Technical Field

[0001] This application relates to the field of machining equipment technology, and in particular to a clamping fixture and a cutting and marking device. Background Technology

[0002] In the production of circular insulators, especially in machining processes such as cutting and marking, it is often necessary to quickly and reliably position and clamp the workpiece or product. Typically, hydraulic or pneumatic clamping devices are used to hold the workpiece. However, when using large-stroke hydraulic or pneumatic clamping devices, the smaller the size of the workpiece to be clamped, the greater the extension length of the telescopic rod needs to extend, which can easily lead to deformation of the telescopic rod, resulting in limited adjustment range and poor versatility. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a clamping fixture and cutting and marking device that can adapt to the clamping of circular insulators of different sizes, especially small workpieces, effectively avoid deformation of the clamping rod, and improve the stability, reliability and versatility of the clamping fixture.

[0004] This application provides the following technical solution: This application embodiment provides a clamping fixture, the clamping fixture comprising: A carrier component having a bearing end face for bearing a workpiece; A limiting member, wherein the limiting member is disposed on the bearing member; A driving component and an adjusting component are connected to the driving component. The adjusting component can adjust the distance between the driving component and the limiting component. The driving component can push the workpiece to move towards the limiting component, so that the workpiece is clamped between the limiting component and the driving component.

[0005] In some embodiments of the first direction, the limiting member includes a pair of limiting blocks spaced apart from the carrier, such that the workpiece is in a clamped state and the pair of limiting blocks can respectively abut against the two sides of the end of the workpiece away from the driving member.

[0006] In some embodiments of the first direction, the limiting member is rotatably disposed on the carrier member, and the rotation axis of the limiting member is perpendicular to the carrier end face; wherein, the limiting block has a limiting end face, and the limiting end face is used to abut against the workpiece.

[0007] In some embodiments of the first direction, the limiting end face and the bearing end face are arranged perpendicularly.

[0008] In some embodiments of the first direction, the bearing end face is provided with a buffer layer.

[0009] In some embodiments of the first direction, the adjusting member includes: A base, wherein the base and the bearing member are slidably connected, the sliding direction of the base and the pushing direction of the driving member are arranged parallel to each other, and the driving member is disposed on the base; A rack is disposed on the bearing member, and the extending direction of the rack is parallel to the sliding direction of the base; The insert teeth are movably disposed on the base, so that the insert teeth can selectively engage with the rack.

[0010] In some embodiments of the first direction, the insert tooth is rotatably disposed on the base, and the rotation of the insert tooth is configured to enable the insert tooth and the rack to switch between an engaged state and an unengaged state.

[0011] In some embodiments of the first direction, the number of racks is a pair, and each rack is provided with a corresponding insert tooth; wherein the racks are anti-reverse racks, and the anti-reverse directions of the pair of racks are arranged oppositely.

[0012] In some embodiments of the first direction, the driving member is configured as a telescopic rod, the telescopic end of which is used to abut the workpiece, and the fixed end of which is disposed on the adjusting member.

[0013] Secondly, embodiments of this application also provide a notch marking device, the notch marking device comprising: Clamping fixture as described in any of the above embodiments; A rotary drive assembly is connected to the carrier member, the rotary drive assembly is used to drive the carrier member to rotate, and the rotation axis of the carrier member is perpendicular to the carrier end face; A linear drive assembly is connected to the rotary drive assembly. The linear drive assembly is used to drive the rotary drive assembly to move, so that the clamping fixture passes through the cutting station and the marking station in sequence.

[0014] The embodiments of this application have the following advantages: This application provides a clamping fixture that clamps a workpiece through the coordinated action of a driving component and a limiting component. First, the circular insulator workpiece to be processed is placed on the bearing end face of a carrier component. The distance between the driving component and the limiting component is adjusted using an adjusting component to accommodate the actual size of the workpiece. The driving component (which can be pneumatic or hydraulic) is activated, pushing the workpiece towards the limiting component, thus stably pressing the workpiece between the driving component and the limiting component, completing the clamping operation. Throughout the process, the adjusting component can pre-adjust the driving stroke to prevent the driving component's telescopic rod from extending too far, thereby structurally avoiding deformation problems caused by large strokes.

[0015] Therefore, by flexibly adjusting the distance between the driving component and the limiting component through the adjusting mechanism, it can adapt to circular insulator workpieces of different diameters, and is particularly optimized for clamping support of small-sized workpieces, effectively expanding the applicability of the tooling. The adjusting mechanism enables pre-adjustment of the driving stroke, avoiding excessive extension of the driving component (such as a hydraulic or pneumatic telescopic rod) when clamping small workpieces, thereby significantly reducing bending or deformation of the telescopic rod due to excessive overhang, and improving the rigidity and stability of clamping. The tooling structure is rationally designed, organically combining load-bearing, limiting, driving, and adjusting functions. It is easy to operate and can quickly complete workpiece clamping and release, which is conducive to improving production efficiency.

[0025] In the production of circular insulators, especially during machining processes such as cutting and marking, it is often necessary to quickly and reliably position and clamp the workpiece 300 or the product. Typically, hydraulic or pneumatic clamping devices are used to hold the workpiece 300. However, when using large-stroke hydraulic or pneumatic clamping devices, the smaller the size of the workpiece 300 to be clamped, the greater the extension length of the telescopic rod needs to be, which can easily lead to deformation of the telescopic rod, resulting in limited adjustment range and poor versatility.

[0026] As shown in Figure 1 and Figure 3 As shown, to solve the above-mentioned technical problems, this application provides a clamping fixture, which includes a carrier 100, a limiting member, a driving member 400, and an adjusting member 500. The carrier 100 has a bearing end face 110 for bearing a workpiece 300. The limiting member is disposed on the carrier 100. The adjusting member 500 is connected to the driving member 400, and the adjusting member 500 can adjust the distance between the driving member 400 and the limiting member. The driving member 400 can push the workpiece 300 towards the limiting member, so that the workpiece 300 is clamped between the limiting member and the driving member 400.

[0027] In these embodiments, a clamping fixture is provided for rapid, stable, and adjustable clamping and positioning during the cutting or marking process of circular insulators. Of course, it is not limited to circular insulators; other circular workpieces 300 can also be used, as long as they can be adapted for clamping.

[0028] The support member 100 is a rectangular base 520 structure made of high-strength aluminum alloy, with a horizontally positioned support end face 110. This support end face 110 is used to stably place the circular insulator to be processed, preventing relative slippage of the workpiece 300 during clamping. The bottom of the support member 100 can be fixed to the machine tool worktable with screws to ensure the overall structural stability.

[0029] A limiting member is fixedly mounted on one end of the carrier 100. For example, it can be installed via bolt connection or integral molding. The limiting member is in the shape of a vertical plate, with a flat limiting end face on the side facing the workpiece 300, serving as a reference stop during the clamping process. When the workpiece 300 is pushed, one end of the limiting member abuts against this limiting surface, thereby achieving precise axial positioning.

[0030] The drive component 400 is mounted on the support component 100 and located on the opposite side of the limiting component. In this embodiment, the drive component 400 employs a cylinder device, including a cylinder body and a telescopic piston rod. A pressure head is connected to the front end of the piston rod, and this pressure head is made of soft rubber material to avoid damaging the surface of the insulator. The cylinder is controlled by a solenoid valve to control the air supply and achieve automated reciprocating motion.

[0031] An adjusting member 500 is disposed on the support member 100 and connected to the driving member 400, for adjusting the distance between the driving member 400 and the limiting member. For example, the adjusting member 500 includes: The slide rail assembly has two parallel guide rails arranged along the length of the bearing member 100. The slider is mounted on the guide rail and can slide along the guide rail; The mounting plate is fixed to the slider, and the cylinder body is fixed to the mounting plate with screws. Locking mechanisms, such as tightening handles or quick-release pins, are used to lock the slider in any position on the guide rail after adjustment.

[0032] By manually pushing the mounting plate, the entire drive component 400 is moved along the guide rail, thereby changing the distance between it and the limiting component. This distance can be flexibly adjusted according to the different diameters or lengths of circular insulators. For example, for insulators with smaller diameters, the drive component 400 can be moved closer to the limiting component; while for larger workpieces 300, it can be adjusted outwards to expand the clamping range.

[0033] The operating steps are as follows: Loosen the locking mechanism and move the mounting plate to a suitable position, leaving a space slightly larger than the length of the workpiece 300 between the pressure head and the limiting surface. Place the circular insulator flat on the bearing end face 110, with one end lightly touching the limiting surface. Secure the position of the driving component 400 with the locking adjustment component 500. Start the air source; the cylinder piston rod extends, pushing the pressure head to press against the other end of the workpiece 300, completing the clamping process.

[0034] This embodiment effectively solves the problem of bending deformation caused by excessively long telescopic rods when clamping small-sized workpieces 300 in traditional large-stroke hydraulic / pneumatic clamps by setting an adjustable installation position for the drive component 400. Since the drive component 400 itself does not need to be designed with an ultra-long stroke, only a short stroke is needed to complete the clamping action, which significantly improves the structural rigidity and clamping stability.

[0035] In some embodiments, the limiting member includes a pair of limiting blocks 200, which are spaced apart from the carrier 100, so that when the workpiece 300 is in a clamping state, the pair of limiting blocks 200 can respectively abut against the two sides of the end of the workpiece 300 away from the driving member 400.

[0036] To meet the need to prevent rotation or displacement of circular insulators during processing, this embodiment provides an improved limiting structure that can achieve bidirectional lateral positioning of the workpiece 300 end, further improving clamping stability.

[0037] The limiting component includes a pair of limiting blocks 200, which are detachably mounted on the carrier 100 by screws and are spaced apart in a direction perpendicular to the axis of the workpiece 300 to form a U-shaped or V-shaped positioning groove that adapts to the width of the workpiece 300.

[0038] A pair of limiting blocks 200 are symmetrically arranged on the left and right sides of the placement path of the workpiece 300. When the workpiece 300 is in a clamped state, the end of it that is away from the drive member 400 extends into the interval area and the end face abuts against the imaginary reference plane (defined by the inner surfaces of the two limiting blocks 200). At the same time, the outer periphery of this end contacts or slightly abuts against the inner surfaces of the two limiting blocks 200 respectively.

[0039] The spacing between the limiting blocks 200 can be adjusted according to circular insulators of different diameters. For example, by providing strip holes or guide grooves on the carrier 100, the limiting blocks 200 can be allowed to slide laterally and lock, thereby adapting to workpieces 300 of a wide range of sizes.

[0040] Preferably, each limiting block 200 has an elastic buffer layer (such as a polyurethane gasket) on its inner side, which can absorb the impact caused by assembly errors and avoid scratching the surface of the insulator.

[0041] Compared to a single limiting plate that only provides axial stopping, the pair of limiting blocks 200 in this embodiment not only provide axial support but also provide anti-torsion and anti-slip capabilities. For the cylindrical workpiece 300, two-point contact can effectively limit its degree of freedom in the direction perpendicular to the axis, preventing minute rotation or displacement caused by cutting forces during marking or cutting. This is particularly suitable for high-precision machining scenarios, such as laser marking and CNC milling.

[0042] In some embodiments, the limiting member is rotatably disposed on the bearing member 100, and the rotation axis of the limiting member is perpendicular to the bearing end face 110; wherein, the limiting block 200 has a limiting end face, which is used to abut against the workpiece 300.

[0043] To enhance the adaptability of the clamping fixture to workpieces 300 with different shapes or installation angles, especially to achieve rapid changeover and flexible positioning in multi-process production lines, this embodiment provides a rotatable limiting component structure with its rotation axis perpendicular to the bearing end face 110, allowing for flexible adjustment of the limiting direction.

[0044] Based on any of the aforementioned embodiments, the limiting member is rotatably mounted on the bearing member 100 via a rotating shaft structure, and its rotation axis is perpendicular to the bearing end face 110, i.e., arranged in the vertical direction.

[0045] The limiting component is generally fan-shaped or rectangular, with a flat limiting end face on the side facing the workpiece 300. This end face is used to abut against the end face of the workpiece 300 opposite to the driving component 400 in the clamping state. During the clamping process, the driving component 400 pushes the workpiece 300 towards the limiting end face, and the limiting block 200 rotates adaptively to complete the clamping.

[0046] In some embodiments, the limiting end face and the bearing end face 110 are arranged perpendicularly.

[0047] To accommodate circular insulators of different shapes and sizes, especially in applications where strict control of the workpiece 300's orientation is required to ensure high-precision processing (such as cutting and marking), this embodiment provides an improved clamping fixture. The limiting end face and the bearing end face 110 are arranged perpendicularly, thereby enhancing the accuracy and stability of the workpiece 300's positioning.

[0048] Based on any of the above embodiments, the limiting member includes one or more limiting blocks 200, each limiting block 200 having a limiting end face. The limiting end face maintains a strict perpendicular relationship with the bearing end face 110 on the bearing member 100, that is, the angle between the two is 90 degrees.

[0049] To ensure the perpendicularity between the limiting end face and the bearing end face 110, the limiting block 200 is precision machined or directly integrated into the bearing component 100, and mechanical processing is used to ensure the perpendicularity between the two. The form of the limiting block 200 can be a single rectangular block, a pair of spaced-apart limiting blocks 200, or a rotatable and adjustable limiting block 200. However, regardless of the form, the limiting end face must be strictly perpendicular to the bearing end face 110.

[0050] The circular insulator to be processed is placed flat on the bearing end face 110, ensuring its bottom surface is completely in contact with the bearing surface. The workpiece 300 is initially positioned using any available guide grooves or locating pins. The drive unit 400 is activated, pushing the workpiece 300 forward until one end is in close contact with the limiting end face. Since the limiting end face is perpendicular to the bearing end face 110, the workpiece 300 will automatically correct itself to the correct vertical orientation. After clamping, the workpiece 300 is in a stable and accurate position, ready for subsequent processing operations.

[0051] In some embodiments, the bearing end face 110 is provided with a buffer layer.

[0052] To address the problems of surface damage, stress concentration, or microcracks in circular insulators caused by hard contact during clamping in existing clamping fixtures, especially when clamping insulators made of brittle materials (such as ceramics, glass fiber reinforced epoxy resin, etc.), this embodiment provides an improved load-bearing structure, characterized by: a buffer layer provided on the load-bearing end face 110 to absorb clamping impact, disperse contact stress, and prevent workpiece 300 from slipping.

[0053] Specific structure and material selection: Cushioning layer material: Non-metallic materials with elasticity and abrasion resistance can be used, such as rubber (e.g., silicone, nitrile rubber), polyurethane (PU), soft PVC, or micro-foamed materials. These materials have appropriate Shore hardness, providing sufficient support while effectively cushioning impacts.

[0054] Installation method: The buffer layer is attached to the bearing end face 110 using high-strength double-sided adhesive or structural adhesive. Alternatively, a groove is machined into the bearing end face 110 to embed and limit the buffer layer, preventing it from falling off.

[0055] The buffer layer is made into an independent pad, which facilitates regular replacement and extends the overall service life of the tooling.

[0056] For example, the surface of the buffer layer may be provided with an anti-slip texture (such as stripes, grids or dot matrix) to increase the friction with the bottom surface of the workpiece 300 and prevent slippage caused by processing vibration.

[0057] When the workpiece 300 is pushed and pressed against the limiting member by the driving member 400, its bottom surface always remains in contact with the buffer layer; the buffer layer generates slight elastic deformation in the vertical direction to absorb the impact energy at the moment of clamping; at the same time, its elastic properties help to evenly distribute the contact pressure between the workpiece 300 and the bearing surface, avoiding excessive local stress that could cause the insulator edge to crack or the internal structure to be damaged; in the process of cutting or marking, which involves large vibrations, the buffer layer can also play a role in vibration reduction and improve the processing accuracy.

[0058] In some embodiments, the adjusting member 500 includes a base 520, a rack 530, and a tooth 510. The base 520 and the support member 100 are slidably connected. The sliding direction of the base 520 is parallel to the pushing direction of the driving member 400, and the driving member 400 is disposed on the base 520. The rack 530 is disposed on the support member 100, and the extending direction of the rack 530 is parallel to the sliding direction of the base 520. The tooth 510 is movably disposed on the base 520, so that the tooth 510 can selectively engage with the rack 530.

[0059] To address the problem of traditional clamping fixtures failing to quickly and reliably lock the drive component 400 after adjustment, especially in production environments where different sizes of circular insulators are frequently replaced, a mechanical structure that can be both flexibly adjusted and precisely positioned is needed. This embodiment provides an improved adjustment component 500 structure, which achieves stepless adjustment and rigid locking of the drive component 400's mounting position through the cooperation of "base 520 + rack 530 + insert 510".

[0060] The base 520 is a rectangular metal plate structure made of aluminum alloy or steel, possessing sufficient structural strength. The base 520 is slidably mounted on the support member 100, and is guided, for example, by a guide rail-slider pair.

[0061] Specifically, two parallel guide rails are arranged along the length of the top of the support member 100, and a matching slider is provided at the bottom of the base 520, enabling the base 520 to perform linear reciprocating motion along the guide rails. The sliding direction of the base 520 is parallel to the pushing direction of the drive member 400 (i.e., the axial direction of the workpiece 300), ensuring that the clamping center line does not deviate during adjustment. The cylinder body of the drive member 400 (such as a cylinder) is fixedly mounted on the base 520 with screws and moves together with the base 520.

[0062] The rack 530 is fixedly disposed on one side of the bearing member 100, preferably arranged parallel to the side of the guide rail; the extension direction of the rack 530 is completely consistent with the sliding direction of the base 520; the rack 530 has a continuously distributed standard straight tooth profile with a moderate module, which facilitates meshing with the tooth 510; the rack 530 can be firmly installed on the bearing member 100 by screws or welding to prevent loosening.

[0063] The pick 510 is movably mounted on the base 520, specifically through a vertical through hole. The upper end of the pick 510 has a handle for easy manual operation. The lower end is a toothed section, its shape matching the rack 530, which can be inserted into the tooth groove of the rack 530 to achieve engagement when it moves downwards. When the position needs to be locked, press the handle of the insert 510 so that its lower teeth enter the tooth groove of the rack 530, forming a mechanical engagement and preventing the base 520 from moving relative to the carrier 100.

[0064] In some embodiments, the insert 510 is rotatably disposed on the base 520, and the rotation configuration of the insert 510 is such that the insert 510 and the rack 530 can switch between an engaged state and an unengaged state.

[0065] In these embodiments, an improved adjustment member 500 structure is provided. In this structure, the tooth 510 engages or disengages with the rack 530 by rotation, thereby replacing the manual lifting or pressing of the tooth 510, making the operation more intuitive, labor-saving and efficient.

[0066] The pick 510 is rotatably mounted on the base 520 and can switch between engaging and disengaging with the rack 530 by rotation.

[0067] The main body of the shaping tooth 510 is L-shaped or T-shaped, with a toothed section at one end and a handle at the other end. A rotating shaft is located in the middle of the shaping tooth 510, passing through a shaft hole on the base 520, allowing the shaping tooth 510 to rotate about an axis perpendicular to the sliding direction. The surface of the shaping tooth 510 near the rack 530 is designed with tooth profiles that match the rack 530. When the shaping tooth 510 rotates to a specific angle, these teeth will precisely mesh with the tooth grooves of the rack 530.

[0068] For example, to release the tooth 510: hold the handle and rotate the tooth 510 clockwise by about 90 degrees, so that the teeth of the tooth 510 are away from the rack 530. At this time, the tooth 510 enters a non-engaged state, and the base 520 can slide freely. Sliding base 520: Push the base 520 along the guide rail to move the driving component 400 together, and adjust the distance between it and the limiting component to accommodate circular insulators of different lengths; Once in position, lock the insert 510: Rotate the handle of insert 510 counterclockwise to return insert 510 to its initial position, that is, the teeth of insert 510 engage with rack 530 again, completing the quick locking.

[0069] In some embodiments, the number of racks 530 is a pair, and each rack 530 is provided with a corresponding insert tooth 510; wherein, the racks 530 are stop racks 530, and the stop directions of the pair of racks 530 are arranged in opposite directions.

[0070] To address the issue of potential unidirectional slippage or even unexpected backward movement of the fixture base 520 under high vibration or frequent start-stop conditions, particularly when the driving component 400 (such as a cylinder) applies a large thrust, the resulting reaction force may cause the adjustment mechanism to loosen. This embodiment provides an improved double rack 530 bidirectional locking structure. This structure employs a pair of anti-backlash racks 530 that engage with corresponding teeth 510 to rigidly limit the base 520 in both directions of movement, significantly improving clamping stability and safety.

[0071] The number of racks 530 is one pair, which are respectively disposed on the bearing member 100 and arranged in parallel along the sliding direction of the base 520; each rack 530 is correspondingly configured with a tooth 510 for selective engagement and locking.

[0072] The rack 530 is a "reverse-locking rack 530", meaning its tooth profile is asymmetrical and has a clearly defined "reverse-locking direction". Specifically, the tooth surface of the reverse-locking rack 530 has an approximately vertical blocking surface (working surface) on one side and an inclined guiding surface (introducing surface) on the other side. When an external force attempts to push the base 520 to move along the blocking surface direction, the insert 510 will be locked and cannot slip out; however, it can slide in or out smoothly along the inclined surface direction.

[0073] In a pair of racks 530: The first rack 530 is positioned away from the limiting member (i.e., to prevent the base 520 from sliding outwards). The anti-reverse direction of the second rack 530 is towards the direction close to the limiting member (i.e., to prevent the base 520 from moving inward). Therefore, the anti-reverse directions of the pair of racks 530 are set in opposite directions, forming a bidirectional locking capability.

[0074] Dual-tooth 510 configuration: Each rack 530 has a corresponding insert tooth 510, namely a first insert tooth 510 and a second insert tooth 510. The insert teeth 510 are slidably or rotatably disposed on both sides of the base 520.

[0075] When the inserter 510 is pressed down or rotated to the meshing position, its teeth are embedded in the tooth groove of the corresponding anti-reverse rack 530, and the one-way locking characteristic of the anti-reverse tooth shape prevents the base 520 from moving in that direction.

[0076] In some embodiments, the drive member 400 is configured as a telescopic rod, the telescopic end of which is used to abut against the workpiece 300, and the fixed end of the telescopic rod is disposed on the adjusting member 500.

[0077] In these embodiments, the drive member 400 is in the form of a telescopic rod, with its telescopic end directly contacting and pushing the workpiece 300, while the fixed end is mounted on the adjusting member 500, thereby achieving precise position adjustment and stable clamping effect.

[0078] The telescopic rod consists of two parts: a telescopic end and a fixed end. The telescopic end is the moving part of the telescopic rod, and its end is equipped with a pressure head or buffer pad (such as rubber, polyurethane, etc.) for direct contact and pressing against the surface of the workpiece 300 to prevent scratches or damage to the workpiece 300. The fixed end is installed on the base 520 of the adjusting component 500 and is securely connected by bolts or other fasteners. The telescopic rod can be pneumatic, hydraulic, or electric, and the specific choice depends on the needs of the application scenario.

[0079] like Figure 2 As shown, in some embodiments, this application also provides a notch marking device, the notch marking device comprising: Clamping fixture as described in any of the above embodiments; A rotary drive assembly 600 is connected to the carrier 100. The rotary drive assembly 600 is used to drive the carrier 100 to rotate. The rotation axis of the carrier 100 is perpendicular to the carrier end face 110. A linear drive assembly is provided, which is connected to the rotary drive assembly 600. The linear drive assembly is used to drive the rotary drive assembly 600 to move, so that the clamping fixture passes through the cutting station and the marking station in sequence.

[0080] To further improve production efficiency, reduce manual intervention, and ensure processing accuracy, this embodiment provides an integrated cutting and marking device, which not only includes the clamping fixture in any of the above embodiments, but also integrates a rotary drive component 600 and a linear drive component, realizing the automatic transfer of the workpiece 300 between different processes.

[0081] The clamping fixture is used to precisely clamp the circular insulator; this fixture ensures that the workpiece 300 maintains a stable position throughout the entire processing, providing a reliable basis for subsequent cutting and marking.

[0082] A rotary drive assembly 600 is positioned below the carrier 100 and connected to it via a coupling or direct connection. The rotary drive assembly 600 can be a servo motor, stepper motor, or other type of electric motor, capable of precisely controlling the rotation angle of the carrier 100. The rotation axis of the carrier 100 is perpendicular to the bearing end face 110, allowing the workpiece 300 to rotate freely in the horizontal plane, adapting to different directional cutting or marking requirements. In some applications, a reducer can be configured to increase torque output, ensuring that even large-sized workpieces 300 can be accurately rotated.

[0083] A linear drive assembly is mounted on the worktable to drive the rotary drive assembly 600 and its clamping fixture along a linear path. The linear drive assembly can be a linear module, a ball screw mechanism, or a synchronous belt drive system, depending on the required positioning accuracy and speed. The linear drive assembly can move the entire clamping fixture from its initial position sequentially through the cutting station and the marking station, completing a series of automated operations. It is usually equipped with sensors or limit switches to detect when the target position is reached and trigger corresponding actions (such as starting a cutting machine or laser marking machine).

[0084] First, place the circular insulator to be processed on the bearing end face 110 of the clamping fixture, and then firmly clamp it using the driving component 400.

[0085] The linear drive assembly moves the entire device along the guide rail to the cutting station. At this time, the rotary drive assembly 600 can remain stationary or finely adjust the workpiece angle 300 as needed.

[0086] Upon reaching the cutting station, the cutting equipment (such as a CNC cutting machine) begins to work, forming an opening of the required shape on the surface of the workpiece 300. After the cutting is completed, the linear drive component starts again, transporting workpiece 300 to the next station: the marking station.

[0087] At the marking station, a laser marking machine or other marking equipment marks the workpiece 300.

[0088] After all processes are completed, the linear drive assembly returns to the starting position, releases the fixture, and removes the finished product.
