Detailed Description
Referring to fig. 1 to 3, an embodiment of the present application provides a thin-walled lining disc type part machining fixture, including a positioning base 1 and a locking mechanism, wherein: elastic clamping pieces 6 are distributed on the front end face of the positioning base 1 along the circumferential direction, and all the clamping pieces 6 jointly form a circular clamping ring 4; the locking mechanism comprises a squeezing disc 2 capable of moving along the axial direction of the positioning base 1, and when the locking mechanism moves along the direction close to the positioning base 1, the squeezing disc 2 gradually contacts with the inner side of the clamping piece 6 and squeezes the clamping piece 6 to bend outwards, so that the clamping ring 4 expands to lock the thin-wall lining disc type part to be processed.
The base 1 and the locking mechanism in this application cooperate with each other, and the base 1 is used for installing and placing the part 3, and the locking mechanism is used for locking and fixing the part 3 on the positioning base 1. Specifically, the front end face of the positioning base 1 is provided with a clamping ring 4 structure, the clamping ring 4 is a circular structure formed by a plurality of clamping pieces 6, and the adjacent clamping pieces 6 are mutually independent. The card 6 is made of elastic material, for example, steel sheet, and can deform to a certain extent when receiving external force. When processing part 3, put part 3 on the terminal surface before the location base 1, make grip ring 4 pass the hole of part 3, then drive locking mechanical system moves to location base 1 direction, this in-process, last extrusion disc 2 of locking mechanical system at first with the contact of 4 inner walls of grip ring, when continuing to move, under the effect of 2 thrusts on extrusion disc, card 6 takes place to deform and outside bending, then grip ring 4 produces the inflation, be equivalent to the external diameter that has increased grip ring 4, 4 external diameter increase backs of grip ring, contact and the crescent contact force with the hole of part 3, thereby effectively lock part 3. Because the card 6 is the circumference distributes among this device, can contact part 3 simultaneously and provide even pressure, consequently part 3 atress is even, and the clamp force is also controlled easily to can improve the qualification rate of product, reduce the processing degree of difficulty.
Referring to fig. 2 and 3, an annular body is arranged on the front end surface of the positioning base 1, and first notches 11 are uniformly formed in the annular body along the axial direction, so that the clamping pieces 6 are formed between the adjacent first notches 11; a second gap 12 is formed in the position, which is in contact with the positioning base 1, of each card 6 along the circumferential direction, and the second gaps of the two adjacent cards 6 are communicated with the first gaps 11 between the two cards 6. That is, the machining process of the clamping ring 4 can be regarded as that a ring body is firstly arranged on the front end surface of the positioning base 1, and then the first notch 11 and the second notch 12 are formed by cutting. The first notches 11 ensure that all the cards 6 are relatively independent, and the second notches 12 reduce the connection between the cards 6 and the positioning base 1 so as to facilitate the bending deformation of the cards.
In order to better enable the clamping ring 4 to expand under the thrust of the pressing disk 2, in one embodiment, the inner side surface 13 of the clamping piece 6 is a slope inclined to the axial direction of the positioning base 1, so that the inner surface 5 of the clamping ring 4 is a conical surface.
Referring to fig. 1 and 3, the inner surface 5 of the clamping ring 4 formed by all the clamping pieces 6 is a conical surface, which is equivalent to that the inner hole is a conical hole. The conical inner surface 5 can more easily be bent outwards during pressing when the circular pressing disk 2 is pressed.
In another embodiment, the pressing disk 2 is provided with a ring of conical surfaces on its circumference. In this embodiment, the inner surface 5 of the clamping ring 4 may or may not be a conical surface at the same time. As long as at least one of the outer circumference of the pressing disk 2 and the inner surface 5 of the clamping ring 4 is provided with a tapered surface, the expansion can be performed more conveniently and smoothly.
Referring to fig. 1, the locking mechanism further includes a hexagonal boss 7 coaxially disposed at the front end of the extrusion disk 2 and a threaded rod 8 disposed at the rear end of the extrusion disk 2, and a threaded hole 9 matched with the threaded rod 8 is processed on the positioning base 1 along the axis. In actual use, after the part 3 is placed, the hexagonal boss 7 at the front end of the locking mechanism is rotated by a wrench to drive the threaded rod 8 to rotate, and the threaded rod 8 is matched with the threaded hole 9, so that the extrusion disc 2 is close to the positioning base 1; when the part 3 needs to be unloaded, the hexagonal boss 7 is rotated reversely.
Optionally, a connecting column 10 for connecting with a lathe is arranged at the rear end of the positioning base 1 along the axial direction; in particular, the connecting column 10 may be a cylinder.
When the fixture is used for fixing thin-wall lining plate parts, the connecting column 10 at the rear end of the positioning base 1 is firstly installed in a three-jaw chuck on a lathe, and the three-jaw chuck is aligned, clamped and fixed. Then the part 3 is arranged on the clamping ring 4 of the positioning base 1, then the threaded rod 8 in the locking mechanism is screwed into the threaded hole 9 on the positioning base 1, and is clamped on the hexagonal boss 7 at the front end of the locking mechanism by a wrench and is continuously screwed until the part 3 is locked by the expanded clamping ring 4. After the part 3 is clamped and fixed, turning the end face of the part 3; and turning the two end faces to the thickness dimension and the form and position tolerance for multiple times by using the same clamping method.
The fixture solves the problems of clamping and clamping deformation of thin-wall lining disc type parts, and the thin-wall lining disc type parts can be parts such as circular discs and the like; the positioning device is accurate in positioning and simple in structure, and can be used for processing lining disc type parts with the minimum wall thickness of 1.5 mm; meanwhile, the fixture effectively improves the production efficiency, ensures the product quality and meets the requirement of mass production.
