DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-8 As shown, a polishing device for metal accessories includes a workbench 1 and a polishing machine body 2, and a quick clamping device is installed on the lower side of the polishing machine body 2;

[0026] A number of circular holes 3 are evenly arranged on the upper side of the workbench 1, and a number of left-right oriented transverse grooves 4 are spaced apart on the lower side of the circular hole 3, and the transverse grooves 4 match the semicircle on the rear side of the circular hole 3. The clamping device includes a clamping block group, and the clamping block group includes a number of left-right oriented clamping blocks 5, the width of the clamping block 5 is smaller than the width of the transverse groove 4, and a number of arc grooves 6 are arranged on the front side of the clamping block 5, and the arc groove 6 matches the circular hole 3 and the depth of the arc groove 6 is smaller than the radius of the circular hole 3. Slide bars 7 are installed on the left and right lower sides of the workbench 1, and the clamping block group is connected to the slide bar 7 for forward and backward sliding. A clamping column 8 matching the circular hole 3 is vertically slidably installed on the inner side of the circular hole 3, and a baffle 9 larger than the diameter of the circular hole 3 is fixed on the lower side of the clamping column 8, and a spring 10 is installed on the lower side of the baffle 9, and the lower side of the spring 10 abuts against the inside of the workbench 1, and a control component is installed on the front side of the workbench 1, and the control component is transmission-connected to the clamping block 5, and a flush component is also provided on the lower side of the clamping column 8.

[0027] When the clamping device is not in use, the spring 10 is in an extended state, the clamping column 8 can slide freely up and down inside the circular hole 3, and the height of the clamping column 8 is higher than the height of the workbench 1. When the metal accessories need to be polished, the metal accessories are placed on the workbench 1, and the metal accessories will press the clamping column 8 located on the lower side of the metal accessories into the circular hole 3 of the workbench 1. At this time, the transmission assembly can control the clamping block group to slide forward, and the arc groove 6 on the front side of the clamping block 5 abuts against the clamping column 8, and the metal accessories are clamped by the clamping column 8 located on the side of the metal accessories.

[0028] When encountering thinner metal accessories, the flush component can move the clamping column 8 downward, lower the clamping column 8 on the outside of the metal accessory, and make the clamping column 8 lower than the side of the metal accessory that needs to be polished, making it easier for the polishing machine to polish it. At the same time, the flush component can also move all the clamping columns 8 downward to make them flush with the upper side of the workbench 1.

[0029] The cooperation between the clamping block 5 and the clamping column 8 enables block-shaped metal accessories of any shape to be quickly fixed by the clamping device, thereby improving the overall polishing efficiency of the polishing device. The leveling device adjusts the clamping device to form a plane with the workbench 1 as a whole, which is convenient for cleaning the chips generated by the polishing of metal accessories. The spring 10 facilitates the resetting of the clamping column 8 after use, and the baffle 9 limits the clamping column 8.

[0030] A through hole 24 is horizontally opened in the middle of the front side of the workbench 1, and the control component includes a rotating shaft rod 11. Several clamping blocks 5 are transmission-connected to the rotating shaft rod 11. A thread 12 is provided on the front side of the rotating shaft rod 11, and the thread 12 is connected to the thread 12 of the workbench 1. A handle 13 is installed on the front side of the rotating shaft rod 11.

[0031] When the clamping column 8 needs to be fixed, since the shaft rod 11 is connected to the workbench 1 through the thread 12, the control handle 13 rotates the shaft rod 11, and the shaft rod 11 can drive the clamping block 5 to move forward to fix the machine column.

[0032] The cooperation between the clamp block 5 and the rotating shaft rod 11 makes the control component simple in structure and more reliable, and also makes it easier for the staff to debug and use the control component.

[0033] The flush assembly includes a perforated plate 14, a plurality of small holes are opened on the upper side of the perforated plate 14 and the small holes are sleeved on the outside of the clamping column 8, and the perforated plate 14 is located on the upper side of the baffle 9, and the diameter of the small holes is smaller than the diameter of the baffle 9. A limit block 15 fixedly connected to the inner wall of the workbench 1 is installed on the lower side of the perforated plate 14, a cross bar is hinged on the lower side of the workbench 1, a foot control pedal 22 is fixed on the front side of the cross bar, and a pull wire 16 transmission-connected to the perforated plate 14 is installed on the upper side of the foot control pedal 22.

[0034] When the flush assembly is needed, the staff only needs to step on the foot control pedal 22 downward, and the pull wire 16 can pull the orifice plate 14 to drive the clamping column 8 to descend. When the orifice plate 14 abuts against the limit block 15, the clamping column 8 can be flush with the top of the workbench 1. When the foot control pedal 22 is released, the spring 10 can make the orifice plate 14 pull the foot control pedal 22 to return to its original position.

[0035] The foot control pedal 22 allows the staff to control the lifting and lowering of the clamping column 8 with their feet. The foot control pedal 22 can free the hands, allowing the user to carry out other activities while controlling the equipment.

[0036] The top and rear sides of the workbench 1 are equipped with enclosures 17, the right side of the workbench 1 is equipped with a collecting funnel 18, and the lower side of the collecting funnel 18 is equipped with a discharge hopper 19.

[0037] The enclosure 17 can block the waste chips generated when the polishing machine body 2 polishes the metal parts to prevent the waste chips from splashing. The collecting funnel 18 can collect the waste chips generated on the upper side of the workbench 1 and guide them to the right to be discharged through the discharge hopper 19.

[0038] Furthermore, a waste box can be placed under the discharge hopper 19 to collect waste chips.

[0039] A control valve 20 is installed on the left side of the workbench 1 , and a plurality of air nozzles 21 linearly distributed frontward and rearward are connected to the right side of the control valve 20 .

[0040] The control valve 20 is connected to an external air pump. The control valve 20 can control the air nozzle 21 to blow air to the upper side of the workbench 1. The air nozzle 21 blows the waste chips on the upper side of the workbench 1 to the inside of the collecting funnel 18, which is convenient for automatic cleaning of the workbench 1 when the top of the clamping column 8 is flush with the workbench 1, thereby improving ease of use.

[0041] A controller 23 is installed on the side of the foot control pedal 22 and is transmission-connected to the foot control pedal 22 . The controller 23 is electrically connected to the control valve 20 .

[0042] When the foot pedal 22 moves to the lowest stroke, the controller 23 can be triggered to control the control valve 20 to supply air to the air nozzle 21. At this time, the top of the clamping column 8 is flush with the workbench 1.

[0043] The controller 23 can automatically control the control valve 20 when the top of the clamping column 8 is flush with the workbench 1, thereby improving the simplicity of operation.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
