Referring to fig. 1, a top surface polishing apparatus is provided.
Structurally, the polishing device is provided with a closable polishing cavity, and the polishing cavity can collect scraps generated by polishing to avoid dust pollution.
For the purpose of explaining the detailed structure of the polishing apparatus, a frame forming a polishing chamber is not shown.
Within the polishing chamber, as shown in fig. 1, there are a jig 520, a tooling table 510, a longitudinal movement assembly 500, a traverse movement assembly 420, a column 400, a lifting assembly 410, and a polishing assembly 100.
Specifically, the longitudinal moving assembly 500 is perpendicular to the traverse moving assembly 420, and one end of the longitudinal moving assembly 500 away from the traverse moving assembly 420 is a loading area for workers, so that products can be conveniently fixed on a clamp 520 for polishing.
At the position of the longitudinal moving assembly 500, a tooling table 510 is arranged at the top of the longitudinal moving assembly 500, and the tooling table 510 is provided with a fixture 520 for fixing a polishing product and a third motor 530 for driving the fixture 520 to horizontally rotate.

At the traverse assembly 420, the column 400 is arranged at the top of the traverse assembly 420, the lifting assembly 410 is arranged on the column 400, and the lifting assembly 410 is used for driving the polishing assembly 100 to lift.
The vertical column 400 and the lifting assembly 410 are provided so that the polishing assembly 100 is located at a high position, and thus, can be lowered from the top down, facilitating the polishing of the top surface of the product.
Moreover, the traverse assembly 420 is located at the bottom of the upright 400, so that the overturning moment generated by the polishing assembly 100, the first bracket 200, the second bracket 300 and the first power member 320 can be reduced, the rigidity of the polishing device can be improved, and the stable polishing can be ensured.
Specifically, the moving direction of the traverse assembly 420 driving the upright column 400 is consistent with the moving direction of the abrasive belt of the polishing assembly 100, so that the abrasive belt can continuously polish different positions of the top surface of the product, and the problem that the contact area between the abrasive belt and the product is small due to the driving wheel 110 is overcome.
With respect to polishing assembly 100, polishing assembly 100 generally includes a sanding belt for polishing, a drive wheel 110 for driving the sanding belt to move and bring the sanding belt into abutment with the product, a driven wheel 120 for tensioning the sanding belt, and a first motor 130 for rotating drive wheel 110.
That is, the first motor 130 drives the driving wheel 110 to rotate, the driving wheel 110 drives the abrasive belt to move, the abrasive belt polishes the product, and meanwhile, the driving wheel 110 supports the abrasive belt, specifically, the driving wheel 110 abuts against one side of the abrasive belt, and further, the other side of the abrasive belt abuts against the product, that is, the driving wheel 110 directly provides the pressure of the abrasive belt to extrude the product.
The rip member 500, the traverse member 420 and the lift member 410 are preferably driven by a combination of motors, screws and nuts, which are easy to understand and will not be explained in detail.
Conventionally, when polishing the top surface of a product, the lifting assembly 410 is used to adjust the position of the polishing assembly 100 according to the height of the product, so that the abrasive belt of the polishing assembly 100 elastically touches the top surface of the product for polishing.
However, vertically lifting and lowering the polishing assembly 100 requires the use of a force equal to the gravity of the polishing assembly 100, and thus the power consumption is high.
Referring to fig. 1 and 3, in order to solve this problem, the present embodiment is modified in that a first bracket 200, a second bracket 300, and a first power member 320 are provided.
The first bracket 200 is disposed at the bottom of the polishing assembly 100 for mounting the polishing assembly 100, and meanwhile, the second bracket 300 is disposed at one side of the first bracket 200 in the horizontal direction, the second bracket 300 is hinged to the first bracket 200, the second bracket 300 is fixed to the lifting assembly 410, that is, the lifting assembly 410 drives the second bracket 300 to lift.
The first power member 320 is disposed at the bottom of the first bracket 200, and is connected to a side of the first bracket 200 away from the second bracket 300, for driving the first bracket 200 to rotate and lift.
The first power member 320 may be mounted on the second support 300 and may also be mounted on the lifting assembly 410, and should be kept stationary with the second support 300 while driving the first support 200 to be lifted.
After improvement, the first support 200, the second support 300 and the first power member 320 are arranged in the embodiment, so that the polishing assembly 100 is rotationally lifted at the beginning and the end of polishing, and because the center of gravity of the polishing assembly 100 is located in the middle of the first support 200, the force of the first power member 320 for lifting the polishing assembly 100 is smaller than the gravity of the polishing assembly 100, and further, the energy consumption of the polishing device is reduced.
Moreover, the polishing assembly 100 rotates to lift, so that the horizontal deviation is not generated, the product is not accidentally touched, and the product to be polished is powerfully protected.
Furthermore, the polishing assembly 100 rotates to lift, so that the top end of the polishing assembly 100 deviates towards the horizontal direction, and further, the occupied space of the polishing assembly 100 along the vertical direction is reduced, which is beneficial to reducing the occupied space of the polishing device.
Moreover, the top end of the polishing assembly 100 is offset towards the side close to the second bracket 300, so that the center of gravity of the polishing assembly 100 is closer to the center of gravity of the rotation of the first bracket 200, and the first power member 320 can drive the polishing assembly 100 to lift in a more labor-saving manner.
Specifically, the first power member 320 should be a pneumatic cylinder, a hydraulic cylinder, or the like, so as to also make the polishing assembly 100 polish the surface of the product with a constant pressure.
Meanwhile, after the improvement, the lifting assembly 410 mainly adjusts the height position of the polishing assembly 100 to adapt to products with different height specifications. The lift assembly 410 does not act, or makes fewer adjustments, while polishing different individuals of the same product, i.e., the lift assembly 410 does not participate in the repeated polishing process.
Referring to fig. 1 and 2, in some specific embodiments, the polishing apparatus may further include a translation assembly 210, wherein the translation assembly 210 is configured to reciprocally translate the polishing assembly 100.

In the embodiment, the translation assembly 210 is arranged, so that when the abrasive belt polishes the top of a product, the abrasive belt horizontally reciprocates along the width direction of the abrasive belt, so that different positions of the abrasive belt in the width direction polish the same position of the product, and the consistency of the polishing quality is ensured.
In addition, the abrasive belt horizontally reciprocates along the width direction of the abrasive belt, so that the polishing range of the abrasive belt is expanded, scraps are conveniently discharged, the wider abrasive belt is conveniently used for polishing, and the polishing efficiency is improved.
Moreover, the second motor 212 is disposed at the bottom of the first bracket 200, so that the space at the bottom of the first bracket 200 can be fully utilized, the occupation of the space at the top of the first bracket 200 is reduced, the structure is optimized, and the arrangement of the polishing assembly 100 is facilitated.

More advantageously, if the axis of the second motor 212 is parallel to the rotation axis of the first carriage 200, the center of gravity of the polishing assembly 100 and the translation assembly 210 is prevented from shifting away from the second carriage 300, thereby ensuring that the first power member 320 lifts and lowers the first carriage 200 in a labor-saving manner.
The transmission structure between the second motor 212 and the mounting bracket 211 may be a rack and pinion transmission, which is easy to understand.
As an alternative to the transmission structure between the second motor 212 and the mounting bracket 211, the translation assembly 210 may further include a transformation box 213 disposed at the output end of the second motor 212, a vertically disposed eccentric shaft 214 disposed at the output end of the transformation box 213, and a connecting rod 215 connecting the eccentric shaft 214 with the mounting bracket 211.

The transforming box 213 is generally called a gear box to change the driving rate, and of course, in this embodiment, it should also have a direction changing structure like a bevel gear so as to change the driving direction such that the axis of the eccentric shaft 214 is perpendicular to the axis of the second motor 212 and the eccentric shaft 214 is parallel to the axis of the output end of the transforming box 213, but the eccentric shaft 214 is not coincident with the axis of the output end of the transforming box 213, so that the draw bar is repeatedly pulled to reciprocate the mounting frame 211.
It is, of course, apparent that the connecting rod 215 is rotatably connected at both ends to the eccentric shafts 214 and the mounting bracket 211.
