Description

Technical Field

[0001] This utility model belongs to the field of jade polishing technology, specifically relating to a grinding and polishing device for jade carving. Background Technology

[0002] In jade carving, the grinding process removes tool marks left during the carving process, while the polishing process refines the surface luster. Currently, grinding wheels are commonly used as the basic processing equipment. By changing grinding wheels or felt polishing wheels of different grits, the process progresses from rough grinding to fine polishing. However, the processing range of grinding wheels is limited to the outer surface of the workpiece, and they cannot reach concave or hollow areas. The jade carving industry still commonly uses manual hand-held grinding sticks to locally grind and polish small areas of jade, a traditional method that is inefficient. Utility Model Content

Detailed Implementation

[0026] To better understand this utility model, the content of this utility model is further explained clearly below with reference to the embodiments and accompanying drawings. However, the protection scope of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0027] Example 1: See Figures 1-5 The purpose of this embodiment is to provide a polishing device for jade carving, including a main unit 100 and an operating handle 200 connected to the main unit 100. The main unit 100 contains a power module 101 and a drive module 102, while the operating handle 200 contains a piezoelectric transducer 201. Both the power module 101 and the piezoelectric transducer 201 are electrically connected to the drive module 102. The power module 101 is connected to an external AC220V power supply to convert AC220V into DC power and provide DC power to the drive module 102. The drive module 102 generates high-frequency AC power and outputs it to the piezoelectric transducer 201. The piezoelectric transducer 201 converts high-frequency electrical energy into mechanical vibration through the piezoelectric effect, thereby driving the polishing disc at the end of the operating handle 200 to vibrate at high frequency to achieve polishing. In this embodiment, the power module 101 and the drive module 102 are separately and independently configured, facilitating quick replacement in case of malfunction.

[0028] When polishing and grinding jade, this device needs to operate continuously for a long time, and the main unit 100 must be equipped with effective heat dissipation measures to avoid heat accumulation. Therefore, the main unit 100 housing has a side air inlet 131 on the first side panel in addition to the front and rear panels, a side air outlet 132 on the second side panel, and a bottom air outlet 133 on the bottom plate. The main unit 100 also has a cooling fan 104 and a heat sink 103. The cooling fan 104 is located at the side air inlet 131 to blow air into the main unit 100. The heat sink 103 is vertically arranged above the bottom air outlet 133 and is located between the power module 101 and the drive module 102. The side of the heat sink 103 facing the cooling fan 104 has multiple vertical heat dissipation fins. The drive module 102 is located on the side of the heat sink 103 away from the cooling fan 104, and some power components of the drive module 102 (such as switching transistors used to generate high-frequency alternating signals) are directly attached to the heat sink 103. When the heat dissipation system of the host 100 in this embodiment is working, the cooling fan 104 draws in external cold air from the side air inlet 131. The air first flows through the power module 101 to dissipate heat from the power module 101, and then blows onto the heat sink 103. Subsequently, under the obstruction of the heat sink 103 and the guidance of the heat dissipation fins, some air is directly discharged from the bottom air outlet 133, and the remaining air bypasses the heat sink 103 and is discharged from the side air outlet 132, thereby achieving heat dissipation for the heat sink 103 and the drive module 102.

[0029] The drive module 102 is also electrically connected to a foot switch 300. The drive module 102 outputs high-frequency current to the piezoelectric transducer 201 only when the foot switch 300 is closed.

[0030] The front and rear panels of the main unit 100 are also equipped with a power interface 121, a power switch 113, a handle interface 112, and a switch interface 122. The power interface 121 is used to insert a power cord for connection to an external AC220V power supply; the power switch 113 is connected in series between the power interface 121 and the power module 101 to control the on / off of the AC220V power supply; the handle interface 112 is electrically connected between the piezoelectric transducer 201 and the drive module 102, enabling the pluggable connection of the operating handle 200; the switch interface 122 is electrically connected between the foot switch 300 and the drive module 102, enabling the pluggable connection of the foot switch 300.

[0031] The drive module 102 is also electrically connected to a voltage regulator module 141, or the drive module 102 has a voltage regulator module 141 electrically connected to it. The voltage regulator module 141 provides DC power to the cooling fan 104. The cooling fan 104 is in contact with the heat sink 103. Specifically, the voltage regulator module 141 includes a 7812CT Zener transistor with an output voltage of 12V.

[0032] The front panel of the host 100 is also provided with an instrument panel 111, which is used to display the working status of the host 100. In this embodiment, the instrument panel 111 is an ammeter.

[0033] In one possible implementation, a partial circuit schematic of the drive module 102 is shown below. Figure 6 As shown in the diagram. U1 is a three-terminal voltage regulator LM317, U2 is a transformer, and U3 is a piezoelectric transducer 201. Transistor Q1 is an SS8050, and transistor Q2 is a BU406. Transistor BU406 is a switching transistor used to generate high-frequency alternating signals. Both the three-terminal voltage regulator LM317 and transistor BU406 are mounted on heatsink 103. Figure 6 The diagram shows a self-excited oscillation circuit. U1 provides a stable operating voltage for the circuit, Q1 automatically adjusts the output power, and Q2 and surrounding components form an oscillation circuit. The high-frequency oscillation current is output from terminals 3 and 4 of U2, driving U3 to work.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
