Description

Technical Field

[0001] This utility model relates to the field of turntable equipment technology, specifically to a wire harness anti-crossing structure in a test turntable. Background Technology

[0002] Currently, in the application of various turntable devices (such as rotating worktables in industrial production, stage rotating turntables, radar turntables, etc.), there are many shortcomings in the arrangement of internal electrical wiring (including power lines, signal lines, etc.) and various pipes (such as hydraulic pipes, air pipes, etc.). For example, traditional wiring and conduit routing methods often involve simply laying the wires and pipes haphazardly inside the turntable, which leads to the following problems: messy wiring, easy tangling and damage of wires, and signal interference. Utility Model Content

[0003] The purpose of this utility model is to design a wire harness anti-crossing structure for a test turntable to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: It includes a support frame with a rotating body and a test turntable fixed to the rotating body. A first wire harness connected to the test turntable passes through a rotating disk in the rotating body. Several crossbars are fixed to the rotating disk at one end away from the test turntable. The crossbars pass through a take-up reel, which is fixedly connected to the crossbars. The first wire harness exits from the rotating disk and winds around the take-up reel. The end of the first wire harness away from the take-up reel is clamped by a first wire clamp, which is fixed to the support frame. The length of the first wire harness between the first wire clamp and the take-up reel is the rotational allowance of the first wire harness.

[0004] Furthermore, the first wire bundle between the first wire clamp and the take-up reel is U-shaped, and a limiting roller is provided on the outer side of the vertical line in the U-shaped first wire bundle.

[0005] Furthermore, a limiting block is fixed to the rotating disk at one end away from the test turntable to prevent the first wire harness located on the take-up reel from shifting.

[0006] Furthermore, the limiting block has a notch, and the two end plates of the take-up reel are located within the notch.

[0007] Furthermore, a second wire clamp for clamping the first wire harness is fixed to the rotating disk at one end away from the test turntable, and the first wire harness passes through the second wire clamp, the take-up reel, and the first wire clamp in sequence.

[0008] Furthermore, the second wire harness connected to the test turntable passes through the rotating disk in the rotating body. After the second wire harness exits from the rotating disk, it is clamped by the third wire clamp fixed to the crossbar. A protective cover is fixed to the support frame. The bottom of the protective cover is provided with a through hole for the first wire harness and the second wire harness to move. After passing through the third wire clamp and hanging down, the second wire harness coils around the outer shell of the protective cover from the end away from the third wire clamp.

[0009] Furthermore, a fourth wire clamp for clamping the second wire harness is fixedly attached to the outer casing.

[0010] Furthermore, the first wire harness is a wire harness, and the second wire harness is a ribbon cable.

[0011] Furthermore, the protective cover is provided with two rotating rollers, and the second wire harness is located between the two rotating rollers.

[0012] Furthermore, a limiting block is fixed to the take-up reel, and the limiting block is provided with a through groove. The second wire bundle passing through the rotating disk passes sequentially through the through groove, the third wire clamp, between the two rotating rollers, the through hole, and the fourth wire clamp.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is equipped with a take-up reel. After the first wire harness passes through the rotating disc, it is coiled on the take-up reel. There is a rotational allowance between the first wire clamp and the take-up reel. Therefore, when the test turntable rotates, the first wire harness will be coiled on the take-up reel. This prevents problems such as messy wiring, easy tangling and damage of lines, and signal interference. Attached Figure Description

Detailed Implementation

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] Example: Please refer to Figure 1-2 A wire harness anti-crossing structure in a test turntable includes a support frame 1002 on which a rotating body 2010 is mounted and a test turntable 2002 fixed to the rotating body 2010. A first wire harness 2008 connected to the test turntable 2002 passes through a rotating disk 1004 in the rotating body 2010. Several crossbars 2003 are fixedly connected to the rotating disk 1004 at one end away from the test turntable 2002. The crossbars 2003 pass through a take-up reel 2009, and the take-up reel 2009 is fixedly connected to the crossbars 2003. A first wire harness 2008 emerges from the rotating disk 1004 and coils around the take-up reel 2009. The end of the first wire harness 2008 facing away from the take-up reel 2009 is clamped by a first wire clamp, which is fixed to the support frame 1002. The length of the first wire harness 2008 between the first wire clamp and the take-up reel 2009 is the rotational allowance of the first wire harness 2008. The rotating body 2010 is a DD motor, and the DD motor has a through hole in the middle for the first wire harness 2008 to pass through. Therefore, when the DD motor starts, the rotating disk... Rotation of 1004 causes the test turntable 2002 to rotate, which in turn causes the first wire harness 2008 to rotate, thereby causing the take-up reel 2009 to rotate. When the take-up reel 2009 rotates, the first wire harness 2008 will be coiled around it, reducing the rotational allowance. When the DD motor reverses, the take-up reel 2009 will also reverse, causing the first wire harness 2008 coiled around it to unwind sequentially, increasing the rotational allowance. Therefore, in this practical application, the test turntable 2002 rotates... At this time, the wire harness will be coiled and detached on the take-up reel 2009, thereby preventing problems such as messy wiring, easy tangling and damage of lines, and signal interference. The first wire harness 2008 between the first wire clamp and the take-up reel 2009 is U-shaped. The vertical line of the U-shaped first wire harness 2008 is provided with a limiting roller 2006, which satisfies sufficient rotational margin while preventing the first wire harness 2008 from deviating too much after detaching from the take-up reel 2009, which would be detrimental to the stable winding of the first wire harness 2008.

[0020] Furthermore, a limiting block 2007 is fixedly connected to the rotating disk 1004 at one end away from the test turntable 2002 to prevent the first wire harness 2008 located on the take-up reel 2009 from shifting. The limiting block 2007 has a notch, and the two end plates of the take-up reel 2009 are located within the notch, thereby ensuring that the first wire harness 2008 can be accurately wound onto the take-up reel 2009. A second wire clamp is fixedly connected to the rotating disk 1004 at one end away from the test turntable 2002 to clamp the first wire harness 2008. The first wire harness 2008 passes through the second wire clamp, the take-up reel 2009, and the first wire clamp in sequence, ensuring... The anti-crossing point of the first wire harness is located between the first and second wire clamps. The wire harness outside the first and second wire clamps is a fixed end, ensuring stable transmission of the first wire harness 2008. Furthermore, the second wire harness 2004, connected to the test turntable 2002, passes through the rotating disk 1004 in the rotating body 2010. After exiting the rotating disk 1004, the second wire harness 2004 is clamped by a third wire clamp fixed to the crossbar 2003. A protective cover 2001 is fixed to the support frame 1002. The bottom of the protective cover 2001 has a through hole for the first and second wire harnesses 2004 to move. After passing through the through hole and hanging down, the second wire harness coils around the outer shell of the cover 2001 from the end away from the third wire clamp. A fourth wire clamp for clamping the second wire harness 2004 is fixed to the outer shell, the principle of which is the same as the anti-crossing mechanism of the first wire harness 2008; the difference is that the first wire harness 2008 is a wire harness, while the second wire harness 2004 is a ribbon cable. Wire harnesses are mostly used for power supply, while ribbon cables are mostly used for data transmission; therefore, this utility model can achieve anti-crossing of different types of wire harnesses during rotation. The bottom of the cover 2001 is provided with two rotating rollers 2005, and the second wire harness 2004 is located between the two rotating rollers 2005, ensuring the second... The wire harness 2004 moves stably; while the take-up reel 2009 is fixedly connected to a limiting block 2007, which is provided with a through groove. The second wire harness 2004, which passes through the rotating disk 1004, passes through the through groove, the third wire clamp, between the two rotating rollers 2005, the through hole and the fourth wire clamp in sequence, ensuring that the anti-crossing point of the second wire harness is between the third and fourth wire clamps. The wire harness outside the third and fourth wire clamps is the fixed end, ensuring the stability of the signal transmission of the second wire harness 2004; in addition, all four wire clamps can be implemented by using two grooved clamping plates to clamp the wire harness, which will not be elaborated on here.

[0021] The working principle of this embodiment is as follows: When the DD motor starts, the rotating disk 1004 rotates, causing the test turntable 2002 to rotate, which in turn causes the first wire harness 2008 and the second wire harness 2004 to rotate. Simultaneously, the take-up reel 2009 and the crossbar 2003 will rotate. When the take-up reel 2009 rotates, the first wire harness 2008 will coil around it, while when the crossbar 2003 rotates, the second wire harness 2004 will coil around it. When the DD motor reverses, the take-up reel 2009 and the crossbar 2003 will also reverse. At this time, the first wire harness 2008 coiled on the take-up reel 2009 will disengage sequentially, and the second wire harness 2004 coiled on the crossbar 2003 will disengage sequentially. Therefore, when the test turntable 2002 in this application rotates, the wire harness will coil and disengage on the take-up reel 2009 and the crossbar 2003, thereby preventing problems such as messy wiring, easily tangled and damaged lines, and signal interference.
