[0022] The present invention will be described in detail below through specific embodiments. However, it should be noted that the specific embodiments described below do not limit the technical solution. Those skilled in the art can make further technical extensions under the guidance of the specific technical solutions described below.

[0023] Example 1: A multi-hole concentric positioning device includes a platform 1, which can be fixed and used for fixed-point operation on the production line inside the vehicle frame. In this example, for ease of use, the platform 1 is designed as a frame 12, and a moving wheel 11 is fixed at the bottom of the frame 12. The moving wheel 11 enables the flexible movement of this device, making it more suitable for flexible pushing and use in the workshop.

[0024] The platform 1 has a working surface 15 on its top surface, and a push-out device 3 is provided on the working surface 15. Four clamping clamps 18 are evenly distributed around the perimeter of the working surface 15. The working surface 15 also has large-diameter holes 151 corresponding to products A6 and B8, which are used to fix products A6 and B8.

[0025] The ejection device 3 includes a circular or square tray 31. The bottom of the tray 31 is connected to a vertical drive device below via a push shaft 32. The vertical drive device can drive the tray 31 in the ejection device 3 to move vertically on the working surface 15. In this field, the vertical drive device is a vertically arranged electric push rod 4, a cylinder, or a hydraulic cylinder. In this embodiment, an electric push rod 4 is selected. The bottom of the electric push rod 4 is provided with a lower hinge point 41, and the top of the electric push rod 4 is provided with an upper hinge point 43. The lower hinge point 41 is hinged and fixed to the support base 14, and the lower hinge point 43 is hinged to the push shaft 32.

[0026] The support base 14 is welded or bolted to the support platform 13, which is located below the working surface 15. Typically, the support platform 13 can be understood as a flat plate horizontally welded inside the frame 12, with the support base 14 fixed to the center of the flat plate. Furthermore, this invention also includes a guide hole 16 within the frame 12, through which the push shaft 32 is vertically guided during its vertical movement.

[0027] The purpose of the aforementioned electric push rod 4 and ejection device 3 is to achieve vertical lifting, simultaneously ejecting product A and product B from the working surface 15. Therefore, to ensure the stability of the electric push rod 4's vertical movement, this embodiment specifically includes a controller tray 17 on the platform 1. The controller tray 17 contains a controller 5, which is connected to an external power supply via a power cord 51. The controller 5 also includes a switch 52 to control its operation, and a display control area 53 for adjusting and displaying the supply pressure. The controller 5 also has a connecting wire 54 that connects to the connection point on the cylinder 42 for power and signal input and output. Under the precise control of the controller 5, stable vertical pressure supply can be achieved, enabling the vertical lifting of the assembled components.

[0028] In practical applications, if a liquid or gas supply system is provided on-site, the electric actuator 4 can be replaced with a hydraulic cylinder or pneumatic cylinder, and the controller 5 can be replaced with a hydraulic or pneumatic controller. The vertical drive control achieved by the controller and the hydraulic or pneumatic cylinder is equivalent to the control of the hydraulic cylinder.

[0029] In use, to improve the stability of the vertical drive of the ejector device 3, the ejector device 3 can be designed as a single device located at the center of the working surface 15, or multiple ejector devices 3 can be evenly distributed around the center point of the working surface 15. When multiple ejector devices 3 are used, if only a single electric push rod 4 is used, multiple trays 31 can be simultaneously hinged to the top force-applying end of the electric push rod 4 to achieve synchronous lifting. Alternatively, multiple support seats 14 can be horizontally arranged on the support platform 13, with an electric push rod 4 installed on each support seat 14. The multiple electric push rods 4 can fix the trays 31 at their respective force-applying ends to achieve multi-point vertical drive. The purpose of the above arrangements is to ensure that the ejector device 3 achieves stable horizontal upward movement when pushing the assembled products.

[0030] This utility model also includes a plurality of locking pins 2 on the working surface 15; the locking pins 2 are used to concentrically lock product A6 and product B8 together. Each locking pin 2 includes a wing nut 22 and a locking screw 21. The top of the locking screw 21 has a large-diameter surface 23, on which a concentric shaft 24 is provided. The bottom of the concentric shaft 24 has a concentric step 27, which can be understood as a stepped shaft. The upper part of the concentric shaft 24 also has a radial hole 25, within which a fixing key 26 is installed. During assembly, the large-diameter surface 23 is inserted into the large-diameter hole 151, and the concentric shaft 24 is inserted into holes of different diameters on product A6 and product B8. This ensures axial concentricity, increases the bottom contact area, improves stability, and is suitable for assembling products with different hole diameters.

[0031] Example 2: When using this utility model, as follows Figure 2 , 3 As shown, the working surface 15 is provided with 6 large-diameter holes 151, and products A6 and B8 are respectively provided with 6 holes, with different hole diameters for products A6 and B8.

[0032] Step 1: First, insert the locking pin 2 into the large diameter hole 151 and slightly tighten it with the wing nut 22 without fully tightening it;

[0033] Step 2: Place product A6 on the working surface 15 to ensure that each concentric shaft step 27 can be fully inserted into its large diameter hole 151;

[0034] Step 3: Apply a layer of structural adhesive 7 evenly to the surface of product A6, then place product B8 on top, ensuring that each concentric shaft step 27 can be fully inserted into its hole; in steps 2 and 3, note that if the product hole cannot be fully inserted into the concentric shaft step 24, do not force it, but gently move the concentric shaft 24 to allow it to fully enter; the purpose of the locking pin 2 is to ensure the concentricity of product A6 and product B8 after assembly.

[0035] Step 4: Tighten the wing nuts 22 with the fixing key 26 to fix the concentric shaft 24 and the working surface 15 together, and finally use the clamping pliers 18 to press the product.

[0036] Step 5: Start timing and wait for product A6, product B8, and structural adhesive 7 to bond and reach the set time;

[0037] Step 6: Turn on the switch 52 of the controller 5, and control the electric push rod 4 through the push-out device 3 to push out the bonded product at a uniform speed through the display control area 53. During this process, the worker needs to pay attention and if any risk is found, he / she can quickly press the emergency stop knob in the display control area 53 of the controller 5.

[0038] Step 7: This utility model also includes a suction cup 9 above the platform 1, which works in conjunction with the ejection device 3 to move the product composition outward. Here, the product composition is a combination of product A6 and product B8. Furthermore, several manipulator notches 152 are provided around the edge of the working surface 15. The operator uses the manipulator notches 152 to place product A on the working surface 15 and to provide hand support and protection when removing it. 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 fully cure.

[0039] This utility model has several key technological innovations compared to existing technologies:

[0040] 1. This equipment is a special positioning device designed based on the structural characteristics and processing technology of the two products.

[0041] 2. The main platform can be designed as either movable or fixed. When designed as movable, the moving wheels can be upgraded to braked moving wheels to give it a braking function. It is equipped with a quick-gripping clamp 18, a locking pin 2, a controller 5, an electric push rod 4, and a suction cup 9, integrating multiple functions into one, which provides convenience for workers while ensuring product quality.

[0042] 3. The locking pin 2 is composed of a locking screw 21, a large diameter surface 23, a concentric shaft 24, a radial hole 25, a fixing key 26, and a concentric shaft step 27. This ensures that multiple holes on the product can be installed on the working surface 15 at the same time without damaging the hole walls, thus ensuring product quality.

[0043] 4. The electric push rod 4 works in conjunction with the suction cup 9, and the combination of automation and manual assistance ensures the concentricity of the product when it is not fully cured, which can effectively control product quality and improve production efficiency.

[0044] 5. The controller device is designed with multiple knobs and display panels, which can adjust the speed and are equipped with an emergency stop function to ensure the safety of the device operation. The panel displays the time and function parameters for easy operation by the workers.
