Abstract

The invention relates to a positioning device for assembly and installation of a sand core, comprising a substrate, at least one knighthead arranged on the substrate, a sand core shore which is arranged on the substrate and used for placing the sand core, at least one detecting rod arranged on each knighthead, detecting tools which are arranged on one end of each detecting rod and used for positioning the sand core, wherein, a plurality of knightheads are arranged around the sand core shore. The positioning device for assembly and installation of the sand core can detect the position of individual sand core and the coordinating position of a plurality of sand cores of complex and numerous sand core sets with high precision requirement in the process of assembly and installation, thus ensuring precision of cast products produced by using core sets positioned by the positioning device of the invention.

Description

The positioner of core assembling

Technical field

The present invention relates to a kind of positioner, especially in the core assembling process, be used to locate and detect the positioner of each core.

Background technology

During casting, in order to form the foundry goods internal cavities, often be made into core sand by sand grains and binding agent (as clay, tung oil or resin etc.), craft or machine in core box (as blowing machine or penetrate sand machine etc.) are made core (or being called core).Core need pass through oven dry, and installs in casting mold before casting.Afterwards, molten metal is poured into wherein and, when shaking out, it is removed, can form cavity in the foundry goods through condensing steps.

When producing complicated foundry goods (first-class) in batch or in a large number, a plurality of cores can be assembled successively the core assembly of the final profile that becomes to have the moulding part that to produce as cylinder.In assembling process, need position and detect cooperate degree between the core to each core.

Summary of the invention

The object of the present invention is to provide a kind of positioner that in core is assembled into the process of core group, is used to locate and detect cooperate degree between the core.

For achieving the above object, the technical solution adopted in the present invention is:

A kind of positioner of core assembling, comprise substrate, be arranged on substrate at least one support bar, be arranged on the suprabasil core support column that is used to place core, be arranged at least one test rod on each support bar, be arranged on each test rod one end and be used to locate the testing tool of core, a plurality of support bars are provided with around the core support column.

Because the employing of technique scheme, the present invention has the following advantages:

The positioner of core assembling can realize to the high core group of complicated, most amounts, required precision in assembling process individual core position and the cooperation position of a plurality of cores detect, guaranteed to use the accuracy of the foundry goods of producing through the core group of the present invention location.

Wherein: 1, substrate; 2, support bar; 3, core support column; 4, test rod; 5, testing tool; 6, spanner; 7, core connector; 71, screw rod; 72, nut; 8, core.

The specific embodiment

Fig. 1 looks cutaway view for master of the present invention, and a left side of the present invention is looked, the right side is looked, the backsight cutaway view is with main to look cutaway view identical.

The positioner of core assembling as shown in Figure 1, comprise substrate 1, slidably be arranged in the substrate 1 and at least one support bar 2 that its bearing of trend is vertical with the plane at substrate 1 place, be arranged on being used in the substrate 1 place core 8 core support column 3, be arranged at least one test rod 4 on each support bar 2, be arranged on each test rod 4 one end and be used to locate the testing tool 5 of core, a plurality of support bars 2 are provided with around core support column 3.

The positioner of core assembling comprises that 2, four support bars 2 of four support bars lay respectively at left side, right side, the place ahead, the rear of a plurality of core support columns 3.

Test rod 4 slidably is arranged on the support bar 2, and the glide direction of test rod 4 is the bearing of trend of support bar 2.

Test rod 4 also has another glide direction angled with the bearing of trend of support bar 2.Another glide direction of test rod 4 is vertical with the bearing of trend of support bar 2.Be that test rod 4 can go deep into and extraction core 8 along the left and right directions among Fig. 1, also can move up and down, different core 8 is positioned detection along the bearing of trend of support bar 2.

Testing tool 5 is a wear plate, has characteristic face on the detected core 8, and testing tool 5 is by detecting described characteristic face location core 8.Here, characteristic face is chosen the plane.

Along on the bearing of trend of support bar 2, on the core support column 3 from bottom to top be provided with a plurality of cores 8, by core connector 7 a plurality of cores 8 are connected successively.It also comprises the spanner 6 that is arranged in the substrate 1 and is used for fastening core connector 7.In the present embodiment, core connector 7 comprises a nut 72 that passes the screw rod 71 of each core 8 and be arranged on screw rod 71 ends, has the passage that is used for by screw rod 71 on the core 8.

Use the present invention locatees core in the assembling process of core 8 process is as follows:

At first, nut 72 is placed on spanner 6 upper ends, to pull out test rod 4 and connection testing tool 5 thereon away from the direction of core support column 3;

Then, on core support column 3, place and place core 8 successively, core 8 of every placement, bearing of trend along support bar 2 moves test rod 4 to setting height, stretch out the characteristic face that is had with this core 8 testing tool 5 (wear plate) that matches to the direction of this core 8, measure the gap length of testing tool 5 and this characteristic face, adjusting this core 8 to the gap of measuring between testing tool 5 and this characteristic face meets the demands, this step is used to detect the size shape of single core 8, makes its assembling of satisfying core and casting requirement;

Then, treat all cores 8 all place finish after, 5 pairs of core groups of four testing tools that use is positioned at core group front, rear, left and right detect, this step is used to detect the cooperate degree between the core 8, as, when the contact-making surface between the adjacent core 8 was the inclined-plane, this step can detect the phenomenon whether the position skew is arranged between these two adjacent cores 8;

At last, screw rod 71 is inserted each cores 8, rotating spanner 6 makes the lower thread engagement of the nut 72 that is positioned at spanner 6 upper ends and screw rod 71, by, screw rod 71 and nut 72 are fastening with the core group.
