Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, and in particular to a tooling for simultaneously testing the inner hole and bolt hole dimensions of excavator chain links. Background Technology

[0002] With the development of the social economy and the large-scale investment in infrastructure construction, excavators have been used more and more widely. Among them, the chain of the excavator, as one of the important components, mainly plays the role of driving the excavator forward or backward.

[0003] For the current excavator chain link assembly, it is mainly composed of left and right chain links, and the size and position requirements between the pin sleeve hole and the bolt hole after the two chain link assemblies are assembled are relatively qualified.

[0004] Traditional inspection tools require separate inspection of the position and diameter of the excavator chain link pin bushing hole and bolt hole, which takes a lot of time and is not conducive to improving work efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tooling for simultaneously detecting the inner hole and bolt hole dimensions of excavator chain links. This overcomes the deficiencies of existing technologies and effectively solves the problem that existing technologies require separate detection of the position and diameter of the excavator chain link pin bushing hole and bolt hole, which results in excessive detection time and hinders work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tooling for simultaneously detecting the inner hole and bolt hole dimensions of excavator chain links includes a U-shaped frame. Two-way lead screws are rotatably connected to the inner walls of both ends of the U-shaped frame, and movable blocks are screwed to both ends of the rod walls of the two-way lead screws. A fixed rod is fixed to the top of the movable blocks. Positioning mechanisms are respectively provided at both ends of one outer wall of the U-shaped frame. The positioning mechanism includes a movable plate, sliders fixed to the outer walls of both sides of the movable plate, a handle screw screwed to the top of the movable plate, and a collar sleeved and fixed to the rod wall of the handle screw screw.

[0008] A standard excavator chain link is placed inside a U-shaped frame. By rotating the double-acting screw, the positions of the two movable blocks and the fixed rod are adjusted so that the positions of the two fixed rods match the bolt holes of the excavator chain link. Then, the positions of the two positioning mechanisms are adjusted, and the positioning mechanisms and the inner holes of the excavator chain link are inserted through the first and second positioning rods. This determines the specifications of a qualified excavator chain link. The excavator chain link to be tested is placed inside the U-shaped frame. Those that can form an insertion fit with the fixed rods and the first and second positioning rods are qualified products.

[0009] Preferably, the bottom of the U-shaped frame is provided with an installation groove, and the two ends of the bidirectional lead screw are rotatably connected to the inner walls of the two ends of the installation groove.

[0010] The bidirectional lead screw is rotated and installed using the mounting slot.

[0011] Preferably, an installation opening is provided on one outer wall of the U-shaped frame, and a sliding groove is provided on the top inner wall of the installation opening.

[0012] The positioning mechanism is installed through the designated mounting port and slide groove.

[0013] Preferably, the movable plate and the slide groove form a sliding fit, and the slider and the top inner wall of the mounting port form a sliding fit.

[0014] The movable plate slides along the groove inside the mounting opening via a slider.

[0015] Preferably, the bottom outer diameter of the handle screw is smaller than the width of the groove, and the bottom of the collar is engraved with protective threads.

[0016] Turn the handle screw to press the collar down onto the top of the slide groove, thereby fixing the position of the positioning mechanism.

[0017] Preferably, each of the two movable plates has a positioning hole on one side of its outer wall, and a first positioning rod and a second positioning rod are respectively inserted into the two positioning holes.

[0018] The position of the excavator chain link's inner hole is checked using the first and second positioning rods.

[0019] The beneficial effects of this utility model are as follows:

[0020] By placing a standard excavator chain link within a U-shaped frame and adjusting the positions of two fixing rods to align with the bolt holes of the excavator chain link, and then adjusting the positions of two positioning mechanisms, the first and second positioning rods are used to insert the positioning mechanisms into the inner holes of the excavator chain link. This process determines the specifications of a qualified excavator chain link. Excavator chain links to be tested are placed in the U-shaped frame; those that can form an insert fit with the fixing rods and the first and second positioning rods are considered qualified products. This effectively solves the problem of existing technologies that require separate testing of the position and diameter of the excavator chain link pin sleeve holes and bolt holes, resulting in time-consuming testing and hindering work efficiency.

[0029] The bottom outer diameter of the handle screw 12 is smaller than the width of the slide groove 6. The bottom of the collar 13 is engraved with protective threads. Rotating the handle screw 12 causes the collar 13 to press down on the top of the slide groove 6, thereby fixing the position of the positioning mechanism 7.

By rotating the double-acting screw 2, the positions of the two movable blocks 3 and the fixed rod 4 are adjusted so that the positions of the two fixed rods 4 match the bolt holes of the excavator chain link. Then, the positions of the two positioning mechanisms 7 are adjusted, and the positioning mechanisms 7 and the inner holes of the excavator chain link are inserted through the first positioning rod 8 and the second positioning rod 9. This determines the specifications of a qualified excavator chain link. The excavator chain link to be tested is placed inside the U-shaped frame 1. Those that can form an insertion fit with the fixed rod 4 and the first positioning rod 8 and the second positioning rod 9 are qualified products.
