In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.
In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1 to 11, the upper press-fit jig of the present invention includes: the weight pressing mechanism comprises an upper pressing mechanism 1, a weight pressing mechanism 2 and an electric control mechanism 3, wherein the upper pressing mechanism 1 comprises a heating piece 11, the weight pressing mechanism 2 is installed on the upper pressing mechanism 1 and used for applying pressure to the upper pressing mechanism 1, the electric control mechanism 3 is installed on the weight pressing mechanism 2, the electric control mechanism 3 comprises an electric control box 31, the electric control box 31 is electrically connected with the heating piece 11, and the electric control box 31 can be turned over along one side of the weight pressing mechanism 2.
The heating element 11 is arranged in the upper pressing mechanism 1, so that the upper pressing mechanism 1 has a heating function, the heating element 11 needs to be regulated and controlled by the electric cabinet 31, the whole pressing mechanism is arranged in the equipment, other parts such as a conveying rail and a mechanical arm are arranged in the equipment, in order to prevent the electric cabinet 31 from interfering with other parts, the electric cabinet 31 is preferably arranged above the weight pressing mechanism 2, however, in actual practice, the weight is required to be replaced according to the process to change the application pressure, and the electric cabinet 31 is arranged on the weight pressing mechanism 2, so that the weight is inconvenient to replace. Therefore, the electric cabinet 31 is designed to be overturned, so that the quick disassembly and replacement of weights are realized.
In other words, the improvement of the present invention is not required to add only the heating element 11, but also the installation position of the electric cabinet 31 and the convenience of weight replacement are considered. Based on the above, the upper pressing jig provided by the invention has a heating function and can realize quick disassembly and replacement of weights.
For example, the electric control mechanism 3 further includes: the two supporting pieces 32, the two supporting pieces 32 are respectively connected with the left end and the right end of the electric cabinet 31, the supporting pieces 32 are connected with the weight pressing mechanism 2, and the rear side of the electric cabinet 31 is hinged with the weight pressing mechanism 2 (for example, hinged through a hinge). When the electric cabinet 31 is in a normal state, the supporting member 32 is in a compressed state; when the electric cabinet 31 is in the flipped state, the support 32 is in the unfolded state. The support 32 can maintain stability of the electric cabinet 31 when the electric cabinet 31 is turned over. For example, the support 32 includes: the weight pressing mechanism comprises a first connecting block 321, a second connecting block 322, a first connecting rod 323 and a second connecting rod 324, wherein the first connecting block 321 is fixedly connected with an electric cabinet 31, the second connecting block 322 is fixedly connected with a weight pressing mechanism 2, one end of the first connecting rod 323 is movably connected with the first connecting block 321, the other end of the first connecting rod 323 is movably connected with one end of the second connecting rod 324, and the other end of the second connecting rod 324 is movably connected with the second connecting rod 322. Like this, support piece 32 can follow the upset change state of electric cabinet 31 for electric cabinet 31 upset back is more stable, can not influence the dismantlement of weight.
For example, the front end of the electric cabinet 31 is provided with a temperature control instrument 311 and a handle 312, the temperature control instrument 311 is located at one side of the handle 312, the electric cabinet 31 is electrically connected with the heating element 11, and the temperature control instrument 311 can set the heating temperature and monitor the real-time temperature. The right side of electric cabinet 31 is equipped with boat type switch 313 and supply socket 314, and the position that boat type switch 313 is located is equipped with switch guard plate 315, and switch guard plate 315 can protect boat type switch 313, prevents other parts from pressing boat type switch 313 carelessly and closing electric cabinet 31. The electric cabinet 31 can also control the opening and closing of the heating element 11. If the product technology requires simultaneous heating by pressing up and down, the heating element 11 can be turned on; if the process only requires pressing and heating, the heating element 11 can be closed, so that the process requirements of different products can be met, and the universality of the hot pressing jig is improved. The rear side of the electric cabinet 31 is provided with a cable fixing structure 316 (including a cable fixing block and a drag chain), which can fix and arrange the power lines and the connecting lines. The bottom surface of electric cabinet 31 still is equipped with spherical door knob 317, when electric cabinet 31 will resume normal condition (will overturn electric cabinet 31 back), spherical door knob 317 can play the cushioning effect, prevents that the dynamics of electric cabinet 31 upset from being too big and damaging weight pressing mechanism 2.
The conventional weight pressing mechanism 2 generally consists of an upper fixing plate, a lower fixing plate, a weight rod and weights, wherein the weight rod penetrates through the upper fixing plate and the lower fixing plate, and the weights are sleeved on the weight rod and are positioned between the upper fixing plate and the lower fixing plate. The conventional weight pressing mechanism 2 is not provided with an electric cabinet, so that the weight can be replaced only by detaching the upper fixing plate when the weight is replaced. In the present invention, the electric cabinet 31 is installed above the weight pressing mechanism 2, so that the weight pressing mechanism 2 needs to be improved to realize the weight quick-release function.
For example, the weight pressing mechanism 2 includes: the two upper mounting plates 22 are respectively connected with two ends of the lower mounting plate 21, the quick release plate 23 is positioned between the two upper mounting plates 22, and the quick release plate 23 is clamped with the upper mounting plates 22. The upper mounting plate 22 serves as a fixing and connecting function. The support 32 is coupled to a side of the upper mounting plate 22 (i.e., the second connection block 322 is fixed to a side of the upper mounting plate 22). The upper mounting plate 22 and the lower mounting plate 21 are fixedly connected through a support column 28, and two ends of the lower mounting plate 21 are mounted on the upper pressing mechanism 1 through mounting seats 29. That is, in use, the lower mounting plate 21 and the two upper mounting plates 22 are stationary and the quick release plate 23 is removable. After the electric cabinet 31 is designed to be reversible, the upper fixing plate can be detached. However, in consideration of stability of the electric cabinet 31 after overturning, the two ends of the supporting member 32 need to be fixed, otherwise, even if the electric cabinet 31 overturns, when the weight is replaced, if the electric cabinet 31 is carelessly touched, the electric cabinet 31 can be overturned back, so that workers can be hit, and replacement efficiency can be affected. Based on the above, the invention adopts the design of the two upper mounting plates 22 and the quick-release plate 23, and the quick-release plate 23 is clamped with the upper mounting plates 22, so that on one hand, the connection of the supporting piece 32 can be facilitated, and the stability of the electric cabinet 31 after overturning is ensured; on the other hand, the weight can be replaced by detaching the quick release plate 23, which is beneficial to improving the replacement efficiency.
The quick release plate 23 and the upper mounting plate 22 are designed to be clamped for quick release without screwing or other operations. However, the snap-fit design also allows for the quick release plate 23 not to come loose during the hot pressing operation. For example, the upper mounting plate 22 is provided with a movable pressing block 24, and the quick release plate 23 can be fixed or detached by moving the movable pressing block 24. One end of the movable pressing block 24 is rotatably connected with the upper mounting plate 22, that is, the movable pressing block 24 can rotate on the plane where the upper mounting plate 22 is located with one end of the movable pressing block 24 as a fulcrum. When the movable pressing block 24 is arranged in the left-right direction, the other end of the movable pressing block 24 can press the quick release plate 23, so that the stability of the quick release plate 23 is improved. When the movable pressing block 24 is arranged in the front-rear direction, the movable pressing block 24 is not in contact with the quick release plate 23, and at this time, the quick release plate 23 can be easily detached. When the quick release plate 23 is removed, the weight can be directly replaced.
For example, the end of the quick release plate 23 is provided with a first step 231, the end of the upper mounting plate 22 near the quick release plate 23 is provided with a second step 221, and the first step 231 is connected to the second step 221 in a matching manner. Specifically, the length of the portion of the quick release plate 23 above the first step 231 is greater than the length of the portion below, and the length of the portion of the upper mounting plate 22 above the second step 221 is less than the length of the portion below. Thus, when the quick release plate 23 is mounted to the upper mounting plate 22, the first step 231 and the second step 221 are engaged, the first step 231 is up, and the second step 221 is down. Thus, when the movable press block 24 is released, the quick release plate 23 can be detached by only lifting the quick release plate 23 upward. The second step 221 can be engaged with the quick release plate 23, and also can support the quick release plate 23.
For example, the weight pressing mechanism 2 further includes: weight bar 25 and weight 26, weight bar 25 run through mounting panel 21 and quick detach board 23 down, and weight 26 cover is established on weight bar 25 and is located between mounting panel 21 and the quick detach board 23 down. The upper end of the weight bar 25 penetrates through the quick release plate 23, and the lower end of the weight bar 25 penetrates through the lower mounting plate 21, so that after the quick release plate 23 is detached, the number of weights 26 on the weight bar 25 can be increased or reduced to adjust the pressure applied to a product. The lower end of the weight rod 25 is spherical and abuts against the upper pressing mechanism 1 to transmit pressure.
For example, the upper mounting plate 22 is further provided with a limiting post 27, and the height of the limiting post 27 is greater than that of the movable pressing block 24. When electric cabinet 31 is in normal condition, the bottom surface and the spacing post 27 contact of electric cabinet 31, and spacing post 27 can play the effect of supporting electric cabinet 31 promptly, can play spacing effect when electric cabinet 31 overturns back again, prevents that the angle that electric cabinet 31 overturns back is too big and bump movable briquetting 24.
For example, the upper press-fit mechanism 1 includes: the upper base plate 12 and the pressure guide rod assembly 13, the pressure guide rod assembly 13 runs through the upper base plate 12, the lower end of the pressure guide rod assembly 13 is connected with the heat insulation plate 14 and the heat conduction plate 15 in sequence, and the heating element 11 is embedded in the heat conduction plate 15. The weight pressing mechanism 2 is mounted on the upper base plate 12, and the lower end of the weight rod 25 abuts against the upper end of the pressure guide rod assembly 13.

The guide rod 133 includes a vertical portion 1331 and a horizontal portion 1332, the vertical portion 1331 and the horizontal portion 1332 are fixedly connected, the upper end of the vertical portion 1331 is connected with the upper limiting plate 132, and the horizontal portion 1332 is connected with the heat insulation plate 14. When the lower surface of the upper limiting plate 132 contacts with the upper substrate 12, a gap 18 is formed between the upper surface of the horizontal portion 1332 and the upper substrate 12, and the gap 18 is a lifting stroke of the pressure guide rod assembly 13 during pressing. The horizontal portion 1332 may be sized to cover the product, depending on the size of the product.
The heating element 11 (for example, a cartridge heater) is disposed in the heat conducting plate 15, the heat conducting plate 15 is connected to the heat insulating plate 14, and the heat conducting plate 15 can uniformly conduct the heat generated by the heating element 11. The heat shield 14 can prevent the pressure guide rod assembly 13 from being damaged by heat and can also prevent heat loss. The heating element 11 is connected with the electric cabinet 31, and when the electric cabinet 31 is opened, the heating element 11 starts to heat. A thermocouple 16 for monitoring temperature is also arranged in the heat conducting plate 15, and the thermocouple 16 is connected with an electric cabinet 31. The thermocouple 16 can feed back the real-time temperature of the heat-conducting plate 15 to the electric cabinet 31, namely, the temperature control instrument 311 on the electric cabinet 31 displays the real-time temperature of the heat-conducting plate 15.

The outer circumferential surface of the travel limiter 17 is further provided with a limiting portion 171, the diameter of the limiting portion 171 is larger than that of the second mounting hole 191, and the limiting portion 171 can prevent the travel limiter 17 from falling off. The depth of the first mounting hole 122 is greater than the length of the travel limiter 17 above the limiting portion 171, that is, the travel limiter 17 has a space for movement in the first mounting hole 122 under the action of a lower jacking mechanism (the jacking mechanism is used for driving the lower pressing mechanism to move upward).
In a natural state, the stroke limiter 17 makes the limiter 171 contact with the upper surface of the guide plate 19 under the action of gravity, and the maximum distance that the stroke limiter 17 can move upward at this time is denoted as H1 (H1 is designed according to a safe lifting stroke). When the upper limiting plate 132 contacts the upper substrate 12, the gap 18 is H2, and H1 is less than H2. The purpose of this design is that when the lower press-fit mechanism moves upwards under the action of the jacking mechanism, the heat conducting plate 15 starts to contact the product, the lower press-fit mechanism starts to contact the stroke limiter 17, and as the lower press-fit mechanism continues to move upwards, the stroke limiter 17 and the guide rod 133 also move upwards, and if the jacking stroke of the lower press-fit mechanism is within the safety range, the stroke limiter 17 is not active. When the lifting stroke of the lower pressing mechanism exceeds the safety range, the upper end of the stroke limiting piece 17 is already propped against the first mounting hole 122 and cannot move towards the first mounting hole any more, and at the moment, the lower end of the stroke limiting piece 17 is propped against the lower pressing mechanism, so that the lower pressing mechanism can be prevented from moving upwards continuously, and damage of products due to overpressure is prevented.
The left and right ends of the upper substrate 12 are further provided with a plurality of groups of adjusting bearings 110, and when the upper pressing jig is installed in the LidA ttach device, the upper pressing jig can be adjusted to a required position by moving the adjusting bearings 110.
The invention also provides a use method of the upper pressing jig, which comprises the following steps: when the electric cabinet 31 is used for powering on the heating element 11 and pressing, the upper pressing mechanism 1 can also heat the workpiece while applying pressure to the workpiece; when the pressure is to be regulated according to the process requirement, the electric cabinet 31 is turned back by 90 degrees, and the pressure applied by the weight pressing mechanism 2 is regulated. After the electric cabinet 31 is turned backwards by 90 degrees, the movable pressing block 24 is stirred, so that the quick-dismantling plate 23 can be freely dismantled; then, the quick release plate 23 is removed, and the number of weights 26 is increased or decreased to adjust the amount of applied pressure.
Specifically, when the electric cabinet 31 is turned backward by 90 °, the supporting member 32 is unfolded, and then the movable pressing block 24 is turned to the front-rear direction, the quick release plate 23 is detached, the weight 26 is taken out from the weight bar 25 to relieve the pressure or the weight 26 is added to the weight bar 25 to increase the pressure. After the replacement, the quick release plate 23 is assembled, and the movable pressing block 24 is turned to press the two ends of the quick release plate 23 in the left-right direction. Finally, the electric cabinet 31 is turned back again, and the supporting member 32 is restored to the compressed state. The whole replacement process is very simple, convenient and quick.
In summary, according to the upper pressing jig and the application method thereof of the present invention, on one hand, the heating function of the upper pressing mechanism 1 can be achieved; on the other hand, the quick replacement function of the weight 26 can be realized, the replacement step is simplified, and the working efficiency is improved.
