DETAILED DESCRIPTION

[0018] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] like Figure 1-4As shown, the utility model is a workpiece fixing device for deep hole processing on a lathe, comprising a working box 1, an adjusting box 2 is provided at the bottom of the working box 1, a motor 21 is fixedly installed on the side of the adjusting box 2, a screw rod 22 is provided at the output end of the motor 21, a first slider 23 is threadedly connected to the screw rod 22, a limit seat 3 is provided on the top of the first slider 23, by turning on the motor 21 switch, the screw rod 22 at the output end of the motor 21 starts to rotate in the adjusting box 2 through the bearing, and the first slider 23 threadedly connected to the screw rod 2 starts to move, and a groove is provided on the adjusting box 2 to limit the rotation of the first slider 23, so as to ensure that the first slider 23 moves left and right on the adjusting box 2, and then the limit seat 23 on one side can be moved, so as to clamp and fix shafts of different lengths.

[0020] A first cylinder 31 is provided on the top of the limiting seat 3, and a holder 33 is provided at the output end of the first cylinder 31. A block 34 is movably provided in the holder 33. In the limiting seat 3, blocks 34 and holders 33 are provided at the bottom and the top. The holder 33 at the bottom is fixedly installed with the limiting seat 3, and the holder 33 at the top is fixedly connected with the output end of the first cylinder 31. When the switch of the first cylinder 31 is turned on, the output end of the first cylinder 31 pushes the holder 33 forward, and the block 34 at the bottom of the holder 33 is engaged and limited with the processing shaft, which can limit and fix shafts of different diameters, ensuring that the shaft will not shake during the deep hole processing, thereby ensuring the deep hole processing effect.

[0021] The second sliders 41 are symmetrically and movably provided on both sides of the bottom of the clamping block 34, and the rigid spring 42 is fixedly connected below the second slider 41. When the clamping blocks 34 at the upper and lower positions clamp and limit the shaft, the clamping block 34 starts to move into the clamping seat 33, and the second slider 41 starts to move outward, deforming the rigid spring 4 outward, so that the second slider 41 can support the clamping block above, and the contact surface between the clamping block 34 and the shaft can be in an adaptive clamping force, so as to avoid the first cylinder 31 from exerting too much force when clamping the shaft and causing hard pressure damage to the surface of the shaft, thereby protecting the surface of the shaft.

[0022] A dust box 6 is provided on the top of the working box 1, and an air pipe 62 is provided at the air inlet end of the dust box 6. An air inlet 61 is provided at the end of the air pipe 62. When processing the shaft, by turning on the vacuum pump switch inside the dust box 6, suction can be generated at the air inlet 61, so that waste chips generated during the processing can be adsorbed, and the filter net in the dust box can be filtered and collected in a centralized manner to prevent waste chips from polluting the working environment.

[0023] In the above solution, the bottom of the working box 1 is provided with supporting legs 11 for supporting.

[0024] In the above scheme, the working box 1 is movably provided with a cabinet door 12 on the side, and the cabinet door 12 is provided with a handle 13. The cabinet door 12 is opened by the handle 13 to perform deep hole processing on the shaft.

[0025] In the above scheme, a limit seat 3 is fixedly installed on the top of the adjustment box 2, and another limit seat 3 is slidably connected to the adjustment box 2 through a first slider 23. One end of the shaft is engaged in the fixed limit seat 3, and the other end is adjusted by the movable limit seat 3 to clamp and fix shafts of different lengths.

[0026] In the above scheme, the top seat 33 is fixedly connected to the guide rod 32, and the guide rod 32 is movably connected to the limit seat 3. When the first cylinder 31 pushes the seat 3, the guide rod 32 can guide the movement of the top seat 3.

[0027] In the above scheme, a slide groove 36 is provided in the base 33, and the slide groove 36 is slidably connected to the guide block 35. The guide block 35 is fixedly connected to the side of the block 34. When the block 34 moves inward in the base 33, the guide block 35 can limit and guide the movement of the block 34 to ensure the smooth movement of the block 34.

[0028] In the above scheme, the second cylinder 5 is fixedly installed on the side wall of the working box 1, and a deep hole machine 51 is provided at the output end of the second cylinder 5. The bottom of the deep hole machine 51 is slidably connected to the slide rail 52. By turning on the switch of the second cylinder 5, the second cylinder 5 pushes the deep hole machine 51 to slide on the slide rail 52. Turning on the switch of the deep hole machine 51 can enable its output end to perform deep hole processing on the shaft.

[0029] Working principle:

[0030] When the workpiece fixing device for deep hole processing of a lathe is in operation, the cabinet door 12 of the work box 1 is opened, and the clamping position of the shaft is adjusted by turning on the motor 21 switch, and the shaft is placed in the clamping block 34. The shaft can be stably clamped by the first cylinder 31, and deep hole processing can be stably performed on the shaft by turning on the second cylinder 5 and the deep hole machine 51 switch.
