Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a feeding device for a double-headed bearing ultra-precision machine. Background Technology

[0002] The double-head bearing ultra-precision machine uses two ultra-precision heads, which can perform ultra-precision machining simultaneously, or roughing and finishing in two separate processes. During roughing and finishing, the bearing material needs to be transferred by a feeding device. Currently, the existing feeding device pushes the bearing material to the finishing head by introducing compressed gas. During the feeding process, when the air pressure is too high, the bearing material is prone to collision with the previous bearing material, resulting in bumps and quality problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a double-head bearing ultra-precision machine feeding device to address the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A feeding device for a double-headed bearing ultraprecision machine includes a support base, a support column connected to the support base, a feeding seat connected to the support column, a feeding groove inside the feeding seat, a feeding plate at the bottom of the feeding seat extending into the feeding groove, an air passage machined in the feeding plate for introducing compressed gas into the feeding groove, baffles symmetrically arranged at the end of the feeding groove, the baffles being connected to the feeding seat via shafts, one end of the shaft passing through the feeding seat and connected to a gear, a support plate on the back of the feeding seat, a cylinder mounted on the support plate, a rack connected to the movable end of the cylinder via a connecting plate, the rack being positioned between the gears, and teeth machined on both sides of the rack to mesh with the gears.

[0006] Furthermore, a guide seat is connected to the side of the feeding seat, and a guide groove is opened in the guide seat, which leads to the feeding trough.

[0007] Furthermore, a cylinder support plate is installed on the bottom side of the feeding seat, and a pushing cylinder is installed on the cylinder support plate. The movable end of the pushing cylinder is connected to the feeding plate.

[0008] Furthermore, a "V"-shaped positioning opening is provided at the end of the feeding plate.

[0009] Furthermore, the feeding trough has inner grooves on both sides at its end, and baffles are disposed in the inner grooves.

[0010] Furthermore, a connecting seat is provided in the middle of the baffle, and the shaft extends into the connecting seat and is locked to the connecting seat by screws and washers.

[0011] Furthermore, a rubber pad is attached to the surface of the baffle.

[0012] Compared with the prior art, the present invention provides a double-headed bearing ultra-precision machine feeding device, which adds a material blocking device at the discharge port of the feeding device. During the transfer of bearing materials, the material blocking device blocks the next bearing material, reducing collisions between bearing materials and improving product quality.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0020] like Figures 1-5 As shown, a feeding device for a double-headed bearing ultra-precision machine includes a support base 1, a support column 2 connected to the support base 1, a feeding seat 3 connected to the support column 2, a feeding groove 4 formed inside the feeding seat 3, a guide seat 5 connected to the side of the feeding seat 3, a guide groove 6 formed inside the guide seat 5, the guide groove 6 leading to the feeding groove 4, and a feeding plate 7 provided at the bottom of the feeding seat 3, extending into the feeding groove 4. A cylinder support plate is installed on the bottom side of the feeding seat 3. A pusher cylinder 8 is mounted on the cylinder support plate. The movable end of the pusher cylinder 8 is connected to the feed plate 7. The feed plate 7 has a "V" shaped positioning port 9 at its end. The "V" shaped positioning port 9 catches the bearing material rolling down from the guide groove 6. An air passage 10 is machined in the feed plate 7. The air passage 10 faces the "V" shaped positioning port 9. Compressed gas is introduced into the feed groove 4 through the air passage 10 to push the bearing material at the "V" shaped positioning port 9 into the headstock of the next ultra-precision head.

[0021] The feeding trough 4 is symmetrically provided with baffles 11 at its end. The baffles 11 are connected to the feeding seat 3 by a shaft 12. In this embodiment, a connecting seat is provided in the middle of the baffles 11. The shaft 12 extends into the connecting seat and is locked to the connecting seat by screws and washers. One end of the shaft 12 passes through the feeding seat. The shaft 12 and the feeding seat 3 are connected by a bearing. The protruding end of the shaft 12 is connected to a gear 13 by a key block. A support plate is provided on the back of the feeding seat 3. A cylinder 14 is installed on the support plate. The movable end of the cylinder 14 is connected to a rack 15 by a connecting plate. The rack 15 is located between the gears 13. The rack 15 has teeth on both sides and meshes with the corresponding gears 13 through the double-sided teeth.

[0022] During the feeding process, the cylinder 14 controls the rack 15, which pushes the gear 13 to bring the baffles 11 together below to form a clamping opening and block the bearing material. The surface of the baffles 11 is covered with rubber pads 16, which serve as a buffer.

[0023] The feeding trough 4 has inner grooves 17 on both sides at its end. When the baffle 17 is in a vertical state, the baffle 17 is located in the inner groove 17 to prevent the baffle 17 from jamming the bearing material.

[0024] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
