Abstract
The invention provides a kind of special positioning fixture connecing sapphire ingot for group.It comprises handle, screw mandrel, locating centre, support, platform, axial location base and crystal bar outer circle diameter to location gusset, and crystal bar outer circle diameter is that two pilot holes by two tommys being inserted into axial location submounts to position with it to be connected to location gusset.The present invention has group and connects crystal bar right alignment high, can reduce required reserved process redundancy, ensure working accuracy, can significantly improve following process efficiency.
Description
(1) technical field
The present invention relates to a kind of special positioning fixture, be specifically related to a kind of location unit clamp connecing sapphire ingot for group.
(2) background technology
Sapphire has excellent physical and chemical performance, is widely used in high-brightness LED substrate manufacture view at present.The preparation process of Sapphire Substrate sheet is: crystal growth, crystal bar orientation are extracted, cut the series of processes such as end polishes, crystal bar barreling, section, grinding, polishing.
Wherein crystal bar tumbling process, is improve working (machining) efficiency, needs identical to diameter but that length is relatively short sapphire ingot, carries out after group connects, then enter into the operation of cylindrical grinding in certain total length.For reducing reserved removal amount, improving circle barreling efficiency, needing accurately to dock crystal bar, ensure good right alignment.
The mode of current employing is, first the crystal bar glue group of several sections of same diameter is connect, and makes the outer circle diameter of adjacent two sections of crystal bars basically identical to location by L-square.On an end face of the crystal bar again after group connects bonding one to mid-game, observed the right alignment determined the crystal bar that mid-game and group connect by naked eyes.After confirmation, on another end face of crystal bar bonding one to mid-game, make two centers to mid-game on the same axis by a simple horizontal centring, device for exerting, and make their strong bond.The shortcoming of the method is, at the bottom of bonding efficiency, can not be ensured basically identical, be unfavorable for the processing of subsequent handling by the coaxiality deviation that group connects between crystal bar.In addition, although current method can ensure two right alignmenies to mid-game, but be not easy to ensure to the right alignment at the center of mid-game and the center of crystal bar, easily cause and add man-hour carrying out cylindrical grinding to crystal bar, center due to crystal bar and the center disalignment to mid-game, cause crystal bar to swing when cylindrical grinding, bring the impact of the aspects such as efficiency to cylindrical grinding operation.
(3) summary of the invention
The object of this invention is to provide that a kind of structure is simple, precision is relatively high, can the special positioning fixture that sapphire ingot be connect for group of Quick connecting.
The object of the present invention is achieved like this: it is by handle, screw mandrel, locating centre, support, platform, axial location base and crystal outer circle diameter are to location gusset composition, two pilot holes are provided with above axial location base and platform, crystal outer circle diameter is located by connecting on two pilot holes of axial location submounts to location gusset by two tommys, axial location base to be inserted on platform two corresponding pilot holes by the tommy of two on its bottom surface and to locate and be placed on platform, support adopts screw to be fixed on above platform, screw mandrel is fixed on support, screw mandrel bottom adopts the locating centre that is threaded, screw mandrel top has been screwed a handle, crystal outer circle diameter is 0 ° ~ 130 ° to the angle α on gusset both sides, location, thickness is 10 ~ 20 mm, be highly 150 ~ 300 mm, two length of sides are 50 ~ 300 mm.
The present invention also has some features like this:
The shape of 1, described axial location base is square, leg-of-mutton, and thickness is 15 ~ 25 mm.The size of this positioning seat is cylindrical specification according to the crystal bar of required location and has different specifications.
2, have the pilot hole of placement to mid-game above described axial location base, the diameter in hole is 5 ~ 25 mm, and the degree of depth is 10 ~ 20 mm.
3, described crystal outer circle diameter is to the angle 70 ° ~ 130 ° on gusset both sides, location.
4, described crystal outer circle diameter has different specifications to location gusset and axial location base, is matching used according to the specification of the crystal bar of required location.
The size of positioning body of the present invention is cylindrical specification according to the crystal bar of required location and has different specifications.First the positioning component location for a certain specification outside diameter crystal bar is placed on platform when realizing.Then one accordingly to the termination of mid-game put on axial location base to mid-game pilot hole; By required crystal bar glue to mid-game successively group connect, make when group connects crystal bar external diameter and both sides from crystal outer circle diameter to positioning body angle near; After crystal bar group connects, the upper end glue group of its crystal bar connect a required specification to mid-game; Turning handle again, makes leading screw move down, in the termination allowing locating centre enter mid-game, suitably afterburning, ensure upper and lower two to the right alignment between mid-game and crystal bar, also increase group connect to the firmness between mid-game, crystal bar.
Beneficial effect of the present invention is: utilize crystal outer circle diameter to location gusset and axial location base and platform and screw mandrel, top, ensure that right alignment between the crystal bar that connects of group and group connect after crystal bar and two coaxial accuracies to mid-game, also the certain pressure by applying, ensure that group connects to the firmness between mid-game, crystal bar.In addition, the raising of coaxial accuracy decreases the required reserved removal amount of crystal bar, shortens process period.Meanwhile, the efficiency that group connects obtains and increases substantially, and solves and causes crystal bar to swing when cylindrical grinding, brings the problem of the aspect impacts such as efficiency to cylindrical grinding operation.
(4) accompanying drawing explanation
Fig. 1 is the schematic diagram of structure of the present invention;
Fig. 2 is the positioning component structural representation that crystal outer circle diameter forms to location gusset and axial location base;
Fig. 3 is the vertical view of Fig. 2.
(5) embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated:
Composition graphs 1-Fig. 3, the present embodiment comprises platform 5 and is fixed on the support 4 on platform, and support 4 is provided with screw mandrel 2 above, and the upper end of screw mandrel 2 is fixed with the handle 1 moved up and down for adjusting screw mandrel 2, and its underpart screw thread is fixed wtih centering locating centre 3.
Crystal outer circle diameter is position connection by the tommy of correspondence and pilot hole to positioning body 6 and axial location base 7.The pilot hole 8 of placement to mid-game termination is had above axial location base 7 upper surface.Its diameter 5 ~ 30 mm, the degree of depth is at 10 ~ 30 mm.
Corresponding to the crystal outer circle diameter of different size crystal bar outside diameter to positioning body 6 and axial location base 7, composition is used for the positioning component of different outside diameter crystal bar respectively.
Positioning component is by tommy and pilot hole, and location is placed on platform.The size of positioning body is cylindrical specification according to the crystal bar of required location and has different specifications.
