Description

Technical Field

[0001] The invention relates to the technical field of drilling machine processing, and in particular to a radial drill structure for processing a bucket hole of a scraper. Background Art

[0002] During the manufacturing process of the bucket of the scraper loader, it is necessary to drill holes at specific locations for connection with various components. Due to the large size of the bucket, a large radial drill is generally used for drilling.

[0003] After searching, the Chinese patent document with the publication number of CN115722697B discloses a rocker drill structure for processing bucket holes of a shovel loader, including a base, a lifting column on the base, a rocker arm on the lifting column, a spindle box on the rocker arm, a spindle drill at the bottom of the spindle box, an intelligent program for controlling the movement and drilling of the rocker arm, the spindle box, and the spindle drill, and a total circuit for transmitting current. The base is provided with a hydraulic transmission device, and a symmetrical clamping seat is slidably connected to the base. The patent compresses the gas in the airbag into the active cavity through the force compression of the airbag, so that the pressed gas pushes the contact I to move in the direction of the contact II. When there is a part of the clamping rod that cannot contact the workpiece, so that the top rod cannot drive the contact II to move in the direction of the contact I, resulting in the inability to connect the series circuit, the contact I can contact with the contact II under the push of the gas, ensuring the connection of the series circuit, so that the electrorheological fluid can be converted into a solid state, so that the clamping rods on both sides clamp the irregular workpiece.

[0004] However, the above invention has the following shortcomings: the electrorheological fluid is used to move the clamping rod in a solidified form. First, the cost of the electrorheological fluid is relatively high, which increases the maintenance cost of the entire clamping mechanism; second, the hardness of the electrorheological fluid after solidification may not be sufficient, because the solidification hardness of the electrorheological fluid is positively correlated with the applied voltage. In order to obtain high strength, a high-voltage power supply is often required, which undoubtedly reduces the safety of the working environment; third, the problem of sealed storage needs to be considered.

DETAILED DESCRIPTION

[0029] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, an embodiment of the present invention provides a radial drill structure for processing a bucket hole of a shovel loader, comprising a workbench 1 and a clamping assembly 6 arranged on the workbench 1, wherein the clamping assembly 6 comprises a bracket 7 and two contact structures 9, the bracket 7 is fixed on the workbench 1, and the two contact structures 9 are symmetrically arranged on the top of the bracket 7;

[0031] Among them, the contact structure 9 includes a movable shell 12, and a centering component 8 is arranged on the bracket 7 to enable the two movable shells 12 to perform centering movement. A plurality of sliding holes are opened on the opposite sides of the two movable shells 12, and clamping rods 14 are slidably arranged in all the sliding holes, and a first reset structure that enables the clamping rod 14 to be reset is arranged in the movable shell 12, and a plurality of cylinders 46 are arranged in the movable shell 12 coaxially with the clamping rod 14, and two semi-internal threaded cylinders 32 that can form a complete internal threaded cylinder are arranged in the cylinder 46, and a threaded section 27 meshing with the internal threaded cylinder is opened on the outer side of the clamping rod 14, and a second reset structure is arranged between the semi-internal threaded cylinder 32 and the cylinder 46, and a driving component that enables the two semi-internal threaded cylinders 32 to mesh and rotate the meshed semi-internal threaded cylinder 32 is arranged inside the movable shell 12.

[0032] In the present invention, the workpiece to be processed is placed between two contact structures 9, and the centering component 8 causes the movable shells 12 of the two contact structures 9 to perform centering movement. The clamping rods 14 on the movable shells 12 contact the workpiece to be processed, and the clamping rods 14 move toward the inside of the movable shell 12. When the movable shell 12 no longer moves, the driving component causes the two semi-internal threaded tubes 32 on the outside of each clamping rod 14 to engage. If the two semi-internal threaded tubes 32 are not engaged, it proves that the threaded ends of the two semi-internal threaded tubes 32 are not inserted into the threads of the threaded ends of the clamping rod 14. The driving component causes the two semi-internal threaded tubes 32 to rotate around the central axis of the clamping rod 14 until the threaded ends of the two semi-internal threaded tubes 32 are inserted into the threads of the threaded ends of the clamping rod 14. The entire clamping component 6 adopts a mechanical structure with a simple structure, which makes the maintenance cost low.

[0033] To supplement the above, the semi-inner threaded barrel 32 and the clamp rod 14 are threadedly engaged so that the semi-inner threaded barrel 32 has a rotation tendency, and the semi-inner threaded barrel 32 applies an outward thrust to the clamp rod 14 through the thread.

[0034] Specifically, a rotating table is installed on the table top of the workbench 1, a longitudinal linear module 2 is installed on the rotating end of the rotating table, a transverse moving module 3 is installed on the moving end of the longitudinal linear module 2, a telescopic module 4 is installed on the moving end of the transverse moving module 3, and a drilling rig 5 is installed on the telescopic end of the telescopic module 4.

[0035] To supplement the above, the rotary table, the longitudinal linear module 2, the lateral moving module 3, the telescopic module 4 and the drilling rig 5 are all prior arts, and their specific structures and working principles are not elaborated in detail here.

[0036] Specifically, the first reset structure includes an intermediate plate 16, multiple first springs 15 and multiple limit rings 13. The intermediate plate 16 is fixed in the movable shell 12. The clamping rod 14 is slidably inserted on the intermediate plate 16. The multiple limit rings 13 are coaxially fixed with the multiple clamping rods 14, respectively. The multiple first springs 15 are respectively mounted on the multiple clamping rods 14, and the two ends of the first spring 15 are respectively in contact with the limit ring 13 and the intermediate plate 16.

[0037] In the present invention, when the clamp rod 14 contacts the processed part, the clamp rod 14 moves into the movable shell 12 , the clamp rod 14 drives the limit ring 13 to move synchronously, and the limit ring 13 compresses the first spring 15 .

[0038] Specifically, the second reset structure includes a set of double-section telescopic cylinders 35 , both ends of which are fixed on the cylinder 46 and the semi-internal threaded cylinder 32 , respectively, and a fourth spring 34 is sleeved on the outer side of the double-section telescopic cylinder 35 .

[0039] In the present invention, when no external force is applied, the fourth spring 34 is in a compressed state, and the fourth spring 34 applies a force to the semi-inner threaded cylinder 32 , so that the semi-inner threaded cylinder 32 has a tendency to move toward the clamping rod 14 .

[0040] Specifically, the driving assembly includes multiple slide cylinders 23, and the outer side of the movable shell 12 is provided with multiple circular holes respectively aligned with the multiple clamping rods 14. The multiple slide cylinders 23 are respectively slidably arranged in each circular hole, and a conical ring 21 coaxially arranged therewith is fixed to one end of the slide cylinder 23 facing the clamping rod 14, and a second spring 22 is sleeved on the outer side of the slide cylinder 23, and the two ends of the second spring 22 are respectively in contact with the movable shell 12 and the conical ring 21, an extension rod 20 is fixed to one end of the semi-inner threaded cylinder 32, and a pulley 33 is rotatably installed on one end of the extension rod 20, and each slide cylinder 23 is commonly fixed with a connecting plate 24.

[0041] In the present invention, in the absence of external force, the second spring 22 is in a compressed state. When the second spring 22 applies force to the conical ring 21 on the cylinder 46 , the conical ring 21 has a tendency to move toward the two semi-inner threaded cylinders 32 .

[0042] Specifically, the driving assembly also includes a rotating rod 17. Through holes are provided on both sides of the moving shell 12. The two ends of the rotating rod 17 are rotatably installed in the two through holes respectively. A worm gear 18 coaxially arranged therewith is fixed to the outer side of the cylinder 46. One end of the cylinder 46 is rotatably installed on the middle plate 16. A plurality of worms 19 respectively meshing with the plurality of worm gears 18 are movably sleeved on the outer side of the rotating rod 17. Support plates 31 are rotatably installed at both ends of the worm 19. The support plates 31 are fixed in the moving shell 12. A plurality of fixing rings 28 are fixed to the outer side of the rotating rod 17. A plurality of third springs 29 are sleeved on the outer side of the rotating rod 17, and one ends of the plurality of third springs 29 are respectively in contact with a plurality of fixed rings 28. A plurality of friction discs 30 are movably sleeved on the outer side of the rotating rod 17, and the other ends of the plurality of third springs 29 are respectively in contact with a plurality of friction discs 30, and each friction disc 30 is respectively in contact with a plurality of worm gears 19 by means of the elastic force of the third springs 29 in contact with it. A first gear 25 coaxially arranged therewith is fixed to one end of the rotating rod 17, and a tooth plate 26 meshing with the first gear 25 is fixed to the outer side of the connecting plate 24.

[0043] In the present invention, when the rotating rod 17 rotates, each friction disc 30 on the rotating rod 17 contacts with multiple worms 19 respectively by means of the elastic force of the third spring 29 in contact with it. The friction disc 30 causes the worm 19 to rotate through the friction force, and the worm 19 causes the worm wheel 18 meshing with it to rotate. The worm wheel 18 drives the cylinder 46 to rotate until the semi-internal threaded cylinder 32 on the cylinder 46 meshes with the clamping rod 14.

[0044] Specifically, the centering assembly 8 includes an electric push rod 36, a first push plate 39 and two first connecting rods 43. Two slide grooves 10 are provided on the top of the bracket 7, and a group of guide rods are fixed in the two slide grooves 10, and a movable plate 11 is slidably sleeved on each group of guide rods. One end of the electric push rod 36 is fixed on the bracket 7, one end of the two first connecting rods 43 is rotatably mounted on the two ends of the first push plate 39, and the other ends of the two first connecting rods 43 are rotatably mounted on the two movable plates 11, and the two movable shells 12 are respectively fixed to the two movable plates 11. A second push plate 42 is provided on the top of the first push plate 39, and a plurality of guide rods are fixed on the outer side of the first push plate 39. The guide column 47 and the outer sides of the multiple guide columns 47 are all slidably sleeved with a slide plate 41, which is fixed to the second push plate 42. The second connecting rods 45 are rotatably installed at both ends of the second push plate 42, and one end of the second connecting rod 45 is rotatably installed with a double-section telescopic column 44. One end of the double-section telescopic column 44 on the two second connecting rods 45 is respectively fixed on the two connecting plates 24. A recess is provided on the top of the first push plate 39, and a second gear 38 is rotatably installed in the recess. The telescopic end of the electric push rod 36 is fixed with a first rack 37, and the bottom of the second push plate 42 is fixed with a second rack 40. The first rack 37 and the second rack 40 are both meshed with the second gear 38.

[0045] To supplement the above description, the elastic coefficient of the first spring 15 is much smaller than the elastic coefficient of the second spring 22 .

[0046] In the present invention, since the second spring 22 supports the conical ring 21, the connecting plate 24 fixed to the slide cylinder 23 is closely fitted to the moving shell 12, and the elastic coefficient of the first spring 15 is much smaller than the elastic coefficient of the second spring 22, when the electric push rod 36 is extended, the first rack 37 on the telescopic end of the electric push rod 36 will not move the second gear 38 in the recess, and the second gear 38 pushes the first push plate 39, and the first push plate 39 pulls the two moving shells 12 closer to each other through the two first connecting rods 43 until the moving plate 11 of the moving shell 12 contacts one end of the slide groove 10, at this time, the electric push rod 36 is extended. The telescopic end of the push rod 36 continues to extend, and the first rack 37 on the telescopic end shifts the second gear 38. The second gear 38 moves the second push plate 42 toward the bracket 7 through the second rack 40. The second push plate 42 causes the two connecting plates 24 to move synchronously and away from each other through the second connecting rod 45. The connecting plate 24 pulls the conical ring 21 away from the semi-internal threaded tube 32 through the sliding tube 23. The fourth spring 34 extends to make the semi-internal threaded tube 32 fit the threaded end of the clamping rod 14. When the toothed plate 26 on the connecting plate 24 shifts the first gear 25, the first gear 25 drives the rotating rod 17 to rotate.

[0047] Working principle: the part to be processed is placed between the two contact structures 9. Since the second spring 22 supports the conical ring 21, the connecting plate 24 fixed to the cylinder 46 of the conical ring 21 is tightly fitted to the movable shell 12, and the elastic coefficient of the first spring 15 is much smaller than the elastic coefficient of the second spring 22. When the electric push rod 36 is extended, the first rack 37 on the telescopic end of the electric push rod 36 will not move the second gear 38 in the recess, and the second gear 38 pushes the first push plate 39. The first push plate 39 pulls the two movable shells 12 closer to each other through the two first connecting rods 43. Each clamping rod 14 on the movable shell 12 contacts the part to be processed, and the clamping rod 14 moves toward the inside of the movable shell 12. The clamping rod 14 drives the limit ring 13 to move synchronously, and the limit ring 13 compresses the first spring 15 until the movable shell 12 The movable plate 11 contacts one end of the slide groove 10, and the movable shell 12 stops moving. At this time, the telescopic end of the electric push rod 36 continues to extend, and the first rack 37 on the telescopic end drives the second gear 38. The second gear 38 causes the second push plate 42 to move toward the bracket 7 through the second rack 40. The second push plate 42 causes the two connecting plates 24 to move synchronously and away from each other through the second connecting rod 45. The connecting plate 24 pulls the conical ring 21 away from the semi-inner threaded cylinder 32 through the cylinder 46. The fourth spring 34 extends to make the semi-inner threaded cylinder 32 fit the threaded end of the clamping rod 14. When the toothed plate 26 on the connecting plate 24 drives the first gear 25, the first gear 25 drives the rotating rod 17 to rotate until the threaded ends of the two semi-inner threaded cylinders 32 are stuck in the threads of the threaded ends of the clamping rod 14, thereby limiting the clamping rod 14.

[0048] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
