Description

Technical field:

[0001] The utility model relates to the technical field of automation, in particular to a C-buckle automatic assembly mechanism. Background technology:

[0002] With the continuous development and progress of production technology, it is an inevitable trend for automated equipment to replace traditional manual operations. Automated equipment with simple structure and superior functions has greatly improved production efficiency and solved problems such as manual inconvenience, low efficiency, and low assembly quality in the production process.

[0003] The traditional C-clip (100 is a type of circlip) is usually installed manually, and the process generally requires manually holding the workpiece to install the circlip. This is not only inefficient, but also easy to break due to the small size of the circlip, which ultimately increases the cost of circlip installation and increases the scrap rate.

[0004] The Chinese utility model with authorization announcement number CN220863209U discloses an automatic retaining spring installation device, which includes an integral bracket, a retaining spring pressing cylinder, a retaining spring pressing block, a workpiece positioning block, a workpiece positioning seat, and a retaining spring pushing assembly; the cylinder body of the retaining spring pressing cylinder is fixedly connected to the integral bracket, the free end of the piston rod of the retaining spring pressing cylinder is connected to an extension rod, the end of the extension rod is fixedly connected to the retaining spring pressing block, the workpiece positioning seat is fixedly connected to the bottom of the integral bracket, the workpiece is arranged on the workpiece positioning seat, the workpiece is provided with a workpiece positioning block, and the retaining spring pushing assembly is fixedly connected to the integral bracket; the retaining spring pushing assembly includes a pushing bracket, a pushing cylinder, a bottom plate, a slider mounting plate, a vertical plate and a vertical rod, the bottom plate is installed on the pushing bracket, the vertical plate is fixedly connected to the vertical rod, and the retaining spring assembly is detachably connected to the vertical plate. During use, the workpiece is positioned on the workpiece positioning seat, the stop pin on the storage barrel is pulled out, and the retaining ring slides down under gravity to the lower end of the vertical rod. The pushing cylinder extends, and the free end of the piston rod drives the slider mounting plate to slide on the bottom plate, pushing a retaining ring onto the workpiece positioning block. The retaining ring pressing cylinder is activated, and the free end of the piston rod drives the retaining ring pressing block downward, pushing the retaining ring into the retaining ring mounting groove of the workpiece, completing the retaining ring installation. The above-mentioned automatic retaining ring installation device solves the problems of low efficiency and difficult to control precision when installing retaining rings manually.

[0005] However, the above-mentioned automatic retaining spring installation device still has the following problems:

[0006] The end of the base plate is flat, so that the end of the base plate cannot directly connect with the workpiece positioning block. A gap is formed between them. As a result, after the retaining spring is pushed out of the end of the base plate, the retaining spring is partially suspended, resulting in the retaining spring not being accurately and stably pushed onto the workpiece positioning block. There is a risk of the retaining spring falling, affecting the efficiency of retaining spring installation. In addition, the retaining spring is pushed by the slider mounting plate and slides, and when sliding, it rubs against the slot body, causing the retaining spring to rotate, resulting in a change in the direction of the retaining spring, which in turn affects the subsequent assembly. In addition, a retaining spring pressing cylinder is required to cooperate with the retaining spring pressing block to push the retaining spring on the workpiece positioning block into the retaining spring installation slot of the workpiece, which makes the structure more complicated and the cost relatively high.

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] See Figure 1-6 As shown, a C-buckle automatic assembly mechanism includes a base plate 1, a push plate 3 slidably installed in the slide groove 11 of the base plate 1, a storage rack 2 installed on the base plate 1 and used to store C-buckles and transport C-buckles 100 to the push plate 3, and a power module 4 for driving the push plate 3 to slide in the slide groove 11. When in use, the storage rack 2 transports the bottom C-buckle 100 to the push plate 3, and the power module 4 drives the push plate 3 to slide in the slide groove 11, thereby pushing the C-buckle 100 out and loading it into the annular groove 201 of the workpiece 200, so as to achieve the purpose of automatically assembling the C-buckle.

[0028] A first avoidance groove 31 for accommodating the workpiece 200 is provided on the outer side of the front end of the push plate 3, and a supporting groove 32 for supporting the C buckle 100 is opened downward along the upper surface of the front end of the push plate 3. The supporting groove 32 is located on the outer side of the opening on the first avoidance groove 31. When the C buckle 100 falls into the supporting groove 32, the edge of the inner hole of the C buckle 100 protrudes in the first avoidance groove 31. In specific use, after the storage rack 2 transports the bottom C buckle 100 to the supporting groove 32 of the push plate 3, the C buckle 100 slides directly with the push plate 3, and it does not contact the slide groove 11, ensuring that the C buckle 100 does not contact other parts during the sliding process of the push plate 3, thereby ensuring that the C buckle 100 does not rotate, so that the bayonet direction of the C buckle 100 does not change, and always faces the workpiece 200, so that the C buckle 100 can be accurately pushed into the annular groove 201 of the workpiece 200 later. At the same time, the supporting groove 32 can limit the C buckle 100, so that the C buckle 100 can be on the push plate 3 and move accurately and stably with the push plate 3; when the push plate 3 is driven to approach the workpiece 2 00, the push plate 3 is sleeved on the periphery of the workpiece 200 through the first avoidance groove 31, so that the push plate 3 and the workpiece 200 are seamlessly connected, and the C buckle 100 will not fall off during the movement of the push plate 3, and at this time, since the edge of the inner hole of the C buckle 100 protrudes in the first avoidance groove 31, the C buckle 100 is directly, accurately and stably stuck in the annular groove 201 of the workpiece 200 under the limiting action of the supporting groove 32, so as to achieve the purpose of automatic assembly of the C buckle, and the assembly quality is high and good; and in the later stage, there is no need to use a cylinder to cooperate with a press-fitting block to press the C buckle from top to bottom into the annular groove of the workpiece, its structure is extremely simple, and the cost is relatively low, so it has strong market competitiveness.

[0029] The structure of the storage rack 2 is described in detail below.

[0030] The storage rack 2 includes a base 21 fixed on the push plate 3 and a storage rod 22 integrally formed on the base 21 and vertically distributed. The front end of the storage rod 22 is provided with a C-shaped and vertically distributed storage trough 221. The base 21 has an escape groove 211 connected to the storage trough 221, so that the lower end of the storage trough 221 extends to the lower end surface of the base 21. The C buckle 100 is buckled in the storage trough 221 at the front end of the storage rod 22, so that the storage trough 221 can store multiple materials in order from bottom to top. The stacked C buckles and the lower end of the storage trough 221 correspond to the supporting groove 32 of the push plate 3, so that the C buckle 100 at the bottom layer can directly fall into the supporting groove 32 of the push plate 3, thereby achieving the purpose of rapid loading. When the push plate 3 pushes out the C buckle 100 at the bottom layer, the next C buckle 100 rests on the push plate 3 until the push plate 3 is reset and the supporting groove 32 of the push plate 3 corresponds to the lower end of the storage trough 221, the C buckle 100 will fall from the storage trough 221 and fall into the supporting groove 32 of the push plate 3.

[0031] The depth of the supporting groove 32 is adapted to, that is, the same as, the thickness of the C buckle 100 .

[0032] The bottom of the base 21 is also provided with a clearance groove 212, and the lower end of the storage rod 22 extends downward to the clearance groove 212, and the lower end surface of the storage rod 22 is flush with the lower end surface of the base 21, so that the lower end surface of the storage rod 22 is above the push plate 3.

[0033] The lower end surface of the base 21 or the lower end surface of the storage rod 22 is provided with a receiving hole 213 for accommodating the workpiece 200. During use, the upper end of the workpiece 200 is inserted into the receiving hole 213, which can further position the workpiece 200 and ensure that the C-clip 100 is later pushed and locked into the annular groove 201 of the workpiece 200. The lower end opening of the receiving hole 213 is provided with a guiding bell mouth 214, which serves as a guide to ensure that the upper end of the workpiece 200 can be stably inserted into the receiving hole 213.

[0034] The storage rod 22 is also provided with a pressing block 23 that can slide up and down. The pressing block 23 presses on the C buckle 100 located on the top layer, and then presses the C buckle 100 downward, so that the C buckle 100 can be driven to fall from the storage trough 221 and fall into the supporting groove 32 of the push plate 3 to achieve the conveying function.

[0035] A sliding channel is formed between the lower end surface of the base 21 and the slide groove 11. The push plate 3 is inserted into this sliding channel, thereby ensuring that the push plate 3 can form a stable limit, thereby achieving stable and high-precision sliding, improving work quality. The push plate 3 is also provided with a sliding portion 33. The lower end surface of the base 21 also has a sliding groove 216 extending upward. The sliding portion 33 is installed in the sliding groove 216 and can slide within the sliding groove 216, further ensuring that the push plate 3 can form a stable limit, thereby achieving more stable and high-precision sliding, improving work quality.

[0036] The push plate 3 is also provided with a stopper 34, which protrudes from the upper end of the sliding portion 33 and prevents the push plate 3 from sliding excessively. The stopper 34 is connected to the power module 4. The power module 4 can be any of a cylinder, a cam-link mechanism, or a motor assembly. In this embodiment, the power module 4 is a cylinder, which has the simplest structure.

[0037] In summary, when the present invention is used, after the storage rack 2 transports the bottom C buckle 100 to the supporting groove 32 of the push plate 3, the C buckle 100 slides directly with the push plate 3, and it does not contact the slide groove 11, ensuring that the C buckle 100 does not contact other parts during the sliding process of the push plate 3, thereby ensuring that the C buckle 100 does not rotate, so that the bayonet direction of the C buckle 100 does not change, and is always facing the workpiece 200, so that the C buckle 100 can be accurately pushed into the annular groove 201 of the workpiece 200 later. At the same time, the supporting groove 32 can limit the C buckle 100, so that the C buckle 100 can be on the push plate 3 and along with the push plate 3 to achieve accurate and stable movement; when the push plate 3 is driven to When approaching the workpiece 200, the push plate 3 is sleeved on the periphery of the workpiece 200 through the first avoidance groove 31, so that the push plate 3 and the workpiece 200 are seamlessly connected, and the C buckle 100 will not fall off during the movement of the push plate 3. At this time, since the edge of the inner hole of the C buckle 100 protrudes in the first avoidance groove 31, the C buckle 100 is directly, accurately and stably inserted into the annular groove 201 of the workpiece 200 under the limiting action of the supporting groove 32, so as to achieve the purpose of automatic assembly of the C buckle, and the assembly quality is high and good; and there is no need to use a cylinder to cooperate with a press-fitting block to press the C buckle from top to bottom into the annular groove of the workpiece in the later stage. Its structure is extremely simple and the cost is relatively low, so it has strong market competitiveness.

[0038] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
