Description

Technical Field

[0001] The utility model relates to a loading and unloading device, in particular to a loading and unloading device for a tap and thread grinder, belonging to the technical field of tap and thread grinders. Background Art

[0002] The tap grinder is the core equipment for tap processing, used to grind the threaded part of the tap. The tap grinder is a special tap grinder derived from the external thread grinder, which mainly meets the requirements of high production efficiency and easy operation in tap processing.

[0003] After searching, a Chinese patent with publication number CN220313000U discloses a feeding mechanism for a tap thread grinder, including a telescopic cylinder, a lifting cylinder, a connecting plate, a rotating motor, a pneumatic finger and a transmission unit. The utility model arranges teeth on the chain, and the teeth can well position and clamp the workpiece. The chain is driven by a servo motor, a driving wheel and a driven wheel to the bottom of the pneumatic fingers, and is clamped by multiple pneumatic fingers to a tap relief grinding device for processing. After the processing is completed, it is clamped by the pneumatic fingers to a feeding device. The whole process only requires manual or mechanical arm placement of the tap to be ground on the teeth, and the other processes are fully automated, eliminating the tedious operation of manual loading and unloading, and the cost is low, which can be vigorously promoted.

[0004] Although the above scheme can save the tedious operation of loading and unloading by manpower, and is low-cost and can be widely promoted, the feeding mechanism in the above patent is difficult to control the interval time of feeding. Generally, during the feeding process, due to the excessive feeding flow rate, jamming is prone to occur; for this reason, we provide a tap thread grinder loading and unloading device to solve the above problems.

[0026] See also Figure 3 , including a first single-phase motor 1. The first single-phase motor 1 is a prior art and will not be described in detail. The setting of the first single-phase motor 1 can effectively provide sufficient power for the movement of subsequent components. The output shaft of the first single-phase motor 1 is transmission-connected to one end of the transport crawler 2, and the other end of the transport crawler 2 is transmission-connected to the outer circumferential surface of the first linkage rod 3. The setting of the transport crawler 2 can effectively ensure the synchronous movement of subsequent components, so that their movement efficiency remains consistent.

[0027] See also Figure 1 and Figure 3 The outer circumferential surface of the first linkage rod 3 is fixedly connected with a rubber striking module 4. The setting of the rubber striking module 4 can effectively impact other components. The outer circumferential surface of the first linkage rod 3 is rotatably connected to the bottom of the guide track plate 5. The setting of the guide track plate 5 can effectively make the screw rod slide. The top of the guide track plate 5 is fixedly connected to the bottom of the protective guide plate 8. The setting of the protective guide plate 8 prevents the tap from escaping from the loading and unloading device.

[0028] See also Figure 1 and Figure 4 One end of the protective guide plate 8 is fixedly connected to one side of the component protective shell 11, and the middle part of the component protective shell 11 is slidably connected to the outer circumferential surface of the guide single rod 12. The setting of the guide single rod 12 can effectively ensure the smooth movement of subsequent components. One end of the guide single rod 12 is fixedly connected to one side of the buffer module 13. The setting of the buffer module 13 can preliminarily buffer the rolling inertia brought by the tap itself.

[0029] See also Figure 4One side of the buffer module 13 is fixedly connected to one end of the tough spring 14, and the other end of the tough spring 14 is fixedly connected to one side of the inner wall of the component protective shell 11. The tough spring 14 is sleeved on the outer circumference of the guide single rod 12, and the outer wall of the buffer module 13 is slidably connected to the inner wall of the component protective shell 11.

[0030] See also Figure 1 There are two groups of component protection shells 11. The bottoms of the two groups of component protection shells 11 are fixedly connected to the top of the guide track plate 5. The two groups of component protection shells 11 are symmetrically distributed on both sides of the protection guide plate 8. The purpose of setting multiple groups of component protection shells 11 is to effectively buffer the two ends of the tap to avoid excessive tilting of the tap.

[0031] See also Figure 1 and Figure 2 The bottom of the component protection shell 11 is fixedly connected to the top of the guide track plate 5, and the bottom of the guide track plate 5 is fixedly connected to the top of the component support frame 15. The setting of the component support frame 15 can effectively support other components. The bottom of the inner wall of the component support frame 15 is fixedly connected to the bottom of the second single-phase motor 16. The second single-phase motor 16 is a prior art and will not be described in detail.

[0032] See also Figure 2 The output shaft of the second single-phase motor 16 is rotatably connected to one end of the second linkage rod 17, the other end of the second linkage rod 17 is rotatably connected to one end of the third linkage rod 18, the middle part of the third linkage rod 18 is rotatably connected to one end of the fourth linkage rod 20, the other end of the fourth linkage rod 20 is rotatably connected to one side of the component support frame 15, and the other end of the third linkage rod 18 is rotatably connected to a pusher power rod 19. The mutual cooperation between the second linkage rod 17, the third linkage rod 18 and the fourth linkage rod 20 can effectively make the pusher power rod 19 move back and forth, thereby continuously pushing the tap to move.

[0033] See also Figure 1 The bottom of the guide track plate 5 is fixedly connected with a support vertical plate 21, and the bottom of the support vertical plate 21 is fixedly connected to the top of the support balance base 22. There are two groups of support balance bases 22. Screw holes are set in the middle of the two groups of support balance bases 22. The top of the guide track plate 5 is fixedly connected with a guide protective shell 23. The purpose of setting multiple groups of support balance bases 22 is to effectively ensure that the loading and unloading device always remains stable during operation.

[0034] See also Figure 1 and Figure 3There are two groups of protective guide plates 8, a first blocking plate 9 is fixedly connected between the two groups of protective guide plates 8, a second blocking plate 10 is fixedly connected between the two groups of protective guide plates 8, the bottom of the guide track plate 5 is rotatably connected with a flow control roller 6, the setting of the flow control roller 6 can effectively control the time interval of tap feeding, one end of the flow control roller 6 is fixedly connected to the output shaft of the first single-phase motor 1, and the groove in the middle of the guide track plate 5 is slidably connected with an anti-blocking slider 7, the setting of the anti-blocking slider 7 can prevent the taps from getting stuck due to accumulation.

[0035] Working principle: first, place the tap on the guide track plate 5, on one side of the second blocking plate 10, start the first single-phase motor 1 to work, drive the first linkage rod 3 on the transport crawler 2 to rotate, so that the rubber striking module 4 intermittently hits the anti-blocking slider 7, so that the anti-blocking slider 7 slides in the guide track plate 5 to avoid the accumulation of taps. At the same time, the first single-phase motor 1 will also drive the flow control roller 6 to rotate. Under the action of the shape of the flow control roller 6 itself, the tap enters the groove of the flow control roller 6 and is smoothly placed on the guide track plate 5 through rotation. The tap rolls under the action of its own shape and is blocked and stopped at the designated position. Then start the second single-phase motor 16 to work, drive the third linkage rod 18 on the second linkage rod 17 to rotate, and the third linkage rod 18 uses the intersection with the fourth linkage rod 20 as a fulcrum to start driving the push power rod 19 to move, so that the push power rod 19 pushes the tap to gradually enter the guide protective shell 23 and perform reciprocating motion, thereby effectively controlling the interval time of feeding.
