Description

Technical Field

[0001] The utility model relates to the technical field of bearing ring positioning, and more specifically, to a cross roller bearing ring processing and positioning component. Background Art

[0002] Crossed roller bearings are a special type of bearing with a split inner ring and a rotating outer ring. Due to their special structure, they are usually used as spherical bearings in industrial robots. They can provide high rotation accuracy and rigidity in a small space, greatly saving material costs. This type of bearing is to install two sets of bearing raceways and rollers together at right angles, with adjacent rollers facing opposite directions. The processing accuracy requirements for the bearing rings are relatively high. When used, the positioning device for ring processing in the prior art generally fixes the inner layer of the bearing first, then processes the outer layer, and then processes the inner layer after the outer layer is processed. For example, a cross roller bearing ring processing positioning assembly disclosed in the prior art announcement number (CN215588535U) first puts the ring between three limiting wheels, then opens the exhaust valve, pushes the piston rod to move, and under the action of air pressure, the first piston overcomes the elastic force of the spring to move, so that the first piston pushes the limiting wheel to move, so that the limiting wheel contacts the inner layer of the ring, and then closes the exhaust valve, so that the ring can achieve the purpose of positioning;

[0003] When the above device is in use, it is convenient to collect the debris generated by the bearing ring processing and clean it. However, when the bearing ring is clamped, due to the shape of the bearing ring and the inclined state of part of the inner end surface of the bearing ring, the operation of clamping and fixing the bearing ring is relatively inconvenient. At the same time, when the bearing ring is corrected, the stability of the bearing ring is easily affected. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a crossed roller bearing ring processing and positioning assembly. The technical problem to be solved by the utility model is: how to increase the stability and convenience of the bearing ring processing and positioning.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cross roller bearing ring processing and positioning assembly, comprising a mounting base, a connecting support rod is provided at the upper end of the mounting base, a top cover is provided at the upper end of the connecting support rod, a convex cover is provided at the middle of the upper end of the top cover, a supporting slide is provided at the upper end of the top cover on the outer side of the convex cover, and a limiting slide is provided on the outer side of the upper end of the supporting slide;

[0006] A square groove is provided on the end face of the supporting slide, an adjusting screw is provided inside the square groove, a first bevel gear is provided at one end of the adjusting screw inside the convex cover, an adjusting motor is provided in the middle of the upper end of the mounting base, and a second bevel gear is provided at the upper end of the output shaft of the adjusting motor.

[0007] In a preferred embodiment, a mounting hole is formed on the outer end surface of the mounting base, and a separation groove is formed on the inner side of the mounting hole on the end surface of the mounting base;

[0008] A positioning protrusion is arranged on one side of the upper end of the limit sliding block, and a concave adapting groove is arranged on the lower end surface of the limit sliding block.

[0009] In a preferred embodiment, the outer end surface of the adjusting screw rod is provided with a screw rod connecting block, and the adjusting screw rod is sequentially arranged through the outer end surface of the top cover and the outer end surface of the convex cover;

[0010] A bearing is provided at the connection between the adjusting screw rod and the top cover and the convex cover. The number of the mounting holes is multiple and they are arranged in a circular array outside the center point of the mounting base in the top view direction.

[0011] In a preferred embodiment, the cross section of the positioning protrusion in the main viewing direction is arranged in an inclined state, and the inner end surface of the concave adaptation groove is adapted to the outer end surface of the supporting slide.

[0012] In a preferred embodiment, the supporting slides and the limiting slide blocks are provided in plural numbers and are arranged in a circular array outside the center point in the top cover in the top view direction.

[0013] In a preferred embodiment, the first bevel gear and the second bevel gear are adapted to each other through outer end tooth meshing, and the regulating motor is electrically connected to an external control device.

[0014] Technical effects and advantages of the utility model:

[0015] When the utility model is actually used, by setting the limit slider, the positioning protrusion and the concave adapter groove in a corresponding state, the inner end surface of the bearing ring can be easily fitted together through the positioning protrusion, thereby facilitating the positioning of the bearing ring.
