Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to a clamping assembly for a three-axis machining center. Background Technology

[0002] Currently, when machining parts on a three-axis machining center, it is necessary to perform machining on the surface of the part by moving the tool along the X, Y, and Z axes. However, the part cannot move on the clamping assembly used in the three-axis machining center; it is fixed to the clamping fixture. If machining is required on different planes of the part, the clamping position of the part needs to be changed. However, if a part with a special shape is encountered, the caliper on the machining center cannot clamp it. For example, when drilling holes on the thick surface of a sheet metal, the three-axis machining center cannot currently fix the sheet metal perpendicular to the mounting plane of the machining center. This requires the use of a five-axis machining center, but the purchase cost of a five-axis machining center is high, its utilization rate is low, and it increases the manufacturing cost of the parts. Utility Model Content

[0003] The purpose of this invention is to provide a clamping assembly for a three-axis machining center, which solves the problem that the tooling on a three-axis machining center may fail to clamp when the workpiece is being machined at different positions.

[0004] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a clamping assembly for a three-axis machining center, including a base, on which a fixture is provided. The fixture has a positioning hole and a screw hole. A crimping bolt passes through a pressure plate and is screwed into the screw hole. A positioning pin is inserted into the positioning hole and abuts against the part. The pressure plate is pressed against the part. The base is mounted on the machine bed of the machining center, and the side of the part faces the machining tool of the machining center.

[0005] Preferably, the positioning holes are arranged in a matrix, and the screw holes are arranged in a matrix.

[0006] Preferably, the positioning holes and the screw holes are alternately arranged on the tooling surface.

[0007] Preferably, the machining center bed surface is provided with a sliding groove, a fixing bolt is provided in the sliding groove, a fixing plate is screwed onto the fixing bolt, and the fixing plate is pressed onto the base.

[0008] Preferably, the fixing plate has a first through hole, the base has a first connecting hole, and the first bolt passes through the first through hole and is screwed into the first connecting hole.

[0009] Preferably, the first through hole is elongated.

[0010] Preferably, a rib is installed between the base and the tooling.

[0011] Preferably, a lifting ring is installed on the upper side of the tooling.

[0012] Preferably, the pressure plate has a rotating hole, and a rotating pin is inserted into the rotating hole and the rotating pin is inserted into the positioning hole.

[0013] Preferably, the tooling, the rib, and the base are connected by welding.

[0014] Beneficial effects: The part is attached to the tooling so that the side of the part, which is also the surface to be machined, faces the machining tool. The position of the part is positioned by the locating pin, and then the part is fixed by the pressure plate to prevent the tool from shaking during machining. The tool that can move in three axes can be machined on the side of the part, and the part can be machined on different machining surfaces on the three-axis machining center. The three-axis machining center using the clamping assembly can complete the machining of different parts planes, replacing the use of a five-axis machining center, and reducing the machining cost of the part.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0018] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between 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.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0021] Under current technology, the position of a part on a three-axis machining center cannot be changed, resulting in only the surface of a single part being machined. If the side of a part needs to be machined, it needs to be placed on a five-axis machining center. If a plate-shaped part is to be machined, the thickness of the plate cannot be machined on a three-axis machining center. The fixtures on current three-axis machining centers cannot fix the plate perpendicular to the machining center bed surface so that the thickness of the plate faces the machining tool, allowing the tool to machine the side of the plate.

[0022] To solve the above problems, such as Figure 1 As shown, this utility model provides a clamping assembly for a three-axis machining center, including a base 1, a fixture 2 on the base 1, a positioning hole 21 and a screw hole 22 on the fixture 2, a crimping bolt 3 passing through a pressure plate 20 and screwed into the screw hole 22, a positioning pin 4 inserted into the positioning hole 21, the positioning pin 4 abutting against the part 5, the pressure plate 20 crimping against the part 5, the base 1 being mounted on the machining center bed 6, and the side of the part 5 facing the machining tool of the machining center.

[0023] The base 1 of this utility model can be freely installed on the machining center bed 6 and fixed. The workpiece 5 is positioned on the tooling 2 by the positioning pin 4. Then, the workpiece 5 is fixed by the pressure plate 20 on the crimping bolt 3, so that the workpiece 5 can be stably installed on the tooling 2. During the machining process, the workpiece 5 can be prevented from moving. The cutting tool keeps the workpiece 5 stable during the machining process.

[0024] by Figure 1 Taking a semi-circular part 5 as an example, if the front of the semi-circular part 5 needs to be machined, the surface of the fixture 2 that is in contact with the part 5 is placed on the front perpendicular to the machining tool, and fixed by the fixing bolt 7 on the machining center. If the side of the semi-circular part 5 needs to be machined, the surface of the fixture 2 that is in contact with the part 5 is placed parallel, so that the thickness surface of the semi-circular part 5 faces the machining tool, making it easier to machine the side of the semi-circular part 5 with the machining tool. This eliminates the need for a five-axis machining center, reducing the manufacturing cost of the part 5. The clamping assembly used in the three-axis machining center allows the part 5 to remain fixed after changing its position, enabling the three-axis machining center to machine different surfaces on the part 5 and to position the part 5 after changing its machining position.

[0025] The tooling 2 of this utility model is provided with multiple positioning holes 21 and screw holes 22. The positioning holes 21 are arranged in a matrix and the screw holes 22 are arranged in a matrix. This allows for the free fixing of parts 5 of different shapes. The positioning pins 4 can be installed in a suitable position through the positioning holes 21 on the tooling 2, so that the parts 5 can be positioned. Then, the bolts and pressure plates 20 are selected in a suitable position through the screw holes 22, and the parts 5 are fixed by the pressure plates 20, thus realizing the pressing and fixing of the parts 5.

[0026] Positioning holes 21 and screw holes 22 are alternately arranged on the surface of tooling 2. In order to make the positioning holes 21 and screw holes 22 evenly distributed, the positioning holes 21 and screw holes 22 are alternately arranged so that the positioning pins 4 and bolts can be selected in more positions, making it easier for tooling 2 to fix parts 5 of different shapes.

[0027] The machining center bed 6 of this utility model has a sliding groove 61, a fixing bolt 7 is provided in the sliding groove 61, a fixing plate 8 is screwed onto the fixing bolt 7, and the fixing plate 8 is pressed onto the base 1.

[0028] By fastening the fixing bolt 7, the fixing plate 8 on the fixing bolt 7 can be fixed to the base 1, so that it can be fixed on the slide 61 on the machining center. As the fixing bolt 7 moves in the slide 61, the installation position of the fixing bolt 7 can be changed, so that the base 1 can be flexibly fixed on the bed surface 6 of the machining center, with higher adaptability.

[0029] The fixing plate 8 has a first through hole 81 and the base 1 has a first connecting hole. The first bolt passes through the first through hole 81 and is screwed into the first connecting hole. The first bolt can further increase the connection between the fixing plate 8 and the base 1, improve the fixing ability, and make the base 1 more stably installed on the machining center bed 6.

[0030] The first through hole 81 is elongated. By setting the elongated first through hole 81, the installation position of the first bolt in the first through hole 81 can be changed, so that the base 1 can be connected to the fixing plate 8 through the first bolt in the first through hole 81, no matter where the base 1 is on the bed surface 6.

[0031] A rib plate 9 is installed between the base 1 and the fixture 2. By setting the rib plate 9, the rigidity between the base 1 and the fixture 2 can be increased, and the fixture 2 can be prevented from falling off or bending.

[0032] The tooling 2 is equipped with a lifting ring 10. Since the clamping component is heavy, it is usually moved by a lifting device. However, by adding the lifting ring 10, the clamping component can be moved freely. The clamping component used in the three-axis machining center is easy to move.

[0033] The pressure plate 20 has a rotating hole, and a rotating pin 201 is inserted into the rotating hole. The rotating pin 201 is inserted into the positioning hole 21. The middle section of the pressure plate 20 is fixed by the pressing bolt 3, while the side of the pressure plate 20 away from the part 5 is fixed by the rotating hole, so that the pressure plate 20 can rotate freely around the rotating pin 201 and change the pressing position to adapt to parts 5 of different sizes.

[0034] Tooling 2, rib 9 and base 1 are connected by welding, which increases the structural strength of the clamping assembly.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
