Description

Technical Field

[0001] This invention relates to the field of shaft housing manufacturing technology, specifically to an automatic shaft housing pressing and testing machine and method. Background Technology

[0002] Currently, defective products inevitably appear during the pressing process of shaft housings. The existing technology involves manually inspecting the shaft housings for defects before pressing, relying on the operator's experience. This requires highly experienced personnel and is inefficient, taking an average of 30-60 seconds to check if a shaft housing is defective. Even with manual inspection, a small number of defective products remain among the good ones, indicating low accuracy. Therefore, those skilled in the art have proposed a testing machine and method that uses optical sensors to automatically distinguish between good and bad shaft housings. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an automatic shaft housing pressing and testing machine and method, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] In a first aspect, the present invention provides an automatic shaft housing pressing and testing machine, including a base, and further comprising:

[0006] A pressing mechanism is fixedly installed on the upper part of the base. It is used to press the product while selecting out unqualified products. The pressing mechanism includes a fixture base for placing several shaft housings.

[0007] The rejection mechanism is fixedly installed on the upper part of the base and is used to remove the unqualified products selected by the pressing mechanism during pressing.

[0008] A limiting frame is fixedly installed on the upper part of the base, the fixture base is located in the limiting frame, and the fixture base can move within the limiting frame;

[0009] The feed cylinder is fixedly installed on the edge of the limiting frame, and its telescopic end is connected to the fixture base, driving the fixture base to reciprocate inside the limiting frame.

[0010] Furthermore, the pressing mechanism includes a stamping machine and a fixture base located directly below the lifting end of the stamping machine. A fixture core is movably arranged inside the fixture base, and a shaft housing to be pressed is placed inside the fixture core. A lifting plate is installed on the lifting end of the stamping machine, and several spring limit plates are arranged below the lifting plate.

[0011] Furthermore, a photoelectric sensor is provided on the front bottom side of the stamping machine, an upper baffle is installed on the rear end face of the lifting plate, and a lower baffle is installed on the rear end face of the spring limiting plate.

[0012] Furthermore, a gap is reserved between the upper and lower shielding plates for the conduction of the optical path of the photoelectric sensor. Under normal conditions, the lower shielding plate blocks the optical path, and when pressed into place, the upper shielding plate blocks the optical path.

[0013] Furthermore, a sensor mounting bracket is installed at the bottom of the stamping machine, and the photoelectric sensor is mounted on the sensor mounting bracket.

[0014] Furthermore, the lifting plate and the spring limiting plate are connected by a movable guide rod, which slides inside the lifting plate, and a spring is sleeved on the outside of the movable guide rod and located between the lifting plate and the spring limiting plate.

[0015] Furthermore, a pressing head mounting plate is installed at the bottom end of the spring limiting plate, and a pressing head is installed at the bottom end of the pressing head mounting plate.

[0016] Furthermore, the photoelectric sensor includes a laser emitter and a laser receiver, and the upper and lower baffles pass between the laser emitter and the laser receiver when the upper and lower baffles move vertically.

[0017] Furthermore, the rejection mechanism includes a bracket installed at the top of the base, a linear drive module installed at the top of the bracket, a lifting cylinder installed at the drive end of the linear drive module, an air nozzle mounting plate installed at the telescopic end of the lifting cylinder, and a plurality of suction air nozzles for adsorbing defective products installed inside the air nozzle mounting plate.

[0018] Secondly, the present invention also proposes a testing method for an automatic shaft housing pressing testing machine, comprising the following steps:

[0019] S1. Place the jig core with several shaft shells in the jig base;

[0020] S2. The feed cylinder extends, pushing the fixture base to move directly below the pressing head;

[0021] S3. The press pushes each pressing head to press down each shaft housing synchronously. During the pressing process, the photoelectric sensor corresponding to each shaft housing detects whether the shaft housing is pressed down to the correct position. Shaft housing that is pressed down to the correct position is a qualified product, otherwise it is an unqualified product.

[0022] S4. After pressing, the feed cylinder retracts and pulls out the fixture base;

[0023] S5. The linear drive module drives the lifting cylinder to the end, and the suction nozzle corresponding to the unqualified shaft housing will generate suction, thereby removing the unqualified shaft housing and completing the inspection.

[0024] This invention provides an automatic shaft housing pressing and testing machine and method. Compared with the prior art, it has the following advantages:

[0025] This automatic shaft housing pressing and inspection machine and method automatically detects whether each shaft housing is defective by using photoelectric sensors during the pressing process. Compared with the existing manual method, it is not only more efficient, but also significantly improves accuracy, making it suitable for mass production in enterprises. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-2 This invention provides a technical solution: an automatic shaft housing pressing and inspection machine, including a base 1, a pressing mechanism 2, a rejection mechanism 3, a limiting frame 4, and a feeding cylinder 5. The pressing mechanism 2 is fixedly installed on the upper part of the base 1 and is used to press the products while selecting out unqualified products. The pressing mechanism 2 includes a fixture base 22 for placing a plurality of shaft housings 214. The rejection mechanism 3 is fixedly installed on the upper part of the base 1 and is used to remove the unqualified products selected by the pressing mechanism 2 during pressing. The limiting frame 4 is fixedly installed on the upper part of the base 1, and the fixture base 22 is located in the limiting frame 4 and can move within the limiting frame 4. The feeding cylinder 5 is fixedly installed on the edge of the limiting frame 4, and its telescopic end is connected to the fixture base 22, driving the fixture base 22 to reciprocate within the limiting frame 4.

[0036] Please see Figure 3-6The pressing mechanism 2 includes a press 21 (the structure and principle of the press 21 are known technologies and will not be described in detail here) and a fixture base 22 located directly below the lifting end of the press 21. A fixture core 213 is movably disposed inside the fixture base 22. Several fixture slots are opened inside the fixture core 213, and each fixture slot contains a shaft housing 214 to be pressed (the shaft housing 214 is adapted to the fixture slot). A lifting plate 25 is installed on the lifting end of the press 21 (when the lifting end of the press 21 is in operation...). This will cause the lifting plate 25 to rise and fall, thereby completing the pressing work on the shaft housing 214. Several spring limit plates 27 are set below the lifting plate 25. A photoelectric sensor 24 is set on the front side of the bottom of the stamping machine 21. An upper baffle plate 211 is installed on the rear end face of the lifting plate 25, and a lower baffle plate 212 is installed on the rear end face of the spring limit plates 27. A gap is reserved between the upper baffle plate 211 and the lower baffle plate 212 for the conduction of the optical path of the photoelectric sensor 24. Under normal conditions, the lower baffle plate 212 blocks the optical path, and the pressing is in place. At this time, the upper baffle plate 211 blocks the light path. A sensor mounting bracket 23 is installed at the bottom of the stamping machine 21. The photoelectric sensor 24 is installed on the sensor mounting bracket 23. The lifting plate 25 and the spring limiting plate 27 are connected by a movable guide rod 26. The movable guide rod 26 slides inside the lifting plate 25. A spring 28 is sleeved outside the movable guide rod 26 and between the lifting plate 25 and the spring limiting plate 27 (both the lifting plate 25 and the spring limiting plate 27 have columnar openings to accommodate the spring 28 and the movable guide rod 26). The limiting groove limits the lateral position of the spring 28, allowing only the spring 28 to extend and retract. The bottom end of the spring limiting plate 27 is equipped with a pressing head mounting plate 29, and the bottom end of the pressing head mounting plate 29 is equipped with a pressing head 210. The photoelectric sensor 24 includes a laser emitting end and a laser receiving end (when working, the laser emitting end will emit a laser beam to the laser receiving end, which is existing known technology and will not be described in detail here). When the upper baffle plate 211 and the lower baffle plate 212 move vertically, they will pass between the laser emitting end and the laser receiving end.

[0037] Please see Figure 7 The rejection mechanism 3 includes a bracket 31 mounted on the top of the base 1. A linear drive module 32 is mounted on the top of the bracket 31 (the specific structure and working principle of the linear drive module 32 are known technologies and will not be described in detail here). A lifting cylinder 33 is mounted on the drive end of the linear drive module 32. An air nozzle mounting plate 34 is mounted on the telescopic end of the lifting cylinder 33. Several suction nozzles 35 for adsorbing unqualified products are installed inside the air nozzle mounting plate 34 (the suction nozzles 35 are connected to an external vacuum solenoid valve through an air pipe. The vacuum solenoid valve can control the corresponding suction nozzle 35 to generate negative pressure, which is known technology and will not be described in detail here).

[0038] In addition, the above-mentioned automatic shaft housing pressing and testing machine includes the following testing steps:

[0039] S1. Place the jig core 213 with several shaft shells 214 in the jig base 22;

[0040] S2, the feed cylinder 5 extends, pushing the fixture base 22 to move directly below the pressing head 210;

[0041] S3. The press 21 pushes each pressing head 210 to press down each shaft housing 214 synchronously. During the pressing process, the photoelectric sensor 24 corresponding to each shaft housing 214 detects whether the shaft housing 214 is pressed down in place. The shaft housing 214 that is pressed down in place is a qualified product, otherwise it is an unqualified product.

[0042] S4. After pressing, the feed cylinder 5 retracts and pulls out the fixture base 22;

[0043] S5. The linear drive module 32 drives the lifting cylinder 33 to the end, and the suction nozzle 35 corresponding to the unqualified shaft housing 214 will generate suction, thereby removing the unqualified shaft housing 214 and completing the inspection.

[0044] In use, first place several shaft housings 214 in each fixture slot, and then place the entire fixture core 212 in the fixture base 22. At this time, control the feeding cylinder 5 to extend, and the feeding cylinder 5 pushes the fixture base 22 to move directly below the pressing head 210 (moving in the limiting frame 4).

[0045] When not compressed, the state is as follows Figure 4 As shown, the lower baffle 212 blocks the light path of the photoelectric sensor 24. When the press 21 pushes the lifting plate 25 downward, the movable guide rod 26, spring limit plate 27, spring 28, pressing head mounting plate 29, pressing head 210, upper baffle 211, and lower baffle 212 will all move downward synchronously. When the pressing head 210 contacts the top of the shaft housing 214, the spring 28 is compressed. The pressure at this time comes from the reaction force of the spring 28, and the state at this time is as follows. Figure 5 As shown, the photoelectric sensor 24 is located between the upper shield 211 and the lower shield 212, and the optical path can be conducted.

[0046] Then, it continues to move down, and the state becomes like... Figure 6As shown, while the spring 28 is compressed, the lifting plate 25 descends to contact the spring limiting plate 27. At this time, the pressing force on the shaft housing 214 is not only the reaction force of the spring 28, but also the pressure generated by the press 21. At this time, the light path is blocked by the upper baffle plate 211. In the industry, this state can be called the complete pressing of the shaft housing 214. If the pressing process is only based on the reaction force of the spring 28, then the shaft housing 214 is a defective product and needs to be rejected. Thus, when pressing multiple shaft housings 214, the photoelectric sensor 24 can be used to determine which shaft housing 214 is a defective product.

[0047] Subsequently, the linear drive module 32 drives the lifting cylinder 33 to move to the rightmost end. The lifting cylinder 33 extends, pushing the nozzle mounting plate 34 and several suction nozzles 35 downward until they contact the shaft housing 214. The suction nozzle 35 corresponding to the defective shaft housing 214 will generate suction to adsorb and fix the defective shaft housing 214 and remove it.
