Abstract

This utility model discloses a metal housing oblique hole processing device, including a processing device body. The processing device body includes a housing base. A column is welded and fixed to the tail end of the upper surface of the housing base. A movable mounting seat is provided on the front surface of the column. Two clamping plates, a second clamping plate and a first clamping plate, are respectively installed at both ends of the upper surface of the housing base through two push electric cylinders. By designing an angle-adjustable clamping mechanism, the angle of drilling can be adjusted by adjusting the lower support plates inside the second clamping plate and the first clamping plate according to different metal housings when processing oblique holes at different angles. This makes the two lower support plates inside the second clamping plate and the first clamping plate at the same support angle. When the two ends of the metal housing are placed inside the second clamping plate and the first clamping plate respectively and the lower support plates are lifted, the clamping electric cylinder moves to drive the upper pressure plate to move down and press tightly against the surface of the metal housing to reinforce the drilling. Therefore, the angle adjustment is convenient during drilling and it is suitable for processing oblique holes at different angles on different metal housings.

When metal housings need to be machined with oblique holes during processing and production, they are usually machined by processing equipment, and the existing processing equipment is the equipment used to machine oblique holes in metal housings.

[0003] Existing processing devices, when machining oblique holes in metal housings, directly insert the end of the metal housing into the clamping plate at a certain angle for clamping at a fixed angle. This is problematic when machining oblique holes at different angles for different metal housings. Adjusting the internal installation angle of the clamping plate is inconvenient, and even direct closure can cause clamping difficulties, leading to errors in the machined oblique holes. This affects the ease of adjusting the internal installation angle of the clamping plate when machining oblique holes at different angles for different metal housings. Therefore, this invention proposes a metal housing oblique hole machining device. Utility Model Content

[0024] A lead screw 107 rotates inside the column 108. A lifting reduction motor 109 is fixed to the end of the lead screw 107 on the upper surface of the column 108. The end of the movable mounting base 104 extends into the interior of the column 108 and matches the threaded structure on the outer surface of the lead screw 107. A servo motor 106 is fixedly mounted on the upper surface of the movable mounting base 104. A drill bit 105 is mounted on the lower surface of the movable mounting base 104 via the mounting base. The main body 100 of the processing device also includes:

[0025] An angle-adjustable clamping mechanism is provided, including a clamping component located at the top of the inner side of clamping plate 2 102 and clamping plate 103, a support and lifting component located at the bottom of the inner side of clamping plate 2 102 and clamping plate 103, a limiting lifting component located on the inner side of clamping plate 2 102 and the inner outer side of clamping plate 103, and the top of the limiting lifting component and the support and lifting component being connected by a connecting pin. An adjustment component is provided on the lower surface of the limiting lifting component. When the processing device body 100 processes oblique holes of different angles on different metal housings, the angle-adjustable clamping mechanism can be used to process the metal housings at different angles, facilitating adjustment and installation for processing and use.

[0026] In order to facilitate the installation of the metal housing at a certain angle and then tighten and fix it again through the clamping assembly, in this embodiment, preferably, the clamping assembly includes a clamping electric cylinder 1021 fixedly installed at both ends of the upper surface of the second clamping plate 102 and the first clamping plate 103 by screws. The upper top of the inner end of the second clamping plate 102 and the first clamping plate 103 are provided with an upper pressure plate 1022, and the end of the clamping electric cylinder 1021 is connected to the upper surface end of the upper pressure plate 1022 through a rotating shaft. After the metal housing is installed at a certain angle inside the second clamping plate 102 and the first clamping plate 103, the movement of the clamping electric cylinder 1021 drives the upper pressure plate 1022 to move down and clamp it.

[0027] In order to facilitate the angled hole machining of the metal housing by means of the support and lifting assembly, in this embodiment, preferably, the support and lifting assembly includes a lower support plate 1023 disposed at the bottom of the inner end of the second clamping plate 102 and the first clamping plate 103, corresponding to the upper pressure plate 1022, and the two ends of the lower surface of the lower support plate 1023 are connected to the inner bottom of the second clamping plate 102 and the first clamping plate 103 by a rotating shaft. Both ends of the lower surface of the lower support plate 1023 are provided with support sliding grooves 1029, and support sliding plates 1028 slide inside the support sliding grooves 1029.

[0028] In order to facilitate the adjustment of the installation angle of the lower support plate 1023 by means of the limiting lifting component, in this embodiment, preferably, the limiting lifting component includes a limiting moving groove 1027 formed on one side of the bottom end of the second clamping plate 102 and the other side of the bottom end of the first clamping plate 103. The top end of the limiting moving groove 1027 is limited by a limiting inclined moving plate 1025, and the top end of the limiting inclined moving plate 1025 is connected to the bottom end of the support slide plate 1028 by a connecting pin. When the limiting inclined moving plate 1025 is lifted, it causes the support slide plate 1028 to slide inside the support sliding groove 1029, so that the angle between the support slide plate 1028 and the limiting inclined moving plate 1025 changes, so that the lower support plate 1023 is at the installation angle.

[0029] To facilitate the lifting and support adjustment of the limiting inclined moving plate 1025 via the adjustment component, in this embodiment, preferably, the adjustment component includes a trapezoidal push block 1026 that slides within one side of the limiting moving groove 1027, with the end of the trapezoidal push block 1026 contacting one side of the lower surface of the limiting inclined moving plate 1025. A threaded rod 1024 is threadedly connected to the side of the clamping plate 102 and the clamping plate 103. The end of the threaded rod 1024 is connected to the interior of the trapezoidal push block 1026 via a bearing. Rotating the threaded rod 1024 allows the trapezoidal push block 1026 to move within the limiting moving groove 1027, and the trapezoidal push block 1026 presses and lifts the limiting inclined moving plate 1025, facilitating adjustment and use.

[0030] The guide support mechanism includes guide support components located at the connection points between the movable mounting base 104 and the side of the column 108 on both sides. This mechanism can stably move and adjust the movable mounting base 104, and during stable movement and adjustment, it can make the movable mounting base 104 operate more stably and perform precise drilling operations.

[0031] To facilitate stable drilling and limiting of the movable mounting base 104 using the guide support assembly, in this embodiment, preferably, the guide support assembly includes guide support plates 1041 welded and fixed to both sides of the movable mounting base 104. Support grooves 1042 are provided on both sides of the column 108. Support sliders 1043 slide inside the support grooves 1042, and the ends of the support sliders 1043 and guide support plates 1041 are fixed with bolts. This allows the guide support plates 1041 to move when the movable mounting base 104 moves, and the guide support plates 1041 control the sliding of the support sliders 1043 within the support grooves 1042, thus ensuring stable support during the guided movement and drilling of the movable mounting base 104.

[0032] The clamping electric cylinder 1021 in this utility model is model number HTB.

[0033] The working principle and usage process of this utility model are as follows: Before using this metal housing oblique hole processing device, the metal housing is first installed at a certain angle according to the required oblique hole angle. When the metal housing is installed at a certain angle, the lower support plate 1023 inside the clamping plate 2 102 and clamping plate 103 is adjusted. A wrench can be engaged with the outer surface of the threaded rod 1024 and screwed outward to drive the trapezoidal push block 1026 to move in a limited position on one side inside the limiting moving groove 1027. When the trapezoidal push block 1026 moves in a limited position, it contacts the side of the limiting inclined moving plate 1025. 1025 is pressed and moved, and the surfaces of the limiting inclined moving plate 1025 and the trapezoidal push block 1026 are smooth, and the friction is negligible. When the limiting inclined moving plate 1025 moves, it drives the support slide plate 1028 to slide inside the support sliding groove 1029 and change the angle of the end of the limiting inclined moving plate 1025. At the same time, the two ends of the lower support plate 1023 rotate through the pivot, and the inner side of the lower support plate 1023 is lifted up to a certain installation angle. The same operation is repeated to lift the outer side of the lower support plate 1023 inside the clamp 103 to a certain angle, so that the two lower support plates 1023 are at the same tilt angle.

[0034] The clamping plates 102 and 103 are adjusted to the same width as the metal housing by pushing the cylinder. The two ends of the metal housing are respectively embedded into the lower inner surfaces of the clamping plates 102 and 103, which contact the surface of the lower support plate 1023. The two clamping electric cylinders 1021 move simultaneously, causing the upper pressure plate 1022 to move down and press against the surface of the metal housing. When the upper pressure plate 1022 moves down, it rotates adaptively to make close contact with the upper surface of the metal housing and presses it, thus facilitating the reinforcement and installation of the metal housing. Therefore, it is convenient to adjust when the processing device body 100 reinforces different angled holes for different metal housings, improving the convenience of angle adjustment when processing different angled holes of the processing device body 100.

[0035] Then, when the main body 100 of the processing device is processing, the clamping plate 102 and the clamping plate 103 fix the metal housing at a certain processing angle. The lifting and reducing motor 109 drives the lead screw 107 to rotate. When the lead screw 107 rotates, it drives the movable mounting base 104 to move down. When the movable mounting base 104 moves down, the servo motor 106 drives the drill bit 105 to rotate. The drill bit 105 rotates and contacts the surface of the metal housing to drill a hole, thus facilitating the processing of the oblique hole in the metal housing.

[0036] Finally, when the main body 100 of the processing device is drilling, the movable mounting base 104 moves and simultaneously drives the guide support plate 1041 to move. The end of the guide support plate 1041 drives the support slider 1043 to move inside the support groove 1042. This allows the movable mounting base 104 to be guided and supported by the guide support plate 1041 and the support slider 1043 when it moves, making the movable mounting base 104 more stable and supportive during drilling, enabling precise drilling operations and improving the stability of the guide support of the movable mounting base 104 by the main body 100 of the processing device when machining oblique holes in metal housings.

[0037] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
