Description

Technical Field

[0001] This utility model relates to the field of straightening machine technology, specifically to a lead screw straightening machine. Background Technology

[0002] A straightening machine is a device designed to detect and straighten bending deformation in shaft-type products after heat treatment. Current automatic straightening machines are high-tech products integrating mechanical, electrical, hydraulic, pneumatic, and computer-aided measurement and analysis. Straightening machines possess excellent technical performance, characterized by high measurement accuracy, fast production cycle, and strong adaptability to ball screw pairs. They can accurately measure the radial runout of circular cross-sections, D-sections, and pitch circles of gears or splines in shaft-type ball screw pairs.

[0003] When straightening a lead screw, it needs to be rotated to perform the inspection. Since the lead screw is not straight, the positions of its two ends are not fixed. Therefore, clamping devices are rarely used to clamp the two ends. Instead, the top roller is used to drive the screw to rotate by friction. However, since the length of the lead screw is not fixed, it takes a long time to align the drive roller with the positions of the two ends of the lead screw for lead screws of different lengths, thus reducing the efficiency of the straightening process.

[0004] Therefore, a lead screw straightening machine is proposed. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a lead screw straightening machine.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A lead screw straightening machine includes a base plate, a mounting frame at the top of the base plate, a lead screw to be straightened within the mounting frame, a support component, a detection component, and a hydraulic straightening component for straightening the lead screw on the base plate, a controller on one side of the mounting frame, a drive component for synchronously rotating both ends of the lead screw within the mounting frame, the drive component including a second motor and a drive roller, a position adjustment component for adjusting the positions of both ends of the lead screw within the mounting frame, the position adjustment component including a slide rail and two first connecting plates slidably mounted thereon, a second connecting plate at the bottom of the first connecting plate, a first electric telescopic rod on one side of the second connecting plate, a limit plate connected to the telescopic end of the first electric telescopic rod, a pressure sensor on the limit plate, and a second electric telescopic rod at the top of the inner side of the mounting frame, the slide rail being connected to the telescopic end of the second electric telescopic rod.

[0008] Furthermore, a first motor is provided on one side of the slide rail, and a bidirectional lead screw is rotatably provided inside the slide rail. The bidirectional lead screw is connected to the main shaft end of the first motor, and two sliders are threaded onto the bidirectional lead screw. The two first connecting plates are respectively connected to one of the sliders.

[0009] Furthermore, the sliders are slidably disposed inside the slide rail, and the two sliders are mirror-symmetrical about the central axis of the bidirectional lead screw.

[0010] Furthermore, both the first connecting plate and the second connecting plate are inverted L-shaped designs, the second motor is located on one side of the first connecting plate, and the drive roller is connected to the main shaft end of the second motor.

[0011] Furthermore, the outer periphery of the drive roller is made of wear-resistant rubber.

[0012] Furthermore, the two second connecting plates are slidably disposed on one side inside the mounting frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention enables the straightening screw to be centered by setting a position adjustment component. At the same time, it ensures that after the positioning is completed, the drive roller automatically aligns with the two ends of the straightening screw, thus eliminating the need for time-consuming adjustment and improving the straightening process efficiency.

[0024] like Figure 1-4As shown, a lead screw straightening machine includes a base plate 1, a mounting frame 2 at the top of the base plate 1, a lead screw 6 to be straightened within the mounting frame 2, a support component 4, a detection component 5, and a hydraulic straightening component 7 for straightening the lead screw 6 on the base plate 1, a controller 3 on one side of the mounting frame 2, and a drive component 9 within the mounting frame 2 for synchronously rotating both ends of the lead screw 6. The drive component 9 includes a second motor 901 and a drive roller 902. A position adjustment component 8 within the mounting frame 2 for adjusting the position of both ends of the lead screw 6 includes a slide rail 801 and two first connecting plates 80 slidably mounted thereon. 5. A second connecting plate 806 is provided at the bottom of the first connecting plate 805. A first electric telescopic rod 807 is provided on one side of the second connecting plate 806. The telescopic end of the first electric telescopic rod 807 is connected to a limit plate 808. A pressure sensor 809 is provided on the limit plate 808. A second electric telescopic rod 10 is provided at the top inside the mounting frame 2. The slide rail 801 is connected to the telescopic end of the second electric telescopic rod 10. Specifically, the supporting component 4, the detection component 5, and the hydraulic straightening component 7 are necessary components of the straightening machine. The straightening machine is existing technology, so the necessary components such as the supporting component 4, the detection component 5, and the hydraulic straightening component 7 will not be described in detail.

[0025] like Figure 3 As shown, a first motor 802 is provided on one side of the slide rail 801. A bidirectional lead screw 803 is rotatably installed inside the slide rail 801. The bidirectional lead screw 803 is connected to the main shaft end of the first motor 802. Two sliders 804 are threaded onto the bidirectional lead screw 803. Two first connecting plates 805 are respectively connected to one of the sliders 804. Specifically, the first motor 802 drives the bidirectional lead screw 803 to rotate, thereby causing the two sliders 804 to move closer or further apart. This, in turn, causes the two limiting plates 808 to move closer or further apart, thus centering the lead screw 6 to be straightened. The pressure sensor 809 can detect the compression pressure during positioning. When the detected pressure value reaches the set value, it will control the first motor 802 to stop working. The pressure sensor 809 is existing technology, so its principle, structure and model will not be described in detail here.

[0026] like Figure 3 As shown, the slider 804 is slidably disposed inside the slide rail 801, and the two sliders 804 are mirror-symmetrical about the central axis of the bidirectional lead screw 803.

[0027] like Figure 3As shown, both the first connecting plate 805 and the second connecting plate 806 are inverted L-shaped designs. The second motor 901 is located on one side of the first connecting plate 805, and the drive roller 902 is connected to the main shaft end of the second motor 901. Specifically, since both the drive roller 902 and the limiting plate 808 slide along with the slider 804, after the lead screw 6 to be straightened is centered and positioned, the drive roller 902 is located directly above both ends of the lead screw 6 to be straightened. When it is driven to rotate, the first electric telescopic rod 807 retracts, causing the two limiting plates 808 to move away from each other, thus preventing friction between the two ends of the lead screw 6 and the limiting plates 808 when it is driven to rotate.

[0028] like Figure 3 and 4 As shown, the outer periphery of the drive roller 902 is made of wear-resistant rubber. Specifically, because the rubber material has a high coefficient of friction and will not deform significantly when squeezed, and its surface is relatively soft, it will not be rigidly squeezed with the lead screw 6 to be straightened, thus avoiding damage to it.

[0029] like Figure 2 As shown, the two second connecting plates 806 are slidably disposed inside one side of the mounting frame 2; specifically, the second connecting plates 806 are slidably disposed inside the mounting frame 2, thus improving their sliding stability.

[0030] In summary: the straight lead screw 6 to be calibrated is placed on the support member 4, and then the position adjustment member 8 enables the straight lead screw 6 to be centered. After positioning, the second electric telescopic rod 10 extends, which enables the drive roller 902 to squeeze the upper part of the straight lead screw 6 to be calibrated. Under the action of the drive member 9, the straight lead screw 6 to be calibrated can be rotated. With the cooperation of the detection member 5 and the straight lead screw 6 to be calibrated, it can be calibrated.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
