Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a horizontal rotary three-axis positioner. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. In welding, when parts are welded in batches, personnel need to place the parts into fixtures and remove them after welding. With the development of machine welding technology, such batch welding is now mostly done by robotic welding.

[0003] However, the existing fixture structure is relatively simple and cannot meet the displacement requirements of the workpiece. As a result, the workpiece is prone to displacement during loading, which affects the welding effect of the robot. In addition, loading and unloading require operation intervals, and the simultaneous use of multiple fixtures not only affects the loading difficulty but also increases the fixture cost. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a horizontal rotary three-axis positioning machine, which solves the problems of existing fixtures having relatively simple structures that cannot meet the positioning requirements of workpieces, causing workpieces to easily shift during loading, affecting the welding effect of the robot, and requiring operation intervals for loading and unloading. The simultaneous use of multiple fixtures not only increases the difficulty of loading but also increases the cost of fixtures.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a horizontal rotary three-axis positioning machine, including a horizontal connecting plate, a horizontal rotating shaft turntable is provided at the lower end of the horizontal connecting plate, a mounting base is fixedly installed at the lower end of the horizontal rotating shaft turntable, a left mounting plate is fixedly connected to the left end of the horizontal connecting plate, a right mounting plate is fixedly connected to the right end of the horizontal connecting plate, a first clamp seat and a second clamp seat are respectively provided at the front and rear ends of the left and right mounting plates, the two first clamp seats are respectively connected to the left mounting plate and the right mounting plate through a servo motor, and a steering guardrail is provided on the outer side of the surface of the left and right mounting plates;

A connecting shaft is provided inside the horizontal rotating shaft turntable. The upper end of the connecting shaft extends to the top of the horizontal rotating shaft turntable and is fixedly connected to the lower end of the horizontal connecting plate.

[0007] Preferably, a turbine is fixedly installed on the surface of the connecting shaft inside the horizontal rotating platform, and the turbine and the worm gear are meshed together.

[0008] Preferably, the two first clamping seats and the second clamping seats are staggered, and the two second clamping seats are rotatably connected by bearings and left mounting plates and right mounting plates, respectively. The inner sides of the surfaces of the first clamping seats and the second clamping seats are provided with workpiece grippers.

[0009] Preferably, a reducer body is provided between the front end of the first clamping seat and the left mounting plate, and an identical reducer body is provided between the rear end of the first clamping seat and the right mounting plate. The two reducer bodies are fixedly connected to the left mounting plate and the right mounting plate, respectively. The output end of the reducer body is fixedly connected to the first clamping seat, and the output end of the second servo motor is connected to the reducer body.

[0012] This utility model provides a horizontal rotary three-axis positioning machine. Compared with the prior art, it has the following advantages:

[0013] This horizontal rotary three-axis positioning machine features a horizontal rotating table, fixture seats, and two servo motors. Two fixture seats are provided for both the first and second positions, corresponding to each other, forming a dual-station structure on both sides between the two mounting plates. This dual-station design facilitates part loading and unloading, improving production efficiency. The servo motor drives the horizontal connecting plate to rotate horizontally, enabling switching between the two stations. One station feeds the workpiece into the robotic welding equipment for welding, while the other station, located on the outside, facilitates part loading and unloading. Simultaneously, the servo motor rotates the first fixture seat to adjust the workpiece's angle, preventing workpiece displacement. Operators can use a scale pointer and horizontal scale to confirm the workpiece is positioned at the correct angle, facilitating its rotation to the appropriate position and enhancing practicality.

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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a horizontal rotary three-axis positioning machine, including a horizontal connecting plate 1, a horizontal rotating shaft turntable 2 at the lower end of the horizontal connecting plate 1, a servo motor 21 at the left end of the horizontal rotating shaft turntable 2, the output end of the servo motor 21 being connected to a worm gear 22 via a reducer, a connecting shaft 23 inside the horizontal rotating shaft turntable 2, the upper end of the connecting shaft 23 extending above the horizontal rotating shaft turntable 2 and fixedly connected to the lower end of the horizontal connecting plate 1, a turbine 24 fixedly installed on the surface of the connecting shaft 23 on the inner side of the horizontal rotating shaft turntable 2, the turbine 24 meshing with the worm gear 22, the servo motor 21 driving the worm gear 22 to rotate, thereby enabling the turbine 24 to drive the connecting shaft 23 to rotate, driving the horizontal connecting plate 1 to rotate horizontally;

[0022] A mounting base 3 is fixedly installed at the lower end of the horizontal rotating shaft turntable 2. A left mounting plate 4 is fixedly connected to the left end of the transverse connecting plate 1, and a right mounting plate 5 is fixedly connected to the right end of the transverse connecting plate 1. A first clamping seat 6 and a second clamping seat 7 are respectively provided at the front and rear ends of the left and right mounting plates 4 and 5. The two first clamping seats 6 and 7 are staggered. The two second clamping seats 7 are rotatably connected to the left and right mounting plates 4 and 5 respectively via bearings. Workpiece grippers are provided on the inner sides of the surfaces of the first and second clamping seats 6 and 7. A reducer body 61 is provided between the front end of the first clamping seat 6 and the left mounting plate 4, and an identical reducer body 61 is provided between the rear end of the first clamping seat 6 and the right mounting plate 5. The two reducer bodies 61 are fixedly connected to the left and right mounting plates 4 and 5 respectively. The output end of the reducer body 61 is fixedly connected to the first clamping seat 6. The output end of the servo motor 8 is connected to the reducer body 61. The front end of the left mounting plate 4 and the rear end of the right mounting plate 5 are both fixedly mounted with scale pointers 41. The surface of the first clamping seat 6 is provided with a horizontal scale 62. The scale pointers 41 and the horizontal scale 62 are compatible. The two first clamping seats 6 and the second clamping seat 7 form a dual-station structure on both sides of the mounting plate. After the horizontal connecting plate 1 is turned horizontally, the two stations can be switched freely. One station sends the workpiece into the robot welding equipment for welding, while the other station is located on the outside for easy picking and loading. After the workpiece is loaded, both ends are clamped and fixed by the first clamping seat 6 and the second clamping seat 7 respectively. The first clamping seat 6 is rotated by the servo motor 8 to adjust the angle of the workpiece. When the workpiece needs to be kept horizontal, the operator can confirm whether the workpiece is horizontal by the indication of the scale pointers 41 and the horizontal scale 62.

[0023] Two first clamp seats 6 are connected to the left mounting plate 4 and the right mounting plate 5 respectively via servo motor 8. The outer surfaces of the left mounting plate 4 and the right mounting plate 5 are each provided with a steering guardrail 9. The steering guardrail 9 has an arc-shaped structure design. Both steering guardrails 9 are fixedly connected to the left mounting plate 4 and the right mounting plate 5 via connecting rods. The steering guardrails 9 on both sides can form a protection, so that when the mounting plate rotates, the steering guardrail 9 moves in a circular path on the outer side, increasing safety.

[0024] During operation, after the workpiece is loaded, both ends are clamped and fixed by the first clamp seat 6 and the second clamp seat 7 respectively. The first clamp seat 6 is rotated by the second servo motor 8 to adjust the angle of the workpiece. When the workpiece needs to be kept horizontal, the operator can confirm whether the workpiece is horizontal by the indication of the scale pointer 41 and the horizontal scale 62. The two first clamp seats 6 and the second clamp seat 7 form a dual-station structure on both sides of the mounting plate. The first servo motor 21 drives the worm gear 22 to rotate, which in turn drives the connecting shaft 23 to rotate, driving the transverse connecting plate 1 to rotate horizontally. This allows the two stations to be switched freely. One station sends the workpiece into the robotic welding equipment for welding, while the other station is located on the outside for easy picking and loading. At the same time, the turning guardrails 9 on both sides can provide protection, so that the turning guardrails 9 move in a circular path on the outside when the mounting plate is rotating, increasing safety.
