Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1-4, an adjustable mold frame clamping mechanism of a block forming machine is provided, and the block forming machine is provided with a frame 8. The clamping mechanism comprises a clamping base 1, a first lifting rod 2, an adjusting sleeve 3, a second lifting rod 4, a fulcrum seat 12, a clamping lever plate 5, an air spring 6 and a clamping block 7. The utility model discloses a pneumatic clamping device, including centre gripping base 1, centre gripping lever plate 5, air spring 6, clamping block 7, fulcrum seat 12 is fixed on centre gripping base 1, rotatable the setting up of centre gripping lever plate 5 is on fulcrum seat 12, centre gripping lever plate 5 uses the turning point to divide into initiative board 51 and passive board 52 as the boundary, the tip of initiative board 51 and the one end fixed connection of air spring 6, clamping block 7 fixed connection is at the tip of passive board 52, supply mould frame border 91 to insert between clamping block 7 and the centre gripping base 1. The specific principle is that the air spring 6 drives the driving plate part 51 to tilt up, so that the driven plate part 52 droops, the clamping block 7 is driven to droop to be matched with the clamping base 1 to clamp the edge 91 of the mold frame, and therefore the clamping height of the clamping mechanism can be changed by changing the height of the clamping base 1.

The lower end of the second lifting rod 4 is connected with the clamping base 1, the first lifting rod 2 and the second lifting rod 4 are coaxially arranged, the adjusting sleeve 3 comprises adjusting parts which are respectively arranged at the upper end and the lower end, the adjusting part at the upper end is movably sleeved at the lower end of the first lifting rod 2, the adjusting part at the lower end is movably sleeved at the upper end of the second lifting rod 4, and the axis of the adjusting sleeve 3 coincides with the two lifting rods. First lifter 2 is connected with frame 8 to frame 8 realizes going up and down as the strong point, has the spacing between first lifter 2 and the second lifter 4, and the spacing change can the height of centre gripping base 1.

Like this, because second lifter 4 is connected with centre gripping base 1, consequently first lifter 2 goes up and down and can drive second lifter 4 and centre gripping base 1 and go up and down simultaneously to can drive the mould frame 9 and go up and down when centre gripping mould frame 9. When replacing the mold frames 9 with different specifications, the two adjusting parts loosen the first lifting rod 2 and the second lifting rod 4, and reduce or increase the adjusting distance between the two, so that the height position of the clamping base 1 is changed, and the mold frame edges 91 with different heights are clamped. The scheme flexibly adapts to clamping the mold frames 9 with different specifications while not influencing the normal lifting of the mold frames 9 in the brick making process.

As a specific example of the adjusting portion, the adjusting portion is provided with a locking screw 32 and two tightening portions 31, the two tightening portions 31 are semi-annular in cross section and have a space between the two tightening portions 31 for slight deformation, and the locking screw 32 penetrates the two tightening portions 31 to fasten the two tightening portions 31. When needing to adjust, loosen locking screw 32, make two elasticity portions 31 loosen, make elasticity portion 31 and two lifter gappedly, be convenient for remove the lifter, after adjusting, two elasticity portions 31 are locked to rethread locking screw 32, make two elasticity portions 31 hold the lifter tightly, realize fixedly.

For more convenient regulation, preferably, two regulation portions have the regulation screw thread that rotation direction is opposite, first lifter 2 and second lifter 4 and regulation screw thread connection, like this, loosen locking screw 32 back, first lifter 2 and second lifter 4 keep threaded connection with the regulation portion, make centre gripping base 1 can not drop because of losing the pulling force totally and accident, and the structure is more stable. And just can realize the interval adjustment of two lifter through corotation or reversal regulating part, it is very convenient to adjust.

The clamping base 1 is further provided with two fixing plates 11, and the lower end of the second lifting rod 4 is locked between the two fixing plates 11, so that the second lifting rod 4 is connected with the clamping base 1.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
