[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3 , the utility model provides an embodiment: a jig double-speed chain transmission mechanism, including a workbench 1, a fixing frame 3 is installed on the left side of the top of the workbench 1, and an electric push rod 12 is fixedly connected to the left end of the fixing frame 3, the output end of the electric push rod 12 passes through the fixing frame 3 and is fixedly connected to a fixing ring 11, and an electric push rod 2 10 is fixedly connected to the inner side of the fixing ring 11, and the output end of the electric push rod 2 10 passes through the fixing frame 3, an industrial fan 8 is arranged at the bottom of the workbench 1, the input end of the industrial fan 8 is connected to an air intake pipe 13, and the output end of the industrial fan 8 is connected to an exhaust pipe 7, and a positioning mechanism 2 is arranged on the rear side of the fixing frame 3; the end of the air intake pipe 13 is connected to an air collecting plate 9; a conveyor belt assembly 4 is installed on the right side of the workbench 1;

[0030] Specifically, the workpiece needs to be accurately placed on the left side of the workbench 1 first; this step is crucial because it lays the foundation for subsequent automated operations; next, the industrial fan 8 is turned on to drive the air intake pipe 13 and the air collecting plate 9 to intake air; the role of this step is to increase the adsorption space range through the air collecting plate 9, so that the workpiece can be adsorbed more stably; then, the electric push rod 10 starts to work, driving the air intake pipe 13 and the air collecting plate 9 to move downward; in this process, the air collecting plate 9 adsorbs the workpiece to ensure that it does not fall off or shift; When the electric push rod 2 10 is retracted and lifted, the electric push rod 1 12 starts to drive the fixed ring 11 to move to the right; the purpose of this step is to accurately move the adsorbed workpiece to the position of the next process; at the same time, the conveyor belt assembly 4 also starts to operate, ready to receive the workpiece dropped from the fixed ring 11; when the air collecting plate 9 moves to the upper position of the conveyor belt assembly 4, the industrial fan 8 is turned off, so that the workpiece can naturally fall on the conveyor belt assembly 4 for transportation; this process not only realizes the automated loading process, but also greatly improves production efficiency and convenience.

[0031] Reference Figure 1 and Figure 3 The positioning mechanism 2 includes a connecting frame 201, the front side of the connecting frame 201 is fixedly connected to the rear end of the fixing frame 3, the top of the connecting frame 201 is fixedly connected to a driving motor 204, the output end of the driving motor 204 is fixedly connected to a gear 203, the bottom of the gear 203 is meshedly connected to a sawtooth bar 202, the bottom of the sawtooth bar 202 is fixedly connected to a connecting rod 206, the end of the connecting rod 206 is installed with a push plate 205, and the top right side of the workbench 1 is fixedly connected to a limiting plate 207; the middle part of the connecting frame 201 is installed with a slide rail 14, and the sawtooth bar 202 is slidably connected to the slide rail 14;

[0032] Specifically, when the position of the workpiece needs to be located, the drive motor 204 is started and the drive gear 203 is rotated; the rotation of the gear 203 is meshed with the sawtooth bar 202 for transmission, and this transmission method ensures the accurate transmission of power and the smoothness of movement. When the sawtooth bar 202 moves, it slides in the slide rail 14, which not only ensures the stability of the movement of the sawtooth bar 202, but also plans its movement trajectory; the movement of the sawtooth bar 202 further drives the synchronous movement of the connecting rod 206 and the push plate 205; this synchronization mechanism ensures the precise movement of the push plate 205, so that the workpiece can be accurately pushed to the limit plate 207; the limit plate 207 is a key component for positioning, and its precise position and stable performance are crucial for the positioning of the workpiece; when the workpiece is pushed to the limit plate 207, the workpiece will fit closely to the limit plate 207, thereby achieving precise positioning of the workpiece.

[0033] Reference Figure 1 and Figure 3 , pillars 6 are installed at the four corners of the bottom of the workbench 1; a bottom pad 5 is installed at the end of the pillar 6; a slot 15 is opened on the top of the push plate 205, and the slot 15 is engaged with the end of the connecting rod 206;

[0034] Specifically, the coordination between the support column 6 and the bottom pad 5 is improved, thereby increasing the stability of the device when supported. The shape and size of the push plate 205 can be replaced by engaging the connecting rod 206 with the card slot 15 .

[0035] Working principle: When using a fixture to process a workpiece, place the workpiece to the left side of the workbench 1, turn on the industrial fan 8 to drive the air intake pipe 13 and the air collecting plate 9 to intake air, and increase the adsorption space range through the air collecting plate 9. At the same time, turn on the electric push rod 2 10 to drive the air intake pipe 13 and the air collecting plate 9 to move downward, and adsorb the workpiece through the air collecting plate 9. After the electric push rod 2 10 retracts and lifts, turn on the electric push rod 1 12 to drive the fixed ring 11 to move to the right, and at the same time turn on the conveyor belt assembly 4 for operation. When the air collecting plate 9 moves to the upper position of the conveyor belt assembly 4, turn off the industrial fan 8, so that the workpiece naturally falls on the conveyor belt assembly 4 for transmission, thereby completing the automated loading process, which is more time-saving and labor-saving. The production efficiency is improved and the needs of use can be met. When positioning the position of the workpiece, the drive motor 204 is turned on to drive the gear 203 to rotate. The gear 203 rotates and meshes with the sawtooth bar 202 to drive the sawtooth bar 202 to move. When the sawtooth bar 202 moves, it slides in the slide rail 14, and the movement trajectory of the sawtooth bar 202 is planned. The movement of the sawtooth bar 202 causes the connecting rod 206 to move synchronously with the push plate 205. The push plate 205 moves to the left to push the workpiece to the limit plate 207, so that the workpiece is parallel to the limit plate 207 to complete the positioning process of the workpiece. The workpiece positioning work can be carried out while loading, which brings convenience to use.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
