Description

Technical Field

[0001] The utility model relates to the technical field of a conveying device of an automatic wire dropping machine, in particular to a rotating disk of an automatic wire dropping machine. Background Art

[0002] In the process of automatic assembly of the wire reel, the wire car needs to be clamped and positioned by the automatic wire drop machine turntable. The current automatic wire drop machine turntable is generally composed of a rotating base, a rotating disk, a limit slide rail with a slide groove, and a clamping mechanism. The wire car moves in and out of the rotating disk along the limit slide rail. After entering the rotating disk, the front and rear ends of the wire car are clamped and positioned by the clamping mechanism and the stop block, and then the wire reel is automatically loaded. Due to long-term operation, the positioning and tightening mechanism and the pads at both ends of the wire car will produce certain wear in the process of entering and exiting the wire car, especially the pads, which are generally made of elastic materials. The degree of wear is faster than the clamping part of the clamping mechanism, resulting in a gap between the clamping mechanism and the wire car. When the gap reaches a certain distance, it is easy for the wire car to move backward a certain distance due to the reaction force generated when the front end moves and hits after clamping, which eventually causes the problem of inaccurate positioning of the wire car, making it impossible to accurately install the wire reel on each mounting rod of the wire car, causing the quality tube in the wire reel to break. In severe cases, it will also cause the problem of the wire car flipping over the wire drop machine, resulting in a large number of broken wires. Currently, the solution to this type of problem is basically to replace the clamping blocks on both sides. However, when replacing the clamping blocks, it is basically only replaced when the wire drawing machine has a problem, which can easily affect production and the replacement cost is high. Therefore, it is necessary to improve the existing automatic assembly wire reel to avoid the problem of being unable to accurately position the wire drawing machine after the clamping mechanism is worn. Summary of the invention

[0003] In order to solve certain technical problems existing in the prior art, the purpose of this application is to provide a turntable for an automatic wire dropping machine, which can solve the problem that the automatic assembly wire disc cannot effectively and accurately position the wire car after wear. It has a simple structure, easy control, low improvement cost and good operating stability.

[0004] In order to solve the above existing technical problems, this application adopts the following technical solutions:

[0005] A turntable of an automatic wire dropping machine comprises a rotating base, a rotating disk arranged on the rotating base, two limiting slide rails arranged in parallel on the rotating disk, a pneumatic clamping mechanism arranged on the outer side of the limiting slide rail, and a stop block arranged at one end of the limiting slide rail. After a wire cart moves along the limiting slide rail and enters the rotating disk, it is clamped and positioned by the pneumatic clamping mechanism. The characteristic is that an auxiliary positioning mechanism is also provided on the rotating disk, and the auxiliary positioning mechanism is arranged between the two stop blocks. After entering the rotating disk, one end of the wire cart is relatively clamped and positioned by the auxiliary positioning mechanism and the stop block.

[0006] Preferably, the auxiliary positioning mechanism includes a mounting seat, a rotating device provided on the mounting seat, and a positioning block provided on the rotating device, and the rotating device is suspended on the rotating disk through the mounting seat.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The pneumatic clamping mechanism and the auxiliary positioning mechanism are controlled to position the two ends of the wire cart respectively, wherein the pneumatic clamping mechanism is used to position the end of the wire cart to prevent the wire cart from moving backwards, and the auxiliary positioning mechanism performs secondary positioning on the front end of the wire cart, especially after entering the rotating disk, one end of the wire cart is relatively clamped and positioned through the auxiliary positioning mechanism and the stop block, so that the front end of the wire cart forms a pulling force through the auxiliary positioning mechanism, avoiding the problem of inaccurate positioning of the wire cart due to the retreat of the wire cart due to the existence of a gap, and can effectively solve the problem of inaccurate front and rear positioning of the wire cart on the rotating disk due to material wear of the existing clamping mechanism or pad block, thereby avoiding the occurrence of pipe breakage, wire falling or even wire flipping of the wire cart when the wire cart is installed on the wire disk, making the pneumatic clamping mechanism have a longer service life, a higher fault tolerance rate, a simple structure, easy control, low improvement cost and good operating stability.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] like Figure 1As shown, an automatic wire dropping machine turntable includes a rotating base 3, a rotating disk 4 arranged on the rotating base 3, two limit slide rails 2 arranged in parallel on the rotating disk 4, a pneumatic clamping mechanism 1 arranged on the outside of the limit slide rail 2, and a stop block 5 arranged at one end of the limit slide rail 2. After the wire car moves along the limit slide rail 2 and enters the rotating disk 4, it is clamped and positioned by the pneumatic clamping mechanism 1. An auxiliary positioning mechanism 7 is also provided on the rotating disk 4. The auxiliary positioning mechanism 7 is arranged between the two stop blocks 5. After entering the rotating disk 4, one end of the wire car is relatively clamped and positioned by the auxiliary positioning mechanism 7 and the stop block 5.

[0022] During actual use, the rotating disk 4 is controlled by the rotating base 3 to rotate to the wire car track that needs to be docked. At this time, the pneumatic clamping mechanism 1 and the auxiliary positioning mechanism 7 are in the open state. When the wire car moves along the track and enters the rotating disk 4 for wire loading, the front end of the wire car first enters the open end of the two limit slide rails 2, and the wire car continues to move forward after contacting along the limit slide rails 2 through the pulleys on both sides. When the sensor detects that the end of the wire car enters the rotating disk 4, the pneumatic clamping mechanism 1 and the auxiliary positioning mechanism 7 are controlled to position the two ends of the wire car respectively, among which the pneumatic clamping mechanism 1 is used to position the end of the wire car to prevent the wire car from moving backwards, and the auxiliary positioning mechanism 7 performs secondary positioning on the front end of the wire car, especially the end of the wire car after entering the rotating disk 4 is controlled by the auxiliary positioning mechanism. The positioning mechanism 7 and the stop block 5 are relatively clamped and positioned, so that a pulling force is formed at the front end of the wire car through the auxiliary positioning mechanism 7, so as to avoid the problem of inaccurate positioning caused by the wire car moving backward due to the existence of a gap, and then the wire car is automatically loaded into the wire reel. After the wire reel is installed, the pneumatic clamping mechanism 1 and the auxiliary positioning mechanism 7 are opened again, and the wire car moves backward to exit the rotating disk 4, and the rotating disk 4 waits for the wire reel loading operation of the next wire car. Through the improvement of the auxiliary positioning mechanism 7, the problem of inaccurate front and rear positioning of the wire car on the rotating disk 4 due to material wear of the existing clamping mechanism or pad can be effectively solved, thereby avoiding the occurrence of pipe breakage, wire falling or even wire turning of the wire car when loading the wire reel, so that the pneumatic clamping mechanism 1 has a longer service life and a higher fault tolerance rate.

[0023] Further improvement is as follows: Figure 2 As shown, the auxiliary positioning mechanism 7 includes a mounting seat 71, a rotating device 76 arranged on the mounting seat 71, and a positioning block 75 arranged on the rotating device 76. The rotating device 76 is suspended on the rotating disk 4 through the mounting seat 71.

[0024] The cam 75 is in a state of being lifted up when the lever 72 is in a state of being moved, and the ...

[0025] A further improvement is that the rotating device 76 is a rotary clamping cylinder, one end of the positioning block 75 is fixed on the rotating shaft of the rotary clamping cylinder, and the positioning block 75 is controlled to rotate 0° and 90-180° through the rotary clamping cylinder.

[0026] Among them, the rotating device 76 adopts a rotary clamping cylinder structure, which has a simpler structure and is more convenient to control when it is linked with the pneumatic clamping mechanism 1. The positioning accuracy of the positioning block 75 is higher and it is not easy to be misplaced. When controlling the positioning block 75, the rotation angle of the rotary clamping cylinder is generally 90°, that is, when the positioning block 75 is 0°, the positioning block 75 is in a downward vertical device, which can form a positioning effect on the wire car. When the positioning block 75 is rotated 90° by the rotary clamping cylinder, it can be completely separated from the wire car, thereby facilitating the withdrawal of the wire car.

[0027] As a further improvement, a speed regulating valve 72 is provided between the rotary clamping cylinder and the positioning block 75; a positioning hole 73 is also provided on the positioning block 75, and an adjusting screw 74 is provided on the positioning hole 73, and the contact end of the adjusting screw 74 faces the rotary clamping cylinder.

[0028] When the positioning block 75 is rotated, it is controlled by the speed regulating valve 72, so that the rotation speed and angle control of the positioning block 75 can be more convenient and rapid. At the same time, an adjusting screw 74 is installed on the positioning block 75 through the positioning hole 73, which can make the auxiliary positioning mechanism 7 more convenient to adjust the precision when positioning the wire machine, and it is more convenient to replace the contact end, so that its use range is wider.

[0029] As a further improvement, a rubber column 6 fixed by bolts is provided on the inner side of the stop block 5 .

[0030] When the stop block 5 contacts the movable base of the wire drawing machine, it is buffered by the rubber column 6, which can avoid the problem of excessive impact force when the wire drawing machine stops and causing deformation of the stop block 5. The rubber column 6 is fixed to the inner side of the stop block 5 by bolts, which is more convenient for replacement.

[0031] Further improvement is as follows: Figure 3 The pneumatic clamping mechanism 1 includes a control cylinder 12 arranged on the rotating disk 4, a clamping block 11 installed on the rotating disk 4 through a rotating shaft, and a solenoid valve 8 for controlling the air supply pipeline of the control cylinder 12. The piston rod of the control cylinder 12 is rotatably connected to one end of the clamping block 11. The clamping block 11 is driven to rotate by the control cylinder 12, and the end of the wire machine entering the limiting slide rail 2 is positioned by the clamping block 11. The air supply pipelines of the two control cylinders 12 and the rotary clamping cylinder are synchronously controlled by the solenoid valve 8.

[0032] The clamping block 11 is installed on the rotating disk 4 through a rotating shaft, and the two ends of the control cylinder 12 are respectively rotatably connected to the rotating disk 4 and one end of the clamping block 11. When the piston rod of the control cylinder 12 is in telescopic control, it can drive the clamping block 11 to rotate along the rotating shaft, so that the other end of the clamping block 11 can produce a positioning, clamping and loosening effect on the wire car through rotation. Among them, the clamping end of the clamping block 11 is formed with a bending portion. When the clamping block 11 is in tightening, the bending portion rotates to the outer side of the end of the wire car for contact, and the air supply pipelines of the two control cylinders 12 and the rotary clamping cylinder are synchronously controlled by the solenoid valve 8, which is more convenient when positioning and loosening the wire car, and the linkage effect is better, which can enable the three cylinders to achieve the effect of synchronous control.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
