Description

Technical Field

[0001] This utility model belongs to the field of forging shaft center hole machining technology, specifically a forging shaft center hole machining device. Background Technology

[0002] The machining of shaft forgings requires high surface precision. Before finishing, the center point of the shaft part needs to be determined and a center hole needs to be drilled to facilitate subsequent machining.

[0003] Existing forging shaft center hole machining devices typically use one end to clamp the forging shaft and the other end to drill the center hole. However, these devices require repeated adjustments to the forging shaft during clamping and fixing to align its center point with the drill bit's center point, ensuring the machined hole is located at the center of the forging shaft, which is inconvenient to operate. Summary of the Invention

[0004] The purpose of this invention is to provide a forging shaft center hole machining device that aligns the center point of the forging shaft with the center point of the drill bit while facilitating and quickly clamping and fixing the forging shaft.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forging shaft center hole machining device, including a worktable, with two left and right distributed support blocks fixedly connected to the upper end face of the worktable, a notch opened on the upper end face of the support block, a cavity opened inside the support block, and through holes communicating with the cavity being opened through the front and rear inner sidewalls of the notch, and two symmetrically distributed L-shaped rods slidably connected to the lower end of the cavity, with clamping blocks that match each other and extend into the through holes fixedly connected to the other ends of the two L-shaped rods;

[0006] The upper surface of the workbench is slidably connected to two movable plates distributed on the left and right and located on both sides of two support blocks. Each of the two movable plates has a mounting block fixedly connected to one of its opposite side walls. Each of the two mounting blocks has a drill bit rotatably connected to one of its opposite side walls. Each of the two mounting blocks has multiple evenly distributed elastic telescopic rods fixedly connected to one of its opposite side walls.

[0007] In order to drive the two L-shaped rods to move in opposite directions, as a preferred embodiment of the forging shaft center hole machining device of this utility model, the cavity is rotatably connected to a first bidirectional lead screw threaded to the two L-shaped rods, the outer wall of the first bidirectional lead screw is fixedly connected to a worm gear located between the two L-shaped rods, the cavity is rotatably connected to a worm gear meshing with the worm gear, and the lower end face of the support block is equipped with a first motor, the output end of the first motor being fixedly connected to the worm gear.

[0008] In order to drive the two moving plates to move in opposite directions, as a preferred embodiment of the forging shaft center hole processing device of this utility model, the upper end face of the worktable is provided with a sliding groove, and a second bidirectional lead screw is rotatably connected inside the sliding groove. The lower end faces of the two moving plates are fixedly connected with sliders threaded to the second bidirectional lead screw. A second motor is installed inside the worktable, and the output end of the second motor is fixedly connected to the second bidirectional lead screw.

[0009] In order to drive the two drill bits to rotate, as a preferred embodiment of the forging shaft center hole machining device of this utility model, a third motor is installed inside each of the two mounting blocks, and the output ends of the two third motors are respectively fixedly connected to the two drill bits.

[0010] In order to make the two L-shaped rods move smoothly, as a preferred embodiment of the forging shaft center hole machining device of this utility model, the lower ends of the two L-shaped rods are slidably connected to the lower end of the cavity through a limiting block and a limiting groove.

[0011] In order to make the center point of the forging shaft coincide with the center point between the two clamping slots, as a preferred embodiment of the forging shaft center hole machining device of this utility model, clamping slots are provided on the opposite side walls of the two clamping blocks.

[0012] In order to ensure that the center point of the forging shaft and the center point of the two drill bits are at the same height after clamping and fixing, as a preferred embodiment of the forging shaft center hole machining device of this utility model, the center point of the two drill bits is at the same height as the center point of the two clamping grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In use, the forging shaft is moved into the two notches. Then, two moving plates, together with two mounting blocks, drive multiple elastic telescopic rods to move. These rods push the forging shaft to the middle position between the two drill bits. Next, two L-shaped rods drive two clamping blocks to move, causing them to abut against the outer wall of the forging shaft and clamp it in place. Simultaneously, the forging shaft enters the two clamping slots, allowing the center point of the forging shaft to coincide with the center point between the two slots. Since the center points of the two drill bits and the two clamping slots are at the same height, the center points of the two drill bits and the center point of the forging shaft are at the same height. This facilitates quick and easy clamping and fixing of the forging shaft while aligning its center point with the center points of the two drill bits. Attached Figure Description

[0020] Please see Figures 1 to 3 A forging shaft center hole machining device includes a worktable 1. Two left and right distributed support blocks 2 are fixedly connected to the upper end face of the worktable 1. The upper end face of the support block 2 is provided with a notch 3. A cavity 4 is provided inside the support block 2. The front and rear inner side walls of the notch 3 are provided with through holes 5 communicating with the cavity 4. Two symmetrically distributed L-shaped rods 6 are slidably connected to the lower end of the cavity 4. The other end of the two L-shaped rods 6 is fixedly connected with a clamping block 7 that matches each other and extends into the through hole 5.

[0021] The upper surface of the workbench 1 is slidably connected to two movable plates 8 distributed on the left and right and located on both sides of the two support blocks 2. The opposite side walls of the two movable plates 8 are fixedly connected to mounting blocks 9. The opposite side walls of the two mounting blocks 9 are rotatably connected to drill bits 10. The opposite side walls of the two mounting blocks 9 are fixedly connected to multiple evenly distributed elastic telescopic rods 21.

[0022] In this embodiment: When in use, the forging shaft is moved into the two notches 3, and then the two moving plates 8 move in opposite directions. The two moving plates 8, together with the two mounting blocks 9, drive the multiple elastic telescopic rods 21 to move, so that the other ends of the multiple elastic telescopic rods 21 abut against the two ends of the forging shaft. Then the two moving plates 8 continue to move, and the forging shaft is pushed to move by the multiple elastic telescopic rods 21, so that the forging shaft moves to the middle position of the two drill bits 10.

[0023] Next, the two L-shaped rods 6 move in opposite directions, driving the two clamping blocks 7 to move, so that the two clamping blocks 7 abut against the outer wall of the forging shaft, clamping and fixing the forging shaft. At the same time, the forging shaft enters the two clamping grooves 20. The center point of the forging shaft coincides with the center point between the two clamping grooves 20. Since the center point of the two drill bits 10 is at the same height as the center point of the two clamping grooves 20, the center point of the two drill bits 10 is at the same height as the center point of the forging shaft, thus facilitating and quickly clamping and fixing the forging shaft while aligning the center point of the forging shaft with the center point of the two drill bits 10.

[0024] Then the two moving plates 8 continue to move, and the two moving plates 8 cooperate with the two mounting blocks 9 to squeeze the multiple elastic telescopic rods 21 to retract, so that the two drill bits 10 abut against the two ends of the forging shaft. Then the two drill bits 10 rotate, and the two drill bits 10 perform drilling operations on the two ends of the forging shaft.

[0025] As a technical optimization of this utility model, the cavity 4 is rotatably connected to a first bidirectional lead screw 11 that is threadedly connected to two L-shaped rods 6. The outer wall of the first bidirectional lead screw 11 is fixedly connected to a worm gear 12 located between the two L-shaped rods 6. The cavity 4 is rotatably connected to a worm 13 that meshes with the worm gear 12. The lower end face of the support block 2 is equipped with a first motor 14, and the output end of the first motor 14 is fixedly connected to the worm 13.

[0026] In this embodiment: the first motor 14 is started, the first motor 14 drives the worm 13 to rotate, the worm 13, together with the worm wheel 12, drives the first bidirectional lead screw 11 to rotate, and the first bidirectional lead screw 11 drives the two L-shaped rods 6 to move in opposite directions.

[0027] As a technical optimization of this utility model, a slide groove 15 is provided on the upper end face of the workbench 1. A second bidirectional lead screw 16 is rotatably connected inside the slide groove 15. The lower end faces of the two moving plates 8 are fixedly connected with sliders 17 that are threadedly connected to the second bidirectional lead screw 16. A second motor 18 is installed inside the workbench 1. The output end of the second motor 18 is fixedly connected to the second bidirectional lead screw 16.

[0028] In this embodiment: the second motor 18 is started, the second motor 18 drives the second bidirectional lead screw 16 to rotate, and the second bidirectional lead screw 16, together with the two sliders 17, drives the two moving plates 8 to move in opposite directions.

[0029] As a technical optimization of this utility model, a third motor 19 is installed inside each of the two mounting blocks 9, and the output ends of the two third motors 19 are respectively fixedly connected to the two drill bits 10.

[0030] In this embodiment: two third motors 19 are started, and the two third motors 19 drive the two drill bits 10 to rotate respectively.

[0031] As a technical optimization of this utility model, the lower ends of the two L-shaped rods 6 are slidably connected to the lower end of the cavity 4 through a limiting block and a limiting groove.

[0032] In this embodiment, the limiting block and the limiting groove can limit the two L-shaped rods 6 while allowing the two L-shaped rods 6 to move smoothly.

[0033] As a technical optimization of this utility model, clamping grooves 20 are provided on the opposite side walls of the two clamping blocks 7.

[0034] In this embodiment, the center point of the forging shaft can be made to coincide with the center point between the two clamping grooves 20 through the two clamping grooves 20.

[0035] As a technical optimization of this utility model, the center point of the two drill bits 10 is at the same height as the center point of the two clamping grooves 20.

[0036] In this embodiment, the center point of the two drill bits 10 is at the same height as the center point of the two clamping slots 20, which enables the center point of the forging shaft to be at the same height as the center point of the two drill bits 10 after clamping and fixing.

[0037] Working principle: When in use, the forging shaft is moved into the two notches 3, and then the second motor 18 is started. The second motor 18 drives the second bidirectional lead screw 16 to rotate. The second bidirectional lead screw 16, together with the two sliders 17, drives the two moving plates 8 to move in opposite directions. The two moving plates 8, together with the two mounting blocks 9, drive the multiple elastic telescopic rods 21 to move, so that the other ends of the multiple elastic telescopic rods 21 abut against the two ends of the forging shaft. Then the two moving plates 8 continue to move, and the multiple elastic telescopic rods 21 push the forging shaft to move, so that the forging shaft moves to the middle position of the two drill bits 10.

[0038] Then, the first motor 14 is started, which drives the worm gear 13 to rotate. The worm gear 13, in conjunction with the worm wheel 12, drives the first double-acting screw 11 to rotate. The first double-acting screw 11 drives the two L-shaped rods 6 to move in opposite directions. The two L-shaped rods 6 drive the two clamping blocks 7 to move, so that the two clamping blocks 7 abut against the outer wall of the forging shaft, clamping and fixing the forging shaft. At the same time, the forging shaft enters the two clamping grooves 20. The two clamping grooves 20 enable the center point of the forging shaft to coincide with the center point between the two clamping grooves 20. Since the center point of the two drill bits 10 is at the same height as the center point of the two clamping grooves 20, the center point of the two drill bits 10 and the center point of the forging shaft are at the same height, thus facilitating and quickly clamping and fixing the forging shaft while aligning the center point of the forging shaft with the center point of the two drill bits 10.

[0039] Then the two moving plates 8 continue to move, and the two moving plates 8 cooperate with the two mounting blocks 9 to squeeze the multiple elastic telescopic rods 21 to retract, so that the two drill bits 10 abut against the two ends of the forging shaft. Then the two third motors 19 are started, and the two third motors 19 drive the two drill bits 10 to rotate respectively, and drill holes at both ends of the forging shaft through the two drill bits 10.

[0040] The above are merely preferred embodiments of the present utility model and are 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.
