Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, specifically a workpiece clamping and rapid positioning device for machine tools. Background Technology

[0002] Machine tools are equipment used to manufacture or process materials such as metals, plastics, and wood. They are a crucial type of machinery in industrial production and are widely used in various fields, such as automobile manufacturing, aerospace, electronic equipment, and energy.

[0003] When machining parts, machine tools need to use positioning devices to clamp the parts. Most existing machine tool clamping and quick positioning devices use rigid fixtures to fix the parts. When fixing irregularly shaped parts, rigid fixtures cannot effectively wrap the outer surface of the parts, and the parts may slide during machining. When fixing parts of different sizes, it may be necessary to change the fixtures. The disassembly steps of existing positioning devices are complicated, and adjusting the position of the parts often requires disassembling the parts for adjustment, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a workpiece clamping and rapid positioning device for machine tools, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a workpiece clamping and rapid positioning device for a machine tool, comprising a frame, the frame being a cross-shaped component, with openings through at both ends and both sides of the frame, displacement blocks being provided at the openings at both ends and both sides of the frame, and several columns being installed on the surfaces of the four displacement blocks facing the center of the frame, a connector being provided at the center of the frame, a motor being provided at the bottom end of the connector, a base being provided on the outer surface of the motor, a slider being provided at the bottom end of the base, and a guide rail being installed at the bottom of the slider.

[0006] Preferably, the frame is provided with limiting rails at both ends and opposite ends of the two side openings. The bottom of the displacement block extends into the opening. Both sides of the extension end of the displacement block are provided with slots that match the limiting rails. The slots and limiting rails work together to limit the displacement block, so that the displacement block can be driven to make linear movements and apply clamping force to the part.

[0007] Preferably, an electric push rod is provided at one end of the displacement block facing the outside of the frame. Two uprights are connected between the electric push rod and the outer surface of the frame. The fixed end of the electric push rod is fixed by the uprights, and the output end of the electric push rod drives the corresponding displacement block to move.

[0008] Preferably, one end of each of the columns extends into the interior of the corresponding displacement block, and each of the extended ends of the columns is provided with a spring. When the four displacement blocks move to apply clamping force to the part, the columns contact the edge of the part. If the part is irregularly shaped, the protrusions on the edge of the part will squeeze the columns, causing some of the columns to contract into the displacement block, ensuring that the protrusions on the edge of the part are locked and ensuring tightness of fixation. The contracted columns squeeze the springs, and after the part is released, the springs push the columns to reset the columns.

[0009] Preferably, a pad is provided on the outer surface of the connector below the frame, and four screws are provided at the top of the pad. The top of each of the four screws extends through the frame. The pad supports the frame, and the screws limit the frame. After the frame is fitted onto the outside of the screws, screws are installed at the extended ends of the screws for reinforcement, so that the frame is fixed tightly and can be disassembled for maintenance.

[0010] Preferably, a support plate is provided at the bottom end of the guide rail, the support plate fixes the guide rail, and the support plate can be installed on the machine tool to fix the positioning device in a predetermined position.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This workpiece clamping and quick positioning device for machining tools uses four displacement blocks set at the top of the frame. The four displacement blocks move linearly at the top of the frame to clamp the workpiece. One end of the four displacement blocks is set with several retractable columns facing the middle of the frame. When the columns come into contact with the outer surface of the irregular workpiece, they are squeezed and retract into the displacement blocks, covering the protrusions at the edges of the workpiece, so that the workpiece is tightly fixed and the irregular workpiece can be clamped without displacement during processing.

[0013] 2. This workpiece clamping and quick positioning device for machine tools has an easily detachable frame that can be replaced for parts of different sizes without disassembling the parts connected to the machine tool. The operation is simple and reduces the probability of part damage.

[0014] 3. This workpiece clamping and quick positioning device for machining tools uses a rotatable connector and guide rail. The guide rail and machine tool conveying components are arranged in a cross shape. When the part is clamped for processing, the position of the part can be adjusted by the rotation of the connector and the linear movement of the guide rail. This makes it easy to adjust the position of the part, so that the part is directly below the machine tool operating components. The operation steps are simple and there is no need to frequently disassemble and assemble the part. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, 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 used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 3As shown, this embodiment of the workpiece clamping and rapid positioning device for machining tools includes a frame 1, which is a cross-shaped component. Openings are provided at both ends and sides of the frame 1. Displacement blocks 3 are provided at the openings at both ends and sides of the frame 1, with their bottoms extending into the openings. Several columns 2 are mounted on the surfaces of the four displacement blocks 3 facing the center of the frame 1. The four displacement blocks 3 move linearly along the openings, applying a clamping force to the part at the top of the frame 1. The columns 2 contact the outer surface of the part, and the workpiece is clamped by displacement. The thrust applied by block 3 causes column 2 to retract into displacement block 3, enclosing the outer surface of the part and ensuring the stability of clamping. A connector 8 is provided in the middle of frame 1, and a motor 12 is provided at the bottom of connector 8. Connector 8 can be driven by motor 12 to rotate, thereby adjusting the angle of the part fixed by frame 1. A base 6 is provided on the outer surface of motor 12, and a slider 16 is provided at the bottom of base 6. A guide rail 15 is installed at the bottom of slider 16, and slider 16 can move linearly on top of guide rail 15, thereby adjusting the angle of part.

[0022] Specifically, the two ends of the frame 1 and the opposite ends of the two side openings are provided with limiting rails 9. The bottom of the displacement block 3 extends into the opening. Both sides of the extension end of the displacement block 3 are provided with slots 10 that match the limiting rails 9. The slots 10 and the limiting rails 9 work together to limit the displacement block 3, so that the displacement block 3 can be driven to make linear movements and apply clamping force to the parts.

[0023] Furthermore, an electric push rod 4 is provided at one end of the displacement block 3 facing the outside of the frame 1. Two uprights 5 are connected between the electric push rod 4 and the outer surface of the frame 1. The fixed end of the electric push rod 4 is fixed by the uprights 5, and the output end of the electric push rod 4 drives the corresponding displacement block 3 to move.

[0024] Furthermore, one end of each of the several columns 2 extends into the interior of the corresponding displacement block 3. Each of the extended ends of the several columns 2 is equipped with a spring 11. When the four displacement blocks 3 move to apply clamping force to the part, the several columns 2 come into contact with the edge of the part. If the part is irregularly shaped, the protrusions on the edge of the part will squeeze the columns 2, causing some of the columns 2 to contract into the displacement block 3, ensuring that the protrusions on the edge of the part are locked and ensuring the tightness of the fixation. The contracted columns 2 squeeze the spring 11. After the part is released, the spring 11 pushes the columns 2, causing the columns 2 to return to their original position.

[0025] Furthermore, a pad 14 is provided on the outer surface of the connector 8 below the frame 1. Four screws 13 are provided on the top of the pad 14. The top of each of the four screws 13 extends through the frame 1. The pad 14 supports the frame 1, and the screws 13 limit the frame 1. After the frame 1 is fitted onto the outside of the screws 13, screws are installed on the extended ends of the screws 13 for reinforcement, so that the frame 1 is fixed tightly. The frame 1 can be disassembled for maintenance.

[0026] Furthermore, a support plate 7 is provided at the bottom of the guide rail 15. The support plate 7 fixes the guide rail 15 in place and can be installed on the machine tool to fix the positioning device in a predetermined position.

[0027] The usage method of this embodiment is as follows: When using the positioning device, the four electric push rods 4 pull the corresponding displacement blocks 3, so that the four displacement blocks 3 are away from the middle position of the frame 1. Then, the part to be clamped is placed on the top of the frame 1, and the four electric push rods 4 drive the displacement blocks 3 to move towards the part position. At this time, several columns 2 are in contact with the outer surface of the part. Through the pushing force applied by the displacement blocks 3, the columns 2 are contracted into the displacement blocks 3, covering the outer surface of the part and ensuring the stability of the clamping. The base 6 in the positioning device is installed on the conveying assembly of the machine tool. The guide rail 15 is perpendicular to the conveying direction of the machine tool. When the irregular part is fixed, it can be moved by the slider 16 at the top of the guide rail 15. At the same time, the connecting piece 8 can drive the frame 1 to rotate, so that the position of the irregular part can be easily adjusted, ensuring that the operating assembly of the machine tool can operate on the predetermined position of the part.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
