Description

Technical Field

[0001] This utility model relates to the field of bearing assembly tooling technology, specifically to a cylindrical roller bearing assembly tooling. Background Technology

[0002] Cylindrical roller bearings are a type of precision bearing consisting of an outer ring, an inner ring, a cage, and cylindrical rollers. They are separable bearings with characteristics of high load capacity, low noise, and high speed, and can withstand heavy radial loads and high speeds.

[0003] Currently, in small factories, when assembling cylindrical roller bearings, each cylindrical roller needs to be manually pushed into the pockets of the cage, resulting in a high workload for operators, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a cylindrical roller bearing mounting fixture with a reasonable structure and reliable operation, which solves the problem of time-consuming and laborious manual pushing of cylindrical rollers, reduces the workload of operators, and significantly improves work efficiency.

[0005] The technical solution of this utility model is:

[0006] A cylindrical roller bearing mounting fixture includes a base plate, a base fixed to one side of the upper surface of the base plate, a feeding unit and a pushing unit connected to the base. The key technical features are: a concentric bearing is fitted around the outer periphery of the upper part of the base, and a bearing seat is connected to the concentric bearing; the upper surface of the bearing seat has a positioning groove corresponding to the part to be assembled in the middle; the feeding unit includes a guide tube fixed to the middle of the upper surface of the base and a feeding hopper at the top of the guide tube; and the pushing unit includes a support fixed to the other side of the upper surface of the base plate. The base includes a bearing seat, a force-applying shaft mounted on the bearing seat, a handle at one end of the force-applying shaft, a rocker arm at the other end of the force-applying shaft, a connecting rod hinged to the other end of the rocker arm, a push rod hinged to the other end of the connecting rod, and a pressure head connected to the other end of the push rod. The lower part of the base has a clearance opening corresponding to the pressure head. The lower part of the guide riser has a radial push passage corresponding to the positioning groove. The end of the pressure head is located to the side of the radial push passage and can pass through the radial push passage. A guide support seat corresponding to the push rod is fixed on the upper surface of the base plate.

[0007] The above-mentioned cylindrical roller bearing mounting fixture has a positioning ring fixed on the outer edge of the upper surface of the bearing housing, a positioning cylinder seat fixed on the side of the base plate at the front, a positioning cylinder fixed in the positioning cylinder seat pointing to the positioning ring, a set screw, a compression spring connected to the front end of the set screw, and a steel ball connected to the front end of the compression spring fixed in the positioning cylinder, and the outer circumferential surface of the positioning ring is provided with multiple positioning pits that cooperate with the steel ball.

[0008] The aforementioned cylindrical roller bearing mounting fixture has a ratchet fixed to the outer edge of the lower surface of the bearing housing. A lever is rotatably connected to the upper surface of the base plate. One end of the lever is a round head that is in contact with the rear vertical wall of the pressure head, and the other end is hinged to the middle of the pawl push rod. The lower end of the round head is provided with a rotating shaft that inserts into the base plate. The upper edge of the base plate is provided with front guide seats corresponding to the front of the pawl push rod and rear guide seats corresponding to the rear of the pawl push rod. The front end of the pawl push rod is provided with a pawl that cooperates with the ratchet and a clamping spring to prevent the pawl from reversing.

[0009] The cylindrical roller bearing mounting fixture described above has a guide support seat with a linear guide groove corresponding to the push rod, and a limiting screw corresponding to the pressure head is provided below the linear guide groove to limit the pressure head from retracting to the cut-off position.

[0010] The aforementioned cylindrical roller bearing mounting fixture has a U-shaped pressure head. One of the two top ends of the pressure head is connected to the front end of the push rod, and the other top end is provided with a horizontal push head. The horizontal push head points to the radial push port of the guide riser, and the lower part of the pressure head passes through the clearance opening of the base.

[0011] The cylindrical roller bearing mounting fixture described above has a corresponding concentric bearing limiting mandrel fixed on the upper surface of the base, and the limiting mandrel has a limiting shoulder at the upper end of the corresponding concentric bearing.

[0012] The cylindrical roller bearing mounting fixture described above has an adjusting seat plate fixed to the edge of the base plate, which corresponds to the support shaft seat. The adjusting seat plate is provided with a horizontal screw that abuts against the support shaft seat. The support shaft seat has a long adjusting hole at the bottom, and the tip of the clamping screw passes through the long adjusting hole and is connected and fixed to the base plate.

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

[0014] 1. In use, place the outer ring of the bearing to be assembled and the retainer in the annular groove of the bearing housing. The cylindrical rollers are fed into the radial push port of the guide tube. Turn the handle to drive the swing arm to swing. The swing arm pushes the pressure head forward through the connecting rod and push rod. The pressure head pushes the cylindrical rollers into the pocket of the retainer. This replaces the manual operation method, solves the problem of time-consuming and laborious manual pushing of cylindrical rollers, reduces the workload of operators, and significantly improves work efficiency.

[0015] 2. After the top push of a cylindrical roller is completed, during the return stroke of the pressure head, the lever swings to a set angle. Through the pawl push rod and pawl, the ratchet and bearing seat are pushed to rotate, thereby causing the outer ring and retainer of the bearing to be assembled to rotate to a set angle. This causes the other empty pocket to rotate to be opposite to the radial push port of the guide tube, realizing the preparatory linkage work for the next roller loading operation, and further improving work efficiency.

[0016] 3. Before the pressure head pushes, the positioning ring and steel ball are used to achieve pre-positioning, so as to prevent the bearing seat from rotating during the push and ensure working stability. Attached Figure Description
