Abstract
The utility model discloses a core assembly clamp for a water jacket base core of an automobile engine cylinder block. The core assembly clamp comprises a base, movable plate base core guide seats and water jacket core guide seats, wherein the movable plate base core guide seats and the water jacket core guide seats are located below the base; a movable plate is provided with a supporting column which extends upwards and penetrates through the base; water jacket cores are positioned by the water jacket core guide seats; base cores are supported and positioned through the base core double-grade guide seats simultaneously to obtain the relatively good positioning precision; the dead weights of the water jacket cores and the base cores are used for automatically centering and other forces are not applied to the water jacket cores and the base cores, so that the water jacket cores and the base cores can be protected; the risks of damaging the water jacket cores and the base cores in the positioning process are reduced and the point measurement errors of a transportation mechanical arm can be balanced.
Description
Technical field
The utility model relates to casting field, the cores assembling jig using in especially a kind of automobile engine cylinder-body casting manipulations.
Background technology
Automobile engine cylinder-body is typical complex thin-wall ironcasting.Cylinder body is produced in the water jacket basis core in the loam core adopting, the restriction of water-jacket core structure and cold core process, and its jacket core angle core assembly easy fracture, can only adopt manual method of playing glue to connect, and production efficiency and the fluctuation of loam core relative size are larger.In order to reach, playing glue connects basic core and jacket core automatically, need special-purpose cores assembling jig, but on existing fixture, basis core and the location of jacket core on fixture are extensive style, robot is transported to basic core and jacket core after fixture, basis core and jacket core can accurately not navigate on fixture, also have the risk of damaging.
Therefore, need a kind of new technical scheme to address the above problem.
Utility model content
The purpose of this utility model is the deficiency existing for prior art, and a kind of cores assembling jig for automobile engine cylinder-body water jacket basis core is provided, and damages the risk of basic core and jacket core when can conveniently locate and can reduce location.
For realizing above-mentioned utility model object, the utility model can adopt following technical scheme for the cores assembling jig of automobile engine cylinder-body water jacket basis core:
A kind of cores assembling jig for automobile engine cylinder-body water jacket basis core, comprise base, be positioned at the portable plate under base, the some guiders that are installed on base and set in a row, described each guider comprises a pair of corresponding basic core guide holder arranging and a pair of corresponding jacket core guide holder arranging, described jacket core guide holder is arranged between two basic core guide holders, described portable plate is provided with the support column that extends upward and run through base, and the medial surface of described basic core twin-stage guide holder is concaved with the accepting groove of accommodating support column; Described portable plate is also provided with the guide posts that runs through base.
Compare with background technology; the utility model is for the cores assembling jig of automobile engine cylinder-body water jacket basis core; jacket core is located by jacket core rod guide supports; and basic core is located by basic core rod guide supports simultaneously; can access good positioning precision; utilize the deadweight self-centering of jacket core and basic core; and apply other power to jacket core and basic core; can protect jacket core and basic core; reduce the risk of damaging in position fixing process, and can offset the error in point measurement of conveying robot.
Accompanying drawing explanation
Fig. 1 is the utility model for the stereogram of the cores assembling jig of automobile engine cylinder-body water jacket basis core, and has shown the state while placing jacket core and basic core.
Fig. 2 is the utility model for the cutaway view of the cores assembling jig of automobile engine cylinder-body water jacket basis core, and has shown state when jacket core and basic core are positioned on this fixture.
Fig. 3 is the utility model for the cutaway view of the cores assembling jig of automobile engine cylinder-body water jacket basis core, and has shown state when support column upwards ejects basic core.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
Refer to shown in Fig. 1 to Fig. 3, the utility model discloses a kind of cores assembling jig for automobile engine cylinder-body water jacket basis core, comprises base 1, is positioned at the portable plate 2 under base 1, the some guiders 3 that are installed on base 1 and set in a row.Described each guider 3 comprises a pair of corresponding basic core guide holder 4 arranging and a pair of corresponding jacket core guide holder 5 arranging, and described jacket core guide holder 5 is arranged between two basic core guide holders 4.Basis core twin-stage guide holder 4 is in order to guide and to carry the basic core 8 in location to fixture; Jacket core guide holder 5 is in order to guide and to carry location jacket core 9 to fixture.Described portable plate 2 is provided with the support column 21 that extends upward and run through base 1.The medial surface of described basic core guide holder 4 is concaved with the accepting groove (not label) of accommodating support column 21, support column 1 can be done upper and lower movement in accepting groove, when basic core 8 need to be when basic core guide holder 4 departs from, portable plate 2 is moved up and makes support column 21 upwards eject basic core 8, and because support column 21 is to be close to basic core guide holder 4 and to make support column 21 upper surface portion be positioned at basic core guide holder 4 medial surface scopes owing to being arranged in accepting groove, therefore the lower surface that can better contact basic core when ejecting is to keep stability.Described portable plate 2 is also provided with the guide posts 22 that runs through base 1, this guide posts 22 can not interfered with basic core twin-stage guide holder 4 and basic core 8 when arranging, when portable plate 2 and base 1 mutually near or away from time, along guide posts 22, move, 22 guidings of guide posts and positioning action, and share the cross force being subject on support column 21.The part of the upper surface of described basic core guide holder 4 is zigzag 42, prevents that floating sand from affecting positioning height, guarantees that the assembling of basic core 8 highly meets the requirements.Both ends of the surface and the lateral surface of basis core twin-stage guide holder 4 extend upward respectively guide pad 43, and each guide pad 43 is equipped with the guide surface of inclination.The lateral border of described jacket core guide holder 5 is provided with upwardly extending locating piece 51, and described locating piece 51 is arc.When water jacket basis core is positioned on this fixture, the jacket core 9 comprising in the core of water jacket basis is by jacket core guide holder 5 supporting and locations, and basic core 8 is simultaneously by basic core guide holder 4 supporting and locations, utilize the deadweight self-centering of jacket core 9 and basic core 8, can offset the error in point measurement of conveying robot.On described base, be also provided with a pair of auxiliary support plate 6, described auxiliary support plate 6 between two jacket core guide holders 5 in order to supplemental support jacket core 9.
