Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a tool clamp capable of processing a plurality of workpieces comprises a base body 1, an inner groove 2 is formed in the middle of the base body 1, the periphery of the inner groove 2 is provided with an open end, the upper end of the base body 1 is uniformly provided with two rows of through holes, the through holes are communicated with the inner groove 2, an H-shaped support 6 is arranged in the inner groove 2, two rows of movable rods 4 are uniformly arranged at the upper end of the H-shaped support 6, the upper ends of the movable rods 4 extend upwards and penetrate out of the through holes to the upper end of the base body 1 in a one-to-one correspondence manner, the lower ends of the movable rods 4 are inserted into the H-shaped support 6 and are rotatably connected with the H-shaped support 6, transition plates 3 are fixedly connected at the tops of the movable rods 4, four sliding grooves 10 are uniformly formed in one circle outside the movable rods 4, sliding sleeves 8 are sleeved outside the movable rods 4 and inside the inner groove 2, a limiting block 11 is fixedly connected with the inner wall of the sliding sleeves 8, a connecting strip 9 is arranged between the front sliding sleeve 8 and the rear sleeve 8, a screw rod 5 is arranged in the middle of the inner groove 2, the bottom of a screw rod 5 is inserted into the bottom of an inner groove 2 and is rotationally connected with the bottom of the inner groove 2, the upper end of the screw rod 5 extends upwards and penetrates through an H-shaped support 6 to the upper end of a base body 1, threads are arranged on the outer side of the screw rod 5 and positioned in the inner groove 2, a plurality of positioning holes are formed between left and right adjacent through holes, a connecting strip 9 is hinged with sliding sleeves 8 at the front end and the rear end through hinges, the upper end of the screw rod 5 is rotationally connected with the upper end of the base body 1, the middle part of the H-shaped support 6 is in threaded connection with the screw rod 5, a spring 7 is sleeved between the sliding sleeves 8 and the H-shaped support 6 on the outer side of a movable rod 4, the upper end of the spring 7 is contacted with the bottom of the sliding sleeve 8, and the lower end of the spring 7 is contacted with the H-shaped support 6;

at first with anchor clamps installation on the lathe, when many work pieces need to be processed, earlier rotate screw rod 5 in 1 upper end of base member through using the spanner, because the lower extreme all rotates in 1 inside rotation of base member and connects on screw rod 5, can't remove, H type support 6 with 5 threaded connection of screw rod can be driven the rebound by screw rod 5 like this, and H type support 6 slides with base member 1 through many movable rods 4 of upper end, thereby at the in-process that moves on H type support 6, movable rod 4 can open spacing effect, let H type support 6 can not the off normal, all movable rod 4 can synchronous rebound like this, H type support 6 shifts up simultaneously and can extrude spring 7, make sliding sleeve 8 hug closely 1 top of base member.

When the movable rods 4 move to the distance between the transition plate 3 and the base 1 to place a workpiece, the workpiece is placed between the left and right adjacent movable rods 4 and clamped through the positioning holes, then one of the front and rear adjacent transition plates 3 is rotated to enable the two ends of the transition plate 3 to rotate to the position capable of clamping the workpiece, at the moment, the movable rods 4 at the lower end of the transition plate 3 can rotate along with the transition plate 3, as the limiting blocks 11 inside the sliding sleeves 8 are arranged inside the sliding grooves 10 and can only slide up and down, the sliding sleeves 8 can rotate along with the movable rods 4, the front and rear adjacent sliding sleeves 8 can synchronously rotate through the connecting strips 9, the transition plates 3 can synchronously rotate, the workpiece is positioned between the left and right adjacent movable rods 4, and the transition plate 3 can clamp the workpiece without rotating by an overlarge angle, therefore, when a workpiece is clamped, the adjustment of all the transition plates 3 can be completed only by rotating one row of the transition plates 3.

Finally, the screw rod 5 is rotated reversely, so that the screw rod 5 drives the H-shaped support 6 to move downwards, the movable rod 4 and the transition plate 3 are further driven to move downwards, the transition plate 3 clamps the workpiece, the workpiece can be clamped and loosened by rotating the screw rod 5 forwards and backwards, the workpiece can be placed and disassembled by adjusting the transition plate 3 at the right end, the clamping and the disassembling of the workpieces are very conveniently carried out, and the used time is greatly reduced.

The working principle is as follows: the H-shaped support 6 moves upwards by rotating the screw rod 5, and then the support 6 can drive the movable rod 4 to move upwards, so that the upper ends of the transition plate 3 and the base body 1 are spaced by a proper distance, then a workpiece to be processed is placed between the transition plate 3 and the base body 1, and the angle of the transition plate 3 is adjusted by rotating the movable rod 4, so that the workpiece can be clamped more stably, and because the adjacent movable rods 4 are connected through the connecting strip 9, all the angle adjustment of the transition plate 3 can be completed by rotating one row of the movable rods 9, and then the screw rod 5 is rotated in the opposite direction, so that the H-shaped support 6 moves downwards, the transition plate 3 can move downwards and clamp the workpiece, the transition plate 3 is synchronously clamped through the H-shaped support 6, and the time for clamping and disassembling the workpiece can be reduced.
