Description

Technical Field

[0001] The invention relates to the field of double-axis turntables, and in particular to a double-axis turntable assembly device and a working method thereof. Background Art

[0002] As a common mechanical equipment, the dual-axis rotary table is widely used in various five-axis CNC machine tools. It can achieve precise rotational motion, meet different process and operation requirements, and complete multi-faceted processing in one clamping. In view of this, the dual-axis rotary table has very high assembly accuracy requirements. Its high-precision assembly requirements are crucial to ensure the processing quality of machine tools, improve production efficiency, and achieve high-precision process operations.

[0003] The dual-axis turntable assembly device is a tooling specifically used to assemble dual-axis turntables. The dual-axis turntable assembly devices commonly found on the current market are basically only applicable to the assembly of a certain type or two or three types of dual-axis turntables with similar specifications and sizes, and the application range is relatively narrow. If a new dual-axis turntable with specifications and sizes that are significantly different from those of previous dual-axis turntables is developed, a new dual-axis turntable assembly device production line will also need to be set up, which is costly and not conducive to fully releasing the production capacity of the existing dual-axis turntable assembly device production line. Therefore, if a universal assembly device suitable for dual-axis turntables of various specifications and sizes can be designed, there is no need to set up a new dual-axis turntable assembly device production line, which greatly reduces costs and fully releases the production capacity of the existing dual-axis turntable assembly device production line.

[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0062] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0064] The present invention proposes a dual-axis turntable assembly device, which has a slide 1 3 and a slide 2 5 with adjustable positions. The slide 1 3 and the slide 2 5 move with each other to cooperate and support a table body 10 and a stand 11 of different specifications and sizes, thereby completing the assembly operation of dual-axis turntables of different specifications and sizes. The dual-axis turntable assembly device has high versatility and a wide range of applications.

[0065] Specifically, in one embodiment of the invention, Figure 1As shown, the dual-axis turntable assembly device includes a workbench 1 and a linear motor 2 and a slide rail 4 arranged on the workbench 1. The slide rail 4 is located on both sides of the linear motor 2. A pair of slides 3 are arranged on the linear motor 2. The pair of slides 3 move horizontally towards or away from each other under the drive of the linear motor 2. The pair of slides 3 are used to place the table body 10. When the size of the table body 10 to be placed changes, the linear motor 2 is used to adjust the spacing between the pair of slides 3 to meet the needs of different sizes. The placement requirements of the table body 10 are met. Similarly, slides 2 5 are horizontally slidably installed on the slide rails 4 on both sides of the linear motor 1 2. The sliding directions of the slides 1 3 and 2 5 are parallel. Each slide 2 5 is used to place a table 11. For tables 11 of different sizes and models, the placement requirements of the table 11 are met by adjusting the position of the slide 2 5 on the slide rail 4. After the table 11 is placed in place and fixed, the slide 2 5 is moved along the slide rail 4 to drive the table 11 to approach the table body 10 and assemble them together.

[0066] like Fig.11 As shown, the dual-axis turntable includes a table body 10 and a pair of tables 11 rotatably installed on both sides of the table body 10, the pair of tables 11 are respectively installed on a pair of slides 5, and the table body 10 is installed on a pair of slides 3. For dual-axis turntables of different models and sizes, the spacing between the pair of slides 3 is adjusted by a linear motor 2 to meet the placement requirements of table bodies 10 of different sizes, and the position of the slide 25 is adjusted by moving the slide 25 on the slide rail 4 to meet the placement requirements of tables 11 of different sizes. After the assembly position of the table 11 and the table body 10 is adjusted in place, the slide 25 slides along the slide rail 4 to make the table 11 close to the table body 10, thereby completing the assembly of the dual-axis turntable, and the slide 13 and the slide 25 move with each other to cooperate and support and fix the table body 10 and the table 11 of different specifications and sizes, thereby completing the assembly operation of dual-axis turntables of different specifications and sizes.

[0067] The dual-axis turntable assembly device of the present embodiment has high versatility and a wide range of applications. It can meet the assembly requirements of dual-axis turntables of various specifications and sizes. Even if a new dual-axis turntable is developed whose specifications and sizes are greatly different from those of previous dual-axis turntables, there is no need to set up a new dual-axis turntable assembly device production line. By means of the mutual movement and cooperation of slide 1 3 and slide 2 5, the table body 10 and the table frame 11 of different specifications and sizes can be supported and fixed, thereby completing the assembly operation of dual-axis turntables of different specifications and sizes, and fully releasing the production capacity of the existing dual-axis turntable assembly device production line.

[0068] Specifically, Figure 1-Figure 3As shown, the slide 1 3 comprises: a slide 1 31 and a slide 2 33. The slide 1 31 is connected to a linear motor 1 2. The linear motor 1 2 drives the slide 1 31 to move horizontally back and forth to adjust the spacing between a pair of slides 1 3. The slide 1 31 is provided with a linear motor 2 32. The slide 2 33 is connected to the linear motor 2 32 and is slidably connected to the slide 1 31. The linear motor 2 32 drives the slide 2 33 to slide horizontally on the slide 1 31, and the sliding direction is perpendicular to the horizontal sliding direction of the slide 1 31. The slide 2 33 is provided with a pair of linear motors 3 and a pair of clamps. The pair of clamps are arranged at intervals and are respectively connected to a linear motor 3. The pair of clamps are driven by the pair of linear motors 3 to move closer to or away from each other. The sliding direction of the clamps is parallel to the sliding direction of the slide 2 33. With this design, the platform 10 can be clamped and fixed by the pair of clamps approaching each other. The use of linear motors to adjust the positions of the slides 1 31 and the slide 2 33 has the advantages of accurate and fast adjustment, and ensures the assembly accuracy of the dual-axis turntable.

[0069] Furthermore, the linear motor 3 includes a ball screw 35, a brake reduction motor 36, and a slider 37. Figure 3 As shown, the upper surface of the slide plate 33 is provided with a slide groove 34, and a slider 37 is horizontally slidably installed in the slide groove 34, and a ball screw 35 is penetrated by the slider 37, and the ball screw 35 is screwed to the slider 37, and the ball screw 35 is transmission connected with a brake reduction motor 36, and the brake reduction motor 36 is fixedly connected to the slide plate 33, and the ball screw 35 is located in the slide groove 34. When the brake reduction motor 36 is started, the ball screw 35 is driven to rotate, so that the slider 37 slides in the slide groove 34, and the slider 37 is connected to the clamp, and the slider 37 slides in the slide groove 34 to drive a pair of clamps to move closer to or away from each other. The use of a ball screw to adjust the position of the clamp can make the clamp move more accurately, which is convenient for the subsequent accurate control of the four clamps to simultaneously apply the same extrusion force to the platform 10.

[0070] Specifically, Figure 3As shown, the fixture includes: a slide 38, a pressure sensor 39 and a pressure measuring plate 310. The slide 38 is slidably connected to the slide plate 2 33 and is fixedly connected to the slide plate 1 37. The slide 38 is driven by the slide plate 1 37 to slide horizontally on the upper surface of the slide plate 2 33. The pressure sensor 39 is fixedly connected to the slide 38. The pressure measuring plate 310 is located on the side of the slide 38 facing the other slide 38 and is slidably connected to the slide 38. The sliding direction of the pressure measuring plate 310 is parallel to the sliding direction of the fixture. The pressure measuring plate 310 is connected to the pressure sensor 39. With this design, when a pair of fixtures on the slide plate 2 33 approach each other, when the pressure measuring plate 310 contacts the platform 10, the pressure measuring plate 310 squeezes the pressure sensor 39, so that the pressure sensor 39 detects a pressure signal.

[0071] The slide 3 of the present embodiment can drive the table body 10 to move left and right and front and back in the horizontal direction to adjust the position of the table body 10, so that the table body 10 can be quickly moved to the assembly position without lifting the table body 10 to adjust the position. The adjustment speed is fast and the efficiency is high, which improves the assembly efficiency of the dual-axis turntable. In addition, the four clamps simultaneously apply the same squeezing force to the table body 10 to ensure that the table body 10 will not be displaced in the process of clamping and fixing the table body 10, thereby ensuring high-precision assembly of the dual-axis turntable.

[0072] In this embodiment, if Figure 1 and Figure 2 As shown, the slide 2 5 includes: a slide 3 51, a mounting plate 53, a loading circular plate 512, and a fixing mechanism. The slide 3 51 is horizontally slidably connected to the slide rail 4, and the sliding direction is parallel to the sliding direction of the slide 1 31. Figure 2 As shown, a lifting device 52 is vertically fixedly installed on the slide plate 3 51. Common lifting devices 52 include linear motors, cylinders or hydraulic cylinders. Linear motors are preferred. Linear motors have high movement accuracy and precise control to ensure high-precision assembly of the dual-axis turntable. Figure 1 As shown, the mounting plate 53 is located above the slide plate 3 51 and is connected to the lifting device 52 . The lifting device 52 drives the mounting plate 53 to rise and fall to adjust the position of the mounting plate 53 .

[0073] In this embodiment, a rotation and translation mechanism is provided in the mounting plate 53; Figure 1 As shown, the carrier circular plate 512 is arranged on the upper surface of the mounting plate 53 and is rollingly connected to the mounting plate 53. The rotation and translation mechanism is connected to the carrier circular plate 512. The rotation and translation mechanism drives the carrier circular plate 512 to translate horizontally or translate horizontally while rotating around its own vertical center axis. The direction of the horizontal translation of the carrier circular plate 512 is perpendicular to the horizontal sliding direction of the slide plate three 51.

[0074] Specifically, Figure 1 and Figure 2 , Figure 7-Figure 9 As shown, the rotation and translation mechanism includes a rotating shaft 57, a gear 1 56, an electromagnetic brake 510, a linear motor 4, a rack 519, and a push-pull device 520; Figure 2 As shown, the upper surface of the mounting plate 53 is provided with a second slide groove 531, and the bottom of the second slide groove 531 is provided with a third slide groove 54, the width of the third slide groove 54 is greater than that of the second slide groove 531, and the bottom of the third slide groove 54 is provided with a fourth slide groove 55, and the gear 1 56 is slidably installed in the third slide groove 54, and the bottom surface and top surface of the third slide groove 54 are slidably connected with the gear 1 56, and the gear 1 56 is limited by the third slide groove 54 so that it cannot move up and down, ensuring that it can reliably and accurately drive the object-carrying circular plate 512 to rotate. The electromagnetic brake 510 is slidably installed in the fourth slide groove 55, and the linear motor 4 is fixedly installed in the fourth slide groove 55. The electromagnetic brake 510 is connected to the linear motor 4, and the electromagnetic brake 510 is driven by the linear motor 4 to slide horizontally in the fourth slide groove 55, and the sliding direction is parallel to the sliding direction of the slide plate 2 33. The rotating shaft 57 is vertically arranged, and the lower end of the rotating shaft 57 is connected to the electromagnetic brake 510. When the rotating shaft 57 does not need to rotate, the electromagnetic brake 510 brakes the rotating shaft 57 so that the carrier circular plate 512 only moves horizontally. The electromagnetic brake 510 releases the brake on the rotating shaft 57. When the gear 1 56 rotates, the gear 1 56 drives the carrier circular plate 512 to rotate through the rotating shaft 57 to achieve horizontal translation of the carrier circular plate 512 while rotating around its own vertical center axis. The upper end of the rotating shaft 57 passes through the gear 1 56 and is coaxially fixedly connected to the carrier circular plate 512. The gear 1 56 is coaxially fixedly connected to the rotating shaft 57. The rotating shaft 57 is slidably connected to the groove wall of the second slide groove 531. This design can prevent the rotating shaft 57 from deflecting during the rotation process. Figure 2As shown, a slot 517 is provided on the slot wall of the slot 3 54, the rack 519 is horizontally slidably installed in the slot 517, the sliding direction of the rack 519 is parallel to the sliding direction of the slide plate 3 51, the push-pull device 520 is fixedly connected to the mounting plate 53, the rack 519 is connected to the push-pull device 520, and the rack 519 is driven by the push-pull device 520 to slide horizontally in the slot 5 517 to mesh with or separate from the gear 1 56. When the rack 519 approaches the gear 1 56 and meshes with the gear 1 56, the linear motor 4 drives the electromagnetic brake 510 to slide horizontally in the slot 4 55 to make The gear 56 translates horizontally while rotating around its own vertical center axis (provided that the rotating shaft 57 is not braked and the rotating shaft 57 can rotate freely), thereby driving the loading circular plate 512 to translate horizontally while rotating around its own vertical center axis. The stand 11 is placed on the loading circular plate 512. Therefore, the loading circular plate 512 translates horizontally while rotating around its own vertical center axis, so that the position of the stand 11 can be quickly adjusted to enable it to move quickly to the assembly position. When the loading circular plate 512 does not need to rotate, the control rack 519 is separated from the gear 56, and the rotating shaft 57 is braked by the electromagnetic brake 510 so that the loading circular plate 512 can only translate horizontally.

[0075] Preferably, the push-pull device 520 is a push rod motor, which has high movement accuracy and precise control, thereby ensuring high-precision assembly of the dual-axis turntable.

[0076] Furthermore, in order to make the rack 519 slide smoothly in the slide groove 517, Figure 2 As shown, a slide plate 4 518 is horizontally slidably installed in the slide groove 517, and the slide plate 4 518 is fixedly connected to the rack 519 and the push-pull device 520.

[0077] Specifically, Figure 1 and Figure 2 , Figure 7-Figure 9 As shown, the linear motor four includes a ball screw two 58, a brake reduction motor two 59, and a slider two 511. The ball screw two 58 is located in the slide groove four 55, and the slider two 511 is screwed to the ball screw two 58. At the same time, the slider two 511 is horizontally slidably installed in the slide groove four 55, and the sliding direction is parallel to the sliding direction of the slide plate two 33. The brake reduction motor two 59 is fixedly connected to the mounting plate 53, and the ball screw two 58 is driven to rotate by the brake reduction motor two 59, thereby driving the slider two 511 to slide horizontally in the slide groove four 55. The slider two 511 is fixedly connected to the electromagnetic brake 510, so it can drive the electromagnetic brake 510 to slide horizontally synchronously. The use of ball screw two 58 to move the carrier circular plate 512 horizontally can make the movement accuracy of the carrier circular plate 512 higher and the control more precise, thereby ensuring the high-precision assembly of the dual-axis turntable.

[0078] In this embodiment, if Figure 1 and Figure 2 , Figure 7-Figure 9 As shown, the upper surface of the carrier circular plate 512 is provided with a positioning pin 516 coaxial with the carrier circular plate 512 and a plurality of annular grooves 515 of different diameters. The positioning pin 516 and the carrier circular plate 512 are fixedly connected. The positioning pin 516 is used to position the stand 11 so that the stand 11 can be quickly and accurately placed at a specified position on the carrier circular plate 512. Then, the carrier circular plate 512 drives the stand 11 to rotate or translate to quickly adjust the stand 11 to the assembly position. The provision of the positioning pin 516 can improve the speed and efficiency of the position movement adjustment of the stand 11.

[0079] In this embodiment, the cross section of the annular groove 515 is an inverted T-shape. Fig.10 As shown, a T-shaped slider 532 is slidably installed in the annular groove 515. The cross-section of the annular groove 515 is set in an inverted T shape so that the T-shaped slider 532 will not leave the annular groove 515 and can only slide along the circumference of the annular groove 515. A bolt 533 is screwed on the T-shaped slider 532, and a pressure plate 534 is movably sleeved on the bolt 533. When the position of the platform 11 is adjusted to the assembly position, the T-shaped slider 532 is moved to slide along the annular groove 515 so that the pressure plate 534 is close to the platform 11, and then one end of the pressure plate 534 is placed on the platform 11, and then the bolt 533 is tightened so that one end of the pressure plate 534 presses and fixes the platform 11 on the upper surface of the object-carrying circular plate 512 to complete the fixation of the platform 11.

[0080] In this embodiment, if Figure 7-Figure 9 As shown, a plurality of rolling balls 514 are rollingly mounted on the lower surface of the object-carrying circular plate 512, and the rolling balls 514 are rollingly connected to the upper surface of the mounting plate 53. This design can minimize the friction resistance when the object-carrying circular plate 512 slides, and avoid rapid wear of the object-carrying circular plate 512 and the mounting plate 53. Furthermore, in order to facilitate the disassembly and assembly of the rolling balls 514, as shown in FIG. Figure 7-Figure 9 As shown, a limiting plate 513 is detachably fixedly installed on the lower surface of the object-carrying circular plate 512, and the ball 514 passes through the limiting plate 513. The limiting plate 513 limits the ball 514 so that the ball 514 does not fall. When the limiting plate 513 is removed, the ball 514 can be separated from the lower surface of the object-carrying circular plate 512.

[0081] In this embodiment, one end of the fixing mechanism is connected to the slide plate 3 51, and the other end is connected to the workbench 1, so as to fix the slide plate 3 51 and the workbench 1 after the slide plate 3 51 slides into place. Figure 1 , Figure 2 , Figure 4-Figure 6As shown, the fixing mechanism includes a machine box 524, a screw 522, and a mounting seat 521. The machine box 524 is hinged to the workbench 1 through a pin 525. The machine box 524 has a box cover. The machine box 524 is provided with a brake reduction motor 3 529, a pair of baffles 526, a pair of thrust bearings 527, and a gear 2 528. The pair of baffles 526 and the pair of thrust bearings 527 are arranged at intervals. The pair of baffles 526 are detachably fixedly connected to the inner wall of the machine box 524. The gear 2 528 is located between the pair of thrust bearings 527 and is close to the thrust bearings 527. The gear 2 528 is coaxial with the thrust bearing 527. The pair of thrust bearings 527 are located between the pair of baffles 526 and are arranged close to the baffles 526. This design allows the gear 2 528 to only move by itself. The brake reduction motor three 529 is connected to the gear two 528 through the gear three 530, thereby driving the gear two 528 to rotate, and the screw rod 522 slides axially through the machine box 524, and the gear two 528 is coaxially sleeved on the screw rod 522 and screwed with the screw rod 522. The gear two 528 rotates to drive the screw rod 522 to move axially, and the mounting seat 521 is hinged to one end of the screw rod 522, and the mounting seat 521 is fixedly connected to the slide plate three 51, and the hinge center axis of the screw rod 522 and the mounting seat 521 is parallel to the hinge center axis of the machine box 524 and the workbench 1. With this design, the slide plate three 51 can smoothly drive the screw rod 522 to swing when sliding along the slide rail 4, and the fixing mechanism does not affect the sliding of the slide plate three 51 along the slide rail 4.

[0082] In this embodiment, further, a long hole 523 is provided on the upper surface of the workbench 1, the machine box 524 is located inside the workbench 1 and is hinged to the workbench 1 through a pin 525, and the other end of the screw rod 522 passes through the long hole 523 and extends into the interior of the workbench 1. This design can protect the fixing mechanism and prevent it from being damaged by collision with foreign objects.

[0083] The slide 2 5 of the present embodiment can drive the table 11 to move left and right, front and back in the horizontal direction, and drive the table 11 to rotate around the vertical axis to adjust the position of the table 11, so that the table 11 can be quickly moved to the assembly position and quickly assembled with the table body 10. There is no need to lift and adjust the position of the table 11 and assemble it with the table body 10. The adjustment and assembly speed are fast and efficient, which improves the assembly efficiency of the dual-axis turntable.

[0084] In this embodiment, if Figure 1As shown, a rotating motor 6 is also fixedly installed on the workbench 1, and the rotating motor 6 is connected to one end of the swing arm 7 to drive the swing arm 7 to rotate around the vertical axis of the rotating motor 6. A rotating motor 2 8 is installed on the other end of the swing arm 7, and the rotating motor 2 8 is connected to a laser scanning measuring instrument 9. The laser scanning measuring instrument 9 is driven to rotate around the vertical axis by the rotating motor 2 8. The rotating motor 1 6 and the rotating motor 2 8 drive the laser scanning measuring instrument 9 to move to scan and model the table body 10 and a pair of stands 11 on the slide 1 3 and the slide 2 5, and quickly obtain the positions of the table body 10 and the pair of stands 11. Then, the computer controls the slide 1 3 and the slide 2 5 according to the positions of the table body 10 and the pair of stands 11 at this time to quickly adjust the table body 10 and the pair of stands 11 to the assembly position and complete the assembly, with fast assembly speed, high efficiency and high assembly accuracy.

[0085] The working method of the dual-axis turntable assembly device of this embodiment is described in detail below.

[0086] The working method of the dual-axis turntable assembly device of this embodiment is as follows:

[0087] S1. According to the specifications and dimensions of the platform 10, the linear motor 2 is controlled to adjust the spacing between a pair of slides 3 so as to meet the placement requirements of the platform 10. Then, the slide 2 5 is slid along the slide rail 4 to a suitable position to facilitate the subsequent placement of the platform 11. It is also necessary to ensure that the placed platform 11 does not collide with the platform 10 on the slide 3. This process can be completed by manual control. After the position of the pair of slides 3 is adjusted in place, the linear motor 2 is powered off to prevent the pair of slides 3 from sliding by themselves. After the position of the slide 2 5 is adjusted in place, the fixing mechanism is controlled to lock the slide 2 5 so that the slide 2 5 cannot slide along the slide rail 4.

[0088] S2, using a lifting device to lift the platform 10 and place it on the slide plate 2 33 of a pair of slides 1 3, and then using a lifting device to lift the pair of platforms 11 and place them on the object-carrying circular plates 512 of a pair of slides 2 5, respectively, and insert the positioning pins 516 on the object-carrying circular plates 512 into the pin holes on the bottom of the platforms 11, thereby completing the initial positioning of the platforms 11;

[0089] S3, control the rotary motor 1 6 and the rotary motor 2 8 to drive the laser scanning measuring instrument 9 to move the table 10 and the pair of gantry 11 on the slide 1 3 and the slide 2 5 to scan and model the table 10 and the pair of gantry 11 to obtain the positions of the table 10 and the pair of gantry 11. If necessary, the laser scanning measuring instrument 9 can be set at both ends of the workbench 1. Figure 1As shown, it is ensured that the table body 10 and the pair of stands 11 are completely scanned; the scanned data is transmitted to the computer, and the computer analyzes and processes to obtain the positions of the table body 10 and the pair of stands 11 on the slide 1 3 and the slide 2 5 at this time, and then calculates the assembly position of the table body 10 and the pair of stands 11 and the moving adjustment path from this position to the assembly position, and produces the adjustment control method, and finally the computer controls the slide 1 3 and the slide 2 5 to adjust the table body 10 and the pair of stands 11 to the assembly position;

[0090] Specifically, when adjusting the platform 10, the linear motor 2 32 on the pair of slides 1 3 is controlled to adjust the position of the pair of slide plates 2 33, so that the platform 10 placed on the pair of slide plates 2 33 rotates and / or translates until the platform 10 moves to the assembly position, and then the brake reduction motor 1 36 is started to drive the pressure plate 310 to approach the platform 10. When one or more (not all) pressure plates 310 are in contact with the platform 10, the pressure sensor 39 detects a pressure signal. At this time, the pressure plate 310 is immediately controlled to stop moving, and wait until the remaining pressure plates 310 are also in contact with the platform 10 and the pressure sensor 39 also detects a pressure signal of the same size (the movement speed of each pressure plate 310 is the same, but the distance from the platform 10 is The distances are not always the same. In most cases, the distances are different. Therefore, they will not contact the platform 10 at the same time. The pressure plate 310 that contacts the platform 10 first needs to pause and wait for the subsequent pressure plate 310 to contact the platform 10. Then, all the pressure plates 310 apply the same squeezing force to the platform 10 to clamp the platform 10), and then control all the brake reduction motors 36 to start at the same time, so that all the pressure plates 310 apply the same squeezing force to the platform 10 until the platform 10 is clamped. This design aims to prevent the problem that the pressure plates 310 push the platform 10 to move due to different squeezing forces during the process of clamping the platform 10, thereby ensuring the assembly accuracy of the dual-axis turntable.

[0091] Specifically, when adjusting the platform 11, the brake reduction motor 2 59 is controlled to drive the ball screw 2 58 to rotate, and the electromagnetic brake 510 brakes the rotating shaft 57, so that the object-carrying circular plate 512 only moves horizontally. During the movement, the push-pull device 520 is controlled to push the rack 519 to contact and mesh with the gear 1 56, and at the same time, the electromagnetic brake 510 is released from the braking of the rotating shaft 57, so that the rotating shaft 57 drives the object-carrying circular plate 512 to rotate and adjust the orientation of the platform 11. After the object-carrying circular plate 512 rotates into place, the rack 519 is controlled to separate from the gear 1 56, and the electromagnetic brake 510 is restored to brake the rotating shaft 57 until the object-carrying circular plate 512 moves horizontally into place;

[0092] Then the rotary motor 1 6 and the rotary motor 2 8 drive the laser scanning measuring instrument 9 to move twice to perform a second scanning modeling on the table 10 and the pair of stands 11 on the slide 1 3 and the slide 2 5, and confirm that the table 10 and the pair of stands 11 are moved to the assembly position, otherwise, the slide 1 3 and the slide 2 5 are continuously controlled to move to adjust the table 10 and the pair of stands 11 to the assembly position;

[0093] S4, after the stand 11 is adjusted to the assembly position, the T-shaped slider 532 is slid along the annular groove 515 to approach the stand 11, and then one end of the pressing plate 534 is placed on the stand 11, and the fixing bolt 533 is tightened so that the pressing plate 534 presses and fixes the stand 11 on the object-carrying circular plate 512;

[0094] S5. After the platform 10 and a pair of stands 11 are fixed, the fixing mechanism is controlled to unlock the slide plate three 51, that is, the brake reduction motor three 529 is controlled to drive the gear two 528 to rotate, so that the slide two 5 can slide along the slide rail 4 to drive the pair of stands 11 close to the platform body 10, and complete the assembly with the platform body 10. After the assembly is completed, the fixation of the platform body 10 and the pair of stands 11 is released, and the assembled dual-axis turntable can be lifted away using lifting equipment.

[0095] In this embodiment, during the sliding of slide 2 5 along the slide rail 4, the brake reduction motor 3 529 needs to cooperate to drive gear 2 528 to rotate. The rotation of gear 2 528 drives the screw 522 to move axially so that slide 2 5 can slide smoothly along the slide rail 4. When slide 2 5 slides into place along the slide rail 4, the brake reduction motor 3 529 no longer rotates, and the fixing mechanism locks slide 2 5 and fixes it to the workbench 1.

[0096] In this embodiment, the central axis of the positioning pin 516 and the central axis of the hole of the stand 11 intersect vertically. With this design, the stand 11 can be adjusted into place by rotating the object-carrying circular plate 512 in coordination with the horizontal movement.

[0097] Furthermore, when adjusting the platform 11, the lifting device 52 can be controlled to adjust the height of the platform 11 as needed, thereby completing the adjustment of the platform 11 to the assembly position.

[0098] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
