Detailed Description

The technical solutions in the implementation of the present invention will be made clear and fully described below with reference to the accompanying drawings, and the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 5, an inner wall polishing device for a multi-bend tubular casting according to an embodiment of the present invention includes a polishing assembly 1 and an advancing assembly 2 for advancing the polishing assembly 1 to move in an inner cavity of the multi-bend tubular casting, wherein the advancing assembly 2 can be manually pushed into the interior of the multi-bend tubular casting, so that the advancing assembly 2 can advance the polishing assembly 1 to move. The polishing assembly 1 comprises a motor 11, a positioning assembly 15, a transmission assembly 16 and a polishing head 14, a positioning ring 12 is fixedly connected to the output end of the motor 11, a rotating ring 13 with the same axis is rotatably mounted on the positioning ring 12, and the polishing head 14 is mounted on the rotating ring 13, so that when the rotating ring 13 rotates, the polishing head 14 rotates together, the contact position of the polishing head 14 and the inner wall of the tubular casting is changed, polishing at different positions is realized, and when workers push the polishing head 14 to move in the tubular casting by using the pushing assembly 2, gradual polishing of the inner wall of the tubular casting can be realized.

The positioning assembly 15 includes at least three groups of positioning units uniformly distributed on the positioning ring 12, each positioning unit includes two second cylinders 151 respectively fixed on two sides of the positioning ring 12, the output ends of the two second cylinders 151 on the same positioning unit are connected through a limiting rod 153, and the output end of each second cylinder 151 is provided with a positioning roller 152. As can be seen from fig. 1, 2 and 4, because the limiting rod 153 is provided, the two second cylinders 151 on the same positioning unit can only extend and retract together, and meanwhile, the limiting rod 153 bypasses from the inner side of the positioning ring 12, so that the limiting rod 153 does not affect the normal operation of the sanding head 14. The sanding head 14 includes a first cylinder 141 vertically mounted on the side wall of the swivel 13 and a sanding wheel 142 rotatably mounted on the output bracket of the first cylinder 141. When all the second cylinders 151 are operated simultaneously, the two positioning rollers 152 of each positioning unit can be in contact with the inner wall of the tubular casting, so that the positioning ring 12 between the two positioning rollers 152 is kept perpendicular to the inner wall of the tubular casting, thereby keeping the sanding head 14 perpendicular to the inner wall of the tubular casting. When the motor 11 drives the polishing head 14 to polish the inner wall of the tubular casting through the transmission assembly 16, because the positioning assembly 15 can enable the polishing head 14 to be kept perpendicular to the inner wall of the tubular casting, when the polishing head 14 enters the round part of the inner wall of the tubular casting, the polishing head 14 can also continuously polish the inner wall of the round part under the driving of the rotating ring 13, and along with the forward movement of the propelling assembly 2 which slowly pushes the polishing assembly 1, the polishing head 14 can completely polish all the inner walls of the tubular casting, and the polishing is sufficient.

Propulsion assembly 2 includes a plurality of fixed connection's propulsion unit in proper order, propulsion unit includes base 21 and at least three evenly distributed's third cylinder 22 on the lateral wall of base 21, adopt four third cylinders 22 in this embodiment, every third cylinder 22's output all is provided with two spacing gyro wheels 23, base 21's one end articulates through connecting rod 24 has connecting seat 25, connecting rod 24's both sides are provided with a telescopic link 26 respectively, telescopic link 26's both ends are articulated with connecting seat 25 and base 21 respectively, spring 27 has been cup jointed on the telescopic link 26. As shown in fig. 1 and 2, the connecting seat 25 of the propelling unit matched with the grinding assembly 1 can be fixedly connected with the tail end of the motor 11, the base 21 of the propelling unit can be fixedly connected with the connecting seat 25 of the next propelling unit, and so on. As the grinding assembly 1 and the propulsion unit are progressively advanced into the radiused portion of the tubular casting, the connecting plate is allowed to rotate as shown in figure 1 as the connecting plate and base 21 are articulated by the link 24, thereby continuing to propel the grinding assembly 1 into movement within the tubular casting. By providing the telescopic rod 26 and the spring 27, the propelling unit can adapt to the curvature of the round corner when the sanding assembly 1 passes through the round corner part of the tubular casting, one side of the spring 27 is compressed and the other side of the spring 27 is extended, which enables the worker to easily push the sanding assembly 1 to gradually sand the inner wall of the round corner part by pushing the propelling assembly 2.

Preferably, a first gear 143 is rotatably mounted on the first cylinder 141, a second gear 144 is disposed on one side of the first gear 143, a third gear 145 which rotates synchronously with the grinding wheel 142 is disposed on one side of the grinding wheel 142, the second gear 144 is engaged with the first gear 143 and the third gear 145, and the second gear 144 is respectively fixed with the first gear 143 and the second gear 144 by two limit frames 146. By providing the two stop frames 146 and the second gear 144, when the first cylinder 141 extends or contracts, the first gear 143 can always drive the third gear 145 to rotate via the second gear 144.

When the motor 11 is operated, the fourth gear 161 can drive the fifth gear 162 to rotate, the fifth gear 162 can drive the rotating ring 13 to rotate on the positioning ring 12 through the meshing with the first gear pattern 163, and since the second gear pattern 164 is meshed with the first gear 143, when the first gear 143 rotates along with the rotating ring 13, the first gear 143 can rotate due to the meshing with the second gear pattern 164, so that the grinding wheel 142 is finally driven to rotate through the second gear 144 and the third gear 145, and the inner wall of the tubular casting is ground.

The first cylinder 141, the second cylinder 151 and the third cylinder 22 of the present invention are simple small micro cylinders, and may be called as pneumatic telescopic rods.
