[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] like Figure 1 As shown in the figure, this application embodiment provides a three-coordinate box-type assembly fixture, which includes: a positioning base 1, a first positioning component 6, a second positioning component 10, and a third positioning component 3; wherein,

[0042] Positioning protrusions 2 are provided on both sides of the top corners of the positioning base 1 away from the first positioning component 6 and the second positioning component 10;

[0043] The first positioning component 6, the second positioning component 10, and the third positioning component 3 are respectively located in the X-axis direction, Y-axis direction, and Z-axis direction of the positioning base 1;

[0044] The first positioning component 6, the second positioning component 10, and the third positioning component 3 each include a first positioning unit 61 that can move linearly along the X-axis, a second positioning unit 101 that can move along the Y-axis, and a third positioning unit 31 that can move along the Z-axis.

[0045] In this embodiment, the three-coordinate box-type assembly fixture mainly consists of four parts: a positioning base 1, a first positioning component 6, a second positioning component 10, and a third positioning component 3. The positioning base 1 serves as an assembly platform for box-type parts, while the first positioning component 6, the second positioning component 10, and the third positioning component 3 position the box-type parts along the X-axis, Y-axis, and Z-axis, respectively. Specifically, the part to be assembled can be placed on the positioning base 1 manually or by a robotic arm. The first positioning unit 61 on the first positioning component 6 moves along the X-axis toward the part to be assembled, and simultaneously, the second positioning unit 101 on the second positioning component 10 moves along the Y-axis toward the part to be assembled. Because positioning protrusions 2 are provided on both sides of the top corner of the positioning base 1 away from the first positioning component 6 and the second positioning component 10, and these protrusions are arranged in two sets on either side of the top corner of the positioning base 1, corresponding to the first positioning unit 61 and the second positioning unit 101 respectively, with the two sets of protrusions 2 arranged perpendicularly to each other, this fixture is more suitable for positioning the corners of box-type parts. Therefore, corner positioning can be used to achieve the horizontal positioning of the parts to be assembled. Specifically, the first positioning unit 61 and the second positioning unit 101 respectively push the parts to be assembled forward along the X-axis and Y-axis to the corresponding positioning protrusions 2. Under the combined action of the two sets of positioning protrusions 2, the first positioning unit 61, and the second positioning unit 101, the horizontal positioning and fixing of the parts to be assembled is completed. This embodiment uses corner positioning, which has the advantages of large tolerance for the position of the pre-loading material, simple and quick positioning, adaptability to manual or semi-automatic assembly of parts of various sizes, and fully automatic assembly of parts of the same size.

[0046] Once the horizontal position of the part to be assembled is determined, the third positioning unit 31 on the third positioning assembly 3 can be controlled to move downward, applying downward pressure to the part to be assembled, thereby positioning the part on the Z-axis. In addition to having a separate positioning function, the third positioning unit 31 also has the functions of pressing the upper and lower boxes together, or pressing the intermediate part and the lower box together, or both.

[0047] In this embodiment, the first positioning unit 61, the second positioning unit 101, and the third positioning unit 31 can be driven by a linear displacement drive mechanism, such as a hydraulic cylinder, a pneumatic cylinder, or a lead screw. The control of the maximum movement position of the first positioning unit 61, the second positioning unit 101, and the third positioning unit 31 can be achieved by a limit switch or a PLC control system.

[0048] like Figure 1 As shown, the first positioning component 6, the second positioning component 10 and the third positioning component 3 also include a first positioning guide post 12 arranged along the X-axis direction, a second positioning guide post 11 arranged along the Y-axis direction and a third positioning guide post 4 arranged along the Z-axis direction, respectively.

[0049] The first positioning unit 61 is slidably disposed on the first positioning guide post 12, the second positioning unit 101 is slidably disposed on the second positioning guide post 11, and the third positioning unit 31 is slidably disposed on the third positioning guide post 4.

[0050] Specifically, it should be noted that the first positioning guide post 12, the second positioning guide post 11, and the third positioning guide post 4 serve as sliding tracks for the first positioning unit 61, the second positioning unit 101, and the third positioning unit 31, respectively. These tracks act as the basis for the movement of the corresponding positioning units and guide their movement, improving the accuracy of the positioning unit's motion. The first positioning unit 61, the second positioning unit 101, and the third positioning unit 31 are slidably mounted on their respective positioning guide posts.

[0051] like Figure 1 As shown, the first positioning guide post 12, the second positioning guide post 11 and the third positioning guide post 4 have the same structure, all of which are two double-ended screws;

[0052] The first end of the double-ended screw is threaded to the positioning base 1, and the second end is threaded to a stop block and / or an anti-loosening nut.

[0053] Specifically, it should be noted that, to facilitate the installation of the first positioning guide post 12, the second positioning guide post 11, and the positioning base 1, this embodiment uses double-ended screws for the first positioning guide post 12 and the second positioning guide post 11. The middle part of the double-ended screw is a smooth rod-shaped structure, and both ends are provided with external threads. When installing the double-ended screw, its first thread can be screwed into the positioning base 1. To restrict the rotational movement of the first positioning unit 61 and the second positioning unit 101, in this embodiment, both the first positioning guide post 12 and the second positioning guide post 11 are composed of two double-ended screws. The two double-ended screws can be arranged side by side in the horizontal direction or side by side in the vertical direction. To reduce the volume, it is preferable to arrange them side by side in the horizontal direction.

[0054] To prevent the first positioning unit 61 from detaching from the first positioning guide post 12 during movement, and to prevent the second positioning unit 101 from detaching from the second positioning guide post 11 during movement, a stop or anti-loosening nut is installed at the end of the corresponding double-ended screw away from the positioning base 1. Due to the threaded structure of the double-ended screw, the installation of the anti-loosening nut and the stop is convenient.

[0055] To prevent the connection between the double-ended screw and the positioning base 1 from loosening, the end of the double-ended screw that is threaded to the positioning base 1 is coated with thread-locking adhesive, which can be used to unscrew it by local heating during disassembly.

[0056] like Figure 1As shown, it also includes a drive mechanism for driving the first positioning unit 61, the second positioning unit 101 and the third positioning unit 31 to move along the axial direction of the double-ended screw. The drive mechanism is set to any one of a cylinder, a hydraulic cylinder and a lead screw linear displacement mechanism.

[0057] Furthermore, the first positioning unit 61 and the second positioning unit 101 have the same structure, both including a horizontal slider 612 that is slidably connected to the double-ended screw.

[0058] The horizontal slider 612 can move toward the positioning base 1 and press against the part located on the positioning base 1.

[0059] Specifically, it should be noted that the horizontal slider 612 is a movable structure mounted on the corresponding double-ended screw. The horizontal slider 612 can be moved manually or automatically by the drive mechanism. When the horizontal slider 612 moves toward the positioning base 1 and pushes the part to be assembled, a horizontal thrust can be applied to the part to be assembled. This horizontal thrust includes the thrust along the X-axis and the thrust along the Y-axis. Under the action of this thrust, the two sides of the top corner of the part to be assembled can be tightly attached to the positioning protrusion 2 on the positioning base 1, thereby realizing the corner positioning of the part to be assembled.

[0060] like Figure 1 As shown, both the first positioning unit 61 and the second positioning unit 101 further include a following positioning block 611 disposed on the horizontal slider 612. The following positioning block 611 can move toward the positioning base 1 and press against the part located on the positioning base 1. The upper end of the following positioning block 611 is provided with a loading groove 6110 for loading the part to be assembled; the end of the following positioning block 611 facing the positioning base 1 is provided with a pressing protrusion 7.

[0061] Specifically, it should be noted that the accompanying positioning block 611 is mounted on the horizontal slider 612, and the number of accompanying positioning blocks 611 is the same as the number of horizontal sliders 612. The accompanying positioning block 611 can be configured in different structural forms as needed. Its function is to load parts using the loading slot 6110 and perform locking assembly, or simply to fix the reference part. The horizontal accompanying positioning block 611 is not necessarily necessary. In particular, when only the reference part needs to be fixed, the horizontal slider 612 can replace the function of the accompanying positioning block 611, eliminating the need for the accompanying positioning block 611. The specific configuration can be determined according to the actual application scenario.

[0062] When the accompanying positioning block 611 is close to the reference part, the top pressing protrusion 7 located at the end of the accompanying positioning block 611 can press against the reference part, improving the stability and accuracy of the positioning of the reference part.

[0063] like Figure 1 As shown, the third positioning unit 31 includes a vertical slider 311 that is slidably connected to a double-ended thread and a pressure block 312 disposed on the vertical slider 311.

[0064] Specifically, it should be noted that the structure of the vertical slider 311 is similar to that of the horizontal slider 612, differing only in their direction of movement. The vertical slider 311 is primarily used for sliding up and down in the Z-axis direction, thereby driving the pressure block 312 to slide up and down synchronously. The pressure block 312, as a variant of the accompanying positioning block 611, is used to press the upper and lower boxes together, or to press the intermediate part against the lower box, or both. When the pressure block 312 slides downwards with the vertical slider 311, it applies downward pressure to the upper end of the part to be assembled, thereby completing part positioning and installation.

[0065] like Figure 1 As shown, positioning claws 313 are provided on both sides of the lower end of the pressure block 312, and the positioning claws 313 match the corners on both sides of the part to be assembled.

[0066] For manual assembly, when the part to be assembled moves downwards (in the negative Z direction), it can first be matched with the positioning claw 313 at the lower end of the pressure block 312 at its corners before proceeding downwards, which can improve the accuracy and consistency of the assembly. The overall shape of the pressure block 312 can be "U" shaped, with its two protruding ends facing away from the vertical slider 311 and serving as two pins of the pressure block 312, which can be pressed against the upper end of the part during assembly. The material of the pressure block 312 can be rigid or flexible. When the assembly connection method is a tight fit or adhesive bonding, a rigid material is more suitable; when the assembly connection method is a snap-fit, a flexible material is more suitable. In this case, the two pins of the pressure block 312 can be snapped and pressed sequentially or simultaneously under the action of external force.

[0067] To facilitate the installation of the accompanying positioning block 611 and the horizontal slider 612, a mounting groove 9 is provided at the upper end of the horizontal slider 612, and the mounting groove 9 is set perpendicular to the moving direction of the horizontal slider 612; a retaining strip is provided at the lower end of the accompanying positioning block 611, and the retaining strip is slidably disposed within the mounting groove 9. The mounting groove 9 allows the accompanying positioning block 611 to be quickly installed on the horizontal slider 612, and makes it easier to replace different accompanying positioning blocks 611 according to the requirements of the parts to be assembled. The accompanying positioning block 611 can be locked on the horizontal slider 612 by bolt locking or by increasing friction.

[0068] To facilitate fixing the horizontal slider 612 to the double-ended screw, a push rod 8 is threadedly connected to one side of both the horizontal slider 612 and the vertical slider 311. The first end of the push rod 8 is in contact with the double-ended screw, and the second end extends out to the corresponding horizontal slider 612 or vertical slider 311.

[0069] A standard long bolt can be selected as the push rod 8. The second end of the push rod 8 is designed as a handle mechanism that is more suitable for manual operation. Its function is to screw the push rod 8 in so that it presses against the double-ended screw, so that the horizontal slider 612 stops at the selected position. After the push rod 8 is screwed out, the horizontal slider 612 returns to the free motion state (axial upward). The push rod 8 is similar to the function of a motion switch.

[0070] like Figure 1 As shown, the three-coordinate box-type assembly fixture also includes three limiting pins 5 on the positioning base 1. The three limiting pins 5 correspond to two horizontal sliders 612 and one vertical slider 311, respectively, and are used to limit the minimum distance between the horizontal sliders 612 and the vertical slider 311 and the positioning base 1.

[0071] Specifically, it should be noted that the limiting pin 5, as a hard limiting structure of the horizontal slider 612, is used to limit the minimum distance between the horizontal slider 612 and the vertical slider 311 and the positioning base 1, so as to prevent the horizontal slider 612 from colliding with the positioning base 1 after exceeding its travel range.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
