Abstract
The invention relates to the technical field of clamps, and discloses a screw clamp for casting surface treatment. The screw clamp comprises a machine base, a screw and clamping jaws. The screw is in threaded connection to the machine base. One end of the screw is rotationally connected with a transverse plate. The two ends of the transverse plate are hinged to the two clamping jaws respectively. The middles of the clamping jaws are hinged to the machine base. Tension springs are connected between the clamping jaws and the transverse plate. The machine base is further provided with a clamping table located between the two clamping jaws. By means of the scheme, compared with the prior art, a pull rod is replaced by the screw for driving, the screw has the self-locking function, and therefore it is not needed to arrange an additional locking device; and accordingly the device is simplified, and the layout is reasonable.
Description
Technical field
The present invention relates to clamp art.
Background technology
Surface treatment is the process on the top layer that artificial machinery, the process based prediction model forming one deck and matrix is different on substrate material surface.Surface-treated object meets the corrosion resistance of product, wearability, decoration or other features requirements.For metal casting, the surface treatment method that we relatively commonly use is, mechanical grinding, chemical treatment, Surface heat-treatent, sprayed surface, surface treatment is cleaned surface of the work exactly, clean, deburring, degreasing, descale etc.For the foundry goods after die casting, need to carry out simple surface treatment, to make foundry goods reach certain dimensional standard and requirement, be convenient to deposit and transport, also reach the requirement of sale simultaneously.
Also being varied for the fixture manufactured by cast(ing) surface process, there is a kind of foundry goods fixture at present, by arranging jaw on support, jaw is hinged on support, and the lower end of jaw is hinged on a pull bar, by pulling pull bar, jaw is rotated, thus realizes clamping.But the pull bar in the program is not easily in the use of reality, also need to be equipped with locking device, the conduct of pull bar is large simultaneously simultaneously, causes the space of installing to increase, makes layout reasonable not.
Summary of the invention
The invention is intended to provide a kind of easy to operate, band self-locking cast(ing) surface process screw rod fixture.
Cast(ing) surface process screw rod fixture in this programme, comprise support, jaw, support is also provided with and clamps platform, clamp platform between two jaws, also comprise screw rod, described screw flight is connected on support, one end of screw rod is rotatably connected to transverse slat, respectively with two, the two ends jaw of transverse slat is hinged, is hinged on support, is also connected with extension spring between jaw and transverse slat in the middle part of described jaw.
Beneficial effect: rotary screw, makes screw rod spin feed motion, and because screw rod and transverse slat are for being rotationally connected, therefore promote transverse slat and move, the movement of transverse slat can be done with the jaw at motion plate two ends and rotate, and the pulling force that jaw overcomes extension spring opens, and is convenient to place foundry goods; Being placed on by foundry goods clamps on platform, contra rotating screw, makes screw rod do reverse movement, in like manner, jaw is clamped.Adopt the program, compared with prior art, replace pull bar to drive with screw rod, screw rod itself has auto-lock function, make without the need to being equipped with other locking device, device is simplified, rationally distributed.
Further, described support comprises upper frame and lower support, and upper frame and lower support adopt bolt to be connected, and are convenient to installation and removal, can change the part of base inner and keep in repair at any time.
Further, the one end away from transverse slat on described screw rod is provided with handwheel, is convenient to the rotation of screw rod, more laborsaving.
Further, described in clamp platform and be provided with through hole, poroid foundry goods is convenient to carry out Surface Machining to the endoporus of foundry goods.
Further, described transverse slat is provided with pin, and one end that described extension spring connects transverse slat is connected with this pin, and by the connecting portion of pin as extension spring, process for machining and manufacturing is simple, is also convenient to installation and removal simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of cast(ing) surface process screw rod fixture embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: lower support 1, upper frame 2, clamp platform 21, screw rod 3, handwheel 31, transverse slat 32, pin 321, extension spring 322, jaw 4.
Embodiment is substantially as shown in Figure 1:
Cast(ing) surface process screw rod fixture in this programme, comprise screw rod 3, jaw 4, screw rod 3 is threaded on lower support 1, the upper end of screw rod 3 is rotatably connected to transverse slat 32, respectively with two, the two ends jaw 4 of transverse slat 32 is hinged, is hinged on upper frame 2, is also connected with extension spring 322 between jaw 4 and transverse slat 32 in the middle part of jaw 4, support is also provided with and clamps platform 21, clamp platform 21 between two jaws 4.
The top of screw rod 3 processes two shoulders, and transverse slat 32 is through screw rod 3 and two shoulders, shoulder can carry out spacing to transverse slat 32, can also ensure the rotation of transverse slat 32 simultaneously.Upper frame 2 adopts bolt to be connected with lower support 1, is convenient to installation and removal, can changes the part of base inner and keep in repair at any time.The lower end of screw rod 3 is provided with handwheel 31, is convenient to the rotation of screw rod 3, more laborsaving.
Clamp on platform 21 and drilled through through hole, poroid foundry goods is convenient to carry out Surface Machining to the endoporus of foundry goods.Transverse slat 32 is inserted with pin 321, one end that extension spring 322 connects transverse slat 32 is connected with this pin 321, and by the connecting portion of pin 321 as extension spring 322, process for machining and manufacturing is simple, is also convenient to installation and removal simultaneously.
Operation principle: by handwheel 31 rotary screw 3, screw rod 3 is spinned feed motion, because screw rod 3 and transverse slat 32 are for being rotationally connected, therefore promote transverse slat 32 to move, the movement of transverse slat 32 can be done with the jaw 4 at motion plate 32 two ends and rotate, the pulling force that jaw 4 overcomes extension spring 322 opens, and is convenient to place foundry goods; Foundry goods is placed on and clamps on platform 21, contra rotating screw 3, make screw rod 3 do reverse movement, in like manner, jaw 4 is clamped.Replace pull bar to drive with screw rod 3, screw rod 3 itself has auto-lock function, make without the need to being equipped with other locking device, device is simplified, rationally distributed.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
