Description

Technical Field

[0001] This invention relates to the field of turning machine tool technology, and in particular to a CNC turning machine tool with intelligent anti-offset positioning for motor housing. Background Technology

[0002] As a key component of the powertrain in new energy vehicles, the machining accuracy of the motor housing's bearing holes and stop surfaces directly affects the motor's assembly quality and operational stability. The outer wall of the motor housing features mounting bases for connection to the vehicle frame and cooling fins, making it a typical asymmetrical structural part.

[0003] In CNC turning, when the limit sleeve drives the motor housing to rotate at high speed, the mass distribution in the area where the mounting base is located is uneven, and the center of mass deviates from the center of rotation, generating an eccentric centrifugal force whose direction changes periodically with the rotation of the spindle. This eccentric centrifugal force is transmitted to the spindle bearings and tool post system, causing forced vibration of the machine tool, resulting in tool vibration during turning. This leaves vibration marks on the inner wall and end face of the motor housing, causing the bearing hole roundness to exceed tolerances and the surface roughness value to increase. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and to propose an intelligent anti-offset CNC turning machine tool for motor housing positioning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A CNC turning machine tool for intelligent anti-deviation positioning of motor housing includes: a turning machine, and a limiting component disposed on the turning machine for fixing the motor housing. The limiting component includes a limiting cylinder rotatably disposed on the turning machine, and a slot opened on the limiting cylinder corresponding to the motor housing mounting seat. The limiting cylinder is provided with an adjustment component for stabilizing its rotation. The adjustment component includes two sliders that are slidably disposed on the limiting cylinder, and a counterweight ball is provided on the slider on the side away from the slot. When the limiting cylinder rotates, the slider moves radially according to the rotational vibration of the limiting cylinder.

[0006] Preferably, the limiting assembly further includes a tray fixedly disposed inside the limiting cylinder, with multiple grippers hinged to the outer side of the tray, and a hydraulic rod for driving the grippers to rotate is disposed at the bottom of the limiting cylinder.

[0007] Preferably, the adjusting assembly further includes a lead screw rotatably disposed at the bottom of the limiting cylinder, the slider being threadedly connected to the lead screw, and a bevel gear being disposed on the lead screw, a drive motor being disposed at the bottom of the limiting cylinder, and the output end of the drive motor being meshed with the bevel gear, the top of the slider being wedge-shaped, and a counterweight ball being fixed to the lower side of one of the sliders, and an acceleration sensor being disposed at the bottom of the limiting cylinder.

[0008] Preferably, the limiting cylinder is provided with a support component for limiting the movement of the motor housing during machining, and when the slider moves, the support component extends to limit the movement of the motor housing.

[0009] Preferably, the support assembly includes a plurality of support rods that are slidably disposed at equal angles within the limiting cylinder, a first spring is sleeved on the support rod, and an arc-shaped plate that fits against the motor housing is provided at the end of the support rod, and a transmission part is provided between the support rod and the slider.

[0010] Preferably, the transmission unit includes a plurality of wedge-shaped extrusion blocks slidably disposed within the limiting cylinder. The extrusion blocks are in contact with the ends of the support rods. A connecting frame is fixedly disposed between the plurality of extrusion blocks, and a second spring is fixedly disposed at the bottom of the connecting frame. The bottom of the extrusion blocks is wedge-shaped, and the extrusion blocks are in contact with the top of the slider.

[0011] Preferably, the limiting cylinder is provided with a cooling component for cooling the motor housing during machining, and the spray flow rate of the cooling component is adjusted when the support rod slides.

[0012] Preferably, the cooling assembly includes multiple spray holes inclinedly opened on the tray, and the multiple spray holes are located inside the motor housing. The support rod has a cavity inside, and the cavity communicates with the spray holes. A liquid storage tank is provided on the upper part of the limiting cylinder, and a sealing ring is slidably provided on the top of the liquid storage tank. The liquid storage tank communicates with the cavity.

[0013] Preferably, an adjusting plate is slidably disposed inside the cavity. Both the adjusting plate and the support rod are provided with through holes. A connecting rod is fixedly disposed at one end of the adjusting plate, and the connecting rod is fixedly disposed on the limiting cylinder.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The vibration of the limiting cylinder is detected by an accelerometer. The PLC controls the drive motor to move the lead screw, which in turn drives the slider and counterweight ball. This causes the centrifugal force generated by the counterweight ball to cancel out the eccentric centrifugal force of the motor housing mounting base, achieving automatic centrifugal force balance during the rotation of the limiting cylinder. This avoids the offset vibration phenomenon during motor housing machining, improving machining accuracy. Simultaneously, the slider movement, linked to the pressing block, pushes the support rod radially outward, causing the support force of the arc plate on the outer wall of the motor housing to change synchronously with the rotational speed of the limiting cylinder. This results in greater support force at higher speeds, preventing tool deflection during high-speed machining and enhancing the rigidity of the motor housing during machining. The internal adjusting plate aligns with the through hole of the support rod when the support rod extends, and the area of ​​the alignment changes synchronously with the position of the support rod. This allows the coolant flow rate of the spray nozzle to adaptively adjust with the rotation speed of the limiting cylinder. This achieves the effect of reducing the spray volume at high speeds to prevent coolant splashing and waste, and increasing the spray volume at low speeds to ensure sufficient cooling. This realizes the supply of coolant on demand. Furthermore, the coolant is sprayed upwards from the bottom surface inside the motor housing, and the centrifugal force generated by the rotation of the motor housing causes the coolant to form a uniform liquid film on the inner wall. This achieves the effect of the coolant precisely acting on the cutting area without splashing and waste, thus improving cooling efficiency and reducing coolant consumption.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0021] In the description of this specification, the references to terms such as "embodiment," "one embodiment," "some implementations," "exemplary," and "one implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0022] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0023] Combination Figures 1-10 This invention provides an intelligent anti-offset CNC turning machine tool for positioning motor housing, including: a turning machine 1, and a limiting component 2 disposed on the turning machine 1 for fixing the motor housing. The limiting component 2 includes a limiting cylinder 21 rotatably disposed on the turning machine 1, and a slot 24 opened on the limiting cylinder 21 corresponding to the motor housing mounting seat. The limiting cylinder 21 is provided with an adjustment component 3 for stabilizing its rotation. The adjustment component 3 includes two sliders 31 slidably disposed within the limiting cylinder 21, and a counterweight ball 33 is provided on the slider 31 on the side away from the slot 24. When the limiting cylinder 21 rotates, the slider 31 moves radially according to the rotational vibration of the limiting cylinder 21; Reference Figure 1 , Figure 2 as well as Figure 10 The motor housing is placed inside the limiting cylinder 21. Since the motor housing is generally cast, the mounting base and the housing are an integral structure. Therefore, when the motor housing is placed inside the limiting cylinder 21, the mounting base is positioned in the slot 24, and the limiting cylinder 21 forms a limit. Subsequently, the limiting cylinder 21 is driven to rotate by an external motor. When the limiting cylinder 21 rotates, the turning tool on the turning machine 1 descends to turn the motor housing. Because the motor housing has a mounting base, the rotation during turning is not a linear circular rotation. The weight of the mounting base causes centrifugal force to cause eccentricity when the motor housing rotates. Therefore, when the motor housing rotates, the slider 31 on the limiting cylinder 21 moves. Since one of the sliders 31 is equipped with a counterweight ball 33, the movement of the slider 31 drives the counterweight ball. 33 moves away from the motor housing mounting base; that is, when the slider 31 drives the counterweight ball 33 to a certain position, the counterweight ball 33 and the motor mounting base form symmetry, which can ensure the stability of the motor housing during rotation, avoid insufficient accuracy of the motor housing during turning due to centrifugal force, realize automatic compensation of centrifugal force, and ensure the turning effect of the motor housing; the formula for calculating centrifugal force is mass multiplied by the square of angular velocity and then multiplied by radius. When the position of the motor housing mounting base is fixed, the counterweight ball 33 and the motor housing mounting base have the same rotational angular velocity and both rotate through the limit cylinder 21. Therefore, it is only necessary to set a constant mass of counterweight ball 33 and change its position to make the centrifugal force the same, thereby avoiding the occurrence of tool vibration during turning and reducing the vibration of the motor housing.

[0024] Preferred, Reference Figure 4 and Figure 6The limiting assembly 2 also includes a tray 22 fixedly installed inside the limiting cylinder 21. Multiple grippers 23 are hinged to the outside of the tray 22. A hydraulic rod for driving the grippers 23 to rotate is provided at the bottom of the limiting cylinder 21. The grippers 23 are hinged to the limiting cylinder 21 via a rotating shaft. The bottom of the multiple grippers 23 is provided with a hydraulic rod. When the hydraulic rod extends, the grippers 23 rotate via the rotating shaft, so that the multiple grippers 23 limit the motor housing from the bottom. With the use of the slot 24, the stability of the turning rotation is ensured and the shaking during the turning process is avoided. A drain port is opened in the center of the tray 22, and a hose is provided at the bottom of the drain port. The hose extends to the outside of the bottom of the limiting cylinder 21 to facilitate the discharge and collection of waste chips and waste liquid.

[0025] Preferred, Reference Figure 7 The adjusting assembly 3 also includes a lead screw 32 rotatably mounted at the bottom of the limiting cylinder 21. A slider 31 is threaded onto the lead screw 32, and a bevel gear is mounted on the lead screw 32. A drive motor is mounted at the bottom of the limiting cylinder 21, and the output end of the drive motor meshes with the bevel gear. The top of the slider 31 is wedge-shaped, and a counterweight ball 33 is fixed to the underside of one of the sliders 31. An acceleration sensor 34 is mounted at the bottom of the limiting cylinder 21. The acceleration sensor 34 can measure the vibration of the limiting cylinder 21 during rotation. Specifically, when the slider 31 is initially close to the center of the limiting cylinder 21, centrifugal force will be generated due to the motor housing mounting base when the limiting cylinder 21 rotates. Vibration occurs when the accelerometer 34 detects the vibration of the limit cylinder 21 during rotation. The PLC controller then controls the drive motor to rotate the lead screw 32. As the lead screw 32 rotates, the two sliders 31 connected to the screw 32 move simultaneously, and the counterweight ball 33 moves away from the motor housing mounting seat, making them gradually symmetrical. Alternatively, the counterweight ball 33 can be lightweight but move a suitable distance, thus achieving centrifugal force balance and ensuring the stability of the limit cylinder 21 during rotation. The position of the slider 31 is adaptively adjusted by the drive motor, allowing centrifugal force compensation to be performed when turning different motor housings, further improving the ease of use of the equipment and reducing the steps of fixture replacement.

[0026] Preferred, Reference Figure 7 The limiting cylinder 21 is provided with a support component 4 for limiting the motor housing during turning. When the slider 31 moves, the support component 4 extends to limit the motor housing. When the limiting cylinder 21 rotates, the upper side of the motor housing is not limited by the gripper 23 and has weak rigidity, which may cause the tool to deflect. Therefore, when the limiting cylinder 21 rotates, the support component 4 extends to limit the motor housing.

[0027] Preferred, Reference Figure 7The support assembly 4 includes multiple support rods 41 that are slidably disposed within the limiting cylinder 21 at equal angles. A first spring 42 is sleeved on each support rod 41, and an arc-shaped plate 43 that fits against the motor housing is provided at the end of each support rod 41. A transmission part is provided between the support rod 41 and the slider 31. When the slider 31 moves, it indicates that the rotation speed of the limiting cylinder 21 gradually increases. At this time, the slider 31 pushes the transmission part, which in turn pushes the support rod 41 to gradually extend, so that the end of the support rod 41 gradually contacts the surface of the motor housing. That is, the greater the centrifugal force, the faster the rotation speed of the limiting cylinder 21. The faster the rotation speed of the limiting cylinder 21, the tighter the support rod 41 fits against the surface of the motor housing, thereby effectively limiting the surface of the motor housing, preventing tool deflection during turning, increasing the rigidity of the motor housing surface, and further ensuring the turning effect and stability. When the rotation speed of the limiting cylinder 21 decreases, the elastic force of the first spring 42 will pull the support rod 41 to gradually return to its original position, realizing the effect of adjusting the support rod 41 according to the change in the rotation speed of the limiting cylinder 21.

[0028] Preferred, Reference Figure 7 The transmission unit includes multiple wedge-shaped extrusion blocks 44 slidably disposed within the limiting cylinder 21. The extrusion blocks 44 are attached to the ends of the support rod 41. A connecting frame 46 is fixedly disposed between the multiple extrusion blocks 44, and a second spring 45 is fixedly disposed at the bottom of the connecting frame 46. The bottom of the extrusion blocks 44 is wedge-shaped, and the extrusion blocks 44 are attached to the top of the slider 31. When the slider 31 moves, since the top of the slider 31 and the bottom of the connecting frame 46 are wedge-shaped, the slider 31 will gradually push the connecting frame 46 to drive the extrusion blocks 44 to move upward. When the extrusion blocks 44 move upward, since the extrusion blocks 44 are wedge-shaped, they will push the support rod 41 to move, so that the support rod 41 can fully limit the upper side of the motor housing, ensuring the stability of the motor housing during cutting and preventing the tool from deflecting during cutting.

[0029] Preferred, Reference Figure 6 , Figure 7 , Figure 8 and Figure 9 The limiting cylinder 21 is equipped with a cooling component 5 for cooling the motor housing during machining, and the spray flow rate of the cooling component 5 is adjusted when the support rod 41 slides. Since the rotation speed of the limiting cylinder 21 is not constant during the machining of the motor housing, and if the coolant spray is always constant, it will lead to coolant waste. Therefore, when the rotation speed of the limiting cylinder 21 changes, the coolant spray of the cooling component 5 changes at the same time to adapt to heat dissipation.

[0030] Preferred, Reference Figure 6 , Figure 7 , Figure 8 and Figure 9The cooling assembly 5 includes multiple spray holes 51 inclinedly formed on the tray 22, with the spray holes 51 located inside the motor housing. A cavity is formed inside the support rod 41, communicating with the spray holes 51. A liquid storage tank 55 is provided on the limiting cylinder 21, and a sealing ring is slidably provided on the top of the liquid storage tank 55. The liquid storage tank 55 communicates with the cavity. Since the spray holes 51 are formed on the tray 22, when the motor housing is placed on the tray 22, the spray holes 51 are located inside the motor housing. That is, when liquid from the liquid storage tank 55 enters the tray 22... When the coolant is sprayed out from the spray nozzle 51, it sprays upward from the bottom of the motor housing. Since the motor housing is rotating, the centrifugal force of the rotating motor housing causes the sprayed coolant to adhere to the inner wall surface of the motor housing, i.e., the cutting position. This effectively prevents the coolant from splashing and wasting. At the same time, it can fully form a coolant film on the inner wall of the motor housing, so that the coolant is always at the contact position between the cutting tool and the motor housing during turning, ensuring the cutting effect, preventing coolant waste, and avoiding overheating during cutting that could damage the cutting tool.

[0031] Preferred, Reference Figure 6 , Figure 7 , Figure 8 and Figure 9 An adjusting plate 52 is slidably disposed within the cavity. Both the adjusting plate 52 and the support rod 41 have through holes 53. A connecting rod 54 is fixedly disposed at one end of the adjusting plate 52, and the connecting rod 54 is fixedly disposed on the limiting cylinder 21. Because the rotational speed of the limiting cylinder 21 is not constant, and the centrifugal force of the motor housing is also unstable, the slider 31 needs to be repeatedly adjusted. Each adjustment of the slider 31 causes the support rod 41 to slide, i.e., the rotational speed of the limiting cylinder 21 changes. When the support rod 41 slides, the adjusting plate 52 slides... The connecting rod 54 is fixed to the support rod 41. Therefore, when the support rod 41 is close to the motor housing, it indicates that the rotation speed is high. At this time, the gap of the through hole 53 becomes smaller, resulting in less liquid being sprayed. This prevents the water film from forming too thickly on the inner wall of the motor housing, which would affect heat dissipation. It also prevents liquid from being thrown out and wasted when the rotation speed is high. When the rotation speed of the limiting cylinder 21 decreases, the coolant can fully act on the inner wall of the motor housing. At this time, the gap of the through hole 53 becomes larger, which not only improves the heat dissipation effect but also avoids the waste of coolant.

[0032] Working principle The motor housing is placed into the limiting cylinder 21, so that the mounting seat of the motor housing is engaged in the slot 24 on the limiting cylinder 21, achieving initial circumferential limiting; the hydraulic rod extends to push the gripper 23 to rotate around the rotating shaft, clamping it from the bottom of the motor housing, completing axial fixation; the external motor drives the limiting cylinder 21 to rotate, and the turning tool descends to perform turning machining on the motor housing; When the limiting cylinder 21 rotates, the acceleration sensor 34 detects the vibration signal in real time. Because the motor housing has a mounting base, its uneven mass distribution causes eccentric centrifugal force to be generated during rotation, resulting in vibration. The acceleration sensor 34 transmits the vibration signal to the PLC controller. The controller calculates the required compensation centrifugal force based on the vibration amplitude and controls the drive motor to drive the lead screw 32 to rotate. When the lead screw 32 rotates, the two sliders 31 move relative to each other along the lead screw 32, causing the counterweight ball 33 to move away from the motor housing mounting base. When the counterweight ball 33 moves to a position symmetrical with the motor housing mounting base, the centrifugal forces generated by the two cancel each other out, and the limiting cylinder 21 returns to a dynamic balance state, avoiding vibration during turning. When the slider 31 moves, the wedge-shaped surface at the top of the slider 31 pushes the connecting frame 46 and the pressing block 44 to move axially along the limiting cylinder 21; when the pressing block 44 moves upward, its wedge-shaped surface pushes the support rod 41 to extend radially against the elastic force of the first spring 42, and the arc plate 43 at the end of the support rod 41 fits against the outer wall surface of the motor housing, increasing the rigidity of the upper part of the motor housing and preventing tool deflection during turning; the higher the rotation speed of the limiting cylinder 21, the greater the moving distance of the slider 31, the longer the distance that the pressing block 44 pushes the support rod 41 to extend, and the tighter the fit between the arc plate 43 and the motor housing; when the rotation speed of the limiting cylinder 21 decreases, the first spring 42 pulls the support rod 41 back to its original position, and the pressing force of the arc plate 43 on the motor housing decreases accordingly; When the support rod 41 extends radially, the adjusting plate 52 inside the support rod 41 slides relative to the support rod 41, and the alignment area of ​​the through hole 53 on the adjusting plate 52 and the through hole 53 on the support rod 41 changes; when the rotation speed of the limiting cylinder 21 increases and the extension amount of the support rod 41 increases, the alignment area of ​​the through hole 53 decreases, and the flow rate of the coolant sprayed from the spray hole 51 decreases; when the rotation speed of the limiting cylinder 21 decreases and the support rod 41 retracts, the alignment area of ​​the through hole 53 increases, and the flow rate of the coolant increases; the coolant in the reservoir 55 enters the spray hole 51 in the tray 22 through the cavity of the support rod 41 and the through hole 53 of the adjusting plate 52, and is sprayed upward from the bottom of the motor housing; the centrifugal force generated by the rotation of the motor housing causes the coolant to form a uniform coolant film on the inner wall of the motor housing, and the coolant film adheres to the cutting position to cool the turning area.

[0033] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
