Description
Technical field
The utility model relates to the clamp for machining of cam, in particular on milling machine, and the clamping device of the rod member that camshaft is fixed.
Background technology
Fixture and grip device are widely known by the people, and are widely used for manufacturing.Particularly, fixture has various reference surface and point, and parts or instrument can accurately be located.In many process, general application fixture, so that these camshafts can keep correct position relationship in such as punching press, riveted joint, welding, the process of pasting or solidifying.Fixture is considered to requisite parts in processing industry, and is the vitals of calculating processing cost, is also the vitals requiring that logistics is considered in process of production.Most position fixing process all utilizes special fixture to realize.
To in keyway processing on camshaft, because milling machine is when processing, general cutting data is comparatively large, and is multitool tooth interrupted cut, and cutting force more greatly and also changing at any time, make to add and easily produce vibration man-hour, this clamping force for fixture itself requires higher, because camshaft itself belongs to irregular camshaft, now in order to increase the clamping force of fixture to camshaft, need to arrange multiple clamping point, cause the trouble changing camshaft.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of and realize fast clamp to camshaft, meet the enough of clamping force simultaneously.
In order to solve the above problems, the utility model provides Camshaft Key Seat processing milling machine fixture, comprise base, two primary clamp body clamp body being arranged on base both sides and the supporting seat be arranged in the middle part of base, described primary clamp body clamp body comprises matrix, V-block, voussoir, pressing plate and cursor, described matrix is U-shaped shelf structure, vertical bar hole is provided with below described voussoir, pin rod on bar hole and matrix is slidably matched, described V-block is bolted on body upper surface, two block pressur plates are hinged on matrix with voussoir symmetry, described voussoir lower end is the inclined-plane of expansion downwards, described pressing plate lower end is offseted by bolt and inclined-plane, two block pressur plates form the chuck for clamping camshaft relatively, be hinged on U-shaped frame by ratchet mechanism in the middle part of described cursor, one end is hinged on voussoir upper end, cursor the other end arranges handle and unclamps the depression bar of ratchet mechanism, described supporting seat comprises telescopic stand and is fixed on the support on telescopic stand.
The course of work of the present utility model is:
Clamping process: camshaft is placed in primary clamp body clamp body with on supporting seat, by pulling cursor downwards, cursor drives voussoir to move up, the below of voussoir is gradually to both sides expansion, and pressing plate is rotated around pin joint, and the upper end of two pressing plates is gradually near camshaft, by pressing plate, camshaft is clamped, camshaft, by platen clamp, only leaves processing end face, processes for milling cutter.And under the effect of ratchet mechanism, cursor one-directional rotation also keeps the state of cursor, makes pressing plate continue to compress camshaft.
Release process: owing to will realize unclamping fast, only need to be unclamped by the ratchet of depression bar by ratchet, cursor lifts and voussoir is declined, and voussoir declines and pressing plate is flicked to both sides, thus unclamps camshaft.
Due to two main clamps used on base, the mode of operation of two main clamps is identical.
Use technical solutions of the utility model to have following benefit: to control voussoir by handle and make clamp loose and close up, and prevent loosening of fixture by ratchet mechanism, achieve the effect of clamping; Simultaneously fixture only carries out the operation unclamping and clamp by handle, reaches effect fast.
Preferably, in order to make pressing plate separate rapidly when unclamping, the lower end of described two pressing plates is connected by extension spring.Give pressing plate restoring force like this, pressing plate can be flicked after unclamping cursor, prevent the interference of pickup.
Preferably, described V-block on be provided with block for limiting camshaft location; The ladder place of camshaft can be propped up by the setting of block fast, camshaft working (machining) efficiency is improved.
Preferably, described telescopic stand is made up of U-shaped seat and expansion link, is embedded in U-shaped seat below expansion link by spring, by the effect of spring, the support on supporting seat is acted on below camshaft as supplemental support.
Accompanying drawing explanation
Fig. 1 is Camshaft Key Seat processing milling machine clamp structure schematic diagram of the present utility model;
Fig. 2 is another structural representation of Camshaft Key Seat processing milling machine fixture of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
As depicted in figs. 1 and 2, Camshaft Key Seat processing milling machine fixture, comprise base 12, two primary clamp body clamp body being arranged on base 12 both sides and the supporting seat be arranged in the middle part of base, primary clamp body clamp body comprises matrix 8, V-block 3, voussoir 7, pressing plate 2 and cursor 5, matrix 8 is U-shaped shelf structure, vertical bar hole is provided with below voussoir 7, protuberance in the middle of matrix 8 arranges a pin rod, bar hole and pin rod are slidably matched, V-block 3 is bolted on matrix 8 upper surface, two block pressur plates 2 with voussoir 7 for symmetry axis is hinged on matrix 8, formation inclined-plane is widened downwards gradually in voussoir 7 lower end, pressing plate 2 lower end forms fore-set 10 by bolt and offsets with inclined-plane, the relative formation of two block pressur plates 2 clamps the chuck of camshaft, be hinged on U-shaped frame by ratchet mechanism 4 in the middle part of cursor 5, cursor 5 one end is hinged on voussoir 7 upper end, cursor 5 the other end arranges handle and unclamps the depression bar 6 of ratchet mechanism 4.
The lower end of two pressing plates 2 is connected by extension spring 10; Give pressing plate 2 one restoring forces like this, pressing plate 2 can be flicked after unclamping cursor 5, prevent the interference of pickup.V-block 3 is provided with the block 11 for limiting camshaft 1 position; The ladder place of camshaft 1 can be propped up by the setting of block 11 fast, camshaft 1 working (machining) efficiency is improved.Supporting seat comprises and to form one U-shaped seat 13, expansion link 14 and support 15 with base 12; Be embedded in U-shaped seat 13 by spring below expansion link 14, support 15 is fixed on expansion link 14.
Camshaft 1 is placed in primary clamp body clamp body with on supporting seat, by pulling cursor 5 downwards, cursor 5 drives voussoir 7 to move up, the below of voussoir 7 is gradually to both sides expansion, and pressing plate 2 is rotated around pin joint, and the upper end of two pressing plates 2 is gradually near camshaft 1, by pressing plate 2, camshaft 1 is clamped, camshaft 1, by platen clamp, only leaves processing end face, processes for milling cutter.And under the effect of ratchet mechanism 4, cursor 5 one-directional rotation also keeps the state of cursor 5, makes pressing plate 2 continue to compress camshaft 1; Realize unclamping fast, only need to be unclamped by the ratchet of depression bar 6 by ratchet, cursor 4 lifts and voussoir 7 is declined, and voussoir 7 declines and pressing plate 2 is flicked to both sides, thus unclamps camshaft 1.
