Description

TECHNICAL FIELD

[0001] The application relates to the technical field of motor processing, and particularly relates to a polishing equipment and polishing assembly for an oil distribution plate. BACKGROUND

[0002] In the machining and production of the oil distribution plate, which is a core component of a hydraulic motor, the polishing process is a key link for guaranteeing the sealing performance, transmission efficiency and service life of the oil distribution plate. The oil distribution plate needs to be polished to ensure the flatness of the plate surface so as to reduce the leakage of hydraulic oil.

[0003] However, the clamping mechanism of the conventional polishing equipment and polishing assembly for the oil distribution plate adopts an edge clamping mode, that is, a clamping force is applied to the edge area of the oil distribution plate by a clamping jaw or a pressing plate to fix the oil distribution plate. Although this mode can initially fix the oil distribution plate, the edge of the plate surface and part of the side surface of the oil distribution plate are easily blocked, so that only the polishing of the local surface of the oil distribution plate can be completed in a single clamping. If the plate surface and the side surface of the oil distribution plate need to be polished comprehensively, the clamping position needs to be adjusted for multiple times, which increases the operation process and clamping time. In addition, the polishing medium of the conventional polishing assembly is usually a fixed grinding head or a polishing belt. The surface of the grinding head or the polishing belt is easily worn after long-term use, which reduces the polishing capacity. The grinding head needs to be replaced with a new one to continue the operation. During the replacement of the grinding head, the equipment is completely idle, which prolongs the overall machining cycle of the oil distribution plate. Especially in the batch production scene, the efficiency loss caused by the frequent replacement of the grinding head is more significant. Moreover, the surface of the grinding head or the polishing belt is easily attached with metal scraps during the polishing process. If the scraps are not cleaned in time, the scraps will repeatedly rub against the surface of the oil distribution plate with the rotation of the polishing medium, which not only easily leaves scratches on the surface of the oil distribution plate, but also accelerates the wear of the polishing medium, thereby reducing the machining quality.

[0004] Therefore, the application provides a polishing equipment and polishing assembly for an oil distribution plate to solve the above problems. SUMMARY

DETAILED DESCRIPTION

[0021] Embodiment 1 The present embodiment provides a polishing equipment for oil distribution plate and a polishing assembly, asFigures 1-5 As shown, the oil distribution disc polishing device comprises a base 1, a casing 2 fixedly arranged on the base 1, a clamping mechanism 3 arranged on the base 1 and located in the casing 2 for fixing and rotating the oil distribution disc, and two polishing mechanisms 4 arranged on the casing 2 and respectively located above the clamping mechanism 3 and on one side of the clamping mechanism 3 for polishing the surface and the side surface of the oil distribution disc; the clamping mechanism 3 comprises a fixed seat 31 fixedly installed on the base 1 and located in the casing 2, a rotating disc 32 rotatably arranged on the fixed seat 31, a rotating motor 33 fixedly installed in the fixed seat 31 for driving the rotating disc 32 to rotate, and an inner support assembly 34 arranged on the rotating disc 32 for positioning, supporting and clamping the oil distribution disc through the central hole of the oil distribution disc.

[0022] In use, first, the oil distribution disc to be polished is placed above the rotating disc 32 of the clamping mechanism 3, so that the central hole of the oil distribution disc is aligned with the inner support assembly 34, and the inner support assembly 34 is abutted from the inside of the central hole of the oil distribution disc to realize the positioning, supporting and clamping of the oil distribution disc on the rotating disc 32, then the rotating motor 33 in the fixed seat 31 is started, which drives the rotating disc 32 to rotate around the fixed seat 31, at this time, the rotating disc 32 drives the clamped oil distribution disc to rotate synchronously, then the two polishing mechanisms 4 above and on one side of the clamping mechanism 3 on the casing 2 are used, the polishing mechanism 4 above polishes the surface of the rotating oil distribution disc, and the polishing mechanism 4 on one side polishes the side surface of the oil distribution disc, during the whole polishing process, the base 1 provides stable mounting support for the casing 2 and the clamping mechanism 3, and the casing 2 protects the clamping mechanism 3 and the oil distribution disc inside to ensure the coordinated operation of the components to complete the polishing of the surface and the side surface of the oil distribution disc.

[0023] Specifically, the inner support assembly 34 comprises a sliding groove 341 opened on the rotating disc 32, a bidirectional screw 342 rotatably connected in the sliding groove 341, a sliding block 343 symmetrically and slidably connected in the sliding groove 341 and screwed with the bidirectional screw 342, a supporting block 344 fixedly installed on the two sliding blocks 343 for abutting from the inside of the central hole of the oil distribution disc to realize clamping, and a servo motor 345 fixedly installed in the rotating disc 32 for driving the bidirectional screw 342 to rotate; When it is necessary to clamp and fix the oil distribution disc, first start the servo motor 345 in the rotating disc 32, the servo motor 345 will drive the bidirectional screw 342 rotatingly connected in the sliding groove 341 to rotate, since the two sliding blocks 343 are symmetrically slidingly connected in the sliding groove 341 and are screwed with the bidirectional screw 342, and the screw thread directions of the two ends of the bidirectional screw 342 are opposite, therefore, when the bidirectional screw 342 rotates, it will drive the two sliding blocks 343 to synchronously slide along the sliding groove 341 in opposite directions, with the sliding of the sliding blocks 343, the support blocks 344 fixedly installed thereon will synchronously approach the center hole of the oil distribution disc, until the support blocks 344 are tightly abutted against the hole wall from the inner side of the center hole of the oil distribution disc, that is, the positioning and clamping of the oil distribution disc are completed, conversely, when the oil distribution disc needs to be removed, only the servo motor 345 needs to be started to rotate reversely, to drive the bidirectional screw 342 to reversely rotate, so that the two sliding blocks 343 slide away from each other along the sliding groove 341, and the support blocks 344 move away from the center hole of the oil distribution disc along with the sliding blocks 343, to release the clamping state of the oil distribution disc.

[0024] Further, to ensure the effect of the inner support assembly 34 fixing the oil distribution disc, the side of the support block 344 close to the oil distribution disc is fixedly provided with anti-skid lines 3441, when the support block 344 abuts against the inner wall of the center hole of the oil distribution disc, the anti-skid lines 3441 will increase the friction between the support block 344 and the inner wall of the center hole of the oil distribution disc, to further strengthen the fixing stability of the inner support assembly 34 to the oil distribution disc, to reduce the problems of uneven polishing surface and size precision deviation caused by sliding, to provide reliable guarantee for improving the polishing quality of the oil distribution disc.

[0025] In addition, to seal and protect the threaded connection part of the bidirectional screw 342 and the sliding block 343, the inner support assembly 34 further comprises a corrugated pipe sleeve 346 fixedly connected between the two sliding blocks 343 and on the side of the two sliding blocks 343 away from each other and located in the sliding groove 341, the corrugated pipe sleeve 346 is sleeved outside the bidirectional screw 342, and the corrugated pipe sleeve 346 located on the side of the two sliding blocks 343 away from each other is fixedly connected with the side wall of the sliding groove 341; the corrugated pipe sleeve 346 is sleeved outside the bidirectional screw 342 and is connected between the two sliding blocks 343 and between the sliding block 343 and the side wall of the sliding groove 341, to form a full-sealing structure for the threaded connection area of the bidirectional screw 342 and the sliding block 343, when the sliding block 343 slides along the sliding groove 341, the corrugated pipe sleeve 346 can deform by stretching and contracting along with the movement of the sliding block 343, to always maintain the sealing of the transmission area, so as to block the metal chips generated in the polishing process from entering the thread gap, to further reduce the problems of thread jamming and wear aggravation caused by impurities, to guarantee the smoothness and precision of the transmission of the bidirectional screw 342, and to prolong the service life of the inner support assembly 34.

[0026] Example 2 Different from example 1, as shown in FIG. 6, the inner support assembly 34 of the oil distribution disc clamping device 3 comprises a rotating disc 32, a bidirectional screw 342, two sliding blocks 343 and two support blocks 344. Figures 6-8As shown, the present application also provides a polishing assembly for the oil distribution plate polishing device, the polishing mechanism 4 comprises a polishing belt 41, a driving assembly 42 arranged on the casing 2 for moving the polishing belt 41 close to or away from the oil distribution plate, a winding and unwinding assembly 43 arranged on the driving assembly 42 and connected with both ends of the polishing belt 41 for winding one end of the polishing belt 41 and unwinding the other end, a cleaning assembly 44 arranged on both sides of the winding and unwinding assembly 43 for cleaning the surface of the polishing belt 41, and a compression roller 45 arranged on the driving assembly 42 for pressing the polishing belt 41 on the surface of the oil distribution plate.

[0027] In use, when the oil distribution plate needs to be polished, the driving assembly 42 on the casing 2 is started first, which drives the polishing belt 41, the winding and unwinding assembly 43, the cleaning assembly 44 and the compression roller 45 to move synchronously until the polishing belt 41 is close to the surface of the oil distribution plate to be polished, and at the same time the compression roller 45 presses the polishing belt 41 on the surface of the oil distribution plate, ensuring that the polishing belt 41 and the oil distribution plate maintain stable contact pressure, then the polishing belt 41 starts to polish the surface or side of the oil distribution plate, when the polishing belt 41 is partially worn, the winding and unwinding assembly 43 on the driving assembly 42 is started, which is connected with both ends of the polishing belt 41, and through winding one end of the polishing belt 41 and unwinding the other end, the unworn area of the polishing belt 41 is moved to the polishing position and the worn area is separated from the working area, in this process, the cleaning assembly 44 arranged on both sides of the winding and unwinding assembly 43 works synchronously to clean the surface of the worn polishing belt 41 before winding and the surface of the unworn polishing belt 41 after unwinding, avoiding the influence of debris on the polishing quality or the interference of the running of the winding and unwinding assembly 43, ensuring the continuous and stable polishing work.

[0028] Specifically, the driving assembly 42 comprises a connecting plate 421 arranged in the casing 2, an air cylinder 422 fixedly installed on the casing 2 and fixedly connected with the center position of the connecting plate 421, two guide rods 423 respectively slidingly connected with the casing 2 and fixedly connected with both sides of the connecting plate 421, and a limiting block 424 fixedly connected with one end of the guide rod 423 away from the connecting plate 421 for preventing the guide rod 423 from being separated from the casing 2, and the compression roller 45 is fixedly connected with the center position of the one side of the connecting plate 421 away from the air cylinder 422; When it is necessary to adjust the distance between the polishing belt 41 and the oil distribution disc by means of the polishing mechanism 4, the cylinder 422 fixedly installed on the shell 2 is started first, and the piston rod of the cylinder 422 will push or pull the connecting plate 421 fixedly connected with the center position thereof, and drive the connecting plate 421 to move away from the center position of the fixedly installed pressing roller 45 and the winding and unwinding assembly 43 and the polishing belt 41 on the connecting plate 421 synchronously. In this process, the two guide rods 423 fixedly connected with the connecting plate 421 on both sides and slidingly connected with the shell 2 will move synchronously along the sliding path of the shell 2 with the connecting plate 421, limit the moving direction of the connecting plate 421, and avoid deviation thereof. At the same time, the limiting block 424 fixedly connected with the guide rod 423 away from the connecting plate 421 will be in contact with the inner wall of the shell 2 when the guide rod 423 moves, prevent the guide rod 423 from being separated from the shell 2, and drive the connecting plate 421 to move to the polishing position adapted to the oil distribution disc with the polishing belt 41 until the pressing roller 45 is in close contact with the polishing belt 41 and presses the polishing belt 41 on the surface of the oil distribution disc, so as to complete the position and pressure adjustment before polishing. Conversely, when it is necessary to move away from the oil distribution disc, the cylinder 422 is started in reverse, and the connecting plate 421 and the winding and unwinding assembly 43, the polishing belt 41 and other components are driven synchronously.

[0029] It should be noted that the cylinder 422 on the polishing mechanism 4 at the position above the clamping mechanism 3 is fixed to the top of the shell 2 and the guide rod 423 slides on the top of the shell 2, and the cylinder 422 on the polishing mechanism 4 at one side of the clamping mechanism 3 is fixed to the side wall of the shell 2 and the guide rod 423 slides on the side wall of the shell 2.

[0030] Further, the winding and unwinding assembly 43 comprises the first bracket 431 fixedly installed symmetrically on the connecting plate 421 and located at the positions on both sides of the pressing roller 45, the two winding rollers 432 rotatably connected with the two first brackets 431 respectively for winding and unwinding the polishing belt 41 at one end and the other end respectively, and the two drive motors 433 fixedly connected with the two first brackets 431 respectively for making the rotating directions of the two winding rollers 432 opposite, and the polishing belt 41 is fixedly connected with the two winding rollers 432 at both ends respectively. When it is necessary to replace the polishing belt 41 dynamically, two drive motors 433 fixed on the two first supports 431 respectively are started, and the two drive motors 433 output power to drive the corresponding connecting winding rollers 432 to rotate in opposite directions. One of the winding rollers 432 rotates to wind the worn area of the polishing belt 41 on the roller body, and the other winding roller 432 rotates in the opposite direction to gradually loosen the unworn polishing belt 41 wound on it, so that the unworn area moves to the polishing position under the pressure roller 45. In this process, the first support 431 provides stable support for the winding roller 432 and the drive motor 433 to ensure that the winding roller 432 does not deviate when rotating, realizes continuous replacement of the polishing belt 41, maintains the sharpness of the polishing belt 41 without stopping, and ensures continuous polishing operation.

[0031] Further, the cleaning assembly 44 includes second supports 441 fixed symmetrically on the connecting plate 421 and located on the side of the two first supports 431 away from the pressure roller 45, two cleaning rollers 442 rotatably connected to the two second supports 441 respectively, two brushes 443 fixed on the two cleaning rollers 442 respectively and uniformly distributed for cleaning the surface of the polishing belt 41, and transmission assemblies 444 arranged on the two cleaning rollers 442 and the two winding rollers 432 respectively for transmitting the rotating power of the winding roller 432 to the corresponding cleaning roller 442. When the winding roller 432 of the winding and unwinding assembly 43 rotates under the drive of the drive motor 433, the transmission assembly 444 arranged on the cleaning roller 442 and the corresponding winding roller 432 transmits the rotating power of the winding roller 432 to the cleaning roller 442, and drives the two cleaning rollers 442 to rotate synchronously on the corresponding second supports 441. In the rotating process of the cleaning roller 442, the brushes 443 uniformly distributed on the surface of the cleaning roller 442 are in close contact with the surface of the moving polishing belt 41. The brushes 443 near the winding end remove the debris remaining on the surface of the worn area of the polishing belt 41, preventing the debris from being attached to the winding roller 432. The brushes 443 near the unwinding end clean the surface of the unworn polishing belt 41 that has not entered the polishing operation, preventing the debris from scratching the oil pan during polishing. Finally, the polishing belt 41 is cleaned in real time during the entire winding and unwinding process, ensuring smooth operation of the polishing quality and the winding and unwinding assembly 43.

[0032] In addition, in order to ensure the cleaning of the debris, the brush 443 is a nylon brush or a pig bristle brush; the nylon brush has moderate hardness and strong wear resistance, is suitable for cleaning fine and low-hardness polishing debris, and is not prone to hair loss; the pig bristle brush has good toughness and strong cleaning force, is suitable for cleaning coarse or strongly adhered debris, can deeply clean the impurities in the surface gap of the polishing belt 41, and both of them are flexible materials and will not scratch the surface of the polishing belt 41 when contacting the polishing belt 41, so that the type of the brush 443 can be flexibly selected according to the particle size of the polishing belt 41, the material of the oil distribution disc and the type of the debris, and efficient cleaning can be realized in different polishing scenes, the flexible brush 443 can avoid damaging the polishing belt 41, prolong the service life of the polishing belt 41, and improve the flexibility of the equipment.
