Description

Technical Field

[0001] The present invention relates to the technical field of supporting auxiliary equipment, and in particular to a universal supporting device. Background Art

[0002] A car is made up of numerous assemblies, each of which is composed of numerous sub-components. Because these components are designed for the vehicle body, many assembly parts present assembly difficulties. Furthermore, with the increasing frequency of vehicle upgrades in recent years, the shape of auto parts has become more complex, and the demand for quality has also become increasingly stringent. Coupled with limitations such as size and location, assembly of assemblies requires dedicated assembly tables. These tables are used for assembly, welding, drilling, and other operations, ensuring that parts are free of bending, deformation, and scratches during assembly. More importantly, this improves assembly efficiency and quality.

[0003] The existing solution uses special jigs, which are only used for special parts and cannot meet the needs of parts with different structural sizes. In particular, for different car models, a wide variety of jigs are needed. The following problems exist in the use of jigs: When the assembly environment is restricted, especially for products with limited assembly space and certain weight and toughness requirements, the existing jigs have poor inclusiveness and plasticity, cannot match the use of different parts, and are difficult to operate in a limited space, resulting in difficulty in part assembly and low assembly efficiency. This will bring the following problems to the jig manufacturing industry: 1. There are many jig molds, and different types of jigs need to be maintained for a long time. The consistency of jig molds is poor, resulting in poor product consistency, increased labor costs, and reduced production efficiency. 2. Due to the differences in jigs, the manufacturing cost of jigs increases. 3. When the product design changes, the jig also needs to be modified or even scrapped and remade, which causes waste of raw materials in the production of jigs and is not conducive to energy conservation. Therefore, a jig is needed to solve the existing problems. Summary of the Invention

[0037] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0039] This embodiment provides a universal support device, which includes a support plate assembly, inner and outer ball assemblies, and a bottom support;

[0040] like Figures 1 to 3 As shown, the inner and outer ball assembly includes an outer ball 2 and an inner ball 3. The interior of the outer ball 2 is a spherical cavity, which can be mounted on the inner ball 3 and has a 360° free rotation along the inner ball 3. A slide groove 21 is provided on the outer wall of the outer ball 2. The angle formed by the lines connecting the two ends of the slide groove 21 to the center of the outer ball 2 is greater than 270°; the inner and outer ball assembly also includes a first fixing structure, which is used to fix the rotation position of the slide groove 21 relative to the inner ball 3; the inner ball 3 is fixed to the mounting platform through a bottom support.

[0041] The support plate assembly is slidably connected to the slide groove 21 . The support plate assembly includes a support plate and a second fixing structure. The support plate is used to abut against the surface of the part, and the second fixing structure is used to fix the position of the support plate assembly in the slide groove 21 .

[0042] like Figures 5 to 7 As shown, the horizontal center plane of the inner ball 3 is provided with a accommodating cavity with two through ends, and the first fixed structure is located in the accommodating cavity; the first fixed structure includes a fastening gripper 6 and a separation disc 7, the separation disc 7 is located in the center of the accommodating cavity, and the fastening gripper 6 has two, which are symmetrically arranged on both sides of the separation disc 7; the separation disc 7 is used to push the fastening grippers 6 on both sides to move toward the inner wall of the outer ball 2, and the fastening grippers 6 are used to press the inner wall of the outer ball 2.

[0043] The end of the fastening grip 6 close to the outer ball 2 is arc-shaped, and there is a toothed structure on the outside of the arc. The end of the fastening grip 6 close to the separation disk 7 is V-shaped, and the separation disk 7 is S-shaped. The fastening grip 6 and the separation disk 7 cooperate with each other to fix the relative position of the outer ball 2 and the inner ball 3. After the relative position of the outer ball 2 and the inner ball 3 is fixed, since the slide groove 21 is on the outer wall of the outer ball 2, the rotation position of the slide groove 21 relative to the inner ball 3 is also fixed.

[0044] When the outer ball 2 and the inner ball 3 are fixed, the inner ball 3 drives the two fastening grips 6 to rotate around the separation disk 7, and the S-shaped upper and lower ends of the separation disk 7 respectively abut against the middle of the V-shaped end of the fastening grips 6. The separation disk 7 simultaneously pushes the two fastening grips 6 to move toward the inner wall of the outer ball 2, and the toothed structures on the outer sides of the arc-shaped ends of the two fastening grips 6 are pressed against the inner wall of the outer ball 2; when the outer ball 2 and the inner ball 3 are rotated, the inner ball 3 drives the two fastening grips 6 to rotate around the separation disk 7, and the S-shaped upper and lower ends of the separation disk 7 simultaneously disengage from the middle of the V-shaped ends of the two fastening grips 6. The two fastening grips 6 are no longer subjected to force and are loosened from the inner wall of the outer ball 2.

[0045] To prevent excessive rotation angles, the lengths of the two fastening grips 6 and the ends of the separation disc 7 are designed to be greater than the diameter of the inner ball 3 and less than the outer diameter of the outer ball. When the separation disc 7 rotates until its upper and lower ends in an S-shape abut against the middle of the V-shaped ends of the fastening grips 6, the portion of the fastening grips 6 that extends beyond the surface of the inner ball 3 is between the inner ball 3 diameter and the outer diameter of the outer ball 2. This creates a significant increase in resistance. The greater the resistance, the greater the fastening force, preventing excessive rotation. When the outer ball 2 and inner ball 3 are fixed, the distance between the outer edges of the curved ends of the two fastening grips 6 is greater than 1.2 times the inner diameter of the outer ball 2.

[0046] like Figure 4 As shown, the second fixed structure includes a driven separation block 4 and an active separation block 5. The driven separation block 4 and the active separation block 5 are stacked together and located in the slide groove 21. The side section of the slide groove 21 is an inverted T shape, wherein the active separation block 5 is close to the inner bottom surface of the slide groove 21, and the driven separation block 4 is close to the inner top surface of the slide groove 21.

[0047] The support plate 1 has a central hole for mounting a bolt. The driven and active release blocks 4 and 5 have coaxial central holes for mounting bolts. The central hole of the active release block 5 is an unthreaded blind hole, while the central hole of the driven release block 4 is a threaded through hole. The through hole of the driven release block 4 mates with the threaded portion of the bolt. The bolt passes through the central holes of the support plate 1, driven release block 4, and active release block 5, connecting the support plate 1, driven release block 4, and active release block 5. The blind hole of the active release block 5 forms an interference fit with the lower end of the bolt.

[0048] The driven separation block 4 and the active separation block 5 are both arc-shaped blocks, and are matched with the slide groove 21 on the outer ball 2. The contact surface between the active separation block 5 and the inner bottom surface of the slide groove 21 has a tooth-shaped structure. The driven separation block 4 and the active separation block 5 can slide along the slide groove 21, and drive the support plate 1 to slide when sliding. At this time, the support plate 1 can slide and adjust its position at will in the slide groove 21.

[0049] When the support plate 1 is fixed to the slide groove 21, the bolt is twisted to screw it in the tightening direction, the driven separation block 4 and the active separation block 5 are twisted and abut against the two sides of the slide groove 21, and the active separation block 5 is pushed downward by the bolt. At this time, the driven separation block 4 and the active separation block 5 are separated, and the active separation block 5 is abutted and fixed against the inner bottom surface of the slide groove 21, and the driven separation block 4 is abutted and fixed against the inner top surface of the slide groove 21. At this time, the support plate 1 is fixed relative to the slide groove 21; when the support plate 1 slides along the slide groove 21, the bolt is twisted to screw it in the opposite direction of tightening, and the movement direction of the driven separation block 4 and the active separation block 5 is opposite to the tightening direction, and the driven separation block 4 and the active separation block 5 will be stacked together again.

[0050] Preferably, the support plate 1 can be replaced with different shapes, and even the support plate of the counterpart profiling block of the part can be designed to meet different needs.

[0051] The bottom of the inner ball 3 has a connecting post, which is fixed together as a whole. Rotating the inner ball 3 drives the two fastening grips 6 into contact with the separation disc 7. The connecting post is a cylindrical tube with a through-hole in the middle and anti-slip grooves on the outer surface to increase resistance and facilitate rotation. The inner ball has space inside for overlapping the bottom support, which passes through the through-hole of the connecting post and connects to the separation disc 7. The separation disc 7 is fixed in place, and the inner ball 3 overlaps the bottom support and is fixed to the mounting surface through the bottom support.

[0052] The entire universal support device is made of alloy stainless steel, and the inner wall of the outer ball 2 is made of polyurethane rubber material.

[0053] like Figure 8 、 Figure 9 As shown, a spatial coordinate system is established with the center of the inner ball 3 as the coordinate origin, the straight line where the projection of the slide groove 21 on the horizontal plane is located as the x-axis, the straight line perpendicular to the x-axis on the horizontal plane and passing through the center of the ball as the y-axis, and the straight line in the vertical direction passing through the center of the ball as the z-axis. The outer ball 2 can rotate freely in the horizontal direction of the inner ball 3, and the rotation angle is 360°. The support plate assembly can move 280° along the slide groove 21 with the center of the ball as the center of the circle.

[0054] This embodiment takes the installation of the universal support device to complete the assembly of the front and rear bumper products of the car as an example, and the usage method is as follows:

[0055] Prepare the front and rear bumper products of the car, select several support points around the product frame, and fix the universal support device of this design on the installation table.

[0056] A layer of felt is applied to the support plate 1 to protect the surface of the product. The outer ball 2 is manually moved and the support plate 1 is moved along the chute 21 so that the support plate 1 fits the surface of the product to be supported. After adjusting to the appropriate position, the connecting column is rotated. The connecting column drives the inner ball 3 to rotate, and the inner ball 3 drives the fastening gripper 6 to rotate around the separation disc 7. When the separation disc 7 is rotated to the long side, the two fastening grippers 6 are pushed open, and the teeth on the outer side of the arc-shaped end of the fastening gripper 6 press the inner wall of the polyurethane rubber material of the outer ball 2, so that the inner ball 3 and the outer ball 2 remain fixed in their current positions. Twist the bolt to separate the driven separation block 4 and the active separation block 5, and get stuck in the chute 21. The active separation block 5 will be supported by the bolt, and the teeth on it press the inner wall of the outer ball 2, so that the support plate 1 and the outer ball 2 remain fixed in their current positions. At this time, the universal support device supports the product.

[0057] Finally, after the product assembly is complete, the universal support device is disassembled. Reverse the bolt rotation to re-engage the driven separation block 4 and the active separation block 5. Rotate the connecting column again, and the inner ball 3 drives the tightening grip 6 to rotate around the separation disc 7 to the short side of the separation disc 7. The tightening grip 6 retracts, and the inner ball 3 rotates freely. The universal support device is then disassembled.

[0058] In the present invention, terms such as "installed," "connected," "connected," and "fixed" should be understood broadly. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; and "connected" may refer to a direct connection or an indirect connection via an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0059] The shapes of the components in the drawings are schematic and may differ from their actual shapes. Terms such as "upper," "lower," "front," and "back" in this patent document are based on the positional relationships shown in the drawings. The corresponding positional relationships may vary depending on the drawings, and should not be construed as limiting the scope of protection.
