Description

Technical Field

[0001] The invention relates to the technical field of grinder processing, in particular to a manual automatic clamp for a guide rail of a corrugated roller grinder. Background Art

[0002] When using a grinder to process corrugated rollers, since the position of the corrugated rollers needs to be changed, a slide rail is often set at the bottom of its clamping part to guide the movement. However, due to the large size of the corrugated rollers, when stopping and locking the position, relying solely on the guide rail will cause a large burden on the guide rail. For this reason, an additional clamp will be set on the guide rail for auxiliary braking and locking. The slide rail clamp is a clamp element for linear guides and optical axes, also known as guide rail brakes, guide rail locks or guide rail locking devices. Their main functions include fixing the workbench, precise positioning, preventing vibration and improving rigidity.

[0003] During use of the existing brake, the brake block is a whole. However, during use, the influence of the load may cause the braking force applied by the brake block to be non-uniform, resulting in uneven wear. When the brake is braking, the contact surface between the brake block and the slide rail will gradually wear, and the worn friction surface will gradually turn into a relatively smooth state, so that the friction coefficient of the friction surface of the brake block decreases. The existing brake cannot detect the wear of the friction surface, so as to automatically adjust the clamping force, so that the pressure applied during the braking process is constant. However, due to the decrease in friction coefficient, if the same braking force is still used, it may not be enough to achieve a complete braking effect, resulting in an inertial sliding situation, causing a distance deviation. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. The embodiment of the present invention provides a manual automatic clamp for the guide rail of a corrugated roller grinder to solve the technical problem that the existing clamp cannot automatically determine the wear condition of the friction surface and adjust the braking force according to the wear condition.

[0005] The embodiment of the present invention adopts the following technical scheme: a manual automatic clamp for the guide rail of a corrugated roller grinder, comprising a shell, and also comprising an adaptively adjustable braking mechanism for maintaining a braking effect on the guide rail in real time, a flow channel for pressurizing is opened in the shell, a manual operator for manually pressurizing is arranged through the shell, and the adaptively adjustable braking mechanism comprises a braking detection component for braking and real-time detection of the braking effect and a control component for cooperating with the braking detection component to adjust the braking.

[0006] Furthermore, the brake detection component includes a brake module, which is located on one side of the flow channel, and the brake module is composed of a plurality of brake blocks, an auxiliary friction block is arranged on one side of the brake block, the auxiliary friction block and the brake block are connected by a guide sleeve rod, and a plurality of extrusion and shrinkage bags are arranged in the auxiliary friction block, the guide sleeve rod penetrates the extrusion and shrinkage bags, and the guide sleeve rod has a T-shaped cross-section that can squeeze the extrusion and shrinkage bags, the brake block is slidably connected to the shell through a return spring, a liquid replenishment box is arranged on the shell, and the liquid replenishment box is located on one side of the brake block, the liquid replenishment box and the plurality of extrusion and shrinkage bags are connected by a connecting pipe, an extrusion plate is arranged in the liquid replenishment box, and a pressure sensor is arranged on one side of the extrusion plate.

[0007] Furthermore, the auxiliary friction block is made of a material with high surface viscosity and wear resistance, such as addition-type silicone rubber.

[0008] Furthermore, the extruded plate is made of a material that has deformation capability and hardness.

[0009] Furthermore, the regulating component includes a matching block, which is located on the other side of the flow channel, a connecting spring telescopic rod is arranged between the matching block and the shell, an electromagnetic resistance ring is arranged in the fixed end of the connecting spring telescopic rod, a controller is arranged above the connecting spring telescopic rod, and the controller is located on one side of the matching block, and a signal receiving processor for receiving the signal transmitted by the pressure sensor and then changing the resistance of the electromagnetic resistance ring according to the signal is arranged on the bottom side of the connecting spring telescopic rod.

[0010] Furthermore, the resistance adjustment of the electromagnetic resistance ring adopts electromagnetic adjustment, such as using an electromagnetic damper or a magnetorheological damper.

[0011] Compared with the prior art, the beneficial effects of the present invention are: First, during use, the traditional one-piece brake block is first transformed into a combination of several small brake blocks. During the braking process, the existing brake block is affected by the liquid pump and the uneven wear during use, resulting in changes in the braking force generated during the braking process, thereby affecting the braking effect. Therefore, it is transformed into a combination of several smaller brake blocks so that it is formed by combining several lines to form a surface. At the same time, the smaller brake block can greatly avoid uneven braking force and local wear during braking. When wear still inevitably occurs somewhere, it can be adjusted and retracted separately for separate control, without affecting the use of other brake blocks; Secondly, during use, as the friction surface of the brake pad is continuously used, the friction coefficient of the friction surface decreases, so that the braking force that was originally able to complete the braking cannot now complete the braking. Therefore, when the friction coefficient of the friction surface decreases, the braking force needs to be adjusted accordingly, but the adjusted braking force should be in a suitable state to just complete the braking. Otherwise, although the excessive braking force can complete the braking, it will accelerate the wear of the friction surface or the contact surface of the slide rail. At this time, the braking effect can be detected in real time during the braking process by detecting the brake assembly to determine whether the brake pad has completed the braking under the braking force. If the braking is not completed, the braking force will continue to be increased until the worn friction surface completes the braking under the increased braking force. At this time, the braking force is stopped from being increased. This process does not require human intervention, and the effect is achieved synchronously during the braking process. To sum up, during the use of the brake, the brake block is first structurally changed so that the uneven braking force can be reduced as much as possible during braking. At the same time, it can be adjusted separately after local wear. When the friction surface wears and causes the braking coefficient to decrease, the cooperation of the brake detection component and the control component can detect the braking situation in real time, and process the detection results to change the braking force, thereby avoiding the situation where the braking effect is reduced due to the reduction of the friction coefficient but the unchanged braking force.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Combine the following Figures 1 to 9 As shown, an embodiment of the present invention provides a manual automatic clamp for a guide rail of a corrugated roller grinder, comprising a shell 1, and also comprising an adaptively adjustable braking mechanism 2 for maintaining a braking effect on the guide rail in real time, a flow channel 12 for pressurizing is provided in the shell 1, a manual operator 13 for manually pressurizing is provided through the shell 1, and the adaptively adjustable braking mechanism 2 comprises a braking detection component 22 for braking and real-time detection of the braking effect, and a control component 21 for cooperating with the braking detection component 22 to adjust the braking thereof.

[0021] When the brake is in operation, first the brake block 221 undergoes structural changes during use, so that the uneven braking force can be reduced as much as possible during braking. At the same time, it can be adjusted separately after local wear. When the friction surface wears and causes the braking coefficient to decrease, the cooperation of the brake detection component 22 and the control component 21 can detect the braking situation in real time, process the detection results, change the braking force, and avoid the situation where the braking effect is reduced due to the reduction of the friction coefficient but the unchanged braking force.

[0022] Specifically, the brake detection component 22 includes a brake module, which is located on one side of the flow channel 12, and the brake module is composed of a plurality of brake blocks 221. An auxiliary friction block 226 is provided on one side of the brake block 221. The auxiliary friction block 226 and the brake block 221 are connected by a guide sleeve rod 227, and a plurality of extrusion and contraction bags 228 are provided in the auxiliary friction block 226. The guide sleeve rod 227 penetrates the extrusion and contraction bags 228, and the cross-section of the guide sleeve rod 227 is T-shaped, which can exert an extrusion effect on the extrusion and contraction bags 228. The brake block 221 is slidably connected to the shell 1 through a return spring. A liquid replenishment box 225 is provided on the shell 1, and the liquid replenishment box 225 is located on one side of the brake block 221. The liquid replenishment box 225 and the plurality of extrusion and contraction bags 228 are connected by a connecting pipe 222. An extrusion plate 224 is provided in the liquid replenishment box 225, and a pressure sensor 223 is provided on one side of the extrusion plate 224.

[0023] Specifically, the auxiliary friction block 226 is made of a material with high surface viscosity and wear resistance, such as addition-type silicone rubber.

[0024] When working, the brake module is actually braked by a plurality of brake blocks 221 and auxiliary friction blocks 226 connected to the side walls. At this time, the overall friction area has not changed much. When the braking force remains unchanged, the braking effect is related to the braking coefficient and the friction area. At this time, the braking effect that the brake block 221 can provide has not changed. However, if the friction surface of the brake block 221 is worn, and since the auxiliary friction block 226 is made of rubber, if the clamping block has a tendency to move, the friction coefficient of the auxiliary friction block 226 does not decrease due to its viscosity. Therefore, the auxiliary friction block 226 does not generate a tendency to move, resulting in a relative movement between the auxiliary friction block 226 and the brake block 221, and then the relative movement trend is detected to determine whether the friction surface of the brake block 221 is worn.

[0025] Specifically, the extrusion plate 224 is made of a material with deformation ability and a certain hardness, such as plastic, and because both ends of the extrusion plate 224 are connected to the liquid refilling box 225, when deformation occurs, the middle position of the extrusion plate 224 will tend to bend, so that it can contact the pressure sensor 223 and provide extrusion force to the pressure sensor 223.

[0026] Specifically, the regulating component 21 includes a matching block 211, which is located on the other side of the flow channel 12, and a connecting spring telescopic rod 213 is arranged between the matching block 211 and the shell 1, and an electromagnetic resistance ring 212 is arranged in the fixed end of the connecting spring telescopic rod 213, and a controller 214 is arranged above the connecting spring telescopic rod 213, and the controller 214 is located on one side of the matching block 211, and a signal receiving processor for receiving the signal transmitted by the pressure sensor 223 and then changing the resistance of the electromagnetic resistance ring 212 according to the model is arranged on the bottom side of the connecting spring telescopic rod 213.

[0027] Specifically, the resistance adjustment of the electromagnetic resistance ring 212 adopts electromagnetic adjustment, such as using an electromagnetic damper or a magnetorheological damper.

[0028] During operation, due to the electromagnetic resistance adjustment, the electromagnetic resistance ring 212 and the movable end of the connecting spring telescopic rod 213 are used in conjunction with each other, so that when the connecting spring telescopic rod 213 is contracted, the contraction resistance can be adjusted. The pressure on the matching plate is provided by the pressure in the flow channel 12. At this time, the resistance is used to overcome the pressure. Therefore, the greater the resistance, the greater the pressure in the flow channel, and ultimately the greater the pressure on the brake block 221.

[0029] Working principle: When in use, the brake can be controlled manually or hydraulically to connect the hydraulic control flow pipe to the flow channel 12, so that the hydraulic pressure enters the housing 1 through the flow channel 12, and the brake block 221 and the auxiliary friction block 226 are displaced by hydraulic squeezing. At this time, the friction surface of the brake block 221 contacts the slide rail, thereby braking the slide rail. However, with continuous use, the friction surface will wear to a certain extent (the wear is mainly aimed at the friction surface of the friction surface becoming relatively smooth, so that the friction coefficient of the friction surface is reduced). In the process of braking, the initial braking force is set, and the braking effect is affected by the friction coefficient, the size of the friction surface and the braking force. At this time, when the friction coefficient becomes smaller, such as If the braking effect is required, the braking force needs to be increased. At this time, during the braking process, the brake block 221 and the auxiliary friction block 226 will still be in contact with the slide rail. However, since the braking effect is not enough at this time, the brake block 221 will still have a movement trend. However, since the auxiliary friction block 226 is made of a sticky material, the auxiliary friction block 226 is in contact with the surface of the slide rail. At this time, it is in a precise state relative to the brake block 221, resulting in a movement trend between the auxiliary friction block 226 and the brake block 221 (that is, the brake block 221 moves and the auxiliary friction block 226 does not move). At this time, the auxiliary friction block 226 will move along the guide sleeve rod 227, thereby squeezing the squeeze contraction bag 228, and the liquid in the squeeze contraction bag 228 is squeezed through the connection The tube 222 is squeezed into the liquid replenishing box 225, and then the squeezing plate 224 in the liquid replenishing box 225 is squeezed, so that the squeezing plate 224 has a deformation tendency and bends. However, since the pressure sensor 223 is fixedly arranged in the liquid replenishing box 225 at this time, the squeezing plate 224 is bent and deformed, and the pressure on the surface of the pressure sensor 223 becomes abnormally large. As a result, due to the abnormal change of pressure, it can be concluded that the friction surface coefficient of the brake block 221 of the clamp is reduced. If it is not reduced, after braking, the clamp block will not move at this time, and it should be braked immediately. At this time, the signal receiving processor receives the signal and increases the resistance to the electromagnetic resistance ring 212. At this time, the liquid continues to enter (when using liquid control, at this time when the brake block 221 After it moves and contacts the controller 214, an alarm will be triggered and pressure supply will be stopped. At this time, after the damping increases, the spring telescopic rod 213 connected cannot be retracted. At this time, continuous pressure will be applied, so that the braking force of the brake block 221 on the surface of the slide rail will also increase until the brake block 221 no longer slides relatively. At this time, the pressure sensor 223 cannot sense it, and the damping value no longer changes. The matching block 211 moves under the action of hydraulic pressure, thereby contacting the controller 214, stopping pressure supply, and completing locking. At this time, the damping value is the initial damping value required for the next braking. Due to the relative displacement of this braking, in order to ensure accuracy, the guide rail is reset, so as to brake to ensure processing accuracy. When manual operation is adopted, the manual operator 13 is rotated.Squeeze the liquid in the manual operator 13 to pressurize the convection channel 12. When an alarm signal appears, stop the operation; Meanwhile, during the braking process, since a plurality of brake blocks 221 are combined and the surface of the brake blocks 221 is relatively small, the pressure uniformity can be improved during pressure braking, thereby ensuring the braking uniformity.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
