The movement of the first fixture block and the second fixture block can be easily controlled through the worm, so that the precious metal raw material can be simply disassembled from the fixture.

[0038] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0039] Please refer to Figures 1 - 5, an embodiment of the present application provides a precious metal clamping device 100, including a fixture housing 1, a first fixture block 2, a second fixture block 3, a worm gear set 4, and a worm 5. The fixture housing 1 is provided with a first sliding groove 6 and a second sliding groove 7 disposed opposite to the first sliding groove 6. The included angle a between the length directions of the first sliding groove 6 and the second sliding groove 7 satisfies the relation 50° ≤ a ≤ 60°. The first fixture block 2 is slidably connected to the first sliding groove 6 and slides along the length direction of the first sliding groove 6. The second fixture block 3 is slidably connected to the second sliding groove 7 and slides along the length direction of the second sliding groove 7. The worm gear set 4 is respectively in transmission connection with the first fixture block 2 and the second fixture block 3. The worm 5 is in transmission connection with the worm gear set 4.

[0040] Specifically, the fixture housing 1 is the outer housing of the entire device. It is provided with a first sliding groove 6 and a second sliding groove 7 opposite thereto. The arrangement of these grooves enables the fixture blocks to slide in a specific direction. The angular design of the fixture housing 1 is between 50° and 60°. This angle selection is to optimize the mechanical structure of the fixture to provide the best stability and operating performance. The first fixture block 2 and the second fixture block 3 are the components used to actually clamp the precious metal. They are respectively connected to the first sliding groove 6 and the second sliding groove 7 and move in a specific direction along their respective grooves. This design allows the fixture blocks to move freely inside the device to flexibly adjust the clamping position. The worm gear set 4 includes a first worm gear 41 and a second worm gear 42, which are respectively in transmission connection with the first fixture block 2 and the second fixture block 3. The worm 5 is in transmission connection with the worm gear set 4, and drives the movement of the fixture blocks through the rotation of the worm gears.

[0041] Further, when the operator rotates the worm 5, the worm gear set 4 will be driven to rotate, so that the first worm gear 41 and the second worm gear 42 rotate. These worm gears are connected to the fixture blocks, so their rotation will cause the fixture blocks to move along the corresponding sliding grooves. By reasonably controlling the rotation direction and speed of the worm 5, the operator can precisely adjust the position of the fixture blocks to achieve the clamping and release of the precious metal.

[0042] In a specific example, the worm gear set 4 includes a first worm gear 41 in transmission connection with the first fixture block 2 and a second worm gear 42 in transmission connection with the second fixture block 3. The worm gear set 4 is located between the first fixture block 2 and the second fixture block 3, and the worm 5 is located between the first worm gear 41 and the second worm gear 42.

[0043] Specifically, the worm gear set 4 is a key component in the clamping device and consists of two worm gear sets 4. The first worm gear 41 is in driving connection with the first fixture block 2, and the second worm gear 42 is in driving connection with the second fixture block 3. This design enables the movement of the fixture blocks to be driven by the worm gears, thereby achieving the clamping and releasing of precious metals. The worm gear set 4 is located between the first fixture block 2 and the second fixture block 3. This position arrangement may be to enable the fixture blocks to be evenly stressed during movement, improving the stability and accuracy of the clamping device. The worm 5 is a key component connecting the worm gear set 4 and is located between the first worm gear 41 and the second worm gear 42. The worm 5 transmits the externally input rotational force to the worm gear set 4 through its driving connection with the worm gears, thereby driving the movement of the fixture blocks. The setting of its position may be to ensure that the worm 5 can effectively transmit force to the worm gear set 4 and make the operation more stable and controllable.

[0044] Furthermore, the setting of the worm gear set 4 enables the fixture blocks to move independently in two directions, achieving precise clamping and releasing of precious metals. The position and driving connection of the worm 5 ensure that the operator can control the movement of the fixture blocks through a simple rotational action, improving the convenience and accuracy of the operation.

[0045] In a specific example, the first fixture block 2 has a first rack 221 that is in driving connection with the first worm gear 41, and the second fixture block 3 has a second rack 321 that is in driving connection with the second worm gear 42.

[0046] Specifically, a special rack is provided on the first fixture block 2, which is designed to be in driving connection with the first worm gear 41. This rack may be a series of protrusions or grooves that cooperate with the corresponding gear racks on the first worm gear 41. This design enables the first fixture block 2 to achieve precise movement through the rotation of the worm gear, thereby clamping or releasing precious metals. Similar to the first fixture block 2, the second fixture block 3 is also equipped with a rack, but it is in driving connection with the second worm gear 42. The function of the second rack 321 is similar to that of the first rack 221. It allows the second fixture block 3 to achieve precise movement relative to the fixture housing 1 through the movement of the second worm gear 42.

[0047] In a specific example, the first fixture block 2 includes a first sliding portion 22 that is slidably connected to the first worm gear 41 and a first clamping portion 21 provided on the first sliding portion 22, and the second fixture block 3 includes a second sliding portion 32 that is slidably connected to the second worm gear 42 and a second clamping portion 31 provided on the second sliding portion 32.

[0048] Specifically, the first sliding portion 22 on the first fixture block 2 is a component that slidably connects with the first worm gear 41. This sliding portion may adopt structures such as sliding bearings or sliders, enabling the first fixture block 2 to smoothly slide along the length direction of the first sliding groove 6 within the fixture housing 1. The first clamping portion 21 provided on the first fixture block 2 is a component for actually clamping the precious metal. It may be a clamping fixture, clamping jaw, or other suitable structure that can clamp or release the precious metal. This clamping portion is located on the first sliding portion 22, ensuring the close combination of the movement and clamping functions of the fixture, so that the fixture can maintain the clamping of the precious metal during sliding. The second sliding portion 32 on the second fixture block 3 is a component that slidably connects with the second worm gear 42. Its structure and function are similar to those of the first sliding portion 22, enabling the second fixture block 3 to smoothly slide along the length direction of the second sliding groove 7 within the fixture housing 1. The second clamping portion 31 provided on the second fixture block 3 is also a component for clamping the precious metal and is located on the second sliding portion 32. This clamping portion corresponds to the first clamping portion 21 and is used to adjust and balance the clamping force and position of the fixture, ensuring the stable clamping of the precious metal.

[0049] In a specific example, the side of the first clamping portion 21 facing the second clamping portion 31 is provided with first anti-slip lines 211, and the side of the second clamping portion 31 facing the first clamping portion 21 is provided with second anti-slip lines 311.

[0050] Specifically, the side of the first clamping portion 21 facing the second clamping portion 31 is provided with first anti-slip lines 211. These anti-slip lines may be an uneven or rough surface texture, aiming to increase the friction between the clamping portion and the surface of the precious metal, preventing the precious metal from sliding or shifting during clamping. Correspondingly, the side of the second clamping portion 31 facing the first clamping portion 21 is provided with second anti-slip lines 311. The function of this anti-slip line is similar to that of the first anti-slip lines 211, also to increase the friction between the clamping portion and the surface of the precious metal, improving the stability and safety of clamping.

[0051] In a specific example, a gripping portion 51 is provided at one end of the worm 5 away from the worm gear set 4.

[0052] Specifically, the worm 5 is a key component in the precious metal clamping device 100. It is usually a spiral-shaped shaft used to transmit rotational force to drive the movement of the worm gear set 4. The gripping portion 51 is a special design on the worm 5 and is located at one end of the worm 5 away from the worm gear set 4. This gripping portion 51 may be a protruding handle, groove, or other structure convenient for the operator to grip.

[0053] Furthermore, the presence of the grasping portion 51 enables the operator to easily hold the worm 5 and conveniently perform the rotation operation. By operating the grasping portion 51, the operator can control the rotation direction and speed of the worm 5, thereby controlling the movement of the worm gear set 4, and further realizing the movement of the fixture block and the clamping of the precious metal. The design of the grasping portion 51 conforms to the ergonomic principle, enabling the operator to easily and comfortably hold the worm 5, reducing the operation fatigue of the user, and improving the operation efficiency and comfort. The setting of the grasping portion 51 makes the precious metal clamping device 100 easier to operate, suitable for various working environments and operation scenarios. Whether it is precision machining in the laboratory or mass production in industrial production, it can be conveniently operated and controlled.

[0054] In a specific example, the fixture housing 1 has a rotation hole 8, and one end of the worm 5 is rotatably connected to the rotation hole 8.

[0055] Specifically, the fixture housing 1 is the outer housing of the entire device. It bears the various components of the device and provides structural support and protection. The rotation hole 8 is provided on the fixture housing 1 to enable the worm 5 to be connected to the fixture housing 1 and control the fixture through rotation. The rotation hole 8 is a hole on the fixture housing 1, usually having a circular or cylindrical structure, and its function is to provide a rotation fulcrum for the worm 5. Through the rotation hole 8, the worm 5 can freely rotate within the fixture housing 1, thereby controlling the movement of the worm gear set 4 and realizing the movement of the fixture block and the clamping of the precious metal. One end of the worm 5 in the precious metal clamping device 100 is rotatably connected within the rotation hole 8 on the fixture housing 1. This design enables the worm 5 to be firmly fixed on the fixture housing 1 and freely rotate within the rotation hole 8, facilitating the operation of the operator.

[0056] In a specific example, the fixture housing 1 includes a first housing 11 and a second housing 12 detachably connected to the first housing 11, and the worm gear set 4 is located between the first housing 11 and the second housing 12.

[0057] Specifically, the first housing 11 is the main part of the fixture housing 1 and is usually the basic structure of the entire fixture housing 1. It fixes various components of the fixture device, such as the worm gear set 4, fixture blocks, etc. The first housing 11 generally bears the main forces and pressures of the device and provides stability and structural support for the device. The second housing 12 is another housing detachably connected to the first housing 11. This design allows the second housing 12 to be easily separated from the first housing 11, facilitating the maintenance, repair, or cleaning of the device. The second housing 12 may be connected to the first housing 11 by threaded connection, snap connection, or other means to ensure the stability and safety of the device during use. The worm gear set 4 is located between the first housing 11 and the second housing 12. This layout may be to place key components such as the worm gear set 4 and transmission components inside the fixture housing 1 to protect them from interference and damage from the external environment. At the same time, this can also make the fixture housing 1 more compact, reduce space occupancy, and improve the overall efficiency and usability of the device.

[0058] In a specific example, the first housing 11 and the second housing 12 are bolted together.

[0059] Specifically, the first housing 11 and the second housing 12 are two parts that make up the outer shell of the precious metal clamping device 100. The first housing 11 is the main structure of the device, carrying various components of the fixture device, while the second housing 12 is another housing detachably connected to the first housing 11. A bolt is a common connecting piece, usually consisting of a screw rod and a nut, and two or more components are fixed together by rotating the bolt. In this case, when using a bolt connection between the first housing 11 and the second housing 12, holes may need to be drilled in the first housing 11 and the second housing 12 respectively, and then they are tightly fixed together by bolts. The bolt connection provides a firm and reliable connection method, which can ensure the stable connection between the first housing 11 and the second housing 12, so that the device will not loosen or fall off due to external forces during use. The design of the bolt connection makes the disassembly and assembly between the first housing 11 and the second housing 12 more convenient. The operator can easily complete the disassembly and assembly operations of the fixture housing 1 by tightening or loosening the bolts. This connection method also makes the fixture device easier to maintain and repair. If maintenance or component replacement is required for the device, the operator only needs to remove the bolts to quickly access the inside of the fixture housing 1.

[0060] In a specific example, a first bearing 411 is provided between the first worm gear 41 and the fixture housing 1, and the first worm gear 41 is rotatably connected to the fixture housing 1 through the first bearing 411. A second bearing 421 is provided between the second worm gear 42 and the fixture housing 1, and the second worm gear 42 is rotatably connected to the fixture housing 1 through the second bearing 421.

[0061] Specifically, the first worm gear 41 and the second worm gear 42 are key components in the precious metal clamping device 100, usually cylindrical or disc-shaped, for transmitting force and driving the movement of the fixture block. There are bearing connections between them and the fixture housing 1 respectively. The first bearing 411 and the second bearing 421 are circular bearing components for supporting and fixing the worm gears. The first bearing 411 is located between the first worm gear 41 and the fixture housing 1, and the second bearing 421 is located between the second worm gear 42 and the fixture housing 1. These bearings can reduce the friction and wear of the worm gears during rotation, ensuring the smooth operation of the worm gears. The first worm gear 41 is rotatably connected to the fixture housing 1 through the first bearing 411, and the second worm gear 42 is rotatably connected to the fixture housing 1 through the second bearing 421. This connection method enables the worm gears to rotate smoothly inside the fixture housing 1, while ensuring the structural stability between the worm gears and the fixture housing 1, improving the operation accuracy and reliability of the clamping device.

[0062] The above are only the embodiments of the present application. It should be noted here that for those of ordinary skill in the art, without departing from the inventive concept of the present application, improvements can still be made, but these all fall within the protection scope of the present application.
