Description

Technical Field

[0001] The utility model relates to the field of guide rail processing and butt joint, in particular to a butt joint device for guide rail processing. Background Technique

[0002] The guide rail, also known as the slide rail, linear guide rail, and linear slide rail, is used in occasions of linear reciprocating motion and has a higher rated load than linear bearings. The guide rail can be set in the shape of T, I, king-shaped, etc., and is mainly used to guide and fix machine components, special equipment, instruments, etc.

[0003] When the length of the guide rail is insufficient, it is necessary to butt and assemble two identical guide rails. During the processing operation, it is necessary to align the end faces of two adjacent guide rails, and then fix the end faces of two adjacent guide rails by bolts or welding, so that two adjacent guide rails are connected together to form a whole. However, during the processing and butt joint process, in order to ensure the butt joint quality, it is necessary to accurately and closely align the ends of the end faces of the two guide rails. In the prior art, it is often manually aligned by hand, and then the two guide rails are fixed by a fixture. However, during this process, once the guide rail is clamped and fixed, the guide rail cannot be moved and adjusted. When there is a displacement misalignment or a gap between the end faces of the two guide rails, the positions of the two guide rails cannot be adjusted. At this time, it is necessary to disengage the fixture from the guide rail and repeatedly debug the position of the guide rail. After the guide rail is debugged, the guide rail is fixed by the fixture again, and the operation is relatively inconvenient.

[0004] Therefore, it is very necessary to invent a butt joint device for guide rail processing. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems raised in the above background technique.

[0006] In order to achieve the above purpose, the utility model provides the following technical scheme: A butt joint device for guide rail processing, including an I-shaped guide rail and a butt joint auxiliary mechanism. The butt joint auxiliary mechanism includes a positioning seat and protective boxes symmetrically installed at the upper ends on both sides of the positioning seat. A moving groove is opened on one side of the protective box, an adjusting component is installed in the inner cavity of the protective box, one side of the adjusting component is connected with a scissor-type telescopic arm, and first clamping components and second clamping components are installed on both sides of the end of the scissor-type telescopic arm away from the adjusting component.

[0007] Based on the above features: two adjacent I-shaped guide rails are placed opposite to each other on the positioning seat, and then the end faces of the two adjacent I-shaped guide rails are initially fitted together manually. At this time, the adjustment component can drive the scissors-type telescopic arm to move, so that the scissors-type telescopic arm drives the first clamping component and the second clamping component to telescope and adjust. At this time, the first clamping component can center clamp one of the I-shaped guide rails, and the second clamping component can center clamp the other I-shaped guide rail, so as to avoid offset and misalignment of the two adjacent I-shaped guide rails during docking processing.

[0008] Preferably, movable holes are provided at intervals on the upper end surface of the positioning seat, and balls are provided inside the movable holes.

[0009] Based on the above characteristics: when the I-shaped guide rail is moved above the positioning seat, the ball can rotate inside the movable hole, so that rolling friction can be formed between the I-shaped guide rail and the positioning seat, which facilitates the movement and adjustment of the I-shaped guide rail.

[0010] Preferably, the adjustment assembly includes a forward and reverse screw and a bearing seat A symmetrically installed at both ends of the forward and reverse screw, and movable nuts are threadedly connected to the outer sides of the forward and reverse screw, and a lug is installed on one side of the outer wall of the movable nut.

[0011] Based on the above characteristics: when the scissors-type telescopic arms are merged, the scissors-type telescopic arms will drive the first clamping assembly and the second clamping assembly to extend; when the scissors-type telescopic arms are opened, the scissors-type telescopic arms will drive the first clamping assembly and the second clamping assembly to retract, thereby allowing the first clamping assembly and the second clamping assembly to be telescopically adjusted to center the I-shaped guide rail.

[0012] Preferably, the first clamping assembly includes a clamp plate A and a fixed block A fixedly installed on one side of the clamp plate A, a slot A is provided on a side of the clamp plate A away from the fixed block A, and a limiting protrusion is fixedly installed in the middle of a side of the slot A close to the fixed block A.

[0013] Based on the above features: when clamp A is driven to extend, clamp A can use slot A to clamp and limit the two sides of one of the I-shaped guide rails. During this process, the limiting protrusion can be inserted into the groove on the side of the I-shaped guide rail to prevent the I-shaped guide rail from moving upward after being clamped in the center, thereby improving the fixing effect.

[0014] Preferably, the second clamping assembly includes a clamping plate B and a fixing block B fixedly installed on one side of the clamping plate B, a slot B is provided on a side of the clamping plate B away from the fixing block B, and a roller is provided between the clamping plate B and the fixing block B.

[0015] Based on the above features: When the clamping plate B is driven to extend, the clamping plate B can use the slot B to clamp and limit the two sides of another I-shaped guide rail. During this process, the roller can be inserted into the slots on the sides of the I-shaped guide rail. When there is a gap between the end faces of the two I-shaped guide rails and they are not close enough, the roller can drive the I-shaped guide rail clamped by the clamping plate B to move, so that the I-shaped guide rail is closely attached to another I-shaped guide rail. At the same time, due to the limitation of the roller, the I-shaped guide rail can maintain translation and will not become disengaged.

[0016] Preferably, a through groove is formed in the middle of one side of the clamping plate B close to the fixed block B, and the roller movably penetrates through the through groove.

[0017] Based on the above features: The roller is arranged on one side of the inner cavity of the fixed block B. At the same time, one side of the roller can penetrate through the middle of one side of the clamping plate B through the through groove. When the clamping plate B clamps the I-shaped guide rail, one side of the roller can be inserted into the slot on the side of the I-shaped guide rail, and at the same time, rolling friction is formed between the roller and the side of the I-shaped guide rail.

[0018] Preferably, a bearing seat B is arranged at the bottom of the roller, a rotating shaft is installed in the middle of the roller, and a micro motor is installed at the upper end of the rotating shaft. The micro motor is located at the upper end of the outside of the fixed block B.

[0019] Based on the above features: After the micro motor is started, it can drive the roller to rotate through the rotating shaft. When the roller rotates, the roller can drive the I-shaped guide rail clamped by the clamping plate B to move.

[0020] The beneficial effects of the present utility model are:

[0021] 1. It can avoid the situation that two adjacent I-shaped guide rails are offset and misaligned during butt joint processing. When two adjacent I-shaped guide rails are placed opposite each other on the positioning seat, the end faces of the two adjacent I-shaped guide rails can be first attached together. When the positive and negative screw is driven to rotate forward or backward for adjustment, the movable nut can move in opposite directions on both sides of the positive and negative screw. When the movable nut drives the scissor-type telescopic arm to close, the scissor-type telescopic arm will drive the clamping plate A and the clamping plate B to extend. When the movable nut drives the scissor-type telescopic arm to open, the scissor-type telescopic arm will drive the clamping plate A and the clamping plate B to retract. At this time, the clamping plate A can use the slot A to clamp and limit the two sides of one I-shaped guide rail, and the clamping plate B can use the slot B to clamp and limit the two sides of another I-shaped guide rail, which is convenient for the clamping plate A and the clamping plate B to quickly center and clamp the two I-shaped guide rails.

[0022] 2. When the clamping plate A clamps and fixes one of the I-shaped guide rails, the limit lug can be inserted into the slot on the side of the I-shaped guide rail, preventing the I-shaped guide rail from moving on its own. When the clamping plate B clamps and fixes the other I-shaped guide rail, the roller can be inserted into the slot on the side of the I-shaped guide rail, forming a rolling friction between the roller and the side of the I-shaped guide rail. When there is a gap between the end faces of the two I-shaped guide rails and they are not close enough, the micro-motor can drive the roller to rotate through the rotating shaft. At this time, the roller can drive the I-shaped guide rail clamped by the clamping plate B to move, making the I-shaped guide rail fit tightly with the other I-shaped guide rail.

[0029] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not intended to limit the present utility model.

[0030] Refer to the attached Figures 1-5, A docking device for rail processing provided by the utility model includes an I-shaped rail and a docking auxiliary mechanism. The docking auxiliary mechanism includes a positioning seat 1 and protective boxes 2 symmetrically installed at the upper ends on both sides of the positioning seat 1. A moving groove 3 is opened on one side of the protective box 2. An adjusting component 4 is installed in the inner cavity of the protective box 2 (the protective box 2 can protect the outside of the adjusting component 4). One side of the adjusting component 4 is connected to a scissor-type telescopic arm 5. On both sides of the end of the scissor-type telescopic arm 5 away from the adjusting component 4, a first clamping component 6 and a second clamping component 7 are installed (the opened moving groove 3 can limit the first clamping component 6 and the second clamping component 7, facilitating the parallel movement of the first clamping component 6 and the second clamping component 7).

[0031] Place two adjacent I-shaped rails opposite to each other on the positioning seat 1. Subsequently, manually and preliminarily fit the end faces of the two adjacent I-shaped rails together by hand. At this time, the adjusting component 4 can drive the scissor-type telescopic arm 5 to move, so that the scissor-type telescopic arm 5 drives the first clamping component 6 and the second clamping component 7 to expand and contract. At this time, the first clamping component 6 can clamp one of the I-shaped rails in the center, and the second clamping component 7 can clamp the other I-shaped rail in the center, trying to avoid the situation of offset and misalignment when two adjacent I-shaped rails are butt-jointed and processed.

[0032] Preferably, movable holes 11 are spaced apart on the upper surface of the positioning seat 1, and balls 12 are arranged inside the movable holes 11.

[0033] When the I-shaped rail moves above the positioning seat 1, the balls 12 can rotate inside the movable holes 11, so that rolling friction can be formed between the I-shaped rail and the positioning seat 1, facilitating the movement and adjustment of the I-shaped rail.

[0034] Preferably, the adjusting component 4 includes a positive and reverse screw rod 41 and bearing seats A42 symmetrically installed at both ends of the positive and reverse screw rod 41. Movable nuts 43 are threadedly connected to both sides of the outside of the positive and reverse screw rod 41, and a lug 44 is installed on one side of the outer wall of the movable nut 43.

[0035] The positive and reverse screw rod 41 can be manually rotated by a handle or electrically driven by a motor. This application does not make a limitation and can be set according to needs. When the positive and reverse screw rod 41 is driven to rotate forward or reverse for adjustment, the movable nuts 43 can move towards each other on both sides of the positive and reverse screw rod 41. The movable nuts 43 are movably hinged to both sides of one end of the scissor-type telescopic arm 5 by means of the lugs 44, facilitating the movable nuts 43 to drive the scissor-type telescopic arm 5 to close and open. When the scissor-type telescopic arm 5 closes, the scissor-type telescopic arm 5 will drive the first clamping component 6 and the second clamping component 7 to extend. When the scissor-type telescopic arm 5 opens, the scissor-type telescopic arm 5 will drive the first clamping component 6 and the second clamping component 7 to retract, so that the first clamping component 6 and the second clamping component 7 can be adjusted by expansion and contraction to clamp the I-shaped rail in the center.

[0036] Preferably, the first clamping assembly 6 includes a clamping plate A61 and a fixing block A62 fixedly installed on one side of the clamping plate A61. A slot A63 is formed on the side of the clamping plate A61 away from the fixing block A62, and a limiting projection 64 is fixedly installed in the middle of the side of the slot A63 close to the fixing block A62.

[0037] The clamping plate A61 is movably hinged to one end of the scissor-type telescopic arm 5 by means of the fixing block A62. When the clamping plate A61 is driven to extend, the clamping plate A61 can clamp and limit the two sides of one of the I-shaped guide rails by using the slot A63. During this process, the limiting projection 64 can be inserted into the slot on the side of the I-shaped guide rail to prevent the I-shaped guide rail from moving upward after being centered and clamped, thereby improving the fixing effect.

[0038] Preferably, the second clamping assembly 7 includes a clamping plate B71 and a fixing block B72 fixedly installed on one side of the clamping plate B71. A slot B73 is formed on the side of the clamping plate B71 away from the fixing block B72, and a roller 74 is arranged between the clamping plate B71 and the fixing block B72.

[0039] The clamping plate B71 is movably hinged to the other end of the scissor-type telescopic arm 5 by means of the fixing block B72. When the clamping plate B71 is driven to extend, the clamping plate B71 can clamp and limit the two sides of the other I-shaped guide rail by using the slot B73. During this process, the roller 74 can be inserted into the slot on the side of the I-shaped guide rail. When there is a gap between the end faces of the two I-shaped guide rails and they are not close enough, the roller 74 can drive the I-shaped guide rail clamped by the clamping plate B71 to move, so that the I-shaped guide rail is closely attached to the other I-shaped guide rail. At the same time, due to the limitation of the roller 74, the I-shaped guide rail can maintain translation and will not become detached.

[0040] Preferably, a through groove 711 is formed in the middle of the side of the clamping plate B71 close to the fixing block B72, and the roller 74 movably penetrates through the through groove 711.

[0041] The roller 74 is arranged on one side of the inner cavity of the fixing block B72. At the same time, one side of the roller 74 can penetrate through the middle of one side of the clamping plate B71 through the through groove 711. When the clamping plate B71 clamps the I-shaped guide rail, one side of the roller 74 can be inserted into the slot on the side of the I-shaped guide rail, and at the same time, a rolling friction is formed between the roller 74 and the side of the I-shaped guide rail.

[0042] Preferably, a bearing seat B741 is arranged at the bottom of the roller 74, a rotating shaft 742 is installed in the middle of the roller 74, and a micro motor 743 is installed at the upper end of the rotating shaft 742. The micro motor 743 is located at the upper outer end of the fixing block B72.

[0043] The bearing seat B741 can support the lower end of the roller 74. After the micro motor 743 is started, the roller 74 can be driven to rotate by the rotating shaft 742. When the roller 74 rotates, the roller 74 can drive the I-shaped guide rail clamped by the clamping plate B71 to move.

[0044] The using process of the utility model is as follows: during the docking operation, two adjacent I-shaped guide rails are placed opposite to each other on the positioning seat 1. Subsequently, the end faces of the two adjacent I-shaped guide rails are manually and preliminarily fitted together. When the positive and reverse screw 41 is driven to rotate forward or backward for adjustment, the movable nut 43 can move in opposite directions on both sides of the positive and reverse screw 41. When the movable nut 43 drives the scissor-type telescopic arm 5 to close, the scissor-type telescopic arm 5 will drive the clamping plate A61 and the clamping plate B71 to extend. When the movable nut 43 drives the scissor-type telescopic arm 5 to open, the scissor-type telescopic arm 5 will drive the clamping plate A61 and the clamping plate B71 to retract. At this time, the clamping plate A61 can use the slot A63 to clamp and limit the two sides of one of the I-shaped guide rails. During this process, the limiting bump 64 can be inserted into the slot on the side of the I-shaped guide rail, and the clamping plate B71 can use the slot B73 to clamp and limit the two sides of the other I-shaped guide rail. During this process, the roller 74 can be inserted into the slot on the side of this I-shaped guide rail. When there is a gap between the end faces of the two I-shaped guide rails and they are not tight enough, the micro motor 743 can drive the roller 74 to rotate through the rotating shaft 742. At this time, the roller 74 can drive the I-shaped guide rail clamped by the clamping plate B71 to move, so that this I-shaped guide rail is closely fitted with the other I-shaped guide rail.

[0045] The above is only the preferred embodiment of the utility model. Any person skilled in the art may modify the utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the utility model falls within the scope of protection required by the utility model.
