DETAILED DESCRIPTION

[0024] This specific embodiment is a gearbox accessory hole grinding device, and its structural schematic diagram is as follows Figure 1-Figure 6As shown, it includes a support seat 1, which is L-shaped. A positioning block 2 is fixedly connected to the end face of the support seat 1. A limiting groove 3 is provided on the top face of the support seat 1. A workpiece 4 is mounted on the positioning block 2. A secondary fixing component is provided in the limiting groove 3. A cylinder 5 is fixedly installed on the support seat 1. A pressure plate 6 is fixedly connected to the output end of the cylinder 5. The pressure plate 6 is against the workpiece 4. Slots 11 are respectively provided on the left and right side walls of the support seat 1 near the bottom surface, and a connecting component is provided in the slot 11.

[0025] Specifically, the support seat 1 is used in conjunction with the connecting assembly and is installed on a processing table of a machine tool, and the number of the support seats 1 can be determined according to actual processing requirements.

[0026] like Figure 2 and Figure 4 As shown, the secondary fixing assembly includes a top plate 7 arranged in the limiting groove 3, and a receiving hole 9 is opened near the top surface of the front side wall of the support seat 1. A screw 8 is threadedly connected to the receiving hole 9, and the other end of the screw 8 is rotatably connected to the top plate 7, and the top plate 7 is against the workpiece 4.

[0027] Among them, after the workpiece 4 is assembled, the screw 8 can be driven to rotate by using an Allen wrench to drive the top plate 7 to move, and the grinding position of the workpiece 4 is reinforced for the second time to ensure that the accuracy of the workpiece 4 after grinding meets the processing technical requirements.

[0028] like Figure 1 and Figure 3 As shown, the connecting assembly includes two connecting plates 12 arranged in the slot 11. The top surfaces of the two connecting plates 12 are each provided with a long hole, and bolts 13 are provided in the long holes. Nuts 14 are threadedly connected to the bolts 13, and the same pad 15 is provided on the lower side of the two connecting plates 12 on the same side.

[0029] Specifically, the bottom end of the bolt 13 is a hexagonal block, which is easy to insert into the T-slot on the processing table, and plays a role in installing and fixing the support seat 1. The pad 15 is used to fill the gap generated by the connecting plate 12, so that the bolt 13 has better stability after being tightened.

[0030] like Figure 1 and Figure 6 As shown, a limiting rod 16 is fixedly connected to the top surface of the support seat 1, and the top end of the limiting rod 16 passes through the pressing plate 6 and is movably connected thereto.

[0031] When the cylinder 5 drives the pressing plate 6 to move up and down, the limiting rod 16 can be used to keep the pressing plate 6 in a stable operating state, and the workpiece 4 is pressed at the same position each time, which effectively clamps and fixes the workpiece 4.

[0032] like Figure 2 and Figure 4As shown, a guide groove 10 is provided on the bottom surface of the limit groove 3, and the guide groove 10 passes through the support seat 1. The guide groove 10 is located below the processing position of the workpiece 4. When the workpiece 4 is being processed, the cutting fluid or cooling oil sprayed by the machine tool can flow out through the guide groove 10, increasing the reflux speed of the cooling oil.

[0033] like Figure 1 As shown, a positioning groove 17 is provided on the top surface of the support base 1 at the corner.

[0034] The main function of the positioning groove 17 is to support and position the tail end of the workpiece 4 to prevent the tail end of the workpiece 4 from shaking during processing.

[0035] Working principle: First, clamp the workpiece 4 on the positioning block 2, and place the other end of the workpiece 4 in the limit groove 3. Then start the cylinder 5 to drive the pressure plate 6 to move downward to press the workpiece 4. Then, turn the screw 8 with the Allen wrench. The screw 8 drives the top plate 7 to press against the side wall of the workpiece 4 to reinforce the grinding position. Then, run the machine tool to grind the hole position of the workpiece 4 to achieve the purpose of efficient and accurate grinding of sheet metal parts.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
