Referring to fig. 1 and 2, fig. 1 is a schematic overall structure of an embodiment of the present invention, and fig. 2 is a schematic back structure of fig. 1.
In one embodiment of the present invention, the synchronous press-fit fixture mainly includes a mounting plate 1, a main driving assembly 2, a main driving shaft 3, a first transmission mechanism 4, a second transmission mechanism 5, a lower press-fit seat 8 and an upper press-fit seat 9.
The mounting plate 1 is a main body part of the pressing jig and is mainly used for mounting and bearing other parts.
The main driving assembly 2 is arranged on the mounting plate 1, generally on the top surface of the mounting plate 1, and the output end of the main driving assembly 2 is in power connection with the main driving shaft 3, and is mainly used for outputting rotary motion and torque to the main driving shaft 3 so as to drive the main driving shaft 3 to perform rotary motion. Meanwhile, the main driving component 2 is also the only pressing power source of the pressing jig.
The main driving shaft 3 is arranged on the mounting plate 1 and is in rotary connection with the mounting plate 1, has a degree of freedom of rotary motion and can perform rotary motion under the drive of the main driving assembly 2. Meanwhile, two ends of the main driving shaft 3 are output ends, so that two paths of output can be realized at the same time.
The first transmission mechanism 4 is specifically connected between the main driving shaft 3 and the lower pressing seat 8, the input end of the first transmission mechanism 4 is in power connection with one end of the main driving shaft 3, the output end of the first transmission mechanism 4 is in power connection with the lower pressing seat 8, and the first transmission mechanism is mainly used for converting rotary motion and torque output by the main driving shaft 3 into linear motion and push-pull force along the vertical direction and transmitting the linear motion and torque to the lower pressing seat 8 so as to drive the lower pressing seat 8 to perform vertical lifting motion.
The second transmission mechanism 5 is specifically connected between the main driving shaft 3 and the lower pressing seat 9, the input end of the second transmission mechanism 5 is in power connection with the other end of the main driving shaft 3, and the output end of the second transmission mechanism 5 is in power connection with the lower pressing seat 9, and is mainly used for converting the rotation motion and torque output by the main driving shaft 3 into linear motion and push-pull force along the vertical direction, and transmitting the linear motion and torque to the lower pressing seat 9 so as to drive the lower pressing seat 9 to perform vertical lifting motion.
As shown in fig. 3, fig. 3 is a schematic structural view of the lower press-fit seat 8 and the upper press-fit seat 9 separated from each other.
Importantly, the phase difference of the motion phase difference pi of the power conversion motion of the first transmission mechanism 4 and the second transmission mechanism 5 to the main driving shaft 3 is 180 degrees, so that the phase difference pi of the vertical lifting motion of the lower pressing seat 8 and the vertical lifting motion of the upper pressing seat 9 is also caused, that is, the motion states of the lower pressing seat 8 and the upper pressing seat 9 are synchronously reversed although the lower pressing seat 8 and the upper pressing seat 9 perform the vertical lifting motion, that is, the upper pressing seat 9 also synchronously performs the vertical descending motion when the lower pressing seat 8 performs the vertical lifting motion, and the state parameters such as the motion speed, the acceleration and the like remain the same. Meanwhile, the lower pressing seat 8 is mainly used for being abutted with the bottom surface of the workpiece, the upper pressing seat 9 is mainly used for being abutted with the top surface of the workpiece, and the lower pressing seat and the upper pressing seat are jointly used for mutually pressing and fixing the workpiece.
In this way, the synchronous pressing fixture provided in this embodiment outputs power to the main driving shaft 3 through the main driving component 2, two paths of output are simultaneously formed by using two ends of the main driving shaft 3, and meanwhile, power is split and output to the first transmission mechanism 4 and the second transmission mechanism 5, and then the power is converted by the first transmission mechanism 4 and the second transmission mechanism 5, and finally, two paths of linear motion and push-pull force along the vertical direction are formed and are respectively transmitted to the lower pressing seat 8 and the upper pressing seat 9, so that the lower pressing seat 8 and the upper pressing seat 9 are simultaneously driven to vertically lift, and the motion phase of the first transmission mechanism 4 and the second transmission mechanism 5 is different by pi, so that the motion states of the lower pressing seat 8 and the upper pressing seat 9 are ensured to keep synchronous and reverse, and the lower pressing seat 8 and the upper pressing seat 9 are driven to vertically synchronously move in opposite directions or synchronously back to each other, so that the top surface and the bottom surface of a workpiece are simultaneously pressed and fixed, and one of the lower pressing seat 8 and the upper pressing seat 9 is prevented from forming a vertical unidirectional acting force with the workpiece to generate deformation to the workpiece; in addition, the pressing power sources of the lower pressing seat 8 and the upper pressing seat 9 are the main driving component 2, only one power source is needed, and two power sources are not needed to be configured for driving respectively.
In summary, the synchronous pressing fixture provided in this embodiment can form mutual pressing on the top surface and the bottom surface of the workpiece at the same time, so as to prevent deformation caused by unidirectional acting force on the workpiece in the pressing process, and reduce the configuration cost.
In order to facilitate the power connection between the first transmission mechanism 4 and the lower pressing seat 8 and the power connection between the second transmission mechanism 5 and the upper pressing seat 9, a first output rod 6 and a second output rod 7 are additionally arranged in the embodiment. The first output rod 6 is generally inserted on the mounting plate 1 in a vertical posture, one end (top end) of the first output rod 6 is connected with the output end of the first transmission mechanism 4, and the other end (bottom end) of the first output rod 6 is connected with the lower pressing seat 8, and is mainly used for performing vertical lifting motion under the driving of the first transmission mechanism 4. Similarly, the second output rod 7 is generally inserted on the mounting plate 1 in a vertical posture, one end (top end) of the second output rod 7 is connected with the output end of the second transmission mechanism 5, and the other end (bottom end) of the second output rod 7 is connected with the upper pressing seat 9, and is mainly used for performing vertical lifting motion under the drive of the second transmission mechanism 5. And, the operation states of the first output lever 6 and the second output lever 7 are kept in the synchronous reverse direction. So set up, when main drive assembly 2 will power transmission to main drive shaft 3 on, the both ends of main drive shaft 3 drive simultaneously first drive mechanism 4, second drive mechanism 5 carries out synchronous operation, and then drive first output pole 6, second output pole 7 respectively and carry out synchronous vertical elevating movement, and when first output pole 6 carries out vertical elevating movement, second output pole 7 carries out vertical lowering movement simultaneously, vice versa to drive down pressfitting seat 8 and go up pressfitting seat 9 respectively through first output pole 6, second output pole 7 and carry out synchronous reverse vertical elevating movement.
In a specific embodiment of the mounting board 1, it is considered that in the prior art, the cylinder and the workpiece are in the same mounting environment, and power components such as the cylinder may affect environmental factors, such as heat, during operation, and may further adversely affect the workpiece (such as electronic components and the like). In this embodiment, the mounting board 1 is specifically a sealing isolation board, the main driving component 2 is specifically disposed at one side of the mounting board 1, and the lower pressing seat 8 and the upper pressing seat 9 are specifically disposed at the other side of the mounting board 1. For example, the main driving component 2 is specifically located above the mounting board 1, and the lower pressing seat 8 and the upper pressing seat 9 are specifically located below the mounting board 1, so that the power system with the main driving component 2 as a core is isolated from the pressing executing mechanisms such as the lower pressing seat 8 and the upper pressing seat 9 by using the sealing isolation board.
To facilitate the installation of the power system with the main drive assembly 2 as the core, an upper mounting beam 10 is added in this embodiment. Specifically, the upper mounting beam 10 is disposed on the top surface of the mounting plate 1 and extends vertically upward by a predetermined height, and the main driving assembly 2 is disposed on the upper mounting beam 10, such as at the top of the upper mounting beam 10. At the same time, the main drive shaft 3 is also arranged on the upper mounting beam 10 and forms a rotational connection with the upper mounting beam 10, enabling a rotational movement on the upper mounting beam 10. Typically, a boss is connected to the upper mounting beam 10, and the main drive shaft 3 is inserted into the boss. Meanwhile, the upper mounting beam 10 may be provided with a single block or two blocks, and correspondingly, the convex plate may be provided with a single block or two blocks. Of course, the remaining components of the power system described above may also be mounted to the upper mounting beam 10.
As shown in fig. 4, fig. 4 is a schematic diagram of a specific structure of the main driving assembly 2.
In a specific embodiment with respect to the main drive assembly 2, the main drive assembly 2 mainly comprises a main drive motor 21 and a decelerator 22. The main driving motor 21 is a pressing power source, and is generally mounted on the upper mounting beam 10 through a motor base. The decelerator 22 is also mounted on the upper mounting beam 10 through a base, and an output shaft of the main driving motor 21 is in power connection with an input end of the decelerator 22, and an output end of the decelerator 22 is in power connection with the main driving shaft 3. The speed reducer 22 is mainly used for reducing the speed and increasing the torque of the power output of the main driving motor 21. Meanwhile, the main driving motor 21 is usually in a vertical installation posture on the upper installation beam 10, so that the power output is facilitated, and the speed reducer 22 converts and outputs the power of the main driving motor 21 through an internal transmission mechanism so as to convert the power output into a power output in a horizontal direction, for example, power reversing conversion is performed through a worm gear transmission mechanism, a bevel gear transmission mechanism and the like.
In order to facilitate the power connection between the speed reducer 22 and the main drive shaft 3, a belt transmission mechanism is added in the embodiment. The output end of the speed reducer 22 is in power connection with the main driving shaft 3 through a belt transmission mechanism, such as a synchronous belt transmission mechanism, a flat belt transmission mechanism, a V belt transmission mechanism and the like. Specifically, the belt transmission mechanism mainly includes a driving pulley 23, a driven pulley 24, and a transmission belt 25. Wherein the driving pulley 23 is connected to the output of the reduction gear 22, and the driven pulley 24 is connected to the main drive shaft 3, and the transmission belt 25 is wound around the driving pulley 23 and the driven pulley 24. Specifically, the driving pulley 23 has a hollow shaft center and is sleeved on the output shaft of the speed reducer 22, and specifically, the driving connection between the driving pulley and the output shaft can be realized through splines and the like. Similarly, the driven pulley 24 has a hollow shaft center and is sleeved on the main driving shaft 3, and specifically, the driving connection between the driven pulley and the main driving shaft can be realized through splines and the like. Of course, the driving pulley 23 and the driven pulley 24 may be connected to the output shaft of the speed reducer 22 and the main drive shaft 3 by a coupling or the like. The belt 25 may be a synchronous belt, a flat belt, a V belt, or the like.
Further, in order to improve the transmission efficiency of the belt transmission mechanism, the present embodiment adds a pinch roller 26 to the belt transmission mechanism. Specifically, the pinch roller 26 is disposed on the upper mounting beam 10, and is mainly used for abutting against the driving belt 25, specifically, abutting against a portion of the driving belt 25 located below, so as to press and flatten the driving belt 25 upwards, and form a support, so as to prevent the driving belt 25 from sinking and deforming due to dead weight, and thus, the driving efficiency is low. Meanwhile, the pinch roller 26 may be a roller or a fixed roller.
Considering that the dimensions of the lower press-fit seat 8 and the upper press-fit seat 9 are larger, especially the width dimension is more obvious, and the first output rod 6 or the second output rod 7 can only realize single-point local driving, the vertical lifting movement state of the lower press-fit seat 8 and the upper press-fit seat 9 may be uneven or unbalanced. In this embodiment, two first output rods 6 are simultaneously provided and are respectively connected with two ends of the lower pressing seat 8 in the width direction, so as to apply force to two ends of the lower pressing seat 8 at the same time, and ensure the movement stability of the lower pressing seat 8. As for the second output lever 7, only a single one is provided in detail, but the output is performed simultaneously by the two hollow levers 71, and the both ends of the upper press-fit 9 can be simultaneously biased, which will be described later. Correspondingly, the reduction gear 22 has two synchronized outputs, and the belt drive, the main drive shaft 3 and the first drive 4 are also provided simultaneously. Specifically, both ends of the output shaft of the speed reducer 22 are output ends, and the driving pulley 23 of one belt transmission mechanism is in power connection with one end of the output shaft of the speed reducer 22, and the driving pulley 23 of the other belt transmission mechanism is in power connection with the other end of the output shaft of the speed reducer 22. Meanwhile, two main driving shafts 3 may be respectively provided on the convex plates of the two upper mounting beams 10, and the driven pulley 24 of one belt transmission mechanism is connected to one of the main driving shafts 3, and the driven pulley 24 of the other belt transmission mechanism is connected to the other main driving shaft 3. Similarly, the input end of one first transmission mechanism 4 is connected with one main driving shaft 3, and the input end of the other first transmission mechanism 4 is connected with the other main driving shaft 3; and the output end of one first transmission mechanism 4 is connected with one first output rod 6, and the output end of the other first transmission mechanism 4 is connected with the other first output rod 6.
Further, since the main driving shaft 3 and the first transmission mechanism 4 are both provided with two at the same time, it is naturally also possible to provide the second transmission mechanism 5 with two at the same time. For example, one of the second transmissions 5 has its input connected to one of the main drive shafts 3, and the other second transmission 5 has its input connected to the other main drive shaft 3. However, in this embodiment, in order to simplify the structure and improve the transmission efficiency, the second transmission mechanism 5 is only provided with a single second transmission mechanism, but the input ends of the second transmission mechanism 5 are connected with the two main driving shafts 3 at the same time, that is, the power of the two main driving shafts 3 is transmitted to the same second transmission mechanism 5 in a concentrated manner, and since the motion states of the two main driving shafts 3 are synchronous (ensured by the two ends of the output shaft of the speed reducer 22), the normal motion of the second transmission mechanism 5 is not affected, and the output can be normally overlapped.
As shown in fig. 5, fig. 5 is another view of fig. 4.
Considering that the jig needs to reset the lower press-fit seat 8 and the upper press-fit seat 9 before operation in each press-fit operation, in order to realize accurate reset of the lower press-fit seat 8 and the upper press-fit seat 9, the photoelectric sensor 11 is additionally arranged in the embodiment. Specifically, the photoelectric sensor 11 is disposed on the upper mounting beam 10, and may be specifically connected to the upper mounting beam 10 or to the housing of the speed reducer 22 by means of an sensor mounting plate, and then the photoelectric sensor 11 is mounted on the sensor mounting plate, so as to ensure that the photoelectric sensor 11 faces the driving pulley 23 in the belt transmission mechanism, so as to detect whether the rotation shaft of the main driving motor 21 rotates to a preset initial position through detecting the rotation state of the driving pulley 23, and ensure that the lower press-fit seat 8 and the upper press-fit seat 9 return to the initial positions. Generally, two photoelectric sensors 11 may be simultaneously provided, one of the photoelectric sensors 11 is used as a primary point detector of the main driving motor 21, the other photoelectric sensor 11 is used as a check point of the main driving motor 21, and the check point is used as a reference point to help the main driving motor 21 determine the rotating direction and the specific rotating angle which can be quickly reset during resetting.
As shown in fig. 6, fig. 6 is a schematic diagram of specific structures of the first transmission mechanism 4 and the second transmission mechanism 5.
In a specific embodiment of the first transmission mechanism 4, the core of the first transmission mechanism 4 is a crank block mechanism, and mainly includes a first rocker arm 41 and a first connecting rod 42. Wherein one end (inner end) of the first rocker arm 41 is connected to one end of the main drive shaft 3, for example, by a spline or the like, and the other end (outer end) of the first rocker arm 41 is connected to one end of the first link 42, and a rotational connection is formed, for example, by providing a through hole at one end of the first link 42, then installing a bearing in the through hole, and the like, connected to the other end of the first rocker arm 41; the other end of the first link 42 is connected to the end of the first output rod 6, again forming a rotational connection, such as by a pin or a bolt or the like. By means of the crank block transmission characteristic of the first transmission mechanism 4, the rotary motion transmitted to the first rocker arm 41 by the main driving shaft 3 can be converted into linear motion and output to the first output rod 6, so that the first output rod 6 is driven to perform linear reciprocating motion, namely vertical lifting motion.
In a specific embodiment of the second transmission mechanism 5, the core of the second transmission mechanism 5 is also a crank block mechanism, and mainly comprises a second rocker arm 51 and a second connecting rod 52. Wherein one end (inner end) of the second rocker arm 51 is connected to the other end of the main drive shaft 3, for example, by a spline or the like, and the other end (outer end) of the second rocker arm 51 is connected to one end of the second link 52, and a rotational connection is formed, for example, by providing a through hole at one end of the second link 52, then installing a bearing in the through hole, and the like, connected to the other end of the second rocker arm 51; the other end of the second link 52 is connected to the end of the second output rod 7, again forming a rotational connection, for example by means of a pin or a bolt or the like. By means of the crank block transmission characteristic of the second transmission mechanism 5, the rotary motion transmitted to the second rocker arm 51 by the main driving shaft 3 can be converted into linear motion and output to the second output rod 7, so that the second output rod 7 is driven to perform linear reciprocating motion, namely vertical lifting motion.
Further, considering the foregoing, the first transmission mechanism 4 may be provided in two at the same time, and the second transmission mechanism 5 need only be provided in one, but the output end of the second transmission mechanism 5 needs to be connected to the two main driving shafts 3 at the same time. Specifically, in this embodiment, two second rocker arms 51 in the second transmission mechanism 5 are specifically provided, and only one second connecting rod 52 is provided, where one end of each of the two second rocker arms 51 is respectively in power connection with the other ends of the two main driving shafts 3, and the other ends of the two second rocker arms 51 are jointly connected with one end of the second connecting rod 52 in a rotating manner, for example, a through hole may be formed in one end of the second connecting rod 52, then a bearing is installed in the through hole, and then a stub shaft with both ends extending out is installed in the bearing, so that one end of the stub shaft is in rotating connection with the other end of one of the second rocker arms 51, and the other end of the stub shaft may also be in rotating connection with the other end of the other second rocker arm 51.
To ensure that the motion states of the first output rod 6 and the second output rod 7 always keep synchronous reverse, in this embodiment, the motion track of the first transmission mechanism 4 and the motion track of the second transmission mechanism 5 are centrosymmetric with respect to the main driving shaft 3. Specifically, in the initial state, the first rocker arm 41 and the first link 42 are both in a vertically upward posture (top dead center position), and the second rocker arm 51 and the second link 52 are both in a vertically downward posture (bottom dead center position); when the main driving shaft 3 starts to rotate, the first rocker arm 41 and the second rocker arm 51 always keep central symmetry with the main driving shaft 3 as an axis, the first connecting rod 42 and the second connecting rod 52 also always keep central symmetry with the main driving shaft 3 as an axis, further, the motion phase difference pi between the first rocker arm 41 and the second rocker arm 51 is ensured, the motion phase difference pi between the first connecting rod 42 and the second connecting rod 52 is ensured, and the motion states of the first output rod 6 and the second output rod 7 are synchronously reversed.
Considering that the axial dimension of the first output rod 6 is large, the first output rod needs to extend from the upper part to the lower part of the mounting plate 1, and meanwhile, the first output rod needs to pass through the mounting plate 1 halfway, so as to ensure the stability of the lifting motion of the first output rod 6, and the first sliding bearing 12 is additionally arranged in the embodiment. Specifically, the first sliding bearing 12 is connected to the upper mounting beam 10 through a connecting plate or the like, and is mainly used for mounting the first output rod 6, so as to support the first output rod 6 and ensure the movement stability of the first output rod 6. Of course, the first output lever 6 may bypass the mounting plate 1 by a coupling or the like, instead of passing through the mounting plate 1.
Similarly, considering that the second output rod 7 is generally in a horizontal plate shape, and the second output rod 7 and the second connecting rod 52 can be connected by a hinge support or other parts, and the second output rod 7 is located above the mounting plate 1, and the upper pressing seat 9 is located below the mounting plate 1, the second output rod 7 realizes two paths of simultaneous output through two hollow rods 71. In this regard, the second slide bearing 13 is added in the present embodiment. Specifically, the second slide bearing 13 is embedded in the mounting plate 1 and maintains a vertical posture, one end (top end) of the hollow rod 71 is connected to the end of the first output rod 6 and is mounted in the second slide bearing 13, the hollow rod 71 is supported by the second slide bearing 13, the other end (bottom end) of the hollow rod 71 is connected to one end of the upper press-fit seat 9 in the width direction, and the bottom end of the other hollow rod 71 is connected to the other end of the upper press-fit seat 9 in the width direction.
Furthermore, in order to simplify the structure and reduce the size and volume of the jig, in this embodiment, the first output rod 6 and the hollow rod 71 of the second output rod 7 are nested and overlapped, specifically, the first output rod 6 penetrates through the hollow rod 71 and forms sliding connection between the two, so as to ensure that the motion state of the first output rod 6 and the motion state of the hollow rod 71 do not affect each other, and meanwhile, the internal space of the hollow rod 71 is utilized, so that the space occupation is reduced; more importantly, the embedded position of the second sliding bearing 13, the mounting position of the hollow rod 71 and the mounting position of the first output rod 6 are all the same on the mounting plate 1, so that only one mounting hole is formed in the mounting plate 1 to mount the second sliding bearing 13, no additional holes are needed, and the sealing isolation of the mounting plate 1 is improved.

For example, when the auxiliary operation component 18 adopts a positioning plate, the auxiliary operation component can be abutted with two sides of a specific component on the workpiece before the lower pressing seat 8 and the upper pressing seat 9 are pressed, so that the workpiece is automatically centered; alternatively, the auxiliary work member 18 may employ a drill or the like to drill both sides of the work piece after the work piece is pressed.
In addition, the third output rod 17 may be disposed not only in front of the lower press-fit seat 8 and the upper press-fit seat 9, but also in rear of the lower press-fit seat 8 and the upper press-fit seat 9 at the same time, so that after the press-fit operation of the workpiece is finished, the discharging direction of the workpiece may be guided by an auxiliary operation member 18, such as a guide plate, or the like, disposed on the third output rod 17 in rear.
