Description

Technical Field

[0001] The utility model belongs to the technical field of bearing bush broaching machines, in particular to a clamping device for a bearing bush broaching machine. Background Art

[0002] The bearing shell is the contact part between the sliding bearing and the journal. It is a semi-cylindrical surface in the shape of a tile and is very smooth. It is generally made of wear-resistant materials such as bronze and anti-friction alloy. In special cases, it can be made of wood, engineering plastics or rubber. There are two types of bearing shells: integral and split. Integral bearing shells are usually called bushings. Integral bearing shells are available with or without oil grooves.

[0003] A bearing broaching machine clamping device according to the formula (publication number: CN 103506689A): it includes a bearing, which is clamped on the inner tire membrane by an elastic clamping block, and the elastic clamping block is connected to the split support with screws. The split support is sequentially provided with an intermediate support, a base, and a piston fixing block four-level support, which are fixed and clamped on the piston rod in the vertical and horizontal directions with screws. The base, intermediate support and split support are respectively provided with cylindrical positioning bosses on the top, and steel ball spring plungers are inlaid on the four corners. The bottom surface of the elastic clamping block has a V-shaped surface with a gap, which is linearly matched with the cylindrical positioning boss on the split support. The middle position of the intermediate support of the base and the cylindrical positioning boss on the split support are connected with positioning screws. The outer tire membrane is positioned on the broaching machine beam by a key and fastened with four screws.

[0004] In the above application, due to the mutual cooperation between the inner tube and the split support assembly, it is difficult to solve the cooling function of the bearing clamping device during processing, resulting in the heat generated during the bearing processing causing damage to the bearing. Therefore, we proposed a bearing broaching machine clamping device. Utility Model Content

[0005] The purpose of the utility model is to provide a clamping device for a bearing broaching machine. Through the mutual cooperation between the rack, gear and water tank components of the cooling mechanism, the operator first pulls out the plug to open the water inlet, then adds cutting fluid to the inside of the water tank through the water inlet, and then starts the electric telescopic rod to make the cutting fluid inside the water tank flow from the inside of the water tank into the inside of the water pipe through the extrusion force, so as to cool the working area of the bearing. The used cutting fluid slides to the inside of the collection box through the inclined surface inside the inclined groove. This design achieves the effect of cooling the bearing processing area, effectively preventing the bearing from being damaged when the temperature is too high when the pull rod is processing the bearing, and solves the existing problem.

A water inlet is provided on the side of the water tank, and a plug is slidably connected to the inside of the water inlet.

A slanted groove 514 is provided on the top of the workbench 1, and a collecting box 515 is fixedly connected to the side of the workbench 1.

[0034] The side surface of the rack 52 is meshed with the circumferential surface of the gear 55, and one end of the moving rod 510 is located on the displacement trajectory of the knocking rod 56. The role of the mutual meshing of the side surface of the rack 52 and the circumferential surface of the gear 55 is to ensure that the movement of the rack 52 can drive the gear 55 to rotate, and the role of one end of the moving rod 510 being located on the displacement trajectory of the knocking rod 56 is to ensure that the knocking rod 56 can push the moving rod 510 during the rotation process.

[0035] A specific application of this embodiment is: when a broaching machine is needed to process a bearing, the operator first replaces the fixing clamp 48 to a suitable size by fixing the stud 410 according to the size of the bearing to be processed, and then places the bearing on top of the support clamp 46. At this time, the support clamp 46 moves downward under the influence of the gravity of the bearing, and the downward movement of the support clamp 46 drives the force rod 45 of the hydraulic cylinder 44 to move downward. At this time, the hydraulic rod 47 of the hydraulic cylinder 44 is extended outward by the pressure of the liquid inside the hydraulic cylinder 44, and the hydraulic rod 47 moves downward. The outward extension drives the clamping clamp 48 to move, and the bearing is clamped during the movement of the clamping clamp 48. After the bearing is clamped, the electric telescopic rod 41 is started, and the telescopic end of the electric telescopic rod 41 moves from right to left. The telescopic end of the electric telescopic rod 41 moves from right to left and drives the pull rod 43 to move from right to left inside the working groove 3 through the support rod 42. The bearing is processed during the movement of the pull rod 43. When the bearing processing is completed, the support clamp 46 is reset by the elasticity of the first reset spring 49, and the bearing is released.

[0036] In order to prevent the bearing from being damaged due to excessive temperature when the pull rod 43 is processing the bearing, the operator first pulls out the plug 513 to open the water injection port 512, then adds cutting fluid to the inside of the water tank 57 through the water injection port 512, and then starts the electric telescopic rod 41. The telescopic end of the electric telescopic rod 41 moves from right to left. The telescopic end of the electric telescopic rod 41 moves from right to left and drives the rack 52 to move from right to left through the connecting rod 51. Because the rack 52 and the gear 55 are engaged with each other, the rack 52 moves from right to left and drives the gear 55 to rotate counterclockwise. The gear 55 rotates counterclockwise, driving the knocking rod 56 to rotate counterclockwise. During the counterclockwise rotation of the knocking rod 56, the moving rod 510 is knocked. The moving rod 510 is pushed from right to left by the knocking rod 56. The movement of the moving rod 510 from right to left drives the extrusion plate 59 to move from right to left inside the water tank 57. At this time, the cutting fluid inside the water tank 57 flows from the inside of the water tank 57 into the inside of the water pipe 58 through the extrusion force, cooling the working area of the bearing. The used cutting fluid slides into the inside of the collection box 515 through the inclined surface inside the chute 514.
