Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing equipment technology, and in particular relates to a chamfering device for processing metal parts. Background Technology

[0002] Machining refers to the process of changing the shape, size, or properties of a workpiece using mechanical equipment. The machining process involves many steps, such as clamping, cutting, transferring, and chamfering the workpiece. Through a series of machining steps, the workpiece is made into the required shape and size.

[0003] In machining, the processing of internal grooves is generally achieved using a lathe and cutting tools. Typically, a tool holder is used to hold the tool, which is then inserted into the groove's machining position for processing. However, the edges of grooves require chamfering. Chamfering of the groove edges is mostly done manually. One method involves a motor fixed to the worktable, with a chamfering tool at the motor's output. The worker holds the workpiece and places it on the end of the chamfering tool for chamfering; alternatively, a fixture is provided on the worktable for positioning the workpiece. The worker attaches the chamfering tool to the end of an electric drill and then uses the drill to chamfer the groove edges.

[0004] However, manual chamfering makes it difficult to guarantee the chamfer angle and uniformity, poses safety hazards during operation, and results in products that do not easily meet actual requirements, leading to a high defect rate and increased processing time. The time-consuming nature of manual chamfering significantly reduces processing efficiency. Therefore, there is an urgent need to design a chamfering device for metal parts processing to solve these problems. Summary of the Invention

[0005] This invention provides a chamfering device for metal parts processing with a reasonable structural design to solve the technical problems existing in the prior art. This invention replaces manual operation with mechanical linkage, eliminating safety hazards and improving processing efficiency through multi-station parallel processing. Simultaneously, the precise cooperation between guide rails and cylinder drive ensures consistent chamfering quality.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A chamfering device for metal parts processing includes a frame, a transverse drive assembly mounted on the frame, a clamping and positioning assembly mounted on the moving end of the transverse drive assembly, and a chamfering assembly disposed beside the transverse drive assembly. The chamfering assembly is slidably connected to the frame via a fine-tuning guide pair. A fine-tuning cylinder mounted on the frame is also included to drive the chamfering assembly to move along the fine-tuning guide pair. The extending direction of the fine-tuning guide pair is perpendicular to the running direction of the moving end of the transverse drive assembly. The clamping and positioning assembly includes a support structure mounted on the moving end of the transverse drive assembly, and multiple sets of transversely arranged shifting guide pairs are fixedly connected to the support structure and movably connected to an operating mechanism via the shifting guide pairs. The platform structure includes a shifting guide pair extending perpendicular to the moving end running direction of the clamping and positioning component, and a shifting cylinder for driving the platform structure to move along the shifting guide pair. At least two installation stations are provided on the platform structure, distributed along the extension direction of the shifting guide pair.

The frame serves as the basic support structure. The lateral movement drive component and the clamping and positioning component form a horizontal movement system, allowing multiple workpieces to enter the processing area in batches. The fine-tuning guide rail pair and the fine-tuning cylinder constitute the horizontal fine-tuning system of the chamfering component, enabling the chamfering cutter head to accurately contact the left and right edges of the workpiece's inner groove. The vertical adjustment of the chamfering cutter head, achieved by the lifting cylinder, ensures precise contact with the upper and lower edges of the workpiece's inner groove. The combination of the shifting guide rail pair and the shifting cylinder in the clamping and positioning component enables multi-station switching. Symmetrical clamping forces formed by two sets of clamping mechanisms ensure workpiece positioning stability. The chamfering component adopts a lifting motor drive structure. The vertical movement of the cutter head covers the upper and lower edges of the inner groove, combined with the lateral feed of the workpiece, to complete the chamfering process. The overall solution replaces manual operation with mechanical linkage, which not only eliminates safety hazards, but also improves processing efficiency through multi-station parallel processing. At the same time, the precise cooperation between guide rail and cylinder drive ensures consistent chamfer quality.

[0016] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided in detail: Please see Figure 1 The chamfering device for metal parts processing of this utility model includes a frame 1, a transverse drive assembly 3 mounted on the frame 1, a clamping and positioning assembly 2 mounted on the moving end of the transverse drive assembly 3, and a chamfering assembly 4 disposed on the side of the transverse drive assembly 3. The chamfering assembly 4 is slidably connected to the frame 1 through a transversely disposed fine-tuning guide pair 6. The device also includes a fine-tuning cylinder 5 mounted on the frame 1 for driving the chamfering assembly 4 to move along the fine-tuning guide pair 6. The extending direction of the fine-tuning guide pair 6 is perpendicular to the running direction of the moving end of the transverse drive assembly 3. like Figure 2As shown, the clamping and positioning assembly 2 includes a support structure 2-1 mounted on the frame 1. Multiple sets of transversely arranged shift guide rail pairs 2-4 are fixedly connected to the support structure 2-1 and are movably connected to the operating table structure through the shift guide rail pairs 2-4. The extension direction of the shift guide rail pairs 2-4 is perpendicular to the running direction of the moving end of the clamping and positioning assembly 2. It also includes a shift cylinder 2-3 for driving the operating table structure to move along the shift guide rail pairs 2-4. At least two installation stations 2-6 are provided on the operating table structure, distributed along the extension direction of the shift guide rail pairs 2-4. Two sets of clamping mechanisms 2-10 are provided opposite to each other on each installation station 2-6 for clamping the workpiece 7 to be processed. like Figure 5 As shown, the chamfering assembly 4 includes a chamfering support 4-1 slidably connected to the frame 1 via a transversely arranged fine-tuning guide rail pair 6. The chamfering support 4-1 is connected to the extended end of the fine-tuning cylinder 5. It also includes a cylinder support 4-8 mounted on the chamfering support 4-1. A chamfering motor 4-6 is movably connected to the cylinder support 4-8. A chamfering cutter head 4-2 is mounted on the output shaft of the chamfering motor 4-6. It also includes a lifting cylinder 4-9 mounted on the cylinder support 4-8 for driving the chamfering motor 4-6 to move up and down. The lifting cylinder 4-9 drives the rotating chamfering cutter head 4-2 to move up and down, which can realize the chamfering operation of the upper and lower groove edges of the inner groove of the workpiece 7. The transverse drive assembly 3 drives the clamping and positioning assembly 2 to clamp and position several workpieces 7 to move laterally toward / away from the rotating chamfering cutter head 4-2, which can realize the chamfering operation of the inner groove of the workpiece 7 and facilitate loading and unloading.

[0017] like Figure 6 As shown, the workpiece 7 to be processed has a rectangular shape and mainly includes a workpiece body 7-1. An inner groove 7-2 extending along its length is provided on the workpiece body 7-1.

[0018] Furthermore, the chamfering assembly 4 also includes a plurality of longitudinally arranged lifting guide rods 4-5 fixedly connected to the cylinder support 4-8. A lower lifting seat 4-4 and an upper lifting seat 4-7 are slidably connected between the plurality of lifting guide rods 4-5 via linear bearings. The extended end of the lifting cylinder 4-9 is connected to the upper lifting seat 4-7. The chamfering motor 4-6 is mounted on the upper lifting seat 4-7. The assembly also includes a shaft mounted on the output shaft of the chamfering motor 4-6. The shaft is rotatably connected to the lower lifting seat 4-4 via rolling bearings. The assembly also includes a tool shaft sleeve 4-3 for mounting the chamfering cutter head 4-2 connected to the shaft.

[0019] The longitudinally arranged lifting guide rod 4-5 forms a double-guide structure with the lower lifting seat 4-4 and the upper lifting seat 4-7 via linear bearings. When the lifting cylinder 4-9 drives the upper lifting seat 4-7 to move along the lifting guide rod 4-5, the chamfering motor 4-6 rises and falls synchronously with the upper lifting seat 4-7. At this time, the shaft maintains its rotational freedom under the support of rolling bearings, avoiding lateral loads on the motor output shaft caused by the lifting motion. The lower lifting seat 4-4 forms auxiliary support by sliding on the lifting guide rod 4-5 via linear bearings, and together with the upper lifting seat 4-7, constitutes a layered lifting mechanism, enhancing the structural rigidity of the cutter head during the lifting process. The cutter shaft sleeve 4-3 is connected to the shaft via a key to achieve power transmission, ensuring the perpendicularity of the rotation center of the chamfering cutter head 4-2 to the lifting motion trajectory and eliminating tool offset.

[0020] The above-mentioned design effectively suppresses the offset phenomenon during the lifting and lowering process of the chamfering cutter head 4-2. The combination of the layered lifting structure and rolling bearings ensures that the cutter maintains precise alignment with the inner groove 7-2 of the workpiece during the combined lifting and rotating motions. The combination of the lifting guide rod 4-5 and the linear bearing significantly reduces the resistance of the lifting motion. Simultaneously, the auxiliary support of the shaft by the lower lifting seat 4-4 greatly reduces the radial runout of the cutter head when subjected to cutting reaction forces, ensuring the dimensional accuracy and surface quality consistency of the chamfering operation on the upper and lower edges of the inner groove 7-2.

[0021] See further Figure 2 At each installation station 2-6, two sets of positioning frames 2-7 are arranged opposite each other, and several positioning blocks 2-8 are arranged between the two sets of positioning frames 2-7. Two sets of clamping mechanisms 2-10 are arranged opposite each other and are located on the outside of the corresponding two sets of positioning frames 2-7. A gap is left between the corresponding positioning blocks 2-8 and the positioning frames 2-7 to allow the clamping end of the clamping mechanism 2-10 to pass through. The gap refers to the channel space with a certain width reserved between the positioning frames 2-7 and the positioning blocks 2-8. Specifically, it can be formed by adjusting the installation position of the positioning blocks 2-8 to allow the clamping end of the clamping mechanism 2-10 to pass through and contact the side wall of the workpiece.

[0022] The positioning frame 2-7 refers to a rigid frame structure used to define the lateral position of the workpiece. Specifically, it can be implemented using a U-shaped steel component with a vertical positioning surface, and its inner wall forms a reference surface for placing the workpiece. The positioning block 2-8 refers to an adjustable support unit set between the two sets of positioning frames 2-7. Specifically, it can be a metal block with threaded holes, which is fixed to the mounting plate 2-11 by bolts to provide longitudinal support points for the workpiece.

[0023] Specifically, the workpiece is placed within the reference positioning area formed by the two sets of positioning frames 2-7. Longitudinal positioning is achieved by adjusting the position of the positioning block 2-8 to contact the bottom surface of the workpiece. After the clamping mechanism 2-10 is activated, the gripper 2-10-3 moves laterally along the clamping guide pair 2-10-6, and the clamping end passes through the gap between the positioning frame 2-7 and the positioning block 2-8 to contact both sides of the workpiece to complete the clamping. Because the clamping action occurs outside the positioning frame 2-7, collision interference with the positioning reference surface is avoided during the clamping process. The gap design between the positioning block 2-8 and the positioning frame 2-7 ensures a smooth movement path for the clamping end, while the rigid structure of the positioning frame 2-7 effectively suppresses lateral displacement of the workpiece during chamfering.

[0024] like Figure 3 As shown, the clamping mechanism 2-10 includes two sets of clamping guide rail pairs 2-10-6 coaxially arranged on the mounting station plate 2-11. Each clamping guide rail pair 2-10-6 is equipped with a gripper 2-10-3. A grooved mounting block 2-10-4 is installed on the inner side of the outer end of each gripper 2-10-3. A clamping buffer block 2-10-5 is detachably connected to the inner side of each grooved mounting block 2-10-4. The mechanism also includes two sets of clamping cylinders 2-10-1 mounted on the mounting station plate 2-11 for driving the two grippers 2-10-3 to move laterally along their respective clamping guide rail pairs 2-10-6. An end mounting block 2-10-2 is installed at the protruding end of each clamping cylinder 2-10-1. The two end mounting blocks 2-10-2 are detachably connected to the two grippers 2-10-3 respectively.

[0025] Among them, the clamping guide pair 2-10-6 refers to the guiding mechanism composed of linear guide rails and sliders. Specifically, it can be implemented by using ball linear guide rails in conjunction with slider components. The rigid guiding system is formed by the parallel arrangement of the double guide rails to ensure the straightness of the movement trajectory of the gripper 2-10-3 during the clamping process.

[0026] The slotted mounting block 2-10-4 refers to a metal connector with a T-slot or dovetail groove, which can be made of aluminum alloy. It forms a mechanical interlock with the gripper 2-10-3 through its slotted structure, providing a stable mounting surface for the buffer block. The clamping buffer block 2-10-5 refers to a contact component made of elastic material, such as polyurethane or rubber. It forms a detachable connection with the slotted mounting block 2-10-4 through bolts, absorbing impact energy during clamping. Specifically, when the clamping cylinder 2-10-1 is activated, the piston rod pushes the gripper 2-10-3 laterally along the clamping guide rail pair 2-10-6 via the end mounting block 2-10-2. The coaxial arrangement of the two guide rail pairs ensures that the gripper 2-10-3 always maintains a parallel movement trajectory. During the closing process of the gripper 2-10-3, the clamping buffer block 2-10-5 on the inner side of the grooved mounting block 2-10-4 first contacts the workpiece surface. The deformation generated by the elastic material provides clamping force and avoids rigid impact.

[0027] like Figure 2 As shown, the clamping and positioning assembly 2 also includes two sets of clamping limiting members 2-9 installed on each installation station 2-6, which are respectively set to correspond to the two sets of clamping mechanisms 2-10; the clamping limiting member 2-9 includes a positioning seat provided at the inner end of the clamping guide rail pair 2-10-6, and a positioning bolt pointing to the gripper 2-10-3 is screwed on the positioning seat for limiting the gripper 2-10-3.

[0028] The positioning seat can be machined from a metal block and fixed to the inner end of the clamping guide pair 2-10-6 with bolts, providing a mounting base for the positioning bolt. The positioning bolt can be a threaded adjusting rod, which achieves precise axial position control by screwing it into the threaded hole of the positioning seat. This structure constrains the travel of the gripper 2-10-3 through mechanical limiting, preventing overtravel when the clamping cylinder 2-10-1 is driven. Specifically, when the clamping cylinder 2-10-1 drives the gripper 2-10-3 to move along the clamping guide pair 2-10-6, the end of the positioning bolt forms a rigid block with the contact surface of the gripper 2-10-3. By rotating the positioning bolt, its extension length can be adjusted, thereby controlling the final position of the gripper 2-10-3 when it is closed.

[0029] like Figure 4As shown, the transverse drive assembly 3 includes a mounting base 3-1 mounted on the frame 1. The mounting base 3-1 is the basic support structure bearing the transverse drive assembly 3, and can be a welded or bolted metal frame structure to ensure the rigidity of the overall structure. Two sets of guide rail plates 3-6 are mounted on the mounting base 3-1, and the guide rail plates 3-6 are plate-shaped supports fixed to both sides of the mounting base 3-1, which can be made of steel plate and provide the mounting reference surface for the transverse guide rail pairs 3-5. Each guide rail plate 3-6 has a transverse guide rail pair 3-5 mounted on it, and a transverse mounting seat 3-4 is slidably connected to the transverse guide rail pair 3-5. The assembly also includes a transverse lead screw 3-3 rotatably connected to the mounting base 3-1 and arranged parallel to the transverse guide rail pairs 3-5. The transverse mounting seat 3-4 is connected to the transverse lead screw 3-3 via a nut. Finally, the assembly includes a transverse motor 3-2 for driving the transverse lead screw 3-3 to rotate. A motor mount for mounting a transverse motor 3-2 is mounted on the mounting base 3-1. A strip-shaped hole extending axially along the transverse lead screw 3-3 is provided on the motor mount. The motor mount is detachably connected to the mounting base 3-1 by bolts and lock nuts passing through the strip-shaped hole.

[0030] When the transverse motor 3-2 drives the lead screw to rotate, the lead screw nut drives the transverse mounting base 3-4 to move linearly along the guide rail pair, and the clamping and positioning component 2 moves synchronously with the transverse mounting base 3-4. The symmetrical layout of the two sets of guide rail pairs forms a double-rail guiding structure, effectively suppressing skew and vibration during movement. The lead screw transmission mechanism, through closed-loop control of the servo motor, can achieve micron-level positioning accuracy, ensuring the positional stability of the workpiece during the chamfering process.

[0031] To address the dust pollution problem generated during the chamfering process of metal parts, and to prevent dust accumulation from affecting equipment operating accuracy and the cleanliness of the operating environment, such as... Figure 2 As shown, the support structure 2-1 is hollow. A dust collection hood 8 is installed inside the support structure 2-1. An air outlet connected to the dust collection hood 8 is provided on the side wall of the support structure 2-1 away from the chamfered component 4. The air outlet is connected to the lower air outlet of the dust collection hood 8 through a gas pipeline. In addition, a gas pipeline and a fan are connected to the air outlet. The fan is connected to the dust collector / dust remover through the gas pipeline.

[0032] The hollow structure refers to a frame-like structure that forms a sealed cavity inside the support. Specifically, it can be implemented using welded steel plates to form a box-shaped structure. Its function is to provide installation space for the dust collection hood 8 and form a dust collection channel. The dust collection hood 8 is a dust collection component that covers the processing area. Specifically, it can be implemented using a funnel-shaped or horn-shaped metal shell, with its opening facing the contact area between the chamfered cutter head 4-2 and the workpiece, to capture splashed metal debris. The air outlet is an airflow channel located on the side wall of the support. Specifically, it can be implemented using a flanged circular pipe opening, which communicates with the inner cavity of the dust collection hood 8 to form a dust conveying path. The gas pipeline is the piping system connecting the air outlet to the dust removal equipment. Specifically, it can be implemented using corrugated flexible hoses or rigid metal pipes, used to guide the dust-laden airflow in a directional manner.

[0033] In actual operation, when the chamfering cutter head 4-2 comes into contact with the workpiece and generates metal dust, the fan starts and creates a negative pressure airflow in the gas pipeline. The dust collection hood 8 confines the dust generated in the processing area within its coverage area, and the dust-laden air enters the gas pipeline through the dust collection hood 8 and the air outlet. Driven by the fan, the airflow continues to flow towards the dust collector or dust remover, where dust particles are trapped in the filtration device, and the purified air is discharged from the system. In this process, the hollow structure of the support serves as both a mechanical support component and a dust transmission channel, achieving an integrated structural and functional design.

[0034] like Figure 6 As shown, the chamfering cutter head 4-2 includes an integrally formed shaft and a disc-shaped chamfering cutter head. The upper and lower edges of the outer peripheral wall of the chamfering cutter head are arc-shaped and adapted to the inner groove edge on the workpiece.

[0035] The integrally formed and coaxially aligned shaft and the disc-shaped chamfered cutter head 4-2 refer to a single structure where the cutter head and drive shaft are formed without assembly gaps through integral machining processes. This can be achieved through forging or CNC machining, thereby eliminating coaxiality deviations caused by separate connections and ensuring uniform force distribution during cutter head rotation. The arc-shaped upper and lower edges of the outer peripheral wall ensure that the contour shape of the cutter head's cutting area perfectly matches the geometric features of the inner groove 7-2 edge of the workpiece. This allows the chamfer angle to be directly defined by the cutter shape, avoiding errors from manual adjustment. The arc-shaped contours of the cutter head's upper and lower edges, through preset geometric matching, automatically form a chamfer surface with the curvature of the inner groove 7-2 edge when the cutter enters the workpiece, eliminating the need for operator experience to adjust the cutter angle.

[0036] See further Figure 2 The operating table structure includes a shift seat plate 2-5 connected to the slider in the shift guide pair 2-4. Two sets of shift seat plates 2-5 are provided. It also includes an installation station plate 2-11 installed between the two sets of shift seat plates 2-5. The bottom surface of the installation station plate 2-11 is clearance-fitted with the top surface of the support structure 2-1.

[0037] The displacement seat plate 2-5 is a load-bearing component rigidly connected to the slider of the displacement guide rail pair 2-4. It can be formed by welding or casting steel plates, and its connection to the guide rail slider is achieved through bolts for power transmission. This structure distributes the moving load through a symmetrical layout of the two seat plates, reducing the risk of guide rail deformation caused by single-point stress.

[0038] like Figure 5 As shown, the chamfered support 4-1 includes two support plates mounted vertically, with several support rods connecting the two plates together. A T-slot is provided on the lower support plate for movably connecting with the extended end of the fine-tuning cylinder 5. The T-slot is a guide groove with a T-shaped cross-section, located on the bottom surface of the lower support plate. Specifically, it can be a machined groove with a width of 15-25 mm and a depth of 8-12 mm. The T-slot sidewall and the cylinder connector form a bidirectional constraint, preventing lateral displacement during the driving process.

[0039] Working principle: After the workpiece is fixed to the operating table by the clamping mechanism 2-10, the transverse drive assembly 3 pushes the workpiece horizontally close to the chamfering cutter head 4-2. When the chamfering motor 4-6 drives the cutter head to rotate, the lifting cylinder 4-9 controls the vertical movement of the cutter head to complete the upper and lower groove edge processing. Then, the fine-tuning cylinder 5 controls the left and right movement of the cutter head to complete the left and right groove edge processing of the workpiece. The shifting cylinder 2-3 drives the transverse displacement of the operating table to switch positions, realizing the alternating processing of multiple workpieces. The buffer block in the clamping mechanism 2-10 cooperates with the positioning bolt to ensure uniform distribution of clamping force. The special cutting edge shape of the chamfering cutter head 4-2 matches the lifting motion trajectory to ensure consistent chamfering angle. Compared with the existing technology, traditional manual chamfering requires multiple adjustments to the workpiece posture. This solution achieves automatic positioning through orthogonal dual-axis linkage. Existing equipment mostly uses single-station fixed fixtures. This device's multi-station parallel design greatly improves processing efficiency. Compared with handheld tool operation, the enclosed processing process of this device completely eliminates safety hazards.
