Description

Technical Field

[0001] This utility model relates to the field of water bath design technology, and in particular to a polishing device for reamer bolt holes. Background Technology

[0002] Currently, when machining bolt holes in sheet metal workpieces, most processes involve drilling with a reamer and then polishing with a polishing device to make the outer end of the bolt hole more aesthetically pleasing and remove burrs.

[0003] The applicant found that when grinding bolt holes on slab workpieces in the prior art, the grinding debris is often scattered and not concentrated, making it very inconvenient and troublesome to clean. It is easy to miss some debris during cleaning. Secondly, most of the current processing can only be carried out at a single station, resulting in low efficiency. Furthermore, when feeding continuously, manual feeding is often required, resulting in low accuracy and certain safety hazards.

[0004] Therefore, the applicant proposes a polishing device for reamer bolt holes to solve the problem. Utility Model Content

[0005] This invention provides a polishing device for reamer bolt holes, which solves the problems mentioned in the background.

[0006] To solve the above-mentioned technical problems, this utility model provides a polishing device for reamer bolt holes, including a device platform. Two recessed platforms are linearly mounted on the top of the device platform. A square frame is mounted on the top of the recessed platforms. Two support plates are fixed to the inner wall of the square frame. A grinding assembly is mounted on the device platform. The grinding assembly includes a square plate that rotates on the top of the device platform. Electric push rods are mounted at both ends of the bottom of the square plate, and a long shaft is mounted at the middle of the bottom. A protective cover and a debris absorber are respectively mounted on the bottom of the two electric push rods. The protective cover can be lowered to engage with the square frame, and an electric polishing head is installed inside the protective cover. The long shaft rotates on the device platform and is connected to a motor at the bottom.

[0007] Two notched platforms are parallel to each other but misaligned at both ends. The two notched platforms are connected to a long axis by a moving drive assembly. The moving drive assembly drives the two notched platforms to move synchronously by a certain distance when the long axis rotates.

[0008] Furthermore, each side of the bottom of the square plate has a row of ball grooves arranged in an arc shape, with balls rolled inside the grooves. The balls slide on the top of the annular slide, which is fixed to the top of the device platform by four support rods.

[0009] Furthermore, the moving drive assembly includes a large gear rotatably mounted on the bottom of the device platform. The large gear is meshed with a toothed track and a small gear. The small gear is fixedly sleeved on the outside of the long shaft and located below the device platform. The toothed track is set on one side of the long plate, and the side wall of the long plate is connected to another long plate without a toothed track by two steel plates. The top of the long plate is connected to the bottom of the recessed platform by two protrusions, and the protrusions slide in the opening of the device platform.

[0010] Furthermore, the long plate is slidably connected by two long rods passing through it, and the long rods are fixed to the inside of the platform of the device.

[0011] Furthermore, a row of rollers is rotatably installed on both sides of the notched platform, and the rollers roll on the surface of the device platform.

[0012] Furthermore, a positioning component is installed on one side of the frame, including a U-shaped frame fixed to one side of the frame. The U-shaped frame is rotatably mounted with a screw rod on the frame. A U-shaped block is threaded onto the screw rod. The U-shaped block slides through the opening of the frame, and a pressure plate is fixed to the inner end of the U-shaped block within the frame.

[0013] Furthermore, one side of the recessed platform is designed with an opening, and a collection box is inserted into the opening. A U-shaped plate is engaged at one end and both sides of the recessed platform. The U-shaped plate is engaged with the end face of the collection box, and the two sides of the U-shaped plate are inserted into the slots on both sides of the recessed platform. An extension plate is fixed to the top of the U-shaped plate, and a retaining plate is engaged in the recess at the top corner of the extension plate. The retaining plate is fixed to the bottom of the U-shaped block, and the bottom surface of the retaining plate is higher than the top surface of the collection box.

[0014] Compared with related technologies, the polishing device for reamer bolt holes provided by this utility model has the following advantages:

[0015] This invention uses a moving drive component to drive two concave stages to work alternately, achieving continuous polishing at two stations and avoiding the efficiency bottleneck of traditional single-station processing. At the same time, the automated feeding design reduces manual intervention, which not only improves processing accuracy but also eliminates the safety hazards of manual feeding. The sealed fit between the protective cover and the frame confines the debris within the enclosed space.

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

[0027] Depend on Figures 1-8This invention provides a polishing device for reamer bolt holes, comprising a device platform 1. Two recessed platforms 11 are linearly mounted on the top of the device platform 1. A square frame 12 is fixedly mounted on the top of the recessed platforms 11. Two support plates 13 are fixed to the inner wall of the square frame 12. A polishing assembly 2 is mounted on the device platform 1. The polishing assembly 2 includes a square plate 23 rotatably mounted on the top of the device platform 1. Electric push rods 24 are mounted at both ends of the bottom of the square plate 23, and a long shaft 22 is mounted at the middle of the bottom. A protective cover 26 and a debris absorber 25 are respectively mounted on the bottom of the two electric push rods 24. The protective cover 26 can be lowered to engage with the square frame 12, and an electric polishing head 27 is installed inside the protective cover 26. The long shaft 22 rotates on the device platform 1 and is connected to a motor 21 at its bottom. Two recessed platforms 11 are parallel to each other but misaligned at both ends. The two recessed platforms 11 are connected to a long shaft 22 by a moving drive assembly 4. When the long shaft 22 rotates, the moving drive assembly 4 drives the two recessed platforms 11 to move synchronously by a certain distance. The moving drive assembly 4 includes a large gear 42 rotatably installed at the bottom of the device platform 1. The large gear 42 is respectively meshed with a toothed track 43 and a small gear 41. The small gear 41 is fixedly sleeved on the outside of the long shaft 22 and located below the device platform 1. The toothed track 43 is set on one side of the long plate 44, and the side wall of the long plate 44 is connected to another long plate 44 without a toothed track 43 by two steel plates 45. The top of the long plate 44 is connected to the bottom of the recessed platform 11 by two protrusions, and the protrusions slide in the opening of the device platform 1.

[0028] As described above, through the design of the moving drive component 4 and the grinding component 2, during processing, two metal plates that have already had bolt holes machined by a reamer are placed in the frame 12. The three outer walls of the plates are attached to the inner wall of the frame 12 and placed on the support plate 13. This can be achieved by setting a rubber sealing gasket on the inner wall of the frame 12. Then, the last side is fixed by the existing push clamping structure, with the drilled surface facing upwards. The surface of these holes may have burrs. Afterwards, the electric push rod 24 is activated to lower the protective cover 26 and the debris absorber 25 to the appropriate position. The protective cover 26 can be lowered to engage with a... The frame 12 engages, specifically with the frame 12 closer to the cover 26. A sealing gasket can be placed on the engaging surface of the cover 26. The bottom surface of the cover 26 also contacts the surface of the board. The board is designed so that its surface aligns with the surface of the frame 12 after placement. The electric polishing head 27, installed inside the cover 26, also contacts the hole. At this point, the electric polishing head 27 is activated for polishing, trapping debris within the cover 26. After completion, the electric polishing head 27 and the debris absorber 25 are raised. The debris absorber 25 does not activate during the initial polishing. Subsequently, the motor 21 is activated, driving the long shaft 22 and the square plate 23 to rotate. At 180 degrees, the long shaft 22 drives the large gear 42 to rotate via the small gear 41. The large gear 42 meshes with the toothed track 43, causing the long plate 44 to slide along the long rod 46, thereby driving the two recessed platforms 11 to move synchronously by a certain distance. At this time, the first bolt hole of the plate at the top of the rear frame 12 corresponds to the position of the polishing head after rotation. The previous operation is repeated for polishing. Meanwhile, the debris absorber 25 descends above the other frame 12. The debris absorber 25 is then activated to absorb the debris remaining from the previous polishing. At the same time, the electric polishing head 27 polishes the bolt hole of the second plate. This process is repeated. This enables continuous feeding polishing at dual stations. Each time the long shaft 22 and the square plate 23 rotate 180 degrees, the next bolt hole is brought to the polishing position. It also enables precise and efficient collection and processing of debris. After the work is completed, the inside of the debris absorber 25 is cleaned. The motor 21 drives the long shaft 22 to rotate in the opposite direction to reset the two recessed platforms 11 for unloading. The debris absorber 25 is a suction-type structure design. Both the electric polishing head 27 and the debris absorber 25 are existing technologies. The debris absorber 25 does not contact the square frame 12 and does not need to be located directly above the polishing hole. It can absorb debris from all directions when it is within a suitable range.

[0029] A row of ball bearing grooves is distributed in an arc shape on the bottom of both sides of the square plate 23. Ball bearings 29 are rolled in the grooves and slide on the top of the annular slide 28. The annular slide 28 is fixed to the top of the device platform 1 by four support rods. The long plate 44 is slidably connected by two long rods 46 passing through it. The long rods 46 are fixed to the inside of the platform 1. A row of rollers 15 is rotatably installed on both sides of the recessed platform 11 and rolls on the surface of the device platform 1.

[0030] Furthermore, when the square plate 23 rotates, the ball bearing 29 slides on the top of the shaped slide rail 28, the long plate 44 slides outside the long rod 46, and when the notched platform 11 moves, the roller 15 rolls on the surface of the device platform 1. These designs all improve the stability of the equipment during operation and are very practical.

[0031] A positioning component 3 is installed on one side of the frame 12, including a U-shaped frame 31 fixed to one side of the frame 12. A screw rod 32 is rotatably installed on the U-shaped frame 31 and the frame 12. A U-shaped block 33 is threadedly connected to the screw rod 32. The U-shaped block 33 slides through the opening of the frame 12. A pressure plate 34 is fixed at the inner end of the U-shaped block 33 in the frame 12. The recessed platform 11 has an opening on one side, and a collection box 14 is inserted into the opening. A U-shaped plate 37 is engaged at one end and both sides of the recessed platform 11. The U-shaped plate 37 is engaged with the end face of the collection box 14 and the recessed platform 11. The two sides of the U-shaped plate 37 are inserted into the slots 38 on both sides of the recessed platform 11. An extension plate 36 is fixed to the top of the U-shaped plate 37. A retaining plate 35 is engaged in the notch at the top corner of the extension plate 36. The retaining plate 35 is fixed to the bottom of the U-shaped block 33, and the bottom surface of the retaining plate 35 is higher than the top surface of the collection box 14. The inside of the collection box 14 can also be designed with some conventional debris adsorption structures.

[0032] Finally, in terms of positioning optimization design, one end of the plate does not contact the frame 12 after placement, making it convenient to remove the plate after the work is completed. During positioning, rotating the screw 32 causes the U-shaped block 33 to slide along the opening of the frame 12, so that the pressure plate 34 moves towards the plate and presses the end of the plate that does not contact the frame 12. At the same time, if the bolt hole is a through hole design, some debris will enter the recessed platform 11 during polishing. Beforehand, the collection box 14 is inserted into the recessed platform 11, and then the slot 38 is inserted into the U-shaped plate 37 for limiting. Since the clamping plate 35 is fixed at the bottom of the U-shaped block 33, the clamping plate 35 moves synchronously with the U-shaped block 33 during the positioning operation. After the fixing is completed, the clamping plate 35 can be locked onto the upper end of the extension plate 36 after positioning, and the extension plate 36 cannot move horizontally, ensuring that the collection box 14 is stably attached to the recessed platform 11.

[0033] Working principle: Two workpieces are placed in the square frame of the recessed platform and positioned by the pressure plate. During processing, the protective cover descends and engages with the square frame to form a closed chamber. The electric polishing head grinds the bolt holes and temporarily stores the debris. Then, the motor drives the long shaft to rotate 180°, and at the same time, the two recessed platforms are synchronously moved through the gear tooth transmission, so that the workpiece behind is aligned with the polishing head. At the same time, the debris absorber descends above the original station to clean up the residual debris, and polishing starts at the new station simultaneously, realizing parallel processing and cleaning. After processing is completed, the motor resets the recessed platform, and the protective cover and absorber return to their positions, completing the dual-station alternating operation and zero debris leakage collection, significantly improving efficiency and cleanliness.
