[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0042] like Figure 1As shown, an embodiment of the utility model provides a cutting device, which includes a base 10, a fixing assembly 20 and a cutting assembly 30. The fixing assembly 20 is movably arranged on the base 10, and the fixing assembly 20 can move along the extension direction of the base 10. The fixing assembly 20 is provided with a fixing structure 21, and the fixing structure 21 is used to fix the rubber ring. The cutting assembly 30 includes a support frame 31 and a cutting structure 32, the support frame 31 is fixed on the base 10, and the cutting structure 32 is rotatably arranged on the support frame 31, and the cutting structure 32 is arranged opposite to the fixing structure 21, and the cutting structure 32 is used to cut the rubber ring.

[0043] According to the technical solution of the present application, the rubber ring is fixed on the fixed structure 21, and the fixed assembly 20 can move along the extension direction of the base 10, the support frame 31 of the cutting assembly 30 is fixed on the base 10, and the cutting structure 32 of the cutting assembly 30 is rotatably arranged on the support frame 31. The cutting structure 32 can cut the rubber ring on the fixed structure 21 during the rotation process. In addition, the fixed structure 21 can change the cutting depth of the cutting structure 32 during the movement process. Therefore, by adopting the above structure, the redundant part inside the rubber ring can be cut off, thereby completing the modification of the inner diameter of the rubber ring. In addition, the cutting structure 32 cuts the inside of the rubber ring during the rotation process, which can ensure the flatness of the cutting surface and avoid the serration of the inside of the rubber ring due to manual operation, so that the rubber ring meets the underground electrical use standards and avoids the waste of the rubber ring due to unqualified cutting. At the same time, the cutting structure 32 is used to cut the rubber ring, which can increase the cutting speed, thereby improving the processing efficiency of the rubber ring and reducing the processing difficulty of the rubber ring.

[0044] Among them, in the prior art, when workers use vulcanized knives, needle-nosed pliers, screwdrivers and other devices for manual cutting, workers are very likely to be cut. However, in the present application, the rubber ring is fixed on the fixed structure 21, and the workers only need to drive the cutting structure 32 to rotate and drive the fixed component 20 to move. Such a setting can prevent workers from being injured and ensure the personal health of the workers.

[0045] Furthermore, the cutting device also includes a driving assembly 40, which is arranged on a side of the fixed assembly 20 away from the cutting assembly 30. The driving assembly 40 has a driving end 421, which is fixedly connected to the fixed assembly 20 to drive the fixed assembly 20 to move along the extension direction of the base 10.

[0046] Such an arrangement makes it easier for the staff to drive the fixing component 20 to move, thereby reducing the difficulty in driving the fixing component 20 to move.

[0047] Specifically, the fixing structure 21 includes a chuck body 211, a plurality of claws 212 and a support member 213. The plurality of claws 212 are distributed at intervals along the circumference of the chuck body 211, and the claws 212 can move along the radial direction of the chuck body 211, and the plurality of claws 212 cooperate to clamp the rubber ring. The support member 213 is arranged on the claws 212, and the support member 213 is used to support the rubber ring.

[0048] With such arrangement, the claw 212 can accurately fix the rubber ring, ensuring accuracy and repeatability during the processing. The support member 213 can further ensure stability during the fixing process of the rubber ring, preventing the rubber ring from falling off or being displaced during the clamping process.

[0049] Furthermore, a slide groove is provided on the chuck body 211 , and the slide groove extends along the radial direction of the chuck body 211 , and the claw 212 is slidably disposed in the slide groove.

[0050] With such arrangement, the clamping claw 212 can quickly clamp and release the rubber ring, thereby shortening the time required for placing the rubber ring and improving processing efficiency.

[0051] The support member 213 has an arc-shaped structure, which can reduce the deformation of the rubber ring when it is fixed, and further ensure the flatness of the inside of the rubber ring when it is cut.

[0052] Specifically, in the present application, the support member 213 is an arc-shaped plate, and the staff directly places the rubber ring on the support member 213 when fixing the rubber ring.

[0053] Among them, in the actual production process, the maximum outer diameter of the rubber ring is 125mm and the minimum inner diameter is 40mm. In this application, the diameter of the support member 213 is 125mm. In this way, when the support member 213 supports a rubber ring smaller than 125mm, each support member 213 and the rubber ring have two supporting points, which can further ensure the supporting effect of the support member 213 on the rubber ring.

[0054] Furthermore, the cutting assembly 30 also includes a transmission structure 33 and an operating rod 34. The transmission structure 33 is fixed on the support frame 31, and the transmission structure 33 has an operating end and a mounting end that are relatively arranged, and the cutting structure 32 is fixed on the mounting end. The operating rod 34 is fixedly connected to the operating end, and drives the cutting structure 32 to rotate through the transmission structure 33.

[0055] With such arrangement, the worker can drive the operating rod 34 to rotate, thereby driving the cutting structure 32 to rotate through the connection between the operating rod 34 and the transmission structure 33, which is easy to operate. At the same time, the worker can stay away from the cutting structure 32 to avoid being hurt.

[0056] Specifically, in the present application, the transmission structure 33 is a planetary reducer, the operating end is the input end, and the installation end is the output end.

[0057] The cutting structure 32 includes a fixing block 321, a cutter 322 and a locking member 323. The fixing block 321 is fixed to the mounting end, and the fixing block 321 is provided with a mounting hole and a locking hole that are interconnected. The cutter 322 is slidably arranged in the mounting hole. The locking member 323 is inserted into the locking hole to fix the cutter 322. Such a setting facilitates the installation of the cutter 322, has a simple structure, and is easy to operate.

[0058] Specifically, the tool 322 has a handle, which can be slidably inserted into the mounting hole. The locking piece 323 is threadedly connected to the locking hole. When the tool 322 moves to the desired position, the locking piece 323 abuts against the handle and fixes the tool 322 in the mounting hole. When the tool 322 needs to change its position, it only needs to loosen the locking piece 323.

[0059] Furthermore, the cutter 322 has a cutter head 3221, and the cross-sectional area of ​​the cutter head 3221 gradually decreases along the extension direction. This arrangement can make the cutter head 3221 sharper, thereby facilitating the cutter head 3221 to cut the rubber ring, and can prevent the cutter head 3221 from breaking.

[0060] Specifically, the cutter head 3221 is a triangular pyramid structure.

[0061] The fixing assembly 20 further includes a fixing frame 22, a guide groove 11 is provided on the base 10, the guide groove 11 extends along the extension direction of the base 10, the bottom of the fixing frame 22 is slidably arranged in the guide groove 11, and the driving assembly 40 is drivingly connected to the fixing frame 22. Such a setting can ensure the accuracy of the fixing frame 22 during movement, avoid the fixing frame 22 from being deflected during movement, and thus ensure the accuracy of the cutting structure 32 during cutting.

[0062] Specifically, the base 10 is fixed to the working surface by bolts.

[0063] Furthermore, the driving assembly 40 includes a mounting seat 41 and a screw 42. The mounting seat 41 is arranged on a side of the fixing frame 22 away from the cutting assembly 30. The screw 42 is threadedly matched with the mounting seat 41, and the screw 42 has a driving end 421. With such a configuration, the structure is simple, and the driving assembly 40 is easy to assemble, and the fixing frame 22 can be driven to move accurately. At the same time, the driving assembly 40 can also fix the fixing frame 22 to prevent the fixing frame 22 from being displaced after it is moved into place.

[0064] A handle 422 is provided at the other end of the screw rod 42 , and the staff drives the screw rod 42 to rotate through the handle 422 . This arrangement makes it easy for the staff to drive the screw rod 42 to rotate, and further facilitates driving the fixing frame 22 to move.

[0065] Specifically, due to explosion-proof requirements when working underground in coal mines, however, in the present application, the drive assembly 40 and the cutting assembly 30 are both manually controlled, and explosion-proof issues do not need to be considered during operation. This can simplify the structure of the cutting device and ensure the safety of the staff when using the cutting device.

[0066] Among them, the specific use of the cutting device is:

[0067] 1. Fix the rubber ring on the support member 213;

[0068] 2. The fixing frame 22 is driven to move on the base 10 by the driving assembly 40 so that the cutter head 3221 contacts the rubber ring;

[0069] 3. The tool 322 is driven to rotate by the operating rod 34.

[0070] During the cutting process, the staff can drive the fixed frame 22 to move according to the needs.

[0071] At the same time, using the above structure:

[0072] Reduce the risk of injury to operators when using vulcanizing knives, and improve the flatness of the inside of the rubber ring;

[0073] Solve the problem of misfire caused by non-standard rubber ring production by staff;

[0074] It greatly shortens the time of rubber ring production and improves work efficiency.

[0075] Improve the standardization of rubber ring processing, so that the finished rubber rings are more in line with the operating standard requirements, avoiding traditional manual processing errors and waste.
