Description

Technical Field

[0001] The invention relates to the technical field of diamond processing, and in particular to a cutting device for diamond processing. Background Art

[0002] Diamond is a natural element mineral composed of carbon. It is the hardest substance naturally existing in nature. After being obtained from nature, diamond needs to be processed again. Cutting is an important step in diamond processing. Due to the hard texture of diamond, it takes a long time to cut and the cutting blade needs to be cooled in time.

[0003] However, the existing cutting device for diamond processing still has the following defects during use:

[0004] 1. Since diamond cutting takes a long time, in order to save effort, the existing cutting device will use a counterweight to achieve long-term stable extrusion contact between the diamond and the cutting blade. However, the position of the counterweight block of the existing cutting device remains unchanged during the cutting process, so the downward pressure on the diamond is also unchanged. However, as the cutting proceeds, the cutting blade will penetrate deeper into the diamond, and at the same time, the friction will increase, and the hardness of the cutting blade will decrease due to heat. Therefore, the efficiency of the later cutting will decrease, reducing the cutting effect.

[0005] 2. When cooling the cutting blade, the existing cutting device achieves this by immersing the bottom of the cutting blade in cooling water. However, the depth of the bottom of the cutting blade immersed in the cooling water is the same. As the cutting progresses, the cutting blade will penetrate deeper into the diamond, so a larger area of the cutting blade will generate friction and heat, which is prone to poor cooling effect in the later stage of cutting. If the cutting blade is immersed in a greater depth at the beginning, when cutting begins, a large amount of cooling water will be raised as the cutting blade rotates, which is not conducive to normal cutting. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the downward pressure of the diamond on the above-mentioned existing cutting device remains unchanged, but as the cutting blade goes deeper, the efficiency of subsequent cutting will decrease, thereby reducing the cutting effect, and the depth of the bottom of the cutting blade immersed in cooling water is the same, and it is impossible to avoid raising a large amount of cooling water while also being able to fully cool the cutting blade in the later stage. The present invention provides a cutting device for diamond processing.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] A cutting device for diamond processing, comprising a machine body. A rotating shaft is drivingly connected to the right side of the top of the machine body. A cutting blade is fixedly installed around the middle of the rotating shaft. A cutting assembly is arranged at the top of the right side of the machine body. The cutting assembly is used for the installation and moving cutting of diamonds. A cooling assembly is arranged inside the front of the right side of the machine body. The cooling assembly is used for cooling the cutting blade during the cutting process. An automatic adjustment assembly is arranged between the cutting assembly and the cooling assembly.

[0009] Furthermore, the cutting assembly includes a sliding seat. The sliding seat is limited and slidably connected inside the rear of the right side of the machine body. A swing arm is limited and hinged to the top of the sliding seat. A two-dimensional rotating head is fixedly installed on the front side of the swing arm. The two-dimensional rotating head can be rotated and tilted to adjust, so as to realize the cutting of diamonds at multiple angles and positions. A clamp is fixedly installed at the bottom end of the two-dimensional rotating head. The clamp is used for the installation of diamonds. A rear counterweight is fixedly installed at the top end of the rear side of the swing arm. An installation seat is limited and slidably connected inside the front side of the swing arm. A front counterweight is fixedly installed at the top end of the installation seat. A threaded rod is limited and rotatably connected inside the rear of the right side of the machine body. The threaded rod penetrates through the sliding seat and is threadedly connected to the sliding seat. Therefore, when the threaded rod rotates, it can drive the sliding seat to move left and right.

[0010] Furthermore, the rear counterweight is used to make the swing arm stably tilt backward for parking when the cutting stops, and the counterweight block of the rear counterweight can be adjusted in position to ensure that the swing arm can tilt backward.

[0011] Furthermore, the front counterweight is used to apply a downward pressure on the swing arm, so that the diamond installed on the clamp is in extrusion contact with the cutting blade downward.

[0012] Furthermore, a differential head is inserted into the rear side of the right end of the machine body, and the differential head is drivingly connected to the threaded rod. The differential head is used to drive the threaded rod to rotate and more precisely control the movement of the sliding seat driven by the rotation of the threaded rod.

[0013] Further, the cooling component includes a drawer slot. An internal drawer slot is provided in the front of the right side of the body. A square hole is provided above the drawer slot on the right side of the body. The square hole penetrates through the top of the body and is connected to the drawer slot. Partition slots are symmetrically provided on the left and right sides of the internal drawer slot of the body. Slide grooves I are provided on the front and rear sides between the partition slots on the left and right sides and the drawer slot. Slide grooves II are provided between the partition slots on the left and right sides and the drawer slot, and the slide groove II is located between the front and rear slide grooves I. A placement frame is connected to the inside of the drawer slot in a vertically limited sliding manner. A water storage box is limited and clamped inside the placement frame. Cutting piece cooling water is placed inside the water storage box. The front and rear sides of the left and right ends of the placement frame are symmetrically and rotationally connected with pulleys in a limited manner, and the pulleys are in limited rolling connection with the slide groove I, so as to realize the vertically limited sliding of the placement frame with low friction by the cooperation of the pulley and the slide groove I.

[0014] Further, openings are provided on the top and front side of the placement frame, and elastic cards are fixedly installed at the left and right side walls inside the placement frame. The design of the elastic cards facilitates the limited clamping of the water storage box from the front side of the placement frame.

[0015] Further, the self-adjusting component includes inclined rods. Inclined rods are symmetrically and rotationally connected to the left and right sides of the swing arm at the top of the right side of the body in a limited manner. A horizontal shaft is fixedly installed between the sides of the left and right inclined rods away from the body. Transmission rods are rotationally connected to the middle parts of the left and right inclined rods in a limited manner. The side of the transmission rod away from the inclined rod extends downward into the inside of the partition slot. Slide rods are fixedly installed between the adjacent ends of the sides of the left and right transmission rods away from the inclined rod. Inclined slots are symmetrically provided on the left and right sides of the placement frame.

[0016] Further, the horizontal shaft penetrates through the mounting seat, so that the mounting seat can perform limited left and right sliding on the outside of the horizontal shaft. While the swing arm can be adjusted left and right, the movement of the horizontal shaft can also drive the mounting seat to move.

[0017] Further, the slide rod is located inside the slide groove II. The slide rod can perform limited front and rear sliding through the limitation of the slide groove II. And the slide rod extends to the inside of the inclined slot toward the adjacent side. Through the cooperation of the slide rod and the inclined slot, when the slide rod performs limited sliding from the rear to the front, the placement frame can be pushed upward, thereby driving the water storage box to move upward, so that the cutting piece can be immersed deeper into the cooling water downward.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, through the cooperative design of the cutting component and the self-adjusting component, during the cutting process, the front-end counterweight can be pushed to move towards the side away from the hinge point of the swing arm, so as to increase the downward pressure on the diamond. Therefore, during the cutting process, the downward pressure on the diamond is gradually increased, avoiding the situation that the cutting efficiency decreases due to the gradual deepening of the cutting blade and the gradual increase of the friction force in the later stage, and enabling more uniform and stable cutting, thus improving the cutting effect.

[0020] 2. In the present invention, through the cooperative design of the cooling component and the self-adjusting component, during the cutting process, the water storage box filled with cooling water can be gradually moved upward. Thus, in the initial stage of cutting, the cutting blade is not deeply immersed in the cooling water, avoiding a large amount of splashing of the cooling water. As the cutting progresses and the cutting blade gradually penetrates into the diamond, when a larger area of the cutting blade is subjected to frictional heat, the cutting blade can be immersed deeper in the cooling water, thereby achieving a better cooling effect and ensuring the normal progress of cutting.

Detailed implementation

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] A cutting device for diamond processing according to a preferred embodiment of the present invention will be described in detail below, as Figure 1 - Figure 2 shown, a cutting device for diamond processing includes a body 1. A rotating shaft 2 is drivingly connected to the right side of the top of the body 1. A cutting blade 3 is fixedly installed around the middle of the rotating shaft 2. A cutting assembly 4 is provided on the top right side of the body 1. The cutting assembly 4 is used for the installation and moving cutting of diamonds. A cooling assembly 5 is provided inside the front right side of the body 1. The cooling assembly 5 is used for cooling the cutting blade 3 during the cutting process. A self-adjusting assembly 6 is provided between the cutting assembly 4 and the cooling assembly 5.

[0033] Further, as Figure 5 - Figure 8 shown, the cutting assembly 4 includes a sliding seat 41. The sliding seat 41 is slidably connected in a limited manner inside the rear right side of the body 1. The top of the sliding seat 41 is hinged in a limited manner to a swing arm 42. A two-dimensional rotating head 43 is fixedly installed on the front side of the swing arm 42. The two-dimensional rotating head 43 can be rotated and tilted to adjust, so as to realize the cutting of diamonds at multiple angles and positions. A fixture 44 is fixedly installed at the bottom end of the two-dimensional rotating head 43. The fixture 44 is used for the installation of diamonds.

[0034] A rear counterweight 45 is fixedly installed at the top end of the rear side of the swing arm 42. The rear counterweight 45 is used to make the swing arm 42 stably tilt backward and park when the cutting stops, and the counterweight block of the rear counterweight 45 can be adjusted in position to ensure that the swing arm 42 can tilt backward.

[0035] An installation seat 46 is slidably connected in a limited manner inside the front side of the swing arm 42. A front counterweight 47 is fixedly installed at the top end of the installation seat 46. The front counterweight 47 is used to apply a downward pressure to the swing arm 42, so that the diamond installed on the fixture 44 is in downward extrusion contact with the cutting blade 3.

[0036] A threaded rod 48 is internally and rotationally connected in a limited manner at the rear right side of the machine body 1. The threaded rod 48 penetrates through the sliding seat 41 and is in threaded connection with the sliding seat 41. Therefore, when the threaded rod 48 rotates, it can drive the sliding seat 41 to move left and right.

[0037] A differential head 7 is inserted at the rear side of the right end of the machine body 1, and the differential head 7 is in transmission connection with the threaded rod 48. The differential head 7 is used to drive the threaded rod 48 to rotate and more precisely control the movement of driving the sliding seat 41 by the rotation of the threaded rod 48.

[0038] Furthermore, as Figure 1 - Figure 6 , Figure 9 shown, the cooling component 5 includes a drawer slot 51. The drawer slot 51 is internally opened at the front right side of the machine body 1. A square hole 52 is opened above the drawer slot 51 on the right side of the machine body 1. The square hole 52 penetrates through the top of the machine body 1 and is communicated with the drawer slot 51. Partition slots 53 are symmetrically opened on the left and right sides of the drawer slot 51 inside the machine body 1. Slide grooves 54 are opened on the front and rear sides between the partition slots 53 on the left and right sides and the drawer slot 51. Slide grooves 55 are opened between the partition slots 53 on the left and right sides and the drawer slot 51, and the slide grooves 55 are located between the slide grooves 54 on the front and rear sides. A placement frame 56 is connected in a limited and sliding manner up and down inside the drawer slot 51. A water storage box 57 is connected in a limited and clamped manner inside the placement frame 56. Openings are provided at the top and front side of the placement frame 56, and elastic cards 561 are fixedly installed at the left and right side walls inside the placement frame 56. Through the design of the elastic cards 561, it is convenient to achieve the limited clamping of the water storage box 57 from the front side of the placement frame 56.

[0039] Cooling water for the cutting blade 3 is placed inside the water storage box 57. Pulleys 58 are symmetrically and rotationally connected in a limited manner at the front and rear sides of the left and right ends of the placement frame 56, and the pulleys 58 are in limited rolling connection with the slide grooves 54. The cooperation of the pulleys 58 and the slide grooves 54 is used to achieve the up and down limited sliding of the placement frame 56 with low friction.

[0040] Furthermore, as Figure 5 - Figure 7 shown, the self-adjusting component 6 includes an inclined rod 61. The inclined rods 61 are symmetrically and rotationally connected in a limited manner at the left and right sides of the swing arm 42 at the top right side of the machine body 1. A cross shaft 62 is fixedly installed between the sides of the left and right inclined rods 61 away from the machine body 1. Transmission rods 63 are rotationally connected in a limited manner at the middle parts of the left and right inclined rods 61. The transmission rods 63 extend downward to the inside of the partition slot 53 at the side away from the inclined rod 61. Slide rods 64 are fixedly installed between the adjacent ends of the left and right transmission rods 63 at the side away from the inclined rod 61. Inclined slots 65 are symmetrically opened on the left and right sides of the placement frame 56.

[0041] The horizontal axis 62 runs through the mounting base 46, enabling the mounting base 46 to perform left-right limiting sliding on the outer side of the horizontal axis 62. While the swing arm 42 can be adjusted left and right, the movement of the horizontal axis 62 can also drive the mounting base 46 to move.

[0042] The slide bar 64 is located inside the second chute 55. Through the limitation of the second chute 55, the slide bar 64 can perform front-back limiting sliding. And the slide bar 64 extends to the inside of the inclined chute 65 towards the adjacent side. Through the cooperation of the slide bar 64 and the inclined chute 65, when the slide bar 64 performs front-back limiting sliding from the back to the front, it can push the placement frame 56 upward, thereby driving the water storage box 57 upward to make the cutting blade 3 sink deeper into the cooling water.

[0043] The working principle of the present invention is:

[0044] When preparing for cutting, the rear counterweight 45 is fixedly installed at the top of the rear side of the swing arm 42, and the front counterweight 47 is fixedly installed at the top of the mounting base 46 on the front side of the swing arm 42. Then, the water storage box 57 is pushed into the top of the placement frame 56 from the front side, and the elastic card 561 inside the placement frame 56 is used to limit and clamp the water storage box 57. Then, the cutting blade 3 is fixedly installed on the rotating shaft 2. After the installation is completed, the water baffle 59 is clamped at the square hole 52. Finally, cooling water is added to the inside of the water storage box 57.

[0045] When cutting, the diamond is fixedly installed at the fixture 44, and the angle and position of the fixed diamond are adjusted through the two-dimensional rotating head 43. Then, the rotating shaft 2 is driven to rotate, so that the rotating shaft 2 drives the cutting blade 3 to rotate, and the swing arm 42 is turned downward, so that the swing arm 42 drives the fixed diamond to contact the rotating cutting blade 3 downward, thereby realizing the cutting of the cutting blade 3 on the diamond.

[0046] During the cutting process, through the design of the front counterweight 47, a downward pressure can be applied to the diamond. Therefore, continuous cutting of the diamond can be achieved without manually pressing the swing arm 42 downward. At the same time, by using the cooling water added to the inside of the water storage box 57, the outer ring of the cutting blade 3 immersed in the cooling water can be cooled to ensure the normal progress of cutting. After a single cutting is completed, the swing arm 42 is turned upward. With the design of the rear counterweight 45, the swing arm 42 can be stably tilted backward and parked.

[0047] When the cutting position needs to be adjusted, the differential head 7 is rotated to drive the threaded rod 48 to rotate. During the rotation of the threaded rod 48, due to the threaded connection between the threaded rod 48 and the slide seat 41, the slide seat 41 can be driven to move left and right, thereby driving the swing arm 42 and the installed diamond to move left and right, so that the contact position between the diamond and the cutting blade 3 after the diamond moves down following the swing arm 42 is changed, thus realizing the adjustment of the cutting position. At the same time, through the design of the differential head 7, the adjustment of the cutting position can also be controlled more precisely.

[0048] It should be noted that during the process of the swing arm 42 driving the diamond to gradually move down for cutting, through the action of the inclined rod 61, during the inclined rotation of the inclined rod 61, the mounting seat 46 can be pushed to move forward inside the front side of the swing arm 42 through the cross shaft 62, and then the front-end counterweight 47 is pushed to move towards the side away from the hinge point of the swing arm 42, so as to increase the downward pressure on the diamond. Therefore, during the cutting process, the downward pressure on the diamond is gradually increased, avoiding the situation of decreased cutting efficiency due to the gradual deepening of the cutting blade 3 and the gradual increase in friction in the later stage, and enabling more uniform and stable cutting, improving the cutting effect.

[0049] While the inclined rod 61 is inclined and rotating, through the design of the transmission rod 63, the slide rod 64 can be pushed to move forward inside the second chute 55. During the forward movement of the slide rod 64, by utilizing the cooperation between the slide rod 64 and the inclined slots 65 on the left and right sides of the placement frame 56, and the up-and-down limiting sliding connection of the placement frame 56 in the drawer slot 51 through the cooperation of the placement frame 56 with the pulley 58 and the first chute 54, the placement frame 56 can be driven to move upward, thus realizing that during the cutting process, the water storage box 57 filled with cooling water can be gradually moved upward, so that the cutting blade 3 is immersed deeper in the cooling water. Furthermore, at the initial stage of cutting, the cutting blade 3 is not immersed deeply in the cooling water, avoiding a large amount of splashing of the cooling water. As the cutting progresses, when the cutting blade 3 gradually penetrates into the diamond and a larger area of the cutting blade 3 is subjected to frictional heat, the cutting blade 3 can be immersed deeper in the cooling water, thereby achieving a better cooling effect and ensuring the normal progress of cutting.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
