Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machine tool automation, and in particular to an automatic system facilitating feeding and discharging operation of a machine tool. BACKGROUND

[0002] The winch comprises a power assembly, a transmission shaft, a speed reduction mechanism, a clutch mechanism and a winding drum. The power assembly is in transmission connection with the transmission shaft. The transmission shaft passes through the winding drum and is in transmission connection with the speed reduction mechanism. The speed reduction mechanism is in transmission connection with the winding drum through the clutch mechanism. The winding drum of the winch needs to be polished on the surface during production to make the surface smooth.

[0003] In the existing machine tool production system of the winch, the polishing of the winding drum needs to be first hoisted to the positioning fixture of the machine tool to complete positioning and fixing, and then the polishing equipment is used to complete the polishing. However, the winding drum will continuously shake during the hoisting and falling to the positioning fixture, so that the drum body cannot be accurately and stably placed on the corresponding position of the positioning fixture, resulting in time-consuming and laborious feeding of the winding drum. In addition, the polished winding drum will also shake greatly during hoisting, which affects the operation safety of the operator. SUMMARY

[0004] To solve the technical problems in the background art, the present application provides an automatic system facilitating feeding and discharging operation of a machine tool.

[0005] The present application adopts the following technical scheme: an automatic system facilitating feeding and discharging operation of a machine tool, which is used for polishing of a winding drum in the production process of a winch. The automatic system comprises:

When the auxiliary guide plates form the positioning space, the second rod and the third rod are in a mutually perpendicular state, and the locking mechanism is used to maintain the perpendicular state between the second rod and the third rod.

[0016] As a further improvement to the above solution, each of the two third rods has a transmission shaft fixedly inserted at one end, which is synchronized with its movement.

DETAILED DESCRIPTION

[0034] In the following, the present application will be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments, without conflict.

[0035] Embodiment 1

[0036] Please combine Figures 1 to 8 , the automated system for facilitating the feeding and discharging operation of the machine tool is used for the polishing operation of the winding drum 100 in the capstan production process, and the automated system comprises a machine tool 1, an inner support device 2, a transfer device, and an auxiliary device 4. The machine tool 1 is a special machine tool used for polishing the surface of the winding drum 100 in the capstan production process.

[0037] The inner supporting device 2 is arranged on the machine tool 1 and used for fixing the winch drum 100 on the machine tool 1 before polishing operation, so as to facilitate subsequent polishing operation of the winch drum 100. The transferring device is suspended above the inner supporting device 2 and used for loading and unloading the winch drum 100 on the inner supporting device 2, facilitating operation. The auxiliary device 4 is arranged on the machine tool 1 and used for assisting positioning of the winch drum 100 on the inner supporting device, so as to facilitate loading of the winch drum 100 to be polished and unloading of the winch drum 100 after polishing.

[0038] In the embodiment, when the winch drum 100 of the capstan needs to be polished on the machine tool, the winch drum 100 to be polished is only needed to be transferred to above the machine tool 1 by the transferring device, and the winch drum 100 is dropped into the machine tool 1 by the auxiliary device, so that the inner supporting device 2 is tightly positioned on the inner supporting device 2, and the winch drum 100 is polished.

[0039] The inner supporting device includes two first supporting plates 21 arranged horizontally, two second supporting plates 22 arranged vertically, and a driving mechanism. Bottoms of the two second supporting plates 22 are fixed to top portions of two proximal ends of the two first supporting plates 21 respectively. The driving mechanism is arranged in the machine tool 1. When the bottom drum opening end surface of the winch drum 100 is arranged on the first supporting plate 21, the driving mechanism is used for guiding the two first supporting plates 21 to move away from each other, so that the two second supporting plates 22 tightly support the inner side wall of the winch drum 100, and the winch drum 100 to be polished is fixed.

[0040] In the embodiment, the two second supporting plates 22 are provided with arc surfaces matched with the inner side wall of the winch drum 100. The cross section formed by the first supporting plate 21 and the second supporting plate 22 is in L-shaped structure. Initially, the two second supporting plates 22 are close to each other. When the winch drum 100 is hung to the position, the winch drum 100 is lowered (the second supporting plate 22 is inserted into the winch drum 100), until the bottom drum opening end portion of the winch drum 100 is supported on the top portions of the two first supporting plates 21. Then, the driving mechanism guides the two first supporting plates 21 to move away from each other, so that the two second supporting plates 22 tightly support the inner side wall of the winch drum 100, and the winch drum 100 to be polished is fixed.

[0041] The driving mechanism includes two limiting blocks 23. The two limiting blocks 23 are arranged in the cavity (not shown) of the machine tool 1 in a sliding manner. The top portions of the two limiting blocks 23 protrude from the top portion of the machine tool 1 and are fixed to the bottoms of the two first supporting plates 21 respectively. In the embodiment, two through grooves (not shown in the figure) are formed in the top portion of the machine tool 1 and communicate with the cavity. The grooves are in rectangular structure and matched with the movement track of the limiting blocks 23. The limiting blocks 23 pass through the through grooves and can move relative to the through grooves, so that the movement of the limiting blocks 23 is synchronized with the movement of the first supporting plates 21.

[0042] The first rod body 24 is rotatably arranged in the cavity, the first rod body 24 penetrates through the two limiting blocks 23 respectively, and the outer periphery of the first rod body 24 is provided with outer threads with opposite screw directions (not shown in the figure). The two limiting blocks 23 are provided with threaded holes (not marked) for the first rod body 24 to penetrate through and matched with the two outer threads with opposite screw directions respectively. The first motor 25 is installed in the machine tool 1, and the output shaft of the first motor 25 is connected to one end of the first rod body 24.

[0043] In the embodiment, the first motor 25 is controlled to rotate, so that the output shaft drives the first rod body 24 to rotate, and the first rod body 24 is matched with the threaded holes in the two limiting blocks 23 through the two outer threads thereon respectively, so that the two limiting blocks 23 move synchronously and reversely in the cavity, thereby driving the first support plate 21 and the second support plate 22 to move synchronously. The first motor 25 can be a speed reducer.

[0044] The moving device includes a hanging frame 3, which is a rectangular frame structure, and each of the four corners of the top surface of the rectangular frame structure has a lifting point 33. In the embodiment, the four lifting points 33 of the hanging frame 3 are connected with lifting ropes, and the free ends of the four lifting ropes are fixed together to be hoisted by a lifting arm of the equipment, so as to realize the lifting and moving of the hanging frame 3.

[0045] The inner sides of the two side arms of the hanging frame 3 are oppositely provided with two power arms 32, and the output ends of the two power arms 32 are both installed with clamping plates 31. The power arm 32 in the embodiment can be a hydraulic cylinder or an electric push rod. The clamping surface of the clamping plate 31 is matched with the outer peripheral side wall of the winding drum 100. By controlling the power arm 32, the two clamping plates 31 can be moved away from or close to each other in the horizontal direction.

[0046] The auxiliary device 4 includes two horizontal second rod bodies 41 and a locking mechanism. The opposite ends of the two second rod bodies 41 are provided with auxiliary guide plates 42 matched with the outer peripheral side wall of the winding drum 100. The opposite sides of the auxiliary guide plates 42 are matched with the outer peripheral side wall of the winding drum 100, and the auxiliary guide plates 42 are always located below the clamping plates 31 to avoid interference with the clamping plates 31.

[0047] The second rod body 41 is rotatably connected with a third rod body 43 at the bottom, and the third rod body 43 is rotatably connected with the machine tool 1 at one end. The second rod body 41 and the third rod body 43 are hingedly connected through a hinge shaft.

[0048] In the embodiment, by driving the end of the third rod body 43 connected with the second rod body 41 to rotate around the rotating connection end with the machine tool 1 towards the winding drum 100, the second rod body 41 is driven to move upward and centripetally, so that a positioning space for stably inserting the winding drum 100 is formed between the two auxiliary guide plates 42, so as to realize the subsequent moving device to be hoisted to the winding drum 100 to be aligned and positioned on the first support plate 21 and the second support plate 22, which is safe and efficient.

[0049] When the auxiliary guide plate 42 forms the positioning space, the second rod body 41 and the third rod body 43 are in a perpendicular state, the locking mechanism is used to maintain the perpendicular state between the second rod body 41 and the third rod body 43, and the positioning space formed by the auxiliary guide plate 42 can be kept stable to stably drop the subsequent winding drum 100.

[0050] Both ends of the two third rod bodies 43 are fixedly inserted with transmission shafts 44 which are synchronous with the movement of the third rod bodies 43, both transmission shafts 44 are located in the machine tool 1, and the second sprocket 492 and the gear 493 are respectively fixed away from one end of the corresponding third rod body 43. Two turntables 45 are arranged in the machine tool 1, and the two turntables 45 are fixed at one end of the two transmission shafts 44 to be synchronous with the rotation of the third rod body 43. The gear 493 is provided with a synchronous shaft (not marked) parallel to the transmission shaft 44, and the second sprocket 492 and the gear 493 are sequentially and fixedly sleeved on the synchronous shaft, and the two gears 493 are meshed with each other to make the two transmission shafts 44 synchronously and reversely rotate. A second motor 49 is installed in the machine tool 1, and a first sprocket 491 is fixed on the output shaft of the second motor 49, and the first sprocket 491 and the two second sprockets 492 are connected through a chain transmission. The second motor 49 can adopt a speed reducer.

[0051] In this embodiment, by controlling the rotation of the second motor 49, the output shaft of the second motor 49 drives the first sprocket 491 to rotate, the first sprocket 491 drives the two second sprockets 492 to synchronously rotate through the corresponding chain, one of the second sprockets 492 drives one of the gears 493 to synchronously rotate through the synchronous shaft, the gear 493 drives the other gear 493 to rotate and the corresponding transmission shaft 44 to synchronously rotate to change the direction, then the two transmission shafts 44 synchronously and reversely rotate to drive the two turntables 45 and the two third rod bodies 43 to synchronously and reversely rotate, so that the two third rod bodies 43 drive the respective second rod bodies 41 and the auxiliary guide plate 42 to move upward and toward the center.

[0052] In order to improve the stability of the perpendicular state between the second rod body 41 and the third rod body 43, at least one fourth rod body 431 is additionally provided between the second rod body 41 and the auxiliary guide plate 42 in this embodiment, the fourth rod body 431 is completely same in structure with the third rod body 43, one end of the fourth rod body 431 is hingedly connected to the bottom wall on the outer circumferential side of the second rod body 41, and the other end is directly hingedly connected to the top of the machine tool 1. The fourth rod body 431 always keeps the state synchronous with the third rod body 43, and the two are always parallel to each other.

[0053] The angle between the rod wall of the third rod body 43 facing the side of the auxiliary guide plate 42 and the second rod body 41 is an acute angle at the beginning, and the angle between the rod wall of the fourth rod body 431 facing the side of the auxiliary guide plate 42 and the second rod body 41 is also an acute angle, and they are parallel to each other. When the positioning space is formed between the auxiliary guide plates 42, the angle between the rod wall of the third rod body 43 facing the side of the auxiliary guide plate 42 and the second rod body 41 is a right angle, and the angle between the rod wall of the fourth rod body 431 facing the side of the auxiliary guide plate 42 and the second rod body 41 is also a right angle, so that the second rod body 41 has one more supporting point relative to the top of the machine tool 1, thereby effectively improving the stability of the device.

[0054] The locking mechanism includes a groove 48 and a positioning block 47. The groove 48 has a downward slot and is arranged on the outer bottom wall of the second rod body 41 away from the side of the auxiliary guide plate 42. An elastic clamping rod 481 is inserted into the bottom of the groove 48. In this embodiment, a moving block (not marked) is installed in the groove 48. The moving block can slide relatively in the groove 48. One end of the clamping rod 481 extends into the groove 48 and is fixedly connected with the block wall of the moving block. The moving block and the groove 48 are connected by a spring (not marked).

[0055] The positioning block 47 is sleeved and fixed on the outer side of the third rod body 43. A clamping hole 471 is formed in the third rod body 43. When the second rod body 41 is perpendicular to the third rod body 43, the clamping rod 481 is clamped and matched with the clamping hole 471. Specifically, when the third rod body 43 gradually changes to a vertical state relative to the second rod body 41, the free end of the clamping rod 481 will be first pressed by the outer wall of the positioning block 47, and part of the clamping rod 481 will be retracted into the groove 48, until the third rod body 43 is completely perpendicular to the second rod body 41. At this time, the free end of the clamping rod 481 is just aligned with the clamping hole 471 of the positioning block 47. The clamping rod 481 is pushed into the clamping hole 471 to realize clamping and fixing under the action of the elastic force.

[0056] In this embodiment, the clamping and fixing between the clamping rod 481 and the clamping hole 471 can make the second rod body 41 and the third rod body 43 always maintain a vertical state, so that the positioning space formed between the auxiliary guide plates 42 remains stable, and the subsequent winch drum 100 can be accurately positioned on the first support plate 21 and the second support plate 22.

[0057] In order to facilitate the release of the vertical state between the second rod body 41 and the third rod body 43, a second electromagnet 483 is installed at the bottom of the clamping hole 471, and a first electromagnet 482 is installed at the free end of the clamping rod 481. When it is necessary to release the vertical state between the second rod body 41 and the third rod body 43, only the first electromagnet 482 and the second electromagnet 483 need to be controlled to be electrified, so that the two magnets repel each other, and the first electromagnet 482 drives the clamping rod 481 to retract into the groove 48, avoiding interference with the rotation of the third rod body 43 relative to the second rod body 41.

[0058] The working mode of the embodiment is as follows: when feeding, the hoisting drum 100 to be polished is first moved to above the machine tool 1 by the moving device, then the positioning space is formed by the two auxiliary guide plates 42 of the auxiliary device, which can reduce the shaking of the hoisting drum 100 when it is hung and lowered, then the hoisting drum 100 is lowered to fall into the positioning space until the second support plate 22 penetrates into the hoisting drum 100 and the bottom drum opening end of the hoisting drum 100 is positioned on the first support plate 21, then the hoisting drum 100 is tightly positioned by the inner support device, the clamping of the hoisting drum 100 by the clamping plate 31 is released, the positioning space formed by the auxiliary guide plates 42 is released, and finally the polishing of the hoisting drum 100 is completed by the polishing equipment.

[0059] When discharging, the positioning space is first formed by the two auxiliary guide plates 42 of the auxiliary device, the tight positioning of the hoisting drum 100 by the inner support device is released, and the hoisting drum 100 is lifted along the height direction of the auxiliary guide plate 42 by the moving device, which can reduce the shaking of the hoisting drum 100 at the initial stage of lifting, facilitate the discharging operation, and improve safety.

[0060] Embodiment 2

[0061] Please refer to Figures 1 to 9 The embodiment is an improved scheme of embodiment 1, specifically, the top of the auxiliary guide plate 42 is provided with a positioning column 46, and the plate body of the clamping plate 31 is provided with a positioning hole 311 matched with the positioning column 46. The positioning column 46 and the positioning hole 311 can further facilitate the accurate positioning of the hoisting drum 100 in the positioning space.

[0062] In the embodiment, the diameter of the positioning hole 311 is much larger than the diameter of the positioning column 46, so as to avoid that when the positioning column 46 is inserted into the positioning hole 311, the clamping plate 31 cannot move a distance due to the interference of the positioning column 46 because the diameter of the positioning hole 311 is small, which interferes with the release of the clamping of the hoisting drum 100.

[0063] In order to enable the positioning column 46 to be matched with the positioning hole 311 with a diameter larger than the diameter of the positioning column 46, a plurality of fifth rod bodies 461 are arranged on the outer side wall of the positioning column 46 along the axial direction at equal intervals.

[0064] Each fifth rod body 461 is installed on the outer circumferential side wall of the positioning column 46 through a reel 462 and a coil spring, that is, when the fifth rod body 461 is not pressed, the fifth rod body 461 forms a certain angle with the positioning column 46 under the action of the coil spring, and for this angle, the embodiment provides that the angle between the outer wall of the positioning column 46 facing the machine tool 1 and the outer side wall of the positioning column 46 below it is an acute angle.

[0065] When the positioning hole 311 falls into the positioning column 46, the wall of the positioning hole 311 will contact and press the free end of the fifth rod body 461, and drive the free end of the fifth rod body 461 to rotate downward by a certain angle around the connection position of the fifth rod body 461 and the positioning column 46, so as to force the coil spring to deform, but the free end of the fifth rod body 461 will always slide and press the wall of the positioning hole 311, so as to provide a stable supporting force for the clamping plate 31 and even the winding drum 100 between the clamping plates 31 through the wall of the positioning hole 311, so that the falling of the winding drum 100 is more stable, and the shaking of the clamping plate 31 and the winding drum 100 is reduced.

[0066] In addition, when the clamping plates 31 are separated from each other, the clamping plate 31 presses the fifth rod body 461 on one side of the positioning column 46 through the inner wall of the positioning hole 311, so that after the clamping plate 31 is separated by a distance, the clamping plate 31 moves upward away from the winding drum 100 after being separated from the outer side wall of the winding drum 100, and the operation is convenient.

[0067] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the protection scope of the present application. Any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the protection scope of the present application.
