Description

Technical Field

[0001] This utility model belongs to the field of machining technology, and specifically relates to a small-batch drilling fixture. Background Technology

[0002] In the field of machining, drilling and tapping of small workpieces (such as gaskets and connecting plates) widely employs bench vise clamping or lead screw clamping. These traditional clamping methods have the following significant drawbacks:

[0003] (1) Limited number of items that can be clamped at one time:

[0004] Limited by the opening size of the vise or the coverage of the clamping plate, batch clamping cannot be achieved, and frequent disassembly and replacement of workpieces are required, resulting in a high proportion of auxiliary time.

[0005] (2) Low efficiency in switching between drilling and tapping processes:

[0006] When a workpiece requires drilling before tapping threads, the operator must repeatedly change drill bits and taps. Each change takes a long time, and frequent tool changes increase the risk of tool wear.

[0007] (3) Poor adaptability:

[0008] Traditional fixtures are sensitive to changes in workpiece dimensions. Different specifications of workpieces require customized fixtures, which leads to extended changeover time on the production line and makes it difficult to meet the needs of multi-variety, small-batch production.

[0009] Therefore, existing technologies result in low efficiency in small-part processing and increased production costs, creating an urgent need for a specialized fixture that supports simultaneous clamping of multiple workpieces, adapts to size changes, and eliminates the need for tool switching. Summary of the Invention

[0010] The purpose of this utility model is to address the problems of existing small-part drilling fixtures, such as small number of parts clamped at one time, frequent switching of drilling and tapping processes, and poor size adaptability, and to provide a small-part batch drilling fixture.

[0019] A small slide block that is slidably connected to a vertical slide rail;

[0020] A vertical adjusting screw that drives the small slide to move vertically;

[0021] A positioning block is located at one end of the slide and the fixed seat;

[0022] The clamping device, located at the other end of the slide and the fixed seat, is used to clamp opposite sides of the workpiece in the thickness direction.

[0023] Furthermore, the axis of the horizontal adjusting screw is parallel to the horizontal slide rail, the middle part is threaded with the slide block, one end is rotatably connected to the base plate through a bearing, and the other end extends to the outside of the base plate and is provided with a first rotating handle.

[0024] Furthermore, the small slide block is threadedly engaged with the slide block or fixed seat via a vertical adjusting screw, and the rotation of the vertical adjusting screw drives the small slide block to move up and down along the vertical slide rail.

[0025] Furthermore, the axis of the vertical adjusting screw is parallel to the vertical slide rail, the middle part is threadedly engaged with the small slide block, the lower end is rotatably connected to the slide block or fixed seat through a bearing, and the upper end extends above the stop structure and is provided with a second rotating handle.

[0026] Furthermore, the positioning block is a detachable structure, which is fixed to the end of the slide and the fixed seat by bolts.

[0027] Furthermore, the tightening device is a screw tightening mechanism or a quick clamp, and its tightening direction is parallel to the axis of the horizontal adjusting screw.

[0028] Furthermore, the base plate is provided with mounting holes for fixing the fixture as a whole to the worktable of the processing equipment.

Detailed Implementation

[0035] The present invention will be further explained below with reference to the accompanying drawings.

[0036] like Figure 1-3 As shown, the small-part batch drilling fixture of this utility model includes a base plate 1, a horizontal adjustment system, a vertical clamping system, and a positioning and clamping unit. Wherein:

[0037] The base plate 1 is made of steel and is rectangular in shape. The base plate 1 has multiple mounting holes for fixing to the drilling machine worktable with bolts.

[0038] Horizontal adjustment system:

[0039] Two parallel horizontal slide rails 2 are symmetrically fixed to the upper surface of the base plate 1 by bolts;

[0040] The bottom of the slide block 3 is equipped with a slider that matches the horizontal slide rail 2, enabling horizontal sliding;

[0041] The horizontal adjusting screw 4 passes through the threaded hole in the middle of the slide block 3, and its axis is parallel to the horizontal slide rail 2. One end of the horizontal adjusting screw 4 is connected to the side wall of the base plate 1 through a bearing, and the other end extends out of the base plate 1 and is equipped with a first rotating handle 12. Rotating the handle can drive the slide block 3 to move horizontally.

[0042] Vertical clamping system:

[0043] A vertical slide rail 9 is installed on the upper surface of both the slide block 3 and the fixed base 5;

[0044] The small slide block 6 is connected to the vertical slide rail 9 via a slider;

[0045] The vertical adjustment screw 10 passes through the threaded hole of the small slide block 6, and its lower end is connected to the slide block 3 or the fixed seat 5 through a bearing. The vertical adjustment screw 10 is parallel to the vertical slide rail 9. The upper end of the vertical adjustment screw 10 extends to the stop structure 11 and a second rotating handle 13 is installed above it. The rotating handle drives the small slide block 6 to rise and fall vertically.

[0046] Positioning and clamping unit:

[0047] Stop structure 11: A boss is machined on the upper surface of the slide 3 and the fixed seat 5 to position the workpiece plate thickness direction;

[0048] Positioning block 7: It can be detachably installed on the front end of slide 3 and fixed seat 5 by bolts, and provides a reference in the length direction of the workpiece;

[0049] Tightening device 8: It adopts a screw-type screw tightening mechanism, which is installed at the rear end of the slide 3 and the fixed seat 5, and the tightening direction is parallel to the axis of the horizontal screw 4.

[0050] Workpiece clamping operation procedure:

[0051] (1) Rotate the first handle 12 to adjust the position of the slide block 3 so that the distance between the slide block 3 and the fixed seat 5 matches the workpiece width;

[0052] (2) Place multiple workpieces on the stop structure 11, with the long side of the workpiece close to the positioning block 7;

[0053] (3) Rotate the second handle 13 to drive the small slide block 6 to press down, so that the workpiece plate surface direction is fixed;

[0054] (4) Tighten the screw of the clamping device 8 to clamp the workpiece on opposite sides and complete the locking. Figure 3 .

[0055] This utility model achieves the core objectives of simultaneous clamping of multiple workpieces, integrated processing of drilling and tapping operations, and rapid changeover to adapt to workpieces of different sizes through the parallel layout of the slide and fixed base, the horizontal / vertical dual-dimensional adjustment mechanism, and the modular clamping unit.

[0056] The small-batch drilling fixture of this utility model can achieve the following technical effects:

[0057] (1) Increased clamping efficiency: Based on the parallel stop positioning structure 11 of slide 3 and fixed seat 5, workpieces can be clamped in batches in a single batch.

[0058] (2) Seamless process integration: The workpiece is locked in both directions by the positioning block 7 and the clamping device 8, ensuring zero displacement of the workpiece in the drilling and tapping process, completely eliminating the drill / taper switching link, and reducing the processing time of a single piece.

[0059] (3) Strong dimensional versatility: The horizontal adjusting screw 4 drives the slide 3 to move horizontally to adapt to the workpiece width, and the vertical adjusting screw 10 drives the small slide 6 to press vertically to adapt to the thickness. Combined with the detachable positioning block 7, the length direction can be adjusted to achieve full coverage of the three-dimensional dimensions of width, thickness and length.

[0060] (4) Convenient and efficient operation: The external first rotary handle 12 and second rotary handle 13 provide an intuitive operation interface;

[0061] (5) Overall cost optimization: Reduce the demand for customized special fixtures and tool changeover wear, thereby reducing the overall production cost of small-part batch processing and significantly enhancing the market competitiveness of products.

[0062] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
