Description

Technical Field

[0001] This utility model relates to the field of shaft workpiece processing technology, and specifically to a shaft workpiece straightening device. Background Technology

[0002] Shaft-type workpieces will deform after heat treatment and forming. The straightness is generally not visible to the naked eye. The curvature needs to be checked with a wire gauge and then straightened with a straightening machine. If straightening is performed directly in one go, it is easy to break. It is necessary to straighten slowly with a straightening machine so that the shaft-type workpieces have good toughness.

[0003] In the prior art, when the straightening device straightens shaft-type workpieces, the shaft-type workpieces are supported by support seats. However, the support seats are usually fixed and cannot be adjusted according to the different lengths of the shaft-type workpieces. Alternatively, the support seats are not fixed and can be adjusted at will, but it is difficult to ensure that the support seats on both sides are on the same straight line. The shaft-type workpieces will be skewed during straightening, resulting in poor stability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a straightening device for shaft-type workpieces, which can solve the problems in the prior art where the support seats for shaft-type workpieces are fixed and cannot be adjusted in position, or are not fixed and it is difficult to ensure that the support seats on both sides are on the same straight line, resulting in skewing and poor stability when straightening shaft-type workpieces.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: it includes a workbench, a hydraulic mechanism and a support base, characterized in that: the hydraulic column of the hydraulic mechanism is located above the workbench, at least two support bases are provided on the top of the workbench, and a support block is provided directly below the hydraulic column and placed on the top of the workbench;

[0006] The support base has a V-shaped groove at the top center, the bottom of the V-shaped groove is flat, and a through hole is provided at the bottom of the V-shaped groove, through which a T-shaped column is inserted.

[0007] The top of the workbench is provided with a horizontal groove extending along the length of the workbench. The bottom of the T-shaped column extends out of the bottom end of the support base and into the horizontal groove. When the support base is moved to adjust its position, the T-shaped column moves in a straight line along the horizontal groove.

[0008] The support base is fixed by a limiting structure.

[0009] Furthermore, the top of the T-shaped column is supported on the bottom of the V-shaped groove, and the top of the T-shaped column is fixed to the support base by bolts.

[0010] Furthermore, the support base is provided with lifting lugs on both sides.

[0011] Furthermore, the limiting structure includes an inverted U-shaped limiting seat, the top center of which is provided with a slot for the support seat to pass through, and the two sides of the limiting seat are respectively provided on the outer sides of the two sides in the width direction of the workbench, and the limiting seat is locked onto the workbench.

[0012] Furthermore, the two sides of the limiting bracket are locked and fixed to the side of the worktable by locking bolts.

[0013] The advantages of this utility model after adopting the above structure are as follows: the support base supports the shaft workpiece, and the bottom of the support base is connected to a T-shaped column. When the position of the support base is adjusted according to the different lengths of the shaft workpiece, the position of the support base is adjusted along the length direction of the worktable, and the T-shaped column moves linearly along the horizontal groove on the worktable, so that the support base moves linearly, ensuring that different support bases always remain on the same straight line, the shaft workpiece is placed in a stable position, and no skewing occurs during straightening.

[0014] The support base is equipped with lifting lugs on its side for easy movement. The support base is positioned by a limiting structure, which makes it easy to fix the position of the support base after adjustment, resulting in good stability when straightening shaft-type workpieces.

[0019] like Figure 1 As shown, this specific embodiment adopts the following technical solution: it includes a workbench 1, a hydraulic mechanism 2, and a support base 3. The hydraulic column 21 of the hydraulic mechanism 2 is located above the workbench 1. An electric control console is installed on one side of the workbench 1. The electric control console is electrically connected to the hydraulic mechanism 2. At least two support bases 3 are provided on the top of the workbench 1. A support block 4 is located on the top of the workbench 1 directly below the hydraulic column 21. In this embodiment, two support bases 3 are provided, and the two support bases 3 are respectively located on the left and right sides of the support block 4.

[0020] like Figure 3As shown, a V-shaped groove 31 is provided at the top center of the support base 3. The bottom of the V-shaped groove 31 is flat. A through hole is provided at the bottom of the V-shaped groove 31. A T-shaped column 32 is inserted through the through hole. The top of the T-shaped column 32 is supported on the bottom of the V-shaped groove 31. The top of the T-shaped column 32 is fixed to the support base 3 by bolts. Lifting lugs 33 are provided on both sides of the support base 3. The lifting lugs 33 are provided to facilitate the movement of the support base 3.

[0021] like Figure 2 As shown, the top of the workbench 1 is provided with a horizontal groove 11 extending along the length of the workbench 1. The bottom of the T-shaped column 32 extends out of the bottom end of the support seat 3 and into the horizontal groove 11. When the support seat 3 is moved to adjust its position, the T-shaped column 32 moves in a straight line along the horizontal groove 11 to ensure that the support seat 3 moves horizontally. The support seats 3 on both sides are always on the same straight line and will not be tilted.

[0022] The support base 3 is fixed by a limiting structure, which includes an inverted U-shaped limiting bracket 5.

[0024] Working principle: When straightening shaft-type workpieces, the hydraulic column 21 of the hydraulic mechanism 2 is used to lift and straighten the shaft-type workpieces. The lower part of the straightening impact point is supported by the support block 4, and the bottom of the shaft-type workpiece is supported by the support seat 3. The bottom of the support seat 3 is connected to the T-shaped column 32. When adjusting the position of the support seat 3 according to the different lengths of the shaft-type workpieces, the support seat 3 is adjusted along the length direction of the worktable 1, and the T-shaped column 32 moves linearly along the horizontal groove 11 on the worktable 1, so that the support seat 3 moves in a straight line, ensuring that different support seats 3 always remain on the same straight line. The shaft-type workpieces are placed in a stable position and will not be skewed during straightening. The support seat 3 is provided with a lifting lug 33 on the side to facilitate the movement of the support seat 3.
