Description

Technical Field

[0001] This utility model relates to the field of carving tools, specifically to a processing device for gold lacquer openwork carving. Background Technology

[0002] Gold lacquer openwork carving uses wood as the base material. Pure natural raw lacquer is boiled at high temperature and then repeatedly rubbed onto the surface of the mahogany. After more than 20 polishing and drying, a black base lacquer is formed as the background for carving. Fine and intricate patterns are carved with lines of varying depths and densities, combining the light and shadow layers and three-dimensionality of traditional Chinese painting.

[0003] Existing electric engraving tools, such as the utility model patent with application number CN201921314246.0, disclose a portable electric engraving pen, which includes an engraving pen body. The engraving pen body includes a shell and a chuck. The tail of the chuck is connected to a drive motor device. The side of the head of the chuck is provided with a threaded hole, and an internal hexagonal locking screw is provided in the threaded hole. The chuck is connected to a grinding head or a cutting head.

[0004] The aforementioned electric engraving pen uses an internal hexagonal locking screw to fix the cutter head. When replacing the cutter head, a special hexagonal wrench is required to remove the internal hexagonal locking screw, making the replacement of the cutter head very inconvenient and requiring improvement. Utility Model Content

[0005] The purpose of this invention is to provide a processing device for gold lacquer openwork engraving, which facilitates the replacement of the cutting head, thereby solving the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A processing device for gold lacquer openwork engraving includes a cylindrical handle. A hollow sleeve is screwed onto the lower outer side of the handle. A drive motor is installed inside the handle. A cylindrical tool holder is coaxially fixed to the rotating shaft of the drive motor. The lower end of the tool holder extends beyond the outer side of the sleeve, and the lower end of the tool holder has a mounting hole for inserting a tool head. The handle, the tool holder, and the mounting hole are coaxially arranged. The opposite sides of the tool holder are respectively provided with slots that radially communicate with the mounting hole. A clamping block for clamping the tool head is movably installed in the slot. The clamping block has a protrusion on the side opposite to the tool head. A sliding sleeve is slidably installed on the outer side of the tool holder along the axial direction. The inner wall of the sliding sleeve has a conical surface that matches the protrusion. The inner diameter of the conical surface gradually decreases from top to bottom. A support component for abutting the lower end of the sliding sleeve is provided inside the sleeve.

[0008] As a further improvement, when the sliding sleeve moves upward, the conical surface abuts against the protrusion and pushes the clamping block to move closer to the cutting head.

[0009] As a further improvement, the protrusion is hemispherical on the side opposite to the clamping block.

[0010] As a further improvement, a limiting pin extending radially is fixedly installed on the outer wall of the tool holder, and a strip hole matching the limiting pin is provided on the sliding sleeve, the length direction of the strip hole extending vertically.

[0011] As a further improvement, the support component is an annular seat rotatably mounted inside the sleeve, the annular seat being coaxially arranged with the tool holder, and the tool holder passing through the annular seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This application allows the sleeve to be loosened clockwise and moved downward relative to the handle, causing the sliding sleeve to follow the sleeve downward and separate the tapered surface from the protrusion, thus releasing the cutter head from the two clamps; or the sleeve can be tightened counterclockwise and moved upward relative to the handle, causing the sleeve to move upward synchronously with the sliding sleeve through the support component. During the upward movement of the sliding sleeve, the tapered surface contacts the protrusion and pushes the clamps towards the cutter head, thereby clamping the cutter head with the two clamps. When replacing the cutter head, no wrench or other tools are needed, making the disassembly and assembly of the cutter head more convenient. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] like Figures 1 to 4 As shown, the processing device for gold lacquer openwork carving includes a cylindrical handle 1, a hollow sleeve 2 screwed onto the lower outer side of the handle 1, an external thread on the lower outer side of the handle 1, and an internal thread on the upper inner side of the sleeve 2 that matches the external thread of the handle 1. Rotating the sleeve 2 allows the sleeve 2 to move up and down relative to the handle 1.

[0022] like Figure 2 As shown, the handle 1 has a motor cavity, in which a drive motor 3 is snapped or fixed by screws. Below the drive motor 3, the handle 1 has a downward-through mounting cavity containing a cylindrical tool holder 4. The upper end of the tool holder 4 has a mounting groove for inserting the rotating shaft of the drive motor 3. The rotating shaft of the drive motor 3 is interference-fitted with the mounting groove to achieve power transmission between the drive motor 3 and the tool holder 4. A first bearing 5 is located between the lower inner wall of the mounting cavity and the tool holder 4, providing support for the tool holder 4 and improving its rotational stability. The drive motor 3 is connected to a control host 19 via wires. The control host 19 has a power cord, a switch, and a knob for adjusting the speed of the drive motor 3.

[0023] The lower end of the tool holder 4 extends beyond the outer side of the sleeve 2, and the lower end of the tool holder 4 is provided with a mounting hole 7 for inserting the tool head 6. The lower end of the sleeve 2 is provided with a positioning hole 8 for the tool holder 4 to pass through. A wear-resistant sleeve that contacts the outer wall of the tool holder 4 is embedded in the inner wall of the positioning hole 8. The handle 1, the tool holder 4, and the mounting hole 7 are coaxially arranged.

[0024] like Figure 3 and Figure 4As shown, in order to fix the cutter head 6, slots 9 with radially connected mounting holes 7 are provided on opposite sides of the cutter holder 4 located inside the sleeve 2. Clamping blocks 10 for clamping the cutter head 6 are movably installed in the slots 9. The inner sides of the two clamping blocks 10 are arc-shaped to match the outer wall of the cutter head 6. In order to improve the clamping effect of the cutter head 6, anti-slip textures or other structures can also be provided on the inner sides of the two clamping blocks 10. A protrusion 11 is integrally formed on the side of the clamping block 10 away from the cutter head 6, and the protrusion 11 extends out of the outer wall of the cutter holder 4.

[0025] A sliding sleeve 12 is slidably installed on the outer side of the tool holder 4 located inside the sleeve 2 along the axial direction. The inner cavities of the upper and lower ends of the sliding sleeve 12 are coaxially arranged straight cylinders. The inner diameter of the upper end of the sliding sleeve 12 is larger and the inner diameter of the lower end is smaller. The inner diameter of the lower end of the sliding sleeve 12 is consistent with the outer diameter of the tool holder 4, which improves the stability of the sliding sleeve 12 sliding along the tool holder 4. A tapered surface 13 matching the protrusion 11 is provided on the inner wall between the upper and lower ends of the sliding sleeve 12. The inner diameter of the tapered surface 13 gradually decreases from top to bottom. A support component for abutting the lower end of the sliding sleeve 12 is provided inside the sleeve 2.

[0026] When the sliding sleeve 12 moves upward, the conical surface 13 abuts against the protrusion 11 and pushes the clamping block 10 to move closer to the cutter head 6.

[0027] When installing the cutter head 6, first loosen the sleeve 2 clockwise so that it moves downward relative to the handle 1. Under the action of gravity, the sliding sleeve 12 will move downward with the sleeve 2, causing the conical surface 13 to separate from the protrusion 11. At this time, the conical surface 13 has no force on the protrusion 11 and the clamping block 10, so that the cutter head 6 can be inserted upward into the mounting hole 7 on the cutter holder 4. In this embodiment, a flared opening is provided between the lower ends of the two clamping blocks 10, which makes it easier for the cutter head 6 to pass upward between the two clamping blocks 10. After the cutter head 6 is inserted into place, tighten the sleeve 2 counterclockwise so that it moves upward relative to the handle 1. Then, the sleeve 2 drives the sliding sleeve 12 to move upward synchronously through the support component. During the upward movement of the sliding sleeve 12, the conical surface 13 contacts the protrusion 11 and pushes the clamping block 10 to move closer to the cutter head 6, thereby clamping the cutter head 6 by the two clamping blocks 10.

[0028] Similarly, when the cutter head 6 needs to be replaced, loosen the sleeve 2 clockwise again so that it moves downward relative to the handle 1. Then the sliding sleeve 12 moves downward with the sleeve 2, separating the conical surface 13 from the protrusion 11. The two clamps 10 release the cutter head 6 so that the cutter head 6 can be removed from the cutter holder 4 for replacement.

[0029] In this embodiment, the side of the protrusion 11 facing away from the clamping block 10 is hemispherical, which can reduce the friction between the protrusion 11 and the conical surface 13.

[0030] The outer wall of the tool holder 4 is screwed with or embedded with a limiting pin 15 extending radially therein. The sliding sleeve 12 is provided with a strip hole 16 that matches the limiting pin 15. The length direction of the strip hole 16 extends vertically. The limiting pin 15 is vertically slidably installed in the strip hole 16 to prevent the sliding sleeve 12 from falling off the tool holder 4.

[0031] The supporting component is an annular seat 18 rotatably mounted inside the sleeve 2 via a second bearing 17. The annular seat 18 is located above the positioning hole 8 and is coaxially arranged with the tool holder 4, through which the tool holder 4 passes. When the drive motor 3 drives the tool holder 4 to rotate, the annular seat 18 can rotate synchronously with the sliding sleeve 12 and the tool holder 4, thereby avoiding friction between the sliding sleeve 12 and the sleeve 2.

[0032] 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 preferred examples and are not intended to limit the 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 claimed utility model.
