[0017] 2. In this utility model, after the bevel gear body is placed on the annular electromagnet, the telescopic cylinder is activated, causing the first connecting block to drive the second connecting block toward the bevel gear body. Then, the clamping block will use the arc-shaped rubber pad to fix the shaft surface of the bevel gear body. At the same time, the support block above the clamping block will also drive the clamping teeth to fix the bevel teeth of the bevel gear body. By fixing at two positions, the clamping and fixing effect of the bevel gear body can be effectively improved.

[0018] 3. In the present invention, the clamping block and the supporting block can be replaced according to the bevel gear bodies of different sizes, which is convenient for fixing and clamping bevel gear bodies of different sizes, and the replacement method is relatively simple and quick.

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] refer to Figure 1-2 A gear clamping chuck includes a chuck body 1. A plurality of ear plates 11 are fixedly provided in a ring shape on the outer side of the chuck body 1, and the chuck body 1 can be fixedly connected to a processing machine tool through the ear plates 11.

[0027] refer to Figure 2 An annular electromagnet 13 is fixedly installed at the center of the chuck body 1 to adsorb the shaft end of the bevel gear body 5, making it convenient for the subsequent clamping and fixing of the bevel gear body 5.

[0028] refer to Figure 1-2 A plurality of slide grooves 12 are provided in a ring shape on the surface of the chuck body 1, and a connecting block 21 is slidably installed in the slide groove 12. A telescopic cylinder 2 is fixedly installed at a position corresponding to the slide groove 12 on the outer side of the chuck body 1. The piston rod of the telescopic cylinder 2 is fixed to the connecting block 21, and the connecting block is driven to slide in the slide groove 12 by the telescopic cylinder 2.

[0029] refer to Figure 1-3 A connecting block 2 32 is installed in the connecting block 1 21 , and the connecting block 2 32 can be slidably engaged with the connecting block 1 21 , making it easy to replace the connecting block 2 32 .

[0030] refer to Figure 3A square through slot 211 is symmetrically provided on the side of the connecting block 1 21, and a fixing plate 6 corresponding to the through slot 211 is fixedly installed on the outside of the through slot 211 by bolts. The fixing plate 6 can be removed.

[0031] refer to Figure 3-5 A trapezoidal block 61 is provided on the right side of the fixed plate 6, and a spring 62 is fixedly connected between the trapezoidal block 61 and the fixed plate 6, and a sliding shaft 63 that passes through the fixed plate 6 is welded on the outer side surface of the trapezoidal block 61. The sliding shaft 63 is slidably matched with the fixed plate 6, and a pull ring 631 is fixedly provided at the outer end of the sliding shaft 63. By pulling the pull ring 631, the trapezoidal block 61 can slide in the through groove 211.

[0032] refer to Figure 3-5 A card slot 321 that matches the shape of the trapezoidal card block 61 is symmetrically opened on the outer side surface of the connecting block 2 32 , and the trapezoidal card block 61 can slide into the card slot 321 .

[0033] refer to Figure 1-2 The clamping block 3 slides on the surface of the chuck body 1, and an arc-shaped rubber pad 31 is fixedly provided in the arc-shaped groove on the outer side of the clamping block 3. The arc-shaped rubber pad 31 can prevent the surface of the shaft segment of the bevel gear body 5 from being damaged by excessive clamping force.

[0034] Specifically, the second connecting block 32 is slid into the groove of the first connecting block 21, and then the second connecting block 32 touches the trapezoidal card block 61, causing it to shrink into the through groove 211. When the second connecting block 32 falls into the groove, the trapezoidal card block 61 enters the card slot 321, completing the fixation of the second connecting block 32 and the first connecting block 21. When the second connecting block 32 needs to be replaced, pull the outer pull ring 631, and the trapezoidal card block 61 exits the card slot 321, and the second connecting block 32 can be pulled to separate it from the first connecting block 21.

[0035] refer to Figure 1-2 A support block 4 is provided on the upper surface of the connecting block 2 32, and the support block 4 is fixedly connected to the connecting block 2 32 by bolts. The upper end surface of the support block 4 is symmetrically fixed with clamping teeth 41 for clamping the bevel gear body 5, and the clamping teeth 41 can engage with the bevel gear.

[0036] Furthermore, after placing the bevel gear body 5 on the annular electromagnet 13, the telescopic cylinder 2 is started, so that the connecting block 1 21 drives the connecting block 2 32 close to the bevel gear body 5, and then the clamping block 3 will fix the shaft segment surface of the bevel gear body 5 through the arc-shaped rubber pad 31. At the same time, the supporting block 4 above the clamping block 3 will also drive the clamping teeth 41 to fix the bevel tooth position of the bevel gear body 5. By fixing the two positions, the clamping and fixing effect of the bevel gear body 5 can be effectively improved.

[0037] Furthermore, the clamping block 3 and the supporting block 4 can be replaced according to the bevel gear bodies 5 of different sizes, so as to facilitate the fixed clamping of bevel gear bodies 5 of different sizes, and the replacement method of this embodiment is relatively simple and quick.

[0038] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0039] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.
