[0004] The gear plate is easily offset when placed on the surface of the gear plate positioning plate, which reduces the processing accuracy of the gear plate pin riveting fixed to the gear plate, thereby reducing the processing quality of the gear plate. Utility Model Content

[0005] In order to improve the problem that the gear plate is easily offset on the surface of the gear plate positioning plate, the present application provides a gear plate shaft riveting machine.

[0006] This application provides a gear plate shaft riveting machine, which adopts the following technical solutions:

[0007] A gear plate shaft riveting machine includes a base, a turntable and multiple limit devices. The turntable is rotatably connected to the surface of the base. Multiple limit devices are connected to the turntable surface at intervals around the turntable axis. The limit device includes a limit plate and a limit ring capsule. The limit plate is connected to the turntable surface. The limit plate surface is provided with a limit cavity for the gear plate to be embedded. The outer ring of the limit ring capsule is connected to the inner wall of the limit cavity. The inner ring of the limit ring capsule can press against the outer periphery of the gear plate to form a limit.

[0008] By adopting the above technical solution, when the gear plate is embedded in the limiting cavity, the inner ring of the limiting ring capsule presses against the outer periphery of the gear plate to form a limit, so that the gear plate is not easily offset during processing, and the processing accuracy of the gear plate needle riveting on the gear plate surface is improved, thereby improving the processing quality of the gear plate; at the same time, the limiting ring capsule has a certain elasticity. When the gear plate is out of the limiting cavity, the gear plate surface squeezes the inner ring of the limiting ring capsule, and the limiting ring capsule is deformed under pressure, reducing the wear between the gear plate surface and the inner ring wall of the limiting ring capsule, and further improving the processing quality of the gear plate.

[0009] Optionally, the limiting device also includes an inflation component, which includes an inflation piston and an elastic member. The bottom wall of the limiting cavity is provided with a sliding cavity for the inflation piston to slide. The sliding direction of the inflation piston and the axis of the turntable are parallel to each other. One end of the elastic member in the elastic direction is connected to the bottom wall of the sliding cavity, and the other end of the elastic member in the elastic direction is connected to the surface of the inflation piston. The elastic member has the elastic force to drive the inflation piston to slide in the direction away from the sliding cavity, and the end of the inflation piston tends to protrude from the bottom wall of the sliding cavity. The sliding cavity is connected to the inner cavity of the limiting ring bag.

[0010] By adopting the above technical solution, when the gear plate is embedded in the limiting cavity, the surface of the gear plate abuts against the surface of the inflatable piston, and the inflatable piston slides toward the direction close to the sliding cavity under the pressure of the gear plate, the air pressure in the sliding cavity increases, and the sliding cavity is connected to the inner cavity of the limiting ring bag. The air in the sliding cavity enters the inner cavity of the limiting ring bag, and the inner ring of the limiting ring bag is pressurized and expanded and presses against the outer periphery of the gear plate to form a limit, so that the gear plate is not easy to deviate in the sliding cavity, thereby improving the processing accuracy of the gear plate; when the gear plate is out of the limiting cavity, the pressure on the inflatable piston by the gear plate disappears, and the elastic force of the elastic member drives the inflatable piston to slide in the direction away from the sliding cavity, and the end of the inflatable piston protrudes from the inner wall of the limiting cavity, thereby realizing automatic resetting of the inflatable piston.

[0011] Optionally, a buffer surface is provided on the end surface of the inflation piston protruding from the bottom wall of the sliding cavity. The buffer surface is in the shape of a circular arc protrusion and can abut against the surface of the gear plate.

[0012] By adopting the above technical solution, the buffer surface can abut the gear plate surface, and the buffer surface is in the shape of a circular arc convexity, reducing the wear between the gear plate surface and the buffer surface, thereby ensuring the processing quality of the gear plate.

[0013] Optionally, the limiting device also includes a cleaning piston and a transmission member. The bottom wall of the limiting cavity is provided with a cleaning cavity for the cleaning piston to slide. The transmission member is connected between the inflation piston and the cleaning piston. The transmission member can receive power from the inflation piston and drive the cleaning piston to slide.

[0014] By adopting the above technical solution, when the inflatable piston slides on the inner wall of the sliding chamber, the transmission part receives the power of the inflatable piston and drives the cleaning piston to slide. The cleaning piston drives the air in the cleaning chamber into the limiting chamber and impacts the gear plate surface, taking away impurities on the gear plate surface, thereby achieving preliminary cleaning of the gear plate surface.

[0015] Optionally, the transmission member is a transmission gear, and a transmission chamber is provided on the inner wall of the cleaning chamber for the transmission gear to rotate, and the transmission chamber connects the cleaning chamber and the sliding chamber, and a tooth groove 1 is provided on the surface of the cleaning piston for meshing with the transmission gear, and a tooth groove 2 is provided on the surface of the inflation piston for meshing with the transmission gear, and the cleaning piston and the inflation piston are located on both sides of the transmission gear. When the inflation piston slides toward the direction close to the sliding chamber, the transmission gear rotates, driving the cleaning piston to slide toward the direction away from the cleaning chamber.

[0016] By adopting the above technical solution, when the gear plate is embedded in the limiting cavity, the inflatable piston slides toward the sliding cavity under the pressure of the gear plate, the inner wall of the second tooth groove engages the transmission gear, driving the transmission gear to rotate, and the inner wall of the first tooth groove engages the transmission gear, driving the cleaning piston to slide toward the direction away from the cleaning cavity, driving the air in the cleaning cavity into the limiting cavity and impacting the gear plate surface, taking away impurities on the gear plate surface, and realizing automatic cleaning of the gear plate.

[0017] Optionally, a filter is connected to the inner wall of the cleaning chamber, and the filter can filter impurities in the air.

[0018] By adopting the above technical solution, the filter can filter impurities in the air, making it difficult for the impurities to enter the cleaning chamber, thereby ensuring the cleanliness of the cleaning chamber.

[0019] Optionally, a positioning groove for embedding the filter is provided on the inner wall of the cleaning chamber, and the circumferential outer wall of the filter can press against the inner wall of the positioning groove to form a limit.

[0020] By adopting the above technical solution, the circumferential outer wall of the filter is pressed against the inner wall of the positioning groove to form a limit. When the filter needs to be cleaned, the filter is driven out of the positioning groove to realize the separation of the filter and the limit plate, thereby facilitating the cleaning of the filter.

[0021] Optionally, a magnetic component is embedded on the surface of the filter, and the magnetic component can absorb impurities.

[0022] By adopting the above technical solution, the magnetic part is embedded in the surface of the filter screen, and the magnetic part can absorb impurities on the surface of the filter screen, thereby realizing the directional collection of impurities on the surface of the filter screen.

[0023] Optionally, a collection groove for embedding magnetic components is provided on the surface of the filter, and the collection groove can accommodate impurities.

[0024] By adopting the above technical solution, the magnetic member is embedded in the collection tank, and the impurities adsorbed by the magnetic member are accumulated in the collection tank, thereby realizing the collection of the impurities in the collection tank.

[0025] Optionally, the magnetic part is an electromagnet, and an induction switch is embedded in the inner wall of the positioning groove. The induction switch is electrically connected to the electromagnet. When the induction switch abuts against the filter surface and is turned on, the electromagnet is energized and becomes magnetic.

[0026] By adopting the above technical solution, when the filter is removed from the positioning groove, the abutment effect of the filter on the induction switch disappears, the electromagnet is powered off and loses its magnetism, the adsorption force of the electromagnet on impurities disappears, and the impurities accumulate in the collection groove, thereby facilitating the cleaning of impurities in the collection groove.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The setting of the limiting ring pocket makes it difficult for the gear plate to deviate during the processing, improves the processing accuracy of the gear plate needle riveting on the gear plate surface, and thus improves the processing quality of the gear plate;

[0029] 2. The arrangement of the inflatable piston and the elastic member causes the inner ring of the limiting ring to expand during pressurization and press against the outer periphery of the gear plate to form a limit, making it difficult for the gear plate to deviate in the sliding cavity, thereby improving the machining accuracy of the gear plate;

[0030] 3. The cleaning piston and transmission parts are set up. The cleaning piston drives the air in the cleaning chamber into the limit chamber and impacts the gear plate surface, taking away impurities on the gear plate surface, thereby achieving preliminary cleaning of the gear plate surface.
