Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of clamping technology, and more specifically, to a pneumatic hydraulic vise. Background Technology

[0002] In the field of machining, workpiece clamping is a fundamental and crucial step in the machining process. Traditional mechanical vises mostly rely on a screw and nut mechanism, where the workpiece is clamped by manually rotating the screw to move the jaws. This method is cumbersome, requiring workers to expend a lot of physical strength and time to adjust the clamping degree. In mass production scenarios, frequent manual operation greatly reduces production efficiency. Moreover, the clamping force depends entirely on the worker's experience, making it difficult to guarantee consistency and accuracy. For some workpieces with complex shapes and special materials, it is difficult to achieve the ideal clamping effect, which can easily lead to displacement and deformation of the workpiece during processing, seriously affecting machining accuracy and product quality.

[0003] In addition, both traditional mechanical vises and early pneumatic and hydraulic vises have shortcomings in terms of installation adaptability. Most of them can only be adapted to specific types of workbenches and lack flexible installation and adjustment mechanisms, making it difficult to meet the diverse installation needs in different production environments. In the current context of increasingly popular multi-variety and small-batch production modes, this limitation seriously restricts the versatility of equipment and the flexibility of production. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a pneumatic hydraulic vise, which solves the technical problem that existing pneumatic and hydraulic vises are insufficient in terms of installation adaptability. Most of them can only be adapted to specific types of workbenches, lack flexible installation and adjustment mechanisms, and are difficult to meet the diverse installation needs in different production environments.

[0005] According to one aspect, at least one embodiment of this disclosure provides a pneumatic hydraulic vise, comprising: A clamp base, wherein a clamp is provided on the upper end face of the clamp base; A translation drive assembly is disposed on the clamp; A switching installation component is disposed at the bottom of the clamp; The translation drive assembly includes a drive cavity, which is located on the upper end face of the clamp seat. A force-bearing clamp is provided at one end of the clamp seat. A clamping clamp is provided on the drive cavity. A drive plate is provided at the bottom of the clamping clamp. A drive screw is provided inside the drive cavity. The drive screw is threadedly connected to the drive plate. A sliding track is provided on the inner side wall of the drive cavity. A drive bar is provided on the side wall of the drive plate. The drive bar is embedded inside the sliding track.

[0006] As a further technical solution, both the clamping clamp and the force clamp are provided with insertion slots, and clamping plates are inserted into the insertion slots. One end of the drive screw is provided with a drive shaft, and one end of the drive shaft extends out of the drive cavity.

[0007] As a further technical solution, the switching installation component includes a mounting slot, which is located at the bottom of the clamp seat. A switching port is provided on the side wall of the mounting slot. A rotating shaft is provided on the switching port. A rotating plate is provided on the rotating shaft. A bolt tightening hole is provided on the rotating plate. A mounting frame is provided on the side wall of the clamp seat. A power source mounting plate is provided at the end of the mounting frame.

[0008] As a further technical solution, one end of the mounting frame is provided with a plug-in shaft, and the plug-in shaft is plugged into and fixed to the power source mounting plate.

[0009] As a further technical solution, one end of the mounting frame is provided with a positioning insert shaft, which is inserted into the outer side wall of the clamp seat, and the side wall of the positioning insert shaft is provided with an anti-slip block.

[0010] As a further technical solution, the side wall of the clamp seat has a cleaning port, which is connected to the interior of the drive cavity.

[0011] As a further technical solution, each end of the clamp seat is provided with a drive port, and a connecting bearing is provided inside the drive port. The drive screw is movably connected to the connecting bearing.

[0012] As a further technical solution, the clamping plate is provided with a locking bolt, and the force-bearing clamp and the clamping clamp are positioned correspondingly.

[0013] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the hydraulic cylinder transmits pressure through hydraulic oil. The incompressibility of the hydraulic system makes the output clamping force more stable, eliminating the "force decay" problem caused by gas compression. By adjusting the hydraulic cylinder pressure, the clamping force is precisely controlled, avoiding both insufficient clamping force leading to workpiece displacement and overpressure causing workpiece deformation. It is especially suitable for scenarios with stringent requirements for machining accuracy, such as precision molds. The precision threaded fit between the drive screw and the drive plate, and the guide limit of the drive bar and the sliding rail, ensure consistent fit between the clamping plate and the workpiece, further reducing machining errors caused by clamping deviations and improving product qualification rate.

[0016] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0021] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] like Figures 1-3 As shown, it illustrates a pneumatic hydraulic vise of the present disclosure, characterized in that it comprises: Clamp base 1, with clamps 2 provided on the upper end face of clamp base 1; Translation drive assembly 3 is mounted on clamp 1; Switch to installation component 4, which is located at the bottom of clamp 1; The translation drive assembly 3 includes a drive cavity 3-1, which is located on the upper surface of the clamp seat 1. A force-bearing clamp 3-2 is provided at one end of the clamp seat 1. A clamping clamp 3-3 is provided on the drive cavity 3-1. A drive plate 3-4 is provided at the bottom of the clamping clamp 3-3. A drive screw 3-5 is provided inside the drive cavity 3-1. The drive screw 3-5 is threadedly connected to the drive plate 3-4. A sliding rail 3-6 is provided on the inner side wall of the drive cavity 3-1. A drive bar 3-7 is provided on the side wall of the drive plate 3-4. The drive bar 3-7 is embedded inside the sliding rail 3-6.

[0023] The switching installation component 4 includes a mounting slot 4-1, which is located at the bottom of the clamp seat 1. The side wall of the mounting slot 4-1 has a switching port 4-2, a rotating shaft 4-3 is provided on the switching port 4-2, a rotating plate 4-4 is provided on the rotating shaft 4-3, and a bolt tightening hole 4-5 is provided on the rotating plate 4-4. The side wall of the clamp seat 1 has a mounting frame 4-6, and the end of the mounting frame 4-6 has a power source mounting plate 4-7.

[0024] In some examples, the vise serves as the connection reference between the vise and the workbench. By engaging with the workbench slot, it restricts the horizontal displacement of the vise, ensuring installation and positioning accuracy. The rotating plate 4-4 can rotate around the spin axis 4-3. By adjusting the position of the bolt tightening hole 4-5, it can adapt to workbench mounting holes with different spacing, improving the vise's versatility. At the same time, it acts as an "adapter" for angle adjustment when fine-tuning the vise angle. The spin axis 4-3 provides rotational support for the rotating plate 4-4, ensuring smooth rotation of the rotating plate 4-4 and realizing the angle fine-tuning function. The bolt tightening hole 4-5 allows the fixing bolt to pass through, locking the rotating plate 4-4 to the workbench, thereby fixing the vise. It is a key hole for transmitting locking force.

[0025] Choose the appropriate installation method according to the installation conditions on the workbench. If the workbench has a standard mounting slot 4-1, align the mounting slot 4-1 at the bottom of the vise seat 1 with the slot (use the positioning function of the mounting slot 4-1 to limit horizontal displacement), and fix the vise on the workbench by passing the bolt through the bolt tightening hole 4-5 on the rotating plate 4-4. If it is necessary to fine-tune the vise angle, loosen the bolt, rotate the rotating plate 4-4 around the rotation axis 4-3 to the appropriate angle (use the angle adjustment function of the rotating plate 4-4), and then tighten the bolt to complete the fixation.

[0026] The power source mounting plate 4-7 serves as a platform for the power source (pneumatic pump, hydraulic station, etc.). The planar support ensures that the power source is placed stably and prevents it from shifting due to vibration during operation. The mounting frame 4-6 acts as a "bridge" connecting the clamp seat 1 and the power source mounting plate 4-7, transferring the weight of the power source to the clamp seat 1. At the same time, it ensures that the relative position of the power source and the vise body is fixed, ensuring smooth connection of the power transmission pipeline.

[0027] Place the power source on the power source mounting plate 4-7 (using the mounting plate's load-bearing capacity to ensure the power source is stable). The power source mounting plate 4-7 is connected to the clamp base 1 via the mounting bracket 4-6. Insert the plug shaft 5 at one end of the mounting bracket 4-6 into the corresponding hole of the power source mounting plate 4-7 (using the positioning function of the plug shaft 5 to achieve quick assembly) to ensure the power source is installed securely. For precise positioning scenarios, insert the positioning plug shaft 6 at one end of the mounting bracket 4-6 into the outer wall of the clamp base 1 (using the positioning plug shaft 6 to limit the shaking of the mounting bracket 4-6).

[0028] The clamping plate 3-9 directly contacts the workpiece and adapts to workpieces of different shapes through different structures (flat opening, V-shaped opening, etc.). It also prevents clamping force from directly acting on the workpiece surface and causing damage, thus playing a dual role of "protecting the workpiece and enhancing clamping stability." Serving as a "fixed fulcrum" when clamping the workpiece, it cooperates with the clamping jaws 3-3 to form a clamping space, bearing the reaction force transmitted by the workpiece and ensuring that the workpiece does not shift during clamping. The drive screw 3-5, as the "power transmission component" for the translation of the clamping jaws 3-3, converts power into linear motion through rotation, driving the clamping jaws 3-3 to move along the drive cavity 3-1. It is the core component for adjusting the clamping range. 3-4 is fixed to the bottom of the clamping jaw 3-3 and forms a threaded connection with the drive screw 3-5, converting the rotational motion of the drive screw 3-5 into its own linear motion, thereby driving the clamping jaw 3-3 to translate. It is a "rotation to linear" conversion component. The sliding rail 3-6 provides a "guide channel" for the movement of the drive piece 3-4, restricting the displacement of the drive piece 3-4 in the direction perpendicular to the movement direction, ensuring that the clamping jaw 3-3 does not wobble when translating, and ensuring clamping accuracy. The drive bar 3-7 cooperates with the sliding rail 3-6 and is embedded inside the rail, further enhancing the guiding effect of the drive piece 3-4, preventing the drive piece 3-4 from deviating during the movement, and ensuring that the clamping jaw 3-3 moves smoothly.

[0029] Rotate the drive screw 3-5, one end of which extends out of the drive shaft 3-10 of the drive cavity 3-1 (external force is transmitted to the drive screw 3-5 through the drive shaft 3-10). Since the drive screw 3-5 is threadedly connected to the drive plate 3-4, and the drive bar 3-7 on the drive plate 3-4 is embedded in the sliding track 3-6 on the inner wall of the drive cavity 3-1 (the guide effect of the sliding track 3-6 and the drive bar 3-7 prevents the drive plate 3-4 from shifting), when the drive screw 3-5 rotates, it will drive the drive plate 3-4 to move linearly along the sliding track 3-6, which in turn will drive the clamping clamp 3-3 to move along the drive cavity 3-1. According to the length of the workpiece, adjust the clamping clamp 3-3 to a suitable position to ensure that it can effectively cover the workpiece clamping area and prepare for the subsequent clamping action.

[0030] like Figures 1-3 As shown, this embodiment proposes that both the clamping clamp 3-3 and the force clamp 3-2 have insertion slots 3-8, and clamping pieces 3-9 are inserted into the insertion slots 3-8. One end of the drive screw 3-5 is provided with a drive shaft 3-10, and one end of the drive shaft 3-10 extends out of the drive cavity 3-1.

[0031] In some examples, the insertion slot 3-8 provides an installation positioning reference for the clamping piece 3-9, restricts the displacement of the clamping piece 3-9 in the direction perpendicular to the clamping direction, ensures that the relative position of the clamping piece 3-9 with the clamping clamp 3-3 and the force clamp 3-2 is fixed, and guarantees clamping accuracy. The drive shaft 3-10 is the "transfer shaft" connecting the power source and the drive screw 3-5, which transmits the rotational power of the power source to the drive screw 3-5 and is a key node for power transmission.

[0032] For example, such as Figure 3 As shown, one end of the mounting frame 4-6 is provided with a plug-in shaft 5, which is plugged into and fixed to the power source mounting plate 4-7.

[0033] In some examples, the plug-in shaft 5 enables quick plug-in positioning of the mounting bracket 4-6 and the power source mounting plate 4-7, restricts their relative displacement in the horizontal direction, and facilitates the disassembly and replacement of the power source mounting plate 4-7.

[0034] For example, such as Figure 3 As shown, a positioning shaft 6 is provided at one end of the mounting frame 4-6. The positioning shaft 6 is inserted into the outer side wall of the clamp seat 1. An anti-slip block 7 is provided on the side wall of the positioning shaft 6.

[0035] In some examples, the positioning pin 6 further enhances the connection stability between the mounting frame 4-6 and the clamp seat 1. By inserting it into the outer wall of the clamp seat 1, it limits the swaying of the mounting frame 4-6 in the direction perpendicular to the side wall of the clamp seat 1. The anti-slip block 7 on the side wall increases the friction to prevent the positioning pin 6 from loosening in a vibration environment, ensuring the position stability of the power source mounting plate 4-7. The anti-slip block 7 on the side wall of the positioning pin 6 enhances stability and prevents the power source mounting plate 4-7 from shifting during operation.

[0036] For example, such as Figure 1 As shown, the side wall of the clamp seat 1 has a cleaning port 8, which is connected to the interior of the drive cavity 3-1.

[0037] In some examples, the cleaning port 8 is located on the side wall of the clamp seat 1 and communicates with the interior of the drive cavity 3-1. It serves as an "impurity discharge channel" to facilitate the insertion of tools (compressed air gun, brush) into the drive cavity 3-1 to remove internal debris and prevent impurities from accumulating.

[0038] For example, such as Figure 1 As shown, drive ports 9 are provided at both ends of the clamp seat 1. A connecting bearing 10 is provided inside the drive port 9. The drive screw 3-5 is movably connected to the connecting bearing 10.

[0039] In some examples, drive port 9 is used to house the linkage bearing 10, which in turn drives the lead screw 3-5 to rotate smoothly, increasing the lubrication of the lead screw 3-5.

[0040] For example, such as Figure 1 As shown, a locking bolt 11 is provided on the clamping plate 3-9, and the positions of the force clamp 3-2 and the clamping clamp 3-3 correspond to each other.

[0041] In some examples, the locking bolt 11 locks the clamping piece 3-9 to the clamping clamp 3-3 and the force clamp 3-2, preventing the clamping piece 3-9 from loosening due to the reaction force of the workpiece during the clamping process. It is a key fastener for transmitting clamping force.

[0042] When in use, the pneumatic hydraulic vise uses pneumatic / hydraulic power as its core drive source. Through the logical chain of "power transmission - motion conversion - clamping execution - installation adaptation", it achieves stable clamping of workpieces and flexible installation of equipment. Its core lies in using the pressure energy of the pneumatic or hydraulic system to convert it into mechanical energy, and then transmitting the power to the clamping structure through precision transmission components. At the same time, it can be adapted to different working scenarios with the help of the switching installation component 4, ultimately meeting the processing and clamping needs of various workpieces.

[0043] After the pneumatic pump or hydraulic station (power source) is started, it converts the pressure energy of compressed air or hydraulic oil into rotational power. Taking pneumatic drive as an example, compressed air enters the pneumatic motor, driving the internal blades to rotate and generating continuous rotational torque; hydraulic drive, on the other hand, drives the rotor of the hydraulic motor to rotate through hydraulic oil, also outputting rotational power. This power is transmitted to the drive shaft 3-10 through pipelines and connectors, providing the energy basis for subsequent movement.

[0044] The drive shaft 3-10 is rigidly connected to the drive screw 3-5 (e.g., by key or welding), and the rotational power output from the power source directly drives the drive screw 3-5 to rotate synchronously. Since the drive screw 3-5 and the drive plate 3-4 at the bottom of the clamping jaws 3-3 are connected by threads (the screw has an external thread, and the drive plate 3-4 has an internal thread), according to the principle of screw transmission, the rotational motion of the screw can be converted into the linear motion of the drive plate 3-4—when the screw rotates clockwise, the drive plate 3-4 moves along the screw axis towards the clamping jaws 3-2; when it rotates counterclockwise, the drive plate 3-4 moves away from the clamping jaws 3-2, thus adjusting the clamping range and clamping / releasing the workpiece.

[0045] The drive bar 3-7 on the side wall of the drive plate 3-4 is embedded in the sliding rail 3-6 on the inner side wall of the drive cavity 3-1, forming a "guide rail-slider" mating structure. The core function of this structure is to restrict the rotational freedom of the drive plate 3-4, allowing it to move linearly only along the axial direction of the sliding rail 3-6, preventing the drive plate 3-4 from rotating synchronously with the drive screw 3-5, and ensuring that the clamping clamp 3-3 does not wobble or deviate during translation. At the same time, the precise fit between the sliding rail 3-6 and the drive bar 3-7 (with a gap controlled within 0.01-0.03mm) further guarantees the translational accuracy of the clamping clamp 3-3, providing a guarantee for the precise clamping of the workpiece.

[0046] As the drive plate 3-4 moves the clamping jaws 3-3 towards the force-bearing jaws 3-2, the space between them gradually decreases until the clamping plates 3-9 on both contact the workpiece surface. At this point, the power source continues to output power, and the drive screw 3-5 continues to push the clamping jaws 3-3, gradually increasing the pressure (clamping force) exerted by the clamping plates 3-9 on the workpiece. The magnitude of the clamping force is determined by the output pressure of the power source—by adjusting the air pressure of the pneumatic pump or the oil pressure of the hydraulic station, the thrust of the drive screw 3-5 can be controlled, thereby adjusting the clamping force. This ensures the workpiece is firmly clamped (preventing displacement during processing) while avoiding excessive clamping force that could damage the workpiece.

[0047] Clamping plates 3-9 are connected to clamping clamps 3-3 and force-bearing clamps 3-2 via insertion slots 3-8. Clamping plates 3-9 with different structures (flat-mouth, V-shaped, etc.) can adapt to workpieces of different shapes: flat-mouth clamping plates 3-9 increase the contact area with square workpieces through planar contact, improving clamping stability; V-shaped clamping plates 3-9 position cylindrical workpieces through their inclined surfaces on both sides, preventing the workpiece from rolling during clamping. At the same time, clamping plates 3-9 are usually made of wear-resistant alloys with a hardness lower than that of the workpiece (such as copper alloys, mild steel), or flexible materials such as rubber pads are pasted on the surface to avoid the clamping force acting directly on the workpiece surface, preventing scratches or pressure damage to the workpiece, and achieving the dual effect of "clamping stability + workpiece protection".

[0048] The mounting groove 4-1 at the bottom of the vise base 1 serves as a reference structure, which can mate with the standard slot of the workbench to achieve the initial positioning of the vise. The rotating plate 4-4 in the switching mounting assembly 4 can rotate freely around the rotation axis 4-3, and the bolt tightening holes 4-5 on its surface can be adjusted according to the spacing of the workbench mounting holes. When the spacing of the workbench mounting holes does not match the default hole position of the rotating plate 4-4, the rotating plate 4-4 is rotated to a suitable angle to align the bolt tightening holes 4-5 with the workbench mounting holes, and then tightened with bolts. This allows the vise to be fixed on workbenches of different specifications, improving the versatility of the equipment.

[0049] One end of the mounting bracket 4-6 is connected to the clamp base 1 via a positioning pin 6. The anti-slip block 7 on the side wall of the positioning pin 6 increases friction to prevent the mounting bracket 4-6 from loosening under vibration. The other end is connected to the power source mounting plate 4-7 via a connecting shaft 5, limiting the relative displacement between the two. This structure transmits the weight of the power source to the clamp base 1 through the mounting bracket 4-6, maintaining a relatively fixed position between the power source and the vise body. This prevents the pipeline from falling off or the power transmission from being interrupted due to vibration during operation, ensuring the stability of power transmission.

[0050] The cleaning port 8 on the side wall of the clamp seat 1 is connected to the interior of the drive cavity 3-1. During processing, impurities such as iron filings and oil stains can easily accumulate inside the drive cavity 3-1, potentially causing jamming between the drive screw 3-5 and the drive plate 3-4. Tools (such as compressed air guns or brushes) can be directly inserted through the cleaning port 8. The impact force of compressed air or the wiping action of the brush can remove impurities from the drive cavity 3-1, ensuring the cleanliness of the surfaces of transmission components such as the drive screw 3-5 and drive plate 3-4. This prevents impurities from wearing down components or affecting transmission accuracy, thus extending the service life of the equipment.
