Description

Technical Field

[0001] The invention relates to the technical field of drilling processing, and in particular to a steel structure component drilling device. Background Art

[0002] The connecting sleeve is a steel structure connecting piece in the shape of a stepped shaft (such as Figure 8 As shown), it realizes precise positioning and connection through pipes of different diameters; when used for the installation of scaffolding, since different structural parts of the scaffolding need to bear different loads, for example, the bottom of the scaffolding needs to bear more weight, so a thicker column is required, while a thinner column can be used at the top. At this time, the columns of different diameters can be connected by connecting sleeves, thereby ensuring the structural strength of the scaffolding while reducing the weight as much as possible and improving the utilization rate of materials; in addition, after the large-diameter section of the connecting sleeve is inserted into the column that bears the main load, the connecting sleeve and the column are fixed by bolts through the mounting holes evenly opened on the circumferential wall of the large-diameter section of the connecting sleeve to ensure the stability of the connection, while the small-diameter section can be directly inserted into the small-diameter column with less force to simplify the installation process of the scaffolding.

[0003] At present, when drilling a connecting sleeve, a small diameter section is usually clamped and fixed by a three-jaw chuck, and then drilled by a drilling device. After each mounting hole is drilled, the three-jaw chuck drives the fixed connecting sleeve to rotate a certain angle to realize the sequential processing of the mounting holes on the connecting sleeve.

[0004] However, the current connecting sleeve drilling process has the following problems: the connecting sleeve is only fixed and the angle is adjusted by a three-jaw chuck, which is prone to uneven clamping force, causing the connecting sleeve to shift during the processing, resulting in uneven distribution of the mounting holes on the connecting sleeve, causing uneven stress during installation and use, which in turn leads to premature fatigue or deformation, affecting the structural stability and service life of the entire component; secondly, the existing processing method can only process one connecting sleeve at a time, which makes the production cycle longer and requires frequent disassembly and adjustment of the position of the connecting sleeve, thus affecting the overall production efficiency. Summary of the invention

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] like Figure 1As shown, a steel structure component drilling equipment includes an equipment frame 10; a base plate 11 is installed on the equipment frame 10, and a fixing mechanism 2 for fixing two connecting sleeves and a drilling mechanism 3 for drilling the connecting sleeves are provided on the base plate 11, and the drilling mechanism 3 is located above the fixing mechanism 2.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixing mechanism 2 includes a fixing seat 20, the fixing seat 20 is installed on the upper end of the base plate 11, a fixing column 21 is rotatably installed on the fixing seat 20, and circular grooves 22 are coaxially provided at both ends of the fixing column 21. A pushing portion 25 for pushing the connecting sleeve is provided on the base plate 11, and a clamping portion 24 for clamping and fixing the connecting sleeve in cooperation with the pushing portion 25 is provided in the circular groove 22. A positioning portion 23 for positioning and supporting the connecting sleeve and a driving portion 26 for driving the fixing column 21 to rotate are provided on the fixing seat 20.

[0035] like Figure 1 and Figure 2 As shown, the drilling mechanism 3 includes a shaft rod 30, and the shaft rod 30 is symmetrically installed on the fixed seat 20. The lower end of the shaft rod 30 slides through the fixed seat 20 and the base plate 11 in sequence, and a fixing frame 31 is fixedly installed on the upper ends of the front-back symmetrical shaft rod 30. A drilling portion 32 is provided on the fixing frame 31, and a push-pull portion 34 for pushing and pulling the drilling portion 32 to move up and down is provided on the base plate 11. A locking portion 33 is provided on the fixing frame 31 to cooperate with the pushing portion 25 and the positioning portion 23 to restrain each other and limit the movement of the connecting sleeve.

[0036] During the specific operation, the smaller diameter sections of the two connecting sleeves are manually inserted into the corresponding circular grooves 22 to pre-fix the connecting sleeves, and then the pushing plate 251 pushes the connecting sleeves to move toward the fixing seat 20, so that the connecting sleeves collide with the end faces of the fixing columns 21, and at the same time drive the clamping portion 24 to squeeze the circumferential outer wall of the connecting sleeves to fix the connecting sleeves, and then the push-pull portion 34 drives the drilling portion 32 to move downward, and the drilling portion 32 moves downward to perform drilling processing on the corresponding connecting sleeves, and when the drilling portion 32 moves downward, the locking portion 33 will limit the drilling mechanism 3, the pushing portion 25 and the fixing column 21, so that the three are mutually restricted to improve the stability of the drilling processing of the connecting sleeves.

[0037] After an installation hole is machined in the connecting sleeve, the driving part 26 drives the fixing column 21 and the fixed connecting sleeve to rotate, so that the machined installation hole moves to the position of the positioning part 23. The positioning part 23 then cooperates with the installation hole. Then, the driving part 26 drives the fixing column 21, the positioning part 23 and the connecting sleeve to rotate by a certain angle to machine the next installation hole. After moving into place, the positioning part 23 further restricts the movement of the fixing column 21 to further improve the quality and precision of the machining of the connecting sleeve.

[0038] As Figure 1 and Figure 2 shown, the pushing part 25 includes a bidirectional screw 250. The upper end of the bottom plate 11 is rotatably installed with a bidirectional screw 250 that movably penetrates the fixed seat 20 through a bearing plate. Two pushing plates 251 that are symmetric about the fixed seat 20 left and right and are threadedly connected to the bidirectional screw 250 are slidably installed on the upper end of the bottom plate 11. A turntable 252 coaxial with the fixing column 21 is rotatably installed on the pushing plate 251. The right end of the right bearing plate is fixedly installed with a second motor 253, and the output shaft of the second motor 253 is fixedly connected to the bidirectional screw 250.

[0039] As Figure 1 , Figure 4 , Figure 5 and Figure 6 shown, the clamping part 24 includes a limiting groove 240. Limiting grooves 240 that are symmetric front and back and communicate with the corresponding circular grooves 22 are opened on both the left and right sides of the fixing column 21. A support plate 241 in a U-shaped structure is slidably installed together in the symmetric front and back limiting grooves 240. A third compression spring 242 is installed between the opposite surfaces of the left and right support plates 241 and the inner wall of the corresponding circular groove 22. Clamping blocks 243 are slidably installed at the ends of the two horizontal sections of the support plate 241 away from the corresponding third compression spring 242, and the clamping blocks 243 are slidably installed in the corresponding limiting grooves 240. Guide posts 244 are installed at both the upper and lower ends of the clamping blocks 243, and inclined grooves 245 corresponding to the guide posts 244 are opened in the limiting grooves 240.

[0040] During specific operation, the second motor 253 operates to drive the bidirectional screw 250 to rotate. The bidirectional screw 250 drives the two pushing plates 251 to approach each other to push the corresponding connecting sleeve through the corresponding turntable 252. The connecting sleeve will then push the corresponding support plate 241 towards the corresponding third compression spring 242, and at the same time compress the third compression spring 242. The support plate 241 drives the corresponding two clamping blocks 243 to move. Under the cooperation of the corresponding guide posts 244 and the corresponding inclined grooves 245, the clamping blocks 243 will approach the connecting sleeve during the moving process to squeeze and fix the connecting sleeve. And at this time, the large-diameter section of the connecting sleeve abuts against the end face of the fixing column 21. Then, the drilling mechanism 3 drills the connecting sleeve.

[0041] After the required mounting holes on the connecting sleeve are processed, the No. 2 motor 253 drives the bidirectional screw 250 to move in opposite directions, so that the pushing plate 251 moves away from the connecting sleeve. The support plate 241 is reset under the action of the No. 3 compression spring 242 and pushes the connecting sleeve to move a certain distance outside the circular groove 22. The movement of the support plate 241 will drive the clamping block 243 to move to release the squeezing and fixation of the connecting sleeve. At this time, the connecting sleeve can be replaced.

[0042] like Figure 2 and Figure 3 As shown, the driving part 26 includes a driven rotating plate 260, and the fixed column 21 is fixedly mounted with a driven rotating plate 260 which is symmetrical with respect to the fixed seat 20, wherein a driven gear is fixedly sleeved on the outer side of one of the driven rotating plates, and a No. 3 motor 261 is fixedly mounted on the upper end of the fixed seat 20, and a driving gear 262 meshing with the driven gear is fixedly mounted on the output shaft of the No. 3 motor 261.

[0043] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the positioning portion 23 includes an arc-shaped plate 230, and the left and right ends of the fixed seat 20 are fixedly installed with an arc-shaped plate 230 coaxial with the fixed column 21, and the end of the arc-shaped plate 230 away from the fixed seat 20 is fixedly installed with an arc-shaped slide rail 231 coaxial with the fixed column 21, and the moving section of the arc-shaped slide rail 231 is fixedly installed with an electric push rod 232, and the telescopic end of the electric push rod 232 is installed with a support plate 233 with an inverted L-shaped structure, and the front end of the longitudinal section of the support plate 233 is fixedly installed There is a rectangular plate 234, the front end of the rectangular plate 234 is installed with an extrusion plate 236 through a No. 1 compression spring 235, the rear end of the extrusion plate 236 is evenly fixed with a sliding rod that slides through the corresponding rectangular plate 234, and the extrusion plate 236 is evenly and slidably installed with positioning blocks 237 of a right-angled trapezoidal structure in a circular distribution. The rectangular plate 234 is provided with an actuator 5 for extruding and driving the positioning block 237 to move, and the support plate 233 is provided with a limiter 4 for limiting the movement of the electric push rod 232.

[0044] like Figure 5 , Figure 6 and Figure 7 As shown, the actuator 5 includes a slide groove, and a slide groove corresponding to the positioning block 237 and penetrating the extrusion plate 236 is opened on the extrusion plate 236. A slider 50 is slidably installed in the slide groove, and a No. 2 compression spring 51 is installed between the end of the slider 50 away from the middle of the extrusion plate 236 and the inner wall of the slide groove. The end of the slider 50 away from the corresponding No. 2 compression spring 51 is fixedly connected to the corresponding positioning block 237, and a pushing rod 52 is fixedly installed at the front end of the rectangular plate 234, which contacts the corresponding positioning block 237 and slides through the corresponding extrusion plate 236, and the front end of the pushing rod 52 is a truncated cone structure.

[0045] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the limiting member 4 includes a circular ring 40, and the circular ring 40 is coaxially fixedly installed on the end of the driven rotating plate 260 away from the fixed seat 20, and the side walls of the arc plate 230 and the circular ring 40 are both uniformly provided with limiting holes 41 along the circumference of the fixed column 21, and the front end of the transverse section of the support plate 233 is fixedly installed with a limiting rod 42, and the limiting rod 42 slides through the limiting holes 41 on the arc plate 230 and the circular ring 40 relative to each other.

[0046] During specific operation, after the drilling mechanism 3 processes a mounting hole on the connecting sleeve, the third motor 261 drives the driven rotating plate 260 to rotate through the driving gear 262, and the driven rotating plate 260 drives the fixing column 21 and the fixed connecting sleeve to rotate, so that the mounting hole processed on the connecting sleeve moves to the position of the positioning portion 23, and then the electric push rod 232 pulls the supporting plate 233 to move toward the connecting sleeve, and the supporting plate 233 drives the extruding plate 236 to fit with the connecting sleeve through the rectangular plate 234 and the first compression spring 235 to limit the further movement of the extruding plate 236, and at the same time, the positioning block 237 passes through the corresponding mounting hole processed on the connecting sleeve. Continue to pull, the support plate 233 will drive the pushing rod 52 to move and compress the No. 1 compression spring 235 through the rectangular plate 234, and the truncated cone end of the pushing rod 52 will contact the inclined surface of the positioning block 237 to push the positioning block 237 to move to the side away from the axis of the pushing rod 52 and fit with the inner wall of the mounting hole on the connecting sleeve. At this time, the pushing rod 52 contacts the horizontal section of the positioning block 237. Therefore, when the pushing rod 52 moves further, the positioning block 237 will remain in contact with the inner wall of the mounting hole on the connecting sleeve. Then, the fixing column 21 and the fixed connecting sleeve are driven to rotate through the driving part 26, and the positioning part 23 is driven to move synchronously at the same time until the connecting sleeve rotates to the position of the next required drilling hole.

[0047] Afterwards, the electric push rod 232 pulls the support plate 233 to move further, and the support plate 233 drives the limiting rod 42 to pass through the limiting holes 41 on the arc plate 230 and the ring 40 in sequence to limit the movement of the positioning part 23, thereby further improving the stability and processing quality of the connecting sleeve.

[0048] like Figure 1 and Figure 2As shown, the drilling portion 32 includes a fixed head 320, and two fixed heads 320 are provided at the lower end of the fixed frame 31, which are symmetrical about the fixed seat 20. A drill bit 321 is fixedly installed at the lower part of the fixed head 320. The upper ends of the symmetrical fixed heads 320 rotate and penetrate into the fixed frame 31 and are connected through belt transmission. A motor No. 322 is fixedly installed at the upper end of the fixed frame 31, and the output shaft of the motor No. 1 322 rotates and penetrates the upper part of the fixed frame 31 and is fixedly connected to one of the fixed heads 320.

[0049] like Figure 1 and Figure 2 As shown, the push-pull portion 34 includes a connecting plate 340 , the lower ends of the front-rear symmetrical shaft rods 30 are fixedly mounted with the connecting plate 340 , the lower end of the bottom plate 11 is fixedly mounted with a hydraulic cylinder 341 , and the telescopic end of the hydraulic cylinder 341 is fixedly connected to the connecting plate 340 .

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, the locking portion 33 includes a square plate 330, and the front and rear ends of the pushing plate 251 are fixedly installed with a square plate 330 with a through hole, and the lower end of the fixed frame 31 is fixedly installed with a No. 1 locking rod 331 corresponding to the through hole one by one, and the lower end of the fixed frame 31 is also fixedly installed with a No. 2 locking rod 332 which is symmetrical about the fixing seat 20 and slides with the corresponding limiting hole 41 on the corresponding ring 40.

[0051] During specific operation, the hydraulic cylinder 341 drives the shaft rod 30 to move downward through the connecting plate 340, and the shaft rod 30 drives the drilling part 32 and the locking part 33 to move downward. The No. 1 locking rod 331 of the locking part 33 will pass through the through hole on the corresponding square plate 330 to limit the movement of the corresponding pushing plate 251, and the No. 2 locking rod 332 will pass through the limiting hole 41 on the relative ring 40 to limit the rotation of the fixing column 21, so that the drilling mechanism 3, the pushing part 25 and the positioning part 23 are mutually constrained to further improve the overall stability of the connecting sleeve processing.

[0052] After the processing is completed, the drilling mechanism 3 moves up to allow the locking portion 33 to release the limit on the pushing portion 25 and the positioning portion 23, and then the pushing portion 25 moves away from the connecting sleeve, the clamping portion 24 releases the fixation of the connecting sleeve, and then the processed connecting sleeve is removed, and the above operation is repeated to continue the drilling process of the connecting sleeve.
