Abstract
The invention discloses a positioning device for automatically centering a pore of a casting. The device comprises an annular bracket, wherein the annular bracket is fixed on an intermediate body through a bolt; three T-shaped grooves are uniformly distributed on the annular bracket; a T-shaped slider is arranged in each of the T-shaped grooves; the arcs of the inner side surfaces of the three T-shaped sliders form an annular cavity; the outer diameter of the T-shaped slider is provided with an annular groove; an extension spring is assembled in the annular groove; a cylinder is arranged below the intermediate body; a piston rod of the cylinder is fixedly connected with a pull rod; the pull rod passes through and extends out of the intermediate body and the bracket; the extension end of the pull rod is sleeved with a compression spring; an expansion sleeve is mounted at the top end of the pull rod above the compression spring; and the expansion sleeve is just in arc surface contact with the inner side surface of the T-shaped slider in the annular cavity. The device disclosed by the invention can ensure the stability of the positional dimension, easily clamp the workpiece and effectively control the machining allowance, thereby improving the production efficiency and quality and reducing the production cost.
Description
Technical field
The present invention relates to be used in a kind of machining the device with the location, hole, mainly is a kind of in the foundry goods mistake
The casting pore automatic capturing center of circle positioner that uses in the journey.
Background technology
The processing belt hole casting parts will be located with the hole of casting, usually adopt cylinder alignment pin location blowhole, and the pore of casting is difficult to guarantee uniformity, be convenient to clamping again, therefore all there is the gap all the time between cylinder alignment pin and the casting pore, often cause the surplus in hole monolateral, pitch-row generation deviation, even cause part to scrap.Need a kind ofly can be used for enhancing productivity, quality, reduce production costs the positioner in the foundry goods pore automatic capturing center of circle.
Summary of the invention
Technical problem to be solved by this invention provides the positioner in a kind of foundry goods pore automatic capturing center of circle, it can guarantee the stability of position dimension, and easily clamping workpiece is located reliable auto lock, effective control allowance is enhanced productivity, quality, is reduced production costs.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The positioner in a kind of foundry goods pore automatic capturing center of circle, include ring support, described ring support is by being bolted on the intermediate, evenly distribute on the described ring support and have three T-slots, be respectively equipped with T shape slide block with matching in described three T-slots, the arc of three T shape slide block medial surfaces is around constituting an annular chamber, and the external diameter of described T shape slide block has cannelure, is equipped with extension spring in the cannelure; There is cylinder described intermediate below, be fixedly connected with a pull bar on the piston rod of cylinder, described pull bar passes intermediate and support stretches out, be with a compression spring on the external part of described pull bar, the top that the pull bar top is positioned at the compression spring is equipped with expansion set, and described expansion set just in time contacts with the cambered surface of T shape slide block medial surface in annular chamber.
Have foundry goods to be placed on the support by pad, the pull bar top is stretched in the through hole of foundry goods.
Described expansion set is to be installed on the pull bar by nut and spacers.
The present invention can design the different slide block of external diameter according to pore size, to adapt to all kinds of machinings.
Slide block relies on oil cylinder to haul expansion set to expand among the present invention, make three points of slide block withstand blowhole, oil cylinder pins blowhole to power all the time, quality of fit is H7/g6 between support and pull bar, expansion set and the pull bar, slide block is constant all the time round the center of circle of support and pull bar always in the process that swells and dwindle, thereby realizes the function in the automatic capturing center of circle; When oil cylinder loosened, expansion set was compressed spring and ejects, and the slide block spring that is stretched shrinks, and has so just finished automatic location process.
Advantage of the present invention is:
The present invention can guarantee the stability of position dimension, and easily clamping workpiece is located reliable auto lock, effectively controls allowance, enhances productivity, quality, reduces production costs.
Description of drawings
Fig. 1 is a cutaway view of the present invention.
Fig. 2 is a vertical view of the present invention.
The specific embodiment
Referring to Fig. 1, the positioner in a kind of foundry goods pore automatic capturing center of circle, include ring support 3, described ring support 3 is fixed on the intermediate 2 by bolt 4, evenly distributing on the described ring support 3 has three T-slots, and the arc that is respectively equipped with 6, three T shapes of T shape slide block with matching slide block, 6 medial surfaces in described three T-slots is around constituting an annular chamber, the external diameter of described T shape slide block 6 has cannelure, is equipped with extension spring 11 in the cannelure; There is cylinder 1 described intermediate 2 belows, be fixedly connected with a pull bar 5 on the piston rod of cylinder 1, described pull bar 5 passes intermediate 2 and support 3 stretches out, be with a compression spring 12 on the external part of described pull bar 5, the top that pull bar 5 tops are positioned at the compression spring is equipped with expansion set 7, and described expansion set 7 just in time contacts with the cambered surface of T shape slide block 6 medial surfaces in annular chamber.
Have foundry goods 13 to be placed on the support 3 by pad 10, pull bar 5 tops are stretched in the through hole of foundry goods 13.Described expansion set 7 is to be fixedly mounted on the pull bar 5 by nut 9 and pad 8.
When oil cylinder 1 piston rod pulled down, pull bar 5 had been with expansion set 7 to descending, and compression spring 12 is stressed thereupon, and expansion set 7 promotes slide block 6 and moves to diametric(al), and stretching extension spring 11 is stressed subsequently, and workpiece 13 endoporus are pinned by three some diebacks on the slide block 6; When oil cylinder 1 upwards loosened, compression spring 12 headed on expansion set 7 and withdraws from pull bar 5, made slide block 6 withdrawal original positions with rear slider 6 under the active force of stretching extension spring 11.
Claims (3)
