Description

Technical Field

[0001] This utility model relates to the field of ball joint processing technology, and in particular to a positioning device for processing anti-slip polyurethane ball joints. Background Technology

[0002] A ball joint is a mechanical connection component capable of multi-directional rotation, named for its core structure resembling the fit between a sphere and a socket. It mainly consists of a sphere, a socket, and related connecting components. The sphere can rotate freely within the socket, and the connecting components connect the ball joint to other mechanical structures. In modern industrial production, anti-slip polyurethane ball joints are widely used as important mechanical connection components in the automotive, aerospace, and other fields. During their manufacturing process, precise positioning is crucial to ensuring the dimensional accuracy and surface quality of the ball joint.

[0003] Existing ball joints are often machined by turning. First, the connecting parts are clamped and one end of the ball joint is machined to form a spherical surface. Then, the spherical end is clamped and machined. During the machining process, the machined end face of the ball joint needs to be changed. In actual operation, after one end of the ball joint is machined, manual assistance is required to change the machined end face, which not only affects efficiency but also easily affects the clamping and positioning accuracy of the ball joint, resulting in a decrease in the product qualification rate of the ball joint. In view of this, this application proposes an anti-slip polyurethane ball joint machining and positioning device. Utility Model Content

Rotating frames are rotatably connected to the inner sides of both support rods. A first motor is fixedly mounted on the outer side of each support rod, and the first motor drives the corresponding rotating frame to rotate.

Clamping mechanisms are mounted on both the rotating plate and the fixed plate.

[0007] Preferably, each clamping mechanism includes a turntable, and multiple turntables are rotatably connected to the sides of a fixed plate and a rotating plate at corresponding positions.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] This utility model provides a technical solution: such as Figure 1-5 As shown, the anti-slip polyurethane ball joint processing positioning device includes a positioning table 1. Two support rods 2 are symmetrically installed on the top surface of the positioning table 1. A fixed plate 3 is installed on the top surface of the two support rods 2. A rotating frame 5 is rotatably connected to the inner sides of the two support rods 2. A first motor 4 is fixedly installed on the outer side of each support rod 2. The first motor 4 drives the rotating frame 5 at the corresponding position to rotate. Two second electric push rods 20 are symmetrically installed on the top surface of the rotating frame 5. An assembly seat 21 is installed at the bottom end of each second electric push rod 20. A rotating plate 6 is rotatably connected to the two assembly seats 21. A third motor is installed in each assembly seat 21. The output shafts of the two third motors are coaxially connected to the two ends of the rotating plate 6. A clamping mechanism is installed on both the rotating plate 6 and the fixed plate 3.

[0023] The ball joint's spherical surface or connecting part can be clamped by the clamping mechanism. When one end of the ball joint is being machined, the end of the connecting part can be clamped to the bottom end of the ball joint by the clamping mechanism of the fixed plate 3. The first motor 4 drives the rotating plate 6 to rotate to one side of the support rod 2, providing space for the top of the ball joint to be machined. After the top of the ball joint is machined, the rotating plate 6 can be reset, and the second electric push rod 20 drives the clamping mechanism on the rotating plate 6 to clamp the top end of the ball joint. Then, the third motor in the mounting base 21 drives the rotating plate 6 to rotate, thereby rotating the ball joint clamped on the rotating plate 6 and setting the bottom end of the ball joint vertically upward, which facilitates the re-machining of the bottom end of the ball joint and eliminates the need for manual assistance in changing the machining end face of the ball joint, thus increasing machining efficiency.

[0024] Furthermore, each clamping mechanism includes a turntable 15, and multiple turntables 15 are rotatably connected to the sides of the corresponding fixed plate 3 and rotating plate 6. Multiple sliding grooves 8 are symmetrically formed on the outer sides of both the fixed plate 3 and rotating plate 6. A movable seat 9 is slidably connected within each sliding groove 8. An arc-shaped airbag 10 is installed on the outer side of each movable seat 9. A first electric push rod 11 is fixedly installed on the outer side of each movable seat 9, and a clamping plate 12 is installed at the other end of each first electric push rod 11. Multiple arc-shaped grooves 16 are symmetrically formed on each turntable 15, and a clamping plate 12 is fixedly installed on the outer side of each movable seat 9. Positioning rods 18 are provided, and each positioning rod 18 is movably connected in the corresponding arc groove 16. The outer side of the fixed plate 3 and the rotating plate 6 are provided with a rotating mechanism, and the rotating mechanism drives the corresponding turntable 15 to rotate. Through the rotation of the turntable 15, each moving seat 9 can slide towards the center of the turntable 15 through the positioning rods 18 and the arc groove 16, thereby ensuring the concentric clamping of the ball joint. The arc airbag 10 facilitates the stable clamping of the spherical surface of the ball joint. The first electric push rod 11 and the clamping plate 12 are used to stably clamp the connecting parts on the ball joint, thereby ensuring the clamping stability of the ball joint.

[0025] Furthermore, each rotating mechanism includes a gear ring 17, and each gear ring 17 is installed on the outer side of the corresponding turntable 15. U-shaped plates 13 are fixedly installed on the sides of both the fixed plate 3 and the rotating plate 6. A second motor 14 is fixedly installed on the outer side of each U-shaped plate 13. A drive gear 19 is installed on the output shaft of each second motor 14, and each drive gear 19 meshes with the corresponding gear ring 17 to facilitate the slow rotation of the turntable 15.

[0026] Furthermore, both the fixed plate 3 and the rotating plate 6 have positioning grooves 7 on their outer sides, and each positioning groove 7 is concentrically set with the turntable 15 corresponding to the position, which facilitates the spherical auxiliary positioning of the ball joint.

[0027] Furthermore, an end cap is fixedly installed at one end of each positioning rod 18, and the diameter of each end cap is greater than the diameter of the positioning rod 18 to prevent the positioning rod 18 from dislodging from the arc groove 16.

[0028] Furthermore, each of the second motor 14, the third motor, and the first motor 4 is a conical rotor motor, whose output shaft can be locked when the power is off, thereby facilitating the stable limiting of the device installed on its output shaft.

[0029] This utility model provides a non-slip polyurethane ball joint processing and positioning device. The specific working principle is as follows: During operation, the bottom end of the ball joint is first placed on the fixed plate 3 and fixed by the clamping mechanism on the fixed plate 3. Specifically, the second motor 14 in the rotating mechanism drives the drive gear 19 to rotate, which in turn drives the gear ring 17 and the turntable 15 to rotate. When the turntable 15 rotates, the positioning rod 18 slides in the arc groove 16, causing the moving seat 9 to move towards the center of the turntable 15. The first electric push rod 11 pushes the clamping plate 12 to clamp the ball joint connector, thereby achieving stable clamping.

[0030] Next, the top of the ball joint can be machined by turning to achieve spherical machining. After the spherical surface of the top of the ball joint is machined, the first motor 4 drives the rotating frame 5 to rotate, which in turn drives the rotating plate 6 and the ball joint to rotate above the support rod 2. After the top machining is completed, the second electric push rod 20 extends, so that the clamping mechanism on the rotating plate 6 approaches the top of the ball joint and clamps it. Specifically, the first electric push rod 11 clamps the connecting part, while the arc-shaped airbag 10 fits against the spherical surface of the ball joint to assist in clamping the spherical surface machined by the ball joint. At this time, the third motor in the mounting base 21 drives the rotating plate 6 to rotate, adjusting the bottom end of the ball joint to be vertically upward, which facilitates the bottom end machining. Since the first motor 4, the second motor 14 and the third motor are all conical rotor motors, the output shaft locks when the power is off, which can ensure that the ball joint remains stable during the machining process. The whole process does not require manual assistance to change the machining end face of the ball joint, which greatly improves the machining efficiency.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
