Description

Technical Field

[0001] The invention relates to the technical field of automated production and processing, and in particular to an automatic assembly mechanism for a retaining spring. Background Art

[0002] At present, the automation and efficiency of material replenishment in many industries are generally lower than those in the process manufacturing field. Circlips are a type of fastener, which are installed in the shaft grooves or hole grooves of machines and equipment. They play the role of preventing the axial movement of parts on the shaft or hole, and are widely used in a large number of equipment. At present, due to the rising labor costs, more product production is forced to move towards automation and batch manufacturing. For more and more fully automatic precision industrial automation production lines, when assembling circlips automatically, the circlips are replenished in a single product-by-product manner, which seriously affects the beat and production capacity.

[0003] Therefore, the prior art has defects and needs to be improved. Summary of the invention

[0004] The purpose of the invention is to overcome the deficiencies of the prior art and provide an automatic assembling mechanism for a retaining spring.

[0005] The technical solution of the present invention is as follows: a spring automatic assembly mechanism is provided, comprising: a spring pressing device, a feeding mechanism arranged beside the spring pressing device, and a material picking robot arranged beside the spring pressing device and the feeding mechanism, the spring pressing device comprising: a base, a slide seat arranged on the base, a clamping assembly arranged on the slide seat, a linear motion module arranged beside the base, and a push block assembly arranged on the moving end of the linear motion module, the clamping assembly comprising: a slider connected to the push block assembly, a slot block connected to the slider, and a plurality of springs arranged between the slider and the slot block.

[0006] Furthermore, the clamping assembly and the linear motion module are respectively connected to two ends of the push block assembly, and the main parts of the clamping assembly and the linear motion module are arranged on the same side of the push block assembly.

[0007] Furthermore, a push rod is provided on the sliding block, and a front end of the push rod is in movably contact with the slot block.

[0008] Furthermore, the slide seat is provided with a guide rail, and the slider and the slot block are respectively mounted on the guide rail.

[0009] Furthermore, the connecting surface between the sliding block and the push block assembly is provided with a plurality of adjusting threaded holes, and the push block assembly is provided with a plurality of adjusting screws corresponding to the adjusting threaded holes, and the adjusting screws are screwed into the adjusting threaded holes.

[0010] Furthermore, a product placement seat is provided beside the clamping spring pressing device, and the product placement seat is placed at the front end of the slot block, and the slot block is in active contact with the product placement seat.

[0011] Furthermore, a retaining spring placement groove is provided at the front end of the slot block.

[0012] Furthermore, a limit pin is provided at one end of the slide seat close to the slot block corresponding to the slot block, and the limit pins are symmetrically arranged on both sides of the slot block, and the limit pins are in active contact with the slot block.

[0013] Furthermore, the feeding mechanism includes a vibration plate and a feeding plate which are connected to each other.

[0014] By adopting the above scheme, the present invention drives the push block assembly to move the clamping assembly through the linear motion module. In the process of the push block assembly pushing the clamping assembly to move, the front end of the slot block will contact the product to be loaded with the retaining spring. At the same time, the slider continues to move toward the slot block, so that the spring between the slider and the slot block is squeezed, causing the spring elastic force to gradually increase, thereby increasing the force acting on the retaining spring, and then ensuring that the retaining spring is pushed into the corresponding retaining spring groove on the product, thereby realizing the rapid assembly of the retaining spring, effectively improving the efficiency of the retaining spring assembly, and having a simple structure, low production and maintenance costs, while reducing manual participation and improving the degree of automation.

[0017] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] See also Figure 1 , Figure 2The present invention provides an automatic assembly mechanism for a retaining spring, comprising: a retaining spring pressing device 1, a feeding mechanism 2 arranged beside the retaining spring pressing device 1, and a material taking manipulator 3 arranged beside the retaining spring pressing device 1 and the feeding mechanism 2. The retaining spring pressing device 1 comprises: a base 11, a slide seat 12 arranged on the base 11, a clamping assembly 13 arranged on the slide seat 12, a linear motion module 14 arranged beside the base 11, and a push block assembly 15 arranged on the moving end of the linear motion module 14. The clamping assembly 13 comprises: a slider 131 connected to the push block assembly 15, a slot block 132 connected to the slider 131, and a plurality of springs 133 arranged between the slider 131 and the slot block 132. During operation, the retaining spring to be installed is provided by the feeding mechanism 2, and the retaining spring is picked up by the material taking manipulator 3 and then placed at the front end of the slot block 132. The linear motion module 14 is started, thereby driving the clamping assembly 13 to move through the push block assembly 15. When the push block assembly 15 pushes the clamping assembly 13 to move, the front end of the slot block 132 will contact the product to be loaded with the retaining spring. At the same time, the slider 131 continues to move toward the slot block 132, so that the spring 133 between the slider 131 and the slot block 132 is squeezed. Under the action of the elastic force of the spring 133, the elastic potential energy generated by the compression spring 133 is converted into kinetic energy, thereby forming a force applied to the slot block 132, thereby increasing the force acting on the retaining spring, thereby ensuring that the retaining spring is pushed into the corresponding retaining spring slot on the product, and realizing the rapid assembly of the retaining spring.

[0019] In some embodiments, the clamping assembly 13 and the linear motion module 14 are respectively connected to the two ends of the push block assembly 15, and the main parts of the clamping assembly 13 and the linear motion module 14 are arranged on the same side of the push block assembly 15. By arranging the main part of the linear motion module 14 and the clamping assembly 13 on the same side of the push block assembly 15, the floor space occupied by the overall structure is effectively reduced, making the overall structure design more compact.

[0020] In some embodiments, a push rod 134 is provided on the slider 131, and the front end of the push rod 134 is in active contact with the slot block 132. The slider 131 pushes the slot block 132 through the push rod 134, so that in the process of the slot block 132 approaching the product, the push rod 134 pushes the slot block 132 to achieve rapid movement of the slot block 132, thereby avoiding the situation that the slot block 132 is pushed forward and backward during the movement due to the rapid conversion of the spring 133 between the compression and rebound states, thereby causing the retaining spring to fall from the front end of the slot block 132, or the retaining spring is offset due to the movement, which affects the accuracy of the retaining spring being installed in the product.

[0021] In some embodiments, the slide seat 12 is provided with a guide rail 121, and the slider 131 and the slot block 132 are respectively mounted on the guide rail 121. The guide rail 121 provides guidance for the movement of the slider 131 and the slot block 132, thereby ensuring the accuracy of the movement path of the slider 131 and the slot block 132, and avoiding the situation where the clamping spring and the product are offset and affect the assembly effect. At the same time, the guide rail 121 can reduce the friction between the slider 131 and the slot block 132 and the slide seat 12, ensuring that the slider 131 and the slot block 132 move smoothly.

[0022] In some embodiments, the connection surface between the slider 131 and the push block assembly 15 is provided with a plurality of adjustment threaded holes, and the push block assembly 15 is provided with a plurality of adjustment screws 151 corresponding to the adjustment threaded holes, and the adjustment screws 151 are screwed into the adjustment threaded holes. By changing the depth position of the adjustment screws 151 screwed into the adjustment threaded holes, the relative distance between the push block assembly 15 and the slider 131 is changed, so that when the linear motion module 14 drives the push block assembly 15 and then drives the slider 131 to move, the overall moving distance of the slot block 132 is adjusted to meet the assembly requirements of the retaining springs in products of different specifications. At the same time, adjusting the relative distance between the push block assembly 15 and the slider 131 will change the thrust applied by the spring 133 to the slot block 132, thereby meeting the thrust requirements of different retaining springs during the assembly process.

[0023] In some embodiments, a product placement seat 4 is provided beside the clamp spring pressing device 1, and the product placement seat 4 is placed at the front end of the slot block 132, and the slot block 132 is in active contact with the product placement seat 4. The product placement seat 4 provides fixation and positioning for the product, thereby ensuring that the product will not be offset or shifted during the assembly process of the clamp spring, thereby ensuring the accuracy of the assembly of the clamp spring.

[0024] In some embodiments, a retaining ring placement groove is provided at the front end of the groove block 132, so that after the retaining ring is picked up from the feeding mechanism 2 by the material picking robot 3, the retaining ring is placed on the retaining ring placement groove, thereby providing a limit for the retaining ring and ensuring the accuracy of the retaining ring assembly process.

[0025] In some embodiments, a limit pin 122 is provided at one end of the slide seat 12 close to the slot block 132 corresponding to the slot block 132 , and the limit pins 122 are symmetrically arranged on both sides of the slot block 132 , and the limit pins 122 are in active contact with the slot block 132 .

[0026] In some embodiments, the feeding mechanism 2 includes a vibration plate 21 and a feeding plate 22 connected to each other. Before assembly, the clip is poured into the feeding plate 22. When the vibration plate 21 is started, the clip slowly slides into the vibration plate 21 with the vibration, and the direction is unified under the vibration of the vibration plate 21, which is convenient for the material picking robot 3 to pick up, and ensures that the direction of the clip is unified when the material picking robot 3 places the clip on the slot block 132 after picking up the clip each time, so as to meet the direction requirements for installing the clip on the product.

[0027] To summarize, the present invention drives the push block assembly to move the clamping assembly through a linear motion module. In the process of the push block assembly pushing the clamping assembly to move, the front end of the slot block will contact the product to be loaded with the retaining spring. At the same time, the slider continues to move toward the slot block, so that the spring between the slider and the slot block is squeezed, causing the spring elastic force to gradually increase, thereby increasing the force acting on the retaining spring, thereby ensuring that the retaining spring is pushed into the corresponding retaining spring groove on the product, realizing rapid assembly of the retaining spring, and effectively improving the efficiency of retaining spring assembly. It has a simple structure, low production and maintenance costs, and reduces manual participation, thereby improving the degree of automation.
