Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for mechanical processing, and more specifically, to an auxiliary tooling for drilling holes in the reinforcing ribs of an upper sliding door. Background Technology

[0002] The reinforcing ribs of sliding doors play a crucial role in enhancing the structural strength and stability of the door. These ribs have a Z-shaped structure, and drilling holes in them is a common process in manufacturing. However, existing methods for drilling these reinforcing ribs in sliding doors have several problems:

[0003] 1. The product is relatively long, with many round holes, and relatively few holes of the same diameter;

[0004] 2. Small batch sizes require the development of stamping dies for production, which increases costs.

[0005] 3. Using CNC machine tools results in excessively high processing costs per product, which is detrimental to product production.

[0006] 4. When fitters use bench drills for direct machining, the accuracy of hole position cannot be guaranteed, resulting in low production efficiency. Utility Model Content

[0007] Based on the above-mentioned technical problems, this utility model proposes an auxiliary tooling for drilling holes in the reinforcing ribs of an upper sliding door.

[0008] A drilling auxiliary tooling for the reinforcing ribs of a sliding door includes:

[0009] The slide rail assembly includes a transverse slide rail and a longitudinal slide rail. The two ends of the transverse slide rail are supported by a slide rail fixing bracket. Two transverse sliders are provided on the transverse slide rail. The longitudinal slide rail is installed on the transverse sliders and is set perpendicular to the transverse slide rail. A longitudinal slider is installed on the longitudinal slide rail.

[0010] The clamping assembly includes two support blocks, left and right, which are respectively mounted on two longitudinal sliders. The workpiece to be processed is mounted between the two support blocks with the surface to be processed facing upwards. A drilling fixture is set on the surface to be processed, and multiple through pre-set holes are set on the drilling fixture. Both ends of the drilling fixture are respectively fixed on the two support blocks.

[0011] A bench drill is mounted on a bench drill support frame, the height of which is adjustable. The bench drill is located in the middle of a transverse slide rail and is equipped with replaceable drill bits that match preset holes on a drilling fixture.

[0012] Furthermore, the top of the support block is provided with a mounting hole, and both ends of the drilling fixture are provided with pin holes corresponding to the mounting holes, so that the drilling fixture can be fixed between the two support blocks by fixing pins.

[0013] Furthermore, the lower two ends of the drilling fixture are provided with right-angle limiting edges on the same side. The two ends of one side of the workpiece are clamped at the right-angle limiting edges, and the other side of the workpiece is pressed and limited by quick clamps. The quick clamps are fixed to the side of the support block.

[0014] Beneficial effects:

[0015] 1. Improve drilling accuracy: The slide rail assembly enables precise positioning of the clamping assembly. The drilling jig serves as the positioning reference for drilling and firmly fixes the workpiece, effectively preventing displacement of the workpiece and drilling jig during the drilling process. This ensures accurate drilling of the hole position, improves the drilling accuracy of the upper sliding door reinforcing rib, and enhances product quality.

[0016] 2. Improved processing efficiency: This tooling can quickly position and fix the workpiece, reducing the time for manual positioning and adjustment. At the same time, the replaceable drill bit and flexible position adjustment mean that when processing upper sliding door reinforcing ribs of different specifications, there is no need to frequently change equipment or make complex adjustments, which improves processing efficiency and meets the needs of large-scale production.

[0017] 3. Enhanced adaptability: The height of the bench drill support frame is adjustable, which can adapt to the processing needs of workpieces of different thicknesses; at the same time, the design of the slide rail assembly and clamping assembly allows the tooling to be flexibly adjusted to adapt to the upper sliding door reinforcing ribs of different sizes and shapes, enhancing the versatility and adaptability of the tooling and reducing production costs.

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] like Figures 1-5 The auxiliary tooling for drilling reinforcing ribs of a sliding door shown consists of three main parts: a slide rail assembly, a clamping assembly, and a bench drill.

[0026] The slide rail assembly includes a transverse slide rail 1 and a longitudinal slide rail 6, which is the key part of the entire fixture to achieve flexible positioning. The two ends of the transverse slide rail 1 are supported by the slide rail fixing frame 2 to ensure the stability and levelness of the transverse slide rail 1. Two transverse sliders 5 are provided on the transverse slide rail 1. These two transverse sliders 5 can slide freely on the transverse slide rail 1, thereby realizing the position adjustment of the longitudinal slide rail 6 in the transverse direction. The longitudinal slide rail 6 is installed on the transverse sliders 5 and is set perpendicular to the transverse slide rail 1, providing a moving track for the longitudinal slider 7. The longitudinal slider 7 is installed on the longitudinal slide rail 6 and can slide on the longitudinal slide rail 6, thereby driving the clamping assembly installed on it to move in the longitudinal direction. Through the cooperation of the transverse sliders 5 and the longitudinal sliders 7, the clamping assembly can be flexibly moved to the required position in the plane, providing a basis for position adjustment for precise drilling.

[0027] The clamping assembly includes two support blocks 8 on the left and right sides, which are respectively mounted on two longitudinal sliders 7 and move with the longitudinal sliders 7. The workpiece 4 to be processed is mounted between the two support blocks 8 with the surface to be processed facing upwards to facilitate drilling. A drilling fixture 9 is set on the surface to be processed, and multiple through pre-set holes 901 are set on the drilling fixture 9. These pre-set holes 901 serve as positioning references for drilling to ensure accurate drilling position. The two ends of the drilling fixture 9 are respectively fixed on the two support blocks 8 to ensure the stability of the drilling fixture 9 during the processing.

[0028] Fixing the drilling fixture 9: The top of the support block 8 is provided with a mounting hole, and both ends of the drilling fixture 9 are provided with pin holes 13 corresponding to the mounting holes. The drilling fixture 9 is fixed between the two support blocks 8 by fixing pins 12. This fixing method is simple and reliable, and can ensure that the relative position between the drilling fixture 9 and the support block 8 is fixed, avoiding displacement of the drilling fixture 9 during the drilling process, thereby ensuring the drilling accuracy.

[0029] Fixing of workpiece 4: The lower two ends of the drilling fixture 9 are provided with right-angle limiting clips 902 on the same side. The right-angle limiting clips 902 are L-shaped. The two ends of one side of the workpiece 4 are clamped at the right-angle limiting clips 902, which can initially position the workpiece 4. The other side of the workpiece 4 is pressed and limited by the quick clamp 10. The quick clamp 10 is fixed to the side of the support block 8. In this way, the workpiece 4 can be firmly fixed on the drilling fixture 9 to prevent the workpiece 4 from moving during the drilling process, and further improve the drilling accuracy and quality.

[0030] The bench drill 3 is mounted on the bench drill support frame 11, located in the middle of the transverse slide rail 1. The bench drill 3 is equipped with replaceable drill bits, which match the preset holes 901 on the drilling fixture 9. During drilling, the drill bit drills the workpiece 4 through the preset holes 901 on the drilling fixture 9, ensuring that the drilled hole is consistent with the position of the preset holes 901 on the drilling fixture 9, thereby ensuring the drilling accuracy. The height of the bench drill support frame 11 is adjustable. By adjusting the height of the bench drill support frame 11, the drill bit can maintain a suitable distance from the workpiece 4 to be machined with different thicknesses, ensuring the drilling depth and quality, and improving the adaptability of the tooling.

[0031] like Figure 4 As shown, workpiece 4 is a reinforcing rib for the upper sliding door, which is Z-shaped. Holes are drilled on the upper side. The specific operation process is as follows:

[0032] Workpiece 4 clamping: Place the workpiece 4 to be processed on the drilling fixture 9, so that the two ends of the upper side of the workpiece 4 are clamped at the right angle limiting edge 902. Use the quick clamp 10 to press the middle part of the workpiece 4 against the side of the support block 8 for limiting, so as to ensure that the workpiece 4 is firmly fixed on the drilling fixture 9.

[0033] Position adjustment: According to the position requirements of the drilling on the workpiece 4, the position of the clamping assembly is adjusted by the horizontal slider 5 and the vertical slider 7 so that the preset hole 901 on the drilling jig 9 is aligned with the drill bit on the bench drill 3.

[0034] Drilling operation: Select a drill bit that matches the preset hole 901 on the drilling fixture 9 and install it on the bench drill 3. Start the bench drill 3 and the drill bit will drill the workpiece 4 through the preset hole 901 on the drilling fixture 9. After drilling the same specification is completed, replace the drill bit with a drill bit of a different diameter to perform subsequent drilling until all drilling operations are completed. During the drilling process, pay attention to the drilling situation to ensure the drilling quality.

[0035] Machining Completion and Cleaning: After drilling is completed, turn off the bench drill 3, release the quick clamp 10, remove the machined workpiece 4, and clean the iron filings and debris from the surface of the tooling to prepare for the next machining.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
