[0031] The present invention will be further described below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0032] like Figure 2 As shown, a multi-faceted horizontal adjustment support device is used to clamp a workpiece 1, wherein the workpiece 1 is provided with four openings 11, and comprises: a support frame 2; an adjustment process ring 3, wherein the adjustment process ring 3 is coaxially welded and connected to the workpiece 1; an inclined plate 4, which is arranged on the upper part of the adjustment process ring 3, and the workpiece is located below the inclined plate 4, and the inclined plate 4 is connected to the adjustment process ring 3 by a threaded pair according to the distribution hole position; the workpiece 1, the adjustment process ring and the inclined plate are hoisted as a whole on the support frame 2, and one of the end faces of the opening of the workpiece 1 is made horizontal to the ground.

[0033] In a specific embodiment, the support frame includes: a first support member 21 arranged horizontally; and a second support member 22 arranged perpendicularly to the first support member.

[0034] A first hinge support 41 and a second hinge support 42 are respectively provided on two opposite sides of the inclined plate 4; the inclined plate is hinged to one end of the first support member 21 through the first hinge support 41, and the first hinge support 41 is used to limit the workpiece in the horizontal and vertical directions; the inclined plate 4 is also hinged to the top end of the second support member through the second hinge support 42, and the second hinge support 42 is used to limit the workpiece in the vertical direction. Figure 3A is a limiting diagram of the first hinge support, wherein the first hinge support 41 limits the -x and -y directions of the workpiece. Figure 3B This is a limiting diagram of the second hinge support, wherein the second hinge support 42 limits the workpiece in the -y direction.

[0035] The inclined plate 4 has two mutually perpendicular symmetry axes as cross scale lines 43, one of which is perpendicular to the side of the inclined plate where the first hinge support is provided, and the symmetry axis is set as the y-axis scale line of the cross scale line.

[0036] The outer end surface of the workpiece hole is provided with a cross line 12, and the cross line 12 is two vertical hole symmetry axes of the workpiece hole, one of which is located in the same vertical plane as the y-axis scale line, and the vertical plane is perpendicular to the horizontal plane.

[0037] In a specific embodiment, the device also includes a heightening block 5, which is arranged between the second hinge support 42 and the second support member 22.

The product and the adjustment process ring are coaxially welded and connected. According to the requirements of the four hole angles, the process ring distribution holes 31 on the process ring 3 are adjusted. In addition to arranging the corresponding connection holes on the adjustment process ring, the inclined plate will also mark a cross scale line (the cross scale line and the cross line y of the workpiece hole can be adjusted to the same vertical plane for mechanical connection according to the arrangement of the distribution holes), and according to the structural design, the axis of the bar 44 of the hinge support can be kept horizontal and vertical with the cross scale line on the inclined plate, and finally the following is obtained. Figure 6 The orifice axisymmetric connection parts. By adjusting the inclined plate 4, the threaded pair between the process rings is adjusted to fasten the connection integral parts, and then the parts are lifted and placed on the support frame.
