Description

Technical Field

[0001] The invention belongs to the field of ultra-precision machining, and in particular relates to a continuous cylindrical roller force rheological polishing device and method. Background Art

[0002] High-end roller bearings are the core basic parts of national defense and civilian high-end equipment. They have the characteristics of high precision, high reliability, and tolerance to high-speed and heavy-load conditions. High-performance rolling bearings are mainly composed of inner and outer rings, cages and rolling elements. The raceways and cages of the inner and outer rings belong to the groove surface, and the surface of the rolling element belongs to the spherical surface or arc surface. With the development of science and technology, the service requirements for the stability and reliability of bearings are getting higher and higher. Common failure forms of bearings include wear and plastic deformation, which are mainly caused by high surface roughness of parts and low shape accuracy of rolling elements. Cylindrical rollers are the core components of cylindrical roller bearings. 60%-70% of the bearing performance indicators depend on the manufacturing accuracy of cylindrical rollers. Therefore, it is urgent to develop new ultra-precision machining technologies to achieve high-precision machining of complex curved surfaces of high-performance rolling bearings. However, almost all high-end roller bearings for high-end civilian equipment in my country rely on imports, which seriously restricts the development of high-end equipment in my country. Therefore, the manufacturing of high-end roller bearings has been included in the major national development strategy.

[0003] Ultra-precision polishing is the last step in the final processing of key components of high-end equipment. It directly determines the geometric accuracy and shape error of the components. The results of ultra-precision polishing have a vital impact on the quality and service life of the product. At present, the technologies developed for cylindrical roller processing mainly include the mainstream traditional processing methods of centerless grinding and centerless super-finishing, as well as non-traditional processing methods such as centering reciprocating super-finishing and magnetorheological polishing. The following is a brief introduction to each technology:

[0004] 1) Centerless grinding. Centerless grinding is a precision machining technology for the outer circle of shaft parts. Unlike centering machining methods such as turning, centerless grinding uses the outer circle of the workpiece itself as the positioning reference for machining. The machining equipment mainly includes grinding wheels, guide wheels, and pallets. The guide wheel drives the cylindrical roller to rotate, and at the same time, the grinding wheel grinds the cylindrical roller. The pallet mainly plays the role of fixing the cylindrical roller. The workpiece is supported by the support plate and the guide wheel and ground by the grinding wheel. The centerless grinder is a grinder that does not require the use of the workpiece axis. It consists of a grinding wheel, an adjusting wheel, and a workpiece frame. The upper surface of the support plate is inclined by 30 to 50°, so that the workpiece is tightly pressed on the guide wheel by the cutting force. The axis of the guide wheel has an inclination angle α (1 to 5°) relative to the axis of the grinding wheel. It mainly consists of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece frame. The grinding wheel actually performs the grinding work, and the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece. During the machining process, defects such as spiral lines, vibration lines, and irregular scratches are prone to appear on the roller surface. At present, cylindrical rollers are generally processed by centerless external grinding, but it is difficult to obtain high-precision and high-consistency surface quality.

[0005] 2) Centerless super finishing. Super finishing is a process in which the workpiece is ground by the vibration of the abrasive. In this process, the tool has a very high speed so that it can remove excess material when it contacts the rotating workpiece. It inherits the advantages of high production efficiency of the centerless grinding method. It is mainly used to greatly improve the surface quality and shape accuracy of the outer cylindrical surface of the workpiece, and can also achieve micro-convexity forming. It is usually used as the final process of cylindrical roller processing. The centerless super finishing device consists of two guide rollers with the same shape and size and spiral grooves, as well as an oilstone and a pressure device. During the processing, the two guide rollers rotate at the same speed and in the same direction, and the cylindrical roller rotates under the drive of the guide roller. At the same time, the spiral groove of the guide roller drives the workpiece to move axially, and the oilstone above contacts the cylindrical roller to achieve micro-removal under a certain pressure. At present, the efficiency of centerless super finishing needs to be improved. In addition, the installation accuracy of the guide roller itself (the spacing and inclination of the guide roller axis) has a great influence on the processing effect, and the equipment requirements are high.

[0006] 3) Centering reciprocating super finishing. Centering reciprocating super finishing is a method of processing cylindrical rollers by replacing the turning tool of a traditional lathe with an oilstone, and adding an ultrasonic vibration auxiliary device and a precision loading control device. During the processing, an axial ultrasonic vibration is applied to the oilstone, and reciprocating motion is achieved along the oscillation trajectory under the action of the ultrasonic vibration. The cylindrical roller reciprocates while rotating along the axis. Through the precision loading device, a certain amount of force is applied between the oilstone and the cylindrical roller to achieve material removal. To improve the processing quality, the oilstone can be replaced with materials such as abrasive belts and polyurethane polishing pads. The material removal rate of centering reciprocating super finishing is low, and only a single workpiece can be processed at a time, so the processing efficiency is low. In addition, the centering reciprocating super finishing equipment is relatively complex, and the reciprocating motion of the oilstone and the ultrasonic vibration frequency have a great influence on the roundness of the workpiece surface, and the production cost is relatively high.

[0007] In summary, it is difficult to obtain high-precision and high-consistency surface quality by centerless grinding, the efficiency of centerless superfinishing needs to be improved, and the equipment precision requirements are relatively high. The efficiency of centering reciprocating superfinishing is low. In addition, the centering reciprocating superfinishing equipment is relatively complex and the production cost is relatively high. Therefore, it is urgent to develop a cylindrical roller polishing technology with high automation, high efficiency, good effect, and green environmental protection. Summary of the invention

[0008] Traditional curved surface ultra-precision machining technology is limited by the principle of pure mechanical removal. The contact pressure during removal needs to reach the plastic yield limit of the material. The minimum removal thickness is limited, and the surface integrity is difficult to further improve. Various forms of damage are inevitably produced under the action of thermal-mechanical coupling, and the thermal deterioration layer on the workpiece surface is relatively thick. In order to solve the above problems, the present invention proposes a continuous cylindrical roller force rheological polishing device, which has a simple structure, a high degree of automation and high efficiency. Correspondingly, the present invention also provides a method for force rheological polishing of a cylindrical roller using the continuous cylindrical roller force rheological polishing device of the present invention, which method has good effect and is green and environmentally friendly.

[0009] A continuous cylindrical roller force rheological polishing device comprises a cylindrical roller feeding module, a carrier ring module, a polishing groove module and a cylindrical roller unloading module;

[0010] The cylindrical roller feeding module is used to carry the cylindrical rollers and transport the cylindrical rollers one by one to the carrier ring module;

[0011] The carrier ring module comprises a carrier ring, a friction wheel, a carrier ring rotating motor and a friction wheel rotating motor. The carrier ring is driven to rotate by the carrier ring rotating motor, and a plurality of loading grooves for loading cylindrical rollers are evenly distributed on its outer wall. The friction wheel is arranged in the carrier ring and is driven to rotate by the friction wheel rotating motor, and can drive the cylindrical rollers in the carrier ring to rotate by friction.

[0012] The polishing tank module is located at the lower end of the carrier ring module, and includes a polishing tank storing polishing liquid, a polishing conveyor belt arranged in the polishing tank, and a conveyor belt motor for driving the polishing conveyor belt to operate. The polishing conveyor belt polishes the cylindrical roller through the polishing liquid.

[0013] The cylindrical roller unloading module is used to unload the cylindrical roller from the carrier ring.

[0014] Furthermore, the cylindrical roller feeding module comprises a feeding air gun, and the feeding air gun is used to blow the cylindrical roller into the loading groove of the carrier ring.

[0015] Furthermore, the cylindrical roller feeding module also includes a slide and a feeding position sensor. The slide is used to carry the cylindrical roller and has an inclined feeding channel. The feeding position sensor is used to monitor whether there is a vacant loading slot on the carrier ring.

[0016] Furthermore, openings for exposing the side surfaces of the cylindrical rollers are provided on the outer side and the inner side of the loading groove of the carrier ring.

[0017] Furthermore, the cylindrical roller unloading module comprises a discharge air gun, and the discharge air gun is used to blow the cylindrical roller out of the carrier ring.

[0018] Furthermore, the cylindrical roller unloading module also includes a timer, a discharge distance sensor and a cylindrical roller collection frame, the timer is used for timing, the discharge distance sensor is used to monitor whether there are cylindrical rollers in the loading groove of the carrier ring, and the cylindrical roller collection frame is used to collect cylindrical rollers blown out by the discharge air gun.

[0019] The present invention also provides a continuous cylindrical roller force rheological polishing method, which is implemented by using the above-mentioned device, comprising:

[0020] Step 1, loading the cylindrical roller onto the carrier ring through the cylindrical roller feeding module to achieve loading;

[0021] Step 2: The carrier ring is driven to rotate by the carrier ring driving motor, the friction wheel is driven to rotate by the friction wheel driving motor, the polishing conveyor belt is driven to operate by the conveyor belt motor, the carrier ring revolves with the cylindrical roller thereon, the friction wheel causes the cylindrical roller on the carrier ring to rotate by friction, and the polishing conveyor belt polishes the cylindrical roller by polishing liquid;

[0022] Step 3: After polishing is completed, the cylindrical roller in the carrier ring is removed through the cylindrical roller unloading module to achieve unloading.

[0023] Compared with the prior art, the beneficial effects of the technical solution of the present invention are mainly manifested in:

[0024] 1) High degree of polishing automation. The position signal is used to control the automatic circulation of the cylindrical roller to load and unload materials, so as to realize efficient polishing of the cylindrical roller. This cylindrical roller automatic polishing machine does not require human participation, and can be carried out according to requirements, through automatic detection, information processing, analysis and judgment, and operation and control. After a certain period of polishing, a whole batch of cylindrical rollers can be polished with high efficiency and high surface quality to achieve the expected goal. The use of the present invention can not only liberate people from heavy physical labor, part of mental labor, and harsh and dangerous working environments, but also expand the functions of human organs and greatly improve labor productivity.

[0025] 2) High polishing efficiency. The cylindrical roller workpiece and the polishing liquid move relative to each other. The polishing liquid in contact with the workpiece is sheared and undergoes shear thickening. The viscosity of the polishing liquid in this area increases sharply, forming particle clusters, which enhance the holding force on the abrasive particles and produce a micro-cutting effect on the workpiece surface. The shear thickening phenomenon is selective in the removal of workpiece surface materials, and can preferentially remove micro-convex peaks on the workpiece surface, so that the workpiece surface material quickly reaches a smooth state with high efficiency and good surface quality, thereby efficiently removing surface materials. The device can achieve continuous polishing of cylindrical rollers without manual operation, greatly improving processing efficiency and reducing costs.

[0026] 3) Ultra-precision machining of cylindrical roller surfaces. The cylindrical roller workpiece and the polishing liquid move relative to each other. The polishing liquid in contact with the workpiece is sheared and undergoes shear thickening. The viscosity of the polishing liquid in this area increases sharply, forming particle clusters, which enhance the holding force on the abrasive particles and form a flexible "fixed abrasive tool" that fits well with the cylindrical roller surface. This flexible "fixed abrasive tool" produces a micro-cutting effect on the workpiece surface, efficiently removing the surface material to obtain a smooth surface. The mechanorheological properties of the polishing liquid ensure that the flexible fixed abrasive tool it forms can adapt to surfaces of different curvatures, and also ensure that it has sufficient mechanical force to micro-cut the micro-peaks on the surface, thereby achieving ultra-precision machining of the cylindrical roller surface.

[0027] 4) Green and environmentally friendly. The materials used in the polishing process are all environmentally friendly materials, and the polishing fluid is green and pollution-free, reducing pollution emissions, and conforming to the concept of green environmental protection. Mechanorheological polishing fluid is a water-based polishing fluid, the main components of which are water, polyhydroxy polymers and abrasives. It is environmentally friendly and low in cost. The processing equipment is simple, does not require the addition of other auxiliary fields such as chemistry, electrochemistry, and ultrasound, and has low equipment cost and high reliability.

[0046] Example 2

[0047] See also Fig. 9 A continuous cylindrical roller force rheological polishing method is implemented using the device described in Example 1, comprising the following steps:

[0048] Step 1: Load the cylindrical rollers onto the carrier ring 21 through the cylindrical roller feeding module 1 to achieve loading.

[0049] Specifically, when the cylindrical roller feeding module 1 detects a vacant station through the feeding position sensor 12, the feeding air gun 13 blows the unpolished cylindrical roller into the carrier ring module station.

[0050] Step 2, the carrier ring 21 is driven to rotate by the carrier ring driving motor 22, the friction wheel 24 is driven to rotate by the friction wheel driving motor 23, and the polishing conveyor belt 33 is driven to operate by the conveyor belt motor 34. The carrier ring 21 revolves with the cylindrical roller thereon, the friction wheel 24 causes the cylindrical roller on the carrier ring 21 to rotate by friction, and the polishing conveyor belt 33 polishes the cylindrical roller through the polishing liquid.

[0051] Specifically, the carrier ring module 2 has two motors for rotation and revolution, namely, the carrier ring rotating motor 22 and the friction wheel rotating motor 23. Driven by the friction wheel rotating motor 23, the cylindrical roller can achieve uniform polishing of each position of the cylindrical surface. The carrier ring rotating motor 22 achieves the effect of polishing multiple cylindrical rollers at the same time.

[0052] The polishing conveyor belt 33 of the polishing tank module 3 drives the dynamic rheological polishing liquid 32 to move, so that the high-speed relative movement between the dynamic rheological polishing liquid 32 and the cylindrical roller workpiece produces a dynamic rheological effect, and the flexible fixed abrasive formed contacts the micro-convex peaks on the surface of the polishing workpiece. The dynamic rheological polishing is selective and can preferentially remove the micro-convex peaks on the surface, and the polishing efficiency is high. Moreover, it has a good fitting effect on the cylindrical roller curved surface material and a good polishing effect. At the same time, the dynamic rheological polishing liquid 32 is a water-based solution with a large specific heat capacity, which can effectively suppress the influence of heat.

[0053] Step 3, after polishing is completed, the cylindrical rollers in the carrier ring 21 are removed by the cylindrical roller unloading module 4 to achieve unloading.

[0054] Specifically, the cylindrical roller unloading module 4 is started after the time set by the timer 41 is reached, and the cylindrical roller after polishing is blown out through the detection of the discharge distance sensor 42, and then step 1 is repeated.
