Description

Drilling and milling device for machining precision connecting piece

Technical Field

The utility model relates to a processing of precision connection spare is with boring milling device.

Background

The biopsy forceps are indispensable tools for taking pathological specimens in endoscopic examination, and at least comprise forceps clamps, connecting plates and pull rod connectors, wherein the pull rod connectors are connected with the connecting plates, the connecting plates are connected with the forceps clamps, the three form a four-bar mechanism, and the forceps clamps can form unfolding and closing effects when the pull rod connectors are pushed and pulled. The pull rod connector is a small part with the length of 4-5 mm and the width of 3-4 mm, and is a precise connecting piece. The precision connecting piece is of a T-shaped structure integrally and consists of a columnar part and a flat rectangular part, and the flat rectangular part is also provided with a through hole for connecting a connecting plate. The semi-finished product before the precision connecting piece is processed is formed by combining two sections of cylindrical parts, namely one section of the semi-finished product is cylindrical, the other section of the semi-finished product is also cylindrical, and only the radius of the two sections of cylindrical parts is larger and smaller, so that the section of the semi-finished product on the central line is in a convex shape. The semi-finished product to the finished product precision connecting piece needs to adopt a milling process, and the section with larger radius of the semi-finished product is milled in the direction vertical to the central line of the semi-finished product, so a milling device is needed when the precision connecting piece is produced.

The milling tool for the precision connecting piece in the prior art only has the function of milling one surface by one-time operation, and because two surfaces of a semi-finished product need to be milled, the milling operation of the same precision connecting piece in the prior art needs to adopt two positioning operations. During operation, the semi-finished product is fixed on the milling device, the grinding wheel firstly mills a plane on the semi-finished product, then the semi-finished product is loosened and rotates one hundred eighty degrees, then the semi-finished product is fixed on the milling device, and the grinding wheel mills another plane on the semi-finished product. Ideally, the two planes should be parallel.

The milling operation is a manual milling mode, a worker needs to place a precise connecting piece on a station, mill a plane in one direction firstly, then fix the precise connecting piece again and mill a plane in the other direction, and obviously, the defects of manual groove milling operation are low production efficiency and high labor intensity. Meanwhile, in the process, the positioning operation is needed again between the first milling and the second milling, the manual rotating angle is not always the same every time, and the rotating angle cannot be ensured to be consistent with the set angle, so that the flat structure obtained by manual milling is not ideal enough, and the quality of the precision connecting piece is lower than the design requirement.

The pull rod connector also needs to drill a hole at the flat rectangular part to obtain a finished product, so a drilling device is needed during the production of the precise connecting piece. The milling operation and the drilling operation are two independent processes which are respectively and independently carried out on two devices in a manual mode. Therefore, the semi-finished product obtained by the milling operation needs to be subjected to a positioning operation by a worker during the drilling operation, and then a through hole is obtained in the flat rectangular part of the precision connecting piece; if another through hole needs to be drilled, the drilling operation needs to be carried out after one manual positioning operation. The manual drilling operation has low working efficiency and low quality stability, and the main reason is that a new positioning operation is needed before the step of drilling each through hole is implemented, and if the positioning operations are different, the machining precision of the through holes is easily influenced, and the phenomena of position deviation and large aperture occur.

In the process, the materials do not need to be rotated, namely the space postures of the materials are not changed, only the space positions of the materials are changed, and the process is completely different from the processing process in the prior art.

Burr can be formed on the lower surface of the material after drilling, and the material is ground by the grinding wheel when passing through the second milling station again, so that the burr can be removed. I.e. the subsequent separate deburring step is omitted, whereby the component ready for assembly is obtained by milling, drilling and deburring.

The operation of supplying the material to the holder requires that an exact position state be established between the material and the holder, which is done by a positioning operation that is also necessary and unique in the milling operation. The material can realize the location operation through the speed of fold of control anchor clamps after extruding the mode output from the feed pipe, and this needs the device to obtain through debugging repeatedly before the operation, and the process is more loaded down with trivial details.

Since the drilling station is located at one end of the path of the linear reciprocating motion of the drill bit 21, the drill bit 21 can be inserted into the drilling station while the drill bit 21 reciprocates in the vertical direction.

In an initial state, the limiting cylinder 4 contracts; the clamp 2 is positioned in the clamping station and swings to a horizontal state, the clamp 2 is positioned in the groove 7, the opening direction of the clamping plate of the clamp 2 is positioned in the horizontal plane, the front of the opening of the clamping plate of the clamp 2 is just the outlet of the feeding pipe 3, a material in the feeding pipe 3 is already output on the carrying surface 6, and due to the friction force between the output material and the carrying surface 6, the output material blocks other materials in the feeding pipe 3 and cannot move outwards; the first milling insert 10 is disengaged from the first milling station and the second milling insert 11 is disengaged from the second milling station; both the first milling insert 10 and the second milling insert 11 are rotated; the drill bit 21 is disengaged from the drilling station and the drill bit 21 is in rotation.

After two times of milling, the formed plane of the surface of the material is in the horizontal plane. The fixture 2 brings the material into a drilling station and is positioned right below the drill bit 21, the drill bit 21 drills a through hole at the flat rectangular part of the material after descending, and then the drill bit 21 resets to enter a higher position; then, the clamp 2 drives the material to translate again, so that the material is located under the drill bit 21 at other parts of the flat rectangular part, another through hole is drilled at the flat rectangular part of the material after the drill bit 21 descends, and then the drill bit 21 returns to a higher position. Thus, the milling operation and the drilling operation are performed on the material, the holder 2 is returned to the second milling station, the first milling insert 10 is then brought into the first milling station, the second milling insert 11 is brought into the second milling station, the material is again subjected to the machining treatment by the second milling insert 11, the second milling insert 1 is brought into contact with the material at a position below the material, and the other side of one end of the material is milled again.
