[0001] This utility model relates to the field of machining technology, and in particular to a pneumatic clamp for machining tool holes. Background Technology

[0002] A fixture is a device that plays an auxiliary role in the machining process. It is used to fix the workpiece to be processed and guide the machining operation. During the machining of parts, the positioning stability, ease of operation and processing efficiency of the fixture directly determine the machining quality and production rhythm of the parts.

[0003] In the existing technology, the machining fixtures for this type of part have the following shortcomings: the part plane may not be properly positioned during clamping, and there may also be positioning errors between the fixture and the side hole position of the part. Utility Model Content

[0004] In view of this, this application proposes a pneumatic fixture for machining tool holes, which can ensure the positioning of side holes and avoid the possibility of mispositioning during clamping.

[0005] This utility model provides the following technical solution: a pneumatic fixture for machining tool holes, characterized in that it includes: a base, a cylinder, a fixed seat, a fixture, and a positioning pin; The base plate is a rectangular flat plate structure, the clamp is located on the upper surface of the base plate, and the clamp can slide on the base plate; The fixing seat has an L-shaped cross-section and is located on one side of the clamp. The fixing seat includes a first fixing part and a second fixing part. The first fixing part has a mounting groove on one side, which is suitable for placing parts. The positioning pin has a cylindrical structure, and positioning grooves are respectively provided at corresponding positions of the first fixing part and the second fixing part. The positioning pin is embedded in the positioning groove to assist in the positioning of the part. The cylinder is located on the lower surface of the base plate, is fixedly connected to the base, and drives the clamp to move, pushing the clamp to clamp the part.

[0006] In one embodiment of the utility model, a compression spring screw is also included; There are two spring screws, located at the ends of the first fixing part and the second fixing part respectively, and arranged beside the pin hole to help fix the positioning pin and prevent the positioning pin from shifting.

[0007] In one embodiment of the utility model, there are two fixing seats, which are respectively fixed on both sides of the base, and the clamp is located between the two fixing seats.

[0008] In one embodiment of the utility model, the positioning groove is located on one side of the two fixed seats near the clamp, and the two second fixing parts are arranged opposite each other.

[0009] In one embodiment of the utility model, the clamp includes a KO clamp, a first aluminum jaw, and a second aluminum jaw; The KO clamp is located between the first aluminum jaw and the second aluminum jaw, and the KO clamp has an inverted trapezoidal cross-section. The KO clamp is connected to the first aluminum jaw and the second aluminum jaw by bolts.

[0010] In one embodiment of the utility model, the cylinder drives the KO clamp to move vertically, and when the KO clamp moves downward, the first aluminum jaw and the second aluminum jaw move outward synchronously to fix the length direction of the part.

[0011] In one embodiment of the utility model, a support is also included.

[0012] There are two supports, which are placed side by side to support the base plate.

[0013] In one embodiment of the utility model, the bracket is a long strip-shaped plate-like component with a rectangular rounded corner through hole in the middle and symmetrical arc-shaped notches on both sides along the length direction.

[0014] In one embodiment of the utility model, the first fixing part and the second fixing part are rigidly fixedly connected to form an L-shaped body.

[0015] In one embodiment of the utility model, the fixing base is connected to the base plate by bolts.

[0016] The beneficial effects of this utility model are as follows: By setting an L-shaped fixed seat, placing the part, and opening an installation groove to match the shape of the part to achieve initial positioning, a positioning pin is used to pass through the pin hole of the part and be embedded in the positioning groove. With the help of a compression spring screw, the positioning pin is prevented from shifting. The multi-positioning structure greatly improves the positioning accuracy of the part. At the same time, the cylinder drives the movement of the clamp. The inverted trapezoidal structure of the KO clamp drives the first and second aluminum jaws to move outward synchronously, realizing stable clamping of the part in the length direction. This not only ensures that the clamping force is uniform and controllable, but also avoids the deformation of the part, and improves efficiency by replacing manual operation. The two fixed seats are symmetrically arranged on both sides of the base, and the clamp is located in the middle, which is suitable for processing symmetrical parts and reduces the footprint. The support and base plate structure of the base are stable. The through hole and recess design of the support reduces weight while ensuring support strength, and the overall stability and reliability of hole processing are improved.

[0025] Specific references Figures 1-4 As a pneumatic fixture for machining tool holes according to this utility model, the device includes: a base plate 111, a cylinder 151, a fixed base, a clamp, and a positioning pin 141; the base plate 111 is a rectangular flat plate structure, the clamp is located on the upper surface of the base plate 111, and the clamp can slide on the base plate 111; the fixed base has an L-shaped cross section and is located on one side of the clamp, and the fixed base includes a first fixing part 131 and a second fixing part 133, and a mounting groove is provided on one side of the first fixing part 131 for placing part 132; the positioning pin 141 is a cylindrical structure, and positioning grooves are respectively provided at corresponding positions of the first fixing part 131 and the second fixing part 133, and the positioning pin 141 is embedded in the positioning groove to assist in positioning part 131; the cylinder 151 is fixedly connected to the base and drives the clamp to move, pushing the clamp to clamp part 132.

[0026] This example also includes two compression spring screws 122. The two compression spring screws 142 are located at the ends of the first fixing part 131 and the second fixing part 133, respectively, and are arranged beside the pin hole. During processing, for ease of installation, the positioning groove is made wider than the positioning pin 141. After the positioning pin 141 passes through the pin hole of the part 132 and is fitted into the positioning groove, the compression spring screws 122 can provide auxiliary fixation for the positioning pin 141, effectively preventing the positioning pin 141 from shaking or shifting within the positioning groove, further improving positioning accuracy.

[0027] In this example, the fixture includes a KO clamp 121, a first aluminum jaw 122, and a second aluminum jaw 123. The KO clamp 121 is located between the first aluminum jaw 122 and the second aluminum jaw 123, and its cross-section is an inverted trapezoid. The three parts are connected by bolts. A cylinder 151 drives the KO clamp 121 to move vertically. When the KO clamp 121 moves downward, its inverted trapezoidal structure pushes the first aluminum jaw 133 and the second aluminum jaw 123 to move outward synchronously, thereby achieving stable clamping of the part 132 along its length. This clamping method ensures uniform and controllable clamping force, preventing deformation of the part due to uneven force, and can replace manual operation, improving clamping efficiency.

[0028] In this example, there are two fixing seats, one on each side of the base, and the clamp is located between the two fixing seats. The first fixing part 131 and the second fixing part 133 of each fixing seat are rigidly connected to form an L-shaped body. This rigid connection method can enhance the overall structural strength of the fixing seat and avoid deformation due to excessive clamping force on the parts. The second fixing parts 133 of the two fixing seats are arranged opposite each other, and the positioning groove is located on the side of the two fixing seats closer to the clamp, which is suitable for the processing requirements of symmetrical structural parts, while reducing the lateral space occupied by the device, thus providing convenience for processing and production.

[0029] In this example, the base specifically includes a bracket 112 and a base plate 111. The base plate 111 has a plate-like structure, with the cylinder 151 located below it, and the fixing seat and clamp positioned on the other side of the base plate 111. Two brackets 112 are placed side-by-side to support the base plate 111. Each bracket 112 is a long, strip-shaped plate with a rectangular, rounded-corner through-hole in the center and symmetrically arranged arc-shaped notches on both sides along its length. This structure reduces the overall weight of the base while ensuring support strength, providing a stable load-bearing foundation for the entire device. The fixing seat is bolted to the base plate 111 to ensure that the fixing seat does not shift during processing.

[0030] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
