Description

Technical Field

[0001] The present application relates to the field of welding positioning devices, and in particular to a welding positioning tool for a fallen leaf collecting roller. Background Art

[0002] The fallen leaf collection device includes a handle and a collecting roller. The collecting roller is rotatably connected to the handle. The collecting roller includes a roller and multiple spikes. The spikes are made of metal sheets and are welded and fixed to the roller. By rotating the roller connected to the handle, the user holds the handle and rolls it on the ground, which can make the spikes pierce the scattered leaves on the grass, making it convenient for the user to recycle and dispose of the fallen leaves.

[0003] The production of related collecting rollers requires users to weld and fix the spikes on the roller. The users hold the spikes and welding gun respectively so that the spikes can be arranged at intervals along the axial and circumferential directions of the roller, thereby evenly setting multiple spikes on the roller.

[0004] The above-mentioned related technical solutions have the following defects: during the welding process, it is difficult for the user to determine the installation position of the spikes on the roller. When there are many spikes installed on the collecting roller, the spikes are easily scattered on the roller, resulting in poor production quality of the collecting roller. Utility Model Content

[0005] In order to improve the production quality of the collecting roller, the present application provides a welding positioning tool for the fallen leaf collecting roller.

[0006] The present application provides a welding positioning tool for a fallen leaf collecting roller, which adopts the following technical solution:

[0007] A welding positioning tool for a fallen leaf collecting roller includes a base plate, a bracket, a positioning plate and a connecting rod. Two brackets are provided, and the brackets are installed on the base plate. The brackets are used to be rotatably connected to the end of the roller. One end of the connecting rod is rotatably connected to the base plate, and the other end is fixedly connected to the positioning plate. The positioning plate is used to fit on the surface of the roller. A plurality of positioning grooves are provided on the positioning plate, and the positioning grooves are spaced apart along the arrangement direction of the two brackets.

[0008] By adopting the above technical solution, by arranging a bracket on the bottom plate, the two ends of the roller can be respectively installed on the two brackets, so that the roller can be horizontally set on the bracket and rotated, and by rotating the connecting rod on the bottom plate, the connecting rod can drive the positioning plate to rotate. When the roller is installed on the bracket, the user can rotate the positioning plate and fit it on the roller. At this time, the user can insert the spikes into the positioning groove of the positioning plate and perform welding work. After the user installs a row of spikes on the roller, the roller position can be adjusted by rotating the roller, which makes it convenient for the user to continue to install the spikes. By setting the spikes in the positioning grooves, the accuracy of the spike installation position can be improved, and the production quality of the collecting roller can be improved.

[0009] Optionally, a groove is provided on the top of the bracket, and the groove is a semicircular groove.

[0010] By adopting the above technical solution, a groove is provided on the bracket so that the end shaft of the roller can be stuck in the groove, which makes it convenient for users to install the roller on the bracket and improves the efficiency of installing the roller.

[0011] Optionally, connecting rods are provided on both sides of the positioning plate, and the distance between the connecting rods is greater than the distance between the two brackets.

[0012] By adopting the above technical solution, by arranging connecting rods on both sides of the positioning plate, the positioning accuracy of the positioning plate can be improved, thereby reducing the probability of the positioning plate being offset from the roller position. By arranging the two connecting rods outside the bracket, when the user moves the connecting rods, the probability of the sharp thorns scratching the fingers can be reduced.

[0013] Optionally, the number of the positioning plates is two, and the two positioning plates are rotatably connected to both sides of the bracket respectively.

[0014] By adopting the above technical solution, two positioning plates are set on the bottom plate, so that the two positioning plates can be respectively attached to the surface of the collecting roller, further reducing the probability of the collecting roller rotating on the bracket and improving the position accuracy of the spikes installed on the roller.

[0015] Optionally, the positioning groove is opened on the upper side of the positioning plate.

[0016] By adopting the above technical solution, by opening the positioning groove above the positioning plate, when the user connects the spike to be installed to the positioning groove, the upper part of the spike is exposed from the positioning groove, which makes it convenient for the user to perform the spike welding work. After the user welds a row of spikes on the roller, by rotating the collecting roller, the installed spikes can be stuck on the positioning plate on the other side, and the user can continue to install the spikes on one side of the positioning plate, which makes it convenient for the user to position.

[0017] Optionally, a plurality of clearance grooves are provided on one of the positioning plates, and the clearance grooves are provided at intervals along the arrangement direction of the positioning grooves, and the positions of the clearance grooves correspond to the positions of the positioning grooves one by one.

[0018] By adopting the above technical solution, a plurality of clearance grooves are opened on the positioning plate so that the clearance grooves can be inserted into the spikes. After the user installs multiple rows of spikes on the roller, the positioning plate can continue to fit on the surface of the roller after rotating the roller. The two rows of spikes are respectively stuck in the positioning grooves and the clearance grooves, which can improve the connection stability between the roller and the positioning plate, reduce the probability of the roller rotating on the bracket, and improve the accuracy of installing the spikes on the roller.

[0019] Optionally, a friction strip is installed on the surface of the positioning plate, and the friction strip is made of a rubber material with a rough surface.

[0020] By adopting the above technical solution, by installing a friction strip on the surface of the positioning plate, the friction strip can be fitted on the surface of the roller, thereby increasing the friction between the roller and the positioning plate. When the positioning plate abuts against the surface of the roller, the probability of the roller rotating can be reduced.

[0021] Optionally, the bottom of the base plate is rotatably connected to a rotating base.

[0022] By adopting the above technical solution, by setting a rotating base under the bottom plate, the user can rotate the bottom plate after setting the bottom plate on the table, thereby rotating the collecting roller on the bracket, making it convenient for the user to adjust the angle of the roller and perform welding work.

[0023] In summary, the beneficial technical effects of this application are:

[0024] 1. By arranging brackets on the bottom plate, the two ends of the roller can be respectively installed on the two brackets, so that the roller can be horizontally arranged on the brackets and rotated. By rotating the connecting rod on the bottom plate, the connecting rod can drive the positioning plate to rotate. After the roller is installed on the bracket, the user can rotate the positioning plate and fit it on the roller. At this time, the user can insert the spikes into the positioning grooves of the positioning plate and perform welding work. After the user installs a row of spikes on the roller, the roller position can be adjusted by rotating the roller, which makes it convenient for the user to continue to install the spikes. By arranging the spikes in the positioning grooves, the accuracy of the spike installation position can be improved, thereby improving the production quality of the collecting roller;

[0025] 2. By opening the positioning groove above the positioning plate, when the user clamps the spike to be installed on the positioning groove, the upper part of the spike is exposed from the positioning groove, which makes it easier for the user to weld the spike. After the user welds a row of spikes on the roller, the user can rotate the collecting roller to make the installed spikes clamp on the positioning plate on the other side, and the user can continue to install the spikes on one side of the positioning plate, which makes it easier for the user to position the spikes.

[0026] 3. By opening multiple clearance grooves on the positioning plate, the clearance grooves can be used for the insertion of spikes. After the user installs multiple rows of spikes on the roller, the positioning plate can continue to fit on the roller surface after rotating the roller. The two rows of spikes are respectively stuck in the positioning grooves and the clearance grooves, which can improve the connection stability between the roller and the positioning plate, reduce the probability of the roller rotating on the bracket, and improve the accuracy of installing spikes on the roller.

[0031] The present application is further described in detail below with reference to the accompanying drawings.

[0032] The embodiment of the present application discloses a welding positioning tool for a fallen leaf collecting roller, referring to Figure 1 , including a base plate 1, a bracket 2, a positioning plate 3 and a connecting rod 4. The base plate 1 is arranged horizontally, and two brackets 2 are provided. The two brackets 2 are fixed on the base plate 1. The two ends of the collecting roller 5 are respectively rotatably connected to the two brackets 2. One end of the connecting rod 4 is rotatably connected to the base plate 1, and the other end is fixed to the positioning plate 3. The user first installs the roller 51 on the bracket 2, and then rotates the positioning plate 3 so that the positioning plate 3 can abut against the surface of the roller 51. The positioning plate 3 is provided with a plurality of positioning grooves 31. The positions of the positioning grooves 31 are equidistantly spaced along the length direction of the roller 51. The user can place a plurality of spikes 52 in the positioning grooves 31 in sequence and abut against the surface of the roller 51, so that the user can conveniently weld the spikes 52 on the roller 51 so that the spikes 52 are evenly arranged on the surface of the roller 51.

[0033] Reference Figure 1 The bracket 2 is made of sheet metal and has a semicircular groove 21 on its top. A rotating shaft is coaxially connected to the end of the roller 51, and the rotating shaft can be clamped into the groove 21. The user clamps the rotating shafts at both ends of the roller 51 onto the two brackets 2, respectively, so that the roller 51 is horizontally placed on the brackets 2 and suspended in the air. After welding a row of spikes 52 on the roller 51, the user can rotate the roller 51 and continue welding spikes 52.

[0034] Reference Figure 1 The positioning plate 3 is a long strip structure, with connecting rods 4 connected to both sides of the positioning plate 3. The length of the positioning plate 3 is greater than the distance between the two brackets 2. The user can move the connecting rod 4 outside the roller 51, thereby reducing the chance of the user's fingers being scratched by the sharp thorns 52 when moving the connecting rod 4.

[0035] Reference Figure 1Two positioning plates 3 are provided on the bottom plate 1, and both ends of each positioning plate 3 are connected to a connecting rod 4. The two positioning plates 3 are respectively located on both sides of the bracket 2. When the roller 51 is placed on the bracket 2, the two positioning plates 3 can rotate and fit on the surface of the roller 51. The positioning groove 31 is opened on the upper side of the positioning plate 3. After the user welds a row of spikes 52 on the roller 51, the welded row of spikes 52 can be clamped on the positioning groove 31 of the other positioning plate 3 by rotating the roller 51. At this time, the collecting roller 5 is clamped on the positioning plate 3 and remains fixed, and the user can continue to weld spikes 52 in rows on the surface of the roller 51.

[0036] Reference Figure 1 A positioning plate 3 is provided with multiple clearance grooves 32, which are located in the middle of the positioning plate 3 and correspond one-to-one with the positioning grooves 31. When a large number of spikes 52 are welded to the roller 51, the welded spikes 52 press against the positioning plate 3, making it difficult for the positioning plate 3 to fit onto the surface of the roller 51. By providing the clearance grooves 32 on the positioning plate 3, the welded spikes 52 can be inserted into the clearance grooves 32, allowing the positioning plate 3 to fit tightly onto the roller 51 and secure it.

[0037] In other embodiments, reference Figure 2 A rotating base 11 is provided at the bottom of the base plate 1, and the rotating base 11 is rotatably connected to the base plate 1. The user places the rotating base 11 on the workbench and can rotate the base plate 1 during welding, thereby facilitating the user to adjust the position of the roller 51 and weld around the spikes 52, thereby improving work efficiency.

[0038] Reference Figure 3 The positioning plate 3 is provided with a friction strip 33 on its surface. The friction strip 33 is bonded to the positioning plate 3. When the positioning plate 3 is in contact with the roller 51, the friction strip 33 abuts against the surface of the roller 51. The friction strip 33 can be made of a rubber material with a rough surface. The friction strip 33 is used to increase the friction between the positioning plate 3 and the roller 51, further reducing the probability of the roller 51 rotating relative to the positioning plate 3 and shifting its position.

[0039] The implementation principle of the embodiment of the present application is: by arranging a bracket 2 on the base plate 1, the roller 51 can be horizontally installed on the bracket 2, and by rotating the connecting rod 4 on the base plate 1, the positioning plate 3 can be rotated through the connecting rod 4 and fitted on the roller 51. The user can arrange the spikes 52 in the positioning grooves 31 in sequence and weld them, so that the spikes 52 can be evenly arranged on the roller 51.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
