Description

Quick pin cutting machine for bearing

Technical Field

The utility model belongs to the technical field of the bearing processing, concretely relates to quick pin cutting machine is used to bearing.

Background

In the manufacturing process of the special bearing for RE, RB and RU robots, in order to finish the final assembly between bearing parts, an assembly structure process can be formed, as shown in figure 3, wherein D is a bearing outer ring body, in order to install a rolling body into the body, a mounting hole O needs to be formed on the side wall of the body, after the assembly is finished, the hole O needs to be sealed by a plug, and then a pin A is strung between the plug and the body to fix the plug and the body into a complete body; however, in the manufacturing process, the redundant pin parts B and C are inevitably generated, and after the installation is completed, the two parts need to be cut off; the conventional cutting method is shown in fig. 4, and needs a skilled operator to manually and visually cut off the redundant parts B and C, but in the actual working process, many problems are generated, for example, excessive cutting amount may damage the bearing body, insufficient cutting may damage the grinding wheel in the later grinding process, and therefore, the cutting amount control in the redundant pin cutting process is difficult.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model aims at providing a quick pin cutting machine is used to bearing.

The utility model adopts the following technical scheme for accomplishing the above purpose:

a quick pin cutter for bearings is provided with a support plate; the supporting plate is a triangular plate with an inclined upper end face, and an included angle between the upper end face and the bottom face of the supporting plate is 25 degrees; the two support plates are arranged in bilateral symmetry; the upper end surfaces of the two supporting plates are connected into a whole by a horizontal table plate to form a supporting table frame; a supporting bottom plate for supporting the cutting machine is arranged at one end of the horizontal platform plate of the supporting rack; the supporting bottom plate is supported at the higher end of the horizontal table plate through an adjusting nut and an adjusting stud; a standard block with the same thickness as the bearing to be cut is arranged between the supporting bottom plate and the horizontal table plate; a bearing to be cut is placed at the lower end of the horizontal platform plate; the end surface of one side of the supporting bottom plate, which is contacted with the bearing to be cut, is provided with a notch used for clamping the part to be cut; an upper cutter and a lower cutter are respectively fixed on the upper end surface of the supporting bottom plate and the lower end surface of the horizontal platform plate; the upper cutting machine and the lower cutting machine are symmetrically arranged.

The upper cutting machine and the lower cutting machine are grinding machines; the vertical distance between the cutting sheets of the upper cutting machine and the lower cutting machine is the same as the thickness of the body of the bearing to be cut.

The utility model provides a pair of quick pin cutting machine is used to bearing, adopt above-mentioned technical scheme, accomplish simultaneously and wait to cut the cutting when the upper and lower unnecessary part of bearing, the complete machine is 25 slope structural design, the scrap iron that produces in the cutting process falls automatically, is unlikely to cause cutting error's production and unnecessary injury to other places, has thoroughly solved cutting inefficiency, requires high to the staff of processing technique level, machining error is big, the inherent drawback of rejection rate height has improved work efficiency.
