In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention.
The one-to-many harness clamping method provided by the embodiment of the invention is used for clamping and fixing the main harness and the branch harness by using the one-to-many harness clamping device, and the one-to-many harness clamping device is explained in detail below.

The motor 210 is preferably a stepping motor, and the rotation angle of the output shaft of the motor can be precisely controlled.
The rotating shaft 230 is connected with an output shaft of the motor 210 through a coupler, and the rotating shaft 230 rotates synchronously with the output shaft of the motor 210.
The number of the active clamping mechanisms 240 is at least two, and the active clamping mechanisms are used for clamping and fixing the main wiring harness. The active clamping mechanism 240 is located below the main harness and clamps and fixes the main harness from bottom to top.
The number of the active clamping mechanisms 240 under the main harness is at least one set to clamp and fix the main harness. Preferably, a set of active clamping mechanisms 240 is respectively arranged at both ends of the main harness, and the number of the active clamping mechanisms 240 arranged at the middle position of the main harness is selected according to the length of the main harness.
As shown in fig. 2 and 3, the present embodiment exemplarily shows four sets of active clamping mechanisms 240, three sets of which are disposed below the main harness, that is, two sets of active clamping mechanisms are disposed at two ends and a middle position of the main harness, and the other set of active clamping mechanisms is disposed below the branch harness.
The number of the cams 220 is the same as that of the active clamping mechanisms 240, each cam 220 is respectively sleeved on the rotating shaft 230 at a position corresponding to each active clamping mechanism 240, the bottom end of each active clamping mechanism 240 is respectively abutted against the corresponding cam 220, each cam 220 is driven to rotate when the rotating shaft 230 rotates, and each cam 220 drives each active clamping mechanism 240 to open and close so as to clamp and fix the wire harness.
In order to avoid the synchronous opening and closing of the active clamping mechanisms 240, the cams 220 are sleeved on the rotating shaft 230 after rotating around the rotating shaft 230 by different angles with the rotating shaft 230 as a rotating center. The stroke of each active clamping mechanism 240 is changed in this way, so that the opening and closing time of each active clamping mechanism 240 is asynchronous, the purpose of sequentially controlling each active clamping mechanism 240 is achieved, and the problem that the wire harness is damaged due to overlarge axial force caused by the fact that the active clamping mechanisms 240 are integrally opened and closed is solved.
The rotation angle of each cam 220 is determined according to the opening and closing sequence of each active clamping mechanism 240, so as to control each active clamping mechanism 240 to open and close according to a predetermined sequence.
The specific structure of the active clamping mechanism 240 is shown in fig. 4, the active clamping mechanism 240 includes a spring 241, a sliding sleeve 242, a sliding rod 243 and a clamping jaw 244; the bottom end of the sliding rod 243 is provided with a circle of boss 2431, the boss 2431 is abutted to the cam 220, the sliding rod 243 is driven to move up and down by the rotation of the cam 220, the top end of the sliding rod 243 is connected with the clamping jaw 244, and the clamping jaw 244 is driven to open and close when the sliding rod 243 moves up and down to clamp and fix the wire harness.
The spring 241 and the sliding sleeve 242 are respectively sleeved on the sliding rod 243, the spring 241 is located below the sliding sleeve 242, one end of the spring 241 is abutted to the boss 2431, the other end of the spring 241 is abutted to the bottom of the sliding sleeve 242, and the spring 241 is used for ensuring that the cam 220 is always in contact with the boss 2431 and playing a role in assisting lifting of the sliding rod 243.
The top of the sliding sleeve 242 has an opening, the width of the opening is slightly larger than that of the clamping jaw 244, and the opening has two functions, namely, when the clamping jaw 244 ascends, the clamping jaw 244 can extend out of the sliding sleeve 242; second, it acts to close the jaw 244 when the jaw 244 is lowered.
Because the cams 220 are sleeved on the rotating shaft 230 at different rotation angles, the movement strokes of the sliding rods 243 are different, and the opening and closing time of the clamping jaws 244 is different, so that the purpose of sequentially opening and closing and clamping the fixed wire harness by the active clamping mechanisms 240 is realized.
The clamping jaw 244 may be an integral structure or a separate structure, when the clamping jaw 244 is an integral structure, the clamping jaw 244 is made of an elastic material and bent into two fingers, the two fingers are in an open state when not being subjected to an external force, when the two fingers extend out of the opening of the sliding sleeve 242, the two fingers are naturally opened under the action of an elastic force, and when the two fingers are retracted into the sliding sleeve 242, the two fingers are closed under the closing of the opening.
When the clamping jaw 244 is a split structure, the clamping jaw 244 is opened and closed by hinging two fingers, when the two fingers extend out of the opening of the sliding sleeve 242, the clamping jaw is naturally opened under the action of gravity, and when the two fingers retract into the sliding sleeve 242, the clamping jaw is closed by closing the opening.
The structure of the driven clamping mechanism 250 is the same as that of the driving clamping mechanism 240, and thus, the description thereof is omitted. The number of the driven clamping mechanisms 250 is at least one set, the specific number is determined according to the number of the branch bundles, and the plurality of sets of driven clamping mechanisms 250 are respectively positioned above the corresponding branch bundles. The plurality of sets of driven clamping mechanisms 250 can be linked with the same set of driving clamping mechanism 240, and can also be linked with different driving clamping mechanisms 240, and which set of driving clamping mechanism 240 to link is determined according to the arrangement positions of the driven clamping mechanisms 250.
If a plurality of sets of driven clamping mechanisms 250 are linked with the same set of driving clamping mechanism 240, a sliding sleeve 242 of the set of driving clamping mechanism 240 and a sliding sleeve of each set of driven clamping mechanism 250 are provided with a sliding hole 2421; if multiple sets of driven clamping mechanisms 250 are coupled with different driving clamping mechanisms 240, sliding holes 2421 need to be formed on the sliding sleeves of the multiple sets of driven clamping mechanisms 250 and the sliding sleeves 242 of the multiple sets of driving clamping mechanisms 240, that is, the driving clamping mechanism 240 which does not need to be coupled does not need to be provided with the sliding sleeves 2421.
The driven clamping mechanism 250 is linked with the driving clamping mechanism 240 through a connecting rod 260.
In one embodiment, two driven gripper mechanisms 250, as shown in fig. 2 and 3, are illustrated.
The two sets of driven clamping mechanisms 250 are positioned at two sides of the same driving clamping mechanism 240, the two sets of driven clamping mechanisms 250 are linked with the driving clamping mechanism 240 through a connecting rod 260, the connecting rod 260 has three end parts, the three end parts respectively penetrate through the sliding holes 2421 and then are connected with the sliding rods 243 in the linked driving clamping mechanism 240 and the sliding rods in the two sets of driven clamping mechanisms 250, when the sliding rods 243 in the driving clamping mechanism 240 lift up and down, the connecting rod 260 drives the sliding rods in the driven clamping mechanisms 250 to lift up and down synchronously, namely, the clamping jaws 244 in the linked driving clamping mechanism 240 and the clamping jaws in the two sets of driven clamping mechanisms 250 open and close synchronously to clamp the wiring harnesses.
The sliding sleeve 242 in the driving clamping mechanism 240 and the sliding sleeve in the driven clamping mechanism 250 are respectively fixed in the fixing hole of the base plate 270, the part below the sliding hole 2421 of the sliding sleeve in the driving clamping mechanism 240 and the part below the sliding hole of the sliding sleeve in the driven clamping mechanism 250 are respectively located below the base plate 270, and the part above the sliding hole 2421 of the sliding sleeve in the driving clamping mechanism 240 and the part above the sliding hole of the sliding sleeve in each set of the driven clamping mechanism are respectively located above the base plate 270.
A switch 280 is further fixed on the substrate 270, the switch 280 is used for controlling the rotation angle of the motor 210, and the motor 210 operates for a preset number of degrees when the switch 280 is touched once, so that the rotation of the rotating shaft 230 for one circle is ensured, and all the clamping jaws complete one opening and closing.
The above details describe the structure of the one-to-many wire harness clamping device provided by the present invention, and the present invention can also realize clamping and fixing of one-to-one wire harness and many-to-many wire harness by increasing or decreasing the number of the driving clamping mechanism and the driven clamping mechanism.
As shown in fig. 5, the method for clamping a wire harness by using a one-to-many wire harness clamping device comprises the following steps:
step 1, moving a main wire harness and a plurality of branch wire harnesses to the upper parts of a corresponding driving clamping mechanism and a corresponding driven clamping mechanism.
The number of the branch bundles and the number of the driven clamping mechanisms are determined according to actual requirements.
And the main wire harness and the branch wire harness are moved to the upper parts of the driving clamping mechanism and the driven clamping mechanism through a manipulator or a portal frame.
And 2, driving the rotating shaft to rotate through the motor so as to drive the cam sleeved on the rotating shaft to rotate.
As shown in fig. 6a and 6b, the number of the cams 220 is at least two, and the cams are sleeved on the rotating shaft 230 at different rotation angles, and when the rotating shaft 230 is driven by the motor 210 to rotate, the strokes of the cams 22 are different.
And 3, driving the driving clamping mechanism to open and close to clamp the main wire harness through the rotation of the cam.
As shown in fig. 6a and 6b, the number of the active clamping mechanisms 240 is the same as that of the cams 220, and the active clamping mechanisms 240 are respectively located above the cams 220, and the bottoms of the sliding rods 243 of the active clamping mechanisms 240 abut against the cams 220.
The step 3 specifically comprises the following steps:
and 301, driving a sliding rod in the active clamping mechanism abutted against the cam to move upwards by the cam.
The sliding rod 243 is driven by the rotation of the cam 220 to lift upwards, and the sliding sleeve 242 is fixed, so the spring 241 is deformed to store energy.
Step 302, the slide bar drives the clamping jaw connected to the top end of the slide bar to move upwards.
A jaw 244 is secured to the top end of the rod 243 and moves the jaw 244 upward as the rod 243 is raised upward.
And 303, opening the fingers when the clamping jaws extend out of the sliding sleeves sleeved on the sliding rods.
When the jaws 244 extend out of the opening of the sliding sleeve 242, the fingers for gripping the wiring harness are opened by gravity or resiliency.
And step 304, driving the slide bar to return to the original position by the cam after the slide bar reaches the maximum stroke.
After the sliding rod 243 ascends to the maximum stroke, the cam 220 starts to drive the sliding rod 243 to move downwards, and at the moment, the spring 241 releases energy to enable the sliding rod 243 to return.
And 305, driving the clamping jaw to move downwards by the sliding rod, and closing the finger under the action of the sliding sleeve.
The slide bar 243 drives the clamping jaw 244 to move downwards, so that the clamping jaw 244 is retracted into the sliding sleeve 242, and fingers of the clamping jaw 244 are closed under the action of an opening of the sliding sleeve 242.
Since the cams 220 are rotated by different angles and then fitted to the rotating shaft 230, the strokes of the cams 22 are different from each other, and the strokes of the active gripping mechanisms 240 abutting against the cams 220 are different from each other, so that the opening and closing times of the jaws 244 in the active gripping mechanisms 240 are not synchronized with each other.
For example: when the jaw on the left in fig. 6a and 6b is open, the middle jaw is closed, and when the jaw on the left is closed, the middle jaw is open.
Therefore, the purpose of sequentially controlling the opening and closing of the clamping jaws 244 is achieved, and the problem that the wire harness is damaged due to overlarge axial force caused by the integral opening and closing of the clamping jaws 244 is solved.
And 4, driving the driving clamping mechanism to drive the driven clamping mechanism linked with the driving clamping mechanism to open and close to clamp the branch bundles.
The driving clamping mechanism 240 farthest from the motor 210 is connected to the plurality of driven clamping mechanisms 250 through a connecting rod 260, each end of the connecting rod 260 is fixedly connected to a sliding rod 243 of the driving clamping mechanism 240 and a sliding rod of the driven clamping mechanism 250, and when the driving clamping mechanism 240 operates, the plurality of driven clamping mechanisms 250 and the driving clamping mechanism 240 operate synchronously to clamp the plurality of branch cables.
The motor 210 in the invention selects a stepping motor as a driving motor, the control is carried out through the switch 280, the stepping motor rotates 60 degrees every time the switch 280 is touched, the cam 220 and the stepping motor rotate synchronously, when the cam 220 rotates 20 degrees, the sliding rod 243 is driven to reach the maximum stroke, the spring 241 ensures that the cam 220 is always contacted with the sliding rod 243, when the cam 220 rotates 20 degrees again, the sliding rod 243 starts to move towards the return direction, when the cam 220 rotates 60 degrees, the sliding rod 243 returns to the original position, the clamping jaw 244 is closed, and one clamping action is completed.
