Abstract
The invention relates to a clamping workpiece on a working table for lathes and other machining equipment, in particular to a table clamp, and solves the problems that the conventional clamping workpiece has limited use range or a special clamp cannot be repeatedly used, the machining operation efficiency is low, the machining precision is hard to guarantee, and the like. The table clamp consists of a table panel and a pressing device on the table panel, wherein the pressing device consists of a height adjustable supporting piece, a pressing block which is supported on the supporting piece, a pressing lever and a supporting rod; the contact surface of the pressing block and the supporting piece is a curved surface and a pressing handle is arranged on the pressing block; one end of the pressing lever is hinged with the pressing block, and a rectangular gap is formed at the other end of the pressing lever; one end of the supporting rod is made into an inverted T-shape which is matched with an inverted T-shaped groove on the table panel; and symmetrical grooves are formed on the end faces of two sides of the supporting rod. The table clamp has wide application range; the volume range of workpieces clamped by the clamp is doubled; and the clamping positions of irregular workpieces are flexible. The table clamp has the characteristics of simple and reliable structure, convenient and fast operation and repeated use.
Description
Technical field
The present invention relates to the clamping work pieces on the work top of machining apparatus such as milling machine, drilling machine, planer, lathe, be specially table clamp.
Background technology
Milling machine, drilling machine, planer, lathe etc. have the machining apparatus of work top; Clamping work pieces commonly used is to be fixed on special fixture that stock vice, dividing head or specialized designs on the work top make etc., and stock vice and dividing head are applicable to be processed profile comparatively Founder, the less occasion of volume, and the special-shaped workpiece that volume is bigger need design and produce special fixture usually; Not only improve processing cost, extension of the work cycle, increasing working strength; And the anchor clamps of making are comparatively simple and easy, coarse usually, can not reuse, and this special fixture adjustability when workpiece pressing is poor simultaneously; The process operation inefficiency; Guarantee comparatively difficulty of machining accuracy, need subsequent use different size parallels quantity big, it is not convenient to operate.The more important thing is anchor clamps commonly used in that to clamp overall dimensions bigger, during to be processed less situation, need the auxiliary bracing frame etc. of making, the additional work amount is big, operating difficulties.
Summary of the invention
The present invention is limited or special fixture can not be reused, process operation inefficiency, machining accuracy are difficult to problems such as assurance in order to solve the existing clamping work pieces scope of application, and a kind of table clamp is provided.
The present invention adopts following technical scheme to realize: table clamp is made up of the hold down gag on deck plate and the deck plate; Deck plate four limits are provided with open slot, and the deck plate upper surface has the inverted T-slot of horizontal, vertical intersection; Hold down gag by be positioned at the adjustable for height support member on the deck plate, briquetting, clamping lever and the support bar that is supported on the support member constitutes; The contact-making surface of briquetting and support member is to have pressure handle on cambered surface and the briquetting; One end of clamping lever is hinged through bearing pin and briquetting; The other end of clamping lever has the rectangle gap; One end of support bar process with deck plate on the inverted T-shaped that cooperates of inverted T-slot, have groove of (a plurality of) symmetry on the both sides end face of support bar, support bar penetrates the rectangle gap of the clamping lever other end and makes clamping lever put into the groove on the end face of support bar both sides.During use; Overall dimensions and workpiece position to be processed according to be processed; The open slot of deck plate through its four limit is connected with bolt with the machining apparatus work top; Then with the support bar of hold down gag through an end of its inverted T-shaped with cooperating of inverted T-slot be through at the suitable workpiece pressing of deck plate position on the deck plate, adjustable for height support member is adjusted to proper height, the gap end of clamping lever is interspersed in the appropriate location of support bar and makes clamping lever be positioned at the groove on the end face of corresponding support bar both sides; The gap end of clamping lever places on to be processed; The briquetting of the clamping lever other end places on the adjustable for height support member, and the pressure handle on the briquetting is depressed, and clamping lever will be that fulcrum prizes with the support bar (is that the briquetting end raises; The gap end descends), the gap end of clamping lever is compressed or fastening to be processed.When workpiece to be processed is big, can adopt many covers to compress device, need hold down gag 6-8 covers to cooperate jointly usually for large-scale to be processed and realize compressing to be processed with platform tool plate.
The table clamp scope of application of the present invention is extensive, but the volume range of clamping work pieces be multiplied, the clamped position of special-shaped workpiece is comparatively flexible, has characteristics simple and reliable for structure, simple operation, it is more reliable, reusable that workpiece is clamped.

The specific embodiment
Table clamp is made up of the hold down gag on deck plate 1 and the deck plate; Deck plate 1 four limits are provided with open slot 2, and deck plate 1 upper surface has the inverted T-slot 3 of horizontal, vertical intersection; Hold down gag by be positioned at the adjustable for height support member 4 on the deck plate 1, briquetting 5, clamping lever 6 and the support bar 7 that is supported on the support member 4 constitutes; Briquetting 5 is to have pressure handle 8 on cambered surface and the briquetting 5 with the contact-making surface of support member 4; One end of clamping lever 6 is hinged through bearing pin and briquetting 5; The other end of clamping lever 6 has the rectangle gap; One end of support bar 7 process with deck plate 1 on the inverted T-shaped that cooperates of inverted T-slot, have groove of (a plurality of) symmetry on the both sides end face of support bar 7, support bar 7 penetrates the rectangle gap of clamping lever 6 other ends and makes clamping lever 6 put into the groove on the end face of support bar both sides.During practical implementation, described adjustable for height support member 4 can adopt multiple version, and the contact-making surface of briquetting (promptly with) can go up and down as long as its supporting surface.In this embodiment; Adjustable for height support member 4 is made up of last back-up block, following back-up block; The contact-making surface of last back-up block and following back-up block is and the angled inclined-plane of deck plate 1 upper surface, and has the latch that cooperatively interacts on the contact-making surface of last back-up block and following back-up block.Last back-up block can move up and down and locate through latch along contact-making surface, thereby the height of realizing support member is regulated.The bottom of following back-up block be provided with deck plate 1 on the inverted T-shaped tooth that cooperates of inverted T-slot, can help the stable of hold down gag with playing back-up block to be fastened on the deck plate like this.
