Description

Water cutting quick die changing device

The technical field is as follows:

the utility model relates to an equipment accurate positioning technical field, specifically say a quick retooling device of water cutting.

Background art:

the current commonly-used positioning mode of the water cutting explorator bracket is round hole main positioning, and the round hole main positioning is added to limit the positioning of the elliptical hole in the X, Y direction, and a cylindrical positioning column is correspondingly designed on the water cutting base and is fixed on the water cutting base by bolts and positioning pins.

All adopt fork truck to carry under the normal condition and dismouting change, because fork truck is the level that hardly guarantees the forming relieved tooth and removes the location accuracy, so just there is following drawback in this kind of locate mode in-service use:

1. the matching and positioning precision of the hole of the water cutting explorator bracket and the cylinder on the water cutting base is high, so that the forklift is difficult to align and mount, the efficiency is low, and the operation technical requirement on a forklift worker is high;

2. when the water cutting explorator bracket is dismantled from the water cutting base, if fork truck can not keep the level to rise, but the slope just causes the damage to the reference column that can to influence the positioning accuracy of explorator.

The utility model has the following contents:

the utility model aims to overcome the defects of the prior art and provide a water cutting rapid die changing device; the main problem of current equipment structure require to fork truck personnel operating skill height, change efficiency slowly and process equipment positioning mechanism damage lead to the precision to lose etc. of solving.

The utility model provides a technical scheme is: the water cutting rapid die changing device comprises a water cutting base and a water cutting explorator bracket above the water cutting base, wherein a guide pillar is arranged on the water cutting base, a guide sleeve is arranged on the water cutting explorator bracket, and the guide pillar corresponds to the guide sleeve in position; the water cutting machine is characterized in that a cylinder is arranged below the guide pillar, the cylinder is connected with a pneumatic reversing valve on the water cutting base through an air pipe to control the cylinder to extend and retract, and therefore a cylinder rod of the cylinder drives the guide pillar to lift in the water cutting base; a wedge-shaped limiting block is arranged on the periphery of the water cutting base, and the distance between the wedge-shaped limiting block and the water cutting explorator bracket is 8 mm; the upper end of the guide post is chamfered with a C10 bevel.

The utility model has the advantages that: 1. on the basis of keeping a conventional forklift die changing tool (not a special balance device), a guide pillar and guide sleeve matching mode is still adopted, the original fixing mode of the guide pillar is changed into a lifting mode driven by an air cylinder, when the water cutting explorator is disassembled, the guide pillar is retracted into the base and separated from the explorator bracket, and a forklift driver can easily fork the explorator without damaging the guide pillar; 2. design wedge stopper all around on the water cutting base, simultaneously at the guide pillar upper end oblique angle of falling C10 for during the cylinder drives the guide pillar and goes up can be by oneself leading and get into the guide pin bushing, reach the light accurate positioning of water cutting profiling bracket, easily operation, it is efficient.

Description of the drawings:

FIG. 1 is a schematic view of the structure of the guide pillar in a descending state;

fig. 2 is a schematic diagram of the ascending state structure of the guide pillar of the present invention.

The specific implementation mode is as follows:

for a better understanding and practice, the following detailed description of the embodiments is given in conjunction with the accompanying drawings; the examples are given solely for the purpose of illustration and are not intended to limit the scope of the invention.

As shown in fig. 1 and 2, the water cutting rapid die changing device comprises a water cutting base 1 and a water cutting explorator bracket 2 arranged above the water cutting base, wherein a guide sleeve 4 is fixedly arranged on the water cutting explorator bracket 2; a guide pillar 3 is installed in the water cutting base 1, an air cylinder 5 is installed below the guide pillar 3, a pneumatic reversing valve is installed at any position on the water cutting base 1, which is convenient to operate, the pneumatic reversing valve is connected with the air cylinder 5 through an air pipe and used for controlling the stretching out and retracting of the air cylinder 5, an air cylinder rod of the air cylinder 5 drives the guide pillar 3 to lift in the water cutting base 1, and the guide pillar 3 corresponds to a guide sleeve 4 in position; a wedge-shaped limiting block 6 (C15 oblique angle) is fixed on the periphery of the water cutting base 1, and the distance between the wedge-shaped limiting block 6 and the water cutting explorator bracket 2 is 8 mm; the upper end of the guide post 3 is chamfered by a C10 angle.

The utility model adopts the matching mode of the guide post and the guide sleeve, when the water cutting explorator is disassembled, the guide post is retracted into the base to be separated from the explorator bracket, so that a forklift driver can easily fork the explorator without damaging the guide post (as shown in figure 1); the forklift aims to solve the problems of difficult installation and alignment and low efficiency of the forklift; on one hand, wedge-shaped limit blocks (C15 oblique angles) are designed on the periphery of the water cutting base and are 8mm away from the water cutting explorator bracket, and on the other hand, the C10 oblique angle is inverted at the upper end of the guide pillar, so that the guide pillar can be guided into the guide sleeve by self when the guide pillar is driven by the cylinder to ascend, and the water cutting explorator bracket can be easily and accurately positioned (as shown in figure 2); the method comprises the following specific operation steps:

1. a forklift worker can place the water cutting explorator bracket in the range of the wedge-shaped limiting block on the periphery of the water cutting base without aligning the position of the guide pillar;

2. the pneumatic reversing valve is rotated, the cylinder drives the guide pillar to ascend, and the guide pillar automatically enters the guide sleeve through the front end chamfer, so that the requirement of repeated and accurate positioning of the water cutting explorator bracket is met;

3. when the explorator bracket needs to be replaced and disassembled, the pneumatic reversing valve is rotated, and the guide pillar is driven by the cylinder to descend;

fork truck personnel can be light pick up and transport away water cutting profiling bracket.
