Description

1. Technical field

[0002] The invention belongs to the technical field of lock preparation machinery, and in particular relates to an automatic processing machine tool for a die-casting lock shell. 2. Background technology

[0004] Die-casting lock housing is a lock housing manufactured by die-casting technology. It is widely used in door locks and cabinet locks due to its low manufacturing cost and short production cycle. Figure 1 As shown, the lock shell is gourd-shaped, with two symmetrically arranged bosses cast in the middle of the gourd. The big head of the gourd is processed with a through lock core hole, the side of the small head of the gourd is processed with a number of pin holes, and the end face of the small head of the gourd is processed with a pin hole. The principle of lock safety protection is that since the lock core hole is equipped with a lock core, a lock with safety protection is produced by combining pins of different lengths and numbers. Due to the die-casting process adopted, the lock core hole, pin hole and pin hole of the lock shell need to be processed twice to ensure their accuracy requirements. The traditional processing method adopts a single-process mode, that is, the lock core hole, pin hole and pin hole of the lock shell need to be processed by at least one equipment each, which has low production efficiency and is difficult to ensure the processing accuracy of the lock shell due to repeated positioning and secondary clamping. In addition, this type of lock shell has a large shape, a short turnover cycle between processes, and is also very inconvenient. (III) Summary of the invention

[0045] The accompanying drawings show a specific embodiment of the present invention. The embodiment comprises a frame 1, a turntable 3 is installed in the middle of the bottom plate 2 of the frame 1, six sets of evenly distributed fixtures 4 are mounted on the turntable 3, a rotary table 301 is installed at the lower part of the turntable 302, and a feeder 5, a ball hole drilling part 6, a pin hole drilling part 7, a lock core hole drilling part 8, a burr punching part 9 and a discharger 10 are fixed around the turntable 3 at positions corresponding to the fixtures 4, the feeder 5, the ball hole drilling part 6, the pin hole drilling part 7, the lock core hole drilling part 8, the burr punching part 9 and the discharger 10 are sequentially distributed in a counterclockwise direction, and the six sets of evenly distributed fixtures 4 are in a loose state when they run to the feeder 5 and the discharger 10, and are in a clamped state when they are in the ball hole drilling part 6, the pin hole drilling part 7 and the lock core hole drilling part 8. The processing process of the present invention is that the lock shell 11 stored in the feed part 5 enters the clamp part 4 and is clamped. As the turntable 302 rotates, the lock shell 11 is transported to the ball drilling part 16, the pin drilling part 7, the lock core drilling part 8, and the burr punching part 9 for processing. The unloading guide column 1011 inserted into the lock core hole 14 of the lock shell 11 at the unloading station drags the lock shell 11 to the drop hopper and then slides out of the machine. The bracket part includes a frame 1, a bottom plate 2 and a fence 19. The bottom plate 2 is fixed on the frame 1. The fence 19 is installed around the frame 1. The side of the fence 19 is installed with an electric box 18 and a display screen 20. The electric box 18 is equipped with a PLC. The display screen 20 installed on the machine can control the feed part 5, the ball drilling part 6, the pin drilling part 7, the lock core drilling part 8, the burr punching part 9 and the unloading part 10 to work individually or synchronously.

[0046] The main components of the turntable part 3 include a rotary table 301, a mechanical valve support plate 305, a turntable 302, and an air distribution pipe fixing seat 312. The lower part of the rotary table 301 is installed on a rotary table heightening seat, and this rotary table heightening seat is fixed on the base plate 2. A driving motor 317 for driving the shaft to rotate is installed on one side of the rotary table 301. This direct-connection transmission method has the advantages of saving space and high transmission efficiency. It can be imagined that the use of a synchronous belt or chain can also achieve the purpose of driving the worktable to rotate. A mechanical valve support plate 305 is installed above the rotary workbench 301. The mechanical valve support plate 305 has a cam-like shape, a part of its outer circumference is a circular contour, and the other part is processed with a notch 306. A boss is processed at one end of the notch 306, and a mechanical valve paddle 307 is installed on the boss. The position of the mechanical valve paddle 307 is close to the feed part 5. One end of the mechanical valve paddle 307 is hinged to the mechanical valve support plate 305 through a paddle pin, and the other end is installed with a paddle rod 308. One end of the paddle rod 308 is equipped with a paddle cylinder joint 309. This paddle cylinder joint 309 is installed on the cylinder rod of the paddle cylinder 310 on the paddle movable seat 311, and the paddle movable seat 311 is fixed on the base plate 2. In addition, six mechanical valves 303 arranged at equal intervals are installed under the turntable 302, and the rollers 304 on the six mechanical valves 303 are arranged in the same direction. The center lines of the rollers 304 of the assembled mechanical valves 303 coincide with the center plane of the thickness direction of the mechanical valve support plate 305. When the turntable 302 rotates, the six mechanical valves 303 on the turntable 302 will rotate around the mechanical valve support plate 305. When the rollers 304 on the mechanical valve 303 contact the circular contour on the mechanical valve support plate 305, the mechanical valve 303 will open, thereby controlling the corresponding clamping cylinder 415 to operate and clamp the lock shell 11. It can be seen from the figure that the circular contour of the mechanical valve support plate 305 corresponds to the drilling ball hole portion 6, the drilling pin hole 7, the core drilling hole portion 8 and the burr punching portion 9, that is, when the turntable 302 rotates to the above-mentioned four workstations, the workpiece will be in a clamped state. A turntable 302 is also installed above the rotary worktable 301. Six sets of fixture parts 4 arranged at equal intervals are installed, and a circular recess is processed in the middle of the turntable 302, and an air pipe fixing seat 312 is installed on the recess. The outer circumference of the air pipe fixing seat 312 is processed with evenly distributed threaded holes for installing quick-connect connectors, and the threaded holes are used to connect the corresponding clamping cylinder 415. At the same time, one end face of the air pipe fixing seat 312 is also processed with a threaded hole for installing a rotary joint 313, and a rotary joint bracket 314 is arranged on the outside of the rotary joint 313. The front section of the above-mentioned rotary joint bracket 314 is processed with a notch, and the notch just clamps the outside of the rotary joint 313 to prevent the air pipe on the rotary joint 313 from rotating when the turntable 302 rotates, causing entanglement. The rotary joint bracket 314 is fixed on the rotary joint bracket extension rod 315, and the rotary joint bracket extension rod 315 is installed on the rotary joint fixing plate 316 fixed on the base of the drill lock core hole.

[0047] Each set of fixture parts 4 includes a fixture base plate 401, a linear guide rail 402 installed at the front end of the fixture base plate 401, a clamping sliding seat 407 installed in the middle of the fixture base plate 401, and a clamping cylinder seat installed at the rear end of the fixture base plate 401. The length of the linear guide rail 402 installed at the front end of the fixture base plate 401 is substantially the same as the width of the fixture base plate 401. A clamping slider 403 is installed on the linear guide rail 402. Clamping insert seats 404 are respectively installed on both sides of the upper part of the clamping slider 403. The two clamping insert seats 404 are symmetrically arranged. Stopper is processed on one of the opposite surfaces of the two clamping insert seats 404. The stoppers of the two clamping insert seats 404 are respectively equipped with an upper clamping insert seat 405 and a lower clamping insert seat 406. The upper clamping insert seat 405 and the lower clamping insert seat 406 on the left are both processed with an arc of the same radius as the outer diameter of the lock shell 11 and a concave platform for avoiding the lock shell ear 15. The upper clamping insert seat 405 and the lower clamping insert seat 406 on the right are also processed with an arc of the same radius as the outer diameter of the lock shell 11 and a concave platform for avoiding the lock shell ear 15. There is a straight line extending at the arc of the upper clamping insert seat 405 and the lower clamping insert seat 406 on the left, which is used to position the lock shell 11 when performing the feeding action. A clamping slide rail 408 is installed on the upper part of the clamping sliding seat 407 installed in the middle of the clamp base plate 401, and a clamping slider 403 is installed on the clamping slide rail 408. The clamping slider 403 is equipped with a clamping guide plate 409. One end of the clamping guide plate 409 is processed with a step groove, and a clamping cylinder joint 413 is installed in the groove. A clamping bolt 414 is installed in the stepped clamping cylinder joint 413, and the clamping bolt 414 is connected to the cylinder rod of the clamping cylinder 415. After the clamping bolt 414 is tightened, the clamping cylinder joint 413 is tightly pressed against the cylinder rod of the clamping cylinder 415. Of course, the clamping bolt 414 and the clamping cylinder joint 413 can be made into one piece, but the preferred method has lower production cost and shorter processing time.The other end of the clamping guide plate 409 is processed with an inner arc profile to avoid the chuck of the drilling lock core hole 8. In addition, the clamping cylinder seat installed at the rear end of the clamp base plate 401 is L-shaped. The upper end of this clamping cylinder seat is equipped with a clamping cylinder 415, and the lower end is fixed on the clamp base plate 401. A step is processed on one surface of the clamp base plate 401, and the step cooperates with the notch on the turntable 302. Six grooves are also processed on the surface of the clamp base plate 401. A clamp front and rear adjustment block 417 is also fixed at one end of the clamp base plate 401 for adjusting the radial position of the clamp base plate 401 on the turntable 302. A threaded hole and a light hole, a bolt is installed in each of the threaded hole and the light hole, the bolt in the light hole is fixed in the bolt on the circumferential surface of the turntable 302, the bolt in the light hole can move the clamp base plate 401 toward the center of the turntable 302, and the bolt in the threaded hole can move the clamp base plate 401 away from the center of the turntable 302. The above-mentioned clamping sliding seat 407 is also processed with 4 long grooves, and a clamping sliding seat left and right adjustment block 416 is installed at each end of the above-mentioned clamping sliding seat 407. The clamping sliding seat left and right adjustment block 416 is processed with threaded holes to adjust the left and right position of the clamping sliding seat 407 on the clamping base plate 401. A recess is machined on the plane where the clamping guide plate 409 contacts the clamping slider 403, and the recess is just stuck on the clamping slider 403. In addition, two guide grooves 410 arranged in a V-shape with a center direction are machined on both sides of the recess of the clamping guide plate 409. A clamping bearing 411 is assembled in each groove, and a bearing support rod 412 is installed in the inner hole of each clamping bearing 411. Each bearing support rod 412 is respectively fixed on the clamping insert seat 404 on both sides. The clamping action of the above-mentioned clamp part 4 is as follows: when the mechanical valve 303 controls the action of the clamping cylinder 415, the cylinder rod of the clamping cylinder 415 extends to drive the clamping guide plate 409 forward. Since the lower part of the clamping guide plate 409 is processed with a V-shaped guide groove 410, the clamping bearings 411 fixed on the bearing support rod 412 are close to each other, that is, the two clamping block seats 404 are also close to each other, and then the two upper clamping block seats 405 installed on the two clamping block seats 404 are close to each other, thereby clamping the lock shell 11 between the two upper clamping block seats 405.

[0048] The components of the feed part 5 include a feed seat 508 and a positioning needle block 512 fixed on the feed push block 511, a positioning needle 513 is installed on the positioning needle block 512, and the number of the positioning needles 513 is two. The two positioning needles 513 are respectively aligned with the uppermost and lowermost pin holes 12 of the lock shell 11. A long groove is processed on the top of the feed seat 508, and the lock shell 11 can slide in this long groove. The feed seat 508 is placed with vertically stacked lock shells 11.
