Abstract

The present invention relates to a pipe fixing jig, a first support having a chuck mounted thereon, a second support having a through hole, and a linear reciprocating motion in the through hole for fixing a lower arm regardless of pipe size (length and inner diameter). A jig consisting of a semi-circular fixing member having a movable bar and a long axis and a short radius can be easily inserted and fixed in the jig regardless of the size of the pipe connected to the frame by a pivot or the like. As a result, the cost and work process can be reduced, and the fixed pipe can be easily taken out as well as semi-permanently used for all vehicles.

The present invention relates to a pipe fixing jig, and more particularly, pipe size coupled to the frame by a jig for fixing the pipe at one end of a lower arm that absorbs up and down vibrations. This invention relates to a pipe fixing jig that can be fixed firmly to the lower arm regardless of the change of the gear and at the same time, the pipe can be easily detached from the jig.

In general, a lower arm for cushioning shocks or vibrations received from a road surface while driving a vehicle, in particular, upper and lower vibrations transmitted to a frame, is illustrated by a coupling means such as a pivot as shown in FIG. Pipe 11 is fixed at one end of the lower arm 10 by a suitable method such as welding.

As described above, the conventional fixing jig for fixing the pipe at one end of the lower arm has the first and second having a predetermined width W on the upper surface of the base 20 into which the pipe 11 is inserted, as shown in FIG. Supports 21 and 22 are vertically fixed, and through holes 21a having the same inner diameter D as the hollow portion 11a of the pipe 11 at substantially the center of the first and second supports 21 and 22. 22a are formed, and the nut 11 is fixed to the through-holes 21a and 22a and the hollow portion 11a of the pipe 11 so as to fix the pipe 11 and the lower arm 10 by welding. The bolt 24 to which the 23 is fastened is loosely fitted.

However, as described above, the jig for fixing the lower arm and the pipe has a constant width W between the first and second supports mounted on the upper surface of the base, so that the size of the pipe, that is, the length L or the inner diameter D is fixed. As the jig must be manufactured according to the change, the cost increases and the manufacturing process is added, which complicates the workmanship, and when the fixing is completed, the pipe must be taken out after loosening the nut fastened to the bolt. There was a cumbersome problem of attaching and detaching the pipe inserted into the jig during fixing.

The present invention has been made to solve the above problems, an object of the present invention is to provide a jig for fixing the pipe coupled to the frame by the pivot to the lower arm, to change the pipe size (length and inner diameter) Regardless, it can be easily inserted and fixed in the jig to reduce the cost and work process, to easily take out the pipe that has been fixed by welding, and to provide a pipe fixing jig that can be used for all kinds of vehicles.

Features of the pipe fixing jig according to the present invention for achieving the above object, the fixing jig for fixing the pipe by welding, etc. at one end of the lower arm is coupled to the frame by a pivot to cushion the vibration of the upper and lower direction In the above, regardless of the size of the pipe, a first support with a chuck mounted on the upper surface of the base for fixing the lower arm is installed vertically, and is installed on the same axis on one side of the first support to fix the pipe. A second support having a through hole formed therein, and a moving bar equipped with a tailstock at one end thereof is inserted into the through hole of the second support, and a fixing stand installed at one side of the second support to enable the reciprocating movement of the moving bar linearly; A semicircular fixing member having a long axis and a short radius is fixed and mounted on one side of the fixing member to rotate the fixing member. Key is in a point, characterized by consisting of a lever.

Hereinafter, a preferred embodiment of the pipe fixing jig according to the present invention will be described in detail with reference to the accompanying drawings.

3 and 4 is a view showing a pipe fixing jig according to the present invention, the first support 51 is vertically installed on the upper surface of the base 50, one side on one side of the first support 51 The plate is rotatably mounted to the chuck 52, and a second support 53 is provided on one side of the first support 51 with a through hole 53a formed in an axial line.

In addition, a moving bar 54 capable of linear reciprocation is inserted into the through hole 53a of the second support 53, and a conical tailstock 55 is mounted at one end of the moving bar 54. Another end is formed with a coupling hole (54a) so that the coupling pins 56 are fitted.

The semi-circular fixing member 58 having a radius of the major axis R and the minor axis R 'is fixed to the holder 57 provided at one side of the second support 53 so as to be rotatable by the shaft 59. The shaft 59 is fitted with a washer 60, a pin, or the like to prevent separation during the flow of the fixing member 58. In addition, one side of the fixing member 58 has an arc-shaped guide groove 58a having a different radius, and on one side, a lever 61 capable of rotating the fixing member 58 clockwise or counterclockwise is mounted. It is.

Referring to the operation of the pipe fixing jig according to the present invention configured as described above are as follows.

First, the pipe 11 fixed by welding is inserted between the 1st, 2nd support 53 installed perpendicular to a base. At this time, since the width W of the first and second supports 51 and 53 is wider than the length L and the inner diameter D of the pipe 11, the pipe 11 may be inserted regardless of the changed pipe 11 size. One surface of the pipe 11 is surely contacted with the flat surface of the chuck 52 mounted on one side of the first support 51.

Thereafter, when the lever 61 of the fixing member 58 rotatably mounted to the fixing table 57 is rotated counterclockwise, the outer circumferential surface of the fixing member 58 having a large radius R is moved to the moving bar 54. Straight line to the left direction to insert the tailstock 55 mounted on one end of the moving bar 54 into the hollow portion (11a) of the pipe (11) to firmly weld the lower arm (10) to the pipe (11) by welding Fix it.

That is, the moving bar 54 is separated from the short axis R 'of the semi-circular fixing member 58 rotating around the shaft 59 while the long axis R of the fixing member 58 approaches the moving bar 54. ) To the left.

On the other hand, in the case where the welded pipe is taken out from the jig, the fixing member is rotated clockwise by rotating the lever 61 mounted on the fixing member 58 in the reverse order when the pipe 11 is inserted into the jig. The 58 is rotated from the long axis R to the short axis R 'to be separated from one end of the moving bar 54, and at the same time, the moving bar 54 is pulled to the right to be inserted into the hollow portion 11a of the pipe 11. The pipe 11 may be easily taken out by detaching the tailstock 55.

As described above, according to the pipe fixing jig according to the present invention, the pipe fixed to the lower arm can be easily inserted and fixed in the jig regardless of the change of the pipe size (length and inner diameter) that is coupled to the frame by pivot, etc. And the work process is reduced, it is easy to take out the pipe is fixed by welding, as well as can be used semi-permanently in all models.
