Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, and in particular to a handheld suction cup. Background Technology

[0002] In the industrial production and assembly process, various workpieces need to be transferred. During the transfer, clamping equipment is needed to clamp and pick up the workpieces so that they can be stably moved to the designated position for assembly.

[0003] Currently, workpieces are generally clamped using pneumatic grippers or magnetic chucks. Pneumatic grippers mostly clamp from the side and often require connection to an air circuit, making them inconvenient to use and unsuitable for workpieces that require press fitting or are difficult to clamp from the side. Magnetic chucks are also unsuitable for non-ferromagnetic materials or workpieces that are prohibited from being magnetic. Therefore, it is necessary to design a device for the stable adsorption and handling of small workpieces to ensure the transfer and assembly of small workpieces. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as difficulty in clamping workpieces that are inconvenient to clamp from the side and difficulty in clamping workpieces due to the inapplicability of magnetic adsorption. Therefore, a handheld suction cup is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A handheld suction cup includes a handle, a hand control valve is installed at the upper end of the handle, and a suction cup is connected to the lower end of the handle;

[0007] The grip has an air duct through the inside, and the two ends of the air duct are respectively connected to the hand control valve and the suction cup.

[0008] The manual control valve includes a valve body, a through hole at the lower end of the valve body that is connected to the air guide hole, and a pressure relief hole on one side of the valve body that is connected to the through hole. A piston rod matching the through hole is slidably provided in the valve body and a corresponding return spring is provided. The side of the piston rod can close the pressure relief hole.

[0009] Preferably, the piston rod extends out of the upper end of the valve body and is provided with a pressing end.

[0010] Preferably, the upper end of the air guide hole is provided with a mounting hole for installing the valve body, and the valve body is threadedly and sealed in the mounting hole.

[0011] Preferably, the lower end of the grip has a connecting end corresponding to the suction cup, and the suction cup is fitted onto the connecting end.

[0012] Preferably, the sidewall of the grip is covered with an anti-slip pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the suction state of the suction cup is controlled by a manual valve, which facilitates the picking up and releasing of the workpiece. The stability of picking up and transferring the workpiece is improved by increasing and maintaining the negative pressure in the suction cup.

[0015] In this invention, when using a handheld suction cup, the handle is held and the hand control valve is controlled by pressing the end, thereby controlling the suction state of the suction cup. It does not require connection to an air supply device, making it convenient to use. The grip is ergonomic and easy for operators to use.

[0016] In this invention, the suction cup uses a replaceable design, which facilitates replacement after wear and tear, and also makes it easy to change the suction cup model for different types of workpieces, ensuring good adsorption and picking effect for different types of workpieces and improving the compatibility of the handheld suction cup.

[0017] This utility model features a novel design and simple structure, enabling stable picking and transferring of workpieces. It also allows for control of the adsorption state, facilitating release after the workpiece is moved into position. It is stable and convenient to use, and suitable for transferring small workpieces that are not convenient to hold from the side or to be magnetically adsorbed. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4A handheld suction cup includes a handle 1, a hand control valve 4 is installed at the upper end of the handle 1, and a suction cup 5 is connected to the lower end of the handle 1; the handle 1 is convenient for the operator to hold, and the negative pressure state of the suction cup 5 is controlled by the hand control valve 4.

[0025] The grip 1 has a through-hole 3, and the two ends of the through-hole 3 are respectively connected to the hand control valve 4 and the suction cup 5. The design of the through-hole 3 makes it easy to control the state of the suction cup 5 through the hand control valve 4, making it easy to control the suction and release of the suction cup 5, and making it convenient to pick up and release the workpiece.

[0026] The manual control valve 4 includes a valve body 41, a through hole 42 at the lower end of the valve body 41 that communicates with the air guide hole 3, and a pressure relief hole 43 on one side of the valve body 41 that communicates with the through hole 42. A piston rod 44 matching the through hole 42 is slidably disposed within the valve body 41, and a corresponding return spring 45 is provided. The side of the piston rod 44 can close the pressure relief hole 43. When the piston rod 44 is pressed, it closes the pressure relief hole 43, eliminating the negative pressure in the air guide hole 3. When the piston rod 44 is released, the return spring 45 causes the piston rod 44 to rise and return to its original position, connecting the pressure relief hole 43 with the through hole 42, thus relieving the negative pressure in the air guide hole 3 and the suction cup 5, allowing the workpiece to be released.

[0027] Based on the above technical solution, when dealing with workpieces that are difficult to hold from the side or difficult to assemble from the side, this handheld suction cup is used to pick up the end of the workpiece. During operation, hold the handle 1, press the piston rod 44 and hold (as shown in the attached diagram). Figure 3 As shown), press the suction cup 5 against the end of the workpiece. After the suction cup 5 adsorbs the workpiece, slightly loosen the piston rod 44. The return spring 45 drives the piston rod 44 upward, increasing the negative pressure difference between the air guide hole 3 and the suction cup 5, increasing the adsorption force on the workpiece, and ensuring the stability of picking up the workpiece.

[0028] When the workpiece is moved to the designated position, the piston rod 44 is released, and the return spring 45 extends and resets, causing the piston rod 44 to move upward until the pressure relief hole 43 connects with the through hole 42. That is, the suction cup 5 is connected to the outside through the pressure relief hole 43 to relieve the negative pressure. At this time, the suction cup 5 can detach from the workpiece, completing the transfer of the workpiece. By controlling the state of the suction cup 5 through the manual control valve 4, the adsorption and retrieval of the workpiece can be easily controlled, and the stability of the workpiece suction can be ensured, guaranteeing the stable transfer of the workpiece.

[0029] In this technical solution, such as Figure 1-4 As shown, the piston rod 44 extends out of the upper end of the valve body 41 and is provided with a pressing end 441, which facilitates pressing the piston rod 44, makes it easy to accurately control the position of the piston rod 44, and facilitates the use of the handheld suction cup.

[0030] In this technical solution, such as Figure 1-4 As shown, the upper end of the air guide hole 3 is provided with a mounting hole 31 for installing the valve body 41, and the valve body 41 is threadedly and sealed in the mounting hole 31. This facilitates the installation and replacement of the valve body 41, and also ensures the stability of the connection between the valve body 41 and the handle 1, ensuring a stable gripping state of the workpiece by the handheld suction cup.

[0031] In this technical solution, such as Figure 1-4 As shown, the lower end of the grip 1 is provided with a connecting end 2 corresponding to the suction cup 5, and the suction cup 5 is fitted onto the connecting end 2. This facilitates replacement when the suction cup 5 wears out, reducing usage costs. It also facilitates the replacement of different models of suction cup 5 for different workpieces, improving the stability and compatibility of picking up different types of workpieces and ensuring the adaptability of the handheld suction cup.

[0032] In this technical solution, such as Figure 1-4 As shown, the side wall of the grip handle 1 is covered with an anti-slip pad. This facilitates the operator's gripping and handling of the handheld suction cup, ensuring stability during use and improving the stability of workpiece handling.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
