Detailed Description
In order to more clearly illustrate the embodiments of the present invention, the following description will explain the embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
As shown in fig. 1, a bidirectional-feeding linear hydraulic polishing device comprises a frame 10, a transverse feeding mechanism 20, a longitudinal feeding mechanism 30, and a rotary polishing mechanism 40, wherein both the transverse feeding mechanism 20 and the longitudinal feeding mechanism 30 are movably mounted on the frame, and the rotary polishing mechanism 40 is fixed on the longitudinal feeding mechanism 30.
The frame 10 includes a base 11 and two vertical columns 12, the base 11 is horizontally disposed, and the two vertical columns 12 are disposed in parallel and fixed on the base 11. As shown in fig. 2, the base 11 has a first rail 18 for slidably mounting an infeed mechanism 20. As shown in fig. 3, the two columns 12 are respectively provided with second guide rails 19 arranged oppositely for slidably mounting the longitudinal feeding mechanism 30.
The traverse mechanism 20 includes a table 21, a polishing tank 22, a rack 23, a gear 24, and a servo motor 25. The workbench 21 is installed on the first guide rail 19 in a sliding fit mode, the cross section of the first guide rail is provided with a dovetail groove structure, the bottom of the workbench is provided with a tenon structure with the same cross section, and the workbench are installed in a sliding mode. A rack 23 is fixed on the side surface of the workbench 21, a gear 24 is arranged on the base 11, and the rack is connected with a servo motor 25 through a connecting rod and a coupling. As shown in FIG. 4, the gear 24 is engaged with the rack 23, and when the servo motor 25 is actuated, the table 21 is fed laterally. Contact inductors are arranged at the stroke limit positions at the two ends of the base 21, and limit columns are arranged at the two ends of the workbench. In order to realize reciprocating feeding of the base during polishing, contact sensors are arranged at two ends of the base, limiting columns are arranged at two ends of the workbench, and when the limiting columns move to the positions above the contact sensors, the limiting columns are triggered to send electric signals to the servo motor, so that the servo motor changes the rotating direction. When the workpiece is polished, the workbench can realize reciprocating feeding, so that polishing ripples on the surface of the workpiece can be eliminated, and uneven polishing of transverse points of the workpiece is avoided. A workpiece rack 26 is arranged in the polishing groove 22, an electromagnet is arranged in the workpiece rack 26, and when a metal workpiece to be polished is placed on the workpiece rack, the electromagnet is electrified to generate a magnetic field to fix the workpiece.
As shown in fig. 5, the longitudinal feeding mechanism 30 includes a screw holder 31, a lead screw 32, a first worm wheel 33, a first worm 34, a rocking handle 35, a second worm wheel 36, a second worm 37, and a fine adjustment knob 38. The screw 32 is longitudinally arranged and rotatably mounted to the frame 10. The threaded seat 31 is slidably fitted between the two second guide rails 19, the threaded seat 31 is threadedly fitted to the lead screw 32, and the rotary polishing mechanism 40 is mounted on the threaded seat 31. When the screw 32 is rotated, the rotation of the screw holder 31 in the horizontal plane is restricted by the second guide rail 19, which can only be fed longitudinally in the direction of the screw. Due to the uniformity of the screw threads of the screw rod, the longitudinal displacement of the screw seat is constant when the screw rod rotates for one circle. Further, the size of the longitudinal displacement can be adjusted by setting the thread pitch of the screw rod threads, namely when the longitudinal adjustment with higher precision is required, the screw rod and the thread seat with smaller thread pitch under the same screw rod diameter can be replaced, so that when the screw rod rotates for one circle, the longitudinal displacement of the thread seat is smaller. The first worm wheel 33 is coaxially fixed at the bottom of the screw 32 and is matched with a first worm 34, the first worm 34 is rotatably arranged on the base 11 and is connected with a rocking handle 35 through a connecting rod and a coupling. When the rocking handle 35 is rotated, the first worm 34 is linked with the first worm wheel 33 and drives the screw rod 32 to rotate, so that the longitudinal displacement of the threaded seat 31 is realized.
For the polishing roller based on the linear hydraulic pressure, the polishing gap is required to be controlled within 20-200 μm. In order to more accurately realize the longitudinal adjustment of the threaded seat, a worm gear is added on the basis of the transmission mechanism. The second worm wheel 36 is coaxially connected with the first worm 34, the second worm 37 is coaxially connected with the fine adjustment knob 38, and the second worm 37 is coupled with the second worm wheel 36 in a linkage manner. Due to the addition of the first worm gear, i.e., the second worm wheel 36 and the second worm 37, the reduction ratio from the rotation input end to the rotation output end is further increased, and fine adjustment with a precision of 10 μm can be realized, thereby improving the adjustment precision of the screw base. After the workpiece is placed in the station, the rocking handle 35 is rotated to enable the rotary polishing mechanism to rapidly enter the processing station, and then the fine adjustment knob 38 is rotated to adjust the polishing roller to a required polishing clearance.
The rotary polishing mechanism 40 comprises a rotating motor 41 and a polishing roller 42, wherein the rotating motor 41 is mounted on the threaded seat 31 of the longitudinal feeding mechanism, and the rotating motor 41 and the threaded seat 31 are integrated in the longitudinal box body. The shaft of the rotary motor 41 passes through the case, and a burnishing roller 42 is mounted on the end of the shaft. The polishing rollers 42 are disposed in the polishing receptacle 22 in a clearance fit with a workpiece to be polished mounted on the workpiece holder 26.
As shown in FIG. 6, the main body of the polishing roller 42 has a cylindrical structure with a diameter of 200mm and a thickness of 30mm, and is made of an aluminum alloy material. The circumferential surface of the micro-groove structure is uniformly distributed with micro-groove structures 43 used for generating dynamic pressure, the micro-groove structures 43 comprise arc parts 44 of the circumferential surface and micro-groove parts 45 extending along the circumferential direction of the circumferential surface, and the micro-groove parts are formed by wire cutting.
As shown in fig. 7, when the polishing roller 42 and the to-be-polished member move relatively during polishing, the polishing liquid flows from the micro-groove portion 45 with a large gap between the to-be-polished member and the micro-groove structure to the arc portion 44 with a small gap to form a dynamic pressure lubricating film, and the surface material of the workpiece is uniformly and rapidly removed under the dual actions of the abrasive particles and the dynamic pressure lubricating film. The microgrooves 45 are optimally designed and have a geometry that ensures that a strong and uniform hydrodynamic pressure is generated as the polishing roller 42 rotates. The projection of the micro-groove 45 along the axial direction of the polishing roller 42 is a parabola or a straight line, the central angle is 12-18 degrees, the optimum is 18 degrees, and the maximum depth of the micro-groove 45 is 1-3mm, the optimum is 1 mm. The parabolic micro-groove part 45 and the arc surface 44 with the radian not larger than the micro-groove part form a parabolic micro-groove structure, and the linear micro-groove part 45 and the arc surface 44 with the radian not larger than the micro-groove part form a wedge-shaped micro-groove structure. The number of micro-groove structures 43 is set to an even number, preferably twelve. In the twelve microgroove structures, the parabolic microgroove structures and the wedge-shaped microgroove structures are sequentially alternated, or the two parabolic microgroove structures and the two wedge-shaped microgroove structures are sequentially alternated, or the three parabolic microgroove structures and the three wedge-shaped microgroove structures are sequentially alternated, or the six parabolic microgroove structures and the six wedge-shaped microgroove structures are sequentially alternated. Wherein, the effect is the best when three parabola-shaped micro-groove structures and three wedge-shaped micro-groove structures are sequentially and alternately used. A30 mm unthreaded hole is formed in the center of the polishing roller, and a counter bore with the diameter of 110mm and the depth of 15mm is coaxially arranged and used for being connected with a shaft of the rotating motor 41.
The polishing process comprises the following specific implementation steps:
workpiece fixing and early preparation: the workpiece is flatly fixed at the center of the workpiece holder 26 by paraffin, the workpiece holder 26 is fixed at the center inside the polishing tank 22 by electromagnetic suction, and the polishing solution is added into the polishing tank to a specified scale mark.
Transverse feeding: the servo motor 25 is started to drive the gear 24 to rotate through the shaft, and the rack 23 drives the transverse worktable 21 to perform transverse feeding along with the rotation, thereby moving the polishing trough 22 on the transverse worktable 21 to be right below the polishing roller 42.
Longitudinal feeding: the rocking handle 35 is rotated to transmit the torque to the turbine 33 fixed at the tail end of the screw rod 32 through a shaft, a connecting rod and a worm, the screw rod 32 rotates to drive the longitudinal box body fixed on the screw rod nut seat 31 to do longitudinal descending motion, and the polishing roller 42 also descends along with the longitudinal descending motion. When the burnishing roller approaches the workpiece, it is instead indexed longitudinally by a worm 37 rotatably fixed to the shield. Until the workpiece is just touched, the corresponding scales of the worm 37 are reversely rotated according to the polishing clearance required by the experiment, so that the feeding of the polishing clearance required by the experiment is accurately finished.
Polishing: the rotary motor 41 is started to transmit power to the polishing roller 42 through the shaft, and the polishing roller is driven to rotate at a high speed. Meanwhile, the servo motor 25 is controlled to output positive and negative rotation power in a designated period, so that the workpiece in the polishing groove 22 can do reciprocating motion with small amplitude. The high-speed rotating polishing roller 42 with a composite structure can generate a large and uniform linear pressure field in a narrow polishing gap by virtue of the microstructure units on the circumferential surface of the polishing roller, and drives abrasive particles to impact the surface of a workpiece, so that efficient and uniform polishing is completed.
Disassembling the workpiece: after finishing the polishing process for a prescribed time, the rotary motor 41 and the servo motor 25 are turned off, the rocking handle 35 is rotated, and the polishing roller 42 is lifted up by the longitudinal feed mechanism. Then the servo motor 25 is started, the gear 24 rotates reversely, and the polishing groove 22 is withdrawn from the station. The electromagnetic attraction is turned off, the workpiece holder 26 is taken out from the bottom of the polishing tank, and finally the polished workpiece is removed by heat treatment.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
