Description

Technical Field

[0001] This utility model relates to the field of spring nut feeding technology, and in particular to a spring nut feeding pusher. Background Technology

[0002] A spring nut is a special fastener with an integrated elastic structure, consisting of a nut body and a spring element. It combines the threaded connection function of a traditional nut with the elastic compensation characteristics of a spring. A spring nut feeding and pushing machine is a special equipment used in automated assembly scenarios. It realizes automated feeding, orientation sorting and precise pushing of spring nuts. Through the collaboration of mechanical structure and control unit, disordered spring nuts are sorted into a uniform posture and stably pushed to the designated assembly station, replacing manual feeding and improving the efficiency, accuracy and consistency of the spring nut assembly process.

[0003] The existing spring nut feeding pusher is not convenient to adjust the pusher width, which makes it inconvenient to feed spring nuts of different sizes, resulting in limited adaptability of the pusher.

[0004] Therefore, a spring nut feeding pusher is needed to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the above-mentioned spring nut feeding pusher, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a spring nut feeding pusher, which solves the problem that "existing spring nut feeding pushers are not convenient to adjust the pusher width, making it inconvenient to feed spring nuts of different sizes, resulting in limited adaptability of the pusher".

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a spring nut feeding pusher, comprising: The box body has a fixed plate fixedly installed on the inner side of the box body, a pusher plate slidably arranged on the outer wall of the fixed plate, a pushing mechanism fixedly installed at the bottom of the pusher plate, a material ejection mechanism slidably arranged inside the box body, a conveying mechanism arranged on the side of the fixed plate away from the fixed plate, and a stacking scraping mechanism arranged above the conveying mechanism. An adjustment unit is located inside the housing. The adjustment unit includes an extension plate, a first comb tooth, and a second comb tooth. The extension plate and the first comb tooth are used for sliding. The second comb tooth is used to extend the pushing platform to accommodate spring nut materials of different sizes. The feeding unit is located to the side of the adjusting unit. The feeding unit includes a feeding plate and a vibration spring. Under the restriction of the vibration spring, the spring nut is prevented from accumulating on the feeding plate. Under the restriction of the pushing mechanism, the pushing plate can be pushed. The material falling on the fixed plate is conveyed by the conveying mechanism. Under the restriction of the stacking scraping mechanism, the stacked material can be scraped. The material is then returned to the pushing plate in conjunction with the unloading mechanism.

[0009] In a preferred embodiment of the spring nut feeding pusher of this utility model, the adjusting unit includes a sleeve block fixedly installed at the bottom of the pusher plate, a threaded rod is sleeved inside the sleeve block, a fixed block is rotatably connected to the end of the threaded rod, a limit sleeve is provided on the outside of the fixed block, a limit rod is slidably provided inside the limit sleeve, and a retaining ring is fixedly installed at the end of the limit rod.

[0010] In a preferred embodiment of the spring nut feeding pusher of this utility model, an extension plate is fixedly installed at the end of the limiting rod away from the retaining ring, and a first comb tooth is fixedly installed at the end of the extension plate away from the limiting rod, and the first comb tooth meshes with a second comb tooth.

[0011] In a preferred embodiment of the spring nut feeding pusher of this utility model, the second comb teeth are alternately slidably arranged with the first comb teeth, and the second comb teeth are fixedly installed on the top surface of the fixed plate and the pusher plate respectively. Under the constraint of the alternate first comb teeth and the second comb teeth, the material placement platform of the fixed plate and the pusher plate can be widened so as to feed spring nuts of different sizes.

[0012] In a preferred embodiment of the spring nut feeding pusher of this utility model, the threaded rod is threadedly fitted inside the sleeve block, and the end of the threaded rod is rotatably connected to the side wall of the fixed block. Under the restriction of the limiting rod, the rotating threaded rod can push the fixed block under the restriction of the sleeve block, so that the fixed block drives the extension plate and the first comb tooth to move, thereby widening the fixed plate and the pusher plate placement platform.

[0013] In a preferred embodiment of the spring nut feeding pusher of this utility model, the feeding unit includes a rotating shaft fixedly installed inside the housing, a feeding plate rotatably connected to the outer wall of the rotating shaft, a vibration spring fixedly installed at the bottom of the feeding plate, and a support block fixedly installed at the end of the vibration spring away from the feeding plate.

[0014] In a preferred embodiment of the spring nut feeding pusher of this utility model, the outer wall of the support block is fixedly installed to the inner side of the box, and the support block is placed below the feeding plate. Under the support of the support block, the vibration spring stably supports the feeding plate.

[0015] As a preferred embodiment of the spring nut feeding pusher of this utility model, there are two vibration springs, which are symmetrically distributed around the center line of the feeding plate. Under the constraint of the two vibration springs, the feeding plate can be stably pushed, causing the feeding plate to deflect towards the pusher plate and vibrate to feed the material.

[0016] The beneficial effects of this utility model are as follows: When feeding, if it is necessary to adapt to spring nuts of different sizes, the threaded rod can be rotated. Under the limitation of the limiting rod and the limiting sleeve, the threaded rod pushes the fixed block, which drives the expansion plate and the first comb tooth away from the second comb tooth, widening the material placement platform of the fixed plate and the push plate. At the same time, the distance between the conveying mechanism and the fixed plate can be adjusted. When pushing, the pushing mechanism drives the push plate to slide and feed the material. The material falls to the conveying mechanism, the stacking and scraping mechanism removes the stacked material, and the remaining material falls to the unloading mechanism, which feeds the material again by the push plate (the box, pushing mechanism, conveying mechanism, unloading mechanism and stacking and scraping mechanism are existing known technologies, so their structures are not fully described). When material is added to the feeding plate, the material's gravity presses down on the feeding plate, causing it to rotate around the shaft and compress the vibration spring. The feeding plate tilts to guide the material, and when the vibration spring returns to its original position, it pushes the feeding plate back to the center. This reciprocating motion gradually feeds the material and prevents it from accumulating. Attached Figure Description

[0028] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a spring nut feeding pusher, comprising: The box 100 has a fixed plate 101 fixedly installed inside the box 100. A pusher plate 102 is slidably arranged on the outer wall of the fixed plate 101. A pusher mechanism 103 is fixedly installed at the bottom of the pusher plate 102. A material discharge mechanism 104 is slidably arranged inside the box 100. A conveying mechanism 105 is arranged on the side of the fixed plate 101 away from the fixed plate 101. A stacking scraping mechanism 106 is arranged above the conveying mechanism 105. Adjustment unit 200 is located inside the housing 100. Adjustment unit 200 includes extension plate 207, first comb tooth 208 and second comb tooth 209. The extension plate 207 and first comb tooth 208 are used for sliding. The second comb tooth 209 is used to extend the pushing platform to accommodate spring nut materials of different sizes. The feeding unit 300 is located to the side of the adjusting unit 200. The feeding unit 300 includes a feeding plate 302 and a vibration spring 303, which is used to prevent the spring nut from accumulating on the feeding plate 302 under the restriction of the vibration spring 303.

[0029] In use, under the constraint of the pushing mechanism 103, the pushing plate 102 can be pushed, and the material falling on the fixed plate 101 is conveyed by the conveying mechanism 105. Under the constraint of the stacking scraping mechanism 106, the stacked material can be scraped, and the material is returned to the pushing plate 102 in conjunction with the unloading mechanism 104.

[0030] Example 2 Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows: The adjustment unit 200 includes a sleeve block 201 fixedly installed at the bottom of the pusher plate 102. A threaded rod 202 is sleeved inside the sleeve block 201. A fixing block 203 is rotatably connected to the end of the threaded rod 202. A limit sleeve 206 is provided on the outside of the fixing block 203. A limit rod 204 is slidably provided inside the limit sleeve 206. A retaining ring 205 is fixedly installed at the end of the limit rod 204. An extension plate 207 is fixedly installed at the end of the limit rod 204 away from the retaining ring 205. A first comb tooth 208 is fixedly installed at the end of the extension plate 207 away from the limit rod 204. The first comb tooth 208 meshes with a second comb tooth 209.

[0031] The second comb tooth 209 is slidably arranged with the first comb tooth 208. The second comb tooth 209 is fixedly installed on the top surface of the fixed plate 101 and the push plate 102 respectively. Under the constraint of the interlaced first comb tooth 208 and second comb tooth 209, the material placement platform of the fixed plate 101 and the push plate 102 can be widened so as to feed spring nuts of different sizes.

[0032] The threaded rod 202 is threadedly fitted inside the sleeve block 201, and the end of the threaded rod 202 is rotatably connected to the side wall of the fixed block 203. Under the restriction of the limiting rod 204, the rotating threaded rod 202 can push the fixed block 203 under the restriction of the sleeve block 201, so that the fixed block 203 drives the extension plate 207 and the first comb tooth 208 to move, thereby widening the platform of the fixed plate 101 and the push plate 102.

[0033] When feeding the spring nut, the widths of the fixing plate 101 and the pusher plate 102 need to be adjusted according to the size of the spring nut. At this time, rotating the threaded rod 202 causes the threaded rod 202 to rotate inside the sleeve block 201, pushing the fixing block 203 rotatably connected to its end. This pushes the fixing block 203, causing the expansion plate 207 and the first comb tooth 208 to slide away from the second comb tooth 209. This, in turn, causes the fixing plate 101 and the pusher plate 102 to rotate. 02 The feeding platform is widened to feed spring nuts of different sizes. Under the restriction of the pushing mechanism 103, the pushing plate 102 can be pushed so that the pushing plate 102 slides inside the box 100 to push the spring nuts. The material falls on the conveying mechanism 105. The stacked material is removed by the stacking scraping mechanism 106 and falls on the unloading mechanism 104. The material is fed again by the sliding pushing plate 102. When pushing spring nuts of different sizes, the width of the fixed plate 101 is adjusted, and the distance between the conveying mechanism 105 and the fixed plate 101 is adjusted at the same time to achieve adaptive feeding.

[0034] Example 3 Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below: The feeding unit 300 includes a rotating shaft 301 fixedly installed inside the housing 100. A feeding plate 302 is rotatably connected to the outer wall of the rotating shaft 301. A vibration spring 303 is fixedly installed at the bottom of the feeding plate 302. A support block 304 is fixedly installed at the end of the vibration spring 303 away from the feeding plate 302.

[0035] The outer wall of the support block 304 is fixedly installed to the inner side of the box 100. The support block 304 is placed below the feeding plate 302. Under the support of the support block 304, the vibration spring 303 stably supports the feeding plate 302.

[0036] There are two vibration springs 303, which are symmetrically distributed around the center line of the feeding plate 302. Under the constraint of the two vibration springs 303, the feeding plate 302 can be stably pushed, so that the feeding plate 302 deflects and vibrates to feed material towards the pusher plate 102.

[0037] In use, when feeding the spring nut, the material is added above the feeding plate 302. Under the action of the material's gravity, the feeding plate 302 is pressed, causing it to rotate around the point where it is connected to the rotating shaft 301 as the rotation center, and compressing the vibration spring 303. At this time, the feeding plate 302 is tilted, guiding the spring nut to the push plate 102. Under the elastic action of the vibration spring 303, the feeding plate 302 can be reset and pushed, achieving a gradual feeding effect through reciprocating motion, and preventing the material from accumulating on the feeding plate 302 and stagnating.

[0038] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0039] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
