Description

Technical Field

[0001] The invention relates to the field of composite material production equipment, in particular to a bidirectional freedom adjustment device for a universal machine base. Background Art

[0002] As we all know, during the debugging and installation of equipment such as compound machines / film coating machines, there are machining errors in the machine base mounting holes on complex machining surfaces or surfaces that cannot be machined by the machine tool. There are single-hole machining errors that cause the machine base mounting position to shift and cannot be installed and used. At the same time, during the debugging and installation of equipment such as compound machines / film coating machines, both the X-direction distance and the Y-direction distance need to be adjusted. The traditional long-slot bolt fixing adjustment mechanism can only be adjusted in one direction and cannot achieve two-way adjustment. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a bidirectional freedom adjustment device for a universal machine base, which can perform both unidirectional adjustment and bidirectional adjustment during the installation of the machine base.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a bidirectional degree of freedom adjustment device for a universal machine base, characterized in that it consists of an eccentric adjustment device and a tapered tube thread set screw. The eccentric adjustment device consists of an eccentric structure composed of a positioning cylinder and an eccentric external thread cylinder. The positioning cylinder and the eccentric external thread cylinder are not concentric. The positioning cylinder is provided with an inner hexagonal groove, and a cylindrical fixed threaded hole is processed at the lower part of the inner hexagonal groove. The fixed threaded hole is concentric with the eccentric external threaded cylinder, and a tapered tube threaded hole is processed downward along the fixed threaded hole. The tapered tube threaded hole is smaller than the fixed threaded hole and passes through the eccentric external threaded cylinder. A cross groove is opened at the bottom end of the eccentric external threaded cylinder, and the tapered tube thread set screw is installed in the tapered tube threaded hole.

[0005] The present invention can also be achieved by the following measures: the groove depth of the cross groove exceeds the tapered pipe thread length of the tapered pipe thread hole. The size and shape of the tapered pipe thread set screw are the same as those of the tapered pipe thread hole.

[0006] The beneficial effects of the present invention are simple structure, easy use, and both unidirectional adjustment and bidirectional adjustment can be achieved without changing the installation method when the machine base is installed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] exist Figures 1 to 4 In the invention, the eccentric adjustment device 4 and the tapered pipe thread set screw 5 are composed of two parts. The eccentric adjustment device 4 adopts an eccentric structure, which is composed of a positioning cylinder 10 and an eccentric external thread cylinder 7. The positioning cylinder 10 and the eccentric external thread cylinder 7 are not concentric, and the eccentricity is s. The positioning cylinder 10 is provided with a hexagonal recessed groove 9, and a cylindrical fixed threaded hole 8 is provided below the hexagonal recessed groove 9. The fixed threaded hole 8 is concentric with the eccentric external thread cylinder 7. A tapered pipe threaded hole 12 is provided downward along the fixed threaded hole 8. The tapered pipe threaded hole 12 is smaller than the fixed threaded hole 8 and passes through the eccentric external thread cylinder 7. A cross groove 11 is provided at the bottom end of the eccentric external thread cylinder 7, and the groove depth of the cross groove 11 exceeds the tapered pipe thread length.

[0016] The tapered tube thread set screw 5 is installed in the tapered tube thread hole 12 of the eccentric adjustment device 4, and the size and shape of the tapered tube thread set screw 5 are the same as those of the tapered tube thread hole 12 of the eccentric adjustment device 4. When the tapered tube thread set screw 5 is tightened and screwed in, under the joint action of the conical surfaces of the two, the cross groove 11 at the bottom end of the eccentric external thread cylinder 7 is deformed and expanded outward.

[0017] The invention describes a bidirectional freedom adjustment device for a universal machine base, and the method of use is as follows: Figure 5 , Figure 6 As shown:

[0018] Pre-install several eccentric adjustment devices 4 in the threaded holes that have been processed on the base, install the universal machine base 3 with the long slotted holes processed on the base, and install the eccentric adjustment devices 4 in the long slotted holes processed on the universal machine base 3. Adjust the eccentric angle of the eccentric adjustment device 4 through the hexagonal recessed groove 9 in the eccentric adjustment device 4, and then adjust the X-direction position (the X-direction adjustment range is 2S). After the X-direction position adjustment is completed, tighten the tapered tube threaded set screw 5 in the eccentric adjustment device 4 to deform the cross groove 11 at the bottom of the eccentric external threaded cylinder 7, expand outward, contact the threaded hole on the base and apply interaction force, increase the friction between the base and the threads of the eccentric adjustment device 4. Make it impossible for the eccentric adjustment device 4 to rotate relative to the base. Fix the X-direction spacing between the universal machine base 3 and the base. Then adjust the Y position by adjusting the processed long slotted hole of the universal base 3 (the Y adjustment range is Z). When the Y position adjustment is completed, install the flat washer 2 on the universal base and fasten the bolt 1 with the fixed threaded hole 8 of the eccentric adjustment device 4. The universal base 3 and the base are fixed by the pre-tightening force of the flat washer 2 and the bolt 1 to complete the two-way freedom adjustment of the X and Y directions.
