Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for processing half-cut through holes in the side wall of a notebook casing. Background Technology

[0002] In the field of laptop casing manufacturing, customers typically require grooves 41, 200 mm long and 3 mm wide, to be machined on the four sides of the casing, and through holes 42, 45 mm long and 2.5 mm wide, to be made in the grooves 41 (e.g., ...). Figure 1 (As shown).

[0003] Current technology primarily employs a method of first forming grooves with a punch press, and then milling through holes into the grooves using CNC cutting tools. During processing, the outer shell is fixed to the back by a sealing ring. However, this method has significant drawbacks: First, the shell deforms considerably after stamping, while the CNC attachment point is located on the back, and the processing point is on the side, causing the side of the shell to vibrate easily during processing, leading to dimensional deviations or surface damage. Second, the sidewall space is narrow and curved, making it difficult for the sealing ring to effectively adhere within such a space, resulting in poor fixation and insufficient processing stability. Furthermore, the development cost of dedicated molds is high, and molds used for machining slender grooves are prone to wear and frequent maintenance, affecting production efficiency and product consistency. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a jig for machining half-cut through holes in the sidewalls of a laptop casing, which enables precise positioning and stable clamping.

[0005] The main contents of this utility model include: a base component, which includes a base plate and a support base plate vertically disposed on the base plate. The support base plate is used to vertically support the back of the shell and support the side of the shell to be processed. A side clamping mechanism is disposed on the base plate and located on the front side of the support substrate, for pressing the outer shell onto the support substrate from the horizontal direction; A machining surface clamping mechanism is disposed above the support base plate to press the side of the housing to be machined from the vertical direction and to provide a clearance passage for the machining tool.

[0006] Preferably, the upper surface of the support substrate is provided with an upwardly protruding support platform for supporting the side of the outer shell to be processed; the front surface of the support substrate is provided with a forward-protruding positioning platform for adapting to the back contour of the outer shell.

[0007] Preferably, the front side of the supporting substrate is further provided with a positioning structure, the positioning structure including positioning blocks on the left and right sides of the supporting substrate, the positioning blocks forming a gap with the positioning platform, the gap being adapted to the arc-shaped edges on the left and right sides of the outer shell, for lateral positioning of the outer shell.

[0008] Preferably, the side clamping mechanism includes a lateral pressure plate and a transverse drive unit for driving the lateral pressure plate to move horizontally.

[0009] Preferably, the length of the lateral pressure plate does not exceed the arc-shaped edges on the left and right sides of the outer shell, so as to ensure that its pressing range is the planar area of ​​the outer shell; the pressing action position of the lateral pressure plate is located on the upper part of the support base plate.

[0010] Preferably, the lateral drive unit includes two symmetrically arranged telescopic cylinders for synchronously driving the lateral pressure plate.

[0011] Preferably, the machining surface clamping mechanism includes an upper pressure plate and a lifting drive unit for driving the upper pressure plate to move vertically up and down. The upper pressure plate is located on the upper end surface of the side of the housing to be machined, and a tool avoidance channel is provided thereon.

[0012] Preferably, the tool avoidance channel includes a guide section and a processing section that are connected vertically. The cross-section of the guide section is funnel-shaped and used to guide the tool. The cross-section of the processing section is adapted to the shape of the groove to be processed, so as to expose the area to be processed and press down the rest.

[0013] Preferably, the lifting drive unit is fixed to the back of the support base plate, and includes two symmetrically arranged lifting cylinders for synchronously driving the upper pressure plate to lift.

[0014] The beneficial effects of this utility model are as follows: the fixture adopts a coordinated design of base components, side wall clamping mechanism and processing surface clamping mechanism, which realizes accurate positioning and multi-directional clamping of the shell, avoids vibration and displacement during processing, and significantly improves processing accuracy and product consistency; by completing half shearing and through hole processing in one go, the error caused by multiple clamping is reduced, and the development and maintenance costs of two sets of high-cost molds are saved, thus reducing production costs.

[0016] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0017] like Figure 2-3 As shown, this application proposes a jig for processing half-cut through holes in the side wall of a laptop shell, which includes a base component 1, a side clamping mechanism 2, and a processing surface clamping mechanism 3, so as to achieve precise positioning and stable clamping of the laptop shell and avoid damage to the shell during processing.

[0018] like Figure 2-4 As shown, the base component 1 includes a base plate 11 and a support base plate 12 vertically fixed to the upper surface of the base plate 11. The front side of the support base plate 12 is used to fit against the back of the notebook casing, and the upper end surface of the support base plate 12 is used to support the side of the notebook casing to be processed, thereby achieving vertical support for the casing and providing a support base surface for the processing surface of the casing.

[0019] like Figure 2-4 As shown, the upper surface of the support substrate 12 is integrally formed with an upwardly protruding support platform 121. The contour of the support platform 121 is adapted to the arc-shaped structure of the side of the notebook shell to be processed, and can fit the bottom of the side of the shell, avoiding deformation caused by uneven local stress on the side of the shell. The front surface of the support substrate 12 is integrally formed with a forward-protruding positioning platform 122. The shape of the positioning platform 122 is adapted to the arc-shaped contour of the back of the notebook shell, and can fit tightly against the back of the shell to define the placement position of the shell and improve the support stability.

[0020] like Figure 2-4 As shown, further, the front side of the support substrate 12 is also provided with a positioning structure, which includes positioning blocks 123 on the left and right sides of the support substrate 12. A gap is formed between the positioning blocks 123 and the positioning stage 122. The width of the gap is adapted to the thickness of the arc-shaped edges on the left and right sides of the notebook shell. The arc-shaped edges on the left and right sides of the shell can be embedded in the gap to achieve precise positioning of the shell in the horizontal direction and prevent the shell from shifting left and right during the processing.

[0021] like Figure 2-4As shown, the side clamping mechanism 2 is fixed on the base plate 11 and located on one side of the front of the support substrate 12. It is used to press the notebook shell onto the front of the support substrate 12 from the horizontal direction to prevent the shell from shaking back and forth during the processing.

[0022] like Figure 2-4 As shown, the side clamping mechanism 2 includes a lateral pressure plate 21 and a transverse drive unit 22 for driving the lateral pressure plate 21 to move horizontally. The horizontal length of the lateral pressure plate 21 does not exceed the arc-shaped edges on the left and right sides of the notebook casing, ensuring that the pressing area of ​​the lateral pressure plate 21 only covers the planar area of ​​the casing, avoiding deformation of the casing edges due to contact between the lateral pressure plate 21 and the arc-shaped edges. Preferably, the pressing height of the lateral pressure plate 21 is close to the upper part of the support substrate 12, that is, close to the side area of ​​the casing to be processed, to enhance the clamping stability of the processing area and reduce the impact of processing vibration on accuracy.

[0023] like Figure 2-4 As shown, the lateral drive unit 22 is used to drive the lateral pressure plate 21 to move closer to or further away from the support base plate 12 in the horizontal direction. In a specific embodiment, the lateral drive unit 22 includes two symmetrically arranged telescopic cylinders. The two telescopic cylinders are fixed to the base plate 11 by a bracket. The end of the piston rod is connected to the lateral pressure plate 21. Through the synchronous extension and retraction of the two drive cylinders, the lateral pressure plate 21 can be driven to move smoothly, so as to achieve uniform pressing of the shell and avoid deformation of the shell due to unilateral force.

[0024] like Figure 2-4 As shown, the processing surface clamping mechanism 3 is located above the support base plate 12 and is used to press the upper side surface of the notebook shell to be processed from the vertical direction, while providing a clearance channel for the processing tool to avoid interference between the tool and the fixture.

[0025] like Figure 2-5 As shown, the processing surface clamping mechanism 3 includes an upper pressure plate 31 and a lifting drive unit 32 that drives the upper pressure plate 31 to move vertically up and down. The lower surface of the upper pressure plate 31 is adapted to the upper end face of the side of the laptop shell to be processed, allowing it to fit tightly against the upper end face of the shell. A tool avoidance channel 33 is provided on the upper pressure plate 31, extending through its upper and lower surfaces. The tool avoidance channel 33 includes a guide portion 331 and a processing portion 332 that are connected vertically. The guide portion 331 has a funnel-shaped cross-section (i.e., an inverted trapezoidal structure that gradually narrows from top to bottom), used to guide the tool to accurately insert into the area to be processed during processing. The cross-section of the processing portion 332 is consistent with the shape and size of the groove to be processed on the laptop shell, exposing only the area to be processed. The remaining non-processed areas are still pressed by the upper pressure plate 31, ensuring the stability of the area around the processed area of ​​the shell and preventing deformation of the non-processed areas.

[0026] like Figure 2-5As shown, the lifting drive unit 32 is used to drive the upper pressure plate 31 to rise and fall vertically, thereby pressing and releasing the housing. In a specific embodiment, the lifting drive unit 32 includes two symmetrically arranged lifting cylinders. The synchronous extension and retraction of the two cylinders can drive the upper pressure plate to rise and fall smoothly, ensuring that the pressing force of the upper pressure plate 31 on the housing is evenly distributed. Preferably, the lifting cylinders are fixed to the back of the support base plate 12, which can effectively save fixture space.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
