Description

Technical Field

[0001] This utility model belongs to the field of scraping and grinding technology, specifically relating to a tool that can efficiently improve scraping and grinding efficiency. Background Technology

[0002] During the installation of the wedge, to ensure a high-precision fit between the wedge and the contact surface and eliminate microscopic unevenness, repeated scraping and positioning operations are required to gradually optimize the surface accuracy of the wedge, thereby ensuring the stability of the equipment and uniform load distribution. In this process, the wedge needs to be repeatedly pulled out and put back in to complete multiple scraping and adjustments.

[0003] Traditional methods of disassembling and assembling wedges typically rely on two people working together, using a hammer to strike the wedges from side to side. However, this method has significant drawbacks: firstly, the striking force can easily deform the wedge or the equipment base, directly compromising the already scrapped fit and potentially rendering the workpiece unusable; secondly, this method is time-consuming and labor-intensive, generating substantial manpower and time losses during repeated strikes, significantly reducing scraping efficiency. Currently, some people use tools to fix the positioning pins on the wedges to facilitate their removal and insertion. However, current tools lack a quick-fitting structure for connecting or disassembling the wedges, especially during batch wedge scraping, where frequent tool adjustments significantly reduce operational efficiency.

[0004] Therefore, in order to avoid damage and improve efficiency, this utility model proposes a tool that can efficiently improve the scraping efficiency to solve the above problems. Utility Model Content

[0005] This invention provides a tool that efficiently improves scraping efficiency, thereby solving at least one of the aforementioned technical problems.

[0006] The technical solution adopted in this utility model is: a tool that can efficiently improve the efficiency of scraping and grinding.

[0007] In a preferred embodiment, the device includes a main rod for assembling and disassembling a wedge and a counterweight fitted over the main rod. The end of the main rod away from the counterweight is provided with an L-shaped connector. One end of the L-shaped connector, which is connected to the positioning pin of the wedge, is provided with an auxiliary component, and the other end is provided with a snap-fit ​​component that mates with the main rod. A limiting block is provided at the end of the main rod away from the L-shaped connector. The counterweight slides along the axial direction of the main rod and generates an axial impact by striking the limiting block.

[0008] In a preferred embodiment, the snap-fit ​​element is a barbed protrusion, and the inner wall of the main rod near the L-shaped connector is provided with a barbed end that matches the barbed protrusion, so that the main rod and the L-shaped connector can be quickly connected through the cooperation of the two.

[0009] In a preferred embodiment, the snap-fit ​​component consists of symmetrically arranged snap-fit ​​tenons, with a tension spring connecting the snap-fit ​​tenons, and a locking slot is provided at one end of the main rod near the L-shaped connector.

[0010] In a preferred embodiment, the snap-fit ​​component is a screw rod, and the inner wall of the main rod near the L-shaped connector is provided with an internal thread that mates with the screw rod.

[0011] In a preferred embodiment, the auxiliary component is a C-shaped hoop, which is an elastic component with anti-slip texture on the inner side, and its opening size is adapted to the diameter of the wedge positioning pin.

[0012] In a preferred embodiment, the end of the L-shaped connector connected to the wedge positioning pin has a movable groove, the auxiliary component is a limiting block extending into the movable groove, and a telescopic spring is provided between one side of the limiting block and the bottom of the movable groove.

[0013] In a preferred embodiment, the outer surface of the main rod has multiple limiting grooves extending along the axial direction of the main rod, and the inner wall of the counterweight is provided with a locking block that cooperates with the limiting grooves.

[0014] In a preferred embodiment, the hammer is connected to an easy-to-grip operating handle, and the outer surface of the handle is provided with anti-slip texture.

[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] 1. In a preferred embodiment of this utility model, the tool achieves rapid assembly and disassembly of the wedge through the design of an L-shaped connector. The convenient connection between the L-shaped connector and the main rod, combined with the auxiliary components' secure fixation of the wedge's positioning pin, and the axial impact force generated by the sliding impact of the counterweight along the main rod against the limiting stop, efficiently transmits force to the wedge, thus completing the assembly and disassembly operation. The snap-fit ​​between the L-shaped connector and the main rod ensures the stability of force transmission, while the auxiliary components guarantee the reliability of the connection between the tool and the wedge's positioning pin. The sliding impact of the counterweight provides sufficient power for assembly and disassembly.

[0017] 2. As a preferred embodiment of this utility model, when the snap-fit ​​component is a barbed protrusion and the main rod is provided with a matching barbed retraction, the barbed protrusion has an outwardly inclined protruding structure, and the barbed retraction is a corresponding inwardly inclined tightening structure on the inner wall. When the two come into contact, the protrusion can slide into the retraction in the direction of ...

[0018] Furthermore, when the snap-fit ​​parts are symmetrically arranged snap-fits with tension springs connecting them, and the main rod has a locking slot, the symmetrical snap-fits, under the action of the tension springs, form a precise engagement with the locking slot on the main rod. This ensures both axial and radial stability after connection and enables convenient operation of "one push to connect, one press to disassemble," ensuring that there will be no loosening or falling off under impact loads. This allows for efficient assembly and disassembly of the wedge, and the quick connection and secure locking of the main rod and L-shaped connector are achieved through the cooperation of the snap-fits, tension springs, and locking slots.

[0019] In addition, when the snap-fit ​​part is a screw rod and the main rod has a matching internal thread, the main rod and the L-shaped connector can be detachably fixedly connected by the thread meshing principle. The axial preload is generated by the inclined contact of the thread teeth, which not only ensures the structural rigidity after connection, but also prevents loosening during impact through the self-locking characteristic of the thread, ensuring efficient force transmission, thereby achieving efficient assembly and disassembly of the wedge.

[0020] As a preferred embodiment of this utility model, the continuous clamping force is generated by utilizing the elastic deformation characteristics of the C-shaped hoop, and the C-shaped hoop also has a certain size adaptability, which ensures the tightness of the connection between the positioning pin and the L-shaped connector. The anti-slip texture on the inner side increases the friction between the tool and the positioning pin, avoiding slippage or misalignment caused by instantaneous force, and ensuring a stable connection between the tool and the wedge.

[0021] Furthermore, when the auxiliary component is a limiting block that extends into the movable groove and the limiting block is equipped with a telescopic spring, the L-shaped connector and the wedge positioning pin are locked together through the principle of elastic telescopic movement. The elastic force of the telescopic spring forms a locking structure at the end of the L-shaped connector connected to the wedge positioning pin. When the wedge positioning pin is engaged with the L-shaped connector, the telescopic spring pushes the limiting block out of the movable groove, locking the L-shaped connector and the wedge positioning pin together. This prevents the wedge positioning pin from accidentally disengaging from the L-shaped connector. When separation is required, applying a reverse force to the limiting block compresses the telescopic spring, causing the limiting block to retract into the movable groove and release the engagement with the positioning pin, thus enabling flexible assembly and disassembly.

[0022] 4. In a preferred embodiment of this utility model, the axial limiting groove on the outer surface of the main rod and the locking block on the inner wall of the hammer form a sliding fit, which not only restricts the hammer to slide only along the axial direction, but also prevents the hammer from rotating circumferentially relative to the main rod. The axial guiding and circumferential limiting principle is used to achieve stable sliding of the hammer along the main rod, ensuring that the force-bearing surface of the hammer is always facing the stop block when it hits the limiting block, avoiding impact deviation or energy loss caused by rotation, and improving the utilization efficiency of impact force.

[0023] 5. As a preferred embodiment of this utility model, the handle is designed to provide grip stability, and the anti-slip texture on the outer surface increases the static friction between the palm and the handle. This not only makes it easier for the operator to control the sliding speed and force of the hammer, but also prevents slippage during operation, ensuring that the impact action is precise and controllable, and improving the convenience and stability of hammer operation.

[0043] Example 1

[0044] A preferred embodiment, such as Figure 1As shown, a tool for efficiently improving scraping efficiency includes a main rod 1 for disassembling and assembling a wedge and a counterweight 2 sleeved on the main rod 1. The end of the main rod 1 away from the counterweight 2 is provided with an L-shaped connector 3. The end of the L-shaped connector 3 connected to the wedge positioning pin 4 is provided with an auxiliary part 31, and the other end is provided with a snap-fit ​​part 32 that cooperates with the main rod 1. The end of the main rod 1 away from the L-shaped connector 3 is provided with a limiting block 11. The counterweight 2 slides along the axial direction of the main rod 1 and generates an axial impact by hitting the limiting block 11. During the installation of the wedge, the end of the L-shaped connector 3 with the snap-fit ​​32 is connected to the end of the main rod 1 near the L-shaped connector 3. The snap-fit ​​32 enables a quick and stable connection between the main rod 1 and the L-shaped connector 3, ensuring that the main rod 1 and the wedge form a coaxial force-bearing structure and avoiding lateral force during impact. The end of the L-shaped connector 3 with the auxiliary part 31 is connected to the wedge positioning pin 4. The auxiliary part 31 can enhance the connection stability. At this time, the operator slides the hammer 2 along the axis of the main rod 1, using the weight of the hammer 2 and the sliding speed to accumulate kinetic energy. When the hammer 2 slides to the end of the main rod 1, it is quickly slid in the opposite direction to strike the limit stop 11 at high speed. The kinetic energy is instantly transferred to the wedge positioning pin 4 through the main rod 1 and the L-shaped connector 3, and converted into an axial impact force on the wedge. Depending on the tightness of the wedge, the impact force can be adjusted by controlling the sliding distance and speed of the hammer 2 to achieve precise disassembly and assembly. Compared to traditional tools, the L-shaped connector 3 design can adapt to the disassembly and assembly needs of wedges of different specifications, reducing the time of wedge extraction and release. Furthermore, the sliding impact of the counterweight 2 achieves concentrated force transmission, reducing manual labor costs and thus completing the wedge extraction and release operation, greatly improving work efficiency.

[0045] In addition, the hammer 2 is connected to an easy-to-grip operating handle 22. The outer surface of the handle 22 is provided with anti-slip texture. When the operator holds the operating handle 22, the anti-slip texture on the outer surface of the handle 22 makes close contact with the palm, increasing friction and effectively preventing relative slippage between the hand and the handle 22. By holding the handle 22, the operator can more easily control the hammer 2 to slide along the axis of the main rod 1: applying force to push or pull the handle 22 will cause the hammer 2 to slide stably along the main rod 1, avoiding the hammer 2 from deviating due to an unstable grip.

[0046] Example 2

[0047] like Figure 2As shown, a tool that efficiently improves scraping efficiency, differing from Embodiment 1, features a snap-fit ​​component 32 with a barbed protrusion 321. When the inner wall of the main rod 1 near the L-shaped connector 3 has a barbed retraction 12 that matches the barbed protrusion 321, the main rod 1 and the L-shaped connector 3 can be quickly connected through their cooperation. Specifically, it is confirmed that the barbed protrusion 321 on the outer wall of the L-shaped connector 3 is aligned with the barbed retraction 12 on the inner wall of the main rod 1 near the L-shaped connector 3, ensuring that the protrusion and retraction are in the same direction. The operator then places the L-shaped connector into place. One end of the L-shaped connector 3 with the barbed protrusion 321 is axially inserted into the barbed constriction 12 end of the main rod 1. During insertion, due to the mutual guidance between the inclined surfaces of the barbed protrusion 321 and the barbed constriction 12, the barbed protrusion 321 smoothly enters the interior of the main rod 1. When the protrusion is completely slid into the locking position of the constriction, the reverse inclined surface of the protrusion and the reverse inclined surface of the constriction fit tightly together, forming a mechanical self-locking mechanism. Since the two are inclined in opposite directions, when the L-shaped connector 3 is pulled outward, the protrusion is locked tighter and tighter by the constriction, achieving a rigid connection between the main rod 1 and the L-shaped connector 3. Due to the self-locking characteristics of the barbed structure, the contact area and pressure between the two increase with the increase of the impact force during the impact process, ensuring efficient force transmission and preventing the connection from loosening or falling off.

[0048] In addition, such as Figure 3As shown, when the locking element 32 consists of symmetrically arranged tenons 322, with tension springs 323 connecting the tenons 322, and a locking slot 13 is provided at the end of the main rod 1 near the L-shaped connector 3, in its natural state, the symmetrical tenons 322 on the L-shaped connector 3 open outward under the contraction force of the tension springs 323, with the protruding part higher than the outer wall of the connecting end of the L-shaped connector 3, preparing to be engaged with the locking slot 13. When it is necessary to connect the main rod 1 and the L-shaped connector 3, the operator aligns the tenon 322 end of the L-shaped connector 3 with the locking slot 13 position near the end of the main rod 1, ensuring that the tenon 322 and the locking slot 13 are aligned circumferentially, and while axially pushing the L-shaped connector 3, pinches the symmetrically arranged tenons 322 by hand, so that the tenon 322 end is inserted into the main rod 1. During insertion, the inclined guide surface of the latch 322 contacts the inner wall of the main rod 1 and is subjected to radial pressure, forcing the latch 322 to retract inward. The tension spring 323 is compressed, storing elastic potential energy. At this time, the protrusion of the latch 322 temporarily retracts, allowing it to pass smoothly through the non-jamming area 13 of the main rod 1. When the latch 322 moves to the jamming position 13 of the main rod 1, the radial pressure disappears, the tension spring 323 returns to its natural length, and the latch 322 pops outward. The protrusion is precisely embedded in the groove of the jamming position 13, forming a mechanical lock. At this time, the main rod 1 and the L-shaped connector 3 cannot be separated axially or rotated relative to each other circumferentially, completing a rapid connection. Because the engagement area of ​​the latch 322 and the jamming position 13 is large and the tension spring 323 continuously provides preload, there is no relative sliding between the two during the impact, ensuring efficient force transmission and preventing loosening of the connection. For disassembly, the operator simultaneously presses the exposed parts of the symmetrical latches 322, forcing the latches 322 to retract inward against the elastic force of the tension spring 323, causing the protrusion to disengage from the groove of the latch 13. While maintaining the pressing state, the L-shaped connector 3 is pulled out axially, and the end of the latch 322 is pulled out from the main rod 1, completing the disassembly. This design allows for "insertion and engagement" during connection and "pressing and disengagement" during separation, eliminating the need for rotation or auxiliary tools and significantly improving the efficiency of tool loading and unloading.

[0049] In addition, such as Figure 4As shown, when the snap-fit ​​part 32 is a screw rod 324, and the inner wall of the main rod 1 near the L-shaped connector 3 is provided with an internal thread 14 that matches the screw rod 324, align the screw rod 324 on the L-shaped connector 3 with the entrance of the internal thread 14 of the main rod 1 near the L-shaped connector 3, the operator holds the L-shaped connector 3 and makes the two rotate relative to each other. As the rotation proceeds, the external thread of the screw rod 324 is gradually screwed into the internal thread 14 of the main rod 1, the thread teeth mesh with each other, and the axial distance gradually shortens until the two are connected in place. After the connection is in place, a preload is generated between the threaded pairs, so that the main rod 1 and the L-shaped connector 3 form a rigid whole, with no relative displacement in the axial and radial directions, thus achieving a stable connection between the two. The tightness of the connection can be adjusted by controlling the screwing depth. When disassembly is required, the operator rotates the L-shaped connector 3 and the main rod 1 in the opposite direction, causing the external thread of the screw rod 324 to gradually unscrew from the internal thread 14 of the main rod 1. The threads disengage, and after complete unscrewing, the main rod 1 separates from the L-shaped connector 3, restoring the tool to its disassembled state for easy storage or replacement of parts. Due to the self-locking characteristic of the threads, the axial force generated by the impact makes the threaded pair mesh more tightly, preventing loosening or slippage at the connection point and ensuring efficient and stable force transmission.

[0050] Example 3

[0051] like Figure 5 As shown, a tool that efficiently improves scraping efficiency, differing from Embodiment 1, features an auxiliary component 31 that is a C-shaped hoop 311. The C-shaped hoop 311 is an elastic component with anti-slip textures on its inner side, and its opening size is adapted to the diameter of the wedge positioning pin 4. Because the C-shaped hoop 311 is an elastic component made of flexible materials such as silicone, when connecting the tool to the wedge positioning pin 4, the end of the L-shaped connector 3 closest to the positioning pin is aligned with the position to be connected on the positioning pin. The operator applies pressure along the axial direction of the positioning pin, causing one end of the C-shaped hoop 311 to engage in the annular structure of the positioning pin. After engagement, The C-shaped clamp 311 returns to its original shape due to its own elasticity, with the middle part tightly fitting the surface of the wedge positioning pin 4. Its matching opening size ensures the initial fit, while the elastic contraction force further enhances the tightness of the connection. The anti-slip texture on the inner side is in close contact with the surface of the positioning pin, increasing the friction and effectively preventing slippage or detachment during subsequent operations. Through mechanical interlocking and friction, a double lock is formed to ensure that the connection is not loose, completing the reliable connection and fixation of the tool and the wedge. After the operation is completed, the operator applies pressure in the opposite direction along the axial direction of the positioning pin to make the C-shaped clamp 311 disengage from the positioning pin.

[0052] In addition, such as Figure 6As shown, when the L-shaped connector 3 has a movable groove 15 at one end connected to the wedge positioning pin 4, and the auxiliary component 31 is a limiting block 312 extending into the movable groove 15, with a telescopic spring 313 between one side of the limiting block 312 and the bottom of the movable groove 15, in the process of connecting the tool to the wedge positioning pin 4, the end of the L-shaped connector 3 with the movable groove 15 and the limiting block 312 is aligned with the wedge positioning pin 4, and the limiting block 312 is pushed. As the pushing force increases, the limiting block 312 is pressured into the movable groove 15. The telescopic spring 313 contracts and compresses. When the limiting block 312 is fully inserted into the space formed by the movable groove 15, the L-shaped connector 3 is engaged in the annular structure of the wedge positioning pin 4. At this time, the elastic force of the telescopic spring 313 pushes the limiting block 312 tightly against the surface of the positioning pin. When the L-shaped connector 3 is inserted to a certain depth into the annular structure, the telescopic spring 313 releases pressure, pushing the limiting block 312 out of the movable groove 15. At this time, the wedge positioning pin 4 and the L-shaped connector 3 form a locking structure, creating a mechanical limit. At this time, the L-shaped connector 3 and the positioning pin cannot be separated axially and are radially fixed, completing the connection. When disassembly is required, the operator can push the limiting block 312 again. After the limiting block 312 is fully inserted into the space formed by the movable groove 15, the L-shaped connector 3 can be pulled out of the annular structure of the wedge positioning pin 4, releasing the engagement with the positioning pin. The automatic telescopic movement driven by the spring achieves "insertion equals engagement, press equals separation," simplifying the connection steps and adapting to the needs of rapid operation.

[0053] Example 4

[0054] like Figure 7As shown, a tool for efficiently improving scraping efficiency is presented. Unlike embodiment 1, the outer surface of the main rod 1 has multiple limiting grooves 16 extending axially along the main rod 1, symmetrically distributed to balance the force. The inner wall of the hammer 2 is provided with a locking block 21 that matches the limiting groove 16, the size of the locking block 21 matching the groove width. After the hammer 2 is inserted into the main rod 1, the locking block 21 is fully embedded in the limiting groove 16, forming a sliding motion. When disassembly is required, the operator can push or pull the hammer 2 axially along the main rod 1. At this time: the limiting groove 16 restricts the radial displacement of the hammer 2 through the locking block 21, ensuring that the hammer 2 always moves along the axis of the main rod 1, avoiding wobbling or jamming due to center of gravity shift; the locking block 21 contacts the side of the limiting groove 16, preventing the hammer 2 from rotating around the main rod 1, ensuring that the impact surface of the hammer 2 always remains horizontal or perpendicular to the axis, guaranteeing accurate impact direction. The cooperation of multiple limiting grooves 16 with corresponding locking blocks 21 can distribute the force, preventing excessive wear of a single structure due to friction or impact, and extending its service life. During the impact process, the constraint of the limiting grooves 16 on the locking blocks 21 can also prevent the hammer 2 from "bouncing" and deviating due to inertia, ensuring the stability of subsequent multiple impact operations. For example, during continuous striking, the hammer 2 can quickly reset and slide along its original trajectory. Compared with a non-guided sliding structure, the cooperation of the limiting grooves 16 and locking blocks 21 significantly reduces the shaking and deviation of the hammer 2 during sliding, improves the impact accuracy, and avoids the dispersion of impact energy caused by the rotation or deviation of the hammer 2, allowing more kinetic energy to be converted into effective impact force on the wedge, thus improving the efficiency of scraping operations. Any aspects not described in this utility model can be achieved by adopting or referencing existing technologies.
