[0014] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example
[0015] Please see Figure 1-4In this utility model, a ball joint remover for a vehicle steering lever includes a steel pipe 1. An opening 4 is provided on the outer surface of the steel pipe 1. A first end cap 2 is fixedly installed at the bottom end of the steel pipe 1, and a ball joint extraction groove 3 is provided on the bottom surface of the first end cap 2. A second end cap 5 is fixedly installed at the top end of the steel pipe 1, and a through hole 8 is provided on the upper surface of the second end cap 5. A nut 7 is fixedly installed on the upper surface of the second end cap 5. An ejector screw 6 is threaded onto the inner ring of the nut 7. The bottom end of the ejector screw 6 passes through the through hole 8 and extends into the interior of the steel pipe 1. An anti-slip pad 9 is fixedly installed at the top end of the ejector screw 6. By providing an opening 4 on the outer surface of the steel pipe 1, one end of the vehicle steering lever crank arm can be inserted into the interior of the steel pipe 1 through the opening 4. The ball joint is removed by providing an anti-slip pad 9 on the upper surface of the second end cap 5. The cap 7 is installed so that the outer surface of the ejector screw 6 is threadedly connected to the inner ring of the cap 7, allowing the operator to change the position of the ejector screw 6 when rotating it. By installing an anti-slip pad 9 on the top of the ejector screw 6, the friction at the top of the ejector screw 6 can be effectively increased, preventing slippage when rotating the ejector screw 6. By opening a through hole 8 on the upper surface of the second end cap 5, the bottom end of the ejector screw 6 can be easily extended into the interior of the steel pipe 1. The ball head on the vehicle steering lever crank arm can be ejected by the ejector screw 6. By installing the first end cap 2 at the bottom end of the steel pipe 1 and opening a ball head extraction groove 3 on the bottom surface of the first end cap 2, the ball head ejected by the ejector screw 6 can be easily removed from the interior of the steel pipe 1 through the ball head extraction groove 3. Example
[0016] Both the first end cap 2 and the second end cap 5 are made of steel plate, and the steel pipe 1 is made of No. 45 steel. The width of the opening 4 is not less than the lateral thickness of the vehicle steering tie rod crank arm, and the length of the opening 4 is not less than the longitudinal thickness of the vehicle steering tie rod crank arm. The first end cap 2 and the steel pipe 1 are fixed by welding, and the second end cap 5 and the steel pipe 1 are fixed by welding. The first end cap 2 and the second end cap 5 are the same size, and the thickness of both the first end cap 2 and the second end cap 5 is greater than 8 mm. The outer diameter of the first end cap 2 and the outer diameter of the second end cap 5 are the same as the outer diameter of the steel pipe 1. The steel pipe 1 is made of No. 45 steel with a diameter of 80 mm and a length of 150 mm. The width of the opening 4 is 15 mm, which is suitable for most vehicle steering tie rods. The thickness of the tie rod arm allows one end of the vehicle steering tie rod arm to extend into the interior of the steel pipe 1 through the opening 4, facilitating the subsequent removal of the ball head. The first end cap 2 is welded to the bottom end of the steel pipe 1, and there are no gaps at the weld between the first end cap 2 and the bottom end of the steel pipe 1, effectively ensuring the stability of the connection between the first end cap 2 and the steel pipe 1 and preventing the first end cap 2 from falling off the bottom of the steel pipe 1 during operation. Similarly, the second end cap 5 is welded to the top end of the steel pipe 1, and there are no gaps at the weld between the second end cap 5 and the top end of the steel pipe 1, thus ensuring the stability of the connection between the second end cap 5 and the steel pipe 1 and effectively preventing the second end cap 5 from falling off the top end of the steel pipe 1 during operation.
[0017] The nut 7 is fixed to the second end cap 5 by welding. The axis of the nut 7 is collinear with the axis of the steel pipe 1. The diameter of the ball head ejection groove 3 is not less than the maximum diameter of the ball head to be disassembled. The center of the ball head ejection groove 3 is collinear with the axis of the steel pipe 1. The anti-slip pad 9 is made of rubber. By welding the nut 7 and the second end cap 5 together, the tightness of the connection between the nut 7 and the second end cap 5 can be effectively guaranteed. There are no gaps at the weld between the nut 7 and the second end cap 5, which can effectively guarantee the stability of the connection between the nut 7 and the second end cap 5. Because the axis of the nut 7 is collinear with the axis of the steel pipe 1, the ejector screw 6 can always be at the axis of the steel pipe 1 during the movement, thus ensuring the ejection. The bottom end of screw 6 can contact the ball head, thus facilitating the ejection of the ball head from the vehicle-direction tie rod arm. The centerline of the ball head ejection groove 3 is collinear with the axis of the steel pipe 1, and the vertical drop of the ball head ejection groove 3 is greater than the maximum diameter of the ball head to be disassembled. After the ejector screw 6 ejects the ball head from the vehicle-direction tie rod arm, the ball head can be removed from the inside of the steel pipe 1 through the ball head ejection groove 3. The rubber anti-slip pad 9 has excellent anti-slip performance and good wear resistance. The fine texture on its surface can increase the friction between the pad and the contact surface. The rubber anti-slip pad 9 can still maintain a good anti-slip effect after long-term use. This durability means that the anti-slip pad 9 has a long service life, which can reduce the frequency of replacement and costs.
[0018] The working principle of this application is: First, the worker aligns the opening 4 on the outer surface of the steel pipe 1 with the direction lever arm where the ball head to be disassembled is located. Then, the worker moves the device so that one end of the direction lever arm passes through the opening 4 and extends into the interior of the steel pipe 1. The worker then aligns the bottom end of the ejector screw 6 with the nut 7. The worker then rotates the ejector screw 6. With the cooperation of the ejector screw 6 and the nut 7, the ejector screw 6 gradually extends into the interior of the steel pipe 1 as it rotates. When the bottom end of the ejector screw 6 contacts the ball head, the worker can continue to rotate the ejector screw 6 with the help of a wrench or pneumatic wrench. The continuous rotation of the ejector screw 6 gradually ejects the ball head. When the ball head is completely ejected from the lever arm, it falls out of the steel pipe 1 through the ball head ejection groove 3.
