guiding member for rotating and fastening the protruding post is opened on the pivoting arm Groove.

The invention also has the following effects. By modular design of the detachable module, it is possible to eliminate the complicated procedure that must be detached after each pipe is removed one by one. The rolling contact of the roller and the swing arm can achieve a labor-saving effect. By means of the setting of the jacking portion, when the swinging arm is rotated, the detachable module can be simultaneously pushed up to be easily disengaged.

The detailed description and technical content of the present invention are set forth in the accompanying drawings.

Referring to FIG. 1 to FIG. 3, the present invention provides an alternative fluid supply device that can be applied to a welding machine 7, but without such a machine as a limitation, the replaceable fluid supply device 1 The utility model mainly comprises a fixing base 10, a detachable module 20 and a swinging arm 30.

The fixing base 10 is made of a metal or the like, and is substantially a rectangular block. Two rows of juxtaposed plurality of through holes 11 are formed in the fixing base 10, and a recess 12 is formed in the outer periphery of each of the through holes 11. The recess 12 is provided with a sealing ring 13 (see FIG. 5), and a positioning pin 14 is respectively connected to the front and rear sides of each of the rows of through holes 11. Further, a screw hole is respectively arranged on the left and right sides of the fixing base 10. 15.

The detachable module 20 is also made of a material such as metal, which is combined with the fixing base 10, and a plurality of docking holes 21 corresponding to the respective through holes 11 are opened in the detachable module 20, and the docking holes 2 are arranged in the rows. A positioning hole 22 is formed in the front and rear sides of the detachable module 20, and a protrusion 23 is connected to the left and right sides of the detachable module 20, and the protrusion 23 of the embodiment is provided by a roller 231. The utility model is composed of a screw 232. The screw 232 is inserted into the roller 231 and then screwed to the side of the detachable module 20.

The pivoting arm 30 can be a single branch, or can be a double-supported type as in this embodiment. The swinging arm 30 mainly includes a holding portion 31, a pivoting portion 32 extending from the holding portion 31, and A hook portion 33 extending from the pivoting portion 32 defines a guiding slot 34 between the pivoting portion 32 and the hook portion 33. The guiding slot 34 has an arc shape and is located in the middle of the pivoting portion 32. A through hole 35 is defined, and a rising portion 36 is formed on a side of the guiding groove 34 adjacent to the pivoting portion 32. The lifting portion 36 is in rolling contact corresponding to the aforementioned roller 231. The pivoting arm 30 is inserted into the screw hole 13 of the fixing base 10 through a bolt 37 and then screwed into the screw hole 13 of the fixing base 10 to achieve a pivotal joint of the swing arm 30 and the fixing base 10. The swing arm 30 of the present embodiment further includes a connecting rod 38 which is connected to the end position of each grip section 31 through a screw.

Referring to FIG. 4 to FIG. 5, the alternative fluid supply device of the present invention further includes a plurality of delivery tubes 40. The two ends of the upper delivery tube 40 respectively communicate with the docking holes 21 of the detachable module 20 and a fluid supply source 8. (See Fig. 1), the two ends of the lower conveying pipe 40 respectively communicate with the through hole 11 of the fixing base 10 and the welding machine 7 (see Fig. 1), and the fluid supplied from the fluid supply source 8 may be a gas or a liquid, wherein the gas is provided For welding purposes, the liquid is supplied to the welded object for cooling and cooling.
