Description

Technical Field

[0001] This invention relates to the field of terminal block manufacturing technology, specifically to a pull-out testing and inspection mechanism for terminal block manufacturing. Background Technology

[0002] As a core component of electrical connections, the connection strength between the terminal block and the crimped part of the wire directly determines the reliability of the electrical system. During the factory inspection of terminal blocks, a pull-out test mechanism is required to perform a pull-out strength test on the crimped terminal blocks to verify whether the crimped connection between the terminal block and the wire meets the mechanical performance requirements. A pull-out test mechanism typically includes a testing machine frame, an upper fixed clamping seat, a lower fixed clamping seat, and a force sensor. During the test, both ends of the terminal block are clamped and fixed in the upper and lower fixed clamping seats respectively. The testing machine drives the clamping seats to move relative to each other, applying an axial tensile force to the terminal block. The force sensor collects the pull-out failure load, completing the terminal block pull-out performance test.

[0003] Current pull-out testing mechanisms used in terminal block production inevitably suffer from placement deviations during manual sample loading. When the sample is clamped and has different axes, additional bending moments are introduced into the sample in addition to the axial tensile force during tensile loading. These additional bending moments are superimposed on the terminal crimping position, changing the actual stress state of the terminal. This causes distortion in the peak pull-out load collected by the tensile sensor, resulting in large data dispersion in repeated tests of the same batch of samples, reducing the accuracy and repeatability of the test results, and lowering testing efficiency.

[0004] To address the above issues, a pull-out testing mechanism for terminal block production is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a pull-out testing mechanism for terminal block production. By using this device, the problem of distortion in the peak pull-out load collected by the tensile sensor due to unavoidable placement deviations during manual sample loading, as mentioned in the background, is solved.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A pull-out testing mechanism for terminal block production includes a base and a lifting component fixed to the surface of the base. An adjusting component is installed on one side of the lifting component, and a tensile sensor that can collect tensile force values ​​in real time during the pull-out process is fixedly installed on the other side of the adjusting component. A ball seat is fixedly installed at one end of the tensile sensor, and a universal ball head is provided inside one end of the ball seat. Clamping components for clamping and fixing the terminal block are fixedly installed at one end of the universal ball head and on the surface of the base, respectively. The ball seat and the universal ball head cooperate to form a universal follow-up structure. The universal ball head can perform small-angle adaptive swing to automatically compensate for the small angular deviation caused by sample loading and the sample axis deviation caused by the asymmetry of the terminal shape.

[0007] Furthermore, the clamping component includes a horizontal plate and a bidirectional screw rotatably connected inside the horizontal plate. The horizontal plate is fixedly connected to the base and the universal ball joint respectively. A knob is fixedly installed at one end of the bidirectional screw. A clamping plate is threadedly connected to the surface of the bidirectional screw, and the clamping plate is slidably connected to the horizontal plate.

[0008] Furthermore, a guide groove is provided inside the cross plate, and the clamping plate is slidably connected to the guide groove.

[0009] Furthermore, the adjusting component includes a fixed plate and a disc slidably connected inside the fixed plate. The fixed plate is fixedly connected to the lifting component. A connecting column is fixedly installed inside the disc. A first electric push rod and a second electric push rod are respectively installed inside the fixed plate. Push seats are fixedly installed at the output ends of the first electric push rod and the second electric push rod, and the push seats are rotatably connected to the disc.

[0010] Furthermore, two sets of sliding grooves are provided through the surface of the disc, and the push seat is tumbled into the sliding grooves.

[0011] Furthermore, the push base includes a connecting rod and rollers installed on both sides of the connecting rod. The connecting rod is fixedly connected to the output ends of the first electric push rod and the second electric push rod, respectively. The connecting rod is slidably connected to the disc, and the rollers are tumbledly connected to the slide groove.

[0012] Furthermore, an angle sensor for detecting the tilt angle of the universal ball joint is fixedly installed on one side of the universal ball joint.

[0013] Furthermore, a connecting plate is fixedly installed on the surface of the connecting column, and L-shaped rods are fixedly installed on both sides of the connecting plate.

[0014] Furthermore, a locking element for locking the universal ball joint is fixedly installed between the L-shaped rods; The locking component includes an annular plate and a fixed disc fixed inside the annular plate. The annular plate is fixedly connected to an L-shaped rod. A rotating disc is rotatably connected to the surface of the fixed disc. Several clamping plates are rotatably connected to one side of the rotating disc, and the clamping plates are in contact with universal ball joints. Several connecting plates are tilted and rotated on the surface of the rotating disc, and one end of the connecting plate is rotatably connected to the clamping plate. A toothed ring is fixedly installed on the outside of the rotating disc, and the toothed ring is rotatably connected to the annular plate. A motor is fixedly installed inside the annular plate, and a gear is fixedly installed at the output end of the motor, and the gear meshes with the toothed ring.

[0015] Furthermore, the lifting component includes a support plate and an electric slide rail fixed to one side of the support plate. The support plate is fixedly connected to the base, and the fixed plate is fixedly connected to the electric slide rail.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. A universal follow-up structure is formed by a ball seat and a universal ball head. During loading, the universal ball head can swing adaptively at a small angle to compensate for the sample axis deviation caused by sample placement deviation, ensure that the tensile force is applied along the sample axis, reduce the bending moment superimposed on the terminal, and restore the true axial pull-out force state of the terminal.

[0017] 2. After locking the ball head, the XY axis horizontal adjustment component is used to complete the large coaxial deviation correction, so that the tensile force is applied along the axis of the terminal sample, eliminating the additional bending moment and significantly improving the accuracy of test data and the repeatability of the same batch of samples.

[0018] 3. The tilt sensor collects the tilt angle of the universal ball joint in real time. When the tilt angle exceeds the threshold, the controller automatically triggers the locking and shaft centering process, replacing the subjective judgment of human eyes. It can give early warning of excessive coaxial offset, avoid the risk of test failure caused by the ball joint swing exceeding the limit, and improve the intelligence level of the equipment.

[0019] 4. The arrangement of dual electric push rods, together with the disc, slide, and roller push seat, constitutes a two-dimensional horizontal adjustment mechanism. The rolling action of the rollers reduces transmission resistance, and the orthogonal movements do not interfere with each other, which can smoothly adjust the XY axis position of the clamping component and correct the sample axis offset.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1 and Figure 3 As shown, the pull-out test mechanism for terminal block production includes a base 1 and a lifting component 2 fixed on the surface of the base 1. The lifting component 2 serves as the power actuator for the pull-out action, which can smoothly drive the upper component to move, providing a stable tensile driving force for the terminal block pull-out test, realizing controllable tensile loading, and ensuring a smooth pull-out test process. The lifting component 2 includes a support plate 21 and an electric slide rail 22 fixed to one side of the support plate 21. The support plate 21 is fixedly installed on the base 1, providing a rigid installation support reference for the electric slide rail 22. The support plate 21 is fixedly connected to the base 1, and the fixed plate 31 is fixedly connected to the electric slide rail 22. The electric slide rail 22 serves as a vertical drive component for the pulling action, driving the fixed plate 31 to perform precise vertical lifting and lowering movements. The electric slide rail 22 has the characteristics of controllable speed, continuous displacement, and smooth operation. It can provide a constant tensile rate according to standard requirements, meet the loading specifications of the terminal pull-out strength test, and ensure that the tensile curve collected by the tensile sensor 4 is true and effective.

[0024] To address the technical problem of distortion in the peak pull-out load collected by the tensile sensor 4 due to unavoidable placement deviations during manual sample loading, the following preferred technical solution is provided: like Figure 1 and Figure 2 As shown, an adjusting component 3 is installed on one side of the lifting component 2. A tension sensor 4, capable of acquiring the tension value during the pulling process in real time, is fixedly installed on one side of the adjusting component 3. A ball seat 5 is fixedly installed at one end of the tension sensor 4. A universal ball head 6 is provided inside one end of the ball seat 5. The ball seat 5 and the universal ball head 6 cooperate to form a universal follow-up structure, which serves as the core component for angle adaptive compensation. It can transmit axial tension while allowing the universal ball head 6 to swing at a small angle. This structure can isolate the lateral component force caused by the sample tilt, avoid the lateral load being directly transmitted to the tension sensor 4, and reduce the impact of lateral force on the tension sensor. To prevent damage to the device 4, protect the tension sensor 4, and extend the service life of the tension sensor 4, clamping parts 7 for clamping and fixing the terminals are fixedly installed on one end of the universal ball head 6 and the surface of the base 1, respectively. The two sets of clamping parts 7 form an upper and lower opposing clamping position, respectively clamping the two ends of the terminals to achieve reliable clamping and positioning of the sample. One set of clamping parts 7 floats synchronously with the universal ball head 6, while the other set of clamping parts 7 is fixed to the base 1. This ensures that the terminals are firmly clamped and can also cooperate with the universal follow-up structure to achieve adaptive angle adjustment, preventing clamping lock-up from causing the sample axis to be forcibly fixed and generating additional bending moment. The ball seat 5 and the universal ball head 6 work together to form a universal follow-up structure. The universal ball head 6 can swing at a small angle to automatically compensate for the small angle deviation caused by sample loading and the sample axis deviation caused by the asymmetry of the terminal shape. During the loading process, the universal ball head 6 follows the sample axis to swing at a small angle to automatically compensate for the coaxial deviation caused by the deviation of manual sample loading and placement. This makes the tensile force as close as possible to the axis of the terminal sample, eliminates additional bending moment, avoids test data distortion caused by bending moment, abnormal bending and breakage of the terminal clamping mouth, improves test efficiency, and ensures better repeatability of test data for the same batch of samples. The two ends of the terminal to be tested are clamped and fixed on two sets of clamping members 7. One set of clamping members 7 is installed on the end of the universal ball head 6, and the other set of clamping members 7 is fixed on the surface of the base 1. This completes the clamping and positioning of the terminal sample. After the test is started, the lifting member 2 moves upward along the base 1. The lifting member 2 simultaneously drives the adjusting member 3, the tension sensor 4, the ball seat 5, the universal ball head 6, and the clamping member 7 installed at the end of the universal ball head 6 to move upward as a whole. A tension force is applied to the terminal clamped between the two sets of clamping members 7. The tension force is transmitted to the tension sensor 4 through the clamping member 7. The tension sensor 4 collects the tension value of the entire pulling process in real time, thereby obtaining the pull-out strength data of the crimped part of the terminal. During the sample clamping process, factors such as the irregular shape of the terminals, human placement errors, and slight deformation caused by clamping and squeezing can easily lead to coaxial deviation at the clamping centers at both ends of the terminals. The ball seat 5 and the universal ball head 6 work together to form a universal follow-up structure. During the tensile loading process, the universal ball head 6 can undergo small-angle adaptive swinging to automatically compensate for the slight angular deviation caused by sample loading and the sample axis deviation caused by the asymmetry of the terminal shape. This ensures that the load applied to the terminals is transmitted along the sample's own axis as much as possible, avoiding the sample being subjected to additional bending moments. Therefore, the ball seat 5 and the universal ball head 6 form a universal follow-up structure. During the loading process, the universal ball head 6 can swing adaptively at a small angle to compensate for the deviation of the sample axis caused by the sample placement deviation, ensure that the tensile force is applied along the sample axis, reduce the bending moment superimposed on the terminal, and restore the true axial pull-out force state of the terminal.

[0025] like Figure 7 As shown, the clamping component 7 includes a horizontal plate 71 and a bidirectional screw 72 rotatably connected inside the horizontal plate 71. The horizontal plate 71 is fixedly connected to the base 1 and the universal ball joint 6 respectively. A knob 73 is fixedly installed at one end of the bidirectional screw 72. A clamping plate 74 is threadedly connected to the surface of the bidirectional screw 72. The clamping plate 74 is slidably connected to the horizontal plate 71. When the operator rotates the knob 73, the knob 73 drives the bidirectional screw 72 to rotate inside the horizontal plate 71. Since the two ends of the bidirectional screw 72 are provided with threads of opposite directions, when the bidirectional screw 72 rotates, the two sets of clamping plates 74 rely on the sliding fit between them and the horizontal plate 71 to make synchronous translational movements in opposite directions or in opposite directions along the horizontal plate 71. Two sets of clamping plates 74 approach each other and clamp the terminal placed between the two sets of clamping plates 74 to complete the sample fixation. Rotating the knob 73 in the opposite direction causes the bidirectional screw 72 to drive the two sets of clamping plates 74 away from each other, releasing the terminal and completing the sample unloading. During the pull-out loading stage, the horizontal plate 71 moves synchronously with the base 1 or the universal ball head 6. The clamping plates 74 maintain a clamped state to stably hold the terminal. The universal ball head 6 performs small-angle adaptive self-alignment. The bidirectional screw 72 keeps the clamping force of the clamping plates 74 stable, ensuring that the terminal will not slip or loosen during the pull-out test. The horizontal plate 71 has a guide groove 711 inside, and the clamping plate 74 is slidably connected to the guide groove 711. The guide groove 711 constrains the clamping plate 74. During the movement of the clamping plate 74, it can only move along the preset direction of the guide groove 711, so as to avoid the clamping plate 74 tilting or deviating when clamping the terminal. This ensures that the two sets of clamping plates 74 always move in parallel and opposite directions under the drive of the bidirectional screw 72, and the clamping surface always remains flat. This makes the clamping pressure of the clamping plate 74 on the terminal evenly distributed, avoids local deformation and skew of the terminal caused by single-point extrusion, and reduces the initial coaxial deviation generated after the sample is clamped.

[0026] To address the technical issue that excessive swing amplitude of the universal ball joint 6 can lead to inaccurate tension measurements, the following preferred technical solution is provided: like Figures 4-6 As shown, the adjusting component 3 includes a fixed plate 31 and a disc 32 slidably connected inside the fixed plate 31. The fixed plate 31 is fixedly connected to the lifting component 2. A connecting column 33 is fixedly installed inside the disc 32. A first electric push rod 34 and a second electric push rod 36 are respectively installed inside the fixed plate 31. Push seats 35 are fixedly installed at the output ends of the first electric push rod 34 and the second electric push rod 36, and the push seats 35 are tumblingly connected to the disc 32. In the initial state, the wiring terminals can be pre-pulled and calibrated first. The first electric push rod 34 and the second electric push rod 36 are arranged in an XY orthogonal direction. The output ends of the two electric push rods are connected to the push seats 35, and the push seats 35 maintain rolling contact with the disc 32. When the tilt sensor 8 detects that the tilt angle of the universal ball joint 6 exceeds a preset threshold, the controller drives the first electric push rod 34 or the second electric push rod 36 to extend or retract. The first electric push rod 34 or the second electric push rod 36 pushes the disk 32 to translate along the X or Y direction inside the fixed plate 31 through the push seat 35. The push seat 35 and the disk 32 are connected by a rolling connection to reduce the frictional resistance during the pushing process and reduce the driving load. When the disk 32 translates, it drives the tension sensor 4, ball seat 5, universal ball joint 6 and the corresponding clamping part 7 to move synchronously in the horizontal plane through the connecting column 33, realizing the horizontal position adjustment in both X and Y directions and completing the correction of the axis at both ends of the terminal sample. After the axis correction is completed, the equipment enters the pre-tension stage, and the universal ball joint 6 continues to undertake the small angle adaptive compensation, and then the pull-out test is officially carried out. Two sets of sliding grooves 321 are provided through the surface of the disc 32. The push seat 35 is rolledly connected to the sliding grooves 321. By opening the dedicated sliding grooves 321 on the surface of the disc 32, the rolling motion of the push seat 35 is precisely limited and guided, so that the movement trajectory of the push seat 35 strictly follows the extension direction of the sliding grooves 321, avoiding the problems of lateral displacement, slippage and derailment of the push seat 35 during the process of pushing the disc 32. The push base 35 includes a connecting rod 351 and rollers 352 mounted on both sides of the connecting rod 351. The connecting rod 351 is fixedly connected to the output ends of the first electric push rod 34 and the second electric push rod 36, respectively. The connecting rod 351 is slidably connected to the disc 32, and the rollers 352 are rollingly connected to the slide groove 321. When the first electric push rod 34 or the second electric push rod 36 extends or retracts, the first electric push rod 34 or the second electric push rod 36 drives the connecting rod 351 to move along the push rod axis, and the rollers 352 on both sides of the connecting rod 351 roll along the inner wall of the slide groove 321. While 52 rolls within the slide groove 321, it transmits thrust through the side wall of the slide groove 321, driving the disc 32 to move horizontally within the fixed plate 31. During unidirectional adjustment, the roller 352 in the other orthogonal direction can roll freely within the corresponding slide groove 321. The connecting rod 351 slides relative to the disc 32 to compensate for the slippage, preventing the adjustment actions in the X or Y directions from interfering with each other. After the disc 32 moves horizontally, it drives the connecting column 33, tension sensor 4, ball seat 5, universal ball head 6, and clamping member 7 to move horizontally synchronously, completing the axis correction in the XY direction.

[0027] like Figure 2 and Figure 4 As shown, an inclination sensor 8 for detecting the tilt angle of the universal ball joint 6 is fixedly installed on one side. A connecting plate 10 is fixedly installed on the surface of the connecting column 33. L-shaped rods 20 are fixedly installed on both sides of the connecting plate 10. The inclination sensor 8 monitors the tilt angle of the universal ball joint 6 in real time and can transmit the collected swing angle signal to the controller. The controller is existing technology and is not shown in the figure. A threshold for the allowed swing angle is preset. When the swing amplitude of the universal ball joint 6 is detected to be too large and exceeds the preset threshold, a warning signal can be output in time to remind the operator that there is a large coaxial offset of the current sample.

[0028] like Figure 5 and Figure 8As shown, a locking element 30 for locking the universal ball joint 6 is fixedly installed between the L-shaped rods 20. The locking element 30 includes an annular plate 301 and a fixed disk 302 fixed inside the annular plate 301. The annular plate 301 is fixedly connected to the L-shaped rods 20. A rotating disk 303 is rotatably connected to the surface of the fixed disk 302. Several clamping plates 304 are rotatably connected to one side of the rotating disk 303, and the clamping plates 304 are in contact with the universal ball joint 6. The multiple clamping plates 304 form an iris-type clamping structure, which simultaneously adheres to the spherical surface of the universal ball joint 6 from all sides when retracted, resulting in uniform circumferential force. After locking, it can stably fix the posture of the universal ball joint 6 and forcibly keep the ball joint vertical. When released, all clamping plates 304 expand outward synchronously, completely detaching from the universal ball head 6, without interfering with the subsequent swing compensation of the universal ball head 6. The multi-plate clamping can disperse contact stress and avoid local damage to the ball head caused by single-point compression. The rotating disk 303 has several connecting plates 305 on its tilted rotating surface, and one end of the connecting plate 305 is rotatably connected to the clamping plate 304. The rotating disk 303, as a power conversion component, converts its own circumferential rotation into the radial opening and closing motion of the clamping plate 304 synchronously through multiple sets of connecting plates 305. The rotating disk 303 drives all connecting plates 305 in one integrated manner, ensuring that all clamping plates 304 move synchronously and achieve uniform circumferential clamping. A gear ring 306 is fixedly installed on the outer side of the rotating disk 303, and the gear ring 306 is rotatably connected to the annular plate 301. A motor 307 is fixedly installed inside the annular plate 301. A gear 308 is fixedly installed at the output end of the motor 307, and the gear 308 is meshed with the gear ring 306. The tilt sensor 8 is electrically connected to the motor 307 through the controller. In the initial state, the multiple clamping plates 304 are separated from the universal ball head 6. The universal ball head 6 remains in a free floating state and can perform small-angle adaptive swing during the pulling loading process, playing a passive self-aligning compensation role. During the calibration phase, when the tilt sensor 8 detects that the swing angle of the universal ball head 6 exceeds the preset threshold, the lifting component 2 descends. The controller receives the signal from the tilt sensor 8 and controls the motor 307 to start. The motor 307 drives the gear 308 to rotate. The gear 308 drives the gear ring 306 and the rotating disk 303 fixed to the gear ring 306 to rotate synchronously through meshing transmission. When the rotating disk 303 rotates, it causes the inclined connecting plate 305 to swing. The connecting plate 305 further causes multiple clamping plates 304 to converge radially towards the center. Multiple sets of clamping plates 304 converge inward synchronously, forming a clamping action similar to an iris mechanism, which hugs the universal ball head 6 from the circumference and locks the universal ball head 6 in the initial vertical posture, restricting the universal ball head 6 from continuing to swing. After the universal ball joint 6 is locked, the controller drives the first electric push rod 34 or the second electric push rod 36 to move, pushing the disc 32 to move horizontally in the X-axis or Y-axis direction, which drives the tension sensor 4, ball seat 5, locking part 30 and universal ball joint 6 to move horizontally as a whole, completing the axis correction of the clamping position at both ends of the terminal block; Therefore, the locking component 30 adopts an iris-type multi-piece clamping structure. When the tilt sensor 8 detects that the swing angle of the universal ball head 6 is too large, it can automatically lock the universal ball head 6 in a vertical posture. After locking, the XY axis horizontal adjustment component 3 is activated to perform axis center correction. During the correction process, the angle of the universal ball head 6 remains fixed and will not swing randomly, avoiding loss of control of the ball head posture during the adjustment process, greatly improving the axis center correction accuracy, and realizing a two-level compensation combination of active correction for large offset and passive compensation for small deviation.
