Description

Technical Field

[0001] This invention relates to the field of elevator guide rail processing technology, and in particular to an automated mechanism for drilling and grinding elevator guide rails. Background Technology

[0002] In the elevator manufacturing industry, guide rails are a core component that ensures the smooth operation of the elevator car, and their machining precision directly affects the elevator's operational safety and comfort. Among these processes, the drilling and grinding of the guide rails are crucial steps that determine their assembly precision and service life. Currently, high-precision production lines are widely used in elevator guide rail processing. However, traditional equipment occupies too much space in the horizontal direction to meet the support requirements of long guide rails, which not only increases the difficulty of factory layout but also limits the compact design of production lines.

[0003] Small elevator manufacturers and parts processing enterprises generally face the dilemma of limited funds and small production space, making it difficult to afford the high purchase cost of large production lines, and also unable to provide sufficient installation and operating space. Traditional large processing equipment not only requires large initial investment and high daily maintenance costs, but its huge size also makes it difficult to achieve a reasonable layout in limited space, which seriously restricts the production flexibility and market competitiveness of small enterprises. Summary of the Invention

[0004] To address the above problems, this invention proposes an automated mechanism for drilling and grinding elevator guide rails. The technical solution used is as follows: An automated mechanism for drilling and grinding elevator guide rails includes a support frame, as well as a feeding device, a support device, and a drilling device mounted on the support frame. The feeding device includes a feeding frame fixedly installed on a support frame. The feeding frame is provided with several intersecting movable chutes. Both ends of the movable chutes are rotatably mounted with drive wheels, and a grinding wheel is rotatably mounted at the entrance of the movable chutes. The support device includes a rotating frame rotatably mounted on a support frame, a mounting frame fixedly mounted on the rotating frame, a rotating sleeve rotatably mounted on the mounting frame, a telescopic rod slidably mounted inside the rotating sleeve, a sliding frame slidably mounted on the rotating frame, a lifting frame slidably mounted on the rotating frame, a linkage plate slidably mounted on the sliding frame and slidably connected to the lifting frame, and a connecting rod rotatably mounted at both ends on the telescopic rod and the linkage plate, respectively. The drilling device includes a drilling machine capable of moving in three axial directions.

[0005] Furthermore, the drive wheel is driven to rotate by a drive wheel mounted on the feeding rack.

[0006] Furthermore, the grinding wheel is driven to rotate by a grinding motor mounted on the feeding frame.

[0007] Furthermore, proximity sensors are installed at both ends of the movable chute.

[0008] Furthermore, the rotating frame is driven to rotate by a rotation drive device; the rotation drive device includes a rotation motor mounted on a support frame, an input gear coaxially fixedly mounted on the output end of the rotation motor, and an output gear ring fixedly mounted on the rotating frame and meshing with the input gear.

[0009] Furthermore, the rotating sleeve is rotatably mounted on the mounting frame via a rotating shaft fixedly mounted at the bottom, and is driven to rotate by a second rotating drive device. The second rotating drive device includes a second rotating motor mounted on the mounting frame, a second input gear coaxially fixedly mounted on the output end of the second rotating motor, a transition rack slidably mounted on the mounting frame and meshing with the second input gear, and an output gear fixedly mounted on the rotating shaft of the rotating sleeve and meshing with the transition rack.

[0010] Furthermore, the sliding frame is moved by a horizontal drive screw mounted on the rotating frame.

[0011] Furthermore, the lifting frame is moved by a lifting drive screw mounted on a rotating frame.

[0012] Furthermore, a support rod is fixedly installed on the outermost end of the telescopic rod.

[0013] Furthermore, the drilling device also includes a fixed frame fixedly mounted on the support frame, a movable frame slidably mounted on the fixed frame, a movable drive screw mounted on the fixed frame and used to drive the movable frame to move, a sliding mounting block slidably mounted on the movable frame, a drive cylinder mounted on the movable frame and used to drive the sliding mounting block to move, and a lifting cylinder mounted on the sliding mounting block and used to drive the drilling machine to move.

[0014] Because the present invention adopts the above-described technical solution, the present invention has the following advantages: 1. The feeding device of the present invention adopts a two-way feeding and discharging design. When one direction is finishing up, the other direction can start feeding simultaneously, which avoids the problem of traditional equipment occupying too much space in the horizontal direction. It is especially suitable for small enterprises with limited factory space, reducing the requirements for the site and improving the effective utilization rate of the site.

[0015] 2. The feeding device of the present invention is equipped with a grinding wheel. When the guide rail moves, it passes through the grinding wheel to complete the grinding, realizing a smooth connection between the drilling and grinding processes, eliminating additional transfer and adjustment steps, reducing processing time and corresponding costs, further reducing costs, and making it more in line with the economic affordability of small enterprises.

[0016] 3. The support device of the present invention can support the elevator guide rail during the processing, avoid the shaking of the guide rail during the feeding process, and ensure processing accuracy and stability. Attached Figure Description

Both ends of the movable chute 2011 are rotatably mounted with drive wheels 202, which are driven to rotate by drive wheels 202 mounted on the feeding rack 201. The drive wheels 202 can be rubber wheels. After the elevator guide rail enters the movable chute 2011, the drive wheels 202 contact the top surface of the elevator guide rail. The rotation of the drive wheels 202 can drive the elevator guide rail to move along the movable chute 2011. A grinding wheel 205 is rotatably installed at the entrance of the movable chute 2011. The grinding wheel 205 is driven to rotate by a grinding motor 206 installed on the feeding frame 201.

The rotating sleeve 304 is provided with a clearance groove corresponding to the rotating shaft on the telescopic rod 306.

[0037] The movement principle of support device 3: When support device 3 extends, the rotation drive device 305 drives the rotating sleeve 304 to rotate, the horizontal drive screw 308 drives the sliding frame 307 to move, and the lifting drive screw 311 drives the lifting frame 310 to move upward, the linkage plate 309 to move upward, and at the same time the connecting rod 312 drives the telescopic rod 306 to extend out of the rotating sleeve 304. Figure 9 The posture shown transforms into Figure 10As shown, a stable triangular structure is formed, with the support rod 3061 at the top of the telescopic rod 306 supporting the elevator guide rail; the rotation drive device 302 drives the rotating frame 301 to rotate, causing the entire support device 3 to change direction.

[0038] like Figure 1 and Figure 13 As shown, the drilling device 4 includes a fixed frame 401, a movable frame 402, a movable drive screw 403, a sliding mounting block 404, a drive cylinder 405, a lifting cylinder 406, and a drilling machine 407.

[0039] The working steps of this embodiment are as follows: The first step is to place the two elevator guide rails at the entrances of the two movable slides 2011 respectively. The proximity sensor 204 at the entrance confirms the position of the elevator guide rails, and the drive wheel 202 at the entrance clamps the elevator guide rails. The second step involves activating the drive motor 203 and grinding motor 206 at the entrance of one of the movable slideways 2011. Simultaneously, the support device 3 extends to support the elevator guide rail within the movable slideway 2011 (e.g., Figures 3-4 When the support device 3 is extended (as shown), the elevator guide rail in the movable slide 2011 begins to move, and the grinding wheel 205 performs grinding; when the elevator guide rail moves to the proximity sensor 204 at the end of the movable slide 2011, the elevator guide rail stops moving. The third step involves starting the moving drive screw 403 and drive cylinder 405, moving the drilling machine 407 to the corresponding drilling position; starting the lifting cylinder 406 and drilling machine 407, the drilling machine 407 moves downward and drills a hole in the elevator guide rail; after drilling is completed, the drilling machine 407 moves upward, the elevator guide rail continues to move, so that the next drilling point moves below the drilling machine 407, and the drilling machine 407 continues to drill. Fourth step: When the elevator guide rail moves to the position of being centrally located on the moving slide 2011, the support device 3 retracts and rotates 180° before extending to support the other side of the elevator guide rail; then the elevator guide rail continues to move, and the hole-making machine 407 continues to make holes until the holes on the elevator guide rail are finished. Fifth step: Remove the elevator guide rail that has been processed in the fourth step, start the drive motor 203 and grinding motor 206 at the entrance of another moving slide 2011 to perform the drilling work on the elevator guide rail in the moving slide 2011; place an elevator guide rail to be processed on the empty moving slide 2011, and wait for the next round of drilling processing.
