Description

Technical Field

[0001] The invention belongs to the technical field of ultrasonic C-scan water jet detection, and in particular relates to a special-shaped workpiece fixing bracket based on adaptive technology, which adopts an adjustable clamp to support and clamp the detection workpiece. Background Art

[0002] During the ultrasonic C-scan water jet inspection process, the probe maintains a constant distance from the workpiece surface, and ultrasonic inspection is achieved through coupling with the sprayed water column. Therefore, the workpiece to be inspected needs to be supported and fixed to keep it in a certain stable posture, and the angle and fixed position can be adjusted within a certain range to facilitate ultrasonic water jet inspection. Since most of the workpieces to be inspected are irregular shaped structures such as wings, the workpiece fixing bracket needs to be adaptively adjusted for different workpieces. The existing clamping tools have certain limitations in terms of adaptability and flexibility for special-shaped workpieces. Therefore, a set of workpiece brackets with high versatility, flexible movement, stable clamping and easy installation are designed for special-shaped workpieces. Summary of the invention

[0003] The purpose of the present invention is to provide a special-shaped workpiece fixing bracket based on adaptive technology to improve the detection efficiency of ultrasonic C-scan.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A special-shaped workpiece fixing bracket based on adaptive technology, four universal wheels are arranged at the bottom of the main frame, a main frame vertical long rod is arranged on the main frame, a lifting frame is arranged in the middle of the main frame vertical long rod, and an adjustable clamp is arranged on the upper part of the main frame vertical long rod. The lifting frame and the adjustable clamp can be moved and locked on the main frame vertical long rod, the adjustable clamp is provided with two clamp swing arms, quick-tightening clamps are fixed at the front end of the clamp swing arms, a lifting arm is arranged on the lifting frame, and a lifting frame V-groove is arranged at the front end of the lifting arm.

[0006] The adjustable clamp is connected to the vertical long rod of the main frame through the adjustable clamp extension rod.

[0007] The main frame is made of welded stainless steel square tubes.

[0008] The V-groove of the lifting frame and the contact part of the workpiece are made of polyoxymethylene resin material.

[0009] During the clamping process of the special-shaped workpiece, the two fixed brackets are arranged symmetrically, and the distance between the two fixed brackets is adjusted according to the overall length of the special-shaped workpiece.

[0010] When the special-shaped workpiece is large or a single adjustable clamp is difficult to clamp stably, multiple sets of adjustable clamps can be added to the vertical long rod of the main frame as needed.

[0011] First, manually lift the special-shaped workpiece to the lifting frame and place it on the V-groove of the lifting frame. Adjust the lifting arm according to the placement of the special-shaped workpiece and lock the lifting arm after the adjustment. Then, adjust the angle of the clamp swing arm on the adjustable clamp and the extension length of the adjustable clamp extension rod according to the contour of the side of the special-shaped workpiece so that the quick-tighten clamp is aligned with the thin wall marked on the side of the special-shaped workpiece. Manually tighten the quick-tighten clamp to stably clamp the side of the special-shaped workpiece. Finally, push the special-shaped workpiece fixing bracket and the special-shaped workpiece to the inspection position, lock the universal wheel, and complete the support and fixation work of the special-shaped workpiece before inspection.

[0012] The beneficial effects achieved by the present invention are:

[0013] The bottom of the bracket adopts a universal wheel with a lock to achieve flexible adjustment of the position of the fixed bracket and the workpiece. The lifting frame adopts a V-groove design. The bottom of the workpiece is automatically locked after it is placed on the lifting frame, and the installation is quick and convenient. The clamp arm can be adaptively adjusted according to the side curve of the workpiece, with high compatibility. The quick-tightening clamp does not require other tools to lock the workpiece. According to the clamping requirements of the workpiece, multiple sets of clamps can be quickly installed on the vertical long rod of the main frame to achieve stable clamping of the workpiece. Both the lifting frame and the clamp can be adjusted on the vertical long rod of the main frame to achieve quick adjustment of the fixed height of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Four universal wheels 5 are arranged at the bottom of the main frame 1, a main frame vertical long rod 6 is arranged on the main frame 1, a lifting frame 2 is arranged in the middle of the main frame vertical long rod 6, an adjustable clamp 3 is arranged on the upper part of the main frame vertical long rod 6, the lifting frame 2 and the adjustable clamp 3 can be moved and locked on the main frame vertical long rod 6, the adjustable clamp 3 is provided with two clamp swing arms 4, the front ends of the clamp swing arms 4 are fixed with quick-tightening clamps 9, a lifting arm 10 is arranged on the lifting frame 2, a lifting frame V-shaped groove 7 is arranged at the front end of the lifting arm 10, and the adjustable clamp 3 is connected to the main frame vertical long rod 6 through the adjustable clamp extension rod 8. The main frame 1 is made of stainless steel square pipe welding. The contact part of the lifting frame V-shaped groove 7 and the workpiece is made of polyoxymethylene resin material.

[0020] Two special-shaped workpiece brackets form a set of clamps to clamp and fix the two ends of the workpiece. The bracket is divided into the main frame, the lifting frame and the adjustable clamp. The main frame is made of stainless steel square tube welding, and the overall structure is firm. The surface finish of stainless steel is high, and the surface will not rust in a water splash environment. The four universal wheels at the bottom of the main frame can still flexibly adjust the position after the workpiece is clamped. After reaching the detection position, the bracket and the workpiece are locked as a whole through the universal wheel lock. The lifting frame is mainly used to lift the workpiece and support the workpiece. The V-shaped groove allows the workpiece to be placed on the bracket quickly and conveniently. At the same time, the parts in contact with the workpiece are made of polyoxymethylene resin to avoid damage to the surface of the workpiece. The adjustable clamp mainly clamps the thin-walled surfaces on the sides of the workpiece at both ends. After the lifting frame supports the workpiece, the workpiece is firmly clamped to prevent the workpiece from tipping over. The clamp is equipped with two swing arms, and the front end of the swing arm is fixed with a quick-tightening clamp. The adjustment of the jaw spacing is achieved by adjusting the swing arm angle to adapt to the clamping of different thicknesses and curvatures on the side of the workpiece. The quick-tightening clamp can be quickly clamped by hand, effectively improving the installation speed of the workpiece. At the same time, according to the clamping requirements of the workpiece, one or more sets of adjustable clamps can be installed for simultaneous clamping. The lifting frame and adjustable clamp can be moved and locked on the vertical long rod of the main frame. The height of the lifting frame and clamp can be adjusted according to the detection height requirements of the workpiece.

[0021] The special-shaped workpiece fixing bracket is mainly composed of a main frame 1, a lifting frame 2 and an adjustable clamp 3. The main frame 1 is mainly composed of a frame, a main frame vertical rod 6 and a universal wheel 5. The main structure of the lifting frame 2 is composed of a lifting arm 10 and a lifting frame V-shaped groove 7. The adjustable clamp 3 is mainly composed of a clamp swing arm 4, an adjustable clamp extension rod 8 and a quick-tightening clamp 9. During the workpiece clamping process, the two brackets are arranged symmetrically, and the distance between the two brackets is adjusted according to the overall length of the workpiece. First, the workpiece is manually lifted to the lifting frame 2 and placed on the lifting frame V-shaped groove 7 thereon. The lifting arm 10 is adjusted according to the placement posture of the workpiece, and the lifting arm 10 is locked after the adjustment is completed. Then, according to the contour of the side of the workpiece, the angle of the clamp swing arm 4 on the adjustable clamp 3 and the extension length of the adjustable clamp extension rod 8 are adjusted to align the quick-tightening clamp 9 with the thin wall of the side mark of the workpiece. The quick-tightening clamp 9 is manually tightened to ensure that the side of the workpiece is stably clamped. When the workpiece is large or a single adjustable clamp 3 is difficult to stably clamp, multiple sets of adjustable clamps 3 can be added to the vertical long rod 6 of the main frame according to the needs to ensure stable and firm clamping of the workpiece. Finally, push the special-shaped workpiece fixing bracket and the workpiece to the detection position, lock the universal wheel 5 of the main frame, and the support and fixing work before the detection of the special-shaped workpiece can be completed.
