A hand-automatic clamp device for guide rail of corrugated roller grinding machine

Abstract

The present invention discloses a manual automatic clamp for a guide rail of a corrugated roller grinder, which relates to the technical field of grinder processing. The clamp comprises a housing and an adaptively adjustable braking mechanism for maintaining a braking effect on the guide rail in real time. The adaptively adjustable braking mechanism comprises a braking detection component for braking and detecting the braking effect in real time, and a control component for cooperating with the braking detection component to adjust the braking. During use, the clamp can minimize the uneven braking force 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 brake detection component and the control component cooperate to 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 a reduced friction coefficient but unchanged braking force.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grinding machine processing, and in particular to a manual and automatic clamp device for a guide rail of a corrugated roller grinding machine. BACKGROUND

[0002] When a corrugated roller is processed by using a grinding machine, the position of the corrugated roller needs to be changed, and a slide rail is often arranged at the bottom of a clamping piece of the corrugated roller to move in a guided manner. However, because the corrugated roller has a large size, when the movement is stopped and the position is locked, the guide rail is subjected to a large burden only by relying on the guide rail. Therefore, an additional clamp device is arranged on the guide rail to assist in braking and locking. The slide rail clamp device is a clamp device element for a linear guide rail and an optical axis, and is also called a guide rail brake, a guide rail lock, or a guide rail locking device. The main functions of the slide rail clamp device include fixing a workbench, precise positioning, preventing vibration, and improving rigidity.

[0003] In the prior art, the brake block is an integral whole, but in the process of use, the brake block is subjected to a load, which may cause non-uniform braking force of the brake block, resulting in uneven wear. In addition, when the clamp device brakes, the contact surface of the brake block and the slide rail is gradually worn, the worn friction surface gradually becomes relatively smooth, the friction coefficient of the friction surface of the brake block decreases, and the existing clamp device cannot detect the wear of the friction surface, so as to automatically adjust the clamping force, so that the pressure applied in the braking process is constant. However, because the friction coefficient decreases, if the same braking force is used, the effect of complete braking may not be achieved, resulting in inertial sliding, and a distance deviation is generated. SUMMARY

[0004] The technical scheme of the present application provides a solution significantly different from the prior art to solve the technical problem that the existing clamp device cannot automatically judge the wear of the friction surface and adjust the braking force according to the wear.

[0005] The technical scheme of the present application is as follows: a manual and automatic clamp device for a guide rail of a corrugated roller grinding machine, comprising a shell, a self-adaptive adjusting brake mechanism for real-time brake effect of the guide rail, a flow channel for pressurization arranged in the shell, a manual operator for manual pressurization arranged through the shell, the self-adaptive adjusting brake mechanism comprising a brake detection assembly for braking and real-time detection of the brake effect, and a regulating assembly for adjusting the brake detection assembly.

[0006] Furthermore, the brake detection assembly includes a brake module, which is located on one side of the flow channel and is composed of several brake blocks. An auxiliary friction block is provided on one side of the brake block, and the auxiliary friction block and the brake block are connected by a guide sleeve rod, and several extrusion and contraction bags are provided in the auxiliary friction block, and the guide sleeve rod passes through the extrusion and contraction bags, and the cross-section of the guide sleeve rod is T-shaped, which can have an extrusion effect on the extrusion and contraction bags. The brake block and the shell are slidably connected by a return spring, and a liquid replenishing box is provided on the shell, and the liquid replenishing box is located on one side of the brake block, and the liquid replenishing box and the several extrusion and contraction bags are connected by a connecting pipe, and an extrusion plate is provided in the liquid replenishing box, and a pressure sensor is provided 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 is deformable and hard.

[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, and 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. A signal receiving processor is arranged on the bottom side of the connecting spring telescopic rod for receiving the signal transmitted by the pressure sensor and then changing the resistance of the electromagnetic resistance ring according to the signal.

[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 present invention has the following beneficial effects:

[0012] First, during use, the traditional one-piece brake pad is first transformed into a combination of several small brake pads. During the braking process, the existing brake pad 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. For this reason, it is transformed into a combination of several smaller brake pads so that the surface is formed by the combination of several lines. At the same time, the smaller brake pad can greatly avoid uneven braking force during braking, which leads to local wear. When wear still occurs somewhere, it can be adjusted and retracted separately for independent control without affecting the use of other brake pads.

[0013] Secondly, in the process of use, when the friction surface of the brake block is used continuously, the friction coefficient of the friction surface decreases, so that the original brake force that can complete braking cannot complete braking. Therefore, after the friction coefficient of the friction surface decreases, the brake force needs to be adjusted correspondingly, but the adjusted brake force should be in a suitable state of just being able to complete braking. Otherwise, although an excessive brake force can complete braking, it will accelerate the wear of the friction surface or the sliding rail contact surface. At this time, by detecting the brake assembly, the brake effect can be detected in real time during braking, to determine whether the brake block completes braking under the brake force. If the brake block does not complete braking, the brake force will continue to be increased until the worn friction surface completes braking under the increased brake force. At this time, the increase of the brake force is stopped. This process does not require human intervention, and the effect is realized synchronously during braking.

[0014] In summary, in the process of use of the clamp, first, the brake block changes the structure, so that the uneven phenomenon of the brake force during braking can be reduced as much as possible. When local wear occurs, the brake block can be adjusted individually. When the friction coefficient decreases due to wear of the friction surface, the cooperation of the brake detection assembly and the control assembly can detect the braking condition in real time and process the detection result to change the brake force, so that the situation of reduced braking effect due to the decrease of the friction coefficient and the unchanged brake force is avoided.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] The following will be described in detail Figures 1 to 9 The embodiment of the present application provides a kind of hand-operated automatic clamp for guide rail of corrugated roller grinding machine, including shell 1, also include self-adapting brake mechanism 2 for real-time brake effect to guide rail, the shell 1 is equipped with for carrying out pressurization flow passage 12, the shell 1 is provided with the manually operated operator 13 that can be manually pressurized, the self-adapting brake mechanism 2 includes brake detection assembly 22 for playing brake and real-time detection of brake effect and regulating and controlling component 21 for adjusting brake of brake detection assembly 22 work.

[0036] When working, the clamp in the process of use, first brake block 221 carries out structural change, so that it can reduce the phenomenon of uneven brake force as far as possible during braking, while when local wear can be adjusted individually, and when the friction surface wears and causes brake coefficient to drop, the cooperation of brake detection assembly 22 and regulating and controlling component 21 can detect the brake condition in real time, and the detection result is handled, the brake force is changed, to avoid the situation that brake effect is reduced due to the brake force unchanged caused by the decrease of friction coefficient.

[0037] Specific, the brake detection assembly 22 comprises a brake module, the brake module is located in one side of the flow channel 12, and the brake module is combined by several brake blocks 221, one side of the brake block 221 is provided with an auxiliary friction block 226, the auxiliary friction block 226 and the brake block 221 are connected through a guide sleeve rod 227, and several extrusion shrink capsules 228 are arranged in the auxiliary friction block 226, the guide sleeve rod 227 penetrates the extrusion shrink capsule 228, and the guide sleeve rod 227 is T-shaped in cross section and can extrude the extrusion shrink capsule 228, the brake block 221 is slidably connected with the shell 1 through a return spring, the shell 1 is provided with a liquid replenishing box 225, and the liquid replenishing box 225 is located at one side of the brake block 221, the liquid replenishing box 225 and the several extrusion shrink capsules 228 are connected through a connecting pipe 222, the liquid replenishing box 225 is provided with an extrusion plate 224, one side of the extrusion plate 224 is provided with a pressure sensor 223.

[0038] Specific, the auxiliary friction block 226 adopts a material with large surface viscosity and wear resistance, such as addition type silicone rubber.

[0039] When working, the brake module is actually braked by cooperation of several brake blocks 221 and the auxiliary friction block 226 connected with the side wall, at this time, the overall friction area does not change much, under the condition that the braking force is unchanged, the braking effect and the braking coefficient are related to the friction area, at this time, the braking effect that can be provided by the brake block 221 does not change, but if the friction surface of the brake block 221 is worn, and the auxiliary friction block 226 adopts rubber material, if the brake block has a movement trend, but at this time, the auxiliary friction block 226 does not have a movement trend due to the viscosity, so that the auxiliary friction block 226 and the brake block 221 have a relative movement, and then the relative movement trend is detected, so as to judge whether the friction surface of the brake block 221 is worn.

[0040] Specific, the extrusion plate 224 adopts a material with deformation ability and certain hardness, such as plastic plastic, and since the extrusion plate 224 is connected with the liquid replenishing box 225 at both ends, when deformation occurs, the middle position of the extrusion plate 224 will have a bending trend, so as to abut the pressure sensor 223 and provide extrusion force for the pressure sensor 223.

[0041] Specific, the control component 21 includes a matching block 211, the matching block 211 is located at the other side of the flow channel 12, the matching block 211 and the shell 1 between the setting has a connecting spring telescopic rod 213, the fixed end of the connecting spring telescopic rod 213 is provided with an electromagnetic resistance ring 212, the connecting spring telescopic rod 213 top is provided with a controller 214, and the controller 214 is located at the side of the matching block 211, the connecting spring telescopic rod 213 bottom side is provided with 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.

[0042] Specific, the electromagnetic resistance ring 212 resistance adjustment adopts electromagnetic adjustment, such as using electromagnetic damper or magnetic rheological damper.

[0043] When working, because of electromagnetic resistance adjustment, at this time through the cooperation of the electromagnetic resistance ring 212 and the connecting spring telescopic rod 213 active end, the connecting spring telescopic rod 213 is contracted, at this time the resistance of contraction can be adjusted, the pressure of the matching plate is provided by the pressure in the flow channel 12, at this time the resistance is used to overcome the pressure, for this reason, the greater the resistance, the greater the pressure in the flow channel, finally the greater the pressure on the brake block 221.

[0044] Working principle; in use, the brake can use manual or hydraulic control, connect the hydraulic control flow pipe with the flow channel 12, so that the hydraulic pressure enters the shell 1 through the flow channel 12, and the brake block 221 is extruded by the hydraulic pressure, so that the brake block 221 and the auxiliary friction block 226 are displaced, at this time the friction surface of the brake block 221 is in contact with the slide rail, so as to complete the brake of the slide rail, when the initial pressure, there is a gap between the matching block 211 and the controller 214, the matching block 211 does not move or moves in a small range under the action of the electromagnetic resistance ring 212 and the connecting spring telescopic rod 213 (the matching block 211 does not contact the controller 214), the hydraulic pressure preferentially pushes the brake block 221 to contact the slide rail.

[0045] But with the continuous use, the friction surface will appear some wear and tear (the wear and tear of the friction surface is mainly aimed at the friction surface of the friction surface becomes 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 friction surface size and the braking force, at this time, if the braking effect is needed, the braking force needs to be increased, at this time, in the process of braking, the brake block 221 and the auxiliary friction block 226 will still be in contact with the slide rail, but due to the insufficient braking effect at this time, the brake block 221 still has a movement trend, but due to the fact that the auxiliary friction block 226 is made of a material with viscosity, the auxiliary friction block 226 is in contact with the surface of the slide rail at this time, which 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 (i.e. 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 extruding the extrusion and contraction capsule 228, extruding the liquid in the extrusion and contraction capsule 228 through the connecting pipe 222 to the liquid box 225, and then extruding the extrusion plate 224 in the liquid box 225, so that the extrusion plate 224 has a deformation trend and bends, but due to the fact that the pressure sensor 223 is fixedly arranged in the liquid box 225 at this time, the bending deformation of the extrusion plate 224 will cause the surface of the pressure sensor 223 to bear an abnormally large pressure, so that the pressure changes abnormally, and it can be concluded that the friction coefficient of the brake block 221 of the clamp is reduced, if it is not reduced, the clamp will not move after braking, which should be immediate braking, at this time, the signal receiving processor receives the signal and increases the resistance of the electromagnetic resistance ring 212, at this time, the liquid continues to enter (when the liquid is controlled, the alarm will stop supplying pressure when the brake block 221 moves and contacts the controller 214), and the damping increases, which causes the connecting spring expansion rod 213 to be unable to contract, at this time, the pressure will be continuously increased, so that the braking force of the brake block 221 on the surface of the slide rail will also be increased, until the brake block 221 no longer moves relative to the slide rail, at this time, the pressure sensor 223 cannot be sensed, at this time, the damping value no longer changes, the cooperating block 211 moves under the action of the hydraulic pressure, thereby contacting the controller 214 to stop supplying pressure and complete 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 the accuracy, the guide rail is reset, thereby ensuring the machining accuracy, when manual operation is adopted, the manual operator 13 is rotated, the liquid in the manual operator 13 is extruded, thereby pressurizing the flow channel 12, when the alarm signal appears, the operation is stopped;

[0046] At the same time, during braking, the plurality of brake blocks 221 are combined, and the brake block 221 surface is relatively small, so that the pressure uniformity can be improved during pressure braking, and the braking uniformity is ensured.

[0047] The above examples are only exemplary embodiments of the present application and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements are also considered to fall within the protection scope of the present application.
