Description

A pneumatic chuck

technical field

The invention relates to the technical field of round formwork wood board processing equipment, in particular to a pneumatic chuck clamp.

Background technique

When making packaging boxes, in order to accurately make some special shapes, it is necessary to make a cutting line first. The cutting line is processed on a round die, and the round die is fixed on the machine tool with a round die support plate. In the prior art, every time a round template is processed, when replacing the workpiece, it is necessary to use a wrench to tighten and loosen each screw one by one to complete the loading and unloading of the workpiece, so that the round mold support plate is fixed. This method is extremely time-consuming and laborious. Also greatly reduced production efficiency.

Contents of the invention

The purpose of the present invention is to provide a pneumatic chuck clamp to solve the above technical problems.

In order to solve the above problems, the technical solution adopted in the present invention is:

A pneumatic chuck clamp is characterized in that it includes a base, a cylinder frame, a driving cylinder, a driving arm, a connecting block, and a moving wheel; the base includes a cylinder and a fixed plate fixed at one end of the cylinder; the cylinder frame is fixed on On the fixed plate of the base, the cylinder body of the driving cylinder is fixed on the cylinder frame; the moving wheel is in a ring structure, which is sleeved on the cylinder of the base, and the thickness of the part downwards in the middle is gradually reduced to form an inclined plane; the moving wheel The middle part of the outer wall is connected to one end of the connecting block through a pin; the other end of the connecting block is connected to the top of the driving arm through a pin; the upper part of the driving arm is connected to the cylinder of the base through a pin; the driving arm The lower end is connected to the front end of the piston rod of the drive cylinder.

Further speaking: the lower end of the driving arm is provided with a long hole, and the long hole is assembled on the connecting shaft on the front end of the piston rod.

Beneficial effects: Compared with the prior art, the pneumatic chuck clamp described in the present invention can replace the traditional way of using manual loose screws, and when the workpiece needs to be changed, the clamping of the round mold support plate can be realized by controlling the driving cylinder It saves time and effort, greatly improves production efficiency, and has a good application prospect.

Description of drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Example:

Referring to FIG. 1 , the pneumatic chuck clip described in this embodiment includes a base, a cylinder frame 2 , a driving cylinder 3 , a driving arm 5 , a connecting block 6 , and a moving wheel 7 . The base includes a cylinder 1B and a fixed plate 1A fixed at one end of the cylinder 1B; the cylinder frame 2 is fixed on the fixed plate 1A of the base, and the cylinder body of the driving cylinder 3 is fixed on the cylinder frame 2; The moving wheel 7 has a ring structure and is sleeved on the cylinder 1B of the base, and the thickness of the downward portion of the center decreases gradually to form an inclined plane. The middle part of the outer wall of the moving wheel 7 is connected to one end of the connecting block 6 through a pin; the other end of the connecting block 6 is connected to the top of the driving arm 5 through a pin; the top of the driving arm 5 is connected to the base through a pin 5A on the cylinder 1B. The lower end of the driving arm 5 is connected to the front end of the piston rod 4 of the driving cylinder 3. Specifically, the lower end of the driving arm 5 is provided with a long hole, and the long hole is assembled on the front end of the piston rod 4. Connect to shaft 5B.

In order to prevent the moving wheel 7 from running off when moving on the cylinder 1B, two driving arms 5 can be arranged symmetrically, which are respectively located on both sides of the moving wheel 7, and the tops of the two driving arms 5 are respectively connected to the moving wheel 7 through a connecting block. this is okay. Of course, the driving arm 5 can also be designed as a U-shaped structure, and the two top ends are respectively connected to the moving wheel 7 through the connecting block, and the lower parts of the two support arms are respectively provided with long holes, and assembled on the two front ends of the piston rod 4. On the connecting shaft 5B on the side.

The pneumatic chuck clamp described in the present invention can replace the traditional method of using manual elastic screws. When in use, the base is fixed on the main shaft of the machine tool, the cylinder frame 2 is fixed on the fixed plate 1A of the base by screws, and the driving cylinder 3 is fixed. Installed on the cylinder frame 2, use the drive cylinder 3 to clamp and loosen the round die support plate by reciprocatingly pulling the drive arm 5. Therefore, when the workpiece needs to be changed, just press the button that controls the drive cylinder lightly to realize the clamping and loosening of the round die support plate, which saves time and effort and greatly improves production efficiency.

The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structures made using the description of the present invention and the contents of the accompanying drawings are directly or indirectly used in other related technical fields, and are equally applicable to the present invention. within the scope of patent protection.
