Traditionally, after initial machining, continuous casting rollers were assembled manually. This resulted in a complex overall structure, particularly with the manual assembly of the roller sleeve and mandrel.

DETAILED DESCRIPTION

[0023] To better understand the present invention, the following examples further illustrate the present invention. However, the present invention is not limited to the following examples. In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be practiced without one or more of these details.

[0024] Example 1: See Figure 1-3 A universal assembly device for continuous casting rollers includes a body 1, a hydraulic device 2, a V-block moving platform 3, a top plate moving platform 4, a fixing layer 5 and a positioning pin 6;

[0025] The main body 1 is in the shape of a square groove, a hydraulic device 2 is fixedly provided at one end of the main body 1, a top plate moving platform 4 is provided at the other end, and the V-block moving platform 3 is provided between the top plate moving platform 4 and the hydraulic device 2;

[0026] A fixing layer 5 is integrally fixed to the inner side of the body 1. The fixing layer 5 is provided with a plurality of equidistant fixing layer positioning holes 54 with vertical axes along the length direction; both sides of the V-block moving platform 3 and the top plate moving platform 4 are also provided with platform positioning holes that match the fixing layer positioning holes 54;

[0027] The V-block moving platform 3 and the top plate moving platform 4 are both detachably fixedly connected to the main body via positioning pins 6 used in conjunction with positioning holes.

[0028] Slide rails 11 are provided on both sides of the inner lower surface of the main body 1 along the moving direction of the V-block moving platform 3. The V-block moving platform 3 and the top plate moving platform 4 are slidably connected to the main body 1 through fixed rollers 31 that cooperate with the slide rails 11.

[0029] Before assembly, the continuous casting roller is placed on the V-block moving platform 3, and the top plate moving platform 4 is aligned with the center of the roller sleeve. The positioning pin 6 passes through the internal side fixing layer 5 of the main body 1 and the positioning holes on both sides of the V-block moving platform 3 and the top plate moving platform 4 to achieve relative fixation of the V-block moving platform 3 and the top plate moving platform 4 with the main body 1. When it is necessary to adjust the relative positions of the V-block moving platform 3 and the top plate moving platform 4 with the main body 1 according to the continuous casting rollers of different length specifications, it is only necessary to pull out the positioning pin 6, move the V-block moving platform 3 and the top plate moving platform 4 to the appropriate position, and fix them with the positioning pin 6 again.

[0030] After the above work is completed, the mandrel is lifted by the crane and moved between the hydraulic device 2 and the roller sleeve. The mandrel is manually assisted to be in a horizontal state, and the chamfers of the mandrel end face and the inner hole of the roller sleeve are in a matched state to ensure that the mandrel and the roller sleeve are concentric. Then the hydraulic device 2 is aligned with the mandrel, and the mandrel is pushed by the hydraulic device 2 to complete the interference fit of the mandrel and the roller sleeve.

[0031] This method realizes that the position of the movable platform and the main body can be quickly adjusted according to the continuous casting rollers of different lengths and specifications to adapt to the continuous casting rollers of different lengths, thereby improving the assembly accuracy and the work efficiency.

[0032] Example 2: See Figure 4-6 The universal assembly device for continuous casting rollers provided in this embodiment is improved as follows based on the first embodiment:

[0033] Furthermore, the fixed layer 5 is at least 3 layers, including a first fixed layer 51, a second fixed layer 52, and a third fixed layer 53; the platform positioning holes opened on both sides of the V-block moving platform 3 and the top plate moving platform 4 include an upper positioning hole 71 and a lower positioning hole 72; the fixed layer positioning hole 54 vertically passes through the first fixed layer 51, the second fixed layer 52 and the third fixed layer 53, the upper positioning hole 71 is located between the first fixed layer 51 and the second fixed layer 52, and the lower positioning hole 72 is located on the upper side of the third fixed layer 53.

[0034] This method adopts a multi-layer positioning design, and the upper positioning hole 71 and the lower positioning hole 72 are fixed to the fixing layer 5 by a positioning pin 6 at the same time, which further reduces the occurrence of frame volume, thereby improving assembly accuracy and improving yield rate.

[0035] Furthermore, the V-shaped support block on the V-shaped moving platform is a double V-shaped structure, with two V-shaped support blocks 32 arranged front and back along the moving direction, and the V-shaped support blocks are detachably fixedly connected to the V-shaped moving platform.

[0036] The V-shaped support block 32 adopts a double V-shaped structure, which enhances the supporting stability of the V-shaped support block 32. During the installation process, the self-centering effect of the V-shaped support block 32 ensures that the roller sleeve is level. The V-shaped support block 32 is detachably fixedly connected to the V-shaped block moving platform 3. According to the continuous casting rollers of different diameters and specifications, the V-shaped support block 32 matching the diameter can be replaced to keep the roller sleeve, the core shaft center and the upper positioning hole and positioning pin fixed connection of the top plate moving platform level, so that the force is more uniform, thereby further improving the assembly accuracy.

[0037] In addition, according to the different length and size specifications of the continuous casting roller, several V-block moving platforms can be selected to jointly provide support for the continuous casting roller.

[0038] Furthermore, the tail end of the positioning pin 6 is hemispherical.

[0039] The use of this hemispherical positioning pin 6 can play a guiding role when the positioning pin 6 enters the multi-layer positioning hole, so that the positioning pin 6 can be inserted into the positioning hole more easily, conveniently and quickly.

[0040] Example 3: See Figure 7 The universal assembly device for continuous casting rollers provided in this embodiment is improved as follows based on the second embodiment:

[0041] Furthermore, an electric telescopic bidirectional synchronous push rod 8 is fixedly installed between the third fixed layer 53 and the lower positioning hole 72 on both sides of the V-block moving platform 3 and the top plate moving platform 4; the upper and lower output shaft ends of the electric telescopic bidirectional synchronous push rod 8 are detachably connected with positioning pins 6.

[0042] In Example 2, during operation, the mandrel, roller sleeve axis, and top plate movable platform upper locating hole are horizontal. Therefore, the locating pins are subjected to significant forces at the top plate movable platform upper locating hole, which can easily cause wear. This embodiment utilizes a motorized, retractable, bidirectional synchronous push rod to create a dual-position locating pin operation mode. This allows for individual replacement of the locating pins based on their wear, saving on vulnerable workpiece material.

[0043] Moreover, this method only requires manual confirmation that the upper positioning holes 71 and the lower positioning holes 72 on both sides of the V-block moving platform 3 and the top plate moving platform 4, the fixed layer positioning holes 54, and the positioning pins 6 on the electric telescopic bidirectional synchronous push rod 8 are all in a coaxial state. The positioning pins 6 can be quickly inserted into the positioning holes for fixation by controlling the electric telescopic bidirectional synchronous push rod 8, and the position of the moving platform and the main body can be quickly adjusted according to the continuous casting rollers of different lengths and sizes, thereby improving the work efficiency of adapting to continuous casting rollers of different lengths and reducing manual labor participation.

[0044] The utility model solves the problem of rework caused by quality problems of rollers during manual assembly, and when encountering continuous casting rollers of different lengths, sizes and specifications, the device can be quickly and efficiently adjusted as needed to adapt to continuous casting rollers of different lengths, sizes and diameters, which is efficient, reduces the burden of manpower and is easy to operate; and in the process of roller assembly and extrusion, the locating pins in the device bear a large amount of action and reaction force, and the locating pins are detachable connection mode, so that the locating pins can be replaced under appropriate circumstances according to the deformation of the locating pins, thereby reducing the occurrence of frame loss, thereby improving assembly accuracy and improving the yield rate.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
