Description

Technical Field

[0001] This utility model relates to the field of bearing quick alignment and assembly technology, and in particular to bearing quick alignment and assembly tooling. Background Technology

[0002] Bearings, as core components of mechanical transmission systems, are widely used in various rotating equipment, such as machine tool spindles, automobile wheel hubs, wind turbine generators, and industrial robots. Their assembly quality directly affects the stability, load-bearing capacity, and service life of the equipment. During bearing installation, it is essential to ensure the coaxiality of the inner and outer rings, as well as the fitting accuracy between the bearing and the shaft and bearing housing, to avoid problems such as abnormal vibration, localized stress concentration, or premature failure caused by installation deviations.

[0003] In most existing devices, the fit between the bearing and the bearing rod is an interference fit. The traditional assembly method is to first cool the bearing rod in liquid nitrogen, which reduces the size of the bearing rod through thermal expansion and contraction. Then, the bearing and the bearing rod are assembled. After the bearing rod returns to room temperature, the bearing and the bearing rod achieve an interference fit, which is a tight fit. Although the above method can achieve the assembly effect, it does not take into account that the operation process is relatively cumbersome, which reduces the working efficiency of the device. At the same time, cooling the bearing rod with liquid nitrogen increases the operating cost of the device.

[0004] Therefore, a quick bearing alignment assembly fixture is proposed. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a bearing quick-alignment assembly fixture, including a base plate 1. Four sets of support legs 2 are fixedly installed at the bottom of the base plate 1 in a rectangular arrangement. Two sets of support columns 3 are fixedly installed at the top of the base plate 1, arranged horizontally. A top plate 5 is fixedly installed on the top of the support columns 3. A placement plate 4 is fixedly installed on the top of the base plate 1. A hydraulic rod 6 is fixedly installed on the top of the top plate 5. A stamping rod 7 is fixedly installed through the free end of the hydraulic rod 6 through the top plate 5. A transmission device 8 is provided on the stamping rod 7. The transmission device 8 includes a connecting block 801 fixedly installed on the stamping rod 7, and also includes an L-shaped connecting rod 802, a transmission gear block 803, an L-shaped connecting plate 804, and a transmission gear. 805, worm gear 806, first transmission wheel 807, first transmission belt 808, transmission rod 809 and worm wheel 810, threaded rod 18 and one end of transmission rod 809 pass through base plate 1 and are fixedly installed with second transmission wheel 16. Second transmission belt 17 is sleeved on second transmission wheel 16 and second transmission wheel 16 is driven by second transmission belt 17. This allows the device to drive limit block 19 to lift up while controlling hydraulic rod 6 to drive stamping block 11 to stamp bearing rod 15. The protrusion on limit block 19 is then in contact with the bottom of product body 12, thereby limiting product body 12 and preventing it from moving during assembly, thus improving the assembly effect of the device.

[0025] like Figure 3 As shown, the placement plate 4 has a groove inside, and a threaded rod 18 is rotatably installed on the bottom inner side of the groove. A limiting block 19 is threadedly installed on the threaded rod 18, and the limiting block 19 is slidably connected to the groove. A protrusion is provided on the top of the limiting block 19, which allows the operator to easily align the product body 12 with the stamping block 11, improving the assembly effect of the device. At the same time, the device can control the limiting block 19 to move upward continuously and disengage from the threaded rod 18 after the product body 12 is removed, so that the operator can replace the limiting block 19. By replacing the limiting block 19, the shape of the protrusion can be changed, so that the protrusion can better limit different product bodies 12, improving the practicality of the device.

[0026] like Figure 1 As shown, a control box 9 is fixedly installed on one side of the support column 3, and a switch lever 10 is rotatably installed on one side of the control box 9, which makes it easier for operators to control the device, optimizes the operation steps of the device, and improves the practicality of the device.

[0027] like Figure 4As shown, the top of the placement plate 4 is provided with a product body 12, and a bearing 13 is provided inside the product body 12. A C-shaped groove 14 is provided on the bearing 13, and a bearing rod 15 is provided inside the bearing 13. After the bearing rod 15 is stamped by the stamping block 11, the iron part at the top of the bearing rod 15 will extend outward under the action of the stamping and fit into the C-shaped groove 14. This allows the product body 12, bearing 13 and bearing rod 15 to be tightly combined, which simplifies the bearing assembly process, improves the working efficiency of the device and increases the practicality of the device.

[0028] like Figure 4 As shown, a stamping block 11 is fixedly installed at one end of the stamping rod 7. A resistance heating block is provided inside the stamping block 11, so that the device can heat the bearing rod 15 to a certain extent through the setting of the resistance heating block. Since the metal is more likely to deform after being heated, it can better fit with the C-shaped groove 14, thus improving the practicality of the device.

[0029] Working principle: In use, the product body 12 is aligned with the stamping block 11 by the protrusion on the limiting block 19 and placed on the placement plate 4. The bearing 13 is placed inside the product body 12, and the bearing rod 15 is placed inside the bearing 13. By pulling the switch lever 10, a signal is sent to the control box 9, and the control box 9 controls the hydraulic rod 6 to start, causing the hydraulic rod 6 to drive the stamping rod 7 to descend, which in turn drives the stamping block 11 to descend and stamp the bearing rod 15. Because the bearing rod 15 is hollow, when the bearing rod 15 is stamped by the stamping block 11, the iron will extend outward and finally press down on the C-shaped groove 14, thereby achieving precision assembly. When the stamping rod 7 is pressing down, the connecting block 801 enables the stamping rod 7 to drive the L-shaped connecting rod 802 to descend, and the transmission gear block 803 and the... The meshing of the transmission gear 805 enables the L-shaped connecting rod 802 to drive the transmission gear 805 to rotate. The transmission of the first transmission wheel 807 and the first transmission belt 808 enables the rotation of the transmission gear 805 to drive the worm 806 to rotate. The meshing of the worm 806 and the worm wheel 810 enables the worm 806 to drive the transmission rod 809 to rotate. The transmission of the second transmission wheel 16 and the second transmission belt 17 enables the transmission rod 809 to drive the threaded rod 18 to rotate, thereby enabling it to move the limiting block 19 longitudinally. The longitudinal movement of the limiting block 19 drives the protrusion on the limiting block 19 to move longitudinally and fit against the bottom of the product body 12, thereby limiting the product body 12 and preventing it from moving during assembly.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
