Abstract
A hold-down mechanism for quick assembly and disassembly consists of a nut with shoulders, an open washer, a round press plate, a draw bar, a base, a pin and a bolt. The draw bar is mounted on the base, a thread is arranged at one end of the draw bar, and the round press plate, the open washer and the nut with shoulders are placed on the draw bar. Four bolt holes are arranged on the base, the base is connected with a tooling base via the four bolt holes, the holes on the base are connected with the draw bar, and the draw bar is fixed on the base via the pin on the draw bar. The pin is mounted on the draw bar, and the draw bar is in interference fit with the pin. Two symmetrical U-shaped grooves are arranged on the base, and the draw bar can rotate on the base at a certain angle. During usage of the hold-down mechanism, the purpose of quickly assembling and disassembling workpieces can be realized only by rotating the draw bar and tightly screwing the nut with shoulders, and the hold-down mechanism is simple and convenient. Besides, the hold-down mechanism is fine in safety and stability, simple in structure, convenient and labor-saving in operation and high in reliability.
Description
Technical field
The utility model relates to mechanical, relates in particular to a kind of hold-down mechanism of quick workpiece loading and unloading.
Background technology
In actual production, often running into workpiece need compress, some workpiece, better compress in surface ratio, run into complicated workpiece, need compress in the workpiece the inside sometimes, and the endoporus by workpiece, this has just poorly pressed, need on the frock base, take root, for required precision than higher workpiece, common processing method, efficient is lower, can't reach desired required precision again.
Summary of the invention
The purpose of this utility model just provides a kind of hold-down mechanism of quick loading and unloading, can realize compressing and unclamping workpiece fast in the processing work process, and is easy to loading and unloading quick.
The technical solution of the utility model is as follows: the hold-down mechanism of loading and unloading is made up of band shoulder nut, open washer, round clamp, pull bar, base, pin, bolt fast.Pull bar 4 is installed on the base 5, and the TOE of pull bar 4 is put round clamp 3, open washer 2 and band shoulder nut 1 above.4 bolts hole are arranged on the base 5, by 4 bolts hole base 5 and frock base are linked together, hole on the base 5 and pull bar 4 link, and by the pin on the pull bar 46 pull bar 4 are fixed on the base 5.Pin 6 is contained on the pull bar 4, is interference fit between pull bar 4 and the pin 6.The U-lag that two symmetries are arranged on the base 5, pull bar can rotating certain angle on base.In use, only need rotating tension bar 4 and tighten the purpose that band shoulder nut 1 can be finished quick workpiece loading and unloading, convenient simply again.
Advantage of the present utility model: owing to adopt mechanical realization cleverly, simple in structure, cooperation requires low, easy to process, with low cost, and security and stability is good, rapid operation.
Description of drawings
Fig. 1 is the utility model section of structure.
Fig. 2 base front view
Fig. 3 base W-W profile
Fig. 4 is the work schematic diagram of the hold-down mechanism of loading and unloading fast
Among the figure: band shoulder nut 1, open washer 2, round clamp 3, pull bar 4, base 5, pin 6, bolt 7.
The specific embodiment
The hold-down mechanism of the quick loading and unloading that the utility model provides is made up of band shoulder nut 1, open washer 2, round clamp 3, pull bar 4, base 5, pin 6, bolt 7, below in conjunction with accompanying drawing technical scheme of the present invention is further described.
As shown in Figure 1, for interference fit is fixed together, the TOE of pull bar 4 is so that be connected with nut between pin 6 and the pull bar 4.When treating that work piece is placed on the frock, rotating tension bar 4 is fixed on the base 5 pull bar 4 to certain angle, after the workpiece centering is intact, loads onto round clamp 3 construction opening packing ring 2 more earlier, tightens band shoulder nut 1 at last, and workpiece is fixed on the frock.At this moment just can process.After processing, unclamp band shoulder nut 1, take down open washer 2 and round clamp 3, pull bar 4 can Panasonic by rotation, and also at this moment Panasonic not just can unload work piece.Because fast assembling and disassembling device needs frequent dismounting, as base 5, pin 6, pull bar 4, round clamp 3, need heat-treat modified, to improve their wearability.As Fig. 4 is casing process schematic diagram, there are two places to utilize this principle that workpiece is compressed, workpiece is placed on two step surfaces of frock, the pull bar 4 of fast assembling and disassembling device puts in the inside of workpiece by the circular hole of workpiece, refill round clamp 3 above the pull bar 4, open washer 2, band shoulder nut 1, base 5 is in the same place with Bolt Connection with the frock base, tighten (unclamping) band shoulder nut 1, can realize loading and unloading fast, whole cargo handling process only needs all to finish several seconds, the operator is the too big strength of expense not also, save time and laborsaving, improved operating efficiency greatly.
Claims (1)
1. the quick hold-down mechanism that loads and unloads, form by band shoulder nut, open washer, round clamp, pull bar, base, pin, bolt, it is characterized in that: pull bar is installed on the base, the TOE of pull bar, put round clamp, open washer and band shoulder nut above, pin is contained on the pull bar, is interference fit between pull bar and the pin, the U-lag that two symmetries are arranged on the base, pull bar can rotating certain angle on base.
