Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and particularly to a drilling machine for producing anti-offset steel bar sleeves. Background Art

[0002] A steel bar sleeve, also known as a steel bar joint, is a connecting piece used to connect steel bars and having an internal thread corresponding to the thread of the threaded end. In some steel bar connection systems, it is necessary to drill holes in the steel bar sleeve to install specific connecting pieces, such as bolts, pins, etc. These connecting pieces can reliably connect the steel bar sleeve with other structural components to meet the mechanical performance requirements of the structure. In prefabricated buildings, grouting connection of steel bar sleeves is a common connection method. Drilling holes is to set grouting holes and slurry outlet holes so that high-strength grouting material can be injected into the sleeve during construction to form a tight connection between the steel bar and the sleeve. The grouting material enters the sleeve through the grouting hole, fills the gap between the steel bar and the sleeve, and overflows at the slurry outlet hole to ensure full grouting, thereby achieving reliable connection of the steel bars;

[0003] During the process of drilling the sleeve, when the positioning is incorrect, it will cause position deviation, resulting in rotation of the cylindrical sleeve during drilling, generating great resistance to the drill bit, causing the drill bit to break, and at the same time, the drilled sheets cannot be used. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] A drilling machine for producing anti-offset steel bar sleeves, comprising:

[0006] A frame body, on the top of which a slide rail is provided, and a slide seat is slidably installed on the top of the slide rail. A support plate is fixedly installed on the top of the slide seat, and an outer cover ring is fixedly installed on the top of the support plate. A first cylinder is fixedly installed on the top of the frame body, and the output end of the first cylinder is fixedly connected to both ends of the slide seat;

[0007] A drilling mechanism, which is fixedly installed on the top of the frame body;

[0008] A fixing mechanism, which is used to position the sleeve during the clamping and fixing process. A connecting cylinder is fixedly installed on the inner wall of the outer cover ring, and the fixing mechanism is installed inside the connecting cylinder;

[0009] One end of the connecting cylinder is fixedly installed with an end cover. The inner diameter of the end cover gradually increases at the end far from the connecting cylinder. An inner inclined plate is fixedly installed on the inner wall of the end cover. Through the inner inclined plate on the inner wall of the end cover, when the fixing structure performs clamping and fixing, it cooperates with the inner support plate to position both the inner and outer sides of the sleeve, improving the positioning accuracy. At the same time, the inner inclined plate cooperates with the inner support plate to make the inner inclined plate have a rigid contact with the sleeve, avoiding the position deviation of the sleeve, so that the drilling position of the sleeve and the traveling route of the drill bit deviate, resulting in the unusability of the sleeve for drilling. The inner inclined plates are evenly installed along the center position of the end cover. The other end of the connecting cylinder is fixedly installed with a hole plate. The hole plate is provided with sliding holes on the outside and is evenly installed along the center position of the connecting cylinder. A limiting block is fixedly installed at the center position of the inner wall of the connecting cylinder. By the cooperation of the limiting block and the hole plate, the movement path of the fixing mechanism in the connecting cylinder is restricted. At the same time, during the drilling process, the fixing mechanism provides a supporting force for the sleeve to ensure the normal progress of the sleeve drilling. The limiting blocks are evenly installed along the center position of the connecting cylinder.

[0010] Preferably, the fixing mechanism includes a sliding cylinder. One end of the sliding cylinder close to the hole plate on the outside is fixedly installed with an end plate. A sliding rod is fixedly installed on the outside of the end plate. The outside of the sliding rod is slidably adapted to the sliding hole of the hole plate. The outside of the sliding cylinder is slidably adapted to the opposite surface of the limiting block. One end of the sliding rod far from the end plate is provided with a disc, and a spring is fixedly installed between the disc and the hole plate. The sliding rod is located between the limiting blocks. One end of the inner wall of the sliding cylinder far from the end plate is fixedly installed with a chute block. A chute is opened on the side of the chute block far from the end plate. An elastic gasket ring is clamped at the chute of the chute block. A conical cylinder is slidably installed at the chute of the chute block. By the cooperation of the conical cylinder and the inner support plate, when contacting the sleeve, it supports the sleeve and completes the pre-positioning of the sleeve during the subsequent clamping and fixing. At the same time, during the clamping process, the conical cylinder compresses the elastic gasket ring, making the conical cylinder slide in the chute block. While providing a buffer range for the position positioning adjustment of the sleeve, the two ends of the sleeve can contact the rubber pads, increasing the contact area and the friction force with the two ends of the sleeve, avoiding the rotation of the sleeve during the drilling process and jamming the high-speed rotating drill bit, resulting in the breakage of the drill bit.

[0011] Preferably, the outer diameter of the tapered cylinder gradually decreases at the end away from the chute block, and an inner support plate is fixedly installed on the outer side of the tapered cylinder. A sliding sleeve is slidably installed at the end of the outer side of the sliding cylinder away from the end plate. A rubber pad is fixedly installed at the end of the sliding sleeve away from the end plate. An arc groove ring is fixedly installed on the outer side of the sliding cylinder. Arc notches are evenly formed at one end of the arc groove ring close to the sliding sleeve. Arc protrusions are evenly arranged at one end of the sliding sleeve close to the arc groove ring. Through the cooperation of the arc protrusions of the sliding sleeve and the arc notches of the arc groove ring, during the drilling process, when the sleeve has a tendency to rotate, the acting force is transmitted to the sliding sleeve through the rubber ring, causing the sliding sleeve to have a tendency to rotate accordingly. At this time, through the contact between the arc notches and the arc protrusions, while having a tendency to rotate, a tendency to squeeze the sliding sleeve and the rubber ring towards the sleeve direction is generated, increasing the contact pressure and the friction force, restricting the rotation of the sleeve, ensuring the normal progress of the drilling work, and the arc protrusions and the arc notches correspond one by one.

[0012] Preferably, the drilling mechanism includes a chute plate. The bottom of the chute plate is fixedly connected to the top of the frame body. Chutes are symmetrically formed on the outer side of the chute plate. A top plate is slidably installed at the chute of the chute plate. A second cylinder is fixedly installed on the outer side of the chute plate. The output end of the second cylinder is fixedly connected to the bottom of the top plate. A motor is fixedly installed on the top of the top plate. The output end of the motor penetrates through the top plate and extends to its bottom. The output end of the motor is fixedly installed with a tool holder through a coupling. A drill bit is fixedly installed at the bottom of the tool holder. Side plates are fixedly installed at the bottom of the top plate. The side plates are symmetrically installed along the central axis position of the top plate and are located on both sides of the drill bit. Through grooves are symmetrically formed on the outer sides of the side plates. Sliding plates are slidably installed at the through grooves of the side plates. Oblique groove plates are fixedly installed at the bottom ends of the sliding plates. Through the cooperation of the oblique groove plates and the oblique baffles, using the inclined surfaces of the oblique groove plates, when contacting the sleeve, the sleeve is restricted. At the same time, workers can further judge the accuracy of positioning according to the contact between the sleeve and the inclined surfaces of the oblique groove plates. At the same time, the oblique groove plates and the oblique baffles form a barrier around the drilling position, blocking the splashing of drilling debris and avoiding damage caused by the splashing of high-temperature debris generated by drilling. An oblique groove is formed at the central position of the bottom of the oblique groove plate, and oblique baffles are fixedly installed at both ends of the opposite surfaces of the oblique groove plate.

[0013] The present invention provides a drilling machine for producing anti-offset steel bar sleeves, which has the following beneficial effects:

[0014] First, for the drilling machine for producing anti-offset steel bar sleeves, through the inner inclined plate on the inner wall of the end cover, when the fixing structure performs clamping and fixing, it cooperates with the inner support plate to perform positioning processing on both the inner and outer sides of the sleeve, improving the accuracy of positioning. At the same time, the inner inclined plate and the inner support plate cooperate, enabling the inner inclined plate to make rigid contact with the sleeve, avoiding the offset of the sleeve position, and preventing the deviation between the drilling position of the sleeve and the traveling route of the drill bit, resulting in the unusability of the drilled sleeve.

[0015] 2. The drilling machine for producing anti-offset steel bar sleeves restricts the movement path of the fixing mechanism in the connecting cylinder through the cooperation of the limit block and the hole plate. At the same time, during the drilling process, the fixing mechanism provides a supporting force for the sleeve to ensure the normal progress of sleeve drilling.

[0016] 3. The drilling machine for producing anti-offset steel bar sleeves supports the sleeve when contacting the sleeve through the cooperation of the conical cylinder and the inner support plate, and completes the pre-positioning of the sleeve during subsequent clamping and fixing. At the same time, during the clamping process, the conical cylinder compresses the elastic gasket ring, causing the conical cylinder to slide in the chute block. While providing a buffering range for the positioning adjustment of the sleeve position, the two ends of the sleeve can contact the rubber pads, increasing the contact area and the friction force with the two ends of the sleeve, avoiding the sleeve from rotating during the drilling process and jamming the high-speed rotating drill bit, resulting in the breakage of the drill bit.

[0017] 4. The drilling machine for producing anti-offset steel bar sleeves, through the cooperation of the arc convex block of the sliding sleeve and the arc notch groove of the arc groove ring, during the drilling process, when the sleeve has a tendency to rotate, the acting force is transmitted to the sliding sleeve through the rubber ring, causing the sliding sleeve to have a tendency to rotate accordingly. At this time, through the contact between the arc notch groove and the arc convex block, while having a tendency to rotate, a tendency to squeeze the sliding sleeve and the rubber ring towards the sleeve direction is generated, increasing the contact pressure and the friction force, restricting the rotation of the sleeve, and ensuring the normal progress of the drilling work.

[0018] 5. The drilling machine for producing anti-offset steel bar sleeves restricts the sleeve through the cooperation of the inclined groove plate and the inclined baffle, using the inclined surface of the inclined groove plate when contacting the sleeve. At the same time, workers can further judge the accuracy of positioning according to the contact between the sleeve and the inclined surface of the inclined groove plate. At the same time, the inclined groove plate and the inclined baffle form a barrier around the drilling position to block the splashing of drilling debris and avoid the harm caused by the splashing of high-temperature debris generated by drilling.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] A drilling mechanism 3, which is fixedly installed on the top of the frame body 1;

[0034] The drilling mechanism 3 includes a chute plate 301. The bottom of the chute plate 301 is fixedly connected to the top of the frame body 1, and chutes are symmetrically formed on the outer side of the chute plate 301.

A second cylinder 302 is fixedly installed on the outer side of the chute plate 301, and the output end of the second cylinder 302 is fixedly connected to the bottom of the top plate 303. After starting the motor 304, the output end of the motor 304 drives the drill bit 307 to rotate at high speed through the tool holder 306. At the same time, during the rotation process, the second cylinder 302 drives the top plate 303 to move downward, so that the drill bit 307 approaches the drilling position at the top of the sleeve, and during the gradual downward movement, the sleeve is drilled. A motor 304 is fixedly installed on the top of the top plate 303. The output end of the motor 304 penetrates through the top plate 303 and extends to its bottom. The output end of the motor 304 is fixedly installed with a tool holder 306 through a coupling, and the bottom of the tool holder 306 is fixedly installed with a drill bit 307;

[0035] The fixing mechanism 2 is used to position the sleeve during the clamping and fixing process. A connecting cylinder 8 is fixedly installed on the inner wall of the outer cover ring 4, and the fixing mechanism 2 is installed inside the connecting cylinder 8;

[0036] The fixing mechanism 2 includes a sliding cylinder 201. A end plate 202 is fixedly installed at one end of the sliding cylinder 201 close to the hole plate 12. A sliding rod 203 is fixedly installed on the outer side of the end plate 202, and the outer side of the sliding rod 203 is slidably adapted to the sliding hole of the hole plate 12. The outer side of the sliding cylinder 201 is slidably adapted to the opposite surface of the limiting block 11. A disc is arranged at one end of the sliding rod 203 away from the end plate 202. During the fixing process by the fixing mechanism 2, the conical surface of the conical cylinder 208 contacts the edge positions at both ends of the inner wall of the inner support plate 209 and the sleeve. During the gradual clamping process, the position of the sleeve is gradually positioned through the cooperation of the conical surface of the conical cylinder 208 and the inner support plate 209. A spring 204 is fixedly installed between the disc and the hole plate 12. The sliding rod 203 is located between the limiting blocks 11. A chute block 210 is fixedly installed at one end of the inner wall of the sliding cylinder 201 away from the end plate 202. A chute is formed on one side of the chute block 210 away from the end plate 202. An elastic gasket ring 211 is clamped at the chute of the chute block 210. A conical cylinder 208 is slidably installed at the chute of the chute block 210;

[0037] One end of the connecting cylinder 8 is fixedly installed with an end cover 9. The inner diameter of the end cover 9 gradually increases at the end far from the connecting cylinder 8. The inner wall of the end cover 9 is fixedly installed with an inner inclined plate 10. The inner inclined plates 10 are evenly installed along the center position of the end cover 9. The other end of the connecting cylinder 8 is fixedly installed with an orifice plate 12. The orifice plate 12 is provided with sliding holes on the outside and is evenly installed along the center position of the connecting cylinder 8. During the clamping process, the first cylinder 5 drives the sliding seats 6 on both sides to approach each other, driving the fixing mechanism 2 and the connecting cylinder 8 close to both ends of the sleeve. The fixing mechanism 2 first contacts the sleeve and slides in the connecting cylinder 8 under the clamping pressure, so that the inner inclined plate 10 on the inner wall of the end cover 9 contacts the outer edge positions at both ends of the sleeve, and cooperates with the fixing mechanism 2 for rigid clamping. At the same time, the inner inclined plate 10 uses the conical surface of the end cover 9 to cooperate with the fixing mechanism 2 for positioning while clamping. A limiting block 11 is fixedly installed at the center position of the inner wall of the connecting cylinder 8. The limiting blocks 11 are evenly installed along the center position of the connecting cylinder 8.

[0038] The second embodiment, on the basis of the first embodiment, please refer to Figures 6 to 7 As shown, the outer diameter of the tapered cylinder 208 gradually decreases at the end far from the chute block 210. The outer side of the tapered cylinder 208 is fixedly installed with an inner support plate 209. A sliding sleeve 206 is slidably installed at the end of the outer side of the sliding cylinder 201 far from the end plate 202. A rubber pad 207 is fixedly installed at the end of the sliding sleeve 206 far from the end plate 202. An arc groove ring 205 is fixedly installed on the outer side of the sliding cylinder 201. During the movement process, it cooperates with the inner inclined plate 10 on the inner wall of the end cover 9. After the inner support plate 209 positions the sleeve, under the clamping pressure, the tapered cylinder 208 compresses the elastic gasket ring 211 to deform, and the tapered cylinder 208 slides inward under the restriction of the chute block 210, so that both ends of the sleeve contact the rubber pad 207. The clamping pressure of the first cylinder transmits the pressure to the spring 204, causing it to be compressed and deformed under the sliding of the sliding rod 203. At the same time, the sliding cylinder 201 slides in the connecting cylinder 8, and at the same time increases the contact pressure between the rubber pad 207 and both ends of the sleeve until the outer edge positions at both ends of the sleeve contact the inner inclined plate 10, so that the inner inclined plate 10 and the inner support plate 209 cooperate to complete the fixed positioning and clamping of the sleeve. The arc groove ring 205 is evenly provided with arc notches at the end close to the sliding sleeve 206. The sliding sleeve 206 is evenly provided with arc convex blocks at the end close to the arc groove ring 205, and the arc convex blocks correspond to the arc notches one by one.

[0039] The third embodiment, on the basis of the first and second embodiments, please refer to Figures 8 to 9As shown, a side plate 305 is fixedly installed at the bottom of the top plate 303. The side plates 305 are symmetrically installed along the central axis position of the top plate 303, and the side plates 305 are located on both sides of the drill bit 307. Through grooves are symmetrically formed on the outer sides of the side plates 305, and a sliding plate 310 is slidably installed at the through groove of the side plate 305. An inclined groove plate 309 is fixedly installed at the bottom end of each sliding plate 310. Before the drill bit 307 touches the sleeve, through the inclined groove at the central position of the bottom of the inclined groove plate 309, it touches the top of the sleeve, and the sleeve is restricted and positioned through the inclined groove. Subsequently, during the process of the drill bit 307 continuously moving downward for drilling, the fixed sleeve restricts the downward movement of the inclined groove plate 309, causing the sliding plate 310 to slide at the through groove of the side plate 305. At the same time, during the drilling process of the drill bit 307, through the cooperation of the inclined groove plate 309 and the inclined baffle 308, a barrier is formed around the drilling position to block the high-temperature debris generated by drilling. An inclined groove is formed at the central position of the bottom of the inclined groove plate 309, and inclined baffles 308 are fixedly installed at both ends of the opposite surfaces of the inclined groove plate 309.

[0040] During use, the worker places the reinforcing bar sleeve to be drilled between the fixing mechanisms 2. At the same time, the worker can start the first cylinder 5 according to the length of the sleeve, control the distance between the fixing mechanisms 2, so that the fixing mechanisms 2 pre-fix the sleeve. Subsequently, the worker releases the sleeve, and then controls the first cylinder 5 again, so that the fixing mechanisms 2 clamp and fix the material. At the same time, during the fixing process, the position of the sleeve is positioned. Subsequently, the drilling mechanism 3 drives the tool to rotate and moves downward during the rotation process to drill the top of the sleeve.

[0041] During the clamping process, the first cylinder 5 drives the sliding seats 6 on both sides to approach each other, driving the fixing mechanisms 2 and the connecting cylinder 8 to approach both ends of the sleeve, and making the fixing mechanisms 2 first contact the sleeve. Under the clamping pressure, the fixing mechanisms 2 slide in the connecting cylinder 8, so that the inner inclined plates 10 on the inner wall of the end cover 9 contact the outer edge positions at both ends of the sleeve, and cooperate with the fixing mechanisms 2 for rigid clamping. At the same time, the inner inclined plates 10 utilize the conical surface of the end cover 9 to cooperate with the fixing mechanisms 2 to perform positioning while clamping.

[0042] During the fixation process by the fixing mechanism 2, the conical surface of the conical cylinder 208 is installed in contact with the edge positions at both ends of the inner support plate 209 and the inner wall of the sleeve. During the gradual clamping process, the conical surface of the conical cylinder 208 cooperates with the inner support plate 209 to gradually position the sleeve. At the same time, during the movement process, it cooperates with the inner inclined plate 10 on the inner wall of the end cover 9. After the inner support plate 209 positions the sleeve, under the clamping pressure, the elastic gasket ring 211 is compressed and deformed by the conical cylinder 208, causing the conical cylinder 208 to slide inward under the restriction of the chute block 210, making both ends of the sleeve contact the rubber gasket 207. And the clamping pressure of the first cylinder transmits the pressure to the spring 204, causing it to be compressed and deformed under the sliding of the sliding rod 203. At the same time, the sliding cylinder 201 slides in the connecting cylinder 8, and at the same time increases the contact pressure between the rubber gasket 207 and both ends of the sleeve until the edge positions on the outer sides of both ends of the sleeve contact the inner inclined plate 10, making the inner inclined plate 10 cooperate with the inner support plate 209 to complete the fixed positioning and clamping fixation of the sleeve.

[0043] In the drilling mechanism 3, after starting the motor 304, the output end of the motor 304 drives the drill bit 307 to rotate at high speed through the tool holder 306. At the same time, during the rotation process, the second cylinder 302 drives the top plate 303 to move downward, making the drill bit 307 approach the drilling position at the top of the sleeve. During the gradual downward movement process, the sleeve is drilled. Before the drill bit 307 contacts the sleeve, through the inclined groove at the center position of the bottom of the inclined groove plate 309, it contacts the top of the sleeve, and the sleeve is restricted and positioned through the inclined groove. Subsequently, during the continuous downward movement of the drill bit 307 for drilling, the fixed sleeve restricts the downward movement of the inclined groove plate 309, causing the sliding plate 310 to slide at the through groove of the side plate 305. At the same time, during the drilling process of the drill bit 307, the inclined groove plate 309 cooperates with the inclined baffle 308 to form a barrier around the drilling position to block the high-temperature debris generated by drilling.
