Traditional workpiece positioning and clamping methods often have problems such as complex operation, low positioning accuracy, and unstable clamping. These problems not only affect the machining quality of workpieces but also reduce production efficiency and increase production costs.

[0003] However, when using existing large workpiece positioning auxiliary devices, multiple steps and complex operations are usually required to achieve workpiece positioning and clamping. This not only requires operators to have a high skill level but also easily causes positioning errors due to human factors.

[0024] The following combines the accompanying drawings and makes a more detailed description of the large workpiece positioning auxiliary device based on a floor boring machine of the present utility model through specific implementation modes.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0026] This embodiment discloses a large workpiece positioning auxiliary device based on a floor boring machine, with beneficial effects. Refer to Figure 1 、 Figure 2 It mainly includes a support frame 1, on the side wall of which there is a transmission member. The transmission member includes a rocker 2, a linkage plate 3 and a threaded sleeve 4. The rocker 2 is rotatably connected to the side wall of the support frame 1 and is fixedly connected with a threaded transmission rod 5. The two sides of the threaded sleeve 4 are hinged to the linkage plate 3 through pin shafts and are threadedly connected with the threaded transmission rod 5. It also includes a rotating shaft 9, one end of which is fixed to the linkage plate 3 and is connected to the top of the support frame 1 through a bearing 7. A driving motor 6 is installed on the side wall of the rotating shaft 9, and its output shaft is connected with a first rotating gear 10. A second rotating gear 11 is rotatably connected to the side wall of the rotating shaft 9 and meshes with the first rotating gear 10.

[0027] The support frame 1 serves as the foundation of the entire device and is firmly fixed to the floor boring machine. A transmission member system is ingeniously designed on its side wall. The transmission member is composed of a rocker 2, a linkage plate 3 and a threaded sleeve 4. Among them, the rocker 2 is connected to the threaded sleeve 4 through a threaded transmission rod 5 to form a precise threaded transmission mechanism. When the operator rotates the rocker 2, the threaded transmission rod 5 drives the threaded sleeve 4 to move axially along it, and then drives the linkage plate 3 and the rotating shaft 9 connected thereto to rotate through the hinge relationship between the pin shaft and the linkage plate 3. This design not only realizes the angle transformation of the workpiece, but also ensures the stability of positioning through the self-locking property of the threaded transmission.

[0028] The rotating shaft 9, as a key component connecting the transmission part and the clamping mechanism, has one end fixed to the linkage plate 3 and the other end connected to the top of the support frame 1 through a bearing 7, achieving flexible rotational movement. At the same time, a driving motor 6 is installed on the side wall of the rotating shaft 9, and its output shaft is connected to the first rotating gear 10, which meshes with the second rotating gear 11. This design enables the driving motor 6 to directly drive the clamping mechanism and the workpiece to perform rotational processing when it starts, greatly improving the processing efficiency and flexibility.

[0029] Refer to Figure 1 、 Figure 3 , the workpiece is firmly clamped by driving the threaded column through the rotating gear ring, enhancing the flexibility and processing efficiency of the device. The clamping piece 8 is detachably fixed to the top of the second rotating gear 11. The clamping piece 8 includes a limiting cylinder 801, a threaded column 802, a rotating gear ring 803, a limiting piece 804 and a transmission gear 805. The limiting cylinder 801 is detachably fixed to the top of the second rotating gear 11. The rotating gear ring 803 is rotatably sleeved on the outer surface top of the limiting cylinder 801. The limiting pieces 804 are evenly distributed and fixed on the outer surface of the limiting cylinder 801. The transmission gear 805 is rotatably arranged on the inner side wall of the limiting piece 804. Threaded holes adapted to the threaded column 802 are provided at the middle positions of the limiting piece 804 and the transmission gear 805.

[0030] As one of the key components of this device, the clamping piece 8 is designed by fully considering the clamping requirements and processing characteristics of the workpiece. The limiting cylinder 801, as the main structure of the clamping piece, is detachably and fixedly connected to the top of the second rotating gear 11, facilitating replacement or adjustment according to processing requirements.

[0031] The rotating gear ring 803 is cleverly rotatably sleeved on the outer surface top of the limiting cylinder 801, and the internal transmission mechanism can be driven by rotating the gear ring. The limiting pieces 804 are evenly distributed on the outer surface of the limiting cylinder 801, playing a role in supporting and fixing the transmission gear 805. The transmission gear 805 is rotatably arranged on the inner side wall of the limiting piece 804, forming a precise threaded fit relationship with the threaded column 802.

[0032] When the operator rotates the rotating gear ring 803, the transmission gear 805 rotates accordingly. Since threaded holes adapted to the threaded column 802 are provided at the middle positions of the transmission gear 805 and the limiting piece 804, the rotation of the transmission gear 805 will drive the threaded column 802 to move up and down in the limiting cylinder 801. By adjusting the extending length of the threaded column 802, the firm clamping of the workpiece can be achieved. This design not only simplifies the clamping operation process but also improves the clamping stability and flexibility.

[0033] The working principle of the large workpiece positioning and assisting device based on the floor boring machine of the present utility model:

[0034] Initial state and workpiece placement:

[0035] In the initial state, all components are in the inactive state, and the threaded post 802 of the clamping member 8 is in the unclamped position.

[0036] Place the large workpiece to be processed inside the limiting cylinder 801 of the clamping member 8. At this time, the workpiece is in a free state and not fixed.

[0037] Workpiece clamping:

[0038] The operator manually rotates or uses an external tool to rotate the gear ring 803. The rotating gear ring 803 meshes with the transmission gear 805. When the gear ring 803 rotates, it drives the transmission gear 805 to rotate on the track inside the limiting piece 804.

[0039] Threaded holes adapted to the threaded post 802 are provided both inside the transmission gear 805 and at the middle position between the limiting pieces 804. As the transmission gear 805 rotates, its threads interact with the threads of the threaded post 802, pushing the threaded post 802 to move upward inside the limiting cylinder 801.

[0040] Since there are three evenly distributed threaded posts 802 inside the limiting cylinder 801, they are simultaneously driven by the transmission gear 805 to move upward, thereby clamping the workpiece evenly. This design ensures the stability and accuracy of clamping.

[0041] Workpiece angle transformation:

[0042] When the angle of the workpiece needs to be transformed, the operator rotates the rocker 2. The rocker 2 is fixedly connected to the threaded transmission rod 5, so the rotation of the rocker 2 drives the threaded transmission rod 5 to rotate.

[0043] The threaded transmission rod 5 is threadedly connected to the threaded sleeve 4. When the threaded transmission rod 5 rotates, the threaded sleeve 4 moves along the axial direction of the threaded transmission rod 5.

[0044] Both sides of the threaded sleeve 4 are hinged to the linkage plate 3 through pin shafts. Therefore, the movement of the threaded sleeve 4 drives the linkage plate 3 to rotate around an axis of the support frame.

[0045] The linkage plate 3 is connected to one end of the rotating shaft 9, and the other end of the rotating shaft 9 is connected to the top of the support frame through a bearing. Therefore, the rotation of the linkage plate 3 drives the rotating shaft 9 and the clamping member 8 and the workpiece fixed on the rotating shaft 9 to rotate together, realizing the angle transformation of the workpiece.

[0046] Workpiece rotation angle machining:

[0047] When it is necessary to perform rotary angle machining on the workpiece, the drive motor 6 is started. The output shaft of the drive motor 6 is connected to the first rotating gear 10. Therefore, the rotation of the drive motor 6 will drive the first rotating gear 10 to rotate.

[0048] The first rotating gear 10 meshes with the second rotating gear 11. Therefore, the rotation of the first rotating gear 10 will drive the second rotating gear 11 to rotate.

[0049] The second rotating gear 11 is fixed on the rotating shaft 9 and is connected to the bottom of the clamping member 8. Therefore, the rotation of the second rotating gear 11 will drive the clamping member 8 and the workpiece inside to rotate together, realizing the rotary angle machining of the workpiece.
