[0024] Next, specifically describe the specific settings and functions of its adjusting device 5 and dust collection device 6.

[0025] In this implementation: The adjusting device 5 includes a motor 1 51. A cavity 52 is opened inside the base 1. The motor 1 51 is fixedly installed on the surface of the cavity 52. The output end of the motor 1 51 is fixedly connected to a driving bevel gear 53. The surface of the driving bevel gear 53 is meshed with a driven bevel gear 54. The surface of the driven bevel gear 54 is fixedly connected to a bi-directional threaded rod 55. The bi-directional threaded rod 55 penetrates and is rotatably connected to the surface of the base 1. The bi-directional threaded rod 55 is threadedly connected to the inner walls of the driving seat 2 and the tailstock 3.

[0026] The effects achieved by the above components are: When machining workpieces of different sizes is required, the motor 1 51 can be started to make the driving bevel gear 53 rotate, and then the driven bevel gear 54 drives the bi-directional threaded rod 55 to rotate, so that the driving seat 2 and the tailstock 3 move towards or away from each other, thereby adjusting the distance between the two to adapt to workpieces of different sizes.

[0027] Specifically, a guide rod 56 is fixedly connected to the surface of the base 1. Anti-disengagement discs 57 are fixedly connected to both ends of the bi-directional threaded rod 55 and the guide rod 56.

[0028] The effects achieved by the above components are: The set guide rod 56 enables the driving seat 2 and the tailstock 3 to move horizontally smoothly. The set anti-disengagement discs 57 ensure that the driving seat 2 and the tailstock 3 do not disengage from the base 1.

[0029] Specifically, anti-disengagement grooves 58 are opened inside both the driving seat 2 and the tailstock 3. The number of anti-disengagement grooves 58 is two groups and they are symmetrically arranged. The bi-directional threaded rod 55 and the guide rod 56 are both arranged inside the anti-disengagement grooves 58.

[0030] The effects achieved by the above components are as follows: The anti - detachment groove 58 is provided to place both the bidirectional threaded rod 55 and the guide rod 56, and also to cooperate with the anti - detachment disc 57 to ensure that the driving seat 2 and the tailstock 3 do not separate from the base 1.

[0031] Specifically, two groups of anti - detachment discs 57 are respectively slidably connected to the surface of a group of anti - detachment grooves 58, and heat dissipation grooves 59 are formed on the bottom surface of the base 1 near the first motor 51.

[0032] The effects achieved by the above components are as follows: The heat dissipation grooves 59 are provided to facilitate the heat dissipation of the first motor 51.

[0033] Specifically, a dust collection device 6 is provided on the surface of the base 1. The dust collection device 6 includes a dust collection plate 61, and the dust collection plate 61 is fixedly connected to the surface of the base 1. The number of the dust collection plates 61 is two groups and they are symmetrically arranged. Placement grooves 62 are formed on the surfaces of the driving seat 2 and the tailstock 3, and the dust collection plate 61 is slidably connected to the surface of the placement groove 62.

[0034] The effects achieved by the above components are as follows: When the adjustment is made so that the driving seat 2 and the tailstock 3 move away from each other, the dust collection plate 61 will also slide out of the placement groove 62, and the dust and debris generated during processing will fall into the dust collection plate 61. The placement groove 62 is provided to facilitate the placement of the dust collection plate 61.

[0035] Specifically, motors two 63 are fixedly installed on the surfaces of the placement grooves 62. The output ends of the motors two 63 are fixedly connected with screw rods 64, and the screw rods 64 are rotatably connected to the surfaces of the placement grooves 62. A movable plate 65 is threadedly connected to the surface of the screw rod 64, and the movable plate 65 is slidably connected to the surface of the placement groove 62.

[0036] The effects achieved by the above components are as follows: When the driving seat 2 and the tailstock 3 move towards each other and close to the base 1, the motor two 63 can be started to rotate the screw rod 64, and then the movable plate 65 slides along the placement groove 62.

[0037] Specifically, a spring 66 is fixedly connected to the inner wall of the movable plate 65, and the other end of the spring 66 is fixedly connected with a cleaning brush 67.

[0038] The effects achieved by the above components are as follows: The sliding of the movable plate 65 causes the cleaning brush 67 to sweep the dust and debris collected on the dust collection plate 61 into the dust collection groove 68 and fall into the dust collection box 69. The dust collection box 69 can be regularly disassembled for replacement or cleaning. The spring 66 provided makes the cleaning brush 67 always closely adhere to the dust collection plate 61 during the sliding process to avoid the situation of incomplete cleaning.

[0039] Working principle: By setting the adjusting device 5, when machining workpieces of different sizes is required, the first motor 51 can be started to make the driving bevel gear 53 rotate, and then the driven bevel gear 54 drives the bidirectional threaded rod 55 to rotate, causing the driving seat 2 and the tailstock 3 to move towards or away from each other, thereby adjusting the distance between them to adapt to workpieces of different sizes. Subsequently, turntables 4 of corresponding sizes are installed on the driving seat 2 and the tailstock 3, and finally the workpiece is clamped on the turntable 4 for machining. The guiding rods 56 provided enable the driving seat 2 and the tailstock 3 to move horizontally smoothly. The anti-disengagement disks 57 and anti-disengagement grooves 58 ensure that the driving seat 2 and the tailstock 3 do not disengage from the base 1. By setting the adjusting device 5, the distance between the driving seat 2 and the tailstock 3 can be adjusted to adapt to the machining of workpieces of different sizes, avoiding the situation where the workpiece is too large to be placed on the turntable 4, thus effectively improving the applicability of the equipment. Additionally, by setting the dust collection device 6, when the adjusting makes the driving seat 2 and the tailstock 3 move away from each other, the dust collection plate 61 will also slide out of the placement groove 62, and the dust and debris generated during machining will fall into the dust collection plate 61. When the driving seat 2 and the tailstock 3 move towards each other and close with the base 1, the second motor 63 can be started to make the screw rod 64 rotate, and then the movable plate 65 slides along the placement groove 62, and at the same time, the cleaning brush 67 sweeps the dust and debris collected on the dust collection plate 61 into the dust collection groove 68 and falls into the dust collection box 69. The dust collection box 69 can be regularly disassembled for replacement or cleaning. The springs 66 provided enable the cleaning brush 67 to always closely adhere to the dust collection plate 61 during the sliding process, avoiding the situation of unclean cleaning. By setting the dust collection device 6, it can prevent dust and debris from falling between the driving seat 2, the tailstock 3 and the base 1, resulting in affecting the subsequent adjustment of the equipment, and is convenient for collection and cleaning, thus effectively improving the convenience of the equipment.
