(2) The bottom of slide is provided with guide boss and limiting plate, and guide boss can guarantee that the slide removes along the guide rail direction, prevents to take place the skew in the in-process position that removes, and the limiting plate makes slide bottom card in the inslot of guide rail, can prevent to drop from the guide rail at the in-process slide that removes. In addition, when the pump is in operating condition, constantly shake during the pump, the limiting plate can prevent the pump that shakes from driving the slide to drop from the guide rail.
(3) The contact surfaces of the clamping grooves of the limiting clamping plates and the sliding plates, which are mutually attached, are inclined planes. When the limiting clamping plate clamps the sliding plate, the sliding plate only needs to be slightly moved a small distance when the sliding plate needs to be moved outwards, the sliding plate and the clamping groove are not contacted any more, the sliding plate can be moved continuously, and the rapid loading and unloading function is achieved.
After the limiting clamping plate is fixed at the position once, the position of the pump in the shaping table does not need to be repeatedly determined every time the pump is replaced or maintained, and the sliding plate carrying the pump body cannot move continuously when moving to the limiting clamping plate, namely the designated position of the pump in the shaping table.
The gap is arranged between the limiting clamping plate and the sliding plate, and the wedge-shaped limiting clamping plate inclined surface is mainly contacted with the sliding plate inclined surface to play a role in compression. But the vacuum pump can shake when working, and the fixed plate is pressed by the wedge-shaped limiting clamping plate inclined plane and the elbow clamp, so that the fixed plate becomes stable.
(4) The elbow presss from both sides the setting in the position department that is close to the setting table entry, when changing or maintenance pump, the staff need not enter into setting table inside just can remove the pressure of elbow clamp to the slide, removes this pressure, and the staff just can very conveniently move the pump to the outside maintenance or the change of setting table.
The interior space of the shaping table is small, the pump is not allowed to be replaced in the shaping table, and workers are difficult to enter the shaping table to move the pump to the outside for maintenance or replacement, so that the working difficulty is reduced.
(5) The spanner type quick-change male head and the spanner type quick-change female head are matched for use, so that the pump body and the equipment hose can be quickly connected or detached, and further the pump body can be conveniently and quickly maintained or replaced.
(6) The stopper mutually supports with spacing cardboard, the position of the pump body in the design platform that can be better is fixed, prevents that the pump body position of shake from taking place the skew. When the bolt that leads to fixed spacing cardboard because the shake of the pump body rotates, because the length of stopper along slide at guide rail direction of movement is greater than the groove width of guide rail for even the pump body shakes, because stopper and bolt fixed connection, the stopper also can prevent not hard up bolt rotation, and then fix spacing cardboard, finally realize fixing the purpose of slide.
(7) The upper end of the C-shaped guide rail is a horizontal supporting surface, so that the guide rail is in surface contact with the sliding plate, and the firmness of the pump body arranged on the sliding plate can be improved.
(8) The hook tip of the C-shaped guide rail faces downwards, the limiting plate of the sliding plate is located below the hook tip, the width of the limiting plate is larger than the distance between the two hook tips and slightly smaller than or equal to the groove width of the guide rail, when the pump body mounted on the sliding plate is in an open state, strong vibration exists, the limiting plate is matched with the guide rail in a related mode, the position of the sliding plate can be better fixed, and then the position of the pump body can be better fixed.
