Description

Technical Field

[0001] This utility model relates to a machine tool guide rail limiting device, belonging to the technical field of machine tool limiting equipment. Background Technology

[0002] The main function of the guide rail limit device is to limit the range of motion of the machine tool during operation, prevent the machine tool from exceeding the preset working range due to loss of control or other unexpected situations, thereby protecting the safety of the machine tool and the operator.

[0003] Some existing machine tool guide rail limiting devices, after being installed on the slide rail, require the user to use a tool to loosen them from the surface of the slide rail before adjusting their position. This process is time-consuming and laborious, making them inconvenient to use. To address these issues, we provide a machine tool guide rail limiting device. Utility Model Content

[0004] To solve the above problems, this utility model provides a machine tool guide rail limiting device, and the specific technical solution is as follows:

[0005] A machine tool guide rail limiting device includes a guide rail body, the guide rail body having a sliding groove inside, teeth connected to the inner sidewall of the sliding groove, a toothed plate meshing with the outer surface of the teeth, a limiting block slidably connected to the outer surface of the toothed plate, an adjusting plate connected to the outer surface of the toothed plate, a limiting plate connected inside the limiting block, a movable rod slidably connected inside the limiting plate, one end of the movable rod contacting a push rod, the end of the push rod away from the movable rod contacting an insert rod, and a spring connected to the end of the insert rod away from the movable rod.

[0006] Preferably, a pad is slidably connected to the outer surface of the guide rail body, a damper is installed inside the limiting block, the output end of the damper is connected to the outer surface of the pad, and a spring is sleeved on the outer surface of the damper.

[0007] Preferably, a baffle is slidably connected inside the limiting plate, and the outer surface of the baffle is slidably connected to one end of the movable rod.

[0008] Preferably, the outer surface of the movable rod is connected to a blocking block, and the outer surface of the blocking block is slidably connected to the inside of the limiting plate.

[0009] Preferably, the outer surface of the limiting block is slidably connected to the outer surface of the guide rail body, the outer surface of the toothed plate is slidably connected to the outer surface of the limiting plate, and the outer surface of the adjusting plate is slidably connected to the interior of the limiting plate.

[0010] Preferably, one end of the spring is connected to the interior of the limiting block, and the outer surface of the insert rod is slidably connected to the interior of the limiting block.

[0011] Preferably, the outer surface of the push rod is slidably connected to the inside of the toothed plate, and the outer surface of the insert rod is slidably connected to the inside of the toothed plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This machine tool guide rail limiting device uses the cooperation between components such as the toothed plate and the movable rod. First, the toothed plate can mesh with the teeth. After the toothed plate meshes with the teeth, the limiting block cannot move, thus fixing the position of the limiting block. This allows the user to arbitrarily restrict the limiting block to a certain position above the guide rail body. The movable rod can move. When it is necessary to separate the toothed plate from the teeth, the user only needs to press the movable rod to move the position of the toothed plate and separate it from the teeth. No tools are needed, which is very convenient and solves the problem that adjusting the limiting device requires the use of tools.

[0014] 2. This machine tool guide rail limiting device uses the cooperation between components such as baffles and blocking blocks. The baffle can block one end of the movable rod. After the baffle is installed on the limiting plate body, the user cannot press down the movable rod, thus preventing accidental contact with the movable rod. The blocking block restricts the movable rod's movement. When the movable rod moves, it will move the blocking block along with it. The movement of the blocking block is restricted by the limiting plate, thus preventing the movable rod from detaching from the limiting plate. It is very useful. Attached Figure Description

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1 - Figure 5 The guide rail body 1 includes a slide groove 2 inside the guide rail body 1. The inner side wall of the slide groove 2 is connected with teeth 3. The inner side wall of the slide groove 2 is relatively smooth, so the friction force on other items when they move on the inner side wall of the slide groove 2 is small. The inner side wall of the slide groove 2 will fix the position of the teeth 3.

[0023] The outer surface of the tooth 3 is engaged with the tooth plate 4. The outer surface of the tooth plate 4 is slidably connected to the limiting block 5. When the tooth 3 and the tooth plate 4 are engaged, the tooth plate 4 cannot move along the direction of the guide rail body 1. The tooth plate 4 is inside the limiting block 5. When the limiting block 5 moves along the guide rail body 1, it needs to move the tooth plate 4 with it. Thus, when the tooth plate 4 and the tooth 3 are engaged, the limiting block 5 cannot move along the guide rail body 1.

[0024] An adjusting plate 6 is connected to the outer surface of the toothed plate 4, and a limiting plate 7 is connected inside the limiting block 5. The toothed plate 4 will fix the position of the adjusting plate 6. When the adjusting plate 6 moves, it will move the toothed plate 4 with it. In this way, the user can move the toothed plate 4 by moving the adjusting plate 6. The limiting block 5 will fix the position of the limiting plate 7, so that the limiting plate 7 cannot move.

[0025] The limiting plate 7 has a sliding connection to a movable rod 8. One end of the movable rod 8 contacts a push rod 9. The limiting plate 7 restricts the direction in which the movable rod 8 can move, so that the position of the movable rod 8 will not deviate. The movable rod 8 will abut against the push rod 9. When the movable rod 8 moves within the guide rail body 1, it can push the push rod 9 to move. A part of the push rod 9 is located within the limiting plate 7.

[0026] The end of the push rod 9 away from the movable rod 8 is in contact with the insertion rod 10. The end of the insertion rod 10 away from the movable rod 8 is connected to a spring 11. When the movable rod 8 pushes the push rod 9 to move, the push rod 9 will push the insertion rod 10 to move. The spring 11 can provide a pushing force to the insertion rod 10. After the push rod 9 loses the push from the movable rod 8, the spring 11 will push the insertion rod 10, so that the insertion rod 10 will push the push rod 9 back to its original position.

[0027] A pad 12 is slidably connected to the outer surface of the guide rail body 1. A damper 13 is installed inside the limiting block 5. The guide rail body 1 restricts the direction in which the pad 12 can move, thereby preventing the pad 12 from deviating from its position. A buffer pad is installed on the surface of the pad 12. The limiting block 5 restricts the position of the damper 13. Multiple dampers 13 are provided inside the limiting block 5.

[0028] The output end of the damper 13 is connected to the outer surface of the pad 12. The outer surface of the damper 13 is fitted with a spring 14. When an object pushes the pad 12 at high speed, the damper 13 will provide a buffer for the pad 12, so that the high-speed moving object is not easily damaged. The damper 13 is reset by the spring 14.

[0029] The limiting plate 7 has a baffle 15 inside. The outer surface of the baffle 15 is slidably connected to one end of the movable rod 8. When the baffle 15 is installed in the limiting plate 7, the limiting plate 7 will lock the baffle 15. The surface of the baffle 15 will be provided with a handle for the user to pull it out from the limiting plate 7. The baffle 15 will block the movable rod 8, so that the user cannot press the movable rod 8 normally.

[0030] A blocking block 16 is connected to the outer surface of the movable rod 8. The outer surface of the blocking block 16 is slidably connected to the inside of the limiting plate 7. The movable rod 8 will fix the position of the blocking block 16. When the movable rod 8 moves, it will move the blocking block 16 with it. A spring is installed on the surface of the blocking block 16 near the guide rail body 1. When the blocking block 16 moves to the guide rail body 1, the spring will provide it with a force in the opposite direction, so that the movable rod 8 can be reset after being pressed down.

[0031] The outer surface of the limiting block 5 is slidably connected to the outer surface of the guide rail body 1, the outer surface of the toothed plate 4 is slidably connected to the outer surface of the limiting plate 7, and the outer surface of the adjusting plate 6 is slidably connected to the inside of the limiting plate 7. The guide rail body 1 restricts the direction in which the limiting block 5 can move, thereby preventing the limiting plate 7 from deviating from its position. The limiting plate 7 restricts the direction in which the toothed plate 4 can move, thereby preventing the toothed plate 4 from deviating from its position. The limiting plate 7 restricts the position in which the adjusting plate 6 can move, ensuring that the adjusting plate 6 does not deviate from its position.

[0032] One end of the spring 11 is connected to the inside of the limiting block 5, and the outer surface of the insertion rod 10 is slidably connected to the inside of the limiting block 5. The limiting block 5 restricts the position of the spring 11 and the direction in which the insertion rod 10 can move, thereby preventing the insertion rod 10 from deviating from its position.

[0033] The outer surface of the push rod 9 is slidably connected to the inside of the toothed plate 4, and the outer surface of the insert rod 10 is slidably connected to the inside of the toothed plate 4. The toothed plate 4 restricts the direction in which the push rod 9 can move. The part of the insert rod 10 inside the toothed plate 4 has an inclined surface. When the toothed plate 4 moves, the insert rod 10 can be inserted into its interior through the inclined surface.

[0034] The damper 13 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources.

[0035] When using this utility model, firstly, the baffle 15 needs to be removed and the movable rod 8 needs to be pressed. The movement of the movable rod 8 will push the push rod 9 to move, and the movement of the push rod 9 will push the insertion rod 10 out. Then, the user can move the limiting block 5 and move the limiting block 5 to the appropriate position. Then, the user needs to move the adjusting plate 6. The movement of the adjusting plate 6 will move the toothed plate 4, thereby moving the toothed plate 4 to the position where it engages with the teeth 3. At this time, the insertion rod 10 will be inserted into the interior of the toothed plate 4 under the action of the spring 11.

[0036] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
