Abstract

A clamping mechanism belongs to the technical field of mechanical fixtures and aims to provide a clamping device for a movable hinge pin with an external hinge pin sleeve. By the aid of the clamping device, a workpiece is clamped and released conveniently, finally, labor intensity of workers is reduced, and work efficiency is improved. The technical scheme includes that the clamping mechanism comprises a positioning hinge pin, a U-shaped groove, the movable hinge pin, the hinge pin sleeve and a locking handle, the positioning hinge pin is fixed onto a side wall of the U-shaped groove, the movable hinge pin is mounted on a side wall, which is opposite to the positioning hinge pin, of the U-shaped groove via the hinge pin sleeve, a slotted hole is disposed on the hinge pin sleeve, a track of the slotted hole is a sine curve, a hole is arranged on the movable hinge pin, and the locking handle is inserted into the hole on the movable hinge pin after penetrating through the slotted hole, with the sine curve track, on the hinge pin sleeve. The workpiece is clamped and released conveniently by the aid of the movable hinge pin and the hinge pin sleeve via the locking handle, the hole and the slotted hole with the sine curve, labor intensity of the workers is reduced, and work efficiency is improved.

Description

A kind of clamp mechanism

Technical field

A kind of clamp mechanism belongs to the mechanical clamp technical field.

Background technology

In the prior art, when the workpiece clamping process, when workpiece with after the alignment pin end face of anchor clamps contacts; Generally be that manual work is done whole moving with the active pin shaft of anchor clamps; Reach clamping, unclamp operation to workpiece, this working method labor strength is big, inefficiency.

The utility model content

The utility model overcomes the deficiency of prior art, and technical problem to be solved is: a kind of clamping device of active pin shaft of external pin sleeve is provided, and convenience realizes the clamping of workpiece and unclamps, and finally reduces labor strength, increases work efficiency.

In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of clamp mechanism; Comprise alignment pin, U-lag, active pin shaft, pin sleeve and set lever; Alignment pin is fixed on the sidewall of U-lag, and active pin shaft is installed on the U-lag sidewall relative with alignment pin through pin sleeve, and having track on the described pin sleeve is sinusoidal slotted eye; Have the hole on the active pin shaft, it is in the hole of inserting behind the sinusoidal slotted eye on the active pin shaft that set lever passes track on the pin sleeve.

The beneficial effect that the utility model compared with prior art has: active pin shaft and pin sleeve be through set lever, hole and sine curve slotted eye, realized the clamping of workpiece easily and unclamp, and reduced labor strength, improved operating efficiency.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further detailed explanation.

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the plane outspread drawing of pin sleeve in the utility model.

1 is U-lag among the figure, and 2 is alignment pin, and 3 is active pin shaft, and 4 is pin sleeve, and 5 is set lever.

The specific embodiment

As shown in Figure 1; A kind of clamp mechanism of the utility model comprises alignment pin 2, U-lag 1, active pin shaft 3, pin sleeve 4 and set lever 5, and alignment pin 2 is fixed on the sidewall of U-lag 1; Active pin shaft 3 is installed on the relative sidewall of U-lag 1 and alignment pin 2 through pin sleeve 4; Having track on the described pin sleeve 4 is sinusoidal slotted eye, has the hole on the active pin shaft 3, and it is in the hole of inserting behind the sinusoidal slotted eye on the active pin shaft 3 that set lever 5 passes track on the pin sleeve 4.

The course of work of the utility model does; Earlier workpiece is positioned on the U-lag 1; One side of workpiece contacts with alignment pin 2 end faces; When needs carry out clamp operation to workpiece, set lever 5 is moved along the sine curve slotted eye on the pin sleeve 4 to the direction near U-lag 1, drive active pin shaft 3 also to moving near U-lag 1 direction; Make the distance between alignment pin 2 and the active pin shaft 3 reduce, realize clamp operation workpiece.

When needs carry out unclamp operation to workpiece; With set lever 5 to moving along the sine curve slotted eye on the pin sleeve 4 away from U-lag 1 direction; Drive active pin shaft 3 also to moving away from U-lag 1 direction; Make the distance between alignment pin 2 and the active pin shaft 3 increase, realize unclamp operation workpiece.

Claims

1. clamp mechanism; Comprise alignment pin (2), U-lag (1), active pin shaft (3), pin sleeve (4) and set lever (5); Alignment pin (2) is fixed on the sidewall of U-lag (1); Active pin shaft (3) is installed on U-lag (1) sidewall relative with alignment pin (2) through pin sleeve (4); It is characterized in that: having track on the described pin sleeve (4) is sinusoidal slotted eye, and active pin shaft has the hole on (3), and it is in the hole of inserting behind the sinusoidal slotted eye on the active pin shaft (3) that set lever (5) passes the last track of pin sleeve (4).
