Abstract
The utility model discloses an electric grinder, comprising a machine body (18), a head housing (5) and an end cap (3). The head housing (5) is fixed on the machine body (18); the end cap (3) is fixed on the head housing (5), which (5) is provided with a transmission shaft (9) through a front bearing (10) and a rear bearing (12); one end of the transmission shaft (9) is connected with a motor output shaft (17) through a connecting sleeve (15) and the other end of the transmission shaft (9) is connected with an expanding sleeve (2) and a screw machine head (1) after passing through the end cap (3); the connecting sleeve (15) and the motor output shaft (17) on an end face of the machine body (18) are sleeved with a spring (16); the head housing (5) is correspondingly provided with rubber rings (7, 8) in interference fit with the front and rear bearings (10, 12); and the head housing (5) is sleeved with a rubber sleeve (4). With the above-mentioned structure, the electric grinder has a simple and reasonable structure, is easy to operate and use, and realizes rapid grinding and high precision.
Description
Technical field
The utility model relates to a kind of electronic hand-held tool, particularly a kind of electric mill that is used for grinding and buffing.
Background technology
Electric mill is requisite electric tools such as die industry, furniture industry, mechanical processing industry, and along with China's rapid economy development, the consumption of electric mill also constantly increases thereupon, because ground effect is good, precision is high, and liking of users extremely.The electric mill power that uses is less at present, generally below 300W, is hold by one hand when using operation, and for the ease of operation, motor output shaft also designs shorter, is characterized in one-handed performance, light flexibly.But in using operating process, have the following disadvantages: the one, because power is little, grinding speed is slow, efficient is low; The 2nd, one-handed performance is unfavorable for long working, causes that easily arm is ached, fatigue, and stock removal is difficult to control, directly influences grinding accuracy; The 3rd, because motor output shaft is shorter, can not extend into the long setting of small space, distance.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have rational product to emerge so far as yet.
Summary of the invention
In order to solve the problems referred to above that existing electric mill exists, the purpose of this utility model is further to improve said structure, and a kind of simple and reasonable, easy for operation, grinding speed is fast, precision is high electric mill is provided.
The technical scheme that its technical problem that solves the utility model adopts, it comprises body, head capsule, end cap, head capsule is fixed on the body, end cap is fixed on the head capsule, be provided with power transmission shaft by front and back bearings in the described head capsule, one end of power transmission shaft is connected with motor output shaft by adapter sleeve, and the power transmission shaft other end passes end cap and is connected with the spiral shell head with expansion set, is arranged with spring on the motor output shaft of adapter sleeve and body end face.
The corresponding rubber ring that is provided with the front and back bearings interference fit on the described head capsule.
Be arranged with gum cover on the described head capsule.
Described fore bearing is positioned on the head capsule by jump ring, and rear bearing is positioned on the head capsule by pad and jump ring.
After adopting said structure, the utility model has following advantage and effect: the one, can further improve power of motor, and power of motor can reach 520W; The 2nd, increased power transmission shaft, prolonged the active length of electric mill, can the both hands holding operation, the long working indefatigability has enlarged the processing operating radius, can stretch into the long setting of small space, distance and carry out operation; The 3rd, because the rubber ring of interference fit is set between head capsule and bearing, but the axiality of automatic straightening power transmission shaft and motor output shaft reduces the numbness that runs up and produce, and can also play heat-blocking action simultaneously, reduces the temperature on the head capsule; The 4th, the outer sheathed gum cover of head capsule scalds one's hand in the time of not only can avoiding gripping, and grips more comfortable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a decomposition texture schematic diagram of the present utility model.
1 spiral shell head wherein, 2 expansion sets, 3 end caps, 4 gum covers, 5 head capsules, 6 screws, 7 rubber rings, 8 rubber rings, 9 power transmission shafts, 10 fore bearings, 11 jump rings, 12 rear bearings, 13 pads, 14 jump rings, 15 adapter sleeves, 16 springs, 17 motor output shafts, 18 bodies, 19 bistriques.
The specific embodiment
Illustrated in figures 1 and 2, specific embodiments for the utility model electric mill, it comprises body 18, head capsule 5, end cap 3, head capsule 5 is fixed on the body 18 by screw 6, end cap 3 is fixed on the head capsule 5, pass through front and back bearings 10 in the described head capsule 5,12 are provided with power transmission shaft 9, one end of power transmission shaft 9 is connected with motor output shaft 17 by adapter sleeve 15, power transmission shaft 9 other ends pass end cap 3 and are connected with spiral shell head 1 with expansion set 2, spiral shell head 1 is threaded with power transmission shaft 9, expansion set 2 and power transmission shaft 9 sockets, bistrique is fixed on the expansion set 2 by spiral shell head 1, be arranged with spring 16 on the motor output shaft 17 of adapter sleeve 15 and body 18 end faces, spring 16 withstands adapter sleeve 15, occurs axial float when avoiding adapter sleeve 15 runnings.Described fore bearing 10 is positioned on the head capsule 5 by jump ring 11, and rear bearing 12 is positioned on the head capsule 5 by pad 13 and jump ring 14.
The corresponding rubber ring 7,8 that is provided with front and back bearings 10,12 interference fit on the described head capsule 5, can the automatic straightening power transmission shaft 9 with the axiality of motor output shaft 17, reduce the numbness that runs up and produce, can also play heat-blocking action simultaneously, reduce the temperature on the head capsule 5.Be arranged with gum cover 4 on the described head capsule 5, scald one's hand in the time of not only can avoiding gripping, and grip more comfortable.
