Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a stable machining fixture. Background Technology

[0002] Thin-walled parts refer to structural parts with relatively small wall thickness. The processing of thin-walled parts often requires special methods to avoid deformation or damage during the processing operation. When processing thin-walled parts, a processing fixture is needed to hold the thin-walled parts first. The processing fixture for thin-walled parts is a special tool designed for processing thin-walled workpieces. It aims to ensure the stability of the workpiece during the processing, prevent deformation, and improve processing accuracy and efficiency.

[0003] Most existing machining fixtures use jaws to hold thin-walled parts, but this method can easily cause deformation of thin-walled parts, and slight deformation is difficult to detect with the naked eye. Therefore, those skilled in the art have provided a stable machining fixture to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stable machining fixture that makes thin-walled parts more stable and effectively prevents deformation of thin-walled parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable machining fixture, comprising six clamping mechanisms, six monitoring mechanisms, a disc, and six stabilizing grooves. An outer cylinder is fixedly installed on the outer side of the upper end face of the disc. A circular groove is formed in the middle of the upper end face of the disc. Three inner sliding grooves are evenly formed on the inner wall of the circular groove. Three outer sliding grooves are evenly formed on the outer end face of the disc. An inner lead screw is embedded in the inner wall of each of the three inner sliding grooves on the side away from the circular groove. An outer lead screw is embedded in the inner wall of each of the three outer sliding grooves on the side closer to the circular groove.

[0006] The six clamping mechanisms include six sliders, each with an arc plate fixedly mounted on its upper surface. The six monitoring mechanisms include six locking blocks, each with a non-contact optical sensor fixedly mounted on its upper surface.

[0007] Furthermore, an inner cylinder is fixedly provided at the middle position of the upper end face of the disk, and multiple anti-slip pads are fixedly provided on the lower end face of the disk.

[0008] Furthermore, the six stabilizing grooves are respectively located in the middle of the bottom surfaces of the three inner sliding grooves and the three outer sliding grooves, and the six sliders are respectively slidably disposed on the inner walls of the three inner sliding grooves and the three outer sliding grooves.

[0009] Furthermore, a stabilizing block is fixedly provided at the middle position of the lower end face of each of the six sliders, and the six stabilizing blocks are respectively slidably disposed on the inner wall of the six stabilizing grooves.

[0010] Furthermore, each of the six sliders has a threaded hole on its front end face, and the three inner screws and three outer screws are respectively threaded onto the inner wall of the six threaded holes.

[0011] Furthermore, each of the six clamping blocks has a threaded clamping bolt on its inner wall, and the opposite end faces of the six clamping bolts are movably disposed on the outer end face of the outer cylinder.

[0012] Furthermore, an annular groove is provided on the upper end face of the outer cylinder, and an annular block is fixedly provided on the top surface of each of the six locking blocks, and the six annular blocks are slidably disposed on the inner wall of the annular groove.

[0013] This utility model has the following beneficial effects:

[0014] 1. The present invention proposes a stable machining fixture, which places a thin-walled part above a disc, and rotates the outer lead screw and the inner lead screw to drive the clamping mechanism to slide on the inner wall of the outer slide groove and the inner slide groove. The clamping mechanism on the inner wall of the outer slide groove presses on the outer end of the thin-walled part, and the clamping mechanism on the inner wall of the inner slide groove presses on the inner end of the thin-walled part, making the thin-walled part more stable to be clamped. The inner and outer clamping effectively avoids the deformation of the thin-walled part.

[0015] 2. The present invention proposes a stable processing fixture. The clamping mechanism clamps the thin-walled part by means of an arc plate. The arc plate has a more dispersed compressive force, which can reduce the deformation of the thin-walled part. In addition, a monitoring mechanism is set above the outer cylinder. The surface of the thin-walled part can be monitored by a non-contact optical sensor inside the monitoring mechanism, which can promptly determine whether the thin-walled part is deformed.

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.

[0023] Reference Figure 1 , Figure 2 An embodiment of this utility model provides a stable machining fixture, including six clamping mechanisms 1, six monitoring mechanisms 3, a disc 10 and six stabilizing grooves 7. An outer cylinder 2 is fixedly installed on the outer side of the upper end face of the disc 10. A circular groove 8 is opened in the middle of the upper end face of the disc 10. Three inner sliding grooves 11 are evenly opened on the inner wall of the circular groove 8. Three outer sliding grooves 5 are evenly opened on the outer end face of the disc 10. An inner lead screw 6 is embedded in the inner wall of the three inner sliding grooves 11 on the side away from the circular groove 8. An outer lead screw 9 is embedded in the inner wall of the three outer sliding grooves 5 on the side closer to the circular groove 8.

[0024] An inner cylinder 12 is fixedly installed at the middle position of the upper end face of the disc 10. Multiple anti-slip pads 13 are fixedly installed at the lower end face of the disc 10. Six stabilizing grooves 7 are respectively opened at the middle position of the inner bottom surface of the three inner sliding grooves 11 and the three outer sliding grooves 5. Six sliders 102 are respectively slidably installed on the inner walls of the three inner sliding grooves 11 and the three outer sliding grooves 5. Six stabilizing blocks 104 are respectively slidably installed on the inner walls of the six stabilizing grooves 7. Three inner screws 6 and three outer screws 9 are respectively threaded onto the inner walls of the six threaded holes 103. The opposite end faces of the six extrusion bolts 304 are movably installed on the outer end face of the outer cylinder 2. An annular groove 4 is opened on the upper end face of the outer cylinder 2. The six annular blocks 302 are all slidably installed on the inner wall of the annular groove 4.

[0025] Specifically, the thin-walled part is placed above the disc 10. The outer lead screw 9 and the inner lead screw 6 are rotated to drive the clamping mechanism 1 to slide on the inner walls of the outer slide groove 5 and the inner slide groove 11. The clamping mechanism 1 on the inner wall of the outer slide groove 5 presses against the outer end of the thin-walled part, and the clamping mechanism 1 on the inner wall of the inner slide groove 11 presses against the inner end of the thin-walled part, so that the thin-walled part is stably clamped. An anti-slip pad 13 is provided below the disc 10 to make the disc 10 more stable. In addition, an outer cylinder 2 is provided above the disc 10, and a monitoring mechanism 3 is provided above the outer cylinder 2. The monitoring mechanism 3 monitors the surface of the thin-walled part to determine whether the thin-walled part is deformed, making the processing of the thin-walled part more convenient.

[0026] Reference Figure 3 , Figure 4 The six clamping mechanisms 1 include six sliders 102, and each of the six sliders 102 has an arc plate 101 fixedly installed on its upper end surface. The six monitoring mechanisms 3 include six locking blocks 303, each of the six locking blocks 303 has a non-contact optical sensor 301 fixedly installed on its upper end surface. Each of the six sliders 102 has a stabilizing block 104 fixedly installed at the middle position of its lower end surface. Each of the six sliders 102 has a threaded hole 103 opened on its front end surface. Each of the six locking blocks 303 has a compression bolt 304 threadedly fitted on its inner wall. Each of the six locking blocks 303 has a ring block 302 fixedly installed on its inner top surface.

[0027] Specifically, a stabilizing block 104 is provided below the slider 102 inside the clamping mechanism 1. The stabilizing block 104 slides inside the stabilizing groove 7 below the slide groove, allowing the slider 102 to slide stably inside the slide groove. Moreover, the arc plate 101 above the slider 102 is arc-shaped and fits against the end face of the thin-walled part. The arc-shaped arc plate 101 can greatly avoid deformation of the thin-walled part. The monitoring mechanism 3 mainly uses a non-contact optical sensor 301 to monitor the outer end face of the thin-walled part. This sensor can collect the emitted light to determine whether the thin-walled part is deformed. Moreover, rotating the clamping bolt 304 can loosen the fixing of the monitoring mechanism 3, so that the monitoring mechanism 3 can slide on the outer cylinder 2. Then, the clamping bolt 304 can be used to fix the monitoring mechanism 3 again, and it is convenient to disassemble the monitoring mechanism 3.

[0028] Working principle: The thin-walled part is placed above the disc 10. The outer lead screw 9 and the inner lead screw 6 are rotated to drive the clamping mechanism 1 to slide on the inner wall of the slide groove. The clamping mechanism 1 on the inner wall of the outer slide groove 5 presses on the outer end of the thin-walled part, and the clamping mechanism 1 on the inner wall of the inner slide groove 11 presses on the inner end of the thin-walled part, so that the thin-walled part is stably clamped. In addition, an outer cylinder 2 is set above the disc 10, and a monitoring mechanism 3 is set above the outer cylinder 2. The monitoring mechanism 3 monitors the surface of the thin-walled part to determine whether the thin-walled part is deformed.

[0029] Secondly, a stabilizing block 104 is provided below the slider 102 inside the clamping mechanism 1. The stabilizing block 104 slides inside the stabilizing groove 7 below the slide groove, allowing the slider 102 to slide stably inside the slide groove. Moreover, the arc plate 101 above the slider 102 is arc-shaped and fits against the end face of the thin-walled part. The monitoring mechanism 3 mainly uses a non-contact optical sensor 301 to monitor the outer end face of the thin-walled part. Furthermore, rotating the clamping bolt 304 can loosen the fixing of the monitoring mechanism 3, so that the monitoring mechanism 3 can slide on the outer cylinder 2. Then, the clamping bolt 304 can be used to fix the monitoring mechanism 3 again.

[0030] 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.
