[0033] The present invention will be further explained below with reference to specific embodiments.

[0034] Please see Figure 1 and Figure 2This embodiment provides a steel plate stamping automotive axle housing rounding device, including a cutting table 10, a cutting component 20, a positioning component 30, a first driving component 40, and a second driving component 50. The cutting table 10 has a top plate 104 fixedly mounted on its upper part by several uprights 103. The positioning component 30 is located below the top plate 104. The second driving component 50 is installed at the bottom of the top plate 104 and is used to drive the positioning component 30 to move up and down. When the positioning component 30 moves down, it acts on the outer wall of the axle housing jaw to position the axle housing. The cutting component 20 is located inside the positioning component 30. The first driving component 40 is installed on the upper part of the positioning component 30. After the axle housing is positioned by the positioning component 30, the first driving component 40 drives the cutting component 20 to rotate to round the axle housing jaw.

[0035] When it is necessary to cut the axle housing and dental prosthesis into a circle, the axle housing can be placed on the upper part of the cutting table 10 so that the axle housing and dental prosthesis are located below the positioning component 30. Then, the second drive component 50 drives the positioning component 30 to move downward. When the positioning component 30 moves downward, it positions the axle housing. Then, the first drive component 40 drives the cutting component 20 to rotate in order to cut the positioned axle housing and dental prosthesis into a circle.

[0036] Please see Figure 1 In one embodiment, the positioning component 30 includes positioning rods 302 and mounting plate 304. The positioning rods 302 are provided in several groups, and the positioning rods 302 are disposed at the bottom of the mounting plate 304 and distributed in a ring.

[0037] After the axle housing is placed on the upper part of the cutting table 10, the second drive assembly 50 drives the mounting plate 304 and several positioning rods 302 to move downward. When the positioning rods 302 move downward, if there is a deviation in the position of the placed axle housing, the lower end of a certain group of positioning rods 302 can act on the outer wall of the axle housing tooth package in advance, thereby pushing the axle housing to move until the lower ends of several positioning rods 302 act on the outer wall of the axle housing tooth package together, thus completing the positioning of the axle housing tooth package. At this time, the first drive assembly 40 drives the cutting assembly 20 to rotate in order to perform rounding processing on the axle housing tooth package.

[0038] Please see Figure 1 as well as Figure 3In one embodiment, the upper ends of a plurality of positioning rods 302 penetrate the mounting plate 304 and are movably engaged with the mounting plate 304. The plurality of positioning rods 302 are also connected to the mounting plate 304 via an elastic element 305, which provides elastic support for the plurality of positioning rods 302. The first drive assembly 40 includes a first rack 401, a first gear 402, a threaded sleeve 403, a screw 405, a second rack 406, and a second gear 407. The second gear 407 is disposed on the upper part of the mounting plate 304. One end of the cutting assembly 20 is connected to the second gear 407. One end extends to the lower part of the mounting plate 304. The first rack rod 401 is fixedly mounted on the side wall of one of the positioning rods 302. The threaded sleeve 403 is rotatably mounted on the upper part of the mounting plate 304 through the support 404. The first gear 402 is fixedly mounted on one end of the threaded sleeve 403 and meshes with the first rack rod 401. The screw 405 is screwed to the other end of the threaded sleeve 403. One end of the second rack rod 406 is fixedly connected to the end of the screw 405 located outside the threaded sleeve 403, and the other end extends to one side of the second gear 407 and meshes with the second gear 407.

[0039] When the second drive assembly 50 moves the mounting plate 304 and several positioning rods 302 downwards, the mounting plate 304 can also move the first gear 402, threaded sleeve 403, screw 405, second rack 406, second gear 407, and cutting assembly 20 downwards synchronously. When the lower ends of all the positioning rods 302 act on the outer wall of the axle housing jaw assembly to complete the positioning of the axle housing jaw assembly, as the mounting plate 304 continues to move downwards, several positioning rods 302 stop moving downwards and move upwards relative to the mounting plate 304. At this time, the elastic element 305 is compressed, and a certain group of positioning rods 302... 02 Compared to the mounting plate 304 moving upward, which drives the first rack rod 401 on its side wall to move upward, the first rack rod 401 and the first gear 402 meshing together, thereby driving the threaded sleeve 403 to rotate. When the threaded sleeve 403 rotates, it drives the screw 405 to move outward through the threaded engagement with the screw 405. When the screw 405 moves, it drives the second rack rod 406 to move. The second rack rod 406 and the second gear 407 meshing together, thereby driving the cutting assembly 20 to rotate, thereby performing rounding processing on the bridge housing tooth package.

[0040] Please see Figure 1 , Figure 3 as well as Figure 4In one embodiment, a connecting rod 303 is fixedly disposed inside the positioning rod 302, and a central ring 306 is fixedly disposed at the end of the connecting rod 303 away from the positioning rod 302. The cutting assembly 20 includes a laser cutting head 201, a support plate 202, a rotating cylinder 203, and a rotating shaft 204. The rotating cylinder 203 vertically passes through the central ring 306 and is rotatably connected to the central ring 306. One end of the support plate 202 is fixedly connected to the bottom of the rotating cylinder 203, and the other end is fixedly connected to the laser cutting head 201. One end of the rotating shaft 204 is fixedly connected to the second gear 407, and the other end passes through the mounting plate 304 and extends into the interior of the rotating cylinder 203. The rotating shaft 204 is rotatably connected to the mounting plate 304, and the rotating shaft 204 and the rotating cylinder 203 are in telescopic cooperation. A key 2041 is provided on the side wall of the rotating shaft 204, and a keyway that cooperates with the key 2041 is provided on the inner wall of the rotating cylinder 203. One end of the elastic element 305 is connected to the bottom wall of the mounting plate 304, and the other end is connected to the central ring 306.

[0041] After the lower ends of several positioning rods 302 work together on the outer wall of the axle housing jaw assembly to complete the positioning of the axle housing jaw assembly, the laser cutting head 201 moves to a position above the axle housing jaw assembly. As the mounting plate 304 continues to move downward, the positioning rods 302 stop moving downward and move upward relative to the mounting plate 304. The first rack rod 401 meshes with the first gear 402, thereby driving the threaded sleeve 403 to rotate. Through the threaded engagement between the threaded sleeve 403 and the screw 405, the second rack rod 406 moves. When the second rack rod 406 moves, it meshes with the second gear 407, thereby driving the rotating shaft 204 to rotate. When shaft 204 rotates, the key 2041 and keyway work together to drive the rotating drum 203 to rotate. The rotating drum 203 drives the laser cutting head 201 to rotate via the support plate 202, thereby performing circular cutting on the axle housing jaw assembly. When the aforementioned positioning rods 302 stop moving downwards, the connecting rod 303, the central ring 306, the rotating drum 203, the support plate 202, and the laser cutting head 201 simultaneously stop moving downwards, ensuring that the laser cutting head 201 always rotates at a predetermined height above the axle housing jaw assembly, thus achieving smooth circular cutting of the axle housing jaw assembly and improving the circular cutting effect. The laser cutting head 201 rotates at the predetermined height position... During the process, the mounting plate 304 drives the rotating shaft 204 to continue moving downwards, and the rotating shaft 204 moves into the rotating cylinder 203. After the axle housing tooth circle is cut, the second drive assembly 50 drives the mounting plate 304 to move upwards. When the mounting plate 304 moves upwards, the elastic element 305 pushes the central ring 306, causing the central ring 306, rotating cylinder 203, support plate 202, laser cutting head 201, connecting rod 303, and several positioning rods 302 to move downwards relative to the mounting plate 304. When a certain group of positioning rods 302 moves downwards relative to the mounting plate 304, the first rack rod 401 on its side wall meshes with the first gear 402 in the opposite direction, thereby driving... The threaded sleeve 403 rotates in the reverse direction, which drives the screw 405 and the second rack 406 to move in the reverse direction. When the second rack 406 moves in the reverse direction, it drives the second gear 407 to rotate in the reverse direction, which in turn drives the rotating shaft 204, the rotating drum 203, the support plate 202 and the laser cutting head 201 to rotate in the reverse direction. When the positioning rods 302 move down a predetermined distance relative to the mounting plate 304, the mounting plate 304 drives the positioning rods 302 and the laser cutting head 201 to move up synchronously. The lower ends of the positioning rods 302 separate from the outer wall of the axle housing jaw package. Then the axle housing jaw package can be removed from the upper part of the cutting table 10.

[0042] Please see Figure 3In one embodiment, a guide rail 3041 is fixedly provided on the upper part of the mounting plate 304, and a slider 408 is fixedly provided on the bottom of the second rack rod 406. The slider 408 slides with the guide rail 3041 so that when the threaded sleeve 403 rotates, it can smoothly drive the screw 405 to move outward, thereby smoothly driving the second rack rod 406 to move, so that the second rack rod 406 and the second gear 407 can smoothly mesh, thereby driving the laser cutting head 201 to rotate smoothly to cut a circle.

[0043] Please see Figure 1 In one embodiment, a roller 301 is rotatably provided at the lower end of each of the positioning rods 302.

[0044] When the lower end of a certain set of positioning rods 302 is applied to the outer wall of the axle housing tooth pack, the corresponding roller 301 can roll along the outer wall of the axle housing tooth pack, thereby reducing the frictional force applied by the lower end of the positioning rod 302 to the outer wall of the axle housing tooth pack, avoiding scratches on the outer wall of the axle housing tooth pack, and improving the positioning effect.

[0045] In one embodiment, the elastic element 305 may be a spring or a metal sheet, and there is no limitation on this.

[0046] Please see Figure 1 as well as Figure 5 In one embodiment, a holding seat 102 is provided on the upper part of the cutting table 10, and a plurality of balls 1021 are movably embedded in the bottom of the holding seat 102, and the plurality of balls 1021 act on the upper surface of the cutting table 10.

[0047] After the axle housing is placed on the upper part of the cutting table, the holding seat 102 provides support for the axle housing. When the lower end of a set of positioning rods 302 acts on the outer wall of the axle housing jaw pack and drives the axle housing to move, the axle housing can drive the holding seat 102 so that a number of balls 1021 at the bottom of the holding seat 102 roll adaptively along the upper part of the cutting table 10, thereby improving the flexibility of the axle housing when moving and improving the positioning effect of the axle housing jaw pack.

[0048] Please see Figure 1 as well as Figure 2 In one embodiment, the upper part of the cutting table 10 is provided with a material drop port 101. After the laser cutting head 201 rotates and completes the circular cutting of the bridge housing tooth package, the cut circular piece can pass through the material drop port 101.

[0049] In one embodiment, the second drive component 50 may be a hydraulic cylinder or a linear motor, and there is no limitation on this.

[0050] In this embodiment of the invention, when it is necessary to perform circular cutting on the axle housing jaw assembly, the axle housing can be placed on the upper part of the cutting table 10, so that the axle housing jaw assembly is located below the positioning component 30. Then, the second driving component 50 drives the positioning component 30 to move downward. When the positioning component 30 moves downward, it positions the axle housing. Then, the first driving component 40 drives the cutting component 20 to rotate, so as to perform circular cutting on the positioned axle housing jaw assembly. Compared with the prior art, when circular cutting is performed on the automotive axle housing, there is no need to use a clamping mechanism to clamp the axle housing to complete the automatic positioning of the axle housing jaw assembly, which has the advantages of good circular cutting effect and high circular cutting efficiency.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
