DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figure 1 — Figure 3 As shown, this embodiment discloses a mechanical component surfacing repair auxiliary device, including a support frame 1, a protective cover 2 is arranged in the middle of the support frame 1, a collecting box 3 is arranged at the lower part of the protective cover 2, a mounting mechanism 4 is arranged in the middle of the inner cavity of the protective cover 2, the mounting mechanism 4 is rotatably mounted on the upper end of the support frame 1, fixing devices 5 are arranged on both sides of the inner cavity of the mounting mechanism 4, a transmission device 6 is arranged on one side of the outer surface of the mounting mechanism 4, and the transmission device 6 is fixedly mounted on one side of the upper end of the support frame 1.

[0036] Specifically, when performing surfacing welding repair on mechanical components, a certain amount of waste will be generated, and the waste will fall into the inner cavity of the protective cover 2. After the repair is completed, the staff can sweep the waste that has fallen into the inner cavity of the protective cover 2 into the inner cavity of the collection box 3 for collection. When a certain volume of waste is collected in the inner cavity of the collection box 3, the staff can remove the collection box 3 from the lower part of the protective cover 2, and then the staff can process the waste in the inner cavity of the collection box 3.

[0037] Before welding repair of mechanical components, the mechanical components need to be fixed on the auxiliary device so that the staff can perform welding repair on the mechanical components. In order to enable the auxiliary device to fix mechanical components of different sizes, such as Figure 4As shown, the mounting mechanism 4 includes a mounting ring 41, and connecting plates 42 are provided on both sides of the outer surface of the mounting ring 41. The connecting plate 42 on the side away from the transmission device 6 is rotatably installed on the upper end of the support frame 1, and a fixing hole array is provided on the lower part of the outer surface of the connecting plate 42. Two limit plates 43 are provided on the side of the outer surfaces of the two connecting plates 42 close to each other. The four limit plates 43 are respectively slidably connected to the upper and lower ends of the mounting ring 41, and two limit holes are provided in the middle of the two limit plates 43 located on the side close to the transmission device 6. The inner and outer surfaces of the mounting ring 41 are provided with mounting grooves, and two limit rings 45 are provided on the outer side of the inner cavity of the inner mounting groove.

[0038] In order to fix mechanical components, such as Figure 5 As shown, the fixing device 5 includes a double-headed telescopic rod 51, and a plurality of positioning holes 52 are arranged in an array at the upper end of the double-headed telescopic rod 51. Fixing mechanisms 53 are slidably installed on both sides of the outer surface of the double-headed telescopic rod 51, and fixing pins suitable for the positioning holes 52 are provided at the connection between the two fixing mechanisms 53 and the double-headed telescopic rod 51. The protruding ends on both sides of the double-headed telescopic rod 51 extend to the inside of the mounting groove located on the inner side of the mounting ring 41, and the protruding ends on both sides of the double-headed telescopic rod 51 are provided with limiting wheels 54, which are adapted for use with the limiting ring 45. The protruding ends on both sides of the double-headed telescopic rod 51 are provided with double-headed annular hydraulic telescopic rods 55, and the double-headed annular hydraulic telescopic rods 55 are fixedly installed in the inner cavity of the mounting cavity located on the inner side of the mounting ring 41.

[0039] Furthermore, a hydraulic pushing mechanism 56 is provided in the middle of the two fixing devices 5 , and the hydraulic pushing mechanism 56 is fixedly installed at the lower end of the mounting ring 41 .

[0040] Furthermore, the inner cavity of the hydraulic pushing mechanism 1 56 is filled with hydraulic oil, and the inner cavity of the hydraulic pushing mechanism 1 56 is communicated with the inner cavities of the two double-headed annular hydraulic telescopic rods 55 through hydraulic pipes.

[0041] Specifically, before the mechanical component needs to be repaired by surfacing welding, the hydraulic pushing mechanism 56 can be turned on first, so that the hydraulic oil in the inner cavity of the hydraulic pushing mechanism 56 enters the inner cavities of the two double-headed annular hydraulic telescopic rods 55 respectively, and the arc-shaped extension rods on both sides of the inner cavities of the two double-headed annular hydraulic telescopic rods 55 will extend, thereby causing the double-headed annular hydraulic telescopic rods 55 to push the double-headed telescopic rod 51 to move. Since the double-headed telescopic rod 51 is gradually pushed toward the center of the mounting ring 41, the double-headed telescopic rod 51 will gradually extend during the movement of the double-headed telescopic rod 51. During this process, the limiting wheels 54 at both ends of the double-headed telescopic rod 51 will move in the mounting cavity inside the mounting ring 41.

[0042] Furthermore, when the fixing devices 5 on both sides move to a position that matches the mechanical component, the staff can adjust the position between the two fixing mechanisms 53 on the outer surface of the double-headed telescopic rod 51, and then fix the mechanical component through the four fixing mechanisms 53. During this process, the fixing devices 5 on both sides can fix mechanical components of different sizes, thereby improving the adaptability of the device.

[0043] Furthermore, the fixing mechanism 53 is composed of a screw, a limit frame and two fixing blocks. When the staff rotates the screw through the tool, it will drive the two fixing blocks to move toward each other or away from each other, thereby achieving the fixing and release of the mechanical components. This is the prior art and will not be described in detail in this specification.

[0044] Embodiment 2

[0045] This embodiment further improves the transmission device 6 on the basis of the first embodiment. After the mechanical component is fixed, it may be necessary to adjust the direction of the mechanical component according to the position where the mechanical component needs to be repaired. In order to facilitate the staff to adjust the direction of the mechanical component, Figure 4 As shown, a gear ring 44 is provided on the bottom wall of the inner cavity of the mounting groove located on the outside.

[0046] Further, such as Figure 7 and Figure 8 As shown, the transmission device 6 includes a fixed plate 61, which is fixedly mounted on the outer surface of the protective cover 2. A positioning mechanism 62 is provided in the middle of the fixed plate 61, and the positioning mechanism 62 is rotatably mounted on the upper end of the support frame 1. Hydraulic push mechanisms 63 are provided on both upper and lower sides of the outer surface of the fixed plate 61. The inner cavities of the two hydraulic push mechanisms 63 are filled with hydraulic oil. The two hydraulic push mechanisms 63 are connected to two hydraulic output mechanisms 67 through hydraulic pipes. The four hydraulic output mechanisms 67 are respectively fixedly mounted on the upper and lower sides of the outer surface of the connecting plate 42 close to the hand wheel 65. The output rods of the four connecting plates 42 are all provided with limiting plates 68. A hand wheel 65 is provided at one end of the positioning mechanism 62 away from the fixed plate 61. A push ring 66 is provided on the outer surface of the hand wheel 65 close to the fixed plate 61. The inner cavity surface of the push ring 66 is slidably connected to the arc push rods in the two hydraulic push mechanisms 63. A positioning pin 64 is provided on the outer surface of the fixed plate 61 close to the hydraulic push mechanism 1 56.

[0047] Furthermore, a non-slip material is applied to the outer surface of the limiting plate 68 on a side close to the mounting ring 41 , and the limiting plate 68 is adapted for use with the limiting holes on the four limiting plates 43 located on a side close to the hand wheel 65 .

[0048] Furthermore, a fixing plate 61 and a positioning pin 64 are also provided on the side of the outer surface of the protective cover 2 away from the transmission device 6 , and the positioning pin 64 is adapted to be used with the fixing hole on the connecting plate 42 .

[0049] Specifically, after the mechanical components are fixed on the two fixing devices 5, the staff can move the position of the positioning mechanism 62 to enable the positioning mechanism 62 to transmit different mechanisms. When the staff turns the hand wheel 65, the hand wheel 65 can drive the mounting ring 41 to rotate horizontally, and can also drive the mounting ring 41 to rotate vertically, but the two will not occur at the same time, thereby adjusting the angle and position of the mechanical components fixed on the two fixing devices 5, making it convenient for the staff to perform subsequent welding repair operations on the mechanical components.

[0050] Furthermore, when the staff adjusts the position of the positioning mechanism 62 through the handwheel 65, if the staff pushes the handwheel 65 to move closer to the mounting ring 41, at this time, the handwheel 65 pushes the hydraulic oil in the inner cavity of the two hydraulic pushing mechanisms 63 to enter the inner cavity of the four hydraulic output mechanisms 67 respectively through the push ring 66, so that the four hydraulic output mechanisms 67 output, and respectively push the four limiting plates 68 to move toward the side close to the mounting ring 41. When the limiting plates 68 contact the surface of the mounting ring 41, since the surface of the limiting plates 68 is sprayed with anti-slip material, the four limiting plates 68 can limit the rotation of the mounting ring 41 in the horizontal direction. At this time, the staff can adjust the angle of the mounting ring 41 in the horizontal direction.

[0051] Furthermore, if the staff pulls the handwheel 65 to move to the side away from the mounting ring 41, the push ring 66 will pull the two hydraulic pushing mechanisms 63 to move, so that the two hydraulic pushing mechanisms 63 will re-absorb the hydraulic oil in the inner cavity of the four hydraulic output mechanisms 67 into their inner cavity. At this time, the four limiting plates 68 no longer restrict the mounting ring 41. When the staff turns the handwheel 65, the mounting ring 41 will rotate in the vertical direction, thereby allowing the staff to adjust the angle of the mechanical component in the vertical direction.

[0052] Furthermore, after the staff has completed the surfacing repair of the upper surface of the mechanical component, the transmission device 6 can be used to drive the mounting ring 41 to flip, so that the staff can perform surfacing repair on the lower surface of the mechanical component. There is no need to remove the mechanical component and then fix it on the two fixing devices 5 on the auxiliary device, thereby improving work efficiency.

[0053] Furthermore, when the staff does not need the installation ring 41 to rotate in the vertical direction, the staff can insert the positioning pin 64 into the fixing hole on the connecting plate 42. Since the fixing plate 61 cannot rotate, after the positioning pin 64 is inserted into the fixing hole on the connecting plate 42, the connecting plate 42 cannot rotate either, thereby restricting the installation ring 41 through the connecting plate 42.

[0054] In order to enable the positioning mechanism 62 to not only drive the mounting ring 41 to rotate, but also enable the mounting ring 41 to flip, as shown in FIG. Fig.10 and Fig.11 As shown, the positioning mechanism 62 includes a mounting cylinder 621, which is fixedly mounted in the middle of the fixing plate 61, and the mounting cylinder 621 is rotatably connected to the middle of the connecting plate 42. A plurality of transmission pins are arranged in an array on one side of the inner cavity of the mounting cylinder 621 away from the fixing plate 61, and a connecting handle 622 is arranged in the middle of the inner cavity of the mounting cylinder 621. Both ends of the connecting handle 622 extend to the outside of the mounting cylinder 621, and one end of the connecting handle 622 away from the fixing plate 61 is fixedly connected to the middle of the hand wheel 65, and the outer surface of the connecting handle 622 is away from the fixing plate 61. A transmission bar 625 adapted to be used with a transmission pin is arranged in an array on one side of the fixed plate 61, a cross groove is provided at one end of the connecting handle 622 close to the fixed plate 61, a driven rod 623 is arranged in the middle of the inner cavity of the cross groove, and the end of the driven rod 623 away from the transmission bar 625 extends to the inside of the mounting groove located on the outside of the mounting mechanism 4, four driven pins adapted to be used with the cross groove are arranged on the side of the outer surface of the driven rod 623 away from the transmission bar 625, and a gear 624 is arranged on the end of the driven rod 623 away from the transmission bar 625.

[0055] Furthermore, the gear 624 is meshingly connected with the gear ring 44 .

[0056] Specifically, when the staff pushes the handwheel 65 to move toward the side close to the mounting ring 41, the handwheel 65 will push the connecting handle 622 to move, so that the surface of the cross groove of the connecting handle 622 contacts the driven pin on the outer surface of the driven rod 623. At this time, the transmission bar 625 on the surface of the connecting handle 622 no longer contacts the transmission pin in the inner cavity of the mounting cylinder 621. When the staff turns the handwheel 65 at this time, the handwheel 65 can drive the gear 624 to rotate through the connecting handle 622 and the driven rod 623. Since the gear 624 is meshed and connected to the gear ring 44, when the gear 624 rotates, it will drive the mounting ring 41 to rotate in the horizontal direction.

[0057] Furthermore, when the staff pulls the handwheel 65 to move to the side away from the mounting ring 41, the cross groove on one side of the connecting handle 622 disengages from the driven pin on the surface of the driven rod 623, and at this time, the transmission bar 625 on the surface of the connecting handle 622 will contact the transmission pin on the inner cavity surface of the mounting cylinder 621. If the staff rotates the handwheel 65 at this time, the handwheel 65 drives the connecting plate 42 to rotate through the connecting handle 622 and the mounting cylinder 621, and then the connecting plate 42 drives the mounting ring 41 to rotate in the vertical direction.

[0058] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
