Description

Technical Field

[0001] This utility model relates to the field of milling machine tool technology, and in particular to a right-angle horizontal milling machine tool. Background Technology

[0002] A right-angle horizontal milling machine is a machine tool used for horizontal milling of right-angle workpieces, and has the following structure:

[0003] 1. Bed: It is the basic component of the machine tool, which supports and fixes other components;

[0004] 2. Column: Vertically mounted on the bed, used to support components such as the spindle box, enabling the spindle to move in the vertical direction;

[0005] 3. Worktable: This is the component that carries the workpiece. It is usually mounted on the guide rails of the bed and can realize longitudinal and transverse linear movement.

[0006] 4. Feed system: This includes the feed mechanism for the three coordinate axes X, Y, and Z, and is generally composed of servo motors, ball screws, guide rails, etc.

[0007] 5. Control panel: This is the interface through which the operator interacts with the machine tool's CNC system.

[0008] In right-angle milling, fixtures often employ simple two-point fixing or single-sided clamping methods. Because the right-angle frame has an L-shaped structure, force is applied only to a local area, making it difficult to constrain the entire frame. During machining, the milling force can easily cause the right-angle frame to slide horizontally or twist, resulting in reduced milling accuracy and consequently lower product yield. Furthermore, if a multi-fixture distributed fixing scheme is used with the T-slot of the machine tool table, the installation position of each fixture needs to be adjusted repeatedly to adapt to the clamping requirements of the right-angle frame. This process is cumbersome and time-consuming, disrupting the machining rhythm and reducing overall machining efficiency. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a right-angle horizontal milling machine tool. It solves the problem that in right-angle milling, the fixtures often employ simple two-point fixing or single-sided clamping methods. Because the right-angle frame has an L-shaped structure, force is applied only to a localized area, making it difficult to constrain the entire frame. During machining, the milling force easily causes horizontal slippage or torsion of the right-angle frame, leading to reduced milling accuracy and consequently lower product yield. Furthermore, if a multi-fixture distributed fixing scheme is used with the T-slot of the machine tool's worktable, the installation position of each fixture needs to be repeatedly adjusted to adapt to the clamping requirements of the right-angle frame. This process is cumbersome and time-consuming, disrupting the machining rhythm and reducing overall machining efficiency.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A right-angle horizontal milling machine tool includes a machine tool worktable. A fixing mechanism for fixing the right-angle frame is provided on the outside of the machine tool worktable. The fixing mechanism includes a base, a clamping plate, a through hole, an adjusting rod, and a clamping plate. The base is located outside the machine tool worktable, the end of the clamping plate is located outside the base, the through hole is located outside the base, the adjusting rod is slidably connected inside the through hole, and the clamping plate is fixedly installed on the end of the adjusting rod. A limiting mechanism for fixing the adjusting rod is provided on the side of the base corresponding to the through hole. The limiting mechanism includes a threaded hole and a screw. The threaded hole is located on the side of the base corresponding to the through hole, and the screw is threadedly connected inside the threaded hole.

[0012] Preferably, a support plate for supporting the adjusting rod is slidably connected inside the through hole, and an insertion hole is opened on the inner side of the base corresponding to the through hole. The insertion hole communicates with the inside of the through hole, and the support plate is slidably connected inside the insertion hole. A bolt for fixing the support plate is provided on the inner side of the base corresponding to the insertion hole. A screw hole is opened on the outer side of the machine tool worktable. The screw hole communicates with the inside of the insertion hole, and the bolt is threadedly connected inside the screw hole.

[0013] Preferably, a positioning block is fixedly installed on the outside of the machine tool worktable, and a base is snapped onto the outside of the positioning block. A fixing component for limiting the movement of the base is provided on the outside of the positioning block. The fixing component includes a threaded rod and a nut. The threaded rod is fixedly installed on the outside of the positioning block, and the nut is threadedly connected to the outside of the threaded rod and is used to limit the movement of the positioning block.

[0014] Preferably, the base has a slot on the outside, the end of the clamping plate is engaged in the inside of the slot, the end of the clamping plate is fixedly installed with a screw rod, and the screw rod is threaded with a nut.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The two ends of the right-angle bracket are attached to the two ends of the L-shaped clamping plate. The right-angle surfaces of the L-shaped clamping plate are used to conform to the shape of the right-angle bracket. The clamping plate is pushed so that its two ends are attached to the lower sides of the right-angle bracket. At this time, the clamping plate and the clamping plate form a surrounding clamp, which restricts the horizontal displacement of the right-angle bracket. After the clamping plate is attached to the right-angle bracket and adjusted into place, the first screw is rotated and screwed into the threaded hole of the base, so that the first end of the screw is tightly attached to the surface of the adjusting rod. The position of the adjusting rod is fixed by friction. Compared with the traditional two-point fixing or single-sided clamping mode, the clamping area is increased, the clamping stability is improved, and the horizontal slippage, torsion and elastic deformation of the workpiece during milling are avoided, ensuring the milling accuracy and improving the product qualification rate. At the same time, there is no need to repeatedly adjust the fixture, and the clamping can be completed quickly, improving the processing efficiency. Attached Figure Description

[0023] This application provides a right-angle horizontal milling machine tool, which effectively solves the technical problem that in right-angle milling, the fixtures often adopt simple two-point fixing or single-sided clamping modes. Because the right-angle frame has an L-shaped structure, force is only applied to a local area, making it difficult to form a constraint on the entire right-angle frame. During processing, the milling force is prone to cause horizontal slippage or torsion of the right-angle frame, resulting in reduced milling accuracy and thus reducing the product qualification rate. At the same time, if a multi-fixture distributed fixing scheme is adopted using the T-slot of the machine tool worktable, the installation position of each fixture needs to be adjusted repeatedly to adapt to the clamping requirements of the right-angle frame. The process is cumbersome and time-consuming, thus interfering with the processing rhythm and reducing the overall processing efficiency.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application effectively solves the problem that in right-angle milling, the fixtures often use simple two-point fixing or single-sided clamping modes. Because the right-angle frame has an L-shaped structure, force is only applied to a local area, making it difficult to form a constraint on the entire right-angle frame. During machining, the milling force easily causes the right-angle frame to slide horizontally or twist, resulting in reduced milling accuracy and thus a lower product yield. Furthermore, if a multi-fixture distributed fixing scheme is used with the T-slot of the machine tool table, the installation position of each fixture needs to be repeatedly adjusted to adapt to the clamping requirements of the right-angle frame. This process is cumbersome and time-consuming, thus interfering with the machining rhythm and reducing overall machining efficiency. The overall approach is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a right-angle horizontal milling machine tool, including a machine tool worktable 1. A fixing mechanism for fixing the right-angle frame is provided on the outside of the machine tool worktable 1. The fixing mechanism includes a base 2, a clamping plate 3, a through hole 4, an adjusting rod 5, and a clamping plate 6. The base 2 is located outside the machine tool worktable 1, the end of the clamping plate 3 is located outside the base 2, the through hole 4 is opened outside the base 2, the adjusting rod 5 is slidably connected inside the through hole 4, and the clamping plate 6 is fixedly installed on the end of the adjusting rod 5. The clamping plate 6 is L-shaped, and the clamping plate 3 is composed of an L-shaped plate and cuboid plates at both ends.

[0027] The base 2 serves as the basic support for the fixture, connecting the machine tool worktable 1 with other components and providing a stable installation platform. The clamping plate 3 uses an L-shaped structure to fit the right-angle side of the right-angle frame, providing initial positioning and lateral support, and limiting the horizontal displacement of the workpiece. By sliding the adjusting rod 5 in the through hole 4, the clamping plate 6 can clamp or release the workpiece. The L-shaped clamping plate 6 can press the workpiece from both sides or above to adapt to the needs of different machining surfaces.

[0028] The base 2 is provided with a limiting mechanism for fixing the adjusting rod 5 on the side corresponding to the through hole 4. The limiting mechanism includes a threaded hole 7 and a screw 8. The threaded hole 7 is opened on the side of the base 2 corresponding to the through hole 4. The screw 8 is threadedly connected to the inside of the threaded hole 7. The position of the adjusting rod 5 is locked by the cooperation between the screw 8 and the threaded hole 7. The screw 8 can be rotated to quickly lock and unlock, saving clamping time.

[0029] A support plate 9 for supporting the adjusting rod 5 is slidably connected inside the through hole 4. A socket 10 is opened on the inner side of the base 2 corresponding to the through hole 4. The socket 10 communicates with the inside of the through hole 4. The support plate 9 is slidably connected inside the socket 10. A bolt 11 for fixing the support plate 9 is provided on the inner side of the base 2 corresponding to the socket 10. A screw hole 12 is opened on the outer side of the machine tool worktable 1. The screw hole 12 communicates with the inside of the socket 10. The bolt 11 is threadedly connected inside the screw hole 12. After the adjusting rod 5 moves up, the support plate 9 supports the adjusting rod 5 from below through the socket 10. The bolt 11 fixes the position of the support plate 9 through threaded connection to ensure the stability of the support. The adjustable support height adapts to the needs of different processing positions.

[0030] A positioning block 13 is fixedly installed on the outside of the machine tool worktable 1. The base 2 is snapped onto the outside of the positioning block 13. A fixing component for limiting the movement of the base 2 is provided on the outside of the positioning block 13. The fixing component includes a threaded rod 14 and a nut 15. The threaded rod 14 is fixedly installed on the outside of the positioning block 13. The nut 15 is threadedly connected to the outside of the threaded rod 14 and is used to limit the movement of the positioning block 13. The positioning block 13 provides the installation position of the base 2 and ensures that the fixture is aligned with the reference of the machine tool worktable 1. The base 2 is locked on the positioning block 13 by the threaded fastening between the threaded rod 14 and the nut 15.

[0031] The base 2 has a slot 16 on its outside. The end of the clamping plate 3 is engaged in the inside of the slot 16. The end of the clamping plate 3 is fixedly installed with a screw 17. The screw 17 is threaded with a nut 18. The clamping plate 3 is engaged with the base 2 through the slot 16 and further fixed by the screw 17 and the nut 18. The modular design makes it easy to replace different types of clamping plates 3.

[0032] Working principle:

[0033] First, attach the two ends of the right-angle frame to the two ends of the L-shaped clamping plate 3. Use the right angle surface of the L-shaped clamping plate 3 to fit the shape of the right-angle frame. Push the clamping plate 6 so that the two ends of the clamping plate 6 fit the lower sides of the right-angle frame. At this time, the clamping plate 3 and the clamping plate 6 form a surrounding clamp, which restricts the horizontal displacement of the right-angle frame. After the clamping plate 6 fits the right-angle frame and is adjusted into place, rotate the screw 8 and screw it into the threaded hole 7 of the base 2 so that the end of the screw 8 fits tightly against the surface of the adjusting rod 5. Use friction to fix the position of the adjusting rod 5 and prevent milling vibration from causing the adjusting rod 5 to slide and the clamping force to fail. At this time, the plane where the right-angle frame fits against the machine tool worktable 1 can be horizontally milled.

[0034] The second step is to rotate the screw 8 in the opposite direction to release the lock on the adjusting rod 5. The adjusting rod 5 can slide upward along the through hole 4. At this time, the adjusting rod 5 drives the clamping plate 6 to press on the plane where the right angle frame and the machine tool worktable 1 are in contact. Then, rotate the bolt 11 to move the bolt 11 away from the support plate 9. The support plate 9 moves upward until the end of the support plate 9 is in contact with the lower surface of the adjusting rod 5. Then, rotate the bolt 11 to make the end of the bolt 11 fit tightly against the surface of the support plate 9. At this time, the support plate 9 is fixed. Then, rotate the screw 8 to make the end of the screw 8 and the support plate 9 clamp and fix the adjusting rod 5. At this time, the upper end of the right angle frame is fixed.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
