Description

Anchor clamps

Technical field

The present invention relates to a kind of anchor clamps.

Background technology

Often need carry out processing such as milling, boring to some miniature parts in the prior art, clamping method commonly used is to carry out single clamping, processing through flat-nose pliers, and production efficiency is low.

Summary of the invention

The invention provides a kind of anchor clamps that once can fix a plurality of miniature parts, effectively reduced the number of times of clamping, enhance productivity.

The technical solution adopted for the present invention to solve the technical problems is: the invention provides a kind of anchor clamps; Said anchor clamps comprise base and the fixedly briquetting that is fixed on upper surface one end of base; Said fixedly briquetting is connected with at least two perpendicular guide rails; Said two guide rails laterally arrange; The wiper block that can slide along two guide rails is arranged on said two guide rails, and said wiper block is at least one, said wiper block and fixedly briquetting laterally arrange; Said wiper block and fixedly be relatively set with at least two grooves that can block part on the briquetting, said base be provided with thrust unit that can promote wiper block and the locking device that can lock wiper block away from a fixing end of briquetting.

Further; Said thrust unit and locking device are made up of lead-screw, driving handle, tie down screw, set lever and support plate; Said base be provided with support plate away from a fixing side of briquetting; Fix with attachment screw between said support plate and the base, the top of said support plate is provided with three screwed holes, and said three screwed holes are that the center is symmetrically distributed with the longitudinal centre line of second wiper block; Screwed hole and the with it threaded engagement of said lead-screw in the middle of placing; Said tie down screw places the screwed hole and the threaded engagement with it on both sides, and the end away from backing plate of said lead-screw is provided with driving handle, and the end away from backing plate of said tie down screw is provided with set lever.

Further, in the side cross direction profiles away from first wiper block of said second wiper block three backing plates are arranged, the position and the screwed hole of said three backing plates adapt.

Further, said fixedly briquetting is provided with spring with a wiper block side in opposite directions.

Further, said guide rail is a dovetail groove.

The beneficial effect of the technical scheme that the embodiment of the invention provides is: because wiper block and fixedly be relatively set with at least two grooves that can block part on the briquetting, and being provided with the thrust unit that can promote wiper block and can locking the locking device of wiper block away from a fixing end of briquetting at base.Therefore, anchor clamps provided by the invention once can be clamped two miniature parts at least, have reduced clamping times, improved production efficiency, and clamp structure provided by the invention are simple, and are simple to operate, are easy to use on a large scale.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.

Fig. 1 is the structural representation of the anchor clamps that provide of the embodiment of the invention;

Fig. 2 is the front view of Fig. 1;

Fig. 3 is the A-A face cutaway view of Fig. 1;

Fig. 4 is the B-B face cutaway view of Fig. 1.

The specific embodiment

For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.

Referring to Fig. 1-Fig. 4, be set with fixedly briquetting 3 at an end of the upper surface of base 13, the vertical fixedly briquetting 3 that connects of an end of guide rail 1, having on the guide rail 1 can be along the wiper block of guide rail 1 slip.Guide rail 1 can be the arbitrary structures that wiper block is moved along straight path, such as is dovetail groove.Guide rail 1 is minimum to be to be two an of near symmetrical with the wiper block longitudinal centre line, with the slip of guaranteeing that wiper block is stable.Wiper block is with fixedly briquetting 3 is parallel; Wiper block comprises first wiper block 5 and second wiper block 6; Fixedly be oppositely arranged fluted 2 on briquetting 3 and first wiper block 5, first wiper block 5 and second wiper block 6; Groove 2 is side by side a plurality of, and groove 2 can be the arbitrary shape that can block miniature parts, such as is " V " shape groove or dovetail groove.Be provided with support plate 7 at base 13 away from a fixing side of briquetting 3; Fixing between support plate 7 and the base 13 with attachment screw 11; Support plate 7 tops are provided with three screwed holes; Screwed hole is that the center is symmetrically distributed with the longitudinal centre line of second wiper block 6, screwed hole in the middle of lead-screw 10 places and threaded engagement with it, and tie down screw 12 places the screwed hole on both sides and threaded engagement with it; The side cross direction profiles away from first wiper block 5 at second wiper block 6 has three backing plates 8, and the position and the screwed hole of backing plate 8 adapt.End away from backing plate 8 of lead-screw 10 is provided with driving handle 9, and the end away from backing plate 8 of tie down screw 12 is provided with set lever 14.Fixedly briquetting 3 is provided with spring 4 with first wiper block 5 side in opposite directions is provided with spring 4, the first wiper blocks 5 with second wiper block 6 side in opposite directions.

Above-mentioned lead-screw 10, driving handle 9, tie down screw 12, set lever 14 and support plate 7 constitute thrust unit of the present invention and locking devices; Thrust unit and locking device can be other structures, can wiper block be fixed on and want the position fixed as long as thrust unit can promote wiper block, locking device.

During work; Part 15 is placed in the space of groove 2 formation, shakes driving handle 9, lead-screw 10 promotes second wiper block 6 and moves forward; Second wiper block 6 promotes first row's part 15; First row's part 15 promotes first wiper block 5 and moves, and first wiper block 5 promotes second row's part 15 and presses to fixedly briquetting 3, reaches the effect of preliminary locking.Shake set lever 14, make tie down screw 12 withstand the backing plate 8 on both sides, part 15 is fixed in the groove 2; Part 15 is processed, after part 15 machines, unclamped lead-screw 10 and tie down screw 12; Under the effect of spring 4, part 15 unclamps, and takes out part 15.Can certainly not have spring 4, manually fixedly compressing tablet 3, the first slip compressing tablet 5 and the second slip compressing tablet left and get final product in 6 minutes when needs take out part 15 like this.

The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
