Description

Technical Field

[0001] The utility model relates to the technical field of bearing assembly tooling, in particular to a point-to-point continuous bearing roller assembly tooling. Background Art

[0002] At present, the roller fixture of the bearing is generally composed of a roller warehouse, a dividing mold, and a stripping mold connected in sequence from top to bottom. The dividing mold and the stripping mold are respectively annular and have multiple feeding channels evenly arranged along the center line. Each roller of the bearing falls into the bearing support frame through the respective feeding channels in the roller warehouse, the dividing mold, and the stripping mold. This structural form has the following problems: if the angles of two adjacent feeding channels are equal and constant, it means that one fixture is only suitable for bearings of one size type, with a narrow application range and high cost of use.

[0006] In the above-mentioned point-to-point continuous bearing roller installation tooling, the outer peripheral surface of the lower end of the discharge pipe column is a conical surface to avoid interference with the bearing support frame when installing the roller.

[0007] In the above-mentioned point-to-point continuous bearing roller mounting tooling, the lower end of the longitudinal discharge hole is a tapered reduction opening to facilitate cutting off the discharge.

[0008] In the above-mentioned point-to-point continuous bearing roller fixture, the center line of the horizontal cylinder is parallel to the radial direction of the discharge pipe column, and the side wall of the discharge pipe column is provided with a radial through hole for the cylinder rod of the horizontal cylinder to pass through.

[0013] The beneficial effects of the utility model are:

[0014] 1. The horizontal cantilever is driven to rotate through the connecting shaft, thereby driving the discharge pipe column to rotate synchronously. During the stepping rotation process, the rollers in the discharge pipe column fall down in turn and point-to-point on the various installation points of the bearing support frame until the roller installation operation of a bearing is completed. Since the horizontal cantilever is provided with a long adjustment hole, the roller receiving seat can adjust the discharge radius by changing the relative arrangement with the long adjustment hole, so it can be applied to bearings of various sizes and types, which is flexible to use and greatly reduces the cost of use.

[0015] 2. After completing the roller installation operation of one bearing, the cylinder rod of the horizontal cylinder extends outward, and the movable blocking strip is used to press the roller to be lowered until another bearing support frame is switched into place for roller installation.

[0018] The utility model is described in detail according to the accompanying drawings of the specification.

[0019] like Figure 1As shown, the point-to-point continuous bearing roller fixture comprises an annular support plate 1 and a bracket 2 arranged on the annular support plate 1. The bracket 2 supports a connecting shaft 4 at the center by means of a bearing 3. The lower end of the connecting shaft 4 is located below the annular support plate 1 and is connected to a horizontal cantilever 6. The horizontal cantilever 6 is provided with an elongated adjustment hole 9 extending along its length direction. A roller receiving seat 5 is supported above the elongated adjustment hole 9. A receiving port is provided at the center of the roller receiving seat 5. The upper end of the discharge pipe column 10 is connected and fixed to the roller receiving seat 5 through the elongated adjustment hole 9. A longitudinal discharge hole communicating with the receiving port is provided at the center of the discharge pipe column 10. A movable material stopper strip 8 is provided on one side of the longitudinal discharge hole. A horizontal cylinder 7 is fixed to the end of the horizontal cantilever 6. The end of the cylinder rod of the horizontal cylinder 7 passes through the side wall of the discharge pipe column 10 and is connected and fixed to the movable material stopper strip 8.

[0020] In this embodiment, the bearing 3 is a tapered bearing. The upper end of the connecting shaft 4 is provided with an expansion limit section supported on the bearing 3, the lower end of the connecting shaft is provided with a stud, and the fixed end of the horizontal cantilever 6 is provided with a screw hole connected to the stud. The outer peripheral surface of the lower end of the discharge pipe column 10 is a conical surface to avoid interference with the bearing support frame when installing the roller. The lower end of the longitudinal discharge hole is a conical reduction port to facilitate cutting off the discharge. The movable material blocking strip 8 is arranged axially along the longitudinal discharge hole, and its upper and lower ends are flush with the upper and lower ends of the longitudinal discharge hole. The lower surface of the roller receiving seat 5 is provided with a threaded hole coaxial with its receiving port, and the upper end of the discharge pipe column 10 is provided with an external thread connected to the threaded hole. The center line of the horizontal cylinder 7 is parallel to the radial direction of the discharge pipe column 10, and the side wall of the discharge pipe column 10 is provided with a radial through hole for the cylinder rod of the horizontal cylinder 7 to pass through.

[0021] Working principle:

[0022] When in use, the annular support plate 1 is suspended just above the platform where the bearing support frame is located, the axis line of the connecting shaft 4 coincides with the axis line of the bearing support frame, and the position of the roller receiving seat 5 on the horizontal cantilever 6 is adjusted so that the lower end of the discharge pipe column 10 corresponds to a roller installation point of the bearing support frame.

[0023] The connecting shaft 4 is driven to rotate step by step, so that the rollers in the discharge pipe column 10 fall one by one and land point by point on the various installation points of the bearing support frame. The connecting shaft rotates 360 degrees to complete the roller installation operation of one bearing. The horizontal cylinder 7 is started to push the movable material blocking bar 8 to press the roller to be lowered to prevent it from falling further.

[0024] When the next bearing support frame switches to the roller installation position, the connecting shaft 4 rotates again, the horizontal cylinder 7 resets, the movable material blocking bar 8 releases the roller, and the rollers fall one by one again and fall point by point on each installation point of the bearing support frame to complete the roller installation operation.

[0025] The above is a detailed description of the embodiments of the utility model, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the invention of the utility model should still fall within the scope of this patent.
