Description

Technical Field

[0001] This utility model relates to the field of five-axis turntable technology, and more specifically, to a waterproof and anti-tangling cable exit structure for a five-axis turntable. Background Technology

[0002] As the manufacturing industry develops towards high speed, high precision, and multi-functionality, the dynamic sealing and cable management of the five-axis rotary table, as a core component of CNC machine tools, has long been a technical challenge.

[0003] Existing technologies, such as patent CN223098575U, propose a waterproof structure for the end cover housing of a five-axis turntable. It prevents oil and water from seeping into the interior by setting a first annular protrusion and a second annular protrusion at the opening of the turntable hole. However, relying solely on the physical barrier of the protrusion cannot meet the dynamic sealing requirements under the rotating conditions of the turntable, and it does not address the problem of the internal cables of the turntable becoming entangled during rotation.

[0004] Therefore, there is an urgent need for a five-axis turntable anti-winding cable exit structure with through holes and cable chains, and dynamic sealing is achieved through a rotary sealing structure and an elastic cable exit structure. Utility Model Content

[0005] The purpose of this utility model is to propose a waterproof and anti-tangling cable outlet structure for a five-axis turntable, including a stationary turntable housing 2 sleeved outside the turntable shaft 1, and a cable outlet structure 3 provided at the cable outlet end of the housing 2, so as to solve the problems of easy tangling and poor sealing of existing turntable cables.

[0006] A waterproof and anti-tangle cable exit structure for a five-axis turntable, characterized in that it includes:

[0007] A stationary turntable housing 2 that is fitted onto the outside of the rotating shaft 1;

[0008] The cable outlet structure 3 located at the cable outlet end of the turntable housing 2 has multiple through holes 301 with diameters adapted to different cables, and adjacent through holes 301 on the same straight line are connected by slots 302.

[0009] The clamping structure 7 is connected to the cable outlet structure 3 and is also connected to the rotating shaft 1. The clamping structure 7 includes a first chuck 4 and a second chuck 5, both of which are hollow annular structures.

[0010] A first cable chain mounting bracket 6 fixed to the second chuck 5, and a second cable chain mounting bracket 9 provided on the turntable housing 2;

[0011] The cable chain 8 connects the first cable chain mounting bracket 6 and the second cable chain mounting bracket 9.

[0012] Furthermore, the cable outlet structure 3 is a disc boss structure, with the two disc surfaces at its two ends respectively engaging the first chuck 4 and the second chuck 5. The boss penetrates the hollow structure of the second chuck 5, and the three are fixed to the rotating shaft 1 by a locking member.

[0013] Furthermore, the first cable chain mounting bracket 6 has a semi-circular arc structure, with a hollow area 601 in the middle to avoid the cable exit structure 3, and bent reinforcing parts 602 at both ends.

[0014] Furthermore, one end of the cable chain 8 is connected to the first cable chain mounting bracket 6, and the other end is connected to the second cable chain mounting bracket 9. The cable chain 8 rotates around the arc-shaped structure of the first cable chain mounting bracket 6.

[0015] Furthermore, the second cable chain mounting bracket 9 integrates a mating interface 901 and a quick-connect interface 902 for external pipeline connection.

[0016] Furthermore, a rotary sealing structure 10 is provided between the rotating shaft 1 and the cable outlet end of the turntable housing 2. The rotary sealing structure 10 is a skeleton sealing ring, which is provided on the mating surface of the rotating shaft 1 and the cable outlet end of the turntable housing 2.

[0017] Furthermore, the cable outlet structure 3 is made of an elastic material, and its through hole 301 is interference-fitted with the cable to form a radial seal.

[0018] Furthermore, the first chuck 4 is disposed adjacent to the rotating shaft 1, and the outer end face of the second chuck 5 extends to form the mounting base surface of the first cable chain mounting bracket 6.

[0019] Furthermore, the radius of the arc-shaped motion trajectory of the cable chain 8 matches the radius of curvature of the first cable chain mounting bracket 6, thus limiting the cable twisting angle.

[0020] Furthermore, the slot 302 of the through hole 301 penetrates the cable outlet structure 3, so that the inner wall of the through hole 301 is fully covered after the cable is inserted.

[0021] The beneficial effects of this utility model are as follows: A five-axis turntable waterproof and anti-tangling cable exit structure includes a stationary turntable housing 2 sleeved outside the turntable shaft 1, and a cable exit structure 3 located at the cable exit end of the housing 2; it blocks leakage from the turntable mating surface through a skeleton sealing ring, and the through hole 301 in the cable exit structure 3 is interference-fitted with the cable to suppress cable gap penetration and improve waterproof capability; the clamping structure 7 includes a first chuck 4 and a second chuck 5 coaxially arranged, both of which are hollow annular structures. The second chuck 5 is fixed to a first drag chain mounting bracket 6, and the turntable housing 2 is provided with a second drag chain mounting bracket 9. The two are connected by a drag chain 8 to guide the cable to move with the turntable shaft and prevent tangling; the design of the multi-diameter through hole 301 and the slot 302 is compatible with multiple specifications of cables and is suitable for various mixed wiring scenarios; furthermore, through the modular cable exit structure 3 design, chuck clamping and sealing, and drag chain 8 guidance, tangling is effectively prevented and waterproof performance is improved.

[0035] A waterproof and anti-tangling cable exit structure for a five-axis turntable, characterized in that it comprises: a stationary turntable housing 2 sleeved outside a rotating shaft 1; a cable exit structure 3 located at the cable exit end of the turntable housing 2, which has multiple through holes 301 with diameters adapted to different cables, and adjacent through holes 301 on the same straight line are connected by slots 302; a clamping structure 7 connected to the cable exit structure 3 and connected to the rotating shaft 1, the clamping structure 7 including a first chuck 4 and a second chuck 5, both of which are hollow annular structures; a first cable chain mounting bracket 6 fixed to the second chuck 5, and a second cable chain mounting bracket 9 located on the turntable housing 2; and a cable chain 8 connecting the first cable chain mounting bracket 6 and the second cable chain mounting bracket 9.

[0036] The cable exit structure 3 is a disc-shaped boss structure, with its two end discs respectively engaging with the first chuck 4 and the second chuck 5. The boss penetrates the hollow structure of the second chuck 5, and the three are fixed to the rotating shaft 1 by locking components. The cable exit structure 3 is placed between the two chucks, making the structure compact and facilitating sealing. The first chuck 4 is located adjacent to the rotating shaft 1, and the outer end face of the second chuck 5 extends to form the mounting base surface of the first cable chain mounting bracket 6. The cable exit structure 3 is made of elastic material, and its through hole 301 is interference-fitted with the cable to form a radial seal. Radial pressure causes the elastic material to adhere tightly to the cable sheath, effectively preventing leakage from entering the turntable housing from the outside along the surface of a single cable. The groove 302 of the through hole 301 penetrates the cable exit structure 3, so that the inner wall of the through hole 301 is fully covered after the cable is inserted; eliminating possible leakage paths at the groove and achieving true full-circumference sealing.

[0037] The first cable chain mounting bracket 6 has a semi-circular arc structure, with a hollow area 601 in the middle to avoid the cable exit structure 3, and bent reinforcing parts 602 at both ends; this avoids the protruding cable exit structure at the rear, making the overall layout more compact and avoiding interference. One end of the cable chain 8 is connected to the first cable chain mounting bracket 6, and the other end is connected to the second cable chain mounting bracket 9. The cable chain 8 rotates around the arc structure of the first cable chain mounting bracket 6. The second cable chain mounting bracket 9 integrates a mating interface 901 and a quick-connect interface 902 for external pipeline connection. The radius of the arc movement trajectory of the cable chain 8 matches the radius of curvature of the first cable chain mounting bracket 6, limiting the cable twisting angle.

[0038] A rotary sealing structure 10 is provided between the rotating shaft 1 and the outlet end of the turntable housing 2. The rotary sealing structure 10 is a skeleton sealing ring, which is provided on the mating surface of the outlet end of the rotating shaft 1 and the turntable housing 2.

[0039] The beneficial effects of this utility model are as follows: A five-axis turntable waterproof and anti-tangling cable exit structure includes a stationary turntable housing 2 sleeved outside the turntable 1, and a cable exit structure 3 located at the cable exit end of the housing 2; it blocks leakage from the turntable mating surface through the skeleton sealing ring, and the through hole 301 in the cable exit structure 3 is interference-fitted with the cable to suppress cable gap penetration and improve waterproof capability; the clamping structure 7 includes a first chuck 4 and a second chuck 5 coaxially arranged, both of which are hollow annular structures. The second chuck 5 is fixed to the first drag chain mounting bracket 6, and the turntable housing 2 is provided with a second drag chain mounting bracket 9. The two are connected by a drag chain 8 to guide the cable to move with the turntable and prevent tangling; the design of the multi-diameter through hole 301 and the slot 302 is compatible with multiple specifications of cables and is suitable for various mixed wiring scenarios; furthermore, through the modular cable exit structure 3 design, chuck clamping and sealing, and drag chain 8 guidance, tangling is effectively prevented and waterproof performance is improved.
