Description

Technical Field

[0001] This utility model relates to the field of pneumatic mechanical gripper technology, and in particular to a cylinder mechanical gripper with an anti-fall structure. Background Technology

[0002] In the machinery industry, pneumatic grippers are commonly used to grasp products. The clamping force is typically provided by a cylinder, and a suitable mechanical structure is designed based on this to meet the required clamping force. The gripped products must meet stability and reliability requirements to avoid a decrease in clamping force caused by abnormal air supply conditions (air shortage, leakage, etc.). When designing with cylinders as the power source, there is often a lack of protection mechanisms to prevent workpieces from shifting, loosening, or falling due to a decrease in clamping force caused by abnormal air supply (such as air shortage or leakage). When the air supply fluctuates, the product may fall or shift position during movement, affecting normal production and quality, and even causing safety accidents. Summary of the Invention

The lower fixing seat is mounted on the base plate; The upper fixing seat is located on top of the lower fixing seat; The transmission component is located inside the lower fixed seat. The bottom end of the transmission component is connected to the piston rod of the cylinder, and the top end of the transmission component passes through the lower fixed seat and the upper fixed seat. The mechanical gripper has its input end connected to the top of the transmission component. When the transmission component is driven to lift by a cylinder, the mechanical gripper opens; when the transmission component is driven to lower by a cylinder, the mechanical gripper closes. The pressure application module is located inside the lower and upper fixed seats and applies downward pressure to the transmission components.

[0004] Furthermore, the pressure application module includes: The receiving plate is sleeved on the transmission component and is located inside the lower fixed seat; Two receiving components are respectively installed on the top of both sides of the receiving plate; Two springs are provided, with their bottom ends fitted onto two receiving parts respectively. The top ends of the two springs pass through the top of the lower fixed seat and the bottom of the upper fixed seat, and contact the inner wall of the top of the upper fixed seat.

[0005] Furthermore, the receiving plate and the transmission components are integrally formed.

[0006] Furthermore, it also includes: a guide sleeve, which is disposed inside the upper fixed seat and sleeved on the transmission component to guide the movement of the transmission component.

[0007] Furthermore, the lower fixed seat has a limiting protrusion at its top and a limiting edge on its upper fixed seat, and the guide sleeve is restricted between the limiting protrusion and the limiting edge.

[0014] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0015] First, combine Figures 1-4 This invention describes a cylinder mechanical gripper with an anti-fall structure, which is used to ensure that the mechanical gripper 600 has a certain clamping force when the air source is abnormal (air shortage, air leakage, etc.), so as to play an anti-fall role. Its application scenarios are very wide.

[0016] like Figures 1-4 As shown, an embodiment of the present invention provides a cylinder mechanical gripper with an anti-fall structure, comprising a cylinder 100, a base plate 200, a lower fixed seat 300, an upper fixed seat 400, a transmission component 500, a mechanical gripper 600, and a pressure application module.

[0017] Specifically, such as Figures 1-4 As shown, the base plate 200 is mounted on the cylinder 100 and connected to the outside of the top of the cylinder 100, but not connected to the piston rod 101 on the cylinder 100.

[0018] Specifically, such as Figures 1-4 As shown, the lower fixing seat 300 is mounted on the base plate 200. The lower fixing seat 300 is a bottom-opening structure that forms a chamber by cooperating with the base plate 200.

[0019] Specifically, such as Figures 1-4 As shown, the upper fixing seat 400 is located on top of the lower fixing seat.

[0020] Specifically, such as Figures 1-4 As shown, the transmission component 500 is located inside the lower fixed seat 300. The bottom end of the transmission component 500 is connected to the piston rod 101 of the cylinder 100, and the top end of the transmission component 500 passes through the lower fixed seat 300 and the upper fixed seat 400. The transmission component 500 moves up and down under the action of the cylinder 100.

[0021] Specifically, such as Figures 1-4 As shown, the input end of the mechanical gripper 600 is connected to the top end of the transmission component 500. When the transmission component 500 is driven to rise by the cylinder 100, the mechanical gripper 600 opens; when the transmission component 500 is driven to fall by the cylinder 100, the mechanical gripper 600 closes. The mechanical gripper 600 can be any existing mechanical gripper that meets the requirements.

[0022] Specifically, such as Figures 1-4 As shown, the pressure application module is installed within the lower fixed seat 300 and the upper fixed seat 400, applying downward pressure to the transmission component 500. The pressure application module includes: a receiving plate 701, two receiving components 702, and two springs 703. The receiving plate 701 is sleeved on the transmission component 500 and is located within the lower fixed seat 300; the two receiving components 702 are respectively located on the top sides of the receiving plate 701; the bottom ends of the two springs 703 are respectively sleeved on the two receiving components 702, and the top ends of the two springs 703 penetrate the top of the lower fixed seat 300 and the bottom of the upper fixed seat 400, contacting the inner top wall of the upper fixed seat 400. The two springs 703 continuously apply pressure to the receiving plate 701, thereby applying downward pressure to the transmission component 500. When the air source is abnormal (air shortage, air leakage, etc.), the two springs 703 drive the transmission component 500 to descend, ensuring the closure of the mechanical gripper 600.

[0023] Furthermore, such as Figures 1-4 As shown, the receiving plate 701 and the transmission component 500 are integrally formed to improve strength.

[0024] Furthermore, such as Figures 1-4 As shown, a cylinder mechanical gripper with an anti-fall structure according to an embodiment of the present invention further includes: a guide sleeve 801, which is disposed inside the upper fixed seat 400 and sleeved on the transmission component 500 to guide the movement of the transmission component 500 and ensure the stability of the movement of the transmission component 500.

[0025] Furthermore, such as Figures 1-4 As shown, the lower fixed seat 300 has a limiting protrusion 802 on its top, and the upper fixed seat 400 has a limiting edge 803. The guide sleeve 801 is restricted between the limiting protrusion 802 and the limiting edge 803, which facilitates the installation and fixation of the guide sleeve 801.

[0026] It should be noted that, as Figures 1-4 As shown in the attached figure, this is a diagram of two sets of cylinder mechanical grippers combined together, but it is not intended to limit this application. The cylinder mechanical grippers of this application can be used individually or in combination.

[0027] Working principle: After air enters the rodless chamber of cylinder 100, the piston rod 101 of cylinder 100 extends, driving the transmission component 500 to move upward through the guide sleeve 801 fixed in the upper fixed seat 400, driving the mechanical gripper 600 to open, and then using the mechanical gripper 600 to prepare to clamp the product.

[0028] After air enters the rod chamber of cylinder 100, the piston rod 101 of cylinder 100 retracts, driving the transmission component 500 to move downward through the guide sleeve 801 fixed in the upper fixed seat 400, driving the mechanical gripper 600 to close, and the mechanical gripper 600 can clamp the product.

[0029] By introducing air into the rodless chamber of cylinder 100 and repeating the above actions, the mechanical gripper 600 can release the clamped product. This concludes the operation flow of this gripper.

[0030] When the air supply is abnormal (air shortage, air leakage, etc.), the lack of pressure in the rodless chamber of cylinder 100 will cause a decrease in the workpiece clamping force, affecting its use. After adding two springs 703, when the piston rod 101 of cylinder 100 extends, the two springs 703 are compressed. At this time, after the pressure in the rodless chamber disappears or weakens, the two springs 703 spring open, driving the mechanical gripper 600 to maintain the clamping state, thereby protecting the closed state of the overall mechanical gripper 600 and ensuring clamping safety.

[0031] Above, refer to Figures 1-4 A cylinder mechanical gripper with an anti-fall structure according to an embodiment of the present invention is described, which has the following beneficial effects: 1. Ensure that the mechanical gripper 600 has a certain clamping force when the gas source is abnormal (gas interruption, gas leakage, etc.); 2. Ensure the reliability and safety of equipment during production.
