TECHNICAL FIELD
[0001] The present application relates to the technical field of machine tool guide rails, in particular to a guide rail strip plastic tape bonding device. BACKGROUND
[0002] Machine tool guide rails are important components on machine tools, used to support and guide the movement of moving parts. The material and performance of the guide rail have an important influence on the precision, stability and service life of the machine tool. Common guide rail materials include cast iron, steel and plastic, etc., among which plastic guide rails are widely used due to their good wear resistance, damping performance and process performance. The strip plastic tape, commonly known as guide rail soft tape, is a strip-shaped material made of polytetrafluoroethylene as the base material, with copper powder, molybdenum disulfide and graphite fillers mixed and sintered. The guide rail soft tape has good wear resistance, damping performance and process performance, and is suitable for various machine tool guide rail surfaces. It is usually bonded to the surface of the guide rail (metal plate) to improve the wear resistance of the guide rail. The assembly structure is shown in the accompanying drawings. Fig. 1-2
[0003] When bonding the strip plastic tape and the guide rail, it is necessary to press and paste to achieve the fastening and bonding of the two. Currently, the guide rail and the strip plastic tape connected by adhesive are directly assembled at the machine tool guide rail position, as shown in Fig. 2 , using the pressing force to bond the two, and after bonding, the guide rail can be directly used for linear driving. However, during the bonding process, the adhesive will overflow and adhere to the guide rail, the strip plastic tape and the machine tool. After the adhesive dries, it will affect the surface smoothness of the guide rail and the strip plastic tape, and thus affect the precision of the linear movement of the guide rail. Therefore, after pressing and fastening the guide rail and the strip plastic tape, it is necessary to disassemble them to remove the adhesive that has overflowed on the surface of the guide rail and the strip plastic tape, increasing the operation process. SUMMARY
[0004] In view of the above problems, the present application aims to provide a guide rail strip plastic tape bonding device that can achieve accurate bonding of the guide rail and the strip plastic tape, and at the same time solve the problem of adhesive overflow caused by direct pressing on the machine tool, which affects the linear running precision of the guide rail.
[0005] To achieve the above purpose, the technical solution adopted by the present application is as follows: a guide rail strip plastic tape bonding device, characterized in that the bonding device comprises a placement platform, a pressing mechanism for pasting the guide rail and the strip plastic tape is arranged on the placement platform, and a positioning mechanism that abuts against the guide rail and the strip plastic tape is arranged on the side wall of the placement platform.
[0006] Preferably, the placement platform has a bonding plane, a fastening screw is arranged at intervals on the bonding plane, and a pressing plate is sleeved on the fastening screw.
[0007] Preferably, the positioning mechanism comprises a positioning plate on the side wall of the placing platform, and the positioning plate is higher than the surface of the placing platform.
[0008] Preferably, a positioning screw is arranged on the positioning plate, and a pressing plate is arranged on the inner side of the positioning plate and connected to the end of the positioning screw, and the pressing plate is in contact with the end of the guide rail and the plastic strip at the same time.
[0009] The beneficial effects of the present application are: the adhesive device is used for placing the guide rail and the plastic strip horizontally during gluing, avoiding the problem of relative vertical sliding misalignment caused by different gravity of the two when placed vertically. The pressing mechanism can further press the guide rail and the plastic strip by external force, and a tight guide rail and plastic strip whole can be obtained after the adhesive solidifies. The positioning mechanism is used to drive the relative positioning of the guide rail and the plastic strip during the pressing process, thereby overcoming the problem of relative sliding misalignment of the guide rail and the plastic strip caused by adhesive under the pressing force. At the same time, the problem of adhesive overflow caused by direct pressing on the machine tool and the influence on the straight line running precision of the guide rail is solved.

[0022] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] See attached document Figs. 1-11 The present invention relates to a guide rail inlay plastic tape bonding device, which includes a placement platform 1, preferably horizontally arranged, for placing the guide rail and the inlay plastic tape horizontally during the bonding process, so as to avoid the problem of relative vertical sliding misalignment caused by the different gravity of the two when they are placed vertically.
[0024] The placement platform 1 is equipped with a pressing mechanism for attaching the guide rail 21 and the inlaid plastic strip 22. After the guide rail and the inlaid plastic strip, which are glued together (uncured), are placed horizontally on the placement platform 1, the pressing mechanism can be used to force the guide rail 21 and the inlaid plastic strip 22 to be further pressed together. After the adhesive is cured, a tight guide rail 21 and the inlaid plastic strip 22 can be obtained as a whole.
[0025] During the pressing process using the pressing mechanism, since the uncured adhesive is a flowable liquid, the guide rail 21 and the inlaid plastic strip 22 are prone to sliding and misaligning under the pressure of the external force. This results in a deviation in their relative positioning after bonding and curing, affecting the use of the guide rail. Therefore, to solve this problem, this application provides a positioning mechanism on the side wall of the placement platform 1 that abuts against the guide rail 21 and the inlaid plastic strip 22. This positioning mechanism drives the guide rail 21 and the inlaid plastic strip 22 to achieve relative positioning during the pressing process, thereby overcoming the problem of relative sliding and misalignment of the guide rail 21 and the inlaid plastic strip 22 due to the adhesive under the pressing force.
[0026] Specifically, such as Figs. 4-6 As shown, the placement platform 1 has an adhesive surface 1a, on which fastening screws 3 are spaced at intervals. The fastening screws 3 are preferably positioned at the center of the adhesive surface 1a, and a pressure plate 4 is fitted onto each fastening screw 3. When the fastening screws 3 are positioned at the center of the adhesive surface 1a, then... Fig. 6As shown, the placement and pressing operation of the guide rail 21 and the strip plastic 22 can be performed on the adhesive plane 1a located on both sides of the fastening screw 3, and the pressing plate 4 can be in pressing contact with the guide rail 21 and the strip plastic 22 placed on both sides under the fastening of the fastening screw 3 (in order to ensure the straightness of pressing, a pressing block 8 is further arranged at the bottom of the pressing plate 4), so that the pressing and fastening operation of multiple groups of guide rails 21 and strip plastics 22 can be realized in one pressing operation.
[0027] Specifically, as shown in Fig. 4 , 7 , the positioning mechanism includes a positioning plate 5 on the side wall of the placement platform 1, and the positioning plate 5 is higher than the surface of the placement platform 1. The positioning plate 5 is preferably arranged on the transverse side wall and the longitudinal side wall of the placement platform 1. In operation, the guide rail 21 and the strip plastic 22 coated with adhesive are placed on the adhesive plane 1a on one side of the fastening screw 3. Since the positioning plate 5 is higher than the surface of the placement platform 1, the side end and the side edge of the guide rail 21 and the strip plastic 22 are in abutment with the inner wall of the positioning plate 5, thereby achieving the limiting of the guide rail 21 and the strip plastic 22 in the adhesive state. Then, the pressing plate 4 is driven downward by the fastening screw 3, so that the pressing plate 4 is pressed on the guide rail 21 and the strip plastic 22, and after curing, the guide rail 21 and the strip plastic 22 can be removed.
[0028] In order to avoid the overflow of adhesive during the curing process, the guide rail 21 and the strip plastic 22 are preferably wrapped with a protective paper (not shown in the figure), and the adhesive that overflows is adhered by the protective paper. After curing, the protective paper is removed, thereby effectively avoiding the overflow of adhesive to the surface of the guide rail 21 and the strip plastic 22 and the influence on the adhesive plane 1a, and then the guide rail 21 and the strip plastic 22 after adhesive curing can be directly assembled on the machine tool for use.
[0029] Since the guide rail 21 and the strip plastic 22 to be adhered need to be placed on the adhesive plane 1a between the opposite positioning plates 5, there is a gap (as shown in Fig. 8 ) between the side end of the guide rail 21 and the strip plastic 22 and the adjacent positioning plate 5, so that the guide rail 21 and the strip plastic 22 can be smoothly placed. However, the gap will cause horizontal displacement and misalignment of the guide rail 21 and the strip plastic 22 during pressing, as shown in Fig. 9 , thereby affecting the relative positioning accuracy after the adhesion of the two, so as to solve the problem, as shown in Fig. 10 , a positioning screw 6 is arranged on the positioning plate 5, and a pressing plate 7 rotatably connected to the end of the positioning screw 6 is arranged on the inner side of the positioning plate 5, and the pressing plate 7 is in contact with the end of the guide rail 21 and the strip plastic 22. Fig. 10As shown, to avoid the end face of the strip plastic tape 22 in the later use process, the end of the strip plastic tape 22 is usually provided with a chamfer structure, so that the pressing plate 7 matches the chamfer structure, and the pressing plate 7 is lower than the surface of the strip plastic tape 22, avoiding the contact of the pressing plate 7 with the upper stacked strip plastic tape 22 (such as Fig. 11 As shown), and then after placing the guide rail 21 and the strip plastic tape 22 on the bonding plane 1a, the positioning screw 6 is rotated to drive the pressing plate 7 to simultaneously press and contact the end faces of the guide rail 21 and the strip plastic tape 22, which can effectively limit the sliding dislocation of the guide rail 21 and the strip plastic tape 22 under the action of the adhesive in the subsequent pressing process by the pressing plate 4, thereby further improving the positioning accuracy of the guide rail 21 and the strip plastic tape 22 after bonding.
[0030] The principle of the present application is that when the guide rail 21 and the strip plastic tape 22 are bonded, the guide rail 21 and the strip plastic tape 22 coated with adhesive are placed on the bonding plane 1a on one side of the fastening screw 3, then the positioning screw 6 is rotated to drive the pressing plate 7 to move and simultaneously contact the end of the guide rail 21 and the strip plastic tape 22, and then the pressing plate 4 is pressed to drive the guide rail 21 and the strip plastic tape 22 to solidify for a certain period of time, and then the assembly is disassembled and assembled on the machine tool for use.
[0031] The above shows and describes the basic principles, main features and advantages of the present application. Various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed application.
