Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission, in particular to a claw-type coupling mechanism. Background Art

[0002] Existing couplings often fail to effectively absorb vibration and reduce impact.

Furthermore, securing components such as the bayonet pin are prone to axial displacement, compromising the coupling's operational stability, and lack effective retaining mechanisms to ensure accurate positioning. Existing buffer structures often require complete replacement, making it difficult to easily repair localized damage, impacting both maintenance efficiency and the equipment's service life.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] According to an embodiment of the present utility model, a claw-type coupling mechanism is provided.

[0024] Embodiment 1;

[0025] like Figure 1-9 As shown, the claw-type coupling mechanism according to the embodiment of the present invention includes a claw structure 1, which includes a coupling block 101, four claws 102, a docking groove 103, a docking block 104, a coupling cavity 105, and a pin groove 106. Four claws 102 are integrated on one side of the coupling block 101, and a docking groove 103 is formed between the four claws 102. A docking block 104 is provided on one side of the coupling block 101, and a coupling cavity 105 is provided on the inner side of the coupling block 101. A pin groove 106 is opened on one side of the coupling cavity 105, and one side of the coupling cavity 105 is rotatably connected to a limiting structure 3. The docking groove 103 is docked with a buffer structure 4, and the buffer structure 4 is installed on the connecting structure 2. The coupling block 101 is docked with the docking block 104 by bolts.

[0026] The docking shafts are respectively docked in the coupling cavities 105 of the two sets of coupling blocks 101. The two sets of docking coupling blocks 101 are docked through the docking grooves 103. The docking grooves 103 are also docked with a buffer structure 4. The buffer structure 4 is fixedly installed through the connecting structure 2. The buffer structure 4 and the connecting structure 2 form a buffer colloid. The buffer colloid is used to absorb vibration, reduce impact loads and compensate for misalignment between shafts. Since the docking of the buffer structure 4 and the connecting structure 2 is a detachable design, when a specific buffer structure 4 is severely damaged, it can be disassembled and replaced separately, which improves convenience and reduces the frequency of replacement of the entire buffer colloid.

[0027] The limiting structure 3 includes a limiting baffle 301, a hinge 302, a buffer groove 303, a sliding block 304, a limiting block 305, a connecting groove 306, a limiting slide 307, and a buffer spring 308. The limiting baffle 301 is connected to the hinge 302, and the limiting baffle 301 is rotatably connected to the coupling block 101 through the hinge 302. A buffer groove 303 is provided on the limiting baffle 301, and a limiting slide 307 is provided in the buffer groove 303. The limiting slide 307 is slidably connected to the sliding block 304. Both ends of the sliding block 304 are fixedly connected to the limiting block 305. A connecting groove 306 is provided on one side of the sliding block 304. A buffer spring 308 is installed on the buffer groove 303, and the buffer spring 308 is connected to the connecting groove 306.

[0028] When the shaft is connected, it is generally positioned by a pin, which is generally installed on the pin groove 106, and the sliding block 304 of the limit baffle 301 is located at the end of the pin, which can play an axial limiting role on the pin to prevent the pin from producing a large axial displacement. The sliding block 304 is limited and slides in the limiting slide groove 307 by the limit block 305, and is buffered by the buffer spring 308. A threaded hole is provided on the limit baffle 301, and the limit baffle 301 is fixedly connected to the coupling block 101 by inserting a bolt through the threaded hole. The rotating connection of the limit baffle 301 and the convenient fixed connection design can limit the pin axially without affecting the installation of the pin and the disassembly of the coupling.

[0029] The connecting structure 2 includes a connecting ring 201, a docking surface 202, a docking slot 203, and a docking threaded hole 204. The outer ring of the connecting ring 201 is provided with a docking surface 202, a docking slot 203 is opened on the docking surface 202, and docking threaded holes 204 are opened on both sides of the docking slot 203 on the docking surface 202.

[0030] The buffer structure 4 includes a metal frame 401, a rubber sleeve 402, an introduction groove 403, a docking hole 404, a positioning block 405, and a disassembly slot 406. The outer ring of the metal frame 401 is sleeved with the rubber sleeve 402, an introduction groove 403 is opened in the metal frame 401, and a docking hole 404 is opened at the bottom of the introduction groove 403. One end of the metal frame 401 is fixedly connected with a positioning block 405, and the introduction groove 403 is matched with a disassembly slot 406, and the docking hole 404 matches the docking threaded hole 204.

[0031] The rubber sleeve 402 outside the metal frame 401 is the main buffer colloid. The metal frame 401 is first positioned in the docking slot 203 of the connecting structure 2 through the positioning block 405, and then the bolts are inserted into the docking hole 404 and the docking threaded hole 204 for fixed docking. When the metal frame 401 needs to be disassembled, the bolts are first removed, and then the disassembly rod with a bent hook is introduced into the disassembly slot 406 through the introduction slot 403, and then the metal frame 401 can be pulled out together with the rubber sleeve 402 for separate replacement without disassembling the claw structure 1, thereby improving the replacement efficiency of the buffer colloid.

[0032] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0033] In the actual process, the docked shafts are respectively docked in the coupling cavities 105 of the two sets of coupling blocks 101. The two sets of docked coupling blocks 101 are docked through the docking grooves 103. The docking grooves 103 are also docked with a buffer structure 4. The buffer structure 4 is fixedly installed through the connecting structure 2. The buffer structure 4 and the connecting structure 2 form a buffer colloid. The buffer colloid is used to absorb vibration, reduce impact loads and compensate for misalignment between shafts. Since the docking of the buffer structure 4 and the connecting structure 2 is a detachable design, when a specific buffer structure 4 is seriously damaged, it can be disassembled and replaced separately, which improves convenience and reduces the frequency of replacement of the buffer colloid as a whole. When the shafts are connected, they are generally positioned by a pin. The pin is generally installed on the pin slot 106, and the sliding block 304 of the limit baffle 301 is located at the end of the pin, which can play an axial limiting role on the pin to prevent the pin from having a large axial displacement. The sliding block 304 is limited by the limit block 305. The locking cam 306 is then tightened to the stopper 308 so that the locking cam 306 can be easily removed.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
