Abstract
The invention discloses a hand-operated self-locking pressing apparatus comprising a base plate having a fixing and supporting action and further comprising a thread sleeve and a screw rod matched with the thread sleeve to form a thread pair, and a housing for an installation of the thread sleeve. The housing is fixed on the upper side of the base plate; the thread sleeve is fixed on the middle of the housing; a screw preventing rotation of the thread sleeve is fixed on the upper side of the base plate; a screw rod is disposed in the thread sleeve; driving handles are fixed on the upper end of the screw rod; and the lower end of the screw rod is hinged with a pressing pin pressing a work piece. The hand-operated self-locking pressing apparatus is characterized by great self-locking property, rational design, simple structure, convenient operation, small size, light weight, convenient assembling and disassembling, easy maintenance, long service life, wide application range, low production cost and easy promotion and use.
Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of Simple clamp, be specifically related to a kind of manual self-locking hold down gag.
Background technology
When carrying out machining to parts, first compression to be positioned to workpiece to be processed, it is multiplex various that workpiece conventional at present steps up mode, hydraulic pressure and the automatic fixture such as pneumatic application are widely, but it is large to there is volume in automatic fixture, dismounting inconvenience, the shortcomings such as requirement on machining accuracy is high, and use cost is high.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, provide a kind of manual self-locking hold down gag, its self-locking performance is good, reasonable in design, structure is simple, easy to operate, compact, lightweight, easy accessibility, is convenient to safeguard, service life is very long, applied widely, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of manual self-locking hold down gag, comprising the base plate play fixed supporting role, it is characterized in that: also comprising the thread bush and screw rod and the housing for installing described thread bush that cooperatively interact and form screw thread pair; Described housing is installed with on the upside of described base plate, described housing central section is installed with described thread bush, the screw for preventing described thread bush from rotating is fixedly installed on the upside of described base plate, described screw rod is provided with in described thread bush, described screw rod upper end is installed with driving handle, and described screw rod lower end is hinged with the presser feet for workpiece pressing.
Above-mentioned manual self-locking hold down gag, is characterized in that: described housing is fixedly mounted on the upside of described base plate by multiple bolt.
Above-mentioned manual self-locking hold down gag, is characterized in that: be interference fit between described thread bush and described housing.
The present invention compared with prior art has the following advantages:
(1) this manual self-locking hold down gag adopts screw rod and thread bush workpiece pressing, and thus its self-locking property is good, highly stable after workpiece is fixed.
(2) this manual self-locking hold down gag design is very reasonable, and simple and compact for structure, operating personnel only need rotating drive handle can compress or unclamp workpiece, operate very easy.
(3) this manual self-locking hold down gag compact, lightweight, easy accessibility, is convenient to safeguard.
(4) in use there is not rigid shock in this manual self-locking hold down gag, and thus its service life is very long.
(5) this manual self-locking hold down gag is not only applicable to Machining Technology field, and be also applicable to the field that other needs to compress, thus its scope of application widely.
(6) requirement on machining accuracy of this manual self-locking hold down gag is low, and a lot of parts are convenient to produce, buy all very much, and thus its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.

Detailed description of the invention
The manual self-locking hold down gag of one as shown in Figure 1, comprises the base plate 1 play fixed supporting role, and also comprises the thread bush 5 and screw rod 7 and the housing 3 for installing described thread bush 5 that cooperatively interact and form screw thread pair; Described housing 3 is installed with on the upside of described base plate 1, described thread bush 5 is installed with in the middle part of described housing 3, the screw 8 for preventing described thread bush 5 from rotating is fixedly installed on the upside of described base plate 1, described screw rod 7 is provided with in described thread bush 5, described screw rod 7 upper end is installed with driving handle 6, and described screw rod 7 lower end is hinged with the presser feet 4 for workpiece pressing 9.
Housing 3 described in the present embodiment is fixedly mounted on the upside of described base plate 1 by multiple bolt 2.
In the present embodiment, be interference fit between described thread bush 5 and described housing 3.
The course of work of the present invention's manual self-locking hold down gag is: first this manual self-locking hold down gag is fixed on operating position, workpiece 9 is held in place on the upside of the base plate 1 in housing 3, rotate forward driving handle 6, driving handle 6 drives screw rod 7 to move downward in thread bush 5, thus makes presser feet 4 workpiece pressing 9 being positioned at screw rod 7 lower end.Otherwise, rotate backward driving handle 6 and can unclamp workpiece 9.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solution of the present invention.
