Technical Field

[0001] This utility model relates to the field of broaching technology, specifically to an adjustment device for a broaching machine for ultra-large bearing bush mating plane. Background Technology

[0002] Bearing shells are sliding bearings used in parts such as crankshaft journals in engines. They are made of a bimetallic steel strip with a steel strip as the substrate and a layer of bearing alloy attached to the surface, and are produced through a series of processes. This bearing alloy is usually Babbitt alloy, aluminum-tin alloy, and copper-lead alloy. The inner circle of the bearing shell is mainly machined by two methods: boring and broaching. The broaching process is used for the mating plane of the bearing shell, which has certain technological characteristics and advantages.

[0003] Currently, when processing oversized bearing bushes using broaching machines, a common problem arises: after the bearing bushes are placed, adjustments to their position or machining angle are needed. Oversized bearing bushes are large in size and weight, requiring workers to frequently climb ladders to adjust their position. Furthermore, the weight of the bearing bush necessitates significant effort to move it, leading to substantial physical exertion. The difficult and time-consuming adjustment process, requiring considerable time and energy to move the workpiece and change angles each time, significantly increases preparation time and reduces processing efficiency. Moreover, climbing large workpieces for adjustments poses a risk of falls, compromising worker safety. Utility Model Content

[0014] 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.

[0015] Please see Figure 1-5 As shown, an adjustment device for a broaching machine for ultra-large bearing bushes includes a bearing bush placement platform 1. The top of the bearing bush placement platform 1 is provided with a receiving groove 2, and an ultra-large bearing bush body 3 is arranged inside the receiving groove 2. Support seats 4 are provided on the left and right sides of the bottom of the bearing bush placement platform 1, and an adjustment structure 5 is movably connected inside the support seat 4. A movable plate 6 is fixed on the top of the adjustment structure 5, and the top of the movable plate 6 is fixedly connected to the bottom of the bearing bush placement platform 1. A fixed frame 7 is fixed above the surface of the bearing bush placement platform 1, and the fixed frame 7 is U-shaped. Fine adjustment structures 8 are fixed on the left and right sides above the fixed frame 7. Hydraulic cylinders 9 are fixed on the left and right sides of the fixed frame 7, and one end of the output shaft of the hydraulic cylinder 9 passes through the interior of the fixed frame 7 and is fixed with a clamping plate 10.

[0016] The adjustment structure 5 includes a motor 51, a lead screw 52, ​​and a moving block 53. The motor 51 is fixed to the rear side of the inner wall of the support base 4. The lead screw 52 is rotatably connected to the front side of the inner wall of the support base 4, and the rear end of the lead screw 52 is fixedly connected to the front end of the output shaft of the motor 51. The moving block 53 is threadedly connected to the front side of the surface of the lead screw 52, ​​and the top of the moving block 53 is fixedly connected to the bottom of the movable plate 6. A guide groove 11 is provided at the bottom of the inner wall of the support base 4, and a guide block 12 is fixed at the bottom of the moving block 53. The lower part of the guide block 12 extends to the guide... The interior of the groove 11 is slidably connected to the inner wall of the guide groove 11. When the operator turns on the motor 51 at the rear, the output shaft of the motor 51 will drive the lead screw 52 at the front to rotate, thereby causing the moving block 53 to move. Through the setting of the guide groove 11 and the guide block 12, the moving block 53 can be guided, so that the moving block 53 can smoothly drive the upper movable plate 6 to move, and adjust the position of the oversized bearing body 3 inside the receiving groove 2 back and forth, so that the flat broaching machine can perform subsequent processing on the oversized bearing body 3.

[0017] The fine-tuning structure 8 includes a hydraulic rod 81, a connecting shaft 82, and a pressing adjustment plate 83. The hydraulic rod 81 is fixed on the left and right sides of the top of the fixed frame 7, and the bottom end of the output shaft of the hydraulic rod 81 extends into the interior of the fixed frame 7. The connecting shaft 82 is fixed on the bottom end of the output shaft of the hydraulic rod 81. The pressing adjustment plate 83 is located on the left and right sides above the oversized bearing body 3, and the top of the pressing adjustment plate 83 is hinged to the bottom end of the connecting shaft 82. The inner wall of the receiving groove 2 is V-shaped, and brackets 13 are fixed on the front and rear sides of the bottom of the inner wall of the receiving groove 2. Rollers 14 are rotatably connected to the top of the brackets 13. The rollers 14 contact the bottom of the oversized bearing body 3 and are in contact with the oversized bearing body 3. The rollers are connected in a rolling manner. When the worker moves the oversized bearing body 3 into the receiving groove 2 and finds that the processing angle of the oversized bearing body 3 needs to be finely adjusted, the worker can open the hydraulic rods 81 on both sides above the fixing frame 7 according to the processing situation. When the output shaft of the right hydraulic rod 81 is pushed out, the output shaft of the left hydraulic rod 81 is retracted. The right pressing adjustment plate 83 descends and pushes the oversized bearing body 3 below to move. The left pressing adjustment plate 83 will move away from the oversized bearing body 3. The roller 14 below will lift the bottom of the oversized bearing body 3, making it convenient for the pressing adjustment plate 83 to adjust the processing angle of the oversized bearing body 3.

[0018] The clamping plate 10 is U-shaped, and the inner wall of the clamping plate 10 is covered with reinforcing pads 15 made of wear-resistant rubber. When the operator places the oversized bearing body 3 into the receiving groove 2, the output shaft of the hydraulic cylinders 9 on both sides will push the clamping plate 10 to move, so that the clamping plate 10 clamps and positions the oversized bearing body 3, preventing the oversized bearing body 3 from moving during processing. The setting of the reinforcing pads 15 can improve the clamping and positioning effect of the oversized bearing body 3. When it is necessary to make a fine adjustment to the processing angle of the oversized bearing body 3, the clamping plate 10 needs to be temporarily moved away from the oversized bearing body 3.

[0019] Working principle: First, the operator uses a hoisting device to smoothly place the oversized bearing body 3 into the receiving groove 2 at the top of the bearing placement platform 1. Because the inner wall of the receiving groove 2 is V-shaped, and brackets 13 are fixed on both the front and rear sides of its bottom, the rollers 14 on the top of the brackets 13 contact the arc-shaped outer surface of the oversized bearing body 3, forming rolling support. This combination of V-shaped groove and rollers 14 can greatly reduce frictional resistance during adjustment while providing initial centering and support for the workpiece. After the workpiece is initially positioned, in order to obtain a precise axial position before broaching, the operator... The operator can start the motor 51 installed on the rear side of the support base 4. The output shaft of the motor 51 will drive the lead screw 52 to rotate. The moving block 53, which is threaded to the front side of the lead screw 52, ​​will then perform precise linear motion under the constraint of the sliding fit between the guide block 12 and the guide groove 11 at the bottom of the support base 4. This will drive the entire bearing bush placement table 1 and the oversized bearing bush body 3 on it to move back and forth together through the movable plate 6 fixed on the top of the moving block 53, thereby adjusting the workpiece processing position. After the axial position is set, if it is found that the splitting plane of the oversized bearing bush body 3 needs to be finely adjusted to ensure that it is absolutely perpendicular to the broaching direction of the broaching machine, then... The fine-tuning structure 8 needs to be activated. At this time, the operator can control the hydraulic rods 81 on the left and right sides of the top of the fixed frame 7 to perform coordinated actions according to the adjustment needs. For example, the output shaft of the right hydraulic rod 81 can be extended while the output shaft of the left hydraulic rod 81 can be retracted synchronously. The connecting shaft 82 at the bottom of the output shaft of the hydraulic rod 81 will push the pressing adjustment plate 83, which is hinged to it, to act on the upper side edge of the oversized bearing body 3. Due to the support of the roller 14 at the bottom, the oversized bearing body 3 will undergo a slight rolling deflection in the V-groove, thereby achieving precise fine-tuning of the workpiece machining angle. This process can be repeated until the angle reaches the required value. After the position and angle are precisely adjusted, in order to ensure the absolute stability of the workpiece during the broaching process, the hydraulic cylinders 9 on the left and right sides of the fixing frame 7 need to be activated. The output shaft of the hydraulic cylinder 9 will push the U-shaped clamping plate 10 to move towards the center. The wear-resistant rubber reinforcing pad 15 bonded to the inner wall of the clamping plate 10 will evenly and firmly clamp the outer surface of the oversized bearing body 3, providing the necessary clamping force while avoiding scratching the workpiece surface. Before a new round of fine adjustment is needed, the hydraulic cylinder 9 needs to be retracted to temporarily remove the clamping plate 10 from the workpiece. Then, the operator can process the oversized bearing body 3 through the broaching machine.
