Description

Technical Field

[0001] This utility model relates to the field of hydraulic caliper manufacturing technology, specifically to a special mold base for hydraulic caliper jaw plates. Background Technology

[0002] In the production of hydraulic calipers, the jaw plate is a key component, and its machining accuracy directly affects the overall performance of the caliper. Traditional hydraulic caliper jaw plate machining molds have many problems and cannot meet the demands of modern high-precision machining. For example, in terms of positioning, most molds cannot accurately position the jaw plate, causing it to easily shift during machining. This results in significant dimensional deviations in the machined jaw plate, affecting product quality and assembly accuracy. Furthermore, existing molds lack structural stability, making them prone to loosening and deformation when subjected to external impacts during machining. This further reduces machining accuracy and may even lead to equipment failure, impacting production efficiency.

[0003] Meanwhile, traditional mold bases are cumbersome to operate when loading and unloading the jaw plate, requiring a lot of time and manpower, which increases production costs. In addition, frequent loading and unloading may also damage the jaw plate and mold base, shortening their service life.

[0004] Therefore, a new type of dedicated die holder for hydraulic caliper jaws urgently needs to be developed. Utility Model Content

[0005] The purpose of this utility model is to provide a special mold base for hydraulic caliper jaw plates, which aims to solve the problems of inaccurate positioning, unstable structure and inconvenient loading and unloading of traditional mold bases, thereby improving the processing accuracy and production efficiency of hydraulic caliper jaw plates and reducing production costs.

[0006] To achieve the above objectives, the following technical solution is provided:

[0007] A special mold base for hydraulic caliper jaw plates includes a base, a support seat fixedly connected to the top of the base, a positioning groove adapted to the hydraulic caliper jaw plate on the top of the support seat, and an anti-slip texture on the inner wall of the positioning groove. Mounting blocks are fixedly connected to the top of the support seat and on both sides of the positioning groove. A fastening screw is threaded to the top of each mounting block, and a pressure block is rotatably connected to the bottom of the fastening screw through a bearing. A rubber buffer pad is fixedly connected to the bottom of the pressure block, and the bottom of the rubber buffer pad contacts the top of the hydraulic caliper jaw plate. An annular guide rail is fixedly connected to the top of the base and on the outer side of the support seat. A moving block is slidably connected to the top of the annular guide rail, a connecting rod is fixedly connected to the top of the moving block, and a fixing clamp is fixedly connected to the top of the connecting rod.

[0008] Preferably, the inner wall of the positioning groove is provided with a positioning protrusion, and the bottom of the hydraulic caliper jaw plate is provided with a positioning groove that cooperates with the positioning protrusion.

[0009] Preferably, a rotating handle is fixedly connected to the top of the fastening screw, and the surface of the rotating handle is provided with anti-slip texture.

[0010] Preferably, the number of moving blocks is four, and they are evenly distributed on the top of the annular guide rail.

[0011] Preferably, there are two fixing hoops, which are symmetrically distributed on both sides of the support base.

[0012] Preferably, the support base is made of high-strength alloy steel.

[0013] Preferably, the inner wall of the fixing hoop is fixedly connected with an anti-slip pad, and the inner wall of the anti-slip pad is in contact with the surface of the support base.

[0014] Preferably, a shock-absorbing pad is fixedly connected to the bottom of the base, and the bottom of the shock-absorbing pad is provided with anti-slip ridges. The shock-absorbing pad is made of rubber.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Precise positioning: Through the cooperation of positioning grooves, anti-slip textures, positioning protrusions and positioning recesses, high-precision positioning of the hydraulic caliper jaw plate can be achieved, effectively reducing the displacement of the jaw plate during the processing, improving processing accuracy, and ensuring that the processed jaw plate is dimensionally accurate and of reliable quality.

[0017] Stable structure: The support base is made of high-strength alloy steel and wear-resistant treatment. Combined with four moving blocks evenly distributed on the ring guide rail and two symmetrically distributed fixing hoops, it can provide stable support for the support base from multiple directions, which greatly improves the overall structural stability of the mold base.

[0018] When subjected to external impacts during processing, it can effectively prevent the mold base from loosening or deforming, ensuring the smooth progress of the processing and improving production efficiency.

[0019] Easy to load and unload: The rotating handle allows operators to easily and quickly rotate the fastening screw to fix and loosen the toothed plate; at the same time, the overall mold base has a reasonable structural design, and the connection and disassembly between the components are convenient, which greatly saves the time and manpower required to load and unload the toothed plate, reduces production costs, and reduces damage to the toothed plate and mold base during loading and unloading, thus extending their service life.

[0020] Shock absorption and anti-slip: The rubber shock-absorbing pads at the bottom of the base can effectively reduce processing vibration and improve processing accuracy, while the anti-slip ridges at the bottom of the shock-absorbing pads ensure the stability of the mold base and prevent displacement during operation, further improving the working reliability of the mold base.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1-2As shown, a special mold base for hydraulic caliper jaw plates mainly includes a base 1. The base 1 serves as the basic support structure for the entire mold base, providing an installation and load-bearing platform for other components. A support seat 2 is securely fixed to the top of the base 1. The support seat 2 is a key component for placing and positioning the hydraulic caliper jaw plate, and its top has a positioning groove 3 that precisely matches the shape and size of the hydraulic caliper jaw plate. The design of the positioning groove 3 enables the jaw plate to achieve accurate initial positioning during placement, reducing deviations. The inner wall of the positioning groove 3 is provided with anti-slip texture 4. This design greatly increases the friction between the jaw plate and the positioning groove 3, preventing the jaw plate from sliding due to external forces during processing, further improving positioning stability.

[0028] Mounting blocks 5 are fixedly connected to the top of the support base 2, on both sides of the positioning groove 3. Mounting blocks 5 are used to mount fastening screws 6, with the top of the screws 6 passing through the mounting blocks 5 and extending upwards. A threaded hole is provided at the top of the mounting block 5 to match the external thread of the fastening screw 6, achieving a threaded connection. This connection method allows the fastening screw 6 to rotate smoothly within the mounting block 5 while ensuring sufficient tightening force. The bottom of the fastening screw 6 extends to the bottom of the mounting block 5 and is rotatably connected to a pressure block 7 via a bearing. The bearing ensures that the pressure block 7 remains relatively stable when the fastening screw 6 rotates, preventing it from rotating with the screw and ensuring that the pressure block 7 can smoothly apply pressure to the toothed plate. A rubber buffer pad 8 is fixedly connected to the bottom of the pressure block 7, providing good elasticity and cushioning performance. When the pressure block 7 moves downward under the drive of the fastening screw 6 and contacts the top of the hydraulic caliper jaw plate, the rubber buffer pad 8 can prevent the pressure block 7 from causing hard damage to the surface of the jaw plate, while further enhancing the fixing effect on the jaw plate and preventing the jaw plate from shaking during processing.

[0029] An annular guide rail 9 is fixedly connected to the top of the base 1, located outside the support 2. The annular guide rail 9 provides a sliding track for the movable blocks 10, allowing them to move along a specific trajectory. There are four movable blocks 10, evenly distributed on the top of the annular guide rail 9. This even distribution design allows for fixation of the support 2 from multiple directions, improving the overall stability of the mold base. A connecting rod 11 is fixedly connected to the top of each movable block 10, serving to connect the movable block 10 to the fixing clamp 12. Two fixing clamps 12 are fixedly connected to the top of the connecting rod 11, symmetrically distributed on both sides of the support 2. Anti-slip pads are fixedly connected to the inner walls of the fixing clamps 12, with the inner walls of the anti-slip pads in close contact with the surface of the support 2. The anti-slip pad increases the friction between the fixing hoop 12 and the support base 2, preventing the fixing hoop 12 from sliding on the surface of the support base 2, further improving the fixing effect on the support base 2, and ensuring the stability of the entire mold base during the processing.

[0030] Furthermore, the inner wall of the positioning groove 3 is provided with a positioning protrusion 16, and correspondingly, the bottom of the hydraulic caliper jaw plate is provided with a positioning groove 15 that precisely matches the positioning protrusion 16. The cooperation between the positioning protrusion 16 and the positioning groove 15 forms a high-precision positioning structure, which can further improve the positioning accuracy of the hydraulic caliper jaw plate, effectively prevent the jaw plate from shifting during processing, and ensure processing accuracy.

[0031] To facilitate the operation of the fastening screw 6, a rotating handle is fixedly connected to the top of the fastening screw 6. The surface of the rotating handle is provided with anti-slip texture. This design increases the friction between the operator's hand and the rotating handle, making it easier and more stable for the operator to turn the rotating handle. It also facilitates precise control of the rotation angle and tightening force of the fastening screw 6, thereby achieving a firm fixation and convenient loosening of the jaw plate.

[0032] Support base 2 is made of high-strength alloy steel, which has excellent strength and wear resistance. The surface of support base 2 has undergone wear-resistant treatment, further improving its surface hardness and wear resistance, effectively resisting wear during processing, extending the service life of support base 2, and ensuring the long-term stable operation of the mold base.

[0033] A shock-absorbing pad made of rubber is fixedly connected to the bottom of base 1. The rubber shock-absorbing pad has excellent shock absorption and cushioning properties, effectively reducing the transmission of vibrations generated during processing to base 1 and other equipment, thus minimizing the impact of vibration on processing accuracy. The bottom of the shock-absorbing pad has anti-slip textured surfaces. These textures increase the friction between the shock-absorbing pad and the placement surface, preventing displacement of the mold base during operation and improving the placement stability of the mold base.

[0034] Working principle of this utility model device:

[0035] When using this hydraulic caliper jaw plate holder, first place the base 1 on a stable workbench. Due to the anti-slip texture on the bottom of the shock-absorbing pad, the base 1 can be placed stably on the workbench without displacement. Then, place the hydraulic caliper jaw plate into the positioning groove 3 on the top of the support base 2, so that the positioning groove 15 on the bottom of the jaw plate is precisely aligned with the positioning protrusion 16 on the inner wall of the positioning groove 3. Through this engagement, the jaw plate achieves initial precise positioning. At the same time, the anti-slip texture 4 on the inner wall of the positioning groove 3 increases the friction between the jaw plate and the positioning groove 3, further preventing the jaw plate from sliding during placement.

[0036] Next, the operator rotates the handle, causing the fastening screw 6 to rotate within the mounting block 5. Due to the threaded connection between the fastening screw 6 and the mounting block 5, rotating the handle causes the fastening screw 6 to gradually move downwards. As the fastening screw 6 moves downwards, the rubber buffer pad 8 at the bottom of the pressure block 7 gradually contacts the top of the toothed plate, applying pressure to the toothed plate. The elasticity of the rubber buffer pad 8 prevents the pressure block 7 from damaging the surface of the toothed plate, while ensuring that the toothed plate is firmly fixed within the positioning groove 3, preventing wobbling during processing.

[0037] After the initial fixing of the toothed plate is completed, it is necessary to further improve the overall stability of the mold base. At this time, the sliding block 10, due to the sliding fit between the sliding block 10 and the annular guide rail 9, can move along the trajectory of the annular guide rail 9. The connecting rod 11 at the top of the sliding block 10 moves with the sliding block 10, thereby driving the fixing clamps 12 to move. The two fixing clamps 12 are moved to both sides of the support base 2, so that the anti-slip pads on the inner walls of the fixing clamps 12 are in close contact with the surface of the support base 2. The anti-slip pads increase the friction between the fixing clamps 12 and the support base 2, thereby fixing the support base 2 from both sides and further enhancing the stability of the mold base.

[0038] After processing, when it is necessary to disassemble the toothed plate, the operator rotates the handle in the opposite direction to move the fastening screw 6 upward, causing the pressure block 7 and the rubber buffer pad 8 to gradually move away from the toothed plate, thus releasing the fixation of the toothed plate. Then, the moving block 10 is slid along the annular guide rail 9 to move the fixing clamp 12 away from the support seat 2. At this point, the toothed plate can be easily removed from the positioning groove 3, completing the toothed plate disassembly process.

[0039] Example 1: Die base suitable for machining small hydraulic caliper jaw plates

[0040] The hydraulic caliper jaw plate mold base of this embodiment has a relatively small overall size to accommodate the processing requirements of small hydraulic caliper jaw plates. The base 1 is made of cast iron, providing stable support for the entire mold base. The support base 2 is also made of high-strength alloy steel, and the positioning groove 3 on the top is sized to match the small hydraulic caliper jaw plate. The anti-slip texture 4 on the inner wall of the positioning groove 3 uses a fine mesh design to further enhance friction with the jaw plate.

[0041] Mounting block 5 is fixedly connected to the top of support base 2 and located on both sides of positioning groove 3. The anti-slip texture on the rotating handle surface of the top of fastening screw 6 is a uniformly spaced strip pattern. Pressure block 7 adopts a cuboid structure, and the rubber buffer pad 8 at the bottom is made of nitrile rubber, which has good elasticity and wear resistance.

[0042] There are four movable blocks 10 on the annular guide rail 9. The connecting rod 11 is made of stainless steel, and its top fixing hoop 12 is semi-circular, with its inner diameter matching the outer diameter of the support base 2. The inner wall of the fixing hoop 12 is fixedly connected with a rubber anti-slip pad. The shock-absorbing pad at the bottom of the base 1 is made of natural rubber, and the anti-slip ridges at the bottom are strip-shaped protrusions.

[0043] In practical applications, the mold base of this embodiment can accurately position the small hydraulic caliper jaw plate. Through the synergistic effect of various components, it ensures the stability of the processing process and improves the processing accuracy and production efficiency of the small jaw plate.

[0044] Example 2: Die base suitable for machining large hydraulic caliper jaw plates

[0045] The hydraulic caliper jaw plate mold base in this embodiment has a large overall size to meet the processing requirements of large hydraulic caliper jaw plates. The base 1 is made of cast steel, providing sufficient load-bearing capacity. The support base 2 is made of high-strength alloy steel and undergoes a special heat treatment process. The positioning groove 3 on the top precisely matches the dimensions of the large hydraulic caliper jaw plate. The anti-slip texture 4 on the inner wall of the positioning groove 3 is coarsely serrated, increasing friction with the large jaw plate and preventing slippage.

[0046] Mounting block 5 is fixed to the top of support base 2 and located on both sides of positioning groove 3. The anti-slip texture of the rotating handle at the top of fastening screw 6 is a diamond grid pattern, making it easy for the operator to rotate. Pressure block 7 has a cuboid structure, and the rubber buffer pad 8 at the bottom is made of fluororubber, which has the characteristics of high temperature resistance and wear resistance.

[0047] There are four moving blocks 10 on the annular guide rail 9. The connecting rod 11 is made of high-strength alloy steel pipe, and the top fixing hoop 12 is semi-circular, with its inner diameter matching the outer diameter of the support base 2. The anti-slip pad on the inner wall of the fixing hoop 12 is made of silicone, providing good anti-slip performance. The shock-absorbing pad at the bottom of the base 1 is made of butyl rubber, and the anti-slip ridges on the bottom are block-shaped protrusions to enhance friction with the workbench surface.

[0048] The mold base in this embodiment can stably support and position large hydraulic caliper jaw plates, withstand large external impacts during processing, ensure the processing accuracy of large jaw plates, improve production efficiency, and meet the processing requirements of large hydraulic caliper jaw plates.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
