Description

A drilling device for gear production Technical Field

[0001] This utility model relates to the field of gear manufacturing technology, and in particular to a drilling device for gear manufacturing. Background Technology

[0002] As a widely used mechanical transmission component in modern machinery, gears involve several key processes in their production, which directly affect their precision, reliability, and service life. Among these processes, drilling is required to improve gear heat dissipation and reduce gear weight, thus necessitating the use of a drilling device.

[0003] However, existing technologies have some problems: existing gear production drilling devices usually fix the gear directly to the worktable by means of a clamp for drilling. However, existing devices lack a positioning structure and require multiple calibrations of the gear. At the same time, existing devices cannot guarantee whether the gear moves during drilling, resulting in low drilling accuracy. Therefore, we propose a gear production drilling device. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a drilling device for gear production. The device uses a positioning rod to position the gear and a limiting rod to limit the gear, thereby ensuring the gear is accurately fixed and avoiding deviations in the drilling position.

[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. 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.

[0024] As shown in Figures 1 to 5, the present invention provides a drilling device for gear production, including a base 1. The base 1 is a cuboid and is made of multiple sets of stainless steel plates welded together. The main function of the base 1 is to support the entire device and ensure its stable operation.

[0025] Furthermore, a fixed platform 2 is fixedly connected to the base 1, a positioning rod 3 is slidably connected to the fixed platform 2, and an adjustment component 4 is provided on the fixed platform 2. The adjustment component 4 is used to adjust the positioning rod 3. The adjustment component 4 includes an adjustment block 41. An adjustment groove is provided on the fixed platform 2, the adjustment block 41 is slidably connected in the adjustment groove, the positioning rod 3 is fixedly connected to the adjustment block 41, and a rack 42 is fixedly connected to the adjustment block 41.

[0026] Furthermore, the adjustment assembly 4 also includes a first motor 44, which is fixedly connected to the fixed platform 2. The output end of the first motor 44 is keyed to the adjustment gear 43, which meshes with the rack 42.

[0027] Specifically, the first motor 44 starts and drives the adjusting gear 43 to rotate. After the adjusting gear 43 rotates, it will drive the rack 42 to move, thereby causing the adjusting block 41 to slide in the adjusting groove on the fixed platform 2. The adjusting block 41 then drives the positioning rod 3 to move, so that the two sets of positioning rods 3 fit against the inner wall of the gear's central inner hole, thereby positioning the gear and ensuring accurate drilling position.

[0028] Furthermore, a sliding groove is provided on the base 1, and two sets of fixing clamps 5 are slidably connected in the sliding groove. A drive assembly 6 is provided in the base 1. The drive assembly 6 is used to drive the fixing clamps 5 to slide. The drive assembly 6 includes a bidirectional lead screw 61, which is rotatably connected in the sliding groove. The two sets of fixing clamps 5 are respectively threaded to both ends of the bidirectional lead screw 61.

[0029] Furthermore, the drive assembly 6 also includes a second motor 62, the output end of which is connected to a worm gear 63 via a coupling, and a worm wheel 64 is fixedly connected to one end of a bidirectional lead screw 61, with the worm gear 63 meshing with the worm wheel 64.

[0030] Specifically, the second motor 62 starts and drives the worm gear 63 to rotate, which in turn drives the worm wheel 64 to rotate. This causes the fixed clamp 5 to slide in the groove of the base 1 through the threaded engagement, thereby fixing the gear between the two sets of fixed clamps 5.

[0031] Furthermore, a limiting rod 7 is movably connected to the base 1, a slide is provided on the base 1, a connecting platform 10 is connected to the slide within the slide, a first hydraulic rod 11 is fixedly connected to the base 1, the connecting platform 10 is fixedly connected to the movable end of the first hydraulic rod 11, the limiting rod 7 is fixedly connected to the connecting platform 10, and an avoidance hole is provided on the fixing clamp 5, the fixing clamp 5 is provided through the avoidance hole.

[0032] Specifically, after the fixed clamp 5 fixes the gear, the first hydraulic rod 11 extends and retracts, causing the connecting platform 10 to slide in the slide of the base 1, thereby causing the limiting rod 7 to move. This allows the limiting rod 7 to pass through the clearance hole of the fixed clamp 5 and engage between the gear teeth, further fixing the gear and preventing the gear from rotating during the drilling process, which would affect the drilling accuracy.

[0033] Furthermore, a support arm 8 is fixedly connected to the base 1, a second hydraulic rod 13 is fixedly connected to the support arm 8, a movable plate 12 is fixedly connected to the second hydraulic rod 13, and a punching assembly 9 is provided on the movable plate 12.

[0034] Furthermore, the drilling assembly 9 includes a moving stage 91, a groove is provided on the movable plate 12, the moving stage 91 is slidably connected in the groove, a threaded rod 92 is rotatably connected in the groove, the threaded rod 92 is threadedly connected to the moving stage 91, a third motor 93 is fixedly connected on the movable plate 12, and the threaded rod 92 is keyed to the output end of the third motor 93.

[0035] Specifically, after the third motor 93 starts, it drives the threaded rod 92 to rotate. After the threaded rod 92 rotates, it drives the moving table 91 to slide in the groove of the movable plate 12, thereby changing the position of the movable plate 12, which is to say, changing the position of the drill bit 96, so that the drill bit 96 moves to the gear drilling position.

[0036] Furthermore, a fourth motor 94 is fixedly connected to the moving platform 91, and a connector 95 is keyed to the output end of the fourth motor 94. A drill bit 96 is fixedly connected to the connector 95.

[0037] Specifically, the second hydraulic rod 13 extends and retracts to move the movable plate 12, thereby changing the height of the movable plate 12, which in turn changes the height of the drill bit 96, allowing the drill bit 96 to drill holes in the gear. At the same time, the fourth motor 94 starts to drive the connector 95 and the drill bit 96 to rotate and drill holes in the gear.

[0038] The working principle of this utility model is as follows:

[0039] This utility model is equipped with a positioning rod 3 and an adjustment component 4. The first motor 44 starts and drives the adjustment gear 43 to rotate. After the adjustment gear 43 rotates, it will drive the rack 42 to move, thereby driving the adjustment block 41 to slide in the adjustment groove on the fixed platform 2. The adjustment block 41 then drives the positioning rod 3 to move, so that the two sets of positioning rods 3 fit against the inner wall of the gear's central inner hole, thereby positioning the gear and ensuring accurate drilling position.

[0040] This utility model is equipped with a limiting rod 7. After the gear is fixed by the fixing clamp 5, the first hydraulic rod 11 extends and retracts to drive the connecting platform 10 to slide in the slide of the base 1, thereby driving the limiting rod 7 to move. This allows the limiting rod 7 to pass through the clearance hole of the fixing clamp 5 and engage between the teeth of the gear, further fixing the gear and preventing the gear from rotating during the drilling process, which would affect the drilling accuracy.

[0041] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
