Abstract
The utility model discloses a hydraulic type pressing clamp. The hydraulic type pressing clamp comprises a locating device and a locking device, wherein a locking purpose can be achieved by the locking device through the matching of a nut and a screw rod; the locating device comprises a base which is arranged on a working platform through a bolt, the middle part of the base is provided with a locating hole which is matched with the locating device, and the locating device is arranged in the locating hole on the base; the locking device which is connected with a hydraulic device is arranged above the locating device. The hydraulic type pressing clamp disclosed by the utility model has the advantages that the structure is ingenious, a gear can be effectively locked in a short time through the connection of the head part of the locking device and the hydraulic device, the locking time is saved, and the working efficiency is increased; the bottom part of the locating device is provided with a cylindrical locating platform of which two sides are respectively subjected to one-edge milling, the locating platform has a rotating-prevention function during a locating process, and the locating is reliable; the locking device is in clearance fit with a guide post through an inner groove, a pressing disk and gear teeth are prevented from being difficulty separated due to a suction force formed on end surfaces of the pressing disk and the gear teeth after the gear tooth processing is completed, and the disassembling time of the hydraulic type pressing clamp is saved.
Description
Technical field
The utility model relates to a kind of fluid pressure type compressing fixture, belongs to technical field of tooling clamps.
Background technology
When gear positioning clamp is mainly used in machining gears, make gear keep determine position, be convenient to the later stage gear tooth is processed, mainly by positioner, clamping device, clamp body, Connection Element, formed.During gear tooth shaping, cutting force is larger, is again interrupted cut, vibrates greatlyr, so the clamping force of fixture requires greatlyr, and fixture rigidity, requirement of strength are all higher, and clamp structure design quality directly affects machining accuracy and the working (machining) efficiency of gear tooth.Fixture of the prior art is generally that gear is arranged on the base of being located on workbench, on it, by clamping disk(-sc), nut, screw rod, coordinates, and realizes and clamps object, and whole process completes by workman's manual operations, consuming time too much, is unfavorable for increasing work efficiency; After gear tooth completion of processing, clamping disk(-sc) can produce suction easily inhales gear with compression plate together with under nut extruding, needs be separated by hand, takes time and effort.
Utility model content
For the problems referred to above, the utility model provides a kind of fluid pressure type compressing fixture, and its object is: reliable clamping, shorten fixture and located clamping time, avoid at compression plate and gear teeth end face, forming suction after gear teeth completion of processing, make it be difficult to separately, save the Fixture assembly time.
Technical solution of the present utility model:
A kind of fluid pressure type compressing fixture, comprise positioner, by nut, coordinate the locking device that reaches locking object with screw rod, it is characterized in that: described positioner comprises by bolt and is installed on the base on workbench, in the middle of described base, be provided with the locating hole coordinating with positioner, described positioner is installed in the locating hole on base, is provided with the locking device being connected with hydraulic means above positioner.
Described positioner top is bore positioning cylinder, and middle part is gear face positioning disc, and bottom is that cylindrical shape both sides respectively mill positioning table on one side.
In the middle of on described positioning cylindrical surface, be provided with guide pillar.
Described guide pillar is provided with chamfering.
Described positioner is installed in the locating hole on base by bottom positioning table.
Described locking device upper end is the cylindric clamping head of connecting fluid pressure device, and centre is clamping disk(-sc), and inside is provided with guide pillar by the shrinkage pool of matched in clearance.
The beneficial effects of the utility model:
The utility model structure is ingenious, by locking device head, is connected with hydraulic means, can effectively lock gear at short notice, has saved the locking time, has improved operating efficiency; Positioner bottom is that cylindrical shape both sides respectively mill positioning table on one side, plays anti-rotation effect in position fixing process, and location is reliable; Locking device passes through matched in clearance by interior grooves and guide pillar, avoids at compression plate and gear teeth end face, forming suction after gear teeth completion of processing, makes it be difficult to separately, save fixture disassembly and assembly time.
Accompanying drawing explanation
Fig. 1: the utility model improves pre-structure principle schematic.
Fig. 2: the utility model structural principle schematic diagram.
Fig. 3: the utility model mounting structure principle schematic.
Wherein: 1 positioning cylinder 2 positioning disc 3 positioning table 4 guide pillar 5 clamping disk(-sc) 6 clamping head 7 gear 8 nuts.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
A kind of fluid pressure type compressing fixture as shown in Figures 1 to 3, comprise positioner, by nut 8, coordinate the locking device that reaches locking object with screw rod, described positioner comprises by bolt and is installed on the base on workbench, in the middle of described base, be provided with the locating hole coordinating with positioner, described positioner is installed in the locating hole on base, above positioner, be provided with the locking device being connected with hydraulic means, described positioner top is bore positioning cylinder 1, middle part is gear face positioning disc 2, bottom is that cylindrical shape both sides respectively mill positioning table 3 on one side, 1 upper middle guide pillar 4 that is provided with of described positioning cylinder, described guide pillar is provided with chamfering, described positioner is installed in the locating hole on base by bottom positioning table, described locking device upper end is the cylindric clamping head 6 of connecting fluid pressure device, centre is clamping disk(-sc) 5, inside is provided with guide pillar 4 by the shrinkage pool of matched in clearance.
Specific embodiment:
First by positioner, the positioning table 3 by bottom is loaded in the locating hole of workbench upper bed-plate, then by gear 7, the bore positioning cylinder 1 by positioner top is installed on the positioning disc 2 at positioner middle part, start hydraulic clamp and drive the clamping head 4 on locking device, by inner shrinkage pool, coordinate clamping disk(-sc) 5 is pressed in to gear 7 upper surfaces with positioner top guide pillar 4, realize location and clamp overall process, after completion of processing, close hydraulic means, locking device can be pulled down, because locking device passes through matched in clearance by interior grooves and guide pillar 4, avoid at compression plate and gear teeth end face, forming suction after gear teeth completion of processing, it is difficult to separately, saved fixture disassembly and assembly time.
To sum up, the utility model accomplishes the end in view.
