[0003] Although the conveying chain can drive the workpiece to move under the driving of the rotary driving mechanism, the chain type conveying system still has the following shortcomings: the workpiece comprises a cylinder sleeve and a bearing sleeve, and the cylinder sleeve and the bearing sleeve need to be conveyed to a place at the same time, but the prior art cannot realize the simultaneous conveying of the cylinder sleeve and the bearing sleeve, so that two rotary driving mechanisms are needed to drive the cylinder sleeve and the bearing sleeve to move, resulting in a large cost and a large energy consumption of the rotary driving mechanism. SUMMARY

[0004] The present application provides a multi-cylinder sleeve horizontal multi-bearing sleeve universal conveyor, which solves the problem that the prior art cannot use the same rotary driving mechanism to drive the cylinder sleeve and the bearing sleeve.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: the present application discloses a multi-cylinder sleeve horizontal multi-bearing sleeve universal conveyor, which comprises a conveying frame, a first conveying chain, a first positioning tool, a second conveying chain, a second positioning tool, a driving sprocket, a driven sprocket and a rotary driving mechanism, the driving sprocket and the driven sprocket capable of rotating are installed on the conveying frame, the first conveying chain and the second conveying chain are wound around the driving sprocket and the driven sprocket, the rotary driving mechanism is installed on the conveying frame, and the output end of the rotary driving mechanism is connected to the driving sprocket; at least three first positioning tools are fixed on the first conveying chain, and the bearing sleeve is positioned on the first positioning tool; at least three second positioning tools are fixed on the second conveying chain, and the cylinder sleeve is positioned on the second positioning tool; the lengths of the first conveying chain and the second conveying chain are equal, the distances between adjacent two first positioning tools are equal, the distances between adjacent two second positioning tools are equal, and the distance between adjacent two first positioning tools is equal to the distance between adjacent two second positioning tools.

After circulating together, the first and second conveyor chains simultaneously transport the first and second positioning fixtures. The first positioning fixture positions the bearing sleeve, and the second positioning fixture positions the cylinder liner. This allows a single rotary drive mechanism to simultaneously transport both the bearing sleeve and the cylinder liner, reducing the use of multiple rotary drive mechanisms, minimizing the energy consumption required by multiple rotary drive mechanisms, and avoiding the increased costs associated with multiple rotary drive mechanisms.

Detailed Implementation

[0022] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments: like Figs. 1 to 4 As shown, this invention discloses a multi-cylinder liner horizontal multi-bearing sleeve universal transmission machine, comprising: a transmission frame 1, a first transmission chain 2, a first positioning fixture 3, a second transmission chain 4, a second positioning fixture 5, a drive sprocket, a driven sprocket, and a rotary drive mechanism 8. The transmission frame 1 is equipped with a rotatable drive sprocket and a driven sprocket. The first transmission chain 2 and the second transmission chain 4 both surround the drive sprocket and the driven sprocket. The rotary drive mechanism 8 is mounted on the transmission frame 1, and its output end is connected to the drive sprocket. At least three first positioning fixtures 3 are fixed on the first transmission chain 2, and each first positioning fixture 3 positions a bearing sleeve 91. At least three second positioning fixtures 5 are fixed on the second transmission chain 4, and each second positioning fixture 5 positions a cylinder liner 92. The lengths of the first transmission chain 2 and the second transmission chain 4 are equal. The distance between two adjacent first positioning fixtures 3 is equal, the distance between two adjacent second positioning fixtures 5 is equal, and the distance between two adjacent first positioning fixtures 3 is equal to the distance between two adjacent second positioning fixtures 5.

[0023] In this application, at least three support seats 30 are connected between the first conveyor chain 2 and the second conveyor chain 4. Each support seat has a first positioning fixture 3 and a second positioning fixture 5 fixed on it. The support seats 30 are used to position the first positioning fixture 3 and the second positioning fixture 5, so that the distance between two adjacent first positioning fixtures 3 is equal to the distance between two adjacent second positioning fixtures 5. At the same time, the support seats 30 have the function of supporting the first positioning fixtures 3 and the second positioning fixtures 5.

[0024] In order to position the output cylinder liner 92 and bearing sleeve 91, a workpiece positioning and storage device 10 is provided next to the output end of the first conveyor chain 2 and the output end of the second conveyor chain 4.

[0025] In order to transfer the bearing sleeve 91 on the first positioning fixture 3 and the cylinder liner 92 on the second positioning fixture 5 to the workpiece positioning and storage device 10, a first transfer robot 11 is provided above the first conveyor chain 2. The first transfer robot 11 is used to transfer the bearing sleeve 91 to the first storage position on the workpiece positioning and storage device 10; a second transfer robot 12 is provided above the second conveyor chain 4. The second transfer robot 12 is used to transfer the cylinder liner 92 to the second storage position on the workpiece positioning and storage device 10.

[0026] To position the bearing sleeve 91, the first positioning fixture 3 includes a first positioning seat, the top surface of which is recessed to form a circular positioning groove for the bearing sleeve 91 to be inserted. The circular positioning groove has a relatively large diameter, allowing bearing sleeves 91 of different diameters to be inserted into it.

[0027] Optionally, in order to facilitate the first transfer robot 11 to grasp the bearing sleeve 91 in the circular positioning groove, the depth of the circular positioning ring is less than the height of the bearing sleeve 91, so that the top of the bearing sleeve 91 protrudes from the circular positioning groove for the first transfer robot 11 to grasp.

[0028] To position the cylinder liner 92 in a horizontal position, the second positioning fixture 5 includes a second positioning seat, the second positioning seat having an arc-shaped groove formed on its surface, the arc-shaped groove positioning the horizontal cylinder liner 92. The arc-shaped groove can position cylinder liners 92 of different diameters.

[0029] To ensure that the cylinder liner 92 on the second positioning seat can be grasped by the second transfer robot 12, a direction detection device 13 is installed between the second transfer robot 12 and the input end of the second conveyor chain 4. The direction detection device 13 is used to adjust the alignment between the center of the cylinder liner 92 in the arc groove and the center of the second positioning seat. Adjusting the alignment between the center of the cylinder liner 92 in the arc groove and the center of the second positioning seat prevents the center of the cylinder liner 92 from deviating too much from the center of the second positioning seat, which would prevent the second transfer robot 12 from failing to surround both ends of the cylinder liner 92 during grasping, thus ensuring the second transfer robot 12 can perform the grasping action.

[0030] Optionally, the direction detection device 13 includes: an adjusting frame 131, a first lifting seat 132, an adjusting screw 133, a first detection head 134, and a second detection head 135. The adjusting frame 131 spans the first conveyor chain 2 and the second conveyor chain 4. A guide rod passes through the adjusting frame 131. The guide rod and the first lifting seat 132 can move up and down relative to the adjusting frame 131. The guide rod is fixed to the first lifting seat 132. The bottom end of the adjusting screw 133 is rotatably mounted on the first lifting seat 132. The adjusting screw 133 is threadedly connected to the adjusting frame 131. The cylinder liner 92 is equipped with a first detection head 134 and a second detection head 135 that are spaced apart from each other. The first detection head 134 is used to detect the size of the inner hole at the first end of the cylinder liner 92, and the second detection head 135 is used to detect the size of the inner hole at the second end of the cylinder liner 92. Both the first detection head 134 and the second detection head 135 are equipped with distance sensors. The distance sensors emit oblique distance light rays towards the inner wall of the inner hole at the first end or the inner wall of the inner hole at the second end of the cylinder liner 92 to detect the size of the inner hole at the first end and the inner hole at the second end. The orientation of the two ends of the cylinder liner 92 is determined by the size of the inner hole at the first end and the inner hole at the second end.

[0031] In order to store the bearing sleeve 91 and the cylinder liner 92, a first storage seat 107 and a second storage seat 108 are provided on the workpiece positioning and storage device 10. The first storage seat 107 stores the bearing sleeve 91 and the second storage seat 108 stores the cylinder liner 92.

[0032] Optionally, the top surface of the first storage base 107 supports the bearing sleeve 91. The top surface of the first storage base 107 protrudes to form a through-core. The through-core passes through the center of the bearing sleeve 91 and positions the bearing sleeve 91. The bearing sleeve 91 has a circular ring structure, so by designing the through-core, the bearing sleeve 91 can be positioned.

[0033] Optionally, the top surface of the second storage seat 108 forms a V-shaped support surface, which positions and supports the cylinder liner 92.

[0034] In order to position the cylinder liner 92 on the second storage seat 108, an alignment adjustment mechanism 100 is provided on the workpiece positioning and storage device 10. The alignment adjustment mechanism 100 is used to adjust the cylinder liner 92 on the second storage seat 108 to be aligned with the center of the second storage seat 108.

[0035] Although the center adjustment device installed in the middle of the transfer section can adjust the center of the cylinder liner 92 relative to the center of the second positioning seat to a certain extent during the transfer process, due to assembly problems of the second transfer robot 12 itself, the center of the second transfer robot 12 cannot be aligned with the center of the cylinder liner 92 after it is gripped. Therefore, the center of the cylinder liner 92 cannot be aligned with the center of the second storage seat 108 after the second transfer robot 12 grasps it. To address the above problem, the following solutions are proposed: ① When the second transfer robot 12 grasps the cylinder liner 92, there is a distance between the center of the cylinder liner 92 and the center of the second storage seat 108, and the center of the cylinder liner 92 is located between the center of the second storage seat 108 and the output end of the alignment adjustment mechanism 100; ② The alignment adjustment mechanism 100 pushes the center of the cylinder liner 92 to align the center of the cylinder liner 92 with the center of the second storage seat 108. The above solution breaks with traditional thinking (the idea of ​​precisely aligning the center of the second transfer manipulator 12 with the center of the cylinder liner 92). Instead, it directly offsets the center of the cylinder liner 92 from the center of the second transfer manipulator 12 during the gripping process, meaning the center of the cylinder liner 92 is offset from the center of the second storage seat 108. This offset positions the center of the cylinder liner 92 between the center of the second storage seat 108 and the alignment adjustment mechanism 100. It is estimated that after this offset, the cylinder liner 92 is positioned between the center of the second storage seat 108 and the output end of the alignment adjustment mechanism 100. Finally, the alignment adjustment mechanism 100 pushes the cylinder liner 92, controlling the alignment between the center of the cylinder liner 92 and the center of the second storage seat 108 through the pushing stroke of the alignment adjustment mechanism 100. In this application, the conveyor frame 1 is spanned by a gantry crane, on which a linear drive device 7 is mounted. The output end of the linear drive device 7 is connected to the first conveyor chain 2 and the second conveyor chain 4. The driving direction of the linear drive device 7 is parallel to the conveying direction of the first conveyor chain 2. The linear drive device 7 enables the first transfer robot 11 and the second transfer robot 12 to jointly grasp the bearing sleeve 91 and the cylinder liner 92, and then jointly transfer the bearing sleeve 91 and the cylinder liner 92 to the first storage seat 107 and the second storage seat 108 respectively, reducing the use of the linear drive device 7 and saving energy.

[0036] The alignment adjustment mechanism 100 includes: a push head 101, a push seat 102, a lifting cylinder 103, a movable seat 104, a second cylinder, and a fixed seat 106. The fixed seat 106 is fixed on the conveyor frame 1. The movable seat 104 is mounted on the fixed seat 106. The movable seat 104 can move relative to the fixed seat 106 in the direction of the axis of the cylinder liner 92 supported by the Y-shaped support surface. The movable seat 104 is connected to the second cylinder, which is used to push the movable seat 104 to move. The lifting cylinder 103 is fixed on the movable seat 104. The push seat 102, which can be raised and lowered, is mounted on the movable seat 104. The push head 101 is fixed on the push seat 102. The push head 101 is the output end of the alignment adjustment mechanism 100.

[0037] A blocking frame 14 is installed at one end of the conveyor frame 1 to prevent the cylinder liner 92 on the second conveyor chain 4 from falling into the gap between the conveyor frame 1 and the input end of the second conveyor chain 4. This prevents the second conveyor chain 4 from getting stuck due to the cylinder liner 92 falling off during its cyclic movement.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
