Description

Technical Field

[0001] This utility model relates to the field of wire harness testing technology, and specifically to a thrust testing mechanism for wire harnesses. Background Technology

[0002] Wire harnesses are primarily used for electrical connections in electronic products, and are made by crimping or soldering cables and terminals together. After processing, wire harnesses require several tests, such as the connection strength between terminals and cables, to determine whether the wire harness processing is qualified. Current thrust testing mechanisms generally use cylinders or motors as the output power source. Due to power loss during transmission, the actual testing force acting on the cable will be less than the output force of the cylinder or motor, resulting in inaccurate set thrust during testing, and consequently, the wire harness strength failing to meet usage requirements. Utility Model Content

[0003] To address the technical problems in the prior art, this utility model provides a thrust detection mechanism for wire harnesses, comprising a fixed plate, a motor assembly, a lead screw module, a sliding assembly, and a top wire block. The motor assembly is fixedly mounted on the fixed plate, and its output shaft is connected to the lead screw module via a coupling. The sliding assembly is slidably connected to the fixed plate and reciprocates along the axis of the lead screw module under the drive of the lead screw module and the motor assembly. The top wire block is connected to the end of the sliding assembly via screws. The mechanism also includes a pressure sensor. A sliding gap is provided between the top wire block and the sliding assembly. The pressure sensor is fixedly mounted on the end of the sliding assembly, and the side of the pressure sensor away from the sliding assembly abuts against the top wire block. When the top wire block exerts force on the cable, it moves closer to the sliding assembly and presses against the pressure sensor.

[0004] Furthermore, the sliding component has a first fixing groove at its end, the top wire block has a second fixing groove, and the pressure sensor is installed in the first fixing groove and the second fixing groove.

[0005] Furthermore, the top wire block has an arc-shaped groove at the end away from the sliding component, and the cable is placed in the arc-shaped groove.

[0006] Furthermore, the lead screw module includes two mounting blocks, a lead screw, and a rotating block. The two mounting blocks are mounted on a fixed plate at intervals. The lead screw is rotatably connected to the two mounting blocks through bearings. The two mounting blocks are located at the ends of the lead screw near both ends. The rotating block is provided with internal threads and engages with the external threads on the lead screw through the internal threads. The sliding component is fixedly connected to the rotating block by screws.

[0007] Furthermore, the sliding assembly includes an adjusting block group, an adapter plate, and a guide rail. The adjusting block group and the rotating block are fixedly connected by screws. The guide rail is fixedly installed on the fixing plate and located on one side of the lead screw. A guide block is slidably installed on the guide rail, and the guide block is fixedly connected to the adjusting block group through the adapter plate.

[0008] Furthermore, the adjusting block assembly includes a first movable block and a second movable block. The first movable block is fixedly connected to the rotating block by screws. One side of the first movable block is fixedly connected to the adapter plate by screws. The top of the first movable block is provided with a groove perpendicular to the direction of the lead screw axis. The second movable block is slidably installed in the groove and locked by screws. The second movable block slides relatively closer to or further away from the adapter plate along the direction of the groove.

[0009] Furthermore, a thrust detection mechanism for a wire harness also includes a photoelectric sensor, which is fixedly mounted on a fixed plate and located on the side of the lead screw away from the guide rail. The photoelectric sensor is connected to the motor assembly. The photoelectric sensor includes two first sensing blocks spaced apart. A second sensing block is fixedly mounted on the side of the first moving block. When the second sensing block contacts the first sensing block, the motor assembly stops rotating.

[0010] Beneficial effects:

[0011] 1. In this utility model, the arrangement of a fixed plate, motor assembly, lead screw module, sliding assembly, and top wire block enables the reciprocating movement of the top wire block. Combined with the setting of a pressure sensor, the actual thrust value of the thrust detection mechanism acting on the cable can be accurately measured, thereby ensuring the accuracy of the wire harness strength detection. Specifically, when the top wire block comes into contact with the cable, the reaction force of the cable on the top wire block will cause the top wire block to move downward, thereby squeezing the pressure sensor and generating a reading. The reading of the pressure sensor can accurately measure the actual thrust of the thrust detection mechanism on the cable, thereby ensuring the accuracy of the set thrust during wire harness strength detection. This avoids the problem of the wire harness not meeting the strength requirements or the increase in the scrap rate due to the output force of the motor assembly being too small or too large.

[0012] 2. In this utility model, the setting of the first fixing groove and the second fixing groove facilitates the installation and fixing of the pressure sensor, preventing its displacement. In addition, it also ensures that while detecting thrust, the pressure sensor is not damaged due to excessive thrust. Specifically, since the fixing structure of the pressure sensor is located in the first fixing groove and the second fixing groove, when an external force exceeding the pressure sensor's bearing capacity occurs, the ends of the top wire block and the sliding component will form a hard limit to protect the pressure sensor. The setting of the arc groove facilitates the installation and fixing of the cable, preventing the cable from detaching from the top wire block.

[0013] 3. In this utility model, by adjusting the block assembly, the adapter plate and the guide rail, the linear sliding of the top line block can be ensured; by setting the first movable block, the second movable block and the sliding connection between the two, the offset distance of the first movable block relative to the lead screw axis can be appropriately adjusted, thereby ensuring the smooth sliding of the guide block and the guide rail.

[0014] 4. In this utility model, the displacement of the top wire block can be limited by the setting of photoelectric sensor, so as to avoid damage to the wire harness and thrust detection mechanism due to excessive displacement. Attached Figure Description

[0026] This utility model provides a thrust detection mechanism for wire harnesses, such as... Figure 1 and Figure 2 As shown, the assembly includes a fixed plate 61, a motor assembly 62, a lead screw module 63, a sliding assembly 64, and a top wire block 65. The motor assembly 62 is fixedly mounted on the fixed plate 61, and its output shaft is connected to the lead screw module 63 via a coupling 8. The motor assembly 62 includes a motor 621 and a reducer 622, which are connected by a flange and fixedly mounted on the fixed plate 61. The lead screw module 63 specifically includes two mounting blocks, a lead screw, and a rotating block. The two mounting blocks are spaced apart on the fixed plate 61, and the lead screw is rotatably connected to the two mounting blocks via bearings. The two mounting blocks are located at the ends of the lead screw near both ends. The rotating block has an internal thread and is connected to the lead screw via the internal thread. The external thread on the screw is engaged, and the sliding component 64 is fixedly connected to the rotating block by screws. The sliding component 64 is slidably connected to the fixed plate 61 and reciprocates along the axis of the lead screw under the drive of the rotating block and the lead screw thread engagement. The top wire block 65 is connected to the end of the sliding component 64 by screws. It also includes a pressure sensor 66. There is a sliding gap between the top wire block 65 and the sliding component 64. The pressure sensor 66 is fixedly installed on the end of the sliding component 64, and the side of the pressure sensor 66 away from the sliding component 64 abuts against the top wire block 65. When the top wire block 65 exerts force on the cable, the top wire block 65 moves closer to the sliding component 64 and squeezes the pressure sensor 66.

[0027] In this embodiment, the arrangement of the fixed plate 61, motor assembly 62, lead screw module 63, sliding assembly 64, and top wire block 65 enables the reciprocating movement of the top wire block 65. Combined with the pressure sensor 66, the actual thrust value of the thrust detection mechanism acting on the cable can be accurately measured, thereby ensuring the accuracy of the wire harness strength detection. Specifically, when the top wire block 65 comes into contact with the cable, the reaction force of the cable on the top wire block 65 will cause the top wire block 65 to move downward, thereby squeezing the pressure sensor 66 and generating a reading. The reading of the pressure sensor 66 can accurately measure the actual thrust of the thrust detection mechanism on the cable, thereby ensuring the accuracy of the set thrust during wire harness strength detection. This avoids the problem of the wire harness not meeting the strength requirements or the increase in the scrap rate due to the output force of the motor assembly 62 being too small or too large.

[0028] Working principle: such as Figure 1 and Figure 2 As shown, the terminals and cables are first fixed by clamps. Then, the motor 621 is started and the top wire block 65 is raised by the lead screw and rotating block, so that the end of the top wire block 65 abuts against the cable and pushes the cable to move. The output power of the motor 621 is adjusted by the measurement data of the pressure sensor 66 to ensure that the measurement data is equal to the set thrust of the strength test. When the set thrust cannot push the cable away, it is determined that the wire harness strength meets the standard. Conversely, when the set thrust pushes the cable away, it is determined that the wire harness strength does not meet the standard.

[0029] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the sliding component 64 has a first fixing groove at its end, the top wire block 65 has a second fixing groove, and the pressure sensor 66 is installed in the first fixing groove and the second fixing groove.

[0030] In this embodiment, the first and second fixing slots facilitate the installation and fixation of the pressure sensor 66, preventing its displacement. They also ensure that the pressure sensor 66 is not damaged by excessive thrust while detecting thrust. Specifically, since the fixing structure of the pressure sensor 66 is located in the first and second fixing slots, when an external force exceeding the pressure sensor 66's bearing capacity occurs, the ends of the top wire block 65 and the sliding component 64 will form a hard limit to protect the pressure sensor 66.

[0031] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the top wire block 65 has an arc-shaped groove at one end away from the sliding component 64, and the cable is placed in the arc-shaped groove.

[0032] In this embodiment, the arc-shaped groove facilitates the installation and fixation of the cable, preventing the cable from detaching from the top cable block 65.

[0033] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the sliding assembly 64 includes an adjusting block group 641, an adapter plate 642, and a guide rail 643. The adjusting block group 641 is fixedly connected to the rotating block by screws. The guide rail 643 is fixedly installed on the fixing plate 61 and located on one side of the lead screw. A guide block is slidably installed on the guide rail 643. The guide block is fixedly connected to the adjusting block group 641 through the adapter plate 642. The adjusting block group 641 includes a first movable block and a second movable block. The first movable block is fixedly connected to the rotating block by screws. One side of the first movable block is fixedly connected to the adapter plate 642 by screws. The top of the first movable block is provided with a groove perpendicular to the axis of the lead screw. The second movable block is slidably installed in the groove and locked by screws. The second movable block slides relatively closer to or further away from the adapter plate 642 along the direction of the groove.

[0034] In this embodiment, by adjusting the arrangement of the block group 641, the adapter plate 642 and the guide rail 643, the linear sliding of the top wire block 65 can be ensured; by adjusting the arrangement of the first movable block, the second movable block and the sliding connection between the two, the offset distance of the first movable block relative to the lead screw axis can be appropriately adjusted, thereby ensuring the smooth sliding of the guide block and the guide rail 643.

[0035] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, a thrust detection mechanism for a wire harness also includes a photoelectric sensor 67, which is fixedly mounted on a fixed plate 61 and located on the side of the lead screw away from the guide rail 643. The photoelectric sensor 67 is connected to the motor assembly 62. The photoelectric sensor 67 includes two first sensing blocks spaced apart. A second sensing block is fixedly mounted on the side of the first moving block. When the second sensing block contacts the first sensing block, the motor assembly 62 stops rotating.

[0036] In this embodiment, the displacement of the top wire block 65 can be limited by the photoelectric sensor 67, thus preventing damage to the wire harness and thrust detection mechanism due to excessive displacement.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
