Description

Technical Field

[0001] This utility model relates to the field of special fixture technology, specifically a special fixture for high load-bearing bevel gears with noise reduction capability. Background Technology

[0002] Bevel gears, also known as conical gears, are used for transmission between intersecting shafts. Compared with cylindrical gears, they can change the direction of transmission. During the drilling process of bevel gears, if the fixture does not hold the bevel gear tightly enough, the workpiece will move, shake, or vibrate under the action of the machining force. This irregular movement will cause the cutting force between the tool and the workpiece to be unstable, thus generating vibration and noise.

[0003] The stability of bevel gear clamping is closely related to the choice of clamping position. Since bevel gears have gears, there is a large space in some areas, which makes it difficult to choose a reasonable clamping position. Taking the common chuck structure as an example, the chuck teeth can usually only move in a straight line, making it difficult to flexibly choose a suitable clamping position. Therefore, during the processing, the workpiece is very easy to slip due to improper clamping position, which in turn causes a series of problems such as noise. To this end, this application proposes a special clamp for bevel gears with high load-bearing capacity that can reduce noise. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a high-load-bearing bevel gear special clamp with noise reduction capability, including a chuck in which a bevel gear is movably installed, and a fixing component, which includes a support frame, a clamping tooth, a support screw, a sliding sleeve, a connecting frame, a lifting plate, a lifting cylinder, and a clamping bracket.

[0005] The chuck is rotatably connected to the support frame, the chuck teeth are movably installed on the side of the support frame, the support screw is rotatably connected to the support frame, the sliding sleeve is threadedly connected to the support screw, one end of the connecting frame is movably connected to the sliding sleeve, and the other end of the connecting frame is movably connected to the chuck teeth, the lifting plate is fixedly connected to the lower end of the sliding sleeve, the lifting cylinder is fixedly connected to the support frame, and the chuck bracket is fixedly connected to the output shaft of the lifting cylinder, and the chuck bracket is slidably connected to the lifting plate.

[0006] In some embodiments, the chuck has a placement slot, and the bevel gear is movably mounted in the placement slot of the chuck.

[0007] In some embodiments, the fixing assembly further includes a first bearing and a third bearing, the chuck is movably mounted to the support frame via the first bearing, and the lower end of the support screw is rotatably connected to the support frame via the third bearing.

[0008] In some embodiments, the fixing assembly further includes a first movable slot and a rotating rod. The first movable slot is formed on the support frame, the rotating rod is fixedly connected in the first movable slot, the locking tooth is rotatably connected to the rotating rod, and a rubber pad is fixedly connected to the upper end of the locking tooth.

[0009] In some embodiments, the fixing assembly further includes a second bearing, which is movably mounted on the outer side of the sliding sleeve, and one end of the connecting bracket is fixedly connected to the second bearing.

[0010] In some embodiments, the fixing component further includes a second movable slot, which is formed on the retaining tooth, and the connecting bracket is movably installed in the second movable slot.

[0011] In some embodiments, the fixing assembly further includes a positioning hole, a positioning bolt, and a mounting plate. The positioning hole is located on the outer side of the chuck, the positioning bolt is movably mounted on the support frame, and the mounting plate is fixedly connected to the lower end of the support frame.

[0012] This utility model has at least the following beneficial effects:

[0013] A fixing component is installed below the chuck. The friction between the chuck holder and the lifting plate is increased by anti-slip pads and other structures, resulting in a large friction between them. When the positioning bolt is loosened, the sliding sleeve moves synchronously as the lifting plate moves up and down, causing the support screw to rotate. The chuck rotates within the support frame, thus selecting the clamping position for the bevel gear. Once a suitable position is selected, the positioning bolt is tightened to restrict further rotation of the chuck. At this time, the lifting plate moves downward, and the upper ends of the chuck teeth close together, thus fixing and clamping the bevel gear. By clamping the teeth in a reasonable position, avoiding excessive space at the contact point, the clamping is more stable and less prone to slippage during processing, thereby avoiding excessive noise.

[0021] 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.

[0022] Example 1:

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a high-load-bearing bevel gear special clamp with noise reduction, including a chuck 1, in which a bevel gear 2 is movably installed, and also includes a fixing component 3, which includes a support frame 301, a clamping tooth 303, a support screw 307, a sliding sleeve 308, a connecting frame 310, a lifting plate 311, a lifting cylinder 314, and a clamping bracket 315;

[0024] The chuck 1 is rotatably connected to the support frame 301. The chuck tooth 303 is movably installed on the side of the support frame 301. The support screw 307 is rotatably connected to the support frame 301. The sliding sleeve 308 is threadedly connected to the support screw 307. One end of the connecting frame 310 is movably connected to the sliding sleeve 308, and the other end of the connecting frame 310 is movably connected to the chuck tooth 303. The chuck 1 has a placement groove 4, and the bevel gear 2 is movably installed in the placement groove 4 of the chuck 1.

[0025] Furthermore, the fixing component 3 also includes a first movable groove 302 and a rotating rod 304. The first movable groove 302 is opened on the support frame 301, the rotating rod 304 is fixedly connected in the first movable groove 302, and the locking tooth 303 is rotatably connected to the rotating rod 304. A rubber pad is fixedly connected to the upper end of the locking tooth 303.

[0026] The clevis 303 has a rotating hole at the position corresponding to the rotating rod 304. The clevis 303 rotates on the rotating rod 304. When the upper end of the clevis 303 closes, it fixes the bevel gear 2. When the upper end of the clevis 303 opens, it releases the bevel gear 2.

[0027] Furthermore, the fixing component 3 also includes a second bearing 309, which is movably mounted on the outside of the sliding sleeve 308, and one end of the connecting bracket 310 is fixedly connected to the second bearing 309.

[0028] The second bearing 309 is located on the side of the sliding sleeve 308, so that the sliding sleeve 308 can be connected to the connecting frame 310.

[0029] Furthermore, the fixing component 3 also includes a second movable slot 305, which is formed on the retaining tooth 303, and the connecting bracket 310 is movably installed in the second movable slot 305.

[0030] The lower part of the locking tooth 303 is inclined inward, and the second movable groove 305 is opened at the lower part of the locking tooth 303. The connecting frame 310 is movably installed in the second movable groove 305 of the locking tooth 303.

[0031] When the sliding sleeve 308 moves upward, the connecting frame 310 moves upward in the second movable groove 305 of the locking tooth 303, causing the locking tooth 303 to open outward through the rotating rod 304, thereby releasing the clamped bevel gear 2. When the sliding sleeve 308 moves downward, the connecting frame 310 moves downward in the second movable groove 305, causing the locking tooth 303 to rotate inward through the rotating rod 304, causing the upper ends of the locking teeth 303 to close together, thereby clamping the bevel gear 2 and keeping the bevel gear 2 fixed.

[0032] Example 2:

[0033] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6Based on Embodiment 1, this utility model provides another technical solution: the fixing component 3 further includes a first bearing 306 and a third bearing 312. The chuck 1 is movably installed with the support frame 301 through the first bearing 306. The lower end of the support screw 307 is rotatably connected with the support frame 301 through the third bearing 312. The lifting plate 311 is fixedly connected to the lower end of the sliding sleeve 308. The lifting cylinder 314 is fixedly connected inside the support frame 301, and the clamp 315 is fixedly connected to the output shaft of the lifting cylinder 314. The clamp 315 is slidably connected to the lifting plate 311. The fixing component 3 further includes a positioning hole 313, a positioning bolt 316, and a mounting plate 317. The positioning hole 313 is opened on the outer side of the chuck 1. The positioning bolt 316 is movably installed on the support frame 301. The mounting plate 317 is fixedly connected to the lower end of the support frame 301.

[0034] The up-and-down movement of the sliding sleeve 308 causes the clamping teeth 303 to open outward or clamp the bevel gear 2 inward. The lifting cylinder 314 pushes the clamping bracket 315 up and down, thereby providing power for the up-and-down movement of the lifting plate 311. The clamping bracket 315 is slidably connected to the lifting plate 311. An anti-slip pad is fixedly connected inside the clamping bracket 315. There is a large friction between the clamping bracket 315 and the lifting plate 311. After loosening the positioning bolt 316, the positioning bolt 316 moves out of the corresponding positioning hole 313 on the chuck 1. At this time, the sliding sleeve 308 moves up and down. Through the connection between the screw hole at the center of the sliding sleeve 308 and the support screw 307, the support screw 307 rotates. The upper end drives the chuck 1 to rotate, causing the bevel gear 2 in the placement slot 4 to rotate synchronously, thereby changing the clamping position. When a suitable position is selected, the positioning bolt 316 is tightened, so that one end of the positioning bolt 316 is inserted into the corresponding positioning hole 313, thus limiting the chuck 1 and making it difficult to continue rotating. At this time, the clamping bracket 315 moves up and down. Since the chuck 1 cannot move, the support screw 307 is fixed and cannot rotate. The sliding sleeve 308 starts to rotate, and the lifting plate 311 rotates synchronously, resulting in greater friction in the clamping bracket 315. Through this structure, the clamping position is selected, so that the bevel gear 2 is clamped securely, avoiding insufficient clamping during processing, which could cause slippage and generate significant noise.
