Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drilling equipment, in particular to a steel sleeve production drilling machine capable of preventing deviation. BACKGROUND

[0002] Steel sleeve, also known as steel joint, is a connecting piece used to connect steel bars and has internal threads corresponding to the threads of the wire head. In some steel connecting systems, specific connecting pieces such as bolts and pins need to be installed by drilling holes on the steel sleeve. These connecting pieces can reliably connect the steel sleeve with other structural components to meet the mechanical performance requirements of the structure. In prefabricated buildings, steel sleeve grouting connection is a common connection method. Drilling is done to set grouting holes and discharge holes to allow high-strength grouting material to be injected into the sleeve during construction, forming a tight connection between the steel bar and the sleeve. Grouting material enters the sleeve through the grouting hole, fills the gap between the steel bar and the sleeve, and overflows at the discharge hole to ensure full grouting, thereby achieving reliable connection of the steel bar.

[0003] During the drilling of the sleeve, if the positioning is incorrect, it will cause deviation, causing the cylindrical sleeve to rotate during drilling, generating a great resistance to the drill bit, causing the drill bit to break, and the drilled piece cannot be used. SUMMARY

[0004] To achieve the above purpose, the present application is realized by the following technical scheme:

[0005] A steel sleeve production drilling machine capable of preventing deviation, comprising:

[0006] a frame body, a slide rail is arranged on the top of the frame body, 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, an outer cover ring is fixedly installed on the top of the support plate, a first air cylinder is fixedly installed on the top of the frame body, and the output end of the first air cylinder is fixedly connected with both ends of the slide seat;

[0008] a fixing mechanism, which is used for positioning the sleeve during clamping and fixing, an inner wall of the outer cover ring is fixedly installed with a connecting barrel, and the fixing mechanism is installed in the inner part of the connecting barrel;

[0009] One end of the connecting barrel is fixedly installed with an end cover, the inner diameter of the end cover gradually increases away from the one end of the connecting barrel, and the inner wall of the end cover is fixedly installed with an inner inclined plate. Through the inner inclined plate of the inner wall of the end cover, when the fixed structure is clamped and fixed, the inner inclined plate cooperates with the inner support plate to position the inner and outer sides of the sleeve, improve the accuracy of positioning, and the cooperation of the inner inclined plate and the inner support plate enables the inner inclined plate to rigidly contact the sleeve, avoids the position deviation of the sleeve, avoids the deviation between the drilling position of the sleeve and the travel route of the drill bit, and causes the sleeve for drilling to be unable to be used. The inner inclined plate is uniformly installed along the center position of the end cover, and the other end of the connecting barrel is fixedly installed with a hole plate. The hole plate is provided with a sliding hole along the outer side and is uniformly installed along the center position of the connecting barrel. A limiting block is fixedly installed at the center position of the inner wall of the connecting barrel. Through the cooperation of the limiting block and the hole plate, the movement path of the fixed mechanism in the connecting barrel is limited, and at the same time, in the process of drilling, the fixed mechanism provides support for the sleeve to ensure the normal drilling of the sleeve. The limiting block is uniformly installed along the center position of the connecting barrel.

[0010] Preferably, the fixed mechanism comprises a sliding cylinder, one end of the sliding cylinder is fixedly installed with an end disc close to the hole plate, the outer side of the end disc is fixedly installed with a sliding rod, the outer side of the sliding rod is slidably matched with the sliding hole of the hole plate, the outer side of the sliding cylinder is slidably matched with the opposite surface of the limiting block, one end of the sliding rod away from the end disc 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 away from the end disc is fixedly installed with a sliding groove block, one side of the sliding groove block away from the end disc is provided with a sliding groove, and the sliding groove of the sliding groove block is clamped with an elastic washer. A conical cylinder is slidably installed in the sliding groove of the sliding groove block. Through the cooperation of the conical cylinder and the inner support plate, the sleeve is supported when contacting the sleeve, and the pre-positioning of the sleeve is completed in the subsequent clamping and fixing. At the same time, in the clamping process, the conical cylinder compresses the elastic washer, so that the conical cylinder slides in the sliding groove block, provides a buffer range for the position positioning of the sleeve, and enables the two ends of the sleeve to contact the rubber pad, increases the contact area, increases the friction force with the two ends of the sleeve, avoids the rotation of the sleeve in the drilling process, and avoids the sleeve from being stuck in the high-speed rotating drill bit, which causes the drill bit to break.

[0011] Preferably, the outer diameter of the conical cylinder gradually decreases away from one end of the chute block, and the outer side of the conical cylinder is fixedly provided with an inner support plate; the outer side of the sliding cylinder is slidingly provided with a sliding sleeve away from one end of the end disc; the outer side of the sliding sleeve is fixedly provided with a rubber pad away from one end of the end disc; the outer side of the sliding cylinder is fixedly provided with an arc groove ring; the arc groove ring is uniformly provided with arc notch grooves at one end close to the sliding sleeve; and the sliding sleeve is uniformly provided with arc protrusions at one end close to the arc groove ring. Through cooperation of the arc protrusions of the sliding sleeve and the arc notch grooves of the arc groove ring, when the sleeve has a tendency to rotate during drilling, the force is transmitted to the sliding sleeve through the rubber ring, so that the sliding sleeve has a tendency to rotate; at this time, through contact of the arc notch grooves and the arc protrusions, the sliding sleeve and the rubber ring are pressed towards the sleeve, the contact pressure is increased, the friction force is increased, the sleeve rotation is limited, the drilling work is ensured to be normally carried out, and the arc protrusions and the arc notch grooves correspond to each other.

[0012] Preferably, the drilling mechanism comprises a chute plate, the bottom of the chute plate is fixedly connected with the top of the frame body, and the outer side of the chute plate is symmetrically provided with a sliding groove; a top plate is slidingly installed at the sliding groove of the chute plate; a second air cylinder is fixedly installed on the outer side of the chute plate; the output end of the second air cylinder is fixedly connected with the bottom of the top plate; a motor is fixedly installed on the top of the top plate; the output end of the motor extends to the bottom of the top plate through the top plate; a tool shank is fixedly installed on the output end of the motor through a shaft coupling; a drill bit is fixedly installed on the bottom of the tool shank; a side plate is fixedly installed on the bottom of the top plate; the side plate is symmetrically installed along the axial center position of the top plate; the side plate is located on both sides of the drill bit; the outer side of the side plate is symmetrically provided with a through groove; a sliding plate is slidingly installed at the through groove of the side plate; and the bottom end of the sliding plate is fixedly provided with an inclined groove plate.

[0013] The application provides a drilling machine for anti-deviation steel sleeve production.

[0014] The anti-deviation steel sleeve production drilling machine is provided with an inner inclined plate on the inner wall of the end cover. When the fixed structure is clamped and fixed, the inner inclined plate cooperates with the inner support plate to position the inner and outer sides of the sleeve, improve the positioning accuracy, and make the inner inclined plate rigidly contact the sleeve to avoid the position deviation of the sleeve, so that the drilling position of the sleeve deviates from the advancing route of the drill bit, and the drilled sleeve cannot be used.

[0015] II. The anti-deviation steel sleeve production drilling machine limits the movement path of the fixing mechanism in the connecting cylinder through the cooperation of the limiting block and the hole plate, and provides support for the sleeve during drilling to ensure the normal drilling of the sleeve.

[0016] III. The anti-deviation steel sleeve production drilling machine 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. During clamping, the conical cylinder compresses the elastic washer, allowing the conical cylinder to slide in the sliding groove block, providing a buffer range for the positioning and adjustment of the sleeve position, allowing the two ends of the sleeve to contact the rubber pad, increasing the contact area and the friction with the two ends of the sleeve, and avoiding the sleeve from rotating during drilling, getting stuck with the high-speed rotating drill bit, and causing the drill bit to break.

[0017] IV. The anti-deviation steel sleeve production drilling machine cooperates the arc convex block of the sliding sleeve with the arc missing groove of the arc groove ring. During drilling, when the sleeve tends to rotate, the force is transmitted to the sliding sleeve through the rubber ring, causing the sliding sleeve to tend to rotate. At this time, the arc missing groove and the arc convex block are in contact, causing the sliding sleeve and the rubber ring to be squeezed in the direction of the sleeve, increasing the contact pressure and the friction, limiting the rotation of the sleeve, and ensuring the normal drilling work.

[0018] V. The anti-deviation steel sleeve production drilling machine cooperates the inclined groove plate with the inclined baffle plate, uses the inclined surface of the inclined groove plate to limit the sleeve when contacting the sleeve, and further judges 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 plate form a barrier around the drilling position, blocking the splashing of drilling debris, and avoiding the splashing of high-temperature debris generated during drilling from causing harm.

[0040] In use, the worker puts the required reinforcing steel sleeve for drilling between the fixed mechanisms 2, and at the same time the worker can control the distance between the fixed mechanisms 2 by starting the first cylinder 5 according to the length of the sleeve, so that the fixed mechanisms 2 pre-fix the sleeve, and then the worker loosens the sleeve, and then controls the first cylinder 5 again to make the fixed mechanisms 2 clamp and fix the material, and at the same time the position of the sleeve is positioned in the process of fixing, and then the drill bit is driven to rotate by the drilling mechanism 3, and moves downward in the process of rotation to drill the top of the sleeve.

[0041] In the clamping process, the first cylinder 5 drives the two sliding seats 6 on the sides to approach each other, drives the fixed mechanisms 2 to approach the two ends of the connecting cylinder 8, and makes the fixed mechanisms 2 first contact the sleeve, and under the clamping pressure, the fixed 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 of the two ends of the sleeve, and cooperate with the fixed mechanisms 2 to rigidly clamp, and at the same time the inner inclined plates 10 cooperate with the fixed mechanisms 2 through the conical surface of the end cover 9 to position while clamping.

[0042] In the process of fixing by the fixing mechanism 2, the taper surface of the taper cylinder 208 is installed in contact with the edge position of the inner support plate 209 and the inner wall of the sleeve, and gradually clamps the position of the sleeve in the process of gradually clamping, and the taper surface of the taper cylinder 208 cooperates with the inner support plate 209 to gradually position the position of the sleeve, and in the process of moving, cooperates with the inner inclined plate 10 of the inner wall of the end cover 9, so that the inner support plate 209 realizes the positioning of the sleeve. After the positioning of the sleeve, under the clamping pressure, the elastic gasket ring 211 is compressed by the taper cylinder 208 to deform, so that the taper cylinder 208 slides inward under the limitation of the sliding groove block 210, so that the two ends of the sleeve contact the rubber pad 207, and the clamping pressure of the first cylinder is transmitted to the spring 204, so that it is 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 the contact pressure of the rubber pad 207 and the two ends of the sleeve is increased, until the edge position of the two ends of the sleeve contacts the inner inclined plate 10, so that the inner inclined plate 10 cooperates with the inner support plate 209, and the fixing and clamping of the sleeve are completed.

[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, and in the process of rotating, the top plate 303 is driven downward by the second cylinder 302, so that the drill bit 307 approaches the drilling position on the top of the sleeve, and in the process of gradually moving downward, the sleeve is drilled. Before the drill bit 307 contacts the sleeve, the inclined slot at the bottom center position of the inclined slot plate 309 contacts the top of the sleeve, and the inclined slot plate 309 is limited and positioned by the inclined slot, and then in the process of continuously moving downward of the drill bit 307 for drilling, the fixed sleeve limits the downward movement of the inclined slot plate 309, so that the sliding plate 310 slides at the through slot of the side plate 305, and in the process of drilling of the drill bit 307, the inclined slot plate 309 cooperates with the inclined baffle plate 308 to form a barrier around the drilling position, blocking the high-temperature debris generated by drilling.
