The tool length compensation structure of the horizontal machining center can adjust the distance between the tool head and the connecting block through the setting of the compensation component, so that the tool can be used for workpieces of different depths, solving the problem of high procurement cost and long cycle for customized tools, and different tools need to be replaced for boxes with different hole depths, which brings difficulties to mass production and greatly reduces the processing efficiency.

[0004] The above device adjusts the distance between the cutter head and the connecting head by turning the handle, so that the tool can be used for workpieces of different depths. However, the cutter head will produce slight vibrations when working, causing the handle to rotate when the cutter head is working, causing the cutter head to shake up and down when working and unable to maintain a stable working state. Utility Model Content

[0005] In response to the above problem, a machining center with a tool length compensation structure is provided. By moving the turn block upward, the pull rod and positioning pin at the bottom of the turn block will also move upward, so that the positioning pin is away from the positioning slot on the top of the casing. At this time, the turn block can be rotated to drive the turntable to rotate, and the adjusting screw at the bottom of the turntable will also rotate accordingly, thereby driving the moving block, extension block and cutter head to move, making it convenient to adjust the length of the cutter head to adapt to workpieces of different sizes.

[0006] To solve the problems of the prior art, the utility model provides a machining center with a tool length compensation structure, comprising a casing, an adjusting screw rotatably arranged inside the casing, the end of the adjusting screw rotatably connected to the inner wall of the casing through a bearing, a moving block is connected to the external thread of the adjusting screw, an extension block is arranged at the bottom of the moving block, one end of the extension block extends to the outside of the casing and is provided with a second connecting block, a first connecting block is movably arranged at the bottom of the second connecting block, a tool head for processing is arranged at the bottom of the first connecting block, and the top end of the adjusting screw extends to the outside of the casing and is provided with a positioning component.

[0008] Preferably, a plurality of positioning grooves adapted to the positioning pins are provided in an annular shape on the top of the housing.

[0009] Preferably, a rotating block is provided on the top of the two pull rods.

[0010] Preferably, the moving block is internally movably provided with symmetrical guide rods, and both ends of the guide rods are connected to the inner wall of the casing.

[0011] Preferably, the second connecting block is internally threadedly connected with a fixing bolt, the bottom end of the fixing bolt passes through the first connecting block, the outside of the fixing bolt is also threadedly connected with a fixing nut, and the second connecting block is internally provided with a plurality of threaded holes for installing the fixing bolts.

[0012] Compared with the prior art, the utility model has the following beneficial effects: by moving the rotating block upward, the pull rod and the positioning pin at the bottom of the rotating block will also move upward, so that the positioning pin is away from the positioning groove at the top of the casing. At this time, the rotating block can be rotated to drive the turntable to rotate, and the adjusting screw at the bottom of the turntable will also rotate accordingly, thereby driving the moving block, the extension block and the cutter head to move, making it convenient to adjust the length of the cutter head to adapt to workpieces of different sizes.

[0013] By turning the fixing nut, the fixing nut gradually breaks away from the close contact with the fixing bolt. After ensuring that the two are completely separated, slowly unscrew the fixing bolt. In this way, the cutter head can be easily replaced. After the replacement is completed, the fixing nut is accurately adjusted to make it work with the fixing bolt again, thereby ensuring that the cutter head can maintain a more stable state during the processing process, improving the processing accuracy and efficiency.

DETAILED DESCRIPTION

[0021] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figures 1 to 6 As shown, the utility model provides: a machining center with a tool length compensation structure, including a housing 1, an adjusting screw 5 is rotatably arranged inside the housing 1, the end of the adjusting screw 5 is rotatably connected to the inner wall of the housing 1 through a bearing, the external thread of the adjusting screw 5 is connected to a moving block 4, an extension block 7 is arranged at the bottom of the moving block 4, one end of the extension block 7 extends to the outside of the housing 1 and is provided with a second connecting block 14, a first connecting block 13 is movably arranged at the bottom of the second connecting block 14, a tool head 3 for processing is arranged at the bottom of the first connecting block 13, and the top end of the adjusting screw 5 extends to the outside of the housing 1 and is provided with a positioning component.

[0023] The turntable 2 is driven to rotate by rotating the turn block 8, and the adjusting screw 5 at the bottom of the turntable 2 will also rotate, thereby driving the moving block 4, the extension block 7 and the cutter head 3 to move, so as to facilitate the adjustment of the length of the cutter head 3 to adapt to workpieces of different sizes. Thereafter, the positioning component can be used to prevent the cutter head 3 from shaking when processing the workpiece.

[0024] like Figure 3 As shown, the positioning assembly includes a turntable 2 arranged on the top of the adjusting screw 5, a symmetrical pull rod 9 is movably arranged inside the turntable 2, a positioning pin 10 is arranged at the bottom of the pull rod 9, a reset spring 11 is arranged on the outside of the pull rod 9, one end of the reset spring 11 is connected to the top of the positioning pin 10, and the other end of the reset spring 11 is connected to the bottom of the turntable 2.

[0025] The cooperation between the positioning pin 10 and the positioning groove 12 can effectively ensure that the cutter head 3 maintains extremely high stability during the processing, so that the cutter head 3 will not shake during operation, thereby improving the processing accuracy and efficiency.

[0026] like Figure 3 As shown, a plurality of positioning grooves 12 adapted to the positioning pins 10 are formed in an annular shape on the top of the housing 1 .

[0027] The cutter head 3 can be adjusted to any length by using the annularly distributed positioning grooves 12, and then work in conjunction with the positioning pins 10, so that the cutter head 3 after the adjusted length is more stable during processing.

[0028] like Figure 3 As shown, a rotating block 8 is arranged on the top of the two pull rods 9 .

[0029] By using the rotating block 8, the rotating disk 2 can be driven to rotate smoothly in a very convenient manner, thereby improving the flexibility and efficiency of the operation.

[0030] like Figure 2 and Figure 4 As shown, a symmetrical guide rod 6 is movably provided inside the moving block 4 , and both ends of the guide rod 6 are connected to the inner wall of the housing 1 .

[0031] The guide rod 6 ensures that the moving block 4 remains stable during the movement without any positional deviation, thereby avoiding the uncertainty of the moving block 4 in the movement, so that the moving block 4 can be accurately guided to move along a preset designated direction.

[0032] like Figure 5 and Figure 6As shown, the second connecting block 14 is internally threadedly connected with a fixing bolt 15, the bottom end of the fixing bolt 15 passes through the first connecting block 13, the outside of the fixing bolt 15 is also threadedly connected with a fixing nut 16, and the interior of the second connecting block 14 is provided with a plurality of threaded holes for installing the fixing bolt 15.

[0033] By rotating the fixing nut 16, the fixing nut 16 gradually breaks away from the close contact with the fixing bolt 15, and after ensuring that the two are completely separated, the fixing bolt 15 is slowly screwed down. In this way, the cutter head 3 can be easily replaced. After the replacement is completed, the fixing nut 16 is accurately adjusted to make it work with the fixing bolt 15 again, thereby ensuring that the cutter head 3 can maintain a more stable state during the processing, improving the processing accuracy and efficiency.

[0034] Working principle: when it is necessary to adjust the length of the processing cutter head 3, first pull the rotating block 8 upward, and at the same time, the pull rod 9 and the positioning pin 10 at the bottom of the rotating block 8 will also move upward, so that the positioning pin 10 is away from the positioning slot 12 at the top of the casing 1. At this time, the rotating block 8 can be rotated to drive the turntable 2 to rotate, and at the same time, the adjusting screw 5 at the bottom of the turntable 2 will also rotate accordingly, thereby driving the moving block 4, the extension block 7 and the cutter head 3 to move, so as to facilitate the adjustment of the length of the cutter head 3 to adapt to workpieces of different sizes. Afterwards, the positioning pin 10 is used in conjunction with the positioning slot 12 to make the cutter head 3 more stable during processing and no shaking occurs. When the cutter head 3 needs to be replaced, the fixing nut 16 is rotated to make the fixing nut 16 disengage from the contact with the fixing bolt 15. At this time, the fixing bolt 15 is unscrewed, and the cutter head 3 can be replaced. Afterwards, the fixing nut 16 is used in conjunction with the fixing nut 16 to make the cutter head 3 more stable during processing.
