[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0015] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0016] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a heat treatment fixture for an integral subframe.

[0017] Combination Figures 1-3 As shown, the present invention provides an integral subframe heat treatment fixture, comprising: a fixture frame 100 and a fixing component 200 disposed on the fixture frame 100.

[0018] The fixing component 200 includes a support mechanism installed on the lower part of the tooling frame 100, a positioning mechanism disposed on the support mechanism, and a clamping mechanism installed on the upper part of the tooling frame 100. The support mechanism includes a telescopic rod 210 and a support rod 220 respectively hinged to the lower and middle parts of the tooling frame 100, a connecting rod 230 snapped onto the end of the telescopic rod 210, a positioning rod 240 connected to the end of the connecting rod 230, and an opening 250 formed on the support rod 220. The positioning mechanism includes a positioning seat 260 placed on the support rod 220, a positioning hole 270 formed on the positioning seat 260, a positioning block 280 inserted into the positioning hole 270, and an insert rod 290 fixed to the end of the positioning rod 240 and inserted into the positioning seat 260.

[0019] The telescopic rod 210 is one of the commonly used telescopic tubes, such as threaded telescopic rod, self-locking tension telescopic tube, or press-lock telescopic tube.

[0020] Specifically, the clamping mechanism includes a clamping rod 310 hinged to the upper part of the tooling frame 100, a guide groove 320 opened in the clamping rod 310, and a limiting block 330 clamped in the guide groove 320. Through the fixing assembly 200, the positioning rod 240 on the adjusted telescopic rod 210 can be inserted into the opening 250 on the support rod 220 to adjust the tilt angle of the support rod 220. Then, the positioning seat 260 is placed on the support rod 220, and the positioning block 280 is placed on the positioning seat 260 according to the structure of the subframe to limit the subframe. Then, the clamping rod 310 is released, and the limiting block 330 is pressed onto the subframe by the action of the spring 350 to complete the fixation. This solution can not only adapt to the fixation of subframes of different sizes and specifications, but also is simple and convenient to operate, saving time and effort.

[0021] Furthermore, the clamping rod 310 and the tooling frame 100 are respectively provided with fixing rings 340, and springs 350 are connected between the fixing rings 340. In the aforementioned solution, the self-weight of the clamping rod 310 can be used to clamp the subframe. In this solution, the springs 350 actively apply traction force to make the clamping rod 310 press more stably on the subframe, which is more practical.

[0022] Furthermore, the limiting block 330 has a pressure groove 360 ​​inside, which can further improve the stability of the limiting.

[0023] On the other hand, the end of the telescopic rod 210 is provided with a slot 231 for the connecting rod 230 to be engaged, and the opening of the slot 231 is in the shape of a trumpet, which allows the positioning rod 240 to rotate freely and thus be inserted into different positions on the support rod 220 as needed.

[0024] Furthermore, the tooling frame 100 is a triangular frame assembly made of perforated steel pipes. The perforated design can prevent water used in the heat treatment process from flowing out smoothly, making it highly practical.

[0025] The working principle and usage process of this utility model are as follows: First, the positioning rod 240 on the adjusted telescopic rod 210 is inserted into the opening 250 on the support rod 220 to adjust the tilt angle of the support rod 220. Then, the positioning seat 260 is placed on the support rod 220. Next, according to the structure of the subframe, the positioning block 280 is placed on the positioning seat 260 to limit the subframe. Then, the clamping rod 310 is released, and under the action of the spring 350, the limiting block 330 is pressed onto the subframe to complete the fixation. This allows for the adaptive fixation of subframes of different sizes and specifications.

[0026] The terms "fixed," "installed," "connected," "set up," "open," "equipped with," "embedded," and "assembled" used in this manual to describe the position or relationship of components all refer to conventional physical connections or spatial configurations that can be understood and implemented by those skilled in the art based on the function of the relevant components, the context, and common knowledge. These relationships encompass, but are not limited to, specific forms such as welding, bonding, threaded fastening, snap-fit, interference fit, plug-in, sliding fit, hinge, integral molding, adjacent arrangement, and opening or slot accommodating. Their purpose is to clearly describe the relative positions, mating methods, and functional implementation paths between components, rather than limiting a single specific structural detail. To ensure a smooth and concise reading experience and ease of understanding, no separate explanation is provided after each term.

[0027] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
