Abstract
The utility model discloses a cylindrical grinder clamp for a sleeve type component. The clamp comprises a mandrel, a spring, wedge blocks, a wedge block guide sleeve, a press block and a nut; mandrel center holes are arranged at two end faces of the mandrel; a mandrel step is arranged at one end of the mandrel; the spring is arranged on the mandrel step; the wedge block guide sleeve is sheathed with the mandrel; moreover, the large end is closely adhered on the end face of the mandrel step; guide slots are uniformly distributed on the top circle surface of the wedge block guide sleeve; a set of wedge blocks mutually matched with the wedge block guide sleeve are inserted into the guide slots through a lower conducting bar and positioned on the wedge block guide sleeve; the small ends of the wedge blocks are connected with the spring; the press block is sheathed on the mandrel and compressed at the large ends of the wedge blocks through the nut. The clamp is linked and clamped by the wedge blocks so that the structure is compact and the operation is simple, convenient and reliable; therefore, the labor strength of workers is reduced, the production efficiency is improved, and the practicability is very strong.
Description
Technical field
The utility model relates to a kind of cylindrical grinder anchor clamps, specifically a kind of cover parts fixture for grinding machine that grinding part cylindrical is used on cylindrical grinder.
Background technology
Along with rapid development of economy, the cylindrical fixture for grinding machine generally uses on lathe in industrial circle, but has also occurred many defectives in production application, for example: the datum coincidence when fixture for grinding machine can not ensure the part Cylindrical Grinding Processes, cause mismachining tolerance bigger, influence the quality of product; For the processing of the cover parts of difformity, different radial dimension or different axial dimensions, in order to realize clamping, need change grip device often to workpiece, increased the jig Design manufacturing cost virtually and produced the preparatory period, increase production cost.Adopt existing anchor clamps, the lay day of workpiece is longer, and the uniformity of the endoporus of cover parts and the axial line of axle is relatively poor, can not satisfy the axiality requirement between cover parts cylindrical and the endoporus, thereby can not guarantee the crudy of part.
Summary of the invention
In order to overcome problems of the prior art, the purpose of this utility model provides a kind of cover parts peripheral milling anchor clamps, these anchor clamps adopt voussoir interlock clamping, compact conformation, simple to operation reliable, reduced working strength of workers, improve production efficiency, had very strong practicality.
The objective of the invention is to be achieved through the following technical solutions:
A kind of cover parts cylindrical grinder anchor clamps, it is characterized in that: these anchor clamps comprise axle, spring, voussoir, voussoir fairlead, briquetting and nut, be provided with the axle center hole in the axle both ends of the surface, axle one end is provided with the axle step, the axle step is provided with spring, voussoir fairlead and axle suit, and big end is close on the end face of axle step; The outer round surface of voussoir fairlead is evenly distributed with guide groove; One group is inserted in the guide groove with the sliver of the mutually adaptive voussoir of voussoir fairlead by the bottom and is positioned on the voussoir fairlead, and the voussoir small end is connected with spring; Briquetting is sleeved on the axle and is pressed on the big end of voussoir by nut.Between briquetting and nut, be provided with open washer.
The utility model can be realized the clamping of the cover parts of difformity and size; Workpiece adopts the endoporus location, and the datum coincidence principle in the time of guaranteeing the part Cylindrical Grinding Processes is eliminated not coincidence error of benchmark; Voussoir adopts the design of arc surface, can increase the contact area of voussoir and workpiece, has reduced the error that causes workpiece deformation to produce owing to clamping force and cutting force to greatest extent; For the processing of the cover parts of difformity, different radial dimension or different axial dimensions, only need to change voussoir and can realize clamping, thereby reduce the design of Clamping Apparatus manufacturing cost effectively and produce the preparatory period workpiece; Use open washer, the lay day of workpiece is significantly reduced; Anchor clamps adopt four voussoir interlock designs, make the location of workpiece and clamp and carry out simultaneously, and the uniformity of the endoporus of assurance cover parts and the axial line of axle satisfies the axiality requirement between cover parts cylindrical and the endoporus, guarantees the crudy of part.Anchor clamps adopt voussoir interlock clamping, compact conformation, simple to operation reliable, have reduced working strength of workers, have improved production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of voussoir in the utility model.
The specific embodiment
A kind of cover parts cylindrical grinder anchor clamps described in the utility model, see Fig. 1 and Fig. 2, these anchor clamps comprise axle 2, spring 4, voussoir 6, voussoir fairlead 7, briquetting 8 and nut 10, be provided with axle center hole 1 in axle 2 both ends of the surface, axle 2 one ends are provided with axle step 3, axle step 3 is provided with spring 4, voussoir fairlead 7 and axle 2 suits, and big end is close on the end face of axle step 3; The outer round surface of voussoir fairlead 7 is evenly distributed with guide groove; One group is inserted in the guide groove with the sliver of the adaptive mutually voussoir 6 of voussoir fairlead 7 by the bottom and is positioned on the voussoir fairlead 7, and voussoir 6 small ends are connected with spring 4; Briquetting 8 is sleeved on the axle 2 and is pressed on the big end of voussoir 6 by nut 10.Between briquetting 8 and nut 10, be provided with open washer 9.
The utility model operation principle is the diameter of bore size according to required processing cover parts, at first designs the diameter dimension of the exterior arc surface of voussoir.Process the length dimension of voussoir then according to the axial dimension size design of required processing cover parts.Workpiece 5 is finished the location with endoporus on the external arc surface of four voussoirs 6.Fastening nut 10 is moved to the left open washer 9 and briquetting 8, and the gathering sill along voussoir fairlead 7 is moved to the left with promoting four voussoir 6 constant speed, and four voussoirs 6 are realized the location and the clamping of workpiece 5 along the outside constant speed movement of the radial direction of voussoir fairlead 7 simultaneously.Finish the grinding of cylindrical when cover parts after, unscrew nut 10, rely on the elastic force of four springs 4 to promote voussoir 6 simultaneously and move right, make workpiece released, can realize freely loading and unloading of workpiece along the gathering sill of voussoir fairlead 7.And when bigger change took place for the axial length of workpiece or radial diameter size, a voussoir that only needs to change different size got final product.The open washer of setting up 9 can make the lay day of workpiece significantly reduce.
