DETAILED DESCRIPTION

[0016] The present invention is described in detail below through specific embodiments, but it should be pointed out that the following specific implementation methods do not impose technical limitations on the technical scheme, and those skilled in the art can make further technical extensions under the guidance of the following specific technical scheme.

[0017] Embodiment 1: A multi-hole concentric positioning device includes a platform 1. The platform 1 can be fixed and used for fixed-point operation on the production line inside the frame. In this embodiment, for ease of use, the platform 1 is specially designed as a frame 12, and a moving wheel 11 is fixed at the bottom of the frame 12. The moving wheel 11 can realize the flexible movement of the device, which is more suitable for flexible promotion and use in the workshop.

[0018] A working surface 15 is provided on the top surface of the platform 1, on which a pushing device 3 is provided, and four clamping pliers 18 are evenly distributed around the working surface 15; the working surface 15 is also provided with large-diameter holes 151 corresponding to the products A6 and B8, which are used to fix the products A6 and B8.

[0019] The ejection device 3 includes a round or square tray 31, the bottom of the tray 31 is connected to the vertical drive device below through a push shaft 32, and the vertical drive device can drive the tray 31 in the ejection device 3 to move vertically on the work surface 15; in this field, the vertical drive device is a vertically arranged electric push rod 4 or a cylinder or an oil cylinder. In this embodiment, an electric push rod 4 is selected, and a lower hinge point 41 is arranged at the bottom of the electric push rod 4, and an upper hinge point 43 is arranged at the top of the electric push rod 4. The lower hinge point 41 is hinged and fixed to the support seat 14, and the lower hinge point 43 is hinged to the push shaft 32.

[0020] The support seat 14 is welded or bolted to the support platform 13, and the support platform 13 is arranged below the working surface 15. Generally, the support platform 13 can be understood as a flat plate horizontally welded inside the frame 12, and the support seat 14 is fixed in the middle of the flat plate. Furthermore, the present invention also provides a guide hole 16 in the frame 12, and the push shaft 32 is vertically guided by the guide hole 16 when it moves vertically.

[0021] The purpose of the electric push rod 4 and the ejection device 3 is to achieve vertical lifting, and to push product A and product B out of the working surface 15 synchronously. Therefore, in order to ensure the stability of the vertical push of the electric push rod 4, this embodiment is specially provided with a controller tray 17 on the platform 1, and the controller tray 17 is provided with a controller 5 inside. The controller 5 is provided with a power line 51 connected to the outside to realize power supply, and the controller 5 is also provided with a switch 52 to control whether the switch is on or off, and the display control area 53 is used to adjust and display the supply pressure. The controller 5 is also provided with a connecting line 54 connected to the connecting end on the cylinder body 42 for input and output of power and signals. Under the precise control of the controller 5, the stable vertical pressure supply of the device can be realized, and the vertical lifting of the assembly can be realized.

[0022] In actual application cases, if a liquid or air supply system is set up on site, the electric push rod 4 can be replaced by an oil cylinder or an air cylinder, and the controller 5 can be synchronously replaced by a hydraulic or pneumatic controller. The vertical drive control achieved by leveling the controller and the control oil cylinder or air cylinder has the same function.

[0023] When the present invention is in use, in order to improve the stability of the vertical drive of the ejection device 3, the ejection device 3 can be designed as a single one and set at the center of the working surface 15, or the ejection device 3 can also be multiple and evenly distributed around the center point of the working surface 15. When the ejection device 3 is set as multiple, if only a single electric push rod 4 is set, multiple trays 31 can be synchronously hinged at the top force-applying end of the electric push rod 4 to achieve synchronous rising. Multiple support seats 14 can also be horizontally arranged on the support platform 13, and an electric push rod 4 is arranged on each support seat 14. Multiple electric push rods 4 respectively fix the trays 31 on the force-applying end to achieve multi-point vertical drive. The purpose of the above settings is to keep the ejection device 3 stable when pushing the combined product.

The locking pin 2 includes a butterfly nut 22 and a locking screw 21. The top of the locking screw 21 is provided with a large diameter surface 23, and a concentric shaft 24 is provided on the large diameter surface 23. The bottom of the concentric shaft 24 is provided with a concentric shaft step 27, which can be understood as the concentric shaft 24 being a stepped shaft; the upper part of the concentric shaft 24 is also provided with a radial hole 25, and a fixing key 26 is provided in the radial hole 25. During assembly, the large diameter surface 23 is plugged into the large diameter hole 151, and the concentric shaft 24 is plugged into the holes of different apertures on the product A6 and the product B8, which can not only ensure axial concentricity, but also increase the bottom contact area, improve stability, and be suitable for the assembly of products with different apertures.

The hole diameters of the product A6 and the product B8 are different.

[0026] Step 1: First, insert the locking pin 2 into the large diameter hole 151 and slightly screw it with the butterfly nut 22 without tightening it; Step 2: Place the product A6 on the work surface 15 to ensure that each concentric axis step 27 can be completely placed in its large diameter hole 151; Step 3: Apply a layer of structural adhesive 7 evenly on the upper surface of product A6 and then place product B8 on it. Each concentric shaft step 27 can be completely placed in its hole. In steps 2 and 3, please note that if the product hole cannot be completely placed in the concentric shaft step 24, do not squeeze it hard. Gently move the concentric shaft 24 to make it fully inserted. The purpose of designing the locking pin 2 above is to ensure the concentricity of product A6 and product B8 after assembly. Step 4: The butterfly nut 22 is tightened with the fixing key 26 to fix the concentric shaft 24 and the working surface 15 together, and finally the product is pressed with the clamp 18; Step 5: Start timing, waiting for product A6, product B8, and structural adhesive 7 to combine and reach a fixed time; Step 6: Turn on the switch 52 of the controller 5, and control the electric push rod 4 to push out the bonded product at a constant speed through the push-out device 3 through the display control area 53. During this period, the worker needs to pay attention to any risks and quickly press the emergency stop knob in the display control area 53 on the controller 5; Step 7: The present invention also provides a suction cup 9 above the platform 1, which cooperates with the ejection device 3 to realize the outward movement of the product combination above, and the product combination here is a combination product of product A6 and product B8; further, a plurality of hand-operated notches 152 are provided around the edge of the working surface 15, and the operator can place the product A on the working surface 15 and provide hand-assisted protection when detaching through the hand-operated notches 152; after the above work is completed, the suction cup 9 is used to place the bonded product in a suitable position to allow it to completely solidify.

[0029] 4. The electric push rod 4 cooperates with the suction cup 9, and the automation plus manual assistance ensures the concentricity of the uncured product when it is ejected, which can effectively control the product quality and improve the production efficiency.

[0030] 5. The controller device is designed with multiple sets of knobs and display panels, which can adjust the speed and have an emergency stop function to ensure the safety of the operation. The time and function parameters are displayed on the panel to facilitate workers' operation.
