Description

Technical Field

[0001] This utility model relates to the field of lathe robot technology, specifically to a height-adjustable lathe robot. Background Technology

[0002] A lathe robot is an automated device installed on a CNC machine tool. It moves precisely in three or more axes (X, Y, Z) via a gantry structure to automatically load and unload workpieces. It consists of a control system, a drive unit, and clamping tools. It is widely used in metal processing, automotive parts production, and other fields. It can significantly improve processing efficiency and accuracy, reduce manual intervention, and is an important part of modern intelligent manufacturing.

[0003] In the prior art, Chinese Patent Publication No. CN220218509U discloses a lathe gantry robot, belonging to the field of marine propeller technology. It includes a base plate, a fixed housing, and a sliding block. A fixed sleeve is installed at the top of the base plate, and a connecting rod is provided inside the fixed sleeve. A gantry frame is installed at the top of the connecting rod, and a groove is formed inside the gantry frame. A sliding block is provided inside the groove, and a fixed rod is installed at the bottom of the sliding block. A mounting frame is installed at the bottom of the fixed rod, and a drive mechanism is installed inside the sliding block. A first motor body is installed on the side wall of one end of the groove, and a threaded hole is provided inside the sliding block. When the gear plate rotates, it can drive the connecting rod to rise and fall within the gear plate body via the sliding sleeve and the sliding rod, facilitating the adjustment of the gantry frame height by raising and lowering the connecting rod, thus facilitating operation by the operator.

[0004] However, in actual use, the above solution still has some shortcomings. The height adjustment of the robot relies on the meshing transmission between the gear body and the toothed disc body, and is lifted by a single connecting rod. After bearing a large load or long-term use, wear gaps are easily generated between the gear body and the toothed disc body, resulting in unstable transmission. Consequently, the gantry frame is prone to shaking during lifting and after positioning, resulting in insufficient stability and affecting the operating accuracy of the robot. Utility Model Content

[0005] The purpose of this invention is to provide a height-adjustable lathe robot to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A height-adjustable lathe robot includes a support column and a robot body. Height adjustment components are provided on both the left and right sides of the support column. Support plates are provided on the side of each height adjustment component away from the support column. There are two robot bodies, which are respectively fixedly installed on the top of the two support plates. A base plate is fixedly connected to the bottom of the support column. The height adjustment assembly includes a mounting plate, a drive mechanism, a transmission mechanism, a guide mechanism, and a connecting mechanism. The drive mechanism, transmission mechanism, and guide mechanism are all fixedly mounted via the mounting plate. The connecting mechanism is fixed to the transmission mechanism and the guide mechanism. The drive mechanism drives the transmission mechanism to move the connecting mechanism, thereby causing the support plate to move up and down. The guide mechanism limits the direction of movement of the transmission mechanism. The opposite sides of the two support plates are respectively fixed to the transmission mechanisms within the two height adjustment assemblies by fasteners.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the driving mechanism is a servo motor, the transmission mechanism is a ball screw pair, the guiding mechanism consists of two linear guide pairs symmetrically distributed front and back, the output shaft of the servo motor is connected to the screw in the ball screw pair via a coupling, the connecting mechanism is fixed to the nut of the ball screw pair via a nut seat, and the connecting mechanism is fixed to the moving end of the two linear guide pairs via fasteners.

[0009] Furthermore, the connecting mechanism includes a first connecting plate, a second connecting plate, a connecting column, and a fixing plate. The side of the first connecting plate away from the supporting column is U-shaped, and its inner wall fits against the outer wall of the supporting plate and is fixed by fasteners. The second connecting plate is fixed to the nut of the ball screw pair. A slot is provided in the first connecting plate. The connecting column is fixedly connected to the side of the second connecting plate near the supporting plate and passes through the slot and is fixed by fasteners. The fixing plate is hollow inside and matches the cross-sectional shape of the front and rear sides of the connecting column. The fixing plate is installed through the connecting column and is fixed to the second connecting plate and the connecting column by fasteners.

[0010] Furthermore, support components are provided on both the left and right sides of the support column. Each support component includes a dual-axis cylinder and a support frame. The lifting end of the dual-axis cylinder is fixed to the bottom of the support frame, and the top of the support frame is attached to the bottom of the support plate.

[0011] Furthermore, diagonal braces are provided on both the front and rear sides of the support column and between them and the base plate.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: The drive mechanism drives the transmission mechanism to work, and under the action of the guide mechanism, the connecting mechanism connected to the transmission mechanism is limited to vertical up and down linear motion. The support plate is driven to move up and down through the connecting mechanisms on the left and right sides, so that the robot body moves up and down, ensuring the stability of the robot body during the up and down movement. The transmission is smooth and the height can be adjusted according to the lathes on the left and right sides. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-5 As shown, this utility model provides a height-adjustable lathe robot, including a support column 1 and a robot body 2. Height adjustment components 3 are provided on both the left and right sides of the support column 1. Support plates 4 are provided on the side of the two height adjustment components 3 away from the support column 1. There are two robot bodies 2, which are respectively fixedly installed on the top of the two support plates 4. A base plate 5 is fixedly connected to the bottom of the support column 1. The height adjustment assembly 3 includes a mounting plate 301, a drive mechanism, a transmission mechanism, a guide mechanism, and a connecting mechanism. The drive mechanism, transmission mechanism, and guide mechanism are all fixedly installed through the mounting plate 301. The connecting mechanism is fixed to the transmission mechanism and the guide mechanism. The drive mechanism is used to drive the transmission mechanism to drive the connecting mechanism, thereby causing the support plate 4 to move up and down. The guide mechanism is used to limit the direction of movement of the transmission mechanism. The opposite sides of the two support plates 4 are fixed to the transmission mechanisms within the two height adjustment components 3 by fasteners.

[0017] Each height adjustment component 3 uses a mounting plate 301 as its basic mounting platform. The drive mechanism, transmission mechanism, guide mechanism, and connecting mechanism are all fixedly installed with high precision through the mounting plate 301, together forming a height adjustment function. The drive mechanism serves as the power source, driving the transmission mechanism after startup. The core function of the transmission mechanism is to accurately and efficiently convert the rotational motion output by the drive mechanism into the required linear lifting motion. To ensure a smooth and wobbly lifting process, the guide mechanism works in conjunction with the transmission mechanism. Its core function is to strictly limit the movement direction of the transmission mechanism and the connecting mechanism it drives, so that it always maintains a precise vertical trajectory, while bearing the torque generated by lateral loads or off-center loads, ensuring the rigidity of the entire device during lifting and load-bearing processes. When the drive mechanism generates linear motion through the transmission mechanism, this motion is transmitted through the connecting mechanism. The support plate 4 is rigidly connected to the connecting mechanism through fasteners, thereby converting the linear motion of the connecting mechanism into the vertical lifting of the support plate 4 without loss, ultimately driving the robot body 2 fixed on its top to reach the precise target height.

[0018] The drive mechanism is a servo motor 302, the transmission mechanism is a ball screw pair 303, and the guide mechanism consists of two linear guide pairs 304, which are symmetrically distributed front and back. The output shaft of the servo motor 302 is connected to the screw in the ball screw pair 303 through a coupling. The connection mechanism is fixed to the nut of the ball screw pair 303 through a nut seat. The connection mechanism is fixed to the moving end of the two linear guide pairs 304 through fasteners.

[0019] With this configuration, the servo motor 302 serves as the power source during the height lifting process. Its core advantage lies in its ability to receive precise digital control signals and achieve precise control of speed, angle, and torque. The output shaft of the servo motor 302 is directly connected to the ball screw pair 303 via a coupling, so that the rotational motion of the output shaft of the servo motor 302 is transmitted to the ball screw pair 303 via the coupling. When the lead screw is driven to rotate by the servo motor 302, the rotational motion of the lead screw is efficiently and with low friction converted into the precise linear motion of the nut by the rolling of the balls between the lead screw and the nut, so that the subsequent robot body can realize lifting and lowering motion. The guiding mechanism consists of two linear guide rail pairs 304, which are symmetrically distributed front and back around the ball screw pair 303, thus forming a stable support structure. The connecting mechanism is rigidly fixed to the nut of the ball screw pair 303 through the nut seat. At the same time, the connecting mechanism is also fixed to the moving ends of the two linear guide rail pairs 304 through fasteners. This allows the connecting mechanism, the nut seat, and the moving ends of the two linear guide pairs 304 to be connected into a motion platform. When the nut of the ball screw pair 303 moves linearly, it drives the platform to move, and the motion trajectory of the platform is strictly constrained by the two symmetrically distributed linear guide pairs 304.

[0020] The connecting mechanism includes a first connecting plate 305, a second connecting plate 306, a connecting column 307, and a fixing plate 308. The side of the first connecting plate 305 away from the supporting column 1 is U-shaped, and its inner wall fits against the outer wall of the supporting plate 4 and is fixed by fasteners. The second connecting plate 306 is fixed to the nut of the ball screw pair 303. A slot 309 is provided in the first connecting plate 305. The connecting column 307 is fixedly connected to the side of the second connecting plate 306 near the supporting plate 4 and passes through the slot 309 and is fixed by fasteners. The fixing plate 308 is hollow inside and matches the cross-sectional shape of the front and rear sides of the connecting column 307. The fixing plate 308 is installed through the connecting column 307 and is fixed to the second connecting plate 306 and the connecting column 307 by fasteners.

[0021] In this configuration, the first connecting plate 305 is first connected and fixed to the support plate 4. Then, through the cooperation of the connecting column 307 and the first connecting plate 305, a stable connection is formed between the first connecting plate 305, the support plate 4, and the second connecting plate 306. In addition, the fixing plate 308 improves the support effect of the connecting column 307 during use. Furthermore, the connection mechanism is divided into multiple parts, which facilitates subsequent disassembly and maintenance. This allows the connecting mechanism to drive the support plate 4 to move up and down.

[0022] Among them, support components 6 are provided on both the left and right sides of the support column 1. The support components 6 include a dual-axis cylinder 601 and a support frame 602. The lifting end of the dual-axis cylinder 601 is fixed to the bottom of the support frame 602, and the top of the support frame 602 is attached to the bottom of the support plate 4.

[0023] This configuration makes the support frame 602 a precisely controllable lifting unit, but its core function is not to provide the main lifting driving force, but to be used as a stable support to ensure the stability of the support plate 4 during use, thereby facilitating the operation of the robot body 2. When the servo motor 302 starts and the support plate 4 begins to rise and fall, the dual-axis cylinder 601 always maintains a constant and precisely calculated air pressure through the external air circuit system. The upward lifting force generated by this air pressure ensures that the top of the support frame 602 is always in close contact with the bottom surface of the support plate 4. This makes the lifting and falling of the robot body 2 very stable and reduces the impact of instantaneous shock and vibration during the lifting and falling process. When rising, the support plate 4 moves upward, and under the action of constant pressure gas inside the dual-axis cylinder 601, its piston rod can smoothly extend synchronously, pushing the support frame 602 to follow the support plate 4 and maintain a stable support effect. When falling, the support plate 4 moves downward and presses against the support frame 602. At this time, the gas inside the dual-axis cylinder 601 is compressed, and the piston rod retracts smoothly under controlled conditions. By adjusting the throttle valve in the air circuit, its retraction speed can be precisely controlled to ensure the stability of the support plate 4 during the up and down movement.

[0024] Among them, diagonal braces 7 are provided between the front and rear sides of the support column 1 and the base plate 5.

[0025] This configuration uses two diagonal braces 7 to provide lateral support and enhance stability for the support column 1.
