Description

Technical Field

[0001] This utility model relates to the field of cable winding technology, and in particular to a winding bracket for a grinding wheel machine cable. Background Technology

[0002] A handheld grinder is a type of handheld power tool primarily used for grinding operations in machinery manufacturing and repair. In shipbuilding, boiler manufacturing, chemical machinery, and various other machinery manufacturing and repair work, it is used for metalworking operations such as deburring, chamfering, grinding, removing burrs and oxide scale, grinding welds, sanding, and polishing. When using a handheld grinder in the operating room, due to the distance between the operating position and the power source, the grinder needs to be connected to the power source via a cable. When storing the handheld grinder, the cable must be neatly stored on a stand.

[0003] Existing handheld grinder stands are time-consuming and cumbersome to retract manually when using the cable, which is of a certain length. Furthermore, since one end of the cable needs to be connected to a power source, the plug at the cable end can shift during retraction, potentially causing a circuit interruption. Additionally, the cable end is pressed tightly against the inside of the winding reel, making it inconvenient to connect to an external power source.

[0004] Therefore, it is necessary to invent a winding bracket for grinding wheel machine cables to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a winding bracket for grinding machine cables, which allows the horizontal limiting rod to rotate with the winding disc, thereby achieving the purpose of automatically storing the extended cable on the winding disc and improving the winding efficiency of grinding machine cables.

A horizontal limiting rod is rotatably connected to the support vertical rod via a bearing, and a limiting prism is integrally provided on the horizontal limiting rod. A winding disc is sleeved on the outer side of the limiting prism and the horizontal limiting rod. The limiting prism and the horizontal limiting rod coaxially drive the winding disc to rotate circumferentially.

[0008] One end of the horizontal limiting rod is fixedly connected to a driven tooth, a limiting cylinder is fixedly connected to the supporting vertical rod, an electric push rod is fixedly connected inside the limiting cylinder, and the output end of the electric push rod is drivenly connected to a drive motor. The output shaft of the drive motor is drivenly connected to a drive tooth, so that the drive tooth and the driven tooth can switch between an engaged state and a disengaged state.

[0009] A conductive slip ring mechanism is installed between the support rod and the winding reel, so that the extension cable stored in the winding reel is electrically connected to the cable of the grinding wheel. The winding reel has a positioning hole for the extension cable to pass through, and multiple binding holes are opened on both sides of the positioning hole. A self-locking nylon cable tie is provided in two adjacent binding holes to bind the end of the extension cable.

[0010] Preferably, the conductive slip ring mechanism includes a terminal block and an annular contact plate, wherein the terminal block is installed on the outside of the winding reel, the annular contact plate is sleeved on the outer ring of the bearing, and the terminal block is provided with a conductive contact rod, the end of which is movably attached to the annular groove of the annular contact plate, so that the terminal block is electrically connected to the annular contact plate through the conductive contact rod.

[0011] The terminal block is electrically connected to the end of the cable passing through the positioning hole, and the connection end of the annular terminal block is electrically connected to a plug for connecting to a power source.

[0012] The winding bracket also includes a controller and a relay. The relay is connected in series in the connection circuit between the ring-shaped contact plate and the plug. The electric push rod and the drive motor are both connected in parallel in the connection circuit between the ring-shaped contact plate and the plug. The electric push rod, the drive motor and the relay are all electrically connected to the controller.

[0013] The square cross-section of the limiting prism matches the axial insertion hole of the winding disc, and the side length of the square cross-section of the limiting prism is equal to the diameter of the horizontal limiting rod.

[0014] Preferably, the two ends of the horizontal limiting rod extend out of both sides of the winding reel, and a buffer washer is slidably sleeved on the outer side of the horizontal limiting rod and between the winding reel and the bearing, and a nut is threaded onto the end of the horizontal limiting rod away from the supporting vertical rod.

[0015] Preferably, the upper end of the supporting vertical rod is welded with a support member for supporting the grinding wheel, and the support member has a C-shaped structure.

[0016] Preferably, a protective cover is fixed to the outer surface of the support rod, and the protective cover covers the outside of the drive tooth and the driven tooth.

[0017] Preferably, the top of the supporting vertical rod is equipped with a bracket assembly for temporary support of the extension cable. The bracket assembly includes a right-angle plate, and at least two cantilever beams are slidably arranged through one side of the right-angle plate. The outer ends of the multiple cantilever beams are fixedly connected to a baffle.

[0020] This utility model has the following beneficial effects:

[0021] By controlling the output end of the electric push rod to drive the motor, the drive teeth and driven teeth are further engaged. At this time, the automatic winding mode is adopted. The output shaft of the drive motor drives the drive teeth to engage with the driven teeth, thereby causing the horizontal limit rod to rotate with the winding disc, achieving the purpose of automatically winding the extended cable onto the winding disc. This improves the efficiency of cable winding of the grinding wheel. The process is simple and quick, requiring no manual rotation or traction, thus reducing the labor intensity of the workers.

[0022] 2. Through the conductive slip ring mechanism composed of terminals, conductive contact rods, and annular contact plates, the terminals are electrically connected to the annular contact plates via the conductive contact rods.

[0037] like Figure 1-6 As shown, a winding bracket for a grinding machine cable includes a support vertical rod 1. Multiple support ribs 2 arranged in a circular array are welded to the bottom outer side of the support vertical rod 1. A horizontal limiting rod 17 is rotatably connected to the support vertical rod 1 via a bearing 3. A limiting prism 18 is integrally provided on the horizontal limiting rod 17. A winding disc 4 is sleeved on the outer side of both the limiting prism 18 and the horizontal limiting rod 17. The limiting prism 18 and the horizontal limiting rod 17 coaxially drive the winding disc 4 to rotate circumferentially. The end of a longer extension cable is relatively fixed on the winding disc 4 and rotated, thereby enabling the winding and storage of cables used when the grinding machine is operating remotely.

[0038] A driven tooth 5 is fixedly connected to one end of a horizontal limiting rod 17. A limiting cylinder 19 is fixedly connected to the supporting vertical rod 1. An electric push rod 20 is fixedly connected inside the limiting cylinder 19, and a drive motor 6 is driven to the output end of the electric push rod 20. A drive tooth 7 is driven to the output shaft of the drive motor 6, allowing the drive tooth 7 and the driven tooth 5 to switch between an engaged state and a disengaged state. After the drive motor 6 is energized, its output shaft engages with the driven tooth 5 through the drive tooth 7, causing the horizontal limiting rod 17 to rotate with the winding reel 4. This allows the extension cable to be wound around the outside of the winding reel 4, improving the efficiency of cable winding in the grinding machine.

[0039] A conductive slip ring mechanism is installed between the support rod 1 and the winding reel 4, enabling the extension cable stored in the winding reel 4 to be electrically connected to the cable of the grinding wheel. The winding reel 4 has a positioning hole 41 for the extension cable to pass through, and multiple binding holes 42 are located on both sides of the positioning hole 41. Self-locking nylon cable ties are installed in adjacent binding holes 42 to bind the end of the extension cable. A rotatable conductive slip ring mechanism is installed between the bearing 3 and the winding reel 4 to prevent twisting due to the fixed terminal when the winding reel 4 rotates with the grinding wheel cable, thereby improving the stability of the circuit connection.

[0040] Specifically, in the above technical solution, the conductive slip ring mechanism includes a terminal block 8 and an annular contact plate 10. The terminal block 8 is installed on the outside of the winding reel 4, and the annular contact plate 10 is sleeved on the outer ring of the bearing 3. A conductive contact rod 9 is provided on the terminal block 8, and the end of the conductive contact rod 9 is movably fitted into the annular groove of the annular contact plate 10, so that the terminal block 8 is electrically connected to the annular contact plate 10 through the conductive contact rod 9. The terminal block 8 is electrically connected to the end of the cable passing through the positioning hole 41, and the connection end of the annular contact plate 10 is electrically connected to a plug 13 for connecting to a power source. The terminal block 8 is electrically connected to the annular contact plate 10 through the conductive contact rod 9, which makes it easy for the conductive contact rod 9 to maintain electrical connection within the annular contact plate 10 when the winding reel 4 rotates. This solves the problem of cable twisting caused by the fixed terminal block when the winding reel 4 is winding the grinding wheel cable, and improves the safety of the grinding wheel cable winding.

[0041] like Figure 7 As shown, the winding bracket also includes a controller 12 and a relay 21. The relay 21 is connected in series in the connection circuit between the annular contact plate 10 and the plug 13. The electric push rod 20 and the drive motor 6 are both connected in parallel in the connection circuit between the annular contact plate 10 and the plug 13. The electric push rod 20, the drive motor 6 and the relay 21 are all electrically connected to the controller 12. The controller 12 can control the relay 21 to open / close, realize the overall circuit control, and also realize the sending of control commands for the electric push rod 20 and the drive motor 6.

[0042] The square cross-section of the limiting prism 18 matches the axial insertion hole of the winding disc 4, and the side length of the square cross-section of the limiting prism 18 is equal to the diameter of the horizontal limiting rod 17.

[0043] Specifically, in the above technical solution, the two ends of the horizontal limiting rod 17 extend outwards from both sides of the winding reel 4. A buffer washer 22 is slidably sleeved on the outer side of the horizontal limiting rod 17 and between the winding reel 4 and the bearing 3. A nut 23 is threadedly sleeved on the end of the horizontal limiting rod 17 away from the supporting vertical rod 1. The buffer washer 22 is made of a flexible material, such as rubber.

[0044] Specifically, in the above technical solution, a support member 14 for supporting the grinding wheel is welded to the upper end of the supporting vertical rod 1, and the support member 14 has a C-shaped structure. This facilitates the support of the grinding wheel.

[0045] Specifically, in the above technical solution, a protective cover 11 is fixed on the outer surface of the supporting vertical rod 1, and the protective cover 11 covers the outside of the driving tooth 7 and the driven tooth 5.

[0046] Specifically, in the above technical solution, a bracket assembly 15 for temporary support of the extension cable is installed at the top of the support rod 1. The bracket assembly 15 can temporarily wrap the cable and adjust the storage space of the cable to facilitate subsequent storage, avoid cable tangling, facilitate grinding work, and speed up work efficiency.

[0047] The bracket assembly 15 includes a right-angle plate 151. At least two cantilever beams 152 are slidably disposed through one side of the right-angle plate 151. A baffle 153 is fixedly connected to the outer ends of the cantilever beams 152 on both sides of the right-angle plate 151. Piston sleeves 154 are fitted onto the outer sides of the cantilever beams 152, such as rubber. The piston sleeves 154 are fitted onto the outer sides of the cantilever beams 152 and limit the movement of the cantilever beams 152 through friction, thereby adjusting the load-bearing inner diameter of the cantilever beams 152 and the baffle 153, and enabling rapid positioning.

[0048] Specifically, in the above technical solution, a through hole is provided at the outer edge of one end of the winding disc 4, and a ring 24 is fixedly connected to the outer edge of the through hole on the outer side of the winding disc 4. A rotating handle 16 is inserted into the ring 24 and the through hole. This allows for manual rotation of the winding disc 4 via the rotating handle 16, enabling the winding of the grinding wheel cable to be performed even when the power is off. Furthermore, in manual mode, the driving gear 7 and the driven gear 5 are separated, so rotating the winding disc 4 will not interfere with the drive motor 6.

[0049] Specifically, in the above technical solution, a cylindrical groove is provided at the bottom axis of the support rod 1, and a cylindrical positioning rod 25 is movably installed in the cylindrical groove. A base plate 26 is welded to the bottom end of the cylindrical positioning rod 25. An ear plate 27 is fixedly connected to the support rib plate 2, and the ear plate 27 and the base plate 26 are limited and fixed by abutting bolts 28. This design allows for fine adjustment of the winding angle of the winding reel 4, facilitating the pulling out of the cable in different directions and the use of a grinding wheel, and also allows for convenient fixing of the support rod 1.

[0050] When using the winding bracket provided by this utility model, the end of the grinding wheel extension cable is inserted into the positioning hole 41, and a self-locking nylon cable tie is used to pass through the binding hole 42 to fix the end of the extension cable relative to the winding reel 4. At this time, the end of the extension cable is further electrically connected to the terminal 8, and the terminal 8 is electrically connected to the annular terminal contact plate 10 through the conductive contact rod 9. The output end of the electric push rod drives the drive motor, further making the drive teeth and driven teeth mesh. At this time, the automatic storage mode is adopted. The output end of the electric push rod 20 pushes the drive motor 6, and its output shaft drives the drive teeth 7, making them mesh with the driven teeth 5. The horizontal limit rod 17 rotates the winding reel 4. At this time, the conductive contact rod 9 can maintain electrical connection within the annular terminal contact plate 10, and the end of the extension cable can be stably wound around the outside of the winding reel 4.

[0051] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and alterations to these embodiments without departing from the principles and spirit of this utility model will still fall within the protection scope of this utility model.
