Description

Technical Field

[0001] This utility model belongs to the field of machining clamping technology, specifically relating to a bearing housing machining clamping device. Background Technology

[0002] With the increasing market demand for large generators, the need for machining integrated bearing housings, a necessary component within these generators, is extremely urgent. The structure of an integrated bearing housing is as follows: Figure 14 The diagram shows a cylindrical section a and fins b located on both sides of the cylindrical section a. The machined surfaces c and d of the cylindrical section and fins are not perpendicular. When boring and milling the cylindrical section surface c, it is necessary to ensure it is horizontal, while the fin surface d is necessary to ensure it is vertical. Currently, for the machining of integrated bearing housings, the bearing housing is typically first fixed on a first machine tool using a first fixture, keeping the cylindrical section surface c horizontal during machining. Then, the bearing housing with the machined cylindrical section surface c is removed from the first fixture and transferred to a second machine tool, where it is fixed using a second fixture, keeping the fin surface d vertical. Finally, the fin surface d is machined. In other words, the current conventional method for machining bearing housings involves changing fixtures and using a two-stage machining process for the cylindrical section a and fins b. This two-stage machining process has a long processing cycle and large alignment errors, significantly impacting the actual yield.

[0003] Based on the above problems, this application proposes a bearing housing machining clamping device, which can realize the horizontal adjustment of the cylindrical part machining surface c and the vertical adjustment of the fin machining surface d through a single clamping, eliminating the need for disassembly of the bearing housing and replacement of clamping fixtures, thereby reducing the defects of long processing cycle and large alignment error of the existing machining method.

[0055] The positioning adjustment mechanism 2 includes a circumferential positioning mechanism 21 for positioning the two fins b and a radial positioning mechanism 22 for positioning the inner side of the cylindrical part a. The circumferential positioning mechanism 21 is disposed on the side of the support base 12 to achieve circumferential positioning of the bearing seat and prevent the bearing seat from rotating during processing. The radial positioning mechanism 22 is disposed on the top surface of the support base 12 to achieve positioning of the inner side of the bearing seat and prevent the central axis of the bearing seat from shifting during processing.

[0056] The locking mechanism 3 is located on the side of the base 11 away from the hinge end, and is used to press and fix the support seat 12 after the angle adjustment is completed.

[0057] The suction mechanism 4 is disposed on the top surface of the support base 12. The suction mechanism 4 includes a plurality of magnetic blocks 41 for suctioning the bottom surface of the bearing seat.

The fit between the hinge shaft 14 and the hinge bushing 131 is achieved with zero clearance through lamination, which can well ensure the accuracy of use. The hinge bushing 131 and the hinge support block 13 are interference fit, which makes up for the shortcoming of the inner hole of the hinge support block 13 being not wear-resistant and increases the service life. A retaining ring 141 is provided at the end of the hinge shaft 14 to prevent it from falling out.

[0059] Preferred, such as Figure 3 As shown, the lifting assembly includes a mechanical jack 15, the bottom end of which is hinged to the base 11, and the lifting end of which is hinged to the support seat 12.

[0060] Specifically, such as Figure 4 , Figure 5 As shown, a rotating shaft plate 151 is fixedly installed on the base 11, and a rotating shaft 152 is fixedly installed on the upper part of the rotating shaft plate 151. A rotating plate 153 is fixedly installed at the bottom of the mechanical jack 15. The bottom end of the rotating plate 153 has an arc surface structure to ensure that no interference occurs during rotation. A rotating limiting groove 154 adapted to the rotating shaft 152 is provided at the bottom end of the rotating plate 153, so that the mechanical jack 15 can only swing around the rotating shaft 152 and cannot move in other directions. Locking pieces 155 are fixedly installed at both ends of the rotating plate 153 along the axial direction of the rotating shaft 152, and the locking pieces 155 are fitted tightly around the rotating shaft 152.

[0061] Specifically, the lifting end of the mechanical jack 15 is equipped with a universal ball head 156, and the support base 12 is equipped with a ball cup 157 that cooperates with the universal ball head 156. The bottom end of the ball cup 157 is equipped with a ball head baffle 158 to prevent the universal ball head 156 from slipping out of the ball cup 157.

[0062] Among them, the drive end of the mechanical jack 15 is connected to the servo motor reducer unit. The servo motor provides power input and accurately controls the lifting and lowering of the jack through the encoder, accurately controlling the angle change, so as to achieve the function of arbitrary angle adjustment.

[0063] An angle limit block 16 is provided on the base 11. The angle limit block 16 limits the extreme adjustment position when adjusting the angle. Its main function is to protect the mechanical jack 15 from disengagement during the lifting process and ensure the service life of the jack.

[0064] Preferred, such as Figure 6 As shown, the circumferential positioning mechanism 21 includes two symmetrically arranged circumferential positioning members, which are disposed between the hinge end of the support base 12 and the locking mechanism 3.

[0065] The circumferential positioning component includes a mounting plate 211 fixedly disposed on the side of the support base 12, and a support plate 212 is detachably connected to the mounting plate 211. An adjusting screw 213 for pressing the corresponding wing b is threaded onto the support plate 212.

[0066] The adjusting screws 213 in the two circumferential positioning components press the two side fins b respectively to achieve circumferential positioning of the bearing seat.

[0067] The clamping end of the adjusting screw 213 faces the direction of the locking mechanism 3.

[0068] Preferably, a locking nut 214 is threadedly fitted on the adjusting screw 213 between the pressing end of the adjusting screw 213 and the support plate 212 to prevent the adjusting screw 213 from slipping off the support plate 212 when pressing the fin b.

[0069] Preferred, such as Figure 7 As shown, a universal protective cap 215 is provided on the clamping end of the adjusting screw 213, which can effectively fit the contact surface of the fin b and play a role in protecting the surface of the product.

[0070] Preferably, the radial positioning mechanism 22 includes a plurality of positioning plates 221 evenly arranged along the circumferential direction, wherein the radial outer end of the positioning plate 221 is an arc surface structure adapted to the inner hole wall surface of the bearing seat, and the positioning plate 221 is detachably connected to the top surface of the support seat 12.

[0071] like Figure 3 As shown, a plurality of positioning plate mounting portions 121 are evenly arranged along the circumferential direction on the top surface of the support base 12. A plurality of sets of first connecting holes 122 for fixing the corresponding positioning plates 221 are arranged along the radial direction on the positioning plate mounting portions 121, wherein each set is provided with two first connecting holes 122.

[0072] like Figure 8 , Figure 9 As shown, the positioning plate 221 is provided with a second connecting hole 222. After the second connecting hole 222 on the positioning plate 221 is aligned with the corresponding first connecting hole 122, it is positioned by a positioning pin 223 and fixed by a locking screw 224.

[0073] This application enables the clamping and fixing of bearing seats with different inner diameters by setting several sets of first connecting holes 122, thereby increasing the applicability of the clamping device.

[0074] Preferably, an elastic protective block 225 is fixedly provided on the top surface of the positioning plate 221, wherein the radial outer end of the elastic protective block 225 is an arc surface structure adapted to the inner wall surface of the bearing seat. The elastic protective block 225, the positioning plate 221, and the support seat 12 are positioned by a positioning pin 223 and fixed by a locking screw 224.

[0075] Preferably, two locking mechanisms 3 are provided and symmetrically arranged, with the two locking mechanisms 3 distributed on both sides of the lifting assembly; the locking mechanism 3 includes a cylinder seat 31 fixedly mounted on the base 11, a rotary lifting cylinder 32 located on the cylinder seat 31, a pressure plate 33 connected to the top of the piston rod of the rotary lifting cylinder 32, and a lifting support rod 34 connected to one side of the bottom end of the pressure plate 33.

[0076] The support base 12 is provided with a clamping support plate 17 that is adapted to the pressure plate 33.

[0077] The pressure plate 33 has two states: a fully raised, relaxed state, and a lowered, pressed state. When the angle adjustment mechanism 1 needs to adjust the angle, the rotary lifting cylinder 32 controls the pressure plate 33 to rise and relax, so as to adjust the angle. Figure 10 , Figure 11 As shown; after the angle adjustment is completed, the rotary lifting cylinder 32 will rotate in the opposite direction and drive the pressure plate 33 to descend. The pressure plate 33 will press and lock the support plate 17, as shown. Figure 12 , Figure 13 As shown, it plays a role in enhancing the rigidity of the entire system. When the pressure plate 33 presses the support plate 17, the bottom end of the lifting support rod 34 is supported on the cylinder seat 31, which plays a role in supporting the pressure plate 33. The lifting support rod 34 can adjust the support height according to actual use needs to ensure the normal support force of the pressure plate 33.

[0078] Preferably, a plurality of magnetic blocks 41 of the suction mechanism 4 are evenly arranged on the top surface of the support base 12 along the circumferential direction, and the magnetic blocks 41 are detachably connected to the top surface of the support base 12; wherein the magnetic blocks 41 and the positioning plate 221 are arranged alternately.

[0079] The top surface of the support base 12 is provided with a plurality of magnetic block mounting grooves 123 evenly arranged in the circumferential direction, and the bottom surface of the magnetic block mounting grooves 123 is provided with a plurality of third connecting holes 124 for fixing the corresponding magnetic blocks 41 in the radial direction.

[0080] The magnetic block 41 is provided with a fourth connecting hole 42. After the fourth connecting hole 42 on the magnetic block 41 is aligned with the corresponding third connecting hole 124, it is fixed by fixing screw 43.

[0081] During use, adjust the position of the magnetic block 41 in advance according to the actual contact position between the product and the clamping device to ensure the maximum contact area between the product and the magnetic block 41, thereby obtaining the maximum magnetic clamping effect. The clamping force of the magnetic block 41 is greater than the clamping force of a normal pressure plate on the product. Its convenience is unmatched by ordinary pressure plates or even hydraulic pressure plates. The magnetic attraction of the magnetic block 41 is fast, can be replaced if damaged, and is low in cost. Hydraulic pressure plates occupy space, are prone to interference, require a hydraulic station, and are prone to pressure drop and failure; ordinary pressure plates are time-consuming and labor-intensive to operate, and occupy a large space. The magnetic block 41 uses permanent magnet technology, which is magnetized and demagnetized by electricity, making it convenient to use, and permanent magnets eliminate concerns about attraction failure.

[0082] The specific implementation method of this bearing housing machining clamping device is as follows:

[0083] like Figure 14 As shown, based on the size of the cylindrical part a in the bearing housing, the position of the magnetic block 41 is adjusted in advance to ensure the maximum contact area between the product and the magnetic block 41, thereby obtaining the maximum magnetic attraction effect. Then, the bearing housing to be processed is placed on the top surface of the support base 12. First, the positions of each positioning plate 221 are adjusted so that the radial outer side of the positioning plate 221 is tensioned on the inner side of the bearing housing to achieve radial positioning. Then, the two adjusting screws 213 are adjusted so that the adjusting screws 213 press the two side fins b respectively to achieve circumferential positioning of the bearing housing. Then, the bearing housing is attracted by the magnetic block 41. Then, the level of the cylindrical part processing surface c is adjusted by the lifting assembly. After the adjustment is completed, the rotating lifting cylinder 32 rotates in the opposite direction and drives the pressure plate 33 to descend. The pressure plate 33 presses and locks the support plate 17. Then, the processing of the cylindrical part processing surface c is carried out. After the cylindrical section machining surface c is completed, the pressure plate 33 is adjusted to the raised, released state. Then, one end of the support base 12 is raised by the lifting assembly until the fin machining surface d is in a vertical state. Afterward, the rotating lifting cylinder 32 rotates in the opposite direction and drives the pressure plate 33 to descend. The pressure plate 33 presses and locks the support plate 17, and then the fin machining surface d is machined. Therefore, the bearing housing machining clamping device of this application can achieve horizontal adjustment of the cylindrical section machining surface c and vertical adjustment of the fin machining surface d with one clamping, eliminating the need for disassembly of the bearing housing and replacement of clamping fixtures, thereby reducing the defects of long processing cycle and large alignment error of the existing machining method.

[0084] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, they are not intended to limit the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the protection scope of the present utility model.
