Description

Technical Field

[0001] This utility model relates to the field of auxiliary processing tools for hydraulic supports, specifically, it relates to a tooling for drilling inclined holes in a hydraulic support radial arm. Background Technology

[0002] After the hydraulic support top beam structure is welded, a radial drilling machine drills a beveled hole to penetrate the lower sleeve. Because the sleeve hole is deep, a long drill bit is required. To prevent drill bit slippage and ensure positioning accuracy, a process step needs to be spot-welded onto the beveled surface to provide a vertical support surface. Currently, the process step is welded onto the drilled surface to provide a vertical surface. After the hole is drilled, the process step needs to be removed, and then the workpiece surface needs to be ground. This process easily damages the base material, and each beveled surface at different angles requires a large amount of material.

[0003] Utility model patent CN221159400U discloses a bevel drilling positioning device, including an adjusting table, an adjusting bracket, a slider frame, a guide rail, and a hinged slider frame. The lower front end of the adjusting table has a hinge, which is hinged to the hinged slider via a hinge shaft. The adjusting table can rotate around the hinge shaft to adjust the elevation angle. The lower rear end of the adjusting table has an adjusting bracket for fixing the adjusting table. The adjusting bracket is connected to the slider frame via fixing screws, fixing the adjusting table and the slider frame together. The slider frame and the hinged slider frame cooperate with the guide rail, allowing them to slide and adjust on the guide rail. When the adjusting table rotates around the hinge shaft to adjust the elevation angle, the fixing screws in the adjusting bracket are tightened to connect and fix it to the slider frame, forming a worktable with an inclined elevation angle between the adjusting table and the guide rail. A workpiece fixed on the upper surface of the adjusting table will then have an inclined angle. This bevel drilling positioning device adjusts the elevation angle of the workpiece through the adjusting table, making the bevel of the workpiece perpendicular to the drill bit, thus facilitating bevel drilling. However, the structure disclosed in this inclined drilling positioning device is not suitable for machining inclined deep inner holes of large hydraulic supports. Utility Model Content

[0004] In order to eliminate the step of welding the process steps in advance and realize the direct machining of the inclined deep inner hole of the hydraulic support using the radial drilling bit, the technical solution adopted by this utility model is: a hydraulic support radial drilling inclined hole tooling, which can be detachably installed on the top beam of the hydraulic support and located above the sleeve, including an inclined step block, a fixed frame plate and a pair of switchable magnetic seats.

[0005] The fixed frame plate is clamped between a pair of switchable magnetic seats, and the pair of switchable magnetic seats are magnetically attracted to the top beam of the hydraulic support. The fixed frame plate is provided with an inclined step block mounting cavity, and the inclined step block can be detachably installed in the inclined step block mounting cavity.

[0006] The inclined step block has a guide hole inside for guiding the rocker arm drill bit. The top surface of the inclined step block is horizontal, and the bottom surface of the inclined step block is inclined.

[0007] The angle between the top and bottom surfaces of the inclined step block is the same as the inclination angle of the hydraulic support top beam, so that the guide hole is in a vertical state when the inclined step block is attached to the hydraulic support top beam.

[0008] Based on the above, the fixed frame plate is a rectangular fixed frame plate, and a weight-reducing cavity is formed around the perimeter of the rectangular fixed frame plate.

[0009] Beneficial effects: By designing a weight-reducing cavity, the weight of the fixing frame plate can be reduced, facilitating assembly. Simultaneously, it ensures that the fixing frame plate is stably confined between the switchable magnetic bases, preventing it from shifting or wobbling.

[0010] Based on the above, the height of the pair of switch-type magnetic bases is greater than the thickness of the fixed frame plate.

[0011] Based on the above, the length value of the pair of switch-type magnetic bases is greater than or equal to the length value of the fixed frame plate.

[0012] Based on the above, the thickness value at the lowest point of the inclined step block is greater than or equal to the thickness value of the fixed frame plate.

[0013] The beneficial effect is that, by limiting the dimensions described above, it can be ensured that a pair of the aforementioned switch-type magnetic seats can provide sufficient gripping force.

[0014] Based on the above, the axis of the guide hole is set perpendicular to the top surface of the inclined step block.

[0015] Based on the above, the inclined step block mounting cavity is a rectangular inclined step block mounting cavity, and the rectangular inclined step block mounting cavity is located at the center of the fixed frame plate.

[0016] This utility model has substantial features and advancements compared to existing technologies. Specifically, it provides a hydraulic support rocker arm drilling fixture for beveled holes, designed as a combination of a pair of switchable magnetic seats, a beveled step block, and a fixed frame plate. The switchable magnetic seats replace the welded fixing process steps, avoiding welding and grinding work. Furthermore, the switchable magnetic seats allow for quick opening and disassembly of the fixed frame plate, improving installation and disassembly efficiency. Simultaneously, the beveled step block, matching the inclination angle of the hydraulic support top beam, is installed within the fixed frame plate, and its top surface is kept horizontal. This provides a vertical surface for beveled drilling, ensuring stability during the drilling process. Additionally, the guide holes on the beveled step block precisely guide the drill bit, preventing wobbling or deviation and ensuring the verticality and positional accuracy of the hole.

[0017] Furthermore, by creating several weight-reducing cavities in the fixed frame plate, the weight of the fixed frame plate is reduced, making it easier to disassemble and assemble.

[0018] Therefore, this radial drilling tool for hydraulic supports can eliminate the need for pre-welding process steps, enabling direct machining of the inclined deep inner hole of the hydraulic support using the radial drill bit. Attached Figure Description

Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is detachably mounted on the top beam 11 of the hydraulic support and located above the sleeve 12, including the inclined step block 2, the fixed frame plate 5 and a pair of switchable magnetic seats.

[0028] The fixed frame plate 5 is clamped between a pair of switch-type magnetic seats, which are magnetically attached to the top beam 11 of the hydraulic support. The fixed frame plate 5 is provided with an inclined step block mounting cavity 6. The inclined step block 2 is detachably installed within the inclined step block mounting cavity 6. Based on their distribution, the pair of switch-type magnetic seats can be divided into a first switch-type magnetic seat 1 and a second switch-type magnetic seat 4.

[0029] The inclined step block 2 has a guide hole 3 inside for guiding the rocker arm drill bit 10. The top surface of the inclined step block 2 is horizontal, forming a top horizontal surface 8. The bottom surface of the inclined step block 2 is inclined, forming a bottom inclined contact surface 9.

[0030] Specifically, the angle between the top and bottom surfaces of the inclined step block 2 is the same as the inclination angle of the hydraulic support top beam 11, so that when the inclined step block 2 is attached to the hydraulic support top beam 11, the guide hole 3 is in a vertical state.

[0031] Specifically, the axis of the guide hole 3 is perpendicular to the top surface of the inclined step block 2. The inclined step block mounting cavity 6 is a rectangular inclined step block mounting cavity, and the rectangular inclined step block mounting cavity 6 is located at the center of the fixed frame plate.

[0033] This embodiment provides a tooling for drilling inclined holes in a hydraulic support rocker arm. The main difference from Embodiment 1 is that in this embodiment, the fixing frame plate 5 is a rectangular fixing frame plate, and weight-reducing cavities 7 are formed around its perimeter. That is, by designing weight-reducing cavities, the weight of the fixing frame plate can be reduced, facilitating assembly. Simultaneously, it ensures that the fixing frame plate can be stably limited between the switch-type magnetic bases, preventing it from shifting or shaking.

[0034] Example 3

That is, by limiting the above dimensions, it can be ensured that the pair of switchable magnetic seats can provide sufficient gripping force.

[0036] Specifically, when using the hydraulic support rocker arm drill bevel hole tooling provided by this utility model for drilling, the specific steps are as follows:

[0037] First, select a matching inclined step block 2 according to the tilt angle of the hydraulic support top beam 11; then, corresponding to the position of the sleeve 12, attach the fixing frame plate 5 to the hydraulic support top beam 11, and use a pair of switch-type magnetic seats to magnetically adsorb the hydraulic support top beam to limit the fixing frame plate.

[0038] Finally, install the inclined step block into the inclined step block mounting cavity on the fixed frame plate, ensuring that the top surface of the inclined step block is horizontal.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
