Description
Technical Field
The utility model relates to a processing anchor clamps technical field specifically is an anchor clamps of thin wall dysmorphism casing.
Background
A special-shaped shell part is machined into a certain section of conical surface, the outline degree of the hole center and the end surface is required to be 0.035, the assembly function belongs to a sealing surface, but the structure of the part section is far away from a datum factor, and the part section is of a part thin-wall structure, as shown in figure 1. A chuck, an expansion sleeve and the like are generally adopted in a conventional automatic tool, but a standard clamp cannot be adopted for clamping and turning due to the structural specificity and the processing technology specificity of parts, so that clamping deformation is easy to generate after the turned thin-wall parts are clamped.
Disclosure of Invention
In order to solve the unable tight part of clamp of current standard anchor clamps, warp easily, influence follow-up lathe work's problem, the utility model provides an anchor clamps of thin wall dysmorphism casing, its realization part that can be convenient presss from both sides tightly, can not warp, guarantees follow-up lathe work quality.
The technical scheme is as follows: the utility model provides an anchor clamps of thin wall dysmorphism casing, its characterized in that, it includes the anchor clamps main part, transition ring flange, the preceding ring flange of other end connection are connected to anchor clamps main part one end, preceding ring flange inboard is fixed with the locating piece of taking the locating pin, anchor clamps main part side has been seted up the part and has been got and put the mouth, install the uide bushing in the anchor clamps main part, slidable mounting has the hold-down spindle in the uide bushing, hold-down spindle one end is connected the pull rod nut, the other end is installed with part appearance complex pressure head.
The pressing head is further characterized by comprising a front pressing plate and a rear stop block, wherein the end part of the pressing shaft penetrates through the rear stop block and is provided with a spherical head, a spherical concave surface matched with the spherical head is formed in the front pressing plate, a counter bore is also formed in the front pressing plate, a spring for connecting the spherical head with the bottom surface of the counter bore is installed in the counter bore, an annular groove is formed in the peripheral surface of the pressing shaft, one end of the rear stop block is clamped in the annular groove, and the other end of the rear stop block is clamped with the front pressing plate;
the front flange plate is fixed on the clamp main body through an adjusting support and a bolt.
Adopt the utility model discloses afterwards, the part of thin wall special-shaped casing edgewise is got the mouth and is put into, cooperates the locating pin to realize the location on the locating piece is arranged in to the one side, then utilizes the pull rod nut who connects drive arrangement to drive the compressing shaft and remove, pushes down the another side and fixes the part, and convenient realization the part presss from both sides tightly, and the pressure head does not can make the part press deformation with the cooperation of part appearance, has guaranteed follow-up lathe work quality.

Detailed Description
See fig. 2, fig. 3, fig. 4 shows, a fixture for a thin-wall special-shaped shell, which includes a fixture main body 1, a transition flange 2 is connected to one end of the fixture main body 1, a front flange 3 is connected to the other end of the fixture main body, a positioning block 5 with a positioning pin 4 is fixed on the inner side of the front flange 3, a part taking and placing opening 6 is formed in the side surface of the fixture main body 1, a guide sleeve 7 is installed on the fixture main body 1, a pressing shaft 8 is installed in the guide sleeve 7 in a sliding manner, a pull rod nut 9 is connected to one end of the pressing shaft 8, a pressing head 10 matched with the appearance of the part is installed at the other end of the pressing shaft, the pull rod nut 9 is used for being connected with the power end of a machine tool, and power of the pressing shaft 8 is provided.
The pressure head 10 includes preceding clamp plate 11 and backstop 12, and 8 tip of hold-down shaft run through backstop 12 and be equipped with the sphere head, set up on the preceding clamp plate 11 with sphere head complex spherical concave surface, still seted up counter bore 13 on the preceding clamp plate 11, install the spring 14 of connecting sphere head and counter bore 13 bottom surface in the counter bore 13, the annular groove 15 has been seted up to the 8 outer peripheral faces of hold-down shaft, 12 one end of backstop clamps in annular groove 15, the other end and preceding clamp plate 11 joint. The spherical surface contact can increase the rotational freedom degree, and aims to correct the parallel error between the pressing surface of the front pressing plate 11 and the part pressing surface, ensure the overall contact, prevent local point contact and avoid turning deformation caused by uneven stress; in addition, a strong spring is arranged in the central area, so that the front pressing plate 11 is prevented from inclining due to self gravity, the front end surface of the front pressing plate 11 is not perpendicular to the axis of the main shaft, and uneven stress is caused to a product during pressing.
The front flange 3 is fixed on the clamp body 1 through the adjusting bracket 16 and the bolts 17, and other front flanges 3 can be replaced as required to meet the positioning of parts with different sizes and appearances. In the figure, 18 is a balancing weight.
The utility model discloses can carry out high efficiency processing to the sealed conical surface and the aperture of this thin wall dysmorphism casing part, compare traditional car chuck or manual jig, improve machining efficiency on the one hand, on the other hand has improved the part machining quality.
