Description

Technical Field

[0001] This utility model belongs to the technical field of dust collection devices, and relates to a dust collection device for a five-axis machining center. Background Technology

[0002] A five-axis machining center adds two rotary axes (usually A and B axes) to the existing three linear axes (X, Y, and Z). This allows the tool or workpiece to operate in five degrees of freedom, enabling machining at any angle in space and producing complex shapes with high precision. However, five-axis machining centers generate significant amounts of dust and particulate matter during operation. If these substances remain suspended in the air for extended periods, they can negatively impact the respiratory health of employees, increasing the risk of occupational diseases. Furthermore, they can reduce visibility in the work area, affecting operational safety. Therefore, dust collection devices are necessary to remove these harmful substances and purify the air.

[0003] A dust collection device for a five-axis machining center disclosed in Chinese patent CN220637135U includes a base plate, a dust collection box fixedly connected to the top of the base plate, L-shaped support rods fixedly connected to the front and rear walls of the dust collection box near the left and right sides, the bottom end of the L-shaped support rods fixedly connected to the top of the base plate, a dust collection pump fixedly connected to the right wall of the dust collection box near the top, and an air suction pipe fixedly connected to the left side of the dust collection pump.

[0004] The dust collection device dries debris by blowing hot air into the dust collection box. Because debris accumulates on the top of the cover plate, and the five-axis machining center sprays coolant during workpiece processing, coolant adheres to the debris. As a result, some debris sticks to the cover plate and accumulates, making it difficult to dry the debris accumulated at the bottom.

[0005] To solve the above problems, this utility model proposes a dust collection device for a five-axis machining center. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a dust collection device for a five-axis machining center.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a dust collection box, the bottom of which is hinged to a sealing cover, and an arc-shaped elastic plate is slidably arranged at the top inside the sealing cover. The elastic plate is made of elastic material and gradually tilts upward from the middle to both ends.

[0008] The sealing cover is equipped with a driving component, which drives the elastic plate to bend downwards. The dust collection box is equipped with a dust collection component, and the side of the dust collection box is equipped with an air blowing component.

[0009] Furthermore, L-shaped bent plates slide through the two corresponding sides of the sealing cover, and the elastic plate is fixedly connected between the two bent plates. The other two sides of the elastic plate slide in cooperation with the inner wall of the sealing cover.

[0010] A sliding sleeve is fixedly connected to the middle of the bottom surface of the sealing cover, and a positioning rod is fixedly connected to the bottom of the elastic plate. The bottom end of the positioning rod is slidably disposed inside the sliding sleeve.

[0011] Furthermore, there are two drive components, each corresponding to a bending plate. Each drive component includes several cylinders, and the cylinders on each drive component are fixedly connected to the bottom of the sealing cover in a straight line at intervals.

[0012] Each cylinder's output end is fixedly connected to an elastic block, which is movably positioned at one end of the corresponding bending plate, and the elastic block abuts against the bending plate.

[0013] Furthermore, two limiting rods are symmetrically rotatably connected to the bottom of one side of the dust collection box. The two limiting rods are provided with grooves on the side where they are close to each other. A limiting block is fixedly connected to one side of the sealing cover, and the two grooves are respectively movably engaged with the two ends of the limiting block.

[0014] Furthermore, the vacuuming assembly includes an air pump, which is fixedly connected to one side of the vacuum chamber, and the suction end of the air pump extends into the vacuum chamber.

[0015] A suction pipe, which is a telescopic flexible hose, is fixedly inserted through the side of the dust collection box away from the suction pump.

[0016] Furthermore, the blowing assembly includes an annular air chamber, which is located on the side of the dust collection box. Several air holes are provided on the two corresponding inner walls of the dust collection box, and the air holes communicate with the air chamber. A heating wire is provided inside the air chamber.

[0017] A connecting pipe is fixedly connected to the bottom of the suction pipe near the bottom of the suction box. The other end of the connecting pipe is fixedly connected to the air chamber after passing through the side of the suction box. A filter plate is provided at the connection point between the top of the connecting pipe and the suction pipe.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The dust collection device of this five-axis machining center is equipped with an elastic plate. Dust and debris collected by the dust collection box fall onto the top of the elastic plate. Then, the cylinder is activated, and the output end of the cylinder pulls the elastic block closer to the bending plate. This pushes the two bending plates closer together, causing the elastic plate to bend downwards. Afterwards, the elastic block deforms and moves away from the bending plate, allowing the elastic plate to return to its original shape. The reciprocating movement of the elastic block causes the elastic plate to bend up and down repeatedly, which in turn pushes the debris on the elastic plate upwards, dispersing the debris and allowing hot air to blow onto more debris, resulting in a better drying effect.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-6As shown, the technical solution adopted by this utility model is as follows: A dust collection device for a five-axis machining center includes a dust collection box 1, and a sealing cover 7 is hinged to the bottom of the dust collection box 1 via a hinge 8. The sealing cover 7 seals the bottom of the dust collection box 1, facilitating the collection of dust and debris.

[0029] Two symmetrically rotatably connected limit rods 12 are located on one side of the bottom of the dust collection box 1, and grooves are provided on the sides of the two limit rods 12 that are close to each other. A limit block 13 is fixedly connected to one side of the sealing cover 7, and the two grooves are respectively movably engaged with the two ends of the limit block 13. By rotating the two limit rods 12, the grooves are engaged with the limit block 13, thus positioning the sealing cover 7 at the bottom of the dust collection box 1.

[0030] Each of the two limiting rods 12 is equipped with a torsion spring at one end that is rotatably connected to the dust collection box 1. The torsion spring drives the limiting rod 12 to abut against the limiting block 13. This facilitates the fixation of the limiting block 13 by the cooperation of the two limiting rods 12, thereby increasing the stability of the sealing cover 7.

[0031] An arc-shaped elastic plate 16 is slidably disposed at the top inside the sealing cover 7. The elastic plate 16 is made of elastic material and gradually slopes upward from the middle to both ends, so that the elastic plate 16 will bend when subjected to force.

[0032] L-shaped bent plates 4 slide through both sides of the sealing cover 7, and an elastic plate 16 is fixedly connected between the two bent plates 4. This allows the elastic plate 16 to be compressed by the bent plates 4. The other two sides of the elastic plate 16 slide against the inner wall of the sealing cover 7, allowing the elastic plate 16 to seal the top of the sealing cover 7, so that dust, debris, and other impurities fall onto the elastic plate 16.

[0033] A sliding sleeve 14 is fixedly connected to the center of the bottom surface of the sealing cover 7. A positioning rod 15 is fixedly connected to the bottom of the elastic plate 16, and the bottom end of the positioning rod 15 is slidably disposed inside the sliding sleeve 14. The elastic plate 16 is positioned by the cooperation of the positioning rod 15 and the sliding sleeve 14, thereby restricting the movement of the elastic plate 16 in the horizontal direction.

[0034] A drive assembly is provided on the sealing cover 7, which drives the elastic plate 16 to bend downward.

[0035] There are two drive assemblies, each corresponding to a bending plate 4. Each drive assembly includes several cylinders 11, which are fixedly connected to the bottom of the sealing cover 7 in a straight line at intervals.

[0036] Each cylinder 11 has an elastic block 5 fixedly connected to its output end. The elastic block 5 is movably mounted at one end of the corresponding bending plate 4, and the elastic block 5 abuts against the bending plate 4. The elastic block 5 is made of elastic material. The elastic block 5 will bend when subjected to force and will return to its original shape when the force is removed.

[0037] Several L-shaped support rods 3 are fixedly connected at intervals to the bottom of both sides of the dust collection box 1, and the bottom of the support rods 3 is fixedly connected to the same base plate 6. The base plate 6 is located below the sealing cover 7, and casters are fixedly installed at the four corners of the bottom surface of the base plate 6 to facilitate opening the sealing cover 7.

[0038] The vacuum chamber 1 is equipped with a vacuuming component, and the side of the vacuum chamber 1 is equipped with an air blowing component.

[0039] The vacuuming assembly includes an air pump 2, which is fixedly connected to one side of the vacuum chamber 1. The suction end of the air pump 2 extends into the vacuum chamber 1. The suction end of the air pump 2 extending into the vacuum chamber 1 is equipped with an inclined filter screen, which can prevent dust and other impurities from entering the suction end of the air pump 2.

[0040] A suction pipe 10 is fixedly inserted through the side of the dust collection box 1 away from the suction pump 2. The suction pipe 10 is a telescopic flexible hose, which allows the operator to hold the suction pipe 10 to vacuum the five-axis machining tool.

[0041] The air blowing assembly includes an annular air chamber 17, which is located on the side of the dust collection box 1. Several air holes 18 are provided on the two corresponding inner walls of the dust collection box 1, and these air holes 18 communicate with the air chamber 17. A heating wire is installed inside the air chamber 17. When the heating wire is energized, it heats the gas inside the air chamber 17.

[0042] A connecting pipe 9 is fixedly connected to the bottom of the suction pipe 10 near the bottom of the dust collection box 1. The other end of the connecting pipe 9 is fixedly connected to the air chamber 17 after passing through the side of the dust collection box 1. A filter plate 19 is provided at the connection point between the top of the connecting pipe 9 and the suction pipe 10. This allows air to pass through the filter plate 19 and enter the connecting pipe 9 during suction, and then enter the air chamber 17.

[0043] Working principle:

[0044] In use, the dust collection box 1 can be moved to the five-axis machining center using the casters at the bottom of the base plate 6. The heating wire inside the air chamber 17 is energized to heat the gas inside the air chamber 17.

[0045] Start the suction pump 2. The suction end of the suction pump 2 draws air from the dust collection box 1, causing the suction pipe 10 to generate suction. The operator moves one end of the suction pipe 10 to suck up dust, debris, and other impurities from the five-axis machining tool. The sucked-up impurities will fall onto the elastic plate 16.

[0046] Part of the gas drawn in by the suction pipe 10 is filtered through the filter plate 19 before entering the connecting pipe 9, then the air chamber 17, and finally discharged through the air hole 18. The discharged gas carries away the heat around the heating wire, thus forming hot air, which dries the impurities drawn in.

[0047] When cylinder 11 is activated, its output end pulls the elastic block 5 to one side of the bending plate 4, causing the elastic block 5 to push the two bending plates 4 closer together. This causes the middle part of the elastic plate 16 to bend downwards, while the positioning rod 15 slides downwards within the sliding sleeve 14.

[0048] After the positioning rod 15 slides to the bottom end inside the sliding sleeve 14, the elastic plate 16 can no longer bend downwards. At this time, if the elastic block 5 continues to move, it will bend and deform, causing the elastic block 5 to slide past the bottom end of the bending plate 4 and no longer push the bending plate 4. The elastic block 5 moves to the side where the two bending plates 4 are close to each other, and returns to its original shape after the elastic block 5 leaves the bending plate 4.

[0049] After the elastic plate 16 is no longer subjected to force, the elastic potential energy accumulated in the elastic plate 16 is released instantaneously, and the middle part of the elastic plate 16 will move upward to restore its original shape. This causes the positioning rod 15 to slide upward within the sliding sleeve 14. At the same time, the elastic plate 16 pushes the bending plate 4 to move, causing the two bending plates 4 to slide in opposite directions.

[0050] The output end of cylinder 11 pushes the elastic block 5, which has returned to its original shape, to move closer to the bending plate 4, and continues to push the bending plate 4 to move. After the positioning rod 15 slides to the top of the sleeve 14, the elastic plate 16 no longer deforms, and then the elastic block 5 will deform, causing the elastic block 5 to slide past the bending plate 4. The elastic block 5 is located on the side of the two bending plates 4 that are far apart from each other.

[0051] Furthermore, the reciprocating movement of the bending plate 4 causes the elastic plate 16 to bend up and down repeatedly. This causes dust, debris, and other impurities on the elastic plate 16 to bounce upwards, dispersing the debris and allowing hot air to blow towards more debris, resulting in a better drying effect.

[0052] This causes the debris piled on top of the elastic plate 16 to bounce up, and the debris stuck to the elastic plate 16 will come into contact with the hot air, so as to gradually dry the piled debris and make the drying more thorough.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
