Description

Technical Field

[0001] This utility model relates to the field of ball bearing assembly equipment technology, and in particular to a ball bearing filling device for turntable production. Background Technology

[0002] The turntable is a crucial component on vehicles such as full trailers, serving functions such as steering, load bearing, and connection between the main frame and subframe. In the manufacturing of turntables, ball bearing installation is a key process to ensure smooth rotation. Currently, the industry commonly uses manual insertion of individual balls into the turntable's raceway through the ball bearing opening. This method has the following drawbacks: 1. The assembly efficiency is extremely low. A person can only operate one or a few balls at a time, which is difficult to meet the needs of mass production. 2. The labor intensity is high. Long-term repetitive single actions can easily lead to human fatigue, which in turn increases the probability of quality problems such as insufficient or excessive filling.

[0003] Therefore, there is an urgent need for a device that can achieve rapid and accurate ball filling in order to solve the problems existing in the prior art. Utility Model Content

[0004] Therefore, it is necessary to provide a ball bearing filling device for rotary table production to address the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides a ball bearing filling device for turntable production, including a sleeve and a push rod. The sleeve has a hollow interior to accommodate the balls to be filled. The push rod is slidably inserted into the sleeve to push out the balls inside the sleeve. A positioning member is fixedly connected to the front end of the sleeve, and the positioning member has at least two protrusions on the end facing away from the sleeve.

The size of the push block is larger than the size of the limiting port, and the limiting port is used to restrict the push block from moving out of the sleeve.

[0007] Preferably, the push block has a positioning groove in the radial direction, and an elastic ball is installed radially at the rear end of the sleeve. The ball of the elastic ball is adapted to the positioning groove and forms a snap-fit ​​engagement. In this way, the push rod can be prevented from moving when loading the ball bearings.

[0008] Preferably, the rear end face of the push block is provided with a first chamfer. With the guiding effect of the first chamfer, the ball can move smoothly to the positioning groove and complete the engagement, realizing the rapid positioning of the push rod.

[0009] Preferably, the rear end of the push rod is fixedly connected to a handle, which facilitates manual gripping and application of force.

[0010] Preferably, a limiting plate is fixed on the push rod, and the limiting plate is located near the handle to limit the contact between the handle and the sleeve and avoid excessive pushing.

[0011] The protrusions are preferably configured as two, and the two protrusions are symmetrically distributed along the axis of the positioning member to improve the stability of docking with the ball filling port of the turntable.

[0012] Preferably, the protrusions are provided as two, and the two protrusions are symmetrically distributed along the axis of the positioning member.

[0013] Preferably, the protrusion has a frustum structure, and the diameter of the front end of the protrusion is smaller than the diameter of its tail end.

[0014] Preferably, the protrusion has a cylindrical structure and a second chamfer at the front end.

Detailed Implementation

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Please see Figures 1 to 8 A ball bearing filling device for rotary table production includes a sleeve 1 and a push rod 2. The sleeve 1 is a hollow cylindrical structure, and its interior is used to accommodate the balls to be filled. The push rod 2 is slidably inserted into the sleeve 1, and a push block 4 is fixedly connected to the front end of the push rod 2 by welding.

[0020] A positioning component 3 is welded and fixed to the front end of the sleeve 1. The end of the positioning component 3 facing away from the sleeve 1 is fixed with two protrusions 31 by welding. The two protrusions 31 are symmetrically distributed along the axis of the positioning component 3 and are used to precisely align with the ball filling port 81 of the turntable 8.

[0021] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 5 The protrusion 31 is designed in a frustum-shaped structure, with the diameter of its front end smaller than that of its rear end. This reduces the difficulty of alignment and insertion, facilitating quick insertion into the positioning hole 82 of the turntable 8. For other embodiments, please refer to... Figure 6 and Figure 7 The protrusion 31 can also be cylindrical, with a second chamfer 311 or a dome 312 at the front end. All of these structures facilitate quick insertion into the positioning hole 82 of the turntable 8.

[0022] When loading the balls, the operator pulls the push rod 2 outward, and then loads a fixed amount of balls into the sleeve 1 to complete the loading preparation; then the two protrusions 31 on the positioning part 3 are aligned and engaged into the positioning hole 82 of the turntable 8, and the front end face of the positioning part 3 abuts against the turntable 8. At this time, the sleeve 1 is aligned with the ball loading port 81 to complete the positioning and docking; the operator applies a forward pushing force to the push rod 2, so that the push rod 2 pushes out the balls in the sleeve 1 and into the ball loading port 81 of the turntable 8.

[0023] In some embodiments, in order to enable the push rod 2 to slide stably in the sleeve 1, a circular limiting port 11 is provided at the rear end of the sleeve 1. The push rod 2 slides with the limiting port 11, and the diameter of the push block 4 is larger than the diameter of the limiting port 11, so that the limiting port 11 can restrict the push block 4 from moving out of the sleeve 1.

[0024] In some embodiments, to facilitate the movement of the push rod 2, a handle 6 is fixedly connected to the rear end of the push rod 2 by means of thread or welding.

[0025] In addition, to prevent excessive pushing, a limiting plate 7 is welded and fixed to the push rod 2 near the handle 6. The diameter of the limiting plate 7 is larger than the diameter of the handle 6, which is used to limit the contact between the handle 6 and the sleeve 1. At the same time, the limiting plate 7 can also prevent the hand holding the handle 6 from contacting the sleeve 1, thus avoiding injury. When the limiting plate 7 contacts the rear end of the sleeve 1, the push rod 2 stops moving, completing one ball filling operation.

[0026] In some embodiments, to prevent the movement of the push rod 2 from affecting the ball bearings inserted into the sleeve 1, an elastic ball bearing 5 is installed radially through the rear end of the sleeve 1, and a positioning groove 41 is provided radially on the push block 4. The positioning groove 41 is adapted to the ball bearing end of the elastic ball bearing 5, and the two can form a snap-fit ​​engagement, thereby fixing the position of the push rod 2. Under the application of a certain external force, the push rod 2 will not move relative to the sleeve 1, which makes it easy to insert a certain amount of ball bearings into the sleeve 1.

[0027] When it is necessary to push the balls out of the sleeve 1, a forward thrust is applied to the push rod 2, which can separate the positioning groove 41 from the ball of the elastic ball 5.

[0028] The rear end face of the push block 4 is provided with a first chamfer 42. When the push rod 2 is pulled in, the ball of the elastic ball 5 can smoothly slide into the positioning groove 41 along the first chamfer 42 at the rear end of the push block 4 to achieve quick positioning and avoid the ball from getting stuck with the rear end face of the push block 4.

[0029] The working process of this embodiment is as follows: The operator holds handle 6 and pulls push rod 2 outward. Push block 4 moves with push rod 2 towards the rear end of sleeve 1. The elastic ball bearing 5 first contacts the first chamfer 42 at the rear end of push block 4, and slides into positioning groove 41 under the guidance of the first chamfer 42, fixing push rod 2 in position. At this time, a certain amount of balls to be filled are loaded into sleeve 1, completing the filling preparation.

[0030] The moving device aligns the two protrusions 31 on the positioning member 3 with and engages them with the ball filling port 81 of the turntable 8, thus completing the positioning and docking.

[0031] The operator grips handle 6 and applies forward force, causing the positioning groove 41 to separate from the ball-bearing end of the elastic ball 5. Push rod 2 drives push block 4 to slide forward along the inner wall of sleeve 1. Push block 4 pushes the balls out of sleeve 1, which are then guided by positioning element 3 and enter the ball filling port 81 of turntable 8. When limit plate 7 contacts the rear end of sleeve 1, push rod 2 stops moving, completing one ball filling operation.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
