Description

Clamping device capable of early warning

Technical Field

The utility model relates to the technical field of clamping devices, in particular to a clamping device capable of early warning.

Background

In industrial production, a workpiece is usually clamped by means of a clamping device, and when the workpiece is clamped by the clamping device, the workpiece is usually clamped by means of the clamping device close to the workpiece.

When the clamping device clamps the workpiece, the worker places the workpiece at a preset position, and then drives the clamping device to clamp the workpiece. The clamp only carries out simple clamping operation in the process of clamping the workpiece, and does not have the function of early warning. In other words, the clamping device does not warn the clamping position of the clamping device when clamping the workpiece, i.e. when the clamping device clamps the workpiece, the clamping device needs to manually judge when the workpiece is transferred to the preset position for clamping operation, and the workpiece is released after the workpiece is clamped to the preset position.

In this way, in the process of clamping the workpiece by the clamping device, the worker always needs to concentrate on the work by naked eyes, but the phenomenon of inattention is unavoidable after the worker works for a long time. Thus, after the clamping device clamps the workpiece, the worker may not be able to observe the workpiece in time, and the clamped workpiece cannot be transferred in time, so that the clamping efficiency of the workpiece is affected.

In addition, when the manual naked eyes observe, errors may exist, and the displacement of the clamping device during clamping cannot be accurately judged. When the displacement that removes when clamping device centre gripping is too big, can lead to clamping device to work piece centre gripping excessively for work piece atress warp, and work piece can appear scrapping even when serious, and perhaps also because the displacement that removes when clamping device centre gripping is too little lead to the centre gripping not tight, can influence the subsequent processing of work piece equally.

In an embodiment, the belt moving assembly 20 is implemented to include a cylinder, the movable member 21 is implemented to include a moving end of the cylinder, the fixed member 22 is implemented to include a cylinder body, the belt moving assembly 20 has a cavity 2001, the cavity 2001 defines a first air inlet 2002 and a second air inlet 2003, the first air inlet 2002 and the second air inlet 2003 are both communicated with the cavity 2001, meanwhile, the first air inlet 2002 and the second air inlet 2003 are communicated with a device for charging and discharging air from the outside through a pipeline, a valve is arranged on the pipeline, and a worker controls the charging and discharging of the cylinder by controlling the opening and closing of the valve, so as to achieve the purpose of controlling the moving distance of the movable member 21.

In another embodiment, the belt moving assembly 20 is implemented to include a screw structure, the movable member 21 is implemented to include a moving block and a rotating screw, and the fixed member 22 is implemented to include a mounting body to which the moving block is movably mounted. Therefore, when the position of the moving block needs to be adjusted, the worker rotates the rotating screw rod to drive the moving block to move.

The monitoring assembly 30 includes a trigger member 31 and at least one pre-warning member 32. The pre-warning part 32 is electrically connected with the triggering part 31. The trigger piece 31 includes a moving piece 311 and at least one fixed piece 312, the moving piece 311 is mounted on the movable member 21, and the fixed pieces 312 are respectively mounted at two ends of the fixed member 22, so that when the movable member 21 moves relative to the fixed member 22, the moving piece 311 is driven to synchronously move relative to the fixed piece 312.

Preferably, two pre-warning pieces 32 are provided, two fixing pieces 312 are provided, and two fixing pieces 312 are disposed at intervals at both ends of the fixing member 22.

The movable member 21 moves along the fixed member 22 a predetermined distance away from the mounting part 10, and the movable member 21 drives the movable part 311 to approach one of the fixed parts 312, and the movable part 311 and/or one of the fixed parts 312 forms a passage, and triggers one of the early warning parts 32 electrically connected to one of the fixed parts 312 to send out an early warning, where the movable member 21 defines a positioning position.

The movable member 21 moves along the fixed member 22 by a predetermined distance in a direction approaching the mounting part 10, and the movable member 21 drives the movable part 311 to approach the other fixed part 312, and the movable part 311 and/or the other fixed part 312 form a passage, and triggers the other pre-warning part 32 electrically connected with the other fixed part 312 to send out pre-warning, where the movable member 21 defines a non-positioning position.

Preferably, the warning device 32 is implemented as a warning lamp, and the warning lamp is electrically connected with the fixing device 312, so that whether the circuit is on or not can be intuitively judged by the lighting condition of the warning lamp, and the position of the movable member 21 can be deduced.

In one embodiment, the fixing member 312 is electrically connected to the pre-warning member 32. The mover 311 is provided to have magnetism, the fixture 312 is configured to enable the formation of breaks and paths using magnetic induction. When the movable member 21 moves to the positioning position, the movable member 311 is driven to approach one of the fixing members 312, and under the action of magnetic force lines of the magnetic field, the movable member 311 magnetizes one of the fixing members 312, and at the same time, one of the fixing members 312 is magnetized to form a passage, so that the early warning member 32 electrically connected with one of the fixing members 312 is electrified and gives an early warning. Therefore, the position of the movable member 311 can be monitored according to the warning of the warning member 32, and it is determined that the movable member 21 is at the positioning position at this time.

Similarly, when the movable member 21 moves to the non-positioning position, the movable member 21 drives the movable member 311 to approach the other fixed member 312, and the movable member 311 magnetizes the other fixed member 312 under the action of magnetic force lines of the magnetic field, and the other fixed member 312 is magnetized to form a passage, so that the warning member 32 electrically connected to the other fixed member 312 is energized and gives a warning.

It should be noted that, when the movable member 21 drives the moving member 311 to move, the two fixing members 312 are not magnetized at the same time, while a predetermined distance is provided between the two fixing members 312. In addition, the two fixing pieces 312 correspond to the two different pre-warning pieces 32, so that the movable member 21 can be determined to be in the positioning position or the non-positioning position according to the pre-warning of the two different pre-warning pieces 32.

Preferably, the moving part 311 is implemented to include a magnetic ring mounted to the movable member 21, and the fixed part 312 is implemented to include a magnetic switch, with which the opening and closing of the magnetic switch are controlled to control the connection and disconnection of the circuit, close to or away from the magnetic switch.

In another embodiment, both the moving member 311 and the fixed member 312 are provided to have conductivity. When the moving part 311 contacts with the fixed part 312, a passage is formed, and the corresponding early warning part 32 sends out early warning after being electrified; when the moving member 311 and the fixing member 312 are far away from each other, a circuit breaker is formed, and the pre-warning member 32 corresponding to the circuit breaker stops feeding back after power failure.

Preferably, the moving member 311 is implemented to include a first conductive sheet, the fixing member 312 is implemented to be a second conductive sheet, and a path is formed by the first conductive sheet and the second conductive sheet after contact, so that a circuit is completed, and the circuit is opened when the second conductive sheet and the second conductive sheet are away from each other.

Further, the driving member 40 includes a driving part 41 and a first driving part 42, two ends of the driving part 41 are respectively connected to the first driving part 42 and the movable member 21, and the driving part 41 and the first driving part 42 are rotatably mounted to the mounting part 10.

Specifically, the driving member 41 includes a swing arm 411 and a first link 412, two ends of the first link 412 are pivotally mounted to the swing arm 411 and the first clamping member 51, respectively, one end of the swing arm 411 away from the first link 412 is pivotally mounted to the movable member 21, and the swing arm 411 is rotatably mounted to the mounting member 10. In this way, when the movable member 21 moves in a direction away from the mounting part 10, the movable member 21 pushes the swing arm 411 away from one end of the first link 412, so that the swing arm 411 rotates according to the lever principle, and when the swing arm 411 rotates, the first link 412 is pulled, and finally, one end of the first transmission part 42 away from the first link 412 is driven to be away from the placement area 5001, and further, the first clamping part 51 is driven to be synchronously away from the placement area 5001.

Similarly, when the movable member 21 moves in a direction approaching the mount 10, the first clamping member 51 moves in a direction approaching the placement area 5001, which will not be described again.

Further, the driving member 40 further includes a second transmission member 43, and the second transmission member 43 is pivotally mounted to the mounting member 10.

The swing arm 411 defines a main lever portion 4111 and two branch portions 4112, and the branch portions 4112 are formed by extending the main lever portion 4111 toward both ends. The driving member 41 further includes a second link 413, and the second transmission member 43 is pivotally mounted to the mounting member 10 via the second link 413.

The clamping assembly 50 includes a first clamping member 51 and a second clamping member 52, and a placement area 5001 is formed between the first clamping member 51 and the second clamping member 52. The first clamping member 51 is mounted on an end portion of the first transmission member 42 away from the driver 41, and the second clamping member 52 is mounted on the mounting member 10 and is disposed opposite to the first clamping member 51. The second clamping member 52 is mounted to an end of the second transmission 43 remote from the second link 413. The movable member 21 is arranged such that when the movable member 21 moves relative to the fixed member 22, the movable member 21 drives the driver 41 and the first driver 42 to rotate and finally links the first clamp 51 and/or the second clamp 52 to approach or separate from the placement area 5001

Specifically, when the moving member 21 extends, the swing arm 411 rotates to drive the two branch portions 4112 to rotate synchronously, so as to pull the second transmission member 43 to rotate synchronously, and drive the second clamping member 522 to move synchronously towards the direction close to the placement area 5001, so as to clamp and position the upper and lower ends of the workpiece 900 placed in the placement area 5001 synchronously, and increase the stability of clamping the workpiece 900.

Specifically, when the movable member 21 is at the positioning position, the movable member 21 moves to drive the first driver 41 to rotate, the first driver 41 rotates to drive the first driver 42 to synchronously rotate, and finally, according to the lever principle, the first clamping member 51 is driven to approach the placing area 5001, and clamp and position the workpiece 900 placed in the placing area 5001, which defines that the clamping assembly 50 is in the positioning state at this time; when the movable member 21 is at the non-positioning position, the movable member 21 drives the first driver 41 to rotate reversely, and the first driver 41 drives the first driver 42 to rotate reversely synchronously after rotating reversely, so as to finally drive the first clamping member 51 to be away from the placement area 5001 according to the lever principle, without clamping the workpiece 900, thereby defining that the clamping assembly 50 is at the non-positioning state.

In other words, when the movable member 21 moves in a direction away from the fixed member 22, the mover 311 moves in synchronization with the movable member 21, and when the mover 311 moves, the distance between the mover 311 and the fixed piece 312 changes, the connection or disconnection of the circuit is initiated according to the change in the distance, and the warning is performed by the warning piece 32, thereby judging the position of the movable member 21. When the user determines that the movable member 21 is at the non-positioning position according to the information fed back by the pre-warning unit 32, the user places the workpiece 900 in the placing area 5001, then the movable member 21 moves toward the direction approaching to the mounting unit 10, the movable member 21 moves from the non-positioning position to the positioning position, the movable member 21 pushes the driver 41 to rotate, and the driver 41 drives the first driver 42 to synchronously rotate, so as to finally pull the first clamping unit 51 to approach the placing area 5001, and further clamp the workpiece 900 placed in the placing area 5001.

Similarly, after the movable member 21 is switched to the positioning position, the movable member 311 is driven to move synchronously, and when the movable member 311 moves, the distance between the movable member 311 and the fixed member 312 changes, the circuit is connected or disconnected according to the change of the distance, and the pre-warning member 32 feeds back, and the pre-warning member 32 pre-warns information to determine that the movable member 21 is in a positioning state, at this time, the first clamping member 51 completes positioning of the workpiece 900, then the movable member 21 moves in a direction away from the mounting member 10, and the movable member 21 is switched from the positioning position to the non-positioning position again, and repeats cyclically, so as to complete positioning of the workpiece 900 one by one.

In other words, compared with the conventional clamping device, the early-warning clamping device can monitor the position of the movable member 21 and perform early warning when clamping the workpiece 900, so that a worker can timely transfer the workpiece 900 to the placement area 5001 for clamping operation, the continuity of the worker transferring the workpiece 900 is ensured, and the problem that the worker is easy to fatigue, unclear in observation and easy to error due to long-time eye observation is avoided.

As will be appreciated by those skilled in the art, the worker controls the distance that the belt moving assembly 20 drives the clamping assembly 50 to move each time through the pre-warning of the pre-warning member 32, so as to ensure that the distance that the movable member 21 moves each time is consistent, further ensure that the clamping assembly 50 is accurately positioned each time, and avoid excessive clamping.

The second clamping member 52 is mounted to an end of the second transmission 43 remote from the second link 413. In this way, when the movable member 21 extends, the swing arm 411 rotates to drive the two branch portions 4112 to rotate synchronously, so as to pull the second transmission member 43 to rotate synchronously, and drive the second clamping member 522 to move synchronously towards the direction close to the placement area 5001, so as to clamp and position the upper and lower ends of the workpiece 900 placed in the placement area 5001 synchronously, and increase the stability of clamping the workpiece 900.

Further, the second clamping member 52 includes a guide 521 and a second clamping member 522, the guide 521 includes a movable member 5211 and a limiting member 5212, the movable member 5211 is movably mounted to the limiting member 5212 along a vertical direction, an end of the second transmission member 43 away from the second connecting rod 413 is connected to the movable member 5211, and the second clamping member 522 is mounted to an end of the movable member 5211 away from the second connecting rod 413.

In an embodiment, the guide member 521 has a limiting channel 52101, and the limiting member 5212 is inserted into the limiting channel 52101, so that the moving direction of the limiting member 5212 is limited by the limiting channel 52101.

In another embodiment, the guide member 521 has a limiting groove, the limiting member 5212 is slidably mounted in the limiting groove, and the limiting groove is used to limit the moving direction of the limiting member 5212, which is not described herein.

As will be appreciated by those skilled in the art, the direction of movement of the second clamping member 522 is defined by the guide member 521, so as to ensure that when the second clamping member 522 clamps the workpiece 900 in a positioning manner, the second clamping member 522 applies pressure in a vertical direction, so that the workpiece 900 is uniformly clamped, and the workpiece 900 is prevented from being easily deviated in position during clamping.

Further, the early warning clamping device further comprises a stop member 60, wherein the stop member 60 is mounted on the mounting member 10 and is configured to limit the swing range of the swing arm 411.

Preferably, a moving space 6001 is formed between the stop member 60 and the mounting member 10, and the branch portion 4112 of the swing arm 411 can move in the moving space 6001 when swinging, so as to avoid exceeding the maximum movement limit when the swing arm 411 moves.

It will be appreciated by persons skilled in the art that the embodiments of the utility model described above and shown in the drawings are by way of example only and are not limiting. The advantages of the present utility model have been fully and effectively realized. The functional and structural principles of the present utility model have been shown and described in the examples and embodiments of the utility model may be modified or practiced without departing from the principles described.
