Description

Technical Field

[0001] The utility model relates to the technical field of turbine production, in particular to a clamping and positioning device for turbine processing. Background Art

[0002] A turbine is a rotating mechanical component that converts the energy of a fluid into mechanical work. A turbine is usually composed of a series of curved blades. When a fluid with a certain pressure and speed (such as gas or liquid) hits the turbine blades, the blades will rotate. Turbines are widely used in many fields, such as turbochargers in automobile engines, aircraft engines, steam turbines, and water turbines.

[0003] Existing, such as China Patent Publication No.: CN218776442U, a clamping and positioning device for turbine production and processing includes a belt-mouth box, the right side of the belt-mouth box is fixedly connected with a motor, the output end of the motor penetrates into the inside of the belt-mouth box and is fixedly connected with a screw, both sides of the surface of the screw are threadedly connected with clamping plates, the top of the clamping plate extends to the top of the belt-mouth box, the inside of the clamping plate is slidably connected with a pressure plate, and the bottom of the pressure plate is fixedly connected with a T-shaped plate. The utility model drives the two clamping plates to approach each other by the motor and the screw to clamp and fix the turbine on the left and right, and then drives the pressure plate to move downward through the inclined opening, the positioning plate, the concave sleeve and the T-shaped plate to press and fix the turbine, thereby having the advantage of better fixing effect, and solving the problem that the existing clamping and positioning device can only clamp the turbine on both sides during use, and cannot press and fix the turbine downward, which causes the turbine to easily warp during processing.

[0004] Although the above patent has the advantage of better fixing effect, the existing turbine clamping and positioning device usually adopts a power source to push the clamping plate downward and then press the edge of the turbine to clamp and position, and the distance between the clamping plates in relative directions is smaller than the diameter of the turbine edge. Therefore, when placing the turbine, it is easy to be scratched and damaged by the clamping plates, and the operation is more troublesome. Therefore, in response to the above problems, we propose a new type of clamping and positioning device for turbine processing. Utility Model Content

[0005] The utility model mainly provides a clamping and positioning device for turbine processing which is easy to operate and can effectively clamp and position the turbine.

[0006] To achieve the above object, the utility model adopts the following technical solutions: A clamping and positioning device for turbine machining, including a bottom plate. A plurality of support columns are fixedly connected to the top of the bottom plate, and a tooling table is fixedly connected between the tops of the plurality of support columns. A driving mechanism is arranged at the bottom of the tooling table, and a plurality of clamping mechanisms are arranged between the driving mechanism and the bottom plate. The four clamping mechanisms all include a first rotating seat. The four first rotating seats are equidistantly and fixedly connected to the top of the bottom plate near the edge. A first rotating shaft is fixedly connected between the inner surfaces of the first rotating seats. A first inclined plate is rotatably connected to the outer surface of the first rotating shaft. An L-shaped plate is fixedly connected to the top of the first inclined plate. A clamping plate is fixedly connected to the inner top of the L-shaped plate near the edge.

[0007] Preferably, a limiting ring is fixedly connected to the top of the tooling table. Second rotating seats are symmetrically and fixedly connected to the outer surface of one side of the L-shaped plate near the middle. A second rotating shaft is rotatably connected between the outer surfaces of the second rotating seats. The limiting ring is mainly used for limiting the turbine workpiece, and the second rotating seat is mainly used for installing the second rotating shaft on the surface of the L-shaped plate.

[0008] Preferably, the driving mechanism includes an electric push rod. The electric push rod is fixedly connected to the center of the bottom of the tooling table. A push plate is fixedly connected to the bottom end of the electric push rod. By setting the electric push rod, it plays a role of providing a pushing and pulling force for the push plate. After starting the electric push rod, it can drive the push plate to move up or down.

[0009] Preferably, third rotating seats are fixedly connected to the outer surfaces around the push plate. A third rotating shaft is rotatably connected between the inner surfaces of the third rotating seats. The third rotating shaft is rotatably connected to the push plate through the third rotating seat, and the push plate is a square plate member. The four third rotating seats are respectively fixedly connected to the four outer surfaces of the push plate.

[0010] Preferably, a pulling plate is rotatably connected to the outer surface of the third rotating shaft. The pulling plate is inclined and is rotatably connected to the second rotating shaft at a position near the top. The pulling plate can rotate between the bottom and the push plate through the third rotating shaft, and can rotate between the top and the L-shaped plate through the second rotating shaft.

[0011] Preferably, a rubber pad is adhesively connected to the bottom of the clamping plate. A plurality of anti-slip grooves are equidistantly formed at the bottom of the rubber pad. By setting the rubber pad, it plays a role of increasing the friction between the clamping plate and the surface of the turbine workpiece, and by forming anti-slip grooves at the bottom of the rubber pad, it plays a role of further improving the friction between the clamping plate and the turbine workpiece, thereby improving the clamping and positioning effect on the turbine workpiece.

[0012] Preferably, four travel switches are equidistantly embedded on the outer surface of the workbench, and the four travel switches are respectively matched with four L-shaped plates. The support columns and the L-shaped plates are staggered. After the L-shaped plates are rotated to a vertical state, they will touch the travel switches. When a device failure causes the L-shaped plates to continue to rotate inward, the travel switches will be triggered to send out electrical signals and forcibly cut off the power supply of the electric push rod, thereby ensuring the safe operation of the device. The travel switches are electrically connected to the electric push rod through an external line, and a controller is provided between the two. This is an existing mature technology and will not be elaborated on here.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, after the electric push rod is started to drive the push plate to move upward, the bottom of the pull plate will move upward and rotate, thereby generating an outward oblique thrust for the position of the L-shaped plate near the top and rotating with the L-shaped plate, so that the four L-shaped plates will synchronously rotate outward with the corresponding first rotating shaft as the center, thereby moving the clamping plate away from the top of the workbench, and the turbine workpiece can be easily placed in the limit ring. Subsequently, the electric push rod is controlled to push the push plate to move downward, which can drive the four L-shaped plates to return to the vertical state and then drive the four clamping plates to firmly clamp the edge of the turbine workpiece. The overall operation is convenient, the clamping and positioning effect is good, and it is not easy to scratch the turbine workpiece when taking it.

[0015] 2. In the utility model, the friction between the clamping plate and the surface of the turbine workpiece is increased by arranging a rubber pad, and the friction between the clamping plate and the turbine workpiece is further increased by opening an anti-skid groove at the bottom of the rubber pad, thereby improving the clamping and positioning effect of the turbine workpiece. In addition, the L-shaped plate will touch the travel switch after rotating to a vertical state. When the device fails and causes the L-shaped plate to continue to rotate inward, the travel switch will be triggered to send an electrical signal and forcibly cut off the power supply of the electric push rod, thereby ensuring the safe operation of the device.

A clamping plate 205 is fixedly connected to the inner top of the L-shaped plate 204 near the edge.

[0025] As Figures 1 - 4 shown, a limit ring 13 is fixedly connected to the top of the tooling table 12. Second rotating seats 208 are symmetrically and fixedly connected to the outer surface of one side of the L-shaped plate 204 near the middle. A second rotating shaft 209 is rotatably connected between the outer surfaces of the second rotating seats 208. The limit ring 13 is mainly used for limiting the turbine workpiece. The second rotating seat 208 is mainly used for installing the second rotating shaft 209 on the surface of the L-shaped plate 204.

[0026] As Figure 1 、 Figure 2and Figure 5 As shown in Figure 5 , the driving mechanism 3 includes an electric push rod 301. The electric push rod 301 is fixedly connected to the center of the bottom of the tooling table 12. The bottom end of the electric push rod 301 is fixedly connected to a push plate 302. By setting the electric push rod 301, it plays a role of providing a pushing and pulling force for the push plate 302. After starting the electric push rod 301, it can drive the push plate 302 to move up or down.

[0027] As Figure 1 , Figure 2 and Figure 5 As shown in Figure 2 and Figure 5 , the outer surfaces around the push plate 302 are all fixedly connected with third rotating seats 303. A third rotating shaft 304 is rotatably connected between the inner walls of the third rotating seats 303. The third rotating shaft 304 is rotatably connected to the push plate 302 through the third rotating seats 303. And the push plate 302 is a square plate member. The four third rotating seats 303 are respectively fixedly connected to the four outer surfaces of the push plate 302.

[0028] As Figures 1 - 3 and Figure 5 As shown in Figures 1 - 3 and Figure 5 , a pull plate 305 is rotatably connected to the outer surface of the third rotating shaft 304. The pull plate 305 is inclined and is rotatably connected to the second rotating shaft 209 at a position near the top. The pull plate 305 can rotate between the bottom and the push plate 302 through the third rotating shaft 304, and the top can rotate with the L-shaped plate 204 through the second rotating shaft 209.

[0029] As Figures 1 - 3 and Figure 5 As shown in Figures 1 - 3 and Figure 5 , a rubber pad 206 is adhesively connected to the bottom of the clamping plate 205. A plurality of anti-slip grooves 207 are equidistantly opened at the bottom of the rubber pad 206. By setting the rubber pad 206, it plays a role of increasing the friction between the clamping plate 205 and the surface of the turbine workpiece. And by opening the anti-slip grooves 207 at the bottom of the rubber pad 206, it plays a role of further improving the friction between the clamping plate 205 and the turbine workpiece, thereby improving the clamping and positioning effect on the turbine workpiece.

[0030] As Figures 1 - 5 As shown in Figures 1 - 5 , four travel switches 14 are equidistantly embedded on the outer surface of the tooling table 12. The four travel switches 14 are respectively matched with the four L-shaped plates 204. The positions of the support columns 11 and the L-shaped plates 204 are staggered. When the L-shaped plate 204 rotates to the vertical state, it will touch the travel switch 14. When the device fails and causes the L-shaped plate 204 to continue to rotate inward, it will trigger the travel switch 14 to send an electrical signal and forcibly cut off the power supply of the electric push rod 301, ensuring the safe operation of the device. The travel switch 14 is electrically connected to the electric push rod 301 through an external circuit, and a controller is provided for matching between the two. This is a mature existing technology and will not be elaborated here.

[0031] Usage method and working principle of the present device: When using this device for clamping and positioning during the turbine machining process, first start the electric push rod 301 to drive the push plate 302 to move upward. At this time, the bottom height of the pull plate 305 rises, and under the action of the third rotating shaft 304, it rotates with the push plate 302. During this process, the top end of the pull plate 305 will generate an outward oblique thrust on the position of the L-shaped plate 204 near the upper part, and rotates between the second rotating shaft 209 and the L-shaped plate 204. Therefore, the four L-shaped plates 204 will synchronously rotate outward with the corresponding first rotating shaft 202 as the center, so that the clamping plate 205 moves away from above the tooling table 12. At this time, the turbine workpiece can be easily placed into the limit ring 13. Subsequently, control the electric push rod 301 to push the push plate 302 downward, which can drive the four L-shaped plates 204 to return to the vertical state and then drive the four clamping plates 205 to firmly clamp the edge of the turbine workpiece. The overall operation is convenient, the clamping and positioning effect is good, and it is not easy to cause scratches when taking and placing the turbine workpiece. At the same time, by setting the rubber pad 206, it plays a role in increasing the friction between the clamping plate 205 and the surface of the turbine workpiece, and by opening the anti-slip groove 207 at the bottom of the rubber pad 206, it further improves the friction between the clamping plate 205 and the turbine workpiece, thereby improving the clamping and positioning effect of the turbine workpiece. Moreover, when the L-shaped plate 204 rotates to the vertical state, it will touch the travel switch 14. When the device fails and causes the L-shaped plate 204 to continue to rotate inward, the travel switch 14 will be triggered to send an electrical signal and forcibly cut off the power supply of the electric push rod 301, ensuring the safe operation of the device.
