Description

Technical Field

[0001] This utility model relates to the field of diamond cutting technology, and in particular to a positioning device for diamond cutting. Background Technology

[0002] Diamonds, as a precious gemstone, require extremely high precision in cutting during processing. The quality of the cut directly affects the diamond's appearance and value. Before cutting a diamond, it needs to be precisely positioned to ensure the accuracy and consistency of the cut. Most existing positioning devices can only position and cut one diamond at a time, which wastes a lot of time and reduces the efficiency of diamond cutting.

[0003] A search revealed a diamond-cutting positioning device in patent application number 202321575070.0. This device utilizes multiple placement slots on the top of a turntable, rotating the turntable to continuously cut multiple diamonds, thus improving cutting efficiency. However, in practical use, after cutting, the diamonds positioned in the placement slots with sealing wax need to be completely removed, and residual sealing wax residue needs to be cleaned. Since the sealing wax adheres to the inner wall of the placement slots after curing, conventional cleaning methods require using sharp tools such as tweezers and scrapers to peel it off from the inside of the slots. This is not only time-consuming and laborious but also easily leaves scratches on the surface of the placement slots, affecting subsequent accuracy. While disassembling the placement slots for emptying and cleaning avoids direct damage to the slots, it requires repeated disassembly and reassembly of the fixing device, increasing the operational steps and making it cumbersome. Therefore, this paper proposes a diamond-cutting positioning device. Utility Model Content

[0004] This invention proposes a positioning device for diamond cutting to solve the problem of time-consuming, labor-intensive, and cumbersome operation when cleaning the sealing wax in the placement groove.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for diamond cutting, comprising a base plate and a rotating plate disposed above the base plate. The upper end face of the rotating plate is provided with a plurality of diamond placement components arranged in a circular array. Each diamond placement component includes a detachably connected support column and a placement cylinder. The support column is fixed to the upper end face of the rotating plate. A piston is disposed inside the placement cylinder. A placement groove is located inside the placement cylinder and above the piston. The device also includes a lifting assembly, which is used to synchronously lift and lower the plurality of pistons.

[0006] Preferably, the lifting assembly includes a piston rod connected to the lower end face of the piston, the piston rod passing through the support column and the rotating plate, and the bottom ends of all the piston rods are connected to an annular support bar, and a telescopic rod is installed between the lower end face of the annular support bar and the base plate.

[0007] Preferably, the lower end of the outer wall of the piston rod is provided with an external thread, and the upper end face of the annular support bar is provided with a corresponding threaded connection groove.

[0008] Preferably, the support column and the placement cylinder are threaded together.

[0009] Preferably, all the telescopic rods have a common annular movable strip at their bottom ends, and the annular movable strip is rotatably connected to the upper end face of the base plate.

[0010] Preferably, it also includes a rotating assembly for rotating the rotating plate.

[0011] Preferably, the rotating assembly includes a motor mounted on a base plate, a drive gear mounted on the output end of the motor, a support shaft fixedly connected to the middle of the bottom end of the rotating plate, a driven gear mounted on the outside of the support shaft, and the driven gear meshing with the drive gear.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] (1) The lifting assembly can synchronously control the lifting of all pistons. When the piston rod pushes the piston up, the depth of the placement groove can be reduced. When the piston rod pulls the piston up and down, the depth of the placement groove can be increased, which is more flexible. When cleaning the cured sealing wax, the piston can push the sealing wax directly out from the top of the placement groove without manually disassembling the placement cylinder piece by piece or using tools to clean it, which greatly reduces the operation steps. In addition, the telescopic rod can realize the piston to lift up and down repeatedly in a periodic manner, which further improves the thoroughness of sealing wax cleaning.

[0014] (2) The diamond placement component adopts a detachable connection design between the support column and the placement tube. By replacing the placement tube with a different inner diameter, it can be adapted to diamonds of different sizes. At the same time, the piston and piston rod assembly can be replaced synchronously with the placement tube, which significantly improves the adaptability to diamond specifications.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] This utility model provides, for example Figures 1-6 The diamond cutting positioning device shown includes a base plate 1 and a rotating plate 3 disposed above the base plate 1. A frame 2 is fixed above the base plate 1 by a support rod. The frame 2 is located around the rotating plate 3, and a waste discharge port 21 is provided on the side wall of the frame 2. A plurality of diamond placement components 4 are arranged in a circular array on the upper end face of the rotating plate 3. Each diamond placement component 4 includes a detachably connected support post 41 and a placement cylinder 42. The upper and lower ends of the placement cylinder 42 are open, and the inner wall of the placement cylinder 42 is smooth. Preferably, the support post 41 and the placement cylinder 42 are threadedly connected. Specifically, an external thread groove can be provided on the upper end of the outer wall of the support post 41. The lower end of the inner wall of the placement cylinder 42 is provided with an internal thread groove to achieve threaded connection and detachable connection, which facilitates the replacement of the placement cylinder 42 to accommodate diamonds of different sizes. The support column 41 is fixed to the upper end face of the rotating plate 3. The placement cylinder 42 is provided with a piston 44. The upper end face of the piston 44 is hard and heat resistant. The inner wall of the placement cylinder 42 and the upper end face of the piston 44 are provided with a heat resistant anti-stick layer to facilitate the removal of the sealing wax. Inside the placement cylinder 42 and above the piston 44 is a resting groove 45. The diamond is positioned in the resting groove 45 by the sealing wax. It also includes a lifting assembly, which is used to make multiple pistons 44 rise and fall synchronously.

[0025] Among them, see Figure 2 and Figure 3 As shown, the lifting assembly includes a piston rod 43 connected to the lower end face of the piston 44. The piston rod 43 passes through the support column 41 and the rotating plate 3. The rotating plate 3 has multiple through holes 31 arranged in a ring array. The piston rod 43 passes through the corresponding through holes 31. The bottom ends of all piston rods 43 are connected to an annular support bar 7. A telescopic rod 6 is installed between the lower end face of the annular support bar 7 and the base plate 1. The telescopic rod 6 can be an electric or pneumatic telescopic rod. When the telescopic rod 6 is activated, the annular support bar 7 can be raised or lowered by the telescopic rod 6, thereby using the piston rod 43 to push the piston 44 up or pull the piston 44 down.

[0026] When the piston rod 43 pushes the piston 44, the depth of the shelf 45 can be reduced. Secondly, when cleaning the cured sealing wax, the piston 44 can be used to push the cured sealing wax upward, so that the cured sealing wax is pushed out from the top of the shelf 45. There is no need for staff to use tools to clean it, nor is it necessary to disassemble the placement cylinder 42 one by one. It is more convenient and time-saving. The sealing wax pushed out from the shelf 45 can fall on the rotating plate 3. After a certain amount, it can be discharged and collected from the waste discharge port 21 on the frame 2 by sweeping.

[0027] When the piston rod 43 pulls down the piston 44, the depth of the support groove 45 can be increased to accommodate different cutting requirements.

[0028] In addition, by using the telescopic rod 6 to periodically raise and lower the piston 44 multiple times when cleaning the sealing wax in the shelf 45, the thoroughness of the cleaning can be improved.

[0029] See Figure 3 as well as Figures 5-6 As shown, the lower end of the outer wall of the piston rod 43 is provided with an external thread 431, and the upper end face of the annular support 7 is provided with a corresponding threaded connection groove. The piston rod 43 is threadedly connected to the annular support 7, which realizes the detachable installation of the piston rod 43. When replacing the placement cylinder 42 of the larger or smaller inner diameter support groove 45, the piston 44 of different diameters can be replaced at the same time (the piston rod 43 is fixed on the lower end face of the piston 44).

[0030] It should be noted that pistons 44 of different diameters are equipped with piston rods 43 of the same diameter so that they can all be screwed onto the annular support bar 7.

[0031] Additionally, it should be noted that the bottom ends of the placement cylinders 42 with larger or smaller inner diameter placement grooves 45 are all adapted to the screw-on support column 41, resulting in some placement cylinders 42 being larger at the top and smaller at the bottom (placement cylinders 42 with larger inner diameter placement grooves 45), while others are smaller at the top and larger at the bottom (placement cylinders 42 with smaller inner diameter placement grooves 45).

[0032] See Figures 1-2As shown, all telescopic rods 6 have a common annular movable bar 8 at their bottom ends. The annular movable bar 8 is rotatably connected to the upper end face of the base plate 1. Specifically, the annular movable bar 8 can be rotatably connected to the upper end face of the base plate 1 through an embedded bearing, and can achieve smooth and jam-free rotation within a 360-degree range.

[0033] See Figures 2-3 As shown, it also includes a rotating assembly 5, which is used to realize the rotation of the rotating plate 3;

[0034] The rotating assembly 5 includes a motor 51 mounted on the base plate 1. A drive gear 52 is mounted on the output end of the motor 51. A support shaft 53 is fixedly connected to the middle of the bottom end of the rotating plate 3. The bottom end of the support shaft 53 is connected to the base plate 1 through a bearing seat. A driven gear 54 is mounted on the outside of the support shaft 53. The driven gear 54 meshes with the drive gear 52.

[0035] By starting the motor 51, the output of the motor 51 can drive the drive gear 52 to rotate, and the drive gear 52 drives the meshing passive gear 54 to rotate, thereby realizing the rotation of the support shaft 53, so as to realize the rotation of the rotating plate 3. This allows the diamond to be quickly switched during cutting, and multiple diamonds can be cut continuously, improving the diamond cutting efficiency.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
