Description

Technical Field

[0001] This utility model relates to a grinding workstation, specifically to an automatic grinding workstation for heat-exchange graphite discs. Background Technology

[0002] Currently, after the graphite discs in heat exchange are hardened by wax impregnation, the surface is manually polished. Since the weight of the graphite discs varies from a few kilograms to tens of kilograms, manual handling is difficult. In addition, the hardness of the wax after curing is very high, making manual polishing also difficult. Especially after the wax layer is removed, the graphite surface is very soft, and it is difficult to control the smoothness and gloss of the surface during manual polishing. Therefore, the efficiency of manual polishing is relatively low, and the quality is difficult to guarantee. Utility Model Content

[0003] This invention proposes an automatic grinding workstation for heat-exchange graphite discs, aiming to solve the above-mentioned problems.

[0004] The technical solution of this utility model:

[0005] An automatic grinding workstation for heat exchange graphite discs includes a graphite grinding mechanism, which comprises a platform and grinding devices. The grinding mechanism also includes at least two support rollers, each mounted side-by-side on the platform to support the heat exchange graphite disc. At least one of the support rollers is a drive roller. There are three grinding devices in total. When the drive rollers rotate, the heat exchange graphite discs supported on the support rollers undergo automatic circular motion, and their end faces and radial faces are ground by the three grinding devices respectively.

[0006] Further refining the above technical solution, the grinding device is a floating two-axis grinding belt mechanism; during the grinding process, it can adaptively float and contact the surface of the heat exchange graphite disc, ensuring the smoothness and flatness of the heat exchange graphite disc surface, and also protecting the grinding operation mechanism from rigid impacts that affect its lifespan. At the same time, the grinding belt can be changed according to the grinding requirements, resulting in low operating costs.

[0007] Further refining the above technical solution, the support rollers are divided into two groups: one group of support rollers shares a left support seat and is located on the left, and the other group of support rollers shares a right support seat and is located on the right. The left and right support seats are mounted on the platform and adopt a closed two-axis screw guide rail running mechanism, driven by a motor to move synchronously relative to each other. The rotation center of the heat exchange graphite disc can be automatically adjusted according to the diameter of the heat exchange graphite disc, ensuring that the heat exchange graphite disc does not undergo eccentric grinding during the grinding process. The closed two-axis screw guide rail running mechanism can effectively prevent graphite powder (graphite dust has permeability and conductivity) from affecting the motor operation. At the same time, the screw guide rail has high running accuracy, high running efficiency, strong grinding load capacity, and impact resistance, ensuring the surface grinding quality requirements of the heat exchange graphite disc.

[0008] The above technical solution is further refined by connecting the support rollers in the same group as the active roller with synchronous belts and synchronous pulleys to prevent the heat exchange graphite discs supported on the support rollers from slipping.

[0009] Further refining the above technical solution, the workstation also includes a base, a transport truss frame, and a graphite transport mechanism. The transport truss frame is fixed on the base, the graphite transport mechanism is installed on the transport truss frame, and the graphite grinding mechanism is installed on the base. One position on the base is designated as the loading pallet placement area, and another position as the unloading pallet placement area. The graphite transport mechanism travels back and forth between the loading pallet placement area / unloading pallet placement area and the graphite grinding mechanism, transporting the heat exchange graphite discs from the loading pallet in the loading pallet placement area to the graphite grinding mechanism, and from the graphite grinding mechanism to the unloading pallet in the unloading pallet placement area; thus realizing the automatic loading and unloading of the heat exchange graphite discs.

[0010] To further refine the above technical solution, the graphite handling mechanism is a clamp-type compatible gripper.

[0011] Further refining the above technical solution, the graphite grinding mechanism is centered, the loading tray placement area is located in front of the graphite grinding mechanism, and the unloading tray placement area is located behind the graphite grinding mechanism; this makes loading and unloading more convenient.

[0012] The advantages of this utility model are that it has a reasonable design and simple structure, and can automatically grind the end face and radial face of the heat exchange graphite disc with good grinding effect. Attached Figure Description

Detailed Implementation

[0016] like Figure 1-2As shown, the automatic grinding workstation for heat exchange graphite discs includes a base 1, a transport truss frame 2, a graphite transport mechanism 3, and a graphite grinding mechanism 4. The transport truss frame 2 is fixed on the base 1, the graphite transport mechanism 3 is installed on the transport truss frame 2, and the graphite grinding mechanism 4 is installed on the base 1. One position on the base 1 is designated as the loading pallet placement area 5, and the other position is designated as the unloading pallet placement area 6. The graphite transport mechanism 3 travels back and forth between the loading pallet placement area 5 / unloading pallet placement area 6 and the graphite grinding mechanism 4, transporting heat exchange graphite discs from the loading pallet 7 in the loading pallet placement area 5 to the graphite grinding mechanism 3, and from the graphite grinding mechanism 3 to the unloading pallet 7 in the unloading pallet placement area 6.

[0017] The graphite grinding mechanism 4 includes a platform 4-1, grinding devices 4-2, and four support rollers 4-3. The support rollers 4-3 are arranged side-by-side in two groups. One group of support rollers 4-3 shares a left support seat 4-4 on the left, and the other group shares a right support seat 4-5 on the right. The left and right support seats 4-4 and 4-5 are mounted on the platform 4-1 and utilize a closed-loop two-axis screw guide rail mechanism 4-6, driven by a motor for synchronous relative movement. One of the support rollers 4-3 is the driving roller. The support rollers in the same group as the driving roller are connected by a synchronous belt 4-7 and a synchronous pulley 4-8.
