Description

Technical Field

[0001] This utility model relates to the field of ball joint processing technology, and in particular to a positionable polyurethane ball joint processing auxiliary device. Background Technology

[0002] In many fields such as mechanical manufacturing and automation equipment, polyurethane ball joints are widely used in key parts such as joint connections and transmission mechanisms due to their good elasticity, wear resistance and shock absorption performance. The processing quality directly affects the operational stability and service life of the equipment. In the processing of polyurethane ball joints, positioning and clamping are extremely critical links, and professional processing auxiliary equipment is needed to ensure the positional accuracy and stability of the ball joint during processing.

[0003] Currently, most of the existing auxiliary equipment for polyurethane ball joint processing on the market adopts a traditional fixed clamp structure, which is difficult to adjust flexibly according to ball joints of different sizes and shapes, resulting in poor adaptability. Although some equipment has certain adjustment functions, it is insufficient in terms of positioning accuracy. During the processing, the ball joint is prone to displacement and deformation due to uneven clamping force or inaccurate positioning, resulting in the dimensional accuracy and geometric tolerance of the processed ball joint failing to meet the high-precision design requirements, and a high scrap rate. Therefore, it is necessary to propose a positioning-enabled auxiliary equipment for polyurethane ball joint processing to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positionable polyurethane ball joint processing auxiliary device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positionable polyurethane ball joint processing auxiliary device includes a base. Two sets of adjusting frames are fixedly connected to the upper end of the base. The two sets of adjusting frames are symmetrically arranged, and a slider is slidably connected between the two sets of adjusting frames. An electric telescopic rod is fixedly connected to the outer wall of each slider. A moving frame is fixedly connected to the end of the telescopic section of the electric telescopic rod. A placement groove is opened at the midpoint of the base. The inner wall of the placement groove is arc-shaped. Two sets of fixing plates are fixedly connected to the outer wall of the moving frame. Two sets of clamping plates are rotatably connected between the two sets of fixing plates, forming a V-shaped angle. Two sets of moving blocks are slidably connected inside the moving frame. The two sets of moving blocks are connected to the two sets of clamping plates through connecting blocks. The two ends of the connecting blocks are rotatably connected to the moving blocks and clamping plates, respectively. A drive mechanism for driving the moving blocks is installed inside the moving frame.

[0007] Preferably, the driving mechanism includes two sets of threaded rods rotatably connected within the movable frame, and the two sets of movable blocks are respectively threaded onto the threaded sections of the two sets of threaded rods, with the thread directions of the two sets of threaded rods being opposite.

[0008] Preferably, multiple sets of limiting rods are fixedly connected inside the movable frame, and the two sets of movable blocks are slidably connected to the outer walls of the two sets of limiting rods.

[0009] Preferably, a threaded rod is rotatably connected to the bottom of the adjustment frame, and the slider is threadedly connected to the threaded section of the threaded rod.

[0010] Preferably, a limiting rod is fixedly connected to the bottom of the adjustment frame, and the slider is slidably connected to the outer wall of the limiting rod.

[0011] Preferably, the two sets of threaded rods are coaxially fixedly connected, a second motor is fixedly connected to the side wall of the moving frame, and a first motor is fixedly connected to the end face of the adjusting frame. The second motor and the first motor are coaxially fixedly connected to the second threaded rod and the threaded rod, respectively.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model uses two sets of threaded rods with opposite thread directions to drive the moving blocks, which can drive the clamping plate to open and close smoothly, applying uniform clamping force to the ball joint from two directions. At the same time, the arc surface of the placement groove provides initial positioning support for the ball joint, forming a multi-directional positioning structure with the V-shaped clamping plate. This effectively solves the problem of ball joint displacement and deformation caused by uneven clamping force and inaccurate positioning in traditional equipment, ensuring that the polyurethane ball joint remains stable during processing, while improving the processing accuracy and product qualification rate of the ball joint.

[0014] 2. This utility model, through components such as threaded rod and slider, combined with the extension and retraction of electric telescopic rod, can achieve precise adjustment of the moving frame and clamping components in the horizontal and vertical directions. Compared with the problem of traditional fixed clamp structures being difficult to adjust flexibly, this device can be widely adapted to various specifications of ball joints, improving the versatility and processing applicability of the equipment.

[0019] 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.

[0020] Reference Figure 1-3 A positionable polyurethane ball joint processing auxiliary device includes a base 1. Two sets of adjustment frames 3 are fixedly connected to the upper end of the base 1. The two sets of adjustment frames 3 are symmetrically arranged. A slider 9 is slidably connected between the two sets of adjustment frames 3. An electric telescopic rod 5 is fixedly connected to the outer wall of each slider 9. A movable frame 6 is fixedly connected to the end of the telescopic section of the electric telescopic rod 5. A placement groove 2 is opened at the midpoint of the base 1. The inner wall of the placement groove 2 is arc-shaped. Two sets of fixing plates 14 are fixedly connected to the outer wall of the movable frame 6. Two sets of clamping plates 13 are rotatably connected between the two sets of fixing plates 14 and form a V-shaped angle. Two sets of moving blocks 10 are slidably connected inside the movable frame 6. The two sets of moving blocks 10 are connected to the two sets of clamping plates 13 through connecting blocks 11. The two ends of the connecting blocks 11 are rotatably connected to the moving blocks 10 and the clamping plates 13 respectively. A drive mechanism for driving the moving blocks 10 is installed inside the movable frame 6.

[0021] Furthermore, the slider 9, in conjunction with the electric telescopic rod 5, enables the flexible movement of the moving frame 6 in three-dimensional space. The electric telescopic rod 5 can precisely control the telescopic distance of the moving frame 6 according to processing requirements, thereby adjusting the relative position of the clamping component and the polyurethane ball joint. The placement groove 2 provides initial positioning and support for the ball joint, reducing its swaying during placement. The two sets of clamping plates 13 form a V-shaped clamping structure, which can clamp the polyurethane ball joint from two directions. Compared with a single-direction clamping method, this effectively improves the stability and reliability of the clamping. The drive mechanism provides power for the movement of the moving block 10, thereby enabling the opening and closing of the clamping plates 13 and completing the clamping and releasing operations of the ball joint.

[0022] The drive mechanism includes two sets of threaded rods 15 rotatably connected within the movable frame 6, and two sets of movable blocks 10 are respectively threadedly connected to the threaded sections of the two sets of threaded rods 15, with the thread directions of the two sets of threaded rods 15 being opposite.

[0023] Furthermore, the drive mechanism adopts two sets of threaded rods 15 with opposite thread directions, which can realize the synchronous reverse movement of the two sets of moving blocks 10, thereby driving the clamping plate 13 to open and close smoothly. Compared with the traditional drive method, it can ensure that a uniform clamping force is applied to the polyurethane ball joint, and avoid deformation or displacement of the ball joint due to uneven clamping force.

[0024] Multiple sets of limiting rods 16 are fixedly connected inside the movable frame 6. Two sets of movable blocks 10 are slidably connected to the outer walls of the two sets of limiting rods 16 respectively. A threaded rod 7 is rotatably connected to the bottom of the adjusting frame 3. A slider 9 is threadedly connected to the threaded section of the threaded rod 7. A limiting rod 8 is fixedly connected to the bottom of the adjusting frame 3. A slider 9 is slidably connected to the outer wall of the limiting rod 8.

[0025] Furthermore, by controlling the rotation of the threaded rod 7, the position of the slider 9 can be flexibly adjusted, driving the moving frame 6 and the clamping components to move horizontally, so as to adapt to the processing requirements of polyurethane ball joints of different sizes.

[0026] Two sets of threaded rods 15 are coaxially fixedly connected. Motor 12 is fixedly connected to the side wall of the moving frame 6. Motor 4 is fixedly connected to the end face of the adjusting frame 3. Motor 12 and Motor 4 are coaxially fixedly connected to threaded rods 15 and 7 respectively.

[0027] In this invention, when the device is used, the operator first places the ball hinge in the placement groove 2 at the midpoint of the base 1. The arc surface of the inner wall of the placement groove 2 fits against the bottom of the ball hinge, providing initial support for the ball hinge and reducing wobbling during placement.

[0028] Next, according to the size and processing requirements of the ball joint to be processed, the operator starts the motor 4 on the end face of the adjustment frame 3. Then the threaded rod 7 rotates, driving the slider 9 to slide along the length of the adjustment frame 3, which in turn drives the electric telescopic rod 5, the moving frame 6 and the clamping parts fixed on its outer wall to be adjusted to the appropriate position in the horizontal direction.

[0029] After the horizontal position adjustment is completed, the operator operates the electric telescopic rod 5. When not activated, the electric telescopic rod 5 maintains a certain length, keeping the moving frame 6 at a distance from the ball joint. After activation, the electric telescopic rod 5 extends and retracts, causing the moving frame 6 to move vertically, so that the clamping component and the ball joint reach the appropriate relative position.

[0030] After the position is adjusted, the operator starts the motor 12 on the side wall of the moving frame 6. The motor 12 drives the two sets of threaded rods 15 coaxially connected inside the moving frame 6 to rotate. Because the threads of the two sets of threaded rods 15 are in opposite directions, the moving block 10 is threadedly engaged with the threaded rods 15, and with the guidance of the limiting rod 16, the two sets of moving blocks 10 slide in opposite directions. The moving block 10 pulls the two sets of clamping plates 13 through the connecting block 11, causing the clamping plates 13 to close towards the ball joint, applying a uniform clamping force to the ball joint from two directions, fixing the ball joint, preventing deformation or displacement of the ball joint, and providing positioning assurance for subsequent processing.

[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.
