Description

Technical Field

[0001] This utility model relates to the field of clamping devices, specifically to a multi-process workpiece clamping device. Background Technology

[0002] Multi-process workpiece clamping devices (also known as multi-functional fixtures or multi-process fixtures) play an important role in modern automobile manufacturing. These devices not only improve production efficiency but also reduce production costs and the labor intensity of workers. Modern multi-process clamping devices can integrate multiple functions, such as welding, dispensing, and inspection, and can complete multiple processes at one workstation. This integrated design greatly simplifies the production line layout and saves space.

[0003] Chinese patent CN117817601A discloses a tooling fixture for the inner ring of a tapered roller bearing. The surfaces of the upper and lower ring supports are curved. The lower ring support is fixed to a second central shaft via several sets of inner folding supports. Threaded grooves are formed at the centers of the first and second central shafts, and adjusting screws are threaded into the internal threads of these grooves. Fixing nuts are located above and below the upper and lower ring supports, respectively. These fixing nuts are threaded onto the outer surface of the adjusting screws. Through the fixture assembly, the upper, lower, and inner folding supports in the device are all made of elastic metal. During the press-fitting process, the inner ring bearing abuts against the curved surfaces of the upper and lower ring supports, causing them to bend inwards. After assembly, the fixture assembly can be removed. However, this device still has the following problems:

[0004] In the multi-stage assembly of roller bearings, the positions of the roller sleeve and the bearing sleeve need to be fixed manually. Then, when installing the roller, the bearing sleeve and the roller sleeve need to be rotated manually to adjust the installation position. Finally, the roller sleeve and bearing sleeve with the roller installed need to be assembled manually. There are many manual operation steps, which is quite wasteful of manpower in busy production processes.

[0005] Based on this, the present invention designs a multi-process workpiece clamping device to solve the above problems. Utility Model Content

[0035] In this invention, in the first process, the operator places the roller sleeve and bearing sleeve above the rotating assembly 21 by pushing the assembly mechanism 3. Then, the bushing clamping assembly 22 and the roller sleeve clamping assembly 23 respectively center and clamp the bearing sleeve and the roller sleeve. In the second process, when the operator finishes assembling each roller, the rotating assembly 21 drives the roller sleeve and bearing sleeve to rotate to the next roller assembly position, saving assembly time. In the third process, after the roller is completely assembled into the roller sleeve, the roller sleeve clamping assembly 23 releases the clamping limit on the roller sleeve, and then the pushing assembly mechanism 3 pushes the roller sleeve and bearing sleeve to assemble.

[0040] In this invention, the operator places the bearing sleeve and roller sleeve on the upper end of the rotating table 211 by pushing the assembly mechanism 3. At this time, cylinder 222 drives clamping block 221 to slide in a limited manner with the rotating table 211 through limiting component 223; multiple clamping blocks 221 cooperate to clamp and fix the bearing sleeve; at the same time, cylinder 232 drives clamping block 231 to slide in a limited manner with the rotating table 211 through limiting component 233; multiple clamping blocks 231 cooperate to clamp and fix the roller sleeve; then the operator transfers the roller into the roller sleeve. For each roller assembled, motor 212 drives the bearing sleeve and roller sleeve to rotate to the next roller installation position through the rotating table 211, which facilitates roller installation and saves assembly time; after assembly, the operator uses both hands to reach under the roller bearing through the two pick-and-place slots 213 to pick up the roller bearing.

[0041] like Figure 2 and Figure 3 As shown, the pushing assembly mechanism 3 includes an assembly component 31, a limiting component 32, and a workpiece placement component 33; the lower end of the assembly component 31 is connected to the upper end of the rotating table 211; the limiting component 32 limits the assembly component 31; both the rotating table 211 and the assembly component 31 are connected to the limiting component 32; the workpiece placement component 33 is installed on the upper end of the rotating table 211; the assembly component 31 is used to push the roller sleeve and the bearing sleeve for assembly; the limiting component 32 is used to limit the assembly component 31; the workpiece placement component 33 is used to place the roller sleeve and the bearing sleeve.

[0045] In this utility model, the operator places the bearing sleeve on the upper end of multiple bearing sleeve placement blocks 332 and the roller sleeve on the upper end of multiple roller sleeve placement blocks 331. The roller sleeve is lower than the bearing sleeve, leaving space for the roller to be placed, so that the roller can be placed easily. After the roller is installed, multiple cylinders 232 push multiple clamping blocks 231 to release the clamping and fixing of the roller sleeve. Cylinder 311 drives the push plate 312 to slide along the limiting slide rod 321. The push plate 312 pushes the roller sleeve upward to assemble with the bearing sleeve. Because the bearing sleeve is heavy, the roller sleeve is pushed into the bearing sleeve to complete the assembly.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
