Description

Technical Field

[0001] This utility model relates to the field of sandblasting equipment technology, and in particular to a sandblasting treatment device for motorcycle parts. Background Technology

[0002] In the manufacturing process of motorcycle parts, sandblasting is an important surface treatment process that can effectively remove impurities such as rust, scale, and oil from the surface of the parts. At the same time, it can significantly improve the adhesion and bonding strength of subsequent coatings by roughening the surface.

[0003] Chinese patent CN210998236U discloses a sandblasting device for automotive parts, including a machine body. A collection box is slidably connected to the bottom of the machine body. Two fixed pulleys are arranged on the inner side wall of the machine body, and a conveyor belt is arranged between the two fixed pulleys. A support rod is fixedly connected to the upper surface of the collection box, and a chassis is fixedly connected to the upper end of the support rod. An annular groove is formed on the upper surface of the chassis, and a sliding block is slidably connected inside the annular groove. A base plate is fixedly connected to the upper surface of the sliding block. Multiple electromagnets are evenly arranged on the upper surface of the base plate, and the main body of the parts is arranged between the multiple electromagnets. A mounting frame is provided at the top of the machine body. This device can process multiple parts at once, achieving high efficiency and speed. It has a reasonable design, incorporates a vibration and shaking structure, and has an ideal fine sand recovery device, preventing fine sand from accumulating on the surface.

[0004] When this device performs sandblasting on parts, the parts are of different shapes, and uneven processing is very likely to occur during the blasting process. Complex curved surfaces, deep holes, grooves and other special structural areas are difficult to be fully covered by the sandblasting medium, forming processing dead corners. As a result, impurities remain in these areas, and the surface roughness cannot meet the process requirements. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-5 As shown, a sandblasting device for motorcycle parts includes an abrasive box 1. Four support legs 2 are symmetrically fixed at the four corners of the bottom of the abrasive box 1. A conical disc seat 3 is fixedly connected to the top of the abrasive box 1. An intermediate storage plate 4 is fixedly connected to the middle of the inner cavity of the conical disc seat 3. Multiple feeding slots 41 are equidistantly arranged in a ring array at the connection between the intermediate storage plate 4 and the inner cavity of the conical disc seat 3. A reciprocating component 5 is arranged through the middle of the top of the intermediate storage plate 4. A material collection component 6 is arranged at the bottom of the inner cavity of the abrasive box 1. Multiple nozzle fixing components 7 are clamped at the upper port of the conical disc seat 3.

[0025] In practical use, the nozzles of the sandblasting machine are clamped at the upper port of the conical disc seat 3 by the nozzle fixing component 7. The reciprocating component 5 in the abrasive box 1 causes the motorcycle parts to circulate up and down repeatedly. This, combined with the sandblasting machine, allows for full-angle spraying of the motorcycle parts that are rolling up and down in the abrasive box 1 without dead angles, eliminating the blind spots that exist in traditional fixed-position sandblasting. By setting up the material collection component 6 to circulate and transport the liquid sand abrasive mixture sprayed by the sandblasting machine, the liquid sand abrasive mixture is recycled, which greatly reduces the loss of the liquid sand abrasive mixture.

[0026] Specifically, the reciprocating assembly 5 includes a barrel 51 and a roller base 58. The barrel 51 is fixedly installed at the top center of the intermediate storage plate 4, and the bottom end of the barrel 51 is installed at the bottom end of the inner cavity of the abrasive box 1. The roller base 58 is fixedly installed on the outer side of the bottom end of the inner cavity of the conical disc seat 3 away from the center.

[0027] Multiple feed inlets 52 are arranged in a ring array on the outer surface of the material cylinder 51 near the bottom of the slope of the roller base 58, and multiple liquid discharge holes 59 are arranged in a ring array at the bottom of the slope of the roller base 58.

[0028] A servo motor 53 is fixedly connected to the middle of the bottom end of the material cylinder 51. A rotating rod 54 is vertically rotatably installed in the middle of the inner cavity of the material cylinder 51. The output shaft of the servo motor 53 is fixedly connected to the rotating rod 54 through a coupling. An auger disc 55 adapted to the inner cavity surface of the material cylinder 51 is coaxially fixedly connected to the outer surface of the rotating rod 54. An L-shaped connecting plate 56 is fixedly connected to the top end of the rotating rod 54. A cleaning component 57 that contacts the top surface of the intermediate temporary storage plate 4 is fixedly connected to the end of the L-shaped connecting plate 56 away from the rotating rod 54.

[0029] After the motorcycle parts are poured into the conical disc seat 3, the servo motor 53 is started. The output shaft of the servo motor 53 drives the rotating rod 54 to rotate the sweeping part 57. The centrifugal force generated by the rotation of the sweeping part 57 moves the motorcycle parts stacked on the intermediate temporary plate 4, so that the motorcycle parts fall into the lower side of the inner cavity of the conical disc seat 3 through the feeding chute 41.

[0030] After the motorcycle parts fall into the lower side of the inner cavity of the conical disc seat 3, they pass through the inclined slope of the roller base 58 and enter the material cylinder 51 through the feed port 52. When the servo motor 53 drives the rotating rod 54, it drives the auger disc 55 to rotate forward. The forward rotation of the auger disc 55 causes the motorcycle parts that have fallen into the material cylinder 51 to be conveyed upward. After the parts are conveyed to the designated position, they fall onto the intermediate temporary plate 4 through the upper port of the material cylinder 51. This achieves the purpose of reciprocating loading and unloading.

[0031] The nozzle of the sandblasting machine performs sandblasting on the motorcycle parts on the intermediate temporary storage plate 4.

[0032] The liquid abrasive mixture sprayed from the sandblasting machine flows into the abrasive box 1 through multiple liquid discharge holes 59 for further processing.

[0033] Furthermore, the material collection assembly 6 includes a material collection hopper 61 and a water pump 62. The material collection hopper 61 is fixedly connected to the lower side of the inner cavity of the abrasive box 1, and the water pump 62 is fixedly connected to the bottom of the abrasive box 1. The output end of the water pump 62 extends to the lower side of the middle of the inner cavity of the material collection hopper 61, and the output end of the water pump 62 is fixedly connected to a conveying pipe 621 through a flange.

[0034] After the liquid abrasive mixture enters the abrasive box 1, the liquid abrasive mixture stored in the abrasive box 1 is transported to the outside for further processing through the feed port 52.

[0035] Furthermore, the nozzle fixing assembly 7 includes a connecting plate 71 and a sliding clamping plate 77. A fixing clamping plate 74 is fixedly connected to the bottom side of the connecting plate 71 away from the middle. The sliding clamping plate 77 is slidably arranged on the lower side of the bottom of the connecting plate 71. The connecting plate 71 is clamped to the upper port of the conical disc seat 3 by the sliding clamping plate 77 and the fixing clamping plate 74. An insertion hole 72 is provided through the top side of the connecting plate 71 away from the fixing clamping plate 74.

[0036] A guide groove 73 is provided through one side of the top of the connecting plate 71 near the middle. A guide rod 75 is fixedly connected in the inner cavity of the guide groove 73. A push handle 76 is slidably connected to the outer surface of the guide rod 75. The top of the sliding clamp 77 is fixedly connected to the bottom of the push handle 76. A spring 78 is sleeved on the outer surface of the guide rod 75. The two ends of the spring 78 are respectively held between the push handle 76 and the end of the inner cavity of the guide groove 73 away from the fixed clamp 74.

[0037] The nozzle of the sandblasting machine can be adjusted at multiple angles through the gooseneck tube. The gooseneck tube is inserted into the insertion hole 72 for limiting. The tension of the spring 78 pushes the sliding clamp 77 and the fixed clamp 74 closer together, thereby making the fixed clamp 74 and the sliding clamp 77 clamp and fix the upper wall of the conical disc seat 3.

[0038] It should be noted that the specific installation method, circuit connection method, and control method of the servo motor 53 and water pump 62 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
