When it is desired to grind the weld of the workpiece 600: first, a workpiece 600 is placed at a workpiece mounting position 201; then, driving the corresponding grinding device 100 to move relative to the frame 200 by using a movable driving piece according to the specification and the size of the workpiece 600; then, adjusting the angle of the grinding device 100 relative to the frame 200 according to the shape of the workpiece 600 so that the grinding device 100 is aligned with the weld of the workpiece 600; and finally, starting the polishing device 100 to polish. Therefore, the polishing equipment in the embodiment can be suitable for workpieces 600 of various specifications, sizes and shapes, can reduce the labor intensity of workers and improve the polishing efficiency, and can prevent the workers from being influenced by dust generated in the polishing process due to the fact that the workers contact the workpieces 600 closely for a long time.

The movement drive may include only one of the translation drive 160 and the lift drive, or both the translation drive 160 and the lift drive. For example, the movable driving member includes a translational driving member 160 and a lifting driving member, the translational driving member 160 is disposed on at least one side of the workpiece mounting location 201 and connected to the rack 200, the lifting driving member corresponds to the polishing devices 100 on the same side of the translational driving member 160 one by one, that is, the lifting driving member and the translational driving member 160 are located on the same side of the workpiece mounting location 201, and the number of the lifting driving members is the same as that of the polishing devices 100 on the same side of the workpiece mounting location, that is, they correspond to one by one; the lifting driving member is respectively connected with the corresponding polishing devices 100 and the translation driving member 160 on the same side, that is, all the polishing devices 100 on the same side of the workpiece mounting position 201 share the same translation driving member 160; the translation driving member 160 is used to drive the lifting driving member to move horizontally, and the lifting driving member is used to drive the corresponding polishing device 100 to move up and down.

Taking the case that the translational driving member 160 adopts a nut-and-screw mechanism and the lifting driving member adopts a lifting cylinder, specifically, as shown in fig. 9 and 10, the translational driving member 160 includes a fixed plate 161, a moving plate 162, a screw 163, a moving block, and a translational motor 164; the fixed plate 161 and the moving plate 162 are oppositely arranged, the fixed plate 161 is fixed on the rack 200, two ends of the lead screw 163 are rotatably installed on one side of the fixed plate 161 facing the moving plate 162, and one end of the lead screw 163 is in transmission connection with an output shaft of the translation motor 164 through a gear assembly; the moving block is fixed on one side of the moving plate 162 facing the fixed plate 161, and is provided with a threaded hole transversely penetrating through the moving block, the moving block is in threaded fit with the lead screw 163 through the threaded hole, the cylinder body of the lifting cylinder is fixed on the moving plate 162, and the piston rod of the lifting cylinder is fixed on the polishing device 100. When it is desired to translate the sander 100 from side to side, the translation motor 164 is activated to rotate the lead screw 163. Because the two ends of the screw 163 are mounted on the fixing plate 161, and the moving block is in threaded connection with the screw 163, the moving block can drive the moving plate 162 to move relative to the screw 163 in the rotation process of the screw 163, and then drive the lifting cylinder and the polishing device 100 to move synchronously, so that the polishing device 100 approaches or is far away from the weld joint. When the polishing device 100 needs to move up and down, the lifting cylinder is started to drive the polishing device 100 to move up and down. In addition, in view of the small volume of the moving block, in order to improve the stability of the moving plate 162 during the translation process, as shown in fig. 9, a boss 161.1 extending along the length direction is formed on one side of the fixed plate 161 facing the moving plate 162, a lead screw groove 161.2 extending along the length direction is formed on the boss 161.1, one end of the lead screw 163 is transversely inserted into the lead screw groove 161.2, and the other end is connected with the translation motor 164 through a gear assembly; a guide groove is formed in a side of the moving plate 162 facing the fixed plate 161, and a boss 161.1 is slidably fitted in the guide groove. In order to prevent the moving plate 162 from being separated from the fixed plate 161, the guide groove is a dovetail groove, and the boss 161.1 has a dovetail structure fitted to the dovetail groove.

As shown in fig. 10, the lifting driving member is connected to the translation driving member 160 by a second fastener such as a bolt assembly, the translation driving member 160 is formed with a first adjusting portion corresponding to the lifting driving member one by one, and the lifting driving member is formed with a second adjusting portion; one of the first and second adjustment portions is a second arc-shaped hole 181, and the other is a second mounting hole to be fitted with a second fastener. As above, the translation driving member 160 includes the connecting plate 180 in addition to the moving plate 162 and the fixing plate 161, the polishing apparatus 100 is connected to the connecting plate 180 by the lifting driving member, and the connecting plate 180 is fixed to the moving plate 162. Wherein, the lifting driving member is formed with a second mounting hole, and the connecting plate 180 is formed with a second arc hole 181. During installation: firstly, aligning the second mounting hole of the lifting driving piece with the second arc-shaped hole 181 of the connecting plate 180, namely, enabling the projection of the second mounting hole on the connecting plate 180 to fall into the second arc-shaped hole 181; then, a screw rod of the bolt sequentially passes through the second mounting hole and the second arc-shaped hole 181; finally, the nut is screwed into the screw of the bolt until the lifting driving member is firmly fixed on the connecting plate 180. When the angle of the polishing apparatus 100 with respect to the frame 200 needs to be adjusted, that is, when the angle of the lifting drive member with respect to the frame 200 needs to be adjusted, the nut is loosened and the lifting drive member and the polishing apparatus 100 are integrally rotated slightly until the nut is tightened again after the angle of the polishing apparatus 100 with respect to the frame 200 reaches a designated angle. In view of the lifting driving member and the grinding device 100 are heavy and large in size, in order to avoid loosening the nut, the lifting driving member and the grinding device 100 are integrally rotated around the screw rod relative to the connecting plate 180, the first end of the lifting driving member is hinged to the connecting plate 180, and the second end of the lifting driving member is provided with a second mounting hole. Therefore, after the nut is unscrewed, a worker only needs to hold the second end of the lifting driving piece by one hand to slightly rotate, and then the worker can screw the nut by the other hand after rotating in place, so that the labor intensity of the worker is reduced, and the safety is improved.

As shown in fig. 5 to 8, the polishing apparatus 100 includes a base 110, a polishing belt 120, a pulley assembly including a plurality of first pulleys 131 rotatably mounted on the base 110, the plurality of first pulleys 131 being drivingly connected by the polishing belt 120, and a driving mechanism 150; the first pulleys 131 at least partially protrude out of the base 110, so that the polishing belt 120 located between two adjacent first pulleys 131 forms a polishing area; and a driving mechanism 150 for driving the first pulley 131 to rotate.

Further, in order to ensure effective contact between the polishing belt 120 and the weld, the angle of the polishing area may need to be finely adjusted when polishing the weld, and thus in order to achieve fine adjustment of the polishing angle, the angle of at least one first pulley 131 of two adjacent first pulleys 131 is adjustable. Because the plurality of first pulleys 131 are in transmission connection through the polishing belt 120, and the angle of at least one first pulley 131 in two adjacent first pulleys 131 is adjustable, when the polishing angle needs to be finely adjusted, a worker does not need to move the workpiece 600 or the whole polishing device 100, and only needs to adjust the angle of the first pulley 131, the inclination angle of the polishing belt 120 between two adjacent first pulleys 131 relative to the workpiece 600 can be changed, so that the fine adjustment of the polishing angle is realized. It can be seen that the fine adjustment of the grinding angle in this embodiment is realized by adjusting the angle of the first pulley 131, and compared with the workpiece 600 or the whole grinding device 100, the weight and the volume of the first pulley 131 are very small, so that the operation is convenient and fast, the fine adjustment angle is easy to control, and the safety is high.

It should be noted that there are various ways to realize the angle adjustment of the first pulley 131, for example:

mode one, mechanical mode: as shown in fig. 5 and 6, the sanding device 100 further includes an adjustment plate 140, and at least one first pulley 131 is rotatably coupled to the adjustment plate 140; the adjusting plate 140 and the base 110 are coupled by a first fastener such as a bolt assembly, and one of the adjusting plate 140 and the base 110 is formed with a first arc-shaped hole 141 and the other is formed with a first mounting hole 111 to be fitted with the first fastener.

The following takes as an example that the two first pulleys 131 are both mounted on the adjustment plate 140: as shown in fig. 6, the adjustment plate 140 has a substantially triangular shape, two first pulleys 131 are respectively mounted at two corners of the adjustment plate 140 through a rotation shaft, a first arc-shaped hole 141 is formed at the other corner of the adjustment plate 140, and the base 110 is formed with a first mounting hole 111. When the adjusting plate 140 is installed, the adjusting plate 140 is placed on the base 110, so that the first arc-shaped hole 141 is aligned with the first installation hole 111, that is, the projection of the first installation hole 111 on the adjusting plate 140 falls into the first arc-shaped hole 141; then, a screw rod of the bolt sequentially passes through the first arc-shaped hole 141 and the first mounting hole 111; finally, the nut is screwed into the bolt shaft until the adjustment plate 140 is firmly fixed to the base 110. When the angle of the first pulleys 131 needs to be adjusted, the nut is loosened and the adjusting plate 140 is slightly rotated until the inclination angle of the polishing belt 120 between the two first pulleys 131 reaches a specified angle, and then the nut is tightened again, so that the adjusting plate 140 is restrained by the bolt and the nut and cannot fall off the base 110 in the whole adjusting process.

In order to improve the adjustment accuracy and facilitate the operation of the worker, the base 110 is provided with angle calibration lines 112, and one end of the adjustment plate 140 facing the angle calibration lines 112 is provided with a pointer 142 extending to the angle calibration lines 112. The pointer 142 may be formed at the tip of the adjustment plate 140 by cutting, casting, or the like, or may be a pointer attached to the adjustment plate 140.

Mode two, electric mode: the polishing apparatus 100 further includes a support plate and an adjusting motor fixed to the base 110, at least one first pulley 131 is installed at one end of the support plate, a rotating shaft is formed at the other end of the support plate, and the rotating shaft of the support plate is fixedly connected to an output shaft of the adjusting motor. Of course, the rotating shaft of the supporting plate can also be in transmission connection with the output shaft of the adjusting motor through a gear assembly. In this case, the grinding apparatus 100 may further include a controller, and the base 110 is provided with an input button, and the controller is electrically connected to the adjustment motor and the input button, respectively. When the angle of the first pulley 131 needs to be adjusted, the worker sets the angle of the first pulley 131 to be rotated through the input button and starts the adjusting motor, and the adjusting motor drives the support plate to rotate by the corresponding angle under the control of the controller. It is thus clear that mode two compares with mode one more intelligently, the angle modulation is more accurate, but mode one cost is cheaper, specifically adopts which kind of mode can select according to actual need. Of course, the manner of achieving the angle adjustment of the first pulley 131 is not limited to the above two.

In addition, it should be noted that, in order to achieve fine adjustment of the grinding angle, the plurality of first pulleys 131 may be adjusted synchronously, that is, as described above, two first pulleys 131 are installed on the same adjusting plate 140 or the same supporting plate, or of course, the plurality of first pulleys 131 may be adjusted individually, that is, two first pulleys 131 are installed on two first adjusting plates 140 or the same supporting plate.

As shown in fig. 5 and 7, the pulley assembly further includes a second pulley 132 connected to the driving mechanism 150, the second pulley 132 is rotatably mounted to the base 110, and the first pulley 131 and the second pulley 132 are drivingly connected by the grinding belt 120. This arrangement provides the benefit of not only improving the stability of the sheave assembly, but also extending the length of the grinding belt 120, thereby reducing the number of contacts each region of the grinding belt 120 with the workpiece 600, extending the life of the grinding belt 120, and reducing the number of times the grinding belt 120 is replaced. It should be noted that the driving mechanism 150 may be, but is not limited to, a driving motor or a handle. Taking the driving mechanism 150 as an example, as shown in fig. 7 and 8, the driving motor is fixed on a side of the base 110 facing away from the second pulley 132, the base 110 is formed with a shaft hole, and an output shaft of the driving motor passes through the shaft hole to be fixedly connected with the second pulley 132 on the upper portion of the base 110. When the driving motor drives the second pulley 132 to rotate, the second pulley 132 drives the first pulley 131 to rotate synchronously through the grinding belt 120 under the action of friction force.

As shown in fig. 5, the number of the second pulleys 132 is plural, all the first pulleys 131 and all the second pulleys 132 are distributed in a polygon, and all the first pulleys 131 are disposed adjacent to each other. To further extend the length of the sanding belt 120, the pulley assembly further includes at least one third pulley 133, the third pulley 133 being rotatably mounted to the base 110; the third pulley 133 is positioned within the polygon, and the polishing belt 120 positioned between two adjacent second pulleys 132 or the polishing belt 120 positioned between the first pulley 131 and the adjacent second pulleys 132 is wound around the third pulley 133. Based on the orientation shown in fig. 5, the pulley assembly in this embodiment includes two first pulleys 131, two second pulleys 132 and a third pulley 133, the two first pulleys 131 and one second pulley 132 are located at the lower portion of the base 110, the second pulley 132 is located at the upper portion of the base 110, and the other second pulley 132 is located at the upper portion of the base 110, so that the two first pulleys 131 and the two second pulleys 132 are distributed in a quadrilateral shape, that is, the two first pulleys 131 and the two second pulleys 132 respectively form four vertices of the quadrilateral shape, and the two first pulleys 131 and the two second pulleys 132 are in transmission connection through the polishing belt 120; the third pulley 133 is located at the middle of the base 110 and within the quadrangle, and the polishing belt 120 between the first pulley 131 and the adjacent second pulley 132 passes around the third pulley 133, that is, the polishing belt 120 passes around the second pulley 132 located at the upper portion of the base 110, the second pulley 132 located at the lower portion of the base 110, the third pulley 133, and the two first pulleys 131 in sequence.

In addition, to facilitate replacement of the sanding belt 120, a first pulley 131, a second pulley 132, and/or a third pulley 133 may be movably disposed on the base 110.

Wherein the tensioning drive 170 may be, but is not limited to, an air cylinder or a nut and screw mechanism.

In order to prevent the grinding device 100 from being affected by the grinding debris, such as jamming of the rotating shaft of the pulley assembly, and at the same time prevent the grinding debris from being sucked into the grinding device, as shown in fig. 3, 11 and 12, the grinding apparatus further includes a dust box 300 and a fan 400, the dust box 300 is at least partially located below the workpiece mounting location 201, a dust collection opening 311 located below the workpiece mounting location 201 is formed on the top surface of the dust box 300, and a fan mounting hole for mounting the fan 400 is formed on the wall surface of the dust box 300 away from the dust collection opening 311. In order to facilitate periodic cleaning of the dust box 300, the dust box 300 is movably disposed below the workpiece mounting position 201. In addition, in order to facilitate the movement of the dust box 300 during cleaning, a brake wheel is provided at the bottom of the dust box 300.

As shown in fig. 12, the dust box 300 includes a guide plate 330, a first case 310 and a second case 320, the first case 310 includes a dust storage chamber and a dust falling chamber which are horizontally distributed, and a dust collection port 311 corresponding to the dust falling chamber is formed on a top surface of the first case 310; the second box body 320 is arranged above the dust storage cavity and is communicated with the dust storage cavity, namely, the first box body 310 and the second box body 320 form an L-shaped structure; a fan mounting hole is formed in the side wall of the second box body 320 far away from the dust collecting port 311, and the fan 400 is mounted in the second box body 320; the side wall of the second housing 320 adjacent to the dust collecting opening 311 is provided with a guide opening 321 communicated with the dust collecting opening 311, the top end of the guide plate 330 is fixed at the top end of the guide opening 321, and the guide plate 330 is inclined towards the dust storage cavity from the top end to the bottom end thereof. Since the dust collection port 311 is located below the workpiece mounting location 201, most of the debris generated during the grinding process will fall directly through the dust collection port 311 into the dust falling chamber. Meanwhile, other debris generated in the grinding process can be sucked into the dust falling cavity under the suction action of the fan 400. Since the air suction opening of the fan 400 is blocked by the guide plate 330, the guide plate 330 is inclined toward the dust storage chamber from the top end to the bottom end thereof, so that the air direction in the dust box 300 can be changed by the presence of the guide plate 330, that is, the debris generated by the grinding enters the dust storage chamber obliquely downward along the guide plate 330 under the suction of the fan 400 and is finally accumulated at the corner of the dust storage chamber away from the dust collection opening 311.

As shown in fig. 4, the grinding apparatus 100 further includes a housing 500 covering the outside of the frame 200. The presence of the hood 500 not only prevents debris generated by sanding from flying in the air, but also reduces noise to some extent. The side wall of the rack 200 is provided with a window corresponding to the workpiece mounting position 201, so that a worker can place the workpiece 600 in the workpiece mounting position 201 through the window.
