Description

Technical Field

[0001] The present invention relates to the technical field of compound machine tools, in particular to a vertical turning and milling compound machine tool. Background Art

[0002] In the field of mechanical processing, vertical turning and milling compound machine tools are widely used in the processing of various types of circular workpieces because they can complete multiple processing operations such as turning and milling on the same equipment, effectively reducing the number of workpiece clamping times and improving processing accuracy and efficiency.

[0003] At present, although conventional vertical turning and milling machines have turning and milling functions, they still have many limitations in practical applications. In terms of milling processing, for the milling of the end faces of circular workpieces, especially when processing square or waist-shaped holes, existing equipment often finds it difficult to flexibly meet the diverse hole distribution requirements. When it is necessary to process holes distributed in a circular array, most equipment can only achieve uniformly distributed hole processing. For non-uniformly distributed holes or circular holes of different diameters, the programming and operation are complex and difficult to adjust. It is impossible to easily achieve the self-setting of hole parameters. As a result, when faced with complex hole distribution processing requirements, the processing efficiency is low and the adaptability is poor. It is difficult to give full play to the advantages of turning and milling processing, especially when milling holes distributed in a circular array, its lack of flexibility and efficiency is more prominent. Summary of the Invention

[0010] A mounting plate fixed to the telescopic end of the milling actuator, a circumferential and radial position adjustment structure for limiting movement in the circumferential direction, and a locking structure for fixing the circumferential and radial position adjustment structure;

[0011] The circumferential and radial position adjustment structure includes a box body, a milling part is radially driven in the box body, and the milling part can be rotationally driven to a non-interference position.

[0012] Furthermore, a screw is rotatably connected in the box body, the screw is externally threadedly connected to a limit slider, and the limit slider is slidably connected to the box body, and a driving member 2 for driving the screw is installed on the box body;

[0013] The outer end of the box body passes through the box body and is coaxially connected to the clutch 2, the gear, the clutch 1, and the driving member 1 in sequence. The lower end of the mounting plate is connected to the ring gear relative to the clutch, and the ring gear is meshed with the gear.

[0014] The driving member 1 is arranged to move in a circular limiting manner with the box body.

[0015] Furthermore, a single-side rotation groove is provided in the limiting slider, the milling part is rotatably installed in the single-side rotation groove, and a driving part three for driving the milling part is installed on the limiting slider.

[0016] Furthermore, the milling execution assembly includes a guide rail slider pair 2 and a guide rail slider pair 1 fixed internally and externally to the lower end of the mounting plate, and the movable ends of the guide rail slider pair 2 and the guide rail slider pair 1 are respectively connected to the box body and the driving component 1.

[0017] Furthermore, a conductive block 1 is fixed to the upper end of the box body, and a conductive arc plate 1 is fixed to the lower end of the mounting plate, and the conductive arc plate 1 and the conductive block 1 are in electrical contact and electrically connected to the control component.

[0018] Furthermore, the locking structure includes at least two telescopic parts fixed to the lower end of the mounting plate, the telescopic ends of the telescopic parts are fixed with support plates, and the inner ends of at least two of the support plates are commonly fixed with an annular contact plate, and the annular contact plate can be in frictional contact with the box body.

[0019] Furthermore, it also includes a turning execution component, which includes a side plate fixed to the inner side of the vertical turning and milling compound bed, an arc rod and a conductive arc plate 2 are fixed to one side of the side plate, and a limit plate is fixed to the end of the arc rod away from the side plate, and a sliding sleeve on the arc rod is provided with a slide and a movable sleeve is provided with a spring, a turning telescopic drive part is fixed to the upper end of the slide, a turning part is fixed to the telescopic end of the turning telescopic drive part, a pump liquid pipe is fixed to the side of the turning part, and the pump liquid pipe is connected to a pump liquid part, and a conductive block 2 that is in electrical contact with the conductive arc plate 2 limit is fixed on the slide, and the conductive arc plate 2 and the conductive block 2 are electrically connected to the pump liquid part.

[0020] Furthermore, a time relay is fixed to the inner side surface of the vertical turning-milling compound bed, and the time relay is electrically connected to an alarm device.

[0021] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0022] 1. By setting up circumferential and radial position adjustment structures, the present invention can realize the synchronous dispersion or convergence movement of multiple milling execution components. It can be flexibly applied to the formation of circular holes of different diameters in an annular array, as well as holes with uniform circumferential orientation and different radial orientations. It effectively solves the problem that existing equipment is difficult to meet the needs of diversified hole distribution, and significantly improves the flexibility and adaptability of milling processing.

[0023] 2. The milling parts can be rotated and driven to a non-interference position. After determining the number of holes required for the workpiece, the milling parts that do not need milling can avoid interference, making it easy to flexibly adjust the number of parts involved in milling according to processing requirements, thereby improving the convenience of using the equipment.

[0024] 3. In the circumferential and radial position adjustment structure, the circumferential position and radial position can be adjusted independently through the cooperation of clutch 1, clutch 2, gears, ring gears and other components, and the synchronous radial movement of multiple milling parts can be achieved when milling annular array holes. When milling non-annular array holes, the radial position of each milling part can be adjusted individually. The adjustment method is flexible and diverse to meet the needs of different processing scenarios.

[0025] 4. The conductive block at the upper end of the box body forms electrical contact with the conductive arc plate at the lower end of the mounting plate and connects to the control component, which can feed back the circumferential position information of the milling part to the control component in real time, making it easier for the control component to accurately control the position of the milling part and improve the accuracy and efficiency of hole position adjustment.

[0026] 5. During milling operation, the locking structure can make friction contact with the box body through the annular contact plate to fix the circumferential and radial position adjustment structure, avoiding the milling quality affected by slight position deflection during the milling process and ensuring the stability of the milling operation.

[0027] 6. In the turning execution component, through the cooperation of the slide, conductive block 2, conductive arc plate 2 and pump fluid parts, the flow rate of the coolant can be automatically adjusted according to the change of turning resistance. When the turning resistance is large, the flow rate is increased to enhance cooling and lubrication, and when the resistance is small, the flow rate is reduced to save resources, realizing intelligent control of the coolant.

[0028] 7. The time relay fixed on the inside of the vertical turning-milling compound bed cooperates with the alarm device. When the coolant flow rate reaches the maximum and still cannot alleviate the large turning resistance and continues for a preset time, it can trigger the alarm in time to remind the staff to deal with the abnormal situation, avoid excessive wear of the tool or damage to the workpiece, and improve the safety of equipment operation.

DETAILED DESCRIPTION

[0039] In order to better understand the present technical solution, the present technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] Example: Refer to Figures 1 to 2 In order to solve the problem that the existing technology is difficult to flexibly meet the diverse hole position distribution requirements, the present invention provides a vertical turning and milling compound machine tool, including a vertical turning and milling compound bed 1, a milling telescopic drive member 3 and a workpiece positioning, clamping and rotating component 2 installed on the upper and lower inner walls of the vertical turning and milling compound bed 1, and a milling execution component 4 installed on the telescopic end of the milling telescopic drive member 3. The milling execution component 4 is electrically connected to a control component (which can be a PLC controller). Through the mutual cooperation of the vertical turning and milling compound bed 1, the workpiece positioning, clamping and rotating component 2, the milling telescopic drive member 3, the milling execution component 4 and the control component, multiple milling execution components 4 are realized to perform synchronous dispersed or retracted movements to be applicable In the annular array, circular holes of different diameters are formed, or holes with uniform circumferential orientation and different radial orientations. The milling telescopic drive 3 is used to vertically drive the milling execution components 4 that determine the milling holes to perform milling operations. It should be noted here that: 1. Suitable tools can be selected according to milling needs to mill square holes or waist-shaped holes. When milling square holes, the milling execution component 4 does not need to change its position relative to the workpiece, but when milling waist-shaped holes, the workpiece positioning clamping and rotating component 2 can be used to drive the workpiece to deflect at a corresponding angle to complete the milling of the waist-shaped hole; 2. The milling execution component 4 is not suitable for circular hole or groove processing operations to a certain extent. For this purpose, it can be replaced with a drilling tool.

[0041] The workpiece positioning, clamping and rotating assembly 2 can adopt common fixing methods in the prior art, such as mechanical chuck, vacuum adsorption and other fixing methods.

[0042] Among them, as the basic setting of the milling execution component 4, refer to Figures 3 to 5 The milling execution component 4 includes: a mounting plate 41 fixed to the telescopic end of the milling execution component 4, a circumferential and radial position adjustment structure 44 that limits movement in the circumferential direction, and a locking structure 45 for fixing the circumferential and radial position adjustment structure 44; the circumferential and radial position adjustment structure 44 includes a box body 445, and a milling part 4410 is radially driven in the box body 445, and the milling part 4410 can be rotated to a non-interference position. During actual milling, different workpieces have different quantities and hole position requirements. After determining the number of holes required for the workpiece, the number of milling parts 4410 is also determined accordingly, but the milling part 4410 has a vertical drive milling requirement, so the milling part 4410 that does not need milling work is rotated and driven to a non-interference position. At this time, the rotation angle range of the milling part 4410 is 30° to 90°. The maximum number of milling parts 4410 can be set as needed. The present invention Figure 5The maximum number of milling elements 4410 shown is five, but is not limited thereto.

[0043] In order to adjust the position of each milling part 4410 in the circumferential direction and radial direction, the following settings are made, referring to Figures 4 and 5 : A screw rod 446 is rotatably connected in the box body 445, and the external thread of the screw rod 446 is connected to the limit slider 448, and the limit slider 448 is slidably connected to the box body 445, and a driving member 2 447 for driving the screw rod 446 is installed on the box body 445; the outer end of the box body 445 passes through the box body 445 and is coaxially connected with the clutch 2 444, the gear 443, the clutch 1 442, and the driving member 1 441 in sequence, and the lower end of the mounting plate 41 is connected to the ring gear 4411 in relative clutch, that is, the ring gear 4411 is also fixed or movable relative to the mounting plate 41 through a separator to adapt to different usage states, and the ring gear 4411 and Gear 443 is engaged; driving member 1 441 and box body 445 are set for circumferential limiting motion, and the limiting here is specifically as follows: the milling execution component 4 includes a guide rail slider pair 2 43 and a guide rail slider pair 1 42 fixed to the lower end of the mounting plate 41 internally and externally, and the movable ends of the guide rail slider pair 2 43 and the guide rail slider pair 1 42 are respectively connected to the box body 445 and driving member 1 441, and one of the driving members 1 441 is in a relatively fixed position through the guide rail slider pair 1 42, that is, the position does not move, as a fixed point, that is, the circumferential position of the milling member 4410 here is also fixed, and is limited by the guide rail slider pair 2 43 and the guide rail slider pair 1 42.

[0044] When adjusting the circumferential position of the present invention, when milling the annular array holes, the position of each milling member 4410 must be adjusted separately, the clutch 1 442 is controlled to be in an engaged state, the clutch 2 444 is controlled to be in a disengaged state, and the ring gear 4411 is controlled to be in a fixed state, so that the drive of the driving member 1 441 does not affect the screw 446. Each driving member 1 441 drives the gear 443 to rotate through the clutch 1 442, and moves to the corresponding milling circumferential position under the condition that the gear 443 is meshed with the ring gear 4411;

[0045] After determining the circumferential orientation, the radial position is adjusted. When milling the annular array holes, it is necessary to keep the radial positions of the various milling parts 4410 uniform, and then control the clutch 1 442 corresponding to the relatively fixed milling part 4410 to be in an engaged state and the clutch 2 444 to be in a disengaged state, and the clutch 1 442 corresponding to the milling parts 4410 at other positions to be in a disengaged state and the clutch 2 444 to be in an engaged state, and the ring gear 4411 to be in an active state, and to be connected to the engaged clutch 1 442 The connected driving member 1 441 indirectly drives the gear 443, and the gear 443 drives the ring gear 4411 in the active state to synchronously drive the clutch 2 444 in other positions, so as to drive the screw 446 to drive the limiting slider 448 and the milling part 4410 to move synchronously and uniformly to the radial position; and when milling non-annular array holes, the clutch 1 442 and the clutch 2 444 at each position are in a disengaged state, and the screw 446 is driven separately by the driving member 2 447 to drive each milling part 4410 to move to a different radial position.

[0046] In order to realize the quickness of adjusting the circumferential orientation of the milling part 4410, the present invention fixes a conductive block 4413 on the upper end of the box body 445, and fixes a conductive arc plate 4412 on the lower end of the mounting plate 41, and the conductive arc plate 4412 and the conductive block 4413 are in electrical contact and electrically connected to the control component. The conductive arc plate 4412 is a non-circular arc structure and forms a variable resistor with the conductive block 4413. The variable resistor converts the current in the circuit where the conductive block 4413 and the conductive arc plate 4412 are located at each position into a fixed distance D of the milling part 4410, which corresponds to the circumferential angle orientation, with reference to Figure 6 , and a distance virtual line of the milling part 4410 with a fixed distance is set on the conductive arc plate 1 4412, which is divided into 1 to 8 equal parts, corresponding to multiple circular angle orientations, and has overlap, thus forming D1-8, D8, D7, D6, D5, D4 / 8, D3 / 6, D2 / 4 / 6 / 8, and the number after D indicates the number of equal parts, and each corresponds to a circular angle orientation. The control component enables the corresponding distance virtual line by knowing the number of equal parts, and obtains the positive value after simple addition and subtraction operations to know and control the activation of the distance virtual line closest to the use, and determines the rotation direction of the driving member 1 441 according to the positive or negative result of the addition and subtraction operations.

[0047] The setting for realizing the rotation of the milling part 4410 to the vertical state or the deflected state is as follows: a single-sided rotation groove is opened in the limiting slider 448, and the milling part 4410 is rotatably installed in the single-sided rotation groove. A driving part three 449 for driving the milling part 4410 is installed on the limiting slider 448. The milling part 4410 is driven to the vertical state or the deflected state by the driving part three 449. The milling part 4410 in the vertical state corresponds to the normal milling operation, and the milling part 4410 in the deflected state can avoid motion interference with other milling parts 4410 or the workpiece.

[0048] In order to increase the stability of the milling part 4410 performing milling operations, a locking structure 45 is provided. The locking structure 45 includes at least two telescopic parts 453 fixed to the lower end of the mounting plate 41. The telescopic end of the telescopic part 453 is fixed with a support plate 452. The inner ends of at least two support plates 452 are jointly fixed with an annular contact plate 451. When the telescopic part 453 is in the retracted state, the annular contact plate 451 makes frictional contact with the box body 445. The annular contact plate 451 exerts a relatively large pressure on the box body 445. In the present invention, when the milling operation is not in progress, the annular contact plate 451 is separated from the box body 445. When the milling operation is in progress, the annular contact plate 451 contacts the box body 445 and generates corresponding pressure to avoid slight position deflection during the milling operation, maintain the stability of the milling operation, and ensure the milling quality.

[0049] After determining the circumferential and radial positions of each milling part 4410, and when other milling parts 4410 that do not require milling operations will not interfere with normal milling, the milling telescopic drive part 3 synchronously drives multiple milling parts 4410 to perform milling processing on the workpiece that has been positioned and clamped by the workpiece and fixed by the rotating component 2.

[0050] During the turning process, the supply control method of lubricating coolant is relatively simple, usually using a fixed flow rate or manual adjustment based on experience. However, changes in factors such as the workpiece material and cutting parameters during the turning process will cause the turning resistance to fluctuate continuously, and the fixed coolant flow rate cannot match the actual resistance. When the resistance is large, if the coolant supply is insufficient, it will increase tool wear and affect the processing quality; when the resistance is small, excessive coolant supply will cause a waste of resources. In addition, when the coolant flow rate has reached the maximum and still cannot alleviate the large turning resistance, the existing equipment lacks an effective monitoring and alarm mechanism, which can easily lead to excessive tool wear or even damage to the workpiece, causing losses to production.

[0051] In order to solve the above technical problems, the present invention further includes a turning execution component 5, referring to Figures 7 and 8The turning execution component 5 includes a side plate 51 fixed to the inner side surface of the vertical turning and milling compound bed 1, and an arc rod 52 and a conductive arc plate 2 58 are fixed on one side of the side plate 51. A limit plate 53 is fixed to the end of the arc rod 52 away from the side plate 51, and a sliding sleeve on the arc rod 52 is provided with a slide 54 and a movable sleeve is provided with a spring 55. A turning telescopic driving member 56 is fixed to the upper end of the slide 54, and a turning member 57 is fixed to the telescopic end of the turning telescopic driving member 56. A pump liquid pipe 510 is fixed to the side of the turning member 57, and the pump liquid pipe 510 is connected to a pump liquid member (the driving source of the pump liquid member is a DC source). A conductive block 2 59 is fixed on the slide 54, which is in electrical contact with the conductive arc plate 2 58. The conductive arc plate 2 58 and the conductive block 2 59 are electrically connected to the pump liquid member. The turning part 57 is located on the side of the workpiece and is fed by the turning telescopic drive part 56. During the normal turning process, the turning friction force and the elastic resistance of the spring 55 form a dynamic balance, and the arc rod 52 coincides with the axis of the workpiece positioning clamping and rotating component 2 to maintain stable turning. When the turning resistance increases due to various factors in this process, the slide 54 can move more relative to the arc rod 52, and carry the conductive block 2 59 to move relative to the conductive arc plate 2 58, thereby changing the current in the pump liquid circuit, thereby changing the power of the pump liquid, thereby changing the flow rate of the coolant to increase the cooling and lubrication intensity and save coolant.

[0052] A time relay 511 is fixed to the inner side of the vertical milling bed 1 and is electrically connected to an alarm device. After the aforementioned cooling and lubrication intensity is changed, if the appropriate turning resistance cannot be maintained, the turning telescopic drive member 56 presses against the time relay 511 due to the turning resistance. After the pressure is maintained for a preset time (e.g., 10 seconds), the alarm device is activated through the time relay 511, emitting an audible and visual alarm, alerting personnel to promptly address the problem, indicating whether the machine is severely worn or has other problems.

[0053] It should also be noted that the driving members in the present invention are all rotary motors, and the telescopic members are electric telescopic rods. Of course, other existing devices with rotary drive or telescopic drive can also be used.

[0054] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0055] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
