[0034] Embodiment 1

[0035] As Figure 1 and Figure 3 shown, a crawler chassis guide wheel assembly device includes: a frame fixing device 1 and a tensioning and guiding installation device 2. The frame fixing device 1 is used to support and fix the longitudinal beam 3; the tensioning and guiding installation device 2 is used to support the tensioning and guiding assembly 4 and drive the tensioning and guiding assembly 4 to move so as to be assembled to the longitudinal beam 3.

[0036] The tensioning installation device 2 includes a first sliding system 21, a second sliding system, a mounting frame, a lifting support frame 26, and two sets of lifting support platforms 25. The first sliding system 21 is used to drive the second sliding system to slide in the first direction (Y direction), and the second sliding system is used to drive the mounting frame to slide in the second direction (X direction). A third sliding system 23 and a fourth sliding system 24 are provided on the mounting frame. The third sliding system 23 is used to drive the lifting support platform 25 to slide in the first direction (Y direction) so as to adjust the distance between the two sets of lifting support platforms 25, and the fourth sliding system 24 is used to drive the lifting support frame 26 to slide in the second direction (X direction). The lifting support frame 26 is used to support the tension spring seat 41 of the tensioning assembly 4, and the two sets of lifting support platforms 25 cooperate to support the guide wheel 42 of the tensioning assembly 4.

[0037] The assembly is carried out by using the above assembly device, including the following steps:

[0038] Step 1: Use the frame fixing device 1 to support and fix the longitudinal beam 3.

[0039] Step 2: Adjust the heights of the two sets of lifting support platforms 25 to be flush with each other and make the height of the lifting support platform 25 the same as the height of the installation position of the guide wheel 42 on the track of the longitudinal beam 3.

[0040] Drive the lifting support platform 25 to slide through the third sliding system 23 so as to adjust the distance between the two sets of lifting support platforms 25 to be adapted to the support of the guide wheel 42 and make the lifting support frame 26 on the vertical bisector of the two sets of lifting support platforms 25.

[0041] Drive the lifting support frame 26 to slide through the fourth sliding system 24 so as to adjust the position of the lifting support frame 26 and adjust the height of the lifting support frame, so that the horizontal distance and vertical height difference between the lifting support frame 26 and the lifting support platform 25 are adapted to the guide wheel 42 of the tensioning assembly 4 and the tension spring seat 41 of the tensioning assembly 4.

[0042] Step 3: Install the tensioning assembly 4 on the tensioning installation device 2 (the tensioning assembly 4 includes a guide wheel 42 and a tension spring seat 41 connected to the guide wheel 42. During installation, place the guide wheel 42 between the two sets of lifting support platforms 25, and use the two sets of lifting support platforms 25 to support the shaft seats on both sides of the guide wheel 42 respectively, and place the tension spring seat 41 on the lifting support frame 26), and drive the mounting frame to move (in the Y direction) through the first sliding system 21 so that the guide wheel of the tensioning assembly 4 is aligned with the track of the longitudinal beam 3; then drive the second sliding system to drive the mounting frame to move towards the longitudinal beam 3 until the tensioning assembly 4 is installed on the longitudinal beam 3; finally, lower the lifting support platform 25 and the lifting support frame 26 to make the tensioning installation device 2 away from the longitudinal beam 3.

[0043] Embodiment 2

[0044] The difference between this embodiment and Embodiment 1 is that, as Figure 2 shown, the frame fixing device 1 includes a first base 16 and two groups of support beams 13. The two groups of support beams 13 slide along both ends of the first base 16 respectively. Two limit plates 14 are slidably arranged on each group of support beams 13. The two limit plates 14 are used to match longitudinal beams 3 with different widths and limit the longitudinal beams 3 in the Y direction. A limit rod 15 is further arranged on the support beam 13 at the end of the first base 16 far from the tensioning and installing device 2. The limit rod 15 can slide along the length direction of the frame fixing device. The limit rod 15 is used for positioning and limiting the longitudinal beam 3. When placing the longitudinal beam 3, generally the vertical plate 31 of the longitudinal beam 3 is attached to the end of the limit rod 15 far from the support beam 13.

[0045] For each group of support beams 13 on the first base 16, a first screw rod 17 and a first slide rail 12 are provided. The first slide rail 12 is along the X direction. The support beam 13 is threadedly connected to the first screw rod 17 and slides along the first slide rail 12. The first screw rod 17 is driven by a first motor 11. By driving the first motor 11, the support beam 13 can be driven to slide along the base. By adjusting the left and right support beams 13, longitudinal beams 3 with different lengths can be adapted.

[0046] The limit plate 14 is slidably connected to the support beam 13 through a chute plate. The chute plate is fixed on the support beam 13 through a first locking member. After sliding the limit plate 14 along the support beam 13 to adapt to the width of the longitudinal beam 3, the chute plate can be fixed by using the first locking member. In this embodiment, the first locking member adopts a locking screw. Scale lines are provided on the support beam 13 to facilitate recording the moving distance of the limit plate 14 under a certain model of longitudinal beam 3.

[0047] The limit rod 15 is detachably fixed on the support beam 13 through a second locking member. A scale is provided on the limit rod 15. The lengths of different models of longitudinal beams 3 are different. By adjusting the protruding distance of the limit rod 15 on the support beam 13, the vertical plate 31 of the longitudinal beam 3 is attached to the end of the limit rod 15 to position the longitudinal beam 3.

[0048] The first sliding system includes a first bottom plate, a first driving motor 211 installed on the first bottom plate, a second screw rod 212 connected to the first driving motor 211, and a second slide rail 213 arranged along the first direction. The second slide rail 213 is along the Y direction. The second sliding system is threadedly connected to the second screw rod 212 and slidably connected to the second slide rail 213. Thus, the first sliding system 211 can drive the mounting frame and the second sliding system to move in the Y direction.

[0049] The second sliding system includes a second bottom plate, a second driving motor, a third screw rod 224 connected to the second driving motor, and a third slide rail. The third slide rail is arranged along the X direction. The second bottom plate is threadedly connected to the second screw rod 212 and is slidably connected to the second slide rail 213. The mounting bracket is threadedly connected to the third screw rod 224 and is slidably connected to the third slide rail. Thus, the second driving motor can drive the mounting bracket to move along the X direction.

[0050] The third sliding system 23 includes a third bottom plate, a third driving motor 231, a fourth screw rod 232 and a fourth slide rail 233 connected to the third driving motor 231. The fourth slide rail 233 is arranged along the Y direction. The second base 251 of the lifting support platform 25 is threadedly connected to the fourth screw rod 232 and is slidably connected to the fourth slide rail 233. Two sets of the third sliding system 23 can be provided, and the two sliding systems respectively control two lifting support platforms 25. Alternatively, the two ends of the fourth screw rod 232 can adopt reverse screw rods, and the reverse rotation of the fourth screw rod 232 drives the two lifting support platforms 25 to move in opposite directions, so that the distance between the two lifting support platforms 25 can be adjusted.

[0051] The fourth sliding system 24 is arranged on one side of the mounting bracket close to the vehicle frame fixing device 1. The fourth sliding system 24 includes a fourth driving motor 241, a fifth slide rail 243, and a fifth screw rod 242 connected to the fourth driving motor 241. The fifth slide rail 243 is along the X direction. The third base 261 of the lifting support frame 26 is threadedly connected to the fifth screw rod 242 and is slidably connected to the fifth slide rail 243. The fourth driving motor 241 can drive the lifting support frame 26 to move along the X direction.

[0052] As Figure 4 shown, the lifting support platform 25 includes a second base 251, a support platform 252, a first telescopic cylinder 253, and a guiding telescopic rod 254. One end of the first telescopic cylinder 253 is connected to the second base 251, and the other end is connected to the support platform 252. The guiding telescopic rod 254 is arranged between the second base 251 and the support platform 252. The second base 251 is slidably connected to the third sliding system 23. The first telescopic cylinder 253 drives the support platform 252 to lift.

[0053] The lifting support frame 26 includes a third base 261, a support frame 262, and a second telescopic cylinder 263. The second telescopic cylinder 263 is installed on the third base 261. The telescopic end of the second telescopic cylinder 263 is connected to the support frame 262. The base is slidably connected to the fourth sliding system 24. The second telescopic cylinder 263 can drive the support frame 262 to lift.

[0054] The controller is also included, and the controller is connected to the frame fixing device 1 and the tensioning and installing device 2. For different types of crawler chassis, different automatic control programs are set, and the position instructions of the corresponding models are recorded in the program. When the chassis type is switched, the controller calls the corresponding control program, and the flexible production of different varieties can be realized, avoiding the quality instability problem caused by manual assembly.

[0055] Example 3

[0056] This embodiment also provides a method for assembling guide wheels of a crawler chassis, which is assembled using the assembly device described in Embodiment 2, and includes the following steps:

[0057] Step 1: Use the frame fixing device 1 to support and fix the longitudinal beam 3.

[0058] The specific steps are as follows: before assembly, the position of the longitudinal beam 3 in the frame fixing device 1 is simulated in the three-dimensional software according to the length and width of the longitudinal beam 3. The preferred position is that the supporting wheel mounting base of the longitudinal beam 3 falls on the support beam 13 of the frame adjustment device, and the left and right support beams 13 are basically symmetrical relative to the center of the longitudinal beam 3. According to the simulation results, the limit rod 15 on the support beam 13 away from the end of the tensioning installation device 2 is set so that the longitudinal beam 3 is placed behind the support rod and close to the vertical plate 31 of the longitudinal beam 3.

[0059] According to the position result of the simulation setting, the first motor 11 works to move the support beams 13 at both ends to the specified position; adjust the limit rod 15 so that the longitudinal beam 3 is placed behind the support rod and close to the longitudinal beam 3 vertical plate 31; move the limit plate 14 on the support beam 13 so that the distance between the two limit plates 14 on the same support beam 13 is consistent with the width of the longitudinal beam 3. Place the longitudinal beam 3 on the frame fixture 1, and the end of the limit rod is close to the longitudinal beam 3 vertical plate 31. So far, the longitudinal beam 3 has been fixed on the frame fixture 1. Record the displacement of the limit rod.

[0060] Step 2: First, pre-set the tensioning and guiding installation device 2 according to the external dimensions of the tensioning and guiding assembly 4:

[0061] like Figure 5 As shown, the dimensions of the tensioning assembly 4 are as follows: L1: inner gear of the guide wheel 42 axle seat;

[0062] L2: distance from the center of the guide wheel 42 to the tension spring seat 41;

[0063] L3: height difference between the bottom surface of the axle of the guide wheel 42 and the tension spring seat 41.

[0064] The height of the two sets of support platforms 252 are adjusted by telescoping the first telescopic cylinder 253 and the second telescopic cylinder 263 so that the two support platforms 252 are flush and the height of the lifting support platform 25 is the same as the height of the installation position of the guide wheel 42 on the track of the longitudinal beam 3;

[0065] Operate the third driving motor 231 to drive the second base 251 to drive the support platform 252 to slide, so that the distance between the two groups of support platforms 252 is adapted to the support of the guide wheel 42 (slightly larger than L1) and the lifting support frame 26 is on the vertical bisector of the two groups of lifting support platforms 25;

[0066] Operate the fourth driving motor 241 to drive the third base 261 to drive the support frame to slide, and adjust the position and height of the lifting support frame 26 (keep the tensioning assembly 4 horizontal after placement), so that the horizontal and vertical distances between the lifting support frame 26 and the lifting support platform 25 are adapted to the guide wheel 42 of the tensioning assembly 4 and the tension spring seat 41 of the tensioning assembly 4.

[0067] Step three, as Figure 6 shown, install the tensioning assembly 4 on the tensioning installation device 2, and drive the mounting frame to move through the first sliding system 21, so that the guide wheel of the tensioning assembly 4 is aligned with the track of the longitudinal beam 3; then drive the second sliding system to drive the mounting frame to move towards the longitudinal beam 3 until the tensioning assembly 4 is installed on the longitudinal beam 3, as Figure 7 and Figure 8 shown; finally, lower the lifting support platform 25 and the lifting support frame 26 to move the tensioning installation device 2 away from the longitudinal beam 3.

[0068] The present invention replaces manual operation with automated equipment, improves the operation efficiency, and greatly reduces the manual operation intensity and operation risk; at the same time, for different models of crawler chassis, by setting different automatic control programs and recording the position instructions of the corresponding models in the programs, when the chassis type is switched, the corresponding control program is called to achieve flexible production of different varieties, avoiding the problem of unstable quality caused by manual assembly.

[0069] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood through specific situations.

[0070] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the technical field, without departing from the technical principle of the present application, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present application.
