Description

Technical Field

[0001] The utility model relates to the technical field of shaft sleeve processing, in particular to a clamping mechanism for automatic milling of shaft sleeve oil grooves. Background Art

[0002] The oil groove on the inner surface of the sleeve is mainly used to store lubricating oil and lubricate the bearing to prevent increased wear or even damage due to oil shortage. The oil groove should be opened at the sleeve roll joint to facilitate the entry of lubricating oil. Conventional processing of this oil groove usually places the sleeve on a workbench and drives the milling cutter downward to groove it. However, the milling process can easily cause uneven force on the sleeve, causing movement and displacement of the groove. Utility Model Content

[0003] The purpose of the utility model is to provide a clamping mechanism for automatic milling of a shaft sleeve oil groove, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping mechanism for automatic milling of shaft sleeve oil grooves, comprising a workbench and a milling cutter, wherein the milling cutter is arranged directly above the workbench, and further comprising a telescopic cylinder, wherein the workbench is mounted on the output end of the telescopic cylinder, and a clamping plate is connected to the piston rod of the telescopic cylinder, and the clamping plate is moved down to directly above the workbench at one end away from the telescopic cylinder, and a milling cutter opening is provided on the clamping plate, and the milling cutter opening corresponds to the slotting position of the shaft sleeve workpiece, one end of the milling cutter extends into the milling cutter opening, and a milling cutter power mounting head is connected to the other end, and the end of the milling cutter power mounting head away from the milling cutter is connected to a drive motor via a coupling, and a lifting device for driving the milling cutter to move down to open a slot is connected to the side of the milling cutter power mounting head.

[0005] The present invention incorporates the following improvements: a connecting plate is provided at the output end of the telescopic cylinder, with a support frame attached to the outside of the connecting plate. A slide rail is mounted on the side of the support frame closest to the pressure plate, and a wedge-shaped slider is provided on the slide rail, the outer end of which is connected to the pressure plate. By providing the support frame and wedge-shaped slider, the upward and downward movement of the pressure plate is limited, preventing deviation and resulting in failure of the fixation.

[0006] The following improvement is made in the solution of the present application: a through hole corresponding to the piston rod of the telescopic cylinder is opened on the connecting plate.

[0007] The following improvement is made in the solution of the present application: the pressing plate is fixed to the piston rod of the telescopic cylinder by a nut.

[0008] The following improvements are made in the present application: the workbench includes a platform, the bottoms of both sides of the platform are respectively connected to support plates, and one end of the support plate away from the platform is fixedly connected to the top of the connecting plate.

[0009] The present invention incorporates the following improvements: a channel is defined at the top of the platform, corresponding to the milling cutter opening. The channel's diameter is larger than the maximum diameter of the milling cutter's rotating profile and smaller than the diameter of the sleeve workpiece. The channel is provided on the worktable to coordinate with the milling cutter's downward rotation path, preventing the worktable from being damaged by milling during machining.

[0010] Compared with the prior art, the present invention provides a clamping mechanism for automatic milling of a shaft sleeve oil groove, which has the following beneficial effects:

[0011] The utility model fixes the shaft sleeve workpiece through the coordinated arrangement between the workbench, the telescopic cylinder and the pressing plate, thereby preventing the shaft sleeve from moving and causing the slot position to shift due to uneven force during grooving, and further improving the milling accuracy. The telescopic cylinder drives the pressing plate to press the shaft sleeve workpiece downward, and under the coordinated drive of the driving motor and the lifting device, the milling cutter rotates and moves downward to perform grooving.
