Description

Technical Field

[0001] The invention relates to the technical field of automated processing of a bulldozer blade assembly, in particular to automated drilling equipment for a bulldozer blade assembly. Background Art

[0002] The bulldozer blade is a key component at the front end of the bulldozer, generally used to push soil, rocks and other materials. The design and structure of the bulldozer blade usually directly affect the working efficiency and working results of the bulldozer; in the prior art, the bulldozer blade assembly is generally composed of a plurality of shovel plates with a certain arc, and the shovel plate is usually provided with a plurality of circular holes arranged at equal intervals through a drilling device. The circular holes can not only reduce the weight of the shovel plate, but also reduce the resistance it encounters during the use of the shovel plate, and disperse the stress on its surface, thereby reducing the risk of cracking and damage of the shovel plate.

[0003] However, the traditional method of drilling holes in the shovel plate has the following problems: 1. The method of drilling holes in the shovel plate in the prior art is generally to first position and drill holes in the shovel plate, then transport the shovel plate to the specified position, and then use a cleaning device to clean the debris in the opened circular hole. This operation method generally requires multiple drive sources to process the shovel plate in steps, resulting in poor continuity and low efficiency between the operation steps, and high overall use and maintenance costs of the drilling equipment; 2. When drilling holes in the shovel plate in the prior art, the drilling device generally lacks the necessary guiding and positioning, resulting in poor consistency in the spacing between the circular holes, which leads to uneven stress distribution on the surface of the shovel plate during actual use, and further greatly increases the risk of cracking and damage to the shovel plate.

[0037] See also Figure 2 The adjusting assembly 35 comprises a threaded rod 351, an adjusting seat 352, a threaded sleeve 353, an electric push rod 354, a front stopper 355, a positioning hole 356, a spring rod three 357 and a rear stopper 358; the end of the connecting frame 32 is fixedly provided with a threaded rod 351 through a support three, the surface of the threaded rod 351 is sleeved with an adjusting seat 352 slidably connected to the guide rod one 31, and a threaded sleeve 353 threadedly connected to the threaded rod 351 is rotatably provided on the vertical section of the adjusting seat 352, wherein an electric push rod 354 is fixedly provided on the lower surface of the horizontal section of the adjusting seat 352 on the front side, and a front stopper 355 is fixedly provided at the telescopic end of the electric push rod 354, and a positioning hole 356 is opened in the front stopper 355, wherein the horizontal section of the adjusting seat 352 on the rear side is symmetrically elastically slidably provided with a spring rod three 357, and the upper ends of the spring rods three 357 are jointly fixed with a rear stopper 358.

[0038] The driving mechanism 6 can intermittently drive the conveying roller 221 to rotate, so that the conveyor belt 222 drives the clamping seat 223 to intermittently move forward a specific distance, and the clamping seat 223 then drives the insertion rod 333 and the connecting frame 32 to move forward a specific distance synchronously along the guide rod 31, and the connecting frame 32 then drives the shovel plate to move forward a specific distance synchronously on the supporting roller 213 through the front stop block 355 and the rear stop block 358, wherein the supporting roller 213 and the baffle 214 can ensure the stability of the shovel plate when moving.

[0039] Since the rear stop block 358 is a wedge-shaped block structure, when the shovel plate is loaded to between the front stop block 355 and the rear stop block 358, the rear stop block 358 can be pressed downward by the front end of the shovel plate against the inclined surface on the rear side of the rear stop block 358 until the front end of the shovel plate passes over the rear stop block 358 to complete the loading. At this time, the rear stop block 358 can be reset upward again under the action of the spring rod three 357 and the rear end of the shovel plate can be limited. This operation method can improve the loading efficiency and convenience of the shovel plate.

[0040] When it is necessary to unload the shovel plate that has completed the drilling process, the front stopper 355 can be driven downward by the electric push rod 354 until the shovel plate can slide out from above the front stopper 355; when shovel plates of different lengths are to be limited between the front stopper 355 and the rear stopper 358, the distances between the front stopper 355 and the rear stopper 358 and the corresponding ends of the connecting frame 32 can be adjusted respectively by the spiral transmission of the threaded sleeve 353 and the threaded rod 351, so as to adapt to the limitation of shovel plates of different lengths, thereby improving the scope of application of the shovel plate drilling processing equipment.

[0041] When the shovel plate is driven to move forward intermittently a specific distance through the conveyor belt 222 and the connecting frame 32, the positioning card 343 that moves synchronously with the connecting frame 32 is engaged with the corresponding card slot 212 under the action of the spring rod 242, so that the connecting frame 32 and the shovel plate cannot continue to move forward without the action of external drive, so that the shovel plate is synchronously stationary and stably positioned with the connecting frame 32. This operation mode can realize synchronous adaptive positioning while intermittently conveying the shovel plate at a fixed distance, which not only ensures the consistency of the shovel plate conveying distance, but also ensures the stability and efficiency of the shovel plate conveying positioning, thereby ensuring the quality of subsequent drilling processing on the shovel plate.

[0042] See also Figure 1 The drilling mechanism 5 includes a fixed plate 51, a drilling assembly 52 and a cleaning assembly 53; a fixed plate 51 that moves up and down is provided on one side of the support frame 4 close to the center, a drilling assembly 52 is provided on the fixed plate 51, and a cleaning assembly 53 is provided on the front side of the drilling assembly 52.

[0043] See also Figure 3 and Figure 4The drilling assembly 52 includes a guide rod 2 521, a driven plate 522, a sliding shaft 1 523, a drilling cutter 524, a spring rod 4 525 and a pressure plate 526; the upper side of the fixed plate 51 is symmetrically fixed with a guide rod 2 521 that is slidably connected to the horizontal section of the support frame 4, the upper side of the fixed plate 51 is symmetrically fixed with a driven plate 522, the upper end of the driven plate 522 is fixed with a sliding shaft 1 523 on the side close to the center of the fixed plate 51, the lower side of the fixed plate 51 is fixed with a drilling cutter 524, the lower side of the fixed plate 51 is symmetrically elastically slidably provided with spring rods 4 525, and the lower ends of the spring rods 4 525 are commonly fixed with a pressure plate 526.

[0044] When drilling is to be performed on the stably positioned shovel plate, the driving mechanism 6 drives the sliding shaft 523 to move up and down a certain distance, and the fixed plate 51 drives the pressure plate 526 and the drilling milling cutter 524 to move up and down synchronously; when the fixed plate 51 moves downward by a specific distance, the pressure plate 526 first contacts the shovel plate and presses on the upper surface of the shovel plate. At this time, as the fixed plate 51 continues to move downward, under the action of the spring rod four 525, the pressure plate 526 can always maintain a stable pressing limit on the upper surface of the shovel plate until the drilling milling cutter 524 contacts the shovel plate and completes a drilling and cutting of the shovel plate. At this time, the fixed plate 51 moves upward under the action of the driving mechanism 6 until it is reset, thereby realizing the drilling and cutting of a circular hole on the surface of the shovel plate. This operation mode can ensure the stability of the shovel plate during the drilling process, thereby ensuring the stability and processing accuracy of the shovel plate drilling and cutting of the circular hole.

[0045] See also Figure 3 and Figure 4 The cleaning assembly 53 includes a limit rod 531, a guide groove 532, a positioning sleeve 533, a sliding shaft 534 and a brush head 535; the front side of the horizontal section of the support frame 4 is fixedly provided with a limit rod 531 through a support four, and the lower section of the limit rod 531 is provided with a guide groove 532, and the guide groove 532 is composed of a spiral groove on the upper side and a vertical straight groove on the lower side. The front side of the fixed plate 51 is rotatably provided with a positioning sleeve 533 that is slidably connected to the limit rod 531 through a support five, and the upper end of the inner surface of the positioning sleeve 533 is fixedly provided with a sliding shaft 534 that slidably cooperates with the guide groove 532, and the lower end of the positioning sleeve 533 is fixedly provided with a brush head 535.

[0046] When the driving mechanism 6 drives the fixing plate 51 to move downward, the positioning sleeve 533 moves downward synchronously along the limiting rod 531, and the sliding shaft 534 first drives the positioning sleeve 533 and the brush head 535 to rotate synchronously during the downward movement through the sliding cooperation with the spiral groove of the guide groove 532, and the brush head 535 is then inserted downward into the adjacent circular hole opened on the front side of the shovel plate, and rotates and cleans synchronously during the insertion process, thereby cleaning the residual debris in the adjacent circular hole, until the synchronously moving pressing plate 526 contacts and presses the shovel plate, at this time, the sliding shaft 534 slides with the vertical straight groove of the guide groove 532, so that the lower end of the positioning sleeve 533 moves downward stably and is inserted into the adjacent circular hole, so that the positioning sleeve 533 It cooperates with the adjacent circular holes to position until the drilling milling cutter 524 contacts the shovel board and completes drilling and cutting holes in the shovel board. At this time, the positioning sleeve 533 moves up and resets synchronously with the fixed plate 51. This operation method can not only achieve stable limiting and drilling of the shovel board, but also can simultaneously achieve debris cleaning of the opened circular holes. At the same time, by coordinating the positioning sleeve 533 with the adjacent circular holes that have been opened, the drilling milling cutter 524 can more accurately drill holes in the shovel board at equal intervals, thereby improving the accuracy of the shovel board drilling processing and the consistency of the spacing between the opened circular holes, thereby improving the uniformity of the surface stress distribution of the shovel board during actual use, and reducing the risk of cracking and damage of the shovel board due to uneven stress distribution.

[0047] When drilling and cutting the first circular hole at the front end of the shovel plate, the positioning sleeve 533 cooperates with the positioning hole 356 in the front stopper 355 to ensure the accuracy and stability of the position of the first circular hole, thereby improving the uniformity and quality of the overall drilling and cutting of the circular holes on the shovel plate surface.

[0049] When the conveying roller 221 is driven to drive the conveyor belt 222 to convey the connecting frame 32 forward, the motor 62 drives the half gear 63 to rotate in a directional manner (such as Figure 5 As shown in the figure), the half gear 63 drives the active bevel gear 65 to rotate synchronously through intermittent meshing transmission with the gear 1 64, and the active bevel gear 65 drives the rotating rod 66 to rotate in a directional manner through meshing transmission with the driven bevel gear 67.

[0051] When the fixed plate 51 is driven to move up and down a certain distance, the motor 62 drives the half gear 63 to rotate in a certain direction (such as Figure 5 As shown in the figure, at this time, the half gear 63 has been disengaged from the gear one 64, and the half gear 63 then drives the gear two 613 and the driving column 611 to rotate half a circle through the meshing transmission with the ratchet 616 on the side surface of the gear two 613, wherein the ratchet 616 can stably mesh with the half gear 63 with the cooperation of the blocking column 615 and the stop plate 617, and the driving column 611 then drives the sliding shaft one 523 and the fixed plate 51 to move up and down a fixed distance through the driving groove 612, thereby completing a drilling and cutting of a hole on the shovel plate. This operation mode can realize the intermittent fixed distance conveying and positioning, limited drilling and stable cleaning of the shovel plate in sequence through the same motor 62 as the driving source, which not only improves the continuity between the various processing operations and the consistency of the processing effect, but also improves the efficiency of the overall drilling processing of the shovel plate, while reducing the overall use and maintenance cost of the drilling processing equipment.

[0052] After the shovel plate completes processing and unloads the material, the motor 62 drives the half gear 63 to rotate in the opposite direction, and the reverse driving gear 1 64 can be used to drive the conveyor belt 222 to drive the connecting frame 32 to move backward and reset, and the ratchet 616 can cooperate with the rotation of the side surface of the gear 2 613 without meshing with the half gear 63, wherein the spring connector 618 can ensure that the ratchet 616 can be stably reset after directional rotation. This operation method can avoid the fixed plate 51 and the drilling milling cutter 524 from still cooperating when the connecting frame 32 is reset in the opposite direction.
