Description

Technical Field

[0001] The utility model relates to the technical field of pressing equipment, in particular to a pressing and supporting stable mechanism. Background Art

[0002] The pressing and supporting mechanism is mainly used in the pressing assembly process to provide a supporting force opposite to the direction of the pressing force, thereby protecting the assembly structure. For example, in a common turntable type assembly mechanism, the conveying of the assembled parts is completed by the rotation of the turntable, and during the process, the inlay is inserted into the assembled parts through the pressing mechanism. Since the pressing mechanism will generate a downward pressure acting on the turntable during the inlay operation, the turntable structure is prone to deformation. Therefore, a pressing and supporting mechanism is required to support the turntable in the opposite direction to reduce the direct action of the downward pressure of the pressing mechanism on the turntable.

[0003] Currently, the common method is mainly to drive the lifting of the top block vertically by a cylinder, avoiding contact and wear between the top block and the turntable during the rotation of the turntable. When the pressing mechanism inserts the inlay, the top block is lifted to contact the turntable, so that the downward pressure of the pressing mechanism can be converted from directly acting on the turntable to acting on the top block and transmitted to the cylinder, thereby reducing the deformation of the turntable structure. However, since the downward pressure of the pressing mechanism directly acts on the cylinder, it will cause a certain degree of axial displacement of the cylinder piston rod under the action of the pressure, resulting in poor supporting stability of the turntable.

[0004] Therefore, there is an urgent need for a pressing and supporting stable mechanism to solve the above existing problems. Summary of the Utility Model

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Refer to Figures 1-4 , the present invention provides a pressing and supporting stable mechanism, including:

[0035] A base 1, with a support seat 2 fixed above the base 1, and an adjustable distance between the base 1 and the support seat 2;

[0036] A top block 3, slidably connected to the support seat 2 in the vertical direction;

[0037] A pair of connecting rods 4, relatively arranged on both sides of the top block 3, and a driving component is arranged on the support seat 2. The driving component has a driving end connected to the connecting rod 4, so that the bottom end of the connecting rod 4 can move in the horizontal direction, and the top end of the connecting rod 4 is rotatably fixed to the top block 3;

[0038] Wherein, when the top block 3 is lifted vertically to abut against the assembly mechanism, the pair of connecting rods 4 move synchronously and abut against the support seat 2 in the vertical direction.

[0039] In the present invention, by fixing the support seat 2 on the base 1, the top block 3 can slide vertically with the support seat 2 to support the assembly mechanism. And when the top block 3 abuts against the assembly mechanism, the connecting rods 4 are distributed in the vertical direction, so that the downward pressure generated by the assembly mechanism can be transmitted to the connecting rods 4 through the top block 3. By using the connecting rods 4 to abut against the support seat 2 and support the top block 3 in the vertical direction, not only can the top block 3 be lifted vertically by the connecting rods 4, but also the downward pressure of the assembly mechanism can be effectively prevented from directly acting on the driving end of the driving component along the axis direction of the output action, thus effectively alleviating the situation that the driving end of the driving component will generate axial displacement under the action of the downward pressure, realizing the improvement of the support stability of the top block 3, and further improving the support stability of the overall structure for the assembly mechanism.

[0040] In addition, there is an adjustable distance between the base 1 and the support seat 2. Since the top block 3 has a specific lifting stroke under the driving action of the connecting rods 4, by adjusting the height of the support seat 2, the top block 3 can ensure the contact effect with the assembly mechanism at the end of the stroke.

[0041] In this technical solution, the assembly mechanism is preferably but not limited to a common turntable assembly machine. Due to the characteristics of its turntable structure, there are relatively high requirements for the stability of the downward pressure support at the downward pressure assembly position. By using the top block 3 of this patent to support the turntable structure, the axial displacement of driving structures such as the cylinder 5 under the action of the downward pressure is effectively alleviated, realizing the stable support of the turntable.

[0042] Furthermore, the drive assembly includes:

[0043] A pair of cylinders 5, respectively fixed on both sides of the support base 2 and corresponding to a pair of connecting rods 4 one by one. The piston rods of the cylinders 5 extend in the horizontal direction away from the support base 2;

[0044] A transmission rod 6, connected between the cylinder 5 and the bottom end of the adjacent connecting rod 4. A push-pull block is provided at the end of the piston rod of the cylinder 5, and both ends of the transmission rod 6 are rotatably connected to the push-pull block and the connecting rod 4 respectively.

[0045] By driving one end of the connecting rod 4 to move horizontally through the piston rod of the cylinder 5 and the transmission rod 6, the connecting rod 4 rotates around the rotating end with the top block 3, adjusting the position state of the connecting rod 4, transitioning the movement of the connecting rod 4 from an inclined state to a vertical direction, and during the process, the connecting end of the connecting rod 4 is rotatably fixed to the top block 3, driving the top block 3 to lift vertically.

[0046] Furthermore, it also includes:

[0047] A first pin shaft 7. A chute is horizontally opened on the bottom side wall surface of the support base 2. The first pin shaft 7 is slidably limited in the chute and respectively penetrates through the transmission rod 6 and the connecting rod 4.

[0048] By using the opened chute and the first pin shaft 7 for sliding limit connection, the lifting stroke of the top block 3 is controlled. Referring to Figure 1 、 Figure 2 , when the top block 3 is not in contact with the assembly mechanism, the first pin shaft 7 is located at the inner end of the chute relative to the support base 2. When the first pin shaft 7 moves along the chute to the outer end, the connecting rod 4 rotates to the vertical direction and drives the top block 3 to lift vertically. The top block 3 abuts against the assembly mechanism, and the connecting rod 4 transmits the downward pressure vertically to the first pin shaft 7, and the first pin shaft 7 then cooperates with the chute to transmit the downward pressure to the support base 2.

[0049] And referring to Figure 4The technical solution arranges the cylinder in the horizontal direction and limits the rotation of the connecting rod through the slide groove and the first pin shaft. When the first pin shaft moves to the outermost side of the slide groove, the cylinder can continuously provide output force to make the first pin shaft counteract the slide groove. Then, when the top block 3 transmits the downward pressure, the output action of the cylinder can effectively realize the stability of the vertical support of the connecting rod, thereby improving the supporting effect of the top block. Compared with the traditional method of vertically arranging the cylinder, it can avoid the continuous output force provided by the cylinder from acting on the turntable structure, causing the lifting force formed from below to damage the turntable structure.

[0050] Furthermore, a plurality of transmission rods 6 are provided, and both ends of any first pin shaft 7 extending out of the slide slot are connected with a transmission rod 6 .

[0051] By respectively arranging two transmission rods 6 on both sides of the first pin shaft 7, the stability of the driving action of the transmission rod 6 is improved.

[0052] Furthermore, the push-pull block is a top plate 8 , which is fixed to the piston rod of the cylinder 5 , and a second pin shaft 9 is penetrated through the top plate 8 along the width direction, and both ends of the second pin shaft 9 are respectively connected to the transmission rod 6 .

[0053] The top plate 8 and the second pin shaft 9 are rotatably fixed, and the second pin shaft 9 is fixed to the piston rod of the cylinder 5. The transmission rods 6 are respectively connected to the two ends of the second pin shaft 9. When the piston rod of the cylinder 5 moves in the horizontal direction, the transmission rod 6 drives the connecting rod 4 to move in the horizontal direction.

[0054] Furthermore, it also includes:

[0055] A pair of third pin shafts 10 are provided. The pair of third pin shafts 10 are respectively connected to both sides of the top block 3 and correspond to a pair of connecting rods 4 one by one. A groove is provided on the bottom surface of the top block 3. The third pin shaft 10 passes through the groove along the width direction of the top block 3. The connecting rod 4 is penetrated on the third pin shaft 10, and the connecting rod 4 can be rotatably fixed in the groove.

[0056] The third pin shaft 10 penetrates the top block 3 and the connecting rod 4 is connected in the groove, so that the connecting rod 4 and the top block 3 are rotatably fixed.

[0057] Furthermore, it also includes:

[0058] The adjusting pad 11 is fixedly connected to the top surface of the base 1 , and the supporting seat 2 is fixedly connected to the top surface of the adjusting pad 11 . The adjusting pad 11 has an adjustable thickness so that an adjustable distance is provided between the base 1 and the supporting seat 2 .

[0059] The adjustment pad 11 is composed of flat gaskets of different thicknesses. According to the distance between the top block 3 and the assembly mechanism when it is lifted to the highest position, the adjustment pad 11 of corresponding thickness is selected. The adjustment pad 11 is fixed between the base 1 and the support seat 2 to adjust the distance between the support seat 2 and the base 1, and the top block 3 is against the assembly mechanism, and the connecting rod 4 maintains a vertically distributed position.

[0060] Furthermore, the support seat 2 is fixedly connected to limit plates 12 on both sides along the length direction, the limit plates 12 are distributed vertically, and the top block 3 is slidably connected between the two limit plates 12 and is in sliding contact with the limit plates 12 .

[0061] The limiting plate 12 is used to limit the top block 3 so that the top block 3 slides in the vertical direction and the sliding stability of the top block 3 is improved.

[0062] The working principle of the downward pressure support stabilization mechanism of the utility model:

[0063] Taking the turntable assembly machine as an example, the base 1 is fixed to the top surface of the machine platform and is located directly below the turntable's downward assembly position. The cylinder 5 is started to lift the top block 3 to the highest point, and the distance between the top block 3 and the turntable is measured. The adjustment pad 11 of corresponding thickness is selected according to the distance, and the support seat 2 is fixed to the base 1 through the adjustment pad 11.

[0064] During the operation of the assembly mechanism, when the turntable rotates, the piston rod of the cylinder 5 retracts, and the transmission rod 6 drives the connecting rod 4 to move in the opposite direction, so that the connecting rod 4 tilts and drives the top block 3 to descend, thereby avoiding the top block 3 from contacting the turntable and causing wear. When the turntable stops and starts to press down for assembly, the piston rod of the cylinder 5 is pushed out, and the transmission rod 6 pulls the connecting rod 4 to a vertical position. At this time, the first pin shaft 7 abuts against the outer end of the slide slot, and the top block 3 is lifted and close to the turntable, and the inlay is installed from the bottom into the assembly part of the turntable assembly station. In this process, the downward pressure is transmitted to the top block 3 through the turntable, and the top block 3 transmits the downward pressure to the first pin shaft 7 through the connecting rod 4. The first pin shaft 7 is fixed to the slide slot, so that the downward pressure is supported by the support seat 2. Compared with the traditional technology, the downward pressure is directly borne by the piston rod of the cylinder 5, which effectively improves the support stability.
