Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a double-beam polishing machine. Background Art

[0002] A polishing machine is an electric tool. It consists of basic components such as a base, a polishing disc, a polishing fabric, a polishing hood and a cover. The motor is fixed on the base, and the cone sleeve for fixing the polishing disc is connected to the motor shaft through a screw. The polishing fabric is fastened to the polishing disc through a ferrule. After the motor is powered on by the switch on the base, pressure can be applied to the sample by hand to polish it on the rotating polishing disc. The polishing liquid added during the polishing process can flow into the square plate placed next to the polishing machine through the drain pipe in the plastic plate fixed on the base. The polishing hood and cover can prevent dust and other debris from falling on the polishing fabric when the machine is not in use, thereby affecting the use effect. It is widely used in industrial production.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 8 , the present invention provides a technical solution:

[0031] The fixing mechanism 4 includes a left cross frame 41, a connecting rod 42, a spring 43, and a stop plate 44. The left cross frame 41 is embedded and fixedly connected to a position near the middle of the left support frame 2. The connecting rod 42 is movably connected to the inside of the left cross frame 41. The left end of the inner surface of the left cross frame 41 is fixedly connected to a spring 43. The other end of the spring 43 is fixedly connected to the left end of the inner surface of the left cross frame 41. The right end of the connecting rod 42 is rotatably connected to the stop plate 44 through a bearing.

[0032] By adopting the above technical solution, when in use, the plate 44 is moved to the left, driving the connecting rod 42 to squeeze the spring 43, so that the bottom end of the cup-shaped metal part is pressed against the right outer surface of the plate 44. Under the action of the elastic force of the spring 43, the plate 44 is driven to the right to resist the contact between the metal part and the drive component 5, and the metal part is clamped together, which effectively avoids manual support of the metal part for processing and greatly reduces the labor intensity of the staff. In conjunction with the drive component 5 and the polishing component 6, the inner surface of the metal part can be automatically polished, which not only has a good polishing effect, but also greatly improves the work efficiency and has strong overall practicality.

[0033] As an embodiment of the present invention, Figure 3 As shown, the driving assembly 5 includes a right cross frame 51, a sleeve 52, a telescopic rod 53, a gear 54, a motor 55, a gear 56, a chain 57, and a sealing plate 58. The right cross frame 51 is embedded and fixedly connected to the position corresponding to the fixing mechanism 4 inside the right support frame 3. The sleeve 52 is rotatably connected to the position near the right side of the right cross frame 51 through a bearing. The telescopic rod 53 is threadedly connected to the inside of the sleeve 52, and the left half of the telescopic rod 53 is designed as a square structure and matches the right cross frame 51. The sleeve 52 is connected to the right side of the right cross frame 51 through a bearing. 2 is fixedly connected to a gear 1 54 on the outer surface of the right end, and the gear 1 54 extends to the outside of the right cross frame 51. A motor 1 55 is fixedly connected to the outer surface of the upper end of the right cross frame 51 near the right side of the right support frame 3. The motor 1 55 is a double-axis motor, and a gear 2 56 is fixedly connected to the top of the right end output shaft thereof. A chain 1 57 is meshed with the gear 1 54, and the chain 1 57 and the gear 1 54 are meshed with each other. A sealing plate 58 is provided on the outer surface of the right cross frame 51 near the left side of the right support frame 3, and the sealing plate 58 is rotatably connected to the right support frame 3.

[0034] By adopting the above technical scheme, when working, the cup mouth of the metal part is matched with the sealing plate 58 to seal the cup mouth of the metal part, which can ensure that the metal dust generated inside the metal part will not be scattered to the outside to cause harm to the human body during processing, and under the resistance of the plate 44, the metal part can be clamped and fixed together without manual clamping, saving a lot of manpower. The motor 55 is started to drive the gear 2 56 to rotate, and the gear 1 54 is driven to rotate through the chain 1 57, thereby driving the sleeve 1 52 to rotate. Since the sleeve 1 52 is threadedly connected with the telescopic rod 1 53, the telescopic rod 1 53 is driven to move to the left, and then the polishing assembly 6 is driven to move to the left to polish the inner surface of the metal part evenly and effectively, which greatly improves the processing efficiency. The motor 1 55 is controlled to rotate forward and reverse, which can drive the polishing assembly 6 to polish back and forth, ensuring the integrity of the polishing.

[0035] As an embodiment of the present invention, Figure 5As shown, the sealing plate 58 is made of a transparent material, and a rubber sheet 7 is fixedly connected to its left outer surface. The left outer surface of the rubber sheet 7 is provided with a plurality of groups of annular grooves 8 at equal distances with the center of the right cross frame 51 as the midpoint.

[0036] By adopting the above technical solution, the sealing plate 58 is made of transparent material, which ensures that during the processing, the user can monitor the polishing condition inside the metal part at any time, so as to make timely adjustments according to the situation. The rubber sheet 7 is fixedly connected to greatly improve the friction between the sealing plate 58 and the metal part, effectively reducing the occurrence of slipping during the polishing process, ensuring the stability of the polishing process, and providing several groups of annular grooves 8 to more accurately position cup-shaped metal parts of different sizes, greatly facilitating the clamping and fixation of the metal parts.

[0037] As an embodiment of the present invention, Figure 3 and Figure 4 As shown, the right outer surface of the sealing plate 58 is fixedly connected with the inner gear ring 11, the left output shaft of the motor 55 passes through the right support frame 3, and the top end of the left output shaft is fixedly connected with the gear 5 12, and the gear 5 12 is meshed with the inner gear ring 11.

[0038] By adopting the above technical solution, when the motor 1 55 rotates, the gear 5 12 is driven to rotate through the left output shaft. Since the gear 5 12 and the inner gear ring 11 are meshed with each other, the inner gear ring 11 is driven to rotate, thereby driving the sealing plate 58 to rotate at a uniform speed, and then driving the metal parts clamped by it to rotate at a uniform speed. With the use of the polishing component 6, the circumferential inner surface of the metal part can be evenly polished, ensuring the integrity of the polishing.

[0039] As an embodiment of the present invention, Figure 6 and Figure 7As shown, the polishing assembly 6 includes a fixed cylinder 61, a sleeve 62, a telescopic rod 63, a rotating wheel 64, a motor 65, a gear 3 66, a rotating shaft 67, a polishing roller 68, a gear 4 69, a chain 2 610, and a slide rail 611. The left outer surface of the telescopic rod 1 53 is fixedly connected with the fixed cylinder 61, and the inner part of the fixed cylinder 61 near the bottom end is rotatably connected with the sleeve 2 62 through a bearing. The inner part of the sleeve 2 62 is threadedly connected with the telescopic rod 2 63. A cavity is provided in the inner part of the telescopic rod 2 63 near the upper end, and the upper half of the telescopic rod 2 63 is designed as a square structure and matches the fixed cylinder 61. The outer surface of the bottom end of the sleeve 2 62 is fixedly connected with the rotating wheel 64, and the rotating wheel 64 extends to the outside of the fixed cylinder 61. The telescopic rod 2 63 A motor 2 65 is fixedly connected to a position near the middle of the left outer surface, and the output shaft of the motor 2 65 extends to the inside of the cavity of the telescopic rod 2 63, and a gear 3 66 is fixedly connected to the top of the output shaft of the motor 2 65. A rotating shaft 67 is rotatably connected to the telescopic rod 2 63 near the top through a bearing embedded therein, and polishing rollers 68 are symmetrically fixedly connected to the annular outer surface of the rotating shaft 67 near the left and right sides of the telescopic rod 2 63, and a gear 4 69 is fixedly connected to the annular outer surface of the rotating shaft 67 at a position located inside the cavity of the telescopic rod 2 63, a chain 2 610 is meshedly connected to the gear 4 69, and the chain 2 610 is meshedly connected to the gear 3 66, and slide rails 611 are symmetrically fixedly connected to the outer surfaces of the front and rear ends of the telescopic rod 2 63 near the lower end of the polishing roller 68.

[0040] By adopting the above technical solution, when working, the inner diameter of the metal part is measured, and the rotating wheel 64 is rotated to drive the sleeve 2 62 to rotate. Since the sleeve 2 62 is threadedly connected to the telescopic rod 2 63, the telescopic rod 2 63 is driven to move upward or downward, and then the position of the polishing roller 68 fixedly connected thereto can be adjusted, so that metal parts of different sizes can be polished. The overall practicality is strong and the application range is wide. After adjusting to a suitable position, the motor 2 65 is started to drive the gear 3 66 to rotate, thereby driving the gear 4 69 to rotate through the chain 2 610, and then driving the rotating shaft 67 to rotate, and the polishing roller 68 rotates accordingly, and the inner surface of the metal part is evenly polished.

[0041] As an embodiment of the present invention, Figure 7 and Figure 8 As shown, the outer surface of the slide rail 611 is slidably connected with a dust cover 9, the dust cover 9 is designed as an arc-shaped structure, and a magnet sheet 10 is slidably connected inside the dust cover 9.

[0042] By adopting the above technical solution, during operation, a large amount of metal debris generated during the polishing process can be adsorbed by the magnet sheet 10 and collected on the outer surface of the dust cover 9, effectively reducing the probability of metal dust spreading around. When the processing is completed, the dust cover 9 is removed along the slide rail 611, and the magnet sheet 10 is pulled out to easily pour out the metal debris adsorbed on the outer surface of the dust cover 9 for disposal, which not only reduces the labor intensity of the staff, but also ensures the health of the staff.

[0043] Working principle: When working, measure the inner diameter of the metal part, rotate the rotating wheel 64, and drive the sleeve 62 to rotate. Since the sleeve 62 is threadedly connected to the telescopic rod 63, the telescopic rod 63 is driven to move upward or downward, and then the position of the polishing roller 68 fixedly connected thereto can be adjusted, so that metal parts of different sizes can be polished. When in use, move the plate 44 to the left, drive the connecting rod 42 to squeeze the spring 43, and make the bottom end of the cup-shaped metal part press against the right outer surface of the plate 44. Under the action of the elastic force of the spring 43, drive the plate 44 to resist the metal part to the right, so that the cup mouth of the metal part is aligned with the annular groove 8 on the sealing plate 58. Matching each other, the metal cup mouth is sealed, which can ensure that the metal dust generated inside will not be spread to the outside world and cause harm to the human body during processing, and under the resistance of the plate 44, the metal part can be clamped and fixed together without manual clamping, saving a lot of manpower, and clamping the metal part together, effectively avoiding manual support of the metal part for processing, greatly reducing the labor intensity of the staff, starting the motor 2 65, driving the gear 3 66 to rotate, thereby driving the gear 4 69 to rotate through the chain 2 610, and then driving the shaft 67 to rotate, and the polishing roller 68 rotates accordingly, and the inner surface of the metal part is evenly polished, and the motor 1 55 is started, The gear 2 56 is driven to rotate, and the gear 1 54 is driven to rotate through the chain 1 57, thereby driving the sleeve 1 52 to rotate. Since the sleeve 1 52 is threadedly connected with the telescopic rod 1 53, the telescopic rod 1 53 is driven to move to the left, and then the polishing assembly 6 is driven to move to the left to polish the inner surface of the metal part evenly and effectively, which greatly improves the processing efficiency. The motor 1 55 is controlled to rotate forward and reverse, which can drive the polishing assembly 6 to polish back and forth. When the motor 1 55 rotates, the gear 5 12 is driven to rotate through the left output shaft. Since the gear 5 12 and the inner gear ring 11 are meshed with each other, the inner gear ring 11 is driven to rotate, thereby driving the sealing plate 58 to rotate at a uniform speed. , thereby driving the metal part clamped and fixed by it to rotate at a uniform speed. With the use of the polishing component 6, the circumferential inner surface of the metal part can be evenly polished, ensuring the integrity of the polishing. A large amount of metal debris generated during the polishing process can be adsorbed by the magnet sheet 10 and collected on the outer surface of the dust cover 9, effectively reducing the probability of metal dust spreading around. When the processing is completed, the dust cover 9 is removed along the slide rail 611, and the magnet sheet 10 is pulled out to easily pour out the metal debris adsorbed on the outer surface of the dust cover 9 for disposal, which not only reduces the labor intensity of the staff, but also ensures the health of the staff. The overall structure is simple and practical.
