Abstract
Description
Technical Field
[0001] This utility model relates to the field of parts manufacturing technology, specifically a compact brake-type DD skew turntable. Background Technology
[0002] The compact, brake-type DD skew rotary table is an advanced rotary worktable and an ideal accessory for CNC machine tools such as machining centers and drilling and tapping centers. It can be used for five-axis linkage machining of complex parts, enabling multi-angle and multi-directional machining of workpieces, improving the machining quality and production efficiency. With its integrated compact structure, the motor, rotary table, braking device and other components are highly integrated, greatly reducing the size and floor space of the equipment, making it more suitable for use in space-constrained working environments, and also facilitating integration and matching with other equipment.
[0003] Existing compact brake-type DD skew rotary tables, for some applications with extremely high machining accuracy requirements, even if the required load is not large, require additional support to reduce the slight deformation of the rotary shaft caused by its own weight or minor vibrations, thereby ensuring machining accuracy. Some rotary shafts need to bear large loads during operation, especially when there are cantilever loads or eccentric loads. The support of the base alone may not be sufficient to guarantee its stability and accuracy, resulting in poor support stability for the rotary shaft. Utility Model Content
[0004] The purpose of this invention is to provide a compact, brake-type DD skew turntable to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides a compact brake-type DD skew turntable, including an inclined shaft, a connecting member movably disposed on the outside of the inclined shaft, a rotating shaft fixedly connected to one end of the connecting member, a limiting plate fixedly connected to the outer wall of the connecting member, and three clamping plates equidistantly slidably connected to the top of the limiting plate.
[0006] Furthermore, a rubber pad is fixedly connected to the inner wall of the limiting plate.
[0007] Furthermore, the top of the limiting plate is provided with three sliding grooves at equal intervals, a slider is slidably connected inside the sliding groove, a locking rod is fixedly sleeved inside the slider, and the top end of the locking rod is fixedly connected to the adjacent clamping plate.
[0008] Furthermore, two ball bearings are rotatably connected to both sides of the slider.
[0009] Furthermore, a fixing frame is fixedly sleeved on the outer wall of the connector, and the limiting plate is fixedly connected to the fixing frame.
[0010] Furthermore, a protective shell is fixedly connected to one side of the fixing frame, a retaining seat is fixedly connected to the inner bottom surface of the protective shell, a bearing is fixedly connected inside the retaining seat, a shaft is provided inside the protective shell, the shaft passes through the inner ring of the bearing and is fixedly connected to it, an adjustment plate is fixedly connected to the top of the shaft, and three arc-shaped grooves are equidistantly opened on the top of the adjustment plate, and the bottom end of the retaining rod is movably engaged in the interior of the adjacent arc-shaped groove.
[0011] Furthermore, a toothed ring is fixedly sleeved on the outer wall of the control plate, an electric push rod is fixedly connected to the inner bottom surface of the protective shell, and a rack is fixedly connected to the output end of the electric push rod, the rack meshing with the toothed ring.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] By limiting the slider with a sliding groove, the sliding limit of multiple clamping plates is achieved. The electric push rod is activated to drive the rack to move. Through the transmission of the rack and gear ring, the control plate is driven to rotate. The control plate guides the slider to move through multiple arc grooves, thereby driving the clamping rod to move the clamping plates. The multiple clamping plates are synchronously controlled, so that the multiple clamping plates clamp the rotating shaft at the same time. The control synchronization is higher. By using multiple clamping plates to clamp and limit the rotating shaft from multiple angles, the rotating shaft can be effectively supported and the force can be distributed, thereby improving the processing stability and accuracy, and making it convenient to use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-5 This utility model provides a technical solution: a compact brake-type DD oblique turntable, including an inclined shaft 10, a connector 12 is movably arranged on the outside of the inclined shaft 10, a rotating shaft 11 is fixedly connected to one end of the connector 12, a limiting plate 13 is fixedly connected to the outer wall of the connector 12, and three clamping plates 131 are equidistantly slidably connected to the top of the limiting plate 13.
[0021] In specific implementation, the sliding limit of the slider 155 by the slide groove 132 realizes the sliding limit of multiple clamping plates 131. The multiple clamping plates 131 clamp and limit the rotating shaft 11 from multiple angles, which can effectively support the rotating shaft 11 and share the force. The electric push rod 158 is activated to drive the rack 159 to move. The transmission of the rack 159 and the gear ring 157 drives the control plate 152 to rotate. The control plate 152 guides the slider 155 to move through multiple arc grooves 153, thereby driving the clamping rod 154 to move the clamping plates 131. The multiple clamping plates 131 are synchronously controlled, so that the multiple clamping plates 131 clamp the rotating shaft 11 synchronously, resulting in higher control synchronization and more stable support.
[0022] See Figure 3 A rubber pad 133 is fixedly connected to the inner wall of the limiting plate 13.
[0023] In practice, the rubber pad 133 ensures that the clamping plate 131 is in close contact with the outside of the rotating shaft 11, thereby enhancing the stability of the rotation shaft 11.
[0024] See Figure 4 The top of the limiting plate 13 is provided with three sliding grooves 132 at equal intervals. A slider 155 is slidably connected inside the sliding groove 132. A locking rod 154 is fixedly sleeved inside the slider 155. The top of the locking rod 154 is fixedly connected to the adjacent clamping plate 131.
[0025] Two ball bearings 156 are rotatably connected to both sides of the slider 155.
[0026] In specific implementation, the sliding limit of the slider 155 by the slide groove 132 realizes the sliding limit of multiple clamping plates 131. The multiple clamping plates 131 clamp and limit the rotating shaft 11 from multiple angles, which can effectively support the rotating shaft 11 and share the force. The setting of the ball bearings 156 reduces the friction between the slider 155 and the slide groove 132, making the control of the multiple clamping plates 131 smoother.
[0027] See Figure 1-5 A fixing frame 15 is fixedly sleeved on the outer wall of the connector 12, and the limiting plate 13 is fixedly connected to the fixing frame 15.
[0028] A protective shell 151 is fixedly connected to one side of the fixed frame 15. A card seat 14 is fixedly connected to the inner bottom surface of the protective shell 151. A bearing 141 is fixedly connected inside the card seat 14. A shaft 142 is provided inside the protective shell 151. The shaft 142 passes through the inner ring of the bearing 141 and is fixedly connected to it. An adjustment plate 152 is fixedly connected to the top of the shaft 142. Three arc-shaped grooves 153 are equidistantly opened on the top of the adjustment plate 152. The bottom end of the card rod 154 is movably engaged inside the adjacent arc-shaped grooves 153.
[0029] A toothed ring 157 is fixedly sleeved on the outer wall of the control plate 152. An electric push rod 158 is fixedly connected to the inner bottom surface of the protective shell 151. A rack 159 is fixedly connected to the output end of the electric push rod 158. The rack 159 meshes with the toothed ring 157.
[0030] In practice, the rotation of the control plate 152 is limited by the limiting position of the shaft 142 by the clamping seat 14. The electric push rod 158 is activated to drive the rack 159 to move. The control plate 152 is rotated through the transmission of the rack 159 and the gear ring 157. The control plate 152 guides the slider 155 to move through multiple arc grooves 153, thereby driving the clamping rod 154 to move the clamping plate 131. The multiple clamping plates 131 are synchronously controlled, so that the multiple clamping plates 131 clamp the rotating shaft 11 synchronously, resulting in higher control synchronization and more stable support.
[0031] Working principle: The sliding limit of the slider 155 by the slide groove 132 realizes the sliding limit of multiple clamping plates 131. The multiple clamping plates 131 clamp and limit the rotating shaft 11 from multiple angles, which can effectively support the rotating shaft 11 and share the force. The electric push rod 158 is activated to drive the rack 159 to move. The transmission of the rack 159 and the gear ring 157 drives the control plate 152 to rotate. The control plate 152 guides the slider 155 to move through multiple arc grooves 153, thereby driving the clamping rod 154 to move the clamping plates 131. The multiple clamping plates 131 are synchronously controlled, so that the multiple clamping plates 131 clamp the rotating shaft 11 synchronously, resulting in higher control synchronization and more stable support.
