Description
Technical Field
[0001] This utility model relates to the field of machining center technology, specifically to an adjustment device for milling grooves in a machining center. Background Technology
[0002] A CNC machining center is a type of CNC machine tool with a wide range of functions. It is one of the world's most produced and widely used CNC machine tools. A CNC machining center is a CNC machine tool equipped with a tool magazine and capable of automatic tool changing, which can perform a variety of machining operations on the workpiece within a certain range.
[0003] Milling is a critical process step in drill rod manufacturing, and its quality directly affects whether the drill rod can be properly assembled with the corresponding equipment. The machining center is the main equipment for milling drill rods. In traditional processing, the operator places the drill rod on the V-shaped seat of the machining center's operating table and manually clamps it using a clamping plate. Because the drill rod typically has two symmetrical grooves, it needs to be manually flipped after machining one groove to machine the other. Since this method is entirely manual, it cannot effectively guarantee the stability of the clamping plate during machining or the symmetry of the two grooves after flipping. Therefore, we propose an adjustment device for milling grooves in machining centers. Utility Model Content

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1 to 5 This utility model provides a technical solution: an adjustment device for milling grooves in a machining center, comprising a first mounting plate 1 and a second mounting plate 12, wherein the second mounting plate 12 is located on one side of the first mounting plate 1, as shown below. Figure 6 and Figure 7 As shown, in actual use, the first mounting plate 1 and the second mounting plate 12 can be detachably installed inside the machine tool.
[0024] A movable seat 8 is slidably provided on the first mounting plate 1. The sliding direction of the movable seat 8 is towards the second mounting plate 12. A first guide rail 2 is provided on the top of the first mounting plate 1. There are at least two first guide rails 2. During installation, the first mounting plate 1 is connected to the first guide rail 2 through a slider, so that the movable seat 8 can reciprocate towards the second mounting plate 12.
[0025] A drive unit is mounted on the top of the movable base 8. The drive unit includes a reducer 5 mounted on the movable base 8, and a chuck 4 is mounted on the output end of the drive unit. The output shaft of the reducer 5 is coaxial with the chuck 4. Figure 1 As shown, specifically, the chuck 4 is mounted on the output shaft of the reducer 5, and the axis of the chuck 4 is parallel to the first guide rail 2;
[0026] The side of the movable seat 8 furthest from the second mounting plate 12 is connected to the first telescopic device 7, which is mounted on the first mounting plate 1. This allows the first telescopic device 7 to drive the movable seat 8 to reciprocate along the first guide rail 2 towards the second mounting plate 12, thus moving the chuck 4 closer to or away from the second mounting plate 12. A drive motor 6 is mounted on the input shaft of the reducer 5. When the drive motor 6 rotates, it drives the chuck 4 to rotate. The chuck 4 can be a pneumatic chuck, a two-jaw, three-jaw, or four-jaw chuck, etc. Figure 1 and Figure 2 As shown, the chuck 4 clamps one end of the workpiece 3 (the workpiece 3 is a rod), so when the chuck 4 rotates, it can drive the rod to rotate.
[0027] Furthermore, the second mounting plate 12 is provided with a first fixed support 13, and the top of the first fixed support 13 is rotatably provided with a pin 14 coaxial with the chuck 4, such as... Figure 1 and Figure 2 As shown, the ejector pin 14 is used to hold the end of the workpiece 3 away from the chuck 4. In actual use, the workpiece 3 is placed between the chuck 4 and the ejector pin 14, and the first telescopic device 7 is controlled to move the workpiece 3 to abut against the ejector pin 14 to fix it.
[0028] To better position and support the workpiece 3, a third fixed support 16 is provided on the top of the first mounting plate 1, and a second fixed support 17 is provided on the top of the second mounting plate 12. There is at least one third fixed support 16 and one second fixed support 17. Both the second fixed support 17 and the third fixed support 16 are topped with a sliding plate 18. The top of the sliding plate 18 has a "V"-shaped opening, the height of which matches the height of the chuck 4 and the ejector pin 14. Figure 1 and Figure 2 As shown, when the workpiece 3 is placed between the chuck 4 and the ejector pin 14, the workpiece 3 is first placed inside the top of the slide plate 18. At this time, the workpiece 3 is coaxial with the chuck 4 and the ejector pin 14. This not only makes it convenient to place the workpiece 3, but also makes it convenient to clamp the workpiece 3.
[0029] Based on the above embodiments, in order to fix the workpiece 3, a clamping device is provided on the side of the first fixed support 13 near the driving device, and the workpiece 3 is clamped and fixed by the clamping device.
[0030] like Figure 3 and Figure 4 As shown, the clamping device includes two parallel second guide rails 20 mounted on the top of the second mounting plate 12, with the second guide rails 20 perpendicular to the first guide rail 2. Each end of the first guide rail 2 has a vertically perpendicular strip seat 9. The bottom of each strip seat 9 is connected to the first guide rail 2 via a slide 21, allowing each strip seat 9 to reciprocate along the first guide rail 2. At least one clamping seat 15 is mounted on the top of each strip seat 9. Figure 4 As shown, the clamping seat 15 has a "V"-shaped opening on its side, and the size of the "V"-shaped opening matches the workpiece 3.
[0031] A gear 22 is rotatably provided at the center between the two first guide rails 2 via a support shaft 23. The gear 22 is installed in such a way that the support shaft 23 is fixed on the second mounting plate 12, allowing the gear 22 to be rotatably connected to the support shaft 23, or the support shaft 23 is fixed inside the gear 22, allowing the support shaft 23 to be rotatably connected to the second mounting plate 12. Both installation methods are acceptable.
[0032] The two sides of gear 22 mesh with rack 19, which is parallel to the second guide rail 20. Figure 5 As shown, two racks 19 are staggered, and the ends of the two racks 19 that are far apart from each other are respectively installed below the strip seat 9. A second telescopic device 11 is installed on the side of one of the strip seats 9. The second telescopic device 11 is parallel to the second guide rail 20 and fixed on the second mounting plate 12. When the second telescopic device 11 extends or retracts, it can drive the two strip seats 9 to move closer or further away from the workpiece 3. The strip seats 9 can move stably under the drive of the racks 19, so that the clamping seat 15 clamps the workpiece 3.
[0033] The clamping seat 15 is adjustable, such as... Figure 5 As shown, the top of each strip seat 9 is provided with a T-slot 10 parallel to the second guide rail 20, and the bottom of each clamping seat 15 is mounted on an adjusting seat 24. The adjusting seat 24 is fitted with a rectangular block by fasteners. The rectangular block is placed in the T-slot 10, so that the clamping seat 15 can be adjusted along the T-slot 10.
[0034] Based on the above embodiments, further optimization is possible. Each slide 18 is provided with a vertically downward adjustment groove 25 on its side. The adjustment groove 25 is connected to the third fixed support 16 and the second fixed support 17 respectively by fasteners. This allows each slide 18 to be height-adjustable, which can better support the workpiece 3.
[0035] Based on the above embodiments, it should be further explained that the first telescopic device 7 and the second telescopic device 11 are hydraulic cylinders, electric cylinders or pneumatic cylinders. In this application, the telescopic device is preferably a pneumatic cylinder.
[0036] In summary, the complete working process of the adjustment device proposed in this application is as follows: In the initial state, the chuck 4 is stopped at the end of the first mounting plate 1 away from the second mounting plate 12 and the chuck 4 is in the open state. The workpiece 3 is placed on the slide plate 18. At this time, the first telescopic device 7 can be controlled to drive the chuck 4 to move towards the workpiece 3. When the workpiece 3 contacts the chuck 4, the chuck can clamp the workpiece 3.
[0037] Then, the workpiece 3 is pushed towards the ejector pin 14 and comes into contact with it. Then, the clamping seat 15 can fix the workpiece 3 under the drive of the second telescopic device 11. The machine tool can then process the workpiece 3. When the workpiece needs to be processed on another side, the second telescopic device 11 moves in the opposite direction to drive the clamping seat 15 to retract. Then, the drive motor 6 can drive the workpiece 3 to rotate and then clamp it through the clamping seat 15.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
