Abstract
The utility model discloses an engine cylinder block machining clamp which comprises a clamp body. A bottom surface supporting plate, a bottom surface locating pin and a bottom surface pressing mechanism are respectively arranged on the clamp body and corresponding to the position of a fastened portion of the bottom surface of an engine cylinder block to be machined. A top surface supporting plate, a top surface locating pin and a top surface pressing mechanism are arranged on the clamp body and corresponding to the position of a fastened portion of the top surface of the engine cylinder block to be machined. The bottom surface pressing mechanism and the top surface pressing mechanism are detachably connected with the clamp body. The engine cylinder block machining clamp has the advantages of being capable of finishing more machining at one machining center on the basis of meeting requirements of machining accuracy.
Description
Technical field
The utility model relates to anchor clamps manufacturing technology field, relates in particular a kind of engine cylinder-body clamp for machining.
Background technology
Engine cylinder-body is being carried out the machine added-time, need to finish the processing at the positions such as end face, cylinder hole, large light section, left and right sides intake and exhaust face, crankshaft hole, bottom surface, thrust surface, saying that working position is summarized comprised 6 hole faces and inner chamber multiaspect.Existing engine cylinder-body clamp for machining generally is to utilize gripper shoe, alignment pin and the hold-down mechanism clamping product of a cartridge clip on concrete, finishes the processing of 3-5 face, then utilizes another set of anchor clamps to finish the processing that remains the position.Just can finish the processing of product because engine cylinder-body is added man-hour needs two sleeve clamps, need to change anchor clamps in the process, affect working (machining) efficiency, in addition, the increase of anchor clamps quantity, the utilization rate of equipment is lower, causes the waste of resource.
Summary of the invention
The purpose of this utility model provides a kind of engine cylinder-body clamp for machining, and it can satisfy on the basis of requirement on machining accuracy, finishes more multi-processing content at a machining center.
A kind of engine cylinder-body clamp for machining described in the utility model, comprise clamp body, be respectively equipped with engine cylinder-body bottom surface to be processed at clamp body and need clamp the corresponding bottom supporting plate in position, position, bottom surface alignment pin and bottom surface hold-down mechanism, also be provided with engine cylinder-body end face to be processed and need clamp the corresponding end face gripper shoe in position, position, end face alignment pin and end face hold-down mechanism; Described bottom surface hold-down mechanism and end face hold-down mechanism and clamp body are for removably connecting.
Described bottom supporting plate, bottom surface alignment pin, end face gripper shoe and end face alignment pin and clamp body are for being fixedly connected with, to satisfy the requirement of machining accuracy.
Engine cylinder-body clamp for machining described in the utility model is designed into the devices such as the support of original 2 stations, location, clamping on the clamp body, because bottom surface hold-down mechanism and end face hold-down mechanism and clamp body are dismountable, anchor clamps are when work, alignment pin by separately positions, its accurate positioning, clamping are reliable, mutually noninterfere and impact, satisfying on the basis of requirement on machining accuracy, realize finishing at a machining center purpose of more multi-processing content, improved the utilization rate of working (machining) efficiency and equipment.
Description of drawings
Fig. 1 is top view of the present utility model;
Fig. 2 has taken off the A of bottom surface hold-down mechanism to view in 1 among the figure.
The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by coming by reference to the accompanying drawings.
As depicted in figs. 1 and 2, this engine cylinder-body clamp for machining comprises clamp body 7, be respectively equipped with engine cylinder-body bottom surface to be processed at clamp body 7 and need clamp the corresponding bottom supporting plate 2 in position, position, bottom surface alignment pin 1 and bottom surface hold-down mechanism 3, also be provided with engine cylinder-body end face to be processed and need clamp the corresponding end face gripper shoe 5 in position, position, end face alignment pin 4 and end face hold-down mechanism 6; Described bottom surface hold-down mechanism 3 and end face hold-down mechanism 6 and clamp body are for removably connecting.Described bottom supporting plate 2, bottom surface alignment pin 1, end face gripper shoe 5 and end face alignment pin 4 and clamp body 7 are for being fixedly connected with.
Engine cylinder-body clamp for machining described in the utility model mainly applies to 5 axle machining centers, and the geometric accuracy of jig Design manufacturing and 5 axle machining center workbenches are consistent.Before the clamping, edited the clamp body coordinate system, measure bottom surface alignment pin and end face alignment pin origin position, bottom surface alignment pin and end face alignment pin are controlled in the 0.005mm with respect to each gripper shoe face perpendicularity, and bottom supporting plate and end face gripper shoe are controlled in the 0.01mm with respect to the equipment workbench depth of parallelism; During clamping, can distinguish concrete clamping position according to different location structures, carry out respectively 2 procedure positioning and clamping and processing, corresponding processing with corresponding nc program can improve utilization rate of equipment and installations, has again fine practicality and operability; Behind the clamping, two groups of locating clip clamping systems of end face and bottom surface mutually must not interfere, affect, and hold-down mechanism is reliable, safety, and nc program can be carried out smoothly, and the Product Precision of processing can reach parts design figure required precision.
Engine cylinder-body is being added man-hour: the first step, utilize first bottom surface alignment pin, bottom supporting face and bottom surface hold-down mechanism location to clamp, processing top perimeter zone, the end face hold-down mechanism of this moment separates with clamp body; Second step, the bottom surface hold-down mechanism is taken off from clamp body, the end face hold-down mechanism is installed on the clamp body, engine cylinder-body again overturns, utilize end face alignment pin, end face supporting surface and end face hold-down mechanism location to clamp, process bottom periphery and cavity region, thereby realized finishing at the platform machining center processing of engine cylinder-body.
