Description

Technical Field

[0001] This utility model belongs to the technical field of tire assembly equipment, and specifically refers to an internal support type tire gripping and lifting device. Background Technology

[0002] In automated tire assembly lines, one step involves automatically stacking tires on the line. Typically, a robotic arm inserts its end into the center of the stacked tires, provides internal support, and then retrieves the tires for placement on the assembly line.

[0003] However, in practice, many problems arise during the gripping process. For example, since tires are usually stacked, the robotic arm may grab multiple tires at the same time when it extends and grips them with an inward support, resulting in overlap when placed on the assembly line. In addition, when multiple groups of tires are gripped and stacked on the conveyor line, the stacking height of different groups of tires is not the same, and the height at which the tires fall after being gripped by the robotic arm is also not the same. This results in a large difference in the spacing between adjacent tires on the assembly line, which affects the subsequent automatic tire assembly operation. Summary of the Invention

[0004] The purpose of this invention is to provide an internal support type tire gripping and lifting device, which can effectively achieve internal support gripping of multiple tires, while ensuring that they fall into the assembly line at the same height, thus greatly improving the tire loading efficiency.

[0005] The purpose of this utility model is achieved as follows:

[0006] An internally supported tire gripping and lifting device includes an internally supported panel. Several wide pneumatic grippers are fixed to the bottom of the internally supported panel, and each wide pneumatic gripper has a support rod seat at both ends. An internal support rod is fixed to the bottom of the support rod seat. A connecting plate is fixed to the top of the internally supported panel. A sliding plate is slidably mounted above the connecting plate via several guide rods. A standard cylinder is fixed to the sliding plate to drive the sliding plate to move up and down towards the connecting plate. An adjusting plate is provided between the sliding plate and the connecting plate, sliding up and down along the several guide rods. A pressure plate corresponding to the wide pneumatic grippers is fixed to the bottom of the adjusting plate. A swing fixing seat is fixed to the bottom of the sliding plate, and a swing rod is hinged to the swing fixing seat. Swing bearings are provided at both ends of the swing rod. Upper bearing guide rail grooves and lower bearing guide rail grooves adapted to the swing bearings at both ends of the swing rod are respectively fixed to the bottom of the adjusting plate and the top of the connecting plate.

[0007] The present invention is further configured such that a lead screw is inserted through the middle of the inner support panel, and the two ends of the lead screw are respectively provided with mounting threads in different directions. There are three sets of wide pneumatic grippers. The top of the middle wide pneumatic gripper is sleeved on the middle of the lead screw, and the tops of the two wide pneumatic grippers are threaded onto the mounting threads on both sides of the lead screw through screw holes. A hand-tightening wheel coaxial with the lead screw is provided on the side wall of the inner support panel. When the hand-tightening wheel is driven to rotate, the two outer wide pneumatic grippers move towards or away from each other.

[0008] The present invention is further configured such that all three sets of wide pneumatic grippers are inclined.

[0009] The present invention is further configured such that there are three pressure plates, which correspond vertically to three sets of wide pneumatic grippers. The two ends of the bottom of the adjusting plate are fixed with movable bearing slide rails. A guide rod is fixed above the pressure plate. A guide rod fixing plate is fixed above the wide pneumatic gripper. A guide hole for the guide rod to pass through is provided on the guide rod fixing plate. The top of the guide rods above the two outer pressure plates is fixed with movable fixing plates. Movable bearings adapted to the movable bearing slide rails are rotatably mounted on the movable fixing plates. The top of the guide rod located above the middle pressure plate is fixed to the middle part of the bottom of the adjusting plate.

[0010] The present invention is further configured such that there are two sets of swing fixing seats, which are respectively fixed on the front and rear sides of the bottom of the sliding plate.

[0011] The present invention is further provided that adjustment notches are provided on the front and rear sides of the adjustment plate.

[0012] The present invention is further configured such that the number of inner support rods fixed at the bottom of the support rod seat is two, the pressure plate is in the shape of a cross, and the end of the pressure plate extends into the space between the adjacent inner support rods.

[0013] The present invention is further configured such that a limiting end is provided at the bottom of the inner support rod.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0015] 1. The tire gripping and lifting device provided by this utility model uses a standard cylinder on a sliding plate to drive the inner support panel to move up and down, and uses a wide pneumatic claw at the bottom of the inner support panel to grip the stacked tires; wherein the adjusting plate, through the linkage of the swing rod, allows the pressure plate to move up and down in the opposite direction when the inner support panel moves up and down, so that the raised tire can be pressed down by the pressure plate, so that the inner support rod only grips one tire and keeps it at the same horizontal height, so that the tires subsequently unloaded to the production line maintain the same spacing, thereby improving unloading efficiency and quality.

[0016] 2. In this utility model, a lead screw is inserted through the middle of the inner support panel to facilitate the installation of multiple sets of wide air grippers. At the same time, the opposite installation threads are used so that when the hand-tightening wheel is driven, the wide air grippers on both sides move at equal distances relative to the wide air gripper in the middle. This ensures that after the multiple sets of wide air grippers clamp the tire and unload it, they are at the same distance, which improves the subsequent tire assembly operation.

[0017] 3. The wide-type pneumatic gripper of this utility model is inclined, which allows the device to occupy less space in the front-to-back direction.

[0018] 4. Furthermore, the pressure plate provided by this utility model is designed for wide air grippers on both sides, which can be moved laterally according to the matching moving bearing track and moving bearing, so that the wide air grippers on both sides can also achieve the operation of clamping a tire by the pressure plate alone after the position is adjusted, thus ensuring the accuracy of clamping.

[0019] 5. This utility model uses two sets of swing fixing seats, which are set in the front and rear directions respectively to ensure front and rear balance and allow the pressure plate to perform normal tire pressing operation; and further, adjustment notches are set at the front and rear of the adjustment plate to ensure the normal operation of the swing rod adjustment seat.

[0020] 6. The pressure plate provided by this utility model can extend between two inner support rods, thereby occupying less space while providing stable downward pressure on the tire; the limiting end of the inner support rod can position the clamped tire to a certain extent, so that several simultaneously clamped tires are at the same horizontal height.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 2 :

[0032] An internal support type tire gripping and lifting device includes an internal support panel 1. Several wide air grippers 2 are fixed to the bottom of the internal support panel 1, and support rod seats 20 are provided at both ends of the wide air grippers 2. An internal support rod 21 is fixed to the bottom of the support rod seat 20. A connecting plate 3 is fixed to the top of the internal support panel 1. A sliding plate 4 is slidably mounted above the connecting plate 3 via several guide rods 30. A standard cylinder 40 is fixed on the sliding plate 4 to drive the sliding plate 4 to move up and down on the connecting plate. An adjusting plate 5 is provided between the sliding plate 4 and the connecting plate 3, which slides up and down along the several guide rods 30. A pressure plate 6 corresponding to the several wide air grippers 2 is fixed to the bottom of the adjusting plate 5. A swing fixing seat 41 is fixed to the bottom of the sliding plate 4. A swing rod 7 is hinged to the bottom of the swing fixing seat 41. Swing bearings 70 are provided at both ends of the swing rod 7. An upper bearing guide rail groove 50 and a lower bearing guide rail groove 31 adapted to the swing bearings 70 at both ends of the swing rod 7 are fixed to the bottom of the adjusting plate 5 and the top of the connecting plate 3, respectively.

[0033] In the specific process, it is carried out in the following manner:

[0034] The connecting plate 3 is driven up and down at the output end of the standard cylinder 40. When the connecting plate 3 moves downward, the wide grippers drive the inner support rods on both sides to clamp the stacked tires. Because the tires are stacked and the length of the inner support rods is much greater than the tire width, the number of tires clamped in this way is often relatively large. Then, the standard cylinder 40 drives the connecting plate 3 upward. The upward movement of the connecting plate 3 passes the lower side of the swing rod 7, causing the upper side of the swing rod 7 to lower. During this lowering process, the adjusting plate 5 moves downward, further driving the pressure plate 6 downward. The descending pressure plate 6 compresses a larger number of tires downward, allowing the inner support rods to clamp only a fixed number of tires according to the parameters. After all the above processes are completed, the entire device is moved for unloading, facilitating subsequent tire assembly operations.

[0035] Preferably, a lead screw 10 is provided in the middle of the inner support panel 1, and the two ends of the lead screw 10 are respectively provided with mounting threads 100 in different directions. There are three sets of wide air grippers 2. The top of the middle wide air gripper 2 is sleeved in the middle of the lead screw 10, and the tops of the two wide air grippers 2 are threaded onto the mounting threads 100 on both sides of the lead screw 10 through screw holes. A hand-tightening wheel 11 coaxial with the lead screw 10 is provided on the side wall of the inner support panel 1. When the hand-tightening wheel 11 is driven to rotate, the two outer wide air grippers 2 move towards or away from each other.

[0036] During the feeding process, the tire will undergo some dimensional changes. By using the hand-tightening wheel 11, the wide air grippers on both sides and the wide air gripper in the middle are made to have the same distance. This is achieved by using opposite mounting threads 100 and adapting certain sliding parts to allow the wide air grippers on both sides to slide.

[0037] Preferably, all three sets of wide pneumatic grippers 2 are inclined.

[0038] In the above structure, after the device clamps a fixed number of tires, it is necessary to move the entire device forward and backward or left and right. The three sets of wide air grippers 2 set at an angle can save a lot of space and provide convenience for subsequent assembly.

[0039] Preferably, there are three pressure plates 6, which correspond vertically to the three sets of wide pneumatic grippers 2. The bottom ends of the adjusting plate 5 are fixed with movable bearing slide rails 51. A guide rod 60 is fixed above the pressure plate 6. A guide rod fixing plate 22 is fixed above the wide pneumatic gripper 2. The guide rod fixing plate 22 has a guide hole for the guide rod 60 to pass through. The top of the guide rod 60 above the two outer pressure plates 6 is fixed with a movable fixing plate 61. A movable bearing 610 adapted to the movable bearing slide rail 51 is rotatably mounted on the movable fixing plate 61. The top of the guide rod 60 above the middle pressure plate 6 is fixed to the middle of the bottom of the adjusting plate 5.

[0040] In the working process of the pressure plate 6, the pressure plate 6 adapted to the wide air grippers 2 on both sides needs to be moved as well. At the same time, the adjusting plate can drive the moving pressure plate. The sliding problem can be easily solved by using the above-mentioned compatible moving bearing 610 and moving bearing slide rail 51.

[0041] It is worth mentioning that the movable bearing 610 is a deep groove ball bearing.

[0042] Preferably, there are two sets of swing fixing seats 41, which are respectively fixed to the front and rear sides of the bottom of the sliding plate 4. This improves the stability of the pressure plate during operation.

[0043] Preferably, the adjustment plate 5 has adjustment notches 52 on both the front and rear sides.

[0044] Preferably, the number of inner support rods 21 fixed to the bottom of the support rod seat 20 is two, the pressure plate 6 is in the shape of a cross, and the end of the pressure plate 6 extends into the space between adjacent inner support rods 21. Each support rod seat 20 uses two inner support rods 21 to improve the stability when supporting the tire and effectively prevent it from falling off.

[0045] Preferably, the bottom of the inner support rod 21 is provided with a limiting end. The limiting end can prevent the clamped tire from falling off.

[0046] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
