Description

Technical Field

[0001] This utility model belongs to the field of industrial robot technology, and more specifically, it relates to a cylinder liner die-casting robot that facilitates material feeding. Background Technology

[0002] Cylinder liner die-casting robots typically employ a six-axis or multi-axis linkage design, possessing 360° rotation and flexible spatial movement capabilities. This facilitates access to complex positions at the die-casting machine's feed inlet, ensuring accurate alignment of the cylinder liner blank or mold components with the feed inlet and avoiding positional deviations during manual operation. Existing cylinder liner die-casting robots that facilitate feeding generally consist of a robotic arm, a power unit, a vision perception unit, and an end effector.

[0003] Existing application number: CN201621301822.4, this utility model discloses a multi-axis industrial robot, including a base fixed to an external injection molding machine and a robotic arm connected to the base. The robotic arm includes a first axis arm and a second axis arm hinged to each other. The first axis arm is movably connected to the base, and the rotation center axis of the second axis arm is horizontally set and moves laterally towards the base in the direction of rotation. Compared with the prior art, the rotation center axis of the second axis arm of this utility model is moved laterally towards the base in the direction of rotation. In actual use, this avoids interference between the movement paths of the base and the robotic arm. The robotic arm can smoothly grasp products in front of, directly below, and behind the base, thus enabling it to grasp or process products over a wide range. It is widely applicable to injection molding, embedding, assembling, deburring, and sprue trimming in injection molding machines.

[0004] Based on the above, the joints of the robotic arm need to be regularly injected with lubricating oil to avoid excessive wear. Traditional oiling methods often result in excessive oiling due to the conservative operation of manual "better too much than too little". This causes the grease to be thrown off by centrifugal force during joint movement, which may not only contaminate the joints and die-casting molds, but also attract aluminum dust to form high-hardness abrasive particles, leading to increased wear of parts and affecting their use. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a cylinder liner die-casting robot that facilitates material feeding. This solves the problem that existing robotic arm joints require regular lubrication to prevent excessive wear. Traditional lubrication methods often involve excessive lubrication due to the conservative "better too much than too little" approach. This causes the grease to be thrown off during joint movement due to centrifugal force, potentially contaminating the joints and die-casting mold. It can also attract aluminum dust, forming high-hardness abrasive particles, leading to increased wear on components and affecting their usability.

[0006] The purpose and effect of this utility model, which provides a convenient cylinder liner die-casting robot, are achieved through the following specific technical means:

[0007] A cylinder liner die-casting robot with easy feeding includes a mounting base, a base, an operating arm, a storage box, a connecting shaft, a fixing box, an automatic oil supply component, and an auxiliary installation component. The base is fixedly connected to the mounting base. The operating arm is hinged to the top of the base. The storage box is fixedly connected to the front of the base. The connecting shaft is coaxially fixedly connected to the front end of the shaft at the hinge between the operating arm and the base. The fixing box is fixedly connected inside the mounting base. The automatic oil supply component is disposed inside the storage box. The auxiliary installation component is disposed inside the mounting base.

[0008] Furthermore, the automatic oil supply assembly includes a drive ratchet and a drive pawl; the drive ratchet is coaxially and fixedly connected to the front of the connecting shaft; the drive pawl is rotatably connected inside the storage box, and the drive pawl meshes with the drive ratchet.

[0009] Furthermore, the automatic oil supply assembly also includes: a reciprocating screw and a movable push plate; the reciprocating screw is coaxially fixedly connected to the front end of the transmission pawl; the movable push plate is slidably connected inside the storage box, and the movable push plate is threadedly connected to the reciprocating screw.

[0010] Furthermore, the automatic oil supply assembly also includes: a sealing cap and an oil supply pipeline; the sealing cap is threadedly connected to the top of the storage box; the two ends of the oil supply pipeline on the left side are fixedly connected to the inside of the storage box, and one end of the oil supply pipeline on the right side is fixedly connected to the inside of the base.

[0011] Furthermore, the auxiliary installation components include: a sliding plate, a pull column, and a positioning column; the sliding plate is slidably connected inside the fixing box; the left end of the pull column is fixedly connected to the right side of the sliding plate, and the right end of the pull column is slidably connected to the right end of the fixing box; the positioning column is fixedly connected to the left side of the sliding plate, and the sliding plate is slidably connected to the left end of the fixing box.

[0012] Furthermore, the auxiliary installation component also includes: a positioning spring and a positioning box; the left end of the positioning spring is fixedly connected to the right side of the sliding plate, and the right end of the positioning spring is fixedly connected to the inside of the fixing box; the positioning box is fixedly connected to the bottom right side of the base.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, by setting up a storage box, a large amount of lubricating grease can be injected into it in advance. During the downward swing of the operating arm, the moving push plate will slide forward or backward through the hinge shaft at the joint, so that an appropriate amount of grease is automatically injected into the hinge shaft, ensuring that the joint is always in a state of adequate grease lubrication.

[0015] Secondly, when inspecting the robotic arm, the positioning box prevents the robotic arm from tipping over due to the worker not holding it firmly after the bolts are removed. During installation, the positioning box is inserted into the mounting base to temporarily fix the robotic arm so that the bolts can be tightened later.

[0016] This utility model, through the linkage design of the storage box and the moving push plate, allows the robotic arm to automatically inject an appropriate amount of grease into the joint hinge shaft during swinging, achieving continuous lubrication. The positioning box can prevent the robotic arm from tipping over after the bolts are removed during maintenance, and can also provide temporary fixation during installation, making it easy to tighten the bolts. The overall design not only reduces equipment wear and maintenance costs, but also ensures the personal safety of workers during maintenance. Attached Figure Description

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] Example 1:

[0028] As attached Figure 1 To be continued Figure 7 As shown:

[0029] This utility model provides a cylinder liner die-casting robot that facilitates material feeding, including a mounting base 1, a base 2, an operating arm 3, a storage box 4, a connecting shaft 5, a fixing box 9, and an automatic oil supply assembly; the base 2 is fixedly connected to the mounting base 1; the operating arm 3 is hinged to the top of the base 2; the storage box 4 is fixedly connected to the front of the base 2; the connecting shaft 5 is coaxially fixedly connected to the front end of the shaft at the hinge between the operating arm 3 and the base 2; the fixing box 9 is fixedly connected inside the mounting base 1; and the automatic oil supply assembly is disposed inside the storage box 4.

[0030] The automatic oil supply assembly includes a transmission ratchet 501 and a transmission pawl 601. The transmission ratchet 501 is coaxially fixedly connected to the front of the connecting shaft 5. The transmission pawl 601 is rotatably connected inside the storage box 4, and the transmission pawl 601 meshes with the transmission ratchet 501.

[0031] The automatic oil supply assembly also includes: a reciprocating screw 6 and a movable push plate 7; the reciprocating screw 6 is coaxially fixedly connected to the front end of the transmission pawl 601; the movable push plate 7 is slidably connected inside the storage box 4, and the movable push plate 7 is threadedly connected to the reciprocating screw 6.

[0032] The automatic oil supply assembly also includes: a sealing cap 401 and an oil supply line 8; the sealing cap 401 is threadedly connected to the top of the storage box 4; the two ends of the left side of the oil supply line 8 are fixedly connected to the inside of the storage box 4, and the right end of the oil supply line 8 is fixedly connected to the inside of the base 2.

[0033] The specific usage and function of this embodiment: Upon first use, rotate the sealing cover 401 to open it, then inject lubricating oil into the storage box 4. During the cylinder liner feeding and unloading operation, whenever the operating arm 3 swings downward, the connecting shaft 5 drives the transmission ratchet 501 to rotate. The transmission ratchet 501, together with the transmission pawl 601, drives the reciprocating screw 6 to rotate through the ratchet and pawl transmission mechanism. The reciprocating screw 6, together with the moving push plate 7, drives the moving push plate 7 to slide forward a portion through the threaded transmission mechanism, thereby pushing the lubricating oil in the storage box 4 into the oil supply line 8. The right end of the oil supply line 8 is connected to the hinge shaft of the base 2 and the operating arm 3, thereby injecting lubricating oil into the hinge shaft, which is then used in the ratchet and pawl transmission. Under the unidirectional transmission characteristic of the mechanism, the reciprocating screw 6 can only rotate in one direction, thus avoiding the sliding of the moving push plate 7 back and forth. Then, the threaded transmission mechanism formed by the reciprocating screw 6 and the moving push plate 7 will cause the moving push plate 7 to move to the front end and then automatically return. The time when the moving push plate 7 moves to the front end can be inferred based on the working time of the operating arm 3 or the number of cylinder liners processed, so that lubricating oil can be added to the storage box 4 again in time by opening the sealing cover 401. After the lubrication is completed, when the moving push plate 7 moves to the front end and automatically returns to the rear, the automatic lubrication operation can continue. Similarly, automatic oil supply components can be set at each joint of the operating arm 3 to ensure smooth operation of each part.

[0034] Example 2:

[0035] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 7 As shown, it also includes an auxiliary installation component, which is located inside the mounting base 1.

[0036] The auxiliary installation components include: a sliding plate 10, a pull column 1001, and a positioning column 1002; the sliding plate 10 is slidably connected inside the fixed box 9; the left end of the pull column 1001 is fixedly connected to the right side of the sliding plate 10, and the right end of the pull column 1001 is slidably connected to the right end of the fixed box 9; the positioning column 1002 is fixedly connected to the left side of the sliding plate 10, and the sliding plate 10 is slidably connected to the left end of the fixed box 9.

[0037] The auxiliary installation components also include: a positioning spring 1003 and a positioning box 11; the left end of the positioning spring 1003 is fixedly connected to the right side of the sliding plate 10, and the right end of the positioning spring 1003 is fixedly connected to the inside of the fixing box 9; the positioning box 11 is fixedly connected to the bottom right side of the base 2.

[0038] The specific usage and function of this embodiment are as follows: When the overall structure above the mounting base 1 needs to be disassembled for maintenance, first remove the bolts used to fix the base 2 and the mounting base 1, then pull the pulling column 1001 to the right, causing the sliding plate 10 and the positioning column 1002 to move to the right simultaneously. The positioning column 1002 disengages from the positioning box 11. Then, move the overall structure above the mounting base 1 upward to remove it for easy maintenance. The positioning box 11 avoids the risk of the overall structure above the mounting base 1 tipping over due to operator carelessness after the bolts used to fix the base 2 and the mounting base 1 are removed. When reinstalling, first pull the pulling column 1001 to the right, then insert the positioning box 11 into the mounting base 1, and then release the pulling column 1001. Under the rebound action of the positioning spring 1003, the positioning column 1002 inserts into the positioning box 11, which can temporarily fix the overall structure above the mounting base 1, making it easier to tighten the bolts later.
