Description

Technical Field

[0001] This utility model belongs to the field of forklift parts processing technology, and in particular relates to a positioning fixture for welding the inner plate of the front anti-collision beam of a forklift. Background Technology

[0002] Forklifts are industrial handling vehicles, referring to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. For example, when handling paper rolls or molten iron, forklifts need to be equipped with attachments to perform special functions. The inner plate of the forklift's front anti-collision beam is used to protect the front of the forklift from collisions, and welding is required during the actual processing.

[0003] When welding the inner plate of the forklift front bumper beam, it is necessary to position it to prevent displacement of the plate during the welding process, thereby improving the welding accuracy. Some positioning structures use bolt fastening, which requires rotating the bolts before and after welding, which is inconvenient. Therefore, a positioning fixture for welding the inner plate of the forklift front bumper beam is needed, which can quickly position the inner plate on the welding table, thereby reducing time consumption and improving the efficiency of the inner plate welding process. Utility Model Content

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A positioning fixture for welding the inner plate of the front anti-collision beam of a forklift includes a welding table: a rotating rod is rotatably connected to the surface of the welding table via a rotating shaft, a pressure block is provided at the bottom of the rotating rod, a bolt rod is installed between the rotating rod and the pressure block, an L-shaped plate is welded to the surface of the welding table, a motor is fixedly installed on the surface of the L-shaped plate by bolts, the output shaft of the motor passes through the L-shaped plate and is fixedly connected to a gear through a flange, a sleeve block is fixedly installed on the inner wall of the L-shaped plate, a rack is slidably connected to the inner wall of the sleeve block, a rectangular groove is opened on the surface of the rotating rod, and an L-shaped rod is fixedly connected to the top of the rack.

[0006] Preferably, the end of the L-shaped rod extends into the inner cavity of the rectangular groove.

[0007] Preferably, the surface of the L-shaped rod is rotatably connected to a rotating sleeve, and the surface of the rotating sleeve is in contact with the inner wall of the rectangular groove.

[0008] Preferably, a pressure sensor and a controller are fixedly mounted on the surface of the welding station by bolts, and the motor and the pressure sensor are electrically connected to the controller by wires.

[0012] 1. This utility model uses the upward movement of the rack in the vertical direction to drive the L-shaped rod to move, so that the L-shaped rod moves the inner wall of the rectangular groove and drives the rotating rod to rotate. Then the rotating rod drives the pressure block to clamp and fix the inner plate on the top of the welding table, which can achieve quick positioning of the inner plate on the welding table, thereby reducing time consumption and improving the efficiency of the inner plate welding process.

[0013] 2. By using a rotating sleeve, this utility model creates a gap between the L-shaped rod and the inner wall of the rectangular groove, thus avoiding excessive wear when the two are in direct contact.

[0014] 3. This utility model, through the combined use of a pressure sensor and a controller, can compress the pressure sensor when the inner plate is placed on top of the welding table, so that the pressure sensor controls the motor to start through the controller, thus achieving self-starting and high automation efficiency.

[0015] 4. This utility model uses the combination of the insertion rod and the insertion hole to horizontally limit the connection between the rotating rod and the pressure block, thus preventing the two from sliding relative to each other in the horizontal direction. Attached Figure Description

[0027] Example 2:

[0028] Figure 1-5This invention illustrates a positioning fixture for welding the inner plate of a forklift front bumper beam according to an embodiment of the present invention. It includes a welding table 1; a rotating rod 2 is rotatably connected to the surface of the welding table 1 via a rotating shaft; a pressure block 3 is provided at the bottom of the rotating rod 2; a bolt rod 4 is installed between the rotating rod 2 and the pressure block 3; an L-shaped plate 6 is welded to the surface of the welding table 1; a motor 7 is fixedly mounted on the surface of the L-shaped plate 6 via bolts; the output shaft of the motor 7 passes through the L-shaped plate 6 and is fixedly connected to a gear 8 via a flange; a sleeve block 9 is fixedly mounted on the inner wall of the L-shaped plate 6. The inner wall of the device is slidably connected to a rack 10. A rectangular groove 11 is opened on the surface of the rotating rod 2. An L-shaped rod 12 is fixedly connected to the top of the rack 10. An insert rod 5 is integrally formed on the top of the pressure block 3. The end of the insert rod 5 extends through to the top of the rotating rod 2. An insertion hole 16 that matches the insert rod 5 is opened on the top of the rotating rod 2.

At this time, the pressure sensor 14 senses the pressure and transmits the signal to the controller 15, causing the controller 15 to control the motor 7 to start. Then, the motor 7 drives the rack 10 to move through the gear 8, causing the rack 10 to move upward in the inner wall of the sleeve block 9, driving the L-shaped rod 12 to move. Then, the L-shaped rod 12 moves the inner wall of the rectangular groove 11 and drives the rotating rod 2 to rotate. In turn, the rotating rod 2 drives the pressure block 3 to clamp and fix the inner plate on top of the welding table 1, realizing quick positioning of the inner plate on the welding table, thereby reducing time consumption and improving the efficiency of the inner plate welding process.

[0030] In summary, the positioning fixture for welding the inner plate of the forklift front anti-collision beam uses the upward movement of the rack 10 in the vertical direction to move the L-shaped rod 12, which in turn moves the inner wall of the rectangular groove 11 and drives the rotating rod 2 to rotate. The rotating rod 2 then drives the pressure block 3 to clamp and fix the inner plate on the top of the welding table 1, thus achieving quick positioning of the inner plate on the welding table, reducing time consumption, and improving the efficiency of the inner plate welding process.
