Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to an adjustable Swiss-type lathe tooling and fixture. Background Technology

[0002] A Swiss-type lathe, also known as a Swiss-type CNC lathe, works by rotating its C-axis and moving it along the Z-axis, while the tool post operates in conjunction with the Z / X / Y axes to machine the workpiece. The tooling fixtures for a Swiss-type lathe are devices used to fix and hold the workpiece during machining. They play a crucial role in ensuring machining accuracy, improving production efficiency, and ensuring operational safety.

[0003] CN222242663U discloses a stepped chuck for a Swiss-type headstock machining center, relating to the field of chuck technology. The chuck includes a chuck with a cavity at its front end. A sleeve is disposed inside the cavity, and a gasket is placed at the bottom of the cavity. A spring is laterally fixed to the tail end of the sleeve, and the tail end of the spring is fixedly connected to the upper surface of the gasket. This invention, by installing a sleeve inside the stepped chuck, allows it to adapt to designs with bars of different diameters, increasing its versatility and meeting the needs of various Swiss-type headstock machining centers. It reduces compatibility issues when changing chucks, improves processing efficiency and quality, and enhances the stability of the chuck by adding a sleeve, reducing the possibility of wear and loosening during use and ensuring the stability of processing accuracy.

[0004] While the existing technology CN222242663U has many advantages in use, it still has the following problems: the reliability of workpiece insertion is not perfect. Because the end of the workpiece is inserted into the inside of the clamp, it is not easy for the operator to accurately understand the insertion depth of the workpiece, which will affect the clamping stability between the workpiece and the clamp. Utility Model Content

[0005] In view of the problems in the prior art, this utility model provides an adjustable Swiss-type machine tooling fixture.

[0006] The technical solution adopted by this utility model to solve its technical problem is an adjustable Swiss-type machine tooling fixture, including a chuck column, a slide groove and a base plate. A sleeve is provided inside the chuck column, and a base plate is provided on the inner wall of the chuck column away from the sleeve. A slide groove distributed in a circular array is opened on the inner wall of the chuck column, and a slider is slidably installed inside the slide groove. A movable part is provided on one side of the outer wall of the slider.

[0007] By adopting the above technical solution, the design of the slide groove allows the slider and moving parts to slide inside it, which can ensure the stability of the horizontal movement trajectory of the clamp inside the chuck column. Through the cooperation of the chuck column and the clamp, the end of the workpiece inside the clamp can be clamped and fixed, ensuring the positional stability of the workpiece inside the clamp.

[0008] Specifically, a mounting base is welded to the outer wall of one end of the clamping column, and a through hole is opened on one side of the outer wall of the mounting base.

[0009] By adopting the above technical solution, the chuck column is installed on the Swiss-type lathe via the mounting base. The through-hole design makes the installation process simpler and faster, while also providing a stable mounting foundation, ensuring the stability and accuracy of the equipment during operation.

[0010] Specifically, both the clamping column and the outer wall of the clamping sleeve are provided with a circular array of clamping cavities, and a waist-shaped groove is provided on one side of the inner wall of the clamping cavity.

[0011] By adopting the above technical solution, the clamping cavity increases the clamping area of ​​the fixture and improves the clamping force. The design of the waist-shaped groove also allows for a certain degree of fine adjustment of the clamping force, thereby better adapting to changes in the shape and size of the workpiece and ensuring machining accuracy.

[0012] Specifically, a screw hole is provided on one side of the inner wall of the chuck cylinder, and the base plate is threaded into the screw hole.

[0013] By adopting the above technical solution, the base plate ensures its stable position in the chuck column through the screw holes, and the size of the base plate is smaller than the inner diameter of the inner wall of the chuck column, so it will not affect the normal use of the chuck column, and ensures that the base plate can be easily disassembled and maintained.

[0014] Specifically, a spring is provided on one side of the outer wall of the base plate, and a push plate is provided on the other end of the spring, which is in contact with the outer wall of the jacket.

[0015] By adopting the above technical solution, the spring force pushes the push plate, ensuring that the use position of the push plate and the clamp is controlled. The operator manually picks up the end of the workpiece and inserts it between the clamps, making it contact with the push plate. Then, the operator pushes the workpiece, causing the push plate to retract into the inside of the chuck column until the push plate contacts the base plate. At this time, by rotating the movable part, the movable part is brought into a horizontal state, so that the inner wall of the clamp is in contact with the outer wall of the movable part, ensuring that the clamps hold the workpiece stably and firmly. After the workpiece is pulled out, the spring force can push out the push plate and the clamp.

[0016] Specifically, a limit rod is welded to one side of the outer wall of the slider, and the movable part is rotatably mounted on the outside of the limit rod.

[0017] By adopting the above technical solution, the limiting rod ensures the stable sliding and rotation of the moving part outside the slide groove, thereby adjusting the usage angle after the clamp extends out of the chuck column.

[0018] Specifically, the movable part is located outside the sleeve, and a connector is provided inside the movable part, and the sleeve is connected to the movable part through the connector.

[0019] By adopting the above technical solution, the connector achieves a tight connection between the moving part and the clamp. This design not only improves the overall strength, but also allows the moving part to be adjusted according to the shape and size of the workpiece during the clamping process, ensuring that the inner circle curvature of the clamp is adapted to the size of the workpiece, thereby improving the adaptability and machining accuracy of the clamp.

[0020] The beneficial effects of this utility model are:

[0021] (1) The adjustable Swiss-type lathe tooling fixture described in this utility model allows the movable parts to be changed according to the shape and size of the workpiece during the clamping process, ensuring that the inner circle curvature of the clamp is adapted to the size of the workpiece, thereby improving the adaptability and machining accuracy of the clamp.

[0022] (2) The adjustable Swiss-type machine tooling fixture described in this utility model can make the clamps in the unfolded state when not in use, so that when the workpiece is inserted between the clamps and in contact with the push plate, the operator can clearly know the distance between the workpiece and the clamps, ensuring that the clamps hold the workpiece stably and firmly.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the adjustable Swiss-type machine tooling fixture of this utility model includes a chuck column 1, a slide groove 2, and a base plate 3. A sleeve 22 is provided inside the chuck column 1. The base plate 3 is provided on the inner wall of the chuck column 1 away from the sleeve 22. The inner wall of the chuck column 1 has a slide groove 2 distributed in a circular array. A slider 21 is slidably installed inside the slide groove 2. A movable part 23 is provided on one side of the outer wall of the slider 21.

[0032] In use, the design of the slide groove 2 allows the slider 21 and the movable part 23 to slide inside it, which can ensure the stability of the horizontal movement trajectory of the clamp 22 inside the chuck column 1. Through the cooperation of the chuck column 1 and the clamp 22, the end of the workpiece inside the clamp 22 can be clamped and fixed, ensuring the positional stability of the workpiece inside the clamp 22.

[0033] To secure the clamping column 1, for example, as shown... Figure 1 As shown, a mounting base 12 is welded to the outer wall of one end of the clamp column 1, and a through hole is opened on one side of the outer wall of the mounting base 12.

[0034] In use, the chuck column 1 is mounted onto the Swiss-type lathe via the mounting base 12. The through-hole design makes the installation process simpler and faster, while also providing a stable mounting base to ensure the stability and accuracy of the equipment during operation.

[0035] For the range of deformation, exemplified, such as Figure 2 As shown, both the chuck column 1 and the sleeve 22 have circular arrayed cavities 11 on their outer walls, and a waist-shaped groove is formed on one side of the inner wall of the cavity 11.

[0036] When in use, the clamping cavity 11 increases the clamping area of ​​the fixture and improves the clamping force. The waist-shaped groove design also allows for a certain degree of fine adjustment of the clamping force, thereby better adapting to changes in the shape and size of the workpiece and ensuring machining accuracy.

[0037] To fix the usage location, for example, such as Figure 2 As shown, a screw hole 13 is provided on one side of the inner wall of the chuck column 1, and the base plate 3 is threaded into the screw hole 13.

[0038] During use, the base plate 3 ensures that it is stably positioned in the chuck column 1 through the screw hole 13, and the size of the base plate 3 is smaller than the inner diameter of the inner wall of the chuck column 1, so it will not affect the normal use of the chuck column 1, and ensures that the base plate 3 can be easily disassembled and maintained.

[0039] To drive movement, for example, such as Figure 3 As shown, a spring 31 is provided on one side of the outer wall of the base plate 3, and a push plate 32 is provided on the other end of the spring 31. The push plate 32 is in contact with the outer wall of the sleeve 22.

[0040] During use, the spring 31 pushes the push plate 32 to ensure that the positions of the push plate 32 and the clamp 22 are controlled. The operator manually picks up the end of the workpiece and inserts it into the clamp 22 until it contacts the push plate 32. Then, the operator pushes the workpiece so that the push plate 32 retracts into the chuck column 1 until the push plate 32 contacts the base plate 3. At this time, the movable part 23 is rotated to make it horizontal, so that the inner wall of the clamp 22 contacts the outer wall of the movable part 23, ensuring that the clamp 22 holds the workpiece stably and firmly. After the workpiece is pulled out, the spring 31 can push out the push plate 32 and the clamp 22.

[0041] To limit the rotation angle, for example, such as Figure 5 As shown, a limit rod 25 is welded to one side of the outer wall of the slider 21, and the movable part 23 is rotatably mounted on the outside of the limit rod 25.

[0042] During use, the limiting rod 25 ensures the stable sliding and rotation of the movable part 23 outside the slide groove 2, thereby allowing adjustment of the operating angle of the sleeve 22 after it extends out of the chuck column 1.

[0043] To facilitate the replacement of the sleeve 22, for example, such as Figure 5 As shown, the movable part 23 is located outside the sleeve 22, and a connector 24 is provided inside the movable part 23. The sleeve 22 is connected to the movable part 23 through the connector 24.

[0044] In use, the connector 24 achieves a tight connection between the movable part 23 and the clamp 22. This design not only improves the overall strength, but also allows the movable part 23 to be adjusted according to the shape and size of the workpiece during the clamping process, ensuring that the inner circle curvature of the clamp 22 is adapted to the size of the workpiece, thereby improving the adaptability and machining accuracy of the clamp 22.

[0045] When using this utility model, the chuck column 1 is installed at the designated position of the Swiss-type machine through the mounting base 12 and through hole at one end, ensuring that the mounting base 12 is aligned with the interface of the Swiss-type machine. The operator takes the chuck 22 that conforms to the workpiece size and installs it on the outside of the movable part 23 through the connector 24.

[0046] The operator manually inserts the end of the workpiece to be processed into the chuck 22. At this time, the workpiece will come into contact with the push plate 32. The operator continues to push the workpiece, so that the push plate 32 is subjected to pressure and retracts into the chuck column 1 until the push plate 32 comes into contact with the base plate 3. At this time, the workpiece has been initially positioned. As the chuck 22 enters and follows into the chuck column 1, it can rotate through the limit rod 25 and the movable part 23, so that the chuck 22 changes the use angle and the chuck 22 covers the outer wall of the workpiece.

[0047] After the sleeve 22 is fully inserted into the body, the front end of the sleeve 22 retracts, thereby clamping the workpiece with the sleeve 22.

[0048] It should be noted that this utility model is an adjustable tooling fixture for Swiss-type lathes. All components in this utility model are known to those skilled in the art, and their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
