A conveying device for machining stationary blades

Abstract

This utility model discloses a conveying device for processing stationary blades, applied in the field of conveying device technology. It includes a conveying base with a connecting seat inside. The conveying base incorporates a moving mechanism; the connecting seat can move a support block, which in turn moves a placement plate. When the stationary blade raw material is placed on the placement plate, it moves between two clamps on the machine tool. A hydraulic cylinder adjusts the height of the placement plate, allowing the axial position of the raw material to align with the two clamps. When the two clamps hold the raw material, if the distance between the raw material and the clamps is different, the guide wheel allows the raw material to move on the placement plate, ultimately ensuring perfect clamping by the two clamps and improving the feeding speed.

Description

Technical Field

[0001] This utility model belongs to the field of conveying device technology, and specifically relates to a conveying device for processing stationary blades. Background Technology

[0002] Currently, multi-axis linkage machine tools are required for the machining of turbine stationary blades. The process involves using two rotating jigs on the multi-axis linkage machine tool to hold the raw material of the turbine stationary blade, such as a metal block, and then turning it into shape.

[0003] However, when the raw material for the stationary blades is fed between the two rotating clamps, the traditional method of conveying the raw material for the stationary blades of the steam turbine is to use hoisting equipment to lift and move the raw material between the two clamps because the raw material is heavy. Although this method can achieve the purpose of conveying the raw material, the hoisting equipment cannot accurately move the raw material to the specified position. It requires the staff to manually move the raw material, which is not only labor-intensive for the staff, but also slow. Utility Model Content

[0004] The purpose of this utility model is to provide a conveying device for processing stationary blades, which has the advantages of rapid feeding and strong applicability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a conveying device for processing stationary blades, including a conveying base, a connecting base inside the conveying base, a moving mechanism inside the conveying base, a support block fixedly connected to the connecting base on the top of the conveying base, a placement plate on the top of the support block, a hydraulic cylinder fixedly connected to the placement plate embedded in the top of the support block, clamps symmetrically arranged on the top of the placement plate, guide wheels fitted inside the clamps and on the top of the placement plate, a groove opened on the top of the placement plate, an adjusting screw rotatably connected inside the groove via a bearing, one end of the adjusting screw penetrating to the outside of the placement plate and bolted to a first servo motor fixedly connected to the placement plate, and a connecting block bolted to the clamp is symmetrically threaded on the surface of the adjusting screw.

[0006] The above technical solution is as follows: This utility model has a moving mechanism designed inside the conveyor seat, which can drive the connecting seat to move. The connecting seat can drive the support block to move, and the support block can drive the placement plate to move. When the stationary blade raw material is placed on the placement plate, it can be moved between the two clamps of the machine tool. Through the action of the hydraulic cylinder, the height of the placement plate can be adjusted so that the axial position of the stationary blade raw material can be matched with the two clamps. When the two clamps of the machine tool clamp the stationary blade raw material, if the distance between the stationary blade raw material and the two clamps is different, the stationary blade raw material can move on the placement plate under the action of the guide wheel, so that the stationary blade raw material is perfectly clamped by the two clamps of the machine tool, which improves the feeding speed. By designing an adjusting screw inside the groove of the placement plate, the adjusting screw can be driven to rotate by the action of the first servo motor. Under the action of the connecting block, the distance between the two clamps can be adjusted so that the guide wheel on the clamp can contact and limit the stationary blade raw material of different sizes, which improves the applicability of this device.

[0007] The present invention is further configured such that the moving mechanism includes a stroke screw rotatably connected to the conveyor seat, the stroke screw being threadedly connected to the connecting seat, and one end of the stroke screw extending through to the outside of the conveyor seat and being fixedly connected to a second servo motor.

[0008] The above technical solution is adopted: when the second servo motor is started, it can drive the stroke screw to rotate. The rotation of the stroke screw can drive the connecting seat to move inside the conveyor seat, thereby achieving the purpose of adjusting the position of the top placement plate.

[0009] The present invention is further configured such that sliding rods are symmetrically bolted inside the conveying seat, and the sliding rods are slidably connected to the connecting seat.

[0010] By adopting the above technical solution, when the stroke screw drives the connecting seat to move inside the conveyor seat, the connecting seat can be slidably limited.

[0011] The present invention is further configured such that guide blocks are symmetrically mounted on the bottom of the clamp, and guide grooves that are slidably connected to the guide blocks are provided on the top of the placement plate.

[0012] The above technical solution is adopted to slide and limit the clamp when it moves on the placement plate, and to reduce the friction when the clamp moves.

[0013] The present invention is further configured such that a plurality of guide rods are slidably connected to the top of the support block, and the top of the guide rods is fixedly connected to the bottom of the placement plate.

[0014] The above technical solution allows for lifting and limiting of the placement plate when it is lifted by a hydraulic cylinder.

[0015] The present invention is further configured such that the bottom of the conveyor seat is fixedly connected with four support legs.

[0016] The above technical solution is adopted to support the conveyor seat.

[0017] The present invention is further configured such that limit blocks are symmetrically bolted to the surface of the second servo motor, and the limit blocks are fixedly connected to one end of the conveyor seat.

[0018] The above technical solution facilitates the fixing of the second servo motor on the conveyor base.

[0019] In summary, this utility model has the following beneficial effects: 1. This utility model has a moving mechanism designed inside the conveyor seat, which can drive the connecting seat to move. The connecting seat can drive the support block to move, and the support block can drive the placement plate to move. When the stationary blade raw material is placed on the placement plate, it can be moved between the two clamps of the machine tool. Through the action of the hydraulic cylinder, the height of the placement plate can be adjusted so that the axial position of the stationary blade raw material can be matched with the two clamps. When the two clamps of the machine tool clamp the stationary blade raw material, if the distance between the stationary blade raw material and the two clamps is different, the stationary blade raw material can move on the placement plate under the action of the guide wheel. Finally, the stationary blade raw material is perfectly clamped by the two clamps of the machine tool, which improves the feeding speed. 2. This utility model has an adjusting screw designed inside the groove of the placement plate. The first servo motor can drive the adjusting screw to rotate, and under the action of the connecting block, it can drive the distance between the two clamps to be adjusted, so that the guide wheels on the clamps can contact and limit the raw materials of different sizes of stationary blades, thereby improving the applicability of this device.
