Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of packaging equipment, and particularly relates to a cargo clamping tool for packaging equipment. Background Art
[0002] In packaging equipment, when transferring goods, a clamping tool, that is, a chuck, is needed to clamp the goods. For ease of use, an automatically driven fixture is generally used to clamp the goods. Automatic fixtures are an automated equipment that is mainly used to clamp and process various parts and products. Compared with traditional manual fixtures, automatic fixtures have higher precision and efficiency, which can greatly improve production efficiency and product quality. Automatic fixtures are usually composed of fixture bodies, pneumatic systems, control systems, and sensors. The fixture body is used to clamp the workpiece, and usually uses various fixture elements and clamping claws to quickly and accurately position and fix the workpiece. The pneumatic system provides power for the fixture, and realizes the extension and clamping of the fixture elements through air pressure regulation and control. The control system is the brain of the automatic fixture, which is used to control the workflow and motion trajectory of the fixture to ensure that the fixture can work accurately according to the preset program. The sensor is used to detect information such as the position and posture of the workpiece, and feed the signal back to the control system so that the workpiece can be accurately positioned and clamped.
[0003] In the existing electric chuck, the chuck body and the power actuator are connected in an integrated manner. In the integrated connection mode, there are various interaction forces between the chuck body and the power actuator, including stress, strain and torque, etc., and the interaction forces such as stress, strain and torque produce certain defects in the object. These defects may have a negative impact on the structure and function of the object, such as:
[0004] Stress concentration: When an object is subjected to external or internal forces, stress will be generated inside it. If the stress distribution in the object is uneven, the stress value in some areas will increase abnormally, resulting in local stress concentration. This stress concentration area may cause the formation and expansion of microcracks, and eventually lead to the fracture or failure of the object;
[0005] Uneven strain: When an object is subjected to external forces, strain will be generated inside it. If the strain is unevenly distributed in different areas, the object will be deformed, such as twisting, bending or warping. This uneven strain not only affects the shape and dimensional accuracy of the object, but may also cause local stress concentration, further accelerating the damage of the object;
[0006] Torque fracture: When an object is subjected to torque, it may cause the shear stress inside the object to increase. If the shear stress exceeds the shear strength of the object, shear fracture will occur. This type of fracture usually occurs in the slender part or thin-walled area of the object, causing the integrity and stability of the object's structure to be destroyed; Utility Model Content
[0007] The purpose of the utility model is to provide a cargo clamping tool for packaging equipment, which can avoid the influence of interaction forces such as stress, strain and torque on the clamp body and the electric actuator, thereby avoiding damage.
[0008] The technical solutions adopted in this utility are as follows:
[0009] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure is hinged on the base, and the interlocking structure is hinged on the base with two interlocking structures.
[0010] A protective sheet is fixedly connected to the inner side of the bottom of the clamping claw, and the clamping claw can clamp the goods through the protective sheet.
[0011] The technical effects achieved by this utility model are:
[0012] The cargo clamping tooling of this practical packaging equipment can transmit the driving force by means of a fitted disc, thereby avoiding direct contact and connection between the clamping claws and the pull-out connecting rod, and thus no forces such as stress, strain and torque are generated. This can avoid the interaction forces such as stress, strain and torque from affecting the clamp body and the electric actuator, thereby avoiding damage.
[0013] The cargo clamping tooling of the practical packaging equipment utilizes a protective sheet made of a high-hardness material to protect the safety of the clamping claws, avoid damage to the inner sides of the clamping claws and cargo caused by contact, and ensure the safety of the clamping claws.

[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.
[0020] like Figures 1 to 3As shown, a cargo clamping tool comprises a mounting plate 1, which is a bearing member of the entire chuck. The entire chuck is mounted on the mounting plate 1. A cylinder 2 is arranged in the air on the top of the mounting plate 1. The cylinder 2 is a power actuator of the clamp and can provide power for the device under the premise of external high-pressure gas. The bottom of the cylinder 2 is fixed to the top of the mounting plate 1 through two connecting rods, so that the cylinder 2 is away from the mounting plate 1. The output end of the bottom of the cylinder 2 is fixedly connected with a pull-out connecting rod 3. The pull-out connecting rod 3 passes through the holes on the surface of the mounting plate 1 and extends downward. The pull-out connecting rod 3 is a transmission component that can transmit the power output by the cylinder 2 downward. The bottom of the mounting plate 1 is fixedly connected with an upper fixing seat 4, and the bottom of the upper fixing seat 4 is fixedly connected with The sleeve rod 5, the bottom of the sleeve rod 5 is fixedly connected with a lower fixed seat 6, the upper fixed seat 4, the sleeve rod 5 and the lower fixed seat 6 are all hollow annular settings, the pull-out connecting rod 3 is sleeved in the upper fixed seat 4, the sleeve rod 5 and the lower fixed seat 6, the pull-out connecting rod 3 can slide inside the upper fixed seat 4, the sleeve rod 5 and the lower fixed seat 6, the upper fixed seat 4, the sleeve rod 5 and the lower fixed seat 6 can achieve a connection effect without affecting the transmission of the pull-out connecting rod 3, the bottom of the lower fixed seat 6 is fixedly connected with a limiting block 7, both sides of the limiting block 7 are fixedly connected with side plates 8, the limiting block 7 is a component used to limit the side plates 8, which can be used to ensure the spacing between the two side plates 8, and the side plates 8 are important components of the connecting fixture, the two side plates There are two evenly distributed rotating shafts 9 fixedly connected between 8, and the rotating shaft 9 is the shaft body for the clamp to rotate. The surface of the rotating shaft 9 is provided with a clamping jaw 10, and the clamping jaw 10 can rotate around the rotating shaft 9. The two clamping jaws 10 are arranged in a scissor-like manner. The bottom of the pulling connecting rod 3 passes through the limit block 7 and is fixedly connected with a cross bar 11. The cross bar 11 is a component for squeezing the clamping jaw 10, and the top of the clamping jaw 10 can be squeezed under the drive of the pulling connecting rod 3. The two sides of the cross bar 11 and the top of the clamping jaw 10 are fixedly connected with a rotating rod 12, and the two sides of the surface of the rotating rod 12 are movably connected with discs 13. The number of discs 13 is two and they are evenly distributed at both ends of the rotating rod 12. The discs 13 can rotate on the surface of the rotating rod 12. 13 is located on both sides of the cross bar 11 and the clamping jaw 10. The two adjacent discs 13 on the cross bar 11 and the clamping jaw 10 can fit together. When the pull-out link 3 is pressed down, the cross bar 11 can drive the discs 13 at two positions to fit together, so that the discs 13 on both sides of the cross bar 11 can squeeze the discs 13 on both sides of the clamping jaw 10, and then the guiding effect of the arc can be used to squeeze the movable clamping jaw 10, so that the top of the scissor-type clamping jaw 10 rotates outward and the bottom rotates inward, and the goods are clamped at the bottom. When the clamping work is in progress, the power is transmitted through the contact of the discs 13, and the pull-out link 3 is not directly in contact with the clamping jaw 10, so no stress, strain, torque and other forces will be generated.
[0021] like Figure 2As shown, a protective sheet 14 is fixedly connected to the inner side of the bottom of the clamp 10, and the clamp 10 can clamp the goods through the protective sheet 14. The protective sheet 14 is made of a high-hardness material. The protective sheet 14 made of a high-hardness material can protect the safety of the clamp 10, avoid damage to the inner side of the clamp 10 from contact with the goods, and ensure the safety of the clamp 10.
[0022] like Figure 1 and Figure 2 As shown, four evenly distributed holes are provided on the surface of the mounting plate 1, one of which is used to install the pull-out connecting rod 3, and the other three holes cooperate with screws to enable the device to be installed conveniently and quickly.
[0023] like Figure 3 As shown, the distance between the discs 13 on both sides of the crossbar 11 is smaller than the distance between the discs 13 at the top of the two clamping jaws 10, so that the discs 13 at the top can easily squeeze the discs 13 at the bottom outwards, ensuring the accuracy of the clamping jaws 10.
[0024] like Figure 3 As shown, a smooth layer is fixedly connected around the surface of the disc 13, and the smooth layer is a glaze surface. The smooth layer can be used to reduce the friction between the discs 13 and prevent the discs 13 from being easily worn.
[0025] like Figure 3 As shown, a torsion spring is sleeved on the surface of the rotating shaft 9, and the clamping jaw 10 is fixedly connected to the surface of the rotating shaft 9 through the torsion spring. The restorability of the torsion spring after being stressed can be utilized to make the clamping jaw 10 resettable, thereby increasing convenience during use.
[0026] The working principle of the utility model is as follows: when in use, the cylinder 2 extends and contracts downward to drive the pull-out connecting rod 3 to move, and the sliding of the pull-out connecting rod 3 inside the upper fixed seat 4, the sleeve rod 5 and the lower fixed seat 6 drives the cross bar 11 to move downward, thereby driving the discs 13 at the two positions to squeeze each other, and then utilizing the guiding effect of the arc to squeeze the movable clamping jaws 10, so that the top of the scissor-type clamping jaws 10 rotate outward and the bottom rotates inward, and the goods are clamped at the bottom. When the clamping work is in progress, the power is transmitted through the contact of the discs 13, and the pull-out connecting rod 3 is not directly in contact with the clamping jaws 10, so no stress, strain, torque and other forces are generated.
[0027] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
