[0037] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1:

[0040] See Figure 1 and Figure 2 A semi-automatic turntable riveting machine includes a turntable mechanism 100, a riveting mechanism 200 and a blanking mechanism 300. The turntable mechanism 100 is used to play a circular rotation role and has a transmission effect on the product. The riveting mechanism 200 is used to automatically perform riveting operations on the product. The blanking mechanism 300 is used to automatically unload the riveted products.

[0041] Along the rotation direction of the turntable mechanism 100, there are at least loading stations, riveting stations and unloading stations in sequence. The loading station is used to manually load products. Of course, a loading mechanism capable of automatic loading can also be added to the loading station to realize fully automated riveting operations. The riveting mechanism 200 is located at the riveting station and is used to complete the automated riveting operations of the products at the corresponding riveting station. The unloading mechanism 300 is located at the unloading station and is used to complete the automated unloading operations of the products at the corresponding unloading station.

[0042] It should be noted that what is referred to here is at least divided into loading stations, riveting stations and unloading stations in sequence, that is, in this embodiment, there is no restriction on the number of stations divided in the rotation direction of the turntable mechanism 100, and the required work stations can be added according to actual needs and the rotation rules of the turntable mechanism 100 to meet different riveting operation needs.

[0043] A lower mold module 400 is provided at the position corresponding to each work station on the turntable mechanism 100, and a lower riveting jig 500 for carrying the product is detachably installed on the lower mold module 400. An upper mold module 600 is provided at the lower end of the riveting mechanism 200, and an upper riveting jig 700 is detachably installed on the lower end of the upper mold module 600.

[0044] The lower riveting jig 500 is used to carry the product and position the product so that the product can be stably transmitted to the corresponding different workstations for corresponding operations under the rotation of the turntable mechanism 100. At the same time, it can be understood that the upper riveting jig 700 matches the lower riveting jig 500. The upper riveting jig 700 can cooperate with the lower riveting jig 500 to complete the riveting operation of the product under the riveting force of the riveting mechanism 200.

[0045] Here, the lower rivet jig 500 is detachably installed on the lower mold module 400, and the upper rivet jig 700 is detachably installed on the upper mold module 600. The purpose is to be able to disassemble and replace the lower rivet jig 500 and the upper rivet jig 700 according to different product positioning and riveting requirements, so as to be compatible with riveting of different products, nuts, studs and screws, etc., and has the advantage of strong versatility.

[0046] In order to further improve the efficiency of the riveting operation, multiple products that need to be riveted can be positioned on the lower riveting jig 500 at the same time to complete the riveting operation of multiple products at the same time; or when riveting operations need to be completed at multiple positions on the product, corresponding riveting heads are provided on the upper riveting jig 700 for multiple positions to be riveted.

[0047] In the specific operation process, this embodiment adopts a semi-automatic operation mode, that is, after the turntable is manually loaded at the loading station, the turntable mechanism 100 rotates, so that the product is rotated to the riveting station, and the riveting mechanism 200 at the riveting station performs riveting operations on the product. Then, as the turntable mechanism 100 continues to rotate, the product is rotated to the unloading station, and the unloading mechanism 300 at the unloading station performs unloading operations on the product.

[0048] It can be understood that after each rotation of the turntable mechanism 100, there will be an unloaded lower riveting fixture 500 corresponding to the loading station. Therefore, the operator can continuously load the product, effectively avoiding labor waste. At the same time, due to the rotation operation of the turntable mechanism 100, the riveting mechanism 200 and the unloading mechanism 300 can also perform continuous operation, effectively improving work efficiency.

[0049] The present embodiment provides a semi-automatic turntable riveting machine, which sets a lower die module 400 at a position corresponding to each workstation on the turntable mechanism 100, and a lower riveting jig 500 for carrying the product is detachably installed on the lower die module 400, so that the product can be rotated to different workstations with the turntable mechanism 100 to perform corresponding operations, avoiding the existence of operation waiting time, and at the same time can realize semi-automatic riveting operations, effectively improving production efficiency and operation safety. In addition, an upper die module 600 is set at the lower end of the riveting mechanism 200, and an upper riveting jig 700 is detachably installed at the lower end of the upper die module 600. By disassembling and replacing the lower riveting jig 500 and the upper riveting jig 700, it is compatible with riveting of nuts, studs and screws, etc., and has the advantage of strong versatility.

[0050] Example 2:

[0051] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the riveting machine of the utility model. Figure 3 and Figure 4 .

[0052] In this embodiment, the upper mold module 600 includes an upper mold plate 610 and a first mounting plate 620. The upper mold plate 610 is connected to the lower end of the riveting mechanism 200, and the first mounting plate 620 is connected to the lower end of the upper mold plate 610. The upper mold plate 610 is used to transmit the riveting force of the riveting mechanism 200, and is also used for the installation and fixation of the first mounting plate 620. A plurality of first positioning portions 621 are formed on the first mounting plate 620. The upper riveting fixture 700 is positioned and connected to any first positioning portion 621. The plurality of first positioning portions 621 can be compatible with the positioning and installation requirements of different upper riveting fixtures 700 to adapt to the riveting operation requirements of different products and improve the operation compatibility of the riveting machine.

[0053] For example, multiple first positioning portions 621 are evenly spaced and distributed on the first mounting plate 620. The number of first positioning portions 621 can be eight or ten, etc., and this is not limited in this example. The first positioning portion 621 includes two symmetrically distributed positioning holes. Correspondingly, two connecting holes that are compatible with the two positioning holes of the first positioning portion 621 can be formed on the upper riveting jig 700, so that the two connecting holes on the upper riveting jig 700 are aligned with the two positioning holes of any first positioning portion 621. Bolts and other connecting parts can be passed through the connecting holes and the positioning holes to connect and fix the upper riveting jig 700 and the first mounting plate 620.

[0054] In some embodiments, the lower mold module 400 includes a lower template 410, and a plurality of second positioning portions 411 are formed on the lower template 410. The lower riveting jig 500 is positioned and connected to any second positioning portion 411. The plurality of second positioning portions 411 can be compatible with the positioning and installation requirements of different lower riveting jigs 500 to adapt to the riveting operation requirements of different products and improve the operation compatibility of the riveting machine.

[0055] Similarly, multiple second positioning portions 411 are evenly spaced on the lower template 410. The number of second positioning portions 411 can be eight or ten, etc., which is not limited in this example. The second positioning portion 411 includes two symmetrically distributed positioning holes. Correspondingly, two connecting holes that are compatible with the two positioning holes of the second positioning portion 411 can be formed on the lower riveting jig 500, so that the two connecting holes on the lower riveting jig 500 are aligned with the two positioning holes of any second positioning portion 411. Bolts and other connecting parts can be passed through the connecting holes and the positioning holes to connect and fix the lower riveting jig 500 and the lower template 410.

[0056] In some embodiments, the turntable mechanism 100 includes a rotating disk 110 and a rotating drive module 120, and the driving end of the rotating drive module 120 is connected to the rotating disk 110; the lower template 410 is arranged on the rotating disk 110, and under the driving action of the rotating drive module 120, the lower template 410 is driven by the rotating disk 110 to rotate to different workstations, thereby realizing automatic transmission of the product and semi-automatic riveting operation.

[0057] The rotation drive module 120 can adopt a rotation drive method of a quarter-dividing divider combined with a 750W speed regulating motor and a reducer. Compared with the method of Example 1, the rotating disk 110 is divided into four stations in the rotation direction, namely the loading station, the transition station, the riveting station and the unloading station. Among them, the transition station is the station waiting for operation. Of course, the required operating mechanism can be added at the transition station in combination with different riveting operation requirements.

[0058] Furthermore, the rotating disk 110 is a steel plate rotating disk 110. The rotating disk 110 made of steel plate can better withstand the riveting force and ensure the stability of the riveting operation.

[0059] In some embodiments, a floating mechanism 800 is provided between the lower template 410 and the rotating disk 110. The provision of the floating mechanism 800 enables the riveting force to be transferred to the lower template 410, thereby ensuring the quality of the riveting operation.

[0060] For example, the lower template 410 has a quadrilateral structure and four floating mechanisms 800 are located at the four corners of the lower template 410, providing uniform and stable floating for the lower template 410. Of course, the specific shape of the lower template 410 and the specific number of floating mechanisms 800 are not limited in this example and can be adjusted according to actual needs.

[0061] Specifically, the floating mechanism 800 includes a guide rod 810, a spring 820 and a locking plate 830; one end of the guide rod 810 is fixedly connected to the rotating disk 110, and the other end of the guide rod 810 passes through the spring 820 and the lower template 410 in sequence, and is fixedly connected to the locking plate 830, thereby realizing the floating effect of the floating mechanism 800.

[0062] When the riveting mechanism 200 is performing riveting, after the upper riveting jig 700 presses the lower riveting jig 500, the riveting force is transferred to the lower template 410, and the lower template 410 compresses the spring 820 downward. When the riveting mechanism 200 returns to the initial position, the lower template 410 bounces upward under the elastic force of the spring 820. Here, the spring 820 can play a buffering role in the riveting process, thereby improving the riveting quality.

[0063] Example 3:

[0064] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the riveting machine of the utility model. Figure 5 and Figure 6 .

[0065] In this embodiment, the unloading mechanism 300 includes a first transverse driving module 310, a first lifting driving module 320 and a unloading module 330. The unloading module 330 is connected to the driving end of the first lifting driving module 320, and the first lifting driving module 320 is connected to the driving end of the first transverse driving module 310, thereby realizing automated unloading operations for products.

[0066] The unloading module 330 can move to the set position to pick up and unload materials under the joint driving action of the first transverse driving module 310 and the first lifting driving module 320. For example, it can move to the position of the lower riveting jig 500, pick up the product on the lower riveting jig 500, and then move to the set position to unload the product.

[0067] Furthermore, the blanking module 330 includes a vacuum suction cup, an electromagnet or a clamp. According to different operation requirements, a vacuum suction cup, an electromagnet or a clamp is selected to pick up materials in order to adapt to the blanking requirements of different products and improve the operation compatibility of the riveting machine.

[0068] For example, in this example, the unloading module 330 includes a vacuum suction cup, which generates a vacuum adsorption effect to adsorb the surface of the product to achieve the function of removing the product. When unloading, the vacuum suction cup breaks the vacuum adsorption effect, that is, it is separated from the product.

[0069] In some embodiments, a safety light barrier 900 is further included. The safety light barrier 900 is disposed at the loading station to ensure the safety of the operation.

[0070] This embodiment provides a semi-automatic turntable riveting machine. An operator loads materials at a loading station. To prevent the turntable mechanism 100 from moving and causing harm to the operator while the operator is still loading materials, a safety grating 900 is provided to detect whether the operator's hands have left the loading station. The turntable mechanism 100 starts to rotate only after confirming that the operator's hands have left the loading station.

[0071] The utility model provides a semi-automatic turntable riveting machine, which arranges a lower die module at a position corresponding to each work station on the turntable mechanism, and a lower riveting jig for carrying the product is detachably mounted on the lower die module, so that the product can be rotated to different work stations with the turntable mechanism to perform corresponding operations, avoiding operation waiting time, and at the same time can realize semi-automatic riveting operations, effectively improving production efficiency and operation safety. In addition, an upper die module is provided at the lower end of the riveting mechanism, and an upper riveting jig is detachably mounted at the lower end of the upper die module. By disassembling and replacing the lower riveting jig and the upper riveting jig, it is compatible with riveting of nuts, studs, screws, etc., and has the advantage of strong versatility.
