Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a pneumatic gripper structure. Background Technology

[0002] Conventional clamping structures typically achieve rotational clamping action through the linkage of multiple connecting handles. However, in the food industry, especially in meat processing, due to the presence of a large amount of grease and various impurities, substances often fall between the connecting handles during use, leading to problems. Moreover, the drive assembly is usually located internally, making it difficult to clean by direct washing after substances fall in. Disassembling the machine will cause production to stop, and the more structural components there are, the more laborious the cleaning process becomes. Utility Model Content

[0003] To address the problem that conventional multi-handle clamps are not easily rinsed directly, this invention provides a pneumatic gripper structure.

[0004] The technical solution of this utility model is as follows: A pneumatic gripper structure includes a reference plate and a mounting base whose height spacing is adjusted by a drive component; The reference plate is provided with a rotating shaft at both ends. The mounting base is rotatably connected to the two ends of the side closer to the reference plate. The end of the connecting rotating base away from the mounting base is provided with a limit notch. The width of the limit notch is the same as the diameter of the rotating shaft, and the length is greater than the diameter of the rotating shaft. The rotating shaft is parallel to the rotation axis of the connecting rotating base; The limiting notch is penetrated by a rotating shaft and can be driven to rotate by the rotating shaft; The rotating shaft is always located within the limiting notch; The end of the connecting rotary base away from the mounting base extends toward the reference plate away from the mounting base and is connected to a clamping jaw, and the clamping jaw is located on the side of the reference plate away from the mounting base.

[0005] By changing the distance between the reference plate and the mounting base, the rotation drive of the connecting rotary seat can be achieved within a limited range. With the addition of grippers, the rotation drive of the grippers can be completed within a shorter stroke. Furthermore, the open design of the structure is more suitable for the food industry and facilitates rinsing.

[0006] The specific structure of the aforementioned mounting base is as follows: the mounting base includes a mounting plate arranged parallel to the reference plate, and an extension arm is provided on the side of the mounting plate near the reference plate, and the extension arm is connected to the connecting rotating base.

[0007] To avoid mutual interference between structural components, the reference plate is provided with a clearance notch on the movement path of the extension arm, and the end of the extension arm away from the mounting plate can be set lower than the reference plate.

[0008] The horizontal distance between the two rotating shafts on the reference plate can be adjusted to change the angle at which the fixture is used.

[0009] As a preferred embodiment, the two grippers can switch between vertical and horizontal positions.

[0010] To avoid collisions between the grippers, there is a gap between the two vertical grippers.

[0011] The specific structure of the aforementioned gripper is as follows: the gripper includes a vertical plate fixed to the connecting rotary seat, and the vertical plate is bent on one side facing the center of the two grippers.

[0012] To ensure sufficient clamping angle variation, the maximum height distance between the reference plate and the mounting plate is greater than the length of the extension arm.

[0013] To achieve outward expansion, the distance between the two rotating shafts is greater than the distance between the rotating axes of the two connecting rotary seats.

[0014] To facilitate the replacement of easily worn parts, the rotating shaft includes a insert shaft and a rotating ring rotatably sleeved on its outer side, the rotating ring being configured to cooperate with a limiting notch.

[0015] The structure of the aforementioned driving component is as follows: the driving component is a cylinder and is disposed on the side of the mounting base away from the reference plate, and the output end of the cylinder is connected to the reference plate.

[0016] The beneficial effects of this utility model are as follows: This utility model is a pneumatic gripper structure, which is different from the conventional method of driving the gripping action through multiple connecting handles. This device achieves the driving effect by setting the height distance between the reference plate and the mounting base. Specifically, a rotating shaft is set on the reference plate, and a rotatable connecting rotating seat is set on the mounting base. In use, while driving the reference plate to move relative to the mounting base, the connecting rotating seat can be driven by the rotating shaft in conjunction with the limiting notch of the connecting rotating seat. Then, the gripper can be installed on the connecting rotating seat. There are very few linkage parts, and the limiting notch is open. The reference plate is also provided with an avoidance notch. Therefore, it can be directly rinsed during use. Moreover, the opening and closing state of the gripper is outward expansion. In the fully open state, the structural parts can be basically exposed as a whole, so it can be directly rinsed and is not easy to leave impurities. Attached Figure Description

[0017] The advantages and solutions of this application will become clear to those skilled in the art upon reading the following detailed description of preferred embodiments. The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this invention.

[0018] In the attached diagram: Figure 1 This is a schematic diagram of the structure of this utility model (closed state); Figure 2 This is a schematic diagram of the structure of this utility model (in a semi-open state). Figure 3 This is a schematic diagram of the structure of this utility model (fully open state); Figure 4 for Figure 1 Schematic diagram of cross-section structure; The components represented by the various reference numerals in the diagram are: 1. Base plate; 2. Rotary shaft; 3. Connecting pivot; 31. First rotating shaft; 32. Limiting notch; 4. Gripper; 5. Cylinder; 6. Mounting base; 61. Mounting plate; 62. Extension arm. Detailed Implementation

[0019] Example like Figure 1-3 The pneumatic gripper structure shown includes a reference plate 1 and a mounting base 6, which are driven by a drive component to adjust their height spacing. Both the reference plate 1 and the mounting base 6 are horizontally arranged. The drive component is a cylinder 5, which is located on the side of the mounting base 6 away from the reference plate 1. The output end of the cylinder 5 is connected to the reference plate 1. When the mounting base 6 is fixed, the height spacing between the two can be adjusted simply by adjusting the cylinder 5. Moreover, it is not limited to adjusting the height spacing. If tilting or horizontal operation is required, it can also be adapted to change the linear spacing between the reference plate 1 and the mounting base 6.

[0020] Subsequently, the reference plate 1 is provided with rotating shafts 2 at both ends. The purpose of the rotating shafts 2 is not to be used as rotating shafts, but to drive the connecting rotating seat 3. The mounting base 6 is rotatably connected to the connecting rotating seat 3 at both ends near the reference plate 1, and the connecting rotating seat 3 is provided with a limiting notch 32 at the end away from the mounting base 6. The width of the limiting notch 32 is the same as the diameter of the rotating shaft 2, and the length is greater than the diameter of the rotating shaft 2. With this arrangement, the rotating shaft 2 can be inserted into the limiting notch 32. It should be noted that the rotation axis of the rotating shaft 2 and the connecting rotating seat 3 are parallel to each other. In this way, after the rotating shaft 2 is inserted into the limiting notch 32, its up and down movement can drive the connecting rotating seat 3 to rotate. That is to say, the limiting notch 32 is penetrated by the rotating shaft 2 and can be driven to rotate by the rotating shaft 2. Furthermore, under the control of the extension and retraction drive of the cylinder 5, the cylinder 5 can synchronously drive the rotating shaft 2 connected to it, and then drive the connecting rotating seat 3. The rotating shaft 2 is always located within the limiting notch 32. Since the distance between the rotating shaft 2 and the rotation axis of the connecting rotating seat 3 changes during the up and down movement, the limiting notch 32 needs to be able to accommodate the rotating shaft 2 to move within its limited space, but the range of movement cannot exceed it to avoid the structure from deviating from the preset position. Based on this, the driving of the connecting rotating seat 3 can be realized within the controlled range. Moreover, the notch is designed to facilitate cleaning and will not cause the accumulation of impurities.

[0021] Subsequently, based on the above structure, further, the end of the connecting rotary seat 3 away from the mounting base 6 extends towards the reference plate 1 away from the mounting base 6 and is connected to a clamp 4, and the clamp 4 is located on the side of the reference plate 1 away from the mounting base 6, as shown in the figure. Figure 1-3 As shown, the opening angle of the gripper 4 can be changed simply by altering the extension length of the output end of the cylinder 5. Furthermore, its position is below the reference plate 1. During use, the mounting base 6 can be directly fixed in the corresponding position. Only the reference plate 1, the connecting rotary base 3, and the gripper 4 change their states; the mounting base 6 and the cylinder 5 remain in their original positions, facilitating installation. Generally, the two grippers 4 can switch between vertical and horizontal positions.

[0022] Furthermore, to achieve outward expansion, the distance between the two rotating shafts 2 is greater than the distance between the rotation axes of the two connecting rotating seats 3, such as... Figure 1 As shown, when this arrangement is used, as the distance between the reference plate 1 and the mounting base 6 decreases, the aforementioned grippers 4 can expand outwards until they reach the desired position. Figure 3 As shown in the diagram, the gripper 4 is fully extended, facilitating internal cleaning. Furthermore, in... Figure 1As shown, although the gripper 4 is closed, there is a gap between the base plate 1 and the mounting base 6, which makes cleaning convenient. As can be seen from the above structure, cleaning of different positions can be achieved simply by changing the state of the gripper 4, and there are positions that are easy to clean in each state.

[0023] Furthermore, based on the above structure, the horizontal distance between the two rotating shafts 2 on the reference plate 1 can be adjusted to change the angle of the clamp. After adjustment, the adjustment angle of the limiting jaws 4 will change accordingly, and can be adjusted according to usage requirements.

[0024] The above structure can achieve the following: by changing the distance between the reference plate 1 and the mounting base 6, the rotation drive of the connecting rotating seat 3 can be realized within a limited range. Not only are multiple connecting handles not required, but there is only one rotating connection structure between the connecting rotating seat 3 and the mounting base 6. The rotating shaft 2 is only used to drive the connecting rotating seat 3, so it is not easy for impurities to accumulate. With the addition of the gripper 4, the rotation drive of the gripper 4 can be completed within a short stroke. Moreover, the open design of the structure is more suitable for the food industry and is easy to clean.

[0025] As a preferred embodiment, the specific structure of the mounting base 6 is as follows: the mounting base 6 includes a mounting plate 61 arranged parallel to the reference plate 1. In addition to fixing the cylinder 5, the mounting plate 61 also needs to be provided with connecting holes for fixing to the equipment. Moreover, an extension arm 62 is provided on the side of the mounting plate 61 near the reference plate 1, and the extension arm 62 is connected to the connecting rotating seat 3. The provision of the extension arm 62 facilitates the installation of the connecting rotating seat 3, and the adjustment range of the relative position between the connected rotating seat 3 and the rotating shaft 2 after installation will be larger, thus obtaining a larger rotation range of the gripper 4.

[0026] Furthermore, in the above structure, to avoid mutual interference between structural components, the reference plate 1 is provided with a clearance notch on the moving path of the extension arm 62, and the end of the extension arm 62 away from the mounting plate 61 can be set lower than the reference plate 1. Moreover, to ensure sufficient clamping angle variation, the maximum height distance between the reference plate 1 and the mounting plate 61 is greater than the length of the extension arm 62. With this arrangement, the position of the reference plate 1 can be adjusted over a large area, thereby achieving a wide range of changes in the opening and closing angle of the gripper 4. In addition, to avoid collision of the gripper 4, there is a gap between the two vertical grippers 4.

[0027] In one embodiment, the gripper 4 has the following structure: the gripper 4 includes a vertical plate fixed to the connecting rotary seat 3, and the vertical plate has a bend on one side facing the center of the two grippers 4. In this configuration, a cavity can be formed between the two grippers, facilitating gripping actions.

[0028] Finally, to facilitate the replacement of easily worn parts, the rotating shaft 2 includes a insert shaft and a rotating ring rotatably sleeved on its outer side, the rotating ring being configured to cooperate with the limiting notch 32. Since the rotating shaft 2 needs to drive the connecting rotary seat 3, wear will occur during repeated operations. To facilitate replacement, a sleeve structure can be used for adaptation, and the diameter of the sleeve structure can be easily varied according to requirements, making it more versatile.
