Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to a positioning tooling for a middle gantry. Background Technique

[0002] The forklift mast is the working device of the forklift, that is, the mechanism for lifting goods. It consists of an inner mast, an outer mast, a fork carriage, forks, sprockets, chains, a lifting cylinder, a tilting cylinder, etc. During the production process of the forklift mast, it is necessary to assemble a three-section mast or a two-section mast. When the current workshop produces the middle mast assembly, the method of scribing is used to assemble the oil cylinder seat assembly on the platform, and then it is taken to the mast for assembly. However, this assembly method has two serious defects: (1) Low efficiency: Because the scribing method is used for assembly, it is necessary to scribe and assemble the position dimensions of each part one by one, which is time-consuming and laborious; (2) Poor accuracy: Because the oil cylinder seat assembly is mainly spatial dimensions, and a tape measure is used for scribing, the accuracy is generally about 1 mm, and it is difficult to meet the dimensional requirements of the drawing.

[0003] The existing gantry positioning tooling on the market generally directly positions and welds the positioning device, so that it can effectively limit the forklift workpiece at a fixed position, avoiding exceeding the maximum moving range during use, resulting in the separation of parts and causing unnecessary losses and even potential safety hazards. However, in the actual use process, according to the different processing methods and the installation positions of the processing devices, it is necessary to finely adjust the workpiece after positioning. Therefore, we propose a positioning tooling for the middle gantry. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a positioning tooling for a middle gantry, which solves the problem that in the actual use process, according to the different processing methods and the installation positions of the processing devices, it is necessary to finely adjust the workpiece after positioning.

[0005] The above technical object of the utility model is achieved through the following technical solutions:

[0006] The positioning tooling for the middle gantry includes a positioning square pipe. Two side top plates are fixedly installed on the outer wall surface of the positioning square pipe. Fixed grooves are opened on the top surfaces of the side top plates. Positioning plates are fixedly installed inside the fixed grooves opened on the top surfaces of the side top plates. The positioning square pipe, the side top plates, and the positioning plates are welded together in a positioned manner to form Tooling A, and Tooling A is placed on the upper end surface of the middle gantry channel steel.

[0007] Preferably, a cylinder head seat is fixedly installed on one side of the side top plate, and a sprocket shaft backing plate is fixedly installed on one side of the cylinder head seat.

[0008] Preferably, a first threaded hole is provided on one side of the side top plate, and a cylinder head seat lateral positioning bolt is threadedly connected inside the first threaded hole provided on one side of the side top plate.

[0009] Preferably, a second threaded hole is provided on one side of the side top plate, and a tooling lateral positioning bolt is threadedly connected inside the second threaded hole provided on one side of the side top plate.

[0010] Preferably, a middle gantry is provided on the bottom surface of the positioning square tube. The positioning square tube and the middle gantry are connected by the tooling lateral positioning bolt, and a tooling longitudinal positioning plate is fixedly installed on one side of the positioning plate.

[0011] Preferably, a connecting square tube is fixedly installed on the top surface of the middle gantry, and two tooling longitudinal limiting plates are fixedly installed on one side of the positioning square tube.

[0012] In summary, the present utility model mainly has the following beneficial effects:

[0013] By providing a positioning square tube, through the welded design of the positioning square tube, the side top plate and the positioning plate, on the premise of ensuring the overall integrity of the device, directly placing it on the upper end surface of the middle gantry channel steel can make the positioning part more flexible. With the cooperation of adjustment elements, the specific position of the positioning can be adjusted manually by workers, increasing the accuracy of device processing;

[0014] Through the setting of the tooling longitudinal limiting plate, the longitudinal position of the connecting square tube can be limited through its fixed design, avoiding that during the longitudinal movement of the device, it exceeds the limited range, resulting in the device being unable to be positioned normally.

The positioning square tube 1, the side top plate 2 and the positioning plate 3 are positioned and welded together to form tooling A. The tooling A is placed on the upper end surface of the middle gantry channel steel. Through the welded design of the positioning square tube 1, the side top plate 2 and the positioning plate 3, the positioned part can be more flexible when placed on the upper end surface of the middle gantry channel steel. With the cooperation of the adjusting element, the specific position of the positioning can be adjusted manually by the operator, increasing the accuracy of the device processing;

[0020] On one side of the side top plate 2, a cylinder head seat 10 is fixedly installed. On one side of the cylinder head seat 10, a sprocket shaft backing plate 9 is fixedly installed. Through the design of the sprocket shaft backing plate 9 and the cylinder head seat 10, it is convenient for the device to be effectively connected to an external workpiece. After the shaft backing plate 9 and the cylinder head seat 10 are positioned by the tooling A, the parts can be directly installed in place, which is more convenient and faster than the traditional installation process. On one side of the side top plate 2, a first threaded hole is provided. A cylinder head seat lateral positioning bolt 4 is threadedly connected inside the first threaded hole provided on one side of the side top plate 2. Through the design of the cylinder head seat lateral positioning bolt 4, the lateral limit of the cylinder head seat 10 can be adjusted by tightening and loosening the cylinder head seat lateral positioning bolt 4, so as to avoid the problem that the deviation is too large to be normally connected when the device body is connected to an external workpiece. On one side of the side top plate 2, a second threaded hole is provided. A tooling lateral positioning bolt 5 is threadedly connected inside the second threaded hole provided on one side of the side top plate 2. Through the design of the bolt 5, the lateral limit of the tooling A is adjusted, so that after the device positions and installs the workpiece, the position of the tooling A can be finely adjusted by tightening or loosening the bolt 5, and the workpiece can be positioned more accurately during processing, increasing the processing efficiency. On the bottom surface of the positioning square tube 1, a middle gantry 11 is provided. Through the design of the middle gantry 11, it can be used as a connecting device between the positioning device and the vehicle body. After being adjusted to the appropriate position, it can normally complete the limiting function. The positioning square tube 1 and the middle gantry 11 are connected by the tooling lateral positioning bolt 5. On one side of the positioning plate 3, a tooling longitudinal positioning plate 6 is fixedly installed. On the top surface of the middle gantry 11, a connecting square tube 8 is fixedly installed. On one side of the positioning square tube 1, two tooling longitudinal limiting plates 7 are fixedly installed. Through the setting of the tooling longitudinal limiting plates 7, the longitudinal direction of the connecting square tube 8 can be limited by its fixed design, so as to avoid the device moving longitudinally beyond the limited range and causing the device to be unable to be normally positioned.
