Abstract
The utility model discloses a tennis service machine which is characterized by comprising a casing, a pallet and a sliding way. The front end of the casing is opened, the pallet is located above the casing and fixedly installed on the upper end portion of the sliding way, the sliding way extends in the casing, idler wheels are respectively arranged on an upper side and a lower side of the sliding way, idler wheel driving devices are connected onto the idler wheels, and a sliding way left adjusting device and a sliding way right adjusting device are arranged in the casing. The tennis service machine has the advantages of being simple in structure, capable of changing service speed and rotation degree of a tennis ball by controlling different rotation speeds of the two idler wheels, and capable of changing service directions of the tennis ball by adjusting a left position and a right position of a sliding way horizontal section due to the fact that the sliding way left adjusting device and the sliding way right adjusting device are arranged in the casing.
Description
Technical field
The utility model relates to a kind of service robot, relates in particular to a kind of tennis serve machine.
Background technology
Tennis is a motion that has antagonism and sight, because China's tennis is started to walk than later, the exercise of tennis at present substantially all relies on two people to white silk, makes that practitioner's arrangement of time is not free.In order to satisfy the needs of single exercise, also there are some tennis serve machines to occur in the market, they can imitate ball speed, rotation degree and the dynamics of people's service, but these tennis serve machines structure more complicated all basically.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of serve speed, direction and rotation degree and tennis serve machine simple in structure of changing.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of tennis serve machine, comprise housing, pallet and slideway, the front opening of described housing, described pallet is positioned at the top of described housing and is fixedly mounted on the upper end of described slideway, described slideway stretches in the described housing, the both sides up and down of described slideway are respectively arranged with roller, are connected with roller driving device on the described roller, are provided with slideway left and right sides adjusting device in the described housing.
Described roller driving device comprises the drive motors that is fixedly mounted in the described housing, and the driving shaft of described drive motors is fixedlyed connected with described roller is coaxial.
Described slideway comprises vertical section and horizontal segment, described vertical section is fixedly mounted in the described housing, described pallet is fixedly mounted on described vertical section upper end, fixedlys connected by soft tube connector between described vertical section bottom and the described horizontal segment.
Described roller is positioned at the both sides up and down of described horizontal segment, and described horizontal segment is provided with fluting, being partially submerged in the described fluting of described roller.
Described slideway left and right sides adjusting device comprises the driving cylinder of the left and right sides that lays respectively at described horizontal segment, and described driving cylinder is fixedly mounted in the described housing, and the driving shaft of described driving cylinder withstands on the described horizontal segment.
The lower end of described housing is set with universal wheel.
Compared with prior art, the utility model has the advantages that simple in structure, and the different rotating speeds by two rollers about the control, can change serve speed and the rotation degree of tennis, again owing to be provided with slideway left and right sides adjusting device in the housing, the serving side that can change tennis by the position, the left and right sides of adjusting the slideway horizontal segment to.
