[0022] Example 1

[0023] like Figure 1 、 Figure 2 and Figure 3 As shown, Figure 1 A three-dimensional view of the connection structure between the clamping plate and the clamping disc; Figure 2 is a connection view of the jack; Figure 3 This is a schematic diagram of the use status of the aluminum alloy cast roller bearing box safety disassembly device.

[0024] The aluminum alloy casting roller bearing box safety disassembly device of the utility model includes a connecting rod, a clamping plate 7, a chuck 8 and a jack 9, the two ends of the connecting rod are respectively connected to the clamping plate 7 and the chuck 8, the clamping plate 7 is provided with a clamping groove 15, the casting roller 10 is arranged in the clamping groove 15, the bearing box plate 11 is arranged between the clamping plate 7 and the chuck 8, the jack 9 is arranged between the bearing box plate 11 and the chuck 8, and one end of the jack 9 is arranged in contact with the end of the casting roller 10 and the other end is arranged in contact with the chuck 8. The jack 9 presses the end of the casting roller 10 and the chuck 8, so that the bearing box plate 11 moves toward the chuck 8 under the driving action of the clamping plate 7, thereby the casting roller 10 is disassembled and pulled out from the bearing box plate 11.

[0025] Preferably, at least two connecting rods are provided, and the two connecting rods are symmetrically arranged on both sides of the clamping groove 15, and the connecting rods are arranged in parallel.

[0026] Generally, the clamping plate 7 and the chuck 8 are arranged in parallel to ensure that the top pressure generated by the jack 9 is stably transmitted to the bearing box plate 11.

[0027] Preferably, the clamping groove 15 extends from the edge of the clamping plate 7 along the center line of the clamping plate 7 toward the center, and a top pressure groove 16 is provided at the center of the chuck 8. The cross section of the top pressure groove 16 is set to be circular, and the top pressure groove 16 is formed by the concave surface of the chuck 8 close to the clamping plate 7. The axis of the top pressure groove 16 is set perpendicular to the center line of the clamping plate 7, and the end of the jack 9 connected to the chuck 8 is set in the top pressure groove 16.

[0028] During the top pressure process, the clamping groove 15 is arranged on the casting roller 10 and will be blocked by the bearing box plate 11. By setting the top pressure groove 16, the position of the clamping groove 15 can be aligned when the jack 9 is placed to ensure that the top pressure applied by the jack 9 can be smoothly transmitted through each connecting rod. At the same time, the concave top pressure groove 16 can also ensure that the position of the end of the jack 9 on the chuck 8 is stable.

[0029] Generally, the bottom of the clamping groove 15 is set to be arc-shaped, which facilitates the fit between the bottom of the clamping groove 15 and the outer surface of the casting roller 10. Generally, the groove width of the clamping groove 15 is matched with the roller diameter of the casting roller 10.

[0030] The utility model sets the connected clamping plate 7 and the chuck 8, and presses the chuck 8 with the jack 9, so that the bearing box plate 11 is separated from the bearing box plate 11 under the driving action of the clamping plate 7. The labor intensity of personnel is low, the disassembly process is safe and reliable, and while improving work efficiency, production safety and product quality are guaranteed.

[0031] Example 2

[0032] The connecting rod is configured as a screw rod, a first connecting hole is provided on the clamping plate 7, and a second connecting hole is provided on the chuck 8. The first connecting hole and the second connecting hole are provided in a one-to-one correspondence, and the connecting rod is simultaneously provided in the corresponding first connecting hole and the second connecting hole. Both ends of each connecting rod are threadedly connected to a limiting nut, and the clamping plate 7 and the chuck 8 are provided between the two limiting nuts of the same connecting rod. The clamping plate 7 and the chuck 8 are limited by the limiting nut to realize the connection between the clamping plate 7 and the chuck 8.

[0033] Generally, a gasket 12 is provided between the clamping plate 7 or the clamping disc 8 and the corresponding limiting nut to ensure close contact between the clamping plate 7 or the clamping disc 8 and the corresponding limiting nut and effectively realize force transmission.

[0034] Specifically, the connecting rod includes a first connecting rod 3 and a second connecting rod 4, the two ends of the first connecting rod 3 are respectively threadedly connected with a first limiting nut 1 and a second limiting nut 6, the two ends of the second connecting rod 4 are respectively threadedly connected with a third limiting nut 2 and a fourth limiting nut 5, the gasket 12 is arranged between the first limiting nut 1, the third limiting nut 2 and the chuck 8, and the gasket 12 is arranged between the second limiting nut 6, the fourth limiting nut 5 and the clamping plate 7.

[0035] During disassembly, the clamping plate 7 and the chuck 8 need to be leveled by the limiting nut so that the clamping plate 7 and the chuck 8 are arranged in parallel to ensure that the top pressure generated by the jack 9 is stably transmitted to the bearing box plate 11.

[0036] Example 3

[0037] like Figure 4 As shown, Figure 4 It is a cross-sectional view of the connection structure between the clamping plate and the clamping disc in this embodiment.

[0038] This embodiment is a further improvement on the basis of the second embodiment, in that a limiting sleeve 13 is further provided between the clamping plate 7 and the chuck 8. The limiting sleeve 13 is configured as a cylindrical tubular member, and the connecting rod is disposed within the limiting sleeve 13. At least two limiting sleeves 13 are provided, and the two limiting sleeves 13 are symmetrically disposed on both sides of the clamping groove 15. The provision of the limiting sleeves 13 eliminates the need for leveling. It is only necessary to provide two symmetrical and equal-length limiting sleeves 13 and tighten the limiting nut so that the ends of the limiting sleeves 13 are in contact with and against the end surfaces of the clamping plate 7 and the chuck 8, respectively, thereby ensuring the parallelism of the clamping plate 7 and the chuck 8.

[0039] Preferably, a limiting ring 14 is fixedly provided on both the clamping plate 7 and the chuck 8, the limiting ring 14 is provided between the clamping plate 7 and the chuck 8, the limiting ring 14 and the first connecting hole or the second connecting hole are provided in a one-to-one correspondence, the limiting ring 14 is provided in a cylindrical ring shape, the limiting ring 14 and the corresponding first connecting hole or the second connecting hole are provided coaxially, and the end of the limiting sleeve 13 is sleeved on the limiting ring 14. By providing the limiting ring 14, the relative positions of the limiting sleeve 13, the clamping plate 7 and the chuck 8 can be fixed when the end of the limiting sleeve 13 contacts and abuts against the end faces of the clamping plate 7 and the chuck 8 respectively, so that the limiting sleeve 13, the clamping plate 7 and the chuck 8 form a stable overall structure, which is convenient for the transmission of force during disassembly.

[0040] Preferably, the inner diameter of the limiting ring 14 is equal to or larger than the corresponding aperture of the first connecting hole or the second connecting hole, and the outer diameter of the limiting ring 14 is slightly smaller than the inner diameter of the limiting sleeve 13. Generally, the outer diameter of the limiting ring 14 is 0.5mm to 1.2mm smaller than the inner diameter of the limiting sleeve 13, to ensure smooth installation. At the same time, the small gap also reduces the shaking between the limiting sleeve 13 and the limiting ring 14.

[0041] Since the connecting rod is generally provided with an external thread for easy threaded connection with the limiting nut, in order to facilitate the installation of the clamping plate 7 and the chuck 8, the aperture of the first connecting hole or the second connecting hole is generally set larger, so the gap is larger, which makes it easy for the connecting rod to shake between the clamping plate 7 and the chuck 8 after the connection is completed, causing the clamping plate 7 and the chuck 8 to be skewed, which is not conducive to the transmission of force. By setting the limiting sleeve 13, the parallel setting of the clamping plate 7 and the chuck 8 can be effectively guaranteed, and the setting of the limiting ring 14 can stabilize the setting state of the limiting sleeve 13.

[0042] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
