Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting treatment of castings, and in particular to a sandblasting machine for processing castings. Background Technology

[0002] Sandblasting machines grind, clean, and improve material surfaces by spraying abrasive particles at high speed. The basic principle is to use a high-pressure airflow to accelerate abrasive materials (such as quartz sand or glass beads) and propel them onto the workpiece surface. The collision and friction between the particles and the workpiece surface remove oxide layers, stains, coatings, etc., and can also alter the surface morphology to some extent, increasing surface roughness and providing a good foundation for subsequent processing or coating adhesion.

[0003] In the prior art, the sandblasting machine for processing castings disclosed in CN220128536U includes a base, a cylinder, and a translation mechanism. The translation mechanism includes a rotating seat, a second lead screw, a slide rod, and a movable seat. The rotating seat is fixedly installed at both ends of the movable slot, the second lead screw is rotatably installed in the middle of the rotating seats at both ends, the slide rod is fixedly installed in the middle of the rotating seats at both ends, and the movable seat is threadedly connected to the second lead screw and slidably connected to the slide rod. A nozzle is provided on one side of the movable seat inside the cylinder, and a rotation drive mechanism is provided at both ends of the cylinder. This design can perform reciprocating liquid sandblasting operations along the axis of long shaft castings, significantly increasing the sandblasting operation area. It can also adapt to long shaft castings of different lengths. The use of liquid sandblasting can significantly reduce dust dispersion, thus facilitating indoor processing operations and reducing environmental pollution.

[0004] The application can adapt to long shaft castings of different lengths when in use, and the liquid sandblasting method reduces dust and is environmentally friendly while expanding the sandblasting operation area. However, when in use, the two ends of the long shaft are clamped, which prevents the ends from being sandblasted by the sandblasting mechanism. As a result, a second operation is required to sandblast the ends of the long shaft casting, which affects the sandblasting effect of the long shaft casting. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sandblasting machine for processing castings, so as to solve the technical problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A sandblasting machine for processing castings includes a sandblasting chamber, a closed door, and a shaft-shaped casting. The bottom of the sandblasting chamber has a sliding groove, and two columns are slidably connected in the sliding groove. The top of each column is connected to a positioning ring, and the shaft-shaped casting is placed in the two positioning rings. The bottom of the sandblasting chamber also has a moving groove, and a mounting plate is slidably connected in the moving groove. A reciprocating component is provided at the end of the mounting plate, and a rotating component is provided on the top side of the mounting plate.

[0008] The rotating component includes an electric telescopic joint, a clamping plate, a rotating shaft, and a motor. The electric telescopic joint is fixedly connected to the top side of the mounting plate, and the telescopic end of the electric telescopic joint faces the shaft-shaped casting. The clamping plate is fixedly installed on the outer periphery of the telescopic end of the electric telescopic joint. The rotating shaft is rotatably connected inside the clamping plate. The motor is fixedly connected to the outer side of the clamping plate. The output end of the drive motor is drivenly connected to the end of the rotating shaft.

[0009] In a preferred embodiment, the present invention can be further configured such that: a gap is left between the circumferential side of the rotating shaft and the telescopic end of the electric telescopic joint, and a number of anti-slip protrusions are fixedly connected to the outer circumferential side of the rotating shaft.

[0010] In a preferred embodiment, the present invention can be further configured such that: the reciprocating component includes a second motor, the second motor is fixedly installed at the inner end of the moving groove, the output end of the second motor is connected to a drive rod, the end of the drive rod is hinged to a connecting rod, and the end of the connecting rod is hinged to the end of the mounting plate.

[0011] In a preferred embodiment, the present invention can be further configured such that: a plurality of sliding balls are rotatably connected within each of the two positioning rings, and the outer side of the sliding balls is in contact with the outer periphery of the shaft casting.

[0012] In a preferred embodiment, the present invention can be further configured such that: an adjusting screw is rotatably connected to the inner end sidewall of the slide groove, the end of the adjusting screw passes through the two columns, and the adjusting screw is threadedly connected to the two columns.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. The sandblasting machine for processing castings can drive the rotating part to move through the reciprocating part during use, so that the rotating shaft fits into the shaft-shaped casting, thereby driving the shaft-shaped casting to rotate and reciprocate at the same time, so that the shaft-shaped casting can be sandblasted in all directions, avoiding dead corners and the end of the shaft-shaped casting being blocked, which would require secondary sandblasting at the end of the shaft-shaped casting, thus reducing the sandblasting efficiency of the shaft-shaped casting.

[0016] 2. A sandblasting machine for processing castings, wherein a motor drives a drive rod to rotate, and the two ends of the connecting rod are respectively hinged to the end of the drive rod and the end of the mounting plate. Therefore, when the drive rod rotates, it drives the mounting plate to slide back and forth in the moving groove through the connecting rod. The back and forth sliding of the mounting plate drives the reciprocating motion of the electric telescopic joint, and finally drives the reciprocating motion of the rotating shaft, so as to drive the shaft-shaped casting to rotate and move back and forth, thereby achieving the effect of sandblasting the shaft-shaped casting in all directions.

[0017] 3. The sandblasting machine for processing castings is equipped with a sliding ball to reduce the friction between the shaft-shaped casting and the positioning ring, thereby facilitating the rotation and movement of the shaft-shaped casting within the positioning ring and preventing excessive friction from affecting the rotation and movement of the shaft-shaped casting driven by the rotating shaft.

[0018] 4. The sandblasting machine for processing castings is equipped with an adjusting screw that can be manually rotated. The threads at both ends of the adjusting screw are set in opposite directions, so as to drive the two columns to move in opposite directions, so as to place shaft castings of different lengths for sandblasting.

[0019] 5. In this sandblasting machine for processing castings, gaps are left between the two ends of the shaft-shaped casting and the end sidewalls of the closed door and the sandblasting chamber, respectively, so as to provide movement space for the shaft-shaped casting when it moves, and to avoid the shaft-shaped casting from hitting the end sidewalls of the closed door and the sandblasting chamber, thereby causing damage to the closed door and the sandblasting chamber.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example: Refer to Figures 1-4 This utility model discloses a sandblasting machine for processing castings, including a sandblasting chamber 1, a closed door 2, and a shaft-shaped casting 3. The bottom of the sandblasting chamber 1 is provided with a sliding groove 4, and two columns 5 are slidably connected in the sliding groove 4. The top of the columns 5 is connected with a positioning ring 6. The shaft-shaped casting 3 is placed in the two positioning rings 6. The bottom of the sandblasting chamber 1 is also provided with a moving groove 7, and an installation plate 8 is slidably connected in the moving groove 7. The end of the installation plate 8 is provided with a reciprocating part 9, and the top side of the installation plate 8 is provided with a rotating part 10.

[0028] The rotating component 10 includes an electric telescopic joint 11, a clamping plate 12, a rotating shaft 13, and a motor 14. The electric telescopic joint 11 is fixedly connected to the top side of the mounting plate 8, and the telescopic end of the electric telescopic joint 11 faces the shaft-shaped casting 3. The clamping plate 12 is fixedly installed on the outer periphery of the telescopic end of the electric telescopic joint 11. The rotating shaft 13 is rotatably connected inside the clamping plate 12. The motor 14 is fixedly connected to the outer side of the clamping plate 12, and the output end of the motor 14 is drivenly connected to the end of the rotating shaft 13.

[0029] In this embodiment, when in use, the closed door 2 is opened manually, and then the end of the shaft casting 3 is inserted into the positioning ring 6 closest to the closed door 2. Then, the shaft casting 3 is pushed until it is inserted into the second positioning ring 6 and pushed inward a certain distance. Then, the closed door 2 is closed and sandblasting is performed.

[0030] Sandblasting guns are installed at the top of the sandblasting chamber 1 and in the direction opposite to the electric telescopic joint 11. The number of sandblasting guns is determined by the actual working conditions, and the number of sandblasting guns is not less than two.

[0031] When the sandblasting gun is started, the electric telescopic joint 11 also needs to be started, so that the electric telescopic joint 11 drives the clamping plate 12 and the rotating shaft 13 to adhere to the shaft-shaped casting 3 until the rotating shaft 13 is in contact with the shaft-shaped casting 3 and a certain force is applied. Then the motor 14 is started, so that the motor 14 drives the rotating shaft 13 to rotate. The friction generated when the rotating shaft 13 is in contact with the shaft-shaped casting 3 will cause the shaft-shaped casting 3 to rotate through the rotating shaft 13, so that the sandblasting gun can perform multi-directional sandblasting treatment on the shaft-shaped casting 3.

[0032] The reciprocating component 9 is used to drive the mounting plate 8 to slide back and forth in the moving groove 7. When the mounting plate 8 moves back and forth in the moving groove 7, it will also drive the rotating shaft 13 to move. Since the rotating shaft 13 is in a state of contact with the shaft casting 3, the mounting plate 8 will drive the rotating shaft 13 to move back and forth, thereby exposing the part of the shaft casting 3 that was covered by the positioning ring 6. This allows for all-round sandblasting of the shaft casting 3, thus avoiding dead corners during sandblasting.

[0033] It should be noted that the motor 14 and the electric expansion joint 11 in this application need to be fitted with corresponding housings in order to protect the electric expansion joint 11 and the motor 14.

[0034] In a further preferred embodiment of this utility model, such as Figure 3 As shown, there is a gap between the circumferential side of the rotating shaft 13 and the telescopic end of the electric telescopic joint 11, and a number of anti-slip protrusions 15 are fixedly connected to the outer circumferential side of the rotating shaft 13.

[0035] In this embodiment, a gap is left between the circumferential side of the rotating shaft 13 and the telescopic end of the electric telescopic joint 11, and an anti-slip protrusion 15 is provided on the outer circumferential side of the rotating shaft 13 to prevent friction between the rotating shaft 13 and the telescopic end of the electric telescopic joint 11 when the rotating shaft 13 rotates, thereby preventing the end of the electric telescopic joint 11 from being damaged by friction. The anti-slip protrusion 15 is provided to improve the surface roughness of the rotating shaft 13, thereby increasing the friction between the rotating shaft 13 and the shaft casting 3, so that the rotating shaft 13 can drive the shaft casting 3 to rotate and move.

[0036] In a further preferred embodiment of this utility model, such as Figure 2As shown, the reciprocating component 9 includes a second motor 16, which is fixedly installed at the inner end of the moving groove 7. The output end of the second motor 16 is connected to a drive rod 17, and the end of the drive rod 17 is hinged to a connecting rod 18. The end of the connecting rod 18 is hinged to the end of the mounting plate 8.

[0037] In this embodiment, motor 16 drives drive rod 17 to rotate. The two ends of connecting rod 18 are hinged to the ends of drive rod 17 and mounting plate 8, respectively. Therefore, when drive rod 17 rotates, it drives mounting plate 8 to slide back and forth in moving groove 7 through connecting rod 18. The back and forth sliding of mounting plate 8 drives electric telescopic joint 11 to reciprocate, and finally drives rotating shaft 13 to reciprocate, so as to drive shaft casting 3 to rotate and reciprocate, thereby achieving the effect of all-round sandblasting of shaft casting 3. A protective shell needs to be installed on the outside of motor 16 to protect motor 16.

[0038] In a further preferred embodiment of this utility model, such as Figure 4 As shown, a number of sliding balls 19 are rotatably connected inside each of the two positioning rings 6, and the outer side of the sliding balls 19 is in contact with the outer periphery of the shaft casting 3.

[0039] In this embodiment, the sliding ball 19 is provided to reduce the friction between the shaft casting 3 and the positioning ring 6, thereby facilitating the rotation and movement of the shaft casting 3 within the positioning ring 6 and preventing excessive friction from affecting the rotation and movement of the shaft casting 3 driven by the rotating shaft 13.

[0040] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, an adjusting screw 20 is rotatably connected to the inner end sidewall of the slide groove 4. The end of the adjusting screw 20 passes through the two columns 5, and the adjusting screw 20 is threadedly connected to the two columns 5.

[0041] In this embodiment, the adjusting screw 20 can be manually rotated. The threads at both ends of the adjusting screw 20 are set in opposite directions, so as to drive the two columns 5 to move in opposite directions, so as to place shaft castings 3 of different lengths for sandblasting.

[0042] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, there is a gap between the end of the shaft casting 3 away from the closed door 2 and the end side wall of the sandblasting chamber 1, and there is a gap between the end of the shaft casting 3 near the closed door 2 and the side surface of the closed door 2.

[0043] In this embodiment, gaps are left between the two ends of the shaft-shaped casting 3 and the end sidewalls of the closed door 2 and the sandblasting chamber 1, respectively, so as to provide movement space for the shaft-shaped casting 3 when it moves, and to avoid the shaft-shaped casting 3 from hitting the end sidewalls of the closed door 2 and the sandblasting chamber 1, thereby causing damage to the closed door 2 and the sandblasting chamber 1.

[0044] In this embodiment, it is important to know that a control panel is installed outside the sandblasting chamber 1 and is connected to the motor 14, the motor 2 16 and the electric telescopic joint 11 to facilitate the sandblasting of the shaft casting 3.

[0045] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
