Description

Technical Field

[0001] The present invention relates to the technical field of numerical control machine tool cutting, and particularly relates to an adjustable multi-angle water jet cutting multifunctional fixture. Background Art

[0002] At present, during water jet cutting, vertical cutting is mostly adopted. The material mainly bears the force in the vertical direction, and the force in the horizontal direction is very small. Generally, large fixed fixtures are not required. However, when cutting workpieces with small mass and special shapes, heavy objects are needed to press the parts during cutting to prevent the cutting water flow from shooting into the water tank and causing the water flow in the water tank to surge, resulting in reverse impact and damaging the workpiece positioning, and to prevent the special shape of the workpiece or the special processing shape from affecting the processing accuracy.

[0003] Most of the existing workpiece fixing devices for water jet cutting clamp the end of the workpiece by setting clamping components, and the clamping and fixing effects on the workpiece itself and the side are relatively poor. Moreover, the positions of the clamping components are fixed, which is not conducive to accurately positioning and adjusting the workpiece. Moreover, when cutting at a required angle, the existing equipment often cannot meet the cutting angle requirements. Summary of the Invention

[0004] The purpose of the present invention is to provide an adjustable multi-angle water jet cutting multifunctional fixture, which can realize multi-angle cutting of plate parts and multi-angle impact tests of plate materials at low energy.

[0005] The technical solution adopted by the present invention is as follows:

The bottom surface of the short part of the lower L-shaped plate is fixed on the upper end surface of the frame through a first hinge. The upper L-shaped plate is arranged parallel to the lower L-shaped plate, and their long and short parts correspond. The bottom surface of the long part of the upper L-shaped plate is fixedly connected to the top surface of the long part of the lower L-shaped plate through a second hinge.

The upper L-shaped plate is slidably connected to the lower L-shaped plate through the first cross-connecting slider and the second cross-connecting slider, and the figure formed by the upper L-shaped plate and the lower L-shaped plate is a rectangle or a square. The T-shaped clamping plate is slidably and fixedly arranged on the upper guide rail and the lower guide rail for clamping and fixing the test piece.

[0007] The described T-shaped splints are multiple and are respectively slidably arranged on the upper guide rail and the lower guide rail through sliders. The upper end surfaces of the T-shaped splints arranged on the lower guide rail and the upper end surfaces of the T-shaped splints arranged on the upper guide rail are in the same plane. The horizontal part of the T-shaped splint is a fixed part for fixing with the slider, and a crimping bolt for fixing the test piece is arranged on the short part.

[0008] It further includes a first telescopic support rod and a second telescopic support rod. The top of the first telescopic support rod is in contact with the bottom of the long part of the lower L-shaped plate, and the top of the second telescopic support rod is in contact with the bottom of the short part of the upper L-shaped plate, which are respectively used to change the angle between the long part of the lower L-shaped plate and the upper end surface of the frame and the angle between the short part of the upper L-shaped plate and the plane where the lower L-shaped plate is located.

[0009] The first telescopic support rod includes a support rod and a first auxiliary telescopic rod.

[0010] It further includes an auxiliary telescopic rod. One end of the auxiliary telescopic rod is hinged to the free end of the first auxiliary telescopic rod in the telescopic support rod, and the other end is fixed to the first hinge corresponding to the upper L-shaped plate or the second hinge corresponding to the lower L-shaped plate in contact with the first auxiliary telescopic rod.

[0011] It further includes a anti-drop part net, which is detachably arranged under the frame and is used for buffering and collecting the cut test pieces.

[0012] An L-shaped missing part is arranged on the anti-drop part net, and the L-shaped missing part corresponds to the cutting of the tool.

[0013] Scale pointers are fixedly arranged on one end surfaces of the rotating shafts of the first hinge and the second hinge, which are used to indicate the rotation angle of the hinge rotating shaft.

Multiple T-shaped splints are arranged on the slide rails, so that test pieces of different sizes can be clamped, thus facilitating the cooperation with the existing vertical water jet numerical control machine tool. At the same time, due to the above-mentioned hinged structure setting, the three-dimensional multi-angle changes after the test piece is clamped can be satisfied, and then the water jet cutter head of the vertical water jet numerical control machine tool is used to realize the translation in the XYZ three axes of space for cutting, realizing the clamping effect of the multi-angle cutting experiment of the test piece, and greatly expanding the actual use range and function of the existing vertical water jet numerical control machine tool.

The upper and lower end surfaces of the first cross-connecting slider and the second cross-connecting slider are respectively provided with chutes that cooperate with the upper guide rail 3 and the lower guide rail 2. The upper L-shaped plate 5 is slidably connected to the lower L-shaped plate 4 through the first cross-connecting slider and the second cross-connecting slider, and the figure formed by the upper L-shaped plate 5 and the lower L-shaped plate 4 is a rectangle or a square. The T-shaped clamp 6 is slidably and fixedly arranged on the upper guide rail 3 and the lower guide rail 2 for clamping and fixing the test piece. In actual use, the guide rails are fixed to the corresponding plates through guide rail fastening bolts 8.

[0021] The T-shaped splints 6 are multiple and are respectively arranged on the upper guide rail 3 and the lower guide rail 2 by sliding with sliders. The upper end faces of the T-shaped splints arranged on the lower guide rail 2 and the upper end faces of the T-shaped splints arranged on the upper guide rail 3 are in the same plane. The horizontal part of the T-shaped splint is a fixed part for fixing with the slider, and a crimping bolt 7 for fixing the specimen is arranged on the vertical part.

[0022] It further includes a first telescopic support rod 19 and a second telescopic support rod 14.

[0023] Scaled pointers are also arranged on the first hinge and the second hinge. When the scaled pointers rotate to the required angles, the first flat hinge first fastening nut 18 and the second fastening nut 23 at the back are locked, so as to cooperate with the first telescopic support rod 19 and the second telescopic support rod 14 to fix the angle of the specimen and make the overall processing process stable without change.

[0024] The first telescopic support rod 19 includes a support rod and a first auxiliary telescopic rod. The first auxiliary telescopic rod is vertically sleeved with the support rod, and a limit bolt 22 is transversely arranged on the support rod for fixing the extended height of the first auxiliary telescopic rod. Similarly, the second telescopic support rod 14 has the same structure, and a limit bolt 17 is transversely arranged on the support rod for fixing the extended height of the first auxiliary telescopic rod.

[0025] It further includes an auxiliary telescopic rod. One end of the auxiliary telescopic rod is hinged to the free end of the first auxiliary telescopic rod in the telescopic support rod, and the other end is fixed to the second hinge corresponding to the upper L-shaped plate in contact with the first auxiliary telescopic rod or the first hinge corresponding to the lower L-shaped plate.

Specifically, the one end of the auxiliary telescopic rod hinged to the free end of the first auxiliary telescopic rod in the telescopic support rod adopts a spherical hinge 16, which can make the two rotate more flexibly when stressed. Moreover, by using the spherical hinge 16 and the pin shaft 21 in combination, the rotation angles of the two planes can be made non-interfering with each other.

[0026] It further includes a parts-drop prevention net 27, which is detachably arranged below the frame and used for buffering and collecting the cut test pieces. During actual use, a parts-drop prevention net slide rail 26 is arranged on the frame, so that the parts-drop prevention net 27 can be disassembled in a pull-out manner, which is convenient and fast. On the frame 1, a machine tool origin positioning reference port 28 is arranged at the included angle position of the upper and lower L-shaped plates, which is used for positioning the starting position of the machine tool water jet, and further provides a standard for the subsequent cutting path development and the positioning and clamping of the clamped plate.

[0027] An L-shaped missing part is arranged on the parts-drop prevention net, and the L-shaped missing part corresponds to the tool cutting.

[0028] On one end face of the rotating shafts of the first hinge 11 and the second hinge 10, scale pointers are fixedly arranged to represent the rotation angle of the hinge rotating shaft.

[0029] The present invention can be used for multi-angle cutting of plate parts and multi-angle impact tests of plate materials at low energy. It includes a frame, two slide rails are welded below the frame, and there is a parts-drop prevention net between the slide rails, which can be used to prevent smaller test pieces from falling into the water tank during water jet cutting. The fixture body is two L-shaped steel plates that can slide relatively parallel to each other and are connected by bolts to the slide rails. The size of the plate test piece can be adjusted by changing the relative positions of the two slide rails. A clamping device T-shaped clamping plate with bolts is also connected to the slide rails. After installing the plate part, it is fixed with the T-shaped clamping plate. One L-shaped slide rail of the fixture body can be rotated around a hinge with a scale disk to adjust the included angle between the normal direction of the test piece and the axial direction of the tool spindle. The cooperation of the support rod and the auxiliary telescopic rod plays a role in supporting and positioning the fixture body.

[0030] In use, first perform fixture positioning. After placing the fixture on the workbench, when the two rotating planes of the fixture body are in the horizontal plane, that is, when the scale pointers of the scale pointers are all adjusted to 0, align the machine tool origin positioning reference port 28 with the water jet cutter head, and set this point as the working origin. The relative position between the guide rail of the fixture body and the machine tool origin positioning reference port 28 is designed and remains unchanged. Calculate and draw the water jet cutting trajectory when the angle is horizontal. Then perform workpiece positioning. First, place the rectangular plate to be cut in the clamping area enclosed by the two L-shaped plates fixed on the upper and lower guide rails. After adjusting the size in cooperation with the cross-connecting slider 9, position each of the four sides with the slidable T-shaped clamping plates 6, and tighten the slider pressing bolts 7 for fixation. Then, slowly lift the fixture body fixing the processed plate by hand and rotate it around the first hinge 11 and / or the second hinge 10 of the plane, so that it drives the corresponding hinge shaft to rotate and makes the first auxiliary telescopic rod 15, the second auxiliary telescopic rod 20, the first telescopic support rod, and the second telescopic support rod 14 extend. When the scale pointers on the second scale pointer 12 and / or the first scale pointer 13 rotate to the required angle, lock the first fastening nut 18 and the second fastening nut 23 of the rear plane hinge. At the same time, lock the first telescopic support rod fastening bolt and the second telescopic support rod fastening bolt under the second telescopic support rod 14 and the first telescopic support rod 19 to keep the plate to be processed and the fixture fixed at a certain angle. Moreover, the angles of the two planes can be adjusted to achieve processing at different spatial positions. During processing, the anti-drop part net 27 first withdraws from the processing area. When the plate specimen is almost processed, pull the anti-drop part net 27 provided under the frame 1 along the anti-drop part net slide rail 26 into the working area. The preset final processing route processes the last cutting path in the L-shaped area of the anti-drop part net 27, which can prevent the workpiece from falling into the water tank or on the ground.
