Abstract

An end positioning and bonding device for a crystal bar consists of a positioning frame and a crystal bar fixing clamp arranged on the positioning frame, wherein the positioning frame is L-shaped; the lower bottom surface of the positioning frame is parallel to the horizontal plane; the side face of the positioning frame is vertical to the lower bottom surface; the lower bottom surface of the positioning frame is fixedly arranged on a crystal bar detector; a fixing screw is arranged at the side face of the positioning frame; the other end of the fixing screw is fixed on the bottom surface of a processing base; the crystal bar is fixedly arranged in a V-shaped groove of the crystal bar fixing clamp; a positioning plate is arranged at the lower end of the V-shaped groove; the positioning plate is fixed on the bottom surface of the positioning plate; a support plate is arranged at the rear end of the positioning frame; and a puller screw is arranged on the support plate. With the adoption of the device, the crystal bar detector is rotated so as to directly find out the minimum position of a deviation angle, and then the angle of the positioning plate is rotated so as to completely eliminate the deviation angle. With the adoption of the technical scheme, the production processes can be effectively reduced, the working efficiency can be improved, the probability of deviations can be decreased, and the rate of finished products can be increased.

Description

Crystal bar termination positioning bonding device

Technical field

The utility model belongs to the crystal processing device technical field, relates to a kind of crystal bar termination positioning bonding device.

Background technology

Crystal such as sapphire at first will cut the two ends of crystal bar with the crystal bar crystalline forming in the growth pot in process of manufacture then, and rounding is carried out in the side of crystal, make crystal bar become a regular cylinder.Before rounding is carried out in the side of crystal, need the end face of crystal bar one end be bonded to and process on the seat, the processing seat is used to be installed to a special-purpose grinding machine fixture, and when the grinding machine fixture rotated at the drive crystal bar, the sharpening of grinding machine was with the side rounding of crystal.Add man-hour carrying out rounding, require cylindrically axially to be a fixing angle with the crystal orientation of crystal, cylindrical axial vertical with the end face at two ends.

Because in the process of crystal production, small deviation can appear in the fixed angle between the crystal orientation of each crystal and the central shaft of cylindrical crystal, promptly forms an angle of deviation; Therefore when the side of processing polishing cylindrical crystal; Need be to axially the revising of crystal, eliminating the angle of deviation, concrete way bonds to processing seat last time with crystal exactly; Gap between adjustment crystal bar and the processing seat contact-making surface; Make processing seat go up crystal bar axially with crystal axially be returned to required fixed angle, so just can eliminate the angle of deviation, the qualification rate of raising product.

In prior art, crystal bar was divided into for two steps with the contact-making surface work of being adhesively fixed of processing seat, the one, earlier on angle of deviation detecting instrument, with the crystal bar positioning and fixing on a locating clip, make crystal bar axially with locating clip on after the end face at two ends vertical; The 2nd, on locating rack; Locating clip vertically is installed on the locating rack upper side; On the bottom surface of locating rack, place the processing seat, processing seat upper surface is parallel with horizontal plane, the lower surface of crystal bar is dropped on the upper surface of processing seat; At contact end face on the gluing of processing seat, crystal bar is cemented on the processing seat with glue with crystal bar.Though this processing method can accurately locate crystal bar and base axially, its operational sequence is more, inefficiency not only, the probability that error occurs is bigger.

Summary of the invention

The utility model is in the prior art, and the contact-making surface of crystal bar and the processing seat problem that the work operation is many, how error appears in use equipment easily that is adhesively fixed provides a kind of crystal bar termination positioning bonding device, and this device technique scheme is following:

Crystal bar termination positioning bonding device is made up of locating rack and the crystal bar geometrical clamp that is installed on the locating rack, and locating rack is L-shaped; Bottom surface is parallel to horizontal plane, and lateral vertical has fixing hole in bottom surface on the bottom surface of locating rack; Fixing hole is installed on the crystal bar detector, on the side of locating rack, has holddown groove, and hold-down screw is housed in the holddown groove; The other end of hold-down screw is fixed on the bottom surface of processing seat, gluing and be bonded in an end of crystal bar on the upper surface of processing seat, and the crystal bar geometrical clamp is made up of " V " shape groove and the geometrical clamp on " V " shape groove; Lower end at " V " shape groove is equipped with a location-plate, at the front end of location-plate and " V " shape groove shaft screw is installed, and the rear end has rotation slot; Lock-screw is installed in the rotation slot; Rear end at locating rack is equipped with fagging, is equipped with on the fagging to hold out against screw, and an end that holds out against screw withstands on the location-plate rear end.

Adopt said apparatus that the crystal bar of crystal and processing seat are carried out when bonding, the processing seat is fixed on the side of locating rack, and locating rack is installed on the crystal bar detector; Rotate detector and find out angle of deviation minimum position, the angle of locating slot on the rotational positioning plate is eliminated the angle of deviation fully again; Lock each hold-down screw this moment, gluing on processing seat upper surface is with holding out against screw with the location-plate sinciput; Crystal bar is closely contacted with the coated face of processing seat, treat that viscose glue solidifies the bonding work in back and promptly accomplishes.

After adopting the present technique scheme, production process reduces, and operating efficiency improves, and the probability that error occurs reduces, and yield rate improves.
