Description

Technical Field

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

[0002] Tooling, also known as process equipment, is a general term for various tools used in the manufacturing process. Fixtures are a type of tooling used to clamp workpieces or guide cutting tools. In the fields of machining, assembly, and automated production, workpiece clamping is a key link to ensure machining accuracy and production efficiency. Existing technologies rely on manual operation of fixtures (such as screw clamps, pressure plate clamps, etc.) during clamping, which is time-consuming and labor-intensive, making it difficult to meet the needs of mass production. Moreover, the consistency of manual operation is poor, and the clamping accuracy is significantly affected by the skill level of the workers. Therefore, a pneumatic rapid clamping device is provided. Utility Model Content

[0003] The purpose of this invention is to provide a pneumatic quick clamping device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic quick clamping device, comprising a tooling body, a workpiece being movably connected to the top of the tooling body, a central hole being provided inside the tooling body, and an installation groove being provided inside the central hole, a rotary pressing cylinder being installed inside the installation groove, a rotary pressure plate being installed at the top of the rotary pressing cylinder, and an air pipe connector being provided on one side of the rotary pressing cylinder.

[0005] Preferably, there are six sets of mounting slots and rotary pressing cylinders, and the mounting slots are arranged in a ring shape inside the central hole.

[0006] Preferably, the tooling body has an internal mounting hole, and a positioning pin is installed inside the mounting hole.

[0007] Preferably, the workpiece has a positioning hole inside, and the position of the positioning hole corresponds to the position of the positioning pin, and the positioning hole and the positioning pin form a movable connection.

[0008] Preferably, the rotating pressure plate has a through hole inside, and a nut is installed at the bottom end of the through hole, and an adjusting bolt is installed inside the nut.

[0009] Preferably, the adjusting bolt and the nut form a threaded connection, and a rubber pad is provided at the bottom end of the adjusting bolt.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) By setting a rotating pressure plate, a rotating pressing cylinder, a mounting groove, a positioning hole, a mounting hole and a positioning pin, the workpiece can be quickly clamped. The cooperation between the positioning hole and the positioning pin makes it easy to place the workpiece accurately and quickly on the fixture body, preventing the workpiece from shifting. At the same time, the six sets of rotating pressing cylinders are arranged in a ring shape, using compressed air as a power source. The movement of the cylinder drives the rotating pressure plate to move, realizing the quick clamping and releasing of the workpiece, ensuring the consistency of workpiece clamping, thereby improving the clamping accuracy.

[0012] (2) By setting an adjusting bolt, through hole, nut and rubber pad, workpieces of different thicknesses can be clamped. The threaded connection between the adjusting bolt and the nut can adjust the adjusting bolt to move vertically inside the through hole and change the height of the rubber pad to adapt to workpieces of different thicknesses. The setting of the rubber pad avoids damage to the surface of the workpiece during the clamping process, thereby improving the product processing quality. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 An embodiment of this utility model is provided: a pneumatic quick clamping device, including a tooling body 1, a workpiece 2 movably connected to the top of the tooling body 1, a central hole 4 provided inside the tooling body 1, and an installation groove 6 provided inside the central hole 4, a rotary pressing cylinder 5 installed inside the installation groove 6, a rotary pressing plate 3 installed at the top of the rotary pressing cylinder 5, and an air pipe connector 9 provided on one side of the rotary pressing cylinder 5.

[0023] Both the mounting slot 6 and the rotary pressing cylinder 5 are provided with six sets. The mounting slot 6 is arranged in a ring shape inside the central hole 4. The tooling body 1 is provided with mounting holes 10, and the mounting holes 10 are installed with positioning pins 11. The workpiece 2 is provided with positioning holes 8, and the position of the positioning holes 8 corresponds to the position of the positioning pins 11. The positioning holes 8 and the positioning pins 11 form a movable connection. The cooperation between the positioning holes 8 and the positioning pins 11 makes it easy to place the workpiece 2 accurately and quickly on the tooling body 1, preventing the workpiece 2 from shifting.

[0024] Specifically, as shown in the figure, during use, six sets of rotating pressing cylinders 5 are arranged in a ring. Compressed air is used as the power source. The movement of the cylinders drives the rotating pressure plate 3 to quickly clamp and release the workpiece, ensuring the consistency of workpiece 2 clamping.

[0025] The rotating pressure plate 3 has a through hole 12 inside, and a nut 13 is installed at the bottom of the through hole 12. An adjusting bolt 7 is installed inside the nut 13. The adjusting bolt 7 and the nut 13 form a threaded connection. A rubber pad 14 is provided at the bottom of the adjusting bolt 7 to avoid damage to the surface of the workpiece 2 during the clamping process.

[0026] Specifically, as shown in the figure, during use, by adjusting the threaded connection between the adjusting bolt 7 and the nut 13, the adjusting bolt 7 can be adjusted to move vertically inside the through hole 12, thereby changing the height of the rubber pad 14 to accommodate workpieces 2 of different thicknesses.

[0027] Working principle: In use, firstly, the pneumatic quick clamping device is transported to the target area for installation. According to the thickness of the workpiece 2, the height of the rubber pad 14 is adjusted by controlling the rotation of the adjusting bolt 7 to move vertically inside the through hole 12, changing the height of the rubber pad 14 to accommodate workpieces 2 of different thicknesses. Then, the workpiece 2 to be processed is taken and placed on the fixture body 1. The positioning hole 8 on the workpiece 2 is aligned with the positioning pin 11, and the workpiece 2 is placed accurately and quickly on the fixture body 1 to prevent the workpiece 2 from shifting. Next, the air source equipment is controlled to operate. Six sets of rotating pressing cylinders 5 are arranged in a ring. Compressed air is used as the power source. The movement of the cylinders drives the rotating pressure plate 3 to move, realizing the quick clamping and release of the workpiece 2. Finally, the use of the pneumatic quick clamping device is completed.
