Description

Technical Field

[0001] This invention relates to the field of connector housing processing equipment, and more particularly to a drilling device for polygonal connector housings. Background Technology

[0002] The connector housing protects the internal structure of the connector and is typically made of metal, such as aluminum alloy. The housing blank is usually formed by stamping during the manufacturing process. However, to accommodate the internal structure of the connector, holes are often drilled in the connector housing for cable routing, etc.

[0003] Existing drilling setups typically include a drill bit and a support platform. The connector housing is fixed to the support platform using a clamp, and the drill bit moves back and forth relative to the support platform to achieve drilling. However, there is usually a certain positional error between the clamp and the drill bit, requiring multiple adjustments to the clamp's position. This results in low adjustment efficiency and low drilling position accuracy.

[0004] Therefore, existing drilling equipment for connector housings suffers from low drilling accuracy. Summary of the Invention

[0005] The present invention provides a drilling device for polygonal connector housings, which solves the technical problem of low drilling accuracy in existing drilling devices for connector housings.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A drilling device for a polygonal connector housing includes a frame, the frame being provided with a positioner for initial positioning of the connector housing, and a gap between the connector housing to be drilled and the positioner for displacing the connector housing to be drilled by a certain distance.

[0008] The drilling equipment for polygonal connector housings also includes a drilling assembly, which includes a drill and a drive mechanism for driving the drill to move up and down relative to the locator.

[0009] The drill includes a drill bit and a motor that drives the drill bit to rotate. The drive mechanism includes a slide that moves up and down relative to the locator. The motor is fixed to the slide. The slide is also provided with a clamping assembly that clamps and corrects the connector housing to be drilled after it has been initially positioned by the locator.

[0010] The clamping assembly includes a stationary seat fixed to the slide and a movable seat sleeved on the outside of the drill bit and sliding up and down relative to the stationary seat. The movable seat is provided with a clamping cavity for accommodating the connector housing to be drilled after being initially positioned by the positioner. The end of the movable seat away from the stationary seat is also provided with a guide to guide the connector housing into the clamping cavity. The movable seat is provided with a guide rod, the stationary seat is provided with a guide hole that cooperates with the guide rod, and an elastic element that pushes the movable seat away from the stationary seat is also provided between the stationary seat and the movable seat.

[0011] The connector housing to be drilled is fitted onto the locator, and the locator performs initial positioning of the connector housing to be drilled.

[0012] The drive mechanism drives the slide to move downward, and the drill bit moves downward together with the slide. When the guide contacts the connector housing to be drilled, which is sleeved on the positioner, the guide corrects and guides the connector housing to be drilled so that the connector housing to be drilled has the correct position relative to the clamping cavity.

[0013] The slide continues to move downwards until the connector housing to be drilled enters the clamping cavity and the guide stops moving downwards due to interference with the frame. At this point, the drill bit is not in contact with the connector housing.

[0014] The slide continues to move downwards under the elastic force of the elastic element, and the drill bit contacts the housing of the connector to be drilled and completes the drilling of the connector. After the drilling is completed, the drive mechanism drives the slide to move upwards back to the initial position.

[0015] Preferably, the guide and the moving base are an integral structure, the guide and the moving base are coaxially arranged, the moving base and the drill bit are coaxially arranged, the guide has a guide cavity, the guide cavity is frustum-shaped, the guide cavity communicates with the clamping cavity, the cross-sectional area of ​​the lower end of the guide cavity is larger than the cross-sectional area of ​​the upper end of the guide cavity, and the connector housing after being initially positioned by the positioner is completely located within the area defined by the lower end of the guide cavity.

[0016] Preferably, the inner wall of the guide and the inner wall of the moving seat are smoothly transitioned by an arc surface, and the inner wall of the guide cavity is bonded with a rubber layer to prevent damage to the connector housing.

[0017] Preferably, the stationary seat is coaxially arranged with the drill bit, and both the moving seat and the guide are provided with notches. The notches are evenly distributed along the circumference of the guide. The notches located on the moving seat communicate with the notches located on the guide. The notches located on the moving seat penetrate the side wall of the moving seat, and the notches located on the guide penetrate the side wall of the guide. The elastic element is a spring, and the elastic element is sleeved on the guide rod. The stationary seat is fixed to the slide by screws, or the stationary seat and the slide are an integral structure.

[0018] Preferably, the positioner is provided with a clearance hole to prevent interference between the positioner and the drill bit, and the outer diameter of the positioner is smaller than the outer diameter of the inner cavity of the connector housing to be drilled.

[0019] Preferably, the driving mechanism further includes a hydraulic cylinder for driving the slide seat to move. The hydraulic cylinder includes a cylinder body and a piston rod disposed on the cylinder body. The cylinder body drives the piston rod through a piston, and the slide seat is fixed to the piston rod.

[0020] Preferably, the frame is provided with a turntable, the positioner is fixed to the turntable, and there are multiple positioners evenly distributed along the circumference of the turntable. The rotation of the turntable causes the axes of the multiple positioners to be coaxial with the axis of the drill bit in sequence.

[0021] Preferably, the frame is further provided with a motor that drives the rotating shaft to rotate. The motor is fixed to the frame, and the output shaft of the motor drives the turntable to rotate. A bearing is provided between the turntable and the frame.

[0022] Preferably, the drilling apparatus for polygonal connector housings further includes a feeding assembly that supplies the connector housing to be drilled to the positioner.

[0023] Preferably, the feeding assembly includes a hopper, in which connector housings to be drilled are sequentially placed. The hopper includes a discharge port, and the connector housings to be drilled within the hopper are fitted onto the positioner through the discharge port. The feeding assembly further includes a control mechanism for controlling the opening or closing of the discharge port. The control mechanism includes a hopper door for closing the discharger, and a driver for controlling the opening or closing of the discharge door. The feeding assembly also includes a controller, and the driver is controlled by the controller. The turntable is equipped with a trigger. When the positioner is directly below the discharge port, the trigger sends a signal to the controller, which controls the hopper door to open. The connector housings to be drilled within the hopper are fitted onto the positioner under their own weight.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] This solution uses a positioner to initially position the connector housing to be drilled, leaving a certain gap between them. This design allows for minor displacement adjustments to the connector housing after initial positioning, providing a foundation for subsequent precise calibration and clamping. The clamping component in the drilling assembly achieves dynamic calibration of the connector housing through the cooperation of a stationary seat and a moving seat. When the slide moves downward, the guide first contacts the connector housing. Through the shape and position design of the guide, the position of the connector housing is forcibly calibrated to ensure it has the correct positional relationship relative to the clamping cavity. This calibration method significantly reduces the tedious process of adjusting the position of traditional fixtures, improves the initial accuracy of drilling, and thus improves drilling precision.

[0026] The elastic element and guide rod structure between the stationary and moving seats ensure the smoothness and controllability of the clamping process. The elastic element provides cushioning in the initial clamping stage, preventing damage to the connector housing from hard contact, while the cooperation between the guide rod and the guide hole ensures the precise vertical movement of the moving seat. This design not only improves clamping stability but also creates conditions for precise drilling by the drill bit.

[0027] After clamping, the slide continues to move downwards, and the drill bit begins to contact the connector housing and drill. Because the clamping assembly has ensured the precise position of the connector housing, the drill bit can complete the drilling along a preset path, avoiding drilling deviations caused by clamping errors in traditional equipment and improving drilling accuracy.

[0041] The specific embodiments shown below are intended to describe various configurations of the subject matter of the invention and are not intended to represent the only configuration in which the subject matter of the invention can be practiced. The specific embodiments include particular details intended to provide a thorough understanding of the subject matter of the invention. However, it will be clear and apparent to those skilled in the art that the subject matter of the invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0042] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0043] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0044] Reference Figures 1 to 7As shown, a drilling device for a polygonal connector housing includes a frame 1, wherein the frame 1 is provided with a positioner 11 for initial positioning of the connector housing, and there is a gap 111 between the connector housing to be drilled and the positioner 11, which allows the connector housing to be drilled to be displaced by a certain distance.

[0045] Understandably, the positioner 11 can be a positioning post. The cross-sectional shape of the positioner 11 is suitable for the inner cavity shape of the connector housing to be drilled. After the connector housing to be drilled is fitted onto the positioning post, the inner wall of the connector housing to be drilled does not contact the side wall of the positioning post. The space between the inner wall of the connector housing to be drilled and the side wall of the positioning post is the gap 111, so that the connector housing to be drilled can be adjusted in the horizontal direction.

[0046] The drilling equipment for the polygonal connector housing also includes a drilling assembly 2, which includes a drill 21 and a drive mechanism 22 for driving the drill 21 to move up and down relative to the positioner 11.

[0047] The drill 21 includes a drill bit 211 and a motor 212 that drives the drill bit 211 to rotate. During drilling, the motor 212 drives the drill bit 211 to rotate to achieve drilling. The output shaft of the motor 212 can be equipped with a chuck, and the drill bit 211 is held by the chuck. The drive mechanism 22 includes a slide 221 that moves up and down relative to the positioner 11. The motor 212 is fixed to the slide 221. The slide 221 is also provided with a clamping assembly 3. The clamping assembly 3 clamps and corrects the connector housing to be drilled after it has been initially positioned by the positioner 11.

[0048] Reference Figures 1 to 7 As shown, the clamping assembly 3 includes a stationary seat 31 fixed to the slide 221 and a movable seat 32 sleeved on the outside of the drill bit 211 and sliding up and down relative to the stationary seat 31. The movable seat 32 is provided with a clamping cavity 321 for accommodating the connector housing to be drilled after being initially positioned by the positioner 11. The end of the movable seat 32 away from the stationary seat 31 is also provided with a guide 322 for guiding the connector housing into the clamping cavity 321. The movable seat 32 is provided with a guide rod 323. The stationary seat 31 is provided with a guide hole that cooperates with the guide rod 323. An elastic element 33 is also provided between the stationary seat 31 and the movable seat 32 to push the movable seat 32 away from the stationary seat 31.

[0049] Understandably, the shape of the clamping cavity 321 matches the shape of the connector housing to be drilled. After the connector housing to be drilled enters the clamping cavity 321, the side wall of the clamping cavity 321 contacts the outer wall of the connector housing to be drilled, thereby achieving clamping and position correction of the connector housing to be drilled.

[0050] Understandably, a wear-resistant layer can be provided on the sidewall of the clamping cavity 321 to extend the service life of the moving seat 32. The clamping assembly 3 does not rotate with the drill bit 211 during operation.

[0051] Understandably, a rolling bearing 14 can be installed between the stationary seat 31 and the output shaft of the motor 212. By installing the rolling bearing 14, the stationary seat 31 has a higher coaxiality with respect to the output shaft of the motor 212, thereby improving the positional accuracy of the clamping cavity 321.

[0052] The connector housing to be drilled is fitted onto the positioner 11, and the positioner 11 performs initial positioning of the connector housing to be drilled. After initial positioning, the connector housing to be drilled can still be displaced a certain distance in the horizontal direction. The function of this initial positioning is to ensure that the connector housing to be drilled has the correct position range relative to the guide 322, so that the guide 322 can correctly guide the connector housing to be drilled into the clamping cavity 321.

[0053] The drive mechanism 22 drives the slide 221 to move downward, and the drill bit 211 moves downward together with the slide 221. When the guide 322 contacts the connector housing to be drilled that is sleeved on the positioner 11, the guide 322 corrects and guides the connector housing to be drilled so that the connector housing to be drilled has the correct position relative to the clamping cavity 321.

[0054] Since the stationary seat 31 is mounted on the slide 221 and the moving seat 32 is slidably connected to the stationary seat 31, the position of the stationary seat 31 relative to the drill bit 211 is determined. Therefore, the position of the moving seat 32 relative to the drill bit 211 is also determined, which makes the position of the clamping cavity 321 relative to the drill bit 211 determined. After the drilling connector housing enters the clamping cavity 321, its position relative to the drill bit 211 is determined, which effectively improves the drilling accuracy.

[0055] The slide 221 continues to move downward until the connector housing to be drilled enters the clamping cavity 321 and the guide 322 interferes with the frame 1 and stops moving downward. At this time, the drill bit 211 is not in contact with the connector housing. When the slide 221 is in this position, the motor 212 can be started to drive the drill bit 211 to rotate, or the drill bit 211 can remain in a rotating state.

[0056] The slide 221 continues to move downward under the elastic force of the elastic element 33, and the drill bit 211 contacts the housing of the connector to be drilled and completes the drilling of the connector. After the drilling is completed, the drive mechanism 22 drives the slide 221 to move upward and return to the initial position.

[0057] Reference Figures 5 to 7As shown, in some embodiments, the guide 322 and the moving base 32 are an integral structure, the guide 322 and the moving base 32 are coaxially arranged, the moving base 32 and the drill bit 211 are coaxially arranged, the guide 322 has a guide cavity 324, the guide cavity 324 is frustum-shaped, the guide cavity 324 communicates with the clamping cavity 321, the cross-sectional area of ​​the lower end of the guide cavity 324 is larger than the cross-sectional area of ​​the upper end of the guide cavity 324, and the connector housing after being initially positioned by the positioner 11 is completely located in the area defined by the lower end of the guide cavity 324.

[0058] Understandably, the guide cavity 324 is truncated pyramidal in shape. When the guide cavity 324 contacts the connector housing to be drilled, the force applied to the connector housing to be drilled is divided into two components. One component pushes the connector housing to be drilled to move horizontally, pushing the connector housing to be drilled to the correct position, that is, the position corresponding to the clamping cavity 321.

[0059] In some embodiments, the inner wall of the guide 322 and the inner wall of the moving seat 32 are smoothly transitioned by an arc surface, and the inner wall of the guide cavity 324 is bonded with a rubber layer to prevent damage to the connector housing.

[0060] In some embodiments, the stationary seat 31 is coaxially arranged with the drill bit 211, and both the moving seat 32 and the guide 322 are provided with notches 325. The notches 325 are evenly distributed along the circumference of the guide 322. The notches 325 located in the moving seat 32 communicate with the notches 325 located in the guide 322. The notches 325 located in the moving seat 32 penetrate the side wall of the moving seat 32, and the notches 325 located in the guide 322 penetrate the side wall of the guide 322. The elastic element 33 is a spring, and the elastic element 33 is sleeved on the guide rod 323. The stationary seat 31 is fixed to the slide 221 by screws, or the stationary seat 31 and the slide 221 are an integral structure.

[0061] The outer edge of the connector housing to be drilled can extend out of the stationary seat 31 through the notch 325 so that the side wall of the connector housing to be drilled can properly contact the side wall of the clamping cavity 321.

[0062] In some embodiments, the positioner 11 is provided with a clearance hole 112 to prevent interference between the positioner 11 and the drill bit 211, and the outer diameter of the positioner 11 is smaller than the outer diameter of the inner cavity of the connector housing to be drilled.

[0063] The diameter of the relief hole 112 is larger than the diameter of the drill bit 211, so that the drill bit 211 can extend into the relief hole 112.

[0064] In some embodiments, the drive mechanism 22 further includes a hydraulic cylinder for driving the slide 221 to displacement. The hydraulic cylinder includes a cylinder body 222 and a piston rod 223 disposed on the cylinder body 222. The cylinder body 222 drives the piston rod 223 through a piston, and the slide 221 is fixed to the piston rod 223.

[0065] In some embodiments, the cylinder body 222 can be fixed to the ground, or the cylinder body 222 can be fixed to the frame 1.

[0066] Reference Figures 1 to 4 As shown, in some embodiments, the frame 1 is provided with a turntable 12, the positioner 11 is fixed to the turntable 12, and there are multiple positioners 11. The multiple positioners 11 are evenly distributed along the circumference of the turntable 12, and the turntable 12 rotates so that the axes of the multiple positioners 11 are sequentially coaxial with the axis of the drill bit 211.

[0067] Understandably, the connector housing to be drilled can be fitted onto each positioner 11, and then the turntable 12 can be rotated to make the connector housing to be drilled correspond to the drill bit 211 in sequence, thereby performing drilling operations on the connector housing to be drilled.

[0068] In some embodiments, the frame 1 is further provided with a motor 13 that drives the rotating shaft to rotate. The motor 13 is fixed to the frame 1, and the output shaft of the motor 13 drives the turntable 12 to rotate. A bearing 14 is provided between the turntable 12 and the frame 1.

[0069] In some embodiments, in order to improve the rotational accuracy of the turntable 12, the motor 13 can be a stepper motor 212 or a servo motor 212.

[0070] In some embodiments, the drilling apparatus for polygonal connector housings further includes a feeding assembly 4 that supplies the connector housing to be drilled to the positioner 11.

[0071] In some embodiments, the feeding assembly 4 includes a hopper 41, in which the connector housing to be drilled is sequentially placed. The hopper 41 includes a discharge port, and the connector housing to be drilled within the hopper 41 is fitted onto the positioner 11 through the discharge port. The feeding assembly 4 also includes a control mechanism 42 for controlling the opening or closing of the discharge port. The control mechanism 42 includes a door for closing the discharge port and a driver for controlling the door to open or close the discharged material. The feeding assembly 4 also includes a controller, and the driver is controlled by the controller. The turntable 12 is equipped with a trigger 43. When the positioner 11 is located directly below the discharge port, the trigger 43 sends a signal to the controller, which controls the door to open. The connector housing to be drilled within the hopper 41 is fitted onto the positioner 11 under its own weight.

[0072] In some embodiments, the hopper 41 is vertically arranged, and the connector housing to be drilled located in the hopper 41 is discharged from the discharge port under the action of gravity.

[0073] In some embodiments, the hopper door slides horizontally relative to the hopper 41.

[0074] In some embodiments, the driver can be an electromagnet. The controller controls the electromagnet to be energized or de-energized. The electromagnet drives the displacement of the bin door. When the bin door corresponds to the discharge device, the discharge port is closed, and the connector shell to be drilled in the bin 41 cannot be discharged. When the bin door and the discharge port are misaligned, the discharge port is opened, and the connector shell to be drilled in the bin 41 can be discharged from the discharge port. The connector shell to be drilled discharged from the discharge port is fitted onto the positioner 11 under the action of gravity, realizing the initial positioning of the connector shell to be drilled.

[0075] The technical solution of the present invention and its corresponding details have been described above. It is understood that the above description is only some implementation schemes of the technical solution of the present invention, and some details may be omitted in the specific implementation.
