Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example

[0032] like Figure 1-6 As shown, the slewing bearing integral quenching machine arm of the present invention includes a base 1 and a mounting plate 4 located above the base 1. The bottom end of the mounting plate 4 is provided with a horizontally rotatable adjustment plate 6. Several movable driven arms 7 are uniformly arranged along the side wall of the adjustment plate 6 in the circumferential direction. Each driven arm 7 has a rotatable extension arm 9 on the bottom surface of the end away from the adjustment plate 6. A lifting frame 10 is fixedly provided on the lower side surface of each extension arm 9. The several lifting frames 10 can lift the workpiece to be processed when facing each other or facing away from each other. In this embodiment, four driven arms 7 are used, and the four driven arms 7 are arranged perpendicular to each other, which makes it easier to clamp or lift the workpiece to be processed.

[0033] Specifically, a second adjusting motor 8 is provided on the upper surface of the driven arm 7 away from the adjusting plate 6. The output shaft of the second adjusting motor 8 passes through the driven arm 7 and is connected to the extension arm 9 to drive the extension arm 9. In this embodiment, the second adjusting motor 8 serves as a driving mechanism and as a power source to adjust the angle of the extension arm 9.

[0034] Specifically, the upper surface of the mounting plate 4 is provided with a first adjusting motor 5. The output shaft of the first adjusting motor 5 passes through the mounting plate 4 and is connected to the adjusting plate 6 to drive the adjusting plate 6. In this embodiment, the first adjusting motor 5 can run when the device clamps an irregular workpiece to be processed, thereby adjusting the angle of the workpiece to be processed, so as to facilitate the processing of the workpiece.

[0035] Specifically, the interior of the adjusting plate 6 is provided with a number of second telescopic rods 19 evenly arranged in the horizontal direction and circumferential direction. The output shaft of each second telescopic rod 19 is connected to the driven arm 7 and pushes it to move. In this embodiment, the second telescopic rod 19 can adjust the position of the driven arm 7, thereby facilitating the clamping of the workpiece to be processed.

[0036] Specifically, a rotatable first drive roller 12 is horizontally provided in the lifting frame 10. One side of the first drive roller 12 penetrates the upper surface of the lifting frame 10 and contacts the bottom surface of the workpiece to be processed. In this embodiment, the first drive roller 12 facilitates the adjustment of the position of the workpiece to be processed during rotation.

[0037] Specifically, a third adjusting motor 11 is fixedly provided on the side surface of the extension arm 9 that is different from the lifting frame 10. The output shaft of the third adjusting motor 11 passes through the extension arm 9 and is connected to the first driving roller 12 to drive it.

[0038] Specifically, a rotatable second drive roller 20 is vertically arranged inside the extension arm 9. One side of the second drive roller 20 penetrates the side wall of the extension arm 9 and contacts the side of the workpiece to be processed. A bevel gear 21 meshes with the bottom end of the second drive roller 20 and the output shaft of the third adjusting motor 11. The second drive roller 20 is set at the same height as the workpiece to be processed. In this embodiment, the second drive roller 20 can drive the workpiece to be processed during rotation.

[0039] Specifically, a first adjusting telescopic rod 2 is provided at one end of the base 1, and a rotatable adjusting arm 3 is provided at the top of the first adjusting telescopic rod 2. The free end of the adjusting arm 3 is connected to the mounting plate 4. In this embodiment, both the first adjusting telescopic rod 2 and the adjusting arm 3 can adjust the position and direction of the adjusting plate 6.

[0040] Specifically, a liquid collection tank 18 is provided on the upper surface of the base 1, a rotatable bidirectional lead screw 16 is horizontally arranged in the middle of the base 1, and a fourth adjusting motor 13 for driving the bidirectional lead screw 16 to rotate is fixed on the outer wall of the base 1. During the rotation of the fourth adjusting motor 13, the rotation of the bidirectional lead screw 16 can be effectively adjusted, thereby adjusting the distance between the two adjusting frames 14.

[0041] Adjustment brackets 14 are fitted on the two external thread sections of the bidirectional lead screw 16 with opposite rotation directions. Each adjustment bracket 14 has a rotatable adjustment column 15 at its top. A heating electromagnetic coil is installed on the side of one adjustment column 15 facing the workpiece to be processed, and a spray nozzle is installed on the side of the other adjustment column 15 facing the workpiece to be processed. In this embodiment, the heating electromagnetic coil can heat up the workpiece to be processed during the energization process, and then the quenching liquid is sprayed through the spray nozzle to cool and quench it.

[0042] Specifically, a stabilizing rod 17 is provided in the base 1 in the same direction as the bidirectional lead screw 16. The stabilizing rod 17 passes through the two adjustment frames 14. In this embodiment, the stabilizing rod 17 further improves the stability of the two adjustment frames 14 during the displacement process.

[0043] The working principle and usage process of this invention: When the operator needs to process a small workpiece during the use of this processing device, the second adjusting motor 8 drives the extension arm 9 to rotate. When the extension arm 9 rotates, it drives the lifting frame 10 to deflect, so that multiple lifting frames 10 are oriented toward the axis of the adjusting plate 6. The operator places the small workpiece to be processed inside the extension arm 9. Then the second telescopic rod 19 retracts and adjusts the distance between multiple driven arms 7, thereby bringing the lifting frames 10 closer together and lifting the workpiece to be processed.

[0044] During the operation of the third adjusting motor 11, the first driving roller 12 is driven to rotate. During the operation of the third adjusting motor 11, the second driving roller 20 is driven to rotate through the bevel gear 21. During the rotation of the second driving roller 20 and the first driving roller 12, the workpiece to be processed is rotated.

[0045] When the inner ring of the workpiece to be processed needs to be processed, the fourth adjusting motor 13 drives the bidirectional lead screw 16 during the power-on process. During the rotation of the bidirectional lead screw 16, the spacing of the adjusting frame 14 is adjusted so that the two adjusting columns 15 are located inside the workpiece to be processed. The adjusting column 15 at the top of the adjusting frame 14 can adjust the angle of the heating electromagnetic coil or the spray nozzle during the rotation process, which facilitates the heating and processing of the inner ring of the workpiece to be processed, as well as the spray cooling.

[0046] When the outer ring of the workpiece needs to be processed, the fourth adjusting motor 13 drives the bidirectional lead screw 16 during the power-on process. During the rotation of the bidirectional lead screw 16, the spacing of the adjusting frame 14 is adjusted so that the two adjusting columns 15 are located on the outside of the workpiece to be processed. Then, the workpiece to be processed is processed by heating the electromagnetic coil or spray nozzle.

[0047] When processing larger workpieces, the second adjusting motor 8 drives the extension arm 9 to rotate, which in turn drives the lifting frame 10 to rotate, so that each lifting frame 10 faces a direction away from each other. The worker places the larger workpiece on the outside of the extension arm 9, and then adjusts the distance between the multiple driven arms 7, so that the lifting frames 10 move away from each other and lift the workpiece.

[0048] During the use of this processing device, the first adjusting telescopic rod 2 adjusts the height of the adjusting arm 3, and the angle or position of the mounting plate 4 is adjusted during the rotation of the adjusting arm 3.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to further limit the present invention. All equivalent changes made based on the description and drawings of the present invention are within the protection scope of the present invention.
