Description

Technical Field

[0001] This utility model relates to the field of guide rail clamping technology, specifically a high-precision guide rail clamping device. Background Technology

[0002] As is well known, a guide rail clamp is a brake used to clamp guide rails, position and fix working parts, and prevent them from falling or vibrating.

[0003] A search revealed that a utility model patent with Chinese patent authorization announcement number CN213685045U discloses a high-precision guide rail clamp. The limiting block set inside the guide rail receiving groove can be adjusted in position by rotating the screw, so that the guide rail receiving groove can be used for different guide rails. This solves the problem that the existing guide rail clamps have low precision and cannot adapt to a variety of guide rails.

[0004] Although the above technical solution solves the problems of low precision and inability to adapt to various guide rails in existing guide rail clamps, the above technical solution uses a clamping spring to drive the piston to move, and then the piston pushes the cylindrical pin to clamp the guide rail. The workpiece that needs to be fixed may be subjected to forces in various directions during the processing. Since the above solution clamps the guide rail with a clamping spring, when the force on the workpiece exceeds the force provided by the spring, the device may shift in position, thereby affecting the fixing effect on the workpiece, causing the device to shift in position, and thus affecting the work of the operator. Utility Model Content

[0006] To overcome the problem of poor fixing effect of existing products, which may cause the workpiece to shift position, this utility model provides a high-precision guide rail clamp with good fixing effect.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-precision guide rail clamp, comprising:

[0009] A limiting box, wherein a first sliding groove is provided on the limiting box, and a first through hole is provided at one end of the limiting box, the first through hole communicating with the first sliding groove;

[0010] The fixing assembly includes a bidirectional lead screw, two first sliders, a first connecting shaft, and a first rotating handle. The bidirectional lead screw is rotatably disposed in the first slide groove, and each of the first sliders is slidably disposed in the first slide groove. Each of the first sliders is respectively threaded onto both sides of the bidirectional lead screw. The first connecting shaft is fixedly disposed at one end of the bidirectional lead screw and is rotatably disposed in the first through hole. The first rotating handle is fixedly disposed at one end of the first connecting shaft.

[0011] Preferably, it also includes two opposing fixing blocks, each of which is fixedly disposed at the bottom of the limiting box, and each of the fixing blocks is provided with a second through hole, and a second slider is slidably disposed in each of the second through holes.

[0012] Furthermore, it also includes two third through holes, each of which is respectively opened on the corresponding second slider. Each second through hole is slidably provided with a limit rod, and the second slider is slidably disposed in the second through hole through the limit rod.

[0013] Furthermore, it also includes two first blind slots, each of which is respectively opened on the corresponding fixed block, and a third slider is slidably disposed in each first blind slot, and one end of each limiting rod is respectively fixedly disposed on the large surface of the corresponding third slider.

[0014] A further embodiment includes at least two second blind slots, each second blind slot being respectively opened on the corresponding fixed block, and a fourth slider being slidably disposed in each second blind slot, with the other end of each limiting rod being respectively fixedly disposed on the large surface of the corresponding fourth slider.

[0015] Furthermore, it also includes two fourth through holes, each of which is respectively opened on the corresponding fixed block. A screw is rotatably disposed in the first blind groove. The third slider is threadedly connected to the screw. A second connecting shaft is fixedly disposed at one end of the screw.

[0016] Based on the aforementioned scheme, two anti-wear pads are also included, each of which is fixedly disposed on the large surface of the corresponding first slider.

[0017] Furthermore, based on the aforementioned scheme, the first groove and the first slider are polygonal in shape to match each other.

[0018] (III) Beneficial Effects

[0019] This high-precision guide rail clamp includes a limit box and a fixing component. When the guide rail needs to be clamped, the operator rotates the first handle. The rotation of the first handle drives the first connecting shaft to rotate, which in turn drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the two first sliders to move towards each other, which in turn drives the two anti-wear blocks to move towards each other, thereby clamping the guide rail and limiting the position of the workpiece. When the workpiece is subjected to force, the clamping of the guide rail by the first sliders limited by the bidirectional lead screw and the anti-wear blocks can effectively prevent the workpiece from shifting position under force.

[0025] 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.

[0026] See Figures 1-2A high-precision guide rail clamp includes a limiting box 1, which serves as the main body for mounting and fixing components 4. The limiting box 1 can be made of manganese steel, which improves the strength of the device while providing support for the workpiece requiring position restriction, preventing workpiece misalignment. For mounting and fixing components 4, a first sliding groove 2 is provided on the limiting box 1. The first sliding groove 2 is square in shape and can restrict the movement direction of the first slider 6, preventing the first slider 6 from shifting position and thus affecting the effect of the high-precision guide rail clamp. A first through hole 3 is provided at one end of the limiting box 1, which communicates with the first sliding groove 2, providing a mounting base for subsequent parts.

[0027] The fixing component 4 is used to clamp the guide rail, thereby limiting the position of the workpiece. The fixing component 4 includes a bidirectional lead screw 5, two first sliders 6, a first connecting shaft 7, and a first rotating handle 8. The bidirectional lead screw 5 is rotatably disposed in the first slide groove 2. The rotation of the bidirectional lead screw 5 drives the first sliders 6 located on both sides of the bidirectional lead screw 5 to move towards each other, thereby clamping the guide rail. Both first sliders 6 are slidably disposed in the first slide groove 2. The two first sliders 6 are respectively threaded on both sides of the bidirectional lead screw 5. The first sliders 6 are square in shape to fit the first slide groove 2 to prevent the first sliders 6 from rotating when the bidirectional lead screw 5 rotates. The first connecting shaft 7 is welded to one end of the bidirectional lead screw 5 and is rotatably disposed in the first through hole 3. The first connecting shaft 7 can be rotatably disposed in the first through hole 3 through a bearing to prevent the first connecting shaft 7 from shifting position, thereby limiting the position of the bidirectional lead screw 5. The first rotating handle 8 is welded to one end of the first connecting shaft 7. Multiple grooves are distributed in a circumferential array on the outer periphery of the first rotating handle 8 to facilitate the rotation of the first rotating handle 8 by the operator, thereby driving the first connecting shaft 7 to rotate.

[0028] In this embodiment, the operator drives the first connecting shaft 7 to rotate via the first rotating handle 8. The rotation of the first connecting shaft 7 drives the bidirectional lead screw 5 to rotate. The rotation of the bidirectional lead screw 5 drives the two first sliders 6 connected by threads to move towards each other in the first slide groove 2, thereby achieving the purpose of clamping the guide rail.

[0029] First, refer to Figure 3 and 4 In this embodiment, two opposing fixing blocks 9 are also included. Both fixing blocks 9 are welded to the bottom of the limiting box 1. The two fixing blocks 9 are respectively welded to the two ends of the bottom of the limiting box 1, serving as the basis for subsequent parts installation. Each fixing block 9 has a second through hole 10. The shape of the second through hole 10 is square. In this embodiment, the shape of the second through hole 10 is square, which can restrict the movement direction of the second slider 11. The second slider 11 is slidably disposed in each of the two second through holes 10. The shape of the second slider 11 is square and adapted to the second through hole 10, which can prevent the second slider 11 from shifting its position in the second through hole 10.

[0030] Then, refer to Figure 3 and Figure 4 In this embodiment, two third through holes 12 are also included. The two third through holes 12 are respectively opened on the corresponding second sliders 11. Limiting rods 13 are slidably arranged in both second through holes 10. The second sliders 11 are slidably arranged in the second through holes 10 through the limiting rods 13.

[0031] In this embodiment, the device can use different types of guide rails by adjusting the position of the second slider 11 by the operator. The second sliders 11 on both sides can limit the high-precision guide rail clamp so that the device will not detach from the guide rail when the guide rail is not clamped, thus avoiding unnecessary trouble for the operator.

[0032] Secondly, see Figure 3 and Figure 4 In this embodiment, two first blind grooves 14 are also included. The two first blind grooves 14 are respectively opened on the corresponding fixed blocks 9. A third slider 15 is slidably arranged in the two first blind grooves 14. One end of the two limiting rods 13 is respectively welded to the large surface of the corresponding third slider 15.

[0033] In this embodiment, the movement of the third slider 15 drives the corresponding limiting rod 13 to move within the second through hole 10, thereby driving the second slider 11 to move within the second through hole 10, thus adjusting the length of the second slider 11 protruding from the second through hole 10 to adapt to different types of guide rails.

[0034] See again Figure 3 and Figure 4 In this embodiment, at least two second blind grooves 16 are also included. The two second blind grooves 16 are respectively opened on the corresponding fixed blocks 9. The second blind grooves 16 are polygonal. In this embodiment, the second blind grooves 16 are square, which can restrict the movement direction of the fourth slider 17. The fourth slider 17 is slidably arranged in both second blind grooves 16. The other ends of the two limiting rods 13 are respectively welded to the large surface of the corresponding fourth slider 17.

[0035] In this embodiment, the fourth slider 17 is squarely welded to the limiting rod 13 to match the second blind groove 16, which can maintain stable movement during the movement of the limiting rod 13 driven by the third slider 15.

[0036] Secondly, it also includes two fourth through holes 22, which are respectively opened on the corresponding fixing blocks 9. The fourth through holes 22 communicate with the first blind groove 14. The screw 18 is rotatably disposed in the first blind groove 14. The third slider 15 is connected to the screw 18 by a thread. A second connecting shaft 19 is welded to one end of the screw 18. The second connecting shaft 19 is rotatably disposed in the fourth through hole 22. A second rotating handle 20 is welded to one end of the second connecting shaft 19.

[0037] In addition, in this embodiment, the operator rotates the second handle 20 to drive the second connecting shaft 19 to rotate, the second connecting shaft 19 to drive the screw 18 to rotate, the screw 18 to drive the third slider 15 to slide in the first blind groove 14, the movement of the third slider 15 to drive the limit rod 13 to move, the movement of the limit rod 13 to drive the second slider 11 to move, thereby adjusting the position of the second sliders 11 on both sides to adapt to different models of I-beam guide rails.

[0038] Finally, see Figure 2 In this embodiment, two anti-wear pads 21 are also included. The two anti-wear pads 21 are respectively welded to the large surface of the corresponding first slider 6. The anti-wear pads 21 are made of wear-resistant and high-friction materials, such as powder metallurgy materials, which can provide wear resistance and anti-slip while also being resistant to high temperature and high pressure, so that the device can maintain good working performance in different environments.

[0039] Working principle:

[0040] When using this high-precision guide rail clamp, first place the clamp in the desired position. Then, when clamping the guide rail, the specific operation is as follows: First, the operator places the clamp on one end of the guide rail. Then, the operator adjusts the position of the second slider 11 according to the guide rail model. The operator then drags both sides of the second slider 11 until it engages with the notch in the guide rail. Next, the operator rotates the second handle 20, which drives the second connecting shaft 19 to rotate. The rotation of the second connecting shaft 19 drives the screw 18 to rotate, which in turn moves the third slider 15. The movement of the third slider 15 causes the limit rod 13 to move, which in turn causes the second slider 11 to move, thereby adjusting the position of the second sliders 11 on both sides to ensure that the device does not detach from the guide rail. Then, the high-precision guide rail clamp is slid to a suitable position. When it is necessary to clamp the guide rail, the operator rotates the first handle 8. The rotation of the first handle 8 causes the first connecting shaft 7 to rotate, which in turn causes the bidirectional lead screw 5 to rotate. The rotation of the bidirectional lead screw 5 causes the two first sliders 6 to move towards each other, which in turn causes the two anti-wear blocks to move towards each other, thereby clamping the guide rail and limiting the position of the workpiece.

[0041] 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.
