[0002] The machine tool feed structure is the feeding motion part of the machine tool and one of the important components of the machine tool. The machine tool feed structure is a mechanism that changes the feed amount during machine tool cutting or changes the relative motion relationship between the tool and the workpiece during surface forming motion. The main function of the machine tool feed structure is to move the workpiece to the processing position for processing;

[0003] The accuracy of the machine tool feed mechanism determines the machining quality of the machine tool, and is also one of the important factors to ensure the surface quality, size and shape stability of the workpiece. When the general machine tool feed mechanism drives the tool assembly to move along the guide rail by contracting the drive assembly, the guide rail can only constrain the horizontal direction of one side of the tool holder, and the horizontal direction of one side of the tool holder is generally not constrained, which makes it easy for the machine tool feed mechanism to drive the tool assembly to move. Torsion swing phenomenon occurs. Therefore, we propose a machine tool feed structure. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a machine tool feeding structure, including a machine tool body and a first guide rail, the upper side of the machine tool body is respectively fixed with a first guide rail and a second guide rail, the upper side of the first guide rail and the upper side of the second guide rail are simultaneously installed with a contraction drive assembly, and the contraction drive assembly includes a contraction folding displacement cover and a drive motor, the contraction folding displacement cover of the contraction drive assembly is installed with a tool assembly, and the tool assembly includes a tool holder and a vertical arm, the tool holder and the vertical arm of the tool assembly are fixed by bolts, the lower side of the first guide rail is fixed with a first tooth plate, and the lower side of the second guide rail is fixed with a second tooth plate.

[0008] Preferably, the second tooth plate is connected to the second gear, and the second gear is movably connected to one side of the contraction drive assembly through a bearing rod.

[0009] Preferably, a support plate is fixed to the machine tool body below the contraction drive assembly, and a support roller is provided on the upper side of the support plate.

[0010] Preferably, a sliding rod is fixed to the lower side of the support roller, and a side of the support roller close to the sliding rod is fixed to a limiting screw.

[0011] Preferably, the sliding rod and the support plate are slidably penetrated, the limiting screw penetrates and extends out of the interior of the first bevel gear, and the first bevel gear is movably connected to the support plate through a bearing.

[0012] Preferably, the first bevel gear is connected to the second bevel gear, and the second bevel gear is movably connected to the support plate via a bearing.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the machine tool feeding structure starts the driving motor of the power assembly, so that the first gear moves along the first tooth plate, and the second gear moves along the second tooth plate at the same time, and the first guide rail and the second guide rail constrain the retraction drive assembly, so that the machine tool feeding mechanism can solve the problem of machine tool torsion from the perspective of power and the perspective of the bed constraint guide rail, rotate the center rod of the second bevel gear, so that the support roller lifts the retraction drive assembly, so that the support roller assists in supporting one side of the retracted and folded displacement cover of the retraction drive assembly, so that the machine tool feeding structure is easy to maintain stability.

[0014] 1. The feeding structure of the machine tool, the accuracy of the feeding mechanism of the machine tool determines the processing quality of the machine tool, and is also one of the important factors to ensure the surface quality, size and shape stability of the workpiece. When the feeding mechanism of the machine tool needs to drive the tool assembly to move through the contraction drive assembly, the driving motor of the power assembly is started, so that the power assembly drives the first gear to rotate, so that when the first gear moves along the first tooth plate, the second gear moves along the second tooth plate at the same time, and the first guide rail and the second guide rail are constrained when the contraction and folding displacement cover of the contraction drive assembly moves, so that the feeding mechanism of the machine tool can solve the problem of machine tool torsion from the perspective of power and the perspective of the bed constraint guide rail;

[0015] 2. When processing a workpiece with a large diameter, the tool holder of the machine tool feeding structure moves to one side of the shrinking drive assembly, causing the shrinking and folding displacement cover of the shrinking drive assembly to be subjected to unbalanced force. At this time, the center rod of the second bevel gear can be rotated to allow the limiting screw to move upward along the first bevel gear to push the support roller upward, causing the support roller to lift the shrinking drive assembly, thereby providing auxiliary support to one side of the shrinking and folding displacement cover of the shrinking drive assembly, thereby facilitating the machine tool feeding structure to remain stable.
