[0003] The existing processing method of the above-mentioned pulley is to first produce the wheel body 6 by die-casting, and then use the above-mentioned cutting tool 8 to cut and shape the annular groove 7 on the side wall of the wheel body 6, thereby realizing the molding of the pulley.

[0004] However, in actual use, when the above-mentioned cutting tool is used to cut the side wall of the wheel body 6, since the cutter head on the cutting tool 8 can only process one circle of annular groove 7 at a time, in order to form a pulley with multiple sets of annular grooves 7, it is necessary to repeatedly use the above-mentioned cutting tool 8 to process the annular grooves 7 on the side wall of the wheel body 6 one by one. The overall processing efficiency is low, which is not conducive to use. Utility Model Content

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0036] An embodiment of the present application discloses a tool for machining a fitness pulley.

[0037] Example 1:

[0038] Reference Figure 2 A tool for processing a fitness pulley includes a horizontally placed blade body 1. In this embodiment, the left end of the blade body 1 is bent upward, and a blade head 2 is integrally formed on the left end of the blade body 1. The blade heads 2 are provided in several groups, and the groups of blade heads 2 are evenly spaced along the width direction of the blade body 1.

[0039] Reference Figure 2 When in use, the left end of the blade body 1 is bent so that after the blade body 1 is installed horizontally, the end with the cutter head 2 can be set at an angle, so that it is easier to cut the side wall of the pulley through the cutter head 2. The setting of several groups of cutter heads 2 realizes that during the processing of the pulley, several groups of annular grooves 7 on the side of the pulley can be processed and formed at one time, thereby improving the processing efficiency of the pulley and making it more convenient to use.

[0040] Example 2:

[0041] Reference Figure 3 and Figure 4The difference between this embodiment and embodiment 1 is that a clamping structure 3 is provided at the left end of the blade body 1, and several groups of blade heads 2 are installed on the blade body 1 through the clamping structure 3, that is, a plug-in block 21 is integrally formed at the end of the blade head 2 away from the blade, and the plug-in block 21 is arranged as a whole at an angle, and the inclination direction of the plug-in block 21 is the same as the bending direction of the left end of the blade body 1. A plug-in groove 11 is opened at the left end of the blade body 1 along the length direction of the blade body 1, and the plug-in block 21 is embedded in the plug-in groove 11. The clamping structure 3 is used to synchronously clamp several plug-in blocks 21 in the plug-in groove 11, thereby realizing the detachable connection of the blade head 2.

[0042] Reference Figure 3 and Figure 4 The clamping structure 3 is composed of a first positioning bolt 31 and a first locking nut 32. The first locking nut 32 is threadedly matched with the end portion of the first positioning bolt 31. The first positioning bolt 31 is arranged on the blade body 1 along the width direction of the blade body 1, and a first through hole is correspondingly opened on the plug-in block 21; when in use, first insert the plug-in block 21 into the plug-in slot 11, and insert several groups of cutter heads 2 into the corresponding plug-in slots 11 one by one, and then pass one end of the first positioning bolt 31 through the blade body 1 and the first through hole in turn and then out of the blade body 1, and then screw the first locking nut 32 so that the side wall of the first locking nut 32 abuts against the side wall of the blade body 1, thereby fixing the cutter head 2.

[0043] The implementation principle of the embodiment of the present application is: when in use, the staff inserts the cutter heads 2 into the plug-in slots 11 one by one, and fixes the cutter heads 2 on the blade body 1 through the first positioning bolt 31, and then fixes them through the first locking nut 32 to complete the overall assembly of the cutter head 2. When the cutter head 2 needs to be replaced, it is only necessary to remove the first locking nut 32 and the first positioning bolt 31 to disassemble the cutter head 2; in addition, when installing the cutter head 2, the staff can also choose to insert a number of cutter heads 2 that is less than the number of plug-in slots 11 as needed, and change the insertion position of the cutter head 2 to adjust the distance between two adjacent cutter heads 2, so as to be suitable for processing pulleys of different models.

[0044] Example 3:

[0045] Reference Figure 5 and Figure 6The difference between this embodiment and embodiment 2 is that, in this embodiment, a T-shaped sliding block 22 is integrally formed at the end of the cutter head 2 away from the blade, a sliding groove 12 is provided at the left end of the blade body 1, and the sliding groove 12 is opened along the width direction of the blade body 1, and a sliding fit is formed between the sliding block 22 and the sliding groove 12. When in use, the sliding groove 12 limits the sliding block 22 to prevent the sliding block 22 from escaping from the sliding groove 12 along the length direction of the blade body 1, and then the clamping structure 3 is used to prevent the sliding block 22 from escaping from the sliding groove 12 along the width direction of the blade body 1. Through the cooperation of the two, the cutter head 2 can be installed on the blade body 1.

[0046] Reference Figure 5 and Figure 6 In this embodiment, the clamping structure 3 is composed of a blocking plate 33, a second positioning bolt 34, a gasket 36 and a second locking nut 35, wherein the blocking plate 33 is fixed to the blade body 1 by bolts, and the blocking plate 33 blocks one end opening of the sliding groove 12, and one end of the second positioning bolt 34 passes through the blocking plate 33 and the sliding groove 12 and is located on the outside of the blade body 1, and the second locking nut 35 is threadedly connected to the end of the second positioning bolt 34, and the second locking nut 35 is in abutment with the side wall of the blade body 1. At the same time, a second through hole is opened on the sliding block 22, and the second through hole and the second positioning bolt 34 form an interlaced fit.

[0047] Reference Figure 5 and Figure 6 When in use, first unscrew the second locking nut 35 from the second positioning bolt 34, and remove the gasket 36, then align the second through hole on the sliding block 22 with the second positioning bolt 34, and pass several groups of cutter heads 2 through the sliding block 22 on the second positioning bolt 34, and at the same time make the sliding block 22 slide in the sliding groove 12. When several groups of cutter heads 2 are slidingly arranged in the sliding groove 12, and the side wall of the last group of cutter heads 2 is flush with the side wall of the blade body 1, the gasket 36 can be passed through the second positioning bolt 34 again, and the second locking nut 35 can be screwed on the second positioning bolt 34 to complete the assembly of the cutter head 2.

[0048] Reference Figure 5 and Figure 6 In addition, an adjusting pad 4 is provided between two adjacent groups of cutter heads 2. The end of the adjusting pad 4 is also slidably set in the sliding groove 12. A third through hole is opened on the adjusting pad 4, and the third through hole is also inserted and matched with the second positioning bolt 34. When in use, one end of the second positioning bolt 34 is passed through the blocking plate 33, the cutter head 2 and the adjusting pad 4, and then locked by the second locking nut 35 and the gasket 36. In this process, the distance between the two adjacent cutter heads 2 can be adjusted by increasing the number of adjusting pads 4, so that the overall tool is suitable for the processing needs of different types of pulleys.

[0049] Reference Figure 5 and Figure 6 At the same time, in order to facilitate the staff to control the distance between the two blade heads 2, a scale line 5 is formed on the blade body 1 along the width direction of the blade body 1. The scale line 5 is located at one end of the blade body 1 close to the sliding groove 12.

[0050] The implementation principle of the embodiment of the present application is: when in use, the staff first fixes the sealing plate 33 on the blade body 1, and then slides several groups of cutter heads 2 and several adjustment pads 4 into the sliding groove 12 one by one in sequence as needed to adjust the distance between two adjacent cutter heads 2. After all adjustments are completed, the gasket 36 and the second locking nut 35 can be reconnected to the second positioning bolt 34 to complete the assembly of the cutter head 2; when it is necessary to adjust the installation distance between two adjacent cutter heads 2, the staff only needs to adjust the setting number of the adjustment gasket 36, so that the tool as a whole is suitable for processing different types of pulleys.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
