Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a mechanical processing grinding device. Background Art

[0002] Grinding machines, also known as polishing machines, are often used for mechanical grinding, polishing and waxing. They use electric motors to drive the sponge or wool polishing disk installed on the polishing machine to rotate at high speed, and rub the surface of the workpiece to remove paint pollution, oxide layer and shallow marks.

[0003] During mechanical processing, a grinding device is often required to grind the outer surface of a workpiece. The grinding device in the prior art usually requires a screw to squeeze and position the top of the workpiece when grinding the workpiece, so that the workpiece contacts the grinding disc, and then the polishing disc is controlled to rotate for grinding. Since the screw needs to be rotated multiple times each time the workpiece is positioned, it is more laborious to position the workpiece. Therefore, after processing one group of workpieces, it is not convenient to quickly replace the workpieces, which affects the processing efficiency of the workpieces. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-5 As shown, the utility model provides a mechanical processing grinding device, including a grinding machine table 1, a driving device 2 is arranged on the top of the grinding machine table 1, a rotating shaft 3 is installed on the output shaft of the driving device 2, and a material tray 4 is installed on the bottom end of the rotating shaft 3, and also includes:

[0026] A positioning structure, which is arranged on the rotating shaft 3 and is used for quickly positioning and disassembling the workpiece;

[0027] Among them, the positioning structure includes a fixed plate 5, which is sleeved on the outer surface of the rotating shaft 3, and a positioning shaft 6 is sleeved inside the fixed plate 5. A baffle 7 is installed on the top of the positioning shaft 6, and a return spring 8 is sleeved on the outer surface of the positioning shaft 6. A baffle 7 is installed on the top of the positioning shaft 6, and a slide groove 9 is provided on the top of the baffle 7. A fixed plate 10 is installed on one side of the rotating shaft 3, and a fixed shaft 11 is installed inside the fixed plate 10. A ratchet 12 is installed on the outer surface of the fixed shaft 11. An extrusion piece 13 is sleeved on the outer surface of the fixed shaft 11, and a notch 14 is provided inside the extrusion piece 13. A fixing rod 15 is installed inside the notch 14, and a claw 16 and a first spring 17 are sleeved on the outer surface of the fixing rod 15.

[0028] Through the cooperation between the fixed shaft 11 and the extrusion piece 13, the extrusion piece 13 can rotate along the outer surface of the fixed shaft 11. At this time, the bottom end of the extrusion piece 13 will slide along the inner side of the slide groove 9 and squeeze the slide groove 9, so that the baffle 7 drives the positioning shaft 6 to move downward along the inner side of the fixed plate 5, so that the workpiece can be positioned through the bottom end of the positioning shaft 6. At the same time, through the elastic force of the first spring 17, it will move along the outer surface of the fixed rod 15 through the claw 16, and then the extrusion piece 13 can be positioned through the cooperation between the claw 16 and the ratchet 12, so as to facilitate the rapid positioning or disassembly of the workpiece.

[0029] like Figure 3 As shown, a movable frame 18 is sleeved inside the material tray 4, a second spring 19 is sleeved on the outer surface of the movable frame 18, a clamping block 20 is installed at one end of the movable frame 18, a connecting rod 21 is installed on the top of the clamping block 20, and a rotating block 22 is threadedly connected to the outer surface of the rotating shaft 3.

[0030] Through the cooperation between the rotary block 22 and the rotating shaft 3, the rotary block 22 can move up and down along the outer surface of the rotating shaft 3. At the same time, through the cooperation between the movable frame 18 and the material tray 4, when the rotary block 22 squeezes the connecting rod 21, the movable frame 18 will be driven by the clamping block 20 to move along the inner side of the material tray 4, thereby driving the clamping block 20 to contact the workpiece, thereby facilitating the placement of workpieces of different sizes on the material tray 4.

[0031] like Figure 5 As shown, one side of the claw 16 is provided with a chamfer, and the claw 16 is movably engaged with the ratchet 12 .

[0032] By setting a chamfer on one side of the claw 16, when the claw 16 rotates downward, the beveled edge of the claw 16 will be squeezed with the beveled edge of the ratchet 12. At this time, the claw 16 will move along the outer surface of the fixing rod 15, so that the downward rotation of the extrusion member 13 will not be affected, and at the same time, the upward rotation of the extrusion member 13 can be restricted.

[0033] like Figure 1 , 5 As shown, the first spring 17 is elastically supported between the claw 16 and the notch 14 , and the return spring 8 is elastically supported between the baffle 7 and the fixed disk 5 .

[0034] Through the design of the first spring 17, the claw 16 has good elastic reset performance. At this time, since the first spring 17 is in a compressed state, an elastic force will be applied to the claw 16, so that the fit between the claw 16 and the ratchet 12 is tighter. Through the design of the reset spring 8, the baffle 7 has good elastic reset performance. At this time, since the reset spring 8 is in a compressed state, an elastic force will be applied to the baffle 7. Therefore, when the extrusion member 13 releases the extrusion on the slide groove 9, the positioning shaft 6 will be driven to separate from the workpiece through the baffle 7, which is convenient for disassembly of the workpiece.

[0035] like Figure 1 As shown, the bottom of the extrusion member 13 is slidably matched with the slide groove 9 and is in extrusion contact with the slide groove 9, and one side of the baffle 7 is in contact with the rotating shaft 3.

[0036] Through the cooperation between the extrusion piece 13 and the slide groove 9, when the extrusion piece 13 squeezes the slide groove 9, it will drive the baffle 7 to move downward. At the same time, since one side of the baffle 7 is in contact with the rotating shaft 3, the baffle 7 can be prevented from rotating, making it more stable.

[0037] like Figure 3 As shown, the bottom of the rotary block 22 is conical, and the rotary block 22 is in compression contact with the connecting rod 21 .

[0038] Due to the conical design of the bottom of the rotary block 22 , when the rotary block 22 presses the connecting rod 21 , the clamping block 20 will be driven to move through the connecting rod 21 , thereby driving the clamping block 20 to press the outer side of the workpiece.

[0039] like Figure 3 As shown, the second spring 19 is elastically supported between the movable frame 18 and the slot 14 .

[0040] Through the design of the second spring 19, the movable frame 18 has good elastic reset performance. At this time, due to the design of the second spring 19, the movable frame 18 has good elastic reset performance. At this time, since the second spring 19 is in a compressed state, it will apply an elastic force to the clamping block 20, thereby driving the clamping block 20 to separate from the outer side of the workpiece.

[0041] Working principle:

[0042] First, the staff places the workpiece on the material tray 4, and then presses the extrusion piece 13 to rotate along the outer surface of the fixed shaft 11 through the cooperation between the fixed shaft 11 and the extrusion piece 13. At this time, the bottom end of the extrusion piece 13 will slide along the inner side of the slide groove 9 and squeeze the slide groove 9, so that the baffle 7 drives the positioning shaft 6 to move downward along the inner side of the fixed plate 5, so that the workpiece can be positioned through the bottom end of the positioning shaft 6. At the same time, through the elastic force of the first spring 17, it will move along the outer surface of the fixed rod 15 through the claw 16, and then the extrusion piece 13 can be positioned through the cooperation between the claw 16 and the ratchet 12, so as to facilitate the rapid positioning or disassembly of the workpiece.
