[0002] In some high-temperature working conditions, such as when installing and disassembling the thermal field in a single crystal furnace, it is necessary to install and disassemble some fasteners in the thermal field.

[0045] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of this application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0046] In view of the disassembly and assembly conditions of the single crystal furnace hot field, when disassembling and assembling the fasteners in the hot field, the high temperature environment makes it impossible for personnel to operate in close contact with the hot field. During the fastening process of the fasteners, they must be clamped in place first and then tightened; during the removal of the fasteners, they must be screwed up first and then taken out. The difficulty in both processes lies in the reliable clamping of the fasteners.

[0047] The prior art usually utilizes two pull rods hinged on the disassembly and assembly tool to respectively control the corresponding clamping parts to achieve the clamping operation of the fastener to be disassembled and assembled. However, this control method of controlling the corresponding clamping parts by two pull rods respectively has the problem of low synchronization of the two pull rods. It is possible that the two clamping parts have different opening and closing degrees and different clamping forces, which may easily cause unstable clamping or fastener falling. Therefore, the use effect of the existing disassembly and assembly tools is not good, and the disassembly and assembly requirements of fasteners in the hot field of the single crystal furnace cannot be met.

[0048] In this regard, the utility model provides a fastener disassembly and assembly mechanism for a single crystal furnace thermal field, which enables the fasteners of the single crystal furnace thermal field to be disassembled and assembled at a long distance, wherein the fasteners include bolts, screws, and the like.

[0049] See also Figure 1 and Figure 6 As shown, the fastener disassembly and assembly mechanism for the single crystal furnace thermal field provided by the embodiment of the utility model includes an outer sleeve 1, a center rod 2, a detachable cutter head 3 and a clamping assembly 4.

[0050] Among them, the center rod 2 is inserted into the outer sleeve 1, the first end of the center rod 2 protrudes from the first end of the outer sleeve 1, the detachable cutter head 3 is installed at the first end of the center rod 2, and the detachable cutter head 3 has a clamping portion that cooperates with the fastener to be disassembled and assembled. Rotating the center rod 2 can drive the detachable cutter head 3 to screw the fastener.

[0051] The clamping assembly 4 includes a first clamping jaw 41, a second clamping jaw 42, a transmission member and a pull rod 43. The transmission member is escalably disposed at the first end of the outer sleeve 1. The first clamping jaw 41 and the second clamping jaw 42 are respectively hinged on both sides of the transmission member and are located on both sides of the detachable cutter head 3. The pull rod 43 is hinged to the transmission member, and the pull rod 43 drives the transmission member to rise and fall, thereby driving the first clamping jaw 41 and the second clamping jaw 42 to open and close synchronously.

[0052] It can be seen that the first clamp 41 and the second clamp 42 can be controlled to open and close synchronously through the pull rod 43 and the transmission component, that is, one pull rod 43 triggers the synchronous opening and closing of the first clamp 41 and the second clamp 42, which can effectively ensure that the two clamps have the same degree of closing and the same clamping force, thereby improving the stability of clamping.

[0053] In particular, the detachable cutter head 3 can be replaced with a flat head, a cross head, a Pozidriv head, a star head, a square head, a hexagonal head, a Y-shaped head, etc. according to the model of the fastener.

[0054] As an embodiment, the transmission component includes a movable ring 44, a first connecting rod 45 and a second connecting rod 46. The movable ring 44 can be slidably mounted on the center rod 2. The movable ring 44 is arranged near the first end of the center rod 2. Specifically, a center hole 441 for the center rod 2 to pass through can be provided on the movable ring 44 so that the movable ring 44 can be slidably mounted on the center rod 2. Of course, the sliding of the movable ring 44 relative to the center rod can also be achieved through external connecting parts such as sliding plates.

[0055] The pull rod 43 is hinged to the movable ring 44; the first clamping jaw 41 is provided with a first hinge point 411 and a second hinge point 412 at intervals, the second clamping jaw 42 is provided with a third hinge point 421 and a fourth hinge point 422 at intervals, and the first end of the outer sleeve 1 is provided with a fifth hinge point 121 and a sixth hinge point 122 symmetrically with the center rod 2 as the axis. The first clamping jaw 41 and the second clamping jaw 42 are respectively hinged to the movable ring 44 symmetrically with the center rod 2 as the axis through the first hinge point 411 and the third hinge point 421. Specifically, the movable ring 44 is provided with side wings 442 for mounting the first hinge point 411 and the third hinge point 421 on both sides, or a mounting plate for mounting with the first hinge point 411 and the third hinge point 421 is fixedly provided on both sides of the movable ring 44. The two ends of the first connecting rod 45 are respectively hinged to the first clamping jaw 41 and the outer sleeve 1 through the second hinge point 412 and the fifth hinge point 121. The two ends of the second connecting rod 46 are respectively hinged to the second clamping jaw 42 and the outer sleeve 1 through the fourth hinge point 422 and the sixth hinge point 122. The pull rod 43 drives the movable ring 44 to rise and fall along the central rod 2, thereby driving the first connecting rod 45 and the second connecting rod 46 to control the first clamping jaw 41 and the second clamping jaw 42 to open and close synchronously.

[0056] For details on the transmission process, see Figure 2 :

[0057] When the movable ring 44 is driven to rise by the pulling rod 43, the first hinge point 411 moves away from the fifth hinge point 121, and the first connecting rod 45 rotates upward around the fifth hinge point 121, pulling the first clamping jaw 41 to move toward the center around the first hinge point 411; similarly, the third hinge point 421 moves away from the sixth hinge point 122, and the second connecting rod 46 rotates upward around the sixth hinge point 122, pulling the second clamping jaw 42 to move toward the center around the third hinge point 421, thereby realizing the grasping action of the clamping assembly 4.

[0058] When the movable ring 44 is driven to descend, the first hinge point 411 approaches the fifth hinge point 121, and the first connecting rod 45 rotates downward around the fifth hinge point 121, pushing the first clamping jaw 41 to open outward around the first hinge point 411; similarly, the third hinge point 421 approaches the sixth hinge point 122, and the second connecting rod 46 rotates downward around the sixth hinge point 122, pushing the second clamping jaw 42 to open outward around the third hinge point 421, thereby realizing the release action of the clamping assembly 4.

[0059] It can be seen that the movable ring 44 is driven to rise and fall along the central rod 2 by the pull rod 43, driving the first connecting rod 45 and the second connecting rod 46 to swing, and then driving the first clamping jaw 41 and the second clamping jaw 42 to synchronously complete the clamping and releasing actions, which is convenient to operate and stable to clamp.

[0060] Furthermore, a slot 11 is provided at the first end of the outer sleeve 1, and the slot 11 extends along the axial direction of the outer sleeve 1. The pull rod 43 drives the movable ring 44 (when the movable ring 44 adopts an implementation scheme with a side wing portion, that is, its side wing portion 442) to rise and fall in the slot 11, thereby driving the first connecting rod 45 and the second connecting rod 46 to control the synchronous opening and closing of the first clamp 41 and the second clamp 42.

[0061] It can be seen that the slot 11 allows the movable ring 44 to only move axially along the center rod 2, avoiding displacement or rotation of the movable ring 44, and further improving the stability of the pull rod 43 driving the first clamp 41 and the second clamp 42 to open and close synchronously.

[0062] Optionally, an end cover 12 is fixedly mounted on the first end of the outer sleeve 1, and a fifth hinge point 121 hinged to the first connecting rod 45 and a sixth hinge point 122 hinged to the second connecting rod 46 can be arranged on the end cover 12, which is more convenient to install than arranging the fifth hinge point 121 and the sixth hinge point 122 on the outer sleeve 1.

[0063] Optionally, the fastener disassembly and assembly mechanism for the thermal field of the single crystal furnace further includes a holding assembly 5, which is configured to control the first clamping jaw 41 and the second clamping jaw 42 to be in an open state in a non-clamping state. Specifically, the holding assembly 5 includes a baffle 51 and a spring 52, the baffle 51 is fixedly arranged on the inner wall of the outer sleeve 1 or fixedly arranged on the center rod 2, and a spring 52 is arranged between the baffle 51 and the movable ring 44, where the spring 52 is used for reset, and the spring 52 is sleeved on the outer periphery of the center rod 2, and the two ends of the spring 52 abut against the baffle 51 and the movable ring 44 respectively.

[0064] It can be seen that through the cooperation of the baffle 51 and the spring 52, when the pull rod 43 is not operated, the spring 52 will squeeze the movable ring 44 downward, so that the first jaw 41 and the second jaw 42 are in an open state, thereby increasing the space between the first jaw 41 and the second jaw 42 when the detachable tool head on the center rod 2 is docked with the fastener, preventing the first jaw and the second jaw from interfering with the docking process.

[0065] As an embodiment, the fastener disassembly and assembly mechanism for the thermal field of the single crystal furnace also includes an operating rod 6 and a handle 7. The operating rod 6 is rotatably connected to the outer wall of the outer sleeve 1, and the pull rod 43 extends from the hinge with the transmission component to the second end of the outer sleeve 1 and is hinged to the operating rod 6; the handle 7 is fixedly arranged at the second end of the outer sleeve 1, and the handle 7 is located directly above the operating rod 6.

[0066] It can be seen that by providing the operating rod 6 and the handle 7, when it is necessary to clamp the bolt, the grip 7 is held and the operating rod 6 is pulled upward to complete the clamping action, which saves effort and time and is convenient for workers to operate.

[0067] In particular, a limit block 13 is provided on the outer sleeve 1 to limit the lifting stroke of the movable ring 44 .

[0068] It can be seen that the limit block 13 is used to prevent the movable ring 44 from excessive upward travel, that is, to limit the maximum clamping degree of the first clamping jaw 41 and the second clamping jaw 42, so as to maintain a moderate clamping force and avoid excessive clamping.

[0069] As an implementation manner, hooks 47 are respectively provided at the ends of the first clamping jaw 41 and the second clamping jaw 42 , and the hooks 47 are configured to hook the fastener to be disassembled.

[0070] It can be seen that the fasteners can be clamped more accurately by the hook 47, and for fasteners of different specifications, the adaptability of the disassembly and assembly mechanism can be increased by replacing the hooks 47 in different forms.

[0071] As an implementation manner, the fastener disassembly and assembly mechanism for the single crystal furnace thermal field further includes a ratchet wrench 8 adapted to the second end of the center rod 2 .

[0072] It can be seen that by rotating the ratchet wrench 8, the center rod 2, the detachable cutter head 3 and the fastener can be rotated, the required operating space is small, and the operator's hands do not need to be exposed above the heat field (in Figure 3 It can be operated from the side of the medium heat field), which is safer, convenient for one-handed operation and easy to operate.

[0073] As an implementation mode, the fastener disassembly and assembly mechanism for the single crystal furnace thermal field also includes a motor and a cylinder, the output end of the motor is drivingly connected to the second end of the center rod 2, and the driving end of the cylinder is drivingly connected to the pull rod 43.

[0074] It can be seen that the disassembly and assembly mechanism of the present application has a mechanism connected to the motor and cylinder transmission. By driving the central rod 2 to rotate through the motor and pulling the pull rod 43 through the cylinder, the bolts can be automatically disassembled and assembled, reducing labor input.

[0075] As an implementation mode, the detachable cutter head 3 is provided with an escape opening 31 for the first clamping jaw 41 and the second clamping jaw 42 to clamp the bolt.

[0076] It can be seen that by providing the avoidance opening 31 on the detachable cutter head 3 , the first clamping jaw 41 and the second clamping jaw 42 can conveniently clamp the bolt through the avoidance opening 31 .

[0077] It should be noted that the above-mentioned optional implementation modes can be combined in any combination, and the combined implementation modes all fall within the protection scope of this application.

[0078] Taking the disassembly and assembly of bolts in the thermal field of a single crystal furnace as an example, the following is combined with Figures 3 to 5 The disassembly and assembly principle under one implementation mode of the disassembly and assembly mechanism of the present application is introduced in detail:

[0080] Bolt installation in a hot field: 1) Select a detachable cutter head 3 that matches the head of the bolt 9 to be installed and fix it on the first end of the center rod 2; 2) After the detachable cutter head is engaged with the bolt 9 to be installed, pull the operating rod 6 upward toward the handle 7. Driven by the pull rod 43 and the transmission component, the first clamp 41 and the second clamp 42 approach the bolt 9, and the hooks arranged thereon hook the head of the bolt 9 to complete the clamping of the bolt 9; 3) Hold the handle 7 and the operating rod 6, maintain the relative position of the handle 7 and the operating rod 6, that is, the clamping state of the first clamp 41 and the second clamp 42, and place the bolt 9 in the bolt mounting hole in the hot field; 4) Loosen the handle 7 and the operating rod 6 to allow a sufficient distance between the first clamp 41 and the second clamp 42, and rotate the ratchet handle 8 until the bolt 9 is completely screwed into the bolt mounting hole.

[0081] The above embodiments are only to illustrate the basic principles and characteristics of the present application. The present application is not limited by the above embodiments.
