Description
[technical field]
The utility model belongs to sheet tooth class part field, is specifically related to a kind of hydraulic pressure gear grinding clamp.
[background technology]
The required precision that roll flute class part is general very high (reaching GB6 level or higher), the error that the thermal deformation of removing part self produces, fixture is one of chief reason affecting grinding accuracy.Technology many employings static pressure type gear grinding clamp advanced in the world at present, such clamp technology threshold is higher, although the higher ringfeder of clamp precision can rise, scope is very little, for the insufficient clamping force of heavy parts, versatility between fixture is poor, cannot implement quick switching, and expensive.Domestic manufacturer adopts the mode of mechanical type manual clamping, clamping is generally all realize by tighting a bolt, this clamp precision generally all can not be guaranteed, and clamping force is also different according to the custom of operator, the most important thing is that it can not adapt to the demand of automation.Our factory roll flute class part kind is more, the negligible amounts of single kind, needs frequently to change product between each product, and therefore when jig Design, fixture versatility is also the key factor needing to consider.
[utility model content]
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of hydraulic pressure gear grinding clamp, can cater to precision of grinding teeth high, wide in variety, change and produce feature frequently.
In order to achieve the above object, the utility model comprises the body with interstitial hole, pull bar is provided with in the interstitial hole of body, interstitial hole is all stretched out in pull bar two ends, top is provided with upper press cover with pull bar, the top of body is frustum structure, supporting seat is fixed with bottom frustum, supporting seat is provided with ringfeder, body bottom portion is provided with sliding plunger, pull bar is connected with sliding plunger, ringfeder is fixedly connected with pull bar, ringfeder outer setting has ringfeder standard component, the upper oil cavitie of movable piston and the sealing of body composition, body bottom portion is also provided with base, base is provided with the some springs contacted with sliding plunger, body and base form airtight cavity of resorption, sliding plunger can slide up and down in cavity of resorption.
Described body offers the hydraulic fluid port be communicated with upper oil cavitie.
Rubber ring is provided with bottom described upper press cover.
Cavity of resorption between described sliding plunger and body has the pore be in communication with the outside.
Described body and supporting seat and body and base are all bolted.
Described body is provided with the set bolt of locked pull bar.
Described spring is six.
Compared with prior art, hydraulic pressure gear grinding clamp of the present utility model can in upper oil cavitie in oil-filled, sliding plunger is moved downward under the promotion of hydraulic oil, thus reach the object of ringfeder spreading clamping work pieces, unclamping workpiece is that the elastic force provided by some springs of piston lower surface is promoted sliding plunger and moves upward and realize, this fixture has automation loading and unloading function, fixture not only needs to possess automatic clamping function, and automatic release function must be possessed, easy to use, improve operating efficiency.
Further, the utility model is provided with rubber ring, and when upper press cover is by rubber ring workpiece pressing, rubber ring will have a small elastic deformation according to the out-of-flatness situation of workpiece end face, so both play the auxiliary effect compressed, play again the effect of less vibration.
Further, the utility model is provided with pore, and inner chamber and external atmosphere pressure are consistent, and ensure that piston can return rapidly.
[accompanying drawing explanation]
Fig. 1 is the structural representation of a kind of hydraulic pressure gear grinding clamp of the utility model.
[detailed description of the invention]
Below in conjunction with drawings and Examples, the utility model is described further.
See Fig. 1, the utility model comprises the body 6 with interstitial hole, pull bar 12 is provided with in the interstitial hole of body 6, interstitial hole is all stretched out in pull bar 12 two ends, top is provided with upper press cover 1 with pull bar 12, the top of body 6 is frustum structure, supporting seat 5 is fixed with bottom frustum, supporting seat 5 is provided with ringfeder 3, sliding plunger 7 is provided with bottom body 6, pull bar 12 is connected with sliding plunger 7, ringfeder 3 is fixedly connected with pull bar 12, ringfeder 3 outer setting has ringfeder standard component 4, sliding plunger 7 and body 6 form the upper oil cavitie of sealing, base 10 is also provided with bottom body 6, base 10 is provided with the some springs 8 contacted with sliding plunger 7, body 6 and base 10 form airtight cavity of resorption, sliding plunger 7 can slide up and down in cavity of resorption.Body 6 offers the hydraulic fluid port 13 be communicated with upper oil cavitie, rubber ring 2 is provided with bottom upper press cover 1, cavity of resorption between sliding plunger 7 and body 6 has the pore 9 be in communication with the outside, body 6 is all bolted with base 10 with supporting seat 5 and body 6, body 6 is provided with the set bolt 11 of locked pull bar 12.
Preferably, spring 8 is six.
Method of work of the present utility model, comprises the following steps:
Step one, according to accessory size, selects suitable body 1, ringfeder 3, pull bar 12, supporting seat 5 and upper press cover 1;
