Hand automatic double clamp vise

The invention provides a technical field of a vise, in particular to provide a hand automatic double clamp vise.

According to the first and second figures, the invention patent application No. 101112173, "Hand automatic double clamp vise (1)", which was originally filed by the inventor of the present invention, includes a vise body provided with a a front clamping seat group and a rear clamping seat group, the vise body is provided with a fixing block in the middle of the two clamping seat groups, the vise body is provided with an axial guiding rail, and the guiding rail is provided for the sliding of the two clamping seat groups; a long screw 11 In the latter half, a first external thread is provided, and the rear clamping seat set is provided with a first internal thread which is screwed on the first external thread, and a concave portion and a smaller rod portion are arranged in the first half of the long screw 11 and the long screw 11 The front end is screwed to a pull rod, the pull rod is provided with a set of connecting holes, and the connecting hole is provided for manual one-handed connection transmission; a short screw 12, the long screw 11 has a smaller rod portion to be sleeved with the short screw 12, and the short screw 12 is peripherally disposed a second external thread, the front clamping seat set is provided with a second internal thread which is screwed on the second external thread, and the first screw and the second external thread of the long screw 11 are opposite to the spiral of the external screw, and the short screw 12 is 12 The rear end is provided with a groove for receiving a first spring top against the inner surface of the groove and a concave vertical surface, and the front end of the short screw 12 is matched with the long screw 11 is provided with an outer circumferential surface a foolproof member, the anti-dwelling member enables the long screw 11 to rotate the power to be transmitted to the short screw 12 by the foolproof member, and keeps the short screw 12 still having elastic elasticity; a cylinder, the front end of the long screw 11 is penetrated a piston-through hole of the cylinder, a guide hole is arranged on each side of the hydraulic pressure cover of the pressure cylinder, and the vise body is provided with two guide rods toward the two guide holes, and is disposed on one side of the guide rod after the guide rod penetrates the guide hole a second and third spring tops are pressed against the oil pressure cover, and the two ends of the piston of the pressure cylinder respectively abut against the short screw 12 and the tie rod fixed with the long screw 11; an empty hydraulic system is connected to the hydraulic pressure supply of the pressure cylinder The oil and a gas pipe are connected to the pressure cylinder and the gas pressure cap supplies the high pressure gas of the pressure cylinder; accordingly, when the manual rotation of the handle drives the long screw 11, the power is transmitted to the short screw 12 synchronously by the foolproof member, thereby driving the front and rear When the clamping seat group is clamped, when the rear clamping seat group cooperates with the fixing block to first clamp the workpiece, continuing to rotate the long screw 11 will start to compress the second and third springs and push the short screw 12 to compress the first spring until the thin workpiece is clamped. When the manual rotation of the handle drives the long screw 11, the power is prevented by the foolproof member Passing to the short screw 12 synchronously rotating, thereby driving the front and rear clamping seat groups to be clamped. When the front clamping seat group cooperates with the fixing block to first clamp the workpiece, the rotation of the short screw 12 will start to push until the thin workpiece is clamped; Automatic clamping operation, when the rear clamping seat group cooperates with the fixing block to clamp the workpiece first, the pressure cylinder can still shorten the screw 12 to clamp different thickness workpieces by the first spring compression and the second and third spring compressions; When the front clamp seat group cooperates with the fixed block to clamp the workpiece first, the pressure cylinder can continue to pressurize, and different thick workpieces can be clamped differently.

However, there is still a sparseness in the invention of the former case, although the vise can To clamp two thick and thin workpieces, but the vise is further provided with a first spring 13 to abut against the inner surface of the short screw 12 and the concave vertical surface of the long screw 11, and further has a foolproof member for preventing the fool The member causes the long screw 11 to rotate the power to be transmitted to the short screw 12 by the foolproof member, and keeps the short screw 12 still having the elasticity of expansion and contraction, wherein the foolproof member includes the front end of the short screw 12 and is equally divided into four elongated shapes. The semi-spherical groove 121, the outer peripheral surface of the long screw 11 is provided with four semi-spherical ball grooves 111 corresponding to the end of the elongated semi-spherical ball groove 121, so as to fit the four semi-spherical ball grooves 121 to accommodate four positioning elements or balls 14 or The rod is such that the rotational force of the long screw 11 can be transmitted to the short screw 12 by four positioning elements or balls 14 or rods, and the short screw 12 still has elasticity of expansion and contraction; the foolproof member further includes a screw 15, the aforementioned short When the screw 12 compresses the first spring 13 and retracts too much, the four positioning elements or the balls 14 or the rods are exposed and dropped, and the long screws 11 are retracted at the limit of the short screw 12 which does not expose the positioning member or the ball 14 or the rod. The position is provided with a screw hole 112, and the aforementioned screw 15 is locked. Short screw 12 continues to shrink. However, the front clamp seat group and the rear clamp seat group of the vise are retracted to the most open condition, and the multiple force device that accidentally starts the air hydraulic system will generate an excessive stroke and thereby destroy the screw 15 of the foolproof device, and make the four The positioning elements or balls 14 or rods are exposed and dropped to cause damage. The four positioning elements or the ball 14 or the rod, the front end of the short screw 12 are equally provided with four elongated semi-spherical ball grooves 121, and the outer peripheral surface of the long screw 11 corresponds to the end of the elongated semi-spherical ball groove 121.
