Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail production technology, specifically to a surface texture treatment device for elevator guide rails after planing. Background Technology

[0002] Elevator guide rails are elevator components made of steel rails and connecting plates, and are divided into car guide rails and counterweight guide rails. They are classified into three types based on their cross-sectional shape: T-shaped, L-shaped, and hollow.

[0003] Existing surface texture treatment devices for elevator guide rails after planing mostly use shot peening to treat the guide rail surface. However, most of them use CNC devices to perform shot peening on multiple guide rails simultaneously. However, when the CNC frame is not fully loaded with guide rails, the shot peening nozzle cannot close in time, resulting in waste of shot peening material. At the same time, it can only fix guide rails of a fixed model. However, different guide rail models have different edge thicknesses, making it impossible to fix multiple types of guide rails. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a surface texture treatment device for elevator guide rails after planing, which has the advantages of individually closing the nozzle and fixing multiple guide rails, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a surface texture treatment device for elevator guide rails after planing, comprising a CNC base, a support frame fixedly installed on the top of the CNC base, a storage box and a pump body fixedly installed on the top of the support frame, a connecting pipe fixedly installed on the output shaft of the pump body, a pressure pipe fixedly installed on the inner wall of the support frame, a fixing block fixedly installed at the bottom of the pressure pipe, a movable CNC frame slidably connected to the inner wall of the CNC base, a sealing ball and a worm gear rotatably connected to the inner wall of the fixing block, a worm wheel fixedly installed on the outer wall of the sealing ball, a motor fixedly installed on the outer wall of the movable CNC frame, a double-ended lead screw fixedly installed on the output shaft of the motor, a sliding block and a lifting plate slidably connected to the inner wall of the movable CNC frame, a limit plate fixedly installed on the inner wall of the movable CNC frame, a limit post fixedly installed on the inner wall of the lifting plate, a spring provided on the inner wall of the lifting plate, an extension strip fixedly installed on the inner wall of the movable CNC frame, and a spray pipe fixedly installed at the bottom of the fixing block.

[0006] As a preferred technical solution of this utility model: the worm is located at the top of the worm wheel, and the worm wheel and the worm are meshed.

[0007] As a preferred technical solution of this utility model: there are two sliding blocks, and the two double-ended lead screws are symmetrically arranged on both sides of the inner wall of the moving CNC frame. The double-ended lead screws pass through the two sliding blocks, and the double-ended lead screws are threadedly connected to the two sliding blocks.

[0008] As a preferred technical solution of this utility model: the top of the sliding block and the bottom of the lifting plate are both set with slopes, and the top of the sliding block and the bottom of the lifting plate are parallel.

[0009] As a preferred technical solution of this utility model: the limiting plate is located on the inner wall of the lifting plate, and the size of the limiting plate is adapted to the inner wall of the lifting plate.

[0010] As a preferred technical solution of this utility model: the limiting post penetrates the limiting plate, and the limiting post and the limiting plate are slidably connected.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The surface texture treatment device for the elevator guide rail after planing rotates the worm gear, which in turn drives the worm wheel to rotate through meshing with it. This causes the worm wheel to drive the sealing ball to rotate, and the opening of the sealing ball rotates towards the inner wall of the fixed block. This prevents the opening of the sealing ball from being parallel to the nozzle, thereby blocking the spraying of material from a single nozzle and preventing material loss.

[0012] 2. The surface texture treatment device for the elevator guide rail after planing, by starting the motor, causes the double-headed screw to rotate, which in turn causes the double-headed screw to move two sliding blocks towards the bottom of the lifting plate. Through the contact between the sliding blocks and the bottom of the lifting plate, the sliding blocks press the lifting plate upward, which in turn causes the lifting plate to move upward, causing the lifting plate to move the guide rail upward, so that the top of the guide rail is in contact with the bottom of the extension strip. At this time, the guide rail is pressed by the lifting plate and the extension strip. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1 - Figure 5 A surface texture treatment device for elevator guide rails after planing includes a CNC base 1, a support frame 2 fixedly mounted on the top of the CNC base 1, a storage box 3 and a pump body 4 fixedly mounted on the top of the support frame 2, a connecting pipe 5 fixedly mounted on the output shaft of the pump body 4, a pressure pipe 6 fixedly mounted on the inner wall of the support frame 2, a fixing block 7 fixedly mounted on the bottom of the pressure pipe 6, a movable CNC frame 12 slidably connected to the inner wall of the CNC base 1, and a sealing ball 8 and a worm gear 10 rotatably connected to the inner wall of the fixing block 7. A worm gear 9 is fixedly installed on the wall. A motor 13 is fixedly installed on the outer wall of the movable CNC frame 12. A double-headed lead screw 14 is fixedly installed on the output shaft of the motor 13. A sliding block 15 and a lifting plate 16 are slidably connected to the inner wall of the movable CNC frame 12. A limit plate 17 is fixedly installed on the inner wall of the movable CNC frame 12. A limit post 18 is fixedly installed on the inner wall of the lifting plate 16. A spring 19 is provided on the inner wall of the lifting plate 16. An extension strip 20 is fixedly installed on the inner wall of the movable CNC frame 12. A nozzle 11 is fixedly installed at the bottom of the fixed block 7.

[0017] In the above structure, there are several fixing blocks 7, sealing balls 8, worm gears 9, worms 10 and nozzles 11, and the number of fixing blocks 7, sealing balls 8, worm gears 9, worms 10 and nozzles 11 corresponds to the number of guide rails. The guide rails are surface treated by shot peening with several fixing blocks 7, sealing balls 8, worm gears 9, worms 10 and nozzles 11.

[0018] In a preferred embodiment, the worm 10 is located on top of the worm wheel 9, and the worm wheel 9 and the worm 10 are engaged.

[0019] In the above structure, by rotating the worm 10, the worm 10 drives the worm wheel 9 to rotate through meshing with the worm wheel 9, which in turn drives the sealing ball 8 to rotate, thereby adjusting the opening direction of the sealing ball 8.

[0020] In a preferred embodiment, there are two sliding blocks 15, and two double-ended lead screws 14 are symmetrically arranged on both sides of the inner wall of the movable CNC frame 12. The double-ended lead screws 14 pass through the two sliding blocks 15, and the double-ended lead screws 14 and the two sliding blocks 15 are threadedly connected.

[0021] In the above structure, by starting the motor 13, the motor 13 drives the double-ended lead screw 14 to rotate, which in turn causes the double-ended lead screw 14 to drive the two sliding blocks 15 to move through the threaded connection of the two sliding blocks 15, so that the two sliding blocks 15 move simultaneously to the center or to both sides.

[0022] In a preferred embodiment, the top of the sliding block 15 and the bottom of the lifting plate 16 are both inclined, and the top of the sliding block 15 and the bottom of the lifting plate 16 are parallel.

[0023] In the above structure, by moving the top inclined surface of the sliding block 15 towards the bottom inclined surface of the lifting plate 16, the top inclined surface of the sliding block 15 and the bottom inclined surface of the lifting plate 16 come into contact. At this time, if the sliding block 15 continues to move, the top inclined surface of the sliding block 15 will press the bottom inclined surface of the lifting plate 16, thereby causing the lifting plate 16 to move upward. This causes the lifting plate 16 to drive the top guide rail to move upward, thereby fixing the upper and lower edges of the guide rail with the lifting plate 16 and the extension bar 20.

[0024] In a preferred embodiment, the limiting plate 17 is located on the inner wall of the lifting plate 16, and the size of the limiting plate 17 is adapted to the inner wall of the lifting plate 16.

[0025] In the above structure, the lifting plate 16 is limited by the limiting plate 17, so that when the lifting plate 16 moves, its inner wall cannot be separated from the limiting plate 17, and thus the lifting plate 16 cannot be separated from the interior of the moving CNC frame 12 when it moves.

[0026] In a preferred embodiment, the limiting post 18 passes through the limiting plate 17, and the limiting post 18 and the limiting plate 17 are slidably connected.

[0027] In the above structure, the limiting plate 17 is penetrated by the limiting post 18, so that the limiting post 18 can only move within the inner wall of the limiting plate 17 when it moves, so that the limiting post 18 is limited by the limiting plate 17, and thus the lifting plate 16 is limited by the limiting post 18, so that the lifting plate 16 will not tilt when it moves.

[0028] Working Principle: When using the equipment, the guide rail is placed on the inner wall of the lifting plate 16. The motor 13 is then started, causing the double-ended lead screw 14 to rotate. This, in turn, causes the lead screw 14 to move the two sliding blocks 15 to the sides via their threaded connection. The top inclined surface of the sliding block 15 moves towards the bottom inclined surface of the lifting plate 16, bringing them into contact. Continuing to move the sliding block 15 further compresses the bottom inclined surface of the lifting plate 16, causing the lifting plate 16 to move upwards. This, in turn, moves the top guide rail upwards, thus lifting the plate. Plate 16 and extension strip 20 fix the upper and lower edges of the guide rail. At this time, the CNC base 1 is activated, causing the CNC base 1 to control the moving CNC frame 12 to move to the bottom of the support frame 2. At this time, the guide rail surface is shot-blasted through the storage box 3, pump body 4, connecting pipe 5, pressurizing pipe 6 and fixing block 7. When it is necessary to close a fixing block 7, the worm 10 is rotated, which in turn causes the worm 10 to mesh with the worm wheel 9 and drive the worm wheel 9 to rotate. The worm wheel 9 drives the sealing ball 8 to rotate, which causes the opening of the sealing ball 8 to rotate toward the inner wall of the fixing block 7. This causes the opening of the sealing ball 8 to no longer be parallel to the nozzle 11, thereby blocking the spraying of material from a single nozzle 11 and preventing material loss.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
