Description

Technical Field

[0001] This utility model relates to the technical field of resonant rod detection devices, and in particular to a detection device for precision machining tools of resonant rods. Background Technology

[0002] In modern high-end manufacturing industries, such as aerospace, communication equipment, and precision instruments, resonant rods are core components for signal processing and frequency control. Their machining accuracy directly determines the performance and reliability of the products. Due to the small size and complex structure of resonant rods, the requirements for testing parameters such as geometric dimensions, surface roughness, and material properties after machining are extremely stringent. In large-scale production, to ensure the consistency and stability of product quality, it is necessary to conduct rapid and efficient testing on a large number of resonant rod workpieces. Traditional testing methods are no longer sufficient to meet the ever-increasing production demands. Developing a precision machining tool testing device that can continuously test multiple workpieces has become a key link in ensuring product quality and improving production efficiency.

[0003] Most existing resonant rod testing devices use manual feeding and single-piece testing. Operators need to place the workpieces one by one on a fixed testing table and use measuring tools such as calipers and microscopes to perform manual measurements, or use automated testing instruments in fixed positions to complete the testing.

[0004] However, existing inspection devices have the problem of difficulty in continuously inspecting multiple workpieces. In actual production, traditional inspection devices cannot continuously inspect multiple workpieces, resulting in a lot of wasted time during the inspection process. In factories that mass-produce resonant rods, when using traditional single-piece inspection equipment, after each workpiece is inspected, it is necessary to manually replace the next workpiece or wait for the mechanical transmission device to transport the new workpiece to the inspection position. This results in long idle time for the equipment, which seriously affects the production progress. Therefore, a precision machining tool inspection device for resonant rods is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a detection device for precision machining tools of resonant rods, which aims to improve the problem that the existing technology cannot realize the continuous detection of multiple workpieces, resulting in a lot of wasted time during the detection process and affecting the production schedule.

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

[0007] A testing device for precision machining tools of resonant rods includes a testing platform, a support frame fixedly connected to the top of the testing platform, a hydraulic cylinder fixedly connected to the top of the support frame, a connecting plate fixedly connected to the output end of the hydraulic cylinder, a testing head fixedly connected to the bottom of the connecting plate, a fixed frame fixedly connected to the top of the testing platform, and a rotating component disposed inside the fixed frame.

[0008] The rotating assembly includes a rotating column, which is rotatably connected inside the fixed frame. A turntable is fixedly connected to the top of the rotating column, and a driven wheel is fixedly connected to the outer wall of the rotating column. A motor is fixedly connected inside the fixed frame, and a driving wheel is fixedly connected to the output end of the motor. The driving wheel and the driven wheel mesh with each other.

[0009] As a further description of the above technical solution:

[0010] A fixing seat is fixedly connected to the top of the fixing frame, and a fixing plate is fixedly connected to the top of the fixing seat.

[0011] As a further description of the above technical solution:

[0012] The fixed plate has a slider that is slidably connected inside, and a fixing component is provided on one side of the slider.

[0013] As a further description of the above technical solution:

[0014] The fixing component includes an inclined block and a locking block. One side of the inclined block is fixedly connected to one side of the slider, and one side of the locking block is fixedly connected to one side of the inclined block.

[0015] As a further description of the above technical solution:

[0016] A cylinder is fixedly connected to the bottom of the turntable, and a transmission column is fixedly connected to the output end of the cylinder. The transmission column passes through the turntable and the fixed base.

[0017] As a further description of the above technical solution:

[0018] A tapered column is fixedly connected to the top of the transmission column, and the tapered column is slidably connected inside the fixed plate, and the tapered column is in contact with the inclined block.

[0019] As a further description of the above technical solution:

[0020] A support column is fixedly connected inside the fixed plate, and the slider is slidably connected to the outer wall of the support column.

[0021] As a further description of the above technical solution:

[0022] A spring is fitted on the outer wall of the support column, and the two ends of the spring are fixedly connected to the inside of the fixing plate and the slider, respectively.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the starting motor drives the driving wheel to rotate, and the driving wheel meshes with the driven wheel to make the rotating column drive the turntable to rotate, rotating the workpieces sequentially to the bottom of the detection head. At the same time, the hydraulic cylinder pushes the detection head to perform detection. After the detection is completed, the turntable continues to rotate to drive the next workpiece to be detected, and loading and unloading are carried out simultaneously. This achieves the effect of continuous detection of multiple workpieces, solving the problem that it is impossible to continuously detect multiple workpieces, resulting in a lot of time wasted in the detection process and affecting the production progress, thereby improving the detection efficiency.

[0025] 2. In this utility model, the transmission column is pushed upward by the output end of the cylinder, which drives the conical column to slide. The conical column presses against the inclined block, causing the slider to slide against the spring force. This allows the locking block to extend and lock inside the workpiece, achieving a firm fixation. When the cylinder retracts, the spring resets and drives the locking block to retract and release the fixation. This effectively fixes the workpiece and solves the problem that the workpiece is prone to shaking and displacement during the inspection process, affecting the accuracy of the inspection data and the stability of the equipment, thereby improving the stability during inspection.

Detailed Implementation

[0033] 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.

[0034] Reference Figures 1-3 An embodiment of this utility model is provided: a detection device for precision machining tools of resonant rods, including a detection table 1, a support frame 2 fixedly connected to the top of the detection table 1, a hydraulic cylinder 3 fixedly connected to the top of the support frame 2, a connecting plate 4 fixedly connected to the output end of the hydraulic cylinder 3, a detection head 5 fixedly connected to the bottom of the connecting plate 4, a fixed frame 6 fixedly connected to the top of the detection table 1, and a rotating component provided inside the fixed frame 6.

[0035] The rotating assembly includes a rotating column 7, which is rotatably connected inside the fixed frame 6. A turntable 8 is fixedly connected to the top of the rotating column 7. During the rotation of the turntable 8, the workpiece placed above it rotates synchronously, allowing the workpiece to move smoothly to the bottom of the detection head 5. A driven wheel 9 is fixedly connected to the outer wall of the rotating column 7. A motor 10 is fixedly connected inside the fixed frame 6. A driving wheel 11 is fixedly connected to the output end of the motor 10. The driving wheel 11 and the driven wheel 9 mesh with each other. The driven wheel 9 and the driving wheel 11 at the output end of the motor 10 mesh through gear transmission to achieve smooth rotation. After the detection is completed, the turntable 8 continues to rotate, bringing the next workpiece to the bottom of the detection head 5, thus realizing continuous detection work.

[0036] Reference Figures 2-5A fixed base 12 is fixedly connected to the top of the fixed frame 6. A fixed plate 13 is fixedly connected to the top of the fixed base 12. A slider 16 is slidably connected inside the fixed plate 13. A fixed component is provided on one side of the slider 16. The fixed component includes an inclined block 17 and a locking block 18. One side of the inclined block 17 is fixedly connected to one side of the slider 16, and one side of the locking block 18 is fixedly connected to one side of the inclined block 17. A cylinder 14 is fixedly connected to the bottom of the turntable 8. A transmission column 21 is fixedly connected to the output end of the cylinder 14. The transmission column 21 passes through the turntable 8 and the fixed base 12. When the cylinder 14 is activated, its output end pushes the transmission column 21 upward, thereby driving the conical column 15 to slide within the fixed plate 13. A conical column 15 is fixedly connected to the top of the transmission column 21. The conical column 15 is designed with a gradually tapered structure, allowing it to move smoothly during movement. The tapered column 15 makes stable contact with the inclined block 17 and generates a large squeezing force. Through this squeezing action, the tapered column 15 drives the slider 16 to overcome the elastic force of the spring 20, so that the slider 16 slides smoothly along the support column 19. Finally, the locking block 18 extends and locks into the workpiece, ensuring that the workpiece remains in a stable fixed state during the inspection process. The tapered column 15 is slidably connected inside the fixed plate 13 and contacts the inclined block 17. The support column 19 is fixedly connected inside the fixed plate 13, and the slider 16 is slidably connected to the outer wall of the support column 19. The outer wall of the support column 19 is fitted with a spring 20. The two ends of the spring 20 are fixedly connected to the fixed plate 13 and the slider 16, respectively. When the cylinder 14 retracts, the elastic force of the spring 20 is restored, driving the slider 16 and the locking block 18 back to the initial position, thereby releasing the fixation of the workpiece.

[0037] Working principle: When using this resonant rod precision machining tool inspection device, the workpiece is first placed on multiple fixed components above the turntable 8 for fixation. Then, the motor 10 is started, and its output end drives the drive wheel 11 to rotate. The drive wheel 11 is forced to drive the driven wheel 9, which in turn drives the rotating column 7 to rotate within the fixed frame 6. The rotating column 7 then drives the turntable 8 at the top to rotate. The rotation of the turntable 8 can drive the workpiece placed on it to rotate synchronously. The turntable 8 drives the workpiece to rotate to the bottom of the inspection head 5. At this time, the hydraulic cylinder 3 is started, and its output end pushes the connecting plate 4 and the bottom inspection head 5 to move up and down, so that the inspection head 5 is closer to or away from the tool for inspection. After the inspection is completed, the rotation of the turntable 8 drives the next workpiece to move to the bottom of the inspection head 5. At the same time, the workpieces after the inspection are loaded and unloaded, thus achieving the effect of continuous inspection of multiple workpieces.

[0038] When fixing the workpiece, the workpiece is first placed on the outside of multiple inclined blocks 17 and clamping blocks 18. At this time, the cylinder 14 is activated, and its output end pushes the transmission column 21 to rise, causing the conical column 15 to slide inside the fixed plate 13. The conical column 15 contacts and presses against the inclined blocks 17, causing the slider 16 to overcome the elastic force of the spring 20 and slide along the support column 19, so that the clamping block 18 extends out and is clamped inside the workpiece, thus fixing the workpiece. When the cylinder 14 retracts, the spring 20 returns to its original position, causing the slider 16 and clamping block 18 to retract, releasing the fixation of the workpiece, thereby achieving the effect of effectively fixing the workpiece.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
