Abstract
The utility model relates to the technical field of machining equipment, particularly to a novel milling fixture for large back surfaces of elevator guide rails. The fixture comprises a fixture body, a positioning block, an upper clamping oil cylinder, a side clamping oil cylinder, a sliding table and a base, wherein the fixture body and the sliding table are connected onto the base, the positioning block, the upper clamping oil cylinder and the side clamping oil cylinder are installed on the fixture body, and an air knocking hammer and a pre-clamping oil cylinder are arranged on the sliding table. The air knocking hammer and the pre-clamping oil cylinder are connected onto the sliding table through supports, the air knocking hammer and the pre-clamping oil cylinder move along with the sliding table, through continuous high-frequency knocking by the air knocking hammer, the machined guide rails are flat in positioning and close in attachment, and the fixture is stable in structure and good in effect, so that the balance and the stability of the fixture are improved, the milling quality and the milling efficiency are greatly improved, the loss is reduced, and the quality of the guide rails is improved.
Description
Technical field
The utility model relates to machining equipment technical field, the large back side of especially a kind of Novel elevator guide rail milling fixture.
Background technology
Cage guide, as the guidance system of elevator, is the vitals that affects elevator safety and comfortableness.And the large back side milling of T-shaped guide rail is the critical process of processing T type guide rail, due to Workpiece length and processed Length Ratio in reality processing: 5000/111 ~ 193=25.9 ~ 45, workpiece center of gravity is away from fixture, cause part locating surface to be combined with fixture locating surface unreliable, cause milling to complete the large back side and part locating surface is not parallel, produce even waste product of substandard products.
Utility model content
Not firm in order to overcome existing guide rail clamp for machining location, milling is of poor quality, produces the deficiency of defect ware, and the utility model provides the large back side of a kind of Novel elevator guide rail milling fixture.
The utility model solves the technical scheme that its technical problem adopts: the large back side of a kind of Novel elevator guide rail milling fixture, comprise chuck body, locating piece, upper clamping cylinder, side clamping cylinder, slide unit and base, chuck body and slide unit are connected on base, locating piece, upper clamping cylinder and side clamping cylinder are arranged in chuck body, and slide unit is provided with air and knocks hammer and pre-clamping cylinder.
According to another embodiment of the present utility model, further comprise that air knocks hammer and is connected with slide unit by support with pre-clamping cylinder.
According to another embodiment of the present utility model, further comprise that air knocks hammer and is positioned at the rear portion of clamping cylinder and side clamping cylinder.
According to another embodiment of the present utility model, further comprise the rear portion that pre-clamping cylinder is arranged on air and knocks hammer.
According to another embodiment of the present utility model, further comprise that air knocks hammer and pre-clamping cylinder and hang on the top of locating piece.
The beneficial effects of the utility model are, on slide unit, connect air by support and knock hammer and pre-clamping cylinder, air knocks hammer and pre-clamping cylinder moves with slide unit, the continuous high frequency that knocks hammer by air impacts, make processed guide rail location smooth, laminating closely, again by after the auxiliary clamp of pre-clamping cylinder, in startup, clamping cylinder and side clamping cylinder formally clamp, Stability Analysis of Structures, respond well, effectively prevent that guide rail center of gravity is away from the laminating injustice causing, balance and the stability of fixture are improved, thereby milling quality and milling efficiency are greatly improved, reduce loss, promote the quality of guide rail.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model.
1. guide rails in figure, 2. chuck body, 3. locating piece, 4. air knocks hammer, and 5. pre-clamping cylinder, 6. goes up clamping cylinder, 7. side clamping cylinder, 8. support, 9. slide unit, 10. base.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, Fig. 2 is side view of the present utility model, the large back side of a kind of Novel elevator guide rail milling fixture, comprise chuck body 2, locating piece 3, upper clamping cylinder 6, side clamping cylinder 7, slide unit 9 and base 10, chuck body 2 and slide unit 9 are connected on base 10, locating piece 3, upper clamping cylinder 6 and side clamping cylinder 7 are arranged in chuck body 2, and slide unit 9 is provided with air and knocks hammer 4 and pre-clamping cylinder 5.Air knocks hammer 4 and is connected with slide unit 9 by support 8 with pre-clamping cylinder 5.Air knocks the rear portion that hammer 4 is positioned at clamping cylinder 6 and side clamping cylinder 7.Pre-clamping cylinder 5 is arranged on air and knocks the rear portion of hammering 4 into shape.Air knocks hammer 4 and pre-clamping cylinder 5 and hangs on the top of locating piece 3.
On slide unit 9, connect air by support 8 and knock hammer 4 and pre-clamping cylinder 5, air knocks hammer 4 and pre-clamping cylinder 5 moves with slide unit 9, when use, processed guide rail 1 is delivered in chuck body 2 by outside mode of movement, contact with locating piece 3, the first step: first start air and knock hammer 4, connect high frequency and knock processed guide rail 1, make the locating surface close contact of locating piece 3 and chuck body 2, the location that ensures processed guide rail 1 is smooth firm, restart pre-clamping cylinder 5, clamp processed guide rail 1, then start upper clamping cylinder 6 and side clamping cylinder 7, clamp processed guide rail 1.Second step: after having located, first close air and knock hammer 4, stop the knocking of processed guide rail 1, then close pre-clamping cylinder 5, unclamp processed guide rail 1, fixture completes clamping process.
The continuous high frequency that knocks hammer 4 by air impacts, processed guide rail 1 is located smooth, laminating is tight, then by after the auxiliary clamp of pre-clamping cylinder 5, in startup, clamping cylinder 6 and side clamping cylinder 7 formally clamp, Stability Analysis of Structures, respond well, effectively prevent that guide rail 1 center of gravity is away from the laminating injustice causing, balance and the stability of fixture are improved, thereby greatly improve milling quality and milling efficiency, reduced loss, promoted the quality of cage guide.
