DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Please refer to Figure 1-7 As shown; the utility model provides a technical solution: a gantry milling machine belt polishing device, comprising a mounting table 1, the mounting table 1 is provided with a forward and backward moving slide 2 for driving the product to move forward and backward, the mounting table 1 is provided with a horizontally arranged gantry mounting frame 21, the two ends of the gantry mounting frame 21 are respectively provided with a horizontally arranged left moving screw slide 22 and a right moving screw slide 23, the left moving screw slide 22 and the right moving screw slide 23 are respectively provided with a polishing device 3 and a milling device 4, the milling device 4 performs a cutting operation on the product, and the polishing device 3 performs a polishing operation on the product.

[0025] When the utility model is in use, after the product is placed on the movable end of the front and rear movable slides 2 for limit fixing, the milling device 4 can be driven by the right movable screw slide 23 to move horizontally to perform horizontal cutting operations on the surface of the product. Then, the polishing device 3 can be driven by the left movable screw slide 22 to move horizontally to polish the product. The surface of the product after cutting is polished and smooth, thereby improving the processing quality of the milling and grinding compound machine.

[0026] In this embodiment, refer to Figure 3 As shown, the polishing device 3 includes a first slide 30, and the first slide 30 is connected to the moving end of the left movable screw slide 22. A first lifting assembly 31 is provided on the first slide 30, and a product polishing assembly is provided on the moving end of the first lifting assembly 31. When the first lifting assembly 31 works and drives the product polishing assembly to move downward, the position of the sanding belt 36 moves downward, and the surface of the product is polished.

[0027] In this embodiment, refer to Figure 4 and Figure 5 As shown, the product polishing assembly includes a polishing seat 32, on which an adjustment seat 33 slidably matched therewith is provided, on which a driving shaft roller 34 is provided, on which a driven shaft roller 35 is provided, on which the driving shaft roller 34 and the driven shaft roller 35 are sleeved with abrasive belts 36, on which a polishing motor 321 drivingly connected to the driving shaft roller 34 is provided on the polishing seat 32, and on which a polishing adjustment member for controlling the tightness of the abrasive belt 36 is provided; the polishing adjustment member includes a servo motor 37, on which an adjustment gear 38 is provided, and at the bottom of the adjustment seat 33 four sliding rods 39 are provided, and the four sliding rods 39 are slidably matched with the polishing seat 32, and one of the sliding rods 39 is provided with an adjustment tooth plate 390, and the adjustment gear 38 and the adjustment tooth plate 390 are meshed with each other;

[0028] During grinding, the polishing motor 321 drives the active shaft roller 34 to rotate on the polishing seat 32, which drives the sand belt 36 to rotate on the adjusting seat 33 through the driven shaft roller 35, so that the bottom of the sand belt 36 polishes the surface of the product. The sand belt 36 may become loose after a period of time. During the polishing process, a huge friction force will be generated between the sand belt and the parts. When the sand belt is in a loose state, it will slip. The specific situation can be determined by manual observation. The servo motor 37 is activated by manual control. The conditional gear is driven to slightly raise the sliding rod to achieve fine adjustment, so that the sand belt is always in a tense state to avoid slipping, which affects the polishing effect of the workpiece and prolongs the service life of the sand belt. Preferably, the servo motor 37 is a double-headed motor, and gears are provided at both ends of the motor. There are two sliding rods 39 with adjusting tooth plates 390, which are symmetrically arranged, so that the force is more uniform and the adjustment is more precise.

[0029] In addition, when the sanding belt cannot be used any more and needs to be replaced, the above structure can be used to shorten the distance between the polishing seat and the adjusting seat as much as possible to make the sanding belt loose. After that, the sanding belt can be taken out, and then a new sanding belt can be put on the active shaft roller and the driven shaft roller. Finally, the adjusting component is started to increase the distance between the polishing seat and the adjusting seat so that the new sanding belt is in a taut state. The sanding belt can be replaced without disassembling parts, which is convenient for workers to operate.

[0030] Furthermore, one end of the sliding rod with the adjusting tooth plate is slidably connected to the polishing seat 32. Since the adjusting tooth plate is meshed with the adjusting gear, the sliding rod of the adjusting tooth plate will not slide down under the premise that the adjusting gear does not move. In this embodiment, the other end of the sliding rod of the adjusting tooth plate will not directly contact the adjusting seat 33, but a pressure sensor 5 is provided at the end. The pressure sensor 5 is close to the bottom surface of the adjusting seat 33. Under normal circumstances, the sanding belt is in a taut state, and the force applied by the sanding belt on the driven shaft roller 35 and the adjusting seat 33 will fluctuate within a certain range, that is, the force detected by the pressure sensor 5 will fluctuate within a certain range. When the sanding belt is in a relaxed state, the force applied to the driven shaft roller 35 and the adjusting seat 33 will decrease, that is, the force detected by the pressure sensor 5 will become less.

[0031] Using the above principle, a threshold range is preset in the control system. When the value detected by the pressure sensor 5 is smaller than the threshold range, the control system triggers the servo motor to push the sliding rod slightly up. At this time, the value of the pressure sensor 5 will continue to increase. When the value of the pressure sensor 5 reaches the threshold again, the servo motor stops moving.

[0032] It should be noted that when adjustment is required, the control system should sound an alarm, and then the entire equipment should be stopped. After the adjustment is completed, the sliding rod and the polishing seat 32 can be locked by nuts or the like to fix the relative position.

[0033] In this embodiment, refer to Figure 7 As shown, the milling device 4 includes a second slide 41, the second slide 41 is connected to the moving end of the right movable screw slide 23, the second slide 41 is provided with a second lifting assembly 42, the second lifting assembly 42 is provided with a mounting block 43, the mounting block 43 is provided with a milling motor 44, and the milling motor 44 is provided with a grinding disc 45.

[0034] When cutting the product, the second lifting assembly 42 will drive the grinding disc 45 to move downward to cut the product, and the milling motor 44 will drive the grinding disc 45 to rotate to cut the surface of the product.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
