Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, and in particular to an anti-detachment fixing fixture for industrial wire harness processing and its application method. Background Technology

[0002] In the processing, inspection and handling of large or complex wire harnesses, it is usually necessary to use anti-detachment fixing fixtures to protect the wire harnesses from detachment, and to stably fix the wire harness body, connectors and branch points in the predetermined positions to prevent them from moving during processing and inspection. This is not only a guarantee for efficient production, but also a core tool to prevent assembly errors, protect connectors and ensure the accuracy of testing.

[0003] When using common wire harness anti-detachment fixing fixtures, because the wire harness is long and narrow, it is usually necessary to fix the wire harness terminals and the wire harness body separately. This is done by placing the wire harness on the fixture, adjusting the terminal clamps to hold and fix the wire harness terminals, and then using clamps to fix the wire harness connection terminals to prevent the connection between the wire harness body and the terminals from loosening. At the same time, the fixture is used to fix the wire harness body, making the use of wire harness anti-detachment fixing fixtures cumbersome and inconvenient for fixing wire harnesses.

[0041] A method for using an anti-detachment fixing fixture in industrial wire harness processing includes the following steps:

[0042] Step 1: Place the wire harness on the upper surface of the fixed block so that the wire harness terminals are located between the two mounting blocks, one end of the wire harness is positioned between the two clamping blocks, and the other end of the wire harness is positioned below the multiple movable blocks.

[0043] Step 2: By rotating the screw, the two clamping blocks move horizontally towards the center, using the two clamping blocks to press and fix one end of the wire harness. The mounting block and positioning block move horizontally together with the clamping blocks. The two positioning blocks fit against both sides of the wire harness terminal. As the clamping blocks continue to move, the positioning blocks press against the wire harness terminal, compressing and deforming the compression spring. Using the elasticity of the compression spring, the positioning blocks are pushed to press and fix the wire harness terminal.

[0044] Step 3: The clamping block drives the extrusion rod to move horizontally. The extrusion rod moves in the mounting groove on the movable block and presses against the inner wall of the mounting groove, pushing multiple movable blocks to rotate downwards. The multiple movable blocks are used to press and fix the other end of the wire harness downwards.

[0045] The technical effects and advantages of this invention are as follows:

[0046] (1) The present invention places the wire harness on the upper surface of the fixing block, with one end of the wire harness located between the two clamping blocks, and then rotates the screw so that the two clamping blocks move in opposite directions along the two ends of the screw to adjust the position of the clamping blocks. The two clamping blocks move towards one end of the wire harness, which facilitates the squeezing and fixing of one end of the wire harness.

[0047] (2) The present invention moves the clamping block together with the mounting block and the positioning block, so that the positioning block fits against the outer wall of the wire harness terminal and positions the wire harness terminal. As the clamping block moves continuously, the positioning block is pressed against the wire harness terminal, pushing the positioning block and the movable rod to one side, compressing and deforming the compression spring, and using the elastic effect of the compression spring to push the limiting block and the movable rod outward, so that the positioning block presses against one side of the terminal, which facilitates the fixing of the wire harness terminal.

[0048] (3) When the two clamping blocks move toward one end of the wire harness, they drive the extrusion rod to move together, so that the extrusion rod slides in the mounting groove and presses against the mounting groove, pushing the movable block to rotate downward, so that multiple movable blocks press down and fix the other end of the wire harness, which is convenient for fixing the wire harness.

The movable rod 44 is used to connect the mounting block 42 and the positioning block 43. The movable rod 44 moves together with the positioning block 43. The fixing tube 45 is fixedly connected to the outer wall of the mounting block 42. The fixing tube 45 is slidably inserted into one end of the movable rod 44. The fixing tube 45 is used to install and accommodate the movable rod 44. When the positioning block 43 presses against the outer wall of the wire harness terminal... When pressed together, the positioning block 43 and the movable rod 44 are pushed to one side, and the movable rod 44 slides into the fixed tube 45. The limiting block 46 is fixedly connected to one end of the movable rod 44. The limiting block 46 is slidably inserted into the inner cavity of the fixed tube 45. The limiting block 46 moves with the movable rod 44 in the fixed tube 45 to prevent the movable rod 44 from separating from the fixed tube 45, and to compress and deform the compression spring 47. The compression spring 47 is set in the fixed tube 45, and one end of the compression spring 47 is in contact with the outer wall of the limiting block 46. When the positioning block 43 drives the movable rod 44 and the limiting block 46 to slide into the inner cavity of the fixed tube 45, the limiting block 46... Six compression springs 47 are compressed and deformed, and the elasticity of the compression springs 47 is used to push the limiting block 46 and the movable rod 44 outward, so that the positioning block 43 is pressed against the terminal side; the sliding groove 48 is opened on the top of the fixed tube 45, and the sliding groove 48 is elongated and used to install and accommodate the sliding block 49; the sliding block 49 is fixedly connected to the top of the limiting block 46, and the sliding block 49 and the sliding groove 48 are slidably interlocked. The sliding block 49 moves together with the limiting block 46 and slides in the sliding groove 48, limiting the movement of the limiting block 46 and the positioning block 43 and preventing the positioning block 43 from rotating.

[0062] The pressing structure 5 includes a fixed base 51, a groove 52, a movable block 53, a fixed shaft 54, a mounting groove 55, a pressing rod 56, and a protective pad 57. The fixed base 51 is fixedly connected to both sides of the upper surface of the fixed block 2, and the fixed bases 51 are staggered. The fixed base 51 is used to install the movable block 53. The groove 52 is provided on the fixed base 51 and is used to install the fixed shaft 54. The bottom of the movable block 53 is provided in the groove 52, and the movable block 53 is obliquely arranged. Multiple movable blocks 53 are staggered on both sides of the upper surface of the fixed block 2 to press the other end of the wire harness downward. The fixed shaft 54 ​​is fixedly connected to the bottom of the movable block 53. The fixed shaft 54 ​​is rotatably inserted into the inner wall of the groove 52. The bottom of the movable block 53 is rotatably connected to the fixed base 51 through the fixed shaft 54, so that the movable block 53 rotates around the fixed shaft 54. The mounting groove 55 is opened on the movable block 53 and is elongated. The mounting groove 55 is used to install and accommodate the pressing rod. Rod 56; One end of the pressing rod 56 is fixedly connected to the front of the clamping block 31. The pressing rod 56 is slidably inserted into the mounting groove 55. The outer wall of the pressing rod 56 is in contact with the inner wall of the mounting groove 55. The pressing rod 56 moves horizontally together with the clamping block 31. When the two clamping blocks 31 move towards one end of the wire harness, they drive the pressing rod 56 to move together, so that the pressing rod 56 slides in the mounting groove 55 and presses against the inside of the mounting groove 55, pushing the movable block 53 to rotate downward, so that multiple movable blocks 53 press and fix the other end of the wire harness downward. The protective pad 57 is fixedly connected to the lower surface of the movable block 53. The protective pad 57 is made of rubber material. The movable block 53 contacts the wire harness through the protective pad 57. The elasticity of the protective pad 57 prevents the movable block 53 from damaging the wire harness. As the movable block 53 presses the wire harness, the wire harness will deform and unfold to a certain extent, ensuring that the clamping block 31 and the movable block 53 fix the two ends of the wire harness synchronously.

[0063] A method for using an anti-detachment fixing fixture in industrial wire harness processing includes the following steps:

[0065] Step 2: By rotating the screw 34, the two clamping blocks 31 are moved horizontally towards the center through the threaded connection. The two clamping blocks 31 press and fix one end of the wire harness. The mounting block 42 and the positioning block 43 move horizontally together with the clamping blocks 31. The two positioning blocks 43 are in contact with both sides of the wire harness terminal. As the clamping blocks 31 continue to move, the positioning blocks 43 are pressed against the wire harness terminal, compressing and deforming the compression spring 47. The elasticity of the compression spring 47 is used to push the positioning blocks 43 to press and fix the wire harness terminal.

[0066] Step 3: The clamping block 31 drives the pressing rod 56 to move horizontally. The pressing rod 56 moves in the mounting groove 55 on the movable block 53 and presses against the inner wall of the mounting groove 55, pushing multiple movable blocks 53 to rotate downwards. The multiple movable blocks 53 are used to press and fix the other end of the wire harness downwards.
