Description

Technical Field

[0001] The invention belongs to the technical field of clamping mechanisms, in particular to a clamping mechanism for processing architectural metal products. Background Art

[0002] With the continuous development of the construction industry, the demand for construction metal products is also increasing. Common construction metal products include building hardware manufacturing. In the processing of metal products, clamping them is one of the indispensable processes. For metal products of different shapes, corresponding clamping mechanisms are also required to ensure the stability of the clamping of metal products and improve the quality of metal products processed and produced.

[0003] A patent application with publication number CN114227314B discloses an automated clamping device for metal product processing. The patent has a fixed frame, multiple drive components, multiple clamping components and multiple propulsion components, and the inclined surface of the propulsion column is set to drive the propulsion rod to move inward when the propulsion column rotates, so as to push the transmission arc plate to move inward when the propulsion rod moves inward, thereby moving the clamping rod inward. Since the transmission arc plate has multiple installation positions on the propulsion column, each installation position corresponds to a different inclined surface of the propulsion column, thereby making the speed of the transmission arc plate moving inward different. By making the speed of the transmission arc plate different, the effect of adjusting the clamping force is achieved.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example:

[0023] like Figures 1 to 7 As shown, a clamping mechanism for processing architectural metal products described in an embodiment of the present invention includes a mounting base 1, a through groove 2 is provided on the upper end surface of the mounting base 1, four grooves 3 are provided on both walls of the inner cavity of the through groove 2, and the four grooves 3 are grouped in two and symmetrically arranged with each other, a threaded rod 4 is rotatably connected to the inner cavity of the groove 3, and a connecting block 38 is threadedly connected to the outer surface of the threaded rod 4, two sliders 5 are fixedly connected between the connecting blocks 38, and a support rod 11 is inserted into the inner part of the upper end of each slider 5, a fixing bolt 10 is internally threadedly connected to the lower end of the slider 5, and the fixing bolt 10 is threadedly installed with the support rod 11, a fixing block 6 is fixedly connected to the upper end of the support rod 11, an adapter 13 is provided between the fixing blocks 6, a clamping block 7 is installed on the outside of the adapter 13, a plurality of support tubes 22 are evenly arranged on one end surface of the clamping block 7, a sealing sleeve 23 is slidably connected to the outer side of the support tube 22, and an anti-slip rubber pad is provided at one end of the sealing sleeve 23.

[0024] Specifically, in the prior art, when processing metal products, a corresponding clamping mechanism is usually selected for the metal product to be processed, and the clamping mechanism is installed on a workbench, and then the metal product to be processed is clamped and fixed. However, if other metal products are temporarily replaced for processing, the clamping mechanism cannot stably clamp the temporarily replaced metal product, and replacing the corresponding clamping mechanism requires a lot of time to disassemble and replace the clamping mechanism from the workbench, which is not only cumbersome to operate, but also affects the efficiency of metal product processing; When processing metal products, the present invention drives the threaded rod 4 to rotate and makes the threaded transmission connecting blocks 38 of the threaded rod 4 move closer to each other. At the same time, the connecting blocks 38 drive the slider 5 to move synchronously, and then the slider 5 drives the support rods 11 to move closer to each other. In the process of moving closer to each other, the support rods 11 will drive the fixing blocks 6 to move, and at the same time drive the clamping blocks 7 to move closer to each other. In the process of the clamping blocks 7 moving closer to each other, the operator places the metal product between the clamping blocks 7, and then can use the clamping blocks 7 to drive the support tube 22 to move, and at the same time, the support tube 22 drives the sealing sleeve 23 to move synchronously. One end of the sealing sleeve 23 is provided with an anti-skid rubber pad, and then the sealing sleeve 23 is used to clamp and fix the metal product. In the process of clamping the metal product, the sealing sleeve 23 can slide on the outside of the support tube 22 to adjust according to the different shapes of the metal products, so as to ensure the stability of the clamping of the metal product. When adjusting the processing angle, the clamp block 7 is driven to rotate, and the clamp block 7 is made to rotate outside the adapter 13 using the adapter interface 14. At the same time, the clamp block 7 drives the support tube 22 to rotate, and then drives the sealing sleeve 23 to rotate. During the rotation process, the sealing sleeve 23 uses the anti-slip rubber pad to drive the metal product to rotate and adjust the position that needs to be processed. This solves the problem that when the existing clamping mechanism for processing building metal products is used to process metal products, the corresponding clamping mechanism is usually selected for the metal product to be processed, and the clamping mechanism is installed on the workbench, and then the metal product to be processed is clamped and fixed. However, if other metal products are temporarily replaced for processing, the clamping mechanism cannot stably clamp the temporarily replaced metal product. Replacing the corresponding clamping mechanism requires a lot of time to disassemble and replace the clamping mechanism from the workbench, which is not only cumbersome to operate, but also affects the efficiency of metal product processing.

[0025] like Figure 1 , Figure 4 and Figure 5As shown, a plurality of through holes 40 are evenly opened in the inner cavity of the clamping block 7, and the plurality of through holes 40 are connected to the inner cavity of the support tube 22, a micro spring 24 is fixedly connected to the bottom of the inner cavity of the sealing sleeve 23, and one end of the micro spring 24 is fixedly connected to the support tube 22, an annular rubber sealing ring is arranged on the inner wall of the sealing sleeve 23, and the sealing sleeve 23 slides on the outside of the support tube 22 by means of the annular rubber sealing ring.

[0026] Specifically, when the clamping blocks 7 are driven to move toward each other, the clamping blocks 7 will drive the support tube 22 to move, and the support tube 22 will drive the sealing sleeve 23 to move synchronously, so that the sealing sleeve 23 clamps the metal product. As the clamping blocks 7 continue to move, the sealing sleeve 23 will drive the annular rubber sealing ring to slide outside the support tube 22 and clamp the metal product according to the shape of the metal product, thereby ensuring the stability of the clamping of the metal product. Moreover, when the sealing sleeve 23 slides outside the support tube 22, the sealing sleeve 23 will squeeze the micro spring 24 and compress the air in its inner cavity, thereby sealing the metal product. The air in the inner cavity of the sleeve 23 enters the inner cavity of the clamp block 7 through the supporting tube 22 and the through hole 40, and forms pressure on the air in the inner cavity of the clamp block 7. When the air in the inner cavity of the clamp block 7 reaches a certain pressure, it will push the sealing sleeve 23 to rebound, so that the sealing sleeve 23 can clamp and fix the metal product more stably, thereby solving the problem that the existing clamping mechanism for processing metal products for construction is inconvenient to clamp metal products of different shapes, resulting in only the clamping mechanism being selected for the corresponding metal product to clamp and fix it, resulting in the clamping mechanism being not convenient to use.

[0027] like Figure 3 , Figure 4 and Figure 5 As shown, an exhaust port 39 is opened in the middle of the inner cavity of the clamp block 7, and the inner cavity of the exhaust port 39 is fixedly connected to a fixed conduit 18, and one end of the fixed conduit 18 is internally rotatably connected to a driven bevel gear 17, and the driven bevel gear 17 is meshingly connected to a transmission bevel gear 16, and a knob 15 is fixedly connected to the transmission bevel gear 16, and the knob 15 is rotatably connected to the clamp block 7, and one end face of the clamp block 7 is located in the inner cavity of the exhaust port 39 and is rotatably connected to a nozzle 21, and the nozzle 21 is set to be semicircular, and a plurality of nozzle holes are opened on the outside in a semicircular shape.

[0028] like Figure 4 and Figure 5 As shown, a sealing block 19 is fixedly connected to the inner wall of the driven bevel gear 17 , an exhaust hole 20 is opened at one end of the inner cavity of the fixed conduit 18 , and the sealing block 19 is used to seal the exhaust hole 20 .

[0029] Specifically, after the processing of the metal product is completed, the clamp block 7 is driven to drive the support tube 22 to reset, and the support tube 22 drives the sealing sleeve 23 to reset. After the clamp block 7 is reset, the knob 15 is driven to rotate, and the knob 15 drives the transmission bevel gear 16 to rotate. At the same time, the transmission bevel gear 16 engages with the driven bevel gear 17 to rotate. During the rotation process, the driven bevel gear 17 drives the sealing block 19 to rotate, so that the sealing block 19 opens the exhaust hole 20, so that the air in the inner cavity of the clamp block 7 enters the inner cavity of the fixed conduit 18 through the exhaust hole 20, and the air entering the inner cavity of the fixed conduit 18 will impact the nozzle 2. 1 rotates in the inner cavity of the exhaust port 39, and the air is discharged through the nozzle 21, and then the support tube 22 and the sealing sleeve 23 are blown and cleaned to prevent the waste chips generated by the processing of the metal product from remaining between the support tube 22 and the sealing sleeve 23, thereby affecting the clamping effect of the sealing sleeve 23 on the metal product in the later stage, thereby solving the problem that after the existing clamping mechanism for processing metal products for construction is completed, if the waste chips generated by the processing of the metal product between the clamping mechanism are not cleaned, the waste chips remain between the clamping mechanism for a long time, which will cause the waste chips to jam the clamping mechanism, affecting the clamping of the metal product by the clamping mechanism.

[0030] like Figure 1 , Figure 5 and Figure 7 As shown, an adapter interface 14 is provided on one end face of the clamping block 7, and the adapter interface 14 is rotatably installed with the adapter 13, a gear ring 12 is fixedly connected to the outside of the adapter interface 14, and the gear ring 12 is meshingly connected with the gear 9, a servo motor 8 is installed on the upper end of the fixed block 6, and the output shaft end of the servo motor 8 is fixedly connected to the gear 9.

[0031] Specifically, when it is necessary to adjust the processing position of the metal product, the servo motor 8 is started to drive the gear 9 to rotate, and the gear 9 is engaged with the transmission ring gear 12 to rotate. At the same time, the ring gear 12 drives the adapter 14 to rotate, and then drives the clamping block 7 to rotate, and then the clamping block 7 uses the sealing sleeve 23 to drive the metal product to rotate and adjust the processing position. This solves the problem that when the processing position of the metal product needs to be adjusted, the clamping mechanism for existing building metal product processing is usually loosened, and then the metal product is picked up to adjust the processing position. After the processing position of the metal product is adjusted, the clamping mechanism is driven to clamp and fix the metal product, which is not only cumbersome to operate but also not convenient to use.

[0032] Example:

[0033] like Figures 1 to 7As shown, another embodiment of the present invention is: a clamping auxiliary component is arranged between the support rods 11, and the clamping auxiliary component includes two fixed rods 34 fixedly connected between the support rods 11, and the two fixed rods 34 are slidably connected to the outside with support sleeves 32, and one end of one support sleeve 32 is provided with a docking port 37, and one end of the other support sleeve 32 is provided with a docking block, and the docking block and the docking port 37 are plugged into each other.

[0034] like Figure 1 , Figure 6 and Figure 7 As shown, air inlets 36 are provided between the support sleeves 32 , a one-way valve is provided in the inner cavity of the air inlet 36 , a receiving groove 35 is provided between the fixing rods 34 , a second spring 33 is fixedly connected to the inner wall of the support sleeve 32 , and one end of the second spring 33 is fixedly connected to the inner wall of the receiving groove 35 .

[0035] Specifically, when the clamp block 7 is driven to clamp and fix the metal product, the support rod 11 will drive the fixing rod 34 to move, and at the same time, the fixing rod 34 drives the supporting sleeves 32 to move closer to each other, so that the supporting sleeves 32 are docked with the docking port 37 by the docking block, and then the supporting sleeve 32 squeezes the second spring 33 to slide outside the fixing rod 34. During the sliding process of the supporting sleeve 32 outside the fixing rod 34, the air in the inner cavity of the supporting sleeve 32 is squeezed and discharged into the inner cavity of the clamp block 7, thereby increasing the clamp block 7. The pressure of the air in the inner cavity and the pressure in the inner cavity of the clamp block 7 are used to push the sealing sleeve 23 to clamp and fix the metal product, thereby ensuring the stability of the clamping mechanism in clamping the metal product. When the support rods 11 move away from each other and reset, the second spring 33 will bounce the support sleeve 32 to reset. When the support sleeve 32 resets, it will open the one-way valve in the inner cavity of the air inlet 36 and draw external air into the support sleeve 32, thereby improving the practicability of the clamping mechanism and improving the clamping effect of the clamping mechanism.

[0036] like Figure 6 and Figure 7 As shown, a connecting groove 31 is opened on the inner wall of the storage groove 35, an air guide cavity 26 is opened inside the support rod 11, the connecting groove 31 is connected with the inner cavity of the air guide cavity 26, an air storage cavity 25 is opened inside the fixed block 6, the air storage cavity 25 is connected with the air guide cavity 26, and one end of the air storage cavity 25 cooperates with the adapter 13 to communicate with the inner cavity of the clamping block 7.

[0037] like Figure 6 and Figure 7 As shown, the inner cavity of the air guide cavity 26 is fixedly connected to a fixing frame 27, and the fixing frame 27 is slidably connected to a limiting sliding column 28. One end of the limiting sliding column 28 is fixedly connected to a rubber sealing plug 30, and the upper end of the rubber sealing plug 30 is fixedly connected to a first spring 29, and one end of the first spring 29 is fixedly connected to the fixing frame 27.

[0038] Specifically, when the clamp block 7 is driven to clamp and fix the metal product, the support rod 11 will drive the fixing rod 34 to move, and at the same time, the fixing rod 34 drives the supporting sleeves 32 to move closer to each other, so that the supporting sleeves 32 squeeze the air in the inner cavity and discharge it into the connecting groove 31, and at the same time, the air pushes up the rubber sealing plug 30 to squeeze the first spring 29 to move upward, so that the air enters the inner cavity of the air guide cavity 26 and is discharged into the air storage cavity 25. When the supporting sleeve 32 stops squeezing the air in the inner cavity, the first spring 29 will pop up the rubber sealing plug 30 and The rubber sealing plug 30 drives the limiting slide post 28 to slide inside the fixing frame 27, and then the rubber sealing plug 30 seals the connecting groove 31, so as to prevent the air in the inner cavity of the air guide cavity 26 from flowing back into the connecting groove 31, and entering the air storage cavity 25 can improve the clamping effect of the sealing sleeve 23 on the metal product, and after the processing of the metal product is completed, the air in the inner cavity of the air storage cavity 25 can be used to blow and clean the waste chips in the clamping mechanism, thereby improving the practicability of the clamping mechanism and ensuring the clamping effect and stability of the clamping mechanism.

[0039] like Figure 1 and Figure 2 As shown, driving motors are arranged inside both ends of the mounting base 1, and the output shaft ends of the driving motors are fixedly connected to the threaded rods 4. The upper end surface of the mounting base 1 is provided with mounting holes 41 at the four corners.

[0040] Working principle: when processing metal products, the threaded rod 4 is driven to rotate, and the threaded transmission connecting blocks 38 of the threaded rod 4 are moved close to each other, and the connecting blocks 38 drive the slider 5 to move synchronously, so that the slider 5 drives the support rods 11 to move close to each other, and the support rods 11 will drive the fixing blocks 6 to move during the process of moving close to each other, and drive the clamping blocks 7 to move close to each other, and in the process of the clamping blocks 7 moving close to each other, the operator places the metal product between the clamping blocks 7, and then the clamping blocks 7 can be used to drive the support tube 22 to move, and the support tube 22 drives the sealing sleeve 23 to move synchronously, and an anti-slip rubber pad is provided at one end of the sealing sleeve 23, and then the sealing sleeve 23 is used to clamp and fix the metal product, and the sealing sleeve 23 can slide on the outside of the support tube 22 according to the different shapes of the metal products during the clamping process of the metal products, so as to ensure the stability of the clamping of the metal products; When the processing position of the metal product needs to be adjusted, the servo motor 8 is started to drive the gear 9 to rotate, and the gear 9 is engaged with the transmission ring gear 12 to rotate, and the ring gear 12 drives the transfer interface 14 to rotate, and then drives the clamping block 7 to rotate, and then the clamping block 7 drives the metal product to rotate and adjust the processing position by using the sealing sleeve 23; When the clamp block 7 is driven to clamp and fix the metal product, the support rod 11 will drive the fixing rod 34 to move, and the fixing rod 34 will drive the supporting sleeves 32 to move closer to each other, so that the supporting sleeves 32 squeeze the air in the inner cavity and discharge it into the connecting groove 31. At the same time, the air pushes up the rubber sealing plug 30 to squeeze the first spring 29 to move upward, so that the air enters the inner cavity of the air guide cavity 26 and is discharged into the air storage cavity 25. When the supporting sleeve 32 stops squeezing the air in the inner cavity, the first spring 29 will pop up the rubber sealing plug 30 and make The rubber sealing plug 30 drives the limiting slide post 28 to slide inside the fixing frame 27, and then the rubber sealing plug 30 seals the connecting groove 31, thereby preventing the air in the inner cavity of the air guide cavity 26 from flowing back into the connecting groove 31, and entering the air storage cavity 25, which can improve the clamping effect of the sealing sleeve 23 on the metal product, and after the processing of the metal product is completed, the air in the inner cavity of the air storage cavity 25 can be used to blow and clean the waste chips in the clamping mechanism, thereby improving the practicability of the clamping mechanism and ensuring the clamping effect and stability of the clamping mechanism.
