[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1, such as Figures 1-4The present invention provides the following technical solution to address the problem of inconvenience in centering the steering knuckle during machining: A pushing mechanism is disclosed, comprising a base plate 1, with drilling assemblies 2 symmetrically mounted on the upper surface of the base plate 1, and a steering workpiece 3 connected to the upper surface of the base plate 1 near the drilling assemblies 2; a connecting block 101 is connected in the middle of the upper surface of the base plate 1, with rotating grooves 102 on both sides of the connecting block 101, and multiple sets of connecting blocks 101; a fixing block 108 is fixed to the top of the connecting block 101, and a guide for the steering knuckle is provided inside the connecting block 101. The pushing mechanism includes a rotating block 103 that rotates inside a rotating groove 102. A guide groove 104 is provided on the top of the connecting block 101. A guide block 105 slides through the guide groove 104. A pressing block 106 is fixed on the top of the guide block 105. A threaded rod 107 is rotatably connected through the guide block 105 and the guide groove 104. The threaded rod 107 and the guide block 105 are also threaded together. A motor is connected to the end of the threaded rod 107 away from the fixed block 108. The motor is installed at the end of the connecting block 101.
[0030] When the steering knuckle needs machining, first place the steering workpiece 3 on the upper surface of the connecting block 101, then start the motor. The motor output can drive the threaded rod 107 to rotate. When the threaded rod 107 rotates, it can drive the guide block 105 to slide threadedly. When the guide block 105 slides threadedly, it can slide through the guide groove 104. When the guide block 105 slides, it can drive the pressing block 106 to slide. When the pressing block 106 slides to the side of the placed steering workpiece 3, it can press. When the steering workpiece 3 is pressed, it can slide on the surface of the connecting block 101. When the steering workpiece 3 slides, its inner side can press the rotating block 103. When 103 is squeezed, it can rotate inside the rotating groove 102 through friction with the steering workpiece 3. The rotation of the rotating block 103 can prevent the steering workpiece 3 from being stuck by the friction of the connecting block 101 when it tilts and moves. Since the two ends of the connecting block 101 are different sizes, the tilt angle of the steering workpiece 3 will slowly return to the correct position during the movement. After the steering workpiece 3 returns to the correct position, it will move by friction on both sides of the rotating block 103. When the steering workpiece 3 is pushed to the side of the fixed block 108 by the squeezing block 106, it can be squeezed and positioned. After the steering workpiece 3 is positioned, it can be drilled through the drilling assembly 2, which improves the efficiency and convenience of steering knuckle processing.
[0031] Example 2, as follows Figures 3-6The present invention provides the following technical solution to address the problem of low stability during steering knuckle processing: Based on Embodiment 1, a pressing mechanism is disclosed: A telescopic groove 109 is symmetrically provided on the side of the fixed block 108. An pressing mechanism to improve steering knuckle stability is provided inside the fixed block 108. The pressing mechanism includes a sliding groove 110, which is opened through the side of the telescopic groove 109. An L-shaped block 111 is slidably connected inside the sliding groove 110. An anti-slip pad is connected to the bottom of the L-shaped block 111. A pressing groove 112 is provided on the side of the L-shaped block 111. A telescopic rod 113 is slidably connected through the pressing groove 112 and the inside of the telescopic groove 109. A spring is connected between the telescopic rod 113 and the telescopic groove 109. A T-shaped groove 114 is provided on the side of the L-shaped block 111 away from the pressing groove 112. A T-shaped block 115 is slidably connected through the T-shaped groove 114 and fixed inside the sliding groove 110.
[0032] During steering knuckle processing, the extrusion block 106 can extrude the steering workpiece 3 through the fixing block 108. Before the steering workpiece 3 is extruded to the side of the fixing block 108, it first extrudes the end of the telescopic rod 113. When the telescopic rod 113 is extruded, it can slide through the telescopic groove 109 and the extrusion groove 112. When the telescopic rod 113 slides, it can extrude the spring through the telescopic groove 109. When the telescopic rod 113 slides inside the extrusion groove 112, it can extrude the inclined surface of the extrusion groove 112. When the extrusion groove 112 is extruded, the L-shaped block 111 can slide through the sliding groove 110. At the same time, the L-shaped block 111 can drive the T-shaped groove 114 to move downward. When the T-shaped groove 114 moves, it can slide through the T-shaped block 115. When the L-shaped block 111 slides, it can drive the rubber pad to move to the upper surface of the steering workpiece 3 for extrusion. At this time, the steering workpiece 3 can be extruded by the extrusion block 106, the fixing block 108 and the L-shaped block 111 at the same time, which further improves the stability of the steering workpiece 3 and indirectly improves the processing effect of the steering workpiece 3.
[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
