At the same time, the assembly efficiency is low, which can easily lead to many negative impacts such as delivery delays. Utility Model Content

[0003] This utility model discloses a rubber ring installation machine, which aims to improve the problems of low assembly efficiency and easy wear and tear on the fingers of operators in the existing rubber ring assembly.

[0004] The present invention adopts the following solution:

[0005] A rubber ring installation machine for assembling rubber rings onto a shaft includes a machine base and a feeding mechanism and an installation mechanism disposed on the machine base. The feeding mechanism has a collecting pipe for placing the rubber ring, a feeding groove located at the discharge end of the collecting pipe, and a driving member for pushing the rubber ring along the feeding groove. The installation mechanism has a receiving groove communicating with the feeding groove, a positioning member located above the receiving groove, and a push rod for pushing the rubber ring from the receiving groove to the top of the positioning member. The positioning member is provided with a material passage, and the push rod is provided with an expansion portion. The expansion portion cooperates with the material passage to open the opening of the rubber ring, allowing the shaft to be smoothly inserted into the rubber ring.

[0006] As a further improvement, the positioning element includes a housing and a plurality of positioning blocks for enclosing the material passage. An elastic element is abutted between the positioning block and the housing. When the push rod pushes the rubber ring to move upward along the material passage, it causes the positioning block to overcome the elastic force of the elastic element and move outward.

[0007] As a further improvement, the positioning block is provided with a first mounting hole, the outer shell is sleeved on the outside of the positioning block, and a second mounting hole is provided opposite the first mounting hole. A screw is disposed in the second mounting hole, and the elastic element is sleeved on the screw and abuts against the first mounting hole.

[0008] As a further improvement, the mounting mechanism includes a fixed base fixed to the machine table surface, the receiving groove is disposed on the fixed base, and the positioning block is connected to the fixed base via a movable component.

[0009] As a further improvement, the positioning block is provided with a horizontal portion, and the moving component includes a slider for connecting to the horizontal portion and a guide rail for connecting to the fixed base. The slider is adapted to the guide rail so that the positioning block can move along the extension direction of the guide rail.

[0010] As a further improvement, a limit block is provided at the end of the receiving trough away from the feeding trough.

[0011] As a further improvement, the material passage is configured such that the cross-sectional dimensions decrease progressively from bottom to top.

[0012] As a further improvement, the push rod is driven to move by a push cylinder, and the top of the push rod is provided with a limiting part whose size is smaller than the inner hole size of the rubber ring. The bulging part is located near the limiting part and its size is larger than the inner hole size of the rubber ring.

[0013] As a further improvement, the driving component includes a movable cylinder and a top block connected to the movable cylinder. The top block is disposed in the feeding groove and is used to push one end of the rubber ring, which has an arc-shaped surface similar to the outer wall of the rubber ring.

[0014] As a further improvement, a window is provided on the side wall of the collecting pipe, and the window extends along the axial direction of the collecting pipe.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] 1. The automatic feeding mechanism for rubber rings and the installation mechanism opening the rubber ring opening allow the shaft to pass through smoothly, thus achieving automatic rubber ring assembly. This improves upon the low assembly efficiency and finger wear issues of existing rubber ring systems. It reduces the labor intensity of manual component assembly, transforming manual operations into automation, improving assembly efficiency, ensuring assembly quality, and reducing waiting time in product processing, thereby creating higher profits and enhancing the company's competitiveness.

[0017] 2. The design of the guide rail and slider ensures accurate and smooth movement of the positioning block.

[0018] 3. The material passage is designed with a progressively decreasing cross-sectional dimension from bottom to top, so that the rubber ring can be resisted by the material passage during its upward movement, thus achieving the expansion of the expansion section. At the same time, the lower cross-sectional dimension is larger than the maximum outer diameter of the rubber ring so that the rubber ring can smoothly enter the material passage.

[0019] 4. A limit block is provided at the end of the receiving trough away from the feeding trough to ensure that the rubber ring can be quickly positioned when it is pushed from the feeding trough to the receiving trough.

[0020] 5. The limiting part on the top rod inserts into the inner hole of the rubber ring, which limits the rubber ring radially and prevents it from shifting. The bulging part is positioned close to the limiting part to ensure the bulging effect.

[0021] 6. A window is provided on the side wall of the collecting pipe, which extends along the axial direction of the collecting pipe to allow operators to observe the condition of the rubber ring and the remaining material in the collecting pipe, so as to facilitate timely replenishment of material and reduce standby time.

The terms “first,” “second,” etc., are only used to distinguish different objects and should not be construed as indicating or implying relative importance or the quantity, specific order, or primary or secondary relationship of the indicated technical features.

[0043] Combination Figures 1 to 12 This embodiment provides a rubber ring installation machine for assembling a rubber ring A onto a shaft B1. It includes a machine base 1 and a feeding mechanism 2 and an installation mechanism 3 mounted on the machine base 1. Specifically, the feeding mechanism 2 has a collecting pipe 21 for placing the rubber ring A, a feeding groove 22 located at the material drop end of the collecting pipe 21, and a driving member 23 for pushing the rubber ring A along the feeding groove 22. The installation mechanism 3 has a receiving groove 31 communicating with the feeding groove 22, a positioning member 32 located above the receiving groove 31, and a push rod 33 for pushing the rubber ring A from the receiving groove 31 to the top of the positioning member 32. The positioning member 32 has a material passage 321, and the push rod 33 has an expansion portion 331. The expansion portion 331 cooperates with the material passage 321 to open the opening A1 of the rubber ring A, allowing the shaft B1 to be smoothly inserted into the rubber ring A.

[0044] For example, the rubber ring A is annular in shape, with an opening A1 along its side wall. When the opening A1 is open, the inner hole size of the rubber ring A increases, allowing the shaft B1 to be smoothly inserted into the rubber ring A. The shaft B1 is vertically mounted on the slotted tube B. During assembly, the nut C is first placed on the outside of the rubber ring A, and then the shaft B1 is passed through the nut C and inserted into the inner hole of the rubber ring A. At the same time, the push rod 33 is driven to retract, so that the rubber ring A returns to its initial state under its own elastic force, thereby tightly engaging with the shaft B1. This limits the nut C axially, preventing the nut C from coming off the shaft B1.

[0045] It should be noted that in this embodiment, the feeding mechanism 2 automatically feeds the rubber ring A, and the mounting mechanism 3 opens the opening A1 of the rubber ring A so that the shaft B1 can be smoothly inserted, thereby realizing the automatic assembly of the rubber ring A. This improves the problems of low assembly efficiency and easy wear and tear on the fingers of operators in the existing rubber ring A assembly. It reduces the labor intensity of manual assembly of components, realizes the transformation from manual operation to automation technology, improves assembly efficiency, ensures assembly quality, and reduces waiting time in the product processing stage, creating higher efficiency and helping to improve the competitiveness of enterprises.

[0046] In a preferred embodiment, the positioning member 32 includes a housing 323 and a plurality of positioning blocks 322 for surrounding the feed channel 321. An elastic member 324 is abutted between the positioning blocks 322 and the housing 323. When the push rod 33 pushes the rubber ring A upward along the feed channel 321, the positioning blocks 322 overcome the elastic force of the elastic member 324 and move outward. The elastic member 324 is preferably a spring. The positioning blocks 322 have a first mounting hole 3221. The housing 323 is sleeved on the outside of the positioning blocks 322 and has a second mounting hole 3231 opposite the first mounting hole 3221. A screw 325 is disposed in the second mounting hole 3231. The elastic member 324 is sleeved on the screw 325 and abuts against the first mounting hole 3221. The installation process of the rubber ring A in this embodiment is as follows:

[0047] First, the rubber rings A are placed in batches into the collecting pipe 21. The inner diameter of the collecting pipe 21 is matched with the maximum outer diameter of the rubber rings A so that the rubber rings A can be arranged sequentially along the axial direction of the collecting pipe 21, while ensuring that only one rubber ring A can fall at a time when the material is dropped.

[0048] The rubber ring A that falls into the feeding trough 22 is driven by the drive component 23 to move along the feeding trough 22 to the receiving trough 31;

[0049] The push rod 33 moves upward, pushing the rubber ring A upward. Due to the resistance of the material passage 321, the expansion part 331 opens the opening A1 of the rubber ring A. At this time, the positioning block 322 compresses the elastic element 324 to move outward. When the rubber ring A is pushed to the top of the positioning block 322, the positioning block 322 moves inward under the action of the elastic element 324.

[0050] The operator places nut C on the outside of rubber ring A, then inserts shaft B1 on slotted tube B into the inner hole of rubber ring A, applies slight downward pressure, and simultaneously drives push rod 33 to retract, so that rubber ring A springs back and opening A1 resets, thus realizing the automatic assembly function of rubber ring A.

[0051] In one embodiment, the material passage 321 is configured such that its cross-sectional dimensions decrease progressively from bottom to top. For example, the material passage 321 is funnel-shaped, and the maximum outer diameter of the rubber ring A is not less than the minimum cross-sectional dimension of the material passage 321, so that the rubber ring A is resisted by the material passage 321 during its upward movement, thereby enabling the bulging part 331 to bulge the rubber ring A. The lower cross-sectional dimension is larger than the maximum outer diameter of the rubber ring A so that the rubber ring A can enter the material passage 321, allowing the rubber ring A to move along the curved surface of the material passage 321. This is not limited to this embodiment and is not specifically limited.

[0052] Based on the above embodiments, in an optional embodiment of this utility model, the mounting mechanism 3 includes a fixed base 34 fixed to the table surface of the machine base 1, a receiving groove 31 disposed on the fixed base 34, and a positioning block 322 connected to the fixed base 34 via a moving component. Further, the positioning block 322 has a horizontal portion, and the moving component includes a slider 35 for connecting to the horizontal portion and a guide rail 36 for connecting to the fixed base 34. The slider 35 and the guide rail 36 are adapted to allow the positioning block 322 to move along the extending direction of the guide rail 36. The arrangement of the guide rail 36 and the slider 35 ensures accurate and smooth movement of the positioning block 322. It also ensures that the positioning block 322 can be reset under the action of the elastic member 324, so that the rubber ring A can still remain on the top of the positioning block 322 after the top rod 33 retracts.

[0053] Preferably, a limiting block 37 is provided at the end of the receiving groove 31 away from the feeding groove 22. The driving component 23 includes a moving cylinder 231 and a top block 232 connected to the moving cylinder 231. The top block 232 is disposed in the feeding groove 22, and its end for pushing the rubber ring A has an arc-shaped surface similar to the outer wall of the rubber ring A, so as to prevent the rubber ring A from falling out of the feeding groove 22 during movement, and play a certain limiting role. The setting of the limiting block 37 can ensure that the rubber ring A is pushed quickly and accurately along the feeding groove 22 to the receiving groove 31, realize rapid positioning, and ensure the alignment of the rubber ring A and the top rod 33.

[0054] In another embodiment, the push rod 33 is driven to move by a push cylinder 38. The top of the push rod 33 is provided with a limiting part 332, the size of which is smaller than the inner hole of the rubber ring A. The bulging part 331 is disposed near the limiting part 332, and its size is larger than the inner hole of the rubber ring A. When the push rod 33 moves upward, the limiting part 332 first inserts into the inner hole of the rubber ring A to limit the rubber ring A radially, preventing the rubber ring A from shifting. The bulging part being disposed near the limiting part 332 ensures the bulging effect.

[0055] In other embodiments, a window 211 is provided on the side wall of the collecting pipe 21. The window 211 extends along the axial direction of the collecting pipe 21 to allow operators to observe the condition of the rubber ring A and the remaining material in the collecting pipe 21, so as to facilitate timely replenishment of materials by operators and reduce standby time.

[0056] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
