DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Please also read Figures 1 to 9 Now, a rock drilling tool ball tooth installation device provided by the present invention is described. The rock drilling tool ball tooth installation device comprises a workbench 1, an intermediate frequency heating ring 2, a plurality of guide barrels 3 and an operating panel 4; the workbench 1 has a positioning structure for placing a drill bit 5; the intermediate frequency heating ring 2 is located directly above the positioning structure; the intermediate frequency heating ring 2 is installed on a heating frame (not shown in the figure), and the heating frame is located on one side of the workbench 1; a plurality of guide barrels 3 correspond to the mounting holes 51 on the drill bit 5 one by one; each guide barrel 3 is provided with a plurality of strip grooves 31 near the bottom, and a clamping plate 32 is provided between adjacent strip grooves 31, and a plurality of clamping plates 32 have a preset taper to clamp the ball teeth 6 in the guide barrel 3; the operating panel 4 is connected to the plurality of guide barrels 3; wherein, the ball tooth installation device further comprises a pushing mechanism 7, and when the guide barrel 3 is aligned with the corresponding mounting holes 51 on the drill bit 5, the pushing mechanism 7 can push the ball teeth 6 in the guide barrel 3 so that the ball teeth 6 enter the mounting holes 51. By providing the operating panel 4 , the plurality of material guide barrels 3 can be formed into a whole, so that the plurality of material guide barrels 3 are aligned with the mounting holes 51 on the drill bit 5 ; the operating panel 4 also facilitates the operator to take and place the material guide barrels 3 .

[0020] The present invention provides a rock drilling tool ball tooth installation device. Compared with the prior art, when the ball tooth 6 is hot-inserted onto the drill bit 5, the drill bit 5 is placed on the positioning structure, and the installation hole 51 on the drill bit 5 is located in the area surrounded by the medium frequency heating ring 2. The drill bit 5 is heated by the medium frequency heating ring 2 to make the drill bit 5 reach the hot-insertion temperature; during the heating process of the drill bit 5, the operator places the ball tooth 6 into the material guide barrel 3. After the drill bit 5 reaches the hot-insertion temperature, the operator places the material guide barrel 3 onto the drill bit 5 to make the material guide barrel 3 correspond to the installation hole 51 one by one; the push structure provides thrust to the ball tooth 6 in the material guide barrel 3, so that the ball tooth 6 in the material guide barrel 3 can enter the installation hole 51 of the drill bit 5; through the above-mentioned configuration of the present application, there is no need for the operator to frequently place the ball tooth 6 on the heated drill bit 5, which can reduce safety hazards.

[0021] It should be noted that the above-mentioned installation process of the present application is relatively fast, and the material of each material guide barrel 3 is a heat-insulating material, so the temperature rise of the material guide barrel 3 is not high; the workbench 1 is provided with a material trough 11 for placing the ball teeth 6, and the material trough 11 is separated by a partition with a water trough 12, and the water trough 12 is used to cool the contact position between the material guide barrel 3 and the drill bit 5; after the ball teeth 6 are installed on the drill bit 5, the bottom of the material guide barrel 3 is placed in the water trough 12, which can cool the bottom of the material guide barrel 3.

[0022] For example, after the ball tooth 6 enters the mounting hole 51 of the drill bit 5, the material guide tube 3 is removed from the drill bit 5; in order to ensure that the ball tooth 6 can be installed in place, the operator can knock the ball tooth 6 with a copper hammer to ensure the installation effect, and then the operator clamps out the drill bit 5 with a clamp, and places the drill bit 5 on a cooling rack to allow the drill bit 5 to cool naturally.

[0023] In addition, since the strip groove 31 is provided at the bottom of the guide barrel 3, the bottom of the guide barrel 3 can be divided into a plurality of clamping plates 32. By setting the plurality of clamping plates 32 in a form of a preset taper, after the ball tooth 6 is placed into the guide barrel 3, the plurality of clamping plates 32 can play a role of circumferential limit on the ball tooth 6, thereby reducing the situation where the ball tooth 6 slides out of the guide barrel 3; when the ball tooth 6 in the guide barrel 3 is pushed by the pushing mechanism 7, the clamping plates 32 can be elastically deformed, so that the ball tooth 6 can pass through the area surrounded by the clamping plates 32 and enter the mounting hole 51 of the drill bit 5; since the clamping plates 32 can be elastically deformed, after the ball tooth 6 is installed on the drill bit 5, the guide barrel 3 can be removed from the drill bit 5. The hardness of the clamping plates 32 is lower than that of the ball tooth 6, so when there is relative movement between the ball tooth 6 and the clamping plates 32, the situation where the ball tooth 6 is scratched can be reduced.

[0024] In some embodiments, Figures 1 to 9As shown, the operating disk 4 is connected to the top of the material guide cylinder 3, and the operating disk 4 has placement holes 41 corresponding to the material guide cylinder 3, and the placement holes 41 are through holes; the pushing mechanism 7 can push the ball tooth 6 by air pressure so that the ball tooth 6 enters the mounting hole 51 of the drill bit 5; the pushing mechanism 7 can also push the ball tooth 6 by the piston rod of the cylinder so that the ball tooth 6 enters the mounting hole 51 of the drill bit 5.

[0025] Exemplarily, when the pushing mechanism 7 pushes the ball tooth 6 by air pressure, the pushing mechanism 7 includes a pressure plate 71, and the pressure plate 71 has an air cavity 711 inside; the top of the pressure plate 71 is connected to the pressurized gas through an air pipe, and the bottom of the pressure plate 71 has an air outlet 712 aligned one by one with the placement hole 41; when the pressurized gas is connected to the air cavity 711, the pressurized gas can enter the material guide barrel 3 through the air outlet 712, and then push the ball tooth 6 in the material guide barrel 3, so that the ball tooth 6 enters the mounting hole 51 of the drill bit 5.

[0026] Exemplarily, when the pushing mechanism 7 pushes the ball gear 6 through the piston rod of the cylinder, the pushing mechanism 7 includes a pressure plate 71 and a plurality of pushing cylinders 72; the pressure plate 71 has avoidance holes aligned with the placement holes 41; the plurality of pushing cylinders 72 correspond to the avoidance holes one by one; each pushing cylinder 72 is fixedly connected to the top of the pressure plate 71; through the extension of the piston rod of the pushing cylinder 72, the piston rod can be extended into the guide barrel 3, and the ball gear 6 in the guide barrel 3 can be pushed, so that the ball gear 6 enters the mounting hole 51 of the drill bit 5. A push plate is fixed to the push end of the piston rod of the pushing cylinder 72, and the hardness of the push plate is lower than that of the ball gear 6, so as to reduce the situation where the push plate scratches the ball gear 6.

[0027] Exemplarily, a positioning structure is provided between the pressure plate 71 and the operating disk 4, so that the air outlet holes 712 on the pressure plate 71 correspond one-to-one with the placement holes 41 on the operating disk 4, and the pressure plate 71 and the operating disk 4 can be upper-limited in the height direction; the positioning structure includes a positioning rod 73, and the positioning rod 73 is connected to the bottom of the pressure plate 71; the other end of the positioning rod 73 has a positioning ball 74, and the diameter of the positioning ball 74 is larger than the diameter of the positioning rod 73; wherein, the top of the operating disk 4 has an arc groove 42 that slidably cooperates with the positioning rod 73, one end of the arc groove 42 has a socket 43 for inserting the positioning ball 74, and the side wall of the arc groove 42 also has an avoidance groove 44 for the sliding of the positioning ball 74. After the ball teeth 6 are placed into the guide barrel 3, the pressure plate 71 is placed on the operating disk 4, and the positioning ball 74 is plugged into the socket 43, and then the pressure plate 71 is rotated circumferentially so that the positioning ball 74 slides into the avoidance groove 44; after the pressure plate 71 is rotated into place, the positioning ball 74 contacts the end of the avoidance groove 44, and the air outlet 712 on the pressure plate 71 is connected to the placement hole 41 on the operating disk 4, or the avoidance hole on the pressure plate 71 is connected to the placement hole 41 on the operating disk 4. Through the above arrangement, it is convenient to locate the position between the pressure plate 71 and the operating disk 4 in the height direction. The axis of the arc groove 42 coincides with the axis of the operating disk 4.

[0028] It should be noted that the guide barrel 3 is placed on the workbench 1, and then the ball gear 6 is placed in the guide barrel 3; after the ball gear 6 is placed in the guide barrel 3, the pressure plate 71 can be connected to the operating disk 4; the operating disk 4 can also be placed on the drill bit 5, and then the pressure plate 71 is connected to the operating disk 4. In order to reduce the contact time between the guide barrel 3 and the drill bit 5, it is preferred to connect the pressure plate 71 to the operating disk 4 after the guide barrel 3 is placed in the ball gear 6.

[0029] In some embodiments, Figures 1 to 9 As shown, the operating disk 4 has a first heat-insulating handle 45, and the pressure plate 71 has a second heat-insulating handle 75; wherein, one side of the first heat-insulating handle 45 has a socket 451, and the two opposite sides of the socket 451 are arc surfaces, and the axis of the arc surface coincides with the axis of the operating disk 4; the positioning structure also includes a plug plate 76 connected to the second heat-insulating handle 75, and the plug plate 76 has a curved section 761 that is plugged into and matched with the socket 451; the two opposite sides of the curved section 761 are arc surfaces, and the axis of the arc surface coincides with the axis of the operating disk 4.

[0030] It should be noted that, by providing the first insulation handle 45 and the second insulation handle 75, it is convenient for the operator to rotate the pressure plate 71 and then connect the pressure plate 71 to the operating disk 4; by providing the socket 451 on the first insulation handle 45 and the plug plate 76 on the second insulation handle 75, and by the bending section 761 of the plug plate 76 being plugged into the socket 451, the height position of the pressure plate 71 and the operating disk 4 can be further limited.

[0031] In some embodiments, Figures 1 to 9 As shown, the bottom of the operating disk 4 has a plurality of positioning components 46 , and each positioning component 46 is plugged into and matched with the discharge groove 52 on the outer peripheral wall of the drill bit 5 to position the operating disk 4 circumferentially.

[0032] It should be noted that, by providing a positioning component 46 at the bottom of the operating panel 4 and by plugging the positioning component 46 into the discharge groove 52 on the outer wall of the drill bit 5, the relative positions of the operating panel 4 and the drill bit 5 can be positioned, so that the material guide cylinder 3 and the mounting holes 51 on the drill bit 5 correspond one to one, which facilitates pushing the ball teeth 6 on the material guide cylinder 3 into the mounting holes 51 of the drill bit 5.

[0033] In some embodiments, Figures 1 to 9 As shown, the positioning structure includes a positioning plate 8, on which a positioning column 81 is provided for plugging with the drill bit 5; wherein the positioning plate 8 has the freedom to slide along the height direction, and when the drill bit 5 is plugged with the positioning column 81, the mounting hole 51 of the drill bit 5 is located above the medium frequency heating ring 2; the drill bit 5 descends with the positioning plate 8 so that the mounting hole 51 of the drill bit 5 is located in the area surrounded by the medium frequency heating ring 2; a lifting cylinder (not shown in the figure) is connected to the bottom of the workbench 1, and the piston rod of the lifting cylinder passes through the workbench 1 and is connected to the positioning plate 8.

[0034] It should be noted that the positioning column 81 is located directly below the medium frequency heating ring 2; before placing the drill bit 5 on the positioning column 81, the piston rod of the lifting cylinder is extended to lift the positioning plate 8 to a high position, and then the drill bit 5 is plugged into the positioning column 81; the piston rod of the lifting cylinder is retracted, so that the positioning plate 8 and the drill bit 5 are lowered together, and at this time, the mounting hole 51 of the drill bit 5 is located in the area surrounded by the medium frequency heating ring 2, which is convenient for the medium frequency heating ring 2 to heat the mounting hole 51 of the drill bit 5. After the ball tooth 6 is installed on the drill bit 5, the lifting cylinder pushes the positioning plate 8 upward so that the mounting hole 51 of the drill bit 5 is located above the medium frequency heating ring 2. At this time, the operator can remove the drill bit 5 from the positioning plate 8 by tools.
