[0015] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0016] A cross-axis processing device includes a workbench 1, and a clamping jaw assembly 2 for clamping the cross-axis is movably fixed on one side of the workbench 1, wherein the clamping jaw assembly 2 can be a disc-type clamping for clamping one end of the cross-axis, and the aforementioned clamping jaw assembly 2 is driven to rotate by a motor assembly, thereby driving the clamped cross-axis to rotate. A positioning unit is arranged on the workbench 1 facing the aforementioned clamping jaw assembly 2, and a push rod 3 is fixed on the positioning unit. The center of the push rod 3 and the clamping jaw assembly 2 is located on the same axis, and a tool assembly 4 for cross-axis processing is movably fixed on the positioning unit.

[0017] Because the center of the end of the cross shaft is a concave structure, the push rod 3 can be pushed into the end of the cross shaft facing away from the clamping jaw assembly 2 to play a supporting role, avoiding the fixation method of clamping the two ends of the cross shaft with the clamping jaws at this end. The center of the push rod 3 and the clamping jaw assembly 2 are located on the same axis to ensure that the cross shaft will not deviate during rotation, thereby affecting the processing of the tool assembly 4. This fixing method can greatly reduce the difficulty of fixing the cross shaft during processing, so that the fixation of the cross shaft can be completed more quickly, thereby carrying out the processing process, which can effectively improve production efficiency.

[0018] The aforementioned positioning unit includes an inclined processing table 5, which is fixedly arranged on a position adjustment component 6, a fixed table 7 is arranged on the processing table 5, an adjustment component is movably fixed on the fixed table 7, and the push rod 3 is fixedly arranged on the adjustment component for adjusting the vertical position of the push rod 3.

[0019] The aforementioned adjustment assembly includes a fixed rod 9 and a movable rod 10 embedded in the fixed rod 9. The top rod 3 is vertically fixed on the movable rod 10. An adjustment block 11 is fixedly arranged on the fixed rod 9. A plurality of tooth grooves are arranged on the side of the movable rod 10 facing the adjustment block 11. The adjustment block 11 can be embedded in the tooth grooves to tighten the movable rod 10, thereby completing the fixation of the movable rod 10, thereby completing the vertical position adjustment and fixation of the top rod 3.

[0020] A displacement mechanism is fixedly arranged on the surface of the aforementioned processing table 5. The aforementioned displacement mechanism includes a slide groove 8 arranged on the surface of the processing table 5. The slide groove 8 is fixedly arranged along the rotation direction of the processing table 5. A slider is arranged in the slide groove 8. A tool assembly 4 is fixedly arranged on the slider. The slider is sleeved on a screw and threadedly matched with the screw and the screw is kept parallel to the slide groove 8. The aforementioned screw is coaxially fixed with the motor. Under the drive of the motor, the slider matched with the screw thread can reciprocate along the length direction of the slide groove 8, so as to adjust the position of the tool assembly 4 thereon, and to approach or move away from the fixed cross axis. When the tool assembly 4 approaches the cross axis, the processing process of the cross axis can be completed based on the tool head fixed thereon.

[0021] The aforementioned tool assembly 4 includes a tool disc, on which a number of clamps for fixing the tool heads are evenly arranged. Different tool heads are fixed on the tool disc by means of the aforementioned clamps to meet the processing requirements of cross shafts of different sizes. The tool disc is coaxially fixed with the rotating shaft of the motor. After being driven by the motor to rotate at a certain angle, the tool head can be switched.

[0022] The position adjustment assembly 6 is described in detail below. The position adjustment assembly 6 includes a servo motor and a screw rod. The servo motor and the screw rod are coaxially fixed. A movable block is fixedly arranged under the processing table 5.

After being driven by the servo motor, the processing table 5 can be driven to approach or move away from the clamping jaw assembly 2, so as to facilitate the replacement of the cross shaft fixed by the clamping jaw assembly 2.

[0023] In actual application, the cross shaft is first fixed on the clamping jaw assembly 2, and the height of the push rod 3 is adjusted accordingly so that the center of the push rod 3 and the clamping jaw assembly 2 are located on the same axis. Then, the tool assembly 4 is driven to replace the corresponding tool head to adapt to the current cross shaft processing process. After the adjustment is completed, the position adjustment assembly 6 drives the processing table 5 to approach the cross shaft to complete the limit, and the position of the tool assembly 4 is adjusted by the displacement mechanism. Then, the motor assembly drives the cross shaft itself to rotate to complete the processing process.
