Description

Technical Field

[0001] This utility model belongs to the field of cross rail fixing technology, and in particular relates to a cross rail fixing device with shock absorption function. Background Technology

[0002] Cross guide rails are a type of high-rigidity, high-precision finite linear motion system. By using R-type roller retainers that shorten the roller spacing, the effective contact length of the rollers is increased.

[0003] The patent application CN202321534485.3 discloses a drilling device for cross roller guides, including a drilling fixing device. The drilling fixing device has first storage slots on both sides of its inner walls. Multiple sets of first connecting plates are slidably connected to the inner sides of the first storage slots. The drilling fixing device also has second storage slots on both inner sides of its inner walls. Second connecting plates are slidably connected to the inner sides of the second storage slots. During operation, the drilling equipment can be used to drill cross roller guides. The overall device reduces the need to disassemble existing drilling fixing devices. Adjusting the adjusting devices installed on the drilling fixing devices to accommodate cross roller guides of different sizes is cumbersome and reduces work efficiency. The overall device improves the stability of drilling cross roller guides.

[0004] Although the aforementioned patent clamps and fixes the cross roller guide rail to facilitate drilling, the drilling process causes the surface of the cross roller guide rail to vibrate, resulting in a hard collision between the cross roller guide rail and the clamping component. This damages the cross roller guide rail and affects its surface smoothness and accuracy.

[0005] Therefore, how to provide a cross rail fixing device with shock absorption function is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a cross rail fixing device with shock absorption function, which aims to solve the problems mentioned in the background art.

[0007] This utility model is implemented as follows: a cross rail fixing device with shock absorption function, comprising;

[0008] Work platform;

[0009] A sliding rod, which is symmetrically slidably mounted on the top of the work platform;

[0010] A fixed inclined plate is fixedly installed on the inner side of the middle part of the slide bar;

[0011] A floating structure, wherein the floating structure is disposed in the middle of the slide bar;

[0012] A lifting ramp is movably mounted on the surface of the floating structure.

[0013] Preferably, the working platform is also provided with a traction structure to drive the slide rods to move in opposite directions, and an auxiliary clamping structure is provided in the middle to provide auxiliary clamping for the sides of the cross guide rails;

[0014] The traction structure includes a positioning plate and a second electric bidirectional screw. The positioning plate is symmetrically arranged at the left and right ends of the working platform, and the second electric bidirectional screw is symmetrically arranged at the front and rear ends of the positioning plate and is movably connected to the front and rear ends of the slide rod.

[0015] The auxiliary clamping structure includes a movable groove and a slider. The movable groove is located in the middle of the working platform, and a first electric bidirectional screw is movably installed in the middle. The slider is symmetrically arranged at the front and rear ends of the first electric bidirectional screw, and a clamping plate is fixedly installed on the top. A rubber pad is fixedly installed on the inner side of the clamping plate.

[0016] Preferably, the floating structure includes a limiting plate and a damper. The limiting plate is fixedly installed on the outer side of the middle part of the slide rod, and a lifting inclined block is slidably arranged on its surface. A first lifting groove is opened in the middle part of the slide rod. The damper array is arranged inside the first lifting groove, and a lifting plate is fixedly installed on the top, which movably abuts against the bottom of the lifting inclined block.

[0017] Preferably, the bottom of the clamping plate is provided with symmetrical sliding grooves, and the sliding rod is slidably disposed inside the sliding grooves.

[0018] Preferably, the power ends of both the first and second electric bidirectional screws are synchronous motors, and the first and second electric bidirectional screws are arranged in a staggered manner.

[0019] Preferably, a second lifting groove is provided on the inner side of the limiting plate, and guide rods are arranged in an array inside the second lifting groove, with the outer end of the lifting inclined block slidably disposed on the surface of the guide rods.

[0020] Preferably, the length of the lifting plate is equal to the length of the first lifting groove, and the width of the lifting plate is equal to the width of the first lifting groove.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, by setting a floating structure in the middle of the slide bar, the lifting inclined block is in a floating state, which in turn makes the cross guide rail placed on top of it suspended in a suspended state. This avoids damage to the surface of the work platform when drilling, and absorbs and reduces the impact generated by drilling. This prevents the lifting inclined block from hard colliding with the clamping component, which would cause damage and affect the surface smoothness and accuracy.

[0022] Meanwhile, by setting up a traction structure, the sliding rods at both ends are driven to move towards each other, so that the floating structure on the surface of the sliding rods can clamp and fix the two ends of the cross guide rail. An auxiliary clamping structure is also set up to clamp the two ends of the cross guide rail. With the cooperation of the floating structure, the cross guide rail is constrained and positioned, thereby improving the drilling accuracy and avoiding misalignment. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shown is a structural schematic of a cross rail fixing device with shock absorption function provided in one embodiment of the present invention, comprising:

[0033] Work platform 1;

[0034] Slide rod 8 is symmetrically slidable on the top of the work platform 1;

[0035] The fixed inclined plate 12 is fixedly installed on the inner side of the middle part of the slide bar 8;

[0036] A floating structure is provided, which is located in the middle of the slide bar 8.

[0037] Lifting ramp 19 is movably mounted on the surface of the floating structure.

[0038] In this embodiment of the utility model, when in use, a floating structure is set in the middle of the slide bar 8, so that the lifting inclined block 19 is in a floating state, and the cross guide rail placed on its top is in a suspended state. This avoids damage to the surface of the work platform 1 when drilling, and absorbs and reduces the impact generated by drilling. This prevents the lifting inclined block 19 from hard collision with the clamping component, which would cause damage and affect the surface smoothness and accuracy.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the working platform 1 is also provided with a traction structure to drive the slide bar 8 to move in opposite directions, and an auxiliary clamping structure is provided in the middle to provide auxiliary clamping for the side of the cross guide rail.

[0040] The traction structure includes a positioning plate 10 and a second electric bidirectional screw 7. The positioning plate 10 is symmetrically arranged at the left and right ends of the working platform 1, and the second electric bidirectional screw 7 is symmetrically arranged at the front and rear ends of the positioning plate 10 and is movably connected to the front and rear ends of the slide bar 8.

[0041] The auxiliary clamping structure includes a movable groove 2 and a slider 4. The movable groove 2 is located in the middle of the working platform 1, and a first electric bidirectional screw 3 is movably installed in the middle. The slider 4 is symmetrically arranged at the front and rear ends of the first electric bidirectional screw 3, and a clamping plate 5 is fixedly installed on the top. A rubber inner pad 11 is fixedly installed on the inner side of the clamping plate 5.

[0042] In this embodiment of the utility model, when in use, the synchronous motor 9 at the outer end of the second electric bidirectional screw 7 is started, thereby causing the slide bar 8 to move away from the positioning plate 10, and then the floating structure lifts and fixes the two ends of the cross guide rail. Then the synchronous motor 9 of the first electric bidirectional screw 3 in the movable groove 2 is started, and then the slider 4 drives the clamping plates 5 to move closer to each other, so that the rubber inner pad 11 abuts against the side of the lifted cross guide rail.

[0043] By setting up a traction structure and an auxiliary clamping structure, the cross guide rail can be fixed in multiple directions, thereby avoiding misalignment during drilling and preventing a decrease in drilling accuracy.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the floating structure includes a limiting plate 13 and a damper 15. The limiting plate 13 is fixedly installed on the outer side of the middle part of the slide rod 8, and a lifting inclined block 19 is slidably arranged on its surface. A first lifting groove 14 is opened in the middle part of the slide rod 8. The damper 15 is arranged in an array inside the first lifting groove 14, and a lifting plate 16 is fixedly installed on the top, which movably abuts against the bottom of the lifting inclined block 19.

[0045] In this embodiment of the utility model, when in use, the two sliding rods 8 move towards the middle, thereby causing the fixed inclined plate 12 to lift up both ends of the cross guide rail, thereby causing the cross guide rail to move to the top of the lifting inclined block 19, and then abut against the limiting plate 13.

[0046] By setting up a floating structure, the cross guide rails are kept suspended, thus preventing damage to the surface of the work platform 1 during drilling.

[0047] like Figure 1 , Figure 2 and Figure 4As shown, in a preferred embodiment of the present invention, the bottom of the clamping plate 5 is provided with symmetrical sliding grooves 6, and the sliding rod 8 is slidably disposed inside the sliding grooves 6.

[0048] In this embodiment of the utility model, when in use, the bottom of the clamping plate 5 is symmetrically provided with sliding grooves 6, and the sliding rod 8 is slidably disposed inside the sliding grooves 6, thereby avoiding obstruction when the clamping plate 5 or the sliding rod 8 moves, thus preventing the normal clamping from being affected.

[0049] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment of the present invention, the power ends of both the first electric bidirectional screw 3 and the second electric bidirectional screw 7 are synchronous motors 9, and the first electric bidirectional screw 3 and the second electric bidirectional screw 7 are arranged in a staggered manner.

[0050] In this embodiment of the invention, when in use, by using synchronous motors 9 at the power ends of both the first electric bidirectional screw 3 and the second electric bidirectional screw 7, the second electric bidirectional screw 7 can move synchronously, and the first electric bidirectional screw 3 can start with a delay. By setting the first electric bidirectional screw 3 and the second electric bidirectional screw 7 to be cross-staggered, it is convenient to clamp the cross guide rail in multiple directions.

[0051] like Figure 1 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, a second lifting groove 17 is provided on the inner side of the limiting plate 13, and a guide rod 18 is arranged in an array inside the second lifting groove 17. The outer end of the lifting inclined block 19 is slidably disposed on the surface of the guide rod 18.

[0052] In this embodiment of the utility model, when in use, a second lifting groove 17 is provided on the inner side of the limiting plate 13, and then a guide rod 18 is arranged in an array inside the second lifting groove 17, so that the outer end of the lifting inclined block 19 is slidably placed on the surface of the guide rod 18, thereby allowing the lifting inclined block 19 to move up and down.

[0053] like Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the length of the lifting plate 16 is equal to the length of the first lifting groove 14, and the width of the lifting plate 16 is equal to the width of the first lifting groove 14.

[0054] In this embodiment of the utility model, when in use, the length of the lifting plate 16 is equal to the length of the first lifting groove 14, and the width of the lifting plate 16 is equal to the width of the first lifting groove 14, thereby facilitating the entry and exit of the lifting plate 16 into and out of the first lifting groove 14.

[0055] The present invention provides a cross rail fixing device with shock absorption function in the above embodiment. When in use, the cross rail is placed on the surface of the work platform 1, and then the synchronous motor 9 at the outer end of the second electric bidirectional screw 7 is started, so that the slide bar 8 moves away from the positioning plate 10 and moves along the slide groove 6 at the bottom of the clamping plate 5, thereby causing the fixing inclined plate 12 to lift up both ends of the cross rail, thereby causing the cross rail to move to the top of the lifting inclined block 19 and then abut against the limiting plate 13, so that the cross rail is in a suspended state, thereby avoiding damage to the surface of the work platform 1 when drilling.

[0056] Then, the synchronous motor 9 of the first electric bidirectional screw 3 in the active slot 2 is started, which in turn drives the clamping plates 5 to move closer to each other through the slider 4, so that the rubber inner pad 11 abuts against the side of the lifted cross guide rail, thereby constraining and positioning the cross guide rail.

[0057] During the drilling process, an impact is applied to the cross guide rail, causing the lifting ramp 19 to descend along the surface of the guide rod 18 in the second lifting groove 17 and apply pressure to the lifting plate 16, which then enters the first lifting groove 14 and applies pressure to the damper 15 in the first lifting groove 14, thereby absorbing and reducing the impact generated by the drilling.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
