Description

Technical Field

[0001] This invention relates to the field of guide rail processing technology, specifically a cutting device for guide rail processing. Background Technology

[0002] A guide rail is a groove or ridge made of metal or other materials that supports, fixes, and guides moving devices or equipment and reduces their friction. Longitudinal grooves or ridges on a surface are used to guide and fix machine parts, special equipment, instruments, etc.

[0003] During the guide rail processing, it is usually necessary to cut the guide rail (a long strip of metal profile) into parts of a specified length according to the design size requirements. In the existing technology, when cutting the guide rail, the guide rail is usually first fixed by a fixing mechanism, and then the guide rail is cut by a downward-moving cutting machine.

[0004] However, existing technology cannot achieve the integration of guide rail fixing and cutting. In addition, during the process of the cutting machine moving upward and resetting after cutting the guide rail, the cutting machine will come into contact with the cut end face of the guide rail again. This contact can easily aggravate the unevenness of the cut end face of the guide rail, affecting the cutting effect. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting device for guide rail processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A cutting device for guide rail processing includes a processing table, support rods installed at the four corners of the processing table, and a top plate installed at the top of the support rods. Two symmetrically distributed first limiting grooves are formed on both sides of the processing table. A sliding table is slidably connected to each of the first limiting grooves. Control frames are installed on both sides of the sliding table, and the top of each control frame is slidably connected to a second limiting groove formed at the bottom of the top plate. The device also includes:

[0008] A movable frame is connected to the processing table via a lifting mechanism, which is used to drive the movable frame to move up and down.

[0009] A fixing mechanism is provided on both sides of the sliding table for fixing the guide rail;

[0010] A drive mechanism is disposed between the movable frame and the fixed mechanism, and is used to drive the fixed mechanism;

[0011] A control mechanism, which is mounted on a control frame, is used to limit the sliding table, drive the two sliding tables to move and reset, and release the fixing mechanism from the guide rail.

[0012] A moving mechanism is provided at the bottom of the movable frame, and a cutting mechanism is installed on the moving mechanism. The moving mechanism is used to adjust the cutting position of the cutting mechanism on the guide rail, and the cutting mechanism is used to cut the guide rail.

[0013] As a preferred embodiment of the present invention, the control mechanism includes a control block, a lower moving slot, an upper moving slot, a separation slot, and a reset slot. The lower moving slot, upper moving slot, separation slot, and reset slot are formed on the control frame and distributed in a parallelogram shape. The upper moving slot and lower moving slot are vertically arranged, while the separation slot and reset slot are obliquely arranged. The control block is located at both ends of the movable frame and can slide with the lower moving slot, upper moving slot, separation slot, and reset slot.

[0014] As a preferred embodiment of the present invention, the fixing mechanism includes side plates installed on both sides of the sliding table, two symmetrically distributed slide rods slidably arranged on the side plates, a fixing plate is installed at one end of the slide rod facing the middle of the sliding table, and a baffle is installed at the other end. An elastic element is provided between the fixing plate and the side plate, and a limit ring is provided on the slide rod.

[0015] As a preferred embodiment of the present invention, the driving mechanism includes a driving slider mounted on a fixed plate and slidably connected to a side plate. An inclined block is provided at the end of the driving slider away from the fixed plate. Driving plates are installed at the bottom of both sides of the movable frame, and a support sleeve slidably connected to the driving plate is installed on the processing table.

[0016] As a preferred embodiment of the present invention, the lifting mechanism includes lifting plates installed on both sides of the movable frame, and active telescopic components connected to the processing table are installed at both ends of the lifting plates.

[0017] As a preferred embodiment of the present invention, the moving mechanism includes mounting plates installed on both sides of the bottom of the movable frame, a plurality of guide rods are provided between the two mounting plates, a movable frame is slidably mounted on the guide rods, and a screw threadedly connected to the movable frame is rotatably provided between the two mounting plates, and a first driving member connected to the screw is mounted on one of the mounting plates.

[0018] As a preferred embodiment of the present invention, the cutting mechanism includes a cutting frame installed at the bottom of the movable frame, a drive shaft rotatably disposed inside the cutting frame, a cutting wheel mounted on the drive shaft, a second driving component connected to the drive shaft mounted on the cutting frame, and a cutting groove provided on the processing table.

[0019] The present invention has the following advantages:

[0020] In the process of cutting the guide rail by the descending cutting mechanism, this invention, in conjunction with the drive mechanism and control mechanism, can achieve integrated fixing and cutting of the guide rail. After the guide rail is cut, it can automatically separate the guide rail from the cutting mechanism on the two sliding platforms. This prevents the cutting mechanism from contacting the cut end face of the guide rail again during the upward reset process, thus avoiding aggravating the unevenness of the cut end face and improving the cutting effect. Furthermore, after the guide rail on the sliding platform is separated from the cutting mechanism, the fixing mechanism will reset and release the fixation of the guide rail, making it easy to remove the cut guide rail. The entire device can be reset by the upward reset of the cutting mechanism, resulting in better performance. Attached Figure Description

[0029] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0030] Please see Figure 1-7 A cutting device for guide rail processing includes a processing table 101, with support rods 102 installed at the four corners of the processing table 101, and a top plate 103 installed at the top of the support rods 102. Two symmetrically distributed first limiting grooves 104 are provided on both sides of the processing table 101. A sliding table 105 is slidably connected to each of the first limiting grooves 104. Control frames 107 are installed on both sides of the sliding table 105, and the top of the control frame 107 is slidably connected to a second limiting groove 106 located at the bottom of the top plate 103. The device also includes:

[0031] The movable frame 108 is connected to the processing table 101 via a lifting mechanism 5, which is used to drive the movable frame 108 to move up and down.

[0032] Fixing mechanism 2 is provided on both sides of the sliding table 105 and is used to fix the guide rail;

[0033] A drive mechanism 3 is disposed between the movable frame 108 and the fixed mechanism 2, and is used to drive the fixed mechanism 2.

[0034] Control mechanism 4, mounted on control frame 107, is used to limit the movement of sliding tables 105, drive the two sliding tables 105 to move and reset, and release the fixing mechanism 2 from the guide rail. Control mechanism 4 includes control block 401, lower moving groove 402, upper moving groove 404, separation groove 403, and reset groove 405. The lower moving groove 402, upper moving groove 404, separation groove 403, and reset groove 405 are formed on control frame 107 and are flush with it. The components are arranged in a quadrilateral pattern. The upper moving groove 404 and the lower moving groove 402 are vertically arranged, while the separation groove 403 and the reset groove 405 are obliquely arranged. The separation groove 403 is located at the bottom of the upper moving groove 404 and the lower moving groove 402, and the reset groove 405 is located at the top of the upper moving groove 404 and the lower moving groove 402. The control block 401 is located at both ends of the movable frame 108 and can slide with the lower moving groove 402, the upper moving groove 404, the separation groove 403 and the reset groove 405.

[0035] The moving mechanism 6 is located at the bottom of the movable frame 108, and a cutting mechanism 7 is installed on the moving mechanism 6. The moving mechanism 6 is used to adjust the cutting position of the cutting mechanism 7 on the guide rail, and the cutting mechanism 7 is used to cut the guide rail.

[0036] This invention places the guide rail on two sliding tables 105, and then drives the movable frame 108 to descend via the lifting mechanism 5. During the descent of the movable frame 108, the control blocks 401 at both ends of the movable frame 108 move along the lower sliding groove 402. During this process, the driving mechanism 3 drives the fixing mechanism 2 to fix the two ends of the guide rail on the sliding table 105 in a centered position, thereby improving the stability of the cutting mechanism 7 in cutting the guide rail and ensuring the effect of cutting the guide rail. When the cutting mechanism 7 completes the cutting of the guide rail, the control block 401 is at the bottom of the lower sliding groove 402. As the movable frame 108 descends, the control block 401 moves along the lower sliding groove 402. As 08 continues to descend, control block 401 slides along separation groove 403. During this process, since separation groove 403 is angled, control block 401 pushes control frame 107 to move along second limiting groove 106 and pushes sliding table 105 to move along first limiting groove 104 towards the end of processing table 101. This separates the guide rails on the two cut processing tables 101 from the cutting mechanism 7, thus preventing the cutting mechanism 7 from contacting the cut surface of the guide rail again during its upward reset process, which would exacerbate the unevenness of the cut end surface and affect the cutting effect. Furthermore, during the movement of the sliding table 105 towards the end of the processing table 101, the drive mechanism 3 will release the drive of the fixing mechanism 2, causing the fixing mechanism 2 to reset and no longer fix the guide rail, thus facilitating the removal of the cut guide rail. When the two sliding tables 105 have separated and the fixing mechanism 2 has released the fixation of the guide rail, the control block 401 will slide to the bottom of the upper moving groove 404. Then, under the drive of the lifting mechanism 5, the movable frame 108 will move upward and reset, thereby driving the cutting mechanism 7 to move upward and reset. During the upward and reset process, the control block 401 will move along the upper moving groove 404. 4. As the upper moving groove 404 restricts the position of the control frame 107 and the sliding table 105, when the control block 401 moves to the top of the upper moving groove 404, it will continue to move along the reset groove 405. During this process, since the reset groove 405 is set at an angle, the control block 401 will push the control frame 107 to move, causing the sliding table 105 to move along the first limiting groove 104 towards the middle of the processing table 101. When the control block 401 moves along the reset groove 405 to the top of the lower moving groove 402, the sliding table 105 is reset, and the entire cutting device is reset.

[0037] In one instance of this embodiment, please refer to Figure 2 and Figure 4 The fixing mechanism 2 includes side plates 201 installed on both sides of the sliding table 105. Two symmetrically distributed slide rods 202 are slidably arranged on the side plates 201. A fixing plate 203 is installed at one end of the slide rod 202 facing the middle of the sliding table 105, and a baffle 204 is installed at the other end. An elastic element 205 is provided between the fixing plate 203 and the side plates 201, and a limit ring 206 is provided on the slide rod 202.

[0038] Due to the elastic tension of the elastic element 205 and the cooperation of the limiting ring 206, the initial position of the fixed plate 203 on the processing table 101 is fixed. During the downward movement of the cutting mechanism 7, the driving mechanism 3 will push the fixed plate 203 to move, so that the fixed plate 203 fixes the two sides of the guide rail.

[0039] Furthermore, a rubber layer can be laid on the surface of the fixing plate 203 to prevent the fixing plate 203 from directly contacting the guide rail and causing damage to the surface of the guide rail.

[0040] Furthermore, the specific structure of the elastic element 205 is not limited; preferably, the elastic element 205 is configured as a spring.

[0041] In one instance of this embodiment, please refer to Figure 4 and Figure 5 The driving mechanism 3 includes a driving slider 301 mounted on the fixed plate 203 and slidably connected to the side plate 201. An inclined block 302 is provided at one end of the driving slider 301 away from the fixed plate 203. The bottom of both sides of the movable frame 108 is equipped with a driving plate 303. The bottom end of the driving plate 303 is provided with an inclined surface that is the same as that of the inclined block 302. A support sleeve 304 slidably connected to the driving plate 303 is mounted on the processing table 101. The support sleeve 304 is used to limit the driving plate 303 and provide support for its side walls.

[0042] In the initial state, i.e., the entire device is in a reset state, the control block 401 is located at the top of the lower sliding groove 402. At this time, the drive plate 303 is aligned with the inclined block 302 at the end of the drive slider 301. Thus, during the descent of the movable frame 108 driven by the lifting mechanism 5, the control block 401 will move along the lower sliding groove 402. When the drive plate 303 contacts the inclined block 302, it will push the inclined block 302 along the inclined surface of the inclined block 302, thereby pushing the drive slider 301 to move, so that the fixed... The plate 203 is pushed by the driven slider 301. When the driven plate 303 separates from the inclined surface of the inclined block 302, the two fixed plates 203 just abut against the two side walls of the guide rail, thereby fixing the two ends of the guide rail in the center, thus improving the stability of the cutting mechanism 7 in cutting the guide rail and ensuring the effect of cutting the guide rail. In the subsequent movement, the driven plate 303 will maintain the contact limit with the inclined block 302, thereby maintaining the fixation of the guide rail. During this process, the cutting mechanism 7 will cut the guide rail.

[0043] When the guide rail is cut off, the control block 401 is located at the bottom of the lower groove 402. As the movable frame 108 continues to move down, the control block 401 slides along the separation groove 403. Since the separation groove 403 is set at an angle, the control block 401 pushes the control frame 107 to move and pushes the sliding table 105 to move towards the end of the processing table 101, so that the guide rails on the two cut processing tables 101 are separated from the cutting mechanism 7. During the process of the sliding table 105 moving towards the end of the processing table 101, the contact area between the drive plate 303 and the inclined block 302 gradually decreases until the drive plate 303 and the inclined block 302 are separated. At this time, under the elastic tension of the elastic element 205, the fixed plate 203 will move to one side of the side plate 201 until the limiting ring 206 on the slide rod 202 abuts against the side plate 201, thereby completing the reset of the fixed plate 203 and releasing the fixation of the guide rail, so as to facilitate the removal of the cut guide rail.

[0044] In one instance of this embodiment, please refer to Figure 1 and Figure 5 The lifting mechanism 5 includes lifting plates 501 installed on both sides of the movable frame 108, and active telescopic components 502 connected to the processing table 101 are installed at both ends of the lifting plates 501.

[0045] The active telescopic component 502 can drive the movable frame 108 to rise and fall, thereby driving the cutting mechanism 7 to descend and cut off the guide rail.

[0046] Furthermore, the specific structure of the active telescopic component 502 is not limited; preferably, the active telescopic component 502 is configured as a hydraulic rod.

[0047] In one instance of this embodiment, please refer to Figure 5 and Figure 7 The moving mechanism 6 includes mounting plates 601 installed on both sides of the bottom of the movable frame 108. A plurality of guide rods 602 are provided between the two mounting plates 601. A movable frame 603 is slidably mounted on the guide rods 602. A screw 604 threadedly connected to the movable frame 603 is rotatably provided between the two mounting plates 601. A first driving member 605 connected to the screw 604 is installed on one of the mounting plates 601.

[0048] During the guide rail cutting process, the position of the cutting mechanism 7 between the two sliding tables 105 can be adjusted as needed to facilitate the adjustment of the cutting position of the guide rail. The first driving member 605 drives the screw 604 to rotate, thereby driving the moving frame 603 to move along the guide rod 602 and changing the position of the cutting mechanism 7.

[0049] Furthermore, the specific structure of the first driving component 605 is not limited; preferably, the first driving component 605 is configured as a motor.

[0050] In one instance of this embodiment, please refer to Figure 7 The cutting mechanism 7 includes a cutting frame 701 installed at the bottom of the movable frame 603. A drive shaft 702 is rotatably arranged inside the cutting frame 701. A cutting wheel 703 is installed on the drive shaft 702. A second driving component 704 connected to the drive shaft 702 is installed on the cutting frame 701. A cutting groove 705 is opened on the processing table 101.

[0051] During the process of cutting the guide rail, the second driving component 704 drives the driving shaft 702 to rotate, and the driving shaft 702 drives the cutting wheel 703 to rotate. During the descent of the movable frame 108, the cutting wheel 703 can cut the guide rail.

[0052] Furthermore, the specific structure of the second driving element 704 is not limited; preferably, the second driving element 704 is configured as a motor.

[0053] In the process of cutting the guide rail by the descending cutting mechanism 7, the present invention, in conjunction with the driving mechanism 3 and the control mechanism 4, can achieve the integration of fixing and cutting the guide rail. After the guide rail is cut, the guide rail on the two sliding tables 105 can be automatically separated from the cutting mechanism 7. This prevents the cutting mechanism 7 from contacting the cut end face of the guide rail again during the upward reset process, thus avoiding aggravating the unevenness of the cut end face of the guide rail and improving the cutting effect. After the guide rail on the sliding table 105 is separated from the cutting mechanism 7, the fixing mechanism 2 will also reset and release the fixation of the guide rail, making it easier to remove the cut guide rail. The entire device can be reset by the upward reset of the cutting mechanism 7, resulting in better performance.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
