Description

Technical Field

[0001] This application relates to the field of hardware processing technology, and more specifically, to a hardware processing buffer fixing device. Background Technology

[0002] In the field of hardware processing, securing hardware components is a crucial step in ensuring processing accuracy and operational safety. Traditional hardware processing securing devices generally employ rigid clamping methods, which involve directly applying clamping force to the hardware component using rigid fixtures to achieve positioning. While this rigid clamping method can meet basic securing requirements to a certain extent, it has significant limitations. Due to the lack of an effective buffer structure between the fixture and the hardware component, the clamping force acts directly on the surface of the hardware component. When the clamping force is excessive, it can easily lead to damage such as deformation, scratches, and indentations on the hardware component. Utility Model Content

[0003] To overcome the above deficiencies, this application provides a hardware processing buffer fixing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] A hardware processing buffer fixing device includes a base and a T-shaped frame integrally formed on the surface of the base. The device is characterized in that: a double-headed telescopic cylinder is installed inside the top of the T-shaped frame through a fixing column I, and two clamping arms are hinged to both sides through two fixing columns II. The two telescopic ends of the double-headed telescopic cylinder are respectively hinged to the outer ends of the two clamping arms through two hinge components. Two clamping components are respectively assembled on the inner ends of the two clamping arms. Two buffer components are respectively provided on the outer walls of the two clamping components. The two buffer components are respectively in contact with the inner surfaces of the two clamping arms.

[0006] Furthermore, the fixing post I and the two fixing posts II pass through the through holes on the outer walls of the double-headed telescopic cylinder and the two clamping arms, respectively, and their outer tops extend out of the surface of the T-shaped frame, and limit pins are inserted into them respectively.

[0007] Furthermore, the inner end of the clamping arm is hammer-shaped, and a through hole is provided on the side wall, through which the clamping assembly is installed.

[0008] Furthermore, the hinge assembly consists of a hinge block, a cylinder, and two fixing rings. The outer wall of the hinge block is welded to one telescopic end of the double-headed telescopic cylinder, and the clamping arm is provided inside. The cylinder is hinged to the inner wall of the hinge block and the clamping arm. The two fixing rings are fixedly connected to both ends of the cylinder, and their inner surfaces are in contact with the surface of the hinge block.

[0009] Furthermore, the clamping assembly consists of a connecting column, a clamping block, and two locking nuts. The buffer assembly is sleeved on the outer wall of the connecting column and inserted into the through hole. The inner surface of the clamping block is integrally formed with one end of the connecting column. The inner rings of the two locking nuts are fixedly connected to the external threads on the other end of the connecting column.

[0010] Furthermore, the buffer assembly consists of a sleeve and a mold spring. The inner ring of the sleeve and the mold spring are sleeved with the outer wall of the connecting column. The sleeve is sleeved on the outer ring of the mold spring, and one end is glued to the outer wall of the clamping arm, while the other end is spaced from the inner surface of the clamping block. The two ends of the mold spring are respectively attached to the opposite ends of the clamping arm and the clamping block.

[0011] Furthermore, the clamping end of the clamping block is integrally formed with a rubber pad, and the surface of the rubber pad is provided with raised points.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the coordinated design of the clamping component and the buffer component, allows the mold spring in the buffer component to elastically buffer the instantaneous force during the clamping process. Combined with the sleeve to stabilize and limit the spring, it avoids deformation of the hardware caused by rigid clamping. At the same time, the rubber pad and surface protrusions at the clamping end of the clamping block can increase the frictional contact area with the hardware and absorb the vibration and impact generated during processing through the deformation of the rubber pad. This effectively solves the problem of scratches and indentations on hardware caused by traditional rigid clamping and significantly improves the pass rate of hardware processing.

[0014] 2. The double-headed telescopic cylinder of this utility model drives the clamping arms to open and close synchronously through the hinge assembly. The cooperation between the hinge block and the cylinder ensures stable power transmission and avoids clamping arm deviation. Fixed column I and fixed column II are locked by limit pins to prevent the double-headed telescopic cylinder and clamping arms from becoming loose when subjected to force. Combined with the fastening of the connecting column by the locking nut in the clamping assembly, the hardware parts always maintain accurate positioning during processing, avoid displacement caused by external force, and ensure the accuracy requirements of milling, stamping and other processing procedures.

[0015] 3. The symmetrical telescopic design of the double-headed telescopic cylinder of this utility model ensures that the two clamping arms are subjected to force evenly, avoiding deformation of the components caused by excessive force on one side; the cooperation between the mold spring and the sleeve in the buffer assembly can disperse the reaction force on the clamping block and reduce the wear of the clamping arms and clamping components; the elastic contact method of the rubber pad protects the surface of the hardware and avoids the wear caused by direct force on the clamping block, thus extending the service life of the core components of the device and reducing the investment cost of production equipment.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0025] Example:

[0026] Please see Figure 1 , Figure 2 , Figure 4 A hardware processing buffer fixing device includes a base 1 and a T-shaped frame 2 integrally formed on the surface of the base 1.

[0027] The base 1 is made of high-strength cast iron and has a rectangular structure. Mounting holes are provided at the bottom to enhance the stability of the device during processing. A T-shaped frame 2 is formed on the upper surface of the base 1 using an integral casting process. The horizontal portion of the T-shaped frame 2 is completely flush with the surface of the base 1, while the vertical portion extends upwards, providing stable support for the core components of the entire device.

[0028] The T-shaped frame 2 has matching grooves at its top and both ends. The double-headed telescopic cylinder 4 and the two clamping arms 6 are respectively embedded in the corresponding grooves, and are precisely positioned and securely fixed by fixing posts I 3 and II 5. The grooves provide fitting installation space for each component, enhancing the compactness of the structure, and also provide lateral restraint for the double-headed telescopic cylinder 4 and clamping arms 6 during operation, reducing swaying under stress and further improving overall stability.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A hardware processing buffer fixing device includes a T-shaped frame 2 with a double-headed telescopic cylinder 4 installed inside the top via a fixing post I3, and two clamping arms 6 hinged to both sides via two fixing posts II5. The two telescopic ends of the double-headed telescopic cylinder 4 are respectively hinged to the outer ends of the two clamping arms 6 via two hinge components 7. The inner ends of the two clamping arms 6 are respectively equipped with two clamping components 8, and the outer walls of the two clamping components 8 are respectively provided with two buffer components 9, which are respectively in contact with the inner surfaces of the two clamping arms 6. Limit pins 10 are inserted into the top of the fixing post I3 and the two fixing posts II5. The inner ends of the clamping arms 6 are hammer-shaped, and the side walls are provided with through holes 61. The hinge component 7 consists of a hinge block 71, a cylinder 72, and two fixing rings 73. The clamping component 8 consists of a connecting post 81, a clamping block 82, and two locking nuts 83. The buffer component 9 consists of a sleeve 91 and a mold spring 92. The clamping end of the clamping block 82 is integrally made with a rubber pad 11.

[0030] The fixed column I3 and the top-inserted limiting pin 10 form a cooperative fixing structure: the fixed column I3 vertically penetrates the through hole of the T-shaped frame 2 and the double-headed telescopic cylinder 4 to build a basic positioning frame; the limiting pin 10 is tightly inserted into the reserved hole at the top of the fixed column I3, and locks the position of the fixed column I3 through axial limiting action. The two work together to firmly constrain the double-headed telescopic cylinder 4 in the groove at the top of the T-shaped frame 2, which not only ensures the verticality and positional accuracy of the double-headed telescopic cylinder 4 installation, but also resists the axial force and vibration generated during its operation, and avoids loosening or displacement.

[0031] The double-headed telescopic cylinder 4 serves as the core driving component. Through the synchronous extension and retraction of its two ends, it transmits driving force to the two clamping arms 6 via the hinge assembly 7, causing the two clamping arms 6 to open and close synchronously around the fixed column II 5. During this process, the two clamping components 8, assembled at the inner ends of the clamping arms 6, move synchronously with the clamping arms 6, ultimately cooperating to precisely clamp the hardware parts, ensuring the coordination and stability of the clamping action, and providing a reliable positioning basis for subsequent processing.

[0032] The fixed post II5 and the top-inserted limiting pin 10 form a cooperative fixing structure: the fixed post II5 is perpendicularly inserted through the through holes at both ends of the T-shaped frame 2 and the clamping arm 6, forming a radial positioning reference; the limiting pin 10 is tightly inserted into the top hole of the fixed post II5, and restricts the displacement of the fixed post II5 by axial locking. The two work together to firmly constrain the clamping arm 6 in the grooves at both ends of the T-shaped frame 2. This structure not only ensures the axial accuracy of the clamping arm 6 when rotating around the fixed post II5, but also resists the radial force and torque generated during the clamping process, preventing the clamping arm 6 from loosening or swaying, and providing solid support for the smoothness of the clamping action.

[0033] The inner end of the clamping arm 6 adopts a hammer-shaped structure design, which was optimized through mechanical analysis. The end of the hammer-shaped structure has a large force-bearing area, which can better disperse the stress generated during clamping and prevent the inner end of the clamping arm 6 from deforming or breaking due to long-term stress. At the same time, the through hole 61 provides sufficient space for the installation of the clamping component 8.

[0034] The hinge assembly 7 is the core transmission component connecting the double-headed telescopic cylinder 4 and the clamping arm 6. The closed end of its U-shaped hinge block 71 is seamlessly welded to the telescopic end of the double-headed telescopic cylinder 4. The weld seam is precision ground to form a smooth transition, ensuring lossless power transmission. Inside the open end of the hinge block 71, a cylinder 72 passes through corresponding holes on the outer wall of the hinge block 71 and the outer end of the clamping arm 6, hinged together to allow the clamping arm 6 to rotate flexibly around the cylinder 72. Simultaneously, two fixing rings 73 are fixedly connected to both ends of the cylinder 72, their inner sides tightly fitting against the outer wall of the hinge block 71 to form an axial locking structure. This securely confines the cylinder 72 to the hinged position, preventing axial movement during rotation under force, thus ensuring the stability and reliability of the power transmission of the entire hinge assembly 7.

[0035] The clamping assembly 8 is the core clamping component that directly acts on the hardware parts, providing stable positioning during the hardware processing. The connecting post 81 and the through hole 61 at the inner end of the clamping arm 6 are precisely fitted together. Through the tight fit between the post and hole, the clamping block 82 is stably assembled on the clamping end of the clamping arm 6, ensuring accurate relative positioning between the clamping block 82 and the clamping arm 6. Simultaneously, two locking nuts 83 form a threaded connection with the external thread at the outer end of the connecting post 81. Tightening these nuts effectively restricts the axial movement and radial displacement of the connecting post 81 within the through hole 61, further ensuring the overall stability of the clamping assembly 8 and laying the foundation for reliable clamping of the hardware parts.

[0036] Among them, the buffer component 9 is the core structure for achieving flexible buffering during the clamping process, providing elastic buffering capability for the clamping component 8 and avoiding hard damage to the hardware. Specifically, a sleeve 91 and a mold spring 92 are coaxially sleeved on the outer wall of the connecting column 81, forming a synergistic buffering mechanism: the mold spring 92, with its excellent elastic deformation characteristics, provides a controllable buffering clamping force for the clamping block 82. When the hardware is not clamped, the mold spring 92 is in a naturally released state, with its two ends tightly fitted to the inner surface of the clamping block 82 and the inner wall of the clamping arm 6, respectively, maintaining the initial pre-tightened posture; when the hardware is clamped, the clamping block 82 is pushed by the reaction force of the hardware, causing the connecting column 81 to slide slightly outward along the through hole 61. At this time, the mold spring 92 is compressed and accumulates elastic potential energy, forming a buffering clamping effect through the reverse elastic force. Meanwhile, the sleeve 91, as a rigid protective structure, has its inner wall in contact with the outer ring of the mold spring 92. This not only guides the spring to compress axially to avoid lateral bending, but also provides rigid support when the spring is compressed to its limit, effectively preventing the mold spring 92 from fatigue damage due to excessive compression and ensuring the long-term stability of the buffer function.

[0037] The rubber pad 11 and the buffer assembly 9 form a dual buffering mechanism, which further optimizes the flexible fixing effect of the hardware through synergy. The rubber pad 11 at the clamping end of the clamping block 82, with its own elastic deformation characteristics, directly contacts the surface of the hardware, which can absorb the instantaneous impact force at the beginning of clamping, and at the same time enhance the friction through the surface protrusions to prevent slippage; while the mold spring 92 in the buffer assembly 9 provides continuous buffering clamping force through elastic extension and contraction. The two form a progressive buffer from the contact level and the force transmission level, which not only avoids damage to the surface of the hardware by rigid clamping, but also offsets the vibration and impact during the processing through dual elastic feedback, significantly improving the stability and safety of the hardware clamping.

[0038] It should be noted that the specific models and specifications of the double-headed telescopic cylinder 4 and the mold spring 82 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0039] The power supply and principle of the double-headed telescopic cylinder 4 are clear to those skilled in the art, and will not be described in detail here.

[0040] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
