Description

Technical Field

[0001] This utility model belongs to the field of jewelry processing technology, specifically relating to a sandblasting device for gold jewelry processing. Background Technology

[0002] Jewelry refers to ornaments made primarily of gold. Gold jewelry can be categorized into two types based on its gold content: pure gold and karat gold. To overcome the drawbacks of gold, such as high price, low hardness, limited color, susceptibility to wear, and lack of intricate patterns, other metallic elements are typically added to pure gold to increase its hardness, alter its color, and lower its melting point. This results in gold alloy jewelry with varying purity and significantly different gold contents.

[0003] Existing sandblasting devices for gold jewelry processing are driven by threaded rods to secure gold bracelets. However, during use, the threaded rods are prone to loosening and instability. Furthermore, sandblasting the gold bracelets is done manually, which can result in excessive or insufficient force, thus affecting the sandblasting accuracy. Summary of the Invention

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. Example

[0017] Please see Figure 1-5 The present invention provides the following technical solution: a sandblasting device for gold jewelry processing, including a base 1, a collection box 2 fixedly installed in the middle of the upper part of the base 1, a support frame 3 provided above the collection box 2, the two ends of the support frame 3 fixedly connected to the base 1, a grinding motor 4 installed in the middle of the lower part of the support frame 3, a grinding wheel 5 fixedly connected to the output end of the grinding motor 4, a metal chip blocking cover 6 installed on one side of the grinding motor 4, a clamping assembly 7 installed at one end of the upper part of the base 1, and the support frame 3 and the grinding motor 4 connected by a drive assembly 8; The clamping assembly 7 includes a clamping seat 71, which is located at one end above the base 1. A DC motor 72 is fixedly installed above the clamping seat 71. A bidirectional trapezoidal lead screw 73 is fixedly connected to the output end of the DC motor 72. The bidirectional trapezoidal lead screw 73 and the clamping seat 71 are rotatably connected by bearings. A square slider 74 is symmetrically connected to the surface of the bidirectional trapezoidal lead screw 73 and threadedly connected to it. The square slider 74 is in contact with and slidably connected to the clamping seat 71. A pressure sensor 75 is installed at one end of the square slider 74 through a fixing assembly 76. An arc-shaped clamping plate 77 is fixedly connected to one end of the pressure sensor 75.

[0018] Specifically, a rubber protective pad 78 is fixedly connected to one side of the arc-shaped clamping plate 77.

[0019] By adopting the above technical solution, a DC motor 72 is driven, which drives a bidirectional trapezoidal lead screw 73 to rotate. The rotation of the bidirectional trapezoidal lead screw 73 will drive a square slider 74 to move. The movement of the square slider 74 will drive an arc-shaped clamping plate 77 to move, which cooperates with the rubber protective pad 78 to fix the gold bracelet. During fixing, the pressure sensor 75 can monitor the clamping force, so that the clamping force is controlled within a reasonable clamping range to prevent excessive force from causing damage.

[0020] Specifically, a geared motor 79 is fixedly connected to one side of the clamping base 71, and the lower part of the geared motor 79 is fixedly connected to the base 1.

[0021] By adopting the above technical solution and setting the geared motor 79, the gold bracelet can be rotated easily.

[0022] Specifically, the fixing component 76 includes a fixing seat 761, which is fixedly connected to one end of the square slider 74. A square plug 762 is tightly inserted into the lower part of the fixing seat 761. The lower part of the square plug 762 is fixedly connected to the pressure sensor 75. A fixing screw 763 is threadedly connected to one end of the fixing seat 761. A cylindrical fixing block 764 is fixedly connected to one end of the fixing screw 763. The cylindrical fixing block 764 and the fixing seat 761 are in contact and slidably connected.

[0023] By adopting the above technical solution, rotating the fixing screw 763 causes the cylindrical fixing block 764 to move, separating it from the square insert 762. Then, the pressure sensor 75 can be removed for inspection and maintenance by separating the square insert 762 from the fixing seat 761.

[0024] In this embodiment, during use: the DC motor 72 is driven, which in turn drives the bidirectional trapezoidal lead screw 73 to rotate. The rotation of the bidirectional trapezoidal lead screw 73 causes the square slider 74 to move. The movement of the square slider 74 causes the arc-shaped clamping plate 77 to move, cooperating with the rubber protective pad 78 to fix the gold bracelet. During fixing, the pressure sensor 75 can monitor the clamping force, ensuring that the clamping force is controlled within a reasonable range to prevent excessive force from causing damage. This allows the device to stably fix the gold bracelet during use. Example

[0025] The difference between this embodiment and embodiment 1 is that, specifically, the drive assembly 8 includes an electric telescopic rod 81, which is fixedly connected to the middle of the support frame 3, and a connecting seat 82 is fixedly connected to the lower part of the electric telescopic rod 81.

[0026] By adopting the above technical solution, and using the electric telescopic rod 81 to drive the manual operation, the accuracy of sandblasting can be improved.

[0027] Specifically, a mounting plate 83 is installed on one side of the connector 82, and one side of the mounting plate 83 is fixedly connected to the metal debris blocking cover 6. A mounting screw 84 is inserted into one end of the mounting plate 83, and the mounting screw 84 is threadedly connected to the connector 82.

[0028] By adopting the above technical solution, the mounting plate 83 and the connecting seat 82 can be easily separated by unscrewing the mounting screw 84, which facilitates the disassembly and cleaning of the metal debris blocking cover 6.

[0029] Specifically, connecting plates 85 are fixedly connected to both sides of the connecting seat 82, and a stabilizing slide rod 86 is fixedly connected to the top of the connecting plate 85. The stabilizing slide rod 86 and the support frame 3 are in contact and slidably connected.

[0030] By adopting the above technical solution, the stabilizing slide bar 86 can be raised and lowered stably.

[0031] In this embodiment, the sandblasting accuracy can be improved by using the electric telescopic rod 81 to drive the manual drive, and the stable slide rod 86 can be raised and lowered stably, so that the device can stably drive the sandblasting during use.

[0032] The working principle and usage process of this utility model: This utility model is used for processing gold bracelets and performing sandblasting. The gold bracelet is clamped and fixed by the clamping component 7. Then, the grinding motor 4 is started to drive the grinding wheel 5 to rotate. Then, the grinding wheel 5 is driven to move down by the driving component 8 to perform sandblasting.

[0033] When the clamping assembly 7 is in use, the DC motor 72 is driven, which in turn drives the bidirectional trapezoidal lead screw 73 to rotate. The rotation of the bidirectional trapezoidal lead screw 73 causes the square slider 74 to move, which in turn causes the arc-shaped clamping plate 77 to move and cooperate with the rubber protective pad 78 to fix the gold bracelet. During fixing, the pressure sensor 75 can monitor the clamping force to keep it within a reasonable clamping range and prevent excessive force from causing damage. This allows the device to stably fix the gold bracelet during use.

[0034] When the drive assembly 8 is in use, it is driven manually by the electric telescopic rod 81, which can improve the accuracy of sanding. The stabilizing slide rod 86 can be raised and lowered stably, so that the device can drive sanding stably during use.

[0035] 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.
