Lower ball jointer (lower ball press-fitting pliers)

Abstract

We offer a lower ball jointer (lower ball press-fitting pliers) that drastically simplifies the replacement process and reduces work time by allowing you to press-fit the lower ball in just a few seconds with a single hand grip. [Solution] By welding a ring with an inner diameter of 36.5 mm to the tip of the pliers, which is compatible with the lower ball joints of many automobiles, the pliers allow for the press-fitting of the lower ball joint, which is required for vehicle inspections, to be done with just one hand. If the lower ball joint or tie rod end boot is torn, it must be replaced during vehicle inspections, otherwise the vehicle will not pass inspection. Replacing and press-fitting the lower ball joint and tie rod end boot is a process that requires using pliers in each hand to pinch and insert the parts little by little, and it takes 5 to 10 minutes, sometimes even longer. Often, both sides are replaced as a set, so shortening the work time is a challenge.

Description

Technical Field

[0001] This invention relates to a plier with a ring for press-fitting a lower ball welded to the tip of the main body.

Background Art

[0002] During vehicle inspection and maintenance, replacing a broken lower ball is an essential task. Generally, when press-fitting the lower ball, two pliers are used and the position grasped by both hands is changed little by little for press-fitting. Therefore, even a skilled worker takes about 5 minutes for this operation, and an inexperienced worker often takes more than 10 minutes.

Summary of the Invention

Problems to be Solved by the Invention

[0003] For the cover press-fitting operation of the lower ball joint, since pliers are held in both hands and the position pinched is shifted little by little, it takes about 5 minutes for a skilled worker and more than 10 minutes for an inexperienced worker. Furthermore, the lower ball is often replaced at two locations on the left and right, and the tie rod ends are also often replaced simultaneously on the left and right, quadrupling the working time. Many vehicle inspection and maintenance factories are tasked with increasing the number of operations, and this invention dramatically shortens and improves the working time.

Means for Solving the Problems

[0004] In this invention, a ring with an inner diameter of about 36.5 mm that can hold the lower ball is welded to the tip of the plier. Therefore, in the past, an operation was performed with pliers held in both hands, but in this invention, one hand becomes free, directly supports the lower ball, and it is possible to perform press-fitting instantly just by gripping with the other hand, solving the problem by significantly shortening the time.

Effects of the Invention

[0005] A task that previously took 5 to 10 minutes can be completed in just 5 seconds with our school's proposal, resulting in a time reduction of 10 to 20 minutes for both sides, and approximately 20 to 40 minutes if the press-fitting of the tie rod end boots is also included. [Brief explanation of the drawing]

[0006] [Figure 1] This is a side view of the lower ball jointer of the present invention. A ring for holding the lower ball is welded to the tip of the pliers. [Figure 2] This is a rear view from above. When the pliers are viewed from directly above, the arm is located almost in the center of the circle. The arm section is rounded to prevent damage to the vehicle body when pressing in the lower ball. [Figure 3] This is an example of the process. Apply grease, set the lower ball, and simply grip it with the lower ball press-fitting pliers of this invention and squeeze to complete the press-fitting. [Modes for carrying out the invention]

[0007] A ring for holding the lower ball is welded to the tip of a conventional pair of pliers. The inner diameter of the ring is approximately 36.5 mm, a size that fits most lower balls in Japanese cars. When viewed from directly above, the arm is located almost in the center of the circle. The arm is rounded to prevent damage to the vehicle body when pressing in the lower ball. By reusing spring-loaded pliers, work efficiency is improved. [Examples]

[0008] As shown in Figure 3, this is a work diagram illustrating an example of using the lower ball jointer of the present invention. By applying grease to the joint, placing the lower ball on top, inserting the lower ball into the ring of the lower ball jointer of the present invention shown in Figures 1 and 2, and squeezing it, the lower ball can be pressed in in an instant.

Claims

[Claim 1] By welding a ring with an inner diameter of 36.5 mm to the tip of the pliers, which is compatible with the lower ball bearings of many automobiles, these pliers allow for the press-fitting of the lower ball bearings required for vehicle inspections and maintenance to be done with just one hand.
