[0027] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0028] See attached Figure 1 and attached Figure 3 The utility model discloses an excavator crawler beam guide frame assembly device, which includes a working platform 1, four corners of the bottom of the working platform 1 are equipped with support legs, the bottom of the support legs are equipped with support plates to maintain the stability of the device, and a middle positioning device 2 that can move forward and backward is installed in the middle of the working platform 1. The middle positioning device 2 is symmetrically provided with two side clamping devices 3 on the left and right sides, and a front clamping device 4 is provided on the front side of the middle positioning device 2. Figure 1As shown, the side clamping device 3 and the front clamping device 4 both include a first base 31 and a lead screw 32. The first base 31 of the side clamping device 3 is installed on the work platform 1. The first base 31 is an inverted T-shaped bracket, and a reinforcing rib is welded on the outer side thereof. The upper part of the first base 31 of the side clamping device 3 is provided with a lead screw 32 horizontally passing through the first base 31 in the left-right direction. The upper part of the first base 31 of the front clamping device 4 is provided with a lead screw 32 horizontally passing through the first base 31 in the front-back direction. A hand wheel 33 is installed at the outer end of the lead screw 32. A pressure head 34 is connected to the inner end of the lead screw 32. The pressure head 34 is rotatably installed at the inner end of the lead screw 32. In order to more conveniently operate the hand wheel 33, the hand wheel 33 is arranged outside the first base 31. The first base 31 is provided with a limit rod 35 which is arranged parallel to the lead screw 32. The limit rod 35 is rotatably installed on the first base 31. One side of the reinforcing rib on the first base 31 is the lead screw 32, and the other side is the limit rod 35. A pressing sleeve 37 is rotatably installed on the inner end of the lead screw 32. The pressing sleeve 37 is a U-shaped frame with an opening facing the pressing head 34. The pressing sleeve 37 is fixedly sleeved on the pressing head 34. The inner side wall of the pressing head 34 is flush with the inner side wall of the pressing sleeve 37 or extends inwardly from the inner side wall of the pressing sleeve 37. In order to prevent the pressing head 34 and the pressing sleeve 37 from fitting together and causing the pressing head 34 to be unable to rotate and be easily damaged, a groove is provided on the inner side wall of the pressing head 34 along its length. The outer side here refers to the side away from the intermediate positioning device.

[0029] As a further explanation of this embodiment, refer to the attached Figure 1 A rear positioning device 5 is provided at the rear side of the intermediate positioning device 2. The rear positioning device 5 includes a second base 51 installed on the working platform 1. The second base 51 is provided with a plurality of through holes for installing stop pins 52 and pillars 53. Stop pins 52 are provided on both the left and right parts of the second base 51. A pillar 53 is provided between the two stop pins 52. Preferably, four pillars 53 are provided, one at each of the four corners of the second base 51. The length of the stop pin 52 is greater than the length of the pillar 53. Figure 2 As shown, when the end plate 14 is placed on the rear positioning device 5, the two stop pins 52 respectively abut the left and right sides of the end plate 14, and the support 53 abuts the rear side wall of the end plate 14. During use, when the positioning of a type of guide frame is completed, the two stop pins 52 corresponding to this type are removed, and the two stop pins 52 corresponding to other types of guide frames are installed, so as to position the end plate 14.

[0030] As a further explanation of this embodiment, refer to the attached Figure 1 , two arc plate positioning blocks 62 are symmetrically arranged on the left and right sides of the middle positioning device 2, and the two arc plate positioning blocks 62 are installed on the working platform 1 and are located between the clamping devices 3 on both sides. Figure 2As shown, when the two arc plate welds 18 are placed on the two arc plate positioning blocks 62, the two arc plate positioning blocks 62 abut against the bottom of the two arc plate welds 18, and an end plate positioning block 61 is installed on the front side of the rear positioning device 5. Preferably, two end plate positioning blocks 61 are symmetrically arranged on the left and right, and the end plate positioning blocks 61 and the stop pins 52 overlap in the vertical direction. Figure 2 As shown, when the end plate 14 is placed on the end plate positioning block 61 , the end plate positioning block 61 abuts against the bottom of the end plate 14 .

[0031] When in use, first place the two inverted L-shaped arc plate welds 18 on the left and right sides of the middle positioning device 2 and position them, and at the same time place the bottoms of the two arc plate welds 18 on the arc plate positioning block 62, and then turn the hand wheel 33. The hand wheel 33 rotates while driving the lead screw 32 to rotate inward. Since the lead screw 32 is rotatably mounted on the pressing sleeve 37, the inward movement of the lead screw 32 drives the pressing sleeve 37 and the pressure head 34 to move inward as well, until the pressure head 34 abuts against the outer sides of the two arc plate welds 18, that is, away from the side of the middle positioning device 2. After the positioning is completed, the two arc plate welds 18 are assembled. After spot welding, the reinforcing plate 19 is placed above the two arc plate welds 18 and welded to the arc plate welds 18 after spot welding. Then, the rectangular end plate 14 is placed from top to bottom on the rear positioning device. At this time, the pillar 53 abuts against the rear side wall of the end plate 14, and the two side edges of the end plate 14 abut against the two stop pins 52 respectively. The bottom of the end plate 14 is placed on the end plate positioning block 61, and then the end plate 14 is welded to the arc plate weld 18 after spot welding. The side with a large area of ​​the end plate 14 faces the arc plate weld 18. After welding is completed, the welded guide frame is lifted away with a sling. During use, when the pressure head 34 moves inward, the pressure head 34 will rotate in the pressing sleeve 37. The setting of the limit rod 35 can prevent the pressure head 34 from deflecting. The pressure head 34 will rotate in the pressing sleeve 37. The setting of the groove 36 prevents the pressure head 34 from fitting with the pressing sleeve 37, and the pressure head 34 cannot rotate and is easily damaged.

[0032] As a further explanation of this embodiment, refer to the attached Figure 1-3The intermediate positioning device 2 includes an intermediate support 21 installed on the working platform 1. The left and right side walls of the intermediate support 21 are both provided with two groove clamps 22 symmetrically arranged front and back. A T-shaped slider 23 is provided between the two groove clamps 22. The front and rear sides of the T-shaped slider 23 are respectively slidably connected to the front and rear groove clamps 22. Positioning rollers 24 are installed at both upper and lower ends of the T-shaped slider 23. A positioning shaft 25 is installed in the middle of the T-shaped slider 23. When the guide frame 13 is placed on the intermediate positioning device 2, the outer diameter of the positioning roller 24 rolls in contact with the side wall of the guide frame horizontal plate 16, and the outer diameter of the positioning shaft 25 rolls in contact with the bottom surface of the guide frame vertical plate 17 located on the upper part of the T-shaped slider 23. When in use, select a T-shaped slider 23 that is suitable for the model of the guide frame and put it into the groove clamp 22. The T-shaped slider 23 is equipped with a positioning roller 24 and a positioning shaft 25 of a corresponding model. The two arc plate welds 18 formed by spot welding the guide frame cross plate 16 and the guide frame vertical plate 17 with the two arc plates 15 are placed on the tooling respectively. The positioning roller 24 rolls in contact with the side wall of the guide frame cross plate 16, and the outer diameter of the positioning shaft 25 abuts against the bottom surface of the guide frame vertical plate 17 located on the upper part of the T-shaped slider 23 to complete the positioning of the two arc plate welds. Since the contact support between the guide frame and the tooling is mainly completed by the outer diameter of the positioning roller 24 and the positioning shaft 25, the tooling can be detached from the bottom of the guide frame by moving the slide plate 7 on the guide rail 8 to complete a pairing operation. When it is necessary to assemble a guide frame of other models, the T-shaped slider 23 of the corresponding model can be replaced at this time. The T-shaped slider 23 is also equipped with a positioning roller 24 and a positioning shaft 25 of the corresponding model.

[0033] As a further explanation of this embodiment, refer to the attached Figure 1 A slide plate 7 is installed under the intermediate positioning device 2, a guide rail 8 is arranged on the working platform 1, and a long slider 9 adapted to the guide rail 8 is arranged on the lower surface of the slide plate 7. The slide plate 7 can slide back and forth on the guide rail 8 through the long slider 9. The first base 31 of the front clamping device 4 is arranged on the slide plate 7. When in use, the front clamping device 4 and the intermediate positioning device 2 can slide on the slide plate 7 with the slide plate 7.

[0034] As a further explanation of this embodiment, refer to the attached Figure 1 and attached Figure 2 A positioning seat 10 is installed on one side wall of the skateboard 7, and a pin shaft 11 is slidably arranged in the positioning seat 10. A through hole is opened in the positioning seat 10, and the pin shaft 11 can slide up and down in the through hole. A skateboard limit block 12 corresponding to the positioning seat 10 is installed on the working platform 1, and a positioning hole matching the pin shaft 11 is opened on the skateboard limit block 12. When the skateboard 7 slides forward until the pin shaft 11 is located above the skateboard limit block 12, the pin shaft 11 can be inserted downward into the positioning hole in the skateboard limit block 12 to fix the skateboard 7.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
