Description

Technical Field

[0001] This invention relates to the field of spring mounting technology, and in particular to a spring mounting device. Background Technology

[0002] With the progress of industrialization and the continuous improvement of productivity, in order to improve production efficiency and ensure product quality, producers are gradually paying attention to the degree of automation in the production process, minimizing the intensity and complexity of manual operation, and replacing manual labor with automated equipment.

[0003] Existing automated or semi-automatic spring installation methods in the industry are generally simple and easy. For example, the upper and lower ends of the spring are separate, not fixed in size, and can be installed piece by piece. Alternatively, after installation, no other guide components need to be installed in the center of the spring, and there are no requirements regarding the spring's posture (e.g., bent position). Current on-site methods are manual, using tooling and requiring two people. The operation consists of four steps: disassembling the connecting rod, installing the guide tooling, installing the spring, and rotating the product. These actions are repeated six times. The specific steps are as follows:

[0004] (1) The product is laid flat on the ground by a crane, and one person removes one connecting rod;

[0005] (2) One person installs the guide head at the head of the connecting rod;

[0006] (3) One person holds the tail wing of the connecting rod with one hand and pushes the connecting rod with the other hand, while the other person installs the spring with all their might. The two people work together to install the spring while pushing the connecting rod.

[0007] (4) Two people lift the product and flip it to the next angle. Then, turn the tail fin upwards and repeat steps 1-3. Flip it 6 times to complete the installation.

[0008] The applicant has found that the prior art has at least the following technical problems: (1) The degree of automation is low. The disassembly and assembly of connecting rods, the installation of springs, and the hoisting and handling of products all require two people to complete, which is inefficient and labor-intensive.

[0009] (2) Manual operation is dangerous. When installing springs manually, the springs have a large elastic force, and there is both pressure and torque, which can easily cause the spring to jump out and hurt people.

[0010] (3) The manual operation is very demanding, the spring force is large, two people are required to cooperate, and the physical strength of the operators is high.

[0011] (4) It consumes a lot of tooling. Because the spring is compressed by length and angle during installation, the spring will bend after installation. The existing method requires manual installation of guide cones to guide the spring when inserting the rod. Therefore, a lot of tooling is required during the assembly process.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0045] like Figure 1-9 As shown, some embodiments of this application provide a spring mounting device, including a spring feeding turntable 1, a handling and mounting device 2, and a mounting platform 3;

[0046] When product 4 is placed on the mounting platform 3, the handling and installation equipment 2 can install the spring on the spring loading turntable 1 onto product 4;

[0047] The handling and installation equipment 2 is capable of detachably replacing the clamps holding the product 4 and the clamps holding the springs.

[0048] In practice, the spring feeding turntable 1 serves as the feeding mechanism for the spring 13. When the product 4 is not on the mounting machine 3, the handling and installation equipment 2 can be replaced with a clamp for holding the product 4. The robot clamps the product 4 and places it on the mounting machine 3. When the product 4 is placed on the mounting machine 3, the handling and installation equipment 2 can be replaced with a clamp for holding the spring 13. The handling and installation equipment 2 can take the spring 13 from the spring feeding turntable 1 and then install the spring 13 on the product 4, thereby realizing the installation of the spring 13 by machine equipment instead of manual labor.

[0049] In practical implementation, this application provides a fully automated spring feeding and installation device and method. Compared to traditional manual installation, it changes the original work that required two people to complete, avoiding the dangers of manual spring installation. The equipment replaces manual labor, reducing the intensity of manual operation. Since springs require at least 140N of pressure to compress, high demands are placed on the worker's physical fitness and operational skills. Using equipment to replace frequent manual operations reduces intensity and increases efficiency. No auxiliary tooling is needed; the equipment automatically performs guiding and docking functions, saving production materials and time. By simulating manual operation through machine equipment and using a multi-mechanism linkage, it achieves automatic installation of springs with fixed slot sizes. Multiple guide columns achieve automatic spring feeding and positioning, solving the problem of spring sticking during feeding, resulting in lower cost and a simpler structure.

[0050] In some embodiments, the spring feeding turntable 1 includes a turntable 11, a guide column 12, and a spring 13;

[0051] Multiple sets of guide posts 12 are provided, and the multiple sets of guide posts 12 are distributed along the circumferential direction of the turntable 11. A spring 13 is correspondingly provided on each guide post 12.

[0052] In practice, the turntable 11 includes a fixed base at the bottom and an upper turntable that can rotate. The turntable is driven by a motor and a cam divider to rotate at a certain angle so that the spring 13 on the turntable reaches the position that the robot 21 can grasp.

[0053] In some embodiments, each set of guide posts 12 includes at least one central post 121 and two positioning posts 122, with the spring 13 sleeved on the central post 121 and the end of the spring 13 extending between the two positioning posts 122.

[0054] In practice, the guide post 12 consists of three parts: a central post 121 (the central guide post of the spring), two positioning posts 122 (the angle positioning posts on both sides of the spring), and springs 13 pass through the central guide post in sequence and are stacked from bottom to top. Because springs 13 have both compression and torque, the angle of springs 13 needs to be controlled. Therefore, the guide posts on both sides define the feeding angle of the springs. In addition, this prevents the possibility of spring rotation and also prevents the phenomenon of stacked connection between springs.

[0055] In some embodiments, the handling and installation equipment 2 includes a robot 21, an installation fixture 22, a handling fixture 23, and a fixture storage platform 24;

[0056] The robot 21 is a six-axis linkage robot. The fixture storage platform 24 is located on one side of the robot 21. The mounting fixture 22 and the handling fixture 23 can be placed on the fixture storage platform 24. The mounting fixture 22 and the handling fixture 23 are both connected to the robot 21 through quick-change chucks.

[0057] In specific implementation, the robot 21 is a six-axis linkage robot, which is existing technology and will not be described in detail here. The mounting fixture 22 and the handling fixture 23 can be mounted on the robot 21 through a quick-change chuck. During use, one of the fixtures is mounted on the robot 21, and the other unused fixture is placed on the fixture storage table 24. The handling fixture 23 is used to clamp and handle the product 4. The handling fixture 23 is composed of profile welding and assembly, and adopts the form of cylinder guide rail. It can clamp the outer ring of the product 4 on both sides to realize loading and unloading. The mounting fixture 22 is used to clamp the spring 13.

[0058] In some embodiments, the mounting fixture 22 includes a mounting part 221, a spring clamping mechanism 222, a pressing mechanism 224, a lower pushing and displacing mechanism 225, and a lower pushing mechanism 223;

[0059] The spring clamping mechanism 222, the pressing mechanism 224, and the lower pushing and shifting mechanism 225 are all disposed on the mounting part 221. The spring clamping mechanism 222 is disposed on one side of the mounting part 221. One end of the lower pushing and shifting mechanism 225 is disposed on the side of the mounting part 221 away from the mounting part 221. The other end of the lower pushing and shifting mechanism 225 is connected to the lower pushing mechanism 223. The pressing mechanism 224 is disposed between the spring clamping mechanism 222 and the lower pushing and shifting mechanism 225. The movement direction of the pressing mechanism 224 is perpendicular to the movement direction of the lower pushing mechanism 223.

[0060] In practice, robot 21 carries installation fixture 22 to grasp and install spring 13. Installation fixture 22 consists of multiple sets of cylinders to simulate the process of manually installing springs. Spring clamping mechanism 222 includes pneumatic grippers that clamp and pick up spring 13 from spring loading turntable 1 and transfer it to the installation position of product 4, so that one end of spring 13 is aligned with the installation end face. The lower push-in displacement mechanism 225 under the fixture extends, so that the lower push-in mechanism 223 abuts against the free end of spring 13, pushing the spring to the other end face of the installation position. At this time, the pressing mechanism 224 can immediately press spring 13 into the installation groove of product 4, completing the installation of spring 13.

[0061] In some embodiments, the installation platform 3 includes an equipment base 31, a lifting slide 32, a connecting rod pulling mechanism 33, a connecting rod lifting mechanism 34, a servo turntable 35, a tail wing fixing mechanism 36, and a product platform 37.

[0062] One side of the equipment base 31 is provided with a machine platform column 311, and the other side of the equipment base 31 is provided with a product platform 37. The lifting slide 32 is slidably disposed on the machine platform column 311 and can slide along the axis of the machine platform column 311. The connecting rod pulling mechanism 33 is disposed on the lifting slide 32. The product platform 37 is provided with a servo turntable 35, and the product 4 can be placed on the servo turntable 35. The connecting rod lifting mechanism 34 is disposed on the side of the equipment base 31 near the product platform 37, and the movement direction of the connecting rod lifting mechanism 34 is the same as that of the connecting rod pulling mechanism 33.

[0063] In practical implementation, the equipment base 31 (equipment platform) is assembled from welded steel pipes and steel plates. The lifting slide 32 slides on the machine base column 311 and is driven by a servo screw 312. The lower part of the lifting slide 32 is designed with a follow-up turntable composed of bearings. When the lifting slide 32 rises, space is left on the upper end face of the product 4 for loading and unloading. When the lifting slide 32 falls, the follow-up turntable is positioned with the upper end face of the product 4, thus determining the position of the product's central axis and avoiding positional movement during installation. The product base 37 is equipped with a servo turntable 35, which is a servo motor driven turntable structure to center the lower end face of the product and can be adjusted to 6 angles for easy installation of springs.

[0064] In some embodiments, the connecting rod pulling mechanism 33 includes a first servo lifting slide 331, a first slide displacement cylinder 332, and a three-finger gripper mechanism 333.

[0065] The first slide displacement cylinder 332 is connected to the first servo lifting slide 331. The first slide displacement cylinder 332 is disposed on the lifting slide 32. The first servo lifting slide 331 passes through the lifting slide 32 and extends toward the equipment base 31. A three-finger gripper mechanism 333 is provided at one end of the first servo lifting slide 331 that passes through the lifting slide 32.

[0066] The connecting rod lifting mechanism 34 includes a second servo lifting slide 341, a cylinder guide rod mechanism 342, and a second slide displacement cylinder 343.

[0067] The second slide displacement cylinder 343 is connected to the second servo lifting slide 341. The cylinder guide rod mechanism 342 is disposed on one side of the second servo lifting slide 341. The axis of the second servo lifting slide 341 is parallel to the axis of the cylinder guide rod mechanism 342. The axis of the cylinder guide rod mechanism 342 is perpendicular to the end face of the equipment base 31.

[0068] In practical implementation, the connecting rod pulling mechanism 33 consists of a first servo lifting slide 331, a first slide displacement cylinder 332, and a three-finger gripper mechanism 333.

[0069] The connecting rod lifting mechanism 34 consists of a second servo lifting slide 341, a cylinder guide rod mechanism 342, and a second slide displacement cylinder 343. The connecting rod pulling mechanism 33 and the connecting rod lifting mechanism 34 work together in operation, mainly to complete the functions of disassembling and retracting the connecting rod 41 and inserting the spring 13. In practice, the three-finger gripper mechanism 333 in the connecting rod pulling mechanism 33 grips the upper head of the connecting rod 41, the first servo lifting slide 331 rises, and the connecting rod 41 disengages from the product tail wing hole. After the robot 21 installs the spring 13, the second servo lifting slide 341 in the connecting rod lifting mechanism 34 rises, and the guide rod of the cylinder guide rod mechanism 342 pushes out, making the head of the guide rod conical and passing through the inner hole of the spring 13, guiding the spring 13 to a vertical position. After the guide cone head contacts the lower part of the connecting rod 41, the second servo lifting slide 341 in the connecting rod lifting mechanism 34 continues to rise, the guide rod cylinder retracts, and a blind hole appears at the upper end of the rod of the lifting mechanism. The blind hole is sleeved on the threaded surface of the connecting rod. The outer diameter of the rod of the connecting rod lifting mechanism 34 is consistent with the outer diameter of the connecting rod 41 of the product 4. At this time, the two mechanisms descend simultaneously, allowing the connecting rod 41 to pass normally through the inner diameter of the spring 13. This process completes one installation of the spring 13 and the connecting rod 41. When installing the second spring, the connecting rod lifting mechanism 34 first descends. After the robot 21 installs the spring 13, the connecting rod lifting mechanism 34 rises again to contact the lower part of the connecting rod 41. This process is repeated to complete the installation of the second and third springs 13. The installation of the springs 13 at the six angles follows the same process. The slide table positioning cylinder is used to automatically switch between two different sizes of machines when their positions are different.

[0070] In some embodiments, a tail wing fixing mechanism 36 is provided on one side of the bottom of the lifting slide 32. The tail wing fixing mechanism includes a pneumatic lifting platform 361 and a clamping cylinder 362. The pneumatic lifting platform 361 is disposed on the lifting slide 32, and the clamping cylinder 362 is disposed on the pneumatic lifting platform 361.

[0071] In practical implementation, the lifting slide 32 is designed with a tail wing fixing mechanism 36 on its side. Its function is to ensure that when the connecting rod is disengaged from the tail wing and the central cylinder, the tail wing can maintain a relative position with the central cylinder. This mechanism consists of a pneumatic lifting platform 361 and a clamping cylinder 362, both of which are pneumatic transmission components. After the slide descends, the clamping cylinder 362 can clamp and fix the tail wing. After the clamping cylinder 362 is released and the slide rises, this mechanism avoids the rotation space of the tail wing of product 4, thus preventing interference when product 4 rotates on the servo turntable 35.
