[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0025] See also Figure 1 and 2 As shown, the utility model is an adjustable tool for assembling shaft parts, including a base 1, four rollers 101 are connected to the lower side of the base 1, a support base 2 is connected to the upper side of the base 1, and the support base 2 is connected to a pair of roller frames 201, and the shaft parts are supported by the two roller frames 201, and the rollers installed on the roller frames 201 are rubber rollers.

[0026] like Figure 1 and 6 As shown, the rolling direction of the four rollers 101 connected to the base 1 can be parallel to the axial direction of the supported shaft part 6, which is convenient for axial movement of the shaft part 6, or the rolling direction of the rollers 101 can be perpendicular to the axial direction of the supported shaft part 6, which is convenient for lateral movement of the shaft part 6, so that a flexible selection can be made according to the specific position where the shaft part 6 is to be assembled.

[0027] like Figures 3-5As shown, the base 1 is fixedly connected to two guide posts 102, which are movably interlocked with the support base 2. A telescopic mechanism is provided between the base 1 and the support base 2. A piston cavity 103 is defined on the top surface of the base 1, and an oil passage 104 is defined on the side surface, communicating with the piston cavity 103. The telescopic mechanism includes a piston rod assembly 3 that engages with the piston cavity 103, and a piston cavity cover 301 connected to the top surface of the base 1.

[0028] The upper end of the piston rod assembly 3 passes through the piston chamber cover 301 and is connected to the support seat 2. The piston rod assembly 3 and the piston chamber cover 301 are sealed. The hydraulic system is connected to the oil channel 104 through a pipeline. The hydraulic pressure is used to enable the piston rod assembly 3 to move axially, thereby adjusting the upper and lower positions of the support seat 2 through the piston rod assembly 3, thereby adjusting the height of the supported shaft parts, which effectively helps to improve the overall assembly convenience.

[0029] And, as Figure 1 、 2 As shown in FIG4 , a vertically arranged scale 4 is fixedly connected to the side of the support base 2, and is used to determine the height of the support base 2 relative to the base 1 by means of the scale 4. When the shaft part 6 is supported by two fixtures, when the height of the shaft part 6 needs to be raised, in order to ensure that the heights of both ends of the shaft part 6 are consistent, the position of the upper edge of the base 1 and the corresponding scale position on the scale 4 after the support base 2 is raised can be observed, and the raised heights of the support bases 2 of the two fixtures can be accurately ensured to be consistent, thereby making the position of the shaft part 6 more accurate during assembly and ensuring the convenience of assembly.

[0030] At the same time, one of the two roller frames 201 is fixedly connected to the support seat 2, and the other roller frame 201 is slidably connected to the support seat 2, such as through a guide rail slider, or through a sliding fit between a slider and a slide groove.

[0031] The support seat 2 is rotatably connected to a screw rod 5, and the roller frame 201 slidably connected to the support seat 2 is provided with a threaded hole that cooperates with the screw rod 5. A clamping part is provided at one end of the screw rod 5, which is convenient for clamping and rotating by a wrench. It can also be directly connected to the motor transmission and driven to rotate by the motor.

[0032] By rotating the screw rod 5, the roller frame 201 connected thereto is moved, thereby adjusting the distance between the two roller frames 201 to accommodate shaft components of different diameters, making the support for the shaft components more stable and reliable.

[0033] In addition, the side of the support base 2 is provided with a scale 202 along the sliding direction of the roller frame 201, and the roller frame 201 is provided with an alignment mark to facilitate more accurate judgment of the moving position of the roller frame 201. The scale 202 is used to mark the diameter size of the shaft component adapted to the position where the roller frame 201 moves.

[0034] That is, the value of the scale 202 is the diameter of the shaft part. Therefore, after knowing the diameter of the shaft part 6 to be assembled, the roller frame 201 can be directly moved to the alignment mark and the scale position on the scale 202 that is equal to the diameter of the shaft part 6. This avoids the shaft part 6 from getting stuck or colliding with the support seat 2 due to the large distance between the two roller frames 201, and avoids the support stability from being affected due to the small distance between the two roller frames 201. Therefore, by setting the scale 202, the position of the roller frame 201 can be accurately adjusted according to the diameter of the shaft part 6 to be supported, thereby ensuring better support stability for the shaft part 6.
