Description

Technical Field

[0001] This application relates to the technical field of automotive part pressing, and specifically to a pressing device for vehicle armrests. Background Art

[0002] Automotive accessories are various units that make up an entire vehicle and a type of product that serves the vehicle. Vehicle armrests are standard components in most vehicles. When assembling vehicle armrests, metal shafts and shaft caps are used. The metal is used to support the rotation or movement of the armrest, and the shaft cap can keep the metal shaft from being exposed. When assembling vehicle armrests, the metal shaft and the shaft cap need to be pressed together to form a pre-assembled component, and then this component is installed in the armrest mounting hole.

[0003] For example, the patent with the application number CN202221853338.8 specifically discloses a pressing device for automotive armrest parts. During the use of this device, a driving mechanism is set to drive a pressing plate to move on a slide rail. The guiding mechanism can keep the product to be pressed stable during movement, and the suction attachment can further stabilize the product to be pressed on the mounting hole of the pressing plate, reducing the probability of the product to be pressed falling; the driving mechanism drives the pressing plate to approach the mounting plate until the metal shaft and the shaft cap are completely pressed, and the pressing degree of the relative positions of each metal shaft and shaft cap is the same, ensuring the quality of the product.

[0004] During the use of the above patent, a magnet is used to fix the parts to be pressed pre-assembled with the metal shaft and the shaft cap to reduce the probability of the parts to be pressed falling. However, the effect of only fixing the parts to be pressed by the magnet in the above solution is poor. The parts to be pressed are prone to fall off due to the vibration generated during the operation of the equipment, and it is inconvenient to fix the parts to be pressed made of non-ferromagnetic materials, such as aluminum, copper, or non-magnetic stainless steel materials, which is prone to certain limitations in use, resulting in a reduction in the stability and application range of processing. Therefore, it is necessary to design a pressing device for vehicle armrests to solve the above problems.

[0026] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the present application provides a pressing device for a vehicle armrest, which is applied to the processing of auto parts, and includes: a machine base 1 and a processing component 2.

For example, when installing the pressed workpiece in the armrest mounting hole, two clamping blocks 3024 can be retained to facilitate clamping the armrest for secondary pressing;

[0027] The clamping mechanism 302 further includes a rotating disk 3022 rotatably connected to the bottom of the positioning plate 3021 through a rotating shaft, four sliders 3023 slidably connected to the top of the positioning plate 3021, a connecting column 3025 fixedly installed at the bottom of the slider 3023 and slidably cooperating with the rotating disk 3022, and a gear 3026 fixedly connected to the bottom of the rotating disk 3022 through a connecting shaft and meshing with the rack 3015. The clamping block 3024 is fixedly installed at the top of the slider 3023. The positioning plate 3021 is fixedly connected to the top of the fixed plate 3011 through a base rod. Four chutes are formed through the top of the positioning plate 3021, and the slider 3023 is slidably clamped in the chute. A plurality of arc-shaped guide grooves are formed on the end face of the rotating disk 3022, and the connecting column 3025 passes through the chute and is slidably connected to the arc-shaped guide groove.

[0028] The linear motion mechanism 301 includes a fixed plate 3011 fixedly installed on the top of the machine base 1 and in a U shape, a lead screw 3012 rotatably connected between the two inner walls of the fixed plate 3011, a guide rod 3013 fixedly installed between the two inner walls of the fixed plate 3011 and on one side of the lead screw 3012, a movable block 3014 threadedly connected to the surface of the lead screw 3012 and slidably cooperating with the guide rod 3013, a rack 3015 fixedly installed on one side surface of the movable block 3014, and a power member provided on one side of the fixed plate 3011. The power member includes a motor 3016 fixedly installed on one side surface of the fixed plate 3011, and the output end of the motor 3016 movably passes through the fixed plate 3011 and is connected to the lead screw 3012.

[0029] As Figure 5 shown, the pressing mechanism 201 includes a mounting frame 2011 fixedly installed on one side of the top of the machine base 1, two limit columns 2012 slidably penetrating through the top of the mounting frame 2011, and a hydraulic cylinder 2013 fixedly installed on the top of the mounting frame 2011. The output end of the hydraulic cylinder 2013 movably passes through the mounting frame 2011.

[0030] The pressing mechanism 202 includes a connecting plate 2021 fixedly installed at the output end of the hydraulic cylinder 2013 and connected to the limit column 2012, a plurality of spring devices 2022 fixedly installed at the bottom of the connecting plate 2021, and a pressing plate 2023 fixedly connected to the bottom end of the spring device 2022.

[0031] Working principle:

[0032] First, the staff initially pre-assembles the metal shaft and the shaft cap together to form a product to be clamped. Then, the product to be clamped is placed into the positioning holes on the positioning plate 3021. Subsequently, the motor 3016 drives the lead screw 3012 to rotate, causing the movable block 3014 to slide along the surface of the guide rod 3013. Thereby, the movable block 3014 drives the rack 3015 to move, causing the rack 3015 to drive the engaged gear 3026 to rotate, thus driving the rotating disk 3022 to rotate and driving the connecting column 3025 to move along the arc-shaped guide groove, enabling the four sliders 3023 to move synchronously. Furthermore, the clamping blocks 3024 are driven to move towards the center of the positioning plate 3021 to contact and fix the product to be clamped, achieving the effect of clamping and fixing the product to be clamped. Conversely, reversing the motor 3016 can release the fixation;

[0033] Secondly, the hydraulic cylinder 2013 drives the connecting plate 2021 to move downward, and synchronously drives the limiting column 2012 to slide, ensuring the movement stability of the connecting plate 2021. Thereby, the pressing plate 2023 moves downward to contact and press the product to be clamped;

[0034] Finally, during the pressing process, when the pressing plate 2023 contacts the product to be clamped, the spring device 2022 can be forced to contract, facilitating the buffering of the downward pressure of the pressing plate 2023 and playing a role in protecting the product to be clamped. After pressing, the hydraulic cylinder 2013 drives the pressing plate 2023 to move upward to reset, and reversing the motor 3016 releases the fixation of the product to be clamped, and then it can be taken out.

[0035] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
