Description

Technical Field

[0001] The utility model relates to the technical field of correction devices, in particular to a correction device that prevents frame-type aluminum alloy castings from being deformed during heat treatment. Background Art

[0002] With the deepening of the design concepts of integration, integration, lightweight and precision in the field of aerospace, some frame-type aluminum alloy castings with large size, complex shape and structure, thin wall and high performance requirements are becoming more and more widely used. However, due to the complex structure and uneven wall thickness of such castings, large-scale shape deformation and partial complex deformation are prone to occur during heat treatment, which brings difficulties to the subsequent correction and use of the castings. Therefore, it is necessary to perform certain fixation and correction during the heat treatment of the castings to prevent deformation of the castings.

[0003] like Figure 1 As shown, in the prior art, three adjustable fixtures are installed outside the casting. During installation, positioning bolts 301 are used to constrain the casting 3 in the width direction, and the tightening force of the bolts inside and outside the casting 3 is maintained consistent;

[0004] However, the installation method using positioning bolts increases the difficulty of installation and wastes a lot of time. Therefore, it is necessary to propose a correction device for preventing heat treatment deformation of frame-type aluminum alloy castings to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a correction device to prevent deformation of frame-type aluminum alloy castings during heat treatment, which has the characteristics of conveniently driving two constraint plate bodies to constrain the width direction of the casting body at the same time, thereby improving the efficiency of installing three adjustable tooling on the outer wall of the casting body.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a correction device for preventing frame-type aluminum alloy castings from being deformed during heat treatment, comprising a casting body, the outer side wall of the casting body being installed with three evenly distributed and structurally identical adjustable toolings, the adjustable tooling comprising an upper pressure plate and an outer shell distributed up and down, a handle being provided on the left side of the outer shell, a bidirectional lead screw being installed on the right side of the handle, the right end of the bidirectional lead screw passing through the outer shell and being movably connected to the inner right side of the outer shell through a bearing, two threaded sleeves being movably connected to the outer side wall of the bidirectional lead screw, the upper end surfaces of the two threaded sleeves being installed with constraint plate bodies, the upper ends of the two constraint plate bodies respectively passing through and extending to the upper end of the outer shell.

[0007] In order to facilitate the replacement of the corresponding constraint plate according to the shape of the outer wall of the casting body, as a correction device for preventing heat treatment deformation of frame-type aluminum alloy castings in the utility model, the constraint plate body is preferably composed of a constraint plate, the lower end face of the constraint plate is provided with a plug-in groove, the interior of the plug-in groove is provided with a plug-in column which is detachably connected to the upper end face of the threaded sleeve, and a connecting bolt is penetrated and connected to the left side of the constraint plate and the plug-in column.

[0008] In order to facilitate the limiting effect on the movement of the two threaded sleeves, as a preferred correction device for preventing heat treatment deformation of frame-type aluminum alloy castings of the utility model, two sliding grooves are provided at the inner bottom end of the shell, and the interiors of the two sliding grooves are slidably connected with sliders that are detachably connected to the lower end surface of the threaded sleeve.

[0009] In order to facilitate the connection between the upper pressure plate and the outer shell, as a correction device for preventing frame-type aluminum alloy castings from being deformed during heat treatment, the utility model preferably has fixed plates welded on both sides of the left and right sides of the outer shell, and the two fixed plates are connected to the upper end surface of the upper pressure plate by two fastening bolts.

[0010] In order to prevent the hand from slipping on the handle, as a preferred correction device for preventing heat treatment deformation of frame-type aluminum alloy castings of the present invention, the outer side wall of the handle is fixedly connected with anti-slip grooves.

[0011] In order to facilitate the movement of the constraint plate body through the shell, as a preferred correction device for preventing heat treatment deformation of frame-type aluminum alloy castings of the utility model, the upper end surface of the shell is penetrated by two openings matching the constraint plate body.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] When the utility model installs three adjustable toolings for calibration on the outer wall of the casting body, the casting body is placed on the upper end of the shell and located between the two constraint plate bodies. Then the handle is held and rotated, and the handle drives the bidirectional lead screw to rotate. The two threaded sleeves move to the opposite side, driving the two constraint plate bodies to approach the outer wall of the casting body and fit with the outer wall of the casting body to constrain the casting body in the width direction. Then the device conveniently drives the two constraint plate bodies to constrain the casting body in the width direction at the same time, thereby improving the efficiency of installing the three adjustable toolings on the outer wall of the casting body.
