Description

Technical Field

[0001] This utility model relates to the field of thread rolling machine technology, and in particular to a high-precision automatic thread rolling machine. Background Technology

[0002] Thread rolling machines are specialized equipment for producing screws. Currently, some thread rolling machines use manual feeding, placing the workpiece at a fixed thread rolling plate for thread rolling.

[0003] In existing technologies, some manually fed thread rolling machines require the operator to hold the screw between two sets of thread rolling plates and use the sliding of one set of plates to complete the thread rolling process. However, this method has certain drawbacks in actual use. For example, some screws have different thread rolling specifications, and it is difficult to accurately control the placement and angle of the screw when holding it, resulting in unstable thread accuracy and quality during the thread rolling process. Therefore, a high-precision automatic thread rolling machine is needed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-precision automatic wire rolling machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-precision automatic thread rolling machine includes a base with an inclined end face. A first thread rolling plate and a second thread rolling plate are slidably connected to the end face. Two sets of track grooves are provided on the upper end of the base, and the first and second thread rolling plates slide within these grooves. A sliding groove is provided on the upper end of the base, and a slider is slidably connected within the groove. A threaded rod is rotatably connected to the end face of the slider. A moving block is threadedly connected to the threaded section of the threaded rod. A placement frame is fixedly connected to the outer wall of the moving block. The outer wall of the placement frame is U-shaped. A drive assembly for driving the first thread rolling plate to slide is installed on the outer wall of the base, and a sliding assembly for driving the slider to slide is installed within the sliding groove.

[0007] Preferably, the drive assembly includes a turntable rotatably connected to the outer wall of the base, a connecting rod rotatably connected to the outer wall of the turntable, and the other end of the connecting rod rotatably connected to a thread rolling plate.

[0008] Preferably, the sliding assembly includes a threaded rod II rotatably connected to the inner wall of the slide groove, the slider is threadedly connected to the threaded section of the threaded rod II, and a rotating block is fixedly connected to one end of the threaded rod II.

[0010] Preferably, a hydraulic cylinder is fixedly connected to the outer wall of the base, the telescopic end of the hydraulic cylinder is fixedly connected to the thread rolling plate, and a collection box is provided on the outer wall of the base.

[0011] Preferably, a motor 1 and a motor 2 are fixedly connected to the outer wall of the base, and the motor 1 and the motor 2 are respectively coaxially fixedly connected to the turntable and the threaded rod 2.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the coordinated adjustment of threaded rod one and hydraulic cylinder, and in conjunction with the rotation of threaded rod two, can precisely adjust the height and position of the placement frame and the distance between thread rolling plate one and thread rolling plate two before thread rolling operation, ensuring that the screw is always located in the center position of the two sets of thread rolling plates during the thread rolling process.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A high-precision automatic thread rolling machine includes a base 1. The end face of the base 1 is inclined, and a thread rolling plate 4 and a thread rolling plate 7 are slidably connected to the end face. Two sets of track grooves 6 are opened at the upper end of the base 1. The thread rolling plate 4 and the thread rolling plate 7 slide in the two sets of track grooves 6 respectively. A sliding groove 16 is opened at the upper end of the base 1. A slider 10 is slidably connected in the sliding groove 16. A threaded rod 11 is rotatably connected to the end face of the slider 10. A moving block 14 is threadedly connected to the threaded section of the threaded rod 11. A placement frame 15 is fixedly connected to the outer wall of the moving block 14. The outer wall of the placement frame 15 is U-shaped. A drive assembly for driving the thread rolling plate 4 to slide is installed on the outer wall of the base 1. A sliding assembly for driving the slider 10 to slide is installed in the sliding groove 16.

[0023] Specifically, the base 1 has an inclined end face, which facilitates the natural sliding of screws during the thread rolling process, reducing manual intervention. The design of the thread rod 11 allows the placement rack 15 to be precisely adjusted to adapt to the thread rolling needs of screws of different specifications, improving the versatility and production efficiency of the equipment.

[0024] The drive assembly includes a turntable 2 rotatably connected to the outer wall of the base 1, a connecting rod 3 rotatably connected to the outer wall of the turntable 2, and the other end of the connecting rod 3 rotatably connected to the thread rolling plate 4.

[0025] Specifically, the drive assembly, through the arrangement of turntable 2 and connecting rod 3, converts the rotational motion into the linear motion of the thread rolling plate 4, ensuring that the thread rolling plate 4 slides smoothly and with uniform force.

[0026] The sliding assembly includes a threaded rod 18 rotatably connected to the inner wall of the slide groove 16, a slider 10 threadedly connected to the threaded section of the threaded rod 18, and a rotating block 12 fixedly connected to the end of the threaded rod 11.

[0027] Specifically, the threaded connection between the threaded rod 18 and the slider 10 enables the slider 10 to slide precisely within the groove 16, thereby allowing the position of the placement frame 15 to be flexibly adjusted according to the spacing between the thread rolling plate 4 and the thread rolling plate 7.

[0028] A second limiting rod 19 is fixedly connected to the inner wall of the slide 16, a first limiting rod 13 is fixedly connected to the end face of the slider 10, a moving block 14 is slidably connected to the outer wall of the first limiting rod 13, a slider 10 is slidably connected to the outer wall of the second limiting rod 19, a hydraulic cylinder 8 is fixedly connected to the outer wall of the base 1, the telescopic end of the hydraulic cylinder 8 is fixedly connected to the second thread rolling plate 7, and a collection box 5 is provided on the outer wall of the base 1.

[0029] Specifically, the design of the hydraulic cylinder 8 makes the movement of the thread rolling plate 7 more stable and the force controllable, which can adapt to screw materials of different hardness, ensure uniform pressure during the thread rolling process, and avoid thread damage. The collection box 5 facilitates the automatic collection of processed screws.

[0030] The outer wall of the base 1 is fixedly connected to motor 9 and motor 17. Motor 9 and motor 17 are respectively coaxially fixedly connected to turntable 2 and threaded rod 18.

[0031] In this invention, the device is used as follows: In the initial state, thread rolling plates 4 and 7 are in standby position, without applying pressure to the screws. At this time, the operator first performs the following adjustments according to the specifications of the screws to be processed: Before thread rolling, the operator adjusts the position of the moving block 14 by rotating the rotating block 12 at the end of the thread rod 11, thereby adjusting the height of the placement frame 15. The U-shaped design of the placement frame 15 facilitates the placement and fixing of the screws, ensuring the stability of the screws during the thread rolling process. After the thread rod 11 is adjusted, the operator starts the hydraulic cylinder 8, causing the thread rolling plate 7 to move slowly, adjusting the distance between thread rolling plates 4 and 7. To ensure the precise spacing between the two sets of thread rolling plates during the thread rolling process and avoid thread errors caused by improper spacing, and to ensure that the centerline of the placement frame 15 is located at the center point of the two sets of thread rolling plates, the thread rod 18 can be rotated by the motor 17, and the slider 10 can be precisely slid in the groove 16 through the threaded connection. Thus, the position of the placement frame 15 can be flexibly adjusted according to the spacing between the thread rolling plate 4 and the thread rolling plate 7.

[0032] When the device is started, during the thread rolling process, the screw is placed on the placement rack 15. Then, the motor 9 drives the turntable 2 to rotate. The turntable 2 converts the rotational motion into the linear motion of the thread rolling plate 4 through the connecting rod 3. As the thread rolling plate 4 slides, the screw is gradually clamped between the two sets of thread rolling plates. The thread grooves on the thread rolling plate begin to compress the screw surface to form the required thread.

[0033] After the thread rolling is completed, the screw will naturally slide into the collection box 5 due to its own weight and no longer being squeezed by the thread rolling plate, thus completing the thread rolling process.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
