Description

Technical Field

[0001] This utility model relates to the field of press fitting machine technology, specifically a press fitting machine with anti-misalignment function. Background Technology

[0002] Press fitting machines, as key equipment in the assembly of automotive parts, are widely used in the manufacturing of core components such as steering knuckles, engines, and chassis. Taking steering knuckle assembly as an example, bushings need to be precisely pressed into the assembly holes. The assembly accuracy directly affects the steering performance, driving stability, and safety of the vehicle. Therefore, high-precision press fitting machines are fundamental to ensuring vehicle quality.

[0003] Currently, in order to meet diverse market demands, automobile manufacturers need to adapt steering knuckles for multiple vehicle models on the same production line. Traditional fixtures clamp and fix the steering knuckle on both sides, but lack positioning on both sides. This can easily lead to misalignment between the steering knuckle assembly holes and bushings during the assembly process. Utility Model Content

[0004] The purpose of this invention is to provide a press-fitting machine with anti-misalignment function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a press-fitting machine with anti-misalignment function, comprising a base and a hydraulic press, wherein a turntable is rotatably connected to the surface of the base, two sets of symmetrically arranged clamps are provided on the surface of the turntable, a sliding groove is formed on the surface of the turntable, an adjustment component is provided inside the sliding groove, the adjustment component includes a bidirectional threaded rod, the end of the bidirectional threaded rod is rotatably connected to the inner wall of the sliding groove, two sets of symmetrically arranged support plates are threadedly connected to the outer wall of the bidirectional threaded rod, the support plates are slidably connected inside the sliding groove, the support plates are L-shaped, a limit block is fixedly connected to the end of the support plate, and a gear is fixedly connected to the outer wall of the bidirectional threaded rod.

[0006] Preferably, a positioning component is provided on the side wall of the turntable. The positioning component includes a protrusion, which is fixedly connected to the side wall of the turntable. A through hole is opened on the surface of the protrusion, and a lead screw is threaded into the through hole. One end of the lead screw is fixedly connected to a rotating wheel, and the other end of the lead screw is fixedly connected to a pressure plate.

[0007] Preferably, two sets of symmetrically arranged brackets are fixedly connected to the surface of the turntable at the middle of the slide groove, and a second gear is rotatably connected between the two sets of brackets, with the second gear meshing with the first gear.

[0008] Preferably, a guide rod is fixedly connected to the surface of the pressure plate, and the guide rod passes through and is slidably connected to the surface of the protrusion.

[0009] Preferably, an anti-slip pad is fixedly connected to the bottom surface of the pressure plate.

[0010] Preferably, a motor is fixedly connected to the bottom surface of the base, the output shaft of the motor passes through and is rotatably connected to the surface of the base, and the output shaft of the motor is fixedly connected to the bottom surface of the turntable.

[0011] Preferably, the bottom surface of the base is fixedly connected to four sets of symmetrically arranged support legs.

[0012] Compared with the prior art, this utility model provides a press-fitting machine with anti-misalignment function, which has the following beneficial effects:

[0013] 1. This press-fitting machine with anti-misalignment function rotates the upper gear two to make the lower gear one rotate, thereby facilitating the rotation of the bidirectional threaded rod in the slide groove, which in turn drives the two sets of L-shaped support plates to move towards each other or away from each other, so that the distance between the two sets of limit blocks can be adjusted to adapt to the limit of the side wall of the automotive steering knuckle of different sizes. In conjunction with the fixture, it avoids misalignment between the steering knuckle assembly hole and the bushing during press-fitting.

[0014] 2. This press machine with anti-misalignment function rotates the wheel, causing the screw to rotate and the pressure plate to move vertically downward. The anti-slip pad contacts the surface of the base, thereby reinforcing the position of the turntable, locking the turntable position, and preventing the turntable from shifting due to vibration during press-fitting.

[0019] like Figures 1-3As shown, this utility model provides a technical solution: a press-fitting machine with anti-misalignment function, including a base 1 and a hydraulic press. Four sets of symmetrically arranged support legs 11 are fixedly connected to the bottom surface of the base 1. The base 1 serves as the foundation of the entire machine, and the four sets of support legs 11 on the bottom surface ensure stable placement of the equipment. A turntable 2 is rotatably connected to the surface of the base 1, and a motor 3 is fixedly connected to the bottom surface of the base 1. The output shaft of the motor 3 passes through and is rotatably connected to the surface of the base 1. The output shaft of the motor 3 is fixedly connected to the bottom surface of the turntable 2. Two sets of symmetrically arranged clamps 4 are arranged on the surface of the turntable 2. The two sets of symmetrical clamps 4 are used to fix the workpiece to be press-fitted. The motor 3 drives the turntable 2 to rotate through its output shaft, realizing workpiece position switching.

[0020] like Figures 1-3 As shown, the surface of the turntable 2 is provided with a groove 5, and an adjustment component 6 is provided inside the groove 5. The adjustment component 6 includes a bidirectional threaded rod 61, the end of which is rotatably connected to the inner wall of the groove 5. Two sets of symmetrically arranged support plates 62 are threadedly connected to the outer wall of the bidirectional threaded rod 61. The support plates 62 are slidably connected inside the groove 5. The support plates 62 are L-shaped, and the ends of the support plates 62 are fixedly connected to limit blocks 63. By rotating the bidirectional threaded rod 61 in the forward or reverse direction, the two sets of L-shaped support plates 62 are driven to move towards each other or away from each other, so that the distance between the two sets of limit blocks 63 can be adjusted to accommodate different sizes of automotive steering knuckles, so that the mounting hole of the automotive steering knuckle is rotated to the bottom of the press machine to avoid misalignment. A gear 64 is fixedly connected to the outer wall of the bidirectional threaded rod 61. Two sets of symmetrically arranged brackets 65 are fixedly connected to the surface of the turntable 2 at the middle of the slide groove 5. A gear 66 is rotatably connected between the two sets of brackets 65, and the gear 66 meshes with the gear 64. The two sets of brackets 65 are used to support and position the gear 66, so that the gear 66 is above the gear 64. Thus, by rotating the upper gear 66, the lower gear 64 is rotated, which facilitates the control of the rotation of the bidirectional threaded rod 61 in the slide groove 5.

[0021] like Figures 1-3As shown, a positioning component 7 is provided on the side wall of the turntable 2. The positioning component 7 includes a protrusion 71, which is fixedly connected to the side wall of the turntable 2. A through hole is opened on the surface of the protrusion 71, and a lead screw 72 is threaded into the through hole. One end of the lead screw 72 is fixedly connected to a rotating wheel 73, and the other end of the lead screw 72 is fixedly connected to a pressure plate 74. A guide rod 75 is fixedly connected to the surface of the pressure plate 74, which passes through and slides on the surface of the protrusion 71. An anti-slip pad 76 is fixedly connected to the bottom surface of the pressure plate 74. By rotating the rotating wheel 73, the lead screw 72 rotates, which drives the pressure plate 74 to move vertically. The guide rod 75 guides the pressure plate 74, ensuring that the position of the pressure plate 74 remains unchanged when it moves vertically. When the pressure plate 74 moves vertically downward, it contacts the surface of the base 1 through the anti-slip pad 76, thereby reinforcing the position of the turntable 2, locking the position of the turntable 2, and preventing the turntable 2 from shifting due to vibration during pressing. When the pressure plate 74 moves vertically upward, it can release the lock on the turntable 2, and the output shaft of the motor 3 can drive the turntable 2 to rotate, thereby changing the position of the workpiece.

[0022] In this invention, during use, rotating the upper gear 66 causes the lower gear 64 to rotate, thereby facilitating the rotation of the bidirectional threaded rod 61 in the slide groove 5. This drives the two sets of L-shaped support plates 62 to move towards each other or away from each other, allowing the distance between the two sets of limiting blocks 63 to be adjusted to accommodate the sidewall limits of different sized automotive steering knuckles. The steering knuckle is then clamped and fixed by the clamp 4. The motor 3 drives the turntable 2 to rotate through its output shaft, turning the mounting hole on the automotive steering knuckle directly below the welding head of the ultrasonic welding machine. The bushing is then inserted into the mounting hole and pressed in by a hydraulic press.

[0023] Before pressing, the screw 72 is rotated by rotating the wheel 73, and the pressure plate 74 is moved vertically downward. The anti-slip pad 76 contacts the surface of the base 1, thereby reinforcing the position of the turntable 2 and locking the position of the turntable 2 to prevent the turntable 2 from shifting due to vibration during pressing.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
