Description

Technical Field

[0001] This utility model relates to the field of connector drilling and processing, specifically a connector drilling device. Background Technology

[0002] In modern electronic equipment, communication equipment, computer equipment, and aerospace equipment, connectors play a crucial role as key components for circuit connections. Female header connectors, as a common type of electrical connector, are widely used in various electronic devices to connect two parts of a circuit, enabling signal and power transmission. A female header connector consists of two parts: a female header and a male header. The female header is a set of metal strips with fixed spacing and length, typically made of copper or copper alloys, with fixing holes at both ends for fixing and connecting circuit boards. The upper surface of the female header has rows of U-shaped grooves for inserting the male header. The male header is also a set of metal tubes with fixed spacing and length, with rows of pins on its lower surface corresponding to the U-shaped grooves of the female header. When the male header is inserted into the U-shaped groove of the female header, the pins contact the metal strips in the groove, forming an electrical connection, thus enabling the connection and disconnection of the circuit.

[0003] When installing female and male connectors, holes need to be drilled in both the female and male busbars to connect wires or secure them to other components. The accuracy and efficiency of drilling directly affect the quality and production cost of the connector. Currently, common drilling methods include mechanical drilling, die-cutting drilling, and punching drilling.

[0004] Currently, the drilling position of the drilling device is fixed, but the drilling distance and number of holes are different for female connectors of different lengths. When drilling with a fixed drilling position, the position of the female connector needs to be adjusted, which can easily affect the drilling accuracy. Utility Model Content

A sliding mounting groove is provided on the mounting bracket along the sliding trajectory of the drilling unit. The middle mounting block and the rear pad are fixed by bolts, and the threaded part of the bolt slides along the sliding mounting groove.

[0011] Preferably, a first pressure spring is provided between the upper fixing plate and the intermediate mounting block along the outside of the drive shaft, and a second pressure spring is provided between the lower fixing plate and the intermediate mounting block along the outside of the drive shaft.

[0012] Preferably, the lower fixed plate is connected to a telescopic connecting rod in a circular array on its lower end, and the lower ends of the multiple telescopic connecting rods are connected to a lower pressure ring. The lower pressure ring is located at the lower end of the drilling tool, and a fourth pressure spring is provided between the lower pressure ring and the lower fixed plate along the outside of the telescopic connecting rod.

One end of the drive shaft passes through the bearing seat on one side and is connected to a second transmission wheel. The drive shaft and the bearing seat on one side are connected by a swivel ring. The second transmission wheel and the first transmission wheel are connected by a transmission belt. A through rectangular groove is provided on the mounting bracket at the position corresponding to the transmission belt. A lower triangular support block is welded and fixed to the rear end of the lower end of the middle mounting block, and the rear end face of the lower triangular support block is in contact with the mounting bracket.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) In this utility model, the position of the drilling unit can be adjusted according to the drilling position and the drilling unit can be installed according to the number of holes. When installing the drilling unit, the drive cam is moved to the upper end of the limiting middle groove inside the upper fixed frame of the drilling unit. Then, the drilling unit is moved upward so that the mounting hole on the middle mounting block is aligned with the sliding mounting groove. Then, the rear pad is placed at the rear end of the mounting bracket, and the bolt thread passes through the rear pad, the sliding mounting groove and the middle mounting block for simple fixation. Then, the drilling unit is pushed so that the drilling unit slides along the limiting of the mounting bracket until the drilling tool matches the drilling position. Then, the nut is tightened for fixation. This achieves precise positioning of the drilling unit on the mounting bracket, thereby significantly improving the drilling accuracy. It solves the problem that the drilling position of the drilling device is fixed, but the drilling distance and the number of holes are different for different length specifications of female connectors. When drilling with a fixed drilling position, the position of the female connector needs to be adjusted, which can easily affect the drilling accuracy. Moreover, the overall installation and adjustment process is simple and convenient. Users only need to adjust the position and number of drilling units according to the drilling position and number to complete the installation, which greatly reduces the difficulty of operation.

[0017] (2) In this utility model, the drive shaft and the drive cam are connected by a limiting groove and a limiting slide, so that when the drive shaft rotates, the limiting groove and the limiting slide drive drive the drive cam to rotate, thereby realizing the drilling process; and the sliding relationship between the limiting groove and the limiting slide allows the drive cam to slide along the drive shaft, thereby matching the drilling unit and realizing the driving when the drilling unit moves to different positions.

[0018] (3) In this utility model, by setting an extrusion block and a third pressure spring inside the punching tool, the waste material can be automatically ejected after punching, which improves production efficiency.

[0019] (4) In this utility model, by setting a telescopic connecting rod and a fourth pressure spring at the lower end of the lower fixed plate, the lower pressure ring first contacts the connector. As the drilling unit presses down to drill holes, the telescopic connecting rod and the fourth pressure spring are compressed, and the pressure of the lower pressure ring on the connector increases, thus ensuring the drilling stability of the connector.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figures 1-6 One embodiment provided by this utility model:

[0029] (1) Mounting bracket and drive structure:

[0030] This device includes a mounting bracket 1. A drive shaft 8 is mounted on the upper end of the front end of the mounting bracket 1 and is supported by bearing seats on both sides. The support of the bearing seats ensures the stable rotation of the drive shaft 8. A drilling unit 12 is mounted on the front end of the mounting bracket 1. Multiple drive cams 10 are mounted on the outside of the drive shaft 8 to drive the drilling unit 12 to move up and down.

[0031] A limiting groove 9 is laterally formed on the surface of the drive shaft 8. A limiting slide bar 11 is integrally connected inside the through hole of the drive cam 10. The limiting slide bar 11 matches the shape of the limiting groove 9 and is slidably connected. When the drive shaft 8 rotates, the limiting groove 9 and the limiting slide bar 11 limit the drive cam 10 to rotate, thereby realizing the drilling process. The sliding relationship between the limiting groove 9 and the limiting slide bar 11 allows the drive cam 10 to slide along the drive shaft 8, thereby matching the drilling unit 12 and realizing the drive when the drilling unit 12 moves to different positions.

[0032] A drive motor 3 is mounted on the upper rear end of the mounting bracket 1, and the output shaft of the drive motor 3 is connected to a first transmission wheel 4. One end of the drive shaft 18 passes through a bearing seat on one side and is connected to a second transmission wheel 5. The second transmission wheel 5 and the first transmission wheel 4 are connected by a transmission belt 6. A through rectangular groove 7 is provided on the mounting bracket 1 at a position corresponding to the transmission belt 6. Through the transmission relationship between the drive motor 3, the first transmission wheel 4, the second transmission wheel 5, and the transmission belt 6, the stable rotation of the drive shaft 8 is achieved, thereby driving the up and down movement of the drilling unit 12. At the same time, the design of the through rectangular groove 7 provides sufficient space for the transmission belt 6, avoiding energy loss and wear caused by friction between the transmission belt 6 and the mounting bracket 1.

[0033] (2) Installation and sliding of the drilling unit:

[0034] The drilling unit 12 includes a central mounting block 15. A sliding mounting groove 2 is provided on the mounting bracket 1 along the sliding path of the drilling unit 12. A rear pad 16 is provided at the rear end of the mounting bracket 1 along the rear end of the central mounting block 15. The central mounting block 15 and the rear pad 16 are fixed together by bolts, with the bolt threads sliding along the sliding mounting groove 2. The cooperation between the sliding mounting groove 2 and the bolts allows the drilling unit 12 to be flexibly installed and slid along the mounting bracket 1, facilitating precise adjustment by the user according to the drilling position. A lower triangular support block 17 is welded and fixed to the rear end of the lower end of the central mounting block 15. The rear end face of the lower triangular support block 17 fits against the mounting bracket 1, and the design of the lower triangular support block 17 enhances the stability of the drilling unit 12.

[0035] An upper fixing frame 13 is welded and fixed to the rear end of the upper mounting block 15. A limiting intermediate groove 14 is opened from top to bottom on the front end face of the upper fixing frame 13. The width of the limiting intermediate groove 14 is greater than the width of the drive cam 10, but slightly larger, and mainly serves as a limiting drive.

[0036] (3) Drilling of the drilling unit:

[0037] A drive shaft 18 is slidably connected within the intermediate mounting block 15. An upper fixing plate 19 is fixed to the upper end of the drive shaft 18, and fixing plates 20 are fixed to both sides of the upper end of the upper fixing plate 19. A transverse plate 21 is fixed between the two fixing plates 20, and the transverse plate 21 contacts the lower end of the drive cam 10. A lower fixing plate 23 is fixed to the lower end of the drive shaft 18, and a drilling tool 25 is mounted on the lower end of the lower fixing plate 23. Through the sliding connection between the upper fixing plate 19, the lower fixing plate 23 and the drive shaft 18, and the contact between the transverse plate 21 and the drive cam 10, the vertical movement of the drilling unit 12 is realized, providing a stable power source for the drilling operation.

[0038] A first pressure spring 22 is provided between the upper fixed plate 19 and the middle mounting block 15 along the outside of the drive shaft 18, and a second pressure spring 24 is provided between the lower fixed plate 23 and the middle mounting block 15 along the outside of the drive shaft 18. The arrangement of the first pressure spring 22 and the second pressure spring 24 causes the drilling unit 12 to move upward under the reset action of the first pressure spring 22 and the second pressure spring 24 when the protrusion of the drive cam 10 rotates towards the arc portion, thereby completing the drilling.

[0039] (4) Lower pressure ring and waste disposal:

[0040] A telescopic connecting rod 29 is connected in a circular array to the lower outer end of the lower fixing plate 23. The lower ends of multiple telescopic connecting rods 29 are connected to a pressure ring 28, which is located below the drilling tool 25. A fourth pressure spring 30 is provided between the pressure ring 28 and the lower fixing plate 23 along the outside of the telescopic connecting rods 29. The cooperation between the pressure ring 28 and the fourth pressure spring 30 ensures stable downward pressure during drilling, making the connector more stable during the drilling process.

[0041] A pressing block 27 is provided at the lower end of the punching tool 25, and a third pressure spring 26 is provided at the upper end of the pressing block 27 inside the punching tool 25. The pressing block 27 and the third pressure spring 26 can eject the waste material from the punching tool 25 after punching, further improving production efficiency.

[0042] Working principle: This device works in conjunction with the female connector fixing mechanism and the worktable; after the female connector is fixed, the position of the punching unit 12 is adjusted according to the punching position and the punching unit 12 is installed according to the number of punches.

[0043] When installing the drilling unit 12, first move the drive cam 10 so that the drive cam 10 is located at the upper end of the limiting middle groove 14 inside the upper fixing bracket 13 of the drilling unit 12. Then move the drilling unit 12 upward so that the mounting hole on the middle mounting block 15 is aligned with the position of the sliding mounting groove 2. Then place the rear pad 16 at the rear end of the mounting bracket 1. Use the screw part of the bolt to pass through the rear pad 16, the sliding mounting groove 2 and the middle mounting block 15, and then use the nut to fix it simply, without tightening it. Then push the drilling unit 12 so that the drilling unit 12 slides along the limiting of the mounting bracket 1 until the drilling tool 25 matches the drilling position, and then tighten the nut to fix it.

[0044] The drive motor 3 drives the first transmission wheel 4 to rotate, which in turn drives the drive shaft 8 to rotate through the transmission relationship between the first transmission wheel 4, the second transmission wheel 5, and the transmission belt 6. The drive shaft 8 and the drive cam 10 are connected by the limiting groove 9 and the limiting slide 11, which in turn drives the drive cam 10 to rotate. When the arc-shaped part of the drive cam 10 rotates towards the protruding part, the drive cam 10 drives the drilling unit 12 to move downward, the first pressure spring 22 is compressed, and the second pressure spring 24 is extended, thus drilling. When the protruding part of the drive cam 10 rotates towards the arc-shaped part, under the reset action of the first pressure spring 22 and the second pressure spring 24, the drilling unit 12 moves upward, thus completing the drilling.

[0045] The pressure ring 28 first contacts the connector. As the punching unit 12 punches, the telescopic connecting rod 29 and the fourth pressure spring 30 are compressed, and the pressure of the pressure ring 28 on the connector increases. When the punching tool 25 contacts the connector, it punches and punches. The extrusion block 27 inside the punching tool 25 contacts the connector, and the third pressure spring 26 is compressed. When the punching is completed, the intermediate waste material loses its connection with the connector, and the third pressure spring 26 resets and pushes the extrusion block 27 to output the waste material.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
