Description

Technical Field

[0001] The utility model relates to the technical field of assembling a clamp spring, in particular to an automatic assembling device for a clamp spring. Background Art

[0002] The motor core is usually composed of a stator and a rotor. A rotating shaft is provided in the center of the rotor. In order to fix the core and other parts on the rotating shaft, a rotating shaft retaining spring needs to be installed. The rotating shaft retaining spring is fixed in the retaining spring groove of the rotating shaft and plays the role of fixing the baffle. At present, the installation of retaining springs has been replaced by equipment instead of manual work, achieving more efficient installation. However, since the retaining springs are installed by equipment, the retaining springs need to be loaded one by one at the feeding end, so that the retaining springs can be better installed on the motor core with the equipment. How to improve the precise control of the number of retaining springs at the feeding end to ensure that there will be no blockage in the subsequent retaining spring installation? Therefore, an automatic retaining spring assembly device is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide an automatic assembling device for a retaining spring, so as to solve the problem of conveying a single retaining spring during the assembly of retaining springs in the prior art.

[0004] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides the following technical solutions: a spring automatic assembly device, comprising a base,

[0005] A feeding platform, the feeding platform is arranged on a base platform, a slideway is arranged inside the feeding platform, and a material head with a conveying clip is slidably connected inside the slideway;

[0006] A material rod, wherein the cross section of the material rod is arranged in a pseudo-circlip shape, and the circlips are sequentially sleeved on the material rod;

[0007] A feeding rack is arranged on the base and at the rear end of the feeding platform. A feeding driving member is arranged on the feeding rack. A feeding push rod is arranged at the movable end of the feeding driving member. The feeding push rod drives the material head to slide in the slideway. The feeding push rod is arranged at an interval from the material head, and a return spring is arranged in the interval space.

[0008] To implement the above technical solution, when assembling the retaining spring, place the retaining spring on the material rod, use the material rod to guide the feeding end of the retaining spring, and convey the retaining spring to the slideway below the material rod. In the initial state, the material head is located in the slideway below the material rod. When the retaining spring falls onto the material head under the action of gravity, the feeding drive member is actuated to drive the feeding push rod at its movable end to move forward, and convey the single retaining spring along the slideway to the assembly work surface. The setting of the reset spring can enable the material head to move toward the fixed end of the feeding drive member under the external extrusion force after it moves to the front end of the feeding rack, thereby expanding the retaining spring and facilitating subsequent assembly.

[0009] In one embodiment of the utility model, a feeding end cover is provided on the upper side of the feeding platform, the feeding rod is provided on the feeding end cover, and the bottom of the feeding rod is spaced from the upper end surface of the slideway, and the spacing height is greater than the thickness of one retaining spring and less than the thickness of two retaining springs.

[0010] To implement the above technical solution, the setting of the feeding end cover can ensure the stability of the retaining spring moving with the material head in the slideway, and the interval height is set to be greater than the thickness of one retaining spring and less than the thickness of two retaining springs, which can ensure that each movement of the material head can drive a single retaining spring to move to the assembly station.

[0011] In an embodiment of the present invention, the width of the slideway is greater than the radial dimension of the retaining spring.

[0012] The above technical solution is implemented to ensure smooth sliding of the retaining spring in the slideway.

[0013] In one embodiment of the utility model, the upper end surface of the material head is lower than the height of the thickness of a retaining spring on the upper end surface of the slideway, and a triangular guide platform is provided on the material head. The rear end of the triangular guide platform is provided with a guide groove for simulating the opening of the retaining spring. When the material head is located below the material rod, the rear end of the triangular guide platform presses against the inner end surface opposite to the opening end of the retaining spring. When the feeding rack pushes the material head to move to the maximum stroke, the material head moves toward the side close to the feeding rack, and the triangular guide platform moves with the material head to open the opening end of the retaining spring along the guide groove.

[0014] To implement the above technical solution, when the material head is in the initial position, the retaining spring falls onto the material head with the material rod, and the inner end face opposite the open end of the retaining spring falls on the rear end position of the triangular guide platform. In the process of the material head sliding in the slideway with the feeding drive member, the rear end of the triangular guide platform contacts the inner end face opposite the open end of the retaining spring, and the open end of the retaining spring is stuck in the guide groove, driving the retaining spring to move with the material head. After the material head moves to the maximum stroke, the outside world supports the material head. At that time, due to the interval between the front end of the feeding push rod and the material head, and a reset spring is provided in the interval space, the material head will move toward the feeding push rod. At that time, the triangular guide platform moves with the material head in the direction of the feeding push rod, and the front end of the feeding push rod supports the rear end of the retaining spring. In the process of the triangular guide platform moving in the direction of the feeding push rod, the open end of the retaining spring will be gradually expanded, and then fall into the motor bearing. The feeding drive member performs a reset action to drive the material head back to the initial position, and the retaining spring is sleeved on the motor bearing.

[0015] In one embodiment of the present invention, the upper end surface of the feeding push rod is flush with the upper end surface of the slideway.

[0016] By implementing the above technical solution, the feeding push rod can be used to transport the retaining spring and to support the retaining spring during its expansion.

[0017] In one embodiment of the present invention, a pseudo-columnar limiting groove is provided on the front end surface of the material head.

[0018] Implementing the above technical solution facilitates the insertion of the motor bearing.

[0019] In one embodiment of the utility model, a retaining spring guide plate is provided on the material rod, and the retaining spring guide plate is extended radially out of the material rod.

[0020] To implement the above technical solution, the provision of the retaining spring guide plate can facilitate the guide and limit processing during the retaining spring feeding, thereby ensuring the loading stability of the retaining spring.

[0021] In one embodiment of the utility model, a limiting groove is provided at the front end of the push rod, and a limiting protrusion connected to the limiting groove is provided on the upper side of the material head, and the limiting protrusion and the limiting groove are detachably connected.

[0022] The above technical solution is implemented to improve the assembly adaptability between the material head and the push rod.

[0023] As described above, the utility model provides an automatic assembly device for retaining springs, which has the following beneficial effects: when assembling retaining springs, the retaining springs are placed on the material rod, and the material rod is used to guide the feeding end of the retaining springs, and the retaining springs are conveyed to the slideway below the material rod. In the initial state, the material head is located in the slideway below the material rod. When the retaining springs fall onto the material head under the action of gravity, the feeding drive member is actuated to drive the feeding push rod at its movable end to move forward, and the single retaining springs are conveyed along the slideway to the assembly work surface. The setting of the reset spring enables the material head to move toward the fixed end of the feeding drive member under the external extrusion force after it moves to the front end of the feeding rack, thereby stretching the retaining springs and facilitating subsequent assembly.
