[0004] The working principle and method of the reciprocating impact roadheader are different from those of the drill-mill type roadheader. If the drive shaft of the drill-mill type roadheader is arranged along the longitudinal direction of the rocker arm, the impact power box is easy to collide with the spline shaft during telescopic and / or rotary impact. , spline sleeves and other transmission components cause breakage damage, which increases the difficulty of manufacturing and / or cumbersome installation, and increases the failure rate of equipment

Abstract
A method and device for converting rotary motion to reciprocating percussion motion. The device comprises a machine body (4), a travel portion (7), and a reciprocating percussion portion (5). The reciprocating percussion portion (5) comprises a percussion drive mechanism (2), a rocker arm (6), and a percussion head (1). The percussion drive mechanism (2) comprises a percussion power source member (11), a transmission component, and a crankshaft (10). The percussion power source member (11) comprises a motor, and the motor comprises a power output shaft (14). The transmission component comprises a power gear (13) and a transmission gear (12). The power gear (13) is mounted on the power output shaft (14). The transmission gear (12) drives the crankshaft (10). The transmission component comprises a transmission shaft. The power output shaft (14) is perpendicular to the rocker arm (6), and is parallel to the transmission shaft and the crankshaft (10) so that the transmission gear (12) drives the crankshaft (10) to convert rotary motion to reciprocating motion; or the power output shaft (14) is parallel to the rocker arm (6), the crankshaft (10) is driven to convert rotary motion to reciprocating motion after the power direction is changed by a power bevel gear and a transmission bevel gear. The crankshaft (10) drives the percussion head (1) to perform reciprocating percussion. The travel portion (7) drives the machine body to travel. The machine body (4) drives the reciprocating percussion portion (5) to move and work continuously. The device applies to the mining field or mechanical engineering field, and has advantages such as strong structural strength and a small amount of maintenance.
Description
technical field [0001] The invention belongs to the field of machinery, and is especially applicable to a method for converting rotary motion into reciprocating impact motion equipment in the field of mining or construction machinery and the equipment for converting rotary motion into reciprocating impact motion for implementing the method. Background technique [0002] The drive shaft of the existing drilling-milling-cutting type roadheader is arranged longitudinally along the rocker arm, so that the drilling-milling-cutting head is easy to cause damage to the transmission parts such as the spline shaft and the spline sleeve when the drilling-milling cutting head expands and rotates, and the motor or the deceleration After the machine is damaged, the rocker arm must be disassembled in many places for maintenance. The maintenance is difficult, labor-intensive, time-consuming, and difficult to assemble. In the maintenance and disassembly, it is easy to cause damage to undamage...
