[0001] This utility model relates to the field of fixture technology, specifically to a fixture mechanism that is easy to replace. Background Technology

[0002] Fixtures are a broad category of tools used in woodworking, metalworking, fitter work, machinery, electrical control, and other handicrafts. They are primarily used to assist in controlling position or movement. Fixtures can be divided into three categories: process assembly fixtures, project testing fixtures, and circuit board testing fixtures.

[0003] In the field of wire harness processing, jigs are essential tools for fixing, positioning, and assisting in the processing of wire harnesses. With the diversification of market demands, the sizes and specifications of wire harnesses requiring processing are increasing. Traditional jigs have significant drawbacks when dealing with wire harness processing tasks of different sizes; because the placement area cannot be adjusted, accurate and stable placement cannot be achieved for wire harnesses of mismatched sizes. Therefore, a jig mechanism that is easy to replace is proposed. Utility Model Content

Example

[0020] Please see Figure 1-5 This utility model provides a technical solution: a fixture mechanism that is easy to replace, including a base 1, a guide rod 4 fixed to the top of the base 1, a support rod 7 fixed to the top of the guide rod 4, and a cylinder 8 fixed to the top of the support rod 7; the cylinder 8 can be activated by adding a two-hand start button or a light grid (not shown in the figure) to prevent accidental pinching of hands; a placement rack 3 is provided on the top of the base 1, and several placement slots are opened on the top of the placement rack 3 for placing wire harnesses. After the wire harness is placed inside the placement slot, the pressure plate 5 and the rubber layer 6 are pushed by the push rod end of the cylinder 8 to clamp the wire harness, which can be used for further processing of the wire harness, such as adding buckles, installing shielding rings or affixing labels. Alternatively, this fixture can be placed at one end of a crimping device and used in conjunction with a terminal crimping machine to assist the wire harness in the terminal crimping process; the pressure plate 5 is fixed to the push rod end of the cylinder 8, and the bottom of the pressure plate 5 is bonded with a rubber layer 6. The pressure plate 5 is slidably connected to the outside of the guide rod 4 through a linear bearing.

[0021] A connecting component 2 is provided on one side of the base 1. The connecting component 2 is used for the disassembly and replacement of the placement rack 3. Different placement racks 3 have different sized placement slots on their tops, which can be used to process wire harnesses of different sizes. When it is necessary to replace the placement rack 3 to handle wire harnesses of different sizes, quick disassembly and assembly can be achieved by operating the connecting component 2. The positions and spacing of the locking slots 27 at the bottom of multiple placement racks 3 are standardized to ensure compatibility with the connecting component 2.

[0022] The connecting assembly 2 includes a slide rod 21 and two connecting frames 24. Several locking rods 25 are fixed to one side of each connecting frame 24, and a guide block 212 is fixed to the other side. A second inclined surface 213 is provided on one side of the guide block 212. A protrusion 29 is fixed to one end of the slide rod 21, and both sides of the protrusion 29 have first inclined surfaces 28. Under normal conditions, the connecting frame 24 moves inward under the elastic force of the first spring 22, causing the locking rods 25 to insert into the locking groove 27 at the bottom of the placement frame 3. At this time, the placement frame 3 is fixed in the limiting groove 26 of the base 1 and cannot move. Magnets are installed on both the locking rods 25 and the inner walls of the locking groove 27, and the magnetic poles of the two magnets are opposite to increase the magnetic attraction force, preventing the locking rods 25 from coming out after vibration. The attraction force is ≥2 N.

[0023] The connecting frame 24 is L-shaped. A limiting groove 26 is provided on the top of the base 1. The outer side of the placement frame 3 is fitted into the inner side of the limiting groove 26. A second sliding groove 210 is provided inside the base 1. Two first sliding grooves 23 are provided on the inner wall of the second sliding groove 210. When the placement frame 3 needs to be replaced, the sliding rod 21 is pushed inward. As the sliding rod 21 slides, it moves the protrusion 29, compressing the second spring 211. The first inclined surface 28 of the protrusion 29 engages with the second inclined surface 213 of the guide block 212 on the connecting frame 24. The first inclined surface 28 pushes the second inclined surface 213, causing the two connecting frames 24 to slide outward along the first sliding groove 23, compressing the first spring 22. As the connecting frame 24 moves outward, the locking rod 25 disengages from the locking groove 27 of the placement frame 3. Once the locking rod 25 is completely disengaged, the placement frame 3 can be removed from the limiting groove 26.

[0024] The placement rack 3 has several locking slots 27 on both sides of its bottom. When the locking rod 25 is inserted into the locking slot 27, the placement rack 3 is in a fixed state. When the locking rod 25 leaves the locking slot 27, the placement rack 3 is in a replaceable state. When the elastic force of the first spring 22 pushes the connecting frame 24 to slide along the first slide groove 23, the locking rod 25 fixed on one side of the connecting frame 24 is inserted into the locking slots 27 on both sides of the bottom of the placement rack 3. At the same time, the outer side of the placement rack 3 is adapted to the limiting groove 26 on the top of the base 1. With double positioning, the placement rack 3 is stably fixed on the top of the base 1, providing a solid foundation for subsequent wire harness placement.

[0025] Inside the base 1, a first spring 22 is connected between the first slide groove 23 and the connecting frame 24, and a second spring 211 is connected between the protrusion 29 and the inner wall of the second slide groove 210. Both springs are in a pre-compressed state, storing elastic potential energy to provide power for the movement of subsequent components. The first inclined surface 28 and the second inclined surface 213 are inclined and engaged. The second spring 211 is connected to the inner wall of the protrusion 29 and the second slide groove 210. The connecting frame 24 is slidably connected to the inner side of the first slide groove 23. The first spring 22 is connected between the first slide groove 23 and the connecting frame 24. If the second spring 211 is aged or has insufficient elasticity, the aged spring can be replaced directly by removing the cover plate at the bottom of the base 1, which is connected by bolts. After replacement, the cover plate can be reinstalled to ensure the stable operation of the mechanism. The slide rod 21 is slidably inserted into one side of the base 1. The bottom of the base 1 is connected by bolts to cover plates located on the side of the first spring 22 and the second spring 211 respectively. The first spring 22 and the second spring 211 can be replaced by removing the cover plates. The spring has a certain compression, which gives the spring a certain elastic potential energy.

[0026] Working principle: The wire harness to be processed is placed into the placement slot at the top of the placement frame 3. The shape and size of the placement slot are adapted to the corresponding wire harness to ensure that the wire harness does not shift during processing. The cylinder 8 is activated, and the push rod end of the cylinder 8 extends downward, pushing the pressure plate 5, which is fixedly connected to it, to move. Since the pressure plate 5 is slidably connected to the outside of the guide rod 4 through a linear bearing, and the guide rod 4 is fixed to the top of the base 1, the pressure plate 5 moves horizontally downward under the guidance of the guide rod 4 until the rubber layer 6 bonded to the bottom of the pressure plate 5 is in close contact with the wire harness. The rubber layer 6 not only avoids damage to the wire harness due to excessive clamping force, but also enhances friction to prevent the wire harness from slipping. At this time, the wire harness is stably clamped and can proceed to the next processing step, such as adding clips, installing shielding rings, and affixing labels. If this fixture is placed at one end of the crimping equipment, it can also be used in conjunction with a terminal crimping machine to assist the wire harness in completing the terminal crimping process. When processing wire harnesses of different sizes, the placement rack 3 with the corresponding size slot needs to be replaced. At this time, the slide rod 21 is pushed inward to the base 1. The protrusion 29 fixed at one end of the slide rod 21 slides along the second slide groove 210 with the slide rod 21, while compressing the second spring 211, increasing the elastic potential energy of the second spring 211. The first inclined surfaces 28 on both sides of the protrusion 29 form an inclined surface fit with the second inclined surface 213 on the guide block 212 fixed on the other side of the connecting frame 24. As the protrusion 29 continues to move, the first inclined surface 28 generates a lateral pushing force on the second inclined surface 213, pushing the connecting frame 24 to overcome the elastic force of the first spring 22 and slide away from the placement rack 3 along the first slide groove 23. During the sliding process of the connecting frame 24, the locking rod 25 on one side gradually disengages from the locking groove 27 at the bottom of the placement rack 3. At this time, the placement rack 3 is released from fixation and is in a replaceable state.

[0027] The staff can remove the old placement rack 3 and place the new placement rack 3 with the corresponding size placement slot into the limiting slot 26 at the top of the base 1. Then, the slide bar 21 is released, the second spring 211 releases its elastic potential energy to push the protrusion 29 to reset, the first spring 22 pushes the connecting frame 24 to reset, and the locking rod 25 is inserted into the locking slot 27 of the new placement rack 3 again, thus completing the replacement of the placement rack 3.

[0028] In summary, the cylinder 8 pushes the pressure plate 5 to move. The pressure plate 5 is slidably connected to the outside of the guide rod 4 through a linear bearing. Under the guidance of the guide rod 4, the pressure plate 5 moves horizontally downward, so that the wire harness can be stably clamped. After the wire harness is stably clamped, various subsequent processing steps can be performed, making it applicable to a wide range of scenarios.

[0029] When different sizes of wire harnesses need to be processed, the placement rack 3 with the corresponding size placement slot is replaced. The process of replacing the placement rack 3 is simple. Just push the slide bar 21 inward to the base 1. The inclined surface of the protrusion 29 and the guide block 212, as well as the elastic action of the second spring 211 and the first spring 22, allow the locking bar 25 to be inserted into or removed from the locking groove 27 at the bottom of the placement rack 3. This achieves quick replacement and stable fixation of the placement rack 3 without complicated tools and cumbersome steps, saving time and improving work efficiency.
