Timing gears are gears that play a role in time scale positioning in mechanical devices to complete related control functions. Timing gears are produced using powder metallurgy technology, and the loading and unloading steps are mostly carried out using special loading and unloading devices.

However, the automatic loading and unloading stroke of this structure is long, the degree of automation is low, and the loading and unloading speed is slow. Utility Model Content

[0016] The loading and unloading device for heat treatment of powder metallurgy timing gears is provided with a slider, a center shaft, a rear baffle and a direction-changing rack. When the device is loading and unloading, the operator controls the electric cylinder through an external control unit. The operator places the loading and unloading materials at appropriate positions on the upper and lower sides of the center shaft and then starts the electric cylinder. The electric cylinder applies pressure upward through a push rod. After the slider is pressed, it slides upward through a limit slide bar. The slider drives the center shaft to move in the same direction. The direction-changing gear on the outer periphery of the rear end of the center shaft contacts the direction-changing rack during the upward movement. The center shaft is driven to rotate through the meshing of the tooth grooves until the slider moves When the stroke reaches the maximum, the adsorption mechanism points vertically upward and adsorbs the material placed above, and then the electric cylinder resets the push rod, which pulls the slider downward until the slider reaches the maximum stroke downward. The median axis and the adsorption mechanism rotate through the contact between the changing gear and the changing rack. At this time, the adsorption mechanism points vertically downward, and the material transfer is completed after the adsorption stops. The working principle of loading and unloading is the same, and you only need to repeat the above steps in reverse. Through the above steps, the equipment can not only greatly improve the degree of automation of loading and unloading, but also significantly improve the efficiency of loading and unloading operations compared to the existing loading and unloading structure with a longer stroke.

[0024] A median shaft 4 is also provided in the middle of the main frame 1, and the median shaft 4 carries the installation of the adsorption mechanism 402. A rear baffle 5 is provided at the rear end of the main frame 1, and the rear baffle 5 carries the installation of the direction-changing rack 6. The inner end surface of the rear baffle 5 is provided with a direction-changing rack 6, and the direction-changing rack 6 contacts the direction-changing gear 401 to rotate the median shaft 4.

[0025] The center shaft 4 further includes a direction-changing gear 401 and an adsorption mechanism 402 . The direction-changing gear 401 is fixedly connected to the periphery of the rear end of the center shaft 4 . The adsorption mechanism 402 is laterally fixedly connected to the side end of the center shaft 4 and extends outward.

[0026] In this embodiment, the main frame 1 further includes a limit slide bar 101 and a slider 102. The limit slide bar 101 is fixedly mounted on the inner end surface of the main frame 1 and is vertically distributed up and down. The slider 102 is penetrated by the limit slide bar 101 and has a sliding connection relationship with the limit slide bar 101. The median axis 4 penetrates the slider 102 horizontally, and a bearing structure exists at the position connected to the inside of the slider 102. The median axis 4 establishes a movable connection relationship with the slider 102 through the bearing structure.

[0027] Specifically, by providing a bearing structure inside the position where the middle shaft 4 is connected to the slider 102, the middle shaft 4 can rotate more smoothly.

[0028] In this embodiment, the bottom of the push rod 3 passes through the lower end of the main frame 1 and is movably connected to the electric cylinder 2. The bottom end of the slider 102 is fixedly connected to the top of the push rod 3. The adsorption mechanism 402 is pre-debugged so that when the direction-changing gear 401 is at the maximum stroke position at the upper and lower ends of the direction-changing rack 6, it is in a vertical upward state and a vertical downward state respectively.

[0029] Specifically, the adsorption mechanism 402 facing vertically upward or vertically downward is more suitable for loading and unloading operations;

[0030] In this embodiment, the adsorption method of the adsorption mechanism 402 is not limited and can be customized according to actual needs; the rear baffle 5 is movably connected to the rear end of the main frame 1 through a bolt-like structure, and the middle part is hollowed out, and strip-shaped reserved grooves are opened on the upper and lower sides of the changing gear 401.

[0031] The working principle and use process of the utility model are as follows: when the equipment is loading and unloading, the operator controls the electric cylinder 2 through the external control unit. The operator places the loading and unloading materials at appropriate positions on the upper and lower sides of the center axis 4 and then starts the electric cylinder 2. The electric cylinder 2 applies pressure upward through the push rod 3. After the slider 102 is pressed, it slides upward through the limit slider 101. The slider 102 drives the center axis 4 to move in the same direction. The direction-changing gear 401 on the outer periphery of the rear end of the center axis 4 contacts the direction-changing rack 6 during the upward movement, and the meshing of the tooth grooves makes the center axis 4 move in the same direction. The center axis 4 is driven to rotate until the slider 102 moves to the maximum stroke. At this time, the adsorption mechanism 402 is vertically upward and adsorbs the material placed above. Then the electric cylinder 2 resets the push rod 3, and the push rod 3 pulls the slider 102 downward until the slider 102 reaches the maximum stroke downward. The center axis 4 and the adsorption mechanism 402 rotate through the contact between the changing gear 401 and the changing rack 6. At this time, the adsorption mechanism 402 is vertically downward, and the material transfer is completed after the adsorption stops. The working principle of loading and unloading is the same, and only the above steps need to be repeated in reverse.
