Description

TECHNICAL FIELD

[0001] The application relates to the field of feeding and discharging equipment, in particular to a damping mechanism for a workpiece feeding and discharging rotary machine. BACKGROUND

[0002] Automatic feeding and discharging equipment is usually a component of an automatic machine tool. After the automatic feeding and discharging equipment is arranged on a semi-automatic machine tool, the machining process can be continuously and automatically performed, and the machine tool is called an automatic machine tool. A rotary machine is usually arranged in the feeding and discharging equipment. In order to avoid the position of a workbench of the rotary machine from being deviated on a base due to rotational inertia, a clamping assembly and a clamping rotating frame are arranged to prevent the position of the rotating frame on the base from being deviated due to inertia generated by the rotating frame during rotation of the rotating frame on the base. A damping mechanism needs to be used in the clamping assembly.

[0003] As disclosed in the patent with the authorized announcement number CN117921427A, a rotary machine for workpiece feeding and discharging is provided. However, the following problems still exist in actual use.

[0004] When the limiting block abuts against one end of the top rod, the first supporting spring is compressed. When the limiting block abuts against the supporting block, the second supporting spring is compressed. By arranging the first supporting spring and the second supporting spring, the contact block can prevent the contact sensor from being damaged. However, the springs can be fatigued and worn after long-time use, and thus the damping effect is poor. UTILITARIAN CONTENT

[0005] In order to solve the problem that the springs can be fatigued and worn after long-time use, the application provides a damping mechanism for a workpiece feeding and discharging rotary machine.

[0006] The damping mechanism for the workpiece feeding and discharging rotary machine provided by the application adopts the following technical scheme:

[0007] The damping mechanism for the workpiece feeding and discharging rotary machine comprises a clamping assembly. The clamping assembly comprises a sliding block slidingly arranged on the top of a base. A mounting frame is fixedly arranged on one side of the base. A contact sensor is fixedly arranged on the top of the mounting frame. A cavity one is formed in the end of the sliding block away from the contact sensor. A damping assembly is arranged in the cavity one. The damping assembly comprises a damping cylinder rotatably arranged in the cavity one. A plurality of magnets one and magnets two with the same magnetic pole arranged oppositely are arranged in the damping cylinder.

[0008] By adopting the technical scheme, the workpiece feeding and discharging rotary machine frame generates rotational inertia during rotation, and the rotational inertia of the frame increases with the increase of the workpieces on the frame. In order to reduce the rotational inertia during rotation of the frame, the damping assembly is arranged. When the limiting block abuts against one side of the damping cylinder and the damping cylinder is subjected to external force, the damping cylinder can be deformed to a certain extent, thereby absorbing and dispersing the impact force, achieving the damping effect, and preventing the contact block from damaging the contact sensor.

[0009] Preferably, a through hole is formed in the center of the damping cylinder, and a sleeve is fixedly arranged on the inner wall of the through hole.

[0010] By adopting the technical scheme, the sleeve is arranged to enhance the structural stability of the damping cylinder and increase the flexibility of rotation of the damping cylinder.

[0011] Preferably, a mounting rod is rotatably connected to the center of the sleeve, and the top and bottom of the mounting rod are fixedly connected to the top and bottom of the inner cavity of the first cavity, respectively.

[0012] By adopting the technical scheme, the damping cylinder is rotatably mounted on the mounting column through the sleeve, which can realize free rotation of the damping cylinder within a certain range, so that the damping cylinder can more flexibly cope with the impact force when being impacted, and the impact force is converted into rotational kinetic energy, thereby reducing the impact force. The design of the rotary mounting allows the damping cylinder to adapt to impacts of different angles and directions, improving its flexibility and adaptability in actual application.

[0013] Preferably, the damping cylinder is made of EVA material.

[0014] By adopting the technical scheme, the damping cylinder is made of EVA material, which has strong elasticity, wear resistance, chemical resistance, ultraviolet aging resistance, color fading resistance and damage resistance, and a long service life, thereby improving the service life of the device.

[0015] Preferably, a second cavity is formed in the damping cylinder.

[0016] By adopting the technical scheme, the design of the second cavity allows the EVA material to have more space for deformation when subjected to impact force, which can better absorb and disperse the impact force. The second cavity can also reduce the overall weight of the damping cylinder. The design of the second cavity can also improve the impact resistance of the damping cylinder, allowing it to maintain its shape more stably when being impacted, and not easily damaged or deformed.

[0017] Preferably, the plurality of magnets one and the plurality of magnets two are respectively fixedly connected to the inner wall B and the inner wall A of the second inner cavity.

[0018] By adopting the above technical scheme, the magnet one and the magnet two arranged opposite to each other generate repulsion force, and when the shock-absorbing cylinder is subjected to impact force, the repulsion force helps to absorb and disperse the impact force, thereby achieving the shock-absorbing effect

[0019] Preferably, the plurality of magnet ones are arranged in a ring array.

[0020] By adopting the above technical scheme, the repulsion force between the magnet one and the magnet two can be better distributed on the ring structure, and when the shock-absorbing cylinder is subjected to impact force, the repulsion force helps to absorb and disperse the impact force, thereby achieving better shock-absorbing effect.

[0021] Preferably, the inner wall of the sleeve abuts against the surface of the mounting rod.

[0022] By adopting the above technical scheme, the friction between the two is reduced, thereby reducing the wear and prolonging the service life.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. By arranging the shock-absorbing assembly, when the limiting block abuts against one side of the shock-absorbing cylinder, the shock-absorbing cylinder can deform when subjected to external force, thereby absorbing and dispersing the impact force and achieving the shock-absorbing effect. Meanwhile, the shock-absorbing cylinder is provided with a plurality of magnet ones and magnet twos arranged opposite to each other, so that repulsion force is generated, thereby achieving the shock-absorbing purpose. The rotational inertia of the rotating frame is weakened, and the contact block is prevented from damaging the contact sensor.

[0025] 2. The shock-absorbing cylinder is made of EVA material, which has strong elasticity, wear resistance, chemical resistance, ultraviolet aging resistance, and is not easy to fade and damage, and has long service life, thereby improving the service life of the device.

[0034] The following will be described in detail in combination with the accompanying drawings Figures 1-5 The application is further described in detail.

[0035] The embodiment of the application discloses a damping mechanism for a workpiece feeding and discharging rotary machine.

[0036] Referring to Figures 1-3 A damping mechanism for a workpiece feeding and discharging rotary machine, comprising a clamping assembly 1 (which is the assembly in the patent with the patent authorization announcement No. CN117921427A, and the structure and principle thereof will not be described here), the clamping assembly 1 comprises a sliding block 2 slidingly arranged on the top of a base 4, one end of the top of the base 4 is fixedly provided with a baffle 10, the baffle 10 is arranged in parallel and spaced apart from the sliding block 2, the side of the baffle 10 close to the sliding block 2 is fixedly connected with a slide rail 8, the side surface of the sliding block 2 is provided with a sliding groove 9 matched with the shape of the slide rail 8, one end of the slide rail 8 away from the baffle 10 penetrates through the sliding groove 9, and the bottom of the sliding block 2 abuts against the top of the base 4, a mounting bracket 3 is fixedly installed on the side of the base 4 away from the slide rail 8, and the side of the mounting bracket 3 adhering to the base 4 is fixedly connected with the side surfaces of the sliding block 2 and the baffle 10, and a contact sensor 5 is fixedly installed on the top of the mounting bracket 3 close to the sliding block 2.

[0037] A cavity one 6 is arranged on the surface of the sliding block 2 away from the contact sensor 5, and a damping assembly 7 is arranged in the cavity one 6, the damping assembly 7 comprises a damping cylinder 73 rotatably installed in the cavity one 6, a mounting rod 71 is fixedly installed on the top and the bottom of the inner cavity of the cavity one 6, a sleeve 72 is movably sleeved on the surface of the mounting rod 71, and the inner hole diameter of the sleeve 72 is equal to the diameter of the mounting rod 71, limit discs 78 are fixedly connected to the top and the bottom of the surface of the mounting rod 71, and the top and the bottom of the sleeve 72 abut against the inner sides of the limit discs 78 located on the top and the bottom respectively, the diameter of the limit disc 78 is greater than the diameter of the mounting rod 71, so as to avoid the sleeve 72 from sliding on the surface of the mounting rod 71, a through hole 74 is arranged on the top center of the damping cylinder 73 made of EVA material, the sleeve 72 is located in the through hole 74, and the top and the bottom of the sleeve 72 are flush with the top and the bottom of the damping cylinder 73, and the surface of the sleeve 72 is fixedly connected with the inner wall of the through hole 74.

[0038] The rotating frame of the workpiece loading and unloading rotary machine generates rotational inertia during rotation. As the number of workpieces on the rotating frame increases, the rotational inertia of the rotating frame also increases. In order to reduce the rotational inertia during the rotation of the rotating frame, a shock-absorbing component 7 is set. When the limiting block 11 (which is the structure fixed on the rotating frame in the patent with patent authorization announcement number CN117921427A, and will not be described in detail here) abuts against one side of the shock-absorbing cylinder 73, the shock-absorbing cylinder 73 can undergo a certain deformation when subjected to external force, thereby absorbing and dispersing the impact force, achieving the effect of shock absorption, and preventing the contact block 12 (the contact block 12 is fixed to the top of the limiting block 11 near the contact sensor 5) from damaging the contact sensor 5.

[0039] Reference Figure 4 , Figure 5 The shock absorber 73 has an annular cavity 75 in the middle of its interior. The cavity 75 has two annular inner walls, one annular inner wall A752 and the other annular inner wall B751. Several magnets 76 are fixed to the inner wall B751 and several magnets 77 are fixed to the inner wall A752. The magnets 76 and magnets 77 are arranged in a one-to-one correspondence, and the magnetic poles of the magnets 76 and magnets 77 are the same.

[0040] When the limiting block 11 comes into contact with one side of the shock absorber 73, the shock absorber 73 is equipped with several magnets 76 and 77 with the same poles facing each other, so a repulsive force is generated, thereby achieving the purpose of shock absorption and preventing the contact block 12 from damaging the contact sensor 5.

[0041] The implementation principle of a shock-absorbing mechanism for a workpiece loading and unloading rotary machine according to an embodiment of this application is as follows: During the rotation of the rotating frame of the workpiece loading and unloading rotary machine, rotational inertia is generated. As the number of workpieces on the rotating frame increases, the rotational inertia of the rotating frame also increases. In order to reduce the rotational inertia during the rotation of the rotating frame, a shock-absorbing component 7 is provided. When the limiting block 11 abuts against one side of the shock-absorbing cylinder 73, the shock-absorbing cylinder 73 can undergo a certain deformation when subjected to external force, thereby absorbing and dispersing the impact force, achieving the shock-absorbing effect, and preventing the contact block 12 from damaging the contact sensor 5. At the same time, the shock-absorbing cylinder 73 is provided with several magnets 76 and 77 arranged with the same pole opposite each other, so a repulsive force is generated, thereby achieving the purpose of shock absorption and preventing the contact block 12 from damaging the contact sensor 5.

[0042] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
