Description

Technical Field

[0001] This utility model belongs to the field of parts drilling technology, specifically relating to a metal parts drilling and positioning device. Background Technology

[0002] Metal parts are a collective term for metal blocks, rods, tubes, etc., of various specifications and shapes manufactured from metal materials. When machining metal parts, it is often necessary to drill holes in their surfaces. However, drilling devices are prone to vibration during use, causing the metal parts to shift during machining and affecting the machining quality. Therefore, it is necessary to position the metal parts correctly.

[0003] The existing patent, CN220311829U, describes a metal parts drilling device. It includes a second rotating plate, a second threaded rod, clamping devices, a first rotating plate, a first threaded rod, and a rectangular plate. In use, the second rotating plate drives the second threaded rod to rotate, bringing the two clamping devices closer together and adjusting their distance. Subsequently, rotating the first rotating plate drives the first threaded rod to rotate, causing the rectangular plate to move downwards, thereby clamping the metal parts.

[0004] However, the above solution only clamps and positions the metal parts by moving the rectangular plate downwards. This method can only clamp and position the metal parts in the vertical direction and cannot clamp and position them in the horizontal direction. The limiting direction is relatively simple, which can easily cause the metal parts to shift horizontally during the processing, thus affecting the processing quality. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a metal part drilling and positioning device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A drilling and positioning device for metal parts includes a work frame, a connecting plate that is slidably and vertically positioned within the work frame, a driving mechanism for sliding the connecting plate within the work frame, and a drilling rig fixedly mounted at the bottom of the connecting plate; a worktable fixedly positioned within the work frame, two second toothed plates that are slidably and vertically positioned above the worktable, the two second toothed plates sliding towards or away from each other, and clamping plates connected to the facing sides of the two second toothed plates via first elastic elements, the two second toothed plates engaging with the connecting plate; and sleeves that are slidably and vertically positioned on the facing sides of the two clamping plates, the bottom of the sleeves connected to abutment plates via second elastic elements, the sleeves engaging with the second toothed plates.

[0008] Furthermore, the driving mechanism includes a first cylinder, which is fixedly mounted on the top of the work frame, and the telescopic shaft of the first cylinder is fixedly connected to the top of the connecting plate.

[0009] Furthermore, two first toothed plates are fixedly installed at both ends of the connecting plate in the vertical direction, and two first gears are rotatably installed on the working frame. The first gears mesh with the first toothed plates one-to-one and also mesh with the second toothed plates one-to-one.

[0010] Furthermore, the first elastic element includes a first telescopic rod, which is fixedly mounted on the second toothed plate. One end of the first telescopic rod is fixedly embedded in the second toothed plate, and the other end is fixedly connected to the clamping plate. A first spring is sleeved on the outer surface of the first telescopic rod. The first spring has the same telescopic direction as the first telescopic rod. One end of the first spring is fixedly connected to the second toothed plate, and the other end is fixedly connected to the clamping plate.

[0011] Furthermore, a third toothed plate is fixedly mounted on the top of the second toothed plate, and a second gear that meshes with and drives the third toothed plate is rotatably mounted on the top of the clamping plate. A lead screw is fixedly mounted coaxially on the bottom of the second gear. The number of lead screws and sleeves are equal and correspond one-to-one, and each lead screw is threadedly engaged with the corresponding sleeve.

[0012] Furthermore, the second elastic element includes a second telescopic rod, which is fixedly installed inside each sleeve. The top of the second telescopic rod is fixedly connected to the sleeve, and the bottom of the second telescopic rod is fixedly connected to the abutment plate. A second spring is sleeved on the outer surface of the second telescopic rod. The second spring has the same telescopic direction as the second telescopic rod. The top of the second spring is fixedly connected to the sleeve, and the bottom of the second spring is fixedly connected to the abutment plate.

[0013] This application has the following beneficial effects:

[0014] 1. As the drive mechanism moves the drill closer to the metal part, the two clamping plates automatically move closer to each other, thus clamping and positioning the metal part in the horizontal direction. At the same time, the two abutment plates automatically move closer to the metal part, thus clamping and limiting the metal part in the vertical direction. The limiting direction is more diverse, the limiting effect is better, and it prevents the metal part from shifting during processing, ensuring processing quality.

[0015] 2. By simply controlling the drilling rig to approach the metal part, the horizontal and vertical limiting of the metal part can be achieved by this solution. The overall transmission effect is better, and more drive sources are not required. This reduces the workload of the staff and the construction difficulty of the control system, resulting in better practical effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] like Figures 1-2 As shown, the technical solution adopted by this utility model is as follows: a metal part drilling and positioning device, including a work frame 1, a connecting plate 3 is slidably arranged in the vertical direction inside the work frame 1, a drill 4 is fixedly installed at the bottom of the connecting plate 3, the drill 4 is existing technology and will not be described in detail in this solution, and a driving mechanism for driving the connecting plate 3 to slide is provided on the work frame 1.

[0023] The drive mechanism includes a first cylinder 2, which is fixedly mounted on the top of the work frame 1, and the telescopic shaft of the first cylinder 2 is fixedly connected to the top of the connecting plate 3. A second cylinder 16 is fixedly mounted on the inner wall of the work frame 1, and the telescopic shaft of the second cylinder 16 is fixedly connected to a protective cover 17.

[0024] When the first cylinder 2 is activated, the telescopic shaft of the first cylinder 2 pushes the drill 4 toward the metal part via the connecting plate 3, so that the drill 4 passes through the protective cover 17 to drill holes in the metal part. The protective cover 17 can prevent metal debris from flying.

[0025] A workbench 18 is fixedly installed on the bottom inner wall of the work frame 1. Two second toothed plates 7 are slidably and horizontally arranged above the workbench 18. The two second toothed plates 7 slide towards each other or away from each other. The opposing sides of the two second toothed plates 7 are connected to clamping plates 10 through first elastic elements. The two second toothed plates 7 are in transmission cooperation with connecting plates 3.

[0026] Two first toothed plates 5 are fixedly installed at both ends of the connecting plate 3 in the vertical direction. Two first gears 6 are rotatably installed on the working frame 1. The first gears 6 mesh with the first toothed plates 5 one by one and mesh with the second toothed plates 7 one by one.

[0027] The first elastic element includes a first telescopic rod 9, which is fixedly mounted on a second toothed plate 7. One end of the first telescopic rod 9 is fixedly embedded in the second toothed plate 7, and the other end is fixedly connected to a clamping plate 10. A first spring 91 is sleeved on the outer surface of the first telescopic rod 9. The first spring 91 has the same telescopic direction as the first telescopic rod 9. One end of the first spring 91 is fixedly connected to the second toothed plate 7, and the other end is fixedly connected to the clamping plate 10.

[0028] The downward movement of the connecting plate 3 causes the first toothed plate 5 to move downward simultaneously, which in turn drives the second toothed plate 7 to slide via the first gear 6, causing the two second toothed plates 7 to slide towards each other in the direction of approaching the metal part. The second toothed plates 7 drive the clamping plates 10 to slide simultaneously via the first spring 91, so that the two clamping plates 10 clamp and limit the metal part in the horizontal direction. After the clamping plates 10 come into contact with the metal part, as the second toothed plates 7 continue to slide, the first spring 91 is gradually compressed, and the clamping effect gradually increases.

[0029] Two sleeves 13 are vertically slidably positioned on opposite sides of the two clamping plates 10. The two sleeves 13 on the same clamping plate 10 are connected to the same abutment plate 15 through the second elastic element, and the sleeves 13 are engaged with the second toothed plate 7.

[0030] A third toothed plate 8 is fixedly mounted on the top of the second toothed plate 7. A second gear 11, which meshes with the third toothed plate 8, is rotatably mounted on the top of the clamping plate 10. A lead screw 12 is coaxially fixedly mounted on the bottom of the second gear 11. The number of lead screws 12 and sleeves 13 are equal and correspond one-to-one. Each lead screw 12 is threadedly engaged with the corresponding sleeve 13.

[0031] The second elastic element includes a second telescopic rod 14, which is fixedly installed inside each sleeve 13. The top of the second telescopic rod 14 is fixedly connected to the sleeve 13, and the bottom of the second telescopic rod 14 is fixedly connected to the abutment plate 15. A second spring 141 is sleeved on the outer surface of the second telescopic rod 14. The second spring 141 has the same telescopic direction as the second telescopic rod 14. The top of the second spring 141 is fixedly connected to the sleeve 13, and the bottom of the second spring 141 is fixedly connected to the abutment plate 15.

[0032] When the clamping plate 10 contacts the metal part, as the second toothed plate 7 continues to slide, the clamping plate 10 comes to a standstill, the first telescopic rod 9 and the first spring 91 retract, and the third toothed plate 8 drives the second gear 11 to rotate. The second gear 11 drives the sleeve 13 to move downward through the lead screw 12, and the sleeve 13 drives the abutment plate 15 to move downward through the second spring 141, so that the abutment plate 15 abuts against the top of the metal part, thereby clamping and limiting the metal part in the vertical direction. After the abutment plate 15 contacts the metal part, as the abutment plate 15 continues to move downward, the second spring 141 and the second telescopic rod 14 gradually retract, and the clamping effect gradually increases.

[0033] The accompanying diagrams in this manual are structural schematics; their actual size may be adjusted based on actual use.

[0034] Working principle: When drilling is required, place the metal part on the worktable 18, start the first cylinder 2, and the telescopic shaft of the first cylinder 2 pushes the drill 4 to move closer to the metal part through the connecting plate 3.

[0035] As the connecting plate 3 moves downward, it causes the first toothed plate 5 to move downward simultaneously, which in turn drives the second toothed plate 7 to slide through the first gear 6, causing the two second toothed plates 7 to slide towards each other in the direction closer to the metal part. The second toothed plates 7 will drive the clamping plate 10 to slide simultaneously through the first spring 91, so that the two clamping plates 10 clamp and limit the metal part in the horizontal direction.

[0036] When the clamping plate 10 contacts the metal part, as the second toothed plate 7 continues to slide, the clamping plate 10 remains stationary. The first telescopic rod 9 and the first spring 91 gradually retract, and the clamping effect in the horizontal direction gradually increases. Meanwhile, the third toothed plate 8 drives the second gear 11 to rotate. The second gear 11 drives the sleeve 13 to move downward through the lead screw 12. The sleeve 13 drives the abutment plate 15 to move downward through the second spring 141, so that the abutment plate 15 abuts against the top of the metal part, thereby clamping and limiting the metal part in the vertical direction. After the abutment plate 15 contacts the metal part, as the abutment plate 15 continues to move downward, the second spring 141 and the second telescopic rod 14 gradually retract, and the clamping effect in the vertical direction gradually increases.

[0037] Then, the drill rig 4 passes through the protective cover 17 to drill holes in the surface of the metal parts.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
