Description

Technical Field

[0001] This article belongs to the technical field of parallel robot assembly tooling, and specifically relates to a tooling component applicable to a parallel robot assembly line. Background Art

[0002] With the continuous improvement of the requirements for production efficiency and quality of products in fields such as electronics, food, and medicine, higher requirements are put forward for the automated transfer equipment on the product production line. The three-plus-one-axis parallel robot is an important form of automated transfer equipment, which can pick up and classify products at high speed, smoothly, and cleanly between different production lines. This kind of robot requires three translational degrees of freedom to realize the transfer of products in space, and at the same time, it should also have a rotational degree of freedom to realize the picking up of products in different postures.

[0003] In the production and assembly process of parallel robots, especially during the motor installation process, the steel fixed disk needs to be repeatedly flipped and moved to complete the installation of the drive components. Since both the fixed disk and the drive components are relatively heavy. During the assembly process, the time consumed for flipping and rotating these components occupies more than half of the total working hours. If the assembly station is electrified, due to the high degree of customization, it cannot be compatible with the assembly of multiple different specifications of parallel robots. And if a large number of transformations are carried out, the cost is too high and the cost performance is not high. Summary of the Invention

[0004] To solve the above problems, this article proposes a tooling component applicable to a parallel robot assembly line. A lifting mechanism and a rotating mechanism are provided above the assembly table component. The assembly table component includes an assembly tabletop, a linear slide rail, a slider, and a fixed heightening block. A linear slide rail is horizontally provided below one side of the fixed heightening block. A slider is provided above the linear slide rail. A lifting mechanism is provided above the slider. A rotating mechanism is provided above the fixed heightening block. The lifting mechanism includes a lifting frame, a screw jack, and a lifting bracket. The bottom of the lifting frame is connected to the slider. A screw jack is provided in the middle of the lifting frame. The top of the screw jack is connected to the lifting bracket. The lifting bracket is arranged between the lifting frames and faces the rotating mechanism. The rotating mechanism includes a rotating disk, a rotating fixed seat, a rotating drive mechanism, and a spring pin. The upper part of the rotating disk is connected to the fixed disk component. The lower part of the rotating disk is connected to the rotating drive mechanism. The rotating drive mechanism is arranged inside the rotating fixed seat. A spring pin is penetrated through the outside of the rotating fixed seat. One end of the outside of the spring pin is connected to the lifting mechanism through a rope. One end of the inside of the spring pin is connected to the rotating drive mechanism. By the combined use of the rotating support component and the motor lifting component, the assembly process becomes easy to operate. Align the assembled motor reducer component with the motor mounting holes on the fixed disk fixed on the rotating support component through the motor lifting component.

[0005] The shape of the assembled desktop is a horizontally rectangular table. A fixed heightening block is provided at the horizontal center on the right side of the surface of the assembled desktop. A linear slide rail is horizontally provided below the left side of the fixed heightening block. The linear slide rail is a double-groove slide rail that is horizontally parallel to each other.

[0006] The lifting frame includes a lifting mechanism upper plate, a lifting mechanism fixing plate and an optical axis. The lifting mechanism fixing plate has the same shape as the lifting mechanism upper plate. The lifting mechanism fixing plate and the lifting mechanism upper plate are arranged parallel to each other up and down. An optical axis is provided between the lifting mechanism fixing plate and the lifting mechanism upper plate. The optical axis is provided at both ends between the lifting mechanism fixing plate and the lifting mechanism upper plate. A screw jack is vertically provided in the middle of the top surface of the lifting mechanism fixing plate. A lifting bracket is provided between the optical axes.

A heightening pad is provided at the top of the end of the reducer side support arm. A driving component is provided above between the reducer side support arm and the motor side support arm. Both the reducer side support arm and the motor side support arm face the rotating mechanism. The screw jack is vertically provided at the center of the top surface of the lifting machine fixing plate. A handwheel is provided outside the bottom of the screw jack. A worm is provided in the middle of the screw jack. The top of the worm is connected to the center of the lifting mechanism upper plate through a worm fixing bearing. The fixed disk is propped up through the rotating support component. Then the assembled driving component is placed on the lifting component. The fixing hole positions of the two are aligned. Rotating the handwheel of the lifting component can send the driving component to the installation position. Then tighten the fixing screws.

[0007] The bottom of the rotary fixing base is provided with a fixing base plate, and a circular sleeve is provided in the middle of the rotary fixing base.

Heavy-duty universal balls are arranged between the bottom surface of the rotary disk and the top surface of the rotary fixing base. The top surface of the rotary disk is connected to a fixed disk assembly. A lifting mechanism is vertically arranged below the fixed disk assembly. And after installing one driving component, rotating the component connected to the upper part of the rotary support component and the fixed disk can convert the installation position of the fixed disk driving component to carry out the installation work of the next motor. Thereby reducing the working intensity of the assembly workers, simplifying the assembly process and making the assembly process easier to operate.

[0008] Beneficial effects:

[0009] The cooperation of the rotary support component and the motor lifting component makes the assembly process easy to operate. The assembled motor reducer component is aligned with the motor mounting holes on the fixed disk fixed on the rotary support component through the motor lifting component.

[0010] Only by tightening the locking screws can the installation work of one driving motor be completed. After installing one motor reducer component, by rotating the upper connecting part of the rotary support component, the installation position can be converted to carry out the installation work of the next motor. Effectively solving the problem that the assembly of the fixed disk component is time-consuming and laborious.

[0011] The fixed disk is supported by the rotary support component. Then, the assembled driving component is placed on the lifting component, and the fixing holes of the two are aligned. Rotating the handwheel of the lifting component can send the driving component to the installation position, and then tighten the fixing screws.

[0012] After installing one driving component, rotating the component connected to the upper part of the rotary support component and the fixed disk can convert the installation position of the fixed disk driving component to carry out the installation work of the next motor. Thereby reducing the working intensity of the assembly workers, simplifying the assembly process and making the assembly process easier to operate. Description of the drawings
