Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automatic loading and unloading devices, and in particular relates to an automatic loading and unloading tray device for an engine. Background Art
[0002] On the automobile engine assembly production line, operators are required to place the tray containing cylinder head bolts on the engine cylinder head so that operators at the next workstation can assemble the engine cylinder block and cylinder head. However, due to the heavy overall mass of the tray containing the end cover bolts, it is inconvenient for operators to move it, and the process of manually loading and unloading the tray is not easy to control. Long-term work can easily lead to quality problems such as the tray colliding with the engine cylinder block, or the end cover bolts falling into the inner cavity of the cylinder head, thus causing the engine cylinder block to be scrapped, affecting the production rhythm, and there are safety hazards in manually carrying the tray, which can easily cause scratches and pinches to operators. Utility Model Content
[0003] The utility model provides an automatic loading and unloading tray device for an engine, which aims to place end cover bolts on an engine cylinder cover in a manner of simulating manual loading and unloading trays.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] An automatic loading and unloading tray device for an engine, wherein a tray for placing and conveying an engine cylinder head is arranged on a conveyor line, and a tray containing cylinder head bolts is arranged on the tray at the downstream side of the engine cylinder head, racks are arranged on the two side stands of the conveyor line, and clamping mechanisms are provided on the racks, the clamping mechanisms connected to the lifting mechanism are driven by the lifting mechanism to perform lifting displacement, and the lifting mechanism connected to the translation mechanism is driven by the translation mechanism to perform translation displacement, and the clamping mechanisms clamp or release the tray.
[0006] In the above scheme, when the tray containing the cylinder head bolts reaches the specified position, the clamping mechanism clamps the tray, which is first lifted to the specified height by the lifting mechanism, and then translated to the specified position by the translation mechanism, and then lowered to the specified height by the lifting mechanism. The clamping mechanism releases the tray to simulate the manual loading and unloading of the tray to place the end cover bolts on the engine cylinder head. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] An automatic loading and unloading tray device for an engine is characterized in that: a tray B for placing and conveying an engine cylinder head C is arranged on a conveyor line A, and a tray D containing cylinder head bolts is arranged on the tray B and is located on the downstream side of the engine cylinder head C. A rack 1 is arranged on the two side racks of the conveyor line A, and a clamping mechanism 10 is provided on the rack 1. The clamping mechanism 10 connected to a lifting mechanism 20 is driven by the lifting mechanism 20 to perform lifting displacement, and the lifting mechanism 20 connected to a translation mechanism 30 is driven by the translation mechanism 30 to perform translation displacement, and the clamping mechanism 10 clamps or releases the tray D.
[0011] In the above scheme, there are engine cylinder head C and material tray D containing cylinder head bolts on conveyor line A, and frames 1 are arranged on the two side platforms of conveyor line A, and clamping mechanism 10 is provided on frame 1. When conveyor line A conveys engine cylinder head C and material tray D to the clamping position of clamping mechanism 10, clamping mechanism 10 clamps material tray D, and after material tray D is lifted by lifting mechanism 20, it is moved to the top of engine cylinder head C by translation mechanism 30, and then descends to engine cylinder head C. Clamping mechanism 10 releases material tray D, and then lifting mechanism 20 and translation mechanism 30 return to the waiting position, waiting for the next workpiece to arrive, that is, the whole operation process is completed by simulating manual loading and unloading of material trays.
[0012] Furthermore, the clamping mechanism 10 includes a connecting seat 11 fixedly connected to the lower part of the lifting mechanism 20, and a transverse guide rail 12 perpendicular to the transmission direction of the conveyor line A is provided on the lower seat surface of the connecting seat 11, and a left clamping jaw 13 and a right clamping jaw 14 are slidingly arranged on the transverse guide rail 12. The left clamping jaw 13 and the right clamping jaw 14 are driven by the driving unit to move toward or away from each other along the transverse guide rail 12 to clamp or release the material tray D.
[0013] Furthermore, the translation mechanism 30 includes a longitudinal guide rail 31 along the conveying direction of the conveyor line A and a movable seat 32 slidably arranged with the longitudinal guide rail 31. The movable seat 32 is fixedly connected to the upper part of the lifting mechanism 20. The movable seat 32 slides along the longitudinal guide rail 31 under the drive of the driving unit, thereby moving the lifting mechanism 20 horizontally.
[0014] Furthermore, the lifting mechanism 20 includes a vertical guide rail seat 21 and a stand seat 22 slidably arranged with the vertical guide rail seat 21. The upper end of the vertical guide rail seat 21 has an upper connecting plate 23 connected to the movable seat 32, and the lower end of the stand seat 22 has a lower connecting plate 24 connected to the connecting seat 11. The stand seat 22 moves up and down along the vertical guide rail seat 21 with the connecting seat 11 driven by the driving unit.
[0015] Preferably, the lower part of the stand 22 is connected with a driving cylinder 25, and the rod end of the piston rod 26 of the driving cylinder 25 is connected to the lower connecting plate 24. In the above scheme, before the tray D reaches the specified position, the clamping mechanism 10 needs to wait for the tray D to arrive, so the clamping mechanism 10 needs to avoid the movement path of the tray D. When the tray D reaches the specified position, the rod end of the piston rod 26 of the driving cylinder 25 is connected to the lower connecting plate 24, and the driving cylinder 25 drives the piston rod 26 to move downward by a small amplitude, so that the clamping mechanism 10 is close to the tray D, so as to facilitate the clamping operation of the tray D.
[0016] Furthermore, the claws of the left clamp 13 and the right clamp 14 are in an inverted "F" shape with their openings facing each other. The relatively arranged clamping openings of the left clamp 13 and the right clamp 14 cooperate with the clamping ears on both sides of the material tray D to clamp or release the material tray D.
[0017] Furthermore, in order to realize accurate and efficient operation of the clamping mechanism 10 , the lifting mechanism 20 , and the translation mechanism 30 , the clamping mechanism 10 , the lifting mechanism 20 , and the translation mechanism 30 are all driven by a driving unit composed of a cylinder.
