Description

Technical Field

[0001] This utility model belongs to the field of oil hole fixture technology, and particularly relates to an oil hole fixture adapted to worm gear tooth groove and internal trapezoidal thread tooth groove. Background Technology

[0002] In the field of machining, worm gears and workpieces with internal trapezoidal threads play a crucial role in many industrial applications. However, machining these workpieces, especially in the process of creating oil holes, often presents several technical challenges.

[0003] On the one hand, worm gear tooth grooves have specific shape and size requirements, and their complex curved surface structure makes it difficult for traditional fixtures to achieve precise positioning and fixation. When machining oil holes, if the fixture cannot be well adapted to the worm gear tooth grooves, it can easily lead to reduced machining accuracy, inaccurate oil hole positions, and affect the working performance and service life of the worm gear.

[0004] On the other hand, the internal trapezoidal thread groove also has unique geometric characteristics. Due to the special shape of its thread, ordinary clamps are difficult to penetrate deep into the thread for stable clamping, which poses a great challenge to the fabrication of oil holes. If the workpiece cannot be effectively fixed, problems such as shaking and displacement may occur during processing, thus affecting the quality and accuracy of the oil hole. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing equipment struggles to achieve precise positioning and fixation.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an oil-making hole fixture adapted to worm gear tooth grooves and internal trapezoidal thread tooth grooves, including a base and an adjustment component disposed on the upper end of the base, the adjustment component being used to adapt to worm gears and internal trapezoidal thread tooth groove workpieces of different sizes; and further including a clamping component disposed between the adjustment components, the clamping component being used to prevent the workpiece from loosening during processing.

[0007] Furthermore, the adjustment assembly includes a slider, a double helix screw, a bracket, and a clamping block. The upper end of the base has a groove. The slider is symmetrically slidably disposed inside the groove. The double helix screw is rotatably disposed inside the groove. Both ends of the double helix screw pass through the base, and one end of the double helix screw passes through the base. The bracket is fixed to the upper end of the slider. The slider is threadedly connected to the double helix screw. The clamping block is fixed to the inner side of the bracket and has toothed grooves.

[0008] Furthermore, the clamping assembly includes a second slider, a second double helical screw, and a second bracket. A second sliding groove is provided on the inner side of the clamping block. The second slider is symmetrically slidably disposed inside the second sliding groove. The second double helical screw is rotatably disposed inside the second sliding groove. Both ends of the second double helical screw pass through the second bracket, and one end of the second double helical screw passes through the second bracket. The second slider is threadedly connected to the second double helical screw. A gasket is adhered to the opposite side of the second bracket.

[0009] Furthermore, the first slide groove is trapezoidal, the first slider is trapezoidal, and the first slider is matched with the first slide groove.

[0010] Furthermore, the second slide groove is trapezoidal, the second slider is trapezoidal, and the second slider is matched with the second slide groove.

[0011] Furthermore, the first bracket is arc-shaped and symmetrical about the central axis of the base.

[0013] Furthermore, the aforementioned components are made of high-strength alloy steel, possessing sufficient rigidity and stability.

[0014] The beneficial effects of this utility model after adopting the above structure are as follows:

[0015] (1) By adjusting the matching settings of slider one, double helical screw one, bracket one and clamping block in the assembly, an adjustable clamping force adjustment device can be realized to adapt to workpieces of different sizes and to ensure that the workpiece is accurately positioned in the fixture.

[0025] like Figure 1 As shown, the oil-making hole fixture that adapts to the worm gear tooth groove 8 and the internal trapezoidal thread tooth groove 8 includes a base 1 and an adjustment component 2 disposed on the upper end of the base 1. The adjustment component 2 is used to adapt to worm gears and internal trapezoidal thread tooth groove 8 workpieces of different sizes. It also includes a clamping component 3 disposed between the adjustment components 2. The clamping component 3 is used to prevent the workpiece from loosening during the processing.

[0026] The base is designed to be fixed to the machine tool workbench for easy installation and disassembly.

[0027] like Figure 2-4 As shown in Figure 6, the adjustment assembly 2 includes a slider 4, a double helical screw 5, a bracket 6, and a clamping block 7. A groove is provided at the upper end of the base 1. The slider is symmetrically slidably disposed inside the groove. The groove is trapezoidal, and the slider 4 is trapezoidal and fits the groove. The double helical screw is rotatably disposed inside the groove. Both ends of the double helical screw 5 pass through the base 1, and one end of the double helical screw 5 passes through the base 1. The bracket 6 is fixed to the upper end of the slider. The bracket 6 is arc-shaped and symmetrical about the central axis of the base 1. The slider 4 is threadedly connected to the double helical screw 5. The clamping block 7 is fixed to the inner side of the bracket 6 and has a toothed groove 8.

[0028] The double helical screw 5 is rotated by rotating it through one end of the base 1, and the slider 4 moves in opposite directions to realize the adjustable clamping force adjustment device so as to adapt to workpieces of different sizes. The shape of the tooth groove 8 on the precise clamping block 7 matches the tooth groove 8 of the worm gear, which can tightly clamp the worm gear and ensure that the workpiece is accurately positioned in the fixture.

[0029] like Figure 2-3As shown in Figure 5, the clamping assembly 3 includes a second slider 9, a second double helical screw 10, and a second bracket 11. A second groove is provided on the inner side of the clamping block 7. The second slider 9 is symmetrically slidably disposed inside the second groove. The second groove is trapezoidal, and the second slider 9 is trapezoidal, and the second slider 9 is matched with the second groove. The second double helical screw 10 is rotatably disposed inside the second groove. Both ends of the second double helical screw 10 pass through the second bracket 11. The second bracket 11 is arc-shaped and symmetrical about the central axis of the clamping block 7. One end of the second double helical screw 10 passes through the second bracket 11. The second slider 9 is threadedly connected to the second double helical screw 10. A gasket 12 is bonded to the opposite side of the second bracket 11.

[0030] The aforementioned components are made of high-strength alloy steel. By rotating the part of the double helical screw 10 that passes through the bracket 11, the double helical screw 10 is driven to rotate, which in turn drives the slider 9 to move in opposite directions. Under the clamping action of the bracket 11, sufficient clamping force is provided to prevent the workpiece from loosening during processing.
