[0002] With the continuous progress of the manufacturing industry, the accuracy and efficiency of product assembly have become the key to competition, especially in the assembly of handrail components. Due to its structural complexity and high requirements for precision, it is particularly important to ensure the accurate positioning and fixation of components. However, there are some problems with the existing handrail fixing methods, which not only affect product quality, but also may lead to a decrease in production efficiency.

[0003] First, the existing fixing methods cannot ensure that the armrest can be securely placed on the processing table. This may be because the design of the fixing device is not precise enough or the adjustment is not flexible enough, which makes the armrest easy to move or offset during the assembly process. This instability not only affects the assembly accuracy, but also may cause poor fit between components, thereby affecting the overall performance and service life of the product.

[0004] Secondly, the existing fixing methods are prone to damage to the armrest when the contact surface is under force. This may be because the pressure of the fixing device is too large or unevenly distributed, causing stress concentration or deformation of the armrest at the force point. This damage not only affects the appearance quality of the product, but may also affect its structural strength and safety of use. Utility Model Content

DETAILED DESCRIPTION

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The utility model embodiment provides a handrail assembly device, such as Figure 1-4As shown, it includes a workbench 1; an assembly body arranged above the workbench 1; the assembly body includes an assembly groove arranged on the outer side of the workbench 1; a screw rod 201 rotating in the assembly groove; a connecting block 202 is threadedly matched on the screw rod 201, and the connecting block 202 is slidably matched with the assembly groove; a connecting plate 203 arranged above the connecting block 202; an assembly platform 204 rotating on the connecting plate 203; a group of vertical plates 205 symmetrically arranged above the assembly platform 204; a group of first electric push rods 206 are arranged on the opposite sides of the two vertical plates 205; the output end of each group of two adjacent electric push rods is provided with a same fastening plate 207; a group of second hydraulic rods 208 are arranged above the fastening plate 207; the output ends of the two second hydraulic rods 208 are provided with a same lower pressure plate 209.

[0025] It should be noted that since the existing fixing methods cannot ensure that the armrest can be firmly placed on the processing table, the armrest is prone to movement or displacement during the assembly process; the pressure of the fixing device is too large or unevenly distributed, resulting in stress concentration or deformation of the armrest at the force point. The present solution achieves high-precision positioning and fixation of the armrest assembly. The device's screw 201 drive, fastening plate 207 and lower pressure plate 209 structure, as well as humanized designs such as the return spring 3 and rubber pad 4 ensure the stability and safety of the assembly during the assembly process. At the same time, the pressure sensor monitors and displays the pressure data of the assembly process in real time, so that the staff can intuitively understand and adjust the operation, further improving the assembly efficiency and quality.

[0026] Specifically, in this embodiment, the scheme mainly includes a workbench 1 and an assembly body; first, the staff places the handrail assembly to be assembled on the assembly platform 204. According to the type and specification of the handrail, the handrail assembly may need to be pre-processed, such as cutting, punching, etc., to meet the subsequent assembly requirements;

[0027] The screw rod 201 starts to rotate. Due to the sliding fit between the connecting block 202 and the assembly groove, the rotation of the screw rod 201 will drive the connecting block 202 to move horizontally in the assembly groove. This movement further adjusts the position of the assembly platform 204 to ensure that the armrest assembly can be accurately positioned in the working area of ​​the equipment. In order to ensure that the processing surface of the armrest assembly can be adjusted arbitrarily during the assembly process, the assembly platform 204 can be rotated and adjusted to ensure that the armrest assembly always maintains a correct posture during the assembly process.

[0028] Next, the first electric push rod 206 starts to work, pushing the fastening plate 207 to move toward the armrest assembly. When the fastening plate 207 contacts the side of the armrest assembly, the first electric push rod 206 continues to apply pressure to firmly fix the armrest assembly on the assembly platform 204. This step ensures that the armrest assembly will not move during the subsequent assembly process.

[0029] After the side of the armrest assembly is fastened, the second hydraulic rod 208 starts to work, and its output end pushes the lower pressure plate 209 to move downward, further pressing the edge of the upper surface of the armrest assembly. In this way, the armrest assembly is completely fixed on the workbench 1, ensuring its stability and accuracy during the assembly process.

[0030] In a further preferred embodiment of the present invention, Figure 3 As shown, a plurality of return springs 3 are disposed on the bottom sides of the lower pressure plate 209 and the fastening plate 207 , a damper is disposed inside the plurality of return springs 3 , and a rubber pad 4 is disposed on the side of the plurality of return springs 3 away from the lower pressure plate 209 .

[0031] In this embodiment, the return spring 3 can not only provide necessary buffering when the lower pressure plate 209 and the fastening plate 207 apply pressure, but also help them quickly return to their original positions after the pressure is released. In order to further control the compression and release speed of the return spring 3, thereby avoiding the adverse effects of too fast or too slow speed on the armrest assembly, dampers are provided in these return springs 3. The dampers can effectively control the vibration and speed of the springs, ensuring that the lower pressure plate 209 and the fastening plate 207 move smoothly and evenly when applying and releasing pressure.

[0032] In addition, in order to ensure that the surface of the armrest assembly will not be scratched or crushed by the lower pressure plate 209 and the fastening plate 207, a rubber pad 4 is arranged on the side of the return spring 3 away from the lower pressure plate 209. The rubber pad 4 has good elasticity and wear resistance, and can effectively protect the surface of the armrest assembly. At the same time, it can also increase the friction between the lower pressure plate 209 and the fastening plate 207 and the armrest assembly, so that it can be more firmly fixed on the assembly platform 204.

[0033] In a further preferred embodiment of the present invention, Figure 4 As shown, a rotary cylinder 5 is disposed in the connection plate 203 , and an output end of the rotary cylinder 5 is fixedly connected to an end key of the assembly platform 204 via a conveyor belt 6 .

[0034] In this embodiment, the rotation of the rotary cylinder 5 is transmitted to the end of the assembly platform 204 through the conveyor belt 6, thereby driving the entire assembly platform 204 to rotate; so that the workpiece can be arbitrarily adjusted during the subsequent assembly process, thereby improving the processing efficiency.

[0035] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a pressure sensor is disposed in the assembly platform 204 , and a display screen 7 is disposed beside the workbench 1 , and the display screen 7 is electrically connected to the pressure sensor.

[0036] In this embodiment, the pressure sensor is placed inside the assembly platform 204, and can monitor the pressure of the handrail assembly during the assembly process in real time. This monitoring is essential to ensure the assembly quality and avoid damage caused by excessive or insufficient pressure; through electrical connection, the pressure sensor transmits the real-time monitored pressure data to the display screen 7; in this way, the staff can intuitively see the current pressure value applied to the handrail assembly during the assembly process; the real-time data feedback on the display screen 7 enables the staff to adjust the assembly process as needed; for example, if the pressure is found to be too high or too low, the staff can adjust the output of the first electric push rod 206 or the second hydraulic rod 208 in time to ensure that the pressure is in the optimal range.

[0037] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a support frame 8 is provided on the upper surface of the workbench 1 away from the screw rod 201 , and a lighting lamp 9 is provided on the bottom side of the support frame 8 .

[0038] In this embodiment, in a dim or insufficiently lit working environment, the lighting lamp 9 can provide sufficient light for the workers to help them clearly see each part of the handrail assembly, thereby ensuring the accuracy and quality of assembly.

[0039] In a further preferred embodiment of the present invention, Figure 1 As shown, the assembly platform 204 is provided with a limiting sliding groove 10 for the sliding of the fastening plate 207 .

[0040] In this embodiment, during the assembly process, the fastening plate 207 needs to withstand a certain pressure or gravity. The design of the limiting slide groove 10 can effectively prevent the fastening plate 207 from tilting or overturning when subjected to force, thereby ensuring the stability and safety of the assembly process.

[0041] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a first motor 11 is disposed on the outer side of the workbench 1 , and an output end of the first motor 11 is fixedly connected to an end key of the screw rod 201 .

[0042] In this embodiment, the first motor 11 serves as a power source and transmits power to the screw rod 201 through a key fixed connection. In this way, when the first motor 11 is started, the screw rod 201 will rotate accordingly, thereby driving the connecting block 202 to move axially along the screw rod 201.

[0043] Working principle: First, the staff places the handrail assembly to be assembled on the assembly platform 204. Depending on the type and specification of the handrail, the handrail assembly may need to be pre-processed, such as cutting, punching, etc., to meet the subsequent assembly requirements;

[0044] When the first motor 11 is started, the screw rod 201 will rotate accordingly, thereby driving the connecting block 202 to move axially along the screw rod 201. Due to the sliding fit between the connecting block 202 and the assembly groove, the rotation of the screw rod 201 will drive the connecting block 202 to move horizontally in the assembly groove. This movement further adjusts the position of the assembly platform 204 to ensure that the armrest assembly can be accurately positioned in the working area of ​​the equipment; in order to ensure that the processing surface of the armrest assembly can be adjusted arbitrarily during the assembly process, the assembly platform 204 can be rotated and adjusted to ensure that the armrest assembly always maintains a correct posture during the assembly process;

[0045] Next, the first electric push rod 206 starts to work, pushing the fastening plate 207 to move toward the armrest assembly. When the fastening plate 207 contacts the side of the armrest assembly, the first electric push rod 206 continues to apply pressure to firmly fix the armrest assembly on the assembly platform 204. This step ensures that the armrest assembly will not move during the subsequent assembly process.

[0046] After the side of the handrail assembly is fastened, the second hydraulic rod 208 starts to work, and its output end pushes the lower pressing plate 209 to move downward, further pressing the edge of the upper surface of the handrail assembly, so that the handrail assembly is completely fixed on the workbench 1, ensuring its stability and accuracy during the assembly process;

[0047] The return spring 3 can not only provide necessary buffering when the lower pressure plate 209 and the fastening plate 207 apply pressure, but also help them quickly return to their original positions after the pressure is released. In order to further control the compression and release speed of the return spring 3, thereby avoiding the adverse effects of too fast or too slow speed on the armrest assembly, dampers are provided in these return springs 3. The dampers can effectively control the vibration and speed of the springs, ensuring that the lower pressure plate 209 and the fastening plate 207 move smoothly and evenly when applying and releasing pressure.

[0048] In addition, in order to ensure that the surface of the armrest assembly will not be scratched or crushed by the lower pressing plate 209 and the fastening plate 207, a rubber pad 4 is provided on the side of the return spring 3 away from the lower pressing plate 209. The rubber pad 4 has good elasticity and wear resistance, and can effectively protect the surface of the armrest assembly. At the same time, it can also increase the friction between the lower pressing plate 209 and the fastening plate 207 and the armrest assembly, so that it is more firmly fixed on the assembly platform 204.

[0049] The pressure sensor (MPS20N0040D-D) is placed inside the assembly platform 204 and can monitor in real time the pressure exerted on the armrest assembly during the assembly process. This monitoring is essential for ensuring assembly quality and avoiding damage caused by excessive or insufficient pressure. Through electrical connection, the pressure sensor transmits the real-time monitored pressure data to the display screen 7. In this way, the staff can intuitively see the current pressure value applied to the armrest assembly during the assembly process. The real-time data feedback on the display screen 7 enables the staff to adjust the assembly process as needed. For example, if the pressure is found to be too high or too low, the staff can promptly adjust the output of the first electric push rod 206 or the second hydraulic rod 208 to ensure that the pressure is within the optimal range.
