Description

Technical Field

[0001] The utility model relates to the field of counterweight devices, in particular to a linear rail type counterweight device for a double-bullhead spark machine. Background Art

[0002] Double-bullhead spark machine is a kind of mechanical processing equipment. Double-bullhead spark machine is mainly used for electric spark processing. Therefore, it has certain applications in the preparation of various metal molds and mechanical equipment. In the process of using the double-bullhead spark machine, the weight of the bullhead and the electrode combined can reach 300KG for load-bearing work;

[0003] China Patent Authorization Application No.: CN201320057777.2 provides a bullhead spark machine. This solution adds a counterweight with a weight close to the weight of the machine head at the rear of the bullhead machine tool, and then supports it through a chain and a pulley set, so that the bullhead and the machine head part form a structure like a balance, which greatly reduces the weight of the machine head end. During the up and down movement of the machine head, the counterweight always balances the weight of the machine head through the chain. Such a structure first makes the load of the servo motor lighter by almost 2 / 3, so a servo motor with a small torque can be selected to reduce power consumption; secondly, because the weight of the machine head is reduced, the burden on the driving belt is reduced, so the downtime caused by replacing the belt is also reduced, which reduces the cost. Thirdly, because the weight is balanced, a small ratio pulley set or a direct connection servo motor can be selected to meet the movement of the machine head. The selection of a small ratio pulley set can greatly speed up the movement speed of the Z-axis machine head.

[0004] The existing linear rail counterweight device has certain drawbacks when in use. First, the protective structure of the linear rail counterweight device is single. When the linear rail counterweight device produces shaking instability during the load-bearing process, the protective stability between the axes is not strong enough during the load-bearing operation, which affects the safety and stability of the operation of the linear rail counterweight device. For this reason, we propose a double-bullhead spark machine linear rail counterweight device. Utility Model Content
