Description

Tension and compression clamping device outside columnar workpiece
Technical field
The utility model is related to a kind of clamping device, tension and compression clamping device outside particularly a kind of columnar workpiece.
Background technology
For workpiece, when carrying out the processing of some surfaces, it usually needs by piece-holder and fix.Such as workpiece is carried out When sandblasting is processed, need workpiece fixation could carry out it sandblasting operation, but existing clamping device is troublesome in poeration, clamps Effect is bad, and complex structural designs, and number of assembling steps is cumbersome, and manufacture is of high cost.
Utility model content
The purpose of this utility model is that solving above-mentioned technical problem, tension and compression outside a kind of columnar workpiece are provided and clamp dress It puts, there is simple in structure, the good feature of easily operated and clamping effect.
In order to solve the above technical problems, the utility model employs tension and compression clamping device outside a kind of columnar workpiece, including Pedestal, wherein, the pedestal is equipped with the through-hole of " recessed " shape, and clamping jaw is respectively equipped in two vertical sections of the through-hole, described The middle part of clamping jaw is hinged with the pedestal, and the pedestal is stretched out in the upper end of the clamping jaw, and spiral shell is equipped in the horizontal segment of the through-hole Bar is placed in the middle part of the screw rod in U-shaped bearing set on the pedestal and is rotatablely connected with the U-shaped bearing, the spiral shell Two pieces of limiting plates are equipped with close to the position of the U-shaped bearing on bar, the limiting plate is respectively arranged on the both sides of the U-shaped bearing, The both ends of the screw rod are equipped with swivel nut, and the swivel nut coordinates respectively with reverse thread set on the screw rod, on the swivel nut Axis pin is equipped with, the axis pin is set in the U-lag that Open Side Down set by the lower end of the clamping jaw;The pedestal is equipped with Section is the supporting table of V-arrangement, and the supporting surface of the supporting table is opposite with the clamping face of the clamping jaw.
Further, it is set on the screw rod to screw handle in above-mentioned technical proposal.
Further, in above-mentioned technical proposal, the lower end of the U-shaped bearing is equipped with fixed plate, the fixed plate with it is described Pedestal is fixedly connected.
Advantageous effect possessed by the utility model:By the operation to screw rod, due to the reverse thread and spiral shell on screw rod Set cooperation, while rotation, the just opposite or movement of supporting or opposing of energy band movable snail sleeve realizes that swivel nut drives the movement of clamping jaw, so as to have Effect by Workpiece clamping or loosen, the design is simple in structure, simple operation, and screw drive have good self-locking effect, keep away Exempted from it is lasting force and bring it is inconvenient the problem of.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Wherein:Pedestal 1;Through-hole 2;Vertical section 21;Horizontal segment 22;Clamping jaw 3;Screw rod 4;Screw handle 5;U-shaped bearing 6;It is fixed Plate 7;Limiting plate 8;Swivel nut 9;Axis pin 10;U-lag 11;Supporting table 12;Workpiece 13.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1, the utility model provides tension and compression clamping device outside a kind of columnar workpiece, including pedestal 1, wherein, Pedestal 1 is equipped with the through-hole 2 of " recessed " shape, and clamping jaw 3, the middle part of clamping jaw 3 and pedestal are respectively equipped in two vertical sections 21 of through-hole 2 1 is hinged, and pedestal 1 is stretched out in the upper end of clamping jaw 3, is equipped with screw rod 4 in the horizontal segment 22 of through-hole 2, set on screw rod 4 to screw handle 5, screw rod 4 middle part is placed in U-shaped bearing 6 set on pedestal 1 and is rotatablely connected with U-shaped bearing 6, and the lower end of U-shaped bearing 6, which is equipped with, to be fixed Plate 7, fixed plate 7 are fixedly connected with pedestal 1, and two pieces of limiting plates 8 are equipped with close to the position of U-shaped bearing 6 on screw rod 4, and limiting plate 8 divides Not She Yu U-shaped bearing 6 both sides, the both ends of screw rod 4 are equipped with swivel nut 9, and swivel nut 9 is matched respectively with reverse thread set on screw rod 4 It closes, axis pin 10 is equipped on swivel nut 9, axis pin 10 is set in the U-lag 11 that Open Side Down set by the lower end of clamping jaw 3;Pedestal 1 The supporting table 12 that section is V-arrangement is equipped with, the supporting surface of supporting table 12 is opposite with the clamping face of clamping jaw 3.
Workpiece 13 is placed in supporting table 12, screws screw rod 4 later, screw rod 4 drives swivel nut 9 to do mutually from movement, 9 band of swivel nut The lower end of dynamic clamping jaw 3 is done mutually from movement, and upper end moves toward one another, and realizes the clamping to workpiece 13, reversely screws screw rod 4 later, Swivel nut 9 moves toward one another, and swivel nut 9 drives the lower end of clamping jaw 3 to move toward one another, and upper end is done mutually from movement, is realized to workpiece 13 Loosen.
The description and the appended drawings of the utility model are considered illustrative and not restrictive, on the utility model basis On, for those skilled in the art according to disclosed technology contents, not needing to performing creative labour can be to some of technology Feature makes some and replaces and deform, within the protection scope of the present utility model.
