Description

Technical Field

[0001] The present invention relates to the technical field of polishing equipment, and particularly to a rolling separation polishing equipment. Background Art

[0002] In the field of precision machinery manufacturing, the batch polishing process of parts is a key technology to achieve high surface quality and batch consistency. Due to the requirements of high conductivity, low contact impedance, and corrosion resistance, the surface roughness usually needs to be controlled within a certain range. Therefore, it is necessary to perform batch polishing on the processed parts.

[0003] In the existing polishing equipment, traditional mechanical grinding relies on centrifugal force to drive abrasives (such as alumina or silicon carbide particles). However, simple mechanical rotation easily leads to uneven distribution of abrasives. During operation, in the circular motion process of the existing equipment, local accumulation is likely to occur, making it inconvenient to turn over and move, and it is easy to have inconsistent local grinding progress. The existing equipment does not consider separating the internal metal chips. As a result, after polishing, the parts need to be cleaned multiple times, and the non-separation of metal chips is also likely to cause accumulation on the surface of local parts, affecting the subsequent grinding consistency and resulting in an increase in the defective rate during batch processing. For this reason, we propose a rolling separation polishing equipment to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a rolling separation polishing equipment to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A rolling separation polishing equipment, including,

[0006] A connecting seat, on the top of which there is a polishing cylinder. A buffer telescopic rod is provided between the polishing cylinder and the connecting seat. Inside the polishing cylinder, there are respectively a driving shaft and a recovery cylinder. The recovery cylinder is annular and concentric with the driving shaft. The bottom edge of the polishing cylinder is arc-shaped and extends to the bottom of the outer wall of the recovery cylinder for part conduction;

[0007] Among them, a transmission ring is movably provided on the driving shaft. Multiple limit sliding rails for installing separation frames are provided outside the transmission ring. The separation frames rotate with the driving shaft to turn over the parts, ensuring uniform grinding and discharging the debris into the recovery cylinder;

[0008] Inside the recovery cylinder, there are multiple groups of electromagnetic plates. A hollow sliding plate is clamped at the front end of the electromagnetic plates for unified adsorption and recovery of metal chips. When polishing metal parts, the abrasive corresponding to the parts box can be evenly poured into the grinding cylinder. As the driving shaft rotates as a whole, it can drive the separation frame to move in a circular motion inside the grinding cylinder. Under the action of the arc surface at the bottom of the grinding cylinder, the metal parts can be gathered towards the middle, and the parts and the abrasive can be quickly and evenly distributed inside the grinding cylinder, enabling the surface of the parts to be polished. During the circular reciprocating motion of the parts, the generated metal chips and the like can enter the inside of the recovery cylinder under a certain magnetic effect, playing an auxiliary cleaning role and reducing the impact of metal chip accumulation on subsequent grinding and polishing.

[0009] Preferably, the separation frame is movably clamped at the bottom of the limit sliding rail. An activity shaft is movably clamped inside one side of the separation frame close to the recovery cylinder.

Multiple welding plates are installed inside the other side of the separation frame. A hinge shaft is clamped between the welding plate and the clamping rod;

[0010] Multiple arc-shaped clamping rings are evenly installed on the hinge shaft. A shrinkage tube is installed at the top of the arc-shaped clamping ring.

Multiple groups of symmetrically arranged transmission shafts are installed on the surface of the transmission plate. The transmission shafts are connected between the transmission plate and the activity shaft. The transmission shafts penetrate through the arc-shaped clamping ring and are fixedly connected with multiple activity insertion tubes inserted into the shrinkage tube. The bottom of the activity insertion tube is conical. Through the design of the cleaning ring and the activity insertion tube, the gaps of the parts can be dynamically cleaned during the polishing process, reducing the situation of residual debris and abrasives getting stuck, improving the overall processing quality of the equipment, and reducing the probability of abrasive jamming compared with traditional equipment.

[0012] Preferably, a transmission frame is movably clamped on the surface of the separation frame. Automatic reset hinge arms are movably arranged at both ends of the transmission frame.

Tooth grooves meshing with the transmission tooth are opened on both sides of the push insertion rod. One end of the push insertion rod abuts against one side of the transmission plate, which can play a driving role in pushing the transmission plate. Through the linkage design of the separation frame and the limit sliding rail, combined with the arc-shaped diversion structure at the bottom of the grinding cylinder, the driving shaft can drive the separation frame to perform a planetary motion, realizing the three-dimensional tumbling of the parts under the dual action of centrifugal force and centripetal force, making the surface roughness of the parts consistent and reducing the generation of defective products.

[0013] Preferably, a telescopic rod is provided at the top of the transmission frame, and the telescopic rod is clamped on the top of the side wall of the grinding cylinder. A plurality of transmission bumps corresponding to the articulated arms are installed on the inner wall of the grinding cylinder.

By using the buffer spring, buffer roller and telescopic rod, the vibration and noise during the operation of the equipment are reduced, the service life of the equipment is prolonged, and the working environment is improved.

[0014] Preferably, a plurality of positioning plates are installed inside the recovery cylinder, the electromagnetic plate is clamped between the positioning plates, a fixed groove for rotating a transmission roller is provided at the top of the electromagnetic plate, one end of the transmission ring is provided with a fixed shaft, and a transmission slider clamped with the limit slide rail is movably clamped inside the fixed shaft;

[0015] A transmission belt is provided between the bottom of the transmission slider and the top end of the hollow slide plate, and the transmission belt is attached to the transmission roller during the transmission process.

[0016] Preferably, a grid plate is provided on the surface of the hollow slide plate, and the grid plate is made of plastic material, which can reduce the docking of metal chips on the hollow slide plate under the magnetic action, reduce the metal chips remaining on the surface of the grid plate, and compared with the traditional metal mesh, it can reduce the situation of metal chip accumulation and blockage caused by its magnetization.

[0017] Preferably, a collection plate is inserted inside the hollow slide plate, and a plurality of inclined grooves are clamped on the collection plate for collecting and processing metal chips, which is convenient for the unified recovery of metal chips and prevents accidental export during the reciprocating movement of the hollow slide plate.

[0018] Preferably, a plurality of buffer springs are provided between the top of the connecting seat and the bottom of the grinding cylinder, which play a role in shock absorption and noise reduction.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer toFigures 1-8 , the present invention provides a technical solution: a rolling separation and polishing device, including,

[0035] a connecting seat 1, on the top of which there is a grinding cylinder 2, and a buffer telescopic rod is arranged between the grinding cylinder 2 and the connecting seat 1. Inside the grinding cylinder 2, there are respectively a driving shaft 3 and a recovery cylinder 5. The recovery cylinder 5 is annular and concentric with the driving shaft 3. The bottom edge of the grinding cylinder 2 is arc-shaped and extends to the bottom of the outer wall of the recovery cylinder 5 for part conduction;

[0036] Among them, a transmission ring 31 is movably arranged on the driving shaft 3, and a plurality of limit sliding rails 32 for installing separation frames 4 are arranged outside the transmission ring 31. The separation frames 4 rotate with the driving shaft 3 to turn the parts, ensuring uniform grinding and discharging the debris into the recovery cylinder 5;

[0037] Inside the recovery cylinder 5, there are a plurality of electromagnetic plates 52, and a hollow sliding plate 53 is clamped in front of the electromagnetic plates 52 for unified adsorption and recovery of metal chips. When it is necessary to polish metal parts, the parts and the corresponding abrasives can be evenly poured into the grinding cylinder 2. As the driving shaft 3 rotates as a whole, it can drive the separation frames 4 to move in a circular motion inside the grinding cylinder 2. And under the action of the arc surface at the bottom of the grinding cylinder 2, the metal parts can be gathered towards the middle, the parts and the abrasives can be quickly and evenly distributed inside the grinding cylinder 2, the surface of the parts can be polished, and during the circular reciprocating motion of the parts, the generated metal chips and the like can enter the recovery cylinder 5 under a certain magnetic action, playing an auxiliary cleaning role and reducing the influence of metal chip accumulation on subsequent grinding and polishing.

[0038] As Figure 4 and Figure 5 shown, in order to reduce the residual debris and the like inside the metal parts during polishing, the separation frames 4 are movably clamped at the bottom of the limit sliding rails 32. Inside one side of the separation frames 4 close to the recovery cylinder 5, a movable shaft 41 is movably clamped, the movable shaft 41 is movably clamped at the bottom of the inner wall of the grinding cylinder 2, and a plurality of clamping rods 411 are installed on the movable shaft 41. On the other side of the separation frames 4, a plurality of welding plates 43 are installed, and a hinge shaft 44 is clamped between the welding plates 43 and the clamping rods 411;

[0039] A plurality of arc-shaped clamping rings 45 are evenly installed on the hinge shaft 44, a shrinkage tube 451 is installed on the top of the arc-shaped clamping rings 45, and a plurality of cleaning rings are arranged on the outer wall of the shrinkage tube 451. The cleaning rings are generally made of alloy material. As the separation frames 4 move in a circular motion, the plurality of cleaning rings can brush the gaps of the metal parts, reducing the residual metal chips and also reducing the accidental situation of abrasives and the like being stuck in the parts.

[0040] As Figure 5 and Figure 6As shown in the figure, in order to ensure the reduction of the docking of internal parts, a through groove for the movement of the transmission plate 42 is provided on the side of the separation frame 4 away from the recovery cylinder 5. On the surface of the transmission plate 42, multiple groups of symmetrically arranged transmission shafts 46 are installed. The transmission shafts 46 are connected between the transmission plate 42 and the movable shaft 41. The transmission shafts 46 penetrate through the arc-shaped clamping ring 45 and are fixedly connected with a plurality of movable insertion tubes 461 inserted into the inside of the shrinkage tube 451. The bottom of the movable insertion tube 461 is conical. During the circular motion of the separation frame 4, when the transmission plate 42 follows and pushes the push rod 471 to move, the movable insertion tube 461 can reciprocate inside the shrinkage tube 451, enabling the shrinkage tube 451 to contract and expand, and enabling the nearby parts to be cleaned by the cleaning ring. Moreover, the movable insertion tube 461 can also push the internal parts to move, reducing the situation where the parts piled up at the bottom are not movable due to pressure and reducing the inconsistent surface friction degree.

[0041] As Figure 3 shown in the figure, in order to improve the turnover efficiency during the operation of the equipment, a transmission frame 47 is movably clamped on the surface of the separation frame 4. At both ends of the transmission frame 47, there are movably arranged articulated arms 48 with automatic reset. One end of the articulated arm 48 clamped inside the transmission frame 47 is provided with transmission teeth. A push rod 471 is inserted into the transmission frame 47. Tooth grooves meshing with the transmission teeth are provided on both sides of the push rod 471. One end of the push rod 471 abuts against one side of the transmission plate 42. The transmission frame 47 can cooperate with the transmission bump 21 to push the separation frame 4 to move inside the limit slide rail 32, quickly turning over the internal parts and reducing the situation where the continuous circular motion causes inconsistent grinding efficiency due to bottom accumulation.

[0042] As Figure 3 shown in the figure, in order to reduce the vibration generated during the operation of the equipment, a telescopic rod is provided on the top of the transmission frame 47, and the telescopic rod is clamped on the top of the side wall of the grinding cylinder 2. A plurality of transmission bumps 21 corresponding to the articulated arms 48 in position are installed on the inner wall of the grinding cylinder 2. A buffer roller is rotatably arranged at the outer end of the articulated arm 48 for pushing the overall movement of the separation frame 4 during the transmission process. The buffer roller abuts against the inner wall of the grinding cylinder 2, which can reduce the shaking of the grinding cylinder 2 during the overall operation.

[0043] As Figure 7 shown in the figure, a plurality of positioning plates 51 are installed inside the recovery cylinder 5. The electromagnetic plate 52 is clamped between the positioning plates 51. A fixed groove for rotating the transmission roller 54 is provided on the top of the electromagnetic plate 52. One end of the transmission ring 31 is installed with a fixed shaft 311. Inside the fixed shaft 311, a transmission slider 312 clamped with the limit slide rail 32 is movably clamped.

[0044] A transmission belt 541 is provided between the bottom of the transmission slider 312 and the top end of the hollow slide plate 53. During the transmission process, the transmission belt 541 is attached to the transmission roller 54. The electromagnetic plate 52 can generate a magnetic force insufficient to adsorb parts, and can adsorb dust and the like along the transmission holes on the surface of the recovery cylinder 5 onto the hollow slide plate 53, facilitating subsequent unified processing.

[0045] As Figure 8 shown, a grid plate is provided on the surface of the hollow slide plate 53, and the grid plate is made of plastic material, which can reduce the docking of metal chips on the hollow slide plate 53 under the magnetic action. Under the action of magnetic force, the metal chips can enter the collection plate 531 along the grid plate. Moreover, the plastic material will not generate magnetic force under the long-term magnetic action. Compared with the traditional metal grid plate, it can reduce the adsorption and accumulation of metal chips and reduce the blockage situation.

[0046] As Figure 8 shown, a collection plate 531 is inserted into the hollow slide plate 53. A plurality of inclined grooves are provided on the collection plate 531 in an inclined setting for collecting and processing metal chips. As the separation frame 4 reciprocates inside the limit slide rail 32, the transmission slider 312 can be moved, thereby pulling the transmission belt 541 to operate, and the hollow slide plate 53 can reciprocate inside the electromagnetic plate 52, enabling the metal chips and the like to quickly enter the inclined grooves inside the collection plate 531 along the grid plate.

[0047] As Figure 1 shown, a plurality of buffer springs are provided between the top of the connecting seat 1 and the bottom of the grinding cylinder 2, which can play a role in buffering and shock absorption and reduce the generation of noise.

[0048] Working principle: First, when the metal parts need to be polished, the corresponding abrasives in the parts box can be evenly poured into the grinding cylinder 2. As the driving shaft 3 rotates as a whole, the separation frame 4 can be driven to move in a circular motion inside the grinding cylinder 2. Under the action of the arc surface at the bottom of the grinding cylinder 2, the metal parts can be gathered towards the middle, and the parts and abrasives can be quickly and evenly distributed inside the grinding cylinder 2, enabling the surface of the parts to be polished. Moreover, during the circular reciprocating motion of the parts, the generated metal chips and the like can enter the recovery cylinder 5 under a certain magnetic action, playing an auxiliary cleaning role and reducing the impact of metal chip accumulation on subsequent grinding and polishing. As the separation frame 4 moves in a circular motion, the buffer rollers on the articulated arm 48 can abut against the inner wall of the grinding cylinder 2, playing a role in buffering and shock absorption during movement, extending the maintenance cycle of the separation frame 4, reducing labor costs, and the articulated arm 48 cooperates with the transmission convex block 21 to push the separation frame 4 to move as a whole at the bottom of the limit slide rail 32, enabling the parts to be evenly mixed together and reducing the occurrence of local accumulation;

[0049] Then, during the operation of the articulated arm 48, under the combined action of the transmission teeth and the tooth grooves, the pushing rod 471 can be driven to move, the internal transmission plate 42 can be pulled to move, the transmission shaft 46 can be pulled to change the position of the movable insertion tube 461, the shrinkage tube 451 can be wrapped around the conical surface at the bottom of the movable insertion tube 461, the outer deformation of the shrinkage tube 451 can be reset, the metal chips remaining on the surface of the cleaning ring can be quickly separated, and during the circular motion, a large number of metal chips can be accumulated outside the recycling cylinder 5 during the uniform turning of the metal parts;

[0050] Finally, when the electromagnetic plate 52 operates, it can generate a certain magnetic force, which will not generate sufficient suction force on the parts, avoiding the situation that some parts accumulate on the outer wall of the recycling cylinder 5 and affecting the normal operation of the equipment. And as the separation frame 4 reciprocates inside the limit slide rail 32, the transmission slider 312 can be activated, thereby pulling the transmission belt 541 to operate, enabling the hollow slide plate 53 to reciprocate inside the electromagnetic plate 52, and quickly guiding the metal chips and the like into the inclined groove inside the collecting plate 531 along the grid plate, facilitating subsequent unified collection and measurement, reducing the impact of metal chips on part grinding, and also reducing the subsequent cleaning pressure, thus overall improving the processing efficiency of the parts.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
