Description

Technical Field

[0001] The utility model relates to the technical field of worm processing, in particular to a milling sleeve which is convenient for disassembling and assembling a worm. Background Art

[0002] With the development of modern manufacturing industry, worm is a key transmission element, and its processing accuracy and efficiency are crucial to the overall equipment performance. Traditional milling sleeve design often faces many challenges, especially in adapting to the positioning operation of worms of different sizes (length and thickness); worm refers to a gear with one or more spiral teeth, which meshes with the worm wheel to form a staggered axis gear pair. Its dividing surface can be a cylindrical surface, a conical surface or a torus surface. There are four types of Archimedean worm, involute worm, normal straight worm, and conical envelope cylindrical worm. The working principle of the worm is based on the principle of meshing gears, but unlike ordinary gears, the spiral shape of the worm makes it self-locking, which means that the rotation of the worm will prevent the worm wheel from reversing, thereby achieving a certain degree of anti-reversal effect. In addition, since the worm wheel teeth have high bending strength, they can withstand large loads, but the surface strength of the worm wheel is relatively low, so the bending strength and surface strength of the worm transmission are quite different.

[0003] Traditional milling sleeves usually have fixed structures and sizes, which makes it difficult to achieve accurate positioning and fixation when facing worms of different specifications. Differences in the length and thickness of the worms may lead to inaccurate positioning, which in turn affects the processing accuracy. In addition, since the disassembly and assembly process of traditional milling sleeves is complicated and time-consuming, operators need to spend a lot of time and energy to replace and adjust the milling sleeves to adapt to worms of different sizes, which not only reduces production efficiency but also increases operating costs.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-3As shown in the figure, a milling sleeve facilitating the disassembly and assembly of a worm includes a bearing housing 1. Slide grooves 2 are respectively formed on the two side walls of the bearing housing 1. Two connecting plates 3 are respectively slidably connected to the interiors of the two slide grooves 2. The tops of the two connecting plates 3 are fixedly connected with a U-shaped plate 4. Milling sleeve bodies 5 are respectively fixedly connected to the opposite side walls of the two U-shaped plates 4. Two positioning assemblies 6 for clamping a worm to be processed are respectively arranged in the inner cavities of the two milling sleeve bodies 5. A driving assembly 7 for adjusting the distance between the two milling sleeve bodies 5 is arranged inside the bearing housing 1. The U-shaped plate 4 is arranged on the moving end of the driving assembly 7.

[0021] The utility model can flexibly adjust the distance between the two milling sleeve bodies 5, so as to be applicable to worms of different length specifications, which is beneficial to improving the use flexibility of the milling sleeve body 5. In addition, worms of different thickness specifications can be clamped and positioned, thereby further improving the use flexibility of the milling sleeve body 5.

[0022] Further, the positioning assembly 6 includes a threaded column 601. The outer wall of the threaded column 601 is threadedly connected to the side wall of the milling sleeve body 5. One end of the threaded column 601 is rotatably connected to a clamping plate 602 in the milling sleeve body 5. A V-shaped groove 603 is formed on one side wall of the clamping plate 602. With the above design, since the opening of the V-shaped groove 603 gradually narrows, it can accommodate worms of different diameters within a certain range and stably support the worm through the groove walls on both sides, and can well adapt to worms of different thicknesses.

[0023] Further, an adjusting knob 8 is further included. The adjusting knob 8 is fixedly connected to the end of the threaded column 601 away from the clamping plate 602. With the above design, by rotating the adjusting knob 8, the threaded column 601 can be driven to rotate, so as to drive the clamping plate 602 to advance, and further clamp the outer wall of the worm to be processed and position the worm.

[0024] Further, two guide rods 9 are further included. One ends of the two guide rods 9 are fixedly connected to one side wall of the clamping plate 602. The other ends of the two guide rods 9 penetrate through the milling sleeve body 5, and the two guide rods 9 are slidably connected to the milling sleeve body 5. With the above design, by arranging the guide rods 9, it plays a role in limiting the clamping plate 602, making the movement of the clamping plate 602 more stable and capable of providing a stable clamping force for the worm.

[0025] Further, the driving assembly 7 includes a bidirectional lead screw 701. The two ends of the bidirectional lead screw 701 are respectively rotatably installed on the inner walls of both sides of the bearing housing 1. One end of the bidirectional lead screw 701 penetrates through the bearing housing 1 and is connected to a driving motor 702. Two groups of driving blocks 703 are symmetrically threadedly connected to the outer wall of the bidirectional lead screw 701. The connecting plate 3 is fixedly installed on the top of the driving blocks 703. With the above design, the output shaft of the driving motor 702 drives the bidirectional lead screw 701 to rotate forward and backward, so as to drive the two groups of driving blocks 703 to reciprocate along the axial direction of the bidirectional lead screw 701. Furthermore, the two groups of C-shaped plates 4 can be driven by the connecting plate 3 to move synchronously with the two groups of driving blocks 703, thereby achieving the effect of adjusting the distance between the two milling sleeve bodies 5; thus, it can be applicable to worms of different lengths.

[0026] Further, the driving motor 702 is fixedly installed on one side wall of the bearing housing 1. One end of the output shaft of the driving motor 702 is fixedly connected to one end of the bidirectional lead screw 701. The driving motor 702 is set as a forward and reverse stepping motor. An installation plate 10 is fixedly installed at the bottom of the bearing housing 1. A plurality of groups of positioning through holes 11 are opened on the top of the installation plate 10. The plurality of groups of positioning through holes 11 are arranged in pairs symmetrically. By providing the installation plate 10 and the positioning through holes 11, the whole device can be installed on a processing milling machine.

[0027] In summary, the utility model can conveniently achieve the rapid positioning, fixing and disassembly of the worm, ensure the stability and accuracy of the worm during the processing. At the same time, the design of the milling sleeve body 5 also improves the convenience and safety of the operation, enabling the operator to easily master the disassembly and assembly method and avoid accidents during the disassembly and assembly process.

[0028] Working principle: When the utility model is used, the output shaft of the driving motor 702 drives the bidirectional lead screw 701 to rotate forward and backward, so as to drive the two groups of driving blocks 703 to reciprocate along the axial direction of the bidirectional lead screw 701. Furthermore, the two groups of C-shaped plates 4 can be driven by the connecting plate 3 to move synchronously with the two groups of driving blocks 703, thereby achieving the effect of adjusting the distance between the two milling sleeve bodies 5. Subsequently, according to the length of the worm to be processed, the two milling sleeve bodies 5 are adjusted to appropriate positions. The two ends of the worm are respectively inserted into the inner cavities of the milling sleeve bodies 5. By rotating the adjusting knob 8, the threaded column 601 can be driven to rotate, so as to drive the clamping plate 602 to advance, and further clamp the outer wall of the worm to be processed and position it to avoid the worm shifting during the processing.
