Description

Technical Field

[0001] This utility model belongs to the technical field of elevator guide rail processing equipment, specifically relating to an elevator guide rail processing center. Background Technology

[0002] Elevator guide rails are a core safety component for elevator operation, and their machining precision directly affects the smoothness, comfort, and safety of elevator operation. One end of the elevator guide rail has a female tenon, and the other end has a male tenon. The connection between every two sections of the elevator guide rail relies on these tenons. The symmetry between the tenon and the mortise determines whether the connection of the elevator guide rail is smooth.

[0003] Traditional elevator guide rail machining equipment can only process one end of the elevator guide rail at a time. After processing one end, the elevator guide rail needs to be removed, both ends reversed, and then clamped again. This not only results in low processing efficiency but also makes it prone to errors during the two clamping processes, leading to poor machining quality. Furthermore, machining the ends of the elevator guide rail involves multiple steps such as milling, drilling, tapping, and chamfering. Each step requires manual changing of the corresponding tools, further reducing processing efficiency. Additionally, the fine powdery chips generated during processing can be suspended in the air and inhaled by workers, posing a threat to their health. Therefore, there is an urgent need to design an elevator guide rail machining center to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide an elevator guide rail processing center to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elevator guide rail machining center, comprising: The base has a strip groove at the top, an electric lifting rod at the bottom of the strip groove, corresponding positioning clamps on the side wall of the strip groove, and linear guide rails on both sides of the bottom of the base. The machining mechanism includes a machining box and a machining table, a spindle and a tool holder disposed inside the machining box. There are two machining boxes, which are respectively disposed at both ends of the base. The chip removal mechanism includes a coolant tank and a water pump fixed to the top of the machining chamber, a chip collection hopper located at the bottom of the machining table, and an air filter located at the top of the machining chamber.

[0006] Furthermore, a slider is slidably connected to the linear guide rail, one end of the linear guide rail is provided with a servo motor that provides power support for the reciprocating motion of the slider, and one end of the slider is fixed with a brake.

[0007] Furthermore, the processing box is fixed to the top of the slider, and the processing box has a feed port on the side facing the base. The size of the feed port is not less than the longitudinal cross-sectional size of the elevator guide rail to be processed.

[0008] Furthermore, the top plate of the processing table is provided with several strip-shaped through holes, and a spindle robot is provided on one side of the processing table. The spindle is rotatably connected to the top of the spindle robot in the horizontal direction. A spindle motor for driving the spindle to rotate is fixed on the spindle robot, and a laser rangefinder sensor is provided on one side of the spindle robot.

[0009] Furthermore, the tool holder is positioned between the machining table and the spindle robot. The tool holder is a disc-type tool holder. A reducer is provided on one side of the top of the tool holder, and a tool base is provided on the other side of the top, which is keyed to the output shaft of the reducer. Several tool holders are fixed around the outer edge of the tool base, and each tool holder holds and fixes a tool.

[0010] Furthermore, the water pump inlet is connected to the coolant tank, and the water pump outlet is connected to a spray pipe extending into the machining chamber. The spray pipe is fixed to the spindle robot and its opening faces the spindle.

[0011] Furthermore, the air filter has two layers, an exhaust fan between the two layers, and the air filter is an activated carbon filter.

[0012] Furthermore, it also includes a tool monitoring mechanism, which includes a power sensor located outside the spindle motor and a laser tool setter located on the top surface of the machining chamber. The laser tool setter is arranged correspondingly to the tool holder.

[0013] Furthermore, it also includes a control mechanism, which includes a control cabinet located on one side of the base, and a touch screen and control buttons are provided on one outer surface of the control cabinet.

[0014] The technical effects and advantages of this utility model are as follows: This elevator guide rail machining center features an advanced design, compact structure, ease of use, and reliable operation. Two machining chambers located at both ends of the base can simultaneously process both ends of the elevator guide rail, avoiding the need for secondary clamping required by traditional equipment. This significantly improves processing efficiency and reduces errors caused by secondary clamping, thus significantly enhancing processing quality. The disc-type tool holder, combined with the reducer and tool base, allows for convenient and quick tool changes, meeting the diverse needs of multiple processes such as milling, drilling, tapping, and chamfering of the elevator guide rail ends. This effectively avoids the inefficiency caused by manual tool changing. The chip removal mechanism, with its coolant tank and water pump working in conjunction with the spray pipe, effectively cools and lubricates the cutting tools and machining areas during processing, reducing tool wear and improving machining accuracy. It also flushes chips into the chip hopper. The combination of an air filter and exhaust fan effectively filters fine powdery chips generated during processing, preventing them from being inhaled by workers and protecting their health. The tool monitoring mechanism uses a power sensor to monitor spindle motor power changes in real time, promptly detecting abnormalities such as tool wear. A laser tool setter precisely adjusts the tool position to ensure machining accuracy. The control mechanism, via a touchscreen and control buttons, allows for convenient centralized control and parameter setting by operators, offering simple and intuitive operation. In conclusion, this elevator guide rail machining center significantly improves the processing efficiency and quality of elevator guide rails, enhances the working environment, and provides an efficient and reliable solution for elevator guide rail production.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] This utility model provides, for example Figure 1-5 The elevator guide rail machining center shown includes: The base 100 has a strip groove 101 on its top and an electric lifting rod 102 at its bottom. A corresponding positioning clamp 103 is provided on the side wall of the strip groove 101. Linear guide rails 104 are provided on both sides of the bottom of the base 100. The two ends of the strip groove 101 pass through the base 100. The length of the strip groove 101 is less than the length of the elevator guide rail to be processed. When loading is required, the electric lifting rod 102 lifts the elevator guide rail upwards and supports it, then lowers the elevator guide rail to the bottom of the strip groove 101. When unloading is required, the electric lifting rod 102 lifts the processed elevator guide rail upwards, making it easy for an RGV trolley or forklift to pick up the elevator guide rail. The positioning clamp 103 can fix the elevator guide rail in the strip groove 101 to prevent displacement of the elevator guide rail during processing. The machining mechanism 200 includes a machining box 201 and a machining table 202, a spindle 203 and a tool holder 204 disposed within the machining box 201. There are two machining boxes 201, which are respectively disposed at both ends of the base 100. The two machining boxes 201 can simultaneously process both ends of the elevator guide rail, which not only doubles the processing efficiency, but also reduces the error caused by secondary clamping and significantly improves the processing quality. The chip removal mechanism 300 includes a coolant tank 301 and a water pump 302 fixed to the top of the machining box 201, a chip collection hopper 303 located at the bottom of the machining table 202, and an air filter 304 located at the top of the machining box 201. The coolant can not only cool the cutting tool 206, but also flush larger chips generated during the machining process into the chip collection hopper 303. The air filter 304 can adsorb fine powdery chips in the machining box 201.

[0020] For example, see Figure 2 As shown, a slider 105 is slidably connected to the linear guide rail 104. One end of the linear guide rail 104 is provided with a servo motor 106 that provides power support for the reciprocating motion of the slider 105. One end of the slider 105 is fixed with a brake 107.

[0021] In this technical solution, the servo motor 106 can precisely control the reciprocating motion of the slider 105 on the linear guide rail 104, ensuring that the processing box 201 can accurately reach the designated processing position. The brake 107 will brake quickly after the slider 105 reaches the predetermined position, ensuring the stability of the processing box 201 during the processing and avoiding the impact of shaking on the processing accuracy.

[0022] For example, see Figure 1 and Figure 5As shown, the processing box 201 is fixed to the top of the slider 105. The processing box 201 has a feed port 207 on the side facing the base 100. The size of the feed port 207 is not less than the longitudinal cross-sectional size of the elevator guide rail to be processed.

[0023] In this technical solution, the feed inlet 207 allows the elevator guide rail to be processed to smoothly enter the processing box 201. After the elevator guide rail enters the processing box 201 through the feed inlet 207, the elevator guide rail will fit against the top surface of the processing table 202, and the processing table 202 can provide support for the end of the elevator guide rail.

[0024] For example, see Figure 5 As shown, the top plate of the processing table 202 is provided with several strip-shaped through holes. A spindle robot 205 is provided on one side of the processing table 202. The spindle 203 is rotatably connected to the top of the spindle robot 205 in the horizontal direction. A spindle motor 2031 for driving the spindle 203 to rotate is fixed on the spindle robot 205. A laser rangefinder sensor 208 is provided on one side of the spindle robot 205.

[0025] In this technical solution, the strip-shaped through hole on the top plate of the machining table 202 not only reduces the weight of the machining table 202, but also allows coolant and chips to pass smoothly and fall into the chip collection hopper 303 below. The spindle robot 205 can flexibly adjust the position and angle of the spindle 203 to adapt to different machining needs. The spindle motor 2031 provides powerful rotational power to the spindle 203, enabling the tool 206 to efficiently process the elevator guide rail. The laser range sensor 208 can monitor the distance between the spindle 203 and the elevator guide rail in real time, thereby accurately controlling the machining depth and position and further improving machining accuracy.

[0026] For example, see Figure 5 As shown, the tool holder 204 is located between the machining table 202 and the spindle robot 205. The tool holder 204 is a disc-type tool holder. A reducer 209 is provided on one side of the top of the tool holder 204, and a tool base 210 is provided on the other side of the top, which is keyed to the output shaft of the reducer 209. Several tool holders 211 are fixed around the outer edge of the tool base, and each tool holder 211 holds and fixes a tool 206.

[0027] In this technical solution, the reducer 209 can drive the tool base 210 to rotate, thereby rotating the required tool 206 to the designated position, which facilitates the quick connection between the spindle 203 and the required tool 206. In addition, by installing multiple different types of tools 206 on the tool holder 211, the tool 206 can be quickly changed as needed during the machining process, which can meet the different needs of multiple processes such as milling, drilling, tapping, and chamfering of elevator guide rail ends.

[0028] For example, see Figure 1 and Figure 5 As shown, the inlet of the water pump 302 is connected to the coolant tank 301, and the outlet of the water pump 302 is connected to a spray pipe 305 extending into the processing box 201. The spray pipe 305 is fixed to the spindle robot 205 and the pipe opening is set towards the spindle 203.

[0029] In this technical solution, during the processing, the water pump 302 draws coolant from the coolant tank 301 and sprays it onto the tool 206 and the processing area through the spray pipe 305. The coolant can not only reduce the temperature of the tool 206 and the processing area, reduce the wear of the tool 206, and improve the processing accuracy, but also flush the chips into the chip collection hopper 303 to keep the processing environment clean.

[0030] For example, see Figure 5 As shown, the air filter 304 has two layers, upper and lower, and an exhaust fan 306 is provided between the two layers of air filter 304. The air filter 304 is an activated carbon filter.

[0031] In this technical solution, some fine powdery chips are generated during the processing. These chips will be suspended in the air. The exhaust fan 306 draws the air containing the chips into the air filter 304. The activated carbon filter can effectively adsorb and filter these fine powdery chips, preventing them from being suspended in the air and inhaled by workers, thus protecting the health of workers.

[0032] For example, see Figure 5 As shown, it also includes a tool monitoring mechanism 400, which includes a power sensor 401 disposed outside the spindle motor 2031 and a laser tool setter 402 disposed on the top surface inside the machining housing 201. The laser tool setter 402 is disposed corresponding to the tool holder 204.

[0033] In this technical solution, the power sensor 401 can monitor the power changes of the spindle motor 2031 in real time. When the tool 206 is worn or other abnormal, the power of the spindle motor 2031 will change, and the power sensor 401 can detect these abnormalities in time. The laser tool setter is a non-contact, optical measurement device. It emits a laser beam and detects the signal changes generated when the tool (blade or tool holder) blocks or reflects the laser beam, thereby accurately calculating the diameter and length of the tool, and even detecting the damage and shape of the tool. By transmitting the above tool monitoring signal to the control mechanism 500, it is convenient for the staff to understand the wear degree of the tool 206 in time, and then input the tool compensation amount in the CNC system or directly replace the tool with a new one to ensure machining accuracy.

[0034] For example, see Figure 3 and Figure 4As shown, it also includes a control mechanism 500, which includes a control cabinet 501 disposed on one side of the base 100. A touch screen 502 and control buttons 503 are provided on one outer surface of the control cabinet 501.

[0035] In this technical solution, operators can intuitively view the operating status and parameter settings of the equipment through the touch screen 502, and can also centrally control the equipment through the control button 503. The operation is simple and convenient. Through the control mechanism 500, operators can flexibly adjust various parameters of the equipment according to different processing needs, such as the spindle speed 203, the rotation speed of the tool holder 204, and the flow rate of the coolant, thereby achieving precise control of the elevator guide rail processing process.

[0036] Working Principle: When using this elevator guide rail machining center, the elevator guide rail to be processed is first placed on the raised electric lifting rod 102. Then, the electric lifting rod 102 retracts and moves the elevator guide rail to the bottom of the strip groove 101. The positioning fixture 103 then precisely positions and clamps the elevator guide rail, ensuring that it does not shift during processing. Simultaneously, the operator uses the touch screen 502 and control buttons 503 on the control cabinet 501 to set various parameters according to the processing requirements of the guide rail, such as the spindle speed, tool change sequence, processing depth, and length. Then, the servo motor 106 is started, driving the slider 105 to slide on the linear guide rail, causing the machining box 201 to move to both ends of the guide rail until both ends of the elevator guide rail enter the machining box 201 through the feed port 207. At this time, the laser range sensor 208 starts working, accurately measuring the distance between the elevator guide rail and the spindle 203, and feeding the data back to the control mechanism 500. The control mechanism 500 fine-tunes the position of the spindle robot 205 based on the feedback information to ensure that the spindle 203 is accurately aligned with the machining part of the elevator guide rail. At the same time, the reducer 209 drives the tool chassis 210. The appropriate tool 206 is rotated to the position connected to the spindle 203. After the spindle 203 is connected to the tool 206, the spindle motor 2031 drives the spindle 203 to rotate, and the tool 206 begins to process the elevator guide rail. During the processing, the water pump 302 draws coolant from the coolant tank 301 and sprays it onto the tool 206 and the processing area through the spray pipe 305 to reduce the temperature and flush the chips to the chip hopper 303. The exhaust fan 306 draws air containing fine powdery chips into the air filter 304, where the activated carbon filter adsorbs and filters them. (Power sensor...) The 401 unit monitors the power changes of the spindle motor 2031 in real time, while the laser tool setter 402 precisely measures the tool 206 and transmits the tool monitoring signal to the control mechanism 500 so that operators can promptly handle tool malfunctions. Once the machining of both ends of the elevator guide rail is complete, the servo motor 106 drives the slider 105 to slide along the linear guide rail 104, causing the machining box 201 to return to its original position. The positioning fixture 103 then releases its clamping of the elevator guide rail, and the electric lifting rod 102 lifts the machined elevator guide rail upwards for easy handling by the RGV trolley or forklift, completing the unloading operation. The entire machining process is efficient and precise, with all mechanisms working in concert, fully leveraging the advantages of this elevator guide rail machining center and providing a reliable guarantee for elevator guide rail production.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
