Referring to fig. 1, a top surface polishing apparatus is provided.
Structurally, the polishing device is provided with a closable polishing chamber, and the polishing chamber can collect scraps generated by polishing, so that dust pollution is avoided.
For convenience of explanation of the detailed structure of the polishing apparatus, a frame forming the polishing chamber is not shown.
In the polishing chamber, as shown in FIG. 1, there are a jig 520, a tool table 510, a vertical movement assembly 500, a lateral 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 lateral moving assembly 420, and the end of the longitudinal moving assembly 500 away from the lateral moving assembly 420 is a loading area for personnel, so that the product is conveniently fixed on the fixture 520 for polishing.
At 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 clamp 520 for fixing a product to be polished and a third motor 530 for driving the clamp 520 to horizontally rotate.

At the traversing assembly 420, the upright post 400 is disposed at the top of the traversing assembly 420, the lifting assembly 410 is disposed on the upright post 400, and the lifting assembly 410 is used for driving the polishing assembly 100 to lift.
The stand 400 and the lifting assembly 410 are provided such that the polishing assembly 100 is positioned at a higher position, and thus, can be lowered from the top down, facilitating polishing of the top surface of the product.
In addition, the traversing assembly 420 is located at the bottom of the upright 400, so as to reduce the overturning moment generated by the polishing assembly 100, the first bracket 200, the second bracket 300 and the first power member 320, improve the rigidity of the polishing device, and ensure stable polishing.
In particular, the direction in which traversing assembly 420 moves column 400 is consistent with the direction in which the belt of polishing assembly 100 moves, and also allows the belt to continuously polish different positions of the top surface of the product, overcoming the reality of small contact area between the belt and the product by drive wheel 110.
For the polishing assembly 100, the polishing assembly 100 mainly includes an abrasive belt for polishing, a driving wheel 110 driving the abrasive belt to move and causing the abrasive belt to abut against a product, a driven wheel 120 tensioning the abrasive belt, and a first motor 130 driving the driving wheel 110 to rotate.
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, meanwhile, the driving wheel 110 also supports the abrasive belt, specifically, the driving wheel 110 abuts against one side of the abrasive belt, and then 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 squeeze the product.
The longitudinal movement assembly 500, the traverse assembly 420 and the lifting assembly 410 are preferably driven by a combination of a motor, a screw and a nut, which are easy to understand and not 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 to perform polishing.
However, the vertical up and down lifting of the polishing assembly 100 requires the use of a force equivalent to the weight of the polishing assembly 100, and consumes a relatively high amount of energy.
Referring to fig. 1 and 3, in order to solve this problem, the present embodiment is specially modified to provide a first bracket 200, a second bracket 300, and a first power member 320.
The first support 200 is disposed at the bottom of the polishing assembly 100, and is used for mounting the polishing assembly 100, meanwhile, the second support 300 is disposed at one side of the first support 200 in the horizontal direction, the second support 300 is hinged to the first support 200, and the second support 300 is fixed on the lifting assembly 410, that is, the lifting assembly 410 drives the second support 300 to lift.
The first power unit 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 bracket 300 or the elevating assembly 410, and should be kept stationary with the second bracket 300 while elevating the first bracket 200.
After improvement, in this embodiment, the first support 200, the second support 300 and the first power member 320 are provided, so that the polishing assembly 100 is rotationally lifted at the beginning of polishing and at 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 lifting the polishing assembly 100 by the first power member 320 is smaller than the gravity of the polishing assembly 100, thereby reducing the energy consumption of the polishing device.
Moreover, the polishing assembly 100 is rotated and lifted, and does not generate deflection along the horizontal direction, and accidental contact with the product is avoided, so that the product to be polished is effectively protected.
Furthermore, the polishing assembly 100 is lifted and lowered in a rotating manner, so that the top end of the polishing assembly 100 is deviated towards the horizontal direction, and further, the occupied space of the polishing assembly 100 along the up-down 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 support 300, so that the center of gravity of the polishing assembly 100 is closer to the center of rotation of the first support 200, and the first power member 320 can drive the polishing assembly 100 to lift more labor-effectively.
In particular, the first power member 320 should be selected to be a cylinder or a hydraulic cylinder, etc., so as to also make the polishing assembly 100 constantly pressurized to polish the product surface.
Meanwhile, after improvement, the lifting assembly 410 mainly adjusts the height of the polishing assembly 100 to adapt to products with different specifications. The lifting assembly 410 does not act or adjusts less when polishing of different individuals of the same product is performed, i.e., the lifting assembly 410 does not participate in the repeated polishing process.

In this embodiment, the translation assembly 210 is provided, so that when the abrasive belt polishes the top of the product, the abrasive belt horizontally reciprocates along the width direction of the abrasive belt, and thus, different positions of the abrasive belt in the width direction polish the same position of the product, and consistency of 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 enlarged, scraps are conveniently discharged, the wider abrasive belt is conveniently used for polishing, and the polishing efficiency is improved.
Furthermore, 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, occupation of the top space of the first bracket 200 is reduced, the structure is optimized, and arrangement of the polishing assembly 100 is facilitated.

More preferably, if the axis of the second motor 212 is parallel to the rotation axis of the first bracket 200, the center of gravity of the polishing assembly 100 and the translation assembly 210 is prevented from being shifted in a direction away from the second bracket 300, so that the first power member 320 is ensured to lift the first bracket 200 with less effort.

The transformation box 213 is commonly called a gearbox to change the transmission rate, and of course, in this embodiment, should also have a bevel gear-like turning structure to change the transmission direction such that the axis of the eccentric shaft 214 is perpendicular to the axis of the second motor 212 and such that the eccentric shaft 214 is parallel to the axis of the output end of the transformation box 213, but the eccentric shaft 214 is not coincident with the axis of the output end of the transformation box 213, to repeatedly pull the pull rod to reciprocate the mounting 211.
Of course, it is apparent that both ends of the connecting rod 215 are rotatably connected to the eccentric shaft 214 and the mounting bracket 211.
