[0024] The present application provides a guide rail installation tool for a needle bed base, comprising a positioning installation part 2 straddling the two installation end surfaces of the needle bed base 1, a connecting part 3 extending along the length direction of the needle bed base 1 and fixedly connected to the positioning installation part 2; a track detection bracket 4 extending from the connecting part 3, and a track detection device 5 extending from the track detection bracket 5. The guide rail installation tool is abutted against the two installation end surfaces of the needle bed base 1 through the positioning installation part 2, and is connected to the positioning installation part 2 as a whole through the connecting part 3. The dual-system needle bed base 1 has two relatively inclined needle plate installation end surfaces, and the positioning installation part 2 is respectively abutted against the two installation end surfaces, and abutted against the two installation end surfaces in a straddling manner to ensure the stability of the placement position of the guide rail installation tool above the needle bed base 1. Multiple track detection brackets 4 can be extended from the connecting part 3 along the length direction, and a track detection device 5 is arranged on the track detection bracket 4. Then, the track detection device 5 can detect the straightness of the guide rail in a multi-point detection manner in the length direction, so that the guide rail can be positioned and detected along the length direction to ensure the consistency of the detection result.
[0025] In a specific embodiment of the present case, the positioning and mounting portion 2 includes a plurality of positioning and mounting frames arranged at intervals, and a plurality of supporting feet 24 extending from the positioning and mounting frames respectively fit tightly with two mounting end surfaces, and the supporting feet 24 have supporting end surfaces that are flush with the mounting end surfaces.
[0026] The positioning mounting frame includes a first supporting arm 21 and a second supporting arm 22 respectively parallel to two mounting end surfaces, and a connecting arm 23 connecting the two; a plurality of supporting feet 24 are disposed on the first supporting arm 21 and the second supporting arm 22 .
[0027] Preferably, the first support arm 21 and the second support arm 22 are arranged with two groups of support feet 24 arranged in pairs along the extension direction of the first support arm 21 and the second support arm 22 .
[0028] The needle bed base 1 has a dual-system needle plate structure, and the two needle plate mounting end faces 11 are arranged inclined to each other and form an overall trapezoidal structure. Using this trapezoidal structure, the positioning mounting frame is connected to the first support arm 21 and the second support arm 22, as well as the connecting arm 23 to form a trapezoidal positioning mounting frame that spans the top of the needle bed base 1. At the same time, since the two mounting end faces of the needle bed base 1 are both standard mounting planes for mounting needle plates, two sets of supporting feet 24 are extended from the inner sides of the first support arm 21 and the second support arm 22, and the supporting end faces of the supporting feet 24 are attached and matched with the two mounting end faces of the needle bed base 1. Through multiple positioning mounting frames arranged at intervals in the length direction of the needle bed base, the mounting guide rail tooling is placed on the two mounting end faces 11 of the needle bed base 1. Through the support of the supporting feet 24, the mounting guide rail tooling and the needle bed base 1 are stably supported and the support positioning on the mounting end faces is achieved.
[0029] In a specific embodiment of the present case, the connecting portion includes a first connecting rod 31 sequentially connecting multiple connecting arms 23, a second connecting rod 32 connecting the extended ends of multiple first support arms 21, and a third connecting rod 33 connecting the extended ends of multiple second support arms 22.
[0030] The needle bed base 1 has a first guide rail 101, and the track detection bracket includes a first detection bracket 25 extending from the second connecting rod 32. The first detection bracket 25 has two first mounting seats opposite to the upper end face and outer end face of the first guide rail 101, and the track detection device 27 is arranged on the two first mounting seats.
[0031] The needle bed base has a second guide rail 102, and the track detection bracket includes a second detection bracket 26 extending from the third connecting rod 33. The second detection bracket 26 has two second mounting seats opposite to the upper end face and the outer end face of the second guide rail 102, and the two second mounting seats are both provided with a track detection device 27. Preferably, the track detection device is a micrometer.
[0032] For the double-system knitting machine, the first guide rail 101 and the second guide rail 102 are respectively arranged below the two mounting end surfaces 11 of the needle plate base 1. To facilitate the installation of the two guide rails, track detection devices are arranged at both ends of the first support arm 21 and the second support arm 22 of the positioning mounting frame. Specifically, the positioning mounting frame is formed into a symmetrical structure by the connecting arm 23, the first support arm 21 and the second support arm 22, and the arrangement structure of the first support arm 21 and the second support arm 22 is the same.
[0033] Specifically, multiple positioning mounting frames are connected by a first connecting rod 31, and the first connecting rod 31 connects the connecting arms of multiple positioning mounting frames. Multiple positioning mounting frames are connected as one from the top. A second connecting rod 32 and a third connecting rod 33 are respectively arranged at the lower extending ends of the first support arm 21 and the second support arm 22, and the second connecting rod 32 and the third connecting rod 33 are both extended along the length direction of the needle bed base 1. The track detection device 27 can be distributed in multiple length directions of the second connecting rod 32 and the third connecting rod 33.

The guide rail is installed on the needle bed base 1 through both ends, and a support step with a support interface of a rectangular guide rail is arranged on the needle bed base 1. During the processing, the support step is reserved with an installation gap, and the installation position of the guide rail is raised by installing a pressure plate. By setting multiple track detection devices, the installation accuracy of the guide rail can be accurately detected and adjusted by sight.
[0034] The first detection bracket 25 and the second detection bracket 26 are both L-shaped brackets, which are respectively mounted on the second connecting rod 32 and the third connecting rod 33, and the horizontal part and the vertical part of the L-shaped bracket are used to form two mounting seats for mounting the track detection device 27. Specifically, the first detection bracket 25 is opposite to the first guide rail 101, and the second detection bracket 26 is opposite to the second guide rail 102. It should be noted that after the guide rails are installed on the needle bed base 1, the two guide rails on both sides are arranged perpendicular to the needle bed mounting end face on the same side, and the side of the guide rail perpendicular to the mounting end face is set as the upper end face, and the side of the guide rail parallel to the mounting end face is set as the outer end face.
[0035] The first detection bracket 25 and the second detection bracket 26 each include a plurality of brackets distributed along the length direction of the connection portion.
[0036] The track detection device 27 uses a micrometer, which is arranged corresponding to the upper end face and the outer end face respectively, and is distributed in multiple numbers along the length direction of the needle bed base 1, so that the two ends of the guide rail in the length direction can be adjusted through multi-point detection to ensure the installation straightness of the guide rail.
