Description

Technical Field

[0001] This utility model relates to the field of turning table technology, specifically a turning table with adjustable height. Background Technology

[0002] A turning rotary table is an important component of a CNC machine tool, mainly used for rotating and positioning the workpiece during turning operations. It can transform a traditional three-axis machining center into a four- or five-axis machining center, allowing multiple surfaces to be machined in a single setup. This avoids accuracy errors caused by repeated clamping, improving machining efficiency and precision. Traditional turning rotary tables are mostly fixed inside the machining center and cannot adjust the height of the workpiece, making them inflexible in use. To improve this, a turning rotary table with easily adjustable height is proposed.

[0003] As disclosed in the authorization announcement number CN213003760U, a four-station turntable with adjustable height includes a support base plate. The support base plate is generally circular in shape. The four-station turntable is provided on the upper surface of the support base plate. Four cavities are opened on the periphery of the support base plate. A movable push block is provided inside the cavity. A lifting block is provided on the top of the movable push block. Four gear grooves extending into the cavity are opened on the upper surface of the support base plate. A gear column is fixedly connected to the upper surface of the lifting block. The top of the gear column extends out of the upper surface of the support base plate through the gear groove and is fixedly connected to the turntable.

[0004] Although it realizes a four-station turntable with easy height adjustment, it solves the problem that the height of the turntable needs to be different for different workpiece sizes and models during workpiece processing, and the existing turntable height adjustment device has a complicated structure and is cumbersome to operate.

[0005] However, it does not solve the problem that existing turning tables are not conducive to centering and fixing workpieces, nor to flexibly adjusting the position and angle of workpieces in the horizontal and vertical directions, nor to adjusting the height of workpieces and performing flexible machining operations, thus affecting the flexibility of workpiece machining. Utility Model Content

[0006] The purpose of this utility model is to provide a turning table with adjustable height, so as to solve the problems mentioned in the background art, which are that turning tables are not convenient for center clamping and fixing workpieces, and for flexibly adjusting the position and angle of workpieces in the horizontal and vertical directions, which is not conducive to adjusting the height of workpieces and performing flexible machining operations, thus affecting the flexibility of workpiece machining.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a turning table with adjustable height, comprising a base and a first hydraulic cylinder. The first hydraulic cylinder is symmetrically arranged at the top of the base. A first push arm is installed at the output end of each of the first hydraulic cylinders. A bearing block is installed at the top of each of the first push arms. An adjustment plate is arranged above the base. A connecting shaft is provided at both ends of the adjustment plate, and the adjustment plate is movably connected to the bearing block through the connecting shaft. A servo motor is arranged on the outer wall of a set of bearing blocks. A first worm gear is installed at the output end of the servo motor, and the first worm gear is movably connected to the bearing block. A first worm wheel is fitted on the surface of the connecting shaft on one side of the first worm gear, and the first worm wheel meshes with the first worm gear.

[0008] Preferably, a drive seat is provided at the center of the bottom end of the adjustment plate, and a stepper motor is provided on the side wall of the drive seat.

[0009] Preferably, a second worm gear is installed at the output end of the stepper motor, and the second worm gear is movably connected to the drive seat.

[0010] Preferably, a movable shaft is movably mounted inside the drive seat on one side of the second worm gear, and the movable shaft extends to the outside of the adjustment plate and is movably connected to the adjustment plate.

[0011] Preferably, a second worm wheel is fitted onto the movable shaft surface on one side of the second worm, and the second worm wheel meshes with the second worm.

[0012] Preferably, a placement seat is installed at the top of the movable shaft, and three sets of electric push rods with equal spacing are provided on the outer wall of the placement seat.

[0013] Preferably, the output end of each electric push rod is equipped with a second push arm, and the second push arm is slidably connected to the placement seat.

[0014] Preferably, a clamping block is provided at the end of the second push arm away from the electric push rod, and the clamping block is fixedly connected to the second push arm.

[0015] Compared with the prior art, the beneficial effects of this utility model are: this turning table not only realizes the center clamping and fixing of the workpiece and the flexible adjustment of the workpiece's position and angle in the horizontal and vertical directions, facilitating the adjustment of the workpiece height and the flexible machining operation, but also improves the flexibility of workpiece machining.

[0016] (1) Install the device in the machining center, insert the cylindrical workpiece into the placement seat, drive the second push arm to move by the electric push rod, and drive the clamping block to move so that the clamping block contacts the outer wall of the workpiece. The three sets of electric push rods are controlled by PLC. The electric push rods are started simultaneously by controlling the relevant program. The movement distance of the second push arm is equal, so the cylindrical workpiece can be clamped in the center. Then, the machining center can be operated to complete the turning process of the workpiece. When it is necessary to adjust the height of the workpiece, the first hydraulic cylinder drives the first push arm to move upward. The first push arm drives the bearing block, adjusting plate, placement seat and workpiece to move upward to adjust the height of the workpiece, so as to facilitate turning of different positions of the workpiece. The workpiece is clamped and fixed in the center, which facilitates the adjustment of the workpiece height.

[0017] (2) The first worm is driven to rotate by the servo motor, and the first worm drives a set of connecting shafts to rotate through the first worm wheel. The connecting shaft drives the adjustment plate to rotate, and the adjustment plate drives the placement seat and the workpiece to rotate, so as to adjust the angle of the workpiece. When the workpiece needs to be rotated, the second worm is driven to rotate by the stepper motor, and the second worm drives the movable shaft to rotate through the second worm wheel. The movable shaft drives the placement seat and the workpiece to rotate in a circle. With the cooperation of the servo motor, the angle of the workpiece can be flexibly adjusted, so as to better process the workpiece. The position and angle of the workpiece can be flexibly adjusted in the horizontal and vertical directions, which facilitates the flexible processing of the workpiece and improves the flexibility of workpiece processing.

[0027] Example 1

[0028] Please see Figure 1-5 The present invention provides an embodiment of a turning table with adjustable height, comprising a base 1 and a first hydraulic cylinder 2. The first hydraulic cylinder 2 is symmetrically arranged at the top of the base 1 and serves as a power drive. The output end of each first hydraulic cylinder 2 is equipped with a first push arm 3, and the top of each first push arm 3 is equipped with a bearing block 4. An adjustment plate 5 is arranged above the base 1. Both ends of the adjustment plate 5 are equipped with connecting shafts 8, and the adjustment plate 5 is movably connected to the bearing block 4 through the connecting shafts 8. A servo motor 10 is arranged on the outer wall of a set of bearing blocks 4 and serves as a power drive. The output end of the servo motor 10 is equipped with a first worm gear 7, and the first worm gear 7 is movably connected to the bearing block 4. A first worm wheel 9 is fitted on the surface of the connecting shaft 8 on one side of the first worm gear 7, and the first worm wheel 9 meshes with the first worm gear 7.

[0029] The device is installed inside the machining center. The cylindrical workpiece is inserted into the placement seat 6. The electric push rod 17 is turned on, which drives the second push arm 18 to move. The second push arm 18 then drives the clamping block 11 to move, so that the clamping block 11 contacts the outer wall of the workpiece. The three sets of electric push rods 17 are controlled by PLC. The electric push rods 17 are started simultaneously through relevant programs. The movement distance of the second push arm 18 is equal, so the cylindrical workpiece can be clamped in the center. Then, the machining center can be operated to perform turning machining on the workpiece. When it is necessary to adjust the height of the workpiece, the first hydraulic cylinder 2 is turned on, which drives the first push arm 3 to move upward. The first push arm 3 then drives the bearing block 4, the adjusting plate 5, the placement seat 6, and the workpiece to move upward, thereby adjusting the height of the workpiece. This facilitates turning machining on different positions of the workpiece, realizing the center clamping and fixing of the workpiece and facilitating the adjustment of the workpiece height.

[0030] A drive base 13 is provided at the center of the bottom of the adjustment plate 5, and a stepper motor 16 is provided on the side wall of the drive base 13. The stepper motor 16 plays the role of power drive.

[0031] The output end of the stepper motor 16 is equipped with a second worm gear 15, and the second worm gear 15 is movably connected to the drive base 13;

[0032] A movable shaft 12 is movably installed inside the drive seat 13 on one side of the second worm gear 15, and the movable shaft 12 extends to the outside of the adjustment plate 5 and is movably connected to the adjustment plate 5.

[0033] The surface of the movable shaft 12 on one side of the second worm 15 is fitted with a second worm wheel 14, and the second worm wheel 14 meshes with the second worm 15. The top of the movable shaft 12 is equipped with a placement seat 6, and three sets of electric push rods 17 with equal spacing are provided on the outer wall of the placement seat 6. The electric push rods 17 play a power driving role.

[0034] The output end of each electric push rod 17 is equipped with a second push arm 18, and the second push arm 18 is slidably connected to the placement seat 6.

[0035] The second push arm 18 is provided with a clamping block 11 at the end away from the electric push rod 17, and the clamping block 11 is fixedly connected to the second push arm 18.

[0036] When the workpiece angle needs to be adjusted, the servo motor 10 is turned on, driving the first worm 7 to rotate. The first worm 7 meshes with the first worm wheel 9, driving a set of connecting shafts 8 to rotate via the first worm wheel 9. With the movable cooperation of the connecting shafts 8 and the bearing block 4, the connecting shafts 8 drive the adjusting plate 5 to rotate, which in turn drives the placement seat 6 and the workpiece to rotate, thus adjusting the workpiece angle. When the workpiece needs to be rotated, the stepper motor 16 is turned on, driving the second worm 15 to rotate. The second worm 15 meshes with the second worm wheel 14, driving the movable shaft 12 to rotate via the second worm wheel 14. The movable shaft 12 then drives the placement seat 6 and the workpiece to rotate in a circular motion. With the cooperation of the servo motor 10, the workpiece angle can be flexibly adjusted, allowing for better workpiece processing. This achieves flexible horizontal and vertical adjustment of the workpiece's position and angle, facilitating flexible workpiece processing and improving the flexibility of workpiece processing.

[0037] Working principle: The device is installed inside the machining center. A cylindrical workpiece is inserted into the placement seat 6. An electric push rod 17 drives the second push arm 18 to move, which in turn moves the clamping block 11, bringing it into contact with the outer wall of the workpiece. The three sets of electric push rods 17 are controlled by a PLC, and the push rods 17 start simultaneously through a relevant program. The second push arm 18 moves the same distance, thus centrally clamping the cylindrical workpiece. The machining center then performs turning operations on the workpiece. When the workpiece height needs to be adjusted, the first hydraulic cylinder 2 drives the first push arm 3 upwards, which in turn moves the bearing block 4, adjusting plate 5, placement seat 6, and workpiece upwards to adjust the workpiece height. When adjusting the workpiece angle, the servo motor 10 drives the first worm gear 7 to rotate, which in turn drives a set of connecting shafts 8 to rotate via the first worm wheel 9. With the movable cooperation between the connecting shafts 8 and the bearing block 4, the connecting shafts 8 drive the adjusting plate 5 to rotate, which in turn drives the placement seat 6 and the workpiece to rotate, thereby adjusting the workpiece angle. When the workpiece needs to be rotated, the stepper motor 16 drives the second worm gear 15 to rotate, which in turn drives the movable shaft 12 to rotate via the second worm wheel 14. The movable shaft 12 drives the placement seat 6 and the workpiece to rotate in a circular motion. With the cooperation of the servo motor 10, the angle of the workpiece can be flexibly adjusted, thereby enabling better processing of the workpiece. The above is the complete usage of the height-adjustable turning rotary table.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
