Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a positioning device for machining engine camshaft mounting holes. Background Technology

[0002] The positioning device for machining engine camshaft mounting holes is a specialized piece of equipment used in the machining field for positioning and clamping during engine camshaft machining. This device adjusts the position of the clamping components through a multi-dimensional drive structure, achieving stable clamping and precise positioning of the camshaft workpiece. This ensures that the workpiece does not shift during the machining of the mounting holes, guaranteeing machining accuracy, and is suitable for industrial machining scenarios of engine camshaft mounting holes.

[0003] Traditional positioning devices for machining engine camshaft mounting holes suffer from significant shortcomings in clamping stability and adjustment flexibility. Most devices have limited adjustment dimensions, failing to achieve multi-directional flexible adjustments in lateral, longitudinal, and positional correction directions. This makes it difficult to accurately adapt to the positioning requirements of different camshaft specifications, leading to workpiece clamping position deviations and affecting the machining accuracy of the mounting holes. Furthermore, the existing clamping structure design is unreasonable, lacking a stable force-bearing structure, resulting in insufficient clamping force and easy workpiece displacement during machining, further reducing machining quality. In addition, some devices lack stable guidance when the adjustment components move, easily experiencing displacement or jamming, failing to achieve smooth adjustment. This not only affects positioning efficiency but may also increase the risk of workpiece scrap due to adjustment errors, making it difficult to meet the positioning device requirements for high-precision machining of engine camshaft mounting holes. Therefore, we propose a positioning device for machining engine camshaft mounting holes. Utility Model Content

[0004] One of the technical problems this application aims to solve is that existing machining devices have limited adjustment dimensions, cannot achieve multi-directional flexible adjustment, are difficult to accurately adapt to the positioning requirements of camshafts of different specifications, and lack a stable force-bearing structure.

[0005] To address the aforementioned technical problems, this application provides a positioning device for machining engine camshaft mounting holes, comprising a support foot, a worktable fixedly connected to the upper end of the support foot, a first motor connected to one side of the outer wall of the worktable, a lead screw connected to one side of the first motor, a connecting rod movably connected to one side of the lead screw, a connecting plate fixedly connected to the middle of one side of the upper outer wall of the connecting rod, a second motor fixedly connected to one side of the upper end of the connecting plate, a hydraulic rod connected to the lower end of the second motor, a control device connected to the lower end of the hydraulic rod, a support plate fixedly connected to the lower end of the control device, a sliding groove formed on one side of the lower outer wall of the support plate, a third motor fixedly connected to one side of the lower outer wall of the support plate, an electric telescopic rod connected to one side of the third motor, a slider connected to the side of the electric telescopic rod away from the third motor, and a guide wheel fixedly connected to one side of the outer wall of the slider.

[0006] In some embodiments, a first slide rail is fixedly connected to both sides of the lower outer wall of the workbench, a second slide rail is fixedly connected to one side of the outer wall of the connecting plate, a processing device is fixedly connected to one side of the upper outer wall of the workbench, and two limiting devices are fixedly connected to one side of the upper outer wall of the support leg.

[0007] In some embodiments, the guide wheels connected on one side of the two limiting devices and the slider side are correspondingly connected.

[0008] In some embodiments, one side of the processing device is connected to the area formed between the limiting device and the guide wheel.

[0009] In some embodiments, both sides of the lower end of the connecting rod are movably connected to the lead screw and the first slide rail.

[0010] In some embodiments, the support plate and the connecting plate are movably connected by a hydraulic rod and a second slide rail.

[0011] In some embodiments, the slider is connected to a groove formed on the lower outer wall of the support plate.

[0012] In some embodiments, each side of the slider is provided with an electric telescopic rod, and the electric telescopic rod extends to the other side of the support plate and is fixedly connected to a third motor.

[0013] This utility model has at least the following beneficial effects: In use, this utility model demonstrates outstanding performance in workpiece clamping stability and multi-directional adjustment flexibility through its multi-dimensional drive clamping structure, composed of a first motor, lead screw, first slide rail, second motor, hydraulic rod, third motor, electric telescopic rod, guide wheel, support plate, and slider. During lateral adjustment, the first motor drives the lead screw to rotate, causing the connecting rod to smoothly shift laterally along the first slide rail, thus adjusting the lateral position of the guide wheel. During longitudinal adjustment, the second motor, via the hydraulic rod, drives the support plate to move longitudinally along the second slide rail, simultaneously changing the height of the guide wheel, while the second slide rail ensures that the support plate moves without deviation. For position correction and limiting, the third motor drives the electric telescopic rod to extend and retract, causing the slider to slide along the groove, precisely adjusting the position of the guide wheel to align with the limiting device, achieving stable workpiece clamping. Simultaneously, the two corresponding hydraulic rods, when connected to the guide wheel and the two limiting devices, form a closed and stable triangular structure, further enhancing clamping force, effectively preventing workpiece deviation during processing, and ensuring clamping stability. In use, the coordination between the processing device and the clamping mechanism plays a crucial role in ensuring the precision and convenience of the machining operation. The processing device is fixed to the upper end of the support leg, and its lower end can precisely align with the workpiece between the guide wheel and the limiting device. Thanks to the stable fixation and multi-directional precise adjustment of the clamping structure, the processing device can complete the machining operation stably and efficiently, reducing quality defects caused by workpiece misalignment. In addition, the coordinated control of various motors and drive components allows the guide wheel to achieve multi-directional offset, adapting to the clamping requirements of workpieces of different sizes and shapes, greatly improving the applicability and practicality of the device.

Detailed Implementation

[0016] 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.

[0017] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a positioning device for machining engine camshaft mounting holes, including a support foot 1, a worktable 2 fixedly connected to the upper end of the support foot 1, a first motor 3 connected to one side of the outer wall of the worktable 2, a lead screw 4 connected to one side of the first motor 3, a connecting rod 6 movably connected to one side of the outer wall of the lead screw 4, a connecting plate 7 fixedly connected to the middle of one side of the upper end of the connecting rod 6, a second motor 8 fixedly connected to one side of the upper end of the connecting plate 7, a hydraulic rod 9 connected to the lower end of the second motor 8, a control device 10 connected to the lower end of the hydraulic rod 9, and a control device 10 fixedly connected to the lower end of the control device 10. A support plate 11 is attached. A groove 12 is provided on one side of the lower outer wall of the support plate 11. A third motor 13 is fixedly connected to one side of the lower outer wall of the support plate 11. An electric telescopic rod 14 is connected to one side of the third motor 13. A slider 15 is connected to the side of the electric telescopic rod 14 away from the third motor 13. The slider 15 is correspondingly connected to the groove 12 provided on the lower outer wall of the support plate 11. An electric telescopic rod 14 is provided on both sides of the slider 15. The electric telescopic rod 14 extends to the other side of the support plate 11 and is fixedly connected to the third motor 13. A guide wheel 16 is fixedly connected to one side of the outer wall of the slider 15.

[0018] In this embodiment, a support foot 1 is designed, and a workbench 2 is fixedly connected to the upper end of the support foot 1. A first motor 3 is fixedly connected to one outer wall of the workbench 2, and a lead screw 4 is connected to one side of the first motor 3. A first slide rail 5 is provided on both outer walls of the lower end of the workbench 2. The first slide rail 5 is located at the upper end of the lead screw 4. A connecting rod 6 is movably connected to one side of the outer wall of the lead screw 4 and the first slide rail 5. A connecting plate 7 is fixedly connected to the middle of the outer wall of the upper end of the connecting rod 6. A second motor 8 is fixedly connected to the upper outer wall of the connecting plate 7, and a hydraulic rod 9 is provided at the lower end of the second motor 8. The hydraulic rod 9 extends to one side of the lower end of the connecting plate 7 and is fixedly connected to the support plate 11 provided at the lower end of the control device 10. Therefore, when the second motor 8 is started, the second motor 8 will drive the support plate 11 to move longitudinally through the hydraulic rod 9, and then drive the guide wheel 16 provided at the lower end of the support plate 11 to move longitudinally. When the first motor 3 is started, the first motor 3 will drive the connecting rod 6 through the lead screw 4. Lateral offset occurs, at which point the connecting rod 6 is limited by the first slide rail 5, allowing for smooth sliding. A second slide rail 17 is provided on one side of the connecting plate 7, and the second slide rail 17 is movably connected to the support plate 11. Therefore, when the support plate 11 moves longitudinally, it can slide smoothly through the second slide rail 17 without offset. A third motor 13 is fixedly connected to the outer wall of the lower end of the support plate 11. An electric telescopic rod 14 is connected to one side of the third motor 13. The electric telescopic rod 14 extends to one side of the inner wall of the support plate 11 and is fixedly connected to a slider 15. The slider 15 is slidably connected to the lower end of the support plate 11 through the slide groove 12. A guide wheel 16 is connected to one side of the slider 15. Therefore, when the third motor 13 is started, it drives the electric telescopic rod 14 to extend and retract, thereby driving the slider 15 and the guide wheel 16 to perform limiting and position correction. This allows the guide wheel 16 to be connected to the limiting device 19, providing a stable clamping effect for the processed parts.

[0019] Example 2: Please refer to Figure 1-3 A first slide rail 5 is fixedly connected to both sides of the lower outer wall of the worktable 2. The lower sides of the connecting rod 6 are movably connected to the lead screw 4 and the first slide rail 5. A second slide rail 17 is fixedly connected to one side of the outer wall of the connecting plate 7. The support plate 11 is movably connected to the connecting plate 7 through the hydraulic rod 9 and the second slide rail 17. A processing device 18 is fixedly connected to one side of the upper outer wall of the worktable 2. Two limiting devices 19 are fixedly connected to one side of the upper outer wall of the support foot 1. One side of the two limiting devices 19 is correspondingly connected to the guide wheel 16 connected to one side of the slider 15. One side of the processing device 18 is correspondingly connected to the area formed between the limiting device 19 and the guide wheel 16.

[0020] In this embodiment, the interaction between the first motor 3 and the second motor 8 enables the guide wheel 16 to shift in multiple directions, thereby achieving stable clamping of the item to be processed and preventing it from shifting during processing. A processing device 18 is fixedly connected to the outer wall of the upper end of the support leg 1. The lower end of the processing device 18 can be correspondingly connected to the item being processed between the guide wheel 16 and the limiting device 19. Therefore, the processing device 18 can perform processing operations on the item. The two hydraulic rods 9 provided on the upper outer wall of the worktable 2 are correspondingly connected. When the guide wheel 16 is connected to the two limiting devices 19, a closed and stable triangle is formed. This method can further clamp the object and prevent it from shifting during processing, which could lead to substandard quality.
