Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of end face processing devices, in particular to a shaft sleeve end face notch processing device. BACKGROUND

[0002] The shaft sleeve is a cylindrical mechanical part sleeved on a rotating shaft. When it is used as a part of a car, a notch needs to be processed on the end face in the radial direction due to process requirements. However, it is not easy to determine the accurate position of the hole in the radial direction on the end face. Small deviations in part clamping, precision errors of machine tool coordinate axes, and precision of measuring tools may all cause the final processed hole to deviate from the designed radial position, affecting the assembly accuracy of the shaft sleeve and other parts and the overall performance. In addition, the contact mode and stress state of the tool and the shaft sleeve are relatively complex when processing the radial hole, which easily damages the tool and even causes the drill to break.

[0038] 1. Reduce the risk of tool damage:

[0039] When the drill head of the drilling mechanism simultaneously processes the end faces of two bushings that are in close contact, the contact mode and stress state between the tool and the bushing are improved. Compared with processing a single bushing, the end faces of the two bushings are subjected to force at the same time, which disperses the force borne by the tool, making the force on the tool more uniform during the processing and reducing the risk of tool damage or even drill bit breakage due to uneven force.

[0040] 2. Improve the machining accuracy and efficiency of end face notches:

[0041] Because the clamping mechanism can tightly clamp at least two bushings, it provides a certain positioning and constraint function between the bushings, making the bushing position more stable during the machining process. It also helps to improve the radial positional accuracy of the final machined hole on the end face, avoiding the need to ensure the positional accuracy of the notch on different bushings meets the requirements when machining the end faces of different bushings separately, so as to ensure the assembly accuracy of the bushing with other components. Compared with clamping a single bushing, it reduces the impact of small deviations in part clamping on the positional accuracy of the notch to a certain extent. Attached Figure Description

[0064] like Figures 1-3 The diagram illustrates a bushing end face notch processing apparatus according to an embodiment of the present disclosure, used for processing bushing 1. The bushing end face notch processing apparatus includes: a frame 2; a drilling mechanism 3 levitically mounted on the frame 2, the drilling mechanism 3 having a drill head 301; and a clamping mechanism 4 mounted on the frame 2, located below the drilling mechanism 3, for tightly clamping at least two bushings 1. After the drilling mechanism 3 is raised or lowered, the drill head 301 is configured to be close to the end faces of the two bushings 1 that are in contact, so that the drill head 301 simultaneously processes the end faces of the two bushings 1.

[0065] Before processing, the steel structure frame 1 is assembled first, and whether it is stable enough is checked, and a certain washing and blowing cleaning operation is carried out; then clamping operation is carried out, at least two shaft sleeves 1 are placed on the clamping mechanism 4, the shaft sleeves 1 are tightly clamped by the corresponding parts of the clamping mechanism 4, the shaft sleeves 1 are tightly clamped, especially the end faces to be processed are aligned and tightly clamped, which prepares for subsequent synchronous processing; then the drilling mechanism 3 is started, the frame 2 starts to move up and down, gradually approaches the clamped shaft sleeve 1 below, until the drill bit 301 tightly clamps the end face to process the two shaft sleeves 1 synchronously, so as to complete the end face notch processing operation.

[0066] In the above process, it should be noted that when clamping, the end faces of the two tightly clamped shaft sleeves 1 are located directly below the drill bit 301, so that the drill bit can be lowered to smoothly and synchronously process the two tightly clamped end faces. After processing, the drilling mechanism 3 needs to be reset, and the new two tightly clamped end faces need to be adjusted to be directly below the drill bit 301, or a new set of shaft sleeves 1 need to be clamped to ensure the above requirements, so that the processing can continue.

[0067] Specifically, the drilling mechanism 3 can select a motor driven pulley structure to complete the normal operation of the drill bit 301. In addition, the material of the drill bit 301 can be high-speed steel or hard alloy to ensure the high strength and high toughness required for processing and reduce the wear of the cutting tool during processing.

[0068] The clamping mechanism 4 can be clamped by hydraulic pressure or mechanically clamped, such as mechanical clamping. For example, a fixed seat can be arranged on the frame 2 by screw nut cooperation, the screw rod passes through the fixed seat and is connected with the clamping block, and the nut is welded on the other end of the screw rod. Workers rotate the nut by wrench to make the screw rod drive the clamping block close to the fixed seat, so as to tightly clamp a plurality of shaft sleeves 1 between the fixed seat and the clamping block, thereby realizing the clamping of the shaft sleeves 1. In addition, the surface of the clamping block can be provided with anti-skid lines or rubber pads to increase the friction between the shaft sleeves 1 and improve the stability of clamping to avoid rotation of the shaft sleeves 1 during processing. This clamping method has simple structure and low cost, and is suitable for some processing occasions with low clamping precision requirement and small batch.

[0069] Compared with the traditional processing method of processing one by one, on the one hand, it greatly reduces the rapid wear and even breakage of the cutting tool due to the particularity of the processing position; on the other hand, the end clamping of at least two shaft sleeves 1 can ensure the processing precision and the assembly precision of the shaft sleeves 1 and other parts, and can also process the end faces of the two shaft sleeves 1 at the same time, thereby improving the processing efficiency.

[0070] As Figure 2 , Figure 3As shown, in some examples, the clamping mechanism 4 comprises: a column 400 arranged on the rack 2, the column 400 having a limiting surface 401; a support shaft 402 arranged on the limiting surface 401 at one end, the support shaft 402 having a loading end 403 at the other end, the lifting direction extension line of the drill bit 301 penetrating the axial extension line of the support shaft 402, the support shaft 402 being used for supporting the shaft sleeve 1; and a blocking piece 404 detachably arranged on the loading end 403, the limiting surface 401 and the blocking piece 404 forming a clamping area 405 therebetween, the clamping area 405 being used for tightly clamping two shaft sleeves 1.

[0071] The column 400 and the blocking piece 404 detachably arranged on the loading end 403 of the support shaft 402 are used to tightly clamp at least two shaft sleeves 1 from the end, that is, a simple and low-cost mechanical clamping structure is selected; first, the limiting surface 401 of the column 400 provides a stable mounting basis for the support shaft 402, so that the support shaft 402 is conveniently positioned on the rack 2, and the blocking piece 404 is detachably arranged on the suspended loading end 403 of the support shaft 402, so that the shaft sleeve 1 can be conveniently clamped and unclamped in the clamping area 405, that is, when clamping the shaft sleeve 1, the blocking piece 404 is only needed to be removed, the shaft sleeve 1 is sleeved on the support shaft 402, is clamped into the clamping area, and then the blocking piece 404 is clamped, so that the clamping is completed, and the operation is simple and fast.

[0072] Meanwhile, the detachable design is also convenient for replacing the appropriate blocking piece 404 according to the shaft sleeve 1 of different sizes, so that the shaft sleeve 1 is stably clamped in the clamping area 405 through the combined action of the limiting surface 401 and the blocking piece 404, and is limited by the support shaft 402, so that the machining error caused by the displacement of the shaft sleeve 1 in the machining process is effectively reduced, and the universality of the clamping mechanism 4 is enhanced.

[0073] It is worth mentioning that the axial extension line of the support shaft 402 and the lifting direction extension line of the drill bit 301 penetrate, which ensures that the shaft sleeve 1 is sleeved on the support shaft 402 and that the end face to be machined accurately corresponds to the movement track of the drill bit 301 after clamping is completed, so that the drill bit 301 can accurately perform the radial notch machining on the end face of the shaft sleeve 1.

[0074] Specifically, the column 400 is in a columnar structure and is vertically welded on the rack 2, and the limiting surface 401 is in a vertical planar structure and is perpendicular to the horizontal workbench surface of the rack 2; the support shaft 402 is in a cylindrical structure, one end of the support shaft 402 is tightly welded on the limiting surface 401, and the other end of the support shaft 402 is in a suspended loading end 403, the diameter of the support shaft 402 is designed according to the inner diameter of the shaft sleeve 1, so that the shaft sleeve 1 can be smoothly sleeved on the support shaft 402; and the shape of the blocking piece 404 is designed according to the shape of the shaft sleeve 1, and the blocking piece 404 is generally in a circular or square plate structure, and a strip-shaped opening hole (such as a slot) is further formed in the radial direction of the circular plate-shaped blocking piece 404. Figure 3The stopper 404 is slightly larger in diameter than the outer diameter of the shaft sleeve 1, and can be detachably arranged at the loading end 403 through threaded connection, buckle connection, etc. After the stopper 404 is arranged at the loading end 403 and tightly abuts against the shaft sleeve 1, the clamping is completed. For safety, a nut can be further screwed and locked with the support shaft 402 on the side of the stopper 404 away from the shaft sleeve 1, to ensure that the shaft sleeve can be firmly clamped.

[0075] It is worth mentioning that after clamping, the two end faces that need to be tightly abutted are located directly below the drill bit 301. Since the clamping mechanism 4 cannot be moved, a suitable thickness of a pad can be sleeved before the shaft sleeve 1 to ensure that the drill bit 301 can be synchronously machined after being lowered.

[0076] As shown in Figure 3 , Figure 4 In some examples, the shaft sleeve end face notching machining device further comprises: two groups of fixing mechanisms 5 arranged on both sides of the support shaft 402, each group of fixing mechanisms 5 comprising a plurality of fixing mechanisms 5 arranged at intervals along the axial direction of the support shaft 402, each fixing mechanism 5 being slidably arranged on the rack 2, the sliding direction of the fixing mechanism 5 being transverse to the axial direction of the support shaft 402, and the fixing mechanism 5 being configured to abut against the outer wall of the shaft sleeve 1 after sliding.

[0077] The two groups of fixing mechanisms 5 are symmetrically arranged on both sides of the support shaft 402, and each fixing mechanism 5 can abut against the outer wall of the shaft sleeve 1 after sliding. This makes the shaft sleeve 1 in the clamping area 405 not only constrained by the limiting faces 401 and the stopper 404 at both ends, but also limited by the support shaft 402 at the center, and pressed by the fixing mechanisms 5 on the sides, thereby fixing the shaft sleeve 1 from multiple directions to enhance the stability of the clamping of the shaft sleeve 1.

[0078] The fixing mechanisms 5 are arranged at intervals along the axial direction of the support shaft 402. For longer or different diameter shaft sleeves 1, the number of fixing mechanisms 5 can be increased and reasonably distributed to provide more uniform support and constraint, thereby improving the machining adaptability of the machining device.

[0079] The specific fixing mechanism 5 can adopt a pressing plate type, mainly composed of a pressing plate and a screw rod. The pressing plate is in a long strip structure, and is moved to abut against the outer wall of the shaft sleeve 1 along the axial direction of the screw rod by rotating the screw rod, thereby fixing the shaft sleeve 1.

[0080] As shown in Figure 4As shown, in some examples, the fixing mechanism 5 includes: each base 501 is slidably disposed on the frame 2; a position adjustment seat 502 is disposed on the top of the base 501, the position adjustment seat 502 having a strip groove 503, the length direction of the strip groove 503 intersecting the axial direction of the support shaft 402; and a fixing member 504 is slidably disposed in the strip groove 503, the base 501 and / or the fixing member 504 being configured to slide so that the fixing member 504 approaches and abuts against the outer wall of the bushing 1.

[0081] The base 501 can be adjusted in a direction that intersects with the axial direction of the support shaft 402. Furthermore, the fixing member 504 slides in the strip groove 503 of the position adjustment seat 502 at the top of the base 501, and this sliding direction also intersects with the axial direction of the support shaft 402. The position of the fixing member 504 can be further finely adjusted in another dimension that intersects with the axial direction of the support shaft 402, so as to achieve precise control of the contact position of the outer wall of the bushing. This multi-dimensional sliding adjustment method greatly improves the flexibility when fixing the bushing 1 and can better meet the requirements for fixing the bushing 1 in complex processing scenarios.

[0082] When fixing, first install the bushing 1 on the support shaft 402, and use the limiting surface 401 and the stop 404 to initially fix it. Then, slide the base 501 for rough positioning, and finely adjust the fixing part 504 according to the outer diameter of the bushing 1 until it abuts the bushing 1 and is finely adjusted.

[0083] like Figure 4 As shown, in some examples, the fastener 504 includes: a vertical rod 5041 slidably disposed within the strip groove 503; a fixing cylinder 5042 slidably sleeved on the vertical rod 5041, and after the base 501 and / or the vertical rod 5041 slide, the fixing cylinder 5042 is configured to approach and abut against the outer wall of the bushing 1; and a stop 5043 detachably disposed on the vertical rod 5041 for locking the fixing cylinder 5042.

[0084] The base 501 slides and the strip groove 503 are both horizontal plane adjustments, while the vertical rod 5041 slides in the strip groove 503, which can provide the fixed cylinder 5042 with flexible height adjustment in the vertical direction, further adapting to the fixing requirements of different outer diameter bushings. The stop 5043 is mainly used to lock the position of the fixed cylinder 5042 and lock it, improving the fixing flexibility. It can be in the form of a nut, etc.

[0085] The difference from the above fixing process is that, to adjust the position of the fixing part 504, the fixing cylinder 5042 should first be put on the vertical rod 5041, then the specific position of the vertical rod 5041 in the strip groove 503 should be determined until the fixing cylinder 5042 abuts against the outer wall of the bushing 1, and finally the stop 5043 should be locked to complete the fixing.

[0086] Specifically, since the shaft sleeve 1 is in a cylindrical structure, the fixed cylinder 5042 abutting against the outer wall thereof needs to avoid the position of the excess entity part thereon as much as possible after abutting, so as to facilitate the adjustment of the position by the worker and avoid interference with the shaft sleeve 1. Therefore, the fixed cylinder 5042 can be selected as a rotary body structure with a thin upper part and a thick lower part (as shown in Figure 4 In addition, for the processing requirements of some special-shaped shaft sleeves, the outer surface shape of the fixed cylinder can also be designed as a special-shaped structure, such as a partial arc, to ensure close contact with the outer wall of the shaft sleeve.

[0087] As shown in Figure 5 , Figure 6 In some examples, the clamping mechanism 4 includes: two sliding seats 410, each slidingly arranged on the rack 2, the sliding direction of the sliding seat 410 being arranged horizontally, and the extension line of the lifting direction of the drill bit 301 penetrating the extension line of the sliding direction of the sliding seat 410; each sliding seat 410 is rotatably provided with a clamping turntable 411, and the rotation axis of the clamping turntable 411 is arranged horizontally; wherein the two sliding seats 410 are used to slide to drive the two clamping turntables 411 to move close to each other, the two clamping turntables 411 clamping the shaft sleeve 1, and the clamping turntable 411 is used to drive the shaft sleeve 1 to rotate after rotation.

[0088] In addition, a more convenient clamping mechanism 4 is selected, which drives the clamping turntable 411 to move close to each other through the sliding of the two sliding seats 410 on the rack 2, so as to more conveniently clamp the shaft sleeve 1 on the groove or central shaft of the clamping turntable 411, and the shaft sleeve 1 can rotate with the clamping turntable 411 after clamping to adjust the angle of the shaft sleeve 1, so as to adapt to the processing of multiple different angle notches on the end face of the shaft sleeve 1.

[0089] In the specific operation process, first, the two sliding seats 410 are adjusted to appropriate initial positions, so that the distance between the two clamping turntables 411 is greater than the length of at least two shaft sleeves 1 to be clamped, and at the same time, it is ensured that the drilling mechanism 3 is above, then the shaft sleeve 1 is placed between the two clamping turntables 411, clamped in the central groove or sleeved on the central shaft, and the driving device (such as a screw nut mechanism driven by a motor or a cylinder, etc.) of the sliding seat 410 is started to drive the two sliding seats to slide towards each other until the shaft sleeve 1 is clamped between the two clamping turntables 411, and then the drilling mechanism 3 is started to complete the end face processing; specifically, in addition to being able to adjust the angle, the overall position of the two groups of sliding seats 410 relative to the rack 2 can also be adjusted to ensure that the drill rod mechanism 3 processes notches on different end faces after descending.

[0090] As shown in Figures 7-10As shown, in some examples, the chucking turntable 411 has a ring groove 412 on the outer periphery, and the chucking mechanism 4 further comprises: a support seat one 413 arranged on the rack 2 between the two sliding seats 410; two dirt collecting plates 414 respectively arranged on the two sides of the support seat one 413, one end of the dirt collecting plate 414 being connected to the support seat one 413 in sliding mode in the horizontal direction, and the other end of the dirt collecting plate 414 being arranged in the ring groove 412 and being connected to the chucking turntable 411 in sliding mode; wherein the two chucking turntables 411, the two dirt collecting plates 414 and the support seat one 413 form a dirt collecting opening space 415, the dirt collecting opening space 415 being used for supporting the shaft sleeve 1, and the opening of the dirt collecting opening space 415 facing the drill bit 301.

[0091] During the machining process, cutting chips, cooling liquid and other waste will be generated. The traditional machining device cannot solve the problem of waste splashing and pollution. Therefore, the support seat 413 and the two dirt collecting plates 414 are arranged on the chucking mechanism 4, and the dirt collecting opening space 415 is formed together with the chucking turntable 411, and the opening faces the drill bit 301, so that the waste can be directly collected and concentrated for processing after a period of time.

[0092] In order to adapt to the position change of the chucking turntable 411, the two dirt collecting plates 414 are arranged on the two sides of the support seat one 413, one end of the dirt collecting plate 414 extending into the support seat one 413 and being connected by a spring in sliding mode, and the other end of the dirt collecting plate 414 being connected to the ring groove 412 of the chucking turntable 411 in sliding interference mode, so that the dirt collecting opening space 415 can be formed regardless of the position adjustment of the chucking turntable 411, and the components will not be loose.

[0093] Specifically, the chucking turntable 411 is in a disc shape, and the ring groove is arranged on the outer periphery. The other end of the dirt collecting plate 414 can be integrally formed with an arc-shaped protrusion, which is connected to the ring groove 412 in sliding interference mode. In addition, the dirt collecting plate 414 and the support seat one 413 can both be in an arc shape, so as to form a part of the dirt collecting opening space 415 as much as possible to accommodate more waste.

[0094] As shown in the drawings, Figures 7-10 In some examples, the chucking mechanism 4 further comprises: a dirt guide plate 416 arranged at the two ends of the two dirt collecting plates 414, and located at the opening of the dirt collecting opening space 415.

[0095] The dirt guide plate 416 is arranged at the opening of the dirt collecting opening space 415 and at the two ends of the two dirt collecting plates 414, which can effectively guide the cutting chips and cooling liquid generated during the machining process to flow to the dirt collecting space. The dirt guide plate 416 can be an arc-shaped flow guide or a linear flow guide, so as to avoid splashing and improve the dirt collecting efficiency.

[0096] Specifically, the pollution guide plate 416 is generally designed as a long strip or an arc structure to form a continuous pollution guide path, and needs to avoid the position of the support seat 413 with a larger cross-sectional area than the pollution collection plate 414 to avoid interference between the continuous pollution guide plate 416 and the support seat 413. In addition, the pollution guide plate 416 can be integrally formed or welded with the pollution collection plate 414, and the thickness needs to be determined according to the material and stress condition. If a thin material such as a sheet metal is used, the thickness is generally 1-3 mm to ensure the strength and stability of the pollution guide plate during use.

[0097] As shown in Figures 7-10 some examples, the clamping mechanism 4 further includes two connecting plates 417 respectively located at both ends of the support seat 413, and the two ends of each connecting plate 417 are slidingly connected to the adjacent two pollution guide plates 416 for connecting the adjacent two pollution guide plates 416, and the connecting plate 417 has a pollution guide surface 418.

[0098] The connecting plate 417 is provided to connect the two adjacent pollution guide plates 416. The relationship between the pollution collection plate 414 and the support seat 413 is the same, and the missing position is supplemented to cooperate to form a stable pollution collection opening space 415 so that the components will not be loose.

[0099] Specifically, the two ends of the connecting plate 417 extend into the pollution guide plates 414 on both sides and are slidingly connected by springs. The springs are in the pollution guide plates 414, and the two ends of the springs are connected to the pollution guide plates 414 and the connecting plates 417, respectively, to provide a force for the connecting plate 417 to extend out of the pollution guide plate 414. In this way, no matter how the positions of the two clamping rotary discs 411 change, the pollution collection plate 414 and the support seat 413, and the connecting plate 417 and the pollution guide plate 416 can be stably connected and will not be loose. In addition, the connecting plate 417 and the pollution guide plate 416 are adaptively shaped to facilitate early installation. They can both be arc structures, and the arc-shaped pollution guide surface 418 enables the waste to be more quickly collected into the pollution collection opening space 415.

[0100] As shown in Figures 7-10 some examples, the clamping mechanism 4 further includes a support seat 419 provided on one of the pollution collection plates 414 and located in the pollution collection opening space 415. The support seat 419 is used to support the shaft sleeve 1, and the support seat 419 has a set of scale lines 420 configured to be axially parallel to the clamped shaft sleeve 1.

[0101] Especially for a longer or heavier shaft sleeve 1, the support seat 419 can further share part of the weight of the shaft sleeve 1 after being added. In addition, the scale lines 420 provided thereon can facilitate the operator to flexibly adjust the installation position and angle of the shaft sleeve according to the scale lines 420. The premise is that the support seat 419 and the scale lines 420 are both arc structures, and the disconnected position is on one hand to facilitate reading, and on the other hand to avoid the end face machining gap position.

[0102] In particular use, the support seat 419 first supports the shaft sleeve 1, at this time the end face in close contact is just at one side of the scale line 420, after the machining of one notch is completed, the operator can rotate the shaft sleeve 1 again according to the required angle interval, and the machining position of the next notch is determined through the scale line 420, for example, if the angle interval required between adjacent notches is 45°, the shaft sleeve 1 is rotated by 45° after the machining of the first notch is completed, and the next machining starting point is accurately found through the scale line as a reference.

[0103] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than limit the present disclosure. Although the present disclosure is described in detail with reference to the preferred embodiments, it should be understood by those of ordinary skill in the art that the technical solutions of the present disclosure can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present disclosure, and all should be covered in the scope of the claims of the present disclosure.
