Description
Technical field
The utility model belongs to Machining Technology field, relates to a kind of Simple clamp, is specifically related to a kind of screw drive type milling hold down gag.
Background technology
Milling Process is a kind of common metal cold processing mode, in Flank machining process milling cutter under the driving of main shaft around axle center High Rotation Speed, workpiece to be machined remains static under the clamping of corresponding fixture, and the milling cutter of High Rotation Speed uses side blade by workpiece to be machined machine-shaping., generally there is volume large in conventional Milling Process hold down gag, dismounting inconvenience, and requirement on machining accuracy is high, compresses efficiency low.The shortcomings such as labour intensity is large, and the leading time is long.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, there is provided a kind of screw drive type milling hold down gag, it is reasonable in design, and Workpiece clamping is reliable, structure is simple, easy to operate, dismounting is convenient, is convenient to carrying, long service life, applied widely, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of screw drive type milling hold down gag, comprise the L shape mount pad for carrying rectangular piece, described L shape mount pad is provided with multiple holddown groove for fixing described L shape mount pad, it is characterized in that: also comprise top board and the cooperatively interact thread bush and screw rod that form screw thread pair; One end of described top board is fixedly connected with the sidewall of described L shape mount pad, described thread bush is fixedly mounted in the middle part of described top board, described screw rod is provided with in described thread bush, described screw rod lower end is rotatablely equipped with the presser feet for compressing rectangular piece, and described screw rod upper end is fixedly installed the driving handle for driving described bolt rotary.
Above-mentioned screw drive type milling hold down gag, is characterized in that: described top board is welded on the sidewall of described L shape mount pad.
Above-mentioned screw drive type milling hold down gag, is characterized in that: described screw rod lower end and described presser feet hinged.
The utility model compared with prior art has the following advantages:
(1) design of this screw drive type milling hold down gag is very reasonable, drives screw rod to compress rectangular piece by screw thread pair by driving handle, and thus it compresses very reliable, and reinforcement is large.
(2) this screw drive type milling hold down gag is simple and compact for structure, and operating personnel only need rotary motion handle can clamp or unclamp columnar workpiece, operates very easy.
(3) this screw drive type milling hold down gag compact, lightweight, easy accessibility, is convenient to carrying and safeguards.
(4) in use there is not rigid shock in this screw drive type milling hold down gag, and thus its service life is very long.
(5) this screw drive type milling 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 screw drive type milling 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 utility model is described in further detail.

Description of reference numerals:
1-L shape mount pad; 2-rectangular piece; 3-presser feet;
4-top board; 5-thread bush; 6-screw rod;
7-driving handle.
Detailed description of the invention
A kind of screw drive type milling hold down gag as shown in Figure 1, comprise the L shape mount pad 1 for carrying rectangular piece 2, described L shape mount pad 1 is provided with multiple holddown groove 1-1 for fixing described L shape mount pad 1, also comprises top board 4 and the cooperatively interact thread bush 5 and screw rod 6 that form screw thread pair; One end of described top board 4 is fixedly connected with the sidewall of described L shape mount pad 1, described thread bush 5 is fixedly mounted in the middle part of described top board 4, described screw rod 6 is provided with in described thread bush 5, described screw rod 6 lower end is rotatablely equipped with the presser feet 3 for compressing rectangular piece 2, and described screw rod 6 upper end is fixedly installed the driving handle 7 for driving described screw rod 6 to rotate.
In the present embodiment, described top board 4 is welded on the sidewall of described L shape mount pad 1.
In the present embodiment, described screw rod 6 lower end and described presser feet 3 hinged.
The course of work of the utility model screw drive type milling hold down gag is: as shown in Figure 1, first bolt is used to be fixedly mounted on platen by the holddown groove 1-1 on L shape mount pad 1 by this screw drive type milling hold down gag, rectangular piece 2 is placed on L shape mount pad 1, operating personnel drive screw rod 6 to rotate forward by driving handle 7, and screw rod 6 moves downward thus drives presser feet 3 to compress rectangular piece 2 in thread bush 5.When rectangular piece 2 is processed complete after, rotate backward driving handle 7 and presser feet 3 can be made to unclamp rectangular piece 2.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to the utility model technical spirit any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solutions of the utility model.
