Description

Technical Field

[0001] The utility model relates to the technical field of ovens, and particularly to a quick clamping structure for parts of an oven. Background Art

[0002] The voice coil is an important part of a loudspeaker. During its manufacturing process, some insulating materials or glues need to be coated. Baking the voice coil can quickly cure these materials to ensure the performance and stability of the voice coil;

[0003] The voice coil bobbin is the support structure of the voice coil. It is in the shape of a hollow cylinder to allow a magnetic field to be generated when an electric current passes through the voice coil, interact with the permanent magnet in the loudspeaker, and thus drive the diaphragm to vibrate and produce sound.

[0004] In the prior art, a certain number of voice coil bobbins are generally placed inside a containing vessel and then directly placed inside an oven for baking. If, during the placement process or when placed inside the oven, the voice coil bobbins are stacked due to collision or the tilting of the vessel, and if discovered in time, they need to be manually rearranged. If not discovered in time and directly baked, when there is glue or other sticky substances on the surface of the voice coil bobbins, the adjacent bobbins will stick to each other at high temperature and be difficult to separate, resulting in product damage. At the same time, the voice coil bobbins block each other, and heat is difficult to evenly transfer to each bobbin. The inner bobbins may be insufficiently heated, affecting the curing effect, while the outer bobbins may be locally overheated, resulting in damage to the material properties. Moreover, due to the high temperature of the voice coil bobbins after baking, they are not easy to disassemble.

[0005] Therefore, the utility model provides a quick clamping structure for parts of an oven that can support the voice coil bobbin and quickly fix and disassemble it. Summary of the Utility Model

[0006] A quick clamping structure for parts of an oven is designed to address the problem of the inconvenience of fixing and disassembling the voice coil bobbin in the prior art.

[0007] The technical solution adopted by the utility model to solve its technical problems is: a quick clamping structure for parts of an oven, including two support plates and a bottom plate. The bottom plate is arranged inside the two support plates and is assembled to provide support for the clamping component. A collecting plate is arranged on the top of the bottom plate and is assembled to remove the voice coil bobbin by squeezing the clamping component.

[0008] Further, four threaded holes are respectively formed through the opposite sides of the two support plates.

[0009] Further, the bottom plate is installed inside the two support plates. Ventilation holes are formed at the top of the bottom plate, and two through holes are formed at the top of the bottom plate. The ventilation holes are located on one side close to the two through holes. Four hollow rings are installed at the top of the bottom plate, and four fixed columns are installed at the top of the bottom plate. The four fixed columns are respectively located inside the four hollow rings.

[0010] Further, a collection plate is placed on the tops of the four hollow rings, and the collection plate is sleeved outside the four fixed columns. A round hole is formed through the top of the collection plate, and two side holes are formed at the top of the collection plate. The round hole is located on one side where the two side holes are close to each other.

[0011] Further, a protective frame is installed at the top of the collection plate.

[0012] Further, a clamping component is arranged on the top of the bottom plate and is assembled to fix the voice coil skeleton to be baked. The clamping component includes two support plates installed on the top of the bottom plate. A square column is installed inside the two support plates. Round grooves are formed at the top and bottom of the square column. Tightening plates are installed on one side close to each other of the two round grooves through springs, and one side of each tightening plate close to the square column is connected to one side close to each other of the two round grooves through a spring. A limiting ring is installed on one side of each tightening plate close to the square column, and the limiting ring is located inside the round groove.

[0013] Further, the clamping component further includes two movable rings installed on both sides of the square column. Movable columns are placed inside the two movable rings. A top plate is installed at one end of each movable column away from the square column. A top beam rod is rotatably installed at the top of each top plate. The other end of each top beam rod is rotatably installed on both sides of the collection plate close to the top of the square column. A bottom beam rod is rotatably installed at the bottom of each top plate. The other end of each bottom beam rod is rotatably installed on both sides of the collection plate close to the bottom of the square column.

[0014] Advantages of the utility model:

[0015] (1) For the quick clamping structure of parts for an oven described in the utility model, a clamping component is adopted. When the voice coil skeleton is placed outside the clamping component, since the two springs always pull the two tightening plates to move towards the side close to the square column, the two movable rods are always pulled towards the side away from the square column, so that the two top plates support the outer voice coil skeleton, completing the fixed support of a single voice coil skeleton. It can not only simply and quickly support the voice coil skeleton, but also ensure that each voice coil skeleton has the same baking area, improving the baking efficiency.

[0016] (2) The quick clamping structure for parts of an oven according to the present utility model uses a collecting plate and round holes. Since the diameter of the round holes is smaller than the inner diameter of the voice coil skeleton, when the collecting plate presses the clamping assembly, the clamping assembly will be separated from the voice coil skeleton. After the collecting plate completely moves to the top of the square column and the tightening plate, all the baked voice coil skeletons are removed from the outside of the clamping assembly. Under the action of the protective frame, the voice coil skeletons will not fall off from the top of the collecting plate and are concentrated inside the protective plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0025] Embodiment:

[0026] As Figures 1-5 shown, a quick clamping structure for parts of an oven according to the present utility model includes two support plates 11, a bottom plate 2 disposed inside the two support plates 11 and assembled to provide support for the clamping assembly 5, and a collecting plate 3 disposed on the top of the bottom plate 2 and assembled to remove the voice coil skeleton by pressing the clamping assembly 5.

[0027] Preferably, four threaded holes 12 are formed through the opposite sides of the two support plates 11.

[0028] In this embodiment, before use, the staff fixes one of the support plates 11 by passing four bolts through the inner sides of the four threaded holes 12 and fixing them to the inner side of the oven. Then, the other support plate 11 is fixed using the same steps, so that the two support plates 11 firmly support the entire clamping structure inside the oven, preparing for the subsequent work.

[0029] Preferably, the clamping assembly 5 is arranged on the top of the bottom plate 2 and is assembled to fix the voice coil skeleton to be baked. The clamping assembly 5 includes two support plates 51, the two support plates 51 are installed on the top of the bottom plate 2, a square column 52 is installed inside the two support plates 51, circular grooves 521 are formed at the top and bottom of the square column 52, tightening plates 58 are installed on the adjacent sides of the two circular grooves 521 through springs, and one side of each tightening plate 58 close to the square column 52 is connected to the adjacent side of the two circular grooves 521 through a spring. A limiting ring 59 is installed on one side of each tightening plate 58 close to the square column 52, and the limiting ring 59 is located inside the circular groove 521.

[0030] Preferably, the clamping assembly 5 further includes two movable rings 53, the two movable rings 53 are installed on both sides of the square column 52, movable columns 54 are placed inside the two movable rings 53, a top plate 55 is installed at one end of each movable column 54 away from the square column 52, a top beam rod 56 is rotatably installed on the top of each top plate 55, the other end of each top beam rod 56 is rotatably installed on both sides of the collecting plate 3 close to the top of the square column 52, a bottom beam rod 57 is rotatably installed on the bottom of each top plate 55, and the other end of each bottom beam rod 57 is rotatably installed on both sides of the collecting plate 3 close to the bottom of the square column 52.

[0031] In this embodiment, several sets of snap - on voice coil skeletons are provided. When snap - on the voice coil skeleton, the staff vertically places the voice coil skeleton on the top of the square column 52 by hand, and keeps the voice coil skeleton and the square column 52 in the same vertical direction. Then, the voice coil skeleton is moved towards the side close to the bottom plate 2. The bottom of the voice coil skeleton presses two top beam rods 56, and the two top beam rods 56 conduct the force to two top plates 55 and the tightening plate 58 at the top of the square column 52. The two top plates 55 push two movable columns 54 into the inner sides of two movable rings 53. The tightening plate 58 at the top of the square column 52 stretches the spring and moves towards the side away from the square column 52. The limiting ring 59 can ensure that the collecting plate 3 moves horizontally along the vertical direction. The two fixed plates push the tightening plate 58 at the bottom of the square column 52 towards the side away from the square column 52 through two bottom beam rods 57. When the two top plates 55 are located in the middle of the inner side of the voice coil skeleton, stop moving the voice coil skeleton. Since the two springs inside the square column 52 are stretched, the two springs always pull the two tightening plates 58 towards the side close to the square column 52. Then, through the two top beam rods 56 and two bottom connecting rods, the two movable rods are always pulled towards the side away from the square column 52. The two movable rods push the two top plates 55 towards the side away from the square column 52. The two top plates 55 support the outer voice coil skeleton, completing the fixed support for a single voice coil skeleton. Then, use the same method to sleeved the remaining voice coil skeletons on the outer sides of the two top plates 55 of the remaining snap - on components 5 one by one. This can not only simply and quickly support the voice coil skeleton, but also ensure that the baking area of each voice coil skeleton is the same, improving the baking efficiency.

[0032] Preferably, the bottom plate 2 is installed inside two support plates 11. Ventilation holes 21 are opened at the top of the bottom plate 2. Two through holes 22 are opened at the top of the bottom plate 2, and the ventilation holes 21 are located on the side close to the two through holes 22. Four hollow rings 23 are installed at the top of the bottom plate 2. Four fixed columns 24 are installed at the top of the bottom plate 2, and the four fixed columns 24 are respectively located inside the four hollow rings 23.

[0033] Preferably, a collecting plate 3 is placed on the top of the four hollow rings 23, and the collecting plate 3 is sleeved outside the four fixed columns 24. A round hole 31 is penetrated and opened at the top of the collecting plate 3. The number of the round holes 31 is the same as the number of the snap - on components 5. The diameter of the round hole 31 is smaller than the inner diameter of the voice coil skeleton and larger than the distance between the two ends of the two movable rings 53 away from each other. Two side holes 32 are opened at the top of the collecting plate 3, and the round hole 31 is located on the side close to the two side holes 32.

[0034] Preferably, a protective frame 4 is installed at the top of the collecting plate 3.

[0035] In this embodiment, the bottom plate 2 can support the support plate 11. The ventilation holes 21 can prevent poor baking quality caused by excessive heat concentration or uneven heat distribution. The four hollow rings 23 on the top of the bottom plate 2 are used to support the collection plate 3, and the four fixed columns 24 are used to limit the position and movement trajectory of the collection plate 3.

[0036] In specific operation, after baking is completed, after the staff wears heat-insulating gloves, one hand passes through one of the through holes 22 and the side holes 32 to pull the bottom plate 2 out from the inner sides of the two support plates 11. When the bottom plate 2 is about to be pulled out from the inner sides of the two support plates 11, the other hand passes through the other through hole 22 and the side hole 32 to move the bottom plate 2 and the collection plate 3 to a designated location after pulling them out from the inner sides of the support plates 11. Then, with the help of tools or another staff member, the bottom plate 2 is fixed. Then, the original staff member uses one hand to drive the collection plate 3 to move away from the bottom plate 2 through the two side holes 32. The collection plate 3 squeezes the two bottom beam rods 57 of each set of clamping components 5. The two bottom beam rods 57 transmit the force to the two top plates 55 and the tightening plate 58 at the bottom of the square column 52. The two top plates 55 push the two movable columns 54 into the inner sides of the two movable rings 53. The tightening plate 58 at the bottom of the square column 52 stretches the spring and moves away from the square column 52. The two fixed plates push the tightening plate 58 at the bottom of the square column 52 to move away from the square column 52 through the two bottom beam rods 57. Since the diameter of the round hole 31 is smaller than the inner diameter of the voice coil bobbin, the top plate 55 releases the fixation of the voice coil bobbin. The collection plate 3 continues to move away from the bottom plate 2. After the collection plate 3 completely moves to the top of the tightening plate 58 at the top of the square column 52, all the baked voice coil bobbins are removed from the outside of the clamping component 5. Under the action of the protective frame 4, the voice coil bobbins will not fall off from the top of the collection plate 3.

[0037] Working principle: The initial state refers to Figures 1-5, before use, the staff fixes one of the support plates 11 inside the oven by passing four bolts through the inside of the four threaded holes 12. Then, the other support plate 11 is fixed using the same steps, firmly supporting the entire clamping structure inside the oven. When clamping the voice coil skeleton, the staff vertically places the voice coil skeleton on the top of the square column 52 by hand and keeps the voice coil skeleton and the square column 52 in the same vertical direction. Then, the voice coil skeleton is moved towards the side close to the bottom plate 2. The bottom of the voice coil skeleton presses against the two top beam rods 56, and the two top beam rods 56 conduct the force to the two top plates 55 and the tightening plate 58 at the top of the square column 52. The two top plates 55 push the two movable columns 54 into the inside of the two movable rings 53. The tightening plate 58 at the top of the square column 52 stretches the spring and moves towards the side away from the square column 52. The two fixed plates push the tightening plate 58 at the bottom of the square column 52 towards the side away from the square column 52 through the two bottom beam rods 57. When the two top plates 55 are located in the middle inside the voice coil skeleton, stop moving the voice coil skeleton to complete the fixed support for a single voice coil skeleton. Then, the remaining voice coil skeletons are sleeved outside the two top plates 55 of the remaining clamping assemblies 5 in the same way one by one; after baking, after the staff wears heat-insulating gloves, one hand passes through one of the through holes 22 and the side hole 32 to pull the bottom plate 2 out from the inside of the two support plates 11. When the bottom plate 2 is about to be removed from the inside of the two support plates 11, the other hand passes through the other through hole 22 and the side hole 32 to move the bottom plate 2 and the collection plate 3 to a designated location after removing them from the inside of the support plates 11. Then, borrow tools or another staff member to fix the bottom plate 2. Then, the original staff member drives the collection plate 3 to move towards the side away from the bottom plate 2 by hand through the two side holes 32. The collection plate 3 presses against the two bottom beam rods 57 of each clamping assembly 5. The two bottom beam rods 57 conduct the force to the two top plates 55 and the tightening plate 58 at the bottom of the square column 52. The two top plates 55 push the two movable columns 54 into the inside of the two movable rings 53. The tightening plate 58 at the bottom of the square column 52 stretches the spring and moves towards the side away from the square column 52. The two fixed plates push the tightening plate 58 at the bottom of the square column 52 towards the side away from the square column 52 through the two bottom beam rods 57 to release the fixation of the voice coil skeleton. The collection plate 3 continues to move towards the side away from the bottom plate 2. After the collection plate 3 completely moves to the top of the tightening plate 58 at the top of the square column 52, all the baked voice coil skeletons are removed from the outside of the clamping assembly 5. Under the action of the protective frame 4, the voice coil skeletons are concentrated on the top of the collection plate 3.
