Description

Technical Field

[0001] This utility model relates to the field of tooling transfer racks, specifically, to a foldable assembly line pin tooling. Background Technology

[0002] With the completion of coal mine hydraulic support assembly lines and the accelerating pace of production, traditional pin-mounting fixtures, due to their non-foldable and non-stacking design, not only occupy a significant amount of assembly line space when pins are not needed, but also affect the material transportation efficiency of the assembly line. Moreover, when such fixtures are transported without pins, their non-foldable and non-stacking design prevents full utilization of truck space, resulting in a substantial waste of transportation costs.

[0003] To address the aforementioned issues, a metal ingot stacking rack, as disclosed in Chinese Utility Model Patent CN202322712168.2, includes a stacking rack body 1. The stacking rack body 1 includes a load-bearing placement plate 5 and a support column 2 for supporting the load-bearing placement plate 5. Rotary connecting seats 4 are installed on the front and rear sides of the load-bearing placement plate 5 near the left and right ends of the support column 2. One end of the rotary connecting seat 4 is rotatably connected to the side of the load-bearing placement plate 5 via a rotating rod 16. The other end of the rotary connecting seat 4 is equipped with a support column 9 of a protective baffle 8. When the protective baffle 8 is open, it is located on top of the support column 2. When the protective baffle 8 is folded, it is located on top of the load-bearing placement plate 5. An anti-collision buffer pad 13 is provided on the bottom surface of the lower end of the support column 9. When the protective baffle 8 is in a vertical state, the anti-collision buffer pad 13 contacts the top surface of the support column 2. The anti-collision buffer pad 13 can effectively buffer the adjustment process. The cross-sectional dimensions of the support column 9 are the same as those of the support column 2.

[0004] Although the solution in the aforementioned public document can achieve the folding of the tooling and the stacking of the tooling during folding, the support column 9 only contacts the top surface of the support column 2 through the anti-collision buffer pad 13, without limiting the protective frame 8 (i.e. guardrail). There may be relative displacement between the support column 9 and the support column 2, resulting in poor stability and certain risks when loading workpieces.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a foldable assembly line pin tooling. When the workpiece is folded, it overlaps to save space, and when the workpiece is unfolded, the folding rod is confined within the support legs to enhance stability.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: It includes a base and a guardrail. The base includes supporting legs, and the guardrail includes a folding rod. The folding rod is rotatably mounted on the supporting legs. The top of the supporting legs is a hollow rod, and the side wall of the hollow rod has an open groove. When the folding rod rotates, it passes through the open groove and embeds itself into the hollow rod. When the folding rod is embedded in the hollow rod, the two are parallel. The bottom end of the supporting legs has a stacking groove, and the top of the hollow rod can be embedded into the stacking groove along the length direction of the supporting legs. The side wall of the hollow rod has an oblong hole, and the bottom of the folding rod has a rotating shaft. The rotating shaft is rotatably disposed within the oblong hole and can slide along the length direction of the oblong hole to allow the folding rod to slide along the length direction of the supporting legs. The top of the hollow rod has a limiting groove, which is an open groove. The side wall of the folding rod has a limiting block that can slide downward into the limiting groove.

[0008] By rotatably and slidably setting the pivot of the folding rod in the waist-shaped hole of the hollow rod, and by the embedded cooperation of the limiting block of the folding rod and the limiting groove of the hollow rod, the folding rod can be folded on the support leg, that is, the guardrail can be folded on the base. Moreover, during folding, the workpieces can be stacked on top of each other through the stacking groove. The stacking of workpieces saves space when folding. When the workpiece is unfolded, the limiting block and the limiting groove can limit the entire folding rod within the support leg, enhance the stability of the foldable guardrail on the base when unfolded, and ensure the overall stability of the fixture when carrying the workpiece.

[0009] Based on the above, a reinforcing plate is installed on the side wall of the support leg. The reinforcing plate is used to strengthen the structural strength of the waist-shaped hole and the limiting groove on the hollow rod. The reinforcing plate is provided with reinforcing holes corresponding to the waist-shaped hole and the limiting groove.

[0010] By setting up reinforcing plates, the overall structural strength of the hollow rods on the support legs can be enhanced, the structural strength of the hollow rods that were reduced due to the presence of open slots, waist-shaped holes, and limiting slots can be increased, the contact area between the rotating shaft and the bottom of the waist-shaped hole can be increased, and the contact area between the limiting block and the limiting slot can be increased, enabling the support legs to bear greater loads.

[0011] Based on the above, the reinforcing plate is disposed on the outer wall of the support leg, and the top of the hollow rod and the reinforcing plate can be embedded together into the stacking groove.

[0012] By using reinforcing plates as reinforcements during stacking, the overall stability of the tooling can also be enhanced during stacking.

[0013] Based on the above, the top of the folding rod is provided with an insert, and the top of the folding rod can be inserted into the stacking slot along the length direction of the support leg through the insert.

[0014] By setting up inserts, the folding rod can be stably embedded into the stacking slot, enhancing the stability of the tooling when the guardrail is unfolded.

[0015] Based on the above, the bottom of the folding rod is provided with a shaft cylinder, the rotating shaft is a pin, and the pin is rotatably disposed in the shaft cylinder and the waist-shaped hole.

[0016] The use of a shaft, pin, and oblong hole prevents the folding rod from jamming when rotating.

[0017] Based on the above, the bottom of the support leg is provided with a base block, and the stacking groove is provided on the base block.

[0018] Enhancing the overall stability of the tooling by using the base block also helps to strengthen the structural strength of the support legs.

[0019] Based on the above, hooks are provided on the side wall of the support leg to facilitate lifting.

[0020] Based on the above, the folding rods are connected by guardrail crossbars to form the guardrail, and the guardrail is also provided with a handle for lifting the guardrail.

[0021] The horizontal guardrails can enhance the structural strength of the work equipment guardrails, while the handles make it easy for workers to lift and fold or unfold the guardrails.

[0022] Based on the above, the support legs are connected by a base beam to form the base, the end of the base beam is installed on the lower side of the open slot of the support leg, and the end of the base beam is installed in the middle of the support leg.

[0023] The base beam helps to enhance the structural strength of the tooling base and also facilitates forklift transport of the tooling.

[0024] Based on the above, the base has guardrails on opposite sides as guardrail sides, and the other two sides of the base are open sides. The guardrail side of the base has a side plate above the base beam that connects the two support legs.

[0025] The side plate acts as a base baffle to prevent workpieces from falling off the base. The open side of the base makes it easy to load workpieces, especially hydraulic support pins, and also facilitates the folding of the guardrail. Attached Figure Description

Detailed Implementation

[0028] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0029] Example 1 like Figures 1-6 As shown, the foldable assembly line pin tooling of this embodiment includes a base and a guardrail. The base includes a support leg 1, and the guardrail includes a folding rod 2. The folding rod 2 of the guardrail is rotatably mounted on the support leg 1. The guardrail can be folded or unfolded as a whole on the base through the folding rod 2. When the guardrail is folded, it saves space and facilitates the overall transportation of the tooling. When the guardrail is unfolded, it enables the tooling to carry more workpieces.

[0030] The folding rod 2 is rotatably mounted on the support leg 1 of the base. Meanwhile, the top of the support leg 1 is a hollow rod 11. The side wall of the hollow rod 11 is provided with an open groove 12. When the folding rod 2 rotates, it is inserted into the hollow rod 11 through the open groove 12. When the folding rod 2 is inserted into the hollow rod 11, the two are parallel, that is, the guardrail can be unfolded.

[0031] The base has a support plate between the support legs 1. The support plate is used to place the workpiece. The guardrail can be rotated toward the support plate by the folding rod 2 to complete the folding.

[0032] The folding rod 2 is rotated and embedded into the hollow rod 11 through the open slot 11, so that the folding rod 2 can be unfolded or folded on the support leg 1, that is, the guardrail can be unfolded or folded on the base.

[0033] The support leg 1, hollow rod 11 and folding rod 2 are preferably made of metal square tubes. When all three are made of metal square tubes, the hollow rod 11 is the upper part of the support leg 1. One side of the hollow rod 11 is set as an open side to form an open groove 12. The diameter of the folding rod 2 is smaller than the diameter of the support leg 1 and the hollow rod 11 so that the folding rod 2 can be embedded into the inner cavity of the hollow rod 11.

[0034] The bottom end of the support leg 1 is provided with a stacking groove 13. The top end of the hollow rod 11 can be embedded into the stacking groove 13 along the length direction of the support leg 1. By interlocking the top end of the hollow rod 11 of one set of fixtures with the stacking groove 13 of another set of fixtures, multiple fixtures can be stacked on top of each other to achieve stacking of fixtures in a folded state, saving the space occupied by the fixtures.

[0035] The hollow rod 11 has a waist-shaped hole 14 on its side wall, and the folding rod 2 has a pivot 22 at its bottom. The pivot 22 is rotatably disposed within the waist-shaped hole 14. The length direction of the waist-shaped hole 14 is along the length direction of the support leg 1. The waist-shaped hole 14 is disposed on the side walls on opposite sides of the hollow rod 11, and can be configured as a through hole on the side wall of the hollow rod 11, allowing the pivot 22 to pass through the waist-shaped hole 14. Thus, when the folding rod 2 is parallel to the support leg 1, that is, when the folding rod 2 is fully embedded in the hollow rod 11, the pivot 22 can slide within the waist-shaped hole 14 along the length direction of the waist-shaped hole 14, allowing the folding rod 2 to slide along the length direction of the support leg 1.

[0036] The hollow rod 11 has a limiting groove 15 at its top end. The limiting groove 15 is an upward-opening groove. The side wall of the folding rod 2 has a limiting block 23 that can slide downward into the limiting groove 15. When the folding rod 2 is parallel to the support leg, that is, when the folding rod 2 is fully embedded in the hollow rod 11 and slides downward, the limiting block 23 can be embedded in the limiting groove 15 to restrict the rotation of the folding rod 2.

[0037] By rotatably and slidably setting the pivot 22 of the folding rod 2 in the waist-shaped hole 14 of the hollow rod 11, and by the embedded cooperation of the limiting block 23 of the folding rod 2 and the limiting groove 15 of the hollow rod 11, the folding rod 2 can be folded on the support leg 1, that is, the guardrail can be folded on the base. Moreover, while folding, the workpieces can be stacked on each other through the stacking groove 13. The stacking of the workpieces saves space when they are folded. When the workpieces are unfolded, the limiting block 23 and the limiting groove 15 can limit the folding rod 2 as a whole within the support leg 1, enhance the stability of the foldable guardrail on the base when it is unfolded, and ensure the overall stability of the tooling when it carries the workpiece.

[0038] Example 2 Based on Embodiment 1, in this embodiment, a reinforcing plate 16 is installed on the side wall of the support leg 1. The reinforcing plate 16 is used to strengthen the structural strength of the waist-shaped hole 14 and the limiting groove 15 on the hollow rod 11. The reinforcing plate 16 is provided with reinforcing holes corresponding to the waist-shaped hole 14 and the limiting groove 15.

[0039] By setting the reinforcing plate 16, the overall structural strength of the hollow rod 11 on the support leg 1 can be enhanced, the structural strength of the hollow rod 11 which was reduced due to the presence of the open slot 12, the waist-shaped hole 14, and the limiting slot 15 can be enhanced, the contact area between the rotating shaft 22 and the bottom of the waist-shaped hole 14 can be increased, and the contact area between the limiting block 23 and the limiting slot 15 can be increased, so that the support leg 1 can bear a larger load.

[0040] Example 3 Based on Embodiment 2, in this embodiment, the reinforcing plate 16 is disposed on the outer wall of the side walls on both sides of the support leg 1. The top of the hollow rod 11 and the reinforcing plate 16 can be embedded into the stacking groove 13 along the length direction of the support leg 1. By using the reinforcing plate 16 as a reinforcing member when stacking, the overall stability of the tooling can also be enhanced when stacking.

[0041] Based on the above, a base block 17 is provided at the bottom of the support leg 1, and a stacking groove 13 is provided on the base block 17. The base block 17 enhances the overall stability of the tooling and also helps to enhance the structural strength of the support leg 1.

[0042] Example 4 Based on Embodiment 1, Embodiment 2 or Embodiment 3, in this embodiment, the top end of the folding rod 2 is provided with an insert 21, and the top end of the folding rod 2 can be embedded into the stacking groove 13 along the length direction of the support leg 1 through the insert 21.

[0043] By setting the insert 21, the folding rod 2 can be stably embedded into the stacking slot 13, enhancing the stability of the tooling stacking when the guardrail is unfolded.

[0044] When the reinforcing plate 16 is set, the cross-sectional shape of the insert 21, the cross-sectional shape of the hollow rod 11 and the reinforcing plate 16, and the cross-sectional shape of the stacking groove 13 are mutually compatible.

[0045] As shown in the figure, when a total of four support legs 1 and folding rods 2 are set to make the fixture into a rectangular fixture, the insert 21 can be set only on the adjacent side walls on both sides of the folding rod 2, and the shapes of the inserts 21 on the two adjacent folding rods 2 are mirror symmetrical. In this way, the combined action of the inserts 21 on the four folding rods 2 on the guardrail can keep the fixture stable when it is stacked. Moreover, there is enough gap between the insert 21 and the stacking groove 13 as a buffer space, which also makes it easy to align the insert 21 and the stacking groove 13 so that the two can be quickly inserted.

[0046] Example 5 Based on Embodiment 1, in this embodiment, the bottom of the folding rod 2 is provided with a shaft cylinder 24, and the rotating shaft 22 is a pin. The pin is rotatably disposed in the shaft cylinder 24 and the waist-shaped hole 14. A cotter pin is inserted at the end of the pin to prevent axial displacement when the pin rotates.

[0047] The cooperation of the shaft sleeve 24, the pin and the waist-shaped hole 14 prevents the folding rod 2 from getting stuck when rotating.

[0048] Example 6 Based on Embodiment 1, in this embodiment, the support leg 1 is provided with a hook 18 on the side wall opposite to the side wall with the open groove 12 to facilitate lifting.

[0049] Furthermore, in this embodiment, the folding rods 2 are connected by a guardrail horizontal plate 4 to form a guardrail. The guardrail is also equipped with a carrying handle 6 for lifting it. The carrying handle 6 can be installed on the guardrail horizontal plate 4, or it can be formed by connecting two folding rods 2. A reinforcing triangular plate can be installed between the folding rods 2 and the guardrail horizontal plate 4 to enhance the structural strength of the guardrail. The guardrail horizontal plate 4 enhances the structural strength of the tool guardrail, and the carrying handle 6 allows workers to easily lift and fold or unfold the guardrail.

[0050] Furthermore, in this embodiment, the support legs 1 are connected by a base beam 3 to form a base. The end of the base beam 3 is installed on the lower side of the open slot 12 of the support leg 1. A grid-shaped reinforcing beam can also be provided between the base beams 3, and a reinforcing triangular plate can be provided between the base beam 3 and the support leg 1 to enhance the structural strength of the base. The end of the base beam 3 is installed in the middle of the support leg 1, and a gap is left at the bottom of the base beam 3 for forklift lifting. The base beam 3 helps to enhance the structural strength of the tooling base and also facilitates forklift transportation of the tooling.

[0051] Furthermore, in this embodiment, the base includes four support legs 1, thereby forming a rectangular base. The base has guardrails on opposite sides as guardrail sides, and the other two sides of the base have open sides above the base beams 3. The guardrail side has a side plate 5 connecting the two support legs 1 above the base beams 3. The side plate 5 serves as a base baffle to prevent workpieces from falling off the base. The open sides of the base can conveniently load workpieces, especially hydraulic support pins, and also facilitate the folding of the guardrails.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
