Description

TECHNICAL FIELD

[0001] The application belongs to the field of mechanical processing, and relates to a clamping tool for side turning of a part. BACKGROUND

[0002] A lathe is a commonly used metal processing machine tool, mainly used for manufacturing rotary body parts, such as cylinders, cones and circular truncated cones. By rotating the workpiece or the tool, the lathe can perform cutting operations to achieve the predetermined size and surface finish. In order to ensure the stability of the processed parts, various clamps are usually equipped on the lathe, which can firmly fix the parts to be processed on the lathe, while ensuring the exposure of the processing area.

[0003] The traditional shell clamp design is equipped with a positioning boss on the base plate. By fitting the shell into the positioning boss and installing the air cylinder and the pressing plate above the shell, it is ensured that the shell will not move left and right during machining or detection. In order to prevent the shell from rotating, the shell is usually firmly fixed on the base plate by using bolts. However, this clamp relies on manual operation, resulting in low efficiency. Some improved clamps integrate multiple clamping mechanisms above the base plate, which can quickly and firmly clamp the shell from the side, improving operational efficiency. However, for shell parts that need to be machined on the side, the side clamping mechanism becomes an obstacle, hindering the operation of the machining tool. The existing clamps that clamp the parts from the top are large in size, and when the machining equipment is large, the operation becomes inconvenient. CONTENT OF THE INVENTION

[0038] In order to make the technical solutions in the embodiments of the present application clearer, the accompanying drawings needed in the embodiment description will be briefly introduced. Obviously, the accompanying drawings in the following description only constitute some embodiments of the present application, and for those skilled in the art, other drawings can be obtained without creative effort.

[0039] The clamping tool for side surface machining of a part provided by the embodiments of the present application can solve the problems that the existing clamping tool cannot fully expose the side surface machining part and has a large volume.

[0040] As Figure 1 shown in the drawings, the clamping tool for machining the side surface of a part provided by the present application comprises: a base 1, which is provided with a push-pull rod through hole 11; a workbench 2, which is installed on the base 1, and the bench surface 21 is perpendicular to the seat surface 12 of the base 1, and is used to carry the part to be machined 7; a push-pull rod 3, which passes through the push-pull rod through hole 11; a connecting plate 4, one end of which is rotatably connected with the base 1, and the rotation surface formed thereby is perpendicular to the seat surface 12; a pressing rod 5, which is arranged above the workbench 2, has a "Z" shape structure, and is composed of an upper segment 51, a middle segment 52 and a lower segment 53, the middle part of the middle segment 52 is rotatably connected with the other end of the connecting plate 4 along the rotation surface, and the end of the lower segment 53 is connected with one end of the push-pull rod 3 which faces the workbench 2; and a pressing plate 6, which is connected below the end of the upper segment 51, and is used to apply pressure to the top surface of the part to be machined 7.

[0041] The principle of the clamping tool for machining the side surface of a part provided by the present application is as follows:

[0042] In the present application, the pressing rod 5 plays the role of a lever, and the fulcrum thereof is located at the connecting point of the middle segment 52 and the connecting plate 4. When the push-pull rod 3 is pushed forward to the direction of the workbench 2, it will push the end of the lower segment 53 of the pressing rod 5, and by means of the principle of lever, the end of the upper segment 51 connected with the pressing plate 6 will be lifted upward, resulting in the separation of the pressing plate 6 from the part to be machined 7; on the contrary, when the push-pull rod 3 is pulled backward, away from the direction of the workbench 2, it will pull the end of the lower segment 53 of the pressing rod 5 backward, and by means of the principle of lever, the end of the upper segment 51 connected with the pressing plate 6 will be lowered, so that the pressing plate 6 is in contact with the part to be machined 7. By further increasing the pulling force of the push-pull rod 3, the pressure between the pressing plate 6 and the part to be machined 7 can be enhanced, so as to ensure that the part to be machined 7 is firmly clamped between the pressing plate 6 and the workbench 2.

[0043] In some embodiments of the present application, the base 1 is provided with a connecting plate seat 41, one end of the connecting plate 4 is connected with the connecting plate seat 41 through a pin shaft, and the other end is connected with the middle part of the middle segment 52 through a pin shaft. The connecting plate seat 41, the connecting plate 4, the pressing rod 5 and the push-pull rod 3 are arranged on the same plane, so that the connecting plate 4, the pressing rod 5 and the push-pull rod 3 can move on the plane. In more detail, the upper segment 51 of the pressing rod 5 is a straight line rod which is parallel to the bench surface 21; the lower segment 53 is also a straight line rod, and when the push-pull rod 3 moves forward or backward, it will drive the lower segment 53 to move linearly along the axial direction of the push-pull rod 3. The middle segment 52 is an inclined rod, the connecting plate seat 41 is installed on the seat surface 12 directly above the push-pull rod through hole 11, and the two ends of the connecting plate 4 are connected with the middle segment 52 and the connecting plate seat 41 respectively through pin shafts, so as to convert the horizontal linear motion of the lower segment 53 into the up-down translation motion of the upper segment 51.

[0044] In some embodiments of the present application, the machined part 7 is a shell type part, and the clamping force needs to be accurately controlled during machining to prevent excessive clamping force from damaging the shell type part.

[0045] In some embodiments of the present application, the end of the lathe spindle is provided with an adapter disc 9, and the base 1 is installed on the adapter disc 9. Since the lathe spindle is a standard workpiece, the base 1 cannot be directly connected with it, and the present application adds an adapter disc for transition between the lathe spindle and the base 1. The adapter disc 9 is fixedly connected with the lathe spindle and the base 1, preferably by bolts. The base 1 is arranged at the end of the lathe spindle, so that the clamping tool of the present application can be flexibly adjusted in angle to adapt to the machining requirements of various complex parts, which greatly improves the machining flexibility and efficiency of the lathe.

[0046] In some embodiments of the present application, the lathe rotating oil cylinder pull rod 8 is arranged in the lathe spindle, and the lathe rotating oil cylinder pull rod 8 is connected with the end of the push-pull rod 3 opposite to the workbench 2. The lathe rotating oil cylinder pull rod 8 provides power for the push-pull rod 3 to realize the functions of pushing forward or pulling backward. When the lathe rotating oil cylinder pull rod 8 is extended, the push-pull rod 3 pushes forward to the direction of the workbench 2, prompting the pressing plate 6 to separate from the machined part 7; when the telescopic rod is retracted, the push-pull rod 3 pulls the pressing plate 6, so that the pressing plate 6 tightly presses the machined part 7. Through the use of the lathe rotating oil cylinder pull rod 8, the clamping tool of the present application can realize quick clamping and releasing during part machining, which significantly improves the machining efficiency. In addition, the use of the lathe rotating oil cylinder pull rod 8 reduces the complexity of manual operation and reduces the labor intensity, so that the whole machining process is more automated and intelligent.

[0047] In some embodiments of the present application, the clamping tool of the present application further comprises a sensor for monitoring the contact force between the pressing plate 6 and the machined part 7. The sensor is arranged on the pressing plate 6 and can real-time feedback pressure data. When the pressure data exceeds the safe range, the extension length of the lathe rotating oil cylinder pull rod 8 can be adjusted to adjust the pressure applied by the pressing plate 6 on the part to the preset safe range, so as to prevent damage to the part due to excessive pressure.

[0048] In some embodiments of the present application, the base 1 is disc-shaped, and the rotating shaft of the lathe rotating oil cylinder pull rod 8 passes through the center of the base 1 and is perpendicular to the seat surface 12.

[0049] In some embodiments of the present application, the bottom surface and the top surface of the machined part 7 are parallel, and the table surface 21 is parallel to the bottom surface of the pressing plate 6. This design ensures that the machined part 7 can be uniformly pressed during machining, avoiding machining errors caused by displacement or inclination of the machined part 7.

[0050] In some embodiments of the present application, positioning grooves are provided on the table 21, which are used to engage the bottom surface of the machined part 7. This design ensures the accurate positioning of the machined part 7 during machining. The design of the positioning grooves matches the shape of the bottom surface of the machined part 7, so that the machined part 7 can be quickly and accurately placed in the designated position when the lathe spindle is operated. This design not only improves the positioning accuracy of the machined part 7, but also reduces the need for manual intervention, further improving the level of automation.

[0051] In some embodiments of the present application, at least two positioning pins are provided on the table 21. The function of these positioning pins is to block the machined part 7, ensuring its accurate position during machining. Specifically, the table 21 is provided with a plurality of preformed positioning holes, and the positioning pins can be detached and installed in these positioning holes. When it is necessary to replace different types of machined parts 7, the positioning pins can be reinstalled to accurately position the new machined part 7.

[0052] In some embodiments of the present application, the pressing rod 5 is an integral structure, which has good rigidity and strength and can withstand the force and torque during machining. The integral structure design reduces the assembly steps, simplifies the production process, and reduces the cost. In actual application, the stable performance of the pressing rod 5 effectively prevents vibration during machining, ensuring the surface quality of the part side machining.

[0053] As shown in Figure 4 In some embodiments of the present application, the pressing rod 5 and the pressing plate 6 are connected through a universal ball head. This design allows the pressing plate 6 to rotate in all directions, ensuring that the lower plane of the pressing plate 6 can completely fit the compressed surface of the workpiece, producing a better compression effect.

[0054] In the description of the present application, it should be noted that the orientation or position relationship indicated by the terms "upper", "lower", etc. is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. Unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be broadly understood, for example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0055] It should be noted that, in the present application, the relational terms such as "first" and "second", and the like, are used solely to distinguish one entity or action from another, without necessarily requiring or implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.
