[0019] Reference Figure 1 and Figure 2, an embodiment of the present application provides a frame combination device for a skid loader, including a base 10 and an inner support positioning seat and an outer limit seat 30 arranged on the top of the base 10. The base 10 has a relative length direction and a width direction, where the length direction and the width direction are two directions located in the same plane and perpendicular to each other. The outer limit seats 30 are symmetrically arranged on both sides of the length direction of the base 10 and are used to limit the skid loader frame 40 to be assembled on both sides, hereinafter simply referred to as the frame 40. The inner support positioning seat includes a support seat 21, a front inclined positioning seat 22, and a rear inclined positioning seat 23. The support seat 21 is close to the middle of the base 10 and is used to support the frame 40 at the central position or near the central position at the bottom of the frame 40. The front inclined positioning seat 22 and the rear inclined positioning seat 23 are respectively close to both ends of the length direction of the base 10 and are both facing the support seat 21. At the same time, in the height direction, the front inclined positioning seat 22 is lower than the rear inclined positioning seat 23, and a first inclined surface 221 is provided at the top of the side of the front inclined positioning seat 22 away from the rear inclined positioning seat 23. The first inclined surface 221 extends from the low end to the high end in the direction close to the rear inclined positioning seat 23 and is used to position and support the front inclined surface structure of the frame 40. A second inclined surface 231 is provided at the top of the side of the rear inclined positioning seat 23 close to the front inclined positioning seat 22, and the second inclined surface 231 extends from the low end to the high end in the direction close to the front inclined positioning seat 22 and is used to position and support the rear inclined surface structure of the frame 40. In this way, with the frame combination device for a skid loader provided by the present application, positioning and support can be formed for the frame 40 at the key parts of the frame 40, including the bottom, both sides, the front inclined surface structure, and the rear inclined surface structure. It is convenient and fast to assemble and form the frame, with high work efficiency and low labor intensity. At the same time, it is also convenient to carry out spot welding fixing operations by suspending and fixing the frame 40.

[0020] In one embodiment, two positioning pin shafts 222 are vertically connected to the first inclined surface 221, and at the same time, the two positioning pin shafts 222 are respectively close to both sides of the length direction of the base 10. Thus, on the basis of positioning and supporting the front inclined surface structure of the frame 40 through the first inclined surface 221, the frame 40 can be more accurately positioned by means of the cooperation between the two positioning pin shafts 222 and the holes at the front inclined surface structure of the frame 40, and the assembly quality of the frame 40 can be ensured.

[0021] In one embodiment, two tightening screws are vertically connected to the second inclined surface 231 in a threaded fit manner. At the same time, the two tightening screws are respectively close to both sides of the length direction of the base 10, and a tightening block 232 is vertically connected to one end of the tightening screw close to the front inclined positioning seat 22. Thus, the positions of the two tightening blocks 232 can be flexibly adjusted by rotating the tightening screws to tighten the rear inclined surface structure of the vehicle frame 40, so that the vehicle frame 40 can be maintained in the correct posture, facilitating the rapid assembly and forming of the vehicle frame 40.

[0022] In one embodiment, the outer limit seat 30 includes a pull-out positioning seat 31 and a pull-out limit plate 32. The pull-out positioning seat 31 is vertically connected to the base 10, and the pull-out limit plate 32 is arranged on the upper part of the pull-out positioning seat 31 in a manner that can move directionally along the width direction of the base 10. At the same time, a pressing plate 33 is vertically connected to the inner end of the pull-out limit plate 32. In this way, by changing the position of the pull-out limit plate 32 in the horizontal direction, the pressing plate 33 can be well abutted against both sides of the vehicle frame 40, and thus precise limits can be formed on both sides of the vehicle frame 40.

[0023] Further preferably, a pull ring 34 is arranged at the outer end of the pull-out limit plate 32 to facilitate pulling the pull-out limit plate 32. A plurality of positioning holes are evenly arranged in the moving direction of the pull-out limit plate 32 between the pressing plate 33 and the pull ring 34. At the same time, a positioning member 311 that cooperates with the positioning holes is installed on the pull-out positioning seat 31. In this way, when the pull-out limit plate 32 moves in place, the pull-out limit plate 32 can be fixed on the pull-out positioning seat 31 through the positioning member 311, and the limit stability of the pressing plate 33 can be ensured. The positioning member 311 can be a positioning pin.

[0024] In one embodiment, limit frames 51 are symmetrically installed on both sides of the base 10 at the rear inclined positioning seat 23. At the same time, a limit shaft 52 is vertically connected between the two limit frames 51, and the limit shaft 52 is close to the upper part of the limit frame 51. A spacer sleeve 53 for fitting and slidingly loading the inner hole of the vehicle frame is sleeved on the limit shaft 52. Thus, the inner hole of the vehicle frame 40 can be positioned through the spacer sleeve 53, and the accuracy of the inner hole is not easily damaged. In addition, a threaded sleeve 54 is also sleeved on the limit shaft 52 in a threaded fit manner, and a first limit block 55 is installed on the threaded sleeve 54. Thus, the horizontal position of the threaded sleeve 54 can be changed by rotating the threaded sleeve 54, and then a limit is formed on one side of the inner hole of the vehicle frame 40 through the first limit block 55 on the threaded sleeve 54, so as to further ensure the positioning accuracy of the rear end of the vehicle frame 40.

[0025] Further preferably, a rotating rod 56 is also connected to the lower part of the limiting frame 51. The rotating rod 56 vertically penetrates through the limiting frame 51 in a threaded fit manner. At the same time, a second limiting block 57 is vertically connected to the inner end of the rotating rod 56, and a rotating handle 58 is installed at the outer end of the rotating rod 56, so as to form a limit on both sides of the rear end of the vehicle frame 40 through the second limiting block 57. At the same time, the rotating rod 56 can be rotated more conveniently through the rotating handle 58, so that the limiting position of the second limiting block 57 can be adjusted flexibly.
