Description

Technical Field

[0001] This utility model belongs to the field of assembly technology, specifically relating to an assembly structure of a rubber wheel and a metal column. Background Technology

[0002] Injection molds are tools used to produce rubber products, giving them a complete structure and precise dimensions. During production, the injection molding machine heats and melts the rubber material, injects it into the mold cavity under high pressure, and after cooling and solidification, a molded rubber part is obtained.

[0003] After the injection molded product is formed, it needs to be assembled. For products like rubber wheels, in order to be suitable for office automation applications, two or more rubber wheels are usually inserted through the metal column (for example, two rubber wheels are fitted on the shaft of a printer, mainly to ensure stable paper transmission and reduce friction).

[0004] Assembling the metal pillars manually by picking them up and then fitting the rubber wheels is inefficient, requiring a large amount of manpower and wasting costs. Furthermore, the rubber wheels need to be precisely positioned on the metal pillars during assembly; manual assembly alone cannot guarantee the accuracy of the wheel placement, resulting in a low yield rate and rework issues. Utility Model Content

[0005] This invention provides an assembly structure for a rubber wheel and a metal column, which solves the problems of low efficiency and inability to guarantee the quality of finished products in manual assembly.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a rubber wheel and metal column assembly structure, which includes:

[0007] Base plate;

[0008] The press-fitting assembly includes a mounting block fixed at intervals to the top of the base plate, a metal column groove horizontally penetrating the mounting block, and a rubber groove formed on the mounting block, wherein the rubber groove and the metal column groove are coaxially arranged.

[0009] The pushing assembly includes a support platform fixed to the top of the base plate, a support groove formed on the top of the support platform, a first push plate movably disposed on the top of the base plate, and a push column fixed to the bottom of the first push plate. The push column is used to push the metal column on the support groove into the metal column groove.

[0010] The feeding assembly includes a support plate fixed to the top of the base plate, support blocks fixed at intervals to the top of the support plate, support grooves opened on the top of the support blocks, and guide mechanisms disposed on both sides of the support plate. The guide mechanisms are used to push the metal columns in the support grooves to be flush with the base plate.

[0011] A transfer assembly, fixed to the top of the base plate, is used to clamp the metal column in the support groove and transfer it to the bearing groove.

[0012] Optimally, the press-fit assembly further includes a first clearance groove formed on the top of the mounting block and communicating with the metal column groove, a second clearance groove formed on the top of the mounting block and communicating with the rubber groove, and a top block that is vertically and flexibly disposed between the mounting blocks, the top block being used to lift the metal column after press-fitting.

[0013] Optimally, the feeding assembly further includes a first slide rail fixed to the top of the base plate, a first slider slidably mounted on the first slide rail, a pad fixed to the top of the first slider, and a first push cylinder fixed to the top of the base plate and connected to the first push plate, wherein the first push plate is fixed to the top of the pad.

[0014] Ideally, the diameter of the pusher is smaller than the diameter of the bearing groove, and the first pusher plate is higher than the upper surface of the bearing platform.

[0015] Optimally, the guiding mechanism includes an adjusting plate that is adjustablely fixed to the top of the base plate, a baffle integrally connected to the side of the adjusting plate near the support plate, an adjusting groove that passes through the adjusting plate, and a second push plate that is movably disposed on the top of the support plate. The second push plate is used to push the metal column in the support groove to abut against the baffle.

[0016] Optimally, the transfer assembly includes a gantry frame mounted above the feeding assembly and the pushing assembly, a movable plate movably mounted on the top of the gantry frame, a lifting plate movably mounted on one side of the movable plate, and a finger cylinder fixed to the bottom of the lifting plate. The finger cylinder is used to grip the metal column in the support groove and transfer it to the bearing groove.

[0017] Optimally, the pressing assembly further includes a lifting cylinder fixed to the bottom of the base plate, a top plate connected to the lifting cylinder, a top groove formed on the top of the top block, and a lifting slot penetrating the base plate. The top block is fixed to the top of the top plate, and the top plate is placed in the lifting slot.

[0018] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0019] This utility model's assembly structure for a rubber wheel and a metal column uses a feeding assembly to guide the metal column, ensuring one side of the metal column is flush. Then, a transfer assembly picks up the guided metal column and places it on the bearing groove of a pushing assembly. The first push plate and push column push the metal column forward into the rubber wheel of the mounting block, completing the assembly of the metal column and the rubber wheel. Finally, the top block ejects the finished product. This improves the efficiency of assembling the metal column and the rubber wheel, and enables efficient and accurate positioning of the metal column, increasing the pass rate of the finished product and avoiding rework.

[0029] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0030] like Figure 2 , 3 The diagram shown is a structural schematic of the assembly structure of the rubber wheels and the metal column of this utility model. It is typically used to fit two rubber wheels (finished products such as...) at intervals on a metal column (such as an iron column). Figure 1 (As shown). The assembly structure includes a support column 1, a base plate 2, a pressing assembly, a pushing assembly, a feeding assembly, and a transfer assembly. The transfer assembly is used to pick up the guided metal column from the feeding assembly and transfer it to the pushing assembly. The pushing assembly then pushes the metal column onto the pressing assembly, thus completing the assembly of the metal column and the rubber wheel.

[0031] The base plate 2 is fixed to the top of the support column 1 by screws or welding. There are at least four support columns 1 (preferably four support columns 1 for cost considerations, and the four support columns 1 are located at the four corners of the bottom of the base plate 2). The base plate 2 is supported by the support columns 1 to provide installation space for the subsequent lifting cylinder 8.

[0032] like Figure 4 The diagram shows the structure of the feeding assembly, which includes a support plate 32, support blocks 33, support grooves 34, a second push cylinder 35, a second push plate 36, an adjusting plate 37, a baffle 38, and an adjusting groove 39. The support plate 32 is fixed to the top of the base plate 2 by screws. Multiple support blocks 33 are fixed to the top of the support plate 32 by welding. Support grooves 34 are formed on the top of the support blocks 33 to support metal columns placed thereby by the operator.

[0033] like Figure 4 As shown, each pair of support blocks 33 forms a group, and the two support blocks 33 are used to support a metal column to be pressed. The cross-section of the support groove 34 is semi-circular, and the diameter of the support groove 34 is equal to the diameter of the metal column. Therefore, when the operator places the metal column on the support groove 34, the lower half of the metal column is placed inside the support groove 34, while the upper half of the metal column extends beyond the support block 33, which facilitates the placement and removal of the metal column.

[0034] A gap is left between two adjacent sets of support blocks 33. When the transfer assembly grips the transfer metal column, it ensures that the finger cylinder 29 can descend to both sides of the metal column to grip it.

[0035] The adjusting groove 39 is a rounded rectangle that extends through the adjusting plate 37. A through hole is provided on the base plate 2 to mate with the adjusting groove 39. During actual fixing, the fastening bolt is passed through the adjusting groove 39 and the through hole, and a fastening nut is used on the other side to secure the adjusting plate 37. By providing an adjustable adjusting plate 37, the operability and adaptability of the assembly structure are improved, allowing the operator to adjust the position of the adjusting plate 37 appropriately according to the actual situation.

[0036] The baffle 38 is integrally connected to the adjusting plate 37 on the side near the support plate 32, and the baffle 38 and the adjusting plate 37 form an "L" shape. The cylinder body of the second push cylinder 35 is fixed to the top of the fixing plate by screws, and the fixing plate is fixed to the top of the base plate 2 by screws. The fixing plate raises the height of the second push cylinder 35, preventing its piston rod from tilting when the second push cylinder 35 is working.

[0037] The second push cylinder 35 can be a commercially available linear cylinder. The second push plate 36 is connected to the piston rod of the second push cylinder 35. The second push cylinder 35 pushes the second push plate 36, which in turn pushes the metal column in the support groove 34 until it abuts against the baffle 38, ensuring that one side of the metal column is flush and improving the pass rate of the finished product after pressing.

[0038] Because the operator cannot guarantee that the metal column is level after placing it in the support groove 34, if it is directly placed on the bearing groove 20, the position of the rubber wheel press-fit will be inconsistent, requiring rework and readjustment, which wastes time and increases costs.

[0039] like Figure 2 As shown, the transfer assembly is fixed to the top of the base plate 2 and is mounted above the feeding assembly and the pushing assembly. The transfer assembly is used to clamp the guided metal column and then place it on the pushing assembly, which pushes the metal column into the rubber wheel. The transfer assembly includes a gantry frame 21, a linear slide table 22, a second slide rail 23, a second slider 24, a moving plate 25, a connecting plate 26, a slide table cylinder 27, a lifting plate 28, a finger cylinder 29, a clamping plate 30, and a clamping groove 31.

[0040] The gantry frame 21 is in the shape of an inverted "]", with the opening of the "]" shaped gantry frame 21 facing downwards. The gantry frame 21 is fixed to the top of the base plate 2 by welding. The linear slide table 22 is fixed to the top of the gantry frame 21 by screws. The moving plate 25 is fixed to the sliding part of the linear slide table 22. The linear slide table 22 drives the moving plate 25 to move back and forth between the feeding assembly and the pushing assembly, thereby realizing the transfer of the metal column.

[0041] Since the moving plate 25 extends above the feeding assembly, to improve the stability of the moving plate 25 during movement, the second slide rail 23 is fixed to the top of the gantry frame 21 by screws. The second slider 24 is slidably mounted on the second slide rail 23, and the side of the moving plate 25 away from the feeding assembly is fixed to the second slider 24. When the linear slide table 22 drives the moving plate 25 to reciprocate between the feeding assembly and the pushing assembly, it will drive the second slider 24 to move along the length of the second slide rail 23, thereby improving the stability of the moving plate 25 during movement.

[0042] The connecting plate 26 is fixed to the side of the moving plate 25 away from the second slide rail 23 by welding and is vertically arranged. The slide cylinder 27 is fixed to the side of the connecting plate 26 away from the moving plate 25 by screws. The lifting plate 28 is connected to the sliding part of the slide cylinder 27. The slide cylinder 27 drives the lifting plate 28 to move up and down, which in turn drives the finger cylinder 29 to descend to clamp the guided metal column.

[0043] The finger cylinder 29 is fixed to the bottom of the lifting plate 28 by screws. The finger cylinder 29 has two finger arms. The clamping plate 30 is fixed to the finger arms of the finger cylinder 29 by screws. Therefore, the finger cylinder 29 drives the two clamping plates 30 to move inward or open outward simultaneously.

[0044] The clamping groove 31 is located on the opposite side of the two clamping plates 30. The clamping groove 31 is arc-shaped. The linear slide 22 drives the moving plate 25 to move above the feeding assembly. The linear slide 22 drives the lifting plate 28 to descend. At the same time, the finger cylinder 29 drives the two clamping plates 30 to open outward. Then, the finger cylinder 29 drives the two clamping plates 30 to move inward to clamp the guided metal column. Under the drive of the linear slide 22, it is transferred to the pushing assembly.

[0045] like Figure 5 , 6 As shown, the material pushing assembly includes a first slide rail 13, a first slider 14, a pad 15, a first push plate 16, a first push cylinder 17, a push column 18, a support platform 19, and a support groove 20. There are at least two support platforms 19, which are fixed to the top of the base plate 2 by welding (in this solution, for cost considerations, two support platforms 19 are preferred). The support groove 20 is located on the top of the support platform 19. The support groove 20 is semi-circular and its diameter is equal to that of the metal column. Therefore, when the finger cylinder 29 places the metal column on the support groove 20, the lower half of the metal column will be inserted into the support groove 20, while the upper half of the metal column will protrude above the support platform 19, which facilitates the placement of the metal column. (If the cross-section of the support groove 20 is larger than a semi-circle, i.e., the central arc angle is greater than 180°, the metal column will be stuck on the support platform 19 when it is placed. If the cross-section of the support groove 20 is smaller than a semi-circle, i.e., the central arc angle is less than 180°, the metal column is likely to fall out from the side of the support groove 20 when it is pushed.)

[0046] At least two first slide rails 13 are fixed to the top of the base plate 2 by screws (in this embodiment, preferably two first slide rails 13 are located on both sides of the support platform 19, and the length direction of the first slide platform is parallel to the length direction of the metal column on the feeding assembly). The first slider 14 is slidably mounted on the first slide rail 13, the pad 15 is fixed to the top of the first slider 14, and the first push plate 16 is fixed to the top of the pad 15 by screws.

[0047] like Figure 6 As shown, the first push plate 16 is lifted up by the pad 15 until the lower surface of the first push plate 16 is higher than the upper surface of the support platform 19. When the first push cylinder 17 pushes the first push plate 16 to move to push the metal column, it ensures that the stroke path of the first push plate 16 is not blocked by the support platform 19 to avoid interference.

[0048] The cylinder body of the first push cylinder 17 is fixed to the top of the fixing plate by screws. The fixing plate is fixed to the top of the base plate 2 by screws. The fixing plate supports the first push cylinder 17 and prevents its piston rod from tilting when the first push cylinder 17 is working (a commercially available linear cylinder can be used for the first push cylinder 17). The piston rod of the first push cylinder 17 is connected to the first push plate 16. The first push cylinder 17 pushes the first push plate 16 to move, thereby pushing the metal column.

[0049] The pusher post 18 is fixed to the bottom of the first push plate 16 by welding, and the length of the pusher post 18 is equal to the width of the first push plate 16. For example... Figure 6 As shown, the diameter of the push column 18 is smaller than the diameter of the bearing groove 20. Therefore, when the push column 18 and the first push plate 16 push the metal column forward together, the push column 18 will avoid the position of the bearing groove 20 and avoid interference with the bearing groove 20.

[0050] like Figure 7 The diagram shows the structure of the press-fit assembly, which includes mounting blocks 3, metal column grooves 4, first clearance grooves 5, rubber grooves 6, second clearance grooves 7, lifting cylinders 8, lifting grooves 9, top plates 10, top blocks 11, and top grooves 12. There are two mounting blocks 3, which are fixed to the top of the base plate 2 with screws and are spaced apart. A gap is left between the two mounting blocks 3 to facilitate the top block 11 to push out the assembled finished product.

[0051] The metal column groove 4 horizontally penetrates the mounting block 3, and the diameter of the metal column groove 4 is equal to the diameter of the metal column. The metal column groove 4 is coaxially arranged with the bearing groove 20 of the bearing platform 19, ensuring that the first push plate 16 and the push column 18 push the metal column in the bearing groove 20 into the metal column groove 4. The first clearance groove 5 is opened at the top of the mounting block 3 and communicates with the metal column groove 4. The width of the first clearance groove 5 is equal to the diameter of the metal column groove 4, ensuring that the top block 11 can push the metal column upward.

[0052] A rubber groove 6 is formed within the mounting block 3 and coaxially aligned with the metal column groove 4. The diameter of the rubber groove 6 is equal to the diameter of the rubber wheel, and the width of the rubber groove 6 is equal to the thickness of the rubber wheel. During actual assembly, the operator places the rubber wheel into the rubber groove 6 beforehand. A second clearance groove 7 is formed on the top of the mounting block 3 and communicates with the rubber groove 6. The width of the second clearance groove 7 is equal to the diameter of the rubber groove 6, ensuring that the top block 11 can push the rubber wheel on the metal column upwards simultaneously with the metal column.

[0053] The lifting groove 9 vertically penetrates the base plate 2. The cylinder body of the lifting cylinder 8 is fixed to the bottom of the base plate 2, and the piston rod of the lifting cylinder 8 passes through the lifting groove 9. The top plate 10 is fixed to the piston rod of the lifting cylinder 8. The lifting cylinder 8 drives the top plate 10 to rise and fall. The length of the top plate 10 is less than the length of the lifting groove 9, the width of the top plate 10 is less than the width of the lifting groove 9, and the height of the top plate 10 is less than the depth of the lifting groove 9. Therefore, when assembling the metal column and the rubber wheel, the top plate 10 and the top block 11 are placed in the lifting groove 9, which will not affect the insertion action of the metal column.

[0054] The top block 11 is fixed to the top of the top plate 10 by welding. The top groove 12 is opened on the top of the top block 11 and is "V" shaped. After the metal column and rubber wheel are assembled, the lifting cylinder 8 drives the top plate 10 and the top block 11 to rise, thereby pushing out the finished product, which is then removed by the operator.

[0055] The assembly structure of this utility model of rubber wheel and metal column uses a feeding component to guide the metal column to ensure that one side of the metal column is flush. Then, the transfer component clamps the guided metal column and places it on the bearing groove 20 of the pushing component. The first push plate 16 and the push column 18 push the metal column forward into the rubber wheel of the mounting block 3. The assembly of the metal column and the rubber wheel is completed when the first push plate 16 contacts the side of the mounting block 3. Finally, the top block 11 pushes out the finished product.

[0056] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
