Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical loading and unloading technology, and in particular to a gantry-type loading and unloading mechanism for a CNC lathe with a sewing machine needle chuck. Background Technology
[0002] Trusses are widely used in machining and material handling processes in factories and construction sites. It is common practice to install robotic arms on trusses for material handling.
[0003] In the prior art, automatic loading and unloading devices for CNC lathes used for clamping and machining workpieces typically employ a rotary mechanical clamping structure. This structure utilizes the rotational motion at a fulcrum to grip the workpiece. During the gripping process, the acceleration generated by the gripper can cause impact at the hinge or gripper. To address this issue, application number 202223105424.3 discloses a gantry-type automatic loading and unloading device for CNC lathes, comprising a gantry assembly, a transverse movement assembly, a vertical movement assembly, a lower rotation assembly, and a workpiece clamping assembly. It includes two columns and a crossbeam vertically connected to the upper ends of the two columns. A lateral moving component is set on the crossbeam and can move left and right relative to the crossbeam. A vertical moving component is set on the lateral moving component and can move up and down relative to the lateral moving component. A lower rotating component is connected to the bottom end of the vertical moving component. A workpiece clamping component is connected to the bottom end of the lower rotating component. The lateral moving component includes a cylinder crossbeam connecting plate and a lateral driving mechanism that can drive the cylinder crossbeam connecting plate to slide left and right. The vertical moving component includes a circular guide rail, a circular guide rail connecting plate, a circular guide rail slider, a circular guide rail support plate, and a long cylinder.
[0004] However, a thorough reading of the aforementioned patent documents reveals the following shortcomings: the material handling robot on the lathe has a simple structure and a narrow range of applications. It only uses a motor to drive the clamping assembly to rotate half a revolution to pick up and place workpieces. As a result, the simple structure of the material handling robot on the lathe makes it inconvenient to pick up and place workpieces in different positions, and the mechanical material handling has a small stroke range, leaving room for improvement.
[0005] Therefore, this application proposes a gantry-type loading and unloading mechanism for a CNC lathe needle chuck of a sewing machine to solve the above problems. Utility Model Content

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a gantry-type loading and unloading mechanism for a CNC lathe needle chuck of a sewing machine, including a slide rail and an adjustment mechanism disposed above the CNC lathe;
[0008] A slider is slidably mounted on the slide rail, and a cylinder is mounted on the slider. An adjustment mechanism is provided at the output end of the cylinder.
[0009] The adjustment mechanism includes a U-shaped plate, a rotating shaft, a transmission plate, a base, a mounting seat, pneumatic clamps, and a second electric motor.

[0010] A further feature of this invention is that a second electric motor is fixedly installed on one side of the U-shaped plate, and the output end of the second electric motor is fixedly connected to one end of the rotating shaft. Driven by the second electric motor, the rotating shaft can rotate a certain angle on the U-shaped plate. At the same time, the rotating shaft is driven by the cooperation between the transmission plate, the base, and the mounting seat, causing the two pneumatic clamps to rotate a certain angle around the rotating shaft as the center, thereby achieving the effect of adjusting the tilt angle of the two pneumatic clamps, and thus achieving the effect of picking up and putting down the needle clamps in different positions.
[0011] A further feature of this invention is that the two pneumatic clamps are perpendicular to each other to avoid motion interference during the picking and placing of the needle clamp.

The output end of the motor is fixedly connected to the mounting seat. Driven by the motor, the mounting seat can rotate a certain angle on the base. At the same time, the mounting seat drives the two pneumatic clamps to rotate synchronously, thereby achieving the effect of alternately aligning the two pneumatic clamps with the placement plate and material rack on the CNC lathe, thus facilitating the two pneumatic clamps to pick up and put down the needle chuck.
[0013] A further feature of this invention is that a bearing is fixedly sleeved on the mounting base, and the outer wall of the bearing is fixedly connected to the base to facilitate the rotation of the mounting base.
[0014] A further feature of this invention is that both ends of the slide rail are fixedly connected to support legs for support.

A motor is fixedly mounted on one side of one of the two support legs, and the output end of the motor is fixedly connected to one end of the threaded rod. Driven by the motor, the threaded rod can rotate on the two support legs and perform threaded transmission with the slider. This allows the slider to drive the two pneumatic clamps to move horizontally through the transmission of the cylinder, thereby further facilitating the picking and placing of the needle clamp.
[0016] A further feature of this invention is that: bearings are fixedly sleeved at both ends of the threaded rod, and the outer walls of the two bearings are respectively fixedly connected to the two support legs to facilitate the rotation of the threaded rod.

[0027] Reference Figures 1-4 A gantry-type loading and unloading mechanism for a CNC lathe needle chuck of a sewing machine includes a slide rail 1 and an adjustment mechanism 4 mounted above the CNC lathe.
[0028] A slider 2 is slidably mounted on the slide rail 1, and a cylinder 3 is mounted on the slider 2. An adjustment mechanism 4 is provided at the output end of the cylinder 3.
[0029] The adjustment mechanism 4 includes a U-shaped plate 41, a rotating shaft 42, a transmission plate 43, a base 44, a mounting seat 45, pneumatic clamps 46, and a second electric motor 47. The output end of the cylinder 3 is fixedly mounted with the U-shaped plate 41. The rotating shaft 42 is rotatably connected to the U-shaped plate 41. The transmission plate 43 is fixedly connected to the rotating shaft 42. The base 44 is fixedly mounted at one end of the transmission plate 43. The mounting seat 45 is rotatably connected to the bottom of the base 44. Pneumatic clamps 46 are fixedly mounted on both sides of the mounting seat 45. Each of the two pneumatic clamps 46 holds and fixes a needle chuck 8. Through the coordinated design between the slide rail 1, the threaded rod 7, the first electric motor 6, the cylinder 3, and the adjustment mechanism 4, the two pneumatic clamps 46 can be appropriately adjusted according to the actual situation, thereby achieving the effect of conveniently picking up and putting down needle chucks 8 in different positions, greatly improving convenience and flexibility.
[0030] In this embodiment, a second motor 47 is fixedly installed on one side of the U-shaped plate 41. The output end of the second motor 47 is fixedly connected to one end of the rotating shaft 42. Driven by the second motor 47, the rotating shaft 42 can rotate on the U-shaped plate 41 at a certain angle. At the same time, the rotating shaft 42 is driven by the transmission plate 43, the base 44 and the mounting base 45, so that the two pneumatic clamps 46 rotate around the rotating shaft 42 at a certain angle, thereby achieving the effect of adjusting the tilt angle of the two pneumatic clamps 46, and thus achieving the effect of picking up and putting down the needle clamps 8 in different positions.
[0031] In this embodiment, the two pneumatic clamps 46 are perpendicular to each other to avoid motion interference during the picking and placing of the needle chuck 8. The pneumatic clamp 46 includes a connecting plate, a clamping cylinder, an opening and closing gripper, a slider, and an outer housing. The two clamping cylinders are respectively installed on opposite sides of the upper surface of the connecting plate. The two sets of opening and closing grippers are respectively connected to the two clamping cylinders, and the opening and closing grippers are controlled by the corresponding clamping cylinders to open or close, thereby achieving the effect of clamping and fixing the needle chuck 8. The specific structure and working principle of the pneumatic clamp 46 can be referred to the document with application number 202223105424.3 filed in this application, which is prior art and will not be described in detail.
[0032] In this embodiment, a mounting groove is provided on the base 44, and a mounting seat 45 is installed in the mounting groove. A motor 3 is fixedly installed in the mounting groove, and the output end of the motor 3 is fixedly connected to the mounting seat 45. Driven by the motor 3, the mounting seat 45 can rotate on the base 44 at a certain angle. At the same time, the mounting seat 45 drives two pneumatic clamps 46 to rotate synchronously, thereby achieving the effect of alternately aligning the two pneumatic clamps 46 with the placement plate and material rack on the CNC lathe, thus facilitating the two pneumatic clamps 46 to pick up and put down the needle chuck 8.
[0033] In this embodiment, a bearing is fixedly sleeved on the mounting base 45, and the outer wall of the bearing is fixedly connected to the base 44 to facilitate the rotation of the mounting base 45.
[0034] In this embodiment, both ends of the slide rail 1 are fixedly connected to support legs 5, which serve as supports.
[0035] In this embodiment, the same threaded rod 7 is rotatably connected to the two support legs 5. The threaded rod 7 is threadedly connected to the slider 2. A motor 6 is fixedly installed on one side of one of the two support legs 5. The output end of the motor 6 is fixedly connected to one end of the threaded rod 7. Driven by the motor 6, the threaded rod 7 can rotate on the two support legs 5 and perform threaded transmission with the slider 2. This allows the slider 2 to drive the two pneumatic clamps 46 to move horizontally through the transmission of the cylinder 3, thereby further facilitating the picking and placing of the needle chuck 8.
[0036] In this embodiment, bearings are fixedly sleeved at both ends of the threaded rod 7, and the outer walls of the two bearings are fixedly connected to the two support legs 5 respectively, so as to facilitate the rotation of the threaded rod 7.
[0037] In this embodiment, bearings are fixedly sleeved at both ends of the rotating shaft 42, and the outer walls of the two bearings are fixedly connected to the U-shaped plate 41, so that the rotating shaft 42 can rotate on the U-shaped plate 41.
[0038] Working principle: During use, the motor 6, cylinder 3, motor 47, pneumatic clamp 46 and motor 3 are driven and controlled by the preset program in the control module of the CNC lathe.
[0039] First, the mounting base 45 can be rotated at a certain angle on the base 44 by the drive of the electric motor 3. At the same time, the mounting base 45 drives the two pneumatic clamps 46 to rotate synchronously, so that the two pneumatic clamps 46 can be alternately aligned with the placement plate and material rack on the CNC lathe, thereby facilitating the two pneumatic clamps 46 to pick up and put away the needle chuck 8.
[0040] Meanwhile, the rotating shaft 42 can be rotated at a certain angle on the U-shaped plate 41 by the drive of the electric motor 47. At the same time, the rotating shaft 42 is driven by the transmission plate 43, the base 44 and the mounting base 45, so that the two pneumatic clamps 46 rotate at a certain angle around the rotating shaft 42, thereby achieving the effect of adjusting the tilt angle of the two pneumatic clamps 46, and thus achieving the effect of picking up and putting down the needle clamps 8 in different positions.
[0041] Driven by cylinder 3, the two pneumatic clamps 46 can move up and down, thereby further facilitating the picking and placing of needle chuck 8.
[0042] Driven by the electric motor 6, the threaded rod 7 rotates on the two support legs 5 and performs threaded transmission with the slider 2. This causes the slider 2 to drive the two pneumatic clamps 46 to move horizontally through the transmission of the cylinder 3, thereby further facilitating the picking and placing of the needle chuck 8.
[0043] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, the needle chuck 8 in different positions can be picked up and put down, improving convenience and flexibility, thereby increasing processing efficiency. Moreover, the structure is simple and more practical.
