Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-6, a workpiece auxiliary mounting device is used for assisting a fixture 1 to mount a workpiece 2, and comprises a base 3, a carrier 4, a pressing block 5 and a driving mechanism 6, wherein the base 3 can be placed beside the fixture 1; the carrying seat 4 is arranged on the base 3 and is positioned right above the clamp 1; the pressing block 5 is arranged on the carrying seat 4 in a vertically movable manner, and the pressing block 5 is horizontally arranged and corresponds to the workpiece 2; the driving mechanism 6 is mounted on the carrier 4 and is in driving connection with the pressing block 5, so that the pressing block 5 is specifically far away from the first position of the workpiece 2 and the second position of the pressing block abutting against the workpiece 2.

Specifically, for easy understanding, in the embodiment of the present utility model, the work auxiliary installation device is used in combination with the workbench 9 and the fixture 1, and the specific usage manner is as follows:

the method comprises the steps of firstly, fixedly mounting a clamp 1 on a workbench 9, and mounting a workpiece 2 to be processed into the clamp 1;

secondly, mounting the base 3 on the workbench 9 and arranging the base beside the clamp 1, and ensuring that the pressing block 5 on the carrying seat 4 is correspondingly positioned right above the workpiece 2, wherein the pressing block 5 is positioned at a first position far away from the workpiece 2;

thirdly, starting a driving mechanism 6 to drive the pressing block 5 to move downwards until the pressing block 5 is positioned at the second position, and pressing the surface of the workpiece 2 by the pressing block 5, wherein in the process, the workpiece 2 is flattened, so that the surface flatness of the workpiece 2 meets the requirement;

fourth, through the work piece 2 that anchor clamps 1 centre gripping locking roughness reached standard to start actuating mechanism 6 and order about briquetting 5 to return to the first position from the second position, briquetting 5 keep away from adjusted work piece 2 this moment, the user takes off base 3 from workstation 9, can carry out the processing operation to work piece 2 that finishes installing.

It should be noted that in the first step, when the workpiece 2 is mounted on the fixture 1, the workpiece 1 and the two clamping jaws of the fixture 1 are in a transitional fit state, and in this state, the workpiece 2 can move if and only if an external force is applied, so as to avoid that the workpiece 2 cannot be driven when the pressing block 5 abuts against the surface of the workpiece 2; in the fourth step, after the flatness of the surface of the workpiece 2 reaches the standard, the user needs to directly lock the workpiece 2 by the fixture 1 to avoid shaking during the processing.

In addition, in order to avoid shaking during the whole operation of the workpiece auxiliary installation device, the placement stability of the base 3 is improved; the base 3 is generally made of a solid material (for example, iron block, etc.), and is provided with a certain weight, or is directly fixed to the table 9 by using bolts.

In summary, the base 3 and the carrying seat 4 are designed to be used for installing the pressing block 5, so that the pressing block 5 is horizontally placed and corresponds to the workpiece 2 to be processed; the driving mechanism 6 is designed to drive the pressing block 5 away from or against the workpiece 2 to be processed; because the pressing block 5 is horizontally arranged, the surface of the workpiece 2 can be flattened in the process of extruding the workpiece 2, so that the surface flatness of the workpiece 2 is ensured, and the subsequent processing operation of the workpiece 2 is convenient; compared with the prior art, the auxiliary workpiece mounting device does not need to manually read a meter or continuously adjust the position of the workpiece 2 by workers, thereby effectively improving the mounting accuracy and shortening the mounting time of the workpiece 2.

Referring to fig. 2, 6, 9 and 10, considering that the surface of the briquette 5, which contacts with the workpiece 2, is easily worn after long-term use, so that the flatness of the adjusted workpiece 2 is deviated, it is necessary to periodically check the surface flatness of the adjusted workpiece 2, and in order to facilitate checking the surface flatness of the workpiece 2, the utility model further designs a distance sensor 7, wherein at least two distance sensors 7 are provided and are respectively installed at two sides of the briquette 5; the sensing ends of the two distance sensors 7 respectively detect different parts of the workpiece 2.

Specifically, when in use, two distance sensors 7 are started, and detection light emitted by the two distance sensors 7 irradiates the surface of the workpiece 2, so that two distance values are obtained through detection;

when the pressing block 5 is positioned at the first position, if the workpiece 2 is not installed in place, the surface of the workpiece 2 is inclined, and the two distance sensors 7 detect that the distance values detected by the surface of the workpiece 2 are different;

when the pressing block 5 is in the second position, the pressing block 5 contacts and presses the workpiece 2, so that the surface of the inclined workpiece 2 can be adjusted to be in a correct position; normally, the distance values detected by the two distance sensors 7 should be equal at this time; if the two distance values have larger deviation, the fact that the bottom surface of the pressing block 5 is not in contact with the surface of the workpiece 2 is proved, the surface of the workpiece 2 cannot be flattened, and at the moment, the distance sensor 7 can feed back signals to prompt a user to operate again or check the whole condition of the pressing block 5.

In summary, the two distance sensors 7 are designed on the pressing block 5 and used for detecting the plane height difference of the adjusted workpiece 2, so that whether the surface flatness of the workpiece 2 meets the standard is detected; the user can find out the existing problems according to the detection result.

It should be noted that, in order to provide a feedback signal for a user conveniently, the two distance sensors 7 can be externally connected with a display and a buzzer, the distance values measured by the two distance sensors 7 can be displayed on the display, and when the two distance values are different, the buzzer sounds; because such techniques are relatively existing, the specific principles thereof will not be elaborated upon in the present disclosure.

Referring to fig. 2, 6, 9 and 10, both sides of the pressing block 5 are provided with a fixing frame 51 and a through hole 52; the two distance sensors 7 are vertically mounted on the corresponding fixing frames 51, respectively, and the sensing ends of the two distance sensors 7 are aligned with the corresponding through holes 52, respectively.

Wherein, the fixing frame 51 plays a role in fixing, which can enable the two distance sensors 7 to be stably arranged above the through holes 52, so as to avoid the influence on the two distance sensors 7 when the pressing block 5 presses the workpiece 2; when in use, the detection light emitted by the sensing ends of the two distance sensors 7 passes through the corresponding through holes 52 to the corresponding workpiece 2 parts to obtain two distance values, and the flatness of the surface of the workpiece 2 is judged.

Referring to fig. 2, 6, 9 and 10, further, the distance sensor 7 of the present utility model may be an optical fiber sensor, an infrared sensor, etc., and the present utility model is not limited thereto since the sensors for measuring the distance are various; the distance sensor 7 of the present utility model preferably employs an infrared sensor for cost reasons.

Referring to fig. 1, 4 and 6, considering that the downward travel of the pressing block 5 is limited, that is, the pressing block 5 has a lowest downward travel value and a highest upward travel value, the workpiece 2 with the height within a certain range of values can be generally adjusted only; when the workpiece 2 is too thin or too thick, the value exceeds the range, so that the pressing block 5 is difficult to contact the workpiece 2 or cannot be well abutted against the workpiece 2; in order to solve the problem, the utility model also comprises an adjusting mechanism 8, wherein the base 3 is provided with a chute 31 which is vertically designed, and the carrier 4 is provided with a sliding block 41 which is in sliding connection with the chute 31; the adjusting mechanism 8 is mounted on the base 3 and is in driving connection with the sliding block 41 to drive the sliding block 41 to move along the direction of the sliding groove 31.

Specifically, after the workpiece 2 is mounted on the fixture 1, the user needs to measure the thickness of the workpiece 2, if the thickness of the workpiece 2 to be processed exceeds the movable range of the pressing block 5, the adjusting mechanism 8 drives the sliding block 41 to move up or down along the direction of the sliding groove 31, so that the initial position of the pressing block 5 is changed, namely, when the pressing block 5 is in the first position, the pressing block can also be far away from or close to the workpiece 2, thereby adapting to workpieces 2 with different thicknesses, and the adaptability is strong.

For example, when the workpiece is thin, the sliding block 41 needs to be driven to move downwards along the sliding groove 31 by the adjusting mechanism 8, so that the driving mechanism 6 can well abut against the surface of the workpiece 2 when driving the pressing block to move to the second position; when the workpiece is thicker, the sliding block 41 is driven to move upwards along the sliding groove 31 by the adjusting mechanism 8, so that the problem that the workpiece 2 cannot be installed due to contact with the surface of the workpiece 2 when the pressing block 5 is in the first position is avoided.

Referring to fig. 4, 6 and 8, the adjusting mechanism 8 includes a screw 81 and a grip 82, the screw 81 is vertically and rotatably installed in the chute 31, and the screw 81 is screw-coupled with the slider 41; the first end of the screw 81 penetrates the base 3 to the outside, and the grip 82 is mounted on the first end of the screw 81.

Specifically, when in use. The user holds and rotates the holding rod 82 to drive the screw rod 81 to rotate, and then the sliding block 41 moves along the direction of the sliding groove 31, in the process, the carrying seat 4 and the pressing block arranged on the carrying seat 4 move downwards or upwards synchronously, so that the initial position of the pressing block 5 is adjusted, and the pressing block can adapt to the functions of workpieces 2 with different thicknesses.

It should be noted that the adjusting mechanism 8 may also adopt an electric driving structure such as a screw motor structure or an electric cylinder structure, and the utility model is not limited thereto since the related structures are various.

Referring to fig. 1-6, in the present utility model, a scale 3k is provided on a base 3, and the scale 3k is vertically designed and located beside a chute 31; the carrier 4 is provided with an indicator 4k corresponding to the scale 3 k.

Specifically, when in use, a user firstly measures the thickness value of the workpiece 2 to be processed, calculates the specific required movement amount of the slide block 41 by combining the movement range value of the press block 5, then drives the slide block 41 to move downwards through the adjusting mechanism 8, in the process, the number of the scale 3k corresponding to the indicator 4k is required to be observed, and after the slide block 41 moves to the required position, the slide block 41 is kept at the current position, and then the driving mechanism 6 can be started to drive the press block 5 to move from the first position to the second position to flatten the press block 5.

In summary, the cooperation design of scale 3k and indicator 4k facilitates the accurate control of the amount of movement of slider 41 of user for briquetting 5 is in work piece 2 when the second position, thereby improves the operating accuracy.

Referring to fig. 9-10, the carrier 4 is provided with a vertically designed limit groove 42, and the driving mechanism 6 comprises a driving piece 61 and a limit guide post 62; the limit guide post 62 is slidably installed in the limit groove 42, and the bottom end of the limit guide post 62 is fixedly connected with the pressing block 5; the driving member 61 is mounted on the carrier 4 and is in driving connection with the top end of the limit guide post 62, so as to drive the limit guide post 62 to move up and down along the direction of the limit slot 42, and further switch the pressing block 5 between the first position and the second position.

Specifically, in general, the briquette 5 is in the first position;

when the adjustment pressing block 5 is required to move from the first position to the second position abutting against the workpiece 2, the driving piece 61 is started to drive the limit guide post 62 to move downwards to a proper position along the direction of the limit groove 42; when the pressing block 5 presses and adjusts the flatness of the surface of the finished workpiece 2, the driving piece 61 controls the pressing block 5 to return to the first position from the second position.

In summary, according to the utility model, the cooperation design of the limit groove 42 and the limit guide post 62 can enable the pressing block 5 to be mounted on the carrier seat 4 in a vertically movable manner, and prevent the pressing block 5 from shifting in the moving process; and the driving member 61 is used for driving the limit guide post 62.

Referring to fig. 9-10, the driving member 61 generally includes an electric driving structure and a manual driving structure; the motor driving structure is adopted, so that the degree of automation is high, but the feedback sense is poor; for this purpose, a manual driving structure is adopted in the utility model; wherein the driving member 61 includes a handle 611, a driving block 612 and a transmission rod 613; the driving block 612 is provided with a first rotating hole 6121 and a second rotating hole 6122; the carrier seat 4 is hinged with the first rotating hole 6121; one end of the transmission rod 613 is hinged with the second rotating hole 6122, and the other end of the transmission rod 613 is hinged with the top end of the limit guide post 62; the handle 611 is fixedly connected with the driving block 612.
