Abstract
Description
Technical Field
[0001] This utility model relates to the field of flange production technology, and in particular to a grinding device for flange production. Background Technology
[0002] A valve flange, also called a flange plate or flange, is a component used to connect pipes, connecting the ends of pipes. Flanges are also used on equipment inlets and outlets to connect two pieces of equipment, such as gearbox flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts forming a combined sealing structure. Pipe flanges refer to flanges used for piping in pipeline installations, while equipment flanges refer to the inlet and outlet flanges of the equipment.
[0003] A Chinese patent, CN221415977U, describes a valve flange grinding device. It comprises a support frame, a servo motor, grinding wheels, a cylinder, and a limiting assembly. Two grinding wheels are symmetrically arranged. The servo motor drives the two grinding wheels to rotate synchronously, and the cylinder moves the inner ring installed inside retaining rings one and two downwards, simultaneously grinding both end faces of the inner ring and improving the efficiency of flange grinding. Secondly, the cooperation of retaining rings one and two, along with the limiting ring, improves the stability of the inner ring installation. However, using retaining rings one and two, along with the screw, to fix the flange results in time-consuming feeding and unloading when grinding large batches of flanges. Repeatedly disassembling the bolts can easily cause stripping, gradually reducing stability. Therefore, this patent proposes a flange grinding device to solve these problems. Utility Model Content

[0019] like Figure 1-2 As shown, the present invention proposes a grinding device for flange production, comprising a base 1, a frame 2, and two grinding machines 4. The frame 2 is connected to the top of the base 1, and the two grinding machines 4 are arranged opposite each other inside the frame 2. The device is characterized by further comprising a top plate 3 and a fixing frame 6. The top plate 3 is connected between the left and right side walls of the frame 2, and the fixing frame 6 is connected to the top of the top plate 3. A placement block 61 is connected to the top of the fixing frame 6, and clamping frames 62 are hinged to both the front and rear sides of the fixing frame 6. A driving assembly 7 is provided inside the fixing frame 6 to drive the two clamping frames 62 to clamp together. Two moving assemblies 5 are provided at the top of the top plate 3 and drive the two grinding machines 4 to move relative to each other. A fixing assembly 8 is provided at the top of the frame 2.
[0020] In this utility model, the frame 2 is fixedly connected to the top of the base 1. The bottom of the frame 2 is missing. A double door is provided on the front side. The top plate 3 is connected between the left and right walls of the frame 2. The width of the top plate 3 is lower than the width of the frame 3. The fixing frame 6 is fixedly connected to the top of the top plate 3 and is missing on both the front and back sides. The top of the fixing frame 6 is hinged with two clamping frames 62 and a placement block 61. The placement block 61 is located in the middle of the two clamping frames 62. The flange is placed on the placement block 61. The two clamping frames 62 are driven to move closer by the driving component 7 to clamp and fix the flange. At the same time, a fixing component 8 is set at the top of the frame 2 to improve stability. The two grinding machines 4 are moved relative to each other or back to back by the moving component 5 to grind the two sides of the flange. After grinding is completed, the two grinding machines 4 are moved away again by the moving component 5, and the flange is taken out from both sides of the two clamping frames 62. This facilitates the taking and putting of the flange before and after grinding and improves the convenience of flange grinding.
[0021] In an optional embodiment, both clamping frames 62 and the placement block 61 are provided with placement slots, and the two clamping frames 62 are arranged opposite each other.
[0022] In an optional embodiment, the drive assembly 7 includes a first hydraulic cylinder 71, a movable plate 72, and two hinge rods 73.

[0023] In an optional embodiment, the fixing component 8 includes a second hydraulic cylinder 81 and a pressing frame 82. The second hydraulic cylinder 81 is disposed at the top of the frame 2 and the telescopic rod is vertically downward. The pressing frame 82 is connected to the bottom end of the telescopic rod of the second hydraulic cylinder 81.
[0024] It should be noted that the flange is aligned with the placement slot, and then the first hydraulic cylinder 71 is activated to push the moving plate 72 upward. At this time, the two clamping rods 62 are clamped by the two hinge rods 73 to fix the flange. The second hydraulic cylinder 81 is activated to move the pressing frame 82 downward to clamp the top of the flange and improve stability.
[0025] In an optional embodiment, the moving component 5 includes a motor 51 and a bidirectional threaded rod 52. The motor 51 is located on the right side of the frame 2.
