Description

Technical Field

[0001] The invention relates to the technical field of grinding, and in particular to a grinding device for manufacturing metal parts. Background Art

[0002] Surface grinding equipment is a mechanical device used for grinding, polishing, deburring and other processes on the surface of processed parts. Lost foam casting is a casting technology commonly used in the metal casting process. After the parts made by lost foam are formed, they need to be ground and polished. When grinding the surface of parts, a vibration polishing machine is often used to grind the parts. The vibration polishing machine places the parts into a grinding cylinder filled with polishing sand, and through vibration, the parts and the polishing sand are fully in contact and move relative to each other, so as to remove burrs, oxide layers, and welds on the surface of the casting, thereby achieving polishing and grinding to improve the surface quality and precision of the product.

[0003] In order to prevent parts from colliding and crossing each other during the polishing process, the prior art adopts the method of fixing the parts on a fixture before polishing to avoid collision between parts. However, due to the restrictions of the fixture on the parts, the movement space of the parts during the polishing process is relatively limited, making it difficult to completely polish the holes, grooves and other special-shaped structures of the parts themselves, affecting the polishing effect.

The limit compression spring and the limit hole cooperate to straighten the connecting column on the side of the limit plate close to the slider radially along the mounting rod, and when the connecting column slides out of the limit hole in the direction away from the mounting rod, the limit of the limit hole is lost, and the ball joint between the connecting columns is used to achieve the parts on the connecting plate to shake freely with the vibration of the polishing sand in the grinding cylinder, thereby increasing the range of motion of the parts, so that each position of the parts can fully contact and be polished with the polishing sand.

[0008] Furthermore, the driving assembly includes a driving cylinder, a matching cylinder, and a driving plate; the driving cylinder is coaxially sleeved on the outside of the mounting rod; the driving cylinder is arranged between the sliding disk and the rotating cylinder; one end of the driving cylinder close to the rotating cylinder is fixedly connected to the rotating cylinder; a spiral groove is provided on the outer wall of the driving cylinder; the matching cylinder is arranged between the sliding disk and the rotating cylinder; the matching cylinder is coaxially sleeved on the driving cylinder, and one end of the matching cylinder close to the sliding disk is rotationally matched with the sliding disk, and a driving ring is coaxially fixed on the end close to the rotating cylinder; a swivel is rotatably installed on the side of the driving ring close to the rotating cylinder; a return spring is provided between the swivel and the rotating cylinder; one end of the return spring is fixedly connected to the swivel, and the other end is fixedly connected to the rotating cylinder; a sliding bulge is provided on the inner wall of the matching cylinder; the sliding bulge and the spiral groove are slidably matched; a plurality of driving plates are evenly distributed along the circumferential direction of the vertical axis; the driving plate is arranged on the lower side of the driving ring; the driving plate is fixed at the lower end of the vertical shaft; the upper end surface of the driving plate is meshed with the outer wall of the driving ring. When the upper end surface of the driving plate and the outer wall of the driving ring are in contact, the driving plate drives the driving ring to rotate, and the driving ring drives the matching cylinder to rotate, and the matching cylinder drives the sliding protrusion to slide in the spiral groove, so as to drive the matching cylinder to push the sliding plate away from the vertical axis and stretch the reset spring to store force. When the upper end surface of the driving plate and the outer wall of the driving ring are out of contact, the reset spring releases the force and drives the matching cylinder to approach the vertical axis through the driving ring, thereby driving the sliding plate to periodically move away from and close to the vertical axis.

[0009] Furthermore, the auxiliary component includes an auxiliary disk; the auxiliary disk is arranged on the side of the sliding disk away from the vertical axis; the auxiliary disk is coaxially fixed on the mounting rod; a plurality of auxiliary plates are arranged on the auxiliary disk; the plurality of auxiliary plates are evenly distributed along the circumference of the auxiliary disk; the auxiliary plate is arranged obliquely along the axis of the mounting rod on the side of the auxiliary disk away from the vertical axis; the distance from the end of the auxiliary plate close to the vertical axis to the mounting rod is smaller than the distance from the end of the auxiliary plate close to the vertical axis to the mounting rod; the end of the auxiliary plate close to the vertical axis is rotatably mounted on the auxiliary disk; the lower end surface of the slider is arc-shaped; the auxiliary plate and the lower end surface of the slider are in contact; an adjustment structure is arranged at the end of the auxiliary plate away from the vertical axis; the adjustment structure is used to adjust the angle between the auxiliary plate and the axis of the mounting rod. Adjustment is performed according to the characteristics of the part itself. When the mass of the part is large, the angle between the auxiliary plate and the axis of the mounting rod is reduced, so that when the sliding disk moves a certain distance away from the vertical axis, the distance of the slider away from the axis of the mounting rod is reduced, thereby reducing the range of movement of the part and avoiding damage to the parts and equipment caused by the large inertia caused by the large mass.

[0010] In the process of the power assembly driving the rotating drum to revolve around the vertical axis, when the upper end surface of the driving plate abuts against the outer side wall of the driving ring, the driving plate drives the driving ring to rotate, the driving ring drives the matching cylinder to rotate, and the matching cylinder drives the sliding protrusion to slide in the spiral groove to drive the matching cylinder to push the sliding plate away from the vertical axis and stretch the reset spring to store force. The sliding plate drives the slider away from the vertical axis. Driven by the inclined auxiliary plate, the slider moves away from the axis of the mounting rod along the radial direction of the sliding plate. The slider pushes the connecting column away from the mounting rod, overcomes the tension of the limiting compression spring and stretches the limiting compression spring. When the connecting column slides out of the limiting hole in the direction away from the mounting rod, the limiting hole loses its limit, and the ball joint between the connecting columns enables the parts on the connecting plate to shake freely with the vibration of the polishing sand in the grinding cylinder, thereby increasing the range of motion of the parts, so that each position of the parts can be fully contacted with the polishing sand and polished.

[0011] When the upper end surface of the driving plate and the outer wall of the driving ring are out of contact, the reset spring releases force and drives the matching cylinder to approach the vertical axis through the driving ring, thereby driving the sliding plate to periodically move away from and approach the vertical axis. The sliding plate drives the slider to approach the vertical axis to reset. During this process, the limit compression spring pulls the connecting plate to drive the parts to approach the mounting rod.

[0012] Furthermore, the adjustment structure includes an adjustment ring and an adjustment disk; the adjustment ring and the mounting rod are threadedly matched; the adjustment disk is coaxially sleeved on the mounting rod and is rotationally matched with the adjustment ring; an adjustment rod is provided between the adjustment disk and the auxiliary plate; one end of the adjustment rod is hinged to the auxiliary plate, and the other end is hinged to the adjustment disk. When it is necessary to adjust the angle between the auxiliary plate and the axis of the mounting rod, the adjustment ring is rotated to drive the adjustment disk to move along the mounting rod, and the angle between the auxiliary plate and the mounting rod is adjusted by the adjustment rod. When the mass of the part is large and the angle between the auxiliary plate and the mounting rod needs to be reduced, the adjustment ring is driven to drive the adjustment disk to move away from the auxiliary disk.

The combination of the action of the sliding plate driving the parts to rotate around the axis of the mounting rod and the action of the driving assembly driving the sliding plate to drive the parts to slide along the axis of the mounting rod makes the grinding of the parts on the connecting plate more uniform.

[0014] Furthermore, the self-rotating assembly includes a self-rotating groove and a self-rotating wheel; the self-rotating groove is an annular groove, which is arranged on the side wall at the lower end of the vertical shaft; the self-rotating wheel is arranged in the self-rotating groove; the self-rotating wheel is coaxially fixed to one end of the mounting rod close to the vertical shaft; the self-rotating wheel and the lower groove wall of the self-rotating groove are meshed and matched.

[0016] Furthermore, the power assembly includes a power motor; the power motor is fixed on the moving plate; and the output shaft of the power motor and the rotating drum are driven by gear meshing.

[0017] Furthermore, the clamping structure is arranged on the end face of the connecting plate away from the mounting rod; the clamping structure includes a fixed plate and a movable plate; the fixed plate is fixed on the connecting plate, and the movable plate slides on the connecting plate; a bolt is arranged between the movable plate and the connecting plate; the bolt is rotatably connected to the movable plate and is threadedly connected to the connecting plate.

[0043] In the process of the power component 230 driving the rotating drum 310 to revolve around the axis of the vertical shaft 300, when the upper end surface of the driving plate 740 abuts against the outer wall of the driving ring 730, the driving plate 740 drives the driving ring 730 to rotate, and the driving ring 730 drives the matching cylinder 720 to rotate, and the matching cylinder 720 drives the sliding protrusion to slide in the spiral groove 711, so as to drive the matching cylinder 720 to push the sliding disk 500 away from the axis of the vertical shaft 300, and stretch the reset spring 731 to store force. The sliding plate 500 drives the slider 620 away from the vertical axis 300. Driven by the inclined auxiliary plate 820, the slider 620 moves radially away from the axis of the mounting rod 400 along the sliding plate 500. The slider 620 pushes the connecting column 640 away from the mounting rod 400, overcomes the tension of the limiting compression spring 651 and stretches the limiting compression spring 651. When the connecting column 640 slides out of the limiting hole 652 in the direction away from the mounting rod 400, the limiting hole 652 loses its limit. Through the ball joint between the connecting columns 640, the parts on the connecting plate 630 can shake freely with the vibration of the polishing sand in the polishing cylinder 200, thereby increasing the range of motion of the parts so that each position of the parts can fully contact and be polished with the polishing sand.

[0044] When the upper end surface of the driving plate 740 and the outer wall of the driving ring 730 are out of contact, the reset spring 731 releases force and drives the matching cylinder 720 to approach the axis of the vertical shaft 300 through the driving ring 730, thereby driving the sliding plate 500 to periodically move away from and approach the axis of the vertical shaft 300. The sliding plate 500 drives the slider 620 to approach the vertical shaft 300 to reset. During this process, the limiting compression spring 651 pulls the connecting plate 630 to drive the parts to approach the mounting rod 400. The limiting compression spring 651 and the limiting hole 652 cooperate to make the connecting column 640 on the side of the limiting plate 610 close to the slider 620 straighten along the radial direction of the mounting rod 400.

[0045] In this embodiment, the lifting assembly includes a lifting hydraulic cylinder; a movable plate 220 is fixed on the piston rod of the lifting hydraulic cylinder; the movable plate 220 is arranged above the grinding cylinder 200; and the upper end of the vertical shaft 300 is fixed on the movable plate 220. The power assembly 230 includes a power motor; the power motor is fixed on the movable plate 220; the output shaft of the power motor and the rotating cylinder 310 are driven by gear meshing. The clamping structure is arranged on the end surface of the connecting plate 630 away from the mounting rod 400; the clamping structure includes a fixed plate 661 and a movable plate 662; the fixed plate 661 is fixed on the connecting plate 630, and the movable plate 662 slides on the connecting plate 630; bolts are arranged between the movable plate 662 and the connecting plate 630; the bolts are rotatably connected to the movable plate 662 and are threadedly connected to the connecting plate 630.

[0046] In combination with the above embodiments, the use principle and working process of the present invention are as follows: when in use, the parts are adjusted according to their own characteristics. When the angle between the auxiliary plate 820 and the axis of the mounting rod 400 needs to be adjusted, the adjusting ring 831 is rotated to drive the adjusting disk 832 to move along the mounting rod 400, and the angle between the auxiliary plate 820 and the mounting rod 400 is adjusted by the adjusting rod 833. When the weight of the parts is large and the angle between the auxiliary plate 820 and the mounting rod 400 needs to be reduced, the adjusting ring 831 is driven to drive the adjusting disk 832 to move away from the auxiliary plate 810, and the angle between the auxiliary plate 820 and the axis of the mounting rod 400 is reduced, so that when the sliding plate 500 moves a certain distance away from the vertical axis 300, the distance between the slider 620 and the axis of the mounting rod 400 is reduced, thereby reducing the range of movement of the parts and avoiding the damage of the parts and equipment caused by the large inertia caused by the large weight.

[0047] Then the parts are fixed on the connecting plate 630 through the clamping structure. The lifting hydraulic cylinder drives the vertical shaft 300 to drive the grinding device to move down and contact the polishing sand, starts the power motor, and drives the rotating drum 310 to rotate. During the process of the rotating drum 310 revolving around the axis of the vertical shaft 300, when the upper end surface of the driving plate 740 abuts against the outer side wall of the driving ring 730, the driving plate 740 drives the driving ring 730 to rotate, and the driving ring 730 drives the matching cylinder 720 to rotate, and the matching cylinder 720 drives the sliding protrusion to slide in the spiral groove 711, so as to drive the matching cylinder 720 to push the sliding plate 500 away from the axis of the vertical shaft 300, and stretch the reset spring 731 to store force. The sliding plate 500 drives the slider 620 away from the vertical axis 300. Driven by the inclined auxiliary plate 820, the slider 620 moves radially away from the axis of the mounting rod 400 along the sliding plate 500. The slider 620 pushes the connecting column 640 away from the mounting rod 400, overcomes the tension of the limiting compression spring 651 and stretches the limiting compression spring 651. When the connecting column 640 slides out of the limiting hole 652 in the direction away from the mounting rod 400, the limiting hole 652 loses its limit. Through the ball joint between the connecting columns 640, the parts on the connecting plate 630 can shake freely with the vibration of the polishing sand in the polishing cylinder 200, thereby increasing the range of motion of the parts so that each position of the parts can fully contact and be polished with the polishing sand.

[0048] When the upper end surface of the driving plate 740 and the outer wall of the driving ring 730 are out of contact, the reset spring 731 releases force and drives the matching cylinder 720 to approach the axis of the vertical shaft 300 through the driving ring 730, thereby driving the sliding plate 500 to periodically move away from and approach the axis of the vertical shaft 300. The sliding plate 500 drives the slider 620 to approach the vertical shaft 300 to reset. During this process, the limiting compression spring 651 pulls the connecting plate 630 to drive the parts to approach the mounting rod 400. The limiting compression spring 651 and the limiting hole 652 cooperate to make the connecting column 640 on the side of the limiting plate 610 close to the slider 620 straighten along the radial direction of the mounting rod 400.

[0049] When the rotating drum 310 drives the mounting rod 400 to revolve around the axis of the vertical shaft 300, the rotating wheel 920 and the lower groove wall of the rotating groove 910 engage with each other, so that the rotating wheel 920 drives the mounting rod 400 to rotate around its own axis, and the mounting rod 400 drives the sliding plate 500 to rotate around the axis of the mounting rod 400, so that the sliding plate 500 drives the parts to rotate around the axis of the mounting rod 400 through the clamping assembly and the driving assembly drives the sliding plate 500 to drive the parts to slide along the axis of the mounting rod 400, so that the grinding of the parts on the connecting plate 630 is more uniform.
