Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0026] like Figures 1-6 As shown, this utility model embodiment specifically provides a 72V single-lithium battery rail cutting machine, including:

[0027] A 72V lithium battery pack 1 is detachably and lockably mounted on a mounting base 3 on top of the motor 2; used to provide power to the motor 2.

[0028] Power adapter socket 4 is installed on one side of motor 2; by connecting the adapter plug of the external power cord to power adapter socket 4, working power can be provided to motor 2. This setting can reduce the weight of the hand when the operator removes the 72V lithium battery pack 1, and can also run the cutting machine as a backup.

[0029] The connecting plate 5 is mounted on one end to the motor 2 and on the other end to a rotatable cutter head 6. The motor 2 and cutter head 6 are connected via a transmission mechanism 7. The connecting plate 5 includes a main connecting plate 51 and a secondary connecting plate 52, which are detachably and lockably connected. By adjusting the distance between the main connecting plate 51 and the secondary connecting plate 52, the length between the driving pulley and the driven pulley is made less than the length of the transmission belt. This allows for easier installation by assembly or maintenance personnel when splicing the transmission belt, saving time and effort.

[0030] The main connecting plate 51 also includes: a first waist-shaped slot 53 and a second waist-shaped slot 54. The first waist-shaped slot 53 and the second waist-shaped slot 54 are linearly spaced at one end of the main connecting plate 51, and the second waist-shaped slot 54 is locked and fixed to the secondary connecting plate 52 by locking bolts, so as to achieve the purpose of quickly adjusting and locking the distance between the secondary connecting plate 52 and the main connecting plate 51.

[0031] The main connecting plate 51 also includes: a through groove 55 and a fixing sleeve 56; the through groove 55 is opened on the main connecting plate 51 between the first waist-shaped slot hole 53 and the second waist-shaped slot hole 54, and the fixing sleeve 56 is movably inserted into the through groove 55. The locking block of the fixing sleeve 56 is locked and fixed to the first waist-shaped slot hole 53 by locking bolts.

[0032] It also includes a fixed swing frame 8, one end of which is fixed and locked to the rail, and the other end is equipped with a plug shaft 81. The plug shaft 81 is inserted into the fixed sleeve 56 so that when the operator holds the cutting machine to perform cutting operations, the cutting machine can swing to cut the rail.

[0033] It also includes a positioning mechanism 9, which includes: a fixing block 91, a positioning rod 92, a spring 93, a limiting block 94, and an abutment block 95. The fixing block 91 is installed on the secondary connecting plate 52. The positioning rod 92 is slidably inserted into the fixing block 91. The spring 93 is sleeved on the positioning rod 92. One end of the spring 93 abuts against the limiting block 94, and the other end abuts against the U-shaped groove wall of the fixing block 91. The limiting block 94 is fixedly sleeved on the positioning rod 92. The abutment block 95 is set at one end of the main connecting plate 51 and is used to abut against the end of the positioning rod 92 for positioning. With the aforementioned positioning mechanism 9, when the transmission belt is installed, the positioning rod 92 on the secondary connecting plate 52 moves closer to the abutment block 95, and its spring 93 is compressed. At this time, the length of the transmission belt is greater than the distance between the driven pulley and the driving pulley, making it easier to install the transmission belt. After installation, the tension of the transmission belt needs to be adjusted. By moving the secondary connecting plate 52 away from the main connecting plate 51, the compressed spring 93 gradually returns to its free state, and the end of the positioning rod 92 still abuts against the abutment block 95, but the spring 93 is not compressed. At this time, the main connecting plate 51 and the secondary connecting plate 52 can be tightened and locked with locking bolts to achieve the purpose of positioning indication of the locking position of the main connecting plate 51 and the secondary connecting plate 52. Furthermore, after locking the main connecting plate 51 and the secondary connecting plate 52, the aforementioned fixing sleeve 56 can be locked and fixed to the main connecting plate 51, and the outer wall of the fixing sleeve 56 abuts and clamps against the end face of the secondary connecting plate 52, further enhancing the overall stability of the connecting plate 5 structure.

[0034] It also includes a main protective shell 57 and a secondary protective shell 58, which are detachably locked to the main connecting plate 51 and the secondary connecting plate 52 by locking screws, so as to cover and protect the transmission mechanism 7 and avoid external interference.

[0035] The transmission mechanism 7 includes a driving pulley, a driven pulley, and a transmission belt. The driving pulley is connected to the output end of the motor 2, the driven pulley is connected to the shaft end of the cutter head 6, and the driving pulley and the driven pulley are connected by the transmission belt.

[0036] The end face of the auxiliary connecting plate 52 is an arc-shaped surface, which is used to fit and abut against the outer wall of the fixed sleeve 56 for better limiting, clamping and fixing.

[0037] It also includes a main handle 10 and a secondary handle 11, which are respectively installed on the motor 2 for easy hand-held use by operators.

[0038] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
