Description
Technical Field
[0001] This utility model relates to the field of chamfering tooling technology, and in particular to a chamfering tooling adjustment device for lathe machining. Background Technology
[0002] A chamfering fixture for lathe machining is a tool or device specifically designed for chamfering on a lathe. Chamfering refers to machining an angled surface at the edge or corner of a material to improve safety, quality, and assembly performance. A chamfering fixture typically includes: 1. A workpiece clamp: used to fix the workpiece and ensure its stability during machining; 2. A chamfering tool: selected according to the machining requirements to perform the chamfering process.
[0003] Publication No. CN 222537003 U discloses a pneumatic, one-time automatic chamfering fixture with a clamp head, and Publication No. CN218503879 U discloses a chamfering fixture for a forging die for automotive forgings. Both of these chamfering fixtures can only clamp round or square workpieces and cannot be adjusted according to whether the workpiece is round or square, resulting in poor applicability. Furthermore, when chamfering a workpiece, both sides need to be chamfered. However, when using these existing chamfering fixtures, after one side of the workpiece is chamfered, it cannot be automatically flipped over. The workpiece must be released, flipped over, and then clamped and fixed before the other side can be chamfered, which is very cumbersome. Utility Model Content

The technical problem to be solved is that existing chamfering fixtures can only clamp round or square workpieces, and cannot be adjusted according to whether the workpiece is round or square, resulting in poor applicability. Furthermore, when chamfering a workpiece, both sides need to be chamfered. However, when using existing chamfering fixtures, after one side of the workpiece is chamfered, it cannot be automatically flipped over. The workpiece needs to be released, flipped over, and then clamped and fixed before the other side of the workpiece can be chamfered, which is very troublesome.
[0006] (II) Technical Solution
[0007] To achieve the above technical objectives, this utility model provides a chamfering fixture adjustment device for lathe machining:
[0008] It includes two vertical plates, with a horizontal plate fixed between them. A first hydraulic cylinder is mounted on the horizontal plate, and a support plate is fixed to the extended end of the first hydraulic cylinder. A rotating rod is rotatably connected to the top of each of the two vertical plates. A cylindrical tube is slidably connected to the outer side of the rotating rod. A hollow rectangular clamping plate is fixed to the end of the cylindrical tube away from the rotating rod. Two rectangular blocks are slidably connected inside the hollow rectangular clamping plate. The upper and lower sides of the rectangular blocks are in contact with the inner walls of the upper and lower sides of the hollow rectangular clamping plate. A groove is formed inside the rectangular block, and a bracket is rotatably connected to the groove. A protruding post is fixed to one end of the bracket, and a hemisphere is fixed to the end of the protruding post away from the bracket. An adjustment component for adjusting the position of the protruding post is provided inside the hollow rectangular clamping plate, and a fixing component for fixing the bracket after rotation is provided on the rectangular block.
[0009] Preferably, the adjustment assembly includes a bidirectional screw that rotates within a hollow rectangular clamping plate. The bidirectional screw passes through two rectangular blocks and is threadedly connected to the rectangular blocks. The two rectangular blocks are located on different threaded sections of the bidirectional screw. A rectangular groove is provided on one side of the hollow rectangular clamping plate, and the bracket is slidably fitted within the rectangular groove.
[0010] Preferably, the fixing component includes a first magnetic strip fixed to the inner wall of the groove, a second magnetic strip fixed on the bracket, the first and second magnetic strips having opposite magnetic poles, and two storage slots provided on the hollow rectangular clamp, the bracket and the protrusion being able to rotate into the storage slots.
[0011] Preferably, an annular plate is rotatably connected to the outer side of the cylindrical tube, a connecting plate is fixed to the outer side of the annular plate, a movable plate is fixed to the bottom of the connecting plate, a first guide rod is fixed between the two vertical plates, the first guide rod passes through the movable plate, the movable plate is slidably fitted to the outside of the first guide rod, a second hydraulic cylinder is installed on the inner wall of the vertical plate, and the extended end of the second hydraulic cylinder is fixed to the movable plate.
[0012] Preferably, the cylindrical tube has multiple stroke grooves inside, and multiple limiting blocks are fixed on the outside of the rotating rod, with the limiting blocks slidingly engaged in the corresponding stroke grooves.
[0013] Preferably, one of the vertical plates has two side plates fixed on one side, and two second guide rods are fixed between the two side plates. A toothed plate is provided between the two side plates, and the second guide rods pass through the toothed plate. The toothed plate is slidably engaged with the second guide rods.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:
[0015] 1. When clamping a square workpiece, rotate the bidirectional screw to move the two rectangular blocks away from each other. When the groove in the rectangular block protrudes from the receiving slot, rotate the bracket and protrusion 90 degrees, causing the first and second magnetic strips to attract each other. At this time, the bracket and protrusion are in a vertical position and located in the receiving slot. The hollow rectangular clamp can then clamp the square workpiece. When clamping a round workpiece, rotate the protrusion and bracket to move them out of the receiving slot, causing the first and second magnetic strips to separate. Then rotate the bidirectional screw to move the two rectangular blocks closer together. As the rectangular blocks move, they move the bracket, causing it to move into the rectangular groove. At this time, the rectangular groove acts as a limit, preventing the bracket from rotating further. This allows the four hemispheres to clamp the round workpiece. By rotating the bidirectional screw to adjust the position of the protrusion and hemispheres, round workpieces of different diameters can be clamped and fixed. In other words, the device can be adjusted accordingly as needed.
[0016] 2: When the chamfering of one side of the workpiece is completed, and the other side of the workpiece needs to be chamfered, the third hydraulic cylinder is activated to drive the toothed plate to move. When the toothed plate moves, it drives the gear to rotate. When the gear rotates, it drives the rotating rod, the cylindrical tube, and the hollow rectangular clamping plate to rotate, so that the workpiece can be flipped over, making it convenient to chamfer both sides of the workpiece.

[0023] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.
[0024] Reference Figure 1-4 :
[0025] In one embodiment of this utility model, a chamfering fixture adjustment device for lathe machining is provided, comprising two vertical plates 1, a horizontal plate 2 fixed between the two vertical plates 1, a first hydraulic cylinder 3 mounted on the horizontal plate 2, a support plate 4 fixed to the extended end of the first hydraulic cylinder 3, a rotating rod 5 rotatably connected to the top of each of the two vertical plates 1, a cylindrical tube 6 slidably connected to the outside of the rotating rod 5, a hollow rectangular clamping plate 7 fixed to the end of the cylindrical tube 6 away from the rotating rod 5, two rectangular blocks 8 slidably connected inside the hollow rectangular clamping plate 7, the upper and lower sides of the rectangular blocks 8 being in contact with the inner walls of the upper and lower sides of the hollow rectangular clamping plate 7, a groove 9 being provided inside the rectangular blocks 8, a bracket 10 rotatably connected inside the groove 9, a protruding post 11 fixed to one end of the bracket 10, a hemisphere 12 fixed to the end of the protruding post 11 away from the bracket 10, an adjustment component for adjusting the position of the protruding post 11 being provided inside the hollow rectangular clamping plate 7, and a fixing component for fixing the bracket 10 after rotation being provided on the rectangular blocks 8.
[0026] The adjustment assembly includes a bidirectional screw 26 that rotates within the hollow rectangular clamp 7. The bidirectional screw 26 passes through two rectangular blocks 8 and is threadedly connected to the rectangular blocks 8. The two rectangular blocks 8 are located on different threaded sections of the bidirectional screw 26. A rectangular groove 30 is provided on one side of the hollow rectangular clamp 7, and the bracket 10 slides within the rectangular groove 30. Furthermore, the fixing assembly includes a first magnetic strip 28 fixed to the inner wall of the groove 9, and a second magnetic strip 29 fixed to the bracket 10. The first magnetic strip 28 and the second magnetic strip 29 have opposite magnetic poles. The hollow rectangular clamp 7... Two storage slots 31 are provided on the top. The bracket 10 and the protruding column 11 can rotate into the storage slots 31. Furthermore, an annular plate 13 is rotatably connected to the outside of the cylindrical tube 6. A connecting plate 14 is fixed to the outside of the annular plate 13. A movable plate 15 is fixed to the bottom of the connecting plate 14. A first guide rod 16 is fixed between the two vertical plates 1. The first guide rod 16 passes through the movable plate 15. The movable plate 15 is slidably fitted to the outside of the first guide rod 16. A second hydraulic cylinder 17 is installed on the inner wall of the vertical plate 1. The extended end of the second hydraulic cylinder 17 is fixed to the movable plate 15.
[0027] In use, the first hydraulic cylinder 3 first extends, causing the support plate 4 to move upwards until it is below the hollow rectangular clamping plate 7. Then, the workpiece is placed on the support plate 4. Next, the second hydraulic cylinder 17 is activated, causing the moving plate 15 to move. When the moving plate 15 moves, it moves the connecting plate 14, the annular plate 13, and the cylindrical cylinder 6. When the cylindrical cylinder 6 moves, it moves the hollow rectangular clamping plate 7, allowing the hollow rectangular clamping plate 7 to clamp the square workpiece. If the workpiece is circular, by rotating the protruding post 11 and the bracket 10, the bracket 10 and the protruding post 11 are rotated out of the receiving groove 31, causing the first magnetic strip 28 and the second magnetic strip 29 to separate. Then, rotate the bidirectional screw 26 to drive the two rectangular blocks 8 closer together. When the rectangular blocks 8 move, they drive the bracket 10, the protrusion 11, and the hemisphere 12 to move, so that the bracket 10 moves into the rectangular groove 30. At this time, the rectangular groove 30 acts as a limit, so that the bracket 10 can no longer rotate, that is, the position of the bracket 10 is fixed. When the two hollow rectangular clamping plates 7 are close to each other, the four hemispheres 12 can clamp the circular workpiece. By rotating the bidirectional screw 26, the position of the protrusion 11 and the hemisphere 12 can be adjusted, so that circular workpieces of different diameters can be clamped and fixed, which makes it convenient for the chamfering tool to chamfer the workpiece.
[0028] It should be noted that when a square workpiece needs to be clamped, the bidirectional screw 26 is rotated to move the two rectangular blocks 8 away from each other. When the groove 9 in the rectangular block 8 is exposed from the storage groove 31, the bracket 10 and the protrusion 11 are rotated 90 degrees, so that the first magnetic strip 28 and the second magnetic strip 29 are attracted together. At this time, the bracket 10 and the protrusion 11 are in a vertical state and located in the storage groove 31. At this time, the hollow rectangular clamping plate 7 can clamp the square workpiece.
[0029] In addition, multiple stroke grooves 25 are provided inside the cylindrical tube 6, and multiple limiting blocks 24 are fixed on the outside of the rotating rod 5. The limiting blocks 24 are slidably engaged in the corresponding stroke grooves 25. Two side plates 18 are fixed on one side of one of the vertical plates 1. Two second guide rods 19 are fixed between the two side plates 18. A toothed plate 20 is provided between the two side plates 18. The second guide rods 19 pass through the toothed plate 20. The toothed plate 20 is slidably engaged with the outside of the second guide rods 19. A gear 23 is fixed at the end of one of the rotating rods 5 that extends outside the vertical plate 1. The toothed plate 20 and the gear 23 mesh with each other. A base plate 21 is fixed at the bottom of the toothed plate 20. A third hydraulic cylinder 22 is installed on one of the side plates 18. The extended end of the third hydraulic cylinder 22 is fixed to the base plate 21.
[0030] When in use, after one side of the workpiece is chamfered, if the other side of the workpiece needs to be chamfered, the third hydraulic cylinder 22 is activated to move the toothed plate 20. When the toothed plate 20 moves, it drives the gear 23 to rotate. When the gear 23 rotates, it drives the rotating rod 5, the cylindrical tube 6, and the hollow rectangular clamping plate 7 to rotate, thereby automatically flipping the workpiece over, making it convenient to chamfer both sides of the workpiece.
[0031] It should be noted that the first hydraulic cylinder 3, the second hydraulic cylinder 17, and the third hydraulic cylinder 22 in this embodiment are all commercially available conventional equipment known to those skilled in the art. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. They will not be described in detail here. Furthermore, the first hydraulic cylinder 3, the second hydraulic cylinder 17, and the third hydraulic cylinder 22 are all equipped with matching control switches. The installation position of the control switches can be selected according to actual usage requirements to facilitate operation and control by the operator.
[0032] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
