The large-sized part lateral clamping fixture consists of a fixture body, a driving screw and a sliding chuck, the driving screw and the sliding chuck are arranged in the fixture body, the fixture body consists of a lower fixture body and an upper fixture body fixed on the same, the fixture body is provided with a passage penetrating through two ends of the clamp body, and the driving screw and the sliding chuck are disposed in the passage. The clamping fixture is simple in structure and convenient in operation, can laterally clamp large-sized parts on machine tools with extremely reliable clamping.

Description

Heavy parts side direction clamping device

Technical field

The utility model relates to the anchor clamps of part to be processed in the field of machining, particularly the heavy parts side direction is clamped in the heavy parts side direction clamping device on the platen face.

Background technology

During processing parts, part must be fixedly clamped reliably on the work top of lathe on lathe, generally speaking, being fixedly clamped of part is that clamping force by anchor clamps are bestowed vertical direction (promptly vertical with platen face direction) to part realizes.But, for some heavy parts, if adopt the clamping mode of this vertical direction, the processed position that has occupied part because of anchor clamps influences the processing of part, so just must carry out clamping, and this reduces the reliability of parts fixation easily at other position of part.Even on some part owing to can not find the position of clamping, and the temporary transient metal parts that is specifically designed to parts fixation that welds on part to be processed of having to, after finishing, part processing again this metal parts is removed, this will make the clamping of part comparatively bother, and increase the operation and the cost of part processing.For these parts, if can it be clamped from side direction (promptly parallel with platen face direction) enough anchor clamps, just will above-mentioned problem can not occur.

The utility model content

The purpose of this utility model provides a kind of heavy parts side direction clamping device, makes heavy parts can carry out side direction on the platen face and clamps.

Heavy parts side direction clamping device described in the utility model, form by clamp body and the drive screw and the sliding clamp that are arranged in clamp body, clamp body is made up of anchor clamps lower body and anchor clamps upper body fixed thereon, offer groove on the anchor clamps lower body, this groove forms a passage that runs through the clamp body two ends on clamp body; Respectively be provided with a boss at an end of anchor clamps lower body groove and an end of anchor clamps upper body, all offer semicircle breach on it, two boss are vertically opposite, make the two halves circumferential notch form a circular hole at an end of clamp body passage; Described sliding clamp is positioned at the other end and the clamp body matched in clearance of clamp body passage, makes sliding clamp only along this passage longitudinal sliding motion; Drive screw is arranged in the clamp body passage, and the one end passes from described circular hole, and with this circular hole matched in clearance, its in addition end spin with sliding clamp, and drive screw axis and clamp body passage axis are located on the same line; Drive screw is provided with two steps vertically, and the both sides that it lays respectively at the boss on anchor clamps upper body and the anchor clamps lower body can only be rotated drive screw around its axis.

Anchor clamps upper body and anchor clamps lower body fixedly combine as a whole by four bolts and two pins that are positioned at its four bights, thereby anchor clamps upper body and anchor clamps lower body fixedly can be joined together reliably.

At least three cover the utility model clamping devices are fixed on the platen face, and it is evenly arranged in around the processed heavy parts, with spanner rotating drive screw rod, because drive screw can only rotate around its axis in clamp body, thereby cause the sliding clamp of clamping device to move along clamp body passage vertically outside (part to be processed direction), the processing parts side is compressed, thereby the side direction that realizes part to be processed clamps.

Clamping device described in the utility model is simple in structure, uses easy to operately, can carry out side direction on lathe to heavy parts and clamp, and clamping is fixing very reliable.

The specific embodiment

Extremely shown in Figure 8 as Fig. 1, this heavy parts side direction clamping device is made up of clamp body and the drive screw 4 and the sliding clamp 2 that are arranged in clamp body, clamp body is made up of anchor clamps lower body 1 and anchor clamps upper body 3, anchor clamps upper body 3 and anchor clamps lower body 1 fixedly combine as a whole by four bolts 10 and two pins 6 that are positioned at its four bights, wherein two pins 6 are the diagonal layout on clamp body, fix with the positive connection that guarantees anchor clamps upper body 3 and anchor clamps lower body 1.Offer groove 11 on anchor clamps lower body 1, this groove 11 forms a passage 9 that runs through the clamp body two ends on clamp body.Respectively be provided with a boss 8 at an end of anchor clamps lower body groove 11 and an end of anchor clamps upper body 3, it is vertically opposite all to offer semicircle breach 12, two boss 8 on it, makes two halves circumferential notch 12 form a circular hole 7 at an end of clamp body passage 9.Described sliding clamp 2 is positioned at the other end and the clamp body matched in clearance of clamp body passage 9, makes sliding clamp 2 only along these passage 9 longitudinal sliding motions.Drive screw 4 is arranged in clamp body passage 9, and the one end passes from described circular hole 7, and with these circular hole 7 matched in clearance, its in addition end spin with sliding clamp 2, and drive screw 4 axis and clamp body passage 9 axis are located on the same line.Drive screw 4 is provided with two steps 5 vertically, and it lays respectively at the both sides of the boss 8 on anchor clamps upper body 3 and the anchor clamps lower body 1, thereby drive screw 4 can only be rotated around its axis.
