DETAILED DESCRIPTION

[0016] The present invention is further described in detail below through specific embodiments:

[0017] like Figure 1 As shown, an embodiment of the present invention proposes a horizontal shrink fit tooling, comprising a base 1 fixed on the ground, the base 1 is fixedly connected to the ground by a plurality of screws, a workbench 2 is abutted against the top of the base 1 by a plurality of telescopic support frames, a plurality of movable adjustment frames circumferentially arranged on the outside of the workbench 2 are arranged on the base 1, a slide is slidably arranged on the workbench 2 along the X-axis direction, the top of the slide is used to support the driving shaft or the driven shaft arranged along the X-axis, and a push rod assembly detachably connected to one end of the driving shaft or the driven shaft is connected to the workbench 2;

[0018] Among them, the multiple telescopic support frames are used to move the workbench 2 along the Z-axis direction, the multiple movable adjustment frames are used to move the workbench 2 along the X-axis or Y-axis direction, and the push rod assembly is used to move the driving shaft or the driven shaft along the X-axis direction.

[0019] The stirring shaft is first installed and fixed along the X-axis direction, and one end of the stirring shaft is heated; then the driving shaft or the driven shaft is supported along the X-axis direction by a slide, and a plurality of telescopic support frames are adjusted to adjust the driving shaft or the driven shaft to a suitable height, and then a plurality of movable adjustment frames are adjusted to move the workbench 2 along the X-axis or Y-axis direction, so that the driving shaft or the driven shaft moves to a position coaxial with the stirring shaft, and then the push rod assembly is used to move one end of the driving shaft or the driven shaft toward the stirring shaft, and one end of the driving shaft or the driven shaft is nested in the stirring shaft, so as to quickly and accurately position the stirring shaft and the driving shaft or the driven shaft to complete the shrink sleeve connection.

[0020] In the present invention, the connection between the workbench 2 and the slide is connected by at least one hydraulic linear guide pair 3 arranged along the X-axis direction. The hydraulic linear guide pairs 3 are arranged in parallel and spaced apart when they are greater than 1; the movement of the slide is guided by the hydraulic linear guide pairs 3. In this embodiment, there are two hydraulic linear guide pairs 3 to improve the stability of the slide during movement.

[0021] Two rows of swivel support seats are arranged along the X-axis direction on the top of the slide, and the two rows of swivel support seats are distributed on both sides of the bottom of the driving shaft or the driven shaft to provide rolling support to facilitate the movement of the driving shaft or the driven shaft; each row of swivel support seats includes a plurality of swivel support seats 4 linearly spaced along the X-axis direction. In this embodiment, there are three swivel support seats 4 in each row of swivel support seats.

[0022] like Figure 1 , Figure 3 and Figure 5 As shown, according to another embodiment of the present invention, a horizontal shrink fitting tooling, wherein the push rod assembly includes a mounting frame connected to the workbench 2 and a push rod 5 connected to one end of the driving shaft or the driven shaft, the push rod 5 is arranged along the X-axis direction and the push rod 5 is rotatably connected to the mounting frame through two length adjustment structures, the two length adjustment structures are connected through a driver 7, and the driver 7 is telescopically adjusted to make the two length adjustment structures extend or shorten synchronously.

[0023] When the driving shaft or the driven shaft moves to a position coaxial with the stirring shaft, the driver 7 provides power to make the two length adjustment structures extend synchronously, so that the push rod 5 moves in the direction close to the stirring shaft, and the push rod 5 drives the driving shaft or the driven shaft to move in the direction close to the stirring shaft until one end of the driving shaft or the driven shaft is embedded in the stirring shaft to complete the shrink fit connection; after the push rod 5 is disconnected from the driving shaft or the driven shaft, the driver 7 makes the two length adjustment structures shorten synchronously, so that the push rod 5 moves in the direction away from the stirring shaft, so as to facilitate the installation of the next driving shaft or driven shaft to perform the above work.

[0024] Each length adjustment structure specifically adopted in the present invention includes two transmission rods 6, one end of the two transmission rods 6 is rotatably connected, the unconnected end of one transmission rod 6 is rotatably connected to the top rod 5, and the unconnected end of the other transmission rod 6 is rotatably connected to the mounting frame, and the driver 7 is connected between the rotational connection points of the two transmission rods 6 in the two length adjustment structures.

[0025] In this embodiment, the driver 7 can be an electric jack, which can be telescopically adjusted to make the two transmission rods 6 in each length adjustment structure rotate toward or away from each other, so that the relative length of the two transmission rods 6 in each length adjustment structure can make the push rod 5 move along the X-axis direction; two length adjustment structures are used to make the movement process of the driving push rod 5 more stable.

[0026] The mounting frame used in the present invention includes a plurality of parallel and spaced columns 8, the lower ends of the plurality of columns 8 are fixedly connected to the workbench 2, a mounting plate 9 is connected to one side of the top end of the plurality of columns 8, one of the transmission rods 6 in the two length adjustment structures is rotatably connected to the mounting plate 9, the other transmission rod 6 in the two length adjustment structures is rotatably connected to the top rod 5 through the same connecting plate 10, and the mounting plate 9 is connected to at least one slide groove arranged along the X-axis direction, and the connecting plate 10 is slidably connected to each slide groove.

[0027] A plurality of columns 8 form a supporting framework of the two length adjustment structures. In the present embodiment, the number of the columns 8 is three. The mounting plate 9 is used to reasonably mount one of the transmission rods 6 in the two length adjustment structures. The connecting plate 10 is used to reasonably mount and connect the top rod 5 and the other transmission rod 6 in the two length adjustment structures, so that the installation of the transmission rod 6 of the two length adjustment structures is more stable and firm.

[0028] The movement of the mounting plate 9 is limited and guided by the slide groove, thereby limiting and guiding the movement between the two transmission rods 6 of each length adjustment structure, so that the movement of the two transmission rods 6 of each length adjustment structure is more stable; in this embodiment, there are two slide grooves, which are arranged in parallel and at intervals to further improve the stability of the mounting plate 9 during movement.

[0029] In the invention, a push rod positioning sleeve 11 is also connected to the end of the push rod 5 used to be connected to the driving shaft or the driven shaft. The push rod positioning sleeve 11 cooperates with the positioning groove on the driving shaft or the driven shaft to position the push rod 5, so that the push rod 5 is quickly located on the central axis of the driving shaft or the driven shaft to enable the driving shaft or the driven shaft to move stably; the connection between the push rod 5 and the driving shaft or the driven shaft is a snap-fit ​​fit between the push rod positioning sleeve 11 and the positioning groove on the driving shaft or the driven shaft.

[0030] like Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, a horizontal shrink fitting tooling is described, wherein each of the telescopic support frames includes a universal ball 12 fixedly connected to the base 1 and a lifting bracket connected to the universal ball 12, and the top of the lifting bracket is against the workbench 2.

[0031] The lifting bracket and the base plate are connected by a universal ball 12, which also serves to prevent vibration of the lifting bracket. The telescopic adjustment of the lifting bracket can quickly adjust the height of the workbench 2 to achieve the purpose of adjusting the height of the driving shaft or driven shaft arranged on the slide.

[0032] In this embodiment, the workbench 2 is a horizontally arranged rectangular parallelepiped structure, and there are four telescopic support frames, which are distributed at four angles of the workbench 2 to stably support the workbench 2 .

[0033] The lifting bracket specifically used in the present invention includes a support shaft 13 connected to a universal ball 12 and a movable cylinder 14 threadedly sleeved on the upper side of the support shaft 13, a supporting abutment block 15 for abutting against the workbench 2 is connected to the top of the movable cylinder 14, and a plurality of adjustment rods 16 are circumferentially arranged on the outer wall of the movable cylinder 14.

[0034] In this embodiment, there are four adjusting rods 16, and the four adjusting rods 16 are used to facilitate the rotation of the movable cylinder 14, so that the movable cylinder 14 moves on the support shaft 13 to adjust the height position of the support offset block 15, thereby achieving the height adjustment of the workbench 2; the support offset block 15 and the workbench 2 are connected in an offset manner, so that multiple movable adjustment frames can be used to allow the workbench 2 to move unrestricted along the X-axis or Y-axis direction.

[0036] When the mobile workbench 2 moves along the X-axis direction toward the stirring axis, the limit column 18 is slidably mounted on the guide column 17 through the clamping sleeve, and the movement of the workbench 2 along the X-axis direction is limited by the cooperation of the guide column 17, the limit column 18 and the clamping sleeve, and then the workbench 2 is limited and fixed along the X-axis direction by the cooperation of the movable adjustment frame arranged at the other end of the workbench 2.

[0037] The abutment frame formed by the cooperation of the guide column 17, the limit column 18 and the clamping sleeve enables the movable adjustment frames arranged at both ends of the workbench 2 along the X-axis direction to abut against each other in different height directions to form a more stable clamping force for the workbench 2.

[0041] In order to facilitate the rotation of the adjusting screw 20 , a handle may be fixedly inserted at the end of each adjusting screw 20 , so that the rotating process of the adjusting screw 20 is more labor-saving.

[0042] Each adjusting screw 20 is threadedly sleeved with two nuts, and the two nuts are fixedly connected to the top of the support column 19 so that the adjusting screw 20 is rotatably connected to the support column 19.

[0043] In this embodiment, the end of the driving head 21 that abuts against the workbench 2 is arc-shaped, so as to increase the abutting force between the driving head 21 and the workbench 2 to enable the workbench 2 to move quickly.

[0044] At the same time, in order to improve the structural strength of the multiple movable adjustment frames, the support columns 19 in the multiple movable adjustment frames are connected together by multiple connecting columns 22, and the projections of the multiple connecting columns 22 on the top surface of the base 1 are closed ring structures.

[0045] The annular structure in this embodiment is specifically a rectangular annular structure, which has stronger stability after connecting multiple movable adjustment frames into one.

[0046] like Figure 2As shown, according to another embodiment of the present invention, in a horizontal shrink-fit tooling, a dial indicator 24 is connected to the end of the driving shaft or the driven shaft away from the push rod assembly, that is, the end of the driving shaft or the driven shaft used to connect with the stirring shaft through a universal magnetic gauge seat 23; the universal magnetic gauge seat 23 is fixed to the end face of the driving shaft or the driven shaft by adsorption to facilitate installation or disassembly, the dial indicator 24 is against the inner circle of the tube at one end of the stirring shaft, the driven shaft or the driving shaft is rotated, the runout value of the dial indicator 24 is read, the runout of the driving shaft or the driven shaft and the stirring shaft is aligned in sections, and adjusted according to the technical requirements (the driven shaft or the driving shaft is axially aligned with the stirring shaft) until the runout is qualified, and then the driving shaft or the driven shaft is removed, the end of the stirring shaft is heated, and then the shrink-fit is performed to further improve the connection accuracy.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
