[0055] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0056] The adjustment wire of the child seat, also known as the control wire, requires riveting the locking pin for connecting the adjustment mechanism and the steel wire for connecting the movable parts of the child seat during the production process of the adjustment wire. To improve the connection quality between the locking pin and the steel wire, a steel wire head is usually provided at one end of the steel wire, and a mounting hole is provided at one end of the locking pin. The steel wire head is accommodated in the mounting hole, and the two are connected by pressing the mounting hole onto the steel wire head. In the related art, for the connection between the locking pin and the steel wire, the locking pin and the steel wire head are usually manually pressed together by workers. However, the applicant has found that since the locking pin is usually cylindrical and small in size, and since the steel wire has a certain flexibility and a small diameter, it is very difficult to fix the locking pin and the steel wire during the process of riveting the locking pin and the steel wire head, and it is extremely easy to have fixing failure, resulting in damage to the locking pin and the steel wire head, and even causing injury to the workers. In addition, during the process of manually pressing the locking pin and the steel wire head by workers, a sufficiently large extrusion force needs to be applied to the locking pin, which will also cause fixing failure between the locking pin and the steel wire, and will also lead to excessive work intensity of the workers, making the workers extremely prone to fatigue, seriously affecting the physical health of the workers, and seriously affecting the production efficiency and production quality of the adjustment wire at the same time.

[0057] In view of this, please refer to Figures 1 to 8, the present utility model provides a riveting jig 100, which can be used to rivet a first workpiece 200 and a second workpiece 300 (the first workpiece 200 can be either a locking pin or a wire head 210. Exemplarily, if the first workpiece 200 is the wire head 210, then the second workpiece 300 can be a locking pin, and the locking pin has a mounting hole 310 for riveting the wire head 210). Among them, the riveting jig 100 includes a pressing assembly 110 and a driving assembly 120. The pressing assembly 110 includes a first pressing block 111 and a second pressing block 112, which are configured to be arranged opposite to each other along a first direction X. The driving assembly 120 includes a first driving member 121 and a second driving member 122. The first driving member 121 is configured to be able to drive the first pressing block 111 and / or the second pressing block 112 to move along the first direction X, so that the first pressing block 111 and the second pressing block 112 can move towards each other until they abut against each other, thereby facilitating the sleeving of the first workpiece 200 or the second workpiece 300, and further reducing the fixing difficulty of the first workpiece 200 or the second workpiece 300. In some embodiments, the first driving member 121 is configured to be able to drive the first pressing block 111 to move along the first direction X towards the second pressing block 112. In some other embodiments, the first driving member 121 is configured to be able to drive the second pressing block 112 to move along the first direction X towards the first pressing block 111. In still some other embodiments, the first driving member 121 is configured to be able to simultaneously drive the first pressing block 111 and the second pressing block 112 to move along the first direction X towards each other, so that the first pressing block 111 and the second pressing block 112 can abut against each other, and thus the first pressing block 111 and the second pressing block 112 can jointly define a space for fixing the first workpiece 200 or the second workpiece 300, thereby realizing the fixing of the first workpiece 200 or the second workpiece 300. Compared with using a single pressing block to fix the first workpiece 200 or the second workpiece 300 (the pressing block is provided with a through hole, and the first workpiece 200 or the second workpiece 300 is fixed by passing it through the through hole), in the present application, by the combined use of the first pressing block 111 and the second pressing block 112, the fixing difficulty of the first workpiece 200 or the second workpiece 300 is reduced, the fixing process of the first workpiece 200 or the second workpiece 300 is simplified, and the riveting efficiency is improved.

[0058] The second driving member 122 is configured to be able to drive the first pressing block 111 and the second pressing block 112 to move along the second direction Y, where the second direction Y intersects with the first direction X (the relationship between the first direction X and the second direction Y includes but is not limited to being perpendicular). For the convenience of description, the following takes the first pressing block 111 and the second pressing block 112 for fixing the first workpiece 200 as an example. The first driving member 121 acts on the first pressing block 111 and the second pressing block 112, making them move towards each other along the first direction X until they come into contact with each other, thereby fixing the first workpiece 200. The second workpiece 300 is arranged on one side of the first pressing block 111 along the second direction Y. The second driving member 122 acts on the first pressing block 111 and the second pressing block 112, making them move along the second direction Y until the first pressing block 111 and the second pressing block 112 are pressed against the second workpiece 300, thereby completing the riveting of the first workpiece 200 and the second workpiece 300. Compared with the related art where the first workpiece 200 and the second workpiece 300 are manually riveted, the riveting jig 100 of the present application effectively improves the riveting efficiency and quality of the first workpiece 200 and the second workpiece 300 through the combined use of the first driving member 121 and the second driving member 122, and further improves the production efficiency and the yield rate of the product. It can be understood that in some embodiments, the design of the first pressing block 111 and the second pressing block 112 moving towards each other can be implemented in various structural forms, including but not limited to a cam mechanism, a screw mechanism, etc. The first driving member 121 and the second driving member 122 can be electrically, pneumatically or hydraulically driven, and by adjusting the stroke and torque of the first driving member 121 and the second driving member 122, the movement trajectories and speeds of the first pressing block 111 and the second pressing block 112 can be optimized, further improving the riveting quality and efficiency.

[0059] Please refer to Figures 2 to 4, in some embodiments, the riveting fixture 100 further includes a base 130. The base 130 includes a first positioning member 131 and a second positioning member 132. The first positioning member 131 is adapted to position the first workpiece 200, and the second positioning member 132 is adapted to position the second workpiece 300. The direction from the first positioning member 131 to the second positioning member 132 is parallel to the second direction Y. Both the first pressing block 111 and the second pressing block 112 are slidably connected to the base 130, and at least one of the first pressing block 111 and the second pressing block 112 is configured to be able to reciprocally slide along the first direction X relative to the base 130. Both the first pressing block 111 and the second pressing block 112 are configured to be able to reciprocally slide along the second direction Y relative to the base 130. The settings of the first positioning member 131 and the second positioning member 132 can accurately position the first workpiece 200 and the second workpiece 300. Thus, when the first pressing block 111 and the second pressing block 112 move along the second direction Y, the first workpiece 200 can be accurately docked with the second workpiece 300 and then riveted, thereby improving the riveting quality of the first workpiece 200 and the second workpiece 300. The first pressing block 111 and the second pressing block 112 are slidably connected and can move in the first direction X and the second direction Y, ensuring the rapid fixation of the first workpiece 200 while improving the reliability of the fixation of the first workpiece 200. In other words, through the combined use of the first positioning member 131, the second positioning member 132, the first pressing block 111, and the second pressing block 112 in this application, the accurate positioning and stable fixation of the first workpiece 200 and the second workpiece 300 are ensured, and the riveting accuracy and quality are improved. It can be understood that, in some embodiments, the first positioning member 131 and the second positioning member 132 can be custom-designed according to the shapes and sizes of different workpieces to meet specific positioning requirements. The first pressing block 111 and the second pressing block 112 can achieve stable sliding through mechanisms such as linear bearings or slide rails. At the same time, a limiting mechanism can be added to prevent deviation during the sliding process and ensure the accuracy of the movement.

[0060] In some embodiments, the first driving member 121 is configured to be able to drive the first pressing block 111 and the second pressing block 112 to move towards each other simultaneously. Specifically, both the first pressing block 111 and the second pressing block 112 are configured to be able to reciprocally slide relative to the base 130 along the first direction X. The first driving member 121 includes a first driving block 1211 and a second driving block 1212. The first driving block 1211 drives the first pressing block 111 to reciprocally slide along the first direction X, and the second driving block 1212 drives the second pressing block 112 to reciprocally slide along the first direction X. The first driving block 1211 is connected to the first pressing block 111, and the first driving block 1211 is used to drive the first pressing block 111 to move along the first direction X. The second driving block 1212 is connected to the second pressing block 112, and the second driving block 1212 is used to drive the second pressing block 112 to move along the first direction X. Through the coordinated movement of the first driving block 1211 and the second driving block 1212, the first pressing block 111 and the second pressing block 112 move towards each other until they abut against each other, so as to sleave the first workpiece 200 or the second workpiece 300. Through the independent driving of the first driving block 1211 and the second driving block 1212 in the first driving member 121, the opposite movement of the first pressing block 111 and the second pressing block 112 is realized, the fixing process of the first workpiece 200 or the second workpiece 300 is simplified, the fixing difficulty of the first workpiece 200 or the second workpiece 300 is reduced, and the positioning accuracy of the first workpiece 200 or the second workpiece 300 is improved. It can be understood that, in some embodiments, the first driving block 1211 and the second driving block 1212 can use an electric cylinder, a cylinder, etc. as the power source, and are connected to the first pressing block 111 and the second pressing block 112 through a connecting rod or other transmission mechanisms to achieve reciprocal sliding. To ensure the smooth sliding of the first pressing block 111 and the second pressing block 112, a guiding structure such as a guide rail or a guiding column can be provided on the base 130.

[0061] Please refer to Figure 3 and Figure 4, the first driving block 1211 is connected to the second driving block 1212, and the first driving block 1211 and the second driving block 1212 are spaced and arranged opposite to each other along the first direction X, and the first driving block 1211 and the second driving block 1212 are configured to reciprocate along the second direction Y relative to the base 130. The first driving block 1211 is provided with a first inclined wall 12111 at the end close to the first pressing block 111, and when the first driving block 1211 slides along the second direction Y, the first inclined wall 12111 abuts against the end of the first pressing block 111 away from the second pressing block 112 and pushes the first pressing block 111 to slide in a direction close to the second pressing block 112. The second driving block 1212 is provided with a second inclined wall 12121 at the end close to the second pressing block 112, and when the second driving block 1212 slides along the second direction Y, the second inclined wall 12121 abuts against the end of the second pressing block 112 away from the first pressing block 111 and pushes the first pressing block 111 to slide in a direction close to the second pressing block 112. In some embodiments, in order to improve the sliding smoothness between the first pressing block 111 and the first inclined wall 12111 and reduce the wear of the first inclined wall 12111, a first inclined surface is provided on the side of the first pressing block 111 close to the first inclined wall 12111, and the first inclined surface is configured to be able to fit with the first inclined wall 12111. Similarly, a second inclined surface is also provided on the side of the second pressing block 112 close to the second inclined wall 12121, and the second inclined surface is configured to be able to fit with the second inclined wall 12121. Specifically, when the first driving block 1211 and the second driving block 1212 move along the second direction Y, the first inclined wall 12111 and the second inclined wall 12121 respectively abut against the first pressing block 111 and the second pressing block 112, and the first pressing block 111 and the second pressing block 112 are pushed to slide toward each other along the first direction X through the action of the first inclined wall 12111 and the second inclined wall 12121. Since the first driving block 1211 and the second driving block 1212 move synchronously along the second direction Y, it is ensured that the first pressing block 111 and the second pressing block 112 can move synchronously toward each other, thereby ensuring the accuracy of the alignment of the first workpiece 200 and the second workpiece 300. The first inclined wall 12111 provided on the first driving block 1211 and the second inclined wall 12121 provided on the second driving block 1212 can effectively utilize the space, so that the movement of the first driving member 121 along the second direction Y can be converted into the movement of the first pressing block 111 and the second pressing block 112 along the first direction X. In addition, after the first pressure block 111 and the second pressure block 112 abut against each other, they can move along the second direction Y under the action of the second driving member 122. Therefore, the riveting fixture 100 of the present application can save the retention time of each mechanism switching the working state before driving the first workpiece 200 or the second workpiece 300 to move along the second direction Y after fixing it, so that the working time from fixing the first workpiece 200 and the second workpiece 300 to riveting each other is shortened, thereby effectively improving the riveting efficiency of the first workpiece 200 and the second workpiece 300.It can be understood that in some embodiments, the first inclined wall 12111 and the second inclined wall 12121 can adopt inclined surfaces with appropriate inclination angles (the specific inclination angles can be designed according to actual processing conditions) to ensure sufficient contact area and pushing efficiency. To ensure the smooth sliding of the first driving block 1211 and the second driving block 1212, corresponding guiding structures can be provided on the base 130.

[0062] Please refer to Figure 3 and Figure 4 , the second driving member 122 includes a third driving block 1221 and a fourth driving block 1222 connected to each other. Both the third driving block 1221 and the fourth driving block 1222 are configured to be able to reciprocate along the second direction Y relative to the base 130. The third driving block 1221 drives the first pressing block 111 to reciprocate along the second direction Y, and the fourth driving block 1222 drives the second pressing block 112 to reciprocate along the second direction Y. It should be noted that the third driving block 1221 and the fourth driving block 1222 can be configured to be able to drive the first pressing block 111 and the second pressing block 112 to reciprocate along the second direction Y simultaneously. Specifically, the first pressing block 111 and the second pressing block 112 can jointly fix the first workpiece 200. The third driving block 1221 and the fourth driving block 1222 respectively control the first pressing block 111 and the second pressing block 112 to move along the second direction Y towards the direction close to the second workpiece 300, so that the first workpiece 200 is riveted to the second workpiece 300. Then the third driving block 1221 and the fourth driving block 1222 respectively control the first pressing block 111 and the second pressing block 112 to move along the second direction Y towards the direction away from the second workpiece 300. During this process, the first pressing block 111 and the second pressing block 112 gradually move away from each other to facilitate material discharging.

[0063] It can be understood that in some embodiments, the third driving block 1221 and the fourth driving block 1222 can be linked with the first pressing block 111 and the second pressing block 112 through transmission mechanisms such as a rack and pinion, a lead screw and nut, etc. To ensure the smooth sliding of the first pressing block 111 and the second pressing block 112, guiding structures such as guiding rails or guiding columns can be added. The movement of the third driving block 1221 and the fourth driving block 1222 can be driven manually, electrically or by other power sources to adapt to different working environments. Exemplarily, in some embodiments, the third driving block 1221 and the fourth driving block 1222 can be linked with the first pressing block 111 and the second pressing block 112 through a rack and pinion mechanism. For example, a rack can be provided on the third driving block 1221, and a gear matching the rack can be provided on the first pressing block 111. When the third driving block 1221 moves along the second direction Y, the rack drives the gear to rotate, thereby causing the first pressing block 111 to slide along the second direction Y. The fourth driving block 1222 can also adopt a similar structural design. Through the cooperation of the rack and the gear, when the fourth driving block 1222 moves along the second direction Y, the second pressing block 112 slides along the second direction Y accordingly. To ensure the smooth sliding of the first pressing block 111 and the second pressing block 112 along the second direction Y, guiding rails can be provided on the base 130, and guiding wheels or guiding blocks can be provided at the bottoms of the first pressing block 111 and the second pressing block 112 to ensure that they can slide stably on the guiding rails. The driving of the third driving block 1221 and the fourth driving block 1222 can adopt power sources such as an electric cylinder, a cylinder, etc., and the movement control of the first pressing block 111 and the second pressing block 112 can be achieved through a linkage mechanism or a direct connection method. In some application scenarios, to improve the riveting accuracy, a position sensor can be set to monitor the positions of the first pressing block 111 and the second pressing block 112, and the movement of the third driving block 1221 and the fourth driving block 1222 can be adjusted through a feedback control system to ensure that the relative positions between the first pressing block 111 and the second pressing block 112 meet the requirements and reduce the rejection rate of the riveting of the first workpiece 200 and the second workpiece 300.

[0064] Please refer to Figure 2 、 Figure 3 and Figure 4, in some embodiments, the third driving block 1221 and the fourth driving block 1222 are located between the first driving block 1211 and the second driving block 1212. The driving assembly 120 further includes a driving portion 123 and a connecting portion 124. The driving portion 123 is connected to the base 130 and the driving portion 123 includes an output end that can slide relative to the base 130 along the second direction Y. The connecting portion 124 is connected to the output end. The first driving block 1211, the third driving block 1221, the fourth driving block 1222, and the second driving block 1212 are arranged at intervals in sequence along the first direction X and are all connected to the connecting portion 124. When the driving portion 123 slides along the second direction Y, the first driving block 1211, the third driving block 1221, the fourth driving block 1222, and the second driving block 1212 are driven to move along the second direction Y through the connecting portion 124. The first driving block 1211 pushes the first pressing block 111 to slide along the first direction X through the first inclined wall 12111. The second driving block 1212 pushes the second pressing block 112 to slide along the first direction X through the second inclined wall 12121 until the first pressing block 111 and the second pressing block 112 abut against each other and fix the first workpiece 200. As the driving portion 123 continues to move along the second direction Y, the third driving block 1221 and the fourth driving block 1222 jointly drive the first pressing block 111 and the second pressing block 112 to slide along the second direction Y. Through the linkage of the driving portion 123 and the connecting portion 124, the reciprocating sliding of the first pressing block 111 and the second pressing block 112 along the second direction Y is realized, and at the same time, the relative movement of the first pressing block 111 and the second pressing block 112 along the first direction X is ensured, improving the riveting efficiency of the first workpiece 200 and the second workpiece 300. It can be understood that, in some embodiments, the driving portion 123 can be an electric cylinder or a cylinder, and the movement of the third driving block 1221 and the fourth driving block 1222 is realized through the reciprocating movement of the output end. The connecting portion 124 can be a connecting rod or a chain, etc., for transmitting power and ensuring the synchronous movement of each driving block.

[0065] Please refer to Figure 3 and Figure 4, in some embodiments, the pressing assembly 110 further includes a sliding block 113. The sliding block 113 is slidably connected to the base 130 and is configured to reciprocally slide relative to the base 130 along the second direction Y. Both the first pressing block 111 and the second pressing block 112 are connected to the sliding block 113, and both the first pressing block 111 and the second pressing block 112 can reciprocally slide relative to the sliding block 113 along the first direction X. In some embodiments, the sliding block 113 can be connected to the base 130 through structures such as guide rails or guide posts and can freely slide in the second direction Y. The first pressing block 111 and the second pressing block 112 can be connected to the sliding block 113 through a guiding structure and can slide relative to the sliding block 113 in the first direction X. When the sliding block 113 moves along the second direction Y, the first pressing block 111 and the second pressing block 112 move together with the sliding block 113. At the same time, the first pressing block 111 and the second pressing block 112 can slide relative to the sliding block 113 in the first direction X through the first driving member 121. The setting of the sliding block 113 realizes the synchronous movement of the first pressing block 111 and the second pressing block 112 along the second direction Y, improving the riveting efficiency and the riveting quality. Through the relative movement of the first pressing block 111 and the second pressing block 112 relative to the sliding block 113, it is possible to ensure the accurate positioning and riveting of the first workpiece 200 and the second workpiece 300, improving the riveting accuracy.

[0066] It can be understood that, in some embodiments, the sliding connection between the sliding block 113 and the base 130 can be realized by a combination of a guide post and a guide hole. The guide post is installed on the base 130, and the guide hole is opened on the sliding block 113. The guide post passes through the guide hole to enable the sliding block 113 to smoothly slide along the second direction Y. To ensure the smooth sliding of the sliding block 113, a guide track can be provided on the base 130, and a guide wheel matching the guide track is provided at the bottom of the sliding block 113 to reduce the friction force. The first pressing block 111 and the second pressing block 112 can be connected to the sliding block 113 by means of a guide groove and a guide pin. The guide pin is installed on the sliding block 113, and the guide groove is opened on the first pressing block 111 and the second pressing block 112. The guide pin is embedded in the guide groove, allowing the first pressing block 111 and the second pressing block 112 to slide relative to the sliding block 113 in the first direction X. To ensure the smooth sliding of the first pressing block 111 and the second pressing block 112, a guide groove can be provided on the sliding block 113, and guide wheels or guide blocks are provided at the bottoms of the first pressing block 111 and the second pressing block 112 to ensure their smooth sliding in the guide groove. The movement of the first pressing block 111 and the second pressing block 112 can be driven by the first driving member 121. The first driving member 121 can be a power element such as an electric cylinder or a cylinder and is connected to the first pressing block 111 and the second pressing block 112 through a connecting rod or a rack and pinion mechanism to realize the relative movement of the first pressing block 111 and the second pressing block 112.

[0067] In some embodiments, the connection between the sliding block 113 and the base 130 can also be achieved by providing a structure with resilience. Please refer to Figure 4 , the pressing assembly 110 further includes a first elastic member 114. The first elastic member 114 is respectively connected to the base 130 and the sliding block 113. The first elastic member 114 is configured to be able to generate a driving force for driving the sliding block 113 to the initial position. When the sliding block 113 is in the initial position, the first pressing block 111 and the second pressing block 112 are away from the riveting positions of the first workpiece 200 and the second workpiece 300. Both the first pressing block 111 and the second pressing block 112 are configured to be able to reciprocally slide along the first direction X relative to the base 130. The pressing assembly 110 further includes a second elastic member 115 and a third elastic member 116. The second elastic member 115 is respectively connected to the sliding block 113 and the first pressing block 111 to drive the first pressing block 111 away from the second pressing block 112. The third elastic member 116 is respectively connected to the second pressing block 112 and the sliding block 113 to drive the second pressing block 112 away from the first pressing block 111.

[0068] Specifically, the first elastic member 114 generates a driving force. When there is no external force, the first elastic member 114 can drive the sliding block 113 to the initial position. At this time, the first pressing block 111 and the second pressing block 112 are away from the riveting positions of the first workpiece 200 and the second workpiece 300. Through the setting of the first elastic member 114, when there is no external force, the first pressing block 111 and the second pressing block 112 automatically move away from the first workpiece 200 and the second workpiece 300, facilitating the placement and removal of the workpieces. When the driving portion 123 drives the connecting portion 124 to move in the second direction Y away from the second workpiece 300, the second elastic member 115 generates a driving force for driving the first pressing block 111 away from the second pressing block 112, and the third elastic member 116 generates a driving force for driving the second pressing block 112 away from the first pressing block 111. Through the action of the second elastic member 115 and the third elastic member 116, the first pressing block 111 and the second pressing block 112 can be kept at a certain distance, which helps to position the first workpiece 200, reduces the difficulty of placing the first workpiece 200, and facilitates the placement and removal of the first workpiece 200.

[0069] It can be understood that, in some embodiments, the first elastic member 114 may be a spring, one end of which is connected to the base 130 and the other end is connected to the sliding block 113. When the sliding block 113 slides along the second direction Y under an external force (including but not limited to the pressure generated on the sliding block 113 during the second driving member 122 driving the first pressing block 111 and the second pressing block 112 to move along the second direction Y), the first elastic member 114 is compressed or stretched. When the external force disappears, the first elastic member 114 returns to its original state and pulls the sliding block 113 back to the initial position. The second elastic member 115 and the third elastic member 116 may also be in the form of springs and are respectively connected between the sliding block 113 and the first pressing block 111 and the second pressing block 112. When the first pressing block 111 or the second pressing block 112 slides along the first direction X under the push of the first driving member 121, the second elastic member 115 or the third elastic member 116 is compressed. When the first driving member 121 no longer applies force, the restoring forces of the second elastic member 115 and the third elastic member 116 cause the first pressing block 111 and the second pressing block 112 to return to their original positions, facilitating the placement and removal of the first workpiece 200. Specifically, through the design of the first elastic member 114, the second elastic member 115, and the third elastic member 116, the process of placing and removing the first workpiece 200 or the second workpiece 300 is simplified, the work efficiency is improved, and it also helps with the positioning of the first workpiece 200 or the second workpiece 300, reducing the difficulty of placing the first workpiece 200 or the second workpiece 300.

[0070] In some embodiments, the first positioning member 131 includes a magnetic member, and the magnetic member is adapted to magnetically attract the first workpiece 200 to position the first workpiece 200; and / or, the first positioning member 131 is provided with a clamping groove 1311, and the clamping groove 1311 is adapted to clamp the first workpiece 200 to position the first workpiece 200; and / or, the second positioning member 132 includes a positioning groove 1321, and the positioning groove 1321 is adapted to clamp the second workpiece 300. In some embodiments, while the first positioning member 131 is provided with the clamping groove 1311, it also has a magnetic member. The first workpiece 200 can be clamped in the clamping groove 1311, and the magnetic member can provide an adsorption force to the first workpiece 200 to firmly fix it to the first positioning member 131. It should be noted that the shape of the clamping groove 1311 can match the shape of the first workpiece 200, so that the first workpiece 200 can be firmly clamped into the clamping groove 1311 to achieve precise positioning of the first workpiece 200 and improve the riveting accuracy. The shape of the positioning groove 1321 matches the shape of the second workpiece 300, so that the second workpiece 300 is clamped into the positioning groove 1321 to achieve precise positioning of the second workpiece 300. The setting of the magnetic member enables the first workpiece 200 to be quickly positioned through magnetic attraction, simplifies the positioning process of the first workpiece 200, and improves the production efficiency.

[0071] It can be understood that, in some embodiments, the magnetic member includes, but is not limited to, a permanent magnet or an electromagnet. And the first positioning member 131 can be regularly inspected and cleaned, especially the surface cleaning of the magnetic member, to maintain a good magnetic attraction effect, ensure the stability of the first workpiece 200 and the second workpiece 300 during the positioning process, and reduce the poor riveting caused by the shaking of the workpieces.

[0072] Please refer to Figure 7 , in some embodiments, a first recess 1111 is provided on one side of the first pressing block 111 facing the second pressing block 112, and a second recess 1121 is provided on one side of the second pressing block 112 facing the first pressing block 111. When the first pressing block 111 abuts against the second pressing block 112, the first recess 1111 and the second recess 1121 are combined to form a riveting groove, and the riveting groove is adapted for the first workpiece 200 to pass through. Along the second direction Y, the cross-sectional dimension of the riveting groove perpendicular to the second direction Y gradually increases. Specifically, the first pressing block 111 and the second pressing block 112 move towards each other along the first direction X under the drive of the first driving member 121 until they abut against each other. At this time, the first recess 1111 and the second recess 1121 are combined to form a riveting groove, and the portion of the first workpiece 200 for riveting is located in the riveting groove and moves along the second direction Y towards the direction close to the second workpiece 300 together with the first pressing block 111 and the second pressing block 112. Along the second direction Y, the cross-sectional dimension of the riveting groove perpendicular to the second direction Y gradually increases. This design enables the riveting groove to better accommodate the first workpiece 200 during the riveting process of the second pressing block 112 and the first pressing block 111 moving along the second direction Y. After the first workpiece 200 is butted against the second workpiece 300, as the first pressing block 111 and the second pressing block 112 continue to move along the second direction Y, the second workpiece 300 is gradually pressed by the riveting groove and pressed against the first workpiece 200, thereby realizing the riveting of the first workpiece 200 and the second workpiece 300. The design of the first recess 1111 and the second recess 1121 ensures that the first workpiece 200 can pass through smoothly, simplifies the fixing process of the first workpiece 200, and reduces the fixing difficulty of the first workpiece 200.

[0073] It can be understood that in some embodiments, the shapes of the first recess 1111 and the second recess 1121 can be designed as semi-circular, semi-elliptical or other shapes suitable for the shape of the second workpiece 300, so as to ensure that the shape of the riveting groove can adapt to the shape of the second workpiece 300 while being able to press the second workpiece 300. The design of the cross-sectional dimension of the riveting groove gradually increasing in a direction perpendicular to the second direction Y can be achieved by adjusting the depths and shapes of the first recess 1111 and the second recess 1121 to adapt to workpieces of different sizes. In order to ensure the stable abutment between the first pressing block 111 and the second pressing block 112, in some embodiments, a limiting structure can be provided between the first pressing block 111 and the second pressing block 112 to prevent the first workpiece 200 from being damaged due to excessive extrusion.

[0074] The operation process of producing the adjustment line using the riveting jig 100 provided by the present application includes but is not limited to the following:

[0075] First, the first workpiece 200 is clamped in the clamping groove 1311, and the second workpiece 300 is fixed in the positioning groove 1321. During this process, the first pressing block 111 and the second pressing block 112 are in a state of being away from each other, and the first driving member 121 and the second driving member 122 are in a stalled state.

[0076] The riveting jig 100 is started, so that the driving assembly 120 starts to work. The driving portion 123 drives the connecting portion 124 to move in the second direction Y towards the direction close to the second positioning member 132. Then, the first driving block 1211 and the second driving block 1212 of the first driving member 121 move along with the connecting portion 124. During this process, the first pressing block 111 moves in the first direction X towards the direction close to the second pressing block 112 under the push of the first inclined wall 12111, and at the same time, the second pressing block 112 moves in the first direction X towards the direction close to the first pressing block 111 under the push of the second inclined wall 12121 until the first pressing block 111 and the second pressing block 112 abut against each other, and the first recess 1111 and the second recess 1121 are combined to form a riveting groove. At this time, the portion of the first workpiece 200 for riveting is located in the riveting groove. The driving portion 123 continuously drives the connecting portion 124 to move in the second direction Y towards the direction close to the second positioning member 132.

[0077] With the continuous movement of the connecting portion 124, the third driving block 1221 and the fourth driving block 1222 of the second driving member 122 abut against the side of the first pressing block 111 and the second pressing block 112 away from the second workpiece 300, and push the first pressing block 111 and the second pressing block 112 to continuously move towards the direction of the second positioning member 132 until the portion of the second workpiece 300 for riveting the first workpiece 200 is butted and pressed against the first workpiece 200.

[0078] Then, the driving part 123 drives the connecting part 124 to move in the second direction Y away from the second positioning part 132. During this process, the first driving block 1211, the second driving block 1212, the third driving block 1221 and the fourth driving block 1222 move along with the connecting part 124 in the direction away from the second positioning part 132. Thus, the third driving block 1221 and the fourth driving block 1222 gradually disengage from the first pressing block 111 and the second pressing block 112, and the first elastic member 114 gradually recovers from the compressed state to the initial state until the third driving block 1221 and the fourth driving block 1222 completely disengage from the first pressing block 111 and the second pressing block 112. As the connecting part 124 continues to move in the direction away from the second positioning part 132, the first pressing block 111 gradually slides away from the first inclined wall 12111, and at the same time, the second pressing block 112 gradually slides away from the second inclined wall 12121. Thus, the second elastic member 115 and the third elastic member 116 gradually recover from the compressed state to the initial state, so that the first pressing block 111 and the second pressing block 112 are separated from each other. Finally, the riveted adjustment wire is taken out.

[0079] Please refer to Figure 6 and 8 , in some embodiments, in order to ensure that the first driving block 1211 and the second driving block 1212 can provide a stable and effective driving force to the first pressing block 111 and the second pressing block 112, the base 130 is further provided with a relatively arranged first protective member 133 and a second protective member 134. The second positioning member 132 is located between the first protective member 133 and the second protective member 134. One side of the first protective member 133 close to the second positioning member 132 can slidably abut against the first driving block 1211, and one side of the second protective member 134 close to the second positioning member 132 can slidably abut against the second driving block 1212. During the movement of the first driving block 1211, the second driving block 1212, the third driving block 1221 and the fourth driving block 1222 along with the connecting part 124 in the second direction Y, the first driving block 1211 can slide relative to the first protective member 133, and the first protective member 133 always abuts against the first driving block 1211; the second driving block 1212 can slide relative to the second protective member 134, and the second protective member 134 always abuts against the second driving block 1212. The settings of the first protective member 133 and the second protective member 134 can provide a guiding effect on the movement of the first driving block 1211 and the second driving block 1212. At the same time, the first protective member 133 and the second protective member 134 can provide a supporting force to the first driving block 1211 and the second driving block 1212, reducing the excessive warping of the first driving block 1211 and the second driving block 1212 during long-term use due to the action of the first pressing block 111 and the second pressing block 112, resulting in the fixation failure of the first pressing block 111 and the second pressing block 112 to the first workpiece 200.
