Description

Technical Field

[0001] The utility model relates to the technical field of sapphire ingot processing and manufacturing, and particularly relates to a diamond cylinder cutter handle with quick loading and unloading. Background Art

[0002] The main manufacturing method of sapphire ingots is to drill the ingots. A diamond cylinder cutter is used to extract the sapphire ingot from the sapphire ingot. However, the diamond cylinder cutter belongs to a consumable auxiliary material and needs to be replaced in time during the processing. At present, in the industry, the diamond cylinder cutter handles of various brands of drilling equipment all adopt the method of "fixing between the handle and the equipment spindle by multiple setscrews". During the clamping and disassembling process, a matching wrench is required to rotate each setscrew one by one, resulting in a cumbersome clamping problem. On the other hand, sapphire debris is likely to enter between the handle and the spindle, resulting in problems such as the handle getting stuck and being difficult to disassemble during disassembly.

[0003] Therefore, there is an urgent need for a diamond cylinder cutter handle that can be conveniently and quickly loaded and unloaded. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of cumbersome clamping of the existing diamond cylinder cutter and the handle getting stuck and being difficult to disassemble due to the retention of sapphire debris during the disassembly process, and further provide a diamond cylinder cutter handle with quick loading and unloading.

[0005] The technical solution of the utility model is as follows:

[0006] A diamond cylinder cutter handle with quick loading and unloading includes a handle pin 1 and a handle pin sleeve 2. The handle pin 1 includes a pin body 11, a locking key 12, and a flange 13. The flange 13 is horizontally arranged. Above the flange 13, there is a coaxially arranged pin body 11. The pin body 11 is a cylindrical pin body. The lower end of the cylindrical pin body is fixedly connected to the upper end of the flange 13. On the upper side of the cylindrical pin body, there is a locking key 12. The side of the locking key 12 is processed into a first arc surface 121. The handle pin sleeve 2 is a hollow cylindrical structure with a closed end cover at the upper end. The lower end of the handle pin sleeve 2 is sleeved on the upper part of the handle pin 1. On the handle pin sleeve 2, there is a keyway 21 that matches the shape of the locking key 12. The number of the keyways 21 is equal to that of the locking keys 12 and the positions correspond. At the top of each keyway 21, there is a locking groove 22. The side of the locking groove 22 is processed into a second arc surface 221.

[0007] Furthermore, the radian of the first arc surface 121 gradually decreases counterclockwise with the axis of the cylindrical pin body as the center. The radian of the second arc surface 221 gradually decreases counterclockwise with the axis of the cylindrical pin body as the center. The intersection of the second arc surface 221 and the first arc surface 121 has a smooth transition.

[0008] Furthermore, the number of the locking keys 12 is not less than two, and the locking keys 12 are equidistantly distributed along the circumferential direction on the side of the cylindrical pin body.

[0009] Furthermore, the keyway 21 penetrates through the lower end face of the tool shank pin sleeve.

[0010] Furthermore, a first central through hole 131 penetrating through both end faces of the flange 13 is machined on the flange 13, and a second central through hole 23 penetrating through both end faces of the closing end cover is machined on the closing end cover. The first central through hole 131 and the second central through hole 23 are arranged coaxially opposite to each other, and the first central through hole 131 and the second central through hole 23 are used for communicating with circulating cooling water.

[0011] Furthermore, the tool shank pin sleeve 2 and the tool shank pin 1 are arranged coaxially, and the fitting mode of the tool shank pin sleeve 2 and the tool shank pin 1 is clearance fit.

[0012] Furthermore, the upper end of the tool shank pin sleeve 2 is connected to the drill spindle, and the lower end of the flange 13 is connected to the diamond core drill.

[0013] The utility model has the following effects compared with the prior art:

[0014] 1. For the quick-loading and unloading diamond core drill tool shank of the utility model, the clamping and fixing method using the locking key 12 and the locking groove 22 makes the installation and disassembly of the diamond core drill quicker and more efficient, avoiding the tediousness of the traditional set screw fixing method.

[0015] 2. The tool shank pin 1 and the tool shank pin sleeve 2 of the utility model adopt the clearance fit mode, enabling the smooth discharge of sapphire debris generated during the process of extracting the rod, and solving the problems of tool shank jamming and difficult disassembly caused by the retention of sapphire debris during the disassembly of the diamond core drill.

With such a setting, the size of the second arc surface 221 of the locking groove 22 gradually contracts with the change of the angle. The other compositions and connection relationships are the same as those in detailed implementation manner one.

[0027] Detailed implementation manner three: With reference to Figures 1 to 7Describing this embodiment, the number of locking keys 12 in this embodiment is not less than two, and the locking keys 12 are equidistantly distributed along the circumferential direction on the side surface of the cylindrical pin body. With such a setting, multiple locking keys 12 are equidistantly distributed on the side surface of the pin body 11, making the state of the tool shank pin 1 more stable during rotation. The other components and connection relationships are the same as those in the first or second specific embodiment.

[0028] Specific embodiment four: Combining Figures 1 to 7 Describing this embodiment, the keyway 21 in this embodiment runs through the lower end face of the tool shank pin sleeve.

[0032] Working principle

[0033] Combining Figures 1 to 7Describe the working principle of the quick-installation and removal diamond cylinder cutter handle of the present utility model: The top of the handle pin sleeve 2 is installed on the drill press spindle, and the diamond cylinder cutter is installed on the flange 13 at the lower part of the handle pin 1. When the handle pin 1 is inserted into the handle pin sleeve 2, the locking key 12 moves upward along the keyway 21 to reach the locking groove 22. After the equipment is started, the drill press spindle rotates to drive the handle pin sleeve 2 to rotate, and the locking key 12 of the handle pin 1 undergoes a lateral displacement in the locking groove 22. As the locking groove 22 gradually converges inward, the pressure on the locking key 12 continuously increases, fixing the handle pin 1 in the handle pin sleeve 2. After the use of the diamond cylinder cutter is completed, reverse the rotation of the equipment spindle. The locking key 12 of the handle pin 1 undergoes a reverse displacement in the locking groove 22. As the locking groove 22 gradually expands outward, the pressure on the locking key 12 decreases until the locking key 12 reaches the top of the keyway 21, and the locking key 12 moves downward along the keyway 21 until the handle pin 1 is separated from the handle pin sleeve 2, completing the removal of the handle pin 1. Repeat the above steps to insert another handle pin 1 with a diamond cylinder cutter into the handle pin sleeve 2 to complete the replacement of the diamond cylinder cutter.

[0034] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
