The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail; set forth in the following description more details so that fully understand the utility model; but the utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can do similar popularization, deduction according to practical situations without prejudice to the utility model intension in the situation that, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.
It should be noted that Fig. 1 to Fig. 3 is all only as example, it is not to draw according to the condition of equal proportion, and should not using this as the protection domain of the utility model actual requirement is construed as limiting.
As shown in Figure 1, compact self-locking mechanism comprises cylinder 1, briquetting 5, cylinder connector 6, connecting rod 7, organizational carrier and stop protective block 4.Organizational carrier consists of two parts in embodiment as shown in the figure, i.e. installing plate 2 and T shape seat 3.In embodiment described later, be appreciated that organizational carrier can be any different shape or structural form, as long as can support member wherein.
Cylinder 1 is fixed on the bottom of installing plate 2, in its piston rod 11 perforation from installing plate 2, sees through, and the end of piston rod 11 is connected with cylinder connector 6.
Briquetting 5 is roughly T-shaped, in Fig. 1, for rotating counterclockwise the T shape of 90 degree, has first end 51, the second end 52 and the outstanding compressed part 53 of level.
Connecting rod 7 has shorter size, seems approximate horizontal layout in Fig. 1, Fig. 2, in fact omits low dip, and left end exceeds right-hand member.
Stop protective block 4 stands upright on installing plate 2, and its dorsal part 41 is vertical plane.Stop protective block 4 is L shaped.Explanation by below, is appreciated that, stop protective block 4 also can be one-body molded as a member with organizational carrier.
Continue to see figures.1.and.2, cylinder connector 4 is arranged on the piston rod 11 of cylinder 1, the first end 71 of the end articulated linkage 7 of cylinder connector 4, the first end (upper end) 51 of the hinged briquetting 5 of the second end 72 of connecting rod 7, second end (lower end) 52 of briquetting 5 is hinged on organizational carrier (T shape seat 3), stop protective block 4 is fixedly installed on organizational carrier (installing plate 2), compressed part 53 workpiece pressings 8 that protrude between the first end 51 of briquetting 5 and the second end 52, stop protective block 4 with the pass of cylinder connector 6 is: the reaction force of the workpiece pressing 8 that this compressed part 53 is subject to is delivered to cylinder connector 6 by connecting rod 7, cylinder connector 6 leans against on stop protective block 4, so that stop protective block 4 is supported cylinder connector 6, and then locking cylinder connector 6, even if the unstable or workpiece pressing welding stress of the source of the gas of cylinder excessive also there will not be, compresses insecure phenomenon like this.But, under normal circumstances, stop protective block 4 and cylinder connector 6 can be discontiguous, when compressing unreliable will appearance, and the two contact.Cylinder 1 can drive cylinder connector 6 to connect 6 with release cylinder, as shown in Figure 3, cylinder 1 drives cylinder connector 6 to move down, and due to the size relationship between cylinder 1, briquetting 5, cylinder connector 6, connecting rod 7, briquetting 5 can be overturn counterclockwise, and its maximum flip angle a is greater than 90 degree.
Stop protective block 4 is supported the side 41 of cylinder connector 6 and the first end of briquetting 5 51, the described hinged center 1B of the second end 52,1C line is parallel; and the described hinged center 1A of the end of cylinder connector 6 will exceed the described hinged center 1B of the first end 51 of briquetting 5; in the embodiment shown in Fig. 1 and Fig. 2; if the position of center 1A is lower or equal than the position of center 1B, the effect of self-locking is bad.
Further; be appreciated that; as long as mutually push or compress or support under the impaction state of stop protective block 4 and cylinder connector 6 Neng mechanisms; just can reach the effect of self-locking, so the profile variation of cylinder 1, briquetting 5, cylinder connector 6, connecting rod 7, organizational carrier and stop protective block 4 is a bit what it doesn't matter.
In preferred embodiment as shown in the figure; organizational carrier comprises the installing plate 2 of level and upright T-shaped seat 3; stop protective block 4 also stands upright on installing plate 2; cylinder 1 is vertically fixed on installing plate 2; but as long as mutually push or compress or support under the impaction state of stop protective block 4 and cylinder connector 6 Neng mechanisms, not upright being yet fine.
Stop protective block 4 is the L shaped cylinder connector 6 that leans against, and obviously stop protective block 4 is also fine for square column type, cylindrical or other shapes.
As shown in Figure 2, when briquetting 5 compressions put in place, the left side pan axis (hinged center) of connecting rod 7 exceeds 1mm slightly than right side pan axis (hinged center).Stop protective block 4 is key components of self-locking, and protection cylinder connector 6 can not be subjected to displacement when being subject to workpiece welding stress.As shown in the figure, by four connecting rods, realize self-locking, thereby greatly reduce the space of occupying of mechanism.And mechanism opening angle is very large.Pressure head open angle is greater than 90 ° (approximately 110 °).
The operation principle of this mechanism is:
Gas on cylinder 1, cylinder connector 6 is up, thus drivening rod 7 and briquetting 5 compress.When cylinder connector 6 is up while putting in place, briquetting 5 compresses completely, and has realized the self-locking that puts in place.
Cylinder 1 loses heart, and cylinder connector 6 is descending, thereby drivening rod 7 and briquetting 5 unclamp workpiece, and when cylinder connector 6 is descending while putting in place, briquetting 5 is opened completely and open angle is greater than 90 °, approximately 110 °; Realize mechanism and open completely and step down, facilitate the taking-up of workpiece and the clamping of next workpiece.
Aforesaid embodiment can be widely used in auto parts and components and produce in each techniques such as assembling, realizes workpiece is compressed reliably, and open angle is large, facilitates workpiece to take out.This mechanism design is compact simultaneously, and adaptability just can not be limited by the problems such as insufficient space; Also be the operating efficiency that improves station, and large quantity space has been reserved in swinging cross production.
Although the utility model with preferred embodiment openly as above, it is not for limiting the utility model, and any those skilled in the art, within not departing from spirit and scope of the present utility model, can make possible change and modification.Therefore, every content that does not depart from technical solutions of the utility model, any modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, within all falling into the protection domain that the utility model claim defines.
