[0002] The turret is a turret used for CNC machine tools, and is mainly used to load various types of tools such as turning, milling, and drilling. CN116809988B discloses a power turret, including a cutter disc and a turret shell, wherein the turret shell is arranged at the rear end of the cutter disc; a first drive assembly is arranged inside the cutter disc, and a second drive assembly is arranged outside the cutter disc, wherein the second drive assembly includes a second drive motor and a planetary reducer, wherein the planetary reducer matches the output shaft of the second drive motor, and the planetary reducer is fixedly connected to the turret shell; a central shaft is arranged at the rear end face of the cutter disc, and a positioning assembly is arranged on the outer sleeve of the central shaft, and the positioning assembly matches the planetary reducer; a connecting shaft is arranged inside the central shaft, and the connecting shaft matches the first drive assembly, and a positioning sleeve is arranged at one end of the connecting shaft away from the first drive assembly, and the end of the central shaft away from the cutter disc is connected to the end face of the positioning sleeve.

[0003] The power turret of the above structure is equipped with a second drive assembly to generate power to drive the central axis to rotate. For this power turret, since the second drive motor is configured at the rear of the cutter head, it cannot be connected to the main shaft of the machine tool. When it is installed on the ram of the machine tool, a special mounting seat is required to fix it with the ram. Therefore, the existing power turret needs to be equipped with a separate drive on the one hand, and is relatively locked when loading and unloading with the machine tool ram on the other hand. Utility Model Content

[0004] The utility model provides a novel turret, which can be directly connected with a power output mechanism of a machine tool, and utilizes a main shaft on the machine tool as a power source for cutting, so that assembly and disassembly are simple and rapid.

[0005] The technical solutions to the above technical problems are as follows:

[0006] A novel turret comprises a rotating shaft assembly, a housing, a tool disc for installing a tool, a first locking and combining component, a second locking and combining component, and a first driving assembly. The rotating shaft assembly is rotatably mounted on the housing, the first locking and combining component is fixed to the tool disc, the second locking and combining component is fixed to the housing, the second locking and combining component is arranged relative to the first locking and combining component, the tool disc is fixed to the first driving assembly, the first driving assembly cooperates with the rotating shaft assembly and drives the tool disc to move axially along the rotating shaft assembly after obtaining power, so that the first locking and combining component is combined or separated from the second locking and combining component, the first driving assembly is fixed to the rotating shaft assembly in the circumferential direction, or the first driving assembly is combined or separated from the rotating shaft assembly in the circumferential direction after moving along the axial direction of the rotating shaft assembly; it also comprises a transmission assembly connected to a main shaft on a machine tool, the transmission assembly is assembled in the housing, and the transmission assembly cooperates with the rotating shaft assembly; the housing has a coupling surface for directly combining with the machine tool, and a connecting component for connecting with the machine tool is fixed on the housing.

[0007] The above scheme is adopted, and the box body has a coupling surface for direct coupling with the machine tool. The coupling surface, for example, cooperates with the ram on the machine tool. Different models of rams may have different shapes. Therefore, the shape of the coupling surface is configured according to the shape of the machine ram, so that there is no need to use other clamping tools to connect the machine tool and the turret. The machine tool is connected to the connecting component, for example, by applying tension to the connecting component by tightening the oil cylinder, so that the coupling surface on the box body can be directly matched with the ram. In addition, the main shaft installed on the ram is connected to the transmission component. The utility model uses the main shaft on the machine tool as the power source for cutting, so that loading and unloading are simple and rapid. In addition, the new turret in the utility model does not need to adopt a separate oil supply or air supply system, and directly uses the hydraulic system on the machine tool to supply oil to control the position of the first drive component so that the cutter disc is in a locked or released state. This not only simplifies the structure of the new turret, but also reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figures 1 to 11 The new turret of the utility model includes a rotating shaft assembly 1, a box body 2, a tool disc 3 for installing a tool, a first locking and combining component 4, a second locking and combining component 5, a first driving assembly, and a transmission assembly. Each part and the relationship between them are described in detail below.

[0024] The rotating shaft assembly 1 is rotatably mounted on the housing 2. The housing 2 is provided with a first shaft hole 1b and a second shaft hole 1c. The axial directions of the first shaft hole 1b and the second shaft hole 1c are perpendicular. In this embodiment, the axial direction of the first shaft hole 1b is parallel to the horizontal direction, and the axial direction of the second shaft hole 1c is parallel to the vertical direction. The rotating shaft assembly 1 includes a rotating shaft 1d and a supporting bearing 1e. The supporting bearing 1e is mounted in the first shaft hole 1b, and the rotating shaft 1d passes through the supporting bearing 1e.

[0025] The first locking and combining component 4 is fixed to the cutter disc 3, and the second locking and combining component 5 is fixed to the housing 2, and the second locking and combining component 5 is arranged opposite to the first locking and combining component 4. The first locking and combining component 4 and the second locking and combining component 5 are preferably toothed discs, and the axial end surface of the toothed disc is provided with combining teeth. When the first locking and combining component 4 is meshed with the combining teeth on the second locking and combining component 5, the cutter disc 3 cannot rotate.

[0026] The cutter disc 3 is fixed to the first drive assembly, which cooperates with the rotating shaft assembly 1 and drives the cutter disc 3 to move along the axial direction of the rotating shaft assembly 1 after obtaining power, so that the first locking and combining component 4 is combined or separated from the second locking and combining component 5, and the first drive assembly is fixed to the rotating shaft assembly 1 in the circumferential direction, or the first drive assembly moves along the axial direction of the rotating shaft assembly 1 and then combines or separates from the rotating shaft assembly 1 in the circumferential direction;

[0027] When the first locking combination component 4 is meshed with the combining teeth on the second locking combination component 5, the circumferential freedom of the first locking combination component 4 and the second locking combination component 5 is locked, and the cutter disc 3 is fixed to the first locking combination component 4. In this way, the circumferential freedom of the cutter disc 3 is also locked, so that the cutter disc 3 cannot rotate. When the first locking combination component 4 is separated from the second locking combination component 5, the circumferential freedom of the first locking combination component 4 is not restricted, and the shaft assembly 1 can drive the cutter disc 3 to rotate.

[0028] The box body 2 has a coupling surface 2a for directly coupling with the machine tool. The coupling surface 2a cooperates with the slide on the machine tool, for example. Different models of slides may have different shapes. Therefore, the shape of the coupling surface 2a is configured according to the shape of the machine slide, so there is no need to use additional clamping tools to connect the machine tool and the turret.

[0029] A first step hole 2c is provided at one end of the box body 2, and the first drive component is arranged in the first step hole 2c. A first flow channel 2d and a second flow channel 2e for conveying a fluid medium are provided on the box body 2. The openings at one end of the first flow channel 2d and the second flow channel 2e are located on the step in the first step hole 2c. The fluid medium can be liquid or gas. In the utility model, hydraulic oil is preferably used as the fluid medium. When the new turret is connected to the slide on the machine tool, the new turret cooperates with the hydraulic system on the slide, and the output end of the first flow channel 2d is connected to the first step hole 2c, and the output end of the second flow channel 2e cooperates with the first drive component.

[0030] Therefore, the new turret in the utility model does not need to adopt a separate oil supply or air supply system, and directly uses the hydraulic system on the machine tool (the slide is part of the machine tool) to supply oil to control the position of the first drive assembly. This not only simplifies the structure of the new turret, but also reduces costs.

[0031] The first driving assembly includes a fixed component and a movable component. The first step hole 2c includes a first hole 2c1 and a second hole 2c2. A first step 2c3 is provided between the first hole 2c1 and the second hole 2c2. The fixed component is located in the first hole 2c1 and is fixed to the box body 2.

[0032] The fixed component includes a disk-shaped component 6 and a cylindrical component 7. The disk-shaped component 6 is provided with a first through hole 6a. The disk-shaped component 6 is fixed to one end of the cylindrical component 7. After the other end of the cylindrical component 7 is combined with the first step 2c3, a receiving cavity 2c4 is formed between the fixed component and the first step 2c3. The middle part of the movable component is located in the receiving cavity 2c4 and matches with the inner circumference of the cylindrical component 7. One end of the movable component is located outside the receiving cavity 2c4 and matches with the inner circumference of the second hole 2c2. The other end of the movable component passes through the first through hole 6a.

[0033] The movable part includes a piston 8, a first connecting part 9, and a second connecting part 10. The piston 8 is located in the accommodating cavity 2c4 and cooperates with the inner circumference of the cylindrical part 7. The accommodating cavity is divided into a left cavity and a right cavity (from the left to the right) by the piston 8. Figure 2 or Figure 6 The first flow channel 2d cooperates with the left cavity, a drainage channel 7a is provided on the fixed component, one end of the drainage channel 7a cooperates with the second flow channel 2e, and the other end of the drainage channel 7a cooperates with the right cavity. A first annular groove is provided on the circumference of the piston 8, and a first sealing ring 8a is installed in the first annular groove. The first sealing ring 8a cooperates with the inner wall surface of the tubular component 7 to form a seal on both sides of the piston 8.

[0034] The first connecting component 9 and the second connecting component 10 are respectively located on both sides of the piston 8. The first connecting component 9 is fixed to the piston 8 and / or the second connecting component 10. The first connecting component 9 is preferably formed integrally with the piston 8. In this embodiment, an assembly hole 8b is provided on the piston 8. One end of the second connecting component 10 is inserted into the assembly hole 8b. The first connecting component 10 is connected to the second connecting component 10 by passing through the first connecting component 9, so that the piston 8 is fastened to the first connecting component 9 and the second connecting component 10 as a whole. A second annular groove is provided on the hole wall of the assembly hole 8b. A second sealing ring 8c is installed in the second annular groove. The gap between the second connecting component 10 and the piston 8 is sealed by the second sealing ring 8c.

[0035] The first connecting component 9 is sleeved on the rotating shaft assembly 1, and the first connecting component 9 is fixed to the rotating shaft assembly 1 in the circumferential direction, or the first driving assembly moves along the axial direction of the rotating shaft assembly 1 and then combines or separates from the rotating shaft assembly 1 in the circumferential direction. A spline sleeve is provided in the inner hole of the first connecting component 9, and a spline is provided on the circumferential surface of the rotating shaft assembly 1, and the first connecting component 9 and the rotating shaft assembly 1 are matched through the spline.

[0036] In this embodiment, the preferred structure of the first connecting component 9 and the rotating shaft assembly 1 in the circumferential direction is: a key 1a is fixed on the circumferential surface of the rotating shaft assembly 1, and a keyway is set on the rotating shaft 1d. After the key 1a is fitted in the keyway, the key 1a and the rotating shaft 1d are fixed by screws. The key 1a is L-shaped, and a part of the key 1a protrudes out of the circumferential surface of the rotating shaft 1d. An annular component 9a is provided on the inner hole wall of the first connecting component 9, and a groove 9b is provided on the annular component 9a. After the first driving component moves along the axial direction of the rotating shaft assembly 1, the groove 9b is combined with or separated from the key 1a.

[0037] The second connecting component 10 is loosely sleeved on the rotating shaft assembly 1 , and the second connecting component 10 passes through the first through hole 6 a . The second connecting component 10 is fixed to the cutter disc 3 .

[0038] When the hydraulic oil flows into the left cavity through the first flow channel 2d, the hydraulic oil pushes the piston 8 to move from left to right, and the first connecting component 9 and the second connecting component 10 follow the piston 8 to move from left to right. The key 1a is combined with the groove 9b, so that the shaft assembly 1 and the first connecting component 9 are fixed in the circumferential direction. At the same time, the second connecting component 10 drives the cutter disc 3 to move from left to right, so that the first locking combination component 4 is separated from the second locking combination component 5. At this time, if the transmission assembly obtains torque, the transmission assembly will transmit the torque to the shaft assembly 1, and the shaft assembly 1 can drive the movable parts and the cutter disc 3 to rotate.

[0039] When the hydraulic oil flows into the right cavity through the second flow channel 2e and the drainage channel 7a, the hydraulic oil pushes the piston 8 to move from right to left, and the first connecting component 9 and the second connecting component 10 follow the piston 8 to move from right to right, and the key 1a is separated from the groove 9b, releasing the circumferential fixation of the rotating shaft assembly 1 and the first connecting component 9. At the same time, the second connecting component 10 drives the cutter disc 3 to move from right to left, so that the first locking combination component 4 is combined with the second locking combination component 5. At this time, even if the transmission assembly obtains torque, since the first connecting component 9 is not connected to the rotating shaft assembly 1 in the circumferential direction, the cutter disc 3 cannot rotate. In addition, due to the action of the hydraulic oil, the first locking combination component 4 and the second locking combination component 5 form a locking relationship, thereby putting the cutter disc 3 in a locked state.

[0040] The transmission assembly is connected to the main shaft of the machine tool, and the transmission assembly is assembled in the box 2, and the transmission assembly cooperates with the rotating shaft assembly 1; a connecting component 2b for connecting with the machine tool is fixed on the box 2. The connecting component 2b preferably adopts a rivet, and a tensioning cylinder is installed on the ram of the machine tool. After the tensioning cylinder is connected to the connecting component 2b, the tensioning cylinder applies a pulling force to the connecting component 2b, and the ram has a matching part with the joint surface 2a, so that the new turret as a whole is tightly combined with the ram.

[0041] The transmission assembly includes an outer fixed sleeve, a bearing assembly 20, an inner transmission assembly, and a telescopic locking assembly that allows the inner transmission assembly and the outer fixed sleeve to be combined or separated in the circumferential direction. A second step hole 2f is provided on the housing 2, and the outer fixed sleeve is arranged in the second step hole 2f. The outer fixed sleeve includes a fixed sleeve 24 and a connecting ring 25. The bearing assembly 20 is installed in the fixed sleeve 24 of the outer fixed sleeve, and the fixed sleeve 24 is inserted into the second step hole 2f. The fixed sleeve 24 passes through the second step hole 2f and cooperates with the second axial hole 1c. One end of the fixed sleeve 24 is provided with a first connecting flange 24a, and the other end of the fixed sleeve 24 is provided with a limiting ring 24b located in the inner hole of the fixed sleeve 24. The limiting ring 24b forms a limit for the bearing assembly 20. One end of the fixed sleeve 24 is fixed to the second step 2g in the second step hole 2f, that is, the fixed sleeve 24 is fixed to the second step 2g through the first connecting flange 24a.

[0042] The connecting ring 25 is fixed to the fixing sleeve 24, and the connecting ring 25 is preferably fixed on the first connecting flange 24a. Since the bearing assembly 20 is installed in the outer fixing sleeve, the outer fixing sleeve is circumferentially provided with a first locking portion 21 for cooperating with the inner transmission assembly. In order to avoid interference between the first locking portion 21 and the bearing assembly 20, a radial protrusion 26 is provided on the connecting ring 25. The first locking portion 21 is arranged on the radial protrusion 26, and the radial protrusion 26 extends toward the inner transmission assembly, so that the radial protrusion 26 is located above the bearing assembly 20. The radial protrusion 26 is annular or arc-shaped. In this embodiment, the radial protrusion 26 is an arc-shaped block, and there is a gap between two adjacent arc-shaped radial protrusions 26, and the gap is the first locking portion 21.

[0043] The inner transmission assembly passes through the bearing assembly 20 and is fixed to the bearing assembly 20, and one end of the inner transmission assembly is combined with the shaft assembly 1; the telescopic locking assembly and the inner transmission assembly are axially slidably matched, and the telescopic locking assembly and the inner transmission assembly are circumferentially fixed.

[0044] The inner transmission assembly includes a hollow shaft 30, a first bevel gear 31, and a second bevel gear 32. The hollow shaft 30 passes through the bearing assembly 20. The hollow shaft 30 and the bearing assembly 20 are interference fit. The telescopic locking assembly and the inner wall of the hollow shaft 30 are key-fitted so that the telescopic locking assembly can slide axially along the inner transmission assembly. For example, the telescopic locking assembly and the hollow shaft 30 are spline-fitted, or a first keyway 30a is provided on the inner wall of the hollow shaft 30, and the first keyway 30a extends along the axial direction of the hollow shaft 30. A flat key is fixed on the outer wall surface of the telescopic locking assembly, and the flat key cooperates with the first keyway 30a, so that the telescopic locking assembly and the hollow shaft 30 are circumferentially fixed, and the telescopic locking assembly can slide relative to the hollow shaft 30.

[0045] The first bevel gear 31 is fixed to the hollow shaft 30 , the first bevel gear 31 is meshed with the second bevel gear 32 , the second bevel gear 32 is fixed to the rotating shaft assembly 1 , and the second bevel gear 32 is fixed to the rotating shaft 1 d .

[0046] The telescopic locking assembly is provided with a second locking portion 22, and the second locking portion 22 is combined with the first locking portion 21 to lock the degree of freedom of the inner transmission assembly in the circumferential direction. In this way, even if the transmission assembly obtains torque from the machine tool spindle, the telescopic locking assembly cannot be rotated due to the combination of the second locking portion 22 and the first locking portion 21, and the telescopic locking assembly cannot drive the hollow shaft 30 to rotate. It can be seen that the telescopic locking assembly and the first locking portion 21 and the second locking portion 22 are provided, and after the turret stops working, the transmission assembly of the turret can be locked to prevent the shaft assembly 1 and the turret from rotating, thereby improving the safety of the product.

[0047] The telescopic locking assembly includes a transmission shaft 40, a first flange 41, a second flange 42, and a spring 43. One end of the transmission shaft 40 is fixed to the first flange 41. The second locking portion 22 is installed on the circumferential surface of one end of the transmission shaft 40. The first flange 41 is provided with a coupling portion 41a for coupling with the power output end of the machine tool. The coupling portion 41a is a coupling groove provided on the first flange 41. The second flange 42 is fixed to the inner transmission assembly. A countersunk hole is provided on the first bevel gear 31. The second flange 42 is located in the countersunk hole. Screws are used to pass through the second flange 42 and fixed to the hollow shaft 30, so that the second flange 42 and the inner transmission assembly are fastened together.

[0048] The other end of the transmission shaft 40 is provided with a mounting hole 41b, one end of the spring 43 is matched with the mounting hole 41b, and the other end of the spring 43 is matched with the second flange 42. The telescopic locking assembly also includes a guide rod 44, the spring 43 is sleeved on the guide rod 44, one end of the guide rod 44 is matched with a hole gap set in the second flange 42, and the other end of the guide rod 44 is matched with the transmission shaft 40.

[0049] The telescopic locking assembly also includes an auxiliary rivet assembly 45, one end of which is fixed to the transmission shaft 40, and the other end of which is used to connect to a tensioning component installed on the machine tool, such as a tension spring, so as to increase the stability of the connection between the new turret and the machine tool.

[0050] When the transmission assembly needs to be operated, the main shaft (the main shaft and the ram are rotationally matched, and the main shaft is not shown in the figure) on the machine tool moves downward, the main shaft is sleeved on the auxiliary rivet assembly 45, and the main shaft is inserted into the joint 41a, so that the main shaft and the first flange 41 are circumferentially fixed, and the main shaft applies downward pressure to the first flange 41, so that the transmission shaft 40 moves downward, and the transmission shaft 40 applies pressure to the spring 43, so that the spring 43 is compressed between the transmission shaft 40 and the second flange 42. After the transmission shaft 40 moves downward, the second locking part 22 moves downward, and the second locking part 22 and the first locking part 21 are switched from the combined state to the separated state. At this time, if the first locking combination component 4 and the second locking combination component 5 are separated, the main shaft outputs torque, and the main shaft drives the transmission shaft 40 to rotate. The torque is transmitted to the cutter head 3 after passing through the transmission shaft 40, the hollow shaft 30, the first bevel gear 31, the second bevel gear 32, the first connecting component 9, and the second connecting component 10 in sequence, so that the cutter head 3 rotates.

[0051] When the main shaft stops working, it moves upward for a distance, the main shaft releases the pressure applied by the first flange 41, the spring 43 releases the tension, the spring 43 pushes the transmission shaft 40 to move upward, the second locking part 22 moves upward with the main shaft 40, and the second locking part 22 and the first locking part 21 are switched from a separated state to a combined state. At this time, even if a torque is applied to the first flange 41, the first flange 41 cannot be rotated.

[0052] What is disclosed above is only a preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present utility model. Ordinary technicians in this field can understand that all or part of the structures of the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the application.
