Abstract
The utility model relates to a rigid clutch of a pressing machine, which belongs to technology field of the pressing machine; the utility model is the improvement of the existing rigid clutch structure of the pressing machine, and the characteristics of the utility model are as follows: the rigid clutch of the pressing machine mainly aims at the shortcoming that the existing clutch structure easily has 'rebound phenomenon', and a main key and a secondary key are respectively arranged at two grooves of an inner sleeve, in this way, the easily generated collision and interference caused by that the existing main key and the existing secondary key are located in one groove can be avoided, meanwhile, the main key and the secondary key are connected to form a 4-rods linkage mechanism, that is, the connecting ends of the main key and the secondary key are respectively connected respective rocking bars, and the two rocking bars are connected by a connecting plate; through respectively calculating the rotating angles of the main key rocking bar and the secondary key rocking bar, the main key and the secondary key are simultaneously sleeved at the groove of a middle sleeve, in this way, the combination of the middle sleeve and the inner sleeve is more stable. Even the machine has 'rebound phenomenon', the damage to parts is not caused, therefore, the stability of the pressing machine is enhanced and the service life of the rigid clutch is increased; the utility model has simple structure and good practicability.
Description
Technical field
The utility model relates to a kind of forcing press positive clutch, is for the working stability of positive clutch and a kind of structure that increases the service life and design, and belongs to the press technologies field.
Background technology
The major key of existing forcing press positive clutch and paying in the groove of key with cover in placing, and by major key with pay the transmission of the toothed separately key lever of key between realizing.This structure has certain drawback, when major key during by extension spring pulling work, if major key do not go into smoothly the middle cover of groove in will being rotated hit back in the cover, major key handle and pay being connected tooth and can being subjected to reaction force and making the flank of tooth be easy to fracture on the key lever, thus cause the clutch inefficacy.Just we " rebound phenomena " usually said.
Summary of the invention
The purpose of this utility model provides a kind of forcing press positive clutch, solve the major key of existing forcing press positive clutch and pay key because of in the groove with cover in placing, the flank of tooth fracture that easily causes the major key handle and pay key lever, thereby the deficiency that causes clutch to lose efficacy, overcome above-mentioned what is called " rebound phenomena " by the utility model, help strengthening the stability of forcing press and the service life of improving positive clutch.
The purpose of this utility model is achieved through the following technical solutions, a kind of forcing press positive clutch, comprise the interior cover in middle cover, the middle cover, major key and pair key and extension spring, it is characterized in that interior cover is provided with two grooves, a major key and a pair key split in two grooves, major key is connected an end of rocking bar separately respectively with the link of paying key, connects through connecting plate between the other end of two rocking bars.
The major key that puts in described, pay key groove shape respectively with major key, to pay the key moving range corresponding.
The center line angle of two grooves of cover is 44 degree in described, and the centre distance of two grooves is 82mm.
Described rocking bar ovalize, two rocking bars overlap major key respectively near the hole of end and pay the link of key, and be stuck with shaft block ring.
The utility model is the improvement to existing forcing press positive clutch structure, main feature is the deficiency that occurs " rebound phenomena " at existing clutch configuration easily, major key and pair key are placed respectively in two grooves of interior cover, avoid existing major key like this and paid collision and the interference that key is easy to generate because of being positioned at a groove, again by a major key and a pair key are connected to form four lever linkage mechanisms, be that major key and the link of paying key are connected rocking bar separately respectively, link to each other with connecting plate between two rocking bars, by calculating the rotational angle of major key rocking bar and pair key rocking bar respectively, a major key and a pair key are gone in the middle grooving simultaneously, and the combination of cover and interior cover is more stable in making like this.Also can not cause part to occur damaging even " rebound phenomena " appears in lathe, strengthen the stability of forcing press and the service life of improving positive clutch like this, the utility model is simple in structure, has very strong practicality.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the sectional structure schematic diagram of the utility model under disengaged condition;
Fig. 3 is the sectional structure schematic diagram of the utility model under bonding state;
Among the figure, cover in 1, cover in 2,3 major keys, 4 pairs of keys, 5 grooves, 6 grooves, 7 rocking bars, 8 rocking bars, 9 connecting plates.
The specific embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the utility model is by middle cover 1, interior cover 2, and major key 3 is paid key 4, groove 5,6, rocking bar 7,8 and connecting plate 9 constitute; During being arranged on, overlaps in 1 by interior cover 2, in the interior cover 2 groove 5, groove 6 are set, major key, pay key groove 5,6 shape respectively with major key 3, to pay key 4 movings range corresponding, the center line angle of two grooves 5,6 of interior cover is 44 degree, the centre distance of two grooves 5,6 is 82mm, a major key 3 and a pair key 4 split in groove 5, groove 6, and major key 3 is connected rocking bar 7 separately, an end of rocking bar 8 respectively with the link of paying key 4, connect through connecting plate 9 between the other end of rocking bar 7, rocking bar 8.So just a major key 3 and a pair key 4 are coupled together, major key 3 other ends are overlapping key lever, driving major key 3 by the pulling key lever during lathe action rotates, because major key 3 is connected by connecting plate 9 with a pair key 4, drive again and pay key 4 rotations, the groove of cover forms rotating once in conjunction with bent axle of a clutch, and so forth in entering behind the groove of cover in rotating out.
