Description

Technical Field

[0001] This utility model belongs to the field of hole-gripping assembly of plate parts, specifically, it relates to a positioning assembly mechanism based on hole-gripping. Background Technology

[0002] With the rapid development of industrial automation in China, many fields that previously required manual assembly have gradually moved towards automated assembly and have made some progress, including the automated assembly of door panels. Door panels are assembled from many thin plastic parts, using numerous holes and pins for positioning. However, due to the plastic properties of door panel parts, their precision is low and they are easily deformed, making automated assembly difficult. To this day, most factories still use manual assembly for door panels.

[0003] Traditional grippers for thin sheet metal parts (such as door panels) are usually designed to be complex and large, or have high product positioning requirements, and have poor product compatibility, for the following reasons: 1. The gripping features of different parts vary, which makes the design of product grippers more complex and the gripper mechanisms of different products different; 2. The only positioning feature on the part is usually the pin hole, so the gripper usually has an independently designed positioning and guiding mechanism and a gripping mechanism; 3. Due to the product's easily deformable nature, the gripper must have a corresponding shaping mechanism.

[0004] Since the assembly features of typical door panel parts generally include pin positioning mechanisms and their dimensions are easily standardized, this utility model, based on a gripping hole design, provides a quick positioning and assembly mechanism that is easily compatible with different parts. Furthermore, its rapid positioning, gripping, and assembly characteristics effectively address the shortcomings of traditional grippers. Therefore, this utility model possesses significant practical and promotional value.

[0005] To address the aforementioned problems, this utility model proposes a rapid positioning and assembly mechanism based on a gripping hole. Utility Model Content

[0006] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a rapid positioning assembly mechanism based on gripping holes.

[0007] The present invention provides a rapid positioning assembly mechanism based on a gripper flange, a press-fit cylinder mounting plate, side reinforcing ribs, a telescopic cylinder mounting plate, a central reinforcing rib, a telescopic cylinder, a transition plate, a telescopic rod, a steel ball support rod, a support rod fixing block, steel balls, a guide rod, a clamping block, a press-fit cylinder, a pressure block connecting plate, and a pressure block. The press-fit cylinder mounting plate is fixed to the bottom surface of the gripper flange, and the telescopic cylinder mounting plate and the press-fit cylinder are respectively fixed to both sides of the press-fit cylinder mounting plate. The side reinforcing ribs connect to the gripper flange. The flange and the two sides of the press-fit cylinder mounting plate are reinforced with a central reinforcing rib. The telescopic cylinder is fixed to the lower surface of the telescopic cylinder mounting plate. The adapter plate is installed on the lower side of the telescopic cylinder push plate. The telescopic rod and clamping block are fixed below the adapter plate. The two sides of the steel ball support rod are fixed to the lower surface of the telescopic cylinder mounting plate by the support rod fixing block. The steel ball is built into the slot of the steel ball support rod. The telescopic rod passes through the inner hole of the steel ball support rod and is supported on the inner side of the steel ball. The pressure block is fixed to the lower side of the press-fit cylinder by the pressure block connecting plate.

[0008] In a preferred embodiment, the gripper mounting flange can be fixed to the end of the robot or the end of the transplanting mechanism.

[0009] In a preferred embodiment: the steel balls are equally spaced at 120° angles and installed in the slots of the steel ball support rod.

[0010] In a preferred embodiment: the telescopic cylinder can drive the telescopic rod to move up and down, so as to control the steel ball to expand and retract to the outside of the steel ball support rod.

[0011] In a preferred embodiment: the clamping block can press the product down from above as the adapter plate moves downward, forming an upper and lower clamping state with the steel ball.

[0012] In a preferred embodiment: the guide rod can extend into the inner hole of the pin of the part to be assembled below, to complete the positioning of the product installation.

[0013] In a preferred embodiment: the pressing cylinder can drive the pressing block to move downward, pressing the product onto the positioning pin of the product below.

[0014] In a preferred embodiment: the side reinforcing ribs are used to enhance the stability of the connection between the gripper mounting flange and the press-fit cylinder mounting plate.

[0015] In a preferred embodiment: the central reinforcing rib is used to reinforce the connection between the press-fit cylinder mounting plate and the telescopic cylinder mounting plate.

[0016] In a preferred embodiment: the steel ball support rod can extend into the hole of the perforated thin plate part, and work with the steel ball to support the part.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention integrates the gripping hole positioning and gripping functions through the cooperation of the steel ball support rod and the telescopic rod, reducing the number of parts. At the same time, based on the characteristic that the hole pin positioning mechanism can be easily standardized in size, it can be compatible with different perforated thin plate parts, eliminating the need to design grippers separately for different products, significantly improving the versatility of the mechanism and reducing equipment replacement and maintenance costs.

[0018] This invention uses steel balls and clamping blocks to form an upper and lower clamping structure, which can reliably clamp easily deformable parts and avoid the deformation of parts during the gripping process from affecting the assembly accuracy. Moreover, it has low requirements for part loading and positioning. The steel ball support rod can complete the initial positioning by inserting it into the hole, without the need for high-precision loading tooling. This reduces the dependence on the positioning of the previous process and improves the stability and fault tolerance of the assembly process.

[0019] This invention utilizes a telescopic cylinder to drive the opening and closing of steel balls, a guide rod for precise positioning, and a pressing cylinder to complete the pressing process in a continuous sequence. This significantly shortens the cycle of gripping, positioning, and assembly, solves the problem of low efficiency in traditional manual assembly, effectively improves the efficiency of automated assembly of thin plate parts, and has good industrial promotion value.

[0022] like Figure 1-4As shown, this utility model discloses a positioning and assembly mechanism based on a gripper hole, including a gripper mounting flange 1, a press-fit cylinder mounting plate 2, side reinforcing ribs 3, a telescopic cylinder mounting plate 4, a central reinforcing rib 5, a telescopic cylinder 6, an adapter plate 7, a telescopic rod 8, a steel ball support rod 9, a support rod fixing block 10, a steel ball 11, a guide rod 12, a clamping block 13, a press-fit cylinder 14, a pressure block connecting plate 15, and a pressure block 16. The gripper mounting flange 1 can be fixed to the end of a robot or the end of a transfer mechanism. The press-fit cylinder mounting plate... 2. Fixed to the bottom surface of the gripper mounting flange 1, the telescopic cylinder mounting plate 4 and the pressing cylinder 14 are respectively fixed to both sides of the pressing cylinder mounting plate 2. The side reinforcing ribs 3 connect the two sides of the gripper mounting flange 1 and the pressing cylinder mounting plate 2, and the side reinforcing ribs 3 are used to enhance the stability of the connection between the gripper mounting flange 1 and the pressing cylinder mounting plate 2. The middle reinforcing rib 5 is fixed to both sides of the pressing cylinder mounting plate 2 and the telescopic cylinder mounting plate 4 to provide reinforcement. The middle reinforcing rib 5 is used to reinforce the connection between the pressing cylinder mounting plate 2 and the telescopic cylinder mounting plate 4. Next, the telescopic cylinder 6 is fixed to the lower surface of the telescopic cylinder mounting plate 4, the adapter plate 7 is installed on the lower side of the push plate of the telescopic cylinder 6, the telescopic rod 8 and the clamping block 13 are fixed below the adapter plate 7, and the steel ball support rod 9 is fixed to the lower surface of the telescopic cylinder mounting plate 4 on both sides by the support rod fixing block 10. The steel balls 11 are evenly distributed at a 120° angle and built into the slots of the steel ball support rod 9. The steel ball support rod 9 can extend into the hole of the perforated thin plate part, and cooperate with the steel balls 11 to support the part. The telescopic rod 8 passes through the inner hole of the steel ball support rod 9 and is supported by the steel ball support rod 9. Inside the ball, the telescopic cylinder 6 can drive the telescopic rod 8 to move up and down to control the steel ball 11 to expand and retract to the outside of the steel ball support rod 9. The guide rod 12 can extend into the inner hole of the pin of the part to be assembled below to complete the positioning of the product installation. The clamping block 13 can press the product from above as the adapter plate 7 moves down, forming an upper and lower clamping state with the steel ball 11. The pressure block 16 is fixed to the lower side of the pressing cylinder 14 through the pressure block connecting plate 15. The pressing cylinder 14 can drive the pressure block 16 to move downward to press the product onto the positioning pin of the product below.

[0023] Working principle When this utility model is in operation, firstly, the gripper mounting flange 1 is fixed to the end of the robot or the end of the transfer mechanism, which drives the entire mechanism to move above the perforated thin plate part. Then the mechanism descends vertically, so that the steel ball support rod 9 extends into the hole of the part, completing the initial gripping hole positioning. Next, the telescopic cylinder 6 moves downward, driving the telescopic rod 8 to move downward synchronously through the adapter plate 7. When the telescopic rod 8 moves downward in the inner hole of the steel ball support rod 9, it pushes the steel balls 11, which are equally divided into the slots of the steel ball support rod 9 at a 120° angle, outward, so that the steel balls 11 form a support below the part. At the same time, the clamping block 13, which is fixed below the adapter plate 7 along with the telescopic rod 8, moves downward and presses the part from above, forming an upper and lower clamping state with the steel balls 11 below, thereby stably gripping the easily deformable part. Afterwards, the robot or transplanting mechanism moves the gripped part above the part to be assembled. At this time, the guide rod 12 extends into the inner hole of the pin of the part to be assembled below, completing the precise positioning before product installation. Finally, the telescopic cylinder 6 moves upward, causing the telescopic rod 8 to move upward. The steel ball 11, having lost the support of the telescopic rod 8, retracts into the inner hole of the steel ball support rod 9, releasing the support for the lower part. At the same time, the pressing cylinder 14 drives the pressing block connecting plate 15 and the pressing block 16 to move downward, pressing the part onto the positioning pin of the part to be assembled below, thus completing the entire assembly process. This process, through a positioning design based on the hole characteristics of the part, reduces the positioning requirements of the loaded product, and through the upper and lower clamping structure, it adapts to the easily deformable characteristics of thin plate parts, effectively improving assembly efficiency.
