[0058] Reference Figs. 1-6 For an embodiment of the utility model, a three-degree-of-freedom adjustable support tool is proposed, which comprises: a tool base 1; a longitudinal adjusting mechanism 2 arranged on the tool base 1; a transverse adjusting mechanism 3 arranged on the longitudinal adjusting mechanism 2; a vertical adjusting mechanism 4 arranged on the transverse adjusting mechanism 3; a workpiece interface plate 5 arranged on the vertical adjusting mechanism 4, the workpiece interface plate 5 has a mounting hole 501, the mounting hole 501 is used for accommodating a workpiece; a centering adjusting part 6 arranged on one side of the workpiece interface plate 5, the centering adjusting part 6 has a clamping part 604 and an indicating part 6051, the centering adjusting part 6 is used for aligning the workpiece with the mounting hole 501.

[0059] In the above scheme, first, the tooling is placed in the appropriate working position. When the workpiece needs to be installed, the longitudinal adjustment mechanism 2 can realize the position adjustment of the workpiece in the longitudinal direction. When the longitudinal adjustment mechanism 2 is working, the first drive 205 is started to drive the gear to rotate, and since the gear is in meshing transmission with the rack 202 provided on the tooling base 1, the longitudinal adjustment base 201 installed on the slide rail moves along the slide rail, thereby realizing the change of the longitudinal position. Then, the transverse adjustment mechanism 3 performs transverse position adjustment. The second drive 304 drives the screw rod 303 to rotate, since the screw rod 303 is in threaded connection with the threaded hole of the fixed block 3050 at the bottom of the transverse adjustment base 301, and the transverse adjustment base 301 is slidingly arranged on the slide rail on the longitudinal adjustment base 201, the rotation of the screw rod 303 drives the transverse adjustment base 301 to move in the transverse direction. Then, the vertical adjustment mechanism 4 is responsible for the adjustment in the vertical direction. The third drive 402 drives the elevator 401 to act, and the elevator 401 drives the workpiece interface plate 5 to move in the vertical direction, so as to accurately adjust the height position of the workpiece. In the process of installing the workpiece into the mounting hole 501 of the workpiece interface plate 5, the centering adjusting piece 6 plays a role. The workpiece is close to the workpiece interface plate 5, and by operating the crossbeam 601 and the sliding arm 603 of the centering adjusting piece 6, the workpiece position is adjusted by using the clamping part 604 on the sliding arm 603, so that the workpiece is aligned with the mounting hole 501. The indicating part 6051 on the deflection rod 605 can help to determine the center position of the workpiece.

[0060] The three-degree-of-freedom adjustable support tooling can accurately adjust the workpiece in the longitudinal, transverse and vertical directions, meets the installation requirements of workpieces of different shapes and sizes in complex space positions, and greatly improves the adaptability of the tooling to different workpieces. The design of the centering adjusting piece 6 enables the workpiece to be more accurately and conveniently aligned with the mounting hole 501, reduces the error in the installation process, improves the precision and efficiency of the workpiece installation, and thus guarantees the quality of the subsequent machining or detection process.

[0061] Further, the longitudinal adjustment mechanism 2 comprises: a plurality of first slide rails 204, which are symmetrically arranged on both sides of the top surface of the tooling base 1; a longitudinal adjustment base 201, which is slidingly arranged on the first slide rails 204; a first drive 205, which is arranged on the longitudinal adjustment base 201; a rack 202, which is arranged on the tooling base 1; and a first gear 203, which is arranged on the output end of the first drive 205, and the first gear 203 is in meshing transmission with the rack 202.

[0062] In the above scheme, when longitudinal adjustment is needed, the first driver 205 receives the control signal to start working. For example, if the longitudinal base 201 needs to be moved in a certain direction, the first driver 205 drives the gear to rotate in the corresponding direction. Since the rack 202 is fixed on the tool base 1, the meshing of the gear and the rack 202 will make the gear roll along the rack 202, thereby driving the longitudinal base 201 to slide on the slide rails symmetrically arranged on the top surface of the tool base 1, realizing accurate adjustment of the longitudinal position. Through the meshing transmission mode of the gear and the rack 202, combined with the slide rail structure, the longitudinal adjustment process is stable and accurate. The symmetrical arrangement of the plurality of slide rails ensures the stability of the longitudinal base 201 during movement, effectively preventing problems such as deflection, thereby improving the reliability and adjustment accuracy of the entire longitudinal adjustment mechanism 2.

[0063] Further, the horizontal adjustment mechanism 3 comprises: a plurality of second slide rails 302, the plurality of second slide rails 302 being symmetrically arranged on the top surface of the longitudinal base 201; a horizontal base 301, which is slidingly arranged on the second slide rails 302; a second driver 304, which is arranged on the longitudinal base 201; a fixed block 3050, which is arranged at the bottom of the horizontal base 301, the fixed block 3050 having a first threaded hole 3051; and a lead screw 303, which is rotatably arranged at the bottom of the horizontal base 301, one end of the lead screw 303 being arranged on the output end of the second driver 304, and the other end of the lead screw 303 penetrating through and being threadedly connected with the first threaded hole 3051.

[0064] In the above scheme, the second driver 304 is started, and the second driver 304 drives the lead screw 303 to rotate. Since the lead screw 303 is threadedly connected with the threaded hole of the fixed block 3050 at the bottom of the horizontal base 301, the rotational movement of the lead screw 303 is converted into the linear movement of the horizontal base 301 in the direction of the slide rails on the top surface of the longitudinal base 201. In this process, the slide rails provide a guiding effect for the movement of the horizontal base 301, ensuring the accuracy of the movement direction. The transmission mode of the lead screw 303 realizes high-precision horizontal position adjustment. This transmission mode has high transmission accuracy and positioning accuracy, and can accurately convert the rotational movement of the driver into the linear movement of the horizontal base 301. At the same time, the existence of the slide rails enhances the stability of the movement of the horizontal base 301, reduces the shaking, and improves the working performance of the entire horizontal adjustment mechanism 3.

[0065] Further, the vertical adjustment mechanism 4 comprises: an elevator 401, which is arranged on the horizontal base 301, and the workpiece interface plate 5 is arranged on the elevator 401; and a third driver 402, which is arranged on the horizontal base 301, the third driver 402 being in transmission connection with the elevator, and the third driver 402 being used to drive the elevator 401 to act.

[0066] In the above scheme, the third driver 402 starts to drive the elevator 401. The elevator 401 drives the workpiece interface plate 5 arranged thereon to ascend or descend in the vertical direction according to the driving direction and speed of the driver. For example, when the workpiece interface plate 5 needs to be raised, the third driver 402 drives the lifting component of the elevator 401 to move upward, so as to realize the position adjustment of the workpiece in the vertical direction. The vertical adjustment mechanism 4 can realize stable and accurate vertical adjustment through the cooperation of the special elevator 401 and the driver. The workpiece installation with different height requirements is met, the adaptability of the entire tooling in the vertical dimension is ensured, and the overall precision of the workpiece installation is improved.

[0067] Further, the centering adjusting member 6 comprises a cross beam 601 hingedly arranged on the workpiece interface plate 5, and the cross beam 601 has a sliding groove 602; a plurality of sliding arms 603 are slidingly arranged in the sliding groove 602, and the plurality of sliding arms 603 are symmetrically arranged, and a clamping part 604 is arranged on the sliding arm 603; a deflection rod 605 is hingedly arranged at the middle part of the cross beam 601, and an indicating part 6051 is arranged on the deflection rod 605, and the indicating part 6051 is used to indicate the center position of the workpiece.

[0068] In the above scheme, first, the cross beam 601 can rotate around the hinge point of the workpiece interface plate 5, so as to facilitate the adjustment of the angle. The plurality of sliding arms 603 slide in the sliding groove 602 of the cross beam 601, and the position can be adjusted according to the size and shape of the workpiece. In operation, the workpiece is close to the workpiece interface plate 5, and the clamping part 604 is close to the workpiece by moving the sliding arm 603. The clamping part 604 on each sliding arm 603 realizes the preliminary positioning of the workpiece through the sliding of the sliding strip 6041 in the sliding groove 602 and the abutment of the rotating wheel 6042 on the outer wall of the workpiece. At the same time, the indicating part 6051 on the deflection rod 605 can display the relative position between the center of the workpiece and the center of the mounting hole 501, and further assist the centering adjustment. The adjustable structure of the centering adjusting member 6 can adapt to workpieces with different sizes and shapes. Through the flexible operation of the sliding arm 603 and the clamping part 604, the workpiece can be accurately positioned, and the centering accuracy is improved. The existence of the indicating part 6051 provides an intuitive reference for the operator, facilitates the rapid completion of the centering operation, and reduces the centering time and error.

[0069] Further, the sliding arm 603 has the sliding groove 602, and the clamping part 604 comprises a sliding strip 6041 slidingly arranged in the sliding groove 602; a plurality of rotating wheels 6042 are arranged, at least two rotating wheels 6042 are arranged at one end of each sliding strip 6041, and the rotating wheel 6042 is used to abut on the outer wall of the workpiece.

[0070] In the above scheme, when adjusting the position of the workpiece, the slide bar 6041 can slide in the sliding groove 602 of the sliding arm 603 to adapt to workpieces of different diameters. A plurality of rotating wheels 6042 at one end of each slide bar 6041 are in contact with the outer wall of the workpiece. When the position of the workpiece changes slightly during centering, the rotating wheels 6042 can roll on the outer wall of the workpiece, reducing friction and damage to the surface of the workpiece, and better adapting to the position adjustment of the workpiece to ensure the stability of clamping. The design of the slide bar 6041 and the rotating wheel 6042 enables the clamping part 604 to better adapt to workpieces of different sizes and protects the surface of the workpiece during centering. The rolling characteristics of the rotating wheel 6042 reduce the friction on the workpiece, which is beneficial to improve the accuracy and efficiency of centering adjustment, and avoids quality problems such as scratches on the surface of the workpiece caused by clamping.

[0071] Further, the clamping part 604 further comprises an adjusting screw 607 rotatably arranged on the sliding arm 603, the slide bar 6041 has a second threaded hole, the adjusting screw 607 is threadedly connected with the second threaded hole, and the adjusting screw 607 is used for adjusting the position of the slide bar 6041 in the sliding groove 602.

[0072] In the above scheme, when it is necessary to adjust the position of the slide bar 6041 in the sliding groove 602, the adjusting screw 607 is rotated. Since the adjusting screw 607 is threadedly connected with the threaded hole of the slide bar 6041, rotating the adjusting screw 607 will make the slide bar 6041 move axially in the sliding groove 602, thereby changing the distance between the rotating wheel 6042 and the workpiece, and realizing more accurate clamping of workpieces of different sizes. The existence of the adjusting screw 607 provides an accurate control means for the position adjustment of the slide bar 6041. By rotating the adjusting screw 607, fine adjustment can be realized, which further improves the adaptability of the clamping part 604 to workpieces of different sizes and the accuracy of clamping, and helps to better complete the centering operation and ensure the installation accuracy of the workpiece.

[0073] Further, the side surface of the slide bar 6041 has a plurality of first through holes 606 arranged at intervals, the sliding arm 603 has a second through hole 6031, and the clamping part 604 further comprises a plug 608 sequentially penetrating the second through hole 6031 and the first through hole 606 corresponding to the second through hole 6031, and the plug 608 is used for limiting the slide bar 6041.

[0074] In the above scheme, after adjusting the position of the sliding bar 6041, the bolt 608 is sequentially inserted through the hole on the sliding arm 603 and the corresponding hole on the sliding bar 6041, thereby fixing the sliding bar 6041 at the current position, preventing the sliding bar 6041 from moving accidentally due to external force and other factors during the centering process, and ensuring the stability of the clamping part 604. The bolt 608 provides reliable limiting function for the sliding bar 6041. This simple and effective limiting method enhances the stability of the clamping part 604 during the centering operation, avoids the problem of inaccurate positioning of the workpiece caused by the change of the position of the sliding bar 6041, and improves the reliability of the centering adjustment.

[0075] Further, the indicating part 6051 is a pointer.

[0076] Further, it further comprises a fixed plate 609 arranged on the workpiece interface plate 5, and the two ends of the cross beam 601 are rotatably arranged on the fixed plate 609; and a baffle plate 610 arranged at the bottom of the fixed plate 609, the baffle plate 610 being used for limiting the cross beam 601.

[0077] In the above scheme, the two ends of the cross beam 601 are rotatably arranged on the fixed plate 609, ensuring the flexibility of rotation of the cross beam 601 within a certain range. The baffle plate 610 is arranged at the bottom of the fixed plate 609, and when the cross beam 601 is rotated to a certain angle, it will contact the baffle plate 610, thereby limiting the excessive rotation of the cross beam 601, ensuring the stability and safety of the centering adjusting part 6 within the normal working range. The fixed plate 609 provides a stable mounting base and rotating support for the cross beam 601, ensuring the normal work of the centering adjusting part 6. The limiting effect of the baffle plate 610 prevents the damage of the centering adjusting part 6 or the collision with the workpiece caused by the accidental excessive rotation of the cross beam 601, and improves the safety and reliability of the entire tool during the centering operation.
