Description

A two-position simultaneous pressing device

technical field

The utility model belongs to the technical field of mechanical design and relates to a two-position simultaneous pressing device.

Background technique

In the field of machine tool fixtures, the devices used for simultaneous clamping of workpieces are mostly double-sided flat clamping devices. This device consists of four parts: the left clamping device, the right clamping device, the linkage block and the base supported by the ball head. composition. For most types of workpieces, single pressing is adopted, and tooling needs to be repeatedly put in each time, which inevitably has high cost and long manufacturing cycle.

Utility model content

The technical problem to be solved by the utility model is: to provide a multi-purpose and convenient two-way simultaneous pressing device. Type workpieces achieve multi-purpose pressing.

The technical scheme of the utility model is: a two-position simultaneous pressing device, including a left and right side pressing device, an interlocking block 6 and a base 8 containing a ball head support 5, which is characterized in that: the left and right side pressing devices The lower end of the swing bolt A7 has threads; the left and right pressing devices also include a limit nut 9; the limit nut 9 matches the swing bolt A7; the base 8 has a guide hole for the swing bolt A7 10. The diameter of the guide hole 10 is smaller than the outer diameter of the limit nut 9; the relief hole 12 of the joint bolt B2 on the base 8 and the pressure plate 3 is a groove type; the pressure plate 3 and the joint bolt A7 are axially connected.

The beneficial effects of the utility model are: the two simultaneous pressing devices of the utility model can realize a multipurpose and convenient two-way simultaneous pressing device; tests have proved that using the two-way pressing device of the utility model can greatly improve work efficiency and reduce Tooling costs.

Description of drawings

Fig. 2 is a schematic diagram of the use state of two simultaneous pressing devices of the present invention;

Among them, 1-double nut, 2-swing bolt B, 3-pressure plate, 4-spring, 5-ball head support, 6-linkage block, 7-swing bolt A, 8-base, 9-limit nut , 10-guide hole, 11-nut, 12-let open hole.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.

Referring to Fig. 1 and Fig. 2, a simultaneous pressing device at two places includes a left and right side pressing device, an interlocking block 6 and a base 8 containing a ball head support 5, and the hinged bolt A7 in the left and right side pressing device The lower end has threads; the left and right pressing devices also include a limit nut 9; the limit nut 9 is matched with the swing bolt A7; the base 8 is provided with a guide hole 10 for the swing bolt A7, and the guide hole 10 The diameter is less than the outer diameter of limit nut 9; The relief hole 11 of the swing bolt B2 on the base 8 and the pressure plate 3 is a groove type; The pressure plate 3 and the swing bolt A7 are axially connected.

The specific operation is: loosen the double nuts 1 and 11, use the force of the spring 4 to open the pressure plate 3, put the workpiece on the base 8, and use the locking effect of the double nuts to first fix the left pressing device, the left The key to the dual action of the pressing device on the right side is that the block 6 can rotate around the ball support 5. Using its linkage, the swing bolt A7 keeps moving up and down in a straight line in the guide hole 10 on the base 8. Face inclination, swing bolt B2 and swing bolt A7 reach the corresponding position, tighten the limit nut 9 to determine the support height of the swing bolt A7, and then tighten the right nut 11, due to the effect of linkage, reach the left and The right pressing device presses the workpiece at the same time.
