Technical Field
[0001] This utility model relates to the field of gear shaft technology, and in particular to a multi-station synchronous drilling and positioning device for gear shaft machining. Background Technology
[0002] During the gear shaft machining process, holes need to be drilled on the gear shaft to facilitate the installation of connecting devices.
[0003] Before drilling, the gear shafts need to be transported. When transported to the drilling station, the gear shafts need to be arranged in sequence so that the spacing between each gear shaft is the same and the direction of each gear shaft is unified. The existing transport and positioning device requires manual adjustment of the direction and spacing of the gear shafts before positioning and clamping the disordered gear shafts. This is inconvenient to operate and does not improve the efficiency of gear shaft positioning and processing. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-station synchronous drilling and positioning device for gear shaft machining.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A multi-station synchronous drilling and positioning device for gear shaft machining includes a column and a horizontal plate. A fixed platform is fixedly connected to the top of the column. A first sliding groove is formed on one side wall of the fixed platform. An electric slider is slidably connected in the first sliding groove. A fixed plate is fixedly connected to the side wall of the electric slider. A second sliding groove is formed on the side wall of the fixed plate away from the fixed platform. Three second sliders are slidably connected in the second sliding groove. A vertically arranged connecting column is fixedly connected to the side wall of the second slider. Two vertical third sliding grooves are formed on the bottom side wall of the connecting column. A horizontal plate is slidably connected in the two third sliding grooves. An adjustment mechanism including an arc-shaped stop bar is provided at the bottom of the horizontal plate.
[0007] A rotating rod is rotatably connected to the bottom center of the horizontal plate, and an extension plate is fixedly connected to the bottom end of the rotating rod. Arc-shaped stop bars are symmetrically arranged on both sides of the bottom end of the extension plate.
[0008] Preferably, auxiliary slide grooves are symmetrically provided on the top and bottom of the fixed platform near the first slide groove, and the top and bottom of the electric slider are slidably connected to the auxiliary slide grooves through grippers.
[0009] Preferably, the arc-shaped structure at the bottom of the arc-shaped stop bar is adapted to the side wall of the gear shaft, and the height of the arc-shaped structure is less than the diameter of the gear shaft.
[0010] Preferably, a motor is fixedly installed at the center of the top of the horizontal plate, and the output shaft of the motor is fixedly connected to the top of the rotating rod.
[0011] Preferably, a first electric telescopic rod is fixedly installed on the side wall of the connecting column above the third slide groove, and the telescopic end of the first electric telescopic rod is fixedly connected to the top of the horizontal plate.
[0012] Preferably, a mounting frame is provided on one side of the column, and a belt conveyor is installed on the top of the mounting frame.
[0013] Preferably, the top two sides of the mounting frame are fixedly connected with mutually symmetrical mounting plates, the opposite surfaces of the two mounting plates are movably connected with positioning plates, and two second electric telescopic rods are fixedly installed on the opposite back surfaces of the two mounting plates. The telescopic ends of the two second electric telescopic rods on the same mounting plate are fixedly connected to the side wall of the positioning plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention incorporates a second slider and an adjustment mechanism. The second slider can be adjusted according to the spacing of the subsequent drilling equipment, ensuring that the gear shaft, after being adjusted and positioned by the adjustment mechanism, can be accurately clamped and drilled by the drilling equipment. The adjustment mechanism can drive the extension plate to rotate via a motor, causing the arc-shaped stop bar to finally abut against both sides of the gear shaft and rotate until the gear shaft is perpendicular to the belt conveying direction. This facilitates accurate clamping of the gear shaft by the subsequent drilling equipment, reducing the problem of inaccurate positioning caused by manual placement that affects drilling.
[0016] This invention, by setting up positioning plates, allows the gear shaft, after its direction has been adjusted by the adjustment mechanism, to be moved to the center of the belt conveyor by extending the second electric telescopic rod and pushing the two positioning plates to move towards each other. Combined with the restriction of the arc-shaped stop bar, the gear shaft spacing, direction, and position are effectively positioned, facilitating subsequent drilling operations.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-5 A multi-station synchronous drilling and positioning device for gear shaft machining includes a column 1 and a horizontal plate 11. A fixed platform 2 is fixedly connected to the top of the column 1. A first slide groove 3 is opened on one side wall of the fixed platform 2. An electric slider 5 is slidably connected in the first slide groove 3. A fixed plate 6 is fixedly connected to the side wall of the electric slider 5. A second slide groove 7 is opened on the side wall of the fixed plate 6 away from the fixed platform 2. Three second sliders 8 are slidably connected in the second slide groove 7. A vertically arranged connecting column 9 is fixedly connected to the side wall of the second slider 8. A horizontal plate 11 is slidably connected in the two third slide grooves 10. An adjustment mechanism 12 including an arc-shaped stop bar 15 is provided at the bottom of the horizontal plate 11.
[0025] A rotating rod 13 is rotatably connected to the bottom center of the horizontal plate 11. An extension plate 14 is fixedly connected to the bottom end of the rotating rod 13. Arc-shaped stop bars 15 are symmetrically arranged on both sides of the bottom end of the extension plate 14. After being conveyed by the belt conveyor 19, the gear shafts require more time to be drilled at the subsequent drilling station. Therefore, the adjusting mechanism 12 has sufficient time to adjust. The electric slider 5 can drive the fixed plate 6 and the three sets of adjusting mechanisms 12 to move, so that the three sets of adjusting mechanisms 12 can adjust and center a group of six gear shafts in sequence. The second slider 8 can be adjusted according to the spacing of the subsequent drilling equipment, so that the gear shafts adjusted and positioned by the adjusting mechanism 12 can be accurately clamped and drilled by the drilling equipment. The adjusting mechanism 12 can drive the extension plate 14 to rotate through the motor 16, so that the arc-shaped stop bars 15 finally abut against the two side walls of the gear shaft and rotate until the gear shaft is perpendicular to the belt conveying direction, which facilitates the subsequent drilling equipment to accurately clamp the gear shaft and reduces the problem of inaccurate positioning caused by manual placement affecting drilling.
[0026] As a technical optimization of this utility model, auxiliary slide grooves 4 are symmetrically provided on the top and bottom sides of the fixed platform 2 near the first slide groove 3. The top and bottom of the electric slider 5 are slidably connected to the auxiliary slide grooves 4 via grippers. The auxiliary slide grooves 4 are used in conjunction with the first slide groove 3 to assist the electric slider 5 in moving stably, so that the adjustment mechanism 12 can be adjusted stably.
[0027] As a technical optimization of this utility model, the arc-shaped structure at the bottom of the arc-shaped stop 15 is adapted to the side wall of the gear shaft, and the height of the arc-shaped structure is less than the diameter of the gear shaft. The two arc-shaped stop 15 push the side walls of the gear shaft, and the direction of the disordered gear shaft in different directions can be adjusted by rotation.
[0028] As a technical optimization of this utility model, a motor 16 is fixedly installed at the center of the top of the horizontal plate 11, and the output shaft of the motor 16 is fixedly connected to the top of the rotating rod 13. The motor 16 can drive the rotating rod 13 to rotate, thereby driving the extension plate 14 to rotate.
[0029] As a technical optimization of this utility model, a first electric telescopic rod 17 is fixedly installed on the side wall of the connecting column 9 above the third slide groove 10. The telescopic end of the first electric telescopic rod 17 is fixedly connected to the top of the horizontal plate 11. The first electric telescopic rod 17 can drive the horizontal plate 11 to rise and fall along the third slide groove 10 by telescopic movement, which in turn drives the arc-shaped stop bar 15 to rise and fall.
[0030] As a technical optimization of this utility model, a mounting frame 18 is provided on the lower side of one side of the column 1, and a belt conveyor 19 is installed on the top of the mounting frame 18. The belt conveyor 19 can transport the gear shaft from the loading station to the adjustment mechanism 12, and after adjustment, move it to the subsequent drilling station.
[0031] As a technical optimization of this utility model, symmetrical mounting plates 20 are fixedly connected to both sides of the top of the mounting bracket 18. Positioning plates 22 are movably connected to the opposite surfaces of the two mounting plates 20. Two second electric telescopic rods 21 are fixedly mounted on the opposite sides of the two mounting plates 20. The telescopic ends of the two second electric telescopic rods 21 on the same mounting plate 20 are fixedly connected to the side wall of the positioning plate 22. Extending the second electric telescopic rods 21 pushes the two positioning plates 22 to move towards each other, thereby aligning the gear shaft after adjustment of the direction.
[0032] In use, the spacing between the three second sliders 8 is first adjusted according to the spacing between the multi-station drilling equipment in the subsequent drilling stations. After starting the belt conveyor 19, the gear shafts to be drilled are placed on the belt conveyor 19 in sequence. At this time, the direction of the gear shafts is not uniform and is not perpendicular to the conveying direction. The belt conveyor 19 stops when it conveys the gear shafts to the end of the fixed platform 2. At this time, there are a total of six gear shafts on the belt conveyor 19 below the fixed platform 2. The first electric telescopic rod 17 extends and pushes the horizontal plate 11 down along the third slide 10 to the bottom of the third slide 10. At this time, the adjusting mechanism 12 is in the ready state, that is, the extension plate 14 is parallel to the belt conveying direction. The two arc-shaped stop rods 15 are located on both sides of the gear shafts respectively. The motor 16 is started, and the motor 16 rotates to drive the extension plate 14. 4. Rotate so that the bottom arc structure of the two arc-shaped stop bars 15 abuts against the two sides of the gear shaft and finally rotates until the extension plate 14 is perpendicular to the belt conveying direction. Each of the second electric telescopic rods 21 extends and pushes the positioning plate 22, bringing them closer together and finally pushing the two ends of the gear shaft so that the gear shaft is located at the center of the belt conveyor 19. At this time, the second electric telescopic rod 21 retracts, the positioning plate 22 returns to the side wall of the mounting plate 20, the control motor 16 reverses, and drives the extension plate 14 to reset. The first electric telescopic rod 17 retracts and drives the horizontal plate 11 to rise to the top of the third slide 10. The electric slider 5 starts and drives the fixed plate 6 to move in the opposite direction of the belt conveying direction to one end of the first slide 3 and then stops. Repeat the above operation to adjust the direction and center the other three gear shafts. After adjustment, the electric slider 5 resets.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
