Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to a positioning tooling for a latch mounting plate in a loader cab. Background Art

[0002] The latch mounting plate is a device for installing the latch, wherein the loader cab latch is a door lock installed on the door panel of the loader cab, and the latch mounting plate is a supporting structure for fixing the latch on the door frame, which is used to ensure the stability and safety of the latch. By using the latch mounting plate, the connection between the latch and the door frame can be ensured to be firm and reliable, providing higher safety and protection performance.

[0003] In the process of fixing the mounting plate, the common installation and fixing method is to fix it with screws. In this process, the common positioning method is to use hand support to maintain stability. There will inevitably be some deviations, and accurate positioning cannot be performed. When deviations occur, the screws are not directly removed and reinstalled. The operation is relatively troublesome, and if the screw holes are too close, it will also affect the stability after fixation. Utility Model Content

[0004] The utility model aims to solve the problems existing in the background technology and proposes a positioning tool for a latch mounting plate of a loader cab.

[0005] The technical solution of the utility model is as follows: a loader cab latch mounting plate positioning tool, comprising a mounting plate body, a positioning plate and an adsorption plate, a lock core hole is opened in the middle position of the mounting plate body, screw holes are opened at the four corners of the mounting plate body, a pair of positioning grooves are opened on the back of the mounting plate body, the positioning plate is fixed on the adsorption plate, and a positioning groove adapted to the adsorption plate is opened on the back of the mounting plate body and located at the opening of the positioning groove.

[0006] Preferably, a piston plate is slidably connected inside the adsorption disk, a pair of limit rods are fixed to the inner wall of the adsorption disk, the limit rods pass through the piston plate and are slidably connected to the piston plate, and a rubber sleeve is fixed to the periphery of the limit rods to ensure that the piston plate can only perform telescopic movement in the adsorption disk.

[0007] Preferably, an airtight pad is fixed at the opening of the adsorption plate to increase the airtightness of the connection between the adsorption plate and the door panel, thereby increasing the stability of the adsorption plate after adsorption.

[0008] Preferably, a threaded sleeve is rotatably connected to the connection between the positioning plate and the adsorption disk, a threaded rod is internally threadedly connected to the threaded sleeve, and the end of the threaded rod is fixed to the piston plate. The rotation of the threaded sleeve can drive the threaded rod and the piston plate to perform telescopic movement.

[0009] Preferably, a rotation groove is opened in the middle position of the front end of the positioning plate, and a rotation rod is rotatably connected in the rotation groove. The rotation rod is fixed to the end of the threaded sleeve. The rotation groove can be used to ensure that the front end of the positioning plate is in a horizontal state and can be better inserted into the positioning groove.

[0010] Preferably, the size of the positioning plate is matched with the size of the positioning slot, and a level is fixed to the front end of the positioning plate. After the positioning plate is fixed, it can be visually observed whether the fixed position is horizontal.

[0011] Compared with the prior art, the utility model has the following beneficial technical effects: the positioning plate is fixed on the loader door panel by adsorption, which can not only position the installation of the mounting plate body and ensure the accuracy of the installation position, but also facilitate position adjustment and make the operation simpler.

[0018] like Figure 1-3 As shown, the utility model proposes a loader cab latch mounting plate positioning tool, including a mounting plate body 1, a positioning plate 23 and an adsorption plate 2, a lock core hole 11 is opened in the middle position of the mounting plate body 1, screw holes 12 are opened at the four corners of the mounting plate body 1, a pair of positioning grooves 14 are opened on the back of the mounting plate body 1, the positioning plate 23 is fixed on the adsorption plate 2, and a positioning groove 14 matched with the adsorption plate 2 is opened on the back of the mounting plate body 1 and located at the opening of the positioning groove 14, the size of the positioning plate 23 is matched with the size of the positioning groove 14, and a spirit level 26 is fixed on the front end of the positioning plate 23.

[0019] A piston plate 21 is slidably connected inside the suction disc 2, and a pair of limiting rods are fixed to the inner side wall of the suction disc 2, the limiting rods pass through the piston plate 21 and are slidably connected to the piston plate 21, a rubber sleeve is fixed to the periphery of the limiting rods, an airtight pad 22 is fixed at the opening of the suction disc 2, a threaded sleeve 27 is rotatably connected at the connection between the positioning plate 23 and the suction disc 2, a threaded rod 28 is threadedly connected to the threaded sleeve 27, and the end of the threaded rod 28 is fixed on the piston plate 21, a rotating groove 24 is provided in the middle position of the front end of the positioning plate 23, a rotating rod 25 is rotatably connected in the rotating groove 24, and the rotating rod 25 is fixed to the end of the threaded sleeve 27, and the rotation of the rotating rod 25 can drive the threaded sleeve 27 to rotate, and at this time, the threaded rod 28 can be used to perform telescopic movement, driving the piston plate 21 to telescope, and when negative pressure is formed in the suction disc 2, the suction disc 2 can be adsorbed and fixed on the door panel.

[0020] In this embodiment, the adsorption plate 2 needs to be adsorbed on the door panel first. During this process, the adsorption plate 2 is closely attached to the specified position of the door panel of the loader cab. The rotation of the rotating rod 25 can drive the threaded sleeve 27 to rotate. At this time, the threaded rod 28 can be used to perform telescopic movement, driving the piston plate 21 to extend and retract, and finally fixed to the door panel by negative pressure adsorption, thereby realizing the fixation of the positioning plate 23. The two positioning plates 23 are fixed to the door panel and maintained at a specified distance. At the same time, the level 26 is used to ensure that the positioning plates 23 are in a horizontal state, and then the mounting plate body is installed.

Finally, when the screws are passed through the screw holes 12 for fixing, there will be no deviation, and accurate positioning can be achieved. Even if there is a deviation in the positioning, the mounting plate body 1 cannot accurately match the positioning plate 23, the rotation of the rotating rod 25 can be used to release the fixation of the suction plate 2, and then reposition it. The position adjustment operation is relatively simple and can be completed by any required locking structure.
