Description

Technical Field

[0001] This utility model relates to the field of sandblasting technology, specifically to an auxiliary device for sandblasting mechanical parts. Background Technology

[0002] In the field of mechanical parts processing, sandblasting is a key process for improving the surface roughness of parts and removing oxide scale and impurities. It is widely used in the pretreatment and surface strengthening of various parts and directly affects the subsequent assembly accuracy and service life of parts.

[0003] Most sandblasting machines on the market today are equipped with a perforated plate to support parts and guide sand. However, when processing sheet metal or parts with a high degree of flatness, the limitations of this type of device become increasingly apparent: because the bottom surface of the part is in close contact with the surface of the perforated plate, there is almost no gap between them for operation; at the same time, the impact force of the sand during sandblasting is relatively large, and workers need to wear heavy abrasion-resistant gloves for protection, which greatly reduces hand dexterity.

[0004] In practice, when parts need to be flipped to ensure all-around sandblasting, the heavy gloves lack sufficient friction against the part surface, easily causing slippage and making it difficult to stably hold the part for flipping. After sandblasting, because the part is tightly fitted to the perforated plate without gaps, workers lack the space to apply force and can only painstakingly pry the edges to remove it. This method not only severely slows down work efficiency but may also scratch the part surface during prying or damage the gloves due to edge friction, increasing operating costs.

[0005] Therefore, an auxiliary device for sandblasting mechanical parts is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an auxiliary device for sandblasting mechanical parts to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for sandblasting of mechanical parts, comprising a frame, a collection box for collecting sandblasting material is installed at the bottom of the frame, a drive shaft is rotatably connected to the inner center of the collection box, and multiple turntables are installed on the drive shaft, the turntables being non-axial with the drive shaft;

[0008] A perforated plate is installed on the top of the collection box, and a lifting shell is slidably connected to the middle of the perforated plate. The lifting shell is located directly above the turntable.

[0009] Preferably, the perforated plate has a through groove in the middle, and multiple limiting rods are evenly installed on the inner side of the through groove.

[0010] Preferably, the lifting shell is provided with multiple limiting grooves evenly distributed on it, and the limiting rod is slidably connected to the inside of the limiting groove.

[0011] Preferably, a drive motor for driving the transmission shaft to rotate is installed on one side of the bottom of the frame.

[0012] Preferably, an observation window made of tempered glass is installed above the front surface of the frame to facilitate the sandblasting process.

[0013] Preferably, the frame has symmetrical through holes on the lower front surface to facilitate the passage of workers' hands, and a door is installed on one side of the frame.

[0014] Preferably, the collection box is a quadrangular prism with an outlet at the bottom for discharging sand.

[0015] Compared with existing technologies, the advantages of this invention are as follows: By using a non-coaxial turntable in conjunction with the lifting housing, when the drive motor rotates the transmission shaft, the turntable can push the lifting housing upwards stably, creating an operating space between the parts and the perforated plate. This allows for easy flipping or removal of parts without the need for laborious edge-picking, preventing scratches on parts and damage to gloves, and significantly reducing operation time. Furthermore, when the lifting housing is not raised, it is flush with the perforated plate, forming a flat bearing surface, ensuring stable placement of parts without displacement, avoiding excessive or incomplete sandblasting, and guaranteeing uniform surface treatment.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-5 This utility model provides a technical solution: an auxiliary device for sandblasting mechanical parts, including a frame 1. A collection box 6 for collecting sand scattered during the sandblasting process is fixedly installed at the bottom of the frame 1. A transmission shaft 8 is rotatably connected to the inner middle of the collection box 6 via a bearing. Multiple turntables 9 are installed on the outer side of the transmission shaft 8. The turntables 9 are not coaxial with the transmission shaft 8. This non-coaxial structure can drive the upper parts to move up and down when the transmission shaft 8 rotates. A perforated plate 5 is detachably installed on the top of the collection box 6. A lifting shell 10 is slidably connected to the middle of the perforated plate 5 in the vertical direction. The lifting shell 10 is located directly above the turntables 9. The rotation of the turntables 9 can realize the up and down movement of the lifting shell 10, thereby driving the internal parts to separate from the perforated plate 5, making it easier to pick up the parts.

[0024] like Figure 4 and Figure 5 As shown: The perforated plate 5 has a through groove 13 in the middle for the lifting shell 10 to pass through and slide. Multiple limiting rods 11 are evenly installed on the inner side wall of the through groove 13. Multiple limiting grooves 12 that are adapted to the limiting rods 11 are evenly opened on the outer side wall of the lifting shell 10. The limiting rods 11 are slidably connected to the inside of the limiting grooves 12. The sliding cooperation structure of the two can make the lifting movement of the lifting shell 10 smoother, and at the same time further enhance the stability of the lifting shell 10 when it moves, and prevent the parts from shaking.

[0025] like Figure 2 As shown: A drive motor 7 for driving the transmission shaft 8 to rotate is fixedly installed on one side bottom of the frame 1 via a motor bracket. The output shaft of the drive motor 7 is fixedly connected to one end of the transmission shaft 8 via a coupling, which can stably transmit power to the transmission shaft 8, providing a power source for the continuous rotation of the transmission shaft 8, and ensuring that the lifting shell 10 can perform lifting movements.

[0026] like Figure 1 As shown: An observation window 3 is embedded above the front surface of the frame 1, which allows workers to observe the internal sandblasting process in real time. The observation window 3 is made of tempered glass, which has the advantages of high temperature resistance, impact resistance and good light transmission. It can withstand the impact of sand and changes in ambient temperature during the sandblasting process, and allows workers to clearly see the sandblasting progress and effect of the parts, so as to make it convenient to adjust the operating parameters in a timely manner.

[0027] like Figure 1 As shown: Symmetrical through holes 4 are provided on the lower front surface of the frame 1 to facilitate workers' hands to reach in and operate the sandblasting tools. A door 2 for picking up and putting in parts is connected to one side of the frame 1 by a hinge. When the door 2 is closed, a relatively closed sandblasting space is formed inside the frame 1 to reduce sand leakage. When it is open, mechanical parts to be processed or already processed can be quickly put in or taken out.

[0028] like Figure 2 and Figure 3As shown: The collection box 6 has a quadrangular prism structure, which has the advantages of large volume, strong placement stability, and easy installation of internal drive shaft 8 and turntable 9; an outlet for discharging collected sand is provided at the center of its bottom, and a valve can be installed at the outlet. Workers can control the valve to discharge the collected sand in a concentrated manner, realizing the recycling and reuse of sand and reducing the cost of sandblasting.

[0029] Working principle: First, open the door 2 on one side of the frame 1, place the part to be sandblasted in the middle of the perforated plate 5, and close the door 2 to create a relatively enclosed space inside the frame 1, reducing sand leakage during the sandblasting process. The worker's hand reaches through the through hole 4 at the bottom of the front surface of the frame 1 to hold the sandblasting tool and perform sandblasting operations on the part. At the same time, the worker can observe the sandblasting progress and surface treatment effect of the part in real time through the tempered glass observation window 3 above the front surface of the frame 1, so as to adjust the sandblasting parameters in a timely manner.

[0030] When parts need to be flipped or removed after sandblasting, the drive motor 7 on one side of the bottom of the frame 1 is activated. The drive motor 7 outputs power to rotate the transmission shaft 8 in the middle of the inner side of the collection box 6. Because the turntable 9 installed on the transmission shaft 8 is not coaxial with the transmission shaft 8, the turntable 9 generates an upward pushing force when it rotates with the transmission shaft 8, which acts on the bottom of the lifting shell 10 located directly above it. At this time, the lifting shell 10 slides and engages with the limiting rod 11 through the limiting groove 12, and rises stably in the vertical direction, simultaneously lifting the sheet metal parts, so that a certain operating space is formed between the bottom of the parts and the upper surface of the perforated plate 5.

[0031] Using the space formed between the part and the perforated plate 5, workers can easily flip the part without having to painstakingly pry off its edges. If the sandblasting operation is complete, the part can be easily removed directly through this space, avoiding the difficulty of handling the part due to it sticking to the perforated plate 5. Sand that falls during the sandblasting process will fall into the collection box 6 below through the mesh of the perforated plate 5. After the operation is completed, the sand can be discharged through the outlet at the bottom of the collection box 6, realizing the recycling and reuse of sand.

[0032] When the lifting shell 10 is not raised and is flush with the surface of the perforated plate 5, a complete and flat bearing surface can be formed. The parts to be sandblasted can be placed stably without tilting or shaking due to the height difference between the two. This ensures the stability of the part position during the sandblasting process, avoids local over-sandblasting or omission due to part displacement, ensures the uniformity of the part surface treatment, and meets the requirements of the sandblasting process for part positioning accuracy.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
