[0023] Specific embodiments of the present utility model: The frame positioning combination device described includes a processing frame 1, and front positioning seats 2 and rear positioning seats 3 for positioning the ends of the excavator frame are respectively arranged at both ends of the processing frame 1;

[0024] As the inventive point of the present utility model,

[0025] A hole alignment positioning component 4 matching the workpiece holes of the excavator frame and a horizontal locking component 5 for limiting the side wall of the excavator frame are arranged between the front positioning seat 2 and the rear positioning seat 3, and the horizontal locking component 5 is arranged on both sides of the hole alignment positioning component 4;

[0026] Preferably, the horizontal locking component 5 includes a locking seat 51 and a positioning baffle 52. The locking seat 51 and the positioning baffle 52 are relatively fixedly arranged on both sides of the processing frame 1. A locking rod 511 is arranged on the locking seat 51. The locking rods 511 are symmetrically arranged on both side walls of the locking seat 51 and are hinged to the locking seat 51. A support frame 512 for supporting the locking rod 511 is arranged on the locking seat 51.

[0027] With this structure, the horizontal locking component preliminarily positions and limits the front and middle parts of the excavator frame in a surface-contact manner through the relatively arranged locking seats 51 and positioning baffles 52, increasing the contact area, preventing the excavator frame from shaking horizontally during subsequent processing, and improving the processing stability.

[0028] The hole alignment positioning component 4 includes a hole alignment structure for perforating and positioning with the workpiece holes of the excavator frame. The hole alignment structure includes a first positioning frame 41 and a second positioning frame 42. The first positioning frame 41 and the second positioning frame 42 have different heights, and the first positioning frame 41 is higher than the second positioning frame 42. The first positioning frame 41 and the second positioning frame 42 are symmetrically arranged on both sides of the processing frame 1. A first hole alignment pin seat 43 is fixedly provided at the upper end of the first positioning frame 41, and a U-shaped groove for placing the hole alignment pin is formed in the inner wall of the first hole alignment pin seat 43.

[0029] Second hole alignment pin seats 44 are provided on the upper end surfaces of the first hole alignment pin seat 43 and the second positioning frame 42. A hole alignment pin is passed through between the relatively arranged first hole alignment pin seat 43 and the second hole alignment pin seat 44.

[0030] Both ends of the hole alignment pin are clamped with the second hole alignment pin seat 44. Above the second hole alignment pin seat 44, there is a clamping plate 441 that rotates through a hinge for clamping the hole alignment pin. One end of the clamping plate 441 is hinged to the second hole alignment pin seat 44 through a rotating shaft, and the other end is fastened to the second hole alignment pin seat 44 through a fastening bolt 443.

[0031] Grooves 442 that communicate with each other are formed on the side walls of the second hole alignment pin seat 44 and the clamping plate 441. The grooves 442 penetrate through the clamping plate 441. The fastening bolt 443 is arranged in the grooves 442. One end of the fastening bolt 443 is hinged to the second hole alignment pin seat 44, and the other end extends to the outside of the clamping plate 441 and is fastened through a nut. By rotating and loosening the nut, and sequentially rotating the fastening bolt 443 and the clamping plate 441, the hole alignment pin can be taken out.

[0032] On the side walls of the symmetrically arranged first positioning frame 41 and second positioning frame 42, there are laterally supporting rods 45 with a preset number that are connected by threads and telescopically clamp the side walls of the excavator frame in the horizontal direction. The laterally supporting rods 45 respectively pass through the side walls of the first positioning frame 41 and the second positioning frame 42, and the side walls of the excavator frame can be clamped in the horizontal direction by rotating the laterally supporting rods 45.

[0033] With this structure, the hole positioning component 4 can simultaneously position multiple workpiece holes of the excavator frame by setting a hole alignment structure for perforating and positioning the holes of the excavator frame workpiece and a lateral strut 45 for clamping the side wall of the excavator frame. The two cooperate with each other. Moreover, by clamping the side wall of the excavator frame with the lateral strut 45, since the first positioning frame 41 and the second positioning frame 42 have different heights, and the heights of the lateral struts in the first positioning frame 41 and the second positioning frame 42 are also different, the side wall of the excavator frame can be clamped at different points in the vertical direction by rotating the lateral strut 45, which can prevent the excavator frame from shaking in the vertical direction during the machining process.

[0034] Preferably, a preset number of support seats 6 for supporting the excavator frame are arranged along the central axis of the processing frame 1.

[0035] It should be noted that the present invention is a frame positioning combination device. During specific operation,

[0036] An operator uses a hoisting tool to place the two ends of the excavator frame on the processing frame 1 respectively. The front positioning seat 2 and the rear positioning seat 3 respectively position the front end and the rear end of the excavator frame, and the bottom of the excavator frame is supported by the support seat 6; the first hole alignment pin seat 43 and the second hole alignment pin seat 44 respectively perform perforating and positioning on the workpiece holes of the excavator frame through hole alignment pins. Rotate the lateral strut 45 so that the lateral strut 45 telescopically moves towards each other in the horizontal direction to clamp the side wall of the excavator frame, which can prevent the excavator frame from shaking in the vertical direction during the machining process.

[0037] The horizontal locking components 5 on both sides of the hole positioning component 4 limit the excavator frame in the horizontal direction. Rotate the locking rod 511. Under the pushing of the locking rod 511, the side wall of the excavator frame is closely attached to the positioning baffle 52, preventing the excavator frame from shaking in the horizontal direction during the machining process.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
