DETAILED DESCRIPTION

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0031] Combination Figures 3 to 5 As shown, an embodiment of the utility model provides a water channel cover plate processing device, including a support plate 4, a pressing portion, a plurality of first positioning plates 5 and a second positioning plate 6.

[0032] The support plate 4 mainly plays a supporting role, and is used to support the pressing part, the first positioning plate 5, the second positioning plate 6 and other components. There are multiple first positioning plates 5 and second positioning plates 6, and the first positioning plates 5 and second positioning plates 6 are arranged on the support plate 4 along the circumferential direction. The first positioning plate 5 is used to position the first waterway cover plate 11, and the second positioning plate is used to position the second waterway cover plate 12. The first waterway cover plate 11 and the second waterway cover plate 12 are not spaced apart from the support plate 4, and the first waterway cover plate 11 and the second waterway cover plate 12 are not coaxial. The pressing part is used to press down and fix the first waterway cover plate 11 and the second waterway cover plate 12.

[0033] The specific number of the first positioning plate 5 and the second positioning plate 6 is set according to actual needs. Since the waterway cover plate is in a circular ring shape before the notch is processed, the first positioning plate 5 and the second positioning plate 6 are arranged in a circle. The first positioning plate 5 and the second positioning plate 6 and the support plate 4 are detachable, which is convenient for quick replacement to adapt to waterway cover plates of different sizes or types. The first positioning plate 5 and the second positioning plate 6 have the function of providing stable support and fixation for the waterway cover plate to prevent displacement during the processing of the waterway cover plate. The first positioning plate 5 and the second positioning plate 6 have a structure adapted to the contour of the waterway cover plate, or the first positioning plate 5 and the second positioning plate 6 are provided with a pin that limits the waterway cover plate. The first positioning plate 5 and the second positioning plate 6 adopt a staggered design and are not coaxial, leaving enough processing space for the milling cutter. The pressing part can use a pressing block, which is detachably connected to the support plate for easy disassembly and installation. The pressing part can also use a hydraulic cylinder to press and loosen the waterway cover plate to reduce the labor intensity of manual disassembly.

[0034] According to the water channel cover plate processing device of the embodiment of the utility model, two groups of positioning plates and a clamping portion are arranged on the support plate. Each group of positioning plates can position one water channel cover plate, thereby preventing each water channel cover plate from moving during the processing and ensuring the processing accuracy. As a result, two water channel cover plates can be processed in one installation and fixing operation, thereby increasing the number of water channel cover plates processed per unit time and improving the processing efficiency.

[0035] In some embodiments, Figure 3As shown, the waterway cover plate processing device also includes a support portion 8, and the support portion 8 is arranged at the bottom of the support plate 4. The support portion 8 can be fixed on the workbench of the milling machine, and the support portion 8 raises the support plate 4, so that the milling cutter processing is smoother. In one example, the support portion 8 includes a heightened plate 81 and a base 82 connected together, the heightened plate 81 is connected to the bottom surface of the support plate 4, and a workbench connecting hole 821 is provided on the heightened plate 81. The heightened plate 81 is fixed to the support plate 4 by bolts, and the height of the heightened plate 81 can be set according to actual needs, and there is no restriction on this. The base 82 is arranged at the bottom of the heightened plate 81 and is fixed to the heightened plate 81 by bolts. The workbench connecting hole 821 is connected to the workbench of the milling machine through bolts.

[0036] In addition, the support plate 4 is provided with a chip removal groove 42 extending from the middle to the edge, which is convenient for the removal of chips from the processing of the waterway cover plate. Optionally, the depth of the chip removal groove 42 gradually increases from the middle to the edge of the support plate 4 to avoid the accumulation of chips and reduce the difficulty of cleaning.

[0037] like Figure 3 As shown, in some embodiments, the first positioning plate 5 is provided with a first curved surface 51 on the side close to the first waterway cover plate 11, and the second positioning plate 6 is provided with a second curved surface 61 on the side close to the second waterway cover plate 12. The center of the first curved surface 51 is concentric with the center of the first waterway cover plate 11, and similarly, the second curved surface 61 is concentric with the center of the second waterway cover plate 12. The first positioning plate 5 and the second positioning plate 6 have positioning surfaces for placing the waterway cover plates horizontally. In one example, the number of the first positioning plate 5 and the second positioning plate 6 are both 5, so that the flatness error of the waterway cover plates is small.

[0038] In some embodiments, Figure 3 As shown, the clamping part is a corner cylinder 7. The corner cylinder is a special hydraulic actuator designed to realize the rotation or swinging movement of an object, and often has a clamping function to complete the positioning and clamping of complex angles in a small space. The corner cylinder 7 is arranged on the support plate 4. The corner cylinder 7 includes a cylinder body 71, a piston rod 72 and a pressure plate 73. One end of the piston rod 72 is arranged inside the cylinder body 71, and the other end of the piston rod 72 is connected to the middle of the pressure plate 73. The two ends of the pressure plate 73 are used to clamp the first waterway cover plate 11 and the second waterway cover plate 12 respectively. When the piston rod 72 is in the maximum extended state, the pressure plate 73 points to the left and right direction of the support plate 4. During the retraction process of the piston rod 72, the rotation of the piston rod 72 drives the pressure plate 73 to point to the front and back direction of the support plate 4, and finally clamps the waterway cover plate.

[0039] In one example, pressure blocks are provided at both ends of the pressure plate 73. The pressure blocks can be made of nylon, and the pressure blocks are connected to the pressure plate 73 by bolts. Nylon has good wear resistance and self-lubrication, and can absorb and alleviate mechanical vibration. The pressure blocks can ensure that the water channel cover plate does not rotate during processing, and also ensure that the water channel cover plate is not crushed.

[0040] In one example, there are three corner oil cylinders 7, two of which are arranged on the left and right sides of the chip groove 42, and the remaining corner oil cylinder 7 is arranged on the rear side of the support plate 4 away from the chip groove 42. The chip groove 42 is above the notch of the water channel cover plate, and the corner oil cylinders on the left and right sides of the chip groove 42 can provide stable support and fixation for the water channel cover plate to ensure the accuracy of processing.

[0041] The inventors found that the inner ring of the prior art waterway cover plate is not positioned during processing, which is prone to deformation (the waterway cover plate is thin), resulting in the waterway cover plate being unable to be effectively assembled with the inner shell and the outer shell. In order to prevent the waterway cover plate from being deformed in the radial direction during processing, the first positioning plate 5 and the second positioning plate 6 located on both sides of the chip groove 42 are provided with limiting columns 20. The limiting columns 20 and the adjacent arc surface clamp the waterway cover plate therein, and the waterway cover plate cannot move radially, so that the processing size is qualified.

[0042] An oil passage is provided in the support plate 4, and the oil passage is connected to the oil port of the corner oil cylinder 7. A solenoid valve can be provided outside the waterway cover plate processing device to control the extension and retraction of the corner oil cylinder 7. A pressure gauge 9 is also provided on the support plate 4, and the pressure gauge 9 is used to display the oil pressure so that the corner oil cylinder 7 works within a suitable pressure range.

[0043] In some embodiments, Figure 5 As shown, the waterway cover plate processing device further includes a lifting ring 10, which is arranged on the support plate 4. The support plate 4 is provided with lifting ring connection holes 41 around it, and the bottom of the lifting ring 10 has an external thread, which can be screwed into the lifting ring connection hole 41. The lifting ring 10 facilitates the movement and transportation of the waterway cover plate processing device.
