Abstract

The utility model discloses a composite fixture, which comprises a first fixture body, a second fixture body and a third fixture body. The first fixture body is of a step shaft shape. Male threads are arranged at the external part of the step with large shaft diameter. The part with small shaft diameter is installed on the chuck of a lathe. The second fixture body is of a ring shape. Female threads matched with the male threads of the first fixture body are arranged in a ring inner hole. The third fixture body can be fixed on the first fixture body through screws. The third fixture body is equivalent to a through gauge and can support the inner hole of a workpiece to be machined. By adopting the technical scheme, the utility model has the advantages that the structure of the composite fixture is unique and the machining of the outer diameter and the inner diameter can be completed in one step of clamping; the fixture and the detecting (measuring) tool are ingeniously integrated into a whole body; and the trivial detection work is greatly reduced, and the probability of error judgment and wrong judgment caused by human factors is suppressed.

Description

A kind of compound anchor clamps
Technical field
The utility model relates to a kind of anchor clamps, refers in particular to a kind of compound anchor clamps at thin-walled parts, belongs to the metal cutting tool technical field.
Background technology
Characteristic according to the structural principle and the product form processing of common apparatus (lathe), the mode of the clamping (part) that equipment self is intrinsic, be generally chuck mode, that is: several methods such as three-jaw or four paws, interior pawl or outer pawl, hard pawl or soft pawl come clamping, fastening product parts.
At nonmetallic materials (material is: PE, POM, FR......) or metal material, when but product is the thin-wall construction part processing, because above-mentioned material inherent characteristic, the resistance to compression index a little less than, in case be subjected under the bloated influence of external force extruding/support, the part material internal stress, irregular variation takes place in moment, usually in clamping process, inevitably all metamorphosis can take place; And the part after the processing in case discharge through material stress " resilience ", causes product technology requirement, accessory size and actual processing dimension far from each other.The lighter is bad, and dimension overproof, precision reduce, the effect demultiplication; Weight person reprocesses, and qualification rate is low, seriously be to cause to scrap in batches; Work piece shown in accompanying drawing 1, accompanying drawing 2, material are PE.
Based on above-mentioned all multifactor phenomenons that causes, how, higher relatively to the part processing specification requirement at tradition (lathe) equipment, the product that geometry is special relatively, especially on the mode of clamping and link such as product processing method improve and perfect.My technical staff of company is by unique jig Design thinking, novel anchor clamps structure, the processing method of science, turns to integrated, new processing method/manufacturing process with polynary.
The utility model content
At the technical problem of above-mentioned existence, the purpose of this utility model is: proposed a kind of compound anchor clamps at thin-walled parts.
Technical solution of the present utility model is achieved in that a kind of compound anchor clamps, comprises first clamp body, second clamp body, the 3rd clamp body; Described first clamp body is a step axle shape, and the step outer setting that the diameter of axle is big has external screw thread, and the part that the diameter of axle is little is used for being installed on the chuck of lathe; Described second clamp body is circular, is provided with the internal thread that cooperates with the first clamp body external screw thread in the described circular endoporus; Described the 3rd clamp body can be fixed on first clamp body by screw, and the 3rd clamp body is equivalent to a drift, can support the endoporus of work piece simultaneously.
Preferably, also be provided with reference column on described the 3rd anchor clamps.
Preferably, described first clamp body is provided with the locating hole that cooperates with reference column, has the hole on the described first clamp body external diameter, and described hole is communicated with locating hole, is used for ventilating, to be convenient to extract reference column.
Preferably, have venthole on described second clamp body, when convenient the 3rd clamp body is packed into, the discharge of internal gas.
The compound anchor clamps of the utility model scheme have the following advantages: 1, by the cooperating of anchor clamps I and chuck, can convert traditional clamping the installation way of Z to (face contact) to by stressed source X to (point contacts), make the stressed source of its workpiece uniform, comprehensive; Because the displacement of the direction in the stressed source of workpiece, negatively influencing power is almost nil; Thereby stopped the workpiece material owing to be subjected to the influence of external force effect to cause the outward appearance deformation of part; In actual process, guaranteed technical characteristic and every index request of product; 2, adopt combined type anchor clamps II, III to intersect supporting use, changed conventional gimmick, the general inside and outside Surface Machining of workpiece, the traditional handicraft of clamping respectively; Make original product multi-step process, concentrate in procedure and process in the lump.Not only avoided having improved efficient because multiple clamping and accumulated error that equipment precision caused have also been saved the time simultaneously in a large number.Particularly outstanding is: owing to adopt the technology of (1), (2), can make original processing parts degree-of-difficulty factor be reduced to minimum.For the processing of thin-walled parts, advantage more obvious (by practice: the part wall thickness only can be controlled for>0.80mm); 3, unique compound anchor clamps are constructed, the scientific utilization space technology, and with two kinds of distinct materials, that is: anchor clamps and inspection (amount) tool combines together cleverly; The directed combination of employing, tight edge are joined, slitless connection; Not only make part in process, every technical parameter is protected, the uniformity, stability of product (its precision can control≤0.004mm within) are fully controlled simultaneously; And reduced or remitted the loaded down with trivial details work of testing in a large number, and suppressed because the erroneous judgement that human factor caused, the probability of misjudgement.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is the front view of part to be processed of the present utility model;
Fig. 2 is the stereogram of part to be processed of the present utility model;
Fig. 3 is the three-dimensional exploded view of a kind of compound anchor clamps of the present utility model.
The specific embodiment
Shown in accompanying drawing 1,2, work piece of the present utility model.
As shown in Figure 3, a kind of compound anchor clamps described in the utility model comprise first clamp body 1, second clamp body 2, the 3rd clamp body 3; Described first clamp body 1 is a step axle shape, and the step outer setting that the diameter of axle is big has external screw thread, and the part that the diameter of axle is little is used for being installed on the chuck of lathe; Described second clamp body 2 is circular, is provided with the internal thread that cooperates with the first clamp body external screw thread in the described circular endoporus; Described the 3rd clamp body 3 can be fixed on first clamp body 1 by screw 4, and the 3rd clamp body 3 is equivalent to a drift, can support the endoporus of work piece simultaneously; Also be provided with reference column 5 on described the 3rd anchor clamps 3; Described first clamp body 1 is provided with the locating hole 6 that cooperates with reference column, has hole 7 on the described first clamp body external diameter, and described hole is communicated with locating hole, is used for ventilating, to be convenient to extract reference column; Have venthole 8 on described second clamp body 2, when convenient the 3rd clamp body is packed into, the discharge of internal gas.
