DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The embodiment of the present application provides an automatic packing device for piston and connecting rods, thereby solving the problem that the handling of turnover boxes and the packing of connecting rods during the packing of piston and connecting rods cannot be achieved through an overall automated structure.

[0039] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0040] In the embodiment of the utility model, the piston-connecting rod automatic packing device includes: an empty box conveying mechanism, a full box output mechanism, a connecting rod loading mechanism and a clamping mechanism; the empty box conveying mechanism is used to convey the empty turnover box to the waiting clamping station; the full box output mechanism is used to convey the packed turnover box from the packing station to the unloading station; the connecting rod loading mechanism provides the clamping mechanism with the connecting rod to be packed; the clamping mechanism is used to clamp the empty turnover box from the waiting clamping station to the packing station and clamp the connecting rod to be packed from the connecting rod loading mechanism to the turnover box at the packing station; the automation of connecting rod conveying, handling, packing, turnover box handling, stacking and conveying is realized, thereby reducing the manual operation load, reducing the manual operation time, and thus reducing the labor cost.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] Example:

[0043] like Figure 1 to Figure 3 As shown, the utility model provides a piston-connecting rod automatic box packing device, which includes: an empty box conveying mechanism 10, a full box output mechanism 20, a connecting rod feeding mechanism 30 and a clamping mechanism 40;

[0044] The empty box conveying mechanism 10 is used to convey the empty turnover box to the waiting position 11;

[0045] The full box output mechanism 20 is used to transport the packed turnover box from the packing station 21 to the unloading station;

[0046] The connecting rod feeding mechanism 30 provides the clamping mechanism 40 with connecting rods to be packed;

[0047] The clamping mechanism 40 is used to clamp an empty turnover box from the to-be-clamped station 11 to the packing station 21 and to clamp the connecting rod to be packed from the connecting rod feeding mechanism 30 to the turnover box in the packing station 21 .

[0048] like Figure 1 , Figure 2 As shown, the clamping mechanism 40 includes: a gantry 41, a translation assembly 42, a vertical movement assembly 43, a support 44 and a cylinder clamp 45;

[0049] The crossbeam of the gantry 41 is located above the to-be-clamped station 11, the packing station 21 and the connecting rod loading mechanism 30, the translation assembly 42 is slidably connected to the crossbeam of the gantry 41, and the translation assembly 42 is freely slidable along the X direction under the drive of its corresponding servo motor; the vertical movement assembly 43 is slidably connected to the translation assembly 42, and the vertical movement assembly 43 is freely slidable along the Z direction under the drive of its corresponding servo motor;

[0050] The support 44 is connected to the vertical moving assembly 43 via a Y-axis slide cylinder 46 , and both sides of the support 44 are connected to a Z-axis slide cylinder 48 via an X-axis slide cylinder 47 , and the cylinder clamp 45 is installed at the bottom of the Z-axis slide cylinder 48 .

[0051] The clamping mechanism 40 drives the cylinder clamp 45 to move along the X direction through the translation component 42; drives the cylinder clamp 45 to move along the Z direction through the vertical movement component 43; the Y-axis slide cylinder 46 is used to adjust the Y-axis position of the cylinder clamp 45; the X-axis slide cylinder 47 is used to adjust the distance between the cylinder clamps 45 on both sides; the Z-axis slide cylinder 48 is used to fine-tune the height of the cylinder clamp 45, so that the clamping mechanism 40 can transport turnover boxes of various specifications and sizes from the to-be-clamped station 11 to the packing station 21.

[0052] like Figure 2 As shown, the cylinder clamp 45 is installed at the bottom of the Z-axis slide cylinder 48 through a buffer assembly, and the buffer assembly includes: a top plate 50, a bottom plate 51, a guide rod 52 and a spring 53;

[0053] The top plate 50 and the bottom plate 51 are connected and guided by a plurality of guide rods 52, and the spring 53 is sleeved on the guide rods 52 and arranged between the top plate 50 and the bottom plate 51;

[0054] The top plate 50 is fixed to the bottom of the Z-axis slide cylinder 48 , and the bottom plate 51 is fixed to the top of the cylinder clamp 45 .

[0055] Frequent use of turnover boxes will cause them to bend and deform. Although the deformed turnover boxes can still be used, the height of the stacked turnover boxes will deviate, resulting in inaccurate clamping position of the turnover boxes. Traditional clamps are difficult to solve this problem; in the present application, when the cylinder clamp 45 clamps the turnover box, the buffer component is set so that the pressure block on the clamp forms an elastic soft contact with the turnover box, and the height of the clamp is automatically adjusted. Even for deformed turnover boxes, it can ensure that the clamp is in line with the position of the notch of the turnover box, thereby achieving stable grasping of the turnover box.

[0056] like Figure 2 As shown, a cylinder clamp 49 is provided below the support 44, and a wedge-shaped clamp groove 410 is provided on the inner wall of the clamp 49, so that the clamp can stably clamp connecting rods of various specifications and sizes, thereby realizing the transportation of the connecting rod from the connecting rod feeding mechanism 30 to the turntable box on the packing station 21.

[0057] like Figure 1 As shown, the empty box conveying mechanism 10 comprises: a first conveying roller 12, a first stop pile 13 and a first push plate 14;

[0058] The end of the first conveying roller 12 is the station to be clamped 11, and a plurality of first stop piles 13 are installed at the end and side of the station to be clamped 11. A first push plate 14 is installed at a corner of the station to be clamped 11 away from the first stop piles 13. The first push plate 14 can be pushed in the direction of the angle formed by the first stop piles 13 under the drive of its corresponding cylinder, so as to realize the regularity of the turntable on the station to be clamped 11.

[0059] like Figure 1 As shown, the empty box conveying mechanism 10 further includes: a lifting baffle 15;

[0060] The lifting baffle 15 is arranged between two adjacent rollers outside the clamping station 11. The lifting baffle 15 is lifted and lowered along the Z direction under the drive of its corresponding cylinder. When the lifting baffle 15 is raised, it blocks the turnover box from entering the clamping station 11. When the lifting baffle 15 is lowered, it allows the turnover box to enter the clamping station 11.

[0061] like Figure 1 As shown, the solid box output mechanism 20 includes: a second conveying roller 22, a second stop pile 23 and a second push plate 24;

[0062] The end of the second conveying roller 22 is the packing station 21. A plurality of second stop piles 23 are installed at the end and side of the packing station 21. A second push plate 24 is installed at a corner of the packing station 21 away from the second stop piles 23. The second push plate 24 can be pushed in the direction of the angle formed by the second stop piles 23 under the drive of its corresponding cylinder, so as to realize the regularity of the turntables on the packing station 21.

[0063] A number of driving rollers and driven rollers are arranged at intervals on the first conveying roller 11 and the second conveying roller 22. Since a full box is heavier than an empty box, the conveying load of the second conveying roller 22 is larger. Therefore, the proportion of driving rollers on the second conveying roller 22 is higher than the proportion of driving rollers on the first conveying roller 11.

[0064] like Figure 1 , Figure 3 As shown, the connecting rod feeding mechanism 30 includes: a material trough 31, a third push plate 32 and a lifting pile 33;

[0065] The material trough 31 is arranged obliquely;

[0066] The side wall of the trough 31 is installed with a Y-direction cylinder 34, and the third push plate 32 is installed at the output end of the Y-direction cylinder 34, and is used to perform Y-direction preparation on the connecting rod in the trough 31;

[0067] A plurality of lifting piles 33 are arranged at intervals along the Y direction on the lower side of the material trough 31, and a through hole is opened on the bottom plate of the material trough 31 for the lifting piles 33 to pass through. The lifting piles 33 are raised and lowered under the drive of their corresponding cylinders. When the lifting piles 33 are raised, the connecting rods that have rolled to the lower side of the material trough 31 are lifted up for the clamping mechanism 40 to grasp. When the lifting piles 33 are lowered, the connecting rods in the material trough 31 roll down to the lower place for replenishment.

[0068] like Figure 3 As shown, a plurality of wedge-shaped grooves 35 are provided on the top of the lifting pile 33 , and the wedge-shaped grooves 35 are used to accommodate connecting rods, so that the lifting pile 33 can stably lift connecting rods of various specifications and sizes.

[0069] like Figure 3As shown, a connecting rod baffle 36 is provided above the material trough 31. The connecting rod baffle 36 is raised and lowered under the drive of its corresponding cylinder. When the connecting rod baffle 36 is lowered, the connecting rod is blocked from rolling down. When the connecting rod baffle 36 is raised, the blocked connecting rod rolls down to the lower side of the material trough 31 again, thereby slowing down the rolling speed of the connecting rod, reducing the impact force between the connecting rods, and avoiding damage to the connecting rod surface caused by excessive impact force.

[0070] The method for using the piston connecting rod automatic boxing device comprises the following steps:

[0071] S1. Place several layers of empty turnover boxes on the first conveying roller 12 of the empty box conveying mechanism 10; the lifting baffle 15 of the empty box conveying mechanism 10 is lowered, and the first conveying roller 12 conveys the empty turnover boxes to the waiting position 11;

[0072] S2, the first conveying roller 12 stops running, the lifting baffle 15 rises, and the first push plate 14 pushes out to sort and position the turnover box on the clamping station 11 and then returns;

[0073] S3, the clamping mechanism 40 transports the top-level turnover box on the to-be-clamped station 11 to the packing station 21, and the second push plate 24 pushes out to sort and position the turnover box on the packing station 21 and then returns;

[0074] S4, supplying the connecting rod into the inclined trough 31 of the connecting rod feeding mechanism 30;

[0075] S5, the third push plate 32 pushes out the connecting rod on the lower side of the trough 31 to prepare it in the Y direction and then returns, and the lifting pile 33 is lifted to lift the prepared connecting rod;

[0076] S6, the clamping mechanism 40 moves the lifted connecting rod to the turnover box on the packing station 21;

[0077] S7, repeat S5 to S6 several times until the turnover box is packed;

[0078] S8, repeat S3 to S7 several times until all turnover boxes are packed;

[0079] S9, the second conveyor roller 22 conveys all the packed turnover boxes from the packing station 21 to the unloading station, and moves out the turnover boxes on the unloading station, thus realizing an automatic cycle of automatic packing.

[0080] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0081] 1. In the embodiment of the utility model, the piston connecting rod automatic packing device includes: an empty box conveying mechanism, a full box output mechanism, a connecting rod feeding mechanism and a clamping mechanism; the empty box conveying mechanism is used to convey the empty turnover box to the waiting clamping station; the full box output mechanism is used to convey the packed turnover box from the packing station to the moving-out station; the connecting rod feeding mechanism provides the clamping mechanism with the connecting rod to be packed; the clamping mechanism is used to clamp the empty turnover box from the waiting clamping station to the packing station and clamp the connecting rod to be packed from the connecting rod feeding mechanism to the turnover box at the packing station; the automation of connecting rod conveying, handling, packing, turnover box handling, stacking and conveying is realized, thereby reducing the manual operation load, reducing the manual operation time, and thus reducing the labor cost. The entire device mechanism has the characteristics of ingenious design, high degree of automation, safety and reliability, simple operation, high work efficiency, and low cost.

[0082] 2. In the embodiment of the utility model, when the cylinder clamp is in the process of clamping the turnover box, the buffer assembly is set so that the pressure block on the clamp forms an elastic soft contact with the turnover box, and the height of the clamp is automatically adjusted. Even for deformed turnover boxes, it can ensure that the position of the clamp and the groove of the turnover box are consistent, thereby achieving stable grasping of the turnover box.

[0083] 3. In the embodiment of the utility model, the connecting rod feeding mechanism uses an inclined material trough to make the connecting rods automatically roll to the lower side of the trough under the action of their own gravity, and then stably provide the connecting rods to be packed through the action of the third push plate and the lifting piles; the setting of the connecting rod baffle effectively reduces the damage caused by the collision of the connecting rods.
