Description

Technical Field

[0001] The invention relates to the technical field of particle material spraying, in particular to a numerically controlled precision sandblasting device. Background Art

[0002] The sandblasting machine uses compressed air as its power. The high-speed movement of the airflow forms a negative pressure in the spray gun, which sucks the abrasive into the spray gun through the sand conveying pipe and ejects it through the nozzle, spraying it onto the processed surface to achieve the desired grinding effect.

[0003] Cited by China Publication No. CN221539435U, the patent discloses a CNC blade sandblasting equipment, which belongs to the field of sandblasting machine technology. Its technical points are: including a frame, a reciprocating component, a flipping component and a sliding component. Place the blade on the placement rack, turn on the sandblasting machine body, so that the sandblasting machine body can perform sandblasting and rust removal on the blade. Turn on the reciprocating component, the reciprocating component can drive the placement rack to slide back and forth in the frame, the reciprocating component can flip under the action of the flipping component, and when the reciprocating component contacts the sliding component, the reciprocating component can slide alternately under the action of the sliding component, so that the reciprocating component drives the placement rack to flip alternately in sequence.

[0004] The above patent uses an alternating flipping method to perform sandblasting on metal materials. However, the above sandblasting equipment has some shortcomings when processing metal materials. The metal materials are not flipped sufficiently during the sandblasting process, resulting in uneven sandblasting. The sandblasting operation needs to be repeated many times, thereby reducing the efficiency of sandblasting and grinding. In addition, for some irregularly shaped metal materials, it is difficult to effectively process all surfaces during the sandblasting process. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a numerically controlled precision sandblasting device to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a CNC precision sandblasting device, comprising a fixed seat, a sandblasting pot is fixedly connected to the front of the fixed seat, a CNC sandblasting device is fixedly connected to the outer wall of the sandblasting pot, and a bumping mechanism is also fixedly connected to the front of the fixed seat; The jolting mechanism comprises: The left side of the bumping bucket is rotatably connected to the front side of the fixed seat. The motor in the bumping mechanism drives the disc to rotate, which in turn causes the bumping bucket to produce a bumping motion, causing the metal material to continuously roll in the bucket. Due to the large inertia generated by the heavy weight of the metal material itself, it can smoothly leak out of the accumulated sand, ensuring that all surfaces of the metal material can be evenly sandblasted. Compared with traditional equipment, it greatly reduces rework caused by uneven sandblasting, and effectively improves the sandblasting quality and production efficiency; A motor, wherein the motor is fixedly connected to the outer wall of the fixing seat; A disc, the outer wall of which is rotatably connected to the outer wall of the motor, and the disc is rotatably connected to the jolting bucket; A guide assembly is fixedly connected to the back side of the jolting bucket.

[0007] The jolting bucket is arranged in a triangular shape with an opening at the top, and the numerically controlled sandblasting device is inclined toward the jolting bucket.

[0008] A third bearing is rotatably connected between the left side of the jolting bucket and the fixed seat, and a first bearing is rotatably connected to the bottom of the jolting bucket.

[0009] Preferably, a second bearing is rotatably connected to the outer wall of the disk at a position offset from the center of the circle, and a long rod is rotatably connected between the first bearing and the second bearing.

[0010] Preferably, the guide assembly includes a guide ring, the outer wall of which is fixedly connected to the front side of the fixing seat, and the back side of the bump bucket is fixedly connected to a guide rod. The cooperation between the guide rod and the guide ring in the guide assembly limits the range of movement of the bump bucket, making the movement of the bump bucket more stable and regular under the drive of the motor. This not only ensures the structural stability of the equipment during long-term operation, reduces the risk of component wear and failure caused by excessive shaking, but also enables the CNC sandblasting device to more accurately spray sandblasting materials onto the surface of the metal material, further improving the quality and efficiency of sandblasting.

[0011] Preferably, the guide rod is inserted into the guide ring, and the guide ring restricts the guide rod to only make circular motion, and a bracket is fixedly connected between the guide ring and the fixing seat.

[0012] Preferably, an auxiliary mechanism is fixedly connected to the front side of the fixing seat away from the top of the jolting bucket.

[0013] Preferably, the auxiliary mechanism includes a temporary storage box, which is fixedly connected to the front side of the fixed base at a position away from the top of the jolting bucket, a magnetic block is inserted into the top of the temporary storage box, a fan is fixedly connected to the outer wall of the temporary storage box, and a movable component is fixedly connected to the bottom of the temporary storage box. An air flow port is opened at the bottom of the temporary storage box. When the fan of the auxiliary mechanism is working, the magnetic block on the top of the temporary storage box can absorb magnetic impurities such as iron filings generated by sandblasting of metal materials, so that impurities in the sandblasting process can be removed in time, reducing the influence of debris and impurities on the sandblasting effect, ensuring the continuity of the sandblasting operation, and reducing the downtime due to cleaning impurities, thereby improving the overall sandblasting operation efficiency.

[0014] Preferably, a door panel is clamped on the outer wall of the temporary storage box.

[0015] Preferably, the movable component includes a zigzag tube, which is fixedly connected to the bottom of the fan, and a suction bin is fixedly connected to the bottom of the zigzag tube. The triangular shape of the bump bucket and the matching structure of its internal guide groove and the suction bin enable the equipment to better handle metal materials of different shapes and sizes. No matter whether it is block, columnar or other irregularly shaped metal materials, they can fully contact with the sandblasting material during movement in the bump bucket, and impurities can also be effectively cleaned, which broadens the application scope of the equipment and improves the efficiency of the equipment in different metal material processing scenarios. The inner wall of the bump bucket is fixedly connected to a guide groove, and the suction bin is clamped in the guide groove, and the movement of the suction bin is driven by the movement of the bump bucket.

[0016] The present invention provides a numerically controlled precision sandblasting device, which has the following beneficial effects: 1. The CNC precision sandblasting equipment uses the motor in the bumping mechanism to drive the disc to rotate, thereby causing the bumping bucket to produce a bumping motion, causing the metal material to continuously roll in the bucket. Due to the large inertia caused by the heavy weight of the metal material itself, it can smoothly leak out from the accumulated sand, ensuring that all surfaces of the metal material can be evenly sandblasted. Compared with traditional equipment, it greatly reduces the rework caused by uneven sandblasting, effectively improves the sandblasting quality and production efficiency, and through the control of CNC components, the CNC sandblasting device can perform precision sandblasting.

[0017] 2. When the fan of the auxiliary mechanism of the CNC precision sandblasting equipment is working, the magnetic block on the top of the temporary storage box can absorb the magnetic impurities such as iron filings generated by the sandblasting of metal materials, so that the impurities in the sandblasting process can be removed in time, reducing the influence of debris and impurities on the sandblasting effect, ensuring the continuity of the sandblasting operation, reducing the downtime due to cleaning impurities, and thus improving the overall sandblasting operation efficiency.

[0018] 3. The CNC precision sandblasting equipment limits the range of motion of the bump bucket by the cooperation of the guide rod and the guide ring in the guide assembly, making the movement of the bump bucket more stable and regular under the drive of the motor. This not only ensures the structural stability of the equipment during long-term operation, reduces the risk of component wear and failure caused by excessive shaking, but also enables the CNC sandblasting device to spray sandblasting materials onto the surface of metal materials more accurately, further improving the quality and efficiency of sandblasting.

[0019] 4. The CNC precision sandblasting equipment, through the triangular design of the bumping bucket and the matching structure of its internal guide groove and the suction bin, can better handle metal materials of different shapes and sizes. Whether it is block, column or other irregular shaped metal materials, they can fully contact with the sandblasting material during movement in the bumping bucket, and impurities can be effectively cleaned, which broadens the scope of application of the equipment and improves the efficiency of the equipment in different metal material processing scenarios.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] For example, see Figure 1-5 The present invention provides a technical solution: a CNC precision sandblasting device, comprising a fixed seat 1, a sandblasting pot 2 is fixedly connected to the front of the fixed seat 1, a CNC sandblasting device 3 is fixedly connected to the outer wall of the sandblasting pot 2, and a bumping mechanism 4 is also fixedly connected to the front of the fixed seat 1; In the above, a numerical control component is provided on the fixing base 1, so that various devices can be controlled; The metal material to be sandblasted is placed in the jolting bucket 41. The sandblasting pot 2 is used as a storage container for the sandblasting material. The sandblasting material inside the sandblasting pot 2 is sprayed toward the metal material in the jolting bucket 41 through the CNC sandblasting device 3 under a certain pressure. The CNC sandblasting device 3 is tilted toward the jolting bucket 41 to ensure that the sandblasting material can cover the surface of the metal material in the jolting bucket 41. The bumping mechanism 4 comprises: A bump bucket 41, the left side of which is rotatably connected to the front side of the fixing base 1; A motor 45, the motor 45 is fixedly connected to the outer wall of the fixing base 1; The disc 44, the outer wall of the disc 44 is rotatably connected to the outer wall of the motor 45, and the disc 44 is rotatably connected to the bump bucket 41; The guide assembly 46 is fixedly connected to the back side of the jolting bucket 41 .

[0025] The jolting bucket 41 is triangular in shape and open at the top. The CNC sandblasting device 3 is inclined toward the jolting bucket 41. A certain amount of sand is gathered in the jolting bucket 41 due to sandblasting. Since the metal material being sandblasted is heavy, its inertia is greater than that of the sand. During the jolting process, the metal material will leak out from the accumulated sand due to its greater inertia, so that all surfaces of the metal material can be sandblasted.

[0026] A third bearing 47 is rotatably connected between the left side of the jolting bucket 41 and the fixing seat 1 , and a first bearing 42 is rotatably connected to the bottom of the jolting bucket 41 .

[0027] A second bearing 43 is rotatably connected to the outer wall of the disc 44 and at a position offset from the center of the circle, and a long rod is rotatably connected between the first bearing 42 and the second bearing 43; After the motor 45 is started, its output shaft drives the disc 44 to rotate. Since the disc 44 is rotationally connected to the outer wall of the motor 45, and the outer wall of the disc 44 is rotationally connected to one end of the long rod through the second bearing 43 at a position deviating from the center of the circle, and the other end of the long rod is rotationally connected to the first bearing 42 at the bottom of the jolting bucket 41, the rotation of the disc 44 will be converted into a jolting motion of the jolting bucket 41. In this process, the jolting bucket 41 swings to a certain extent around the third bearing 47 connected to the fixed seat 1 on its left side. This jolting motion causes the metal material placed in the jolting bucket 41 to continuously roll, change position and angle. Even if a certain amount of sand is gathered in the jolting bucket 41 due to sandblasting, since the sandblasted metal material itself is heavier and has a greater inertia than the sand, the metal material will leak out from the accumulated sand due to its greater inertia during the jolting process, so that all surfaces of the metal material can be sandblasted.

[0028] For example 2, please refer to Figure 1-6 Based on the first embodiment, the present invention provides a technical solution: The guide assembly 46 includes a guide ring 462 , the outer wall of which is fixedly connected to the front side of the fixing seat 1 , and the back side of the jolting bucket 41 is fixedly connected to a guide rod 461 .

[0029] The guide rod 461 is inserted into the guide ring 462, and the guide ring 462 restricts the guide rod 461 to only make circular motion. A bracket 463 is fixedly connected between the guide ring 462 and the fixing seat 1; The fixed seat 1 plays the role of stably supporting the sandblasting pot 2, the bumping mechanism 4 and the auxiliary mechanism 5. The sandblasting pot 2 is responsible for storing the sandblasting material and maintaining the internal pressure to ensure that the sandblasting material can be continuously and stably supplied to the CNC sandblasting device 3. The guide assembly 46 in the bumping mechanism 4 limits the movement trajectory and amplitude of the bumping bucket 41 through the cooperation of the guide rod 461 and the guide ring 462 to prevent its excessive shaking from affecting the stability of the equipment and the sandblasting effect.

[0030] For example 3, please refer to Figure 1-8 Based on the first and second embodiments, the present invention provides a technical solution: An auxiliary mechanism 5 is fixedly connected to the top of the fixing seat 1 away from the jolting bucket 41 on the front side.

[0031] The auxiliary mechanism 5 includes a temporary storage box 51, which is fixedly connected to the front side of the fixing base 1 at a position away from the top of the bump bucket 41. A magnetic block 54 is inserted into the top of the temporary storage box 51, a fan 55 is fixedly connected to the outer wall of the temporary storage box 51, a movable component 56 is fixedly connected to the bottom of the temporary storage box 51, and an air flow port 52 is opened at the bottom of the temporary storage box 51.

[0032] The outer wall of the temporary storage box 51 is clamped with a door panel 53 .

[0033] The movable assembly 56 includes a zigzag tube 561, which is fixedly connected to the bottom of the fan 55. A suction bin 562 is fixedly connected to the bottom of the zigzag tube 561. A guide groove 563 is fixedly connected to the inner wall of the bump bucket 41. The suction bin 562 is clamped in the guide groove 563, and the movement of the bump bucket 41 drives the movement of the suction bin 562. The fan 55 in the auxiliary mechanism 5 starts to work. The operation of the fan 55 causes the air in the temporary storage box 51 to flow. The air flows out from the air flow port 52 at the bottom of the temporary storage box 51. The magnetic block 54 plugged into the top of the temporary storage box 51 generates a magnetic field. When the sandblasting is sucked into the temporary storage box 51, the magnetic impurities such as iron filings generated by the sandblasting on the surface of the metal material will be attracted by the adsorption force of the magnetic block 54 and adsorbed around the magnetic block 54. The inner wall of the bump bucket 41 is fixedly connected with a guide groove 563. The suction bin 562 in the movable component 56 is clamped in the guide groove 563. When the bump bucket 41 is sucked by the motor 45 is driven to move, the suction bin 562 will move in the guide groove 563 with the movement of the bump bucket 41, and the zigzag tube 561 connects the fan 55 with the suction bin 562. The suction force generated by the fan 55 is transmitted to the suction bin 562 through the zigzag tube 561, so that the suction bin 562 can suck the debris and impurities generated during the sandblasting process at different heights and suck them into the temporary storage box 51. The door panel 53 clamped on the outer wall of the temporary storage box 51 is convenient for opening and cleaning the impurities collected in the temporary storage box 51 after the sandblasting operation is completed, so that the equipment can continue to carry out the next round of sandblasting operation.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
