Description

Technical Field

[0001] This utility model relates to the technical field of bucket tooth assembly, and in particular to a bucket tooth assembly device. Background Technology

[0002] In the field of construction machinery, the connection between the bucket and the shovel teeth mostly relies on pins. Currently, the installation and removal of pins generally adopts the traditional hammering method. During operation, workers need to use tools such as hammers to repeatedly strike the pin, using the impact force to force the pin into or out of the connection hole. This method has obvious drawbacks: on the one hand, the instantaneous impact force generated by hammering is difficult to control, which can easily lead to bending of the pin, deformation of the shovel teeth or bucket connection, or even damage to the internal structure of the metal, shortening the service life of the parts; on the other hand, manual hammering requires continuous application of a large amount of physical force, which is laborious and inefficient. Especially when the pin is in an interference fit or is rusted, it often requires the cooperation of many people to complete the task, which takes a long time. Utility Model Content

[0016] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0017] The bucket and shovel tooth assembly device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown, the bucket tooth assembly device of this utility model embodiment includes: The shovel tooth clamp 1 is used to fix it to the outside of the shovel tooth.

[0019] The pin-driven force-applying component is connected to the shovel tooth clamp 1. The pin-driven force-applying component includes a frame 2, a first lead screw bearing seat, a first rotating lead screw 3, a threaded slider 4, and a pin-driven pusher 5. The first lead screw bearing seat is located inside the frame 2. The first rotating lead screw 3 is rotatably connected inside the frame 2. The threaded slider 4 is slidably connected inside the frame 2. The threaded slider 4 is threadedly connected to the first rotating lead screw 3. The pin push head 5 is connected to the threaded slider 4.

[0020] Specifically, in a certain type of bucket tooth assembly device, the teeth are first aligned with the pin holes of the bucket, and then fixed by engaging the tooth clamp 1 with the outer protruding part of the tooth. The pin is then inserted into the corresponding pin groove of the tooth and bucket. At this time, the pin-applying component is operated: the first rotating screw 3, limited by the first screw bearing seat, rotates under external force, driving the threaded slider 4 to move along the guide groove of the frame 2. The front pin pusher 5 then precisely acts on the pin. When the screw is rotated forward, the pusher smoothly presses the pin into the connecting hole to complete the assembly.

[0021] In one embodiment of the present invention, the shovel tooth clamp 1 includes a fixing block 6 and an adjusting block 7. The fixing block 6 is fixed to the bottom surface of the frame 2, and the adjusting block 7 slides on the bottom surface of the frame 2. A second bearing seat is provided on the fixing block 6, and a second rotating screw 8 is rotatably connected to the center of the second bearing seat. The second rotating screw 8 is threadedly connected to the adjusting block 7, and a screw head 9 is connected to the end of the second rotating screw 8.

[0022] Specifically, the second bearing seat on the fixed block 6 provides stable support for the second rotating lead screw 8, allowing the lead screw to rotate freely around its own axis without axial displacement. When the screw head 9 at the end of the second rotating lead screw 8 is rotated, the lead screw drives the adjusting block 7 through threaded transmission: rotating the screw head 9 clockwise moves the adjusting block 7 closer to the fixed block 6, using the clamping space between them to clamp the outer side of the shovel teeth. Rotating counterclockwise moves the adjusting block 7 away, releasing the shovel teeth. This structure achieves stepless adjustment through the precision transmission of the lead screw, adapting to the outer protrusions of the shovel teeth with different thicknesses and curvatures, ensuring the relative fixation of the shovel teeth and the device during assembly, and providing a stable reference for subsequent pin assembly and disassembly.

[0023] In one embodiment of the present invention, a torque assembly 10 is further included, the output end of which is connected to one end of the first rotating lead screw 3.

[0024] Specifically, it facilitates the application of force by the user.

[0025] In one embodiment of the present invention, the torque assembly 10 includes a large gear, a small gear, and a gearbox. The large gear and the small gear are rotatably connected inside the gearbox. The large gear and the small gear are meshed together. The central shaft of the large gear is connected to one end of the first rotating lead screw 3. The central shaft of the small gear is connected to a hexagonal chuck.

[0026] Specifically, the torque assembly 10 of the device adopts a gear transmission structure. Both the large gear and the small gear are rotatably connected inside the gearbox via bearings, and the two are kept in a meshing state. The central shaft of the large gear is coaxially fixed to one end of the first rotating lead screw 3, and the central shaft of the small gear extends outward and is connected to a hexagonal chuck. During operation, the user inserts a wrench into the hexagonal chuck to rotate the small gear, which drives the large gear to rotate through gear meshing. The difference in the number of teeth between the two gears creates a mechanical gain.

[0027] In one embodiment of this utility model, such as Figure 2 As shown, the bucket tooth assembly device of this embodiment also includes a one-way wrench 11. The one-way wrench 11 includes an outer shaft and an inner shaft. The inner shaft is rotatably connected to the center of the outer shaft. A ratchet is provided on the inner side of the outer shaft, and a ratchet is provided on the outer side of the inner shaft. The ratchet abuts against the ratchet. A lever is connected to the outer wall of the outer shaft.

[0028] Specifically, the ratchet on the inner side of the outer shaft and the ratchet on the outer side of the inner shaft form a one-way abutment structure, and a lever is vertically fixed to the outer wall of the outer shaft. In use, the end of the inner shaft is fitted and connected to the hexagonal chuck of the torque assembly 10. When the lever is reciprocated, the outer shaft drives the ratchet to rotate unidirectionally through the ratchet, driving the pinion to rotate continuously. When the lever is reversed, the ratchet disengages from the ratchet and spins freely, allowing continuous force to be applied without disassembling the wrench.

[0029] In one embodiment of this utility model, such as Figure 2As shown, the threaded slider 4 is provided with an extension rod 12, and the pin push head 5 slides on the extension rod 12.

[0030] Specifically, this allows the pusher head to gain additional telescopic adjustment capability while moving synchronously with the slider, adapting to the position of the pin shaft.

[0031] In one embodiment of this utility model, the pin pusher 5 is detachably connected to the extension rod 12.

[0032] Specifically, different pin pushers 5 can be selected depending on the type of pin.

[0033] The entire assembly process is as follows: First, align the shovel teeth with the pin holes of the bucket, rotate the screw head 9 of the second rotating screw 8 in the shovel tooth clamp 1, drive the adjusting block 7 to slide along the bottom surface of the frame 2, so that the fixing block 6 and the adjusting block 7 clamp the outer side of the shovel teeth, and adapt to different specifications of shovel teeth through the stepless adjustment of the screw drive to ensure that the device and the shovel teeth are relatively fixed.

[0034] Then, the pin is placed into the corresponding pin slot, and the inner shaft of the one-way wrench 11 is connected to the hexagonal chuck of the torque assembly 10. During operation, the lever of the one-way wrench 11 is reciprocated, and the outer shaft drives the inner shaft to rotate in one direction through the ratchet, which drives the small gear in the gearbox to rotate. The small gear meshes with the large gear to form mechanical gain, which drives the first rotating screw 3 to rotate. The threaded slider 4 moves horizontally along the guide groove of the frame 2, and the extension rod 12 on it can adjust the sliding stroke of the pin pusher 5 according to the position of the pin, so that the pusher is precisely aligned with the pin. When force is applied in the forward direction, the pusher smoothly presses the pin into the connection hole between the shovel teeth and the bucket.

[0035] In summary, the bucket tooth assembly device of this utility model can avoid damage from hammering, is easier to operate, has accurate positioning, high assembly and disassembly efficiency, and can be adapted to various teeth, reducing the trouble of tool replacement.
