Description

Technical Field

[0001] The utility model relates to the technical field of workpiece grinding treatment, in particular to a burr grinding device for shaft parts. Background Technique

[0002] In the processing of shaft parts, it is often necessary to complete the cutting of the circumferential surface through turning process, as well as the cutting of the end face and the end process chamfer. When turning the end face of the shaft part, especially when turning the formed chamfer, burrs are likely to be generated at positions such as the edge of the end face and the edge of the shaft shoulder. The existence of burrs not only affects the quality of the parts, but if not removed in time, during the assembly and relative rotation of the shaft parts with other hole parts, it may also affect the performance, reliability, safety and service life of the subsequent products. Therefore, it is very necessary to remove the burrs at the chamfered parts.

[0003] Currently, most of the burrs at the chamfered parts of shaft parts are removed by manual grinding. Most use sandpaper to slowly grind off the burrs at the chamfered parts. However, this grinding method has a large manual labor intensity, low removal efficiency and cannot ensure that each workpiece can have its burrs removed completely. There have also appeared many special or general burr grinding devices on the market, such as an R-angle burr grinding device disclosed in the publication number CN116765973A, a burr grinding device disclosed in the publication number CN109129079A, a grinding and deburring machine disclosed in the publication number CN117124167A, a hub burr grinding device disclosed in the publication number CN112571194A, a burr grinding device disclosed in the publication number CN107009216A, etc., which can all realize the electrified removal operation of the burrs of the corresponding workpieces. However, when these devices are performing grinding operations, at the clamping station, only one workpiece can be clamped at a time, and the grinding mechanism also grinds the workpiece individually. After the grinding operation is completed, it is necessary to temporarily stop the grinding mechanism, unload the ground workpiece from the clamping station, and then clamp the new workpiece to be ground, and then repeat the grinding operation. The grinding of each workpiece completely traverses all links such as clamping, grinding, stopping, and blanking, reducing the production efficiency. Content of the Utility Model

[0004] A burr grinding device for shaft parts proposed by the utility model realizes the sequential clamping of multiple workpieces by setting multiple groups of clamping components, and realizes the position switching of the grinding disc at each grinding station through setting a linear module. During the process of the grinding disc performing grinding operations at a certain grinding station, the clamping of workpieces can be completed at other grinding stations, and the grinding operations are carried out sequentially among multiple workpieces, making full use of the intermittent time between processes, so as to improve the production operation efficiency without increasing the labor intensity of the operators.

[0018] 2. By arranging a detection sensor in each clamping assembly to detect whether there is a workpiece clamped in the corresponding clamping assembly, if there is a workpiece, the grinding operation is carried out, and if there is no workpiece, the clamping position is automatically skipped, thereby automatically controlling the operation position of the grinding disc, avoiding ineffective empty operations, and thus improving the operation efficiency.

[0030] It should be noted that when a component is referred to as being "installed on" another component, it can be directly on the other component or there may also be an intermediate component. When a component is considered to be "arranged on" another component, it can be directly arranged on the other component or there may be an intermediate component at the same time. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there may be an intermediate component at the same time.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0032] Please refer to Figures 1 to 7, A burr grinding device for shaft parts, including a bracket 1 and a workbench 2 fixedly arranged at the top end of the bracket 1. The bracket 1 is a frame structure welded by section steel, and the workbench 2 is an aluminum alloy rectangular plate. Under the condition of ensuring sufficient support strength during the operation of the device, the overall weight of the device is reduced as much as possible.

[0033] On one side of the top surface of the workbench 2, a linear module 3 driven by a servo motor 15 is fixedly arranged. A grinding motor 5 is arranged on the moving and positioning end of the linear module 3, and a grinding disc 6 is fixedly connected to the output shaft end of the grinding motor 5. The fixed-distance feeding and fixed-point positioning of the grinding motor 5 are realized through the linear module 3, so that the grinding motor 5 and the grinding disc 6 can be quickly and accurately positioned at the grinding stations of each workpiece 12. The grinding motor 5 drives the grinding disc 6 to rotate continuously at a high speed, so as to carry out the grinding and removal operation on the burrs on the top surface of the workpiece 12.

[0034] Preferably, in order to facilitate the adjustment of the grinding position and angle of the grinding disc 6 to meet the surface deburring operation requirements of various types of workpieces 12, an adjustment component 9 is fixedly arranged on the moving and positioning end of the linear module 3. As Figure 3 and Figure 4 shown, the adjustment component 9 includes a positioning mounting plate 901 fixedly connected to the top end of the moving and positioning end, and an angular position adjustment plate 902 rotatably connected to one side of the top surface of the positioning mounting plate 901. A first adjustment screw 903 is rotatably arranged on the top surface of the positioning mounting plate 901. A nut block 904 is threadedly sleeved on the first adjustment screw 903. The top of the nut block 904 is rotatably connected to a connecting rod 905, and the top end of the connecting rod 905 is hinged to the top of the bottom surface of the angular position adjustment plate 902. By manually rotating the first adjustment screw 903, the nut block 904 can be driven to move horizontally forward and backward through screw transmission, so as to push the angular position adjustment plate 902 to rotate counterclockwise or clockwise relative to the positioning mounting plate 901 through the connecting rod 905, thereby synchronously adjusting the inclination angle of the grinding motor 5 and the grinding disc 6. To ensure the stability of the angle adjustment process of the angular position adjustment plate 902, guide rods 909 parallel to both sides of the first adjustment screw 903 are fixedly arranged on the top surface of the positioning mounting plate 901. Both ends of the nut block 904 are respectively slidably sleeved on the two guide rods 909, so that the nut block 904 can move horizontally stably; the connecting rod 905 is arranged with one on the left and right sides of the top end of the nut block 904, and the top ends of the two connecting rods 905 are respectively hinged to the left and right sides of the top of the bottom surface of the angular position adjustment plate 902, so that the angular position adjustment plate 902 can maintain stability during the rotation process.

[0035] On the top surface of the angular position adjusting plate 902, a second adjusting screw 908 is rotatably arranged, and guide chute plates 906 located on both sides of the second adjusting screw 908 are fixedly arranged. A positioning slide plate 907 is slidably embedded in the guide chute plates 906. The positioning slide plate 907 is threadedly sleeved on the second adjusting screw 908. The grinding motor 5 is fixedly arranged on the bottom top surface of the positioning slide plate 907. The angular position adjusting plate 902 is in an overall "V" shape, and a notch is formed in the middle of its top surface. A connecting plate is arranged in the notch. The second adjusting screw 908 is located in the notch and is threadedly sleeved in the connecting plate. By manually rotating the second adjusting screw 908, the positioning slide plate 907 can be driven by screw transmission to extend downward or contract upward along the inclined direction on the top surface of the angular position adjusting plate 902, so as to horizontally adjust the grinding operation position of the grinding motor 5 and the grinding disc 6.

[0036] A plurality of clamping assemblies 7 are fixedly arranged on the top surface of the workbench 2 at equal intervals along the advancing direction of the moving and positioning end of the linear module 3. The clamping assemblies 7 are used for clamping the workpiece 12 with burrs to be ground. In this embodiment, the workpiece 12 is a shaft-like part formed by turning. This burr grinding device is mainly used for the machining burrs on the end face contour of the shaft-like part. As Figures 5 to 7 shown, the clamping assembly 7 includes a base plate 701, a fixed half mold 702 fixedly connected to one side of the top surface of the base plate 701, and a movable half mold 703 rotatably connected to the other side of the top surface of the base plate 701. Clamping grooves are formed on the opposite inner walls of the movable half mold 703 and the fixed half mold 702. After the movable half mold 703 and the fixed half mold 702 are closed, the two clamping concave molds form a clamping cavity matching the outer contour of the workpiece 12. The base plate 701 is a circular plate, and its edge is fixedly connected to the top surface of the workbench 2 by screws. Both the movable half mold 703 and the fixed half mold 702 are semi-cylindrical structures. The outer bottom end of the fixed half mold 702 is fixedly connected to the top surface of the base plate 701 by screws, and the surface where its clamping groove is located faces right (in the Figure 1 direction shown as the operator's perspective); the inner bottom end of the bottom surface of the movable half mold 703 is rotatably connected to the top surface of the base plate 701 by a rotating shaft, and the surface where its clamping groove is located faces left, so that the movable half mold 703 can rotate relative to the fixed half mold 702. When the movable half mold 703 rotates to the right, the clamping cavity is in an open state. In this state, the workpiece 12 with burrs to be ground and polished can be placed laterally into the clamping groove of the fixed half mold 702, and then the movable half mold 703 is rotated to the left to be closed with the fixed half mold 702, and the workpiece 12 can be accurately clamped.

[0037] Preferably, an elastic clamping plate 704 is fixedly connected to the outer wall edge of the free end of the movable half-mold 703, and a clamping projection 705 that cooperates with the clamping plate 704 is fixedly provided on the outer wall edge of the fixed half-mold 702. A clamping notch is provided on the inner wall of the elastic clamping plate 704. When the movable half-mold 703 rotates to the left and approaches the fixed half-mold 702, the end of the elastic clamping plate 704 is slightly outwardly expanded under the action of the arc surface of the clamping projection 705 and slides along the arc surface of the clamping projection 705. When the movable half-mold 703 and the fixed half-mold 702 are in the mold-closing state, the clamping projection 705 is exactly located within the clamping notch, and the end of the elastic clamping plate 704 is located on the left side of the clamping projection 705 and naturally rebounds inwardly to fit against the outer wall of the fixed half-mold 702, thereby realizing the position locking between the movable half-mold 703 and the fixed half-mold 702 through the elastic clamping plate 704 to prevent the movable half-mold 703 from loosening during the deburring operation, causing the workpiece 12 to fall off from the clamping assembly 7 or shift in position. When an external force is manually applied to rotate the movable half-mold 703 to the right and separate it from the fixed half-mold 703, the end of the elastic clamping plate 704 is transferred to the right side of the clamping projection 705 in the same manner and disengages from the clamping projection 705, thereby realizing the opening of the clamping assembly 7. In this state, the workpiece 12 can be taken out from the clamping groove of the fixed half-mold 702 from the side to complete the blanking of the workpiece 12.

[0038] Furthermore, for the convenience of rotating the movable half-mold 703, a handle connecting plate 707 facing the operator is fixedly provided on the outer wall of the movable half-mold 703, and an operating handle 706 is rotatably connected to the top end of the handle connecting plate 707. By manually holding the operating handle 706, the rotation of the movable half-mold 703 can be conveniently and quickly completed.

[0039] To facilitate the detection of whether a workpiece 12 is clamped on the clamping assembly 7, a detection sensor 14 is provided at the inner bottom end of each clamping assembly 7, and a controller 4 is provided below the workbench 2. The controller 4 is electrically connected to the servo motor 15, the grinding motor 5, and each detection sensor 14 respectively. The detection sensor 14 can be any one of an infrared sensor, an ultrasonic sensor, or a photoelectric sensor. For this reason, in this embodiment, through holes communicating with the bottom end of the clamping cavity are formed in the inner walls of the movable half-mold 703 and the fixed half-mold 702, and an embedding groove located directly below the through hole is formed on the top surface of the base plate 701. The detection sensor 14 is fixedly embedded in the embedding groove, and the detection end faces the clamping cavity. When the workpiece 12 is clamped in the clamping assembly 7, the detection sensor 14 detects that there is an object above it, and thus sends a detection signal to the controller 4. The controller 4 then controls the servo motor 15 to work according to the signal source of the detection sensor 14, and drives the grinding motor 5 and the grinding disc 6 to move above the clamping assembly 7 corresponding to this detection sensor 14 through the linear module 3, so as to perform deburring operations on the workpiece 12 in this clamping assembly 7. If the detection sensor 14 does not detect an object above it, the signal state of this detection sensor 14 remains unchanged, and the linear module 3 drives the grinding motor 5 and the grinding disc 6 to skip the position of the clamping assembly 7 corresponding to this detection sensor 14 until reaching the position of the next clamping assembly 7 with a workpiece 12. In this way, ineffective operations at the grinding stations without workpieces 12 can be effectively avoided, and the operation efficiency can be improved.

[0040] Since in this device, only the start-stop control of the grinding motor 5 and the servo motor 15 and the signal processing of the detection sensor 14 are involved to achieve the corresponding logic control, the controller 14 can use a general controller with a single-chip microcomputer chip as the control core. Corresponding modifications can be made to the corresponding control programs in the controller 14. A supporting plate 13 is fixedly connected inside the bottom of the bracket 1, and the controller 14 is fixedly installed on the supporting plate 13, so that the controller 14 is as far away from the grinding operation area as possible.

[0041] Preferably, to facilitate the cleaning of the burr particles after grinding, a plurality of uniformly distributed discharge holes are formed on the top surface of the workbench 2, and a plurality of discharge funnels 8 located below the discharge holes are fixedly connected to the bottom surface of the workbench 2. The bottom end of the discharge funnel 8 penetrates below the bottom surface of the supporting plate 13, and a storage box 10 located below the bottom discharge end of the discharge funnel 8 is placed inside the bottom of the bracket 1. The burr particles generated during the grinding operation directly fall into the discharge holes or stay on the top surface of the workbench 2. The operator can send the burrs into the discharge holes through a brush. The burr particles fall from the discharge holes into the discharge funnels 8, and then gather towards the middle along the inner wall of the discharge funnels 8 and fall into the storage box 10, realizing the centralized collection and treatment of the burr particles.

[0042] Further preferably, a guard plate 11 with a rectangular frame structure is fixedly connected to the top surface of the workbench 2 and is located outside the discharge hole, which is used to confine the burr particles generated during the grinding operation to a fixed falling area, prevent the burr particles from scattering to areas outside the workbench 2, facilitate the centralized collection of burr particles, and improve the working environment at the same time.

[0043] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
