Description

Technical Field

[0001] This invention relates to the field of machine tool wire harness terminal crimping testing technology, specifically to a machine tool wire harness terminal crimping flatness testing and correction device. Background Technology

[0002] Machine tool wire harness terminal crimping is the core process of machine tool wire harness processing. It refers to the process of applying pressure to the contact area between the wires and matching terminals of the machine tool wire harness to form them in a cold state, so as to achieve an inseparable and reliable electrical and mechanical connection, which directly determines the operational stability of the machine tool electrical system.

[0003] The machine tool wire harness terminal crimping flatness inspection and correction equipment is a specialized precision integrated quality inspection and correction device designed for machine tool wire harness processing scenarios. It is used to inspect the flatness of terminal crimping and simultaneously complete error correction to ensure that the crimping quality of machine tool wire harnesses meets industrial standards.

[0004] The equipment consists of a terminal cutting and grinding unit, a cross-sectional image acquisition system, high-precision measurement and analysis software, and a calibration execution module. Some models are equipped with a precision automatic cutting / grinding table driven by a Swiss motor, and feature a SONY industrial high-definition video system and a full-white adjustable LED cold light source, with a measurement accuracy of 1~2µm.

[0005] In conventional machine tool wire harness terminal crimping flatness testing and correction equipment, the structure of the cross-sectional image acquisition device is relatively fixed, which makes it impossible to flexibly adjust the acquisition angle according to the specifications of the terminal and the crimping position. This requires the staff to repeatedly disassemble and adjust the position of the acquisition device, which not only slows down the testing efficiency, but also easily introduces positional errors, affecting the accuracy of the final test results. Summary of the Invention

[0006] The purpose of this invention is to provide a machine tool wire harness terminal crimping flatness detection and correction device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a machine tool wire harness terminal crimping flatness detection and correction device, comprising a base component and a cross-section acquisition component. The base component has symmetrically slidably mounted movable seats at both ends of its top. The top of one movable seat on the top of the base component is detachably and fixedly mounted with the cross-section acquisition component, and the top of the movable seat on the other end of the base component is detachably and fixedly mounted with a fixing component. The cross-section acquisition component includes a stabilizing support column, a second guide rail, a stabilizing platform, a fastening bolt, and a high-definition microscopic imager body. The second guide rail is vertically fixed to the side wall of the stabilizing support column near the fixing component, and the stabilizing platform is slidably connected to the surface of the second guide rail. A fastening bolt is horizontally screwed through the upper side wall of the stabilizing platform, and the high-definition microscopic imager body is fixedly mounted at the bottom of the stabilizing platform, with the imaging end of the high-definition microscopic imager body facing the fixing component.

[0008] Furthermore, the base component includes a base, a first guide rail, and fixing holes. The first guide rail is fixedly installed in the middle of the top of the base along the horizontal length direction using a sunken structure, and fixing holes are provided at the four opposite corners of the base.

[0009] Furthermore, the base adopts a rectangular steel structure design, and the entire surface is treated with blackening and rust prevention to ensure that there will be no rust or deformation during long-term use of the equipment. The fixing holes are used in conjunction with bolts to fix the entire base component to the mounting structure surface.

[0010] Furthermore, the movable seat includes a slider, a support base, and a positioning bolt. The top end of the slider is integrally provided with a support base, and the top end of the slider away from the support base is vertically threaded with a positioning bolt for locking and fixing the position.

[0011] Furthermore, the bottom of the slider is provided with a guide groove that matches the surface of the first guide rail, and the slider is slidably connected to the first guide rail through the guide groove. Moreover, the screwing of the positioning bolt can lock the entire movable seat in the corresponding position of the first guide rail, thereby realizing the adjustment of the distance between the two movable seats.

[0012] Furthermore, the bottom of the stabilizing support is fixed to the top surface of the support base of one of the movable seats at the four diagonal points of the support column by bolts, and the end of the fastening bolt abuts against the surface of the second guide rail to lock the position of the stabilizing platform.

[0013] Furthermore, the fixing component includes a support frame, an auxiliary frame, an adjusting rod, an upper contact displacement sensor, a lower contact displacement sensor, and a limiting sleeve. The support frame is generally arranged in an L-shape, and an auxiliary frame is fixed to the top of the side of the support frame closest to the cross-section acquisition component. An adjusting rod is vertically threaded onto the end of the auxiliary frame away from the support frame, and an upper contact displacement sensor is installed at the bottom of the adjusting rod. At the same time, a lower contact displacement sensor is horizontally fixed to the top surface of the cross arm of the support frame, and a limiting sleeve is fixed to the side of the lower contact displacement sensor horizontally fixed at the lower end of the longitudinal arm of the support frame.

[0014] Furthermore, the bottom four diagonal points of the support frame are fixed to the top surface of the support base of another set of movable seats by bolts. The upper contact displacement sensor and the lower contact displacement sensor are vertically aligned. The limiting sleeve is used to insert and place the wire harness terminal to be tested, so that the crimped end face of the terminal to be tested is located between the upper contact displacement sensor and the lower contact displacement sensor. The two displacement sensors simultaneously detect the height data of different positions of the crimped surface of the terminal, transmit it to the external processing equipment to generate flatness parameters, and combine it with the crimped surface image acquired by the main body of the high-definition microscopic imager.

[0015] This invention provides a machine tool wire harness terminal crimping flatness detection and correction device, which has the following beneficial effects: 1. This invention utilizes a cross-sectional acquisition component and a set of movable seats. On one hand, a first guide rail guides a slider to drive a stabilizing support column for horizontal position adjustment. On the other hand, a second guide rail guides a stabilizing stage to drive the main body of the high-definition microscopic imager for vertical position adjustment. Compared with traditional fixed structure settings, the acquisition position can be flexibly adjusted quickly without repeated disassembly and assembly, avoiding positioning errors introduced by disassembly and assembly. At the same time, it effectively improves the efficiency of detection and adjustment, and adapts to the detection needs of terminals with different specifications and different crimping positions.

[0016] 2. In this invention, by using a fixed component and another set of movable seats in conjunction, after inserting the wire harness terminal to be tested into the limiting sleeve, rotating the adjusting rod can drive the upper contact displacement sensor to move downward. In conjunction with the lower contact displacement sensor, the height data of different positions of the terminal crimping surface is acquired synchronously. Combined with the end face image acquired by the main body of the high-definition microscopic imager, dual detection combining contact data detection and non-contact image acquisition is achieved, effectively improving the accuracy of flatness detection results.

[0017] 3. This invention, by using a detachable fixed connection between the base component, the movable seat, the cross-section acquisition component, and the fixed component, not only facilitates the assembly and transportation of the entire equipment, but also allows for the individual disassembly and replacement of a single component when it is worn or malfunctions, without the need to replace the entire equipment. This effectively reduces the subsequent maintenance costs of the equipment and extends its overall service life. Attached Figure Description

Detailed Implementation

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0021] like Figures 1 to 5 As shown, a machine tool wire harness terminal crimping flatness detection and correction device includes a base component 1 and a cross-section acquisition component 3. Movable seats 2 are symmetrically slidably mounted on both ends of the top of the base component 1. The cross-section acquisition component 3 is detachably and fixedly mounted on the top of one end of the movable seat 2 on the top of the base component 1, and a fixing component 4 is detachably and fixedly mounted on the top of the other end of the movable seat 2 on the top of the base component 1. The cross-section acquisition component 3 includes a stabilizing support 301, a second guide rail 302, a stabilizing platform 303, a fastening bolt 304, and a high-definition microscopic imager body 305. The second guide rail 302 is vertically fixed to the side wall of the stabilizing support 301 near the fixing component 4, and the stabilizing platform 303 is slidably connected to the surface of the second guide rail 302. The fastening bolt 304 is horizontally screwed through the upper side wall of the stabilizing platform 303, and the high-definition microscopic imager body 305 is fixedly mounted on the bottom of the stabilizing platform 303. The imaging end of the main body 305 is positioned facing the fixed component 4. The bottom of the stabilizing support column 301 is fixed to the top surface of the support base 202 of one of the movable seats 2 by bolts at four opposite corners. The end of the fastening bolt 304 abuts against the surface of the second guide rail 302 to lock the position of the stabilizing stage 303. In use, the slider 201 slides on the surface of the first guide rail 102, which drives the stabilizing support column 301 to adjust its position in the horizontal direction, thereby driving the main body 305 of the high-definition microscope imager to adjust its horizontal position synchronously. After reaching the target position, tightening the positioning bolt 203 completes the horizontal position locking. Then, the fastening bolt 304 can be loosened to drive the stabilizing stage 303 to slide vertically along the second guide rail 302 to adjust the vertical imaging height of the main body 305 of the high-definition microscope imager. After reaching the target position, tightening the fastening bolt 304 again locks the vertical position, which can quickly and flexibly adjust the imaging position to adapt to the acquisition needs under different working conditions.

[0022] like Figures 1 to 5As shown, the base component 1 includes a base 101, a first guide rail 102, and fixing holes 103. The first guide rail 102 is fixedly installed in the middle of the top of the base 101 along the horizontal length direction using a recessed structure. Fixing holes 103 are provided at the four opposite corners of the base 101. The base 101 adopts a rectangular steel structure design, and the entire surface is treated with black anti-rust treatment to ensure that there will be no rust or deformation during long-term use of the equipment. The fixing holes 103 are used in conjunction with bolts to fix the entire base component 1 to the mounting structure surface. The movable seat 2 includes a slider 201, a support seat 202, and a positioning bolt 203. The support seat 202 is integrally provided at one end of the top of the slider 201, and the end of the top of the slider 201 away from the support seat 202 is vertically threaded. A positioning bolt 203 is provided for locking and fixing the position. The bottom of the slider 201 has a guide groove that matches the surface of the first guide rail 102. The slider 201 is slidably connected to the first guide rail 102 through the guide groove. Tightening the positioning bolt 203 can lock the movable seat 2 in the corresponding position of the first guide rail 102, realizing the adjustment of the distance between the two movable seats 2. The fixing component 4 includes a support frame 401, an auxiliary frame 402, an adjusting rod 403, an upper contact displacement sensor 404, a lower contact displacement sensor 405, and a limiting sleeve 406. The support frame 401 is generally arranged in an L-shape. The auxiliary frame 402 is fixed to the top of the side of the support frame 401 closest to the cross-section acquisition component 3. The end of the auxiliary frame 402 away from the support frame 401 is vertical. An adjusting rod 403 is threadedly installed, and an upper contact displacement sensor 404 is installed at the bottom of the adjusting rod 403. Simultaneously, a lower contact displacement sensor 405 is horizontally fixed to the top surface of the cross arm of the support frame 401. A limit sleeve 406 is fixed to one side of the lower contact displacement sensor 405 at the lower end of the longitudinal arm of the support frame 401. The bottom of the support frame 401 is bolted to the top surface of the support base 202 of another set of movable seats 2 at four opposite corners. The upper contact displacement sensor 404 and the lower contact displacement sensor 405 are vertically aligned. The limit sleeve 406 is used to insert and place the wire harness terminal to be tested, so that the crimped end face of the terminal to be tested is located between the upper contact displacement sensor 404 and the lower contact displacement sensor 405, and the two displacement sensors... The sensors synchronously detect the height data at different positions on the terminal crimping surface and transmit it to an external processing device to generate flatness parameters. This data is then combined with the crimping surface image acquired by the high-definition microscope imager body 305. During operation, the first guide rail 102 on the surface of the base 101 guides the sliding of two movable seats 2. The distance between the two movable seats 2 is adjusted according to the terminal specifications. After locking the position, the terminal to be tested is inserted into the limiting sleeve 406, placing the terminal crimping end face between the upper contact displacement sensor 404 and the lower contact displacement sensor 405. Then, rotating the adjusting rod 403 moves the upper contact displacement sensor 404 downwards to contact the top of the terminal crimping surface, and the lower contact displacement sensor 405 contacts the bottom of the terminal crimping surface. The two displacement sensors synchronously acquire height data at different positions.The flatness parameters are generated by transmitting data to an external analysis device. Combined with the high-definition image of the crimped surface acquired by the high-definition microscope body 305, accurate detection of the terminal crimped flatness can be achieved. If the flatness is found to be substandard, an external calibration module can be used to correct the terminal crimped surface.

[0023] In summary, as Figures 1 to 5 As shown, this machine tool wire harness terminal crimping flatness detection and correction device, in use, firstly, fixes the base component 1 to the mounting structure surface through the fixing hole 103 and external bolts. Then, according to the specifications of the wire harness terminal to be tested, loosen the positioning bolts 203 on the two moving seats 2, slide the two moving seats 2 along the first guide rail 102 to adjust the distance, and tighten the positioning bolts 203 to complete the position locking. Next, loosen the fastening bolts 304 on the cross-section acquisition component 3, slide the stabilizing platform 303 vertically along the second guide rail 302 to adjust the shooting height of the high-definition microscopic imager body 305, and tighten the fastening bolts 304 to complete the position locking. Then, insert the wire harness terminal to be tested into the limiting sleeve 406 of the fixing component 4, so that the terminal is crimped flatness. The detection crimped end face is positioned between the upper contact displacement sensor 404 and the lower contact displacement sensor 405. Rotating the adjusting rod 403 causes the upper contact displacement sensor 404 to move downward, so that the two displacement sensors respectively contact the corresponding positions of the crimped surface. Then, the equipment is started, and the two displacement sensors simultaneously detect the height data of different positions of the terminal crimped surface and transmit the data to the external processing equipment to generate flatness parameters. At the same time, the high-definition microscopic imager body 305 acquires high-definition images of the terminal crimped surface. By combining contact data detection with non-contact image acquisition, the flatness of the terminal crimped surface is accurately detected. If the detection result shows that the flatness does not meet the standard, the terminal crimped surface can be corrected in conjunction with the external correction actuator.
