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 6, the grinding device for an aluminum alloy fuel storage tank according to an embodiment of the present invention includes a spindle 13, a sleeve 22 and a grinding head 224, where the spindle 13 is vertically arranged and can rotate and lift, in this embodiment, the bottom of the frame 1 is a base 11, the top of the frame 1 is a machine head 12, the spindle 13 is mounted on the machine head 12, and a power device is provided in the machine head 12 to drive the spindle 13 to rotate and lift, and the structure of the spindle can be a structure of a drilling machine, so that many prior art schemes for realizing the rotation and lift of the spindle 13 are provided, and details are not described herein.
The base 11 is provided with a positioning seat 14, as shown in fig. 4, an opening of the aluminum alloy fuel storage tank to be polished can be buckled on the positioning seat 14 to realize positioning.
As shown in fig. 2, a vertical support rod 2 is fixedly connected to one side of the bottom of the main shaft 13, an inclined angle bracket 21 is fixedly connected to the bottom of the support rod 2, a sleeve one 22 is hinged to the end of the inclined angle bracket 21, a hinge shaft of the sleeve one 22 is intersected with the axial lead of the main shaft 13, a guide rod one 221 is movably inserted into the sleeve one 22, and a polishing head 224 is installed at the end of the guide rod one 221. The first sleeve 22 and the main shaft 13 are in a coplanar relationship, the polishing head 224 can rotate around the hinge shaft of the inclined bracket 21 and the first sleeve 22 by arranging an angle adjusting mechanism capable of changing the included angle between the first sleeve 22 and the main shaft 13, and when the main shaft 13 rotates, the polishing head 224 can simultaneously perform circular motion around the axial lead of the main shaft 13, so that the cylindrical inner wall of the fuel storage tank is polished.
In a possible embodiment, a spring may be sleeved on the guide rod one 221 between the polishing head 224 and the sleeve one 22 to form a self-adaptive interference mechanism, the polishing head 224 may be kept in contact with the inner wall of the fuel storage tank under the action of the spring, when the end of the fuel storage tank is in a conical shape, a hemispherical shape or other revolution shape, the polishing head 224 may be kept in contact with the inner wall of the fuel storage tank under the action of the spring, the polishing head 224 may perform circular motion and lifting motion to polish along the inner wall of the cylindrical connection portion of the fuel storage tank when the main shaft 13 rotates and lifts, and the polishing head 224 may sweep the curved portion of the end of the fuel storage tank through the use of the angle adjusting mechanism to complete the polishing of the curved portion.
In this embodiment, the angle adjusting device includes an electric push rod 23 parallel to the support rod 2 and a rod sleeve 231 movably sleeved on the support rod 2, one end of the electric push rod 23 is fixed to the support rod 2 (or fixed to the main shaft 13), the other end of the electric push rod 23 is fixed to the rod sleeve 231, a connecting rod 232 is hinged between the rod sleeve 231 and the side wall of the first sleeve 22, by using the electric push rod 23, the electric push rod 23 can move the rod sleeve 231 along the support rod 2, which enables the rod sleeve 231 to pull the first sleeve 22 through the connecting rod 232, so that the first sleeve 22 rotates around a hinge axis of the inclined bracket 21 and the first sleeve 22, thereby changing an included angle between the first sleeve 22 and the main shaft 13, that is, changing an included angle between the polishing head 224 and the main shaft 13, and enabling the polishing head 224 to move along a curved surface at the end of the fuel storage tank.
The inclined bracket 21 is arranged to enable the rotation center of the sleeve I22 to be on the axis of the main shaft 13, so that when the electric push rod 23 works, the sleeve I22 can rotate to the degree that the axis is overlapped with the axis of the main shaft 13, the rotation range of the sleeve I22 is 0-90 degrees, and the application range is wide.
Through the above arrangement, the lifting and the rotation of the main shaft 13 can drive the lifting and the circular motion of the polishing head 224, thereby realizing the polishing of the inner wall of the cylindrical connecting part of the fuel storage box, when the funnel-shaped end part of the fuel storage box needs to be polished, the electric push rod 23 is started, the first sleeve 22 is pulled through the connecting rod 232 to rotate by taking the hinging shaft of the inclined strut 21 and the first sleeve 22 as the center, thereby realizing the movement of the funnel-shaped end part of the polishing head 224 along the fuel storage box, the contact with the inner wall of the fuel storage box can be maintained under the action of the self-adaptive conflict mechanism (such as a spring), and the polishing work of the inner walls of the two parts of the fuel storage box is completed.
If the friction between the polishing head 224 and the inner wall of the fuel storage tank is simply maintained by sleeving the spring on the guide rod one 221 between the polishing head 224 and the sleeve one 22, there is a significant disadvantage that the fuel storage tank structure shown in fig. 2 has a funnel-shaped end portion instead of a regular hemisphere, which causes the compression degree of the spring to gradually increase when the polishing head 224 rotates around the hinge shaft of the inclined bracket 21 and the sleeve one 22, and the larger the difference between the radius and the height of the funnel-shaped end portion of the fuel storage tank, the larger the deformation distance of the spring is, so that when the polishing head 224 polishes different positions of the end portion of the fuel storage tank, the pressure change between the polishing head 224 and the inner wall of the fuel storage tank is large, which results in very uneven polishing.
To further solve this problem, as shown in fig. 2, 3, 4 and 6, the adaptive interference mechanism adopted in this embodiment includes a second sleeve 24, a third sleeve 25 and a limit ball 254. As can be seen from fig. 4, sleeve two 24 and sleeve three 25 and sleeve one 22 are welded together. As can be seen from fig. 6, the projections of the first sleeve 22, the second sleeve 24 and the third sleeve 25 in the vertical direction (the top view direction) intersect at a point on the extension line of the axis line of the main shaft 13. Meanwhile, the projection of the second sleeve 24 in the vertical direction is located in the middle of the projections of the first sleeve 22 and the third sleeve 25 in the vertical direction, the second guide rod 241 and the third guide rod 251 are movably inserted in the second sleeve 24 and the third sleeve 25 respectively, the limiting ball 254 is fixedly connected with the end portion of the third guide rod 251, the end, away from the second sleeve 24, of the second guide rod 241 is fixedly connected with the limiting plate 242, as can be seen from fig. 6, the limiting plate 242 is perpendicular to the second guide rod 241, meanwhile, the limiting plate 242 is also provided with the limiting groove 244 perpendicular to the second guide rod 241, and the second spring 243 is sleeved on the second guide rod 241 between the limiting plate 242 and the second sleeve 24.
A first limiting block 225 is movably sleeved on the first guide rod 221, the first limiting block 225 can be in sliding fit with the limiting groove 244, a second limiting block 252 is fixedly connected to the third guide rod 251, and the second limiting block 252 is in sliding fit with the limiting groove 244. therefore, under the action of the second spring 243, the second limiting block 252 can be pushed by the limiting groove 244 through the limiting groove 242, so that the limiting ball 254 fixedly connected with the third guide rod 251 can be pushed against the inner wall of the fuel storage box, the intersection point of the projections of the first sleeve 22, the second sleeve 24 and the third sleeve 25 in the vertical direction is taken as the center, and the distance between the first limiting block 225 and the circular track and the distance between the second limiting block 252 and the circular track are always equal. In order to ensure that the limiting ball 254 and the polishing head 224 are both in the plane of the circular track, a fourth guide rod 253 is fixedly connected to the limiting plate 242, the limiting ball 254 is fixed at the end of the fourth guide rod 253, and the fourth guide rod 253 is parallel to the third guide rod 251 and is overlapped with the vertical projection of the fourth guide rod 253.
When the funnel-shaped end of the fuel tank is hemispherical, the first stopper 225 is equidistant from the inner wall of the fuel tank, and the second stopper 252 is equidistant from the inner wall of the fuel tank. The first spring 227 is sleeved on the first guide rod 221 between the first limiting block 225 and the polishing head 224, the adjusting nut 226 is installed on the first guide rod 221 on the side, away from the polishing head 224, of the first limiting block 225 in a threaded mode, the deformation range of the first spring 227 can be changed by changing the position of the adjusting nut 226, and as the distance between the first limiting block 225 and the inner wall of the fuel storage tank and the distance between the second limiting block 252 and the inner wall of the fuel storage tank are equal, the pressure of the first spring 227 on the polishing head 224 is guaranteed to be unchanged, the pressure between the polishing head 224 and the inner wall of the fuel storage tank can be kept stable, and the polishing uniformity is guaranteed.
When the funnel-shaped end of the fuel tank is not hemispherical, such as the shape shown in fig. 4, there is a small difference between the distance between the first stopper 225 and the inner wall of the fuel tank, and the distance between the second stopper 252 and the inner wall of the fuel tank. The smaller the angle between the first sleeve 22 and the second sleeve 24, the smaller the difference between the distance between the first limiting block 225 and the inner wall of the fuel tank and the distance between the second limiting block 252 and the inner wall of the fuel tank. Thereby reducing the range of pressure variation between the sanding head 224 and the inner wall of the fuel reservoir. The problem that when the polishing head 224 is in self-adaptive collision with the inner wall of the fuel storage tank, the pressure change between the polishing head 224 and the inner wall is large is further solved.
As shown in fig. 4, since the junction between the connection portion and the funnel-shaped end portion of the fuel tank naturally forms a corner, the conventional sanding head 224 cannot be sanded into the corner when sanding. Therefore, the embodiment of the present invention proposes the polishing head 224 shown in fig. 5, which includes a tapered portion 2241 and a curved surface portion 2242, wherein the tapered portion 2241 of the polishing head 224 is in contact with the cylindrical connecting portion when the cylindrical connecting portion of the fuel tank is polished, and the curved surface portion 2242 of the polishing head 224 is in contact when the funnel-shaped end portion of the fuel tank is to be polished. And the corners of the connection portion of the fuel tank and the funnel-shaped end portion are ground by the edges between the tapered portion 2241 and the curved portion 2242 of the grinding head 224.
In order to achieve the above-mentioned change of the angle of the polishing head 224, the present invention provides an angle following mechanism. The end part of the first guide rod 221 is fixedly connected with a fixed frame 222, a rotating frame 223 is hinged on the fixed frame 222, and the sanding head 224 is arranged on the rotating frame 223. The angle follow-up mechanism is arranged to enable the rotating frame 223 to rotate when the included angle between the first sleeve 22 and the main shaft 13 changes, so that the angle of the polishing head 224 also changes, and the edge of the polishing head 224 can polish the corner of the fuel storage tank.
Specifically, the angle follow-up mechanism comprises a limiting sleeve 3 fixedly connected to the side wall of a first sleeve 22, a first bevel gear 31 is rotatably mounted in the limiting sleeve 3, a flower shaft 33 movably penetrates through the first bevel gear 31, the flower shaft 33 is in spline fit with the first bevel gear 31, a second bevel gear 32 is fixedly connected to the inclined frame 21, and the first bevel gear 31 is meshed with the second bevel gear 32, so that when the first sleeve 22 and the inclined frame 21 rotate relatively, the second bevel gear 32 can drive the first bevel gear 31 to rotate by a certain angle, and the first bevel gear 31 drives the flower shaft 33 to rotate by a certain angle.
One side of the fixed frame 222 is provided with a rotatable fixed sleeve 34, and the fixed sleeve 34 is sleeved on the spline shaft 33, so that when the polishing head 224 moves along the direction of the first guide rod 221, the fixed sleeve 34 can move together with the spline shaft 33 and maintain the transmission relationship between the spline shaft 33 and the bevel gear 31. One end of the spline shaft 33 close to the polishing head 224 is fixedly connected with a bevel gear three 35, and a bevel gear four 36 meshed with the bevel gear three 35 is fixedly connected to the rotating frame 223, so that when the spline shaft 33 rotates, the bevel gear four 36 can be driven to rotate through the bevel gear three 35, and when the bevel gear four 36 rotates, the angle of the polishing head 224 is changed. Therefore, when the included angle between the sleeve I22 and the main shaft 13 changes, the angle of the polishing head 224 also begins to change, the cylindrical connecting part of the fuel storage tank is polished by the conical part 2241 of the polishing head 224, the corner of the fuel storage tank is polished by the edge of the polishing head 224, and the funnel-shaped end part of the fuel storage tank is polished by the curved surface 2242 of the polishing head 224, so that the inner wall of the fuel storage tank is completely polished, and the problem that the polishing head 224 is easily and quickly abraded when the fuel storage tank is polished by one part of the polishing head 224 for a long time is solved.
When the cylindrical connecting part of the fuel storage tank is polished, the relative height position of the polishing head 224 and the cylindrical connecting part can be changed through the lifting of the spindle 13, and the polishing head 224 performs circular motion along the cylindrical connecting part through the rotation of the spindle 13, so that the conical part 2241 of the polishing head 224 can completely polish the cylindrical connecting part of the fuel storage tank;
when the corners and the funnel-shaped end parts of the fuel storage tank are ground, the main shaft 13 only needs to rotate continuously, the connecting rod 232 is pulled upwards slowly by using the electric push rod 23, and at the moment, because the first sleeve 22 and the main shaft 13 start to change the angle, the grinding head 224 correspondingly changes the angle through the angle follow-up mechanism, and the edge of the grinding head 224 can grind the corners of the fuel storage tank; when the electric push rod 23 continues to pull the connecting rod 232 upwards, on one hand, the polishing head 224 continues to change in angle, the curved surface part 2242 gradually changes in contact position with the inner wall of the funnel-shaped end part of the fuel storage tank, and the other convenient self-adaptive abutting mechanism also works, so that the contact between the polishing head 224 and the inner wall of the fuel storage tank is maintained within a certain range through the contact between the limiting ball 254 and the inner wall of the fuel storage tank, the pressure between the polishing head 224 and the inner wall of the fuel storage tank is kept to change within a small range, and finally, the inner wall of the fuel storage tank is polished completely and uniformly.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
