Abstract
The invention relates to a special clamp for inside pulling and locking, which comprises a framework rack and hydraulic cylinders. Two tensioning hydraulic cylinders are horizontally and symmetrically arranged on a side plate of the framework rack, plunger rods of the two tensioning hydraulic cylinders are provided with a positioning shaft arranged on the side plate of the framework rack respectively, a vertical downward pressure plate conveying hydraulic cylinder is arranged at the upper end of the framework rack, and a pressure plate is arranged on the plunger rod of the pressure plate conveying hydraulic cylinder. The clamp special for inside pulling and locking of the roughly milled cylinder head end face of a Danfoss cylinder is reasonable in design, convenient to use, simple to operate and strong in practicability; and the clamp can improve the production efficiency, shorten the production time, reduce the labor intensity of workers and realize large-scale automatic production.
Description
Technical field
The invention belongs to the anchor clamps field, especially a kind of Danfoss cylinder body is rough milled the tight special fixture of zip in the cylinder head end face.
Background technology
In order to prevent that workpiece is offset in process, guarantee the accuracy of processing, workpiece is processed gone to toward needing elder generation that workpiece is positioned and compresses.Because the Danfoss cylinder body belongs to the workpiece of comparison abnormal shape, so its location and compress more complicated.All adopt manual mode when at present it being positioned and compressing, promptly the workman at first installs pressing plate, and then uses housing pin to compress.This manual processing mode has the following disadvantages: 1. the time that compresses and locate is long, and efficient is low, is unfavorable for large-scale production; 2. labor strength height, physical demands is big, and is tired easily; 3. workpiece is when clamping repeatedly, and screw and nut damage easily.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of Danfoss cylinder body reasonable in design, that can enhance productivity, shorten the production time, reduce labor strength to rough mill the tight special fixture of zip in the cylinder head end face.
The present invention solves its technical problem and is achieved through the following technical solutions:
The tight special fixture of zip in a kind of, it is characterized in that: comprise frame-type frame and hydraulic cylinder, horizontal symmetrical is equipped with two tension hydraulic cylinders on the side plate of frame-type frame, all be coated with a locating shaft that is installed on the frame-type framework lateral plate on the plunger rod of these two tension hydraulic cylinders, the upper end of frame-type frame install one straight down send the pressing plate hydraulic cylinder, this send on the plunger rod of pressing plate hydraulic cylinder a pressing plate is installed.
The outermost end of the plunger rod of described two tension hydraulic cylinders all is equipped with stop nut.
All uniform on the frame-type framework lateral plate in described each locating shaft outside four positioning seats are installed.
All clamp a skid plate on described each locating shaft, the middle part of this skid plate is installed in by screw on the side plate of frame-type frame, is set with spring on the screw between side plate and the skid plate.
One handle is all made in the top of described each skid plate, and this handle horizontal cross extends out to the outside of the gripper shoe of frame-type frame upper end.
Two draw-in grooves that can be installed on the tension cylinder plunger bar are made in the below of described pressing plate.
Symmetry is installed two guide pillars on the described gripper shoe of sending pressing plate hydraulic cylinder both sides, and the two ends of pressing plate are set on separately the guide pillar and can slide along the guide pillar guiding.
Advantage of the present invention and beneficial effect are:
1, this special fixture adopts two tension hydraulic cylinders is installed in the horizontal direction, all is coated with a locating shaft that is installed on the frame-type framework lateral plate on the plunger rod of these two tension hydraulic cylinders; Vertical direction install one straight down send the pressing plate hydraulic cylinder, an adjustable pressing plate is installed on the plunger rod of this hydraulic cylinder.This structure drives pressing plate by single hydraulic cylinder, the zip consolidation has showed the Danfoss cylinder body and rough mills the location of cylinder head end face and compress in the double hydraulic cylinder, substituted traditional artificial mounting means, thereby greatly shortened the time of clamping, make operating efficiency improve nearly three times, the automatization level of production is greatly improved, is suitable for the needs of large-scale industrial production.
2, this special fixture adopts advanced anchor clamps to clamp, and when shortening working time, has reduced working strength of workers, has reduced workman's physical demands.
3, the present invention is that a kind of reasonable in design, easy to use, simple to operate, practical Danfoss cylinder body that is exclusively used in is rough milled the tight anchor clamps of zip in the cylinder head end face, uses these anchor clamps to enhance productivity, shortens the production time, reduces labor strength, realizes the scale automated production.

The specific embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
The tight special fixture of zip in a kind of, its innovative point is: comprise frame-type frame 9 and hydraulic cylinder, employed hydraulic cylinder is oil cylinder in the present embodiment.Horizontal symmetrical is equipped with two tension hydraulic cylinders 10 on the side plate 11 of frame-type frame, these two hydraulic cylinders are installed in the outside of side plate, its plunger rod 16 penetrates the side plate of frame-type frame, and all is coated with locating shaft 12 on each plunger rod, and this locating shaft is installed on the side plate of frame-type frame.For the fastness that guarantees to locate, all uniform on the frame-type framework lateral plate in each locating shaft outside four positioning seats 13 are installed.The outermost end of the plunger rod of two tension hydraulic cylinders all is equipped with stop nut 15.
Install on the gripper shoe 3 of the upper end of frame-type frame one straight down send pressing plate hydraulic cylinder 1, an adjustable pressing plate 6 is installed on the plunger rod 4 of this hydraulic cylinder.But this pressing plate roof pressure is on the plunger rod of tension hydraulic cylinder, and two draw-in grooves 7 that can be installed on the tension cylinder plunger bar are made in the below of pressing plate.For the stability that guarantees that pressing plate guiding is slided, symmetry has been installed two guide pillars 2 on the gripper shoe of sending pressing plate hydraulic cylinder both sides, and the two ends of pressing plate are set on separately the guide pillar and can slide along the guide pillar guiding.
For the ease of workpiece 14 is taken off from locating shaft, on each locating shaft, all clamp a skid plate 8, the middle part of this skid plate is installed in by screw 17 on the side plate of frame-type frame, is set with spring 18 on the screw between side plate and the skid plate.The top of each skid plate all is shaped on one handle 5, and this handle horizontal cross extends out to the outside of the gripper shoe of frame-type frame upper end.
