[0027] Terminology explanation:

[0028] Safety lock rod: refers to a mechanical component used for aluminum alloy doors and windows. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, when installing aluminum alloy doors and windows, workers need to first install the connecting rod 02 in the profile 01, and then install the safety lock rod 03 in the profile 01 and outside the connecting rod 02. The safety lock rod 03 is provided with two rotating cards, namely, rotating card A031 and rotating card B032.

[0029] Bit: refers to the head of a tool, usually used to tighten or loosen screws and nuts. The shape and size of the bit match the head of the screw or nut, and can be different shapes such as slot, cross slot, hexagonal, etc. to accommodate different types of fasteners.

[0030] Nailer: A tool or device used to drive nails or similar fasteners into the target material quickly and accurately. In the process of locking aluminum alloy doors and windows, nailers are used to drive screws into locking rods or accessories to achieve a stable connection.

[0031] Example 1

[0032] In order to solve the technical problems mentioned in the background technology, this embodiment proposes a locking device 1 for an aluminum alloy door and window safety lock rod 03, such as Figure 5 As shown, it includes a sliding frame 13, a positioning assembly 16, a first rotating assembly 17, a second rotating assembly 18 and a nailing assembly 19.

[0033] like Figure 6 As shown, the sliding frame 13 includes a vertical slide 131 and a horizontal plate 135 fixed to the side of the vertical slide 131. The horizontal plate 135 is used to install other components to ensure the relative position stability between the components, and the structure of the horizontal plate 135 and the vertical slide 131 ensures the smooth operation of the entire device.

[0034] The positioning assembly 16 is slidably mounted on the bottom surface of the horizontal plate 135, and a positioning pin 161 is provided at the front end of the positioning assembly 16. Figure 7 As shown, the positioning assembly 16 slides forward and backward through the guide rail. During the sliding process, the positioning pin 161 can be inserted into the rotating card A031 of the safety lock rod 03 to prevent the lock rod from shifting and ensure the accuracy of subsequent operations.

[0035] The first rotating assembly 17 is slidably mounted on the top surface of the horizontal plate 135, and a first batch of heads 171 is disposed at the front end of the first rotating assembly 17 on the same vertical line as the positioning pin 161; the second rotating assembly 18 is slidably mounted on the bottom surface of the horizontal plate 135, and a second batch of heads is disposed at the front end of the second rotating assembly 18 on the same horizontal line as the positioning pin 161. Figure 5 , Figure 8 As shown, the first batch head 171 and the positioning pin 161 are kept on the same vertical line, which is convenient for alignment with the rotating card A031. Through the sliding operation, the first rotating component 17 can be moved to the specified position to realize the insertion and rotation operation of the batch head. The second batch head is on the same horizontal line with the positioning pin 161, ensuring that the second batch head can be inserted into the rotating card B032 and drive it to rotate.

[0036] The nailing assembly 19 is slidably mounted on the vertical slide 131. The nailing assembly 19 includes a nailing machine 194. The nailing axis of the nailing machine 194 is on the same vertical line as the positioning pin 161. Fig. 9 The nailing shaft of the nailing machine 194 and the positioning pin 161 are located on the same vertical line, ensuring that the rotating card A031 is accurately aligned with the screw, and finally completing the fastening of the locking rod.

[0037] The positioning pin 161, the first batch of heads 171, and the nailing machine 194 are located on a vertical line. When the positioning pin 161 is positioned, the rotating card A031 is rotated 90 degrees, and the nailing machine 194 is screwed, the device does not need to move in the horizontal direction, and only needs to be moved down to the corresponding position as a whole. The distance between the positioning pin 161 and the second batch of heads is equal to the distance between the rotating card A031 and the rotating card B032 in the safety lock rod 03. Through the coordinated work of the above components, the locking device 1 can realize the precise positioning, rotation and locking operations of the aluminum alloy door and window safety lock rod 03.

[0038] like Figure 6 As shown, the bottom surface of the horizontal plate 135 is installed with a guide rail for the positioning assembly 16 to slide forward and backward, the top surface of the horizontal plate 135 is installed with a guide rail for the first rotating assembly 17 to slide forward and backward, the front side of the horizontal plate 135 is installed with a front mounting plate 133, and the rear side of the horizontal plate 135 is installed with a rear mounting plate 136.

[0039] The positioning assembly 16 is mounted on the guide rail on the bottom surface of the horizontal plate 135 by sliding, so that the positioning assembly 16 can move forward and backward smoothly. The first rotating assembly 17 is mounted on the guide rail on the top surface of the horizontal plate 135 by sliding, so that it can flexibly adjust its position to meet different operating requirements. The rear mounting plate 136 is used to fix the driving components such as the positioning cylinder 163 and the screwdriver cylinder 173. The above structural design is used to improve the stability and flexibility of the overall device.

[0040] like Figure 7 As shown, the positioning assembly 16 also includes a positioning slide 162 and a positioning cylinder 163. The positioning cylinder 163 is installed on the rear mounting plate 136. The front end of the positioning cylinder 163 is connected to the positioning slide 162. The positioning slide 162 is slidably installed on the guide rail on the bottom surface of the horizontal plate 135. The positioning pin 161 is installed on the front end of the positioning slide 162. A second guide plate 134 is installed on the front mounting plate 133. The front end of the positioning pin 161 passes through the second guide plate 134, and a guide sleeve is installed on the inner hole of the second guide plate 134 to prevent the positioning pin 161 from wearing the inner hole of the second guide plate 134.

[0041] When the positioning cylinder 163 is extended, the slide moves forward, and the positioning pin 161 is inserted into the rotating card A031. The positioning pin 161 realizes the positioning and pressing of the safety lock rod 03 by contacting the rotating card A031, forming an effective constraint on the safety lock rod 03, and providing a reliable prerequisite for the subsequent rotation operation. When the cylinder is retracted, the positioning pin 161 exits the rotating card A031, completing the positioning process.

[0042] like Figure 8 As shown, the first rotating assembly 17 also includes a screwdriver motor 172, a screwdriver cylinder 173 and a screwdriver slide 174. The screwdriver cylinder 173 is mounted on the rear mounting plate 136. The front end of the screwdriver cylinder 173 is connected to the screwdriver slide 174. The screwdriver slide 174 is slidably mounted on the guide rail on the top surface of the horizontal plate 135. The front end of the screwdriver cylinder 173 is installed with a reducer, and the first batch of screwdrivers 171 is installed on the reducer. The first guide plate 132 is installed on the front mounting plate 133. The front end of the first batch of screwdrivers 171 passes through the first guide plate 132, and a guide sleeve is installed on the inner hole of the first guide plate 132 to prevent the first batch of screwdrivers 171 from wearing the inner hole of the first guide plate 132.

[0043] The bit cylinder 173 drives the bit slide 174 to slide through a telescopic action. The bit slide 174 is used to carry the bit motor 172 and the reducer. The bit motor 172 drives the first batch of bits 171 to rotate through the reducer. The design of the reducer can be adjusted according to the torque required for the rotating card. The first batch of bits 171 is installed on the reducer and inserted into the rotating card A031 through rotation and completes the locking.

[0044] The structure of the second rotating assembly 18 is the same as that of the first rotating assembly 17, and the two differ only in position and orientation. The first rotating assembly 17 and the second rotating assembly 18 are used to realize a 90-degree rotation of the rotating card A031 and the rotating card B032, and the card edges of the rotating card A031 and the rotating card B032 are clamped in the C-shaped groove of the profile 01.

[0045] like Fig. 9 As shown, the nailing assembly 19 also includes a nailing motor 191, a nailing guide rail 192 and a nailing seat 193. The vertical slide 131 is provided with a slide groove, the nailing guide rail 192 is slidably installed in the slide groove, the nailing seat 193 is connected to the nailing guide rail 192, the nailing machine 194 is installed on the nailing seat 193, the nailing motor 191 is fixed on the vertical slide 131, and the nailing motor 191 is connected to the nailing seat 193 through a ball screw pair.

[0046] The nailing seat 193 is used to install the nailing machine 194, and is connected to the nailing motor 191 through a ball screw pair. The ball screw pair can accurately control the forward and backward movement of the nailing seat 193 and the nailing machine 194. The nailing machine 194 is an outsourced product, and the corresponding nail type and driving parameters can be selected according to the material of the aluminum alloy door and window to ensure the fastening effect. Through this design, the nailing assembly 19 can accurately complete the nailing operation on the rotating card A031, ensuring the stability of the safety lock rod 03.

[0047] like Figure 5 , Fig.10 As shown, the locking device 1 also includes a fixed frame 11, on which a vertical guide rail and a vertical slide 113 are installed. The vertical slide 131 is slidably installed on the vertical guide rail, and the vertical slide 131 is fixedly connected to the vertical slide 113. The vertical slide 113 is driven to rise and fall by a motor and a ball screw pair.

[0048] The fixed frame 11 is the main bearing frame of the device, on which a vertical guide rail is installed to limit the lifting path of the vertical slide 131 and provide support. The vertical slide 113 is fixedly connected between the vertical slide 131 and the driving assembly, and is driven by a motor and a ball screw pair to achieve lifting movement. Through the above structure, the sliding frame 13 can achieve precise positioning in the vertical direction, providing reliable support for the work of the positioning assembly 16, the first rotating assembly 17, the second rotating assembly 18 and the nailing assembly 19.

[0049] like Figure 5 , Fig.11 As shown, the locking device 1 also includes a supporting assembly 15, and a lower mounting plate 112 is installed on the side of the fixed frame 11. The supporting assembly 15 includes a supporting slide rail 151, a supporting seat 152 and a supporting platform 153. The supporting slide rail 151 is fixed on the lower mounting plate 112, the supporting seat 152 is slidably installed on the supporting slide rail 151, and the supporting platform 153 is installed on the supporting seat 152 for supporting the profile 01.

[0050] The supporting rail 151 is fixed on the lower mounting plate 112 of the fixing frame 11. The supporting rail 151 is arranged in the vertical direction to provide support and guidance for the supporting seat 152. The supporting seat 152 is slidably mounted on the supporting rail 151, and its position can be adjusted according to the size of the profile 01 to ensure that the supporting platform 153 can stably support the profile 01. The supporting platform 153 is mounted on the supporting seat 152, and the height of the supporting platform 153 can be adjusted according to actual needs to meet different processing requirements.

[0051] The design of the supporting assembly 15 can provide additional support during the operation of the profile 01, reduce the deformation of the profile 01 with a long length or poor strength during processing and the shaking caused by external forces, and improve the processing accuracy.

[0052] like Figure 5 , Fig.12 As shown, the locking device 1 also includes a vertical clamping assembly 12, an upper mounting plate 111 is installed on the side of the fixed frame 11, and the vertical clamping assembly 12 includes a swing cylinder 121, a swing seat 122, a vertical clamping seat 123, a swing plate 124, a pressure head 125 and a clamping cylinder 126, the vertical clamping seat 123 is fixedly installed on the upper mounting plate 111, the swing plate 124 is rotatably connected to the vertical clamping seat 123, the vertical clamping seat 123 is installed with a swing seat 122, the swing cylinder 121 is rotatably installed on the swing seat 122, the piston rod of the swing cylinder 121 is connected to one end of the swing plate 124, and the other end of the swing plate 124 is installed with a clamping cylinder 126, and the lower end of the clamping cylinder 126 is installed with a pressure head 125 for clamping the profile 01.

[0053] The vertical clamping seat 123 is fixed on the upper mounting plate 111 and serves as a supporting component of the clamping assembly, having good rigidity and stability. The swing cylinder 121 is installed on the vertical clamping seat 123 through the swing seat 122, and its piston rod is connected to one end of the swing plate 124, which can drive the swing plate 124 to swing around the rotation axis. The action of the swing cylinder 121 can adjust the clamping cylinder 126 to an appropriate position in contact with the profile 01, while avoiding interference when loading and unloading the profile 01. The clamping cylinder 126 is installed at the other end of the swing plate 124, and its lower end is connected to the pressure head 125, which is in direct contact with the profile 01 and is used to apply vertical pressure to the profile 01. The design of the vertical clamping assembly 12 ensures that the profile 01 remains stable during the processing and improves the overall operating accuracy of the device.

[0054] like Figure 5 , Fig.13 As shown, the locking device 1 also includes a horizontal pressing assembly 14, which includes a horizontal pressing seat 141, a horizontal pressing cylinder 142 and a horizontal pressing plate 143. The horizontal pressing seat 141 is installed on the upper mounting plate 111, the horizontal pressing cylinder 142 is installed on the horizontal pressing seat 141, and the horizontal pressing plate 143 is installed on the horizontal pressing cylinder 142 for tightening the safety locking rod 03.

[0055] The horizontal pressing seat 141 is fixedly mounted on the upper mounting plate 111 of the fixing frame 11, and is used to support the horizontal pressing cylinder 142 and provide a fixing point. The horizontal pressing cylinder 142 is mounted on the horizontal pressing seat 141, and its piston rod is directly connected to the horizontal pressing plate 143. The horizontal pressing cylinder 142 can be telescopically driven to move the horizontal pressing plate 143, so that it contacts the safety lock rod 03 and applies pressure. The surface of the horizontal pressing plate 143 can be processed into a curved surface or a flat surface according to the shape of the lock rod, for example, it can be set to a serrated shape.

[0056] When the safety lock rod 03 is installed in the C-shaped groove of the profile 01, the positioning pin 161 moves forward under the action of the positioning cylinder 163, and the head of the positioning pin 161 presses against the inner hexagon of the rotating card A031, accurately positioning the safety lock rod 03, and the horizontal pressure plate 143 presses the safety lock rod 03. This action is maintained until the nailing is completed, that is, the horizontal pressure keeps pressing the safety lock rod 03 to ensure that the safety lock rod 03 remains unchanged in this position. Through the cooperation of the horizontal pressing component 14 and the positioning component 16, the safety lock rod 03 can be fixed throughout the entire locking process, providing reliable support for operations such as rotation and nailing.

[0057] Example 2

[0058] This embodiment proposes a working method of the locking device 1 for the aluminum alloy door and window safety lock rod 03 as described in Embodiment 1, comprising:

[0059] The positioning assembly 16 moves forward, so that the positioning pin 161 abuts against the rotating card A031 of the safety lock rod 03, fixing the position of the safety lock rod 03 on the profile 01.

[0060] The horizontal clamping assembly 14 is actuated, driving the horizontal pressing plate 143 to clamp the safety locking rod 03 .

[0061] The second rotating assembly 18 moves forward to insert the second screwdriver into the inner hexagon of the rotating card B032 of the safety lock rod 03. The second screwdriver drives the rotating card B032 to rotate 90 degrees, so that the edge of the rotating card B032 is clamped in the C-shaped groove of the profile 01.

[0062] The positioning assembly 16 moves backward, causing the positioning pin 161 to withdraw from the rotating card A031.

[0063] The sliding frame 13 moves downward, so that the first batch of heads 171 of the first rotating component 17 is aligned with the rotating card A031, and the first batch of heads 171 moves forward and inserts into the rotating card A031 of the safety lock rod 03. The first batch of heads 171 drives the rotating card A031 to rotate 90 degrees, so that the edge of the rotating card A031 is stuck in the C-shaped groove of the profile 01.

[0064] The first rotating assembly 17 moves backward, causing the first batch of heads 171 to exit from the rotating card A031.

[0065] The sliding frame 13 moves downward to align the nailing assembly 19 with the rotating card A031, and the nailing assembly 19 moves forward to install the screw in the rotating card A031 and pierce the connecting rod 02. At this point, the safety lock rod 03 is assembled.

[0066] Through the above steps, the device can complete the positioning and locking operations of the safety lock rod 03 in an efficient and accurate manner, thereby ensuring its safety and reliability in actual use.

[0067] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
