Description

Technical Field

[0001] This utility model relates to the field of mechanical clamping hand technology, specifically to a mechanical clamping hand for rare earth metal detection. Background Technology

[0002] Due to the importance of rare earth metals, their quality testing is a crucial step in ensuring product quality and performance. In traditional rare earth metal testing, manual testing methods dominate. This method has several limitations: 1. Heavy workload: Rare earth metal testing involves multiple steps, requiring testing personnel to work long hours and at high intensity, easily leading to fatigue and errors. 2. High labor intensity: Testing personnel need to manually handle and place samples, resulting in high labor intensity and potential safety hazards. 3. Results affected by human factors: During manual testing, the experience and skill level of the operator have a significant impact on the test results, making it difficult to guarantee consistency and accuracy. 4. Low testing efficiency: Different rare earth metal compositions require different testing instruments, and switching between instruments requires manual operation, leading to low testing efficiency.

[0003] Given the increasing importance of rare earth metals and the growing demand for their testing, the application of mechanical clamps in automated testing has gained increasing attention due to the limitations of traditional manual testing methods. By improving testing efficiency, ensuring consistency, reducing labor intensity, and enhancing adaptability, mechanical clamps offer a more efficient, accurate, and reliable solution for rare earth metal testing. With continuous technological advancements and the expansion of application areas, the prospects for mechanical clamps in rare earth metal testing will be even broader. Therefore, we have developed a mechanical clamp for rare earth metal testing that can solve the problem of stably gripping rare earth metal blocks in the testing process. Utility Model Content

[0004] The purpose of this invention is to provide a mechanical clamping hand for rare earth metal detection, so as to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A mechanical clamping hand for rare earth metal detection includes a claw body 1, a movable claw 2, a trapezoidal lead screw 5, and a three-phase geared motor 12. The three-phase geared motor 12 is mounted on a reducer flange 7, the claw body 1 is mounted on the lower side of the reducer flange 7, the trapezoidal lead screw 5 is connected to the output shaft of the three-phase geared motor 12 through a coupling sleeve 10, the movable claw 2 is mounted on the trapezoidal lead screw 5 through a trapezoidal nut 6, and a spherical pressure head 4 is provided on the movable claw 2 through bolts 16.

[0007] The claw body 1 consists of a vertical mounting rod and a lower claw platform fixed horizontally to the bottom of the front side of the mounting rod. The top of the mounting rod is fixed to the bottom of the reducer flange 7. A "T" slide with a front opening is vertically opened on the mounting rod. A pad block 3 is provided on the top of the lower claw platform.

[0008] The moving claw 2 consists of a vertical connecting rod and a horizontally fixed upper claw platform on the top front side of the connecting rod. The connecting rod is slidably disposed in the "T" slide of the claw body 1. A stepped hole a is vertically opened on the connecting rod. The trapezoidal nut 6 is fixedly installed in the stepped hole a. The trapezoidal screw 5 is inserted into the stepped hole a and threadedly connected to the trapezoidal nut 6.

[0009] The spherical indenter 4 has a stepped hole b vertically opened in the middle. The spherical indenter 4 is composed of a rectangular block and a hemispherical body integrally formed on the top of the rectangular block. The rectangular block of the spherical indenter 4 corresponds vertically to the pad block of the lower claw platform.

[0010] The moving claw 2 has a stepped hole c vertically opened on the upper claw platform. The bolt 16 is an internal hexagonal head bolt. The bolt 16 passes through the stepped hole b of the spherical pressure head 4 and the stepped hole c of the upper claw platform from bottom to top and is then locked and fixed by a nut.

[0011] The stepped hole c consists of a cylindrical hole one, a conical hole and a cylindrical hole two from bottom to top. The diameter of the cylindrical hole one is larger than the diameter of the cylindrical hole two. The hemispherical body of the spherical indenter 4 is located inside the conical hole, and the upper part of the rectangular block of the spherical indenter 4 is located inside the cylindrical hole one.

[0012] Thrust ball bearings 14 are installed on the upper and lower sides of the base plate of the reducer flange 7 on the trapezoidal screw 5. A precision nut 13 is installed on the trapezoidal screw 5 between the upper thrust ball bearing 14 and the connecting sleeve 10. A flange sleeve 8 is provided on the trapezoidal screw 5 between the lower thrust ball bearing 14 and the base plate of the reducer flange 7. A boss is provided on the trapezoidal screw 5 below the lower thrust ball bearing 14. A bearing pad 9 is provided between the boss and the lower thrust ball bearing 14.

[0013] A ring sensor 15 is installed on the trapezoidal lead screw 5.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. This utility model enables the moving claw on the trapezoidal nut to move in the clamping direction by setting a three-phase geared motor, a trapezoidal lead screw and a trapezoidal nut, thereby realizing the clamping and loosening between the spherical pressure head and the pad.

[0016] 2. The spherical indenter of this utility model produces the following technical effects: 1) Uniformly distributed clamping force: Due to its unique spherical shape, the spherical indenter can achieve a uniform distribution of clamping force when clamping a metal block. This avoids the stress concentration problem that may be caused by traditional planar indenters, reduces the deformation and damage of the metal block during the clamping process, and thus improves the accuracy and reliability of the detection; 2) Adaptability to metal blocks of different shapes and sizes: Rare earth metal blocks may have different shapes and sizes. The spherical indenter has a certain radius of curvature, which can adapt to the surface of metal blocks of different shapes, ensuring the tightness and stability of the clamping. At the same time, by adjusting the magnitude of the clamping force, the spherical indenter can also adapt to metal blocks of different sizes, improving the versatility and flexibility of the mechanical clamping hand; 3) Reduced friction and wear: During the clamping process, the contact area between the spherical indenter and the metal block is relatively large, which helps to reduce the pressure per unit area, thereby reducing friction and wear. This not only extends the service life of the spherical indenter and the metal block, but also reduces noise and vibration during the testing process, improving the comfort of the working environment; 4) Improved testing efficiency: The design of the spherical indenter makes the clamping process faster and more stable. Through precise force control and position adjustment, the spherical indenter can quickly clamp the metal block into the appropriate position, preparing it for subsequent testing. This improves the efficiency of the entire testing process and shortens the testing cycle; 5) Protection of the metal block surface: Rare earth metal blocks are usually of high value, and their surface quality has a significant impact on subsequent processing and use. The spherical indenter can reduce scratches and indentations on the surface of the metal block during clamping, protecting the surface quality of the metal block. This helps ensure the accuracy of the test results and also facilitates the subsequent processing and use of the metal block.

[0017] 3. The annular pressure sensor installed on the flange sleeve of this utility model can detect the magnitude of the clamping force of the mechanical clamping hand, thereby ensuring that the mechanical clamping hand has sufficient clamping force on the metal block while avoiding excessive clamping force that could damage the clamping hand.

[0044] Example 1

[0045] like Figure 1-22 This embodiment provides a mechanical clamping hand for rare earth metal detection, including a jaw body 1, a movable jaw 2, a trapezoidal lead screw 5, and a three-phase geared motor 12. The three-phase geared motor 12 is bolted to a reducer flange 7, and the jaw body 1 is bolted to the lower side of the reducer flange 7. The trapezoidal lead screw 5 is connected to the output shaft of the three-phase geared motor 12 via a coupling sleeve 10. A keyway is provided at the top of the trapezoidal lead screw 5, and a key that matches the keyway is provided on the inner wall of the coupling sleeve 10. The movable jaw 2 is mounted on the trapezoidal lead screw 5 via a trapezoidal nut 6, and a spherical pressure head 4 is provided on the movable jaw 2 via bolts 16.

[0046] The claw body 1 consists of a vertical mounting rod and a lower claw platform horizontally fixed to the bottom front side of the mounting rod. The top of the mounting rod is fixed to the bottom of the reducer flange 7. A "T"-shaped slide with a front opening is vertically opened on the mounting rod. A pad 3 is bolted to the top of the lower claw platform. A through hole a with a diameter of 60mm is opened on the rear side of the mounting rod, and four through holes b with a diameter of 18mm are opened around the through hole a.

[0047] The movable claw 2 consists of a vertical connecting rod and a horizontally fixed upper claw platform at the top front of the connecting rod. Vertical protrusions are integrally formed on both sides of the connecting rod. The connecting rod is slidably disposed within a "T"-shaped slide rail of the claw body 1. A stepped hole a is vertically formed on the connecting rod. A trapezoidal nut 6 is bolted and fixed to the top of the stepped hole a. A trapezoidal lead screw 5 is inserted into the stepped hole a and threadedly connected to the trapezoidal nut 6. The rotating trapezoidal lead screw 5 drives the movable claw 2 to move up and down via the trapezoidal nut 6 on it.

[0048] The moving claw 2 has a stepped hole c vertically opened on the upper claw platform. The bolt 16 is an internal hexagonal head bolt. The bolt 16 passes through the stepped hole b of the spherical pressure head 4 and the stepped hole c of the upper claw platform from bottom to top and is then locked and fixed by a nut, thereby fixing the spherical pressure head 4 on the upper claw platform.

[0049] The spherical indenter 4 has a stepped hole b vertically formed in the middle. The spherical indenter 4 is composed of a rectangular block and a hemispherical body integrally formed on the top of the rectangular block. The rectangular block of the spherical indenter 4 corresponds vertically to the pad block of the lower claw platform. The stepped hole b is composed of a large-diameter cylindrical hole on the lower side and a small-diameter cylindrical hole on the upper side.

[0050] The diameter of the large-diameter cylindrical hole on the lower side of the stepped hole b is smaller than the diameter of the internal hexagonal head of the bolt 16, and the diameter of the small-diameter cylindrical hole on the upper side of the stepped hole b is smaller than the outer diameter of the internal hexagonal head of the bolt 16. The stepped hole c consists of a cylindrical hole one, a conical hole, and a cylindrical hole two from bottom to top. The diameter of cylindrical hole one is larger than the diameter of cylindrical hole two. The hemispherical body of the spherical indenter 4 is located inside the conical hole and is tangent to the inner wall of the conical hole. The upper part of the rectangular block of the spherical indenter 4 is located inside cylindrical hole one, and there are gaps between the rectangular block and the inner wall and shoulder of cylindrical hole one.

[0051] Thrust ball bearings 14 are installed on the upper and lower sides of the base plate of the reducer flange 7 on the trapezoidal lead screw 5. A precision nut 13 is threaded onto the trapezoidal lead screw 5 between the upper thrust ball bearing 14 and the connecting sleeve 10. A flange sleeve 8 is provided on the trapezoidal lead screw 5 between the lower thrust ball bearing 14 and the base plate of the reducer flange 7, and an annular sensor 15 is installed on the flange sleeve 8. An annular boss is provided on the trapezoidal lead screw 5 below the lower thrust ball bearing 14, and a bearing pad 9 is provided between the boss and the lower thrust ball bearing 14.

[0052] The working principle of this utility model is as follows: the three-phase geared motor 12 transmits power to the trapezoidal lead screw 5 through the reducer. Since the trapezoidal lead screw 5 and the trapezoidal nut 6 mesh with each other, the moving claw 2 set on the trapezoidal nut 6 can move in the clamping direction, thereby realizing the clamping and loosening between the spherical pressure head 4 and the pad on the claw body 1. At the same time, the annular pressure sensor 15 set on the flange sleeve 8 can detect the magnitude of the clamping force of the mechanical clamping hand, thereby ensuring that the mechanical clamping hand has sufficient clamping force on the metal block while avoiding excessive clamping force that could damage the clamping hand.
