Description

Technical Field

[0001] The utility model relates to the field of screw rod straightening equipment, in particular to a long screw rod straightening machine. Background Art

[0002] Currently, long lead screw straightening machines place the lead screw on two V-blocks, pressing down on the side that's not straight. Because there are only two V-blocks, the unsupported lead screw sags due to its own weight, affecting the overall accuracy of the lead screw. When the long lead screw needs to be moved for calibration, it must be manually lifted to prevent sliding friction between the lead screw and the V-blocks, affecting work efficiency. Furthermore, manual lifting of the lead screw is inconvenient when it's too heavy, and it can easily collide with the V-blocks. Summary of the Invention

[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0031] First, combine Figures 1 to 4 The long screw rod straightening machine according to the embodiment of the present invention is described, which is used in the screw rod straightening industry and has a wide range of application scenarios.

[0032] like Figures 1 to 4 As shown, the long lead screw straightening machine of the embodiment of the present invention comprises:

[0033] Support base 1, on which a linear guide rail 11 is provided;

[0034] A plurality of support columns 2, wherein the tops of the plurality of support columns 2 are connected to the support base 1;

[0035] Six V-blocks 3 are respectively slidably connected to the linear guide rails 11 to support the screw rod 6. The position of the V-block 3 on the linear guide rails 11 is adjustable; the six V-blocks 3 can greatly increase the support points and prevent the screw rod 6 from being deformed due to its own gravity.

[0036] The pressure rod mechanism 4 is arranged on one side of the support base 1 and is used to press the straight screw rod 6;

[0037] A plurality of lifting mechanisms 5 are sequentially arranged on the support base 1 for lifting the screw rod 6 .

[0038] Further, if Figures 1 and 2 As shown, in this embodiment, the support base 1 is an I-beam structure, which can be better designed as a calibration plane.

[0039] Further, if Figure 1 As shown, in this embodiment, the support column 2 is height-adjustable.

[0040] Further, if Figure 2 As shown, in this embodiment, the V-block 3 is slidably connected to the linear guide rail 11 through a slider, and the slider can be locked with the linear guide rail 11.

[0041] Further, if Figure 2 As shown, in this embodiment, the pressure rod mechanism 4 includes: a fixed plate 41, a support rod 42, a pressure rod 43 and a pressure block 44;

[0042] The fixing plate 41 is fixedly connected to the support base 1;

[0043] The support rod 42 is connected to the fixing plate 41;

[0044] The pressure rod 43 is hinged to the support rod 42;

[0045] The pressing block 44 is connected to the pressing rod 43 .

[0046] Further, if Figure 2 As shown, in this embodiment, the pressing block 44 is made of brass to prevent the pressing block 44 from damaging the screw rod 6.

[0047] Further, if Figures 2-4 As shown, in this embodiment, the lifting mechanism 5 includes: a fixed seat 51, a right-angle pressure rod 52 and a pulley 53;

[0048] The fixing base 51 is detachably connected to the supporting base 1;

[0049] The support angle pressure rod 43 is hinged to the fixing seat 51;

[0050] The pulley 53 is hinged to the right-angle pressure rod 52. When the right-angle pressure rod 52 is rotated, the pulley 53 can contact the screw rod 6 and lift the screw rod 6. The pulley 53 greatly reduces the friction during the movement of the screw rod 6.

[0051] The pulley 53 is provided with a limiting groove 531 for accommodating the screw rod 6 .

[0052] Further, if Figure 3 As shown, in this embodiment, a circular arc portion 521 is provided at the corner of the right-angle pressure rod 52, and a circular arc groove 511 is provided on the fixing seat 51. The circular arc portion 521 is slidingly coupled with the circular arc groove 511.
