Description

Technical Field

[0001] This utility model relates to engine cylinder block processing equipment, specifically to a lifting tray mechanism for the lower cylinder block of an engine. Background Technology

[0002] Engine blocks are collected and transported on pallets after production. The surface of the pallets has many grooves for the cylinder blocks to be fitted and inserted. Over time, a lot of dust will accumulate in the grooves of the pallets. In addition to dust, metal shavings from the manufacturing process may also remain. To address this, Chinese invention patent application CN116921369A discloses a device for cleaning the inner wall of an engine cylinder block tray. This device, relating to the field of tray cleaning, solves the problem of existing cleaning devices lacking dust recovery functionality. It includes a housing with two symmetrically distributed support plates fixedly mounted at the bottom. Each support plate has a spring-loaded mechanism aligned with the tray body. A vacuum cleaner is fixedly mounted on the inner wall of the housing. A reciprocating screw is fixedly mounted on the right side of the housing, with a slider connected to the output end of the screw. An L-shaped plate is fixedly connected to the bottom of the slider, contacting the bottom of the tray body. The bottom of the housing has a roller brush mechanism and a pressing mechanism, used to clean dust from the surface of the tray body and to clean the recesses of the tray body, facilitating the suction head to draw in dirt and dust, thus achieving the effect of cleaning the inner wall of the tray body.

[0003] This invention maintains the cleanliness of the pallet mechanism by adding cleaning equipment to existing pallets. This is an additional feature that further increases the overall price of the pallet mechanism. Summary of the Invention

[0004] This utility model addresses the problem of debris accumulation in existing pallet mechanisms. Adding a cleaning mechanism would take up space and increase the cost of pallet procurement. Therefore, a lower cylinder lifting pallet mechanism using chrome-plated rods to splice together the pallet body is designed.

[0005] This utility model provides a lifting tray mechanism for the lower cylinder block of an engine, including: a tray assembly;

[0006] A guide rod is provided on the top surface of the pallet assembly, which serves as a coarse positioning tool for the workpiece.

[0007] A pallet guide rod is provided on the bottom surface of the pallet assembly to determine the lifting direction of the pallet;

[0008] A flange bushing is fitted onto the tray guide rod;

[0009] A linear cylinder is installed in the middle of the bottom surface of the pallet assembly, and the telescopic end of the linear cylinder is fixedly connected to the pallet assembly.

[0010] The tray assembly is made up of chrome-plated rods. The chrome-plated rods are cylindrical.

[0011] Preferably, the pallet assembly includes at least two parallel main support bars and at least three secondary support bars connected to the main support bars;

[0012] The guide rod is mounted on the main support rod;

[0013] Secondary support rods include at least one that intersects the center of gravity, and all secondary support rods are fixed to the primary support rods.

[0014] Preferably, the guide rod is mounted on the pallet assembly via a guide seat, which is J-shaped when viewed from above, so that the guide rod is positioned inside the pallet assembly when viewed from above.

[0015] The guide rods and guide seats are arranged in groups, including at least two, with one on each of the main support rods.

[0016] Preferably, the two ends of the secondary support rod are provided with arc grooves, and rectangular protrusions are provided in the grooves;

[0017] At the connection between the main support rod and the secondary support rod, the vertical surface of the connection is milled flat, and a rectangular countersunk hole is set laterally at the center of the vertical surface of the connection.

[0018] The rectangular protrusion of the secondary support rod is inserted into the rectangular countersunk hole of the main support rod for a mating fit.

[0019] Preferably, the secondary support rod on the outer side has two vertical surfaces at its midpoint, and the vertical surfaces are parallel to the radial surface of the main support rod.

[0020] The secondary support rod is located in the middle. The bottom surface of the rod where the midpoint is located is provided with a lifting and matching countersunk hole. The telescopic end of the linear cylinder is inserted into the lifting and matching countersunk hole, which is a rectangular hole.

[0021] Preferably, a rectangular groove is provided on the body of the main support rod, with the bottom surface of the groove being a plane. The rectangular groove is used to set the guide seat.

[0022] As a preferred embodiment, the two ends of the main support rod are named the first end and the second end;

[0023] Therefore, the distance between the secondary support rod located on the second end side and the secondary support rod located in the middle is smaller than the distance between the secondary support rod located on the first end side and the secondary support rod located in the middle.

[0024] A distance is provided between the secondary support rod located on the first end side and the vertical plane where the first end is located;

[0025] The J-shaped heads of the guide seats all point to the second end, and the hooks of the J-shapes are connected to the main support rod.

[0026] The beneficial effects of this invention are as follows: replacing the traditional flat pallet with a pallet composed of chrome-plated rods not only reduces the procurement cost of the pallet mechanism, but also eliminates the need for pallet inner wall cleaning equipment due to the less accumulating of debris from the chrome-plated rod splicing structure, further reducing the procurement cost of the pallet mechanism.
