Description

Technical Field

[0001] The present invention relates to the field of probe assembly, and more particularly to a probe crimping device. Background Art

[0002] Precision single-action probes are a type of micro-connector widely used in fields such as aviation, aerospace, navigation, military, medical, microelectronics, optoelectronics, etc. The structural features of the probe mainly include: a needle tube, a spring, a movable needle tip, a fixed needle tip, etc. The manufacturing process includes pre-installation: (placing the movable needle tip and spring inside the needle tube) riveting: inserting the fixed needle tip into the pre-installed needle tube and crimping the fixed needle tip and the needle tube together at the crimping points. Due to the small size of the product, the diameter of the precision probe is less than 0.4 mm. Traditional crimping equipment uses 4 punching needles for mechanical linkage to achieve crimping. The traditional equipment has the disadvantages that it is inconvenient to adjust the length deviation of the probe, and it is easy to have uneven crimping points during the production process, which affects the quality. Summary of the Invention

[0003] In order to improve the problem that multiple probes of conventional crimping equipment are synchronously linked, resulting in inconvenient adjustment of the length deviation of the probes and easy occurrence of uneven crimping points affecting the quality, the present invention provides a probe crimping device.

[0004] The probe crimping device provided by the present invention adopts the following technical solutions:

[0005] A probe crimping device includes a lifting component for lifting and fixing the needle. A connection base for fixing is installed at the bottom of the lifting component. A plurality of connection ports for docking with external control devices and power supply devices are arranged on the side surface of the connection base. A connection housing is arranged at the top of the lifting component. A communication port communicating with the lifting component is opened in the middle of the connection housing. A crimping component one for crimping the workpiece is arranged on the inner surface of the connection housing.

[0006] The crimping component one includes a mounting seat inserted and arranged on the inner wall of the connection housing. A plurality of rotating ports are opened on the surface of the mounting seat. A mounting port is penetrated through the middle of the mounting seat. A plurality of cams are rotatably arranged on the upper end surface of the connection housing. Servo motors are arranged at the positions of the plurality of cams inside the connection housing.

[0007] A telescopic rod is arranged at the top of the lifting component. A needle body for fixing the workpiece is arranged at the top of the telescopic rod. The needle body includes a needle tube arranged between the lifting component and the crimping component one. A telescopic spring is arranged inside the needle tube. A movable needle tip is movably arranged at the bottom of the spring inside the needle tube. A fixed needle tip inserted into the workpiece is fixedly arranged at the top of the spring inside the needle tube.

[0008] By adopting the above technical solution, the metal rod for processing is inserted into the first pressing point assembly and the second pressing point assembly from top to bottom, so as to form a plug-in fixation with the fixed needle head, avoiding shaking. Then, four servo motors independently control the rotation of the quarter cams. The rotation of the cams drives the stamping structures in the first pressing point assembly and the second pressing point assembly to collide with the surface of the metal rod respectively, thereby forming a stamping process, enabling the four stamping structures to be independently regulated and set the crimping pressure, avoiding the problems of uneven pressing points and inconvenient debugging.

[0009] Preferably, the second pressing point assembly is butt-jointed at the top of the first pressing point assembly, and a cover plate for sealing and fixing is arranged at the top of the second pressing point assembly.

[0010] By adopting the above technical solution, the second pressing point assembly is butt-jointed with the first pressing point assembly, and at the same time, the cover plate is covered with the connection housing from top to bottom, thereby fixing the second pressing point assembly and the first pressing point assembly inside the connection housing, improving stability.

[0011] Preferably, the second pressing point assembly includes a lower base inserted into the installation opening. A lower needle hole is opened at the bottom of the lower base communicating with the installation opening. An intermediate seat is sleeved around the outer surface of the lower base. An installation groove is opened in the middle of the intermediate seat, and the inner wall of the installation groove is in movable contact with the outer surface of the lower base.

[0012] By adopting the above technical solution, the lower base is inserted into the installation opening, so as to be integrally fixed with the installation seat. At the same time, the intermediate seat is sleeved on the outer surface of the lower base and then fixed synchronously with the installation seat, providing a fixed housing and a movable space for the installation of the subsequent crimping assembly.

[0013] Preferably, pressing holes are opened on the side surface of the intermediate seat at positions corresponding to a plurality of cams. The pressing holes communicate with the installation groove, and a rotating guide block is fixedly arranged around one end of the inner wall of the pressing hole.

[0014] By adopting the above technical solution, a plurality of pressing holes are centered and aligned with a plurality of cams one by one, so as to facilitate applying a thrust force to the inside of the pressing holes when the cams rotate. At the same time, the rotating guide block fixedly arranged on the inner wall of the pressing hole provides a meshing support for the rotation of the subsequent pressure-receiving rod.

[0015] Preferably, a crimping assembly is elastically arranged in each of the plurality of pressing holes. The crimping assembly includes a pressure-receiving rod movably inserted into the pressing hole. One end of the pressure-receiving rod extends from the pressing hole to the range of the lower needle hole. A boosting block is sleeved around the surface of the end of the pressure-receiving rod away from the lower needle hole. One end of the side surface of the boosting block is fixedly provided with a torsion spring, and the end of the torsion spring away from the boosting block is fixedly connected with the side surface of the lower base.

[0016] By adopting the above technical solution, the compression rod is movably arranged in the downward pressing hole. At the same time, the pressurizing block is wrapped and connected to one end of the outer surface of the compression rod. The pressurizing block drives the compression rod to move synchronously along the downward pressing hole under the action of a thrust, and applies pressure to the torsion spring to form compression. When the thrust on the pressurizing block is lost, the torsion spring stops being squeezed and rebounds, thereby pushing the compression rod out of the downward pressing hole in the opposite direction.

[0017] Preferably, a rotation groove is circumferentially formed on the outer surface of the pressurizing block, and the rotation groove is engaged with a rotation guide block.

[0018] By adopting the above technical solution, the rotation groove formed on the surface of the pressurizing block is engaged with the rotation guide block. When the pressurizing block extends into the downward pressing hole, the rotation guide block forms a mutual acting force on the pressurizing block through the rotation groove, so that the pressurizing block drives the whole compression rod to rotate.

[0019] Preferably, two grooves are inwardly formed at one end of the downward pressing hole far from the rotation guide block, and a ray sensor and a friction plate are telescopically arranged in the grooves respectively.

[0020] By adopting the above technical solution, the ray sensor detects the compression rod extending into the downward pressing hole. When the compression rod does not pass through the detection range of the ray sensor, the friction plate is controlled to extend upward, so that the compression rod extending in for the second time contacts the surface of the friction plate to generate friction, thereby polishing and maintaining the front end of the compression rod.

[0021] Preferably, a dismounting seat is inserted on the top of the lower base in the mounting groove, and the dismounting seat includes a fixing plate threadedly connected to the top of the lower base.

[0022] By adopting the above technical solution, the fixing plate is threadedly connected to the lower base, so as to maintain the overall stability of the fixing plate and the lower base. At the same time, the fixing plate can be detachably moved, so as to maintain and replace the mechanism inside the lower base.

[0023] Preferably, a slot is inwardly formed on the top of the fixing plate, and an upper needle hole is formed through the fixing plate in the middle of the slot, and the upper needle hole is aligned and communicated with the lower needle hole.

[0024] By adopting the above technical solution, the slot formed on the surface of the fixing plate forms a butt joint with the external workpiece conveying mechanism, so as to keep the workpiece placement aligned. At the same time, the opening of the upper needle hole reserves an installation space for the insertion of the workpiece, and the upper needle hole is aligned with the lower needle hole, so that the workpiece can be inserted into the lower needle hole through the upper needle hole.

[0025] Preferably, upper pressing holes are formed on the side surface of the fixing plate at the positions of a plurality of downward pressing holes, and the plurality of upper pressing holes are respectively aligned with the plurality of downward pressing holes one by one.

[0026] By adopting the above technical solution, multiple upper pressing holes are aligned with multiple lower pressing holes, thereby forming a channel for the lateral movement of the compression rod. While maintaining the movement of the compression rod, the movement of the compression rod is limited to prevent deviation.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0028] 1. The fixed needle is inserted and fixed with the metal rod, and the telescopic rod extends to push the movable needle, so that the movable needle squeezes the spring, and the syringe is pushed out to complete the feeding process after the metal rod is processed. At the same time, after the metal rod is fixed, four servo motors respectively drive four cams to conduct thrust on the crimping assembly to complete the stamping process of the metal rod. During the stamping process, the four crimping assemblies are independently controlled and the pressure is set separately, so as to distinguish the stamping process of metal rods with different materials and different stamping directions, ensure that the pressure points of the stamped metal rods are uniform, and at the same time facilitate personnel to adjust the stamping pressure of the crimping assembly;

[0029] 2. By means of the engagement of the rotating groove and the rotating guide block, part of the thrust conducted by the cam is converted into a rotational force applied to the surface of the booster block, so that the booster block drives the compression rod to move laterally and rotate. During this period, the auxiliary rotational force generated during the compression of the torsion spring is used to make the striker end of the compression rod contact and generate friction with the friction plate, so as to polish the surface of the striker. Finally, the thickness is increased by the rotation of the cam, so that the polished striker collides and stamps the metal rod, avoiding the problem of uneven pressure points caused by pits on the surface of the striker due to long-term collisions.

[0049] The following further describes the present invention in detail with reference to the attached drawings. Figures 1-9

[0050] An embodiment of the present invention discloses a probe crimping device.

[0051] Embodiment 1

[0052] Referring to Figure 1 、 Figure 3 、 Figure 5 A probe crimping device includes a lifting assembly 1. A connecting base 5 is fixed to the lower end surface of the lifting assembly 1 by screws. A plurality of side surfaces of the connecting base 5 are respectively fixedly connected with wiring ports, and the plurality of wiring ports are respectively docked with external devices such as a control device and a power supply device. An empty slot is opened inside the housing of the lifting assembly 1, and an electric push rod is loaded in the empty slot. The telescopic end of the electric push rod is fixedly provided with a telescopic rod 7. The telescopic rod 7 is located at the center of the housing of the lifting assembly 1, and the top of the telescopic rod 7 protrudes from the upper end surface of the housing of the lifting assembly 1 movably, and a concave groove is opened inward at the protruding top end;

[0053] At the top of the telescopic rod 7, there is a needle body 8. The needle body 8 includes a needle tube 81 fixedly arranged on the upper end surface of the telescopic rod 7. Inside the needle tube 81, a movable needle head 82 is movably arranged. The movable needle head 82 extends out from the bottom of the needle tube 81 and is clamped and fixed in the concave groove. Inside the needle tube 81, a spring 83 is fixedly connected at the top of the movable needle head 82. One end of the spring 83 away from the movable needle head 82 is fixedly connected with a fixed needle head 84. The end of the fixed needle head 84 protrudes from the top of the needle tube 81, and the surface of the fixed needle head 84 is set to be stepped. By applying pressure deformation to the outer surface of the needle tube 81 subsequently, it forms a fixation with the stepped part of the fixed needle head 84.

[0054] It should be noted that a trapezoidal groove is opened downward at the top of the fixed needle head 84. Under normal conditions, an external metal rod is inserted downward into the trapezoidal groove, so as to form a lateral clamping fixation with the fixed needle head 84. The metal rod is actually the workpiece to be processed, and the length of the tube body of the needle tube 81 is adjusted according to the size of the workpiece to be processed.

[0055] Refer to Figure 2 、 Figure 3 、 Figure 4 As shown in

[0056] At the top of the lifting assembly 1, four connecting columns are fixedly arranged around the telescopic rod 7, and a connecting housing 2 is inserted downward from the top of the four connecting columns. A communication port 10 is opened in the middle of the connecting housing 2. The end of the fixed needle head 84 protrudes synchronously from the communication port 10. Inside the connecting housing 2, there is a pressure point assembly one 3. The pressure point assembly one 3 includes a mounting seat 31 fixedly arranged on the inner surface of the communication port 10. A mounting opening 33 is penetrated through the center of the mounting seat 31. The mounting opening 33 is aligned with the center of the fixed needle head 84. Four cams 32 are rotatably connected around the upper end surface of the mounting seat 31. The cams 32 are integrally circular. At the same time, notches are successively opened inward layer by layer on the side surface of the cams 32. Inside the mounting seat 31, servo motors 34 are fixedly screwed at the positions of the four cams 32. The output shafts of the four servo motors 34 movably penetrate through the upper end surface of the mounting seat 31 and are fixedly connected to the central axes of the four cams 32 one by one.

[0056] It should be noted that the surfaces of the four cams 32 are set to be stepped recesses, and the number of steps is adjusted according to actual requirements. Rotating openings 9 are opened at the positions of the four cams 32 on the upper end surface of the mounting seat 31, so as to reserve a moving space for the rotation of the cams 32. A pressure point assembly two 4 is inserted and fixed on the upper end surface of the mounting seat 31. A cover plate 6 is covered on the upper end surface of the pressure point assembly two 4. The bottom of the side surface of the cover plate 6 is detachably connected to the upper end surface of the connecting housing 2, so as to form a seal inside the connecting housing 2.

[0057] The implementation principle of a probe crimping device according to an embodiment of the present invention is as follows: When using this device, the metal rod to be processed is inserted into the second crimping point assembly 4 through the cover plate 6, and then inserted into the center position of the installation port 33 from the second crimping point assembly 4. When the bottom of the metal rod is inserted and fixed to the fixed needle 84, the microcomputer controls the rotation of four servo motors 34 respectively. The rotation of the four servo motors 34 drives the rotation of four cams 32, and the operator rotates the four cams 32 at different angles according to data such as the material and density of the metal rod;

[0058] Under normal conditions, the concave surface of the cam 32 abuts against the pressure increasing block 461 and the pressure receiving rod 462. As the cam 32 rotates, the thickness of the abutting surface between the cam 32 and the pressure increasing block 461 and the pressure receiving rod 462 increases, thereby generating an extrusion force to push the pressure increasing block 461 and the pressure receiving rod 462. The pressure increasing block 461 and the pressure receiving rod 462 are pushed by the thrust force and are pressed into the hole formed by the lower pressing hole 45 and the upper pressing hole 434, so as to abut against the surface of the metal rod. As the cam 32 continues to rotate, it punches the surface of the metal rod, thereby generating the groove to be processed. The four cams 32 can be independently controlled to process the surface of the metal rod, which is convenient for controlling the different pressures applied to different directions of the metal rod, preventing problems such as uneven crimping points and inconvenient debugging.

[0059] Embodiment 2

[0060] Refer to Figure 5 、 Figure 6 、 Figure 7 In this embodiment, the difference from Embodiment 1 is that the second crimping point assembly 4 includes a lower base 41 inserted into the installation port 33. A lower needle hole 44 is formed through the bottom of the lower base 41, and the lower needle hole 44 is aligned with the center of the fixed needle 84. A threaded groove is formed inward on the upper end surface of the lower base 41, and the threaded groove communicates with the lower needle hole 44. At the same time, a rectangular protrusion is provided in the middle of the surface of the lower base 41, and an intermediate seat 42 is sleeved around the surface of the rectangular protrusion. An installation groove 421 is formed in the middle of the intermediate seat 42, and the installation groove 421 communicates with the threaded groove of the lower base 41. Four lower pressing holes 45 are formed through the inner wall surface of the installation groove 421 and penetrate the intermediate seat 42, and the inner walls of the four lower pressing holes 45 are tapered and contracted from the outside to the inside. Two grooves are formed downward at the part where the inner wall of the lower pressing hole 45 has the smallest contraction. A ray sensor 49 is fixedly installed in one groove close to the installation groove 421, and an electric push rod is fixedly installed in the other groove, and a friction plate 48 is fixedly installed at the telescopic end of the electric push rod;

[0061] A crimping component 46 is horizontally movably arranged in each of the four downward pressing holes 45. The crimping component 46 includes a pressure-receiving rod 462 inserted into the downward pressing hole 45. A boosting block 461 is fixedly arranged around the surface of one end of the pressure-receiving rod 462. One end of the pressure-receiving rod 462 away from the boosting block 461 is set as a firing pin. And normally, the end of the firing pin is located at the part with the smallest shrinkage of the inner wall of the downward pressing hole 45, and the end of the pressure-receiving rod 462 where the boosting block 461 is located protrudes from the outer surface of the middle seat 42 and abuts against the surface of the cam 32. A torsion spring 463 is fixedly arranged on the surface of one side of the boosting block 461 facing the firing pin. The other end of the torsion spring 463 forms a fixation with the part of the surface of the lower base 41 located in the downward pressing hole 45, so as to form an overall elastic connection. At the same time, an arc-shaped rotating guide block 47 is protrudingly arranged on the inner wall of the downward pressing hole 45 at the position of the boosting block 461, and rotating grooves 464 are arranged at the positions of the boosting block 461 where the rotating guide block 47 is located. The arc of the rotating groove 464 is adapted to and meshes with the arc of the rotating guide block 47.

[0062] It should be noted that, as Figure 8 , Figure 9 shown, the surface of the friction plate 48 is a conical inclined surface, and the inclined surface is made of a mixture of rubber powder and metal fibers. A disassembly seat 43 is inserted into the installation groove 421. The disassembly seat 43 includes a fixing plate 431 that can be movably disassembled in the installation groove 421. A convex mouth that fits into the threaded groove of the lower base 41 is arranged at the bottom of the fixing plate 431, and threads adapted to the threaded groove are arranged on the surface of the convex mouth. At the same time, a slot 432 is opened downward at the top of the fixing plate 431. A upper needle hole 433 is opened through the center of the bottom of the slot 432 and penetrates through the fixing plate 431. The upper needle hole 433 is aligned and communicated with the lower needle hole 44. Four upper pressing holes 434 are horizontally opened on the lower end surface of the fixing plate 431. The four upper pressing holes 434 and the four downward pressing holes 45 are spliced to form a circular hole channel, so as to facilitate the horizontal movement of the pressure-receiving rod 462. The middle parts of the four upper pressing holes 434 and the four downward pressing holes 45 are smooth surfaces, so as to maintain the insertion action of the pressure-receiving rod 462 and prevent the pressure-receiving rod 462 from rotating after contacting the metal rod.

[0063] Among them, the device also includes a cam 32, a servo motor 34, a ray inductor 49, an electric push rod, an externally arranged control device, and a power supply device, which are all prior arts, and their structural principles will not be elaborated here.

[0064] The implementation principle of Embodiment 2 is as follows: As the striker end of the compression rod 462 collides with the metal rod, friction is generated. The collision end of the metal rod is worn, shortening its overall length. At this time, since the length of the striker is shortened, when the cam 32 rotates and adjusts to the conventional thickness, the end of the striker cannot block the radiation end of the radiation sensor 49. First, the servo motor 34 reverses, so that the cam 32 adjusts its surface to the thinnest state. The torsion spring 463 loses pressure, and thus the pressure increasing block 461 and the compression rod 462 are ejected from the circular through hole formed by the lower pressing hole 45 and the lower pressing hole 45.

[0065] Meanwhile, the radiation sensor 49 sends a signal to control the operation of the electric push rod at the bottom of the friction plate 48. The telescopic end of the electric push rod extends, driving the friction plate 48 to protrude from the lower pressing hole 45, so that the surface of the friction plate 48 contacts the surface of the striker. As the servo motor 34 drives the cam 32 to rotate forward, the surface thickness of the cam 32 increases, applying a thrust to the pressure increasing block 461 and the compression rod 462. During the movement of the pressure increasing block 461 and the compression rod 462, the rotation groove 464 engages with the rotation guide block 47 and inserts, applying a rotational force to the whole pressure increasing block 461 and the compression rod 462. At the same time, the torsion spring 463 is under pressure, maintaining a reduced state and rotating slightly. Thus, the pressure increasing block 461 and the compression rod 462 are pressed into the circular through hole and rotate at the same time, making the striker end of the compression rod 462 contact the surface of the friction plate 48. The rotation of the compression rod 462 drives the striker to generate friction with the surface of the friction plate 48 for polishing.

[0066] When the polishing of the striker is completed, the rotation angle of the servo motor 34 increases, so that the thickness upper limit of the rotation of the cam 32 is adjusted to the next stepped thickness. As the abutting surface thickness of the cam 32 increases, the striker end of the compression rod 462 is inserted again to contact the surface of the metal rod for the stamping process. As the usage time increases, when the thickness of the cam 32 increases to the maximum and the length of the striker is still insufficient, the operator disassembles the cover plate 6, and then rotates the fixing plate 431, so that the fixing plate 431 is disassembled from the surface of the lower base 41. As the fixing plate 431 is disassembled, the upper pressing hole 434 is disengaged, and the striker end of the compression rod 462 and the torsion spring 463 are exposed to the outside, so as to carry out replacement and maintenance. Thus, it is convenient for the maintenance and replacement of the surface of the striker, avoiding uneven pressing points caused by different convex and concave shapes of the collision end of the striker.

[0067] The above are only optional embodiments of the present disclosure and are not used to limit the present disclosure. For those skilled in the art, various changes and modifications can be made to the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
