Description

Technical Field

[0001] This application relates to the technical field of turbine blade processing, and in particular to a marking device for turbine blades. Background Technology

[0002] like Figure 1 The turbine blades 6 shown need to be marked with model, specifications and other markings during the production and processing process. In the existing technology, laser marking machines are generally used for marking. During marking, the blades are placed flat or face down. During normal handling, the blades are placed vertically with the base facing down. When the blades are placed flat or face down, they need to be manually moved and turned. When the blades are heavy, the labor intensity of the workers is high, the production efficiency is low, and the blade body is easily bumped during the placement process, which can cause damage to the blade body. Utility Model Content

[0003] The purpose of this application is to provide a marking device for steam turbine blades to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides a marking device for steam turbine blades, employing the following technical solution:

[0005] A marking device for turbine blades includes a laser marking machine and a blade placement mechanism. The blade placement mechanism includes a double-track conveying device with a plurality of clamping and positioning components evenly installed on it. The double-track conveying device includes a support, a reduction motor, and two sets of sprockets symmetrically arranged on the support. The reduction motor drives the sprockets to work, and a chain is provided on the sprockets. The laser marking machine is installed inside the support.

[0006] The clamping and positioning assembly includes a fixed plate, a U-shaped slot, and two quick clamps. The fixed plate is fixed to the chains on both sides. A through slot is provided in the middle of the fixed plate. The U-shaped slot is fixed to the fixed plate. The quick clamps are fixed to the fixed plate and are arranged on both sides of the U-shaped slot.

[0007] Preferably, to avoid collisions with the blades, the sidewall of the opening side of the U-shaped slot is chamfered.

[0008] Preferably, the bracket is provided with a plurality of support rollers corresponding to the position of the chain.

[0009] By adopting the above technical solution and setting up support rollers, the chain can be supported, thereby ensuring that the blades can be kept in a horizontal state for marking work.

[0010] The two sets of sprockets can move synchronously.

[0011] Preferably, a feeding platform is provided next to the bracket, and a guide groove is provided on the surface of the feeding platform. One end of the guide groove can correspond to the opening of the U-shaped slot in the clamping and positioning assembly.

[0012] By adopting the above technical solution and setting up a loading platform, the staff only needs to move the blades from the transfer vehicle to the loading platform, then push them into the guide chute, and push them along the guide chute to the clamping and positioning component, making the loading process easier for the staff.

[0013] Preferably, to facilitate the operation of the blades by the staff, the feeding platform is provided with a number of ball bearings evenly distributed on the surface of the guide groove.

[0014] In summary, this application includes at least one of the following beneficial technical effects: the turbine blade marking device is equipped with a clamping and positioning component, and the blade is fixed vertically on the clamping and positioning component, which makes it easier for workers to handle and greatly reduces labor intensity. At the same time, the vertical setting of the blade makes it less likely to be damaged. By setting a double-track conveyor, continuous marking can be achieved, which greatly improves production efficiency. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 2-3 This application will be described in further detail.

[0020] This application discloses a marking device for steam turbine blades, referring to... Figure 2-3The system includes a laser marking machine 1 and a blade placement mechanism. The blade placement mechanism includes a double-track conveyor 2. Several clamping and positioning components 3 are evenly installed on the double-track conveyor 2. The double-track conveyor 2 includes a bracket 21, a reduction motor 22, and two sets of sprockets symmetrically arranged on the bracket 21. The reduction motor 22 is used to drive the sprockets to work. A chain 23 is provided on the sprockets. The laser marking machine 1 is installed in the bracket 21. The two sets of sprockets can move synchronously.

[0021] The clamping and positioning assembly 3 includes a fixed plate 31, a U-shaped slot 32, and two quick clamps 33. The fixed plate 31 is fixed on the chains 23 on both sides. A through slot 311 is provided in the middle of the fixed plate 31. The U-shaped slot 32 is fixed on the fixed plate 31. The quick clamps 33 are fixed on the fixed plate 31 and are provided on both sides of the U-shaped slot 32. A chamfer is provided on the side wall of the opening side of the U-shaped slot 32.

[0022] Reference Figure 2 The bracket 21 is provided with several support rollers 5 at the position corresponding to the chain 23.

[0023] By providing support roller 5, the chain 23 can be supported, thus ensuring that the blades can be kept horizontal for marking work.

[0024] Reference Figure 2 A loading platform 4 is provided next to the support 21. A guide groove 41 is provided on the surface of the loading platform 4. One end of the guide groove 41 can correspond to the opening of the U-shaped slot 32 in the clamping and positioning component 3. A number of balls are evenly provided on the surface of the loading platform 4 corresponding to the guide groove 41.

[0025] With the loading platform 4 in place, the staff only needs to move the blades from the transfer vehicle to the loading platform 4, then push them into the guide chute 41, and push them along the guide chute 41 to the clamping and positioning component 3, making the loading process easier for the staff.

[0026] The implementation principle of a marking device for turbine blades in this application is as follows:

[0027] The operator places the blade into the guide groove 41 of the loading platform 4, pushes the blade along the guide groove 41 into the fixing plate 31 of the clamping and positioning assembly 3, and pushes it into the U-shaped slot 32. Then, the quick clamps 33 on both sides are moved to press the blade into the fixing plate 31 vertically. The reduction motor 22 drives the chain 23 to move, which moves the blade to the top of the laser marking machine 1 for marking. During the marking process, the operators at both ends of the double-track conveyor 2 perform loading and unloading actions to achieve continuous marking action, which greatly improves production efficiency. At the same time, the blade moves vertically, which will not damage the blade, and it is also more convenient for the operator to handle.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
