[0002] CNC lathe machining is a high-precision automated machining method that controls the displacement of parts and tools through digital information. When machining a workpiece, a CNC machine tool machining standard positioning device can be used to facilitate the positioning of the workpiece.

[0003] The machining standard positioning devices currently available on the market have the following problems in actual use:

[0004] 1. In practice, the traditional CNC machine tool machining standard positioning device requires the use of an external hex wrench to control the locking state of the device. When the external hex wrench is lost, the device will be unusable, which is inconvenient to use.

[0005] 2. In the process of using the machining standard positioning device of most CNC machine tools, since the positioning rod of the device is a separate unit, it can be completely detached from the device. At this time, the positioning rod may be lost. When the positioning rod is lost, the device will lose its positioning effect. Utility Model Content

[0006] The purpose of this utility model is to provide a machining standard positioning device for CNC machine tools to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A machining standard positioning device for a CNC machine tool includes a first base, a T-shaped locking block at the bottom of the first base, a first shaft inside the first base, a bearing sleeved inside the first shaft, a lead screw installed inside the bearing, the lead screw passing through the first base and the T-shaped locking block, a rotating rod installed inside the lead screw, a connecting plate installed on the surface of the first shaft, a second shaft installed inside the connecting plate, a fixing rod welded to the surface of the second shaft, an external thread on the surface of the fixing rod, a second base outside the connecting plate, a mounting seat welded to the top of the second base, a slotted hole inside the mounting seat, a positioning rod sleeved inside the slotted hole, a pressing turntable sleeved on the surface of the fixing rod, one end of the pressing turntable fitting against the top of the mounting seat, and the fixing rod passing through the second base and the mounting seat.

[0008] Preferably, a groove is formed on the surface of the positioning rod, and a sliding rod is provided inside the groove. The sliding rod is located inside the groove hole, and a stop block is welded to both ends of the sliding rod. The surface of the stop block is in contact with the surface of the mounting base.

[0010] Preferably, a slide rail is formed inside the lead screw, the rotating rod is located inside the slide rail, and a retaining rod is welded to the surface of the rotating rod, with the retaining rod located inside the slide rail.

[0011] Preferably, the connecting plates are symmetrically distributed, the lead screw is located between the connecting plates, and the fixing rod is located between the connecting plates.

[0012] Preferably, the first shaft is located outside the T-shaped locking block, and the second shaft is located outside the mounting base.

[0013] The machining standard positioning device for CNC machine tools of this utility model has the following advantages:

[0014] 1. A machining standard positioning device for a CNC machine tool, comprising a T-shaped locking block at the bottom of a first base, a first shaft inside the first base with a bearing sleeved inside the shaft, a lead screw installed inside the bearing, the lead screw passing through the first base and the T-shaped locking block, a rotating rod installed inside the lead screw, a connecting plate installed on the surface of the first shaft, a second shaft installed inside the connecting plate, a fixing rod welded to the surface of the second shaft with external threads, a second base outside the connecting plate, a mounting seat welded to the top of the second base, a slot inside the mounting seat with a positioning rod sleeved inside the slot, and a pressing turntable sleeved on the surface of the fixing rod, one end of the pressing turntable fitting against the top of the mounting seat, and the fixing rod passing through the second base and the mounting seat. When using this device, the T-shaped locking block and the first shaft need to be fixed. When the screw is rotated, it can be rotated directly by rotating the lever. Under the action of the bearing, the screw can be rotated. The contact position between the screw, the first base, and the T-shaped slot is threaded. When the screw rotates, it will drive the T-shaped block to move, thereby fixing the T-shaped block on the machine tool. When the screw rotates, it can provide a squeezing effect between the first shaft and the first base, so that the first shaft and the first base squeeze each other to achieve the fixing effect of the first shaft. When it is necessary to fix the second shaft and the positioning rod, the squeezing turntable can be rotated directly. Under the action of the external thread of the fixing rod, the squeezing turntable can squeeze the mounting seat, thereby increasing the friction between the second shaft and the connecting plate, thereby fixing the second shaft. It also squeezes the internal slot of the mounting seat, so that the slot can fix the positioning rod. At this time, there is no need to use an external hex wrench, which is very convenient to use.

The sliding rod is located inside the groove, and stops are welded to both ends of the sliding rod. The surfaces of the stops are fitted to the surface of the mounting base. When the positioning rod is in use, it can move normally through the groove. As the positioning rod moves, the stops and the sliding rod move synchronously until the stops are located at the end of the groove. The stops provide a limiting effect for the positioning rod, preventing it from dislodging from the groove and ensuring that the positioning rod is not lost. This device is very convenient to use.

[0028] To better understand the purpose, structure, and function of this utility model, the following detailed description of a machining standard positioning device for a CNC machine tool, in conjunction with the accompanying drawings, is provided.

[0029] like Figure 1-5As shown, this utility model discloses a machining standard positioning device for a CNC machine tool, comprising a first base 3, a T-shaped locking block 1 at the bottom of the first base 3, a first shaft 4 inside the first base 3, a bearing 5 sleeved inside the first shaft 4, a lead screw 6 installed inside the bearing 5, the lead screw 6 passing through the first base 3 and the T-shaped locking block 1, a rotating rod 9 installed inside the lead screw 6, and a connecting plate 2 installed on the surface of the first shaft 4. By installing the lead screw 6, when the device needs to fix the T-shaped locking block and the first shaft 4 during use, the lead screw 6 can be rotated directly by the rotating rod 9. Under the action of the bearing 5, the lead screw 6 can rotate. The contact position between the lead screw 6, the first base 3, and the T-shaped locking block is a threaded connection. When the lead screw 6 rotates, it will drive the T-shaped locking block 1 to move, thereby fixing the T-shaped locking block 1 on the machine tool. Furthermore, when the lead screw 6 rotates, it provides a squeezing effect between the first shaft 4 and the first base 3, causing the first shaft 4 and the first base 3 to squeeze against each other, thus achieving the desired positioning of the first shaft 4. The fixing effect is excellent, and it is very convenient to use. A second shaft 10 is installed inside the connecting plate 2. A fixing rod 13 is welded to the surface of the second shaft 10. The surface of the fixing rod 13 is threaded. A second base 11 is provided on the outside of the connecting plate 2. A mounting seat 12 is welded to the top of the second base 11. A slot 16 is opened inside the mounting seat 12. A positioning rod 17 is sleeved inside the slot 16. A pressing turntable 14 is sleeved on the surface of the fixing rod 13. One end of the pressing turntable 14 is attached to the top of the mounting seat 12. The fixing rod 13 passes through the second base 11. With mounting base 12, and by installing extrusion turntable 14, when it is necessary to fix the second shaft 10 and positioning rod 17, the extrusion turntable 14 can be rotated directly. Under the action of the external thread of fixing rod 13, the extrusion turntable 14 can press the mounting base 12, thereby increasing the friction between the second shaft 10 and connecting plate 2, thus fixing the second shaft 10, and extruding the internal slot 16 of mounting base 12, so that the slot 16 can fix the positioning rod 17, which is very convenient to use.

[0030] A groove 20 is formed on the surface of the positioning rod 17, and a sliding rod 19 is provided inside the groove 20. The sliding rod 19 is located inside the slot 16, and a stop block 18 is welded to both ends of the sliding rod 19. The surface of the stop block 18 is attached to the surface of the mounting base 12. By installing the stop block 18 and the sliding rod 19, the positioning rod 17 can be moved normally through the slot 16 when it is in use. When the positioning rod 17 moves, the locking block and the sliding rod 19 will move synchronously until the locking block is located at the end of the groove 20. The locking block can provide a limiting effect for the positioning rod 17, so that the positioning rod 17 will not fall out of the slot 16 and will not be lost. It is very convenient to use.

[0031] A retaining ring 15 is welded to the surface of the fixing rod 13. The extrusion turntable 14 is located between the retaining ring 15 and the mounting base 12. By installing the retaining ring 15, the retaining ring 15 can provide a limiting effect for the extrusion turntable 14, so that the extrusion turntable 14 will not detach from the fixing rod 13, which is very convenient to use.

[0032] A slide rail 7 is opened inside the lead screw 6, and the rotating rod 9 is located inside the slide rail 7. A retaining rod 8 is welded to the surface of the rotating rod 9. The retaining rod 8 is located inside the slide rail 7. By installing the retaining rod 8, the retaining rod 8 can provide a limiting effect for the rotating rod 9, so that the rotating rod 9 will not fall off the lead screw 6, and can provide the rotating rod 9 with the retaining rod 8 as the center, which is very convenient to use.

[0033] The connecting plates 2 are symmetrically distributed, with the lead screw 6 located between the connecting plates 2 and the fixing rod 13 located between the connecting plates 2. The distribution of the connecting plates 2 allows the lead screw 6 and the fixing rod 13 to rotate normally, making it very convenient to use.

[0034] The first shaft 4 is located outside the T-shaped clamp 1, and the second shaft 10 is located outside the mounting base 12. By installing the first shaft 4 and the second shaft 10, the connecting plate 2 can be rotated using the first shaft 4 and the second shaft 10, so that the device can be freely adjusted in angle, which is very convenient to use.

[0035] The working principle of the machining standard positioning device of this CNC machine tool is as follows: When using this device, a T-shaped locking block 1 is provided at the bottom of the first base 3, and a first shaft 4 is provided inside the first base 3. A bearing 5 is sleeved inside the first shaft 4, and a lead screw 6 is installed inside the bearing 5. The lead screw 6 passes through the first base 3 and the T-shaped locking block 1, and a rotating rod 9 is installed inside the lead screw 6. A connecting plate 2 is installed on the surface of the first shaft 4, and a second shaft 10 is installed inside the connecting plate 2. A fixing rod 13 is welded to the surface of the second shaft 10, and the surface of the fixing rod 13 has external threads. A second base 11 is provided outside the connecting plate 2. A mounting base 12 is welded to the top, and a slot 16 is made inside the mounting base 12. A positioning rod 17 is sleeved inside the slot 16, and a pressing turntable 14 is sleeved on the surface of the fixing rod 13. One end of the pressing turntable 14 is attached to the top of the mounting base 12. The fixing rod 13 passes through the second base 11 and the mounting base 12. When the device needs to fix the T-shaped slot and the first shaft 4 during use, the lead screw 6 can be rotated directly by rotating the rotating rod 9. At this time, under the action of the bearing 5, the lead screw 6 can be rotated. The contact position between the lead screw 6, the first base 3, and the T-shaped slot is a threaded connection. When the lead screw 6 rotates, it will drive the T-shaped locking block 1 to move, thereby making the T-shaped locking block 1 move. The type-shaped clamping block 1 can be fixed on the machine tool, and when the lead screw 6 rotates, it can provide a squeezing effect between the first shaft 4 and the first base 3, so that the first shaft 4 and the first base 3 squeeze each other to achieve the fixing effect of the first shaft 4. When it is necessary to fix the second shaft 10 and the positioning rod 17, the squeezing turntable 14 can be rotated directly. Under the action of the external thread of the fixing rod 13, the squeezing turntable 14 can squeeze the mounting seat 12, thereby increasing the friction between the second shaft 10 and the connecting plate 2, thus fixing the second shaft 10, and squeezing the slot 16 inside the mounting seat 12, so that the slot 16 can fix the positioning rod 17. At this time, it is not necessary to use The external hex wrench is very convenient to use. Because a groove 20 is formed on the surface of the positioning rod 17, and a sliding rod 19 is provided inside the groove 20, the sliding rod 19 is located inside the slot 16. Both ends of the sliding rod 19 are welded with stops 18, the surfaces of which are in contact with the surface of the mounting base 12. When using the positioning rod 17, it can be moved normally through the slot 16. As the positioning rod 17 moves, the stops and the sliding rod 19 move synchronously until the stops are located at the end of the groove 20. The stops provide a limiting effect for the positioning rod 17, preventing it from dislodging from the slot 16 and ensuring it is not lost. This makes it very convenient to use.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
