When working at the excavation end, the driver also needs to open the window. The sliding window of the excavator cab is usually arranged as a whole wall in front of or behind the cab. Figure 1 The sliding window connecting plate shown controls the opening angle of the sliding window. The sliding window connecting plate includes a sliding window mounting plate 1 and a sliding window connecting rod 2 on both sides. The sliding window connecting plate not only fixes the sliding window, but also ensures the consistency of the left and right opening angles when the sliding window is opened and closed.
[0004] Since the backhoe loader is large in size, its sliding window is large in size and heavy in weight. The traditional welding method using dimension marking cannot accurately ensure the position of the two sliding window mounting plates 1. When opened, the sliding window has different left and right angles and is prone to flipping, which may cause damage to the sliding window or even accidental injury to workers. Utility Model Content
[0005] The technical problem to be solved by the utility model is how to make the left and right opening angles of the sliding window consistent when the sliding window is opened and closed.
[0006] In order to solve the above technical problems, the technical solution of the utility model is to provide a welding device for sliding window connecting plates in the cab of an excavator loader, including a sliding window mounting plate and a sliding window connecting rod, wherein two sliding window mounting plates are provided and are placed parallel to each other, the sliding window connecting rod is connected between the two sliding window mounting plates and is located at one end of the sliding window mounting plates, and also includes a base, a sliding window mounting plate positioning assembly and a sliding window connecting rod positioning assembly, the sliding window mounting plate positioning assembly is provided with two groups, which are symmetrically arranged on the base, and the sliding window connecting rod positioning assembly is arranged on the base and is located between the two groups of sliding window mounting plate positioning assemblies.
[0007] Optionally, the sliding window mounting plate positioning assembly includes a front positioning seat and a rear positioning seat, the inner sides of the front positioning seat and the rear positioning seat are located in the same vertical plane, and both sides are provided with penetrating positioning holes, and the positioning holes are provided with positioning pins.
[0008] Optionally, the sliding window connecting rod positioning assembly includes a height limiting seat and a front and rear limiting seat, and the height limiting seat and the front and rear limiting seat are alternately arranged and are both located between the rear positioning seats.
[0009] Optionally, a mounting hole corresponding to the positioning hole is provided on the sliding window mounting plate, and the sliding window mounting plate is installed on the front positioning seat and the rear positioning seat on the same side through positioning pins. The sliding window connecting rod is placed on the height limit seat, and one side is close to the front and rear limit seats.
[0010] Optionally, the front positioning seat and the rear positioning seat are connected to the sliding window mounting plate by a through-axis positioning method, and the sliding window connecting rod is in transitional contact with the front and rear limit seats by a rounded corner.
[0011] Optionally, the tolerance of the locating pins on the front locating seat and the rear locating seat is -0.2 to -0.1 mm.
[0012] In summary, the utility model arranges the front positioning seat and the rear positioning seat so that the sliding window mounting plates are placed parallel to each other, and uses the height limit seat and the front and rear limit seats to accurately install the sliding window connecting rod, so that the angles of the two ends of the sliding window are consistent when the sliding window is opened, avoiding tilting damage.
