Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping equipment technology, and in particular to a stable fixing device for processing spotted copper workpieces. Background Technology

[0002] Bronze is a precious metal craft material, and its processing, such as carving, grinding, and polishing, requires extremely high stability of the workpiece. Any slight wobbling or inaccurate positioning can lead to processing failure and damage to valuable workpieces.

[0003] In current processing practices, the fixing devices used are often relatively simple in structure. For example, some devices use single-sided drive or manual locking for clamping. This method can easily lead to uneven clamping force on both sides or asynchronous clamping processes, causing the copper workpiece to slightly shift after being subjected to force, deviating from the preset processing center line, thus affecting the processing accuracy.

[0004] More importantly, clamping stability is not only reflected in static fixation but also in the dynamic machining process. High-frequency vibrations are generated when the machining tool contacts the workpiece. If these vibrations are not effectively absorbed and isolated, they will be transmitted to the entire clamping device and even the workpiece itself, causing resonance or vibration, severely affecting the surface finish and machining accuracy. Many existing clamping devices neglect consideration of dynamic stability during machining and lack specialized vibration damping designs, making it difficult to guarantee machining quality.

[0005] Therefore, this utility model proposes a stable fixing device for processing spotted copper workpieces to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a stable fixing device for processing spotted copper workpieces, aiming to improve the existing technology where the clamping process of fixing devices for processing spotted copper workpieces is prone to inaccurate workpiece positioning and lacks a shock-absorbing structure, thus affecting processing stability.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a stabilizing and fixing device for processing spotted copper workpieces, comprising a base, a main body shell, and a worktable fixed to the upper part of the main body shell; the main body shell is mounted on the base in a way that allows it to move up and down via a shock-absorbing component; and a clamping component;

[0008] The core of the clamping assembly lies in its precise linkage mechanism, which includes fixed blocks symmetrically arranged on both sides of the worktable and fixedly connected to the main body shell, a first rotating column rotatably connected to the fixed block, clamping arms on both sides, clamping plates fixedly connected to the other end of the clamping arms, a first connecting block, a second connecting block, a third connecting block on both sides, and a fourth rotating column, a cylinder, a support column, a moving plate, and a first moving column for driving.

[0009] Furthermore, the end of the clamping arm is rotatably connected to the first rotating column, and the middle is rotatably connected to the second rotating column; the ends of the first connecting blocks are respectively rotatably connected to the corresponding second rotating columns; the ends of the second and third connecting blocks are rotatably connected to the fourth rotating column; the other ends of the first connecting blocks on both sides are respectively rotatably connected to the other ends of the second and third connecting blocks through the third rotating column; the cylinder drives the fourth rotating column to move up and down through the support column, the moving plate and the first moving column, thereby achieving synchronous centering and clamping of the clamping plates on both sides through the synergistic action of the above linkage mechanism;

[0011] Preferably, the shock absorption assembly further includes a limiting ring; the limiting ring is fixedly connected to the second moving column and slidably fitted to the inner wall of the base; this structure not only enhances the stability of the movement of the second moving column, but also limits the upward displacement of the main body shell to prevent it from falling out, thus improving the safety of the device.

[0012] Preferably, there are multiple second movable columns, which are arranged in an array on the bottom wall outside the main body. This multi-point support shock absorption structure makes the support more stable and the shock absorption effect more uniform.

[0013] Preferably, the inner bottom surface of the base is provided with an annular groove for positioning the bottom of the spring. This design can effectively prevent the spring from shifting laterally during compression, ensuring the reliability of the shock absorption assembly.

[0014] Preferably, in order to achieve precise synchronous clamping, the fixing block, the clamping arm, and the first connecting block are all symmetrically arranged with the vertical plane passing through the center of the fourth rotating column as the plane of symmetry;

[0015] Preferably, to optimize the structural layout, the second connecting block and the third connecting block are arranged side by side along the axial direction of the fourth rotating column, making the structure more compact;

[0016] Preferably, the cylinder, the support column, the movable plate, and the first movable column are all housed inside the main body shell, which not only makes the appearance neat but also provides effective protection for the drive components.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-5 The present invention provides an embodiment of a stable fixing device for processing spotted copper workpieces, comprising a base 403, a main body shell 2, and a shock-absorbing component 4; the main body shell 2 is movably mounted on the base 403 via the shock-absorbing component 4, and the base 403 provides a stable mounting foundation for the entire device; a worktable 5 is fixedly connected to the upper part of the main body shell 2, and the worktable 5 is used to support the spotted copper workpiece 1.

[0030] Clamping assembly 3 is installed on the main body shell 2 and acts above the worktable 5 to clamp the copper workpiece 1; shock absorption assembly 4 is connected between the main body shell 2 and the base 403 to absorb and buffer the vibration generated during processing and improve the overall stability of the device.

[0031] The clamping assembly 3 includes a fixing block 303, which is symmetrically arranged on both sides of the worktable 5 and fixedly connected to the main body shell 2, serving as the fixing base point of the clamping mechanism; a first rotating column 304 is rotatably connected inside the fixing block 303.

[0032] The ends of the clamping arms 302 on both sides are rotatably connected to the corresponding first rotating column 304, so that the clamping arms 302 can rotate around the axis of the first rotating column 304. The other end of the clamping arms 302 is fixedly connected to the clamping plate 301, which is used to directly contact the spotted copper workpiece 1 to achieve clamping.

[0033] The middle part of the clamping arm 302 is rotatably connected to the second rotating column 306; the ends of the first connecting blocks 305 on both sides are rotatably connected to the corresponding second rotating column 306, forming the core linkage transmission structure.

[0034] The clamping assembly 3 also includes a second connecting block 308 and a third connecting block 310. The ends of the second connecting block 308 and the third connecting block 310 are rotatably connected to a fourth rotating column 309. To achieve a compact structure, the second connecting block 308 and the third connecting block 310 are arranged side by side along the axial direction of the fourth rotating column 309. The other ends of the first connecting blocks 305 on both sides are rotatably connected to the other ends of the second connecting block 308 and the third connecting block 310 respectively through the third rotating column 307.

[0035] To drive the clamping assembly 3 to move, the device is equipped with a cylinder 312, which is vertically installed inside the main body shell 2 to provide linear driving force. The cylinder 312 drives the bottom end of the support column 313 to move up and down. The moving plate 314 is fixedly connected to the top end of the support column 313. The bottom end of the first moving column 311 is fixedly connected to the moving plate 314, and its top end abuts against the fourth rotating column 309 to transmit the driving force to the linkage mechanism.

[0036] To ensure the synchronicity and stability of the clamping process, the fixing block 303, clamping arm 302 and the first connecting block 305 are symmetrically arranged with the vertical plane passing through the center of the fourth rotating column 309 as the plane of symmetry, so as to ensure that the clamping plates 301 on both sides move synchronously towards the center and the clamping force is uniform.

[0037] To make the overall structure of the device neater and safer, the cylinder 312, support column 313, moving plate 314 and first moving column 311 are all housed inside the main body shell 2;

[0038] The shock absorption assembly 4 includes at least a second movable column 401 and a spring 404; the top end of the second movable column 401 is fixedly connected to the bottom wall of the main body shell 2, and its column body is slidably inserted through the base 403 to guide the main body shell 2 to perform stable vertical movement.

[0039] Spring 404 is sleeved on the outer periphery of the second moving column 401, and the two ends of spring 404 abut against the bottom wall of the main body shell 2 and the inner bottom surface of the base 403 respectively. As the main elastic element, spring 404 is used to support the weight of the main body shell 2 and all its components, and absorbs vibration energy through elastic deformation when subjected to impact.

[0040] Meanwhile, to enhance the stability and safety of the shock absorption assembly 4, the shock absorption assembly 4 also includes a limiting ring 402. The limiting ring 402 is fixedly connected to the second moving column 401 and slidably fitted to the inner wall of the base 403. This fit not only further ensures the verticality of the movement of the second moving column 401, but also allows the upper end face of the limiting ring 402 to fit with the top of the base 403 to limit the upward displacement of the main body shell 2 and prevent the main body shell 2 from detaching from the base 403 due to severe vibration.

[0041] This spring-sliding column damping structure, which consists of the second moving column 401, the spring 404 and the limiting ring 402, ensures that the main body shell 2 can smoothly perform buffering movement when subjected to processing vibrations, significantly improving the stability of the entire device in working condition.

[0042] In a preferred embodiment, in order to make the shock absorption effect more stable and the support force more uniform, there are multiple second moving columns 401, and the multiple second moving columns 401 are arranged in an array on the bottom wall of the main body shell 2; accordingly, each second moving column 401 is equipped with a spring 404 and a limiting ring 402, forming multiple parallel shock absorption units to jointly support the main body shell 2.

[0043] As another preferred embodiment, in order to ensure that the spring 404 is stable in position during operation and to prevent it from shifting laterally when compressed, the inner bottom surface of the base 403 is provided with an annular groove for positioning the bottom of the spring 404. The bottom end of the spring 404 is embedded in the annular groove, thereby achieving reliable positioning.

[0044] Working principle: When it is necessary to fix the spotted copper workpiece 1, place the spotted copper workpiece 1 in the center above the worktable 5, and then start the cylinder 312; the cylinder 312 pushes the support column 313 upward, and the support column 313 drives the moving plate 314 on its top and the first moving column 311 to move upward synchronously.

[0045] The top of the first moving column 311 pushes the fourth rotating column 309 upward. Since the fourth rotating column 309 is the common rotation center of the second connecting block 308 and the third connecting block 310, its upward movement will force the second connecting block 308 and the third connecting block 310 to rotate around the fourth rotating column 309 as the axis, and pull the first connecting blocks 305 on both sides inward through the third rotating column 307 at its other end.

[0046] The first connecting block 305 pulls the clamping arms 302 on both sides through the second rotating column 306, causing the clamping arms 302 to rotate inward synchronously around their respective fixed rotation centers, namely the first rotating column 304. As the clamping arms 302 rotate, the clamping plates 301 at their front ends clamp the spotted copper workpiece 1 synchronously and centeredly, ultimately achieving a firm and stable fixation. The entire linkage mechanism transforms the tiny linear displacement of the cylinder 312 into a huge, symmetrical clamping force.

[0047] During the processing of the spotted copper workpiece 1, the vibrations generated during the processing are first transmitted to the worktable 5 and the main body shell 2. Since the main body shell 2 is connected to the base 403 through the shock-absorbing component 4, the vibrations are transmitted downwards along the main body shell 2 and the second moving column 401, and act on the spring 404, causing the spring 404 to be compressed and rebound, thereby absorbing and buffering most of the vibration energy, effectively preventing the vibration from being directly transmitted to the ground or causing equipment resonance. During this process, the second moving column 401 slides smoothly within the base 403, and the limiting ring 402 ensures the stability and safety of the movement, ultimately guaranteeing the smoothness of the processing and the surface finish of the spotted copper workpiece 1.
