Embodiment 1

[0016] Example 1, such as figure 1 with figure 2 , Which relates to a heat treatment mold device, including a slider 4, a cylindrical base 1, ten screws 2, a nut 3; on the circumferential side wall of the base 1, ten non-through holes are opened and evenly distributed, and ten screws 2 are respectively inserted into ten blind holes and connected by radial welding; at the outer end of each screw 2, two nuts 3, slider 4, and nut 3 are connected in sequence from the inside to the outside; the slider 4 is arranged through the front and back The nut 3 is fixed; the slider 4 is composed of a fixed plate 41 with a central hole and an arc support plate 42 welded on both sides of the fixed plate. The slider 4 acts on the outer edge of the arc of the arc support plate 42 To support the inner wall of the ring gear. In use, by adjusting the front and rear nuts 3, the outer edges of the sliders 4 on the screw 2 are on the same circumferential surface, and the radius R of the circumferentia...

Embodiment 2

[0017] Example 2, such as image 3 As shown, on the basis of the embodiment, the screw 2 is divided into two sections, a front rod 2-1 and a rear rod 2-2. The front rod 2-1 and the rear rod 2-2 are inserted into each other, and the two-section screw A plurality of radial through holes are successively opened along the axial direction of the overlapping part of the, and a positioning pin 5 is provided, which respectively passes through the through holes on the two screw rods to achieve positioning and fixed connection.

Abstract

The invention relates to a clamping fixture device used for the heat treatment of a gear ring. The device comprises sliding blocks, a base, screw stems and nuts; the base is in a cylinder structure and is provided with at least three screw stems which are evenly welded on the peripheral side wall of the base along the radial direction; each screw stem is provided with at least two nuts, and the sliding block is sheathed on the screw stem and is clamped between the nuts through a center hole of the sliding block; and the outer edges of all the sliding blocks are on the same circle by adjustingthe front nut and the back nut. The structure of the clamping fixture device is simple, the design is skillful, the fine adjustment and substantial adjustment of the supported radius of the device are realized only by combination of the screw stems and the nuts, the close fitting of the sliding block and the inner wall of the gear ring is ensured, meanwhile, the unity of all the sliding blocks isprecisely ensured by fine adjustment, and the precision of the gear ring is ensured; moreover, a plurality of supporting sliding blocks can be arranged according to requirements, support points are added, the deformation of the gear ring is further reduced, a solid foundation for subsequent processes is built, and the labor intensity of subsequent processes is reduced.

Description

Technical field [0001] The invention relates to a mold device, in particular to a mold device used in the heat treatment process of a ring gear. Background technique [0002] Heat treatment is a metal thermal processing technology in which metal materials are heated, insulated and cooled in a certain medium, and their performance is controlled by changing the surface or internal metallographic structure of the material. Metal heat treatment is one of the important processes in mechanical manufacturing. [0003] Gears and ring gears are the basic workpieces in mechanical transmission, and their quality, performance, and life span directly affect the performance indicators and operating conditions of the whole machine. The processing of gears and ring gears is also a complex technical process involving cold and hot processing. It needs to be processed in the process of repeated heating and cooling. Because gears and ring gears are made of steel and other materials, they follow therm...
