Description

Technical Field

[0001] This utility model belongs to the field of plastic parts processing tooling, specifically relating to a quick positioning structure and a gate shearing structure with a quick positioning structure. Background Technology

[0002] In the automotive industry, exterior parts such as plastic spoilers and rear wings are mostly injection molded from rigid plastics like PC / ABS. After injection molding and mold opening, a mechanical gripper picks up the plastic part and places it onto a gate shearing fixture. Then, pneumatic shears attached to the gate shearing fixture cut the gate on the plastic part. However, due to limitations in the mechanical gripper's picking accuracy and the vibration of the fixture during operation, the gate's positioning on the shearing fixture is inaccurate. This results in the pneumatic shear head not fitting snugly against the gate's shaped surface, leading to problems such as excessive cutting depth or height during the shearing process, thus failing to meet product quality requirements. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by providing a quick positioning structure and a gate shearing structure with a quick positioning structure. The quick positioning structure can achieve precise and rapid positioning of the pneumatic shears and the gate of the plastic part, avoiding problems such as excessive cutting depth or height during the shearing process, and meeting product quality requirements.

[0004] To achieve the above objectives, this utility model provides a quick positioning structure, including a top post, which is disposed on one side of an upper spring plate. The other side of the upper spring plate is connected to one end of a linear guide post. The other end of the linear guide post passes through a spring, a guide post sleeve, a lower spring plate, and a linear bearing in sequence and is connected to a guide post connecting plate. The guide post sleeve is connected to the lower spring plate by fasteners. The spring is disposed on the linear guide post between the upper spring plate and the guide post sleeve. The linear bearing is connected to the lower spring plate by fasteners.

[0005] As a further optimization, the top column includes a top column head, which is connected to one end of the top column mounting plate by fasteners. The other end of the top column mounting plate is connected to one end of the adapter column by fasteners. The other end of the adapter column is connected to one end of the adapter plate by fasteners. The other end of the adapter plate is connected to one end of the bottom column by fasteners. The other end of the bottom column is connected to the upper plate of the spring.

[0006] A gate shearing structure with a quick positioning structure includes a quick positioning structure as described above, wherein the spring plate of the quick positioning structure is further provided with a gate shearing structure for shearing the gate of the plastic part.

[0007] As a further optimization, the gate shearing structure includes a pneumatic shear head, which is connected to the pneumatic shear body by fasteners. The pneumatic shear body is slidably connected to the cylinder mounting plate by a slide rail cylinder, and the cylinder mounting plate is connected to the spring plate of the quick positioning structure.

[0008] As a further optimization, the pneumatic scissors body is provided with a scissor clamp, which is rotatably connected to the clamp mounting plate by fasteners. The clamp mounting plate is connected to the slide rail cylinder by fasteners, and the slide rail cylinder is connected to the cylinder mounting plate by fasteners.

[0009] As a further optimization, the clamp mounting plate is provided with a first long arc-shaped adjustment hole, through which the scissor clamp can rotate relative to the clamp mounting plate.

[0013] Advantages and beneficial effects of this utility model

[0014] 1. The quick positioning structure in this utility model can achieve precise and rapid positioning of pneumatic shears and plastic part gates. With the help of this structure, problems such as excessive cutting depth or height during gate cutting can be effectively avoided due to poor fit between the pneumatic shear head and the gate shaping surface to be cut, thus meeting the product's quality requirements.

[0015] 2. This utility model cleverly integrates the gate shearing structure onto a quick-positioning structure and optimizes and improves the gate shearing structure. Specifically, a proximity sensor is added to the quick-positioning structure to accurately determine whether the plastic part has descended to the correct position. Only when the plastic part has descended to the correct position will the control system of the shearing fixture operate the slide rail cylinder to move the pneumatic shears forward. Simultaneously, a cylinder sensor is added to the slide rail cylinder to determine whether the cylinder has moved to the correct position. Only when the cylinder has moved to the correct position will the control system of the shearing fixture output an air blowing action, causing the pneumatic shears to close, thereby smoothly cutting off the gate of the plastic part. In this way, the function of automatically trimming the gate of the plastic part is achieved.

[0016] 3. This utility model has multiple first long arc-shaped adjustment holes on the clamp mounting plate relative to the scissor clamp, and a second long arc-shaped adjustment hole on the cylinder mounting plate relative to the slide rail cylinder, thereby ensuring that the pneumatic scissors can be adjusted according to the molding surface of the gate.

[0027] like Figure 1 As shown, a quick positioning structure 1 includes a top post 11, which is disposed on one side of the top of the upper spring plate 12. To save costs and simplify the process, this embodiment sets the top post 11 in segments, including a top post head 111, a top post mounting plate 112, a transition post 113, a transition plate 114, and a bottom post 115. The bottom end of the top post head 111 is connected to one end of the top post mounting plate 112 by screws. The other end of the top post mounting plate 112 is connected to one end of the transition post 113 by screws. The other end of the transition post 113 is connected to one end of the transition plate 114 by screws. The other end of the transition plate 114 is connected to one end of the bottom post 115 by screws. The other end of the bottom post 115 is connected to one side of the upper spring plate 12 by screws. In the middle, the stepped design of the top column 11 reduces the area of ​​the upper spring plate 12 and allows the column 11 to bear force centrally. The bottom of the upper spring plate 12 is connected to one end of a plurality of linear guide columns 13. The other end of the linear guide column 13 passes through the spring 14, guide column sleeve 15, lower spring plate 16 and linear bearing 17 in sequence and is connected to the guide column connecting plate 18. The linear guide column 13 can drive the guide column connecting plate 18 to move up and down relative to the linear bearing 17. The spring 14 is used to prevent the quick positioning structure 1 from sinking excessively. The linear bearing 17 is connected to the lower spring plate 16 by fasteners and is used to limit and guide the linear guide column 13. The guide column connecting plate 18 can prevent the spring 14 from popping out the linear guide column 13 when it extends.

[0028] like Figures 2-5As shown, a gate shearing structure 2 with a rapid positioning structure includes the rapid positioning structure 1 described above. The other side of the top of the spring plate 12 of the rapid positioning structure 1 is provided with a gate shearing structure 2 for shearing the gate of a plastic part. The gate shearing structure 2 includes a pneumatic shear head 21, which is connected to a pneumatic shear body 22 by a pin. A shear clamp 25 is provided on the pneumatic shear body 22, and the shear clamp 25 is connected to a clamp mounting plate 26 by screws. The clamp mounting plate 26 has four first long arc-shaped adjustment holes 261 at a position relative to the shear clamp 25, allowing the shear clamp 25 to rotate relative to the clamp mounting plate 26. The clamp mounting plate 26 is connected to a slide rail cylinder 23 by screws, and the slide rail cylinder 23 is provided with a cylinder sensor. The cylinder sensor is used to detect whether the slide rail cylinder has moved into position, thereby controlling whether the pneumatic shears close to cut the gate. The slide rail cylinder 23 is connected to the cylinder mounting plate 24 by screws. The cylinder mounting plate 24 has a second long arc-shaped adjustment hole 241 at the position of the slide rail cylinder 23. The slide rail cylinder 23 can rotate relative to the cylinder mounting plate 24 through the second long arc-shaped adjustment hole 241. The position of the pneumatic shears can be adjusted through the first long arc-shaped adjustment hole 261 and the second long arc-shaped adjustment hole 241 to ensure that the pneumatic shears are adjusted with the molding surface of the gate. The cylinder mounting plate 24 is connected to the upper spring plate 12 by screws. The lower spring plate 16 is also connected to a proximity sensor 4 through a sensor bracket 3. The proximity sensor 4 is used to detect whether the quick positioning structure has descended into position, thereby controlling whether the slide rail cylinder 23 moves forward.

[0029] Figure 6 This is a schematic diagram showing multiple gate shearing structures 2 with quick positioning structures 1 set on the worktable surface 5. In this embodiment, the quick positioning structure 1 is connected to the worktable surface 5 through the lower spring plate 12, while the linear bearing 17 and the guide post connecting plate 18 located at the bottom of the lower spring plate 16 are located inside the worktable surface 5.

[0030] Working principle

[0031] Working principle of rapid positioning structure

[0032] An external injection molding robot uses a mechanical gripper to move a plastic part with a gate onto a gate shearing fixture. The robot then presses the plastic part downwards along the Z-axis by 1-3mm, causing the edge of the gate to abut against the top column head 111. The impact force of the downward pressure on the top column head 111 causes the gate shearing structure 2 and the quick positioning structure 1 to descend. Specifically, the downward movement of the top column head 11 causes the upper spring plate 12 to move downwards, and the linear guide post 13 below the upper spring plate 12 moves downwards within the linear bearing 17. When the spring 14 on the linear guide post 13 reaches its compression limit, the spring 14 begins to extend, causing the gate shearing structure 1 and the top column head 11 to move upwards. This brings the pneumatic shear head 21 on the gate shearing structure 2 and the top column head 111 on the quick positioning structure 1 into contact with the gate molding surface that needs to be sheared. This solves the problems of excessive depth or height during gate shearing, thus meeting the product's quality requirements.

[0033] Working principle of gate shear structure

[0034] The top column head 111 is driven by the impact force of the plastic part pressing down, causing the gate shearing structure 2 and the quick positioning structure 1 to descend as a whole. When the proximity sensor 4 can receive a signal, it means that the plastic part has not been pressed down to the correct position and the next action cannot be performed. When the proximity sensor 4 does not receive a signal, it means that the plastic part has been pressed down to the correct position. The control system of the shearing fixture controls the slide rail cylinder 23 to extend forward and push the pneumatic scissor head 21 to the gate shearing position. After the slide rail cylinder 23 moves to the correct position, the cylinder sensor outputs a position signal. The control system of the shearing fixture outputs a blowing action to drive the pneumatic scissor head 21 to close and cut off the gate. After the gate is cut off, the control system of the shearing fixture stops outputting the blowing action or performs a reverse blowing action to open the pneumatic scissor head 21. The external injection molding robot takes the plastic part away from the shearing position through the mechanical gripper. The control system of the shearing fixture controls the slide rail cylinder 23 to return to the correct position. The gate shearing structure with the quick positioning structure returns to the correct position under the action of the spring 14. The proximity sensor 4 signal is restored, preparing for the next shearing action.
