Description

Technical Field

[0001] The utility model relates to the technical field of lead screw processing, in particular to a positioning and supporting device for long lead screw processing. Background Technique

[0002] The ball screw is an ideal product for converting rotary motion into linear motion or vice versa. The ball screw is the most commonly used transmission element in machine tools and precision machinery. Its main function is to convert rotary motion into linear motion or convert torque into axial reciprocating force, and at the same time has the characteristics of high precision, reversibility and high efficiency. Due to its very small frictional resistance, the ball screw is widely used in various industrial equipment and precision instruments.

[0003] The utility model with the application number CN202022999687.8 discloses a support device for lead screw processing. The lead screw is clamped and fixed by four rollers, and the fixing effect is better. Through the screw rod and the cross bar, the top roller can be lifted, so that lead screws of various different sizes can be fixed.

[0004] The above device clamps and fixes the lead screw through four rollers. The distance between the upper and lower rollers is fixed and cannot be adjusted. It is inconvenient to clamp and fix the lead screw with a relatively large diameter. The lead screw is easy to fall off, reducing the processing accuracy. It is not convenient to collect the waste cut during turning and clean the waste, reducing the work efficiency.

[0005] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

[0006] The purpose of the utility model is to solve the above problems and design a positioning and supporting device for long lead screw processing.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A positioning and supporting device for long lead screw processing includes a lathe main body. A sliding base is slidably connected to the lathe main body. A guiding chute is provided on the sliding base. Two sliding bottom plates are slidably connected in the guiding chute. Fixed brackets are installed on both sides of the sliding base. A lower rotating rod is rotatably connected between the fixed brackets. An L-shaped fixed frame is installed on the sliding base. A power push rod is installed on the L-shaped fixed frame. A U-shaped fixing plate is installed on the telescopic end of the power push rod. A fixed frame is installed at the bottom end of the U-shaped fixing plate. Guiding through grooves are provided on both sides of the fixed frame. Two moving sliders are slidably connected in the guiding through grooves. An upper rotating rod is rotatably connected between the moving sliders.

[0009] Further, a fixed sleeve is installed on the side of the fixed bracket away from the lower rotating rod. A lifting slide rod is slidably connected inside the fixed sleeve. One end of the moving slider away from the upper rotating rod extends out of the guiding through groove, and the top end of the lifting slide rod is fixedly connected to the moving slider.

[0010] Further, a bearing plate is installed on the fixed bracket. The bearing plate is located below the lower rotating rod. An active magnetic attraction plate is provided on the bearing plate, and the active magnetic attraction plate is located directly below the rotating rod.

[0011] Further, a bidirectional threaded lead screw is rotatably connected inside the guiding chute. Two threaded grooves with opposite spiral directions are provided on the bidirectional threaded lead screw. The two sliding bottom plates are respectively threadedly connected to the two threaded grooves. One end of the bidirectional threaded lead screw penetrates and extends out of the guiding chute, and a rotating handle is installed at one end of the bidirectional threaded lead screw.

[0012] Further, there are two lower rotating rods and two upper rotating rods. The positions of the two lower rotating rods are opposite to those of the two upper rotating rods.

[0013] Further, two active magnetic attraction plates are provided. The two active magnetic attraction plates are respectively located below the two lower rotating rods, and the heights of the two active magnetic attraction plates are different.

[0014] Compared with the prior art, the technical solution has the following beneficial effects:

[0015] By driving the fixed bracket and the lower rotating rod to move through the sliding bottom plate, the distance between the two lower rotating rods can be adjusted, which is applicable to lead screws of different diameter sizes. By driving the U-shaped fixing plate and the fixed frame to descend through the power push rod, the fixed frame drives the two upper rotating rods to descend, so that the upper rotating rods press on the upper side of the lead screw. The lead screw is clamped and fixed by the upper rotating rod and the lower rotating rod, and the fixing effect is good. Lead screws of different diameter sizes can be fixed, improving the processing efficiency;

[0016] When adjusting the distance between the two lower rotating rods through the fixed sleeve and the lifting slide rod, the two upper rotating rods can be driven to move simultaneously, and the distance between the two upper rotating rods can be adjusted simultaneously. When the upper rotating rod ascends and descends, the lifting slide rod ascends and descends along the fixed sleeve, which will not prevent the fixed frame from ascending and descending, facilitating adjustment;

[0017] The waste can be magnetically attracted and fixed through the active magnetic attraction plate. The active magnetic attraction plate is convenient to remove from the bearing plate, facilitating the cleaning and collection of the waste and improving the cleaning efficiency;

[0018] The heights of the two active magnetic attraction plates are different. When the two lower rotating rods approach each other, one of the two active magnetic attraction plates is in a higher position and the other is in a lower position, and the two active magnetic attraction plates will not collide, preventing the active magnetic attraction plate from falling off the bearing plate.

Guide through slots 11 are provided on both sides of the fixed frame 10. Two moving sliders 12 are slidably connected in the guide through slots 11. An upper rotating rod 13 is rotatably connected between the moving sliders 12.

[0027] When processing the lead screw, the sliding bottom plate 4 can slide along the guiding chute 3. The sliding bottom plate 4 drives the fixed bracket 5 and the lower rotating rod 6 to move, and the distance between the two lower rotating rods 6 can be adjusted, which is suitable for lead screws of different diameters. The power push rod 8 starts to work. The telescopic end of the power push rod 8 extends in to drive the C-shaped fixing plate and the fixed frame 10 to descend. The fixed frame 10 drives the two upper rotating rods 13 to descend, so that the upper rotating rod 13 presses on the upper side of the lead screw. The lead screw is clamped and fixed by the upper rotating rod 13 and the lower rotating rod 6.

One end of the moving slider 12 away from the upper rotating rod 13 extends out of the guide through slot 11. The top end of the lifting slide rod 15 is fixedly connected to the moving slider 12.

[0029] When the sliding bottom plate 4 drives the fixed bracket 5 and the lower rotating rod 6 to move, the fixed bracket 5 drives the moving slider 12 to move along the guide through slot 11 through the fixed sleeve 14 and the lifting slide rod 15. The moving slider 12 drives the upper rotating rod 13 to move. When adjusting the distance between the two lower rotating rods 6, the two upper rotating rods 13 can be driven to move at the same time, and the distance between the two upper rotating rods 13 can be adjusted at the same time. When the upper rotating rod 13 is lifted or lowered, the lifting slide rod 15 lifts or lowers along the fixed sleeve 14, which will not prevent the fixed frame 10 from lifting or lowering, facilitating the adjustment.

The bidirectional threaded screw 18 rotates through two threaded grooves to drive the two sliding base plates 4 to move relatively away or closer. The sliding base plates 4 slide along the guide grooves 3. The guide grooves 3 drive the fixed bracket 5 and the lower rotating rod 6 to move, thereby facilitating the adjustment of the distance between the two lower rotating rods 6.

[0034] Refer to the instruction manual Figure 3 Two movable magnetic suction plates 17 are provided, and the two movable magnetic suction plates 17 are respectively located below the two lower rotating rollers 6, and the heights of the two movable magnetic suction plates 17 are different.

[0035] The two movable magnetic plates 17 have different heights. When the two lower rotating rollers 6 approach each other, one of the two movable magnetic plates 17 is located above and the other is located below. The two movable magnetic plates 17 will not collide, thereby preventing the movable magnetic plates 17 from falling off the supporting plate 16.
