[0129] The function of the movable baffle device is that when the cylinder is pushed from position 1 of the placement area inside the equipment to position 2 of the support device working area, the movable baffle uses the deformation of the double torsion spring to avoid the cylinder, and automatically resets after the cylinder moves away.

[0130] Considering the effects of liquid corrosion and aluminum shavings buildup, which prevent the rollers from rotating and increase friction tenfold when pushing the cylinder, accompanied by a bouncing sensation, this invention abandons the rollers and uses a stainless steel slide rail. The main body of the 45# steel slide rail is designed to be 20mm long, 500mm wide, 20mm high, and 40mm high, with two sections at the top. Stepped holes, recessed platforms 30mm deep, with a 21mm aluminum alloy frame at the bottom. Three on the sides. The through-hole mates with the through-hole on the side of the stainless steel casing. The stainless steel casing is 2000mm long and is secured with high-side screws for easy disassembly and replacement.

[0131] Experiments have shown that when the bottom of the cylinder contacts the surface of the stainless steel slide, the friction is reduced to 1.5 times that of a normal roller, but there is no problem of aluminum blocks getting stuck on the roller. Pushing is easier and more stable, and the bottom is more stable and durable when it breaks.

[0132] A guide plate 22 is designed in the middle of the slide rail, which mates with the crankcase through groove at the bottom of the cylinder block with a clearance of 2mm to ensure proper placement of the cylinder block by the robot arm. The guide plate 22 is 12mm high and 2000mm long, with mounting holes on its surface. It is fastened to the lower aluminum alloy profile and installed on the slide rail bracket to ensure proper cylinder block pushing. The surface is blackened to prevent corrosion.

[0133] To address abnormal situations, this invention includes a position occupancy switch for cylinder position 1, and also adds a start condition for confirming the robot's return position. The start condition is that the optical sensor detects the correct workpiece position, the position occupancy switch opens, a signal for the robot to return to its original position is issued, and the support device is activated; this prevents the robot from colliding with the pushing mechanism if it fails to return. A backup operation program is also designed to stop operation in case of a support mechanism malfunction, and the pushing mechanism automatically pushes the cylinder to position 3, reducing the downtime due to support malfunctions.

[0134] To prevent aluminum blocks from entering the gap between the slide rail and the push cylinder during cylinder pushing and causing jamming of the pushing mechanism, a protective side plate 23 (slide rail protective plate) was designed. Based on the actual gap width and slide rail height, it is designed as an irregularly shaped plate, installed on the side of the slide rail, and secured with countersunk screws. Its bottom fits snugly against the push slide rail, effectively eliminating the gap between the slide rail and the cylinder and preventing aluminum chips and blocks from scraping and jamming.

[0135] To keep the surface of the push cylinder clean, a dust removal brush 24 was designed. It consists of a regular brush and a bracket, and is installed under the push block 10. The brush bristles contact the surface of the push cylinder and can clean the surface aluminum shavings as the push cylinder moves.

[0136] Positioning mechanism 2 is used to fix the cylinder on the slide to assist the operation of the support mechanism.

[0137] After various design attempts, in order to eliminate the impact of aluminum shavings and liquid corrosion on the fixture and to achieve the function of positioning cylinder in a limited space, it was finally designed as a suspended type.

[0138] To ensure seamless switching between 2.5 and 2.0 cylinder blocks, this invention compares the dimensions of various parts of the two models and determines that the center between the 2-hole and 3-hole ports is the common center of both cylinder blocks, namely, cylinder center 28. This center coincides with the center dimensions of the two decompression passages. Therefore, the inner walls of the 2-hole and 3-hole ports can be selected as a universal reference, and the cylinder block can be positioned using a suspension system.

[0139] Based on the bore spacing of the 2.5 and 2.0 cylinder blocks, as well as the changes in cylinder block height, a stepped positioning gripper was designed. The smaller end positioning surface 39 of the step corresponds to the 2.0 model, and the larger end positioning surface 40 corresponds to the 2.5 model. When positioning the cylinder block, it can tightly fit against both sides of bores 2 and 3. The positioning gripper has two... The pin hole is inlaid with A bushing, into which a locating pin can be inserted to connect the connecting rod, is used for transmission. One at the rear end. The pin hole connects to the cam follower 43 and serves a guiding function. The two... The pin hole is a non-circular positioning gripper. Pin hole 41, irregularly shaped positioning claw Pin hole 42;

[0140] The entire positioning mechanism utilizes the principle of linkage transmission. A multi-link 31 is connected via a connector 30 at the lower end of the positioning cylinder, driving the stepped positioning gripper to perform an opening motion. When the positioning cylinder extends to its fixed point, the force between the connecting rod 31 and the positioning cylinder rod forms a 90° angle, achieving self-locking in the horizontal direction.

[0141] Simultaneously, the sides of the stepped positioning grippers on both the left and right sides (left 32 and right 33) contact the first limiting blocks 48 on both sides of the positioning guide plate 46. The force borne by the positioning grippers is transmitted to the entire cantilever frame through the positioning guide plate 46, making the positioned cylinder more stable. (At this time, the stepped positioning grippers first contact the limiting blocks on both sides of the guide plate, with an allowable gap of <0.2mm between them and the inner wall of the cylinder bore.)

[0142] When the pushing mechanism 1 pushes the cylinder, there will be a deviation in the pushing position between the 2.5 and 2.0 models, with a center position difference of about 17mm. Ordinary devices require the addition of adjustment blocks to the pushing mechanism to eliminate the difference before the positioning action is performed. This increases on-site operations and is prone to oversights and errors. This invention requires an adaptive positioning mechanism. When designing the positioning guide plate 46, a pair of custom guide grooves 47 are made at the top to ensure the position of the starting and ending points, with a custom arc in the middle stroke. Then, the cam follower devices at the rear end of the left and right stepped positioning grippers are respectively placed, so that they make curved movements within the custom guide grooves 47. When the cylinder pushing position deviates, the cylinder bore can be gripped within a certain range. The center of the positioning mechanism is fixed between the centers of the 2.5 and 2.0 models, and connected to the positioning frame through the frame positioning plate 45, which can reduce the cylinder position offset and reduce the difficulty of the positioning mechanism gripping the cylinder. Combined with the self-locking property of the double linkage structure, universal positioning for both models is achieved. It also enables seamless switching between the 2.5 and 2.0 models without the need to replace parts, increasing the fault tolerance.

[0143] Increasing the width of the guide plate at the break point by 1.4mm can reduce the swaying of the cylinder during positioning and increase the stability of the break operation.

[0144] The C-shaped positioning frame is connected to the ground using anchor feet, which places a significant load on the upper part, causing some swaying during positioning operations. To increase stability, a sliding support bracket can be used as an auxiliary support. Two auxiliary support rods are designed, one end connected to the upper crossbeam of the sliding support bracket, and the other end connected to the uprights on both sides of the positioning frame. Experiments have shown that the C-shaped positioning frame did not wobble during the support operation, improving both stability and durability.

[0145] In terms of safety, the positioning cylinder uses an SMC fully locking cylinder, model CLG1DN40-100-E, which automatically locks in all positions when air supply is cut off (spring locking type). When the fully locking cylinder reaches the stop position, an additional safety lock 34 is added to prevent accidental operation during maintenance. The side-mounted thin cylinder engages with the connector's locking hole, which is opened during positioning mechanism operation and normally locked.

[0146] The function of the support mechanism 3 is to support the decompression passage when the positioning mechanism fixes the cylinder.

[0147] Once the cylinder body is positioned, the telescopic cylinder (CDM3L32-100-M9BW) on the second support positioning plate 54 drives the first support positioning plate 55 to extend, and the left and right hydraulic cylinders extend simultaneously to support and break the cylinder. After the cylinder breaks the cylinder, the hydraulic cylinders return, and the telescopic cylinders return.

[0148] To ensure that the pressure relief channel does not fall and accumulate inside the equipment upon breakage, it can be easily removed by the operator and placed into a collection bin. The desired breakage result of this invention is breakage without falling off.

[0149] Based on the shape of the left and right pressure relief channels and the position of the tie rod 16 between the connecting cylinders, as well as the adjustable height of the support device and the interference problem of the pressure relief channel during the pushing process, the present invention sets the support point between the second and third tie rods from the top.

[0150] Based on the characteristics of stable hydraulic transmission and amplification, the required pressure for the pressure relief channel, and the limited space, a small hydraulic cylinder was selected. However, the top area of ​​the cylinder rod is too small, making slippage prone to occur at the contact point with the pressure relief channel. To prevent slippage, a non-circular support clamp was designed based on actual measurements and experiments. The non-circular support clamp is designed in two different shapes according to the actual contact surfaces of the left and right pressure relief channels, ensuring a 90% fit. A 3mm high barb is designed at the top to effectively prevent the contact point from dislodging. The central threaded hole connects to the hydraulic cylinder rod thread (m14×1.5), and an additional nut is added for double-nut fastening. During installation, it should be screwed directly to the bottom of the thread; shims should not be used to adjust the thickness to prevent deformation of the shim's inner hole, which could lead to an unstable installation and unstable support clamp.

[0151] The cylinder rod of a hydraulic cylinder can drive the irregularly shaped support claw to rotate, causing support failure. It is necessary to restrict it to one direction. This invention designs an anti-rotation device. The rear end of the support claw is designed with a pin hole to install the anti-rotation pin, and a set screw hole is made on the side. A positioning surface is machined on the surface of the anti-rotation pin. After being inserted into the pin hole of the support claw, it is fixed to the positioning surface with a set screw. An anti-rotation bracket is fabricated, with a mounting hole at the lower end for threaded connection to the first support positioning plate (55mm), and a pin hole at the upper end for clearance fit with the anti-rotation pin inserted into the support claw. This ensures that the anti-rotation device maintains the pin hole fit during the support operation, guaranteeing the orientation of the support claw.

[0152] After numerous trials and improvements, the optimal support distance of 478.5mm was found, allowing the four broken stress relief braces to be easily removed without falling off.

[0153] Because the lever arm of the support claw is relatively long and the radial force is large, the cylinder rod may fatigue and fracture during prolonged support operations. Therefore, a balancing force device was designed to reduce the radial shear force. Based on torque calculations, a C-type positioning plate was used in conjunction with an adjustable buffer. One end of the C-type positioning plate 83 is designed as a mounting plate with four... Four M6 screw holes are designed on the first support positioning plate 55 for bolt connection. Screw holes are designed on the other end of the C-shaped positioning plate for installing a buffer. The position of the buffer is adjusted to ensure that when the front end of the support claw contacts the pressure relief channel, the rear end simultaneously contacts the buffer, and both begin to apply force at the same time, thus achieving force balance. The buffer is adjusted to five positions based on the on-site support test.

[0154] Because the existing 380V hydraulic station is too large, and sharing a 380V power supply with the casting machine would affect the stability of the equipment, this invention selects a small 220V hydraulic station, which is fixed under the support column.

[0155] An adjustable air blowing device was also installed to replace the operator's task of cleaning the marking positions on the cylinder.

[0156] The cleaning mechanism 4 uses a robotic arm to remove the loosened pressure relief channel after it has broken, and then sends it into the recycling bin.

[0157] After the broken cylinder is pushed to position 3, the robotic arm takes a picture to sense its location, uses the gripper assembly to remove the loose pressure relief channel, and puts it into the recycling bin behind it.

[0158] Due to limited space, this invention selected the small XM7 robotic arm to ensure the cleaning work was completed while reducing the chance of interference with surrounding objects.

[0159] To ensure the accuracy of the robotic arm's gripping, the cylinder's position must first be stabilized to prevent erratic movement. This invention incorporates a check valve at the rear end of the trolley at the bottom of the cylinder. The device automatically locks when the trolley returns and automatically unlocks after the cleaning mechanism completes its operation.

[0160] To address the issue of bin placement, a designated placement area is designed, and limit switches and sensors are installed. When the bin is not in the designated area, the robotic arm automatically pauses operation. When the bin returns to its original position, manual confirmation via a button is required for automatic operation to resume.

[0161] In terms of electrical components, solenoid valves are used to control pneumatic parts, and PLCs are used to control the processing sequence.

[0162] The pneumatic components are installed at the lower end of the cantilever frame.

[0163] The electrical control box is installed on the upper part of the cantilever frame.

[0164] The operation control panel is located above the operator's start switch.

[0165] To prevent safety hazards from the actuating mechanism, an aluminum alloy outer frame protective cover is installed at position 2, and a light grating 96 is installed at the exit to prevent accidental operation. An additional protective cover is installed on the internal positioning mechanism to prevent accidental contact.
