The invention also provides a method of adjusting an adjustable sanding table as defined in any of the above claims, comprising the steps of:
s1, when the height of the grinding table 3 needs to be increased, the adjusting cylinder 8 is started, the adjusting cylinder 8 extends integrally and drives the grinding table 3 to move upwards, the balancing weight 6 moves downwards, the adjusting cylinder 8 is stopped until the position of the grinding table 3 is proper, and the balancing weight 6 and the grinding table 3 keep stable in position under the driving action of the transmission cable 7 and the limiting action of the adjusting cylinder 8;
s2, when the height of the polishing table 3 needs to be lowered, the adjusting cylinder 8 is started, the adjusting cylinder 8 is shortened integrally, the polishing table 3 is driven to move downwards, the balancing weight 6 moves upwards, the adjusting cylinder 8 is stopped until the position of the polishing table 3 is proper, and the balancing weight 6 and the polishing table 3 keep stable in position under the driving action of the transmission cable 7 and the limiting action of the adjusting cylinder 8.
According to the adjustable polishing workbench and the adjusting method thereof provided by the invention, firstly, if a workpiece needs to be positioned through a clamp and the like, a corresponding clamp can be arranged at the top of the polishing bench 3 and used for fixing the position of the workpiece, wherein the specific structure of the clamp can be set according to the work, and meanwhile, the specific structure of the clamp is not within the protection range required by the application; if the workpiece is not required to be fixed, the workpiece is only required to be directly placed on the grinding table 3.
After the work piece is put on the platform of polishing 3, the work piece is applyed and is all is decurrent for platform of polishing 3, the gravity of platform of polishing 3 simultaneously and the gravity of activity body 5 are all decurrent, but because the bottom of activity body 5 this moment is passed through transmission cable 7 and is connected on balancing weight 6, and balancing weight 6 and the platform of polishing 3 between be provided with the regulation jar 8 that length was fixed this moment again, so the platform of polishing 3 this moment, adjust the jar 8, transmission cable 7, activity body 5 etc. has reached a balanced state, the platform of polishing 3 can not the activity downwards promptly, but balancing weight 6 also can not the activity downwards simultaneously, consequently can carry out normal stable polishing. If the shapes of the workpieces are different or larger, the height of the polishing table 3 needs to be adjusted, so that the polishing machine is suitable for workpieces with different sizes, or the positions of the same workpiece with different heights can be polished more conveniently (too high or too low to be polished conveniently), so that the polishing effect is better; meanwhile, different workers have different heights, and the height of the polishing platform 3 can be adjusted at the moment, so that the workers can polish more conveniently, and the polishing effect is further improved.
Moreover, work piece usually, the weight of platform 3 and the movable body 5 of polishing is close with the weight of balancing weight 6, consequently in the in-service use, adjust jar 8 only need bear the frictional force between transmission cable 7 and the location section of thick bamboo 4, and balancing weight 6 and work piece, the movable body 5 with polish the weight difference between the platform 3 can, this moment to adjusting jar 8 require lowerly, production requirement and cost have been reduced, simultaneously because the load of adjusting jar 8 is less, consequently can make and adjust jar 8 have longer life.
When the height of the polishing table 3 needs to be increased, only the adjusting cylinder 8 needs to be started, when the adjusting cylinder 8 extends, the polishing table 3 can be driven to rise, meanwhile, the balancing weight 6 moves downwards, when the height of the polishing table 3 reaches a proper value, the adjusting cylinder 8 is stopped, and the position of the polishing table 3 is stable; similarly, when the height of the grinding table 3 needs to be reduced, the length of the adjusting cylinder 8 is only required to be shortened, and the grinding machine is simple and convenient.
The movable body 5 and the positioning cylinder 4 are both cylindrical, so that the movable body 5 can play a role in blocking an external structure, namely, the clothes of workers and the like are prevented from being wound between the transmission cable 7 and the positioning cylinder 4 in a processing or operation project, and the processing safety is improved; simultaneously also can be fine prevent that iron fillings etc. that polish out from entering into a location section of thick bamboo 4, all played the guard action to each structure of a location section of thick bamboo 4 and inside for the operation of adjusting platform 3 of polishing can stably go on. Meanwhile, a relief hole 9 formed in the movable body 5 is used for an oil pipe (not shown) of the adjusting cylinder 8 (preferably, a cylinder) to pass through.
When the transmission cable 7 bypasses the top of the positioning cylinder 4, the transmission cable is carried out through the movable wheel 10, and the movable wheel 10 is rotatably connected to the positioning cylinder 4, so that the movable wheel 10 can reduce the resistance of the transmission cable 7 when passing through the positioning cylinder 4, and can also reduce the abrasion between the positioning cylinder 4 and the transmission cable 7, and prolong the service lives of the two. Meanwhile, the anti-skid groove 11 can enable the transmission cable 7 to be stably connected to the movable wheel 10, and the use stability is improved.
The outer wall periphery of balancing weight 6 all is provided with a plurality of activity balls 12, so activity ball 12 not only can reduce the resistance when balancing weight 6 goes up and down, has still improved the stability of balancing weight 6 activity simultaneously to and the stability of position in the use. In the process of using the balancing weight 6, the stabilizing rod 13 can also improve the stability of the position of the balancing weight 6. Moreover, when the adjusting cylinder 8 drives the balancing weight 6 to move, a part of acting force is generated to enable the balancing weight 6 to receive a component force in a horizontal direction (the adjusting cylinder 8 cannot completely vertically drive the balancing weight 6 downwards), and then the balancing weight 6 can play a bearing role for the component force in the horizontal direction, so that the burden of the positioning cylinder 4 is reduced, the positioning cylinder 4 is protected, and the positioning cylinder 4 can stably keep the position.
According to the actual conditions, the height of the lifting platform 15 can be adjusted, so that the adjusting spring 16 is in a compressed or extended state, and the degree of compression or extension of the adjusting spring 16 can be adjusted at the same time, so that the lifting platform can be used in cooperation with workpieces with different weights, specifically, for example:
the weight of the processed workpiece is large (relative to the balancing weight 6), the adjusting cylinder 8 is always in a compressed state (the grinding table 3 applies acting force downwards, and the balancing weight 6 applies upward acting force), the adjusting spring 16 is in an extended state at the moment and is used for pulling the balancing weight 6 downwards, so that the magnitude of the compressive force applied to the adjusting cylinder 8 can be reduced to a certain extent, and the adjusting cylinder 8 is protected;
moreover, if the weight of the workpiece to be polished is larger, at this time, the movable rod 25 is firstly lifted upwards, and the movable rod 25 is disengaged from the positioning hole 26, but still remains in the movable hole 24, then the movable rod 25 is rotated, the movable rod 25 drives the driving wheel 21 to rotate, the driving wheel 21 drives the driven wheel 22 and the adjusting screw rod 19 to rotate through the transmission chain 23 (namely a conventional chain), the adjusting screw rod 19 can only rotate and cannot lift, so that the lifting platform 15 in threaded connection with the adjusting screw rod 19 moves downwards, the adjusting spring 16 is lengthened, the downward acting force applied to the counterweight block 6 is larger, and the acting force of the workpiece with larger mass can be resisted;
if the mass of the workpiece is smaller (still larger than the balancing weight 6), the driving wheel 21 is rotated reversely, and the tension action of the adjusting spring 16 on the balancing weight 6 is reduced;
no matter how the lifting platform 15 is adjusted, the purpose is to enable the acting force of the balancing weight 6 and the adjusting spring 16 to be close to balance with the weight of the grinding platform 3, the workpiece and the movable body 5, so that the pressure effect on the adjusting cylinder 8 is reduced.
When the driving wheel 21 is adjusted to be suitable, the movable rod 25 is driven downwards, so that the movable rod 25 is inserted into the positioning hole 26 at the corresponding position, and thus the movable rod 25 realizes the locking of the driving wheel 21, and the position of the adjusting spring 16 can be stably maintained. Wherein if there is no positioning hole 26 below the movable rod 25 at this time, the movable rod 25 can be inserted into the closest positioning hole 26 after being rotated by the minimum angle; since the adjustment of the adjusting spring 16 does not need to be very precise, even a minimum rotation angle does not affect the proper protection of the adjusting cylinder 8.
Similarly, if the weight of the processed work piece is all less (for balancing weight 6), the adjusting cylinder 8 at this moment is in the elongated state all the time (grinding table 3 upwards exerts the effort, and balancing weight 6 exerts decurrent effort), then the adjusting spring 16 at this moment is the state of compression for upwards support balancing weight 6, so alright reduce the tensile force size that adjusting cylinder 8 received to a certain extent, have the guard action to adjusting cylinder 8.
Moreover, if the weight of the polished workpiece is smaller, at this time, the movable rod 25 is firstly lifted upwards, and the movable rod 25 is disengaged from the positioning hole 26, but still remains in the movable hole 24, then the movable rod 25 is rotated reversely, the movable rod 25 drives the driving wheel 21 to rotate, the driving wheel 21 drives the driven wheel 22 and the adjusting screw rod 19 to rotate through the transmission chain 23 (namely a conventional chain), the adjusting screw rod 19 can only rotate and cannot lift, so that the lifting platform 15 in threaded connection with the adjusting screw rod 19 moves upwards, the adjusting spring 16 is further compressed, the mass of the counterweight block 6 is further borne or shared, and the tensile force generated by the adjusting cylinder 8 due to the difference in mass between the counterweight block 6 and the workpiece can be reduced;
if the mass of the workpiece is slightly larger (still smaller than the balancing weight 6), the driving wheel 21 is rotated reversely, and the supporting effect of the adjusting spring 16 on the balancing weight 6 is properly reduced;
also, the purpose of the adjustment of the lifting table 15 is to balance the forces of the weight 6 and the adjusting spring 16 with the weight of the grinding table 3, the workpiece and the movable body 5, thereby reducing the pressure on the adjusting cylinder 8.
When the adjusting screw rod 19 rotates, the plurality of anti-rotation rods 17 below the lifting platform 15 are vertically positioned in the anti-rotation holes 18, so that although the lifting platform 15 is subjected to a horizontal rotation trend acting force (applied by the adjusting screw rod 19), the angle of the lifting platform 15 cannot change due to the anti-rotation rods 17, and the adjusting spring 16 is stably supported. Moreover, the rotation preventing rod 17 can also bear the acting force in the horizontal direction of the lifting platform 15, so that the connection part of the adjusting screw rod 19 and the lifting platform 15 is well prevented from generating overlarge torque force and deforming, and the service life of each structure is ensured.
