Description

Technical Field

[0001] The utility model relates to the technical field of processing slot wedge braces, in particular to a grinding device for glass fiber reinforced plastic slot wedge braces. Background Art

[0002] Slot wedges are usually used in transformer production to form ventilation and heat dissipation channels in the transformer. Slot wedges are generally called strip-shaped, and their cross-sectional shape is rectangular. The slot wedges are inserted during production and pulled out after completion, leaving a through hole in the transformer. In order to be able to pull out the slot wedges smoothly, the surface of the slot wedges is often required to be smooth, so the surface of the slot wedges needs to be polished before use.

[0003] In the prior art, the grinding of the slot wedge support strips is usually performed by manual grinding with sandpaper. The slot wedge support strips are simply laid flat on the workbench, and there is no corresponding slot wedge support strip fixing and limiting device, which causes the slot wedge support strips to easily move, thereby affecting the grinding quality. On the other hand, during manual grinding, factors such as the friction angle, force and grinding speed between the sandpaper and the slot wedge support strips are only controlled by human operating experience. It is common that the grinding quality is uneven or the release agent is not completely removed. In addition, manual grinding operations are not only labor-intensive and inefficient, but also easily cause operator scratches or the slot wedge support strips to be scrapped. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] A grinding device for a glass fiber reinforced plastic groove wedge support strip, comprising a machine platform 1, a grinding mechanism, a horizontal moving mechanism, a lifting mechanism and a material fixing mechanism;

[0027] The horizontal moving mechanism is installed on the machine table 1 and is used to drive the grinding mechanism to move in the X-axis and Y-axis directions;

[0028] The lifting mechanism is installed on the horizontal moving mechanism and is used to drive the grinding mechanism to lift vertically;

[0029] The grinding mechanism comprises a grinding disc 8 which is horizontally rotatably mounted on the lifting mechanism, the lower surface of the grinding disc 8 is a frosted surface, and the grinding disc 8 is driven to rotate by a first rotating motor 9;

[0030] The material fixing mechanism is installed on the machine table 1 and is located below the grinding disc 8, and includes a material plate 2, on which two parallel clamping strips 3 are slidably installed. The two clamping strips 3 are driven by a driving mechanism to move synchronously and symmetrically. The two clamping strips 3 move synchronously toward each other or move synchronously away from each other. The material plate 2 is fixed with a stop bar 23 located at one end of the two clamping strips 3, and the length direction of the stop bar 23 is perpendicular to the length direction of the clamping strip 3.

[0031] A plurality of FRP wedge profiles of the same specification are placed between two clamping strips 3, and one end of the FRP wedge profile is placed against the retaining strip 23, so that the plurality of FRP wedge profiles remain flush and the end is positioned, and then the driving mechanism drives the two clamping strips 3 to move toward each other synchronously, so that the plurality of FRP wedge profiles are gathered together to form a plane and fixed, and then the lifting mechanism drives the grinding disc 8 to descend to the upper end of the FRP wedge profile, and starts rotational grinding, and drives the grinding disc 8 to move along the length direction of the clamping strip 3 and perpendicular to the length direction of the clamping strip 3 through the horizontal moving mechanism, so that back and forth grinding can be performed on the plane formed by the plurality of FRP wedges. In this embodiment, the thickness of the clamping strip 3 and the retaining strip 23 is less than the thickness of the FRP wedge profile.

[0032] Through the above method, several long-strip fiberglass wedge profiles can be fixed together and the surface can be polished at the same time, and the two clamping strips 3 are driven by the driving mechanism to move toward each other to clamp the several fiberglass wedge profiles for fixation, which is convenient and quick.

[0033] The preferred technical solution is that the driving mechanism includes a rack 4, a driving gear 5 and a second rotating motor 6. The material plate 2 is installed on the machine table 1 through a bracket. There is a gap between the material plate 2 and the machine table 1. A rotating driving gear 5 is provided under the material plate 2. The driving gear 5 is driven to rotate by the second rotating motor 6 installed on the machine table 1, and the position of the driving gear 5 is fixed. The second rotating motor 6 is vertically installed on the machine table 1, and the output shaft of the second rotating motor 6 is arranged upward. The driving gear 5 is fixedly installed on the output shaft of the second rotating motor 6. The driving gear 5 is located at the midpoint of the line connecting the two clamping strips 3. Two racks 4 arranged parallel to the moving direction of the clamping strips 3 are meshed and connected on both sides of the driving gear 5. The two racks 4 are respectively fixedly connected to the two clamping strips 3 through connecting blocks. The material plate 2 is penetrated by a bar-shaped through hole 21 for the connecting block to pass and move.

[0034] The two racks 4 are respectively located on both sides of the driving gear 5 and are fixedly connected to the two clamping strips 3. The length direction of the rack 4 is perpendicular to the length direction of the clamping strip 3. When the second rotating motor 6 drives the driving gear 5 to rotate, the rack 4 meshing with the driving gear 5 moves in a direction perpendicular to the clamping strip 3, and the moving directions of the two racks 4 are opposite, thereby driving the two clamping strips 3 to move synchronously.

[0035] According to a preferred technical solution, the clamping strip 3 is connected to a guide structure, and the guide structure includes a guide groove 22 opened at the upper end of the material plate 2, and the length direction of the guide groove 22 is arranged along the moving direction of the clamping strip 3. A guide slider matching the guide groove 22 is opened at the lower end of the clamping strip 3, and the guide slider is embedded in the guide groove 22.

[0036] According to the preferred technical solution, the grinding disc 8 is detachably mounted on the lifting mechanism, and a rotating mounting plate 7 is mounted on the lifting mechanism. The first rotating motor 9 drives the mounting plate 7 to rotate. The mounting plate 7 is circular in shape, and a rotating shaft is fixedly provided at the center of the upper end of the mounting plate 7. The rotating shaft is rotatably mounted on the lifting mechanism. The grinding disc 8 is detachably connected to the lower end of the mounting plate 7. A plurality of vertically arranged connecting columns 16 are fixedly provided at the upper end of the grinding disc 8. The lower end of the mounting plate 7 has a first jack 17 for the connecting column 16 to be matched and inserted. A threaded hole is extended downwardly from the upper end of the connecting column 16. A mounting hole connected to the threaded hole is vertically provided downwardly on the upper end of the mounting plate 7. A bolt 18 screwed to the threaded hole passes through the mounting hole, thereby locking the grinding disc 8 on the mounting plate 7.

[0037] Through the above method, the grinding disc 8 can be easily replaced.

[0038] According to a preferred technical solution, a plurality of vertical reinforcing columns 19 are fixedly provided on the upper end of the grinding disc 8 , and a second insertion hole 20 is provided at the lower end of the mounting plate 7 for the reinforcing columns 19 to be inserted into. The reinforcing columns 19 are arranged close to the edge of the grinding disc 8 .

[0039] Since the grinding disc 8 and the mounting plate 7 are detachably connected, when the mounting plate 7 drives the grinding disc 8 for grinding, the torque between the mounting plate 7 and the grinding disc 8 acts on the connecting column 16, but since the connecting column 16 is provided with a threaded hole, the structural strength is low. Through the above method, a plurality of reinforcing columns 19 arranged on the edge of the grinding disc 8 are inserted into the mounting plate 7, and the solid reinforcing columns 19 share the torque borne by the connecting column 16, which can greatly improve the connection strength between the mounting plate 7 and the grinding disc 8.

[0040] A preferred technical solution, the horizontal moving mechanism includes two columns 14 respectively arranged on both sides of the material fixing mechanism, the two columns 14 are moved along the length direction of the clamping strip 3 through a first screw mechanism 15 respectively, the upper ends of the two columns 14 are connected by a cross beam, and a support frame 12 is installed on the cross beam, which is moved by a second screw mechanism 13, and the moving direction of the support frame 12 is perpendicular to the length direction of the clamping strip 3, and the lifting mechanism is installed on the support frame 12.

[0041] The first screw mechanism 15 and the second screw mechanism adopt the existing technology. The first screw mechanism 15 drives the column 14 and the crossbeam to move along the length direction of the clamping strip 3, and the second screw drives the lifting mechanism to move along the length direction perpendicular to the clamping strip 3, thereby driving the grinding disc 8 to move.

[0042] The preferred technical solution is that the lifting mechanism includes a lifting cylinder 11 vertically installed on the horizontal moving mechanism, the lifting cylinder 11 is fixed on the support frame 12, the output shaft of the lifting cylinder 11 is arranged downward and fixedly connected to the mounting frame 10, the grinding disc 8 is rotatably installed on the mounting frame 10, the rotating shaft is rotatably connected to the mounting frame 10, the first rotating motor 9 is installed on the mounting frame 10, and the rotating shaft is driven to rotate by the first rotating motor 9.
