Abstract
The utility model relates to a linear guide rail pair with transitional pieces. The linear guide rail pair comprises balls and a sliding block in which a ball track is arranged, wherein two ends of the sliding block are provided with reversers for making the balls reverse and circulate in the ball track. The linear guide rail pair is characterized by comprising elastic ball track transitional pieces; the elastic ball track transitional pieces are arranged at the joint of reverse ball tracks in the reversers and the ball track in the sliding block; and the elastic ball track transitional pieces are connected between the sliding block and each ball track of each direction reverser in a flexible barrier-free mode, so that the steel balls smoothly circulate, and noise is reduced.
Description
Technical field
The utility model relates to a kind of linear guide pairs with transition piece.
Background technique
Along with the development of Modern Manufacturing Technology, so that traditional development along with Modern Manufacturing Technology, so that huge variation has occured traditional manufacturing industry, Numeric Control Technology, electromechanical integration and industrial robot have obtained using more widely aborning.Location accuracy, guiding accuracy and the feed speed of mechanical transmission mechanism are improving constantly simultaneously, make traditional guide mechanism that great change occur.Since beginning commercialization in 1973, linear rolling guide has replaced traditional sliding straight guide rail gradually with its exclusive characteristic, is widely used in industrial production.Adapted to machinery now for highi degree of accuracy, high-speed, energy saving and the requirement of shortening product development cycle, be widely used in the machinery that various heavy combination working machine tools, numerical control machine tool, highi degree of accuracy electrodischarge cutting machine, grinding machine, industrial robot and even general industry use.At present, the manufacturer that produces linear rolling guide abroad mainly concentrates on the U.S., Britain, Germany and Japan and other countries.Domestic manufacture view at linear rolling guide also is in the starting stage.In the prior art, ball from the raceway of slide block enter reverser turn to raceway the time, can produce a large amount of noises; So how to make raceway is connected smoothly between slide block and the reverser, so that reduces the technical barrier that noise is related domain.
The model utility content
The technical problems to be solved in the utility model provides and a kind ofly is suitable for making each raceway of slide block and retainer to be connected smoothly, reduces the linear guide pairs of noise.
In order to solve the problems of the technologies described above, the utility model provides a kind of linear guide pairs with transition piece, comprising: ball, in establish the slide block of raceway, described slide block two ends are respectively equipped be used to making described ball turn to the reverser of circulation in described raceway; Characterized by further comprising: elasticity raceway transition piece, described elasticity raceway transition piece are located at the joint (namely going back to the hole of bead) that turns to the raceway in raceway and the described slide block in the described reverser.
Further, the stability of having slided in order to have improved slide block, described slide block both sides respectively establish with described reverser in respectively turn to the raceway to match upper and lower two groups of raceways; Each elasticity raceway transition piece is positioned at homonymy raceway and the described joint that respectively turns to raceway, and by Flexible Connector serial connection, to consist of elasticity transition assembly; Respectively be provided with the groove that is suitable for holding described elasticity transition assembly in described first, second reverser.
Further, the raceway that respectively turns in the noise that produces when turning in order to reduce ball and the described area of contact that turns between the raceway, to reduce ball, described reverser is Gothic duplex circular ares profile race.
Technique scheme of the present utility model has the following advantages compared to existing technology: (1) described elasticity raceway transition piece forms flexible accessible the connection between each raceway of slide block and reverser, in order to the smooth and easy circulation of steel ball, reduces noise; (2) the described raceway that turns to is Gothic duplex circular ares profile race, reduces ball and the described area of contact that turns between the raceway, the noise of generation when reducing ball and turning to.
Description of drawings
For content of the present utility model is more likely to be clearly understood, below the specific embodiment and by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein
Critical piece structural representation when Fig. 1 is linear guide pairs inversion of the present utility model;
Fig. 2 is assembly structure schematic representation of the present utility model;
Fig. 3 is the structural representation of elasticity transition assembly of the present utility model;
Fig. 4 is Gothic duplex circular ares profile race sectional view of the present utility model.
Embodiment
The present invention is described in detail below in conjunction with drawings and Examples:
See Fig. 1-3, a kind of linear guide pairs with transition piece comprises: ball 4, in establish the slide block 6 of raceway, described slide block 6 two ends are respectively equipped be used to making described ball 4 turn to the reverser 3 of circulation in described raceway; Characterized by further comprising: elasticity raceway transition piece 10-1, described elasticity raceway transition piece 10-1 is located at the joint (being also referred to as go back to the hole of bead) that turns to the raceway in raceway and the described slide block 6 in the described reverser 3, and this elasticity raceway transition piece 10-1 can use separately.The material selection of described elasticity raceway transition piece 10-1 can be than the elastic material of the material softer of described reverser; Described elasticity raceway convergence piece is also referred to as elasticity raceway transition piece, elasticity raceway connector loop or elasticity raceway transition ring.
Described slide block 6 both sides respectively establish with described reverser 3 in respectively turn to raceway to match upper and lower two groups of raceways; Each elasticity raceway transition piece 10-1 is positioned at homonymy raceway and the described joint that respectively turns to raceway, and by Flexible Connector serial connection, to consist of elasticity transition assembly 10; Respectively be provided with the groove that is suitable for accordingly holding described elasticity transition assembly 10 in the described reverser 3.For the ease of putting into the groove of described elasticity transition assembly 10, the elastic material of described elasticity transition assembly 10 is softer than the elastic material of described reverser.
Described reverser adopts nylon or engineering plastics.
See Fig. 4, the raceway that respectively turns in the described reverser 3 is Gothic duplex circular ares profile race.
Gothic duplex circular ares profile race: being shaped as of the rolling surface of steel ball " some contact " structure, employing with the steel ball circular arc ditch of approximate curvature directly, form " Gothic shape " ditches (Gothic) with two circular arc ditches.Its reason is, during the point contact, load rating is little, and single circular arc ditch is when axle direction bears loading, and point of contact is mobile easily, and feed accuracy is bad, and axial stiffness also reduces.
Obviously, above-described embodiment only is for the utility model example clearly is described, and is not to be restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
