Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a high-pressure water cutting machine. Background Art

[0002] A water jet cutting machine is a machine that uses high-pressure water jets to cut. The principle of a water jet cutting machine is to use high-pressure energy-storing water. When it is ejected from a nozzle, the high-pressure potential energy is converted into high-speed kinetic energy. If some solid hard particles are added to the water jet, called water jet abrasives, it will have greater energy and can cut hard and thick materials. The kinetic energy of the water is transferred to the abrasive sand particles by accelerating the abrasive sand. The abrasive sand particles with high-speed kinetic energy hit the object to be cut, rubbing and peeling off the material of the object to be cut from a microscopic perspective, and extending downward along the thickness of the material little by little until it penetrates. Water cutting does not produce harmful gases or liquids, and does not generate heat on the surface of the workpiece. It is a truly multifunctional, high-efficiency cold cutting process, and is widely used in mechanical processing. Existing water jet cutting machines usually cannot fix the workpiece to be processed during the processing process, so that the workpiece to be processed is easy to shake under the impact of the water jet during the processing, reducing the cutting efficiency and cutting quality. Utility Model Content

[0003] The utility model aims to provide a high-pressure water cutting machine, which can fix the workpiece to be processed during the processing, avoid the workpiece to be processed from shaking randomly during the processing, and improve the cutting quality.

[0004] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: it includes a workbench, a guide rail fixed to the workbench and a cutting head body sliding on the guide rail, a plurality of support plates are evenly fixed on the workbench, and first adjusting screws arranged along the axial direction of the workbench are rotatably connected on both sides of the workbench, the first adjusting screw is driven to rotate by a driving mechanism installed on the workbench, the first adjusting screws on both sides are threadedly connected to a fixed seat, a driving cylinder perpendicular to the first adjusting screw is installed on the fixed seat, the driving cylinders on both sides are mirror-imaged, a clamping member is fixed to the output end of the driving cylinder, and the clamping member includes a fixing member, a clamping plate fixed to the fixing member, a pushing plate sliding on the bottom end of the clamping plate and a pressing plate sliding on the fixing member.

[0005] By adopting the above technical scheme, the workpiece to be processed is placed on multiple support plates of the workbench, and the driving mechanism drives the first adjusting screw to rotate. The rotation of the first adjusting screw drives the fixed seat to move forward and backward relative to the workbench, so as to adjust the relative position of the clamping member and the workpiece to be processed according to the size of the workpiece to be processed. After adjustment, the driving cylinder is started, and the piston rod of the driving cylinder is extended to drive the clamping members on both sides of the workpiece to move toward the workpiece. Finally, the clamping plate clamps both sides of the workpiece and the pressure plate presses the workpiece onto the support plate to avoid the workpiece to be processed from shaking under the impact of the water jet during the processing, thereby improving the cutting efficiency and cutting quality. After the cutting work is completed, the driving cylinder on one side can be driven to return, and the output end of the driving cylinder on the other side can continue to extend, pushing the workpiece to one side of the workbench for the convenience of staff to unload the material. The clamping plate and the push plate increase the contact area with the workpiece, and jointly push the workpiece to move, thereby improving the unloading stability.

[0006] The utility model is further configured as follows: the driving mechanism comprises a driving motor installed on the workbench, the driving motor drives the first adjusting screw on one side to rotate, and a belt is transmitted between the first adjusting screws on both sides.

[0007] By adopting the above technical solution, when adjusting the position of the clamping member relative to the workbench, the driving motor drives the first adjusting screw on one side to rotate, and the first adjusting screws on both sides rotate synchronously through the belt to achieve the common adjustment of the positions of the clamping members on both sides.

[0008] The utility model is further configured as follows: a cavity is provided at the bottom of the clamping plate for the push plate to slide into, a telescopic spring is fixed between one end of the push plate located in the cavity and the inner wall of the cavity, and both sides of the bottom end of the push plate are chamfered.

[0009] By adopting the above technical solution, the pushing plate slides out relative to the clamping plate and is located between the gaps of adjacent support plates. When the first adjusting screw rotates to drive the clamping piece to move relative to the workbench and the bottom end of the clamping plate passes through the support plate, the pushing plate slides relative to the clamping plate and contracts into the cavity. After passing the support plate, the pushing plate slides out of the cavity and resets itself under the action of the telescopic spring, thereby increasing the contact area with the workpiece when pushing the plate and making the pushing and unloading process more stable.

[0010] The utility model is further configured as follows: a guide rod inserted and slidably connected to the fixing member is fixed on the upper end of the pressing plate, and a compression spring sleeved on the outside of the guide rod is fixed between the pressing plate and the fixing member.

[0011] By adopting the above technical solution, when the driving cylinder drives the clamping part to move to both sides of the workpiece, the pressure plate contacts the upper end of the workpiece to press the workpiece downward. When the thickness of the workpiece changes, the pressure plate rises and falls relative to the fixing part to adjust the distance between the bottom end of the pressure plate and the support plate. When the driving cylinder returns, the pressure plate is reset under the action of the clamping spring and the guide rod.

[0012] The utility model is further configured as follows: a side of the pressing plate away from the driving cylinder is chamfered twice.

[0013] By adopting the above technical solution, when the driving cylinder drives the clamping part to move to both sides of the workpiece, the workpiece drives the pressing plate to rise and fall relative to the fixing part through chamfering, so that the pressing plate contacts the upper end of the workpiece and presses the workpiece onto the support plate.

[0014] The utility model is further configured as follows: two guide rods are provided, and a connecting rod is fixed between the ends of the two guide rods extending out of the pressure plate.

[0015] By adopting the above technical solution, the lifting stability of the pressure plate is enhanced. At the same time, when one side drives the cylinder to return and the output end of the other side drives the cylinder to extend and continue to push the workpiece to one side of the workbench, the staff can lift the pressure plate through the connecting rod to facilitate the removal of the workpiece from the clamp.

[0016] The utility model is further configured as follows: an adjusting component for driving the cutting head body to rise and fall is installed on the guide rail.

[0017] By adopting the above technical solution, the adjustment component can change the height of the cutting head body relative to the workpiece according to the thickness of the workpiece to be processed, so as to achieve appropriate cutting accuracy.

[0018] The utility model is further configured as follows: the adjustment assembly includes a slide seat slidably connected to the guide rail, a second adjustment screw rotatably connected to the slide seat, the two ends of the second adjustment screw are set with opposite threads, the two ends of the second adjustment screw are threadedly connected with moving blocks, and a connecting rod is hinged between the two moving blocks and the cutting head body.

[0019] By adopting the above technical solution, the second adjusting screw is rotated to drive the movable blocks on both sides to move relative to each other, thereby changing the distance between the upper ends of the two connecting rods, thereby changing the height of the bottom ends of the connecting rods. The bottom ends of the two connecting rods jointly drive the cutting head body to rise and fall, thereby adjusting the height between the cutting head body and the workpiece to be processed.

[0020] The utility model is further configured as follows: a rotating handle is fixed to one end of the second adjusting screw extending out of the sliding seat.

[0021] By adopting the above technical solution, it is convenient to rotate the second adjusting screw.

[0022] The utility model is further configured as follows: limiting grooves are provided on both sides of the slide seat along the vertical direction, and limiting plates embedded in the limiting grooves are fixed on the cutting head body.

[0023] By adopting the above technical solution, when the cutting head body is lifted or lowered relative to the slide seat, the limit plate is lifted or lowered in the limit groove to limit and guide the cutting head body.

[0024] The beneficial effects of the utility model are:

[0025] 1. Place the workpiece to be processed on multiple support plates of the workbench. The first adjusting screws on both sides rotate to drive the fixed seat to move forward and backward relative to the workbench, so as to adjust the relative position of the clamping piece and the workpiece to be processed according to the size of the workpiece to be processed. After adjustment, the piston rod of the driving cylinder extends to drive the clamping pieces on both sides of the workpiece to move toward the workpiece. Finally, the clamping plate clamps both sides of the workpiece, and the pressing plate presses the workpiece onto the support plate to prevent the workpiece from shaking under the impact of the water jet during the processing, thereby improving the cutting efficiency and cutting quality.

[0026] 2. After the cutting work is completed, the driving cylinder on one side can be driven to return, and the output end of the driving cylinder on the other side can continue to extend, pushing the workpiece to one side of the workbench for easy unloading by the staff. The clamping plate and the push plate increase the contact area with the workpiece, jointly push the workpiece to move, and improve the unloading stability;

[0027] 3. Turn the second adjusting screw to drive the moving blocks on both sides to move relative to each other, change the distance between the upper ends of the two connecting rods, and thus change the height of the bottom ends of the connecting rods. The bottom ends of the two connecting rods jointly drive the cutting head body to rise and fall, and adjust the height between the cutting head body and the workpiece to be processed to achieve appropriate cutting accuracy.
