Description

Technical Field

[0001] This utility model belongs to the field of shaft surface processing technology, and in particular relates to a burnishing machine for processing stepped shaft surfaces. Background Technology

[0002] A polishing machine is a common piece of equipment used for surface polishing and grinding, primarily for processing materials such as metals, plastics, and ceramics. It achieves surface polishing and grinding through rotating drums and friction. The drive unit transmits the rotational motion generated by the electric motor to the drums and controls their speed and direction. Common drive units include belt drives and gear drives. Cooling system: A significant amount of heat is generated during the polishing process. To maintain the temperature of the workpiece and the drums within a suitable range, a cooling system is typically required. The cooling system can be water-cooled or air-cooled.

[0003] Roller burnishing is a plastic processing method that improves surface roughness by rolling a high-hardness, smooth roller into contact with a metal surface, causing localized micro-plastic deformation of the surface layer.

[0004] Existing calendering machines have limited processing accuracy: their processing accuracy is generally low and cannot meet some special requirements. For high-precision processing needs, other more precise processing equipment is required. Summary of the Invention

[0005] The purpose of this invention is to provide a tumbling machine that uses a motor to drive the rolling sleeve to rotate, which in turn drives the three balls to rotate, thereby achieving mechanical extrusion tumbling of the outer surface of the shaft to be processed. The surface of the shaft to be processed can obtain a high degree of smoothness, specifically Ra0.05um-0.1um, thus solving the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a calendering machine, comprising a calendering core assembly, which includes a calendering sleeve, balls, a driven wheel, and a clamping part. The driven wheel is sleeved on the outside of the calendering sleeve, and the inner surface of the calendering sleeve has a conical hole. The balls are conical cylinders concentric with the conical hole. The clamping part includes a guide rod, with a retainer for clamping the balls at one end and a coupling at the other end. A plurality of balls are embedded inside the calendering sleeve through the retainer. A bearing and a spring are sequentially arranged between the driven wheel and the coupling.

[0008] Furthermore, the driven wheel is driven by a motor via a belt.

[0009] Furthermore, the coupling is connected to a telescopic motor.

[0010] Furthermore, the outer surface of the rolling sleeve is a conical surface, and the inner surface of the driven wheel is in contact with the outer surface of the rolling sleeve.

[0011] Furthermore, the driven wheel is also provided with a rim and a through threaded hole along the radial direction of the driven wheel.

[0012] Furthermore, the retainer consists of three jaws, with a ball placed between two adjacent jaws. The retainer is located inside the conical hole of the rolling sleeve, and the three balls are used to clamp the shaft to be processed.

[0013] Furthermore, the spring is sleeved on the guide rod and located between the bearing and the coupling.

[0014] Furthermore, the bearing is a thrust bearing or a surface bearing.

[0015] Furthermore, it also includes a first cabinet and a second cabinet, with the second cabinet placed on the first cabinet; the rolled core assembly is fixed on the second cabinet, and a protective cover is provided on the second cabinet, the protective cover being located around the rolled core assembly; a cabinet door is provided on one side of the second cabinet.

[0016] Furthermore, a cooling fan is installed on the cabinet door.

[0017] This utility model has the following beneficial effects:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0027] like Figure 1 As shown, this embodiment is a calendering machine, including a calendering core assembly 5, a first cabinet 1 and a second cabinet 2, with the second cabinet 2 placed on the first cabinet 1; the calendering core assembly 5 is fixed on the second cabinet 2, and a protective cover 4 is provided on the second cabinet 2, with the protective cover 4 located around the calendering core assembly 5; a cabinet door 3 is provided on one side of the second cabinet 2, and a cooling fan 301 is provided on the cabinet door 3 to dissipate heat from the inside of the second cabinet 2.

[0028] A surrounding panel is also provided on the top perimeter of the first cabinet 1. A conduit is fixed on the top of the protective cover 4. A filter funnel is provided below the protective cover 4. A polishing slurry supply system is also provided inside the first cabinet 1. The polishing slurry supply system flows into the working section of the shaft 6 to be processed through the conduit. Then the polishing slurry enters the top surrounding panel of the first cabinet 1 through the filter funnel and then flows back into the polishing slurry tank.

[0029] A control panel is also installed on the second cabinet 2 to control the power supply, motor, start and stop, etc.

[0030] like Figure 2 As shown, the rolling core assembly 5 includes a rolling sleeve 501, a ball 502, a driven wheel 503, and a clamping part. The driven wheel 503 is sleeved on the outside of the rolling sleeve 501, and a conical hole 511 is located on the inner surface of the rolling sleeve 501. The ball 502 is a conical cylinder concentric with the conical hole 511. An annular groove is opened at one end of the ball 502.

[0031] The clamping part includes a guide rod, and a retainer 507 for clamping the ball 502 is provided at one end of the guide rod. A protrusion for engaging one end of the ball 502 in the groove is provided on the retainer 507 to limit the position of the ball 502. A coupling 505 is provided at the other end of the guide rod. Three balls 502 are embedded into the rolling sleeve 501 through the retainer 507. A bearing 506 and a spring 504 are arranged sequentially between the driven wheel 503 and the coupling 505. The bearing 506 is a thrust bearing or a plane bearing. The spring 504 is sleeved on the guide rod and located between the bearing 506 and the coupling 505.

[0032] The outer surface of the rolling sleeve 501 is a conical surface 512, and the inner surface of the driven wheel 503 is in contact with the outer surface of the rolling sleeve 501. The driven wheel 503 is driven by a motor via a belt, which drives the rolling sleeve 501 to rotate. The rotation of the rolling sleeve 501 drives the rotation of three balls 502. The rotation of the balls 502 achieves mechanical extrusion and burnishing of the outer surface of the shaft 6 to be processed, and the surface of the shaft 6 to be processed can obtain a high degree of smoothness, specifically Ra0.05um-0.1um.

[0033] The coupling 505 is connected to a telescopic motor, which realizes the reciprocating movement of the clamping part. When the shaft to be processed 6 needs to be put in or taken out, the clamping part needs to be moved backward. Since the inner surface of the rolling sleeve 501 is a conical hole 511, the three balls 502 will expand outward to facilitate the insertion or removal of the shaft to be processed 6.

[0034] The driven wheel 503 is also provided with a rim 532 and a through threaded hole 531 along the radial direction of the driven wheel 503. The screw is engaged with the threaded hole 531 to abut against the rolling sleeve 501 to form an integral unit.

[0035] like Figure 3 and Figure 4 As shown, the retainer 507 consists of three jaws, with a ball 502 placed between two adjacent jaws. The retainer 507 is located inside the conical hole 511 of the rolling sleeve 501, and the middle of the three balls 502 is used to clamp the shaft 6 to be processed.
