DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-3 A valve flange grinding device mechanism for valve processing in this embodiment includes a grinding machine 1 and a grinding wheel 4. A processing table 2 and a working bin 5 are arranged on the top of the grinding machine 1. A valve flange 3 is arranged on the top of the processing table 2.

The valve flange 3 is located on the top of the processing table 2, and the grinding wheel 4 is located directly above the valve flange 3.

[0021] By adopting the above technical solution, the three-phase motor 69 is started and the control rod 67 is driven to rotate, thereby controlling the movement of the two clamps 65, so that the positions of the two clamps 65 are adapted to the positions of the holes of the valve flange 3, thereby facilitating the insertion of the clamps 65 into the holes inside the valve flange 3, and the feed assembly 66 is used to control the positioning strip in the clamp 65 to move to one side, so that the hole positions of the valve flange 3 are fixed by the two positioning strips in the clamp 65, thereby fixing the two positions of the valve flange 3 by the two clamps 65, realizing fast and automatic positioning of valve flanges 3 of different sizes, thereby reducing the labor intensity of the staff.

[0022] In this embodiment, a mounting groove 61 is provided inside the processing table 2, and two connecting blocks 62 are slidably installed inside the mounting groove 61. A mounting frame 63 is fixedly installed on the top of the two connecting blocks 62. A limiting component 64 for limiting the moving trajectory of the two mounting frames 63 is provided on the rear side wall of the inner cavity of the mounting groove 61. The limiting component 64 includes a limiting strip and two limiting grooves. The limiting groove is provided on the back of the mounting frame 63. The limiting strip is fixedly installed on the rear side wall of the inner cavity of the mounting groove 61. The outer surface of the limiting strip is slidably connected to the inner wall of the limiting groove to limit the mounting frame. 63 can only move left and right on the outer surface of the limit bar. A clamp 65 with one end passing through and extending to the outside of the processing table 2 is arranged inside the two installation frames 63. The two clamps 65 include two positioning strips. The positioning strip is fixedly installed on the top of the connecting block 62, and the other positioning strip is slidably installed inside the installation frame 63. One end of the two positioning strips passes through the inside of the valve flange 3, so that the two positioning strips in the clamp 65 can be used to position a part of the valve flange 3. A feed assembly 66 for controlling the clamp 65 is arranged on the two installation frames 63.

[0023] Among them, the two feeding components 66 both include an electric push rod and a circular groove. The circular groove is opened on the installation frame 63, and the electric push rod is fixedly installed on the circular groove. The telescopic end of the electric push rod is fixedly connected to one side of the positioning bar, which is convenient for controlling a positioning bar in the clamp 65 to move left and right.

[0024] By adopting the above technical solution, it is possible to control the two connecting blocks 62 to move to opposite sides, so that the movable connecting block 62 drives the clamp 65 to move through the mounting frame 63 until the distance between the two clamps 65 matches the distance between the internal holes of the valve flange 3, and then the valve flange 3 is sleeved on the two clamps 65, and the electric push rod in the feed assembly 66 is started to control the movement of a positioning bar in the clamp 65, so that the position of a hole in the valve flange 3 is fixed by using the two positioning bars, so that the two clamps 65 can be used to position valve flanges 3 of different sizes.

[0025] In this embodiment, a control rod 67 with one end penetrating through and extending to the outside of the processing table 2 is rotatably installed between the left and right side walls of the inner cavity of the installation groove 61, and two connecting blocks 62 are both threadedly installed on the outer surface of the control rod 67.

One end of the control rod 67 is fixedly connected to a three-phase motor 69, and one side of the processing table 2 is fixedly connected to a mounting frame 68 connected to the outer surface of the three-phase motor 69.

[0026] By adopting the above technical solution, the three-phase motor 69 on the starting mounting frame 68 is realized, so that the three-phase motor 69 drives the screw rod in the control rod 67 to rotate, thereby causing the two connecting blocks 62 threadedly connected on the outer surface of the control rod 67 to move to the opposite side.

[0027] The working principle of the above embodiment is:

[0028] When the valve flange grinding device mechanism for valve processing is used, the three-phase motor 69 on the mounting frame 68 is started, so that the three-phase motor 69 drives the screw rod in the control rod 67 to rotate, thereby making the two connecting blocks 62 threadedly connected on the outer surface of the control rod 67 move to the opposite side, so that the moving connecting block 62 drives the clamp 65 to move through the mounting frame 63 until the distance between the two clamps 65 is matched with the distance between the internal holes of the valve flange 3, and then the valve flange 3 is sleeved on the two clamps 65, and the electric push rod in the feed assembly 66 is started to control the movement of a positioning bar in the clamp 65, so that the position of a hole in the valve flange 3 is fixed by using the two positioning bars, so that the two clamps 65 can be used to position valve flanges 3 of different sizes.
