[0025] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0026] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0028] An embodiment of this utility model provides an assembly positioning fixture, such as... Figure 1-4 As shown, it includes:

[0029] Work platform 1;

[0030] The first positioning structure 2 includes a base plate 201 disposed on the working platform 1, a first positioning seat 202 disposed on the base plate 201, a second positioning seat 203 disposed on the base plate 201, and a drive structure 204 connected to the base plate 201.

[0031] The second positioning structure 3 includes a first pressing structure 301 disposed on the rear side of the first positioning seat 202 and a second pressing structure 302 disposed on the front side of the second positioning seat 203. The first pressing structure 301 is used to press the first workpiece 501 placed on the first positioning seat 202 toward the direction of approaching the second positioning seat 203, and the second pressing structure 302 is used to press the second workpiece 502 placed on the second positioning seat 203 toward the direction of approaching the first positioning seat 202.

[0032] The third positioning structure 4 is set on the working platform 1. The third positioning structure 4 includes a pressing structure 401 set on one side of the first positioning structure 2. The pressing structure 401 is used to limit the lateral position of the fastener 6. The driving structure 204 is used to move the first positioning structure 2 away from or closer to the third positioning structure 4.

[0033] Although there are errors in the bending process of the first workpiece 501 and the second workpiece 502, the distance between the connecting holes on the left and right sides for inserting the fastener 6 and the ends of the side plates is fixed during processing. Based on this, the first pressing structure 301 and the second pressing structure 302 are set to press the first workpiece 501 and the second workpiece 502 against the second positioning seat 203 and the first positioning seat 202 on the opposite side, respectively. The ends abut against the structure on the opposite positioning seat. Positioning is achieved by using the ends of the first side plate 504 and the second side plate 505 as positioning references, realizing the alignment of the holes of each connecting hole, ensuring the position of the connecting holes of the two workpieces during assembly, and facilitating the accurate insertion of the fastener 6. Specifically, the first positioning seat 202 and the second positioning seat 203 have positioning structures that abut against the ends of the workpieces to determine the position of the connecting holes. The setting of the positioning seats provides a fixed base for the first workpiece 501 and the second workpiece 502. Combined with the design of the first pressing structure 301 and the second pressing structure 302, the problem of low hole alignment accuracy at the connection point when the fastener 6 is inserted is solved.

[0034] The driving structure 204 allows the first positioning structure 2 to move relative to the third positioning structure 4, facilitating the assembly of the fastener 6 without being affected by the third positioning structure 4. Specifically, the driving structure 204 can drive the first positioning structure 2 to move upward, downward, or laterally at an angle, achieving the effect of installing the fastener 6 away from the third positioning structure 4. After the fastener 6 is assembled, the driving structure 204 drives the first positioning structure 2 to reset. At the same time, the pressing structure 401 of the third positioning structure 4 will directly abut against the end of the fastener 6, effectively limiting the lateral position of the fastener 6, facilitating the assembly of other workpieces subsequently, and improving the stability of the installation. Specifically, the pressing structure 401 can use spring force, external driving pressing, or snap-locking to abut and tighten the fastener 6, ensuring stable pressure during subsequent assembly of the fastener 6 and preventing detachment.

[0035] In some embodiments, such as Figure 2-4 As shown, the first pressing structure 301 includes a first push plate 303 disposed on the rear side of the first positioning seat 202, a first top plate 304 disposed on the rear side of the first push plate 303, and a first spring structure 305 connecting the first push plate 303 and the first top plate 304; the second pressing structure 302 includes a second push plate 306 disposed on the front side of the second positioning seat 203, a second top plate 307 disposed on the front side of the second push plate 306, and a second spring structure 308 connecting the second push plate 306 and the second top plate 307.

[0036] Both the first pressing structure 301 and the second pressing structure 302 adopt a combination of push plate, top plate and spring structure. The elastic force of the spring realizes flexible pressing of the workpiece and applies uniform pressure to the horizontal plate 503 of the workpiece, so that the first side plate 504 and the second side plate 505 of the workpiece can abut against the positioning seat on the opposite side, so as to stably align the connecting hole.

[0037] Furthermore, such as Figure 2 As shown, the first pressing structure 301 includes a first guide rail structure 309 disposed at the bottom of the first push plate 303, and the bottom of the first push plate 303 is provided with a first guide slide portion that matches the first guide rail structure 309; the second pressing structure 302 includes a second guide rail structure 311 disposed at the bottom of the second push plate 306, and the bottom of the second push plate 306 is provided with a second guide slide portion that matches the second guide rail structure 311.

[0038] The first clamping structure 301 and the second clamping structure 302 achieve stable movement and precise positioning of the push plate through the cooperation of the first guide rail structure 309 with the first guide slide and the second guide rail structure 311 with the second guide slide, respectively. Specifically, the first guide rail structure 309 and the second guide rail structure 311 are both guide rails arranged in the front-back direction. The arrangement of the guide rail structure ensures the stability and accuracy of the first push plate 303 and the second push plate 306 in the process of clamping the horizontal plate 503, and enhances the stability and reliability of the fixture.

[0039] In some embodiments, such as Figure 2-3 As shown, the first positioning seat 202 includes a first base 205 for placing the first workpiece 501 and a first limiting block 206 and a second limiting block 207 disposed on the first base 205. The second positioning seat 203 includes a second base 208 for placing the second workpiece 502 and a third limiting block 209 and a fourth limiting block 210 disposed on the second base 208. The first limiting block 206 is used to abut against the first side plate 504 of the second workpiece 502, the second limiting block 207 is used to abut against the second side plate 505 of the second workpiece 502, the third limiting block 209 is used to abut against the first side plate 504 of the first workpiece 501, and the fourth limiting block 210 is used to abut against the second side plate 505 of the first workpiece 501.

[0040] The advantage of this structure is that the first positioning seat 202 and the second positioning seat 203 provide a stable foundation for the workpiece through the first base 205 and the second base 208, respectively. At the same time, the first limiting block 206, the second limiting block 207, the third limiting block 209 and the fourth limiting block 210 abut and limit the ends of the side plates of each workpiece, ensuring the positional accuracy of the connecting holes of the workpiece during the assembly process. This effectively solves the assembly problem caused by workpiece processing errors, improves assembly efficiency and quality, and enhances the stability and reliability of the fixture.

[0041] Furthermore, such as Figure 3 As shown, both the first push plate 303 and the second push plate 306 include a Z-shaped abutment portion 313 for pushing the workpiece and a connecting portion provided at the lower part of the abutment portion 313 for connecting the spring structure.

[0042] Specifically, the height of the abutment part 313 may vary depending on the workpiece. The Z-shaped abutment part 313 is designed so that its upper end effectively abuts against the horizontal plate 503 of the workpiece, while the lower end is used to connect with the first spring structure 305 or the second spring structure 308, which is convenient to be pushed by the spring and enhances the adaptability to workpieces of different sizes. The abutment part 313 can be detachably installed.

[0043] Furthermore, such as Figure 3 As shown, a fifth limiting block 211 is provided on the first base 205. The fifth limiting block 211 is used to limit the lateral displacement of the first workpiece 501.

[0044] In practice, due to the installation method of the first workpiece 501 and the second workpiece 502, the order of the structure from right to left after the workpieces are installed is: the third positioning structure 4, the fastener 6, the first side plate 504 of the second workpiece 502, the second side plate 505 of the first workpiece 501, the second side plate 505 of the second workpiece 502, the first side plate 504 of the first workpiece 501, and then the fifth limiting block 211. Of course, the fifth limiting block 211 can also be set in other places that can abut against the first workpiece 501. Since the fastener 6 will be pushed and tightened by the third positioning structure 4, the fifth limiting block 211 can limit the lateral displacement of the entire structure by limiting the lateral displacement of the first workpiece 501, thereby improving the reliability and quality of the entire assembly process.

[0045] In some embodiments, such as Figure 4 As shown, the drive structure 204 includes a lifting part 213 connected to the base plate 201 and disposed below the working platform 1, a drive part 212 for pushing the lifting part 213 to move up and down, and a guide part 214 disposed on the base plate 201.

[0046] The drive unit 212 is specifically a pneumatic or hydraulic drive device, and the lifting unit 213 is a driven telescopic rod that enables precise movement and position adjustment of the base plate 201, ensuring that the first positioning structure 2 can move accurately relative to the third positioning structure 4. The upward lifting method facilitates the insertion of fasteners 6 by material handling devices such as robotic arms. The guide unit 214 enables the first positioning structure 2 and the second positioning structure 3 to move along the required path during the upward movement, improving the stability of the driven up and down movement.

[0047] In some embodiments, such as Figure 4As shown, the third positioning structure 4 includes a fixed plate 402 disposed on the working platform 1, and the top pressing structure 401 includes a top block fixing block 403 disposed on the fixed plate 402, a top block 404 disposed in the top block fixing block 403, and a third spring structure 405. The top block fixing block 403 has a receiving groove for accommodating the top block 404. One end of the third spring structure 405 is connected to the top block 404, and the other end is connected to the receiving groove.

[0048] The third spring structure 405 provides a stable pressure for the top pressing structure 401, ensuring that the top block 404 abuts against and presses the fastener 6, thereby achieving stable pressure on the end of the fastener 6, ensuring the stability and reliability of the pressure, effectively limiting the lateral position of the fastener 6, and improving the stability of subsequent installation. The top block 404 can be limited to lateral displacement by the third spring structure 405 or the top block fixing block 403.

[0049] Furthermore, such as Figure 4 As shown, the top block fixing block 403 is provided with a first threaded structure 407 on its periphery, and the fixing plate 402 is provided with a second threaded structure 408 that cooperates with the first threaded structure 407. The first threaded structure 407 is used to rotate and adjust the lateral position of the top block fixing block 403 on the fixing plate 402.

[0050] The rotating top block fixing block 403 can be easily adjusted in its lateral position on the fixing plate 402 via the first threaded structure 407, and the extension length of the top block 404 can be adjusted by rotation, thereby adjusting the distance between the top block 404 and the end of the fastener 6 to accommodate fasteners 6 of different specifications and sizes. In this embodiment, the rotating top block fixing block 403 is pressed down and tightened by the fastening structure 409 to prevent rotation, and its displacement can also be limited by other structures.

[0051] Furthermore, the top block 404 has a spherical structure, and the diameter of the hole at the end of the top block fixing block 403 is smaller than the diameter of the top block 404.

[0052] The top block 404 has a spherical structure, ensuring that the contact position of the top block 404 will not change regardless of the rotation of the top block fixing block 403, thus improving the assembly accuracy and reliability. The end of the top block fixing block 403 with a smaller end diameter than the top block 404 is closer to the workpiece, and the receiving groove at the end gradually decreases in size, which can effectively prevent the top block 404 from accidentally falling off during the contact process, enhancing the stability and safety of the top pressing structure 401.

[0053] Communication transmission equipment is a crucial carrier of information transmission, and its sophisticated frame structure is the foundation for ensuring stable operation. For example... Figure 1The frame shown consists of a first workpiece and a second workpiece installed opposite each other and connected by fasteners. Both the first workpiece and the second workpiece have a horizontal plate, a first side plate and a second side plate. The connecting hole is located on one end of the first side plate and the second side plate. Due to the length error caused by bending, the connecting hole of the first workpiece and the second workpiece will have an alignment error when placed in a conventional way. In addition, in order to ensure a stable connection, the fasteners need to be pressed after insertion to provide a stable foundation for subsequent assembly.

[0054] Communication transmission equipment is a crucial carrier of information transmission, and its sophisticated frame structure is the foundation for ensuring stable operation. For example... Figure 1 The frame shown consists of a first workpiece 501 and a second workpiece 502 mounted opposite each other and connected by fasteners 6. Both the first workpiece 501 and the second workpiece 502 have a horizontal plate 503, a first side plate 504 and a second side plate 505. The connecting holes are located on one side of the end of the first side plate 504 and the second side plate 505. Due to the length error that will occur during bending processing, the conventional placement method will result in the problem of misalignment of the connecting holes of the first workpiece 501 and the second workpiece 502. Moreover, in order to ensure a stable connection, the fasteners 6 need to be tightened after insertion to provide a stable foundation for subsequent assembly.
