Description

[Technical Field]

[0001] This utility model mainly relates to a caster spring clip assembly machine. [Background Technology]

[0002] Traditional caster assembly relies primarily on manual labor. Operators must use specialized tools, such as snap ring pliers, to install each component one by one, with snap ring installation requiring particular skill. This manual assembly method has significant drawbacks: First, it is inefficient, heavily dependent on worker skill, and cannot meet the demands of large-scale production. Second, manual assembly is prone to errors and omissions, especially if snap rings are not fully in place, which will seriously affect the quality and safety of the caster. Third, manual assembly is labor-intensive, costly, and has a high rework rate.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] The preferred embodiment provided by this utility model is as follows: Figures 1-5 As shown, a caster spring clip assembly machine includes a positioning mechanism 1, a pushing mechanism 2, and a guiding mechanism 3. The pushing mechanism 2 and the guiding mechanism 3 are respectively located on both sides of the positioning mechanism 1, and the pushing mechanism 2 and the guiding mechanism 3 are located on the same horizontal plane. A motor 11 is provided adjacent to the positioning mechanism 1, and an abutment rod 12 is provided at the rotating end of the motor 11. The abutment rod 12 is driven by the motor 11 and is movably connected to the shaft core 41 of the caster 4.

[0027] The pushing mechanism 2 includes a pushing platform 21, a push rod 22, a spring-loaded material dropping part 23, a pressing member 24, a lifting cylinder 25, and a first translation cylinder 26. The pushing platform 21 has a material groove 27 that extends through both ends of the pushing platform 21 to facilitate pushing materials. The push rod 22 extends into the material groove 27. The first translation cylinder 26 is connected to the push rod 22 to drive the push rod 22 to move along the material groove 27. The spring-loaded material dropping part 23 has a through hole 28 that communicates with the material groove 27. The pressing member 24 is located above the through hole 28.

[0028] The guiding mechanism 3 includes a guide member 31 and a second translation cylinder 32. The second translation cylinder 32 is connected to the guide member 31 to drive the guide member 31 through the caster 4 and into the material trough 27. The guide member 31 extends horizontally out of the pressing part 33. After the spring 47 is pressed down, the gap of the spring 47 is reduced. The thickness of the pressing part 33 should be set to be thin to facilitate insertion into the gap of the spring 47.

[0029] The positioning mechanism 1 has a cavity 13 for placing the caster 4. The positioning mechanism 1 includes a plug-in seat 14 and a push cylinder 15. The plug-in seat 14 has a clamp 16 for placing the shaft card 5. The push cylinder 15 is connected to drive the plug-in seat 14 so that the shaft card 5 is engaged with the shaft core 41 of the caster 4.

[0030] The connector 14 includes a first connector 141 and a second connector 142. The propulsion cylinder 15 includes a first propulsion cylinder 151 and a second propulsion cylinder 152. The first propulsion cylinder 151 is connected to the first connector 141, and the second propulsion cylinder 152 is connected to the second connector 142. The piston rods of the first propulsion cylinder 151 and the second propulsion cylinder 152 face opposite directions to control the clamping state formed by the cooperation of the first connector 141 and the second connector 142. Each cylinder adopts an existing cylinder structure, only the arrangement creates different directional requirements.

[0031] The top of the first connector 141 is provided with a slot 143, and the top of the second connector 142 is provided with a locking position 144. The slot 143 and the locking position 144 are connected to form a clamp 16. The slot 143 is a recess located at the top of the first connector 141, and the locking position 144 is an inclined surface at the top of the second connector 142 to accommodate the L-shaped shaft card 5.

[0032] The bottom end of the caster 4 has a cavity 42 for the insertion of the connector 14. The axle core 41 of the caster 4 has an annular groove 43, and the axle clip 5 has a U-shaped opening 53. The U-shaped opening 53 is connected to the annular groove 43 to secure the axle clip 5 to the axle core 41. The caster 4 has a through cavity 45 that extends through both sides of the caster 4. A support plate 46 is placed in the material groove 27, and a spring 47 is placed in the spring drop section 23. The spring 47 is connected to the support plate 46 and is pushed into the through cavity 45 together by the push rod 22.

[0033] Operating procedure: Place the shaft clip 5 in the slot 144 of the second connector 142. The second push cylinder 152 pushes the second connector 142 to move, and the first connector 141 approaches the second connector 142, so that the slot 143 engages with the slot 144 to form a clamp 16, thus fixing the shaft clip 5. Place the caster 4 into the cavity 13, so that the connector 14 enters the bottom cavity 42 of the caster 4. The motor 11 rotates and the abutment rod 12 abuts against the shaft core 41 of the caster 4, restricting the position of the caster 4. The first push cylinder 151 pushes the connector 14 to move, and the shaft clip 5 is engaged in the annular groove 43 of the shaft core 41 of the caster 4. The support plate 46 is placed in the material trough 27 and located below the spring dropping part 23. The spring 47 is inserted into the through hole 28 of the spring dropping part 23. The lifting cylinder 25 drives the pressing part 24 to move down and insert into the through hole 28, pressing the spring 47 in the through hole 28 against the support plate and compressing it. At the same time, the second translation cylinder 32 drives the guide part 31 to pass through the through cavity 45 and caster 4. The pressing part 33 is inserted into the compressed spring 47, keeping the spring 47 in a compressed state. The first translation cylinder 26 drives the push rod 22 to move and connect with the support plate. The push rod 22 and the guide part 31 move at the same time, sending the support plate and the spring 47 into the through cavity 45 at the same time. After the spring 47 is separated from the pressing part 24, it returns to its original state and presses against the wall of the through cavity 45 to prevent it from falling out.
