The structure disclosed above, wherein:
the hydraulic lifting mechanism 3 is used for driving the punching and grinding assembly 1 to vertically lift and carry out workpiece punching in the descending process, and when the punching and grinding assembly 1 descends to the lowest position, the lower grinding disc 21 is in contact with the lower surface of the workpiece, the grinding piece 11 is in contact with the inside of the forming hole, the upper grinding disc 14 is in contact with the upper surface of the workpiece, and in addition, the grinding piece 11 is connected with the lower grinding disc 21.
Specifically, regarding the connection between the grinding member 11 and the lower grinding disc 21, the following structure is adopted:
at least one mounting groove 22 is formed in the inner wall of the lower grinding disc 21, and a movable limiting block 23 is mounted in each mounting groove 22; a spring 24 is connected between the inner wall of the mounting groove 22 and one end of the limiting block 23, and a guide inclined plane is arranged at the other end of the limiting block 23;

As can be seen from the above and with reference to fig. 1 and 2, based on the above disclosed structure, the principle of the device of the present invention for performing workpiece punching and polishing is as follows:
in fig. 1, the hydraulic lifting mechanism 3 drives the punching and grinding assembly 1 to be positioned at the highest position, and at the moment, a workpiece to be machined can be placed on the workbench 2. Based on the position shown in fig. 1, the hydraulic lifting mechanism 3 is activated to drive the entire punch assembly 1 downward, so that the punch member 12 gradually approaches the workpiece and forms a punch hole in the workpiece.
In order to facilitate the formation of the hole, the bottom of the punching piece 12 is provided with a tip, so that in the descending process, when the punching piece 12 is contacted with the limiting block 23, the limiting block 23 is pushed by the inclined surface of the tip to compress the spring 24 and retract into the mounting groove 22, and the sequential downward movement of the punching piece 12 is further ensured; when the punching and grinding assembly 1 is lowered to the position shown in fig. 2, a hole required on the workpiece is punched and formed, meanwhile, the grinding piece 11 extends into the formed hole, the clamping groove 13 is positioned to the position corresponding to the limiting block 23, and the compressed spring 24 rebounds at the position, so that the limiting block 23 is clamped into the clamping groove 13, and the connection between the lower grinding disc 21 and the grinding piece 11 is realized.
In the position shown in fig. 2, the descending of the punching and grinding assembly 1 is stopped and the driving motor 4 is started, the driving motor 4 drives the punching and grinding assembly 1 to rotate, thereby realizing the synchronous rotation of the grinding piece 11, the upper grinding disc 14 and the lower grinding disc 21, wherein: the grinding piece 11 realizes grinding of the inner wall of the forming hole, the upper grinding disc 14 realizes grinding of the upper surface of the workpiece punching position, and the lower grinding disc 21 realizes grinding of the lower surface of the workpiece punching position, so that all-dimensional grinding of the corresponding position of the workpiece after punching is effectively realized.
Further, as for the upper grinding disc 14, the upper grinding disc is slidably sleeved on the grinding member 11, so that the height of the upper grinding disc 14 can be effectively adjusted. Specifically, the adjusting structure is as follows:
a rotatable threaded sleeve 61 penetrates through the T-shaped seat 6, a threaded rod 62 penetrates through the threaded sleeve 61, the threaded rod 62 is connected with the threaded sleeve 61 in a screwing mode, and the threaded rod 62 is fixedly connected with the upper grinding disc 14.
As can be seen from the above, the threaded sleeve 61 is rotated to form a screw transmission between the threaded sleeve 61 and the threaded rod 62, so as to drive the threaded rod 62 to move up and down, and further drive the upper grinding disc 14 to move up and down.
Further, in the present invention, there is also provided a structure for fixing a workpiece, and the structure includes:
both the two vertical frames of the mounting frame 5 are fixed with transverse plates 51, the two transverse plates 51 are symmetrically positioned at both sides of the punching and grinding assembly 1, a rotatable lead screw 52 is connected between the transverse plates 51 and the workbench 2, a liftable press plate 53 is connected on the lead screw 52 in a rotating and combining manner, and the press plate 53 is in sliding fit with the vertical frames.
From the above, the screw 52 and the pressing plate 53 can form a screw transmission by the rotation of the screw 52, so as to drive the pressing plate 53 to move up and down, and further the pressing plate 53 can be effectively pressed on the upper surface of the workpiece, thereby effectively fixing the workpiece.
In summary, the following linkage structure is provided with respect to the movement of the upper turn table 14 and the platen 53 as described above:
a rotatable first gear 54 and a rotatable second gear 55 are connected between the transverse plate 51 and the transverse frame of the mounting frame 5, a third gear 63 is fixedly sleeved on the threaded sleeve 61, the first gear 54 is meshed with one side of the second gear 55 and is coaxially assembled with the screw rod 52, and when the punching and grinding assembly 1 is lifted to the highest position, the third gear 63 is meshed with the other side of the second gear 55;
a rotating motor 56 is mounted on the cross frame of the mounting frame 5, and the rotating motor 56 is used for driving the first gear 54 or the second gear 55 to rotate.
In summary, in the position shown in fig. 1, the punching and grinding assembly 1 is positioned at the highest position, and at this time, the first gear 54, the second gear 55 and the third gear 63 are sequentially engaged, so that under the driving of the rotating motor 56, the three gears can rotate synchronously, so as to drive the screw rod 52 and the threaded sleeve 61 to rotate synchronously, thereby realizing the synchronous movement of the pressing plate 53 and the upper grinding disc 14, and the moving directions of the pressing plate 53 and the upper grinding disc 14 are the same. From the above, when the workpiece is fixed in the position shown in fig. 1, the positioning height of the upper grinding disc 14 can be effectively limited by the movement of the pressure plate 53 and the pressing of the workpiece, so as to ensure that the upper grinding disc 14 can accurately contact with the upper surface of the workpiece after the punch grinding assembly 1 is lowered.
After the workpiece is punched and polished, the hydraulic lifting mechanism 3 is firstly started, so that the position of the punching and polishing assembly 1 shown in fig. 2 is restored to the position shown in fig. 1, and then the rotating motor 56 is started, so that the upper grinding disc 14 and the pressure plate 53 are synchronously driven to move, the workpiece is conveniently replaced, and the matching accuracy between the upper grinding disc 14 and the pressure plate 53 is ensured.
