Detailed Description

The utility model will be described in detail below with reference to the attached drawings:

examples: as shown in figures 1-6, the profiling press-fitting tool for the vulcanized bearing support comprises a device press head 1, a three-column groove shell 2, a shell part 21, a long handle part 22, a bearing support 3, a positioning hole 31, a tool body 4, a central groove 41, a profiling groove 42, a tool positioning hole 43, a support positioning pin 44, a limiting stop 45, a boss 46, a device workbench 5 and a chute 51. Referring to fig. 6, one end of the three-column housing 2 is a housing portion 21, the other end is a long handle portion 22, and before press fitting, the bearing support 3 is sleeved at the connection (not tightly connected) between the housing portion 21 and the long handle portion 22. As shown in fig. 1 and 2, the middle of the tool body 4 is provided with a central groove 41 through which the long handle portion 22 passes, and the bearing support 3 clamps the housing portion 21 on the central groove 41, and at the same time, the long handle portion 22 can move inwards along the central groove 41. Further, the upper surface of the tool body 4 at the outer edge of the central groove 41 is provided with a profiling groove 42, the shape of the profiling groove 42 is matched with that of the bearing support 3, and three tool positioning holes 43 are formed in the profiling groove 42 in a penetrating mode and are used for being matched with the equipment workbench 5 to fix the tool body 4. Two support locating pins 44 are symmetrically arranged on the imitation groove 42, locating holes 31 are formed in two sides of the support locating pins 44 (as shown in fig. 6), and when the bearing support 3 slides to the upper side of the imitation groove 42, the locating holes 31 are matched with the support locating pins 44 to locate the bearing support 3 with the tool body 4. Referring to fig. 5, after the positioning is completed, the three-column housing 2 is press-fitted with the bearing support 3 by the device ram 1.

As a preferable solution, as shown in fig. 5, a chute 51 is formed on the equipment table 5 at a position corresponding to the central slot 41, so that the long handle 22 slides.

As a preferable technical solution, as shown in fig. 1 and 2, two limit bars 45 are provided at the outer edge of the profiling groove 42, for stopping the bearing support 3, preventing the bearing support 3 from excessively sliding and shifting from above the profiling groove 42.

As a preferred embodiment, the central slot 41 includes a straight line segment distal from the contoured slot 42 and a semi-circular arc segment proximal to the contoured slot 42. Wherein, the straight line section can be used for the long handle part 22 to slide, so that the bearing support 3 gradually approaches the imitation groove 42; the semi-circular arc section serves to limit the continued sliding of the long shank 22, ensuring that the bearing support 3 moves over the profiled groove 42. Further, referring to fig. 2, a circle of boss 46 is provided at the edge of the semicircular arc section, and the height of the boss 46 is 0.2mm. The boss 46 is arranged to enable the vulcanized bearing support 3 to bear force only on the inner diameter of the bearing in the press fitting process, and the rest part is not stressed, so that stress deformation of other parts of the vulcanized bearing support 3 is avoided.

The press-fitting process of the utility model comprises the following steps: as shown in fig. 5, during press fitting, the three-column housing 2 is placed on the table surface of the equipment table 5 with the housing portion 21 facing downward and the long handle portion 22 facing upward; the bearing support 3 is sleeved at the joint of the shell part 21 and the long handle part 22, but is not tightly connected, and a plurality of three-column groove shells 2 can be placed for standby at one time according to the size of the equipment workbench 5, so that the press-fitting efficiency is improved. Then, the operator holds the long handle 22 with one hand (the first hand and the second hand are downward), puts the three-column housing 2 upside down (the housing 21 is upward and the long handle 22 is downward) on the tool body 4, makes the long handle 22 pass through the central groove 41 and the sliding groove 51, and simultaneously places the bottom of the bearing support 3 on the upper surface of the tool body 4, and pushes the long handle 22 toward the inner side of the central groove 41 by hand, so that the bearing support 3 also moves synchronously. When the bearing support 3 is pushed to the position of the limit stop bar 45 of the tooling body 4, the bearing support 3 and the three-column groove shell 2 are directly in place, and meanwhile, the support positioning pin 44 in the imitation groove 42 is also directly inserted into the positioning hole 31 of the bearing support 3. At the moment, a starting button on the equipment is pressed, and the press fitting can be completed by starting the equipment press head 1. When the continuous press fitting is performed, an operator can hold the press-fitted three-column groove shell 2 by one hand and press-fit the three-column groove shell 2 by one hand, so that simultaneous loading and unloading are realized. Compared with the original press mounting mode, the working efficiency can be improved by more than one time.
