Description

Technical Field

[0001] The utility model relates to the technical field of positioning equipment, in particular to a switching mechanism and a flexible positioning equipment. Background Art

[0002] The flexible positioning mechanism is an innovative mechanical technology in the automotive industry that involves the use of flexible positioning and geometric shape design to achieve precise position control and movement. Currently, most flexible positioning mechanisms use elastic elements and mechanisms to achieve the goal of flexible positioning. These mechanisms usually include springs, curved rods, flexible rods, etc., and their design and arrangement can achieve specific movement and position control. By replacing all kinematic pairs or eliminating traditional hinges through flexible movement, the flexibility is relatively evenly distributed throughout the mechanism, which can achieve precise position control and movement. The spatial position of the positioning mechanism can also be adjusted by a structural design that matches a telescopic support mechanism and a rotatable sliding clamping mechanism, and the positioning of the part can be achieved through the process through-holes of the part, increasing the spatial selectivity during operation. However, the specifications of a positioning mechanism are fixed, so the range of workpieces that it can position is limited. In order to expand the positioning range of the flexible positioning mechanism, we propose a switching mechanism and a flexible positioning device. Utility Model Content

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0027] 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. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, with reference to Figures 1 to 5 , which is the first embodiment of the present invention, provides a switching mechanism, including a fixing assembly 100, including a mechanism base 101, and a bearing seat 103 arranged on the mechanism base 101. The arrangement of the mechanism base 101 and the bearing seat 103 facilitates the subsequent installation of the switching assembly 200 and the positioning assembly 300. The switching assembly 200 includes a rotating disk 201 rotatably mounted on the bearing seat 103. The bearing seat 103 is provided with a rotating shaft 203 coaxially fixed with the rotating disk 201, and the end of the rotating shaft 203 away from the rotating disk 201 passes through the bearing seat 103. The end of the rotating shaft 203 passing through the bearing seat 103 can be externally connected to a drive motor. Because the rotating disk 201 is coaxially fixed with the rotating shaft 203, when switching is required, the rotating disk 201 can be controlled to rotate by the driving motor in conjunction with the rotating shaft 203, thereby achieving the switching of the positioning assembly 300. The positioning assembly 300 includes a hook pin cylinder 301 arranged on the rotating disk 201. The setting of the hook pin cylinder 301 facilitates the positioning of the equipment on the workpiece.

[0030] Furthermore, a socket 204 is provided on the rotating disk 201, and a spring pin 205 is provided on the bearing seat 103, and one end of the spring pin 205 slides and extends into the socket 204. Under normal conditions, one end of the spring pin 205 set in the bearing seat 103 will automatically extend into the socket 204, and form a snap-fit ​​relationship with the rotating disk 201 through the socket 204, thereby limiting the rotation of the rotating disk 201 and improving the stability of the positioning assembly 300 on the rotating disk 201 when positioning the workpiece. Figure 3 and Figure 5 As shown, the socket 204 passes through the rotating disk 201. When the rotating disk 201 needs to be driven to rotate, the long pin can be inserted into the socket 204 first, so that one end of the spring pin 205 just leaves the socket 204 and the long pin still stays in the socket 204. At this time, the restriction on the rotating disk 201 is released, so that the position of the positioning component 300 on the rotating disk 201 can be freely adjusted as needed. After the adjustment is completed, the insertion rod is retracted, and under the action of the spring pin 205's own elastic force, one end of it will automatically slide into the socket 204, forming a new engaging relationship with the rotating disk 201.

[0031] Furthermore, an anti-rotation bolt 206 is threadedly connected to one end of the spring pin 205 away from the insertion hole 204. The end of the anti-rotation bolt 206 away from the spring pin 205 passes through the bearing seat 103 and is coaxially fixed with an anti-rotation block 207. A limiting bolt 208 is threadedly connected to the side of the bearing seat 103 away from the rotating disk 201, and the limiting bolt 208 is provided with a limiting block 209 that interlocks with the anti-rotation block 207. The anti-rotation bolt 206, which is threadedly assembled and disassembled on one end of the spring pin 205, forms a mutually fixed relationship with the spring pin 205. The anti-rotation block 207 provided thereon, through the mutual engagement with the limiting block 209, will limit the movement of the spring pin 205, preventing it from rotating easily, thereby reducing the wear of the spring pin 205 caused by frequent rotation and extending its service life.

[0032] Furthermore, a counterweight 202 is provided at the end of the rotating disk 201 opposite to the positioning assembly 300. Due to work needs, not all positioning assemblies 300 may be installed on the rotating disk 201. Therefore, if a positioning assembly 300 is installed at one end of the rotating disk 201 and a positioning assembly 300 is not installed at the opposite end, the balance of the rotating disk 201 may be affected. In this embodiment, a counterweight 202 is provided on the rotating disk 201, and its stability can be improved by adjusting the mass distribution of the rotating disk 201. When the rotating disk 201 is rotating, the counterweight 202 can provide the necessary inertial force to resist external disturbances, thereby maintaining the stable operation of the rotating disk 201. In addition, the counterweight 202 can also be used to adjust the dynamic balance of the rotating disk 201. When the center of gravity of the rotating disk 201 does not coincide with the center of rotation, an unbalanced force will be generated, resulting in vibration. By adding a counterweight 202 at an appropriate position on the rotating disk 201, the center of mass position of the rotating disk 201 can be adjusted to reduce the unbalanced force, thereby reducing vibration and improving the operating efficiency and life of the machine.

[0033] During use, the setting of the rotating disk 201 allows the positioning assembly 300 thereon to be switched according to the different specifications of the positioning workpiece, thereby expanding the positioning range of the equipment and realizing flexible positioning of various automotive workpieces. In addition, the cooperation between the spring pin 205 and the socket 204 limits the rotation of the rotating disk 201, thereby improving the stability of the positioning assembly 300 on the rotating disk 201 when positioning the workpiece.

[0034] Example 2, reference Figures 1 to 5This is the second embodiment of the present utility model. Unlike the previous embodiment, it further includes a driving cylinder 302 provided on the hook pin cylinder 301 for operating the hook pin cylinder 301, and a vent 303 for driving air flow is provided on the driving cylinder 302. An air receiving groove 305 is provided on the rotating disk 201, and an air receiving pipe 1 304 communicating with the vent 303 is provided at one end of the air receiving groove 305 away from the bearing seat 103. The bearing seat 103 is provided with a second air receiving pipe 306 communicating with the air receiving groove 305. During positioning, an external air source can be connected through the second air receiving pipe 306, so that the driving air flow can enter the driving cylinder 302 through the second air receiving pipe 306, the air receiving groove 305, and the first air receiving pipe 304, thereby driving the hook pin cylinder 301 to achieve the positioning operation of the automobile workpiece. In addition, the coordination of the second gas connection pipe 306, the gas connection groove 305 and the first gas connection pipe 304 reduces the volume of the gas pipe used when the driving cylinder 302 is working, leaving more space for welding other process equipment and improving the process feasibility.

[0035] Furthermore, a reinforcement plate 102 is provided on the mechanism base 101. The provision of the reinforcement plate 102 provides a better support effect for the mechanism base 101, ensures the stability of the mechanism base 101 during use, and reduces the risk of the device tipping over or being damaged due to an unstable mechanism base 101.

[0036] When in use, the positioning operation of the automobile workpiece is achieved by cooperating with the driving air flow and the driving cylinder 302, and the cooperation of the air connecting pipe 2 306, the air connecting groove 305 and the air connecting pipe 1 304 is used to reduce the volume of the air pipe used when the driving cylinder 302 is working, thereby improving the practical performance of the equipment.

[0037] Example 3, reference Figure 6 , which is the third embodiment of the present invention, further provides a flexible positioning device. It includes a connecting assembly 400, including a right-angle connecting block 1 401 detachably mounted on the rotating disk 201, and a connecting plate 403 detachably connected to the hook pin cylinder 301, and a right-angle connecting block 2 402 is provided between the connecting plate 403 and the right-angle connecting block 1 401. The hook pin cylinder 301 is assembled and disassembled with the rotating disk 201 through the cooperation of the right-angle connecting block 1 401, the right-angle connecting block 2 402 and the connecting plate 403. Figure 6 The installation style shown in is only one of many embodiments. The right-angle connecting block 1 401, the right-angle connecting block 2 402 and the connecting plate 403 can adjust their respective installation positions as needed to facilitate the positioning of the hook pin cylinder 301 on the automobile workpiece.

[0038] Furthermore, adjustment washers 404 are provided between right-angle connector block 1 401 and right-angle connector block 2 402, between right-angle connector block 2 402 and connecting plate 403, and between connecting plate 403 and hook pin cylinder 301. The provision of adjustment washers 404 disperses stress within the bolted connection, particularly when the connecting components are subjected to uneven loads. The use of adjustment washers 404 reduces localized stress concentration between right-angle connector block 1 401, right-angle connector block 2 402, and connecting plate 403, thus preventing damage. Furthermore, the use of adjustment washers 404 reduces friction between the bolts and the connecting components, facilitating disassembly.

[0039] During use, the right-angle connecting block 1 401, the right-angle connecting block 2 402 and the connecting plate 403 cooperate to realize the loading and unloading with the rotating disk 201, and the installation position between the right-angle connecting block 1 401, the right-angle connecting block 2 402 and the connecting plate 403 can be adjusted as needed, so that the positioning assembly 300 can better position the automobile components.
