Description

The robot Clamping Apparatus of Connecting Rod

Technical field

The utility model relates to field of machining, particularly a kind of robot Clamping Apparatus of Connecting Rod.

Background technology

Connecting rod is the very important parts of robot, and this Workpiece length is longer, reaches 1121mm, and the bearing hole wall is thinner, and the thickest position has only 11mm (monolateral), and in addition, the core width is narrower, and thickness is thinner, and the dimensional accuracy and the form accuracy of dead eye are higher simultaneously.Therefore, in clamping and the process, workpiece very easily is out of shape, and is difficult to reach the required precision of workpiece, and this is the place of the processing difficulties of this workpiece just also.

Summary of the invention

The purpose of this utility model is to design a kind of robot Clamping Apparatus of Connecting Rod, so that the form accuracy of connecting rod and dimensional accuracy can satisfy the needs of produced on-site satisfying under the above-mentioned requirements condition, is applicable to and produces in enormous quantities and produce by batch.

For achieving the above object, the technical solution of the utility model is,

Robot of the present utility model Clamping Apparatus of Connecting Rod, these anchor clamps are divided into two parts, i.e. preceding working procedure anchor clamps and later process anchor clamps two parts, the shared base plate of two parts anchor clamps;

The preceding working procedure anchor clamps comprise, base plate; Two boss are symmetrical arranged a side of base plate upper surface; The upper surface of each boss is provided with two jaw body along the base plate radial symmetric, and jaw body is an arc; Be positioned at the through hole that the jaw body near the outside also offers, jaw body has fixedly slotted eye along the base plate radial symmetric; Claw is arranged at and is positioned near the fixing slotted eye of the jaw body in the outside, and an end convexedly stretches in the jaw body medial surface, and the other end stretches out fixedly slotted eye of jaw body; Spacer is arranged at the fixedly slotted eye of an other side jaw body, and is fixed by screw; Compact heap, L-shaped structure is arranged at the outside near a jaw body in the outside; Screw is established in its upper surface, stretch out jaw body fixedly an end claw of slotted eye be connected and fixed on the compact heap by a lock-screw and screw; Compact heap middle part is provided with the corresponding through hole of offering with a jaw body that is positioned at the close outside of through hole, compresses pin and passes the workpiece of above-mentioned through hole in the claw; The later process anchor clamps comprise, two bases are symmetrical arranged the opposite side of described base plate upper surface, and base central authorities establish fixed groove; Two ringfeder bodies are arranged at respectively on two bases, the ringfeder body in the form of a ring, ringfeder body inner surface is the conical surface; Two mandrels, it comprises the location division on fixed part and the fixed part, and is T-shaped; This fixed part is inserted in base central authorities fixed groove, and the periphery of location division is the inclined-plane that cooperates with the ringfeder body.

Further, described boss is a ring body, and the position screw is set along circumference in the boss upper surface of jaw body inboard.

Advantage of the present utility model is,

The utility model robot Clamping Apparatus of Connecting Rod, simple in structure, number of spare parts is few, is easy to processing and manufacturing, and in addition, the rigging error that these anchor clamps produced is little, has only this front and back two procedures because of whole work-piece again, so there is not the phenomenon of changing anchor clamps again in the process; Because this two procedures processing content is identical, natural cutter is also identical, has so just saved tool change time simultaneously.

The specific embodiment

Referring to Fig. 1～Fig. 5, robot of the present utility model Clamping Apparatus of Connecting Rod, these anchor clamps are divided into two parts, i.e. preceding working procedure anchor clamps and later process anchor clamps two parts, the shared base plate of two parts anchor clamps.

Preceding working procedure anchor clamps I comprises, base plate 1; Two boss 2,2 ' are symmetrical arranged a side of base plate 1 upper surface; The upper surface of each boss 2 (is example with boss 2) is provided with two jaw body 3,3 ' along the base plate radial symmetric, and jaw body 3,3 ' is an arc; Be positioned at the through hole 31 that the jaw body 3 near the outside also offers, jaw body 3,3 ' has fixedly slotted eye 32,31 ' along the base plate radial symmetric; Claw 4, be arranged at be positioned near the jaw body 3 in the outside fixedly slotted eye 32, one ends convexedly stretch in jaw body 3 medial surfaces, the other end stretches out fixedly slotted eye 32 of jaw body 3; Spacer 12 is arranged at the fixedly slotted eye 31 ' of an other side jaw body 3 ', and fixing by screw 14; Compact heap 5, L-shaped structure is arranged at the outside near the jaw body 3 in the outside, screw 51 is established in its upper surface, claw 4 stretch out jaw body 3 fixedly an end of slotted eye 32 be connected and fixed on the compact heap 5 by a lock-screw 6 and screw 51; Compact heap 5 middle parts are provided with the corresponding through hole 52 of the through hole offered with a jaw body 3 that is positioned near the outside 31, compress pin 7 and pass the workpiece 13 of above-mentioned through

hole

52,31 in the claw;

Later process anchor clamps II comprises two bases 8,8 ', is symmetrical arranged the opposite side of described base plate 1 upper surface, and base 8,8 ' (is example with base 8) central authorities establish fixed groove 81; Two ringfeder bodies 9,9 ' are arranged at respectively on two bases 8,8 ', and the ringfeder body is an example with ringfeder body 9 in the form of a ring, and ringfeder body 9 inner surfaces 91 are the conical surface; Two mandrels 10,10 ' are example with mandrel 10, and it comprises the location division 102 on fixed part 101 and the fixed part 101, and is T-shaped; This fixed part 101 is inserted in base 8 central fixed grooves 81, and the periphery 1021 of location division 102 is the inclined-plane that cooperates with ringfeder body 9.
