Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, specifically to a welding clamping fixture for solar thermal power generation reflectors. Background Technology

[0002] Reflectors are the core components in solar thermal power generation, responsible for energy concentration. Their function is to improve thermal energy conversion efficiency by reflecting and focusing sunlight. Reflectors include curved reflectors and flat reflectors. Flat reflectors refer to mirrors with flat or slightly curved surfaces, which are arranged in an array to precisely reflect sunlight to a central heat-absorbing tower or other heat collection devices.

[0003] Currently, when welding two planar reflectors, the two reflectors to be welded need to be neatly placed on the processing table, and then the staff manually operate the clamps to hold and limit them, which results in poor alignment accuracy between the two planar reflectors and affects the welding effect. Utility Model Content

[0004] The purpose of this invention is to provide a welding clamping fixture for solar thermal power generation reflectors, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding clamping fixture for solar thermal power generation reflectors, comprising:

[0006] A support plate is provided, with a welding table fixed on the upper middle part of the support plate. The welding table has grooves on both the left and right sides of the front and rear sides. Multiple rollers are installed in the grooves at equal intervals. A first electric push rod is installed in the middle of both the front and rear sides of the support plate. The output end of the first electric push rod is connected to a push plate. A second electric push rod is installed at both the left and right ends of the lower middle part of the support plate. The output ends of the two second electric push rods pass through the support plate and are connected to a pressure frame.

[0007] Two limiting mechanisms are respectively installed on the front and rear parts of the support plate. Each limiting mechanism includes two limiting components and a driving component that drives the two limiting components to move synchronously. Each limiting component includes a movable seat, and multiple limiting rollers are rotatably mounted at equal intervals on the upper side of the movable seat.

[0008] Preferably, the pressure frame is located above the welding table, and a welding port is provided on the pressure frame. The pressure frame presses on two flat reflectors, and the welding port exposes the mating part of the flat reflectors, which facilitates welding with a welding gun.

[0009] Preferably, the plurality of limiting rollers pass through the corresponding grooves, and the plurality of limiting rollers are spaced apart from the plurality of rollers.

[0010] Preferably, the lower left and right edges of the bearing plate are both fixed with side plates;

[0011] The drive assembly includes a servo motor, a first lead screw, and a second lead screw. The servo motor is mounted on a side plate, and its output end passes through the side plate and is connected to the first lead screw. The end of the first lead screw away from the servo motor is connected to the second lead screw, and the end of the second lead screw away from the first lead screw is rotatably connected to the side plate. The second lead screw and the first lead screw are symmetrically arranged. A nut seat is fitted on both the first and second lead screws, and the nut seat is connected to a corresponding movable seat.

[0012] The servo motor drives the first and second lead screws to rotate, causing the nut seats on the first and second lead screws to move closer or further apart, thereby causing the left and right limit components to move closer or further apart.

[0013] Preferably, the lower front and rear parts of the movable seat are fixed with collars, and the two collars symmetrically arranged together slide and nest a limiting rod. The two ends of the limiting rod are respectively connected to the two side plates, so that the limiting component moves stably and will not deviate.

[0014] Preferably, the top surface of the roller is flush with the upper side of the welding table, so that one side of the reflector moving on the roller can be moved onto the welding table, facilitating the alignment of the two planar reflectors.

[0015] Preferably, a sliding groove is provided between the two grooves on the left and right sides, and the lower end of the push plate is slidably nested in the sliding groove, so that the push plate moves stably and can effectively push the reflector.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. By placing two flat reflectors on the front and back of the welding table, two limiting mechanisms work to squeeze and limit the two flat reflectors. At the same time, two first electric push rods work to push the two flat reflectors through the push plate, so that the side of the two flat reflectors that is close to each other moves to the welding table and aligns with each other. The operation is simple and convenient, and the accuracy of the alignment of the two flat reflectors is improved.

[0018] 2. By synchronously operating two second electric push rods, the pressure frame is moved downward, pressing against the two flat reflectors to prevent the mating parts of the two flat reflectors from lifting, thereby improving the alignment accuracy of the two flat reflectors and enhancing the welding effect.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1 to 4 The example shown is a welding clamping fixture for solar thermal power generation reflectors, comprising:

[0028] The support plate 1 has a welding table 2 fixed on the upper middle part. The welding table 2 has grooves 3 on both the front and rear sides and the left and right sides. Multiple rollers 19 are installed in the grooves 3 at equal intervals. The middle parts of the front and rear sides of the support plate 1 are equipped with first electric push rods 4. The output end of the first electric push rod 4 is connected to a push plate 5. The left and right ends of the lower middle part of the support plate 1 are equipped with second electric push rods 6. The output ends of the two second electric push rods 6 pass through the support plate 1 and are connected to a pressure frame 7.

[0029] Two limiting mechanisms are installed on the front and rear parts of the support plate 1 respectively. The limiting mechanism includes two limiting components 8 and a driving component that drives the two limiting components 8 to move synchronously. The limiting component 8 includes a movable seat 9, and multiple limiting rollers 10 are rotatably installed at equal intervals on the upper side of the movable seat 9.

[0030] The pressure frame 7 is located above the welding table 2. The pressure frame 7 has a welding port 18. The pressure frame 7 presses on two flat reflectors. The welding port 18 exposes the mating part of the flat reflectors, which is convenient for the welding gun to weld.

[0031] Multiple limiting rollers 10 pass through the corresponding grooves 3, and the multiple limiting rollers 10 and multiple rollers 19 are spaced apart.

[0032] Side plates 17 are fixed to the lower left and right edges of the bearing plate 1;

[0033] The drive assembly includes a servo motor 11, a first lead screw 12, and a second lead screw 13. The servo motor 11 is mounted on a side plate 17. The output end of the servo motor 11 passes through the side plate 17 and is connected to the first lead screw 12. The end of the first lead screw 12 away from the servo motor 11 is connected to the second lead screw 13. The end of the second lead screw 13 away from the first lead screw 12 is rotatably connected to the side plate 17. The second lead screw 13 is symmetrically arranged with the first lead screw 12. Nut seats 14 are sleeved on both the first lead screw 12 and the second lead screw 13. The nut seats 14 are connected to the corresponding moving seats 9.

[0034] The servo motor 11 drives the first lead screw 12 and the second lead screw 13 to rotate, thereby causing the nut seats 14 on the first lead screw 12 and the second lead screw 13 to move closer or further away from each other, which in turn causes the two left and right limit components 8 to move closer or further away from each other.

[0035] The lower front and rear sides of the movable seat 9 are fixed with collars 15. The two collars 15, which are symmetrical on the left and right, slide together and nest the limiting rod 16. The two ends of the limiting rod 16 are connected to the two side plates 17 respectively, so that the limiting component 8 moves stably and will not deviate.

[0036] The top surface of the roller 19 is level with the upper side of the welding table 2, so that the reflector moving on the roller 19 can move one side onto the welding table 2, which facilitates the alignment of the two planar reflectors.

[0037] A sliding groove 20 is provided between the two grooves 3 on the left and right sides. The lower end of the push plate 5 is slidably nested in the sliding groove 20, so that the push plate 5 moves stably and can effectively push the reflector.

[0038] In this invention, two planar reflectors are placed at the front and back of the welding table 2. The servo motors 11 of the two limiting mechanisms drive the first lead screw 12 and the second lead screw 13 to rotate, causing the nut seats 14 on the first lead screw 12 and the second lead screw 13 to move closer or further apart. This causes the two left and right limiting components 8 to move closer together, squeezing and limiting the planar reflectors. At the same time, the two first electric push rods 4 push the two planar reflectors through the push plate 5, so that the side of the two planar reflectors that is close to each other moves to the welding table 2 and aligns with each other. Simultaneously, the two second electric push rods 6 work in sync to drive the pressure frame 7 to move down, squeezing the two planar reflectors and preventing the mating part of the two planar reflectors from lifting. This improves the alignment accuracy of the two planar reflectors and improves the welding effect. The welding port 18 on the pressure frame 7 exposes the mating part of the planar reflectors, making it convenient for the welding gun to weld.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
