Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a rotor insulation end plate implantation tooling. Background Technology

[0002] In the manufacturing of motor rotors for automotive parts, traditional insulation treatment mainly employs coating processes. This process has significant drawbacks: First, the coating materials typically contain volatile organic compounds, which pollute the environment during the curing process. Second, the cured coating is brittle and lacks toughness; under subsequent use or thermal stress, the insulation coating is prone to cracking or peeling, affecting product reliability. Furthermore, the entire coating process requires high-temperature environments, and the associated baking and curing equipment is expensive, resulting in long production cycles and overall low efficiency and high costs.

[0003] To address these issues, the industry has begun using prefabricated plastic insulating end plates to replace the coating. This method is more environmentally friendly and can shorten the production cycle. However, the traditional rigid installation method has significant drawbacks in the assembly process of embedding the insulating end plates: typically, only one end of the rotor (upper or lower) can be pressed in at a time, requiring two operations to complete, which is inefficient; more importantly, during pressing, due to the lack of effective floating buffer and centering positioning, rigid pressure can easily cause the plastic end plates to deform, crack, or be improperly installed, resulting in a low product yield. Once the installation is not up to standard, the rework and repair process is very troublesome, which not only increases production costs but also poses a risk to the long-term quality stability of the product. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a rotor insulation end plate implantation fixture. Through innovative floating buffer, precision positioning and integrated press-fit design, it fundamentally solves the problems of low efficiency, low yield and high quality risk of traditional assembly methods, and realizes high efficiency, high quality and safety of rotor insulation end plate assembly.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a rotor insulation end plate implantation fixture, comprising a base, wherein a floating positioning mechanism and a pressing mechanism are provided on the base; the floating positioning mechanism comprises a base plate and a floating plate; the base plate is disposed on the base and is connected to the floating plate above it by a spring; the floating plate is used to place the rotor body and the insulation end plate at the lower end of the rotor body; the base plate is provided with a first positioning hole for the rotor body shaft to be inserted, and a plurality of positioning posts are provided around the positioning hole, wherein the upper end of the positioning post penetrates the floating plate and is used to position the insulation end plate at the lower end of the rotor body; the pressing mechanism is used to apply pressure to the insulation end plate at the upper end of the rotor body, thereby implanting the two insulation end plates into the rotor body.

[0006] A further improvement is that the positioning column has a triangular cross-section, and the base plate is provided with a mounting seat for installing the spring.

[0007] A further improvement is that the base plate is provided with a first guide pin and a second guide pin for guiding the floating plate, and the first guide pin and the second guide pin have different cross-sectional shapes.

[0008] A further improvement is that the floating plate has a first through hole for the rotor body shaft to pass through, several second through holes for the positioning pins to pass through, a third through hole for the first guide pin to pass through, and a fourth through hole for the second guide pin to pass through.

[0009] A further improvement is that the floating plate is provided with several limiting posts for limiting the sides of the rotor body.

[0010] Further improvements include: two tracks are arranged opposite each other on the base, and sliding grooves adapted to the tracks are respectively provided on both sides of the base plate; mounting blocks are respectively provided at both ends of the tracks, and the mounting blocks are provided with mounting holes for installing limit blocks to limit the base plate; an adjustment plate is provided on the outer side of the tracks, and the adjustment plate is provided with adjustment grooves for adjusting the distance between the two tracks.

[0011] A further improvement is that the pressing mechanism includes a pressing cylinder, the lower end of which is provided with an expansion part, the bottom surface of which is a pressing surface, and the bottom surface of which is provided with a second positioning hole for the rotor body shaft to be inserted.

[0012] A further improvement is that it also includes a drive mechanism, which is a pneumatic cylinder or a hydraulic cylinder, and the piston rod of the drive mechanism is threadedly connected to the upper end of the lower pressure cylinder. A magnetic induction switch is provided on the cylinder body of the drive mechanism to sense whether the piston rod is pushed down or retracted.

[0013] A further improvement is that the base includes a base plate, the base plate is provided with a dovetail groove for mounting an external guide rail and a support for mounting a drive mechanism, and the support is provided with a control valve for controlling the drive mechanism.

[0014] A further improvement is that a safety protection mechanism is provided on the base, the safety protection mechanism including a grating support and a safety grating set on the grating support.

[0015] The beneficial effects of this invention are as follows: 1. This invention, through the integrated floating positioning mechanism and pressing mechanism, can simultaneously complete the implantation of the insulating end plates at both ends of the rotor, combining two operations into one, and greatly improving assembly efficiency.

[0016] 2. In this invention, the floating positioning mechanism connects the base plate and the floating plate via springs, providing cushioning during the pressing process and avoiding rigid impacts. Guide pins ensure smooth movement of the floating plate, and together with limiting posts constrain the rotor side, ensuring uniform force on the insulating end plate during pressing, effectively preventing deformation and damage to the end plate, thereby significantly improving the first-time assembly pass rate of the product.

[0017] 3. In this invention, up to 12 triangular-section positioning pins penetrate the floating plate and precisely mate with corresponding holes on the insulating end plate to ensure absolutely accurate circumferential installation angles between the end plate and the rotor core. The first positioning hole on the base plate and the second positioning hole on the pressing mechanism together position the rotor shaft, ensuring the coaxiality of the upper and lower end plates with the rotor. This multi-positioning system ensures a high degree of consistency in the assembly quality of all products.

[0018] 4. In this invention, the base plate is mounted on two adjustable tracks via a sliding groove. The track spacing can be easily adjusted using an adjustment plate to accommodate base plates of different sizes (i.e., different models of rotors). Limiting blocks at both ends of the tracks can precisely position the base plate's travel, making tooling adjustment and changeover processes quick and convenient.

[0019] 5. In this invention, the pressing mechanism can be driven by a pneumatic or hydraulic cylinder and equipped with a magnetic induction switch for stroke control, making it easy to achieve automated production. The safety light curtain protection mechanism installed on the base can stop the machine in time when the operator's hand enters the danger zone, thus improving production efficiency while fully protecting the personal safety of the operator.
