Description

Technical Field

[0001] The invention relates to the technical field of automated production equipment for elevator guide rails, and in particular to a punching device for elevator rail processing. Background Art

[0002] The elevator rail is an elevator component composed of a steel rail and a connecting plate, which is divided into a car guide rail and a counterweight guide rail. The guide rail plays a guiding role and also bears the impact force of the car and elevator during braking and the impact force of the safety clamp during emergency braking. In order to install the elevator guide rail, holes are set at both ends of the elevator guide rail. The existing hole processing is realized by manual methods, including drilling and chamfering. This method is not only labor-intensive, but also has poor dimensional stability, which affects product quality and is prone to missed processing.

[0003] In the invention patent with the publication number CN110842248A, an automatic drilling machine for elevator guide rails is proposed. In the invention, due to the structural characteristics of the elevator guide rails, it is determined that transporting them through the T-shaped top plane can obtain better stability and is more convenient. When the drill bit collides with the elevator guide rail, it is turned over to provide a flat surface without protruding structures for the processing device to process. During the processing, the clamping device effectively ensures the accuracy of positioning. However, when symmetrically drilling holes on the elevator rail, the position of the processing device needs to be repeatedly adjusted, which reduces the drilling efficiency. In addition, in the process of adjusting the position of the processing device, it is easy to affect the accuracy of drilling, which reduces the product quality of the elevator rail.

[0025] (III) Beneficial effects

[0027] In the present invention, the elevator rail is clamped and conveyed by a clamping mechanism, and the conveying process is more stable and simpler. Then, in the process of punching the elevator rail, the plane of the elevator rail is facing upward, which facilitates the punching mechanism to perform accurate punching on the elevator rail. In the process of processing, the elevator rail is fixed and limited by a supporting mechanism. Finally, the elevator rail after the punching process is sent to the inside of the discharge mechanism by the clamping mechanism, completing the fully automated production of feeding, punching and discharging of the elevator rail, and effectively improving the production efficiency and product quality of the elevator rail.

[0028] The present invention provides a support mechanism inside the mounting frame, and uses the support frame in the support mechanism to clamp and limit the elevator rail. The tops of the two support frames are in contact with the two sides of the bottom of the elevator rail, and one side of the two support frames clamps and limits the two sides of the elevator rail.

The working principle of the punching equipment used for elevator rail processing includes the following steps: The first step is to place the elevator rail into the frame (10), and use two electric push rods (106) to push the clamping plate (102) close to one side of the elevator rail. One side of the elevator rail slides into the clamping groove inside the clamping plate (102), and cooperates with the two limit plates (103) inside the clamping plate (102) to complete the clamping of the elevator rail. Step 2: The conveyor belt (40) conveys the clamping mechanism, and the elevator rail is driven by the clamping mechanism to slide into the interior of the mounting frame (20); Step 3: The two servo electric cylinders 1 (205) push the two support frames (206) upward until the tops of the two support frames (206) contact the two sides of the bottom of the elevator track. The two servo motors 3 (209) drive the two first screws (202) to rotate, so that the two support frames (206) are close to each other. One side of the two support frames (206) clamps and limits the two sides of the elevator track. The two electric push rods 2 (208) respectively push the two positioning plates (207) to position the two sides of the elevator track. At the same time, the two electric push rods 3 (213) respectively push the two limit blocks (214) to approach the elevator track, and clamp and limit the two sides below the elevator track through the limit grooves (215) inside the two limit blocks (214); Step 4: The linear motor (310) drives the two fixed frames (311) to slide, and adjusts the position between the punching mechanism and the elevator track. Then, the movable frame (301) is pushed downward by the two servo electric cylinders (313). The servo motor (309) drives the second screw (302) to rotate. During the rotation of the second screw (302), the positions of the two second movable blocks (303) are adjusted. The second movable blocks (303) are used to control and adjust the position of the punching. After adjusting the relative distance between the two second movable blocks (303), the first drill bit (307) is used to punch the elevator track. Then, the second drill bit (308) is replaced to punch the elevator track. Step 5. After the elevator rail is punched, two clamping mechanisms send the elevator rail in the support mechanism to the top of the discharge rack (30), and use two cylinders to push the discharge table (402) upward. The discharge table (402) is used to place the punched elevator rail, and finally the discharge table (402) is sent to the next processing step through the discharge rack (30), completing the fully automatic punching of the elevator rail.
