[0031] In order to have the ability of long stroke and wide range of use, long guide rails are usually used to meet the requirements in large-scale automation equipment, and the length of the guide rail determines the use stroke range of the equipment.

[0032] In the related art, the following two ways are usually used to lengthen the guide rail length: first, a whole length longer guide rail is used, which has great manufacturing difficulty and is difficult to ensure precision; second, at least two guide rails are spliced together by screws, which requires a positioning shoulder on one side of the guide rail and an additional auxiliary positioning block and a locking screw on the other side, so as to position the spliced guide rails under the cooperation of the positioning shoulder, the auxiliary positioning block and the locking screw. The structure is complex, the positioning adjustment is tedious, the guide rail splicing and installation speed is slow, and the positioning precision is difficult to guarantee.

[0033] Based on the above problems, the utility model provides a positioning piece 10, which aims to achieve the effects of rapid splicing and accurate positioning.

[0034] Please refer to Figures 1 to 5 In an embodiment of the utility model, the positioning piece 10 is used for positioning two adjacent guide rails 20, the guide rail 20 is provided with a splicing surface 21, the splicing surface 21 is provided with a splicing groove 22, the splicing surfaces 21 of the two adjacent guide rails 20 are butted, the two splicing grooves 22 form a splicing groove 22a, the positioning piece 10 is configured to be inserted into the splicing groove 22a, and the outer side wall of the positioning piece 10 is configured to abut against the groove side wall of the splicing groove 22a.

[0035] The utility model discloses a technical scheme adopts at least two guide rails 20 to lengthen guide rail 20 length, first at least two guide rails 20 are arranged along the first direction, because the splicing surface 21 of guide rail 20 is equipped with splicing recess 22, when the mutual splicing of adjacent two guide rails 20, can make the splicing recess 22 of one of guide rail 20 and the splicing recess 22 of another guide rail 20 form complete splicing groove 22a, at this time, adopt positioning member 10 and insert in splicing groove 22a, and make the outside wall of positioning member 10 and the groove lateral wall of splicing groove 22a abut, then, when the misplacement of adjacent two guide rails 20 occurs, in the process of inserting positioning member 10 in splicing groove 22a, can adjust the misplacement guide rail 20 through positioning member 10 to carry out accurate positioning to adjacent two guide rails 20. Therefore, the scheme cancels the positioning shoulder of guide rail 20 installation, the use of auxiliary positioning block and tight screw, and adopts positioning member 10 to combine the splicing groove 22a on guide rail 20 to carry out accurate positioning to the splicing guide rail 20, so that when guide rail 20 is installed, the effect of quick splicing and accurate positioning can be achieved, and when guide rail 20 is reorganized and installed, the effect of quick splicing and accurate positioning can also be achieved. And, because the scheme cancels the positioning shoulder of guide rail 20 installation, the use of auxiliary positioning block and tight screw, makes the structure simple, and the parts are few, reduces the number of parts of guide rail 20 splicing and the requirement to installation space, and also more convenient to disassemble, thereby improving the assembly efficiency when the guide rail 20 is spliced and reorganized, reducing the difficulty of guide rail 20 in the transportation process, suitable for small space occasions in automatic equipment, and expanding the application scenarios of spliced guide rail 20.

[0036] In addition, compared with using a whole guide rail 20 with a longer length to have the ability of long stroke and wide range use, the scheme can solve the problems of great manufacturing difficulty and difficult to ensure precision by splicing at least two guide rails 20 and positioning member 10 to form a longer guide rail 20.

[0037] In summary, the scheme adopts the plug-in structure of high-precision positioning member 10, reduces the number of parts of guide rail 20 splicing and the requirement to installation space, improves the assembly efficiency when the guide rail 20 is reorganized and spliced, reduces the difficulty of guide rail 20 in the transportation process, and expands the application scenarios of spliced guide rail 20.

[0038] In actual application process, the outer contour shape of positioning member 10 can be a cylinder, a prism and the like, and correspondingly, the cross section of splicing recess 22 of guide rail 20 can be semicircular, square, prismatic, V-shaped and the like, as long as the splicing groove 22a formed by positioning member 10 and two splicing recesses 22 is matched.

[0039] In addition, the splicing recess 22 of guide rail 20 can penetrate the bottom of guide rail 20, or can not penetrate the bottom of guide rail 20.

[0040] In actual application process, the positioning piece 10 is used to position two adjacent guide rails 20, and after the guide rails 20 are fixed, the positioning piece 10 can be taken out from the splicing groove 22a to be used to position another two guide rails 20. Of course, the positioning piece 10 can also be retained in the splicing groove 22a.

[0041] In some embodiments, after the positioning piece 10 is used to position two adjacent guide rails 20, the guide rails 20 can be fixed on the base or support of the automatic equipment by using the fastening screw 30.

[0042] In some embodiments, the guide rail 20 can be provided with a sliding block 40, and the sliding block 40 is used to connect with a carrier, and when the sliding block 40 slides along the length direction of the guide rail 20, the carrier can be driven to slide.

[0043] Please refer to Figure 1 , Figure 4 , Figure 5 In an embodiment of the utility model, the top of the positioning piece 10 is provided with a matching hole 11, and the matching hole 11 is configured to cooperate with an auxiliary piece.

[0044] In this way, after the positioning piece 10 is inserted into the splicing groove 22a between two adjacent guide rails 20, in order to prevent the positioning piece 10 from interfering with other components (such as the sliding block 40), the positioning piece 10 generally does not protrude from the top of the guide rail 20, and therefore the auxiliary piece is inserted into the matching hole 11 of the positioning piece 10, so that the auxiliary piece can protrude from the top of the guide rail 20, and the user can take the auxiliary piece to pull out or push out the positioning piece 10, thereby facilitating the assembly and disassembly of the positioning piece 10; and when the guide rail 20 is re-spliced, the user can also take the auxiliary piece to support and adjust the positioning piece 10, thereby simplifying the splicing difficulty of the guide rail 20. In addition, after the guide rail 20 is re-spliced, the auxiliary piece can be taken out from the matching hole 11 of the positioning piece 10 to prevent the auxiliary piece from interfering with other components (such as the sliding block 40).

[0045] In actual application process, the matching hole 11 can be a threaded hole or a light hole, and correspondingly, the auxiliary piece can be a screw or a columnar structure, that is, the auxiliary piece and the matching hole 11 can be threadedly matched or interference-fitted. In addition, the matching hole 11 can penetrate the bottom of the positioning piece 10 or not.

[0046] In actual application process, the auxiliary piece can be a handheld piece or an auxiliary tool.

[0047] Please refer to Figure 1 , Figure 4 , Figure 5In an embodiment of the present application, the cooperation hole 11 is a threaded hole, the auxiliary part is a screw, and the threaded hole is configured to cooperate with the screw.

[0048] In this way, the screw can be directly screwed into the threaded hole of the positioning piece 10, so that the user can take the screw to pull out or push out the positioning piece 10, thereby facilitating the assembly and disassembly of the positioning piece 10; and when the guide rail 20 is reassembled, the user can also take the screw to support and adjust the positioning piece 10, thereby simplifying the assembly difficulty of the guide rail 20. In addition, after the guide rail 20 is reassembled, the screw can be unscrewed from the threaded hole of the positioning piece 10 to prevent the screw from interfering with other components (such as the slider 40). Therefore, by cooperating the screw with the threaded hole, the connection reliability between the screw and the positioning piece 10 can be improved, and the installation and disassembly of the screw are also facilitated.

[0049] Please refer to Figure 1 , Figure 4 , Figure 5 In an embodiment of the present application, the threaded hole penetrates from the top of the positioning piece 10 to the bottom of the positioning piece 10.

[0050] In this way, when the screw is screwed into the threaded hole of the positioning piece 10, the screw and the positioning piece 10 can have a sufficient locking length, thereby further improving the connection reliability between the screw and the positioning piece 10.

[0051] Please refer to Figures 1 to 3 In an embodiment of the present application, the outer contour of the positioning piece 10 is a cylinder, and the cross section of the splicing groove 22 is semicircular.

[0052] In this way, the design of the cylinder and the semicircle is more convenient to form than other shapes, and the risk of stress is low, thereby ensuring the strength of the positioning piece 10 and the guide rail 20, and further prolonging the service life of the positioning piece 10 and the guide rail 20.

[0053] Please refer to Figure 1 , Figure 4 , Figure 5 In an embodiment of the present application, the positioning piece 10 is provided with a guide surface 12 on the outer side, and the guide surface 12 is arranged close to the bottom of the positioning piece 10.

[0054] In this way, the design of the guide surface 12 can guide the positioning piece 10 into the splicing groove 22a, so as to facilitate the insertion of the positioning piece 10 into the splicing groove 22a, thereby reducing the operation difficulty and improving the positioning efficiency of the guide rail 20.

[0055] In some embodiments, the guide surface 12 is a guide conical surface, and the angle of the guide conical surface can not be specifically limited, for example, it can be 15°, 16°, 17°, 18°, 19°, etc.

[0056] Referring to Figure 1 In an embodiment of the present application, the hardness HRC of the positioning member 10 is greater than 55.

[0057] In this way, the positioning member 10 is heat treated and hardened on the outer surface, so that the hardness HRC of the positioning member 10 is greater than 55, which can improve the wear resistance of the positioning member 10, prolong the service life of the positioning member 10, and ensure the accuracy retention of the positioning member 10 during repeated disassembly and assembly.

[0058] In some embodiments, the positioning member 10 can be ground and finished to accurately control the size of the positioning member 10, so as to ensure the assembly precision between the positioning member 10 and the splicing groove 22a of the guide rail 20, and still maintain high precision requirements under the condition of repeatedly pulling and inserting the positioning member 10.

[0059] Referring to Figures 2 to 5 The present application also provides a guide rail assembly 100, which comprises the positioning member 10 and at least two guide rails 20.

Since the guide rail assembly 100 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0060] Among them, the at least two guide rails 20 are arranged along the first direction, and the adjacent two guide rails 20 are spliced with each other. The splicing surface 21 of the guide rail 20 is provided with a splicing groove 22, and the splicing groove 22 of one guide rail 20 and the splicing groove 22 of another guide rail 20 form a splicing groove 22a. The splicing groove 22a is inserted with a positioning member 10, and the outer side wall of the positioning member 10 abuts against the groove side wall of the splicing groove 22a.

[0061] It can be understood that when the at least two guide rails 20 are used to lengthen the length of the guide rail 20, the at least two guide rails 20 are first arranged in the first direction, and since the splicing surface 21 of the guide rail 20 is provided with the splicing groove 22, when the two adjacent guide rails 20 are spliced with each other, the splicing groove 22 of one of the guide rails 20 and the splicing groove 22 of the other guide rail 20 form a complete splicing groove 22a, at this time, the positioning piece 10 is inserted into the splicing groove 22a, and the outer side wall of the positioning piece 10 abuts against the groove side wall of the splicing groove 22a, then when the two adjacent guide rails 20 are misaligned, during the process that the positioning piece 10 is inserted into the splicing groove 22a, the misaligned guide rails 20 can be adjusted by the positioning piece 10, so as to accurately position the two adjacent guide rails 20. Therefore, the scheme cancels the use of the positioning shoulder, the auxiliary positioning block and the fixing screw for the installation of the guide rail 20, and the positioning piece 10 combined with the splicing groove 22a on the guide rail 20 can accurately position the spliced guide rail 20, so that the effect of quick splicing and accurate positioning can be achieved during the installation of the guide rail 20, and the effect of quick splicing and accurate positioning can also be achieved during the reinstallation of the guide rail 20.

[0062] Please refer to Figure 4 、 Figure 5 In an embodiment of the present application, the top surface of the positioning piece 10 is lower than the top surface of the guide rail 20.
