[0002] A parallel double-spindle double-station intelligent turning center is an advanced numerical control machine tool. It integrates two spindles and two working areas, and can machine different parts at the same time or machine different parts of a large part on two spindles simultaneously. This design significantly improves production efficiency and reduces machining time and costs. Such equipment is very suitable for batch production and application scenarios that require high automation, flexibility, and high-precision machining, such as the fields of automobile manufacturing and aerospace component machining.

[0003] Existing parallel double-spindle double-station intelligent turning centers have a high degree of intelligence and are equipped with a double-spindle system, a double-station system, an automatic tool change system, a numerical control system, a loading and unloading system, etc., and have a complete workpiece production chain. However, in the preparatory stage of using the existing equipment, the turret and the tool holder need to be assembled. The tool holder is generally fixed to the turret surface by a plurality of bolts. The turret is generally a polyhedron structure, that is, a single turret needs to be fitted with a relatively large number of bolts. These bolts are mostly screwed manually, and the efficiency of manually assembling the tool holder and the turret needs to be improved. In addition, the motors for turret rotation of the existing equipment are mostly installed on the horizontal plane.

Detailed Embodiment

[0032] The following will describe in detail the embodiments of the present invention with reference to the accompanying drawings. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0033] Refer to Figure 1 and Figure 2, A parallel double-spindle double-station intelligent turning center, including a base plate 2. On the left and right sides of the base plate 2, there are vertically connected upright plates 3 extending upward. On the upper side of the base plate 2, there are symmetrically fixed support seats one 1 on the left and right. At the rear part of the upper side of the base plate 2, there is a vertically connected support seat two 5 extending upward. The support seat two 5 is distributed between the two support seats one 1. On the left side of the base plate 2, there is also a loading area 7 (the specific structure of the loading area 7 is not shown and can adopt a workpiece pushing system in the existing technology). On the right side of the base plate 2, there is also an unloading area 8 (the specific structure of the unloading area 8 is not shown and can adopt a workpiece pushing out system in the existing technology). On the left and right support seats one 1 and the rear support seat two 5, there is jointly arranged a processing mechanism 6 for synchronously machining two workpieces. Between the upper parts of the left and right upright plates 3, there is arranged a loading and unloading mechanism 4 for loading, unloading, and turning over the workpieces.

[0034] Refer to Figure 1 and Figure 2 , The processing mechanism 6 includes electric three-jaw chucks two 64 symmetrically rotatably connected to the upper side of the support seat two 5 through shaft rods. The shaft rods of the two electric three-jaw chucks two 64 are fixedly connected to the output ends of built-in motors. The built-in motors are installed in the support seat two 5. On one side of the left and right support seats one 1 close to the support seat two 5, there are installation inclined surfaces at 45° with the base plate 2. On the installation inclined surfaces, there are movably arranged tool-changing motors 63. The output end of the tool-changing motor 63 faces backward and is provided with a tool installation assembly 61 for installing various tools. Below the tool-changing motor 63, there is a tool alignment assembly 62 for controlling the tool to change its orientation.

[0035] During specific operation, two workpieces are clamped by the two electric three-jaw chucks two 64. The two built-in motors respectively control the two electric three-jaw chucks two 64 to rotate independently and generate a cutting effect with adjacent tools for machining. By the tool-changing motor 63, different machining tools are switched to align with the workpieces. The installation of the inclined surface is beneficial to chip discharge and coolant flow, which can not only protect the tool from heat damage but also reduce the risk of chips re-adhering to the workpiece, making the machining process more stable and ensuring the surface quality of the workpiece.

[0036] Refer to Figure 1 and Figure 2 , The loading and unloading mechanism 4 includes a pneumatic slide rail 41 fixedly connected between the upper parts of the left and right upright plates 3. On the pneumatic slide rail 41, there are slidably installed two pneumatic sliders 42. The two pneumatic sliders 42 are independently controlled. On both pneumatic sliders 42, there are arranged adjustment components 43 for changing the orientation of the workpiece.

[0037] During specific operation, by controlling the pneumatic slider 42 to move along the pneumatic slide rail 41, the movement control of the clamped workpiece is carried out.

[0038] By the combined use of the processing mechanism 6 and the loading and unloading mechanism 4, the synchronous machining of the two workpieces with forward and reverse installations can be completed.

[0039] Refer to Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown in, the tool mounting assembly 61 includes a turret 612 fixedly connected to the output end of the tool adjustment motor 63. The turret 612 has a regular polyhedron structure. A plurality of mounting holes are formed on each side surface of the turret 612. A docking post is fitted and embedded in each mounting hole. A tool holder 611 (the tool holder 611 is used for clamping various machining tools) is fixedly connected to the docking posts on the same side surface of the turret 612. A plurality of positioning holes are formed on one side surface of the tool holder 611 away from the central axis of the turret 612. A locking member 613 for synchronously locking each tool holder 611 on the turret 612 is provided on the rear side surface of the turret 612; the locking member 613 includes a mounting disc 614 fixedly connected to the rear side surface of the turret 612. The mounting disc 614 and the turret 612 are coaxial. The interior of the mounting disc 614 is hollow and a guide groove 6141 is formed on its rear side wall corresponding to each tool holder 611. A first connecting pin 6133 is slidably connected in the guide groove 6141. The outer end of the first connecting pin 6133 is fixedly connected to a pull plate 6132. The pull plate 6132 extends radially along the mounting disc 614 and its outer end is fixedly connected to a pressing plate 6134 by a plurality of bolts. A plurality of locking columns 6131 are fixedly connected to the side of the pressing plate 6134 close to the tool holder 611. The locking columns 6131 are distributed corresponding to the positioning holes on the tool holder 611 one by one.

[0040] Refer to Figure 6 、 Figure 7 and Figure 8 As shown in, a linkage member 615 for controlling the synchronous pressing of each pressing plate 6134 against each tool holder 611 is provided on the common setting of the center of the rear side surface of the mounting disc 614 and the inner ends of each first connecting pin 6133; the linkage member 615 includes a rotating rod 6156 rotatably connected to the center of the mounting disc 614. A turntable 6153 is fixedly connected to the outer end of the rotating rod 6156. A rotating plate 6158 is fixedly connected to the inner end of the rotating rod 6156. A plurality of obliquely offset grooves 6157 are formed on the rotating plate 6158 and are equally distributed in a circumferential manner.

The diamond hinge arm groups 6159 are sequentially hinged end to end. The two hinge pins of the diamond hinge arm group 6159 on the same radial line of the mounting disc 614 are respectively integrally fixedly connected to the first connecting pin 6133 and the second connecting pin 6154. The second connecting pin 6154 passes through the guide groove 6141 and extends to the outside of the mounting disc 614. A movable groove 6155 is formed on the pull plate 6132. The outer end of the second connecting pin 6154 is slidably connected in the movable groove 6155. A plurality of first connecting pins 6133 corresponding to the obliquely offset grooves 6157 extend and are slidably connected in the obliquely offset grooves 6157.

[0041] During specific operation, the turntable 6153 rotates to control the rotating rod 6156 to drive the rotating plate 6158 to rotate. The rotating plate 6158 drives each inclined slot 6157 to pull the first connecting pin 6133 therein to move radially along the guide slot 6141. All the diamond hinge arm groups 6159 deform synchronously to make all the first connecting pins 6133 move synchronously. The second connecting pin 6154 moves along the movable slot 6155 to ensure the consistent deformation of all the diamond hinge arm groups 6159 and improve the connection strength of the diamond hinge arm groups 6159. Then, the first connecting pin 6133 drives the pull plate 6132 to pull the pressing plate 6134 towards the tool holder 611. The pressing plate 6134, the locking column 6131 and the positioning hole cooperate to lock the tool holder 611 in a multi-point manner, effectively ensuring the installation stability of the tool holder 611. All the pressing plates 6134 are pressed synchronously to synchronously position and lock all the tool holders 611, effectively improving the installation efficiency of the tool holders 611. The pressing plate 6134 and the pull plate 6132 are connected by bolts, enabling the installation and disassembly of a single tool holder 611 when a single tool is damaged.

[0042] Refer to Figure 1 and Figure 5 As shown in FIGS. and, the tool alignment assembly 62 includes a plurality of electric push rods three 622 fixedly connected to the bottom of the tool adjustment motor 63.

The plurality of guide rods two 626 are fixedly connected between the left and right walls of the bracket 629. The bracket 629 is flush with the installation inclined surface. The upper end of the lead screw two 627 extends outside the bracket 629 and is fixedly connected to the output end of the motor four 628. The motor four 628 is fixedly connected outside the bracket 629. The tool alignment assembly 62 further includes a lead screw one 624 threadedly connected to the bottom of the bracket 629 and a plurality of guide rods one 625 slidably connected to the bottom of the bracket 629. The guide rods one 625 and the lead screw one 624 are both distributed in the front-rear direction. The lead screw one 624 is rotatably connected between the front and rear vertical walls of the installation inclined surface. The plurality of guide rods one 625 are fixedly connected between the front and rear vertical walls of the installation inclined surface. One end of the lead screw one 624 extends outside one side vertical wall of the installation inclined surface and is fixedly connected to the output end of the motor three 623. The motor three 623 is fixedly connected outside one side vertical wall of the installation inclined surface.

[0043] During specific operation, the lead screw two 627 is rotated by the motor four 628. The moving support 621 is driven by the lead screw two 627 to translate along the installation inclined plane, so that the cutting tool approaches the workpiece to be machined until the cutting tool to be used is on the coplanar plane of the central axis of the turret 612 and the central axis of the workpiece. The tool setting motor 63 is controlled by the electric push rod three 622 to move radially along the workpiece, so that the cutting tool to be used feeds radially along the workpiece. The lead screw one 624 is rotated by the motor three 623. The bracket 629 is driven by the lead screw one 624 to integrally control the cutting tool to be used to move along the central axis of the workpiece, so as to change the front-back dimension of the feed according to the machining requirements.

[0044] Refer to Figure 2 , Figure 3 and Figure 4 , the adjustment assembly 43 includes an electric push rod one 431 fixedly connected to the upper side of the pneumatic slider 42. The output end of the electric push rod one 431 faces forward and is fixedly connected with a mounting seat one 433. A motor one 432 is fixedly connected to the upper side of the mounting seat one 433. The output end of the motor one 432 rotates through the bottom of the mounting seat one 433 and is fixedly connected with a mounting seat two 434. An electric push rod two 435 is fixedly connected to the lower side of the mounting seat two 434. The output end of the electric push rod two 435 faces downward and is fixedly connected with a mounting seat three 438. The mounting seat three 438 is distributed at an angle of 45°. A motor two 436 is fixedly connected to the upper side of the mounting seat three 438. The output end of the motor two 436 rotates through the lower side of the mounting seat three 438 and is fixedly connected with a V-shaped frame 439. The included angle of the V-shaped frame 439 is 90° and its two sides are symmetrically distributed about the center of the output end of the motor two 436. Electric three-jaw chucks one 437 are fixedly connected to the outer ends of the two sides of the V-shaped frame 439.

[0045] During specific operation, the workpiece held is controlled by the first electric push rod 431 to move towards the second electric three-jaw chuck 64, enabling the workpiece to be loaded onto the second electric three-jaw chuck 64. When the first mounting seat 433 is controlled by the first electric push rod 431 to move forward, it can avoid interference between the loading and unloading mechanism 4 and the tool during the left-right translation operation. The workpiece held is rotated by the first motor 432 to change the facing direction of the workpiece held at the bottom. The workpiece held is controlled by the second electric push rod 435 to move up and down, so that the first electric three-jaw chuck 437 and the second electric three-jaw chuck 64 are aligned in the vertical direction. The V-shaped frame 439 is rotated by the second motor 436, and the workpiece with the machining surface facing down can be rotated to a vertical plane matching the second electric three-jaw chuck 64. When the two first electric three-jaw chucks 437 are aligned by controlling their respective first motors 432, the workpiece can be replaced, and the workpiece is transferred from the left first electric three-jaw chuck 437 to the right first electric three-jaw chuck 437. The workpiece is carried by the right first electric three-jaw chuck 437 and installed on the right second electric three-jaw chuck 64, so as to perform surface-changing machining on the workpiece. Specifically, when applied to surface-changing, the claws of the two first electric three-jaw chucks 437 need to be staggered.

[0046] Refer to Figure 6 、 Figure 7 and Figure 8 On the turntable 6153, a secondary locking bolt 6151 is threadedly connected. One end of the secondary locking bolt 6151 close to the mounting plate 614 is rotatably connected with a friction ring 6152. The surface of the friction ring 6152 is frosted, and the friction ring 615 is sleeved on the rotating rod 6156.

[0047] During specific operation, by rotating the secondary locking bolt 6151, the friction ring 6152 is pressed against the mounting plate 614, and the contact friction force is generated between the friction ring 6152 and the mounting plate 614 to prevent rotation and maintain the locking effect of the tool holder 611.

[0048] Refer to Figure 5 On the bottom of the mutually approaching side surfaces of the first supporting seats 1 on the left and right sides, chip collecting inclined surfaces 11 are provided.

[0049] During specific operation, the chips or coolant generated by machining are concentrated by the two inverted-eight-shaped chip collecting inclined surfaces 11, which is convenient for subsequent processing.

[0050] Before use, when assembling the turret 612, rotate the control lever 6156 through the turntable 6153 to drive the rotating plate 6158 to rotate. The rotating plate 6158 drives each inclined slot 6157 to pull the first connecting pin 6133 therein to move radially along the guide slot 6141. All the diamond hinge arms 6159 are synchronously deformed to move all the first connecting pins 6133 synchronously. Then, the first connecting pin 6133 drives the pull plate 6132 to pull the pressing plate 6134 to press against the tool holder 611.
