Description

Technical Field

[0001] This invention belongs to the field of steel structure processing technology, and in particular relates to a drilling machine for steel structure processing. Background Technology

[0002] Steel structure drilling machines are widely used in many fields such as automobile manufacturing, aerospace, electronic equipment, and construction. In order to improve processing efficiency and quality, some drilling machines will add other functions in addition to drilling. For example, a steel structure processing drilling machine disclosed in patent announcement number CN118321924B integrates a burr cleaning structure on the drilling machine, which can complete the burr cleaning work simultaneously during drilling, reducing the investment of subsequent work.

[0003] However, during the continuous operation of the drilling machine, the cutting tool, as the core processing component, is constantly in high-speed cutting and grinding contact with the steel structure material. The cutting edge will continuously experience wear and tear. This wear not only leads to a decrease in drilling accuracy (such as hole diameter deviation and hole wall roughness), but also increases the risk of tool breakage due to the reduction in cutting edge strength. Therefore, the cutting tool needs to be replaced in a timely manner according to the working conditions. At the same time, the grinding parts are replaced more frequently than the cutting tools (grinding parts are mostly made of flexible bases such as sponge and fiber cloth combined with abrasive, which are more prone to wear). Frequent manual replacement will affect the overall processing efficiency and result in poor performance. Summary of the Invention

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] like Figures 1-9As shown, a steel structure drilling machine includes a processing table 1 and an industrial control cabinet 2. The surface of the processing table 1 has a T-slot 3 for mounting fixtures. A drilling unit 4 is located above the processing table 1. The drilling unit 4 includes a fixing plate 41, with a drilling motor 42 fixed to the bottom of the fixing plate 41. A connecting post 13 is fixed to the output end of the drilling motor 42. An encoder 43 is fixed to the end of the drilling motor 42, and the rotating end of the encoder 43 is connected to the output end of the drilling motor 42. The drilling motor 42 is electrically connected to the industrial control cabinet 2. The encoder 43 can detect the rotational speed of the output end of the drilling motor 42 and calculate the real-time load state and wear degree of the tool or grinding workpiece based on this rotational speed. Specifically, when the tool or grinding workpiece is in a normal state, the drilling... The output speed of motor 42 remains stable within a preset range. However, if the cutting tool wears or chipps, or if the grinding part experiences abrasive shedding or hardening of the substrate, the grinding resistance will increase, causing the load on the drilling motor 42 to rise. Consequently, the output speed will fluctuate, decrease, or experience abnormal fluctuations. Encoder 43 transmits the real-time speed data to the industrial control cabinet 2. The industrial control cabinet 2 has preset speed threshold ranges for different working conditions. When the speed is detected to continuously deviate from the threshold or the fluctuation exceeds the set range, the industrial control cabinet 2 will automatically issue an alarm message to remind the staff to replace the cutting tool or grinding part in a timely manner to avoid affecting drilling accuracy and processing efficiency due to component failure. The speed threshold is preset based on factors such as the steel structure material to be processed, the cutting tool material, and the grinding part material.

[0035] The machining table 1 is equipped with a drive unit 5 that drives the drilling unit 4 to move. The drive unit 5 includes two support frame plates 51 fixed to the side wall of the machining table 1. A longitudinal screw drive assembly 52 is installed inside the two support frame plates 51. A gantry frame 53 is provided above the machining table 1, and the longitudinal screw drive assembly 52 drives the gantry frame 53 to move horizontally along the support frame plates 51.

A transverse screw drive assembly 55 is installed on the gantry frame 53, and the transverse screw drive assembly 55 drives the movable seat 54 to move along the strip-shaped hole. A vertical push cylinder 56 is inserted into the movable seat 54. The vertical push cylinder 56... The moving end is fixed with a pressure detection component 57 connected to the fixed plate 41. The longitudinal lead screw drive component 52, the transverse lead screw drive component 55 and the vertical push cylinder 56 are electrically connected to the industrial control cabinet 2. The side wall of the moving seat 54 is fixed with a connecting frame 58, and the triangular frame 6 is fixed at the bottom of the connecting frame 58. The connecting frame 58 is slidably connected to the side wall of the gantry frame 53. The longitudinal lead screw drive component 52 and the transverse lead screw drive component 55 both include components such as a motor, lead screw, lead screw nut, bearing, belt, and pulley. The moving end of the vertical push cylinder 56 is equipped with a displacement detector (not shown in the figure), which can monitor the position of the fixed plate 41 in real time to accurately control the position of the tool and the grinding part.

[0036] A triangular frame 6 is positioned below the drilling unit 4. A movable groove 7 is formed on the side wall of the triangular frame 6, and a chain drive assembly 8 is installed inside the movable groove 7. Several movable blocks 9 are slidably connected to the groove wall of the movable groove 7, and the chain drive assembly 8 drives the movable blocks 9 to move cyclically along the movable groove 7. Each movable block 9 has a square hole, inside which is a square slot post 10 for mounting drilling tools. The square slot post 10 is equipped with a first engaging mechanism 11 that engages with the movable blocks 9. The first engaging mechanism 11 includes two integrally formed inner protrusions 111 on the inner wall of the square slot post 10. The inner protrusions 111 are located on two opposite slot walls of the square slot post 10. A docking groove is formed on the side wall of the docking post 13, and the inner protrusions 111 and the side wall of the square slot post 10 together form a first mounting hole 1. 12. A first support block 113 is fixed inside the first mounting hole 112, and a first slide rod 114 is slidably connected to the side wall of the first support block 113. A first locking block 115 is fixed to the rod end of the first slide rod 114, and a first locking hole 116 matching the first locking block 115 is opened in the hole wall of the square hole. A slanted opening is opened on the top side of the first locking block 115 near the first locking hole 116. A miniature electromagnetic push rod 117 is fixed inside the first locking hole 116, and the movable end of the miniature electromagnetic push rod 117 faces the first locking block 115. A first support spring 118 is fixed between the first locking block 115 and the first support block 113. The miniature electromagnetic push rod 117 includes components such as an electromagnetic column, a permanent magnet, a telescopic rod, an elastic element, and a cylinder.

[0037] At least two grinding component mounting posts 12 are detachably fixed to the bottom of the square slot post 10. A docking post 13 is installed at the output end of the drilling unit 4. The square slot post 10 is equipped with a second snap-fit ​​mechanism 14, and the square slot post 10 is connected to the docking post 13 via the second snap-fit ​​mechanism 14. The second snap-fit ​​mechanism 14 includes two integrally formed external protrusions 141 on the outer sidewall of the square slot post 10. The external protrusions 141 are located on two opposite outer sidewalls of the square slot post 10. The wall of the square hole has a through groove matching the external protrusions 141. The external protrusions 141 and the sidewall of the square slot post 10 together have a second mounting hole 142. A second support block 143 is fixed inside 142, and a second slide rod 144 is slidably connected to the side wall of the second support block 143. A second locking block 145 is fixed to the end of the second slide rod 144 away from the moving block 9. A second locking hole 146 matching the second locking block 145 is opened on the side wall of the docking post 13. A second support spring 147 is fixed between the second locking block 145 and the second support block 143. An electromagnetic component 148 is fixedly inserted into the groove wall of the through groove. An iron block 149 is fixed to the end of the second slide rod 144 near the electromagnetic component 148. When the electromagnetic component 148 is energized, it will generate a magnetic attraction force on the iron block 149.

[0038] The correction unit 15 is located on one side of the triangular frame 6. The correction unit 15 includes a fixed frame 151 fixed to the side wall of the gantry frame 53. A horizontal push cylinder 152 is inserted into the side wall of the fixed frame 151, and a correction plate 153 is fixed to the movable end of the horizontal push cylinder 152. A trapezoidal groove 154 is opened on the side wall of the correction plate 153 near the triangular frame 6. A power supply component 16 connected to the moving block 9 on the same side is installed in the trapezoidal groove 154. The miniature electromagnetic push rod 117 and the electromagnetic component 148 are both electrically connected to the industrial control cabinet 2 through the power supply component 16. The power supply assembly 16 includes a fixed power supply base 161 fixed to the bottom of the trapezoidal groove 154, and a movable power supply base 162 fixed to the side wall of the movable block 9. After the fixed power supply base 161 and the movable power supply base 162 are connected, the miniature electromagnetic push rod 117 and the electromagnetic component 148 on the same side are electrically connected to the industrial control cabinet 2. The side walls of the fixed power supply base 161 and the movable power supply base 162 are provided with conductive contacts. After the movable block 9 is aligned with the correction plate 153, the conductive contacts of the fixed power supply base 161 and the movable power supply base 162 make contact with each other and conduct electricity.

[0039] The two inclined walls of the trapezoidal groove 154 are provided with grooves at the ends away from the fixed power supply base 161, and a pressure switch 17 is fixed inside the grooves. The pressure switch 17 is electrically connected to the industrial control cabinet 2. When the pressure switch 17 is squeezed by external pressure, its moving contact will close, and at this time the pressure switch 17 will send an electrical signal back to the industrial control cabinet 2.

[0040] The movable block 9 has L-shaped grooves at both corners away from the triangular frame 6, and a rotating rod 18 is rotatably connected inside the L-shaped groove. By adding a rotatable rotating rod 18 at the inflection point of the movable block 9, the wear when the movable block 9 contacts the trapezoidal groove 154 can be reduced.

[0041] The operating principle of the present invention is explained as follows: The fixture is installed in the T-slot 3, and then the steel structure workpiece to be processed is installed in the fixture. The workpiece is clamped and fixed by the fixture. Then the industrial control cabinet 2 is started, and the processing program corresponding to the workpiece is selected. Then the processing of the workpiece is started through the industrial control cabinet 2.

[0042] At this time, the industrial control cabinet 2 will control the longitudinal lead screw drive assembly 52 and the transverse lead screw drive assembly 55 to work according to the program. The longitudinal lead screw drive assembly 52 can drive the gantry 53 to move longitudinally, and the transverse lead screw drive assembly 55 can drive the moving seat 54 to move laterally (both the longitudinal lead screw drive assembly 52 and the transverse lead screw drive assembly 55 include components such as motors, lead screws, lead screw nuts, bearings, belts, and pulleys). After moving to the drilling point, the vertical push cylinder 56 drives the drilling motor 42 to move downward. At this time, the drilling motor 42 will be driven by the docking column 13. The square slot column 10, which is already clamped on the outside of the docking column 13, moves down. At the same time, the industrial control cabinet 2 controls the drilling motor 42 to work. The drilling motor 42 drives the drilling tool installed at the bottom of the square slot column 10 to rotate through the docking column 13 and the square slot column 10, so that drilling work can be performed on the steel structure. Similarly, if a grinding part mounting column 12 is installed at the bottom of the square slot column 10, the grinding part can be fixed at the bottom of the grinding part mounting column 12. The drilling motor 42 drives the grinding part mounting column 12 to drive the grinding part to rotate, so that the surface of the workpiece can be ground or polished.

[0043] When it is necessary to change drilling tools or grinding parts, the industrial control cabinet 2 controls the movable end of the vertical push cylinder 56 to move back, and at the same time controls the two electromagnetic components 148 to work. When the vertical push cylinder 56 drives the square groove column 10 to move back to the bottom of the moving block 9 through the docking column 13, the lower side wall of the square hole of the moving block 9 will be squeezed by the inclined opening of the first locking block 115, so that the first locking block 115 retracts into the first mounting hole 112. When the first locking block 115 moves to the position of the first locking hole 116, under the action of the first support spring 118, the first locking block 115 will quickly The first locking block 115 snaps into the first locking hole 116. At the same time, when the second locking block 145 moves to the position of the electromagnetic component 148, the electromagnetic component 148 generates a magnetic attraction force on the iron block 149 due to the power of the electromagnetic component 148. Therefore, the second locking block 145 will be pulled back into the second mounting hole 142 by the iron block 149 through the second sliding rod 144. At this time, the second locking block 145 disengages from the second locking hole 146. Therefore, the square slot post 10 separates from the docking post 13. Due to the locking action of the first locking block 115 and the first locking hole 116, the square slot post 10 is fixed in the square hole of the moving block 9.

[0044] Subsequently, the industrial control cabinet 2 de-energizes the electromagnetic component 148 and controls the horizontal push cylinder 152 to move back. At this time, the horizontal push cylinder 152 drives the correction plate 153 to move back and disengage from the moving block 9. Then, the industrial control cabinet 2 controls the chain drive assembly 8 to work. The chain of the chain drive assembly 8 drives each moving block 9 to move along the moving groove 7 of the triangular frame 6 (the chain drive assembly 8 includes components such as a motor, chain, sprocket, and bearings). After the next tool or grinding part to be used moves to below the docking post 13, the chain drive assembly 8 stops working. Then, the industrial control cabinet 2 controls the horizontal push cylinder 152 to work again. 152 drives the correction plate 153 to move towards the moving block 9. When the moving block 9 deviates slightly, one end of it will first contact one side of the inclined groove wall of the trapezoidal groove 154. Under the squeezing action of the inclined groove wall of the trapezoidal groove 154, the moving block 9 will move back. For example, if the moving block 9 does not reach the designated position after it stops moving, one end of the moving block 9 will be squeezed by the inclined groove wall of the trapezoidal groove 154, and the moving block 9 will continue to move a certain distance, eventually making the moving block 9 return to the preset position. At this time, the conductive contacts of the fixed power supply base 161 and the movable power supply base 162 remain in contact.

[0045] Then, the industrial control cabinet 2 controls the vertical push cylinder 56 to drive the docking post 13 downward, and at the same time controls the electromagnetic component 148 to work again, moving the second locking block 145 into the second mounting hole 142. After the docking post 13 is inserted into the square slot post 10, the electromagnetic component 148 is de-energized. At this time, under the action of the second support spring 147, the second locking block 145 is inserted into the second locking hole 146, completing the docking of the square slot post 10 and the docking post 13. Then, the industrial control cabinet 2 controls the micro electromagnetic push rod 117 to work. The micro electromagnetic push rod 117 will push the first locking block 115 to disengage from the first locking hole 116. At the same time, the industrial control cabinet 2 controls the vertical push cylinder 56 to continue working, so that the docking post 13 continues to move downward. At this time, since the first locking block 115 is separated from the first locking hole 116 and the second locking block 145 is inserted into the second locking hole 146, the docking post 13 will drive the square slot post 10 to move downward, and then drilling or grinding work can begin.

[0046] During the process of the correction plate 153 correcting the movement block 9, if the deviation of the movement block 9 is too large, one end of the movement block 9 will first contact the pressure switch 17 at the trapezoidal groove 154. Under the action of the contact pressure, the moving contact of the pressure switch 17 will close. At this time, the pressure switch 17 will send an electrical signal to the industrial control cabinet 2, and the industrial control cabinet 2 will issue an audible and visual alarm to remind personnel to inspect the chain drive assembly 8, so as to avoid the movement block 9 from being too offset and affecting the normal switching of tools and grinding parts.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
