Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the functions of the invention clearer and easier to understand, the technical scheme of the invention is described in detail below. It should be understood by those skilled in the art that the following examples are illustrative of some, but not all, specific embodiments of the invention and therefore the scope of the invention is not limited thereto.

This embodiment has announced a mechanical type linkage polishing equipment, refer to the structure shown in fig. 1, adopt the polishing dish 1 to polish weld 21 behind the drum butt weld, the polishing equipment of this embodiment is still including the shell 5 that is used for installing the polishing dish simultaneously, 5 bottom central authorities of this shell and both sides elastic mounting have in proper order one can vertical gliding polishing dish 1, two locating pieces 2, polishing dish 1 and locating piece 2 can all adopt the spring to install, for example, as shown in fig. 3, the bottom face of locating piece 2 is the circular arc concave surface, locating piece 2 and polishing dish 1 are all contradicted through the chamber bottom of the cavity that cylindrical spring and shell 5 bottom correspond and are met. In addition, when the two positioning blocks 2 are attached to the surface of the cylinder, namely, when the two positioning blocks 2 just contact the surface of the cylinder, the polishing disc 1 does not contact the cylinder, but a certain gap exists, but the corresponding springs of the positioning blocks 2 are compressed along with the continuous downward movement of the shell 5, the positioning blocks 2 gradually move upwards, the polishing disc 1 can gradually contact the welding line 21 and generate stronger and stronger extrusion contact, so that polishing is realized, when the polishing disc 1 polishes the welding line 21 to be level on the outer wall of the cylinder, namely, the welding line 21 is polished to be level, the positioning blocks 2 move upwards to the extreme position, and excessive polishing caused by continuous movement is avoided, and the appearance consistency is influenced. Of course, since the polishing disc 1 needs to be in direct contact with the weld seam 21 and even the cylinder, the present embodiment is designed as a floating polishing structure, that is, a sliding key connection capable of allowing the rotating shaft 3 to move axially is adopted between the rotating shaft 3 of the polishing disc 1 and the motor 4 driving the rotating shaft to rotate, so that on one hand, the polishing disc 1 can move up adaptively, and on the other hand, the torque input receiving relation with the motor 4 is kept during the moving up process.

In addition, in this embodiment, a platform 6 for horizontally placing the cylinder is further disposed below the housing 5, and the platform 6 can vertically move, and specifically, the platform 6 can be lifted by a plurality of hydraulic rods 9 (not shown in the figure). In addition, a groove with an arc-shaped cross section is formed on the bearing platform 6 for placing the welded cylinder, and a groove is preferably additionally formed at the bottom of the groove corresponding to the welding seam 21 to accommodate the welding seam 21 and avoid interfering the horizontal placement of the cylinder. With continued reference to fig. 1-2, a motor 7 is disposed on one side of the platform 6, and a spindle 8 of the motor 4 is concentric with the cylinder disposed at that time, or concentric with the groove on the platform 6; a plurality of slats 10 are fixedly connected to a main shaft 8 of the motor 7 in an annular array mode, a rocker 11 is hinged to each slat 10, a steel ball 12 is fixedly connected to one end of each rocker 11, the steel ball 12 is mainly used for contacting with the inside of the cylinder, the other end of each rocker 11 is connected with a slide pipe 14 horizontally arranged through a plurality of connecting rods 13, all the rockers 11 are synchronously driven through the connecting rods 13 to rotate in an articulated mode, all the rockers 11 are ensured to rotate synchronously, the cylinder is supported in a self-adaptive mode, and the cylinder is fixedly grabbed. In order to realize the function, a guide rod 15 is also required to be inserted into the sliding pipe 14 in a sliding fit manner, one end of the guide rod 15 is fixedly connected to the center of the end part of the main shaft 8, the other end of the guide rod 15 is connected with a pressure-bearing spring 17 in the sliding pipe 14, one end of the sliding pipe 14, which is far away from the wane 11, is fixedly connected with a wedge block 18, and during specific manufacturing, the vertical section of the wedge block 18 is a right triangle, and the bevel edge of the right triangle is positioned on the inclined surface. The inclined plane of wedge 18 can be tangent with the steel ball 19 of the transfer line 20 tip of rigid coupling on shell 5, when using, shelve the welded drum level on cushion cap 6 earlier, then put shell 5 on the drum, make the circular arc concave surface of two locating pieces 2 paste on the face of cylinder of drum, realize preliminary location, make middle polishing dish 1 can preliminary location, reach the welding seam 21 top, then progressively push down shell 5, on the one hand, locating piece 2 is compressed into in the shell 5, then in this point department, polishing dish 1 and welding seam 21 from beginning to contact polish to flush with the face of cylinder of drum at last, shell 5 moves down to the limit with locating piece 2 together. On the other hand, the transmission rod 20 integrally and fixedly connected with the shell 5 moves downwards gradually, then the steel balls 19 contact with the inclined surfaces of the wedge-shaped blocks 18 to push the sliding pipe 14 to move left, then the steel balls 12 of all the warping plates 11 are abutted against the inner wall of the cylinder to center and fix the cylinder, at the moment, the bearing platform 6 moves downwards, the cylinder does not move, the cylinder is lifted and suspended, then the motor 7 rotates to drive the cylinder to rotate, the welding line 21 on the cylinder is in contact with the polishing disc 1 which has moved in place and has polished the welding line 21 to form a notch, so that the whole circle of welding line 21 is polished to be flat, and as long as the polishing disc 1 is not provided with a limiting element, the limiting element can be a cylindrical limiting column at the top of the positioning block 2 in the figure 1, and only depends on the cylindrical spring to transmit force, the clamping in the polishing process can be effectively avoided, and if the limiting column is added, the larger polishing force can be ensured, and the polishing is more thorough; whether the position is limited or not can be selected adaptively.

With reference to fig. 2, the end of the main shaft 8 is fixedly connected with a first disc 9, one end of the first disc 9 facing the slide pipe 14 is provided with slats 10, all the slats 10 are arranged obliquely, so that all the slats 10 are arranged on a conical surface, and the large end of the conical surface is arranged facing the slide pipe 14, and the structure is more reliable. Meanwhile, the slat 10 is hinged to a rocker 11 towards one end of the sliding pipe 14, the rocker 11 is of a V-shaped structure, and corners of the rocker 11 are hinged to the slat 10. The sliding pipe 14 is fixedly connected with a second disc 22 at one end facing the rocker 11, the connecting rods 13 are connected to the second disc 22 in an annular array, the guide rod 15 is fixedly connected to the center of the first disc 9 perpendicularly, and the other end of the guide rod 15 is connected with the pressure-bearing spring 17 through the piston 16, so that the sliding property of the sliding pipe 14 can be well ensured.
