Description

Technical Field

[0001] The present invention relates to a processing device, and more particularly to a pump core pressing device. Background Art

[0002] In the existing method of pressing steel balls into the pump core of an automotive engine, manual feeding is adopted. Before placing the product into the tooling, the steel balls are placed first. For the pressing, the steel balls are placed below and the product is placed above. Since the steel balls are small, it is very easy to place too many of them, and it is difficult to take them out after being placed. Whether manually pressed or machine-pressed, the accuracy is not high. However, the quantity of the pump cores of automotive engines is large and the accuracy requirements are high. Relying entirely on manual operation not only easily causes quality problems but also has low efficiency.

[0003] Therefore, it is urgent to solve the above problems. Summary of the Invention

[0004] Object of the Invention: The object of the present invention is to provide a pump core pressing device with high pressing efficiency.

[0005] Technical Solution: To achieve the above object, the present invention discloses a pump core pressing device, which includes a feeding conveying device for circulating and transporting the products to be pressed in a "mouth" shape, and a multi-station turntable located beside the feeding conveying device for sequentially pressing steel columns or steel balls onto the products at multiple stations and performing detection and storage. The multi-station turntable includes a turntable frame located beside the feeding conveying device, a multi-station turntable assembly located on the turntable frame and having multiple stations for placing the products to be pressed, a press assembly correspondingly arranged on the turntable frame at one station for pressing the steel columns or steel balls onto the products, a detection assembly correspondingly arranged on the turntable frame at one station for detecting the pressing height, a loading robotic arm located on the turntable frame for grasping the products to be pressed to the stations of the multi-station turntable assembly, a unloading robotic arm located on the turntable frame for grasping the products after pressing from the stations of the multi-station turntable assembly, and a bin assembly located on the turntable frame for placing the products after pressing.

[0006] Among them, the feeding conveying device includes two parallel feeding conveying line bodies, a lifting and translation mechanism located at the left and right ends of the feeding conveying line bodies for circulating the product matching trays to the adjacent feeding conveying line bodies, a positioning mechanism located at the feeding place of the feeding conveying line bodies for positioning the feeding tooling at the feeding place, a blocking mechanism located on the feeding conveying line bodies for ensuring the sequential arrangement of the feeding tooling, a tooling stop limit mechanism located at both ends of the feeding conveying line bodies for restricting the pause at the tooling gear positions, and a feeding tooling located on the feeding conveying line bodies for placing the products to be pressed.

[0053] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0054] like Figure 1 and Figure 2As shown in the figure, a pump core pressing device of the present invention includes a feeding and conveying device and a multi-station turntable. The feeding and conveying device is used to convey the products to be pressed in a "mouth" - shaped flow. The feeding and conveying device includes a feeding and conveying line body 8, a lifting and translation mechanism 9, a positioning mechanism 10, a blocking mechanism 11, a tooling stop and limit mechanism 12, and a blanking tooling 13. Two feeding and conveying line bodies 8 are arranged in parallel. The feeding and conveying line body 8 includes a frame, a conveying motor, a worm and worm gear reducer, a main power shaft, a secondary power shaft, a synchronous belt, a nylon friction strip, and nylon stop strips. The frame is composed of aluminum alloy profiles. The conveying motor is arranged on the frame. The worm and worm gear reducer is connected to the output shaft of the conveying motor. The main power shaft is connected to the output shaft of the worm and worm gear reducer. The main power shaft is erected on the frame. The secondary power shaft is erected on the frame. The secondary power shaft is arranged opposite to the main power shaft. The synchronous belt is wound between the main power shaft and the secondary power shaft. The nylon friction strip is located on the synchronous belt. The nylon stop strips are located on both sides of the frame. The nylon stop strips are used to prevent deviation. The feeding and conveying line body builds the frame with aluminum alloy profiles. There are two rows of holes on the aluminum alloy profiles. Each component is fixed together through T - shaped nuts and bolts. The feeding and conveying line body is driven by the conveying motor plus the worm and worm gear reducer to drive the main power shaft to rotate and drive through the synchronous pulley and synchronous belt. There is a nylon friction strip under the synchronous belt, which can reduce the friction and increase the belt life. There are nylon stop strips on both sides of the synchronous belt, which can prevent the tooling plate from deviating on the conveying line.

[0055] As Figure 3 and Figure 4As shown, the lifting and shifting mechanism 9 is located at both ends of the feeding conveyor line 8. The lifting and shifting mechanism 9 is used to transfer product-matching pallets to adjacent feeding conveyor lines 8. The lifting and shifting mechanism 9 includes a support plate 901, a support profile 902, a cylinder fixing plate 903, a lifting and shifting cylinder 904, a lifting base plate 905, a lifting plate 906, a lifting linear guide rail 907, a reinforcing rib 908, a motor fixing plate 909, a drive motor 910, a first pulley 911, a drive shaft 912, a second pulley 913, a drive belt 914, a belt cover plate 915, a support rod 916, a synchronous pulley 917, a driven shaft 918, a driven roller 919, an auxiliary roller 920, a transmission belt 921, a blocking limit plate 922, and a sensor 923. Two support plates 901 are arranged opposite each other, and both support plates 901 are connected to the feeding conveyor line 8. A support profile 902 is used to connect the two support plates 901. A cylinder fixing plate 903 is fixed to the support profile 902. A lifting and shifting cylinder 904 is fixed to the cylinder fixing plate 903. The piston rod of the lifting and shifting cylinder 904 can extend upwards. A lifting base plate 905 is connected to the end of the piston rod of the lifting and shifting cylinder 904. A lifting plate 906 is located at the left and right ends of the lifting base plate 905. A lifting linear guide rail 907 is connected to the lifting plate 906 and the support plates 901. The lifting linear guide rail 907 can drive the lifting plate 906 to move up and down. A reinforcing rib 908 is set between the lifting base plate 905 and the lifting plate 906. A motor fixing plate 908 is also present. 09 is located on the upper surface of the lifting base plate 905. The drive motor 910 is fixed on the motor mounting plate 909. The first pulley 911 is connected to the output shaft of the drive motor 910. The drive shaft 912 is mounted between the two lifting plates 906. The second pulley 913 passes through the drive shaft 912. The drive belt 914 is wound around the first pulley 911 and the second pulley 913. The belt cover plate 915 is located on the lifting base plate 905 and is used to protect the drive belt 914. The support rod 916 is located on the lifting base plate 905 and is used to support the belt cover plate 915. Two synchronous pulleys 917 are symmetrically arranged and pass through the drive shaft 912. The driven shaft 918 is mounted between the two lifting plates 906. Driven shaft 918 is parallel to drive shaft 912. Driven roller 919 passes through driven shaft 918 and is correspondingly arranged with synchronous pulley 917. Auxiliary roller 920 passes through lifting plate 906 and is correspondingly arranged with synchronous pulley 917. Transmission belt 921 is wound around synchronous pulley 917, auxiliary roller 920, and driven roller 919. Blocking limit plate 922 is fixed to lifting base plate 905. Sensor 923 is located on blocking limit plate 922. The piston rod of lifting and translating cylinder 904 extends, driving lifting base plate 905 to rise. Lifting plate 906 rises along lifting linear guide rail 907. Unloading fixture 13 is arranged above transmission belt 921 and rises together with transmission belt 921.When the unloading fixture 13 is raised to a height exceeding the guardrails on both sides of the feeding conveyor line 8, the sensor 923 on the lifting and shifting cylinder 904 outputs a signal, and the drive motor 910 drives the transmission belt 921 to rotate through the drive belt 914, causing the unloading fixture 13 to move forward until it falls onto the adjacent feeding conveyor line 8. The unloading fixture 13 moves to the blocking limit plate 922, and the sensor 923 on the blocking limit plate 922 detects that the unloading fixture 13 has reached its position. The drive motor 910 stops moving, and the lifting and shifting cylinder 904 drives the lifting base plate 905 to descend. The lifting upright plate 906 returns to its original position along the lifting linear guide rail 907. The lifting and shifting cylinder extends, driving the lifting base plate and lifting upright plate to rise via the lifting linear guide rail. The unloading fixture rises together on the transmission belt. Once the unloading fixture's height exceeds the guardrails on both sides of the conveyor line, the sensor on the lifting and shifting cylinder outputs a signal, and the drive motor moves the transmission belt forward via the drive belt. When the unloading fixture reaches the stop limit plate, a proximity sensor on the stop limit plate detects that the unloading fixture has reached its position. The drive motor stops, the lifting and shifting cylinder drives the lifting base plate and lifting upright plate back to their original positions via the lifting linear guide rail, and the remaining components follow suit. The unloading fixture then falls onto the conveyor line.

[0056] like Figure 5 As shown, the positioning mechanism 10 is located at the loading point of the feeding conveyor line 8. The positioning mechanism 10 is used to position the unloading fixture 13 at the loading point. The positioning mechanism 10 includes a positioning cylinder mounting plate 1001, a positioning cylinder 1002, a connecting plate 1003, and a positioning pin 1004. The positioning cylinder mounting plate 1001 is fixed to the end of the feeding conveyor line 8. The positioning cylinder 1002 is located on the positioning cylinder mounting plate 1001. The connecting plate 1003 is connected to the extended end of the positioning cylinder 1002. The positioning pin 1004 is located on the connecting plate 1003. The positioning pin 1004 is used to insert into the unloading fixture 13. The unloading fixture 13 has a positioning hole 1301 corresponding to the positioning pin 1004. When the unloading fixture 13 is in place, the positioning cylinder 1002 extends, so that the positioning pin 1004 is inserted into the positioning hole of the unloading fixture 13, so that the unloading fixture 13 is positioned at the loading point. The positioning cylinder mounting plate is installed on the feeding conveyor line.

Vertical linear guides are fixed on the press frame to ensure straightness and repeatability during the pressing process. A steel ball pressing fixture, a steel column pressing fixture, a pressing rivet, a pressure sensor, and a protective cylinder are sequentially installed on the vertical linear guides. The pressing method of this invention is from bottom to top. An electric push rod is placed below the press to push the fixtures on the turntable fixture upward. The steel ball is fed to the steel ball pressing fixture through a pipe via a steel ball feeding assembly. The steel column is fed into the steel ball pressing fixture through a pipe. The tracks of the steel ball pressing fixture and the steel column pressing fixture have elastic balls inside, which allows the steel ball or steel column to be fed into the steel ball pressing fixture and the steel column pressing fixture in advance without falling off. The product is positioned upwards by the bottom contouring of the steel ball and steel column pressing fixtures. Continuing upwards, the pressing head, guided by the internal guides of these fixtures, presses the product and steel balls together. Initially, the steel ball and steel column pressing fixtures descend to a designated position via limit rods. Pressure sensors record the pressure during pressing; if the pressure is too high or too low, it is recorded and reported. A protective cylinder remains in a depressed state to prevent damage to the rivet head or product from abnormal pressing pressure. The steel ball and steel column pressing fixtures can be manually switched via the rear guide rail and secured with elastic pins. The steel balls and steel columns are fed by the steel ball feeding assembly, and external steel column and steel ball sensors detect whether feeding is complete.
