Abstract
Description
Technical Field
[0001] This utility model relates to the field of tempering tooling technology, and in particular to a tempering tooling for a transmission frame. Background Technology
[0002] Currently, after the transmission frame has been welded, it needs to be tempered to improve its overall strength. Some existing traditional operating methods place the workpiece on a fixture and fix it with a single lead screw and clamping block for tempering.
[0003] Traditional tempering fixtures are not only cumbersome to operate in practical applications, but also easily cause the workpiece processing quality and efficiency to fail to meet production requirements. Therefore, there is an urgent need for a transmission frame tempering fixture. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tempering fixture for a transmission frame.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A tempering fixture for a transmission frame includes a base plate. The upper part of the base plate is provided with a plurality of positioning posts to limit the workpiece being processed. The middle part of the positioning posts is provided with a support plate to support the workpiece. A telescopic post is installed in the middle part of the positioning posts through a spring member. Limiting plates are rotatably installed on both sides of the outer wall of the telescopic post. After the limiting plates are rotated and unfolded, they press and contact the upper wall of the workpiece.
[0007] In addition, a preferred structure is that an annular groove is formed on the bottom side of the middle part of the positioning post, and a pair of limiting grooves are symmetrically formed on the outer side of the inner wall of the annular groove, with the other end of the limiting groove horizontally penetrating the outer wall of the positioning post.
[0008] In addition, a preferred structure is that a spring is fitted inside the annular groove, one end of the spring is connected to the support plate, and a protrusion is provided on the inner side of the support plate to limit its sliding installation in the limiting groove.
[0009] In addition, a preferred structure is that the positioning post has a mounting hole in the middle, a telescopic post is slidably installed in the mounting hole, and the telescopic post is connected to the mounting hole by a spring.
[0010] In addition, a preferred structure is that the outer wall of the telescopic column is provided with slots on both sides, and a limit plate is rotatably installed on one side of the slot via a pin. A torsion spring is provided at the rotatable connection between the limit plate and the slot, and the torsion spring generates a torsional force that always faces downward.
[0011] Furthermore, in a preferred configuration, under the influence of the torsional force of the torsion spring, the limiting plate is parallel and attached to the telescopic column in its natural state, and the bottom end of the limiting plate is pressed against the top wall of the positioning column.
[0012] The beneficial effects of this utility model are as follows:
[0013] In this invention, the positioning column can effectively limit the workpiece being processed and provide effective support for its various connection nodes, thereby improving its stability during the tempering process. At the same time, during the assembly process, the workpiece can be limited simply by pulling the telescopic column and unfolding the corresponding limiting plates on both sides. Its operation is convenient and effectively improves processing efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-6A tempering fixture for a transmission frame includes a base plate 1. Multiple positioning posts 2 are provided on the upper part of the base plate 1 to limit the workpiece 5 to be processed. A support plate 4 is provided in the middle of the positioning posts 2 to support the workpiece. A telescopic post 3 is installed in the middle of the positioning posts 2 through a spring member 8. Limiting plates 6 are rotatably installed on both sides of the outer wall of the telescopic post 3. After the limiting plates 6 are rotated and unfolded, they press and contact the upper wall of the workpiece.
[0023] Furthermore, an annular groove 211 is provided on the bottom side of the middle part of the positioning post 2, and a pair of limiting grooves 21 are symmetrically provided on the outer side of the inner wall of the annular groove 211. The other end of the limiting groove 21 horizontally penetrates the outer wall of the positioning post 2.
[0024] Furthermore, a spring component 7 is fitted inside the annular groove 211. One end of the spring component 7 is connected to the support plate 4. A protrusion is provided on the inner side of the support plate 4 to limit its sliding installation in the limiting groove 21, thereby ensuring the stability of the movement of the support plate 4.
[0025] Furthermore, a mounting hole 22 is provided in the middle of the positioning column 2, and a telescopic column 3 is slidably installed in the mounting hole 22. The telescopic column 3 is connected to the mounting hole 22 by a spring member 8.
[0026] Furthermore, slots are provided on both sides of the outer wall of the telescopic column 3. A limiting plate 6 is rotatably installed on one side of the slot via a pin. A torsion spring 61 is provided at the rotatable connection between the limiting plate 6 and the slot. The torsion spring 61 generates a torsional force that always faces downward. The limiting plate 6 limits the upper wall of the workpiece to ensure its installation stability.
[0027] Furthermore, in its natural state, under the influence of the torsional force of the torsion spring 61, the limiting plate 6 is parallel and attached to the telescopic column 3, and the bottom end of the limiting plate 6 is pressed and contacted with the top wall of the positioning column 2.
[0028] In this embodiment, multiple positioning posts 2 on the base plate 1 limit the workpiece 5 to be processed, i.e., the transmission frame. The positioning posts 2 can support each connection node of the workpiece, thereby ensuring its stability during the processing.
[0029] In practical applications, one or more workpieces 5 to be processed are assembled onto the positioning column 2, and the telescopic column 3 in the middle of the positioning column 2 is pulled. At the same time, the limiting plates 6 on both sides are rotated and unfolded. After unfolding, the limiting plates 6 are in a horizontal "I" shape. Under the reset action of the spring component 8, the limiting plates 6 contact the upper surface of the workpiece and limit it, ensuring the stability of the processing.
[0030] After processing is completed, simply pull the telescopic column 3 upwards again. At this time, under the action of the torsion spring 61, the limit plate 6 will automatically reset, and the workpiece can be directly removed from the positioning column 2.
[0031] In practical applications, the spring component 7 supports the pallet 4. After the workpiece is assembled, the pallet 4 supports the workpiece and, together with the limiting plate 6, limits its movement.
[0032] In practical applications, the force generated by the tension of the spring component 8 causes the limiting plate 6 to press stably onto the workpiece.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
