Description

Technical Field

[0001] The present invention relates to the technical field of numerical control machining, and in particular to an integrated numerical control machining device. Background Art

[0002] CNC machining equipment is a type of machining equipment that uses digital information for control. It controls the movement and machining process of machine tools through computer programming. CNC machining equipment can automatically complete various complex machining tasks according to pre-programmed programs. It has the characteristics of high precision, high efficiency, high automation and high flexibility, and can significantly improve production efficiency and product quality.

[0003] In current practical applications, most traditional CNC machining equipment adopts a single electric chuck machining mode. After the workpiece is processed, it is necessary to load and unload the workpiece on the electric chuck. During this loading and unloading operation, the CNC machining equipment has to suspend the machining process. This link takes a long time, which makes it difficult to effectively improve the CNC machining efficiency of the workpiece. Summary of the invention

[0004] The present invention relates to an integrated CNC machining equipment, which solves the problem that the existing CNC machining equipment, in actual application, mostly adopts a single electric chuck machining mode, and after the workpiece machining is completed, a single workpiece loading and unloading operation needs to be performed. During the workpiece loading and unloading operation, the CNC machining equipment is in a suspended machining state, and the required processing time is relatively long, making it difficult to effectively improve the CNC machining efficiency of the workpiece.

[0005] The first aspect of the present invention provides an integrated CNC machining equipment, specifically comprising: a supporting base, an anti-chip top cover, a motor, a driving turntable, an active pinion, a driven large gear, a guide bracket, a limit locking pin, a rotating top seat and an electric chuck; the supporting base is fixedly mounted on the platform of the CNC machining equipment, and an anti-chip top cover is fixedly mounted on the top of the supporting base; the motor is fixedly mounted on the bottom of the supporting base, and a driving turntable is connected to the driving shaft of the motor, and the driving turntable is located on the top of the supporting base; the driving pinion is connected to the bottom of the driving turntable, and the driven large gear is connected to the top of the supporting base, and the driving pinion is connected to the driven large gear; the top of the supporting base is fixedly connected, and a limit locking pin is connected inside the guide bracket, one end of the limit locking pin is connected to the driving turntable, and the other end of the limit locking pin is connected to the driven large gear; the top of the driven large gear is fixedly connected to a rotating top seat, and the rotating top seat is located on the top of the anti-chip top cover, and two electric chucks are symmetrically mounted on the top of the anti-chip top cover.

[0006] Furthermore, the driven large gear is rotatably connected to the support base, the driving small gear is meshed with the driven large gear for transmission, the transmission ratio of the driving small gear to the driven large gear is 2:1, the motor drives the driving turntable to rotate one circle, the driving turntable drives the driving small gear to rotate one circle synchronously, the driving small gear drives the driven large gear to rotate half a circle, and the driven large gear drives the rotating top seat to rotate half a circle synchronously, and the two electric chuck positions are switched to transfer the unprocessed workpiece to the processing area, and the processed workpiece is transferred to the loading and unloading area.

[0007] Furthermore, the limit lock pin is T-shaped, and the limit lock pin is composed of a main pin handle, a movable pin head and a No. 2 spring. A guide slide hole is provided on the top of the guide bracket, and the limit lock pin is slidably connected to the guide slide hole.

[0008] Furthermore, a linkage sliding hole is arranged inside the kingpin handle, an eccentric protrusion is arranged on the top of the driving turntable, and the eccentric protrusion is slidably connected in the linkage sliding hole.

[0009] Furthermore, the kingpin handle is slidably connected to the movable pin head, two square sliding blocks are symmetrically arranged outside the kingpin handle, and two square sliding holes are symmetrically arranged outside the movable pin head, and the square sliding blocks are slidably connected in the square sliding holes.

[0010] Furthermore, an insert rod is provided inside the movable pin head, and the end of the insert rod is slidably inserted in the main pin handle. The No. 2 spring is sleeved on the outside of the insert rod, one end of the No. 2 spring contacts the main pin handle, and the other end of the No. 2 spring contacts the movable pin head.

[0011] Furthermore, two positioning grooves are symmetrically arranged on the outside of the top of the driven large gear, and the end of the movable pin head is slidably inserted in the positioning groove. When the limit lock pin moves outward, the end of the movable pin head is separated from the positioning groove, and the driven large gear is unlocked, so that the two electric chuck positions can be rotated and switched. When the limit lock pin moves inward, the end of the movable pin head contacts the outer wall of the driven large gear, and the No. 2 spring is compressed and stored under the influence of the thrust. After the driven large gear is filled with half a circle, the positioning groove and the guide slide hole are precisely connected, and the movable pin head moves inward under the influence of the thrust of the No. 2 spring, so that the end of the movable pin head is inserted in the positioning groove, thereby locking and fixing the driven large gear.

[0012] Furthermore, two fixed blocks and two arc-shaped rods are symmetrically arranged at the bottom of the driving turntable, and both ends of the arc-shaped rods are connected to the two fixed blocks. Two arc-shaped movable holes and two through holes are symmetrically arranged inside the active pinion, and the arc-shaped movable holes are connected to the through holes. The fixed blocks are slidably connected to the arc-shaped movable holes, and the arc-shaped rods slide through the through holes.

[0013] Furthermore, two No. 1 springs are mounted on the outside of the arc rod, one end of the No. 1 spring is in contact with the active pinion, and the other end of the No. 1 spring is in contact with the fixed block. During the process of the movable pin head end separating from the positioning groove, the driven large gear is not unlocked, the active small gear stops rotating, and the driving turntable rotates alone. The No. 1 spring is compressed and accumulates force under the influence of the thrust. When the movable pin head end separates from the positioning groove, the driven large gear is unlocked, and the active small gear rotates and resets under the influence of the thrust of the No. 1 spring. The driving turntable drives the active small gear to rotate, and the active small gear further drives the driven large gear to rotate.

[0014] The present invention provides an integrated CNC machining device, which has the following beneficial effects:

[0015] When the present invention is in use, the motor drives the driving turntable to rotate one circle, the driving turntable drives the active small gear to rotate one circle synchronously, the active small gear drives the driven large gear to rotate half a circle, and the driven large gear drives the rotating top seat to rotate half a circle synchronously, and the positions of the two electric chucks are switched to transfer the unprocessed workpiece to the processing area, and the processed workpiece is transferred to the loading and unloading area. When the workpiece inside one electric chuck is undergoing CNC processing, the workpiece inside the other electric chuck is loaded and unloaded, thereby effectively improving the CNC processing efficiency of the workpiece.

[0016] In addition, through the sliding cooperation between the eccentric protrusion and the guide slide hole, the driving turntable can drive the limit lock pin to move back and forth along the guide slide hole. When the limit lock pin moves outward, the end of the movable pin head separates from the positioning groove, and the driven large gear is unlocked, so that the positions of the two electric chucks can be rotated and switched. When the limit lock pin moves inward, the end of the movable pin head contacts the outer wall of the driven large gear, and the No. 2 spring is compressed and stored under the influence of the thrust. After the driven large gear is filled with half a circle, the positioning groove and the guide slide hole are precisely connected, and the movable pin head moves inward under the influence of the thrust of the No. 2 spring, so that the end of the movable pin head is inserted into the positioning groove, and the driven large gear is locked and fixed, thereby ensuring the stability of the processing state of the two electric chucks.

[0017] In addition, during the process of the movable pin head end separating from the positioning groove, the driven large gear is not unlocked, the driving small gear stops rotating, the driving turntable rotates alone, and the No. 1 spring is compressed and stored under the influence of the thrust. When the movable pin head end separates from the positioning groove, the driven large gear is unlocked, and the driving small gear rotates and resets under the influence of the thrust of the No. 1 spring. The driving turntable drives the driving small gear to rotate, and the driving small gear further drives the driven large gear to rotate, thereby realizing the rotation switching effect of the two electric chuck positions.

When the workpiece inside one electric chuck 11 is CNC processed, the workpiece inside the other electric chuck 11 is loaded and unloaded, which effectively improves the CNC processing efficiency of the workpiece.

[0035] In this embodiment, the limit lock pin 9 is T-shaped, and the limit lock pin 9 is composed of a main pin handle 91, a movable pin head 92 and a second spring 93. A guide slide hole 801 is provided on the top of the guide bracket 8, and the limit lock pin 9 is slidably connected in the guide slide hole 801. A linkage slide hole 9101 is provided inside the main pin handle 91. An eccentric protrusion 401 is provided on the top of the driving turntable 4, and the eccentric protrusion 401 is slidably connected in the linkage slide hole 9101. The main pin handle 91 is slidably connected with the movable pin head 92. Two square sliders 9102 are symmetrically provided on the outside of the main pin handle 91.

An insert rod 9202 is arranged inside the movable pin head 92, and the end of the insert rod 9202 is slidably inserted in the main pin handle 91. The second spring 93 is sleeved on the outside of the insert rod 9202, and one end of the second spring 93 is in contact with the main pin handle 91, and the other end of the second spring 93 is in contact with the movable pin head 92. Two positioning grooves 701 are symmetrically arranged on the outside of the top of the driven large gear 7, and the end of the movable pin head 92 is slidably inserted in the positioning groove 701;

[0036] By adopting the above technical scheme, the eccentric protrusion 401 slides with the guide slide hole 801, so that the driving turntable 4 can drive the limit lock pin 9 to move back and forth along the guide slide hole 801. When the limit lock pin 9 moves outward, the end of the movable pin head 92 is separated from the positioning groove 701, and the driven large gear 7 is unlocked, so that the positions of the two electric chucks 11 can be rotated and switched. When the limit lock pin 9 moves inward, the end of the movable pin head 92 contacts the outer wall of the driven large gear 7, and the No. 2 spring 93 is compressed and stored under the influence of the thrust. After the driven large gear 7 is filled with half a circle, the positioning groove 701 is accurately connected with the guide slide hole 801, and the movable pin head 92 is moved inward under the influence of the thrust of the No. 2 spring 93, so that the end of the movable pin head 92 is inserted into the positioning groove 701, and the driven large gear 7 is locked and fixed, thereby ensuring the stability of the processing state of the two electric chucks 11.

Two arc movable holes 501 and two through holes 502 are symmetrically arranged inside the driving pinion 5. The arc movable holes 501 are connected to the through holes 502. The fixed blocks 402 are slidably connected in the arc movable holes 501. The arc rod 403 slides through the through holes 502. Two No. 1 springs 6 are sleeved on the outside of the arc rod 403. One end of the No. 1 spring 6 contacts the driving pinion 5, and the other end of the No. 1 spring 6 contacts the fixed block 402.

[0038] By adopting the above technical solution, during the process of separation of the end of the movable pin head 92 from the positioning groove 701, the driven large gear 7 is not unlocked, the driving small gear 5 stops rotating, the driving turntable 4 rotates alone, and the No. 1 spring 6 is compressed and stored under the influence of the thrust. When the end of the movable pin head 92 is separated from the positioning groove 701, the driven large gear 7 is unlocked, and the driving small gear 5 is rotated and reset under the influence of the thrust of the No. 1 spring 6, the driving turntable 4 drives the driving small gear 5 to rotate, and the driving small gear 5 further drives the driven large gear 7 to rotate, thereby realizing the rotation switching effect of the two electric chucks 11 positions.

After the driven large gear 7 is filled with half a circle, the positioning groove 701 is accurately connected with the guide slide hole 801, and the movable pin head 92 is released. The pin head 92 is moved inwardly by the thrust of the No. 2 spring 93, so that the end of the movable pin head 92 is inserted into the positioning groove 701, and the driven large gear 7 is locked and fixed, thereby ensuring the stability of the processing state of the two electric chucks 11; during the separation of the end of the movable pin head 92 from the positioning groove 701, the driven large gear 7 is not unlocked, the active small gear 5 stops rotating, and the driving turntable 4 rotates alone. The No. 1 spring 6 is compressed and stored under the thrust. When the end of the movable pin head 92 is separated from the positioning groove 701, the driven large gear 7 is unlocked, and the active small gear 5 is rotated and reset under the thrust of the No. 1 spring 6, and the driving turntable 4 drives the active small gear 5 to rotate, and the active small gear 5 further drives the driven large gear 7 to rotate, thereby realizing the position rotation switching operation of the two electric chucks 11; when the workpiece inside one of the electric chucks 11 is subjected to CNC machining, the workpiece inside the other electric chuck 11 is loaded and unloaded, and the CNC machining and loading and unloading operations are carried out simultaneously, effectively improving the CNC machining efficiency of the workpiece.
