Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical processing and non-destructive testing, and more specifically relates to a quick-disassembly chicken heart clamp. Background Art
[0002] In the nondestructive testing of shaft parts, measuring coaxiality and circular runout are key indicators. Traditional visual inspection equipment fixtures are typically mounted directly on the manipulator. However, when clamping shaft parts for inspection, these fixtures often suffer from unstable clamping, cumbersome adjustments, and difficult gripping. These issues negatively impact inspection efficiency and accuracy. Therefore, developing a heart-shaped fixture to simplify the manipulator's positioning and clamping processes is crucial for improving the overall effectiveness of nondestructive testing. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a quick-disassembly chicken heart clamp to solve the problem of inconvenience in clamping non-destructive testing of shaft parts.
[0004] The purpose and effect of the quick disassembly chicken heart clamp of the utility model are achieved by the following specific technical means:
[0005] A quick-detachable heart-shaped clamp comprises a heart-shaped clamp, wherein the heart-shaped clamp comprises a right plier leg and a left plier leg, wherein the right plier leg and the left plier leg are connected by a riveted shaft, a clamping head is installed on the top of the left plier leg, and connecting plates are installed on the surfaces of both sides of the left plier leg, one end of the connecting plate is connected by a first hinge pin, and the first hinge pin passes through the left plier leg, and a handle is installed on the end of the connecting plate away from the first hinge pin through a second hinge pin, and a cam is installed on one end of the handle, and when the handle is closed, the cam can resist the right plier leg, and clamping grooves are provided on the surfaces of the right plier leg and the left plier leg.
[0006] Furthermore, there are multiple clamping grooves, and the sizes of the clamping grooves are different.
[0007] Furthermore, a protective pad is provided in the clamping groove.
[0008] Furthermore, the clamping groove is in a 90° V-shape.
[0009] Furthermore, the material of the protection pad is polyurethane.
[0010] Furthermore, the thickness of the protection pad is less than 0.8 mm.
[0011] Furthermore, a stop handle is installed on the surface of the clamping head.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The utility model improves the detection efficiency during the detection process, simplifies the clamping process of the clamp by combining manual and automated methods, and realizes fast and accurate detection by using a manipulator and automated detection equipment.
[0014] This reduces damage to the workpiece. By locking the gripper in advance, it prevents the manipulator from scratching or bruising the workpiece due to inaccurate positioning or other unstable factors during the gripping process. During the pre-locking process of the pliers, the polyurethane also protects the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] As attached Figure 1 To the attached Figure 4 As shown:
[0026] The utility model provides a quick-disassembly heart-shaped clamp, comprising a heart-shaped clamp 4, wherein the heart-shaped clamp 4 comprises a right plier leg 10 and a left plier leg 11, wherein the right plier leg 10 and the left plier leg 11 are connected by a riveted shaft 12, a clamping head 13 is installed on the top of the left plier leg 11, and connecting pieces 14 are installed on the surfaces of both sides of the left plier leg 11, one end of the connecting piece 14 is connected by a first hinge pin 15, and the first hinge pin 15 passes through the left plier leg 11, and the end of the connecting piece 14 away from the first hinge pin 15 is installed with a handle 17 through a second hinge pin 16, and a cam 18 is installed at one end of the handle 17. When the handle 17 is closed, the cam 18 can abut against the right plier leg 10, and the surfaces of the right plier leg 10 and the left plier leg 11 are both provided with clamping grooves 19.
[0027] There are multiple clamping grooves 19 , and the sizes of the clamping grooves 19 are different.
[0028] Wherein, a protection pad 20 is provided in the clamping groove 19 .
[0029] The clamping groove 19 is in a 90° V-shape.
[0030] The material of the protection pad 20 is polyurethane.
[0031] The thickness of the protection pad 20 is less than 0.8 mm.
[0032] A stop handle 21 is installed on the surface of the clamping head 13 .
[0033] The specific usage and function of this embodiment are as follows:
[0034] To use the present invention, the operator first rotates the handle 17, causing the cam 18 on the handle 17 to rotate and separate from the clamp. The operator then pulls up on the handle 17 to separate the left and right legs 11 and 10, allowing the shaft-like workpiece to be placed into the clamping groove 19. The legs are then reunited, and the handle 17 is pulled down and rotated in the opposite direction. The right leg 10, under the action of the cam 18, clamps the workpiece. The V-shaped clamping groove 19 ensures the workpiece's axis is accurately positioned within the clamp, while the protective pad 20 protects the workpiece's surface from damage. Multiple clamping grooves 19 allow for the clamping of workpieces of varying diameters.
[0035] Then the heart-shaped fixture 4 containing the workpiece is placed in a specific tray, and the robot grasps the clamping head 13 of the heart-shaped fixture 4 according to a preset program and moves it to a designated position in the detection area.
[0036] In the detection area, two thimbles are clamped by the chuck, and the two thimbles are respectively aligned with the small holes at both ends of the workpiece for locking. Ethimble 1 3 is fixed and has the function of rotation. Ethimble 2 6 on the mobile base 2 can move along the guide rail 1. After thimble 1 3 and thimble 2 6 lock the workpiece, the stop handle 21 can be attached to the edge of the claw on the chuck, and then the rotating table 7 starts to drive thimble 2 6, thereby driving the workpiece to rotate. During the rotation of the workpiece, the detection sensor 5 shoots and processes the image of the workpiece to measure its outer diameter, taper and other external dimensions. The measurement results are transmitted to the control system in real time for analysis to achieve all-round detection. It should be noted that Figure 4 The testing mechanism in is the existing technology.
[0037] Based on the measurement results, the control system determines whether the workpiece is qualified and issues instructions to the sorting device. The sorting device sorts the workpieces according to the instructions and stores them in the corresponding areas. The workpiece data is uploaded to an Excel spreadsheet. Finally, the lifting handle 17 is manually rotated to separate the two clamp legs and remove the workpiece.
[0038] The heart-shaped clamp 4 improves inspection efficiency during testing. By combining manual and automated processes, it simplifies the clamping process. It also utilizes a robotic arm and automated testing equipment to achieve fast and accurate inspections. It also reduces damage to the workpiece: By pre-locking the clamp, it prevents scratches and bruises caused by inaccurate positioning or other unstable factors during the gripping process. The polyurethane also protects the workpiece during the pre-locking process.
[0039] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
