Description

Technical Field

[0001] This utility model belongs to the technical field of automated processing equipment and relates to a transmission mechanism for continuous processing of precision devices. Background Technology

[0002] Currently, the processing of precision components involves first cutting long rods into standard lengths of workpieces, and then placing these standard length workpieces into the processing equipment for processing. The loading of workpieces requires manual labor, which is inefficient.

[0003] For example, a Chinese patent discloses a CNC machining lathe [application number: 201810497644.4], which includes a clamping component including a three-jaw chuck on both sides of the worktable and an auxiliary clamping part. The auxiliary clamping part includes a base slidably connected to the machine body and a sleeve on the base for holding the workpiece. A push rod is slidably connected inside the sleeve, and several auxiliary jaws are hinged to the outside of the sleeve. A linkage is provided between the auxiliary jaws and the push rod. When the workpiece abuts against the push rod, the linkage drives the auxiliary jaws to rotate toward the workpiece to clamp the workpiece, which can clamp the parts more firmly. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a transmission mechanism for continuous processing of precision devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A transmission mechanism for continuous processing of precision components includes a base, a rotating clamp with a transmission channel inside the base, a continuous transmission mechanism for transmitting rods into the transmission channel on the side of the base, a storage rack fixed on the base, a closable transmission component corresponding to the rotating clamp on one side of the top of the storage rack, and a continuous feeding component for feeding rods into the closable transmission component on the storage rack.

[0007] In the aforementioned transmission mechanism for continuous processing of precision devices, the encloseable transmission component includes a transmission pipe having an axial conveying channel corresponding to the transmission channel. The inner side of the transmission pipe is provided with an opening that has an arc-shaped cross-section and can be connected to the top of the storage rack. The transmission pipe is also provided with a plurality of opening sealing components along the axial direction, and an axial transmission component is provided at the bottom of the transmission pipe.

[0008] In the aforementioned transmission mechanism for continuous processing of precision devices, the opening sealing assembly includes an arc-shaped groove arranged circumferentially along the transmission tube, the arc-shaped groove being connected to the opening, an arc-shaped stop bar being provided inside the arc-shaped groove, and an arc-shaped toothed portion being provided on the outer circumferential surface of the arc-shaped stop bar.

[0009] In the aforementioned transmission mechanism for continuous processing of precision devices, the opening sealing assembly further includes a gearbox fixed on the transmission pipe. The connection between the gearbox and the transmission pipe has a connecting groove that connects to the arc-shaped groove. The gearbox is equipped with a drive gear driven by a No. 1 motor, and the drive gear meshes with the arc-shaped teeth on the arc-shaped stop bar.

[0010] In the aforementioned transmission mechanism for continuous processing of precision components, the axial transmission component includes a conveyor belt mounting groove located at the bottom of the transmission tube, a conveyor belt driven by several pulleys is installed in the conveyor belt mounting groove, and a second motor connected to the pulleys is fixedly connected to the storage rack.

[0011] In the aforementioned transmission mechanism for continuous processing of precision devices, the outer circumferential surface of the pulley is recessed inward and the cross-section is arc-shaped.

[0012] In the aforementioned transmission mechanism for continuous processing of precision components, the continuous feeding assembly includes two horizontal slide rails perpendicular to the transmission tube. A lower pusher plate is provided on the upper side of the horizontal slide rails. A pusher plate translation assembly is provided on the horizontal slide rails to drive the lower pusher plate to move closer to or away from the transmission tube. An upper pusher plate is provided on the upper side of the lower pusher plate. A pusher plate lifting cylinder is fixedly connected to the bottom of the lower pusher plate to drive the upper pusher plate to rise and fall vertically. A vertical pusher plate is fixedly connected to the top of the upper pusher plate.

[0013] In the aforementioned transmission mechanism for continuous processing of precision components, the pusher plate translation assembly includes a pusher plate drive threaded rod disposed in a horizontal slide rail seat. A pusher plate drive slider with its top connected to the lower pusher plate is screwed onto the pusher plate drive threaded rod. A No. 3 motor connected to the pusher plate drive threaded rod is also fixedly connected to one end of the horizontal slide rail seat.

[0014] In the aforementioned transmission mechanism for continuous processing of precision components, a number of vertically extending limiting rods are fixedly connected to the bottom of the upper pusher plate and penetrate the lower pusher plate.

[0015] In the aforementioned transmission mechanism for continuous processing of precision devices, the top of the vertical pusher plate has an arc-shaped portion.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. The continuous transmission mechanism can transport long strips of rods that have not been cut into standard lengths to the rotary clamp. During processing, rotating the rotary clamp can drive the long strip of rod to rotate as a whole. In conjunction with the component processing mechanism, the cutting and drilling of the front end of the rod can be realized. After processing, the processed component is cut off. There is no need to repeatedly load and unload. The long strip of rod can be transported to the enclosed transmission component through the continuous feeding component, and then transported to the rotary clamp through the enclosed transmission component. The enclosed transmission component can also limit the long strip of rod when it rotates.

[0018] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0020] Figure 2 This is a cross-sectional view of a continuous transmission mechanism. Detailed Implementation

[0021] like Figure 1 and Figure 2 As shown, a transmission mechanism for continuous processing of precision components includes a base 1, a rotating clamp 3 with a transmission channel inside the base 1, a continuous transmission mechanism 4 for transmitting rods into the transmission channel on the side of the base 1, a storage rack 5 fixed on the base 1, a closable transmission component 6 corresponding to the rotating clamp 3 on one side of the top of the storage rack 5, and a continuous feeding component 7 for feeding rods into the closable transmission component 6 on the storage rack 5.

[0022] In this invention, a continuous transmission mechanism can transport long strip-shaped rods that have not been cut into standard lengths to be processed to a rotating clamp. During processing, rotating the rotating clamp can drive the long strip-shaped rods to rotate as a whole. In conjunction with the component processing mechanism, cutting and drilling can be performed on the front end of the rods. After processing, the processed components are cut off. There is no need for repeated loading and unloading. The long strip-shaped rods can be transported to the enclosed transmission component 6 through the continuous feeding component 7, and then transported to the rotating clamp through the enclosed transmission component 6. The enclosed transmission component 6 can also limit the long strip-shaped rods when they rotate.

[0023] Specifically, the encloseable transmission assembly 6 includes a transmission pipe 9 with an axial conveying channel 8 corresponding to the transmission channel. The inner side of the transmission pipe 9 has an arc-shaped opening 10 that connects to the top of the storage rack 5. Several opening sealing assemblies 11 are also arranged axially on the transmission pipe 9, and an axial transmission assembly 12 is provided at the bottom of the transmission pipe 9. The elongated rod at the top of the storage rack 14 can enter the axial conveying channel 15 through the opening. After the elongated rod enters the axial conveying channel 15, the opening sealing assemblies can seal the opening. The axial transmission assembly at the bottom of the transmission pipe 16 can transport the elongated rod in the axial conveying channel 15 into the rotating clamp to achieve continuous processing of standard-length components.

[0024] Specifically, the opening sealing assembly 11 includes an arc-shaped groove 13 arranged circumferentially along the transmission pipe 9, which communicates with the opening 10. An arc-shaped stop bar 14 is disposed within the arc-shaped groove 13, and arc-shaped teeth are provided on the outer circumferential surface of the arc-shaped stop bar 14. The opening sealing assembly 11 also includes a gearbox 15 fixed to the transmission pipe 9. The connection between the gearbox 15 and the transmission pipe 9 has a connecting groove 16 communicating with the arc-shaped groove 13. A drive gear 18 driven by a primary motor 17 is disposed within the gearbox 15, and the drive gear 18 meshes with the arc-shaped teeth on the arc-shaped stop bar 14. The primary motor 22 can drive the drive gear to rotate, and the drive gear can drive the arc-shaped stop bar 19 to slide within the arc-shaped groove through the arc-shaped teeth.

[0025] Specifically, the axial transmission assembly 12 includes a conveyor belt mounting groove 19 located at the bottom of the transmission pipe 9. A conveyor belt 21, driven by several pulleys 20, is installed within the conveyor belt mounting groove 19. A second motor 22, connected to the pulleys 20, is fixedly connected to the storage rack 5. The second motor 27 drives the pulleys to rotate, which in turn drives the conveyor belt to rotate, thereby conveying the elongated rods within the axial transmission channel 15 into the transmission channel.

[0026] Specifically, the outer circumferential surface of the pulley 20 is recessed inward and has an arc-shaped cross-section.

[0027] The continuous feeding assembly 7 includes two horizontal slide rail seats 23 perpendicular to the transmission pipe 9. A lower pusher plate 24 is provided on the upper side of the horizontal slide rail seat 23. A pusher plate translation assembly is provided on the horizontal slide rail seat 23 to drive the lower pusher plate 24 to move closer to or away from the transmission pipe 9. An upper pusher plate 25 is provided on the upper side of the lower pusher plate 24. A pusher plate lifting cylinder 26 is fixedly connected to the bottom of the lower pusher plate 24 to drive the upper pusher plate 25 to rise and fall vertically. A vertical pusher plate 27 is fixedly connected to the top of the upper pusher plate 25. During feeding, the pusher plate lifting cylinder 31 can drive the upper pusher plate 30 to rise, moving the vertical pusher plate above the storage rack. Then, the pusher plate translation assembly drives the lower pusher plate 29 to move closer to the transmission pipe 16, pushing the long strip into the axial conveying channel 15.

[0028] Specifically, the pusher plate translation assembly includes a pusher plate drive threaded rod 28 disposed within a horizontal slide rail seat 23. A pusher plate drive slider, whose top is connected to the lower pusher plate 24, is screwed onto the pusher plate drive threaded rod 28. A third motor 29, connected to the pusher plate drive threaded rod 28, is also fixedly connected to one end of the horizontal slide rail seat 23. The operation of the third motor can drive the pusher plate drive threaded rod 34 to rotate. The rotation of the pusher plate drive threaded rod 34 can drive the pusher plate drive slider to move closer to or away from the transmission pipe 16. The movement of the pusher plate drive slider closer to or away from the transmission pipe 16 can drive the lower pusher plate 29 to move closer to or away from the transmission pipe 16.

[0029] Preferably, a plurality of vertically extending limiting rods 30 are fixedly connected to the bottom of the upper push plate 25, penetrating the lower push plate 24. The limiting rods can limit the movement of the upper push plate.

[0030] Specifically, the top of the vertical push plate 27 has an arc-shaped part 31.
