Description

Technical Field

[0001] The present application relates to the technical field of gripping equipment, and in particular to a gripping mechanism for processing equipment. Background Art

[0002] The gripping mechanism of processing equipment is a mechanism used to grab and move workpieces. It is usually used in fields such as automated production lines and robots. The application range of the gripping mechanism of processing equipment is very wide, including automobile manufacturing, electronic manufacturing, food processing, medical equipment and other fields. With the continuous development of automation technology, the gripping mechanism of processing equipment will become more and more popular and become an indispensable and important part of automated production lines and robots and other fields.

[0003] With respect to the above-mentioned related technologies, the inventor believes that when it is necessary to grasp some long parts, it is difficult to ensure the stability of grasping with only one grasping point, and the stability of grasping can only be ensured by increasing the grasping force. However, when the grasping force is large, when encountering some relatively fragile parts, it is inevitable that the parts themselves will be damaged, causing economic losses to the user, and lacking certain practicality.

[0011] Preferably, two groups of mounting rods are fixedly mounted on the mounting box, round rods are fixedly mounted on the mounting rods, and the grabbing rods are movably sleeved on the round rods.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a processing equipment grasping mechanism. Figure 1-3A processing equipment grabbing mechanism comprises a mounting box 1, a driving rod 2 is movably arranged in the mounting box 1, a connecting plate 3 is fixedly installed on the driving rod 2, two groups of moving blocks 4 are symmetrically arranged on the connecting plate 3, two groups of connecting rods 5 are hingedly installed on the moving blocks 4, and a grabbing mechanism is hingedly installed on one end of the connecting rod 5 away from the moving block 4, a telescopic rod 6 is fixedly installed in the mounting box 1, a moving plate 7 matching with the mounting box 1 is fixedly installed on the output end of the telescopic rod 6, the driving rod 2 is fixedly installed on the moving plate 7, a guide groove 8 is opened on the connecting plate 3, guide blocks 9 matching with the guide groove 8 are fixedly installed on the moving blocks 4, and positive and negative screw rods 10 matching with the guide blocks 9 are rotatably installed on the connecting plate 3, and the grabbing mechanism comprises a grabbing rod 11 hinged with the connecting rod 5, and a rubber pad 12 is fixedly installed on the grabbing rod 11;

[0020] By adopting the above technical solution, the forward and reverse screw rods 10 are rotated, and the forward and reverse screw rods 10 cooperate with the guide grooves 8 and the guide blocks 9 to drive the two groups of moving blocks 4 to move in opposite directions. The connecting rods 5 are driven to move through the moving blocks 4, and then the two groups of grabbing rods 11 are driven to move in opposite directions. Therefore, the longitudinal distance between the two groups of grabbing rods 11 can be adjusted according to the length of the grasped parts, so that the clamping force can be distributed in a larger range, thereby ensuring the stability of the parts during the grasping process. By arranging rubber pads 12 on the grabbing rods 11, the friction between the grabbing rods 11 and the parts can be increased, thereby improving the stability of the grasping.

[0021] Reference Figure 1-3 Two sets of mounting rods 13 are fixedly mounted on the mounting box 1, round rods 14 are fixedly mounted on the mounting rods 13, and the grabbing rods 11 are movably sleeved on the round rods 14;

[0022] By adopting the above technical solution, the extension of the telescopic rod 6 is controlled, and the telescopic rod 6 drives the connecting plate 3 to move through the movable plate 7 in cooperation with the driving rod 2. The connecting plate 3 drives the two groups of movable blocks 4 to move through the guide groove 8 in cooperation with the guide block 9, and then drives the connecting rod 5 to drive the two groups of grabbing rods 11 to rotate. Since the rotation directions of the two groups of grabbing rods 11 are opposite, the parts can be clamped and grasped by the grabbing rods 11.

[0023] The implementation principle of a grasping mechanism of a processing equipment in the embodiment of the present application is as follows: the grasping mechanism is installed on the machine arm through the installation box 1, and the telescopic rod 6 is controlled to extend. The telescopic rod 6 drives the connecting plate 3 to move through the action of the moving plate 7 and the driving rod 2. The connecting plate 3 drives the two groups of moving blocks 4 to move through the guide groove 8 and the guide block 9, and then drives the connecting rod 5 to drive the two groups of grasping rods 11 to rotate. Since the rotation directions of the two groups of grasping rods 11 are opposite, the grasping rods 11 can be used to clamp and grasp the parts, and the positive and negative screw rods 10 are rotated. The rod 10 cooperates with the guide groove 8 and the guide block 9 to drive the two groups of moving blocks 4 to move in opposite directions, and the connecting rod 5 is driven to move through the moving block 4, thereby driving the two groups of grabbing rods 11 to move in opposite directions. Therefore, the longitudinal distance between the two groups of grabbing rods 11 can be adjusted according to the length of the grasped parts, so that the clamping force can be distributed in a larger range, thereby ensuring the stability of the parts during the grasping process. By arranging rubber pads 12 on the grabbing rods 11, the friction between the grabbing rods 11 and the parts can be increased, thereby improving the stability of the grasping.
