Description

Technical Field

[0001] This invention relates to the field of clamping tools, and more specifically to a pneumatic vise with a self-locking mechanism. Background Technology

[0002] Pneumatic vises are commonly used clamping tools in industrial production, also known as pneumatic bench vises, and are widely used in the automotive, machinery, and electronics industries. Traditional pneumatic bench vises suffer from drawbacks such as a small clamping force adjustment range (either too large or too small), failing to meet the requirements of both heavy and light clamping. They are also unstable when clamping materials, leading to problems such as material slippage and vibration, which seriously affect production efficiency and product quality.

[0003] Therefore, developing a pneumatic vise with self-locking and positioning functions can improve clamping force, operational reliability and safety, reduce workload and difficulty, and has a wide range of clamping force adjustment to meet the requirements of heavy and light clamping, ensure the accuracy of machined products, and realize semi-automatic and automatic clamping of the vise. It has important practical significance and application value. Summary of the Invention

[0004] The purpose of this invention is to provide a pneumatic vise with a self-locking mechanism to solve the problems of small clamping force adjustment range, either too large or too small force in the prior art, which cannot meet the requirements of heavy and light cutting, unstable clamping, easy to fall off, and vibration.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pneumatic vise with a self-locking mechanism, comprising a vise body, a lead screw fixedly connected to the middle of the vise body; a self-locking mechanism fixedly connected to the left side of the vise body; a movable cover and a fixed baffle connected to the top of the vise body; a power-multiplying cylinder fixedly connected to the rear side of the vise body; and a pneumatic control component fixedly connected to the right side of the vise body.

[0006] Furthermore, a slider nut and a screw nut are mounted on the lead screw.

[0007] Furthermore, the self-locking mechanism includes a self-locking cylinder, a self-locking piston, a self-locking piston rod, a self-locking connecting plate, a pad, a pushing slider, a fixing block, and an anti-deviation plate. The self-locking cylinder is fixedly installed on the left side of the clamp body. The self-locking cylinder has an internal cavity, and the self-locking piston is disposed within the cavity, allowing it to slide within the cavity. The self-locking piston is fixedly connected to the self-locking piston rod. The self-locking connecting plate is fixedly connected to the self-locking piston rod. The pushing slider is fixedly connected to the self-locking connecting plate. The pad is located at the front end of the pushing slider. The fixing block is located behind the pushing slider. The anti-deviation plate is installed below the fixing block.

[0008] Furthermore, the pad and the fixing block have a round hole in the middle, the push slider has a slot in the middle, and the lead screw passes through the hole; the lead screw has a positioning step, and the fixing block fits with the positioning step.

[0009] Furthermore, the movable cover is fixedly connected to the movable jaw; there is a groove below the movable cover, in which the upper part of the sliding nut is nested, and the movable cover moves back and forth with the lead screw under the drive of the sliding nut.

[0010] Furthermore, the pushing slider and the fixed block are provided with matching inclined surfaces; the pushing slider, driven by the piston rod of the self-locking mechanism, can slide relative to the lead screw. When the piston rod of the self-locking mechanism extends, the inclined surface of the pushing slider closes and presses against the inclined surface of the fixed block, and the fixed block presses against the lead screw through the positioning step of the lead screw; thereby pushing the lead screw, the slider nut, the movable cover, and the movable jaw, keeping the movable jaw in a self-locking state; when the pneumatic vise is clamping and processing materials, even if the air pressure is unstable or subjected to external force, the movable jaw will not retract or vibrate; ensuring the safety of material clamping and processing and the processing accuracy of the product. When the piston rod of the self-locking mechanism retracts, it pushes the slider away from the fixed block, and the pneumatic vise is in an unlocked state.

[0011] Furthermore, a fixed jaw and a positioning mechanism are fixedly connected to the fixed baffle; the fixed baffle is fixed above the rear side of the jaw, and the jaw and the fixed baffle have matching slots and blocks; the positioning mechanism is fixedly connected to the fixed baffle.

[0012] Furthermore, the positioning mechanism includes: a positioning mechanism connecting plate, a positioning mechanism cylinder, a positioning mechanism piston, a positioning mechanism piston rod, a positioning mechanism pressure rod, and a positioning mechanism pressure plate; the positioning mechanism connecting plate is fixedly installed above the fixed baffle; the positioning mechanism cylinder is fixedly connected to the positioning mechanism connecting plate; the positioning mechanism cylinder has an internal cavity, and the positioning mechanism piston is disposed within the cavity, allowing the piston to slide within the cavity; the positioning mechanism piston rod is fixedly connected to the right side of the piston; the positioning mechanism pressure rod is fixedly connected to the right side of the piston rod; and the positioning mechanism pressure plate is fixedly connected to the pressure rod. This positioning mechanism is used to move materials placed at the jaws of the pneumatic vise to a suitable position, improving automated processing efficiency and ensuring product quality.

[0013] Furthermore, the positioning mechanism is used to move the material placed at the jaws of the pneumatic bench vise to a suitable position without manual adjustment, thereby improving the processing efficiency of automated production and ensuring the quality of processed products.

[0014] Furthermore, the multiplier cylinder includes: a front end cover, a first cylinder barrel, a first piston, an intermediate end cover, a second cylinder barrel, a second piston, a rear end cover, a piston rod, a fixed rod, a coupling, a piston rod pin, a lead screw pin, and a piston spacer.

[0015] Furthermore, the front end cover is fixedly installed on the rear side of the clamp, and a first cylinder is connected to the rear side of the front end cover. An intermediate end cover is connected to the rear side of the first cylinder, and a second cylinder is connected to the rear side of the intermediate end cover. A rear end cover is connected to the rear side of the second cylinder. The first cylinder has a cavity one inside, and a first piston is installed inside the cavity one, which can slide within the cavity one. The second cylinder has a cavity two inside, and a second piston is installed inside the cavity two, which can slide within the cavity two. A piston rod is fixedly connected between the first piston and the second piston. The first piston and the second piston are separated by a piston spacer. A coupling is located at the front end of the piston rod, and the piston rod and the coupling are connected together by a piston rod pin. There is a gap between the coupling and the piston rod to avoid radial force on the piston rod and ensure the service life of the multiplier cylinder. The lead screw and the coupling are connected together by a lead screw pin. The multiplier cylinder drives the lead screw through the coupling, and then through the slider nut and the movable cover, thereby driving the movable clamp jaws to clamp and release the material.

[0016] Furthermore, the number of cylinders in the multiplier vise is determined by the specifications and dimensions of the multiplier vise and the application. There can be two, three, or more cylinders; there is no limit. Cylinder diameters can be combined in various sizes without restriction. Through its unique air circuit technology, the multiplier vise allows multiple cylinders to operate simultaneously, one, two, or more at a time. The clamping force adjustment range is wide, with the minimum and maximum clamping force ratio reaching tens or even hundreds of times, meeting both heavy and light clamping requirements.

[0017] Furthermore, a pneumatic control assembly is fixedly connected to the right side of the clamp body. There are two types of pneumatic control assemblies. Pneumatic control assembly one includes: a manifold, a pneumatic control assembly fixing plate, control valve 1, control valve 2, control valve 3, pressure regulating valve, and pressure gauge. Pneumatic control assembly two includes: a manifold, a pneumatic control assembly fixing plate, control valve 1, control valve 4, pressure regulating valve, and pressure gauge.

[0018] Furthermore, a self-locking quick-connect connector is fixedly installed on the manifold. This quick-connect connector can be directly connected to an air source or an external solenoid valve air pipe. When directly connected to the air source air pipe, the pneumatic control component can manually control the power vise. When the quick-connect connector is connected to an external solenoid valve, the pneumatic control component can automatically or semi-automatically control the power vise. The pressure gauge displays the compressed air pressure in the working air path of the power vise. The pressure regulating valve adjusts the compressed air pressure of the power vise, thereby adjusting the clamping force when the power vise grips materials.

[0019] Compared with the prior art, the pneumatic vise with a self-locking mechanism provided by the present invention has the following advantages:

[0020] (1) Through the combination of the cylinder diameter of the power-operated pneumatic vise and the unique air circuit of this technology, the multiple cylinders of the pneumatic vise can be operated by one, two or more air passages respectively. The clamping force adjustment range is large, and the cylinder diameters of the power-operated cylinders are different. The ratio of the minimum and maximum clamping force of the power-operated pneumatic vise jaws can reach tens of times or even hundreds of times, which can meet the requirements of heavy clamping and light clamping.

[0021] (2) The self-locking mechanism of the pneumatic vise in this solution is driven by a cylinder. It has a simple and practical structure, small size, and low cost. It improves the stability and self-locking of the pneumatic vise clamping force, ensures the machining accuracy of the machining, and ensures the product processing quality.

[0022] (3) The positioning mechanism of the pneumatic vise in this solution ensures the accuracy of material placement during automated production and guarantees the quality of processed products.

[0023] (4) This solution uses standard pneumatic control components, resulting in low energy consumption and low cost. The ingenious mechanism and pneumatic circuit design in this solution can match different pneumatic circuits. Through manual operation or system control, this vise can achieve manual, semi-automatic and automatic clamping.

[0024] (5) It can economically and efficiently improve production efficiency by 5-20%, greatly reduce the labor intensity of operators, reduce the number of machine operators, and thus reduce labor costs.

[0025] (6) When clamping precision parts, it is difficult for operators to ensure proper clamping every time. This solution can ensure accurate clamping force every time by adjusting the air pressure and the number of working cylinders, thus ensuring the efficiency and quality of precision parts processing.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The invention will now be described in further detail with reference to the accompanying drawings.

[0058] Example 1:

[0059] See Figure 1 and Figure 2 The pneumatic vise includes a vise body, with a lead screw fixedly connected to the middle of the vise body; a self-locking mechanism fixedly connected to the left side of the vise body; a movable cover and a fixed baffle connected to the top of the vise body; a power-multiplying cylinder fixedly connected to the rear side of the vise body; and a pneumatic control assembly fixedly connected to the right side of the vise body.

[0060] See Figure 3 The lead screw is equipped with a slider nut and a lead screw nut.

[0061] See Figure 4The diagram illustrates a self-locking mechanism, comprising a self-locking mechanism cylinder, a self-locking mechanism piston, a self-locking mechanism piston rod, a self-locking mechanism connecting plate, a pad, a push slider, a fixing block, and an anti-deviation plate. The self-locking mechanism cylinder is fixedly installed on the left side of the clamp body. The cylinder has an internal cavity containing a piston that can slide within the cavity. The piston rod is fixedly connected to the right side of the piston. The connecting plate is fixedly connected to the right side of the connecting plate. The pad is located at the front end of the push slider. The fixing block is located behind the push slider. The anti-deviation plate is installed below the push slider.

[0062] See Figure 5 The pad and the fixing block are provided with a round hole in the middle, the push slider is provided with a slot in the middle, and the lead screw passes through the hole; the lead screw has a positioning step, and the fixing block fits with the positioning step.

[0063] See Figure 1 and Figure 2 The movable cover is fixedly connected to the movable jaw; there is a groove below the movable cover, in which the upper part of the sliding nut is nested. Driven by the sliding nut, the movable cover moves back and forth with the lead screw.

[0064] See Figure 6 and Figure 7 The push slider and the fixed block are provided with matching inclined surfaces. Driven by the piston rod of the self-locking mechanism, the push slider can slide relative to the lead screw. When the piston rod of the self-locking mechanism extends, the inclined surface of the push slider closes and presses against the inclined surface of the fixed block. The fixed block presses against the lead screw positioning step, thereby pushing the lead screw, the slider nut, the movable cover, and the movable jaws, keeping the pneumatic vise in a clamping state and increasing the clamping force. This ensures that even if the air pressure is unstable or subjected to external forces, the movable jaws will not retract or vibrate when the pneumatic vise is clamping materials, thus guaranteeing the processing quality of the materials. When the piston rod of the self-locking mechanism retracts, it pushes the slider away from the fixed block, and the pneumatic vise is in an unlocked state, allowing the movable jaws to open. When the piston rod of the pneumatic cylinder extends, the pneumatic vise releases the material.

[0065] See Figure 1 and Figure 2 A fixed jaw and a positioning mechanism are fixedly connected to the fixed baffle. The fixed baffle is fixed to the upper rear side of the jaw, and the jaw body and the fixed baffle have matching slots and blocks; the positioning mechanism is fixedly connected to the fixed baffle.

[0066] See Figure 8 and Figure 9The diagram illustrates a positioning mechanism, comprising: a positioning mechanism connecting plate, a positioning mechanism cylinder, a positioning mechanism piston, a positioning mechanism piston rod, a positioning mechanism pressure rod, and a positioning mechanism pressure plate. The positioning mechanism connecting plate is fixedly mounted above a fixed baffle. The positioning mechanism cylinder is fixedly connected to the positioning mechanism connecting plate. The positioning mechanism cylinder has an internal cavity, within which the positioning mechanism piston is housed and can slide. The positioning mechanism piston rod is fixedly connected to the right side of the positioning mechanism piston. The positioning mechanism pressure rod is fixedly connected to the right side of the positioning mechanism piston rod. The positioning mechanism pressure rod is fixedly connected to the positioning mechanism pressure plate. This positioning mechanism is used to move materials placed at the jaws of a pneumatic vise to a suitable position, improving automated processing efficiency and ensuring product quality.

[0067] See Figure 10 and Figure 11 The diagram shows a multiplier cylinder, which includes: a front end cover, a first cylinder barrel, a first piston, an intermediate end cover, a second cylinder barrel, a second piston, a rear end cover, a piston rod, a fixed rod, a coupling, a lead screw pin, and a piston rod pin.

[0068] The front end cover is fixedly installed on the rear side of the clamp. A first cylinder is connected to the rear side of the front end cover. An intermediate end cover is connected to the rear side of the first cylinder. A second cylinder is connected to the rear side of the intermediate end cover. A rear end cover is connected to the rear side of the second cylinder. A first piston is connected inside the first cylinder. A second piston is connected inside the second cylinder. A piston rod is fixedly connected between the first cylinder and the second cylinder. The first piston and the second piston are separated by a piston spacer. A coupling is located at the front end of the piston rod. The piston rod and the coupling are connected together by a piston rod pin. There is a gap between the coupling and the piston rod to avoid radial force on the piston rod and ensure the service life of the multiplier cylinder. The lead screw and the coupling are connected together by a lead screw pin. The multiplier cylinder drives the lead screw through the coupling, and then through the slider nut and the movable cover, thereby driving the movable clamp jaws to clamp and release the material.

[0069] The number of cylinders in the multiplier cylinder is determined by the specifications and dimensions of the multiplier pneumatic vise and the application. The number of cylinders can be two, three, or more, without limitation. The cylinder diameter can be a combination of different sizes, without restriction. Through the unique air circuit of this technology, the multiplier cylinder allows multiple cylinders of the pneumatic vise to work one, two, or more at a time, with a large range of clamping force adjustment. The ratio of the minimum to the maximum clamping force can reach tens or even hundreds of times, which can meet the requirements of heavy clamping and light clamping.

[0070] See Figure 12 and Figure 13The diagram shows pneumatic control component one, which is located on the right side of the clamp body. Pneumatic control component one includes: a manifold, a pneumatic control component fixing plate, control valve 1, control valve 2, control valve 3, pressure regulating valve, pressure gauge, self-locking quick connector, and pneumatic accessories such as air pipes.

[0071] See Figure 14 The diagram shows a manifold with multiple self-locking quick-connect fittings, which can be connected to either the air source pipe or the solenoid valve pipe. When the self-locking quick-connect fitting is connected to the air source pipe, the pneumatic control component requires manual operation of the pneumatic vise. When the self-locking quick-connect fitting is connected to the external solenoid valve pipe, the pneumatic vise can be controlled semi-automatically or automatically via the control system. The pressure gauge displays the compressed air pressure in the working air path of the pneumatic vise. The pressure regulating valve adjusts the compressed air pressure of the pneumatic vise, thereby regulating the clamping force when the vise grips materials.

[0072] See Figure 15 The diagram shows control valve 1 of pneumatic control component 1. When the pneumatic control component is connected to the air source, control valve 1 is the main valve of the power vise.

[0073] See Figure 16 The diagram shows control valve 2 of pneumatic control component one. When the pneumatic vise is equipped with pneumatic control component one, control valve 2 is used to switch the air path of the first cylinder of the pneumatic vise. When control valve 2 is pulled out, the air path of the first cylinder is connected to the air path of the pneumatic vise jaws moving outward. When control valve 2 is pressed in, the air path of the first cylinder is connected to the air path of the pneumatic vise jaws moving inward.

[0074] See Figure 17 The diagram shows control valve 3 of pneumatic control component one. When the pneumatic vise is equipped with pneumatic control component one, control valve 3 is used to open or close the air path of the first cylinder of the multi-force cylinder. When control valve 3 is in the neutral position, only the second cylinder is ventilated and operates, providing a smaller clamping force. When the jaws of the pneumatic vise move inward to clamp the material, control valve 3 is switched to the right position. When the multi-force cylinder is ventilated, both the first and second cylinders operate, providing a larger clamping force. When the jaws of the pneumatic vise move outward to clamp the material, control valve 3 is switched to the left position. When the multi-force cylinder is ventilated, both the first and second cylinders operate, providing a larger clamping force.

[0075] See Figure 23 , Figure 24 , Figure 25 , Figure 26 This diagram shows the four common air circuits for the operation of the power vise. By adjusting the control valve, a total of 12 common operating conditions can be achieved. The specific operation or control is as follows:

[0076] See Figure 23The diagram shows the air circuit diagram of the Pneumatic Vise with Pneumatic Control Component 1, when manually operated to clamp and loosen the jaws of the Pneumatic Vise when connected to the air source pipe.

[0077] See Figure 23 The power-operated pneumatic vise is equipped with a pneumatic control component. When the jaws of the power-operated pneumatic vise move inward or outward to clamp materials, the power-operated cylinder has the function of changing the number of working cylinders.

[0078] See Figure 23 The Beili pneumatic vise is connected to the air source pipe via the pneumatic control component one, allowing manual control of the vise's air circuit. When the Beili pneumatic vise's jaws move inward to clamp material and require a smaller clamping force, the first cylinder of the Beili pneumatic vise is de-energized, while the second cylinder is energized, and the self-locking mechanism also engages.

[0079] Before operating the power vise, the control valve 3 must be switched to the neutral position so that the air inlet 11.1 of the control valve 3 is not connected to the working air ports 11.2 and 11.3 of the control valve 3. Use a screw wrench to turn the screw and adjust the distance between the movable jaw and the fixed jaw to the appropriate size according to the size of the workpiece.

[0080] The manual operation procedure A is as follows:

[0081] Step A1: Pull out the switch of control valve 1, so that the air inlet 4.1 of control valve 1 is connected to the working air port 4.3 of control valve 1;

[0082] Step A2: Compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.3 → manifold port 5.3 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.3 → self-locking mechanism cylinder port 8.2. The self-locking mechanism cylinder operates, the self-locking mechanism piston rod retracts, and the vise is in the unlocked state.

[0083] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.3 → manifold port 5.3 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.2 → second cylinder port 7.2. When the second cylinder operates, the piston rod of the multiplier cylinder extends, causing the multiplier pneumatic vise jaws to move outward, and the multiplier pneumatic vise is in the open state.

[0084] Step A3: Place the workpiece into the jaws of the power vise;

[0085] Step A4: Press the switch of control valve 1, so that the air inlet 4.1 of control valve 1 is connected to the working air port 4.2 of control valve 1;

[0086] Step A5: Compressed air path: Air source → Manifold port 1.1 → Manifold port 1.2 → Pressure regulating valve port 2.1 → Pressure regulating valve port 2.3 → Control valve 1 port 4.1 → Control valve 1 port 4.2 → Manifold port 5.1 → Manifold port 5.2 → Adapter 1 port 6.1 → Adapter 1 port 6.2 → Second cylinder port 7.1. The second cylinder operates, the piston rod of the multiplier cylinder retracts, causing the multiplier pneumatic vise jaws to move inward, and the multiplier pneumatic vise clamps the material;

[0087] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.2 → manifold port 5.1 → manifold port 5.2 → adapter port 1 port 6.1 → adapter port 1 port 6.3 → self-locking mechanism cylinder port 8.1. When the self-locking mechanism cylinder is activated, the piston rod of the self-locking mechanism extends, pushing the inclined surface of the slider and the inclined surface of the fixed block to close and press together, keeping the jaws of the multiplier pneumatic vise in a clamping state and increasing the clamping force.

[0088] Step A6: Use a pneumatic vise to clamp the material until the material processing steps or other processes are completed manually or by mechanical equipment;

[0089] Step A7: Pull out the switch of control valve 1, so that the air inlet 4.1 of control valve 1 is connected to the working air port 4.3 of control valve 1;

[0090] Step A8: Compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.3 → manifold port 5.3 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.3 → self-locking mechanism cylinder port 8.2. The self-locking mechanism cylinder operates, the self-locking mechanism piston rod retracts, and the vise is in the unlocked state.

[0091] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.3 → manifold port 5.3 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.2 → second cylinder port 7.2. When the second cylinder operates, the piston rod of the multiplier cylinder extends, causing the multiplier pneumatic vise jaws to move outward, thus releasing the material.

[0092] Step A9: Remove the processed material from the power vise manually or mechanically.

[0093] The above steps are the configuration of the pneumatic control component one of this power-operated pneumatic vise. When the jaws move inward to clamp the material, only the second cylinder of the power cylinder works, providing a small clamping force for one operation. In actual operation, the above steps A1 to A9 will be repeated continuously according to the amount of material until all the material is processed.

[0094] See Figure 23 The Beili pneumatic vise is connected to the air source pipe via the pneumatic control component, allowing for manual control of the vise's air circuit. When the vise's jaws move inward to clamp material, requiring a larger clamping force, the first cylinder of the vise is activated, and simultaneously the second cylinder is activated, along with the self-locking mechanism.

[0095] Before operating the power vise, press the switch of control valve 2 to connect the working air port 9.1 of control valve 2 with the air port 9.3 of control valve 2; turn the switch of control valve 3 to the right position to connect the air inlet 11.1 of control valve 3 with the working air port 11.2 of control valve 3; use a screw wrench to turn the screw and adjust the distance between the movable jaw and the fixed jaw to a suitable size according to the size of the workpiece.

[0096] Manual operation procedure B is as follows:

[0097] Steps B1, B2, B3, and B4 are the same as steps A1, A2, A3, and A4 above;

[0098] Step B5: Compressed air path: Air source → Manifold port 1.1 → Manifold port 1.2 → Pressure regulating valve port 2.1 → Pressure regulating valve port 2.3 → Control valve 1 port 4.1 → Control valve 1 port 4.2 → Manifold port 5.1 → Manifold port 5.2 → Adapter 1 port 6.1 → Adapter 1 port 6.2 → Second cylinder port 7.1. The second cylinder operates, the piston rod of the multiplier cylinder retracts, causing the multiplier pneumatic vise jaws to move inward, and the multiplier pneumatic vise clamps the material.

[0099] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.2 → manifold port 5.1 → manifold port 5.2 → adapter port 1 port 6.1 → adapter port 1 port 6.3 → self-locking mechanism cylinder port 8.1. When the self-locking mechanism cylinder is activated, the piston rod of the self-locking mechanism extends, pushing the inclined surface of the slider and the inclined surface of the fixed block to close and press together, keeping the jaws of the multiplier pneumatic vise in a clamping state and increasing the clamping force.

[0100] Synchronously, compressed air travels through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.2 → manifold port 5.1 → manifold port 5.2 → adapter 1 port 6.1 → adapter 1 port 6.4 → control valve 2 port 9.1 → control valve 2 port 9.3 → control valve 3 port 11.1 → control valve 3 port 11.2 → first cylinder port 7.3. The first cylinder operates, increasing the clamping force of the pneumatic vise jaws on the material.

[0101] Steps B6, B7, B8, and B9 are the same as steps A6, A7, A8, and A9 above;

[0102] The above steps are the first operation procedure for configuring the pneumatic control component of this power vise. When the jaws move inward to clamp the material, the first and second cylinders of the power cylinder work simultaneously to provide a large clamping force. In actual operation, the above steps B1 to B9 will be repeated continuously according to the amount of material until all the material is processed.

[0103] See Figure 23 Through the pneumatic control component one, the air circuit of the power vise can be manually controlled. When the jaws of the power vise move outward to clamp the material and a smaller clamping force is required, the first cylinder of the power vise is not ventilated and the second cylinder is ventilated and the self-locking mechanism is also activated.

[0104] Before operating the power vise, the control valve 3 must be switched to the neutral position so that the air inlet 11.1 of the control valve 3 is not connected to the working air ports 11.2 and 11.3 of the control valve 3. Use a screw wrench to turn the screw and adjust the distance between the movable jaw and the fixed jaw to the appropriate size according to the size of the workpiece.

The self-locking mechanism cylinder operates, and the self-locking mechanism piston rod extends.

[0108] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.2 → manifold port 5.1 → manifold port 5.2 → adapter 1 port 6.1 → adapter 1 port 6.2 → second cylinder port 7.1. When the second cylinder operates, the piston rod of the multiplier cylinder retracts, causing the multiplier pneumatic vise jaws to move inward, and the multiplier pneumatic vise is in the open state.

[0109] Step C3: Place the workpiece into the jaws of the power vise;

[0110] Step C4: Pull out the switch of control valve 1, so that the air inlet 4.1 of control valve 1 is connected to the working air port 4.3 of control valve 1;

When the second cylinder operates, the piston rod of the multiplier cylinder extends, causing the multiplier pneumatic vise jaws to move outward, and the multiplier pneumatic vise clamps the material.

[0113] Step C6: The pneumatic vise clamps the material until the material processing steps or other processes are completed manually or by mechanical equipment;

[0114] Step C7: Press the switch of control valve 1, so that the air inlet 4.1 of control valve 1 is connected to the working air port 4.2 of control valve 1;

When the second cylinder operates, the piston rod of the multiplier cylinder retracts, causing the multiplier pneumatic vise jaws to move inward, and the multiplier pneumatic vise releases the material.

[0117] Step C9: Remove the processed material from the power vise manually or mechanically.

[0118] The above steps are the configuration of the pneumatic control component one of this power-operated pneumatic vise. When the jaws move outward to clamp the material, only the second cylinder of the power cylinder works, providing a small clamping force for one operation. In actual operation, the above steps C1 to C9 will be repeated continuously according to the amount of material until all the material is processed.

[0119] See Figure 23 Through the pneumatic control component one, the air circuit of the power vise can be manually controlled. When the jaws of the power vise move outward to clamp the material and a larger clamping force is required, the first cylinder of the power vise is ventilated and the second cylinder is ventilated, and the self-locking mechanism is also activated.

[0120] Before operating the power vise, first pull out the switch of control valve 2 to connect the working air port 9.2 of control valve 2 with the air port 9.3 of control valve 2; turn the switch of control valve 3 to the left position to connect the air inlet 11.1 of control valve 3 with the working air port 11.3 of control valve 3; use a screw wrench to turn the screw and adjust the distance between the movable jaw and the fixed jaw to a suitable size according to the size of the workpiece.

[0121] The manual operation procedure D is as follows:

[0122] Steps D1, D2, D3, and D4 are the same as steps C1, C2, C3, and C4 above;

When the second cylinder operates, the piston rod of the multiplier cylinder extends, causing the multiplier pneumatic vise jaws to move outward, and the multiplier pneumatic vise clamps the material.

[0125] Synchronously, compressed air travels through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.3 → manifold port 5.3 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.4 → control valve 2 port 9.2 → control valve 2 port 9.3 → control valve 3 port 11.1 → control valve 3 port 11.3 → first cylinder port 7.4. The first cylinder operates, increasing the clamping force of the pneumatic vise jaws on the material.

[0126] Steps D6, D7, D8, and D9 are the same as steps C6, C7, C8, and C9 above;

[0127] The above steps are the first operation procedure of the power vise equipped with the air control component. When the jaws move outward to clamp the material, the first and second cylinders of the power cylinder work simultaneously to increase the clamping force.

[0178] See Figure 24 The Beili pneumatic vise is connected to the solenoid valve air pipe via the air control component, and the clamping and releasing of the Beili pneumatic vise is controlled by the control system. When the jaws of the Beili pneumatic vise move outward to clamp the material and a larger clamping force is required, the first cylinder is energized and the second cylinder is energized, the self-locking mechanism is activated, and the positioning mechanism is also activated.

[0179] Before operating the power vise, first pull out the control valve 2 switch to connect the air inlet 9.2 of control valve 2 with the working air port 9.3 of control valve 2; turn the control valve 3 switch to the left position to connect the air inlet 11.1 of control valve 3 with the working air port 11.3 of control valve 3; use a screw wrench to turn the screw and adjust the distance between the movable jaw and the fixed jaw to the appropriate size according to the size of the workpiece.

[0180] The power-operated pneumatic vise is controlled by a system, and its workflow H is as follows:

[0181] Steps H1, H2, H3, H4, H5, and H6 are the same as steps G1, G2, G3, G4, G5, and G6 above;

[0182] Step H7: Compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → solenoid valve 1 port 12.1 → solenoid valve 1 port 12.3 → manifold port 13.2 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.3 → self-locking mechanism cylinder port 8.2. The self-locking mechanism cylinder operates, and the self-locking mechanism piston rod retracts.

[0183] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → solenoid valve 1 port 12.1 → solenoid valve 1 port 12.3 → manifold port 13.2 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.2 → second cylinder port 7.2. When the second cylinder operates, the piston rod of the multiplier cylinder extends, causing the multiplier pneumatic vise jaws to move outward, and the multiplier pneumatic vise clamps the material.

[0184] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → solenoid valve 1 port 12.1 → solenoid valve 1 port 12.3 → manifold port 13.2 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.4 → control valve 2 working port 9.2 → control valve 2 port 9.3 → control valve 3 port 11.1 → control valve 3 port 11.3 → first cylinder port 7.4. The first cylinder operates, increasing the clamping force of the pneumatic vise jaws on the material.

[0185] Steps H8, H9, H10, H11, H12, and H13 are the same as steps G8, G9, G10, G11, G12, and G13 above;

[0186] The above steps describe the operation of this pneumatic vise equipped with the pneumatic control component one, which connects to an external solenoid valve and air pipe. When the vise jaws move outward to clamp the material, the first and second cylinders of the pneumatic vise operate simultaneously, providing a large clamping force for one operation. In actual operation, steps H1 to H13 are repeated continuously depending on the quantity of material to complete the processing of all materials.

[0187] Example 2:

[0188] See Figure 20 and Figure 21 The diagram shows the second pneumatic control component of the power vise: pneumatic control component two (12). The pneumatic control component two is a simplified version of the pneumatic control component one. The number of cylinders working when the power vise jaws move inward to clamp the material can be adjusted. The pneumatic control component two includes: a manifold, a pneumatic control component fixing plate, a control valve 1, a pressure regulating valve, a pressure gauge, a self-locking quick connector, a control valve 4 (11-9), and pneumatic accessories such as air pipes.

[0189] See Figure 22 The diagram shows control valve 4 of pneumatic control component two. When the pneumatic vise is equipped with pneumatic control component two, control valve 4 is used to open or close the air path of the first cylinder of the multi-force cylinder. When control valve 4 is switched to the left position, only the second cylinder is ventilated and operates during the operation of the multi-force cylinder, providing a smaller clamping force. When the jaws of the pneumatic vise move inward to clamp the material, control valve 4 is switched to the right position. During the operation of the multi-force cylinder, both the first and second cylinders are ventilated and operate simultaneously, providing a larger clamping force.

[0190] See Figure 25 The diagram shows the air path of the power vise with air control component 2 connected to the air source pipe.

[0191] See Figure 25 When the jaws of the power vise move inward to clamp the material and a smaller clamping force is required, the first cylinder operates without air supply, the second cylinder operates with air supply, and the self-locking mechanism operates.

[0192] Before operating the power vise, the switch of control valve 4 must be turned to the left position so that the air inlet 16.1 of control valve 4 is not connected to the working air inlet 16.2 of control valve 4. Use a screw wrench to turn the screw and adjust the distance between the movable jaw and the fixed jaw to a suitable size according to the size of the workpiece.

[0193] The manual operation procedure I is as follows:

[0194] Step I1: Pull out the switch of control valve 1, so that the air inlet 4.1 of control valve 1 is connected to the working air port 4.3 of control valve 1;

[0195] Step I2: Compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.3 → manifold port 5.3 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.3 → self-locking mechanism cylinder port 8.2. The self-locking mechanism cylinder operates, the self-locking mechanism piston rod retracts, and the vise is in the unlocked state.

[0196] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.3 → manifold port 5.3 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.2 → second cylinder port 7.2. When the second cylinder operates, the piston rod of the multiplier cylinder extends, causing the multiplier pneumatic vise jaws to move outward, and the multiplier pneumatic vise is in the open state.

[0197] Step I3: Place the workpiece into the jaws of the power vise;

[0198] Step I4: Press the switch of control valve 1, so that the air inlet 4.1 of control valve 1 is connected to the working air port 4.2 of control valve 1;

[0199] Step I5: Compressed air path: air source → manifold air port 1.1 → manifold air port 1.2 → pressure regulating valve air port 2.1 → pressure regulating valve air port 2.3 → control valve 1 air port 4.1 → control valve 1 air port 4.2 → manifold air port 5.1 → manifold air port 5.2 → adapter 1 air port 6.1 → adapter 1 air port 6.2 → second cylinder air port 7.1.

[0200] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.2 → manifold port 5.1 → manifold port 5.2 → adapter port 1 port 6.1 → adapter port 1 port 6.3 → self-locking mechanism cylinder port 8.1. When the self-locking mechanism cylinder is activated, the piston rod of the self-locking mechanism extends, pushing the inclined surface of the slider and the inclined surface of the fixed block to close and press together, keeping the jaws of the multiplier pneumatic vise in a clamping state and increasing the clamping force.

[0201] Step I6: Use a pneumatic vise to hold the material until the material processing steps or other processes are completed manually or by mechanical equipment;

[0202] Step I7: Pull out the switch of control valve 1, so that the air inlet 4.1 of control valve 1 is connected to the working air port 4.3 of control valve 1;

[0203] Step I8: Compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.3 → manifold port 5.3 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.3 → self-locking mechanism cylinder port 8.2. The self-locking mechanism cylinder operates, the self-locking mechanism piston rod retracts, and the vise is in the unlocked state.

[0204] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.3 → manifold port 5.3 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.2 → second cylinder port 7.2. When the second cylinder operates, the piston rod of the multiplier cylinder extends, causing the multiplier pneumatic vise jaws to move outward, thus releasing the material.

[0205] Step I9: Manually remove the processed material from the power vise.

[0206] The above steps describe the configuration of the pneumatic control component two for this power vise, which is directly connected to the air source pipe. When the vise jaws move inward to clamp the material, only the second cylinder of the power cylinder operates, providing a smaller clamping force for each operation. In actual operation, steps I1 to I9 will be repeated continuously depending on the quantity of material until all material is processed.

[0207] See Figure 25 When the jaws of the power vise move inward to clamp the material and require a large clamping force, the first cylinder is vented and the second cylinder is vented, and the self-locking mechanism is activated.

[0208] Before operating the power vise, turn the switch of control valve 4 to the right position so that the air inlet 16.1 of control valve 4 is connected to the working air port 16.2 of control valve 4. Use a screw wrench to turn the screw and adjust the distance between the movable jaw and the fixed jaw to a suitable size according to the size of the workpiece.

The second cylinder works, the piston rod of the multiplier cylinder retracts, causing the multiplier pneumatic vise jaws to move inward, and the multiplier pneumatic vise clamps the material;

[0212] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.2 → manifold port 5.1 → manifold port 5.2 → adapter port 1 port 6.1 → adapter port 1 port 6.3 → self-locking mechanism cylinder port 8.1. When the self-locking mechanism cylinder is activated, the piston rod of the self-locking mechanism extends, pushing the inclined surface of the slider and the inclined surface of the fixed block to close and press together, keeping the jaws of the multiplier pneumatic vise in a clamping state and increasing the clamping force.

[0213] Synchronously, compressed air travels through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → control valve 1 port 4.1 → control valve 1 port 4.2 → manifold port 5.1 → manifold port 5.2 → adapter 1 port 6.1 → adapter 1 port 6.4 → control valve 4 port 16.1 → control valve 4 working port 16.2 → first cylinder port 7.3. The first cylinder operates, increasing the clamping force of the pneumatic vise jaws on the material.

[0214] Steps J6, J7, J8, and J9 are the same as steps I6, I7, I8, and I9 above;

[0215] The above steps describe the operation of this pneumatic vise equipped with pneumatic control component two, which is directly connected to the air source pipe. When the vise jaws move inward to clamp the material, the first and second cylinders of the pneumatic vise operate simultaneously, providing a large clamping force for one operation. In actual operation, steps J1 to J9 will be repeated continuously depending on the quantity of material until all material is processed.

[0216] See Figure 26 The diagram shows the air control component two of the power vise, which is connected to the solenoid valve air pipe and controlled by the control system to clamp and release the power vise.

[0217] See Figure 26 The Beili pneumatic vise controls the clamping and loosening of the jaws through a configuration system. When the jaws of the Beili pneumatic vise move inward to clamp the material and require a smaller clamping force, the first cylinder is not ventilated and the second cylinder is ventilated and activated. The self-locking mechanism and the positioning mechanism are also activated.

[0218] Before operating the power vise, the switch of control valve 4 must be turned to the left position so that the air inlet 16.1 of control valve 4 is not connected to the working air inlet 16.2 of control valve 4. Use a screw wrench to turn the screw and adjust the distance between the movable jaw and the fixed jaw to a suitable size according to the size of the workpiece.

[0219] The power-operated pneumatic vise is controlled by a system, and its workflow K is as follows:

[0220] Step K1: The control system issues a command, solenoid valve 1 coil 2 is energized, and solenoid valve 1 inlet 12.1 is connected to solenoid valve 1 working port 12.3;

[0221] Step K2: Compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → solenoid valve 1 port 12.1 → solenoid valve 1 port 12.3 → manifold port 13.2 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.3 → self-locking mechanism cylinder port 8.2. The self-locking mechanism cylinder operates, the self-locking mechanism piston rod retracts, and the vise is in the unlocked state.

[0222] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → solenoid valve 1 port 12.1 → solenoid valve 1 port 12.3 → manifold port 13.2 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.2 → second cylinder port 7.2. When the second cylinder operates, the piston rod of the multiplier cylinder extends, causing the multiplier pneumatic vise jaws to move outward, and the multiplier pneumatic vise is in the open state.

[0223] Step K3: Place the workpiece into the jaws of the power vise using a loading / unloading machine or manually;

The self-locking mechanism cylinder operates, the self-locking mechanism piston rod retracts, and the vise is in the unlocked state.

[0234] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → solenoid valve 1 port 12.1 → solenoid valve 1 port 12.3 → manifold port 13.2 → manifold port 5.4 → adapter 2 port 10.1 → adapter 2 port 10.2 → second cylinder port 7.2. When the second cylinder operates, the piston rod of the multiplier cylinder extends, causing the multiplier pneumatic vise jaws to move outward, and the multiplier pneumatic vise releases the material.

[0235] Step K13: Remove the processed material placed in the jaws of the power vise by means of a loading / unloading machine or manually.

[0236] The above steps describe the configuration of the pneumatic control component two in this power vise, connected to the solenoid valve air pipe. When the vise jaws move inward to clamp the material, only the second cylinder of the power cylinder operates, providing a smaller clamping force for one operation. In actual operation, steps K1 to K13 are repeated continuously depending on the quantity of material to complete the processing of all materials.

[0237] See Figure 26 The Beili pneumatic vise controls the clamping and loosening of the jaws through a configuration system. When the jaws of the Beili pneumatic vise move inward to clamp the material and require a large clamping force, the first cylinder is vented and the second cylinder is vented, the self-locking mechanism is activated, and the positioning mechanism is also activated.

[0238] Before operating the power vise, the switch of control valve 4 must be turned to the right position so that the air inlet 16.1 of control valve 4 is connected to the working air port 16.2 of control valve 4; use a screw wrench to turn the screw and adjust the distance between the movable jaw and the fixed jaw to a suitable size according to the size of the workpiece.

[0239] The power-operated pneumatic vise is controlled by a system, and its workflow (L) is as follows:

[0240] Steps L1, L2, L3, L4, L5, and L6 are the same as steps K1, K2, K3, K4, K5, and K6 above;

[0241] Step L7: Compressed air path: air source → manifold air port 1.1 → manifold air port 1.2 → pressure regulating valve air port 2.1 → pressure regulating valve air port 2.3 → solenoid valve 1 air port 12.1 → solenoid valve 1 air port 12.2 → manifold air port 13.1 → manifold air port 5.2 → adapter 1 air port 6.1 → adapter 1 air port 6.2 → second cylinder air port 7.1. The second cylinder works, the piston rod of the multiplier cylinder retracts, causing the multiplier pneumatic vise jaws to move inward, and the multiplier pneumatic vise clamps the material;

[0242] Synchronously, compressed air passes through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → solenoid valve port 12.1 → solenoid valve port 12.2 → manifold port 13.1 → manifold port 5.2 → adapter port 16.1 → adapter port 16.3 → self-locking mechanism cylinder port 8.1. When the self-locking mechanism cylinder is activated, the piston rod of the self-locking mechanism extends, pushing the inclined surface of the slider and the inclined surface of the fixed block to close and press together, keeping the jaws of the multiplier pneumatic vise in a clamping state and increasing the clamping force.

[0243] Synchronously, compressed air travels through the following path: air source → manifold port 1.1 → manifold port 1.2 → pressure regulating valve port 2.1 → pressure regulating valve port 2.3 → solenoid valve 1 port 12.1 → solenoid valve 1 port 12.2 → manifold port 13.1 → manifold port 5.2 → adapter 1 port 6.1 → adapter 1 port 6.4 → control valve 4 working port 16.1 → control valve 4 port 16.2 → first cylinder port 7.3. The first cylinder operates, increasing the clamping force of the pneumatic vise jaws on the material.

[0244] Steps L8, L9, L10, L11, L12, and L13 are the same as steps K8, K9, K10, K11, K12, and K13 above;

[0245] The above steps describe the process of configuring the pneumatic control component two of this power vise. When an external solenoid valve air pipe is connected, the power vise jaws move inward to clamp the material. Simultaneously, the first and second power cylinders work to provide a larger clamping force in one operation. In actual operation, steps L1 to L13 will be repeated continuously depending on the quantity of material until all material is processed.

[0246] This pneumatic vise, through adjusting the control valve, can change the number of cylinders operating simultaneously and the direction of material clamping in the jaws. By changing the air supply method, the pneumatic control component can be directly connected to an air source or connected to an external solenoid valve, enabling both manual and automatic control modes. Manual operation or system control allows for manual, semi-automatic, and automatic clamping. Adjusting the control and pressure valves allows for one or two working cylinders within the pneumatic vise, with varying cylinder diameters, resulting in a wide clamping force adjustment range. The minimum and maximum clamping force ratio can reach tens or even hundreds of times, meeting both heavy and light clamping requirements. The self-locking mechanism enhances the stability and self-locking properties of the clamping force. The positioning mechanism ensures accurate material placement during automated production, guaranteeing the quality of processed products.

[0247] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
