Technical Field

[0001] The utility model relates to the field of pipe fitting processing, in particular to a nut sleeving mechanism. Background Art

[0002] In modern industrial production, the assembly of nuts is a common and important task. However, traditional nut assembly methods often have problems such as low efficiency, difficult to guarantee accuracy, and high labor intensity. In the past, many factories may have relied on manual nut assembly. Workers need to select, position, and install nuts one by one, which is not only time-consuming and laborious, but also prone to human errors, resulting in uneven assembly quality. In some semi-automated assembly systems, although some links have achieved mechanical operation, the coordination and intelligence of the overall process are still insufficient and cannot meet the growing production needs and high-quality standards. Due to the lack of efficient, accurate, and automated nut assembly equipment, production enterprises face great challenges in improving production efficiency, reducing costs, and ensuring product quality stability. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a nut sleeving mechanism that can improve the efficiency of nut sleeving.

[0004] To solve the above technical problems, the utility model provides a nut sleeving mechanism, which includes a vibrating bowl, a sleeving seat movably arranged on one side of the vibrating bowl, and a positioning block arranged on the sleeving seat. The positioning block is provided with a positioning groove for carrying nuts. The discharge port of the vibrating bowl is connected to the positioning groove through a feeding chute. And a tightening cylinder is telescopically arranged on one side of the positioning block. After the nut enters the positioning groove along the feeding chute, the tightening cylinder tightens the nut, and the sleeving seat sleeves the nut onto the pipe fitting.

[0005] Further, there are two relatively arranged limiting blocks on one side of the positioning block, and the two relatively arranged limiting blocks are respectively arranged on both sides of the positioning groove, so that after the nut enters the positioning groove, both sides of the nut are limited by the limiting blocks.

[0006] Further, a guiding block is arranged on the sleeving seat. The guiding block is located on the side of the positioning block close to the pipe fitting, and a guiding groove is opened on the guiding block. The two ends of the guiding groove correspond to the positioning groove and the pipe fitting respectively.

[0007] Further, a positioning cylinder is telescopically arranged on one side of the discharge end of the feeding chute, so that when the previous nut enters the positioning groove, the next nut is positioned by the positioning cylinder.

[0008] Further, there is a bracket on one side of the discharge end of the feeding chute, and the positioning cylinder is arranged on the bracket.

[0009] Further, a detection device for detecting nuts is arranged on the feeding chute.

[0010] Furthermore, the bottom of the sleeve seat is movably mounted on the guide rail, and the moving direction of the sleeve seat is the same as the sleeving direction of the nut.

[0011] Furthermore, a vibrator is provided at the bottom of the material guiding groove.

[0012] Furthermore, a flared structure is provided on one side of the positioning groove close to the material guiding groove.

[0013] The beneficial effects of the present utility model are as follows: When sleeving nuts, a number of nuts are placed in the vibrating bowl, and the vibrating bowl screens and sorts the nuts. Subsequently, the nuts in the vibrating bowl move along the material guiding groove from the discharge port in sequence, so that the nuts enter the positioning groove. At this time, the tightening cylinder extends to tightly position the nuts in the positioning groove. Then, the sleeve seat carries the tightly positioned nuts and moves towards the pipe fitting, and accurately sleeves the nuts onto the pipe fitting. At this time, the pipe fitting sleeved with nuts is taken out, and the sleeve seat can be reset to wait for the sleeving operation of the next nut; during the sleeving process, manual sleeving is not required, which improves the convenience and efficiency of nut sleeving and avoids the problem of human errors.

It is only for the convenience of describing this utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0021] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one element can be one, while in other embodiments, the number of this element can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0022] As Figures 1-4 described, this utility model provides a nut sleeving mechanism, which includes a vibrating disk 1, a sleeving seat 2 movably arranged on one side of the vibrating disk 1, and a positioning block 3 arranged on the sleeving seat 2. The positioning block 3 is provided with a positioning groove 5 for carrying a nut 4. The discharge port of the vibrating disk 1 is connected to the positioning groove 5 through a material guiding groove 6. And a tightening cylinder 7 is telescopically arranged on one side of the positioning block 3. After the nut 4 enters the positioning groove 5 along the material guiding groove 6, the tightening cylinder 7 tightens the nut 4, and the sleeving seat 2 sleeves the nut 4 onto a pipe fitting 8.

[0023] When sleeving the nut, a number of nuts are placed in the vibrating disk, and the vibrating disk screens and sorts the nuts. Subsequently, the nuts in the vibrating disk move along the material guiding groove from the discharge port in sequence, so that the nuts enter the positioning groove. At this time, the tightening cylinder extends to tightly position the nuts in the positioning groove. Then, the sleeving seat moves the nut in the tightened state towards the pipe fitting and accurately sleeves the nut onto the pipe fitting. At this time, the pipe fitting sleeved with the nut is taken out, and the sleeving seat can be reset to wait for the sleeving operation of the next nut. During the sleeving process, manual sleeving is not required, which improves the convenience and efficiency of nut sleeving and avoids the problem of human error.

[0024] Among them, the pipe fitting is fixed by a clamping device to ensure the stability of the pipe fitting during the nut sleeving process. The clamping device can adopt structures such as a clamping die.

[0025] In an embodiment of this solution, the tightening cylinder tightens the side of the nut, so that the relative position of the nut in the positioning groove is limited. Furthermore, during the movement of the sleeving seat, the nut will not shake in the positioning groove and other situations.

[0026] Preferably, one side of the positioning block 3 has two limiting blocks 9 arranged oppositely, and the two oppositely arranged limiting blocks 9 are respectively disposed on both sides of the positioning groove 5, so that after the nut 4 enters the positioning groove 5, both sides of the nut 4 are limited by the limiting blocks 9.

[0027] Specifically, when the nut enters the positioning groove, both of its sides are limited by the limiting blocks, so that the axial direction of the nut is positioned. Subsequently, the tightening cylinder extends to tighten the side of the nut, so that the radial direction of the nut is limited, thereby improving the limiting effect of the nut.

[0028] It is worth mentioning that the distance between the two oppositely arranged limiting blocks is greater than the outer diameter of the pipe fitting and less than the outer diameter of the nut, so as to ensure that the pipe fitting can pass through between the two limiting blocks.

[0029] Preferably, a guiding block 10 is arranged on the sleeving seat 2. The guiding block 10 is located on the side of the positioning block 3 close to the pipe fitting 8, and a guiding groove 11 is formed on the guiding block 10. The two ends of the guiding groove 11 correspond to the positioning groove 5 and the pipe fitting 8 respectively.

[0030] Specifically, when the sleeving seat drives the nut to move towards the pipe fitting, the guiding direction of the pipe fitting is guided through the guiding groove, so as to improve the relative position accuracy between the pipe fitting and the nut, and further ensure that the nut can be sleeved on the outer side of the pipe fitting.

[0031] Preferably, a positioning cylinder 12 is telescopically arranged on one side of the discharging end of the material guiding groove 6, so that when the previous nut 4 enters the positioning groove 5, the next nut 4 is positioned by the positioning cylinder 12.

[0032] Specifically, after the previous nut enters the positioning groove, the tightening cylinder extends to tighten and limit the nut. Subsequently, the positioning cylinder extends to position the next nut, so as to avoid the situation that the nut falls outwards from the material guiding groove when the sleeving seat moves towards the pipe fitting.

[0033] Preferably, one side of the discharging end of the material guiding groove 6 has a bracket 13, and the positioning cylinder 12 is arranged on the bracket 13.

[0034] Specifically, the stability of the positioning cylinder is improved through the bracket, so as to ensure the positioning effect of the positioning cylinder on the nut in the material guiding groove.

[0035] Preferably, a detecting device 14 for detecting the nut 4 is arranged on the material guiding groove 6.

[0036] Specifically, the detecting device detects whether there is material in the material guiding groove, so as to avoid the situation that the sleeving seat still performs sleeving processing while there is no material conveyed in the material guiding groove.

[0037] Among them, the detecting device can adopt an infrared detector, a material sensor, etc.

[0038] Preferably, the bottom of the sleeve seat 2 is movably mounted on the guide rail 15, and the moving direction of the sleeve seat 2 is the same as the sleeving direction of the nut 4.

[0039] Specifically, the moving path of the sleeve seat is limited by the guide rail, so as to improve the accuracy of the relative position between the nut and the pipe fitting when the sleeve seat drives the nut to be sleeved on the pipe fitting.

[0040] It is worth mentioning that during the movement of the sleeve seat along the guide rail, the positioning cylinder still keeps limiting the nut in the material guiding groove to avoid the situation that the nut directly falls outside the positioning groove.

[0041] Among them, the sleeve seat is controlled by a cylinder to reciprocate along the guide rail.

[0042] Preferably, the bottom of the material guiding groove 6 is provided with a vibrator 16, so that the nuts in the material guiding groove are affected by the vibrator, and then a plurality of nuts are stably conveyed along the material guiding groove.

[0043] In an embodiment of the present solution, the vibrator adopts a pneumatic vibrator.

[0044] Preferably, the side of the positioning groove 5 close to the material guiding groove 6 has a flared structure 17, so that when the nut enters the positioning groove from the material guiding groove, the stability of the nut entering can be increased through the flared structure, and the nut is more likely to fall into the inner side of the positioning groove along the flared structure.

[0045] The present utility model is not limited to the above best implementation manner. Anyone can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as it has the same or similar technical solutions as the present application, it falls within the protection scope of the present utility model.
