[0041] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0042] The utility model provides a grinding device for cast iron gate production, according to the attached manual Figure 1 To Attachment Figure 4 It can be seen that a grinding device for cast iron gate production mainly includes the following parts or components: a processing base 10, a moving seat 30, a first screw 34, a moving plate 36, and a pressing plate 38. The connection relationship of each part or component is as follows:

[0043] A support seat 11 is provided on one side of the processing base 10, and a rotating shaft 12 is vertically provided at the bottom of the support seat 11. After the rotating shaft 12 is connected to and penetrates the rotating shaft of the processing base 10, it is connected to the driving component on the processing base 10 to drive the rotating shaft 12 to rotate; a moving seat 30 is provided on the processing base 10 on one side of the support seat 11, and is slidably connected to a first guide rod 31 horizontally provided on the processing base 10, a first motor 32 is provided on the moving seat 30, and a grinding disc 33 is provided at the output end of the first motor 32; a first screw 34 is provided parallel to the first guide rod 31 on the processing base 10, and rotates under the drive of the second motor 35, the first screw 34 is threadedly connected to and penetrates the movable seat 30; the two movable plates 36 are symmetrically arranged on the support seat 11, and are slidably connected to the support seat 11. The adjustment component 40 arranged on the support seat 11 is used to drive the two movable plates 36 to move closer to or away from each other, and support plates 37 are arranged on opposite sides of the two movable plates 36; second guide shafts 39 are respectively arranged on the upper ends of the two pressing plates 38, and after the second guide shafts 39 are slidably connected to and penetrate the corresponding support plates 37, they are connected to the clamping mechanism 50 to drive the pressing plates 38 to rise and fall.

[0044] After placing the cast iron gate on the support seat 11, the positions of the two movable plates 36 are adjusted by the adjustment component 40, so that the two pressure plates 38 can fix the cast iron gates of different sizes under the action of the clamping mechanism 50, and then the driving component drives the support seat 11 to rotate so that the polished surface of the cast iron gate is parallel to the first guide rod 31. Finally, the first motor 32 is started to make the polishing disc 33 polish the side of the cast iron gate, and during the polishing process, the second motor 35 drives the first screw 34 to rotate, thereby driving the polishing disc 33 to polish the side of the cast iron gate, which greatly improves the polishing efficiency, and the side of the cast iron gate has high flatness and good polishing quality.

[0045] After grinding one side of the cast iron gate, the support seat 11 can be driven to rotate by the driving assembly to make the other side of the cast iron gate close to the grinding disk 33. The cast iron gate can be ground by the grinding disk 33 without frequent assembly and disassembly, reducing manual labor intensity and effectively improving grinding efficiency.

[0046] As an embodiment, according to the attached Figure 2 It can be seen that two first slideways 13 are arranged in parallel on the support seat 11, and a slider 14 is slidably connected in each first slideway 13, and the two sliders 14 are respectively connected to the two moving plates 36. The sliding of the slider 14 in the slideway can provide precise linear guidance for the moving plate 36, reduce deviation and shaking, and ensure that the moving plate 36 moves smoothly and stably along the preset direction.

That is, when the worm 22 stops rotating, the turbine 21 is difficult to reverse due to the particularity of the tooth profile of the worm 22, which has a good effect on maintaining the position stability of the support seat 11, and the transmission of the worm gear 22 has a higher transmission accuracy, a smaller transmission error, and a more accurate adjustment of the direction of the polished surface of the cast iron gate, so that the polished surface is parallel to the first guide rod 31, which is more convenient for the polishing disc 33 to polish the cast iron gate.

[0050] In this embodiment, the third motor 23 is a servo motor, which can realize closed-loop control of position, speed and torque, thereby achieving high control accuracy, running very smoothly, almost without jitter, and maintaining constant torque output to prevent the device from shaking.

[0052] When the fourth motor 52 drives the first transmission shaft 51 to rotate, the second guide shaft 39 can be driven to rise and fall through the crank 53 and the hinge rod 54. When the pressure plate 38 descends, the pressure plate 38 can fix the cast iron gate. On the contrary, when the pressure plate 38 rises, the cast iron gate can be conveniently taken and placed, with good fixing effect and convenient taking and placing.

[0054] When the two movable plates 36 move relative to each other, the second transmission shaft 551 will slide in the guide sleeve. When one of the cranks 53 rotates, the other crank 53 can be driven to rotate under the action of the guide sleeve, the guide key 552 and the guide groove 554 on the second transmission shaft 551, without causing motion interference, thereby ensuring that the clamping mechanism 50 can operate normally.

[0055] As an embodiment, according to the attached Figure 1 It can be seen that the second hydraulic cylinder 60 is arranged on the movable seat 30, and the piston rod end of the second hydraulic cylinder 60 is connected to the first motor 32.
