Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a tooling for machining internal threads of machine tool jaws. Background Technology

[0002] In the field of general-purpose machine tools that employ workpiece rotation machining, chucks, as key functional components, have a large-scale machining demand. Due to the widespread application of such machine tools in industrial production, and the industry standard configuration of at least three chucks per unit, the production of chucks exhibits significant batch characteristics. This demand for large-scale production places stringent requirements on the efficiency and consistency of machining processes, which existing machining methods struggle to meet.

[0003] Existing chuck internal thread machining technologies have significant drawbacks: First, the method of welding two chucks together before machining requires secondary alignment of the internal thread hole before machining the sliding surface; second, the method of machining the entire component using a faceplate tooling followed by milling requires the blank to be prefabricated as a single piece. These methods are not only inefficient but also rely on manual alignment, leading to inconsistent precision and poor part uniformity, making them completely unsuitable for mass production. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a tooling for machining internal threads of machine tool chucks.

[0005] An embodiment of this utility model provides a tooling for machining internal threads in machine tool chucks, comprising:

[0006] A clamping component has a rectangular through hole inside, a claw body inside the clamping component, a notch on one side of the rectangular through hole, a side plate inside the notch, a first threaded rod through and threadedly connected to the top and one side of the clamping component, a plurality of adjusting pads inside the clamping component, a second threaded rod rotatably connected to the outer side of the adjusting pads, the second threaded rod passing through the clamping component and threadedly connected to it.

[0007] Furthermore, a T-shaped groove is provided through one side of the adjusting pad, and an I-shaped block is slidably disposed in the T-shaped groove.

[0008] Furthermore, the side plate has a through mounting hole, and the notch has a threaded opening, and the side plate is installed in the notch by screws.

[0009] Furthermore, a pressure plate is fixedly provided at the inner end of each of the first threaded rods.

[0010] Furthermore, rubber strips are fixedly provided at the bottom ends of both sides of the I-shaped block, and the rubber strips are tightly abutted against the inner side of the T-slot.

[0011] Furthermore, a rotating rod is fixedly provided at the outer end of both the first threaded rod and the second threaded rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. A clamping component is provided. The chuck body is placed inside the clamping component and limited. Then, the first threaded rod is tightened inward. The chuck body is pressed against the pressure plate, and the internal thread of the chuck body can be processed. The operation is simple and convenient, and the work efficiency is improved.

[0014] 2. An I-shaped block and a second threaded rod are incorporated. The second threaded rod moves the I-shaped block to accommodate jaw bodies of varying thicknesses; moving the I-shaped block along the corresponding T-slot allows for the adaptation to jaw bodies of different widths. This adaptability greatly enhances the equipment's versatility, enabling it to accommodate jaw bodies of varying thicknesses and widths.

[0015] In summary, this utility model enables convenient and efficient fixing of the chuck body, improving work efficiency; it can also flexibly adapt to the fixing needs of chuck bodies of different specifications, greatly enhancing the adaptability of the equipment. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a tooling for machining internal threads of machine tool chucks, comprising:

[0022] Clamping component 1 is installed at the center of the end face of the chuck of the machine tool lathe. A rectangular through hole is provided inside clamping component 1, and a jaw body 8 is installed inside clamping component 1 to fix the jaw body 8. A notch 3 is provided on one side of the rectangular through hole, and a side plate 2 is installed inside the notch 3. A mounting hole is provided on the side plate 2, and a threaded opening is provided inside the notch 3 for threaded connection with a screw. The side plate 2 is installed inside the notch 3 by a screw, which is used to fix the side plate 2 in place.

[0023] The top and one side of the clamping member 1 are both threaded with a first threaded rod 4, and the inner end of the first threaded rod 4 is fixedly provided with a pressure plate 5. The pressure plate 5 is used to clamp and fix the claw body 8.

[0024] The clamping component 1 has multiple adjusting pads 6 inside. A second threaded rod 7 is rotatably connected to the outer side of the adjusting pad 6, and the second threaded rod 7 passes through the clamping component 1 and is threadedly connected to it. The second threaded rod 7 can drive the adjusting pads 6 to move, thereby adapting to different sizes of jaw bodies 8.

[0025] The outer ends of the first threaded rod 4 and the second threaded rod 7 are both fixedly equipped with rotating rods 12, which make it easier for workers to rotate the first threaded rod 4 and the second threaded rod 7.

[0026] A T-slot 9 is provided through one side of the adjusting pad 6. An I-shaped block 10 is slidably disposed within the T-slot 9. The I-shaped block 10 is used to limit the position of the claw body 8. The I-shaped block 10 can slide within the T-slot 9, thereby accommodating claw bodies 8 of more specifications. Rubber strips 11 are fixedly disposed on both bottom ends of the I-shaped block 10. The rubber strips 11 are tightly abutted against the inner side of the T-slot 9. The rubber strips 11 are used to increase the friction between the I-shaped block 10 and the T-slot 9, ensuring that the I-shaped block 10 will not slide on its own.

[0027] The detailed working process of this utility model is as follows:

[0028] 1. During adjustment, multiple second threaded rods 7 drive the corresponding adjusting pads 6 and I-shaped blocks 10 to move, which can adapt to different thicknesses of the chuck body 8; by moving multiple I-shaped blocks 10 along the corresponding T-slots 9 in sequence, it can adapt to different widths of the chuck body 8.

[0029] 2. In use, place the two jaw bodies 8 inside the clamping part 1, and limit the two jaw bodies 8 by multiple I-shaped blocks 10. Finally, tighten the two first threaded rods 4 inward in sequence, and fix the two jaw bodies 8 by the corresponding pressure plates 5, so that the internal threads of the jaw bodies 8 can be processed. After processing, loosen the two first threaded rods 4 to release the jaw bodies 8, and then the jaw bodies 8 can be removed.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
