Description

Technical Field

[0001] The utility model belongs to the technical field of gear rolling machine equipment, and in particular relates to an adjusting mechanism of a horizontal gear rolling forming machine. Background Art

[0002] The gear rolling machine is a device that uses a gear rolling die to process shaft workpieces. It can form the required tooth shape or spline on the workpiece surface through extrusion and friction. The gear rolling machine includes a top and a support block. The top is located at the center of both ends of the support block. When processing the workpiece, the metal shaft workpiece needs to be placed on the support block first, and the support block is used to support the workpiece. Then the support block is used to realize the self-centering of the workpiece, and then the top is used to clamp the center of both ends of the workpiece, and it is moved to the middle of the gear rolling die to perform gear rolling forming.

[0003] A Chinese patent with publication number CN218946238U discloses a gear rolling machine for processing universal joint optical axes, including a support frame, a support rod, a threaded rod and a rotating block, wherein the support frame is slidably arranged on the support rod, the end of the support rod is rotatably connected to the threaded rod, and the rotating block is connected to the threaded rod. When in use, the x-axis position of the support frame on the support rod is first fixed according to the specifications of the workpiece, and then the threaded rod is rotated by the rotating block so that the threaded rod fixes the y-axis position of the support rod, thereby realizing the adjustment of the three-dimensional spatial position of the support frame, and then adapting to shaft workpieces of different specifications to ensure that they are aligned with the center of the top.

[0004] In the technical solution of the above patent, in order to align the center of the shaft workpiece with the top when loading, it is necessary to achieve a self-centering effect when the shaft workpiece is placed on the support frame. However, when adjusting the support frame, the x-axis and y-axis directions of the support frame need to be adjusted separately to achieve the three-dimensional spatial position adjustment of the support frame. The adjustment process is relatively cumbersome and has poor practicality. Utility Model Content

[0028] Please refer again Figure 1As shown, an adjustment seat 2 is slidably provided on the guide rod 1; a fixed block 14 is fixedly connected to the bottom center of the adjustment seat 2, and fixing nuts 15 are threadedly fixedly connected to the threaded rod 16 at positions corresponding to both sides of the fixing block 14, and the adjustment seat 2 is fixedly connected to the threaded rod 16 through the cooperation of the fixing nuts 15 and the fixing block 14; a slider 13 is fixedly connected to the bottom position of the adjustment seat 2 corresponding to the guide rod 1, and the adjustment seat 2 is slidably connected to the guide rod 1 through the slider 13, and the adjustment seat 2 is supported and fixed on the input side of the gear rolling machine by the guide rod 1 and the threaded rod 16.

[0029] Please refer again Figure 1-Figure 4 As shown, a groove body 5 is provided in the adjustment seat 2; a symmetrically arranged support frame 3 is slidably provided in the groove body 5, and the support frame 3 is used to support shaft workpieces; the support frames 3 are arranged in a cross-type manner in the groove body 5; a cross groove 4 is provided on one of the support frames 3, and the other support frame 3 fits with the cross groove 4; an adjustment block 6 is fixedly connected to the end of the bottom of the support frame 3 away from each other; a first support block 9 and a second support block 10 are respectively fixedly connected to the end of the support frame 3 close to each other, wherein the second support block 10 is connected to the support frame 3 with the cross groove 4; the adjustment seat 2 is respectively provided with a first slide groove 11 and a second slide groove 12 that fit in the positions corresponding to the first support block 9 and the second support block 10, the first support block 9 is slidably connected in the first slide groove 11, and the second support block 10 is slidably connected in the second slide groove 12, so as to maintain the stability of the support frame 3 inside the slide groove.

[0030] Please refer again Figure 3 As shown, the adjustment seat 2 is rotatably connected with a bidirectional screw rod 7 along the length direction. The bidirectional screw rod 7 passes through the first support block 9, and the two ends of the bidirectional screw rod 7 are rotatably connected with the adjustment block 6 respectively; the bidirectional screw rod 7 is fixed with a knob 8 at a position corresponding to the outside of the adjustment seat 2, which is used to assist the operator to rotate the bidirectional screw rod 7.

[0031] Please refer again Figure 3 As shown, the upper surface of the adjustment seat 2 is provided with scales 18 at positions corresponding to the support frame 3 . The scales 18 are symmetrically arranged at both ends of the adjustment seat 2 to assist the operator in fixing the position of the support frame 3 .

[0032] During the specific operation, firstly, the guide rod 1 and the threaded rod 16 are fixed to the input side of the gear rolling machine through the flange 17, and then the adjustment seat 2 is inserted into the fixed position on the guide rod 1, and the position of the adjustment seat 2 is locked by the cooperation of the threaded rod 16, the fixing nut 15 and the fixing block 14, so as to fix the adjustment seat 2;

[0033] When processing shaft workpieces of different specifications, the corresponding bidirectional screw rod 7 is driven to rotate by turning the knob 8. During the rotation of the bidirectional screw rod 7, since the support frame 3 slides in the slide groove and the adjustment block 6 is threadedly connected to the bidirectional screw rod 7, the two adjustment blocks 6 are forced to move toward each other under the cooperation of the bidirectional screw rod 7 and the slide groove, so that they are close to or away from each other, thereby making the support frames 3 close to or away from each other. When the support frames 3 are close to each other, the center of the X-shaped structure formed between the support frames 3 moves upward, which is suitable for self-centering of shaft workpieces with smaller diameters; when the support frames 3 are away from each other, the center of the X-shaped structure formed between the support frames 3 moves downward, which is suitable for self-centering of shaft workpieces with larger diameters. Larger shaft workpieces are self-centering, and then through the marking of scale 18, the operator can accurately adjust the support frame 3 to the specified position, which is convenient for the center to accurately clamp the two ends of the shaft workpiece and send the workpiece into the gear rolling machine for processing. The support seat of the support frame 3 fixes the y-axis position of the adjustment seat 2, adjusts the x-axis position of the adjustment seat 2, and cooperates with the X-shaped cross arrangement of the support frame 3 to achieve the position adjustment of the center, thereby ensuring that shaft workpieces of different specifications can achieve the purpose of self-centering after being placed on the support frame 3, ensuring that the center axis of the shaft workpiece is always aligned with the center of the top, thereby improving the adjustment speed of the support frame 3 and improving practicality.
