Detailed Description
The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.
In the description of the present invention, it should be understood that the terms "front", "back", "left", "right", "up", "down", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 and 2, a fixing device for shaft sleeve production comprises a supporting seat 1, a cylindrical fixing seat 2 is fixed at the top of the supporting seat 1, a driving assembly is arranged in the fixing seat 2, and a plurality of jacking assemblies are slidably arranged on the side wall of the fixing seat 2.
The drive assembly comprises a swivelling lever 3 and a squeezing wheel 4 fixed on the swivelling lever 3. Dwang 3 passes through bearing 5 to be fixed in fixing base 2, and the upper end of dwang 3 passes fixing base 2 and is connected with carousel 6, and threaded connection has locating pin 7 on carousel 6, and constant head tank 8 corresponding with locating pin 7 has been seted up at the top of fixing base 2. Extrusion wheel 4 and dwang 3 coaxial setting, extrusion wheel 4's circumference evenly is provided with a plurality of extrusion flanges 9.
The tight subassembly in top includes tight piece 10 in top and push rod 11, set up a plurality ofly on the lateral wall of fixing base 2 with the spout 12 of tight piece 10 looks adaptation in top, spout 12 is along the circumference evenly distributed of fixing base 2, and all be fixed with reset spring 13 in every spout 12, reset spring 13 and tight piece 10 fixed connection in top are passed to the outer end of push rod 11, push rod 11 the inner then with the extrusion flange 9 butt that corresponds (push rod 11 and extrusion flange 9's butt face are slick and sly contact surface).
