Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to an automatic positioning drilling device for die-cast parts. Background Technology

[0002] Die casting is a metal part formed by injecting molten metal into a mold cavity under high pressure using a die casting process. It is widely used in machinery manufacturing, home appliances, and industrial equipment. After die casting is completed, subsequent machining processes such as drilling are usually required to meet assembly and connection requirements. This necessitates the important role of the intelligent manufacturing equipment industry.

[0003] When drilling die-cast parts, it is usually necessary to first place the die-cast parts on a fixture or worktable for positioning. Currently, the positioning method is usually done by manually placing and adjusting the position of the die-cast parts. This method is not only inefficient, but also easily affected by the operator's experience and operating habits, resulting in unstable positioning accuracy and thus the problem of drilling position deviation. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic positioning drilling device for die-cast parts to solve the problem of low positioning accuracy before drilling in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a worktable is included, a drilling head is installed inside the worktable, a positioning device is installed below the drilling head, and the drilling head is connected to a control system; a servo motor is installed on one side of the drilling head, and the servo motor controls the lifting and moving of the drilling head to place the die-casting part on the positioning device. The positioning device automatically positions the die-casting part to facilitate subsequent drilling.

[0006] The positioning device includes a base cylinder and a preliminary positioning assembly. The base cylinder is installed below the drill bit, and a support plate is slidably installed inside the base cylinder. A clamping assembly is slidably installed on the support plate, and a drive assembly is installed on the support plate. One end of the drive assembly is installed on the preliminary positioning assembly, and the other end of the drive assembly is installed on the clamping assembly. When the die-casting part is placed on the support plate, the support plate slides inside the base cylinder under the action of gravity. The support plate drives the preliminary positioning assembly to perform preliminary positioning of the die-casting part, so that one side of the datum surface of the die-casting part can be aligned with the positioning datum structure. After one side is positioned, the drive assembly is controlled to start the clamping assembly to correct the position of the other side of the die-casting part, so that the die-casting part moves closer to the center datum position, realizing the overall alignment of the die-casting part, and clamping the die-casting part to prevent it from moving during subsequent drilling.

[0007] The initial positioning assembly includes an alignment element that slides on a support plate. A first contact element is mounted on the alignment element, and the first contact element and clamping assembly are connected by a pipe. A fixing element is mounted on one side of the alignment element, and the fixing element slides on the support plate. When the die-cast part is placed on the support plate, the die-cast part causes the support plate to slide within the bottom cylinder. The support plate causes the alignment element to move towards each other, and the alignment element causes the first contact element to move towards each other. The first contact element pushes the die-cast part towards the center until the first contact element presses against both sides of the die-cast part. The control drive assembly then moves the fixing element to fix the position of the support plate.

[0008] The clamping assembly includes a transmission element that slides on a support plate and has a second contact element mounted on it. The transmission element drives the second contact element to move, and the second contact element aligns the other side of the die casting while clamping it to prevent the die casting from loosening during subsequent drilling.

[0009] The support plate includes a fixed plate, which is installed inside the bottom cylinder. A floating plate is slidably installed inside the bottom cylinder. Alignment elements and transmission elements slide on the floating plate. A guide post is installed on one side of the floating plate. A first elastic element is installed on the guide post. One end of the first elastic element is installed on the fixed plate. The fixed element slides on the fixed plate. The first elastic element includes a first spring. When the die-cast part is placed on the floating plate, the die-cast part drives the floating plate to move closer to the fixed plate inside the bottom cylinder. The floating plate drives the guide post to move closer to the fixed plate. The guide post drives the first spring to compress.

[0010] The drive assembly includes a lateral drive element mounted on a fixed plate, a longitudinal drive element mounted on one side of the lateral drive element, and a transmission element mounted on one side of the longitudinal drive element. The lateral drive element is used to drive the movement of both the fixed and transmission elements.

[0011] The alignment element includes a first rack mounted on the bottom cylinder. A first rotating shaft is rotatably mounted on the floating plate, with a first gear mounted at one end of the first rotating shaft. The first rack and the first gear mesh with each other, and a second gear is mounted at the other end of the first rotating shaft. An L-shaped plate is slidably mounted on the floating plate. A first contact element is mounted at one end of the L-shaped plate, and a second rack and a push plate are mounted at the other end of the L-shaped plate. The second rack and the second gear mesh with each other. When the floating plate moves towards the fixed plate within the bottom cylinder, the floating plate drives the first rotating shaft to move towards the fixed plate. The first rack drives the first gear to rotate, which in turn drives the first rotating shaft to rotate. The first rotating shaft then drives the second gear to rotate, which in turn drives the second rack to move towards the second gear. The second rack then drives the L-shaped plate to move towards the second gear.

[0012] The first contact element includes a first housing mounted on an L-shaped plate. A first piston plate is slidably mounted inside the first housing. A first push block is mounted on one side of the first piston plate, and a second elastic element is mounted on the other side of the first piston plate. One end of the second elastic element is installed inside the first housing. The second elastic element includes a second spring. Hydraulic oil fills the space between the first piston plate and the first housing. The L-shaped plate drives the first housing to move closer to the die-cast part, and the first housing drives the first push block to push the die-cast part centripetally until both first push blocks on both sides press against the die-cast part.

[0013] The fixing element includes a conical block mounted on a floating plate. A wedge block is slidably mounted on the fixing plate, and a first lead screw is rotatably mounted on the wedge block. A first bevel gear is mounted on the first lead screw. When both first push blocks on both sides press against the die-cast part, the floating plate stops moving, and the dual-axis motor starts. One end of the dual-axis motor drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear drives the first lead screw to rotate, and the first lead screw drives the two wedge blocks to move towards each other until the wedge blocks press against the conical block, fixing the position of the floating plate. After drilling is completed, one end of the dual-axis motor drives the second bevel gear to reverse, which in turn drives the first lead screw to reverse. The first lead screw drives the two wedge blocks to move away from each other, releasing the conical block and pressing it against the push plate. The wedge block drives the push plate to move away from each other, which in turn drives the L-shaped plate to move away from each other. The L-shaped plate moves the first contact element away from the die-cast part surface, facilitating the repositioning of the alignment element.

[0014] The transmission element includes a second lead screw that rotates on a floating plate. A sliding seat is slidably mounted on the second lead screw, and a T-shaped plate is slidably mounted on the floating plate. A second contact element is mounted on the T-shaped plate, and a limit plate is mounted on the floating plate. A fourth elastic element, including a fourth spring, is installed between the limit plate and the T-shaped plate. The rotation of the second lead screw causes the two sliding seats to move towards each other, which in turn causes the T-shaped plate to move towards each other, and the T-shaped plate causes the second contact element to move towards each other.

[0015] Both the first and second lead screws have two threads with different directions of rotation.

[0016] The second contact element includes a second housing mounted on a T-shaped plate. A second piston plate is slidably mounted inside the second housing. A second push block is mounted on one end of the second piston plate, and a pull plate is mounted on the other end. A fifth elastic element is installed between the second piston plate and the second housing. The second housing and the first housing are connected by a pipe. The fifth elastic element includes a fifth spring. The space between the second piston plate and the second housing is filled with hydraulic oil. When the sliding seat moves away from the pull plate, the fifth spring stretches, causing the second piston plate to move closer to the second push block. The second piston plate causes the second push block to extend, at which point the hydraulic oil in the first housing is drawn into the second housing. The first piston plate retracts, facilitating the second push block to adjust the position of the die-casting. When the second push block moves onto the die-casting, the die-casting presses against the second push block, causing the die-casting to move away from the die-casting. At this point, the hydraulic oil in the second housing is forced into the first housing, the first piston plate unfolds, and the first and second piston plates press against the die-casting, clamping it.

[0017] The lateral drive element includes a first drive member, one end of which is equipped with a second bevel gear that meshes with the first bevel gear. The other end of the first drive member is equipped with a third bevel gear. A rotating cylinder is rotatably mounted on a fixed plate, and a fourth bevel gear is mounted on the rotating cylinder; the third and fourth bevel gears mesh with each other. The first drive member includes a dual-axis motor, one end of which drives the second bevel gear to rotate, and the other end of which drives the third bevel gear to rotate.

[0018] The longitudinal drive element includes a second rotating shaft that slides within a rotating cylinder. A support block is mounted on the second rotating shaft and a second lead screw. A positioning block is mounted on the second rotating shaft. A sixth bevel gear is mounted at one end of the second rotating shaft, and a fifth bevel gear is mounted on the second lead screw. The sixth and fifth bevel gears mesh. When the floating plate moves, the floating plate drives the second lead screw to move, which in turn drives the support block to move. The support block then causes the second rotating shaft to slide within the rotating cylinder. The third bevel gear drives the fourth bevel gear to rotate, which in turn drives the rotating cylinder to rotate. The rotating cylinder then drives the second rotating shaft to rotate, which in turn drives the sixth bevel gear to rotate, which in turn drives the fifth bevel gear to rotate, and finally, the fifth bevel gear drives the second lead screw to rotate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention employs an automatic positioning device. When the die-cast part is placed on the worktable, the initial positioning component performs preliminary positioning of the die-cast part, aligning one side of the die-cast part with the positioning reference structure, thereby completing the initial position correction of the die-cast part. After completing the positioning of one side, the clamping component corrects the position of the other side of the die-cast part, bringing the die-cast part closer to the center reference position, achieving overall position alignment of the die-cast part. Through the coordinated action of the positioning mechanisms on both sides, the die-cast part can achieve automatic centering and positioning on the worktable, while simultaneously clamping the die-cast part to maintain a stable state during drilling, avoiding hole position deviations caused by workpiece loosening or displacement.

[0045] Working principle of the invention:

[0046] When in use, the die-cast part is manually placed on the floating plate 142. The die-cast part drives the floating plate 142 to move towards the fixed plate 141 within the bottom cylinder 11. The floating plate 142 drives the guide column to move towards the fixed plate 141. The guide column compresses the first spring. At the same time, the floating plate 142 drives the first rotating shaft to move towards the fixed plate 142. The first rack 1211 drives the first gear 1212 to rotate. The first gear 1212 drives the first rotating shaft to rotate. The first rotating shaft drives the second gear 1213 to rotate. The second gear 1213 drives the second rack 1215 to move towards the second gear 1213. The second rack 1215 drives the L-shaped plate 1214 to move towards the second gear 1213. The L-shaped plate 1214 drives the first housing 1221 to move towards the die-cast part. The first housing 1221 drives the first pushing block 1223 to push the die-cast part towards the center until the first pushing blocks 1223 on both sides are pressed on the die-cast part.

[0047] When the floating plate 142 stops moving, the dual-axis motor is started. One end of the dual-axis motor drives the second bevel gear to rotate, the second bevel gear drives the first bevel gear to rotate, the first bevel gear drives the first lead screw 1233 to rotate, and the first lead screw 1233 drives the two wedge blocks 1232 to move towards each other until the wedge blocks 1232 press on the conical block 1231, fixing the position of the floating plate 142 and preventing the die-casting part from moving during drilling.

[0048] The dual-axis motor is started, and the other end of the dual-axis motor drives the third bevel gear 1512 to rotate. The third bevel gear 1512 drives the fourth bevel gear 1513 to rotate. The fourth bevel gear 1513 drives the rotating cylinder 1514 to rotate. The rotating cylinder 1514 drives the second rotating shaft 1523 to rotate. The second rotating shaft 1523 drives the sixth bevel gear 1522 to rotate. The sixth bevel gear 1522 drives the fifth bevel gear 1521 to rotate. The fifth bevel gear 1521 drives the second lead screw 1311 to rotate. The rotation of the second lead screw 1311 drives the two sliding seats 1313 to move towards each other. The sliding seats 1313 drive the T-shaped plate 1312 to move towards each other. The T-shaped plate 1312 drives the second contact element 132 to move towards each other.

[0049] When the sliding seat 1313 moves away from the pull plate 1325, the fifth spring stretches and drives the second piston plate 1322 to move closer to the second push block 1323. The second piston plate 1322 drives the second push block 1323 to extend. At this time, the hydraulic oil in the first housing 1221 is drawn into the second housing 1321, and the first piston plate 1222 retracts. At this time, the first piston plate 1222 moves away from the surface of the die-cast part, making it easier for the second push block 1323 to adjust the position of the die-cast part. When the second push block... When 1323 moves onto the die-cast part, the die-cast part presses on the second push block 1323. The die-cast part drives the second push block 1323 to move away from the die-cast part. At this time, the hydraulic oil in the second housing 1321 is pushed back into the first housing 1221. The first piston plate 1222 unfolds and the first piston plate 1222 and the second piston plate 1322 press on the die-cast part, clamping the die-cast part. The servo motor and the drill head 2 are started. The servo motor drives the drill head 2 to drill holes in the positioned die-cast part.

[0050] After drilling is completed, one end of the dual-axis motor is reversed, causing the sliding seat 1313 to drive the pull plate 1325 back to the initial position. The other end of the dual-axis motor is then reversed, causing the second bevel gear to reverse. The second bevel gear then reverses the first lead screw 1233, causing the first lead screw 1233 to move two wedge blocks 1232 in opposite directions, releasing the conical block 1231 and pressing it onto the push plate 1216. The wedge blocks 1232 then move the push plate 1216 in opposite directions, which in turn moves the L-shaped plate 1214 in opposite directions. The L-shaped plate 1214 then moves the first contact element 122 away from the surface of the die-cast part. At this point, the die-cast part is manually removed, and the initial positioning assembly 12 is reset.
