A kind of die casting base of fixture
Technical field
This utility model relates to the clamp art of machining, the die casting base of a kind of fixture.
Background technology
At present, all there is structure complexity greatly in the fixture employed in enterprise's processing activity, one-piece parts is many, quality is big and inconvenience problem is installed in manually moving of causing.Wherein, clamp structure its cost of manufacture complicated is inevitable the highest;During the Each part of fixture is constituted, such as in the structure composition of clamp body (base) this part, being to be formed by connecting by multiple Component compositions, multiple components are connected fixing by substantial amounts of bolt in the past.Therefore, the fixture of this kind of version is unfavorable for saving material in manufacturing process, energy consumption is big and manufacturing man-hours is longer.
To sum up, how to produce high-quality part, to saving material, the energy and shortening manufacturing man-hours, increase economic efficiency and all make great sense.
Utility model content
The purpose of this utility model is, for above-mentioned deficiency, it is provided that one is simple for structure, reasonable, be used for simplifying clamp structure, saves the die casting base of the fixture of cost of manufacture.
For achieving the above object, technical scheme provided by the utility model is: the die casting base of a kind of fixture, including the base plate being made into integration by alloy die cast, gripper shoe and datum plate, the quantity of described gripper shoe is two pieces, two gripper shoes are symmetrically formed on a plate face of described base plate, described datum plate is paralleled with base plate across the top in two gripper shoes, the medium position of the dual-side that described datum plate is symmetrical be equipped with one outside corresponding side horizontal expansion raised, the medium position of datum plate end face is provided with multiple structure hole.
Another preferred version of the present utility model, the outer contour shape of described base plate is rectangle, the outer contour shape of described two gripper shoes is rectangle, two gripper shoes are perpendicular to the plate face of base plate and are parallel to each other, and dual-side that the length of two gripper shoes the is longer dual-side shorter with the length of base plate is parallel to each other and length dimension is equal.
Another preferred version of the present utility model, described datum plate is positioned at the top position, middle part in the plate face of described base plate.
The beneficial effects of the utility model are: compared with conventional art, and this utility model has simplified clamp structure, overall light weight and also structural strength is good;When die casting base is carried out subsequent structural hole and Surface Machining, process greatly simplified, required manufacturing procedure is few, processing time length, thus the die casting base finished product produced is easier to obtain excellent surface quality and overall dimensional accuracy.Due to generally integrated die-casting molding, whole possessing cost is low.
Below in conjunction with the accompanying drawings with embodiment, this utility model is further illustrated.
Accompanying drawing explanation
Accompanying drawing is used to offer and is further appreciated by of the present utility model, and constitutes a part for description, is used for explaining this utility model, is not intended that restriction of the present utility model, in the accompanying drawings together with detailed description below.
Fig. 1 is the understructure schematic diagram of conventional art fixture.
Fig. 2 is structural representation of the present utility model.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is illustrated.It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains this utility model, it is not limited to this utility model.
This utility model is the understructure of fixture, generally integrated die-casting molding.Figure of description 1 is the understructure of conventional art fixture, including base plate 100, base gripper shoe 200, base datum plate 300 and the limited block 400 being connected to base datum plate 300 both sides, this base plate 100, base gripper shoe 200 and base datum plate 300 are single component, all offer the fixing hole for being connected to a fixed, substantial amounts of bolt is used to connect when assembling fixing, structure is complicated, and processing cost is high.
See Fig. 2 and Fig. 3, the die casting base of a kind of fixture that the present embodiment provides, including the base plate 1 being made into integration by alloy die cast, gripper shoe 2 and datum plate 3, the quantity of described gripper shoe 2 is two pieces, two gripper shoes 2 are symmetrically formed on a plate face of described base plate 1, described datum plate 3 is paralleled with base plate 1 across the top in two gripper shoes 2, the medium position of the dual-side of described datum plate 3 symmetry is equipped with one outside corresponding side raised the 32 of horizontal expansion, and the medium position of datum plate 3 end face is provided with multiple structure hole 31.
Preferably, above-mentioned alloy is aluminium alloy;This utility model generally integrated die-casting molding, compares conventional art, has simplified structure, light weight and also structural strength is good;When die casting base is carried out structure hole 31 and Surface Machining, required manufacturing procedure is few, processing time length, thus the die casting base finished product produced is easier to obtain excellent surface quality and overall dimensional accuracy.
In the present embodiment, described projection 32 is die casting base when assembling with the clamping device of fixture or setting element for the movable spacing position limiting structure of component, substitutes described limited block 400 for correspondence, sees Fig. 1 and Fig. 2.The structural member recombinant that the use that relatively conventional art uses individually processes is to the version of base, and the dimensional accuracy of the structure of described projection 32 is good, and whole possessing cost is low.
The outer contour shape of the base plate 1 of the present embodiment is rectangle, the outer contour shape of described two gripper shoes 2 is rectangle, two gripper shoes 2 are perpendicular to the plate face of base plate 1 and are parallel to each other, and dual-side that the length of two gripper shoes 2 the is longer dual-side shorter with the length of base plate 1 is parallel to each other and length dimension is equal.The datum plate 3 of the present embodiment is positioned at the top position, middle part in the plate face of described base plate 1.The length dimension of two gripper shoes 2 is equal with the width dimensions of base plate 1, sees Fig. 3, and two gripper shoes 2 form a boss with datum plate 3 on the plate face of base plate 1, and this boss assembles for clamping device or the setting element adaptation with fixture.
Compared with conventional art, this utility model has simplified clamp structure, overall light weight and also structural strength is good;When die casting base is carried out subsequent structural hole 31 and Surface Machining, process greatly simplified, required manufacturing procedure is few, processing time length, thus the die casting base finished product produced is easier to obtain excellent surface quality and overall dimensional accuracy.Due to generally integrated die-casting molding, whole possessing cost is low.
Although embodiment of the present utility model is disclosed as above, but it is not restricted in description and embodiment listed application, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, it is easily achieved other amendment, therefore, under the general concept limited without departing substantially from claim and equivalency range, this utility model does not limit specific details and shown here as the legend with description.
