Description

Technical Field

[0002] Ring plates can be used in gates, pipe connections and other parts of water conservancy equipment to withstand water flow impact and water pressure to ensure the safe operation of water conservancy facilities. During the processing and manufacturing process of the ring plate, the blank is first manufactured through flame cutting and welding. However, the dimensional tolerance and surface quality of the original blank cannot meet the design requirements. In this case, a milling machine is generally used for surface cutting. However, when the ring plate is large in size, using a milling machine to process the surface of the ring plate will increase the swing arc of the milling cutter. The increase in the swing arc of the milling cutter can easily reduce the stability of the milling cutter during the processing, thereby reducing the processing accuracy and processing quality.

[0023] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0024] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0025] This embodiment provides a processing device, referring to Figures 1 to 3 , including a rotating table 1, the rotating table 1 can rotate around its own axis, the rotating table 1 is arranged in the ring plate 2 and is coaxially arranged therewith, a connecting mechanism 3 is installed on the top of the rotating table 1, the connecting mechanism 3 is extended along the radial direction of the rotating table 1, one end of the connecting mechanism 3 is provided with a processing mechanism 4 for processing the annular surface of the ring plate 2, and the other end is provided with a stress applying mechanism for applying stress to the connecting mechanism 3. When the device is working, the rotation of the rotating table 1 will drive the connecting mechanism 3 to rotate, so that the motion trajectory of the processing mechanism 4 installed on the connecting mechanism 3 is circular shape, thereby realizing the processing of the annular surface of the ring plate 2. It can be understood that since the processing mechanism 4 is provided at one end of the connecting mechanism 3, the weight distribution at both ends of the connecting mechanism 3 is uneven, and the structural stability of the connecting mechanism 3 cannot be guaranteed, resulting in the connecting mechanism 3 may shake or shake during the rotation process, thereby affecting the processing quality. A stress applying mechanism is provided at the other end of the connecting mechanism 3. The stress applying mechanism can apply downward stress to the connecting mechanism 3, can adjust the center of gravity position of the connecting mechanism 3, ensure the stability of the connecting mechanism 3 during rotation, and help improve the processing accuracy and quality. In this embodiment, the rotary table 1 is a structure with its own power source, such as a structure driven by a power device such as a hydraulic motor or an electric motor to rotate.

[0026] Specifically, the connecting mechanism 3 is horizontally installed on the top surface of the rotating worktable 1, and the vertical projection of the part of the connecting mechanism 3 that is used to install the processing mechanism 4 and extends outward from the rotating worktable 1 exceeds the outer edge of the ring plate 2, thereby ensuring that the processing mechanism 4 arranged on the connecting mechanism 3 can always realize the processing of the annular surface of the ring plate 2.

[0027] Furthermore, in order to improve the applicability of the device and enable the device to process the annular surfaces of ring plates 2 with different diameters, a first driving mechanism that is transmission-connected to the processing mechanism 4 is provided on the connecting mechanism 3. The first driving mechanism can drive the processing mechanism 4 to move repeatedly along the axial direction of the connecting mechanism 3, thereby changing the position of the processing mechanism 4 on the connecting mechanism 3, so that the processing mechanism 4 can process the annular surfaces of ring plates 2 with different diameters.

[0028] Furthermore, in order to ensure the accuracy of the movement of the processing mechanism 4 and improve the processing accuracy, the first driving machine is set to a screw motor 6. The screw motor 6 can realize precise control and positioning of the transmission components. Specifically, the screw motor 6 includes a motor 61 and a screw 62. The screw 62 is connected to the processing mechanism 4 through the transmission component, and the screw 62 is extended along the axial direction of the connecting mechanism 3. When the screw motor 6 is working, the motor 61 drives the screw 62 to rotate, so that the processing mechanism 4 set on the screw 62 can move linearly along the extension direction of the screw 62, thereby realizing accurate adjustment of the position of the processing mechanism 4, which helps to improve the processing accuracy and quality.

[0029] In this embodiment, the connecting mechanism 3 includes two support members 31 arranged relatively at an interval, and the support members 31 are detachably connected to the top of the rotating worktable 1 through fasteners 7. A first connecting member 33 and a second connecting member 34 are connected between the two support members 31. The first connecting member 33 and the second connecting member 34 are arranged at an interval. The motor 61 is arranged on the first connecting member 33, and the end of the screw 62 away from the motor 61 is installed on the second connecting member 34. This is not only convenient for installation, but also ensures the normal operation of the screw motor 6.

[0030] At the same time, two symmetrical sliding grooves 32 are respectively provided on the two supporting members 31. The extension direction of the sliding grooves 32 is the same as the extension direction of the connecting mechanism 3. The two sides of the processing mechanism 4 are slidingly connected with the two sliding grooves 32 respectively. The provision of the sliding grooves 32 can, on the one hand, ensure that the processing mechanism 4 can always move along the axial direction of the connecting mechanism 3 under the drive of the screw motor 6. On the other hand, the sliding grooves 32 also play a supporting role for the processing mechanism 4, which helps to reduce the load borne by the screw motor 6, thereby improving the service life of the screw motor 6.

[0031] In this embodiment, the processing mechanism 4 includes a mounting frame 42 and a processing assembly 41. The lead screw 62 is connected to the mounting frame 42. Both sides of the mounting frame 42 are provided with sliding parts 421 that slide with the slide groove 32. The processing assembly 41 includes a driving member 411 and a milling cutter 412. The driving member 411 can drive the milling cutter 412 to rotate. During the actual processing, the milling process of the outer surface of the ring plate 2 is achieved by contacting the outer surface of the ring plate 2 with the high-speed rotating milling cutter 412.

[0032] In this embodiment, the stress applying mechanism is configured as a counterweight 5, which has a certain mass. The counterweight 5 is detachably connected to the end of the connecting mechanism 3 away from the processing mechanism 4 so that the counterweight 5 can change the center of gravity position of the connecting mechanism 3, ensuring that its mass distribution in all directions is uniform, thereby improving the stability of the connecting mechanism 4 structure, and the mass of the counterweight 5 can be changed according to the position of the processing mechanism 4.

[0033] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
