Detailed description of the invention
Below in conjunction with the accompanying drawings, the utility model is further described.
As depicted in figs. 1 and 2, the machine vise of a kind of adjustable clamp clamp force, including regular jaw caliper (1), activity
Jaw caliper (2) and clamping device (3), described clamping device (3) include jacking block parts (4), screwed pipe (11),
Screw rod (12) and fixing nut (10), described screw rod (12) is located in screwed pipe (11) and moves back and forth along it, screwed pipe
(11) being connected on regular jaw caliper (1) by fixing nut (10), screw rod (12) right-hand member connects jacking block parts
(4), these jacking block parts (4) include fixing jacking block set (5), concave crown block (6), convex jacking block (7) and movable jacking block
Set (8), described screw rod (12) is connected through movable jacking block set (8) with convex jacking block (7).
Described convex jacking block (7) and concave crown block (6) layout the most symmetrical above and below, movable jacking block set (8) is provided with groove one (13),
Convex jacking block (7) is provided with protruding one (14) and projection two (15), and concave crown block (6) is provided with groove two (16) and convex
Playing three (17), fixing jacking block set (5) is provided with groove three (18), and groove one (13) coordinates with protruding one (14)
Connecting, protruding two (15) are connected with groove two (16), and projection three (17) and groove three (18) are connected.
Described fixing jacking block set (5) is connected with moving jaw caliper (2) by screw (19)；Movable jacking block set (8)
It is provided with pin (9), coordinates with the rectangular channel (21) on screwed pipe (11) right-hand member.
The left end of described screw rod (12) is provided with the clamping force graduation mark of demarcation.
Described moving jaw caliper (2) is provided with power transmission pin (20), and this power transmission pin (20) is positioned at described fixing spiral shell
Between female (10) and jacking block parts (4).
